    The praying mantis, Mantis religiosa, is unique in possessing a single, tympanal auditory organ located in the ventral midline of its body between the metathoracic coxae. The ear is in a deep groove and consists of two tympana facing each other and backed by large air sacs. Neural transduction takes place in a structure at the anterior end of the groove. This tympanal organ contains 32 chordotonal sensilla organized into three groups, two of which are 180 degrees out of line with the one attaching directly to the tympanum. Innervation is provided by Nerve root 7 from the metathoracic ganglion. Cobalt backfills show that the auditory neuropile is a series of finger-like projections terminating ipsilaterally near the midline, primarily near DC III and SMC. The auditory neuropile thus differs from the pattern common to all other insects previously studied.

    Abstract The praying mantis is an insect which relies on vision for capturing prey, avoiding being eaten and for spatial orientation. It is well known for its ability to use stereopsis for estimating the distance of objects. The neuronal substrate mediating visually driven behaviors, however, is not very well investigated. To provide a basis for future functional studies, we analyzed the anatomical organization of visual neuropils in the brain of the praying mantis Hierodula membranacea and provide supporting evidence from a second species, Rhombodera basalis, with particular focus on the lobula complex (LOX). Neuropils were three‐dimensionally reconstructed from synapsin‐immunostained whole mount brains. The neuropil organization and the pattern of γ‐aminobutyric acid immunostaining of the medulla and LOX were compared between the praying mantis and two related polyneopteran species, the Madeira cockroach and the desert locust. The investigated visual neuropils of the praying mantis are highly structured. Unlike in most insects the LOX of the praying mantis consists of five nested neuropils with at least one neuropil not present in the cockroach or locust. Overall, the mantis LOX is more similar to the LOX of the locust than the more closely related cockroach suggesting that the sensory ecology plays a stronger role than the phylogenetic distance of the three species in structuring this center of visual information processing.

    Abstract This study provides a comprehensive review of historical morphological nomenclature used for praying mantis (Mantodea) morphology, which includes citations, original use, and assignment of homology. All referenced structures across historical works correspond to a proposed standard term for use in all subsequent works pertaining to praying mantis morphology and systematics. The new standards are presented with a verbal description in a glossary as well as indicated on illustrations and images. In the vast majority of cases, originally used terms were adopted as the new standard. In addition, historical morphological topographical homology conjectures are considered with discussion on modern interpretations. A new standardized formulation to present foreleg femoral and tibial spines is proposed for clarity based on previous works. In addition, descriptions for methods of collection, curation, genital complex dissection, and labeling are provided to aid in the proper preservation and storage of specimens for longevity and ease of study. Due to the lack of consistent linear morphometric measurement practices in the literature, we have proposed a series of measurements for taxonomic and morphological research. These measurements are presented with figures to provide visual aids with homologous landmarks to ensure compatibility and comparability across the Order. Finally, our proposed method of pinning mantises is presented with a photographical example as well as a video tutorial available at http://mantodearesearch.com. PMID:29200926

    We assessed the differences in appetitive responses to visual stimuli by three species of praying mantis (Insecta: Mantodea), Tenodera aridifolia sinensis, Mantis religiosa, and Cilnia humeralis. Tethered, adult females watched computer generated stimuli (erratically moving disks or linearly moving rectangles) that varied along predetermined parameters. Three responses were scored: tracking, approaching, and striking. Threshold stimulus size (diameter) for tracking and striking at disks ranged from 3.5 deg (C. humeralis) to 7.8 deg (M. religiosa), and from 3.3 deg (C. humeralis) to 11.7 deg (M. religiosa), respectively. Unlike the other species which struck at disks as large as 44 deg, T. a. sinensis displayed a preference for 14 deg disks. Disks moving at 143 deg/s were preferred by all species. M. religiosa exhibited the most approaching behavior, and with T. a. sinensis distinguished between rectangular stimuli moving parallel versus perpendicular to their long axes. C. humeralis did not make this distinction. Stimulus sizes that elicited the target behaviors were not related to mantis size. However, differences in compound eye morphology may be related to species differences: C. humeralis' eyes are farthest apart, and it has an apparently narrower binocular visual field which may affect retinal inputs to movement-sensitive visual interneurons.

  5. Audition in the praying mantis, Mantis religiosa L.: identification of an interneuron mediating ultrasonic hearing.

    1. The praying mantis possesses a single ear located in the ventral midline of the metathorax. We have studied the mantis' auditory nervous system using both extracellular and intracellular techniques and have identified anatomically and physiologically a mirror-image pair of interneurons (MR-501-T3) in the metathoracic ganglion that mediates ultrasonic hearing. 2. MR-501-T3 is tuned broadly to ultrasound with best sensitivity (55-60 dB SPL) between 25 and 45 kHz. Its tuning matches closely that of the whole tympanal nerve. 3. The physiological responses of MR-501-T3 are characterized by: (1) a phasic-tonic firing pattern with a distinctive initial burst at 500-800 spikes/s; (2) minimum latencies of 8-12 ms; (3) no spontaneous activity; (4) sigmoid intensity response curves with a small (10 dB) dynamic range; (5) accurate coding of stimulus duration and of repetition rates up to 60 pps. 4. The ascending axon of MR-501-T3 conducts action potentials at 4 m/s, a rate comparable with some giant fiber systems. 5. MR-501-T3 shows no directional capability. Sound from right and left produce identical responses in both cells of the pair. Neither cutting one tympanal nerve nor removing one hemi-ear leads to different responses in the two cells indicating that they must receive a common input, either from the auditory afferents or from interneurons. We present evidence that the two cells are not directly connected. 6. MR-501-T3 is a large, symmetrical cell with its processes primarily in the intermediate neuropil (lateral ring tract). Its integration segment crosses the midline in the supramedian commissure, and the cell body lies dorsally near the entrance of the leg nerve. The axon travels in the dorsal lateral tract and is one of the largest (17 microns) in the connective. 7. Given the strong anatomical similarities between MR-501-T3 and the G and B cells of the locust, these cells may be homologous. 8. We present arguments based on our physiological results and existing

    Many praying mantis species remain known from type specimens only. The majority of these taxa have vague taxonomic limits, as original descriptions are often very short, making strong emphasis on superficial characters (Rivera 2010). One clear example of this is the Amazonian Mantellias Westwood, 1889, a monotypical genus represented by Mantellias pubicornis Westwood, 1889.

  7. Investigating saccade programming in the praying mantis Tenodera aridifolia using distracter interference paradigms.

    To investigate the saccadic system in the mantis, I applied distracter interference paradigms. These involved presenting the mantis with a fixation target and one or several distracters supposed to affect saccades towards the target. When a single target was presented, a medium-sized target located in its lower visual field elicited higher rates of saccade response. This preference for target size and position was also observed when a target and a distracter were presented simultaneously. That is, the mantis chose and fixated the target rather than a distracter that was much smaller or larger than the target, or was located above the target. Furthermore, the mantis' preference was not affected by increasing the number of distracters. However, the presence of the distracter decreased the occurrence rate of saccade and increased the response time to saccade. I conclude that distracter interference paradigms are an effective way of investigating the visual processing underlying saccade generation in the mantis. Possible mechanisms of saccade generation in the mantis are discussed.

  8. Small or far away? Size and distance perception in the praying mantis

    Stereo or ‘3D’ vision is an important but costly process seen in several evolutionarily distinct lineages including primates, birds and insects. Many selective advantages could have led to the evolution of stereo vision, including range finding, camouflage breaking and estimation of object size. In this paper, we investigate the possibility that stereo vision enables praying mantises to estimate the size of prey by using a combination of disparity cues and angular size cues. We used a recently developed insect 3D cinema paradigm to present mantises with virtual prey having differing disparity and angular size cues. We predicted that if they were able to use these cues to gauge the absolute size of objects, we should see evidence for size constancy where they would strike preferentially at prey of a particular physical size, across a range of simulated distances. We found that mantises struck most often when disparity cues implied a prey distance of 2.5 cm; increasing the implied distance caused a significant reduction in the number of strikes. We, however, found no evidence for size constancy. There was a significant interaction effect of the simulated distance and angular size on the number of strikes made by the mantis but this was not in the direction predicted by size constancy. This indicates that mantises do not use their stereo vision to estimate object size. We conclude that other selective advantages, not size constancy, have driven the evolution of stereo vision in the praying mantis. This article is part of the themed issue ‘Vision in our three-dimensional world’. PMID:27269605

  9. Role of a looming-sensitive neuron in triggering the defense behavior of the praying mantis Tenodera aridifolia.

    In responses to looming objects, the praying mantis shows a defense behavior, which consists of retracting forelegs under the prothorax. The role of a looming-sensitive neuron in triggering this behavior was investigated by simultaneously recording the activity and behavioral responses of the neuron. The mantis initiated the defense behavior earlier in response to larger and slower looming stimuli. The time remaining to collision at defense initiation was linearly correlated with the ratio of the half-size of an approaching object to its speed (l/|v|), suggesting that the defense behavior occurred a fixed delay after the stimuli had reached a fixed angular threshold. Furthermore, the results suggested that high-frequency spikes of the looming-sensitive neuron were involved in triggering the defense behavior: the distribution of maximum firing rate for trials with defense was shifted to larger rates compared with trials without defense; the firing rate of the neuron exceeded 150 Hz ∼100 ms before the defense initiation regardless of stimulus parameters; when a looming stimulus ceased approach prematurely, high-frequency spikes were removed, and the occurrence of defense was reduced.

    Spectromicroscopy combines spectral data with microscopy, where typical datasets consist of a stack of images taken across a range of energies over a microscopic region of the sample. Manual analysis of these complex datasets can be time-consuming, and can miss the important traits in the data. With this in mind we have developed MANTiS, an open-source tool developed in Python for spectromicroscopy data analysis. The backbone of the package involves principal component analysis and cluster analysis, classifying pixels according to spectral similarity. Our goal is to provide a data analysis tool which is comprehensive, yet intuitive and easy to use. MANTiS is designed to lead the user through the analysis using story boards that describe each step in detail so that both experienced users and beginners are able to analyze their own data independently. These capabilities are illustrated through analysis of hard X-ray imaging of iron in Roman ceramics, and soft X-ray imaging of a malaria-infected red blood cell.

    Sampling cores requires the controlled breakoff of the core at a known location with respect to the drill end. An additional problem is designing a mechanism that can be implemented at a small scale, yet is robust and versatile enough to be used for a variety of core samples. The new design consists of a set of tubes (a drill tube, an outer tube, and an inner tube) and means of sliding the inner and outer tubes axially relative to each other. Additionally, a sample tube can be housed inside the inner tube for storing the sample. The inner tube fits inside the outer tube, which fits inside the drill tube. The inner and outer tubes can move axially relative to each other. The inner tube presents two lamellae with two opposing grabbing teeth and one pushing tooth. The pushing tooth is offset axially from the grabbing teeth. The teeth can move radially and their motion is controlled by the outer tube. The outer tube presents two lamellae with radial extrusions to control the inner tube lamellae motion. In breaking the core, the mechanism creates two support points (the grabbing teeth and the bit tip) and one push point. The core is broken in bending. The grabbing teeth can also act as a core retention mechanism. The praying mantis that is disclosed herein is an active core breaking/retention mechanism that requires only one additional actuator other than the drilling actuator. It can break cores that are attached to the borehole bottom as

    PART A: The Manti landslide is in Manti Canyon on the west side of the Wasatch Plateau in central Utah. In early June 1974, coincident with the melting of a snowpack, a rock slump/debris flow occurred on the south rim of Manti Canyon. Part of the slumped material mixed with meltwater and mobilized into a series of debris flows that traveled down the slope a distance of as much as 1.2 km. Most of the flows were deposited either at the base of the steep rocks of the canyon rim or at the site of an old, silted reservoir. A small part of the debris flow deposit stopped on the head of the very large, relatively inactive Manti landslide. The upper part of the landslide began moving as cracks propagated downslope. A little more than a year later, August 1975, movement extended the full length of the old landslide, and about 19 million m 3 of debris about 3 km long and as much as 800 m wide threatened to block the canyon. The upper part of the landslide apparently had moved small amounts between 1939 and 1974. This part of the landslide, identifiable on pre-1974 aerial photographs, consisted of well-defined linears on the landslide flanks and two large internal toe bulges about 2 km downslope from the head. The abrupt reactivation in 1974 proceeded quickly after the debris flows had provided a surcharge in the head and crown area. Movement propagated downslope at 4-5 m/h for the first few days following reactivation. During 1974, the reactivation probably encompassed all the parts of the landslide that had moved small amounts between 1939 and 1974. Movement nearly or completely stopped during the winter of 1974-75, but began again in the spring of 1975. The landslide enlarged from the flanks of the internal toe bulges to Manti Creek at a rate of 2-3 m/h. Movement stopped again during the winter of 1975-76 and began again in the spring of 1976. Thereafter, the displacements have been small compared to earlier. The displacement rates for the landslide were variable depending

    Male praying mantises are forced into the ultimate trade-off of mating versus complete loss of future reproduction if they fall prey to a female. The balance of this trade-off will depend both on (1) the level of predatory risk imposed by females and (2) the frequency of mating opportunities for males. We report the results of a set of experiments that examine the effects of these two variables on male risk-taking behavior and the frequency of sexual cannibalism in the praying mantis Tenodera sinensis. We experimentally altered the rate at which males encountered females and measured male approach and courtship behavior under conditions of high and low risk of being attacked by females. We show that male risk taking depends on prior access to females. Males with restricted access to females showed greater risk-taking behavior. When males were given daily female encounters, they responded to greater female-imposed risk by slowing their rate of approach and remained a greater distance from a potential mate. In contrast, males without recent access to mates were greater risk-takers; they approached females more rapidly and to closer proximity, regardless of risk. In a second experiment, we altered male encounter rate with females and measured rates of sexual cannibalism when paired with hungry or well-fed females. Greater risk-taking behavior by males with low mate encounter rates resulted in high rates of sexual cannibalism when these males were paired with hungry females. PMID:22558146

    Practitioners of comparative genomics face huge analytical challenges as whole genome sequences and functional/expression data accumulate. Furthermore, the field would greatly benefit from a better integration of this wealth of data with evolutionary concepts. Here, we present MANTIS, a relational database for the analysis of (i) gains and losses of genes on specific branches of the metazoan phylogeny, (ii) reconstructed genome content of ancestral species and (iii) over- or under-representation of functions/processes and tissue specificity of gained, duplicated and lost genes. MANTIS estimates the most likely positions of gene losses on the true phylogeny using a maximum-likelihood function. A user-friendly interface and an extensive query system allow to investigate questions pertaining to gene identity, phylogenetic mapping and function/expression parameters. MANTIS is freely available at http://www.mantisdb.org and constitutes the missing link between multi-species genome comparisons and functional analyses.

    Sequence-level searches on large collections of RNA sequencing experiments, such as the NCBI Sequence Read Archive (SRA), would enable one to ask many questions about the expression or variation of a given transcript in a population. Existing approaches, such as the sequence Bloom tree, suffer from fundamental limitations of the Bloom filter, resulting in slow build and query times, less-than-optimal space usage, and potentially large numbers of false-positives. This paper introduces Mantis, a space-efficient system that uses new data structures to index thousands of raw-read experiments and facilitates large-scale sequence searches. In our evaluation, index construction with Mantis is 6× faster and yields a 20% smaller index than the state-of-the-art split sequence Bloom tree (SSBT). For queries, Mantis is 6-108× faster than SSBT and has no false-positives or -negatives. For example, Mantis was able to search for all 200,400 known human transcripts in an index of 2,652 RNA sequencing experiments in 82 min; SSBT took close to 4 days. Copyright © 2018 Elsevier Inc.

    The asteroids preserve information from the earliest times in solar system history, with compositions in the population reflecting the material in the solar nebula and experiencing a wide range of temperatures. Today they experience ongoing processes, some of which are shared with larger bodies but some of which are unique to their size regime. They are critical to humanity's future as potential threats, resource sites, and targets for human visitation. However, over twenty years since the first spacecraft encounters with asteroids, they remain poorly understood. The mission we propose here, the Main-belt Asteroid and NEO Tour with Imaging and Spectroscopy (MANTIS), explores the diversity of asteroids to understand our solar system's past history, its present processes, and future opportunities and hazards. MANTIS addresses many of NASA's highest priorities as laid out in its 2014 Science Plan and provides additional benefit to the Planetary Defense and Human Exploration communities via a low-risk, cost-effective tour of the near-Earth and inner asteroid belt. MANTIS visits the materials that witnessed solar system formation and its earliest history, addressing the NASA goal of exploring and observing the objects in the solar system to understand how they formed and evolve. MANTIS measures OH, water, and organic materials via several complementary techniques, visiting and sampling objects known to have hydrated minerals and addressing the NASA goal of improving our understanding of the origin and evolution of life on Earth. MANTIS studies the geology and geophysics of nine diverse asteroids, with compositions ranging from water-rich to metallic, representatives of both binary and non-binary asteroids, and sizes covering over two orders of magnitude, providing unique information about the chemical and physical processes shaping the asteroids, addressing the NASA goal of advancing the understanding of how the chemical and physical processes in our solar system

The code solves for the electromagnetic fields in three dimensions near the antenna structure with a realistic plasma load. Fourier analysis is used in the two dimensions that are tangential to the plasma surface and backwall. The third dimension is handled analytically in a vacuum region with a general impedance match at the plasma-vacuum interface. The impedance tensor is calculated for a slab plasma using the ORION-lD code with all three electric field components included and warm plasma corrections. The codemore » permits the modeling of complicated antenna structures by superposing currents that flow on the surfaces of rectangular parallelepipeds. Specified current elements have feeders that continuously connect the current flowing from the ends of the strap to the feeders. The elements may have an arbitrary orientation with respect to the static magnetic field. Currents are permitted to vary along the length of the current strap and feeders. Parameters that describe this current variation can be adjusted to approximately satisfy boundary conditions on the current elements.

    hybridMANTIS is a Monte Carlo package for modeling indirect x-ray imagers using columnar geometry based on a hybrid concept that maximizes the utilization of available CPU and graphics processing unit processors in a workstation. The authors compare hybridMANTIS x-ray response simulations to previously published MANTIS and experimental data for four cesium iodide scintillator screens. These screens have a variety of reflective and absorptive surfaces with different thicknesses. The authors analyze hybridMANTIS results in terms of modulation transfer function and calculate the root mean square difference and Swank factors from simulated and experimental results. The comparison suggests that hybridMANTIS better matches the experimental data as compared to MANTIS, especially at high spatial frequencies and for the thicker screens. hybridMANTIS simulations are much faster than MANTIS with speed-ups up to 5260. hybridMANTIS is a useful tool for improved description and optimization of image acquisition stages in medical imaging systems and for modeling the forward problem in iterative reconstruction algorithms.

    Screening tests of Sand Mantis candidate materials selected for erosion resistance have been completed. The results of this testing identified that over a relatively short period of operation (<1 hour), measurable erosion will occur in each of the candidate zoom tube materials given equal operating exposure. Additionally, this testing has shown that erosion of the rubber discharge hose directly downstream of the vehicle could be expected to limit the service life of the discharge hose. On the basis of these test results, SRNL recommends the following; {lg_bullet} redesign of critical system components (e.g., zoom tube, discharge hose) should be conductedmore » to improve system characteristics relative to erosion and capitalize on the results of this testing, {lg_bullet} continued efforts to deploy the Sand Mantis should include testing to better define and optimize operating parameters, and gain an understanding of system dynamics, {lg_bullet} discontinue wear testing with the selected materials pending redesign of critical system components (1st recommendation) and inclusion of other candidate materials. The final selection of additional candidate materials should be made following design changes, but might include a Stellite alloy or zirconia.« less

  3. Evolution of mantis shrimps (Stomatopoda, Malacostraca) in the light of new Mesozoic fossils

    PubMed Central

    2010-01-01

    Background We describe new specimens of Mesozoic mantis shrimps (Stomatopoda, Malacostraca) that exhibit morphological and developmental information previously unknown. Results Specimens assigned to the taxon Sculda exhibit preserved pleopods, thoracopods including all four raptorial limbs as well as details of antennae and antennulae. The pleopods and the antennulae resemble those of the modern mantis shrimps, but the raptorial limbs are not as differentiated as in the modern species. In some specimens, the first raptorial limb (second thoracopod) is not significantly larger than the similar-sized posterior three pairs (as in extant species), but instead these appendages become progressively smaller along the series. In this respect they resemble certain Palaeozoic stomatopods. Another specimen, most likely belonging to another species, has one pair of large anterior raptorial thoracopods, a median-sized pair and two more pairs of small-sized raptorial appendages and, thus, shows a new, previously unknown type of morphology. A single specimen of Pseudosculda laevis also exhibits the size of the raptorial limbs; they are differentiated as in modern species, one large pair and three small pairs. Furthermore, we report additional larval specimens and show also post-larval changes, e.g., of the tail fan. Conclusions These new data are used to reconsider the phylogeny of Stomatopoda. We still need a strict taxonomical revision of the Mesozoic mantis shrimps, but this first examination already demonstrates the importance of these fossils for understanding mantis shrimp evolution and the interpretation of evolutionary pathways of particular features.

    The computational modeling of medical imaging systems often requires obtaining a large number of simulated images with low statistical uncertainty which translates into prohibitive computing times. We describe a novel hybrid approach for Monte Carlo simulations that maximizes utilization of CPUs and GPUs in modern workstations. We apply the method to the modeling of indirect x-ray detectors using a new and improved version of the code \\scriptsize{{MANTIS}}, an open source software tool used for the Monte Carlo simulations of indirect x-ray imagers. We first describe a GPU implementation of the physics and geometry models in fast\\scriptsize{{DETECT}}2 (the optical transport model) and a serial CPU version of the same code. We discuss its new features like on-the-fly column geometry and columnar crosstalk in relation to the \\scriptsize{{MANTIS}} code, and point out areas where our model provides more flexibility for the modeling of realistic columnar structures in large area detectors. Second, we modify \\scriptsize{{PENELOPE}} (the open source software package that handles the x-ray and electron transport in \\scriptsize{{MANTIS}}) to allow direct output of location and energy deposited during x-ray and electron interactions occurring within the scintillator.

    In these studies a constant ERG response was used as a measure of visual sensitivity to different wavelengths of light. The dark-adapted compound eye of Tenodera sinensis is dominated by a single class of photoreceptors. with a major peak of sensitivity at about 510–520 nm, and with a minor peak of sensitivity in the near-ultraviolet region at about 370 nm. The dark-adapted dorsal ocellus does not contain a homogeneous population of sensory receptors. The sensitivity function of the dark-adapted ocellus to longer wavelength light (yellow and red) is determined by a single receptor with a major peak of sensitivity in the green at 510–520 nm with some sensitivity in the near-ultraviolet. Sensitivity at shorter wavelengths (near-ultraviolet and blue), however, involves the stimulation of both this and a near-ultraviolet-sensitive receptor with a maximum sensitivity at about 370 nm. Anatomically, the sensory cells of the dorsal ocellus of Tenodera were determined histologically to be grouped into two distinct regions, each group making its own separate contribution to the ocellar nerve. This may represent the separation of two different photoreceptor types in the ocellus of the mantis. PMID:5539340

    Purpose: MANTIS is a Monte Carlo code developed for the detailed simulation of columnar CsI scintillator screens in x-ray imaging systems. Validation of this code is needed to provide a reliable and valuable tool for system optimization and accurate reconstructions for a variety of x-ray applications. Whereas previous validation efforts have focused on matching of summary statistics, in this work the authors examine the complete point response function (PRF) of the detector system in addition to relative light output values. Methods: Relative light output values and high-resolution PRFs have been experimentally measured with a custom setup. A corresponding set ofmore » simulated light output values and PRFs have also been produced, where detailed knowledge of the experimental setup and CsI:Tl screen structures are accounted for in the simulations. Four different screens were investigated with different thicknesses, column tilt angles, and substrate types. A quantitative comparison between the experimental and simulated PRFs was performed for four different incidence angles (0 deg., 15 deg., 30 deg., and 45 deg.) and two different x-ray spectra (40 and 70 kVp). The figure of merit (FOM) used measures the normalized differences between the simulated and experimental data averaged over a region of interest. Results: Experimental relative light output values ranged from 1.456 to 1.650 and were in approximate agreement for aluminum substrates, but poor agreement for graphite substrates. The FOMs for all screen types, incidence angles, and energies ranged from 0.1929 to 0.4775. To put these FOMs in context, the same FOM was computed for 2D symmetric Gaussians fit to the same experimental data. These FOMs ranged from 0.2068 to 0.8029. Our analysis demonstrates that MANTIS reproduces experimental PRFs with higher accuracy than a symmetric 2D Gaussian fit to the experimental data in the majority of cases.

    Stable isotope analysis has provided insights into the trophic ecology of a wide diversity of animals. Knowledge about isotopic incorporation rates and isotopic discrimination between the consumer and its diet for different tissue types is essential for interpreting stable isotope data, but these parameters remain understudied in many animal taxa and particularly in aquatic invertebrates. We performed a 292-day diet shift experiment on 92 individuals of the predatory mantis shrimp, Neogonodactylus bredini, to quantify carbon and nitrogen incorporation rates and isotope discrimination factors in muscle and hemolymph tissues. Average isotopic discrimination factors between mantis shrimp muscle and the new diet were 3.0 ± 0.6 ‰ and 0.9 ± 0.3 ‰ for carbon and nitrogen, respectively, which is contrary to what is seen in many other animals (e.g. C and N discrimination is generally 0–1 ‰ and 3–4 ‰, respectively). Surprisingly, the average residence time of nitrogen in hemolymph (28.9 ± 8.3 days) was over 8 times longer than that of carbon (3.4 ± 1.4 days). In muscle, the average residence times of carbon and nitrogen were of the same magnitude (89.3 ± 44.4 and 72.8 ± 18.8 days, respectively). We compared the mantis shrimps’ incorporation rates, along with rates from four other invertebrate taxa from the literature, to those predicted by an allometric equation relating carbon incorporation rate to body mass that was developed for teleost fishes and sharks. The rate of carbon incorporation into muscle was consistent with rates predicted by this equation. Our findings provide new insight into isotopic discrimination factors and incorporation rates in invertebrates with the former showing a different trend than what is commonly observed in other animals.

    This paper presents the mantisGRID project, an interinstitutional initiative from Colombian medical and academic centers aiming to provide medical grid services for Colombia and Latin America. The mantisGRID is a GRID platform, based on open source grid infrastructure that provides the necessary services to access and exchange medical images and associated information following digital imaging and communications in medicine (DICOM) and health level 7 standards. The paper focuses first on the data abstraction architecture, which is achieved via Open Grid Services Architecture Data Access and Integration (OGSA-DAI) services and supported by the Globus Toolkit. The grid currently uses a 30-Mb bandwidth of the Colombian High Technology Academic Network, RENATA, connected to Internet 2. It also includes a discussion on the relational database created to handle the DICOM objects that were represented using Extensible Markup Language Schema documents, as well as other features implemented such as data security, user authentication, and patient confidentiality. Grid performance was tested using the three current operative nodes and the results demonstrated comparable query times between the mantisGRID (OGSA-DAI) and Distributed mySQL databases, especially for a large number of records.

    This article presents and technically describes a new field spectro-goniometer system for the ground-based characterization of the surface reflectance anisotropy under natural illumination conditions developed at the Alfred Wegener Institute (AWI). The spectro-goniometer consists of a Manual Transportable Instrument platform for ground-based Spectro-directional observations (ManTIS), and a hyperspectral sensor system. The presented measurement strategy shows that the AWI ManTIS field spectro-goniometer can deliver high quality hemispherical conical reflectance factor (HCRF) measurements with a pointing accuracy of ±6 cm within the constant observation center. The sampling of a ManTIS hemisphere (up to 30° viewing zenith, 360° viewing azimuth) needs approx. 18 min. The developed data processing chain in combination with the software used for the semi-automatic control provides a reliable method to reduce temporal effects during the measurements. The presented visualization and analysis approaches of the HCRF data of an Arctic low growing vegetation showcase prove the high quality of spectro-goniometer measurements. The patented low-cost and lightweight ManTIS instrument platform can be customized for various research needs and is available for purchase.

    The evolution of the field of biomedical technology has led to the diffusion of an impressive number of medical devices into healthcare institutions. In this environment, Clinical Engineering Departments (CEDs) are expanding their role in healthcare technology management, by changing their structure and introducing quality systems in order to improve their services and monitor the outcomes. In the framework of the national project BIOTECHNET II, a software tool for the management of biomedical technology, named CLE-MANTIS, has been developed, with the aim to assist CEDs in their tasks. CLE-MANTIS functions include the upkeep of an inventory, the support and monitoring of scheduled maintenance, corrective maintenance, vigilance, equipment acquisition and replacement, service contract management and user training. The system offers clinical engineers the possibility to monitor and evaluate the quality and cost-effectiveness of their departments through the monitoring of quality and cost indicators. This paper presents the main features and functions of the system.

    Calcified marine organisms typically experience increased oxidative stress and changes in mineralization in response to ocean acidification and warming conditions. These effects could hinder the potency of animal weapons, such as the mantis shrimp’s raptorial appendage. The mechanical properties of this calcified weapon enable extremely powerful punches to be delivered to prey and aggressors. We examined oxidative stress and exoskeleton structure, mineral content, and mechanical properties of the raptorial appendage and the carapace under long-term ocean acidification and warming conditions. The predatory appendage had significantly higher % Mg under ocean acidification conditions, while oxidative stress levels as well as the % Ca and mechanical properties of the appendage remained unchanged. Thus, mantis shrimp tolerate expanded ranges of pH and temperature without experiencing oxidative stress or functional changes to their weapons. Our findings suggest that these powerful predators will not be hindered under future ocean conditions. PMID:27974830

    2005-01-01

    Background Animal mitochondrial genomes are physically separate from the much larger nuclear genomes and have proven useful both for phylogenetic studies and for understanding genome evolution. Within the phylum Arthropoda the subphylum Crustacea includes over 50,000 named species with immense variation in body plans and habitats, yet only 23 complete mitochondrial genomes are available from this subphylum. Results I describe here the complete mitochondrial genome of the crustacean Squilla mantis (Crustacea: Malacostraca: Stomatopoda). This 15994-nucleotide genome, the first described from a hoplocarid, contains the standard complement of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a non-coding AT-rich region that is found in most other metazoans. The gene order is identical to that considered ancestral for hexapods and crustaceans. The 70% AT base composition is within the range described for other arthropods. A single unusual feature of the genome is a 230 nucleotide non-coding region between a serine transfer RNA and the nad1 gene, which has no apparent function. I also compare gene order, nucleotide composition, and codon usage of the S. mantis genome and eight other malacostracan crustaceans. A translocation of the histidine transfer RNA gene is shared by three taxa in the order Decapoda, infraorder Brachyura; Callinectes sapidus, Portunus trituberculatus and Pseudocarcinus gigas. This translocation may be diagnostic for the Brachyura. For all nine taxa nucleotide composition is biased towards AT-richness, as expected for arthropods, and is within the range reported for other arthropods. Codon usage is biased, and much of this bias is probably due to the skew in nucleotide composition towards AT-richness. Conclusion The mitochondrial genome of Squilla mantis contains one unusual feature, a 230 base pair non-coding region has so far not been described in any other malacostracan. Comparisons with other Malacostraca show that all

    Insectivorous echolocating bats face a formidable array of defenses employed by their airborne prey. One such insect defense is the ultrasound-triggered dive, which is a sudden, rapid drop in altitude, sometimes all the way to the ground. Although many previous studies have investigated the dynamics of such dives and their effect on insect survival rate, there has been little work on how bats may adapt to such an insect defense employed in the middle of pursuit. In this study we investigated how big brown bats (Eptesicus fuscus) adjust their pursuit strategy when flying praying mantises (Parasphendale agrionina) execute evasive, ultrasound-triggered dives. Although the mantis dive occasionally forced the bat to completely abort its chase (25% trials), in a number of cases (75% trials) the bat followed the mantis into the dive. In such cases the bat kept its sonar beam locked onto the target and maneuvered to maintain the same time efficient strategy it adopted during level flight pursuit, though it was ultimately defeated by the dive. This study suggests that although the mantis dive can be effective in evading the bat, it does not always deter the bat from continuing pursuit and, given enough altitude, the bat can potentially capture diving prey using the same flight strategy it employs to intercept prey in level flight.

    2005-09-30

    Before jumping to a landing object, praying mantids determine the distance, using information obtained from retinal image motion resulting from horizontal peering movements. The present study investigates the peering-jump behaviour of Mantis religiosa larvae with regard to jump targets differing in shape and size. The experimental animals were presented with square, triangular and round target objects with visual extensions of 20 degrees and 40 degrees. The cardboard objects, presented against a uniform white background, were solid black or shaded with a gradation from white to black. It was found that larger objects were preferred to smaller ones as jump targets, and that the square and triangle were preferred to the round disk. When two objects were presented, no preference was exhibited between square and triangular objects. However, when three objects were presented, the square was preferred. For targets with a visual angle of 40 degrees, the amplitude and velocity of the horizontal peering movements were greater for the round disk than for the square or triangle. This amplification of the peering movements suggests that weaker motion signals are generated in the case of curved edges. This may help to account for the preference for the square and triangle as jump targets.

    Dictyoptera which consist of cockroaches, termites, and praying mantids are among the oldest pterygote insects known. Whereas the localization and sequences of neuropeptides from a number of cockroaches are very well known, nearly nothing is known about the neuropeptides typical of praying mantids. In this study, the neuroanatomy of the median neuroendocrine system in the abdominal ventral nerve cord and the sequences of the CAPA-peptides which are expressed in the respective neuroendocrine cells were analyzed. Altogether, 40 species belonging to different families of Mantodea were included. In contrast to cockroaches, the mantids mostly express two CAPA-periviscerokinins (PVKs), only in Mantis religiosa a third PVK was identified. These PVKs are sequence-related to the PVKs of basal cockroaches (Polyphagidae). In a group of closely related Mantodea (Paramantinae), extended forms of PVK-2 were observed. As shown, these forms are possibly the result of substitutions in the N-terminal cleavage sites of the respective PVKs. No trace of a CAPA-pyrokinin was found in any of the praying mantids.

    Animal invasions can be devastating for native species. Behavioral variation is known to influence animal invasions, yet comparatively less is known about how behavioral variation influences invasive-native species interactions. Here we examined how the mean and variance surrounding several behavioral traits in two sympatric species of praying mantis differ and how these behavioral types translate to actual prey capture success using the introduced European mantis, Mantis religiosa, and the native bordered mantis, Stagmomantis limbata. We assayed time spent in the open (risk proneness), response towards a novel prey, and voracity within a population of M. religiosa and S. limbata. We found that the native and invasive mantids displayed no differences in their average behavioral tendencies. The native exhibited significant levels of repeatability in voracity while the invasive did not. The lack of repeatability in the invasive appears to be driven by lower levels of among-individual variation in voracity. This may have evolutionary consequences for native S. limbata if it results in strong selection in native levels of mean and among-individual variation. Significant levels of among-individual differences were found in other behaviors (response to a novel prey and risk proneness) across species, suggesting less selection on invasive behavioral variation in these traits. Risk proneness and response towards a novel prey also formed a behavioral syndrome across species, yet neither behavior was correlated with voracity in either species. Our results illustrate the need to examine the ecological effects of behavioral variation of both invasive and native species to determine how that might impact invasive-native interactions.

    A key component to testing geodynamic hypotheses resulting from the 3D mantle convection simulations is the ability to easily translate the predicted physiochemical state to the model space relevant for an independent geophysical observation, such as earth's seismic, geodetic or electromagnetic response. In this contribution a new parallel code for simulating low-frequency, global-scale electromagnetic induction phenomena is introduced that has the same Earth discretization as the popular CitcomS mantle convection code. Hence, projection of the CitcomS model into the model space of electrical conductivity is greatly simplified, and focuses solely on the node-to-node, physics-based relationship between these Earth parameters without the need for "upscaling", "downscaling", averaging or harmonizing with some other model basis such as spherical harmonics. Preliminary performance tests of the MANTIS code on shared and distributed memory parallel compute platforms shows favorable scaling (>70% efficiency) for up to 500 processors. As with CitcomS, an OpenDX visualization widget (VISMAN) is also provided for 3D rendering and interactive interrogation of model results. Details of the MANTIS code will be briefly discussed here, focusing on compatibility with CitcomS modeling, as will be preliminary results in which the electromagnetic response of a CitcomS model is evaluated.

    Many animals are considered to be specialists because they have feeding structures that are fine-tuned for consuming specific prey. For example, "smasher" mantis shrimp have highly specialized predatory appendages that generate forceful strikes to break apart hard-shelled prey. Anecdotal observations suggest, however, that the diet of smashers may include soft-bodied prey as well. Our goal was to examine the diet breadth of the smasher mantis shrimp, Neogonodactylus bredini, to determine whether it has a narrow diet of hard-shelled prey. We combined studies of prey abundance, feeding behavior, and stable isotope analyses of diet in both seagrass and coral rubble to determine if N. bredini's diet was consistent across different habitat types. The abundances of hard-shelled and soft-bodied prey varied between habitats. In feeding experiments, N. bredini consumed both prey types. N. bredini consumed a range of different prey in the field as well and, unexpectedly, the stable isotope analysis demonstrated that soft-bodied prey comprised a large proportion (29-53 %) of the diet in both habitats. Using a Bayesian mixing model framework (MixSIAR), we found that this result held even when we used uninformative, or generalist, priors and informative priors reflecting a specialist diet on hard-shelled prey and prey abundances in the field. Thus, contrary to expectation, the specialized feeding morphology of N. bredini corresponds to a broad diet of both hard-shelled and soft-bodied prey. Using multiple lines of study to describe the natural diets of other presumed specialists may demonstrate that specialized morphology often broadens rather than narrows diet breadth.

The following new nomenclatural procedures are introduced: Musoniella margharethae Battiston and Picciau, 2008 is transferred to Musonia as Musonia margharethae (Battiston and Picciau, 2008) (comb. n.), and Phyllovates brevicollis Orofino, Ippolito and Lombardo, 2006 is considered a new synonym (syn. n.) of Pseudovates peruviana (Rehn, 1911). A new genus, Piscomantis gen. n., is established to accommodate Galapagia peruana Beier, 1935, which is now referred to as Piscomantis peruana (Beier, 1935) (comb. n.). Ten species are removed from the Peruvian mantis fauna and two nomina nuda are proposed. An overview of the biogeography and ecology of Peruvian praying mantises is presented.

    This is one of a series of maps that describe the geology and related natural resources of the Manti 30 x 60 minute quadrangle. Streamflow records used to compile this map were collected by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights, and the Utah Department of Transportation. The principal runoff-producing areas shown on the map were delineated from a work map (scale 1:250,000) compiled to estimate water yields in Utah (Bagley and others, 1964). Sources of information about recorded floods resulting from cloudbursts included Woolley (1946) and Butler and Marsell (1972); sources of information about the chemical quality of streamflow included Hahl and Cabell (1965) and Mundorff and Thompson (1982).

    Predators can reduce bee pollination and plant fitness through successful predation and non-consumptive effects. In honey bees, evidence of predation or a direct attack can decrease recruitment dancing and thereby magnify the effects of individual predation attempts at a colony level. However, actual predation attempts and successes are relatively rare. It was not known if a far more common event, just detection of a predator, could inhibit recruitment. We began by testing honey bees' avoidance of the praying mantis (Tenodera sinensis). Larger predators (later mantis instars, ≥4.5 cm in body length) elicited significantly more avoidance (1.3 fold) than smaller mantis instars. Larger instars also attempted to capture honey bees significantly more often than did smaller instars. Foragers could detect and avoid mantises based upon mantis odor (74% of bees avoided an odor extract) or visual appearance (67% avoided a mantis model). Finally, foragers decreased recruitment dancing by 1.8 fold for a food source with a live adult mantis, even when they were not attacked. This reduction in recruitment dancing, elicited by predator presence alone, expands our understanding of predator non-consumptive effects and of cascading ecosystem effects for plants served by an important generalist pollinator.

  8. A review of the research on Canary Islands praying mantises (Mantodea).

    For many years researchers studying the fauna of the Canary Islands have only sparsely treated the charismatic insect order of praying mantises (Mantodea). By studying the known literature it becomes obvious that there are several inconsistencies regarding mantodean taxonomy as well as the number of actual species and their distribution within the archipelago. In the present contribution, the literature treating the Canary Island Mantodea fauna is thoroughly reviewed, and the distribution of the ten known Mantodea species is presented with additional comments on the taxonomic problems. The taxonomy and distribution of the Canary Island Amelinae has been causing some confusion in the literature and is therefore discussed for a better understanding of the composition of this group. So far, seven species of Amelinae (two species of Ameles Burmeister and five species of Pseudoyersinia Kirby) are recognized for the Canary Islands. A careful survey of the taxonomic literature indicates that there is a substantial degree of variability in this group, which may have led to frequent misidentifications. This is reflected by the inconsistent literature data on the distribution of several Pseudoyersinia species within the archipelago. A crucial amendment and clarification is provided regarding the date of description (1838) of Ameles gracilis (Brullé) and Ameles limbata (Brullé) as it varies in the literature. Nomenclatural changes regarding the homonymy of Mantis limbata Brullé and Mantis limbata Hahn, previously proposed by Koçak & Kemal (2008), are rejected and discussed in detail. One of the Mantodea species, Empusa pennata (Thunberg), is frequently mentioned in the literature to be present on the Canary Islands, but after carefully reviewing the literature data it is evident that this species has never actually been found on any of the islands. The aim of this publication is to lay a basis for future research on the Mantodea fauna of the Canary Islands, their

    This study is aimed at assessing the effects of multiple stressors (thermal shock, fishing capture, and exposure to air) on the benthic stomatopod Squilla mantis, a burrowing crustacean quite widespread in the Mediterranean Sea. Laboratory analyses were carried out to explore the physiological impairment onset over time, based on emersion and thermal shocks, on farmed individuals. Parallel field-based studies were carried out to also investigate the role of fishing (i.e., otter trawling) in inducing physiological imbalance in different seasonal conditions. The dynamics of physiological recovery from physiological disruption were also studied. Physiological stress was assessed by analysing hemolymph metabolites (L-Lactate, D-glucose, ammonia, and H+), as well as glycogen concentration in muscle tissues. The experiments were carried out according to a factorial scheme considering the three factors (thermal shock, fishing capture, and exposure to air) at two fixed levels in order to explore possible synergistic, additive, or antagonistic effects among factors. Additive effects on physiological parameters were mainly detected when the three factors interacted together while synergistic effects were found as effect of the combination of two factors. This finding highlights that the physiological adaptive and maladaptive processes induced by the stressors result in a dynamic response that may encounter physiological limits when high stress levels are sustained. Thus, a further increase in the physiological parameters due to synergies cannot be reached. Moreover, when critical limits are encountered, mortality occurs and physiological parameters reflect the response of the last survivors. In the light of our mortality studies, thermal shock and exposure to air have the main effect on the survival of S. mantis only on trawled individuals, while lab-farmed individuals did not show any mortality during exposure to air until after 2 hours.

    After the Aznalcóllar mining spill (25th April 1998), considerable social concern arose amongst the inhabitants of the SW Iberian Peninsula concerning the consumption of local seafood. Squilla mantis was collected in four regions of the Gulf of Cádiz with a dual objective: to analyze the heavy metal levels for human consumption and as part of biomonitoring program. Heavy metal concentrations (Fe, Mn, Zn, Cu, Cd and Pb) were analyzed in soft tissues and cuticle. The highest values were found in the soft tissues for zinc, copper and cadmium and in the cuticle for iron, manganese and lead. The mean copper concentration in the soft tissue, corresponding to the edible part, was 27.1 microg x g(-1) wet weight. Approximately 80% of stations showed values higher than 20 microg x g(-1) wet weight of copper, the Spanish legal limit for the concentration of this metal in the crustacean for human consumption. For Zn and Cu no significant differences were found between regions, probably related with the capacity for regulation of S. mantis. The highest values found for copper in the Gulf of Cádiz compared to other areas is likely to be related with contamination from terrestrial mining activities (copper and pyrites) in the region, dating back to the times of Tartessians and Romans, rather than the effects of mining spill which was shown not to create any significant increases in heavy metal concentrations of organisms of the Guadalquivir River or the adjacent coastal area.

    Past and recent climatic changes induced shifts in species ranges. Mantis religiosa has also expanded its range across Germany within the past decades. To determine the ancestry of German M. religiosa we sequenced four mitochondrial genes (COI, COII, Cyt b, ND4) of European M. religiosa populations. We found an east, central and west European lineage of M. religiosa. These distinct lineages are consistent with genetic isolation by distance during glacial periods, and the re-colonization of northern parts of Europe by species from different refugia. Within Germany, we found haplotypes clustering to the central and west European lineage suggesting that M. religiosa immigrated from two directions into Germany. Mismatch distributions, and negative Tajima's D and Fu's Fs values indicate a current range expansion of the central and west European lineage. We hypothesise that ongoing global warming which increases the availability of thermally favourable areas in Germany for M. religiosa adds to its current range expansion. In conclusion, M. religiosa colonized Germany via two directions: west German populations descended from French populations and east German populations from Czech populations.

    Madeirasquilla tuerkayi is described as a new genus and species of the nannosquillid mantis shrimps (Stomatopoda) based on a single specimen collected from Madeira, eastern Atlantic. That specimen is remarkable by a combination of the following morphological characters: rostral plate with three sharp anterior projections; antennal protopod with two mesial and one ventral papillae; cornea subglobular; raptorial claw dactylus with 11 or 12 teeth, and with acute proximal tooth on outer margin; pleonite 6 with strong posterolateral spine and two posteriorly directed sternal spines; telson bearing smooth shield-like dorsal prominence with acute median spine posteriorly; four pairs of fixed primary teeth posteriorly on the telson; outer primary spine of uropodal protopod longer than inner primary spine. The separate position of the new genus is supported also by molecular comparison. A key to the genera of the family Nannosquillidae is proposed.

  15. Sexual cannibalism increases male material investment in offspring: quantifying terminal reproductive effort in a praying mantis

    2016-01-01

    Models of the evolution of sexual cannibalism argue that males may offset the cost of cannibalism if components of the male body are directly allocated to the eggs that they fertilize. We tested this idea in the praying mantid Tenodera sinensis. Males and females were fed differently radiolabelled crickets and allowed to mate. Half of the pairs progressed to sexual cannibalism and we prevented cannibalism in the other half. We assess the relative allocation of both male-derived somatic materials and ejaculate materials into the eggs and soma of the female. Our results show that male somatic investment contributes to production of offspring. The eggs and reproductive tissues of cannibalistic females contained significantly more male-derived amino acids than those of non-cannibalistic females, and there was an increase in the number of eggs produced subsequent to sexual cannibalism. Sexual cannibalism thus increases male material investment in offspring. We also show that males provide substantial investment via the ejaculate, with males passing about 25% of their radiolabelled amino acids to females via the ejaculate even in the absence of cannibalism.

    The Multispectral Advanced Narrowband Tokamak Imaging System (MANTIS) is proposed to resolve the steep temperature and density gradients in the scrape-off layer of tokamaks in real-time. The initial design is to deliver two-dimensional distributions of key plasma parameters of the TCV tokamak to a real-time control system in order to enable novel control strategies, while providing new insights into power exhaust physics in the full offline analysis. This paper presents the conceptual system design, the mechanical and optical design of a prototype that was built to assess the optical performance, and the results of the first proof-of-principle tests of the prototype. These demonstrate a central resolving power of 50-46 line pairs per millimeter (CTF50) in the first four channels. For the additional channels, the sharpness is a factor two worse for the odd channels (likely affected by sub-optimal alignment), while the even channels continue the trend observed for the first four channels of 3% degradation per channel. This is explained by the self-cancellation of off-axis aberrations, which is an attractive property of the chosen optical design. The results show that at least a 10-channel real-time multispectral imaging system is feasible.

    We investigated effects of severe hypoxia (dissolved oxygen <1 ml l(-1)) on recruitment of mantis shrimp Oratosquilla oratoria in Tokyo Bay. Ten-year field surveys were conducted to examine quantitative relationships in annual mean densities of larvae and juveniles, and spatial distribution of juveniles and severe hypoxia. There was no significant correlation between annual mean densities of larvae and juveniles, suggesting that mortality during larval or juvenile stages varies among years, which might have regulated abundance of young-of-the-year juveniles. Juvenile density was low in the severely hypoxic area, implying that hypoxia could affect survivals and spatial distribution of juveniles. Meanwhile, there are yearly fluctuations in juvenile density in normoxic areas of both northern and southern part of the bay. This evidence suggests that abundance of post-settled juveniles might have been determined by not only effects of hypoxia, but also other factors influencing mortality during the early life stages.

    Caterpillars of the monarch butterfly, Danaus plexippus, feed on milkweed plants, Asclepias spp. (Apocynaceae), and sequester their toxic cardenolides aimed at deterring predators. Nevertheless, Chinese praying mantids, Tenodera sinensis, consume these caterpillars after removing the midgut ("gutting") including its plant content. In the present study, monarch caterpillars raised on A. curassavica, and those of the death's-head hawkmoth, Acherontia atropos, raised on Atropa belladonna containing atropine, were fed to mantids, Hierodula membranacea, which removed the gut of both species discarding about 59% of cardenolides and more than 90% of atropine, respectively. The ingestion of these compounds produced no apparent ill effects in the mantids and both were excreted with faeces. On the other hand, when mantids were fed with larvae of two moth species, Amata mogadorensis and Brahmaea certia, raised on non-poisonous host plants, the mantids showed the same gutting behaviour, thereby discarding indigestible plant material. As polar compounds, e.g. cardenolides and atropine, are not absorbed from the mantids midgut and do not pass the gut membrane, this enables the mantids to feed on toxic prey.

  1. Habitat Preference of German Mantis religiosa Populations (Mantodea: Mantidae) and Implications for Conservation.

    In Germany, the thermophilic European mantid (Mantis religiosa L.) is endangered. Here, we study habitat requirements during its life, and discuss the applicability of the two conservation measures grazing and mowing to this insect species. At two study sites in south-western Germany, which were each subject to one of these measures, we recorded structural and climatic conditions within different microhabitats. We also conducted capture-mark-recapture studies for adult M. religiosa, and mapped adult roosting, oothecae deposition, egg hatching, and imaginal molting in microhabitats over two vegetation periods. In order to assess microhabitat preference of M. religiosa during its life, and identify climatic conditions driving preferences, we applied the Lille habitat preference index and conducted logistic regression analysis for life phases. Our results suggest that temperature is important for egg and nymph development. For egg deposition, females preferred solid substrates with high heat-storing capacities, as those attenuate the negative influence of cold weather periods on egg development. Being ambush predators, males and females preferred roosting sites with sufficient shelter and high prey abundance. Contrary to our expectation, the conservation measures reduced adult population sizes, and presumably reproduction rates. We thus suggest that mowing during the adult phase should reduce vegetation height to a moderate level to keep prey abundance high. Mowing with a clearing saw or grazing over a short period in small fenced areas should be preferred over prolonged grazing, as grazers collaterally stamp down the vegetation. Grazers indirectly reduce prey availability by deteriorating prevailing microclimatic conditions. © The Authors 2016.

    Praying mantis is one of the most efficient predators in insect world, which has a pair of powerful tools, two sharp and strong forelegs. Its femur and tibia are both armed with a double row of strong spines along their posterior edges which can firmly grasp the prey, when the femur and tibia fold on each other in capturing. These spines are so sharp that they can easily and quickly cut into the prey. The geometrical characteristic of the praying mantis's foreleg, especially its tibia, has important reference value for the design of agricultural soil-cutting tools. Learning from the profile and arrangement of these spines, cutting blades with tooth profile were designed in this work. Two different sizes of tooth structure and arrangement were utilized in the design on the cutting edge. A conventional smooth-edge blade was used to compare with the bionic serrate-edge blades. To compare the working efficiency of conventional blade and bionic blades, 3D finite element simulation analysis and experimental measurement were operated in present work. Both the simulation and experimental results indicated that the bionic serrate-edge blades showed better performance in cutting efficiency.

    Overlap in the form of sexual signals such as pheromones raises the possibility of reproductive interference by invasive species on similar, yet naive native species. Here, we test the potential for reproductive interference through heterospecific mate attraction and subsequent predation of males by females of a sexually cannibalistic invasive praying mantis. Miomantis caffra is invasive in New Zealand, where it is widely considered to be displacing the only native mantis species, Orthodera novaezealandiae, and yet mechanisms behind this displacement are unknown. We demonstrate that native males are more attracted to the chemical cues of introduced females than those of conspecific females. Heterospecific pairings also resulted in a high degree of mortality for native males. This provides evidence for a mechanism behind displacement that has until now been undetected and highlights the potential for reproductive interference to greatly influence the impact of an invasive species.

    We present the description of a new genus and new species of praying mantis, Hondurantemna chespiritoi gen. n. & sp. n. This species of cryptic mantis, collected in National parks in Mexico and Honduras, remained unknown despite its considerable body size. Based on a phylogenetic analysis with molecular data and traditional morphological analysis, we place this new genus within Antemninae, a monotypic Mantidae subfamily. We update the subfamily concept for Antemninae and provide a key to the two genera. We describe the external morphology of immatures and adults of the new species as well as the genital complexes of both sexes and the ootheca of Antemna rapax . The observed morphological changes between immature and adult females suggests that the selection for an alternate strategy for crypsis is a response to size increase of the abdomen during development. Immatures exploit a stick/branch habitat based on their morphological appearance while adult females appear as a leaf to disguise the profile of the body.

    Purpose: Monte Carlo simulations play a vital role in the understanding of the fundamental limitations, design, and optimization of existing and emerging medical imaging systems. Efforts in this area have resulted in the development of a wide variety of open-source software packages. One such package, hybridMANTIS, uses a novel hybrid concept to model indirect scintillator detectors by balancing the computational load using dual CPU and graphics processing unit (GPU) processors, obtaining computational efficiency with reasonable accuracy. In this work, the authors describe two open-source visualization interfaces, webMANTIS and visualMANTIS to facilitate the setup of computational experiments via hybridMANTIS. Methods: Themore » visualization tools visualMANTIS and webMANTIS enable the user to control simulation properties through a user interface. In the case of webMANTIS, control via a web browser allows access through mobile devices such as smartphones or tablets. webMANTIS acts as a server back-end and communicates with an NVIDIA GPU computing cluster that can support multiuser environments where users can execute different experiments in parallel. Results: The output consists of point response and pulse-height spectrum, and optical transport statistics generated by hybridMANTIS. The users can download the output images and statistics through a zip file for future reference. In addition, webMANTIS provides a visualization window that displays a few selected optical photon path as they get transported through the detector columns and allows the user to trace the history of the optical photons. Conclusions: The visualization tools visualMANTIS and webMANTIS provide features such as on the fly generation of pulse-height spectra and response functions for microcolumnar x-ray imagers while allowing users to save simulation parameters and results from prior experiments. The graphical interfaces simplify the simulation setup and allow the user to go directly from

    The mantis shrimp Oratosquilla oratoria is an ecologically and economically important species in the Western Pacific. In present study, the population genetic structure of Oratosquilla oratoria from the Yellow Sea and East China Sea was examined with mitochondrial DNA control region sequences. In total, 394 samples were collected from 18 locations and 102 haplotypes were obtained. For the Yellow Sea, the overall nucleotide diversity and haplotype diversity were 0.006 9 and 0.946 8, respectively; while across all the East China Sea locations, the overall nucleotide diversity and haplotype diversity were 0.027 94 and 0.979 0, respectively. The results of AMOVA and pairwise F ST (0.145 2, P <0.001) revealed moderate differentiation between the Yellow Sea and East China Sea populations of O. oratoria. However, neither the neighbor-joining tree nor haplotype network showed clades with geographic pattern, which indicated considerable gene flow was existed between the Yellow Sea and East China Sea, and supporting the high larval dispersal ability in this species. Mismatch distribution analysis and neutrality tests suggested that O. oratoria has undergone population expansion event, and the Pleistocene glacial cycles might have an impact on the historical demography of O. oratoria. The genetic information obtained in this study can provide useful information for sustainable improvements for capture fisheries management strategies.

    Insect mitochondrial genomes (mitogenomes) contain a conserved set of 37 genes for an extensive diversity of lineages. Previously reported dictyopteran mitogenomes share this conserved mitochondrial gene arrangement, although surprisingly little is known about the mitogenome of Mantodea. We sequenced eight mantodean mitogenomes including the first representatives of two families: Hymenopodidae and Liturgusidae. Only two of these genomes retain the typical insect gene arrangement. In three Liturgusidae species, the trnM genes have translocated. Four species of mantis (Creobroter gemmata, Mantis religiosa, Statilia sp., and Theopompa sp.-HN) have multiple identical tandem duplication of trnR, and Statilia sp. additionally includes five extra duplicate trnW. These extra trnR and trnW in Statilia sp. are erratically arranged and form another novel gene order. Interestingly, the extra trnW is converted from trnR by the process of point mutation at anticodon, which is the first case of tRNA reassignment for an insect. Furthermore, no significant differences were observed amongst mantodean mitogenomes with variable copies of tRNA according to comparative analysis of codon usage. Combined with phylogenetic analysis, the characteristics of tRNA only possess limited phylogenetic information in this research. Nevertheless, these features of gene rearrangement, duplication, and reassignment provide valuable information toward understanding mitogenome evolution in insects.

Four species of mantis (Creobroter gemmata, Mantis religiosa, Statilia sp., and Theopompa sp.-HN) have multiple identical tandem duplication of trnR, and Statilia sp. additionally includes five extra duplicate trnW. These extra trnR and trnW in Statilia sp. are erratically arranged and form another novel gene order. Interestingly, the extra trnW is converted from trnR by the process of point mutation at anticodon, which is the first case of tRNA reassignment for an insect. Furthermore, no significant differences were observed amongst mantodean mitogenomes with variable copies of tRNA according to comparative analysis of codon usage. Combined with phylogenetic analysis, the characteristics of tRNA only possess limited phylogenetic information in this research. Nevertheless, these features of gene rearrangement, duplication, and reassignment provide valuable information toward understanding mitogenome evolution in insects. PMID:27157299

    The butterfly fauna of the Southern Transural region began mainly through the migration of insects from the Urals and Kazakhstan, since the end of the Cretaceous Period to the end of Paleogen, the Transural region was covered by an epiplatform sea. As this sea was retreating, the first regions of dry land appeared, which had boundaries with Kazakhstan and the Urals. They were the first to be populated by Lepidoptera. During the Pleocene and then after the Pleistocene cooling events, insects settled generally along the valley of the Tobol River and the Turgai depression, because these territories belong to intrazonal elements. At the present time, the greatest species diversity among insects in the southern Transural area is observed specifically in the Turgai depression and in areas directly adjacent to it. This territory is mainly occupied by populations unique to the Transural regions and belonging to the following species: Mantis religiosa (praying mantis), Saga pedo, Parnassius apollo (apollo), Neolycaena rhymnus, Hyponephele lupina (oriental meadow brown), Chazara persephone (dark rockbrown), Epicallia villica (cream-spot tiger), etc.

    Characterization of sex chromosomes in males of Mantis religiosa L. (2n = 24 + X1X2Y) was carried out by C-banding, silver staining and fluorescence in situ hybridization. They are meta- or submetacentric, their arms being designated as X1L, X1R, X2R, X2L, YL and YR. Meiotic behaviour of the sex trivalent was examined through the analysis of synaptonemal complexes (SCs), prometaphase I (metaphase I) and metaphase II nuclei. On the basis of the SC analysis, chromosomal length measurements at mitosis and prometaphase I and data from several orthopteran species, it is proposed that the breakpoints of the reciprocal translocation that originated this complex sex-determining mechanism were close to the centromeres of the X and the largest autosome, and that the asynapsed X1L and X2R regions observed in the sex trivalent at pachytene represent the original X chromosome. The X centromere being probably that of the X2 element because it lacks a partner in the SC pachytene trivalent. The relationship among synaptic pattern, chiasma localization and balanced segregation of the sex trivalent is also discussed.

    Growth and reproduction of the Japanese mantis shrimp, Oratosquilla oratoria, were investigated in the Tongyeong, Korea from July 2014 to August 2015. A total of 2,621 samples (1,380 females and 1,241 males) were collected during the study period. Females were observed more frequently than males. The mean body length (BL) was 128.5 ± 0.38 mm in females and 126.9 ± 0.42 mm in males. The mean body weight (BW) was 31.2 ± 0.28 g in females and 31.1 ± 0.32 g in males. There was a significant difference in the length-frequency distribution between females and males. The relationship between BL and BW was lnBW = 2.85 × lnBL - 10.43 for females and lnBW = 2.87 × lnBL -10.52 for males. The gonadosomatic index (GSI) varied on a monthly basis. The GSI reached a maximum in May and a minimum in November. The highest values of the GSI coincided with the spawning period of O. oratoria. Larger individuals of O. oratoria have their spawning season earlier than smaller ones. The size at sexual maturity of females was estimated as 96.5 mm. The Von Bertalanffy growth function parameters were BL∞ = 184.5 mm, K = 0.72 year-1, C = 0.36 and WP = 0.45 for females and BL∞ = 183.75 mm, K = 0.82 year-1, C = 0.38 and WP = 0.22 for males. The growth of males was slightly faster than females. The present study will help with the fisheries management of O. oratoria based on ecological parameters.

    Current surgical robots are controlled by a mechanical master located away from the patient, tracking surgeon's hands by wire and pulleys or mechanical linkage. Contactless hand tracking for surgical robot control is an attractive alternative, because it can be executed with minimal footprint at the patient's bedside without impairing sterility, while eliminating current disassociation between surgeon and patient. We compared technical and technologic feasibility of contactless hand tracking to the current clinical standard master controllers. A hand-tracking system (Kinect™-based 3Gear), a wire-based mechanical master (Mantis Duo), and a clinical mechanical linkage master (da Vinci) were evaluated for technical parameters with strong clinical relevance: system latency, static noise, robot slave tremor, and controller range. Five experienced surgeons performed a skill comparison study, evaluating the three different master controllers for efficiency and accuracy in peg transfer and pointing tasks. da Vinci had the lowest latency of 89 ms, followed by Mantis with 374 ms and 3Gear with 576 ms. Mantis and da Vinci produced zero static error. 3Gear produced average static error of 0.49 mm. The tremor of the robot used by the 3Gear and Mantis system had a radius of 1.7 mm compared with 0.5 mm for da Vinci. The three master controllers all had similar range. The surgeons took 1.98 times longer to complete the peg transfer task with the 3Gear system compared with Mantis, and 2.72 times longer with Mantis compared with da Vinci (p value 2.1e-9). For the pointer task, surgeons were most accurate with da Vinci with average error of 0.72 mm compared with Mantis's 1.61 mm and 3Gear's 2.41 mm (p value 0.00078). Contactless hand-tracking technology as a surgical master can execute simple surgical tasks. Whereas traditional master controllers outperformed, given that contactless hand-tracking is a first-generation technology, clinical potential is promising and could

    The mantis shrimp Oratosquilla oratoria is a widely distributed, commercially important crustacean species. Although its conservation and the development of successful artificial breeding technologies have recently received considerable attention, there are currently no available data regarding the molecular mechanisms in controlling reproduction. In this study, we performed transcriptome sequencing of the testis, ovary, female and male eyestalks and the androgenic gland of O. oratoria, and compared the expression pattern of transcripts from the testis and ovary libraries to identify genes involved in gonadal development. A total of 147,130,937 clean reads were retrieved after removing the adapters in reads and filtering out low-quality data. All the reads were assembled into 94,990 unigenes (23,133 in testis and ovary) with an average length of 783 base pairs (bp) and N50 of 1502 bp. A search of all-unigenes against COG, GO, KEGG, KOG, Pfam, Swiss-Prot and Nr databases resulted in a total of 19,404 annotated unigenes. Comparison of the sequences in the ovary and testis libraries revealed that 1188 unigenes were up-regulated in the ovary and 2732 were up-regulated in the testis. Twenty ovary-up-regulated and 21 testis-up-regulated unigenes were confirmed by quantitative real-time PCR. Additionally, 13,437 simple sequence repeats (SSRs) and 275,799 putative single nucleotide polymorphisms (SNPs) were identified. The important functional genes and pathways identified here provide a valuable dataset for understanding the molecular mechanisms controlling gonad development in O. oratoria, and the numerous (13,437 SSRs and 275,799 SNPs) molecular markers obtained here will provide fundamental basis for functional genomic and population genetic studies of O. oratoria.

    Both market research and literature reports both found that the ootheca of mantodea was all used as medicine. However, Chinese Pharmacopoeia only records the ootheca of three mantis species. The clinical use of ootheca unrecorded in Chinese Pharmacopoeia, will pose potential risks to drug safety. It's urgent to identify the origin of Mantidis Oötheca. The current researches about original animal in Mantidis Oötheca are based on morphology and unanimous. DNA barcoding fill gaps of the traditional morphological identification, which is widely used in animal classification studies. This study first use DNA barcoding to analyze genetic distance among different Mantidis Oötheca types, align COI sequences between mantis and Mantidis Oötheca and construct the phylogeny tree. The result confirmed that Tenodera sinensis and Hierodula patellifera were the origin insects of Tuanpiaoxiao and Heipiaoxiao, respectively, and Statilia maculate and Mantis religiosa were the origin insects of Changpiaoxiao.

    Hand-held 3D scanning systems are increasingly available on the market from several system manufacturers. These systems are deployed for 3D recording of objects with different size in diverse applications, such as industrial reverse engineering, and documentation of museum exhibits etc. Typical measurement distances range from 0.5 m to 4.5 m. Although they are often easy-to-use, the geometric performance of these systems, especially the precision and accuracy, are not well known to many users. First geometrical investigations of a variety of diverse hand-held 3D scanning systems were already carried out by the Photogrammetry & Laser Scanning Lab of the HafenCity University Hamburg (HCU Hamburg) in cooperation with two other universities in 2016. To obtain more information about the accuracy behaviour of the latest generation of hand-held 3D scanning systems, HCU Hamburg conducted further comparative geometrical investigations using structured light systems with speckle pattern (Artec Spider, Mantis Vision PocketScan 3D, Mantis Vision F5-SR, Mantis Vision F5-B, and Mantis Vision F6), and photogrammetric systems (Creaform HandySCAN 700 and Shining FreeScan X7). In the framework of these comparative investigations geometrically stable reference bodies were used. The appropriate reference data was acquired by measurements with two structured light projection systems (AICON smartSCAN and GOM ATOS I 2M). The comprehensive test results of the different test scenarios are presented and critically discussed in this contribution.

    India has an immense faunal, floral, as well as cultural diversity with many ethnic communities who are primarily dependent on the traditional medicinal system for their primary health care. Documentation and evaluation of this indigenous remedial knowledge may be helpful to establish new drugs for human health. The present study is intended to look into different zootherapeutic medicinal uses in the traditional health care system among the native inhabitants adjacent to the Gibbon Wildlife Sanctuary, Assam, India. Field survey was carried out from March 2015 to August 2015 by personal interviews through semi-structured questionnaires. In some cases where participants were uncomfortable with the questionnaires, informal interviews and open group discussions were conducted with a total of 62 indigenous respondents (43 male and 19 female) who provided the information regarding various medicinal uses of animals and their products (local name of animal, mode of preparation, application etc). The study recorded a total of 44 different species, 44 genera and 36 families of animals which are used for the treatment of 40 different ailments. Insects occupied the highest uses (30.9%), followed by mammals (23.8%), fishes (16.7%), reptiles (11.9%), amphibians (7.1%), annelids (4.8%) and gastropods (4.8%). Further, some zootherapeutic animals i.e. cockroach (Periplaneta americana), praying mantis (Mantis religiosa) and earthworms (Metaphire houletti, Pheretima posthum) are used for the treatment of asthma, otorrhoea and cancer respectively. The findings suggest that the traditional zootherapeutic remedial measures followed by the native people adjacent to Gibbon Wildlife Sanctuary plays an important role in their primary health care. The documentation of this indigenous knowledge on animal based medicines should be very helpful in the formulation of strategies for sustainable management and conservation of bio-resources as well as providing potential for the novel drugs

    2017-01-01

    Mushroom bodies are the iconic learning and memory centers of insects. No previously described crustacean possesses a mushroom body as defined by strict morphological criteria although crustacean centers called hemiellipsoid bodies, which serve functions in sensory integration, have been viewed as evolutionarily convergent with mushroom bodies. Here, using key identifiers to characterize neural arrangements, we demonstrate insect-like mushroom bodies in stomatopod crustaceans (mantis shrimps). More than any other crustacean taxon, mantis shrimps display sophisticated behaviors relating to predation, spatial memory, and visual recognition comparable to those of insects. However, neuroanatomy-based cladistics suggesting close phylogenetic proximity of insects and stomatopod crustaceans conflicts with genomic evidence showing hexapods closely related to simple crustaceans called remipedes. We discuss whether corresponding anatomical phenotypes described here reflect the cerebral morphology of a common ancestor of Pancrustacea or an extraordinary example of convergent evolution.

    Gaze stabilization is an almost ubiquitous animal behaviour, one that is required to see the world clearly and without blur. Stomatopods, however, only fix their eyes on scenes or objects of interest occasionally. Almost uniquely among animals they explore their visual environment with a series pitch, yaw and torsional (roll) rotations of their eyes, where each eye may also move largely independently of the other. In this work, we demonstrate that the torsional rotations are used to actively enhance their ability to see the polarization of light. Both Gonodactylus smithii and Odontodactylus scyllarus rotate their eyes to align particular photoreceptors relative to the angle of polarization of a linearly polarized visual stimulus, thereby maximizing the polarization contrast between an object of interest and its background. This is the first documented example of any animal displaying dynamic polarization vision, in which the polarization information is actively maximized through rotational eye movements. PMID:27401817

    To circumvent the limits of muscle, ultrafast movements achieve high power through the use of springs and latches. The time scale of these movements is too short for control through typical neuromuscular mechanisms, thus ultrafast movements are either invariant or controlled prior to movement. We tested whether mantis shrimp (Stomatopoda: Neogonodactylus bredini) vary their ultrafast smashing strikes and, if so, how this control is achieved prior to movement. We collected high-speed images of strike mechanics and electromyograms of the extensor and flexor muscles that control spring compression and latch release. During spring compression, lateral extensor and flexor units were co-activated. The strike initiated several milliseconds after the flexor units ceased, suggesting that flexor activity prevents spring release and determines the timing of strike initiation. We used linear mixed models and Akaike's information criterion to serially evaluate multiple hypotheses for control mechanisms. We found that variation in spring compression and strike angular velocity were statistically explained by spike activity of the extensor muscle. The results show that mantis shrimp can generate kinematically variable strikes and that their kinematics can be changed through adjustments to motor activity prior to the movement, thus supporting an upstream, central-nervous-system-based control of ultrafast movement. Based on these and other findings, we present a shishiodoshi model that illustrates alternative models of control in biological ballistic systems. The discovery of feed-forward control in mantis shrimp sets the stage for the assessment of targets, strategic variation in kinematics and the role of learning in ultrafast animals. © 2016.

    Does a religion shape belief-related decisions and influence neural processing? We investigated an eminent bishop of the Catholic Church in Germany by using functional magnetic resonance imaging (fMRI) to assess neural processing while he was responding to short sentences of the Christian Bible, the Islamic Quran, and the Daodejing ascribed to Laozi in Experiment 1. In Experiment 2, continuous praying was further compared to the resting state activity. In contrast to explicit statements of agreeing or not agreeing to different statements from the Bible and the Quran, we found in Experiment 1 no difference in neural activation when the bishop was reading these statements from the two religions. However, compared to reading statements from the Bible, reading statements from the Daodejing resulted in significantly higher activation in the left inferior and middle frontal cortices and the left middle temporal gyrus, although he equally agreed to both statements explicitly. In Experiment 2, no difference during continuous praying and the resting state activity was observed. Our results confirm the difference between explicit and implicit processing, and they suggest that a highly religious person may pray always-or never. On a more general level this observation suggests that ritualized activities might be subliminally represented in resting state activities. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

    Chopard (1916) published a brief paper in which he cited and described a number of praying mantis species from the neotropics. The specimens he studied belonged to the prominent Spanish Entomologist Ignacio Bolívar y Urrutia (1850-1944), whose collection is now housed at the Museo Nacional de Ciencias Naturales in Madrid (MNCN), Spain (Izquierdo et al. 1997). In this publication Chopard described Thespoides bolivari Chopard, 1916 as a new genus and species, based on a single male obtained by French coleopterist René Oberthür in Cauca, Colombia. According to Chopard (1916) the specimen was remarkable for having, among other features, an abdomen that is markedly shorter than the rest of its body-certainly an unusual morphological trait among the Mantodea. Chopard assigned Thespoides to the Miopteryginae (Thespidae), but it was later reassigned (together with Angela Serville, 1839 as the "Angelae group") to the subfamily Schizocephalinae (Mantidae) by Giglio-Tos (1927). Current classifications consider the Angelinae to comprise a distinct subfamily of the Mantidae, with Thespoides and Angela as the only representatives of this subfamily with a Neotropical distribution (e.g. Ehrmann 2002).

    In the present study a Swedish sample of 118 persons with chronic pain completed online tests on two occasions in association with treatment trials. A three item subscale measuring praying as a coping strategy was derived from the Coping Strategies Questionnaire (CSQ), but adapted to refer to "a higher power" instead of "God". Measures of pain and anxiety/depression were also included. Results revealed significant associations between praying and pain interference and impairment. Praying was also associated with anxiety and depression scores. Results also showed that prayer predicted depression scores at follow-up, and that follow-up prayer was predicted by pain interference at first measurement occasion. Overall, if prayer had any relation with the other variables it was in the negative direction of more distress being associated with more praying both concurrently and prospectively.

    Representative sampling has been completed for characterization of the residual material on the floor of Tank 19F as per the statistical sampling plan developed by Harris and Shine. Samples from eight locations have been obtained from the tank floor and two of the samples were archived as a contingency. Six samples, referred to in this report as the current scrape samples, have been submitted to and analyzed by SRNL. This report contains the statistical analysis of the floor sample analytical results to determine if further data are needed to reduce uncertainty. Included are comparisons with the prior Mantis samples resultsmore » to determine if they can be pooled with the current scrape samples to estimate the upper 95% confidence limits (UCL95%) for concentration. Statistical analysis revealed that the Mantis and current scrape sample results are not compatible. Therefore, the Mantis sample results were not used to support the quantification of analytes in the residual material. Significant spatial variability among the current scrape sample results was not found. Constituent concentrations were similar between the North and South hemispheres as well as between the inner and outer regions of the tank floor. The current scrape sample results from all six samples fall within their 3-sigma limits. In view of the results from numerous statistical tests, the data were pooled from all six current scrape samples. As such, an adequate sample size was provided for quantification of the residual material on the floor of Tank 19F. The uncertainty is quantified in this report by an UCL95% on each analyte concentration. The uncertainty in analyte concentration was calculated as a function of the number of samples, the average, and the standard deviation of the analytical results. The UCL95% was based entirely on the six current scrape sample results (each averaged across three analytical determinations).« less

    Introduction. Knowing that someone was entangled with cancer is a surprising experience for that person. Being aware of having cancer not only makes the person loose his hopes and ambitions, but also influences his body and mental. Meanwhile, religion can play the proper role of complementary treatment, increasing life expectancy in these patients. Objective. The study was conducted with the aim of determining the relationship between praying and life expectancy in cancerous patients. Method. This descriptive correlation study was performed on 96 malignant patients who were under chemotherapy in Golestan province in 1392. Paloma and Pendleton's Measure of Prayer Type questionnaires and Schneider questionnaire of life expectancy were used to collect this information. Analyses were performed by using SPSS 21.0. Data were analyzed by using the linear regression and the analytical significance was set at p < 0.05. Findings. The linear regression showed a significant relationship between life expectancy and praying (CI95:0.01-0.13), OR = 0.07, Beta = -0.24 P < 0.02) and in the light of previous experience it showed a significant relationship between praying and life expectancy. Conclusion. According to the obtained result of this study, cancerous patients can overcome their illness through praying, and they can also triumph cancer through self-confidence and control it, by getting more knowledge of their disease and become more hopeful about their future.

    Multiple nomenclatural problems persist in mantodean taxonomy. This constitutes an important challenge for praying mantis systematics, its forthcoming development and future consolidation. In this first contribution, we attempt solving a number of issues involving mostly Neotropical praying mantis species described by Brazilian entomologists Paulo S. Terra, Cândido F. de Mello-Leitão, Salvador de Toledo Piza Junior and Lauro J. Jantsch. We provide evidence to justify the following nomenclatural changes. In Acanthopidae, Acontiothespis travassosi Jantsch, 1986 is a new synonym of Raptrix perspicua (F. 1787). Changes in Thespidae are: Emboicy Terra, 1982 is a new synonym of Chloromiopteryx Giglio-Tos, 1915, E. mirim Terra, 1982 is transferred to Chloromiopteryx as C. mirim (Terra, 1982) (new combination); Musoniola plurilobata Mello-Leitão, 1937 is transferred to Chloromiopteryx as C. plurilobata (Mello-Leitão, 1937) (new combination); Metathespis modesta Piza, 1968 is removed from synonymy with Chloromiopteryx thalassina (Burmeister, 1838) and considered valid as C. modesta (Piza, 1968) (new combination and status revalidated); Metathespis precaria Piza, 1968 is removed from synonymy with Chloromiopteryx thalassina (Burmeister, 1838) and considered a new synonym of Miobantia rustica (Fabricius, 1781); Eumiopteryx magna Jantsch, 1991 is transferred to Anamiopteryx as A. magna (Jantsch, 1991) (new combination). For Mantidae/Amelinae, Tithrone corseuli Jantsch, 1986 and T. clauseni Jantsch, 1995 are new synonyms of Litaneutria minor (Scudder, 1872); in Mantidae/Photininae Coptopteryx gigliotosi Piza, 1960 (non Werner, 1925), its replacement name Coptopteryx ermannoi Jantsch & Corseuil, 1988 and Paraphotina precaria Piza, 1966 (the latter currently placed within Coptopteryx) are all new synonyms of Coptopteryx argentina (Burmeister, 1838), whereas Brachypteromantis bonariensis Piza 1960 (currently placed among Coptopteryx) is a new synonym of Coptopteryx gayi

The ion source is attached to a 3 grid 30 keV accelerator (also supplied by JAERI) and the accelerated negative ion current is determined from the energy deposited on a calorimeter located 1.6 m from the source.During experiments on MANTIS three adverse effects of long pulse operation were found: The negative ionmore » current to the calorimeter is {approx_equal}50% of that obtained from short pulse operation Increasing the plasma grid (PG) temperature results in {<=}40% enhancement in negative ion yield, substantially below that reported for short pulse operation, {>=}100%.

Additionally presented are the results of a detailed characterisation of the source, which enable the most efficient mode of operation to be identified.« less

  20. RECOMMENDATIONS FOR SAMPLING OF TANK 18 IN F TANK FARM

    Representative sampling is required for characterization of the residual floor material in Tank 18 prior to operational closure. Tank 18 is an 85-foot diameter, 34-foot high carbon steel tank with nominal operating volume of 1,300,000 gallons. It is a Type IV tank, and has been in service storing radioactive materials since 1959. Recent mechanical cleaning of the tank removed all mounds of material. Anticipating a low level of solids in the residual material, Huff and Thaxton [2009] developed a plan to sample the material during the final clean-up process while it would still be resident in sufficient quantities to supportmore » analytical determinations in four quadrants of the tank. Execution of the plan produced fewer solids than expected to support analytical determinations in all four quadrants. Huff and Thaxton [2009] then restructured the plan to characterize the residual floor material separately in the North and the South regions: two 'hemispheres.' This document provides sampling recommendations to complete the characterization of the residual material on the tank bottom following the guidance in Huff and Thaxton [2009] to split the tank floor into a North and a South hemisphere. The number of samples is determined from a modification of the formula previously published in Edwards [2001] and the sample characterization data for previous sampling of Tank 18 described by Oji [2009]. The uncertainty is quantified by an upper 95% confidence limit (UCL95%) on each analyte's mean concentration in Tank 18. The procedure computes the uncertainty in analyte concentration as a function of the number of samples, and the final number of samples is determined when the reduction in the uncertainty from an additional sample no longer has a practical impact on results. The characterization of the full suite of analytes in the North hemisphere is currently supported by a single Mantis rover sample obtained from a compact region near the center riser. A floor scrape

    Representative sampling has been completed for characterization of the residual material on the floor of Tank 18F as per the statistical sampling plan developed by Shine [1]. Samples from eight locations have been obtained from the tank floor and two of the samples were archived as a contingency. Six samples, referred to in this report as the current scrape samples, have been submitted to and analyzed by SRNL [2]. This report contains the statistical analysis of the floor sample analytical results to determine if further data are needed to reduce uncertainty. Included are comparisons with the prior Mantis samples resultsmore » [3] to determine if they can be pooled with the current scrape samples to estimate the upper 95% confidence limits (UCL{sub 95%}) for concentration. Statistical analysis revealed that the Mantis and current scrape sample results are not compatible. Therefore, the Mantis sample results were not used to support the quantification of analytes in the residual material. Significant spatial variability among the current sample results was not found. Constituent concentrations were similar between the North and South hemispheres as well as between the inner and outer regions of the tank floor. The current scrape sample results from all six samples fall within their 3-sigma limits. In view of the results from numerous statistical tests, the data were pooled from all six current scrape samples. As such, an adequate sample size was provided for quantification of the residual material on the floor of Tank 18F. The uncertainty is quantified in this report by an upper 95% confidence limit (UCL{sub 95%}) on each analyte concentration. The uncertainty in analyte concentration was calculated as a function of the number of samples, the average, and the standard deviation of the analytical results. The UCL{sub 95%} was based entirely on the six current scrape sample results (each averaged across three analytical determinations).« less

    Experimental data on the enhancement of D{sup {minus}} (H{sup {minus}}) negative ion production due to cesium injection into a large volume multiampere negative ion source (MANTIS) are described. The directed deposition of small cesium amounts (5{endash}100 mg) from a compact, movable oven, placed into the central part of a MANTIS gas-discharge box was used. A calorimetrically measured D{sup {minus}} beam with an intensity up to 1.6 A and an extracted current density up to 4.2 mA/cm{sup 2} (beam energy 25 kV) was obtained. Exactly 30 mg of cesium provides at least one month of source operation (1000 pulses with amore » discharge pulse duration of 4 s). The effect of cesium on NI enhancement was immediately displayed after the distributed Cs deposition, but it needed some {open_quote}{open_quote}conditioning{close_quote}{close_quote} of cesium by tens of discharge pulses (or by several hours {open_quote}{open_quote}pause{close_quote}{close_quote}) in the case of a localized Cs deposition.

    The flower-visiting behaviors of pollinator species are affected not only by flower traits but also by cues of predators and resident pollinators. There is extensive research into the effects of predator cues and resident pollinators on the flower-visiting behaviors of bee pollinators. However, there is relatively little research into their effects on butterfly pollinators probably because of the difficulty in observing a large number of butterfly pollination events. We conducted a dual choice experiment using artificial flowers under semi-natural conditions in the butterfly pavilion at Tama Zoological Park to examine the effects of the presence of a dead mantis and resident butterflies have on the flower-visiting behavior of several butterfly species. From 173 hours of recorded video, we observed 3235 visitations by 16 butterfly species. Statistical analysis showed that (1) butterflies avoided visiting flowers occupied by a dead mantis, (2) butterflies avoided resident butterflies that were larger than the visitor, and (3) butterflies showed greater avoidance of a predator when the predator was present together with the resident butterfly than when the predator was located on the opposite flower of the resident. Finally, we discuss the similarities and differences in behavioral responses of butterfly pollinators and bees.

    The family Toxoderidae (Mantodea) contains an ecologically diverse group of praying mantis species that have in common greatly elongated bodies. In this study, we sequenced and compared the complete mitochondrial genomes of two Toxoderidae species, Paratoxodera polyacantha and Toxodera hauseri, and compared their mitochondrial genome characteristics with another member of the Toxoderidae, Stenotoxodera porioni (KY689118). The lengths of the mitogenomes of T. hauseri and P. polyacantha were 15,616 bp and 15,999 bp, respectively, which is similar to that of S. porioni (15,846 bp). The size of each gene as well as the A+T-rich region and the A+T content of the whole genome were also very similar among the three species as were the protein-coding genes, the A+T content and the codon usages. The mitogenome of T. hauseri had the typical 22 tRNAs, whereas that of P. polyacantha had 26 tRNAs including an extra two copies of trnA-trnR. Intergenic regions of 67 bp and 76 bp were found in T. hauseri and P. polyacantha, respectively, between COX2 and trnK; these can be explained as residues of a tandem duplication/random loss of trnK and trnD. This non-coding region may be synapomorphic for Toxoderidae. In BI and ML analyses, the monophyly of Toxoderidae was supported and P. polyacantha was the sister clade to T. hauseri and S. porioni.

    a function of the number of samples, and the final number of samples is determined when the reduction in the uncertainty from an additional sample no longer has a practical impact on results. The characterization of the full suite of analytes in the North and South hemispheres is currently supported by a single Mantis rover sample in each hemisphere. A floor scrape sample was obtained from a compact region near the center riser slightly in the South hemisphere and has been analyzed for a shortened list of key analytes. There is not enough additional material from the floor scrape sample material for completing the full suite of constituents. No floor scrape samples have been previously taken from the North hemisphere. The criterion to determine the number of additional samples was based on the practical reduction in the uncertainty when a new sample is added. This was achieved when five additional samples are obtained. In addition, two archived samples will be used if a contingency such as failing to demonstrate the comparability of the Mantis samples to the floor scrape samples occurs. To complete sampling of the Tank 19 residual floor material, four additional samples should be taken from the North hemisphere and four additional samples should be taken from the South hemisphere. One of the samples from each hemisphere will be archived in case of need. Three of the four additional samples from each hemisphere will be analyzed. Once the results are available, differences between the Mantis and three floor scrape sample results will be evaluated. If there are no statistically significant analyte concentration differences between the Mantis and floor scrape samples, those results will be combined and then UCL95%s will be calculated. If the analyte concentration differences between the Mantis and floor scrape samples are statistically significant, the UCL95%s will be calculated without the Mantis sample results.

    The sitting position has lost favor among neurosurgeons partly owing to assumptions of increased complications, such as venous air embolisms and hemodynamic disturbances. Moreover, the surgeon must assume a tiring posture. We describe our protocol for the "praying position" for pineal region surgery; this variant may reduce some of the risks of the sitting position, while providing a more ergonomic surgical position. A retrospective review of 56 pineal lesions operated on using the praying position between January 2008 and October 2015 was performed. The praying position is a steeper sitting position with the upper torso and the head bent forward and downward. The patient's head is tilted about 30° making the tentorium almost horizontal, thus providing a good viewing angle. G-suit trousers or elastic bandages around the lower extremities are always used. Complete lesion removal was achieved in 52 cases; subtotal removal was achieved in 4. Venous air embolism associated with persistent hemodynamic changes was nonexistent in this series. When venous air embolism was suspected, an immediate reaction based on good teamwork was imperative. No cervical spine cord injury or peripheral nerve damage was reported. The microsurgical time was <45 minutes in most of the cases. Postoperative pneumocephalus was detected in all patients, but no case required surgical treatment. A protocolized praying position that includes proper teamwork management may provide a simple, fast, and safe approach for proper placement of the patient for pineal region surgery.

    Countless aquatic animals rotate appendages through the water, yet fluid forces are typically modeled with translational motion. To elucidate the hydrodynamics of rotation, we analyzed the raptorial appendages of mantis shrimp (Stomatopoda) using a combination of flume experiments, mathematical modeling and phylogenetic comparative analyses. We found that computationally efficient blade-element models offered an accurate first-order approximation of drag, when compared with a more elaborate computational fluid-dynamic model. Taking advantage of this efficiency, we compared the hydrodynamics of the raptorial appendage in different species, including a newly measured spearing species, Coronis scolopendra The ultrafast appendages of a smasher species (Odontodactylus scyllarus) were an order of magnitude smaller, yet experienced values of drag-induced torque similar to those of a spearing species (Lysiosquillina maculata). The dactyl, a stabbing segment that can be opened at the distal end of the appendage, generated substantial additional drag in the smasher, but not in the spearer, which uses the segment to capture evasive prey. Phylogenetic comparative analyses revealed that larger mantis shrimp species strike more slowly, regardless of whether they smash or spear their prey. In summary, drag was minimally affected by shape, whereas size, speed and dactyl orientation dominated and differentiated the hydrodynamic forces across species and sizes. This study demonstrates the utility of simple mathematical modeling for comparative analyses and illustrates the multi-faceted consequences of drag during the evolutionary diversification of rotating appendages. © 2016.

    2017-12-01

    The Bouligand structure, which is found in many biological materials, is a hierarchical architecture that features uniaxial fiber layers assembled periodically into a helicoidal pattern. Many studies have highlighted the high damage-resistant performance of natural and biomimetic Bouligand structures. One particular species that utilizes the Bouligand structure to achieve outstanding mechanical performance is the smashing Mantis Shrimp, Odontodactylus Scyllarus (or stomatopod). The mantis shrimp generates high speed, high acceleration blows using its raptorial appendage to defeat highly armored preys. The load-bearing part of this appendage, the dactyl club, contains an interior region [16] that consists of a Bouligand structure. This region is capable of developing a significant amount of nested twisting microcracks without exhibiting catastrophic failure. The development and propagation of these microcracks are a source of energy dissipation and stress relaxation that ultimately contributes to the remarkable damage tolerance properties of the dactyl club. We develop a theoretical model to provide additional insights into the local stress intensity factors at the crack front of twisting cracks formed within the Bouligand structure. Our results reveal that changes in the local fracture mode at the crack front leads to a reduction of the local strain energy release rate, hence, increasing the necessary applied energy release rate to propagate the crack, which is quantified by the local toughening factor. Ancillary 3D simulations of the asymptotic crack front field were carried out using a J-integral to validate the theoretical values of the energy release rate and the local stress intensity factors.

    This project aims to assess the utility of bibliographic databases beyond the three major ones (MEDLINE, EMBASE and Cochrane CENTRAL) for finding controlled trials of complementary and alternative medicine (CAM). Fifteen databases were searched to identify controlled clinical trials (CCTs) of CAM not also indexed in MEDLINE. Searches were conducted in May 2006 using the revised Cochrane highly sensitive search strategy (HSSS) and the PubMed CAM Subset. Yield of CAM trials per 100 records was determined, and databases were compared over a standardized period (2005). The Acudoc2 RCT, Acubriefs, Index to Chiropractic Literature (ICL) and Hom-Inform databases had the highest concentrations of non-MEDLINE records, with more than 100 non-MEDLINE records per 500. Other productive databases had ratios between 500 and 1500 records to 100 non-MEDLINE records—these were AMED, MANTIS, PsycINFO, CINAHL, Global Health and Alt HealthWatch. Five databases were found to be unproductive: AGRICOLA, CAIRSS, Datadiwan, Herb Research Foundation and IBIDS. Acudoc2 RCT yielded 100 CAM trials in the most recent 100 records screened. Acubriefs, AMED, Hom-Inform, MANTIS, PsycINFO and CINAHL had more than 25 CAM trials per 100 records screened. Global Health, ICL and Alt HealthWatch were below 25 in yield. There were 255 non-MEDLINE trials from eight databases in 2005, with only 10% indexed in more than one database. Yield varied greatly between databases; the most productive databases from both sampling methods were Acubriefs, Acudoc2 RCT, AMED and CINAHL. Low overlap between databases indicates comprehensive CAM literature searches will require multiple databases. PMID:19468052

Five databases were found to be unproductive: AGRICOLA, CAIRSS, Datadiwan, Herb Research Foundation and IBIDS. Acudoc2 RCT yielded 100 CAM trials in the most recent 100 records screened. Acubriefs, AMED, Hom-Inform, MANTIS, PsycINFO and CINAHL had more than 25 CAM trials per 100 records screened. Global Health, ICL and Alt HealthWatch were below 25 in yield. There were 255 non-MEDLINE trials from eight databases in 2005, with only 10% indexed in more than one database. Yield varied greatly between databases; the most productive databases from both sampling methods were Acubriefs, Acudoc2 RCT, AMED and CINAHL. Low overlap between databases indicates comprehensive CAM literature searches will require multiple databases.

  19. Curvature facilitates prey fixation in predatory insect claws.

    Insects show a large variety in prey capture strategies, with a correspondingly large diversity in predatory adaptations. We studied a specific type of predatory claws, these can for example be found in praying mantis species. The claw is closeable over its entire length and the prey is fixed between the femur (upper arm) and the tibia (lower arm) of the insect leg. The morphology of these predatory claws is diverse. Some species have straight claws covered with spines, while other species have smooth, curved claws. We have studied the mechanics of this femur-tibia type of predatory insect claws, by making a physical model, eventually trying to explain why in some insect species the claws are curved instead of straight. The main results are (1) when comparing curved claws to straight claws, curvature leads to a strong reduction of forces driving the prey away from the pivoting point, thereby reducing the need for friction generating structures. (2) In the curved claw model a position exists where the resulting force on the prey is exactly zero. This is because the normal forces on the femur and tibia are opposed, and in line. At this position the prey is perfectly clamped and not driven out of the claw. This feature does not exist in straight claws. (3) In the curved claw, the prey cannot be placed at a position further than a certain maximum distance from the pivoting point. Near this maximum position, the resulting force on the prey reaches high values because moment arms are near zero. (4) Between the zero position and the maximum position the resulting force is directed toward the pivoting point, which stabilizes prey fixation.

    Chinese traditional praying paper industry is an industry which produced Chinese traditional religion praying paper. This kind of industry is rarely examined since it was only in Small and Medium Enterprise (SME’s- form). This industry produced various kinds of Chinese traditional paper products. The purpose of this research is to increase the amount of production, reduce waiting time and moving time, and reduce material handling cost. The research was conducted at prime production activities, consists of: calculate the capacity of the material handler, the frequency of movement, cost of material handling, and total cost of material handling. This displacement condition leads to an ineffective and inefficient production process. The alternative was developed using production judgment and aisle standard. Based on the observation results, it is possible to reduce displacement in the production. Using alternative which by-passed displacement from a rolled paper in the temporary warehouse to cutting and printing workstation, it can reduce material handling cost from 2.26 million rupiahs to 2.00 million rupiahs only for each batch of production. This result leads to increasing of production quantity, reducing waiting and moving time about 10% from the current condition.

    Southern Hemisphere humpback whales (Megaptera novaeangliae) generally undertake annual migrations from polar summer feeding grounds to winter calving and nursery grounds in subtropical and tropical coastal waters. Evidence for such migrations arises from seasonality of historic whaling catches by latitude, Discovery and natural mark returns, and results of satellite tagging studies. Feeding is generally believed to be limited to the southern polar region, where Antarctic krill (Euphausia superba) has been identified as the primary prey item. Non-migrations and / or suspended migrations to the polar feeding grounds have previously been reported from a summer presence of whales in the Benguela System, where feeding on euphausiids (E. lucens), hyperiid amphipods (Themisto gaudichaudii), mantis shrimp (Pterygosquilla armata capensis) and clupeid fish has been described. Three recent research cruises (in October/November 2011, October/November 2014 and October/November 2015) identified large tightly-spaced groups (20 to 200 individuals) of feeding humpback whales aggregated over at least a one-month period across a 220 nautical mile region of the southern Benguela System. Feeding behaviour was identified by lunges, strong milling and repetitive and consecutive diving behaviours, associated bird and seal feeding, defecations and the pungent "fishy" smell of whale blows. Although no dedicated prey sampling could be carried out within the tightly spaced feeding aggregations, observations of E. lucens in the region of groups and the full stomach contents of mantis shrimp from both a co-occurring predatory fish species (Thyrsites atun) and one entangled humpback whale mortality suggest these may be the primary prey items of at least some of the feeding aggregations. Reasons for this recent novel behaviour pattern remain speculative, but may relate to increasing summer humpback whale abundance in the region.

  3. Anisotropic imaging performance in indirect x-ray imaging detectors

    Badano, Aldo; Kyprianou, Iacovos S.; Sempau, Josep

    We report on the variability in imaging system performance due to oblique x-ray incidence, and the associated transport of quanta (both x rays and optical photons) through the phosphor, in columnar indirect digital detectors. The analysis uses MANTIS, a combined x-ray, electron, and optical Monte Carlo transport code freely available. We describe the main features of the simulation method and provide some validation of the phosphor screen models considered in this work. We report x-ray and electron three-dimensional energy deposition distributions and point-response functions (PRFs), including optical spread in columnar phosphor screens of thickness 100 and 500 {mu}m, for 19,more » 39, 59, and 79 keV monoenergetic x-ray beams incident at 0 deg., 10 deg., and 15 deg. . In addition, we present pulse-height spectra for the same phosphor thickness, x-ray energies, and angles of incidence. Our results suggest that the PRF due to the phosphor blur is highly nonsymmetrical, and that the resolution properties of a columnar screen in a tomographic, or tomosynthetic imaging system varies significantly with the angle of x-ray incidence. Moreover, we find that the noise due to the variability in the number of light photons detected per primary x-ray interaction, summarized in the information or Swank factor, is somewhat independent of thickness and incidence angle of the x-ray beam. Our results also suggest that the anisotropy in the PRF is not less in screens with absorptive backings, while the noise introduced by variations in the gain and optical transport is larger. Predictions from MANTIS, after additional validation, can provide the needed understanding of the extent of such variations, and eventually, lead to the incorporation of the changes in imaging performance with incidence angle into the reconstruction algorithms for volumetric x-ray imaging systems.« less

    The efficacy of attractive toxic sugar baits (ATSB) with the active ingredient eugenol, an Environmental Protection Agency exempt compound, was evaluated against vector and nuisance mosquitoes in both laboratory and field studies. In the laboratory, eugenol combined in attractive sugar bait (ASB) solution provided high levels of mortality for Aedes aegypti, Culex quinquefasciatus, and Anopheles quadrimaculatus. Field studies demonstrated significant control: > 70% reduction for Aedes atlanticus, Ae. infirmatus, and Culex nigripalpus and > 50% reduction for An. crucians, Uranotaenia sapphirina, Culiseta melanura, and Cx. erraticus three weeks post ATSB application. Furthermore, non-target feeding of six insect orders, Hymenoptera, Lepidoptera, Coleoptera, Diptera, Hemiptera, and Orthoptera, was evaluated in the field after application of a dyed-ASB to flowering and non-flowering vegetation. ASB feeding (staining) was determined by dissecting the guts and searching for food dye with a dissecting microscope. The potential impact of ATSB on non-targets, applied on green non-flowering vegetation was low for all non-target groups (0.9%). However, application of the ASB to flowering vegetation resulted in significant staining of the non-target insect orders. This highlights the need for application guidelines to reduce non-target effects. No mortality was observed in laboratory studies with predatory non-targets, spiders, praying mantis, or ground beetles, after feeding for three days on mosquitoes engorged on ATSB. Overall, our laboratory and field studies support the use of eugenol as an active ingredient for controlling important vector and nuisance mosquitoes when used as an ATSB toxin. This is the first study demonstrating effective control of anophelines in non-arid environments which suggest that even in highly competitive sugar rich environments this method could be used for control of malaria in Latin American countries.

  6. Filtering and polychromatic vision in mantis shrimps: themes in visible and ultraviolet vision.

    2014-01-01

    Stomatopod crustaceans have the most complex and diverse assortment of retinal photoreceptors of any animals, with 16 functional classes. The receptor classes are subdivided into sets responsible for ultraviolet vision, spatial vision, colour vision and polarization vision. Many of these receptor classes are spectrally tuned by filtering pigments located in photoreceptors or overlying optical elements. At visible wavelengths, carotenoproteins or similar substances are packed into vesicles used either as serial, intrarhabdomal filters or lateral filters. A single retina may contain a diversity of these filtering pigments paired with specific photoreceptors, and the pigments used vary between and within species both taxonomically and ecologically. Ultraviolet-filtering pigments in the crystalline cones serve to tune ultraviolet vision in these animals as well, and some ultraviolet receptors themselves act as birefringent filters to enable circular polarization vision. Stomatopods have reached an evolutionary extreme in their use of filter mechanisms to tune photoreception to habitat and behaviour, allowing them to extend the spectral range of their vision both deeper into the ultraviolet and further into the red.

    Crustacea Decapoda and Stomatopoda are inventoried for the first time in Juan de Nova Island, Iles Eparses, Mozambique channel. In total, 112 species are reported: 69 crabs, 28 anomurans, 11 shrimps, 3 mantis shrimps and 1 lobster. A comparison is made with nearby islands in the Mozambique channel: Glorieuses Islands (157 species), Europa Island (178 species), and Mayotte Island (505 species). The lower species richness at Juan de Nova is explained by the small size of the island and by the difficulties to collect the crustaceans on the reef flat hardly accessible at low tide. The crustaceans are listed by main habitats from land to outer reef (2-20 m). The presence of the coconut crab (Birgus latro), an endangered species vulnerable to human predation, is confirmed.

    1997-04-01

    We undertook a preliminary investigation of the cuticular extracts of five common mantid species in the eastern United States: Tenodera sinensis (Saussure), T. angustipennis (Saussure) and Mantis religiosa (Linnaeus) introduced from the Old World and Stagmomantis carolina (Johannson) and Bruneria borealis (Scudder), which are New World species. The major components of these mixtures were normal alkanes, predominately hentriacontane, or in the case of the parthenogenic species B. borealis, tritriacontane. Tricontanal was detected in the extracts of all five species, and smaller amounts of other aldehydes and n-tricontanol were detected in some species. Complex mixtures of methyl and dimethylalkanes also were present in these extracts. The composition of the cuticular hydrocarbons of these mantids may be an adaptation for reduction of evaporative water loss in these insects that inhabit open fields.

    Abstract Several new records are presented on some of the least known mantis species in the Iberian Peninsula. From data collected in Portugal, their analysis has proven to represent an important advancement in the knowledge of this group of insects for the country and the Western Mediterranean area. Twenty new citations provide a better understanding on the distribution of the crepuscular species Perlamantis allibertii, the IUCN red listed Apteromantis aptera and the first Portuguese records of Sphodromantis viridis, extending their western limits of occurrence in Europe. The data thus gathered emphasizes the need to invest in biodiversity assessment for increased knowledge on species distribution and phenology but also for monitoring over time, essential to better ascertaining ecosystem services, the effects of climate change and habitat conservation.

The analysis takes into account the most common operating systems—TinyOS v1.0, TinyOS v2.0, Mantis and Contiki—running on Tmote Sky and MICAz devices. With the objective of ensuring a fair evaluation, a benchmark composed of four applications has been developed, covering the most typical tasks that a Wireless Sensor Network performs. The results show the instant and average current consumption of the devices during the execution of these applications. The experimental measurements provide a good insight into the power mode in which the device components are running at every moment, and they can be used to compare the performance of different operating systems executing the same tasks.

This poses several problems for the neutral beam injection systems that are currently in use. The power loading of the ion source and accelerator are especially problematic. The Kamaboko negative ion source, a small scale model of the ITER arc source, is being prepared for extended operation of deuterium beams for up to 1000 seconds.

    Comparative biomechanics offers an opportunity to explore the evolution of disparate biological systems that share common underlying mechanics. Four-bar linkage modeling has been applied to various biological systems such as fish jaws and crustacean appendages to explore the relationship between biomechanics and evolutionary diversification. Mechanical sensitivity states that the functional output of a mechanical system will show differential sensitivity to changes in specific morphological components. We document similar patterns of mechanical sensitivity in two disparate four-bar systems from different phyla: the opercular four-bar system in centrarchid fishes and the raptorial appendage of stomatopods. We built dynamic linkage models of 19 centrarchid and 36 stomatopod species and used phylogenetic generalized least squares regression (PGLS) to compare evolutionary shifts in linkage morphology and mechanical outputs derived from the models. In both systems, the kinematics of the four-bar mechanism show significant evolutionary correlation with the output link, while travel distance of the output arm is correlated with the coupler link. This common evolutionary pattern seen in both fish and crustacean taxa is a potential consequence of the mechanical principles underlying four-bar systems. Our results illustrate the potential influence of physical principles on morphological evolution across biological systems with different structures, behaviors, and ecologies. © 2017 The Author(s).

    2016-01-01

    Ultrasonic fragmentation, which is a simple and convenient method for the mechanical degradation of DNA, is widely used in modern genome studies as one of the sample preparation steps. It has been recently found that the DNA breaks occur more often in the regions containing 5'-CG-3' dinucleotides. We studied the influence of the 5'-CG-3' dinucleotides on the efficiency of the 28S rRNA gene amplification during PCR with sonicated DNA of Mantis religiosa. It was shown that the amplification rate depends on the template length and the number of 5'-CG-3' dinucleotides. Amplification of the DNA regions with a higher 5'-CG-3' density is less efficient because of their higher sensitivity to ultrasound. The amount of the amplified DNA templates is inversely proportional to the 5'-CG-3'number.

  18. A Functional Subnetwork Approach to Designing Synthetic Nervous Systems That Control Legged Robot Locomotion

    2017-01-01

    A dynamical model of an animal’s nervous system, or synthetic nervous system (SNS), is a potentially transformational control method. Due to increasingly detailed data on the connectivity and dynamics of both mammalian and insect nervous systems, controlling a legged robot with an SNS is largely a problem of parameter tuning. Our approach to this problem is to design functional subnetworks that perform specific operations, and then assemble them into larger models of the nervous system. In this paper, we present networks that perform addition, subtraction, multiplication, division, differentiation, and integration of incoming signals. Parameters are set within each subnetwork to produce the desired output by utilizing the operating range of neural activity, R, the gain of the operation, k, and bounds based on biological values. The assembly of large networks from functional subnetworks underpins our recent results with MantisBot. PMID:28848419

    Over millions of years, the crustacean exoskeleton has evolved into a rigid, tough, and complex cuticle that is used for structural support, mobility, protection of vital organs, and defense against predation. The crustacean cuticle is characterized by a hierarchically arranged chitin fiber scaffold, mineralized predominately by calcium carbonate and/or calcium phosphate. The structural organization of the mineral and organic within the cuticle occurs over multiple length scales, resulting in a strong and tough biological composite. Here, the ultrastructural details observed in three species of crustacean are reviewed: the American lobster (Homarus americanus), the edible crab (Cancer pagurus), and the peacock mantis shrimp (Odontodactylus scyllarus). The Review concludes with a discussion of recent advances in the development of biomimetics with controlled organic scaffolding, mineralization, and the construction of nanoscale composites, inspired by the organization and formation of the crustacean cuticle. © 2014 WILEY-VCH Verlag GmbH & Co.

    Natarajan, Bharath; Gilman, Jeffrey W.

    2017-12-01

    The twisted plywood, or Bouligand, structure is the most commonly observed microstructural motif in natural materials that possess high mechanical strength and toughness, such as that found in bone and the mantis shrimp dactyl club. These materials are isotropically toughened by a low volume fraction of soft, energy-dissipating polymer and by the Bouligand structure itself, through shear wave filtering and crack twisting, deflection and arrest. Cellulose nanocrystals (CNCs) are excellent candidates for the bottom-up fabrication of these structures, as they naturally self-assemble into `chiral nematic' films when cast from solutions and possess outstanding mechanical properties. In this article, we present a review of the fabrication techniques and the corresponding mechanical properties of Bouligand biomimetic CNC nanocomposites, while drawing comparison to the performance standards set by tough natural composite materials. This article is part of a discussion meeting issue `New horizons for cellulose nanotechnology'.

    An increasing number of hand-held scanning systems by different manufacturers are becoming available on the market. However, their geometrical performance is little-known to many users. Therefore the Laboratory for Photogrammetry & Laser Scanning of the HafenCity University Hamburg has carried out geometrical accuracy tests with the following systems in co-operation with the Bochum University of Applied Sciences (Laboratory for Photogrammetry) as well as the Humboldt University in Berlin (Institute for Computer Science): DOTProduct DPI-7, Artec Spider, Mantis Vision F5 SR, Kinect v1 + v2, Structure Sensor and Google's Project Tango. In the framework of these comparative investigations geometrically stable reference bodies were used. The appropriate reference data were acquired by measurement with two structured light projection systems (AICON smartSCAN and GOM ATOS I 2M). The comprehensive test results of the different test scenarios are presented and critically discussed in this contribution.

    We report the results of two surveys targeting praying mantises in four localities in Rwanda, specifically Akagera National Park, Nyungwe National Park, Volcanoes National Park, and the Arboretum de Ruhande at the National University of Rwanda. Using an assortment of collecting techniques, including metal halide light traps, sweep netting vegetation and general searching, we obtained 387 adult and 352 juvenile specimens, representing 41 species. A total of 28 novel species records for Rwanda are added to the 18 previously recorded species for the country, in addition to 20 novel species records for the broader region, including neighbouring Uganda and Burundi. This study provides high resolution images of the dorsal habitus of both sexes of representative species, both pinned and living. Species distribution records are presented and discussed. With a 155% increase in species recorded from Rwanda, this survey illustrates the need for further taxonomic work in the region.

Three cancer centers that are part of a university-affiliated comprehensive cancer network in the northeastern United States. 13 adult, female outpatients receiving active treatment for ovarian or lung cancer. Two semistructured, focus group interviews were conducted. Audiotapes were transcribed verbatim. Data were coded and analyzed using standard content analysis procedures. Prayer and coping. Four themes emerged: finding one's own way, renewed appreciation for life, provision of strength and courage, and gaining a stronger spiritual connection. In addition, praying for others, conversational prayer, petitionary prayer, ritual prayer, and thanksgiving prayer were used most often by participants to cope. The findings support prayer as a positive coping mechanism for women with advanced ovarian or lung cancer. The study provides knowledge about prayer as a source of spiritual and psychological support. Oncology nurses should consider the use of prayer for patients coping with advanced cancer.

    Chiropractors claim to locate, analyze and diagnose a putative spinal lesion known as subluxation and apply the mode of spinal manipulation (adjustment) for the correction of this lesion. The purpose of this examination is to review the current evidence on the epidemiology of the subluxation construct and to evaluate the subluxation by applying epidemiologic criteria for it's significance as a causal factor. The databases of PubMed, Cinahl, and Mantis were searched for studies using the keywords subluxation, epidemiology, manipulation, dose-response, temporality, odds ratio, relative risk, biological plausibility, coherence, and analogy. The criteria for causation in epidemiology are strength (strength of association), consistency, specificity, temporality (temporal sequence), dose response, experimental evidence, biological plausibility, coherence, and analogy. Applied to the subluxation all of these criteria remain for the most part unfulfilled. There is a significant lack of evidence to fulfill the basic criteria of causation. This lack of crucial supportive epidemiologic evidence prohibits the accurate promulgation of the chiropractic subluxation.

    Background Chiropractors claim to locate, analyze and diagnose a putative spinal lesion known as subluxation and apply the mode of spinal manipulation (adjustment) for the correction of this lesion. Aim The purpose of this examination is to review the current evidence on the epidemiology of the subluxation construct and to evaluate the subluxation by applying epidemiologic criteria for it's significance as a causal factor. Methods The databases of PubMed, Cinahl, and Mantis were searched for studies using the keywords subluxation, epidemiology, manipulation, dose-response, temporality, odds ratio, relative risk, biological plausibility, coherence, and analogy. Results The criteria for causation in epidemiology are strength (strength of association), consistency, specificity, temporality (temporal sequence), dose response, experimental evidence, biological plausibility, coherence, and analogy. Applied to the subluxation all of these criteria remain for the most part unfulfilled. Conclusion There is a significant lack of evidence to fulfill the basic criteria of causation.

    Context: The effect of the application of kinesiotape to skin overlying musculature on measurable athletic-based performance outcomes in healthy individuals has not been well established. Objective: To systematically search and assess the quality of the literature on the effect of kinesiotape on athletic-based performance outcomes in healthy, active individuals. Methods: An electronic search strategy was conducted in MANTIS, Cochrane Library and EBSCO databases. Retrieved articles that met the eligibility criteria were rated for methodological quality by using an adaption of the critical appraisal criteria in Clinical Epidemiology by Sackett et al. Results: Ten articles met the inclusion criteria. Seven articles had positive results in at least one athletic-based performance measure compared to controls. Conclusion: Evidence is lacking to support the use of kinesiotape as a successful measure for improving athletic-based performance outcomes in healthy individuals. However, there is no evidence to show that kinesiotape has a negative effect on any of the performace measures. PMID:24302784

    Mechanical redundancy within a biomechanical system (e.g., many-to-one mapping) allows morphologically divergent organisms to maintain equivalent mechanical outputs. However, most organisms depend on the integration of more than one biomechanical system. Here, we test whether coupled mechanical systems follow a pattern of amplification (mechanical changes are congruent and evolve toward the same functional extreme) or independence (mechanisms evolve independently). We examined the correlated evolution and evolutionary pathways of the coupled four-bar linkage and lever systems in mantis shrimp (Stomatopoda) ultrafast raptorial appendages. We examined models of character evolution in the framework of two divergent groups of stomatopods-"smashers" (hammer-shaped appendages) and "spearers" (bladed appendages). Smashers tended to evolve toward force amplification, whereas spearers evolved toward displacement amplification. These findings show that coupled biomechanical systems can evolve synergistically, thereby resulting in functional amplification rather than mechanical redundancy. © 2014 The Author(s).

    1982-07-01

    A total of 36 samples of shrimp were examined from the region of the Buccaneer oil field, eighteen of which were representatives of the commercial species Penaeus aztecus and the rest were various other species: Penaeus duorarum (pink shrimp), Trachypenaeus duorarum (sugar shrimp), Squilla empusa (mantis shrimp), and Sicyonia dorsalis (chevron shrimp). The alkanes and deuteriated alkanes were completely separated by GC, so a mass spectrometer was not required for their detection and quantitation. To confirm the identities of individual compounds, however, some samples were examined by combined gas chromatography-mass spectrometry. Results show that only thirteen of the forty shrimpmore » collected from the region of the Buccaneer oil field contained petroleum alkanes, and the majority of these were obtained from trawls immediately adjacent to the production platforms. It appears that shrimp caught in the region of the Buccaneer oil field are not appreciably tainted with hydrocarbons discharged from the production platforms. (JMT)« less

    PubMed Central

    2014-01-01

    Abstract The recent growing interest on the Mantodea fauna of southern Europe and Portugal in particular, has enabled the discovery of two geographically separated populations of hitherto unknown species in Europe. Analysis of specimens shows that they belong to two Afrotropical mantids: Miomantis caffra Saussure, 1871 and Miomantis paykullii Stal, 1871, thus raising the number of known species in Europe to 39 and in Portugal to 11. While these are remarkable findings, they also represent the first alien mantis species recorded from this continent. As yet, these species appear to be confined to artificial humanised gardened areas but call for more attention to the problem of biological invasions and the need for better bio-security measures for the conservation of natural ecosystems. In the absence of recent revisionary work on the Mantodea of Portugal and given the need to provide an accessible identification tool, both a checklist and a key to species are provided for all species in the country.

    The dependency paradox (Feeney) states that independence actually can result from being in a nurturing relationship. Those who divorce often have the opposite notion that independence will occur without a relationship. The movies Eat, Pray, Love, An Unmarried Woman, and Kramer vs. Kramer examine divorce from different angles. The protagonists in all three movies grow through the process of divorce, each achieving a level of autonomy that seemed unattainable within their marriage. This paper aims to explore the concept of divorce in light of the dependency paradox by examining the self-differentiation achieved and the consequences of such independence for both the individual and, in Kramer vs. Kramer, for the child involved.

    The complex hierarchical structure in biological and synthetic fibrous nanocomposites entails considerable difficulties in the interpretation of the crystallographic texture from diffraction data. Here, we present a novel reconstruction method to obtain the 3D distribution of fibres in such systems. An analytical expression is derived for the diffraction intensity from fibres, explaining the azimuthal intensity distribution in terms of the angles of the three dimensional fibre orientation distributions. The telson of stomatopod (mantis shrimp) serves as an example of natural biological armour whose high impact resistance property is believed to arise from the hierarchical organization of alpha chitin nanofibrils into fibres and twisted plywood (Bouligand) structures at the sub-micron and micron scale. Synchrotron microfocus scanning X-ray diffraction data on stomatopod telson were used as a test case to map the 3D fibre orientation across the entire tissue section. The method is applicable to a range of biological and biomimetic structures with graded 3D fibre texture at the sub-micron and micron length scales.

    Background Part II of this review examines the functional "short leg" or unloaded leg length alignment asymmetry, including the relationship between an anatomic and functional leg-length inequality. Based on the reviewed evidence, an outline for clinical decision making regarding functional and anatomic leg-length inequality will be provided. Methods Online databases: Medline, CINAHL and Mantis. Plus library searches for the time frame of 1970–2005 were done using the term "leg-length inequality". Results and Discussion The evidence suggests that an unloaded leg-length asymmetry is a different phenomenon than an anatomic leg-length inequality, and may be due to suprapelvic muscle hypertonicity. Anatomic leg-length inequality and unloaded functional or leg-length alignment asymmetry may interact in a loaded (standing) posture, but not in an unloaded (prone/supine) posture. Conclusion The unloaded, functional leg-length alignment asymmetry is a likely phenomenon, although more research regarding reliability of the measurement procedure and validity relative to spinal dysfunction is needed. Functional leg-length alignment asymmetry should be eliminated before any necessary treatment of anatomic LLI. PMID:16080787

    The sound generated by the flow around a circular cylinder is numerically investigated by using a finite-element method. In particular, we study the acoustic emissions generated by the flow past the bluff body at low Mach and Reynolds numbers. We perform a global stability analysis by using the compressible linearized Navier-Stokes equations. The resulting direct global mode provides detailed information related to the underlying hydrodynamic instability and data on the acoustic field generated. In order to recover the intensity of the produced sound, we apply the self-consistent model for non-linear saturation proposed by Mantič-Lugo, Arratia, and Gallaire ["Self-consistent mean flow description of the nonlinear saturation of the vortex shedding in the cylinder wake," Phys. Rev. Lett. 113, 084501 (2014)]. The application of this model allows us to compute the amplitude of the resulting linear mode and the effects of saturation on the mode structure and acoustic field. Our results show excellent agreement with those obtained by a full compressible simulation direct numerical simulation and those derived by the application of classical acoustic analogy formulations.

    Global marine N budgets often show deficits due to dominance of benthic N2 production relative to pelagic N2 fixation. Recent studies have argued that benthic N2 fixation in shallow water environments has been underestimated. In particular, N2 fixation associated with animal burrows may be significant as indicated by high rates of N2 fixation reported in muddy sands populated by the ghost shrimp, Neotrypaea californiensis (Bertics et al., 2010). We investigated whether N2 fixation occurs at higher rates in the burrow-walls of the deep-burrowing ( 0.5-4 m) mantis shrimp, Squilla empusa, compared to ambient, estuarine muds and measured seasonal in-situ N2 concentrations in burrow-water relative to bottom-water. Acetylene reduction assays showed lower N2 fixation in burrow-walls than in un-populated sediments, likely due to inhibitory effects of O2 on ethylene production. Dissolved N2 was higher in burrow-water than proximate bottom-water at all seasons, demonstrating a consistent balance of net N2 production relative to fixation in deep-tier biogenic structures.

    A systematic review was conducted to assess the level of evidence for integrative health care research. We searched PubMed, Allied and Complementary Medicine (AMED), BIOSIS Previews, EMBASE, the entire Cochrane Library, MANTIS, Social SciSearch, SciSearch Cited Ref Sci, PsychInfo, CINAHL, and NCCAM grantee publications listings, from database inception to May 2009, as well as searches of the “gray literature.” Available studies published in English language were included. Three independent reviewers rated each article and assessed the methodological quality of studies using the Scottish Intercollegiate Guidelines Network (SIGN 50). Our search yielded 11,891 total citations but 6 clinical studies, including 4 randomized, met our inclusion criteria. There are no available systematic reviews/meta-analyses published that met our inclusion criteria. The methodological quality of the included studies was assessed independently using quality checklists of the SIGN 50. Only a small number of RCTs and CCTs with a limited number of patients and lack of adequate control groups assessing integrative health care research are available. These studies provide limited evidence of effective integrative health care on some modalities. However, integrative health care regimen appears to be generally safe. PMID:20953383

  19. Unleashing elastic energy: dynamics of energy release in rubber bands and impulsive biological systems

    NASA Astrophysics Data System (ADS)

    Ilton, Mark; Cox, Suzanne; Egelmeers, Thijs; Patek, S. N.; Crosby, Alfred J.

    Impulsive biological systems - which include mantis shrimp, trap-jaw ants, and venus fly traps - can reach high speeds by using elastic elements to store and rapidly release energy. The material behavior and shape changes critical to achieving rapid energy release in these systems are largely unknown due to limitations of materials testing instruments operating at high speed and large displacement. In this work, we perform fundamental, proof-of-concept measurements on the tensile retraction of elastomers. Using high speed imaging, the kinematics of retraction are measured for elastomers with varying mechanical properties and geometry. Based on the kinematics, the rate of energy dissipation in the material is determined as a function of strain and strain-rate, along with a scaling relation which describes the dependence of maximum velocity on material properties. Understanding this scaling relation along with the material failure limits of the elastomer allows the prediction of material properties required for optimal performance. We demonstrate this concept experimentally by optimizing for maximum velocity in our synthetic model system, and achieve retraction velocities that exceed those in biological impulsive systems. This model system provides a foundation for future work connecting continuum performance to molecular architecture in impulsive systems.

    The purpose of this article is to review current research investigating the reliability of bony anatomical landmark positional asymmetry assessment in the lumbar spine and pelvis, to determine the agreement on findings between authors, and to explore future directions in the area to address the significant issues. The databases MEDLINE, CINAHL, AMED, MANTIS, Academic Search Complete, and Web of Knowledge were searched. A total of 23 articles were identified and reviewed, 10 of which met the inclusion criteria. For these 10 articles, the average interexaminer reliability for bony anatomical landmark positional asymmetry assessment was slightly above chance for all landmarks except medial malleolus, which had fair reliability. Interexaminer reliability on average was less than intraexaminer reliability (anterior superior iliac spine, k = 0.128/0.414; posterior superior iliac spine, k = 0.092/0.371). All interexaminer reliability averages were below values of clinical significance. From the current literature review, bony anatomical landmark positional asymmetry assessment in the lumbar spine and pelvis has not been demonstrated to be a reliable assessment method. However, there are unexplored factors that, after standardization, may improve reliability and further the understanding of musculoskeletal palpatory examination.

    Many coral reef fish are beautifully coloured and the reflectance spectra of their colour patterns may include UVa wavelengths (315-400 nm) that are largely invisible to the human eye (Losey, G. S., Cronin, T. W., Goldsmith, T. H., David, H., Marshall, N. J., & McFarland, W.N. (1999). The uv visual world of fishes: a review. Journal of Fish Biology, 54, 921-943; Marshall, N. J. & Oberwinkler, J. (1999). The colourful world of the mantis shrimp. Nature, 401, 873-874). Before the possible functional significance of UV patterns can be investigated, it is of course essential to establish whether coral reef fishes can see ultraviolet light. As a means of tackling this question, in this study the transmittance of the ocular media of 211 coral reef fish species was measured. It was found that the ocular media of 50.2% of the examined species strongly absorb light of wavelengths below 400 nm, which makes the perception of UV in these fish very unlikely. The remaining 49.8% of the species studied possess ocular media that do transmit UV light, making the perception of UV possible.

    We present the first checklist of praying mantids (Mantodea) of Borneo, with special reference to the specimens collected during the Scientific Expedition to Lanjak Entimau Wildlife Sanctuary 2008. With 118 confirmed species in 56 genera (including subgenera), Borneo is the island with the highest mantodean diversity known to date. In Lanjak Entimau 38 specimens representing 17 genera and 18 species were collected around the station lights and in surrounding secondary and primary forest. A new synonymy in the genus Deroplatys is established. The observed diversity patterns among Bornean mantids are discussed with reference to the biogeographic history of the Sunda Shelf since the Miocene.

    We describe the tagmatization pattern of the anterior region of the extant stomatopod Erugosquilla massavensis. For documentation we used the autofluorescence capacities of the specimens, resulting in a significant contrast between sclerotized and membranous areas. The anterior body region of E. massavensis can be grouped into three tagmata. Tagma I, the sensorial unit, comprises the segments of the eyes, antennules and antennae. This unit is set-off anteriorly from the posterior head region. Ventrally this unit surrounds a large medial sclerite, interpreted as the anterior part of the hypostome. Dorsally the antennular and antennal segments each bear a well-developed tergite. The dorsal shield is part of tagma II, most of the ventral part of which is occupied in the midline by the large, partly sclerotized posterior part of a complex combining hypostome and labrum. Tagma II includes three more segments behind the labrum, the mandibular, maxillulary and maxillary segments. Tagma III includes the maxillipedal segments, bearing five pairs of sub-chelate appendages. The dorsal sclerite of the first of these tagma-III segments, the segment of the first maxillipeds, is not included in the shield, so this segment is not part of tagma II as generally thought. The second and third segments of tagma III form a unit dorsally and ventrally. The tergites of the segments of tagma III become progressively larger from the anterior to the posterior, possibly resulting from a paedomorphic effect during evolution, which caused this reversed enlargement. The described pattern of tagmosis differs from current textbook knowledge. Therefore, our re-description of the anterior body area of stomatopods is of considerable impact for understanding the head evolution of Stomatopoda. Likewise, it has a bearing upon any comparisons with fossil stomatopods, as mainly sclerotized areas are fossilized, and, on a wider scale, upon larger-scale comparisons with other malacostracans and eucrustaceans in general.

    2017-01-01

    Praying mantises are a diverse group of predatory insects. Although some Mantodea mitogenomes have been reported, a comprehensive comparative and evolutionary genomic study is lacking for this group. In the present study, four new mitogenomes were sequenced, annotated, and compared to the previously published mitogenomes of other Mantodea species. Most Mantodea mitogenomes share a typical set of mitochondrial genes and a putative control region (CR). Additionally, and most intriguingly, another large non-coding region (LNC) was detected between trnM and ND2 in all six Paramantini mitogenomes examined. The main section in this common region of Paramantini may have initially originated from the corresponding control region for each species, whereas sequence differences between the LNCs and CRs and phylogenetic analyses indicate that LNC and CR are largely independently evolving. Namely, the LNC (the duplicated CR) may have subsequently degenerated during evolution. Furthermore, evidence suggests that special intergenic gaps have been introduced in some species through gene rearrangement and duplication. These gaps are actually the original abutting sequences of migrated or duplicated genes. Some gaps (G5 and G6) are homologous to the 5' and 3' surrounding regions of the duplicated gene in the original gene order, and another specific gap (G7) has tandem repeats. We analysed the phylogenetic relationships of fifteen Mantodea species using 37 concatenated mitochondrial genes and detected several synapomorphies unique to species in some clades. PMID:28367101

    Chiropractors have long advocated on the benefits of breastfeeding and given the realized and potential role of chiropractors in the care of infants with breastfeeding difficulties, we performed this review of the literature on the subject to inform clinical practice. For this article, we searched Pubmed [1966-2013], Manual, Alternative and Natural Therapy Index System (MANTIS) [1964-2013] and Index to Chiropractic Literature [1984-2013] for the relevant literature. The search terms utilized "breastfeeding", "breast feeding", "breastfeeding difficulties", "breastfeeding difficulty", "TMJ dysfunction", "temporomandibular joint", "birth trauma" and "infants", in the appropriate Boolean combinations. We also examined non-peer-reviewed articles as revealed by Index to Chiropractic Literature and secondary analysis of references. Inclusion criteria for review included breastfeeding difficulties regardless of peer-review and written in the English language. A total of 24 articles met our inclusion criteria. These consisted of 8 case reports, 2 case series, and 3 cohort studies. We were also able to identify 6 manuscripts (5 case reports and a case series) that involved breastfeeding difficulties as a secondary complaint. Our findings reveal a theoretical and clinical framework based on the detection of spinal and extraspinal subluxations involving the cervico-cranio-mandibular complex and assessment of the infant while breastfeeding. Chiropractors care of infants with breastfeeding difficulties by addressing spinal and extraspinal subluxations involving the cervico-cranio-mandibular complex. Copyright © 2015 Elsevier Inc.

    Operating system (OS) technology is significant for the proliferation of the wireless sensor network (WSN). With an outstanding OS; the constrained WSN resources (processor; memory and energy) can be utilized efficiently. Moreover; the user application development can be served soundly. In this article; a new hybrid; real-time; memory-efficient; energy-efficient; user-friendly and fault-tolerant WSN OS MIROS is designed and implemented. MIROS implements the hybrid scheduler and the dynamic memory allocator. Real-time scheduling can thus be achieved with low memory consumption. In addition; it implements a mid-layer software EMIDE (Efficient Mid-layer Software for User-Friendly Application Development Environment) to decouple the WSN application from the low-level system. The application programming process can consequently be simplified and the application reprogramming performance improved. Moreover; it combines both the software and the multi-core hardware techniques to conserve the energy resources; improve the node reliability; as well as achieve a new debugging method. To evaluate the performance of MIROS; it is compared with the other WSN OSes (TinyOS; Contiki; SOS; openWSN and mantisOS) from different OS concerns. The final evaluation results prove that MIROS is suitable to be used even on the tight resource-constrained WSN nodes. It can support the real-time WSN applications. Furthermore; it is energy efficient; user friendly and fault tolerant. PMID:25248069

    1994-10-15

    Electromagnetic field calculations for radio frequency (rf) antennas in two dimensions (2-D) neglect finite antenna length effects as well as the feeders leading to the main current strap. The 2-D calculations predict that the return currents in the sidewalls of the antenna structure depend strongly on the plasma parameters, but this prediction is suspect because of experimental evidence. To study the validity of the 2-D approximation, the Multiple Antenna Implementation System (MAntIS) has been used to perform three-dimensional (3-D) modeling of the power spectrum, plasma loading, and inductance for a relevant loop antenna design. Effects on antenna performance caused bymore » feeders to the main current strap and conducting sidewalls are considered. The modeling shows that the feeders affect the launched power spectrum in an indirect way by forcing the driven rf current to return in the antenna structure rather than the plasma, as in the 2-D model. It has also been found that poloidal dependencies in the plasma impedance matrix can reduce the loading predicted from that predicted in the 2-D model. For some plasma parameters, the combined 3-D effects can lead to a reduction in the predicted loading by as much as a factor of 2 from that given by the 2-D model, even with end-effect corrections for the 2-D model.« less

    Up to energies of 140 keV neutral beam injection (NBI) based on positive ions has proven to be a reliable and flexible plasma heating method and has provided major contributions to most of the important experiments on virtually all large tokamaks around the world. As a candidate for additional heating and current drive on next step fusion machines (ITER ao) it is hoped that NBI can be equally successful. The ITER NBI parameters of 1 MeV, 50 MW D{degree} demand primary D{sup {minus}} beams with current densities of at least 15 mA/cm{sup 2}. Although considerable progress has been made inmore » the area of negative ion production and acceleration the high demands still require substantial and urgent development. Regarding negative ion production Cs seeded plasma sources lead the way. Adding a small amount of Cs to the discharge (Cs seeding) not only increases the negative ion yield by a factor 3--5 but also has the advantage that the discharge can be run at lower pressures. This is beneficial for the reduction of stripping losses in the accelerator. Multi-ampere negative ion production in a large plasma source is studied in the MANTIS experiment. Acceleration and neutralization at ITER relevant parameters is the objective of the 1 MV SINGAP experiment.« less

    Operating system (OS) technology is significant for the proliferation of the wireless sensor network (WSN). With an outstanding OS; the constrained WSN resources (processor; memory and energy) can be utilized efficiently. Moreover; the user application development can be served soundly. In this article; a new hybrid; real-time; memory-efficient; energy-efficient; user-friendly and fault-tolerant WSN OS MIROS is designed and implemented. MIROS implements the hybrid scheduler and the dynamic memory allocator. Real-time scheduling can thus be achieved with low memory consumption. In addition; it implements a mid-layer software EMIDE (Efficient Mid-layer Software for User-Friendly Application Development Environment) to decouple the WSN application from the low-level system. The application programming process can consequently be simplified and the application reprogramming performance improved. Moreover; it combines both the software and the multi-core hardware techniques to conserve the energy resources; improve the node reliability; as well as achieve a new debugging method. To evaluate the performance of MIROS; it is compared with the other WSN OSes (TinyOS; Contiki; SOS; openWSN and mantisOS) from different OS concerns. The final evaluation results prove that MIROS is suitable to be used even on the tight resource-constrained WSN nodes. It can support the real-time WSN applications. Furthermore; it is energy efficient; user friendly and fault tolerant.

    Nowadays, the use of mathematical models and computer simulation allow analysis of many different technological solutions as well as testing various scenarios in a short time and at low financial budget in order to simulate the scenario under typical conditions for the real system and help to find the best solution in design or operation process. The aim of the study was to evaluate different concepts of biochemical processes and energy balance modelling using a simulation platform GPS-x and a comprehensive model Mantis2. The paper presents the example of calibration and validation processes in the biological reactor as well as scenarios showing an influence of operational parameters on the WWTP energy balance. The results of batch tests and full-scale campaign obtained in the former work were used to predict biochemical and operational parameters in a newly developed plant model. The model was extended with sludge treatment devices, including anaerobic digester. Primary sludge removal efficiency was found as a significant factor determining biogas production and further renewable energy production in cogeneration. Water and wastewater utilities, which run and control WWTP, are interested in optimizing the process in order to save environment, their budget and decrease the pollutant emissions to water and air. In this context, computer simulation can be the easiest and very useful tool to improve the efficiency without interfering in the actual process performance.

    To conduct a descriptive review of the scientific literature examining use rates of modalities and procedures used by CAM clinicians to manage chronic LBP and other conditions A literature of PubMed and MANTIS was performed using the key terms Chiropractic; Low Back Pain; Utilization Rate; Use Rate; Complementary and Alternative Medicine; and Health Services in various combinations. A total of 137 papers were selected, based upon including information about chiropractic utilization, CAM utilization and low back pain and other conditions. Information was extracted from each paper addressing use of chiropractic and CAM, and is summarized in tabular form. Thematic analysis of the paper topics indicated that there were 5 functional areas covered by the literature: back pain papers, general chiropractic papers, insurance-related papers, general CAM-related papers; and worker's compensation papers. Studies looking at chiropractic utilization demonstrate that the rates vary, but generally fall into a range from around 6% to 12% of the population, most of whom seek chiropractic care for low back pain and not for organic disease or visceral dysfunction. CAM is itself used by people suffering from a variety of conditions, though it is often used not as a primary intervention, but rather as an additional form of care. CAM and chiropractic often offer lower costs for comparable results compared to conventional medicine.

    Cancer is the leading cause of death worldwide and accounted for 7.4 million deaths in 2004. By 2030, deaths from cancer have been estimated at 12 million with 30% being preventable. Complementary and alternative medicine remains popular among cancer patients; particularly with chiropractic services. However, the nature of the chiropractic clinical encounter and its reported benefits remains to be fully investigated. Towards these efforts, we begin with a systematic review of the literature on the chiropractic care of patients with cancer. The following electronic databases were searched: MANTIS [1965-2010]; Index to Chiropractic Literature [1984-2010]; Pubmed [1966-2010]; Medline [1965-2010] EMBASE [1974-2010], AMED [1975-2010], CINAHL Plus [1965-2010], Alt-Health Watch [1965-2010] and PsychINFO [1965-2010]. Key words used were "cancer" and "neoplasm" in Boolean combination with "chiropractic." Primary investigation/reports in peer-reviewed English journals involving chiropractic care were reviewed. Our review revealed 60 case reports, 2 case series, 21 commentaries, 2 survey studies, and 2 literature reviews. The case reports were diagnostic with commentaries highlighting the importance of recognizing the patient presenting with NMS complaints due to an underlying neoplasm. The chiropractic clinical encounter prior to cancer diagnosis and subsequent medical referral is poorly characterized in the literature. Patients with cancer seek the care of chiropractors. The literature does not reflect or describe the totality of the chiropractic clinical encounter. We encourage further research in this field.

  14. Comparative investigations into the feeding ecology of six Mantodea species.

    Six mantid species (Sphodromantis viridis, Polyspilota aeruginosa, Hierodula unimaculata, Parasphendale agrionia, Mantis religiosa and Empusa pennata) were studied in laboratory feeding experiments. Mantids stalk their prey and pounce on it, grasping it with their forelegs. Only living prey is selected and it is consumed directly after the catch. The predator orients itself optically, and therefore only takes notice of moving prey. The maximum size of prey which mantids can overwhelm is species-specific and depends on the prey type. On average mantids eat crickets of 50% their own body-weight while cockroaches can weigh up to 110%. Feeding experiments with 101 species of potential prey of 21 invertebrate orders showed an average feeding rate of 70% and marked differences among the predators. Polyspilota proved to be the least specialized mantid and Empusa caught the smallest amount of prey. Most of the defence mechanisms which arthropods have developed against their enemies proved to be ineffective against mantids. Neither a hard chitinous exoskeleton nor poisonous substances prevented the mantids from attacking their prey successfully. The protective secretion of the cotton stainer Dysdercus intermedius proved to be effective at least in a few instances. Even though these bugs were killed, the mantids usually refused to eat the abdomen, where the glands that produce the protective secretion are to be found. Thanatosis, as exhibited by the chrysomelid Cassida viridis and by the phasmid Carausius morosus, proved to be the best protection against mantids.

    Models of the evolution of sexual cannibalism show that the frequency of male mating opportunities has significant impact on male choice and male risk aversion. In this study, we examined ecological components that should affect opportunities for multiple mating in wild populations of the Chinese mantid (Tenodera sinensis Saussure). While conducting mark-recapture studies of two field populations over the course of two seasons, along with Global Positioning System data on locations of individuals, we collected data on population densities, movement patterns, and individual ranges to estimate the overlap of adult males and female mantids. Our results show that local populations of mantids range from 89 to 161 individuals and occur at densities ranging from 10 to 39 mantids per 1,000 m2. Males move greater distances daily compared with females, giving males larger home range sizes. The ranges of male mantids overlapped with multiple females, thus offering the potential for multiple mating by males. We directly observed 11 encounters between male and female T. sinensis, including one multiple mating by an individual male. The overall mate encounter rate for males was 12.5%. We also provide additional observations of interspecific sexual attraction between T. sinensis and Mantis religiosa Linne (Mantodea: Mantidae). Mantids were most commonly found within the top 20% of two flowering plants, goldenrod (Solidago Linnaeus spp. (Asterales: Asteraceae)) and mugwort (Artemisia vulgaris Linnaeus (Asterales: Asteraceae)), which should place them in prime locations for capturing flying pollinators.

    We used functional magnetic resonance imaging (fMRI) to investigate how performing formalized and improvised forms of praying changed the evoked BOLD response in a group of Danish Christians. Distinct from formalized praying and secular controls, improvised praying activated a strong response in the temporopolar region, the medial prefrontal cortex, the temporo-parietal junction and precuneus. This finding supports our hypothesis that religious subjects, who consider their God to be 'real' and capable of reciprocating requests, recruit areas of social cognition when they pray. We argue that praying to God is an intersubjective experience comparable to 'normal' interpersonal interaction.

    Microsatellite instability (MSI) is a pattern of hypermutation that occurs at genomic microsatellites and is caused by defects in the mismatch repair system. Mismatch repair deficiency that leads to MSI has been well described in several types of human cancer, most frequently in colorectal, endometrial, and gastric adenocarcinomas. MSI is known to be both predictive and prognostic, especially in colorectal cancer; however, current clinical guidelines only recommend MSI testing for colorectal and endometrial cancers. Therefore, less is known about the prevalence and extent of MSI among other types of cancer. Using our recently published MSI-calling software, MANTIS, we analyzed whole-exome data from 11,139 tumor-normal pairs from The Cancer Genome Atlas and Therapeutically Applicable Research to Generate Effective Treatments projects and external data sources across 39 cancer types. Within a subset of these cancer types, we assessed mutation burden, mutational signatures, and somatic variants associated with MSI. We identified MSI in 3.8% of all cancers assessed-present in 27 of tumor types-most notably adrenocortical carcinoma (ACC), cervical cancer (CESC), and mesothelioma, in which MSI has not yet been well described. In addition, MSI-high ACC and CESC tumors were observed to have a higher average mutational burden than microsatellite-stable ACC and CESC tumors. We provide evidence of as-yet-unappreciated MSI in several types of cancer. These findings support an expanded role for clinical MSI testing across multiple cancer types as patients with MSI-positive tumors are predicted to benefit from novel immunotherapies in clinical trials.

    BACKGROUND Although practice protocols exist for SMT and functional rehabilitation, no practice protocols exist for structural rehabilitation. Traditional chiropractic practice guidelines have been limited to acute and chronic pain treatment, with limited inclusion of functional and exclusion of structural rehabilitation procedures. OBJECTIVE (1) To derive an evidence-based practice protocol for structural rehabilitation from publications on Clinical Biomechanics of Posture (CBP®) methods, and (2) to compare the evidence for Diversified, SMT, and CBP®. METHODS Clinical control trials utilizing CBP® methods and spinal manipulative therapy (SMT) were obtained from searches in Mantis, CINAHL, and Index Medicus. Using data from SMT review articles, evidence for Diversified Technique (as taught in chiropractic colleges), SMT, and CBP® were rated and compared. RESULTS From the evidence from Clinical Control Trials on SMT and CBP®, there is very little evidence support for Diversified (our rating = 18), as taught in chiropractic colleges, for the treatment of pain subjects, while CBP® (our rating = 46) and SMT for neck pain (rating = 58) and low back pain (our rating = 202) have evidence-based support. CONCLUSIONS While CBP® Technique has approximately as much evidence-based support as SMT for neck pain, CBP® has more evidence to support its methods than the Diversified technique taught in chiropractic colleges, but not as much as SMT for low back pain. The evolution of chiropractic specialization has occurred, and doctors providing structural-based chiropractic care require protocol guidelines for patient quality assurance and standardization. A structural rehabilitation protocol was developed based on evidence from CBP® publications. PMID:17549209

    Background Stomach contents of 131 specimens of five elasmobranch species (Mustelus lunulatus, Dasyatis longa, Rhinobatos leucorhynchus, Raja velezi and Zapteryx xyster) caught in the central fishing zone in the Pacific Ocean of Colombia were counted and weighed to describe feeding habits and dietary overlaps. Results Twenty-one prey items belonging to four major groups (stomatopods, decapods, mollusks and fish) were identified. Decapod crustaceans were the most abundant prey found in stomachs. The mantis shrimp Squilla panamensis was the main prey item in the diet of M. lunulatus; tiger shrimp Trachypenaeus sp. was the main prey item in the diet of Rhinobatos leucorhynchus and Raja velezi, and Penaeidae shrimp were the main prey items in the diet of Z. xyster. Furthermore, fish were important in the diet of Raja velezi, Z. xyster and D. longa. The greatest diet breadth corresponded to Z. xyster whereas M. lunulatus was the most specialized predator. Finally, four significant diet overlaps between the five species were found, attributable mainly to Squillidae, Penaeidae and Fish. Conclusion Shrimps (Penaeidae and stomatopods) and benthic fishes were the most important food types in the diet of the elasmobranch species studied. Diet breadth and overlap were relatively low. Determination of food resource partitioning among the batoid species studied was not possible. However, we identified partitions in other niche axes (time of feeding activity and habitat utilization). It is possible to assume that diffuse competition could be exceeding the biunivocal competition among the studied species. Therefore, this assemblage would have a strong tendency to trophic guild formation. PMID:17877796

    The objective of this review is to establish the current state of knowledge on the reliability of clinical assessment of asymmetry in the lumbar spine and pelvis. To search the literature, the authors consulted the databases of MEDLINE, CINAHL, AMED, MANTIS, Academic Search Complete, and Web of Knowledge using different combinations of the following keywords: palpation, asymmetry, inter or intraexaminer reliability, tissue texture, assessment, and anatomic landmark. Of the 23 studies identified, 14 did not meet the inclusion criteria and were excluded. The quality and methods of studies investigating the reliability of bony anatomic landmark asymmetry assessment are variable. The κ statistic ranges without training for interexaminer reliability were as follows: anterior superior iliac spine (ASIS), -0.01 to 0.19; posterior superior iliac spine (PSIS), 0.04 to 0.15; inferior lateral angle, transverse plane (ILA-A/P), -0.03 to 0.11; inferior lateral angles, coronal plane (ILA-S/I), -0.01 to 0.08; sacral sulcus (SS), -0.4 to 0.37; lumbar spine transverse processes L1 through L5, 0.04 to 0.17. The corresponding ranges for intraexaminer reliability were higher for all associated landmarks: ASIS, 0.19 to 0.4; PSIS, 0.13 to 0.49; ILA-A/P, 0.1 to 0.2; ILA-S/I, 0.03 to 0.21; SS, 0.24 to 0.28; lumbar spine transverse processes L1 through L5, not applicable. Further research is needed to better understand the reliability of asymmetry assessment methods in manipulative medicine.

    Maternal polycystic ovary syndrome (PCOS), a condition associated with hyperandrogenism, is suggested to increase anxiety-like behavior in the offspring. Because PCOS is closely linked to obesity, we investigated the impact of an adverse hormonal or metabolic maternal environment and offspring obesity on anxiety in the offspring. The obese PCOS phenotype was induced by chronic high-fat-high-sucrose (HFHS) consumption together with prenatal dihydrotestosterone exposure in mouse dams. Anxiety-like behavior was assessed in adult offspring with the elevated-plus maze and open-field tests. The influence of maternal androgens and maternal and offspring diet on genes implicated in anxiety were analyzed in the amygdala and hypothalamus with real-time PCR ( n = 47). Independent of diet, female offspring exposed to maternal androgens were more anxious and displayed up-regulation of adrenoceptor α 1B in the amygdala and up-regulation of hypothalamic corticotropin-releasing hormone ( Crh). By contrast, male offspring exposed to a HFHS maternal diet had increased anxiety-like behavior and showed up-regulation of epigenetic markers in the amygdala and up-regulation of hypothalamic Crh. Overall, there were substantial sex differences in gene expression in the brain. These findings provide novel insight into how maternal androgens and obesity exert sex-specific effects on behavior and gene expression in the offspring of a PCOS mouse model.-Manti, M., Fornes, R., Qi, X., Folmerz, E., Lindén Hirschberg, A., de Castro Barbosa, T., Maliqueo, M., Benrick, A., Stener-Victorin, E.

    Spiritual elements play an important role in the recovery process from acute postoperative pain. This study was conducted to assess the effect of pray meditation on postoperative pain reduction and physiologic responds among muslim patients who underwent cesarean surgery under spinal anesthesia. This double-blinded randomized clinical trial study was conducted among muslim patients who underwent cesarean surgery under spinal anesthesia during 2011-2013 at tertiary regional and teaching hospital in Lorestan, Iran. The patients were randomly divided into interventional group (n=80) and control group (n=80). For about 20 minutes using a disposable phone mentioned and listened to pray meditation "Ya man esmoho davaa va zekroho shafa, Allahomma salle ala mohammad va ale mohammad" in interventional group and phone off in control group. Before and during pray meditation, 30, 60 minutes, 3 and 6 hours after pray meditation pain intensity, blood pressure, heart rate and respiratory rate were measured. No statistically significant improvement in pain score was found before and during pray meditation, 30, 60 minutes after pray meditation (P>0.05). Statistically significant improvement in pain score was found at 3 and 6 hours after pray meditation than control group (1.5 ± 0.3 vs. 3 ± 1.3, P=0.030) and (1.3 ± 0.8 vs. 3 ± 1.1, P=0.003). However, there was no significant difference in the physiological responses (systolic and diastolic blood pressure, respiration, and heart rate) any time between the groups. Religion and spirituality intervention such as pray meditation could be used as one of non-pharmacological pain management techniques for reducing pain after cesarean surgery. Also, Pray meditation provides less postoperative nausea and vomiting (PONV) and more relaxation.

    Multiple methods were used to examine children's awareness of connections between emotion and prayer. Four-, 6-, and 8-year-olds and adults (N = 100) predicted whether people would pray when feeling different emotions, explained why characters in different situations decided to pray, and predicted whether characters' emotions would change after praying. Four- and 6-year-olds exclusively judged that positive emotions motivate prayer, whereas 8-year-olds and adults most often predicted that negative emotions would cause people to pray and that praying could improve emotions. There was also a significant increase between 4 and 8 years in explaining prayer as motivated by need for assistance, for thanksgiving, and for conversation, as well as for explaining postprayer emotions in relation to God or prayer. Religious background predicted individual differences in reasoning only for 4-year-olds. Copyright 2009 APA, all rights reserved.

    Novel stimuli elicit behaviors that are collectively known as specific exploration. These behaviors allow the animal to become more familiar with the novel objects within its environment. Specific exploration is frequently suppressed by defensive reactions to predator cues. Herein, we examine if this suppression occurs in Drosophila melanogaster by measuring the response of these flies to wild harvested predators. The flies used in our experiments have been cultured and had not lived under predator threat for multiple decades. In a circular arena with centrally-caged predators, wild type Drosophila actively avoided the pantropical jumping spider, Plexippus paykulli, and the Texas unicorn mantis, Phyllovates chlorophaena, indicating an innate defensive reaction to these predators. Interestingly, wild type Drosophila males also avoided a centrally-caged mock spider, and the avoidance of the mock spider became exaggerated when it was made to move within the cage. Visually impaired Drosophila failed to detect and avoid the Plexippus paykulli and the moving mock spider, while the broadly anosmic orco2 mutants were fully capable of detecting and avoiding Plexippus paykulli, indicating that these flies principally relied upon vison to perceive the predator stimuli. During early exploration of the arena, exploratory activity increased in the presence of Plexippus paykulli and the moving mock spider. The elevated activity induced by Plexippus paykulli disappeared after the fly had finished exploring, suggesting the flies were capable of habituating the predator cues. Taken together, these results indicate that despite being isolated from predators for decades Drosophila will visually detect these predators, retain innate defensive behaviors, respond by increasing exploratory activity in the arena rather than suppressing activity, and may habituate to normal predator cues.

    Purpose: The Journal of Chiropractic Education celebrates its 25th anniversary in the year 2011. The purpose of this article is to chronicle the history of the journal, which is unreported at this time. Methods: The entire collection of the journal was reviewed and information pertaining to important events and changes in the format, personnel, and processes of the journal were extracted. This information was used to create a chronology of the journal. The chronology was complemented with information obtained from people who were involved in the evolution of the journal and the Association of Chiropractic Colleges Educational Conferences. Results: Starting as a humble newsletter in 1987 and produced for a small cadre of readers primarily from the United States, the journal is now a full-sized and bound peer-reviewed international journal. Initially cataloged by the Index to Chiropractic Literature and MANTIS, the indexing expanded to interdisciplinary indexing systems such as CINAHL and ultimately PubMed. The journal has grown to serve the needs of chiropractic educators from around the world with representatives on the editorial board from 39 colleges and universities from 15 different countries. The journal has grown in tandem with the profession’s leading education and research conference and has been the primary repository for the scholarship of chiropractic education. Conclusion: The history of the journal represents a significant milestone in the development of the chiropractic profession, particularly the discipline of chiropractic education. The journal has had an interesting history and the future promises to bring more opportunities and challenges to the field of chiropractic education and to the journal. PMID:22069342

    Sharma, D; Badano, A; Sempau, J

    Purpose: Variance reduction techniques (VRTs) are employed in Monte Carlo simulations to obtain estimates with reduced statistical uncertainty for a given simulation time. In this work, we study the bias and efficiency of a VRT for estimating the response of imaging detectors. Methods: We implemented Directed Sampling (DS), preferentially directing a fraction of emitted optical photons directly towards the detector by altering the isotropic model. The weight of each optical photon is appropriately modified to maintain simulation estimates unbiased. We use a Monte Carlo tool called fastDETECT2 (part of the hybridMANTIS open-source package) for optical transport, modified for VRT. Themore » weight of each photon is calculated as the ratio of original probability (no VRT) and the new probability for a particular direction. For our analysis of bias and efficiency, we use pulse height spectra, point response functions, and Swank factors. We obtain results for a variety of cases including analog (no VRT, isotropic distribution), and DS with 0.2 and 0.8 optical photons directed towards the sensor plane. We used 10,000, 25-keV primaries. Results: The Swank factor for all cases in our simplified model converged fast (within the first 100 primaries) to a stable value of 0.9. The root mean square error per pixel for DS VRT for the point response function between analog and VRT cases was approximately 5e-4. Conclusion: Our preliminary results suggest that DS VRT does not affect the estimate of the mean for the Swank factor. Our findings indicate that it may be possible to design VRTs for imaging detector simulations to increase computational efficiency without introducing bias.« less

    The purpose of this study was to systematically review studies that quantify the high-velocity, low-amplitude (HVLA) spinal thrust, to qualitatively compare the apparatus used and the force-time profiles generated, and to critically appraise studies involving the quantification of thrust as an augmented feedback tool in psychomotor learning. A search of the literature was conducted to identify the sources that reported quantification of the HVLA spinal thrust. MEDLINE-OVID (1966-present), MANTIS-OVID (1950-present), and CINAHL-EBSCO host (1981-present) were searched. Eligibility criteria included that thrust subjects were human, animal, or manikin and that the thrust type was a hand-delivered HVLA spinal thrust. Data recorded were single force, force-time, or displacement-time histories. Publications were in English language and after 1980. The relatively small number of studies, combined with the diversity of method and data interpretation, did not enable meta-analysis. Twenty-seven studies met eligibility criteria: 17 studies measured thrust as a primary outcome (13 human, 2 cadaver, and 2 porcine). Ten studies demonstrated changes in psychomotor learning related to quantified thrust data on human, manikin, or other device. Quantifiable parameters of the HVLA spinal thrust exist and have been described. There remain a number of variables in recording that prevent a standardized kinematic description of HVLA spinal manipulative therapy. Despite differences in data between studies, a relationship between preload, peak force, and thrust duration was evident. Psychomotor learning outcomes were enhanced by the application of thrust data as an augmented feedback tool. Copyright © 2010 National University of Health Sciences. Published by Mosby, Inc.

  11. Mitochondrial genomes suggest that hexapods and crustaceans are mutually paraphyletic

    2005-01-01

    For over a century the relationships between the four major groups of the phylum Arthropoda (Chelicerata, Crustacea, Hexapoda and Myriapoda) have been debated. Recent molecular evidence has confirmed a close relationship between the Crustacea and the Hexapoda, and has included the suggestion of a paraphyletic Hexapoda. To test this hypothesis we have sequenced the complete or near-complete mitochondrial genomes of three crustaceans (Parhyale hawaiensis, Squilla mantis and Triops longicaudatus), two collembolans (Onychiurus orientalis and Podura aquatica) and the insect Thermobia domestica. We observed rearrangement of transfer RNA genes only in O. orientalis, P. aquatica and P. hawaiensis. Of these, only the rearrangement in O. orientalis, an apparent autapomorphy for the collembolan family Onychiuridae, was phylogenetically informative. We aligned the nuclear and amino acid sequences from the mitochondrial protein-encoding genes of these taxa with their homologues from other arthropod taxa for phylogenetic analysis. Our dataset contains many more Crustacea than previous molecular phylogenetic analyses of the arthropods. Neighbour-joining, maximum-likelihood and Bayesian posterior probabilities all suggest that crustaceans and hexapods are mutually paraphyletic. A crustacean clade of Malacostraca and Branchiopoda emerges as sister to the Insecta sensu stricto and the Collembola group with the maxillopod crustaceans. Some, but not all, analyses strongly support this mutual paraphyly but statistical tests do not reject the null hypotheses of a monophyletic Hexapoda or a monophyletic Crustacea. The dual monophyly of the Hexapoda and Crustacea has rarely been questioned in recent years but the idea of both groups' paraphyly dates back to the nineteenth century. We suggest that the mutual paraphyly of both groups should seriously be considered. PMID:16024395

  12. To pray or not to pray: a question of ethics.

    PubMed

    French, Charlotte; Narayanasamy, Aru

    There is a widespread belief that nurses have a duty to provide spiritual care. However, many feel there is still a need for debate surrounding the ethical use of prayer in both nursing research and practice. By using critical reflections and evidence-based literature, this paper develops a discourse on the ethics of prayer as a spiritual intervention in nursing and health care practice. Several key ethical issues are highlighted. In regards to research, lack of informed consent is a major concern in both research and nursing practice. Key ethical issues in practice include questions around intention and authority, e.g. despite the religious beliefs of the nurse, intentions to proselytize must be avoided to protect patient autonomy and avoid abuse of the nurse's authority. Furthermore, prayer has unknown side effects and implications. This paper concludes that, in practice, nurses must reconcile their personal, spiritual beliefs with their professional duties, and while this may be a delicate balance, it is not yet appropriate to encourage or dissuade a patient from their beliefs until appropriate research evidence is produced.

    Objectives Prayer is becoming more widely acknowledged as a way to cope with cancer. The goal of this study was to compare differences in use of prayer between breast cancer survivors from different ethnic groups and examine how use of prayer is related to mood and quality of life. Methods This study used a mixed methods design. One hundred and seventy-five breast cancer survivors participated in a longitudinal study of survivorship. Women completed in-depth qualitative interviews and a battery of measures including quality of life, spirituality, social support, and mood. Results Eighty-one percent of the women prayed. There were no significant differences between the groups for any of the psychological, social support, or quality of life variables with the exception of higher benefit finding and spiritual well-being among those who prayed. The data did show that women who prayed were able to find more positive contributions from their cancer experience than women who did not pray. The interviews showed that those who prayed tended to be African American or Asian, Catholic or Protestant. The prayers were for petitioning, comfort, or praise. Some of the women stated that they had difficulty praying for themselves. Conclusions While there seems to be few differences in terms of standardized measures of quality of life, social support, and mood between those who prayed and those who did not, the interviews showed that certain ethnic minority groups seem to find more comfort in prayer, felt closer to God, and felt more compassion and forgiveness than Caucasian women.

    Background and Objectives Prayer for health (PFH) is common; in 2002, 35% of US adults prayed for their health. We examined the relationship of PFH and primary care visits, with a special focus on African American women, using data from the 2002 National Health Interview Survey (NHIS). Methods We used chi-square analyses to compare the demographic (age group, gender, race, region, marital status, educational level, ethnicity) and health-related covariates (alcohol use, smoking status, and selected medical conditions) between individuals who did and did not pray for their health in the past year. Univariate associations between PFH and visit to primary care provider (PCP), with Mantel-Haenszel adjustment for confounding, were determined. Multivariate regression was used to determine independent factors associated with PFH and PCP visit, with SUDAAN to adjust for the clustered survey design. Results Subjects who prayed were more likely to be female, older than 58, Black, Southern, separated, divorced or widowed, and nondrinkers. Subjects who prayed were also more likely to have seen a PCP within the past year. Black women who prayed were also more likely to see a PCP. Conclusions These findings suggest that people who pray for their health do so in addition to, not instead of, seeking primary care. This finding is maintained but with a smaller effect size, in Black women. PMID:18830839

    The purposes of this study were to (1) determine whether sagittal spinal curves are associated with health in epidemiological studies, (2) estimate the strength of such associations, and (3) consider whether these relations are likely to be causal. A systematic critical literature review of epidemiological (cross-sectional, case-control, cohort) studies published before 2008 including studies identified in the CINAHL, EMBASE, Mantis, and Medline databases was performed using a structured checklist and a quality assessment. Level of evidence analysis was performed as outlined by van Tulder et al (Spine. 2003;28:1290-9), and the strength of associations were determined using the procedure outlined by Hemingway and Marmot (BMJ. 1999;318:1460-7). Quality of the included articles were assessed by our own scoring system based on the STrengthening the Reporting of OBservational studies in Epidemiology checklist. Studies scoring maximum points (4/4 or 3/3) were considered to be of higher quality. Fifty-four original studies were included. We found no strong evidence for any association between sagittal spinal curves and any health outcomes including spinal pain. The included studies were generally of low methodological quality. There is moderate evidence for association between sagittal spinal curves and 4 health outcomes as follows: temporomandibular disorders (no odds ratios [ORs] provided), pelvic organ prolapse (OR, 3.18; 95% confidence interval [CI], 1.46-96.93), daily function (OR range, 1.8-3.7; 95% CI range, 1.1-6.3), and death (OR, 1.40; 95% CI, 1.08-1.91). These associations are however unlikely to be causal. Evidence from epidemiological studies does not support an association between sagittal spinal curves and health including spinal pain. Further research of better methodological quality may affect this conclusion, and causal effects cannot be determined in a systematic review.

    Neutral beam injection (NBI) is one of the candidates for plasma heating and current drive in the new generation of large magnetic fusion devices (ITER). In order to produce the required deuterium atom beams with energies of 1 MeV and powers of tens of MW, negative D{sup {minus}} ion beams are required. For this purpose, multiampere D{sup {minus}} beam production and 1 MeV electrostatic acceleration is being studied at Cadarache. The SINGAP experiment, a 1 MeV 0.1 A D{sup {minus}} multisecond beam accelerator facility, has recently started operation. It is equipped with a Pagoda ion source, a multiaperture 60 keVmore » preaccelerator and a 1 MV 120 mA power supply. The particular feature of SINGAP is that the postaccelerator merges the 60 keV beamlets, aiming at accelerating the whole beam to 1 MeV in a single gap. The 1 MV level was obtained in less than 2 weeks, the accumulated voltage on-time of being {approximately}22 min. A second test bed MANTIS, is devoted to the development of multiampere D{sup {minus}} sources. It is capable of driving discharges with current up to 2500 A at arc voltages up to 150 V. A large multicusp source has been tested in pure volume and cesiated operation. With cesium seeding, an accelerated D{sup {minus}} beam current density of up to 5.2 mA/cm{sup 2} (2 A of D{sup {minus}}) was obtained. A modification of the extractor is underway in order to improve this performance. A 3D Monte Carlo code has been developed to simulate the negative ion transport in magnetized plasma sources and optimize magnetic field configuration of the large area D{sup {minus}} sources. {copyright} {ital 1996 American Institute of Physics.}« less

    1993-09-01

    Electromagnetic field calculations for radio frequency (rf) antennas in two dimensions (2-D) neglect finite antenna length effects as well as the feeders leading to the main current strap. Comparisons with experiments indicate that these 2-D calculations can overestimate the loading of the antenna and fail to give the correct reactive behavior. To study the validity of the 2-D approximation, the Multiple Antenna Implementation System (MAntIS) has been used to perform 3-D modeling of the power spectrum, plasma loading, and inductance for a relevant loop antenna design. Effects on antenna performance caused by feeders to the main current strap, conducting sidewalls,more » and finite phase velocity are considered. The plasma impedance matrix for the loading calculation is generated by use of the ORION-1D code. The 3-D model is benchmarked with the 2-D model in the 2-D limit. For finite-length antennas, inductance calculations are found to be in much more reasonable agreement with experiments for 3-D modeling than for the 2-D estimates. The modeling shows that the feeders affect the launched power spectrum in an indirect way by forcing the driven rf current to return in the antenna sidewalls rather than in the plasma as in the 2-D model. Thus, the feeders have much more influence than the plasma on the currents that return in the sidewall. It has also been found that poloidal dependencies in the plasma impedance matrix can reduce the loading from that predicted in the 2-D model. For some plasma parameters, the combined 3-D effects can lead to a reduction in the predicted loading by as much as a factor of 2 from that given by the 2-D model.« less

    Image quality in thick scintillator detectors can be improved by minimizing parallax errors through depth-of-interaction (DOI) estimation. A novel sensor for low-energy single photon imaging having a thick, transparent, crystalline pixelated micro-columnar CsI:Tl scintillator structure has been described, with possible future application in small-animal single photon emission computed tomography (SPECT) imaging when using thicker structures under development. In order to understand the fundamental limits of this new structure, we introduce cartesianDETECT2, an open-source optical transport package that uses Monte Carlo methods to obtain estimates of DOI for improving spatial resolution of nuclear imaging applications. Optical photon paths are calculated as a function of varying simulation parameters such as columnar surface roughness, bulk, and top-surface absorption. We use scanning electron microscope images to estimate appropriate surface roughness coefficients. Simulation results are analyzed to model and establish patterns between DOI and photon scattering. The effect of varying starting locations of optical photons on the spatial response is studied. Bulk and top-surface absorption fractions were varied to investigate their effect on spatial response as a function of DOI. We investigated the accuracy of our DOI estimation model for a particular screen with various training and testing sets, and for all cases the percent error between the estimated and actual DOI over the majority of the detector thickness was ±5% with a maximum error of up to ±10% at deeper DOIs. In addition, we found that cartesianDETECT2 is computationally five times more efficient than MANTIS. Findings indicate that DOI estimates can be extracted from a double-Gaussian model of the detector response. We observed that our model predicts DOI in pixelated scintillator detectors reasonably well.

    Manual therapy is the non-surgical conservative management of musculoskeletal disorders using the practitioner's hands on the patient's body for diagnosing and treating disease. The aim of this study is to systematically review trial-based economic evaluations of manual therapy relative to other interventions used for the management of musculoskeletal diseases. Randomised clinical trials (RCTs) on the economic evaluation of manual therapy for musculoskeletal diseases will be included in the review. The following databases will be searched from their inception: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Econlit, Mantis, Index to Chiropractic Literature, Science Citation Index, Social Science Citation Index, Allied and Complementary Medicine Database (AMED), Cochrane Database of Systematic Reviews (CDSR), National Health Service Database of Abstracts of Reviews of Effects (NHS DARE), National Health Service Health Technology Assessment Database (NHS HTA), National Health Service Economic Evaluation Database (NHS EED), CENTRAL, five Korean medical databases (Oriental Medicine Advanced Searching Integrated System (OASIS), Research Information Service System (RISS), DBPIA, Korean Traditional Knowledge Portal (KTKP) and KoreaMed) and three Chinese databases (China National Knowledge Infrastructure (CNKI), VIP and Wanfang). The evidence for the cost-effectiveness, cost-utility and cost-benefit of manual therapy for musculoskeletal diseases will be assessed as the primary outcome. Health-related quality of life and adverse effects will be assessed as secondary outcomes. We will critically appraise the included studies using the Cochrane risk of bias tool and the Drummond checklist. Results will be summarised using Slavin's qualitative best-evidence synthesis approach. The results of the study will be disseminated via a peer-reviewed journal and/or conference presentations

    When conducting systematic reviews, it is essential to perform a comprehensive literature search to identify all published studies relevant to the specific research question. The Cochrane Collaborations Methodological Expectations of Cochrane Intervention Reviews (MECIR) guidelines state that searching MEDLINE, EMBASE and CENTRAL should be considered mandatory. The aim of this study was to evaluate the MECIR recommendations to use MEDLINE, EMBASE and CENTRAL combined, and examine the yield of using these to find randomized controlled trials (RCTs) within the area of musculoskeletal disorders. Data sources were systematic reviews published by the Cochrane Musculoskeletal Review Group, including at least five RCTs, reporting a search history, searching MEDLINE, EMBASE, CENTRAL, and adding reference- and hand-searching. Additional databases were deemed eligible if they indexed RCTs, were in English and used in more than three of the systematic reviews. Relative recall was calculated as the number of studies identified by the literature search divided by the number of eligible studies i.e. included studies in the individual systematic reviews. Finally, cumulative median recall was calculated for MEDLINE, EMBASE and CENTRAL combined followed by the databases yielding additional studies. Deemed eligible was twenty-three systematic reviews and the databases included other than MEDLINE, EMBASE and CENTRAL was AMED, CINAHL, HealthSTAR, MANTIS, OT-Seeker, PEDro, PsychINFO, SCOPUS, SportDISCUS and Web of Science. Cumulative median recall for combined searching in MEDLINE, EMBASE and CENTRAL was 88.9% and increased to 90.9% when adding 10 additional databases. Searching MEDLINE, EMBASE and CENTRAL was not sufficient for identifying all effect studies on musculoskeletal disorders, but additional ten databases did only increase the median recall by 2%. It is possible that searching databases is not sufficient to identify all relevant references, and that reviewers must rely upon

    The eggs of the European cuttlefish, Sepia officinalis, develop attached to the seafloor in shallow water habitats and possess a relatively thick black capsule that protects them from the surrounding environment. Since embryological development may take several months, eggs are vulnerable to a variety of threats present in shallow waters, including predation. This study investigates predation of S. officinalis eggs by benthic invertebrates. Twenty-eight invertebrate species from 6 different phyla and with diverse feeding habits were tested as potential predators under laboratory conditions. We also investigated how the feeding traits of these species are related to the mechanical ability to break the egg capsule and prey upon cuttlefish embryos. Species that fed on cuttlefish eggs were the sea snail Bolinus brandaris, the crab Cancer pagurus, the hermit crab Dardanus arrosor, the lobster Homarus gammarus, the invasive blue crab Callinectes sapidus, the shrimp Squilla mantis, the sea urchins Echinus melo, Cidaris sp. and Paracentrotus lividus and the starfish Astropecten aranciacus. It is of note that C. sapidus is a potential predatory crab, which raises the concern that this invasive species may constitute a novel threat for cuttlefish eggs as more populations become established in NE Atlantic waters. Of the biological traits examined, prey capture tools in the tested species best explained the experimental feeding results, suggesting that predation of S. officinalis eggs was determined generally by a mechanical factor and highlighting the importance of the protective egg capsule against predators. However, chemosensory factors are likely to be implicated as well. Thus, this work contributes to the understanding of the ecology of early life stages of cuttlefish and the factors that can affect offspring survival and subsequently impact the recruitment of this species.

    Background Spinal pain is a common and often disabling problem. The research on various treatments for spinal pain has, for the most part, suggested that while several interventions have demonstrated mild to moderate short-term benefit, no single treatment has a major impact on either pain or disability. There is great need for more accurate diagnosis in patients with spinal pain. In a previous paper, the theoretical model of a diagnosis-based clinical decision rule was presented. The approach is designed to provide the clinician with a strategy for arriving at a specific working diagnosis from which treatment decisions can be made. It is based on three questions of diagnosis. In the current paper, the literature on the reliability and validity of the assessment procedures that are included in the diagnosis-based clinical decision rule is presented. Methods The databases of Medline, Cinahl, Embase and MANTIS were searched for studies that evaluated the reliability and validity of clinic-based diagnostic procedures for patients with spinal pain that have relevance for questions 2 (which investigates characteristics of the pain source) and 3 (which investigates perpetuating factors of the pain experience). In addition, the reference list of identified papers and authors' libraries were searched. Results A total of 1769 articles were retrieved, of which 138 were deemed relevant. Fifty-one studies related to reliability and 76 related to validity. One study evaluated both reliability and validity. Conclusion Regarding some aspects of the DBCDR, there are a number of studies that allow the clinician to have a reasonable degree of confidence in his or her findings. This is particularly true for centralization signs, neurodynamic signs and psychological perpetuating factors. There are other aspects of the DBCDR in which a lesser degree of confidence is warranted, and in which further research is needed. PMID:18694490

    Infrared spectroscopy is a powerful technique for the exploration of planetary surfaces with remote sensing observations [e.g., 1]. The MERTIS (Mercury Radiometer and Thermal Infrared Spectrometer) instrument onboard the BepiColombo spacecraft is designed to explore the surface mineralogy of Mercury in the wavelength region from 7 μ m to 14 μ m [2]. Mercury's surface reaches dayside temperatures of about 700 K [3]. It is well known that bondings between atoms change with temperature, resulting in infrared spectra changes with temperature [4]. In particular, rock-forming minerals like silicates show distinct absorption bands in the infrared due to molecular vibrations, for example, of Si-O bondings [4]. To accurately understand and correctly interpret returned MERTIS data, it is necessary to collect laboratory data of analogue materials under condition similar to Mercury [5]. It is known from previous investigations [5] that the Reststrahlenbands of olivine shift with temperature. In this work we report on temperature effects on Mercury analogue materials in ambient air. At the IRIS (Infrared & Raman for Interplanetary Spectroscopy) laboratory in Münster we used a Bruker VERTEX 70v IR spectrometer together with a Harrick heating stage in a Praying Mantis Diffuse Reflectance Accessory to measure mid-infrared reflectance of mineral powder samples with different grain sizes at increasing temperatures. We report on our spectral results for a natural olivine with Fo91 with a grain size range between 63 μ m and 125 μ m as well as a natural labradorite with a grain size range between 90 μ m and 125 μ m. Spectra were collected at 26, 75, 150, 200, 250, 300, and 350 degrees Celsius with a liquid nitrogen cooled MCT detector under normal ambient pressure. To ensure complete thermal equilibrium of our measured samples, we heated them to higher temperatures and subsequently cooled them to the temperatures at which the spectra were taken. For background calibration, we

    To compare the outcomes among war veterans who pray/do not pray and who were not suffering mental disorders after the Bosnia-Herzegovina war (1992-95). The sample consists of 100 healthy Bosnian war veterans divided in two equal groups-one, a highly religious group inside which were individuals who perform five obligatory prayers every day, and another group of individuals who do not practice any daily prayer. We used Minnesota Multiphase Personal Inventory (MMPI), Profile Index of Emotions (PIE) and Life Style Questionnaire (LSQ). War veterans who prayed had significantly higher levels for: incorporation, self-protection, and for reactive formation; but significantly lower levels for regression, compensation, transfer, no-controlling, oppositional and aggressiveness than their peers who did not pray. Practicing religion (regular performing daily prayers) is associated with reduction of tendencies towards the tendency for risk, impulsiveness, and aggression. It is also associated with successful overcoming of emotional conflicts in war veterans who practiced religion than their peers who did not practice religion.

    This study examined the correlates of religiosity among Jewish Israelis aged 50 and older. Based on the second wave of Survey of Health, Ageing and Retirement in Europe, the findings show that almost half the Jewish respondents never pray and that, on average, prayer frequency is lower among Jewish Israelis than it is among most of their European counterparts. Multivariate logistic analyses revealed that those who pray more often have more health conditions, are less able to make ends meet financially and have fewer years of education. However, when facing ill health those who pray more often display a relatively lesser decline in their sense of well being.

    To analyze national trends in the use of prayer among individuals with depression, we adopted a cross-sectional design with data from the adult Alternative Medicine supplement of the National Health Interview Survey 2002 and 2007. Prayer use and depression were combined into 4 categories: (a) prayed in the past 12 months and depressed; (b) prayed in the past 12 months and not depressed; (c) never prayed but depressed; and (d) never prayed and not depressed. Chi-square tests and multinomial logistic regressions were performed to analyze group differences. All analyses were adjusted for the complex sample design and conducted in SAS-callable SUDAAN. Use of prayer for depression was steady at 6.9 % across time; however, general prayer increased significantly between 2002 and 2007 (40.2 vs. 45.7). Women, aged 50-64, unmarried, with high school education were more likely to use prayer while depressed compared to those who were neither depressed nor prayed. Lifestyle behaviors (e.g. alcohol, smoking, exercise) were also associated with prayer use and depression. Prayer use for depression remained steady with unique relationships occurring among those who smoke, use alcohol, and have irregular exercise. Individuals' use of prayer as a potential complementary treatment for depression suggests that it is critical for mental and physical health treatment providers to be aware of the use of prayer as a coping resource.

    Objective To analyze national trends in the use of prayer among individuals with depression. Method We adopted a cross-sectional design with data from the adult Alternative Medicine supplement of the National Health Interview Survey (NHIS) 2002 and 2007. Prayer use and depression were combined into 4 categories: prayed in the past 12 months and depressed; 2) prayed in the past 12 months and not depressed; 3) never prayed but depressed; and 4) never prayed and not depressed. Chi-square tests and multinomial logistic regressions were performed to analyze group differences. All analyses adjusted for the complex sample design and were conducted in SAS-callable SUDAAN. Results Use of prayer for depression was steady at 6.9% across time, however general prayer increased significantly between 2002 and 2007 (40.2 vs. 45.7). Women, aged 50-64, not-married, with a high school education were more likely to use prayer while depressed compared to those who were neither depressed nor prayed. Lifestyle behaviors (ex. alcohol, smoking, exercise) were also associated with prayer use and depression. Discussion Prayer use for depression remained steady with unique relationships occurring among those who smoke, use alcohol, and have irregular exercise. Individuals’ use of prayer as a potential complementary treatment for depression suggests that it is critical for mental and physical health treatment providers to be aware of the use of prayer as a coping resource.

    Climate change models for the north­ern Rocky Mountains predict warming and changes in water availability that may alter vegetation. Changes to vegetation may include timing of plant life-history events, or phenology, such as green-up, flower­ing, and senescence. These changes could make forage available earlier in the growing season, but shifts in phenol­ogy may also result in earlier senescence (die-off or dormancy) and reduced overall production. Greenness indices such as the normalized difference vegetation index (NDVI) are regularly used to quantify greenness over large areas using remotely sensed reflectance data. The timing and scale of current satellite data, however, may be insufficient to capture fine-scale differences in phenology that are important indicators of habitat quality. The Wyoming Range Mule Deer herd is one of the largest in the west but it declined precipitously in the early 1990s and has not recovered. Accurate measurement of greenness over space and time would allow managers to better understand the role of plant phenology and productivity in mule deer population dynamics, for example. To connect spatial and temporal patterns of plant productivity with habitat quality, we compare greenness patterns (MODIS data) with migratory mule deer movement (GPS collars). Sagebrush systems provide winter habitat for mule deer. To understand sagebrush phenology as an indicator of productivity, we constructed NDVI time series and compared dates of phenological stages and magnitudes of greenness from three perspectives: at-surface/species-specific (mantis sensors: downward looking, <1m above vegetation); near surface/site-specific (PhenoCam: oblique, 2m); and satellite/landscape-scale (varied platforms). Greenness indices from these sensors contribute unique insights to understanding vegetation phenology, snow cover and reflectance. Understanding phenology and productivity at multiple scales can help guide resource management decisions related to

    In Cadarache development on negative ion sources is being carried out on the KAMABOKO III ion source on the MANTIS test bed. This is a model of the ion source designed for the neutral beam injectors of ITER. This ion source has been developed in collaboration with JAERI, Japan, who also designed and supplied the ion source. Its target performance is to accelerate a D- beam, with a current density of 200 A/m2 and <1 electron extracted per accelerated D- ion, at a source filling pressure of 0.3 Pa. For ITER a continuous ion beam must be assured for pulsemore » lengths of 1000 s, but beams of up to 3,600 s are also envisaged. The ion source is attached to a 3 grid 30 keV accelerator (also supplied by JAERI) and the accelerated negative ion current is determined from the energy deposited on a calorimeter. During long pulse operation ({<=}1000 s) it was found that the current density of both D- and H- beams, measured at the calorimeter was lower than expected and that a large discrepancy existed between the accelerated currents measured electrically and those transmitted to the calorimeter. The possibility that this discrepancy arose because the accelerated current included electrons (which would not be able to reach the calorimeter) was investigated and subsequently eliminated. Further studies have shown that the fraction of the electrical current reaching the calorimeter varies with the pulse length, which led to the suggestion that one or more of the accelerator grids were distorting due to the incident power during operation, leading to a progressive deterioration in the beam quality.. New extraction and acceleration grids have been designed and installed, which should have a better tolerance to thermal loads than those previously used. This paper describes the measurements of the power transmission and distribution using these grids.« less

    Most Americans pray; many pray about their health. When they are hospitalized, however, do patients want an offer of prayer from a healthcare provider? This project allowed for the measurement of hospitalized patient's responses to massage therapists' offers of a colloquial prayer after a massage. After the intervention, 78 patients completed questionnaires that elicited quantitative data that were analyzed using uni- and bivariate statistical analyses. In this sample, 88% accepted the offer of prayer, 85% found it helpful, and 51% wanted prayer daily. Patients may welcome prayer, as long as the clinician shows "genuine kindness and respect."

  15. Signal information available for plume source tracking with and without surface waves and learning by undergraduates assisting with the research

    Autonomous vehicles have had limited success in locating point sources of pollutants, chemicals, and other passive scalars. However, animals such as stomatopods, a mantis shrimp, track odor plumes easily for food, mates, and habitat. Laboratory experiments using Planar Laser Induced Fluorescence measured odor concentration downstream of a diffusive source with and without live stomatopods to investigate their source-tracking strategies in unidirectional and "wave-affected" (surface waves with a mean current) flows. Despite the dearth of signal, extreme temporal variation, and meandering plume centerline, the stomatopods were able to locate the source, especially in the wave-affected flow. Differences in the two plumes far from the source (>160 cm) appeared to help the animals in the wave-affected flow position themselves closer to the source (<70 cm) at times with relatively large amounts of odor and plume filaments of high concentration. At the height of the animals' antennules, the site of their primary chemosensors, the time-averaged Reynolds stresses in the two flows were approximately the same. The temporal variation in stresses over the wave cycle may be responsible for differences in the two plumes. The antennule height falls between a region of large peaks in Reynolds stress in phase with peaks in streamwise acceleration, and a lower region with a smaller Reynolds stress peak in phase with maximum shear during flow reversal. Six undergraduate students assisted with the research. We documented their daily activities and ideas on plume dispersion using open-ended interviews. Most of their time was spent on tasks that required no understanding of fluid mechanics, and there was little evidence of learning by participation in the RAship. One RA's conceptions of turbulence did change, but a group workshop seemed to support this learning more than the RAship. The documented conceptions could aid in curriculum design, since situating new information within current

    Lightweight and high impact performance composite design is a big challenge for scientists and engineers. Inspired from well-known biological materials, e.g., the bones, spider silk, and claws of mantis shrimp, artificial composites have been synthesized for engineering applications. Presently, the design of ballistic resistant composites mainly emphasizes the utilization of light and high-strength fibers, whereas the contribution from matrix materials receives less attention. However, recent ballistic experiments on fiber-reinforced composites challenge our common sense. The use of matrix with "low-grade" properties enhances effectively the impact performance. In this study, we establish a dynamic shear-lag model to explore the energy dissipation through viscous matrix materials in fiber-reinforced composites and the associations of energy dissipation characteristics with the properties and geometries of constituents. The model suggests that an enhancement in energy dissipation before the material integrity is lost can be achieved by tuning the shear modulus and viscosity of a matrix. Furthermore, our model implies that an appropriately designed staggered microstructure, adopted by many natural composites, can repeatedly activate the energy dissipation process and thus improve dramatically the impact performance. This model demonstrates the role of matrix in energy dissipation, and stimulates new advanced material design concepts for ballistic applications. Biological composites found in nature often possess exceptional mechanical properties that man-made materials haven't be able to achieve. For example, it is predicted that a pencil thick spider silk thread can stop a flying Boeing airplane. Here, by proposing a dynamic shear-lag model, we investigate the relationships between the impact performance of a composite with the dimensions and properties of its constituents. Our analysis suggests that the impact performance of fiber-reinforced composites could improve

    The Retrieval Knowledge Center sponsored a meeting in June 2009 to review challenges and gaps to retrieval of tank waste heels. The facilitated meeting was held at the Savannah River Research Campus with personnel broadly representing tank waste retrieval knowledge at Hanford, Savannah River, Idaho, and Oak Ridge. This document captures the results of this meeting. In summary, it was agreed that the challenges to retrieval of tank waste heels fell into two broad categories: (1) mechanical heel waste retrieval methodologies and equipment and (2) understanding and manipulating the heel waste (physical, radiological, and chemical characteristics) to support retrieval optionsmore » and subsequent processing. Recent successes and lessons from deployments of the Sand and Salt Mantis vehicles as well as retrieval of C-Area tanks at Hanford were reviewed. Suggestions to address existing retrieval approaches that utilize a limited set of tools and techniques are included in this report. The meeting found that there had been very little effort to improve or integrate the multiple proven or new techniques and tools available into a menu of available methods for rapid insertion into baselines. It is recommended that focused developmental efforts continue in the two areas underway (low-level mixing evaluation and pumping slurries with large solid materials) and that projects to demonstrate new/improved tools be launched to outfit tank farm operators with the needed tools to complete tank heel retrievals effectively and efficiently. This document describes the results of a meeting held on June 3, 2009 at the Savannah River Site in South Carolina to identify technology gaps and potential technology solutions to retrieving high-level waste (HLW) heels from waste tanks within the complex of sites run by the U. S. Department of Energy (DOE). The meeting brought together personnel with extensive tank waste retrieval knowledge from DOE's four major waste sites - Hanford, Savannah

  18. Computing the sensitivity of drag and lift in flow past a circular cylinder: Time-stepping versus self-consistent analysis

    Meliga, Philippe

    2017-07-01

    We provide in-depth scrutiny of two methods making use of adjoint-based gradients to compute the sensitivity of drag in the two-dimensional, periodic flow past a circular cylinder (Re≲189 ): first, the time-stepping analysis used in Meliga et al. [Phys. Fluids 26, 104101 (2014), 10.1063/1.4896941] that relies on classical Navier-Stokes modeling and determines the sensitivity to any generic control force from time-dependent adjoint equations marched backwards in time; and, second, a self-consistent approach building on the model of Mantič-Lugo et al. [Phys. Rev. Lett. 113, 084501 (2014), 10.1103/PhysRevLett.113.084501] to compute semilinear approximations of the sensitivity to the mean and fluctuating components of the force. Both approaches are applied to open-loop control by a small secondary cylinder and allow identifying the sensitive regions without knowledge of the controlled states. The theoretical predictions obtained by time-stepping analysis reproduce well the results obtained by direct numerical simulation of the two-cylinder system. So do the predictions obtained by self-consistent analysis, which corroborates the relevance of the approach as a guideline for efficient and systematic control design in the attempt to reduce drag, even though the Reynolds number is not close to the instability threshold and the oscillation amplitude is not small. This is because, unlike simpler approaches relying on linear stability analysis to predict the main features of the flow unsteadiness, the semilinear framework encompasses rigorously the effect of the control on the mean flow, as well as on the finite-amplitude fluctuation that feeds back nonlinearly onto the mean flow via the formation of Reynolds stresses. Such results are especially promising as the self-consistent approach determines the sensitivity from time-independent equations that can be solved iteratively, which makes it generally less computationally demanding. We ultimately discuss the extent to

    Communication with children and adolescents with cancer about their disease and treatment and the implications of these is an important aspect of good quality care. It is often poorly performed in practice. Various interventions have been developed that aim to enhance communication involving children or adolescents with cancer. To examine the effects of interventions to enhance communication with children and/or adolescents about their cancer, its treatment and their implications. The following electronic databases were searched: Cochrane Library; Medline; PsycLit; Cinahl; Cancerlit; EMBASE; Sociofile; Health Management Information Consortium; ASSIA; LISA; ERIC; PAIS; Information Science Abstracts; Dissertation Abstracts; JICST; Pascal; Linguistics and Language Behavior Abstracts; Mental Health Abstracts; AMED; MANTIS. Bibliographies of identified studies were also checked and contact made with experts in the field. Randomised and non-randomised controlled trials and before and after studies that evaluated the effects of interventions to enhance communication with children and/or adolescents about their cancer, treatment and related issues. Data relating to the interventions, populations and outcomes studied and the design and methodological quality of included studies were extracted by one reviewer and checked by another reviewer. A narrative summary of the results is presented. Six studies met the criteria for inclusion. They were diverse in terms of the interventions evaluated, study designs used, types of people who participated and the outcomes measured. One study of a computer-assisted education programme reported improvements in knowledge and understanding about blood counts and cancer symptoms. Two out of two studies of school reintegration programs reported improvements in some aspects of psychosocial wellbeing (one in anxiety and one in depression), social wellbeing (two in social competence and one in social support) and behavioural problems; and one

    Badano, Aldo; Kyprianou, Iacovos S.; Jennings, Robert J.

    We describe the anisotropy in imaging performance caused by oblique x-ray incidence in indirect detectors for breast tomosynthesis based on columnar scintillator screens. We use MANTIS, a freely available combined x-ray, electron, and optical Monte Carlo transport package which models the indirect detection processes in columnar screens, interaction by interaction. The code has been previously validated against published optical distributions. In this article, initial validation results are provided concerning the blur for particular designs of phosphor screens for which some details with respect to the columnar geometry are available from scanning electron microscopy. The polyenergetic x-ray spectrum utilized comes frommore » a database of experimental data for three different anode/filter/kVp combinations: Mo/Mo at 28 kVp, Rh/Rh at 28 kVp, and W/Al at 42 kVp. The x-ray spectra were then filtered with breast tissue (3, 4, and 6 cm thickness), compression paddle, and support base, according to the oblique paths determined by the incidence angle. The composition of the breast tissue was 50%/50% adipose/glandular tissue mass ratio. Results are reported on the pulse-height statistics of the light output and on spatial blur, expressed as the response of the detector to a pencil beam with a certain incidence angle. Results suggest that the response is nonsymmetrical and that the resolution properties of a tomosynthesis system vary significantly with the angle of x-ray incidence. In contrast, it is found that the noise due to the variability in the number of light photons detected per primary x-ray interaction changes only a few percent. The anisotropy in the response is not less in screens with absorptive backings while the noise introduced by variations in the depth-dependent light output and optical transport is larger. The results suggest that anisotropic imaging performance across the detector area can be incorporated into reconstruction algorithms for improving

    Literature review of quality of clinical trials. To determine the methodological quality of published randomized controlled trials that used spinal manipulation and/or mobilization to treat patients with tension-type headache (TTH), cervicogenic headache (CeH), and migraine (M) in the last decade. TTH, CeH, and M are the most prevalent types of headaches seen in adults. Individuals who have headaches frequently use physical therapy, manual therapy, or chiropractic care. Randomized controlled trials are considered an optimal method with which to assess the efficacy of any intervention. Computerized literature searches were performed in MEDLINE, EMBASE, COCHRANE, AMED, MANTIS, CINHAL, and PEDro databases. Randomized controlled trials in which spinal manipulation and/or mobilization had been used for TTH, CeH, and M published in a peer-reviewed journal as full text, and with at least 1 clinically relevant outcome measure (ie, headache intensity, duration, or frequency) were reviewed. The methodological quality of the studies was assessed independently by 2 reviewers using a set of predefined criteria. Only 8 studies met all the inclusion criteria. One clinical trial evaluated spinal manipulation and mobilization together, and the remaining 7 assessed spinal manipulative therapy. No controlled trials analyzing exclusively the effects of spinal mobilization were found. Methodological scores ranged from 35 to 56 points out of a theoretical maximum of 100 points, indicating an overall poor methodology of the studies. Only 2 studies obtained a high-quality score (greater than 50 points). No significant differences in quality scores were found based on the type of headache investigated. Methodological quality was not associated with the year of publication (before 2000, or later) nor with the results (positive, neutral, negative) reported in the studies. The most common flaws were a small sample size, the absence of a placebo control group, lack of blinded patients, and no

    Recent research suggests that epidemiological forces in religion and health can have opposed effects. Using longitudinal data of people aged 50+ included in wave 1 (2004-2005) of the Survey of Health, Ageing and Retirement in Europe (SHARE), and followed up through waves 2 (2006-2007), 4 (2011) and 5 (2013), we examined two forms of religious internalization and their association with health. Multivariate logistic regressions were used to examine all associations. Taking part in a religious organization was associated with lower odds of GALI (global activity limitation index) (OR = 0.86, 95% CI 0.75, 0.98) and depressive symptoms 0.80 (95% CI 0.69, 0.93), whereas being religiously educated lowered odds of poor self-rated health (SRH) 0.81 (95% CI 0.70, 0.93) and long-term health problems 0.84 (95% CI 0.74, 0.95). The more religious had lower odds of limitations with activities of daily living 0.76 (95% CI 0.58, 0.99) and depressive symptoms 0.77 (95% CI 0.64, 0.92) than other respondents, and compared to people who only prayed and did not have organizational involvement, they had lower odds of poor SRH 0.71 (95% CI 0.52, 0.97) and depressive symptoms 0.66 (95% CI 0.50, 0.87). Conversely, people who only prayed had higher odds of depressive symptoms than non-religious people 1.46 (95% CI 1.15, 1.86). Our findings suggest two types of religiousness: 1. Restful religiousness (praying, taking part in a religious organization and being religiously educated), which is associated with good health, and 2. Crisis religiousness (praying without other religious activities), which is associated with poor health.

    Social buffering is characterized by attenuation of stress in the presence of others, with supportive individuals providing superior buffering. We were interested in learning if the implied presence of a supportive entity, God, would reduce acute stress. Participants were randomly assigned to one of three conditions: prayer, encouraging self-talk, and control. They were subsequently placed in a stressful situation. Self ratings of stress were lower among the prayer and self-talk conditions relative to controls. Systolic and diastolic blood pressures only among those who prayed were lower than controls; however, prayer and self-talk did not differ. Prayer alone did not significantly reduce stress, perhaps because the majority of students in the prayer condition did not consider reading a prayer to constitute praying.

    In this study, we explored how adolescents in rural Kenya apply religious coping in sexual decision-making in the context of high rates of poverty and Human Immunodeficiency Virus (HIV). Semi-structured interviews were conducted with 34 adolescents. One-third (13) reported religious coping related to economic stress, HIV, or sexual decision-making; the majority (29) reported religious coping with these or other stressors. Adolescents reported praying for God to partner with them to engage in positive behaviors, praying for strength to resist unwanted behaviors, and passive strategies characterized by waiting for God to provide resources or protection from HIV. Adolescents in Sub-Saharan Africa may benefit from HIV prevention interventions that integrate and build upon their use of religious coping. PMID:22505794

    Iberolacerta populations from the Northern Montes de Leon (NML) were studied by means of external morphology (scalation and biometry), osteology and genetics (mtDNA and microsatellites), searching for their homogeneity ("intrazonalanalysis") and, once verified, comparing them with Iberolacerta monticola s. str. (from Central Cantabrian Mountains)and/. gal ani (from Southern Montes de Leon) ("extrazonal analysis") from neighboring areas.Our "intrazonal analysis" revealed discordances between the different approaches, especially the patterns of variation of nuclear microsatellites (congruent with external morphology) and mtDNA, namely a very low nuclear differentiation between relatively highly differentiated mtDNA lineages. The morphological approach was unable to discriminate any of the populations as significantly different from the others in the NML. Mitochondrial DNA revealed a haplotype lineage closely related to I. galani (MNL-II in our text) in some specimens of Sierra de Villabandfn and Suspiron, but these populations are morphologically indistinguishable from the main part of the other populations that belong to lineage NML-1,phylogenetically closer to/. monticola. After a separation from I. manti cola ca. 1.8 Mya, the populations in this geographic region must have suffered at least two different waves of gene flow from I. gal ani, the second one not much later than 0.5 Mya. Microsatellite results indicate that all the NML populations are genetically similar in terms of their nuclear genomes,independently of their mitochondrial differentiation (NML-I vs. NML-II haplotype groups). Since all the morphological and microsatellite evidences point towards the fact that, independently of the mitochondrial haplotypes that they bear (NML-1 or NML-II), there is only one taxon in the area, we describe it as: Iberolacerta monticola astur ssp. nov.Concerning the relationships of I. m. astur ssp. nov. with I. monticola s. str. and I. gal ani ("extra zonal analysis"), in

    Midlife habits may be important for the later development of Alzheimer's disease (AD). We estimated the contribution of midlife prayer to the development of cognitive decline. In a door-to-door survey, residents aged ≥65 years were systematically evaluated in Arabic including medical history, neurological, cognitive examination, and a midlife leisure-activities questionnaire. Praying was assessed by the number of monthly praying hours at midlife. Stepwise logistic regression models were used to evaluate the effect of prayer on the odds of mild cognitive impairment (MCI) and AD versus cognitively normal individuals. Of 935 individuals that were approached, 778 [normal controls (n=448), AD (n=92) and MCI (n=238)] were evaluated. A higher proportion of cognitively normal individuals engaged in prayer at midlife [(87%) versus MCI (71%) or AD (69%) (p<0.0001)]. Since 94% of males engaged in prayer, the effect on cognitive decline could not be assessed in men. Among women, stepwise logistic regression adjusted for age and education, showed that prayer was significantly associated with reduced risk of MCI (p=0.027, OR=0.55, 95% CI 0.33-0.94), but not AD. Among individuals endorsing prayer activity, the amount of prayer was not associated with MCI or AD in either gender. Praying at midlife is associated with lower risk of mild cognitive impairment in women. PMID:23116476

    Using data from the 2010 Baylor Religion Survey (N = 1714), this study investigates the prevalence and religious predictors of healing prayer use among US adults. Indicators include prayed for self (lifetime prevalence = 78.8 %), prayed for others (87.4 %), asked for prayer (54.1 %), laying-on-of-hands (26.1 %), and participated in a prayer group (53.0 %). Each was regressed onto eight religious measures, and then again controlling for sociodemographic variables and health. While all religious measures had net effects on at least one healing prayer indicator, the one consistent predictor was a four-item scale assessing a loving relationship with God. Higher scores were associated with more frequent healing prayer use according to every measure, after controlling for all other religious variables and covariates.

    Chiropractors commonly use a combination of interventions to treat people with low-back pain (LBP). To determine the effects of combined chiropractic interventions (that is, a combination of therapies, other than spinal manipulation alone) on pain, disability, back-related function, overall improvement, and patient satisfaction in adults with LBP, aged 18 and older. We searched: The Cochrane Back Review Group Trials Register (May 2009), CENTRAL (The Cochrane Library 2009, Issue 2), and MEDLINE (from January 1966), EMBASE (from January 1980), CINAHL (from January 1982), MANTIS (from Inception) and the Index to Chiropractic Literature (from Inception) to May 2009. We also screened references of identified articles and contacted chiropractic researchers. All randomised trials comparing the use of combined chiropractic interventions (rather than spinal manipulation alone) with no treatment or other therapies. At least two review authors selected studies, assessed the risk of bias, and extracted the data using standardised forms. Both descriptive synthesis and meta-analyses were performed. We included 12 studies involving 2887 participants with LBP. Three studies had low risk of bias. Included studies evaluated a range of chiropractic procedures in a variety of sub-populations of people with LBP.No trials were located of combined chiropractic interventions compared to no treatment. For acute and subacute LBP, chiropractic interventions improved short- and medium-term pain (SMD -0.25 (95% CI -0.46 to -0.04) and MD -0.89 (95%CI -1.60 to -0.18)) compared to other treatments, but there was no significant difference in long-term pain (MD -0.46 (95% CI -1.18 to 0.26)). Short-term improvement in disability was greater in the chiropractic group compared to other therapies (SMD -0.36 (95% CI -0.70 to -0.02)). However, the effect was small and all studies contributing to these results had high risk of bias. There was no difference in medium- and long-term disability. No

  10. THE JOURNAL OF THE CHIROPRACTIC & OSTEOPATHIC COLLEGE OF AUSTRALASIA

    Walker, Bruce F.

    1998-01-01

    The first edition of the Journal of the Chiropractic and Osteopathic College of Australasia was known as COMSIG Review and was published in November, 1992 to coincide with a large conference that COCA had organised in Melbourne. In the first few years the majority of articles were magazine style reviews, similar to these found in the Australian Family Physician. The first Editor was Bruce Walker and subsequent Editors have included John Drinkwater, Stephanie Campbell and John Reggars. The current Editors in Chief, Peter Tuchin and Henry Pollard, are staff members at Macquarie University, Centre of Chiropractic, with a strong background in science and research and both are currently undertaking post-graduate research degrees. Over several years the magazine review style was changed in keeping with a more full journal format. An Editorial Board was formed, comprised of chiropractors, osteopaths and medical practitioners, some of whom are world renowned in their particular field of research. By March, 1996 it was decided to change the name of the journal to Australasian Chiropractic and Osteopathy (ACO). This was a purposeful move to reflect the maturing of the journal and also the growth of the College and in the five years since November 1992, seventy-nine scientific articles have been published. It is anticipated that the journal will continue to be widely distributed throughout the world, with current subscriptions from all Australian undergraduate chiropractic and osteopathic institutions and the vast majority of international undergraduate institutions. ACO is currently indexed with Mantis (formerly Chirolars). The Editorial Panel continue to strive for Australasian Chiropractic and Osteopathy inclusion into Index Medicus and thereby Medline. However, it is recognised that readership of chiropractic journals is very low throughout the world and it is unlikely in the near future that any chiropractic journal other than the Journal of Manipulative and

    Neck pain is one of the three most frequently reported complaints of the musculoskeletal system. Treatments for neck pain are varied, as are the perceptions of benefits. Acupuncture has been used as an alternative to more traditional treatments for musculoskeletal pain. This review summarizes the most current scientific evidence on the effectiveness of acupuncture for acute, subacute and chronic neck pain. To determine the effects of acupuncture for individuals with neck pain. We searched CENTRAL (2006, issue 1) and MEDLINE, EMBASE, MANTIS, CINAHL from their beginning to February 2006. We searched reference lists and the acupuncture database TCMLARS in China. Any published trial using randomized (RCT) or quasi-randomized (quasi-RCT) assignment to the intervention groups, either in full text or abstract form, were included. Two reviewers made independent decisions for each step of the review: article inclusion, data abstraction and assessment of trial methodological quality. Study quality was assessed using the Jadad criteria. Consensus was used to resolve disagreements. When clinical heterogeneity was absent, we combined studies using random-effects meta-analysis models. We did not find any trials that examined the effects of acupuncture for acute or subacute pain, but we found 10 trials that examined acupuncture treatments for chronic neck pain. Overall, methodological quality had a mean of 2.3/5 on the Jadad Scale. For chronic mechanical neck disorders, there was moderate evidence that acupuncture was more effective for pain relief than some types of sham controls, measured immediately post-treatment. There was moderate evidence that acupuncture was more effective than inactive, sham treatments measured immediately post-treatment and at short-term follow-up (pooled standardized mean difference (SMD) -0.37, 95% confidence interval (CI) -0.61 to -0.12). There was limited evidence that acupuncture was more effective than massage at short-term follow-up. For chronic

    Neck pain is common, disabling and costly. The effectiveness of electrotherapy as a physiotherapeutic option remains unclear. This update replaces our 2005 Cochrane review on this topic. To assess whether electrotherapy improves pain, disability, patient satisfaction, and global perceived effect in adults with neck pain. Computer-assisted searches of: CENTRAL, MEDLINE, EMBASE, MANTIS, CINAHL, and ICL, without language restrictions, from their beginning to December 2008; handsearched relevant conference proceedings; consulted content experts. Randomised controlled trials in any language, investigating the effects of electrotherapy, used primarily as unimodal treatment for neck pain. Quasi-RCTs and controlled clinical trials were excluded. At least two authors independently conducted citation identification, study selection, data abstraction, and risk of bias assessment. We were unable to statistically pool any of the results, but assessed the quality of the evidence using an adapted GRADE approach. Eighteen small trials (1043 people with neck pain) with 23 comparisons were included. Analysis was limited by trials of varied quality, heterogeneous treatment subtypes and conflicting results. The main findings for reduction of neck pain by treatment with electrotherapeutic modalities are:Very low quality evidence that pulsed electromagnetic field therapy (PEMF), repetitive magnetic stimulation (rMS) and transcutaneous electrical nerve stimulation (TENS) are more effective than placebo.Low quality evidence that permanent magnets (necklace) are not more effective than placebo.Very low quality evidence that modulated galvanic current, iontophoresis and electric muscle stimulation (EMS) are not more effective than placebo.There were only four trials that reported on other outcomes such as function and global perceived effects, but none were of clinical importance. We cannot make any definite statements on the efficacy and clinical usefulness of electrotherapy modalities for

    2010-01-01

    Using data from a 2001–2002 sample of adults aged 65 and older living in the Washington, DC metropolitan area, we examine the associations among religious involvement (as measured by the frequency of attendance at religious services and praying), the belief in divine control, and the sense of mattering—a key component of the self-concept. We also assess the extent to which these patterns vary by gender, race, and education. Findings indicate indirect effects of religious attendance on mattering through divine control beliefs and the frequency of social contact. Praying increases mattering indirectly only through divine control beliefs. Moreover, divine control beliefs are more strongly associated with mattering among women, African Americans, and individuals with less education. We discuss the contribution of these findings for theory about the links between religious involvement, beliefs about God, and psychosocial resources, and the influence of core dimensions of social status and stratification.

    This study is set out to examine the subjective experience of using the Ignatian method of meditation to reflect on and pray through Ruth 2. A group of male and female Theology students from the University of KwaZulu-Natal were invited to reflect upon/pray through Ruth 2 using Ignatian meditation. Following this exercise, participants were invited to participate in a focus group in which they shared their experience of this exercise, focusing particularly on some of the gendered aspects of the experience. The transcribed focus group material was subjected to a critical thematic analysis, in order to identify which core aspects of the experience of using this method of meditation and reflection were responsible for the reported subjective experiences. The analysis also included a comparison of the experience for men and women participating in this exercise, and the differential effect of various aspects of the exercise on men and women.

    The birth of an extremely premature baby is a tragedy, and it is only natural that the parents will rely on the spiritual and religious beliefs that guide the rest of their lives. At this difficult time, parents with strong religious beliefs will hope for divine intervention and pray for a miracle. This paper outlines the difficulties experienced by neonatal nurses when caring for an extremely premature baby whose parents hold on to hope and their belief in divine intervention and a miracle. Data were collected via a questionnaire to Australian neonatal nurses and semi-structured interviews with 24 neonatal nurses in NSW, Australia. A qualitative approach was used to analyse the data. The theme of "hoping for a miracle" was captured by two sub-themes "praying for a miracle" and "oscillating between hope and despair". For some families, the hope of divine intervention seemed all consuming, and the nurses were witness to the desperation and disappointment of families when a miracle was not forthcoming.

    To explore the risk factors on cases regarding work-related acute pesticide poisoning among farmers of Jiangsu province. A population-based, 1:2 matched case-control study was carried out, with 121 patients as case-group paired by 242 persons with same gender, district and age less then difference of 3 years, as controls. Cases were the ones who had suffered from work-related acute pesticide poisoning. A unified questionnaire was used. Data base was established by EpiData 3.1, and SPSS 16.0 was used for both data single factor and multi-conditional logistics regression analysis. Results from the single factor logistic regression analysis showed that the related risk factors were: lack of safety guidance, lack of readable labels before praying pesticides, no regression during application, using hand to wipe sweat, using leaking knapsack, body contaminated during application and continuing to work when feeling ill after the contact of pesticides. Results from multi-conditional logistic regression analysis indicated that the lack of safety guidance (OR=2.25, 95%CI: 1.35-3.74), no readable labels before praying pesticides (OR=1.95, 95%CI: 1.19-3.18), wiping the sweat by hand during application (OR=1.97, 95%CI: 1.20-3.24) and using leaking knapsack during application (OR=1.82, 95%CI:1.10-3.01) were risk factors for the occurrence of work-related acute pesticide poisoning. The lack of safety guidance, no readable labels before praying pesticides, wiping the sweat by hand or using leaking knapsack during application were correlated to the occurrence of work-related acute pesticide poisoning.

    capita costs probably would be much larger. The landslide near the rural community of Manti, Utah, caused an expenditure of about $1,800,000 or about $1,000 per person during the period 1974-76. Because a recurrence for such a landslide cannot be established, it is not possible to develop a meaningful estimate of annual per capita damages. Communities are urged to examine their costs of landslide damage and to evaluate the feasibility of several alternative programs that, for a modest investment, could significantly reduce these losses.

    2016-08-01

    This study investigates the difference of mean gamma EEG power between actual and mimic Salat practices in twenty healthy Muslim subjects. In the actual Salat practice, the participants were asked to recite and performing the physical steps in all four stages of Salat; whereas in the mimic Salat practice, they were instructed to perform only the physical steps without recitation. The gamma power during actual Salat was statistically higher than during mimic Salat in the frontal and parietal regions in all stages. In the actual Salat practice, the left hemisphere exhibited significantly higher mean gamma power in all cerebral regions and all stages, except the central-parietal region in the sitting position, and the frontal area in the bowing position. Increased gamma power during Salat, possibly related to an increase in cognitive and attentional processing, supports the concept of Salat as a focus attention meditation.

  20. Praying until Death: Apostolicism, Delays and Maternal Mortality in Zimbabwe

    PubMed Central

    2016-01-01

    Religion affects people’s daily lives by solving social problems, although it creates others. Female sexual and reproductive health are among the issues most affected by religion. Apostolic sect members in Zimbabwe have been associated with higher maternal mortality. We explored apostolic beliefs and practices on maternal health using 15 key informant interviews in 5 purposively selected districts of Zimbabwe. Results show that apostolicism promotes high fertility, early marriage, non-use of contraceptives and low or non-use of hospital care. It causes delays in recognizing danger signs, deciding to seek care, reaching and receiving appropriate health care. The existence of a customized spiritual maternal health system demonstrates a huge desire for positive maternal health outcomes among apostolics. We conclude that apostolic beliefs and practices exacerbate delays between onset of maternal complications and receiving help, thus increasing maternal risk. We recommend complementary and adaptive approaches that address the maternal health needs of apostolics in a religiously sensitive manner. PMID:27509018

    2002-07-01

    Prayer marks (PMs) are asymptomatic, chronic skin changes that consist mainly of thickening, lichenification, and hyperpigmentation, and develop over a long period of time as a consequence of repeated, extended pressure on bony prominences during prayer. Three hundred and forty-nine Muslims and 24 non-Muslims were examined for the appearance of PMs at different body sites. The prospective study of 349 Muslims (both males and females) with regular praying habits showed the occurrence of PMs on specific locations, such as the forehead, knees, ankles, and dorsa of the feet, leading to dermatologic changes consisting of lichenification and hyperpigmentation. The incidence of PMs was significantly higher in males than in females. Older subjects (over 50 years of age) demonstrated a significantly higher frequency of lichenification and hyperpigmentation, suggesting that repeated pressure and friction for prolonged periods are the causative factors for the development of PMs. Histologic examination of skin biopsies from the affected sites showed compact orthokeratosis, hypergranulosis, dermal papillary fibrosis, and dermal vascularization. PMs were not associated with any risk of secondary complications, such as erythema, bullous formation, and infections. PMs are commonly occurring dermatologic changes in Muslims who pray for prolonged periods.

    A diagnosis of cancer creates multiple problems for affected families, including major changes in living patterns, roles and relationships. It has not been common practice for families and health practitioners to share information with children or adolescents about a family member's cancer, or to allow them to express their feelings about this. In recent years, however, researchers and practitioners have begun to recognise that children and adolescents might appreciate and benefit by being better informed about, and having more opportunity to communicate their responses to, cancer in the family. To examine the effects of different ways of enhancing communication with children and/or adolescents about a family member's cancer and its treatment. We searched the following sources: Cochrane Central Register of Controlled Trials (CENTRAL), The Cochrane Library, Issue 1 2003; MEDLINE (1966 to January week 2 2003); EMBASE (1985 to 2003 week 6); CINAHL (1982 to February Week 1 2003); ERIC (1966 to 23 January 2003); PsycINFO (1985 to February week 1 2003).

    The aim of this study was to determine the complementary and alternative approaches used by parents of children with epilepsy on epilepsy management. This descriptive study included a total of 304 parents of children with epilepsy aged between 0 and 18years evaluated at the Pediatric Neurology Clinic of Akdeniz University Hospital in Turkey between January and May 2013. Data were collected by using a questionnaire developed by the researchers. It was determined that all the parents use complementary and alternative approaches for their children with epilepsy, and the most common approaches are praying (99.3%); keeping their children away from the effects of smoking (79.8%); feeding their children walnuts (79.6%), butter (59.2%), and bone marrow (58.6%); providing their children with good quality sleep (58.6%); and enabling their children to play games (51%). The approaches commonly applied during seizures include praying (96.2%), comforting their children in their arms and showing affection (55.6%), waiting for seizures to finish at home (45.7%), and laying children on their side (41.1%). Of parents, 98% stated that alternative approaches enable them to control their child's seizures, 100% said that alternative approaches have no adverse effect, and 98.4% stated that they will continue to use these approaches. The children's approaches to cope with epilepsy included looking after pets (72.7%), listening to music (70.1%), watching television (64.5%), playing games (55.3%), praying (51%), and spending time with friends (48.7%). Most of the approaches used by parents and children with epilepsy for the management of illness are determined to consist of complementary approaches that may contribute to management of epilepsy. Knowing the approaches of parents and children with epilepsy that could adversely affect disease management is important for educating parents and children to avoid these potentially harmful interventions.

  7. Personal Prayer in Patients Dealing with Chronic Illness: A Review of the Research Literature

    PubMed Central

    Jors, Karin; Baumann, Klaus

    2015-01-01

    Background. Prayer is commonly used among patients for health purposes. Therefore, this review focused on three main questions: (1) why do people turn to prayer in times of illness?, (2) what are the main topics of their prayers?, and (3) how do they pray? Method. We undertook a systematic review of the literature by searching the databases PubMed, Medline, and PsycINFO. The following inclusion criteria were used: (1) participants in the study were patients dealing with an illness, (2) the study examined the use of private rather than intercessory prayer, and (3) the content and purpose of prayer rather than its effects were investigated. Results. 16 articles were included in the final review. Participants suffered from a variety of chronic diseases, mostly cancer. Five main categories for the reasons and topics of prayer were found: (1) disease-centered prayer, (2) assurance-centered prayer, (3) God-centered prayer, (4) others-centered prayer, and (5) lamentations. Among these, disease-centered prayer was most common. Conclusions. Although most patients with chronic diseases do pray for relief from their physical and mental suffering, the intention of their prayers is not only for healing. Rather, prayer can be a resource that allows patients to positively transform the experience of their illness. PMID:25815041

    Purpose examine parents' concerns about subsequent pregnancies after experiencing an infant or child death (newborn to 18 years). Data Sources 39 semi-structured parent (White, Black, Hispanic) interviews 7 and 13 months post infant/child death conducted in English and/or Spanish, audio-recorded, transcribed and content analyzed. Mothers' mean age was 31.8 years, fathers' was 39 years; 11 parents were White, 16 Black, 12 Hispanic. Conclusions Themes common at 7 and 13 months: wanting more children; fear, anxiety, scared; praying to God/God's will; thinking about/keeping the infant's/child's memory and at 7 months importance of becoming pregnant for family members; and at 13 months happy about a new baby. Parents who lost a child in NICU commented more than those who lost a child in PICU. Black and Hispanic parents commented more on praying to God and subsequent pregnancies being God's will than White parents. Implications for Practice Loss of an infant/child is a significant stressor on parents with documented negative physical and mental health outcomes. Assessing parents' subsequent pregnancy plans, recognizing the legitimacy of their fears about another pregnancy, discussing a plan should they encounter problems and carefully monitoring the health of all parents who lost an infant/child is an essential practitioner role.

    Although interpersonal interactions are thought to affect psychopathology in schizophrenia, there is a paucity of data about how older adults with schizophrenia manage interpersonal conflicts. This paper examines interpersonal conflict strategies and their impact on positive symptom remission in older adults with schizophrenia spectrum disorders. The schizophrenia group consisted of 198 persons aged 55 years and over living in the community who developed schizophrenia before age 45. A community comparison group (n = 113) was recruited using randomly selected block-groups. Straus' Conflict Tactics Scale (CTS) was used to assess the ways that respondents handled interpersonal conflicts. Seven conflict management subscales were created based on a principal component analysis with equamax rotation of items from the CTS. The order of the frequency of the tactics that was used was similar for both the schizophrenia and community groups. Calm and Pray tactics were the most commonly used, and the Violent and Aggressive tactics were rarely utilized. In two separate logistic regression analysis, after controlling for confounding variables, positive symptom remission was found to be associated significantly with both the Calm and Pray subscales. The findings suggest that older persons with schizophrenia approximate normal distribution patterns of conflict management strategies and the most commonly used strategies are associated with positive symptom remission.

    Six species of the order Mantodea (praying mantises) are investigated for the presence and sequence of putative adipokinetic hormones (AKHs). The selected species span a wide evolutionary range of various families and subfamilies of the clade Mantodea. The corpora cardiaca of the different species are dissected, methanolic extracts prepared, peptides separated by liquid chromatography, and AKHs detected and sequenced by ion trap mass spectrometry. All six species investigated contain an octapeptide with the primary structure pGlu-Val-Asn-Phe-Thr-Pro-Asn-Trp amide, which is code-named Emppe-AKH and had been found earlier in three other species of Mantodea. Conspecific bioassays with the species Creoboter sp. (family Hymenopodidae) reveal an adipokinetic but not a hypertrehalosemic function of Emppe-AKH. Comparison with other members of the Dictyoptera (cockroaches, termites) show that Emppe-AKH is only found in certain termites, which have been recently placed into the Blattaria (cockroaches) as sister group to the family Cryptocercidae. Termites and cockroaches both show biodiversity in the sequence of AKHs, and some cockroach species even contain two AKHs. In contrast, all praying mantises-irrespective of their phylogenetic position-synthesize uniformly only one and the same octapeptide Emppe-AKH. © 2017 Wiley Periodicals, Inc.

    Over the past few years, Intelligent Spaces (ISs) have received the attention of many Wireless Sensor Network researchers. Recently, several studies have been devoted to identify their common capacities and to set up ISs over these networks. However, little attention has been paid to integrating Fuzzy Rule-Based Systems into collaborative Wireless Sensor Networks for the purpose of implementing ISs. This work presents a distributed architecture proposal for collaborative Fuzzy Rule-Based Systems embedded in Wireless Sensor Networks, which has been designed to optimize the implementation of ISs. This architecture includes the following: (a) an optimized design for the inference engine; (b) a visual interface; (c) a module to reduce the redundancy and complexity of the knowledge bases; (d) a module to evaluate the accuracy of the new knowledge base; (e) a module to adapt the format of the rules to the structure used by the inference engine; and (f) a communications protocol. As a real-world application of this architecture and the proposed methodologies, we show an application to the problem of modeling two plagues of the olive tree: prays (olive moth, Prays oleae Bern.) and repilo (caused by the fungus Spilocaea oleagina). The results show that the architecture presented in this paper significantly decreases the consumption of resources (memory, CPU and battery) without a substantial decrease in the accuracy of the inferred values.

    Religious/spiritual (R/S) coping has been associated with health outcomes in chronically ill adults; however, little is known about how adolescents use R/S to cope with a chronic illness such as sickle cell disease (SCD). Using a mixed method approach (quantitative surveys and qualitative interviews), we examined R/S coping, spirituality, and health-related quality of life in 48 adolescents with SCD and 42 parents of adolescents with SCD. Adolescents reported high rates of religious attendance and belief in God, prayed often, and had high levels of spirituality (e.g., finding meaning/peace in their lives and deriving comfort from faith). Thirty-five percent of adolescents reported praying once or more a day for symptom management. The most common positive R/S coping strategies used by adolescents were: “Asked forgiveness for my sins” (73% of surveys) and “Sought God’s love and care” (73% of surveys). Most parents used R/S coping strategies to cope with their child’s illness. R/S coping was not significantly associated with HRQOL (p = NS). R/S coping, particularly prayer, was relevant for adolescents with SCD and their parents. Future studies should assess adolescents’ preferences for discussing R/S in the medical setting and whether R/S coping is related to HRQOL in larger samples. PMID:19415008

  2. A multirotor platform for mapping and inspecting sub-vertical rock faces

    Only in recent years UAS technology has become accessible to everyone and, hence, it is rapidly becoming a valuable tool for researchers and scientists (Westoby et al., 2012; Nex and Remondino, 2014). Electric multicopters (i.e., multirotor helicopters) are one of the most exciting developments of the last couple of years. Only the development and implementation of advanced flight controllers made the use of multicopters possible. Generally being an aerodynamically unstable UAS they absolutely require a flight controller for stable flight. Several open-source and commercial flight controller are now available which makes it possible to build custom UAS. The current work presents a custom build hexacopter (i.e., a multicopter with six rotors) which was specifically developed for 3D mapping and inspection of sub-vertical rock faces. The main sensor installed on the platform is a Canon 100D DSLR camera. The camera is attached to a two axis gimbal. The roll angle is automatically controlled to keep the camera level during the flight whereas the user controls the tilt angle. The two forward facing arms of the hexacopter have been raised, i.e., they are located higher than the other four propellers (Mantis arms). This provides a clear field of view when looking forward and even makes it possible to look slightly upward without having the propellers in the field of view. A DJI A2 flight controller is installed on the platform and an additional FPV camera can be switched on if pictures are taken in manual mode. So far the flights are all performed in manual mode. The fact that the platform is generally flying very close to very irregular sub-vertical rock faces makes autonomous flights in GPS mode almost impossible. In addition, GPS reception is often very poor around sub-vertical rock faces. One main issue when flying in manual mode is to keep the hexacopter at a constant distance from the surface. As the rock surface gets higher and higher it becomes more and more

    Neck pain is common, disabling and costly. The effectiveness of electrotherapy as a physiotherapeutic option remains unclear. This is an update of a Cochrane review first published in 2005 and previously updated in 2009. This systematic review assessed the short, intermediate and long-term effects of electrotherapy on pain, function, disability, patient satisfaction, global perceived effect, and quality of life in adults with neck pain with and without radiculopathy or cervicogenic headache. We searched CENTRAL, MEDLINE, EMBASE, MANTIS, CINAHL, and ICL, without language restrictions, from their beginning to August 2012; handsearched relevant conference proceedings; and consulted content experts. Randomized controlled trials (RCTs), in any language, investigating the effects of electrotherapy used primarily as unimodal treatment for neck pain. Quasi-RCTs and controlled clinical trials were excluded. We used standard methodological procedures expected by The Cochrane Collaboration. We were unable to statistically pool any of the results, but we assessed the quality of the evidence using an adapted GRADE approach. Twenty small trials (1239 people with neck pain) containing 38 comparisons were included. Analysis was limited by trials of varied quality, heterogeneous treatment subtypes and conflicting results. The main findings for reduction of neck pain by treatment with electrotherapeutic modalities were as follows.Very low quality evidence determined that pulsed electromagnetic field therapy (PEMF) and repetitive magnetic stimulation (rMS) were more effective than placebo, while transcutaneous electrical nerve stimulation (TENS) showed inconsistent results.Very low quality evidence determined that PEMF, rMS and TENS were more effective than placebo.Low quality evidence (1 trial, 52 participants) determined that permanent magnets (necklace) were no more effective than placebo (standardized mean difference (SMD) 0.27, 95% CI -0.27 to 0.82, random-effects model

    This study examined spiritual coping (beliefs and practices) of depressed African American cancer patients through a comparison with depressed White cancer patients and non-depressed African American cancer patients. Using mixed methods, 74 breast (n=41) and prostate (n=33) cancer survivors including 34 depressed and 23 nondepressed African Americans and 17 depressed Whites were interviewed. The interviews were audiotaped and transcribed. Qualitative data analysis identified themes that were coded. The codes were entered into SPSS software. The Fisher's exact test was performed to examine group differences in self-reported spiritual coping. Significantly more depressed African Americans questioned God when learning of a cancer diagnosis than the non-depressed African Americans (p=.03), but they did not differ from the depressed Whites in this regard (p=.70). Significantly more depressed African Americans reported having faith in God (p=.04), reading the bible (p=.02), and conversing with God (p=.01) than did the depressed Whites. They also reported praying alone (p=.01) more frequently than the depressed Whites who, on the other hand, reported praying with others (non-family members) together for one's own health more frequently (p=.04). Depression is associated with a deepening need for spirituality and it affects religious beliefs and practices more in African American than White cancer patients. Given its important role in the lives of African American cancer patients, spirituality may be utilized as a reasonable, culturally-based approach to better assess and treat depression in these patients.

  7. Orientation of Christian Churches

    McCluskey, Stephen C.

    The orientation of Christian churches reflects the historically documented concepts that one should turn eastward to pray and the architectural and liturgical principle that temples and churches should be constructed facing east (often specified as equinoctial east). Since many churches do not face equinoctial east, various attempts have been made to explain this deviation. Among them are the idea that those churches were incorrectly built or that they were oriented toward sunrise on the date their foundation was laid or on the feast or the saint to whom the church was dedicated.

    In nature, shooting mechanisms are used for a variety of purposes, including prey capture, defense, and reproduction. This review offers insight into the working principles of shooting mechanisms in fungi, plants, and animals in the light of the specific functional demands that these mechanisms fulfill. We systematically searched the literature using Scopus and Web of Knowledge to retrieve articles about solid projectiles that either are produced in the body of the organism or belong to the body and undergo a ballistic phase. The shooting mechanisms were categorized based on the energy management prior to and during shooting. Shooting mechanisms were identified with projectile masses ranging from 1·10-9 mg in spores of the fungal phyla Ascomycota and Zygomycota to approximately 10,300 mg for the ballistic tongue of the toad Bufo alvarius. The energy for shooting is generated through osmosis in fungi, plants, and animals or muscle contraction in animals. Osmosis can be induced by water condensation on the system (in fungi), or water absorption in the system (reaching critical pressures up to 15.4 atmospheres; observed in fungi, plants, and animals), or water evaporation from the system (reaching up to -197 atmospheres; observed in plants and fungi). The generated energy is stored as elastic (potential) energy in cell walls in fungi and plants and in elastic structures in animals, with two exceptions: (1) in the momentum catapult of Basidiomycota the energy is stored in a stalk (hilum) by compression of the spore and droplets and (2) in Sphagnum energy is mainly stored in compressed air. Finally, the stored energy is transformed into kinetic energy of the projectile using a catapult mechanism delivering up to 4,137 J/kg in the osmotic shooting mechanism in cnidarians and 1,269 J/kg in the muscle-powered appendage strike of the mantis shrimp Odontodactylus scyllarus. The launch accelerations range from 6.6g in the frog Rana pipiens to 5,413,000g in cnidarians, the

In addition, 25 experts from these same fields presented data to the panel and a conference audience of 1200. Presentations and discussions were divided into 3 phases over 2 1/2 days: (1) presentations by investigators working in areas relevant to the consensus questions during a 2-day public session; (2) questions and statements from conference attendees during open discussion periods that were part of the public session; and (3) closed deliberations by the panel during the remainder of the second day and morning of the third. The conference was organized and supported by the Office of Alternative Medicine and the Office of Medical Applications of Research, National Institutes of Health, Bethesda, Md. The literature, produced from January 1970 to October 1997, was searched through MEDLINE, Allied and Alternative Medicine, EMBASE, and MANTIS, as well as through a hand search of 9 journals that were not indexed by the National Library of Medicine. An extensive bibliography of 2302 references was provided to the panel and the conference audience. Expert speakers prepared abstracts of their own conference presentations with relevant citations from the literature. Scientific evidence was given precedence over clinical anecdotal experience. The panel, answering predefined questions, developed their conclusions based on the scientific evidence presented in the open forum and scientific literature.

    Introduction There is limited research on rapid repeat pregnancies (RRP) among adolescents, especially using nationally representative samples. We examine distal factors-school, family, peers, and public/private religious ties-and their associations with RRP among adolescent mothers. Methods Guided by social development theory, we conducted multivariate logistic regression analyses, adjusted for sociodemographic characteristics, to examine associations between RRP and attachment to school, family, peers, and religion among 1158 female respondents from the National Longitudinal Study of Adolescent to Adult Health (Add Health) who reported at least one live birth before age 20. Results Attachments to conventional institutions were associated with lower likelihood of RRP. Adolescent mothers who had a stronger relationship with their parents had reduced odds of RRP (adjusted odds ratio [aOR] 0.83, 95 % CI 0.71-0.99). Increased odds of RRP were associated with anticipating fewer negative social consequences of sex (aOR 1.18, 95 % CI 1.02-1.35), never praying (versus praying daily; aOR 1.47, 95 % CI 1.10-1.96), and never participating in church-related youth activities (versus participating once a week; 1.04, 95 % CI 1.01-1.07). Discussion After an adolescent birth, social support from family, peers, and the community can benefit young mothers. Private aspects of religiosity may be especially important. Understanding the processes by which these distal factors are linked to the likelihood of RRP is needed to create multifaceted intervention programs that provide diverse methods of support customized to specific circumstances of adolescent mothers.

    The identification of TIR1 as an auxin receptor combined with advanced biophysical instrumentation has led to the development of real-time activity assays for auxins. Traditionally, molecules have been assessed for auxinic activity using bioassays, and agrochemical compound discovery continues to be based on "spray and pray" technologies. Here, we describe the methodology behind an SPR-based assay that uses TIR1 and related F-box proteins with surface plasmon resonance spectrometry for rapid compound screening. In addition, methods for collecting kinetic binding data and data processing are given so that they may support programs for rational design of novel auxin ligands.

    The role of religion and spirituality in coping with disease and promoting health has been reported from many parts of the World. However, no scientific studies on the use of prayers for health and wellbeing have been reported from Pakistan. A cross-sectional survey, using a self-administered questionnaire, was conducted among 1342 graduate and undergraduate students in the twin cities of Islamabad and Rawalpindi. A huge majority of students had prayed for their own as well as their family members' health in the preceding three months. There is a need to better understand the role in Pakistan of prayers related to health.

    The aim of this preliminary study was to investigate whether religious practice can modify quality of life (QoL) in BC patients during chemotherapy. QoL and religion practice questionnaire (RPQ) scores were evaluated in a sample of BC patients in different moments. Before chemotherapy initiation, women with lower physical and social functional scores displayed higher RPQ scores. On the other hand, low RPQ patients worsened some QoL scores over time. Body image acceptance was positively correlated with religious practice and specifically praying activity. This preliminary study suggests the importance of religion in coping with cancer chemotherapy.

  20. Palliative Care for Latino Patients and Their Families: “Whenever We Prayed, She Wept”

    Latinos account for 15% of the US population, a proportion projected to grow to 30% by the year 2050. Although there is tremendous diversity within this community, commonalities of language, beliefs, attitudes, and behaviors unite Latinos, making them more similar than different. For non-Latino and non-Spanish-speaking clinicians, communication barriers and cultural misunderstandings can impede the care of dying Latino patients and their families. We present the case of a young, pregnant, Spanish-speaking woman from Guatemala diagnosed with a fatal leukemia. As illustrated by this case, Latino immigrants face a number of external challenges to optimal end-of-life care: (1) geographic distance as well as political and economic realities often separate patients from their valued families; (2) undocumented immigrants are frequently uninsured, and fear of deportation may create a barrier to accessing health services; (3) language and literacy barriers; and (4) concerns about discrimination. Other Latino issues that may be more pronounced in end-of-life settings include cultural themes and religious and spiritual influences. We recommend that professional interpreters must be used for discussions about goals of care with Spanish-speaking patients and families, or when negotiating conflict between the patient, family, and the health care team. Concrete suggestions are provided for clinicians in working with interpreters, eliciting culturally-based attitudes and beliefs, and implementing universal strategies for clear health communication.

    Culturally adequate medical care is a goal in Germany, but quantitative data concerning inpatients is lacking. Inpatients of a German tertiary hospital: Turkish migrants (T) and Germans (G) were interviewed in their respective native language. 121 T and 121 G were interviewed. 97.5% of T were Muslims, 82.6% of G were Christians. 88.5% of T judged religion as "important" or "very important" (G: 35.8%). 50.8% of T saw their opportunity to pray in the hospital as "bad" or "very bad" (G: 0.9%). Keeping to Islamic dietary rules in the hospital was "difficult" or "very difficult" for 90% of T. For 79.0% of female T care by a same-sex staff was "important" or "very important" (female G: 36.3%, male T: 40.0%, male G: 7.7%). The presence of a same-sex person during examinations or treatments was "much" or "very much" appreciated by 69.7% of female T, if same-sex care was impossible (female G: 25.4%, male T: 28.9%, male G: 6.1%). A retrospective analysis revealed that 5.8% of all 8988 hospital admissions during the period of study recruitment were Turkish migrants. To meet the needs of Turkish migrants German hospitals should improve the opportunity for Muslims to pray. Additionally, the cooperation with local imams should be sought. Precise descriptions of food ingredients or an adapted menu could help T to deal with Muslim dietary commandments. A culturally sensitive hospital should take into account that female as well as male T prefer to be cared of by same-sex physicians and nurses. Georg Thieme Verlag Stuttgart.

    Behavioural risk factors for chronic diseases involve factors relating to lifestyle habits. This study examined the relationship of religious and spiritual beliefs with the adoption and presence of multiple behavioural risk factors (MBRFs) in European adults. Cross-sectional study. Data were used from 16,557 individuals, aged 50+ years, participating in the Survey of Health, Ageing and Retirement in Europe (2004/05). MBRFs clustering was defined by high body weight, smoking, physical inactivity and risky alcohol consumption, and regression estimations with religiosity and prayer use were assessed based on sampling weights. In total, 79.4% of participants had received religious education, 33.4% had used prayer '≥1 time/day' and 53.3% had clustering of 2+ MBRFs. Lower prevalence of smoking was found in males (20.6% vs. 29.4%, P < 0.05), as well as in females (13.1% vs. 22.6%, P < 0.05), who prayed '≥1 time/day', compared to those who never prayed. Categorical regression analysis revealed that the presence of MBRFs was associated negatively with religious education (standardized beta = -0.048, P < 0.001) and positively with low frequency of prayer use (standardized beta = 0.056, P < 0.001). Having received religious education and prayer use were related to the presence of fewer MBRFs in European adults aged 50+ years. These lifestyle factors should be assessed as potential determinants of MBRFs adoption when examining chronic disease development in multicultural populations.

    The proportion of women who patronized traditional birth attendants (TBAs) or modern health care practitioners (MHCPs) was compared, including reasons for their choices. A comparative design was adopted to study 300 respondents selected through a multistage systematic random sampling technique. The instrument for data collection was a validated 21-item structured questionnaire. We observed that 75 (25%) patronized and 80 (27%) preferred TBAs, and 206 (69%) patronized and 220 (75%) preferred MHCPs, while 19 (6%) patronized both. The view that TBAs prayed before conducting deliveries was supported by a majority 75 (94%) of the respondents who preferred them. Factors associated with preference for TBAs should be addressed.

    Colostomy irrigation (CI) is a bowel management method in individuals with permanent colostomy, as an alternative to pouch use, which may provide continence. CI helps the individuals with an artificial stoma to adjust to the stoma and may increase their quality of life (QOL). An uncontrolled intestinal gas discharge invalidates ablution, and noisy gas discharge and smell prevents congregational prayers, which cause problems to Muslims with stomas. Therefore, CI may be an appropriate solution for this patient group. Using the example of one affected individual we discuss how the praying problem can be resolved with teaching to self-perform CI and emphasize the beneficial effects on QOL.

    The purpose of this study was to determine whether distinct latent profiles of religiousness/spirituality exist for ALWH, and if so, are latent profile memberships associated with health-related quality of life (HRQoL). Latent profile analysis of religiosity identified four profiles/groups. Compared to the other three groups, higher levels of emotional well-being were found among young perinatally infected adolescents who attended religious services, but who did not pray privately, feel God's presence or identify as religious or spiritual. Social HRQoL was significantly higher among the highest overall religious/spiritual group. Understanding adolescent profiles of religiousness/spirituality on HRQoL could inform faith-based interventions. PMID:27071797

  7. The perspective of psychosomatic medicine on the effect of religion on the mind-body relationship in Japan.

    2014-02-01

    Shintoism, Buddhism, and Qi, which advocate the unity of mind and body, have contributed to the Japanese philosophy of life. The practice of psychosomatic medicine emphasizes the connection between mind and body and combines the psychotherapies (directed at the mind) and relaxation techniques (directed at the body), to achieve stress management. Participation in religious activities such as preaching, praying, meditating, and practicing Zen can also elicit relaxation responses. Thus, it is time for traditional religions to play an active role in helping those seeking psychological stability after the Great East Japan Earthquake and the ongoing crisis related to the nuclear accident in Fukushima, Japan, to maintain a healthy mind-body relationship.

    Dysarthria is a common manifestation of Parkinson's disease that increases in frequency and intensity with the progress of the disease (Streifler 1984). Up to 20% of Parkinsonian patients are referred for speech and language therapy (S & LT), its aim being to improve the intelligibility of the patient's speech. To compare the efficacy and effectiveness of novel S & LT techniques versus standard S & LT to treat dysarthria in patients with Parkinson's disease. To compare the efficacy and effectiveness of one S & LT technique versus a second form of S & LT to treat Parkinsonian dysarthria. Relevant trials were identified by electronic searches of MEDLINE, EMBASE, CINAHL, ISI-SCI, AMED, MANTIS, REHABDATA, REHADAT, GEROLIT, Pascal, LILACS, MedCarib, JICST-EPlus, AIM, IMEMR, SIGLE, ISI-ISTP, DISSABS, Conference Papers Index, Aslib Index to Theses, the Cochrane Controlled Trials Register, the CentreWatch Clinical Trials listing service, the metaRegister of Controlled Trials, ClinicalTrials.gov, CRISP, PEDro, NIDRR and NRR; and examination of the reference lists of identified studies and other reviews. Only randomised controlled trials (RCT) were included. Data was abstracted independently by KD and RW and differences settled by discussion. Only two trials were identified with only 71 patients. The method of randomisation was good in only one trial and the concealment of allocation was inadequate in both trials. These methodological problems could potentially lead to bias from a number of sources. The methods used in the two studies varied so much that meta-analysis of the results was not possible. Scott 83 compared prosodic exercises with visual cues with prosodic exercises alone (See Glossary: Table 01). The authors examined prosody and intelligibility as outcome measures immediately after therapy. Ramig 95 compared the Lee Silverman Voice Therapy (LSVT) which emphasises increased vocal effort, with respiratory therapy which aimed to increase respiratory muscle activity

    Background In nature, shooting mechanisms are used for a variety of purposes, including prey capture, defense, and reproduction. This review offers insight into the working principles of shooting mechanisms in fungi, plants, and animals in the light of the specific functional demands that these mechanisms fulfill. Methods We systematically searched the literature using Scopus and Web of Knowledge to retrieve articles about solid projectiles that either are produced in the body of the organism or belong to the body and undergo a ballistic phase. The shooting mechanisms were categorized based on the energy management prior to and during shooting. Results Shooting mechanisms were identified with projectile masses ranging from 1·10−9 mg in spores of the fungal phyla Ascomycota and Zygomycota to approximately 10,300 mg for the ballistic tongue of the toad Bufo alvarius. The energy for shooting is generated through osmosis in fungi, plants, and animals or muscle contraction in animals. Osmosis can be induced by water condensation on the system (in fungi), or water absorption in the system (reaching critical pressures up to 15.4 atmospheres; observed in fungi, plants, and animals), or water evaporation from the system (reaching up to −197 atmospheres; observed in plants and fungi). The generated energy is stored as elastic (potential) energy in cell walls in fungi and plants and in elastic structures in animals, with two exceptions: (1) in the momentum catapult of Basidiomycota the energy is stored in a stalk (hilum) by compression of the spore and droplets and (2) in Sphagnum energy is mainly stored in compressed air. Finally, the stored energy is transformed into kinetic energy of the projectile using a catapult mechanism delivering up to 4,137 J/kg in the osmotic shooting mechanism in cnidarians and 1,269 J/kg in the muscle-powered appendage strike of the mantis shrimp Odontodactylus scyllarus. The launch accelerations range from 6.6g in the frog Rana pipiens to 5

    Communication with children and adolescents with cancer about their disease and treatment and the implications of these is an important aspect of good quality care. It is often poorly performed in practice. Various interventions have been developed that aim to enhance communication involving children or adolescents with cancer. To assess the effects of interventions for improving communication with children and/or adolescents about their cancer, its treatment and their implications, updating the 2003 version of this review. In April 2006 we updated searches of the following sources: CENTRAL (The Cochrane Library, issue 1 2006); MEDLINE (Ovid), (2003 to March week 5 2006); EMBASE (Ovid) (2003 to 2006 week 13); PsycINFO (Ovid) (2003 to March week 5 2006); CINAHL (Ovid) (2003 to March week 5 2006); ERIC (CSA) (earliest to 2006); Sociological Abstracts (CSA) (earliest to 2006); Dissertation Abstracts: (2002 to 6 April 2006).In 2003 we conducted searches of CENTRAL; MEDLINE, EMBASE, PsycINFO, CINAHL, ERIC, Sociological Abstracts and Dissertation Abstracts.For the initial (2001) publication of this review we also searched the following databases: PsycLIT; Cancerlit; Sociofile; Health Management Information Consortium; ASSIA; LISA; PAIS; Information Science Abstracts; JICST; Pascal; Linguistics and Language Behavior Abstracts; Mental Health Abstracts; AMED; MANTIS.We also searched the bibliographies of studies assessed for inclusion, and contacted experts in the field. Randomised and non-randomised controlled trials, and before and after studies, evaluating the effects of interventions for improving communication with children and/or adolescents about their cancer, treatment and related issues. Data relating to the interventions, populations and outcomes studied and the design and methodological quality of included studies were extracted by one review author and checked by another review author.

    Although numerous studies suggest that religious involvement is associated with a wide range of favorable health outcomes, it is unclear whether this general pattern extends to cellular aging. In this paper, we tested whether leukocyte telomere length varies according to several dimensions of religious involvement. We used cross-sectional data from the Nashville Stress and Health Study (2011-2014), a large probability sample of 1252 black and white adults aged 22 to 69 living in Davidson County, TN, USA. Leukocyte telomere length was measured using the monochrome multiplex quantitative polymerase chain reaction method with albumin as the single-copy reference sequence. Dimensions of religious involvement included religiosity, religious support, and religious coping. Our multivariate analyses showed that religiosity (an index of religious attendance, prayer frequency, and religious identity) was positively associated with leukocyte telomere length, even with adjustments for religious support, religious coping, age, gender, race, education, employment status, income, financial strain, stressful life events, marital status, family support, friend support, depressive symptoms, smoking, heavy drinking, and allostatic load. Unlike religiosity, religious support and religious coping were unrelated to leukocyte telomere length across models. Depressive symptoms, smoking, heavy drinking, and allostatic load failed to explain any of the association between religiosity and telomere length. To our knowledge, this is the first population-based study to link religious involvement and cellular aging. Although our data suggest that adults who frequently attend religious services, pray with regularity, and consider themselves to be religious tend to exhibit longer telomeres than those who attend and pray less frequently and do not consider themselves to be religious, additional research is needed to establish the mechanisms underlying this association.

    To critically analyze appropriate clinical studies to assess the relationship between health conditions and the frequency of private prayer. Private prayer is defined as individuals praying for themselves. Using PubMed and other search engines, we identified over 300 articles reporting relationships between prayer and health conditions. We identified 41 observational clinical studies that evaluated the relationship between private prayer and health conditions. Prayer scores of 5 to 1 were assigned to studies, with 5 being private prayer for health and 1 being prayer in combination with meditation or Bible study. Frequency scores ranged from 3 to 1 with 3 being twice daily or more and 0 when frequency was not assessed. Studies were ranked from 8 to 1 based on the sum of Prayer and Frequency Scores. Twenty-one studies had Prayer-Frequency scores of 5 to 8, indicating that they evaluated private prayer (praying for one's own health) of suitable frequency in association with health conditions. Nine of 11 studies indicated that private prayer was associated with a significantly lower prevalence of depression (P value, <0.01). Optimism as well as coping were significantly improved by prayer in four studies (P value, P < 0.01). In 10 studies of mental health conditions-including anxiety and confusion-there was a significant benefit associated with prayer (P < 0.01), In the reviewed studies, prayer did not have a significant effect on physical health or blood pressure. The reported observational studies suggest that frequent private prayer is associated with a significant benefit for depression, optimism, coping, and other mental health conditions such as anxiety. Controlled clinical trials are required to critically assess the associations of private prayer and health conditions.

    Complementary and alternative medicine (CAM) for treatment of cancer and for supportive care of cancer patients must be clearly separated. There is encouraging evidence for CAM in the latter area, such as acupuncture and progressive muscle relaxation for chemotherapy-related nausea and vomiting, and aromatherapy for decreasing anxiety and increasing quality of life. However, there are limited data about CAM used by gynecologic cancer patients, especially in Thai women. Therefore, the authors aimed to investigate the proportion and types of CAM using in our gynecologic cancer patients. This cross-sectional survey was conducted between October to December, 2008. Totals of 50 admitted and 50 walk-in gynecologic cancer patients 1 month after diagnosis, aged more than 20 years and able to give informed consent, were selected for one-by-one interview by random walking survey. Among the 100 interviewed patients, aged 21-69 (mean=50.12), there were 46 cases of cervical cancers, 35 of ovarian cancers, 18 of endometrial cancers (two of these also had ovarian cancers), 2 of malignant gestational trophoblastic diseases, 1 of vulvar cancer, and 1 liver cancer (in a patient with ovarian cancer). Some 67% (95% CI, 57.8-76.2%) of them used CAM. As diet modifications, 11 used Chinese vegetarian, 8 common vegetarian, 5 Cheewajit, and 1 macrobiotics. Five of them used dietary supplements while colonic detoxification was emplyed in three. As herbal medicines, 27 used Thai herbs, 4 Chinese herbs, and 1 a herbal sauna. Twelve were receiving Thai massage. As exercises, 23 used aerobics and 5 stretching. Interestingly, 62 of them used Buddhist praying while only 3 employed native magic. The three most common forms of CAM used by our gynecologic cancer patients were Buddhist praying (62/67, 92.5%), followed by herbal medicines (27/67, 40.3%) and exercises (25/67, 37.3%).

    The purpose of this study was to determine whether distinct latent profiles of religiousness/spirituality exist for ALWH, and if so, are latent profile memberships associated with health-related quality of life (HRQoL). Latent profile analysis of religiosity identified four profiles/groups. Compared to the other three groups, higher levels of emotional well-being were found among young perinatally infected adolescents who attended religious services, but who did not pray privately, feel God's presence or identify as religious or spiritual. Social HRQoL was significantly higher among the highest overall religious/spiritual group. Understanding adolescent profiles of religiousness/spirituality on HRQoL could inform faith-based interventions. Trial registration NCT01289444.

    Male reproductive success is obviously mate limited, which implies that males should rarely be choosy. One extreme case of a reproductive (or mating) cost is sexual cannibalism. Recent research has proposed that male mantids (Parastagmatoptera tessellata) are choosy and not complicit in cannibalism and that they modify behavior towards females based on the risk imposed by them. Since female cannibalism depends on females' energetic state (i.e. hunger) we investigated whether male mantids are capable of using environmental cues that provide information regarding the energetic state of females to make their mate choices. Under laboratory conditions, males were confronted individually with three options: a female eating a prey, a female without a prey, and a male eating a prey (as a control for the presence of prey). Each subject comprising a choice was harnessed and placed in the corners of a triangular experimental arena at an equidistant distance from the focal male. The prey was a middle size cricket that subjects ate in approximately twenty minutes. The behavior of focal males was recorded for six hours. Females were under the same deprivation regime and, in line with previous studies, consuming one cricket did not significantly increase females' abdomen girth. Male mantids significantly preferred females that were eating a prey. In all cases choices were made after the females consumed the whole prey. This suggests that males did not use the prey as a direct way to avoid being cannibalized by keeping the female busy. The preference for females that had recently fed may have evolved because of the potential reduction in sexual cannibalism. Copyright © 2016 Elsevier B.V. All rights reserved.

    Partner-focused petitionary prayer (PFPP) has received little attention in the prayer literature. In two studies, we examine PFPP to see whether it is uniquely important in conveying relationship benefits, whether its benefits are transmitted through an effect on relationship satisfaction, and whether one's own or the partner's PFPP is central to beneficial effects. In Study 1, we examined PFPP in a sample of 316 undergraduate students who were in an "exclusive" romantic relationship, finding that PFPP was related to later level of commitment and that this relationship was partially mediated through enhanced relationship satisfaction. Study 2 examined PFPP in a sample of 205, married African American couples, finding that both partners' PFPP was consequential for commitment, with actor effects partially mediated through relationship quality, and partner effects fully mediated. Together the studies suggest the value of continued investigation of PFPP as a potentially important vehicle for enhancing relationship outcomes.

Participants were 185 community-dwelling African American women 25 to 85 years of age. Results indicated the women believed that mental illness is caused by several factors, including family-related stress and social stress due to racism, is cyclical, and has serious consequences but can be controlled by treatment. Participants endorsed low perceptions of stigma. Major preferred coping strategies included praying and seeking medical and mental health care. Age differences were found in all variables except stigma.

    To characterize the perception of Ebola virus disease (EVD) in Guinea, we administered, from November 2014 to February 2015, a questionnaire to a convenience sample of 200 lay people in Conakry and a group of 8 physicians. We found widespread misconceptions among lay people, including that praying to God can protect against EVD, that traditional healers are more competent than physicians in treating EVD, that people get infected through physical proximity without contact, that the Ebola epidemic is the result of Western bioterrorism experiments, that Western medical staff disseminated the virus, and that the purpose of quarantine measures is to hasten the death of Ebola patients. Major educational interventions, sensitive to local cultural beliefs, are needed to overcome the misconceptions about Ebola in Guinea.

    There is this tendency to think there s only one way to get from A to B. It turns out there are an infinite number of ways to get from point A to point B. What may work on one pro.ject may not work very well on another project for a variety of reasons. The lesson I've learned is that while it s good to have a road map, you have to realize the map is good for today, but it may change tomorrow, and it may change again the nest day. Use thc schedule as a too1 and he flexible, if you can. Cultivate a great team, take advantage of their experience, and pray for good luck.

  1. The Effect of Female Quality on Male Ejaculatory Expenditure and Reproductive Success in a Praying Mantid

    2015-01-01

    Strategic ejaculation is a behavioural strategy shown by many animals as a response to sperm competition and/or as a potential mechanism of cryptic male choice. Males invest more mating resources when the risk of sperm competition increases or they invest more in high quality females to maximize their reproductive output. We tested this hypothesis in the false garden mantid Pseudomantis albofimbriata, where females are capable of multiply mating and body condition is an indicator of potential reproductive fitness. We predicted male mantids would ejaculate strategically by allocating more sperm to high quality females. To determine if and how males alter their ejaculate in response to mate quality, we manipulated female food quantity so that females were either in good condition with many eggs (i.e. high quality) or poor condition with few eggs (i.e. low quality). Half of the females from each treatment were used in mating trials in which transferred sperm was counted before fertilisation occurred and the other half of females were used in mating trials where fertilisation occurred and ootheca mass and total eggs in the ootheca were recorded. Opposed to our predictions, the total number of sperm and the proportion of viable sperm transferred did not vary significantly between female treatments. Male reproductive success was entirely dependent on female quality/fecundity, rather than on the number of sperm transferred. These results suggest that female quality is not a major factor influencing postcopulatory male mating strategies in P. albofimbriata, and that sperm number has little effect on male reproductive success in a single mating scenario.

    By witchcraft, it refers to the activities of imagining and intending to affect or control the object through"supernatural power". Ancient witchcraft was applied extensively in which those applied for medical purpose included sorcery, praying, superstitious art of anti-disaster, and tabooing, were collectively called"medical witchcraft". During the Qin-Han periods, witchcraft was transformed by the theory of Yin-Yang and Five-Phases as a part of technical profession. Among them, the system of demon-ghost witchcraft was replaced by the necromantic ghost system; exorcism and taboo system were infiltrated with the conception of the art of mathematics and technical system; whereas the superstitious art of anti-disaster was replaced by incantation. The remnants of medical witchcraft not yet totally transformed were also applied by the technical professionals of the Qin-Han Dynasties.

    The results of the researches of spices-specificity, accumulation dynamics and distribution of 90Sr, of 137Cs and of transuranic elements in fish of the Chernobyl NPP exclusion zone are analysed. The data of estimations of absorbed doze rate from incorporated radionuclides for pray fish and predatory species are given. For the fish from the lake of the left-bank floodplain of the Pripyat River the increase of 90Sr specific activity is registered which is presumably connected with the dynamics of the physical-chemical forms of the radionuclide in soils and their wash out in water bodies from the catchment basin. Now about 90% of internal dose rate of fish from closed aquatic ecosystems within the Chernobyl NPP exclusion zone is caused by 90Sr incorporation.

    Showstack, Randy

    Twenty-seven subway cars lined on a barge awaited their fate off the coast of Delaware, about 26 kilometers east of the Indian River Inlet, on August 22.A priest blessed the dark-red cars donated by the New York City Transit Authority, and prayed for the safety of all creatures using them. The song, “Sidewalks of New York” filled the festivities: “East side, west side, all around the town…” A woman tossed tokens from those subway lines into the sea. Then, down went the cars, having first been scrubbed clean, with windows removed for better circulation. Shoved by a bulldozer, the cars were deployed in 35 minutes to join a heap of military vehicles, old tires, and other used materials already accumulated at Reef Site 11, a 1.3-square-nautical-mile artificial reef.

    1995-06-01

    Subsequent to a severe injury and under the influence of religious reading, Loyola experienced a dramatic mental change in his spiritual values in the sense of a sublimation to an alternative knighthood. His behaviour patterns observed thereafter were determined by a totality of his attachment to God. Based on this certainty in his faith, which was free from any doubts, and on God, and with the background of fasting and praying, he had visionary and pseudo-hallucinatory experiences. As the founder of an order and head of the community of Jesuits, Ignatius of Loyola proved to be diplomatically highly talented. There is no evidence of any psychotic disease. Also, there is no probability of a personality disorder in the sense of a neurosis. The numerous unusual behaviour patterns of Ignatius cannot be interpreted as psychopathological symptoms. It is justified to call him a genius.

    Objective Few studies examine how older adults' health status affects spiritual and religious involvement. This study examined the effects of gender and poor cardiac health on older adults' ends, means, and quest religious motivations and frequency of private devotion. Method Longitudinal data (12 months between the T1 and T2 interviews) with 182 older adults sampled from a Northeast city were used to examine in a multivariate analysis of covariance whether gender and the existence of cardiac health problems at T1 affected older adults' spiritual and religious involvement at T2. Findings A gender and cardiac health condition interaction showed older men with heart trouble had more changes in religious involvement-they engaged in more religious doubt, prayed less, and were not as intrinsically oriented at T2. Discussion The findings strongly suggest that older men with heart trouble may maintain a masculine style and shun seeking divine help.

  14. Should academic medical centers conduct clinical trials of the efficacy of intercessory prayer?

    2001-08-01

    Intercessory prayers for health or healing are requests to an object of worship for the preservation or restoration of health. There has been a recent proliferation of clinical trials that compare the health outcome of a group of prayed-for patients with that of controls, to test the efficacy of intercessory prayer. In this essay, the author defines the concept of intercessory prayer, contrasts it with other forms of prayer, and reviews the literature concerning clinical trials of its efficacy. The arguments put forward in favor of conducting such trials and those against are described and the reader is invited to consider their relative merits. The author concludes by discussing the potential power of faith in healing, reviewing the philosophical basis and pitfalls of clinical trials of intercessory prayer, and urging readers to weigh the arguments for and against such trials in academic medicine.

    Our primary agenda for the 21st Century is the reinvention of America. We must reinvent democracy, capitalism, entrepreneurism, and community. Indeed, we must recreate all of our major social institutions. This includes health care. A design for a new society requires a new design for health care. In fact, health care enjoys a special privilege in this regard. It is the gateway to total societal redesign. Health is the common denominator in any society. If you loose your health you cannot work, you cannot play, you cannot study; and, if you lose it sufficiently, you cannot even pray. Health and well-being create the foundation for all other constructive human endeavors. Therefore, the design of healthy communities is the necessary first step in the redesign of total human habitats. This massive redesign effort will take a century. However, it will be launched in the next few years.

    The growth of PACS (Picture Archiving and Communications System) market in Korea over the past 10 years is a brilliant development. In order to reach these brilliant achievements, the efforts of the Korean Society of PACS, the supports of the government on the information technology industry and the efforts of PACS companies in market expansion were all served as vital manures of the sowing time. By the end of 2001, 21% of the total Korean hospitals were under the clinical operation using filmless full PACS and it is believed to be the first incident in the world. The purpose of this paper is to look back upon the growing process of filmless PACS in Korea and analyze the cause of this tremendous growth. I believe that the Korean PACS experience would be helpful to many PACS experts who pray for a proliferation of PACS distribution.

    Elasmus steffani (Viggiani) (Hymenoptera: Elasmidae) is a gregarious idiobiont ectoparasitoid of Prays oleae (Bernard) (Lepidoptera: Plutellidae), an olive crop pest. In the substitute host Ephestia kuehniella (Zeller) (Lepidoptera: Pyralidae), the duration of the developmental stages was approximately 11–15 days. The preoviposition was 8.9 ± 5.0 days, and oviposition lasted 30.4 ± 10.5 days, with a reproduction capacity of 185.5 ± 62.3 eggs per female, for a mean of 5.4 ± 0.9 eggs per day. The oviposition rhythm reached its maximum when the parasitoid was 35 days of age. The lack of food negatively influenced survival of the adults, while those fed on a honey-water mixture lived significantly longer that those that also had access to a host as food. The female parasitoid fed upon 15% of the paralyzed larvae. The virgin female E. steffani exhibits arrhenotokic parthenogenesis. PMID:20874600

    To explore the lived experiences of adolescents with sickle cell disease, in Kingston, Jamaica. A descriptive qualitative design was used for this research. In-depth interviews were conducted with six adolescents with sickle cell disease at a Sickle Cell Unit operated by the University of the West Indies. Interviews were audiotaped, transcribed, and thematically analyzed. The majority of the adolescents demonstrated a positive self-concept. They reported strong family, school, and peer support which made them feel accepted. All were actively engaged in social activities such as parties, but had challenges participating in sporting activities. Various coping strategies were utilized to address challenges of the disease including praying, watching television, and surfing the Internet. Sickle cell disease can be very challenging for the adolescent, but with positive self-concept and increased social support, especially from family and peers, these adolescents were able to effectively cope with their condition and live productive lives.

    2013-09-01

    The more death is studied, the more it remains a mystery. Dealing with death is no easy matter and for that reason it is so frightening. All the fears of human beings are fundamentally related to the fear of death. This is because it is a mystery about which we know little or nothing, although it is natural to die. In view of this, religions give this topic a primary focus. Therefore, in this article an attempt is made to deal with the taboo surrounding death and reflect on issues associated with it. These themes are present in people's lives, especially when they have the experience of losing someone in their family or circle of friends. Among these subjects, the aspects of the Anointing of the Sick, the Funeral Mass, the Seventh Day Mass and the tradition of praying for the dead are all touched upon. These are all themes that help to deal with the taboo of death or losing a loved one.

    After battle, the moral and mortality stresses influence different soldiers in different ways. Using two large-scale surveys of World War II veterans, this research investigates the impact of combat on religiosity. Study 1 shows that as combat became more frightening, the percentage of soldiers who reported praying rose from 42 to 72%. Study 2 shows that 50 years later, many soldiers still exhibited religious behavior, but it varied by their war experience. Soldiers who faced heavy combat (vs. no combat) attended church 21% more often if they claimed their war experience was negative, but those who claimed their experience was positive attended 26% less often. The more a combat veteran disliked the war, the more religious they were 50 years later. While implications for counselors, clergy, support groups, and health practitioners are outlined, saying there are no atheists in foxholes may be less of an argument against atheism than it is against foxholes.

    Wudu’ (Ablution) workstation is one of the facilities used by most Muslims in all categories. At present, there are numbers of design guidelines for praying facilities but still lacking on wudu’ (ablution) area specification especially or elderly. Thus, It is timely to develop an ergonomic wudu’ workstation for elderly to perform ablution independently and confidently. This study was conducted to design an ergonomic ablution unit for the Muslim’s elderly in Malaysia. An ablution workstation was designed based on elderly anthropometric dimensions and was then analyse using CATIA V5R21 for posture investigation using RULAs. The results of the study has identified significant anthropometric dimensions in designing wudu’ (ablution) workstation for elderly people. This study can be considered as preliminary study for the development of an ergonomic ablution design for elderly. This effort will become one of the significant social contributions to our elderly population in developing our nation holistically.

    Prayer marks (PMs) are commonly occurring dermatologic changes in muslims who pray and develop over a long period of time as a consequence of repeated and extended pressure. PMs need careful examination especially for patients with diabetes, who are more vulnerable due to predisposing factors such as venous insufficiency and peripheral neuropathy. A total of 166 patients with diabetes (150 males, 16 females) and 65 normal subjects from Bangladesh were examined for the appearance of PMs. Twenty-eight patients (16.9 %) and one normal subject (1.5 %) had PMs. The marks were not itchy or painful and they were observed on the dorsal aspect of the left foot, which was attributed to a more typical prayer position that placed pressure on the left foot. PMs are not a rare clinical entity among muslim patients with diabetes and most clinicians should be aware of it as it can be the predominant cause of an ulcer.

    Background The aim of this study was to determine the status of utilizing some complementary and alternative medicine techniques in infertile couples. Methods This was a cross-sectional study conducted on 250 infertile couples referred to a hospital in Kerman using convenience sampling. A researcher-made questionnaire was used to study the prevalence and user satisfaction of complementary and alternative medicines. Results Results indicated that 49.6% of the infertile couples used at least one of the complementary and alternative medicines during the past year. Most individuals used spiritual techniques (71.8% used praying and 70.2% used Nazr) and medicinal plants (54.8%). Safety is the most important factor affecting the satisfaction of infertile couples with complementary treatments (couples think that such treatments are safe (54.8%)). Discussion Concerning high prevalence of complementary and alternative treatments in infertile couples, incorporating such treatments into the healthcare education and promoting the awareness of infertile individuals seem crucial.

    We report the preparation of a specific fibroin antibody and its use for the identification of unearthed ancient silk relics. Based on the 12-amino-acid repeat sequence "GAGAGSGAGAGS", which is found in fibroin of the silkworm Bombyx mori, a specific antibody against fibroin was prepared in rabbits through peptide synthesis and carrier-protein coupling. This antibody was highly specific for fibroin found in silk. Using this antibody we have successfully identified four silk samples from different time periods. Our results reveal, for the first time, a method capable of detecting silk from a few milligrams of archaeological fabric that has been buried for thousands of years, confirming that the ancient practice of wearing silk products while praying for rebirth dated back to at least 400 BCE. This method also complements current approaches in silk detection, especially for the characterization of poorly preserved silks, promoting the investigation of silk origins and of ancient clothing cultures.

    Sharia compliant wheelchair wheel cleaner was developed in order to assist the muslim Person with Disabilities (PWD) to pray in the mosque without leaving their wheelchair because of the filthy wheels. Though there are many wheelchair wheel cleaning system in the market, it is very rare to find sharia compliant cleaning system that applies sertu concept which is one of the cleaning and purification technique in Islamic practice. The sertu concept is based on 6:1 ratio that refers to the six times pipe water cleaning and one time soiled water cleaning. The development process consists of design stage, fabrication and system installation stage and followed by testing stage. During the design stage, the proposed prototype underwent design brainstorming, operation programming and structural simulation analysis. Once fabricated, the cleaner prototype underwent was tested. The results showed that the prototype can cater load up to 100kg with 1.31×10-6 mm shaft bending displacement. The water ejection timing varied approximately 3% compared to the program.

    We hypothesized that spiritual distress was a common, unrecognized theme for neonatal intensive care unit (NICU) care providers. An anonymous questionnaire form assigned to a data table in a relational database was designed. Surveys were completed by 66% of NICU staff. All respondents viewed a family's spiritual and religious concerns as having a place in patient care. Eighty-three percent reported praying for babies privately. Asked what theological sense they made of suffering of NICU babies, 2% replied that children do not suffer in the NICU. Regarding psychological suffering of families, the majority felt God could prevent this, with parents differing (p = 0.039) from nonparents. There exists a strong undercurrent of spirituality and religiosity in the study NICU. These data document actual religious and spiritual attitudes and practices and support a need for pastoral resources for both families and care providers. NICU care providers approach difficulties of their work potentially within a religious and spiritual rather than a uniquely secular framework.

  7. Qibla in the Mediterranean

    NASA Astrophysics Data System (ADS)

    Rius-Piniés, Mònica

    Orientation toward Mecca has been compulsory for Muslims in all time periods and in all places. In fact, mosques were built in such a way as to help believers to pray toward the right direction. Nevertheless, the alignment of the sacred buildings was not always exact, and many did not actually face the Kaaba. There are many reasons for this "mistake", the main one being that at the time of the construction of the most important mosques, the astronomical and geographical knowledge needed to make accurate calculations was lacking. In the Mediterranean area, the scholars who were most involved in this task were the fuqahā' (experts in Islamic jurisprudence) who were sometimes well versed in astronomical knowledge or, at least, were skilled in the practice of popular astronomy. The combination of astronomy and religion, mixed with the political and topographical conditions, produces a unique area of study which remains controversial today.

    The purpose of this study was to evaluate a conceptual model that assesses whether praying to the saints or the Virgin is associated with the health of older Mexican Americans. A survey was conducted of 1,005 older Mexican Americans (Mean age = 73.9 years; SD = 6.6 years). Data from 795 of the Catholic respondents are presented in this study. The findings support the following relationships that are embedded in the conceptual model: (1) older Mexican Americans who attend church more often are more likely to believe in the efficacy of prayer to the saints or the Virgin; (2) stronger beliefs in the efficacy of intercessory prayer are associated with more frequent prayer to the saints or the Virgin; (3) frequent prayer is to the saints or the Virgin is associated with greater God-mediated control beliefs; (4) stronger God-mediated control beliefs are associated with greater optimism; and (5) greater optimism is associated with better self-rated health.

    Muslims perform the prayers facing towards the correct qibla direction would be the only one of the practical issues in linking theoretical studies with practice. The concept of facing towards the Kaaba in Mecca during the prayers has long been the source of controversy among the muslim communities to not only in poor and developing countries but also in developed countries. The aims of this study were to analyse the geodetic azimuths of qibla calculated using three different models of the Earth. The use of ellipsoidal model of the Earth could be the best method for determining the accurate direction of Kaaba from anywhere on the Earth's surface. A muslim cannot direct himself towards the qibla correctly if he cannot see the Kaaba due to setting out process and certain motions during the prayer this can significantly shift the qibla direction from the actual position of the Kaaba. The requirement of muslim prayed facing towards the Kaaba is more as spiritual prerequisite rather than physical evidence.

    This study examined spiritual coping mechanisms, beliefs about spirituality and participation in spiritual activities and in other positive activities among adolescents in foster care. A multidimensional measure of spirituality was developed for face-to-face interviews with 188 youth (ages 14-17) from diverse racial/ethnic backgrounds in the United States. Findings revealed 95% of youth believe in God, over 70% believe God is 'creator' and God is 'love', and 79% considered prayer a spiritual practice. Most youth said love and forgiveness help them heal. Two-thirds (67%) reported responding to 'bad or tragic things happening' by spending time alone, and over half responded by praying (59%) or sharing the problem with someone else (56%). Youth's top three spiritual goals were to follow God's plan for them, become a better person, and know their purpose in life. Based on the value youth ascribed to spiritual coping mechanisms, recommendations for policy and practice focus on the integration of spirituality into practice and caregiving for youth in foster care.

    Understanding the origin and diversification of organisms requires a good phylogenetic estimate of their age and diversification rates. This estimate can be difficult to obtain when samples are limited and fossil records are disputed, as in Dictyoptera. To choose among competing hypotheses of origin for dictyopteran suborders, we root a phylogenetic analysis (~800 taxa, 10 kbp) within a large selection of outgroups and calibrate datings with fossils attributed to lineages with clear synapomorphies. We find the following topology: (mantises, (other cockroaches, (Cryptocercidae, termites)). Our datings suggest that crown-Dictyoptera—and stem-mantises—would date back to the Late Carboniferous (~ 300 Mya), a result compatible with the oldest putative fossil of stem-dictyoptera. Crown-mantises, however, would be much more recent (~ 200 Mya; Triassic/Jurassic boundary). This pattern (i.e., old origin and more recent diversification) suggests a scenario of replacement in carnivory among polyneopterous insects. The most recent common ancestor of (cockroaches + termites) would date back to the Permian (~275 Mya), which contradicts the hypothesis of a Devonian origin of cockroaches. Stem-termites would date back to the Triassic/Jurassic boundary, which refutes a Triassic origin. We suggest directions in extant and extinct species sampling to sharpen this chronological framework and dictyopteran evolutionary studies. PMID:26200914

    It is reported that flood events will increase due to variability and change in climate, thus increasing the number of people exposed to flooding disasters. This exposure negatively impacts rural households' livelihoods. Women, men, young, old has distinctive vulnerability and this shapes the choice of flood adaptation strategies. This calls for a need to adopt group specific interventions to strengthen local adaptive capacity to flooding for the affected population. The purpose of this case study was to determine the adaptation strategies to floods adopted by rural households in the Zambezi region of Namibia and Mwandi district of Zambia. The study further examined how gender and age influenced the choice of different adaptation strategies. Six focus group meetings and a questionnaire survey of 207 randomly sampled households were conducted in the flood prone areas of the study. Descriptive statistics results on the adaptation strategies indicated that a majority of the households in Namibia learnt to live with floods (86%),practiced mafisa cattle trade (86%), flood water harvesting (68%), practiced early and late planting (63%), prayed (55%), practiced conservation agriculture (54%) and fish farming (53%). In Zambia the adaptation strategies were; conservation agriculture (91%), acquiring better skills on preparedness (66%), flood water harvesting (63%), praying (60%), and flood proofing (52%). Logistic regression analysis showed that age positively and significantly influenced the likelihood of taking up adaptation strategies such as tree planting, relocation to higher ground, flood water harvesting, early and late planting. The older the respondents the more likely they were to adopt the strategies mentioned. More young ones were more likely to adopt acquiring better skills on flood preparedness and mafisa cattle trading than the old ones. Gender positively and significantly influenced mafisa cattle trade (p<0.01), male headed households were more likely to

    Human body is a biological, open system and maintains itself in the changing environment. Disease state is cured by many medicinal systems for healing. Esoteric healing (through introspective hypnosis, meditation and spiritual intercession) is the system where its believers regard Supreme Being as Omnipotent, Omnipresent and Omniscient. Such persons take ill health as a boon and pray through meditation that He may by His Mercy grant health or if God wishes otherwise, they happily accept it so that they keep moving ahead on their spiritual path. This study is a review of literature, where results clearly point towards better psychological and spiritual healing in patients who believe in esoteric cures. Modern science in terms of cognitive psychology or neurophysiology has begun to emphasize the role of consciousness but, that is confined only to the physical world. It is only with the advent of Param Purush Puran Dhani Soami Ji Maharaj (200 years ago) that in the religion of Saints, the ultimate consciousness or the Super Consciousness of the highest order has been revealed.

  14. Effect of non-crop vegetation types on conservation biological control of pests in olive groves

    2013-01-01

    Conservation biological control (CBC) is an environmentally sound potential alternative to the use of chemical insecticides. It involves modifications of the environment to promote natural enemy activity on pests. Despite many CBC studies increasing abundance of natural enemies, there are far fewer demonstrations of reduced pest density and very little work has been conducted in olive crops. In this study we investigated the effects of four forms of non-crop vegetation on the abundance of two important pests: the olive psyllid (Euphyllura olivina) and the olive moth (Prays oleae). Areas of herbaceous vegetation and areas of woody vegetation near olive crops, and smaller patches of woody vegetation within olive groves, decreased pest abundance in the crop. Inter-row ground covers that are known to increase the abundance of some predators and parasitoids had no effect on the pests, possibly as a result of lack of synchrony between pests and natural enemies, lack of specificity or intra-guild predation. This study identifies examples of the right types of diversity for use in conservation biological control in olive production systems. PMID:23904994

    Puerto Ricans have been found to have higher asthma prevalence rates than non-Hispanic whites, blacks, and all other Hispanic subgroups. They also have the highest rates of emergency department (ED) use for the management of their asthma. Using a hermeneutic phenomenological approach, the aim of this study was to describe the lived experience of Puerto Rican families caring for their child's asthma and using the ED for asthma care. Six themes were generated from in-depth interviews with 10 Puerto-Rican caregivers: (1) The Folklore of Asthma, (2) Culture and the Medicine Woman, (3) In Awe of Asthma, (4) Praying to God, (5) The Decision-Time to Go, and (6) The ED Environment. The findings emphasize the necessity of establishing and maintaining a therapeutic partnership between primary care providers and families of children with asthma. The results may be used as a foundation for understanding motivations for seeking asthma care in the ED. Copyright © 2012 National Association of Pediatric Nurse Practitioners.

    The sanitation issue is entering the development discussion and the UN proclaimed 2008 the year of sanitation. The study aims to understand the cultural-spatial dimension among Muslim communities of excreting and recirculating human excreta in North West Frontier Province in Pakistan. Information on local perceptions and cultural understanding was collected through interviews, group discussions and observations in four selected villages. The study identifies a diversity of excreting practices among age groups and sexes, and varied adherence to expressed cultural norms. Interviewees express less resentment towards urine compared to faeces, however, their negative attitude subsides when faecal matter is mixed with water since this changes appearance, odour-and cultural meaning. Religious dictums about excreta and sewage accommodate contradicting routine behaviours to cater for needs of residents and farmers. For example, when mothers pray wearing soiled clothing, and in the use of wastewater as fertiliser for food production. The excreta-related practices are compatible with good hygienic behaviour as outlined by WHO Guidelines, except for children who are allowed to defecate anywhere. Copyright © 2010 Elsevier Ltd.

    Here we reconstruct the evolutionary shift towards floral simulation in orchid mantises and suggest female predatory selection as the likely driving force behind the development of extreme sexual size dimorphism. Through analysis of body size data and phylogenetic modelling of trait evolution, we recovered an ancestral shift towards sexual dimorphisms in both size and appearance in a lineage of flower-associated praying mantises. Sedentary female flower mantises dramatically increased in size prior to a transition from camouflaged, ambush predation to a floral simulation strategy, gaining access to, and visually attracting, a novel resource: large pollinating insects. Male flower mantises, however, remained small and mobile to facilitate mate-finding and reproductive success, consistent with ancestral male life strategy. Although moderate sexual size dimorphisms are common in many arthropod lineages, the predominant explanation is female size increase for increased fecundity. However, sex-dependent selective pressures acting outside of female fecundity have been suggested as mechanisms behind niche dimorphisms. Our hypothesised role of predatory selection acting on females to generate both extreme sexual size dimorphism coupled with niche dimorphism is novel among arthropods.

    The study examined associations between religious variables and alcohol abuse and dependence among 2,969 North Carolina residents aged 18 to 97 who participated in the 1983-1984 National Institute of Mental Health Epidemiologic Catchment Area survey at its Piedmont location. Six-month and lifetime prevalence of alcohol disorders were compared among participants reporting varying levels of religious activity. Data were collected on frequency of Bible reading, prayer, and church attendance; time spent watching or listening to religious programming on television or radio; importance of religion; religious denomination; and identification as "born-again" Christians. Recent and lifetime alcohol disorders were less common among weekly churchgoers and those who considered themselves born again. Recent, but not lifetime, alcohol disorders were also less common among respondents who frequently read the Bible or prayed privately. Alcohol disorders were more common among those who frequently watched or listened to religious television and radio. Lifetime, but not recent, alcohol disorders were more prevalent among members of Pentecostal denominations. Longitudinal study is necessary to further clarify and explain these relationships between religious practices and alcohol disorders.

    Four methodologically diverse studies (N = 1,758) show that prayer frequency and alcohol consumption are negatively related. In Study 1 (n = 824), we used a cross-sectional design and found that higher prayer frequency was related to lower alcohol consumption and problematic drinking behavior. Study 2 (n = 702) used a longitudinal design and found that more frequent prayer at Time 1 predicted less alcohol consumption and problematic drinking behavior at Time 2, and this relationship held when controlling for baseline levels of drinking and prayer. In Study 3 (n = 117), we used an experimental design to test for a causal relationship between prayer frequency and alcohol consumption. Participants assigned to pray every day (either an undirected prayer or a prayer for a relationship partner) for 4 weeks drank about half as much alcohol at the conclusion of the study as control participants. Study 4 (n = 115) replicated the findings of Study 3, as prayer again reduced drinking by about half. These findings are discussed in terms of prayer as reducing drinking motives.

    Very few studies have examined the effects of both religious affiliation and religiosity on mortality at the same time, and studies employing multiple dimensions of religiosity other than religious attendance are rare. Using the newly created General Social Survey-National Death Index data, our report contributes to the religion and mortality literature by examining religious affiliation and religiosity at the same time. Compared to Mainline Protestants, Catholics, Jews, and other religious groups have lower risk of death, but Black Protestants, Evangelical Protestants, and even those with no religious affiliation are not different from Mainline Protestants. While our study is consistent with previous findings that religious attendance leads to a reduction in mortality, we did not find other religious measures, such as strength of religious affiliation, frequency of praying, belief in an afterlife, and belief in God to be associated with mortality. We also find interaction effects between religious affiliation and attendance. The lowest mortality of Jews and other religious groups is more apparent for those with lower religious attendance. Thus, our result may emphasize the need for other research to focus on the effects of religious group and religious attendance on mortality at the same time.

    Evidence-based descriptions of culturally competent psychiatric nursing care are scarce. This study explored the perceptions of clients with mental illness regarding the overall effectiveness of psychiatric nursing care in meeting their cultural needs, and psychiatric nurses' perceptions of how and to what extent they provided culturally competent psychiatric mental health nursing care to diverse client populations. This descriptive study employed a qualitative research design using a multi-method data collection approach consisting of in-depth individual client interviews and a self-administered nurse questionnaire. Client participants tended to minimize the importance of receiving care related to their cultural needs. They described (1) encouraging and reassuring me; (2) speaking up for me; and (3) praying a lot as essential to their care. Nurse participants perceived their psychiatric nursing care to be culturally competent; however, few described specific strategies for incorporating cultural beliefs and practices into nursing care. Client participant lacked awareness of their cultural needs and had difficulty identifying and describing specific nursing interventions that contributed to positive mental health outcomes. Nurses perceived that they provided culturally competent care but actually lacked specific knowledge and skills to do so effectively. © 2010 Blackwell Publishing.

    As women recover from the experience of breast cancer and its treatment, it is important for them to find meaning in their lives and to understand their experiences from a holistic perspective. This study was designed to provide additional information about how women and their experiences recovering from breast cancer. The specific purpose was to describe the relationship between self-transcendence and spiritual well-being, and to identify the spiritual practices used by older women recovering from breast cancer. The theoretical framework for this study was Reed's theory of self-transcendence. A total of 87 community-residing women who had been diagnosed with breast cancer within the past 5 years participated in the study. There was a significant positive relationship between self-transcendence and spiritual well-being. The women used a mean of 9.72 spiritual practices with the most frequent being exercise, visiting a house of worship, and praying alone. The study results provide further support for the theory of self-transcendence. Future research recommendations are to expand the research to include a larger, more diverse group of women of all ages and backgrounds who have been diagnosed with breast cancer.

  5. Water management by early people in the Yucatan, Mexico

    The Yucatan Peninsula is a coastal plain underlain by permeable limestone and receives abundant rainfall. Such hydrogeologic conditions should provide major supplies of water; however, factors of climate and hydrogeology have combined to form a hydrologic system with chemical boundaries that limits the amount of fresh water available. Management of water resources has long had a major influence on the cultural and economic development of the Yucatan. The Mayan culture of the northern Yucatan developed on extensive use of groundwater. The religion was water oriented and the Mayan priests prayed to Chac, the water god, for assistance in water management, primarily to decrease the severity of droughts. The Spaniards arrived in 1517 and augmented the supply by digging wells, which remained the common practice for more than 300 years. Many wells now have been abandoned because of serious problems of pollution. A historical perspective of a paper such as this provides insight into the attitudes concerning water of early people and perhaps provides insight into current attitudes concerning water. Hydrogeologists possess the expertise to generate relevant information required by water managers to arrive at management programs to achieve sustainable development. ?? 1995 Springer-Verlag.

    Secondary school girls, ages 15 - 19 yrs were surveyed to find out the coping strategies they used when stressed. Adolescents, who are affected with stress and depression early in life, suffer from depression throughout their lives especially if they are utilizing improper ways to cope with it. A cross sectional school based survey among 1028 adolescent girls was conducted among the secondary schools in Riyadh city,Kingdom of Saudi Arabia. About 25% stated that they cry, 19% listen to music, 15% start eating a lot, 12% sit alone/isolate themselves, 11% pray/read the Quran, 10% get into a verbal argument or a fight. Only a few, 3% exercise, and 2% stated that they find someone to discuss and talk to. Majority of the adolescent girls in our survey, rely on emotion related coping mechanisms rather than problem solving mechanisms. This can cause long term implications in these adolescents as there is an increased probability to develop depression later on in life. Policy makers need to implement strategies for early identification of stress and depression. Talking to friends and family can serve as an effective way to cope with stress.

  7. Listening to Nature's orchestra with peculiar ears

    Insects use hearing for the crucial tasks of communicating with conspecifics and avoiding predators. Although all are based on the same acoustic principles, the diversity of insect ears is staggering and instructive. For instance, a South African grasshopper demonstrates that hearing conspecific calls is possible over distances 1 km with ears that do not have tympana. Actually, these creatures have six pairs of ears that play different roles in behavior. In numerical contrast, praying mantises have just a single ear in the ventral midline. The ear is very effective at detecting ultrasonic bat cries. However, the bioacoustics of sound transduction by two tympana facing each other in a deep, narrow slit is a puzzle. Tachinid flies demonstrate that directional hearing at 5 kHz is possible with a pair of ears fused together to give a total size of 1 mm. The ears are under the fly's chin. Hawk moths have their ears built into their mouthparts and the tympanum is more like a hollow ball than the usual membrane. As an apt last example, cicada ears are actually part of the orchestra: their tympana function both in sound reception and sound production.

    Some eyespots are thought to deflect attack away from the vulnerable body, yet there is limited empirical evidence for this function and its adaptive advantage. Here, we demonstrate the conspicuous ventral hindwing eyespots found on Bicyclus anynana butterflies protect against invertebrate predators, specifically praying mantids. Wet season (WS) butterflies with larger, brighter eyespots were easier for mantids to detect, but more difficult to capture compared to dry season (DS) butterflies with small, dull eyespots. Mantids attacked the wing eyespots of WS butterflies more frequently resulting in greater butterfly survival and reproductive success. With a reciprocal eyespot transplant, we demonstrated the fitness benefits of eyespots were independent of butterfly behaviour. Regardless of whether the butterfly was WS or DS, large marginal eyespots pasted on the hindwings increased butterfly survival and successful oviposition during predation encounters. In previous studies, DS B. anynana experienced delayed detection by vertebrate predators, but both forms suffered low survival once detected. Our results suggest predator abundance, identity and phenology may all be important selective forces for B. anynana. Thus, reciprocal selection between invertebrate and vertebrate predators across seasons may contribute to the evolution of the B. anynana polyphenism. PMID:25392465

    The eggs of stick and leaf insects (Phasmatodea) bear strong resemblance to plant seeds and are commonly dispersed by females dropping them to the litter. Here we report a novel egg-deposition mode for Phasmatodea performed by an undescribed Vietnamese species of the enigmatic subfamily Korinninae that produces a complex egg case (ootheca), containing numerous eggs in a highly ordered arrangement. This novel egg-deposition mode is most reminiscent of egg cases produced by members of unrelated insect orders, e.g. by praying mantises (Mantodea) and tortoise beetles (Coleoptera: Cassidinae). Ootheca production constitutes a striking convergence and major transition in reproductive strategy among stick insects, viz. a shift from dispersal of individual eggs to elaborate egg concentration. Adaptive advantages of ootheca formation on arboreal substrate are likely related to protection against parasitoids and desiccation and to allocation of specific host plants. Our phylogenetic analysis of nuclear (28S, H3) and mitochondrial (COI, COII) genes recovered Korinninae as a subordinate taxon among the species-rich Necrosciinae with Asceles as sister taxon, thus suggesting that placement of single eggs on leaves by host plant specialists might be the evolutionary precursor of ootheca formation within stick insects.

    Religious addiction is a new behavioral addiction, featured with pathologic religious activity. The authors examined whether this new phenomenon appears in adolescence, and whether it correlates with substance use and mental health variables. The General Addiction Screening Tool was used to investigate the presence of religious addiction among youth (N = 656; mean age, 16.5 years; 49.2% females). Besides monthly and lifetime prevalence of substance use, variables of psychological well-being (e.g., depression, aggression, optimism) were also detected. Religiosity was relatively low among adolescents. Nearly 1% of the sample might be characterized as being addicted to religion, 16.2% belonged to the symptomatic group, while 83% of them were asymptomatic. Religious addicts were more likely to be more religious and the role of religion in one's life was more important. Also, they tended to pray more and attend church more frequently. It was also found that amphetamine use was more frequent among the addicts. In terms of mental health level, aggression scored lower and spiritual well-being reached higher level. Religiosity is a vague phenomenon, and further investigation is needed to detect when healthy enthusiastic religiosity turns into religious addiction.

    The hydrostratigraphic units of the Edwards and Trinity aquifers have been mapped and described herein using a classification system developed by Choquette and Pray (1970), which is based on porosity types being fabric or not-fabric selective. The naming of hydrostratigraphic units is also based on preexisting names and topographic or historical features that occur in outcrop. The only hydrostratigraphic unit of the Edwards aquifer present in the study area is VIII hydrostratigraphic unit. The mapped hydrostratigraphic units of the upper Trinity aquifer are, from top to bottom: the cavernous, Camp Bullis, upper evaporite, fossiliferous, and lower evaporite and they are interval equivalent to the upper member of the Glen Rose Limestone. The middle Trinity aquifer (interval equivalent to the lower member of the Glen Rose Limestone) contains, from top to bottom: the Bulverde, Little Blanco, Twin Sisters, Doeppenschmidt, Rust, and Honey Creek hydrostratigraphic units. The lower part of the middle Trinity aquifer is formed by the Hensell, Cow Creek, and Hammett hydrostratigraphic units which are interval equivalent to the Hensell Sand Member, the Cow Creek Limestone, and the Hammett Shale Member, respectively, of the Pearsall Formation.

    Five billion people lack access to safe, affordable, and timely surgical and anesthesia care. Significant challenges remain in the provision of surgical care in low-resource settings. Uganda is no exception. From September to November 2016, we conducted a mixed-methods countrywide surgical capacity assessment at 17 randomly selected public hospitals in Uganda. Researchers conducted 35 semi-structured interviews with key stakeholders to understand factors related to the provision of surgical care. The framework approach was used for thematic and explanatory data analysis. The Ugandan public health care sector continues to face significant challenges in the provision of safe, timely, and affordable surgical care. These challenges can be broadly grouped into preparedness and policy, service delivery, and the financial burden of surgical care. Hospital staff reported challenges including: (1) significant delays in accessing surgical care, compounded by a malfunctioning referral system; (2) critical workforce shortages; (3) operative capacity that is limited by inadequate infrastructure and overwhelmed by emergency and obstetric volume; (4) supply chain difficulties pertaining to provision of essential medications, equipment, supplies, and blood; (5) significant, variable, and sometimes catastrophic expenditures for surgical patients and their families; and (6) a lack of surgery-specific policies and priorities. Despite these challenges, innovative strategies are being used in the public to provide surgical care to those most in need. Barriers to the provision of surgical care are cross-cutting and involve constraints in infrastructure, service delivery, workforce, and financing. Understanding current strengths and shortfalls of Uganda's surgical system is a critical first step in developing effective, targeted policy and programming that will build and strengthen its surgical capacity.

    Spiritism is the third most common religion in Brazil, and its therapies have been used by millions worldwide. These therapies are based on therapeutic resources including prayer, laying on of hands, fluidotherapy (magnetized water), charity/volunteering, spirit education/moral values, and disobsession (spirit release therapy). This paper presents a systematic review of the current literature on the relationship among health outcomes and 6 predictors: prayer, laying on of hands, magnetized/fluidic water, charity/volunteering, spirit education (virtuous life and positive affect), and spirit release therapy. All articles were analyzed according to inclusion/exclusion criteria, Newcastle-Ottawa and Jadad score. At present, there is moderate to strong evidence that volunteering and positive affect are linked to better health outcomes. Furthermore, laying on of hands, virtuous life, and praying for oneself also seem to be associated to positive findings. Nevertheless, there is a lack of studies on magnetized water and spirit release therapy. In summary, science is indirectly demonstrating that some of these therapies can be associated to better health outcomes and that other therapies have been overlooked or poorly investigated. Further studies in this field could contribute to the disciplines of Complementary and Alternative Medicine by investigating the relationship between body, mind, and soul/spirit. PMID:21687790

    The study of droughts in the instrumental period can be based on various drought indices calculated usually from precipitation and temperature series. Documentary evidence, overlapping partly also with meteorological measurements, represents another important source utilisable particularly for the pre-instrumental period. Direct reports of drought or indirect indications of its impacts may be found in various individual or institutional sources: narrative written sources (annals, chronicles, commemorative records), weather diaries, personal and official correspondence, stall-keepers' and market songs, journalism, financial-economic records, religious sources (rogations, sermons, praying), special printed sources, chronograms, epigraphic sources ("hunger" stones). Corresponding data indicate directly meteorological drought and with describing of drought impacts also agricultural and hydrological droughts. The first credible direct drought information from the Czech Lands reports not any rain or snowfall during the 1090/1091 winter (Monk of Sázava). But data before AD 1500 are relatively scarce and they are related prevailingly to Bohemia. Density of precipitation/drought documentary records in the Czech Lands increases significantly after 1500. This allows create series of precipitation indices with classification of dry months in the scale -1 as dry, -2 as very dry and -3 as extremely dry month. Such dataset is important for the creation of 500-year Czech drought chronology.

    Many national organizations call for medical students to receive more public health education in medical school. Nonetheless, limited evidence exists about successful servicelearning programs that administer preventive health services in nonclinical settings. The Flu Crew program, started in 2001 at the Stanford University School of Medicine, provides preclinical medical students with opportunities to administer influenza immunizations in the local community. Medical students consider Flu Crew to be an important part of their medical education that cannot be learned in the classroom. Through delivering vaccines to where people live, eat, work, and pray, Flu Crew teaches medical students about patient care, preventive medicine, and population health needs. Additionally, Flu Crew allows students to work with several partners in the community in order to understand how various stakeholders improve the delivery of population health services. Flu Crew teaches students how to address common vaccination myths and provides insights into implementing public health interventions. This article describes the Stanford Flu Crew curriculum, outlines the planning needed to organize immunization events, shares findings from medical students' attitudes about population health, highlights the program's outcomes, and summarizes the lessons learned. This article suggests that Flu Crew is an example of one viable service-learning modality that supports influenza vaccinations in nonclinical settings while simultaneously benefiting future clinicians.

    : In the 5 years since the Sandy Hook elementary school shooting that claimed the lives of 20 children and 6 of their teachers, we have witnessed intolerably more mass shooting events. In the intervening years, over 150,000 Americans have died because of firearm violence, 3 times the number who lost their lives during the Revolutionary war. In the last 2 months, we have been left reflecting on 2 more tragedies. The first came on October 1 in Las Vegas, at the Route 91 music festival where 58 were killed and over 500 injured by a single gunman. The second, on November 5, took place in Sutherland Springs, Texas (population 600) near San Antonio and claimed the lives of 26 men women and children while they prayed. As was witnessed in Orlando and San Bernardino, these most recent mass casualty incidents strained first responders, law enforcement, and the state's trauma systems to their breaking point.Once again, we were left searching for the reasons behind these tragedies asking predictable questions: who did this and why? Was it part of a terrorist plot or a lone psychopath with a grudge? Were the weapons obtained legally, and why would anyone need so many? How can we stop this from happening again?

    The purpose of the current cross-sectional study was to test the associations between individual coping responses to pain, dyadic coping, and perceived social support, with a number of pain outcomes, including pain intensity, functional disability, and pain adjustment, in a sample of N = 43 patients suffering from chronic pain in Switzerland. In contrast to previous research, we were interested not only in specific pain coping but also in more general stress coping strategies and their potential influence on pain outcomes. Analyses were performed using correlation and regression analyses. “Praying and hoping” turned out to be an independent predictor of higher pain intensity and higher anxiety levels, whereas both “coping self-instructions” and “diverting attention” were associated with higher well-being, less feelings of helplessness, and less depression and anxiety. We further found a link between “focusing on and venting emotions” and “worse pain adjustment”. No significant relationship between dyadic coping and social support with any of our pain outcomes could be observed. Overall, our results indicate that individual coping strategies outweigh the effects of social support and dyadic coping on pain-related outcomes and pain adjustment. However, results need to be interpreted with caution given the small sample size. PMID:28331356

    The aim of the study was to investigate the beliefs and practices of caregivers and traditional healers within the South African Muslim community regarding Down syndrome. An exploratory-descriptive research design was utilized which incorporated individual interviews with 10 caregivers of persons with Down syndrome as well as 10 traditional healers from the South African Muslim community. Common beliefs emanating from both groups relating to the cause of Down syndrome included the notion that this condition was genetic in origin and that such children were perceived to be gifts from God. Others attributed Down syndrome to a punishment from God or the result of curses from people. Treatment included the use of inscriptions from the Quraan, water that had been prayed over and herbal medicines. Some caregivers seemed reluctant to approach western health care professionals due to negative past experiences. The main reasons for consulting traditional healers were cultural beliefs and pressure from family members, their holistic approach and the personal nature of their interventions. Collaboration between allopathic medicine and traditional healing was advocated by almost all of the traditional healers. These findings underline the need for culturally sensitive rehabilitation practices in speech-language pathology and audiology; and collaboration between western health care practitioners and traditional healers.

    Stagmatoptera Burmeister, 1838 includes medium to large-sized (49.8-98.7mm) praying mantises distributed in the Neotropical region. They are characterized for having a central, circular spot on each forewing, and 2-4 carinae in the head's frontal shield. This study is an updated revision of the genus on the basis of type and non-type material deposited in various scientific collections from Europe and the Americas. The following nomenclatural procedures were conducted: Stagmatoptera nova is a new junior synonym of Stagmatoptera pia, Stagmatoptera ignota as the junior synonym of Stagmatoptera femoralis, and Stagmatoptera flavipennis is reinstated as the junior synonym of Stagmatoptera supplicaria. Two new species are described: Stagmatoptera diana Rodrigues sp. n. from Colombia and Venezuela, and Stagmatoptera cerdai Rodrigues sp. n. from Trinidad & Tobago and Venezuela. Stagmatoptera now includes 14 species, two of which (Stagmatoptera abdominalis and Stagmatoptera indicator) are considered as species inquirenda. We provide detailed morphological descriptions of all species, a species-level identification key, in addition to abundant visual material to assist identification. Female genitalia, a structure seldom used for taxonomic purposes, was a useful character system to distinguish among species of the genus. Distribution maps for all species are also provided.

    The area of Baiturrahman Grand Mosque in Banda Aceh has a deep meaning for people of Aceh because it is a historical site, which has many historical heritages. Recently, it is rarely seen people walk along the corridor of the town. People always drive to move along the road and stop right on their destination. Some are still walking, but only for 20-30 meter. On the other hand, a number of the vehicle significantly increase followed by the needs of parking space. The intensity of the traffic is high in day time; in the morning, at noon, and in the late afternoon. The research will be conducted using qualitative and quantitative methods; investigating the change of the environment caused by development, disaster, and conflict, interviewing government as the decision maker and public figure, questionnaires, and finding information from official documents and literature. It is necessary to identify the determinant factors of no-pedestrian phenomenon in the area of Banda Aceh because it is expected to create atmosphere, which encourage people to walk along the city center, revive walking habits to urban community, and strengthen the role of city center as a center of activities; praying, shopping, and engaging in recreation and leisure.

    To determine the knowledge and practice of contraception among United Arab Emirates (UAE) women. Four hundred and fifty UAE women at risk of pregnancy were randomly selected from the community and primary health care centres and interviewed about knowledge and practice of contraception using a structured questionnaire. Four hundred women (89%) gave consent to participate in the study. One hundred and sixty-six participants (41.5%) were using contraception. All used natural methods backed with other methods. There were significant associations between using contraception and each of age, high level of education and low family income (p < 0.0001 for the three variables). Religious beliefs and low expectation of success of birth control were the reasons given for non-use. Eighty-five percent of subjects did not accept sterilisation without medical indications, nor using contraception before the first pregnancy. Of the women, 42.5% believed that contraceptive methods should not be used after the age of 40, and 78% were unaware that they could be used for treatment of gynaecological diseases. Disturbed bleeding patterns occurred in 48.7% of users, and these were most bothered by the inability to pray (100%) and to have sexual intercourse (97.5%). Contraception is not commonly used by UAE women because of sociocultural traditions, religious beliefs and poor knowledge.

    Activity patterns and perceptions play a key role in human health risk, management, and planning. A survey of 233 people attending a Native American festival in Cookeville Tennessee were interviewed to determine the types, percent participation, and outdoor activities rates, and their perceptions of the importance of characteristics of sites. The indicate that: 1) a high percentage of respondents used outdoor environments, 2) they used them for consumptive (hunting, fishing), non-consumptive (hiking, walking, bird-watching), and religious/sacred activities, 3) a higher percentage of respondents engaged in non-consumptive than consumptive activities, 4) praying or meditating, communing with nature, and bird-watching had the highest uses rates 5) the environmental characteristics rated the highest were lack of radionuclides that presented a health risk, no visible smog, clean air, and unpolluted water, 6) presence of people, buildings and roads were rated the lowest and 7) Native Americans had higher participation rates, participated more frequently, and evaluated environmental characteristics higher than did Caucasians. This information can be used by managers to create and maintain outdoor habitats that fit the needs of local people. Planning and management require information on public policy, human needs and requirements, and human perceptions and evaluations of environmental characteristics. PMID:23229153

    The present study offers a cross-cultural examination of the effect of prayer on forgiveness. American (n = 51) and Indian (n = 100) participants either prayed for their romantic partner (prayer condition) or described their romantic partner's physical attributes (control condition). Prayers were self-guided and lasted 3 minutes. Pre-test and post-test measures of retaliation were completed. Results showed that participants in the prayer group showed statistically significant decreases in retaliation motives from pre-test to post-test and the magnitude of this change was not different across cultures. Control groups in both cultures showed no change. Because of the religious diversity present in the Indian sample, the robustness of the effect of prayer on forgiveness was tested across Christian, Hindu and Muslim Indians. Religious affiliation did not moderate the effect of prayer on forgiveness in this sample. Results suggest that a brief prayer is capable of producing real change in forgiveness and this change is consistent across American and Indian cultures and across three different religious groups in India. Brief prayer for others that enhances forgiveness may be useful for individuals in close relationships, in certain counselling settings and for people in many different walks of life. © 2015 International Union of Psychological Science.

  6. The healing power of prayer and its implications for nursing.

    Prayer is widely acknowledged in both ancient and modern times as an intervention for alleviating illnesses and promoting good health. There is increasing attention on prayer in health care, in both popular and serious discourse. Advocates exalt the healing power of prayer in health care, while critics are sceptical about this claim and its healing potential is put down to coincidences or its placebo effect. Consequently, a variety of empirical studies have attempted to test its effect scientifically with no conclusive results. There is evidence to suggest that some patients and healthcare practitioners believe in the healing power of prayer. Nurses may be called upon to pray with or for patients as part of holistic care. This article sets out to explore the role of prayer in healing and its implications for nursing. To achieve this aim, this article provides a review of discourses and evidence on the power of prayer in healing. Its implications for nursing are highlighted with some suggestions on how to respond to patients' spiritual needs. It is concluded that, although the evidence on the healing power of spirituality is inconclusive, there are indications that it has potential for the health and wellbeing of both patients and nurses.

    Prayer is generally recognized as an important aspect of religiousness. Relatively few empiric studies examined the relation between prayer and depressive symptoms in later life, and findings so far are mixed. Respondents, aged 60-91 years, participated in the third (N = 1,702) and fourth (N = 1,346) assessment cycles, with three-year intervals, of the Longitudinal Aging Study Amsterdam. Data were collected on frequency of prayer, perceived meaningfulness of prayer, religious affiliation, church attendance, salience of religion, demographics, and health variables. Depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression Scale. In the total sample, there was no significant association between frequency of prayer and depressive symptoms. Among those who were not religiously affiliated, prayer was associated with higher levels of depressive symptoms. The results were particularly pronounced among nonaffiliated widowed respondents; odds ratio for praying daily associated with having Center for Epidemiologic Studies-Depression Scale scores of 16 and higher amounted to 3.59 (99% confidence interval: 1.01-11.79). At three-year follow up, prayer did not predict change of depressive symptoms. As secularization in Western Europe progresses, the current results suggest that clinical exploration of private religiousness among older patients remains relevant, also among people who seem to be less religious.

    It is still largely unknown which actions people take to improve their mood when they feel they are getting depressed. Using the five-factor model of personality, we explore coping actions in a population of older adults in residential homes in relation to personality traits. A total of 350 non-cognitively impaired inhabitants of residential homes in the Netherlands participated in this study (mean age 85 years). They indicated which of 22 actions to cope with depression they had used in the past three months, and which of these they considered to be helpful in reducing depression. Other measures included the NEO-FFI, CES-D and MINI. Almost 60% of all subjects had used one or more actions to reduce depression in the past three months, and almost 90% considered one or more actions to be helpful in reducing depression. People scoring high on neuroticism had used more coping actions, including relaxing, eating chocolate, praying, seeking professional help, engaging in more pleasant activities, and talking to friends and relatives. People scoring high on openness considered many of the actions to be helpful. We conclude that actions taken to cope with depression and their helpfulness differ considerably for subjects with differing personality traits.

    Contraceptive-induced vaginal bleeding changes may be an undesired side effect, or a welcome opportunity to alter menstrual patterns. In Europe and the US, such changes are increasingly accepted; this study explores the perceptions of women around the globe. Norplant users from five countries (Chile, China, the Dominican Republic, Indonesia and Tunisia; N = 486) were surveyed at entry into a contraceptive clinical trial regarding preferred frequency of menstruation, menses-associated symptoms, and activities during menses. Most women preferred once-monthly menstruation (81%); women in Chile, younger women, women neither married nor cohabitating, Christian women, and women experienced with hormonal contraception were more likely to accept alternative bleeding patterns. Women in Tunisia and Chile reported more symptoms associated with menses, while women in Beijing reported very few; decreased energy (32%), headaches (26%), abdominal pain (23%) and depression (22%) were most common. Avoidance of activities during menses such as physical work, sports, praying and entering religious sites, was closely tied to study centre. Across all sites, women (90%) avoided sexual intercourse during menses. Despite growing acceptance of altering bleeding patterns, women in this study preferred monthly vaginal bleeding. Understanding sociocultural contexts and individual preferences is important when addressing this issue with women from diverse backgrounds.

    Despite the high number of studies on family caregivers, there is little research on the impact of religiosity on formal caregiving (paid providers). We examine the role of religiousness in the mental health, quality of life and stress of nurse aides (NA) who provide care for patients in a nursing home. NA in a Brazilian nursing home were invited to participate. Because of its coping function, we hypothesized that religiousness was related to better mental health and quality of life. Linear regression was used to test this hypothesis and control for confounders. Compared with the Brazilian general population, NA scored higher on measures of religious involvement. Intrinsic religiosity was associated with better mental health and quality of life. Organizational religiosity was associated with better social functioning, better general mental health and fewer anxiety symptoms. Non-organizational religiosity (prayer), however, was associated with negative outcomes, such as higher stress, poorer general health perceptions and more anxiety symptoms. Most NA indicated that they had prayed for and with their patients. In conclusion, paid caregivers (NA) have a strong sense of religiousness, which plays an important role in many ways, including the type of care they provide, their mental health and their quality of life. © 2013 John Wiley & Sons Ltd.

    The family is the basic unit of any society and culture. The concept, structure, and function of the family unit vary considerably across different cultures; however, its role continues to be imperative to the development of individuals and their psychological make-up. All societies have a concept of 'family', its relative importance, structure, and functions; however, this varies according to the particular culture. In the Arabic culture, as well as other collectivistic cultures, the extended family is often regarded as the basic unit. The family is the foundational and basic social unit that fosters the stability, well-being and sustainability of society. The quality of family relationships shapes and influences the social, psychological, and biological development and functioning of its members. This may be especially relevant to individuals with mental health problems. The people of ancient Egypt valued family life highly, and this is the case even now. They treasured children and regarded them as a great blessing. If a couple had no children, they would pray to the gods and goddesses for help. They would also place letters at the tombs of dead relatives asking them to use their influence with the gods. The importance of family has not changed dramatically even though the structures are beginning to. In this paper we highlight changes in family set-up and the state of family therapy in Egypt.

    Millions of refugees are on the move globally, mostly settling in low- and middle-income (LMIC) "host" countries, where they often receive insufficient assistance and encounter a multitude of barriers. Despite a risk for developing mental illness, limited research exists on their struggles and coping strategies in these settings, especially outside of camps. Against this backdrop, our qualitative study aimed to gain a deeper understanding of refugee experiences in Durban, South Africa. We conducted semistructured individual interviews with 18 adult refugees from Zimbabwe and the Democratic Republic of Congo at a community-based support center in Durban. Participants described their problems, effects on mental health, and coping abilities. Interviews were recorded and analyzed for themes. Major problems were reported with work, xenophobia/racism, mental health, physical safety, housing, healthcare, and quality of life. Participants discussed feelings of worry, fear, emotional pain, anger, powerlessness, hopelessness, worthlessness, and passive suicidal ideation. Coping mechanisms consisted of friendships, church, praying, work, physical activities, family, learning the local language, and avoidance of thoughts. Many interviewees expressed a strong desire to either return to their homeland or move elsewhere. Refugees in South Africa face considerable hardships including xenophobia, physical abuse, and work/legal obstructions. More research is needed in LMICs to identify the challenges, psychological effects, and coping in such populations so that appropriate and accessible mental health services can be created for those who require them.

    2016-01-01

    Spirituality and religion have been found to have a positive impact on adults with cancer, but these concepts have not been well examined in adolescents and young adults (AYA) with cancer. AYA often question and struggle with their religious and spiritual beliefs, so it is not clear if spirituality and religion have the same positive impact on this age group. The purpose of this review of literature was to examine the research that has been conducted in spirituality in AYA with cancer. The review covered the years from 1980 to present. The terms cancer, adolescents, and young adults as well as the phrases spirit* and relig* were used to capture the different variations of words. Nine articles were found that explored spirituality and religiosity in AYA with cancer. This review highlighted the need for clarifying the terms used in describing the concept. This lack of continuity in terms makes it difficult to compare the studies. The methods used to measure spirituality are varied. Pediatric oncology nurses need to be sensitive to the spiritual needs of their patients. This can be accomplished by keeping an open line of communication and ensuring uninterrupted time to pray or read scriptures. Because of the variety of ways to express spirituality, the important first step is to ask what spirituality means to them. © 2015 by Association of Pediatric Hematology/Oncology Nurses.

    Despite the progress of the last 15 years in combating family violence, some individuals, community agencies and institutions still support a man's "right" to control, and they often disregard the physical violence he uses. Because threats and assault are in fact against the law, a man who physically or sexually assaults his wife or girlfriend couldn't keep doing it without this support from the very people who are supposed to enforce the law and help the victims of crime-namely, police, prosecutors, judges, clergy, psychologists, social workers and doctors. Some let him get away with it, look the other way, or--unsure of what to do to stop it--do nothing at all. Thus, they reinforce his "right" to use force, even if they never say, "Go ahead, hit her." The police officer who walks a man around the block or fails to show up when called, the clergyman who advises a woman to go home and pray, the doctor who gently patches her injuries but avoids asking who inflicted them, all cooperate with the abusive man in several ways. He comes to understand that no one will stop him from doing what he does. He learns that there are no consequences to his actions--even his violent actions. He can beat up "his woman" if he wants to and get away with it.

    Combat wound healing and resolution are highly affected by the resident microbial flora. We therefore sought to achieve comprehensive detection of microbial populations in wounds using novel genomic technologies and bioinformatics analyses. We employed a microarray capable of detecting all sequenced pathogens for interrogation of 124 wound samples from extremity injuries in combat-injured U.S. service members. A subset of samples was also processed via next-generation sequencing and metagenomic analysis. Array analysis detected microbial targets in 51% of all wound samples, with Acinetobacter baumannii being the most frequently detected species. Multiple Pseudomonas species were also detected in tissue biopsy specimens. Detection of the Acinetobacter plasmid pRAY correlated significantly with wound failure, while detection of enteric-associated bacteria was associated significantly with successful healing. Whole-genome sequencing revealed broad microbial biodiversity between samples. The total wound bioburden did not associate significantly with wound outcome, although temporal shifts were observed over the course of treatment. Given that standard microbiological methods do not detect the full range of microbes in each wound, these data emphasize the importance of supplementation with molecular techniques for thorough characterization of wound-associated microbes. Future application of genomic protocols for assessing microbial content could allow application of specialized care through early and rapid identification and management of critical patterns in wound bioburden.

    This study aims to investigate the effect of management regime on canopy arthropod community of the olive tree (Olea europaea L.). Field studies were performed in two successive years, 2002 and 2003, in two olive groves, one under organic farming and the other under integrated protection. The integrated protection grove was sprayed once a year in June, with dimethoate, to control the anthophagous generation of the olive moth, Prays oleae (Bern.). From April to November of each year, the canopy arthropods were sampled weekly. PRC method was used to analyse the effect of management regime at the community level and results showed that taxa responded differently to insecticide application suggesting that the organic grove was a more suitable habitat for the arthropods than the integrated protection grove. Abundance of arthropods peaked in May and June for both years but, after spraying with dimethoate, decreased significantly in integrated protection grove, recovering very slowly thereafter. Psocoptera, Miridae, Formicidae and Coccinellidae were the most sensitive taxa to insecticide application. Their decreasing in abundance was more evident in the second year of the trial. On the other hand chrysopids showed some tolerance to insecticide applications. These results suggest that the timing of spray is of utmost importance in reducing the side effects of spraying on beneficial arthropods. Moreover, differences in population susceptibility as well as in life cycle patterns must be considered.

    Aposematism involves predators learning conspicuous signals of defended prey. However, prey species utilize a wide range of chemical (or physical) defenses, which are not likely to be equally aversive to all predators. Aposematism may therefore only be effective against a physiologically sensitive subset of potential predators, and this can only be identified through behavioral testing. We studied the emerging model organism Tectocoris diophthalmus (Heteroptera: Scutelleridae), an aposematically colored but weakly defended shieldback stinkbug, to test the efficacy of its defenses against a suite of predator types. We predicted the bugs' defenses would be ineffectual against both experienced and naïve birds but aversive to predaceous insects. Surprisingly, the opposite pattern was found. Both habituated wild passerines and naïve chickens avoided the bugs, the chickens after only one or two encounters. To avian predators, T. diophthalmus is aposematic. However, praying mantids showed no repellency, aversion, or toxicity associated with adult or juvenile bugs after multiple trials. Comparison with prior studies on mantids using bugs with chemically similar but more concentrated defenses underscores the importance of dose in addition to chemical identity in the efficacy of chemical defenses. Our results also emphasize the importance of behavioral testing with multiple ecologically relevant predators to understand selective pressures shaping aposematic signals and chemical defenses.

    The Intra-Uterine Device (IUD) is an effective method of contraception, but in Bangladesh is associated with high levels of discontinuation within the first year. This study involved data collection from a retrospective cohort of women who had an IUD inserted 12 months earlier. In the cohort, 330 women were interviewed to identify factors associated with discontinuation. Later, 20 women, of the 103 who reported discontinuing because of excessive menstrual bleeding, were interviewed again and in depth about these issues. Of 330 women who had an IUD inserted, 47.3% had discontinued use one year post-insertion. In univariate and multivariate analyses, IUD discontinuation was strongly associated with side-effects (heavier periods; abdominal pain) and spousal factors (not discussing IUD with husband pre-insertion), but not with service delivery factors. In-depth interviews with women who reported excessive blood loss as the main reason for discontinuation found a doubling of both menstrual days and blood loss after IUD insertion. In Bangladesh, women cannot pray, have sexual intercourse, perform household tasks or participate in community activities during menstruation. Thus, women with menstrual side-effects faced serious physical, social and psychological challenges that made continuation difficult. Among those who discontinued, spouses were generally unsupportive and sometimes abusive, particularly when not involved in the decision to use the IUD.

    This is a 1-year prospective study to investigate the prognostic value of coping strategies such as catastrophising for persistent pain after a whiplash injury. A consecutive series of 96 patients who were seen in the emergency room in the acute phase after the injury were followed prospectively for 1 year. Age, gender and whether or not pain in the neck preceded the accident was recorded. Cases involving fractures or dislocations of the cervical spine, head trauma or pre-existing neurological disorders were not included. The mean interval between the accident and the initial examination was 3+/-2(S.D.) days. Coping was measured using the Coping Strategies Questionnaire (CSQ). The outcome parameter was self-reported neck pain at 1 year after the motor vehicle accident. At 1 year, 34% of the patients had neck pain. Women developed chronic neck pain more often than men (71% versus 29%); they also had significantly higher coping activity, such as diverting attention, praying or hoping (p<0.05), catastrophising and increasing behavioural activities (p<0.0001). Women reported pain in the neck or shoulder more often before the accident and this was the only statistically significant predictor of chronic symptoms when analysed by logistic regression (odds ratio 4.5). To conclude, we found no evidence that the different coping patterns during the early phase after a whiplash injury influenced the prognosis.

    Since the terrorist attacks of September 11, 2001, little is known about how Muslims, as a minority group, cope with the challenges associated with engaging their religious practices in a predominantly non-Islamic context. This study aims to investigate how international Muslim science students dealt with the difficulties they faced in their religious practices in a foreign context, and specifically in their research laboratories and in the wider Taiwanese society with its pluralistic spiritual beliefs. Fourteen male Muslim graduate students from Indonesia were recruited to participate in a qualitative interview. In terms of conventional content analysis, their adjustment issues were related to their religious issues, including gender roles both inside and outside of the laboratory, inconvenient practices relating to prayer needs, and eating halal foods and having to face social discrimination off campus. Two types of major adaptation strategies were identified for dealing with such struggles, including religious coping through their Islamic beliefs and bicultural connections. Their major concerns about religious practices (e.g., praying 5 times per day) were resolved by communicating their needs directly with their laboratory classmates and advisors; however, they navigated the gender boundaries in the laboratory both subtly and inwardly through their Islamic beliefs. The practical implications regarding counseling and education are discussed both in a local and a global context. (c) 2015 APA, all rights reserved).

    Context: Parents' despair and feelings of grief, as well as communication and coordination that is less than adequate between the parents and the palliative team, can affect the provision of a qualified palliative care plan for children and their families. Aims: This study aims to explore the parents' experience in caring for children with cancer under palliative care condition. Setting and Design: The research applied descriptive qualitative phenomenology design. Subjects and Methods: The study was conducted at Jakarta, Bogor, and Bekasi. Parents who caring their child with cancer under palliative care were in-depth interviewed with open-ended question. Data were then analyzed using the Colaizzi method. Results: This study resulted in two themes, still hoping for a miracle of God and always being surrendered while under palliative care. Parents still hope for a miracle of God to keep having their children during palliative care. The forms of surrendering exhibited by the parents in this study are believing in God, praying to God, saying thanks to God, relying on God, and preparing to face the deaths of their children. Conclusion: This study shows that during palliative care, parents cannot be separated from their relationship with God. Therefore, nurses are vital to the continuous assessment of parents' spiritual needs and to the facilitation of need fulfillment involving family and religious figures. PMID:29736112

    We examine how understandings of ordinary and extraordinary communication develop. Three- to 10-year-old children and adults (N = 183) were given scenarios in which a protagonist wanted help from a human (their parent) or from God. Scenarios varied in whether protagonists expressed their desires aloud (by asking) or silently (by hoping), whether (for human scenarios) parents were nearby or far away, and whether (for God scenarios) protagonists expressed desires through ordinary means (asking or hoping) or more extraordinary means (praying). Following each scenario, participants were asked whether the recipient (either the parent or God) was aware of the protagonist's desire. Children as young as 3 to 4 years old understood that both loudness and distance limit the effectiveness of human communication, reporting that humans would most likely be aware of desires when they were expressed both aloud and nearby. As well, by this age children reported that God would more often be aware of desires than would humans, but children of all ages often reported that God (like humans) would be more aware of desires expressed aloud (rather than silently). These concepts of ordinary and extraordinary communication continued to be refined through middle childhood. Children's performance on standard theory-of-mind tasks and participants' religious background predicted whether they attributed awareness to God.

    To determine the prevalence of religious practices and beliefs of depressed elderly Australian inpatients and their relationship to physical, social, and cognitive variables known to influence the prognosis of depression in the elderly. To compare the results obtained with those from similar North American studies. Inpatients with a DSM-IV diagnosis of major depression were interviewed on admission to the psychogeriatric unit of a Melbourne geriatric centre. Information collected included patient demographics, intrinsic and extrinsic religiosity, cognitive function, severity of depression, number of chronic illnesses, physical function, and numbers and quality of social support. Pearson correlation and multivariate analysis using a standard regression model were used to examine relationships between the religious and other variables. Of the 86 patients who completed the assessment, 25% attended church regularly and 37% prayed, meditated, or read the Bible, at least once a day. Just over half rarely or never engaged in such behaviours. Three out of every eight patients were 'intrinsically' religious. Religious patients expressed higher levels of social support and physically disabled patients were more likely to be religious. Depressed elderly Australian inpatients are less religious than their North American counterparts. Nevertheless, religion remains important for a large minority of such individuals. Clinicians need to be aware that such individuals may turn to religion when depressed, especially to cope with the presence of physical disability.

    The sacred space becomes an important part of the spatial layout of Javanese society, as well as in most houses of the archipelago. This space is related to religious activities, highly respected and usually located in the main place. Kudus Kulon community is a part of Javanese culture in the northern coastal area of Java. Known as a devout Muslim society, sacred space in Kudus Kulon community house becomes an important thing to understand the culture of living in society. The research was conducted by looking at the religious activities of the community and how the space of activity is realized. The research was conducted by qualitative research method. In the Kudus Kulon community, sacred spaces are available in the house itself, in the community grup of houses, and around Kudus Kulon area. In every house, the sacred space can be found in Gedongan and extends to Dalem. In the community group of houses, the sacred space can be found in the neighbourhood praying area, while In Kudus Kulon area, it can be found in Mosque complex and Tower tomb. Physically sacred space is realized by raising the floor height of the space around it. In architectural view, the sacred space is seen on the elevation of the roof or roof angle. Spatially the sacred space occupies a central position and visually represented by a vertical orientation.

    According to Poloma and Pendleton's (J Psychol Theol 19:71-83, 1991) prayer model, there are four prayer types (colloquial, meditative, petitionary, and ritual), all of which have varying associations with mental health. However, few studies have examined what mechanisms explain these associations. The literature demonstrates that disclosing distressing information can improve mental health. Thus, the current study examined self-disclosure as a mediating variable between Poloma and Pendleton's (J Psychol Theol 19:71-83, 1991) prayer types and mental health. It was hypothesized that self-disclosure would mediate the association between prayer types involving meaningful communication with God (colloquial and meditative prayer types) and mental health and would not mediate associations between petitionary and ritual prayer types and mental health. This cross-sectional, online study analyzed data from praying Christian adults (N = 296) to test the hypotheses. As predicted, self-disclosure mediated the positive associations between colloquial and meditative prayer types and mental health. Self-disclosure was not associated with petitionary or ritual prayer and therefore did not mediate the relationships of these prayer types with mental health, as expected. Petitionary prayer had a negative relationship to mental health, while ritual prayer had a positive relationship to mental health. The results indicate that self-disclosure is an important mediator to consider when investigating the associations between private prayer and mental health.

    Background Neuropeptide ligands have to fit exactly into their respective receptors and thus the evolution of the coding regions of their genes is constrained and may be strongly conserved. As such, they may be suitable for the reconstruction of phylogenetic relationships within higher taxa. CAPA peptides of major lineages of cockroaches (Blaberidae, Blattellidae, Blattidae, Polyphagidae, Cryptocercidae) and of the termite Mastotermes darwiniensis were chosen to test the above hypothesis. The phylogenetic relationships within various groups of the taxon Dictyoptera (praying mantids, termites and cockroaches) are still highly disputed. Results Tandem mass spectrometry of neuropeptides from perisympathetic organs was used to obtain sequence data of CAPA peptides from single specimens; the data were analysed by Maximum Parsimony and Bayesian Interference. The resulting cladograms, taking 61 species into account, show a topology which is in general agreement with recent molecular and morphological phylogenetic analyses, including the recent phylogenetic arrangement placing termites within the cockroaches. When sequence data sets from other neuropeptides, viz. adipokinetic hormones and sulfakinins, were included, the general topology of the cladogram did not change but bootstrap values increased considerably. Conclusion This study represents the first comprehensive survey of neuropeptides of insects for solely phylogenetic purposes and concludes that sequences of short neuropeptides are suitable to complement molecular biological and morphological data for the reconstruction of phylogenetic relationships.

    Summary Background Most breast cancer patients use complementary and alternative medicine (CAM), usually in parallel with their conventional treatments. This study was planned to determine the prevalence and determining factors for use of CAM by breast cancer patients undergoing chemotherapy. Patients and Methods This descriptive study was carried out between October 2010 and May 2011, and included 96 patients at the Istanbul University Institute of Oncology. The Patient Characteristics form and Complementary and Alternative Medicine Scale were used for data collection. Descriptive and non-parametric tests were performed, and logistic regression analysis was used to predict factors affecting CAM use. Results Praying was the most frequently used form of CAM, and most of the herbal supplements used by patients were harmless. Herbal use was higher among patients who had local disease (relative risk (RR) 4.48%, 95% confidence interval (CI) 1.12–17.95), and worship was more common among those who had not undergone surgery (RR 4.66%, 95% CI 1.64–13.20). Conclusion The CAM approaches used by patients were found to be safe. However, sage and flax seed usage for estrogen-and progesterone-positive patients and exercise for patients with spinal metastasis can be inappropriate approaches. It is important to question and inform patients about CAM use during treatment. PMID:24715829

    Medieval headache treatment is largely unknown. Medieval incantations against headache enumerate bodily organs to be protected. One 8th-century Latin hymn from Lake Constance using this device is addressed to St. Aid "mechprech", who has been identified as Aed Mac Bricc, Bishop of Killare, 6th century. This Irish Saint inspired unusual legends by some rather unorthodox activities: He abducted a young girl as hostage while his inheritance was withheld, but at the same time was seen surrounded by angels. He prayed for a nun who was pregnant and made the pregnancy vanish by a miracle, and he replaced the severed heads of maids, men and horses, creating a new spring as a by-product of this operation. Already at his birth his head had hit a stone, leaving a hole in the stone which collected rainwater that cured all ailments. In our own time, such "bullaun stones" are still believed to cure headache in Ireland. According to the legends collected by Plummer and Colgan, St. Aed Mac Bricc was well known for his power to cure headaches. He relieved St. Brigid's headache when she was suffering many miles away, but his most impressive cure was in convincing a headache sufferer that the patient's headache could actually be transferred own head. The headache hymn or incantation is intended to repeat Aed's unique miracle.

    Adult northern squawfish Ptychocheilus oregonensis, walleyes Stizostedion vitreum, smallmouth bass Micropterus dolomieu, and channel catfish Ictalurus punctatus were sampled from four regions of John Day Reservoir from April to August 1983–1986 to quantify their consumption of 13 species of prey fish, particularly seaward-migrating juvenile Pacific salmon and steelhead (Oncorhynchus spp.). Consumption rates were estimated from field data on stomach contents and digestion rate relations determined in previous investigations. For each predator, consumption rates varied by reservoir area, month, time of day, and predator size or age. The greatest daily consumption of salmonids by northern squawfish and channel catfish (0.7 and 0.5 prey/predator) occurred in the upper end of the reservoir below McNary Dam. Greatest daily predation by walleyes (0.2 prey/predator) and smallmouth bass (0.04) occurred in the middle and lower reservoir. Consumption rates of all predators were highest in July, concurrent with maximum temperature and abundance of juvenile salmonids. Feeding by the predators tended to peak after dawn (0600–1200 hours) and near midnight (2000–2400). Northern squawfish below McNary Dam exhibited this pattern, but fed mainly in the morning hours down-reservoir. The daily ration of total prey fish was highest for northern squawfish over 451 mm fork length (> 13.2 mg/g predator), for walleyes 201–250 mm (42.5 mg/g), for smallmouth bass 176–200 mm (30.4 mg/g), and for channel catfish 401–450 mm (17.1 mg/g). Averaged over all predator sizes and sampling months (April–August), the total daily ration (fish plus other prey) of smallmouth bass (28.7 mg/ g) was about twice that of channel catfish (12.6), northern squawfish (14.1), and walleyes (14.2). However, northern squawfish was clearly the major predator on juvenile salmonids.

    The aim of this study is to describe religious and spiritual beliefs of physicians and examine their influence on the decision to pursue medicine and daily medical practice. An anonymous survey was e-mailed to physicians at a large, multidisciplinary tertiary referral center with satellite clinics. Data were collected from January 2014 through February 2014. There were 2097 respondents (69.1 % men), and number of practicing years ranged from ≤1 to ≥30. Primary care physicians or medical specialists represented 74.1 %, 23.6 % were in surgical specialties, and 2.3 % were psychiatrists. The majority of physicians believe in God (65.2 %), and 51.2 % reported themselves as religious, 24.8 % spiritual, 12.4 % agnostic, and 11.6 % atheist. This self-designation was largely independent of specialty except for psychiatrists, who were more likely report agnosticism (P = 0.003). In total, 29.0 % reported that religious or spiritual beliefs influenced their decision to become a physician. Frequent prayer was reported by 44.7 % of physicians, but only 20.7 % reported having prayed with patients. Most physicians consider themselves religious or spiritual, but the rates of agnosticism and atheism are higher than the general population. Psychiatrists are the least religious group. Despite the influence of religion on physicians' lives and medical practice, the majority have not incorporated prayer into patient encounters.

    People with chronic kidney disease (CKD) face various problems including psychological, socioeconomic and physical effects associated with CKD and its treatment. They need to develop strategies to help them cope with CKD and life challenges. Religion and spirituality are important coping strategies, but their role in helping people cope with CKD and haemodialysis (HD) in Thailand is relatively unknown. To investigate the role of religion and spirituality in coping with CKD and its treatment in Thailand. An exploratory, qualitative approach was undertaken using semistructured individual interviews. Purposive sampling was used to recruit participants. Face-to-face, in-depth individual interviews using open questions were conducted during January and February 2012. Interviews were audio-recorded and transcribed verbatim. Data were analysed using the framework method of qualitative data analysis. Twenty people receiving HD participated: age range 23-77 years, mean 53.7 (±16.38 SD). Ten were women. Participants reported use of religious and spiritual practices to cope with CKD and its treatment, including religious and spiritual explanations for developing CKD, karmic disease, making merit, reading Dharma books, praying and chanting to save life and making a vow to Pran-Boon. Religion and spirituality provide powerful coping strategies that can help Thai people with CKD overcome the associated distress and difficulties. Religion and spirituality cannot be separated in Thai culture because Thai people are both religious and spiritual. © 2016 Nordic College of Caring Science.

    Although very little is known about African American cancer patients' pain experience, a few studies have indicated that their cancer pain experience is unique and somewhat different from that of other ethnic groups. The purpose of the study reported in this article was to explore African American cancer patients' pain experience using an online forum. This study was a qualitative online forum designed from a feminist perspective and conducted among 11 African American cancer patients who were recruited through both Internet and real settings. Nine online forum topics were used to administer the 6-month online forum, and the data were analyzed using thematic analysis. Four themes emerged through the data analysis process. First, participants viewed cancer as a challenge in life that they should fight against. Second, cancer pain was differentiated from ordinary pain because cancer was stigmatized in their culture. Third, participants viewed that African Americans, especially women, were culturally raised to be strong, and this African American cultural heritage inhibited cancer patients from expressing pain and seeking help for pain management. Finally, the findings indicated certain changes in perspectives among African American cancer patients during the disease process, which might make them tolerate pain through praying to God and reading the Bible. Based on the findings, we suggest further studies among diverse groups of African American cancer patients, with a focus on cultural attitudes toward cancer pain and influences of family on cancer pain experience.

    This research has focused on the birthing experience of first-time mothers who received the narcotic analgesic combination of Pethidine and Hydroxyzine during the first stage of labour. A qualitative research methodology was used to collect data. Unstructured interviews were held with first-time mothers to obtain accounts of their experience of childbirth. These narrations were audio-taped while the participants were still being cared for in the postnatal ward of the hospital where delivery took place. Nine interviews were conducted with first-time mothers who gave birth normally vaginally after a normal pregnancy and who received a narcotic analgesic in the first stage of labour. The transcribed interviews were analyzed using Tesch's method of descriptive analysis (in Creswell, 1994:115). Four themes with sub-themes emerged from the analysis. The participants reported on the physical experience of labour and described experiencing a lot of pain for which analgesics were given. They also described how these drugs dulled the pain but made them sleepy and unable to cooperate with the midwives. They described their emotional experiences, which included joy and happiness as well as anxiety, anger and despondence. They also reported that they were not sufficiently informed about labour and child-birth. In the last theme they described the methods they used to help them cope with labour including distracting techniques, leaning on a supportive person or praying. Guidelines to help midwives overcome these problems were developed.

    The study aimed to gather data on posttraumatic stress and depression in adolescents following the 2015 Nepal earthquake and explore the adolescents' coping strategies. In a questionnaire-based, cross-sectional study about 1 year after the earthquake, adolescents in two districts with different degrees of impact were evaluated for disaster experience, coping strategies, and symptoms of posttraumatic stress and depression measured with the Child Posttraumatic Stress Scale and the Depression Self Rating Scale. In the studied sample (N=409), the estimated prevalence of posttraumatic stress disorder (PTSD) (43.3%) and depression (38.1%) was considerable. Prevalence of PTSD was significantly higher in the more affected area (49.0% v 37.9%); however, the prevalence figures were comparable in adolescents who reported a stress. The prevalence of depression was comparable. Female gender, joint family, financial problems, displacement, injury or being trapped in the earthquake, damage to livelihood, and fear of death were significantly associated with a probable PTSD diagnosis. Various coping strategies were used: talking to others, praying, helping others, hoping for the best, and some activities were common. Drug abuse was rare. Most of the coping strategies were comparable among the clinical groups. A considerable proportion of adolescents had posttraumatic stress and depression 1 year after the earthquake. There is a need for clinical interventions and follow-up studies regarding the outcome. Disaster Med Public Health Preparedness. 2018;page 1 of 7.

    The purpose of this study was to assess patient-reported symptoms and self-care methods used during cancer treatments, using checklists. A descriptive study was performed at the cancer institute of a national medical center in Manila on 100 patients undergoing combined radiotherapy and chemotherapy, n = 37, or chemotherapy alone, n = 63. Instruments used were (a) 25-item patient-reported Therapy-Related Symptoms Checklist (TRSC), (b) Self-care Methods (with the 25 TRSC items) tool, (c) Karnofsky Scale, (d) Demographic form, and (e) Health form. The TRSC (Philippine version) Cronbach alpha = .83. The TRSC scores inversely, significantly correlated with nurse-rated Karnofsky measure of functional status (r = -0.45; P < .001)-all evidences of internal consistency reliability, construct, and concurrent validity; similar findings were found in Midwestern United States and 2 other Asian settings. Compared with those receiving chemotherapy alone, patients who had combined radiotherapy and chemotherapy reported more symptoms with greater severity on several TRSC subscales. Self-care methods most used were in 2 categories: (a) diet/nutrition/lifestyle change (eg, modify food/eating habits; eat vegetables and fruits (papaya); use nutritional supplements; have naps, rest, sleep) to manage eating, oropharynx, nausea, and fatigue subscale symptoms; and (b) mind/body control (eg, prayer, praying the rosary, music) to relieve fatigue subscale, other symptoms. The TRSC (Philippine version) and Self-care Methods assess patient-reported symptoms and patients' self-care use. Oncology symptom management is enhanced by a valid clinical assessment tool.

    To explore nurse comfort with patient-initiated prayer request scenarios. Spiritual care is fundamental to patient care evidenced by Joint Commission requirement of a spiritual assessment on a patient's hospital admission. Prayer is an assessment component. Patients may seek solace and support by requesting prayer from the bedside nurse, the nurse may lack confidence in responding. Absent in the literature are reports specific to nurses' comfort when patients initiate prayer requests. Cross-sectional mixed methods study. Data were collected in early 2014 from 134 nurses in the USA via an online survey using QuestionPro. The qualitative results reported here were collated by scenario and analysed using thematic analysis. The scenario responses revealed patterns of ease and dis-ease in response to patient requests for prayer. The pattern of ease of prayer with patients revealed three themes: open to voice of calm or silence; physical or spiritual; can I call the chaplain. For these nurses, prayer is a natural component of nursing care, as the majority of responses to all scenarios demonstrated an overwhelming ease in response and capacity to pray with patients on request. The pattern of dis-ease of prayer with patients distinguished two themes: cautious hesitancy and whose God. These nurses experienced dis-ease with the patient's request no matter the situation. Educators and administrators must nurture opportunities for students and nurses to learn about and engage in the reflective preparation needed to respond to patient prayer requests. © 2016 John Wiley & Sons Ltd.

    Muslims throughout the world perform salat (prayer) five times a day; salat involves a person reciting the Holy Qur'an while being in several positions. There are several steps that should be carried out before prayer, including wudhu (ablution) and covering one's awrah (body). To identify educational needs for stroke patients and their caregivers in Malaysia. Another purpose is to report on the needs identified by stroke patients and their families related to salat. Descriptive qualitative study. Phase 1 involved semi-structured interviews with stroke patients (n = 5), family caregivers (n = 5) and health professionals (n = 12) in Kelantan Malaysia. Phase 2 involved presenting the findings from Phase 1 to the health professionals with the aim of establishing priorities and processes to develop education strategies for stroke patients and their families. Preparing for and performing salat was challenging for both patient and family carers to do following a stroke. Themes identified were prayer and the meaning of the stroke events for participants, difficulties praying post-stroke, prayer as part of rehabilitation therapy. Providing culturally safe care should include how nurses assess and support patients and their caregivers post stroke to meet their prayer needs. Nurses have a role in discussing with stroke patients and their families how in addition to its spiritual and customary benefits, prayer and for Muslims reciting the Holy Qur'an can have cognitive and rehabilitation benefits, as well as being a source of psychological support for stroke patients.

    As a public building, a mosque (or any prayer area for Muslims in public buildings) should remove all barriers that may confront persons with disabilities and hinder them from performing their religious rituals. A mosque is regularly used at least five times a day for praying, and for weekly events such as Jumu'ah (Friday prayers). Therefore. a mosque should be accessible for all. But in fact, persons with disabilities still find difficulties in accessing mosques. For example, the calling to prayer and Friday sermon (Khutba) through loudspeakers, is a problem for persons with hearing loss. Persons with physical disabilities, especially users of wheelchairs, walkers or crutches, have difficulties in several areas in the mosque, including the entrance, place of ablution, the lavatories and the area for removing shoes at the entrance to the prayer hall. People are not allowed to enter the place of ablution or prayer hall wearing shoes, people are also not allowed to enter with their personal mobility devices. This is so that dirt from outside does not get carried into the mosque. In order to understand the accessibility requirements for persons with disabilities in a mosque, we have to know the essential parts in the construction of the mosque and the mobility pattern that usually occurs in a mosque. In this paper, an accessibility checklist which has been developed on the basis of an analysis of accessibility requirements in mosques is presented.

    Significant changes in the economic, familial and social support aspects in India have occurred in recent times, making it an interesting naturalistic setting to observe the effects of a dynamic socioeconomic environment on behavioral and emotional disorders in adolescents. This systematic review attempts to synthesize and evaluate the available evidence on mental health disorders and interventions in adolescents in India in last 10 years as well as identify conceptual trends and methodological lacunae in these studies. A systematic search of electronic databases was performed in March 2014 and 27 school and community based studies evaluating behavioral problems, psychiatric morbidity, stress, suicide-related behaviors, depression, anxiety, aggression, self concept in adolescents in India were reviewed. There is a wide variation in the reported prevalence of psychiatric morbidity and behavioral problems in Indian adolescents. Some of the risk and protective factors are similar to those identified by other International studies in this age group. These include female gender, academic difficulties, parental fights, strained familial relationships, school absenteeism, school dropout and other school related factors. However, there are certain variables that appear to be context specific and need further investigation. These are mother's working status, studying in Government institutions or belonging to a nuclear family as risk factors and praying as a coping skill, parental involvement as a protective factor for psychiatric disorders. The suspected upward trend in the psychiatric morbidity in this age group needs more studies to be established. Copyright © 2014 Elsevier B.V. All rights reserved.

    It is well known that human behavior and individual psychological traits are moderately to substantially heritable. Over the past decade, an increasing number of studies have explored the genetic and environmental influence on religiousness. These studies originate predominantly from countries generally considered more religious than the very secular northern European countries. Comparisons of the results are complicated by diverse definitions of religiousness, but several studies indicate that the influence of the family environment is most predominant in early life, whereas genetic influences increase with age. We performed a population-based twin study of religiousness in a secular society using data from a Web-based survey sent to 6,707 Danish twins born 1970-1989, who were identified in the Danish Twin Registry. We applied Fishman's three conceptual dimensions of religiousness: cognition, practice, and importance. In all polygenic models and biometric analyses, we controlled for gender and age. The study sample comprised 2,237 same sex twins, a response rate of 45%. We found high correlations within both monozygotic and dizygotic twin pairs in most items of religiousness, indicating a large influence from shared environmental factors. Personal religiousness such as praying to God, believing in God, and finding strength and comfort in religion were more influenced by genetic factors than were social forms of religiousness such as church attendance. We found a small tendency for increasing genetic influence with increasing age for some religious items, but not for all.

    The Palmetto Gulch area is affected by low pH and metal-bearing drainage from abandoned mines, and perhaps, from natural weathering around vein zones. To investigate these anthropogenic and potential natural sources of acidity and metals, we mapped the geology, veins, and hydrothermally altered areas; conducted mine dump leachate studies; and collected reconnaissance water quality data. Several small abandoned mines are present in the Palmetto Gulch area that produced small amounts of relatively high-grade silver ore from fault-controlled polymetallic vein deposits. These veins are hosted in lavas, breccias, and related volcaniclastic sediments that ponded within the 28 Ma San Juan-Uncompahgre caldera complex. These rock units generally have conformable contacts and have shallow dips to the northwest. Lava flows of pyroxene andesite, which host the Roy-Pray mine, are massive near their base and typically grade upward into tightly jointed rock with 2-15 cm joint spacing. In general, most hydrothermally altered rock within the Palmetto Gulch area is restricted to envelopes surrounding the mineralized veins and faults. Composite zones of vein-related alteration vary from about 50 to 80 m wide along the high ridgelines and narrow to less than 10 to 15 m beneath an elevation of about 5,462 m. Where unaffected by surficial oxidation, these altered zones contain as much as 7 to 10 volume percent finely-disseminated pyrite. The majority of rocks in the area were affected by regional and vein-related propylitic alteration. These greenish-colored rocks have alteration products consisting of chlorite, illite, and calcite; and feldspars are typically weakly altered. Most of these rocks have detectable amounts of calcite, while as much as 11 percent by weight was detected in samples collected during this study. The Palmetto Gulch area is affected by low pH and metal-bearing drainage from abandoned mines, and perhaps, from natural weathering around vein zones. To investigate

    Religion exerts a significant effect on the lives of many individuals including people with mental illness. As evidences keep accumulating, role of religion in mental illness is gaining importance. The study was designed to study the effects of religiosity on religious delusions, its presentation, acute course and outcome in schizophrenia. The study was a naturalistic observational study. Subjects with schizophrenia were grouped into those with religious (RG) and with non-religious delusions (NG). Their premorbid religiosity was assessed with Brief Multi-dimensional measurement of Religiosity/spirituality (BMMRS) and were rated on Scale for Assessment of Positive Symptoms (SAPS), Brown's Assessment of Belief Scale (BABS) and Positive and Negative Symptom Scale (PANSS) at baseline and 4 weeks. Scores on private religious practices, baseline scores of SAPS, BABS & PANSS and duration of untreated psychosis (DUP) were significantly higher for RG in comparison to NG. On component analysis, higher scores were seen on private praying, watching religious programs on TV, reading religious books and prayers at meals. But no significant correlation was found between the private religious practices and the baseline scores of (DUP), SAPS, BABS, PANSS and outcome measure. Also no significant difference was noted in measures of improvement between groups. Private religious practices are more prominent in patients of schizophrenia with religious delusions and this group of patient seems to present with a more severe illness, and a longer duration of untreated psychosis in comparison to those with non-religious delusions.

    An analytic cognitive style denotes a propensity to set aside highly salient intuitions when engaging in problem solving. We assess the hypothesis that an analytic cognitive style is associated with a history of questioning, altering, and rejecting (i.e., unbelieving) supernatural claims, both religious and paranormal. In two studies, we examined associations of God beliefs, religious engagement (attendance at religious services, praying, etc.), conventional religious beliefs (heaven, miracles, etc.) and paranormal beliefs (extrasensory perception, levitation, etc.) with performance measures of cognitive ability and analytic cognitive style. An analytic cognitive style negatively predicted both religious and paranormal beliefs when controlling for cognitive ability as well as religious engagement, sex, age, political ideology, and education. Participants more willing to engage in analytic reasoning were less likely to endorse supernatural beliefs. Further, an association between analytic cognitive style and religious engagement was mediated by religious beliefs, suggesting that an analytic cognitive style negatively affects religious engagement via lower acceptance of conventional religious beliefs. Results for types of God belief indicate that the association between an analytic cognitive style and God beliefs is more nuanced than mere acceptance and rejection, but also includes adopting less conventional God beliefs, such as Pantheism or Deism. Our data are consistent with the idea that two people who share the same cognitive ability, education, political ideology, sex, age and level of religious engagement can acquire very different sets of beliefs about the world if they differ in their propensity to think analytically.

    Parents of seriously ill children require attention to their spiritual needs, especially during end-of-life care. The objective of this study was to characterize parental attitudes regarding physician inquiry into their belief system. Materials and Main Results: A total of 162 surveys from parents of children hospitalized for >48 hours in pediatric intensive care unit in a tertiary academic medical center were analyzed. Forty-nine percent of all respondents and 62% of those who identified themselves as moderate to very spiritual or religious stated that their beliefs influenced the decisions they made about their child's medical care. Although 34% of all respondents would like their physician to ask about their spiritual or religious beliefs, 48% would desire such enquiry if their child was seriously ill. Those who identified themselves as moderate to very spiritual or religious were most likely to welcome the discussion ( P < .001). Two-thirds of the respondents would feel comforted to know that their child's physician prayed for their child. One-third of all respondents would feel very comfortable discussing their beliefs with a physician, whereas 62% would feel very comfortable having such discussions with a chaplain. The study findings suggest parental ambivalence when it comes to discussing their spiritual or religious beliefs with their child's physicians. Given that improved understanding of parental spiritual and religious beliefs may be important in the decision-making process, incorporation of the expertise of professional spiritual care providers may provide the optimal context for enhanced parent-physician collaboration in the care of the critically ill child.

    Complementary and alternative medicine (CAM) includes a wide range of practices and products that are generally outside the use of conventional medicine as practiced in Western cultures. Use of CAM in persons with epilepsy is high, even compared to individuals with other chronic health conditions. In this study, we surveyed caregivers of children admitted to a regional epilepsy monitoring unit (EMU) in the southeast United States to assess CAM use among patients (N=225). Thirteen percent of respondents indicated current use of CAM by their child, 16% reported past use, and 43% reported interest in future use, most commonly in marijuana as a potential treatment (23%). Over 25% of respondents expressed interest in CAM use related to side effects of anti-epileptic medications. Regarding prayer as a form of CAM, a large majority of respondents in this sample identified as Christian and actively prayed for their child's illness, revealing a high prevalence of spiritual practices in this population. Eighty-one percent of respondents reported that they had not discussed CAM use with their doctor. Discussing CAM use with a health care provider was significantly related to past CAM use (p<.02), but not current use or willingness to try CAM in the future (p>.05). These results have important implications for future practice and support increased communication and patient education, as many anti-epileptic medications interact with certain herbs and supplements, posing a potential health risk and treatment barrier in this population.

  7. Chemical constraints of groundwater management in the Yucatan peninsula, Mexico

    1981-05-01

    Two critical objectives of water management in the Yucatan are: (1) to develop regional groundwater supplies for an expanding population and tourism based on the Mayan archeological sites and excellent beaches; and (2) to control groundwater pollution in a chemically sensitive system made vulnerable by geologic conditions. The Yucatan peninsula is a coastal plain underlain by permeable limestone and has an annual rainfall of more than 1000 mm. Such a setting should provide abundant supplies of water; however, factors of climate and hydrogeology have combined to form a hydrologic system with chemical boundaries that decrease the amount of available fresh water. Management of water resources has long had a major influence on the cultural and economic development of the Yucatan. The Mayan culture of the northern Yucatan developed by extensive use of groundwater. The religion was water-oriented and the Mayan priests prayed to Chac, the water god, for assistance in water management primarily to decrease the severity of droughts. The Spaniards arrived in 1517 and augmented the supplies by digging wells, which remained the common practice for more than 300 years. Many wells now have been abandoned because of serious problems of pollution resulting from the use of a sewage disposal well adjacent to each supply well. The modern phase of water management began in 1959 when the Secretaría de Recursos Hidráulicos (S.R.H.) was charged with the responsibility for both scientific investigations and development programmes for water-supply and sewage-disposal systems for cities, villages and islands.

  8. English use among older bilingual immigrants in linguistically concentrated neighborhoods: Social proficiency and internal speech as intracultural variation

    This research focuses on patterns of English proficiency and use-of-English among older immigrants living in linguistically concentrated, ethnic neighborhoods. A sample (n=60) of older Puerto Ricans, who moved from the island to the mainland in their twenties, were divided into English proficiency groups (fluent, high intermediate, low intermediate) via the Adult Language Assessment Scales. Participants then provided self-ratings of their English proficiency (understanding, speaking, reading, and writing), their use of English in social domains (language spoken with own-family, in-laws, spouse, children, neighbors, and workmates), and their use of English in private psychological domains (language of talking to oneself, counting, writing notes to oneself, thinking, dreaming, praying, and expressing feelings). Finally, all participants completed the Puerto Rican Bicultural Scale. Results show a cohort of immigrant elders whose first language is protected by their ethnic neighborhoods but whose domestic and private lives are increasingly permeated by English. In particular, children emerge as powerful forces of language socialization in English for their parents. Further, there are important individual differences by level of proficiency, with a lowest proficiency group that is less acculturated, lower in socioeconomic status, and even more linguistically isolated than groups with higher proficiency. In essence, level of second language proficiency is a potent source of intracultural variation. Methodologically, the paper makes the important point that self-rated patterns of language use are consistent with scores on formal measures of proficiency. The paper also provides empirical verification of the logic of dividing language use into external, social speech and internal, psychological speech. PMID:19184621

  10. Is Ground Cover Vegetation an Effective Biological Control Enhancement Strategy against Olive Pests?

    2015-01-01

    Ground cover vegetation is often added or allowed to generate to promote conservation biological control, especially in perennial crops. Nevertheless, there is inconsistent evidence of its effectiveness, with studies reporting positive, nil or negative effects on pest control. This might arise from differences between studies at the local scale (e.g. orchard management and land use history), the landscape context (e.g. presence of patches of natural or semi-natural vegetation near the focal orchard), or regional factors, particularly climate in the year of the study. Here we present the findings from a long-term regional monitoring program conducted on four pest species (Bactrocera oleae, Prays oleae, Euphyllura olivina, Saissetia oleae) in 2,528 olive groves in Andalusia (Spain) from 2006 to 2012. Generalized linear mixed effect models were used to analyze the effect of ground cover on different response variables related to pest abundance, while accounting for variability at the local, landscape and regional scales. There were small and inconsistent effects of ground cover on the abundance of pests whilst local, landscape and regional variability explained a large proportion of the variability in pest response variables. This highlights the importance of local and landscape-related variables in biological control and the potential effects that might emerge from their interaction with practices, such as groundcover vegetation, implemented to promote natural enemy activity. The study points to perennial vegetation close to the focal crop as a promising alternative strategy for conservation biological control that should receive more attention. PMID:25646778

    To evaluate the moderating effects of various coping strategies on the association between stressors and the prevalence of major depression in the general population. Subjects from the Alberta buy-in component of the 1994-1995 National Population Health Survey (NPHS) were included in the analysis (n = 1039). Each subject was asked 8 questions about coping strategies that dealt with unexpected stress from family problems and personal crises. Major depression was measured using the World Health Organization's (WHO) Composite International Diagnostic Interview-Short Form (CIDI-SF) for major depression. The impacts of coping strategies in relation to psychological stressors on the prevalence of major depression were determined by examining interactions between coping and life stress on major depression using logistic regression modelling. No robust impact of coping strategies in relation to various categories of stress evaluated in the NPHS was observed. There was evidence that the use of "pray and seek religious help" and "talks to others about the situations" as coping strategies by women moderated the risk of major depression in the presence of financial stress and relationship stress (with a partner). Using emotional expression as a coping strategy by women might decrease the risk of major depression in the presence of 1 or more recent life events, personal stress, relationship stress (with a partner), and environmental stress. Different coping strategies may have a differential impact on the prevalence of major depression in specific circumstances. These findings may be important both to prevent and to treat depressive disorders.

    Ninety percent of American adults believe in God and 82% pray weekly. A majority wants their physicians to address spirituality during their health care visit. However, clinicians incorporate spiritual discussion in less than 20% of visits. Our objectives were to measure clinician beliefs and identify perceived barriers to integrating spirituality into patient care in a statewide, primary care, managed care group. Practitioners completed a 30-item survey including demographics and religious involvement (DUREL), spirituality in patient care (SPC), and barriers (BAR). We analyzed data using frequencies, means, standard deviations, and ANOVA. Clinicians had a range of religious denominations (67% Christian, 14% Jewish, 11% Muslim, Hindu or Buddhist, 8% agnostic), were 57% female and 24% had training in spirituality. Sixty-six percent reported experiencing the divine. Ninety-five percent felt that a patient's spiritual outlook was important to handling health difficulties and 68% percent agreed that addressing spirituality was part of the physician's role. Ninety-five percent of our managed care group noted 'lack of time' as an important barrier, 'lack of training' was indicated by 69%, and 21% cited 'fear of response from administration'. Managed care practitioners in a time constrained setting were spiritual themselves and believed this to be important to patients. Respondents indicated barriers of time and training to implementing these beliefs. Comparing responses from our group to those in other published surveys on clinician spirituality, we find similar concerns. Clinician education may overcome these barriers and improve ability to more fully meet their patients' expressed needs regarding spirituality and beliefs.

    Low back pain (LBP) may challenge an individual's self-confidence to perform usual daily activities such as Islamic daily prayer. Existing self-efficacy scales may not be appropriate to assess individual's self-confidence to perform Islamic prayers. This study aimed to develop a scale to assess self-confidence to prepare and perform Islamic prayer in the presence of LBP, the Islamic Prayer-based Self-efficacy Scale (IpbSeS), and to determine its consistency. The IpbSeS consists of three parts: pre-prayer preparation, getting to and from the mosque, and positions and movements during prayer. On a scale of 0 to 6, 0 indicates 'not at all confident' and 6 'fully confident'. Sixty individuals with LBP gave their responses on two different visits. Pain intensity was assessed by the Visual Analogue Scale (VAS), and the pain intensity changes were assessed using a seven-point global patient rating scale. Descriptive statistics, Pearson's correlation coefficient, Wilcoxon test and t-test were used in the analysis (alpha set at 0.05). VAS scores did not differ significantly between visits. No association was found between VAS and age (r = 0.039, p = 0.77) and between VAS and body mass index (BMI; r = 0.06, p = 0. 67). All 28 questions have consistent responses on two visits (0.75 ≤ r ≤ 0.99, p < 0.001 for all) indicating a very high reliability. IpbSeS appears to be a reliable instrument to assess the self-confidence of Muslims in the presence of LBP to pray. Copyright © 2011 John Wiley & Sons, Ltd.

  14. Ritual's role in profound change.

    PubMed

    1995-03-01

    In today's healthcare environment, characterized by downsizing, restructuring, mergers, and acquisitions, organizational cultures and employees are experiencing rapid--and often tense--changes. Ritual can facilitate change by acknowledging it and allowing the grieving process to take its course. The success of an organizational culture change can depend on whether the organization and its members have been given an opportunity to grieve. Until they grieve their losses, people cannot embrace the new. Organizational leaders who have survived downsizing must come to grips with their own survivor status first and then lead others in the organization through the current painful but irrevocable shift in their relationship to the organization. The use of ritual helps organizational survivors see the connection between the grieving process and their survivor symptoms of denial, anger, depression, guilt, fear, insecurity, anxiety, and uncertainty. A good ritual should allow those present to rise above barriers that separate, worries that overburden, and blindness that limits and to gather as one with God. As a rule, a good ritual is participative and recognizes the audience's diversity. The ritual should not just address those present but invite them to act, pray, or sing. Ritual is an important way to provide a structure that allows people to express their emotions. For leaders, it can be a visible way to acknowledge grief and show support for organizational members. For ritual to have any meaning, key leaders need to be present and perhaps have a role in the creation and enactment of the ritual.

    Supported in the Hippocratic aphorism primum non nocere, the bioethical principle of non-maleficence pray that the medical act cause the least damage or injury to the health of the patient, leaving it to the doctor to assess the risks of a particular therapy through knowledge of possible adverse events of drugs. Among these, the rebound effect represents a common side effect to numerous classes of modern drugs, may cause serious and fatal disorders in patients. This review aims to clarify the health professionals on clinical and epidemiological aspects of rebound phenomenon. A qualitative, exploratory and bibliographic review was held in the PubMed database using the keywords 'rebound', 'withdrawal', 'paradoxical', 'acetylsalicylic acid', 'anti-inflammatory', 'bronchodilator', 'antidepressant', 'statin', 'proton pump inhibitor' and 'bisphosphonate'. The rebound effect occurs after discontinuation of numerous classes of drugs that act contrary to the disease disorders, exacerbating them at levels above those prior to treatment. Regardless of the disease, the drug and duration of treatment, the phenomenon manifests itself in a small proportion of susceptible individuals. However, it may cause serious and fatal adverse events should be considered a public health problem in view of the enormous consumption of drugs by population. Bringing together a growing and unquestionable body of evidence, the physician needs to have knowledge of the consequences of the rebound effect and how to minimize it, increasing safety in the management of modern drugs. On the other hand, this rebound can be used in a curative way, broadening the spectrum of the modern therapeutics. Copyright © 2012 Elsevier Editora Ltda. All rights reserved.

    Patients with knee osteoarthritis experience pain and functional impairment, which impacts upon activities of daily living ultimately leading to a loss of functional independence and low quality- of-life. This study therefore aimed at evaluating the functional health status of patients with knee osteoarthritis in the Family Medicine clinic, University College Hospital, Ibadan, Nigeria. A cross-sectional study was conducted on 270 eligible respondents between January and March 2011. The Ibadan Knee/Hip Osteoarthritis Measure (IKHOAM) was administered after screening with the knee pain screening tool (KNEST). Respondents'Socio- demographic characteristics and knee pain intensity ratings were also recorded. The age range of respondents in the study was from 28 years to 85 years with a female: male ratio 5:1. Out of the 270 respondents studied, 146 (54.1%) reported restriction in performing duties at work. One hundred and twenty seven respondents (47.0%) needed some assistance in walking outside the house for 15 to 20 minutes, whilst 195 (72.2%) required some assistance in climbing stairs. Thirty four (12.6%) of Muslims and 77 (28.5%) of Christians could not kneel to pray. Males are twice more likely to have a better functional health than females (OR= 2.1, 95% CI= 1.0- 4.6, p=0.046). Knee osteoarthritis significantly impairs activities of daily living, especially some socio-cultural and religious practices of respondents. Therefore in addition to treating the knee symptoms, removing environmental barriers may reduce immobility within and outside the home thereby improving functionality.

    Current models of chronic pain recognize that psychosocial factors influence pain and the effects of pain on daily life. The role of such factors has been widely studied on English-speaking individuals with chronic pain. It is possible that the associations between such factors and adjustment may be influenced by culture. This study sought to evaluate the importance of coping responses, self-efficacy beliefs, and social support to adjust to chronic pain in a sample of Portuguese patients, and discuss the findings with respect to their similarities and differences from findings of studies on English-speaking individuals. Measures of pain intensity and interference, physical and psychological functioning, coping responses, self-efficacy, and satisfaction with social support were administered to a sample of 324 Portuguese patients with chronic musculoskeletal pain. Univariate and multivariate analyses were computed. Findings were interpreted with respect to those from similar studies using English-speaking individuals. Coping responses and perceived social support were significantly associated with pain interference and both physical and psychological functioning; self-efficacy beliefs were significantly associated with all criterion variables. All coping responses, except for task persistence, were positively associated with pain interference and negatively associated with physical and psychological functioning, with the strongest associations found for catastrophizing, praying/hoping, guarding, resting, asking for assistance, and relaxation. The findings provide support for the importance of the psychosocial factors studied in terms of adjustment to chronic pain in Portuguese patients, and also suggest the possibility of some differences in the role of these factors due to culture.

    BACKGROUND A significant body of research suggests that religious involvement is related to better mental and physical health. Religion or spirituality was identified as an important health protective factor by women participating in the East Side Village Health Worker Partnership (ESVHWP), a community-based participatory research initiative on Detroit's east side. However, relatively little research to date has examined the mechanisms through which religion may exert a positive effect on health. OBJECTIVE The research presented here examines the direct effects of different forms of religious involvement on health, and the mediating effects of social support received in the church as a potential mechanism that may account for observed relationships between church attendance and health. DESIGN This study involved a random sample household survey of 679 African-American women living on the east side of Detroit, conducted as part of the ESVHWP. MAIN RESULTS Results of multivariate analyses show that respondents who pray less often report a greater number of depressive symptoms, and that faith, as an important source of strength in one's daily life, is positively associated with chronic conditions such as asthma or arthritis. Tests of the mediating effect of social support in the church indicated that social support received from church members mediates the positive relationship between church attendance and specific indicators of health. CONCLUSIONS These findings are consistent with the hypothesis that one of the major ways religious involvement benefits health is through expanding an individual's social connections. The implications of these findings for research and practice are discussed. PMID:12848838

    To examine the prevalence of religious beliefs and practices among medically ill hospitalized older adults and relate them to social, psychological and health characteristics. Consecutive patients age 60 or over admitted to the general medicine cardiology and neurology services of Duke University Medical Center were evaluated for participation in a depression study. As part of the evaluation, information on religious affiliation, religious attendance, private religious activities, intrinsic religiosity and religious coping was collected. Demographic, social, psychological and physical health characteristics were also assessed. Bivariate and multivariate correlates of religious belief and activity were examined using Pearson correlation and linear regression. Of the 542 patients evaluated, detailed information on religious beliefs and behaviors was collected on 455 cognitively unimpaired patients. Over one-half (53.4%) of the sample reported attending religious services once per week or more often; 58.7% prayed or studied the Bible daily or more often; over 85% of patients held intrinsic religious attitudes; and over 40% spontaneously reported that their religious faith was the most important factor that enabled them to cope. Religious variables were consistently and independently related to race (Black), lower education, higher social support and greater life stressors, and religious attendance was associated with less medical illness burden. Religious attendance was also related to lower depressive symptoms, although the association weakened when other covariates were controlled. Religious practices, attitudes and coping behaviors are prevalent among hospitalized medically ill older adults and are related to social, psychological and physical health outcomes. Implications for clinical practice are discussed.

  20. Persistent Memory in Single Node Delay-Coupled Reservoir Computing.

    Delays are ubiquitous in biological systems, ranging from genetic regulatory networks and synaptic conductances, to predator/pray population interactions. The evidence is mounting, not only to the presence of delays as physical constraints in signal propagation speed, but also to their functional role in providing dynamical diversity to the systems that comprise them. The latter observation in biological systems inspired the recent development of a computational architecture that harnesses this dynamical diversity, by delay-coupling a single nonlinear element to itself. This architecture is a particular realization of Reservoir Computing, where stimuli are injected into the system in time rather than in space as is the case with classical recurrent neural network realizations. This architecture also exhibits an internal memory which fades in time, an important prerequisite to the functioning of any reservoir computing device. However, fading memory is also a limitation to any computation that requires persistent storage. In order to overcome this limitation, the current work introduces an extended version to the single node Delay-Coupled Reservoir, that is based on trained linear feedback. We show by numerical simulations that adding task-specific linear feedback to the single node Delay-Coupled Reservoir extends the class of solvable tasks to those that require nonfading memory. We demonstrate, through several case studies, the ability of the extended system to carry out complex nonlinear computations that depend on past information, whereas the computational power of the system with fading memory alone quickly deteriorates. Our findings provide the theoretical basis for future physical realizations of a biologically-inspired ultrafast computing device with extended functionality.

    Physicians' spiritual and religious identities, beliefs, and practices are beginning to be explored. The objective of this study was to gather descriptive information about personal religion and spirituality from a random sample of academic American pediatricians and to compare this information with similar data from the public. In 2005, a Web-based survey of a random sample of 208 pediatrician faculty from 13 academic centers ranked by the US News & World Report as "honor roll" hospitals was conducted. Surveys elicited information about personal beliefs and practices as well as their influence on decisions about patient care and clinical practice. Multiple questions were replicated from the General Social Survey to enable comparisons with the public. Descriptive statistics were generated, and logistic regression analyses were conducted on relevant variables. Nearly 88% of respondents were raised in a religious tradition, but just 67.2% claimed current religious identification. More than half (52.6%) reported praying privately; additional spiritual practices reported included relaxation techniques (38.8%), meditation (29.3%), sacred readings (26.7%), and yoga (19%). The majority of academic pediatricians (58.6%) believed that personal spiritual or religious beliefs influenced their interactions with patients/colleagues. These odds increased 5.1-fold when academic pediatricians attended religious services monthly or more (P < .05). Compared with the American public, a notably smaller proportion of academic pediatricians reported a personal religious identity. The majority believed spiritual and religious beliefs influenced their practice of pediatrics. Whether secular or faith-based belief systems measurably modify academic pediatric practice is unknown.

  2. Three cases of pulmonary thromboembolism and extensive prayer (invocation) activity as a new possible risk factor.

    Pulmonary thromboembolism (PTE) is caused when thrombi are detached from the deep vein of the lower leg. In the field of forensic medicine, it is a well-known cause of sudden death. It has been reported that risk factors for PTE include surgery, trauma, extensive bed rest, and malignant neoplasm, among others; in addition, long-haul air travel is associated with a slightly increased risk for PTE, though such cases are rare. Recently, PTE had been reported in association with different conditions, such as ethrombosis, seated immobility thromboembolism, driving for long periods, and after traveling. The authors performed autopsies on 3 patients who died suddenly after 3 to 4 days of prayer in a prayer center or hermitage. It was confirmed that all deaths were caused by thrombi that had developed in the deep vein, obstructing the pulmonary artery. It was concluded that during repeated praying activities over an extensive time period, the kneeling position might have caused PTE. It is also possible that dehydration due to fasting may affect the formation of thrombi. According to the literature, PTE cases developed in association with prayer activity and position have not been reported to date, and so PTE caused by prayer activity is thought to be a new type of PTE developed in association with a certain life style. Therefore, people should be advised that a position involving a long period of immobilization, including long periods of prayer, could raise the risk of PTE. In addition, social policies to prevent the development of this kind of PTE are needed.

    While adolescents and adults with sickle cell disease (SCD) have reported using religion to cope with SCD, there is no data examining religious coping in young children with SCD. The purpose of this qualitative study was to: (1) describe the types of religious coping used by children with SCD; (2) describe the content and frequency of prayer used in relation to SCD; and (3) examine how children viewed God/Higher Power in relation to their SCD. Children with SCD participated in a semi-structured interview and an art drawing exercise focused on the use of general coping and religious coping. Interviews were coded, organized, and analyzed using a template organizational style of interpretation and NVivo 8.0 qualitative software. Of the 19 participants, the average age was 8.05 years (SD ±1.81); 11 were female (58%); all (100%) were African-American and 9 (47%) were Protestant. Children used religion to gain control, make meaning, and find comfort. Most children reported praying to get well, to keep from getting sick, and to get out of the hospital. Children described a functional God who made them take their medicine or took them to the hospital and an emotional God who made them happy and comforted them when they were sad or scared. These children with SCD reported using religion to help cope with the illness. Providers should be aware of the importance of religion to many of these children and integrate religion, as appropriate, into discussions about coping with SCD.

    Leukaemias and lymphomas are the most common malignant diseases diagnosed among adolescents and they are associated with pain and anxiety. As a result they may affect the way patients accept their disease and determine subjective assessment of quality of life. The objective of this study was to recognise strategies for coping with pain, evaluate the process of accepting the disease and assess quality of life among adolescents diagnosed with hematopoietic malignancies. The study group comprised 66 patients aged between 14 and 21 and diagnosed with leukaemia or lymphoma. The following measuring tools were used: the Pain Coping Strategies Questionnaire (CSQ), Zung Self-Rating Anxiety Scale (SAS), Acceptance of Illness Scale (AIS), and WHOQOL-BREF for quality of life evaluation. Coping self-statements and praying or hoping were the two most common strategies used by our respondents when coping with pain. In the study group the level of anxiety had no influence on pain control and the ability to reduce it. A statistically significant relation was found between the level of catastrophizing as a method of coping with pain and quality of life in the physical domain. An additional correlation was observed between quality of life in the psychological domain and the level of pain control. The ability of coping with pain promotes the acceptance of illness and improves patient's quality of life. The age and duration of the disease were factors affecting strategies for coping with pain. A small percentage of respondents who experienced anxiety suggests that further and deeper research is needed in this field.

    OBJECTIVE To provide an evidence-based clinical practice guideline for the chiropractic cervical treatment of adults with acute or chronic neck pain not due to whiplash. This is a considerable health concern considered to be a priority by stakeholders, and about which the scientific information was poorly organized. OPTIONS Cervical treatments: manipulation, mobilization, ischemic pressure, clinic- and home-based exercise, traction, education, low-power laser, massage, transcutaneous electrical nerve stimulation, pillows, pulsed electromagnetic therapy, and ultrasound. OUTCOMES The primary outcomes considered were improved (reduced and less intrusive) pain and improved (increased and easier) ranges of motion (ROM) of the adult cervical spine. EVIDENCE An “extraction” team recorded evidence from articles found by literature search teams using 4 separate literature searches, and rated it using a Table adapted from the Oxford Centre for Evidence-based Medicine. The searches were 1) Treatment; August, 2003, using MEDLINE, CINAHL, AMED, MANTIS, ICL, The Cochrane Library (includes CENTRAL), and EBSCO, identified 182 articles. 2) Risk management (adverse events); October, 2004, identified 230 articles and 2 texts. 3) Risk management (dissection); September, 2003, identified 79 articles. 4) Treatment update; a repeat of the treatment search for articles published between September, 2003 and November, 2004 inclusive identified 121 articles. VALUES To enable the search of the literature, the authors (Guidelines Development Committee [GDC]) regarded chiropractic treatment as including elements of “conservative” care in the search strategies, but not in the consideration of the range of chiropractic practice. Also, knowledge based only on clinical experience was considered less valid and reliable than good-caliber evidence, but where the caliber of the relevant evidence was low or it was non-existent, unpublished clinical experience was considered to be equivalent to

    Abstract Background: Health care providers' lack of education on spiritual care is a significant barrier to the integration of spiritual care into health care services. Objective: The study objective was to describe the training program, Clinical Pastoral Education for Healthcare Providers (CPE-HP) and evaluate its impact on providers' spiritual care skills. Methods: Fifty CPE-HP participants completed self-report surveys at baseline and posttraining measuring frequency of and confidence in providing religious/spiritual (R/S) care. Four domains were assessed: (1) ability and (2) frequency of R/S care provision; (3) comfort using religious language; and (4) confidence in providing R/S care. Results: At baseline, participants rated their ability to provide R/S care and comfort with religious language as “fair.” In the previous two weeks, they reported approximately two R/S patient conversations, initiated R/S conversations less than twice, and prayed with patients less than once. Posttraining participants' reported ability to provide spiritual care increased by 33% (p<0.001). Their comfort using religious language improved by 29% (p<0.001), and frequency of R/S care increased 75% (p<0.001). Participants reported having 61% more (p<0.001) R/S conversations and more frequent prayer with patients (95% increase; p<0.001). Confidence in providing spiritual care improved by 36% overall, by 20% (p<0.001) with religiously concordant patients, and by 43% (p<0.001) with religiously discordant patients. Conclusions: This study suggests that CPE-HP is an effective approach for training health care providers in spiritual care. Dissemination of this training may improve integration of spiritual care into health care, thereby strengthening comprehensive patient-centered care. PMID:25871494

  7. The Use of Religious Coping Methods in a Secular Society: A Survey Study Among Cancer Patients in Sweden.

    In the present article, based on results from a survey study in Sweden among 2,355 cancer patients, the role of religion in coping is discussed. The survey study, in turn, was based on earlier findings from a qualitative study of cancer patients in Sweden. The purpose of the present survey study was to determine to what extent results obtained in the qualitative study can be applied to a wider population of cancer patients in Sweden. The present study shows that use of religious coping methods is infrequent among cancer patients in Sweden. Besides the two methods that are ranked in 12th and 13th place, that is, in the middle (Listening to religious music and Praying to God to make things better), the other religious coping methods receive the lowest rankings, showing how nonsignificant such methods are in coping with cancer in Sweden. However, the question of who turns to God and who is self-reliant in a critical situation is too complicated to be resolved solely in terms of the strength of individuals' religious commitments. In addition to background and situational factors, the culture in which the individual was socialized is an important factor. Regarding the influence of background variables, the present results show that gender, age , and area of upbringing played an important role in almost all of the religious coping methods our respondents used. In general, people in the oldest age-group, women, and people raised in places with 20,000 or fewer residents had a higher average use of religious coping methods than did younger people, men, and those raised in larger towns.

    Decreased ability to accomplish significant leisure activities often occurs in early stages of dementia of Alzheimer type (DAT). As a long term effect, it may eventually affect the quality of life of the patient as well as that of the caregiver's. In a previous study, a woman with early DAT (77 years old, MMSE: 24/30) improved her participation in 2 leisure activities (listening to music and praying in a group) following the learning of a few tasks (e.g. using a radio cassette, remembering the significance of an pre-programmed ring) as a result of a cognitive intervention. The present study presents the long term effect of this intervention on the retention of the learned tasks and on spontaneous participation in both leisure activities of her daily living. Measures of tasks' learning and spontaneous participation in activities have been obtained through direct observation (ex: ability to use the tasks learned without assistance) and telephone conversations with the caregiver. The measures were taken 9 to 15 months post-intervention. Nine months after the end of the intervention, the participant could no longer use the radio cassette, but was able to remember the significance of the pre-programmed ring. Similarly, she stopped listening to music, but still attended her prayer group. The intervention appears to maintain participation in a leisure activity for several months in a patient with early DAT, in spite of expected functional decline. This functional impact can be achieved through retention of specific learned tasks as well as by strong external cues (daily pre-programmed ring), and can increase the quality of life for patients with DAT.

    This qualitative research sought answers to questions about how elders in Agate, Ghana, coped with the challenges of illness in a rural village and in particular how they negotiated treatment for their illnesses within a flawed and limited healthcare system. In our study, 22 of 28 interviewees used all methods available to them (biomedical approaches [doctors and/or hospitals and/or doctor-prescribed medications], herbs, over-the-counter medicines [i.e., acetaminophen painkillers], and faith-based methods [praying/fasting/laying of hands/holy food and/or water]) in attempts to heal their illnesses. A syncretism existed in the negotiation of treatment options. All participants in our study used some form of what we term "Treatment Blending" (TBL), the use by a single participant of more than one of the aforementioned treatment methods for illness. Our research also revealed a widespread use of multiple spiritual systems (at the same time) and practitioner overlap (visiting a doctor, a traditional healer, and/or Christian pastor). Elders, in multiple cases, demonstrated the daily practice of one religion while seeking healing through another framework. TBL among our participants was a reflection of the lives elders lead in which illness and healing cannot be separated from the spiritual, the idea of an omnipresent God who is the ultimate "doctor," and ancient African traditions of herbs and rituals that possess deeper meaning for both physical and psychological healing and well-being. This ran parallel with the syncretism of religion itself in Ghana and suggests possible related paths through which to improve the healthcare system for elders in rural Ghana utilizing local faith-based groups and the elders themselves to assist.

    This paper presents the personal accounts of Darfuri students studying at Ahfad University for Women in Omdurman, Sudan. Their war-related exposure, current ongoing life challenges, emotional distress, and coping strategies were explored using a semistructured interview protocol with a sample of 20 students. Through interpretative phenomenological analysis (IPA), the Darfuri students' stories illustrated that they were exposed to an array of traumatic war events, including personal experiences of parental separation, injury and death of family members, and shortages of essential life-sustaining supplies in internally displaced camps. Also, they were confronted with myriad current life hassles and urban-cultural challenges, including being physically distant from their families, and losing the shelter of parents, the encouragement of extended family members, and their rich and familiar social support networks. Urban-cultural challenges and lack of environmental mastery applied to most Darfuri participants as they relocated to Omdurman city, which included negotiating an unfamiliar transport system, learning the routes and directions to important city landmarks, and insufficient funds for basic hygienic essentials. Emotional distress reactions were coded by forming two distinct lists: directly mentioned by the participant; and observations of emotional manifestation during the interview. Patterns emerged that may be similar to symptoms of mood and anxiety disorders; for example, the DSM-IV criteria for symptoms of generalized anxiety disorder and major depression. Strong religious practices and beliefs (such as praying and reading the Quran), ability to form interpersonal relationships, availability of social support networks, and a positive future outlook seemed to augment their ability to cope with their subsequent emotional distress owing to war-related exposures, current ongoing life hassles and urban-cultural challenges.

    In four large, nationally representative surveys (N = 11.2 million), American adolescents and emerging adults in the 2010s (Millennials) were significantly less religious than previous generations (Boomers, Generation X) at the same age. The data are from the Monitoring the Future studies of 12th graders (1976-2013), 8th and 10th graders (1991-2013), and the American Freshman survey of entering college students (1966-2014). Although the majority of adolescents and emerging adults are still religiously involved, twice as many 12th graders and college students, and 20%-40% more 8th and 10th graders, never attend religious services. Twice as many 12th graders and entering college students in the 2010s (vs. the 1960s-70s) give their religious affiliation as "none," as do 40%-50% more 8th and 10th graders. Recent birth cohorts report less approval of religious organizations, are less likely to say that religion is important in their lives, report being less spiritual, and spend less time praying or meditating. Thus, declines in religious orientation reach beyond affiliation to religious participation and religiosity, suggesting a movement toward secularism among a growing minority. The declines are larger among girls, Whites, lower-SES individuals, and in the Northeastern U.S., very small among Blacks, and non-existent among political conservatives. Religious affiliation is lower in years with more income inequality, higher median family income, higher materialism, more positive self-views, and lower social support. Overall, these results suggest that the lower religious orientation of Millennials is due to time period or generation, and not to age.

    Zambia is experiencing high prevalence of childhood cancer. However, very few children access and complete treatment for cancer. This study aimed to document the challenges for health care providers, parents and patients who face a child hood cancer diagnosis in Zambia, and their coping strategies. This was an exploratory health facility-based qualitative study that was conducted at a Paediatric oncology ward at referral hospital in Zambia. In-depth individual interviews conducted with fifteen (15) caregivers and seven (7) key informants were analysed using thematic analysis. Several challenges related to managing the childhood cancer diagnosis were recorded. Individual and family challenges were inadequate knowledge on childhood cancer, lack of finances to meet treatment and transport costs as well as long period of hospitalisation that affected women's ability to perform multiple responsibilities. Whereas challenges at community level were inadequate support to address emotional and physical distress and social stigmatisation experienced by caregivers. Health systems issues included inadequate specialised health workers, poor communication among health workers, limited space and beds as well as insufficient supplies such as blood. Cultural related factors were the belief that cancer is a product of witchcraft as well as religious beliefs regarding the role of faith healing in childhood cancer treatment. Coping strategies used by parents/ caregivers included praying to God, material support from organisations and church as well as delaying having another child. Addressing the challenges for health care providers, parents and patients who face a childhood cancer diagnosis may require adopting a systems or an ecological approach that allows developing strategies that simultaneously address challenges related to the individual, family, community, health system and cultural aspects.

    Hope is an important coping resource for cancer patients. Types and sources of hope and hope- inspiring strategies are not well investigated among Iranian cancer patients. The aims of present study were therefore to investigate the nature of hope and some demographic predictors of hope among Iranian cancer patients. This descriptive-correlational study was undertaken among 200 cancer patients admitted to an educational center affiliated to Ardabil University of Medical Sciences, Iran. Participants were selected using a convenience sampling method. The Herth Hope Index and other validated questionnaires were used to investigate level of hope and types and sources of hope, as well as hope-inspiring strategies. Data were analyzed using SPSS statistical software. The overall score for hope was 31 from total scores ranging between 12 and 48. Some 94% of patients mentioned 'return to normal life' and 'complete healing of disease by drugs and physicians' as their main hopes. The most important sources of hope reported by patients include spiritual resources, family members, healthcare workers, and medicines and treatments available for the disease. Relationship with God, praying/blessing, controlling the signs and symptoms of the disease, and family/health care workers' support were the main hope-inspiring strategies. Patients who had a history of metastasis, or who were older, illiterate, divorced/widowed and lived with their children reported lower levels of hope. On the other hand, employed patients and those with good support from their families had higher levels of hope. The study findings showed moderate to high levels of hope among Iranian cancer patients. Accordingly, the role of spiritual/religion, family members and health care workers should be considered in developing care plans for these patients.

Twice as many 12th graders and entering college students in the 2010s (vs. the 1960s–70s) give their religious affiliation as “none,” as do 40%–50% more 8th and 10th graders. Recent birth cohorts report less approval of religious organizations, are less likely to say that religion is important in their lives, report being less spiritual, and spend less time praying or meditating. Thus, declines in religious orientation reach beyond affiliation to religious participation and religiosity, suggesting a movement toward secularism among a growing minority. The declines are larger among girls, Whites, lower-SES individuals, and in the Northeastern U.S., very small among Blacks, and non-existent among political conservatives. Religious affiliation is lower in years with more income inequality, higher median family income, higher materialism, more positive self-views, and lower social support. Overall, these results suggest that the lower religious orientation of Millennials is due to time period or generation, and not to age. PMID:25962174

    In the present article, based on results from a survey study in Sweden among 2,355 cancer patients, the role of religion in coping is discussed. The survey study, in turn, was based on earlier findings from a qualitative study of cancer patients in Sweden. The purpose of the present survey study was to determine to what extent results obtained in the qualitative study can be applied to a wider population of cancer patients in Sweden. The present study shows that use of religious coping methods is infrequent among cancer patients in Sweden. Besides the two methods that are ranked in 12th and 13th place, that is, in the middle (Listening to religious music and Praying to God to make things better), the other religious coping methods receive the lowest rankings, showing how nonsignificant such methods are in coping with cancer in Sweden. However, the question of who turns to God and who is self-reliant in a critical situation is too complicated to be resolved solely in terms of the strength of individuals’ religious commitments. In addition to background and situational factors, the culture in which the individual was socialized is an important factor. Regarding the influence of background variables, the present results show that gender, age, and area of upbringing played an important role in almost all of the religious coping methods our respondents used. In general, people in the oldest age-group, women, and people raised in places with 20,000 or fewer residents had a higher average use of religious coping methods than did younger people, men, and those raised in larger towns.

  17. Astronomy at the service of the Islamic society

    The Islamic society has great ties to astronomy. Its main religious customs (start of the Islamic month, direction of prayer, and the five daily prayers) are all related to two main celestial objects: the Sun and the Moon. First, the start of any Islamic month is related to the actual seeing of the young crescent after the new Moon. Second, the direction of prayer, i.e., praying towards Mecca, is related to the determination of the zenith point in Mecca. Third, the proper time for the five daily prayers is related to the motion of the Sun. Everyone in the society is directly concerned by these customs. This is to say that the major impetus for the growth of Islamic astronomy came from these three main religious observances which presented an assortment of problems in mathematical astronomy. To observe these three customs, a new set of astronomical observations were needed and this helped the development of the Islamic observatory. There is a claim that it was first in Islam that the astronomical observatory came into real existence. The Islamic observatory was a product of needs and values interwoven into the Islamic society and culture. It is also considered as a true representative and an integral par of the Islamic civilisation. Since astronomy interested not only men of science, but also the rulers of the Islamic empire, several observatories have flourished. The observatories of Baghdad, Cairo, Córdoba, Toledo, Maragha, Samarqand and Istanbul acquired a worldwide reputation throughout the centuries. This paper will discuss the two most important observatories (Maragha and Samarqand) in terms of their instruments and discoveries that contributed to the establishment of these scientific institutions.

    In the Name of Allah, the Most Beneficent, the Most Merciful. It is with great pleasure that I welcome the participants of the International Conference of Mechanical Engineering Research 2011. The Prophet Muhammad (peace be upon him) said 'Acquire knowledge and impart it to the people.' (Al Tirmidhi). The quest for knowledge has been from the beginning of time but knowledge only becomes valuable when it is disseminated and applied to benefit humankind. It is hoped that ICMER 2011 will be a platform to gather and disseminate the latest knowledge in mechanical engineering. Academicians, Scientist, Researchers and practitioners of mechanical engineering will be able to share and discuss new findings and applications of mechanical engineering. It is envisaged that the intellectual discourse will result in future collaborations between universities, research institutions and industry both locally and internationally. In particular it is expected that focus will be given to issues on environmental and energy sustainability. Researchers in the mechanical engineering faculty at UMP have a keen interest in technology to harness energy from the ocean. Lowering vehicle emissions has been a primary goal of researchers in the mechanical engineering faculty and the automotive engineering centre as well including developing vehicles using alternative fuels such as biodiesel and renewable sources such as solar driven electric vehicles. Finally I would like to congratulate the organizing committee for their tremendous efforts in organizing the conference. As I wrote this in the Holy Land of Makkah, I pray to Allah swt that the conference will be a success.

    Objective Compare pain-related measures and psychosocial variables between glutamate-evoked jaw muscle pain in healthy subjects (HS) and patients with persistent myofascial temporomandibular disorder (TMD) pain. Design 47 female HS and 10 female patients with persistent myofascial TMD pain participated. The HS received an injection of glutamate into the masseter muscle to model persistent myofascial TMD pain. Participants filled out a coping strategies questionnaire (CSQ), the symptom checklist 90 (SCL-90) and McGill Pain Questionnaire (MPQ). Pain intensity was assessed on an electronic visual analog scale (VAS). Pain-drawing areas, Numerical Rating Scale (NRS) scores of unpleasantness, pressure pain thresholds (PPT) and tolerance (PPTOL) were measured. Unpaired t-tests and correlation tests were used for analyses. Results The groups were significantly different when comparing the CSQ scores of control, decrease, diverting attention, increase of behavioral activities and somatization. The peak VAS pain, NRS of unpleasantness and MPQ scores were not significantly different between groups, but PPT and PPTOL were significantly lower in the TMD patients. Significant positive correlations were found in the TMD patients between peak VAS pain and CSQ catastrophizing score and SCL-90 somatization. The scores of PPTs and PPTOLs, in patients showed positive correlations with CSQ reinterpreting pain sensations scores and PPTs correlated with CSQ praying/hoping scores. Conclusions Glutamate-evoked pain responses in HS and persistent myofascial TMD pain have similar sensory-discriminative and affective-unpleasantness components but differ in psycho-social features. This study suggests that experimental designs based on glutamate injection into muscle can provide an appropriate model for elucidating persistent myofascial pain conditions. PMID:18313028

    Polycyclic Aromatic Hydrocarbon (PAH) molecules carry the infrared emission features which dominate the spectra of most galactic and extragalactic sources. Our study investigates the chemical evolution, chemical properties, physical properties, thermal stability, and photostability of samples produced from the UV-irradiation of simulated mineral dust grains coated with aromatics and astrobiologically relevant ices, using infrared spectroscopy. We investigate the chemical evolution of aromatic organics via anhydrous (no H2O ice) and hydrous (H2O ice) mechanisms. The anhydrous mechanism involves UV-induced catalytic reactions between organics and dense-cloud mineral grains, whereas the hydrous mechanism incorporates H2O-rich ice mixtures with the minerals and organics. These investigations identify the chemical and physical interactions occurring between the organic species, the dust grains and water-rich ices.These laboratory simulations also generate observable IR spectroscopic parameters for future astronomical observations with infrared telescopes such as SOFIA and JWST as well as provide empirical parameters for input into astronomical models of the early stages of planetary formation. These studies give us a deeper understanding of the potential catalytic pathways mineral surfaces provide and a deeper understanding of the role of ice-organic compositions in the chemical reaction pathways and how these processes fit into the formation of new planetary systems.In order to achieve these goals we use the Harrick ‘Praying Mantis’ Diffuse Reflectance Accessory (DRIFTS), which allows FTIR measurements of dust samples under ambient conditions by measuring the light scattered by the dust sample. We have also incorporated a low -temperature reaction chamber permitting the DRIFTS measurements at low temperatures and high-vacuum. This set-up permits the analysis of the solid particles surfaces revealing the chemical species adsorbed as well as their chemical evolution

    We investigated whether faith was associated with a difference in time to incident metabolic syndrome (MetS) among midlife Hispanic women vs women of other ethnicities. The Study of Women's Health Across the Nation (SWAN) is a community-based, longitudinal study of a cohort of midlife women. Social, demographic, psychosocial, anthropometric, medical, and physiological measures, and incident MetS were assessed in near-annual intervals using questionnaires and assays. Each participant answered key questions related to religion and meaning in her life. Differences in time to MetS were modeled by Hispanic ethnicity (vs. otherwise) among women reporting low and high levels of faith. Incident MetS in the 7 years after the SWAN baseline assessment. Among 2371 women, average baseline age 46, Hispanic women (n = 168) were more likely to have higher perceived stress and financial strain than non-Hispanic women (n = 2203). Nevertheless, Hispanic women were far more likely than non-Hispanic women to report that faith brought them strength and comfort in times of adversity, that they prayed often, and that their faith was sustaining for them. Hispanic women had the highest incidence rate of MetS of any racial/ethnic group. However, among women with high levels of faith, the incidence rate of MetS was similar in the Hispanic and non-Hispanic groups. Conversely, among women with low levels of faith, Hispanic women had a faster progression to MetS than did non-Hispanic women. Faith might be associated with a different risk of MetS among women of Hispanic vs other ethnicities. Among women who are not part of a faith community, Hispanic ethnicity might be a risk factor for MetS. Copyright © 2018 Elsevier B.V. All rights reserved.

    Women are at risk of violence at all stages of their life, including during pregnancy. Using a interviewer-administered questionnaire, 306 pregnant women were interviewed in two public secondary health facilities in Ibadan to compare prevalence and risk factors of VAW before and during pregnancy. Prevalence ofVAW a year before current pregnancy was 41.5% compared to 17.7% during pregnancy. Perpetrators before pregnancy were mostly relatives (22%), while during pregnancy, partners (64%). Major reasons for violence were "not obeying instructions" (33.3%) and "misbehaving" (26%). Education (OR 0.49; 95% CI 0.29-0.83) and polygamous union (OR 9.56; 95% CI 3.71-24.63) and consumption of alcohol (OR 7.19; 95% CI 0.04-0.53) were statistically significant a year before pregnancy. Mothers occupation (OR 0.19; 95% CI 1.05-4.49); type of union (OR14.13; 95% CI 6.13-32.59), alcohol consumption by partner (OR 6.06; 95% CI 0.05-0.54); and not wanting pregnancy (OR 3.53; 95% CI 1.20-9.30) were statistically significant in the index pregnancy. Hemorrhage (7.4% vs. 4.8%), abortion (1.9% vs. 1.2%), intrauterine death (3.7% vs. 1.2%) and premature labour (9.3% vs. 3.2%) were more often found in women who experienced VAW than those who did not, the latter was statistically significant (P < 0.05). Violence avoidance strategies included 'playing along' (51.3%) and 'praying' (21%). Pregnancy was protective against VAW. Empowerment of women through education and employment is crucial. Counselling on planning of families is also necessary. Screening for violence in pregnancy and close monitoring of the abused to ensure good obstetric outcome is recommended.

  3. Divination, prognosis and prophylaxis: the Hippocratic work 'on dreams' (De victu 4) and its Near Eastern background.

    2004-01-01

    Building on the results of recent scholarship concerning the coherence of the Hippocratic work De victu ('On Regimen'), this chapter discusses the close connections between Book 4, which deals with the use of dreams for medical prognosis and especially prophylaxis (which the author claims to be his own innovation), with the rest of the work. It analyses the author's position on dreams and their interpretation and his stance against professional dream interpreters. It distinguishes five categories in the author's discussion: 1. the signs, i.e. the dream images themselves; 2. the significance of the dreams; 3. explanations of the relationship between sign and significance; 4. prophylactic (dietetic) measures to prevent disease; 5. instructions as to the gods one should pray to in order to prevent disease. It explores the rationale underlying these categories and lists a number of parallels with Babylonian dream literature. It concludes that although there are important differences with respect to the use of dreams in Babylonian medicine, it is not implausible that the author of De victu 4 has borrowed some of his material from Near Eastern dream books. At the same time, the author of De victu 4 distances himself from oneiromantic practices that are very similar to what we find in Babylonia; and his elaborate interpretative system linking specific dreams to specific bodily disorders goes far beyond anything found in Near Eastern sources (but also beyond anything else in the Corpus Hippocraticum). He does accept the existence of dreams sent by the gods and of prayer to the gods in combination with dietetic prophylaxis; but his elaborate use of dietetics for preventive purposes marks an important innovation when compared to Babylonian medicine. The author is not concerned with incubation.

    Chronic pain is the frequent and significantly challenging complications in persons with spinal cord injury (SCI). Socio-cultural background may lead people perceive and manage pain differently. The study aims to describe the chronic pain experience and pain management of SCI persons in Nepal. A descriptive cross sectional study was conducted among purposively selected sample of 120 SCI persons with chronic pain living in the eight districts of Bagmati Zone of Nepal. The data were collected using the International Spinal Cord Injury Pain Basic Data Set Version 2 (ISCIPBDS-2) and Open-ended Pain Management Questionnaire. The data were analyzed using descriptive statistics and content analysis method. The back (n=84), lower legs/feet (n=63) and buttocks/hips (n=51) was found as the common pain locations. In common, the onset of pain was found within the first 6 month of the injury. Overall pain intensity and pain interference were found to be at the moderate level. The SCI persons used pain medications and non-pharmacological pain management. Ibuprofen was the commonly used pain medication and commonly used non-pharmacological pain management methods included physical support (e.g. massage, exercise), relaxation (e.g. distraction, substance abuse), coping (e.g. acceptance, praying), and traditional herbs. SCI persons had chronic pain experience which interfered with their daily living. They used pain medications and non-pharmacological pain management methods based on their beliefs, knowledge, and community resources in Nepal. This study provides some evidence to help the team of rehabilitation professional to plan and help SCI persons with chronic pain. Based on these findings, chronic pain management intervention for SCI persons should be developed and supported continuously from hospital to home based community context of Nepal.

    Background: Malnutrition and dehydration are two most common types of ailments residents of nursing homes (NH) prone to. It is very important to assess these problems because they can predispose the residents to severe illnesses. The aim of this study was to gather information on nutritional status and its associated risk factors in elderly residents of NHs in Tehran, Iran. Methods: From 16 NHs in Tehran, 263 residents were randomly selected. Data were collected via questionnaires, including demographic characteristics, past medical history, present health problems and daily routines. The MNA questionnaire was used to gather information regarding their nutritional status. Results: The present study showed that 10.3% of the elderly residents in nursing homes were malnourished. 66.4% of males and 70.8% of females were at risk of malnutrition. Multivariate analysis showed that after adjusting for confounders the following elderly-related factors were the independent risk factors of malnutrition: consuming half or less than of the food (OR=8.0, 95%CI=3.7–17.7), having no teeth or good prosthesis (OR=1.7, 95%CI=1.1–2.7), diabetes (OR=1.6, 95%CI=1.1–2.4), smoking (OR=0.6, 95%CI=0.3–1.2), studying (OR=0.4 95%CI=0.2–0.9) and praying in their free time (OR=1.8 95%CI=1.2–2.6). Conclusion: The subjects’ health-related factors and their free-time activities and nutritional behavior are the most important factors associated with poor nutrition among elderly residents of NHs; however, further investigation is needed to clarify the role of other factors in maintaining a suitable nutritional plan for them.

    The life of organisms in an ecosystem depends not only on abiotic factors, but also on the interaction of organisms in which they come with each other. The study of mechanisms of the bioregulation based on ecological - biochemical interactions of ecosystem links is necessary to know the ecosystem development, its stability, survival of ecosystem organisms. It is of high importance as for the creation of artificial ecosystems, and also for the study of natural ecosystems under anthropogenic pressure on them. To create well-functioning ecosystems is necessary to study and consider the basic types of relationships between organisms. The basic types of interactions between organisms have been studied with simple terrestrial and water ecosystems. 1. The interaction of microbiocenoses and plants were studied in experiments with agrocenoses. Microbiocenosis proposed for increase of productivity of plants and for obtaining ecologically pure production of plants has been created taking into account mutual relationships between species of microorganisms. 2. The experimental model of the atmosphere closed «autotroph - heterotroph» system in which heterotrophic link was the mixed population of yeasts (Candida utilis and Candida guilliermondii) was studied. The algae Chlorella vulgaris was used as an autotroph link. It was shown, that the competition result for heterotrophic link depended on strategy of populations of yeast in relation to a substrate and oxygen utilization. 3. As a result of experimental and theoretical modelling of a competition of algae Chlorella vulgaris and Scenedesmus quadricauda at continuous cultivation, the impossibility of their coexistence in the conditions of limitation on nitrogen was shown. 4. Pray-predator interactions between algae (Chlorella vulgaris, Scenedesmus quadricauda) and invertebrates (Paramecium caudatum, Brachionus plicatilis) were studied in experimental closed ecosystem.

    To ascertain health professionals' knowledge, attitudes and beliefs towards lesbian, gay, bisexual and transgender parents seeking health care for their children in a paediatric tertiary hospital setting which practises family-centred care. Lesbian, gay, bisexual and transgender parents are often reluctant to disclose their sexual orientation to health professionals for fear of discrimination and compromised quality of care. Staff knowledge, attitudes and beliefs can influence disclosure by parents, but little is known about knowledge, attitudes and beliefs in paediatric tertiary hospital staff towards lesbian, gay, bisexual and transgender parents accessing care for their children. Descriptive comparative study of health staff using a cross-sectional survey. A set of validated anonymous questionnaires was used to assess knowledge about homosexuality, attitudes towards lesbians and gay men, and gay affirmative practice. Three open-ended questions were also used to assess beliefs about encouraging disclosure of lesbian, gay, bisexual and transgender parenting roles and how this may impact on care. Of the 646 staff surveyed, 212 (32.8%) responded. Knowledge and attitudes were significantly associated with professional group, gender, Caucasian race, political voting behaviour, presence of religious beliefs, the frequency of attendance at religious services, the frequency of praying, and having a friend who was openly lesbian, gay, bisexual and transgender. This study highlighted that staff working in a tertiary paediatric hospital setting, with family-centred care models in place, held attitudes and beliefs that may impact on the experience of hospitalisation for lesbian, gay, bisexual and transgender parents, and the quality of care received by their children. To promote equitable care to all families, organisations should ensure that family-centred care policies and guidelines are adopted and appropriately implemented. In addition to formal education, affirmative

    Racial/ethnic differences with regard to complementary and alternative medicine (CAM) use have been reported in the US. However, specific details of CAM use by African Americans with rheumatoid arthritis (RA) are lacking. Data were collected from African Americans with RA enrolled in a multicenter registry regarding the use of CAM, including food supplements, topical applications, activities, and alternative care providers. Factors associated with CAM use by sex and disease duration were assessed using t-test, Wilcoxon's rank sum test, chi-square test, and logistic regression analyses. Of the 855 participants, 85% were women and mean age at enrollment was 54 years. Overall, ever using any of the CAM treatments, activities, and providers was 95%, 98%, and 51%, respectively (median of 3 for number of treatments, median of 5 for activities, and median of 1 for providers). Those with longer disease duration (>2 years) were significantly more likely (odds ratio ≥2.0, P < 0.05) to use raisins soaked in vodka/gin, to take fish oils, or to drink alcoholic beverages for RA treatment than those with early disease. As compared to men, women were significantly (P < 0.05) more likely to pray/attend church, write in a journal, and use biofeedback, but were less likely to smoke tobacco or topically apply household oils for treatment of RA. CAM use was highly prevalent in this cohort, even in individuals with early disease. Health care providers need to be aware of CAM use as some treatments may potentially have interactions with conventional medicines. This could be important within this cohort of African Americans, where racial disparities are known to affect access to conventional care. Copyright © 2014 by the American College of Rheumatology.

    The prayer ritual is an essential component of Islam that requires entry into a state of physical purity (wudhu) through ablution, which is invalidated by voiding. An important dilemma for patients and surgeons may arise when a Muslim patient is counselled on cystectomy because of the belief by some that an incontinent urinary diversion will automatically invalidate their wudhu. To determine if there are any religious barriers and implications for Muslim patients undergoing an incontinent urinary diversion. A questionnaire was distributed to all UK mosques, addressed to the imam (n=804). A total of 134 imams (response rate 16.7%) responded. There was general agreement among imams, with >90% answering that it is possible for a Muslim to perform ablution, pray, and enter a mosque with a urinary stoma. The majority of imams (86.6%) also stated that refusal of a urinary stoma was not justified by religious teachings. When asked if patients should choose the option of a neobladder despite this surgery having greater risk, 57.5% of respondents stated that they were either unsure or agreed with this alternative. The majority of imams agreed that Muslims with a urinary stoma are able to maintain their ablution, allowing them to conduct their daily prayers, and that this form of surgery should not be refused on religious grounds. Our study suggests that the consensus view is that a urinary stoma is not contraindicated with regard to the practice of Islamic prayer rituals. In this study we investigated if having a urinary stoma would be a religious barrier for Muslim patients in performing their obligatory prayer rituals. The overwhelming majority of imams stated that having a urinary stoma should not stop Muslim patients practising important aspects of their faith. Copyright © 2017 European Association of Urology.

    Objective To explore existential meaning-making in an ethnic-majority subgroup with mental ill health and to increase knowledge about the importance of gaining access to such information in mental healthcare. Design Qualitative study using in-depth interviews and systematic text condensation analysis. Participants 17 devote Christians with an ethnic-Swedish background, 12 women and 5 men, 30–73 years old, from different congregations across Sweden, having sought medical care for mental ill health of any kind. Setting The secular Swedish society. Results A living, although asymmetric, relationship with God often was seen as the most important relationship, giving hope and support when ill, but creating feelings of abandonment and fear if perceived as threatened. Symptoms were interpreted through an existential framework influenced by their view of God. A perceived judging God increased feelings of guilt, sinfulness and shame. A perceived merciful God soothed symptoms and promoted recovery. Existential consequences, such as being unable to pray or participate in congregational rituals, caused feelings of ‘spiritual homelessness’. Participants gave biopsychosocial explanations of their mental ill health, consonant with and sometimes painfully conflicting with existential explanations, such as being attacked by demons. Three different patterns of interaction among biopsychosocial and existential dimensions in their explanatory systems of illness causation were identified: (a) comprehensive thinking and consensus; (b) division and parallel functions and (c) division and competitive functions. Conclusions Prevailing medical models for understanding mental ill health do not include the individual's existential experiences, which are important for identifying risk and protective factors as well as possible resources for recovery. The various expressions of existential meaning-making identified in this devout religious subgroup illustrate that existential

    The main objective of the present work is to understand the processes used in emerging Catholic and Protestant religious interventions for recovery from drug dependence, from the vantage point of individuals subjected to them. A qualitative method and an intentional sample selected by criteria were adopted for this investigation, which was conducted in São Paulo, Brazil. An in-depth semi-structured interview was conducted with 57 predominantly male former drug users who fit the criteria: they had been submitted to non-medical religious treatments to treat dependence and were abstinent for at least 6 months. Crisis was found to be the main reason leading interviewees to seek treatment; this includes, losing family, losing employment, and experiencing severe humiliation. Evangelicals most used religious resources exclusively as treatment, showing strong aversion to the role of doctors and to any type of pharmacological treatment. A common feature of Catholic and Protestant groups is the importance ascribed to praying and talking to God, described by subjects as strongly anxiolytic, and a means to control drug craving. Confession and forgiveness, through faith conversion or penitences, respectively, appeal strongly to the restructuring of life and increase of self-esteem. Religious interventions were considered effective by the individuals who underwent them and were seen as attractive for the humane, respectful treatment they delivered. The key aspects of this type of treatment are social support provided by the receiving group, equal treatment, and instant, judgment-free acceptance. The success of these actions, then, is not only due to some "supernatural" aspect, as might be assumed, but also more to the unconditional dedication of human beings to their peers. Given the difficulty in treating drug dependence, religious interventions could be used as a complementary treatment for conventional therapies.

  12. Valuation of environmental quality and eco-cultural attributes in Northwestern Idaho: Native Americans are more concerned than Caucasians.

    PubMed

    Burger, Joanna

    2011-01-01

    Valuation of features of habitats and ecosystems usually encompasses the goods and services that ecosystems provide, but rarely also examine how people value ecological resources in terms of eco-cultural and sacred activities. The social, sacred, and cultural aspects of ecosystems are particularly important to Native Americans, but western science has rarely examined the importance of eco-cultural attributes quantitatively. In this paper I explore differences in ecosystem evaluations, and compare the perceptions and evaluations of places people go for consumptive and non-consumptive resource use with evaluations of the same qualities for religious and sacred places. Qualities of ecosystems included goods (abundant fish and crabs, butterflies and flowers, clean water), services (complexity of nature, lack of radionuclides that present a health risk), and eco-cultural attributes (appears unspoiled, scenic horizons, noise-free). Native Americans and Caucasians were interviewed at a Pow Wow at Post Falls, Idaho, which is in the region with the Department of Energy's Hanford Site, known for its storage of radioactive wastes and contamination. A higher percentage of Native American subjects engaged in consumptive and religious activities than did Caucasians. Native Americans engaged in higher rates of many activities than did Caucasians, including commune with nature, pray or meditate, fish or hunt, collect herbs, and conduct vision quests or other ceremonies. For nearly all attributes, there was no difference in the relative ratings given by Native Americans for characteristics of sites used for consumption/non-consumptive activities compared to religious/sacred places. However, Caucasians rated nearly all attributes lower for religious/sacred places than they did for places where they engaged in consumptive or non-consumptive activities. Native Americans were less concerned with distance from home for consumptive/non-consumptive activities, compared to religious

  13. A Schutzian Analysis of Prayer with Perspectives from Linguistic Philosophy.

    2017-01-01

    In this paper, we propose to analyze the phenomenon of Christian prayer by way of combining two different analytical frameworks. We start by applying Schutz's theories of "intersubjectivity," "inner time," "politheticality," and "multiple realities," and then proceed by drawing on the ideas and insights of linguistic philosophers, notably, Wittgenstein's "language-game," Austin's "speech act," and Evans's "logic of self-involvement". In conjoining these accounts, we wish to demonstrate how their combination sheds new light on understanding the phenomenon of prayer. Prayer is a complex phenomenon that involves two major dimensions: the private and the social, as Matthew (6: 6) and Acts (1: 14), respectively, demonstrate. Schutz's study of the phenomenon of "inner time" and the "polithetical" structure of consciousness, at both the subjective and intersubjective level, provides a useful lens to analyze these two dimensions. In addition, prayer, in following a specific set of rules, can also be considered as a specific, i.e., religious "language-game". In the last analysis, however, we propose to analyze prayer (and, finally, religion) within the Schutzian framework of "multiple realities," "enclaves," and "symbolic appresentation," which permits accessing the "religious finite province of meaning" in the very midst of the paramount reality of everyday life. In a nutshell, we claim that Christian prayer is a practice of constructing and living within a "religious province of meaning" in the everyday world; it is a practice that revolves around self-involving language-activities such as praising, confessing, thanksgiving, or requesting to God, which enable the praying subject to transfigure the language of everydayness and "see through" (Schutz) the world of everyday life in order to let it appear in a different light, e.g., the light of grace, gift, and salvation.

    Pain catastrophizing, appraisals of pain control, styles of coping, and social support have been suggested to affect functioning in patients with low back pain. We investigated the relation of chronic pain coping strategies to psychological variables and clinical data, in patients treated surgically due to lumbar disc herniation and coexisting spondylotic changes. The average age of study participants (n=90) was 43.47 years (SD 10.21). Patients completed the Polish versions of the Chronic Pain Coping Inventory-42 (PL-CPCI-42), Beck Depression Inventory (BDI-PL), Coping Strategies Questionnaire (CSQ-PL), Beliefs about Pain Control Questionnaire (BPCQ-PL), and Roland-Morris Disability Questionnaire (RMQ-PL). In the PL-CPCI-42 results, resting, guarding and coping self-statements were frequently used as coping strategies (3.96 SD 1.97; 3.72 SD 1.72; 3.47 SD 2.02, respectively). In the CSQ-PL domains, catastrophizing and praying/hoping were frequently used as coping strategies (3.62 SD 1.19). The mean score obtained from the BDI-PL was 11.86 SD 7.23, and 12.70 SD 5.49 from the RMDQ-PL. BPCQ-PL results indicate that the highest score was in the subscale measuring beliefs that powerful others can control pain (4.36 SD 0.97). Exercise correlated significantly with beliefs about internal control of pain (rs=0.22). We identified associations between radiating pain and guarding (p=0.038) and between sports recreation and guarding (p=0.013) and task persistence (p=0.041). Back pain characteristics, depressive mood, disability, and beliefs about personal control of pain are related to chronic LBP coping styles. Most of the variables related to advancement of degenerative changes were not associated with coping efforts.

  15. Antiabortion violence: causes and effects.

    Most antiabortion groups objected peacefully to the US Supreme Court decision granting women access to abortion by lobbying, demonstrating, and writing letters. Some groups reacted violently. In 1984, violent acts had climbed to 18 bombings and 6 acts of arson directed against abortion providers. They dropped in 1988-1990 and rose again in 1992-1993. The far rights' disapproval of the Reagan and Bush Administrations' inability to make abortion illegal accounts for these increased acts of violence. The violent antiabortion groups interpreted Reagan's failure to stop the continuing violence as approval of their methods. A former Catholic seminarian, Joseph Scheidler, called for a militant effort to end abortion, thereby unleashing the militant, violent antiabortion movement. He led local grassroots groups nationwide to accomplish the Year of Pain and Fear he called for in his book. Antiabortion zealots understand and use the potency of language. The dehumanize abortion providers. They suggest that followers pray for death or destruction. Their rhetoric of hatred motivates persons to perform violent acts. Little difference exists between clinic blockaders and clinic bombers/arsonists. Antiabortion zealots tend to be financial and social drifters escaping a past of drinking or drugs and from very dysfunctional families. Antiabortion violence has ushered in a new wave--murder of a provider. Abortion providers have adapted to lie with threats, jeering, and bricks thrown through windows. Even though abortion seekers fear personal injury, they fear even more harassment and invasion of privacy. Their tactics have reduced women's access to abortion care. Abortion providers operate in just 17% of US counties. When zealots spew hatred on families, however, providers often stop performing abortions. Nevertheless, communities are starting to stand up to the reactionaries. Neighbors, patients, businesses, and other physicians in Montana supported a clinic after a violent act

    This study was performed to analyze the friability, hardness and fiber content of fiber enriched milk tablet derived from five different local fiber sources such as carrot, spinach, dragon fruit, mango and watermelon. Cow milk was mixed to complement with the tablet as a protein source. The powder were spray dried at 100°C, 120°C and 140°C and freeze dried at -60°C. The mixture of fruits and milk were made into equal ratio with the addition of 15 maltodextrin as a carrier. Tablets formed were used for friability and hardness test while dried powder were used for fiber content analysis. Dragon fruit tablet dried at 140°C have the highest friability with 11. 42 of weight loss. The second highest friability was spinach tablet dried at 100°C and 120°C drying temp erature with 9.30 and 9.28 respectively. The lowest friability was exhibited by carrot, mango and watermelon tablet at 100°C and dragon fruit at 120°C while carrot and spinach at 140°C. In contras t, none of the freeze dried tablets showed any weight loss hence they are not friable. For hardness test, all of the freeze dried showed to have higher tensile strength than spray dried, where carrot showed to be the highest at 2.27 Newton and the lowest were spray dried mango at 0.16 Newton. In fiber content analysis, freeze dried mango have the highest fiber content followed by freeze dried carrot and 140°C s pray dried carrot. It can be concluded that the higher the spray dry temperature, the more friable is the tablet. While, high friability leads to lower hardness of tablets. In terms of fiber content, the higher the spray dry temperature, the lower the fiber content found.

    Valuation of features of habitats and ecosystems usually encompasses the goods and services that ecosystems provide, but rarely also examine how people value ecological resources in terms of eco-cultural and sacred activities. The social, sacred, and cultural aspects of ecosystems are particularly important to Native Americans, but western science has rarely examined the importance of eco-cultural attributes quantitatively. In this paper I explore differences in ecosystem evaluations, and compare the perceptions and evaluations of places people go for consumptive and non-consumptive resource use with evaluations of the same qualities for religious and sacred places. Qualities of ecosystems included goods (abundant fish and crabs, butterflies and flowers, clean water), services (complexity of nature, lack of radionuclides that present a health risk), and eco-cultural attributes (appears unspoiled, scenic horizons, noise-free). Native Americans and Caucasians were interviewed at a Pow Wow at Post Falls, Idaho, which is in the region with the Department of Energy’s Hanford Site, known for its storage of radioactive wastes and contamination. A higher percentage of Native American subjects engaged in consumptive and religious activities than did Caucasians. Native Americans engaged in higher rates of many activities than did Caucasians, including commune with nature, pray or meditate, fish or hunt, collect herbs, and conduct vision quests or other ceremonies. For nearly all attributes, there was no difference in the relative ratings given by Native Americans for characteristics of sites used for consumption/non-consumptive activities compared to religious/sacred places. However, Caucasians rated nearly all attributes lower for religious/sacred places than they did for places where they engaged in consumptive or non-consumptive activities.

    Ground water is one of Utah’s most extensive and valuable natural resources. Because of its widespread occurrence in both wet and dry areas, ground water has been, and is a major factor affecting economic growth and development of the State. In some areas, ground water is used to supplement streamflow for irrigation, public supply, and other uses. In other areas, it is the only water available for use. Many communities obtain their entire water supply from ground-water sources (wells and springs) as do numerous rural and suburban households throughout the State.The ground-water reservoirs of Utah contain tremendous quantities of water – many times more than the quantity stored in all the lakes (including Great Salt Lake) and the surface-water reservoirs of the State combined. Water that discharges from those underground reservoirs in seeps and springs is vital in sustaining the flow of streams during dry summer months and in providing the water needed to maintain important wetland habitats. Those same underground reservoirs also provide large quantities of water in carryover storage for use during prolonged droughts.The U.S. Geological survey, under cooperative programs with the Utah department of Natural resources and other Federal, State, and local agencies has been studying Utah’s ground-water resources since 1897. Much information has been gained during those studies about the occurrence, availability, and quality of ground water; the withdrawal and use of the water; and the effects of withdrawal. This report summarizes that information in nontechnical language, which is designed for all readers. Readers interested in more detailed information about ground water in specific areas of Utah are referred to the reports listed by LaPray and Hamblin (1980).

    To assess how people living with HIV and AIDS reacted to the knowledge of the infection and how they are coping with stigma and discrimination. The study was conducted in the two high density urban suburbs of Mabvuku and Tafara in Harare, Zimbabwe. The study was a descriptive cross sectional survey. A total of 600 participants (160 men and 440 women) who had received their HIV results after Voluntary Counselling and Testing for HIV at the Zimbabwe AIDS Prevention and Support Organization (ZAPSO) Mabvuku/Tafara Voluntary Counselling and Testing Centre were interviewed. Reactions to the diagnosis of HIV, disclosure of sero-status, experiences of self, family and community induced stigma and discrimination, coping mechanisms and desired interventions to reduce stigma. The majority, 61.7%, had been diagnosed HIV positive less than two years at the time of the study. While 33.3% felt hurt, 41% were immediately depressed when they discovered they were HIV positive. Eighty five percent had not disclosed their sero-status to anyone. While 55% experience self induced stigma, 56.7% experienced family induced and 38.3% experienced community induced stigma. People living with HIV and AIDS were coping with stigma through withdrawal (60%); joining support groups (83.3%); seeking counselling (95%) and praying (86.7%). Encouraging community counselling and HIV testing with disclosure of status was perceived by 98.3% of the respondents as an effective method to reduce HIV and AIDS related stigma and discrimination. While non disclosure of sero status is still high, self, family and community induced stigma pose a big challenge. Withdrawal (used mostly by men), seeking counselling and joining support groups (used mostly by older women) are the common coping behaviours being used by HIV positive clients. There is need to improve counselling capacities so as to meet the demands from a stigma reduction perspective as well as from a coping perspective.

    to investigate religiosity and spirituality as a resilience strategy for the long-living older adults in their daily lives. Qualitative research of phenomenological approach based on Martin Heidegger thoughts. Interviews were conducted with 14 older adults registered at a family health unit in the city of Jequié, BA, Brazil. The data were analyzed in the light of Being and Time. The results revealed that God occupies a central position in their lives, and the reading of the bible, praying the rosary and prayers are resilience strategies used for coping with unfavorable situations, recovery and/or maintenance of health, personal and family protection, and, above all, the experience of a satisfactory aging. Religiosity and spirituality were presented as an important resilience strategy in the existence of older adults, showing that through them it is possible to achieve well-being and cope with health and social problems.

    To examine the attitudes to and knowledge and beliefs about homosexuality of nurses and allied professionals in two early parenting services in Australia. Early parenting services employ nurses and allied professionals. Access and inclusion policies are important in community health and early childhood service settings. However, little is known about the perceptions of professionals who work within early parenting services in relation to lesbian, gay, bisexual and transgender families. This is the final in a series of studies and was undertaken in two early parenting services in two states in Australia using a cross-sectional design with quantitative and qualitative approaches. Validated questionnaires were completed by 51 nurses and allied professionals and tested with chi-squared test of independence (or Fisher's exact test), Mann-Whitney U-test, Kruskal-Wallis one-way analysis of variance or Spearman's rank correlation. Thematic analysis examined qualitative data collected in a box for free comments. Of the constructs measured by the questionnaires, no significant relationships were found in knowledge, attitude and gay affirmative practice scores by sociodemographic variables or professional group. However, attitude scores towards lesbians and gay men were significantly negatively affected by conservative political affiliation (p = 0·038), held religious beliefs (p = 0·011) and frequency of praying (p = 0·018). Six overall themes were found as follows: respect, parenting role, implications for the child, management, disclosure, resources and training. The study provided an in-depth analysis of the attitudes, knowledge and beliefs of professionals in two early parenting services, showing that work is needed to promote acceptance of diversity and the inclusion of lesbian, gay, bisexual and transgender families in planning, developing, evaluating and accessing early parenting services.

    The concern for fertility control is not alien to the cultural and religious heritage of Egypt. Historically, Egyptian interest in fertility dates to the Pharoahs. Contraceptive recipes written at least 15-18 centuries B.C. have been found. Romans may have borrowed some of the more effective methods from Egypt when it became part of the Roman Empire as evidenced by the decline in size of aristocratic Roman families at the beginning of the Christian era. Muslim conquerors of Egypt encouraged fertility control. In the 9th century differences of opinion about the legality of contraception appeared among the interpreters of Islamic law. Some methods found in the writings of Muslim doctors as al-Razi and Avicenna still survive in the folk medicine of Egypt. In modern times use of barrier methods of contraception were encouraged by family planning organizations in Egypt. The medical profession was not deeply involved since these methods did not require much medical assistance. In 1936 a religiouss verdict declared contraception to be a lawful act of Islam. National programs in family planning in the 1960's encouraged the use of the Lippes Loop IUD. The medical problem of blood loss associated with the IUD caused anxiety because of the high incidence of anemia in the female Egyptian population. There was also a cultural limitation on the wide use of the IUD. "Spotting" due to the IUD resulted in females being ritually unclean and therefore unfit to pray or observe the Islamic fast. The Pill, initially favored caused complications due to its effect on breast milk which is the universal source of nutrition for infants in Egypt. Replacement of the Pill by depo-provera injections during the post partum period of lactation is a practical solution. Permanent sterilization is limited to females and only performed when medically indicated. Abortion is illegal and permitted only as a therapeutic measure.

    By organizing and activating our passions with both hormones and experiences, the heart and mind of sexual behavior, sexual motivation, and sexual preference is the brain, the organ of learning. Despite decades of progress, this incontrovertible truth is somehow lost in the far-too-often biologically deterministic interpretation of genetic, hormonal, and anatomical scientific research into the biological origins of sexual motivation. Simplistic and polarized arguments are used in the media by both sides of the seemingly endless debate over sexual orientation, equality, and human rights with such catch phrases as 'born gay' contrasted against attempts of "reparative therapy" or "pray the gay away". Though long abandoned in practically every other area of psychology, this remnant of the nature-nurture controversy remains despite its generally acknowledged insufficiency in explaining any adult aspect of the human condition within the scientific community. THIS THEORETICAL REVIEW ARTICLE IDENTIFIES THREE FACTORS: 1) good intentions with regard to the argument from immutability; 2) false dichotomies limiting intellectual progress by oversimplification of theory and thus hypothesis, and most dangerously, interpretation and; 3) Tradition: a historical separation of the disciplines of biology and psychology, which, to this day, interferes with the effective translation of well-conducted science into good public understanding and policy. Studies clearly demonstrate that progress toward sexual-orientation equality is being made, if slowly, despite the apparent irrelevance of the "born gay" argument from immutability. Evidence is further provided supporting the inadequacy of polarized, dichotic theories of sexual development, particularly those pitting "blank slate learning" against a fated, deterministic biological perspective. Results of this review suggest that an emerging interactionist perspective will promote both better scientific progress and better public

    Synchronized behavior (chanting, singing, praying, dancing) is found in all human cultures and is central to religious, military, and political activities, which require people to act collaboratively and cohesively; however, we know little about the neural underpinnings of many kinds of synchronous behavior (e.g., vocal behavior) or its role in establishing and maintaining group cohesion. In the present study, we measured neural activity using fMRI while participants spoke simultaneously with another person. We manipulated whether the couple spoke the same sentence (allowing synchrony) or different sentences (preventing synchrony), and also whether the voice the participant heard was “live” (allowing rich reciprocal interaction) or prerecorded (with no such mutual influence). Synchronous speech was associated with increased activity in posterior and anterior auditory fields. When, and only when, participants spoke with a partner who was both synchronous and “live,” we observed a lack of the suppression of auditory cortex, which is commonly seen as a neural correlate of speech production. Instead, auditory cortex responded as though it were processing another talker's speech. Our results suggest that detecting synchrony leads to a change in the perceptual consequences of one's own actions: they are processed as though they were other-, rather than self-produced. This may contribute to our understanding of synchronized behavior as a group-bonding tool. SIGNIFICANCE STATEMENT Synchronized human behavior, such as chanting, dancing, and singing, are cultural universals with functional significance: these activities increase group cohesion and cause participants to like each other and behave more prosocially toward each other. Here we use fMRI brain imaging to investigate the neural basis of one common form of cohesive synchronized behavior: joint speaking (e.g., the synchronous speech seen in chants, prayers, pledges). Results showed that joint speech recruits

    2013-01-01

    Background In regions where access to clean water and the provision of a sanitary infrastructure has not been sustainable, cholera continues to pose an important public health burden. Although oral cholera vaccines (OCV) are effective means to complement classical cholera control efforts, still relatively little is known about their acceptability in targeted communities. Clarification of vaccine acceptability prior to the introduction of a new vaccine provides important information for future policy and planning. Methods In a cross-sectional study in Katanga province, Democratic Republic of Congo (DRC), local perceptions of cholera and anticipated acceptance of an OCV were investigated. A random sample of 360 unaffected adults from a rural town and a remote fishing island was interviewed in 2010. In-depth interviews with a purposive sample of key informants and focus-group discussions provided contextual information. Socio-cultural determinants of anticipated OCV acceptance were assessed with logistic regression. Results Most respondents perceived contaminated water (63%) and food (61%) as main causes of cholera. Vaccines (28%), health education (18%) and the provision of clean water (15%) were considered the most effective measures of cholera control. Anticipated vaccine acceptance reached 97% if an OCV would be provided for free. Cholera-specific knowledge of hygiene and self-help in form of praying for healing were positively associated with anticipated OCV acceptance if costs of USD 5 were assumed. Conversely, respondents who feared negative social implications of cholera were less likely to anticipate acceptance of OCVs. These fears were especially prominent among respondents who generated their income through fishing. With an increase of assumed costs to USD 10.5, fear of financial constraints was negatively associated with anticipated vaccine acceptance as well. Conclusions Results suggest a high motivation to use an OCV as long as it seems affordable. The

    An adult female (22 years) of Christian orthodox religion was examined during the silent Lord's prayer, the most common, short prayer, with the aim of possible differentiation between belief and knowledge in her experience, analyzing the behavior of subgroups of theta and beta cerebral EEG rhythms, which occur through constant and occasional activation of cerebral regions. The participant was not trained in reading the prayer to herself or other people. EEG examination was performed by Nihon Kohden Corporation, EEG-1200-K Neurofax apparatus, in the monopolar longitudinal montage in the system of 10/20 electrodes aimed at determining the peak frequency value of each exploratory site. The method of result analysis was based on connecting cerebral regions into networks of 3 or more members according to identical peak frequency value, which was observed within subgroups of theta and beta frequencies and analyzed through a proximity index and continuity and discontinuity of activation during the observed period. Out of the definite observation sample of 3 s from each subperiods (beginning, middle and end), a window of 2 s was moving from the beginning till end of the period with 200-ms time lag. This resulted in six subsamples for each electrode and for each experimental situation (resting state, situation of prayer). Stable and unstable activity of the regions was assessed within subgroups via cartographic formulas equivalent to the states which subgroups of theta and beta imply in psychophysiological sense. The results indicated that through participant's inner dialogue-monologue there are elements of both knowledge and belief, and that this phenomenon is possible considering insufficiently specific circumstances of the experiment and the participant herself, such as her relatively young age and insufficient practice of praying. The paper discusses the types of connections between regions which imply knowledge and those related to belief according to our

    2014-01-01

    Background: During cardio-pulmonary resuscitation, family members, in some hospitals, are usually pushed to stay out of the resuscitation room. However, growing literature implies that family presence during resuscitation could be beneficial. Previous literature shows controversial belief whether or not a family member should be present during resuscitation of their relative. Some worldwide association such as the American Heart Association supports family-witnessed resuscitation and urge hospitals to develop policies to ease this process. The opinions on family-witnessed resuscitation vary widely among various cultures, and some hospitals are not applying such polices yet. This study explores family members’ needs during resuscitation in adult critical care settings. Methods: This is a part of larger study. The study was conducted in six hospitals in two major Jordanian cities. A purposive sample of seven family members, who had experience of having a resuscitated relative, was recruited over a period of six months. Semi-structured interview was utilised as the main data collection method in the study. Findings: The study findings revealed three main categories: families’ need for reassurance; families’ need for proximity; and families’ need for support. The need for information about patient’s condition was the most important need. Updating family members about patient’s condition would reduce their tension and improve their acceptance for the end result of resuscitation. All interviewed family members wanted the option to stay beside their loved one at end stage of their life. Distinctively, most of family members want this option for some religious and cultural reasons such as praying and supplicating to support their loved one. Conclusions: This study emphasizes the importance of considering the cultural and religious dimensions in any family-witnessed resuscitation programs. The study recommends that family members of resuscitated patients should

    Mothers' existential dimensions in the transition to motherhood have not been described thoroughly. They might experience disruption and new perspectives in existential ways and this may especially be the case in preterm birth. The aim of this study was twofold. First we investigated the existential dimension of motherhood transition in a secularized context, through practices of prayer and meditation. Second we described the relationship between time of birth (term/preterm) and the prayer/meditation practices of the mothers. Data were gathered from a nationwide questionnaire survey among first time mothers conducted during the summer 2011. All Danish women who gave birth before the 32(nd) pregnancy week (n = 255), and double the number of mothers who gave birth at full term (n = 658) in 2010 were included (total n = 913). The questionnaire consisted of 46 overall items categorized in seven sections, which independently cover important aspects of existential meaning-making related to becoming a mother. The respondent rate was 57% (n = 517). Moments of praying or meditation 6-18 months post partum were reported by 65%, and mothers who responded affirmatively, practiced prayer (n = 286) more than meditation (n = 89), p < 0,001. We did not observe differences in affirmative responses to prayer or meditation between mothers of full term or preterm born children, not even after controlling for perinatal or post partum loss, mode of birth, age, status of cohabiting or education. In this explorative study we found specific practices of existential meaning-making through prayer and/or meditation among first time mothers, living in a very secularized context. Yet we know only little about character or importance of these practices among mothers, and hardly anything about existential meaning-making among new fathers. Hence the implications of meaning-making practices related to other dimensions of health are difficult to address in a qualified way

    Background The role of religious beliefs in the prevention of HIV and attitudes towards the infected has received considerable attention. However, little research has been conducted on Faith Leaders' (FLs) perceptions of antiretroviral therapy (ART) in the developing world. This study investigated FLs' attitudes towards different HIV treatment options (traditional, medical and spiritual) available in a rural Tanzanian ward. Methods Qualitative interviews were conducted with 25 FLs purposively selected to account for all the denominations present in the area. Data was organised into themes using the software package NVIVO-7. The field work guidelines were tailored as new topics emerged and additional codes progressively added to the coding frame. Results Traditional healers (THs) and FLs were often reported as antagonists but duality prevailed and many FLs simultaneously believed in traditional healing. Inter-denomination mobility was high and guided by pragmatism. Praying for the sick was a common practice and over one third of respondents said that prayer could cure HIV. Being HIV-positive was often seen as "a punishment from God" and a consequence of sin. As sinning could result from "the work of Satan", forgiveness was possible, and a "reconciliation with God" deemed as essential for a favourable remission of the disease. Several FLs believed that "evil spirits" inflicted through witchcraft could cause the disease and claimed that they could cast "demons" away. While prayers could potentially cure HIV "completely", ART use was generally not discouraged because God had "only a part to play". The perceived potential superiority of spiritual options could however lead some users to interrupt treatment. Conclusions The roll-out of ART is taking place in a context in which the new drugs are competing with a diversity of existing options. As long as the complementarities of prayers and ART are not clearly and explicitly stated by FLs, spiritual options may be

    Valuation of features of habitats and ecosystems usually encompasses the goods and services that ecosystems provide, but rarely also examine how people value ecological resources in terms of eco-cultural and sacred activities. The social, sacred, and cultural aspects of ecosystems are particularly important to Native Americans, but western science has rarely examined the importance of eco-cultural attributes quantitatively. In this paper I explore differences in ecosystem evaluations, and compare the perceptions and evaluations of places people go for consumptive and non-consumptive resource use with evaluations of the same qualities for religious and sacred places. Qualities of ecosystems included goods (abundantmore » fish and crabs, butterflies and flowers, clean water), services (complexity of nature, lack of radionuclides that present a health risk), and eco-cultural attributes (appears unspoiled, scenic horizons, noise-free). Native Americans and Caucasians were interviewed at a Pow Wow at Post Falls, Idaho, which is in the region with the Department of Energy's Hanford Site, known for its storage of radioactive wastes and contamination. A higher percentage of Native American subjects engaged in consumptive and religious activities than did Caucasians. Native Americans engaged in higher rates of many activities than did Caucasians, including commune with nature, pray or meditate, fish or hunt, collect herbs, and conduct vision quests or other ceremonies. For nearly all attributes, there was no difference in the relative ratings given by Native Americans for characteristics of sites used for consumption/non-consumptive activities compared to religious/sacred places. However, Caucasians rated nearly all attributes lower for religious/sacred places than they did for places where they engaged in consumptive or non-consumptive activities. Native Americans were less concerned with distance from home for consumptive/non-consumptive activities, compared to

    Background By organizing and activating our passions with both hormones and experiences, the heart and mind of sexual behavior, sexual motivation, and sexual preference is the brain, the organ of learning. Despite decades of progress, this incontrovertible truth is somehow lost in the far-too-often biologically deterministic interpretation of genetic, hormonal, and anatomical scientific research into the biological origins of sexual motivation. Simplistic and polarized arguments are used in the media by both sides of the seemingly endless debate over sexual orientation, equality, and human rights with such catch phrases as ‘born gay’ contrasted against attempts of “reparative therapy” or “pray the gay away”. Though long abandoned in practically every other area of psychology, this remnant of the nature-nurture controversy remains despite its generally acknowledged insufficiency in explaining any adult aspect of the human condition within the scientific community. Methods This theoretical review article identifies three factors: 1) good intentions with regard to the argument from immutability; 2) false dichotomies limiting intellectual progress by oversimplification of theory and thus hypothesis, and most dangerously, interpretation and; 3) Tradition: a historical separation of the disciplines of biology and psychology, which, to this day, interferes with the effective translation of well-conducted science into good public understanding and policy. Results Studies clearly demonstrate that progress toward sexual-orientation equality is being made, if slowly, despite the apparent irrelevance of the “born gay” argument from immutability. Evidence is further provided supporting the inadequacy of polarized, dichotic theories of sexual development, particularly those pitting “blank slate learning” against a fated, deterministic biological perspective. Results of this review suggest that an emerging interactionist perspective will promote both better

    Chanting and praying are among the most popular religious activities, which are said to be able to alleviate people’s negative emotions. However, the neural mechanisms underlying this mental exercise and its temporal course have hardly been investigated. Here, we used event-related potentials (ERPs) to explore the effects of chanting the name of a Buddha (Amitābha) on the brain’s response to viewing negative pictures that were fear- and stress-provoking. We recorded and analyzed electroencephalography (EEG) data from 21 Buddhists with chanting experience as they viewed negative and neutral pictures. Participants were instructed to chant the names of Amitābha or Santa Claus silently to themselves or simply remain silent (no-chanting condition) during picture viewing. To measure the physiological changes corresponding to negative emotions, electrocardiogram and galvanic skin response data were also collected. Results showed that viewing negative pictures (vs. neutral pictures) increased the amplitude of the N1 component in all the chanting conditions. The amplitude of late positive potential (LPP) also increased when the negative pictures were viewed under the no-chanting and the Santa Claus condition. However, increased LPP was not observed when chanting Amitābha. The ERP source analysis confirmed this finding and showed that increased LPP mainly originated from the central-parietal regions of the brain. In addition, the participants’ heart rates decreased significantly when viewing negative pictures in the Santa Claus condition. The no-chanting condition had a similar decreasing trend although not significant. However, while chanting Amitābha and viewing negative pictures participants’ heart rate did not differ significantly from that observed during neutral picture viewing. It is possible that the chanting of Amitābha might have helped the participants to develop a religious schema and neutralized the effect of the negative stimuli. These findings

When feeling overwhelmed by their circumstances, the children self-withdrew and performed positive activities (e.g., praying, watching TV, listening to the radio, singing, dancing) to help themselves feel better. Many HIV-affected families have a combination of HIV-positive and negative siblings within the household. Pending further studies conducted with larger sample sizes, the results of this study should assist healthcare professionals to better facilitate disclosure between HIV-positive parents and their children of mixed HIV statuses.

    The purpose of this study was to examine the frequency of complementary and alternative medicine usage in asthmatic patients living in the west of Turkey, the most frequently used complementary and alternative medicine methods and socio-demographic factors affecting this and factors related to the disease. While the rate of complementary and alternative medicine usage in asthmatic patients and the reasons for using it vary, practices specific to different countries and regions are of interest. Differing cultural and social factors even in geographically similar regions can affect the type of complementary and alternative medicine used. Two hundred asthmatic patients registered in the asthma outpatient clinic of a large hospital in Turkey and who had undergone pulmonary function tests within the previous six months were included in this study, which was planned according to a descriptive design. The patients filled out a questionnaire on their demographic characteristics and complementary and alternative medicine usage. The proportion of patients who reported using one or more of the complementary and alternative medicine methods was 63·0%. Of these patients, 61·9% were using plants and herbal treatments, 53·2% were doing exercises and 36·5% said that they prayed. The objectives of their use of complementary and alternative medicine were to reduce asthma-related complaints (58%) and to feel better (37·8%). The proportion of people experiencing adverse effects was 3·3% (n = 4). Factors motivating asthmatic patients to use complementary and alternative medicine were the existence of comorbid diseases and a long period since diagnosis (p < 0·05). No statistically significant difference was found between the use of complementary and alternative medicine and the severity of the disease, pulmonary function test parameters, the number of asthma attacks or hospitalisations because of asthma within the last year (p > 0·05).

    To the authors' knowledge, there are few studies to date regarding colorectal cancer (CRC) beliefs, knowledge, and screening among multiple Asian American populations, who are reported to have lower CRC screening rates compared with white individuals. The current study was performed to assess knowledge and beliefs regarding the causes of CRC, its prevention, and factors associated with CRC screening among 3 Asian American groups. The authors conducted an in-language survey with Filipino (Honolulu, Hawaii), Hmong (Sacramento, California), and Korean (Los Angeles, California) Americans aged 50 to 75 years who were sampled through social networks. Bivariate and multivariable analyses were conducted to assess factors associated with CRC screening. The sample of 981 participants was 78.3% female and 73.8% r
