2010-01-01

This paper introduces a new Open Source Java library suited for the simulation of embedded control systems. The library is based on the ideas and architecture of TrueTime, a toolbox of Matlab devoted to this topic, and allows Java programmers to simulate the performance of control processes which run in a real time environment. Such simulations can improve considerably the learning and design of multitasking real-time systems. The choice of Java increases considerably the usability of our library, because many educators program already in this language. But also because the library can be easily used by Easy Java Simulations (EJS), a popular modeling and authoring tool that is increasingly used in the field of Control Education. EJS allows instructors, students, and researchers with less programming capabilities to create advanced interactive simulations in Java. The paper describes the ideas, implementation, and sample use of the new library both for pure Java programmers and for EJS users. The JTT library and some examples are online available on http://lab.dia.uned.es/jtt. PMID:22163674

The Psychological Benefits from Reconceptualizing Music-Making as Mindfulness Practice.

PubMed

Steinfeld, Matthew; Brewer, Judson

2015-06-01

While the music psychology and education literatures have devoted considerable attention to how musical instrumentalists practice their instruments, less formal scholarly attention has been given in consideration of what it means to maintain a musical "practice" over time and across context. In this paper, the practice of mindfulness meditation is used as heuristic, arguing for a view of mindfulness meditation as a formalized de-specialization of the infinite number of other activities with which people can achieve mindfulness. Sitting meditation, requiring of one to observe the contents of their mind unmediated, can serve as a useful model for the musician in understanding the phenomenology of the music-making process and the "flow" states that can result from an embodied musical practice. Finally, reconceptualizing music-making as a mindfulness practice is considered with psychological and pedagogical implications relevant for developing musicians.

A study of the relative effectiveness and cost of computerized information retrieval in the interactive mode

Smetana, F. O.; Furniss, M. A.; Potter, T. R.

1974-01-01

Results of a number of experiments to illuminate the relative effectiveness and costs of computerized information retrieval in the interactive mode are reported. It was found that for equal time spent in preparing the search strategy, the batch and interactive modes gave approximately equal recall and relevance. The interactive mode however encourages the searcher to devote more time to the task and therefore usually yields improved output. Engineering costs as a result are higher in this mode. Estimates of associated hardware costs also indicate that operation in this mode is more expensive. Skilled RECON users like the rapid feedback and additional features offered by this mode if they are not constrained by considerations of cost.

Multislice 1H magnetic resonance spectroscopic imaging: assessment of epilepsy, Alzheimer's disease, and amyotrophic lateral sclerosis

NASA Astrophysics Data System (ADS)

Weiner, Michael W.; Maudsley, Andrew A.; Schuff, Norbert; Soher, Brian J.; Vermathen, Peter P.; Fein, George; Laxer, Kenneth D.

1998-07-01

Proton magnetic resonance spectroscopic imaging (1H MRSI) with volume pre-selection (i.e. by PRESS) or multislice 1H MRSI was used to investigate changes in brain metabolites in Alzheimer's disease, epilepsy, and amyotrophic lateral sclerosis. Examples of results from several ongoing clinical studies are provided. Multislice 1H MRSI of the human brain, without volume pre-selection offers considerable advantages over previously available techniques. Furthermore, MRI tissue segmentation and completely automated spectra curve fitting greatly facilitate quantitative data analysis. Future efforts will be devoted to obtaining full brain coverage and data acquisition at short spin echo times (TE less than 30 ms) for the detection of metabolites with short T2 relaxation times.

Restricted Collision List method for faster Direct Simulation Monte-Carlo (DSMC) collisions

DOE Office of Scientific and Technical Information (OSTI.GOV)

Macrossan, Michael N., E-mail: m.macrossan@uq.edu.au

The ‘Restricted Collision List’ (RCL) method for speeding up the calculation of DSMC Variable Soft Sphere collisions, with Borgnakke–Larsen (BL) energy exchange, is presented. The method cuts down considerably on the number of random collision parameters which must be calculated (deflection and azimuthal angles, and the BL energy exchange factors). A relatively short list of these parameters is generated and the parameters required in any cell are selected from this list. The list is regenerated at intervals approximately equal to the smallest mean collision time in the flow, and the chance of any particle re-using the same collision parameters inmore » two successive collisions is negligible. The results using this method are indistinguishable from those obtained with standard DSMC. The CPU time saving depends on how much of a DSMC calculation is devoted to collisions and how much is devoted to other tasks, such as moving particles and calculating particle interactions with flow boundaries. For 1-dimensional calculations of flow in a tube, the new method saves 20% of the CPU time per collision for VSS scattering with no energy exchange. With RCL applied to rotational energy exchange, the CPU saving can be greater; for small values of the rotational collision number, for which most collisions involve some rotational energy exchange, the CPU may be reduced by 50% or more.« less

The problem of education of culture of health in children ofpreschool age is actual and sufficiently complicated. It is important at this age stage to create in children the first knowledge and practical skills of a healthy lifestyle. The example of parents has considerable impact on adoption of health saving behavior of a child. For identification of motivations of parents in the sphere of protection and strengthening of health of their children there was performed questionnaire survey of parents of preschool children according to specially developed questionnaire. A half of parents are established to be unable to devote sufficient time to health of the child due to engrossment. A considerable portion of parents doesn't keep a healthy lifestyle, differs in low medical and sports activity. The main motivation of parents is the motivation on recovery of the child after the disease, but not on preservation, strengthening and development of health.

Placebo Mechanisms of Manual Therapy: A Sheep in Wolf's Clothing?

When a physical therapist provides a manual therapy (MT) intervention for a patient presenting with pain and the patient experiences a positive clinical outcome, we cannot answer as to why this occurs. Would we continue to devote valuable time and financial resources to learning and improving our skills in providing MT interventions if the related clinical outcomes were placebo responses? In this Viewpoint, the authors conceptualize placebo as an active and important mechanism of MT and argue that placebo mechanisms deserve consideration as an important component of the treatment effect.

Everyday Strivings in War Veterans With Posttraumatic Stress Disorder: Suffering From a Hyper-Focus on Avoidance and Emotion Regulation

PubMed Central

Kashdan, Todd B.; Breen, William E.; Julian, Terri

2014-01-01

This research investigated whether combat veterans' daily strivings are related to the presence of post-traumatic stress disorder (PTSD) and well-being. Veterans created a list of their most important strivings, which were content-analyzed for emotion regulation and approach or avoidance themes. It was hypothesized that veterans pursuing strivings with themes of emotion regulation or avoidance experience deleterious consequences compared with other veterans. For all veterans, devoting finite time and energy in daily life to regulating emotions was associated with less purpose, meaning, and joy compared with other strivings. Veterans with PTSD endorsed more strivings related to emotion regulation and devoted considerable effort to emotion regulation and avoidance strivings. Yet, these efforts failed to translate into any discernible benefits; veterans without PTSD derived greater joy and meaning from strivings focusing on approac- oriented behavior and themes other than emotion regulation. The presence of PTSD and a high rate of emotion regulation strivings led to the lowest global well-being and daily self-esteem during a 14-day assessment period. The presence of PTSD and a high rate of avoidance strivings also led to lower emotional well-being. Results indicate that strivings devoted to regulating emotions or avoidance efforts influence the mental health of veterans with and without PTSD. Studying personality at different levels of analysis—traits, strivings, and life narratives—allows for a fine-grained understanding of emotional disorders. PMID:20569784

Beyond telecommuting

Loken, S.C.; Niles, J.

1996-05-01

Although there has been considerable discussion about how telecommunications will affect the demand for transportation, most studies have focused on substituting telecommunications for transportation. For example, telephone and video conferencing can replace travel for meetings; electronic mail can replace postal service. More importantly, people can telecommute part-time or full- time using telecommunications instead of traveling to work. There are many other examples of reducing or eliminating travel by telecommunicating, but what may not be obvious is how telecommunications stimulates travel. As the volume of telecommunications traffic increases, travel has been stimulated in a number of important ways. Increased telecommunications hasmore » fostered economic growth that has, in turn, increased travel. With increased use of telecommunications, people move farther apart so economic and social trips become, on the average, longer. to ensure that society continues to benefit from this stimulation, the government will have to devote considerable attention to developing the telecommunications infrastructure and to supporting appropriate telecommunications policy. In particular, governments must learn to allocate resources and attention reasonably to ensure that systems support economic and social growth.« less

1991-02-01

Laughing gulls ( Larus atricilla) forage on horseshoe crab ( Limulus polyphemus) eggs during May in Delaware Bay each year. They feed in dense flocks, and foraging rates vary with vigilance, bird density, number of steps and location in the flock, whereas time devoted to vigilance is explained by number of steps, density, location and feeding rates. The time devoted to vigilance decreases with increasing density, increasing foraging rates and decreasing aggression. Birds foraging on the edge of flocks take fewer pecks and more steps, and devote more time to vigilance than those in the intermediate or central parts of a flock.

Future so bright? Delay discounting and consideration of future consequences predict academic performance among college drinkers.

PubMed

2017-10-01

College student drinking is a major public health concern and can result in a range of negative consequences, from acute health risks to decreased academic performance and drop out. Harm reduction interventions have been developed to reduce problems associated with drinking but there is a need to identify specific risk/protective factors related to academic performance among college drinkers. Behavioral economics suggests that chronic alcohol misuse reflects a dysregulated behavioral process or reinforcer pathology-alcohol is overvalued and the value of prosocial rewards are sharply discounted due, in part, to their delay. This study examined delay discounting, consideration of future consequences (CFC) and protective behavioral strategies (PBS) as predictors of academic success (grade point average; GPA) and engagement (time devoted to academic activities) among 393 college drinkers (61% female). In multivariate models, PBS were associated with greater academic engagement, but were not with academic success. Lower discounting of delayed rewards and greater CFC were associated with both academic success and engagement among drinkers. Previous research suggests that future time orientation is malleable, and the current results provide support for efforts to enhance future time orientation as part of alcohol harm-reduction approaches.

Use of the superpopulation approach to estimate breeding population size: An example in asynchronously breeding birds

USGS Publications Warehouse

Williams, K.A.; Frederick, P.C.; Nichols, J.D.

2011-01-01

Many populations of animals are fluid in both space and time, making estimation of numbers difficult. Much attention has been devoted to estimation of bias in detection of animals that are present at the time of survey. However, an equally important problem is estimation of population size when all animals are not present on all survey occasions. Here, we showcase use of the superpopulation approach to capture-recapture modeling for estimating populations where group membership is asynchronous, and where considerable overlap in group membership among sampling occasions may occur. We estimate total population size of long-legged wading bird (Great Egret and White Ibis) breeding colonies from aerial observations of individually identifiable nests at various times in the nesting season. Initiation and termination of nests were analogous to entry and departure from a population. Estimates using the superpopulation approach were 47-382% larger than peak aerial counts of the same colonies. Our results indicate that the use of the superpopulation approach to model nesting asynchrony provides a considerably less biased and more efficient estimate of nesting activity than traditional methods. We suggest that this approach may also be used to derive population estimates in a variety of situations where group membership is fluid. ?? 2011 by the Ecological Society of America.

Because of the bioterrorism threat posed by agents such as variola virus, considerable time, resources, and effort have been devoted to biodefense preparation. One avenue of this research has been the development of rapid, sensitive, high-throughput assays to validate immune responses to poxviruses. Here we describe the adaptation of a β-galactosidase reporter-based vaccinia virus neutralization assay to large-scale use in a study that included over 1,000 subjects. We also describe the statistical methods involved in analyzing the large quantity of data generated. The assay and its associated methods should prove useful tools in monitoring immune responses to next-generation smallpox vaccines, studying poxvirus immunity, and evaluating therapeutic agents such as vaccinia virus immune globulin.

In the present study the estimation of the heave and pitch motion of a ship is considered, using Kalman filtering techniques. A significant part of the study is devoted to constructing appropriate models for the sea and the ship. The governing equations are obtained from hydrodynamic considerations in the form of linear differential equations with frequency dependent coefficients. In addition, nonminimum phase characteristics are obtained due to the spatial integration of the water wave forces. The resulting transfer matrix function is irrational and nonminimum phase. The conditions for a finite-dimensional approximation are considered and the impact of the various parameters is assessed. A numerical application is considered for a DD-963 destroyer.

During this reporting period, five papers appeared in refereed journals for which I was either author or co-author, and two additional papers have recently been submitted to ApJ. Also, three conference proceedings papers were submitted. These publications are listed in the attached bibliography.

Work hard, play hard?: A comparison of male and female lawyers' time in paid and unpaid work and participation in leisure activities.

PubMed

Wallace, Jean E; Young, Marisa C

2010-02-01

There has been a considerable amount of research that documents how women and men spend their time in different work and home tasks. We examine how much time professional women and men spend in paid and unpaid work and how this relates to their participation in different leisure activities. We also explore whether time in paid and unpaid work has gender-specific effects on leisure participation. In examining these issues, we rely on data from lawyers working in different legal settings. Our results show that, as hypothesized, men report more time in paid work and leisure whereas women devote more time to housework and childcare. An unexpected finding is that the time men spend in housework or childcare is either unrelated or positively related to their leisure participation. These results suggest that men's greater overall opportunities for leisure compared with women's appear to stem from the unanticipated relationships between men's involvement in housework and childcare and their leisure activities. We raise several possible explanations for these findings.

Design considerations of manipulator and feel system characteristics in roll tracking

NASA Technical Reports Server (NTRS)

Johnston, Donald E.; Aponso, Bimal L.

1988-01-01

A fixed-base simulation was performed to identify and quantify interactions between the pilot's hand/arm neuromuscular subsystem and such control system features of typical modern fighter aircraft roll rate command mechanizations as: (1) force versus displacement sensing side-stick type manipulator, (2) feel force/displacement gradient, (3) feel system versus command prefilter dynamic lag, and (4) flight control system effective time delay. The experiment encompassed some 48 manipulator/filter/aircraft configurations. Displacement side-stick experiment results are given and compared with the previous force sidestick experiment results. Attention is focused on control bandwidth, excitement (peaking) of the neuromuscular mode, feel force/displacement gradient effects, time delay effects, etc. Section 5 is devoted to experiments with a center-stick in which force versus displacement sensing, feel system lag, and command prefilter lag influences on tracking performance and pilot preference are investigated.

Improvement of Clinical Skills through Pharmaceutical Education and Clinical Research.

PubMed

Ishizaki, Junko

2017-01-01

Professors and teaching staff in the field of pharmaceutical sciences should devote themselves to staying abreast of relevant education and research. Similarly those in clinical pharmacies should contribute to the advancement of pharmaceutical research and the development of next generation pharmacists and pharmaceuticals. It is thought that those who work in clinical pharmacies should improve their own skills and expertise in problem-finding and -solving, i.e., "clinical skills". They should be keen to learn new standard treatments based on the latest drug information, and should try to be in a position where collecting clinical information is readily possible. In the case of pharmacists in hospitals and pharmacies, they are able to aim at improving their clinical skills simply through performing their pharmaceutical duties. On the other hand, when a pharmaceutical educator aims to improve clinical skills at a level comparable to those of clinical pharmacists, it is necessary to devote or set aside considerable time for pharmacist duties, in addition to teaching, which may result in a shortage of time for hands-on clinical practice and/or in a decline in the quality of education and research. This could be a nightmare for teaching staff in clinical pharmacy who aim to take part in such activities. Nonetheless, I believe that teaching staff in the clinical pharmacy area could improve his/her clinical skills through actively engaging in education and research. In this review, I would like to introduce topics on such possibilities from my own experiences.

Perspective of the Graduating Medical Student: The Ideal Curriculum for the Fourth Year of Undergraduate Medical Education.

Andrews, Mary A; Paolino, Nathalie D; DeZee, Kent J; Hemann, Brian

2016-11-01

To explore medical students' perspective regarding the fourth year of medical school and common educational activities thereof. The authors surveyed students graduating in 2012 with a military service obligation about the importance of common fourth-year activities, the proportion of the fourth year devoted to these activities, and important considerations for the fourth-year curriculum. The authors calculated mean importance scores for educational activities and mean proportions of the fourth year that should be devoted to certain activities. Two reviewers independently coded free-text answers to identify and calculate frequencies for common themes. The response rate was 40% (376/942). Participants rated activities related to improving clinical skills and securing the residency of their choice as more than activities such as learning business skills, conducting research, and studying basic sciences. Participants indicated that electives and direct patient care should comprise the majority of the fourth year and frequently mentioned improving specialty-specific clinical skills, pursuing personal medical interests, and taking time to relax as important fourth-year themes. Students value activities related to securing and succeeding in their chosen residency and the opportunity to pursue electives and take vacation. Faculty should consider the student perspective when reforming curricula. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

The value of the time which people devote to each activity of their lives is compared with the money they spend on the activity. After tax wage rates are used to value an individual's time. The enormous size of the household economy and the fact that for most activities the value of the consumer's time devoted to an activity exceeds the money expenditures on the activity, suggest that there are many opportunities for productivity improvements in the household economy which have been overlooked in most traditional thinking on productivity.

The technological advances most likely to contribute to advanced aircraft designs and the efficiency, performance, and financial considerations driving the development directions for new aircraft are reviewed. Fuel-efficiency is perceived as the most critical factor for any new aircraft or component design, with most gains expected to come in areas of propulsion, aerodynamics, configurations, structural designs and materials, active controls, digital avionics, laminar flow control, and air-traffic control improvements. Any component area offers an efficiency improvement of 3-12%, with a maximum of 50% possible with a 4000 m range aircraft. Advanced turboprops have potential applications in short and medium haul subsonic aircraft, while a fuel efficient SST may be possible by the year 2000. Further discussion is devoted to the pivoted oblique wing aircraft, lightweight structures, and the necessity for short payback times.

2018-04-01

Deep learning techniques have recently emerged as promising decision supporting approaches to automatically analyze medical images for different clinical diagnosing purposes. Diagnosing of pulmonary nodules by using computer-assisted diagnosing has received considerable theoretical, computational, and empirical research work, and considerable methods have been developed for detection and classification of pulmonary nodules on different formats of images including chest radiographs, computed tomography (CT), and positron emission tomography in the past five decades. The recent remarkable and significant progress in deep learning for pulmonary nodules achieved in both academia and the industry has demonstrated that deep learning techniques seem to be promising alternative decision support schemes to effectively tackle the central issues in pulmonary nodules diagnosing, including feature extraction, nodule detection, false-positive reduction, and benign-malignant classification for the huge volume of chest scan data. The main goal of this investigation is to provide a comprehensive state-of-the-art review of the deep learning aided decision support for pulmonary nodules diagnosing. As far as the authors know, this is the first time that a review is devoted exclusively to deep learning techniques for pulmonary nodules diagnosing.

Various aspects of physical activity among Lithuanian adolescents.

Bergier, Barbara; Bergier, Józef; Wojtyła, Andrzej

2012-01-01

Studies of the physical activity of 17-year-old adolescents attending selected schools in Lithuania were conducted in 2010 with the use of the IPAQ. The adolescents differed with respect to the scope of leisure time possessed. Considerably more boys than girls indicated that they had a sufficient amount of leisure time, but to the contrary, considerably more girls than boys declared that they possessed an insufficient amount of free time. The majority of schoolchildren were characterized by a high level of physical activity, with the larger group being boys. Low activity was not observed among boys, and in only a few girls. Moderate effort constituted the highest percentage of physical activity among adolescents, whereas an intensive activity - the lowest. Considering the total area of activity, there dominated occupational activity (education), while its smallest percentage was devoted to sports and recreation. Boys evaluated their physical efficacy in more negative terms than girls. Adolescents with a higher self-reported efficacy were characterized by higher physical activity. The majority of adolescents had a normal BMI. Girls and boys had different preferences concerning motor activities. Girls mainly used walks, bicycle riding, and running, while boys also chose bicycle riding and running, and played sports games. The adolescents also had new expectations - girls reported mainly horse riding, aerobics and dancing, whereas boys mentioned football and bodybuilding fitness exercises.

Group implicit concurrent algorithms in nonlinear structural dynamics

NASA Technical Reports Server (NTRS)

Ortiz, M.; Sotelino, E. D.

1989-01-01

During the 70's and 80's, considerable effort was devoted to developing efficient and reliable time stepping procedures for transient structural analysis. Mathematically, the equations governing this type of problems are generally stiff, i.e., they exhibit a wide spectrum in the linear range. The algorithms best suited to this type of applications are those which accurately integrate the low frequency content of the response without necessitating the resolution of the high frequency modes. This means that the algorithms must be unconditionally stable, which in turn rules out explicit integration. The most exciting possibility in the algorithms development area in recent years has been the advent of parallel computers with multiprocessing capabilities. So, this work is mainly concerned with the development of parallel algorithms in the area of structural dynamics. A primary objective is to devise unconditionally stable and accurate time stepping procedures which lend themselves to an efficient implementation in concurrent machines. Some features of the new computer architecture are summarized. A brief survey of current efforts in the area is presented. A new class of concurrent procedures, or Group Implicit algorithms is introduced and analyzed. The numerical simulation shows that GI algorithms hold considerable promise for application in coarse grain as well as medium grain parallel computers.

2016-06-01

Captive animals exhibit stereotypic pacing in response to multiple causes, including the inability to escape from human contact. Environmental enrichment techniques can minimize pacing expression. By using an individual-based approach, we addressed whether the amount of time two males and a female jaguar (Panthera onca) devote to pacing varied with the number of visitors and tested the effectiveness of cinnamon and black pepper in reducing pacing. The amount of time that all jaguars engaged in pacing increased significantly with the number of visitors. Despite the difference between the males regarding age and housing conditions, both devoted significantly less time to pacing following the addition of both spices, which indicates their suitability as enrichment techniques. Mean time devoted to pacing among the treatments did not differ for the female. Our findings pointed out to the validity of individual-based approaches, as they can reveal how suitable olfactory stimuli are to minimizing stereotypies irrespective of particular traits.

Listening, Watching, and Reading: The Structure and Correlates of Entertainment Preferences

PubMed Central

Rentfrow, Peter J.; Goldberg, Lewis R.; Zilca, Ran

2010-01-01

People spend considerable amounts of time and money listening to music, watching TV and movies, and reading books and magazines, yet almost no attention in psychology has been devoted to understanding individual differences in preferences for such entertainment. The present research was designed to examine the structure and correlates of entertainment genre preferences. Analyses of the genre preferences of over 3,000 individuals revealed a remarkably clear factor structure. Using multiple samples, methods, and geographic regions, data converged to reveal five entertainment-preference dimensions: Communal, Aesthetic, Dark, Thrilling, and Cerebral. Preferences for these entertainment dimensions were uniquely related to demographics and personality traits. Results also indicated that personality accounted for significant proportions of variance in entertainment preferences over and above demographics. The results provide a foundation for developing and testing hypotheses about the psychology of entertainment preferences. PMID:20649744

The invention of infertility in the classical Greek world: medicine, divinity, and gender.

PubMed

Flemming, Rebecca

2013-01-01

The article examines the understandings of, and responses to, reproductive failure in the classical Greek world. It discusses explanations and treatments for non-procreation in a range of ancient Greek medical texts, focusing on the writings of the Hippocratic Corpus, which devote considerable energy to matters of fertility and generation, and places them alongside the availability of a divine approach to dealing with reproductive disruption, the possibility of asking various deities, including the specialist healing god Asclepius, for assistance in having children. Though the relations between these options are complex, they combine to produce a rich remedial array for those struggling with childlessness, the possibility that any impediment to procreation can be removed. Classical Greece, rather than the nineteenth century, or even 1978, is thus the time when "infertility," understood as an essentially reversible somatic state, was invented.

Most of the proposed objectives in this grant were achieved during the 3 year duration of the grant and its one year extension. In addition, shortly after initiation of the grant, the discovery of gullies on Mars apparently formed by recent seepage of fluids was announced. Together with partial support from the Astrobiology Institute, I devoted considerable effort during the grant interval into understanding the origin of these gullies because of their astrobiological significance. In addition, longstanding investigations of the environmental conditions of the Early Earth initiated years ago under previous NASA and NSF funding reached fruition and these were presented and published. This report summarizes the significant findings reported during the grant interval. Some of the work initiated during this interval has been completed under the subsequent Exobiology grant and will be reported at the appropriate time.

Is Biology Destiny? Birth Weight and Differential Parental Treatment

PubMed Central

Hsin, Amy

2016-01-01

Time diaries of sibling pairs from the PSID-CDS are used to determine whether maternal time investments compensate for or reinforce birth-weight differences among children. The findings demonstrate that the direction and degree of differential treatment vary by mother's education. Less-educated mothers devote more total time and more educationally oriented time to heavier-birth-weight children, whereas better-educated mothers devote more total and more educationally oriented time to lower-birth-weight children. The compensating effects observed among highly educated mothers are substantially larger than the reinforcing effects among the least-educated mothers. The findings show that families redistribute resources in ways that both compensate for and exacerbate early-life disadvantages. PMID:22865101

Jelinski, Murray D.; Campbell, John R.

2009-01-01

The objective of this study was to determine the number of hours veterinarians in western Canada work per week, how they apportion their time by species, and clinics’ hiring intentions for new veterinary associates. Of 1099 clinics contacted, 706 (64%) responded to the survey, representing 80% (1774/2227) of private practitioners in western Canada. Practitioners devoted 73% of their time to small animals (SA), 11% to beef practice, and 9% to horses. Sixty-four percent of clinics and 66% of practitioners were devoted exclusively to companion animal (SA and horses) practice; only 4% of clinics and 4% of practitioners were devoted exclusively to food animal practice. A total of 230 clinics were seeking to hire another veterinarian, representing 223 full-time equivalents (FTEs). When adjusted for clinics that did not respond, the total number of vacancies in western Canada could be as high as 347 FTEs with 57% of vacancies in companion animal practice. The survey, however, did not assess how determined the clinics were in their attempts to hire another associate. PMID:19949555

Effect of fossil fuels on the parameters of CO2 capture.

Nagy, Tibor; Mizsey, Peter

2013-08-06

The carbon dioxide capture is a more and more important issue in the design and operation of boilers and/or power stations because of increasing environmental considerations. Such processes, absorber desorber should be able to cope with flue gases from the use of different fossil primary energy sources, in order to guarantee a flexible, stable, and secure energy supply operation. The changing flue gases have significant influence on the optimal operation of the capture process, that is, where the required heating of the desorber is the minimal. Therefore special considerations are devoted to the proper design and control of such boiler and/or power stations equipped with CO2 capture process.

Diagnosing of pulmonary nodules by using computer-assisted diagnosing has received considerable theoretical, computational, and empirical research work, and considerable methods have been developed for detection and classification of pulmonary nodules on different formats of images including chest radiographs, computed tomography (CT), and positron emission tomography in the past five decades. The recent remarkable and significant progress in deep learning for pulmonary nodules achieved in both academia and the industry has demonstrated that deep learning techniques seem to be promising alternative decision support schemes to effectively tackle the central issues in pulmonary nodules diagnosing, including feature extraction, nodule detection, false-positive reduction, and benign-malignant classification for the huge volume of chest scan data. The main goal of this investigation is to provide a comprehensive state-of-the-art review of the deep learning aided decision support for pulmonary nodules diagnosing. As far as the authors know, this is the first time that a review is devoted exclusively to deep learning techniques for pulmonary nodules diagnosing. PMID:29780633

The role of population monitoring in the management of North American waterfowl

Despite the effort and expense devoted to large-scale monitoring programs, few existing programs have been designed with specific objectives in mind and few permit strong inferences about the dynamics of monitored systems. The waterfowl population monitoring programs of the U.S. Fish and Wildlife Service, Canadian Wildlife Service and state and provincial agencies provide a nice example with respect to program objectives, design and implementation. The May Breeding Grounds Survey provides an estimate of system state (population size) that serves two primary purposes in the adaptive management process: identifying the appropriate time-specific management actions and updating the information state (model weights) by providing a basis for evaluating predictions of competing models. Other waterfowl monitoring programs (e.g., banding program, hunter questionnaire survey, parts collection survey, winter survey) provide estimates of vital rates (rates of survival, reproduction and movement) associated with system dynamics and variables associated with management objectives (e.g., harvest). The reliability of estimates resulting from monitoring programs depends strongly on whether considerations about spatial variation and detection probability have been adequately incorporated into program design and implementation. Certain waterfowl surveys again provide nice examples of monitoring programs that incorporate these considerations.

To analyse the nature and content of advertising during children's popular television viewing times with the specific aims of (i) identifying the proportion of advertising time devoted to confectionery and potentially cariogenic products (those which readily give rise to dental caries, more commonly known as tooth decay); and (ii) determining whether there is a variation in the advertisement of confectionery and other high-sugar products within children's school holiday time v. outside holiday time.MethodIn five separate one-week periods, the output of the four most popular British children's commercial television channels was video-recorded during the most popular viewing times for children. In total, 503 h of television were recorded and analysed. Analysis of the recordings revealed that 16.4 % of advertising time was devoted to food products; 6.3 % of all advertising time was devoted to potentially cariogenic products. Sugared cereals were the most commonly advertised high-sugar product, followed by sweetened dairy products and confectionery (chi2 = 6524.8, df = 4, P < 0.001). The advertisement of confectionery and high-sugar foods appeared to be influenced by school holidays. Health-care professionals should be aware of the shift away from the advertisement of confectionery towards the promotion of foods that might be considered healthier but contain large amounts of hidden sugar.

The importance of hoof care in maintaining the health and soundness of a horse cannot be overstated. The aphorism, “No foot, no horse” still holds true. For equine ambulatory practitioners, the time devoted to a thorough understanding of the equine digit and it’s care is well worth the investment. The effort devoted to developing good relationships with individuals who will likely be responsible for implementing the changes suggested as a result of that understanding will be rewarded many times over in the course of the equine ambulatory practitioner’s career.

High-sensitivity acoustic sensors from nanofibre webs.

Considerable interest has been devoted to converting mechanical energy into electricity using polymer nanofibres. In particular, piezoelectric nanofibres produced by electrospinning have shown remarkable mechanical energy-to-electricity conversion ability. However, there is little data for the acoustic-to-electric conversion of electrospun nanofibres. Here we show that electrospun piezoelectric nanofibre webs have a strong acoustic-to-electric conversion ability. Using poly(vinylidene fluoride) as a model polymer and a sensor device that transfers sound directly to the nanofibre layer, we show that the sensor devices can detect low-frequency sound with a sensitivity as high as 266 mV Pa(-1). They can precisely distinguish sound waves in low to middle frequency region. These features make them especially suitable for noise detection. Our nanofibre device has more than five times higher sensitivity than a commercial piezoelectric poly(vinylidene fluoride) film device. Electrospun piezoelectric nanofibres may be useful for developing high-performance acoustic sensors.

Space industrialization: A national perspective

NASA Technical Reports Server (NTRS)

Reis, V. H.

1984-01-01

Space industrialization (or commercialization) has the potential to be a major player in America's space program. If this potential is to be realized, however, industrialization efforts must be considered within the context of the other major portions of the space program: shuttle, space station, and civil remote sensing. Further, development efforts must be based upon a sound scientific and technical understanding of the products and processes, and there must be a trained cadre of dedicated individuals willing to devote time and effort to this effort. There remain considerable risks and uncertainties. Given all this, the best path to follow would seem to be a long term, balanced commitment, emphasizing government, industry, and academia partnerships. Several points are addressed: (1) the place of space industrialization in the overall national space program; (2) the meaning of space industrialization with respect to the historic, national aims of space; and (3) specifically what is being industrialized.

NASA Remembers Astronaut Alan Bean - Moonwalker, Skylab Commander, Artist

NASA Image and Video Library

2018-05-26

Apollo 12 astronaut Alan Bean has died at the age of 86. Bean walked on the Moon in 1969, commanded the second Skylab crew in 1973 and went on in retirement to paint the remarkable worlds and sights he had seen like no other artist. Born in Wheeler, Texas, Bean got an aeronautical engineering degree from the University of Texas before joining the Navy, where he spent four years with a jet attack squadron. As a Navy test pilot, Bean flew several types of aircraft before he was selected with the third group of NASA astronauts in October 1963. He served as a backup for crewmembers on Gemini 10 and Apollo 9. After his Apollo and Skylab flights, Bean remained with NASA until 1981, when he retired to devote full time to painting. He followed that dream for many years at his home studio in Houston, with considerable success. His paintings were particularly popular among space enthusiasts.

People spend considerable amounts of time and money listening to music, watching TV and movies, and reading books and magazines, yet almost no attention in psychology has been devoted to understanding individual differences in preferences for such entertainment. The present research was designed to examine the structure and correlates of entertainment genre preferences. Analyses of the genre preferences of more than 3,000 individuals revealed a remarkably clear factor structure. Using multiple samples, methods, and geographic regions, data converged to reveal five entertainment-preference dimensions: Communal, Aesthetic, Dark, Thrilling, and Cerebral. Preferences for these entertainment dimensions were uniquely related to demographics and personality traits. Results also indicated that personality accounted for significant proportions of variance in entertainment preferences over and above demographics. The results provide a foundation for developing and testing hypotheses about the psychology of entertainment preferences. © 2011 The Authors. Journal of Personality © 2011, Wiley Periodicals, Inc.

Higher Order Chemistry Models in the CFD Simulation of Laser-Ablated Carbon Plumes

Greendyke, R. B.; Creel, J. R.; Payne, B. T.; Scott, C. D.

2005-01-01

Production of single-walled carbon nanotubes (SWNT) has taken place for a number of years and by a variety of methods such as laser ablation, chemical vapor deposition, and arc-jet ablation. Yet, little is actually understood about the exact chemical kinetics and processes that occur in SWNT formation. In recent time, NASA Johnson Space Center has devoted a considerable effort to the experimental evaluation of the laser ablation production process for SWNT originally developed at Rice University. To fully understand the nature of the laser ablation process it is necessary to understand the development of the carbon plume dynamics within the laser ablation oven. The present work is a continuation of previous studies into the efforts to model plume dynamics using computational fluid dynamics (CFD). The ultimate goal of the work is to improve understanding of the laser ablation process, and through that improved understanding, refine the laser ablation production of SWNT.

This paper is devoted to the problem of real nature of medicine, as it was seen in Polish school of the philosophy of the medicine. Is medicine more (or only) science, or is it an art was the crucial point of discussion, which was held in European philosophy of the medicine for the first time in late 19th century. The important voice in it was given by Polish scientists such as Zygmunt Kramsztyk, Henryk Nusbaum, Władysław Biegański, Edmund Biernacki, Władyslaw Szumowski and Ludwik Zembrzuski. How they understood place and meaning of medicine in the realm of human activities, in which points they found the same grounds and in which they differed, should be seen as the main topic for this article.

2006-07-24

Over the past five years we have devoted considerable time to solid-state NMR investigaitons of nuclei, which are traditionally known as "difficult" because of their small magnetic moments. These include quadrupolar nuclei such as 35Cl, 53 Cr, 91Zr, 95Mo, 99Ru, 131 Xe, as well as spin-1/2 nuclei such as 109Ag. While NMR studies of such isotopes remain challenging, the use of moderate to high magnetic field strengths together with a variety of enhancement techniques is leading to many interesting applications. In this talk some of our successes in studying these isotopes will be presented. For example, we will present preliminarymore » results of 131Xe NMR studies of solid sodium perxenate, as well as 109Ag NMR studies of silver dialkylphosphites.

Semiautomated Device for Batch Extraction of Metabolites from Tissue Samples

PubMed Central

2012-01-01

Metabolomics has become a mainstream analytical strategy for investigating metabolism. The quality of data derived from these studies is proportional to the consistency of the sample preparation. Although considerable research has been devoted to finding optimal extraction protocols, most of the established methods require extensive sample handling. Manual sample preparation can be highly effective in the hands of skilled technicians, but an automated tool for purifying metabolites from complex biological tissues would be of obvious utility to the field. Here, we introduce the semiautomated metabolite batch extraction device (SAMBED), a new tool designed to simplify metabolomics sample preparation. We discuss SAMBED’s design and show that SAMBED-based extractions are of comparable quality to extracts produced through traditional methods (13% mean coefficient of variation from SAMBED versus 16% from manual extractions). Moreover, we show that aqueous SAMBED-based methods can be completed in less than a quarter of the time required for manual extractions. PMID:22292466

Surgical management of gastric torsion.

PubMed

Parks, J

1979-05-01

Considerable investigation has been devoted to the gastric dilatation-torsion complex. An adequate explanation of its cause has yet to be made, or a means of prevention described. We do know of its highly lethal nature, especially if not aggressively treated, of the high incidence of recurrence, and of the associated pathophysiology. As surgeons, we must approach the patient in an aggressive systematic manner. Decompression and patient stabilization must be achieved prior to definitive surgical management. The surgery planned must correct the obvious pathologic state and include procedures designed to prevent recurrence of this condition. The tube gastrostomy technique promotes gastric fixation by dense adhesion bands exceeding that attainable by gastropexy alone. The procedure is easy to perform, requires little surgical time, and does not appear to be discomforting to the patient. In addition, the tube gastrostomy acts as a convenient decompressive pathway during the postoperative period, circumventing gastric intubation or pharyngostomy tube placement should distention occur.

Generating perfect fluid spheres in general relativity

2005-06-01

Ever since Karl Schwarzschild’s 1916 discovery of the spacetime geometry describing the interior of a particular idealized general relativistic star—a static spherically symmetric blob of fluid with position-independent density—the general relativity community has continued to devote considerable time and energy to understanding the general-relativistic static perfect fluid sphere. Over the last 90 years a tangle of specific perfect fluid spheres has been discovered, with most of these specific examples seemingly independent from each other. To bring some order to this collection, in this article we develop several new transformation theorems that map perfect fluid spheres into perfect fluid spheres. These transformation theorems sometimes lead to unexpected connections between previously known perfect fluid spheres, sometimes lead to new previously unknown perfect fluid spheres, and in general can be used to develop a systematic way of classifying the set of all perfect fluid spheres.

The Invention of Infertility in the Classical Greek World:

Flemming, Rebecca

2013-01-01

Summary The article examines the understandings of, and responses to, reproductive failure in the classical Greek world. It discusses explanations and treatments for non-procreation in a range of ancient Greek medical texts, focusing on the writings of the Hippocratic Corpus, which devote considerable energy to matters of fertility and generation, and places them alongside the availability of a divine approach to dealing with reproductive disruption, the possibility of asking various deities, including the specialist healing god Asclepius, for assistance in having children. Though the relations between these options are complex, they combine to produce a rich remedial array for those struggling with childlessness, the possibility that any impediment to procreation can be removed. Classical Greece, rather than the nineteenth century, or even 1978, is thus the time when “infertility,” understood as an essentially reversible somatic state, was invented. PMID:24362276

A Quantitative Evaluation of Dissolved Oxygen Instrumentation

1971-01-01

The implications of the presence of dissolved oxygen in water are discussed in terms of its deleterious or beneficial effects, depending on the functional consequences to those affected, e.g., the industrialist, the oceanographer, and the ecologist. The paper is devoted primarily to an examination of the performance of five commercially available dissolved oxygen meters. The design of each is briefly reviewed and ease or difficulty of use in the field described. Specifically, the evaluation program treated a number of parameters and user considerations including an initial check and trial calibration for each instrument and a discussion of the measurement methodology employed. Detailed test results are given relating to the effects of primary power variation, water-flow sensitivity, response time, relative accuracy of dissolved-oxygen readout, temperature accuracy (for those instruments which included this feature), error and repeatability, stability, pressure and other environmental effects, and test results obtained in the field. Overall instrument performance is summarized comparatively by chart.

Prescription drug advertising trends: a study of oral hypoglycemics.

1989-01-01

A content analysis of oral hypoglycemic drug advertisements was performed in selected medical journals published in the United States from 1963 to 1986. The 665 advertisements subsequently examined were studied for certain predetermined parameters in order to indicate trends. The trend results may be summarized as follows. As an extension of prescription drug advertising trends in general, oral hypoglycemic drug advertising showed an increasing length along with a subsequent decrease in the amount of space devoted to the copy portion of the advertisement. They also showed a decrease in the use of statistical information and rarely made references to competitors. Nongender specific, colored advertisements with product and use related appeals have become more common with the passage of time. Although the rationale and purpose behind advertising is unchanged, the format has changed considerably. These changes are primarily due to the enhancement of print technology and to some extent, the changing social environment.

It has been five years since the last in-depth American College of Nuclear Physicians/Society of Nuclear Medicine Symposium on the subject of single photon emission computed tomography (SPECT) was held. Because this subject was nominated as the single most desired topic we have selected SPECT imaging as the basis for this year's program. The objectives of this symposium are to survey the progress of SPECT clinical applications that have taken place over the last five years and to provide practical and timely guidelines to users of SPECT so that this exciting imaging modality can be fully integrated into the evaluationmore » of pathologic processes. The first half was devoted to a consideration of technical factors important in SPECT acquisition and the second half was devoted to those organ systems about which sufficient clinical SPECT imaging data are available. With respect to the technical aspect of the program we have selected the key areas which demand awareness and attention in order to make SPECT operational in clinical practice. These include selection of equipment, details of uniformity correction, utilization of phantoms for equipment acceptance and quality assurance, the major aspect of algorithms, an understanding of filtered back projection and appropriate choice of filters and an awareness of the most commonly generated artifacts and how to recognize them. With respect to the acquisition and interpretation of organ images, the faculty will present information on the major aspects of hepatic, brain, cardiac, skeletal, and immunologic imaging techniques.

A variety of bivalve mollusks (phylum Mollusca, class Bivalvia) constitute a prominent commodity in fisheries and aquacultures, but are also crucial in order to preserve our ecosystem's complexity and function. Bivalve mollusks, such as clams, mussels, oysters and scallops, are relevant bred species, and their global farming maintains a high incremental annual growth rate, representing a considerable proportion of the overall fishery activities. Bivalve mollusks are filter feeders; therefore by filtering a great quantity of water, they may bioaccumulate in their tissues a high number of microorganisms that can be considered infectious for humans and higher vertebrates. Moreover, since some pathogens are also able to infect bivalve mollusks, they are a threat for the entire mollusk farming industry. In consideration of the leading role in aquaculture and the growing financial importance of bivalve farming, much interest has been recently devoted to investigate the pathogenesis of infectious diseases of these mollusks in order to be prepared for public health emergencies and to avoid dreadful income losses. Several bacterial and viral pathogens will be described herein. Despite the minor complexity of the organization of the immune system of bivalves, compared to mammalian immune systems, a precise description of the different mechanisms that induce its activation and functioning is still missing. In the present review, a substantial consideration will be devoted in outlining the immune responses of bivalves and their repertoire of immune cells. Finally, we will focus on the description of antimicrobial peptides that have been identified and characterized in bivalve mollusks. Their structural and antimicrobial features are also of great interest for the biotechnology sector as antimicrobial templates to combat the increasing antibiotic-resistance of different pathogenic bacteria that plague the human population all over the world.

Best research practices in psychology: Illustrating epistemological and pragmatic considerations with the case of relationship science.

PubMed

Finkel, Eli J; Eastwick, Paul W; Reis, Harry T

2015-02-01

In recent years, a robust movement has emerged within psychology to increase the evidentiary value of our science. This movement, which has analogs throughout the empirical sciences, is broad and diverse, but its primary emphasis has been on the reduction of statistical false positives. The present article addresses epistemological and pragmatic issues that we, as a field, must consider as we seek to maximize the scientific value of this movement. Regarding epistemology, this article contrasts the false-positives-reduction (FPR) approach with an alternative, the error balance (EB) approach, which argues that any serious consideration of optimal scientific practice must contend simultaneously with both false-positive and false-negative errors. Regarding pragmatics, the movement has devoted a great deal of attention to issues that frequently arise in laboratory experiments and one-shot survey studies, but it has devoted less attention to issues that frequently arise in intensive and/or longitudinal studies. We illustrate these epistemological and pragmatic considerations with the case of relationship science, one of the many research domains that frequently employ intensive and/or longitudinal methods. Specifically, we examine 6 research prescriptions that can help to reduce false-positive rates: preregistration, prepublication sharing of materials, postpublication sharing of data, close replication, avoiding piecemeal publication, and increasing sample size. For each, we offer concrete guidance not only regarding how researchers can improve their research practices and balance the risk of false-positive and false-negative errors, but also how the movement can capitalize upon insights from research practices within relationship science to make the movement stronger and more inclusive.

The investigation described here examined ABC, CBS, and NBC news coverage of steroids in sports between March 1990 and May 2008. Employing a framing analysis guided by the health belief model (HBM), coverage of the barriers and benefits of using steroids is reported. Overall, the trend by these three news affiliates was to emphasize the illegality of using steroids, whereas considerably less coverage was devoted to the health costs, in terms of both severity and susceptibility, of using steroids. Furthermore, of the health costs reported, the specific consequences of steroid use varied considerably. The results are reported across four timeframes: 1990-2008, 1990-1996, 1997-2002, and 2003-2008.

The aim of the study was the assessment of leisure time among third-year students from the Faculty of Pharmacy of the Medical University of Lublin. It analysed quantity of time devoted to school activity and ways of spending free time. The study involved 114 students (82 women and 32 men). The study revealed that women had less free time than men, who, most probably did not attend some lectures. The most popular activities among the questioned students were: sleeping (average 6.8 hours a day), studying (average 3.6 hours a day), listening to the radio (average 2.9 hours a day), talking with friends (average 1.9 hours a day), personal hygiene (average 1.1 hours a day), watching TV (average 1.1 hours a day), housework. Students devoted the least of their free time on active rest, for example walking (women did it more often than men) or practising sport (more popular among men). Cultural life of the students consisted only of meetings with friends and going to the cinema (women did it more often). The least popular way of spending free time was going to the theatre, opera, concerts and exhibitions. Few students spent their time working. Their number increased significantly during holidays. The way of spending free time by third-year students from the Faculty of Pharmacy (both men and women) during the day was similar, differences related only to the amount of time devoted to each activity.

The devil is in the details: Comparisons of episodic simulations of positive and negative future events.

PubMed

Puig, Vannia A; Szpunar, Karl K

2017-08-01

Over the past decade, psychologists have devoted considerable attention to episodic simulation-the ability to imagine specific hypothetical events. Perhaps one of the most consistent patterns of data to emerge from this literature is that positive simulations of the future are rated as more detailed than negative simulations of the future, a pattern of results that is commonly interpreted as evidence for a positivity bias in future thinking. In the present article, we demonstrate across two experiments that negative future events are consistently simulated in more detail than positive future events when frequency of prior thinking is taken into account as a possible confounding variable and when level of detail associated with simulated events is assessed using an objective scoring criterion. Our findings are interpreted in the context of the mobilization-minimization hypothesis of event cognition that suggests people are especially likely to devote cognitive resources to processing negative scenarios.

2014-01-01

In the 1970s research studies concentrating on satellite measurements of Earth's radiation budget started at the NASA Langley Research Center. Since that beginning, considerable effort has been devoted to developing measurement techniques, data analysis methods, and time-space sampling strategies to meet the radiation budget science requirements for climate studies. Implementation and success of the Earth Radiation Budget Experiment (ERBE) and the Clouds and the Earth's Radiant Energy System (CERES) was due to the remarkable teamwork of many engineers, scientists, and data analysts. Data from ERBE have provided a new understanding of the effects of clouds, aerosols, and El Nino/La Nina oscillation on the Earth's radiation. CERES spacecraft instruments have extended the time coverage with high quality climate data records for over a decade. Using ERBE and CERES measurements these teams have created information about radiation at the top of the atmosphere, at the surface, and throughout the atmosphere for a better understanding of our climate. They have also generated surface radiation products for designers of solar power plants and buildings and numerous other applications

Meeting Disorders.

2017-12-01

Although meetings are central to organizational work, considerable time devoted to meetings in Academic Health Centers appears to be unproductively spent. The primary purposes of this article are to delineate and describe Meeting Disorders, pathological processes resulting in these inefficient and ineffective scenarios, and Meeting Fatigue Disorder (MFD), a clinical syndrome. The paper also offers preliminary approaches to remedies. The authors integrate observations made during tens of thousands of hours in administrative meetings in academic medical settings with information in the literature regarding the nature, causes and potential interventions for dysfunctional groups and meetings. Meeting Disorders, resulting from distinct pathologies of leadership and organization, constitute prevalent subgroups of the bureaucrapathologies, pathological conditions caused by dysfunctional bureaucratic processes that generate excesses of wasted time, effort, and other resources. These disorders also generate frustration and demoralization among participants, contributing to professional burnout. Meeting Fatigue Disorder (MFD) is a subjective condition that develops in individuals who overdose on these experiences and may reflect one manifestation of burnout. Meeting disorders and Meeting Fatigue Disorder occur commonly in bureaucratic life. Resources and potential remedies are available to help ameliorate their more deleterious effects.

Most of this hearings record is devoted to brief statements to the committee and prepared statements submitted for the record by: (1) Dr. David Kay, Deputy Leader, IAEA Action Team for Nuclear Inspections; and (2) Dr. Hans Blix, Director General, IAEA. Dr. Kay spent considerable time in Iraq during the seven IAEA inspections of Iraqi facilities between May 14-23, 1991 and October 11-21, 1991. He says (1) it is overwhelmingly clear that Iraq had a clandestine nuclear weapons program of considerable breadth; and (2) there is a very high probability that Iraq is still withholding information from the inspection effortmore » of the IAEA. He concludes that IAEA, with firm backing of the U.N. Security Council and a minimum of constraints, has a substantial proven capacity to carry out inspections. Dr. Blix reviews briefly the history of the IAEA inspection effort, starting with the 1950s' Atoms for Peace Program. He emphasizes that the one factor that enabled IAEA inspectors to find out in 5 months in Iraq what had not been uncovered in 10 years, was intelligence information; further, IAEA will make special efforts in the future to obtain such intelligence information.« less

Aeroelastic Tailoring for Stability Augmentation and Performance Enhancements of Tiltrotor Aircraft

Nixon, Mark W.; Piatak, David J.; Corso, Lawrence M.; Popelka, David A.

1999-01-01

The requirements for increased speed and productivity for tiltrotors has spawned several investigations associated with proprotor aeroelastic stability augmentation and aerodynamic performance enhancements. Included among these investigations is a focus on passive aeroelastic tailoring concepts which exploit the anisotropic capabilities of fiber composite materials. Researchers at Langley Research Center and Bell Helicopter have devoted considerable effort to assess the potential for using these materials to obtain aeroelastic responses which are beneficial to the important stability and performance considerations of tiltrotors. Both experimental and analytical studies have been completed to examine aeroelastic tailoring concepts for the tiltrotor, applied either to the wing or to the rotor blades. This paper reviews some of the results obtained in these aeroelastic tailoring investigations and discusses the relative merits associated with these approaches.

2015-03-01

A considerable progress in recognition techniques for many non-Arabic characters has been achieved. In contrary, few efforts have been put on the research of Arabic characters. In any Optical Character Recognition (OCR) system the segmentation step is usually the essential stage in which an extensive portion of processing is devoted and a considerable share of recognition errors is attributed. In this research, a novel segmentation approach for machine Arabic printed text with diacritics is proposed. The proposed method reduces computation, errors, gives a clear description for the sub-word and has advantages over using the skeleton approach in which the data and information of the character can be lost. Both of initial evaluation and testing of the proposed method have been developed using MATLAB and shows 98.7% promising results.

The paper is devoted to an experimental study of laminar-turbulent transition in a three-dimensional supersonic boundary layer. The experiments were conducted at the low nose supersonic wind tunnel T-325 of ITAM at Mach numbers M=2 - 4. Model is a symmetrical wing with a 45° sweep angle, a 3 percent-thick circular-arc airfoil. The influence of flow parameters, such as the Mach number, unit Reynolds number, angle of attack, level of perturbations on the transitions to turbulence are on the consideration. Transition Reynolds numbers are obtained. Analysis of all obtained data allow to determine reliable value of Retr of swept wing supersonic boundary layer, that especially important at consideration of experiments fulfilled at different flow conditions in different wind tunnels.

Shay, J J

1992-01-01

As family therapy of sexual abuse survivors has become more common, theoretical and technical issues have received considerable attention. Less attention has been devoted to the countertransference experience of the therapist. Unexamined therapist countertransference is a critical element in the treatment of these families, which markedly influences the nature and direction of treatment. Particular types of countertransference are presented here. In addition, the contention is made that countertransference is not only evoked by the particular presentation of the family members, but also by the therapist's unexplored political and moral beliefs.

Environmental Assessment for Sustainability and Resiliency for Ecological and Human Health

2015-01-01

Considerable attention has been devoted to environmental assessment and monitoring, primarily by physical and biological scientists, and more recently by social scientists. However, population growth and global change have resulted in an imperative to assess the resiliency of the environment to adapt to large scale changes and to continue to produce goods and services for future generations (sustainability). Changing land use needs or expectations may require the remediation and restoration of degraded or contaminated land. This paper provides an overview of monitoring types, and discusses how indicators for the different monitoring types can be developed to address questions of ecological health, human health, and whether restoration and remediation are effective. We suggest that along with more traditional types of monitoring, agencies should consider recovery indicators or metrics, as well as resiliency metrics. We suggest that one goal of assessment should be to determine if management, remediation, restoration, and mitigation reduce recovery time, thus reducing community vulnerability and enhancing resiliency to environmental stressors and disasters.

Cheng, Terence C; Joyce, Catherine M; Scott, Anthony

2013-06-01

The combination of public and private medical practice is widespread in many health systems and has important consequences for health care cost and quality. However, its forms and prevalence vary widely and are poorly understood. This paper examines factors associated with public and private sector work by medical specialists using a nationally representative sample of Australian doctors. We find considerable variations in the practice patterns, remuneration contracts and professional arrangements across doctors in different work sectors. Both specialists in mixed practice and private practice differ from public sector specialists with regard to their annual earnings, sources of income, maternity and other leave taken and number of practice locations. Public sector specialists are likely to be younger, to be international medical graduates, devote a higher percentage of time to education and research, and are more likely to do after hours and on-call work compared with private sector specialists. Gender and total hours worked do not differ between doctors across the different practice types. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

How Children Learn to Navigate the Symbolic World of Pictures: The Importance of the Artist's Mind and Differentiating Picture Modalities.

Allen, M L; Armitage, E

2017-01-01

Pictures offer a unique and essential contribution to our lives, both in terms of aesthetic pleasure and links to symbolic thought. As such, psychologists have devoted significant time to investigating how children acquire an understanding of pictures. This chapter focuses on two particular facets of this development: the role of the artist and the importance of picture modality. First, we review work that has focused on tracking children's ability to (a) map the relationship between the mental state of the artist and their pictures, and (b) incorporate such considerations into their evaluations of pictures. Drawing these literatures together provides an up-to-date account of how children acquire a mentalistic understanding of pictures. Second, we argue that a mature theory of pictures must enable children to distinguish between different picture types (e.g., photographs vs drawings), and therefore that picture modality should be incorporated into existing theoretical accounts of pictorial development. © 2017 Elsevier Inc.

Inherited diseases commonly emerge within pedigree dog populations, often due to use of repeatedly bred carrier sire(s) within a small gene pool. Accurate family records are usually available making linkage analysis possible. However, there are many factors that are intrinsically difficult about collecting DNA and collating pedigree information from a large canine population. The keys to a successful DNA collection program include (1) the need to establish and maintain support from the pedigree breed clubs and pet owners; (2) committed individual(s) who can devote the considerable amount of time and energy to coordinating sample collection and communicating with breeders and clubs; and (3) providing means by which genotypic and phenotypic information can be easily collected and stored. In this article we described the clinical characteristics of inherited occipital hypoplasia/syringomyelia (Chiari type I malformation) in the cavalier King Charles spaniel and our experiences in establishing a pedigree and DNA database to study the disease.

2009-01-01

The thirteenth biennial International Association of Geomagnetism and Aeronomy (IAGA) Workshop on Geomagnetic Observatory Instruments, Data Acquisition and Processing was held in the United States for the first time on June 9-18, 2008. Hosted by the U.S. Geological Survey's (USGS) Geomagnetism Program, the workshop's measurement session was held at the Boulder Observatory and the scientific session was held on the campus of the Colorado School of Mines in Golden, Colorado. More than 100 participants came from 36 countries and 6 continents. Preparation for the workshop began when the USGS Geomagnetism Program agreed, at the close of the twelfth workshop in Belsk Poland in 2006, to host the next workshop. Working under the leadership of Alan Berarducci, who served as the chairman of the local organizing committee, and Tim White, who served as co-chairman, preparations began in 2007. The Boulder Observatory was extensively renovated and additional observation piers were installed. Meeting space on the Colorado School of Mines campus was arranged, and considerable planning was devoted to managing the many large and small issues that accompany an international meeting. Without the devoted efforts of both Alan and Tim, other Geomagnetism Program staff, and our partners at the Colorado School of Mines, the workshop simply would not have occurred. We express our thanks to Jill McCarthy, the USGS Central Region Geologic Hazards Team Chief Scientist; Carol A. Finn, the Group Leader of the USGS Geomagnetism Program; the USGS International Office; and Melody Francisco of the Office of Special Programs and Continuing Education of the Colorado School of Mines. We also thank the student employees that the Geomagnetism Program has had over the years and leading up to the time of the workshop. For preparation of the proceedings, thanks go to Eddie and Tim. And, finally, we thank our sponsors, the USGS, IAGA, and the Colorado School of Mines.

This volume relates primarily to Time-of-Day rates standard, PURPA IB(d)3, and deals with the content and methods of providing rate and conservation information to customers when Time-of-Day rates are used. Information to customers in the Demonstration and Pilot Projects fell mainly into four categories: administrative communications; explanations of new rate structures; information and advice on load management; and facts, recommendations and encouragements about energy conservation and end-use improvement. Administrative communications were about such matters as the existence of Projects, their funding, their periods of performance, the selection of their test customers, conditions of participation, procedural changes during the tests, andmore » the time and conditions of ending the tests. These communications were important to good customer cooperation. All Demonstration Projects devoted considerable effort to the crucial task of clearly explaining the rationale of Time-of-Use (TOU) pricing and the test rate structures. The Projects then presented the concept of TOU pricing as a means of (a) fairly charging customers the true cost of their electricity and (b) rewarding them for shifting consumption to times when costs are less. For the most part, Demonstration Projects gave specific information on the individual customer's own rate structure and none on any others that were under test. The information was presented in face-to-face interviews, group presentations, television, radio, and print media, and traveling exhibits. The results are evaluated. (LCL)« less

The Effects of the Activation of Money and Credit Card vs. that of Activation of Spirituality - Which One Prompts Pro-Social Behaviours?

PubMed

Wierzbicki, Jakub; Zawadzka, Anna Maria

Pro-social behaviours may be prompted or inhibited depending on the situation. Numerous experiments show that, when exposed to the idea of money, people are less willing to help, devote their time or share their resources with others (Vohs et al. Science, 314, 1154-1156, 2006, Current Directions in Psychological Science, 17(3), 208-212, 2008). Conversely, when exposed to the idea of spirituality, they often cheat less and are more willing to help others (Mazar and Ariely Journal of Marketing Research, 45, 633-644, 2008; Randolph-Seng and Nielsen The International Journal for the Psychology of Religion, 17(4), 303-315, 2007). The aim of this article is to present the results of two experiments in which we activated thoughts about money, i.e. both cash and credit cards, and thoughts about spirituality in order to find out in what way these two kinds of activation may influence pro-social behaviours. In experiment 1, participants, when reminded of money, offered lower donations to others whereas those reminded of spirituality offered higher donations. In experiment 2, those participants reminded of money offered to devote less time to help others whereas those reminded of spirituality offered to devote more time to help others.

Local land-use policy is increasingly being recognized as fundamental to biodiversity conservation in the United States. Many planners and conservation scientists have called for broader use of planning and regulatory tools to support the conservation of biodiversity at local scales. Yet little is known about the pervasiveness of these practices. We conducted an on-line survey of county, municipal, and tribal planning directors (n =116) in 3 geographic regions of the United States: metropolitan Seattle, Washington; metropolitan Des Moines, Iowa; and the Research Triangle, North Carolina. Our objectives were to gauge the extent to which local planning departments address biodiversity conservation and to identify factors that facilitate or hinder conservation actions in local planning. We found that biodiversity conservation was seldom a major consideration in these departments. Staff time was mainly devoted to development mandates and little time was spent on biodiversity conservation. Regulations requiring conservation actions that might benefit biodiversity were uncommon, with the exception of rules governing water quality in all 3 regions and the protection of threatened and endangered species in the Seattle region. Planning tools that could enhance habitat conservation were used infrequently. Collaboration across jurisdictions was widespread, but rarely focused on conservation. Departments with a conservation specialist on staff tended to be associated with higher levels of conservation actions. Jurisdictions in the Seattle region also reported higher levels of conservation action, largely driven by state and federal mandates. Increased funding was most frequently cited as a factor that would facilitate greater consideration of biodiversity in local planning. There are numerous opportunities for conservation biologists to play a role in improving conservation planning at local scales.

The bonobo-dialium positive interactions: seed dispersal mutualism.

A positive interaction is any interaction between individuals of the same or different species (mutualism) that provides a benefit to both partners such as increased fitness. Here we focus on seed dispersal mutualism between an animal (bonobo, Pan paniscus) and a plant (velvet tamarind trees, Dialium spp.). In the LuiKotale rainforest southwest of Salonga National Park, Democratic Republic of Congo, seven species of the genus Dialium account for 29.3% of all trees. Dialium is thus the dominant genus in this forest. Dialium fruits make up a large proportion of the diet of a habituated bonobo community in this forest. During the 6 months of the fruiting season, more than half of the bonobos' feeding time is devoted to Dialium fruits. Furthermore, Dialium fruits contribute a considerable proportion of sugar and protein to bonobos' dietary intake, being among the richest fruits for these nutrients. Bonobos in turn ingest fruits with seeds that are disseminated in their feces (endozoochory) at considerable distances (average: 1.25 km after 24 hr of average transit time). Endozoochory through the gut causes loss of the cuticle protection and tegumentary dormancy, as well as an increase in size by water uptake. Thus, after gut passage, seeds are better able to germinate. We consider other primate species as a potential seed disperser and conclude that Dialium germination is dependent on passage through bonobo guts. This plant-animal interaction highlights positive effects between two major organisms of the Congo basin rainforest, and establishes the role of the bonobo as an efficient disperser of Dialium seeds.

Background Paradoxically, despite their longer life expectancy, women report poorer health than men. Time devoted to differing social roles could be an explanation for the observed gender differences in health among the elderly. The objective of this study was to explain gender differences in self-reported health among the elderly by taking time use activities, socio-economic positions, family characteristics and cross-national differences into account. Methods Data from the Multinational Time Use Study (MTUS) on 13,223 men and 18,192 women from Germany, Italy, Spain, UK and the US were analyzed. Multiple binary logistic regression models were used to examine the association between social factors and health for men and women separately. We further identified the relative contribution of different factors to total gender inequality in health using the Blinder-Oaxaca decomposition method. Results Whereas time allocated to paid work, housework and active leisure activities were positively associated with health, time devoted to passive leisure and personal activities were negatively associated with health among both men and women, but the magnitude of the association varied by gender and country. We found significant gender differences in health in Germany, Italy and Spain, but not in the other countries. The decomposition showed that differences in the time allocated to active leisure and level of educational attainment accounted for the largest health gap. Conclusions Our study represents a first step in understanding cross-national differences in the association between health status and time devoted to role-related activities among elderly men and women. The results, therefore, demonstrate the need of using an integrated framework of social factors in analyzing and explaining the gender and cross-national differences in the health of the elderly population.

The molecular basis of enzyme catalytic power and specificity derives from dynamic interactions between enzyme and substrate during catalysis. Although considerable effort has been devoted to understanding how conformational dynamics within enzymes affect catalysis, the role of conformational dynamics within protein substrates has not been addressed. Here, we examine the importance of substrate dynamics in the cleavage of Kunitz-bovine pancreatic trypsin inhibitor protease inhibitors by mesotrypsin, finding that the varied conformational dynamics of structurally similar substrates can profoundly impact the rate of catalysis. A 1.4-Å crystal structure of a mesotrypsin-product complex formed with a rapidly cleaved substrate reveals a dramatic conformational change in the substrate upon proteolysis. By using long all-atom molecular dynamics simulations of acyl-enzyme intermediates with proteolysis rates spanning 3 orders of magnitude, we identify global and local dynamic features of substrates on the nanosecond-microsecond time scale that correlate with enzymatic rates and explain differential susceptibility to proteolysis. By integrating multiple enhanced sampling methods for molecular dynamics, we model a viable conformational pathway between substrate-like and product-like states, linking substrate dynamics on the nanosecond-microsecond time scale with large collective substrate motions on the much slower time scale of catalysis. Our findings implicate substrate flexibility as a critical determinant of catalysis. PMID:27810896

A study on the role of powertrain system dynamics on vehicle driveability

NASA Astrophysics Data System (ADS)

Castellazzi, Luca; Tonoli, Andrea; Amati, Nicola; Galliera, Enrico

2017-07-01

Vehicle driveability describes the complex interactions between the driver and the vehicle, mainly related to longitudinal vibrations. Today, a relevant part of the driveability process optimisation is realised by means of track tests, which require a considerable effort due to the number of parameters (such as stiffness and damping components) affecting this behaviour. The drawback of this approach is that it is carried on at a stage when a design iteration becomes very expensive in terms of time and cost. The objective of this work is to propose a light and accurate tool to represent the relevant quantities involved in the driveability analysis, and to understand which are the main vehicle parameters that influence the torsional vibrations transmitted to the driver. Particular attention is devoted to the role of the tyre, the engine mount, the dual mass flywheel and their possible interactions. The presented nonlinear dynamic model has been validated in time and frequency domain and, through linearisation of its nonlinear components, allows to exploit modal and energy analysis. Objective indexes regarding the driving comfort are additionally considered in order to evaluate possible driveability improvements related to the sensitivity of powertrain parameters.

Space weather at Low Latitudes: Considerations to improve its forecasting

NASA Astrophysics Data System (ADS)

Chau, J. L.; Goncharenko, L.; Valladares, C. E.; Milla, M. A.

2013-05-01

In this work we present a summary of space weather events that are unique to low-latitude regions. Special emphasis will be devoted to events that occur during so-called quiet (magnetically) conditions. One of these events is the occurrence of nighttime F-region irregularities, also known Equatorial Spread F (ESF). When such irregularities occur navigation and communications systems get disrupted or perturbed. After more than 70 years of studies, many features of ESF irregularities (climatology, physical mechanisms, longitudinal dependence, time dependence, etc.) are well known, but so far they cannot be forecast on time scales of minutes to hours. We present a summary of some of these features and some of the efforts being conducted to contribute to their forecasting. In addition to ESF, we have recently identified a clear connection between lower atmospheric forcing and the low latitude variability, particularly during the so-called sudden stratospheric warming (SSW) events. During SSW events and magnetically quiet conditions, we have observed changes in total electron content (TEC) that are comparable to changes that occur during strong magnetically disturbed conditions. We present results from recent events as well as outline potential efforts to forecast the ionospheric effects during these events.

Elderly Mexican women's perceptions of exercise and conflicting role responsibilities.

2001-02-01

The purpose of this pilot study was to explore elderly Mexican women's readiness to exercise, and their multiple roles. Fifty older women were sampled from two separate neighborhoods of low socio-economic status. Readiness to exercise was examined using the Stages of Change - Exercise instrument with six categories: precontemplation nonbelievers, precontemplation believers, contemplation, preparation, action, and maintenance. Time devoted to the following functional roles was explored: wife, household, grandmother, personal care, and recreational. Women fell mainly under the first three stages of change both, precontemplation nonbelievers and believers, and the contemplation stage. The stages of change scale and role commitments were not significantly related. Nevertheless, precontemplators devoted less time in all the roles than the women in the other categories of stage of change.

Using Online Lectures to Make Time for Active Learning

2012-01-01

To make time in class for group activities devoted to critical thinking, we integrated a series of short online lectures into the homework assignments of a large, introductory biology course at a research university. The majority of students viewed the online lectures before coming to class and reported that the online lectures helped them to complete the in-class activity and did not increase the amount of time they devoted to the course. In addition, students who viewed the online lecture performed better on clicker questions designed to test lower-order cognitive skills. The in-class activities then gave the students practice analyzing the information in groups and provided the instructor with feedback about the students’ understanding of the material. On the basis of the results of this study, we support creating hybrid course models that allow students to learn the fundamental information outside of class time, thereby creating time during the class period to be dedicated toward the conceptual understanding of the material.

Air pollutants degrade floral scents and increase insect foraging times

NASA Astrophysics Data System (ADS)

Fuentes, Jose D.; Chamecki, Marcelo; Roulston, T.'ai; Chen, Bicheng; Pratt, Kenneth R.

2016-09-01

Flowers emit mixtures of scents that mediate plant-insect interactions such as attracting insect pollinators. Because of their volatile nature, however, floral scents readily react with ozone, nitrate radical, and hydroxyl radical. The result of such reactions is the degradation and the chemical modification of scent plumes downwind of floral sources. Large Eddy Simulations (LES) are developed to investigate dispersion and chemical degradation and modification of floral scents due to reactions with ozone, hydroxyl radical, and nitrate radical within the atmospheric surface layer. Impacts on foraging insects are investigated by utilizing a random walk model to simulate insect search behavior. Results indicate that even moderate air pollutant levels (e.g., ozone mixing ratios greater than 60 parts per billion on a per volume basis, ppbv) substantially degrade floral volatiles and alter the chemical composition of released floral scents. As a result, insect success rates of locating plumes of floral scents were reduced and foraging times increased in polluted air masses due to considerable degradation and changes in the composition of floral scents. Results also indicate that plant-pollinator interactions could be sensitive to changes in floral scent composition, especially if insects are unable to adapt to the modified scentscape. The increase in foraging time could have severe cascading and pernicious impacts on the fitness of foraging insects by reducing the time devoted to other necessary tasks.

As teacher quality becomes a central issue in discussions of children's literacy, both researchers and policy makers alike express increasing concern with how teachers structure and allocate their lesson time for literacy-related activities as well as with what they know about reading development, processes, and pedagogy. The authors examined the beliefs, literacy knowledge, and proposed instructional practices of 121 first-grade teachers. Through teacher self-reports concerning the amount of instructional time they would prefer to devote to a variety of language arts activities, the authors investigated the structure of teachers' implicit beliefs about reading instruction and explored relationships between those beliefs, expertise with general or special education students, years of experience, disciplinary knowledge, and self-reported distribution of an array of instructional practices. They found that teachers' implicit beliefs were not significantly associated with their status as a regular or special education teacher, the number of years they had been teaching, or their disciplinary knowledge. However, it was observed that subgroups of teachers who highly valued particular approaches to reading instruction allocated their time to instructional activities associated with other approaches in vastly different ways. It is notable that the practices of teachers who privileged reading literature over other activities were not in keeping with current research and policy recommendations. Implications and considerations for further research are discussed.

Acquisition and Tracking Behavior of Phase-Locked Loops

NASA Technical Reports Server (NTRS)

Viterbi, A. J.

1958-01-01

Phase-locked or APC loops have found increasing applications in recent years as tracking filters, synchronizing devices, and narrowband FM discriminators. Considerable work has been performed to determine the noise-squelching properties of the loop when it is operating in or near phase lock and is functioning as a linear coherent detector. However, insufficient consideration has been devoted to the non-linear behavior of the loop when it is out of lock and in the process of pulling in. Experimental evidence has indicated that there is a strong tendency for phase-locked loops to achieve lock under most circumstances. However, the analysis which has appeared in the literature iis limited to the acquisition of a constant frequency reference signal with only one phase-locked loop filter configuration. This work represents an investigation of frequency acquisition properties of phase-locked loops for a variety of reference-signal behavior and loop configurations

As scaling of conventional silicon-based electronics is reaching its ultimate limit, considerable effort has been devoted to find new materials and new device concepts that could ultimately outperform standard silicon transistors. In this perspective two-dimensional transition metal dichalcogenides, such as MoS2 and WSe2, have recently attracted considerable interest thanks to their electrical properties. Here, we report the first experimental demonstration of a doping-free, polarity-controllable device fabricated on few-layer WSe2. We show how modulation of the Schottky barriers at drain and source by a separate gate, named program gate, can enable the selection of the carriers injected in the channel, and achieved controllable polarity behaviour with ON/OFF current ratios >106 for both electrons and holes conduction. Polarity-controlled WSe2 transistors enable the design of compact logic gates, leading to higher computational densities in 2D-flatronics.

Jack, R. F.

1984-01-01

Numerous public administration studies have indicated that local government agencies for a variety of reasons lack access to comprehensive information resources; furthermore, such entities are often unwilling or unable to share information regarding their own problem-solving innovations. The NASA/University of Kentucky Technology Applications Program devotes a considerable effort to providing scientific and technical information and assistance to local agencies, relying on its access to over 500 distinct online databases offered by 20 hosts. The author presents a subjective assessment, based on his own experiences, of several databases which may prove useful in obtaining information for this particular end-user community.

2013-01-01

The objective of the study was recognition of rural women's opinions concerning the degree of heaviness of work activities performed and obtaining the answer to the question: What is the actual level of loading rural women with work? The basic research instrument was a questionnaire form. A representative group of women aged 40-50 were selected for the study because this group had the most complete family structure. The study was conducted among rural women living in the commune of Zwierzyniec. Family size and multi-generationality were analyzed, as well as family members' assistance in household and field activities. The type of work performed was analyzed with consideration of the duration of work and body position while performing this work. Self-reported degree of loading with work on a farm was analyzed, and effective energy expenditure calculated for individual work activities performed by women, based on which the actual degree of loading with work was determined. The respondents generally perceived their loading with work as low. They considered household jobs as not loading with or not exerting any effect on their fatigue and state of health. A very weak statistical relationship was observed between the duration of loading with household jobs and the perceived degree of loading with this work. The Kołmogorov-Smirnov test showed that the evaluations expressed by women concerning the degree of loading with household chores did not depend on time devoted to these work activities. The majority of women similarly evaluated work load, irrespective of the actual degree of loading. Work activities performed in a household were classified according to work load as heavy, medium-heavy and mediocre. Subjective evaluations of work load by rural women considerably differed from the assessment performed using the work time schedule method.

Time spent in housework and leisure: links with parents' physiological recovery from work.

PubMed

Saxbe, Darby E; Repetti, Rena L; Graesch, Anthony P

2011-04-01

Spouses' balancing of housework and leisure activities at home may affect their recovery from work. This paper reports on a study of everyday family life in which 30 dual-earner couples were tracked around their homes by researchers who recorded their locations and activities every 10 min. For women, the most frequently pursued activities at home were housework, communication, and leisure; husbands spent the most time in leisure activities, followed by communication and housework. Spouses differed in their total time at home and their proportion of time devoted to leisure and housework activities, with wives observed more often in housework and husbands observed more often in leisure activities. Both wives and husbands who devoted more time to housework had higher levels of evening cortisol and weaker afternoon-to-evening recovery. For wives, husbands' increased housework time also predicted stronger evening cortisol recovery. When both spouses' activities were entered in the same model, leisure predicted husbands' evening cortisol, such that husbands who apportioned more time to leisure, and whose wives apportioned less time to leisure, showed stronger after-work recovery. These results suggest that the division of labor within couples may have implications for physical health.

Overweight and obesity rates among adolescents have increased substantially over the years. This study aimed to determine the body mass index (BMI) of students and parents and the relationship among media use, BMI, socio-demographic profiles, and snacking behaviour during television watching of secondary school students in Kuching South City. In accordance with the two-stage sampling method, a total of 316 adolescents aged 13-17 years from 7 secondary schools participated. Data were collected using questionnaire and anthropometric measurement. Independent t test, one-way ANOVA, Mann-Whitney U test, and chi-square test were performed. The mean BMI was 20.56 kg/m(2) (SD 4.33) for boys and 20.15 kg/m(2) (SD 3.91) for girls. No significant difference in terms of z score for BMI-for-age or socio-demographic factors was found. The mean duration of time devoted to media use was 4.69 hours (SD 2.93) on weekdays and 5.69 hours (SD 2.87) on weekends. Boys were found to spend more hours on media use than did the girls (t = 4.293, P < 0.01). Respondents were reported to consume more cereal compared with soft drinks and junk foods. Respondents whose fathers worked in the private sector devoted the fewest hours to media use, whereas those with self-employed fathers devoted the most time to media use. Respondents with mothers who were employed spent more time on media use than did respondents whose mothers were housewives (F = 4.067, P < 0.01). No significant difference was found between BMI and media time or snacking habits. This finding indicated that media time has no effect on body weight, because respondents were found to have normal weight and to consume less unhealthy food.

Time devoted to pre- and post-HIV test counselling in different health services according to participants of a rapid testing program in Madrid, Spain.

2014-02-01

The role of pre- and post-test counselling in new HIV testing strategies to reduce delayed diagnosis has been debated. Data on time devoted to counselling are scarce. One approach to this problem is to explore patients' views on the time devoted to counselling by venue of their last HIV test. We analysed data from 1568 people with a previous HIV test who attended a mobile HIV testing program in Madrid between May and December 2008. The majority (71%) were men (48% had had sex with other men), 51% were <30 years, 40% were foreigners, 56% had a university degree, and 40% had the most recent HIV test within the last year. As regards pre-test counselling, 30% stated they were told only that they would receive the test; 26.3% reported <10 min; 20.4% about 10 min; and 24.2%, 15 min or more. For post-test counselling: 40.2% stated they were told only that the test was negative; 24.9% reported 2-6 min; 16.4% about 10 min; and 18.5%, 15 min or more. The percentage of participants who reported no counselling time was higher among those tested in general health services: primary care, hospital settings and private laboratories (over 40% in pre-test, over 50% in post-test counselling). Women received less counselling time than men in almost all settings. Policies to expand HIV testing in general health services should take this current medical behaviour into account. Any mention of the need for counselling can be a barrier to expansion, because HIV is becoming less of a priority in developed countries. Oral consent should be the only requirement.

Australia's evolving food practices: a risky mix of continuity and change.

PubMed

Venn, Danielle; Banwell, Cathy; Dixon, Jane

2017-10-01

To investigate trends in five key aspects of Australian food practice which have been implicated in diet-related health risks, specifically energy intake. They are: the replacement of home-prepared foods by commercially prepared foods; consumer reliance on ultra-processed foods; de-structured dining; increased pace of eating; and a decline in commensal eating. Data were from repeated cross-sections from the national Household Expenditure and Time Use Surveys. Trends in food practice aspects were examined using indicators of food expenditure across different food groups and time spent eating and cooking, including where, when and with whom eating activities took place. Australia, 1989-2010. Nationally representative samples of Australian households. The share of the total food budget spent on food away from home rose steadily from 22·8 % in 1989 to 26·5 % in 2010, while spending on ultra-processed foods increased. The basic patterning of meals and the pace of eating changed little, although people spent more time eating alone and at restaurants. Cooking time declined considerably, particularly for women. These changes have occurred over the same time that obesity and diet-related, non-communicable diseases have increased rapidly in Australia. Some aspects are implicated more than others: particularly the shift from domestic cooking to use of pre-prepared and ultra-processed foods, a reduction in time spent in food preparation and cooking, as well as an upsurge in time and money devoted to eating away from home. These are all likely to operate through the higher energy content of commercially prepared, compared with unprocessed or lightly processed, foods.

Conveying empathy to hospice family caregivers: Team responses to caregiver empathic communication

2012-01-01

Objective The goal of this study was to explore empathic communication opportunities presented by family caregivers and responses from interdisciplinary hospice team members. Methods Empathic opportunities and hospice team responses were analyzed from biweekly web-based videoconferences between family caregivers and hospice teams. The authors coded the data using the Empathic Communication Coding System (ECCS) and identified themes within and among the coded data. Results Data analysis identified 270 empathic opportunity-team response sequences. Caregivers expressed statements of emotion and decline most frequently. Two-thirds of the hospice team responses were implicit acknowledgments of caregiver statements and only one-third of the team responses were explicit recognitions of caregiver empathic opportunities. Conclusion Although hospice team members frequently express emotional concerns with family caregivers during one-on-one visits, there is a need for more empathic communication during team meetings that involve caregivers. Practice implications Hospice clinicians should devote more time to discussing emotional issues with patients and their families to enhance patient-centered hospice care. Further consideration should be given to training clinicians to empathize with patients and family caregivers. PMID:22554387

2007-01-01

Successful PCR starts with proper priming between an oligonucleotide primer and the template DNA. However, the inevitable risk of mismatched priming cannot be avoided in the currently used primer system, even though considerable time and effort are devoted to primer design and optimization of reaction conditions. Here, we report a novel dual priming oligonucleotide (DPO) which contains two separate priming regions joined by a polydeoxyinosine linker. The linker assumes a bubble-like structure which itself is not involved in priming, but rather delineates the boundary between the two parts of the primer. This structure results in two primer segments with distinct annealing properties: a longer 5'-segment that initiates stable priming, and a short 3'-segment that determines target-specific extension. This DPO-based system is a fundamental tool for blocking extension of non-specifically primed templates, and thereby generates consistently high PCR specificity even under less than optimal PCR conditions. The strength and utility of the DPO system are demonstrated here using multiplex PCR and SNP genotyping PCR.

The Ambulatory and Home Care Record: A Methodological Framework for Economic Analyses in End-of-Life Care

Guerriere, Denise N.; Coyte, Peter C.

2011-01-01

Provision of end-of-life care in North America takes place across a multitude of settings, including hospitals, ambulatory clinics and home settings. As a result, family caregiving is characteristically a major component of care within the home. Accordingly, economic evaluation of the end-of-life care environment must devote equal consideration to resources provided by the public health system as well as privately financed resources, such as time and money provided by family caregivers. This paper addresses the methods used to measure end-of-life care costs. The existing empirical literature will be reviewed in order to assess care costs with areas neglected in this body of literature to be identified. The Ambulatory and Home Care Record, a framework and tool for comprehensively measuring costs related to the provision and receipt of end-of-life care across all health care settings, will be described and proposed. Finally, areas for future work will be identified, along with their potential contribution to this body of knowledge. PMID:21629752

The primary goal of the funded task was to restore and distribute the ISO ATLAS-1 space science data set with enhanced software and database utilities. The first year was primarily dedicated to physically transferring the data from its original format to its initial CD archival format. The remainder of the first year was devoted to the verification of the restored data set and database. The second year was devoted to the enhancement of the data set, especially the development of IDL utilities and redesign of the database and search interface as needed. This period was also devoted to distribution of the rescued data set, principally the creation and maintenance of a web interface to the data set. The final six months was dedicated to working with NSSDC to create a permanent, off site, hive of the data set and supporting utilities. This time was also used to resolve last minute quality and design issues.

Objective To assess UK governmental and charity research funding in 2012 for cancer, coronary heart disease (CHD), dementia and stroke, and to make comparisons with 2008 levels. Design Analysis of research expenditure. Setting United Kingdom. Main outcome measures We identified UK governmental agencies and charities providing health research funding to determine the 2012 levels of funding for cancer, CHD, dementia and stroke. Levels of research funding were compared to burden of disease measures, including prevalence, disability adjusted life years and economic burden. Results The combined research funding into cancer, CHD, dementia and stroke by governmental and charity organisations in 2012 was £856 million, of which £544 million (64%) was devoted to cancer, £166 million (19%) to CHD, £90 million (11%) to dementia and £56 million (7%) to stroke. For every £10 of health and social care costs attributable to each disease, cancer received £1.08 in research funding, CHD £0.65, stroke £0.19 and dementia £0.08. A considerable shift in the distribution of government research funding was observed between 2008 and 2012. In 2008, 66% of governmental research funding into the four conditions under study was devoted to cancer, 21% to CHD, 9% to dementia and 4% to stroke. In 2012, the proportions devoted to dementia and stroke had increased to 21% and 12%, respectively, with cancer accounting for 45% of total research spend. Conclusions Although there has been much progress by government to increase levels of research funding for dementia and stroke, these areas remain underfunded when compared with the burden of disease.

The spiritual health of veterans with a history of suicide ideation

PubMed Central

Kopacz, Marek S.

2014-01-01

Introduction: In recent years, considerable empirical attention has been devoted to examining the increased risk of suicide observed in some Veteran populations. This has led to a renewed focus on developing novel support options which can be used to respond to Veterans in distress, reducing their risk of suicide. Spirituality and religion, however, have been largely absent from any public discourse related to suicide prevention, not least of all in Veteran populations. Aim: The aim of this cross-sectional study is to compare the self-rated spiritual health of Veterans with and without suicide ideation. Identifying differences which may exist between these two groups could highlight the relevance of spiritual well-being to Veteran suicide prevention efforts. Materials and Methods: Data were collected using pencil-and-paper surveys, called Spiritual Assessments, distributed within the general population of in- and outpatients at a U.S. Department of Veterans Affairs Medical Center. Using Likert-type scales, this study examines the self-rated spiritual health, spiritual devotion, and significance ascribed to spirituality in a sample of 5378 Veterans. Statistical analysis took place using chi-squared to examine differences in the distribution of responses between ideators and non-ideators. Results: Ideators significantly more often rated their spiritual health as worse than that of non-ideators. Even with similar levels of spiritual devotion or significance ascribed to spiritual life, ideators continued to significantly more often rate their spiritual health as worse than that of non-ideators. Conclusion: The results show that Veterans with suicide ideation more often rate their spiritual health as worse than that of Veterans without suicide ideation. This suggests that spiritual well-being may indeed be relevant to suicide prevention efforts in Veteran populations. PMID:25750787

For every £10 of health and social care costs attributable to each disease, cancer received £1.08 in research funding, CHD £0.65, stroke £0.19 and dementia £0.08. A considerable shift in the distribution of government research funding was observed between 2008 and 2012. In 2008, 66% of governmental research funding into the four conditions under study was devoted to cancer, 21% to CHD, 9% to dementia and 4% to stroke. In 2012, the proportions devoted to dementia and stroke had increased to 21% and 12%, respectively, with cancer accounting for 45% of total research spend. Although there has been much progress by government to increase levels of research funding for dementia and stroke, these areas remain underfunded when compared with the burden of disease.

The molecular basis of enzyme catalytic power and specificity derives from dynamic interactions between enzyme and substrate during catalysis. Although considerable effort has been devoted to understanding how conformational dynamics within enzymes affect catalysis, the role of conformational dynamics within protein substrates has not been addressed. Here, we examine the importance of substrate dynamics in the cleavage of Kunitz-bovine pancreatic trypsin inhibitor protease inhibitors by mesotrypsin, finding that the varied conformational dynamics of structurally similar substrates can profoundly impact the rate of catalysis. A 1.4-Å crystal structure of a mesotrypsin-product complex formed with a rapidly cleaved substrate reveals a dramatic conformational change in the substrate upon proteolysis. By using long all-atom molecular dynamics simulations of acyl-enzyme intermediates with proteolysis rates spanning 3 orders of magnitude, we identify global and local dynamic features of substrates on the nanosecond-microsecond time scale that correlate with enzymatic rates and explain differential susceptibility to proteolysis. By integrating multiple enhanced sampling methods for molecular dynamics, we model a viable conformational pathway between substrate-like and product-like states, linking substrate dynamics on the nanosecond-microsecond time scale with large collective substrate motions on the much slower time scale of catalysis. Our findings implicate substrate flexibility as a critical determinant of catalysis. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

LITERATURE FORENSICS? DOOR TO WHAT WAS KNOWN ...

EPA Pesticide Factsheets

Science's all-consuming drive to make new discoveries often risks losing sight of what was already known at one time - that which already exists in the published literature. Inadequate attention to the published literature and insufficient time devoted to its mining and synthesis into new knowledge is a problem faced by all disciplines, especially highly interdisciplinary fields such as environmental forensics, whose knowledge base is fragmented across numerous disciplines. While the conduct of science applies principles of quality assurance to a wide array of its processes, how pervasive are quality controls designed to ensure that planned or ongoing research has not been undertaken before? Has sufficient energy been devoted to mining what has already been discovered and synthesizing it into a larger, more useful perspective? This paper touches on the liabilities associated with insufficient examination of an exponentially growing published literature (

Language and communication difficulties may occur in the elderly population. This is the case of the tip-of-the-tongue phenomenon and receptive and auditory comprehension difficulties. Few studies have focused on examining the effects of social exposure on maintaining communication in the aging process. OBJECTIVES [1] To describe the communication map of healthy elderly subjects; [2] To search for associations between frequency and time dedicated to communication and cognitive and sociodemographic factors. METHODS Healthy elderly subjects were submitted to cognitive screening, the Token Test – Revised, and the Verbal Fluency test, and answered the ASHA-FACS and the Circles of Communication Partners questionnaires. RESULTS 55 subjects, 67% female, with ages over 60 years and varied schooling were included in the sample. Interlocutors in the circle of close friends and acquaintances predominated in the communication map, although the time devoted to communication with these partners was lower than in other circles. Overall, the elderly reported no deficits in language comprehension, with some reports of the tip-of-the-tongue phenomenon. Poor performances on the Token Test – Revised and in phonemic verbal fluency along with reports of communication functionality indicated that these subjects compensate for their problems. CONCLUSION Older subjects with lower schooling tended to predominantly communicate within the family circle. Within other circles, the number of hours devoted to communication and dialogue partners was not associated with age or schooling. The time devoted to the circle of communication with friends may indicate cognitive difficulties. PMID:29213862

Does the way physicians are paid influence the way they practice? The case of Canadian family physicians' work activity.

To investigate the impact of the mode of remuneration on the work activities of Canadian family physicians on: (a) direct patient care in office/clinic, (b) direct patient care in other settings and (c) indirect patient care. Because the mode of remuneration is potentially endogenous to the work activities undertaken by family physicians, an instrumental variable estimation procedure is considered. We also account for the fact that the determination of the allocation of time to different activities by physicians may be undertaken simultaneously. To this end, we estimate a system of work activity equations and allow for correlated errors. Our results show that the mode of remuneration has little effect on the total hours worked after accounting for the endogeneity of remuneration schemes; however it does affect the allocation of time to different activities. We find that physicians working in non-fee-for-service remuneration schemes spend fewer hours on direct patient care in the office/clinic, but devote more hours to direct patient care in other settings, and more hours on indirect patient care. Canadian family physicians working in non-fee-for-service settings spend fewer hours on direct patient care in the office/clinic, but devote more hours to direct patient care in other settings and devote more hours to indirect patient care. The allocation of time in non-fee-for-service practices may have some implications for quality improvement. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Re-evaluation Of The Shallow Seismicity On Mt Etna Applying Probabilistic Earthquake Location Algorithms.

NASA Astrophysics Data System (ADS)

Tuve, T.; Mostaccio, A.; Langer, H. K.; di Grazia, G.

2005-12-01

A recent research project carried out together with the Italian Civil Protection concerns the study of amplitude decay laws in various areas on the Italian territory, including Mt Etna. A particular feature of seismic activity is the presence of moderate magnitude earthquakes causing frequently considerable damage in the epicentre areas. These earthquakes are supposed to occur at rather shallow depth, no more than 5 km. Given the geological context, however, these shallow earthquakes would origin in rather weak sedimentary material. In this study we check the reliability of standard earthquake location, in particular with respect to the calculated focal depth, using standard location methods as well as more advanced approaches such as the NONLINLOC software proposed by Lomax et al. (2000) using it with its various options (i.e., Grid Search, Metropolis-Gibbs and Oct-Tree) and 3D velocity model (Cocina et al., 2005). All three options of NONLINLOC gave comparable results with respect to hypocenter locations and quality. Compared to standard locations we note a significant improve of location quality and, in particular a considerable difference of focal depths (in the order of 1.5 - 2 km). However, we cannot find a clear bias towards greater or lower depth. Further analyses concern the assessment of the stability of locations. For this purpose we carry out various Monte Carlo experiments perturbing travel time reading randomly. Further investigations are devoted to possible biases which may arise from the use of an unsuitable velocity model.

Segmentation of acute pyelonephritis area on kidney SPECT images using binary shape analysis

Acute pyelonephritis is a serious disease in children that may result in irreversible renal scarring. The ability to localize the site of urinary tract infection and the extent of acute pyelonephritis has considerable clinical importance. In this paper, we are devoted to segment the acute pyelonephritis area from kidney SPECT images. A two-step algorithm is proposed. First, the original images are translated into binary versions by automatic thresholding. Then the acute pyelonephritis areas are located by finding convex deficiencies in the obtained binary images. This work gives important diagnosis information for physicians and improves the quality of medical care for children acute pyelonephritis disease.

The application of conforming mixed finite element methods to obtain approximate solutions of linearized Navier-Stokes equations is examined. Attention is given to the convergence rates of various finite element approximations of the pressure and the velocity field. The optimality of the convergence rates are addressed in terms of comparisons of the approximation convergence to a smooth solution in relation to the best approximation available for the finite element space used. Consideration is also devoted to techniques for efficient use of a Gaussian elimination algorithm to obtain a solution to a system of linear algebraic equations derived by finite element discretizations of linear partial differential equations.

Strategic costs and preferences revelation in the allocation of resources for health care.

Levaggi, Laura; Levaggi, Rosella

2010-09-01

This article examines the resources allocation process in the internal market for health care in an environment characterised by asymmetry of information. We analyse the strategic behaviour of the provider and show how, by misreporting its cost function and reservation utility, it might shift the allocation of resources away from the purchaser's objectives. Although the fundamental importance of equity, efficiency and risk aversion considerations which have been the traditional focus of the literature on allocation of resources should not be denied, this paper shows that contracts and internal markets are not neutral instruments and more research should be devoted to studying their effects.

The Rescue of the Aesthetic Character of Existence in Kierkegaard Philosophy.

2015-08-01

The intention of this article is to develop considerations regarding the unity in all that constitutes the multifaceted work of Soren Kierkegaard. The guides to the subject of this investigation are the stages of existence. His work is devoted to considering the unity of all spheres in their original place, which is concrete existence. To search for this unity, Kierkegaard resumes the aesthetic element of existence, which had been abandoned since the Greeks, passing by Christianity and radicalizing itself since philosophers of subjectivity, to show that this abandon provokes the suppression of the aesthetic element, without which oneness is not possible.

Sputter-ion plating of coatings for protection of gas-turbine blades against high-temperature oxidation and corrosion

1982-01-01

Considerable effort is being devoted to the development of overlay coatings for protecting critical components such as turbine blades against high-temperature oxidation, corrosion, and erosion damage in service. The most commercially advanced methods for depositing coatings are electron-beam evaporation and plasma spraying. Sputter-ion plating (SIP) offers a potentially cheaper and simpler alternative method for depositing overlays. Experimental work on SIP of Co-Cr-Al-Y and Ni-Cr-Al-Ti alloy coatings is described. Results are presented of metallographic assessment of these coatings, and of the results obtained from high-velocity testing using a gas-turbine simulator rig.

2014-07-16

The food and beverage industry is seeking to broaden the palette of naturally derived colorants. Although considerable effort has been devoted to the search for new blue colorants in fruits and vegetables, less attention has been directed toward blue compounds from other sources such as bacteria and fungi. The current work reviews known organic blue compounds from natural plant, animal, fungal, and microbial sources. The scarcity of blue-colored metabolites in the natural world relative to metabolites of other colors is discussed, and structural trends common among natural blue compounds are identified. These compounds are grouped into seven structural classes and evaluated for their potential as new color additives.

Solar origins of coronal mass ejections

NASA Technical Reports Server (NTRS)

Kahler, Stephen

1987-01-01

The large scale properties of coronal mass ejections (CMEs), such as morphology, leading edge speed, and angular width and position, have been cataloged for many events observed with coronagraphs on the Skylab, P-78, and SMM spacecraft. While considerable study has been devoted to the characteristics of the SMEs, their solar origins are still only poorly understood. Recent observational work has involved statistical associations of CMEs with flares and filament eruptions, and some evidence exists that the flare and eruptive-filament associated CMEs define two classes of events, with the former being generally more energetic. Nevertheless, it is found that eruptive-filament CMEs can at times be very energetic, giving rise to interplanetary shocks and energetic particle events. The size of the impulsive phase in a flare-associated CME seems to play no significant role in the size or speed of the CME, but the angular sizes of CMEs may correlate with the scale sizes of the 1-8 angstrom x-ray flares. At the present time, He 10830 angstrom observations should be useful in studying the late development of double-ribbon flares and transient coronal holes to yield insights into the CME aftermath. The recently available white-light synoptic maps may also prove fruitful in defining the coronal conditions giving rise to CMEs.

Crew Roles and Interactions in Scientific Space Exploration

Future piloted space exploration missions will focus more on science than engineering, a change which will challenge existing concepts for flight crew tasking and demand that participants with contrasting skills, values, and backgrounds learn to cooperate as equals. In terrestrial space flight analogs such as Desert Research And Technology Studies, engineers, pilots, and scientists can practice working together, taking advantage of the full breadth of all team members training to produce harmonious, effective missions that maximize the time and attention the crew can devote to science. This paper presents, in a format usable as a reference by participants in the field, a successfully tested crew interaction model for such missions. The model builds upon the basic framework of a scientific field expedition by adding proven concepts from aviation and human spaceflight, including expeditionary behavior and cockpit resource management, cooperative crew tasking and adaptive leadership and followership, formal techniques for radio communication, and increased attention to operational considerations. The crews of future spaceflight analogs can use this model to demonstrate effective techniques, learn from each other, develop positive working relationships, and make their expeditions more successful, even if they have limited time to train together beforehand. This model can also inform the preparation and execution of actual future spaceflights.

Pregnancy is a dynamic physiological state which is evidenced by several transient changes. These can develop as various physical signs and symptoms that can affect the patients health, perceptions and interactions with others in the environment. The patients may not always understand the relevance of the adaptations of their bodies to the health of their foetuses. A gestational woman requires various levels of support throughout this time, such as medical monitoring or intervention, preventive care and physical and emotional assistance. The dental management of pregnant patients requires special attention. Dentists, for example, may delay certain elective procedures so that they coincide with the periods of pregnancy which are devoted to maturation versus organogenesis. At other times, the dental care professionals need to alter their normal pharmacological armamentarium to address the patients’ needs versus the foetal demands. Applying the basics of preventive dentistry at the primary level will broaden the scope of the prenatal care. Dentists should encourage all the patients of the childbearing ages to seek oral health counseling and examinations as soon as they learn that they are pregnant. This article has reviewed some of the physiologic changes and the oral pathologies which are associated with pregnancy, and how these alterations can affect the dental care of the patient.

It Costs to Be Clean and Fit: Energetics of Comfort Behavior in Breeding-Fasting Penguins

PubMed Central

Viblanc, Vincent A.; Mathien, Adeline; Saraux, Claire; Viera, Vanessa M.; Groscolas, René

2011-01-01

Background Birds may allocate a significant part of time to comfort behavior (e.g., preening, stretching, shaking, etc.) in order to eliminate parasites, maintain plumage integrity, and possibly reduce muscular ankylosis. Understanding the adaptive value of comfort behavior would benefit from knowledge on the energy costs animals are willing to pay to maintain it, particularly under situations of energy constraints, e.g., during fasting. We determined time and energy devoted to comfort activities in freely breeding king penguins (Aptenodytes patagonicus), seabirds known to fast for up to one month during incubation shifts ashore. Methodology/Principal Findings A time budget was estimated from focal and scan sampling field observations and the energy cost of comfort activities was calculated from the associated increase in heart rate (HR) during comfort episodes, using previously determined equations relating HR to energy expenditure. We show that incubating birds spent 22% of their daily time budget in comfort behavior (with no differences between day and night) mainly devoted to preening (73%) and head/body shaking (16%). During comfort behavior, energy expenditure averaged 1.24 times resting metabolic rate (RMR) and the corresponding energy cost (i.e., energy expended in excess to RMR) was 58 kJ/hr. Energy expenditure varied greatly among various types of comfort behavior, ranging from 1.03 (yawning) to 1.78 (stretching) times RMR. Comfort behavior contributed 8.8–9.3% to total daily energy expenditure and 69.4–73.5% to energy expended daily for activity. About half of this energy was expended caring for plumage. Conclusion/Significance This study is the first to estimate the contribution of comfort behavior to overall energy budget in a free-living animal. It shows that although breeding on a tight energy budget, king penguins devote a substantial amount of time and energy to comfort behavior. Such findings underline the importance of comfort behavior for the fitness of colonial seabirds. PMID:21818253

Ebola and Marburg haemorrhagic fever viruses: major scientific advances, but a relatively minor public health threat for Africa.

PubMed

Leroy, E M; Gonzalez, J-P; Baize, S

2011-07-01

Ebola and Marburg viruses are the only members of the Filoviridae family (order Mononegavirales), a group of viruses characterized by a linear, non-segmented, single-strand negative RNA genome. They are among the most virulent pathogens for humans and great apes, causing acute haemorrhagic fever and death within a matter of days. Since their discovery 50 years ago, filoviruses have caused only a few outbreaks, with 2317 clinical cases and 1671 confirmed deaths, which is negligible compared with the devastation caused by malnutrition and other infectious diseases prevalent in Africa (malaria, cholera, AIDS, dengue, tuberculosis …). Yet considerable human and financial resourses have been devoted to research on these viruses during the past two decades, partly because of their potential use as bioweapons. As a result, our understanding of the ecology, host interactions, and control of these viruses has improved considerably. © 2011 The Authors.

A second goal was to determine possible generalization effects beyond the primary intervention setting. Students in two urban elementary physical education classes served as subjects, with a third class used as a comparison. The effects of the curriculum intervention were evaluated in the training setting and in the students' regular education classrooms using a multiple baseline across classrooms design. Results showed (a) an immediate increase in student leadership and independent conflict-resolution behaviors, (b) an increase in percentage of class time devoted to activity participation, and (c) decreases in the frequency of student off-task behavior and percentage of class time that students devoted to organizational tasks. Similar changes in student behavior were also observed in the regular classroom settings. PMID:16795872

A national survey of sexologists was carried out in France in 1998-1999, among the individuals listed in the professional directories and the telephone book as "sexologists." It described the sociodemographic characteristics of sexologists, their initial profession and training in sexology, sex therapy and psychotherapeutic techniques, and how they practice sexology. A total of 959 individuals were identified and surveyed. The response rate was 63%. Two thirds of the sexologists were physicians and 60% were men. French sexologists appeared to be segmented into three subgroups: (1) one-third were general practitioners, trained in sexology and psychotherapeutic approaches, recognized themselves as sexologists, and devoted 40% of their professional activity to sexology. Men were about two thirds of this group; (2) one-third were nonphysicians (including psychologists and other health professionals, such as social workers and nurses), recognized themselves as sex therapists and devoted one third of their time to sexology. Men and women were equally represented in this group; (3) one-third were specialists, with less training in sexology and psychotherapeutic techniques, and did not generally recognize themselves as sexologists. They devoted a lesser part of their time to sexology and had academic and hospital practice. Men comprised more than 75% of this group. This study raised the issue of the diversity of primary professions involved in the field of sexology and showed that sexology is a secondary professional choice for the majority of sexologists.

The main focus was the development, implementation, and calibration of methods for performing molecular electronic structure calculations to high accuracy. These various methods were then applied to a number of chemical reactions and species of interest to NASA, notably in the area of combustion chemistry. Among the development work undertaken was a collaborative effort to develop a program to efficiently predict molecular structures and vibrational frequencies using energy derivatives. Another major development effort involved the design of new atomic basis sets for use in chemical studies: these sets were considerably more accurate than those previously in use. Much effort was also devoted to calibrating methods for computing accurate molecular wave functions, including the first reliable calibrations for realistic molecules using full CI results. A wide variety of application calculations were undertaken. One area of interest was the spectroscopy and thermochemistry of small molecules, including establishing small molecule binding energies to an accuracy rivaling, or even on occasion surpassing, the experiment. Such binding energies are essential input to modeling chemical reaction processes, such as combustion. Studies of large molecules and processes important in both hydrogen and hydrocarbon combustion chemistry were also carried out. Finally, some effort was devoted to the structure and spectroscopy of small metal clusters, with applications to materials science problems.

Ke, Yonggang; Castro, Carlos; Choi, Jong Hyun

2018-06-04

Structural DNA nanotechnology utilizes synthetic or biologic DNA as designer molecules for the self-assembly of artificial nanostructures. The field is founded upon the specific interactions between DNA molecules, known as Watson-Crick base pairing. After decades of active pursuit, DNA has demonstrated unprecedented versatility in constructing artificial nanostructures with significant complexity and programmability. The nanostructures could be either static, with well-controlled physicochemical properties, or dynamic, with the ability to reconfigure upon external stimuli. Researchers have devoted considerable effort to exploring the usability of DNA nanostructures in biomedical research. We review the basic design methods for fabricating both static and dynamic DNA nanostructures, along with their biomedical applications in fields such as biosensing, bioimaging, and drug delivery.

Tea has a long history of medicinal and dietary use. Tea polysaccharide (TPS) is regarded as one of the main bioactive constituents of tea and is beneficial for health. Over the last decades, considerable efforts have been devoted to the studies on TPS: extraction, structural feature and bioactivity of TPS. However, it has been received much less attention compared with tea polyphenols. In order to provide new insight for further development of TPS in functional foods, in present review we summarize the recent literature, update the information and put forward future perspectives on TPS covering its extraction, purification, quantitative determination techniques as well as physicochemical characterization and bioactivities.

Employing a set of experiments devoted to examining the effect of surface finish (riblets) on convective heat transfer as an example, this technical note seeks to explore the notion that precision uncertainties in experiments can be reduced by repeated trials and averaging. This scheme for bias error reduction can give considerable advantage when parametric effects are investigated experimentally. When the results of an experiment are presented as a ratio with the baseline results, a large reduction in the overall uncertainty can be achieved when all the bias limits in the variables of the experimental result are fully correlated with thosemore » of the baseline case. 4 refs.« less

Entanglement is often verified by a violation of an inequality like a Bell inequality or an entanglement witness. Considerable effort has been devoted to the optimization of such inequalities in order to obtain a high violation. We demonstrate theoretically and experimentally that such an optimization does not necessarily lead to a better entanglement test, if the statistical error is taken into account. Theoretically, we show for different error models that reducing the violation of an inequality can improve the significance. Experimentally, we observe this phenomenon in a four-photon experiment, testing the Mermin and Ardehali inequality for different levels of noise. Furthermore, we provide a way to develop entanglement tests with high statistical significance.

Background: Overweight and obesity rates among adolescents have increased substantially over the years. This study aimed to determine the body mass index (BMI) of students and parents and the relationship among media use, BMI, socio-demographic profiles, and snacking behaviour during television watching of secondary school students in Kuching South City. Methods: In accordance with the two-stage sampling method, a total of 316 adolescents aged 13–17 years from 7 secondary schools participated. Data were collected using questionnaire and anthropometric measurement. Independent t test, one-way ANOVA, Mann–Whitney U test, and chi-square test were performed. Results: The mean BMI was 20.56 kg/m2 (SD 4.33) for boys and 20.15 kg/m2 (SD 3.91) for girls. No significant difference in terms of z score for BMI-for-age or socio-demographic factors was found. The mean duration of time devoted to media use was 4.69 hours (SD 2.93) on weekdays and 5.69 hours (SD 2.87) on weekends. Boys were found to spend more hours on media use than did the girls (t = 4.293, P < 0.01). Respondents were reported to consume more cereal compared with soft drinks and junk foods. Respondents whose fathers worked in the private sector devoted the fewest hours to media use, whereas those with self-employed fathers devoted the most time to media use. Respondents with mothers who were employed spent more time on media use than did respondents whose mothers were housewives (F = 4.067, P < 0.01). No significant difference was found between BMI and media time or snacking habits. Conclusion: This finding indicated that media time has no effect on body weight, because respondents were found to have normal weight and to consume less unhealthy food. PMID:22135599

Invited article: is it time for neurohospitalists?

PubMed

Freeman, William D; Gronseth, Gary; Eidelman, Benjamin H

2008-04-08

Explosive growth of hospital-based medicine specialists, termed hospitalists, has occurred in the past decade. This was fueled by pressures within the American health care system for timely, cost-effective, and high-quality care and by the growing chasm between inpatient and outpatient care. In this article, we sought to answer five questions: 1) What is a neurohospitalist? 2) How many neurohospitalists practice in the United States? 3) What are potential advantages of neurohospitalists? 4) What are the challenges of implementing a neurohospitalist practice? 5) What effect does a neurohospitalist have on clinical outcomes? We queried biomedical databases (e.g., PubMed) by using the search terms "hospitalist," "neurohospitalist," and "neurology hospitalist." We also searched the Society of Hospital Medicine and the American Academy of Neurology Dendrite classified advertisement Web sites for hospitalist and neurology hospitalist growth by using the same search terms. We defined neurology hospitalists (neurohospitalists) as neurologists who devote at least one-quarter of their time managing inpatients with neurologic disease. Although the number of hospitalists has grown considerably over the past decade, limited data on neurohospitalists exist. Advertisements for neurohospitalist positions have increased from 2003 through 2007, but accurate assessment of growth is limited by the lack of a central organizational affiliation and unifying terminology. Health care pressures spawned the growth of medicine and pediatric hospitalists, who provide efficient, cost-effective care by reducing the length of hospitalization. Because neurologists experience the same pressures, we expect neurohospitalists to increase in number, especially within areas that have sufficient inpatient volume and resources.

Jacopo Berengario was born in Carpi, a medieval city close to Modena (northern Italy), circa 1460. He studied medicine at Bologna University and, in 1489, graduated in philosophy and medicine. He was appointed lecturer in anatomy and surgery at the same university, a position that he maintained for 24 years. Between 1514 and 1523, Berengario published some important anatomic and surgical works, which gave considerable fame to him.Commentaria... supra Anatomiam Mundini (Commentary... on the Anatomy of Mondino), published in 1521, constitutes the first example of an illustrated anatomic textbook ever printed. The anatomic illustrations were intended for explaining the text. Artistically speaking, the plates are typical examples of the Renaissance period and worthy of the greatest consideration.De Fractura Calvae sive Cranei (On Fracture of the Calvaria or Cranium), published in Bologna in 1518, is the first treatise devoted to head injuries ever printed. It is a landmark in the development of cranial surgery that went through numerous editions. The text was prepared in 2 months and dedicated to Lorenzo de' Medici, Duke of Urbino, who experienced a skull injury in the occipital region. Berengario wanted to demonstrate to other physicians his knowledge of anatomy and his expertise on the brain and head traumas. The book includes the illustration of an entire surgical kit or a corpus instrumentorum for performing cranial operations, which appeared for the first time in a printed book. However, Berengario's highly commendable aim was to indicate to the reader the step-by-step procedure of craniotomy for management of skull fractures along with the sequential use of the previously presented instruments.

At JET, the potential of fast image processing for real-time purposes is thoroughly investigated. Particular attention is devoted to smart sensors based on system on chip technology. The data of the infrared cameras were processed with a chip implementing a cellular nonlinear network (CNN) structure so as to support and complement the magnetic diagnostics in the real-time localization of the strike-point position in the divertor. The circuit consists of two layers of complementary metal-oxide semiconductor components, the first being the sensor and the second implementing the actual CNN. This innovative hardware has made it possible to determine the position ofmore » the maximum thermal load with a time resolution of the order of 30 ms. Good congruency has been found with the measurement from the thermocouples in the divertor, proving the potential of the infrared data in locating the region of the maximum thermal load.

Physics Back in TIME

2014-03-01

Recently, I came into possession of an unusual item: a collection of 1928 TIME magazines. I began flipping through the pages out of sheer curiosity—and was soon astonished by the scale and the depth of their physics coverage. Back then, TIME had a special "Science" section in almost every issue and devoted quite a bit of space to the events that would hardly be mentioned in any popular magazine these days. Some of them were fleeting and merely curious, some truly timeless. Many of the articles and notes were devoted to physics: the people, the discoveries, the inventions, the conventions. I found the reading both entertaining and enlightening and would like to offer a sampler here. I hope that these little tidbits of history will lighten up the classroom discussions and help inspire your students by reminding them that physics is a dynamic, ever-changing field to which they may well contribute one day. I have found that my own students love it when a little bit of history is brought up; it always generates interesting questions and seems to spark the students' interest in the topic.

Microchemical and microstructural characterisation of medieval and post-medieval ceramic glaze coatings

NASA Astrophysics Data System (ADS)

Alaimo, R.; Bultrini, G.; Fragalà, I.; Giarrusso, R.; Montana, G.

A large number of ceramic samples (from the 10th to the 19th century), found during the excavation of Sicilian archaeological sites (Syracuse, Caltagirone, Sciacca and Piazza Armerina), have been studied by combining scanning electron microscopy, energy-dispersive X-ray spectrometry and optical microscopy. Attention has been focused on the microchemical and microstructural properties of the painted surfaces to investigate the nature of the enamels and pigments in the decorative layers. The general perspective has been the identification of consistent archeometric criteria, other than the standard stylistic considerations, which can be used for a reliable recognition of the production sites. The results collected for each ceramic typology were used to cluster the different ceramic reference groups in a wide database suitable for a reliable discrimination of the provenance of artefacts. Moreover, the same compositional and microstructural data allow the identification of the raw materials used for pigments. There is evidence of some differences with existing information found in the literature concerning the formulas used in ancient times. Finally, attention has also been devoted to identify the technological aspects of the manufacturing techniques and firing conditions adopted for each typology of glaze coating depending on different ceramic materials .

Light and short arc rubs in rotating machines: Experimental tests and modelling

Pennacchi, P.; Bachschmid, N.; Tanzi, E.

2009-10-01

Rotor-to-stator rub is a non-linear phenomenon which has been analyzed many times in rotordynamics literature, but very often these studies are devoted simply to highlight non-linearities, using very simple rotors, rather than to present reliable models. However, rotor-to-stator rub is actually one of the most common faults during the operation of rotating machinery. The frequency of its occurrence is increasing due to the trend of reducing the radial clearance between the seal and the rotor in modern turbine units, pumps and compressors in order to increase efficiency. Often the rub occurs between rotor and seals and the analysis of the phenomenon cannot set aside the consideration of the different relative stiffness. This paper presents some experimental results obtained by means of a test rig in which rub conditions of real machines are reproduced. In particular short arc rubs are considered and the shaft is stiffer than the obstacle. Then a model, suitable to be employed for real rotating machinery, is presented and the simulations obtained are compared with the experimental results. The model is able to reproduce the behaviour of the test rig.

2008-03-01

Studies of the quantum dynamics of the electron spins in solid state systems has gained considerable interest recently due to their potential for use as quantum computing substrates. One class of materials, molecular magnets, are of particular importance, owing to the seemingly limitless array of spin configurations due to synthetic chemical flexibility. Efforts are currently devoted to minimizing decoherence times by diminishing dipolar effects. In this regard, we have carried out EPR measurements on small single crystals of 0.5% Ga doped Fe18 molecular antiferromagnetic wheels at temperatures down to 300 mK using planar resonators patterned on GaAs wafers. This system constitutes a dilute sample of S = 5/2 molecules dispersed within a sea of S = 0 (at low temperature) molecules, which significantly reduces dipolar interactions and might provide a means of observing Rabi oscillations in crystals of molecular magnets. Detailed angular dependence studies reveal significant anisotropy with D = 500 mK and E = 20 mK. The presence of second order anisotropy (E) is very unusual for such a high symmetry system and its interpretation will be discussed. Pulsed-EPR measurements and doping concentration dependence will also be discussed.

The Autopsy Tissue Program was begun in 1960. To date, tissues on 900 or more persons in 7 geographic regions have been collected and analyzed for plutonium content. The tissues generally consist of lung, liver, kidney, lymph, bone, and gonadal tissues for each individual. The original objective of the program was to determine the level of plutonium in human tissues due solely to fallout from weapons testing. The baseline thus established was to be used to evaluate future changes. From the first, this program was beset with chemical and statistical difficulties. Many factors whose effects were not recognized and notmore » planned for were found later to be important. Privacy and ethical considerations hindered the gathering of adequate data. Since the chemists were looking for amounts of plutonium very close to background, possible contamination was a very real problem. Widely used chemical techniques introduced a host of statistical problems. The difficulties encountered touch on areas common to large data sets, unusual outlier detection methods minimum detection limits, problems with aliquot sizes, and time-trends in the data. The conclusions point out areas to which the biologists will have to devote much more careful attention than was believed.« less

Optic flow cues guide flight in birds.

Bhagavatula, Partha S; Claudianos, Charles; Ibbotson, Michael R; Srinivasan, Mandyam V

2011-11-08

Although considerable effort has been devoted to investigating how birds migrate over large distances, surprisingly little is known about how they tackle so successfully the moment-to-moment challenges of rapid flight through cluttered environments [1]. It has been suggested that birds detect and avoid obstacles [2] and control landing maneuvers [3-5] by using cues derived from the image motion that is generated in the eyes during flight. Here we investigate the ability of budgerigars to fly through narrow passages in a collision-free manner, by filming their trajectories during flight in a corridor where the walls are decorated with various visual patterns. The results demonstrate, unequivocally and for the first time, that birds negotiate narrow gaps safely by balancing the speeds of image motion that are experienced by the two eyes and that the speed of flight is regulated by monitoring the speed of image motion that is experienced by the two eyes. These findings have close parallels with those previously reported for flying insects [6-13], suggesting that some principles of visual guidance may be shared by all diurnal, flying animals.

Crop Characteristics Research: Growth and Reflectance Analysis

NASA Technical Reports Server (NTRS)

Badhwar, G. D. (Principal Investigator)

1985-01-01

Much of the early research in remote sensing follows along developing spectral signatures of cover types. It was found, however, that a signature from an unknown cover class could not always be matched to a catalog value of known cover class. This approach was abandoned and supervised classification schemes followed. These were not efficient and required extensive training. It was obvious that data acquired at a single time could not separate cover types. A large portion of the proposed research has concentrated on modeling the temporal behavior of agricultural crops and on removing the need for any training data in remote sensing surveys; the key to which is the solution of the so-called 'signature extension' problem. A clear need to develop spectral estimaters of crop ontogenic stages and yield has existed even though various correlations have been developed. Considerable effort in developing techniques to estimate these variables was devoted to this work. The need to accurately evaluate existing canopy reflectance model(s), improve these models, use them to understand the crop signatures, and estimate leaf area index was the third objective of the proposed work. A synopsis of this research effort is discussed.

Tracking Blade Tip Vortices for Numerical Flow Simulations of Hovering Rotorcraft

NASA Technical Reports Server (NTRS)

Kao, David L.

2016-01-01

Blade tip vortices generated by a helicopter rotor blade are a major source of rotor noise and airframe vibration. This occurs when a vortex passes closely by, and interacts with, a rotor blade. The accurate prediction of Blade Vortex Interaction (BVI) continues to be a challenge for Computational Fluid Dynamics (CFD). Though considerable research has been devoted to BVI noise reduction and experimental techniques for measuring the blade tip vortices in a wind tunnel, there are only a handful of post-processing tools available for extracting vortex core lines from CFD simulation data. In order to calculate the vortex core radius, most of these tools require the user to manually select a vortex core to perform the calculation. Furthermore, none of them provide the capability to track the growth of a vortex core, which is a measure of how quickly the vortex diffuses over time. This paper introduces an automated approach for tracking the core growth of a blade tip vortex from CFD simulations of rotorcraft in hover. The proposed approach offers an effective method for the quantification and visualization of blade tip vortices in helicopter rotor wakes. Keywords: vortex core, feature extraction, CFD, numerical flow visualization

Computational thinking in life science education.

PubMed

Rubinstein, Amir; Chor, Benny

2014-11-01

We join the increasing call to take computational education of life science students a step further, beyond teaching mere programming and employing existing software tools. We describe a new course, focusing on enriching the curriculum of life science students with abstract, algorithmic, and logical thinking, and exposing them to the computational "culture." The design, structure, and content of our course are influenced by recent efforts in this area, collaborations with life scientists, and our own instructional experience. Specifically, we suggest that an effective course of this nature should: (1) devote time to explicitly reflect upon computational thinking processes, resisting the temptation to drift to purely practical instruction, (2) focus on discrete notions, rather than on continuous ones, and (3) have basic programming as a prerequisite, so students need not be preoccupied with elementary programming issues. We strongly recommend that the mere use of existing bioinformatics tools and packages should not replace hands-on programming. Yet, we suggest that programming will mostly serve as a means to practice computational thinking processes. This paper deals with the challenges and considerations of such computational education for life science students. It also describes a concrete implementation of the course and encourages its use by others.

1998-01-01

Accessibility and availability of drugs has been a matter of great concern for health services all over the world, especially for less developed countries. The World Health Organization has devoted considerable time to this matter, as evidenced in several documents and policies, such as model lists of essential drugs and the strategy "Health for All by the Year 2000". The WHO policy for essential drugs has been widely accepted, and the WHO List of Essential Drugs is now in the ninth revised edition. Although the essential drug policy has been well-accepted by health agencies and NGOs, the pharmaceutical industry has not proven willing to produce essential drugs at affordable prices. The purpose of this study is to examine price levels of essential drugs in Mexico. The evaluation was performed through a comparison of international and national prices for leading drugs in the respective therapeutic categories and included in the WHO model list of essential drugs. The study shows clearly that prices of essential brand-name drugs in Mexico are very high. Per capita consumption has remained stable despite a sharp decrease in the Mexican GDP since 1995. The article discusses the reasons for this and proposes measures to deal with the problem.

In socially feeding birds and mammals, as group size increases, individuals devote less time to scanning their environment and more time to feeding. This vigilance "group size effect" has long been attributed to the anti-predatory benefits of group living, but many investigators have suggested that this effect may be driven by scramble competition for limited...

Bush, Joseph; Langley, Christopher A; Jenkins, Duncan; Johal, Jaspal; Huckerby, Clair

2017-12-27

This aim of this research was to characterise the breadth and volume of activity conducted by clinical pharmacists in general practice in Dudley Clinical Commissioning Group (CCG), and to provide quantitative estimates of both the savings in general practitioner (GP) time and the financial savings attributable to such activity. This descriptive observational study retrospectively analysed quantitative data collected by Dudley CCG concerning the activity of clinical pharmacists in GP practices during 2015. Over the 9-month period for which data were available, the 5.4 whole time equivalent clinical pharmacists operating in GP practices within Dudley CCG identified 23 172 interventions. Ninety-five per cent of the interventions identified were completed within the study period saving the CCG in excess of £1 000 000. During the 4 months for which resource allocation data were available, the clinical pharmacists saved 628 GP appointments plus an additional 647 h that GPs currently devote to medication review and the management of repeat prescribing. This research suggests that clinical pharmacists in general practice in Dudley CCG are able to deliver clinical interventions efficiently and in high volume. In doing so, clinical pharmacists were able to generate considerable financial returns on investment. Further work is recommended to examine the effectiveness and cost-effectiveness of clinical pharmacists in general practice in improving outcomes for patients. © 2017 Royal Pharmaceutical Society.

Alcmaeon of Croton.

PubMed

Debernardi, Alberto; Sala, Elena; D'Aliberti, Giuseppe; Talamonti, Giuseppe; Franchini, Antonia Francesca; Collice, Massimo

2010-02-01

IN THE LATTER half of the sixth century BC, Croton was the site of the most famous medical school in Magna Graecia, where diseases of the human body were examined in a scientific and experimental manner instead of by using the contemporary supernatural, nearly magical concepts. Alcmaeon was one of the most active physicians interested in human physiology in the medical tradition of Croton. Although Alcmaeon was devoted to science and was a skillful experimentalist, little is known about his life and his exact birth date. The relative isolation of Alcmaeon from the great philosophical currents of his time probably facilitated his unprejudiced methodology and may have prevented him from disclosing his theories and demonstrating their value. He pioneered the concept of the relationship between the brain and the mind and was the first to identify the brain as the center of understanding and the essential organ for perceptions, sensations, and thoughts. Through systematic observations, Alcmaeon brought many things to light about the characteristics of the eye and the presence of channels connecting head sensory organs to the brain. He stated that the soul was immortal and introduced the tekmairesthai doctrine, through which the ideas of anamnesis and prognosis gave birth. We highlight his contributions to medical thought, and especially to neuroscience, which reveal Alcmaeon to be a thinker of considerable originality and one of the greatest philosophers, naturalists, and neuroscientists of all time.

MEASURING THE GRASSROOTS: Puzzles of Cultivating the Grassroots from the Top Down

PubMed Central

Eliasoph, Nina

2014-01-01

Does a participatory, open-ended organizational format inspire creativity and draw on participants' local knowledge? Many nonprofits operate under this assumption, and many of their financial sponsors agree, and therefore demand precise accounts documenting the nonprofits' “participatory” formats. In the U.S. youth civic engagement projects described here, the practice of accounting itself had an effect, regardless of funders' goals. Volunteers devoted more time to documenting just how participatory, open-ended and grassroots they were than they devoted to any other topic. Organizers strenuously tried to avert attention from accounting's importance, but could not avoid it. Volunteers could not reflect on the accounting process, or on the political questions behind it; knowledge of it became a repressed institutional intuition. PMID:25253914

Independent learning: a self-instructional videotape approach in psychiatry.

Golden, K; Furst, E; Sundermann, R; Delk, J; McGill, S

1980-01-01

In response to the increased need to train well-rounded general practitioners within a limited time schedule, the teaching staff developed a self-instructional videotape programme devoted to suicide assessment. This tape, if successful, was to serve as a pilot for a full series of 18 tapes devoted to the assessment and treatment of normally stable patients suffering acute situational stress. In order to avoid the passivity induced by most educational tapes and films, a self-instructional format was adapted to the videotape medium and extensively tested. Students in the experimental group scored significantly higher on three of four measures of effectiveness than did the control group. Students and teachers both strongly supported the production of tapes using a similar format.

Making health care safer: What is the contribution of health psychology?

PubMed

Vincent, Charles; Wearden, Alison; French, David P

2015-11-01

While health care brings great benefits, all treatments, and many investigations, carry some risk. As patients, we should be told of the risks of specific treatments but we are also at risk from failings in the health care system itself. We suggest that, while there are many examples of individual health psychologists who have made important contributions, this has not yet translated into a broader disciplinary engagement. Health psychologists have devoted much more attention to patients and devoted much less attention to the potentially huge impact of studying and intervening with staff, clinical practice, and organizations. We believe that there are considerable opportunities for health psychology to engage more closely with patient safety and, more importantly, that this would be of great benefit to both patients and staff. Statement of contribution What is already known on this subject? While health care brings great benefits, all treatments, and many investigations, carry some risk. Patients are also at risk from failings in the health care system itself. Studies using review of medical records in many countries have found that between 8% and 12% of patients in hospital suffer an unintended harm due to health care. What does this study add? There are many examples of individual psychologists who have made important contributions, but this has not yet translated into a broader disciplinary engagement. There are considerable opportunities for health psychology to engage more closely with patient safety. These include health behaviour change, teamwork, communication after medical error, diagnosis and decision making, organisational culture, and improving compliance with rules and standards. Psychologists providing a clinical service to specialist services in any area could expand their remit from supporting patients to a more general support and engagement with safety and quality initiatives. Health psychologists have models to understand the behaviour of people, and recent developments in changing behaviour should be applicable to health professionals in addition to their patients. © 2015 The British Psychological Society.

PRE-EARTHQUAKES (Processing Russian and European EARTH observations for earthQUAKE precursors Studies) EU-FP7 project is devoted to demonstrate - integrating different observational data, comparing and improving different data analysis methods - how it is possible to progressively increase reliability of short term seismic risk assessment. Three main testing area were selected (Italy, Turkey and Sakhalin ) in order to concentrate observations and integration efforts starting with a learning phase on selected event in the past devoted to identify the most suitable parameters, observations technologies, data analysis algorithms. To this aim events offering major possibilities (variety) of integration were particularly considered - Abruzzo EQ (April 6th 2009 Mw 6.3) for Italy, Elazig EQ (March 8th 2010 Mw 6.1) for Turkey and Nevelsk EQ (August 2nd 2007 Mw 6.2) for Sakhalin - without excluding other significant events occurred during 2011 like the ones of Tōhoku in Japan and Van in Turkey. For these events, different ground (80 radon and 29 spring water stations in Turkey region, 2 magneto-telluric in Italy) and satellite (18 different systems) based observations, 11 data analysis methods, for 7 measured parameters, have been compared and integrated. Results achieved by applying a validation/confutation approach devoted to evaluate the presence/absence of anomalous space-time transients in single and/or integrated observation time-series will be discussed also in comparison with results independently achieved by other authors.

Telerobotic surgery: applications on human patients and training with virtual reality.

PubMed

Rovetta, A; Bejczy, A K; Sala, R

1997-01-01

This paper deals with the developed researches and applications on telerobotic surgery, devoted to human patients and with training by virtual reality. The researches have been developed in cooperation between Telerobotics Laboratory, Department of Mechanics, Politecnico di Milano, Italy, and Automation and Control Section, Jet Propulsion Laboratory, Pasadena, USA. The researches carried to a telesurgery robotic operation on a dummy on 7th July 1993, by means of satellites communications, to a prostatic biopsy on a human patient on 1st September 1995 with optical fibers, to results on time delay effects, to results on virtual reality applications for training on laparoscopy and surgery. The search implied time delay when the control input originated in Politecnico di Milano, Italy. The results were satisfactory, but also pointed out the need for specific new control transformations to ease the operator's or surgeon's visual/mental workload for hand-eye coordination. In the same research, dummy force commands from JPL to Milan were sent, and were echoed immediately back to JPL, measuring the round-trip time of the command signal. This, to some degree, simulates a contact force feedback situation. The results were very surprising; despite the fact that the ISDN calls are closed and "private" calls, the round-trip time exhibited great variations not only between calls but also within the same call. The results proved that telerobotics and telecontrol may be applied to surgery. Time latency variations are caused by features of communication network, of sending and receiving end computer software. The problem and its solution is also an architectural issue, and considerable improvements are possible. Virtual reality in the application of the research is a strong support to training on virtual objects and not on living beings.

To assess potential avoidable hospitalizations of nursing home (NH) residents as a function of the percentage of clinical effort their primary care provider (PCP) devotes to NH practice. Retrospective cohort study. NHs in Texas. Residents newly admitted to long-term NHs in 2006 to 2008 were identified by linking the Minimum Data Set to 100% Texas Medicare claims data (N = 12,249). The care that residents received over successive 6-month periods was measured as a time-dependent covariate. Potentially avoidable hospitalizations and Medicare costs were assessed over 6 to 48 months. Seventy percent of NH residents had a physician as their major PCP, 25% had an advance practice nurse (APN), and 5% had a physician assistant (PA). Physician PCPs who derived less than 20% of their Medicare billings from NH residents cared for 36% of all NH residents. Most NH residents with APN or PA PCPs had providers with 85% or more of Medicare billings generated in NHs. Residents with PCPs who devoted less than 5% of their clinical effort to NH care were at 52% higher risk of potentially avoidable hospitalization than those whose PCPs devoted 85% or more of their clinical effort to NHs (hazard ratio = 1.52, 95% confidence interval = 1.25-1.83) and had $2,179 higher annual Medicare spending, controlling for PCP discipline. The percentage of clinical effort that providers devote to NHs is associated with risk of avoidable hospitalization. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

Crude glycerol is a low-value byproduct which is primarily obtained from the biodiesel production process. Its composition is significantly different from that of pure glycerol. Crude glycerol usually contains various impurities, such as water, methanol, soap, fatty acids, and fatty acid methyl esters. Considerable efforts have been devoted to finding applications for converting crude glycerol into high-value products, such as biofuels, chemicals, polymers, and animal feed, to improve the economic viability of the biodiesel industry and overcome environmental challenges associated with crude glycerol disposal. This article reviews recent advances of biological and chemical technologies for value-added processing of crude glycerol into chemicals and polymers, and provides strategies for addressing production challenges.

Theoretical study on physicochemical properties of curcumin

NASA Astrophysics Data System (ADS)

Shen, Liang; Ji, Hong-Fang

2007-07-01

Curcumin is a yellow-orange pigment, which has attracted considerable attention due to its wide spectrum of biological and pharmacological activities. In spite of much effort devoted on curcumin, there still exist some open questions concerning its fundamental physicochemical properties. The present study suggests that the DFT and TD-DFT calculations are useful to answer these questions. Firstly, the thermodynamic as well as spectral parameters support that curcumin exists predominantly in enol form in solution. Secondly, the calculated absorption spectra of curcumin anions provides direct evidence that the lowest p Ka of curcumin corresponds to the dissociation of enolic proton, which not only reconciles the controversy on this topic, but also has important implications on the proton-transfer/dissociation-associated radical-scavenging mechanisms of curcumin.

Anorectal melanoma is an uncommon and aggressive mucosal melanocytic malignancy. Due to its rarity, the pre-operative diagnosis remains difficult. The first symptoms are non-specific such as anal bleeding, anal mass or pain. Although anorectal melanoma carries a poor prognosis; optimal therapeutics strategies are unclear. Surgical resection remains the mainstay of treatment. The optimal surgical procedure for primary tumours is controversial and can vary from wide local excision or endoscopic mucosal resection (EMR) to an abdomino-perineal resection. A high degree of uncertainly exists regarding the benefit of radiation therapy or chemotherapy. The treatment of advanced melanoma is evolving rapidly with better understanding of the disease biology and immunology. Considerable effort has been devoted to the identification of molecular determinants of response to target therapies and immunotherapy. PMID:29492238

Low-gravity impact experiments: Progress toward a facility definition

NASA Technical Reports Server (NTRS)

Cintala, M. J.

1986-01-01

Innumerable efforts were made to understand the cratering process and its ramifications in terms of planetary observations, during which the role of gravity has often come into question. Well known facilities and experiments both were devoted in many cases to unraveling the contribution of gravitational acceleration to cratering mechanisms. Included among these are the explosion experiments in low gravity aircraft, the drop platform experiments, and the high gravity centrifuge experiments. Considerable insight into the effects of gravity was gained. Most investigations were confined to terrestrial laboratories. It is in this light that the Space Station is being examined as a vehicle with the potential to support otherwise impractical impact experiments. The results of studies performed by members of the planetary cratering community are summarized.

Pharmaceutical advertisements in medical journals received in a medical clinic: are we having "too much of a good thing"?

Lohiya, Sapna

2005-05-01

A convenience sample of all medical journals found in a medical clinic was reviewed for pharmaceutical advertisements. Ads were present in 25 (96%) of the 26 journals. Ad space varied from 0-34% (mean 12) in research, and 9-48% (mean: 36) in nonresearch journals. In 23 (88%) journals, individual ads consisted of more than one page. Colorful glossy insert-ads, of up to nine pages, were seen in 18 (69%) journals. Six (23%) journals contained more advertising than editorial pages. Many ads were longer than the longest article in that journal. Medical journals devote considerable space to pharmaceutical ads. Excessive pharmaceutical advertising may bias the journals' owners and readers and may be distracting and annoying.

[Melancholy between medicine and religion: from a pathology of religious behaviour to a pathological practice of religion].

PubMed

Crignon-De Oliveira, Claire

2006-01-01

By proposing in 1621 to create the completely separate category of religious melancholy, Burton inaugurated the medicalisation of religious controversy which developed considerably after the English Civil Wars. While religious melancholy was a useful critical and polemical weapon for all the defenders of Anglican orthodoxy trying to present fanatics (enthusiasts) and atheists as sick people suffering from a humoural imbalance, it finally came in the early 18th century to designate a certain way of practising religion or alternatively the behaviour of those who devoted their lives to religion. The present article examines this transition from a medical interpretation of nonconformist religious behaviour to the identification of a pathological practice of religion.

Enhancing academic achievement for children with Attention-Deficit Hyperactivity Disorder: evidence from school-based intervention research.

Jitendra, Asha K; Dupaul, George J; Someki, Fumio; Tresco, Katy E

2008-01-01

Although children with Attention-Deficit Hyperactivity Disorder (ADHD) exhibit significant academic difficulties in school settings, considerably less attention is devoted to remediating their academic problems when compared to behavioral and social difficulties. The purpose of this article is to review empirically supported academic interventions for children with ADHD. Specific evidence-based academic interventions are described under the categories of reading and mathematics, with examples that illustrate teacher-mediated interventions focusing on basic skills (e.g., phonological awareness in reading, mathematics computation) and higher-level cognitive skills (e.g., collaborative strategic reading, CSR; schema-based instruction, SBI). Finally, implications for educational practice and directions for future research on school-based academic interventions for students with ADHD are discussed.

The Expeditionary Test Set - A fresh approach to automatic testing

NASA Astrophysics Data System (ADS)

Williams, D. L.; Austin, W. J.

This paper discusses the key design decisions and tradeoffs leading from the conceptual stage to the production version of the Expeditionary Test Set (ETS) for the USMC. This included a ten-month feasibility study program funded by the Naval Air Systems Command which culminated in the successful demonstration of a working tester model. The demonstration of the test set was preceded by a substantial re-thinking of conventional ATE test methods. Considerable discussion is devoted to the impact of test philosophy, both on the test set design and the overall effectiveness of avionic testing. Major architectural features of the test set are presented in some detail, and the many areas which break from traditional ATE design are emphasized.

Abnormal ovarian cancer screening test result: women's informational, psychological and practical needs.

2007-01-01

Considerable effort has been devoted to the identification of cost-effective approaches to screening for ovarian cancer (OC). Transvaginal ultrasound (TVS) is one such screening approach. Approximately 5-7% of routine TVS screening tests yield abnormal results. Some women experience significant distress after receipt of an abnormal TVS screening test. Four focus groups provided in-depth, qualitative data regarding the informational, psychological, and practical needs of women after the receipt of an abnormal TVS result. Through question and content analytic procedures, we identified four themes: anticipation, emotional response, role of the screening technician, and impact of prior cancer experiences. Results provide initial guidance toward development of interventions to promote adaptive responses after receipt of an abnormal cancer screening test result.

Relationships between High School Chemistry Students' Perceptions of a Constructivist Learning Environment and their STEM Career Expectations

NASA Astrophysics Data System (ADS)

Wild, Andrew

2015-09-01

Considerable attention has been devoted to factors affecting the persistence of women and historically underrepresented ethnic groups in their science education trajectories. The literature has focused more on structural factors that affect longitudinal outcomes rather than classroom experiences. This exploratory survey study described relationships among high school chemistry students' perceptions of a constructivist learning environment (CLE) and STEM career expectations. The sample included 693 students from 7 public high schools within the San Francisco Bay Area. Students' perceptions of a CLE predicted their expectations of entering a science career, but not engineering, computer, health, or mathematics-related careers. When all groups of students perceived the learning environment as more constructivist, they were more likely to expect science careers.

Establishing a Conceptual Foundation for Addressing Challenges Facing Food-Energy-Water Management

NASA Astrophysics Data System (ADS)

Goldsby, M.; Padowski, J.; Katz, S.; Brady, M.; Hampton, S. E.

2017-12-01

Ensuring the security of food, energy and water in the face of a changing environment is a top societal priority. In order to make sound policy decisions aimed at meeting those needs, policy-makers need decision-relevant information. As such, considerable effort and resources have recently been devoted to investigating the Food-Energy-Water (FEW) Nexus in order to better provide that information. However, despite the increased research activity into FEW systems and FEW problems, little attention has been devoted to the fundamental conceptual issues underlying contemporary FEW systems. Consequently, this inattention has led to conceptual confusion about what is and what is not a FEW system. This project aims to fill that lacuna in order to better facilitate the FEW research agenda. Toward that end, we identify three features that distinguish FEW problems from other resource management problems: (1) the production and management of the resources in each sector of a FEW system is specialized to its own sector; (2) interdependencies exist between sectors such that overproduction in one sector, for example, may have impacts on other sectors; and (3) there are real limits to FEW resource availability as well as limits on the ability to transact across sector boundaries. We contend that once armed with this distinction, one can model the stocks and flows of FEW capital in a conceptually rigorous way that may lead to operational innovations of FEW management.

[Providing regular relief; considerations for palliative care in the Netherlands].

PubMed

Crul, B J; van Weel, C

2001-10-20

Over the last few decades the attention devoted to the palliative aspects of medicine, particularly those in hospital care, has declined due to the emphasis on medical technology. In Anglo-Saxon countries a review of this development resulted in structured palliative care that benefited terminally ill patients with a progressive fatal disease, especially cancer patients. Due to increasing national and international criticism of both the practice of euthanasia (assumed to be too liberal) and the lack of attention devoted to structured palliative care in the Netherlands, the Dutch government decided to improve the structure of palliative care. The government's viewpoint is based on the assumption that good palliative care that includes adequate pain control benefits patient care and might eventually lead to fewer requests for euthanasia. The improvements to palliative care should be realised by means of improvements in the structure, training and knowledge. Six academic medical clusters have been designated as Centres for the Development of Palliative Care (Dutch acronym: COPZ) for a 5-year period. Each COPZ must develop the various aspects needed to improve palliative care within the region it serves and ensure that its activities are carefully coordinated with those in the other centres. Research will focus on measuring the efficacy of palliative care as well as ethical and epidemiological aspects. A government committee will assess the appropriateness of the activities undertaken by each of the centres.

Current trends in Canadian health care: myths and misconceptions in health economics.

PubMed

Coyte, P C

1990-01-01

This paper is concerned with the economic aspects of the trends in Canadian health care. Various myths and misconceptions abound regarding the applicability of economics to behaviour in the health care industry as well as to the interpretation of recent trends. Both issues are examined in this paper. While most discussions regarding health care trends begin with the share of health expenditures in Gross National Product, I propose an alternative share that adjusts for cyclical variations in both unemployment and labour force participation. Using this measure, I show that the "real" growth of resources devoted to the health care industry is much larger than that obtained with conventional measures, and that the difference in growth rates between Canada and the U.S. is narrowed considerably. The paper outlines and disputes the validity of three public health policy propositions. First, it is not empirically valid to say that the introduction of universal medical insurance in Canada successfully contained the growth in the share of society's resources devoted to the health care industry. Second, it is not correct to argue that the change in the federal funding for hospital and medical care in 1977 was a "fiscal non-event". And finally, the proposed "equity" funding formula for Ontario hospitals is unlikely to contain costs and will potentially skew hospitals towards the provision of complex forms of care instead of cost-effective community-based alternatives.

On The Aerodynamic Heating Of Vega Launcher: Compressible Chimera Navier-Stokes Simulation With Complex Surfaces

NASA Astrophysics Data System (ADS)

Di Mascio, A.; Zaghi, S.; Muscari, R.; Broglia, R.; Cavallini, E.; Favini, B.; Scaccia, A.

2011-05-01

The results of accurate compressible Navier-Stokes simulations of aerodynamic heating of the Vega launcher are presented. Three selected steady conditions of the Vega mission profile are considered: the first corresponding to the altitude of 18 km, the second to 25 km and the last to 33 km. The numerical code is based on the Favre- Average Navier-Stokes equations; the turbulent model chosen for closure is the one-equation model by Spalart- Allmaras. The equations are discretized by a finite volume approach, that can handle block-structured meshes with partial overlap (“Chimera” grid-overlapping technique). The isothermal boundary condition has been applied to the lancher wall. Particular care was devoted to the construction of the discrete model; indeed, the launcher is equipped with many protrusions and geometrical peculiarities (as antennas, raceways, inter-stage connection flanges and retrorockets) that are expected to affect considerably the local thermal flow-field and the level of heat fluxes, because the flow have to undergo strong variation in space; con- sequently, special attention was devoted to the definition of a tailored mesh, capable of catching local details of the aerothermal flow field (shocks, expansion fans, boundary layer, etc..). The computed results are reported together with uncertainty and actual convergence order, that were estimated by the standard procedures suggested by AIAA [Ame98].

The incidence of high medical expenses by health status in seven developed countries.

PubMed

Baird, Katherine Elizabeth

2016-01-01

Health care policy seeks to ensure that citizens are protected from the financial risk associated with needing health care. Yet rising health care costs in many countries are leading to a greater reliance on out-of-pocket (OOP) measures. This paper uses 2010 household survey data from seven countries to measure and compare the burden OOP expenses place on individuals. It compares countries based on the extent to which citizens with health problems devote a large share of their income to OOP expenses. The paper finds that in all countries but France, and to a lesser extent Slovenia, citizens with health problems face considerably higher medical costs than do those without. As many as one-quarter of less healthy citizens in the US, Poland, Russia and Israel devote a large share of their income to OOP expenses. The paper also finds a strong cross-national correlation between the degree to which citizens face high OOP expenses, and the disparities in OOP expenses between those with and without health problems. The levels of high OOP spending uncovered, and their inequitable impact on those with health problems in the seven countries, underscore the potential for OOP measures to undermine core objectives of health care systems, including those of equitable financing, equal access, and improved health among the population.

Performance enhancement in a semi-autonomous confined microsociety

NASA Technical Reports Server (NTRS)

Brady, J. V.; Bernstein, D. J.; Foltin, R. W.; Nellis, M. J.

1988-01-01

Research in a continuously programmed human experimental laboratory has been directed toward identifying, defining, and expanding generalized knowledge concerning motivational factors within the structure of human behavioral repertoires that maintain and enhance performance. Participants (in groups of three) engaged in a series of repetitive work activities (e.g., word sorting and rug-hooking) for extended periods each day, while living continuously in a residential laboratory. Other parts of the day were spent either interacting socially with other participants or engaging in individual recreational activities. The percentage of time devoted to the various work tasks provided the basis for selecting one activity that occurred with high frequency and one with low frequency. Performance of the low-frequency activity was then required in order to gain access to the high-frequency activity. Under such contingencies, time devoted to the original low-frequency activity increased greatly, and the participants consistently did more than the required amount of the low-frequency work than was necessary to restore access to the restricted work activity. The theoretical significance of these findings resides in the clear demonstration that a time-based model of value applies as well to the enhancement of work-like performance as it does to voluntarily selected or preferred recreational activities.

Television advertising of foodstuffs potentially detrimental to oral health--a content analysis and comparison of children's and primetime broadcasts.

PubMed

Chestnutt, I G; Ashraf, F J

2002-06-01

The study aimed to examine the nature, content and duration of advertisements broadcast during children's television; determine the proportion of advertisements promoting food; identify the potential of the food advertised to be detrimental to oral health; and to compare the nature and content of advertisements aimed at children with those transmitted during evening 'primetime' television. Children's and primetime television, broadcast on a main independent terrestrial channel in South Wales were video recorded, 237 and 42 hours being analysed in total. Analysis of the recording resulted in a total of 3,236 commercials, of which 2,345 were broadcast during children's television and 891 in primetime. During children's TV, 62.5% of advertising time was devoted to foodstuffs, significantly greater (P< 0.001) than the 18.4% of time spent advertising foods during primetime. Of the time spent advertising foods, during children's television 73.4% was devoted to products deemed potentially detrimental to oral health (primarily high in sugar), compared to 18.6% similarly categorised during evening television. Commercials for products which have the potential to adversely affect oral health constitute a large proportion of advertising time during children's television. Current codes of the Independent Television Commission governing advertising directed at children should be reviewed.

Energy-time entanglement, elements of reality, and local realism

NASA Astrophysics Data System (ADS)

Jogenfors, Jonathan; Larsson, Jan-Åke

2014-10-01

The Franson interferometer, proposed in 1989 (Franson 1989 Phys. Rev. Lett. 62 2205-08), beautifully shows the counter-intuitive nature of light. The quantum description predicts sinusoidal interference for specific outcomes of the experiment, and these predictions can be verified in experiment. In the spirit of Einstein, Podolsky, and Rosen it is possible to ask if the quantum-mechanical description (of this setup) can be considered complete. This question will be answered in detail in this paper, by delineating the quite complicated relation between energy-time entanglement experiments and Einstein-Podolsky-Rosen (EPR) elements of reality. The mentioned sinusoidal interference pattern is the same as that giving a violation in the usual Bell experiment. Even so, depending on the precise requirements made on the local realist model, this can imply (a) no violation, (b) smaller violation than usual, or (c) full violation of the appropriate statistical bound. Alternatives include (a) using only the measurement outcomes as EPR elements of reality, (b) using the emission time as EPR element of reality, (c) using path realism, or (d) using a modified setup. This paper discusses the nature of these alternatives and how to choose between them. The subtleties of this discussion needs to be taken into account when designing and setting up experiments intended to test local realism. Furthermore, these considerations are also important for quantum communication, for example in Bell-inequality-based quantum cryptography, especially when aiming for device independence. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘50 years of Bell’s theorem’.

A problem with inverse time for a singularly perturbed integro-differential equation with diagonal degeneration of the kernel of high order

NASA Astrophysics Data System (ADS)

Bobodzhanov, A. A.; Safonov, V. F.

2016-04-01

We consider an algorithm for constructing asymptotic solutions regularized in the sense of Lomov (see [1], [2]). We show that such problems can be reduced to integro-differential equations with inverse time. But in contrast to known papers devoted to this topic (see, for example, [3]), in this paper we study a fundamentally new case, which is characterized by the absence, in the differential part, of a linear operator that isolates, in the asymptotics of the solution, constituents described by boundary functions and by the fact that the integral operator has kernel with diagonal degeneration of high order. Furthermore, the spectrum of the regularization operator A(t) (see below) may contain purely imaginary eigenvalues, which causes difficulties in the application of the methods of construction of asymptotic solutions proposed in the monograph [3]. Based on an analysis of the principal term of the asymptotics, we isolate a class of inhomogeneities and initial data for which the exact solution of the original problem tends to the limit solution (as \\varepsilon\\to+0) on the entire time interval under consideration, also including a boundary-layer zone (that is, we solve the so-called initialization problem). The paper is of a theoretical nature and is designed to lead to a greater understanding of the problems in the theory of singular perturbations. There may be applications in various applied areas where models described by integro-differential equations are used (for example, in elasticity theory, the theory of electrical circuits, and so on).

The Central Nervous Connections Involved in the Vomiting Reflex

NASA Technical Reports Server (NTRS)

Brizzee, K. R.; Mehler, W. R.

1986-01-01

The vomiting reflex may be elicited by a number of different types or classes of stimuli involving many varieties of receptor structures and considerable diversity in afferent pathways and central connections. Central relay or mediating structures thus may vary widely according to the type of initial emetic stimulus. The emetic circuits which have been most completely delineated to date are probably those in which the Chemoreceptor Trigger Zone (CTZ) in the Area Postrema (AP) functions as a key mediating structure. Even in this system, however, there are large gaps in our knowledge of the nerve tracts and central nervous connections involved. Knowledge of most other emetic circuits subserving the emetic reflex resulting from many diverse types of stimuli such, for example, as emotional stress (e.g. psychogenic vomiting, Wruble et al. 1982), pain (e.g. testicular trauma), and chemical or mechanical irritation of the gastrointestinal tract or urinary tract is quite incomplete at this time, thus precluding any very adequate description of their central connections at present. One physiological system, however, which has received considerable attention recently in relation to the vomiting reflex elicited by motion stimuli is the vestibular system. Due to the paucity of data on central nervous connections of several or the non-vestibular types of emetic stimuli cited above, we will devote most of our attention in this brief review to the central connections of the vestibular system which seem likely to be involved in the vomiting response to motion stimuli. However, the latter part of the review will be concerned with the concept of the reticular vomiting centre in relation to the ParviCellular Reticular Formation (PCRF), and will thus probably pertain to all of the many classes of emetic stimuli since it will address the question of the final common emetic pathway.

Studying the dynamics of interbeat interval time series of healthy and congestive heart failure subjects using scale based symbolic entropy analysis

Considerable interest has been devoted for developing a deeper understanding of the dynamics of healthy biological systems and how these dynamics are affected due to aging and disease. Entropy based complexity measures have widely been used for quantifying the dynamics of physical and biological systems. These techniques have provided valuable information leading to a fuller understanding of the dynamics of these systems and underlying stimuli that are responsible for anomalous behavior. The single scale based traditional entropy measures yielded contradictory results about the dynamics of real world time series data of healthy and pathological subjects. Recently the multiscale entropy (MSE) algorithm was introduced for precise description of the complexity of biological signals, which was used in numerous fields since its inception. The original MSE quantified the complexity of coarse-grained time series using sample entropy. The original MSE may be unreliable for short signals because the length of the coarse-grained time series decreases with increasing scaling factor τ, however, MSE works well for long signals. To overcome the drawback of original MSE, various variants of this method have been proposed for evaluating complexity efficiently. In this study, we have proposed multiscale normalized corrected Shannon entropy (MNCSE), in which instead of using sample entropy, symbolic entropy measure NCSE has been used as an entropy estimate. The results of the study are compared with traditional MSE. The effectiveness of the proposed approach is demonstrated using noise signals as well as interbeat interval signals from healthy and pathological subjects. The preliminary results of the study indicate that MNCSE values are more stable and reliable than original MSE values. The results show that MNCSE based features lead to higher classification accuracies in comparison with the MSE based features. PMID:29771977

Considerable interest has been devoted for developing a deeper understanding of the dynamics of healthy biological systems and how these dynamics are affected due to aging and disease. Entropy based complexity measures have widely been used for quantifying the dynamics of physical and biological systems. These techniques have provided valuable information leading to a fuller understanding of the dynamics of these systems and underlying stimuli that are responsible for anomalous behavior. The single scale based traditional entropy measures yielded contradictory results about the dynamics of real world time series data of healthy and pathological subjects. Recently the multiscale entropy (MSE) algorithm was introduced for precise description of the complexity of biological signals, which was used in numerous fields since its inception. The original MSE quantified the complexity of coarse-grained time series using sample entropy.

1994-11-01

To assess by self-reported participation in vigorous physical activity, the quantity and quality of school physical education, team sports, and television watching among 11,631 American high school students. Of all students in grades 9 through 12, 37% reported engaging in 20 minutes of vigorous physical activity three or more times per week. Participation in vigorous physical activity was higher among boys than girls (P < .01) and higher among white students than among those of other races and ethnic groups (P < .01). Overall, 43.7% of boys and 52% of girls reported that they were not enrolled in physical education classes. Of the students who reported attending physical education class during the past 2 weeks, 33.2% reported exercising 20 minutes or more in physical education class three to five times per week. In contrast, rates of participation in varsity and junior varsity sports remained constant across grade levels, but participation in recreational physical activity programs showed a lesser magnitude and also decreased with advancing grade. More than 70% of students reported spending at least 1 hour watching television each school day, and more than 35% reported watching television 3 hours or more each school day. Participation in vigorous physical activity and physical education class time devoted to physical activity are substantially below the goals set in Healthy People 2000. As students move toward graduation, we observed disturbing declines in participation in community recreation programs and overall vigorous activity. Students appear to spend considerably more time watching television than participating in physical activity. Public health efforts should focus on increasing the physical activity levels of our youth to enhance their current well-being and to reduce the risks of future chronic disease.

On the acquisition and representation of procedural knowledge

NASA Technical Reports Server (NTRS)

Saito, T.; Ortiz, C.; Loftin, R. B.

1992-01-01

Historically knowledge acquisition has proven to be one of the greatest barriers to the development of intelligent systems. Current practice generally requires lengthy interactions between the expert whose knowledge is to be captured and the knowledge engineer whose responsibility is to acquire and represent knowledge in a useful form. Although much research has been devoted to the development of methodologies and computer software to aid in the capture and representation of some of some types of knowledge, little attention has been devoted to procedural knowledge. NASA personnel frequently perform tasks that are primarily procedural in nature. Previous work is reviewed in the field of knowledge acquisition and then focus on knowledge acquisition for procedural tasks with special attention devoted to the Navy's VISTA tool. The design and development is described of a system for the acquisition and representation of procedural knowledge-TARGET (Task Analysis and Rule Generation Tool). TARGET is intended as a tool that permits experts to visually describe procedural tasks and as a common medium for knowledge refinement by the expert and knowledge engineer. The system is designed to represent the acquired knowledge in the form of production rules. Systems such as TARGET have the potential to profoundly reduce the time, difficulties, and costs of developing knowledge-based systems for the performance of procedural tasks.

Busting myths and building resilience: Practices and approaches that go beyond mere plan development.

PubMed

Armour, Mark

Dwight D. Eisenhower is often quoted as saying: 'In battle, plans are useless but planning is indispensable'. How many in the business continuity profession actually think about that statement and what it really means? Audit, compliance and regulatory requirements as well as the expectations of executives and business leaders result in an inordinate amount of time and effort devoted to plan development with scant attention paid to actual planning. Practitioners need to realise that the value of the plans they develop is not derived from the finished documents but from the work devoted to completing them. Experience and practice win out above detailed plans. One need look no further than Eisenhower's D-Day invasion of Normandy as evidence. Practitioners need to learn how to be better at instituting preparedness and not simply developing better plans.

Microneurosurgery is Professor Yaşargil's legacy. Its impact on patient outcomes, surgeons' abilities, the field of neurosurgery in particular, and the art of surgery in general is great, profound, and everlasting. Professor Yaşargil led a revolution that has transformed neurosurgery into the fine art we practice today. His ingenuity, devotion, energy, and masterful technique have made his contributions so salient that they have earned him recognition as Neurosurgery's Man of the Century. It has been an honor, a great opportunity, and a phenomenal experience to spend the last 5 years with him at the University of Arkansas for Medical Sciences in Little Rock. There, he represents the very best in knowledge, expertise, dexterity, and, above all, devotion to advancing the field of neurosurgery. Most enjoyable have been his stimulating intellect and inspiring vision.

Drawing disability in Japanese manga: visual politics, embodied masculinity, and wheelchair basketball in Inoue Takehiko's REAL.

PubMed

Wood, Andrea

2013-12-01

This work explores disability in the cultural context of contemporary Japanese comics. In contrast to Western comics, Japanese manga have permeated the social fabric of Japan to the extent that vast numbers of people read manga on a daily basis. It has, in fact, become such a popular medium for visual communication that the Japanese government and education systems utilize manga as a social acculturation and teaching tool. This multibillion dollar industry is incredibly diverse, and one particularly popular genre is sports manga. However, Inoue Takehiko's award-winning manga series REAL departs from more conventional sports manga, which typically focus on able-bodied characters with sometimes exaggerated superhuman physical abilities, by adopting a more realistic approach to the world of wheelchair basketball and the people who play it. At the same time REAL explores cultural attitudes toward disability in Japanese culture-where disability is at times rendered "invisible" either through accessibility problems or lingering associations of disability and shame. It is therefore extremely significant that manga, a visual medium, is rendering disability visible-the ultimate movement from margin to center. REAL devotes considerable attention to realistically illustrating the lived experiences of its characters both on and off the court. Consequently, the series not only educates readers about wheelchair basketball but also provides compelling insight into Japanese cultural notions about masculinity, family, responsibility, and identity. The basketball players-at first marginalized by their disability-join together in the unity of a sport typically characterized by its "abledness."

First clinical use of stereotaxy in humans: the key role of x-ray localization discovered by Gaston Contremoulins.

PubMed

Bourdillon, Pierre; Apra, Caroline; Lévêque, Marc

2018-03-01

Although attempts to develop stereotactic approaches to intracranial surgery started in the late 19th century with Dittmar, Zernov, and more famously, Horsley and Clarke, widespread use of the technique for human brain surgery started in the second part of the 20th century. Remarkably, a significant similar surgical procedure had already been performed in the late 19th century by Gaston Contremoulins in France and has remained unknown. Contremoulins used the principles of modern stereotaxy in association with radiography for the first time, allowing the successful removal of intracranial bullets in 2 patients. This surgical premiere, greatly acknowledged in the popular French newspaper L'Illustration in 1897, received little scientific or governmental interest at the time, as it emanated from a young self-taught scientist without official medical education. This surgical innovation was only made possible financially by popular crowdfunding and, despite widespread military use during World War I, with 37,780 patients having benefited from this technique for intra- or extracranial foreign bodies, it never attracted academic or neurosurgical consideration. The authors of this paper describe the historical context of stereotactic developments and the personal history of Contremoulins, who worked in the department of experimental physiology of the French Academy of Sciences led by Étienne-Jules Marey in Paris, and later devoted himself to radiography and radioprotection. The authors also give precise information about his original stereotactic tool "the bullet finder" ("le chercheur de projectiles") and its key concepts.

Current status of the East Sea Ecosystem in a changing world

2017-12-01

The East/Japan Sea (hereafter the East Sea) is changing quickly. Warming and structural changes in the East Sea have been reported by CREAMS, an acronym of ″Circulation Research of the East Asian Marginal Seas″, which began in 1993 as an international research program to understand the water mass structure and circulation in the East Sea (Kim and Kim, 1996; Kim, 1997; Kim et al., 2001, 2002). A subsequent research program of the EAST-I, an acronym of ″the East Asian Seas Time-series″, was launched by PICES (North Pacific Marine Science Organization) and financially supported by the Korean government, allowing us to deepen our knowledge about rapidly changing processes in the East Sea (Chang et al., 2010). Although there has been considerable progress in developing a mechanistic understanding of the East Sea ecosystem responses to disturbances, more comprehensive studies are needed to address the impacts of the frequency and intensity of disturbances on marine ecosystems. The most important question of the research has been: how do environmental changes affect structural and functional biodiversity? Recently launched research on ″Long-term change of structure and function in marine ecosystems of Korea″, which has been supported by the Korean government since 2011, has given an unprecedented insight into the ecosystem dynamics in the East Sea. It therefore seems an appropriate time to devote a special issue to the topic of ″Current status of the East Sea ecosystem in a changing world″.

The performance of functional polymer nanomaterials is a vigorously discussed topic in polymer science. We devoted ourselves to investigating polymer nanomaterials based on near-infrared (NIR) fluorescence imaging and polymer prodrug in this study. Aza-boron dipyrromethene (BODIPY) is an important organic dye, having characteristics such as environmental resistance, light resistance, high molar extinction coefficient, and fluorescence quantum yield. We incorporated it into our target monomer, which can be polymerized without changing its parent structure in a polar solvent and copolymerized with water-soluble monomer to improve the solubility of the dye in an aqueous solution. At the same time, the hydrophobic drug camptothecin (CPT) was designed as a prodrug monomer, and the polymeric nanoparticles (NPs) with NIR fluorescence imaging and prodrug were synthesized in situ in reversible addition-fragmentation chain transfer (RAFT)-mediated aqueous dispersion polymerization. The dynamic light scattering (DLS) and transmission electron microscopy (TEM) revealed the final uniform size of the dual-functional polymeric NPs morphology. The dual-functional polymeric NPs had a strong absorption and emission signal in the NIR region (>650 nm) based on the fluorescence tests. In consideration of the long-term biological toxicity, confocal laser scanning microscopy (CLSM) results indicated that the dual-functional NPs with controlled drug content exhibited effective capability of killing HeLa cells. In addition, in vivo imaging of the dual-functional NPs was observed in real time, and the fluorescent signals clearly demonstrated the dynamic process of prodrug transfer.

A Lifetime's Adventure in Extracellular K+ Regulation: The Scottish Connection.

PubMed

Brown, Angus M

2017-09-01

In a career that has spanned 45 years and shows no signs of slowing down, Dr Bruce Ransom has devoted considerable time and energy to studying regulation of interstitial K + . When Bruce commenced his studies in 1969 virtually nothing was known of the functions of glial cells, but Bruce's research contributed to the physiological assignation of function to mammalian astrocytes, namely interstitial K + buffering. The experiments that I describe in this review concern the response of the membrane potential (Em) of in vivo cat cortical astrocytes to changes in [K + ] o , an experimental manoeuvre that was achieved in two different ways. The first involved recording the Em of an astrocyte while the initial aCSF was switched to one with different K + , whereas in the second series of experiments the cortex was stimulated and the response of the astrocyte Em to the K + released from neighbouring neurons was recorded. The astrocytes responded in a qualitatively predictable manner, but quantitatively the changes were not as predicted by the Nernst equation. Elevations in interstitial K + are not sustained and K + returns to baseline rapidly due to the buffering capacity of astrocytes, a phenomenon studied by Bruce, and his son Chris, published 27 years after Bruce's initial publications. Thus, a lifetime spent investigating K + buffering has seen enormous advances in glial research, from the time cells were identified as 'presumed' glial cells or 'silent cells', to the present day, where glial cells are recognised as contributing to every important physiological brain function.

The scope of problems concerning the disabled still remains a constantly up-to-date social issue, which requires current scientific analysis. In concern for the disabled, the problem of physical activity through their participation in tourism occupies an important position. The studies concern the disabled from three regions: Lublin, Białystok and Rzeszów, where there occurs the highest intensity of the phenomenon of disability. The recognition of interests and needs manifested by the disabled from the eastern regions of Poland concerning the use of forms of tourism during leisure time. The method of a diagnostic survey and questionnaire technique were applied. A total number of 750 disabled were examined. The study showed that the majority of the disabled spend their free time devoted to tourist activity according to their needs. The main forms of participation in tourism are sightseeing tours and package holidays, and the respondents would like most to participate in rehabilitation camps and sightseeing tours. A considerable variation was observed in the participation in forms of tourism among the disabled from individual regions. The disabled who do not wish to participate in sports-recreation and tourist activities, and for whom their state of health is the main barrier, require special interest. A relatively large variation of tourism forms used by the disabled in individual regions indicate the need for an exchange of experiences between specialist facilities taking care of the disabled.

Simulating nonlinear steady-state traveling waves on the falling liquid film entrained by a gas flow

NASA Astrophysics Data System (ADS)

Tsvelodub, O. Yu; Bocharov, A. A.

2017-09-01

The article is devoted to the simulation of nonlinear waves on a liquid film flowing under gravity in the known stress field at the interface. The paper studies nonlinear waves on a liquid film, flowing under the action of gravity in a known stress field at the interface. In the case of small Reynolds numbers the problem is reduced to the consideration of solutions of the nonlinear integral-differential equation for film thickness deviation from the undisturbed level. The periodic and soliton steady-state traveling solutions of this equation have been numerically found. The analysis of branching of new families of steady-state traveling solutions has been performed. In particular, it is shown that this model equation has solutions in the form of solitons-humps.

Delivery methods for site-specific nucleases: Achieving the full potential of therapeutic gene editing.

PubMed

Liu, Jia; Shui, Sai-Lan

2016-12-28

The advent of site-specific nucleases, particularly CRISPR/Cas9, provides researchers with the unprecedented ability to manipulate genomic sequences. These nucleases are used to create model cell lines, engineer metabolic pathways, produce transgenic animals and plants, perform genome-wide functional screen and, most importantly, treat human diseases that are difficult to tackle by traditional medications. Considerable efforts have been devoted to improving the efficiency and specificity of nucleases for clinical applications. However, safe and efficient delivery methods remain the major obstacle for therapeutic gene editing. In this review, we summarize the recent progress on nuclease delivery methods, highlight their impact on the outcomes of gene editing and discuss the potential of different delivery approaches for therapeutic gene editing.

Wu, Chi-Chao

2000-01-01

The general objective of this project is to provide a comprehensive ultraviolet spectral atlas of stars based on the data in the IUE Final Archive. The data have been uniformly processed by the IUE NEWSIPS pipeline system. The NEWSIPS gives an improved signal to noise ratio for the data that will be especially beneficial to low signal portions of the spectra; and it also gives more accurate fluxes for stars by adopting the latest absolute calibration and measured instrument parameters. Our new atlas, therefore, provides more uniform and accurate data than the version previously published. In addition, considerable efforts were devoted to obtain reliable spectral types, V,B-V, and E(B-V). Our goal is to provide the information which can be used with reasonable confidence by scientists.

Hill, Ryan T

2015-01-01

The unique optical properties of plasmon resonant nanostructures enable exploration of nanoscale environments using relatively simple optical characterization techniques. For this reason, the field of plasmonics continues to garner the attention of the biosensing community. Biosensors based on propagating surface plasmon resonances (SPRs) in films are the most well-recognized plasmonic biosensors, but there is great potential for the new, developing technologies to surpass the robustness and popularity of film-based SPR sensing. This review surveys the current plasmonic biosensor landscape with emphasis on the basic operating principles of each plasmonic sensing technique and the practical considerations when developing a sensing platform with the various techniques. The 'gold standard' film SPR technique is reviewed briefly, but special emphasis is devoted to the up-and-coming localized surface plasmon resonance and plasmonically coupled sensor technology. © 2014 Wiley Periodicals, Inc.

Space Station and the life sciences

1983-01-01

Previous fundamental research in space life sciences is examined, and consideration is devoted to studies relevant to Space Station activities. Microgravity causes weight loss, hemoconcentration, and orthostatic intolerance when astronauts returns to earth. Losses in bone density, bone calcium, and muscle nitrogen have also been observed, together with cardiovascular deconditioning, fluid-electrolyte metabolism alteration, and space sickness. Experiments have been performed with plants, bacteria, fungi, protozoa, tissue cultures, invertebrate species, and with nonhuman vertebrates, showing little effect on simple cell functions. The Spacelab first flight will feature seven life science experiments and the second flight, two. Further studies will be performed on later flights. Continued life science studies to optimize human performance in space are necessary for the efficient operation of a Space Station and the assembly of large space structures, particularly in interaction with automated machinery.

Opportunities and choice in a new vector era

NASA Astrophysics Data System (ADS)

Nowak, A.

2014-06-01

This work discusses the significant changes in computing landscape related to the progression of Moore's Law, and the implications on scientific computing. Particular attention is devoted to the High Energy Physics domain (HEP), which has always made good use of threading, but levels of parallelism closer to the hardware were often left underutilized. Findings of the CERN openlab Platform Competence Center are reported in the context of expanding "performance dimensions", and especially the resurgence of vectors. These suggest that data oriented designs are feasible in HEP and have considerable potential for performance improvements on multiple levels, but will rarely trump algorithmic enhancements. Finally, an analysis of upcoming hardware and software technologies identifies heterogeneity as a major challenge for software, which will require more emphasis on scalable, efficient design.

The experience with dynamic renal scintigraphy has shown its high informative value and safety in evaluating the degree of intrarenal urine outflow disorders. However, failure to make an objective assessment of ureteral patency considerably limits its study. The set of studies, which is given in this paper, is devoted to precisely this, highly urgent, problem. The authors have developed an original procedure for diagnosing impaired urine outflow along the ureters during dynamic renal scintigraphy. The visual and digital characteristics of normal and impaired urine outflow in the supravesical segment are defined. The criteria characterizing severe impairments of renal urine derivation along the ureters are denoted. Risk factors for urine outflow disorders are identified in patients with cancer of the cervix uteri, who receive various treatment modalities.

Pharmaceutical advertisements in medical journals received in a medical clinic: are we having "too much of a good thing"?

2005-01-01

A convenience sample of all medical journals found in a medical clinic was reviewed for pharmaceutical advertisements. Ads were present in 25 (96%) of the 26 journals. Ad space varied from 0-34% (mean 12) in research, and 9-48% (mean: 36) in nonresearch journals. In 23 (88%) journals, individual ads consisted of more than one page. Colorful glossy insert-ads, of up to nine pages, were seen in 18 (69%) journals. Six (23%) journals contained more advertising than editorial pages. Many ads were longer than the longest article in that journal. Medical journals devote considerable space to pharmaceutical ads. Excessive pharmaceutical advertising may bias the journals' owners and readers and may be distracting and annoying. PMID:15926650

[The influence of the devotion movement on the health care in North Korea].

PubMed

Choi, Young-In; Kim, Soo-Youn; Hwang, Sang-Ik

2006-06-01

Since the early 1960s, North Korea has conducted 'devotion movement' under the directorship of Kim Il Sung across the nation. As a matter of fact, the movement was not a novel invention at all. When North Korean Temporary People's Polity was established in 1946, North Korea emphasized the importance of the devoted care of health personnel. It meant to reform the people's thought and mind along with complementing the lack of human and material resources. Thought reform was not a peculiar phenomenon observed in North Korea only. It was particularly stressed out among communist countries, including the Soviet Union. However any other communist country stresses the importance of thought reform. Devotion movement should be viewed as part of this process. As shown in many cases, the extent and degree of devotion movement and care are beyond our imagination, which does not intend to mean that North Korean health personnel's attitude towards patients is superior to the counterparts in South Korea. Indeed human being's behavior cannot be understood without taking account of society in general. The question can be raised as to whether or not North Korean health personnel's devoted care is really voluntary. To put aside the testimony that the most powerless group in a society can fall prey to victims, if social environment, whether directly or indirectly, is action on the people's thought and mind even in a subtle way and thus influence one's decision power, it is hard to highly evaluate the devoted care in North Korea. Moreover it seems like that the internal conflict exists surrounding devotion. In conclusion, I think that North Korean devotion movement has enforced health personnel to reform their thought and mind to adapt to North Korean regime and has played an important role to accomplish the purpose of North Korean Labor Party to realize essential constituents of its health system, in such a situation in which essential medical supplies are severely lacking. But it seems like that it plays reverse action to develope sound North Korean health system.

Study of coherent synchrotron radiation effects by means of a new simulation code based on the non-linear extension of the operator splitting method

NASA Astrophysics Data System (ADS)

Dattoli, G.; Migliorati, M.; Schiavi, A.

2007-05-01

The coherent synchrotron radiation (CSR) is one of the main problems limiting the performance of high-intensity electron accelerators. The complexity of the physical mechanisms underlying the onset of instabilities due to CSR demands for accurate descriptions, capable of including the large number of features of an actual accelerating device. A code devoted to the analysis of these types of problems should be fast and reliable, conditions that are usually hardly achieved at the same time. In the past, codes based on Lie algebraic techniques have been very efficient to treat transport problems in accelerators. The extension of these methods to the non-linear case is ideally suited to treat CSR instability problems. We report on the development of a numerical code, based on the solution of the Vlasov equation, with the inclusion of non-linear contribution due to wake field effects. The proposed solution method exploits an algebraic technique that uses the exponential operators. We show that the integration procedure is capable of reproducing the onset of instability and the effects associated with bunching mechanisms leading to the growth of the instability itself. In addition, considerations on the threshold of the instability are also developed.

The recent discovery of an intermetallic superconductor MgB2 has renewed interest in the area of superconductivity not only because of fundamental understanding of superconductivity but also due to its potential applicability in devices such as thermal detectors. Considerable amount of research has been devoted to obtain MgB2 films by an all in situ growth technique. We have grown MgB2 thin films by an all in situ pulsed laser deposition process from pure B and Mg targets. Ultrathin layers of B and Mg were deposited in a multilayer configuration. Hundreds of such Mg-B bilayers with a capping Mg layer on the top were deposited on sapphire substrate. These depositions were done in high vacuum (approx. 10(exp -7) Torr) and at room temperature. After deposition, such a configuration was annealed at high temperature for a short time in a forming gas (4% H2 in Ar). The best films, obtained by this procedure, showed superconducting transition temperature approx. 30 K. These films have been characterized by x-ray diffraction, Rutherford Backscattering Spectrometry, AC susceptibility-, resistivity- (with and without magnetic field) and 1/f noise-measurements. The physical properties of these films will be presented and discussed.

Structural knowledge learning from maps for supervised land cover/use classification: Application to the monitoring of land cover/use maps in French Guiana

NASA Astrophysics Data System (ADS)

Bayoudh, Meriam; Roux, Emmanuel; Richard, Gilles; Nock, Richard

2015-03-01

The number of satellites and sensors devoted to Earth observation has become increasingly elevated, delivering extensive data, especially images. At the same time, the access to such data and the tools needed to process them has considerably improved. In the presence of such data flow, we need automatic image interpretation methods, especially when it comes to the monitoring and prediction of environmental and societal changes in highly dynamic socio-environmental contexts. This could be accomplished via artificial intelligence. The concept described here relies on the induction of classification rules that explicitly take into account structural knowledge, using Aleph, an Inductive Logic Programming (ILP) system, combined with a multi-class classification procedure. This methodology was used to monitor changes in land cover/use of the French Guiana coastline. One hundred and fifty-eight classification rules were induced from 3 diachronic land cover/use maps including 38 classes. These rules were expressed in first order logic language, which makes them easily understandable by non-experts. A 10-fold cross-validation gave significant average values of 84.62%, 99.57% and 77.22% for classification accuracy, specificity and sensitivity, respectively. Our methodology could be beneficial to automatically classify new objects and to facilitate object-based classification procedures.

The pedagogical implications of Maxwellian electromagnetic models: a case study from Victorian-Era physics.

PubMed

Bullock, Shawn Michael

2014-01-01

In the late Victorian Era, a group of British physicists devoted their time to interpreting and extending the work of James Clerk Maxwell. There has been considerable discussion about the ways in which these "Maxwellian" physicists used mechanical models by in the for research purposes; less attention has been paid to the relevance of their mechanical models for pedagogical purposes. Drawing from educational research literature, I begin from the premise that understanding a scientist's self-identity in its historical context is crucial to understanding how she or he enacts particular pedagogical approaches. I aim to extend Bruce Hunt's seminal work on the Maxwellians by providing a pedagogical analysis of one of Sir Oliver Lodge's lectures. In so doing, I claim that Lodge drew on his identity as a Maxwellian as an organizing framework for his lecture and that he attempted to engage his audience in Maxwellian thought by exposing them to many mechanical models. I conclude that Lodge's self-concept as a teacher and his apparent broad appeal as a public educationist were deeply embedded in his life history as a member of the Maxwellians. Sir Oliver Lodge's identities as a Maxwellian and a pedagogue are inextricably linked. Copyright © 2014 Elsevier Ltd. All rights reserved.

Stoves or Sugar? Willingness to Adopt Improved Cookstoves in Malawi

PubMed Central

Jagger, Pamela; Jumbe, Charles

2016-01-01

Malawi has set a target of adoption of two million improved cookstoves (ICS) by 2020. Meeting this objective requires knowledge about determinants of adoption, particularly in rural areas where the cost of traditional cooking technologies and fuels are non-monetary, and where people have limited capacity to purchase an ICS. We conducted a discrete choice experiment with 383 households in rural Malawi asking them if they would chose a locally made ICS or a package of sugar and salt of roughly equal value. Six months later, we assessed adoption and stove use patterns. Sixty-six percent of households chose the ICS. We find that having a larger share of crop residues in household fuel supply, awareness of the environmental impacts of woodfuel reliance, time the primary cook devotes to collecting fuelwood, and peer effects at the village-level increase the odds of choosing the ICS. Having a large labor supply for fuelwood collection and experience with a non-traditional cooking technology decreased the odds of choosing the ICS. In a rapid assessment six months after stoves were distributed, we found 80% of households were still using the ICS, but not exclusively. Our findings suggest considerable potential for wide-scale adoption of ICS in Malawi. PMID:27346912

Higgins, Stephen T

2016-11-01

This Special Issue of Preventive Medicine (PM) is the 3rd that we have organized on behavior change, health, and health disparities. This is a topic of critical importance to improving U.S. population health. There is broad scientific consensus that personal behaviors such as cigarette smoking, other substance abuse, and physical inactivity/obesity are among the most important modifiable causes of chronic disease and its adverse impacts on population health. Hence, effectively promoting health-related behavior change needs to be a key component of health care research and policy. There is also broad recognition that while these problems extend throughout the population, they disproportionately impact economically disadvantaged populations and other vulnerable populations and represent a major contributor to health disparities. Thus, behavior change represents an essential step in curtailing health disparities, which receives special attention in this 3rd Special Issue. We also devote considerable space to the longstanding challenges of reducing cigarette smoking and use of other tobacco and nicotine delivery products in vulnerable populations, obesity, and for the first time food insecurity. Across each of these topics we include contributions from highly accomplished policymakers and scientists to acquaint readers with recent accomplishments as well as remaining knowledge gaps and challenges.

Bilateral Orchidopexy in a Hypochondriacal (Somatic Symptom Disorder) Patient and Determination of Fitness for Bilateral Orchidectomy

PubMed Central

Allagoa, Erefagha Leonardo P.

2016-01-01

Introduction. DSM-5 identifies two disorders: somatic symptom disorder and illness anxiety disorder, to replace hypochondriasis in DSM-IV. Patients with both disorders are intensely anxious about the possibility of an undiagnosed illness or devote excessive time and energy to health concerns and are not easily reassured. Both disorders cause considerable distress and life disruption, even at moderate levels. However, hypochondriasis (DSM-IV) is an indication for neither orchidopexy nor orchidectomy. This is the rationale for this report which is the first of its kind to the best of available literature. This is an original case report of interest to a particular clinical specialty of mental health but it will have a broader clinical impact across medicine. Case Presentation. A 30-year-old black male presented to a primary care clinic with multiple internet searches on the topic of testicular pain and its differential diagnosis. He had a bilateral orchidopexy for a suspected torsion. He was referred to mental health unit, to determine fitness for further surgery. Conclusions. If hypochondriasis is suspected in a medical or surgical inpatient, a psychological medicine consultation should be performed, to elucidate the diagnosis, to avoid unnecessary procedures, and to optimize patient's care.

Dental School Administrators' Attitudes Towards Providing Support Services for LGBT-Identified Students.

Behar-Horenstein, Linda S; Morris, Dustin R

2015-08-01

A lack of curriculum time devoted to teaching dental students about the needs of lesbian, gay, bisexual, and transgendered (LGBT) health care patient needs and biases against LGBT students and faculty have been reported. Understanding dental school administrators' attitudes about LGBT students' needs might provide further insight into these long-standing issues. The aims of this study were to develop a survey to assess dental administrators' attitudes regarding the support services they believe LGBT-identified students need, to identify dental schools' current diversity inclusion policies, and to determine what types of support dental schools currently provide to LGBT students. A survey developed with the aid of a focus group, cognitive interviewing, and pilot testing was sent to 136 assistant and associate deans and deans of the 65 U.S. and Canadian dental schools. A total of 54 responses from 43 (66%) schools were received from 13 deans, 29 associate deans, and 11 assistant deans (one participant did not report a position), for a 40% response rate. The findings suggest there is a considerable lack of knowledge or acknowledgment of LGBT dental students' needs. Future studies are needed to show the importance of creating awareness about meeting the needs of all dental student groups, perhaps through awareness campaigns initiated by LGBT students.

The ice-related research of Harry Kiefte and co-workers

Clouter, M. J.

2003-01-01

Harry Kiefte (1942-1997) was born in Amsterdam and moved to Toronto at an early age where he completed his formal education. His Ph.D. research was in the field of electron paramagnetic resonance under J.S.M. Harvey at the University of Toronto. He then completed two years of postdoctoral study with B.P. Stoicheff at the same institution where he participated in the pioneering work that led to the recording of the first Brillouin spectra from single crystals of rare-gas solids and the consequent determination of the elastic constants for these materials. It was the technique of Brillouin spectroscopy, and its application to the determination of the elastic properties of a wide range of crystalline materials, that engaged his interest and very considerable talents for the remainder of his career at the Department of Physics, Memorial University, where he accepted a faculty position in 1973. At the time of his death, at the relatively young age of 54, his name appeared as author or co-author on approximately 90 publications. Included among the co-authors were four graduate students whose research was devoted to ice-related studies. It is this significant contribution to our knowledge of the elastic properties of ice that will be reviewed in this paper.

Analysis of ionization wave dynamics in low-temperature plasma jets from fluid modeling supported by experimental investigations

NASA Astrophysics Data System (ADS)

Yousfi, M.; Eichwald, O.; Merbahi, N.; Jomaa, N.

2012-08-01

This work is devoted to fluid modeling based on experimental investigations of a classical setup of a low-temperature plasma jet. The latter is generated at atmospheric pressure using a quartz tube of small diameter crossed by helium gas flow and surrounded by an electrode system powered by a mono-polar high-voltage pulse. The streamer-like behavior of the fast plasma bullets or ionization waves launched in ambient air for every high-voltage pulse, already emphasized in the literature from experimental or analytical considerations or recent preliminary fluid models, is confirmed by a numerical one-moment fluid model for the simulation of the ionization wave dynamics. The dominant interactions between electron and the main ions present in He-air mixtures with their associated basic data are taken into account. The gradual dilution of helium in air outside the tube along the axis is also considered using a gas hydrodynamics model based on the Navier-Stokes equation assuming a laminar flow. Due to the low magnitude of the reduced electric field E/N (not exceeding 15 Td), it is first shown that consideration of the stepwise ionization of helium metastables is required to reach the critical size of the electron avalanches in order to initiate the formation of ionization waves. It is also shown that a gas pre-ionization ahead of the wave front of about 109 cm-3 (coming from Penning ionization without considering the gas photo-ionization) is required for the propagation. Furthermore, the second ionization wave experimentally observed during the falling time of the voltage pulse, between the powered electrode and the tube exit, is correlated with the electric field increase inside the ionized channel in the whole region between the electrode and the tube exit. The propagation velocity and the distance traveled by the front of the ionization wave outside the tube in the downstream side are consistent with the present experimental measurements. In comparison with the streamer dynamics in a classical corona discharge, it is shown that under the same gas composition the plasma jet ionization waves propagate with a lower velocity (about 5 times), and have a higher diameter (at least 10 times) and a lower plasma density (at least 100 times).

Associations between Screen Time and Physical Activity among Spanish Adolescents

2011-01-01

Background Excessive time in front of a single or several screens could explain a displacement of physical activity. The present study aimed at determining whether screen-time is associated with a reduced level of moderate to vigorous physical activity (MVPA) in Spanish adolescents living in favorable environmental conditions. Methodology/Principal Findings A multi-stage stratified random sampling method was used to select 3503 adolescents (12–18 years old) from the school population of Gran Canaria, Spain. MVPA, screen-time in front of television, computer, video game console and portable console was assessed in the classroom by fulfilling a standardized questionnaire. Bivariate and multivariate logistic regression analyses adjusted by a set of social-environmental variables were carried out. Forty-six percent of girls (95% CI±2.3%) and 26% of boys (95% CI±2.1%) did not meet the MVPA recommendations for adolescents. Major gender differences were observed in the time devoted to vigorous PA, video games and the total time spent on screen-based activities. Boys who reported 4 hours•week−1 or more to total screen-time showed a 64% (OR = 0.61, 95% CI, 0.44–0.86) increased risk of failing to achieve the recommended adolescent MVPA level. Participation in organized physical activities and sports competitions were more strongly associated with MVPA than screen-related behaviors. Conclusions/Significance No single screen-related behavior explained the reduction of MVPA in adolescents. However, the total time accumulated through several screen-related behaviors was negatively associated with MVPA level in boys. This association could be due to lower availability of time for exercise as the time devoted to sedentary screen-time activities increases. Participation in organized physical activities seems to counteract the negative impact of excessive time in front of screens on physical activity. PMID:21909435

Excessive time in front of a single or several screens could explain a displacement of physical activity. The present study aimed at determining whether screen-time is associated with a reduced level of moderate to vigorous physical activity (MVPA) in Spanish adolescents living in favorable environmental conditions. A multi-stage stratified random sampling method was used to select 3503 adolescents (12-18 years old) from the school population of Gran Canaria, Spain. MVPA, screen-time in front of television, computer, video game console and portable console was assessed in the classroom by fulfilling a standardized questionnaire. Bivariate and multivariate logistic regression analyses adjusted by a set of social-environmental variables were carried out. Forty-six percent of girls (95% CI±2.3%) and 26% of boys (95% CI±2.1%) did not meet the MVPA recommendations for adolescents. Major gender differences were observed in the time devoted to vigorous PA, video games and the total time spent on screen-based activities. Boys who reported 4 hours•week(-1) or more to total screen-time showed a 64% (OR = 0.61, 95% CI, 0.44-0.86) increased risk of failing to achieve the recommended adolescent MVPA level. Participation in organized physical activities and sports competitions were more strongly associated with MVPA than screen-related behaviors. No single screen-related behavior explained the reduction of MVPA in adolescents. However, the total time accumulated through several screen-related behaviors was negatively associated with MVPA level in boys. This association could be due to lower availability of time for exercise as the time devoted to sedentary screen-time activities increases. Participation in organized physical activities seems to counteract the negative impact of excessive time in front of screens on physical activity.

With increased attention to patient privacy and autonomy, privacy protection and information provision for patients are becoming increasingly important. The aim of this study was to identify and analyse nurses' and patients' perceptions of the importance and performance of protecting patients' privacy and providing them with relevant information. This study is a descriptive cross-sectional investigation. Participants and research context: Participants were 168 patients hospitalised in medical and surgical wards and 176 nurses who cared for them. Ethical consideration: This study was approved by the Chung-Ang University Bioethics Committee, and informed written consent was collected from all participants. Nurses' recognition of the importance of protecting patients' privacy and providing adequate information was higher compared to their actual performance, and the nurses' level of performance was higher in comparison with the patients' recognition of its importance. Although a holistic approach to patient privacy protection and information provision is needed, the medical field has not embraced this model of care. These findings provide empirical data to create an ethical environment for the future, as considerable attention has been devoted to patients' rights and medical institutions' liability for providing explanations to patients.

Body mass index and economic productivity.

PubMed

Kennedy, E; Garcia, M

1994-11-01

The paper reviews the evidence to date on the nutritional links with productivity and then goes on to provide results from a multi-country study on the effects of increasing body mass index (BMI) on productivity. The research relating nutritional status to work capacity is more consistent than the research linking nutritional status to productivity. None of the studies to date elucidate the pathways through which improved nutrition improves economic productivity. In addition, many of the studies that have been conducted on the nutrition/wage links have been based on samples that contained a disproportionate number of male subjects. The few studies that have disaggregated data by gender report different results for men and women. Research conducted at IFPRI is presented to examine the trends in BMI for men and women across countries and for Kenya to examine the relationships between various measures of nutritional status--BMI and height--and energy expenditures in women. BMIs of men show a more consistent relationship with increasing household income than do the BMIs of women. In the case of the Gambia and Kenya, the mean BMI of women decreases with increasing household income. One reason for the apparently low response of BMI to increasing household income in Kenya is the time allocation patterns of women. Women in the Kenya sample spend the largest proportion of their day in home production activities which are energy intensive. In examining the relationship between nutritional indicators and the time devoted to work, the results suggest a significant, positive association between both BMI and height and the amount of time devoted to work. In the models presented, both BMI and height appear to increase the capacity to carry out work. It is difficult to value much of this work time since a disproportionate share is devoted to home production activities. Some of the more classic methods of measuring economic productivity, such as measuring wage rates, are not relevant for women in this setting. The data from Kenya suggest that more appropriate measures for specifying the value of women's work need to be developed in order to capture some of the nutrition/productivity links which may exist.

Toward a community ecology of landscapes: predicting multiple predator-prey interactions across geographic space.

Schmitz, Oswald J; Miller, Jennifer R B; Trainor, Anne M; Abrahms, Briana

2017-09-01

Community ecology was traditionally an integrative science devoted to studying interactions between species and their abiotic environments in order to predict species' geographic distributions and abundances. Yet for philosophical and methodological reasons, it has become divided into two enterprises: one devoted to local experimentation on species interactions to predict community dynamics; the other devoted to statistical analyses of abiotic and biotic information to describe geographic distribution. Our goal here is to instigate thinking about ways to reconnect the two enterprises and thereby return to a tradition to do integrative science. We focus specifically on the community ecology of predators and prey, which is ripe for integration. This is because there is active, simultaneous interest in experimentally resolving the nature and strength of predator-prey interactions as well as explaining patterns across landscapes and seascapes. We begin by describing a conceptual theory rooted in classical analyses of non-spatial food web modules used to predict species interactions. We show how such modules can be extended to consideration of spatial context using the concept of habitat domain. Habitat domain describes the spatial extent of habitat space that predators and prey use while foraging, which differs from home range, the spatial extent used by an animal to meet all of its daily needs. This conceptual theory can be used to predict how different spatial relations of predators and prey could lead to different emergent multiple predator-prey interactions such as whether predator consumptive or non-consumptive effects should dominate, and whether intraguild predation, predator interference or predator complementarity are expected. We then review the literature on studies of large predator-prey interactions that make conclusions about the nature of multiple predator-prey interactions. This analysis reveals that while many studies provide sufficient information about predator or prey spatial locations, and thus meet necessary conditions of the habitat domain conceptual theory for drawing conclusions about the nature of the predator-prey interactions, several studies do not. We therefore elaborate how modern technology and statistical approaches for animal movement analysis could be used to test the conceptual theory, using experimental or quasi-experimental analyses at landscape scales. © 2017 by the Ecological Society of America.

Noise in neonatal intensive care units (NICUs) and its effect on high risk newborns

We conducted sound surveys in a large state of the art NICU with six separate rooms devoted to the sickest babies requiring the most intensive care (Level III) and six rooms devoted to babies requiring special but less intensive care (Level II). Each room was capable of caring for up to 8 babies. Additionally, there were 8 individual Isolation rooms. We used Larson Davis Spark squflg 703+ dosimeters to record 21 week long sound surveys, seven in each type of room. The American Academy of Pediatrics (1997) has recommended that sound levels in NICUs should never exceed 45 dB(A). That recommendation was exceeded 73.6% of the time in Level II, 92.1% of the time in Isolation, and 96.6% of the time in Level III. Sound levels were lowest in the Level II rooms especially for the softest sounds recorded (L90 and L70). Level III rooms were noisiest except for the noisiest decile of sound (L10). Isolation rooms were noisiest at the highest sound levels (probably because of their reverberant construction materials and enclosed space). Autocorrelation functions were calculated identifying periodic components in all three rooms at about 12 and 24 hrs. Periodic variations were very small compared to random sound variations.

Cooperative learning as applied to resident instruction in radiology reporting.

Mueller, Donald; Georges, Alexandra; Vaslow, Dale

The study is designed to evaluate the effectiveness of an active form of resident instruction, cooperative learning, and the residents' response to that form of instruction. The residents dictated three sets of reports both before and after instruction in radiology reporting using the cooperative learning method. The reports were evaluated for word count, Flesch-Kincaid grade level, advancement on clinical spectrum, clarity, and comparison to prior reports. The reports were evaluated for changes in performance characteristics between the pre- and postinstruction dictations. The residents' response to this form of instruction was evaluated by means of a questionnaire. The instruction was effective in changing the resident dictations. The results became shorter (P<.035), more complex (P<.0126), and demonstrated increased advancement on clinical spectrum (P<.0204). The resident response to this form of instruction was positive. One hundred percent or respondents indicated enjoyment working with their groups. Seventy-five percent stated they would like to participate in more cooperative learning activities. The least positive responses related to the amount of time devoted to the project. Sixty-three percent of respondents stated that the time devoted to the project was appropriate. Cooperative learning can be an effective tool in the setting of the radiology residency. Instructional time requirements must be strongly considered in designing a cooperative learning program.
