Focusing and depth of field in photography: application in dermatology practice.

PubMed

Taheri, Arash; Yentzer, Brad A; Feldman, Steven R

2013-11-01

Conventional photography obtains a sharp image of objects within a given 'depth of field'; objects not within the depth of field are out of focus. In recent years, digital photography revolutionized the way pictures are taken, edited, and stored. However, digital photography does not result in a deeper depth of field or better focusing. In this article, we briefly review the concept of depth of field and focus in photography as well as new technologies in this area. A deep depth of field is used to have more objects in focus; a shallow depth of field can emphasize a subject by blurring the foreground and background objects. The depth of field can be manipulated by adjusting the aperture size of the camera, with smaller apertures increasing the depth of field at the cost of lower levels of light capture. Light-field cameras are a new generation of digital cameras that offer several new features, including the ability to change the focus on any object in the image after taking the photograph. Understanding depth of field and camera technology helps dermatologists to capture their subjects in focus more efficiently. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Psychodynamic Therapists' Reservations About Cognitive-Behavioral Therapy

PubMed Central

PERSONS, JACQUELINE B.; GROSS, JAMES J.; ETKIN, MARK S.; MADAN, SIMONE K.

1996-01-01

This article offers suggestions for psychodynamic therapists who encounter obstacles while learning cognitive-behavioral therapy (CBT) or working in settings where CBT is used. The authors discuss three types of questions commonly raised by psychodynamic therapists about CBT. These concern 1) the therapeutic relationship, 2) the focus of therapeutic interventions, and 3) the depth of change. To help psychodynamic therapists overcome obstacles to learning CBT, the authors focus on similarities between psychodynamic and cognitive-behavioral models in these three areas. They also examine differences between the models, including differences dependent on value judgments, and offer suggestions for making productive use of differences between the models in the training process.

Adlmann, Franz A.; Herbel, Jörg; Korolkovas, Airidas; Bliersbach, Andreas; Toperverg, Boris; Van Herck, Walter; Pálsson, Gunnar K.; Kitchen, Brian; Wolff, Max

Grazing incidence neutron scattering experiments offer surface sensitivity by reflecting from an interface at momentum transfers close to total external reflection. Under these conditions the penetration depth is strongly non-linear and may change by many orders of magnitude. This fact imposes severe challenges for depth resolved experiments, since the brilliance of neutron beams is relatively low in comparison to e.g. synchrotron radiation. In this article we use probability density functions to calculate the contribution of scattering at different distances from an interface to the intensities registered on the detector. Our method has the particular advantage that the depth sensitivity is directly extracted from the scattering pattern itself. Hence for perfectly known samples exact resolution functions can be calculated and visa versa. We show that any tails in the resolution function, e.g. Gaussian shaped, hinders depth resolved experiments. More importantly we provide means for a descriptive statistical analysis of detector images with respect to the scattering contributions and show that even for perfect resolution near surface scattering is hardly accessible.

2016-01-01

The purpose of this article is to present images from simulated breast microcalcifications and assess the pattern of the microcalcifications with a technical development called "depth 3-dimensional (D3D) augmented reality". A computer, head display unit, joystick, D3D augmented reality software, and an in-house script of simulated data of breast microcalcifications in a ductal distribution were used. No patient data was used and no statistical analysis was performed. The D3D augmented reality system demonstrated stereoscopic depth perception by presenting a unique image to each eye, focal point convergence, head position tracking, 3D cursor, and joystick fly-through. The D3D augmented reality imaging system offers image viewing with depth perception and focal point convergence. The D3D augmented reality system should be tested to determine its utility in clinical practice.

The use of bisphosphonates does not contraindicate orthodontic and other types of treatment!

PubMed Central

Consolaro, Alberto

2014-01-01

Bisphosphonates have been increasingly used not only to treat bone diseases as well as conditions such as osteopenia and osteoporosis, but also in oncotherapy. The use of bisphosphonates induces clinicians to fear and care. These reactions are associated with controversy resulting from lack of in-depth knowledge on the mechanisms of action as well as lack of a more accurate assessment of side effects. Scientific and clinical knowledge disclosure greatly contributes to professionals' discernment and inner balance, especially orthodontists. Fear does not lead to awareness. For these reasons, we present an article that focuses on that matter. This article was adapted from different journals of different dental specialties, as mentioned on footnote. There is no scientific evidence demonstrating that bisphosphonates are directly involved with etiopathogenic mechanisms of osteonecrosis and jaw osteomyelitis. Their use is contraindicated and limited in cases of dental treatment involving bone tissue. Nevertheless, such fact is based on professional opinion, case reports, and personal experience or experiment trials with failing methods. Additional studies will always be necessary; however, in-depth knowledge on bone biology is of paramount importance to offer an opinion about the clinical use of bisphosphonates and their further implications. Based on bone biopathology, this article aims at contributing to lay the groundwork for this matter. PMID:25279517

Women with HIV who want to have children face a range of challenges, quandaries, and hard decisions. This article examines the role of health staff in supporting HIV-infected pregnant women who desire to maintain their pregnancies. The article is derived from anthropological research conducted in Vietnam's Quang Ninh Province, an area that has a high HIV prevalence rate and is covered under the government's prevention of mother-to-child transmission program. The study included in-depth interviews with 23 HIV-infected women who had either recently given birth or were pregnant at the time of the research. Results showed that women were satisfied with the services they received from the program. The women believed that health care staff offered them not only medical care but also social and emotional support. The article concludes that the health care system is a vital point of support for pregnant women with HIV.

2008-01-01

By now there is a relatively broadly based basic research as to burden and developmental risks in children of mentally ill parents. Nevertheless, hardly any studies exist focusing the living situation of teenagers concerned. This article presents results from an in-depth interview study with 15 adolescents (15 to 21 years old) who have a mentally ill parent. Particularly, the living situation of the study participants was explored from the perspective of developmental psychology, i. e. considering age-specific developmental tasks. The results show that, in many cases, daily life and future perspectives of adolescents are greatly affected by the mental illness of a parent. Based on the results of the study, the article presents conclusions for further research and psychosocial practice. Generally, professional assistance for children of mentally ill people should be on hand as early as possible. When planning specific help offers for adolescents affected, compatibility to their emotional life-world should be taken into consideration. Involving peer counsellors and offering web-based psychological assistance can contribute to better get in touch with adolescent clients.

Changing behavior towards sustainable practices using Information Technology.

PubMed

Iveroth, Einar; Bengtsson, Fredrik

2014-06-15

This article addresses the question of how to change individuals' behavior towards more sustainable practices using Information Technology (IT). By following a multidisciplinary and socio-technical perspective, this inquiry is answered by applying a new framework-The Commonality Framework for IT-enabled Change-on a case study of sustainable behavioral change. The framework is grounded in practice theory and is used to analyze the implementation of an IT-system aimed at changing citizens' behavior towards more sustainable transport logistics and procurement in Uppsala, Sweden. The article applies case study research design and the empirical data consists of surveys, in-depth and semi-structured interviews, observations and archival documents. The results show how the change towards sustainable practices is an entanglement of both social and technical-structural elements across time. In this process, structures such as IT are the enablers, and the actors and their social activities are the tipping-point factors that ultimately determine the success of changing individuals' behavior towards a more sustainable direction. This article provides a more balanced view of how both actor and structure related properties interact during the on-going work with change towards greater sustainability practices than earlier research has offered. More specifically, the article offers both a lower-level theory and a method from which we can analyze change processes where technology is seen in its context, and where both technology and the human actor is brought forth to center stage.

Optical Imaging of Ionizing Radiation from Clinical Sources

PubMed Central

Shaffer, Travis M.; Drain, Charles Michael

2016-01-01

Nuclear medicine uses ionizing radiation for both in vivo diagnosis and therapy. Ionizing radiation comes from a variety of sources, including x-rays, beam therapy, brachytherapy, and various injected radionuclides. Although PET and SPECT remain clinical mainstays, optical readouts of ionizing radiation offer numerous benefits and complement these standard techniques. Furthermore, for ionizing radiation sources that cannot be imaged using these standard techniques, optical imaging offers a unique imaging alternative. This article reviews optical imaging of both radionuclide- and beam-based ionizing radiation from high-energy photons and charged particles through mechanisms including radioluminescence, Cerenkov luminescence, and scintillation. Therapeutically, these visible photons have been combined with photodynamic therapeutic agents preclinically for increasing therapeutic response at depths difficult to reach with external light sources. Last, new microscopy methods that allow single-cell optical imaging of radionuclides are reviewed. PMID:27688469

One of the tasks of developing and implementing defectoscopy devices is the minimal influence of the human factor in their exploitation. At present, rail inspection systems do not have sufficient depth of rail research, and ultrasonic diagnostics systems need to contact the sensor with the surface being studied, which leads to low productivity. The article gives a comparative analysis of existing noncontact methods of flaw detection, offers a contactless method of diagnostics by excitation of acoustic waves and extraction of information about defects from the frequency of free rail oscillations using the radar method.

Depoliticisation, Resilience and the Herceptin Post-Code Lottery Crisis: Holding Back the Tide

PubMed Central

2015-01-01

Research Highlights and Abstract This article: Covers new empirical terrain in the study of depoliticisation, with an in-depth case study of health technology regulation; Analyses depoliticisation from a novel analytical perspective, examining how depoliticised institutions are resilient to external pressure for politicisation; Posits a distinctive framework for analysing resilience, drawing on cognate literatures on policy networks and agencification; Raises interesting and distinctive questions about the nature of depoliticisation in advanced liberal democracies, arguing it is more contested than commonly acknowledged. Depoliticisation as a concept offers distinctive insights into how governments attempt to relieve political pressures in liberal democracies. Analysis has examined the effects of depoliticisation tactics on the public, but not how those tactics are sustained during moments of political tension. Drawing on policy networks and agencification literatures, this article examines how these tactics are resilient against pressure for politicisation. Using an in-depth case study of the controversial appraisal of cancer drug Herceptin in 2005/6 by the National Institute for Health and Clinical Excellence (NICE), the article examines how ‘resilient’ NICE was to external politicisation. It is argued that NICE was resilient because it was effectively ‘insulated’ by formal procedures and informal norms of deference to scientific expertise. This mechanism is termed ‘institutional double glazing’. The conclusion suggests developments to the conceptual and methodological framework of depoliticisation, and highlights theoretical insights into the nature of ‘anti-politics’ in contemporary democracies.

Informal, coercive residential centers for the treatment of addiction are widespread and growing throughout Latin America. In Mexico these centers are called "anexos" and they are run and utilized by low-income individuals and families with problems related to drugs and alcohol. This article draws on findings from a 3-year anthropological study of anexos in Mexico City. Participant observation and in-depth interviews were used to describe and analyze anexos, their therapeutic practices, and residents' own accounts of addiction and recovery. Our findings indicate that poverty, addiction, and drug-related violence have fueled the proliferation of anexos They also suggest that anexos offer valuable health, social, and practical support, but risk exacerbating the suffering of residents through coercive rehabilitation techniques. Emphasizing this tension, this article considers the complex relationship between coercion and care, and poses fundamental questions about what drug recovery consists of in settings of poverty and violence. © The Author(s) 2016.

Comparison of 2 recommendations for adjusting the working height in milking parlors.

PubMed

Jakob, Martina C; Liebers, Falk

2017-08-01

Milking cows is one of the major labor inputs on dairy farms. Modern parlors allow upright working positions, but pain and disorders among parlor workers are still very prevalent. The platform height in the parlors is important for the body posture of the workers. Based on a large set of data containing parlor-specific measures, anthropometrics, and bovimetrics, a simulation of 2 recommendations published in the literature was carried out. This article presents and discusses the results of 2 formulas for determining the appropriate pit depth. The shoulder and body height of the worker and the distance between the udder and the floor influence the adjustment of the pit depth. If work at shoulder level is favored, autotandem parlors offer the most suitable pit depths, whereas side-by-side parlors are too deep in all cases. Due to the variation in anthropometrics and bovimetrics, a good parlor design can reduce the extent of unfavorable body postures, but more technical measures are necessary to completely eliminate them. Actions that reduce the workload and the prevalence of musculoskeletal pain and disorders should be considered. Copyright © 2017 American Dairy Science Association. Published by Elsevier Inc.

2018-01-01

As ischemia remains a key prognostic factor in the management of various diseases including diabetic retinopathy, an increasing amount of research has been dedicated to its quantification as a potential biomarker. Advancements in the quantification of retinal ischemia have been made with the imaging modalities of fluorescein angiography (FA), ultra-widefield imaging (UWF), and optical coherence tomography angiography (OCTA), with each imaging modality offering certain benefits over the others. FA remains the gold standard in assessing the extent of ischemia. UWF imaging has allowed for the assessment of peripheral ischemia via FA. It is, however, OCTA that offers the best visualization of retinal vasculature with its noninvasive depth-resolved imaging and therefore has the potential to become a mainstay in the assessment of retinal ischemia. The primary purpose of this article is to review the use of FA, UWF, and OCTA to quantify retinal ischemia and the various methods described in the literature by which this is achieved.

Wilhelm, K-P; Wilhelm, D; Bielfeldt, S

2017-02-01

The healing of wounds has always provided challenges for the medical community whether chronic or acute. Understanding the processes which enable wounds to heal is primarily carried out by the use of models, in vitro, animal and human. It is generally accepted that the use of human models offers the best opportunity to understand the factors that influence wound healing as well as to evaluate efficacy of treatments applied to wounds. The objective of this article is to provide an overview of the different methodologies that are currently used to experimentally induce wounds of various depths in human volunteers and examines the information that may be gained from them. There is a number of human volunteer healing models available varying in their invasiveness to reflect the different possible depth levels of wounds. Currently available wound healing models include sequential tape stripping, suction blister, abrasion, laser, dermatome, and biopsy techniques. The various techniques can be utilized to induce wounds of variable depth, from removing solely the stratum corneum barrier, the epidermis to even split-thickness or full thickness wounds. Depending on the study objective, a number of models exist to study wound healing in humans. These models provide efficient and reliable results to evaluate treatment modalities. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Prostate and Colon Cancer Screening Messages in Popular Magazines

2004-01-01

OBJECTIVES To 1) compare the number of articles published about prostate, colon, and breast cancer in popular magazines during the past 2 decades, and 2) evaluate the content of in-depth prostate and colon cancer screening articles identified from 1996 to 2001. DESIGN We used a searchable database to identify the number of prostate, colon, and breast cancer articles published in three magazines with the highest circulation from six categories. In addition, we performed a systematic review on the in-depth (≥2 pages) articles on prostate and colon cancer screening that appeared from 1996 through 2001. RESULTS Although the number of magazine articles on prostate and colon cancer published in the 1990s increased compared to the 1980s, the number of articles is approximately one third of breast cancer articles. There were 36 in-depth articles from 1996 to 2001 in which prostate or colon cancer screening were mentioned. Over 90% of the articles recommended screening. However, of those articles, only 76% (25/33; 95% confidence interval [CI], 58% to 89%) cited screening guidelines. The benefits of screening were mentioned in 89% (32/36; 95% CI, 74% to 97%) but the harms were only found in 58% (21/36; 95% CI, 41% to 75%). Only 28% (10/36; 95% CI, 14% to 45%) of the articles provided all the necessary information needed for the reader to make an informed decision. CONCLUSIONS In-depth articles about prostate and colon cancer in popular magazines do not appear as frequently as articles about breast cancer. The available articles on prostate and colon cancer screening often do not provide the information necessary for the reader to make an informed decision about screening. PMID:15242469

The high precision and scalable technology offered by atom interferometry has the opportunity to profoundly affect gravity surveys, enabling the detection of features of either smaller size or greater depth. While such systems are already starting to enter into the commercial market, significant reductions are required in order to reach the size, weight and power of conventional devices. In this article, the potential for atom interferometry based gravimetry is assessed, suggesting that the key opportunity resides within the development of gravity gradiometry sensors to enable drastic improvements in measurement time. To push forward in realizing more compact systems, techniques have been pursued to realize a highly portable magneto-optical trap system, which represents the core package of an atom interferometry system. This can create clouds of 107 atoms within a system package of 20 l and 10 kg, consuming 80 W of power. This article is part of the themed issue 'Quantum technology for the 21st century'.

While such systems are already starting to enter into the commercial market, significant reductions are required in order to reach the size, weight and power of conventional devices. In this article, the potential for atom interferometry based gravimetry is assessed, suggesting that the key opportunity resides within the development of gravity gradiometry sensors to enable drastic improvements in measurement time. To push forward in realizing more compact systems, techniques have been pursued to realize a highly portable magneto-optical trap system, which represents the core package of an atom interferometry system. This can create clouds of 107 atoms within a system package of 20 l and 10 kg, consuming 80 W of power. This article is part of the themed issue ‘Quantum technology for the 21st century’.

Approaches to emergency management teaching at the master's level.

PubMed

Alexander, David

2013-01-01

Training and education enable emergency managers to deal with complex situations, create durable networks of people with appropriate expertise, and ensure that knowledge is utilized to improve resilience in the face of disaster risk. Although there is a discrete literature on emergency management training, few attempts have been made to create an overview that discusses the key issues and proposes a standardized approach. This article examines the nature of training and education in emergency and disaster management. It analyzes the composition and requirements of courses at the master's degree level, which is considered to be the most appropriate tier for in-depth instruction in this field. This article defines "training" and "education" in the context of emergency management courses. It reviews the developing profile of the emergency manager in the light of training requirements. This article examines the question of whether emergency management is a branch of management science or whether it is something distinct and separate. Attention is given to the composition of a core curriculum and to the most appropriate pedagogical forms of delivering it. The article reviews the arguments for and against standardization of the curriculum and describes some of the pedagogical methods for delivering courses. Briefly, it considers the impact on training and education of new pedagogic methods based on information technology. It is concluded that the master's level is particularly suited to emergency and crisis management education, as it enables students to complement the in-depth knowledge they acquired in their disciplinary first degrees with a broader synthetic approach at the postgraduate level. Some measures of standardization of course offerings are desirable, in favor of creating a core curriculum that will ensure that essential core knowledge is imparted. Education and training in this field should include problem-solving approaches that enable students to learn practical skills as well as theory.

In search of the cancer candidate: can lay epidemiology help?

PubMed

Macdonald, Sara; Watt, Graham; Macleod, Una

2013-05-01

First published in 1991, the ideas embedded in 'Lay epidemiology and the prevention paradox' offered a novel and rational explanation for the lay public's failure to fully engage with the lifestyle messages offered by health educators. During the course of a large ethnographic study in South Wales, Davison and colleagues described the emergence of what they termed the coronary candidate. Candidacy provides a 'cultural mechanism' that facilitates the estimation of risk for coronary heart disease. The model has rarely been applied to other major illnesses. This article presents findings from a study that sought to explore the lay epidemiology model, candidacy and cancer. In a series of in-depth individual interviews, members of the lay public discussed their ideas about cancer, and what emerged was an explanatory hierarchy to account for cancer events. Yet the random and unpredictable nature of cancer was emphasised as well as a general reluctance to accept the idea of cancer candidacy. © 2012 The Authors.

The qualitative interview and challenges for clinicians undertaking research: a personal reflection.

PubMed

Fisher, Karin

2011-01-01

Drawing on my doctoral experience the aim of this article is to present my transition from practitioner to novice researcher and the challenges I encountered when undertaking qualitative in-depth interviews. The contents of my research diary were coded for words, sentences and paragraphs and were then grouped into themes and subsequently organised into concepts and categories. The analysis identified one core category: 'changing states: learning to become a researcher'. The related categories included 'guessing responses', 'confusing boundaries' and 'revealing hidden concepts'. These concepts provide a description of how I learnt to become a researcher and became a changed state. The paper provides practitioners with practical examples of my transition from practitioner to novice researcher. I offer some tips for practitioners who wish to undertake research in their clinical role.

"Tangled wires in the head": older migrant Chinese's perception of mental illness in Britain.

PubMed

Li, Sarah; Hatzidimitriadou, Eleni; Psoinos, Maria

2014-08-01

In this article, the authors explored Cantonese-speaking older Chinese migrants knowledge, attitudes and expectations regarding mental illness. They obtained verbatim data from semi-structured interviews with eight participants recruited from London-based Chinese and church communities in Britain. They analyzed the data using the principles of Grounded Theory and in-depth content analysis. They examined cultural idioms in participants' accounts. Findings suggested that Western diagnostic categories of mental illness were alien to participants. They had a culturally constructed way of defining and characterizing mental illness. Participants used idioms of 'nerve', 'mood', 'behavior', 'personality', 'normal life', 'compassion' and the idiom of 'others' to construct an alternative world for stigma management. They erected an invisible but permeable barrier to limit access to their normal world. The role of traditional Chinese culture of Confucianism was significant in shaping perceptions and conceptions of mental illness. This article offered another perspective on the alternative world of Chinese migrants' cultural understandings of mental illness, an area with limited understanding at present. The authors discussed important implications for future research and social policy. Copyright © 2014 Elsevier Inc. All rights reserved.

Older Workers and Federal Work Programs: The Korean Senior Employment Program (KSEP).

PubMed

Choi, Eunhee

2016-01-01

Federal older worker programs are attracting attention due to the growing number of older workers across the world. They are uniquely situated to provide out-of-market work opportunities to older job seekers, who often find their age a barrier to securing desirable jobs. In 2004, the Korean government established its own program, the Korean Senior Employment Program (KSEP); however, literature for international readers on this innovative program is lacking. Thus, this article aims to provide an in-depth description of KSEP and a brief comparison between the Senior Community Service Employment Program in the U.S. and KSEP. The unique characteristics of KSEP include having the dual program foci on supplemental income and social participation; expanding work opportunities in the private sector beyond community-based jobs; accepting participants who are financially disadvantaged as well as those with a high desire for social participation regardless of their income; and broadening work opportunities for those with professional skills beyond repetitive, simple, and temporary jobs. This article may offer helpful insights to older worker advocates from various countries in creating or modifying their programs.

Meaning Reconstruction among Women following Stillbirth: A Loss Fraught with Ambiguity and Doubt.

PubMed

Golan, Aiya; Leichtentritt, Ronit Dina

2016-08-01

Stillbirth (SB), death of a fetus in late stages of pregnancy or during birth, usually leads to extended and intense grief among women. However, their grief is often disenfranchised and they are denied the social right to mourn their loss. Constructivist theories recently assuming a central place in bereavement studies inform this article, which aims to identify the meaning that women who experience SB ascribe to their loss in general and to the lost figure. This tack may offer the opportunity to examine the consequences of the discrepancy between personal and environmental constructions of this loss on its personal construction and to learn about the essence of the loss. Within the domain of qualitative research, the current article draws on phenomenology and the research method that has emerged from this approach. Specifically, the article focuses on in-depth interviews with 10 women who experienced SB. Its findings suggest that for these women, the lost figure and the loss in general engender ambiguity both internally-that is, within the psyche of women themselves-and externally, within the women's social environment. Thus, ambiguity, uncertainty, and doubt infused women's experience of SB. Implications for theory and practice are discussed. © 2016 National Association of Social Workers.

From Energy Audits to Home Performance: 30 Years of Articles in Home Energy Magazine

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

Meier, Alan

Home Energy Magazine has been publishing articles about residential energy efficiency for 30 years. Its goal has been to disseminate technically reliable and neutral information to the practitioners, that is, professionals in the business of home energy efficiency. The articles, editorials, letters, and advertisements are a kind of window on the evolution of energy conservation technologies, policies, and organizations. Initially, the focus was on audits and simple retrofits, such as weatherstripping and insulation. Instrumentation was sparse sometimes limited to a ruler to measure depth of attic insulation and a blower door was exotic. CFLs were heavy, awkward bulbs which might,more » or might not, fit in a fixture. Saving air conditioning energy was not a priority. Solar energy was only for the most adventurous. Thirty years on, the technologies and business have moved beyond just insulating attics to the larger challenge of delivering home performance and achieving zero net energy. This shift reflects the success in reducing space heating energy and the need to create a profitable industry by providing more services. The leading edge of the residential energy services market is becoming much more sophisticated, offering both efficiency and solar systems. The challenge is to continue providing relevant and reliable information in a transformed industry and a revolutionized media landscape.« less

The salience of family worldview in mourning an elderly husband and father.

PubMed

Black, Helen K; Santanello, Holly R

2012-08-01

The purpose of this study was to qualitatively explore family reaction to the death of the elderly husband and father in the family. We qualitatively interviewed 34 families (a family included a widow and 2 adult biological children) approximately 6-15 months after the death. In private, one-on-one in-depth interviews, we discussed how the death affected each family member as an individual and how each member perceived that the death altered the family as a unit. An individual's worldview, embedded in the smaller culture of the family and the larger culture of society, offers a template for appropriate grief reactions. Our article builds on the constructs of worldview, grief for the husband and father, and narrative at the juncture of self-evaluation, as family members reflected on where they stood in their own journey through life.

2013-12-01

To analyze how food values and other variables related to dietary acculturation affect international university students' food buying decisions, this article provides an in-depth review of relevant literature related to the food buying decisions of groups of sojourners, which suggest several research hypotheses. The data collection targeted international university students in Spain and used factorial analysis of the main components together with linear parametric regressions. The resulting findings offer distinct insights, according to sojourners' continent of origin. Specifically, whereas European students exhibit a higher propensity to value sustainable production practices in the food choices, American students emphasize flavor and exhibit a greater degree of adaptation. These findings in turn suggest some key managerial recommendations and research guidelines for both private and public operators in related fields. Copyright © 2013 Elsevier Ltd.

The Lublin voivodeship has the rich multiethnic and multi-denominational heritage. It can constitute an attractive tourist product of the region and a regional brand. However, the tourist potential of the region based on material and spiritual relics of the past is not wholly used off. This article presents a spatial position of the most important cultural heritage objects in the Lublin region, as well as suggestions to their effective use in various forms of tourism. The presented ideas relate to well-tested European and global solutions in the field of culture-based tourist offer. They can serve as an inspiration for local administration in the process of preparing the strategy of actions aimed at economical development of selected areas of the voivodeship. Due to the limited print space, the paper does not provide the in-depth analysis of the problem.

Solar Radiation on Mars: Tracking Photovoltaic Array

NASA Technical Reports Server (NTRS)

Appelbaum, Joseph; Flood, Dennis J.; Crutchik, Marcos

1994-01-01

A photovoltaic power source for surface-based operation on Mars can offer many advantages. Detailed information on solar radiation characteristics on Mars and the insolation on various types of collector surfaces are necessary for effective design of future planned photovoltaic systems. In this article we have presented analytical expressions for solar radiation calculation and solar radiation data for single axis (of various types) and two axis tracking surfaces and compared the insulation to horizontal and inclined surfaces. For clear skies (low atmospheric dust load) tracking surfaces resulted in higher insolation than stationary surfaces, whereas for highly dusty atmospheres, the difference is small. The insolation on the different types of stationary and tracking surfaces depend on latitude, season and optical depth of the atmosphere, and the duration of system operation. These insolations have to be compared for each mission.

Quality assurance in proton beam therapy using a plastic scintillator and a commercially available digital camera.

PubMed

Almurayshid, Mansour; Helo, Yusuf; Kacperek, Andrzej; Griffiths, Jennifer; Hebden, Jem; Gibson, Adam

2017-09-01

In this article, we evaluate a plastic scintillation detector system for quality assurance in proton therapy using a BC-408 plastic scintillator, a commercial camera, and a computer. The basic characteristics of the system were assessed in a series of proton irradiations. The reproducibility and response to changes of dose, dose-rate, and proton energy were determined. Photographs of the scintillation light distributions were acquired, and compared with Geant4 Monte Carlo simulations and with depth-dose curves measured with an ionization chamber. A quenching effect was observed at the Bragg peak of the 60 MeV proton beam where less light was produced than expected. We developed an approach using Birks equation to correct for this quenching. We simulated the linear energy transfer (LET) as a function of depth in Geant4 and found Birks constant by comparing the calculated LET and measured scintillation light distribution. We then used the derived value of Birks constant to correct the measured scintillation light distribution for quenching using Geant4. The corrected light output from the scintillator increased linearly with dose. The system is stable and offers short-term reproducibility to within 0.80%. No dose rate dependency was observed in this work. This approach offers an effective way to correct for quenching, and could provide a method for rapid, convenient, routine quality assurance for clinical proton beams. Furthermore, the system has the advantage of providing 2D visualization of individual radiation fields, with potential application for quality assurance of complex, time-varying fields. © 2017 The Authors.

Trade-offs in sensitivity and sampling depth in bimodal atomic force microscopy and comparison to the trimodal case

PubMed Central

Eslami, Babak; Ebeling, Daniel

2014-01-01

Summary This paper presents experiments on Nafion® proton exchange membranes and numerical simulations illustrating the trade-offs between the optimization of compositional contrast and the modulation of tip indentation depth in bimodal atomic force microscopy (AFM). We focus on the original bimodal AFM method, which uses amplitude modulation to acquire the topography through the first cantilever eigenmode, and drives a higher eigenmode in open-loop to perform compositional mapping. This method is attractive due to its relative simplicity, robustness and commercial availability. We show that this technique offers the capability to modulate tip indentation depth, in addition to providing sample topography and material property contrast, although there are important competing effects between the optimization of sensitivity and the control of indentation depth, both of which strongly influence the contrast quality. Furthermore, we demonstrate that the two eigenmodes can be highly coupled in practice, especially when highly repulsive imaging conditions are used. Finally, we also offer a comparison with a previously reported trimodal AFM method, where the above competing effects are minimized. PMID:25161847

Albrigtsen, Vårin; Eskeland, Benedicte; Mæhle, Magne

2016-04-01

This article is based on an in-depth interview with a pair of twins diagnosed with selective mutism and their parents 2 years after recovery. Selective mutism (SM) is a rare disorder, and identical twins sharing the condition are extremely rare. The twins developed SM simultaneously during their first year of school. The treatment and follow-up they received for several years are briefly described in this article. The interview explored the children's and their parents' narratives about the origin of the condition, the challenges it entailed in their daily lives, and what they found helpful in the treatment they were offered. In the interview, the children conveyed experiences that even the parents were unaware of and revealed examples of daily life-traumas for which they were unable to obtain support and help. The whole family was trapped in the silence. The twins and their parents emphasized different aspects in terms of what they believed were helpful. The implications of these findings for our understanding and treatment of children with SM are discussed, as well as the potential of service user involvement in child and adolescent mental health research. © The Author(s) 2015.

Ketamine for Pain Management-Side Effects & Potential Adverse Events.

PubMed

Allen, Cheryl A; Ivester, Julius R

2017-12-01

An old anesthetic agent, ketamine is finding new use in lower doses for analgesic purposes. There are concerns stemming from its potential side effects-specifically psychomimetic effects. These side effects are directly related to dose amount. The doses used for analgesic purposes are much lower than those used for anesthesia purposes. A literature review was performed to ascertain potential side effects and/or adverse events when using ketamine for analgesia purposes. The search included CINAHL, PubMed, and Ovid using the search terms "ketamine," "ketamine infusion," "pain," "adverse events," "practice guideline," and "randomized controlled trial." Searches were limited to full-text, peer-reviewed articles and systematic reviews. Initially 1,068 articles were retrieved. The search was then narrowed by using the Boolean connector AND with various search term combinations. After adjusting for duplication, article titles and abstracts were reviewed, leaving 25 articles for an in-depth analysis. Specific exclusion criteria were then applied. The literature supports the use of ketamine for analgesic purposes, and ketamine offers a nonopioid option for the management of some pain conditions. Because ketamine is still classified as an anesthetic agent, health care institutions should develop their own set of policies and protocols for the administration of ketamine. By using forethought and understanding of the properties of ketamine, appropriate care may be planned to mitigate potential side effects and adverse events so that patients are appropriately cared for and their pain effectively managed.

The consumption of electrical and electronic equipment (EEE) is continuously increasing worldwide and, consequently, so is the amount of waste electrical and electronic equipment (WEEE) it generates at its end-of-life. In parallel to this growth, legislation related to this issue has been passed in different countries with the aim of improving the management of WEEE. In order to raise awareness about the situation in which the generation, composition, management or final treatment of this kind of waste currently finds itself, an extensive number of articles have been published around the world. The aim of this paper is to define and analyse the main areas of research on WEEE by offering a broader analysis of the relevant literature in this field published between 1992 and August 2014. The literature researched comprises 307 articles, which are analysed according to the topic they focus on (WEEE management, WEEE generation, WEEE characterisation, social aspects of WEEE, re-use of EEE or economic aspects of WEEE). In addition, a deeper analysis is also presented, which takes into account the temporal evolution (globally and by topic), location of the study, categories and subcategories analysed, etc. © The Author(s) 2014.

Gilbert, F; Cook, M; O'Brien, T; Illes, J

2017-11-11

While new generations of implantable brain computer interface (BCI) devices are being developed, evidence in the literature about their impact on the patient experience is lagging. In this article, we address this knowledge gap by analysing data from the first-in-human clinical trial to study patients with implanted BCI advisory devices. We explored perceptions of self-change across six patients who volunteered to be implanted with artificially intelligent BCI devices. We used qualitative methodological tools grounded in phenomenology to conduct in-depth, semi-structured interviews. Results show that, on the one hand, BCIs can positively increase a sense of the self and control; on the other hand, they can induce radical distress, feelings of loss of control, and a rupture of patient identity. We conclude by offering suggestions for the proactive creation of preparedness protocols specific to intelligent-predictive and advisory-BCI technologies essential to prevent potential iatrogenic harms.

Liu, Bin; Zhang, Ji-Guang; Xu, Wu

Considering the unsatisfied energy density of traditional graphite anode-based lithium (Li)-ion batteries, any alterative high capacity anodes will be highly expected to be practically applied in future high energy battery systems. Li metal is regarded as one of the most promising anodes due to its ultrahigh capacity (3860 mAh g-1), the lowest standard negative electrochemical potential (-3.040 V) and the very low gravimetric density (0.534 g cm-3). However, dendrite growth and high reactivity of Li metal result in low cycling efficiency and severe safety concerns. The revival of research and development on Li metal anode in recent years has broughtmore » new in-depth understandings and key experimental achievements regarding Li metal protection and enhanced performances of Li-metal batteries. In this perspective article, we first concisely review the recent discoveries and then offer possible research directions for further development of Li metal batteries.« less

Method and apparatus for producing a carbon based foam article having a desired thermal-conductivity gradient

DOEpatents

Klett, James W [Knoxville, TN; Cameron, Christopher Stan [Sanford, NC

2010-03-02

A carbon based foam article is made by heating the surface of a carbon foam block to a temperature above its graphitizing temperature, which is the temperature sufficient to graphitize the carbon foam. In one embodiment, the surface is heated with infrared pulses until heat is transferred from the surface into the core of the foam article such that the graphitizing temperature penetrates into the core to a desired depth below the surface. The graphitizing temperature is maintained for a time sufficient to substantially entirely graphitize the portion of the foam article from the surface to the desired depth below the surface. Thus, the foam article is an integral monolithic material that has a desired conductivity gradient with a relatively high thermal conductivity in the portion of the core that was graphitized and a relatively low thermal conductivity in the remaining portion of the foam article.

Developing the field of youth organizing and advocacy: what foundations can do.

PubMed

Yee, Sylvia M

2008-01-01

For more than a decade, the Evelyn and Walter Haas, Jr. Fund has seeded many San Francisco Bay Area youth organizing and advocacy programs. Now that the field is maturing, argues the fund's vice president of programs, foundations have a critical programmatic and capacity-building role to play. The author offers analysis and strategies for integrating youth development grant making across foundation interest areas. The programs described illustrate the diversity of youth organizing and advocacy programs that could be supported by funders, whether or not any particular philanthropic institution has a grant-making focus on youth development or youth organizing. The article ends with an in-depth portrait of the self-reported needs of youth organizing and advocacy programs and concrete strategies for foundations seeking to more effectively enable youth organizing and advocacy to play an important role in bringing about a more vibrant, diverse, and effective democratic culture.

Toxicologists are often called upon to assist in environmental, industrial, occupational and public health assessments. Accordingly, medical toxicologists may find it prudent to be aware of applicable federal toxicological regulations and reporting requirements and of the roles of relevant federal agencies. These regulations are numerous, complex, and have evolved and expanded over time, making it difficult for toxicologists to sustain a current knowledge base. This article reviews the pertinent federal toxicological reporting requirements with regard to the Toxic Substances Control Act (TSCA), the Atomic Energy Act (AEA), the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the Resource Conservation and Recovery Act (RCRA), the Clean Air Act, the Clean Water Act, the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Emergency Planning and Community Right to Know Act (EPCRA), the Occupational Safety and Health Act, the Department of Transportation, and information about the National Response Center. We reference internet-based government resources and offer direct links to applicable websites in an attempt to offer rapid and current sources of practical information. The format of the article is a series of hypothetical scenarios followed by commentary. Discussions of the Safe Drinking Water Act, the Food, Drug, and Cosmetic Act, and the Dietary Supplement Health and Education Act are beyond the scope of this paper. For those desiring a more in-depth discussion of the relevant federal environmental laws and statutes and applicable case law, the reader is directed to resources such as the Environmental Law Handbook, the websites of individual laws found at www.epa.gov and the decisions of individual courts of appeal. It is our hope that this article provides not only useful practical information for the practicing toxicologist but also serves as a key reference for medical toxicology core content on environmental laws and regulations.

Quantitative subsurface analysis using frequency modulated thermal wave imaging

NASA Astrophysics Data System (ADS)

Subhani, S. K.; Suresh, B.; Ghali, V. S.

2018-01-01

Quantitative depth analysis of the anomaly with an enhanced depth resolution is a challenging task towards the estimation of depth of the subsurface anomaly using thermography. Frequency modulated thermal wave imaging introduced earlier provides a complete depth scanning of the object by stimulating it with a suitable band of frequencies and further analyzing the subsequent thermal response using a suitable post processing approach to resolve subsurface details. But conventional Fourier transform based methods used for post processing unscramble the frequencies with a limited frequency resolution and contribute for a finite depth resolution. Spectral zooming provided by chirp z transform facilitates enhanced frequency resolution which can further improves the depth resolution to axially explore finest subsurface features. Quantitative depth analysis with this augmented depth resolution is proposed to provide a closest estimate to the actual depth of subsurface anomaly. This manuscript experimentally validates this enhanced depth resolution using non stationary thermal wave imaging and offers an ever first and unique solution for quantitative depth estimation in frequency modulated thermal wave imaging.

Process cost and facility considerations in the selection of primary cell culture clarification technology.

PubMed

Felo, Michael; Christensen, Brandon; Higgins, John

2013-01-01

The bioreactor volume delineating the selection of primary clarification technology is not always easily defined. Development of a commercial scale process for the manufacture of therapeutic proteins requires scale-up from a few liters to thousands of liters. While the separation techniques used for protein purification are largely conserved across scales, the separation techniques for primary cell culture clarification vary with scale. Process models were developed to compare monoclonal antibody production costs using two cell culture clarification technologies. One process model was created for cell culture clarification by disc stack centrifugation with depth filtration. A second process model was created for clarification by multi-stage depth filtration. Analyses were performed to examine the influence of bioreactor volume, product titer, depth filter capacity, and facility utilization on overall operating costs. At bioreactor volumes <1,000 L, clarification using multi-stage depth filtration offers cost savings compared to clarification using centrifugation. For bioreactor volumes >5,000 L, clarification using centrifugation followed by depth filtration offers significant cost savings. For bioreactor volumes of ∼ 2,000 L, clarification costs are similar between depth filtration and centrifugation. At this scale, factors including facility utilization, available capital, ease of process development, implementation timelines, and process performance characterization play an important role in clarification technology selection. In the case study presented, a multi-product facility selected multi-stage depth filtration for cell culture clarification at the 500 and 2,000 L scales of operation. Facility implementation timelines, process development activities, equipment commissioning and validation, scale-up effects, and process robustness are examined. © 2013 American Institute of Chemical Engineers.

Separate Primary Melanomas of the Bulbar Conjunctiva and Eyelid Skin: Clinical Implications of Multiple Primary Melanomas.

PubMed

Jacinto, Frances A; Fisher, George H; Espana, Edgar M; Leyngold, Ilya M; Margo, Curtis E

2016-10-01

We report a patient with previous in situ melanoma of the forehead skin who was referred for treatment of a bulbar conjunctival melanoma and a separate superficially invasive melanoma of the eyelid skin, and we offer a review of the biological and clinical implications of patients who have multiple primary melanomas. This article offers a clinicopathological correlation with a review of the relevant literature. An 80-year-old white man was referred for evaluation of a suspicious conjunctival tumor and a lower-eyelid lesion. Excisional biopsies revealed that both were primary melanomas arising within in situ disease. Over the span of 25 years, the patient had three separate foci of in situ melanoma, two of which spawned invasive melanoma. Separate melanomas arising from the bulbar conjunctiva and eyelid skin have rarely been reported. Multiple primary melanomas of the skin, however, are not uncommon. Based on studies of persons with multiple cutaneous melanomas, the prognosis is best predicted by the tumor with the greatest depth of invasion. Patients with multiple melanomas should be examined for dysplastic nevi, additional cutaneous melanomas, and screened periodically for future lesions. Ongoing studies enrolling patients with multiple primary melanomas are attempting to generate insights into low-penetrance susceptibility genes.

2011-01-01

Recently, a number of commercial companies are offering preconceptional carrier tests directly-to-consumers. This offer raises a number of concerns and issues above and beyond those encountered with preconceptional tests offered within the traditional health care setting. In order to bring some of these issues to light and to initiate dialogue on this topic, this article discusses the following issues: the current offer of preconceptional carrier tests (until the end of 2010) through online commercial companies; the implications for the informed consent procedure and the need for good information; the need for medical supervision and follow-up; and the appropriate use of existing resources. The article concludes with some reflections about the potential sustainability of the offer of preconceptional carrier tests directly-to-consumers. PMID:21362685

Using GIS and perceived distance to understand the unequal geographies of healthcare in lower-income urban neighbourhoods.

PubMed

Hawthorne, Timothy L; Kwan, Mei-Po

2012-01-01

Geographers play important roles in public health research, particularly in understanding healthcare accessibility, utilisation, and individual healthcare experiences. Most accessibility studies have benefited from the increased sophistication of geographic information systems (GIS). Some studies have been enhanced with semi-structured in-depth interviews to understand individual experiences of people as they access healthcare. However, few accessibility studies have explicitly utilised individual in-depth interview data in the construction of new GIS accessibility measures. Using mixed methods including GIS analysis and individual data from semi-structured in-depth interviews, we offer satisfaction-adjusted distance as a new way of conceptualising accessibility in GIS. Based on fieldwork in a predominantly lower-income community in Columbus, Ohio (USA), we find many residents felt neighbourhood healthcare facilities offered low-quality care, which suggested an added perceived distance as they attempt to access high-quality healthcare facilities. The satisfaction-adjusted distance measure accounts for the perceived distance some residents feel as they search for high-quality healthcare in lower-income urban neighbourhoods. In moving beyond conventional GIS and re-conceptualising accessibility in this way, we offer a more realistic portrayal of the issues lower-income urban residents face as they attempt to access high-quality healthcare facilities. The work has theoretical implications for conceptualising healthcare accessibility, advances the mixed-methodologies literature, and argues for a more equitable distribution of high-quality healthcare in urban neighbourhoods.

Research of detection depth for graphene-based optical sensor

NASA Astrophysics Data System (ADS)

Yang, Yong; Sun, Jialve; Liu, Lu; Zhu, Siwei; Yuan, Xiaocong

2018-03-01

Graphene-based optical sensors have been developed for research into the biological intercellular refractive index (RI) because they offer greater detection depths than those provided by the surface plasmon resonance technique. In this Letter, we propose an experimental approach for measurement of the detection depth in a graphene-based optical sensor system that uses transparent polydimethylsiloxane layers with different thicknesses. The experimental results show that detection depths of 2.5 μm and 3 μm can be achieved at wavelengths of 532 nm and 633 nm, respectively. These results prove that graphene-based optical sensors can realize long-range RI detection and are thus promising for use as tools in the biological cell detection field. Additionally, we analyze the factors that influence the detection depth and provide a feasible approach for detection depth control based on adjustment of the wavelength and the angle of incidence. We believe that this approach will be useful in RI tomography applications.

Ultrasound data for laboratory calibration of an analytical model to calculate crack depth on asphalt pavements.

PubMed

Franesqui, Miguel A; Yepes, Jorge; García-González, Cándida

2017-08-01

This article outlines the ultrasound data employed to calibrate in the laboratory an analytical model that permits the calculation of the depth of partial-depth surface-initiated cracks on bituminous pavements using this non-destructive technique. This initial calibration is required so that the model provides sufficient precision during practical application. The ultrasonic pulse transit times were measured on beam samples of different asphalt mixtures (semi-dense asphalt concrete AC-S; asphalt concrete for very thin layers BBTM; and porous asphalt PA). The cracks on the laboratory samples were simulated by means of notches of variable depths. With the data of ultrasound transmission time ratios, curve-fittings were carried out on the analytical model, thus determining the regression parameters and their statistical dispersion. The calibrated models obtained from laboratory datasets were subsequently applied to auscultate the evolution of the crack depth after microwaves exposure in the research article entitled "Top-down cracking self-healing of asphalt pavements with steel filler from industrial waste applying microwaves" (Franesqui et al., 2017) [1].

Charting ELSI's future course: lessons from the recent past

Walker, Rebecca L.; Morrissey, Clair

2018-01-01

Purpose We sought to examine the ethical, legal, and social implications (ELSI) literature research and scholarship types, topics, and contributing community fields of training as a first step to charting the broader ELSI community’s future priorities and goals. Methods We categorized 642 articles and book chapters meeting inclusion criteria for content in both human genetics or genomics and ethics or ELSI during a 5-year period (2003–2008) according to research and scholarship types, topics, and the area of advanced training of the first-listed author. Research and scholarship type categories were developed and characterized through in-depth review of 95 randomly sampled publications from the larger group. Results There is a single dominant approach to ELSI, which focuses on ethical and other social issues “downstream” of advances in genomics, the contributors to which predominately have advanced training in medicine or science fields other than social science. A comparatively low percentage of publications primarily offer policy recommendations, and these are much more likely to be written by those with advanced training in law than is the case for the literature as a whole. Social science studies predominately employ qualitative methods and vary significantly with respect to the extent and types of recommendations offered. Two further types of ELSI research and scholarship offer alternative models for so-called “normative” work in this field. Conclusion Considering topics, training, and types of ELSI research and scholarship from the most recent past allows for a baseline perspective that is sorely needed in charting this field’s future course.

Therapists' Perspectives on Suicide: A Conceptual Model of Connectedness.

PubMed

Aherne, Cian; Coughlan, Barry; Surgenor, Paul

2017-08-03

A sense of disconnection for people who are suicidal seems to be a key construct of previous literature. Therapists' ways of encountering and understanding people who are suicidal have not been previously researched in depth using qualitative methodologies. The current study aims to develop a theoretical framework for the role played by connectedness in relation to suicide based on the perspectives of psychotherapists working in the field of suicide intervention. Psychotherapists (N = 12) from a suicide intervention service in Ireland were interviewed in relation to connectedness and suicide. The interviews were analysed using Constructivist Grounded Theory. A tentative theoretical model for connectedness in relation to suicide was developed. Therapists view self-disconnect as at the core of suicidality and note that toxic relationships also play a critical role. Therapeutic connection can present as a life-saving paradox for people who are suicidal. Risk of death and therapeutic endeavour may present as challenging dynamics for working with people who are suicidal. Some discussion points include the worth of self-compassion development for people who are suicidal, the rephrasing of "psychotherapy" when trying to save someone's life and the emphasis on relationship skills for all healthcare professionals who encounter people who are suicidal. Clinical or methodological significance of this article: This article is one of the first in which therapists are interviewed about their understandings of suicide and the processes of suicide in the therapeutic space. It offers novel insights about how people who are suicidal present in therapy and what may be contributing to this presentation. The research also gives insights on the struggles for therapists working with people who are suicidal and who may be ambiguous about the prospect of therapy and connecting. The study also offers important direction for future studies in relation to what requires further discussion and exploration regarding engaging in therapy with people who are suicidal. In addition, the current study can offer previously unexplored insights regarding suicide and therapy that may have the potential to assist in future intervention for people who are risk of killing themselves.

Determination of depth-viewing volumes for stereo three-dimensional graphic displays

NASA Technical Reports Server (NTRS)

Parrish, Russell V.; Williams, Steven P.

1990-01-01

Real-world, 3-D, pictorial displays incorporating true depth cues via stereopsis techniques offer a potential means of displaying complex information in a natural way to prevent loss of situational awareness and provide increases in pilot/vehicle performance in advanced flight display concepts. Optimal use of stereopsis requires an understanding of the depth viewing volume available to the display designer. Suggested guidelines are presented for the depth viewing volume from an empirical determination of the effective region of stereopsis cueing (at several viewer-CRT screen distances) for a time multiplexed stereopsis display system. The results provide the display designer with information that will allow more effective placement of depth information to enable the full exploitation of stereopsis cueing. Increasing viewer-CRT screen distances provides increasing amounts of usable depth, but with decreasing fields-of-view. A stereopsis hardware system that permits an increased viewer-screen distance by incorporating larger screen sizes or collimation optics to maintain the field-of-view at required levels would provide a much larger stereo depth-viewing volume.

The Internet has recently made possible the free global availability of scientific journal articles. Open Access (OA) can occur either via OA scientific journals, or via authors posting manuscripts of articles published in subscription journals in open web repositories. So far there have been few systematic studies showing how big the extent of OA is, in particular studies covering all fields of science. The proportion of peer reviewed scholarly journal articles, which are available openly in full text on the web, was studied using a random sample of 1837 titles and a web search engine. Of articles published in 2008, 8.5% were freely available at the publishers' sites. For an additional 11.9% free manuscript versions could be found using search engines, making the overall OA percentage 20.4%. Chemistry (13%) had the lowest overall share of OA, Earth Sciences (33%) the highest. In medicine, biochemistry and chemistry publishing in OA journals was more common. In all other fields author-posted manuscript copies dominated the picture. The results show that OA already has a significant positive impact on the availability of the scientific journal literature and that there are big differences between scientific disciplines in the uptake. Due to the lack of awareness of OA-publishing among scientists in most fields outside physics, the results should be of general interest to all scholars. The results should also interest academic publishers, who need to take into account OA in their business strategies and copyright policies, as well as research funders, who like the NIH are starting to require OA availability of results from research projects they fund. The method and search tools developed also offer a good basis for more in-depth studies as well as longitudinal studies.

2017-09-01

In this article, we explore what enables meaningful participation in a music and theater workshop from a first person's perspective of people with mental health problems. The study uses a hermeneutical-phenomenological approach. Data were collected from qualitative in-depth interviews with 12 participants in a music and theater workshop located in a Norwegian mental health hospital. Data were analyzed through thematic analysis. Two overarching themes were identified: (a) room for dignity and (b) a creative arena. This study indicates that to enable participation for people with long-term mental health problems, it is important to facilitate activities that are flexible, person centered, and resource oriented, in which participants have the possibility to participate regardless of symptoms, functional ability, or whether they are hospitalized. In addition, having professionals who believe in creative growth and offer an illness-free zone that belongs to the participants in a hospital setting is of great importance.

Using qualitative data from 15 in-depth participant interviews and 6-month on-site participant observations as well as a survey result, research revealed the physical, emotional, and social benefits that African American seniors reported as a result of their participation in various activities offered in a multipurpose senior center in Atlanta Georgia. The study presents a social context in which African American seniors constructed their new third age identities that is different from the wide-spread negative images depicted by the mainstream about this minority group. Findings from this study increase the knowledge about African American seniors' participation in multipurpose facilities and provide a better understanding for the diverse socio-economic backgrounds of African American seniors. Study results will have policy implications for a better development of senior centers for minority population in the United States for the promotion of productive and successful aging.

Good teaching requires thoughtful planning and creative thinking, especially when trying to engage students in material that is unfamiliar to them or encumbered by stereotypes, like aging. Classic and contemporary media can provide unique teaching opportunities in gerontology classrooms. Popular films can have a powerful influence over viewers' attitudes and perceptions, and spur in-depth discussions of aging-related topics common to introductory aging courses (e.g., ageism, abuse, inequality, caregiving, healthy aging, and intimate relationships). Additionally, films appeal to multiple learning styles, engaging a variety of learners. This article examines the value of using films in introductory aging courses, offers strategies for incorporating films in the gerontology classroom, suggests sample activities and assignments that pair popular films with aging course topics, identifies challenges of using film in various classrooms settings, and provides a detailed typology of films on each of the following aging topics: ageism and stereotypes, cognitive impairment, death and dying, diversity, family relationships, health and wellness, sexuality and intimacy, and work and retirement.

Leadership is key to quality improvement in nursing homes. This article reports on the initial analysis of the transformational My Home Life Leadership Support program for nursing home managers being implemented in Scotland. It analyses learning from a multimethod participatory descriptive study. Contribution analysis theory informed the evaluation. Evidence-Based Practice, Relationship-Centered Care, Appreciative Inquiry, and Caring Conversations informed the intervention to develop transformational leadership. Data generation methods included baseline and postintervention questionnaires to describe culture change within the study population, together with more in-depth qualitative data generated from group discussions throughout the leadership support program. Qualitative data analysis was an iterative collaborative process with participants to generate themes about the impact of the program on themselves and their practice. Data showed positive changes in managers' perceptions of their self-awareness, leadership communication and relationship skills, and development of positive cultures. This model offers lessons for those interested in ways to approach the emotional, educational, and cultural dynamics of change in other human service contexts.

Black, L F; North, M J

1996-01-01

As the New York Academy of Medicine celebrates its 150th year as a leader in the field of urban health, it is instructive to review the events and decisions that influenced and shaped it. Since its inception, the Academy has taken an active role in lobbying state and local governments to enact more-effective public health laws and in educating the public about improving health conditions. During 1996 and 1997, the Academy Library's Historical Collections is mounting a series of six exhibitions that are intended to tell the story of public health in New York as influenced by the New York Academy of Medicine. The story will be told using printed books, pamphlets, posters, photographs, and manuscripts drawn from the Library's collections, as well as the Academy's archives. Each exhibition will highlight the Academy's accomplishments in the subject areas presented. In this article, we summarize all six of the exhibitions and offer an in-depth look at the first two exhibitions.

Core competencies of the entrepreneurial leader in health care organizations.

Guo, Kristina L

2009-01-01

The purpose of this article is to discuss core competencies that entrepreneurial health care leaders should acquire to ensure the survival and growth of US health care organizations. Three overlapping areas of core competencies are described: (1) health care system and environment competencies, (2) organization competencies, and (3) interpersonal competencies. This study offers insight into the relationship between leaders and entrepreneurship in health care organizations and establishes the foundation for more in-depth studies on leadership competencies in health care settings. The approach for identifying core competencies and designing a competency model is useful for practitioners in leadership positions in complex health care organizations, so that through the understanding and practice of these 3 areas of core competencies, they can enhance their entrepreneurial leadership skills to become more effective health care entrepreneurial leaders. This study can also be used as a tool by health care organizations to better understand leadership performance, and competencies can be used to further the organization's strategic vision and for individual improvement purposes.

2016-01-01

Developing countries have undergone transitions driven by globalization and development, accelerating increases in prevalence of overweight and obesity among children. Schools have been identified as effective settings for interventions that target children's dietary behaviors. In Guatemala, public schools commonly have food kiosks (Casetas) that sell products to children. From July through October 2013, observations during recess, in-depth interviews with school principals (n = 4) and caseta vendors (n = 4), and focus groups with children (n = 48) were conducted. This article explores products available to children at casetas. Factors that affect what casetas offer include regulations and enforcement, vendor investment and earnings, vendor resources, product demand, pricing, and children's preferences. These factors influence the products that are available and children's tendency to purchase them. Potential strategies for improvement include healthy food preparation, price manipulation and promotions, raffles and games to encourage healthier choices, and policy to push toward development of healthier products.

Theorizing fear of crime: beyond the rational/irrational opposition.

PubMed

Lupton, D; Tulloch, J

1999-09-01

Much has been written about the 'social problem' of fear of crime in the criminological and sociological literature in recent years. We would argue that thus far in this literature, however, there has been too much emphasis on the question 'How rational is people's fear of crime?', a question that largely reduces the complexity of the phenomenon and positions a 'biased' lay response against an 'expert' objective judgment. In this article, we review different epistemological perspectives that can be offered to understand in greater depth the fear of crime phenomenon. We place particular emphasis on those hermeneutic perspectives that go beyond the models of the rationalist, individualistic subject to exploring issues of symbolic representation, discourse and the micro - and macro-contexts in which fear of crime is experienced and given meaning. We also draw upon two case studies from our own empirical research into fear of crime, conducted with the intention of exploring the situated narratives, cultural representations and different levels of symbolic meaning that contribute to the dynamic constitution of fear.

This systematic review assessed the literature to evaluate the efficiency of polymerization of bulk-fill composite resins at 4 mm restoration depth. PubMed, Cochrane, Scopus and Web of Science databases were searched with no restrictions on year, publication status, or article's language. Selection criteria included studies that evaluated bulk-fill composite resin when inserted in a minimum thickness of 4 mm, followed by curing according to the manufacturers' instructions; presented sound statistical data; and comparison with a control group and/or a reference measurement of quality of polymerization. The evidence level was evaluated by qualitative scoring system and classified as high-, moderate- and low- evidence level. A total of 534 articles were retrieved in the initial search. After the review process, only 10 full-text articles met the inclusion criteria. Most articles included (80%) were classified as high evidence level. Among several techniques, microhardness was the most frequently method performed by the studies included in this systematic review. Irrespective to the "in vitro" method performed, bulk fill RBCs were partially likely to fulfill the important requirement regarding properly curing in 4 mm of cavity depth measured by depth of cure and / or degree of conversion. In general, low viscosities BFCs performed better regarding polymerization efficiency compared to the high viscosities BFCs.

Controlling neural circuits is a powerful approach to uncover a causal link between neural activity and behaviour. Optogenetics has been widely adopted by the neuroscience community as it offers cell-type-specific perturbation with millisecond precision. However, these studies require light delivery in complex patterns with cellular-scale resolution, while covering a large volume of tissue at depth in vivo. Here we describe a novel high-density silicon-based microscale light-emitting diode (μLED) array, consisting of up to ninety-six 25 μm-diameter μLEDs emitting at a wavelength of 450 nm with a peak irradiance of 400 mW/mm2. A width of 100 μm, tapering to a 1 μm point, and a 40 μm thickness help minimise tissue damage during insertion. Thermal properties permit a set of optogenetic operating regimes, with ~0.5 °C average temperature increase. We demonstrate depth-dependent activation of mouse neocortical neurons in vivo, offering an inexpensive novel tool for the precise manipulation of neural activity.

2016-03-01

The following article identifies new areas for engaged medical anthropological research on health insurance in low- and middle-income countries (LMICs). Based on a review of the literature and pilot research, we identify gaps in how insurance is understood, administered, used, and abused. We provide a historical overview of insurance as an emerging global health panacea and then offer brief assessments of three high-profile attempts to provide universal health coverage. Considerable research on health insurance in LMICs has been quantitative and focused on a limited set of outcomes. To advance the field, we identify eight productive areas for future ethnographic research that will add depth to our understanding of the social life and impact of health insurance in LMICs. Anthropologists can provide unique insights into shifting health and financial practices that accompany insurance coverage, while documenting insurance programs as they evolve and respond to contingencies. © 2015 by the American Anthropological Association.

Training physician-scientists: a model for integrating research into psychiatric residency.

2011-01-01

the number of physicians engaged in research careers has declined significantly over the past two decades. Physicians with in-depth experience and formal training in research design, development, implementation, statistical analysis, and interpretation of scientific information are rare. in response to this shortage, the Medical University of South Carolina (MUSC) launched an NIH-funded research track in 2006 to address the institutional, financial, and regulatory barriers to research training during residency. The primary aim was to incorporate a research track within a 4-year psychiatric residency program for physicians. A secondary goal was to extend recruitment into earlier phases of medical training by offering summer research fellowships to medical and undergraduate students. this article describes the program including core mechanisms of training, recruitment, and outcomes to date. the program provides a model to effectively integrate research training during residency without increasing the number of years of residency training. The training components described herein should be exportable to other psychiatric residency training programs and potentially other specialties of medicine.

A Concept Analysis of Holistic Care by Hybrid Model.

2017-01-01

Even though holistic care has been widely discussed in the health care and professional nursing literature, there is no comprehensive definition of it. Therefore, the aim of this article is to present a concept analysis of holistic care which was developed using the hybrid model. The hybrid model comprises three phases. In the theoretical phase, characteristics of holistic care were identified through a review of the literature from CINAHL, MEDLINE, PubMed, OVID, and Google Scholar databases. During the fieldwork phase, in-depth interviews were conducted with eight nurses who were purposely selected. Finally, following an analysis of the literature and the qualitative interviews, a theoretical description of the concept of holistic care was extracted. Two main themes were extracted of analytical phase: "Holistic care for offering a comprehensive model for caring" and "holistic care for improving patients' and nurses' conditions." By undertaking a conceptual analysis of holistic care, its meaning can be clarified which will encourage nursing educators to include holistic care in nursing syllabi, and consequently facilitate its provision in practice.

This article presents an experiment of water depth inversion using the band ratio method in Dongsha Island shallow water. The remote sensing data is from QuickBird satellite on April 19, 2004. The bathymetry result shows an extensive agreement with the charted depths. 129 points from the chart depth data were chosen to evaluate the accuracy of the inversion depth. The results show that when the water depth is less than 20m, the inversion depth is accord with the chart, while the water depth is more than 20m, the inversion depth is still among 15- 25m. Therefore, the remote sensing methods can only be effective with the inversion of 20m in Dongsha Island shallow water, rather than in deep water area. The total of 109 depth points less than 20m were used to evaluate the accuracy, the root mean square error is 2.2m.

Melendez, Rita M.; Pinto, Rogério M.

2012-01-01

Male-to-female transgender individuals, or transgender women (TW), are at high risk for HIV infection and face multiple barriers to HIV care. Advocates agree that numerous factors need to be addressed concurrently to prevent HIV infection in TW, including primary health care. This article examines how a community-based clinic that offers free or low-cost care addresses the health care needs of TW. A total of 20 TW who attended a health care clinic dedicated to community-based health were interviewed regarding best practices for HIV prevention and primary care. In-depth interviews were conducted, transcribed, coded, and analyzed. Factors reported to be effective for HIV prevention and primary care included (a) access to health care in settings not dedicated to serving transgender and/or gay communities, (b) a friendly atmosphere and staff sensitivity, and (c) holistic care including hormone therapy. Community-based health care settings can be ideal locales for HIV prevention and primary care for TW. PMID:19732697

Distinctive longitudinal narrative data, collected during a critical 18-year period in the history of the HIV epidemic, offer a unique opportunity to examine how young Africans are making sense of evolving developments in HIV prevention and treatment. More than 200,000 young people from across sub-Saharan Africa took part in HIV-themed scriptwriting contests held at eight discrete time points between 1997 and 2014, creating more than 75,000 narratives. This article describes the data reduction and management strategies developed for our cross-national and longitudinal study of these qualitative data. The study aims to inform HIV communication practice by identifying cultural meanings and contextual factors that inform sexual behaviors and social practices, and also to help increase understanding of processes of sociocultural change. We describe our sampling strategies and our triangulating methodologies, combining in-depth narrative analysis, thematic qualitative analysis, and quantitative analysis, which are designed to enable systematic comparison without sacrificing ethnographic richness.

There is an increasingly widespread policy momentum to increase patient-centred care and to improve quality of life outcomes within health services. Qualitative research methods are used to elicit in-depth and detailed insights into people's attitudes, beliefs, emotions and experiences-much of which may remain unspoken during clinical encounters. Questions about patients' beliefs and preferences for treatment can be addressed by qualitative research and inform evidence-based strategies for delivering patient-centred care. Systematic reviews of multiple primary qualitative studies bring together findings from different studies to offer new and more comprehensive understandings of social phenomena across various healthcare contexts and populations and are an emerging methodology in the literature including for care in chronic kidney disease. This article will provide a framework for the systematic review of qualitative research so readers can make sense of these study types and use them in clinical care and policy. © The Author 2014.

Curcumin is a natural polyphenol derived from the plant Curcuma longa, commonly called turmeric. Extensive research over past 50 years has indicated that this polyphenol is highly pleiotropic molecule capable of preventing and treating various cancers. The anticancer potential of Curcumin is severely affected by its limited systemic and target tissue bioavailability and rapid metabolism. In the present review article, we provide a summarized account of different drug delivery systems employed for tackling the problem of curcumin's bioavailability such as liposomes, phospholipid complexes and nanoparticles. Concomitantly we have reviewed the large volume of literature reports describing structural modifications of Curcumin and the anticancer potential of its analogs. Some of the difluorocurcumin analogs allowing longer circulation times and preferential accumulation in the pancreas seem to offer promising leads for conducting first in-depth animal studies and subsequently clinical trials for the use of these analogs for prevention of tumor progression and/or treatments of human malignancies.

2018-06-21

The aim of this study was the baseline description of oil-degrading sediment bacteria along a depth transect in the Faroe-Shetland Channel (FSC) and the identification of biomarker taxa for the detection of oil contamination in FSC sediments. Oil-degrading sediment bacteria from 135, 500 and 1000 m were enriched in cultures with crude oil as the sole carbon source (at 12, 5 and 0°C respectively). The enriched communities were studied using culture-dependent and culture-independent (clone libraries) techniques. Isolated bacterial strains were tested for hydrocarbon degradation capability. Bacterial isolates included well-known oil-degrading taxa and several that are reported in that capacity for the first time (Sulfitobacter, Ahrensia, Belliella, Chryseobacterium). The orders Oceanospirillales and Alteromonadales dominated clone libraries in all stations but significant differences occurred at genus level particularly between the shallow and the deep, cold-water stations. Alcanivorax constituted 64% of clones at FSC135 but was absent at deeper stations. Pseudoalteromonas and Oleispira dominated the bacterial community at 500 and 1000 m. The genus Oleispira emerged as a major player in the early stages of crude oil degradation in deep-sea sediments of the FSC particularly at sub-zero temperatures. This finding is offering a direction for future research into biomonitoring tools for the detection of low levels of crude oil contamination in the deep FSC, and possibly high latitude cold waters in general. Oil and gas exploration in the FSC occurs at depths >1000 m but baseline environmental data necessary for the assessment of ecosystem recovery to pre-spill conditions in the event of an oil spill are lacking. This study will contribute to our ability to assess the impact of oil release in the FSC and guide the direction of bioremediation strategies tailored to the area.

A Parallel Product-Convolution approach for representing the depth varying Point Spread Functions in 3D widefield microscopy based on principal component analysis.

PubMed

2010-03-29

We address the problem of computational representation of image formation in 3D widefield fluorescence microscopy with depth varying spherical aberrations. We first represent 3D depth-dependent point spread functions (PSFs) as a weighted sum of basis functions that are obtained by principal component analysis (PCA) of experimental data. This representation is then used to derive an approximating structure that compactly expresses the depth variant response as a sum of few depth invariant convolutions pre-multiplied by a set of 1D depth functions, where the convolving functions are the PCA-derived basis functions. The model offers an efficient and convenient trade-off between complexity and accuracy. For a given number of approximating PSFs, the proposed method results in a much better accuracy than the strata based approximation scheme that is currently used in the literature. In addition to yielding better accuracy, the proposed methods automatically eliminate the noise in the measured PSFs.

The continuing development of aberration correctors for the scanning transmission electron microscope (STEM) offers the possibility of locating single atoms in crystals in 3D via optical depth sectioning. The main factors that determine the feasibility of such an approach are visibility and dose requirements. In this paper, we show how Poisson's statistics can be quantitatively incorporated into STEM image simulations and demonstrate that the 3D location of single cerium atoms in wurtzite-type aluminum nitride is indeed feasible under large-angle illumination conditions with a relatively low dose. We also show that chromatic aberration does not presently represent a limitation provided amore » cold field emission source is used. Finally, these results suggest efforts into improved aberration corrector designs for larger illumination angles that offer significant potential for 3D structure determination of materials.« less

Loss of the cystic fibrosis transmembrane conductance regulator in cystic fibrosis (CF) leads to hyperabsorption of sodium and fluid from the airway due to upregulation of the epithelial sodium channel (ENaC). Thickened mucus and depleted airway surface liquid (ASL) then lead to impaired mucociliary clearance. ENaC regulation is thus a promising target for CF therapy. Our aim was to develop siRNA nanocomplexes that mediate effective silencing of airway epithelial ENaC in vitro and in vivo with functional correction of epithelial ion and fluid transport. We investigated translocation of nanocomplexes through mucus and their transfection efficiency in primary CF epithelial cells grown at air-liquid interface (ALI).Short interfering RNA (SiRNA)-mediated silencing was examined by quantitative RT-PCR and western analysis of ENaC. Transepithelial potential (V t ), short circuit current (I sc ), ASL depth and ciliary beat frequency (CBF) were measured for functional analysis. Inflammation was analysed by histological analysis of normal mouse lung tissue sections. Nanocomplexes translocated more rapidly than siRNA alone through mucus. Transfections of primary CF epithelial cells with nanocomplexes targeting αENaC siRNA, reduced αENaC and βENaC mRNA by 30%. Transfections reduced V t , the amiloride-sensitive I sc and mucus protein concentration while increasing ASL depth and CBF to normal levels. A single dose of siRNA in mouse lung silenced ENaC by approximately 30%, which persisted for at least 7 days. Three doses of siRNA increased silencing to approximately 50%. Nanoparticle-mediated delivery of ENaCsiRNA to ALI cultures corrected aspects of the mucociliary defect in human CF cells and offers effective delivery and silencing in vivo. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Abstract. In comparison to open surgery, endoscopic surgery offers impaired depth perception and narrower field-of-view. To improve depth perception, the Da Vinci robot offers three-dimensional (3-D) video on the console for the surgeon but not for assistants, although both must collaborate. We improved the shared perception of the whole surgical team by connecting live 3-D monitors to all three available Da Vinci generations, probed user experience after two years by questionnaire, and compared time measurements of a predefined complex interaction task performed with a 3-D monitor versus two-dimensional. Additionally, we investigated whether the complex mental task of reconstructing a 3-D overview from an endoscopic video can be performed by a computer and shared among users. During the study, 925 robot-assisted laparoscopic procedures were performed in three hospitals, including prostatectomies, cystectomies, and nephrectomies. Thirty-one users participated in our questionnaire. Eighty-four percent preferred 3-D monitors and 100% reported spatial-perception improvement. All participating urologists indicated quicker performance of tasks requiring delicate collaboration (e.g., clip placement) when assistants used 3-D monitors. Eighteen users participated in a timing experiment during a delicate cooperation task in vitro. Teamwork was significantly (40%) faster with the 3-D monitor. Computer-generated 3-D reconstructions from recordings offered very wide interactive panoramas with educational value, although the present embodiment is vulnerable to movement artifacts.

How small business health exchanges can offer value to their future customers--and why they must.

PubMed

Kingsdale, Jon

2012-02-01

The success of the Small Business Health Options Program (SHOP)-health insurance exchanges targeted at the small-group market and opening for business in January 2014-will depend in large part on persuading small employers and qualified health plans to participate. The most important objective will be offering employers lower-cost health plans than they have now. Other critical objectives will be offering small firms administrative efficiencies and access to choices among high-value plans that are not offered elsewhere. This article frames the challenges that exchanges will encounter in meeting these objectives. In particular, it discusses the advisability of small-business exchanges' offering an "employee choice" model (which the article describes in detail); of combining the small-business and individual exchanges to broaden product offerings and gain operational efficiencies; and of encouraging low-cost plans to enter the exchange market, perhaps by enabling Medicaid managed care plans to offer comparable commercial products, and in turn affording health plans access to a uniquely motivated market of small firms and their workers who want affordable coverage.

Bispectral Index Monitoring: validity and utility in pediatric dentistry.

PubMed

Goyal, Ashima; Mittal, Neeti; Mittal, Parteek; Gauba, K

2014-01-01

Reliable and safe provision of sedation and general anesthesia is dependent on continuous vigilance of patient's sedation depth. Failure to do so may result in unintended oversedation or undersedation. It is a common practice to observe sedation depth by applying subjective sedation scales and in case of general anesthesia, practitioner is dependent on vital sign assessment. The Bispectral Index System (BIS) is a recently introduced objective, quantitative, easy to use, and free from observer bias, and clinically useful tool to assess sedation depth and it precludes the need to stimulate the patient to assess his sedation level. The present article is an attempt to orient the readers towards utility and validity of BIS for sedation and general anesthesia in pediatric dentistry. In this article, we attempt to make the readers understand the principle of BIS, its variation across sedation continuum, its validity across different age groups and for a variety of sedative drugs.

In modern linacs monitor units should be defined in water at 10 cm depth rather than at dmax.

PubMed

Van den Heuvel, Frank; Wu, Qiuwen; Cai, Jing

2018-05-28

Thanks to the widely adopted guidelines such as AAPM TG-51 1 and IAEA TRS-398 2 , linac calibration has become more consistent and accurate around the globe than previously. Modern linac photon beams are often calibrated in water at 10 cm depth, and configured such that 1 monitor unit (MU) corresponds to 1 cGy at the depth of maximum dose, (d max) . However, such configuration is not without limitations. Some think it is unnecessarily complex and prone to errors, and believe that defining MU at 10 cm is more appropriate. Others think that change of MU definition can cause confusion and possibly serious consequences without any real benefit. This is the premise debated in this month's Point/Counterpoint.

Silos and Social Identity: The Social Identity Approach as a Framework for Understanding and Overcoming Divisions in Health Care

PubMed Central

Kreindler, Sara A; Dowd, Damien A; Dana Star, Noah; Gottschalk, Tania

2012-01-01

Context One of health care's foremost challenges is the achievement of integration and collaboration among the groups providing care. Yet this fundamentally group-related issue is typically discussed in terms of interpersonal relations or operational issues, not group processes. Methods We conducted a systematic search for literature offering a group-based analysis and examined it through the lens of the social identity approach (SIA). Founded in the insight that group memberships form an important part of the self-concept, the SIA encompasses five dimensions: social identity, social structure, identity content, strength of identification, and context. Findings Our search yielded 348 reports, 114 of which cited social identity. However, SIA-citing reports varied in both compatibility with the SIA's metatheoretical paradigm and applied relevance to health care; conversely, some non-SIA-citers offered SIA-congruent analyses. We analyzed the various combinations and interpretations of the five SIA dimensions, identifying ten major conceptual currents. Examining these in the light of the SIA yielded a cohesive, multifaceted picture of (inter)group relations in health care. Conclusions The SIA offers a coherent framework for integrating a diverse, far-flung literature on health care groups. Further research should take advantage of the full depth and complexity of the approach, remain sensitive to the unique features of the health care context, and devote particular attention to identity mobilization and context change as key drivers of system transformation. Our article concludes with a set of “guiding questions” to help health care leaders recognize the group dimension of organizational problems, identify mechanisms for change, and move forward by working with and through social identities, not against them.

2016-05-01

Keeping abreast of trends in the articles and rapidly grasping a body of article's key points and relationship from a holistic perspective is a new challenge in both literature research and text mining. As the important component, keywords can present the core idea of the academic article. Usually, articles on a single theme or area could share one or some same keywords, and we can analyze topological features and evolution of the articles co-keyword networks and keywords co-occurrence networks to realize the in-depth analysis of the articles. This paper seeks to integrate statistics, text mining, complex networks and visualization to analyze all of the academic articles on one given theme, complex network(s). All 5944 ;complex networks; articles that were published between 1990 and 2013 and are available on the Web of Science are extracted. Based on the two-mode affiliation network theory, a new frontier of complex networks, we constructed two different networks, one taking the articles as nodes, the co-keyword relationships as edges and the quantity of co-keywords as the weight to construct articles co-keyword network, and another taking the articles' keywords as nodes, the co-occurrence relationships as edges and the quantity of simultaneous co-occurrences as the weight to construct keyword co-occurrence network. An integrated method for analyzing the topological features and evolution of the articles co-keyword network and keywords co-occurrence networks is proposed, and we also defined a new function to measure the innovation coefficient of the articles in annual level. This paper provides a useful tool and process for successfully achieving in-depth analysis and rapid understanding of the trends and relationships of articles in a holistic perspective.

2015-01-01

Objective. To implement a learner-led, discussion-based course aimed at exposing second-year pharmacy learners to the study of emerging infectious diseases from a global health perspective and to assess the role and importance of pharmacists in the management of disease outbreaks. Design. Learners examined literature pertinent to an emerging infectious disease in a 3-credit, discussion-based course and participated in peer discussion led by a designated learner. Instructional materials included journal articles, audio-visual presentations, documentaries, book chapters, movies, newspaper/magazine articles, and other materials. Learning outcomes were measured based on the ability of learners to perform critical thinking and analysis, communicate with their peers, and participate in class discussions. Assessment. The course was offered to 2 consecutive cohorts consisting of 14 and 16 learners, respectively. Overall, every learner in the first cohort achieved a final grade of A for the course. In the second cohort, the overall grade distribution consisted of grades of A, B, and C for the course. Learner evaluations indicated that the active-learning, discussion-based environment significantly enhanced interest in the topic and overall performance in the course. Conclusion. The elective course on emerging infectious diseases provided in-depth exposure to disease topics normally not encountered in the pharmacy curriculum. Learners found the material and format valuable, and the course enhanced their appreciation of infectious diseases, research methodology, critical thinking and analysis, and their roles as pharmacists.

"Maybe we should talk about it anyway": a qualitative study of understanding expectations and use of an established technology innovation in caring practices.

PubMed

Stokke, Randi

2017-09-15

Technological innovations are strongly promoted to meet the demands posed by increased pressure on home care services and to assist ageing in place in western societies. Although heavily advocated as plug and play solutions, technologies have proven difficult and unpredictable when integrated into home care services. We need greater insight into what happens when technologies are integrated into caring practices. All technologies come with expectations as to their function. This study explores how actors who are involved with the social alarm, which is an established technology innovation, relate to, perceive and articulate these expectations of the technology in everyday living. The article presents results from a two-case study, using a triangulation of qualitative methods in order to gain an in-depth understanding of technology in use in home care services through "thick descriptions". The study was conducted in Norway and data were analysed using a stepwise deductive-inductive analysis. The empirical findings demonstrate that expectations regarding the social alarm, even though it represents a simple and well-established technology, are complex and multidimensional. The notion of script and domestication provided relevant tools for exploring these expectations and for understanding how actors interpret and adapt their practices of using the technology. This enabled a more comprehensive understanding of how technology opens up for different interpretations and puts values in play. This article suggests exploring technology in use as scripted in multidimensional script, and offers a frame for doing so. It also reveals how technology scripts and articulation prove important for understanding the complex reality when integrated into home care practices, thus identifying how using the technology leads to the taming and unleashing of both technology and actors. The study offers an increased understanding of how and why technology is unpredictable and works differently in different contexts. Moreover, it stresses the importance of avoiding expectations of plug-and-play in a reality of complex interactions between different actors.

Interactive Sea Level Rise App & Online Viewer Offers Deep Dive Into Climate

NASA Astrophysics Data System (ADS)

Turrin, M.; Porter, D. F.; Ryan, W. B. F.; Pfirman, S. L.

2015-12-01

Climate has captured the attention of the public but its complexity can cause interested individuals to turn to opinion pieces, news articles or blogs for information. These platforms often oversimplify or present heavily interpreted or personalized perspectives. Data interactives are an extremely effective way to explore complex geoscience topics like climate, opening windows of understanding for the user that have previously been closed. Layering data onto maps through programs like GeoMapApp and the Earth Observer App has allowed users to dig directly into science data, but with only limited scaffolding. The interactive 'Polar Explorer: Sea Level Explorer App' provides a richly layered introduction to a range of topics connected to sea level rise. Each map is supported with a pop up and a short audio file of supplementary material, and an information page that includes the data source and links for further reading. This type of learning platform works well for both the formal and informal learning environment. Through science data displayed as map visualizations the user is invited into topics through an introductory question, such as "Why does sea level change?" After clicking on that question the user moves to a second layer of questions exploring the role of the ocean, the atmosphere, the contribution from the world's glaciers, world's ice sheets and other less obvious considerations such as the role of post-glacial rebound, or the mining of groundwater. Each question ends in a data map, or series of maps, that offer opportunities to interact with the topic. Under the role of the ocean 'Internal Ocean Temperature' offers the user a chance to touch to see temperature values spatially over the world's ocean, or to click through a data series starting at the ocean surface and diving to 5000 meters of depth showing how temperature changes with depth. Other sections, like the role of deglaciation of North America, allow the user to click and see change through time as the Laurentide ice sheet retreated, from 18,000 to 5,000 years ago, changing sea level as it melted. Interacting with the range of topics and the different data layers allows the user to see first hand how climate and sea level have changed through time and how it has, and does, vary around the world.

Semicircular thermocouple needle depth gauge for cryoprocedures.

PubMed

Pappenfort, R B

1981-06-01

A semicircular thermocouple needle depth gauge made of an aluminum alloy drilled with tracks at different angles to place thermocouple needles at various depths below the surface is described herein. Its shape offers definite advantages over circular jigs (templates) when doing cryoexperimentation and when used clinically. The material of which it is made is more durable than plastic. Grommets that firmly snap in place within the inner rim of the instrument permit accurate placement of liquid gas spray, cryoprobes, and other applicators directly over the thermocouple needle tips. This is of special importance when doing cryoexperiments. Furthermore, with this design, the advancing ice front and possible liquid gas runoff are more easily seen. By using both halves it is suitable for monitoring the temperature when freezing large tumors at two different sites and a different depths.

Laser biostimulation therapy planning supported by imaging

NASA Astrophysics Data System (ADS)

Mester, Adam R.

2018-04-01

Ultrasonography and MR imaging can help to identify the area and depth of different lesions, like injury, overuse, inflammation, degenerative diseases. The appropriate power density, sufficient dose and direction of the laser treatment can be optimally estimated. If required minimum 5 mW photon density and required optimal energy dose: 2-4 Joule/cm2 wouldn't arrive into the depth of the target volume - additional techniques can help: slight compression of soft tissues can decrease the tissue thickness or multiple laser diodes can be used. In case of multiple diode clusters light scattering results deeper penetration. Another method to increase the penetration depth is a second pulsation (in kHz range) of laser light. (So called continuous wave laser itself has inherent THz pulsation by temporal coherence). Third solution of higher light intensity in the target volume is the multi-gate technique: from different angles the same joint can be reached based on imaging findings. Recent developments is ultrasonography: elastosonography and tissue harmonic imaging with contrast material offer optimal therapy planning. While MRI is too expensive modality for laser planning images can be optimally used if a diagnostic MRI already was done. Usual DICOM images offer "postprocessing" measurements in mm range.

Comparison of PubMed, Scopus, Web of Science, and Google Scholar: strengths and weaknesses.

PubMed

Falagas, Matthew E; Pitsouni, Eleni I; Malietzis, George A; Pappas, Georgios

2008-02-01

The evolution of the electronic age has led to the development of numerous medical databases on the World Wide Web, offering search facilities on a particular subject and the ability to perform citation analysis. We compared the content coverage and practical utility of PubMed, Scopus, Web of Science, and Google Scholar. The official Web pages of the databases were used to extract information on the range of journals covered, search facilities and restrictions, and update frequency. We used the example of a keyword search to evaluate the usefulness of these databases in biomedical information retrieval and a specific published article to evaluate their utility in performing citation analysis. All databases were practical in use and offered numerous search facilities. PubMed and Google Scholar are accessed for free. The keyword search with PubMed offers optimal update frequency and includes online early articles; other databases can rate articles by number of citations, as an index of importance. For citation analysis, Scopus offers about 20% more coverage than Web of Science, whereas Google Scholar offers results of inconsistent accuracy. PubMed remains an optimal tool in biomedical electronic research. Scopus covers a wider journal range, of help both in keyword searching and citation analysis, but it is currently limited to recent articles (published after 1995) compared with Web of Science. Google Scholar, as for the Web in general, can help in the retrieval of even the most obscure information but its use is marred by inadequate, less often updated, citation information.

Comment on “Empirical determination of depth-distance corrections for mb and MW from Global Seismograph Network Stations” By Guust Nolet, Steve Krueger and Robert M. Clouser

In their recent article, Nolet et al. (1998) presented an analysis which led them to conclude that the epicentral distance and focal depth correction factors for mb which were previously published by Veith and Clawson (1972) are not accurate for events with focal depths greater than 100 km. In this brief commentary, we present some independent evidence which has led us to conclude that the Veith/Clawson (V/C) corrections are in fact quite accurate, at least for seismic events having focal depths of less than about 400 km.

The use of the World Wide Web by medical journals in 2003 and 2005: an observational study.

PubMed

Schriger, David L; Ouk, Sripha; Altman, Douglas G

2007-01-01

The 2- to 6-page print journal article has been the standard for 200 years, yet this format severely limits the amount of detailed information that can be conveyed. The World Wide Web provides a low-cost option for posting extended text and supplementary information. It also can enhance the experience of journal editors, reviewers, readers, and authors through added functionality (eg, online submission and peer review, postpublication critique, and e-mail notification of table of contents.) Our aim was to characterize ways that journals were using the World Wide Web in 2005 and note changes since 2003. We analyzed the Web sites of 138 high-impact print journals in 3 ways. First, we compared the print and Web versions of March 2003 and 2005 issues of 28 journals (20 of which were randomly selected from the 138) to determine how often articles were published Web only and how often print articles were augmented by Web-only supplements. Second, we examined what functions were offered by each journal Web site. Third, for journals that offered Web pages for reader commentary about each article, we analyzed the number of comments and characterized these comments. Fifty-six articles (7%) in 5 journals were Web only. Thirteen of the 28 journals had no supplementary online content. By 2005, several journals were including Web-only supplements in >20% of their papers. Supplementary methods, tables, and figures predominated. The use of supplementary material increased by 5% from 2% to 7% in the 20-journal random sample from 2003 to 2005. Web sites had similar functionality with an emphasis on linking each article to related material and e-mailing readers about activity related to each article. There was little evidence of journals using the Web to provide readers an interactive experience with the data or with each other. Seventeen of the 138 journals offered rapid-response pages. Only 18% of eligible articles had any comments after 5 months. Journal Web sites offer similar functionality. The use of online-only articles and online-only supplements is increasing.

Depth Perception of Surgeons in Minimally Invasive Surgery.

PubMed

Bogdanova, Rositsa; Boulanger, Pierre; Zheng, Bin

2016-10-01

Minimally invasive surgery (MIS) poses visual challenges to the surgeons. In MIS, binocular disparity is not freely available for surgeons, who are required to mentally rebuild the 3-dimensional (3D) patient anatomy from a limited number of monoscopic visual cues. The insufficient depth cues from the MIS environment could cause surgeons to misjudge spatial depth, which could lead to performance errors thus jeopardizing patient safety. In this article, we will first discuss the natural human depth perception by exploring the main depth cues available for surgeons in open procedures. Subsequently, we will reveal what depth cues are lost in MIS and how surgeons compensate for the incomplete depth presentation. Next, we will further expand our knowledge by exploring some of the available solutions for improving depth presentation to surgeons. Here we will review the innovative approaches (multiple 2D camera assembly, shadow introduction) and devices (3D monitors, head-mounted devices, and auto-stereoscopic monitors) for 3D image presentation from the past few years. © The Author(s) 2016.

Combining binary decision tree and geostatistical methods to estimate snow distribution in a mountain watershed

USGS Publications Warehouse

Balk, Benjamin; Elder, Kelly

2000-01-01

We model the spatial distribution of snow across a mountain basin using an approach that combines binary decision tree and geostatistical techniques. In April 1997 and 1998, intensive snow surveys were conducted in the 6.9‐km2 Loch Vale watershed (LVWS), Rocky Mountain National Park, Colorado. Binary decision trees were used to model the large‐scale variations in snow depth, while the small‐scale variations were modeled through kriging interpolation methods. Binary decision trees related depth to the physically based independent variables of net solar radiation, elevation, slope, and vegetation cover type. These decision tree models explained 54–65% of the observed variance in the depth measurements. The tree‐based modeled depths were then subtracted from the measured depths, and the resulting residuals were spatially distributed across LVWS through kriging techniques. The kriged estimates of the residuals were added to the tree‐based modeled depths to produce a combined depth model. The combined depth estimates explained 60–85% of the variance in the measured depths. Snow densities were mapped across LVWS using regression analysis. Snow‐covered area was determined from high‐resolution aerial photographs. Combining the modeled depths and densities with a snow cover map produced estimates of the spatial distribution of snow water equivalence (SWE). This modeling approach offers improvement over previous methods of estimating SWE distribution in mountain basins.

Effect of the depth base along the vertical on the electrical parameters of a vertical parallel silicon solar cell in open and short circuit

NASA Astrophysics Data System (ADS)

Sahin, Gokhan; Kerimli, Genber

2018-03-01

This article presented a modeling study of effect of the depth base initiating on vertical parallel silicon solar cell's photovoltaic conversion efficiency. After the resolution of the continuity equation of excess minority carriers, we calculated the electrical parameters such as the photocurrent density, the photovoltage, series resistance and shunt resistances, diffusion capacitance, electric power, fill factor and the photovoltaic conversion efficiency. We determined the maximum electric power, the operating point of the solar cell and photovoltaic conversion efficiency according to the depth z in the base. We showed that the photocurrent density decreases with the depth z. The photovoltage decreased when the depth base increases. Series and shunt resistances were deduced from electrical model and were influenced and the applied the depth base. The capacity decreased with the depth z of the base. We had studied the influence of the variation of the depth z on the electrical parameters in the base.

IP Subsurface Imaging in the Presence of Buried Steel Infrastructure

NASA Astrophysics Data System (ADS)

Smart, N. H.; Everett, M. E.

2017-12-01

The purpose of this research is to explore the use of induced polarization to image closely-spaced steel columns at a controlled test site. Texas A&M University's Riverside Campus (RELLIS) was used as a control test site to examine the difference between actual and remotely-sensed observed depths. Known borehole depths and soil composition made this site ideal. The subsurface metal structures were assessed using a combination of ER (Electrical Resistivity) and IP (Induced Polarization), and later processed using data inversion. Surveying was set up in reference to known locations and depths of steel structures in order to maximize control data quality. In comparing of known and remotely-sensed foundation depths a series of questions is raised regarding how percent error between imaged and actual depths can be lowered. We are able to draw questions from the results of our survey, as we compare them with the known depth and width of the metal beams. As RELLIS offers a control for us to conduct research, ideal survey geometry and inversion parameters can be met to achieve optimal results and resolution

As pharmacists with a special interest in antimicrobial stewardship, we examine and offer our perspective on advice that is recommended to travellers in terms of prevention, treatment and management of TD with a focus on antibiotic use and resistance. Publications on TD were identified through PubMed, Google Scholar and Cochrane Library databases searches using search terms 'travellers diarrhoea', 'travellers diarrhoea', 'travellers' diarrhoea' 'guidelines', 'expert opinion', 'expert reviews', 'South Asia' and 'South East Asia' (S and SE Asia), 'antibiotics', 'resistance genes', 'travel advice', 'pharmacists', 'guidelines', 'prevention' and 'treatment'. References of articles were also screened for additional relevant studies. Whilst most guidelines and expert reviews were in agreement with the restricted use of antibiotics unless there was a clinical need, the literature review identified gaps in research into behaviours of travellers regarding non-compliance with the pre-travel advice provided and the need for in depth training and education for all healthcare professionals in providing 'tailored' advice for travellers going to high-risk destinations. Travellers should be made aware of the problems of antimicrobial resistance in their destination and home countries and offered alternative forms of prophylaxis for TD. Strategies for prevention of TD, other than the use of antibiotics, also need to be emphasized. All healthcare professionals involved in giving advice about TD should be familiar with the epidemiology of the condition as this will inform responsible behaviours, risk assessment and management strategies in different geographical areas.

LASER APPLICATIONS AND OTHER TOPICS IN QUANTUM ELECTRONICS: Characterisation of optically cleared paper by optical coherence tomography

NASA Astrophysics Data System (ADS)

Fabritius, T.; Alarousu, E.; Prykäri, T.; Hast, J.; Myllylä, Risto

2006-02-01

Due to the highly light scattering nature of paper, the imaging depth of optical methods such as optical coherence tomography (OCT) is limited. In this work, we study the effect of refractive index matching on improving the imaging depth of OCT in paper. To this end, four different refractive index matching liquids (ethanol, 1-pentanol, glycerol and benzyl alcohol) with a refraction index between 1.359 and 1.538 were used in experiments. Low coherent light transmission was studied in commercial copy paper sheets, and the results indicate that benzyl alcohol offers the best improvement in imaging depth, while also being sufficiently stable for the intended purpose. Constructed cross-sectional images demonstrate visually that the imaging depth of OCT is considerably improved by optical clearing. Both surfaces of paper sheets can be detected along with information about the sheet's inner structure.

The Everglades Depth Estimation Network (EDEN) is an integrated network of real-time water-level monitoring, ground-elevation modeling, and water-surface modeling that provides scientists and managers with current (2000-present), online water-stage and water-depth information for the entire freshwater portion of the Greater Everglades. Continuous daily spatial interpolations of the EDEN network stage data are presented on a 400-square-meter grid spacing. EDEN offers a consistent and documented dataset that can be used by scientists and managers to (1) guide large-scale field operations, (2) integrate hydrologic and ecological responses, and (3) support biological and ecological assessments that measure ecosystem responses to the implementation of the Comprehensive Everglades Restoration Plan (CERP) The target users are biologists and ecologists examining trophic level responses to hydrodynamic changes in the Everglades.

Global vision system in laparoscopy.

The main difficulty in laparoscopic or robot-assisted surgery is the narrow visual field, restricted by the endoscope's access port. This restriction is coupled with the difficulty of handling the instruments, which is due not only to the access port but also to the loss of depth of field and perspective due to the lack of natural lighting. In this article, we describe a global vision system and report on our initial experience in a porcine model. The global vision system consists of a series of intraabdominal devices, which increase the visual field and help recover perspective through the simulation of natural shadows. These devices are a series of high-definition cameras and LED lights, which are inserted and fixed to the wall using magnets. The system's efficacy was assessed in a varicocelectomy and nephrectomy. The various intraabdominal cameras offer a greater number of intuitive points of view of the surgical field compared with the conventional telescope and appear to provide a similar view as that in open surgery. Areas previously inaccessible to the standard telescope can now be reached. The additional light sources create shadows that increase the perspective of the surgical field. This system appears to increase the possibilities for laparoscopic or robot-assisted surgery because it offers an instant view of almost the entire abdomen, enabling more complex procedures, which currently require an open pathway.

An overview of health-promoting compounds of broccoli (Brassica oleracea var. italica) and the effect of processing.

PubMed

Mahn, Andrea; Reyes, Alejandro

2012-12-01

Broccoli offers many heath-promoting properties owing to its content of antioxidant and anticarcinogenic compounds. The concentration and bioavailability of polyphenols, glucosinolates, sulforaphane and selenium depend on plant biochemistry, cultivation strategy and type of processing. In this article, the main biochemical properties of broccoli are reviewed regarding their health-promoting effects. Additionally, the way these properties are affected by processing is discussed. Steaming and drying result in an apparent increment of sulforaphane content as well as antioxidant activity, most likely due to an increase of the extractability of antioxidants and sulforaphane. Freezing and boiling diminish polyphenols concentration, mainly due to volatilization and leaching into the cooking water. In view of these results, the optimization of broccoli processing in order to maximize the content of bioactive compounds should be possible. The effect of processing on selenium compounds has been poorly studied so far, and therefore this topic should be investigated in the future. Finally, the effect of operating conditions in different drying processes on the content of bioactive compounds in broccoli should be investigated in a greater depth.

Friction and solid-solid adhesion on complex metallic alloys

PubMed Central

Dubois, Jean-Marie; Belin-Ferré, Esther

2014-01-01

The discovery in 1987 of stable quasicrystals in the Al–Cu–Fe system was soon exploited to patent specific coatings that showed reduced friction in ambient air against hard antagonists. Henceforth, it was possible to develop a number of applications, potential or commercially exploited to date, that will be alluded to in this topical review. A deeper understanding of the characteristics of complex metallic alloys (CMAs) may explain why material made of metals like Al, Cu and Fe offers reduced friction; low solid–solid adhesion came later. It is linked to the surface energy being significantly lower on those materials, in which translational symmetry has become a weak property, that is determined by the depth of the pseudo-gap at the Fermi energy. As a result, friction is anisotropic in CMAs that builds up according to the translation symmetry along one direction, but is aperiodic along the other two directions. A review is given in this article of the most salient data found along these lines during the past two decades or so. PMID:27877675

White matter pathways and social cognition.

Wang, Yin; Metoki, Athanasia; Alm, Kylie H; Olson, Ingrid R

There is a growing consensus that social cognition and behavior emerge from interactions across distributed regions of the "social brain". Researchers have traditionally focused their attention on functional response properties of these gray matter networks and neglected the vital role of white matter connections in establishing such networks and their functions. In this article, we conduct a comprehensive review of prior research on structural connectivity in social neuroscience and highlight the importance of this literature in clarifying brain mechanisms of social cognition. We pay particular attention to three key social processes: face processing, embodied cognition, and theory of mind, and their respective underlying neural networks. To fully identify and characterize the anatomical architecture of these networks, we further implement probabilistic tractography on a large sample of diffusion-weighted imaging data. The combination of an in-depth literature review and the empirical investigation gives us an unprecedented, well-defined landscape of white matter pathways underlying major social brain networks. Finally, we discuss current problems in the field, outline suggestions for best practice in diffusion-imaging data collection and analysis, and offer new directions for future research.

1996-01-01

As the New York Academy of Medicine celebrates its 150th year as a leader in the field of urban health, it is instructive to review the events and decisions that influenced and shaped it. Since its inception, the Academy has taken an active role in lobbying state and local governments to enact more-effective public health laws and in educating the public about improving health conditions. During 1996 and 1997, the Academy Library's Historical Collections is mounting a series of six exhibitions that are intended to tell the story of public health in New York as influenced by the New York Academy of Medicine. The story will be told using printed books, pamphlets, posters, photographs, and manuscripts drawn from the Library's collections, as well as the Academy's archives. Each exhibition will highlight the Academy's accomplishments in the subject areas presented. In this article, we summarize all six of the exhibitions and offer an in-depth look at the first two exhibitions. Images Fig. 1 Fig. 2 Fig. 3 PMID:8982532

"Put your money where your mouth is!": the need for public investment in women's organisations.

PubMed

Riordan, S

2000-03-01

This article explores the inadequate funding of women's organizations, cites examples of their contribution to political processes, and argues the implementation of the political rhetoric of supporting women's organizations. Information was taken from the 1996-99 research, which employed in-depth interviews and gender analysis of records of public funds. At the start of the 21st century, women's organizations have emerged to address the health care, law, child care, education and employment legislation. However, failure of social policy in addressing the priorities of women could be attributed to the lack of acknowledgement among male leaders when making peace agreements. A call for public funding for women's organizations from government agencies was deemed important. Moreover, insufficient funds, understaffing, and marginality to mainstream economic and social development undermines organizational development and capacity to influence political agendas and development policies. In conclusion, monitoring of public investment, deemed as important in realizing women's equality, is necessary in offering opportunity to expose the inadequacy of the investment and find solutions for these problems.

Estimation of fatality and injury risk by means of in-depth fatal accident investigation data.

PubMed

Yannis, George; Papadimitriou, Eleonora; Dupont, Emmanuelle; Martensen, Heike

2010-10-01

In this article the factors affecting fatality and injury risk of road users involved in fatal accidents are analyzed by means of in-depth accident investigation data, with emphasis on parameters not extensively explored in previous research. A fatal accident investigation (FAI) database is used, which includes intermediate-level in-depth data for a harmonized representative sample of 1300 fatal accidents in 7 European countries. The FAI database offers improved potential for analysis, because it includes information on a number of variables that are seldom available, complete, or accurately recorded in road accident databases. However, the fact that only fatal accidents are examined requires for methodological adjustments, namely, the correction for two types of effects on a road user's baseline risk: "accident size" effects, and "relative vulnerability" effects. Fatality and injury risk can be then modeled through multilevel logistic regression models, which account for the hierarchical dependences of the road accident process. The results show that the baseline fatality risk of road users involved in fatal accidents decreases with accident size and increases with the vulnerability of the road user. On the contrary, accident size increases nonfatal injury risk of road users involved in fatal accidents. Other significant effects on fatality and injury risk in fatal accidents include road user age, vehicle type, speed limit, the chain of accident events, vehicle maneuver, and safety equipment. In particular, the presence and use of safety equipment such as seat belt, antilock braking system (ABS), and electronic stability program (ESP) are protection factors for car occupants, especially for those seated at the front seats. Although ABS and ESP systems are typically associated with positive effects on accident occurrence, the results of this research revealed significant related effects on accident severity as well. Moreover, accident consequences are more severe when the most harmful event of the accident occurs later within the accident chain.

Analytical practice: do the new technologies have an impact?

PubMed

Favero, Davide; Candellieri, Stefano

2017-06-01

Through commentary on four clinical vignettes, this article focuses on the anthropological transformations taking place in contemporary society, underlining their differences from the anthropologies of reference of the founding fathers of psychoanalysis. Hybridization between man and machine and the speeding up and alteration of communications which the new technologies promote are now crucial issues facing psychoanalysis. Social media and a 24/7 internet connection have produced deep changes in the way people live and perceive relationships. Analytical practice is not exempt from such issues, which can be particularly insidious, often subtle and difficult to recognize, or even underestimated or ignored by psychoanalysts outright, in order to preserve the illusion of a complete understanding of what unfolds in the analytical space. The authors suggest that such transformations, by (partially) rendering inadequate the theoretical and technical corpus on which the various depth psychologies are founded, require personal engagement on the part of psychoanalysts in the search for new strategies to treat their patients, with the consequent abandonment of the 'certainties' offered by sclerotic models of clinical procedure. © 2017, The Society of Analytical Psychology.

A Concept Analysis of Holistic Care by Hybrid Model

Jasemi, Madineh; Valizadeh, Leila; Zamanzadeh, Vahid; Keogh, Brian

2017-01-01

Purpose: Even though holistic care has been widely discussed in the health care and professional nursing literature, there is no comprehensive definition of it. Therefore, the aim of this article is to present a concept analysis of holistic care which was developed using the hybrid model. Methods: The hybrid model comprises three phases. In the theoretical phase, characteristics of holistic care were identified through a review of the literature from CINAHL, MEDLINE, PubMed, OVID, and Google Scholar databases. During the fieldwork phase, in-depth interviews were conducted with eight nurses who were purposely selected. Finally, following an analysis of the literature and the qualitative interviews, a theoretical description of the concept of holistic care was extracted. Results: Two main themes were extracted of analytical phase: “Holistic care for offering a comprehensive model for caring” and “holistic care for improving patients' and nurses' conditions.” Conclusion: By undertaking a conceptual analysis of holistic care, its meaning can be clarified which will encourage nursing educators to include holistic care in nursing syllabi, and consequently facilitate its provision in practice.

Civil society in a divided society: Linking legitimacy and ethnicness of civil society organizations in Bosnia-Herzegovina

Puljek-Shank, Randall; Verkoren, Willemijn

2016-01-01

Civil society (CS) strengthening is central to peacebuilding policies for divided, post-war societies. However, it has been criticized for creating internationalized organizations without local backing, unable to represent citizens’ interests. Based on in-depth empirical research in Bosnia-Herzegovina, this article focuses on the legitimacy of CS organizations (CSOs). It explores why legitimacy for donors rarely accompanies legitimacy for local actors. We hypothesized that whilst donors avoid supporting mono-ethnic organizations, seen as problematic for peacebuilding, ‘ethnicness’ may provide local legitimacy. However, our analysis of CSOs’ ethnicness nuances research characterizing organizations as either inclusive or divisive. Moreover, local legitimacy is not based on ethnicness per se, but CSOs’ ability to skilfully interact with ethnically divided constituencies and political structures. In addition, we offer novel explanations why few organizations enjoy both donor and local legitimacy, including local mistrust of donors’ normative frameworks and perceived lack of results. However, we also show that a combination of local and donor legitimacy is possible, and explore this rare but interesting category of organizations. PMID:28546640

Experimental analysis of bruises in human volunteers using radiometric depth profiling and diffuse reflectance spectroscopy

NASA Astrophysics Data System (ADS)

Vidovič, Luka; Milanič, Matija; Majaron, Boris

2015-07-01

We combine pulsed photothermal radiometry (PPTR) depth profiling with diffuse reflectance spectroscopy (DRS) measurements for a comprehensive analysis of bruise evolution in vivo. While PPTR enables extraction of detailed depth distribution and concentration profiles of selected absorbers (e.g. melanin, hemoglobin), DRS provides information in a wide range of visible wavelengths and thus offers an additional insight into dynamics of the hemoglobin degradation products. Combining the two approaches enables us to quantitatively characterize bruise evolution dynamics. Our results indicate temporal variations of the bruise evolution parameters in the course of bruise self-healing process. The obtained parameter values and trends represent a basis for a future development of an objective technique for bruise age determination.

To assure smooth program operations and alignment with program objectives, weekly and monthly reports are produced. The weekly report includes metrics on member engagement and utilization for the aforementioned 4 program offerings and reports on the last 4 weeks, as well as for the current month and the current year to date. The monthly report includes separate worksheets for each state and a summary worksheet that includes all states combined, and provides metrics on overall engagement as well as utilization of the 4 program components. Although the monthly reports were used to better manage the 4 program offerings, the weekly reports help management to gauge response to program marketing. Reporting can be a data-driven management tool to help manage wellness programs. Reports provide rapid feedback regarding program performance. In contrast, in-depth program evaluations serve a different purpose, such as to report program-related savings, return on investment, or to report other longer term program-related outcomes.

This article reports a process for rapidly prototyping nanofluidic devices, particularly those comprising slits with microscale widths and nanoscale depths, in silicone. This process consists of designing a nanofluidic device, fabricating a photomask, fabricating a device mold in epoxy photoresist, molding a device in silicone, cutting and punching a molded silicone device, bonding a silicone device to a glass substrate, and filling the device with aqueous solution. By using a bilayer of hard and soft silicone, we have formed and filled nanofluidic slits with depths of less than 400 nm and aspect ratios of width to depth exceeding 250 without collapse of the slits. An important attribute of this article is that the description of this rapid prototyping process is very comprehensive, presenting context and details which are highly relevant to the rational implementation and reliable repetition of the process. Moreover, this process makes use of equipment commonly found in nanofabrication facilities and research laboratories, facilitating the broad adaptation and application of the process. Therefore, while this article specifically informs users of the Center for Nanoscale Science and Technology (CNST) at the National Institute of Standards and Technology (NIST), we anticipate that this information will be generally useful for the nanofabrication and nanofluidics research communities at large, and particularly useful for neophyte nanofabricators and nanofluidicists.

[Violence in social networks: an exploration of the online expressions of teens from marginalized areas of Greater Buenos Aires].

PubMed

Linne, Joaquín Walter; Angilletta, María Florencia

2016-01-01

This paper explores the online expressions of violence perpetrated or experienced by adolescents from marginalized areas of Greater Buenos Aires, Argentina. Using a qualitative methodology, four specific events were examined: threats, "bondis" [fights], cyberbullying and displays of mourning. To do so, 20 in-depth interviews and 3,000 virtual observations of profiles in the social network Facebook were carried out. Among the main results, it was seen that most expressions of violence are part of an offline-online dynamic. Empirical evidence is also offered based upon which it can be affirmed that the expressions of violence of these teenagers are developed around the culture of "aguante" [fierce loyalty]. The article ponders the extent to which, in the iconic platform of the option "like," these expressions are implicitly functional to the social network or, to the contrary, or whether they allow displacements and significant reappropriations on the part of users. New questions arise about the use of these tools by adolescents from marginalized areas and the need for more complex approaches to examine these phenomena.

Physics Back in TIME

Korsunsky, Boris

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.

Articulating addiction in alcohol and other drug policy: A multiverse of habits.

PubMed

Fraser, Suzanne

2016-05-01

Concepts of addiction differ across time and place. This article is based on an international research project currently exploring this variation and change in concepts of addiction, in particular in the field of alcohol and other drug (AOD) use. Taking AOD policy in Australia and Canada as its empirical focus, and in-depth interviews with policy makers, service providers and advocates in each country as its key method (N=60), the article compares the addiction concepts articulated by professionals working in each setting. Drawing on Bruno Latour's theoretical work on the body and his proposal for a better science based on the 'articulation of differences', it explores the accounts of addiction offered across the Australian and Canadian project sites, identifying a shared dynamic in all: the juggling of difference and unity in discussions of the nature of addiction, its composite parts and how best to respond to it. The article maps two simultaneous trajectories in the data - one moving towards difference in participants' insistence on the multitude and diversity of factors that make up addiction problems and solutions, and the other towards unity in their tendency to return to narrow disease models of addiction in uncomfortable, sometimes dissonant, strategic choices. As I will argue, the AOD professionals interviewed for my project operate in two modes treated as distinct in Latour's proposal: in turning to reifying disease labels of addiction they take for granted, and work within, a 'universe of essences', but in articulating the multiplicity and diversity of addiction, they grope towards a vision of a 'multiverse of habits'. The article concludes by addressing this tension directly, scrutinising its practical implications for the development of policy and delivery of services in the future, asking how new thinking, and therefore new opportunities, might be allowed to emerge.

Nanomechanical investigation of ion implanted single crystals - Challenges, possibilities and pitfall traps related to nanoindentation

NASA Astrophysics Data System (ADS)

Kurpaska, Lukasz

2017-10-01

Nanoindentation technique have developed considerably over last thirty years. Nowadays, commercially available systems offer very precise measurement in nano- and microscale, environmental noise cancelling (or at least noise suppressing), in situ high temperature indentation in controlled atmosphere and vacuum conditions and different additional options, among them dedicated indentation is one of the most popular. Due to its high precision, and ability to measure mechanical properties from very small depths (tens of nm), this technique become quite popular in the nuclear society. It is known that ion implantation (to some extent) can simulate the influence of neutron flux. However, depth of the material damage is very limited resulting in creation of thin layer of modified material over unmodified bulk. Therefore, only very precise technique, offering possibility to control depth of the measurement can be used to study functional properties of the material. For this reason, nanoindentation technique seems to be a perfect tool to investigate mechanical properties of ion implanted specimens. However, conducting correct nanomechanical experiment and extracting valuable mechanical parameters is not an easy task. In this paper a discussion about the nanoindentation tests performed on ion irradiated YSZ single crystal is presented. The goal of this paper is to discuss possible traps when studying mechanical properties of such materials and thin coatings.

A novel concept for smart trepanation.

PubMed

Follmann, Axel; Korff, Alexander; Fuertjes, Tobias; Kunze, Sandra C; Schmieder, Kirsten; Radermacher, Klaus

2012-01-01

Trepanation of the skull is a common procedure in craniofacial and neurosurgical interventions, allowing access to the innermost cranial structures. Despite a careful advancement, injury of the dura mater represents a frequent complication during these cranial openings. The technology of computer-assisted surgery offers different support systems such as navigated tools and surgical robots. This article presents a novel technical approach toward an image- and sensor-based synergistic control of the cutting depth of a manually guided soft-tissue-preserving saw. Feasibility studies in a laboratory setup modeling relevant skull tissue parameters demonstrate that errors due to computed tomography or magnetic resonance image segmentation and registration, optical tracking, and mechanical tolerances of up to 2.5 mm, imminent to many computer-assisted surgery systems, can be compensated for by the cutting tool characteristics without damaging the dura. In conclusion, the feasibility of a computer-controlled trepanation system providing a safer and efficient trepanation has been demonstrated. Injuries of the dura mater can be avoided, and the bone cutting gap can be reduced to 0.5 mm with potential benefits for the reintegration of the bone flap.

Modeling the convergence accommodation of stereo vision for binocular endoscopy.

PubMed

Gao, Yuanqian; Li, Jinhua; Li, Jianmin; Wang, Shuxin

2018-02-01

The stereo laparoscope is an important tool for achieving depth perception in robot-assisted minimally invasive surgery (MIS). A dynamic convergence accommodation algorithm is proposed to improve the viewing experience and achieve accurate depth perception. Based on the principle of the human vision system, a positional kinematic model of the binocular view system is established. The imaging plane pair is rectified to ensure that the two rectified virtual optical axes intersect at the fixation target to provide immersive depth perception. Stereo disparity was simulated with the roll and pitch movements of the binocular system. The chessboard test and the endoscopic peg transfer task were performed, and the results demonstrated the improved disparity distribution and robustness of the proposed convergence accommodation method with respect to the position of the fixation target. This method offers a new solution for effective depth perception with the stereo laparoscopes used in robot-assisted MIS. Copyright © 2017 John Wiley & Sons, Ltd.

Apollo 16 double-drive tube 68001 /68002 provides impact and volcanic materials along a depth of approximately 60 cm in five compositional distinct units. 68001 /2 offers the potential to study distinct populations of impact melts with depth to understand how 'gardening' affects these samples. We will use unbiased major-element chemistry, mineralogy, and age to understand the impact history of Apollo 16 landing site. The study demonstrates the techniques that landed missions require to identify lithologies of interest (e.g., impact melts).

The evidence-based practice ideologies.

PubMed

Mantzoukas, Stefanos

2007-10-01

This paper puts forward the argument that there are various, competing, and antithetical evidence-based practice (EBP) definitions and acknowledges that the different EBP definitions are based on different epistemological perspectives. However, this is not enough to understand the way in which nurse professionals choose between the various EBP formations and consequently facilitate them in choosing the most appropriate for their needs. Therefore, the current article goes beyond and behind the various EBP epistemologies to identify how individuals choose an epistemology, which consequently will assist our understanding as to how an individual chooses a specific EBP formation. Individuals choose an epistemology on the mere belief that the specific epistemology offers the ideals or ideas of best explaining or interpreting daily reality. These ideals or ideas are termed by science, history, and politics as ideology. Similarly, individual practitioners choose or should choose between the different EBP formations based on their own personal ideology. Consequently, this article proceeds to analyse the various ideologies behind different EBP definitions as to conclude that there are two broad ideologies that inform the various EBP formations, namely the ideology of truth and the ideology of individual emancipation. These two ideologies are analysed and their connections to the various EBP formations are depicted. Eventually, the article concludes that the in-depth, critical, and intentional analysis by individual nurses of their own ideology will allow them to choose the EBP formation that is most appropriate and fitting for them, and their specific situation. Hence, the conscious analysis of individual ideology becomes the criterion for choosing between competing EBP formations and allows for best evidence to be implemented in practice. Therefore, the best way to teach EBP courses is by facilitating students to analyse their own ideology.

Rhinoplasty: The Asymmetric Crooked Nose-An Overview.

PubMed

Kosins, Aaron M; Daniel, Rollin K; Nguyen, Dananh P

2016-08-01

There are three reasons why the asymmetric crooked nose is one of the greatest challenges in rhinoplasty surgery. First, the complexity of the problem is not appreciated by the patient nor understood by the surgeon. Patients often see the obvious deviation of the nose, but not the distinct differences between the right and left sides. Surgeons fail to understand and to emphasize to the patient that each component of the nose is asymmetric. Second, these deformities can be improved, but rarely made flawless. For this reason, patients are told that the result will be all "-er words," better, straighter, cuter, but no "t-words," there is no perfect nor straight. Most surgeons fail to realize that these cases represent asymmetric noses on asymmetric faces with the variable of ipsilateral and contralateral deviations. Third, these cases demand a wide range of sophisticated surgical techniques, some of which have a minimal margin of error. This article offers an in-depth look at analysis, preoperative planning, and surgical techniques available for dealing with the asymmetric crooked nose.

Lone Actor Terrorist Attack Planning and Preparation: A Data-Driven Analysis.

PubMed

Schuurman, Bart; Bakker, Edwin; Gill, Paul; Bouhana, Noémie

2017-10-23

This article provides an in-depth assessment of lone actor terrorists' attack planning and preparation. A codebook of 198 variables related to different aspects of pre-attack behavior is applied to a sample of 55 lone actor terrorists. Data were drawn from open-source materials and complemented where possible with primary sources. Most lone actors are not highly lethal or surreptitious attackers. They are generally poor at maintaining operational security, leak their motivations and capabilities in numerous ways, and generally do so months and even years before an attack. Moreover, the "loneness" thought to define this type of terrorism is generally absent; most lone actors uphold social ties that are crucial to their adoption and maintenance of the motivation and capability to commit terrorist violence. The results offer concrete input for those working to detect and prevent this form of terrorism and argue for a re-evaluation of the "lone actor" concept. © 2017 The Authors.

2011-12-01

For the needs of snow cover monitoring using multi-source remote sensing data, in the present article, based on the spectrum analysis of different depth and area of snow, the effect of snow depth on the results of snow cover retrieval using normalized difference snow index (NDSI) is discussed. Meanwhile, taking the HJ-1B and MODIS remote sensing data as an example, the snow area effect on the snow cover monitoring is also studied. The results show that: the difference of snow depth does not contribute to the retrieval results, while the snow area affects the results of retrieval to some extents because of the constraints of spatial resolution.

An empirical relationship between PM2.5 and aerosol optical depth in Delhi Metropolitan

PubMed Central

Kumar, Naresh; Chu, Allen; Foster, Andrew

2011-01-01

Atmospheric remote sensing offers a unique opportunity to compute indirect estimates of air quality, which are critically important for the management and surveillance of air quality in megacities of developing countries, particularly in India and China, which have experienced elevated concentration of air pollution but lack adequate spatial–temporal coverage of air pollution monitoring. This article examines the relationship between aerosol optical depth (AOD) estimated from satellite data at 5 km spatial resolution and the mass of fine particles ≤2.5 μm in aerodynamic diameter (PM2.5) monitored on the ground in Delhi Metropolitan where a series of environmental laws have been instituted in recent years. PM2.5 monitored at 113 sites were collocated by time and space with the AOD computed using the data from Moderate Resolution Imaging Spectroradiometer (MODIS onboard the Terra satellite). MODIS data were acquired from NASA’s Goddard Space Flight Center Earth Sciences Distributed Active Archive Center (DAAC). Our analysis shows a significant positive association between AOD and PM2.5. After controlling for weather conditions, a 1% change in AOD explains 0.52±0.202% and 0.39±0.15% change in PM2.5 monitored within ±45 and 150 min intervals of AOD data. This relationship will be used to estimate air quality surface for previous years, which will allow us to examine the time–space dynamics of air pollution in Delhi following recent air quality regulations, and to assess exposure to air pollution before and after the regulations and its impact on health.

The importance of atmospheric correction for airborne hyperspectral remote sensing of shallow waters: application to depth estimation

NASA Astrophysics Data System (ADS)

Castillo-López, Elena; Dominguez, Jose Antonio; Pereda, Raúl; de Luis, Julio Manuel; Pérez, Ruben; Piña, Felipe

2017-10-01

Accurate determination of water depth is indispensable in multiple aspects of civil engineering (dock construction, dikes, submarines outfalls, trench control, etc.). To determine the type of atmospheric correction most appropriate for the depth estimation, different accuracies are required. Accuracy in bathymetric information is highly dependent on the atmospheric correction made to the imagery. The reduction of effects such as glint and cross-track illumination in homogeneous shallow-water areas improves the results of the depth estimations. The aim of this work is to assess the best atmospheric correction method for the estimation of depth in shallow waters, considering that reflectance values cannot be greater than 1.5 % because otherwise the background would not be seen. This paper addresses the use of hyperspectral imagery to quantitative bathymetric mapping and explores one of the most common problems when attempting to extract depth information in conditions of variable water types and bottom reflectances. The current work assesses the accuracy of some classical bathymetric algorithms (Polcyn-Lyzenga, Philpot, Benny-Dawson, Hamilton, principal component analysis) when four different atmospheric correction methods are applied and water depth is derived. No atmospheric correction is valid for all type of coastal waters, but in heterogeneous shallow water the model of atmospheric correction 6S offers good results.

Tracking B-Cell Repertoires and Clonal Histories in Normal and Malignant Lymphocytes.

PubMed

Weston-Bell, Nicola J; Cowan, Graeme; Sahota, Surinder S

2017-01-01

Methods for tracking B-cell repertoires and clonal history in normal and malignant B-cells based on immunoglobulin variable region (IGV) gene analysis have developed rapidly with the advent of massive parallel next-generation sequencing (mpNGS) protocols. mpNGS permits a depth of analysis of IGV genes not hitherto feasible, and presents challenges of bioinformatics analysis, which can be readily met by current pipelines. This strategy offers a potential resolution of B-cell usage at a depth that may capture fully the natural state, in a given biological setting. Conventional methods based on RT-PCR amplification and Sanger sequencing are also available where mpNGS is not accessible. Each method offers distinct advantages. Conventional methods for IGV gene sequencing are readily adaptable to most laboratories and provide an ease of analysis to capture salient features of B-cell use. This chapter describes two methods in detail for analysis of IGV genes, mpNGS and conventional RT-PCR with Sanger sequencing.

Connected Audiological Rehabilitation: 21st Century Innovations

PubMed Central

Saunders, Gabrielle H.; Chisolm, Theresa H.

2016-01-01

Background Tele-audiology provides a means to offer audiologic rehabilitation (AR) in a cost-, resource-, and time-effective manner. If designed appropriately, it also has the capability of personalizing rehabilitation to the user in terms of content, depth of detail, etc., thus permitting selection of the best content for a particular individual. Synchronous/real-time data collection, store and forward telehealth, remote monitoring and mobile health using smartphone applications have each been applied to components of audiologic rehabilitation intervention (sensory management, instruction in the use of technology and control of the listening environment, perceptual and communication strategies training, and counseling). In this article, the current state of tele-audiological rehabilitation interventions are described and discussed. Results The provision of AR via tele-audiology potentially provides a cost-effective mechanism for addressing barriers to the routine provision of AR beyond provisions of hearing technology. Furthermore, if designed appropriately, it has the capability of personalizing rehabilitation to the user in terms of content, depth of detail, etc., thus permitting selection of the best content for a particular individual. However, effective widespread implementation of tele-audiology will be dependent on good education of patients and clinician alike, and researchers must continue to examine the effectiveness of these new approaches to AR in order to ensure clinicians provide effective evidence-based rehabilitation to their patients. Conclusions While several barriers to the widespread use of tele-audiology for audiologic rehabilitation currently exist, it is concluded that through education of patients and clinicians alike, it will gain greater support from practitioners and patients over time and will become successfully and widely implemented.

Volumetric 3D display using a DLP projection engine

NASA Astrophysics Data System (ADS)

Geng, Jason

2012-03-01

In this article, we describe a volumetric 3D display system based on the high speed DLPTM (Digital Light Processing) projection engine. Existing two-dimensional (2D) flat screen displays often lead to ambiguity and confusion in high-dimensional data/graphics presentation due to lack of true depth cues. Even with the help of powerful 3D rendering software, three-dimensional (3D) objects displayed on a 2D flat screen may still fail to provide spatial relationship or depth information correctly and effectively. Essentially, 2D displays have to rely upon capability of human brain to piece together a 3D representation from 2D images. Despite the impressive mental capability of human visual system, its visual perception is not reliable if certain depth cues are missing. In contrast, volumetric 3D display technologies to be discussed in this article are capable of displaying 3D volumetric images in true 3D space. Each "voxel" on a 3D image (analogous to a pixel in 2D image) locates physically at the spatial position where it is supposed to be, and emits light from that position toward omni-directions to form a real 3D image in 3D space. Such a volumetric 3D display provides both physiological depth cues and psychological depth cues to human visual system to truthfully perceive 3D objects. It yields a realistic spatial representation of 3D objects and simplifies our understanding to the complexity of 3D objects and spatial relationship among them.

Rethinking responsibility in offenders with acquired paedophilia: punishment or treatment?

PubMed

Gilbert, Frédéric; Focquaert, Farah

2015-01-01

This article reviews the current neurobiological literature on the aetiology of developmental and acquired paedophilia and examines what the consequences could be in terms of responsibility and treatment for the latter. Addressing the question of responsibility and punishment of offenders with acquired paedophilia from a neurobiological perspective is controversial. Consequently it is essential to avoid hasty conclusions based strictly on neurobiological abnormality justifications. This study establishes a distinction between developmental and acquired paedophilia. The article investigates whether offenders who fulfil the diagnosis of acquired paedophilia should be held fully responsible, particularly in cases where the offender's conduct appears to result from volitionally controlled behaviour that is seemingly incompatible with a neurological cause. Moreover, the article explores how responsibility can be compromised when offenders with acquired paedophilia have (partially) preserved moral knowledge despite their sexual disorder. The article then examines the option of offering mandatory treatment as an alternative to imprisonment for offenders with acquired paedophilia. Furthermore, the article addresses the ethical issues related to offering any form of quasi-coercive treatment as a condition of release. This study concludes that decisions to fully or partially excuse an individual who fulfil the diagnosis of acquired paedophilia should take all relevant information into account, both neurobiological and other environmental evidence, and should proceed on a careful case by case analysis before sentencing or offering treatment.

Qualitative and mixed methods in mental health services and implementation research.

PubMed

Palinkas, Lawrence A

2014-01-01

Qualitative and mixed methods play a prominent role in mental health services research. However, the standards for their use are not always evident, especially for those not trained in such methods. This article reviews the rationale and common approaches to using qualitative and mixed methods in mental health services and implementation research based on a review of the articles included in this special series along with representative examples from the literature. Qualitative methods are used to provide a "thick description" or depth of understanding to complement breadth of understanding afforded by quantitative methods, elicit the perspective of those being studied, explore issues that have not been well studied, develop conceptual theories or test hypotheses, or evaluate the process of a phenomenon or intervention. Qualitative methods adhere to many of the same principles of scientific rigor as quantitative methods but often differ with respect to study design, data collection, and data analysis strategies. For instance, participants for qualitative studies are usually sampled purposefully rather than at random and the design usually reflects an iterative process alternating between data collection and analysis. The most common techniques for data collection are individual semistructured interviews, focus groups, document reviews, and participant observation. Strategies for analysis are usually inductive, based on principles of grounded theory or phenomenology. Qualitative methods are also used in combination with quantitative methods in mixed-method designs for convergence, complementarity, expansion, development, and sampling. Rigorously applied qualitative methods offer great potential in contributing to the scientific foundation of mental health services research.

1999-01-01

Regarding the debate on the existence of two current focuses on health science research (qualitative and quantitative), the paper states the need for complementing the techniques which contribute to a better knowledge of populations and communities, and the need for offering effective solutions to different problems. The article analyses the usefulness of qualitative methods, describes the techniques and procedures more frequently used to guarantee the validity and reliability of research findings and ends bringing up the need for using qualitative and quantitative approaches. This way of working together or learning from each other will enrich research and interventions on public heath and health management fields. Qualitative methods are useful for sound understanding of a given issue that is being investigated or evaluated taking into account the point of view of the participants under research. Key techniques, listed from the most structured to the less structured are among others: structured interview, Delphi, nominal group, case study, semistructured interview, focal group, brainstorming, discussion group, in depth interview, life story and participant observation.

Constructing Patient Stories: ‘Dynamic’ Case Notes and Clinical Encounters at Glasgow’s Gartnavel Mental Hospital, 1921–32

PubMed Central

Morrison, Hazel

2016-01-01

This article contextualises the production of patient records at Glasgow’s Gartnavel Mental Hospital between 1921 and 1932. Following his appointment as asylum superintendent in 1921, psychiatrist David Kennedy Henderson sought to introduce a so-called dynamic approach to mental health care. He did so, primarily, by encouraging patients to reveal their inner lives through their own language and own understanding of their illness. To this effect, Henderson implemented several techniques devised to gather as much information as possible about patients. He notably established routine ‘staff meetings’ in which a psychiatrist directed questions towards a patient while a stenographer recorded word-for-word the conversation that passed between the two parties. As a result, the records compiled at Gartnavel under Henderson’s guidance offer a unique window into the various strategies deployed by patients, but also allow physicians and hospital staff to negotiate their place amidst these clinical encounters. In this paper, I analyse the production of patient narratives in these materials. The article begins with Henderson’s articulation of his ‘dynamic’ psychotherapeutic method, before proceeding to an in-depth hermeneutic investigation into samples of Gartnavel’s case notes and staff meeting transcripts. In the process, patient–psychiatrist relationships are revealed to be mutually dependent and interrelated subjects of historical enquiry rather than as distinct entities. This study highlights the multi-vocal nature of the construction of stories ‘from below’ and interrogates their subsequent appropriation by historians. PMID:26651189

In pursuit of goodness in bioethics: analysis of an exemplary article.

PubMed

Hofmann, Bjørn; Magelssen, Morten

2018-06-15

What is good bioethics? Addressing this question is key for reinforcing and developing the field. In particular, a discussion of potential quality criteria can heighten awareness and contribute to the quality of bioethics publications. Accordingly, the objective of this article is threefold: first, we want to identify a set of criteria for quality in bioethics. Second, we want to illustrate the added value of a novel method: in-depth analysis of a single article with the aim of deriving quality criteria. The third and ultimate goal is to stimulate a broad and vivid debate on goodness in bioethics. An initial literature search reveals a range of diverse quality criteria. In order to expand on the realm of such quality criteria, we perform an in-depth analysis of an article that is acclaimed for being exemplary. The analysis results in eleven specific quality criteria for good bioethics in three categories: argumentative, empirical, and dialectic. Although we do not claim that the identified criteria are universal or absolute, we argue that they are fruitful for fueling a continuous constitutive debate on what is "good bioethics." Identifying, debating, refining, and applying such criteria is an important part of defining and improving bioethics.

Optimization of Variable-Depth Liner Configurations for Increased Broadband Noise Reduction

NASA Technical Reports Server (NTRS)

Jones, M. G.; Watson, W. R.; Nark, D. M.; Schiller, N. H.; Born, J. C.

2016-01-01

This paper employs three acoustic propagation codes to explore variable-depth liner configurations for the NASA Langley Grazing Flow Impedance Tube (GFIT). The initial study demonstrates that a variable impedance can acceptably be treated as a uniform impedance if the spatial extent over which this variable impedance occurs is less than one-third of a wavelength of the incident sound. A constrained optimization study is used to design a variable-depth liner and to select an optimization metric. It also provides insight regarding how much attenuation can be achieved with variable-depth liners. Another optimization study is used to design a liner with much finer chamber depth resolution for the Mach 0.0 and 0.3 test conditions. Two liners are designed based on spatial rearrangement of chambers from this liner to determine whether the order is critical. Propagation code predictions suggest this is not the case. Both liners are fabricated via additive manufacturing and tested in the GFIT for the Mach 0.0 condition. Predicted and measured attenuations compare favorably across the full frequency range. These results clearly suggest that the chambers can be arranged in any order, thus offering the potential for innovative liner designs to minimize depth and weight.

Stereoscopic depth constancy

PubMed Central

Guan, Phillip

2016-01-01

Depth constancy is the ability to perceive a fixed depth interval in the world as constant despite changes in viewing distance and the spatial scale of depth variation. It is well known that the spatial frequency of depth variation has a large effect on threshold. In the first experiment, we determined that the visual system compensates for this differential sensitivity when the change in disparity is suprathreshold, thereby attaining constancy similar to contrast constancy in the luminance domain. In a second experiment, we examined the ability to perceive constant depth when the spatial frequency and viewing distance both changed. To attain constancy in this situation, the visual system has to estimate distance. We investigated this ability when vergence, accommodation and vertical disparity are all presented accurately and therefore provided veridical information about viewing distance. We found that constancy is nearly complete across changes in viewing distance. Depth constancy is most complete when the scale of the depth relief is constant in the world rather than when it is constant in angular units at the retina. These results bear on the efficacy of algorithms for creating stereo content. This article is part of the themed issue ‘Vision in our three-dimensional world’. PMID:27269596

An active vanadium dioxide integrated metasurface offering broadband transmitted terahertz wave modulation with large modulation-depth under electrical control is demonstrated. The device consists of metal bias-lines arranged with grid-structure patterned vanadium dioxide (VO 2 ) film on sapphire substrate. Amplitude transmission is continuously tuned from more than 78% to 28% or lower in the frequency range from 0.3 THz to 1.0 THz, by means of electrical bias at temperature of 68 °C. The physical mechanism underlying the device's electrical tunability is investigated and found to be attributed to the ohmic heating. The developed device possessing over 87% modulation depth with 0.7 THz frequency band is expected to have many potential applications in THz regime such as tunable THz attenuator.

Effects of cortical damage on binocular depth perception.

PubMed

Bridge, Holly

2016-06-19

Stereoscopic depth perception requires considerable neural computation, including the initial correspondence of the two retinal images, comparison across the local regions of the visual field and integration with other cues to depth. The most common cause for loss of stereoscopic vision is amblyopia, in which one eye has failed to form an adequate input to the visual cortex, usually due to strabismus (deviating eye) or anisometropia. However, the significant cortical processing required to produce the percept of depth means that, even when the retinal input is intact from both eyes, brain damage or dysfunction can interfere with stereoscopic vision. In this review, I examine the evidence for impairment of binocular vision and depth perception that can result from insults to the brain, including both discrete damage, temporal lobectomy and more systemic diseases such as posterior cortical atrophy.This article is part of the themed issue 'Vision in our three-dimensional world'. © 2016 The Authors.

Comparison of Decisions Quality of Heuristic Methods with Limited Depth-First Search Techniques in the Graph Shortest Path Problem

NASA Astrophysics Data System (ADS)

Vatutin, Eduard

2017-12-01

The article deals with the problem of analysis of effectiveness of the heuristic methods with limited depth-first search techniques of decision obtaining in the test problem of getting the shortest path in graph. The article briefly describes the group of methods based on the limit of branches number of the combinatorial search tree and limit of analyzed subtree depth used to solve the problem. The methodology of comparing experimental data for the estimation of the quality of solutions based on the performing of computational experiments with samples of graphs with pseudo-random structure and selected vertices and arcs number using the BOINC platform is considered. It also shows description of obtained experimental results which allow to identify the areas of the preferable usage of selected subset of heuristic methods depending on the size of the problem and power of constraints. It is shown that the considered pair of methods is ineffective in the selected problem and significantly inferior to the quality of solutions that are provided by ant colony optimization method and its modification with combinatorial returns.

Evaluating the potential for remote bathymetric mapping of a turbid, sand-bed river: 1. field spectroscopy and radiative transfer modeling

USGS Publications Warehouse

Legleiter, Carl J.; Kinzel, Paul J.; Overstreet, Brandon T.

2011-01-01

Remote sensing offers an efficient means of mapping bathymetry in river systems, but this approach has been applied primarily to clear-flowing, gravel bed streams. This study used field spectroscopy and radiative transfer modeling to assess the feasibility of spectrally based depth retrieval in a sand-bed river with a higher suspended sediment concentration (SSC) and greater water turbidity. Attenuation of light within the water column was characterized by measuring the amount of downwelling radiant energy at different depths and calculating a diffuse attenuation coefficient, Kd. Attenuation was strongest in blue and near-infrared bands due to scattering by suspended sediment and absorption by water, respectively. Even for red wavelengths with the lowest values of Kd, only a small fraction of the incident light propagated to the bed, restricting the range of depths amenable to remote sensing. Spectra recorded above the water surface were used to establish a strong, linear relationship (R2 = 0.949) between flow depth and a simple band ratio; even under moderately turbid conditions, depth remained the primary control on reflectance. Constraints on depth retrieval were examined via numerical modeling of radiative transfer within the atmosphere and water column. SSC and sensor radiometric resolution limited both the maximum detectable depth and the precision of image-derived depth estimates. Thus, although field spectra indicated that the bathymetry of turbid channels could be remotely mapped, model results implied that depth retrieval in sediment-laden rivers would be limited to shallow depths (on the order of 0.5 m) and subject to a significant degree of uncertainty.

A perspective on high-frequency ultrasound for medical applications

NASA Astrophysics Data System (ADS)

Mamou, Jonathan; Aristizába, Orlando; Silverman, Ronald H.; Ketterling, Jeffrey A.

2010-01-01

High-frequency ultrasound (HFU, >15 MHz) is a rapidly developing field. HFU is currently used and investigated for ophthalmologic, dermatologic, intravascular, and small-animal imaging. HFU offers a non-invasive means to investigate tissue at the microscopic level with resolutions often better than 100 μm. However, fine resolution is only obtained over the limited depth-of-field (˜1 mm) of single-element spherically-focused transducers typically used for HFU applications. Another limitation is penetration depth because most biological tissues have large attenuation at high frequencies. In this study, two 5-element annular arrays with center frequencies of 17 and 34 MHz were fabricated and methods were developed to obtain images with increased penetration depth and depth-of-field. These methods were used in ophthalmologic and small-animal imaging studies. Improved blood sensitivity was obtained when a phantom mimicking a vitreous hemorrhage was imaged. Central-nervous systems of 12.5-day-old mouse embryos were imaged in utero and in three dimensions for the first time.

Owens, Bramer

2005-01-01

Recent controversies in the hospital sector have questioned whether the levels of charity care, community benefit, and executive compensation provided by not-for-profit hospitals are consistent with mandates of their tax-exempt status and mission statements. This article demonstrates that these recent controversies stem from a combination of historical influences, regulatory inequities, and competitive disadvantages, which are suffocating many not-for-profit hospitals across the nation. Once the current environment is described, the article discusses each threat and offers actionable recommendations to quell current attacks faced by the industry. First, to address the current probe by the Internal Revenue Service, hospitals must begin to link their executive compensation with their organizational mission. Second, to address recent lawsuits, the article presents a standardized definition of community benefit and recommends an alternative model to classify charity care. Finally, to address recent congressional hearings, the article offers a plan for hospitals to gauge their expected benefit to the community they serve.

A century of Gestalt psychology in visual perception: I. Perceptual grouping and figure-ground organization.

2012-11-01

In 1912, Max Wertheimer published his paper on phi motion, widely recognized as the start of Gestalt psychology. Because of its continued relevance in modern psychology, this centennial anniversary is an excellent opportunity to take stock of what Gestalt psychology has offered and how it has changed since its inception. We first introduce the key findings and ideas in the Berlin school of Gestalt psychology, and then briefly sketch its development, rise, and fall. Next, we discuss its empirical and conceptual problems, and indicate how they are addressed in contemporary research on perceptual grouping and figure-ground organization. In particular, we review the principles of grouping, both classical (e.g., proximity, similarity, common fate, good continuation, closure, symmetry, parallelism) and new (e.g., synchrony, common region, element and uniform connectedness), and their role in contour integration and completion. We then review classic and new image-based principles of figure-ground organization, how it is influenced by past experience and attention, and how it relates to shape and depth perception. After an integrated review of the neural mechanisms involved in contour grouping, border ownership, and figure-ground perception, we conclude by evaluating what modern vision science has offered compared to traditional Gestalt psychology, whether we can speak of a Gestalt revival, and where the remaining limitations and challenges lie. A better integration of this research tradition with the rest of vision science requires further progress regarding the conceptual and theoretical foundations of the Gestalt approach, which is the focus of a second review article.

The earnings game. Everyone plays, nobody wins.

PubMed

Collingwood, H

2001-06-01

Quarterly earnings numbers dominate the decisions of executives, analysts, investors, and auditors. Yet for all the attention paid to these numbers, they're not much use in predicting a company's future performance and cash flows. Even economists are unanimous in their view that these numbers say next to nothing about a company's prospects beyond the next quarter. Nonetheless, meetings analysts' expectations that earnings will rise in a smooth, steady, unbroken line has become, at many corporations, a game whose imperatives override even the imperative to deliver the highest possible return to shareholders. The fetishistic attention paid to this almost meaningless indicator might be cause for amusement, except for one thing: the earnings game does real harm. It distorts corporate decision making. It reduces securities analysis and investing to a guessing contest. It compromises the integrity of corporate audits. Ultimately, it undermines the capital markets. As market participants increasingly come to view the quarterly number as a sort of collective fiction, offered and received in a spirit of mutual cynicism, they lose faith in the numbers affected by quarterly earnings--including stock prices themselves. And no market can survive long if its participants see no connection between prices and the intrinsic value of the goods on offer. In this article, HBR senior editor Harris Collingwood takes an in-depth look at these effects, examining the intricacies of the earnings game and why companies believe they have no choice but to play it. Until more corporate executives change their practices, he explains, the earning game will never lack for players.

Photoacoustic imaging with planoconcave optical microresonator sensors: feasibility studies based on phantom imaging

NASA Astrophysics Data System (ADS)

Guggenheim, James A.; Zhang, Edward Z.; Beard, Paul C.

2017-03-01

The planar Fabry-Pérot (FP) sensor provides high quality photoacoustic (PA) images but beam walk-off limits sensitivity and thus penetration depth to ≍1 cm. Planoconcave microresonator sensors eliminate beam walk-off enabling sensitivity to be increased by an order-of-magnitude whilst retaining the highly favourable frequency response and directional characteristics of the FP sensor. The first tomographic PA images obtained in a tissue-realistic phantom using the new sensors are described. These show that the microresonator sensors provide near identical image quality as the planar FP sensor but with significantly greater penetration depth (e.g. 2-3cm) due to their higher sensitivity. This offers the prospect of whole body small animal imaging and clinical imaging to depths previously unattainable using the FP planar sensor.

Byer, R. L.

1975-01-01

This paper presents a discussion and comparison of the Raman method, the resonance and fluorescence backscatter method, long path absorption methods and the differential absorption method for remote air pollution measurement. A comparison of the above remote detection methods shows that the absorption methods offer the most sensitivity at the least required transmitted energy. Topographical absorption provides the advantage of a single ended measurement, and differential absorption offers the additional advantage of a fully depth resolved absorption measurement. Recent experimental results confirming the range and sensitivity of the methods are presented.

Improving Bridging from Informatics Practice to Theory.

Lehmann, C U; Gundlapalli, A V

2015-01-01

In 1962, Methods of Information in Medicine ( MIM ) began to publish papers on the methodology and scientific fundamentals of organizing, representing, and analyzing data, information, and knowledge in biomedicine and health care. Considered a companion journal, Applied Clinical Informatics ( ACI ) was launched in 2009 with a mission to establish a platform that allows sharing of knowledge between clinical medicine and health IT specialists as well as to bridge gaps between visionary design and successful and pragmatic deployment of clinical information systems. Both journals are official journals of the International Medical Informatics Association. As a follow-up to prior work, we set out to explore congruencies and interdependencies in publications of ACI and MIM. The objectives were to describe the major topics discussed in articles published in ACI in 2014 and to determine if there was evidence that theory in 2014 MIM publications was informed by practice described in ACI publications in any year. We also set out to describe lessons learned in the context of bridging informatics practice and theory and offer opinions on how ACI editorial policies could evolve to foster and improve such bridging. We conducted a retrospective observational study and reviewed all articles published in ACI during the calendar year 2014 (Volume 5) for their main theme, conclusions, and key words. We then reviewed the citations of all MIM papers from 2014 to determine if there were references to ACI articles from any year. Lessons learned in the context of bridging informatics practice and theory and opinions on ACI editorial policies were developed by consensus among the two authors. A total of 70 articles were published in ACI in 2014. Clinical decision support, clinical documentation, usability, Meaningful Use, health information exchange, patient portals, and clinical research informatics emerged as major themes. Only one MIM article from 2014 cited an ACI article. There are several lessons learned including the possibility that there may not be direct links between MIM theory and ACI practice articles. ACI editorial policies will continue to evolve to reflect the breadth and depth of the practice of clinical informatics and articles received for publication. Efforts to encourage bridging of informatics practice and theory may be considered by the ACI editors. The lack of direct links from informatics theory-based papers published in MIM in 2014 to papers published in ACI continues as was described for papers published during 2012 to 2013 in the two companion journals. Thus, there is little evidence that theory in MIM has been informed by practice in ACI.

Social service programmes that offer consumer choices are intended to guide service efficiency and customer satisfaction. However, little is known about how social service consumers actually make choices and how providers deliver such services. This article details the practical implementation of consumer choice in a Canadian workers' compensation vocational retraining programme. Discourse analysis was conducted of in-depth interviews and focus groups with 71 injured workers and service providers, who discussed their direct experience of a vocational retraining system. Data also included procedural, policy and administrative documents. Consumer choice included workers being offered choices about some service aspects, but not being able to exercise meaningful discretion. Programme cost objectives and restrictive rules and bureaucracy skewed the guidance provided to workers by service providers. If workers did not make the "right" choices, then the service providers were required to make choices for them. This upset workers and created tension for service providers. The ideal of consumer choice in a social service programme was difficult to enact, both for workers and service providers. Processes to increase quality of guidance to social service consumers and to create a systematic feedback look between system designers and consumers are recommended. Implications for Rehabilitation Consumer choice is an increasingly popular concept in social service systems. Vocational case managers can have their own administrative needs and tensions, which do not always align with the client's choices. Rehabilitation programmes need to have processes for considering what choices are important to clients and the resources to support them.

Emerging mobile technologies offer nursing faculty a broader armamentarium with which to support traditionally at-risk students. Podcasting, a type of mobile learning, uses technology that allows students to access and listen to recorded classroom audio files from a computer, MP3 player, or iPod. Podcasting also offers particular promise for non-native English speakers. This article describes how podcasting was used to offer academic support to students in a medical-surgical nursing course and to report the postimplementation test grade improvement among English as a second language nursing students. This article also discusses tips for implementing podcasting within the educational arena. Developing innovative ways to improve student retention is an ongoing process.

Currently, the diagnosis of burn depth is primarily based on a visual assessment and can be dependent on the surgeons' experience. The goal of this study was to determine the ability of laser Doppler flowmeter combined with a tissue spectrophotometer to discriminate burn depth in a miniature swine burn model. Burn injuries of varying depth, including superficial-partial, deep-partial, and full thickness, were created in seven Göttingen minipigs using an aluminium bar (100 °C), which was applied to the abdominal skin for periods of 1, 3, 6, 12, 30, and 60 seconds with gravity alone. The depth of injury was evaluated histologically using hematoxylin and eosin staining. All burns were assessed 3 hours after injury using a device that combines a laser light and a white light to determine blood flow, hemoglobin oxygenation, and relative amount of hemoglobin. The blood flow (41 vs. 124 arbitrary units [AU]) and relative amount of hemoglobin (32 vs. 52 AU) were significantly lower in full thickness compared with superficial-partial thickness burns. However, no significant differences in hemoglobin oxygenation were observed between these depths of burns (61 vs. 60%). These results show the ability of laser Doppler flowmeter and tissue spectrophotometer in combination to discriminate between various depths of injury in the minipig model, suggesting that this device may offer a valuable tool for burn depth assessment influencing burn management. © 2014 by the Wound Healing Society.

Mapping water table depth using geophysical and environmental variables.

PubMed

Buchanan, S; Triantafilis, J

2009-01-01

Despite its importance, accurate representation of the spatial distribution of water table depth remains one of the greatest deficiencies in many hydrological investigations. Historically, both inverse distance weighting (IDW) and ordinary kriging (OK) have been used to interpolate depths. These methods, however, have major limitations: namely they require large numbers of measurements to represent the spatial variability of water table depth and they do not represent the variation between measurement points. We address this issue by assessing the benefits of using stepwise multiple linear regression (MLR) with three different ancillary data sets to predict the water table depth at 100-m intervals. The ancillary data sets used are Electromagnetic (EM34 and EM38), gamma radiometric: potassium (K), uranium (eU), thorium (eTh), total count (TC), and morphometric data. Results show that MLR offers significant precision and accuracy benefits over OK and IDW. Inclusion of the morphometric data set yielded the greatest (16%) improvement in prediction accuracy compared with IDW, followed by the electromagnetic data set (5%). Use of the gamma radiometric data set showed no improvement. The greatest improvement, however, resulted when all data sets were combined (37% increase in prediction accuracy over IDW). Significantly, however, the use of MLR also allows for prediction in variations in water table depth between measurement points, which is crucial for land management.

Evaluating motion parallax and stereopsis as depth cues for autostereoscopic displays

NASA Astrophysics Data System (ADS)

Braun, Marius; Leiner, Ulrich; Ruschin, Detlef

2011-03-01

The perception of space in the real world is based on multifaceted depth cues, most of them monocular, some binocular. Developing 3D-displays raises the question, which of these depth cues are predominant and should be simulated by computational means in such a panel. Beyond the cues based on image content, such as shadows or patterns, Stereopsis and depth from motion parallax are the most significant mechanisms supporting observers with depth information. We set up a carefully designed test situation, widely excluding undesired other distance hints. Thereafter we conducted a user test to find out, which of these two depth cues is more relevant and whether a combination of both would increase accuracy in a depth estimation task. The trials were conducting utilizing our autostereoscopic "Free2C"-displays, which are capable to detect the user eye position and steer the image lobes dynamically into that direction. At the same time, eye position was used to update the virtual camera's location and thereby offering motion parallax to the observer. As far as we know, this was the first time that such a test has been conducted using an autosteresocopic display without any assistive technologies. Our results showed, in accordance with prior experiments, that both cues are effective, however Stereopsis is by order of magnitude more relevant. Combining both cues improved the precision of distance estimation by another 30-40%.

Mesophotic depths as refuge areas for fishery-targeted species on coral reefs

NASA Astrophysics Data System (ADS)

Lindfield, Steven J.; Harvey, Euan S.; Halford, Andrew R.; McIlwain, Jennifer L.

2016-03-01

Coral reefs are subjected to unprecedented levels of disturbance with population growth and climate change combining to reduce standing coral cover and stocks of reef fishes. Most of the damage is concentrated in shallow waters (<30 m deep) where humans can comfortably operate and where physical disturbances are most disruptive to marine organisms. Yet coral reefs can extend to depths exceeding 100 m, potentially offering refuge from the threats facing shallower reefs. We deployed baited remote underwater stereo-video systems (stereo-BRUVs) at depths of 10-90 m around the southern Mariana Islands to investigate whether fish species targeted by fishing in the shallows may be accruing benefits from being at depth. We show that biomass, abundance and species richness of fishery-targeted species increased from shallow reef areas to a depth of 60 m, whereas at greater depths, a lack of live coral habitat corresponded to lower numbers of fish. The majority of targeted species were found to have distributions that ranged from shallow depths (10 m) to depths of at least 70 m, emphasising that habitat, not depth, is the limiting factor in their vertical distribution. While the gradient of abundance and biomass versus depth was steepest for predatory species, the first species usually targeted by fishing, we also found that fishery-targeted herbivores prevailed in similar biomass and species richness to 60 m. Compared to shallow marine protected areas, there was clearly greater biomass of fishery-targeted species accrued in mesophotic depths. Particularly some species typically harvested by depth-limited fishing methods (e.g., spearfishing), such as the endangered humphead wrasse Cheilinus undulatus, were found in greater abundance on deeper reefs. We conclude that mesophotic depths provide essential fish habitat and refuge for fishery-targeted species, representing crucial zones for fishery management and research into the resilience of disturbed coral reef ecosystems.

The ethical tightrope: politics of intimacy and consensual method in sexuality research.

PubMed

Zago, Luiz F; Holmes, Dave

2015-06-01

This paper seeks to analyze the construction of ethics in sexuality research in which qualitative methods are employed in the field of social sciences. Analyses are based on a bibliographic review of current discussions on research methods of queer theory and on the authors' own experiences of past research on sexuality. The article offers a theoretical perspective on the ways ethnography and in-depth interviews become methods that can rely on a consensual method and create a politics of intimacy between the researchers and research participants. The politics of intimacy may contribute to the production of a politically engaged knowledge while escaping from the moral matrix that usually governs the relationship between researchers and research participants. It is argued here that the researcher's sexed and gendered body matters for fieldwork; that the consensual method among participants may be employed in sexuality research as a fruitful tool; and that the relationships created among researchers and participants can pose a challenge to predetermined ethical guidelines in research. As a result, discussions problematize the existence of a politics of intimacy in sexuality research that is characterized by ethical relations among research participants. © 2014 John Wiley & Sons Ltd.

Challenges and dilemmas: fieldwork with upland minorities in socialist Vietnam, Laos and southwest China.

PubMed

Turner, Sarah

2010-01-01

The Chinese, Vietnamese and Lao spaces within the upland Southeast Asian massif, sheltering over 80 million people belonging to geographically dispersed and politically fragmented minority populations, have only recently reopened to overseas academic endeavours. Undertaking social sciences research there among ethnic minority groups is underscored by a specific set of challenges, dilemmas, and negotiations. This special issue brings together Western academics and post-fieldwork doctoral students from the realms of social anthropology and human geography, who have conducted in-depth fieldwork among ethnic minorities in upland southwest China, northern Vietnam, and southern Laos. The articles provide insights into the struggles and constraints they faced in the field, set against an understanding of the historical context of field research in these locales. In this unique context that nowadays interweaves economic liberalisation with centralised and authoritarian political structures, the authors explore how they have negotiated and manoeuvred access to ethnic minority voices in complex cultural configurations. The ethical challenges raised and methodological reflections offered will be insightful for others conducting fieldwork in the socialist margins of the Southeast Asian massif and beyond. This specific context is introduced here, followed by a critique of the literature on the core themes that contributors raise.

Breast cancer diagnosis: biographical disruption, emotional experiences and strategic management in Thai women with breast cancer.

PubMed

Liamputtong, Pranee; Suwankhong, Dusanee

2015-09-01

In this article we draw on Bury's theory of biographical disruption to discuss the meanings of, and emotional experiences related to, being diagnosed with breast cancer among southern Thai women. Qualitative methods, including in-depth interviewing and drawing methods, were used to collect data from 20 women with breast cancer. The women perceived breast cancer to be a rhok raai; an evil or dread disease. They believed that breast cancer would lead to death. The disruption in their biography occurred when they detected abnormalities indicating breast cancer. The women's narratives revealed their chaotic lives upon this diagnosis and the news precipitated in them shock, fear, anxiety and loss of hope. Although they experienced chaos and disruption, the women cultivated strategies that helped them cope with their experiences by accepting their fate and adhering to Buddhist beliefs and practices. Through their narratives of biographical disruption, the women in our study offer healthcare providers knowledge that could lead to an appreciation of their needs and concerns. This knowledge is crucial for health professionals who wish to provide emotional support to women who have been diagnosed with breast cancer in Thailand and elsewhere. © 2015 Foundation for the Sociology of Health & Illness.

This article addresses the rare event of the hostage situation in a forensic psychiatric nursing setting. It has a specific focus on the initial response and the accompanying issues for nurses at the clinical interface as the situation emerges. The intention of this article is to both offer guidance and raise the profile of this unique management issue because little attention is drawn to early-stage hostage situations at an organizational level. When a hostage situation occurs, inadequate preparation can mean the difference between life and death for the hostage, negotiator, or hostage taker. This article provides an overview of the relevant literature and offers guidance about the actions required when a nurse suddenly becomes responsible for managing the early stages of such a traumatic event. Responses, safety, and communication factors concerning the hostage taker are covered.

Language Model Applications to Spelling with Brain-Computer Interfaces

PubMed Central

Mora-Cortes, Anderson; Manyakov, Nikolay V.; Chumerin, Nikolay; Van Hulle, Marc M.

2014-01-01

Within the Ambient Assisted Living (AAL) community, Brain-Computer Interfaces (BCIs) have raised great hopes as they provide alternative communication means for persons with disabilities bypassing the need for speech and other motor activities. Although significant advancements have been realized in the last decade, applications of language models (e.g., word prediction, completion) have only recently started to appear in BCI systems. The main goal of this article is to review the language model applications that supplement non-invasive BCI-based communication systems by discussing their potential and limitations, and to discern future trends. First, a brief overview of the most prominent BCI spelling systems is given, followed by an in-depth discussion of the language models applied to them. These language models are classified according to their functionality in the context of BCI-based spelling: the static/dynamic nature of the user interface, the use of error correction and predictive spelling, and the potential to improve their classification performance by using language models. To conclude, the review offers an overview of the advantages and challenges when implementing language models in BCI-based communication systems when implemented in conjunction with other AAL technologies.

Siegel, Deborah H

2013-01-01

Unlike in the past, most adoption agencies today offer birth parents and adoptive parents the opportunity to share identifying information and have contact with each other. To understand the impacts of different open adoption arrangements, a qualitative descriptive study using a snowball sample of 44 adoptive parents throughout New England began in 1988. Every seven years these parents who adopted infants in open adoptions have participated in tape-recorded interviews to explore their evolving reactions to their open adoption experiences. This article reports the results of in-depth interviews with these parents now that their children have reached young adulthood. This longitudinal research illuminates how open adoptions change over the course of childhood and adolescence, parents' feelings about open adoption, challenges that emerge in their relationships with their children's birth families, how those challenges are managed and viewed, and parents' advice for others living with open adoption and for clinical social work practice and policy. Findings reveal that regardless of the type of openness, these adoptive parents generally feel positive about knowing the birth parents and having contact with them, are comfortable with open adoption, and see it serving the child's best interests.

Navigating the gender minefield: An IPV prevention campaign sheds light on the gender gap.

PubMed

Keller, Sarah N; Honea, Joy C

2016-01-01

This article examines how differences in male and female views about intimate partner violence (IPV) contributed to divergent responses to a prevention campaign conducted in the western USA. The study examines focus groups (n = 22) and in-depth interview data (n = 13) collected during campaign development to shed light on quantitative results indicating that women (but not men) increased their perceived severity of domestic violence and awareness of services from pre-test to post-test, while male attitudes moved in the opposite direction. Results of the qualitative study provide the basis for the authors' conclusions about why reactions differed: (1) men's unwillingness to view abuse within a gender context limits men's ability to accept the inequity in statistically demonstrated male and female roles as perpetrators and victims; (2) male resentment of existing gender stereotypes contributed to a rejection of campaign messages that utilised gender prevalence statistics to depict images showing men as perpetrators and women as victims; and (3) victim blaming attitudes contributed to resistance to empathy for victims depicted in the campaign. The authors offer suggestions for future campaigns that foster agency among both perpetrators and survivors while confronting the structural barriers to enacting change.

Nanocarrier for poorly water-soluble anticancer drugs--barriers of translation and solutions.

PubMed

Narvekar, Mayuri; Xue, Hui Yi; Eoh, June Young; Wong, Ho Lun

2014-08-01

Many existing chemotherapeutic drugs, repurposed drugs and newly developed small-molecule anticancer compounds have high lipophilicity and low water-solubility. Currently, these poorly water-soluble anticancer drugs (PWSAD) are generally solubilized using high concentrations of surfactants and co-solvents, which frequently lead to adverse side effects. In recent years, researchers have been actively exploring the use of nanotechnology as an alternative to the solvent-based drug solubilization approach. Several classes of nanocarrier systems (lipid-based, polymer-based and albumin-based) are widely studied for encapsulation and delivery of the existing and new PWSAD. These nanocarriers were also shown to offer several additional advantages such as enhanced tumour accumulation, reduced systemic toxicity and improved therapeutic effectiveness. In this article, the recent nanotechnological advances in PWSAD delivery will be reviewed. The barriers commonly encountered in the development of PWSAD nanoformulations (e.g. formulation issues and nanotoxicity issues) and the strategies to overcome these barriers will also be discussed. It is our goal to provide the pharmaceutical scientists and clinicians with more in-depth information about the nanodelivery approach, thus, more efficacious and safe PWSAD nanoformulations can be developed with improved translational success.

Using Count Data and Ordered Models in National Forest Recreation Demand Analysis

NASA Astrophysics Data System (ADS)

Simões, Paula; Barata, Eduardo; Cruz, Luis

2013-11-01

This research addresses the need to improve our knowledge on the demand for national forests for recreation and offers an in-depth data analysis supported by the complementary use of count data and ordered models. From a policy-making perspective, while count data models enable the estimation of monetary welfare measures, ordered models allow for the wider use of the database and provide a more flexible analysis of data. The main purpose of this article is to analyse the individual forest recreation demand and to derive a measure of its current use value. To allow a more complete analysis of the forest recreation demand structure the econometric approach supplements the use of count data models with ordered category models using data obtained by means of an on-site survey in the Bussaco National Forest (Portugal). Overall, both models reveal that travel cost and substitute prices are important explanatory variables, visits are a normal good and demographic variables seem to have no influence on demand. In particular, estimated price and income elasticities of demand are quite low. Accordingly, it is possible to argue that travel cost (price) in isolation may be expected to have a low impact on visitation levels.

The purpose of this pilot study was to design, implement, and evaluate a Family Empowerment Program (FEP), guided by the Illness Beliefs Model. Participants included 25 Thai family members who were the primary caregivers of a child with thalassemia. In Phase I, data were collected from participants using individual in-depth interviews and focus groups before involvement in the FEP. In Phase II, 12 hr of FEP sessions were offered to groups of participants. Content analysis of the audiotaped FEP sessions is reported in this article. Family caregivers reported that the FEP helped them share beliefs and experiences related to caring for their child with thalassemia, make decisions related to families' problems/needs and beliefs, provide each other mutual social support, and develop increased ability to manage care for their chronically ill child through sharing information and learning from other family caregivers about family functioning, family management, and family relationships. Future research is needed to examine the FEP intervention under more controlled conditions with measures that include family functioning and child health outcomes. © The Author(s) 2015.

Evaluating the potential for remote bathymetric mapping of a turbid, sand-bed river: 1. Field spectroscopy and radiative transfer modeling

USGS Publications Warehouse

Legleiter, C.J.; Kinzel, P.J.; Overstreet, B.T.

2011-01-01

Remote sensing offers an efficient means of mapping bathymetry in river systems, but this approach has been applied primarily to clear-flowing, gravel bed streams. This study used field spectroscopy and radiative transfer modeling to assess the feasibility of spectrally based depth retrieval in a sand-bed river with a higher suspended sediment concentration (SSC) and greater water turbidity. Attenuation of light within the water column was characterized by measuring the amount of downwelling radiant energy at different depths and calculating a diffuse attenuation coefficient, Kd. Attenuation was strongest in blue and near-infrared bands due to scattering by suspended sediment and absorption by water, respectively. Even for red wavelengths with the lowest values of Kd, only a small fraction of the incident light propagated to the bed, restricting the range of depths amenable to remote sensing. Spectra recorded above the water surface were used to establish a strong, linear relationship (R2 = 0.949) between flow depth and a simple band ratio; even under moderately turbid conditions, depth remained the primary control on reflectance. Constraints on depth retrieval were examined via numerical modeling of radiative transfer within the atmosphere and water column. SSC and sensor radiometric resolution limited both the maximum detectable depth and the precision of image-derived depth estimates. Thus, although field spectra indicated that the bathymetry of turbid channels could be remotely mapped, model results implied that depth retrieval in sediment-laden rivers would be limited to shallow depths (on the order of 0.5 m) and subject to a significant degree of uncertainty. ?? 2011 by the American Geophysical Union.

de Moura, Joaquim; Novo, Jorge; Charlón, Pablo; Barreira, Noelia; Ortega, Marcos

2017-12-01

Retinal vessel tree extraction is a crucial step for analyzing the microcirculation, a frequently needed process in the study of relevant diseases. To date, this has normally been done by using 2D image capture paradigms, offering a restricted visualization of the real layout of the retinal vasculature. In this work, we propose a new approach that automatically segments and reconstructs the 3D retinal vessel tree by combining near-infrared reflectance retinography information with Optical Coherence Tomography (OCT) sections. Our proposal identifies the vessels, estimates their calibers, and obtains the depth at all the positions of the entire vessel tree, thereby enabling the reconstruction of the 3D layout of the complete arteriovenous tree for subsequent analysis. The method was tested using 991 OCT images combined with their corresponding near-infrared reflectance retinography. The different stages of the methodology were validated using the opinion of an expert as a reference. The tests offered accurate results, showing coherent reconstructions of the 3D vasculature that can be analyzed in the diagnosis of relevant diseases affecting the retinal microcirculation, such as hypertension or diabetes, among others.

Wave height estimates from pressure and velocity data at an intermediate depth in the presence of uniform currents

NASA Astrophysics Data System (ADS)

Basu, Biswajit

2017-12-01

Bounds on estimates of wave heights (valid for large amplitudes) from pressure and flow measurements at an arbitrary intermediate depth have been provided. Two-dimensional irrotational steady water waves over a flat bed with a finite depth in the presence of underlying uniform currents have been considered in the analysis. Five different upper bounds based on a combination of pressure and velocity field measurements have been derived, though there is only one available lower bound on the wave height in the case of the speed of current greater than or less than the wave speed. This article is part of the theme issue 'Nonlinear water waves'.

'Between Combat boots and Birkenstocks'-Lessons from HIV/AIDS, SARS, H1N1 and Ebola.

PubMed

Crawford, R; Rutz, D C; Evans, D P

2016-12-01

In late 2013, an Ebola outbreak quickly grew into an epidemic of extraordinary magnitude, killing more people than all previous Ebola outbreaks combined. Although the epidemic was unprecedented, the world had previously experienced several acute public health emergencies requiring global coordination. HIV/AIDS, SARS and H1N1 tested global response, and in each case coordination proved problematic, making the 2013-2015 Ebola epidemic no exception. The purpose of this project was to identify persistent vulnerabilities within global public health emergency response and to identify areas for future research and improvement. Non-systematic review and qualitative interview study. Using PubMed and Google, a comprehensive search of articles connected to the HIV/AIDS, SARS, H1N1 and Ebola responses was conducted. Then, 21 key responders involved in those emergencies, primarily from the US Centers for Disease Control and Prevention, participated in in-depth interviews. The content analysis and in-depth interview data were analysed using MAXQDA analysis software. A number of issues emerged, including cultural and political clashes within relevant agencies and a lack of confidence in those agencies, policy barriers that hinder long-term international response, a shortage of personnel and resources, itemized funding streams that limit flexibility to direct resources, and challenges to deploying responders internationally. The data suggest that the world remains ill prepared to handle sustained responses and global pandemics. The study identified major vulnerabilities persistent within US-led global public health response and offers recommendations for further focused research to fully understand why these challenges persist.

Climate, environmental and socio-economic change: weighing up the balance in vector-borne disease transmission

2015-02-16

Arguably one of the most important effects of climate change is the potential impact on human health. While this is likely to take many forms, the implications for future transmission of vector-borne diseases (VBDs), given their ongoing contribution to global disease burden, are both extremely important and highly uncertain. In part, this is due not only to data limitations and methodological challenges when integrating climate-driven VBD models and climate change projections, but, perhaps most crucially, the multitude of epidemiological, ecological, and socioeconomic factors that drive VBD transmission, and this complexity has generated considerable debate over the last 10-15 years. Inmore » this article, and Theme Issue, we seek to elucidate current knowledge around this topic, identify key themes and uncertainties, evaluate ongoing challenges and open research questions, and, crucially, offer some solutions for the field moving forwards. Although many of these challenges are ubiquitous across multiple VBDs, more specific issues also arise in different vector-pathogen systems. This Theme Issue seeks to cover both, reflected in the breadth and depth of the topics and VBD-systems considered, itself strongly indicative of the challenging, but necessary, multidisciplinary nature of this research field.« less

The daily digital practice as a form of self-care: Using photography for everyday well-being.

Brewster, Liz; Cox, Andrew M

2018-04-01

Interest in the connection between involvement in digital communities and well-being has increased as these communities become more commonplace. Specific models of interaction that affect well-being have emerged; here, we examine one of those models, termed 'digital daily practice'. Digital daily practices involve a commitment to doing one thing - exercise, photography and writing - every day and sharing it online. Participants in these practices agree that they provide an unexpected benefit of improving well-being. This article makes an in-depth examination of one digital daily practice, photo-a-day, using a practice theory framework to understand the affordances it offers for well-being. We engage with the literature on well-being and self-care, critiquing its presentation of well-being as an individual trait. We present data from an ethnographic study including interviews and observations to highlight how photo-a-day as a practice functions as self-care and how communities are formed around it. Photo-a-day is not a simple and uncomplicated practice; rather it is the complex affordances and variance within the practice that relate it to well-being. We conclude that this practice has multi-faceted benefits for improving well-being.

Learning science is an emerging interdisciplinary field that offers educators key insights about what happens in the brain when learning occurs. In addition to explanations about the learning process, which includes memory and involves different parts of the brain, learning science offers effective strategies to inform the planning and implementation of activities and programs in continuing education and continuing professional development. This article provides a brief description of learning, including the three key steps of encoding, consolidation and retrieval. The article also introduces four major learning-science strategies, known as distributed learning, retrieval practice, interleaving, and elaboration, which share the importance of considerable practice. Finally, the article describes how learning science aligns with the general findings from the most recent synthesis of systematic reviews about the effectiveness of continuing medical education.

Towards a political ontology of state power: a comment on Colin Hay's article.

2014-09-01

This article offers some critical realist, strategic-relational comments on Colin Hay's proposal to treat the state as an 'as-if-real' concept. The critique first develops an alternative account of ontology, which is more suited to analyses of the state and state power; it then distinguishes the 'intransitive' properties of the real world as an object of investigation from the 'transitive' features of its scientific investigation and thereby provides a clearer understanding of what is at stake in 'as-if-realism'; and it ends with the suggestion that a concern with the modalities of state power rather than with the state per se offers a more fruitful approach to the genuine issues raised in Hay's article and in his earlier strategic-relational contributions to political analysis. © London School of Economics and Political Science 2014.

Telecentric 3D profilometry based on phase-shifting fringe projection.

PubMed

Li, Dong; Liu, Chunyang; Tian, Jindong

2014-12-29

Three dimensional shape measurement in the microscopic range becomes increasingly important with the development of micro manufacturing technology. Microscopic fringe projection techniques offer a fast, robust, and full-field measurement for field sizes from approximately 1 mm² to several cm². However, the depth of field is very small due to the imaging of non-telecentric microscope, which is often not sufficient to measure the complete depth of a 3D-object. And the calibration of phase-to-depth conversion is complicated which need a precision translation stage and a reference plane. In this paper, we propose a novel telecentric phase-shifting projected fringe profilometry for small and thick objects. Telecentric imaging extends the depth of field approximately to millimeter order, which is much larger than that of microscopy. To avoid the complicated phase-to-depth conversion in microscopic fringe projection, we develop a new system calibration method of camera and projector based on telecentric imaging model. Based on these, a 3D reconstruction of telecentric imaging is presented with stereovision aided by fringe phase maps. Experiments demonstrated the feasibility and high measurement accuracy of the proposed system for thick object.

"I experienced freedom within the frame of my own narrative": The contribution of psychodrama techniques to experiential learning in teacher training

NASA Astrophysics Data System (ADS)

ter Avest, Ina

2017-02-01

To prepare Dutch students in education for critical situations in their professional life as a teacher, part of their training is to ask them to reflect upon their own experiences in their life as a child, a pupil and a student - experiences of crucial moments or with significant others which are still of the utmost importance to them. This article underlines the significance of so-called "experiential learning" in student career counselling. In this context, experiential learning is understood as an extension of in- depth reflection on critical incidents and critical persons in the biography of pre-service teachers. This reflection - customary and effective in Dutch teacher training - is a verbal process. However, this technique does not seem to be adequate for many students from other cultural backgrounds (e.g. second-generation descendants of migrant workers). By consequence, some of these students are not able to take newly offered information on board, but remain imprisoned in their own culture-related narrative, their own ethnic society of mind. Research has shown that for these students, psychodrama techniques, focusing on non-verbal and playful aspects of reflection, seem to be more suitable. The author of this article presents a sample case from a pilot study which used one of the psychodrama techniques called the empty chair. The findings of the pilot study are promising in the sense that experiencing different I- positions does seem to help students from other cultural backgrounds to develop agency in responding to hitherto unfamiliar and confusing situations.

Controlling Force and Depth in Friction Stir Welding

NASA Technical Reports Server (NTRS)

Adams, Glynn; Loftus, Zachary; McCormac, Nathan; Venable, Richard

2005-01-01

Feedback control of the penetration force applied to a pin tool in friction stir welding has been found to be a robust and reliable means for controlling the depth of penetration of the tool. This discovery has made it possible to simplify depth control and to weld with greater repeatability, even on workpieces with long weld joints. Prior to this discovery, depths of penetration in friction stir welding were controlled by hard-tooled roller assemblies or by depth actuators controlled by feedback from such external sensors as linear variable-differential transformers or laser-based devices. These means of control are limited: A hard-tooled roller assembly confines a pin tool to a preset depth that cannot be changed easily during the welding process. A measurement by an external sensor is only an indirect indicative of the depth of penetration, and computations to correlate such a measurement with a depth of penetration are vulnerable to error. The present force-feedback approach exploits the proportionality between the depth and the force of penetration Unlike a depth measurement taken by an external sensor, a force measurement can be direct because it can be taken by a sensor coupled directly to the pin tool. The reading can be processed through a modern electronic servo control system to control an actuator to keep the applied penetration force at the desired level. In comparison with the older depth-control methods described above, this method offers greater sensitivity to plasticizing of the workpiece metal and is less sensitive to process noise, resulting in a more consistent process. In an experiment, a tapered panel was friction stir welded while controlling the force of penetration according to this method. The figure is a plot of measurements taken during the experiment, showing that force was controlled with a variation of 200 lb (890 N), resulting in control of the depth of penetration with a variation of 0.004 in. (0.1 mm).

Message frames interact with motivational systems to determine depth of message processing.

PubMed

Shen, Lijiang; Dillard, James Price

2009-09-01

Although several theoretical perspectives predict that negatively framed messages will be processed more deeply than positively framed messages, a recent meta-analysis found no such difference. In this article, the authors explore 2 explanations for this inconsistency. One possibility is methodological: the statistics used in the primary studies underestimated framing effects on depth of message processing because the data were maldistributed. The other is theoretical: the absence of a main effect is veridical, but framing interacts with individual differences that predispose individuals to greater or lesser depth of processing. Data from 2 experiments (Ns = 286 and 252) were analyzed via tobit regression, a technique designed to overcome the limitations of maldistributed data. One study showed the predicted main effect for framing, but the other did not. Both studies showed the anticipated interaction: Depth of processing correlated positively with a measure of the behavioral activation system in the advantage framing condition, whereas depth of processing correlated positively with the behavioral inhibition system in the disadvantage framing condition.

Existence and amplitude bounds for irrotational water waves in finite depth

NASA Astrophysics Data System (ADS)

Kogelbauer, Florian

2017-12-01

We prove the existence of solutions to the irrotational water-wave problem in finite depth and derive an explicit upper bound on the amplitude of the nonlinear solutions in terms of the wavenumber, the total hydraulic head, the wave speed and the relative mass flux. Our approach relies upon a reformulation of the water-wave problem as a one-dimensional pseudo-differential equation and the Newton-Kantorovich iteration for Banach spaces. This article is part of the theme issue 'Nonlinear water waves'.

2014-01-01

E-learning is a popular method of continuous medical education (CME) which is becoming increasingly available to doctors. A specific form of E-learning is an online knowledge test accompanying a journal article. CME accreditation points can be obtained by reading an article and then answering test questions on it. This is a user-friendly form of CME which an increasing number of journals are offering as a service to their readers. The Dutch Journal of Medicine (NTvG) has been offering accredited tests to its readers since 2011. On comparison with international journals, a high standard has been set by the development of a test concept in which interpretation and reflection play integral roles. In the Dutch setting, the concept of the test was developed by professional bodies working closely together and it is a concept that is used as an example to other journals.

Ethics, big data and computing in epidemiology and public health.

PubMed

Salerno, Jennifer; Knoppers, Bartha M; Lee, Lisa M; Hlaing, WayWay M; Goodman, Kenneth W

2017-05-01

This article reflects on the activities of the Ethics Committee of the American College of Epidemiology (ACE). Members of the Ethics Committee identified an opportunity to elaborate on knowledge gained since the inception of the original Ethics Guidelines published by the ACE Ethics and Standards of Practice Committee in 2000. The ACE Ethics Committee presented a symposium session at the 2016 Epidemiology Congress of the Americas in Miami on the evolving complexities of ethics and epidemiology as it pertains to "big data." This article presents a summary and further discussion of that symposium session. Three topic areas were presented: the policy implications of big data and computing, the fallacy of "secondary" data sources, and the duty of citizens to contribute to big data. A balanced perspective is needed that provides safeguards for individuals but also furthers research to improve population health. Our in-depth review offers next steps for teaching of ethics and epidemiology, as well as for epidemiological research, public health practice, and health policy. To address contemporary topics in the area of ethics and epidemiology, the Ethics Committee hosted a symposium session on the timely topic of big data. Technological advancements in clinical medicine and genetic epidemiology research coupled with rapid advancements in data networks, storage, and computation at a lower cost are resulting in the growth of huge data repositories. Big data increases concerns about data integrity; informed consent; protection of individual privacy, confidentiality, and harm; data reidentification; and the reporting of faulty inferences.

Synoptic channel morphodynamics with topo-bathymetric airborne lidar: promises, pitfalls and research needs

NASA Astrophysics Data System (ADS)

Lague, D.; Launeau, P.; Gouraud, E.

2017-12-01

Topo-bathymetric airborne lidar sensors using a green laser penetrating water and suitable for hydrography are now sold by major manufacturers. In the context of channel morphodynamics, repeat surveys could offer synoptic high resolution measurement of topo-bathymetric change, a key data that is currently missing. Yet, beyond the technological promise, what can we really achieve with these sensors in terms of depth penetration and bathymetric accuracy ? Can all rivers be surveyed ? How easy it is to process this new type of data to get the data needed by geomorphologists ? Here we report on the use of the Optech Titan dual wavelength (1064 nm & 532 nm) operated by the universities of Rennes and Nantes (France) and deployed over several rivers and lakes in France, including repeat surveys. We will illustrate cases where the topo-bathymetric survey is complete, reaching up to 6 m in rivers and offers unprecedented data for channel morphology analysis over tens of kilometres. We will also present challenging cases for which the technology will never work, or for which new algorithms to process full waveform are required. We will illustrate new developments for automated processing of large datasets, including the critical step of water surface detection and refraction correction. In suitable rivers, airborne topo-bathymetric surveys offer unprecedented synoptic 3D data at very high resolution (> 15 pts/m² in bathy) and precision (better than 10 cm for the bathy) down to 5-6 meters depth, with a perfectly continuous topography to bathymetry transition. This presentation will illustrate how this new type of data, when combined with 2D hydraulics modelling offers news insights into the spatial variations of friction in relation to channel bedforms, and the connectivity between rivers and floodplains.

Etch depth mapping of phase binary computer-generated holograms by means of specular spectroscopic scatterometry

NASA Astrophysics Data System (ADS)

Korolkov, Victor P.; Konchenko, Alexander S.; Cherkashin, Vadim V.; Mironnikov, Nikolay G.; Poleshchuk, Alexander G.

2013-09-01

Detailed analysis of etch depth map for phase binary computer-generated holograms intended for testing aspheric optics is a very important task. In particular, diffractive Fizeau null lenses need to be carefully tested for uniformity of etch depth. We offer a simplified version of the specular spectroscopic scatterometry method. It is based on the spectral properties of binary phase multi-order gratings. An intensity of zero order is a periodical function of illumination light wave number. The grating grooves depth can be calculated as it is inversely proportional to the period. Measurement in reflection allows one to increase the phase depth of the grooves by a factor of 2 and measure more precisely shallow phase gratings. Measurement uncertainty is mainly defined by the following parameters: shifts of the spectrum maximums that occur due to the tilted grooves sidewalls, uncertainty of light incidence angle measurement, and spectrophotometer wavelength error. It is theoretically and experimentally shown that the method we describe can ensure 1% error. However, fiber spectrometers are more convenient for scanning measurements of large area computer-generated holograms. Our experimental system for characterization of binary computer-generated holograms was developed using a fiber spectrometer.

[Eye development in children. Part I. Eyeball dimensions].

PubMed

Lachowicz, Ewelina; Czepita, Damian

2010-01-01

The aim of an article is to introduce and elaborate on the available literature concerning eyeball development. The information content in the article comes from studies performed on groups of children of different ages. In some analysis study groups were chosen depending on sex. Axial length of the eye, depth of anterior chamber, lens's thickness and vitreous's dimension was defined. Intensive changes of eyeball dimensions progress with age. A period of fast and slow growth of the eye can be discerned. Axial length of the eye, depth of anterior chamber, lens's thickness and vitreous's dimension increase over time. Growth of the axial length is mainly caused by increasing axial length of vitreous cavity. The increase in depth of the anterior chamber plays a lesser role. Girls tend to have shorter eyes compared with boys. Both age and male gender are associated with deeper anterior chambers and larger vitreous cavity. Lens thickness decreases with the growth of the eyeball. However gender does not play a role. Based on current literature, it is difficult exactly indicate what are the standards of eyeball growth in children and youths. To establish these parameters, further studies on the another examination in representative group of children and teenagers are necessary.

Molecular imaging is very promising technique used for surgical guidance, which requires advancements related to properties of imaging agents and subsequent data retrieval methods from measured multispectral images. In this article, an upconversion material is introduced for subsurface near-infrared imaging and for the depth recovery of the material embedded below the biological tissue. The results confirm significant correlation between the analytical depth estimate of the material under the tissue and the measured ratio of emitted light from the material at two different wavelengths. Experiments with biological tissue samples demonstrate depth resolved imaging using the rare earth doped multifunctional phosphors. In vitro tests reveal no significant toxicity, whereas the magnetic measurements of the phosphors show that the particles are suitable as magnetic resonance imaging agents. The confocal imaging of fibroblast cells with these phosphors reveals their potential for in vivo imaging. The depth-resolved imaging technique with such phosphors has broad implications for real-time intraoperative surgical guidance. PMID:26322519

Advances in information technology now offer several options for child and adolescent psychopharmacologists to navigate the increasingly complex terrain of scientific literature and keep abreast of the rapidly changing advances in our field. MEDLINE, the world's largest database of medical literature, can be accessed and searched by a variety of free or fee-based services. In addition to efficient retrieval of citations and abstracts based on subject, author, or title, many of these services now provide, for a fee, the entire text and graphics of articles (displayed on computer screen, faxed, or mailed). There are also current awareness services to alert the user when new requested literature become available as well as services to send via e-mail the tables of contents of requested journals (sometimes prior to paper publication). For online citation and abstract retrieval, we found that free services, such as PubMed, performed as good or better than fee-based services. Physicians' Online, sponsored by the pharmaceutical industry, offered the lowest price for full-text manuscript delivery. In this article, we review literature search, delivery, and update services and offer some tips on how to most effectively use these resources.

Morzhukhina, Anastasia; Nikitin, Stanislav; Akimova, Elena

2018-03-01

Aggressive environments have a significant impact on destruction of many reinforced concrete structures, such as high-rise constructions or chemical plants. For example, some high-rise constructions are equipped with a swimming pool, so they are exposed to chloride ions in the air. Penetration of aggressive chemical substances into the body of concrete contributes to acceleration of reinforced concrete structure corrosion that in turn leads to load bearing capacity loss and destruction of the building. The article considers and analyzes the main technologies for calculating penetration depth of various aggressive substances into the body of concrete. The calculation of corrosion depth was made for 50-year service life.

Towards high performing hospital enterprise systems: an empirical and literature based design framework

NASA Astrophysics Data System (ADS)

dos Santos Fradinho, Jorge Miguel

2014-05-01

Our understanding of enterprise systems (ES) is gradually evolving towards a sense of design which leverages multidisciplinary bodies of knowledge that may bolster hybrid research designs and together further the characterisation of ES operation and performance. This article aims to contribute towards ES design theory with its hospital enterprise systems design (HESD) framework, which reflects a rich multidisciplinary literature and two in-depth hospital empirical cases from the US and UK. In doing so it leverages systems thinking principles and traditionally disparate bodies of knowledge to bolster the theoretical evolution and foundation of ES. A total of seven core ES design elements are identified and characterised with 24 main categories and 53 subcategories. In addition, it builds on recent work which suggests that hospital enterprises are comprised of multiple internal ES configurations which may generate different levels of performance. Multiple sources of evidence were collected including electronic medical records, 54 recorded interviews, observation, and internal documents. Both in-depth cases compare and contrast higher and lower performing ES configurations. Following literal replication across in-depth cases, this article concludes that hospital performance can be improved through an enriched understanding of hospital ES design.

A Case Study Documenting the Process by Which Biology Instructors Transition from Teacher-Centered to Learner-Centered Teaching.

PubMed

Marbach-Ad, Gili; Hunt Rietschel, Carly

2016-01-01

In this study, we used a case study approach to obtain an in-depth understanding of the change process of two university instructors who were involved with redesigning a biology course. Given the hesitancy of many biology instructors to adopt evidence-based, learner-centered teaching methods, there is a critical need to understand how biology instructors transition from teacher-centered (i.e., lecture-based) instruction to teaching that focuses on the students. Using the innovation-decision model for change, we explored the motivation, decision-making, and reflective processes of the two instructors through two consecutive, large-enrollment biology course offerings. Our data reveal that the change process is somewhat unpredictable, requiring patience and persistence during inevitable challenges that arise for instructors and students. For example, the change process requires instructors to adopt a teacher-facilitator role as opposed to an expert role, to cover fewer course topics in greater depth, and to give students a degree of control over their own learning. Students must adjust to taking responsibility for their own learning, working collaboratively, and relinquishing the anonymity afforded by lecture-based teaching. We suggest implications for instructors wishing to change their teaching and administrators wishing to encourage adoption of learner-centered teaching at their institutions. © 2016 G.

Ideal men: masculinity and decline in seventeenth-century Spain.

PubMed

Lehfeldt, Elizabeth A

2008-01-01

This article examines how the experience and critique of their country's decline led Spaniards to craft a distinct discourse of masculinity in the seventeenth century. As they self-consciously examined Spain's crisis and offered political and economic solutions, these same writers also offered a scathing critique of standards of masculinity. Using the figure of the ideal nobleman as a case study, the article examines how moralists, arbitristas, and hagiographers constructed a dynamic code of manhood linked to questions of productivity, male chastity, and military performance. Further, it argues that this discourse was ultimately nostalgic and failed to adapt itself to the circumstances of the seventeenth century.

What to do when trust has been breached in your practice.

PubMed

Hills, Laura

2013-01-01

We've all experienced gossiping, missed deadlines, someone taking credit for another's work, and little white lies. These and other breaches of trust are commonplace. However, they do more damage in the medical practice than many practice managers realize. This article argues that medical practice employees need to trust their managers, patients, doctors, one another, and even the security of their jobs so they are able to focus on their daily tasks and perform well. It defines trust as both a logical and emotional act and describes common breaches of workplace trust. It defines three characteristics of high-trust organizations and illustrates through examples how practice managers can demonstrate their trustworthiness through their actions, not only through their words. This article also offers seven steps for rebuilding trust that has been breached. It offers readers two instruments: a survey tool practice managers can use to assess the trust in their practices and a self-quiz practice managers can take to assess their own trustworthiness. Finally, this article offers research about the impact of trust on the bottom line and 10 truths about trust that medical practice managers can share with their employees.

Young people and health: towards a new conceptual framework for understanding empowerment.

PubMed

Spencer, Grace

2014-01-01

In recent times, empowerment has become the focus of much work with young people amidst increasing concerns about their health. Empowerment is often offered as a 'solution' to such concerns, with the uncritical assumption being made that empowerment unproblematically results in positive health outcomes. While much of the health promotion literature advocates 'empowerment', it often does so without offering a clear conceptualisation of the word itself or indeed addressing the thorny theoretical tensions surrounding the concept's root word of power. In light of this omission, this article offers a more theoretically informed conceptualisation of empowerment and considers the relationship to young people's health. This article outlines a more dynamic and generative conceptualisation of empowerment than hitherto articulated in the literature, informed by Lukes' multidimensional perspective of power. Drawing on findings from an ethnographic study on empowerment and young people's health, this article develops six conceptually distinct forms of empowerment (impositional, dispositional, concessional, oppositional, normative and transformative). Data were collected from 55 young men and women aged 15-16 years through group discussions, individual interviews and observational work in a school and surrounding community settings in England. Crucially, these six new forms of empowerment capture and synthesise individual, structural and ideological elements of power that differentially, and sometimes inconsistently, shape the possibilities for young people's empowerment. Of significance is the way in which these different forms of empowerment intersect to (re)produce relations of power and may offer different possibilities for health promotion.

Depth zonation and bathymetric trends of deep-sea megafaunal scavengers of the Hawaiian Islands

NASA Astrophysics Data System (ADS)

Yeh, John; Drazen, Jeffrey C.

2009-02-01

The deep sea has been shown to exhibit strong depth zonation in species composition and abundance. Examination of these patterns can offer ecological insight into how organisms adapt and respond to changing environmental parameters that co-occur with depth. Here we provide the first tropical study on bathymetric zonation and other depth-related trends (size, abundance, and species richness) spanning shelf to abyssal depths of scavenging megafauna. Baited time-lapse free-vehicle cameras were used to examine the deep-sea benthic and demersal scavenging communities of the Hawaiian Islands, an area for which the biology and ecology have remained poorly studied below 2000 m. Twenty-two deployments ranging in depth from 250 to 4783 m yielded 37 taxa attracted to bait, including the first known occurrence of the family Zoarcidae in the Hawaiian Islands. Cluster analysis of Bray-Curtis similarity of species peak abundance ( nmax) revealed four main faunal zones (250-500, 1000, 1500-3000, and ⩾4000 m) with significant separation (ANOSIM, global R=0.907, p=0.001) between designated depth groups. A major faunal break was identified at the 500-1000 m transition where species turnover was greatest, coinciding with the location of the local oxygen minimum zone. Dominance in species assemblage shifted from decapod crustaceans to teleosts moving from shallow to deeper faunal zones. Significant size differences in total length with depth were found for two of the four fish species examined. A logarithmic decline was observed in scavenger relative abundance with depth. Evidence of interaction between scavenging species was also noted between Synaphobranchus affinis and Neolithodes sp. (competition) and Histiobranchus sp. and aristeid shrimp (predation), suggesting that interactions between scavengers could influence indices of abundance generated from baited camera data.

Seafloor in the Expanded Malaysia Airlines Flight MH370 Search Area

NASA Astrophysics Data System (ADS)

Smith, W. H. F.; Marks, K. M.; Beaman, R. J.

2014-12-01

Smith and Marks (Eos Trans. AGU, 95(21), 27 May 2014) illustrated a map of the seafloor in the Malaysia Airlines Flight MH370 search area. This map showed a bathymetric model that is constructed from a combination of available ship soundings and depths estimated from satellite altimetry. They noted that available depth measurements covered only 5% of their study region, and that very few of these measurements were collected using modern multibeam and navigation systems. Recently the MH370 search has been expanded along the "7th Arc" to encompass newly prioritized underwater search areas identified in an Australian Transport Safety Bureau report (AE-2014-054, 26 June 2014). While the new "Priority" search area is within the Eos article Fig. 1, the new "Wide" search area extends beyond the region evaluated in Eos. Additionally, multibeam data that were not incorporated in the bathymetric model have been made available to us after the Eos article was published. This presentation will update and extend the study published in Eos. We will present illustrations of the expanded region, sounding coverage, and tectonic features that are associated with steep topographic slopes. Our results include comparisons of multibeam survey depths and bathymetric model depths. The standard deviation of the differences is 182 m, with the greatest differences (exceeding 1000 m) over steep topographic slopes, and the smallest over low-relief ocean floor. This is consistent with differences found by Smith and Sandwell (JGR, 99(B11), 1994) between soundings and bathymetric predictions from altimetry. Such depth differences are common where bathymetric model constraints are sparse, which is typical of many of the world's oceans.

Introduction to the JPA special issue: Can the Psychodynamic Diagnostic Manual put the complex person back at the center-stage of personality assessment?

PubMed

Huprich, Steven K; Meyer, Gregory J

2011-03-01

We briefly introduce this special issue, which focuses both on the Psychodynamic Diagnostic Manual (PDM) and the practice of idiographic, depth-oriented personality assessment. The 7 articles in this issue are diverse in scope but all address these 2 important topics. To set the stage, the special issue opens with a description of the history behind, the purposes of, and the steps taken to develop the PDM, and the next article provides a compelling illustration of depth-oriented personality assessment in the context of a long-term course of psychodynamic treatment. The third and fourth articles describe how the PDM model fosters attention to dynamic processes, not just overt symptoms, and they articulate the challenges and benefits of integrating this model into both the revitalized practice of assessment and diagnosis and the research avenues that will evaluate its validity and utility. The fifth article provides a broad overview of interesting experimental research on implicit processes from personality, social, and cognitive psychology, with implications for understanding and assessing dynamic processes. The sixth article illustrates how a PDM-based assessment of an adolescent boy helpfully contributed to his psychodynamic therapy. Finally, the issue closes with an illuminating article describing a PDM-based training model for the graduated development of assessment and diagnosis skills in a doctoral program. Overall, this special issue helps show how the PDM can invigorate multimethod personality assessment by placing the complex idiographic understanding of a person at the center-stage in the assessment process.

Alternative method for predicting optimal insertion depth of the laryngeal tube in children.

PubMed

Kim, J T; Jeon, S Y; Kim, C S; Kim, S D; Kim, H S

2007-11-01

Little information is available about the accuracy of the teeth mark on the laryngeal tube (LT) as a guide to correct placement in children. The aim of this crossover study was to evaluate three methods for optimal insertion depth of the size (#) 2 tube in children weighing 12-25 kg. In 24 children, the LT #2 was consecutively inserted by three different methods: (A) until the thick teeth mark on the tube was aligned with the upper incisors, (B) until resistance was felt, and (C) by inserting to a depth, previously measured, of the curved distance between the cricoid cartilage and the upper incisor. In each case, the depth of insertion, the degree of effective ventilation, the presence of leakage, and the fibreoptic view were assessed. Insertion based on the teeth mark led to a shorter insertion depth and a greater incidence of inadequate ventilation compared with the other two methods. There was no difference in the adequacy of ventilation between methods B and C. The vocal cords were more easily identified with methods B (62.5%) and C (75%) than with method A (12.5%). Insertion of the LT #2 aligned with the teeth mark can result in a shallow insertion depth and inadequate ventilation. The measured distance from the cricoid cartilage to the upper incisor offers alternative guidance for correct LT insertion.

Validation of a computerized algorithm to quantify fetal heart rate deceleration area.

2018-05-16

Reliability in visual cardiotocography interpretation is unsatisfying, which has led to development of computerized cardiotocography. Computerized analysis is well established for antenatal fetal surveillance, but has yet not performed sufficiently during labor. We aimed to investigate the capacity of a new computerized algorithm compared to visual assessment in identifying intrapartum fetal heart rate baseline and decelerations. Three-hundred-and-twelve intrapartum cardiotocography tracings with variable decelerations were analysed by the computerized algorithm and visually examined by two observers, blinded to each other and the computer analysis. The width, depth and area of each deceleration was measured. Four cases (>100 variable decelerations) were subject to in-depth detailed analysis. The outcome measures were bias in seconds (width), beats per minute (depth), and beats (area) between computer and observers by using Bland-Altman analysis. Interobserver reliability was determined by calculating intraclass correlation and Spearman rank analysis. The analysis (312 cases) showed excellent intraclass correlation (0.89-0.95) and very strong Spearman correlation (0.82-0.91). The detailed analysis of > 100 decelerations in 4 cases revealed low bias between the computer and the two observers; width 1.4 and 1.4 seconds, depth 5.1 and 0.7 beats per minute, and area 0.1 and -1.7 beats. This was comparable to the bias between the two observers; 0.3 seconds (width), 4.4 beats per minute (depth), and 1.7 beats (area). The intraclass correlation was excellent (0.90-0.98). A novel computerized algorithm for intrapartum cardiotocography analysis is as accurate as gold standard visual assessment with high correlation and low bias. This article is protected by copyright.

2015-01-01

Despite the rapid growth of retail clinics (RCs), literature is limited in terms of how these facilities offer preventive services, particularly vaccination services. The purpose of this study was to obtain an in-depth understanding of the RC business model pertaining to vaccine offerings, profitability, and decision making. From March to June 2009, we conducted 15 interviews with key individuals from three types of organizations: 12 representatives of RC corporations, 2 representatives of retail hosts (i.e., stores in which the RCs are located), and 1 representative of an industry association. We analyzed interview transcripts qualitatively. Our results indicate that consumer demand and profitability were the main drivers in offering vaccinations. RCs in this sample primarily offered vaccinations to adults and adolescents, and they were not well integrated with local public health and immunization registries. Our findings demonstrate the potential for stronger linkages with public health in these settings. The findings also may help inform future research to increase patient access to vaccination services at RCs.

Negotiation as a form of persuasion: arguments in first offers.

PubMed

Maaravi, Yossi; Ganzach, Yoav; Pazy, Asya

2011-08-01

In this article we examined aspects of negotiation within a persuasion framework. Specifically, we investigated how the provision of arguments that justified the first offer in a negotiation affected the behavior of the parties, namely, how it influenced counteroffers and settlement prices. In a series of 4 experiments and 2 pilot studies, we demonstrated that when the generation of counterarguments was easy, negotiators who did not add arguments to their first offers achieved superior results compared with negotiators who used arguments to justify their first offer. We hypothesized and provided evidence that adding arguments to a first offer was likely to cause the responding party to search for counterarguments, and this, in turn, led him or her to present counteroffers that were further away from the first offer.

Nonlinear multimodal model for TLD of irregular tank geometry and small fluid depth

NASA Astrophysics Data System (ADS)

Love, J. S.; Tait, M. J.

2013-11-01

Tuned liquid dampers (TLDs) utilize sloshing fluid to absorb and dissipate structural vibrational energy. TLDs of irregular or complex tank geometry may be required in practice to avoid tank interference with fixed structural or mechanical components. The literature offers few analytical models to predict the response of this type of TLD, particularly when the fluid depth is small. In this paper, a multimodal model is developed utilizing a Boussinesq-type modal theory which is valid for small TLD fluid depths. The Bateman-Luke variational principle is employed to develop a system of coupled nonlinear ordinary differential equations which describe the fluid response when the tank is subjected to base excitation. Energy dissipation is incorporated into the model from the inclusion of damping screens. The fluid model is used to describe the response of a 2D structure-TLD system when the structure is subjected to external loading and the TLD tank geometry is irregular.

The Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial and Its Associated Research Resource

PubMed Central

2013-01-01

The Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial is a large-scale research effort conducted by the National Cancer Institute. PLCO offers an example of coordinated research by both the extramural and intramural communities of the National Institutes of Health. The purpose of this article is to describe the PLCO research resource and how it is managed and to assess the productivity and the costs associated with this resource. Such an in-depth analysis of a single large-scale project can shed light on questions such as how large-scale projects should be managed, what metrics should be used to assess productivity, and how costs can be compared with productivity metrics. A comprehensive publication analysis identified 335 primary research publications resulting from research using PLCO data and biospecimens from 2000 to 2012. By the end of 2012, a total of 9679 citations (excluding self-citations) have resulted from this body of research publications, with an average of 29.7 citations per article, and an h index of 45, which is comparable with other large-scale studies, such as the Nurses’ Health Study. In terms of impact on public health, PLCO trial results have been used by the US Preventive Services Task Force in making recommendations concerning prostate and ovarian cancer screening. The overall cost of PLCO was $454 million over 20 years, adjusted to 2011 dollars, with approximately $37 million for the collection, processing, and storage of biospecimens, including blood samples, buccal cells, and pathology tissues.

Berger, Arthur Asa

2016-01-01

This article deals with a typology of 45 techniques of humor that I found when doing research on the mechanisms that generate humor in texts, lists the techniques and applies them to a Jewish joke. It references the work of Vladimir Propp on folktales as analogous in that both are concerned with mechanisms in text that generate meaning. It also deals with four theories about why people find texts humorous, defines the joke as a short narrative with a punch line that is meant to generate mirthful laughter and defines Jewish humor as being about Jewish people and culture as told by Jewish people. It offers a paradigmatic analysis of the joke, and offers some insights into why Jewish people developed their distinctive kind of humor. This article is an enhanced and expanded version of an article which was published in a Chinese semiotics journal (doi:10.1515/css-2015-0022). PMID:27547262

Volumetric 3D display with multi-layered active screens for enhanced the depth perception (Conference Presentation)

Three-dimensional (3D) display technology has been studied actively because it can offer more realistic images compared to the conventional 2D display. Various psychological factors such as accommodation, binocular parallax, convergence and motion parallax are used to recognize a 3D image. For glass-type 3D displays, they use only the binocular disparity in 3D depth cues. However, this method cause visual fatigue and headaches due to accommodation conflict and distorted depth perception. Thus, the hologram and volumetric display are expected to be an ideal 3D display. Holographic displays can represent realistic images satisfying the entire factors of depth perception. But, it require tremendous amount of data and fast signal processing. The volumetric 3D displays can represent images using voxel which is a physical volume. However, it is required for large data to represent the depth information on voxel. In order to simply encode 3D information, the compact type of depth fused 3D (DFD) display, which can create polarization distributed depth map (PDDM) image having both 2D color image and depth image is introduced. In this paper, a new volumetric 3D display system is shown by using PDDM image controlled by polarization controller. In order to introduce PDDM image, polarization states of the light through spatial light modulator (SLM) was analyzed by Stokes parameter depending on the gray level. Based on the analysis, polarization controller is properly designed to convert PDDM image into sectioned depth images. After synchronizing PDDM images with active screens, we can realize reconstructed 3D image.
