Collaborating With Youth in School Health Promotion Initiatives With Photovoice.

PubMed

Lofton, Saria; Bergren, Martha Dewey

2018-06-01

Photovoice, a community-based approach that is being embraced in school settings, can help to nurture collaborations with youth, particularly adolescents, and engage them in the development of social policy and health promotion projects. Photovoice is an approach that positions school nurses to inspire youth to take ownership of health promotion issues that directly affect them in the school and in their communities. Engaging youth in Photovoice not only allows advocates to directly work with youth but also promotes critical thinking and the exploration of topics that may not otherwise be considered. Photovoice raises awareness about issues through critical dialogue and is well suited to engage youth and provide a channel for youth to assert their voices.

Examining How Media Literacy and Personality Factors Predict Skepticism Toward Alcohol Advertising.

PubMed

Austin, Erica Weintraub; Muldrow, Adrienne; Austin, Bruce W

2016-05-01

To examine the potential effectiveness of media literacy education in the context of well-established personality factors, a survey of 472 young adults, focused on the issue of alcohol marketing messages, examined how individual differences in personality associate with constructs representing aspects of media literacy. The results showed that need for cognition predicted social expectancies and wishful identification with media portrayals in alcohol advertising only through critical thinking about media sources and media content, which are foci of media literacy education. Need for affect did not associate with increased or diminished levels of critical thinking. Critical thinking about sources and messages affected skepticism, represented by expectancies through wishful identification, consistent with the message interpretation process model. The results support the view that critical thinking about media sources is an important precursor to critical thinking about media messages. The results also suggest that critical thinking about media (i.e., media literacy) reflects more than personality characteristics and can affect wishful identification with role models observed in media, which appears to be a key influence on decision making. This adds support to the view that media literacy education can improve decision making across personality types regarding alcohol use by decreasing the potential influence of alcohol marketing messages.

NASA Astrophysics Data System (ADS)

Yokogawa, Shinji; Kunii, Kyousuke

2018-07-01

In this paper, a framework based on reliability physics is proposed for adopting fault tree analysis (FTA) to the on-chip interconnect system of a semiconductor. By integrating expert knowledge and experience regarding the possibilities of failure on basic events, critical issues of on-chip interconnect reliability will be evaluated by FTA. In particular, FTA is used to identify the minimal cut sets with high risk priority. Critical events affecting the on-chip interconnect reliability are identified and discussed from the viewpoint of long-term reliability assessment. The moisture impact is evaluated as an external event.

Guidelines for Electromagnetic Interference Testing of Power Plant Equipment: Revision 3 to TR-102323

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

J. Cunningham and J. Shank

2004-11-01

To continue meeting safety and reliability requirements while controlling costs, operators of nuclear power plants must be able to replace and upgrade equipment in a cost-effective manner. One issue that has been problematic for new plant equipment and especially for digital instrumentation and control (I&C) systems in recent years is electromagnetic compatibility (EMC). The EMC issue usually involves testing to show that critical equipment will not be adversely affected by electromagnetic interference (EMI) in the plant environment. This guide will help nuclear plant engineers address EMC issues and qualification testing in a consistent, comprehensive manner.

Gender, religion, and sociopolitical issues in cross-cultural online education.

PubMed

Zaidi, Zareen; Verstegen, Daniëlle; Naqvi, Rahat; Morahan, Page; Dornan, Tim

2016-05-01

Cross-cultural education is thought to develop critical consciousness of how unequal distributions of power and privilege affect people's health. Learners in different sociopolitical settings can join together in developing critical consciousness-awareness of power and privilege dynamics in society-by means of communication technology. The aim of this research was to define strengths and limitations of existing cross-cultural discussions in generating critical consciousness. The setting was the FAIMER international fellowship program for mid-career interdisciplinary health faculty, whose goal is to foster global advancement of health professions education. Fellows take part in participant-led, online, written, task-focused discussions on topics like professionalism, community health, and leadership. We reflexively identified text that brought sociopolitical topics into the online environment during the years 2011 and 2012 and used a discourse analysis toolset to make our content analysis relevant to critical consciousness. While references to participants' cultures and backgrounds were infrequent, narratives of political-, gender-, religion-, and other culture-related topics did emerge. When participants gave accounts of their experiences and exchanged cross-cultural stories, they were more likely to develop ad hoc networks to support one another in facing those issues than explore issues relating to the development of critical consciousness. We suggest that cross-cultural discussions need to be facilitated actively to transform learners' frames of reference, create critical consciousness, and develop cultural competence. Further research is needed into how to provide a safe environment for such learning and provide faculty development for the skills needed to facilitate these exchanges.

2014-10-01

THE EDITORS provide a sound introduction to ethics, law and professional issues in health care. Scenarios before each chapter help the reader to digest and comprehend the information. My only criticism is that it is not directly relevant to nursing alone. Although there is some benefit in being aware of how other practitioners may be affected by these issues, another book aimed at nurses would be more appropriate. Later chapters about responding to unprofessional practice and promoting professional healthcare practice may be of more interest to nursing students and recently qualified healthcare professionals.

Study of variables affecting critical value notification in a laboratory catering to tertiary care hospital.

PubMed

Agarwal, Rachna; Chhillar, Neelam; Tripathi, Chandra B

2015-01-01

During post-analytical phase, critical value notification to responsible caregiver in a timely manner has potential to improve patient safety which requires cooperative efforts between laboratory personnel and caregivers. It is widely accepted by hospital accreditors that ineffective notification can lead to diagnostic errors that potentially harm patients and are preventable. The objective of the study was to assess the variables affecting critical value notification, their role in affecting it's quality and approaches to improve it. In the present study 1,187 critical values were analysed in the Clinical Chemistry Laboratory catering to tertiary care hospital for neuropsychiatric diseases. During 25 months of study period, we evaluated critical value notification with respect to clinical care area, caregiver to whom it was notified and timeliness of notification. During the study period (25 months), the laboratory obtained 1,279 critical values in clinical chemistry. The analytes most commonly notified were sodium and potassium (20.97 & 20.8 % of total critical results). Analysis of critical value notification versus area of care showed that critical value notification was high in ICU and emergency area followed by inpatients and 64.61 % critical values were notified between 30 and 120 min after receiving the samples. It was found that failure to notify the responsible caregiver in timely manner represent an important patient safety issue and may lead to diagnostic errors. The major area of concern are notification of critical value for outpatient samples, incompleteness of test requisition forms regarding illegible writing, lack of information of treating physician and location of test ordering and difficulty in contacting the responsible caregiver.

The question of oxide containment during processing and storage has become a primary concern when considering the continued operability of the Plutonium Facility (PF-4) at Los Alamos National Laboratory (LANL). An Evaluation of the Safety of the Situation (ESS), “Potential for Criticality in a Glovebox Due to a Fire” (TA55-ESS-14-002-R2, since revised to R3) first issued in May, 2014 summarizes these concerns: “The safety issue of fire water potentially entering a glovebox is: the potential for the water to accumulate in the bottom of a glovebox and result in an inadvertent criticality due to the presence of fissionable materials inmore » the glovebox locations and the increased reflection and moderation of neutrons from the fire water accumulation.” As a result, the existing documented safety analysis (DSA) was judged inadequate and, while it explicitly considered the potential for criticality resulting from water intrusion into gloveboxes, criticality safety evaluation documents (CSEDs) for the affected locations did not evaluate the potential for fire water intrusion into a glovebox.« less

PubMed

Kincses, Péter; Kovács, Norbert; Karádi, Kázmér; Kállai, János

2015-03-22

This paper is a summary report on the basic questions of the biopsychosocial approach to Parkinson's disease. It deals with cognitive, affective and psychological health issues which significantly influence the outcome of the physical rehabilitation. In spite of the unchanged cognitive status, the psychological burden of the changes in the quality of life, the obstruction, the change in the affective tone, and the shrinking ability to fulfil social roles decrease the patient's quality of life. An interdisciplinary approach is best suited for mitigating these effects. Not only the patient but also his/her family and environment is seriously affected by the disease and its consequences. Treatment and rehabilitation options for increasing or maintaining the quality of life of the affected patients are diverse, and significantly depend on the features of the health care system. The authors believe that the following review emphasizing health psychological principles may contribute to the work of professionals working in clinical and rehabilitational fields and through them may increase the quality of life of patients and their family.

Real-Time Monitoring of Critical Care Analytes in the Bloodstream with Chemical Sensors: Progress and Challenges.

PubMed

Frost, Megan C; Meyerhoff, Mark E

2015-01-01

We review approaches and challenges in developing chemical sensor-based methods to accurately and continuously monitor levels of key analytes in blood related directly to the status of critically ill hospitalized patients. Electrochemical and optical sensor-based technologies have been pursued to measure important critical care species in blood [i.e., oxygen, carbon dioxide, pH, electrolytes (K(+), Na(+), Cl(-), etc.), glucose, and lactate] in real-time or near real-time. The two main configurations examined to date for achieving this goal have been intravascular catheter sensors and patient attached ex vivo sensors with intermittent blood sampling via an attached indwelling catheter. We discuss the status of these configurations and the main issues affecting the accuracy of the measurements, including cell adhesion and thrombus formation on the surface of the sensors, sensor drift, sensor selectivity, etc. Recent approaches to mitigate these nagging performance issues that have prevented these technologies from clinical use are also discussed.

Critical Science Education in a Suburban High School Chemistry Class

NASA Astrophysics Data System (ADS)

Ashby, Patrick

To improve students' scientific literacy and their general perceptions of chemistry, I enacted critical chemistry education (CCE) in two "regular level" chemistry classes with a group of 25 students in a suburban, private high school as part of this study. CCE combined the efforts of critical science educators (Fusco & Calabrese Barton, 2001; Gilbert 2013) with the performance expectations of the Next Generation Science Standards (NGSS) (NGSS Lead States, 2013a) to critically transform the traditional chemistry curriculum at this setting. Essentially, CCE engages students in the critical exploration of socially situated chemistry content knowledge and requires them to demonstrate this knowledge through the practices of science. The purpose of this study was to gauge these students development of chemistry content knowledge, chemistry interest, and critical scientific literacy (CSL) as they engaged in CCE. CSL was a construct developed for this study that necessarily combined the National Research Center's (2012) definition of scientific literacy with a critical component. As such, CSL entailed demonstrating content knowledge through the practices of science as well as the ability to critically analyze the intersections between science content and socially relevant issues. A mixed methods, critical ethnographic approach framed the collection of data from open-ended questionnaires, focus group interviews, Likert surveys, pre- and post unit tests, and student artifacts. These data revealed three main findings: (1) students began to develop CSL in specific, significant ways working through the activities of CCE, (2) student participants of CCE developed a comparable level of chemistry content understanding to students who participated in a traditional chemistry curriculum, and (3) CCE developed a group of students' perceptions of interest in chemistry. In addition to being able to teach students discipline specific content knowledge, the implications of this study are that CCE has the ability to affect students' critical science thinking in positive ways. However, to develop longer lasting, deeper critical insights that students use to participate in science-related issues outside of class, critical science education must be enacted longitudinally and across disciplines. Furthermore, it must be enacted in ways that either prompt or help students to transfer classroom learning outside of the classroom as they engage in critical issues in the classroom.

Nursing management and organizational ethics in the intensive care unit.

PubMed

Wlody, Ginger Schafer

2007-02-01

This article describes organizational ethics issues involved in nursing management of an intensive care unit. The intensive care team and medical center management have the dual responsibility to create an ethical environment in which to provide optimum patient care. Addressing organizational ethics is key to creating that ethical environment in the intensive care unit. During the past 15-20 yrs, increasing costs in health care, competitive markets, the effect of high technology, and global business changes have set the stage for business and healthcare organizational conflicts that affect the ethical environment. Studies show that critical care nurses experience moral distress and are affected by the ethical climate of both the intensive care unit and the larger organization. Thus, nursing moral distress may result in problems related to recruitment and retention of staff. Other issues with organizational ethics ramifications that may occur in the intensive care unit include patient safety issues (including those related to disruptive behavior), intensive care unit leadership style, research ethics, allocation of resources, triage, and other economic issues. Current organizational ethics conflicts are discussed, a professional practice model is described, and multidisciplinary recommendations are put forth.

Issues for small businesses with waste management.

Redmond, Janice; Walker, Elizabeth; Wang, Calvin

2008-07-01

Participation by small and medium enterprise (SME) in corporate social responsibility issues has been found to be lacking. This is a critical issue, as individually SMEs may have little impact on the environment but their collective footprint is significant. The management style and ethical stance of the owner-manager affects business decision making and therefore has a direct impact on the environmental actions of the business. Although adoption of environmental practices to create competitive advantage has been advocated, many businesses see implementation as a cost which cannot be transferred to their customers. After a brief review of pertinent literature this paper reports on an exploratory investigation into the issue. Results show that whereas owner-managers of small enterprises express concern regarding the environment, this does not then translate into better waste management practices.

Considerations for Assessing Maximum Critical Temperatures in Small Ectothermic Animals: Insights from Leaf-Cutting Ants

PubMed Central

Ribeiro, Pedro Leite; Camacho, Agustín; Navas, Carlos Arturo

2012-01-01

The thermal limits of individual animals were originally proposed as a link between animal physiology and thermal ecology. Although this link is valid in theory, the evaluation of physiological tolerances involves some problems that are the focus of this study. One rationale was that heating rates shall influence upper critical limits, so that ecological thermal limits need to consider experimental heating rates. In addition, if thermal limits are not surpassed in experiments, subsequent tests of the same individual should yield similar results or produce evidence of hardening. Finally, several non-controlled variables such as time under experimental conditions and procedures may affect results. To analyze these issues we conducted an integrative study of upper critical temperatures in a single species, the ant Atta sexdens rubropiosa, an animal model providing large numbers of individuals of diverse sizes but similar genetic makeup. Our specific aims were to test the 1) influence of heating rates in the experimental evaluation of upper critical temperature, 2) assumptions of absence of physical damage and reproducibility, and 3) sources of variance often overlooked in the thermal-limits literature; and 4) to introduce some experimental approaches that may help researchers to separate physiological and methodological issues. The upper thermal limits were influenced by both heating rates and body mass. In the latter case, the effect was physiological rather than methodological. The critical temperature decreased during subsequent tests performed on the same individual ants, even one week after the initial test. Accordingly, upper thermal limits may have been overestimated by our (and typical) protocols. Heating rates, body mass, procedures independent of temperature and other variables may affect the estimation of upper critical temperatures. Therefore, based on our data, we offer suggestions to enhance the quality of measurements, and offer recommendations to authors aiming to compile and analyze databases from the literature.

Adolescent social cognitive and affective neuroscience: past, present, and future

Blakemore, Sarah-Jayne

2012-01-01

In this article, we review three areas of research within adolescent social cognitive and affective neuroscience: (i) emotion reactivity and regulation, (ii) mentalizing and (iii) peer relations, including social rejection or acceptance as well as peer influence. The review provides a context for current contributions to the special issue of Social Cognitive and Affective Neuroscience on Adolescence, and highlights three important themes that emerge from the special issue, which are relevant to future research. First, the age of participants studied (and labels for these age groups) is a critical design consideration. We suggest that it might be logical to reduce the reliance on convenience samples of undergraduates to represent adults in psychology and cognitive neuroscience studies, since there is substantial evidence that the brain is still developing within this age range. Second, developmental researchers are broadening their scope of inquiry by testing for non-linear effects, via increased use of longitudinal strategies or much wider age ranges and larger samples. Third, there is increasing appreciation for the interrelatedness of the three areas of focus in this special issue (emotion reactivity and regulation, mentalizing, and peer relations), as well as with other areas of interest in adolescent development.

Critical elements on fitting the Bayesian multivariate Poisson Lognormal model

NASA Astrophysics Data System (ADS)

Zamzuri, Zamira Hasanah binti

2015-10-01

Motivated by a problem on fitting multivariate models to traffic accident data, a detailed discussion of the Multivariate Poisson Lognormal (MPL) model is presented. This paper reveals three critical elements on fitting the MPL model: the setting of initial estimates, hyperparameters and tuning parameters. These issues have not been highlighted in the literature. Based on simulation studies conducted, we have shown that to use the Univariate Poisson Model (UPM) estimates as starting values, at least 20,000 iterations are needed to obtain reliable final estimates. We also illustrated the sensitivity of the specific hyperparameter, which if it is not given extra attention, may affect the final estimates. The last issue is regarding the tuning parameters where they depend on the acceptance rate. Finally, a heuristic algorithm to fit the MPL model is presented. This acts as a guide to ensure that the model works satisfactorily given any data set.

Napping during night shift: practices, preferences, and perceptions of critical care and emergency department nurses.

Fallis, Wendy M; McMillan, Diana E; Edwards, Marie P

2011-04-01

Nurses working night shifts are at risk for sleep deprivation, which threatens patient and nurse safety. Little nursing research has addressed napping, an effective strategy to improve performance, reduce fatigue, and increase vigilance. To explore nurses' perceptions, experiences, barriers, and safety issues related to napping/not napping during night shift. A convenience sample of critical care nurses working night shift were interviewed to explore demographics, work schedule and environment, and napping/ not napping experiences, perceptions, and barriers. Transcripts were constantly compared, and categories and themes were identified. Participants were 13 critical care nurses with an average of 17 years' experience. Ten nurses napped regularly; 2 avoided napping because of sleep inertia. The need for and benefits of napping or not during night shift break were linked to patient and nurse safety. Ability to nap was affected by the demands of patient care and safety, staffing needs, and organizational and environmental factors. Nurses identified personal health, safety, and patient care issues supporting the need for a restorative nap during night shift. Barriers to napping exist within the organization/work environment.

Understanding Nutritional Epidemiology and Its Role in Policy12

Satija, Ambika; Yu, Edward; Willett, Walter C; Hu, Frank B

2015-01-01

Nutritional epidemiology has recently been criticized on several fronts, including the inability to measure diet accurately, and for its reliance on observational studies to address etiologic questions. In addition, several recent meta-analyses with serious methodologic flaws have arrived at erroneous or misleading conclusions, reigniting controversy over formerly settled debates. All of this has raised questions regarding the ability of nutritional epidemiologic studies to inform policy. These criticisms, to a large degree, stem from a misunderstanding of the methodologic issues of the field and the inappropriate use of the drug trial paradigm in nutrition research. The exposure of interest in nutritional epidemiology is human diet, which is a complex system of interacting components that cumulatively affect health. Consequently, nutritional epidemiology constantly faces a unique set of challenges and continually develops specific methodologies to address these. Misunderstanding these issues can lead to the nonconstructive and sometimes naive criticisms we see today. This article aims to clarify common misunderstandings of nutritional epidemiology, address challenges to the field, and discuss the utility of nutritional science in guiding policy by focusing on 5 broad questions commonly asked of the field.

Bio-ethical and legal issues in relation to HIV/AIDS: the Uganda experience.

PubMed

Yusuf, N K

1998-01-01

In Uganda, as in many other countries, there is a vacuum regarding an appropriate legal and ethical response to the HIV/AIDS pandemic. Whereas much has been done to address the HIV/AIDS pandemic in a multidisciplinary way, very little has been done regarding legal and ethical issues. Hence, cases of claimants to have cures for AIDS, spiritual healers and sale of fake drugs plus unauthorized vaccine and drug trials are on the increase. The rights and needs of people infected with HIV/AIDS are not adequately addressed. The property rights of those affected by the pandemic continue to be abused. Therefore there is need to mobilize doctors, lawyers and human rights activists who should advocate and address these issues. This paper therefore highlights the critical bio-ethical and legal issues in relation to HIV/AIDS.

Shared decision making (SDM) is a model of patient-provider communication. Little is known about the role of SDM in health disparities among Asian American and Pacific Islander (AAPI) sexual and gender minorities (SGM). We illustrate how issues at the intersection of AAPI and SGM identities affect SDM processes and health outcomes. We discuss experiences of AAPI SGM that are affected by AAPI heterogeneity, SGM stigma, multiple minority group identities, and sources of discrimination. Recommendations for clinical practice, research, policy, community development, and education are offered.

The critical thinking curriculum model

NASA Astrophysics Data System (ADS)

Robertson, William Haviland

The Critical Thinking Curriculum Model (CTCM) utilizes a multidisciplinary approach that integrates effective learning and teaching practices with computer technology. The model is designed to be flexible within a curriculum, an example for teachers to follow, where they can plug in their own critical issue. This process engages students in collaborative research that can be shared in the classroom, across the country or around the globe. The CTCM features open-ended and collaborative activities that deal with current, real world issues which leaders are attempting to solve. As implemented in the Critical Issues Forum (CIF), an educational program administered by Los Alamos National Laboratory (LANL), the CTCM encompasses the political, social/cultural, economic, and scientific realms in the context of a current global issue. In this way, students realize the importance of their schooling by applying their efforts to an endeavor that ultimately will affect their future. This study measures student attitudes toward science and technology and the changes that result from immersion in the CTCM. It also assesses the differences in student learning in science content and problem solving for students involved in the CTCM. A sample of 24 students participated in classrooms at two separate high schools in New Mexico. The evaluation results were analyzed using SPSS in a MANOVA format in order to determine the significance of the between and within-subjects effects. A comparison ANOVA was done for each two-way MANOVA to see if the comparison groups were equal. Significant findings were validated using the Scheffe test in a Post Hoc analysis. Demographic information for the sample population was recorded and tracked, including self-assessments of computer use and availability. Overall, the results indicated that the CTCM did help to increase science content understanding and problem-solving skills for students, thereby positively effecting critical thinking. No matter if the students liked science or not, enjoyed computers or not, the CTCM approach helped to increase science content understanding and problem-solving skills. The CTCM clearly provides an educational framework that can aid all students in the development of critical thinking skills.

Yb-fibre Laser Welding of 6 mm Duplex Stainless Steel 2205

NASA Astrophysics Data System (ADS)

Bolut, M.; Kong, C. Y.; Blackburn, J.; Cashell, K. A.; Hobson, P. R.

Duplex stainless steel (DSS) is one of the materials of choice for structural and nuclear applications, having high strength and good corrosion resistance when compared with other grades of stainless steel. The welding process used to join these materials is critical as transformation of the microstructure during welding directly affects the material properties. High power laser welding has recently seen an increase in research interest as it offers both speed and flexibility. This paper presents an investigation into the important parameters affecting laser welding of DSS grade 2205, with particular focus given to the critical issue of phase transformation during welding. Bead-on-plate melt-run trials without filler material were performed on 6mm thick plates using a 5 kW Yb-fibre laser. The laser beam was characterized and a Design of Experiment approach was used to quantify the impact of the process parameters. Optical metallographic methods were used to examine the resulting microstructures.

We examined views on rectal microbicides (RMs), a potential HIV prevention option, among men who have sex with men and transgender women in 3 South American cities. During September 2009 to September 2010, we conducted 10 focus groups and 36 in-depth interviews (n = 140) in Lima and Iquitos, Peru, and Guayaquil, Ecuador, to examine 5 RM domains: knowledge, thoughts and opinions about RM as an HIV prevention tool, use, condoms, and social concerns. We coded emergent themes in recorded and transcribed data sets and extracted representative quotes. We collected sociodemographic information with a self-administered questionnaire. RM issues identified included limited knowledge; concerns regarding plausibility, side effects, and efficacy; impact on condom use; target users (insertive vs receptive partners); and access concerns. Understanding the sociocultural issues affecting RMs is critical to their uptake and should be addressed prior to product launch.

Prior research indicates that Facebook usage predicts declines in subjective well-being over time. How does this come about? We examined this issue in 2 studies using experimental and field methods. In Study 1, cueing people in the laboratory to use Facebook passively (rather than actively) led to declines in affective well-being over time. Study 2 replicated these findings in the field using experience-sampling techniques. It also demonstrated how passive Facebook usage leads to declines in affective well-being: by increasing envy. Critically, the relationship between passive Facebook usage and changes in affective well-being remained significant when controlling for active Facebook use, non-Facebook online social network usage, and direct social interactions, highlighting the specificity of this result. These findings demonstrate that passive Facebook usage undermines affective well-being. (c) 2015 APA, all rights reserved).

We discuss issues associated with bacteriorhodopsin (BR) materials and films that affect optical performance in holographic applications. For the D85N variant, some critical parameters include degree of hydration and recording wavelength. The quantum efficiency of the molecular state transition is observed to be apparently dependent on the illumination wavelength. We explain this effect by modeling the photo-activity of the D85N variant as two competing photocycles between the 9-cis and 13-cis retinal configurations. We are able to determine the pure excited P-state absorbance spectrum from the ground state spectrum and mixed population spectra obtained by bleaching to steady-state conditions.

The Brazilian National AIDS Program is widely recognized as the leading example of an integrated HIV/AIDS prevention, care, and treatment program in a developing country. We critically analyze the Brazilian experience, distinguishing those elements that are unique to Brazil from the programmatic and policy decisions that can aid the development of similar programs in other low- and middle-income and developing countries. Among the critical issues that are discussed are human rights and solidarity, the interface of politics and public health, sexuality and culture, the integration of prevention and treatment, the transition from an epidemic rooted among men who have sex with men to one that increasingly affects women, and special prevention and treatment programs for injection drug users.

The acceptance of the Digital Imaging and Communication in Medicine (DICOM) standard and the Compact Disk-Recordable (CD-R) as the interchange medium have been critical developments for laboratories that need to move forward on the cine replacement front, while at the same time retain a means to communicate with other centers. One remaining essential component which has not been satisfactorily addressed is the issue of how digital image data should be archived within an institution. Every laboratory must consider the diverse issues which affect the choice of a digital archiving system. These factors include technical and economic issues, along with the clinical routines prevailing in their laboratory. A complete understanding of the issues will lead to the formulation of multiple options which may prove acceptable and will help to overcome the last obstacle which remains for the complete replacement of cine film in the cardiac catheterization laboratory.

2016-07-01

Burnout syndrome (BOS) occurs in all types of health care professionals and is especially common in individuals who care for critically ill patients. The development of BOS is related to an imbalance of personal characteristics of the employee and work-related issues or other organizational factors. BOS is associated with many deleterious consequences, including increased rates of job turnover, reduced patient satisfaction, and decreased quality of care. BOS also directly affects the mental health and physical well-being of the many critical care physicians, nurses, and other health care professionals who practice worldwide. Until recently, BOS and other psychological disorders in critical care health care professionals remained relatively unrecognized. To raise awareness of BOS, the Critical Care Societies Collaborative (CCSC) developed this call to action. The present article reviews the diagnostic criteria, prevalence, causative factors, and consequences of BOS. It also discusses potential interventions that may be used to prevent and treat BOS. Finally, we urge multiple stakeholders to help mitigate the development of BOS in critical care health care professionals and diminish the harmful consequences of BOS, both for critical care health care professionals and for patients. ©2016 American Association of Critical-Care Nurses.

Nutritional epidemiology has recently been criticized on several fronts, including the inability to measure diet accurately, and for its reliance on observational studies to address etiologic questions. In addition, several recent meta-analyses with serious methodologic flaws have arrived at erroneous or misleading conclusions, reigniting controversy over formerly settled debates. All of this has raised questions regarding the ability of nutritional epidemiologic studies to inform policy. These criticisms, to a large degree, stem from a misunderstanding of the methodologic issues of the field and the inappropriate use of the drug trial paradigm in nutrition research. The exposure of interest in nutritional epidemiology is human diet, which is a complex system of interacting components that cumulatively affect health. Consequently, nutritional epidemiology constantly faces a unique set of challenges and continually develops specific methodologies to address these. Misunderstanding these issues can lead to the nonconstructive and sometimes naive criticisms we see today. This article aims to clarify common misunderstandings of nutritional epidemiology, address challenges to the field, and discuss the utility of nutritional science in guiding policy by focusing on 5 broad questions commonly asked of the field. © 2015 American Society for Nutrition.

Under the situation of an urban environment, noise has been a critical issue in affecting the indoor environment. A reliable approach is required for evaluation of the community noise as one factor of anthrophonic in the urban environment. This research investigates the level of noise exposure from different community noise sources and elaborates the advantage of the noise disadvantages for soundscape innovation. Integrated building element design as a protector for noise control and speech intelligibility compliance using field experiment and MATLAB programming and modeling are also carried out. Meanwhile, for simulation analysis and building acoustic optimization, Sound Reduction-Speech Intelligibility and Reverberation Time are the main parameters for identifying tropical building model as case study object. The results show that the noise control should consider its integration with the other critical issue, thermal control, in an urban environment. The 1.1 second of reverberation time for speech activities and noise reduction more than 28.66 dBA for critical frequency (20 Hz), the speech intelligibility index could be reached more than fair assessment, 0.45. Furthermore, the environmental psychology adaptation result “Close The Opening” as the best method in high noise condition and personal adjustment as the easiest and the most adaptable way.

Self-Organizing Global Gene Expression Regulated through Criticality: Mechanism of the Cell-Fate Change

PubMed Central

Tsuchiya, Masa; Giuliani, Alessandro; Hashimoto, Midori; Erenpreisa, Jekaterina; Yoshikawa, Kenichi

2016-01-01

Background A fundamental issue in bioscience is to understand the mechanism that underlies the dynamic control of genome-wide expression through the complex temporal-spatial self-organization of the genome to regulate the change in cell fate. We address this issue by elucidating a physically motivated mechanism of self-organization. Principal Findings Building upon transcriptome experimental data for seven distinct cell fates, including early embryonic development, we demonstrate that self-organized criticality (SOC) plays an essential role in the dynamic control of global gene expression regulation at both the population and single-cell levels. The novel findings are as follows: i) Mechanism of cell-fate changes: A sandpile-type critical transition self-organizes overall expression into a few transcription response domains (critical states). A cell-fate change occurs by means of a dissipative pulse-like global perturbation in self-organization through the erasure of initial-state critical behaviors (criticality). Most notably, the reprogramming of early embryo cells destroys the zygote SOC control to initiate self-organization in the new embryonal genome, which passes through a stochastic overall expression pattern. ii) Mechanism of perturbation of SOC controls: Global perturbations in self-organization involve the temporal regulation of critical states. Quantitative evaluation of this perturbation in terminal cell fates reveals that dynamic interactions between critical states determine the critical-state coherent regulation. The occurrence of a temporal change in criticality perturbs this between-states interaction, which directly affects the entire genomic system. Surprisingly, a sub-critical state, corresponding to an ensemble of genes that shows only marginal changes in expression and consequently are considered to be devoid of any interest, plays an essential role in generating a global perturbation in self-organization directed toward the cell-fate change. Conclusion and Significance ‘Whole-genome’ regulation of gene expression through self-regulatory SOC control complements gene-by-gene fine tuning and represents a still largely unexplored non-equilibrium statistical mechanism that is responsible for the massive reprogramming of genome expression.

The cost of fear

USGS Publications Warehouse

Martin, Thomas E.

2011-01-01

What should parents do when they detect indications of more predators nearby that might eat their babies? This scenario is commonly faced by parents in the wild, and the consequences are important. The number of offspring that organisms produce has a major influence on fitness and, when averaged across a population, affects whether this population will increase or decrease. Offspring production thus has critical implications for evolution via fitness, and ecology and conservation via demography. On page 1398 of this issue, Zanette et al. (1) show that the fear of predation can, by itself, strongly affect the number of offspring produced over an annual cycle by song sparrows (see the figure).

Abstract Shared decision making (SDM) is a model of patient-provider communication. Little is known about the role of SDM in health disparities among Asian American and Pacific Islander (AAPI) sexual and gender minorities (SGM). We illustrate how issues at the intersection of AAPI and SGM identities affect SDM processes and health outcomes. We discuss experiences of AAPI SGM that are affected by AAPI heterogeneity, SGM stigma, multiple minority group identities, and sources of discrimination. Recommendations for clinical practice, research, policy, community development, and education are offered. PMID:27158858

The abdomen is a big place even in a small person. Gastrointestinal trauma can result in injury to the stomach, small bowel, colon, or rectum. Traumatic causes include blunt or penetrating trauma, such as gunshot wounds, stabbings, motor vehicle collisions, and crush injuries. Nontraumatic causes include appendicitis, Crohn disease, cancer, diverticulitis, ulcerative colitis, blockage of the bowel, and chemotherapy. The mechanism of injury will affect both the nature and severity of any resulting injuries. Treatment must address the critical and emergent nature of these injuries as well as issues that affect all trauma situations, which include management of hemodynamic instability.

Powers, B A

2001-01-01

The concept of everyday ethics was used to emphasize the moral basis of ordinary issues of daily living affecting quality of life for nursing home residents with dementia. To critically examine ethical issues of daily living affecting nursing home residents with dementia and to construct a descriptive taxonomy inductively derived from ethnographic fieldwork data. Combined anthropological methods of participant observation and in-depth interviewing were used in the natural setting of a 147-bed, voluntary, not-for-profit nursing home. Experiences of 30 residents, their family members, and nursing home staff were explored. In addition, the records of 10 ethics committee cases involving residents with dementia further enlarged the database. The taxonomy of everyday ethical issues includes the following four domains: (a) learning the limits of intervention; (b) tempering the culture of surveillance and restraint; (c) preserving the integrity of the individual; and (d) defining community norms and values. Each is representative of constellations of concerns that are grounded in the cultural and moral environment of the nursing home. Results highlight the challenges of recognizing the ethical in the ordinary, and of resolving everyday issues in ways that enhance quality of life for residents with dementia and those (family and staff) who care for them.

A Critical Care Societies Collaborative Statement: Burnout Syndrome in Critical Care Health-care Professionals. A Call for Action.

2016-07-01

Burnout syndrome (BOS) occurs in all types of health-care professionals and is especially common in individuals who care for critically ill patients. The development of BOS is related to an imbalance of personal characteristics of the employee and work-related issues or other organizational factors. BOS is associated with many deleterious consequences, including increased rates of job turnover, reduced patient satisfaction, and decreased quality of care. BOS also directly affects the mental health and physical well-being of the many critical care physicians, nurses, and other health-care professionals who practice worldwide. Until recently, BOS and other psychological disorders in critical care health-care professionals remained relatively unrecognized. To raise awareness of BOS, the Critical Care Societies Collaborative (CCSC) developed this call to action. The present article reviews the diagnostic criteria, prevalence, causative factors, and consequences of BOS. It also discusses potential interventions that may be used to prevent and treat BOS. Finally, we urge multiple stakeholders to help mitigate the development of BOS in critical care health-care professionals and diminish the harmful consequences of BOS, both for critical care health-care professionals and for patients.

Critical thinking is essential in nursing practice. Promoting critical thinking competence in clinical nurses is an important way to improve problem solving and decision-making competence to further improve the quality of patient care. However, using an adequate tool to test nurses' critical thinking competence and disposition may provide the reference criteria for clinical nurse characterization, training planning, and resource allocation for human resource management. The purpose of this study was to measure the critical thinking competence and critical thinking disposition of clinical nurses as well as to explore the related factors of critical thinking competence. Clinical nurses from four different clinical ladders selected from one medical center were stratified randomly. All qualified subjects who submitted valid questionnaires were included in the study. A Taiwan version of the modified Watson-Glaser Critical Thinking Appraisal and Critical Thinking Disposition Inventory was developed to measure the critical thinking competence and critical thinking disposition of clinical nurses. Validity was evaluated using the professional content test (content validity index = .93). Reliability was assessed with a Cronbach's alpha coefficient of .85. Data were analyzed using the SPSS for Windows (Version 12.0; SPSS Inc., Chicago, IL). Results showed that competence of interpretation was the highest critical thinking competence factor. Inference was the lowest, and reflective thinking as a critical thinking disposition was more positive. In addition, age, years of nursing experience, and experiences in other hospitals significantly influenced critical thinking competence (p < .05). Factors of age, years of experience, and nurses clinical ladder were shown to affect critical thinking disposition scores. Clinical ladder N4 nurses had the highest scores in both competence and disposition. A significant relationship was found between critical thinking competence and disposition scores, with 29.3% of the variance in critical thinking competence potentially explained by total years of nurse hospital experience. Clinical ladder and age were predictive factors for critical thinking disposition. Commonality was 27.9%. Nursing experience and clinical ladders positively affect critical thinking competence and disposition. Issues of critical thinking competence increasingly need to be measured. Therefore, appropriate tools for nursing professions should be further developed and explored for specific areas of practice.

The Oklahoma bombing. Lessons learned.

PubMed

Anteau, C M; Williams, L A

1997-06-01

The Oklahoma City bombing experience in April of 1995 provided a unique opportunity to test the effectiveness of an existing disaster plan. The critical care nurses at Columbia Presbyterian Hospital learned valuable lessons about managing intense activity, equipment and supplies, staffing resources, and visitor issues. The degree to which the bombing affected the emotional state of personnel was unanticipated, and leaders learned that critical stress management interventions should be included in every emergency preparedness plan. Additionally, recommendations include using runners for communication; assigning specific roles (supplies, staffing, triage); keeping additional staff in reserve for shift relief; ensuring ample hospital staff members are available to coordinate visitors and media; and setting up record systems to preserve continuity. The unique lessons learned as a result of this terrorist attack can be used by other critical care nurses to understand and refine disaster plans.

Evidence-based hypnotherapy for asthma: a critical review.

PubMed

Brown, Daniel

2007-04-01

Asthma is a chronic disease with intermittent acute exacerbations, characterized by obstructed airways, hyper-responsiveness, and sometimes by chronic airway inflammation. Critically reviewing evidence primarily from controlled outcome studies on hypnosis for asthma shows that hypnosis is possibly efficacious for treatment of symptom severity and illness-related behaviors and is efficacious for managing emotional states that exacerbate airway obstruction. Hypnosis is also possibly efficacious for decreasing airway obstruction and stabilizing airway hyper-responsiveness in some individuals, but there is insufficient evidence that hypnosis affects asthma's inflammatory process. Promising research needs to be replicated with larger samples and better designs with careful attention paid to the types of hypnotic suggestions given. The critical issue is not so much whether it is used but how it is used. Future outcome research must address the relative contribution of expectancies, hypnotizability, hypnotic induction, and specific suggestions.

Imbalance in the health workforce is a major concern in both developed and developing countries. It is a complex issue that encompasses a wide range of possible situations. This paper aims to contribute not only to a better understanding of the issues related to imbalance through a critical review of its definition and nature, but also to the development of an analytical framework. The framework emphasizes the number and types of factors affecting health workforce imbalances, and facilitates the development of policy tools and their assessment. Moreover, to facilitate comparisons between health workforce imbalances, a typology of imbalances is proposed that differentiates between profession/specialty imbalances, geographical imbalances, institutional and services imbalances and gender imbalances.

Ethical issues when using social media for health outside professional relationships.

PubMed

DeCamp, Matthew

2015-04-01

Social media have the potential to revolutionize health and healthcare, but fulfilling this potential requires attention to the ethical issues social media may raise. This article reviews the major ethical issues arising when social media are used for research, public health, mobile health applications, and global health. It focuses on social media use outside fiduciary relationships between healthcare professionals and patients. Emphasis is given to the potential of social media in these contexts, the ethical issues relatively unique to each, and where possible how existing ethical principles and frameworks could help navigate these issues. In some cases social media create the circumstance for particular ethical issues but also facilitate managing them, such as in informed consent for research. In other cases, disagreement exists about whether social media - despite their potential - should be used for certain purposes, such as in public health surveillance (where confidentiality represents a significant ethical concern). In still others, ethical uncertainty exists about how social media will affect ethical issues, such as inequality in global health. As social media technologies continue to develop, identifying and managing the ethical issues they raise will be critical to their success in improving health while preserving fundamental ethical values.

Toward Establishing a Realistic Benchmark for Airframe Noise Research: Issues and Challenges

NASA Technical Reports Server (NTRS)

Khorrami, Mehdi R.

2010-01-01

The availability of realistic benchmark configurations is essential to enable the validation of current Computational Aeroacoustic (CAA) methodologies and to further the development of new ideas and concepts that will foster the technologies of the next generation of CAA tools. The selection of a real-world configuration, the subsequent design and fabrication of an appropriate model for testing, and the acquisition of the necessarily comprehensive aeroacoustic data base are critical steps that demand great care and attention. In this paper, a brief account of the nose landing-gear configuration, being proposed jointly by NASA and the Gulfstream Aerospace Company as an airframe noise benchmark, is provided. The underlying thought processes and the resulting building block steps that were taken during the development of this benchmark case are given. Resolution of critical, yet conflicting issues is discussed - the desire to maintain geometric fidelity versus model modifications required to accommodate instrumentation; balancing model scale size versus Reynolds number effects; and time, cost, and facility availability versus important parameters like surface finish and installation effects. The decisions taken during the experimental phase of a study can significantly affect the ability of a CAA calculation to reproduce the prevalent flow conditions and associated measurements. For the nose landing gear, the most critical of such issues are highlighted and the compromises made to resolve them are discussed. The results of these compromises will be summarized by examining the positive attributes and shortcomings of this particular benchmark case.

Critical role of ethics in clinical management and public health response to the West Africa Ebola epidemic.

PubMed

Folayan, Morenike O; Haire, Bridget G; Brown, Brandon

2016-01-01

The devastation caused by the Ebola virus disease (EVD) outbreak in West Africa has brought to the fore a number of important ethical debates about how best to respond to a health crisis. These debates include issues related to prevention and containment, management of the health care workforce, clinical care, and research design, all of which are situated within the overarching moral problem of severe transnational disadvantage, which has very real and specific impacts upon the ability of citizens of EVD-affected countries to respond to a disease outbreak. Ethical issues related to prevention and containment include the appropriateness and scope of quarantine and isolation within and outside affected countries. The possibility of infection in health care workers impelled consideration of whether there is an obligation to provide health services where personal protection equipment is inadequate, alongside the issue of whether the health care workforce should have special access to experimental treatment and care interventions under development. In clinical care, ethical issues include the standards of care owed to people who comply with quarantine and isolation restrictions. Ethical issues in research include appropriate study design related to experimental vaccines and treatment interventions, and the sharing of data and biospecimens between research groups. The compassionate use of experimental drugs intersects both with research ethics and clinical care. The role of developed countries also came under scrutiny, and we concluded that developed countries have an obligation to contribute to the containment of EVD infection by contributing to the strengthening of local health care systems and infrastructure in an effort to provide fair benefits to communities engaged in research, ensuring that affected countries have ready and affordable access to any therapeutic or preventative interventions developed, and supporting affected countries on their way to recovery from the impact of EVD on their social and economic lives.

From what should we protect future generations: germ-line therapy or genetic screening?

PubMed

Mallia, Pierre; ten Have, Henk

2003-01-01

This paper discusses the issue of whether we have responsibilities to future generations with respect to genetic screening, including for purposes of selective abortion or discard. Future generations have been discussed at length among scholars. The concept of 'Guardian for Future Generations' is tackled and its main criticisms discussed. Whilst germ-line cures, it is argued, can only affect family trees, genetic screening and testing can have wider implications. If asking how this may affect future generations is a legitimate question and since we indeed make retrospective moral judgements, it would be wise to consider that future generations will make the same retrospective judgements on us. Moreover such technologies affect present embryos to which we indeed can be considered to have an obligation.

The egoism and altruism of intergenerational behavior.

PubMed

Wade-Benzoni, Kimberly A; Tost, Leigh Plunkett

2009-08-01

Some of the most important issues in society today affect more than one generation of people. In this article, the authors offer a conceptual overview and integration of the research on intergenerational dilemmas-decisions that entail a tradeoff between one's own self-interest in the present and the interests of other people in the future. Intergenerational decisions are characterized by a combination of intertemporal (i.e., behaviors that affect the future) and interpersonal (i.e., behaviors that affect other people) components. Research on intergenerational dilemmas identifies factors that emerge from these dimensions and how they interact with each other to influence intergenerational beneficence. Critically, phenomena that result from the intersection of these two dimensions-such as immortality striving through legacy creation-are especially important in distinguishing intergenerational decisions from other related decision contexts.

Factors affecting graded and ungraded memory loss following hippocampal lesions.

Winocur, Gordon; Moscovitch, Morris; Sekeres, Melanie J

2013-11-01

This review evaluates three current theories--Standard Consolidation (Squire & Wixted, 2011), Overshadowing (Sutherland, Sparks, & Lehmann, 2010), and Multiple Trace-Transformation (Winocur, Moscovitch, & Bontempi, 2010)--in terms of their ability to account for the role of the hippocampus in recent and remote memory in animals. Evidence, based on consistent findings from tests of spatial memory and memory for acquired food preferences, favours the transformation account, but this conclusion is undermined by inconsistent results from studies that measured contextual fear memory, probably the most commonly used test of hippocampal involvement in anterograde and retrograde memory. Resolution of this issue may depend on exercising greater control over critical factors (e.g., contextual environment, amount of pre-exposure to the conditioning chamber, the number and distribution of foot-shocks) that can affect the representation of the memory shortly after learning and over the long-term. Research strategies aimed at characterizing the neural basis of long-term consolidation/transformation, as well as other outstanding issues are discussed. Copyright © 2013 Elsevier Inc.

Interprofessional teamwork is essential for effective delivery of health care to all patients, particularly the vulnerable and underserved. This brief communication describes a pilot interprofessional learning experience designed to introduce medicine and pharmacy students to critical health issues affecting at-risk, vulnerable patients and helping students learn the value of functioning effectively in interprofessional teams. With reflective practice as an overarching principle, readings, writing assignments, a community-based immersion experience, discussion seminars, and presentations were organized to cultivate students' insights into key issues impacting the health and well-being of vulnerable patients. A written program evaluation form was used to gather students' feedback about this learning experience. Participating students evaluated this learning experience positively. Both quantitative and qualitative input indicated the usefulness of this learning experience in stimulating learners' thinking and helping them learn to work collaboratively with peers from another discipline to understand and address health issues for at-risk, vulnerable patients within their community. This pilot educational activity helped medicine and pharmacy students learn the value of functioning effectively in interprofessional teams. Given the importance of interprofessional teamwork and the increasing need to respond to the health needs of underserved populations, integrating interprofessional learning experiences in health professions training is highly relevant, feasible, and critically needed.

Searching for scientific literacy and critical pedagogy in socioscientific curricula: A critical discourse analysis

NASA Astrophysics Data System (ADS)

Cummings, Kristina M.

The omnipresence of science and technology in our society require the development of a critical and scientifically literate citizenry. However, the inclusion of socioscientific issues, which are open-ended controversial issues informed by both science and societal factors such as politics, economics, and ethics, do not guarantee the development of these skills. The purpose of this critical discourse analysis is to identify and analyze the discursive strategies used in intermediate science texts and curricula that address socioscientific topics and the extent to which the discourses are designed to promote or suppress the development of scientific literacy and a critical pedagogy. Three curricula that address the issue of energy and climate change were analyzed using Gee's (2011) building tasks and inquiry tools. The curricula were written by an education organization entitled PreSEES, a corporate-sponsored group called NEED, and a non-profit organization named Oxfam. The analysis found that the PreSEES and Oxfam curricula elevated the significance of climate change and the NEED curriculum deemphasized the issue. The PreSEES and Oxfam curricula promoted the development of scientific literacy while the NEED curricula suppressed its development. The PreSEES and Oxfam curricula both promoted the development of the critical pedagogy; however, only the Oxfam curricula provided authentic opportunities to enact sociopolitical change. The NEED curricula suppressed the development of critical pedagogy. From these findings, the following conclusions were drawn. When socioscientific issues are presented with the development of scientific literacy and critical pedagogy, the curricula allow students to develop fact-based opinions about the issue. However, curricula that address socioscientific issues without the inclusion of these skills minimize the significance of the issue and normalize the hegemonic worldview promoted by the curricula's authors. Based on these findings, additional research is necessary to confirm the connection between the way curricula address a socioscientific issue and develop or suppress scientific literacy. Additionally, further analysis is necessary to confirm the connection between corporate-sponsored curricula and the suppression of socioscientific issues, scientific literacy, and critical pedagogy. Finally, this study addressed only the intended results of the curricula. Further research is necessary to measure the actual impacts of these curricula on students.

Ethical and Moral Courage is Distress among Professional Nurses: A Workplace Issue.

PubMed

Brown, Geraldine

2015-01-01

Ethics and moral issues do impact the manner in which professional nurses perform their major duties. Moral distress often conflict with an ethical appropriate course of action that is known, but cannot be implemented. This distress has been associated with job dissatisfaction, burnout, early retirement, withdrawal from the moral dimensions of direct patient care, and others just leaving the profession altogether. In the workplace, institutions must make an assertive effort in providing resources and addressing situations that cause personal anxiety and depression that adversely affects total patient care. The American Association of Critical Care Nurses (AACN) has addressed ethical issues and moral distress in practices that support nurses with moral courage, when encountering ethical conflicts. Ask, Affirm, Assess and Act are the 4 A's that AACN believes should be a part of an organization's strategic plan to create a healthy workplace environment.

A variety of economic and programmatic issues are discussed concerning the development and deployment of a fleet of space-based solar power satellites (SSPS). The costs, uncertainties and risks associated with the current photovoltaic SSPS configuration, and with issues affecting the development of an economically viable SSPS development program are analyzed. The desirability of a low earth orbit (LEO) demonstration satellite and a geosynchronous (GEO) pilot satellite is examined and critical technology areas are identified. In addition, a preliminary examination of utility interface issues is reported. The main focus of the effort reported is the development of SSPS unit production, and operation and maintenance cost models suitable for incorporation into a risk assessment (Monte Carlo) model (RAM). It is shown that the key technology area deals with the productivity of man in space, not, as might be expected, with some hardware component technology.

This article delineates various patterns of illicit sales of drugs, especially at the retail (and near-retail) level, addressing a variety of central issues about drug sales and distribution documented during the past 30 years, including: a) the links between drug consumption and drug distribution activities; b) the various distribution roles; c) various levels of the distribution hierarchy; d) types of retail and wholesale markets; e) the association of drug distribution with nondrug associated criminality and violence. The article also will address the implications of drug distribution: whether various public policies such as supply reduction and source interdiction affect illicit drug markets, and how policing strategies and various law enforcement strategies can influence the involvement of individual participation in drug distribution activities. The overlooked contribution of treatment for “drug abuse” to reducing drug sales and distribution activities also will be considered as will other critical unresolved issues. PMID:14582578

Johnson, Bruce D

2003-01-01

This article delineates various patterns of illicit sales of drugs, especially at the retail (and near-retail) level, addressing a variety of central issues about drug sales and distribution documented during the past 30 years. including: a) the links between drug consumption and drug distribution activities; b) the various distribution roles; c) various levels of the distribution hierarchy; d) types of retail and wholesale markets; e) the association of drug distribution with nondrug associated criminality and violence. The article also will address the implications of drug distribution: whether various public policies such as supply reduction and source interdiction affect illicit drug markets, and how policing strategies and various law enforcement strategies can influence the involvement of individual participation in drug distribution activities. The overlooked contribution of treatment for "drug abuse" to reducing drug sales and distribution activities also will be considered as will other critical unresolved issues.

A mediator methylation mystery: JMJD1C demethylates MDC1 to regulate DNA repair.

PubMed

Lu, Jian; Matunis, Michael J

2013-12-01

Mediator of DNA-damage checkpoint 1 (MDMDC1) has a central role in repair of DNA double-strand breaks (DSBs) by both homologous recombination and nonhomologous end joining, and its function is regulated by post-translational phosphorylation, ubiquitylation and sumoylation. In this issue, a new study by Watanabe et al. reveals that methylation of MDMDC1 is also critical for its function in DSB repair and specifically affects repair through BRCA1-dependent homologous recombination.

Chiaramonte, Francis P.; Joshi, Jitendra A.

2004-01-01

This workshop was designed to bring the experts from the Advanced Human Support Technologies communities together to identify the most pressing and fruitful areas of research where success hinges on collaborative research between the two communities. Thus an effort was made to bring together experts in both advanced human support technologies and microgravity fluids, transport and reaction processes. Expertise was drawn from academia, national laboratories, and the federal government. The intent was to bring about a thorough exchange of ideas and develop recommendations to address the significant open design and operation issues for human support systems that are affected by fluid physics, transport and reaction processes. This report provides a summary of key discussions, findings, and recommendations.

Methodologies and systems for heterogeneous concurrent computing

NASA Technical Reports Server (NTRS)

Sunderam, V. S.

1994-01-01

Heterogeneous concurrent computing is gaining increasing acceptance as an alternative or complementary paradigm to multiprocessor-based parallel processing as well as to conventional supercomputing. While algorithmic and programming aspects of heterogeneous concurrent computing are similar to their parallel processing counterparts, system issues, partitioning and scheduling, and performance aspects are significantly different. In this paper, we discuss critical design and implementation issues in heterogeneous concurrent computing, and describe techniques for enhancing its effectiveness. In particular, we highlight the system level infrastructures that are required, aspects of parallel algorithm development that most affect performance, system capabilities and limitations, and tools and methodologies for effective computing in heterogeneous networked environments. We also present recent developments and experiences in the context of the PVM system and comment on ongoing and future work.

An Official Critical Care Societies Collaborative Statement-Burnout Syndrome in Critical Care Health-care Professionals: A Call for Action.

PubMed

Moss, Marc; Good, Vicki S; Gozal, David; Kleinpell, Ruth; Sessler, Curtis N

2016-07-01

Burnout syndrome (BOS) occurs in all types of health-care professionals and is especially common in individuals who care for critically ill patients. The development of BOS is related to an imbalance of personal characteristics of the employee and work-related issues or other organizational factors. BOS is associated with many deleterious consequences, including increased rates of job turnover, reduced patient satisfaction, and decreased quality of care. BOS also directly affects the mental health and physical well-being of the many critical care physicians, nurses, and other health-care professionals who practice worldwide. Until recently, BOS and other psychological disorders in critical care health-care professionals remained relatively unrecognized. To raise awareness of BOS, the Critical Care Societies Collaborative (CCSC) developed this call to action. The present article reviews the diagnostic criteria, prevalence, causative factors, and consequences of BOS. It also discusses potential interventions that may be used to prevent and treat BOS. Finally, we urge multiple stakeholders to help mitigate the development of BOS in critical care health-care professionals and diminish the harmful consequences of BOS, both for critical care health-care professionals and for patients.

On the need for long-term, on the order of a decade, hydro-climatic forecasts over large domains

NASA Astrophysics Data System (ADS)

Burges, S. J.

2012-12-01

All problems of hydrology have been influenced to some extent by the need to describe delivery of water to, and its movement through, the critical zone. The nature of the questions and the level of required quantitative description have changed with time, but all involve accurate accounting of all components of the hydrologic cycle. The broadest issues involve the temporal and spatial distributions of excess (floods) or too little (droughts) water. The spatial domains can range from small catchments to major fractions of continents. The temporal domains range from relatively short-term, on the order of hours to days to a few months, to multiple decades. Hydrologic engineers have long recognized the need to offer designs for human occupied catchments that accommodate hydrologic extremes (principally floods and droughts) that affect human and animal safety, for example, through disruptions to infrastructure and supply chains, food supplies, and water supplies. As more has been learned about the criticality of ecosystems to the well-being of the planet, water allocation issues have become those of "water for people" and "water for ecology". These latter requirements have emphasized the need for increased accuracy of estimating water budgets, and how water (and pollutants) moves through the associated critical domain. Given the now large physical demand for societal water use (it exceeds 50% of the mean annual river flow in most conterminous US river basins) hydrologic balances that include the operation of water resource infrastructure (flood damage mitigation dams and levees, storage reservoirs for municipal and industrial water, irrigation and ecological preservation) have become the norm. In most basins the storage reservoirs are relatively small (few store more than the mean annual flow of rivers) and long-term hydrological forecasting has become a major issue. Whether the issue is floods or droughts, there is now a pressing need for societally useful forecasts from seasonal to up to a decade or so ahead. I address issues that need to be considered by the ocean and hydro-climatology communities to find a way forward for this societally important issue.

The Behavioural Biogeosciences: Moving Beyond Evolutionary Adaptation and Innate Reasoning

NASA Astrophysics Data System (ADS)

Glynn, P. D.

2014-12-01

Human biases and heuristics reflect adaptation over our evolutionary past to frequently experienced situations that affected our survival and that provided sharp distinguished feedbacks at the level of the individual. Human behavior, however, is not well adapted to the more diffusely experienced (i.e. less immediately/locally acute) problems and issues that scientists and society often seek to address today. Several human biases are identified that affect how science is conducted and used. These biases include an innate discounting of less visible phenomena/systems and of long-term perspectives; as well as a general lack of consideration of the coupling between the resources that we use and the waste that we consequently produce. Other biases include strong beliefs in human exceptionalism and separatedness from "nature". Francis Bacon (The New Organon, 1620) provided a classification of the factors, of the "idols of the mind", that bias pursuit of greater knowledge. How can we address these biases and the factors that affect behaviour and pursuit of knowledge; and ultimately impact the sustainability and resilience of human societies, resources and environments? A process for critical analysis is proposed that solicits explicit accounting and cognizance of these potential human biases and factors. Seeking a greater diversity of independant perspectives is essential: in both the conduct of science and in its application to the management of natural resources and environments. Accountability, traceability and structured processes are critical in this endeavor. The scientific methods designed during the industrial revolution are necessary, but insufficient, in addressing the issues of today. A new area of study in "the behavioral biogeosciences" is suggested that counters, or at least closely re-evaluates, our normal (i.e. adapted) human priorities of observation and study, as well as our judgements and decision-making.

Nurse's perceptions of physiotherapists in critical care team: Report of a qualitative study.

Interprofessional relationship plays a major role in effective patient care. Specialized units such as critical care require multidisciplinary care where perception about every members role may affect the delivery of patient care. The objective of this study was to find out nurses' perceptions of the role of physiotherapists in the critical care team. Qualitative study by using semi-structured interview was conducted among the qualified nurses working in the Intensive Care Unit of a tertiary care hospital. The interview consisted of 19 questions divided into 3 sections. Interviews were audio recorded and transcribed. In-depth content analysis was carried out to identify major themes in relation to the research question. Analysis identified five major issues which included role and image of a physiotherapist, effectiveness of treatment, communications, teamwork, and interprofessional relations. Physiotherapists were perceived to be an important member of the critical team with the role of mobilizing the patients. The respondents admitted that there existed limitations in interprofessional relationship. Nurses perceived the role of physiotherapist in the critical care unit as an integral part and agreed on the need for inclusion of therapist multidisciplinary critical care team.

Ethics in worksite health programming: who is served?

PubMed

Roman, P M; Blum, T C

1987-01-01

As relatively new innovations in the workplace, employee assistance and wellness/health promotion programs have not yet established clear identities. Thus ethical practices have not been fully considered or discussed. Based on extensive research experience with employee assistance programs, ethical issues are considered at three levels. Of primary concern are ethical issues affecting the individual employee, of which the scope of perceived or expected service relationships between employees and EAP coordinators is critical. There are tendencies to transfer models of community or private practice to the worksite, but the relationships both prescribed and implied at the worksite require that a different pattern of clinical relationships obtain. At the organizational level, it is critical for the worksite practitioners to be conscious of their authority in translating scientific data into recommended practices at the worksite and in transforming equivocal data and health practices into organizational norms. Finally, at the level of interorganizational relationships the worksite health program practitioner needs to be aware of the risks of becoming drawn into overly intimate relationships with external organizations who may come to benefit by special treatment that such relationships generate.

Affective disorders and sexual function: from neuroscience to clinic.

PubMed

Barata, Bernardo C

2017-11-01

Sexual dysfunction is a frequent issue in patients with affective disorders, affecting its quality of life and posing challenges to the approach of these patients. In recent years, human sexuality has attracted interest from the scientific community, and today we have a much deeper knowledge of the mechanisms involved in the sexual response. Paraphilias or sexual dysfunctions like low sexual desire, premature ejaculation, and erectile dysfunction, are frequent in affective disorders, and the frequency of each sexual problem varies according to the affective disorder. Comparing what is currently known about the sexual response with the main neurobiological findings of depressive, anxiety, obsessive-compulsive and posttraumatic stress disorders, it is possible to better understand specific sexual complaints of patients with these disorders. A better understanding of sexual function in affective disorders may help clinicians to choose treatments more suited to specific needs of these patients. Although the current state of science already allows us to have some understanding about sexual function in affective disorders, this critical area of research is still in its infancy, waiting for more investment.

New Mexico, one of four states on the U.S./Mexico border, is faced with a pressing concern--lack of water. Since the region is either arid or semiarid, it is chronically short of continually available surface-water resources. Groundwater resources are used beyond their capacity to be recharged, and most surface-water resources are used to the maximum. The quality of groundwater varies widely. As a result of nonpoint- and point-source contamination, as well as natural occurrence, water in some areas is too salty or has high levels of natural uranium, fluoride, or arsenic. To date, the New Mexico Environment Department (NMED) has recognized 1,400 cases of groundwater contamination, and 1,907 water supply wells have been affected (NMED, 2001a). Of approximate 4,000 miles of coninously flowing rivers and streams in New Mexico, 92 perent are affected by nonpoint sources of pollution (NMED, 2001b). Numerous critical water issues exist along the New Mexico/Mexico border as a result of the impending critical issue of water availability, usage, and quality, as well as the fast-growing population. Related public health problems along the New Mexico/Mexico border are indicative of the need for a holistic, concrete, and sustainable solution to meet water demands in New Mexico. In order to accomplish the goals an objectives of Border XXI, Healthy People 2010, and Heathy Border 2010, a comprehensive statewide water management plan is needed. Solutions to the water demands of the region will be addressed in a subsequent manuscript.

2018-01-30

To determine if pager interruptions affect operative time, safety, or complications and management of pager issues during a simulated laparoscopic cholecystectomy. Twelve surgery resident volunteers were tested on a Simbionix Lap Mentor II simulator. Each resident performed 6 randomized simulated laparoscopic cholecystectomies; 3 with pager interruptions (INT) and 3 without pager interruptions (NO-INT). The pager interruptions were sent in the form of standardized patient vignettes and timed to distract the resident during dissection of the critical view of safety and clipping of the cystic duct. The residents were graded on a pass/fail scale for eliciting appropriate patient history and management of the pager issue. Data was extracted from the simulator for the following endpoints: operative time, safety metrics, and incidence of operative complications. The Mann-Whitney U test and contingency table analysis were used to compare the 2 groups (INT vs. NO-INT). Level I trauma center; Simulation laboratory. Twelve general surgery residents. There was no significant difference between the 2 groups in any of the operative endpoints as measured by the simulator. However, in the INT group, only 25% of the time did the surgery residents both adequately address the issue and provide effective patient management in response to the pager interruption. Pager interruptions did not affect operative time, safety, or complications during the simulated procedure. However, there were significant failures in the appropriate evaluations and management of pager issues. Consideration for diversion of patient care issues to fellow residents not operating to improve quality and safety of patient care outside the operating room requires further study. Copyright © 2018.

Evolution and depression: issues and implications.

PubMed

Gilbert, Paul

2006-03-01

Depression is well recognized to be rooted in the down-regulation of positive affect systems. This paper reviews some of the social and non-social theories that seek to explain the potential adaptive advantages of being able to tone down positive affect, and how dysfunctions in such affect control can occur in some contexts. Common to most evolutionary theories of depression is the view that loss of control over aversive events and/or major resources/rewards exert downward pressure on positive affect. Social theories, however, suggest that it is loss of control over the social environment that is particularly depressogenic. Two evolutionary theories (the attachment-loss, and the defeat-loss theories) are briefly reviewed and their interaction considered. It is suggested that phenotypes for toning down positive affect, in the face of loss of control, may become more severe in the context of socially hostile, unsupportive and/or excessively competitive environments. The paper briefly considers how human competencies for self-evaluation in relation to others, rumination, self-criticism, and modern social contexts can accentuate dysfunctional expressions of affect regulation.

Mobile health (mHealth) applications have recently proliferated, especially in low- and middle-income countries, complementing task-redistribution strategies with clinical decision support. Relatively few studies address usability and feasibility issues that may impact success or failure of implementation, and few have been conducted for non-communicable diseases such as hypertension. To conduct iterative usability and feasibility testing of a tablet-based Decision Support and Integrated Record-keeping (DESIRE) tool, a technology intended to assist rural clinicians taking care of hypertension patients at the community level in a resource-limited setting in western Kenya. Usability testing consisted of "think aloud" exercises and "mock patient encounters" with five nurses, as well as one focus group discussion. Feasibility testing consisted of semi-structured interviews of five nurses and two members of the implementation team, and one focus group discussion with nurses. Content analysis was performed using both deductive codes and significant inductive codes. Critical incidents were identified and ranked according to severity. A cause-of-error analysis was used to develop corresponding design change suggestions. Fifty-seven critical incidents were identified in usability testing, 21 of which were unique. The cause-of-error analysis yielded 23 design change suggestions. Feasibility themes included barriers to implementation along both human and technical axes, facilitators to implementation, provider issues, patient issues and feature requests. This participatory, iterative human-centered design process revealed previously unaddressed usability and feasibility issues affecting the implementation of the DESIRE tool in western Kenya. In addition to well-known technical issues, we highlight the importance of human factors that can impact implementation of mHealth interventions. Copyright © 2015 Elsevier Ireland Ltd.

The Impact of Positive and Negative Affect and Issue Framing on Issue Interpretation and Risk Taking.

PubMed

Mittal; Ross

1998-12-01

Two studies examined the influence of transient affective states and issue framing on issue interpretation and risk taking within the context of strategic decision making. In Study 1, participants in whom transient positive or negative affective states were induced by reading a short story showed systematic differences in issue interpretation and risk taking in a strategic decision making context. Compared to negative mood participants, those in a positive mood were more likely to interpret the strategic issue as an opportunity and displayed lower levels of risk taking. Study 2 replicated and extended these results by crossing affective states with threat and opportunity frames. Results showed that framing an issue (as a threat or an opportunity) had a stronger impact on issue interpretation among negative affect participants than among positive affect participants. Affective states also moderated the impact of issue framing on risk taking: the effect of framing on risk-taking was stronger under negative rather than positive affect. These results are interpreted via information-processing and motivational effects of affect on a decision maker. Copyright 1998 Academic Press.

Perspectives on learning through research on critical issues-based science center exhibitions

NASA Astrophysics Data System (ADS)

Pedretti, Erminia G.

2004-07-01

Recently, science centers have created issues-based exhibitions as a way of communicating socioscientific subject matter to the public. Research in the last decade has investigated how critical issues-based installations promote more robust views of science, while creating effective learning environments for teaching and learning about science. The focus of this paper is to explore research conducted over a 10-year period that informs our understanding of the nature of learning through these experiences. Two specific exhibitions - Mine Games and A Question of Truth - provide the context for discussing this research. Findings suggest that critical issues-based installations challenge visitors in different ways - intellectually and emotionally. They provide experiences beyond usual phenomenon-based exhibitions and carry the potential to enhance learning by personalizing subject matter, evoking emotion, stimulating dialogue and debate, and promoting reflexivity. Critical issues-based exhibitions serve as excellent environments in which to explore the nature of learning in these nonschool settings.

Design, fiction and the medical humanities.

PubMed

Strachan, Christopher Gordon

2016-12-01

This paper sets out to explore the similarities between the developing discipline of speculative and critical design (SCD) and science fiction, and their relevance to the medical humanities. SCD looks beyond 'commercial design' to consider what sort of things we should, or should not, be designing in order to create preferable futures. It does so by extrapolating from current social, economic, political and scientific knowledge, designing artefacts, experiences and scenarios which communicate futures and alternative realities in tangible ways. By first outlying the relevance of SCD to the medical humanities, through its ability to imagine and visualise preferable healthcare futures, the paper will then discuss several recent design projects which focus on current and future ethical issues raised by emerging biotechnology. Through these projects, the paper will look at SCD's ability to provoke, engage and critique science and society, while also critically reflecting on the limitations of the evolving design discipline. Through the paper it is hoped that there can be an increased understanding of SCD and its ambitions, as well as its limitations, in order for SCD to better approach issues relating to health and wellbeing, along with other difficult and challenging issues which will affect all us today and into the (sci-fi) future.

Since 2000, the University of Kentucky's (UK's) Superfund Basic Research Program (SBRP) Community Outreach Core has provided support and guidance through Superfund Community Action through Nutrition (SCAN) programs, which meet the needs of individuals and communities affected by environmental contaminants. It has been shown that nutrition may modulate the toxicity of Superfund chemicals. SCAN programs integrate nutrition education, nutrition science research, and health communication to increase understanding of health risks associated with residing near Superfund sites. Two critical tasks must be accomplished. SCAN personnel must identify and recruit affected community members, and then, offer meaningful programs. Certain quantitative outcome measures and legal issues presented both challenges and opportunities. Community members preferred qualitative evaluation discussions, which showed increased knowledge and improved attitudes following SCAN programs. SCAN, in full partnership with affected communities, translates safe, effective nutrition information to reduce health risks associated with exposure to Superfund pollutants. PMID:18443657

2011-04-01

Climate change is a global issue in this century which has challenged the survival of living creatures affecting the life supporting systems of the earth: atmosphere, hydrosphere and lithosphere. Scientists have reached in a consensus that climate change is happening. The anthropogenic emission of greenhouse gases is responsible for global warming and therefore climate change. Climate change may directly or indirectly affect human health through a range of pathways related to temperature and precipitation. The aim of this article is to share knowledge on how climate change can affect public health in Nepal based on scientific evidence from global studies and experience gained locally. In this review attempt has been made to critically analyze the scientific studies as well as policy documents of Nepalese Government and shed light on public health impact of climate change in the context of Nepal. Detailed scientific study is recommended to discern impact of climate change on public health problems in Nepal.

Synchronous critical speed tracking in hydrostatic bearing supported rotors

NASA Technical Reports Server (NTRS)

Henderson, Thomas W.; Scharrer, Joseph K.

1989-01-01

Hydrostatic bearings used in advanced turbopump designs use the pumped propellant as the working fluid and supply the propellant to the bearing from pump discharge. The resulting rotordynamic coefficients are highly speed-dependent and in some instances can cause system natural frequencies to coincide with spin speed over a wide speed range. This paper discusses this 'synchronous tracking' phenomenon. The factors affecting it are defined, and specific examples are presented. Methods which identify synchronous tracking issues early in the design process are reported, and techniques for eliminating this undesirable characteristic are addressed.

Horizontal takeoff airbreathing-propulsion launch vehicles require near-optimal guidance and control which takes into account performance sensitivities to atmospheric characteristics while satisfying physically-derived operational constraints. A generic trajectory/control analysis tool that deepens insight into these considerations has been applied to two versions of a winged-cone vehicle model. Information that is critical to the design and trajectory of these vehicles is derived, and several unusual characteristics of the airbreathing propulsion model are shown to have potentially substantial effects on vehicle dynamics.

Space station crew safety: Human factors interaction model

NASA Technical Reports Server (NTRS)

Cohen, M. M.; Junge, M. K.

1985-01-01

A model of the various human factors issues and interactions that might affect crew safety is developed. The first step addressed systematically the central question: How is this space station different from all other spacecraft? A wide range of possible issue was identified and researched. Five major topics of human factors issues that interacted with crew safety resulted: Protocols, Critical Habitability, Work Related Issues, Crew Incapacitation and Personal Choice. Second, an interaction model was developed that would show some degree of cause and effect between objective environmental or operational conditions and the creation of potential safety hazards. The intermediary steps between these two extremes of causality were the effects on human performance and the results of degraded performance. The model contains three milestones: stressor, human performance (degraded) and safety hazard threshold. Between these milestones are two countermeasure intervention points. The first opportunity for intervention is the countermeasure against stress. If this countermeasure fails, performance degrades. The second opportunity for intervention is the countermeasure against error. If this second countermeasure fails, the threshold of a potential safety hazard may be crossed.

Central Asia is one of the most vulnerable regions on the planet earth to global climate change, depending on very fragile natural resources. The Soviet legacy has left the five countries (Kazakhstan, Tajikistan, Kyrgyzstan, Turkmenistan, and Uzbekistan) with a highly integrated system but they are facing great challenges with tensions that hinder regional coordination of food and water resources. With increasing climate variability and warming trend in the region, food and water security issues become even more crucial now and, if not addressed properly, could affect the regional stability. The long-term drivers of these two most critical elements, food and water, are climate change; the immediate and probably more drastic factors affecting the food and water security are land uses driven by institutional change and economic incentives. As a feedback, changes in land use and land cover have directly implications on water uses, food production, and lifestyles of the rural community in the region. Regional and international efforts have been made to holistically understand the cause, extent, rate and societal implications of land use changes in the region. Much of these have been understood, or under investigation by various projects, but solutions or research effort to develop solutions, to these urgent regional issues are lacking. This article, serves as an introduction to the special issue, provides a brief overview of the challenges facing the Central Asian countries and various international efforts in place that resulted in the publications of this special issue.

Music, affect, method, data: reflections on the Carroll versus Kivy debate.

PubMed

Konecni, Vladimir J

2013-01-01

The comprehensive exchange between Noel Carroll and Peter Kivy, which took place in 2007, addressed key issues in the relationship between music and affect. More than in any prior philosophical debate on this topic, experimental psychologists' methods and data played a significant role. However, to a nontrivial extent, the findings-perhaps especially the dubious-were misconstrued or misused, usually without acknowledging the existence of contrary data-based opinion within the psychology of music itself. Therefore, one objective of the present article is to identify the specific problematic features and shed light on the broader context shared by the two disciplines. A complementary goal is to examine contributions to philosophers' transgressions by music psychologists' insufficiently conscientious reporting, frequent overgeneralizations, and unawareness of philosophers' critical arguments. Another objective is to examine the current status of key concepts-the relevant music, basic emotions, mood, expression, induction, movement and dance, and methods (including introspection and experimental procedures)-thus perhaps enabling the discussion of music and affect to proceed with fewer misunderstandings. Finally, the article moves beyond the initial debate and builds on a remarkable agreement of philosophical and psychological opinion on a key issue (the induction of non-basic emotions by absolute music) to reach a new conceptual ground.

Critical Issues in Evaluating National-Level Health Data Warehouses in LMICs: Kenya Case Study.

Gesicho, Milka B; Babic, Ankica; Were, Martin C

2017-01-01

Low-Middle-Income-Countries (LMICs) are beginning to adopt national health data warehousing (NHDWs) for making strategic decisions and for improving health outcomes. Given the numerous challenges likely to be faced in establishment of NHDWs by LMICs, it is prudent that evaluations are done in relation to the data warehouses (DWs), in order to identify and mitigate critical issues that arise. When critic issues are not identified, DWs are prone to suboptimal implementation with compromised outcomes. Despite the fact that several publications exist on evaluating DWs, evaluations specific to health data warehouses are scanty, with almost none evaluating NHDWs more so in LMICs. This paper uses a systematic approach guided by an evaluation framework to identify critical issues to be considered in evaluating Kenya's NHDW.

Fracture and buckling of piezoelectric nanowires subject to an electric field

NASA Astrophysics Data System (ADS)

Zhang, Jin; Wang, Chengyuan; Adhikari, Sondipon

2013-11-01

Fracture and buckling are major failure modes of thin and long nanowires (NWs), which could be affected significantly by an electric field when piezoelectricity is involved in the NWs. This paper aims to examine the issue based on the molecular dynamics simulations, where the gallium nitride (GaN) NWs are taken as an example. The results show that the influence of the electric field is strong for the fracture and the critical buckling strains, detectable for the fracture strength but almost negligible for the critical buckling stress. In addition, the reversed effects are achieved for the fracture and the critical buckling strains. Subsequently, the Timoshenko beam model is utilized to account for the effect of the electric field on the axial buckling of the GaN NWs, where nonlocal effect is observed and characterized by the nonlocal coefficient e0a=1.1 nm. The results show that the fracture and buckling of piezoelectric NWs can be controlled by applying an electric field.

Dissolved Gases and Ice Fracturing During the Freezing of a Multicellular Organism: Lessons from Tardigrades

Kletetschka, Gunther; Hruba, Jolana

2015-01-01

Abstract Three issues are critical for successful cryopreservation of multicellular material: gases dissolved in liquid, thermal conductivity of the tissue, and localization of microstructures. Here we show that heat distribution is controlled by the gas amount dissolved in liquids and that when changing the liquid into solid, the dissolved gases either form bubbles due to the absence of space in the lattice of solids and/or are migrated toward the concentrated salt and sugar solution at the cost of amount of heat required to be removed to complete a solid-state transition. These factors affect the heat distribution in the organs to be cryopreserved. We show that the gas concentration issue controls fracturing of ice when freezing. There are volumetric changes not only when changing the liquid into solid (volume increases) but also reduction of the volume when reaching lower temperatures (volume decreases). We discuss these issues parallel with observations of the cryosurvivability of multicellular organisms, tardigrades, and discuss their analogy for cryopreservation of large organs. PMID:26309797

The value of using top-down and bottom-up approaches for building trust and transparency in biobanking.

PubMed

Meslin, Eric M

2010-01-01

With the domestic and international proliferation of biobanks and their associated connections to health information databases, scholarly attention has been turning from the ethical issues arising from the construction of biobanks to the ethical issues that emerge in their operation and management. Calls for greater transparency in governance structures, coupled with stern reminders of the value of maintaining public trust, are seen as critical components in the success of these resources. Two different approaches have been adopted for addressing these types of ethical issues: the first is a 'top-down' approach which focuses on developing policy, procedures, regulations and guidelines to aid decision-makers. The second is a 'bottom-up' approach, which begins with those who are most affected by the issues and attempts to inductively develop consensus recommendations and policy. While both approaches have merit, I argue that more work needs to be done on 'bottom-up' strategies if trust and transparency are to be more than mere slogans. Using 2 case examples from Indiana, the paper summarizes data from a set of surveys we recently conducted that address issues arising from biobanks that provide some insight into issues associated with trust and transparency.

2011 Annual Criticality Safety Program Performance Summary

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

Andrea Hoffman

The 2011 review of the INL Criticality Safety Program has determined that the program is robust and effective. The review was prepared for, and fulfills Contract Data Requirements List (CDRL) item H.20, 'Annual Criticality Safety Program performance summary that includes the status of assessments, issues, corrective actions, infractions, requirements management, training, and programmatic support.' This performance summary addresses the status of these important elements of the INL Criticality Safety Program. Assessments - Assessments in 2011 were planned and scheduled. The scheduled assessments included a Criticality Safety Program Effectiveness Review, Criticality Control Area Inspections, a Protection of Controlled Unclassified Information Inspection,more » an Assessment of Criticality Safety SQA, and this management assessment of the Criticality Safety Program. All of the assessments were completed with the exception of the 'Effectiveness Review' for SSPSF, which was delayed due to emerging work. Although minor issues were identified in the assessments, no issues or combination of issues indicated that the INL Criticality Safety Program was ineffective. The identification of issues demonstrates the importance of an assessment program to the overall health and effectiveness of the INL Criticality Safety Program. Issues and Corrective Actions - There are relatively few criticality safety related issues in the Laboratory ICAMS system. Most were identified by Criticality Safety Program assessments. No issues indicate ineffectiveness in the INL Criticality Safety Program. All of the issues are being worked and there are no imminent criticality concerns. Infractions - There was one criticality safety related violation in 2011. On January 18, 2011, it was discovered that a fuel plate bundle in the Nuclear Materials Inspection and Storage (NMIS) facility exceeded the fissionable mass limit, resulting in a technical safety requirement (TSR) violation. The TSR limits fuel plate bundles to 1085 grams U-235, which is the maximum loading of an ATR fuel element. The overloaded fuel plate bundle contained 1097 grams U-235 and was assembled under an 1100 gram U-235 limit in 1982. In 2003, the limit was reduced to 1085 grams citing a new criticality safety evaluation for ATR fuel elements. The fuel plate bundle inventories were not checked for compliance prior to implementing the reduced limit. A subsequent review of the NMIS inventory did not identify further violations. Requirements Management - The INL Criticality Safety program is organized and well documented. The source requirements for the INL Criticality Safety Program are from 10 CFR 830.204, DOE Order 420.1B, Chapter III, 'Nuclear Criticality Safety,' ANSI/ANS 8-series Industry Standards, and DOE Standards. These source requirements are documented in LRD-18001, 'INL Criticality Safety Program Requirements Manual.' The majority of the criticality safety source requirements are contained in DOE Order 420.1B because it invokes all of the ANSI/ANS 8-Series Standards. DOE Order 420.1B also invokes several DOE Standards, including DOE-STD-3007, 'Guidelines for Preparing Criticality Safety Evaluations at Department of Energy Non-Reactor Nuclear Facilities.' DOE Order 420.1B contains requirements for DOE 'Heads of Field Elements' to approve the criticality safety program and specific elements of the program, namely, the qualification of criticality staff and the method for preparing criticality safety evaluations. This was accomplished by the approval of SAR-400, 'INL Standardized Nuclear Safety Basis Manual,' Chapter 6, 'Prevention of Inadvertent Criticality.' Chapter 6 of SAR-400 contains sufficient detail and/or reference to the specific DOE and contractor documents that adequately describe the INL Criticality Safety Program per the elements specified in DOE Order 420.1B. The Safety Evaluation Report for SAR-400 specifically recognizes that the approval of SAR-400 approves the INL Criticality Safety Program. No new source requirements were released in 2011. A revision to LRD-18001 is planned for 2012 to clarify design requirements for criticality alarms. Training - Criticality Safety Engineering has developed training and provides training for many employee positions, including fissionable material handlers, facility managers, criticality safety officers, firefighters, and criticality safety engineers. Criticality safety training at the INL is a program strength. A revision to the training module developed in 2010 to supplement MFC certified fissionable material handlers (operators) training was prepared and presented in August of 2011. This training, 'Applied Science of Criticality Safety,' builds upon existing training and gives operators a better understanding of how their criticality controls are derived. Improvements to 00INL189, 'INL Criticality Safety Principles' are planned for 2012 to strengthen fissionable material handler training.« less

Space-based solar power conversion and delivery systems study. Volume 5: Economic analysis

NASA Technical Reports Server (NTRS)

1977-01-01

Space-based solar power conversion and delivery systems are studied along with a variety of economic and programmatic issues relevant to their development and deployment. The costs, uncertainties and risks associated with the current photovoltaic Satellite Solar Power System (SSPS) configuration, and issues affecting the development of an economically viable SSPS development program are addressed. In particular, the desirability of low earth orbit (LEO) and geosynchronous (GEO) test satellites is examined and critical technology areas are identified. The development of SSPS unit production (nth item), and operation and maintenance cost models suitable for incorporation into a risk assessment (Monte Carlo) model (RAM) are reported. The RAM was then used to evaluate the current SSPS configuration expected costs and cost-risk associated with this configuration. By examining differential costs and cost-risk as a function of postulated technology developments, the critical technologies, that is, those which drive costs and/or cost-risk, are identified. It is shown that the key technology area deals with productivity in space, that is, the ability to fabricate and assemble large structures in space, not, as might be expected, with some hardware component technology.

Elder self-neglect and the justice system: an essay from an interdisciplinary perspective.

PubMed

Connolly, Marie-Therese

2008-11-01

Elder self-neglect is a complex issue for the legal system-one not always easily distinguished from other types of elder abuse, neglect, and exploitation. The issue inherently implicates several disciplines, and although self-neglect is not prosecuted per se, prosecutions of other types of elder abuse, neglect, and exploitation may affect self-neglect as well. In addition, other types of legal intervention, such as guardianship actions, may serve to protect vulnerable older people, but it is critical to ensure that such interventions do not inappropriately infringe on the older person's civil liberties or result in exploitation or worse. There are daunting challenges to doing work in this field-death; ageism; medical, legal, and ethical complexities; and a chronic paucity of funding. It is nevertheless imperative that researchers expand their efforts to elucidate the nature and scope of elder self-neglect; its interplay with other forms of abuse, neglect, and exploitation; and the most effective mechanisms for intervention and prevention. Such efforts, and in particular interdisciplinary approaches to these common problems, are critical to improving care for the nation's older people and assisting millions of families and practitioners.

Critical education in resource and environmental management: Learning and empowerment for a sustainable future

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

Diduck, A.

1999-10-01

Changing rom current patterns of resource use to a sustainable and equitable economy is a complex and intractable problem. This paper suggests that critical education may form part of the solution. Critical environmental assessment (EA) education, the model explored in this paper, offers a tool for resource and environmental managers to use in managing public involvement processes. This model challenges current patterns of resource use and addresses criticisms of public involvement processes. Critical EA education, involving both cognitive development and personal empowerment, focuses on critical intelligence, problem solving and social action. The concept is offered as a means to facilitatemore » and improve public involvement and, thereby, empower local communities to take greater control of resource use decisions affecting their lives. Positive implications of critical EA education for change, complexity, uncertainty and conflict, which are four enduring themes in resource and environmental management, are discussed in the paper. The implications include: cognitive development and personal empowerment at the level of local resource communities; simplification of the often complex discourse encountered in resource management; reduction in feelings of powerlessness often experienced by members of the public in environmental assessment scenarios; a reduction of ignorance and indeterminacy regarding resource management issues; conflict resolution at the cognitive level; and, clarification of the opposing values, interests or actions at the heart of a conflict.« less

Teacher self-efficacy refers to the beliefs teachers hold regarding their capability to bring about desired instructional outcomes and may be helpful for understanding and addressing critical issues such as teacher attrition and teacher use of research-supported practices. Educating students with autism likely presents teachers with some of the most significant instructional challenges. The self-efficacy of 35 special education teachers of students with autism between the ages of 3 to 9 years was evaluated. Teachers completed rating scales that represented self-efficacy and aspects of the following 3 of Bandura's 4 sources of self-efficacy: (1) sense of mastery, (2) social persuasions, and (3) physiological/affective states. Significant associations were observed between physiological/affective states and self-efficacy, but no associations were observed for the other sources.

A Review of Consequences of Poverty on Economic Decision-Making: A Hypothesized Model of a Cognitive Mechanism.

Adamkovič, Matúš; Martončik, Marcel

2017-01-01

This review focuses on the issue of poverty affecting economic decision-making. By critically evaluating existing studies, the authors propose a structural model detailing the cognitive mechanism involved in how poverty negatively impacts economic decision-making, and explores evidence supporting the basis for the formation of this model. The suggested mechanism consists of a relationship between poverty and four other factors: (1) cognitive load (e.g., experiencing negative affect and stress); (2) executive functions (e.g., attention, working memory, and self-control); (3) intuition/deliberation in decision-making; and (4) economic decision-making (e.g., time-discounting and risk preference), with a final addition of financial literacy as a covariate. This paper focuses on shortfalls in published research, and delves further into the proposed model.

Sources, mechanisms, and consequences of chemical-induced mitochondrial toxicity

Meyer, Joel N.; Chan, Sherine S. L.

2017-01-01

Mitochondrial function is critical for health, as demonstrated by the effects of mitochondrial toxicity, mutations in genes encoding mitochondrial proteins, and the role of mitochondrial dysfunction in many chronic diseases. However, much basic mitochondrial biology is still being discovered. Furthermore, the details of how different environmental exposures affect mitochondria, how mitochondria respond to stressors, and how genetic variation affecting mitochondrial function alters response to exposures are areas of rapid research growth. This Special Issue was created to highlight and review cutting-edge areas of research into chemical effects on mitochondrial function. We anticipate that it will stimulate additional research into the mechanisms by which chemical exposures impact mitochondria, the biological processes that protect mitochondria from such impacts, and the health consequences that result when defense and homeostatic mechanisms are overcome.

2003-03-01

Public opinion has been one factor affecting change in policies designed to reduce underage alcohol use. Extant research, however, has been criticized for using single survey items of unknown reliability to define adult attitudes on alcohol policy issues. The present investigation addresses a critical gap in the literature by deriving scales on public attitudes, knowledge, and concerns pertinent to alcohol policies designed to reduce underage drinking using a US probability sample survey of 7021 adults. Five attitudinal scales were derived from exploratory and confirmatory factor analyses addressing policies to: (1) regulate alcohol marketing, (2) regulate alcohol consumption in public places, (3) regulate alcohol distribution, (4) increase alcohol taxes, and (5) regulate youth access. The scales exhibited acceptable psychometric properties and were largely consistent with a rational framework which guided the survey construction.

Perspective: Challenges and Controversial Issues in the Dietary Guidelines for Americans, 1980-2015.

PubMed

Nestle, Marion

2018-03-01

Since 1980, every edition of the Dietary Guidelines for Americans (DGAs) has recommended increased consumption of fruits, vegetables, and whole grains, but reduced consumption of saturated fat, sugars, and sodium and, therefore, their primary food sources. Every edition has generated controversy, mainly from producers of foods affected by "eat less" recommendations, particularly meat. Objections to the 2015 DGAs focused on environmental as well as scientific issues, but also on purported conflicts of interest among members of the Dietary Guidelines Advisory Committee. On this basis, critics induced Congress to authorize the National Academy of Medicine (NAM) to review the process of drawing up the guidelines. The NAM's 2017 reports should strengthen the process, but as long as science continues to support advice to reduce consumption of targeted foods, the guidelines will continue to elicit political controversy.

Women in war: operational issues of menstruation and unintended pregnancy.

Christopher, Leslie A; Miller, Leslie

2007-01-01

With rapid and frequent deployments around the world, the current high level of military operations demands combat readiness of every military member. In the U.S. Armed Forces, women represent 15% of active duty troops and 17% of reserve and Guard troops and are a critical component for mission accomplishment. The operational issues of menstruation and unintended pregnancy, unique to this population, can decrease a female member's military readiness and affect her ability to deploy. Strategies to mitigate and even eliminate these concerns include the optional use of hormonal medications to induce reversible menstrual cycle suppression. These medications, traditionally indicated for contraception, should be considered essential for female troops during training and deployment. This article, tailored specifically for military women, provides valuable information regarding the risks and benefits, as well as the various options available for menstrual cycle suppression.

In Ethiopia, improvement and innovation of the emergency care system is hindered by lack of specialist doctors trained in emergency medicine, underdeveloped emergency care infrastructure, and resource limitations. Our aim was to examine the critical factors affecting retention of graduates from the Addis Ababa University (AAU) post-graduate emergency medicine (EM) training program within the Ethiopian health care system. One post-graduate trainee and one program manager from the AAU and the University of Toronto (UT) partnership conducted qualitative interviews with current AAU EM residents and stakeholders in Ethiopian EM. Qualitative inductive thematic analysis was performed. Resident and stakeholder participants identified critical factors in three domains: the individual condition, the occupational environment, and the national context. Within each domain, priority themes emerged from the responses, including the importance of career satisfaction over the career continuum (individual condition), the opportunity to be involved in the developing EM program and challenges associated with resource, economic, and employment constraints (occupational environment), and perceptions regarding the state of awareness of EM and the capacity for change at the societal level (national context). This work underscores the need to continue to address multiple systemic and cultural issues within the Ethiopian health care landscape in order to address EM graduate retention. It also highlights the potential success of a retention strategy focused on the career ambitions of keen EM doctors.

It is uncertain whether the duration of red-cell storage affects mortality after transfusion among critically ill adults. In an international, multicenter, randomized, double-blind trial, we assigned critically ill adults to receive either the freshest available, compatible, allogeneic red cells (short-term storage group) or standard-issue (oldest available), compatible, allogeneic red cells (long-term storage group). The primary outcome was 90-day mortality. From November 2012 through December 2016, at 59 centers in five countries, 4994 patients underwent randomization and 4919 (98.5%) were included in the primary analysis. Among the 2457 patients in the short-term storage group, the mean storage duration was 11.8 days. Among the 2462 patients in the long-term storage group, the mean storage duration was 22.4 days. At 90 days, there were 610 deaths (24.8%) in the short-term storage group and 594 (24.1%) in the long-term storage group (absolute risk difference, 0.7 percentage points; 95% confidence interval [CI], -1.7 to 3.1; P=0.57). At 180 days, the absolute risk difference was 0.4 percentage points (95% CI, -2.1 to 3.0; P=0.75). Most of the prespecified secondary measures showed no significant between-group differences in outcome. The age of transfused red cells did not affect 90-day mortality among critically ill adults.

In recent years, an increment of infections caused by gram-positive cocci has been documented in nosocomial and hospital-acquired-infections. In diverse countries, a rapid development of resistance to common antibiotics against gram-positive cocci has been observed. This situation is exceptional in Spain but our country might be affected in the near future. New antimicrobials active against these multi-drug resistant pathogens are nowadays available. It is essential to improve our current knowledge about pharmacokinetic properties of traditional and new antimicrobials to maximize its effectiveness and to minimize toxicity. These issues are even more important in critically ill patients because inadequate empirical therapy is associated with therapeutic failure and a poor outcome. Experts representing two scientific societies (Grupo de estudio de Infecciones en el Paciente Crítico de la SEIMC and Grupo de trabajo de Enfermedades Infecciosas de la SEMICYUC) have elaborated a consensus document based on the current scientific evidence to summarize recommendations for the treatment of serious infections caused by gram-positive cocci in critically ill patients.

This article explores how the trends toward long-term community care affecting people with developmental disabilities developed. Appropriateness of care and quality of life issues are discussed. The article also reviews the development of long-term care for frail and disabled elderly people and explores the arguments for a continuum of care that have developed in this area. The authors conclude that future policies with respect to meeting long-term care needs for people with developmental disabilities must be addressed flexibly on an individual basis, related to individual needs, and must provide a continuum of care services.

Human reproductive issues in space

NASA Technical Reports Server (NTRS)

Santy, Patricia A.; Jennings, Richard T.

1992-01-01

A review of reproductive functioning in animal species studied during space flight demonstrated that most species were affected significantly by the absence of gravity and/or the presence of radiation. These two factors induced alterations in normal reproductive functioning independently of, as well as in combination with, each other. Based on animal models, several potential problem areas regarding human reproductive physiology and functioning in the space environment were identified. While there are no current space flight investigations, the animal studies suggest priorities for future research in human reproduction. Such studies will be critical for the successful colonization of the space frontier.

Tight glycemic control in the ICU - is the earth flat?

Tight glycemic control in the ICU has been shown to reduce mortality in some but not all prospective randomized control trials. Confounding the interpretation of these studies are differences in how the control was achieved and underlying incidence of hypoglycemia, which can be expected to be affected by the introduction of continuous glucose monitoring (CGM). In this issue of Critical Care, a consensus panel provides a list of the research priorities they believe are needed for CGM to become routine practice in the ICU. We reflect on these recommendations and consider the implications for using CGM today.

Three decades into the HIV pandemic, the issues affecting people with disabilities remain less known. Increasing attention has been given to this overlooked population when it comes to HIV prevention, treatment and care. This is related to the significant unmet sexual and reproductive healthcare needs facing people with disabilities worldwide. This article discusses the barriers to sexual health for people with disabilities in Africa and presents an argument about how mainstream HIV prevention work and research do not adequately attend to the sorts of systemic barriers that exclude people with disabilities, which a more targeted and critical approach could.

The epidemiology of vector-borne pathogens is determined by mechanisms and interactions at different scales of biological organization, from individual-level cellular processes to community interactions between species and with the environment. Most research, however, focuses on one scale or level with little integration between scales or levels within scales. Understanding the interactions between levels and how they influence our perception of vector-borne pathogens is critical. Here two examples of biological scales (pathogen transmission and mosquito mortality) are presented to illustrate some of the issues of scale and to explore how processes on different levels may interact to influence mosquito-borne pathogen transmission cycles. Individual variation in survival, vector competence, and other traits affect population abundance, transmission potential, and community structure. Community structure affects interactions between individuals such as competition and predation, and thus influences the individual-level dynamics and transmission potential. Modeling is a valuable tool to assess interactions between scales and how processes at different levels can affect transmission dynamics. We expand an existing model to illustrate the types of studies needed, showing that individual-level variation in viral dose acquired or needed for infection can influence the number of infectious vectors. It is critical that interactions within and among biological scales and levels of biological organization are understood for greater understanding of pathogen transmission with the ultimate goal of improving control of vector-borne pathogens.

Critical factors of implementing Industrialised Building System in Sarawak: A research on SMEs

Hadi, N. A.; Muhamad, W. M. N. W.; Othman, M. K. F.

2017-05-01

Industrialised Building System (IBS) have been adopted in Malaysia for over five decades and is expected to grow consistent with Malaysia's economic development. In promoting the adoption of IBS in construction projects, the government has taken several steps such as levy exemption for contractors and developers. Despite its numerous advantages and efforts pulled by the government, the implementation and adoption of IBS are still below the expected figure. Many researchers investigated readiness, setbacks and issues related to the implementation of IBS in Malaysia's construction projects. However, most of the research mainly for projects located in urban areas of West Malaysia. Therefore, this paper aims to close the gap on factors affecting the implementation of IBS for SMEs in Sarawak, where the level urbanisation is low. A semi-structured interview was conducted with 10 SME's contractors to get better insight view. The study found that logistics and infrastructure problems, a limited number of the manufacturer, lack of incentive, conventional payment methods, lack of financial supports are among critical factors affecting the implementation of IBS. Therefore, it was concluded that government plays major role in providing supports, incentives and facilitating the improvement of infrastructure to successfully implementing IBS in Sarawak.

Africa continues to bear a disproportionate share of the global HIV/AIDS, tuberculosis (TB) and malaria burden. The development and distribution of safe, effective and affordable vaccines is critical to reduce these epidemics. However, conducting HIV/AIDS, TB, and/or malaria vaccine trials simultaneously in developing countries, or in populations affected by all three diseases, is likely to result in numerous ethical challenges. In order to explore convergent ethical issues in HIV/AIDS, TB and malaria vaccine trials in Africa, the Ethics, Law and Human Rights Collaborating Centre of the WHO/UNAIDS African AIDS Vaccine Programme hosted a consultation on the Convergent Ethical Issues in HIV/AIDS, TB and Malaria Vaccine Trials in Africa in Durban, South Africa on the 10-11 February 2009. Key cross cutting ethical issues were prioritized during the consultation as community engagement; ancillary care obligations; care and treatment; informed consent; and resource sharing. The consultation revealed that while there have been few attempts to find convergence on ethical issues between HIV/AIDS, TB and malaria vaccine trial fields to date, there is much common ground and scope for convergence work between stakeholders in the three fields.

Imperceptible watermarking for security of fundus images in tele-ophthalmology applications and computer-aided diagnosis of retina diseases.

The authentication and integrity verification of medical images is a critical and growing issue for patients in e-health services. Accurate identification of medical images and patient verification is an essential requirement to prevent error in medical diagnosis. The proposed work presents an imperceptible watermarking system to address the security issue of medical fundus images for tele-ophthalmology applications and computer aided automated diagnosis of retinal diseases. In the proposed work, patient identity is embedded in fundus image in singular value decomposition domain with adaptive quantization parameter to maintain perceptual transparency for variety of fundus images like healthy fundus or disease affected image. In the proposed method insertion of watermark in fundus image does not affect the automatic image processing diagnosis of retinal objects & pathologies which ensure uncompromised computer-based diagnosis associated with fundus image. Patient ID is correctly recovered from watermarked fundus image for integrity verification of fundus image at the diagnosis centre. The proposed watermarking system is tested in a comprehensive database of fundus images and results are convincing. results indicate that proposed watermarking method is imperceptible and it does not affect computer vision based automated diagnosis of retinal diseases. Correct recovery of patient ID from watermarked fundus image makes the proposed watermarking system applicable for authentication of fundus images for computer aided diagnosis and Tele-ophthalmology applications.

The sustainability of ecosystem services depends on a firm understanding of both how organisms provide these services to humans and how these organisms will be altered with a changing climate. Unquestionably a dominant feature of most ecosystems, invertebrates affect many ecosystem services and are also highly responsive to climate change. However, there is still a basic lack of understanding of the direct and indirect paths by which invertebrates influence ecosystem services, as well as how climate change will affect those ecosystem services by altering invertebrate populations. This indicates a lack of communication and collaboration among scientists researching ecosystem services and climate change effects on invertebrates, and land managers and researchers from other disciplines, which becomes obvious when systematically reviewing the literature relevant to invertebrates, ecosystem services, and climate change. To address this issue, we review how invertebrates respond to climate change. We then review how invertebrates both positively and negatively influence ecosystem services. Lastly, we provide some critical future directions for research needs, and suggest ways in which managers, scientists and other researchers may collaborate to tackle the complex issue of sustaining invertebrate-mediated services under a changing climate. © 2012 The Authors.

Buelow, Melissa T; Suhr, Julie A

2009-03-01

The Iowa Gambling Task (IGT) was created to assess real-world decision making in a laboratory setting and has been applied to various clinical populations (i.e., substance abuse, schizophrenia, pathological gamblers) outside those with orbitofrontal cortex damage, for whom it was originally developed. The current review provides a critical examination of lesion, functional neuroimaging, developmental, and clinical studies in order to examine the construct validity of the IGT. The preponderance of evidence provides support for the use of the IGT to detect decision making deficits in clinical populations, in the context of a more comprehensive evaluation. The review includes a discussion of three critical issues affecting the validity of the IGT, as it has recently become available as a clinical instrument: the lack of a concise definition as to what aspect of decision making the IGT measures, the lack of data regarding reliability of the IGT, and the influence of personality and state mood on IGT performance.

The struggle of giving up personal goals: affective, physiological, and cognitive consequences of an action crisis.

PubMed

Brandstätter, Veronika; Herrmann, Marcel; Schüler, Julia

2013-12-01

A critical phase in goal striving occurs when setbacks accumulate and goal disengagement becomes an issue. This critical phase is conceptualized as an action crisis and assumed to be characterized by an intrapsychic conflict in which the individual becomes torn between further goal pursuit and goal disengagement. Our theorizing converges with Klinger's conceptualization of goal disengagement as a process, rather than a discrete event. Two longitudinal field studies tested and found support for the hypothesis that an action crisis not only compromises an individual's psychological and physiological well-being, but also dampens the cognitive evaluation of the respective goal. In Study 3, marathon runners experiencing an action crisis in their goal of running marathons showed a stronger cortisol secretion and a lower performance in the race 2 weeks later. Results are interpreted in terms of action-phase-specific mindsets with a focus on self-regulatory processes in goal disengagement.

Improved Management of Water and Natural Resources Requires Open, Cognizant, Adaptive Science and Policy

Water issues impact the availability and use of other natural resources as well as environmental conditions. In an increasingly populated hyper-connected world, water issues are increasingly "wicked problems": complex problems with high uncertainties and no independent observers. Water is essential to life, and life affects water quality and availability. Scientists, managers, decision-makers, and the greater public all have a stake in improving the management of water resources. In turn, they are part of the systems that they are studying, deciding on, affecting, or trying to improve. Governance of water issues requires greater accessibility, traceability, and accountability (ATA) in science and policy. Water-related studies and decision-making need transdisciplinary science, inclusive participatory processes, and consideration and acceptance of multiple perspectives. Biases, Beliefs, Heuristics, and Values (BBHV) shape much of our perceptions and knowledge, and inevitably, affect both science and policy. Understanding the role of BBHV is critical to (1) understanding individual and group judgments and choices, (2) recognizing potential differences between societal "wants" and societal "needs", and (3) identifying "winners" and "losers" of policy decisions. Societal acceptance of proposed policies and actions can be fostered by enhancing participatory processes and by providing greater ATA in science, in policy, and in development of the laws, rules, and traditions that constrain decision-making. An adaptive science-infused governance framework is proposed that seeks greater cognizance of the role of BBHV in shaping science and policy choices and decisions, and that also seeks "Open Traceable Accountable Policy" to complement "Open Science". We discuss the limitations of the governance that we suggest, as well as tools and approaches to help implementation.

Forest management activities can have substantial effects on forest structure and community composition and response of wildlife therein. Bats can be highly influenced by these structural changes, and understanding how forest management affects day-roost and foraging ecology of bats is currently a paramount conservation issue. With populations of many cave-hibernating bat species in eastern North America declining as a result of white-nose syndrome (WNS), it is increasingly critical to understand relationships among bats and forest-management activities. Herein, we provide a comprehensive literature review and synthesis of: (1) responses of northern long-eared (Myotis septentrionalis) and tri-colored (Perimyotis subflavus) bats—two species affected by WNS that use forests during summer—to forest management, and (2) an update to a previous review on the ecology of the endangered Indiana bat (Myotis sodalis).

A Review of Consequences of Poverty on Economic Decision-Making: A Hypothesized Model of a Cognitive Mechanism

Adamkovič, Matúš; Martončik, Marcel

2017-01-01

This review focuses on the issue of poverty affecting economic decision-making. By critically evaluating existing studies, the authors propose a structural model detailing the cognitive mechanism involved in how poverty negatively impacts economic decision-making, and explores evidence supporting the basis for the formation of this model. The suggested mechanism consists of a relationship between poverty and four other factors: (1) cognitive load (e.g., experiencing negative affect and stress); (2) executive functions (e.g., attention, working memory, and self-control); (3) intuition/deliberation in decision-making; and (4) economic decision-making (e.g., time-discounting and risk preference), with a final addition of financial literacy as a covariate. This paper focuses on shortfalls in published research, and delves further into the proposed model. PMID:29075221

Preliminary Investigation of the Sources of Self-Efficacy Among Teachers of Students with Autism

Teacher self-efficacy refers to the beliefs teachers hold regarding their capability to bring about desired instructional outcomes and may be helpful for understanding and addressing critical issues such as teacher attrition and teacher use of research-supported practices. Educating students with autism likely presents teachers with some of the most significant instructional challenges. The self-efficacy of 35 special education teachers of students with autism between the ages of 3 to 9 years was evaluated. Teachers completed rating scales that represented self-efficacy and aspects of the following 3 of Bandura’s 4 sources of self-efficacy: (1) sense of mastery, (2) social persuasions, and (3) physiological/affective states. Significant associations were observed between physiological/affective states and self-efficacy, but no associations were observed for the other sources. PMID:21691453

The purpose of this paper is to provide background to this special issue and consider how critically oriented research can be applied to health and social care management. Basic principles of critical management studies are introduced briefly to frame subsequent papers in this issue. In order to identify the wicked problems and darker sides of the care field, there is a need to study things in alternative ways through critical lenses. Giving a voice to those in less powerful positions may result in redefinition and redesign of conventional roles and agency of patients, volunteers and professionals and call into question the taken-for-granted understanding of health and social care management. The special issue as a whole was designed to enhance critical approaches to the discussion in the field of health and social care. This editorial hopefully raises awareness of CMS and serves as an opening for further discussion on critical views in the research on management and organization in this field.

The differing perspectives of workers and occupational medicine physicians on the ethical, legal and social issues of genetic testing in the workplace.

2011-01-01

Genetic testing in the workplace holds the promise of improving worker health but also raises ethical, legal, and social issues. In considering such testing, it is critical to understand the perspectives of workers, who are most directly affected by it, and occupational health professionals, who are often directly involved in its implementation. Therefore, a series of focus groups of unionized workers (n=25) and occupational medicine physicians (n=23) was conducted. The results demonstrated strikingly different perspectives of workers and physicians in several key areas, including the goals and appropriateness of genetic testing, and methods to minimize its risks. In general, workers were guided by a profound mistrust of the employer, physician, and government, while physicians were guided primarily by scientific and medical concerns, and, in many cases, by the business concerns distrusted by the workers.

Introduction--the Socially Sustainable Egg Production project.

PubMed

Swanson, J C; Mench, J A; Thompson, P B

2011-01-01

The social and political pressure to change egg production from conventional cage systems to alternative systems has been largely driven by the desire to provide more behavioral freedom for egg-laying hens. However, a change of this magnitude can affect other components of the production system and may result in unintended outcomes. To understand this issue, a Socially Sustainable Egg Production project was formed to 1) conduct a holistic and integrated systematic review of the current state of knowledge about various aspects of sustainable egg production, and 2) develop a coordinated grant proposal for future extramural funding based on the research priorities identified from the review. Expert study groups were formed to write evidence-based papers in 5 critical sustainability areas: hen health and welfare, economics, food safety and quality, public attitudes, and environmental impacts. These papers were presented as the PSA Emerging Issues Symposium on Social Sustainability of Egg Production at the 2010 Poultry Science Association meeting.

Putting the value into biosimilar decision making: the judgment value criteria.

Uncertainties remain the key issue surrounding biosimilars, although decisions regarding their use must be made. The challenges for policymakers, doctors, patients and others seeking to navigate in the uncharted waters of biosimilars must be clarified. At the most basic level, scientific understanding of the issue remains limited and when making decisions, policymakers must consider all those affected by health policy decisions, particularly the ultimate recipients of these medicines: the patients. The biosimilar-value chain relies on measurement of comparabilities. The goal is to demonstrate how, from a molecular perspective, closely similar they are or are not and how potential small differences may be relevant to clinical outcomes. To critically understand these points, this conceptual paper will present a knowledge-value chain and discuss each dimension assigning value in the decision making process re-utilization of biosimilars.

Critical theory as an approach to the ethics of information security.

PubMed

Stahl, Bernd Carsten; Doherty, Neil F; Shaw, Mark; Janicke, Helge

2014-09-01

Information security can be of high moral value. It can equally be used for immoral purposes and have undesirable consequences. In this paper we suggest that critical theory can facilitate a better understanding of possible ethical issues and can provide support when finding ways of addressing them. The paper argues that critical theory has intrinsic links to ethics and that it is possible to identify concepts frequently used in critical theory to pinpoint ethical concerns. Using the example of UK electronic medical records the paper demonstrates that a critical lens can highlight issues that traditional ethical theories tend to overlook. These are often linked to collective issues such as social and organisational structures, which philosophical ethics with its typical focus on the individual does not tend to emphasise. The paper suggests that this insight can help in developing ways of researching and innovating responsibly in the area of information security.

[Presentation of the "physical handicap" topic in six selected children's books--a critical analysis].

PubMed

Flottmeyer, L; Fries, A

1993-05-01

Since the late 60s, reality-oriented books for children and young people have increasingly turned to subject-matters and issues involving social/societal criticism, among them the theme of "being disabled". In the discussion on the degree to which media, and books in particular, do affect children's attitudes and socialization, it has been underlined that media take effect in the development of specific attitudinal patterns and behavioural dispositions in those cases where the recipient has not already formed a "completed" opinion of the topic at hand. This in particular is true in children of primary school age, and above all relates to their view of the disabled person. Six selected children's books were reviewed critically, based on a catalogue of criteria permitting coverage of as wide as spectrum as possible of "physical disability" and allied subjects. Summarizing, it is noted that the books reviewed do give children the opportunity, and partly in an excellent manner, of gaining insights into the situation of disabled persons. The potential for didactical treatment in primary classrooms is pointed out.

Factors of accepting pain management decision support systems by nurse anesthetists

PubMed Central

2013-01-01

Background Pain management is a critical but complex issue for the relief of acute pain, particularly for postoperative pain and severe pain in cancer patients. It also plays important roles in promoting quality of care. The introduction of pain management decision support systems (PM-DSS) is considered a potential solution for addressing the complex problems encountered in pain management. This study aims to investigate factors affecting acceptance of PM-DSS from a nurse anesthetist perspective. Methods A questionnaire survey was conducted to collect data from nurse anesthetists in a case hospital. A total of 113 questionnaires were distributed, and 101 complete copies were returned, indicating a valid response rate of 89.3%. Collected data were analyzed by structure equation modeling using the partial least square tool. Results The results show that perceived information quality (γ=.451, p<.001), computer self-efficacy (γ=.315, p<.01), and organizational structure (γ=.210, p<.05), both significantly impact nurse anesthetists’ perceived usefulness of PM-DSS. Information quality (γ=.267, p<.05) significantly impacts nurse anesthetists’ perceptions of PM-DSS ease of use. Furthermore, both perceived ease of use (β=.436, p<.001, R2=.487) and perceived usefulness (β=.443, p<.001, R2=.646) significantly affected nurse anesthetists’ PM-DSS acceptance (R2=.640). Thus, the critical role of information quality in the development of clinical decision support system is demonstrated. Conclusions The findings of this study enable hospital managers to understand the important considerations for nurse anesthetists in accepting PM-DSS, particularly for the issues related to the improvement of information quality, perceived usefulness and perceived ease of use of the system. In addition, the results also provide useful suggestions for designers and implementers of PM-DSS in improving system development. PMID:23360305

Childhood obesity continues to be a critical healthcare issue and a paradigm of a pervasive chronic disease affecting even our youngest children. When considered within the context of the socioecological model, the factors that influence weight status, including the social determinants of health, limit the impact of multidisciplinary care that occurs solely within the medical setting. Coordinated care that incorporates communication between the healthcare and community sectors is necessary to more effectively prevent and treat obesity. In this article, the Expert Exchange authors, with input from providers convened at an international pediatric meeting, provide recommendations to address this critical issue. These recommendations draw upon examples from the management of other chronic conditions that might be applied to the treatment of obesity, such as the use of care plans and health assessment forms to allow weight management specialists and community personnel (e.g., school counselors) to communicate about treatment recommendations and responses. To facilitate communication across the healthcare and community sectors, practical considerations regarding the development and/or evaluation of communication tools are presented. In addition, the use of technology to enhance healthcare-community communication is explored as a means to decrease the barriers to collaboration and to create a web of connection between the community and healthcare providers that promote wellness and a healthy weight status.

Hybrid Approach for Automatic Evaluation of Emotion Elicitation Oriented to People with Intellectual Disabilities

NASA Astrophysics Data System (ADS)

Martínez, R.; de Ipiña, K. López; Irigoyen, E.; Asla, N.

People with intellectual disabilities and elderly need physical and intellectual support to ensuring independent living. This is one of the main issues in applying Information and Communication Technology (ICT) into Assistive Technology field. In this sense the development of appropriated Intelligent Systems (ISs) offers new perspectives to this community. In our project a new IS system (LAGUNTXO) which adds user affective information oriented to people with intellectual disabilities has been developed. The system integrates a Human Emotion Analysis System (HEAS) which attempts to solve critical situations for this community as block stages. In the development of the HEAS one of the critical issues was to create appropriated databases to train the system due to the difficulty to simulate pre-block stages in laboratory. Finally a films and real sequences based emotion elicitation database was created. The elicitation material was categorized with more actual features based on discrete emotions and dimensional terms (pleasant, unpleasant). Classically the evaluation is carried out by a specialist (psychologist). In this work we present a hybrid approach for Automatic Evaluation of Emotion Elicitation databases based on Machine Learning classifiers and K-means clustering. The new categorization and the automatic evaluation show a high level of accuracy with respect to others methodologies presented in the literature.

Human behavioral research in space: quandaries for research subjects and researchers

NASA Technical Reports Server (NTRS)

Shepanek, Marc

2005-01-01

With the advent of long-duration spaceflight on board the International Space Station (ISS) and possible future missions beyond low Earth orbit (LEO) such as Mars, it is critical that those at NASA have a realistic assessment of the challenges that will face individuals on long-duration missions so that they can develop preventive and real-time countermeasures to behavioral health issues. While space travellers are very interested in having countermeasures to the deleterious effects of space missions, they have a powerful disincentive to participate in this research if they feel it could in any way negatively affect their flight status. The behavioral issues of isolation and confinement for extended-duration space missions are reviewed. Areas of basic and clinical behavioral research are listed. And the classical clinical model for research is not considered appropriate for the current configuration of the space program. The use of analogue environments and advanced statistical analysis are suggested as ways to address the limited spaceflight research opportunities. The challenge of research subject or patient confidentiality vs. mission safety and issues of personal flight status are addressed.

At issue: The future of cognitive rehabilitation of schizophrenia.

PubMed

Silverstein, Steven M; Wilkniss, Sandra M

2004-01-01

Cognitive rehabilitation is becoming an increasingly popular intervention in treatment programs for people with schizophrenia. Despite this increased acceptance, however, the evidence base on its effectiveness is not impressive. Moreover, given the evidence of cognitive recovery in treated patients who do not receive cognitive rehabilitation--from newer medications and from other evidence-based psychosocial interventions--it is not clear whether cognitive rehabilitation is worth its expense in time and resources. We believe that the slow progress in the field of cognitive rehabilitation of schizophrenia is related to failure to address several critical issues: (1) the importance of manipulating stimulus and context structure in rehabilitative interventions; (2) the need to base a cognitive rehabilitation of schizophrenia on cognitive neuroscience as opposed to neuropsychology; (3) the importance of systematically addressing motivation, self-esteem, and affective factors when designing cognition-enhancing interventions; (4) the need to move beyond one-size-fits-all interventions and develop individualized treatments; and (5) the need to address abnormalities in the experience of the self when designing interventions to optimize cognitive and behavioral performance. Suggestions for addressing these issues are discussed.

Supporting mental health in South African HIV-affected communities: primary health care professionals’ understandings and responses

PubMed Central

Burgess, Rochelle Ann

2015-01-01

How do practitioners respond to the mental distress of HIV-affected women and communities? And do their understandings of patients’ distress matter? The World Health Organization (WHO) along with advocates from the Movement for Global Mental Health (MGMH) champion a primary mental health care model to address burgeoning mental health needs in resource-poor HIV-affected settings. Whilst a minority of studies have begun to explore interventions to target this group of women, there is a dearth of studies that explore the broader contexts that will likely shape service outcomes, such as health sector dynamics and competing definitions of mental ill-health. This study reports on an in-depth case study of primary mental health services in a rural HIV-affected community in Northern KwaZulu-Natal. Health professionals identified as the frontline staff working within the primary mental health care model (n = 14) were interviewed. Grounded thematic analysis of interview data highlighted that practitioners employed a critical and socially anchored framework for understanding their patients’ needs. Poverty, gender and family relationships were identified as intersecting factors driving HIV-affected patients’ mental distress. In a divergence from existing evidence, practitioner efforts to act on their understandings of patient needs prioritized social responses over biomedical ones. To achieve this whilst working within a primary mental health care model, practitioners employed a series of modifications to services to increase their ability to target the sociostructural realities facing HIV-affected women with mental health issues. This article suggests that beyond attention to the crucial issues of funding and human resources that face primary mental health care, attention must also be paid to promoting the development of policies that provide practitioners with increased and more consistent opportunities to address the complex social realities that frame the mental distress of HIV-affected women.

Nutrition in Space: Benefits on Earth

NASA Technical Reports Server (NTRS)

Smith, Scott M.

2006-01-01

History has often proven the criticality for adequate nutrition to ensure expedition success. Space exploration will be no different, with the exception of the certainty that food will not be found along the journey. Ensuring the health and safety of astronauts is critical and nutrition will serve several functions to that end. Nutritional assessment of International Space Station (ISS) crewmembers not only serves to evaluate the nutritional health of individuals, but also allows a better understanding of how space flight affects nutritional requirements, and how nutrition can serve in mitigating the negative effects of weightlessness on the human. Available data suggest that the nutritional status of astronauts is compromised during and after flight. Inadequate dietary intake and subsequent weight loss are often considered hallmarks of space flight, although exceptions to this do exist, and provide hope. However, beyond energy intake, specific nutrient issues also exist. Several vitamins, including D and folate, are affected in space travelers. Hematological and antioxidant defense systems are impacted, with increased iron storage, and increased markers of oxidative damage. Bone loss during space flight remains a critical challenge. Ground-based studies have proven that nutrition is a potent modulator of the bone response to simulated weightlessness. Protein and sodium are two nutrients which tend to exacerbate bone resorption and loss, likely mediated through acid base balance. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health. Both flight and ground-based research provide a unique situation, one where healthy individuals are put in a unique and challenging environment. A full understanding of the role of nutrition during space flight will not only enhance crew health and safety during flight, but will also expand our understanding of the role of nutrition in health of those remaining on Earth.

Peng, Tai-Quan; Sun, Guodao; Wu, Yingcai

2017-01-01

This study aims to elucidate the intricate interplay between public attention and public emotion toward multiple social issues. A theoretical framework is developed based on three perspectives including endogenous affect hypothesis, affect transfer hypothesis, and affective intelligence theory. Large-scale longitudinal data with 265 million tweets on five social issues are analyzed using a time series analytical approach. Public attention on social issues can influence public emotion on the issue per se. Social issues interact with one another to attract public attention in both cooperative and competitive ways. Instead of a direct transfer from public emotion to public attention, the public emotion toward a social issue moderates the interaction between the issue and other issue(s). PMID:28081117

Lerman, S F; Shahar, G; Rudich, Z

2012-01-01

This longitudinal study examined the role of the trait of self-criticism as a moderator of the relationship between the affective and sensory components of pain, and depression. One hundred and sixty-three chronic pain patients treated at a specialty pain clinic completed self-report questionnaires at two time points assessing affective and sensory components of pain, depression, and self-criticism. Hierarchical linear regression analysis revealed a significant 3-way interaction between self-criticism, affective pain and gender, whereby women with high affective pain and high self-criticism demonstrated elevated levels of depression. Our findings are the first to show within a broad, comprehensive model, that selfcriticism is activated by the affective, but not sensory component of pain in leading to depressive symptoms, and highlight the need to assess patients' personality as part of an effective treatment plan. © 2011 European Federation of International Association for the Study of Pain Chapters.

Critical Factors for Successful Practice of Disaster-Resilient Community in Urban City

Chou, J. S.; Wu, J. H.

2017-12-01

Due to special geographical environment, Taiwan is a natural disaster-prone area, which often suffers from earthquakes, typhoons and other natural hazards, resulting in heavy casualties and huge property losses. Furthermore, effect of global warming increases extreme climate events and leads to frequent and severe natural disasters. Therefore, disaster prevention and response are not only an important issue of government policy, but also a critical issue of people's life. Rather than over-reliance on government assistance, the spontaneous participation and co-operation by people can complete specific disaster preparedness and reinforce local energy of disaster prevention and response. Although the concept of disaster-resilient community (DRC) has been shaped for a period of time, residents in the community cannot keep up the pace with government, which may decrease the effectiveness of DRC development. Thus, the study of theory and practice of urban DRC becomes an imperative need. This article is a qualitative case study, which uses the participant observation and self-reflection in action research methods to collect relevant information for empirical validation. Particularly, this investigation is supplemented by service work experience in DRC promotion conducted by the researchers. According to the qualitative analyses of case communities during training process of disaster prevention and preparedness, we can identify the critical factors affecting the level of community-based disaster prevention and protection works. Based on the literature and empirical supports, the factors are discussed through three spindle constructs respectively, namely coping strategy, operations management and organizational behavior. Based on the findings of this study, we make conclusions and suggestions for related authority in sustainably promoting DRC.

Occupational risk factors in inflammatory bowel disease.

Leso, V; Ricciardi, W; Iavicoli, I

2015-08-01

Crohn's disease and ulcerative colitis are the two main forms of inflammatory bowel disease (IBD). Although the aetiology of IBD is not completely understood, an interaction between genetic and environmental factors has been proposed. In this context, however, environmental epidemiology lacks a comprehensive evaluation of the possible role of occupational exposures in IBD development and progression. Therefore, aim of our review was to evaluate how certain occupational risk factors may affect IBD pathogenesis, clinical history and severity of disease manifestations. A critical revision of available literature concerning exposure to groups of potential workplace hazardous agents and IBD, as it appears in Medline and Web of knowledge, was performed. The role of workplace exposures to chemical and biological agents, ionizing or non-ionizing radiations, shift-works, indoor, and sedentary works as well as job strain on IBD has been critically revised. However, the limited number of studies addressing these issues prevented us from extrapolating definite conclusions. Our review pointed out some critical aspects concerning the relationship between occupational factors and IBD, in terms of causative pathways, hazardous exposure, susceptibility and consequences of IBD functional limitations on career choice and fitness for work that need future investigations. Overall, this seems a challenging public health issue, considering the strong IBD impact on patients' quality of life, work productivity and costs to society. Moreover, this review may encourage concerted actions of health care specialists, occupational physicians, employers and IBD workers to plan preventive and protective measures for "healthier patterns of work" for IBD and to develop innovative perspectives for an integrated management of "IBD at work".

2014-01-01

Although advancements in the field of inflammatory bowel disease (IBD) include effective therapies for many patients with Crohn’s disease and ulcerative colitis, there remains a large unmet need, and there is a large number of investigational agents in the pipeline. Drug development through clinical trials is critical to understanding the safety and efficacy of new therapies in the affected human population, and the need for ethical trial design is of the utmost importance. This paper explores the ethical issues of clinical trials in IBD, focusing on placebo-controlled trials, vulnerable patients, exposure to monoclonal antibodies, globalization of trials, and surgical advances.

The emergence of bacteria resistance to most of the currently available antibiotics has become a critical therapeutic problem. The bacteria causing both hospital and community-acquired infections are most often multidrug resistant. In view of the alarming level of antibiotic resistance between bacterial species and difficulties with treatment, alternative or supportive antibacterial cure has to be developed. The presented review focuses on the major characteristics of bacteriophages and phage-encoded proteins affecting their usefulness as antimicrobial agents. We discuss several issues such as mode of action, pharmacodynamics, pharmacokinetics, resistance and manufacturing aspects of bacteriophages and phage-encoded proteins application. PMID:23305359

Clinical approach to Parkinson's disease: features, diagnosis, and principles of management.

Parkinson's disease (PD) is one of the most common neurodegenerative disorders. The condition causes a heavy burden both on those affected, as well as their families. Accurate diagnosis is critical and remains founded on clinical grounds as no specific diagnostic test is available so far. The clinical picture of PD is typical in many instances; however, features distinguishing it from other disorders should be thoroughly sought. Monogenic forms of PD also have some distinctive characteristics in many cases. This text is a roadmap to accurate diagnosis in PD, as it approaches clinical features, diagnostic methodology, and leading differential diagnoses. Therapeutic issues are also briefly discussed.

Virtue theory and abortion.

Hursthouse, Rosalind

The sort of ethical theory derived from Aristotle, variously described as virtue ethics, virtue-based ethics, or neo-Aristotelianism, is becoming better known, and is now quite widely recognized as at least a possible rival to deontological and utilitarian theories. With recognition has come criticism, of varying quality. In this article I shall discuss nine separate criticisms that I have frequently encountered, most of which seem to me to betray an inadequate grasp either of the structure of virtue theory or of what would be involved in thinking about a real moral issue in its terms. In the first half I aim particularly to secure an understanding that will reveal that many of these criticisms are simply misplaced, and to articulate what I take to be the major criticism of virtue theory. I reject this criticism, but do not claim that it is necessarily misplaced. In the second half I aim to deepen that understanding and highlight the issues raised by the criticisms by illustrating what the theory looks like when it is applied to a particular issue, in this case, abortion.

Racial bias shapes social reinforcement learning.

Lindström, Björn; Selbing, Ida; Molapour, Tanaz; Olsson, Andreas

Both emotional facial expressions and markers of racial-group belonging are ubiquitous signals in social interaction, but little is known about how these signals together affect future behavior through learning. To address this issue, we investigated how emotional (threatening or friendly) in-group and out-group faces reinforced behavior in a reinforcement-learning task. We asked whether reinforcement learning would be modulated by intergroup attitudes (i.e., racial bias). The results showed that individual differences in racial bias critically modulated reinforcement learning. As predicted, racial bias was associated with more efficiently learned avoidance of threatening out-group individuals. We used computational modeling analysis to quantitatively delimit the underlying processes affected by social reinforcement. These analyses showed that racial bias modulates the rate at which exposure to threatening out-group individuals is transformed into future avoidance behavior. In concert, these results shed new light on the learning processes underlying social interaction with racial-in-group and out-group individuals.

Twenty-four hour, global aviation operations pose unique challenges to humans. Physiological requirements related to sleep, the internal circadian clock, and human fatigue are critical factors that are known to affect safety, performance, and productivity. Understanding the human operators' physiological capabilities, and limitations, will be important to address these issues as global demand for aviation activities continues to increase. In 1980, in response to a Congressional request, the National Aeronautics and Space Administration (NASA) Ames Research Center initiated a Fatigue/Jet Lag Program to examine the role of fatigue in flight operations. Originally established by Dr. John K. Lauber and Dr. Charles E. Billings, the Program was designed to address three objectives: (1) determine the extent of fatigue, sleep loss, and circadian disruption in flight operations; (2) determine how fatigue affected flight crew performance; and (3) develop strategies to maximize performance and alertness during flight operations.

Atmospheric aerosols are suspensions of liquid and solid particles that have diameters ranging from a few nanometers to several micrometers (μm). Atmospheric fine particulate matter (PM2.5, aerosols with aerodynamic diameters of 2.5 μm or less) are especially important since they can adversely affect air quality and human health as well as play a critical role in Earth's climate system. In terms of aerosol climate effects, PM2.5 can directly affect climate by scattering or absorbing incoming solar radiation or indirectly by acting as nuclei on which cloud droplets and ice particles form. As a result, a better understanding of processes that determine the formation and sinks of PM2.5 is needed for developing effective policies that improve air quality and public health as well as to accurately predict the response of the climate system due to changes in anthropogenic emissions.

Convergent ethical issues in HIV/AIDS, tuberculosis and malaria vaccine trials in Africa: Report from the WHO/UNAIDS African AIDS Vaccine Programme's Ethics, Law and Human Rights Collaborating Centre consultation, 10-11 February 2009, Durban, South Africa

PubMed Central

2010-01-01

Background Africa continues to bear a disproportionate share of the global HIV/AIDS, tuberculosis (TB) and malaria burden. The development and distribution of safe, effective and affordable vaccines is critical to reduce these epidemics. However, conducting HIV/AIDS, TB, and/or malaria vaccine trials simultaneously in developing countries, or in populations affected by all three diseases, is likely to result in numerous ethical challenges. Methods In order to explore convergent ethical issues in HIV/AIDS, TB and malaria vaccine trials in Africa, the Ethics, Law and Human Rights Collaborating Centre of the WHO/UNAIDS African AIDS Vaccine Programme hosted a consultation on the Convergent Ethical Issues in HIV/AIDS, TB and Malaria Vaccine Trials in Africa in Durban, South Africa on the 10-11 February 2009. Results Key cross cutting ethical issues were prioritized during the consultation as community engagement; ancillary care obligations; care and treatment; informed consent; and resource sharing. Conclusion The consultation revealed that while there have been few attempts to find convergence on ethical issues between HIV/AIDS, TB and malaria vaccine trial fields to date, there is much common ground and scope for convergence work between stakeholders in the three fields.

The potential impacts of migratory difficulty, including warmer waters and altered flow conditions, on the reproductive success of salmonid fishes

Fenkes, Miriam; Shiels, Holly A.; Fitzpatrick, John L.; Nudds, Robert L.

2016-01-01

Climate change and urbanisation of watercourses affect water temperatures and current flow velocities in river systems on a global scale. This represents a particularly critical issue for migratory fish species with complex life histories that use rivers to reproduce. Salmonids are migratory keystone species that provide substantial economical value to ecosystems and human societies. Consequently, a comprehensive understanding of the effects of environmental stressors on their reproductive success is critical in order to ensure their continued abundance during future climatic change. Salmonids are capital breeders, relying entirely on endogenous energy stores to fuel return migration to their natal spawning sites and reproduction upon arrival. Metabolic rates and cost of transport en-route increase with temperature and at extreme temperatures, swimming is increasingly fuelled anaerobically, resulting in an oxygen debt and reduced capacity to recover from exhaustive exercise. Thermally challenged salmonids also produce less viable gametes, which themselves are affected by water temperature after release. Passage through hydrological barriers and temperature changes both affect energy expenditure. As a result, important energetic tradeoffs emerge between extra energy used during migration and that available for other facets of the reproductive cycle, such as reproductive competition and gamete production. However, studies identifying these tradeoffs are extremely sparse. This review focuses on the specific locomotor responses of salmonids to thermal and hydrological challenges, identifying gaps in our knowledge and highlighting the potential implications for key aspects of their reproduction.

2018-03-01

The purpose of this study was to determine the effect of caring behaviours on critical thinking and to examine whether self-reflection mediates the effect of caring on critical thinking. We also tested whether caring behaviours moderated the relationship between self-reflection and critical thinking. For this descriptive, correlational, cross-sectional study, we recruited 293 fifth-year nursing students from a junior college in southern Taiwan. Data were collected in 2014 on critical thinking, caring behaviours and self-reflection with insight using the Taiwan Critical Thinking Disposition Inventory, a Chinese version of the Caring Assessment Report Evaluation Q-sort, and a Chinese version of the Self-Reflection and Insight Scale, respectively. Relationships among variables were analysed by structural equation modelling, with the partial least squares method and Sobel test. The results showed that caring behaviours significantly positively affected critical thinking (β = 0.56, t = 12.37, p < 0.001) and self-reflection with insight (β = 0.54, t = 11.99, p < 0.001). Self-reflection and insight significantly positively affected critical thinking (β = 0.34, t = 6.48, p < 0.001). Further, self-reflection and insight mediated the relationship between caring behaviours and critical thinking. Caring behaviours did not, however, moderate the relationship between self-reflection (β = 0.001, t = 0.021, p > 0.05) and critical thinking. Caring behaviours directly affect self-reflection with insight and critical thinking. In addition, caring behaviours also indirectly affect critical thinking through self-reflection and insight. © 2017 Nordic College of Caring Science.

This research aimed to investigate the changes in ethical issues in everyday clinical practice recognized by critical care nurses during two observation periods. We conducted a retrospective analysis of data obtained by prospective questionnaire surveys of nurses in the intensive care units (ICU) of a tertiary university-affiliated hospital in Seoul, Korea. Data were collected prospectively during two different periods, February 2002-January 2003 (Period 1) and August 2011-July 2012 (Period 2). Significantly fewer cases with ethical issues were reported in Period 2 than in Period 1 (89 cases [2.1%] of 4,291 ICU admissions vs. 51 [0.5%] of 9,302 ICU admissions, respectively; P < 0.001). The highest incidence of cases with identified ethical issues in both Periods occurred in MICU. The major source of ethical issues in Periods 1 and 2 was behavior-related. Among behaviorrelated issues, inappropriate healthcare professional behavior was predominant in both periods and mainly involved resident physicians. Ethical issue numbers regarding end-oflife (EOL) care significantly decreased in the proportion with respect to ethical issues during Period 2 (P = 0.044). In conclusion, the decreased incidence of cases with identified ethical issues in Period 2 might be associated with ethical enhancement related with EOL and improvements in the ICU care environment of the studied hospital. However, behaviorrelated issues involving resident physicians represent a considerable proportion of ethical issues encountered by critical care nurses. A systemic approach to solve behavior-related issues of resident physicians seems to be required to enhance an ethical environment in the studied ICU.

Meissner, C. W., Jr. (Editor); Dunham, J. R. (Editor); Crim, G. (Editor)

1989-01-01

The outcome is documented of a Flight-Critical Digital Systems Technology Workshop held at NASA-Langley December 13 to 15 1988. The purpose of the workshop was to elicit the aerospace industry's view of the issues which must be addressed for the practical realization of flight-critical digital systems. The workshop was divided into three parts: an overview session; three half-day meetings of seven working groups addressing aeronautical and space requirements, system design for validation, failure modes, system modeling, reliable software, and flight test; and a half-day summary of the research issues presented by the working group chairmen. Issues that generated the most consensus across the workshop were: (1) the lack of effective design and validation methods with support tools to enable engineering of highly-integrated, flight-critical digital systems, and (2) the lack of high quality laboratory and field data on system failures especially due to electromagnetic environment (EME).

Critical gases for critical issues: CO2 technologies for oral drug delivery.

PubMed

Danan, Hana; Esposito, Pierandrea

2014-02-01

In recent years, CO2-based technologies have gained considerable interest in the pharmaceutical industry for their potential applications in drug formulation and drug delivery. The exploitation of peculiar properties of gases under supercritical conditions has been studied in the last 20 years with mixed results. Promising drug-delivery technologies, based on supercritical CO2, have mostly failed when facing challenges of industrial scaleability and economical viability. Nevertheless, a 'second generation' of processes, based on CO2 around and below critical point has been developed, possibly offering technology-based solutions to some of the current issues of pharmaceutical development. In this review, we highlight the most recent advancements in this field, with a particular focus on the potential of CO2-based technologies in addressing critical issues in oral delivery, and briefly discuss the future perspectives of dense CO2-assisted processes as enabling technologies in drug delivery.

Coupled latent differential equation with moderators: simulation and application.

PubMed

Hu, Yueqin; Boker, Steve; Neale, Michael; Klump, Kelly L

2014-03-01

Latent differential equations (LDE) use differential equations to analyze time series data. Because of the recent development of this technique, some issues critical to running an LDE model remain. In this article, the authors provide solutions to some of these issues and recommend a step-by-step procedure demonstrated on a set of empirical data, which models the interaction between ovarian hormone cycles and emotional eating. Results indicated that emotional eating is self-regulated. For instance, when people do more emotional eating than normal, they will subsequently tend to decrease their emotional eating behavior. In addition, a sudden increase will produce a stronger tendency to decrease than will a slow increase. We also found that emotional eating is coupled with the cycle of the ovarian hormone estradiol, and the peak of emotional eating occurs after the peak of estradiol. The self-reported average level of negative affect moderates the frequency of eating regulation and the coupling strength between eating and estradiol. Thus, people with a higher average level of negative affect tend to fluctuate faster in emotional eating, and their eating behavior is more strongly coupled with the hormone estradiol. Permutation tests on these empirical data supported the reliability of using LDE models to detect self-regulation and a coupling effect between two regulatory behaviors.

Rayleigh-Taylor and Richtmyer-Meshkov Instabilities in Turbulent Regime

Dimonte, G.

1998-11-01

The Rayleigh-Taylor instability (RTI) and its shock driven analog, the Richtmyer-Meshkov instability (RMI), affect a wide variety of important phenomena from sub-terrainian to astrophysical environments. The ``fluids" are equally varied from plasmas and magnetic fields to elastic-plastic solids. In most applications, the instabilities occur with a complex acceleration history and evolve to a highly nonlinear state, making the theoretical description formidable. We will link the fluid and plasma regimes while describing the theoretical issues and basic experiments in different venues to isolate key physics issues. RMI experiments on the Nova laser investigate the affects of compressibility with strong radiatively driven shocks (Mach > 10) in near solid density plasmas of sub-millimeter scale. The growth of single sinusoidal and random 3-D perturbations are measured using backlit radiography. RTI experiments with the Linear Electric Motor (LEM) are conducted with a variety of acceleration (<< 10^4 m/s^2) histories and fluids of 10 cm scale. Turbulent RTI experiments with high Reynolds number liquids show self-similar growth which is characterized with laser induced fluorescence. LEM experiments with an elastic-plastic material (yogurt) exhibit a critical wavelength and amplitude for instability. The experimental results will be compared with linear and nonlinear theories and hydrodynamic simulations.

A critical issue in the design of the ITER low field side reflectometer is the transmission line (TL) system. A TL connects each launcher to a diagnostic instrument. Each TL will typically consist of ∼42 m of corrugated waveguide and up to ten miter bends. Important issues for the performance of the TL system are mode conversion and reflections. Minimizing these issues are critical to minimizing standing waves and phase errors. The performance of TL system is analyzed and recommendations are given.

A critical review of gender issues in understanding prolonged disability related to musculoskeletal pain: how are they relevant to rehabilitation?

PubMed

Côté, Daniel; Coutu, Marie-France

2010-01-01

The purpose of this critical review is to describe the available theoretical models for understanding the gender issues in prolonged work disability related to persistent musculoskeletal (MSK) pain. A critical literature review was conducted in medicine, health sciences, and social sciences databases (MEDLINE, CINHAL, PsychINFO and SOCINDEX) using specific keywords. After screening titles and abstracts, followed by methodological quality assessment, a total of 55 references were retained for content analysis. Gender issues in disability related to persistent MSK pain show that men and women may experience pain and rehabilitation process in different ways. Three main themes were exftracted and further described: (1) the experience of distrust; (2) the self-identity process; and (3) the domestic strain. Each of these themes has a specific and potentially different impact on men and women, and we report that experiential differences may strongly impact the rehabilitation process and outcomes such as return to work. This critical review provides insight into gender issues in the process of rehabilitation and outcomes such as return to work. We suggest that work and family considerations are the two most important issues in the rehabilitation process and that differences between men and women are likely to occur.

2014-01-01

Objectives: To explore factors which affect newly qualified doctors’ wellbeing and look at the implications for educational provision. Methods Data were collected by free association narrative interviews of nine Foundation doctors and analysed using a grounded theory approach. Two Foundation programme directors were interviewed to verify data validity. Results Two main themes emerged: newly qualified doctors’ wellbeing is affected by 1) personal experience and 2) work related factors. They start work feeling unprepared by medical school, work experience (“shadowing”) or induction programmes at the beginning of the post. Senior colleague support and feedback are much valued but often lacking with little discussion of critical incidents and difficult issues. Challenges include sick patients, prescribing, patient/relative communication and no consistent team structure. Working shift patterns affects personal and social life. Enjoyment and reward come from helping patients, feelings of making a difference or teaching medical students. Conclusions Whilst becoming familiar with their roles, newly qualified doctors search for identity and build up resilience. The support given during this process affects their wellbeing including coping with day to day challenges, whether posts are experienced as rewarding and how work influences their personal and social lives.

Context Evidence briefs have emerged as a promising approach to synthesizing the best available research evidence for health system policymakers and stakeholders. An evidence brief may draw on systematic reviews and many other types of policy-relevant information, including local data and studies, to describe a problem, options for addressing it, and key implementation considerations. We conducted a systematic review to examine the ways in which context- and issue-related factors influence the perceived usefulness of evidence briefs among their intended users. Methods We used a critical interpretive synthesis approach to review both empirical and nonempirical literature and to develop a model that explains how context and issues influence policymakers’ and stakeholders’ views of the utility of evidence briefs prepared for priority policy issues. We used a “compass” question to create a detailed search strategy and conducted electronic searches in CINAHL, EMBASE, HealthSTAR, IPSA, MEDLINE, OAIster (gray literature), ProQuest A&I Theses, ProQuest (Sociological Abstracts, Applied Social Sciences Index and Abstracts, Worldwide Political Science Abstracts, International Bibliography of Social Sciences, PAIS, Political Science), PsychInfo, Web of Science, and WilsonWeb (Social Science Abstracts). Finally, we used a grounded and interpretive analytic approach to synthesize the results. Findings Of the 4,461 papers retrieved, 3,908 were excluded and 553 were assessed for “relevance,” with 137 included in the initial sample of papers to be analyzed and an additional 23 purposively sampled to fill conceptual gaps. Several themes emerged: (1) many established types of “evidence” are viewed as useful content in an evidence brief, along with several promising formatting features; (2) contextual factors, particularly the institutions, interests, and values of a given context, can influence views of evidence briefs; (3) whether an issue is polarizing and whether it is salient (or not) and familiar (or not) to actors in the policy arena can influence views of evidence briefs prepared for that issue; (4) influential factors can emerge in several ways (as context driven, issue driven, or a result of issue-context resonance); (5) these factors work through two primary pathways, affecting either the users or the producers of briefs; and (6) these factors influence views of evidence briefs through a variety of mechanisms. Conclusions Those persons funding and preparing evidence briefs need to consider a variety of context- and issue-related factors when deciding how to make them most useful in policymaking.

The Power Behind the Controversy: Understanding Local Policy Elites' Perceptions on the Benefits and Risks Associated with High Voltage Power Line Installation in the State of Arkansas

NASA Astrophysics Data System (ADS)

Moyer, Rachael M.

Following a proposal for the installation of high voltage power lines in northwest Arkansas, a controversial policy debate emerged. Proponents of the transmission line argue that such an installation is inevitable and necessary to efficiently and reliably support the identified electric load in the region. Opponents claim that the lines will degrade the natural environment and hamper the tourism-based local economy in affected regions, notably in Ozark Mountain areas. This study seeks to understand how local policy elites perceive the benefits and risks associated with proposed transmission lines, which is a critical step in comprehending the formation and changes of related government policies. First, based upon the dual process theory of judgment, this study systematically investigates the triadic relationships between (a) more profound personal value predispositions, (b) affects and feelings, and (c) perceived benefits and risks related to the proposed installation of high voltage power lines among local policy elites in the state of Arkansas. Next, this study focuses more specifically on the role of value predispositions, specific emotional dimensions of affect heuristics, and perceptions pertaining to high voltage power line risks and benefits. Using original data collected from a statewide Internet survey of 420 local leaders and key policymakers about their opinions on the related issues, other factors claimed by previous literature, including trust, knowledge level, and demographic characteristics are considered. Analytical results suggest that grid-group cultural predispositions, as deeply held core values within local policy elites' individual belief systems, both directly and indirectly -- through affective feelings -- shape perceived utility associated with the installation of high voltage power lines. Recognizing that risk perceptions factor into policy decisions, some practical considerations for better designing policy addressing controversial issues of this nature.

2010-01-01

Devices for continuous glucose monitoring (CGM) are currently a major focus of research in the area of diabetes management. It is envisioned that such devices will have the ability to alert a diabetes patient (or the parent or medical care giver of a diabetes patient) of impending hypoglycemic/hyperglycemic events and thereby enable the patient to avoid extreme hypoglycemic/hyperglycemic excursions as well as minimize deviations outside the normal glucose range, thus preventing both life-threatening events and the debilitating complications associated with diabetes. It is anticipated that CGM devices will utilize constant feedback of analytical information from a glucose sensor to activate an insulin delivery pump, thereby ultimately realizing the concept of an artificial pancreas. Depending on whether the CGM device penetrates/breaks the skin and/or the sample is measured extracorporeally, these devices can be categorized as totally invasive, minimally invasive, and noninvasive. In addition, CGM devices are further classified according to the transduction mechanisms used for glucose sensing (i.e., electrochemical, optical, and piezoelectric). However, at present, most of these technologies are plagued by a variety of issues that affect their accuracy and long-term performance. This article presents a critical comparison of existing CGM technologies, highlighting critical issues of device accuracy, foreign body response, calibration, and miniaturization. An outlook on future developments with an emphasis on long-term reliability and performance is also presented. PMID:21129353

Optimized Kernel Entropy Components.

PubMed

Izquierdo-Verdiguier, Emma; Laparra, Valero; Jenssen, Robert; Gomez-Chova, Luis; Camps-Valls, Gustau

2017-06-01

This brief addresses two main issues of the standard kernel entropy component analysis (KECA) algorithm: the optimization of the kernel decomposition and the optimization of the Gaussian kernel parameter. KECA roughly reduces to a sorting of the importance of kernel eigenvectors by entropy instead of variance, as in the kernel principal components analysis. In this brief, we propose an extension of the KECA method, named optimized KECA (OKECA), that directly extracts the optimal features retaining most of the data entropy by means of compacting the information in very few features (often in just one or two). The proposed method produces features which have higher expressive power. In particular, it is based on the independent component analysis framework, and introduces an extra rotation to the eigen decomposition, which is optimized via gradient-ascent search. This maximum entropy preservation suggests that OKECA features are more efficient than KECA features for density estimation. In addition, a critical issue in both the methods is the selection of the kernel parameter, since it critically affects the resulting performance. Here, we analyze the most common kernel length-scale selection criteria. The results of both the methods are illustrated in different synthetic and real problems. Results show that OKECA returns projections with more expressive power than KECA, the most successful rule for estimating the kernel parameter is based on maximum likelihood, and OKECA is more robust to the selection of the length-scale parameter in kernel density estimation.

The present study describes a response to eight tragic deaths over an eighteen month times span on a fast track construction project on the largest commercial development project in U.S. history. Four versions of a survey were distributed to workers, foremen, superintendents, and senior management. In addition to standard Likert-scale safety climate scale items, an open-ended item was included at the end of the survey. Safety climate perceptions differed by job level. Specifically, management perceived a more positive safety climate as compared to workers. Content analysis of the open-ended item was used to identify important safety and health concerns which might have been overlooked with the qualitative portion of the survey. The surveys were conducted to understand workforce issues of concern with the aim of improving site safety conditions. Such efforts can require minimal investment of resources and time and result in critical feedback for developing interventions affecting organizational structure, management processes, and communication. The most important lesson learned was that gauging differences in perception about site safety can provide critical feedback at all levels of a construction organization. Implementation of multi-level organizational perception surveys can identify major safety issues of concern. Feedback, if acted upon, can potentially result in fewer injuries and fatal events.

Nucleation of Super-Critical Carbon Dioxide in a Venturi Nozzle

NASA Astrophysics Data System (ADS)

Jarrahbashi, Dorrin; Pidaparti, Sandeep; Ranjan, Devesh

2015-11-01

The supercritical carbon dioxide (S-CO2) Brayton cycle combines the primary advantages of the ideal Brayton and Rankine cycles by utilizing CO2 above its critical pressure. In addition to single phase and small back work ratios, supercritical fluids offer other advantages, e.g. heat transfer augmentation and low specific volume. Pressure reduction at the entrance of the compressor may cause homogenous nucleation, vapor production, and collapse of bubbles due to operation near the saturation conditions. Transient behavior of the flow after nucleation may cause serious issues in operation of the cycle and affect the materials used in design. The flow of S-CO2 through a venturi nozzle near the critical point has been studied. A transient compressible 3D Navier-Stokes solver, coupled with continuity, and energy equation has been used. Developed FIT libraries based on a piecewise biquintic spline interpolation of Helmholtz energy have been integrated with OpenFOAM to model S-CO2 properties. The mass fraction of vapor created in the venturi has been calculated using homogeneous equilibrium model (HEM). The flow conditions that lead to nucleation have been investigated. The sensitivity of nucleation to the inlet pressure and temperature, flow rate, and venturi profile has been shown.

Metabolic Management during Critical Illness: Glycemic Control in the ICU.

Honiden, Shyoko; Inzucchi, Silvio E

2015-12-01

Hyperglycemia is a commonly encountered metabolic derangement in the ICU. Important cellular pathways, such as those related to oxidant stress, immunity, and cellular homeostasis, can become deranged with prolonged and uncontrolled hyperglycemia. There is additionally a complex interplay between nutritional status, ambient glucose concentrations, and protein catabolism. While the nuances of glucose management in the ICU have been debated, results from landmark studies support the notion that for most critically ill patients moderate glycemic control is appropriate, as reflected by recent guidelines. Beyond the target population and optimal glucose range, additional factors such as hypoglycemia and glucose variability are important metrics to follow. In this regard, new technologies such as continuous glucose sensors may help alleviate the risks associated with such glucose fluctuations in the ICU. In this review, we will explore the impact of hyperglycemia upon critical cellular pathways and how nutrition provided in the ICU affects blood glucose. Additionally, important clinical trials to date will be summarized. A practical and comprehensive approach to glucose management in the ICU will be outlined, touching upon important issues such as glucose variability, target population, and hypoglycemia.

To critically examine surveillance practices of health visitors (HV) in the UK and public health nurses (PHNs) in Canada. The practice and meaning of surveillance shifts and changes depending on the context and intent of relationships between mothers and HVs or PHNs. We present the context and practice of HVs in the UK and PHNs in Canada and provide a comprehensive literature review regarding surveillance of mothers within public health systems. We then present our critique of the meaning and practice of surveillance across different settings. Concepts from Foucault and discourse analysis are used to critically examine and discuss the meaning of surveillance. Surveillance is a complex concept that shifts meaning and is socially and institutionally constructed through relations of power. Healthcare providers need to understand the different meanings and practices associated with surveillance to effectively inform practice. Healthcare providers should be aware of how their positions of expert and privilege within healthcare systems affect relationships with mothers. A more comprehensive understanding of personal, social and institutional aspects of surveillance will provide opportunities to reflect upon and change practices that are supportive of mothers and their families. © 2017 John Wiley & Sons Ltd.

Supercritical Fluid Chromatography/Fourier Transform Infrared Spectroscopy Of Food Components

Calvey, Elizabeth M.; Page, Samuel W.; Taylor, Larry T.

1989-12-01

Supercritical fluid (SF) technologies are being investigated extensively for applications in food processing. The number of SF-related patents issued testifies to the level of interest. Among the properties of materials at temperatures and pressures above their critical points (supercritical fluids) is density-dependent solvating power. Supercritical CO2 is of particular interest to the food industry because of its low critical temperature (31.3°C) and low toxicity. Many of the components in food matrices react or degrade at elevated temperatures and may be adversely affected by high temperature extractions. Likewise, these components may not be amenable to GC analyses. Our SF research has been in the development of methods employing supercritical fluid chromatography (SFC) and extraction (SFE) coupled to a Fourier transform infrared (FT-IR) spectrometer to investigate food composition. The effects of processing techniques on the isomeric fatty acid content of edible oils and the analysis of lipid oxidation products using SFC/FT-IR with a flow-cell interface are described.

Single-side conduction modeling for high heat flux coolant channels

Boyd, R.D. Sr.

In the development of plasma-facing components (PFCs), most investigators have erroneously postulated negligible water critical heat flux dependence on the coolant channel length-to-diameter (L/D) ratio above a constant value of L/D. Although encouraging results have been obtained in characterizing peaking factors for local two-dimensional boiling curves and critical heat flux, additional experimental data and theoretical model development are needed to validate the applicability to PFCs. Both these and related issues will affect the flow boiling correlation and data reduction associated with the development of PFCs for fusion reactors and other physical problems that are dependent on conduction modeling in themore » heat flux spectrum of applications. Both exact solutions and numerical conjugate analyses are presented for a one-side heated (OSH) geometry. The results show (a) the coexistence of three flow regimes inside an OSH circular geometry, (b) the correlational dependence of the inside wall heat flux and temperature, and (c) inaccuracies that could arise in some data reduction procedures.« less

Abstinence from chronic use of addictive drugs triggers an aversive withdrawal syndrome that compels relapse and deters abstinence. Many features of this syndrome are common across multiple drugs, involving both affective and physical symptoms. Some of the network signaling underlying withdrawal symptoms overlaps with activity that is associated with aversive mood states, including anxiety and depression. Given these shared features, it is not surprising that a particular circuit, the dorsal diencephalic conduction system, and the medial habenula (MHb) and interpeduncular nucleus (IPN), in particular, have been identified as critical to the emergence of aversive states that arise both as a result and, independently, of drug addiction. As the features of this circuit continue to be characterized, the MHb-IPN axis is emerging as a viable target for therapeutics to aid in the treatment of addiction to multiple drugs of abuse as well as mood-associated disorders.

Remote control over fusion of single cells and vesicles has a great potential in biological and chemical research allowing both transfer of genetic material between cells and transfer of molecular content between vesicles. Membrane fusion is a critical process in biology that facilitates molecular transport and mixing of cellular cytoplasms with potential formation of hybrid cells. Cells precisely regulate internal membrane fusions with the aid of specialized fusion complexes that physically provide the energy necessary for mediating fusion. Physical factors like membrane curvature, tension and temperature, affect biological membrane fusion by lowering the associated energy barrier. This has inspired the development of physical approaches to harness the fusion process at a single cell level by using remotely controlled electromagnetic fields to trigger membrane fusion. Here, we critically review various approaches, based on lasers or electric pulses, to control fusion between individual cells or between individual lipid vesicles and discuss their potential and limitations for present and future applications within biochemistry, biology and soft matter.

Backround: Political and sociocultural differences between countries can affect the outcome of clinical and epidemiological studies in ALS. Cross-national studies represent the ideal process by which risk factors can be assessed using the same methodology in different geographical areas. A survey of three European countries (The Netherlands, Ireland and Italy) has been conducted in which incident ALS patients and matched controls were recruited in a population-based study based on age, gender and area of residency, under the Euro-MOTOR systems biology programme of research. We have identified strengths and limitations during the trajectory of the Euro-MOTOR study, from the research design to data analysis. We have analysed the implications of factors including cross-national differences in healthcare systems, sample size, types of matching, the definition of exposures and statistical analysis. Addressing critical methodological aspects of the design of the Euro-MOTOR project minimises bias and will facilitate scientific assessment of the independent role of well-defined exposures.

Sex, gender, and secondhand smoke policies: implications for disadvantaged women.

PubMed

Greaves, Lorraine J; Hemsing, Natalie J

2009-08-01

Although implementation of secondhand smoke policies is increasing, little research has examined the unintended consequences of these policies for disadvantaged women. Macro-, meso-, and micro-level issues connected to secondhand smoke and women are considered to illustrate the range of ways in which sex, gender, and disadvantage affect women's exposure to secondhand smoke. A review of current literature, primarily published between 2000 and 2008, on sex- and gender-based issues related to secondhand smoke exposure and the effects of secondhand smoke policies for various subpopulations of women, including low-income girls and women, nonwhite minority women, and pregnant women, was conducted in 2008. These materials were critically analyzed using a sex and gender analysis, allowing for the drawing of inferences and reflections on the unintended effects of secondhand smoke policies on disadvantaged women. Smoke-free policies do not always have equal or even desired effects on low-income girls and women. Low-income women are more likely to be exposed to secondhand smoke, may have limited capacity to manage their exposure to secondhand smoke both at home and in the workplace, and may experience heightened stigmatization as a result of secondhand smoke policies. Various sex- and gender-related factors, such as gendered roles, unequal power differences between men and women, child-caring roles, and unequal earning power, affect exposure and responses to secondhand smoke, women's capacity to control exposure, and their responses to protective policies. In sum, a much more nuanced gender- and diversity-sensitive framework is needed to develop research and tobacco control policies that address these issues.

A Comparison of Monte Carlo and Deterministic Solvers for keff and Sensitivity Calculations

Haeck, Wim; Parsons, Donald Kent; White, Morgan Curtis

Verification and validation of our solutions for calculating the neutron reactivity for nuclear materials is a key issue to address for many applications, including criticality safety, research reactors, power reactors, and nuclear security. Neutronics codes solve variations of the Boltzmann transport equation. The two main variants are Monte Carlo versus deterministic solutions, e.g. the MCNP [1] versus PARTISN [2] codes, respectively. There have been many studies over the decades that examined the accuracy of such solvers and the general conclusion is that when the problems are well-posed, either solver can produce accurate results. However, the devil is always in themore » details. The current study examines the issue of self-shielding and the stress it puts on deterministic solvers. Most Monte Carlo neutronics codes use continuous-energy descriptions of the neutron interaction data that are not subject to this effect. The issue of self-shielding occurs because of the discretisation of data used by the deterministic solutions. Multigroup data used in these solvers are the average cross section and scattering parameters over an energy range. Resonances in cross sections can occur that change the likelihood of interaction by one to three orders of magnitude over a small energy range. Self-shielding is the numerical effect that the average cross section in groups with strong resonances can be strongly affected as neutrons within that material are preferentially absorbed or scattered out of the resonance energies. This affects both the average cross section and the scattering matrix.« less

Analysis of Phoenix Anomalies and IV & V Findings Applied to the GRAIL Mission

NASA Technical Reports Server (NTRS)

Larson, Steve

2012-01-01

NASA IV&V was established in 1993 to improve safety and cost-effectiveness of mission critical software. Since its inception the tools and strategies employed by IV&V have evolved. This paper examines how lessons learned from the Phoenix project were developed and applied to the GRAIL project. Shortly after selection, the GRAIL project initiated a review of the issues documented by IV&V for Phoenix. The motivation was twofold: the learn as much as possible about the types of issues that arose from the flight software product line slated for use on GRAIL, and to identify opportunities for improving the effectiveness of IV&V on GRAIL. The IV&V Facility provided a database dump containing 893 issues. These were categorized into 16 bins, and then analyzed according to whether the project responded by changing the affected artifacts or using as-is. The results of this analysis were compared to a similar assessment of post-launch anomalies documented by the project. Results of the analysis were discussed with the IV&V team assigned to GRAIL. These discussions led to changes in the way both the project and IV&V approached the IV&V task, and improved the efficiency of the activity.

Electronic Nicotine Delivery Systems (ENDS) were introduced into the US market in 2007, and until recently these devices were unregulated at the federal level. In 2014, the US Food and Drug Administration (FDA) published a Notice of Proposed Rulemaking asserting its intention to regulate ENDS and requesting public comments on numerous related issues, including potential limits on the sale of flavored ENDS. This article analyzes key comments submitted to the FDA on the issue of flavor regulation in ENDS and examines the weight and credibility of the evidence presented by both supporters and opponents of regulation. It also describes the final deeming rule, published in May 2016, and the FDA's response to the evidence submitted. This is the first study to examine public comments submitted to the FDA's Center for Tobacco Products, and it concludes that opponents of regulation were more likely to rely on sources that were not peer reviewed and that were affected by conflicts of interest. In light of these findings, the FDA and the research community should develop processes to carefully and critically analyze public comments submitted to the FDA on issues of tobacco regulation.

Current Status of Research in Teaching and Learning Evolution: I. Philosophical/Epistemological Issues

NASA Astrophysics Data System (ADS)

Smith, Mike U.

2010-06-01

Scholarship that addresses teaching and learning about evolution has rapidly increased in recent years. This review of that scholarship first addresses the philosophical/epistemological issues that impinge on teaching and learning about evolution, including the proper philosophical goals of evolution instruction; the correlational and possibly causal relationships among knowing, understanding, accepting, and believing; and the factors that affect student understanding, acceptance, and/or belief. Second, I summarize the specific epistemological issues involved, including empiricism, naturalism, philosophical vs methodological materialism, science vs religion as non-overlapping magisteria, and science as a way of knowing. Third, the paper critically reviews the strengths and weaknesses of the research tools available to measure the nature of science, epistemological beliefs, and especially the acceptance of evolution. Based on these findings, further research in these areas, especially study of the factors that cause lack of explanatory coherence as well as replications of studies that promise to explain current confusing findings about the interrelationships among student understanding, acceptance, and belief in evolution, are called for. In addition, this review calls for more longitudinal studies to delineate causal connections as well as improved measurement tools.

Metals and lipid oxidation. Contemporary issues.

PubMed

Schaich, K M

1992-03-01

Lipid oxidation is now recognized to be a critically important reaction in physiological and toxicological processes as well as in food products. This provides compelling reasons to understand what causes lipid oxidation in order to be able to prevent or control the reactions. Redox-active metals are major factors catalyzing lipid oxidation in biological systems. Classical mechanisms of direct electron transfer to double bonds by higher valence metals and of reduction of hydroperoxides by lower valence metals do not always account for patterns of metal catalysis of lipid oxidation in multiphasic or compartmentalized biological systems. To explain why oxidation kinetics, mechanisms, and products in molecular environments which are both chemically and physically complex often do not follow classical patterns predicted by model system studies, increased consideration must be given to five contemporary issues regarding metal catalysis of lipid oxidation: hypervalent non-heme iron or iron-oxygen complexes, heme catalysis mechanism(s), compartmentalization of reactions and lipid phase reactions of metals, effects of metals on product mixes, and factors affecting the mode of metal catalytic action.

management challenges of clinical laboratories are more complicated for educational hospital clinical laboratories. Managers can use tools of business intelligence (BI), such as information dashboards that provide the possibility of intelligent decision-making and problem solving about increasing income, reducing spending, utilization management and even improving quality. Critical phase of dashboard design is setting indicators and modeling causal relations between them. The paper describes the process of creating a map for laboratory dashboard. the study is one part of an action research that begins from 2012 by innovation initiative for implementing laboratory intelligent dashboard. Laboratories management problems were determined in educational hospitals by the brainstorming sessions. Then, with regard to the problems key performance indicators (KPIs) specified. the map of indicators designed in form of three layered. They have a causal relationship so that issues measured in the subsequent layers affect issues measured in the prime layers. the proposed indicator map can be the base of performance monitoring. However, these indicators can be modified to improve during iterations of dashboard designing process.

Three countries' experience with Norplant introduction.

Despite international efforts to plan for Norplant introduction, the method has drawn the attention of critics of family planning programmes, and has raised several issues for debate since it was introduced into family planning programmes. The experiences of three countries with the introduction of Norplant highlight some of the unique features of the method that have affected its introduction. Indonesia, Bangladesh and the United States represent diverse cultural settings and systems of family planning provision. Experience in each country has highlighted the need to focus on quality of care for clients, most notably the need for good counselling and attention to removal as well as insertion. The cost of Norplant also has influenced its introduction in each country. Another issue includes the need to work with women's health advocacy groups, which is illustrated particularly in Bangladesh. Finally, the role of litigation in the United States, and its potential role in influencing Norplant introduction in other countries, is discussed. These three countries' experience illustrate the importance of understanding the programmatic context of contraceptive introduction.

The role of theory in qualitative health research.

Kelly, Moira

2010-06-01

The role of theory in qualitative research is often underplayed but it is relevant to the quality of such research in three main ways. Theory influences research design, including decisions about what to research and the development of research questions. Theory underpins methodology and has implications for how data are analyzed and interpreted. Finally, theory about a particular health issue may be developed, contributing to what is already known about the topic that is the focus of the study. This paper will critically consider the role of theory in qualitative primary care research in relation to these three areas. Different approaches to qualitative research will be drawn upon in order to illustrate the ways in which theory might variably inform qualitative research, namely generic qualitative research, grounded theory and discourse analysis. The aim is to describe and discuss key issues and provide practical guidance so that researchers are more aware of the role theory has to play and the importance of being explicit about how theory affects design, analysis and the quality of qualitative research.

Structural Coherence and Temporal Stability of Psychopathic Personality Features During Emerging Adulthood

PubMed Central

Hawes, Samuel W.; Mulvey, Edward P.; Schubert, Carol A.; Pardini, Dustin A.

2015-01-01

Psychopathy is a complex personality disorder characterized by affective, interpersonal, and behavioral dimensions. Although features of psychopathy have been extended downwardly to earlier developmental periods, there is a discerning lack of studies that have focused on critically important issues such as longitudinal invariance and stability/change in these features across time. The current study examines these issues using a large sample of male adolescent offenders (N = 1,170) assessed across 7 annual time points during the transition into emerging adulthood (ages ~ 17 to 24 years). Findings demonstrated that features of psychopathy remained longitudinally invariant across this developmental period, and showed temporally consistent and theoretically coherent associations with other measures of personality, psychopathology, and criminal behaviors. Results also demonstrated that mean levels of psychopathic personality features tended to decrease into emerging adulthood and showed relatively modest rank-order stability across assessments with 7-year lags. These findings suggest that reductions in maladaptive personality features seem to parallel the well-documented decreases in offending that occur during the early 20s. PMID:24978692

Emissions remain a critical issue affecting engine design and operation, while energy conservation is becoming increasingly important. One approach to favorably address these issues is to achieve homogeneous charge combustion and stratified charge combustion at lower peak temperatures with a variable compression ratio, a variable intake temperature and a trapped rate of the EGR using NVO (negative valve overlap). This experiment was attempted to investigate the origins of these lower temperature auto-ignition phenomena with SCCI and CAI using gasoline fuel. In case of SCCI, the combustion and emission characteristics of gasoline-fueled stratified-charge compression ignition (SCCI) engine according to intake temperaturemore » and compression ratio was examined. We investigated the effects of air-fuel ratio, residual EGR rate and injection timing on the CAI combustion area. In addition, the effect of injection timing on combustion factors such as the start of combustion, its duration and its heat release rate was also investigated. (author)« less

A qualitative analysis of the information needs of informal carers of terminally ill cancer patients.

PubMed

Rose, K E

1999-01-01

This article discusses issues relating to information arising from a qualitative study of the experiences of informal carers of terminally ill cancer patients. Qualitative data analysis, drawing on methods of literary criticism, revealed that information was a key area in carers' experience. The findings are presented in the context of needing to provide individualized care to every family and deal with information needs relating to the illness and prognosis. The question of who is in possession of what information is raised, and the effect that this can have on couples is discussed, together with the issue of false information which carers may receive. The discussion centres on the complexity of understanding carers' information needs and considers how these are affected by the context within which carers operate. The work of Glaser and Strauss on awareness contexts is discussed in this respect. Finally, the importance of the nurse's role as a sensitive mediator of information is considered.

Ethnicity and mental health: conceptualization, definition and operationalization of ethnicity from a Canadian context.

The current study provides a critical review of Canadian studies on ethnicity and mental health with respect to the definition, conceptualization and operationalization of ethnicity. It provides a discussion on the methodological issues related to these factors and their implications to guide future research and enable comparability of results across studies. Sociological Abstracts, PsycINFO, MEDLINE and CINAHL were used to identify relevant Canadian articles published between January 1980 and December 2004. The review highlights a number of key issues for future researchers to consider such as the need for: 1) clear rationales as to why ethnicity is important to their outcome of interest; 2) clarity on the definition of ethnicity, which affects its conceptualization and operationalization; 3) a theoretically driven conceptualization of ethnicity, which should be related to the research question of interest; and 4) clear rationales for the decisions made regarding the data source used, the operationalization of ethnicity, and the ethnic categories included in their studies.

Using superheroes such as Hawkeye, Wonder Woman and the Invisible Woman in the physics classroom

Fitzgerald, Barry W.

2018-05-01

Communication of difficult concepts in the physics classroom can be negatively affected by the absence of a strong link between physics content and the experiences or interests of students. One possible method towards addressing this issue is to motivate physics content with reference to popular culture figures such as superheroes. We find ourselves in an age where superhero films are immensely popular with numerous superhero films scheduled for release over the coming years. With many students familiar with many of these characters and their superpowers, superheroes can facilitate a unique platform to aid in the dissemination of physics materials in the classroom. In this paper, we present three examples where superheroes can be used to motivate learning objectives in physics and, if desired, promote critical thinking on behalf of the student. We also reflect on how using the superhero genre in the classroom can be used to address underrepresentation of women, stereotyping, and diversity issues in physics.

Listening to victims: use of a Critical Incident Reporting System to enable adult victims of childhood sexual abuse to participate in a political reappraisal process in Germany.

PubMed

Rassenhofer, Miriam; Spröber, Nina; Schneider, Thekla; Fegert, Jörg M

2013-09-01

Recent revelations about the scope and severity of past child sexual abuse in German institutions set off a broad public debate on this issue, and led to the establishment of a politically appointed Round Table committee and an Independent Commissioner whose mandates were to reappraise the issue and develop recommendations for future policies. A media campaign was launched to publicize the establishment of a Critical Incident Reporting System (CIRS) whereby now-adult victims of past abuse could anonymously provide testimonials and let policy makers know what issues were important to them. Respondents could either call a hotline number or communicate by mail or email. The information collected was documented and analyzed by a research team, and the results of interim reports were included in the recommendations of the Independent Commissioner and the Round Table committee. Most of the respondents described severe and repeated occurrences of childhood sexual abuse. For many, priorities were improvements in therapy and counseling services, the abolishment of the statute of limitations on prosecuting offenders, and financial compensation. Based on the recommendations of the Round Table and the Independent Commissioner, two new laws were adopted as well as an action plan and some guidelines. In addition to rules for recompensation of victims in an institutional context a fund for victims of sexual abuse in intrafamilial context was established by the Federal Government. Another effect of this process was raising societal sensitivity to the problem of child sexual abuse. The use of a CIRS enabled those directly affected by childhood sexual abuse to have some input into a political process designed to address this issue. Such an approach could have applicability in other countries or in other domains of public health and other forms of societal conflict as well. Copyright © 2013 Elsevier Ltd. All rights reserved.

Polyphenol-based nutraceuticals for the control of angiogenesis: Analysis of the critical issues for human use.

PubMed

Morbidelli, Lucia

2016-09-01

Angiogenesis, the formation of new blood-vessel, is crucial in the pathogenesis of several diseases, and thus represents a druggable target for the prevention and treatment of different disorders. It is nowadays well kwon how diet can control cancer development and progression, and how the use of certain diet components can prevent cancer development. Several studies, also from our lab, now indicate that natural plant products including nutraceuticals modulate tumor angiogenesis. In this review, it is reported how phytochemicals, comprising hydroxytyrosol, resveratrol, genistein, curcumin, and the green tea component epigallocatechin-3-gallate among the others, negatively regulate angiogenesis. A single plant-derived compound may affect both endothelial and tumor cells, with the common denominator of anti-inflammatory and radical scavenger activities. Beside these positive features, documented in cellular and animal models, a series of critical issues should be considered from a pharmacological point of view as: what is the best source of bioactive compounds: food and beverages, extracted phytocomplexes, isolated nutraceuticals or synthetic analogues? How is the bioavailability of the compounds of interest in relation to the above source? Is there any biological activity by circulating metabolic derivatives? What is the best formulation, administration route and posology? How safe are in humans? How strong and reliable are the clinical trials designed for their use alone or in combination with conventional chemotherapy? After a dissertation of these critical points, the conclusion can be drawn that novel and effective strategies should be optimized to improve their bioavailability and efficacy, considering their exploitation as chemopreventive and/or curative approaches.

Women are disproportionately affected by HIV in many regions of the world and they represent the fastest growing demographic in the HIV epidemic. In addition, sexual violence against women is a global public health issue which increases women's vulnerability of HIV/STI acquisition. However, the relationship between sexual violence and HIV/STI risk are complex and contribute to the growing epidemic of women infected with HIV/STIs. Our purpose for this review is to examine existing HIV/STI interventions that target women who experience forced sex. Interventions designed to address women's unique needs in HIV/STI prevention are critical in reducing women's vulnerability to HIV/STIs.

Mobile phones' electromagnetic interference with medical devices is an important issue for the medical safety of patients who are using life-supporting medical devices. This review mainly focuses on mobile phones' interference with implanted medical devices and with medical equipment located in critical areas of hospitals. A close look at the findings reveals that mobile phones may adversely affect the functioning of medical devices, and the specific effect and the degree of interference depend on the applied technology and the separation distance. According to the studies' findings and the authors' recommendations, besides mitigating interference, using mobile phones at a reasonable distance from medical devices and developing technology standards can lead to their effective use in hospital communication systems.

Does multilingualism affect the incidence of Alzheimer's disease?: A worldwide analysis by country.

PubMed

Klein, Raymond M; Christie, John; Parkvall, Mikael

2016-12-01

It has been suggested that the cognitive requirements associated with bi- and multilingual processing provide a form of mental exercise that, through increases in cognitive reserve and brain fitness, may delay the symptoms of cognitive failure associated with Alzheimer's disease and other forms of dementia. We collected data on a country-by-country basis that might shed light on this suggestion. Using the best available evidence we could find, the somewhat mixed results we obtained provide tentative support for the protective benefits of multilingualism against cognitive decline. But more importantly, this study exposes a critical issue, which is the need for more comprehensive and more appropriate data on the subject.

Choosing a workstation for daily use in the interpretation of digital radiologic images can be a daunting task. There are numerous products available on the market, but differentiating among them and deciding on what is best for a particular environment can be confusing and frustrating. There is no "one-size-fits-all" workstation, so users must consider a variety of factors when choosing a workstation. This review summarizes the critical elements in a radiology workstation and the characteristics one should be aware of and look for in the selection of a workstation. Issues pertaining to both hardware and software aspects of medical workstations, including interface design, are reviewed, particularly as they may affect the interpretation process. (c) RSNA, 2007.

2000-01-01

A reliable, quantitative assessment of humidification performances of passive heat and moisture exchangers in mechanically-ventilated patients is still to be achieved, although relevant efforts have been made to date. One of the major problems to tackle consists in the difficulty of humidity measurements, both in vivo (during either anaesthesia or intensive care unit treatments) and in vitro set-ups. In this paper a review of the basic operation principles of humidity sensors as well as an analysis of their usage within in vivo and in vitro tests are presented. Particular attention is devoted to the limitations arising from the specific measurement set-up, as they may affect the results notably.

Changing attitudes toward house arrest with electronic monitoring: the impact of a single presentation?

Gainey, Randy R; Payne, Brian K

2003-04-01

The notion that community support is critical for program success is a consistent theme in the literature on community-based corrections. Unfortunately, many citizens know very little about alternative sanctions, are misinformed about them, and do not view them favorably. At issue is whether information about alternative sanctions affects individuals' attitudes regarding them. To address this question, students in an upper division criminal justice course were surveyed before and after a presentation on electronic monitoring. Following the presentation, students were more likely to agree that electronic monitoring is punitive and that it meets several goals of the justice system. Implications for policy makers and educators are provided.

The aerospace community faces tremendous challenges with continued availability of existing material supply chains during the lifecycle of a program. Many obsolescence drivers affect the availability of materials: environmental safety ahd health regulations, vendor and supply economics, market sector demands,and natural disasters. Materials selection has become increasingly more critical when designing aerospace hardware. NASA and DoD conducted a workshop with subject matter experts to discuss issues and define solutions for materials selections during the lifecycle phases of a product/system/component. The three primary lifecycle phases were: Conceptualization/Design, Production & Sustainment, and End of life / Reclamation. Materials obsolescence and pollution prevention considerations were explored for the aforementioned lifecycle phases. The recommended solutions from the workshop are being presented.

Pianosi, Kiersten; Bethune, Cheri; Hurley, Katrina F.

2016-01-01

Background: Specialty career choice is a critical decision for medical students, and research has examined factors influencing particular specialties or assessed it from a demographic perspective. The purpose of this study was to explore and describe influential factors in students' decision-making, irrespective of their particular specialty in a Canadian medical school. Methods: Study participants were recruited from fourth-year medical classes at the Memorial University of Newfoundland in 2003, 2006, 2007 and 2008. Sixteen focus groups (n = 70) were led by a nonfaculty facilitator to uncover factors affecting medical student career choice. The analysis was guided by principles of grounded theory methodology. The focus group transcripts were sequentially coded based on recurring topics and themes that arose in the students' discussions. A set of key themes emerged and representative quotations for each theme were tracked. Results: Twenty themes were identified from the focus group discussions: 7 major, 3 intermediate and 10 minor themes. The major themes were undergraduate experience, exposure, public perception and recruitment, teacher influence, family/outside influences, residency issues and personal philosophy. Intermediate themes included lifestyle, bad-mouthing/negative perceptions and context. Minor themes included critical incidents/experiences, information gaps, uncertainty, nature of the work, extracurricular programs, timing of decision-making, financial issues, prestige, fit with colleagues and gender issues. Interpretation: Exposure to specialties and the timing of this exposure appears to be crucial to career choice, as does the context (who, what, when, where) of any particular rotation. Given the influence of personal philosophy, future research examining students' level of self-assessment and self-reflection in their decision-making processes and level of certainty about their selected specialty would be useful.

Explaining why nurses remain in or leave bedside nursing: a critical ethnography.

PubMed

Mahon, Paula; McPherson, Gladys

2014-09-01

To describe the application of critical ethnography to explain nurses' decisions to remain in or leave bedside nursing, and to describe researcher positioning and reflexivity. Enquiry into hospital nurses' decisions to remain in or leave bedside nursing positions has been conducted from a variety of theoretical perspectives by researchers adopting a range of methodological approaches. This research helps to explain how work environments can affect variables such as job satisfaction and turnover, but provides less insight into how personal and professional factors shape decisions to remain in or leave bedside nursing. A critical theoretical perspective was taken to examine the employment decisions made by nurses in a paediatric intensive care unit (PICU). Data was collected from nurses (n=31) through semi-structured interviews and unobtrusive observation. The authors describe critical ethnography as a powerful research framework for enquiry that allowed them to challenge assumptions about why nurses remain in or leave their jobs, and to explore how issues of fairness and equity contribute to these decisions. Critical ethnography offers a powerful methodology for investigations into complex interactions, such as those between nurses in a PICU. In adopting this methodology, researchers should be sensitised to manifestations of power, attend to their stance and location, and reflexion. The greatest challenges from this research included how to make sense of the insider position, how to acknowledge assumptions and allow these to be challenged, and how to ensure that power relationships in the environment and in the research were attended to.

2016-05-01

The study describes issues that facilitate collaboration in teams of learners in an interprofessional education unit in intensive care. A descriptive qualitative study design was applied using semi-structured interviews based on the critical incident technique and qualitative content analysis. Nineteen participants, eight learners in their specialist training, nine supervisors and two head supervisors in Sweden identified 47 incidents. Teams of learners having control was the core issue. Motivation, time, experiences and reflection were central issues for facilitating collaboration. Efficiently training teams how to collaborate requires learners having control while acting on their common understanding and supervisors taking a facilitating role supporting teams to take control of their critical analysis.

Critical issues using brain-computer interfaces for augmentative and alternative communication.

PubMed

Hill, Katya; Kovacs, Thomas; Shin, Sangeun

2015-03-01

Brain-computer interfaces (BCIs) may potentially be of significant practical value to patients in advanced stages of amyotrophic lateral sclerosis and locked-in syndrome for whom conventional augmentative and alternative communication (AAC) systems, which require some measure of consistent voluntary muscle control, are not satisfactory options. However, BCIs have primarily been used for communication in laboratory research settings. This article discusses 4 critical issues that should be addressed as BCIs are translated out of laboratory settings to become fully functional BCI/AAC systems that may be implemented clinically. These issues include (1) identification of primary, secondary, and tertiary system features; (2) integrating BCI/AAC systems in the World Health Organization's International Classification of Functioning, Disability and Health framework; (3) implementing language-based assessment and intervention; and (4) performance measurement. A clinical demonstration project is presented as an example of research beginning to address these critical issues. Copyright © 2015 American Congress of Rehabilitation Medicine.

Technical issues in the conduct of large space platform experiments in plasma physics and geoplasma sciences

NASA Technical Reports Server (NTRS)

Szuszczewicz, Edward P.

1986-01-01

Large, permanently-manned space platforms can provide exciting opportunities for discoveries in basic plasma and geoplasma sciences. The potential for these discoveries will depend very critically on the properties of the platform, its subsystems, and their abilities to fulfill a spectrum of scientific requirements. With this in mind, the planning of space station research initiatives and the development of attendant platform engineering should allow for the identification of critical science and technology issues that must be clarified far in advance of space station program implementation. An attempt is made to contribute to that process, with a perspective that looks to the development of the space station as a permanently-manned Spaceborne Ionospheric Weather Station. The development of this concept requires a synergism of science and technology which leads to several critical design issues. To explore the identification of these issues, the development of the concept of an Ionospheric Weather Station will necessarily touch upon a number of diverse areas. These areas are discussed.

The potential impacts of migratory difficulty, including warmer waters and altered flow conditions, on the reproductive success of salmonid fishes.

PubMed

Fenkes, Miriam; Shiels, Holly A; Fitzpatrick, John L; Nudds, Robert L

2016-03-01

Climate change and urbanisation of watercourses affect water temperatures and current flow velocities in river systems on a global scale. This represents a particularly critical issue for migratory fish species with complex life histories that use rivers to reproduce. Salmonids are migratory keystone species that provide substantial economical value to ecosystems and human societies. Consequently, a comprehensive understanding of the effects of environmental stressors on their reproductive success is critical in order to ensure their continued abundance during future climatic change. Salmonids are capital breeders, relying entirely on endogenous energy stores to fuel return migration to their natal spawning sites and reproduction upon arrival. Metabolic rates and cost of transport en-route increase with temperature and at extreme temperatures, swimming is increasingly fuelled anaerobically, resulting in an oxygen debt and reduced capacity to recover from exhaustive exercise. Thermally challenged salmonids also produce less viable gametes, which themselves are affected by water temperature after release. Passage through hydrological barriers and temperature changes both affect energy expenditure. As a result, important energetic tradeoffs emerge between extra energy used during migration and that available for other facets of the reproductive cycle, such as reproductive competition and gamete production. However, studies identifying these tradeoffs are extremely sparse. This review focuses on the specific locomotor responses of salmonids to thermal and hydrological challenges, identifying gaps in our knowledge and highlighting the potential implications for key aspects of their reproduction.

Measures of GCM Performance as Functions of Model Parameters Affecting Clouds and Radiation

NASA Astrophysics Data System (ADS)

Jackson, C.; Mu, Q.; Sen, M.; Stoffa, P.

2002-05-01

This abstract is one of three related presentations at this meeting dealing with several issues surrounding optimal parameter and uncertainty estimation of model predictions of climate. Uncertainty in model predictions of climate depends in part on the uncertainty produced by model approximations or parameterizations of unresolved physics. Evaluating these uncertainties is computationally expensive because one needs to evaluate how arbitrary choices for any given combination of model parameters affects model performance. Because the computational effort grows exponentially with the number of parameters being investigated, it is important to choose parameters carefully. Evaluating whether a parameter is worth investigating depends on two considerations: 1) does reasonable choices of parameter values produce a large range in model response relative to observational uncertainty? and 2) does the model response depend non-linearly on various combinations of model parameters? We have decided to narrow our attention to selecting parameters that affect clouds and radiation, as it is likely that these parameters will dominate uncertainties in model predictions of future climate. We present preliminary results of ~20 to 30 AMIPII style climate model integrations using NCAR's CCM3.10 that show model performance as functions of individual parameters controlling 1) critical relative humidity for cloud formation (RHMIN), and 2) boundary layer critical Richardson number (RICR). We also explore various definitions of model performance that include some or all observational data sources (surface air temperature and pressure, meridional and zonal winds, clouds, long and short-wave cloud forcings, etc...) and evaluate in a few select cases whether the model's response depends non-linearly on the parameter values we have selected.

Using action research in nursing practice with older people: democratizing knowledge.

PubMed

Reed, Jan

2005-05-01

This paper reports on an action research study which raised some questions about the processes of developing a sense of shared ownership in action research in a research environment which does not always have the appropriate mechanisms to support and sustain action research. Action research has gained popularity in nursing and healthcare research, offering a way of developing practice-based knowledge, which can assist in changing practice and democratizing inquiry. There are other organizational constraints on action research which arise at different levels, and which also require discussion. These can be issues about communication and ownership at a practice level and issues of funding and project management procedures. This paper reports on a study in which these issues came to the fore, and offers some thoughts on how they can affect the processes of action research. While the principles of action research appear to offer much towards the development of a practice-rooted body of knowledge for nursing, unless some of the issues of ownership are resolved, it is unlikely to move beyond academic rhetoric. If nursing is to engage in action research, this must be done critically and reflectively and careful attention paid to developing an inclusive and collaborative approach to knowledge and practice development. Furthermore, to develop in nursing and health care research, it must find ways to meet the requirements of funding bodies.

Uncertainties in hydrological extremes projections and its effects on decision-making processes in an Amazonian sub-basin.

NASA Astrophysics Data System (ADS)

Andres Rodriguez, Daniel; Garofolo, Lucas; Lazaro Siqueira Junior, Jose

2013-04-01

Uncertainties in Climate Change projections are affected by irreducible uncertainties due to knowledge's limitations, chaotic nature of climate system and human decision-making process. Such uncertainties affect the impact studies, complicating the decision-making process aimed at mitigation and adaptation. However, these uncertainties allow the possibility to develop exploratory analyses on system's vulnerability to different sceneries. Through these kinds of analyses it is possible to identify critical issues, which must be deeper studied. For this study we used several future's projections from General Circulation Models to feed a Hydrological Model, applied to the Amazonian sub-basin of Ji-Paraná. Hydrological Model integrations are performed for present historical time (1970-1990) and for future period (2010-2100). Extreme values analyses are performed to each simulated time series and results are compared with extremes events in present time. A simple approach to identify potential vulnerabilities consists of evaluating the hydrologic system response to climate variability and extreme events observed in the past, comparing them with the conditions projected for the future. Thus it is possible to identify critical issues that need attention and more detailed studies. For the goal of this work, we used socio-economic data from Brazilian Institute of Geography and Statistics, the Operator of the National Electric System, the Brazilian National Water Agency and scientific and press published information. This information is used to characterize impacts associated to extremes hydrological events in the basin during the present historical time and to evaluate potential impacts in the future face to the different hydrological projections. Results show inter-model variability results in a broad dispersion on projected extreme's values. The impact of such dispersion is differentiated for different aspects of socio-economic and natural systems and must be carefully addressed in order to help in decision-making processes.

Human Modeling Evaluations in Microgravity Workstation and Restraint Development

NASA Technical Reports Server (NTRS)

Whitmore, Mihriban; Chmielewski, Cynthia; Wheaton, Aneice; Hancock, Lorraine; Beierle, Jason; Bond, Robert L. (Technical Monitor)

1999-01-01

The International Space Station (ISS) will provide long-term missions which will enable the astronauts to live and work, as well as, conduct research in a microgravity environment. The dominant factor in space affecting the crew is "weightlessness" which creates a challenge for establishing workstation microgravity design requirements. The crewmembers will work at various workstations such as Human Research Facility (HRF), Microgravity Sciences Glovebox (MSG) and Life Sciences Glovebox (LSG). Since the crew will spend considerable amount of time at these workstations, it is critical that ergonomic design requirements are integral part of design and development effort. In order to achieve this goal, the Space Human Factors Laboratory in the Johnson Space Center Flight Crew Support Division has been tasked to conduct integrated evaluations of workstations and associated crew restraints. Thus, a two-phase approach was used: 1) ground and microgravity evaluations of the physical dimensions and layout of the workstation components, and 2) human modeling analyses of the user interface. Computer-based human modeling evaluations were an important part of the approach throughout the design and development process. Human modeling during the conceptual design phase included crew reach and accessibility of individual equipment, as well as, crew restraint needs. During later design phases, human modeling has been used in conjunction with ground reviews and microgravity evaluations of the mock-ups in order to verify the human factors requirements. (Specific examples will be discussed.) This two-phase approach was the most efficient method to determine ergonomic design characteristics for workstations and restraints. The real-time evaluations provided a hands-on implementation in a microgravity environment. On the other hand, only a limited number of participants could be tested. The human modeling evaluations provided a more detailed analysis of the setup. The issues identified during the real-time testing were investigated in the human modeling analyses. In some cases, the opposite was true where preliminary human modeling analyses provided the design engineers with critical issues that needed to be addressed further. This extensive approach provided an effective means to fully address ergonomic design considerations and accurately identify critical issues.

Fostering Critical Thinking in the Geosciences: Combining Geoethics, the Affective Domain, Metacognition, and Systems Thinking

NASA Astrophysics Data System (ADS)

Mogk, D. W.; Geissman, J. W.

2015-12-01

There is a compelling need to develop the geoscience workforce of the future to address the "grand challenges" that face humanity. This workforce must have a strong understanding of Earth history, processes and materials and be able to communicate effectively and responsibly to inform public policy and personal and societal actions, particularly with regard to geohazards and natural resources. Curricula to train future geoscientists must be designed to help students develop critical thinking skills across the curriculum, from introductory to senior capstone courses. Students will be challenged in their pre-professional training as geoscientists as they encounter an incomplete geologic record, ambiguity and uncertainty in observed and experimental results, temporal reasoning ("deep time", frequency, recurrence intervals), spatial reasoning (from microns to mountains), and complex system behavior. Four instructional approaches can be combined to address these challenges and help students develop critical thinking skills: 1) Geoethics and ethical decision making includes review and integration of the context/facts of the situation, stakeholders, decision-makers, and possible alternative actions and expected outcomes; 2) The affective domain which encompasses factors such as student motivation to learn, curiosity, fear, attitudes, perceptions, social barriers and values; 3) Metacognition which encourages students to be aware about their own thinking processes, and to develop self-monitoring and self-regulating behaviors; and 4) Systems thinking which requires integrative thinking about the interactions between physical, chemical, biological and human processes, feedback mechanisms and emergent phenomena. Guided inquiry and scaffolded exercises can be used to present increasingly complex situations that require a thorough understanding of geologic principles and processes as applied to issues of societal concern. These approaches are not "owned" by any single course or instructor, and we encourage all teaching faculty to commit a part of their coursework to develop these critical-thinking skills. A collection of geologic case studies is available at the Teaching Geoethics Across the Geoscience Curriculum website http://serc.carleton.edu/74990.

The International Space Exploration Coordination Group (ISECG) has chosen dust mitigation technology as a Global Exploration Roadmap (GER) critical technology need in order to reduce life cycle cost and risk, and increase the probability of mission success. NASA has also included Particulate Contamination Prevention and Mitigation as a cross-cutting technology to be developed for contamination prevention, cleaning and protection. This technology has been highlighted due to the detrimental effect of dust on both human and robotic missions. During manned Apollo missions, dust caused issues with both equipment and crew. Contamination of equipment caused many issues including incorrect instrument readings and increased temperatures due to masking of thermal radiators. The astronauts were directly affected by dust that covered space suits, obscured face shields and later propagated to the cabin and into the crew's eyes and lungs. Robotic missions on Mars were affected when solar panels were obscured by dust thereby reducing the effectiveness of the solar panels. The Electrostatics and Surface Physics Lab in Swamp Works at the Kennedy Space Center has been developing an Electrodynamic Dust Shield (EDS) to remove dust from multiple surfaces, including glass shields and thermal radiators. This technology has been tested in lab environments and has evolved over several years. Tests of the technology include reduced gravity flights (one-sixth g) in which Apollo Lunar dust samples were successfully removed from glass shields while under vacuum (10(exp -6) kPa).

Food safety issues affecting the dairy beef industry.

Stefan, G

1997-12-01

The ability of dairy farmers to market cull cows and veal calves may be affected by the final rule on Pathogen Reduction and HACCP (Hazard Analysis Critical Control Points) Systems, a sweeping reform of USDA food safety regulations that was published on July 25, 1996. Although the regulations apply only to slaughter and processing plants handling meat and poultry, the rule will have an impact on food animal producers, including dairy farmers. Under this regulation, plant operators are required to evaluate potential hazards and to devise and implement controls that are appropriate for each product and plant to prevent or reduce those hazards. Processing plants may need to consider the potential hazards associated with incoming animals, such as illegal drug residues, which may result in marked changes in the relationships among some producers, livestock markets, and slaughter plants. Such information may actually improve the marketability of some animal classes because documentation will help the packer ensure the safety of products for sale to domestic and foreign markets. Dairy scientists are in an excellent position to explain the food safety issues to dairy farmers and to help develop the appropriate strategies that are necessary to guide the changes needed. These scientists can be conduits for information, the research leaders for practical solutions to reduce public health risks, and valuable resources to help farmers adjust to the impact of these new in-plant regulatory systems.

Independent Orbiter Assessment (IOA): FMEA/CIL assessment

NASA Technical Reports Server (NTRS)

Hinsdale, L. W.; Swain, L. J.; Barnes, J. E.

1988-01-01

The McDonnell Douglas Astronautics Company (MDAC) was selected to perform an Independent Orbiter Assessment (IOA) of the Failure Modes and Effects Analysis (FMEA) and Critical Items List (CIL). Direction was given by the Orbiter and GFE Projects Office to perform the hardware analysis and assessment using the instructions and ground rules defined in NSTS 22206. The IOA analysis featured a top-down approach to determine hardware failure modes, criticality, and potential critical items. To preserve independence, the analysis was accomplished without reliance upon the results contained within the NASA and Prime Contractor FMEA/CIL documentation. The assessment process compared the independently derived failure modes and criticality assignments to the proposed NASA post 51-L FMEA/CIL documentation. When possible, assessment issues were discussed and resolved with the NASA subsystem managers. Unresolved issues were elevated to the Orbiter and GFE Projects Office manager, Configuration Control Board (CCB), or Program Requirements Control Board (PRCB) for further resolution. The most important Orbiter assessment finding was the previously unknown stuck autopilot push-button criticality 1/1 failure mode. The worst case effect could cause loss of crew/vehicle when the microwave landing system is not active. It is concluded that NASA and Prime Contractor Post 51-L FMEA/CIL documentation assessed by IOA is believed to be technically accurate and complete. All CIL issues were resolved. No FMEA issues remain that have safety implications. Consideration should be given, however, to upgrading NSTS 22206 with definitive ground rules which more clearly spell out the limits of redundancy.

Nonreflective Conditions for Perfectly Matched Layer in Computational Aeroacoustics

NASA Astrophysics Data System (ADS)

Choung, Hanahchim; Jang, Seokjong; Lee, Soogab

2018-05-01

In computational aeroacoustics, boundary conditions such as radiation, outflow, or absorbing boundary conditions are critical issues in that they can affect the entire solution of the computation. Among these types of boundary conditions, the perfectly matched layer boundary condition, which has been widely used in computational fluid dynamics and computational aeroacoustics, is developed by augmenting the additional term in the original governing equations by an absorption function so as to stably absorb the outgoing waves. Even if the perfectly matched layer is analytically a perfectly nonreflective boundary condition, spurious waves occur at the interface, since the analysis is performed in discretized space. Hence, this study is focused on factors that affect numerical errors from perfectly matched layer to find the optimum conditions for nonreflective PML. Through a mathematical approach, a minimum width of perfectly matched layer and an optimum absorption coefficient are suggested. To validate the prediction of the analysis, numerical simulations are performed in a generalized coordinate system, as well as in a Cartesian coordinate system.

Bioremediation of waste under ocean acidification: Reviewing the role of Mytilus edulis.

PubMed

Broszeit, Stefanie; Hattam, Caroline; Beaumont, Nicola

2016-02-15

Waste bioremediation is a key regulating ecosystem service, removing wastes from ecosystems through storage, burial and recycling. The bivalve Mytilus edulis is an important contributor to this service, and is used in managing eutrophic waters. Studies show that they are affected by changes in pH due to ocean acidification, reducing their growth. This is forecasted to lead to reductions in M. edulis biomass of up to 50% by 2100. Growth reduction will negatively affect the filtering capacity of each individual, potentially leading to a decrease in bioremediation of waste. This paper critically reviews the current state of knowledge of bioremediation of waste carried out by M. edulis, and the current knowledge of the resultant effect of ocean acidification on this key service. We show that the effects of ocean acidification on waste bioremediation could be a major issue and pave the way for empirical studies of the topic. Copyright © 2016 Elsevier Ltd.

The use of fluoroquinolones (FQs) antibiotics as therapeutic agents and growth promoters is increasing worldwide; however their extensive uses are also resulting in antibiotic resistance among world communities. FQs have also become one of the major contaminants in the waste water bodies, which are not even completely removed during the treatment processes. Furthermore, their abundance in agricultural resources, such as the irrigation water, the bio-solids and the livestock manure can also affect the soil micro-environment. These antibiotics in soil tend to interact in several different ways to affect soil flora and fauna. The current review endeavors to highlight the some critical aspects of FQs prevalence in the environment. The review presents a detailed discussion on the pathways and abundance of FQs in soil. The discussion further spans the issue of sorption and FQs transformation into the soil better understand of their behavior and their toxicity to soil flora and fauna. Copyright © 2017 Elsevier Ltd.

Bernedo Muñoz, Isabel María; Fuentes Rebollo, María Jesús; Fernández-Molina, M; Bersabé Morán, Rosa

2007-11-01

Although parental socialization styles have been investigated in recent years, little research has been carried out on the issue of parental styles in adoptive families. The aim of this research is to analyse parental styles both from the point of view of the parents and of adopted and non-adopted adolescents, taking as covariables the adolescents' sex and age. The sample was made up of 55 adopted adolescents (20 boys and 35 girls with an age range of 11-17 years) and their 55 adoptive parents, and 402 non-adopted adolescents (200 boys and 202 girls with an age range of 11-17 years), and their 258 parents. Two scales evaluated parental styles: the Affect Scale and the Rules and Demands Scale. The results showed that, both from the point of view of the parents and of the adolescents, adoptive families are more affective, communicative and inductive, and less critical and indulgent than non-adoptive families. No differences were found between adopted and non-adopted adolescents on the Parents' Rigidity Scale.

Evaluation of psychology practitioner competence in clinical supervision.

PubMed

Gonsalvez, Craig J; Crowe, Trevor P

2014-01-01

There is a growing consensus favouring the development, advancement, and implementation of a competency-based approach for psychology training and supervision. There is wide recognition that skills, attitude-values, and relationship competencies are as critical to a psychologist's competence as are knowledge capabilities, and that these key competencies are best measured during placements, leaving the clinical supervisor in an unparalleled position of advantage to provide formative and summative evaluations on the supervisee's progression towards competence. Paradoxically, a compelling body of literature from across disciplines indicates that supervisor ratings of broad domains of competence are systematically compromised by biases, including leniency error and halo effect. The current paper highlights key issues affecting summative competency evaluations by supervisors: what competencies should be evaluated, who should conduct the evaluation, how (tools) and when evaluations should be conducted, and process variables that affect evaluation. The article concludes by providing research recommendations to underpin and promote future progress and by offering practice recommendations to facilitate a more credible and meaningful evaluation of competence and competencies.

2012-01-01

In this introduction to the special issue on current thinking in qualitative research and occupational therapy and science, the authors focus on the importance of rigorous qualitative research to inform occupational therapy practice. The authors chosen for this special issue reflect a "second generation of qualitative researchers" who are critical, theoretically sophisticated, methodologically productive, and politically relevant to show that working with disabled clients is political work. Three themes emerged across the articles included in this special issue: (1) recognizing and addressing social justice issues; (2) learning from clients' experiences; and (3) critically reframing occupational therapy's role. These themes can inform occupational therapy practice, research, and education to reflect a more client-centered and politically engaging approach. Copyright 2012, SLACK Incorporated.

Risk communication and trust in decision-maker action: a case study of the Giant Mine Remediation Plan.

Jardine, Cynthia G; Banfield, Laura; Driedger, S Michelle; Furgal, Christopher M

2013-01-01

The development and implementation of a remediation plan for the residual arsenic trioxide stored at the former Giant Mine site in the Canadian Northwest Territories has raised important issues related to trust. Social and individual trust of those responsible for making decisions on risks is critically important in community judgements on risk and the acceptability of risk management decisions. Trust is known to be affected by value similarity and confidence in past performance, which serve as interacting sources of cooperation in acting toward a common goal. To explore the elements of trust associated with the development and implementation of the Giant Mine Remediation Plan. Semi-structured interviews were conducted with eight purposively selected key informants representing both various interested and affected parties and the two government proponents. Five primary issues related to trust were identified by the participants: (1) a historical legacy of mistrust between the community (particularly Aboriginal peoples) and government; (2) barriers to building trust with the federal government; (3) limited community input and control over the decision-making process; (4) the conflicted and confounded role of the government agencies being both proponent and regulator, and the resulting need for independent oversight; and (5) distrust of the government to commit to the perpetual care required for the remediation option selected. The dual-mode model of trust and confidence was shown to be a useful framework for understanding the pivotal role of trust in the development of the Giant Mine Remediation Plan. Failure to recognize issues of trust based on value dissimilarity and lack of confidence based on past performance have resulted in a lack of cooperation characterized by delayed remediation and a prolonged and expensive consultation process. Government recognition of the importance of trust to these issues will hopefully improve future communication and public engagement endeavours.

Legal considerations during pediatric emergency mass critical care events.

PubMed

Courtney, Brooke; Hodge, James G

2011-11-01

Recent public health emergencies, such as the 2009 Influenza A/H1N1 Pandemic and Hurricane Katrina, underscore the importance of developing healthcare response plans and protocols for disasters impacting large populations. Significant research and scholarship, including the 2009 Institute of Medicine report on crisis standards of care and the 2008 Task Force for Mass Critical Care recommendations, provide guidance for healthcare responses to catastrophic emergencies. Most of these efforts recognize but do not focus on the unique needs of pediatric populations. In 2008, the Centers for Disease Control and Prevention supported the formation of a task force to address pediatric emergency mass critical care response issues, including legal issues. Liability is a significant concern for healthcare practitioners and facilities during pediatric emergency mass critical care that necessitates a shift to crisis standards of care. This article describes the legal considerations inherent in planning for and responding to catastrophic health emergencies and makes recommendations for pediatric emergency mass critical care legal preparedness. The Pediatric Emergency Mass Critical Care Task Force, composed of 36 experts from diverse public health, medical, and disaster response fields, convened in Atlanta, GA, on March 29-30, 2010, to review the pediatric emergency mass critical care recommendations developed by a 17-member steering committee. During the meeting, experts determined that the recommendations would be strengthened by a manuscript addressing legal issues. Authors drafted the manuscript through consensus-based study of peer-reviewed research, literature reviews, and expert opinion. The manuscript was reviewed by Pediatric Emergency Mass Critical Care Steering Committee members and additional legal counsel and revised. While the legal issues associated with providing pediatric emergency mass critical care are not unique within the overall context of disaster healthcare, the scope of the parens patriae power of states, informed consent principles, and security should be considered in pediatric emergency mass critical care planning and response efforts because parents and legal guardians may be unavailable to participate in healthcare decision making during disasters. In addition, practitioners who follow properly vetted and accepted pediatric emergency mass critical care disaster protocols in good faith should be protected from civil liability, and healthcare facilities that provide pediatric care should incorporate informed consent and security protocols into their disaster plans.

Strategic management of the health workforce in developing countries: what have we learned?

PubMed

Fritzen, Scott A

2007-02-26

The study of the health workforce has gained in prominence in recent years, as the dynamic interconnections between human resource issues and health system effectiveness have come into sharper focus. This paper reviews lessons relating to strategic management challenges emerging from the growing literature in this area. Workforce issues are strategic: they affect overall system performance as well as the feasibility and sustainability of health reforms. Viewing workforce issues strategically forces health authorities to confront the yawning gaps between policy and implementation in many developing countries. Lessons emerge in four areas. One concerns imbalances in workforce structure, whether from a functional specialization, geographical or facility lens. These imbalances pose a strategic challenge in that authorities must attempt to steer workforce distribution over time using a limited range of policy tools. A second group of lessons concerns the difficulties of central-level steering of the health workforce, often critically weak due to the lack of proper information systems and the complexities of public sector decentralization and service commercialization trends affecting the grassroots.A third cluster examines worker capacity and motivation, often shaped in developing countries as much by the informal norms and incentives as by formal attempts to support workers or to hold them accountable. Finally, a range of reforms centering on service contracting and improvements to human resource management are emerging. Since these have as a necessary (but not sufficient) condition some flexibility in personnel practices, recent trends towards the sharing of such functions with local authorities are promising. The paper identifies a number of current lines of productive research, focusing on the relationship between health policy reforms and the local institutional environments in which the workforce, both public and private, is deployed.

Third-world development: urbanizing for the future.

PubMed

Mcilwaine, C

1997-01-01

This article reviews some issues reflected in the 1996 UN Habitat II agenda and recent research on urbanization. The themes of the 1996 Habitat conference were urban development, urban poverty, and governance, civil society, and social capital. It is expected that over 50% of total world population will live in cities in the year 2000. Cities are viewed both as engines of economic growth and centers of severe economic, environmental, and social problems. There is some disagreement about whether cities are rational economic structures or what the World Bank's urban agenda is and its relationship with macroeconomic policy. Discussions of global urban issues are criticized for their neglect of issues of equity and poverty, cultural diversity, and identity and representation. Habitat II also stressed urban sustainability. There is growing recognition that urban management involves more than the "Brown Agenda" of environmental and physical aspects of urban growth. Recent studies identify how politics and power affect people's access to basic urban services. Urban economic activity can also contribute to environmental problems. Urban growth affects the provision of health services. Although there is not a consensus on the role of cities in expanding economic and social development and the best management practices, there is sufficient evidence to indicate that urban processes are varied throughout the developing world. The links between urban and rural areas differentiate cities and expose the need to understand the role of intermediate urban areas surrounding and between larger cities. Poverty has become increasingly urbanized, but the extent of poverty is unknown. Habitat II was an unprecedented effort to engage nongovernment groups, local government staff, trade unions, and the private sector and to emphasize community participation. Networks of trust and reciprocity are key to solving poverty, inequality, and disempowerment problems.

Ethical issues in pediatric emergency mass critical care.

PubMed

Antommaria, Armand H Matheny; Powell, Tia; Miller, Jennifer E; Christian, Michael D

2011-11-01

As a result of recent events, including natural disasters and pandemics, mass critical care planning has become a priority. In general, planning involves limiting the scope of disasters, increasing the supply of medical resources, and allocating scarce resources. Entities at varying levels have articulated ethical frameworks to inform policy development. In spite of this increased focus, children have received limited attention. Children require special attention because of their unique vulnerabilities and needs. In May 2008, the Task Force for Mass Critical Care published guidance on provision of mass critical care to adults. Acknowledging that the critical care needs of children during disasters were unaddressed by this effort, a 17-member Steering Committee, assembled by the Oak Ridge Institute for Science and Education with guidance from members of the American Academy of Pediatrics, convened in April 2009 to determine priority topic areas for pediatric emergency mass critical care recommendations.Steering Committee members established subgroups by topic area and performed literature reviews of MEDLINE and Ovid databases. Draft documents were subsequently developed and revised based on the feedback from the Task Force. The Pediatric Emergency Mass Critical Care Task Force, composed of 36 experts from diverse public health, medical, and disaster response fields, convened in Atlanta, GA, on March 29-30, 2010. This document reflects expert input from the Task Force in addition to the most current medical literature. The Ethics Subcommittee recommends that surge planning seek to provide resources for children in proportion to their percentage of the population or preferably, if data are available, the percentage of those affected by the disaster. Generally, scarce resources should be allocated on the basis of need, benefit, and the conservation of resources. Estimates of need, benefit, and resource utilization may be more subjective or objective. While the Subcommittee favors more objective methods, pediatrics lacks a simple, validated scoring system to predict benefit or resource utilization. The Subcommittee hesitantly recommends relying on expert opinion while pediatric triage tools are developed. If resources remain inadequate, they should then be allocated based on queuing or lottery. Choosing between these methods is based on ethical, psychological, and practical considerations upon which the Subcommittee could not reach consensus. The Subcommittee unanimously believes the proposal to favor individuals between 15 and 40 yrs of age is inappropriate. Other age-based criteria and criteria based on social role remain controversial. The Subcommittee recommends continued work to engage all stakeholders, especially the public, in deliberation about these issues.

Children represent one quarter of the US population. Because of its enormous size and special needs, it is critically important to address this population group in pandemic influenza planning. Here we describe the ways in which children are vulnerable in a pandemic, provide an overview of existing plans, summarize the resources available, and, given our experience with influenza A(H1N1), outline the evolving lessons we have learned with respect to planning for a severe influenza pandemic. We focus on a number of issues affecting children—vaccinations, medication availability, hospital capacity, and mental health concerns—and emphasize strategies that will protect children from exposure to the influenza virus, including infection control practices and activities in schools and child care programs.

Built environment change: a framework to support health-enhancing behaviour through environmental policy and health research.

PubMed

Berke, Ethan M; Vernez-Moudon, Anne

2014-06-01

As research examining the effect of the built environment on health accelerates, it is critical for health and planning researchers to conduct studies and make recommendations in the context of a robust theoretical framework. We propose a framework for built environment change (BEC) related to improving health. BEC consists of elements of the built environment, how people are exposed to and interact with them perceptually and functionally, and how this exposure may affect health-related behaviours. Integrated into this framework are the legal and regulatory mechanisms and instruments that are commonly used to effect change in the built environment. This framework would be applicable to medical research as well as to issues of policy and community planning.

Facial attractiveness: evolutionary based research.

Little, Anthony C; Jones, Benedict C; DeBruine, Lisa M

2011-06-12

Face preferences affect a diverse range of critical social outcomes, from mate choices and decisions about platonic relationships to hiring decisions and decisions about social exchange. Firstly, we review the facial characteristics that influence attractiveness judgements of faces (e.g. symmetry, sexually dimorphic shape cues, averageness, skin colour/texture and cues to personality) and then review several important sources of individual differences in face preferences (e.g. hormone levels and fertility, own attractiveness and personality, visual experience, familiarity and imprinting, social learning). The research relating to these issues highlights flexible, sophisticated systems that support and promote adaptive responses to faces that appear to function to maximize the benefits of both our mate choices and more general decisions about other types of social partners.

The Googlization of health research: from disruptive innovation to disruptive ethics.

PubMed

Sharon, Tamar

2016-11-01

Consumer-oriented mobile technologies offer new ways of capturing multidimensional health data, and are increasingly seen as facilitators of medical research. This has opened the way for large consumer tech companies, like Apple, Google, Amazon and Facebook, to enter the space of health research, offering new methods for collecting, storing and analyzing health data. While these developments are often portrayed as 'disrupting' research in beneficial ways, they also raise many ethical issues. These can be organized into three clusters: questions concerning the quality of research; privacy/informed consent; and new power asymmetries based on access to data and control over technological infrastructures. I argue that this last cluster, insofar as it may affect future research agendas, deserves more critical attention.

Plasma cell mastitis is an inflammatory disease of the breast parenchyma, rare in males. In the last 40 years, few cases have been described in literature. Our recent treatment of male patients affected by plasma cell mastitis raised a series of issues which led us to carry out a critical review of the literature. Plasma cell mastitis is often not well defined and is difficult to assess by clinical examination and radiological investigation alone. An understanding of the pathogenesis and the mechanisms behind plasma cell mastitis may help improve the diagnostic and therapeutic course of the disease, leading to a more targeted and less invasive treatment.

Facial attractiveness: evolutionary based research

PubMed Central

Little, Anthony C.; Jones, Benedict C.; DeBruine, Lisa M.

2011-01-01

Face preferences affect a diverse range of critical social outcomes, from mate choices and decisions about platonic relationships to hiring decisions and decisions about social exchange. Firstly, we review the facial characteristics that influence attractiveness judgements of faces (e.g. symmetry, sexually dimorphic shape cues, averageness, skin colour/texture and cues to personality) and then review several important sources of individual differences in face preferences (e.g. hormone levels and fertility, own attractiveness and personality, visual experience, familiarity and imprinting, social learning). The research relating to these issues highlights flexible, sophisticated systems that support and promote adaptive responses to faces that appear to function to maximize the benefits of both our mate choices and more general decisions about other types of social partners.

Semple, Shirley J.; Strathdee, Steffanie A.; Zians, Jim; Patterson, Thomas L.

2012-01-01

Retrospective reports of children’s relationships with their parents have been associated with increased risk for depressive symptoms in adulthood. This study examined four dimensions of the current mother-child relationship (affection, criticism, over-involvement, conflict) in relation to depressive symptoms in a sample of 270 HIV-positive men who have sex with men (MSM). Depressive symptoms were positively associated with overt conflict or disagreement with mothers and perceived over-involvement by mothers, and inversely related to frequency of contact with mothers. These findings suggest that clinicians who treat HIV-positive methamphetamine-using MSM with depressive symptoms should evaluate issues in the mother-son relationship and consider family-based therapies as an adjunct to treatment.

Space Allocation in the Award-Winning Adult ICUs of the Last Two Decades (1993-2012): An Exploratory Study.

PubMed

Rashid, Mahbub

2014-01-01

This exploratory study describes space allocation among different generic categories of functions in adult intensive care units (ICUs) showing how the amount of space of any one functional category is related to that of another functional category, and how different strategic choices, such as size, construction type, specialty type, and layout type, affect space allocation in these ICUs. Even though critical care practice has already undergone significant changes in the last few decades, it is still an evolving domain of medical practice. As a result, ICU design is also evolving as new regulatory standards, new technologies, and new clinical models are being introduced. A good understanding of the above issues regarding space allocation may help us better guide the evolution of ICU design. The study includes a set of 25 adult ICUs that were recognized between 1993 and 2012 by the Society of Critical Care Medicine (SCCM), the American Association of Critical Care Nurses (AACCN), and the American Institute of Architects Academy of Architecture for Health (AIA AAH) for their efforts to promote healing of the critically ill and injured patients through the design of the critical care unit environment. The study finds notable differences in space allocation among different generic categories of functions between the ICUs of the first decade (1993-2002) and the second decade (2003-2012). The study also finds notable differences in space allocation among different generic categories of functions in relation to size, construction type, specialty type, and layout type. Despite several limitations, the study should help design better adult ICUs based on an evidence-based understanding of the relationships between space allocation and strategic choices.

Codevelopment of conceptual understanding and critical attitude: toward a systemic analysis of the survival blanket

NASA Astrophysics Data System (ADS)

Viennot, Laurence; Décamp, Nicolas

2016-01-01

One key objective of physics teaching is the promotion of conceptual understanding. Additionally, the critical faculty is universally seen as a central quality to be developed in students. In recent years, however, teaching objectives have placed stronger emphasis on skills than on concepts, and there is a risk that conceptual structuring may be disregarded. The question therefore arises as to whether it is possible for students to develop a critical stance without a conceptual basis, leading in turn to the issue of possible links between the development of conceptual understanding and critical attitude. In an in-depth study to address these questions, the participants were seven prospective physics and chemistry teachers. The methodology included a ‘teaching interview’, designed to observe participants’ responses to limited explanations of a given phenomenon and their ensuing intellectual satisfaction or frustration. The explanatory task related to the physics of how a survival blanket works, requiring a full and appropriate system analysis of the blanket. The analysis identified five recurrent lines of reasoning and linked these to judgments of adequacy of explanation, based on metacognitive/affective (MCA) factors, intellectual (dis)satisfaction and critical stance. Recurrent themes and MCA factors were used to map the intellectual dynamics that emerged during the interview process. Participants’ critical attitude was observed to develop in strong interaction with their comprehension of the topic. The results suggest that most students need to reach a certain level of conceptual mastery before they can begin to question an oversimplified explanation, although one student’s replies show that a different intellectual dynamics is also possible. The paper ends with a discussion of the implications of these findings for future research and for decisions concerning teaching objectives and the design of learning environments.

Treating 'AIDS blindness': a critical pedagogical approach to HIV education at tertiary level.

PubMed

Wood, Lesley; Rens, Julialet

2014-01-01

HIV and AIDS affect all South Africans, irrespective of gender, race, age and economic status. Teachers should therefore be able to meaningfully integrate HIV content into the school curriculum. However, pre-service teacher education programmes still do not pay adequate attention to HIV education, particularly in institutions where students are being prepared to work in environments that are perceived to be unaffected by the consequences of the pandemic. This article advocates that HIV education should be integrated into contexts of privilege and presents evidence of the influence that a critical pedagogical approach can have on changing student perceptions of the need to address HIV in and through their teaching. We led 109 Post-graduate Certificate of Education students through a series of activities that required them to critically reflect on their feelings, attitudes and perceived skills with regard to HIV and AIDS education; to identify potential areas of personal change; and to begin to imagine alternative professional possibilities. We generated qualitative data through drawings, group discussions, individual written reflections, and a voluntary focus group. A content analysis of the data revealed that the participating students initially felt incompetent to incorporate HIV and related issues into their teaching, and felt hesitant and uncomfortable at the prospect. However, a critical reflection on their thinking, both individually and in a group setting, served to shift them towards a more holistic, critical and humanising understanding of the pandemic and the role they could play as future teachers in helping to mitigate its impact. The findings provide evidence that a critical pedagogical approach - particularly with groups who believe that HIV and AIDS is not something that concerns them - can provide an effective way to mediate the knowledge, skills and attitudes that competent teachers need in today's world.

Brazil, Kevin; Kassalainen, Sharon; Ploeg, Jenny; Marshall, Denise

2010-11-01

Health care providers regularly encounter situations of moral conflict and distress in their practice. Moral distress may result in unfavorable outcomes for both health care providers and those in their care. The purpose of this study was to examine the experience of moral distress from a broad range of health care occupations that provide home-based palliative care as the initial step of addressing the issue. A critical incident approach was used in qualitative interviews to elicit the experiences on moral distress from 18 health care providers drawn from five home visiting organizations in south central Ontario, Canada. Most participants described at least two critical incidents in their interview generating a total of 47 critical incidents. Analyses of the critical incidents revealed 11 issues that triggered moral distress which clustered into three themes, (a) the role of informal caregivers, b) challenging clinical situations and (c) service delivery issues. The findings suggest that the training and practice environments for health care providers need to be designed to recognize the moral challenges related to day-to-day practice.

Students' qualification in environmental and sustainability education—epistemic gaps or composites of critical thinking?

NASA Astrophysics Data System (ADS)

Hasslöf, Helen; Lundegård, Iann; Malmberg, Claes

2016-01-01

In an 'age of measurement' where students' qualification is a hot topic on the political agenda, it is of interest to ask what the function of qualification might implicate in relation to a complex issue as Education for Sustainable Development (ESD) and what function environmental and sustainability issues serve in science education. This paper deals with how secondary and upper secondary teachers in discussions with colleagues articulate qualification in relation to educational aims of ESD. With inspiration from discourse theory, the teachers' articulations of qualification are analysed and put in relation to other functions of education (qualification, socialisation and subjectification). The results of this study show three discourses of qualification: scientific reasoning, awareness of complexity and to be critical. The discourse of 'qualification as to be critical' is articulated as a composite of differing epistemological views. In this discourse, the teachers undulate between rationalistic epistemological views and postmodern views, in a pragmatic way, to articulate a discourse of critical thinking which serves as a reflecting tool to bring about different ways of valuing issues of sustainability, which reformulates 'matter of facts' towards 'matter of concerns'

Sommeregger, Wolfgang; Sissolak, Bernhard; Kandra, Kulwant; von Stosch, Moritz; Mayer, Martin; Striedner, Gerald

2017-07-01

The industrial production of complex biopharmaceuticals using recombinant mammalian cell lines is still mainly built on a quality by testing approach, which is represented by fixed process conditions and extensive testing of the end-product. In 2004 the FDA launched the process analytical technology initiative, aiming to guide the industry towards advanced process monitoring and better understanding of how critical process parameters affect the critical quality attributes. Implementation of process analytical technology into the bio-production process enables moving from the quality by testing to a more flexible quality by design approach. The application of advanced sensor systems in combination with mathematical modelling techniques offers enhanced process understanding, allows on-line prediction of critical quality attributes and subsequently real-time product quality control. In this review opportunities and unsolved issues on the road to a successful quality by design and dynamic control implementation are discussed. A major focus is directed on the preconditions for the application of model predictive control for mammalian cell culture bioprocesses. Design of experiments providing information about the process dynamics upon parameter change, dynamic process models, on-line process state predictions and powerful software environments seem to be a prerequisite for quality by control realization. © 2017 The Authors.

2017-10-01

The high proportion of ductal carcinoma in situ (DCIS) presented in mammographic screening and the relatively low risk of progression to invasive disease have raised questions related to overtreatment. Following a review of current DCIS management protocols a more conservative approach has been suggested. Clinical trials have been introduced to evaluate the option of avoiding surgical intervention in a proportion of patients with DCIS defined as "low-risk" using certain clinicopathological criteria. These trials can potentially provide evidence-based models of active surveillance (with or without endocrine therapy) as a future management approach. Despite the undisputable fact of our need to address the obvious overtreatment of screen-detected DCIS, some important questions need to be considered regarding these trials including the eligibility criteria and definition of risk, the proportion of patient eligible for inclusion, and the length of time required for proper analysis of the trials' outcome in view of the long-term natural history of DCIS progression particularly the low-risk group. These factors can potentially affect the practicality and future impact of such trials. This review provides critical analysis of current DCIS management trials and highlights critical issues related to their practicality and the expected outcome. Copyright © 2017 Elsevier Ltd.

The evolving understanding of the construct of intellectual disability.

PubMed

Schalock, Robert L

2011-12-01

This article addresses two major areas concerned with the evolving understanding of the construct of intellectual disability. The first part of the article discusses current answers to five critical questions that have revolved around the general question, "What is Intellectual Disability?" These five are what to call the phenomenon, how to explain the phenomenon, how to define the phenomenon and determine who is a member of the class, how to classify persons so defined and identified, and how to establish public policy regarding such persons. The second part of the article discusses four critical issues that will impact both our future understanding of the construct and the approach taken to persons with intellectual disability. These four critical issues relate to the conceptualisation and measurement of intellectual functioning, the constitutive definition of intellectual disability, the alignment of clinical functions related to diagnosis, classification, and planning supports, and how the field resolves a number of emerging epistemological issues.

Dryland ecohydrology and climate change: critical issues and technical advances

2012-04-01

Drylands cover about 40% of the terrestrial land surface and account for approximately 40% of global net primary productivity. Water is fundamental to the biophysical processes that sustain ecosystem function and food production, particularly in drylands, where a tight coupling exists between water resource availability and ecosystem productivity, surface energy balance, and biogeochemical cycles. Currently, drylands support at least 2 billion people and comprise both natural and managed ecosystems. In this synthesis, we identify some current critical issues in the understanding of dryland systems and discuss how arid and semiarid environments are responding to the changes in climate and land use. Specifically, we focus on dryland agriculture and food security, dryland population growth, desertification, shrub encroachment and dryland development issues as factors of change requiring increased understanding and management. We also review recent technical advances in the quantitative assessment of human versus climate change related drivers of desertification, evapotranspiration partitioning using field deployable stable water isotope systems and the remote sensing of key ecohydrological processes. These technological advances provide new tools that assist in addressing major critical issues in dryland ecohydrology under climate change

Critical Issues in the Lives of Children and Youth Who Are Deafblind.

2016-01-01

The coeditors of an American Annals of the Deaf special issue on deaf-blindness introduce readers to critical issues surrounding children and youth who are deafblind. These issues-early identification, communication, social-emotional needs, family and multicultural issues, universal design and assistive technology, transition planning, and personnel preparation-are explored further in the articles that follow. By way of introduction, the present article provides definitions of deafblindness and a discussion of the heterogeneous nature of the population. The history of the field of deafblindness is then explored in terms of three distinct population shifts, from (a) individuals of the 18th and 19th centuries who became deafblind due to illness, to (b) the influx of individuals with congenital rubella syndrome in the 1960s who had disabilities besides deafblindness, and (c) the current population of children and youth with deafblindness, which includes individuals with other complex disabilities.

Improving Caregivers' Perceptions Regarding Patient Goals of Care/End-of-Life Issues for the Multidisciplinary Critical Care Team.

PubMed

Wessman, Brian T; Sona, Carrie; Schallom, Marilyn

2017-01-01

With population aging and growth, use of critical care medicine at the end of life continues to rise, while many critical care providers are not adequately trained regarding goals of care/end-of-life (GOC/EOL) issues. A multidisciplinary intensive care unit (ICU) team intervention regarding GOC/EOL communication will enhance the clinical abilities of all critical care providers when discussing GOC/EOL issues and increase ICU staff comfort level while improving transitions for patients to a comfort care approach. This study was a preintervention/postintervention survey evaluation. This study was conducted at an academic tertiary surgical burn trauma ICU. The intervention was provided to nursing, ancillary staff, house staff, and attending physicians. An initial survey was circulated among the critical care staff for baseline expectations, satisfaction, and understanding of GOC/EOL care. A robust intervention was begun including the creation of a multidisciplinary GOC/EOL team, communication tools for providers, patient-family pamphlets, standardized EOL order sets, and formalized didactic sessions. Subsequently, the same survey was circulated and compared to baseline data. Preintervention/postintervention survey data were reviewed and statistically analyzed. Our survey response rate for preintervention/postintervention was 50.4% and 36.1%, respectively. The intervention generated heightened interest in improving family communication and provided focal direction to foster this growth. Based on the serial surveys regarding our intervention, statistically significant staff improvements were seen in "work stress" (P = .04), "EOL information" (P = .006), and "space allotment" (P = .001). Improved congruence of families and health care providers regarding decision over intensity of care was also noted. We created a novel unit-based multidisciplinary program for improved EOL/GOC approaches in the critical care setting. A similarly formatted program could be adapted by other ICUs. Benefits of such a program include improving caregivers' perceptions regarding EOL/GOC issues and fostering critical care team growth. © The Author(s) 2015.

This case study illustrates a participatory framework for confronting critical community health issues using 'grass-roots' research-guided community-defined interventions. Ongoing work in Cambodia has culturally adapted research, theory and practice for particular, local health-promotion responses to HIV/AIDS, alcohol abuse and other challenges in the community of Siem Reap. For resource-poor communities in Cambodia, we recycle such 'older' concepts as 'empowerment' and 'action research'. We re-imagine community health psychology, when confronted with 'critical', life-and-death issues, as adjusting its research and practices to local, particular ontological and epistemological urgencies of trauma, morbidity and mortality.

Sustainability assessment for the transportation environment of Darjeeling, India.

Nag, Dipanjan; Paul, Subrata Kr; Saha, Swati; Goswami, Arkopal K

2018-05-01

Darjeeling is an important tourist hill town of West Bengal, India. It suffers from an acute problem of transportation, particularly during its peak tourist seasons due to limited road space, inadequate public transport facilities and indiscriminate use of automobiles. This hill town was originally designed for a population of 10,000, but over the years, it has come face-to-face with rapid urbanization, a rising population of both tourists and residents and intensifying motor vehicle usage. These factors together are posing a threat to its transport environment. This study identifies the Sustainable Transport Indicators (STIs) available in the existing literature to identify the critical stretches using Analytical Hierarchy Process (AHP) based on experts' consensus. It was found that the experts placed emphasis on the mobility of the town, talking about vehicular impact on air pollution and encroachment of roads as the main issues affecting the sustainability of the transport environment. Thereafter, policy-level interventions have been suggested in accordance with the identified sustainability issues. We trust that other tourist hill towns with issues similar to Darjeeling could easily emulate the study methodology to assess their transport environment sustainability, or replicate on the lines of the recommended policy interventions.

Ethical issues in genetic counselling with special reference to haemoglobinopathies.

PubMed

Muthuswamy, Vasantha

2011-10-01

Genetic counselling is provided in places where genetic tests are carried out. The process involves pre-test counselling as well as post-test counselling to enable the individuals to face the situation and take appropriate decisions with the right frame of mind. Major ethical principles which govern the attitudes and actions of counsellors include: respect for patient autonomy, non-maleficence, beneficence, or taking action to help benefit others and prevent harm, both physical and mental, and justice, which requires that services be distributed fairly to those in need. Other moral issues include veracity, the duty to disclose information or to be truthful, and respect for patient confidentiality. Nondirective counselling, a hallmark of this profession, is in accordance with the principle of individual autonomy. High prevalence of haemoglobinopathies with availability of good and sensitive carrier detection tests and prenatal diagnostic techniques makes these good candidates for population screening of carriers along with genetic counselling for primary prevention of the disease. Screening of the extended family members of the affected child, high risk communities and general population screening including antenatal women are the main target groups for planning a Haemoglobinopathy control programme. A critical mass of trained genetic counsellors who have understanding of the ethical issues and its appropriate handling with the required sensitivity is needed in India.

The U.S. Department of Energy (DOE) chartered the Phosphoric Acid Fuel-Cell (PAFC) Bus Program to demonstrate the feasibility of fuel cells in heavy-duty transportation systems. As part of this program, PAFC- powered buses are being built to meet transit industry design and performance standards. Test-bed bus-1 (TBB-1) was designed in 1993 and integrated in March 1994. TBB-2 and TBB-3 are under construction and should be integrated in early 1995. In 1987 Phase I of the program began with the development and testing of two conceptual system designs- liquid- and air-cooled systems. The liquid-cooled PAFC system was chosen to continue, throughmore » a competitive award, into Phase H, beginning in 1991. Three hybrid buses, which combine fuel-cell and battery technologies, were designed during Phase III. After completing Phase II, DOE plans a comprehensive performance testing program (Phase HI) to verify that the buses meet stringent transit industry requirements. The Phase III study will evaluate the PAFC bus and compare it to a conventional diesel bus. This NREL study assesses the environmental, health, and safety (EH&S) issues that may affect the commercialization of the PAFC bus. Because safety is a critical factor for consumer acceptance of new transportation-based technologies the study focuses on these issues.

2017-08-01

In any context, operation and management of transportation systems are key issues which may affect both life quality and economic development. In large urban agglomerations, an efficient public transportation system may help abate the negative externalities of private car use such as congestion, air and noise pollution, accident and fuel consumption, without excessively penalizing user travel times or zone accessibility. Thus, this study is conducted to appraise the Malaysian rural rail transit operation and management system, which are considered important as there are many issues and solution in integration of the services that need to be tackled more conscientiously. The purpose of this paper is to describe some of the most important issues on integration of services and rail transit system in Malaysian and how to solve or reduce these problems and conflicts. In this paper, it consists of the historical development of rail transit construction in Malaysia. This paper also attempts to identify the important issues related to rail transit services and integration in Malaysian rural rail operation and management system. Comparison is also conducted with other countries such as UK, France, and Japan. Finally, a critical analysis is presented in this paper by looking at the possible application for future Malaysian rail transit operation system and management, especially focusing on enhancing the quality of Malaysian rural rail transit. In conclusion, this paper is expected to successfully review and appraise the existing Malaysian rural rail transit operation and management system pertaining to issues & solution in integration. It is also hoped that reformation or transformation of present service delivery quality of the rail transit operation and management will enable Malaysia to succeed in transforming Malaysian transportation system to greater heights.

Alignment issues, correlation techniques and their assessment for a visible light imaging-based 3D printer quality control system

Quality control is critical to manufacturing. Frequently, techniques are used to define object conformity bounds, based on historical quality data. This paper considers techniques for bespoke and small batch jobs that are not statistical model based. These techniques also serve jobs where 100% validation is needed due to the mission or safety critical nature of particular parts. One issue with this type of system is alignment discrepancies between the generated model and the physical part. This paper discusses and evaluates techniques for characterizing and correcting alignment issues between the projected and perceived data sets to prevent errors attributable to misalignment.

Issues in Software System Safety: Polly Ann Smith Co. versus Ned I. Ludd

Holloway, C. Michael

2002-01-01

This paper is a work of fiction, but it is fiction with a very real purpose: to stimulate careful thought and friendly discussion about some questions for which thought is often careless and discussion is often unfriendly. To accomplish this purpose, the paper creates a fictional legal case. The most important issue in this fictional case is whether certain proffered expert testimony about software engineering for safety critical systems should be admitted. Resolving this issue requires deciding the extent to which current practices and research in software engineering, especially for safety-critical systems, can rightly be considered based on knowledge, rather than opinion.

Coker, David L; Kim, Young-Suk Grace

In this introduction to the special series "Critical Issues in the Understanding of Young Elementary School Students at Risk for Problems in Written Expression," we consider some of the contextual factors that have changed since a similar special issue was published in the Journal of Learning Disabilities in 2002. We also explore how the five articles included in this special series address the following important themes: early writing development, identification of students with writing difficulties, and effective interventions for struggling writers. In conclusion, we envision future directions to advance the field.

Rakich, J S; Feit, M D

2001-01-01

Public policy affects health and social services organizations. Senior management has a responsibility to prevent inappropriate demands of stakeholders from predominating and to influence the outcome of public policy to the benefit of their organization through the strategic issues management process. This article presents a public policy issue life cycle model, life-cycle stages and suggested strategies, paths issues can take in the life cycle, and factors that affect issue paths. An understanding of these dynamics can aid senior managers in shaping and changing public policy issues and lessening external environment threats to their organization.

Helmholtz's Kant revisited (Once more). The all-pervasive nature of Helmholtz's struggle with Kant's Anschauung.

PubMed

De Kock, Liesbet

2016-04-01

In this analysis, the classical problem of Hermann von Helmholtz's (1821-1894) Kantianism is explored from a particular vantage point, that to my knowledge, has not received the attention it deserves notwithstanding its possible key role in disentangling Helmholtz's relation to Kant's critical project. More particularly, we will focus on Helmholtz's critical engagement with Kant's concept of intuition [Anschauung] and (the related issue of) his dissatisfaction with Kant's doctrinal dualism. In doing so, it soon becomes clear that both (i) crucially mediated Helmholtz's idiosyncratic appropriation and criticism of (certain aspects of) Kant's critical project, and (ii) can be considered as a common denominator in a variety of issues that are usually addressed separately under the general header of (the problem of) Helmholtz's Kantianism. The perspective offered in this analysis can not only shed interesting new light on some interpretive issues that have become commonplace in discussions on Helmholtz's Kantianism, but also offers a particular way of connecting seemingly unrelated dimensions of Helmholtz's engagement with Kant's critical project (e.g. Helmholtz's views on causality and space). Furthermore, it amounts to the rather surprising conclusion that Helmholtz's most drastic revision of Kant's project pertains to his assumption of free will as a formal condition of experience and knowledge.

Using Critical Literacy to Explore Genetics and its Ethical, Legal, and Social Issues with In-Service Secondary Teachers

PubMed Central

Melançon, Megan E.; Kleine, Karynne L. M.

2010-01-01

The described interdisciplinary course helped a mixed population of in-service secondary English and biology teacher-participants increase their genetics content knowledge and awareness of Ethical, Legal, and Social Implications (ELSI) that arose from discoveries and practices associated with the Human Genome Project. This was accomplished by applying a critical literacy approach that allows people develop cognitive skills such that they are able to “read the world” (Wink, 2004). The approach is one that permits readers to go beyond the literal text to examine what is present as well as what is missing as it relates to issues of equity and fairness. Becoming critically literate enabled these teacher-participants to challenge the subtle attitudes, values, and beliefs conveyed by a range of written and oral texts. The teacher-participants in this course improved their critical literacy skills by actively reading, critically writing about, and using evidence to support their conclusions about issues arising from advances in human genetics. A biologist, a linguist, and an educator collaboratively designed and taught the course. The personalized focus on the integration of thoughtful reading and writing in this class enhanced the teacher-participants' (n = 16) professional and intellectual development and will potentially improve learning in their biology and English classrooms in the future.

Setting the standard: Medical Education's first 50 years.

By understanding its history, the medical education community gains insight into why it thinks and acts as it does. This piece provides a Foucauldian archaeological critical discourse analysis (CDA) of the journal Medical Education on the publication of its 50th Volume. This analysis draws upon critical social science perspectives to allow the examination of unstated assumptions that underpin and shape educational tools and practices. A Foucauldian form of CDA was utilised to examine the journal over its first half-century. This approach emphasises the importance of language, and the ways in which words used affect and are affected by educational practices and priorities. An iterative methodology was used to organise the very large dataset (12,000 articles). A distilled dataset, within which particular focus was placed on the editorial pieces in the journal, was analysed. A major finding was the diversity of the journal as a site that has permitted multiple - and sometimes contradictory - discursive trends to emerge. One particularly dominant discursive tension across the time span of the journal is that between a persistent drive for standardisation and a continued questioning of the desirability of standardisation. This tension was traced across three prominent areas of focus in the journal: objectivity and the nature of medical education knowledge; universality and local contexts, and the place of medical education between academia and the community. The journal has provided the medical education community with a place in which to both discuss practical pedagogical concerns and ponder conceptual and social issues affecting the medical education community. This dual nature of the journal brings together educators and researchers; it also gives particular focus to a major and rarely cited tension in medical education between the quest for objective standards and the limitations of standard measures. © 2015 John Wiley & Sons Ltd.

Physician satisfaction with a critical care clinical information system using a multimethod evaluation of usability.

Physician satisfaction with electronic medical records has often been poor. Usability has frequently been identified as a source for decreased satisfaction. While surveys can identify many issues, and are logistically easier to administer, they may miss issues identified using other methods This study sought to understand the level of physician satisfaction and usability issues associated with a critical care clinical information system (eCritical Alberta) implemented throughout the province of Alberta, Canada. All critical care attending physicians using the system were invited to participate in an online survey. Questions included components of the User Acceptance of Information Technology and Usability Questionnaire as well as free text feedback on system components. Physicians were also invited to participate in a think aloud test using simulated scenarios. The transcribed think aloud text and questionnaire were subjected to textual analysis. 82% of all eligible physicians completed the on-line survey (n = 61). Eight physicians were invited and seven completed the think aloud test. Overall satisfaction with the system was moderate. Usability was identified as a significant factor contributing to satisfaction. The major usability factors identified were system response time and layout. The think aloud component identified additional factors beyond those identified in the on-line survey. This study found a modestly high level of physician satisfaction with a province-wide clinical critical care information system. Usability continues to be a significant factor in physician satisfaction. Using multiple methods of evaluation can capture the benefits of a large sample size and deeper understanding of the issues.

To explore the methodological and ethical issues of conducting qualitative telephone interviews about personal or professional trauma with critical care nurses. The most common method for conducting interviews is face-to-face. However, there is evidence to support telephone interviewing on a variety of sensitive topics including post-traumatic stress disorder (PTSD). Qualitative telephone interviews can limit emotional distress because of the comfort experienced through virtual communication. Critical care nurses are at increased risk of developing PTSD due to the cumulative exposure to work-related stress in the intensive care unit. We explored the methodological and ethical issues of conducting qualitative telephone interviews, drawing on our experiences communicating with a group of critical care nurses. Qualitative research interviews with 27 critical care nurses. Fourteen of the nurses met the diagnostic criteria for PTSD; 13 did not and had scores consistent with high levels of resilience. This is a methodology paper on the authors' experiences of interviewing critical care nurses on sensitive topics via the telephone. The authors found that establishing rapport and connections with the participants and the therapeutic use of non-verbal communication were essential, and fostered trust and compassion. The ethical issues of this mode of communication include protecting the privacy and confidentiality associated with the disclosure of sensitive information, and minimising the risk of psychological harm to the researcher and participants. Qualitative telephone interviews are a valuable method of collecting information on sensitive topics. This paper explores a method of interviewing in the workplace. It will help inform interventions to promote healthy adaptation following trauma exposure in the intensive care unit.
