Despite reporting low levels of well-being, anorexia nervosa patients express temperament traits (e.g., extraversion and persistence) necessary for high levels of life satisfaction. Nevertheless, among individuals without eating disorders, a balanced organization of the flow of time, influences life satisfaction beyond temperamental dispositions. A balanced time perspective is defined as: high past positive, low past negative, high present hedonistic, low present fatalistic, and high future. We investigated differences in time perspective dimensions, personality traits, and life satisfaction between anorexia nervosa patients and matched controls. We also investigated if the personality traits and the outlook on time associated to positive levels of life satisfaction among controls also predicted anorexia patients' life satisfaction. Additionally, we investigated if time perspective dimensions predicted life satisfaction beyond personality traits among both patients and controls. A total of 88 anorexia nervosa patients from a clinic in the West of Sweden and 111 gender-age matched controls from a university in the West of Sweden participated in the Study. All participants responded to the Zimbardo Time Perspective Inventory, the Ten Item Personality Inventory, and the Temporal Satisfaction with Life Scale. A t -test showed that patients scored higher in the past negative, the present fatalistic, and the future dimensions, lower in the past positive and the present hedonistic dimensions, higher in conscientiousness, extraversion, and agreeableness, and lower in life satisfaction. Regression analyses showed that life satisfaction was predicted by openness to experience and emotional stability for controls and by emotional stability among patients. When time dimensions were entered in the regression, emotional stability and the past negative and past positive time dimensions predicted life satisfaction among controls, but only the past positive and present hedonistic time dimensions predicted life satisfaction among patients. Anorexia patients were less satisfied with life despite being more conscientious, social, and agreeable than controls. Moreover, compared to controls, patients had an unbalanced time perspective: a dark view of the past (i.e., high past negative), a restrained present (i.e., low present hedonistic) and an apocalyptic view of the future (i.e., high present fatalistic). It is plausible to suggest that, therapeutic interventions should focus on empowering patients to cultivate a sentimental and positive view of the past (i.e., high past positive) and the desire to experience pleasure without concern for future consequences (i.e., high present hedonistic) so that they can make self-directed and flexible choices for their own well-being. Such interventions might have effects on life satisfaction beyond the patients' temperamental disposition.

Most studies of emotion abilities in disruptive children focus on emotion expression recognition. This study compared 74 children aged 4-8 years with ODD to 45 comparison children (33 healthy; 12 with an anxiety disorder) on behaviourally assessed measures of emotion perception, emotion perspective-taking, knowledge of emotions causes and understanding ambivalent emotions and on parent-reported cognitive and affective empathy. Adjusting for child's sex, age and expressive language ODD children showed a paucity in attributing causes to emotions but no other deficits relative to the comparison groups. ODD boys with high levels of callous-unemotional traits (CU) (n = 22) showed deficits relative to low CU ODD boys (n = 25) in emotion perspective-taking and in understanding ambivalent emotions. Low CU ODD boys did not differ from the healthy typically developing boys (n = 12). Impairments in emotion perceptive-taking and understanding mixed emotions in ODD boys are associated with the presence of a high level of CU.

Questions of time and affect: a person’s affectivity profile, time perspective, and well-being

PubMed Central

Sailer, Uta; Nima, Ali Al; Archer, Trevor

2016-01-01

Background. A “balanced” time perspective has been suggested to have a positive influence on well-being: a sentimental and positive view of the past (high Past Positive), a less pessimistic attitude toward the past (low Past Negative), the desire of experiencing pleasure with slight concern for future consequences (high Present Hedonistic), a less fatalistic and hopeless view of the future (low Present Fatalistic), and the ability to find reward in achieving specific long-term goals (high Future). We used the affective profiles model (i.e., combinations of individuals’ experience of high/low positive/negative affectivity) to investigate differences between individuals in time perspective dimensions and to investigate if the influence of time perspective dimensions on well-being was moderated by the individual’s type of profile. Method. Participants (N = 720) answered to the Positive Affect Negative Affect Schedule, the Zimbardo Time Perspective Inventory and two measures of well-being: the Temporal Satisfaction with Life Scale and Ryff’s Scales of Psychological Well-Being-short version. A Multivariate Analysis of Variance (MANOVA) was conducted to identify differences in time perspective dimensions and well-being among individuals with distinct affective profiles. Four structural equation models (SEM) were used to investigate which time perspective dimensions predicted well-being for individuals in each profile. Results. Comparisons between individuals at the extreme of the affective profiles model suggested that individuals with a self-fulfilling profile (high positive/low negative affect) were characterized by a “balanced” time perspective and higher well-being compared to individuals with a self-destructive profile (low positive/high negative affect). However, a different pattern emerged when individuals who differed in one affect dimension but matched in the other were compared to each other. For instance, decreases in the past negative time perspective dimension lead to high positive affect when negative affect is high (i.e., self-destructive vs. high affective) but to low negative affect when positive affect was high (i.e., high affective vs. self-fulfilling). The moderation analyses showed, for example, that for individuals with a self-destructive profile, psychological well-being was significantly predicted by the past negative, present fatalistic and future time perspectives. Among individuals with a high affective or a self-fulfilling profile, psychological well-being was significantly predicted by the present fatalistic dimension. Conclusions. The interactions found here go beyond the postulation of a “balanced” time perspective being the only way to promote well-being. Instead, we present a more person-centered approach to achieve higher levels of emotional, cognitive, and psychological well-being. PMID:27019786

2017-07-01

Clear patterns emerged and are summarised on conditions for success in integrating a gender equality perspective across organisational programmes and culture. In short, organisations should consider five key 'ingredients' when designing their approach to integrating a gender equality perspective: (1) have a clear vision of success with measurable indicators; (2) have high-level, consistent, visible support; (3) take an intentional approach deeply rooted in the organisational culture and competencies; (4) ensure accountability at all levels and (5) invest both financial and technical resources. A vibrant community exists in virtually every region of the world of highly experienced gender equality experts that can support organisations on this path. Late adopters of integrating a gender equality perspective can benefit from decades of practice and a robust evidence base which has shifted focus among development organisations from asking 'why' addressing gender inequalities is important to learning 'how' to most effectively do this in programmes, policies, research and organisational culture while building a strong results framework.

Trainee perspectives on postdoctoral recruitment in clinical neuropsychology: reflections on commentaries by Bodin and Grote (2016) and Nelson et al. (2016).

2018-01-01

The aim of the current invited paper is to provide the trainees' perspective on recent commentaries on recruitment for postdoctoral fellowship in clinical neuropsychology. The current system of recruitment includes both a match and non-match process and has been problematic for trainees and training programs alike. The author team completed a non-systematic review of previously published commentaries on the current state of postdoctoral fellowship recruitment, which are briefly summarized in the current paper. The trainee perspective is addressed using both survey data and anecdotal experiences of the authors. Trainees report high levels of dissatisfaction with the current dual recruitment system; however, there is no clear preference from trainees for either a match or non-match system. Trainees from both recruitment systems report high levels of satisfaction with their training experience. It seems that either a match or non-match approach, if it led to a unified system, would improve trainee satisfaction.

Extant research on high-performance work systems (HPWSs) has primarily examined the effects of HPWSs on establishment or firm-level performance from a management perspective in manufacturing settings. The current study extends this literature by differentiating management and employee perspectives of HPWSs and examining how the two perspectives relate to employee individual performance in the service context. Data collected in three phases from multiple sources involving 292 managers, 830 employees, and 1,772 customers of 91 bank branches revealed significant differences between management and employee perspectives of HPWSs. There were also significant differences in employee perspectives of HPWSs among employees of different employment statuses and among employees of the same status. Further, employee perspective of HPWSs was positively related to individual general service performance through the mediation of employee human capital and perceived organizational support and was positively related to individual knowledge-intensive service performance through the mediation of employee human capital and psychological empowerment. At the same time, management perspective of HPWSs was related to employee human capital and both types of service performance. Finally, a branch's overall knowledge-intensive service performance was positively associated with customer overall satisfaction with the branch's service. (c) 2009 APA, all rights reserved.

How Do High-Performance Work Systems Affect Individual Outcomes: A Multilevel Perspective.

2018-01-01

Research on high-performance work systems (HPWS) has suggested that a potential disconnection may exist between organizational-level HPWS and employee experienced HPWS. However, few studies have identified factors that are implied within such a relationship. Using a sample of 397 employees, 84 line managers, and 21 HR executives in China, we examined whether line managers' goal congruence can reduce the difference between organizational-level HPWS and employee experienced HPWS. Furthermore, this study also theorized and tested organization-based self-esteem (OBSE) as a mediator in the associations between employee experienced HPWS and job performance and job satisfaction. Using multilevel analyses, we found that line managers' goal congruence strengthened the relationship between organizational-level HPWS and employee experienced HPWS, such that the relationship was significant and positive when line managers' goal congruence was high, but a non-significant relationship when line managers' goal congruence was low. Moreover, employee experienced HPWS indirectly affected job performance and job satisfaction through the mechanism of OBSE beyond social exchange perspective.

Scaled CMOS Reliability and Considerations for Spacecraft Systems: Bottom-Up and Top-Down Perspective

NASA Technical Reports Server (NTRS)

White, Mark

2012-01-01

New space missions will increasingly rely on more advanced technologies because of system requirements for higher performance, particularly in instruments and high-speed processing. Component-level reliability challenges with scaled CMOS in spacecraft systems from a bottom-up perspective have been presented. Fundamental Front-end and Back-end processing reliability issues with more aggressively scaled parts have been discussed. Effective thermal management from system-level to the componentlevel (top-down) is a key element in overall design of reliable systems. Thermal management in space systems must consider a wide range of issues, including thermal loading of many different components, and frequent temperature cycling of some systems. Both perspectives (top-down and bottom-up) play a large role in robust, reliable spacecraft system design.

Treating elevated cholesterol levels: the great Satan in perspective.

Gibaldi, M; Kradjan, W

The purpose of this review is to provide perspective on the developments leading to the recognition of high cholesterol levels as a risk factor for coronary heart disease (CHD). Another objective is to consider the unfolding controversies regarding the relative value of cholesterol-lowering drug therapy in primary and secondary prevention. Should physicians use lipid-lowering drugs to treat patients with elevated cholesterol levels but no clinical evidence of coronary disease, or limit intervention to patients with a previous history of angina, coronary angioplasty, coronary artery bypass surgery, or myocardial infarction? This review finds inadequate data to support a recommendation for screening large populations for the presence of elevated cholesterol levels or for primary prevention in those known to have high cholesterol. On the other hand, there is mounting evidence to support vigorous intervention in those with known coronary disease. Further study is needed to determine whether a subset of patients with one or more well-defined risk factors would benefit from primary prevention.

Instantiating the multiple levels of analysis perspective in a program of study on externalizing behavior

Beauchaine, Theodore P.; Gatzke-Kopp, Lisa M.

2014-01-01

During the last quarter century, developmental psychopathology has become increasingly inclusive and now spans disciplines ranging from psychiatric genetics to primary prevention. As a result, developmental psychopathologists have extended traditional diathesis–stress and transactional models to include causal processes at and across all relevant levels of analysis. Such research is embodied in what is known as the multiple levels of analysis perspective. We describe how multiple levels of analysis research has informed our current thinking about antisocial and borderline personality development among trait impulsive and therefore vulnerable individuals. Our approach extends the multiple levels of analysis perspective beyond simple Biology × Environment interactions by evaluating impulsivity across physiological systems (genetic, autonomic, hormonal, neural), psychological constructs (social, affective, motivational), developmental epochs (preschool, middle childhood, adolescence, adulthood), sexes (male, female), and methods of inquiry (self-report, informant report, treatment outcome, cardiovascular, electrophysiological, neuroimaging). By conducting our research using any and all available methods across these levels of analysis, we have arrived at a developmental model of trait impulsivity that we believe confers a greater understanding of this highly heritable trait and captures at least some heterogeneity in key behavioral outcomes, including delinquency and suicide.

Instructor perspectives of multiple-choice questions in summative assessment for novice programmers

NASA Astrophysics Data System (ADS)

Shuhidan, Shuhaida; Hamilton, Margaret; D'Souza, Daryl

2010-09-01

Learning to program is known to be difficult for novices. High attrition and high failure rates in foundation-level programming courses undertaken at tertiary level in Computer Science programs, are commonly reported. A common approach to evaluating novice programming ability is through a combination of formative and summative assessments, with the latter typically represented by a final examination. Preparation of such assessment is driven by instructor perceptions of student learning of programming concepts. This in turn may yield instructor perspectives of summative assessment that do not necessarily correlate with student expectations or abilities. In this article, we present results of our study around instructor perspectives of summative assessment for novice programmers. Both quantitative and qualitative data have been obtained via survey responses from programming instructors with varying teaching experience, and from novice student responses to targeted examination questions. Our findings highlight that most of the instructors believed that summative assessment is, and is meant to be, a valid measure of a student's ability to program. Most instructors further believed that Multiple-choice Questions (MCQs) provide a means of testing a low level of understanding, and a few added qualitative comments to suggest that MCQs are easy questions, and others refused to use them at all. There was no agreement around the proposition that if a question was designed to test a low level of skill, or a low level in a hierarchy of a body of knowledge, that such a question should or would be found to be easy by the student. To aid our analysis of assessment questions, we introduced four measures: Syntax Knowledge; Semantic Knowledge; Problem Solving Skill and the Level of Difficulty of the Problem. We applied these measures to selected examination questions, and have identified gaps between the instructor perspectives of what is considered to be an easy question and also in what is required to be assessed to determine whether students have achieved the goals of their course.

Strengthening and toughening metallic glasses: The elastic perspectives and opportunities

NASA Astrophysics Data System (ADS)

Liu, Z. Q.; Zhang, Z. F.

2014-04-01

There exist general conflicts between strength and toughness in crystalline engineering materials, and various strengthening and toughening strategies have been developed from the dislocation motion perspectives. Metallic glasses (MGs) have demonstrated great potentials owing to their unique properties; however, their structural applications are strictly limited. One of the key problems is that the traditional strengthening and toughening strategies and mechanisms are not applicable in MGs due to the absence of dislocations and crystalline microstructures. Here, we show that the strength and toughness, or equivalently the shear modulus and Poisson's ratio, are invariably mutually exclusive in MGs. Accordingly, the MGs can be categorized into four groups with different levels of integrated mechanical properties. It is further revealed that the conflicts originate fundamentally from the atomic bonding structures and the levels of strength-toughness combinations are indeed dominated by the bulk modulus. Moreover, we propose novel strategies for optimizing the mechanical properties of MGs from the elastic perspectives. We emphasize the significance of developing high bulk modulus MGs to achieve simultaneously both high strength and good toughness and highlight the elastic opportunities for strengthening and toughening materials.

Psychosis-proneness and neural correlates of self-inhibition in theory of mind.

PubMed

van der Meer, Lisette; Groenewold, Nynke A; Pijnenborg, Marieke; Aleman, André

2013-01-01

Impaired Theory of Mind (ToM) has been repeatedly reported as a feature of psychotic disorders. ToM is crucial in social interactions and for the development of social behavior. It has been suggested that reasoning about the belief of others, requires inhibition of the self-perspective. We investigated the neural correlates of self-inhibition in nineteen low psychosis prone (PP) and eighteen high PP subjects presenting with subclinical features. High PP subjects have a more than tenfold increased risk of developing a schizophrenia-spectrum disorder. Brain activation was measured with functional Magnetic Resonance Imaging during a ToM task differentiating between self-perspective inhibition and belief reasoning. Furthermore, to test underlying inhibitory mechanisms, we included a stop-signal task. We predicted worse behavioral performance for high compared to low PP subjects on both tasks. Moreover, based on previous neuroimaging results, different activation patterns were expected in the inferior frontal gyrus (IFG) in high versus low PP subjects in self-perspective inhibition and simple response inhibition. Results showed increased activation in left IFG during self-perspective inhibition, but not during simple response inhibition, for high PP subjects as compared to low PP subjects. High and low PP subjects showed equal behavioral performance. The results suggest that at a neural level, high PP subjects need more resources for inhibiting the self-perspective, but not for simple motor response inhibition, to equal the performance of low PP subjects. This may reflect a compensatory mechanism, which may no longer be available for patients with schizophrenia-spectrum disorders resulting in ToM impairments.

Analyses were conducted for nalmefene's licensed population: adults with both alcohol dependence and high or very high drinking-risk levels (DRLs) who do not require immediate detoxification and who have high or very high DRLs after initial assessment. The main outcome measure was cost per quality-adjusted life-year (QALY) gained as assessed from a UK societal perspective. Alcohol-attributable productivity loss, crime and health events occurring at different levels of alcohol consumption were taken from published risk-relation studies. Health-related and societal costs were drawn from public data and the literature. Data on the treatment effect, as well as baseline characteristics of the modelled population and utilities, came from three pivotal phase 3 trials of nalmefene. Nalmefene plus psychosocial support was dominant compared with psychosocial intervention alone, resulting in QALYs gained and reduced societal costs. Sensitivity analyses showed that this conclusion was robust. Nalmefene plus psychosocial support led to per-patient reduced costs of £3324 and £2483, due to reduced productivity losses and crime events, respectively. Nalmefene is cost effective from a UK societal perspective, resulting in greater QALY gains and lower costs compared with psychosocial support alone. Nalmefene demonstrates considerable public benefits by reducing alcohol-attributable productivity losses and crime events in adults with both alcohol dependence and high or very high DRLs who do not require immediate detoxification and who have high or very high DRLs after initial assessment.

Working together versus working autonomously: a new power-dependence perspective on the individual-level of analysis.

PubMed

de Jong, Simon B

2014-01-01

Recent studies have indicated that it is important to investigate the interaction between task interdependence and task autonomy because this interaction can affect team effectiveness. However, only a limited number of studies have been conducted and those studies focused solely on the team level of analysis. Moreover, there has also been a dearth of theoretical development. Therefore, this study develops and tests an alternative theoretical perspective in an attempt to understand if, and if so why, this interaction is important at the individual level of analysis. Based on interdependence theory and power-dependence theory, we expected that highly task-interdependent individuals who reported high task autonomy would be more powerful and better performers. In contrast, we expected that similarly high task-interdependent individuals who reported less task autonomy would be less powerful and would be weaker performers. These expectations were supported by multi-level and bootstrapping analyses performed on a multi-source dataset (self-, peer-, manager-ratings) comprised of 182 employees drawn from 37 teams. More specifically, the interaction between task interdependence and task autonomy was γ =.128, p <.05 for power and γ =.166, p <.05 for individual performance. The 95% bootstrap interval ranged from .0038 to .0686.

Time perspective in hereditary cancer: psychometric properties of a short form of the Zimbardo Time Perspective Inventory in a community and clinical sample.

2010-10-01

We aimed to assess the psychometric properties of a 25-item short form of the Zimbardo Time Perspective Inventory in a community sample (N = 276) and in individuals with a strong family history of cancer, considering genetic testing for cancer risk (N = 338). In the community sample, individuals with high past-negative or present-fatalistic scores had higher levels of distress, as measured by depression, anxiety, and aggression. Similarly, in the patient sample, past-negative time perspective was positively correlated with distress, uncertainty, and postdecision regret when making a decision about genetic testing. Past-negative-oriented individuals were also more likely to be undecided about, or against, genetic testing. Hedonism was associated with being less likely to read the educational materials they received at their clinic, and fatalism was associated with having lower knowledge levels about genetic testing. The assessment of time perspective in individuals at increased risk of cancer can provide valuable clinical insights. However, further investigation of the psychometric properties of the short form of this scale is warranted, as it did not meet the currently accepted criteria for psychometric validation studies.

Water levels shape fishing participation in flood-control reservoirs

USGS Publications Warehouse

Miranda, Leandro E.; Meals, K. O.

2013-01-01

We examined the relationship between fishing effort (hours fished) and average March–May water level in 3 flood control reservoirs in Mississippi. Fishing effort increased as water level rose, peaked at intermediate water levels, and decreased at high water levels. We suggest that the observed arched-shaped relationship is driven by the shifting influence of fishability (adequacy of the fishing circumstances from an angler's perspective) and catch rate along a water level continuum. Fishability reduces fishing effort during low water, despite the potential for higher catch rates. Conversely, reduced catch rates and fishability at high water also curtail effort. Thus, both high and low water levels seem to discourage fishing effort, whereas anglers seem to favor intermediate water levels. Our results have implications for water level management in reservoirs with large water level fluctuations.

Bayesian Dose-Response Modeling in Sparse Data

NASA Astrophysics Data System (ADS)

Kim, Steven B.

This book discusses Bayesian dose-response modeling in small samples applied to two different settings. The first setting is early phase clinical trials, and the second setting is toxicology studies in cancer risk assessment. In early phase clinical trials, experimental units are humans who are actual patients. Prior to a clinical trial, opinions from multiple subject area experts are generally more informative than the opinion of a single expert, but we may face a dilemma when they have disagreeing prior opinions. In this regard, we consider compromising the disagreement and compare two different approaches for making a decision. In addition to combining multiple opinions, we also address balancing two levels of ethics in early phase clinical trials. The first level is individual-level ethics which reflects the perspective of trial participants. The second level is population-level ethics which reflects the perspective of future patients. We extensively compare two existing statistical methods which focus on each perspective and propose a new method which balances the two conflicting perspectives. In toxicology studies, experimental units are living animals. Here we focus on a potential non-monotonic dose-response relationship which is known as hormesis. Briefly, hormesis is a phenomenon which can be characterized by a beneficial effect at low doses and a harmful effect at high doses. In cancer risk assessments, the estimation of a parameter, which is known as a benchmark dose, can be highly sensitive to a class of assumptions, monotonicity or hormesis. In this regard, we propose a robust approach which considers both monotonicity and hormesis as a possibility. In addition, We discuss statistical hypothesis testing for hormesis and consider various experimental designs for detecting hormesis based on Bayesian decision theory. Past experiments have not been optimally designed for testing for hormesis, and some Bayesian optimal designs may not be optimal under a wrong parametric assumption. In this regard, we consider a robust experimental design which does not require any parametric assumption.

Visual perspective taking impairment in children with autistic spectrum disorder.

PubMed

Hamilton, Antonia F de C; Brindley, Rachel; Frith, Uta

2009-10-01

Evidence from typical development and neuroimaging studies suggests that level 2 visual perspective taking - the knowledge that different people may see the same thing differently at the same time - is a mentalising task. Thus, we would expect children with autism, who fail typical mentalising tasks like false belief, to perform poorly on level 2 visual perspective taking as well. However, prior data on this issue are inconclusive. We re-examined this question, testing a group of 23 young autistic children, aged around 8years with a verbal mental age of around 4years and three groups of typical children (n=60) ranging in age from 4 to 8years on a level 2 visual perspective task and a closely matched mental rotation task. The results demonstrate that autistic children have difficulty with visual perspective taking compared to a task requiring mental rotation, relative to typical children. Furthermore, performance on the level 2 visual perspective taking task correlated with theory of mind performance. These findings resolve discrepancies in previous studies of visual perspective taking in autism, and demonstrate that level 2 visual perspective taking is a mentalising task.

Abstract Background. As the proportion of the population aged 80 and over accelerates, so does the value of understanding the processes of aging well. The purposes of this article are to: (a) review contemporary theoretical and conceptual perspectives on aging well, (b) describe indicators of aging well that reflect key concepts and perspectives as assessed in the Women’s Health Initiative (WHI) and (c) characterize the status of aging among women aged 80 and older using data obtained from WHI participants at the WHI Extension 2 follow-up. Methods. Data from the Lifestyle Questionnaire, which was administered from 2011 to 2012 during the WHI Follow-up Study (Extension 2), were analyzed to provide a profile of the WHI cohort with respect to aging well. Results. Data revealed substantial diversity in the cohort with respect to the various measures of aging well. Although many reported physical functioning levels consistent with disability, most rated their health as good or better. Most reported moderately high levels of resilience, self-control, and self-mastery but lower levels of environmental mastery. Finally, the cohort reported high levels of optimal aging as reflected by their high levels of emotional well-being and moderately high levels of life satisfaction and social support, but more modest levels of personal growth and purpose in life. Conclusions. The wide range of some dimensions of aging well suggest that further examination of predictors of positive coping and resilience in the face of aging-related disability could identify opportunities to support and facilitate aging well among U.S. women.

Strengthening and toughening metallic glasses: The elastic perspectives and opportunities

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

Liu, Z. Q.; Zhang, Z. F., E-mail: zhfzhang@imr.ac.cn

2014-04-28

There exist general conflicts between strength and toughness in crystalline engineering materials, and various strengthening and toughening strategies have been developed from the dislocation motion perspectives. Metallic glasses (MGs) have demonstrated great potentials owing to their unique properties; however, their structural applications are strictly limited. One of the key problems is that the traditional strengthening and toughening strategies and mechanisms are not applicable in MGs due to the absence of dislocations and crystalline microstructures. Here, we show that the strength and toughness, or equivalently the shear modulus and Poisson's ratio, are invariably mutually exclusive in MGs. Accordingly, the MGs canmore » be categorized into four groups with different levels of integrated mechanical properties. It is further revealed that the conflicts originate fundamentally from the atomic bonding structures and the levels of strength-toughness combinations are indeed dominated by the bulk modulus. Moreover, we propose novel strategies for optimizing the mechanical properties of MGs from the elastic perspectives. We emphasize the significance of developing high bulk modulus MGs to achieve simultaneously both high strength and good toughness and highlight the elastic opportunities for strengthening and toughening materials.« less

Efficient high-quality volume rendering of SPH data.

PubMed

Fraedrich, Roland; Auer, Stefan; Westermann, Rüdiger

2010-01-01

High quality volume rendering of SPH data requires a complex order-dependent resampling of particle quantities along the view rays. In this paper we present an efficient approach to perform this task using a novel view-space discretization of the simulation domain. Our method draws upon recent work on GPU-based particle voxelization for the efficient resampling of particles into uniform grids. We propose a new technique that leverages a perspective grid to adaptively discretize the view-volume, giving rise to a continuous level-of-detail sampling structure and reducing memory requirements compared to a uniform grid. In combination with a level-of-detail representation of the particle set, the perspective grid allows effectively reducing the amount of primitives to be processed at run-time. We demonstrate the quality and performance of our method for the rendering of fluid and gas dynamics SPH simulations consisting of many millions of particles.

Patient perspectives on virtual reality-based rehabilitation after knee surgery: Importance of level of difficulty.

Lee, Minyoung; Suh, Dongwon; Son, Jaebum; Kim, Jungjin; Eun, Seon-Deok; Yoon, BumChul

2016-01-01

This article explored the perspectives of 25 patients regarding virtual reality (VR)-based rehabilitation following knee surgery and identified the important factors that allowed patients to immerse themselves in rehabilitation. Qualitative analysis of data collected via open-ended questionnaire and quantitative analysis of data from physical assessments and surveys were conducted. In the open-ended questionnaire, the majority of participants mentioned level of difficulty as the most common reason for selecting both the most and the least immersive exercise programs. Quantitative analysis showed that participants experienced a high level of flow (3.9 +/- 0.3 out of 5.0) and a high rate of expectation of therapeutic effect (96%) and intention of exercise adherence (96%). Further, participants with more severe pain or physical dysfunction tended to have more positive experiences (e.g., Difficulty-Skill Balance, Clear Goals, and Transformation of Time), leading to high levels of flow during VR-based rehabilitation. In conclusion, VR-based games are potentially acceptable as a motivational rehabilitation tool for patients following knee surgery. However, to best meet patients' needs, it might be useful to equip a VR program with varied levels of difficulty, taking into account the severity of the individual's knee injury. Additionally, severe pain or physical dysfunction might act as an indication rather than a contraindication for VR-based rehabilitation.

A Statistical Perspective on Highly Accelerated Testing

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

Thomas, Edward V.

Highly accelerated life testing has been heavily promoted at Sandia (and elsewhere) as a means to rapidly identify product weaknesses caused by flaws in the product's design or manufacturing process. During product development, a small number of units are forced to fail at high stress. The failed units are then examined to determine the root causes of failure. The identification of the root causes of product failures exposed by highly accelerated life testing can instigate changes to the product's design and/or manufacturing process that result in a product with increased reliability. It is widely viewed that this qualitative use ofmore » highly accelerated life testing (often associated with the acronym HALT) can be useful. However, highly accelerated life testing has also been proposed as a quantitative means for "demonstrating" the reliability of a product where unreliability is associated with loss of margin via an identified and dominating failure mechanism. It is assumed that the dominant failure mechanism can be accelerated by changing the level of a stress factor that is assumed to be related to the dominant failure mode. In extreme cases, a minimal number of units (often from a pre-production lot) are subjected to a single highly accelerated stress relative to normal use. If no (or, sufficiently few) units fail at this high stress level, some might claim that a certain level of reliability has been demonstrated (relative to normal use conditions). Underlying this claim are assumptions regarding the level of knowledge associated with the relationship between the stress level and the probability of failure. The primary purpose of this document is to discuss (from a statistical perspective) the efficacy of using accelerated life testing protocols (and, in particular, "highly accelerated" protocols) to make quantitative inferences concerning the performance of a product (e.g., reliability) when in fact there is lack-of-knowledge and uncertainty concerning the assumed relationship between the stress level and performance. In addition, this document contains recommendations for conducting more informative accelerated tests.« less

Level-2 perspectives computed quickly and spontaneously: Evidence from eight- to 9.5-year-old children.

2017-11-01

It has been widely assumed that computing how a scene looks from another perspective (level-2 perspective taking, PT) is an effortful process, as opposed to the automatic capacity of tracking visual access to objects (level-1 PT). Recently, adults have been found to compute both forms of visual perspectives in a quick but context-sensitive way, indicating that the two functions share more features than previously assumed. However, the developmental literature still shows the dissociation between automatic level-1 and effortful level-2 PT. In the current paper, we report an experiment showing that in a minimally social situation, participating in a number verification task with an adult confederate, eight- to 9.5-year-old children demonstrate similar online level-2 PT capacities as adults. Future studies need to address whether online PT shows selectivity in children as well and develop paradigms that are adequate to test preschoolers' online level-2 PT abilities. Statement of Contribution What is already known on this subject? Adults can access how objects appear to others (level-2 perspective) spontaneously and online Online level-1, but not level-2 perspective taking (PT) has been documented in school-aged children What the present study adds? Eight- to 9.5-year-olds performed a number verification task with a confederate who had the same task Children showed similar perspective interference as adults, indicating spontaneous level-2 PT Not only agent-object relations but also object appearances are computed online by eight- to 9.5-year-olds. © 2017 The British Psychological Society.

The association between time perspective and alcohol consumption in university students: cross-sectional study.

PubMed

Beenstock, Jane; Adams, Jean; White, Martin

2011-08-01

Heavy alcohol consumption is associated with significant morbidity and mortality. Levels of alcohol consumption among students and young people are particularly high. Time perspective describes the varying value individuals place on outcomes in the present and future. In general, it has been found that individuals prefer to receive a gain today rather than in the future. There is evidence that time perspective is associated with addictive health behaviours, including alcoholism and cigarette smoking, but less evidence of its association with non-addictive, but hazardous, levels of alcohol consumption. The objective was to determine if there is an association between time perspective and hazardous alcohol consumption. A cross-sectional survey using a self-completion questionnaire was administered to willing undergraduate students attending a convenience sample of lectures in two university faculties. Hazardous alcohol consumption was defined as a score of ≥8 on the Alcohol Use Disorders Identification Test (AUDIT) and time perspective was measured using the Consideration of Future Consequences Scale (CFCS). Participants were 322 undergraduate university students in two faculties at a university in Northern England, UK. Hazardous alcohol consumption was reported by 264 (82%) respondents. After controlling for potential confounding by socio-demographic variables, greater consideration of future consequences was associated with lower odds of reporting hazardous drinking [odds ratio = 0.28; 95% confidence interval 0.15-0.54]. Interventions aimed at increasing future orientated time perspective may be effective in decreasing hazardous alcohol consumption in students.

The student perspective of high school laboratory experiences

NASA Astrophysics Data System (ADS)

Lambert, R. Mitch

High school science laboratory experiences are an accepted teaching practice across the nation despite a lack of research evidence to support them. The purpose of this study was to examine the perspective of students---stakeholders often ignored---on these experiences. Insight into the students' perspective was explored progressively using a grounded theory methodology. Field observations of science classrooms led to an open-ended survey of high school science students, garnering 665 responses. Twelve student interviews then focused on the data and questions evolving from the survey. The student perspective on laboratory experiences revealed varied information based on individual experience. Concurrent analysis of the data revealed that although most students like (348/665) or sometimes like (270/665) these experiences, some consistent factors yielded negative experiences and prompted suggestions for improvement. The category of responses that emerged as the core idea focused on student understanding of the experience. Students desire to understand the why do, the how to, and the what it means of laboratory experiences. Lacking any one of these, the experience loses educational value for them. This single recurring theme crossed the boundaries of age, level in school, gender, and even the student view of lab experiences as positive or negative. This study suggests reflection on the current laboratory activities in which science teachers engage their students. Is the activity appropriate (as opposed to being merely a favorite), does it encourage learning, does it fit, does it operate at the appropriate level of inquiry, and finally what can science teachers do to integrate these activities into the classroom curriculum more effectively? Simply stated, what can teachers do so that students understand what to do, what's the point, and how that point fits into what they are learning outside the laboratory?

Villatte, Matthieu; Monestès, Jean-Louis; McHugh, Louise; Freixa i Baqué, Esteve; Loas, Gwenolé

2010-06-01

Impaired ability of identifying mental states is a characteristic of schizophrenia spectrum disorders. In particular, people suffering from this illness tend to fail at attributing a belief to another, which has been linked to difficulties in changing interpersonal perspective. Following the view of Relational Frame Theory on perspective-taking skills, the current study aimed at examining the involvement of social anhedonia, one of the frequent features of schizophrenia, in the development of deficits in reversing the I-YOU relation (i.e., adopting the perspective of another). A task consisting of attributing a belief to another or to the self was employed with 30 non-clinical participants with a high level of social anhedonia and with 15 patients diagnosed with schizophrenia. In comparison to two control groups, both experimental groups showed significant poorer performance when adopting the perspective of another. These results constitute important indications to target specific relational repertoires when attempting to remediate impairments in mental states attribution linked to schizophrenia.

Clinical and Insurance Perspectives on Intermediate Levels of Care in Psychiatry.

PubMed

Plakun, Eric M

2018-03-01

This column compares a clinical perspective on the continuum of care for mental health and substance use disorders with a different perspective derived from publicly available insurance company documents and experience dealing with managed care utilization reviewers. The latter perspective tends to determine the need for access to levels of care based on the need for crisis stabilization, whereas the generally accepted clinical standard is more nuanced than the need for crisis stabilization alone. The column proposes that this discrepancy in perspectives makes a substantial contribution to disagreements between treating clinicians, such as therapists, and insurance utilization reviewers concerning the medical necessity of various requested levels of care.

BioVLAB-mCpG-SNP-EXPRESS: A system for multi-level and multi-perspective analysis and exploration of DNA methylation, sequence variation (SNPs), and gene expression from multi-omics data.

Measuring gene expression, DNA sequence variation, and DNA methylation status is routinely done using high throughput sequencing technologies. To analyze such multi-omics data and explore relationships, reliable bioinformatics systems are much needed. Existing systems are either for exploring curated data or for processing omics data in the form of a library such as R. Thus scientists have much difficulty in investigating relationships among gene expression, DNA sequence variation, and DNA methylation using multi-omics data. In this study, we report a system called BioVLAB-mCpG-SNP-EXPRESS for the integrated analysis of DNA methylation, sequence variation (SNPs), and gene expression for distinguishing cellular phenotypes at the pairwise and multiple phenotype levels. The system can be deployed on either the Amazon cloud or a publicly available high-performance computing node, and the data analysis and exploration of the analysis result can be conveniently done using a web-based interface. In order to alleviate analysis complexity, all the process are fully automated, and graphical workflow system is integrated to represent real-time analysis progression. The BioVLAB-mCpG-SNP-EXPRESS system works in three stages. First, it processes and analyzes multi-omics data as input in the form of the raw data, i.e., FastQ files. Second, various integrated analyses such as methylation vs. gene expression and mutation vs. methylation are performed. Finally, the analysis result can be explored in a number of ways through a web interface for the multi-level, multi-perspective exploration. Multi-level interpretation can be done by either gene, gene set, pathway or network level and multi-perspective exploration can be explored from either gene expression, DNA methylation, sequence variation, or their relationship perspective. The utility of the system is demonstrated by performing analysis of phenotypically distinct 30 breast cancer cell line data set.

Emerging adulthood and the perception of parental depression.

PubMed

Kaimal, Girija; Beardslee, William R

2010-09-01

Few studies have examined children's perceptions of parental depression. This study was a qualitative analysis of the changes in the perception of parental depression between the ages of 17 and 19 years. Archived interview narratives of 16 respondents from a longitudinal, preventive intervention study of depression in families were analyzed. The respondents were purposefully selected to represent both genders as well as higher and lower levels of family adversity. The perceptions of parental depression were found to fall into three categories: self-oriented perspectives (resistance and negativity), ambivalent perspectives, and, other-oriented perspectives (acceptance and compassion). Over time, respondents from the high-adversity families showed shifts from self-orientation to other-orientation, whereas the perspectives of respondents from low-adversity families remained unchanged. Some respondents with depression in both parents and/or siblings revealed changes in perception toward one parent but no change toward other family members with depression.

Medical Judgments Across the Range of Reported Pain Severity: Clinician and Lay Perspectives.

Tait, Raymond C; Chibnall, John T; House, Kylie; Biehl, Joann

2016-07-01

While increasing evidence suggests that observers discount high-severity chronic pain, factors that occasion such discounting are poorly understood, particularly regarding health provider vs lay perspectives. This study examined the effects of supporting medical evidence and comorbid psychological distress (pain behavior) on medical student and lay clinical judgments of increasingly severe patient pain reports. In a 2 × 2 × 2 × (7) mixed between- and within-subject design, participants (medical students vs lay) made clinical judgments after reading vignettes describing a hypothetical patient that varied in levels of medical evidence and pain behavior (low vs high) and pain severity (4/10-10/10). Fourth-year medical students (N = 115) and lay persons in the community (N = 300) participated in this research. While both medical student and lay judgments plateaued at high levels of pain severity, judgments regarding cause (medical vs psychological), treatment (opioid prescription), and disability showed growing divergence as levels of reported pain severity increased. Divergence relative to medical and psychological causes of pain was found irrespective of the level of supporting medical evidence; divergence relative to opioid treatment and support for a disability claim was found when supporting medical evidence was low. The results indicate differing expectations of chronic pain treatment for health care providers relative to the lay public that could impact clinical care, especially at high pain severity levels, where lay expectations diverge significantly from those of health professionals. © 2015 American Academy of Pain Medicine.

Productivity, fertilizer responses and nutrient balances of farming systems in central Tigray, Ethiopia: a multi-perspective view in relation to degradation.

NASA Astrophysics Data System (ADS)

Kraaijvanger, Richard; Veldkamp, Tom; Nyssen, Jan

2014-05-01

In many rural livelihoods in sub-Saharan Africa, crop productivity plays an important role since it links with food insecurity, which again is a major constraining factor in livelihood development. Sustainable livelihood development and land degradation are closely connected: lacking sustainability often results in land degradation, whereas the incidence of land degradation frequently frustrates sustainable development. Important forms of land degradation are soil erosion and nutrient depletion, both often being attributed to exhaustive land use practices and both having a direct and major impact on crop productivity. Application of nutrients is an important way to increase productivity. In our study area, central Tigray, development agents recommend the application of fertilizers at high rates in order to boost productivity and to deal with nutrient depletion. In the discussion about the use of fertilizers different perspectives can be taken, in which especially responses and nutrient balances are important issues, linking respectively with socio-economic and agro-ecological livelihood aspects. Ethiopian soils for example are, based on large scale nutrient balances, considered to be depleted, at field scale fertilizer responses are frequently disappointing and achieving sustainable nutrient balances at farm level seems difficult. At a temporal scale however, agricultural systems remained almost unchanged for over 2500 years, suggesting at least some degree of sustainability. With respect to productivity data resulting from on-farm experimentation with natural and artificial fertilizers in 26 sites, we took four perspectives, different in ownership and scale, on nutrient related land degradation and its assumed impact on crop productivity. Taking a farmer perspective we found no significant difference between responses to recommended and current farmer based practices. Taking a more scientific perspective highlighted that, based on the positive correlation between response and soil-P, phosphorus was limiting. A relatively short term farm-level perspective made clear that closing nutrient balances to achieve sustainability is difficult, only the use of manure seemed somewhat satisfactory in this. In case a long term perspective is taken, apparent historical sustainability seems to relate to the combination of relatively low yield levels and mixed farming. Depending on the perspective taken different interventions can be forwarded, all four perspectives however indicate that strengthening the existing mixed farming system provides a promising alternative, allowing the improvement of agro-ecological as well as socio-economic sustainability of involved livelihoods.

Song matching, overlapping, and switching in the banded wren: the sender’s perspective

2008-01-01

Interpreting receiver responses to on-territory playback of aggressive signals is problematic. One solution is to combine such receiver-perspective experiments with a sender-perspective experiment that allows subjects to demonstrate how their choice of singing strategies is associated with their approach behavior. Here we report the results of a sender-perspective study on the banded wren (Thryothorus pleurostictus), and combine information on context and results of previous receiver-perspective experiments to clarify function. Territorial males were presented with a 5-min playback consisting of song types present in their repertoire. We assessed the degree to which the subjects’ song matching rate, overlapping rate, and song-type versatility were correlated with their approach latency, closeness of approach, latency to first retreat, and time spent close to the speaker. Male age, breeding stage, and features of the playback stimuli were also considered. Song matching was associated with rapid and close approach, consistent with the receiver-perspective interpretation of type matching as a conventional signal of aggressive motivation. Overlapping was associated with earlier retreat, and together with the aversive receiver response to our previous overlapping playback experiment suggests that overlapping is a defensive withdrawal signal. High versatility was associated with slower first retreat from the speaker and high levels of reciprocal matching between subject and playback. Males with fledglings sang with particularly low versatility and approached the speaker aggressively, whereas males with nestlings overlapped more and retreated quickly. Finally, older males matched more but overlapped less. PMID:18392112

This study compared nursing staff perceptions of safety climate in clinical units characterized by high and low ratings of leader-member exchange (LMX) and explored characteristics that might account for differences. Frontline nursing leaders' actions are critical to ensure patient safety. Specific leadership behaviors to achieve this goal are underexamined. The LMX perspective has shown promise in nonhealthcare settings as a means to explain safety climate perceptions. Cross-sectional survey of staff (n = 711) and unit directors from 34 inpatient units in an academic medical center was conducted. Significant differences were found between high and low LMX scoring units on supervisor safety expectations, organizational learning-continuous improvement, total communication, feedback and communication about errors, and nonpunitive response to errors. The LMX perspective can be used to identify differences in perceptions of safety climate among nursing staff. Future studies are needed to identify strategies to improve staff safety attitudes and behaviors. Copyright © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins

An organizational approach to understanding patient safety and medical errors.

PubMed

Kaissi, Amer

2006-01-01

Progress in patient safety, or lack thereof, is a cause for great concern. In this article, we argue that the patient safety movement has failed to reach its goals of eradicating or, at least, significantly reducing errors because of an inappropriate focus on provider and patient-level factors with no real attention to the organizational factors that affect patient safety. We describe an organizational approach to patient safety using different organizational theory perspectives and make several propositions to push patient safety research and practice in a direction that is more likely to improve care processes and outcomes. From a Contingency Theory perspective, we suggest that health care organizations, in general, operate under a misfit between contingencies and structures. This misfit is mainly due to lack of flexibility, cost containment, and lack of regulations, thus explaining the high level of errors committed in these organizations. From an organizational culture perspective, we argue that health care organizations must change their assumptions, beliefs, values, and artifacts to change their culture from a culture of blame to a culture of safety and thus reduce medical errors. From an organizational learning perspective, we discuss how reporting, analyzing, and acting on error information can result in reduced errors in health care organizations.

Stakeholders’ perspectives towards effective climate change adaptation on the Mongolian livestock sector

NASA Astrophysics Data System (ADS)

Batbaatar, A.; Apichayakul, P.; Tantanee, S.

2018-03-01

Climate change is one of the greatest threats that world is facing today, and having significant deleterious effects on natural and human systems. Recent climate-induced extreme events and their impacts demand timely adaptation actions to the changing odds of their occurrence. The great phenomenon is already being felt in the Mongolian plateau, especially on the livestock sector. The sector provides the main income and livelihood for one-third of the population of about three million people. A high number of livestock is lost due to a unique phenomenon is known as a “dzud”. This paper examines the key stakeholders’ perspectives in the implementation of climate change adaptation and identifies its barriers, with a focus on the livestock sector. In order to meet the objectives, this research used a semi-structured interview with organizations related to the livestock sector and climate change. The extent of stakeholders’ perspectives might be depending on the way they share information, stakeholder engagement, and their experiences with extreme events, as well as their location and level in government. The research findings will indicate an understanding of climate change perspectives, adaptation, and level of capacity of organizations, which can be used as a guideline for organizations to develop climate change adaptation policies related to the livestock sector in Mongolia.

Religion and suicide acceptability: a cross-national analysis.

PubMed

Stack, Steven; Kposowa, Augustine J

2011-01-01

Four perspectives (moral community thesis, religious integration, religious commitment, and social networks) guide the selection of variables in this study. Data are from the combined World Values/European Values Surveys for 2000 (50,547 individuals nested in 56 nations). The results of a multivariate hierarchical linear model support all four perspectives. Persons residing in nations with relatively high levels of religiosity, who are affiliated with one of four major faiths, are religiously committed, and are engaged with a religious network are found to be lower in suicide acceptability. The religious integration perspective, in particular, is empirically supported; affiliation with Islam is associated with low suicide acceptability. The findings provide strong support for an integrated model and demonstrate the usefulness of the moral community thesis in understanding suicide acceptability.

Adopting a corporate perspective on databases. Improving support for research and decision making.

PubMed

Meistrell, M; Schlehuber, C

1996-03-01

The Veterans Health Administration (VHA) is at the forefront of designing and managing health care information systems that accommodate the needs of clinicians, researchers, and administrators at all levels. Rather than using one single-site, centralized corporate database VHA has constructed several large databases with different configurations to meet the needs of users with different perspectives. The largest VHA database is the Decentralized Hospital Computer Program (DHCP), a multisite, distributed data system that uses decoupled hospital databases. The centralization of DHCP policy has promoted data coherence, whereas the decentralization of DHCP management has permitted system development to be done with maximum relevance to the users'local practices. A more recently developed VHA data system, the Event Driven Reporting system (EDR), uses multiple, highly coupled databases to provide workload data at facility, regional, and national levels. The EDR automatically posts a subset of DHCP data to local and national VHA management. The development of the EDR illustrates how adoption of a corporate perspective can offer significant database improvements at reasonable cost and with modest impact on the legacy system.

The multi-level perspective analysis: Indonesia geothermal energy transition study

NASA Astrophysics Data System (ADS)

Wisaksono, A.; Murphy, J.; Sharp, J. H.; Younger, P. L.

2018-01-01

The study adopts a multi-level perspective in technology transition to analyse how the transition process in the development of geothermal energy in Indonesia is able to compete against the incumbent fossil-fuelled energy sources. Three levels of multi-level perspective are socio-technical landscape (ST-landscape), socio-technical regime (ST-regime) and niche innovations in Indonesia geothermal development. The identification, mapping and analysis of the dynamic relationship between each level are the important pillars of the multi-level perspective framework. The analysis considers the set of rules, actors and controversies that may arise in the technological transition process. The identified geothermal resource risks are the basis of the emerging geothermal technological innovations in Indonesian geothermal. The analysis of this study reveals the transition pathway, which yields a forecast for the Indonesian geothermal technology transition in the form of scenarios and probable impacts.

Hayden, Margaret A; Wolf, Gail A; Zedreck-Gonzalez, Judith F

2016-10-01

The aim of this study was to identify patterns of high-performing behaviors and nurse manager perceptions of the factors of Magnet® sustainability at a multidesignated Magnet organization. The Magnet program recognizes exemplary professional nursing practice and is challenging to achieve and sustain. Only 10% (n = 42) of Magnet hospitals sustained designation for 12 years or longer. This study explored the perspectives of Magnet nurse managers regarding high-performing teams and the sustainability of Magnet designation. A qualitative study of nurse managers was conducted at 1 multidesignated Magnet organization (n = 13). Interview responses were analyzed using pattern recognition of Magnet model domains and characteristics of high-performing teams and then related to factors of Magnet sustainability. Transformational leadership is both an essential factor for sustainability and a potential barrier to sustainability of Magnet designation. Transformational nursing leaders lead high-performing teams and should be in place at all levels as an essential factor in sustaining Magnet redesignation.

Decision making with regard to antiviral intervention during an influenza pandemic.

PubMed

Shim, Eunha; Chapman, Gretchen B; Galvani, Alison P

2010-01-01

Antiviral coverage is defined by the proportion of the population that takes antiviral prophylaxis or treatment. High coverage of an antiviral drug has epidemiological and evolutionary repercussions. Antivirals select for drug resistance within the population, and individuals may experience adverse effects. To determine optimal antiviral coverage in the context of an influenza outbreak, we compared 2 perspectives: 1) the individual level (the Nash perspective), and 2) the population level (utilitarian perspective). We developed an epidemiological game-theoretic model of an influenza pandemic. The data sources were published literature and a national survey. The target population was the US population. The time horizon was 6 months. The perspective was individuals and the population overall. The interventions were antiviral prophylaxis and treatment. The outcome measures were the optimal coverage of antivirals in an influenza pandemic. At current antiviral pricing, the optimal Nash strategy is 0% coverage for prophylaxis and 30% coverage for treatment, whereas the optimal utilitarian strategy is 19% coverage for prophylaxis and 100% coverage for treatment. Subsidizing prophylaxis by $440 and treatment by $85 would bring the Nash and utilitarian strategies into alignment. For both prophylaxis and treatment, the optimal antiviral coverage decreases as pricing of antivirals increases. Our study does not incorporate the possibility of an effective vaccine and lacks probabilistic sensitivity analysis. Our survey also does not completely represent the US population. Because our model assumes a homogeneous population and homogeneous antiviral pricing, it does not incorporate heterogeneity of preference. The optimal antiviral coverage from the population perspective and individual perspectives differs widely for both prophylaxis and treatment strategies. Optimal population and individual strategies for prophylaxis and treatment might be aligned through subsidization.

Experience and perspectives of patient stakeholders regarding patient-centred care and treatment decisions. Our patient stakeholders represented a diverse socio-demographic group. The patient stakeholders identified engagement and dialogue with physicians as crucial elements of patient-centred care model. The degree of patient-centred care was observed to be dependent on the situations. High severity conditions warranted a higher level of patient involvement, compared to mild conditions. They agreed that patient-centred care should not mean that patients can demand inappropriate treatments. An important attribute of patient-centred outcomes research model is the involvement of stakeholders. However, we have limited knowledge about the experience of patient stakeholders in patient-centred outcomes research. Our study indicates that patient stakeholders offer a unique perspective as researchers and policy-makers aim to precisely define patient-centred research and care.

Perceived Ownership of Avatars Influences Visual Perspective Taking

PubMed Central

Böffel, Christian; Müsseler, Jochen

2018-01-01

Modern computer-based applications often require the user to interact with avatars. Depending on the task at hand, spatial dissociation between the orientations of the user and the avatars might arise. As a consequence, the user has to adopt the avatar’s perspective and identify herself/himself with the avatar, possibly changing the user’s self-representation in the process. The present study aims to identify the conditions that benefit this change of perspective with objective performance measures and subjective self-estimations by integrating the idea of avatar-ownership into the cognitive phenomenon of spatial compatibility. Two different instructions were used to manipulate a user’s perceived ownership of an avatar in otherwise identical situations. Users with the high-ownership instruction reported higher levels of perceived ownership of the avatar and showed larger spatial compatibility effects from the avatar’s point of view in comparison to the low ownership instruction. This supports the hypothesis that perceived ownership benefits perspective taking. PMID:29887816

High Power Laser Hybrid Welding - Challenges and Perspectives

NASA Astrophysics Data System (ADS)

Nielsen, Steen Erik

High power industrial lasers at power levels up to 100 kW is now available on the market. Therefore, welding of thicker materials has become of interest for the heavy metal industry e.g. shipyards and wind mill producers. Further, the power plant industry, producers of steel pipes, heavy machinery and steel producers are following this new technology with great interest. At Lindø Welding Technology (LWT), which is a subsidiary to FORCE Technology, a 32-kwatt disc laser is installed. At this laser facility, welding procedures related to thick section steel applications are developed. Material thicknesses between 40 and 100 mm are currently of interest. This paper describes some of the challenges that are related to the development of the high power hybrid laser welding process as well as to the perspectives for the technology as a production tool for the heavy metal industry.

A study was undertaken to develop understanding of hospital chief executive officers' (CEOs') perspectives concerning importance and impact of professional development activities in US hospitals. It was also intended to reveal CEO preferences for various modalities of professional development including membership in professional societies, attainment of credentials, and coaching by mentors. A mail survey of 582 hospital CEOs made use of a pilot-tested questionnaire with 30 close ended multipart questions. Results showed that most CEOs assigned a high level of importance to professional development and favored conferences, seminars, and networking opportunities, but low priority assigned to online activities such as webinars. They reported lending support to senior managers for participation in these activities by providing financial resources and by allowing time off to engage in these activities. The respondents indicated that the importance of various modalities of professional development has either increased or remained high over the recent 5 years. Conclusions suggest that verifiable quantitative data are needed for understanding of the frequency of participation and resource commitment of health care organizations toward the professional development of CEOs and senior managers. The results of this perceptual study reveal a high level of importance accorded to various forms of professional development activities by the participating CEOs.

Anxiety impairs spontaneous perspective calculation: Evidence from a level-1 visual perspective-taking task.

PubMed

Todd, Andrew R; Simpson, Austin J

2016-11-01

Reasoning about other people's mental states is central to social life. Yet, even neuro-typical adults sometimes have perspective-taking difficulties, particularly when another's perspective conflicts with their own. In two experiments, we examined the cognitive mechanisms underlying an affective factor known to hinder perspective taking in adults: anxiety. Using a level-1 visual perspective-taking task, we found that incidentally experiencing anxiety, relative to neutral feelings and anger, impaired the spontaneous calculation of what another social agent can see. Feeling anxious did not, however, impede perspective calculation with a non-social entity, suggesting that anxiety's disruptive effects may be particularly pronounced for social aspects of cognition. These findings help elucidate the mechanisms underlying the effects of incidental emotions on perspective taking and inform debates about "implicit" forms of mentalizing.

2013-01-01

Nurses’ professional capacity plays an important role in the health system to achieve their mission. This study aimed to investigate the perspectives of nursing practitioners about undergraduate nursing internship and apprenticeship courses and possible ways of renewing the courses. This cross sectional survey was performed over 258 bachelors and practitioners of nursing graduates of Alborz University of medical sciences in the second half of 2012. Based on a multi-stage sampling schedule, questionnaires were used to collect data about the perspectives of nursing practitioners about undergraduate nursing internship and apprenticeship courses. There were 81.4% of females and 80.6%, 17.1% and 2.3% of organizational post of participants were nurse, head nurse and supervisor respectively. The occupied posts for 60.1%, 25.6% and 14.1% of subjects, respectively were nurse, head nurse and the supervisor. The application of the internship and apprenticeship courses in bachelor of nursing were in moderate to high levels. The highest percentages of responses for internship and apprenticeship training courses were in internal surgery nursing and special nursing and the minimum percentage of responses were for community hygiene nursing and mental health nursing. Due to observing moderate to high levels of fulfillment and lack of compliance of training courses, renewing to improve the quality and effectiveness of training programs are highly recommended. This can be effective in the future of nursing career and provide a practical training environment to achieve the goals of theoretical training and can lead nurses to become specialized in their field.

2011-01-01

Background Clinical guidelines for management of patients with chronic obstructive pulmonary disease (COPD) include recommendations based on high levels of evidence, but gaps exist in their implementation. The aim of this study was to examine the perspectives of medical practitioners regarding implementation of six high-evidence recommendations for the management of people with COPD. Methods Semi-structured interviews were conducted with medical practitioners involved with care of COPD patients in hospital and general practice. Interviews sought medical practitioners’ experience regarding implementation of smoking cessation, influenza vaccination, pulmonary rehabilitation, guideline-based medications, long-term oxygen therapy for hypoxemia and plan and advice for future exacerbations. Interviews were audiotaped, transcribed verbatim and analyzed using content analysis. Results Nine hospital-based medical practitioners and seven general practitioners participated. Four major categories were identified which impacted on implementation of the target recommendations in the care of patients with COPD: (1) role clarity of the medical practitioner; (2) persuasive communication with the patient; (3) complexity of behavioral change required; (4) awareness and support available at multiple levels. For some recommendations, strength in all four categories provided significant enablers supporting implementation. However, with regard to pulmonary rehabilitation and plans and advice for future exacerbations, all identified categories that presented barriers to implementation. Conclusion This study of medical practitioner perspectives has indicated areas where significant barriers to the implementation of key evidence-based recommendations in COPD management persist. Developing strategies to target the identified categories provides an opportunity to achieve greater implementation of those high-evidence recommendations in the care of people with COPD.

Riparian corridors in arid regions are highly valued for their relative scarcity, and because healthy riparian systems support high levels of biodiversity, can meet human demand for water and water-related resources and functions. Our team is taking a transdiciplinary social-ecological systems approach to assessing riparian corridor resilience in two watersheds (the San Pedro River in USA and Mexico, and the Rio San Miguel in Mexico) through a project funded by the NSF CNH program ("Strengthening Resilience of Arid Region Riparian Corridors"). Multiple perspectives are integrated in the project, including hydrology, ecology, institutional dynamics, and decision making (at the level of both policy and individual choice), as well as the perspectives of various stakeholder groups and individuals in the watersheds. Here we discuss initial findings that center around linking changes in ecohydrology and livelihoods related to decisions in response to climatic, ecological, and social change. The research team is implementing two approaches to integrate the disparate disciplines participating in the research (and the varied perspectives among the stakeholders in this binational riparian context): (1) ecosystem service assessment, and (2) agent based model simulation. We are developing an ecosystem service perspective that provides a bridge between ecological dynamics in the landscape and varied stakeholder perspectives on the implications of ecohydrology for well-being (economic, cultural, ecological). Services are linked on one hand to the spatial patterns of traits of individuals within species (allowing a more predictive application of ecosystem services as they vary with community change in time), and to stakeholder perspectives (facilitating integration of ecosystem services into our understanding of decision making processes) in a case study in the San Pedro River National Conservation Area. The agent- based model (ABM) approach incorporates the influence of human decision-making on spatially-explicit landscapes in a mechanistic way, taking into account social interaction, adaptation, and decision-making at different levels, allowing individual stakeholders to make decisions based on their unique perceptions of their environment, be it economic, social, or ecological awareness. Initial parameterization of the ABM proceeds from a case study centered in the town of Rayón, Sonora, Mexico, where semi-structured interviews were used to elicit perceptions by water resource users of CNH function, change, and solutions relating to livelihood changes in response to several drivers. In both case studies, we see the potential and limitations for an approach to adaptive management and decision support related to water resources that links ecosystem services and agent-based modeling. Methodologically, synthetic approaches such as these may allow coupling of systems for improved assessment and analysis, while at the same time lack a connection to the perspectives of water users and managers on the ground. There is thus potential for a either a loss of system resilience in the face of external change, or an opportunity to increase system resilience by building off perspectives already in place within these coupled socio-ecohydrologic systems.

Perspectives on classical controversies about the motor cortex.

2017-09-01

Primary motor cortex has been studied for more than a century, yet a consensus on its functional contribution to movement control is still out of reach. In particular, there remains controversy as to the level of control produced by motor cortex ("low-level" movement dynamics vs. "high-level" movement kinematics) and the role of sensory feedback. In this review, we present different perspectives on the two following questions: What does activity in motor cortex reflect? and How do planned motor commands interact with incoming sensory feedback during movement? The four authors each present their independent views on how they think the primary motor cortex (M1) controls movement. At the end, we present a dialogue in which the authors synthesize their views and suggest possibilities for moving the field forward. While there is not yet a consensus on the role of M1 or sensory feedback in the control of upper limb movements, such dialogues are essential to take us closer to one.

2017-03-01

High school dropout has been associated with negative outcomes, including increased rates of unemployment, incarceration, and mortality. Dropout rates vary significantly depending on individual and environmental factors. The purpose of our study was to use an ecological perspective to concurrently explore student- and school-level predictors associated with dropout for the purpose of better understanding how to prevent it. We used the Education Longitudinal Study of 2002 dataset. Participants included 14,106 sophomores across 684 public and private schools. We identified variables of interest based on previous research on dropout and implemented hierarchical generalized linear modeling. In the final model, significant student-level predictors included academic achievement, retention, sex, family socioeconomic status (SES), and extracurricular involvement. Significant school-level predictors included school SES and school size. Race/ethnicity, special education status, born in the United States, English as first language, school urbanicity, and school region did not significantly predict dropout after controlling for the aforementioned predictors. Implications for prevention and intervention efforts within a multitiered intervention model are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Today, nurses are required to have knowledge and awareness concerning professional values as standards to provide safe and high-quality ethical care. Nurses' perspective on professional values affects decision-making and patient care. Therefore, the present study aimed to investigate the importance of professional values from clinical nurses' perspective. The present cross-sectional study was conducted in 2016 in four educational hospitals of Kerman University of Medical Sciences, Iran. Data were collected via the Persian version of Nursing Professional Values Scale-Revised (NPVS-R) by Weis and Schank. Sampling was conducted through the use of stratified random sampling method and 250 clinical nurses participated in the study. Results indicated that the total score of the nurses' professional values was high. (102.57 ± 11.94). From nurses' perspective items such as "Maintaining confidentiality of patients" and "Safeguarding patients' right to privacy" had more importance; however, "Recognizing role of professional nursing associations in shaping healthcare policy" and "Participating in nursing research and/or implementing research findings appropriate to practice had less importance. A statistically significant relationship was observed between NPVS-R mean scores and nurses' age, work experience as well as participation in professional ethical training (P < 0.05). Although the total score related to the clinical nurses' perspective on professional values was high, the importance of certain values was at a lower level. Owing to the emerging ethical challenges, it is indispensable to design educational programs in order to improve nurses' awareness and understanding of the comprehensive importance of professional values. Furthermore, it is recommended that mixed methods studies should be conducted in order to design an instrument to evaluate the use of values in nursing practice.

Direct and indirect measures of Level-2 perspective-taking in children and adults.

PubMed

Surtees, Andrew D R; Butterfill, Stephen A; Apperly, Ian A

2012-03-01

Studies with infants show divergence between performance on theory of mind tasks depending on whether direct or indirect measures are used. It has been suggested that direct measures assess a flexible but cognitively demanding ability to reason about the minds of others, whereas indirect measures assess distinct processes which afford more efficient but less flexible theory of mind abilities (Apperly & Butterfill, 2009). This leads to the prediction that performance on indirect measures should be subject to signature limits. The current study tested whether the Level-1/Level-2 distinction might constitute one such limit. The study adapted a task that has shown evidence of Level-1 perspective-taking on both direct and indirect measures (Samson, Apperly, Braithwaite, Andrews, & Bodley-Scott, 2010). The aim was to test Level-2 perspective-taking in a sample of 6- to 11-year-olds (N = 80) and adults (N = 20). Participants were able to make Level-2 judgements on the direct measure. In contrast with the findings from Level-1 perspective-taking, there was no evidence of automatic processing of Level-2 perspectives on the indirect measure. This finding is consistent with the view that theory of mind abilities assessed by indirect measures are subject to signature limits. The Level-1/Level-2 distinction, suitably refined, marks one way in which efficient but inflexible theory of mind abilities are limited. © 2011 The British Psychological Society.

Synergistic Effects of Expectancy and Value on Homework Engagement: The Case for a Within-Person Perspective.

PubMed

Nagengast, Benjamin; Trautwein, Ulrich; Kelava, Augustin; Lüdtke, Oliver

2013-05-01

Historically, expectancy-value models of motivation assumed a synergistic relation between expectancy and value: motivation is high only when both expectancy and value are high. Motivational processes were studied from a within-person perspective, with expectancies and values being assessed or experimentally manipulated across multiple domains and the focus being placed on intraindividual differences. In contrast, contemporary expectancy-value models in educational psychology concentrate almost exclusively on linear effects of expectancy and value on motivational outcomes, with a focus on between-person differences. Recent advances in latent variable methodology allow both issues to be addressed in observational studies. Using the expectancy-value model of homework motivation as a theoretical framework, this study estimated multilevel structural equation models with latent interactions in a sample of 511 secondary school students and found synergistic effects between domain-specific homework expectancy and homework value in predicting homework engagement in 6 subjects. This approach not only brings the "×" back into expectancy-value theory but also reestablishes the within-person perspective as the appropriate level of analysis for latent expectancy-value models.

2013-01-01

The overall aim of this study was to evaluate, from a global and ecological perspective, the relationships between availability of high fructose corn syrup (HFCS) and prevalence of type 2 diabetes. Using published resources, country-level estimates (n =43 countries) were obtained for: total sugar, HFCS and total calorie availability, obesity, two separate prevalence estimates for diabetes, prevalence estimate for impaired glucose tolerance and fasting plasma glucose. Pearson's correlations and partial correlations were conducted in order to explore associations between dietary availability and obesity and diabetes prevalence. Diabetes prevalence was 20% higher in countries with higher availability of HFCS compared to countries with low availability, and these differences were retained or strengthened after adjusting for country-level estimates of body mass index (BMI), population and gross domestic product (adjusted diabetes prevalence=8.0 vs. 6.7%, p=0.03; fasting plasma glucose=5.34 vs. 5.22 mmol/L, p=0.03) despite similarities in obesity and total sugar and calorie availability. These results suggest that countries with higher availability of HFCS have a higher prevalence of type 2 diabetes independent of obesity.

Working with highly pathogenic agents such as Ebola or Marburg virus in the context of infection control or biodefense research requires high-biocontainment laboratories of the Biosafety Level 4 (BSL-4) to protect researchers and laboratory staff from infection and to prevent the unintentional release of harmful agents. The public perception of research on highly pathogenic agents and the operation of high-containment facilities is often ambivalent: while the output of the biomedical research is highly valued, the existence of a BSL-4 lab is often viewed with concern. Biomedical research perspectives and public perceptions often differ and can lead to tensions that could have negative effects on research, society, and politics. Therefore, risk communication plays a crucial role in siting, building, and operating a high-containment facility. The Japanese government invited risk communication experts and scientists from Canada, the U.S., Europe, and Australia to discuss their risk communication strategies for BSL-4 labs. This article describes the international perspective on risk communication and gives recommendations for successful strategies.

Individual- and community-level determinants of Inuit youth mental wellness.

Following the onset of intensive colonial intervention and rapid social change in the lives of Inuit people, youth in Nunavik have experienced high rates of mental health problems and suicide. Inuit people describe a broad range of contextual influences on mental wellness based on lived experience, but most epidemiological studies have focused on individual risk factors and pathologies. This study aimed to assess the influence of multiple determinants of mental wellness among Inuit youth in Nunavik, including culturally meaningful activities, housing and community social characteristics. Mental wellness was measured in the form of two primary outcomes: self-esteem and suicidal ideation. Using cross-sectional data from the 2004 Nunavik Inuit Health Survey and multilevel regression modelling, we estimated associations between these two outcomes and various independent individual- and community-level explanatory factors among Inuit youth. All variables were selected to reflect Inuit perspectives on determinants of mental wellness. The study design and interpretation of results were validated with Inuit community representatives. Pride in Inuit identity, traditional activities, community-level social support and community-level socio-economic status were found to be protective. Barriers to participating in traditional activities, household crowding and high community rates of violence were risk factors. These findings support Inuit perspectives, expand the scope of epidemiological analysis of Inuit mental wellness and reinforce the need for locally informed, community-wide approaches to mental wellness promotion for Inuit youth.

District health manager and mid-level provider perceptions of practice environments in acute obstetric settings in Tanzania: a mixed-method study.

In sub-Saharan Africa, the capacity of human resources for health (HRH) managers to create positive practice environments that enable motivated, productive, and high-performing HRH is weak. We implemented a unique approach to examining HRH management practices by comparing perspectives offered by mid-level providers (MLPs) of emergency obstetric care (EmOC) in Tanzania to those presented by local health authorities, known as council health management teams (CHMTs). This study was guided by the basic strategic human resources management (SHRM) component model. A convergent mixed-method design was utilized to assess qualitative and quantitative data from the Health Systems Strengthening for Equity: The Power and Potential of Mid-Level Providers project. Survey data was obtained from 837 mid-level providers, 83 of whom participated in a critical incident interview whose aim was to elicit negative events in the practice environment that induced intention to leave their job. HRH management practices were assessed quantitatively in 48 districts with 37 members of CHMTs participating in semi-structured interviews. The eight human resources management practices enumerated in the basic SHRM component model were implemented unevenly. On the one hand, members of CHMTs and mid-level providers agreed that there were severe shortages of health workers, deficient salaries, and an overwhelming workload. On the other hand, members of CHMTs and mid-level providers differed in their perspectives on rewards and allocation of opportunities for in-service training. Although written standards of performance and supervision requirements were available in most districts, they did not reflect actual duties. Members of CHMTs reported high levels of autonomy in key HRH management practices, but mid-level providers disputed the degree to which the real situation on the ground was factored into job-related decision-making by CHMTs. The incongruence in perspectives offered by members of CHMTs and mid-level providers points to deficient HRH management practices, which contribute to poor practice environments in acute obstetric settings in Tanzania. Our findings indicate that members of CHMTs require additional support to adequately fulfill their HRH management role. Further research conducted in low-income countries is necessary to determine the appropriate package of interventions required to strengthen the capacity of members of CHMTs.

The vast majority of the extreme sea level events are generated by moderate, rather than extreme skew surges, combined with spring astronomical high tides. We distinguish four broad categories of spatial footprints of events and the distinct storm tracks that generated them. There have been rare events when extreme levels have occurred along two unconnected coastal regions during the same storm. The events that occur in closest succession (<4 days) typically impact different stretches of coastline. The spring/neap tidal cycle prevents successive extreme sea level events from happening within 4–8 days. Finally, the 2013/14 season was highly unusual in the context of the last 100 years from an extreme sea level perspective. PMID:27922630

Objectives: The aim of this systematic review was to evaluate the cost-effectiveness of occupational safety and health interventions from the employer perspective. Methods: A comprehensive literature search (2005 to 2016) in five electronic databases was conducted. Pre-2005 studies were identified from the reference lists of previous studies and systematic reviews, which have similar objective to those of this search. Results: A total of 19 randomized controlled trials and quasi-experimental studies were included, targeting diverse health problems in a number of settings. Few studies included organizational-level interventions. When viewed in relation to the methodological quality and the sufficiency of economic evidence, five of 11 cost-effective occupational safety and health (OSH) interventions appear to be promising. Conclusion: The present systematic review highlights the need for high-quality economic evidence to evaluate the cost-effectiveness of OSH interventions, especially at organizational-level, in all areas of worker health.

Recent changes in the global climate system have resulted in excess mortality and morbidity, particularly among susceptible individuals with preexisting cardiopulmonary disease. These weather patterns are projected to continue and intensify as a result of rising CO2 levels, according to the most recent projections by climate scientists. In this Pulmonary Perspective, motivated by the American Thoracic Society Committees on Environmental Health Policy and International Health, we review the global human health consequences of projected changes in climate for which there is a high level of confidence and scientific evidence of health effects, with a focus on cardiopulmonary health. We discuss how many of the climate-related health effects will disproportionally affect people from economically disadvantaged parts of the world, who contribute relatively little to CO2 emissions. Last, we discuss the financial implications of climate change solutions from a public health perspective and argue for a harmonized approach to clean air and climate change policies.

Mathematics reflecting sensorimotor organization.

McCollum, Gin

2003-02-01

This review combines short presentations of several mathematical approaches that conceptualize issues in sensorimotor neuroscience from different perspectives and levels of analysis. The intricate organization of neural structures and sensorimotor performance calls for characterization using a variety of mathematical approaches. This review points out the prospects for mathematical neuroscience: in addition to computational approaches, there is a wide variety of mathematical approaches that provide insight into the organization of neural systems. By starting from the perspective that provides the greatest clarity, a mathematical approach avoids specificity that is inaccurate in characterizing the inherent biological organization. Approaches presented include the mathematics of ordered structures, motion-phase space, subject-coincident coordinates, equivalence classes, topological biodynamics, rhythm space metric, and conditional dynamics. Issues considered in this paper include unification of levels of analysis, response equivalence, convergence, relationship of physics to motor control, support of rhythms, state transitions, and focussing on low-dimensional subspaces of a high-dimensional sensorimotor space.

Cooperative outcome interdependence, task reflexivity, and team effectiveness: a motivated information processing perspective.

PubMed

De Dreu, Carsten K W

2007-05-01

A motivated information processing perspective (C. K. W. De Dreu & P. J. D. Carnevale, 2003; see also V. B. Hinsz, R. S. Tindale, & D. A. Vollrath, 1997) was used to predict that perceived cooperative outcome interdependence interacts with team-level reflexivity to predict information sharing, learning, and team effectiveness. A cross-sectional field study involving management and cross-functional teams (N = 46) performing nonroutine, complex tasks corroborated predictions: The more team members perceived cooperative outcome interdependence, the better they shared information, the more they learned and the more effective they were, especially when task reflexivity was high. When task reflexivity was low, no significant relationship was found between cooperative outcome interdependence and team processes and performance. The author concludes that the motivated information processing perspective is valid outside the confines of the laboratory and can be extended toward teamwork in organizations. 2007 APA, all rights reserved

This study used the biological market perspective and influential statistical models from the marketing field to investigate males' and females' expectations regarding which combination of characteristics are most relevant in ensuring desirable partnerships for same-sex individuals. Thus, 358 Brazilian undergraduates assessed eight descriptions of same-gender stimulus targets (formulated with different levels of physical attractiveness, social skills, and current or prospective social status) and evaluated the overall desirability of the targets' expected or probable partners. From the possible combinations, three groups emerged: for one group, mainly composed of men, status characteristics were the most important attributes; for the others, mostly composed of women, social skills or physical characteristics were identified as most important in appealing to a desirable partner. This work expands the understanding of variability in male and female romantic expectations, and its implications are discussed from an evolutionary perspective.

The relationship between neurobehavioural problems of severe traumatic brain injury (TBI), family functioning and the psychological well-being of the spouse/caregiver: path model analysis.

Anderson, Malcolm I; Parmenter, Trevor R; Mok, Magdalena

2002-09-01

This study used a modern theory of stress as a framework to strengthen the understanding of the relationship between neurobehavioural problems of TBI, family functioning and psychological distress in spouse/caregivers. The research was an ex post facto design utilising a cross-sectional methodology. Path analysis was used to determine the structural effect of neurobehavioural problems on family functioning and psychological distress. Forty-seven female and 17 male spouse/caregivers of partners with severe TBI were recruited. Spouse/caregivers who reported partners with TBI as having high levels of behavioural and cognitive problems experienced high levels of unhealthy family functioning. High levels of unhealthy family functioning were related to high levels of distress in spouse/caregivers, as family functioning had a moderate influence on psychological distress. Furthermore, indirect effects of behavioural and cognitive problems operating through family functioning intensified the level of psychological distress experienced by spouse/caregivers. Additionally, spouse/caregivers who reported high levels of behavioural, communication and social problems in their partners also experienced high levels of psychological distress. This study was significant because the impact of TBI on the spouse/caregiver from a multidimensional perspective is an important and under-researched area in the brain injury and disability field.

Perspectives to breed for improved baking quality wheat varieties adapted to organic growing conditions.

Northwestern European consumers like their bread to be voluminous and easy to chew. These attributes require a raw material that is rich in protein with, among other characteristics, a suitable ratio between gliadins and glutenins. Achieving this is a challenge for organic growers, because they lack cultivars that can realise high protein concentrations under the relatively low and variable availability of nitrogen during the grain-filling phase common in organic farming. Relatively low protein content in wheat grains thus needs to be compensated by a high proportion of high-quality protein. Organic farming therefore needs cultivars with genes encoding for optimal levels of glutenins and gliadins, a maximum ability for nitrogen uptake, a large storage capacity of nitrogen in the biomass, an adequate balance between vegetative and reproductive growth, a high nitrogen translocation efficiency for the vegetative parts into the grains during grain filling and an efficient conversion of nitrogen into high-quality proteins. In this perspective paper the options to breed and grow such varieties are discussed. Copyright © 2011 Society of Chemical Industry.

Consequence Prioritization Process for Potential High Consequence Events (HCE)

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

Freeman, Sarah G.

2016-10-31

This document describes the process for Consequence Prioritization, the first phase of the Consequence-Driven Cyber-Informed Engineering (CCE) framework. The primary goal of Consequence Prioritization is to identify potential disruptive events that would significantly inhibit an organization’s ability to provide the critical services and functions deemed fundamental to their business mission. These disruptive events, defined as High Consequence Events (HCE), include both events that have occurred or could be realized through an attack of critical infrastructure owner assets. While other efforts have been initiated to identify and mitigate disruptive events at the national security level, such as Presidential Policy Directive 41more » (PPD-41), this process is intended to be used by individual organizations to evaluate events that fall below the threshold for a national security. Described another way, Consequence Prioritization considers threats greater than those addressable by standard cyber-hygiene and includes the consideration of events that go beyond a traditional continuity of operations (COOP) perspective. Finally, Consequence Prioritization is most successful when organizations adopt a multi-disciplinary approach, engaging both cyber security and engineering expertise, as in-depth engineering perspectives are required to recognize and characterize and mitigate HCEs. Figure 1 provides a high-level overview of the prioritization process.« less

Cost-effectiveness of population-level expansion of highly active antiretroviral treatment for HIV in British Columbia, Canada: a modelling study.

2015-09-01

Widespread HIV screening and access to highly active antiretroviral treatment (ART) were cost effective in mathematical models, but population-level implementation has led to questions about cost, value, and feasibility. In 1996, British Columbia, Canada, introduced universal coverage of drug and other health-care costs for people with HIV/AIDS and and began extensive scale-up in access to ART. We aimed to assess the cost-effectiveness of ART scale-up in British Columbia compared with hypothetical scenarios of constrained treatment access. Using comprehensive linked population-level data, we populated a dynamic, compartmental transmission model to simulate the HIV/AIDS epidemic in British Columbia from 1997 to 2010. We estimated HIV incidence, prevalence, mortality, costs (in 2010 CAN$), and quality-adjusted life-years (QALYs) for the study period, which was 1997-2010. We calculated incremental cost-effectiveness ratios from societal and third-party-payer perspectives to compare actual practice (true numbers of individuals accessing ART) to scenarios of constrained expansion (75% and 50% probability of accessing ART). We also investigated structural and parameter uncertainty. Actual practice resulted in 263 averted incident cases compared with 75% of observed access and 676 averted cases compared with 50% of observed access to ART. From a third-party-payer perspective, actual practice resulted in incremental cost-effectiveness ratios of $23 679 per QALY versus 75% access and $24 250 per QALY versus 50% access. From a societal perspective, actual practice was cost saving within the study period. When the model was extended to 2035, current observed access resulted in cumulative savings of $25·1 million compared with the 75% access scenario and $65·5 million compared with the 50% access scenario. ART scale-up in British Columbia has decreased HIV-related morbidity, mortality, and transmission. Resulting incremental cost-effectiveness ratios for actual practice, derived within a limited timeframe, were within established cost-effectiveness thresholds and were cost saving from a societal perspective.

Innovative strategies are needed to reduce malaria mortality in high burden countries like Nigeria. Given that one of the important reasons for this high malaria mortality is delay in receiving effective treatment, improved access to such treatment is critical. Intramuscular artesunate could be used at lower-level facilities given its proven efficacy, ease of use and excellent safety profile. The objective of this study was therefore to explore health workers' perspectives on the possible use of intramuscular artesunate as definitive treatment for severe malaria at lower-level facilities, especially when access to referral facilities is challenging. The study was to provide insight as a formative step into the conduct of future experimental studies to ascertain the feasibility of the use of intramuscular artesunate for definitive treatment of severe malaria in lower level facilities where access to referral care is limited. This qualitative study was done across three southern States in Nigeria (Oyo, Cross River and Enugu). Key informant interviews were conducted over a period of three months between October and December 2014 among 90 purposively selected health workers with different roles in malaria case management from primary care to policy level. A thematic content analysis was used to analyse data. Overall, most of health workers and other key informant groups thought that the use of intramuscular artesunate for definitive treatment of severe malaria at lower-level facilities was possible. They however reported human resource and infrastructure constraints as factors affecting the feasibility of intramuscular artesunate use as definitive treatment for severe malaria in lower-level facilities.. Specifically identified barriers included limited numbers of skilled health workers available to manage potential complications of severe malaria and poorly equipped facilities for supportive treatment. Intramuscular artesunate was considered easy to administer and the proximity of lower-level facilities to communities was deemed important in considering the possibility of its use at lower-level facilities. Health workers also emphasised the important role of operational research to provide additional evidence to guide the implementation of existing policy recommendations and inform future policy revisions. From the perspective of health workers, use of intramuscular artesunate for definitive treatment of severe malaria at lower-level health facilities in Nigeria is possible but dependent on availability of skilled workers, well-equipped lower-level facilities to provide supportive treatment There is need for further operational research to establish feasibility and guide the implementation of such an intervention.

Airway smooth muscle contraction - perspectives on past, present and future.

Mitchell, H W

2009-10-01

Past and contemporary views of airway smooth muscle (ASM) have led to a high level of understanding of the control and intracellular regulation of force or shortening of ASM and of its possible role in airway disease. As well as the multitude of cellular mechanisms that regulate ASM contraction, a number of structural and mechanical factors, which are only present at the airway and lung level, provide overriding control over ASM. With new knowledge about the cellular physiology and biology of ASM, there is increasing need to understand how ASM contraction is regulated and expressed at these airway and system levels.

The Uncanny Valley Does Not Interfere with Level 1 Visual Perspective Taking

PubMed Central

MacDorman, Karl F.; Srinivas, Preethi; Patel, Himalaya

2014-01-01

When a computer-animated human character looks eerily realistic, viewers report a loss of empathy; they have difficulty taking the character’s perspective. To explain this perspective-taking impairment, known as the uncanny valley, a novel theory is proposed: The more human or less eerie a character looks, the more it interferes with level 1 visual perspective taking when the character’s perspective differs from that of the human observer (e.g., because the character competitively activates shared circuits in the observer’s brain). The proposed theory is evaluated in three experiments involving a dot-counting task in which participants either assumed or ignored the perspective of characters varying in their human photorealism and eeriness. Although response times and error rates were lower when the number of dots faced by the observer and character were the same (congruent condition) than when they were different (incongruent condition), no consistent pattern emerged between the human photorealism or eeriness of the characters and participants’ response times and error rates. Thus, the proposed theory is unsupported for level 1 visual perspective taking. As the effects of the uncanny valley on empathy have not previously been investigated systematically, these results provide evidence to eliminate one possible explanation. PMID:25221383

Theory of mind, insecure attachment and paranoia in adolescents with early psychosis and healthy controls.

Impaired Theory of Mind (ToM) is found in adults with schizophrenia and is associated with paranoid symptoms. Insecure attachment is proposed to underlie impaired ToM as well as paranoia. Insight into associations between insecure attachment and impaired ToM skills may help clinicians and patients to understand interpersonal difficulties and use this knowledge to improve recovery. This study used a visual perspective-taking task to investigate whether cognitive ToM is already impaired in adolescents with early psychosis as compared to controls. Also investigated was whether perspective-taking and paranoia are associated with insecure (adult) attachment. Thirty-two adolescent patients with early psychosis and 78 healthy controls participated in this cross-sectional study design and completed the level 1 perspective-taking task, psychopathology assessments (CAPE, PANSS), paranoid thoughts (GPTS), attachment style (PAM) and the WASI vocabulary. Patients did not significantly differ in level-1 perspective-taking behaviour compared to healthy controls. No significant associations were found between perspective-taking, paranoia and attachment. Insecure attachment was significantly related to paranoid thoughts, after controlling for illness-related symptoms. No impairment of level-1 perspective-taking was found in adolescent patients with early psychosis compared to healthy controls. Results indicate that level-1 perspective-taking is not impaired during the early stages of psychotic illness. The association between paranoia and attachment support previous findings and provide further insight into the nature of psychotic symptoms. Understanding the role of attachment in paranoia may help patients and their care workers to gain insight into the reasons for the development or persistence of symptoms. Future research should compare early psychosis samples with more chronic samples to explore whether perspective-taking deteriorates during the course of the illness.

2017-10-03

This study investigated the relations between maternal and paternal rearing practices and adolescents' depressive symptoms, and whether time perspective in adolescence explains these links. The sample included 306 students (158 girls), aged between 10.83 and 14.42 years. Adolescents completed questionnaires assessing their perceptions of maternal and paternal acceptance and psychological control, and of their future time perspective and depressive symptoms. Adolescents who rated their mothers as more accepting and those who rated their fathers as less psychologically controlling also reported lower levels of depressive symptoms and greater future time perspective. Further, adolescents who had greater future time perspective reported lower levels of depressive symptoms. Finally, time perspective partially mediated the relations of maternal and paternal acceptance, and paternal control with depressive symptoms in adolescence. The findings highlight the unique relations of maternal acceptance and paternal psychological control with adolescents' depressive symptoms, and that future time perspective is one mechanism that might explain why parenting strategies are linked with depressive symptoms in adolescence.

2001-07-01

The recoil distance method (RDM) for measuring pico-second nuclear level lifetimes and its use in nuclear structure studies is reviewed and perspectives for the future are presented. High precision measurements in the mass-130 region, studies of multi-phonon states in rare earth nuclei, the investigation of shape coexistence and the recently discovered phenomenon of "magnetic rotation" are reviewed. Prospects for lifetime measurements in exotic regions of nuclei such as the measurement of lifetimes in neutron rich nuclei populated via spontaneous and heavy-ion induced fission are discussed. Other prospects include the use of the RDM technique in conjunction with recoil separators. The relevance of these techniques for experiments with radioactive ion beams will be discussed.

People who use drugs are continuously subjected to harsh stigmatization through a process of relational and social degradation, which limits their possibility for recovery. This quantitative study explores the perspectives of family members or significant others of illicit drug users, regarding general beliefs about illicit drug use and their stigma. Respondents agree that most people do not trust people who use drugs, disregard individuals who have been hospitalized due to drug problems and do not think people who use drugs are as intelligent as the general population. These findings reveal a high level of public stigma regarding illicit drug use.

Satisfaction with ophthalmology residency training from the perspective of recent graduates: a cross-sectional study

2013-01-01

Background Few studies have evaluated satisfaction with medical residency programs from the perspective of residents or recent graduates. Knowledge of current conditions of teaching might help to identify deficiencies and to provide adequate training. So, the aim of this study was to assess the satisfaction with residency training and to identify deficiencies in this training from the perspective of recent graduates in ophthalmology residency. Methods For this purpose, we developed a questionnaire and gaved it to recent graduates in ophthalmology residency in São Paulo, Brazil, from January to December 2010. The questions contained demographic information (age, sex and time of practice in ophthalmology), a Likert scale to evaluate the level of satisfaction with medical residency concerning clinical knowledge, surgical skills and doctor-patient relationship and questions about deficiency in clinical and surgical areas. Results The areas in which recent residency graduates were very or extremely satisfied were: acquisition of clinical knowledge (89.1%), acquisition of surgical skills (93.4%) and the development of doctor-patient relationship (74.9%). Specific areas of clinical knowledge in which they perceived more deficiency were orbit (48.3%) and ophthalmic pathology (47.9%), and in surgical skills were refractive surgery (65.9%) and orbit (59.2%) Conclusions The assessment of the satisfaction with residency training in ophthalmology from the perspective of recent graduates showed high level of satisfaction and identified specific deficiencies in ophthalmic pathology, refractive surgery and orbit.

The increasing prevalence of chronic diseases among the European working age population, as well as the implications for the individual and societal level, underline the need for policy guidelines targeting the effective inclusion of persons with chronic diseases in the workplace. The aim of the present paper was to explore the perspectives of European and National-level stakeholders on existing strategies for work re-integration of persons with chronic diseases, and to provide policy guidelines. A highly-structured interview protocol was distributed to 58 National level stakeholders (policy makers, professionals and employers) from seven European countries. Additionally, 20 European organizations concerned with health-related issues and employment completed an online survey. The findings reveal that employment-related challenges remain largely unaddressed. Both national and European stakeholders considered the existing legislative frameworks inadequate and appraised the co-ordination for the implementation of employment re-integration policies as ineffective. Policies targeting at work re-integration of persons with chronic diseases at European and national level should focus on consistent cooperation among all key stakeholders, awareness raising to staff and management, dissemination of effective strategies, developing research and evaluation standards and establishing monitoring systems on inclusive labour markets.

Executive function is necessary for perspective selection, not Level-1 visual perspective calculation: evidence from a dual-task study of adults.

PubMed

Qureshi, Adam W; Apperly, Ian A; Samson, Dana

2010-11-01

Previous research suggests that perspective-taking and other "theory of mind" processes may be cognitively demanding for adult participants, and may be disrupted by concurrent performance of a secondary task. In the current study, a Level-1 visual perspective task was administered to 32 adults using a dual-task paradigm in which the secondary task tapped executive function. Results suggested that the secondary task did not affect the calculation of perspective, but did affect the selection of the relevant (Self or Other) perspective for a given trial. This is the first direct evidence of a cognitively efficient process for "theory of mind" in adults that operates independently of executive function. The contrast between this and previous findings points to a distinction between simple perspective-taking and the more complex and cognitively demanding abilities more typically examined in studies of "theory of mind". It is suggested that these findings may provide a parsimonious explanation of the success of infants on 'indirect' measures of perspective-taking that do not explicitly require selection of the relevant perspective.

The current understanding of Arctic ecosystems is deeply rooted in the classical view of a bottom-up controlled system with strong physical forcing and seasonality in primary-production regimes. Consequently, the Arctic polar night is commonly disregarded as a time of year when biological activities are reduced to a minimum due to a reduced food supply. Here, based upon a multidisciplinary ecosystem-scale study from the polar night at 79°N, we present an entirely different view. Instead of an ecosystem that has entered a resting state, we document a system with high activity levels and biological interactions across most trophic levels. In some habitats, biological diversity and presence of juvenile stages were elevated in winter months compared to the more productive and sunlit periods. Ultimately, our results suggest a different perspective regarding ecosystem function that will be of importance for future environmental management and decision making, especially at a time when Arctic regions are experiencing accelerated environmental change [1].

Position of women in the Ladiya society: demographic perspectives.

PubMed

Adak, Dipak Kumar; Bharati, Premananda

2011-06-01

Position of women has been assessed in terms of demographic perspectives among an offshoot population of a depressed class, namely the Ladiya of Pathariya Jat village of Sagar district, Madhya Pradesh, India. Fertility as well as infant mortality both is found to be considerably high among the womenfolk. It reveals that the Ladiya mothers opt for frequent child bearing in order to make up the loss due to infant mortality, despite the consequent risk of their health as well as survival. The present study, however, inferred that to improve overall status of the women, effort should be made to improve their level of educational attainment and increase their active participation in economic activities for better employment. This will help the women to have more autonomy in decision making to overcome the high rate of infant mortality and birth rate--as well as natural growth rate of the study population.

Shifting visions: "delegation" policies and the building of a "rights-based" approach to maternal mortality.

PubMed

Freedman, Lynn P

2002-01-01

"Rights-based" approaches fold human rights principles into the ongoing work of health policy making and programming. The example of delegation of anesthesia provision for emergency obstetric care is used to demonstrate how a rights-based approach, applied to this problem in the context of high-mortality countries, requires decision makers to shift from an individual, ethics-based, clinical perspective to a structural, rights-based, public health perspective. This fluid and context-sensitive approach to human rights also applies at the international level, where the direction of overall maternal mortality reduction strategy is set. By contrasting family planning programs and maternal mortality programs, this commentary argues for choosing the human rights approach that speaks most effectively to the power dynamics underlying the particular health problem being addressed. In the case of maternal death in high-mortality countries, this means a strategic focus on the health care system itself.

2017-09-01

Nearly all global health initiatives give per diems to community health workers (CHWs) in poor countries for short-term work on disease-specific programs. We interviewed CHWs, supervisors, and high-level officials (n = 95) in 6 study sites across sub-Saharan Africa and South Asia in early 2012 about the per diems given to them by the Global Polio Eradication Initiative. These per diems for CHWs ranged from $1.50 to $2.40 per day. International officials defended per diems for CHWs with an array of arguments, primarily that they were necessary to defray the expenses that workers incurred during campaigns. But high-level ministry of health officials in many countries were concerned that even small per diems were unsustainable. By contrast, CHWs saw per diems as a wage; the very small size of this wage led many to describe per diems as unjust. Per diem polio work existed in the larger context of limited and mostly exploitative options for female labor. Taking the perspectives of CHWs seriously would shift the international conversation about per diems toward questions of labor rights and justice in global health pay structures.

Toward Proper Authentication Methods in Electronic Medical Record Access Compliant to HIPAA and C.I.A. Triangle.

PubMed

Tipton, Stephen J; Forkey, Sara; Choi, Young B

2016-04-01

This paper examines various methods encompassing the authentication of users in accessing Electronic Medical Records (EMRs). From a methodological perspective, multiple authentication methods have been researched from both a desktop and mobile accessibility perspective. Each method is investigated at a high level, along with comparative analyses, as well as real world examples. The projected outcome of this examination is a better understanding of the sophistication required in protecting the vital privacy constraints of an individual's Protected Health Information (PHI). In understanding the implications of protecting healthcare data in today's technological world, the scope of this paper is to grasp an overview of confidentiality as it pertains to information security. In addressing this topic, a high level overview of the three goals of information security are examined; in particular, the goal of confidentiality is the primary focus. Expanding upon the goal of confidentiality, healthcare accessibility legal aspects are considered, with a focus upon the Health Insurance Portability and Accountability Act of 1996 (HIPAA). With the primary focus of this examination being access to EMRs, the paper will consider two types of accessibility of concern: access from a physician, or group of physicians; and access from an individual patient.

Seeing meaning in action: a bidirectional link between visual perspective and action identification level.

PubMed

Libby, Lisa K; Shaeffer, Eric M; Eibach, Richard P

2009-11-01

Actions do not have inherent meaning but rather can be interpreted in many ways. The interpretation a person adopts has important effects on a range of higher order cognitive processes. One dimension on which interpretations can vary is the extent to which actions are identified abstractly--in relation to broader goals, personal characteristics, or consequences--versus concretely, in terms of component processes. The present research investigated how visual perspective (own 1st-person vs. observer's 3rd-person) in action imagery is related to action identification level. A series of experiments measured and manipulated visual perspective in mental and photographic images to test the connection with action identification level. Results revealed a bidirectional causal relationship linking 3rd-person images and abstract action identifications. These findings highlight the functional role of visual imagery and have implications for understanding how perspective is involved in action perception at the social, cognitive, and neural levels.

Li, Lin; Zhang, Yu; Maytag, Allison L; Jiang, Jack J

2015-07-01

From the perspective of the glottal area and mucosal wave, quantitatively estimate the differences of vocal fold on laryngeal activity during phonation at three different dehydration levels. Controlled three sets of tests. A dehydration experiment for 10 excised canine larynges was conducted at 16 cm H2O. According to the dehydration cycle time (H), dehydration levels were divided into three degrees (0% H, 50% H, 75% H). The glottal area and mucosal wave under three dehydration levels were extracted from high-speed images and digital videokymography (DKG) image sequences. Direct and non-direct amplitude components were derived from glottal areas. The amplitude and frequency of mucosal wave were calculated from DKG image sequences. These parameters in condition of three dehydration levels were compared for statistical analysis. The results showed a significant difference in direct (P = 0.001; P = 0.005) and non-direct (P = 0.005; P = 0.016) components of glottal areas between every two different dehydration levels. Considering the right-upper, right-lower, left-upper, and left-lower of vocal fold, the amplitudes of mucosal waves consistently decreased with increasing of dehydration levels. But, there was no significant difference in frequency. Surface dehydration could give rise to complex variation of vocal fold on tissues and vibratory mechanism, which should need analyzing from multiple perspectives. The results suggested that the combination of glottal area and mucosal wave could be better to research the change of vocal fold at different dehydrations. It would become a better crucial research tool for the clinical treatment of dehydration-induced laryngeal pathologies. Copyright © 2015 The Voice Foundation. Published by Elsevier Inc.

A design perspective on thermal barrier coatings

NASA Astrophysics Data System (ADS)

Soechting, F. O.

1999-12-01

This article addresses the challenges for maximizing the benefit of thermal barrier coatings for turbine engine applications. The perspective is from the viewpoint of a customer, a turbine airfoil designer who is continuously challenged to increase the turbine inlet temperature capability for new products while maintaining cooling flow levels or even reducing them. This is a fundamental requirement for achieving increased engine thrust levels. Developing advanced material systems for the turbine flowpath airfoils, such as high-temperature nickel-base superalloys or thermal barrier coatings to insulate the metal airfoils from the hot flowpath environment, is one approach to solve this challenge. The second approach is to increase the cooling performance of the turbine airfoil, which enables increased flowpath temperatures and reduced cooling flow levels. Thermal barrier coatings have been employed in jet engine applications for almost 30 years. The initial application was on augmentor liners to provide thermal protection during afterburner operation. However, the production use of thermal barrier coatings in the turbine section has only occurred in the past 15 years. The application was limited to stationary parts and only recently incorporated on the rotating turbine blades. This lack of endorsement of thermal barrier coatings resulted from the poor initial duratbility of these coatings in high heat flux environments. Significant improvements have been made to enhance spallation resistance and erosion resistance, which has resulted in increased reliability of these coatings in turbine applications.

Map Changes and Theme Evolution in Work Hours: A Co-Word Analysis

(1) Background: Work hours are the basic carrier impacting employees’ work–life experience and organizational performance, and employees have greater anxiety in relation to work hours as new technology requires an increasingly faster work rhythm. However, scientific research on this topic lags far behind the practice, calling to attention the need for research on work hours from the perspective of historical evolution; (2) Methods: The Bibliometric method is used to analyze the 6364 articles and their contained 77 high-frequency keywords related to work hours from the Web of Science published between 1901 and 2017. Additionally, an individual–organization–society integrative perspective was adopted to describe the map changes and theme evolution of work hours; (3) Results and conclusions: The hot spots of research at the organizational level changed significantly around 1990, with the theme of “long work hours” becoming the core issue in recent years. Studies on the individual level have gradually moved from physiological aspects to the issues of burnout and psychological distress. Research topics related to the social level are somewhat loose, and mainly focused on work–life conflict areas. In addition, the cluster analysis based on the high-frequency keywords classifies six research types according to their research themes. Based on these findings, future trends are proposed to provide theoretical and practical reference for future studies. PMID:29789455

A Comparison of the Social-Adaptive Perspective and Functionalist Perspective on Guilt and Shame

PubMed Central

2017-01-01

Within the field of guilt and shame two competing perspectives have been advanced. The first, the social-adaptive perspective, proposes that guilt is an inherently adaptive emotion and shame is an inherently maladaptive emotion. Thus, those interested in moral character development and psychopathology should work to increase an individual’s guilt-proneness and decrease an individual’s shame-proneness. The functionalist perspective, in contrast, argues that both guilt and shame can serve a person adaptively or maladaptively—depending on the situational appropriateness, duration, intensity, and so forth. This paper reviews the research conducted supporting both positions; critiques some issues with the most widely used guilt- and shame-proneness measure in the social-adaptive research (the TOSCA) and discusses the differences in results found when assessing guilt and shame at the state versus trait level. The conclusion drawn is that although there is broad support for the functionalist perspective across a wide variety of state and trait guilt/shame studies, the functionalist perspective does not yet have the wealth of data supporting it that has been generated by the social-adaptive perspective using the TOSCA. Thus, before a dominant perspective can be identified, researchers need to (1) do more research assessing how the social-adaptive perspective compares to the functionalist perspective at the state level and (2) do more trait research within the functionalist perspective to compare functionalist guilt- and shame-proneness measures with the TOSCA.

Attitudes Toward LGBT Patients Among Students in the Health Professions: Influence of Demographics and Discipline.

PubMed

Wilson, Christina K; West, Lindsey; Stepleman, Lara; Villarosa, Margo; Ange, Brittany; Decker, Matthew; Waller, Jennifer L

2014-09-01

Health providers' personal and professional experiences may predict attitudes toward lesbian, gay, bisexual, and transgender (LGBT) individuals and can therefore serve as key targets for health professions training aimed at decreasing barriers to high-quality patient care. This study explored the relationship between professional, demographic, and training characteristics and health professions student attitudes toward LGBT patients. Students from a health sciences university and applied mental health programs in Georgia (N=475) completed a survey that included a modified version of the Attitudes Toward LGBT Patients Scale (ATLPS). Profession, sexual orientation, current financial status, religion, religiosity, spirituality, and self-reported familiarity with various religious perspectives on sex were associated with ATLPS scores. However, religiosity and self-reported familiarity with various religious perspectives on sex were the only significant predictors of ATLPS scores when these variables were included in one general linear model. Health professions students with higher levels of religiosity and lower levels of self-reported familiarity with various religious perspectives on sex reported less positive attitudes toward LGBT individuals. Results suggest that personal factors may be important to address in interprofessional curriculum related to LGBT patient care. Self-report biases and other factors may limit the accuracy and generalizability of the findings.

Understanding the patient experience of cost-related non-adherence to prescription medications through typology development and application.

2017-12-01

Many patients report skipping doses, splitting pills, or not filling prescriptions due to out-of-pocket costs-a phenomenon known as cost-related non-adherence (CRNA). This study investigated CRNA from the patient's perspective, and, to our knowledge, is the first study to undertake a qualitative investigation of CRNA specifically. We report the results from 35 semi-structured interviews conducted in 2014-15 with adults in four Canadian cities across two provinces. We used framework analysis to develop a CRNA typology to characterize major factors in patients' CRNA decisions. Our typology identifies four major components: (1) the insurance reason driving the drug cost, (2) the individual's overall financial flexibility, (3) the burden of drug cost on the individual's budget, and (4) the importance of the drug from the individual's perspective. The first two components set the context for CRNA and the final two components are the drivers for the CRNA decision. We also found four major patterns in CRNA experiences: (1) CRNA in individuals with low financial flexibility occurred for all levels of drug importance and all but the lowest level of cost burden; (2) CRNA for high importance drugs only occurred when the drug cost had a high burden on an individual's budget; (3) CRNA in individuals with more financial flexibility primarily occurred in drugs with medium importance but high or very high cost burdens; and (4) CRNA for low importance drugs occurred at almost all levels of drug cost burden. Our study furthers the understanding of how numerous factors such as income, insurance, and individual preferences combine and interact to influence CRNA and suggests that policy interventions must be multi-faceted or encourage significant insurance redesign to reduce CRNA.

What Makes Super‐Aged Nations Happier? Exploring Critical Factors of Happiness Among Middle‐Aged Men and Women in Japan

PubMed Central

Tamiya, Nanako; Kawachi, Nobuyuki; Miyairi, Maya

2018-01-01

This study aimed to examine multiple factors associated with happiness from the perspective of gender difference among a middle‐aged Japanese population. A total of 865 participants (male = 344, female = 521) aged 40–64 years were divided into two groups (high and low) by their self‐reported level of happiness. Logistic regression analysis by gender was carried out. In men, high levels of happiness were significantly correlated with living with spouse, occupation, enough sleep, leading a normal life, and regular checkups; while low levels of happiness were significantly correlated with smoking and having two or more diseases. In women, low levels of happiness were significantly correlated with caring for a family member. Our data suggested that the factors relevant to happiness levels might vary between men and women among middle‐aged people in Japan. To increase the nation's level of happiness, the Japanese government must implement extended social services and policymaking, to alleviate caregivers’ burdens, especially among Japanese women.

Perceptions of Intentionality for Goal-Related Action: Behavioral Description Matters

PubMed Central

Monroe, Andrew E.; Reeder, Glenn D.; James, Lauren

2015-01-01

Perceptions of intentionality critically guide everyday social interactions, though the literature provides diverging portraits of how such judgments are made. One view suggests that people have an "intentionality bias," predisposing them toward labeling behaviors as intentional. A second view focuses on a more complex pattern of reasoning whereby judgments of intentionality are shaped by information about social context and mental states. Drawing on the theory of action-identification, we attempt to integrate these two perspectives. We propose that people parse intentionality into two categories: judgments about concrete, low-level behaviors and judgments about relatively more abstract, high-level behaviors. Evidence from five studies supports this distinction. Low-level behaviors were perceived as intentional regardless of mental state information, supporting the “intentionality bias” view. In contrast, judgments about the intentionality of high-level behaviors varied depending on social context and mental states, supporting the systematic view of intentionality. PMID:25781315

Case Managers for High-Risk, High-Cost Patients as Agents and Street-Level Bureaucrats.

PubMed

Swanson, Jeffrey; Weissert, William G

2017-08-01

Case management programs often designate a nurse or social worker to take responsibility for guiding care when patients are expected to be expensive or risk a major decline. We hypothesized that though an intuitively appealing idea, careful program design and faithful implementation are essential if case management programs are to succeed. We employed two theory perspectives, principal-agent framework and street-level bureaucratic theory to describe the relationship between program designers (principals) and case managers (agents/street-level bureaucrats) to review 65 case management studies. Most programs were successful in limited program-specific process and outcome goals. But there was much less success in cost-saving or cost-effectiveness-the original and overarching goal of case management. Cost results might be improved if additional ideas of agency and street-level theory were adopted, specifically, incentives, as well as "green tape," clear rules, guidelines, and algorithms relating to resource allocation among patients.

Renewable Electricity Futures: Exploration of a U.S. Grid with 80% Renewable Electricity

NASA Astrophysics Data System (ADS)

Mai, Trieu

2013-04-01

Renewable Electricity Futures is an initial investigation of the extent to which renewable energy supply can meet the electricity demands of the contiguous United States over the next several decades. This study explores the implications and challenges of very high renewable electricity generation levels: from 30% up to 90% (focusing on 80%) of all U.S. electricity generation from renewable technologies in 2050. At such high levels of renewable electricity penetration, the unique characteristics of some renewable resources, specifically geographical distribution and variability and un-certainty in output, pose challenges to the operability of the nation's electric system. The study focuses on key technical implications of this environment from a national perspective, exploring whether the U.S. power system can supply electricity to meet customer demand on an hourly basis with high levels of renewable electricity, including variable wind and solar generation. The study also identifies some of the potential economic, environmental, and social implications of deploying and integrating high levels of renewable electricity in the U.S. The full report and associated supporting information is available at: http://www.nrel.gov/analysis/refutures/.

Airport community acceptance of High Speed Civil Transport (HSCT) noise levels will depend on the relative noise levels of airplanes flying at the time of introduction. The 85 dBA noise contours for the range of large subsonic airplanes that are expected to be in service in the early 21st century are shown as a shaded area. A certifiable HSCT noise contour as shown, would be somewhat wider along the runway, but about the same in the residential areas downrange. An HSCT noise rule should insure this noise capability.

Hülsheger, Ute R; Lang, Jonas W B; Depenbrock, Franziska; Fehrmann, Carmen; Zijlstra, Fred R H; Alberts, Hugo J E M

2014-11-01

In this research, we examined the role of mindfulness for recovery from work using a daily diary design (N = 121; 5 days; 3 measurement occasions per day). The first goal of the study was to investigate the relationship of mindfulness with sleep quality and the mediating role of psychological detachment from a day-level perspective. A second goal was to extend the process perspective in recovery research beyond the day level and consider systematic change trajectories in recovery variables over the course of the work week and the role of mindfulness in these trajectories. Results regarding day-level relationships confirmed that mindfulness experienced during work was related to subsequent sleep quality, and this relationship was mediated by psychological detachment from work in the evening. Furthermore, an investigation of the role of mindfulness in recovery change trajectories supported the idea that psychological detachment trajectories increase over the work week for individuals low on mindfulness while there was no systematic mean-level change for individuals high on mindfulness. In contrast, sleep quality followed a linear increase from Monday to Friday for all individuals, irrespective of their levels of trait mindfulness. Practical and theoretical implications for the mindfulness and the recovery literature are discussed in conclusion. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Time perspective and socioeconomic status: a link to socioeconomic disparities in health?

PubMed

Guthrie, Lori C; Butler, Stephen C; Ward, Michael M

2009-06-01

Time perspective is a measure of the degree to which one's thinking is motivated by considerations of the future, present, or past. Time perspective has been proposed as a potential mediator of socioeconomic disparities in health because it has been associated with health behaviors and is presumed to vary with socioeconomic status. In this cross-sectional community-based survey of respondents recruited from hair salons and barber shops in a suburb of Washington DC, we examined the association between time perspective and both education level and occupation. We asked participants (N=525) to complete a questionnaire that included three subscales (future, present-fatalistic, and present-hedonistic) of the Zimbardo Time Perspective Inventory. Participants with more formal education and those with professional occupations had higher scores on the future time perspective subscale, and lower scores on the present-fatalistic subscale, than participants with less formal education or a non-professional occupation. Present-fatalistic scores were also higher among participants whose parents had less formal education. Present-hedonistic scores were not associated with either education level or professional occupation. Time perspective scores were not independently associated with the likelihood of obesity, smoking, or exercise. In this community sample, future time perspective was associated with current socioeconomic status, and past-fatalistic time perspective was associated with both current and childhood socioeconomic status.

Interpersonal Subtypes Within Social Anxiety: The Identification of Distinct Social Features.

PubMed

Cooper, Danielle; Anderson, Timothy

2017-10-05

Although social anxiety disorder is defined by anxiety-related symptoms, little research has focused on the interpersonal features of social anxiety. Prior studies (Cain, Pincus, & Grosse Holtforth, 2010; Kachin, Newman, & Pincus, 2001) identified distinct subgroups of socially anxious individuals' interpersonal circumplex problems that were blends of agency and communion, and yet inconsistencies remain. We predicted 2 distinct interpersonal subtypes would exist for individuals with high social anxiety, and that these social anxiety subtypes would differ on empathetic concern, paranoia, received peer victimization, perspective taking, and emotional suppression. From a sample of 175 undergraduate participants, 51 participants with high social anxiety were selected as above a clinical cutoff on the social phobia scale. Cluster analyses identified 2 interpersonal subtypes of socially anxious individuals: low hostility-high submissiveness (Cluster 1) and high hostility-high submissiveness (Cluster 2). Cluster 1 reported higher levels of empathetic concern, lower paranoia, less peer victimization, and lower emotional suppression compared to Cluster 2. There were no differences between subtypes on perspective taking or cognitive reappraisal. Findings are consistent with an interpersonal conceptualization of social anxiety, and provide evidence of distinct social features between these subtypes. Findings have implications for the etiology, classification, and treatment of social anxiety.

Sport, and use of anabolic androgenic steroids among Icelandic high school students: a critical test of three perspectives.

PubMed

Thorlindsson, Thorolfur; Halldorsson, Vidar

2010-12-20

This study investigates the use of anabolic androgenic steroids (AAS) among a national representative sample of high school students in Iceland. We test several hypotheses drawn from three perspectives. The first perspective focuses on the use of AAS as an individual phenomenon motivated by the desire to succeed in sport. The second perspective views the use of AAS as shaped by norms and values embedded in social relationships of formally organized sport. The third perspective suggests that factors outside sport, which have been shown to correlate with the use of other substances, predict the use of AAS. We use logistic regression and predicted probabilities to analyze data from a national representative survey of 11,031 Icelandic high school students. Our results indicated that the use of AAS is not significantly related to participation in formally organized sports. However, it positively relates to fitness and physical training in informal contexts. We found a relatively strong relationship between the use of AAS and the use of illicit substances and a moderate relationship between AAS use and alcohol and tobacco consumption. We also found a significant negative relationship between AAS use and school integration and school achievement, and a significant positive relationship between AAS use and school anomie. The relation between AAS use and family-related variables was weaker. Finally, we found that the relationship between sport participation, physical exercise, and AAS use varies across levels of anomie and integration. Our findings suggest that the use of AAS and especially illegal substances should be considered more as a social and a health problem rather than a sport specific issue. We found that high school students participating in fitness and informal training outside of formally organized sport clubs are the main risk group and should be the target of prevention efforts. However, this should not be done at the expense of general risk factors that affect AAS and other substances used by the general population. Finally, we suggest that prevention efforts should target both groups and individuals.

The objective of this research is to design an alleged teacher learning path or Hypotetical Learning Trajectory (HLT) to anticipate mathematics anxiety of students in learning algebra. HLT loads expected mathematics learning objectives, estimates the level of knowledge and understanding of the students, as well as the selection of mathematical activity in accordance with the learning competencies. This research uses educational design research method. The research steps consist of a preliminary design, experimental and retrospective analysis. Data were gathered from various sources, such as data is written during the research process of test results, documentation, sheet results of students' work, results of interviews, questionnaires, and video recordings. The subjects of the study were 10 junior high school students. Based on the research identified 2 students at the level of high anxiety, 7 people at medium anxiety level and 1 student at low anxiety level. High anxiety levels about 20%, was approximately 70% and approximately 10% lower. These results can be used as an evaluation and reflection for designing materials that can anticipate mathematics anxiety of students learning algebra concepts.

Verhofstadt, Lesley; Devoldre, Inge; Buysse, Ann; Stevens, Michael; Hinnekens, Céline; Ickes, William; Davis, Mark

2016-01-01

The present study examined how support providers’ empathic dispositions (dispositional perspective taking, empathic concern, and personal distress) as well as their situational empathic reactions (interaction-based perspective taking, empathic concern, and personal distress) relate to the provision of spousal support during observed support interactions. Forty-five committed couples provided questionnaire data and participated in two ten-minute social support interactions designed to assess behaviors when partners are offering and soliciting social support. A video-review task was used to assess situational forms of perspective taking (e.g., empathic accuracy), empathic concern and personal distress. Data were analyzed by means of the multi-level Actor-Partner Interdependence Model. Results revealed that providers scoring higher on affective empathy (i.e., dispositional empathic concern), provided lower levels of negative support. In addition, for male partners, scoring higher on cognitive empathy (i.e., situational perspective taking) was related to lower levels of negative support provision. For both partners, higher scores on cognitive empathy (i.e., situational perspective taking) correlated with more instrumental support provision. Male providers scoring higher on affective empathy (i.e., situational personal distress) provided higher levels of instrumental support. Dispositional perspective taking was related to higher scores on emotional support provision for male providers. The current study furthers our insight into the empathy-support link, by revealing differential effects (a) for men and women, (b) of both cognitive and affective empathy, and (c) of dispositional as well as situational empathy, on different types of support provision.

Enhancing social ability by stimulating right temporoparietal junction.

PubMed

Santiesteban, Idalmis; Banissy, Michael J; Catmur, Caroline; Bird, Geoffrey

2012-12-04

The temporoparietal junction (TPJ) is a key node within the "social brain". Several studies suggest that the TPJ controls representations of the self or another individual across a variety of low-level (agency discrimination, visual perspective taking, control of imitation) and high-level (mentalizing, empathy) sociocognitive processes. We explored whether sociocognitive abilities relying on on-line control of self and other representations could be modulated with transcranial direct current stimulation (tDCS) of TPJ. Participants received excitatory (anodal), inhibitory (cathodal), or sham stimulation before completing three sociocognitive tasks. Anodal stimulation improved the on-line control of self-other representations elicited by the imitation and perspective-taking tasks while not affecting attribution of mental states during a self-referential task devoid of such a requirement. Our findings demonstrate the efficacy of tDCS to improve social cognition and highlight the potential for tDCS to be used as a tool to aid self-other processing in clinical populations.

The mainstream is not electable: when vision triumphs over representativeness in leader emergence and effectiveness.

PubMed

Halevy, Nir; Berson, Yair; Galinsky, Adam D

2011-07-01

Theories of visionary leadership propose that groups bestow leadership on exceptional group members. In contrast, social identity perspectives claim that leadership arises, in part, from a person's ability to be seen as representative of the group. Integrating these perspectives, the authors propose that effective leaders often share group members' perspectives concerning the present, yet offer a unique and compelling vision for the group's future. In addition, although intergroup contexts may increase the value of representativeness, the authors predict that vision dominates representativeness in single-group situations characterized by high levels of collective stress (e.g., a natural disaster). Five studies demonstrated that visionary leaders (those who offer novel solutions to their group's predicament) attract more followers, promote group identification and intrinsic motivation, mobilize collective action, and effectively regulate group members' emotions and reactions to crises compared to representative leaders. The authors discuss when, why, and how vision triumphs over representativeness in leader emergence and effectiveness. © 2011 by the Society for Personality and Social Psychology, Inc

Proctor, Enola K; Chambers, David A

2017-09-01

We report outcomes of an NIH-convened meeting on training for dissemination and implementation (D&I) research, focused on accelerating translation of research to healthcare practice. Participants included leaders of current trainings, center directors, and those trained in existing programs. Given the large proportion of D&I research focused on cancer control, mental health, and substance abuse, participants overwhelmingly reflected the experiences and challenges of gaining capacity in behavioral health-related D&I research. The 2-day meeting required participants to draw upon their experiences to help build a field-wide perspective for D&I research training, identify resources needed to support this perspective, and brainstorm gaps in training that needed to be filled. Questions were sent to participants in advance, and responses were synthesized and presented to discuss during the meeting. A preliminary "field-wide" perspective emerged, spanning multiple disciplines, training models, and career levels. Current programs face high demand, need for continued evolution to reflect field advances, and sustainability challenges. Current gaps include implementation practice and predoctoral training. Federal funding is key to D&I research training, be it through grants or agency-led training programs, in order to span and address specialized disease and disorder foci and career tracks.

Time perspective and the theory of planned behavior: moderate predictors of physical activity among central Appalachian adolescents.

Gulley, Tauna; Boggs, Dusta

2014-01-01

The purpose of this study was to determine how well time perspective and the Theory of Planned Behavior (TPB) predicted physical activity among adolescents residing in the central Appalachian region of the United States. A descriptive, correlational design was used. The setting was a rural high school in central Appalachia. The sample included 185 students in grades 9 through 12. Data were collected in school. Variables included components of the TPB, time perspective, and various levels of exercise. Data were analyzed using Pearson's correlation coefficients and multiple regression analysis. The TPB was a moderate predictor of exercise frequency among central Appalachian adolescents, accounting for 42% of the variance. Time perspective did not add to the predictive ability of the TPB to predict exercise frequency in this sample. This study provides support for the TPB for predicting frequency of exercise among central Appalachian adolescents. By understanding the role of the TPB in predicting physical activity among adolescents, nurse practitioners will be able to adapt intervention strategies to improve the physical activity behaviors of this population.

Jinan is a famous spring city in China. Construction of underground metro system may block groundwater seepage, inducing the depletion risk of springs. This paper presents an assessment of the risk due to metro line construction to groundwater in Jinan City using Analytic Hierarchy Process (AHP) and Geographic International System (GIS). Based on the characteristics of hydrogeology and engineering geology, the assessment model is established from the perspectives of surface index and underground index. The assessment results show that the high and very high risk levels of surface index exceed 98% in the north region; and high and very high risk levels of underground index exceed 56% in urban center and southern region. The assessment result also shows that about 14% of the urban area belongs to very high risk level; regions of high risk are 20% in urban area, 9% in Changqing County and 43% in Pingyin County. In the high risk region, metro lines R1 to R3, which are under construction, and metro lines L1 to L5, which are planned, have very high and high risk. Therefore, risk control measures are proposed to protect the groundwater seepage path to spring. PMID:28946709

"A manager in the minds of doctors:" a comparison of new modes of control in European hospitals.

Hospital governance increasingly combines management and professional self-governance. This article maps the new emergent modes of control in a comparative perspective and aims to better understand the relationship between medicine and management as hybrid and context-dependent. Theoretically, we critically review approaches into the managerialism-professionalism relationship; methodologically, we expand cross-country comparison towards the meso-level of organisations; and empirically, the focus is on processes and actors in a range of European hospitals. The research is explorative and was carried out as part of the FP7 COST action IS0903 Medicine and Management, Working Group 2. Comprising seven European countries, the focus is on doctors and public hospitals. We use a comparative case study design that primarily draws on expert information and document analysis as well as other secondary sources. The findings reveal that managerial control is not simply an external force but increasingly integrated in medical professionalism. These processes of change are relevant in all countries but shaped by organisational settings, and therefore create different patterns of control: (1) 'integrated' control with high levels of coordination and coherent patterns for cost and quality controls; (2) 'partly integrated' control with diversity of coordination on hospital and department level and between cost and quality controls; and (3) 'fragmented' control with limited coordination and gaps between quality control more strongly dominated by medicine, and cost control by management. Our comparison highlights how organisations matter and brings the crucial relevance of 'coordination' of medicine and management across the levels (hospital/department) and the substance (cost/quality-safety) of control into perspective. Consequently, coordination may serve as a taxonomy of emergent modes of control, thus bringing new directions for cost-efficient and quality-effective hospital governance into perspective.

The study adopts a multi-level perspective in technology transition to analyse how the transition process in the development of geothermal energy in Indonesia is able to compete against the incumbent fossil-fuelled energy sources. Three levels of multi-level perspective are socio-technical landscape (ST-landscape), socio-technical regime (ST-regime) and niche innovations in Indonesia geothermal development. The identification, mapping and analysis of the dynamic relationship between each level are the important pillars of the multi-level perspective framework. The analysis considers the set of rules, actors and controversies that may arise in the technological transition process. The identified geothermal resource risks are the basis of the emerging geothermal technological innovations in Indonesian geothermal. The analysis of this study reveals the transition pathway, which yields a forecast for the Indonesian geothermal technology transition in the form of scenarios and probable impacts.

2004-10-01

Mixed reality environments represent a new approach to creating technology-mediated experiences. However, there is a lack of empirical research investigating users' actual experience. The aim of the current exploratory, non-experimental study was to establish levels of and identify factors associated with presence, within the framework of Schubert et al.'s model of presence. Using questionnaire and interview methods, the experience of the final performance of the Desert Rain mixed reality environment was investigated. Levels of general and spatial presence were relatively high, but levels of involvement and realness were not. Overall, intrinsic motivation, confidence and intention to re-visit Desert Rain were high. However, age was negatively associated with both spatial presence and confidence to play. Furthermore, various problems in navigating the environment were identified. Results are discussed in terms of Schubert's model and other theoretical perspectives. Implications for system design are presented.

Adjuvant endocrine therapy (AET) utilization is linked to improved clinical outcomes among breast cancer survivors (BCS); yet, AET adherence rates remain suboptimal. Little is known about provider perspectives regarding barriers and facilitators to AET-related symptom management (SM). In this study, we examined provider perspectives on the barriers and facilitators to AET-related SM among BCS and opportunities for improvement. We conducted three focus groups (FGs) with a multidisciplinary group of healthcare providers (n = 13) experienced in caring for BCS undergoing AET. We utilized semi-structured discussion guides to elicit provider perspectives on AET-related SM. FGs were audiotaped, transcribed, and analyzed using qualitative software to identify key themes. Providers described patient-, provider-, and system-level barriers and facilitators to AET-related SM. At the patient-level, barriers included competing demands, limited time/resources, and possible misattribution of some symptoms to AET, while family/social relationships and insurance emerged as important facilitators. Discomfort with SM, limited time, and challenges distinguishing AET-related symptoms from other conditions were key provider-level barriers. Provider-level facilitators included routine symptom documentation and strong provider relationships. Care fragmentation and complexity of the cancer care delivery system were described as system-level barriers; however, survivor clinics were endorsed by providers. Provider perspectives on AET-related SM can shed light on SM barriers and facilitators spanning multiple levels of the cancer care delivery system. Strategies for improving AET-related SM in BCS include increasing patients' knowledge and engagement in SM, equipping providers with efficient SM strategies, and improving coordination of symptom-related services through survivorship programs.

HIV/AIDS Communication Inequalities and Associated Cognitive and Affective Outcomes: A Call for a Socioecological Approach to AIDS Communication in Sub-Saharan Africa.

2017-06-01

Three-and-a-half decades on, no cure or vaccine is yet on the horizon for HIV, making effective behavior change communication (BCC) the key preventive strategy. Despite considerable success, HIV/AIDS BCC efforts have long been criticized for their primary focus on the individual-level field of influence, drawing on the more reductionist view of causation at the individual level. In view of this, we conducted a series of studies that employed a household survey, field experiment, and textual content analysis, and explored the macro-social-level effects of HIV/AIDS-related media and messages on HIV/AIDS cognitive and affective outcomes in Ethiopia. Against a backdrop of epidemiological and socioecological differences, urban versus rural residence has emerged as an important community-level factor that impacts HIV/AIDS-related media and message consumption processes and associated outcomes. The central thread crossing through the six studies included in this paper demonstrates that urban and rural people in high HIV prevalence contexts differ in their concern about and information needs on HIV/AIDS, HIV/AIDS-related media use, and HIV/AIDS-related cognitive and affective outcomes, as well as in their reaction to differently designed/framed HIV prevention messages. This paper proposes that HIV prevention media and message effects in high epidemic situations should be considered from a larger community-level perspective and calls for a socioecological approach to AIDS communication in the hard-hit sub-Saharan Africa. With a number of concrete recommendations to current and future HIV/AIDS BCC efforts in the region, the study joins an emerging body of health communication literature and theorizing that suggests the need to consider media and message effects from a macro-social perspective.

Time perspective and volunteerism: The importance of focusing on the future.

PubMed

Maki, Alexander; Dwyer, Patrick C; Snyder, Mark

2016-01-01

Because volunteerism is a planned activity that unfolds over time, people who more frequently focus on the future might also be more likely to initiate volunteerism and sustain it over time. Using longitudinal (Study 1) and experimental (Study 2) paradigms, we investigated whether time perspective, and in particular a person's orientation toward the future, is related to volunteers' beliefs and behavior. In Study 1, a person's dispositional level of future time perspective was closely linked to volunteer beliefs and behavior. In Study 2, people who wrote about the future reported higher intentions to volunteer, and this was particularly true for infrequent volunteers and those with lower levels of dispositional future time perspective. Across two studies, we found evidence that future time perspective, whether a chronic disposition or a pattern of thought elicited by someone else, is linked to volunteer beliefs and behavior.

Sea level oscillations over minute timescales: a global perspective

Vilibic, Ivica; Sepic, Jadranka

2016-04-01

Sea level oscillations occurring over minutes to a few hours are an important contributor to sea level extremes, and a knowledge on their behaviour is essential for proper quantification of coastal marine hazards. Tsunamis, meteotsunamis, infra-gravity waves and harbour oscillations may even dominate sea level extremes in certain areas and thus pose a great danger for humans and coastal infrastructure. Aside for tsunamis, which are, due to their enormous impact to the coastlines, a well-researched phenomena, the importance of other high-frequency oscillations to the sea level extremes is still underrated, as no systematic long-term measurements have been carried out at a minute timescales. Recently, Intergovernmental Oceanographic Commission (IOC) established Sea Level Monitoring Facility portal (http://www.ioc-sealevelmonitoring.org), making 1-min sea level data publicly available for several hundred tide gauge sites in the World Ocean. Thereafter, a global assessment of oscillations over tsunami timescales become possible; however, the portal contains raw sea level data only, being unchecked for spikes, shifts, drifts and other malfunctions of instruments. We present a quality assessment of these data, estimates of sea level variances and contributions of high-frequency processes to the extremes throughout the World Ocean. This is accompanied with assessment of atmospheric conditions and processes which generate intense high-frequency oscillations.

The increasing prevalence of chronic diseases among the European working age population, as well as the implications for the individual and societal level, underline the need for policy guidelines targeting the effective inclusion of persons with chronic diseases in the workplace. The aim of the present paper was to explore the perspectives of European and National-level stakeholders on existing strategies for work re-integration of persons with chronic diseases, and to provide policy guidelines. A highly-structured interview protocol was distributed to 58 National level stakeholders (policy makers, professionals and employers) from seven European countries. Additionally, 20 European organizations concerned with health-related issues and employment completed an online survey. The findings reveal that employment-related challenges remain largely unaddressed. Both national and European stakeholders considered the existing legislative frameworks inadequate and appraised the co-ordination for the implementation of employment re-integration policies as ineffective.

Remembering as an observer: how is autobiographical memory retrieval vantage perspective linked to depression?

PubMed

Kuyken, Willem; Moulds, Michelle L

2009-08-01

It has long been noted that the emotional impact of an autobiographical memory is associated with the vantage perspective from which it is recalled (Freud, 1950). Memories recalled from a first-person "field" perspective are phenomenologically rich, while third-person "observer" perspective memories contain more descriptive but less affective detail (Nigro & Neisser, 1983). Although there is some evidence that depressed individuals retrieve more observer memories than non-depressed individuals (e.g., Kuyken & Howell, 2006), little is known of the cognitive mechanisms associated with observer memories in depression. At pre- and post-treatment, 123 patients with a history of recurrent depression completed self-report measures and the autobiographical memory task (AMT). Participants also indicated the vantage perspective of the memories recalled on the AMT. Observer memories were less vivid, older, and more frequently rehearsed. The tendency to retrieve observer perspective memories was associated with greater negative self-evaluation, lower dispositional mindfulness, and greater use of avoidance. Furthermore, participants who recalled more field perspective memories at pre-treatment had lower levels of post-treatment depression, controlling for pre-treatment levels of depression and trait rumination. We apply contemporary accounts from social and cognitive psychology, and propose potential mechanisms that link the tendency to retrieve observer perspective memories to depression.

Apron strings of working mothers: Maternal employment and housework in cross-national perspective.

PubMed

Treas, Judith; Tai, Tsui-O

2012-07-01

This paper asks whether maternal employment has a lasting influence on the division of household labor for married women and men. Employing multi-level models with 2002 ISSP survey data for 31 countries, we test the lagged accommodation hypothesis that a long societal history of maternal employment contributes to more egalitarian household arrangements. Our results find that living in a country with a legacy of high maternal employment is positively associated with housework task-sharing, even controlling for the personal socialization experience of growing up with a mother who worked for pay. In formerly socialist countries, however, there is less gender parity in housework than predicted by the high historical level of maternal employment. Copyright © 2012 Elsevier Inc.

Interplay of ICP and IXP over the Internet with power-law features

NASA Astrophysics Data System (ADS)

Fan, Zhongyan; Tang, Wallace Kit-Sang

The Internet is the largest artificial network consisting of billions of IP devices, managed by tens of thousands of autonomous systems (ASes). Due to its importance, the Internet has received much attention and its topological features, mainly in AS-level, have been widely explored from the complex network perspective. However, most of the previous studies assume a homogeneous model in which nodes are indistinguishable in nature. It may be good for a general study of topological structure, but unfortunately it fails to reflect the functionality. The Internet ecology is in fact heterogeneous and highly complex. It consists of various elements such as Internet Exchange Points (IXPs), Internet Content Providers (ICPs), and normal Autonomous System (ASes), realizing different roles in the Internet. In this paper, we propose level-structured network models for investigating how ICP performs under the AS-topology with power-law features and how IXP enhances its performance from a complex network perspective. Based on real data, our results reveal that the power-law nature of the Internet facilitates content delivery not only in efficiency but also in path redundancy. Moreover, the proposed multi-level framework is able to clearly illustrate the significant benefits gained by ICP from IXP peerings.

A Systems-Level Perspective on Engine Ice Accretion

NASA Technical Reports Server (NTRS)

May, Ryan D.; Guo, Ten-Huei; Simon, Donald L.

2013-01-01

The accretion of ice in the compression system of commercial gas turbine engines operating in high ice water content conditions is a safety issue being studied by the aviation sector. While most of the research focuses on the underlying physics of ice accretion and the meteorological conditions in which accretion can occur, a systems-level perspective on the topic lends itself to potential near-term operational improvements. This work focuses on developing an accurate and reliable algorithm for detecting the accretion of ice in the low pressure compressor of a generic 40,000 lbf thrust class engine. The algorithm uses only the two shaft speed sensors and works regardless of engine age, operating condition, and power level. In a 10,000-case Monte Carlo simulation, the detection approach was found to have excellent capability at determining ice accretion from sensor noise with detection occurring when ice blocks an average of 6.8% of the low pressure compressor area. Finally, an initial study highlights a potential mitigation strategy that uses the existing engine actuators to raise the temperature in the low pressure compressor in an effort to reduce the rate at which ice accretes.

Regulatory acceptance and use of 3R models for pharmaceuticals and chemicals: expert opinions on the state of affairs and the way forward.

Pharmaceuticals and chemicals are subjected to regulatory safety testing accounting for approximately 25% of laboratory animal use in Europe. This testing meets various objections and has led to the development of a range of 3R models to Replace, Reduce or Refine the animal models. However, these models must overcome many barriers before being accepted for regulatory risk management purposes. This paper describes the barriers and drivers and options to optimize this acceptance process as identified by two expert panels, one on pharmaceuticals and one on chemicals. To untangle the complex acceptance process, the multilevel perspective on technology transitions is applied. This perspective defines influences at the micro-, meso- and macro level which need alignment to induce regulatory acceptance of a 3R model. This paper displays that there are many similar mechanisms within both sectors that prevent 3R models from becoming accepted for regulatory risk assessment and management. Shared barriers include the uncertainty about the value of the new 3R models (micro level), the lack of harmonization of regulatory requirements and acceptance criteria (meso level) and the high levels of risk aversion (macro level). In optimizing the process commitment, communication, cooperation and coordination are identified as critical drivers. Copyright © 2014 Elsevier Inc. All rights reserved.

Risk management abilities in multimodal maritime supply chains: Visibility and control perspectives.

PubMed

Vilko, Jyri; Ritala, Paavo; Hallikas, Jukka

2016-11-29

Supply chain complexity and disintegration lead to increased uncertainty from a stakeholders' perspective, which is emerging as one of the major challenges of risk management. The ability to identify risks has weakened, as the responsibility of supply chain risk management is handed over to outside service providers. Regardless, the risks, their visibility and their impact depend on the position of the companies in the supply chain. The actors in the chain must therefore collaborate to create effective risk management conditions. This challenging situation is especially pronounced in multimodal maritime supply chains, where the risks and actor focality are high. This paper contributes to current risk management literature by providing a holistic and systemic view of risk visibility and control in maritime supply chains. The study employs broad-based, qualitative interview data collected from actors operating in southern Finland and the Gulf of Finland as well as an expert-panel assessment of the related risk management abilities. The results show a high level of variance in the level of risk identification and visibility between the actors in question. This further suggests that collaboration in supply chain risk management is essential, as an awareness of the risks and their control mechanisms do not necessarily reside in the same company.

From the social-ecological perspective, exposure to violence at the different developmental levels is fundamental to explain the dynamics of violence and victimization in educational centers. The following study aims at analyzing how these relationships are produced in the Peruvian context, where structural violence situations exist. A multi-mediation structural model with 21,416 Peruvian adolescents (M = 13.69; SD = 0.71) was conducted to determine the influence of violence in the school environment on violence perceived within school and violence exercised by teachers. In addition, it was also intended to determine whether these violent relationships predict depression through loneliness, and bullying through peer victimization. The existence of differences between early and late adolescence was also verified. Results confirm that violence in the school setting has high influence on violence exercised by adolescents and teachers within the school. Teacher violence is the most important predictor of depression through loneliness, and encourages peer victimization and the emergence of aggressive behavior. Exposure to violence exercised by support sources-teachers and classmates-explains more than 90% of the total variance explained in bullying behavior. Differences were found between early and late adolescence models. The high prevalence of structural violence in school settings facilitates the bullying/victimization dynamics within school. From a social-ecological perspective, this result suggests the importance of network cooperation at a mesosystem level, with teachers from educational centers playing a crucial role in the prevention of bullying/victimization.

Institutional and relational determinants in high- and medium-extent food product crises: the inner perspective of a public health crisis.

Charlebois, Sylvain; Horan, Hilary

2010-08-01

In 2008, Canada enacted its biggest-ever food recall in response to a Listeria crisis, stemming from a Maple Leaf Foods plant, that killed 22 Canadians. Afterwards, Maple Leaf's market share quickly returned to pre-crisis levels, but the long-term repercussions of the scare still reverberate in Maple Leaf's brand. In this case study, which offers an organizational perspective on the food recall, data was collected, through in-depth interviews of persons involved in the crisis response, and analyzed. The aim of this paper is to make transparent the ways in which Maple Leaf Foods organized their resources to manage the 2008 food recall. Results reveal that institutional and relational determinants are the most important factors in high- and medium-extent food product crises, whereas external and internal effects primarily influence an organization's capacity to cope with severe crises. Based on these findings, a conceptual framework is presented and managerial implications are discussed.

High risk sexual behaviour, alcohol and drug use, and mental health problems combine to yield high levels of HIV-risk behaviour among adolescents with mental health problems. In South Africa, little research has been conducted on parental perspectives of HIV-risk among this population. We conducted a series of focus group discussions with 28 mothers of adolescents receiving services at two mental health clinics in South Africa to identify, from their perspectives, the key community problems facing their children. Participants indicated that HIV remained a serious threat to their adolescent children's well-being, in addition to substance abuse, early sexual debut, and teenage pregnancy. These social problems were mentioned as external to their household dynamics, and thus seemingly beyond the purview of the parent-adolescent relationship. These data have implications for the design of family-based interventions to ameliorate the factors associated with HIV-risk among youth receiving mental health services.

Gold nanoparticles (Au NPs) assembled through Au-S covalent bonds have been widely used in biomolecule-sensing technologies. However, during the process, detection distortions caused by high levels of thiol compounds can still significantly influence the result and this problem has not really been solved. Based on the higher stability of Au-Se bonds compared to Au-S bonds, we prepared selenol-modified Au NPs as an Au-Se nanoplatform (NPF). Compared with the Au-S NPF, the Au-Se NPF exhibits excellent anti-interference properties in the presence of millimolar levels of glutathione (GSH). Such an Au-Se NPF that can effectively avoid detection distortions caused by high levels of thiols thus offers a new perspective in future nanomaterial design, as well as a novel platform with higher stability and selectivity for the in vivo application of chemical sensing and clinical therapies. © 2018 Wiley-VCH Verlag GmbH & Co.

Tsuzuki, Manabu

2015-03-30

This study investigated types of career choice in high school students and examined the effects of career paths on time perspective development. The participants were 4,756 third grade students from nine public high schools in Tokyo. The high school questionnaire survey was conducted throughout autumn of 2008, 2009, and 2010. One year later, 962 graduates participated in the follow-up questionnaire survey by post. Distinguishing gender difference among career paths was found. Girls tend to choose significantly shorter learning careers (p < .01), for example junior college or vocational school in comparison to boys. Career indecision, i.e., students who could not set a concrete future career in high school, had significantly more negative time perspective than other groups (p < .05), which was caused by a deficiency of their basic cognitive ability. Longitudinal data showed different patterns of fluctuation in time perspective between "school to school transition" and "school to work transition". It is suggested that the "school to work transition" tends to be more critical for adolescents and has negative effects on time perspective. These results suggest that the goal content in careers may promote or inhibit the formation of time perspectives during the graduation transition.

Prevention of stroke mortality in Tennessee is a statewide public health priority. These analyses describe how the distribution of Caucasian stroke mortality is greater among the state's Appalachian Counties. For African-American residents, the elevated stroke mortality risk is not distinctive for geographic regions, although Upper East Tennessee rates are elevated. If the Caucasian criteria for assigning "high" rates were used with African-American stroke mortality data, the entire state would be designated as having elevated levels for stroke mortality. Race-gender specific analyses at the county-level (ecological attributes) illustrate the greater risks for "high" county-level stroke mortality rates are present for urban and poor communities in our state. African-American males are a clear exception, where the poorer, rural communities show a protective effect for "high" county-level stroke mortality rates. We support implementing stroke prevention programming and public health interventions based on the mortality data distributions; compatible statewide initiatives are underway We recommend strategic over-sampling of the state's priority populations for stroke risk to facilitate the monitoring of prevention and intervention program impacts over time.

Federal STEM Policy and Politics and Their Impact on Astronomy EPO: Reflections and Provocations

Schultz, G.; Storksdieck, M.; Canright, S.

2015-11-01

The federal government invests more than $3 billion each year across its various units in supporting STEM education and outreach. Efforts in recent years to understand and better coordinate these investments have resulted in considerable pushback, particularly those efforts that aimed at consolidation and elimination of programs deemed ineffective or duplicative. While initial plans to streamline federal STEM education were defeated, many agencies nonetheless saw cuts and elimination, and a high-level effort to coordinate STEM education at the cross-agency level is now gaining steam (CoSTEM: Committee on Science, Technology, Engineering, and Mathematics Education). What do all of these developments mean for education and public outreach in astronomy and related fields? How should this community operate within the opportunities and threats that CoSTEM might pose? Former director of the National Academy of Science's Board on Science Education, and now director of the Center for Research on Lifelong STEM Learning, Martin Storksdieck, reflected on past and recent developments from the perspective of a close observer, and from the perspective of someone who has been involved in astronomy education research and evaluation for nearly 20 years. Shelley Canright, Senior Advisor for Education Integration at the NASA Office of Education, shared her insights and perspectives with respect to CoSTEM and EPO, in particular from co-chairing the Federal Coordination in Science, Technology, Engineering, and Mathematics Education (FC-STEM) group.

Getting ready for petaflop capacities and beyond: a utility perspective

Why should EDF, the leading producer and marketer of electricity in Europe, start adding teraflops to its terawatt-hours and become involved in high-performance computing (HPC)? In this paper we answer this question through examples of major opportunities that HPC brings to our business today and, we hope well into the future of petaflop and exaflop computing. Five cases are presented dealing with nondestructive testing, nuclear fuel management, mechanical behavior of nuclear fuel assemblies, water management, and energy management. For each case we show the benefits brought by HPC, describe the current level of numerical simulation performance, and discuss the perspectives for future steps. We also present the general background that explains why EDF is moving to this technology and briefly comment on the development of user-oriented simulation platforms.

Adaptation of object descriptions to a partner under increasing communicative demands: a comparison of children with and without autism.

PubMed

Nadig, Aparna; Vivanti, Giacomo; Ozonoff, Sally

2009-12-01

This study compared the object descriptions of school-age children with high-functioning autism (HFA) with those of a matched group of typically developing children. Descriptions were elicited in a referential communication task where shared information was manipulated, and in a guessing game where clues had to be provided about the identity of an object that was hidden from the addressee. Across these tasks, increasingly complex levels of audience design were assessed: (1) the ability to give adequate descriptions from one's own perspective, (2) the ability to adjust descriptions to an addressee's perspective when this differs from one's own, and (3) the ability to provide indirect yet identifying descriptions in a situation where explicit labeling is inappropriate. Results showed that there were group differences in all three cases, with the HFA group giving less efficient descriptions with respect to the relevant context than the comparison group. More revealing was the identification of distinct adaptation profiles among the HFA participants: those who had difficulty with all three levels, those who displayed Level 1 audience design but poor Level 2 and Level 3 design, and those demonstrated all three levels of audience design, like the majority of the comparison group. Higher structural language ability, rather than symptom severity or social skills, differentiated those HFA participants with typical adaptation profiles from those who displayed deficient audience design, consistent with previous reports of language use in autism.

Taking an interactional perspective on creativity, the authors examined the influence of social networks and conformity value on employees' creativity. They theorized and found a curvilinear relationship between number of weak ties and creativity such that employees exhibited greater creativity when their number of weak ties was at intermediate levels rather than at lower or higher levels. In addition, employees' conformity value moderated the curvilinear relationship between number of weak ties and creativity such that employees exhibited greater creativity at intermediate levels of number of weak ties when conformity was low than when it was high. A proper match between personal values and network ties is critical for understanding creativity.

Practice Facilitators' and Leaders' Perspectives on a Facilitated Quality Improvement Program.

Practice facilitation is a promising approach to helping practices implement quality improvements. Our purpose was to describe practice facilitators' and practice leaders' perspectives on implementation of a practice facilitator-supported quality improvement program and describe where their perspectives aligned and diverged. We conducted interviews with practice leaders and practice facilitators who participated in a program that included 35 improvement strategies aimed at the ABCS of heart health (aspirin use in high-risk individuals, blood pressure control, cholesterol management, and smoking cessation). Rapid qualitative analysis was used to collect, organize, and analyze the data. We interviewed 17 of the 33 eligible practice leaders, and the 10 practice facilitators assigned to those practices. Practice leaders and practice facilitators both reported value in the program's ability to bring needed, high-quality resources to practices. Practice leaders appreciated being able to set the schedule for facilitation and select among the 35 interventions. According to practice facilitators, however, relying on practice leaders to set the pace of the intervention resulted in a lower level of program intensity than intended. Practice leaders preferred targeted assistance, particularly electronic health record documentation guidance and linkages to state smoking cessation programs. Practice facilitators reported that the easiest interventions were those that did not alter care practices. The dual perspectives of practice leaders and practice facilitators provide a more holistic picture of enablers and barriers to program implementation. There may be greater opportunities to assist small practices through simple, targeted practice facilitator-supported efforts rather than larger, comprehensive quality improvement projects. © 2018 Annals of Family Medicine, Inc.

Guidelines for preparing high school psychology teachers: course-based and standards-based approaches.

2013-01-01

Psychology is one of the most popular elective high school courses. The high school psychology course provides the foundation for students to benefit from psychological perspectives on personal and contemporary issues and learn the rules of evidence and theoretical frameworks of the discipline. The guidelines presented here constitute the second of two reports in this issue of the American Psychologist (January 2013) representing recent American Psychological Association (APA) policies that support high-quality instruction in the teaching of high school psychology. These guidelines, aligned to the standards presented in the preceding report, describe models for the preparation of preservice psychology teachers. The two reports together demonstrate the rigor and competency that should be expected in psychology instruction at the high school level.

A cognitive perspective on Singaporean primary school pupils' use of reading strategies in learning to read in English.

PubMed

Zhang, Lawrence Jun; Gu, Peter Yongqi; Hu, Guangwei

2008-06-01

This study is conducted in Singapore, where learning to read in English is regarded as essential because it is offered as a First Language (L1) subject in the curriculum and is stipulated as the medium of instruction in the education system, and the mother tongues are offered as Second Language (L2) subjects, although the majority still learn English as an L2. The paper reports on the reading strategies used by Singaporean primary school pupils from a cognitive perspective, which is part of a larger study that aims to investigate these pupils' language learning strategies. The participants were 18 pupils from three neighbourhood primary schools, in grades Primary 4, 5 and 6. The data were collected from high- and low-proficiency pupils at each of the three grades in each school, who read two texts at each level. Grounded in an information-processing theory and based on successful experiences of scholars using think-aloud for data collection, we asked the pupils to read and report what they were thinking about while reading. The think-aloud protocols were recorded, transcribed verbatim, coded and analysed. The results suggest that participants' flexible and appropriate use of reading strategies varies according to language proficiency and grade level, with the high-proficiency group outperforming its lower-proficiency counterpart and the high-graders outnumbering the lower-graders in terms of the number of strategies that they used. These differences were also exemplified with qualitative findings from case studies. The use of reading strategies differs according to proficiency levels, and the quality of pupils' strategy-use patterns has more significant implications for understanding efficient reading among primary school pupils.

2013-01-01

This study draws from a life-course perspective in examining trajectories of mothers’ depressive symptoms across their adolescent daughters’ adjustment to parenthood in 204 Mexican-origin families using latent class growth analysis. Four distinct trajectories were identified based on mothers’ depressive symptoms prior to the birth and 10 and 24 months postpartum. Two trajectories were characterized by stable levels of depressive symptoms but were differentiated in their levels of symptoms (i.e., High/Stable and Low/Stable). The remaining two trajectories were characterized by changes from pre- to post-birth, with one group exhibiting increases in depressive symptoms (i.e., Low/Post-Birth Increase) and the other group characterized by decreases in depressive symptoms (i.e., Low/Post-Birth Decrease). Consistent with a risk and resilience perspective, mothers with more disadvantaged socioeconomic circumstances and fewer intrapersonal resources (i.e., self-esteem, ethnic identity affirmation) were more likely to be members of the High/Stable group. In addition, daughters of mothers in the High/Stable group were more likely to have lower self-esteem as compared to daughters in the other three groups. Collectively, these findings suggested that the High/Stable group was at risk for adjustment difficulties from the third trimester to two years postpartum. In contrast, membership in the Low/Post-Birth Decrease trajectory group was associated with lower depressive symptoms and higher self-esteem for mothers and daughters. Findings point to the need to identify mothers who are at risk for depressive symptoms during their adolescent daughters’ pregnancy and offer prevention and intervention programs that reduce risks and enhance protective factors.

Emerging adults' perspectives on their relationships with mothers with mental illness: implications for caregiving.

PubMed

Abraham, Kristen M; Stein, Catherine H

2012-10-01

Guided by a life course perspective, the current study examined whether emerging adults with and without mothers with affective disorders viewed their relationships with their mothers differently, and whether aspects of the emerging adult-mother relationship were associated with reports of caregiving for mothers. Reports from emerging adults with mothers with affective disorders (n = 46) were compared to reports from emerging adults with mothers without mental illness (n = 64). Results indicated that emerging adults with mothers with affective disorders reported significantly lower levels of affection, felt obligation, reciprocity, and future caregiving intentions, and significantly higher levels of role reversal in their relationships with their mothers. Reported current caregiving levels did not differ between emerging adults with and without mothers with affective disorders. Hierarchical multiple regression analyses generally indicated higher levels of felt obligation were associated with higher levels of caregiving, regardless of maternal mental health status. Results and future research directions are discussed from a life course perspective. © 2012 American Orthopsychiatric Association.

Modelling the effects of trade-offs between long and short-term objectives in fisheries management.

PubMed

Mardle, Simon; Pascoe, Sean

2002-05-01

Fisheries management is typically a complex problem, from both an environmental and political perspective. The main source of conflict occurs between the need for stock conservation and the need for fishing community well-being, which is typically measured by employment and income levels. For most fisheries, overexploitation of the stock requires a reduction in the level of fishing activity. While this may lead to long-term benefits (both conservation and economic), it also leads to a short-term reduction in employment and regional incomes. In regions which are heavily dependent on fisheries, short-term consequences of conservation efforts may be considerable. The relatively high degree of scientific uncertainty with respect to the status of the stocks and the relatively short lengths of political terms of office, generally give rise to the short-run view taking the highest priority when defining policy objectives. In this paper, a multi-objective model of the North Sea is developed that incorporates both long-term and short-term objectives. Optimal fleet sizes are estimated taking into consideration different preferences between the defined short-term and long-term objectives. The subsequent results from the model give the short-term and long-term equilibrium status of the fishery incorporating the effects of the short-term objectives. As would be expected, an optimal fleet from a short-term perspective is considerably larger than an optimal fleet from a long-run perspective. Conversely, stock sizes and sustainable yields are considerably lower in the long-term if a short-term perspective is used in setting management policies. The model results highlight what is essentially a principal-agent problem, with the objectives of the policy makers not necessarily reflecting the objectives of society as a whole.

As part of a larger effort to improve teacher capacity for high-quality mathematics instruction, we investigated the factors that are associated with different enactment patterns at three levels: contextual (e.g., type and quality of textbook), individual (e.g., teacher knowledge), and teachers' opportunity-to-learn (e.g., professional development experiences). Analysis of 183 teachers' self-reports on their practices revealed three notable findings. First, the factors at the three levels were all found to be significantly related to the different patterns of enacted curriculum. However, the use of quality textbooks and the alignment of teachers' views and instructional goals with curriculum goals were found to be the two factors that are most strongly associated with the enactment pattern of high-level problems and high-level teacher questions in instruction. Furthermore, teachers with the enactment pattern of increasing lower cognitive demand of problems into higher ones tended to rate their curriculum knowledge higher than teachers with the enactment pattern of using low-level problems and teacher questions in their teaching. In particular, deviation from and dissatisfaction with their assigned low-quality textbooks were found to be critical factors that are associated with the enactment pattern of increasing lower cognitive demands of problems in instruction.

Spatio-structural granularity of biological material entities

PubMed Central

2010-01-01

Background With the continuously increasing demands on knowledge- and data-management that databases have to meet, ontologies and the theories of granularity they use become more and more important. Unfortunately, currently used theories and schemes of granularity unnecessarily limit the performance of ontologies due to two shortcomings: (i) they do not allow the integration of multiple granularity perspectives into one granularity framework; (ii) they are not applicable to cumulative-constitutively organized material entities, which cover most of the biomedical material entities. Results The above mentioned shortcomings are responsible for the major inconsistencies in currently used spatio-structural granularity schemes. By using the Basic Formal Ontology (BFO) as a top-level ontology and Keet's general theory of granularity, a granularity framework is presented that is applicable to cumulative-constitutively organized material entities. It provides a scheme for granulating complex material entities into their constitutive and regional parts by integrating various compositional and spatial granularity perspectives. Within a scale dependent resolution perspective, it even allows distinguishing different types of representations of the same material entity. Within other scale dependent perspectives, which are based on specific types of measurements (e.g. weight, volume, etc.), the possibility of organizing instances of material entities independent of their parthood relations and only according to increasing measures is provided as well. All granularity perspectives are connected to one another through overcrossing granularity levels, together forming an integrated whole that uses the compositional object perspective as an integrating backbone. This granularity framework allows to consistently assign structural granularity values to all different types of material entities. Conclusions The here presented framework provides a spatio-structural granularity framework for all domain reference ontologies that model cumulative-constitutively organized material entities. With its multi-perspectives approach it allows querying an ontology stored in a database at one's own desired different levels of detail: The contents of a database can be organized according to diverse granularity perspectives, which in their turn provide different views on its content (i.e. data, knowledge), each organized into different levels of detail.

Perceptual judgments made better by indirect interactions: Evidence from a joint localization task

PubMed Central

Sebanz, Natalie; Knoblich, Günther

2017-01-01

Others’ perceptual judgments tend to have strong effects on our own, and can improve perceptual judgments when task partners engage in communication. The present study investigated whether individuals benefit from others’ perceptual judgments in indirect interactions, where outcomes of individual decisions can be observed in a shared environment. Participants located a target in a 2D projection of a 3D container either from two complementary viewpoints (Experiment 1), or from a single viewpoint (Experiment 2). Uncertainty about the target location was high on the front-back dimension and low on the left-right dimension. The results showed that pairs of participants benefitted from taking turns in providing judgments. When each member of the pair had access to one complementary perspective, the pair achieved the same level of accuracy as when the two individuals had access to both complimentary perspectives and better performance than when the two individuals had access to only one perspective. These findings demonstrate the important role of a shared environment for successful integration of perceptual information while highlighting limitations in assigning appropriate weights to others’ judgments.

Perspective: Chemical reactions in ionic liquids monitored through the gas (vacuum)/liquid interface.

Maier, F; Niedermaier, I; Steinrück, H-P

2017-05-07

This perspective analyzes the potential of X-ray photoelectron spectroscopy under ultrahigh vacuum (UHV) conditions to follow chemical reactions in ionic liquids in situ. Traditionally, only reactions occurring on solid surfaces were investigated by X-ray photoelectron spectroscopy (XPS) in situ. This was due to the high vapor pressures of common liquids or solvents, which are not compatible with the required UHV conditions. It was only recently realized that the situation is very different when studying reactions in Ionic Liquids (ILs), which have an inherently low vapor pressure, and first studies have been performed within the last years. Compared to classical spectroscopy techniques used to monitor chemical reactions, the advantage of XPS is that through the analysis of their core levels all relevant elements can be quantified and their chemical state can be analyzed under well-defined (ultraclean) conditions. In this perspective, we cover six very different reactions which occur in the IL, with the IL, or at an IL/support interface, demonstrating the outstanding potential of in situ XPS to gain insights into liquid phase reactions in the near-surface region.

Socio-ecological perspective of older age life expectancy: income, gender inequality, and financial crisis in Europe.

PubMed

Kim, Jong In; Kim, Gukbin

2017-08-18

Population is aging rapidly in Europe. Older age life expectancy (OLE) can be influenced by country-level depth of credit information (DCI) as an indicator of financial crisis, gross national income (GNI) per capita, and gender inequality index (GII). These factors are key indicators of socio-ecological inequality. They can be used to develop strategies to reduce country-level health disparity. The objective of this study was to confirm the relationship between socio-ecological factors and OLE in Europe. Data were obtained from World Bank, WHO, and UN database for 34 Europe countries. Associations between socio-ecological factors and OLE were assessed with Pearson correlation coefficients and three regression models. These models assumed that appropriate changes in country-level strategies of healthy aging would produce changes in GNI per capital as personal perspective, GII in social environment perspective, and DCI in public policy perspective to implement socio-ecological changes. Hierarchal linear regression was used for final analysis. Although OLE (women and men) had significant negative correlation with GII (gender inequality index, r = - 0.798, p = 0.001), it had positive correlations with GNI (gross national income per capita, r = 0.834, p = 0.001) and DCI (depth of credit information index, r = 0.704, p = 0.001) levels caused by financial crisis. Higher levels GNI and DCI but lower GII were found to be predictors of OLE (women and men) (R 2  = 0.804, p < 0.001). Factors affecting older age life expectancy in Europe were identified from socio-ecological perspective. Socio-ecological indicators (GII, GNI, and DCI) in Europe appear to have a latent effect on OLE levels. Thus, country-level strategies of successful aging in Europe should target socio-ecological factors such as GII, GNI, and DCI value.

Early problem behavior among children from low-income, mother-headed families: a multiple risk perspective.

PubMed

Olson, Sheryl L; Ceballo, Rosario; Park, Curie

2002-12-01

Examined proximal and contextual factors most strongly related to externalizing behavior among young children growing up in low-income, mother-headed families. Participants were 50 low-income single mothers and their preschool-age children who were visited twice in the home setting. Measures of proximal (low levels of supportive parenting, high levels of punitive disciplinary practices, low levels of maternal emotional well-being) and contextual (low maternal support, high levels of family stress) risk were assessed in relation to maternal reports of child externalizing behavior and an index of negative child behavior during a clean-up task. Child defiance during the clean-up task was highly associated with punitive maternal control in the same situation but had no other direct correlates. However, multiple risk factors representing both proximal and contextual variables were associated with variations in children's behavior problem scores. Mothers of children with high behavior problem scores reported lower feelings of self-efficacy in handling child care and emotional stressors, more frequent use of punitive child disciplinary practices, and lower feelings of satisfaction with the quality of their supportive resources than others. Maternal self-evaluations of coping efficacy mediated the relation between perceived support and child behavior problems, suggesting that constructs of personal control are important to represent in future studies of highly stressed parents.

Parenting Coordination: Applying Clinical Thinking to the Management and Resolution of Post-Divorce Conflict.

PubMed

Demby, Steven L

2016-05-01

There is a small but significant number of parents who remain stuck in a high level of conflict with each other after the legal conclusion of their divorce. Exposure to chronically high levels of parental conflict is a strong risk factor negatively affecting both children's short- and long-term adjustment. Parenting coordination is a nonadversarial, child-focused dispute-resolution process designed to help divorced parents contain their conflict to protect children from its negative effect. Parenting coordination is a hybrid role combining different skills and conflict-resolution approaches. In high-conflict divorce, each parent's internalization of relationship patterns constructed from past experiences contributes to the intractable nature of the interparent conflict. A case presentation illustrates how this clinical perspective enhances the parenting coordinator's ability to work with parents to manage and contain their parenting conflicts with each other. © 2016 Wiley Periodicals, Inc.

Perspective taking and empathic concern in adolescence: gender differences in developmental changes.

2014-03-01

Empathy is an important social skill and is believed to play an essential role in moral development (Hoffman, 2000). In the present longitudinal study, the authors investigated adolescents' development of perspective taking and empathic concern from age 13 to 18 years (mean age at Wave 1 = 13 years, SD = 0.46) and examined its association with pubertal status. Adolescents (283 boys, 214 girls) reported for 6 consecutive years on their dispositional perspective taking and empathic concern and for 4 consecutive years on pubertal status. Latent growth curve modeling revealed gender differences in levels and developmental trends. Gender differences in perspective taking emerged during adolescence, with girls' increases being steeper than those of the boys. Girls also showed higher levels of empathic concern than did boys. Whereas girls' empathic concern remained stable across adolescence, boys showed a decrease from early to middle adolescence with a rebound to the initial level thereafter. Boys who were physically more mature also reported lower empathic concern than did their less physically developed peers. The current study supports theoretical notions that perspective taking develops during adolescence as a result of cognitive development. Moreover, the results suggest that pubertal maturation plays a role in boys' development of empathic concern. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Looking Out From the Top: Differential Effects of Status and Power on Perspective Taking.

PubMed

Blader, Steven L; Shirako, Aiwa; Chen, Ya-Ru

2016-06-01

The impact of hierarchical rank on perspective taking is both practically and theoretically important, prompting considerable research attention to this issue. However, prior research has primarily examined how power affects perspective taking, and has neglected to investigate the impact of status (i.e., the respect and esteem that an individual holds in the eyes of others). Yet status represents a distinct and ubiquitous basis of hierarchical differentiation, one that may profoundly affect perspective taking. The current research addresses this gap, theorizing and testing the prediction that high status enhances perspective taking, in contrast to prior research that has generally found that high power diminishes perspective taking. Five studies, examining various forms of perspective taking across diverse paradigms, provide converging evidence that status and power exert differential effects on perspective taking. Moreover, these studies provide insight regarding the distinction between status and power, as well as the distinct psychology associated with status. © 2016 by the Society for Personality and Social Psychology, Inc.

Readout and retrieval processes are proposed for efficient, high-fidelity quantum state transfer between a matter qubit, encoded in the level structure of a single atom or ion, and a photonic qubit, encoded in a time-reversal-symmetric single-photon wave packet. They are based on controlling spontaneous photon emission and absorption of a matter qubit on demand in free space by stimulated Raman adiabatic passage. As these processes do not involve mode selection by high-finesse cavities or photon transport through optical fibers, they offer interesting perspectives as basic building blocks for free-space quantum-communication protocols.

Molecular-beam epitaxy (MBE) is the “gold standard” synthesis technique for preparing semiconductor heterostructures with high purity, high mobility, and exquisite control of layer thickness at the atomic-layer level. Its use for the growth of multicomponent oxides got off to a rocky start 30 yr ago, but in the ensuing decades, it has become the definitive method for the preparation of oxide heterostructures too, particularly when it is desired to explore their intrinsic properties. Examples illustrating the unparalleled achievements of oxide MBE are given; these motivate its expanding use for exploring the potentially revolutionary states of matter possessed by oxide systems.

Radioisotope Reduction Using Solar Power for Outer Planetary Missions

Fincannon, James

2008-01-01

Radioisotope power systems have historically been (and still are) the power system of choice from a mass and size perspective for outer planetary missions. High demand for and limited availability of radioisotope fuel has made it necessary to investigate alternatives to this option. Low mass, high efficiency solar power systems have the potential for use at low outer planetary temperatures and illumination levels. This paper documents the impacts of using solar power systems instead of radioisotope power for all or part of the power needs of outer planetary spacecraft and illustrates the potential fuel savings of such an approach.

'Vacation for your teeth' - dental tourists in Hungary from the perspective of Hungarian dentists.

PubMed

Kovacs, E; Szocska, G

2013-10-01

Hungary has become a popular destination for foreign patients in the last two decades, particularly in dental care. Since 2008, increasing prices in Western Europe coupled with Hungary's accessibility and availability of dental treatment, has meant the country has become a leader in 'dental tourism'. As the quality of care in Hungary is high and prices are more affordable than in Western Europe, and due to the freedom of movement of people, services and goods within the EU, patient flow into Hungary has increased progressively. The aim of this article is to provide comprehensive empirical evidence from the perspective of a recipient country in dental tourism. A questionnaire survey was conducted among Hungarian dentists (n = 273). Qualitative in-depth interviews were conducted with representatives of dental professional bodies (n = 10). Both research methods aimed to elicit dentists' views on the presence of dental tourism - particularly the push and pull factors (for example, source countries, competitors, information sources, patient motivation). The findings show that there are several reasons why Hungary could maintain a leading position in dental tourism. First, the cost/benefit ratio is outstanding. The affordable price and value for money were already recognised in the early 1990s and were appreciated even before Hungary joined the EU. Secondly, the high quality of Hungary's dental profession: a) dental professionals in Hungary are well-qualified dental practitioners who have received high level dental training; b) dental professional standards are up-to-date and often supervised; c) in Hungary dental technology, the quality of materials and equipment used in dental practices is of European level quality. The rate of complications in dental care is around 5%, similar to other European countries. Finally, previous treatment experiences are positive and patient satisfaction levels are high. More and more patients seek care in Hungary, and more and more patients state that they would be willing to return for further treatment in the future.

Levels and patterns of internal migration in Europe: A cohort perspective.

PubMed

Bernard, Aude

2017-11-01

Europe displays important variations in the level of internal migration, with a clear spatial gradient of high mobility in northern and western Europe but lower mobility in the south and east. However, cross-national variation in levels of internal migration remains poorly understood, because it is analysed almost exclusively using cross-sectional data and period measures. This paper seeks to advance understanding of cross-national variation in migration levels in 14 European countries by drawing on a recently proposed suite of migration cohort measures, coupled with internationally comparable retrospective residential histories. It shows that differences in migration levels are mainly attributable to variation in the extent of repeat movement, which is underpinned by the differences in mean ages at first and last move that together delineate the average length of migration careers. Cohort analysis provides a robust foundation for exploring the demographic mechanisms underpinning variation in migration levels across countries and over time.

Assessing patient's perspective provides useful information enabling a customized approach which has been advocated by current guidelines. In this multicentre cross-sectional study we evaluated personal viewpoints on allergen-specific immunotherapy (SIT) in patients treated with subcutaneous (SCIT) or sublingual (SLIT) immunotherapy. A survey of 28 questions assessing patient's knowledge, perceptions, expectations and satisfaction was developed by an expert panel and was applied by physicians from allergology centres in patients with respiratory allergy treated with SIT. Treating physicians independently reported their satisfaction level regarding SIT for each patient. Fully completed surveys from 434 patients (55.3% male; 66.7% poly-sensitized, 74% SLIT) were analysed. Mean duration of SIT was 2.5 years with different allergens. Most patients acquired their SIT knowledge from their physician (95%) and consequently, their physicians' opinion in their choice to start with SIT was important. Most patients perceived SIT to be safe and easy to integrate into their daily routine. The main motivations for SIT were its supposed potential to alter the course of the disease (45.7%), less need of (28.2%), or dissatisfaction with current pharmacotherapy (19.3%). Both patients' and physicians' satisfaction was high (VAS-scores 74/100 and 78/100, respectively) and showed a significant correlation (SCIT: r=0.612; SLIT: r=0.608). No major difference was found in patients' answers based on the level of education. In this real life study evaluating different aspects of patient's perspective on SIT, the majority of patients had an adequate level of knowledge, perceptions, expectations and satisfaction about SIT, which corresponded well with the physician's perceptions and satisfaction. Our data warrant the use of patient's perspectives on chronic SIT treatment. Copyright © 2012 Elsevier Ltd. All rights reserved.

Limited information is available on patients' perspectives of shared decision-making practices used in inflammatory bowel disease (IBD). The aim of this study was to examine patient insights regarding shared decision making among patients with IBD using novel statistical technology to analyze qualitative data. Two 10-patient focus groups (10 ulcerative colitis patients and 10 Crohn's disease patients) were conducted in Chicago in January 2012 to explore patients' experiences, concerns, and preferences related to shared decision making. Key audio excerpts of focus group insights were embedded within a 25-min online patient survey and used for moment-to-moment affect trace analysis. A total of 355 IBD patients completed the survey (ulcerative colitis 51 %; Crohn's disease 49 %; female 54 %; 18-50 years of age 50 %). The majority of patients (66 %) reported increased satisfaction when they participated in shared decision making. Three unique patient clusters were identified based on their involvement in shared decision making: satisfied, content, and dissatisfied. Satisfied patients (18 %) had a positive physician relationship and a high level of trust with their physician. Content patients (48 %) had a moderate level of trust with their physician. Dissatisfied patients (34 %) had a life greatly affected by IBD, a low level of trust of their physician, a negative relationship with their physician, were skeptical of decisions, and did not rely on their physician for assistance. This study provides valuable insights regarding patients' perceptions of the shared decision-making process in IBD treatment using a novel moment-to-moment hybrid technology approach. Patient perspectives in this study indicate an increased desire for shared decision making in determining an optimal IBD treatment plan.

The aim of this analysis was to compare the level of self-perceived competencies of primary health care physicians in Kosovo with patients' viewpoint, as well as the necessary (required) level of such competencies from decision-makers' standpoint. Three cross-sectional studies were carried out in Kosovo in 2013 including: i) a representative sample of 1340 primary health care users aged ≥18 years (49% men; overall mean age: 50.5±17.9 years; response rate: 89%); ii) a representative sample of 597 primary health care physicians (49% men; overall mean age: 46.0±9.4 years; response rate: 90%), and; iii) a nationwide representative sample of 100 decision-makers operating at different primary health care institutions or public health agencies in Kosovo (63% men; mean age: 47.7±5.7 years). A structured self-administered questionnaire (consisting of 37 items) was used in the three surveys in order to assess physicians' competencies regarding different domains of the quality of health care. There was a significant gap in the level of self-perceived physicians' competencies and patients' perspective in transitional Kosovo. Furthermore, there was a gap in the level of self-perceived physicians' competencies and the necessary (required) level of physicians' competencies from decision-makers perspective which was less evident in Prishtina, but considerable in the other regions of Kosovo. Our analysis provides valuable evidence about the level of competencies of primary health care physicians in Kosovo from different stakeholders' perspectives. There is an urgent need for continuous professional development of family physicians in post-war Kosovo.

Designing across ages: Multi-agent-based models and learning electricity

NASA Astrophysics Data System (ADS)

Sengupta, Pratim

Electricity is regarded as one of the most challenging topics for students at all levels -- middle school -- college (Cohen, Eylon, & Ganiel, 1983; Belcher & Olbert, 2003; Eylon & Ganiel, 1990; Steinberg et al., 1985). Several researchers have suggested that naive misconceptions about electricity stem from a deep incommensurability (Slotta & Chi, 2006; Chi, 2005) or incompatibility (Chi, Slotta & Leauw, 1994; Reiner, Slotta, Chi, & Resnick, 2000) between naive and expert knowledge structures. I first present an alternative theoretical framework that adopts an emergent levels-based perspective as proposed by Wilensky & Resnick (1999). From this perspective, macro-level phenomena such as electric current and resistance, as well as behavior of linear electric circuits, can be conceived of as emergent from simple, body-syntonic interactions between electrons and ions in a circuit. I argue that adopting such a perspective enables us to reconceive commonly noted misconceptions in electricity as behavioral evidences of "slippage between levels" -- i.e., these misconceptions appear when otherwise productive knowledge elements are sometimes inappropriately activated due to certain macro-level phenomenological cues only -- and, that the same knowledge elements when activated due to phenomenological cues at both micro- and macro-levels, can engender a deeper, expert-like understanding. I will then introduce NIELS (NetLogo Investigations In Electromagnetism, Sengupta & Wilensky, 2006, 2008, 2009), a low-threshold high-ceiling (LTHC) learning environment of multi-agent-based computational models that represent phenomena such as electric current and resistance, as well as the behavior of linear electric circuits, as emergent. I also present results from implementations of NIELS in 5th, 7th and 12th grade classrooms that show the following: (a) how leveraging certain "design elements" over others in NIELS models can create new phenomenological cues, which in turn can be appropriated for learners in different grades; (b) how learners' existing knowledge structures can be bootstrapped to generate deep understanding; (c) how these knowledge structures evolve as the learners progress through the implemented curriculum; (d) improvement of learners' understanding in the post-test compared to the pre-test; and (e) how NIELS students compare with a comparison group of 12th grade students who underwent traditional classroom instruction.

Influences of reverse outsourcing on green technological progress from the perspective of a global supply chain.

As a newly appeared trade mode in recent years, reverse outsourcing has made a great impact on traditional trade modes. This paper researched the influences of reverse outsourcing on green technological progress from the perspective of a global supply chain by using micro-data of enterprises. It worked out the rate of green technological progress from two innovative concepts: potential production technology and practical production technology. The empirical analysis results indicated that reverse outsourcing stimulates, and enterprise size and ownership type potentially affects, green technological progress. State-owned or foreign enterprises with high income levels would pay more attention to environmental protection, energy saving, and emission reduction, while small and micro enterprises with low incomes would choose to ignore environmental protection.

Peer delivered, social oriented HIV prevention intervention designs are increasingly popular for addressing broader contexts of health risk beyond a focus on individual factors. Such interventions have the potential to affect multiple social levels of risk and change, including at the individual, network, and community levels, and reflect social ecological principles of interaction across social levels over time. The iterative and feedback dynamic generated by this multi-level effect increases the likelihood for sustained health improvement initiated by those trained to deliver the peer intervention. The Risk Avoidance Partnership (RAP), conducted with heroin and cocaine/crack users in Hartford, Connecticut, exemplified this intervention design and illustrated the multi-level effect on drug users' risk and harm reduction at the individual level, the social network level, and the larger community level. Implications of the RAP program for designing effective prevention programs and for analyzing long-term change to reduce HIV transmission among high-risk groups are discussed from this ecological and multi-level intervention perspective.

Effect of a perspective-taking intervention on the consideration of pain assessment and treatment decisions.

Pain is often poorly managed, highlighting the need to better understand and treat patients' pain. Research suggests that pain is assessed and treated differently depending on patient sex, race, and/or age. Perspective-taking, whereby one envisions the perspective of another, has been found to reduce racial disparities in pain management. This study used virtual human (VH) technology to examine whether a perspective-taking intervention impacts pain management decisions. Ninety-six participants were randomized to an online treatment or control group and viewed 16 video clips of VHs with standardized levels of pain. Participants provided ratings on the VHs' pain intensity and their willingness to administer opioids to them. The intervention group received a brief perspective-taking intervention that consisted of having participants imagine how the patient's suffering could affect his/her life, whereas the control group was asked to wait for the next VH videos to load. A LENS model analysis was used to investigate both group level (nomothetic) and individual level (idiographic) decision policies. A LENS model of analysis is typically used as an analog method for capturing how groups of people and individuals use information in their environment to form judgments. Nomothetic results found that participants rated pain higher and were more likely to prescribe opioids to VHs postintervention, irrespective of group. Idiographic results, however, found that the use of cues to make pain management decisions was mitigated by the perspective-taking group. The participants in the perspective-taking group were more likely to think about pain and the patients' perspective during the intervention, while control participants were more likely to reflect on the VHs' sex, race, or age. A brief intervention may alter participants' pain management decisions. These results indicate that a brief intervention might be an initial step toward aligning observers' pain management ratings with those of the patient. Future research is needed to replicate findings in a health care population.

A Dyadic Perspective on Speech Accommodation and Social Connection: Both Partners' Rejection Sensitivity Matters.

Findings from confederate paradigms predict that mimicry is an adaptive route to social connection for rejection-sensitive individuals (Lakin, Chartrand, & Arkin, 2008). However, dyadic perspectives predict that whether mimicry leads to perceived connection depends on the rejection sensitivity (RS) of both partners in an interaction. We investigated these predictions in 50 college women who completed a dyadic cooperative task in which members were matched or mismatched in being dispositionally high or low in RS. We used a psycholinguistics paradigm to assess, through independent listeners' judgments (N = 162), how much interacting individuals accommodate phonetic aspects of their speech toward each other. Results confirmed predictions from confederate paradigms in matched RS dyads. However, mismatched dyads showed an asymmetry in levels of accommodation and perceived connection: Those high in RS accommodated more than their low-RS partner but emerged feeling less connected. Mediational analyses indicated that low-RS individuals' nonaccommodation in mismatched dyads helped explain their high-RS partners' relatively low perceived connection to them. Establishing whether mimicry is an adaptive route to social connection requires analyzing mimicry as a dyadic process influenced by the needs of each dyad member. © 2014 Wiley Periodicals, Inc.

To inform strategies to address the tuberculosis (TB) excess among US-born African-Americans, we sought to understand the TB experience in the most highly affected southeastern communities. We conducted semi-structured interviews and focus groups in three communities with a TB excess-urban (Georgia and Tennessee) and rural (North Carolina). Participants from five groups provided diverse perspectives-African-Americans: patients with TB disease or latent TB infection (LTBI), or at high risk of contracting TB; and local community leaders and TB program staff. Few differences emerged between sites. Many participants demonstrated low levels of knowledge and awareness and held many misconceptions about TB. Patients expressed a preference for verbal communication of medical information. Patients reported fear of stigmatization and shunning, but few experienced discrimination. Patient trust for TB program staff was high, though community leaders often assumed the opposite. The findings will help guide interventions to improve knowledge and awareness regarding TB, including specific attention to the role of public and private health care providers in dispelling persistent misinformation about TB. The insight from these communities will help build the scientific foundation required to effectively eliminate health inequities.

Chlorella species as hosts for genetic engineering and expression of heterologous proteins: Progress, challenge and perspective.

PubMed

2016-10-01

The species of Chlorella represent a highly specialized group of green microalgae that can produce high levels of protein. Many Chlorella strains can grow rapidly and achieve high cell density under controlled conditions and are thus considered to be promising protein sources. Many advances in the genetic engineering of Chlorella have occurred in recent years, with significant developments in successful expression of heterologous proteins for various applications. Nevertheless, a lot of obstacles remain to be addressed, and a sophisticated and stable Chlorella expression system has yet to emerge. This review provides a brief summary of current knowledge on Chlorella and an overview of recent progress in the genetic engineering of Chlorella, and highlights the advances in the development of a genetic toolbox of Chlorella for heterologous protein expression. Research directions to further exploit the Chlorella expression system with respect to both challenges and perspectives are also discussed. This paper serves as a comprehensive literature review for the Chlorella community and will provide valuable insights into future exploration of Chlorella as a promising host for heterologous protein expression.

Male great bowerbirds create forced perspective illusions with consistently different individual quality

PubMed Central

Kelley, Laura A.; Endler, John A.

2012-01-01

Males often produce elaborate displays that increase their attractiveness to females, and some species extend their displays to include structures or objects that are not part of their body. Such “extended phenotypes” may communicate information that cannot be transmitted by bodily signals or may provide a more reliable signal than bodily signals. However, it is unclear whether these signals are individually distinct and whether they are consistent over long periods of time. Male bowerbirds construct and decorate bowers that function in mate choice. Bower display courts constructed by male great bowerbirds (Ptilonorhynchus nuchalis) induce a visual illusion known as forced perspective for the female viewing the male’s display over the court, and the quality of illusion is associated with mating success. We improved the quality of the forced perspective to determine whether males maintained it at the new higher level, decreased the perspective quality back to its original value, or allowed it to decay at random over time. We found that the original perspective quality was actively recovered to individual original values within 3 d. We measured forced perspective over the course of one breeding season and compared the forced perspective of individual males between two successive breeding seasons. We found that differences in the quality of visual illusion among males were consistent within and between two breeding seasons. This suggests that forced perspective is actively and strongly maintained at a different level by each individual male. PMID:23213203

Client expectations and satisfaction of quality in home care services. A consumer perspective.

Samuelsson, G; Wister, A

2000-12-01

This study examines clients' expectations of quality in home care services and their perceived satisfaction with services among a random sample of 76 home care recipients in Vancouver, Canada. The researchers conducted face-to-face interviews that applied Multiattribute Utility Technology, a procedure that organizes several quality attributes of "ideal" home care into a tree structure to compare their relative importance and ranking from the clients' perspective. Participants also were asked to state their satisfaction or dissatisfaction with the services received in these domains. Among the five main quality attributes identified, the subjects ranked suitability of the home helper and its subset, personal competence, as the most important indicators of quality, followed by continuity in service. In addition, clients tended to have a high level of satisfaction with regard to the attributes of overall home care services. The highest level of satisfaction was reported for elements of personal dispositions of home care staff. The lowest level of satisfaction involved the time/availability components of the service. Finally, comparisons between client expectations and satisfaction of received home care services showed the highest discrepancy for the attributes of influence and time/availability and the greatest congruence for personal attributes of the staff. The results are discussed in terms of their implications for the delivery of home care services.

To be or not to be empathic: the combined role of empathic concern and perspective taking in understanding burnout in general practice

PubMed Central

2014-01-01

Background General practice is stressful and burnout is common among family physicians. A growing body of evidence suggests that the way physicians relate to their patients could be linked to burnout. The goal of this study was to examine how patterns of empathy explained physicians’ burnout. Methods We surveyed 294 French general practitioners (response rate 39%), measured burnout, empathic concern (EC) and perspective taking (PT) using self-reported questionnaires, and modeled burnout levels and frequencies with EC, PT and their interaction in linear and logistic regression analyses. Results Multivariate linear models for burnout prediction were associated with lower PT (β = −0.21, p < 0.001) and lower EC (β = −0.17, p < 0.05). Interestingly, the interaction (EC x PT) also predicted burnout levels (β = 0.11, p < 0.05). The investigation of interactions revealed that high scores on PT predicted lower levels of burnout independent from EC (odd ratios (OR) 0.37; 95% confidence interval (95% CI) 0.21–0.65 p < 0.001), and high scores on both EC and PT were protective against burnout: OR 0.31; 95% CI 0.15–0.63, p < 0.001). Conclusions Deficits in PT alone might be a risk factor for burnout, whereas higher PT and EC might be protective. Educators should take into account how the various components of empathy are potentially associated with emotional outcomes in physicians. PMID:24456299

Background From the social-ecological perspective, exposure to violence at the different developmental levels is fundamental to explain the dynamics of violence and victimization in educational centers. The following study aims at analyzing how these relationships are produced in the Peruvian context, where structural violence situations exist. Methods A multi-mediation structural model with 21,416 Peruvian adolescents (M = 13.69; SD = 0.71) was conducted to determine the influence of violence in the school environment on violence perceived within school and violence exercised by teachers. In addition, it was also intended to determine whether these violent relationships predict depression through loneliness, and bullying through peer victimization. The existence of differences between early and late adolescence was also verified. Results Results confirm that violence in the school setting has high influence on violence exercised by adolescents and teachers within the school. Teacher violence is the most important predictor of depression through loneliness, and encourages peer victimization and the emergence of aggressive behavior. Exposure to violence exercised by support sources—teachers and classmates—explains more than 90% of the total variance explained in bullying behavior. Differences were found between early and late adolescence models. Conclusion The high prevalence of structural violence in school settings facilitates the bullying/victimization dynamics within school. From a social-ecological perspective, this result suggests the importance of network cooperation at a mesosystem level, with teachers from educational centers playing a crucial role in the prevention of bullying/victimization.

This article analyzes the level of progressivity in taxes financing the Brazilian Unified National Health System (SUS). Distribution of the tax burden financing the SUS was calculated using micro-data from the Household Budgets Survey, 2002-2003. The Kakwani index, which shows a tax system's level of progressivity, was calculated. The Kakwani index of public financing was -0.008, and SUS financing was nearly proportional to income. From a social justice perspective this is highly undesirable in a society like Brazil, with a Gini index of 0.57. The system should be clearly progressive in order to counterbalance the country's extreme income concentration.

Gourlan, Mathieu; Trouilloud, David; Boiché, Julie

2016-01-01

Drawing on Self-Determination Theory, this study explored the motivational profiles toward Physical Activity (PA) among adults with type 2 diabetes and the relationships between motivational profile, perceived competence and PA. Participants were 350 men and women (Mean age 62.77 years) who were interviewed on their motivations toward PA, perceived level of competence to practice, and PA practice. Cluster analyses reveal the existence of three distinct profiles: "High Combined" (ie, high scores on motivations ranging from intrinsic to external regulation, moderate level on amotivation), "Self-Determined" (ie, high scores on intrinsic, integrated, and identified regulations; low scores on other regulations), and "Moderate" (ie, moderate scores on all regulations). Participants with "High Combined" and "Self-Determined" profiles reported higher perceived competence and longer leisure-time PA practice in comparison to those with a "Moderate" profile. This study highlights the necessity of adopting a person-centered approach to better understand motivation toward PA among type 2 diabetics.

Using real-world data from the Providence Oregon Telestroke Network, we examined the cost-effectiveness of telestroke from both the spoke and hub perspectives by level of financial responsibility for these costs and by patient stroke severity. We constructed a decision analytic model using patient-level clinical and financial data from before and after telestroke implementation. Effectiveness was measured as quality-adjusted life years (QALYs) and was combined with cost per patient outcomes to calculate incremental cost effectiveness ratios (ICERs). Outcomes were generated (a) overall; (b) by stroke severity, via the National Institute of Health Stroke Scale (NIHSS) at time of arrival, defined as low (<5), medium (5-14) and high (>15); and (c) by percentage of implementation costs paid by spokes (0%, 50%, 100%). Data for 864 patients, 98 pre- and 766 post-implementation, were used to parameterize our model. From the spoke perspective, telestroke had ICERs of US$1322/QALY, US$25,991/QALY and US$50,687/QALY when responsible for 0%, 50%, and 100% of these costs, respectively. Overall, the ICER ranged from US$22,363/QALY to US$71,703/QALY from the hub perspective. Our results support previous models showing good value, overall. However, costs and ICERs varied by stroke severity, with telestroke being most cost-effective for severe strokes. Telestroke was least cost effective for the spokes if spokes paid for more than half of implementation costs. © The Author(s) 2015.

“A manager in the minds of doctors:” a comparison of new modes of control in European hospitals

PubMed Central

2013-01-01

Background Hospital governance increasingly combines management and professional self-governance. This article maps the new emergent modes of control in a comparative perspective and aims to better understand the relationship between medicine and management as hybrid and context-dependent. Theoretically, we critically review approaches into the managerialism-professionalism relationship; methodologically, we expand cross-country comparison towards the meso-level of organisations; and empirically, the focus is on processes and actors in a range of European hospitals. Methods The research is explorative and was carried out as part of the FP7 COST action IS0903 Medicine and Management, Working Group 2. Comprising seven European countries, the focus is on doctors and public hospitals. We use a comparative case study design that primarily draws on expert information and document analysis as well as other secondary sources. Results The findings reveal that managerial control is not simply an external force but increasingly integrated in medical professionalism. These processes of change are relevant in all countries but shaped by organisational settings, and therefore create different patterns of control: (1) ‘integrated’ control with high levels of coordination and coherent patterns for cost and quality controls; (2) ‘partly integrated’ control with diversity of coordination on hospital and department level and between cost and quality controls; and (3) ‘fragmented’ control with limited coordination and gaps between quality control more strongly dominated by medicine, and cost control by management. Conclusions Our comparison highlights how organisations matter and brings the crucial relevance of ‘coordination’ of medicine and management across the levels (hospital/department) and the substance (cost/quality-safety) of control into perspective. Consequently, coordination may serve as a taxonomy of emergent modes of control, thus bringing new directions for cost-efficient and quality-effective hospital governance into perspective.

2013-10-01

This study investigated the relationship between autonomous motivation and academic adjustment based on the perspective of self-determination theory. It also examined motivational profiles to reveal individual differences and the characteristic of these profiles for groups with varying levels of autonomous and controlled regulation (autonomous, controlled, high motivation, and low motivation). Data were collected from 442 junior high school students for academic motivation, academic performance, academic competence, meta-cognitive strategy, academic anxiety, apathy, and stress experience. Correlation analyses generally supported the basic hypothesis of self-determination theory that a more autonomous regulation style was strongly related to academic adjustment. The results also showed that persons with a high autonomous regulation and a low controlled regulation style were the most adaptive.

Mental traveling along psychological distances: The effects of cultural syndromes, perspective flexibility, and construal level.

PubMed

Wong, Vincent Chi; Wyer, Robert S

2016-07-01

Individuals' psychological distance from the stimuli they encounter in daily life can influence the abstractness or generality of the mental representations they form of these stimuli. However, these representations can also depend on the perspective from which the stimuli are construed. When individuals have either an individualistic social orientation or a short-term temporal orientation, they construe psychologically distal events more globally than they construe proximal ones, as implied by construal level theory (Trope & Liberman, 2010). When they have either a collectivistic social orientation or a long-term temporal orientation, however, they not only construe the implications of distal events more concretely than individuals with an egocentric perspective but also construe the implications of proximal events in more abstract terms. These effects are mediated by the flexibility of the perspectives that people take when they make judgments. Differences in perspective flexibility account for the impact of both situationally induced differences in social and temporal orientation and more chronic cultural differences in these orientations.

Background: Vaccine injections are the most common painful needle procedure experienced throughout the lifespan. Many strategies are available to mitigate this pain; however, they are uncommonly utilized, leading to unnecessary pain and suffering. Some individuals develop a high level of fear and subsequent needle procedures are associated with significant distress. Objective: The present work is part of an update and expansion of a 2009 knowledge synthesis to include the management of vaccine-related pain across the lifespan and the treatment of individuals with high levels of needle fear. This article will provide a conceptual foundation for understanding: (a) painful procedures and their role in the development and maintenance of high levels of fear; (b) treatment strategies for preventing or reducing the experience of pain and the development of fear; and (c) interventions for mitigating high levels of fear once they are established. Results: First, the general definitions, lifespan development and functionality, needle procedure-related considerations, and assessment of the following constructs are provided: pain, fear, anxiety, phobia, distress, and vasovagal syncope. Second, the importance of unmitigated pain from needle procedures is highlighted from a developmental perspective. Third, the prevalence, course, etiology, and consequences of high levels of needle fear are described. Finally, the management of needle-related pain and fear are outlined to provide an introduction to the series of systematic reviews in this issue. Discussion: Through the body of work in this supplement, the authors aim to provide guidance in how to treat vaccination-related pain and its sequelae, including high levels of needle fear.

Perspective-taking ability is an essential spatial faculty that is of much interest in both health and neuropsychiatric disorders. There is limited data on the neural correlates of perspective taking in the context of a realistic three-dimensional environment. We report the results of a pilot study exploring the same in eight healthy volunteers. Subjects underwent two runs of an experiment in a 3 Tesla magnetic resonance imaging (MRI) involving alternate blocks of a first-person perspective based allocentric object location memory task (OLMT), a third-person perspective based egocentric visual perspective taking task (VPRT), and a table task (TT) that served as a control. Difference in blood oxygen level dependant response during task performance was analyzed using Statistical Parametric Mapping software, version 12. Activations were considered significant if they survived family-wise error correction at the cluster level using a height threshold of p ＜0.001, uncorrected at the voxel level. A significant difference in accuracy and reaction time based on task type was found. Subjects had significantly lower accuracy in VPRT compared to TT. Accuracy in the two active tasks was not significantly different. Subjects took significantly longer in the VPRT in comparison to TT. Reaction time in the two active tasks was not significantly different. Functional MRI revealed significantly higher activation in the bilateral visual cortex and left temporoparietal junction (TPJ) in VPRT compared to OLMT. The results underscore the importance of TPJ in egocentric manipulation in healthy controls in the context of reality-based spatial tasks.

To systematically assess the service satisfaction of consumers, their families and referrers with crisis resolution (CR). Consecutive consumers discharged after receiving CR over a five-week period were potentially eligible for participation, together with their family and referrer (broadly defined). Structured telephone interviews were conducted and involved forced-choice questions assessing global satisfaction and satisfaction with specific aspects of care, plus two open-ended questions. Participants were 75 consumers, 22 family and 16 referrers. High levels of satisfaction were seen for all participants for both global (86-96%) and most specific aspects of care (>75%). If consumers were dissatisfied with their overall care, they were significantly more likely to be aged 25-34 years of age. High levels of agreement among raters were found for global satisfaction (>85%) and most specific aspects of care (>70%), which provides some level of reassurance for staff. Open-ended questions showed that having effective treatment of sufficient duration and staff manner were most important to participants. High levels of satisfaction and agreement were found among consumers, family and referrers with CR. Open-ended questions identified which issues matter the most to key stakeholders, which may have implications for service evaluation tools.

The relationship between patient object relations and the therapeutic alliance in a naturalistic psychotherapy sample.

PubMed

Errázuriz, Paula; Constantino, Michael J; Calvo, Esteban

2015-09-01

This study examined the relationship between patients' object relations and interpersonal process in psychotherapy. Namely, we tested the hypothesis that the quality of patients' object relations is positively associated with both patient- and therapist-rated alliance quality. Psychotherapy was administered naturalistically, with quantitative data collection before and during treatment. Participants included 73 adult outpatients and 23 therapists at two mental health clinics. Using the Bell Object Relations and Reality Testing Inventory, we measured four dimensions of patients' object relations at baseline-alienation, insecure attachment, egocentricity, and social incompetence. Using the Working Alliance Inventory, we measured alliance from patient and therapist perspectives. Control variables included time, patient demographics, symptom severity, and clinic. We employed hierarchical linear modelling to analyse data with a nested structure, with 138 sessions at Level 1, 73 patients at Level 2, and 23 therapists at Level 3. Patient alienation and insecure attachment were associated with lower patient-rated alliance, while egocentricity was associated with higher patient-rated alliance. Patients' object relations were not significantly associated with therapist-rated alliance. On average, patients perceived the alliance more positively than their therapists, with a weak positive correlation between the alliance perspectives. The results suggest that object relation dimensions may be important patient characteristics for forecasting therapeutic relationship quality. They also call for more attention to differences between alliance rating perspectives. Treatment may benefit from more attention to the quality of patients' object relations. If patients present with high levels of alienation and insecure attachment, therapists may need to pay especially close attention to the therapeutic alliance, and prudently address any ruptures in its quality. When monitoring the alliance quality, it is important to consider that patients and therapists may have different perspectives. Therapists relying solely on their own perceptions are at risk of missing alliance difficulties, and patients' object relations may be uniquely predictive of their own sense of the alliance. Therefore, it may be helpful to ask patients in session and through standardized measures for feedback on how they perceive the goals and tasks of treatment and the emotional bond with their therapist. Again, any alliance tensions could then be addressed directly as a means to maintaining engagement in the service of better outcome. © 2014 The British Psychological Society.

Prosocial behavior: multilevel perspectives.

Penner, Louis A; Dovidio, John F; Piliavin, Jane A; Schroeder, David A

2005-01-01

Current research on prosocial behavior covers a broad and diverse range of phenomena. We argue that this large research literature can be best organized and understood from a multilevel perspective. We identify three levels of analysis of prosocial behavior: (a) the "meso" level--the study of helper-recipient dyads in the context of a specific situation; (b) the micro level--the study of the origins of prosocial tendencies and the sources of variation in these tendencies; and (c) the macro level--the study of prosocial actions that occur within the context of groups and large organizations. We present research at each level and discuss similarities and differences across levels. Finally, we consider ways in which theory and research at these three levels of analysis might be combined in future intra- and interdisciplinary research on prosocial behavior.

Using perspective to resolve reference: The impact of cognitive load and motivation.

PubMed

Cane, James E; Ferguson, Heather J; Apperly, Ian A

2017-04-01

Research has demonstrated a link between perspective taking and working memory. Here we used eye tracking to examine the time course with which working memory load (WML) influences perspective-taking ability in a referential communication task and how motivation to take another's perspective modulates these effects. In Experiment 1, where there was no reward or time pressure, listeners only showed evidence of incorporating perspective knowledge during integration of the target object but did not anticipate reference to this common ground object during the pretarget-noun period. WML did not affect this perspective use. In Experiment 2, where a reward for speed and accuracy was applied, listeners used perspective cues to disambiguate the target object from the competitor object from the earliest moments of processing (i.e., during the pretarget-noun period), but only under low load. Under high load, responses were comparable with the control condition, where both objects were in common ground. Furthermore, attempts to initiate perspective-relevant responses under high load led to impaired recall on the concurrent WML task, indicating that perspective-relevant responses were drawing on limited cognitive resources. These results show that when there is ambiguity, perspective cues guide rapid referential interpretation when there is sufficient motivation and sufficient cognitive resources.

Young women are often lured or forced into selling sex as a result of migrating from rural to urban areas to find work. In this setting, they are exposed to high-risk situations, which may leave them vulnerable to exploitation. Using interviews with young migrant women currently working as sex workers in northern Vietnam, we recorded the perspectives of their initiation into sex work and life as a sex worker. The study found that high levels of forced sex and sexual exploitation were experienced by the majority of the young women interviewed. The young women describe their entry into sex work, first sexual experience (intercourse), violence, and condom negotiation and use. Although access to health care was available, the young women perceived the stigma attached to sex work as a barrier to receiving health care, and thus, preferred health education and care from peers. Health education programs focusing on peer education and support are essential for protecting and empowering these young women. In addition, policies and programs must work toward effective strategies to protect young migrant women.

The present study investigated dynamic, longitudinal associations between depressive symptoms and marital processes. Two hundred ninety-six couples reported on marital satisfaction, marital conflict, and depressive symptoms yearly for three years. Observational measures of marital conflict were also collected. Results suggested that different domains of marital functioning related to husbands’ versus wives’ symptoms. For husbands, transactional relations between marital satisfaction and depressive symptoms were identified: high levels of depressive symptoms predicted subsequent decreases in marital satisfaction, and decreased marital satisfaction predicted subsequent elevations in symptoms over time. For wives, high levels of marital conflict predicted subsequent elevations in symptoms over time. Cross-partner results indicated that husbands’ depressive symptoms were also related to subsequent declines in wives’ marital satisfaction. Results are discussed with regard to theoretical perspectives on the marital functioning-depression link and directions for future research are outlined. PMID:21219284

Transcription as a Threat to Genome Integrity.

PubMed

Gaillard, Hélène; Aguilera, Andrés

2016-06-02

Genomes undergo different types of sporadic alterations, including DNA damage, point mutations, and genome rearrangements, that constitute the basis for evolution. However, these changes may occur at high levels as a result of cell pathology and trigger genome instability, a hallmark of cancer and a number of genetic diseases. In the last two decades, evidence has accumulated that transcription constitutes an important natural source of DNA metabolic errors that can compromise the integrity of the genome. Transcription can create the conditions for high levels of mutations and recombination by its ability to open the DNA structure and remodel chromatin, making it more accessible to DNA insulting agents, and by its ability to become a barrier to DNA replication. Here we review the molecular basis of such events from a mechanistic perspective with particular emphasis on the role of transcription as a genome instability determinant.

Perspectives on obesity and its treatment: health care providers and the general public in rural West Virginia and urban Baltimore.

2013-12-01

To determine and compare the perspectives of the general public and health care providers (HCPs) on obesity and its treatment in rural West Virginia (WV) and Baltimore, MD. Surveys were completed in both locations by the general public (WV: n = 200; Baltimore: n = 171) and HCPs (WV: n = 25; Baltimore: n = 15). BMI (body mass index) ≥ 30 (WV: n = 94; Baltimore: n = 58) was associated with a stronger belief in the heritability of obesity and with the ability to control obesity by controlling food cost, compared with those with normal BMI (WV: n = 42; Baltimore: n = 57). Those with a high school education (WV: n = 112; Baltimore: n = 113) were less likely to agree that obesity is a problem in the community and that proper diet and exercise are realistic expectations, compared with those with at least some higher education. Perspectives of HCPs differed significantly from the general public in both locations. Many differences in perspective on obesity exist between WV and Baltimore, within both populations, and between HCPs and the general public in both settings. A better understanding of patient views is important for effective obesity management. HCPs must consider each patient's level of understanding when discussing management and consequences of obesity. More time spent with patients who have less insight into their obesity may improve patient adherence with treatment and overall patient outcomes.

Sources of difficulty in assessment: example of PISA science items

Le Hebel, Florence; Montpied, Pascale; Tiberghien, Andrée; Fontanieu, Valérie

2017-03-01

The understanding of what makes a question difficult is a crucial concern in assessment. To study the difficulty of test questions, we focus on the case of PISA, which assesses to what degree 15-year-old students have acquired knowledge and skills essential for full participation in society. Our research question is to identify PISA science item characteristics that could influence the item's proficiency level. It is based on an a-priori item analysis and a statistical analysis. Results show that only the cognitive complexity and the format out of the different characteristics of PISA science items determined in our a-priori analysis have an explanatory power on an item's proficiency levels. The proficiency level cannot be explained by the dependence/independence of the information provided in the unit and/or item introduction and the competence. We conclude that in PISA, it appears possible to anticipate a high proficiency level, that is, students' low scores for items displaying a high cognitive complexity. In the case of a middle or low cognitive complexity level item, the cognitive complexity level is not sufficient to predict item difficulty. Other characteristics play a crucial role in item difficulty. We discuss anticipating the difficulties in assessment in a broader perspective.

2014-11-01

Using two 3-month diary studies and a large cross-sectional survey, we identified distinguishing features of adults with low versus high levels of moral character. Adults with high levels of moral character tend to: consider the needs and interests of others and how their actions affect other people (e.g., they have high levels of Honesty-Humility, empathic concern, guilt proneness); regulate their behavior effectively, specifically with reference to behaviors that have positive short-term consequences but negative long-term consequences (e.g., they have high levels of Conscientiousness, self-control, consideration of future consequences); and value being moral (e.g., they have high levels of moral identity-internalization). Cognitive moral development, Emotionality, and social value orientation were found to be relatively undiagnostic of moral character. Studies 1 and 2 revealed that employees with low moral character committed harmful work behaviors more frequently and helpful work behaviors less frequently than did employees with high moral character, according to their own admissions and coworkers' observations. Study 3 revealed that adults with low moral character committed more delinquent behavior and had more lenient attitudes toward unethical negotiation tactics than did adults with high moral character. By showing that individual differences have consistent, meaningful effects on employees' behaviors, after controlling for demographic variables (e.g., gender, age, income) and basic attributes of the work setting (e.g., enforcement of an ethics code), our results contest situationist perspectives that deemphasize the importance of personality. Moral people can be identified by self-reports in surveys, and these self-reports predict consequential behaviors months after the initial assessment.

The Impact of Time Perspective Latent Profiles on College Drinking: A Multidimensional Approach

Braitman, Abby L.; Henson, James M.

2015-01-01

Background Zimbardo and Boyd’s1 time perspective, or the temporal framework individuals use to process information, has been shown to predict health behaviors such as alcohol use. Previous studies supported the predictive validity of individual dimensions of time perspective, with some dimensions acting as protective factors and others as risk factors. However, some studies produced findings contrary to the general body of literature. In addition, time perspective is a multidimensional construct, and the combination of perspectives may be more predictive than individual dimensions in isolation; consequently, multidimensional profiles are a more accurate measure of individual differences and more appropriate for predicting health behaviors. Objectives The current study identified naturally occurring profiles of time perspective and examined their association with risky alcohol use. Methods Data were collected from a college student sample (n = 431, mean age = 20.41 years) using an online survey. Time perspective profiles were identified using latent profile analysis. Results Bootstrapped regression models identified a protective class that engaged in significantly less overall drinking (β = −0.254) as well as engaging in significantly less episodic high risk drinking (β = −0.274). There was also emerging evidence of a high risk time perspective profile that was linked to more overall drinking (β = 0.198) and engaging in more high risk drinking (β = 0.245), though these differences were not significant. Conclusions/Importance These findings support examining time perspective in a multidimensional framework rather than individual dimensions in isolation. Implications include identifying students most in need of interventions, and tailoring interventions to target temporal framing in decision-making. PMID:25607806

Introduction Handedness becomes important for students during their training period. Limited literature is available regarding the same. Aim The purpose of this study was to assess the dental practice perspectives and determine the hand preference and discomfort level among the Left-Handed (LH) clinical dental students. Materials and Methods A 30-item survey tool was used to conduct a cross-sectional survey among four successive LH cohorts (third and final year undergraduates, dental interns and postgraduates) in all the dental colleges of Bengaluru, Karnataka, India, during the year 2014. Results A total of 84 students completed the survey, response rate being 100%. About one-third (37%) reported that their institution was not properly equipped to accommodate LH students. Majority felt that LH dentists were at a higher risk of developing musculoskeletal complications. Mouth mirror handling showed equal distribution for handedness as compared to the other dental activities, whereas discomfort levels were negligible (“without any difficulty”). Dental practice perspective scores significantly correlated with the difficulty levels (r=-0.333, p<0.001). Conclusion Overall, the left-handers had a right dental practice perspective and their responses indicate a need to address their issues empathetically. PMID:27891465

This study assessed the effect of both embryonic thermal manipulation and dietary threonine level on the response of broilers inoculated with Salmonella Enteritidis, considering bacterial counts in the cecal contents, intestinal morphology, mucin and heat shock protein 70 gene expression, body weight and weight gain. Thermal manipulation was used from 11 days of incubation until hatch, defining three treatments: standard (37.7°C), continuous high temperature (38.7°C) and continuous low temperature (36.7°C). After hatch, chicks were distributed according to a 3x2+1 factorial arrangement (three temperatures and two threonine levels and one sham-inoculated control). At two days of age, all chicks were inoculated with Salmonella Enteritidis, except for the sham-inoculated control group. There was no interaction between the factors on any analyses. High temperature during incubation was able to reduce colonization by Salmonella Enteritidis in the first days, reducing both Salmonella counts and the number of positive birds. It also increased mucin expression and decreased Hsp70 expression compared with other inoculated groups. High temperature during incubation and high threonine level act independently to reduce the negative effects associated to Salmonella Enteritidis infection on intestinal morphology and performance, with results similar to sham-inoculated birds. The findings open new perspectives for practical strategies towards the pre-harvest Salmonella control in the poultry industry. PMID:26131553

There is growing appreciation of the importance of understanding the student perspective in Higher Education (HE) at both institutional and international levels. This is particularly important in Science, Technology, Engineering and Mathematics subjects such as Computer Science (CS) and Engineering in which industry needs are high but so are student dropout rates. An important factor to consider is the management of students' initial expectations of university study and career. This paper reports on a study of CS first-year students' expectations across three European countries using qualitative data from student surveys and essays. Expectation is examined from both short-term (topics to be studied) and long-term (career goals) perspectives. Tackling these issues will help paint a picture of computing education through students' eyes and explore their vision of its and their role in society. It will also help educators prepare students more effectively for university study and to improve the student experience.

The impact of globalization on subjectivities in Cuba: a gender perspective.

PubMed

Vega, Ania Pupo

2014-10-01

Globalization has created great transformations, not only in economics, but also in social and cultural relations, and has influenced political practices and governments. If not critically analysed, globalization may at first appear positive, but, in parallel with its development, high levels of poverty and exclusion have occurred and these may affect men and women differently. The objective of this article is to reveal the subjective or individual consequences that derive from globalization and the contexts it creates. This analysis centres on a gender perspective within a Cuban context and tries to challenge the prevailing view of the most poor and excluded groups. Psychiatry and psychology have a long way to go in the search for an understanding of the impact of globalization on human well-being, but critical thinking and the social sciences can offer an alternative to the transformation of this constructed order by giving prominence to people's own subjectivities and experiences.

Community Context and Child Health: A Human Capital Perspective.

PubMed

Smith-Greenaway, Emily

2017-09-01

Human capital theory suggests that education benefits individuals' and their children's health through the educational skills people acquire in school. This perspective may also be relevant at the community level: the greater presence of adults with educational skills in a community may be a reason why living in a more highly educated setting benefits health. I use Demographic and Health Survey data for 30 sub-Saharan African countries to investigate whether the percentage of literate adults-specifically women-in a community is associated with children's likelihood of survival. I characterize 13,785 African communities according to the prevalence of women who are literate. Multilevel discrete-time hazard models ( N = 536,781 children) confirm that living in a community where more women are literate is positively associated with child survival. The study supports the conceptualization of literacy, and potentially other educational skills, as forms of human capital that can spill over to benefit others.

Reverdy, V.

2016-12-01

In this discussion paper, we investigate the current and future status of numerical astrophysics and highlight key questions concerning the transition to the exascale era. We first discuss the fact that one of the main motivation behind high performance simulations should not be the reproduction of observational or experimental data, but the understanding of the emergence of complexity from fundamental laws. This motivation is put into perspective regarding the quest for more computational power and we argue that extra computational resources can be used to gain in abstraction. Then, the readiness level of present-day simulation codes in regard to upcoming exascale architecture is examined and two major challenges are raised concerning both the central role of data movement for performances and the growing complexity of codes. Software architecture is finally presented as a key component to make the most of upcoming architectures while solving original physics problems.

Collective hormonal profiles predict group performance.

Akinola, Modupe; Page-Gould, Elizabeth; Mehta, Pranjal H; Lu, Jackson G

2016-08-30

Prior research has shown that an individual's hormonal profile can influence the individual's social standing within a group. We introduce a different construct-a collective hormonal profile-which describes a group's hormonal make-up. We test whether a group's collective hormonal profile is related to its performance. Analysis of 370 individuals randomly assigned to work in 74 groups of three to six individuals revealed that group-level concentrations of testosterone and cortisol interact to predict a group's standing across groups. Groups with a collective hormonal profile characterized by high testosterone and low cortisol exhibited the highest performance. These collective hormonal level results remained reliable when controlling for personality traits and group-level variability in hormones. These findings support the hypothesis that groups with a biological propensity toward status pursuit (high testosterone) coupled with reduced stress-axis activity (low cortisol) engage in profit-maximizing decision-making. The current work extends the dual-hormone hypothesis to the collective level and provides a neurobiological perspective on the factors that determine who rises to the top across, not just within, social hierarchies.

2013-05-01

In the coming decades a changing climate and natural hazards will likely increase the vulnerability of agricultural and other food production infrastructures, posing increasing treats to industrialized and developing economies. While food security concerns affect us globally, the huge differences among countries in stocks, population size, poverty levels, economy, technologic development, transportation, health care systems and basic infrastructure will pose a much larger burden on populations in the developing and less developed world. In these economies, increase in the magnitude, duration and frequency of droughts, floods, hurricanes, rising sea levels, heat waves, thunderstorms, freezing events and other phenomena will pose severe costs on the population. For this presentation, we concentrate on a geophysical perspective of the problems, tools available, challenges and short and long-term perspectives. In many instances, a range of natural hazards are considered as unforeseen catastrophes, which suddenly affect without warning, resulting in major losses. Although the forecasting capacity in the different situations arising from climate change and natural hazards is still limited, there are a range of tools available to assess scenarios and forecast models for developing and implementing better mitigation strategies and prevention programs. Earth observation systems, geophysical instrumental networks, satellite observatories, improved understanding of phenomena, expanded global and regional databases, geographic information systems, higher capacity for computer modeling, numerical simulations, etc provide a scientific-technical framework for developing strategies. Hazard prevention and mitigation programs will result in high costs globally, however major costs and challenges concentrate on the less developed economies already affected by poverty, famines, health problems, social inequalities, poor infrastructure, low life expectancy, high population growth, inadequate education systems, immigration, economic crises, conflicts and other issues. Case history analyses and proposals for collaboration programs, know-how transfer and better use of geophysical tools, data, observatories and monitoring networks will be discussed.

There has been significant interest in the rhetoric of health security in recent years from both global and local perspectives. Understanding health in the context of disaster vulnerability presents an opportunity to examine how improved health might reduce the effects of environmental disasters and other crises. To this end, a project was implemented in Bangladesh to establish the potential of a health security approach for disaster resilience amongst people living in high risk environments. This paper explores what we might mean by health security through engaging community level perspectives in the southeast coastal belt of Bangladesh, an area prone to cyclone and flood. This has been examined with respect to variation in gender and wealth of households. Household surveys, interviews and focus group discussions were some of the methods used to collect data. The findings show that health related coping strategies and agentive capabilities in the context of impending crises vary from one micro-context to the next. This suggests a dynamic and integrative resilience that could be built on further, but one which remains remote from wider discourses on health security. Copyright 2010 Elsevier Ltd.

Community mental health nurses' perspectives of recovery-oriented practice.

PubMed

Gale, J; Marshall-Lucette, S

2012-05-01

Recovery-oriented practice, an approach aligned towards the service user perspective, has dominated the mental health care arena. Numerous studies have explored service users' accounts of the purpose, meaning and importance of 'recovery'; however, far less is known about healthcare staff confidence in its application to care delivery. A self-efficacy questionnaire and content analysis of nursing course documents were used to investigate a cohort of community mental health nurses' recovery-oriented practice and to determine the extent to which the current continuing professional development curriculum met their educational needs in this regard. Twenty-three community mental health nurses completed a self-efficacy questionnaire and 28 course documents were analysed. The findings revealed high levels of nurses' confidence in their understanding and ability to apply the recovery model and low levels of confidence were found in areas of social inclusion. The content analysis found only one course document that used the whole term 'recovery model'. The findings suggest a gap in the nurses' perceived ability and confidence in recovery-oriented practice with what is taught academically. Hence, nursing education needs to be more explicitly focused on the recovery model and its application to care delivery. © 2011 Blackwell Publishing.

An alter-centric perspective on employee innovation: The importance of alters' creative self-efficacy and network structure.

Grosser, Travis J; Venkataramani, Vijaya; Labianca, Giuseppe Joe

2017-09-01

While most social network studies of employee innovation behavior examine the focal employees' ("egos'") network structure, we employ an alter-centric perspective to study the personal characteristics of employees' network contacts-their "alters"-to better understand employee innovation. Specifically, we examine how the creative self-efficacy (CSE) and innovation behavior of employees' social network contacts affects their ability to generate and implement novel ideas. Hypotheses were tested using a sample of 144 employees in a U.S.-based product development organization. We find that the average CSE of alters in an employee's problem solving network is positively related to that employee's innovation behavior, with this relationship being mediated by these alters' average innovation behavior. The relationship between the alters' average innovation behavior and the employee's own innovation behavior is strengthened when these alters have less dense social networks. Post hoc results suggest that having network contacts with high levels of CSE also leads to an increase in ego's personal CSE 1 year later in cases where the employee's initial level of CSE was relatively low. Implications for theory and practice are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Design for interaction between humans and intelligent systems during real-time fault management

Initial results are reported to provide guidance and assistance for designers of intelligent systems and their human interfaces. The objective is to achieve more effective human-computer interaction (HCI) for real time fault management support systems. Studies of the development of intelligent fault management systems within NASA have resulted in a new perspective of the user. If the user is viewed as one of the subsystems in a heterogeneous, distributed system, system design becomes the design of a flexible architecture for accomplishing system tasks with both human and computer agents. HCI requirements and design should be distinguished from user interface (displays and controls) requirements and design. Effective HCI design for multi-agent systems requires explicit identification of activities and information that support coordination and communication between agents. The effects are characterized of HCI design on overall system design and approaches are identified to addressing HCI requirements in system design. The results include definition of (1) guidance based on information level requirements analysis of HCI, (2) high level requirements for a design methodology that integrates the HCI perspective into system design, and (3) requirements for embedding HCI design tools into intelligent system development environments.

To evaluate the cost-effectiveness of raising high-density lipoprotein cholesterol (HDL-C) with add-on nicotinic acid in statin-treated patients with coronary heart disease (CHD) and low HDL-C, from the French healthcare system perspective. Computer simulation economic modelling incorporating two decision analytic submodels was used. The first submodel generated a cohort of 2000 patients and simulated lipid changes using baseline characteristics and treatment effects from the ARterial Biology for the Investigation of the Treatment Effects of Reducing cholesterol (ARBITER 2) study. Prolonged-release (PR) nicotinic acid (1 g/day) was added in patients with HDL-C < 40 mg/dl (1.03 mmol/l) on statin alone. The second submodel used standard Markov techniques to evaluate long-term clinical and economic outcomes based on Framingham risk estimates. Direct medical costs were accounted from a third party payer perspective [2004 Euros (euro)] and discounted by 3%. Addition of PR nicotinic acid to statin therapy resulted in substantial health gain and increased life expectancy, at a cost well within the threshold (< 50,000 euros per life year gained) considered good value for money in Western Europe. Raising HDL-C by adding PR nicotinic acid to statin therapy in CHD patients was cost-effective in France at a level considered to represent good value for money by reimbursement authorities in Europe. This strategy was highly cost-effective in CHD patients with type 2 diabetes.

Implicit race bias is one factor that contributes to the underrepresentation of Black faculty. We designed the videogame "Fair Play" in which players assume the role of a Black graduate student named Jamal Davis. As Jamal, players experience subtle race bias while completing "quests" to obtain a science degree. We hypothesized that participants randomly assigned to play the game would have greater empathy for Jamal and lower implicit race bias than participants randomized to read narrative text describing Jamal's experience. University of Wisconsin-Madison graduate students were recruited via e-mail and randomly assigned to play "Fair Play" or read narrative text through an online link. Upon completion, participants took an Implicit Association Test to measure implicit bias and answered survey questions assessing empathy toward Jamal and awareness of bias. As hypothesized, gameplayers showed the least implicit bias but only when they also showed high empathy for Jamal (P=0.013). Gameplayers did not show greater empathy than text readers, and women in the text condition reported the greatest empathy for Jamal (P=0.008). However, high empathy only predicted lower levels of implicit bias among those who actively took Jamal's perspective through gameplay (P=0.014). A videogame in which players experience subtle race bias as a Black graduate student has the potential to reduce implicit bias, possibly because of a game's ability to foster empathy through active perspective taking.

Background The aim of this study was to assess the reasons for discontinuing or continuing olanzapine in patients with schizophrenia, from the perspectives of the patients and their clinicians. Methods The Reasons for Antipsychotic Discontinuation/Continuation (RAD) is a pair of questionnaires assessing these reasons from the perspectives of patients and their clinicians. Outpatients with schizophrenia (n = 199) who were not acutely ill participated in a 22-week open-label study of olanzapine from November 2006 to September 2008. Reasons for continuing or discontinuing olanzapine (on a five-point scale), along with the single most important reason and the top primary reasons, were identified. Concordance between reasons given by patients and clinicians was assessed. Results The top primary reasons for continuing olanzapine were patients’ perceptions of improvement, improvement of positive symptoms, and improved functioning. The study discontinuation rate was low (30.2%), and only a subset of patients who discontinued reported reasons for medication discontinuation. The top primary reasons for discontinuing olanzapine were insufficient improvement or worsening of positive symptoms, adverse events, and insufficient improvement or worsening of negative symptoms. Ratings given by patients and clinicians were highly concordant. Conclusion The main reason for continuing or discontinuing olanzapine appears to be medication efficacy, especially for positive symptoms. Reasons for medication discontinuation differ somewhat from reasons for continuation, with a high level of concordance between patient and clinician responses. PMID:22114469

Structured Professional Judgment (SPJ) approaches to violence risk assessment are increasingly being adopted into clinical practice in international forensic settings. The aim of this study was to examine the predictive validity of the Historical Clinical Risk -20 (HCR-20) violence risk assessment scale for outcome following transfers from high to medium security in a United Kingdom setting. The sample was predominately male and mentally ill and the majority of cases were detained under the criminal section of the Mental Health Act (1986). The HCR-20 was rated based on detailed case file information on 72 cases transferred from high to medium security. Outcomes were examined, independent of risk score, and cases were classed as "success or failure" based on established criteria. The mean length of follow up was 6 years. The total HCR-20 score was a robust predictor of failure at lower levels of security and return to high security. The Clinical and Risk management items contributed most to predictive accuracy. Although the HCR-20 was designed as a violence risk prediction tool our findings suggest it has potential utility in decisions to transfer patients from high to lower levels of security.

Control, responses and modularity of cellular regulatory networks: a control analysis perspective.

PubMed

Bruggeman, F J; Snoep, J L; Westerhoff, H V

Cells adapt to changes in environmental conditions through the concerted action of signalling, gene expression and metabolic subsystems. The authors will discuss a theoretical framework addressing such integrated systems. This 'hierarchical analysis' was first developed as an extension to a metabolic control analysis. It builds on the phenomenon that often the communication between signalling, gene expression and metabolic subsystems is almost exclusively via regulatory interactions and not via mass flow interactions. This allows for the treatment of the said subsystems as 'levels' in a hierarchical view of the organisation of the molecular reaction network of cells. Such a hierarchical approach has as a major advantage that levels can be analysed conceptually in isolation of each other (from a local intra-level perspective) and at a later stage integrated via their interactions (from a global inter-level perspective). Hereby, it allows for a modular approach with variable scope. A number of different approaches have been developed for the analysis of hierarchical systems, for example hierarchical control analysis and modular response analysis. The authors, here, review these methods and illustrate the strength of these types of analyses using a core model of a system with gene expression, metabolic and signal transduction levels.

Body Talk: Body Image Commentary on Queerty.com.

Schwartz, Joseph; Grimm, Josh

2016-08-01

In this study, we conducted a content analysis of 243 photographic images of men published on the gay male-oriented blog Queerty.com. We also analyzed 435 user-generated comments from a randomly selected 1-year sample. Focusing on images' body types, we found that the range of body types featured on the blog was quite narrow-the vast majority of images had very low levels of body fat and very high levels of muscularity. Users' body image-related comments typically endorsed and celebrated images; critiques of images were comparatively rare. Perspectives from objectification theory and social comparison theory suggest that the images and commentary found on the blog likely reinforce unhealthy body image in gay male communities.

Terrorism in Pakistan: a behavioral sciences perspective.

This article reviews the behavioral science perspectives of terrorism in Pakistan. It can be argued that Pakistan has gained worldwide attention for "terrorism" and its role in the "war against terrorism". The region is well placed geopolitically for economic successes but has been plagued by terrorism in various shapes and forms. A behavioral sciences perspective of terrorism is an attempt to explain it in this part of the world as a complex interplay of historical, geopolitical, anthropological and psychosocial factors and forces. Drawing from theories by Western scholars to explain the behavioral and cognitive underpinnings of a terrorist mind, the authors highlight the peculiarities of similar operatives at individual and group levels. Thorny issues related to the ethical and human right dimensions of the topic are visited from the unique perspective of a society challenged by schisms and divergence of opinions at individual, family, and community levels. The authors have attempted to minimize the political descriptions, although this cannot be avoided entirely, because of the nature of terrorism. Copyright © 2014 John Wiley & Sons, Ltd.

Dysphoric students show higher use of the observer perspective in their retrieval of positive versus negative autobiographical memories

Autobiographical memories are retrieved as images from either a field perspective or an observer perspective. The observer perspective is thought to dull emotion. Positive affect is blunted in depressed mood. Consequently, are positive events recalled from an observer perspective in depressed mood? We investigated the relationship between memory vantage perspective and depressive symptoms in a student sample. Participants completed the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986) and assessed the perspective accompanying each memory. The Beck Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996) and the Responses to Positive Affect questionnaire (RPA; Feldman, Joormann, & Johnson, 2008) were administered. The results showed a small positive association between depressive symptoms and the use of an observer perspective for positive autobiographical memories, but not for negative memories. Furthermore, comparing a subgroup with clinically significant symptom levels (dysphoric students) with non-dysphoric individuals revealed that dysphoric students used an observer perspective more for positive memories compared with negative memories. This was not the case for non-dysphoric students. The observer perspective in dysphorics was associated with a dampening cognitive style in response to positive experiences. PMID:23083015

To test a method of engaging consumers in research priority-setting using a quantitative approach and to determine consumer views on stroke research priorities for clinical practice recommendations with lower levels of evidence (Level III and Level IV) and expert consensus opinion as published in the Australian stroke clinical practice guidelines. Survey Urban community Eighteen stroke survivors (n = 12) and carers (n = 6) who were members of the "Working Aged Group - Stroke" (WAGS) consumer support group. Phase I: Participants were asked whether recommendations were "worth" researching ("yes" or "no"); and, if researched, what potential impact they likely would have on patient outcomes. Phase II: Participants were asked to rank recommendations rated by more than 75% of participants in Phase I as "worth" researching and "highly likely" or "likely" to generate research with a significant effect on patient outcomes (n = 13) in order of priority for future stroke research. All recommendations were rated by at least half (n = 9, 50%) of participants as "worth" researching. The majority (67% to 100%) rated all recommendations as "highly likely" or "likely" that research would have a significant effect on patient outcomes. Thirteen out of 20 recommendations were ranked for their research priorities. Recommendations under the topic heading Getting to hospital were ranked highest and Organization of care and Living with stroke were ranked as a lower priority for research. This study provided an example of how to involve consumers in research priority setting successfully using a quantitative approach. Stroke research priorities from the consumer perspective were different from those of health professionals, as published in the literature; thus, consumer opinion should be considered when setting research priorities.

Ethnic/racial discrimination moderates the effect of sleep quality on school engagement across high school.

PubMed

Dunbar, Margaret; Mirpuri, Sheena; Yip, Tiffany

2017-10-01

Previous research has indicated that school engagement tends to decline across high school. At the same time, sleep problems and exposure to social stressors such as ethnic/racial discrimination increase. The current study uses a biopsychosocial perspective to examine the interactive and prospective effects of sleep and discrimination on trajectories of academic performance. Growth curve models were used to explore changes in 6 waves of academic outcomes in a sample of 310 ethnically and racially diverse adolescents (mean age = 14.47 years, SD = .78, and 64.1% female). Ethnic/racial discrimination was assessed at Time 1 in a single survey. Sleep quality and duration were also assessed at Time 1 with daily diary surveys. School engagement and grades were reported every 6 months for 3 years. Higher self-reported sleep quality in the ninth grade was associated with higher levels of academic engagement at the start of high school. Ethnic/racial discrimination moderated the relationship between sleep quality and engagement such that adolescents reporting low levels of discrimination reported a steeper increase in engagement over time, whereas their peers reporting poor sleep quality and high levels of discrimination reported the worse engagement in the ninth grade and throughout high school. The combination of poor sleep quality and high levels of discrimination in ninth grade has downstream consequences for adolescent academic outcomes. This study applies the biopsychosocial model to understand the development and daily experiences of diverse adolescents. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Pricing the Services in Dynamic Environment: Agent Pricing Model

NASA Astrophysics Data System (ADS)

Žagar, Drago; Rupčić, Slavko; Rimac-Drlje, Snježana

New Internet applications and services as well as new user demands open many new issues concerning dynamic management of quality of service and price for received service, respectively. The main goals of Internet service providers are to maximize profit and maintain a negotiated quality of service. From the users' perspective the main goal is to maximize ratio of received QoS and costs of service. However, achieving these objectives could become very complex if we know that Internet service users might during the session become highly dynamic and proactive. This connotes changes in user profile or network provider/s profile caused by high level of user mobility or variable level of user demands. This paper proposes a new agent based pricing architecture for serving the highly dynamic customers in context of dynamic user/network environment. The proposed architecture comprises main aspects and basic parameters that will enable objective and transparent assessment of the costs for the service those Internet users receive while dynamically change QoS demands and cost profile.

Person-environment fit: everyday conflict and coparenting conflict in Mexican-origin teen mother families.

2015-01-01

The current study examined whether a match or mismatch between teen mothers' cultural orientation and the cultural context of the family (i.e., familial ethnic socialization) predicted mother-daughter everyday and coparenting conflict, and in turn, teen mothers' adjustment. Participants were 204 Mexican-origin teen mothers (M age = 16.81 years; SD = 1.00). Consistent with a person-environment fit perspective, findings indicated that a mismatch between teen mothers' cultural orientation (i.e., high mainstream cultural involvement) and the cultural context of the family (i.e., higher levels of familial ethnic socialization) predicted greater mother-daughter everyday conflict and coparenting conflict 1 year later. However, when there was a match (i.e., high levels of familial ethnic socialization for teen mothers with high Mexican orientation), familial ethnic socialization was not associated with mother-daughter conflict. In addition, mother-daughter conflict was positively associated with depressive symptoms and engagement in risky behaviors 1 year later among all teen mothers.

2014-09-01

Homozygous familial hypercholesterolaemia (HoFH) is a rare and severe hereditary lipid disorder that is typically associated with high serum levels of low-density lipoprotein cholesterol (LDL-C). Excessive exposure to high levels of LDL-C puts affected individuals at very high risk of premature onset coronary heart disease, and this considerably limits life expectancy. Although the clinical features and treatment of HoFH have been extensively researched, societal and socio-psychological impacts of the disease have not been reported to date. The current study was conducted to investigate the burden of disease and treatment from the patient's perspective by means of semi-structured interviews with 24 HoFH patients. The findings of the survey indicate that HoFH represents a considerable burden for patients, not only due to physical signs and limitations caused by the disease but also a number of psychosocial factors, treatment-related issues and impact on their education and employment situation.

Parents' perspectives on centralized cleft services for children: the development of a DCE questionnaire.

Ke, K M; Mackichan, F; Sandy, J R; Ness, A R; Hollingworth, W

2013-03-01

Incorporating user's perspectives in healthcare delivery is important. Simple questionnaires may not capture these as well as a discrete choice experiment (DCE) which enables the exploration of users' trade-offs between different service attributes. Qualitative methods are increasingly used to improve a DCE's face validity, but few studies adequately describe them. This paper describes the qualitative investigations in the development of a DCE questionnaire to elicit parents' perspectives on centralized services for children with cleft lip and palate. Semi-structured telephone interviews were conducted with 16 parents from across the UK, except Wales. Data analysis was carried out by the constant comparative method. Five attributes and their levels were inductively identified: usefulness and amount of information (four levels); staff attitude at cleft centres (two levels); continuity of care (two levels); personal costs of attending appointments (four levels); and cleft centres facilities (two levels). An unexpected finding was that parents' sense of responsibility towards their child made a 'willingness-to-travel' attribute unacceptable to them, but they were receptive to a 'willingness-to-pay' attribute. Using qualitative methods with service users in attribute development for a DCE helps to uncover issues that may not be apparent to researchers or health service staff. © 2012 John Wiley & Sons A/S.

The DUACS system produces, as part of the CNES/SALP project, and the Copernicus Marine Environment and Monitoring Service, high quality multimission altimetry Sea Level products for oceanographic applications, climate forecasting centers, geophysic and biology communities... These products consist in directly usable and easy to manipulate Level 3 (along-track cross-calibrated SLA) and Level 4 products (multiple sensors merged as maps or time series) and are available in global and regional version (Mediterranean Sea, Arctic, European Shelves …).The quality of the products is today limited by the altimeter technology "Low Resolution Mode" (LRM), and the lack of available observations. The launch of 2 new satellites in 2016, Jason-3 and Sentinel-3A, opens new perspectives. Using the global Synthetic Aperture Radar mode (SARM) coverage of S3A and optimizing the LRM altimeter processing (retracking, editing, ...) will allow us to fully exploit the fine-scale content of the altimetric missions. Thanks to this increase of real time altimetry observations we will also be able to improve Level-4 products by combining these new Level-3 products and new mapping methodology, such as dynamic interpolation. Finally these improvements will benefit to downstream products : geostrophic currents, Lagrangian products, eddy atlas… Overcoming all these challenges will provide major upgrades of Sea Level products to better fulfill user needs.

Perspective Taking Explains Gender Differences in Late Adolescents' Attitudes Toward Disadvantaged Groups.

Adolescents' attitudes toward disadvantaged groups are surprisingly understudied. What we know from these few studies is that adolescents' attitudes tend to become more favorable over time and that adolescent girls display more favorable attitudes than do adolescent boys. However, researchers have not offered explanations for why these effects occur. We proposed that changes in social-cognitive abilities that accompany adolescent development increase perspective taking and that the increased perspective taking facilitates more favorable attitudes toward disadvantaged groups. Because girls develop social-cognitive abilities earlier than boys, girls should show greater perspective taking and thus more positive attitudes toward disadvantaged groups than should boys. Importantly, we propose that these more positive attitudes are explained better by perspective taking than by gender. Participants were late adolescents (n = 803, 53.3 % female, ages 15-19) from high schools in north-central Florida (United States) participating in an ongoing, multi-wave study. Participants completed a measure of perspective-taking and reported their attitudes toward three disadvantaged groups (Black, gay, and poor people) during their third year of high school and, again, 6 months later during their fourth year of high school. Our findings provided strong support for our theorizing. Girls generally reported warmer attitudes than did boys toward disadvantaged groups, with the gender differences in warmth tending to diminish across time. Similarly, girls were higher than boys in perspective-taking abilities at both time points, although boys increased over time whereas girls did not. Crucially, perspective taking mediated observed gender differences in attitudes, suggesting that perspective taking is a mechanism for improving attitudes toward disadvantaged groups during late adolescence.

Perspectives on reasons for non-adherence to medication in persons with schizophrenia in Ethiopia: a qualitative study of patients, caregivers and health workers.

Levels of non-adherence to antipsychotic medication in persons with schizophrenia in rural African settings have been shown to be comparable to those found in high-income countries. Improved understanding of the underlying reasons will help to inform intervention strategies relevant to the context. A qualitative study was conducted among persons with schizophrenia (n = 24), their caregivers (n = 19), research field workers (n = 7) and health workers (n = 1) involved in the ongoing population-based cohort study, 'The Butajira Study on Course and Outcome of Schizophrenia and Bipolar Disorder', based in rural Ethiopia. Six focus group discussions and 9 in-depth interviews were conducted to elicit perspectives on non-adherence to antipsychotic medication. Thematic analysis was used to identify prominent perspectives. Predominant reasons for non-adherence specific to a low-income country setting included inadequate availability of food to counter appetite stimulation and the perceived strength of antipsychotic medications. The vital role of the family or other social support in the absence of a statutory social safety net was emphasised. Expectations of cure, rather than need for continuing care, were reported to contribute to non-adherence in the longer-term. Many of the factors associated with non-adherence in high-income countries were also considered important in Ethiopia, including lack of insight, failure to improve with treatment, medication side effects, substance abuse, stigma and dissatisfaction with the attitude of the care provider. This study identifies additional barriers to medication adherence faced by persons with schizophrenia in Ethiopia compared to those in high-income countries. In this era of scaling up of mental health care, greater attention to provision of social and financial assistance will potentially improve adherence and thereby enable patients to benefit more fully from medication.

Appraised leadership styles, psychosocial work factors, and musculoskeletal pain among public employees.

2007-10-01

The main aim of this study was to explore the associations between appraised leadership styles, psychosocial work factors and musculoskeletal pain among subordinates in four different public service sectors from an epidemiological perspective. A cross-sectional questionnaire study was conducted; data from 2,403 public sector employees in subordinate positions (86% women) were analysed. The appraised leadership styles were measured through items from a modified version of the CPE questionnaire (C change, P production/structure, E employee/relation). The structure validity of the CPE-model was examined by principal component analysis (PCA). Univariate and multivariate analyses of associations between levels of musculoskeletal pain and appraised leadership styles and with psychosocial work factors were conducted. Odds ratios (ORs) with confidence intervals (CIs) of 95% were used as a measure of associations. There were small variations in the appraisals of the immediate manager among the subordinates. However, the associations between musculoskeletal pain and leadership styles varied according to sector. Poor appraisals (low scores) on "change" and "employee relation" dimensions were associated with high levels of musculoskeletal pain in two sectors: home and health care services. In the domestic catering services, poor appraisals of managers in the "production/structure" dimension had the strongest association with high levels of pain. In general, poor appraisals of the "change" dimension was most strongly associated with high levels of musculoskeletal pain. "High work demands" had the strongest association with high levels of pain, particularly among the men. Poor appraisals of managers and their leadership styles were associated with high levels of musculoskeletal pain among both female and male subordinates in different public service sectors. There is therefore a great need of further studies of the mechanisms behind the relationships between the leadership styles and their impact on health among the genders.

The perspective of those assuming risk has become increasingly important to launch agencies. The IAASS white paper "An ICAO for Space?" proposed four ultimate goals of any international regulatory framework. The first of these was to "Ensure that citizens of all nations are equally protected from "unreasonable levels" of risk from overflight by missiles, launch vehicles and returning spacecraft". A key component of this concept is the issue of what is an "unreasonable level" of risk from the perspective of those assuming the risk.

Listening to middle-school Spanish-speaking English language learners: A qualitative study of their perspectives of science

NASA Astrophysics Data System (ADS)

Lopez-Ferrao, Julio E.

The purpose of this study is to contribute to the understanding and explanation of the science achievement gap between Spanish-speaking English language learners (ELLs) and their mainstream peers. The sample of purposefully selected participants (N = 23) included students representing eight Spanish-speaking countries who attended three middle schools (grades 6th-8th), 11 boys and 12 girls, with different years of schooling in the United States, English proficiency levels, and science achievement levels. Data gathering strategies included individual interviews with participants, classroom observations, and analysis of secondary data sources on students' English language proficiency and science achievement. Data interpretation strategies using a critical-interpretive perspective consisted of coding and narrative analysis, including analyses of excerpts and case studies. Two major findings emerge from the study: (1) An inverse relation between participants' number of years of exposure to science learning in an English-only learning environment and their science achievement levels; and (2) specific participant-identified problems, such as learning the science vocabulary, writing in science, the use of mathematics in science, and the lack of sense making in the science classroom. Key recommendations comprise: (1) Acknowledging the value of dual language education; (2) supporting the science-literacy connection; (3) ensuring high-quality science through research-informed instructional strategies; and (4) assessing ELLs' science achievement.

The neuro-immunological interface in an evolutionary perspective: the dynamic relationship between effector and recognition systems.

PubMed

Ottaviani, E; Valensin, S; Franceschi, C

1998-04-16

The evolutionary perspective indicates that an immune-neuroendocrine effector system integrating innate immunity, stress and inflammation is present in invertebrates. This defense network, centered on the macrophage and exerting primitive and highly promiscuous recognition units, is very effective, ancestral and appears to have been conserved throughout evolution from invertebrates to higher vertebrates. It would seem that there was a "big bang" in the recognition system of lower vertebrates, and T and B cell repertoires, MHC and antibodies suddenly appeared. We argue that this phenomenon is the counterpart of the increasing complexity of the internal circuitry and recognition units in the effector system. The immediate consequences were a progressive enlargement of the pathogen repertoire and new problems regarding self/not-self discrimination. Probably not by chance, a new organ appeared, capable of purging cells able of excessive self recognition. This organ, the thymus, appears to be the result of a well known evolutionary strategy of re-using pre-existing material (neuroendocrine cells and mediators constituting the thymic microenvironment). This bricolage at an organ level is similar to the effect we have already described at the level of molecules and functions of the defense network, and has a general counterpart at genetic level. Thus, in vertebrates, the conserved immune-neuroendocrine effector system remains of fundamental importance in defense against pathogens, while its efficiency has increased through synergy with the new, clonotipical recognition repertoire.

Meeting the educational and social needs of children with language impairment or autism spectrum disorder: the parents' perspectives.

2016-09-01

There is increasing interest in examining the perspectives of parents of children with special educational needs (SEN). Exploring the view of parents of a child with language impairment (LI) or autism spectrum disorder (ASD) is particularly important because of their high prevalence, at over 30% of children with SEN in England, and the increasing evidence of overlapping profiles of their needs. To examine the similarities and differences between the perspectives of parents of children with LI or ASD on three issues: (1) their child's educational progress, and their behavioural, emotional and social development; (2) the provision made to support their child's education and meet their SEN; and (3) their own involvement in decision-making about provision for their child. The parents of 129 children with LI (n = 76) or ASD (n = 53) were interviewed using a semi-structured protocol that gathered both quantitative data (parent ratings) and qualitative, in-depth explorations of their perspectives. There were no significant differences between the perspectives of parents of children with LI and parents of children with ASD with respect to their child's educational progress; the provision made to meet their child's educational needs; or their involvement in decision-making during the statutory assessment procedure, including the determination of a statement of SEN, and the current provision made by their child's school. Both parent groups were generally positive about these but parents of children with ASD were more concerned about their child's peer relationships. Parents whose child attended a mainstream school with a specialist resource tended to be more positive about the provision made than parents whose child was included individually into a mainstream school. Although previous research indicates that parents of children with ASD are overrepresented among those who express dissatisfaction with the provision made to meet their child's needs, this study indicates high levels of satisfaction and overlap between the perspectives of parents of children with LI or ASD regarding their child's educational progress and their own involvement in decision-making about the child's provision. The findings indicate the importance for policy and practice of focusing on identified needs rather than diagnostic category; and the importance of practitioners and administrators engaging meaningfully with parents in collaborative decision-making. © 2016 Royal College of Speech and Language Therapists.

Private medical education--the doctor's perspective.

PubMed

Abdul Hamid, A K

2000-08-01

The Government's decision to drastically and speedily increase the number of doctors in the country needs to be reviewed. The standard and quality of health care does not depend on the number of doctors, but on the improvement of the health care infrastructure. Increasing the number of government medical schools and increasing the intake of students should be done on a need-to basis, with the above perspective in mind. The selection criteria of candidates must not be compromised and the teaching staff must be adequate and experienced. The number of doctors should be gradually increased over the years in tandem with the development of the health care infrastructure and the deployment of doctors must be directed at providing equitable care to the people at all economic levels and geographic locations. The strength of academic staff in existing government medical schools must be upgraded to provide high level of teaching and research, perhaps reinforced with the recruitment of suitably qualified and experienced foreign teachers. The infrastructure of existing government medical schools must be upgraded to cater for the gradual increasing demand for more doctors as the country develops. The selection of candidates for the government medical schools must be based on merit and without undue emphasis on ethnic considerations, for it is only in the arena of fair competitiveness that excellence can be born. The considerations of merit in selection must include assessment of attitude, self-development, moral ethics and reasoning. If the above perspectives are fully appreciated, then there is really no requirement for private medical colleges in Malaysia.

We consider environments of modern subsurface martian regolith layer as possible habitats of the terrestrial like microorganisms. Recent experimental studies demonstrate that low atmospheric pressure, low temperature and high level of cosmic rays ionizing radiation are not able to sterilize the subsurface layer of Mars. Even nonextremofile microorganisms can reproduce in martian regolith using films of liquid water which are produced by absorption of water vapor of subsurface ice sublimation. Areas of possible seasonal subsurface water flow (recurring slope lineae, dark dune spots) and methane emission regions are discussed as perspective sites for discovering of modern life on Mars. Degradation of "biomarkers" (complex organic molecules and isotopic ratio 13C/12C) in martian soil under high level of cosmic rays radiation is analyzed. We show the ancient biomarkers are effectively destroyed within period 108 -109 years. As result, probability of its discovering in shallow subsurface martian layer is low.

Friendship group identification, multidimensional self-concept, and experience of developmental tasks in adolescence.

2006-08-01

This study applied a social identity perspective to the study of adolescent self-concept and social development. British adolescents aged 14-15 years (N=114) completed a questionnaire which asked them to: (i) rate their degree of identification with a school-based friendship group; (ii) complete a measure of multi-dimensional self-concept; and (iii) report their experiences of a variety of personal, relational and socio-institutional (e.g., achieving economic independence) developmental tasks. Compared to low identifiers, participants who were highly identified with a friendship group reported highest levels of self-esteem; and these differences were most marked in non-academic domains of self. High identifiers also displayed higher levels of general self-esteem and reported more positive experiences of personal and relational developmental tasks. The discussion focuses on the potential benefits to understanding of social developmental processes that can be derived from a consideration of adolescents' subjective appraisals of their peer relations.

Genesis of Preeclampsia: An Epidemiological Approach

There are analyzed some of the main aspects related to the causality of preeclampsia, privileging two types of models: the clinic model and the epidemiologic model, first one represented by the hypothesis of the reduced placental perfusion and the second one considering the epidemiologic findings related to the high levels of psychosocial stress and its association with preeclampsia. It is reasoned out the relevance of raising the causality of the disease from an interdisciplinary perspective, integrating the valuable information generated from both types, clinical and epidemiologic, and finally a tentative explanatory model of preeclampsia is proposed, the subclinical and sociocultural aspects that predispose and trigger the disease are emphasized making aspects to stand out: the importance of reduced placental perfusion as an indicator of individual risk, and the high levels of physiological stress, as a result of the unfavorable conditions of the psychosocial surroundings (indicator of population risk) of the pregnant women.

Can Sisyphus succeed? Getting U.S. high-level nuclear waste into a geological repository.

PubMed

North, D Warner

2013-01-01

The U.S. government has the obligation of managing the high-level radioactive waste from its defense activities and also, under existing law, from civilian nuclear power generation. This obligation is not being met. The January 2012 Final Report from the Blue Ribbon Commission on America's Nuclear Future provides commendable guidance but little that is new. The author, who served on the federal Nuclear Waste Technical Review Board from 1989 to 1994 and subsequently on the Board on Radioactive Waste Management of the National Research Council from 1994 to 1999, provides a perspective both on the Commission's recommendations and a potential path toward progress in meeting the federal obligation. By analogy to Sisyphus of Greek mythology, our nation needs to find a way to roll the rock to the top of the hill and have it stay there, rather than continuing to roll back down again. © 2012 Society for Risk Analysis.

Heart failure (HF) is a chronic disease of great clinical and economic significance for both the healthcare system and patients themselves. To determine the consumption of medical resources for treatment and care of HF patients and to estimate the related costs. The study involved 400 primary care practices and 396 specialist outpatient clinics, as well as 259 hospitals at all reference levels. The sample was representative and supplemented with patient interview data. Based on the consumption of particular resources and the unit costs of services in 2011, costs of care for HF patients in Poland were estimated. Separate analyses were conducted depending on the stage of the disease (according to NYHA classification I-IV). The public payer's perspective and a one year time horizon were adopted. Direct annual costs of an HF patient's treatment in Poland may range between PLN 3,373.23 and 7,739.49 (2011), the main cost item being hospitalisation. The total costs for the healthcare system could be as high as PLN 1,703 million, which is 3.16% of the National Health Fund's budget (Ex. rate from 05.03.2012: 1 EUR = 4.14 PLN). The costs of treating heart failure in Poland are high; proper allocation of resources to diagnostic procedures and treatment may contribute to rationalisation of the relevant expenditure.

Beyond "born this way?" reconsidering sexual orientation beliefs and attitudes.

Grzanka, Patrick R; Zeiders, Katharine H; Miles, Joseph R

2016-01-01

Previous research on heterosexuals' beliefs about sexual orientation (SO) has been limited in that it has generally examined heterosexuals' beliefs from an essentialist perspective. The recently developed Sexual Orientation Beliefs Scale (SOBS; Arseneau, Grzanka, Miles, & Fassinger, 2013) assesses multifarious "lay beliefs" about SO from essentialist, social constructionist, and constructivist perspectives. This study used the SOBS to explore latent group-based patterns in endorsement of these beliefs in 2 samples of undergraduate students: a mixed-gender sample (n = 379) and an all-women sample (n = 266). While previous research has posited that essentialist beliefs about the innateness of SO predict positive attitudes toward sexual minorities, our research contributes to a growing body of scholarship that suggests that biological essentialism should be considered in the context of other beliefs. Using a person-centered analytic strategy, we found that that college students fell into distinct patterns of SO beliefs that are more different on beliefs about the homogeneity, discreteness, and informativeness of SO categories than on beliefs about the naturalness of SO. Individuals with higher levels of endorsement on all 4 SOBS subscales (a group we named multidimensional essentialism) and those who were highest in discreteness, homogeneity, and informativeness beliefs (i.e., high-DHI) reported higher levels of homonegativity when compared with those who were high only in naturalness beliefs. We discuss the implications of these findings for counseling and psychotherapy about SO, as well educational and social interventions. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

To evaluate the perspective of ophthalmology residents in the US about their residency programs and compare the competency of residency programs to international competency levels set by the International Council of Ophthalmology (ICO). A cross-sectional web-based survey extracted from the ICO published competency standards was sent to program directors of ophthalmology residency programs in the US to forward it to current PGY-3, 4 residents, and residency graduates from 2011 to 2014. Eighty-seven responses were received, comprising 61 residents and 26 graduates. Most respondents were highly satisfied with their programs (93.6%). Clinic-based training was rated satisfactorily. Insufficient exposure to low-vision rehabilitation (38.5%), refraction and contact lenses prescription (38.5%), and vitreo-retinal surgeries (38.5%) was reported. Respondents were satisfied with their overall surgical experiences, with the vast majority (>83%) rating case volume, complexity, and variety as satisfactory or better. A significant group stated they had insufficient exposure to extra-capsular cataract extraction (26.3%), refractive surgery (19.7%), and orbital surgery (64.5%). All graduates surveyed passed their Ophthalmic Knowledge Assessment Program (OKAP) examinations, and 72% felt their residency programs adequately prepared them for the examinations. All respondents reported insufficient training in certain nonclinical areas, such as practice management, staffing, and administration skills. Ophthalmology residents in the US express high levels of satisfaction with their residency training programs. While most programs adequately address most ICO core objectives, certain curriculum modifications should be considered.

Integrated nanomaterials for extreme thermal management: a perspective for aerospace applications

Nanomaterials will play a disruptive role in next-generation thermal management for high power electronics in aerospace platforms. These high power and high frequency devices have been experiencing a paradigm shift toward designs that favor extreme integration and compaction. The reduction in form factor amplifies the intensity of the thermal loads and imposes extreme requirements on the thermal management architecture for reliable operation. In this perspective, we introduce the opportunities and challenges enabled by rationally integrating nanomaterials along the entire thermal resistance chain, beginning at the high heat flux source up to the system-level heat rejection. Using gallium nitride radio frequency devices as a case study, we employ a combination of viewpoints comprised of original research, academic literature, and industry adoption of emerging nanotechnologies being used to construct advanced thermal management architectures. We consider the benefits and challenges for nanomaterials along the entire thermal pathway from synthetic diamond and on-chip microfluidics at the heat source to vertically-aligned copper nanowires and nanoporous media along the heat rejection pathway. We then propose a vision for a materials-by-design approach to the rational engineering of complex nanostructures to achieve tunable property combinations on demand. These strategies offer a snapshot of the opportunities enabled by the rational design of nanomaterials to mitigate thermal constraints and approach the limits of performance in complex aerospace electronics.

Authentic research projects: Students' perspectives on the process, ownership, and benefits of doing research

NASA Astrophysics Data System (ADS)

Bernard, Warren

2005-11-01

Authentic research projects are one type of inquiry activity as defined by the American Association for the Advancement of Science (1993) and are a core component in science education reform movements. The purpose of this study was to examine high school students' perspectives of an authentic research project. The context for this study was a local Science and Engineering Fair (SEF) that involved students from a Metro-Atlanta public high school. This study provided information about this type of activity from the student's perspective, an emic viewpoint. In this qualitative study, demographic information was used for the purposeful selection of fourteen students making up the study sample. In this descriptive ethnography, data were collected via an open-ended survey, three individual interviews, a web log, and a group interview. Interviews were audio taped and conducted according to the protocol established by Lincoln and Guba (1998). Transcripts of the interviews, web logs, and survey responses were coded and analyzed by the constant comparative method as described by Glaser and Strauss (1965). Reliability and validity were achieved through member checks and triangulation. Using Gowin's Vee diagram (1981) as a theoretical framework for analysis, themes emerged describing the students' research experience. The themes included the students' initial reactions, difficulty getting started, accepting ownership of their project, growing interest, acknowledged benefits of the research experience, and a reflective look back at their experience. Overall, students described the authentic research experience as a worthwhile activity. The implications of the study are two-fold. At the practitioner level, teachers should engage students in research, but should do so in a manner that maximizes authenticity. Examples may include having students present a formal prospectus and work with a scientist mentor. For Science Educators in teacher preparation programs, there should be an experience with authentic research for pre-service teachers during the certification program. Future research may focus on the students' perspectives of ownership through the process of the authentic research and teachers' perspectives of the authentic research experience.

Dimensions of control as related to work organization, stress, and health.

PubMed

Aronsson, G

1989-01-01

The aim of this article is to examine how increased worker control-on the individual as well as on collective level-may be a means to reduce the risk of work environment-related stress and diseases. Control is also an important element in socialization processes and in work reform activities directed to a democratization of working life. The concept of control connects a number of research perspectives. It deals with the individual and the collective level, as well as the relationship between them, and it may be a bridge between a social psychological and a psychobiological perspective. In this article, the author considers the control concept primarily from a stress perspective, but also examines how production techniques, legislation, and management strategies create the structure of control at work.

Factorial and Item-Level Invariance of a Principal Perspectives Survey: German and U.S. Principals.

PubMed

Wang, Chuang; Hancock, Dawson R; Muller, Ulrich

This study examined the factorial and item-level invariance of a survey of principals' job satisfaction and perspectives about reasons and barriers to becoming a principal with a sample of US principals and another sample of German principals. Confirmatory factor analysis (CFA) and differential item functioning (DIF) analysis were employed at the test and item level, respectively. A single group CFA was conducted first, and the model was found to fit the data collected. The factorial invariance between the German and the US principals was tested through three steps: (a) configural invariance; (b) measurement invariance; and (c) structural invariance. The results suggest that the survey is a viable measure of principals' job satisfaction and perspectives about reasons and barriers to becoming a principal because principals from two different cultures shared a similar pattern on all three constructs. The DIF analysis further revealed that 22 out of the 28 items functioned similarly between German and US principals.

Who speaks? Who looks? Who feels? Point of view in autobiographical narratives.

PubMed

Habermas, Tilmann

2006-04-01

In this paper, the author aims to substantiate Freud's claim that neurotic illness creates gaps in autobiographical narratives in terms of the narrator's stating and inducing perspectives. He sketches out the role of narrative perspective and the joint taking of a shared perspective by analyst and patient in psychoanalytic therapy. He introduces four ways of representing perspectives in narratives. Three degrees of narrative distortion are exemplified by three excerpts from life narratives and explored in terms of narrative perspective representation. The most comprehensive perspective representation is achieved in the first example by explicitly stating the present perspective of the narrator as well as the past perspective of the story's protagonist by use of mental verbs. In the second narrative, exclusive use of linguistic forms for inducing the protagonist's perspective both overwhelms the narrator and gives the listener an incomplete picture of what happened. Inconsistent motives, denial of responsibility and omission of detail render the third narrative even more difficult to follow. The author discusses the clinical significance of this exploratory analysis of perspectives in narratives in terms of claiming responsibility for one's past action and of level of defence mechanisms, and by highlighting the emotional impact on listeners, which the author suggests is the stronger the more perspectives are left out. He discusses analogies to countertransference. The analysis of narrative perspectives offers an approach for systematic research in psychoanalytic practice.

There is wide concern about polycyclic aromatic hydrocarbons (PAHs) because of their carcinogenic and mutagenic potential. The coking industry is an important source of PAHs. In this study, 36 arable soil samples, a sensitive medium from the perspective of food safety and health, were collected from one of the largest coke production bases in China. The concentration of total 21 PAHs ranged from 294 to 1665 ng g(-1), with a mean of 822±355 ng g(-1). Approximately 60% of the soil samples were heavily polluted with the level higher than 600 ng g(-1). Particularly high abundances of high molecular weight PAHs were found, and the calculated BaPeq was as high as 54.3 ng g(-1). Soil PAH levels were positively correlated with soil organic matter content. The soil PAHs were from complex mixture sources, and high-temperature pyrogenic sources were most likely responsible for the heavy PAH contamination. Effective control strategies and probable remediation approaches should be proposed to improve soil quality. Copyright © 2015 Elsevier Ltd. All rights reserved.

[A Survey of the Factors of Influence and Interventional Strategies for Breast Cancer Survivors' Transition Care Across Multiple Theoretical Perspectives].

Chao, Yu-Huan; Lee, Tzu-I; Sheu, Shuh-Jen

2018-02-01

Breast cancer significantly threatens the life of women, while the adverse effects of cancer treatment degrade quality of life and psychological well-being. The quality of transitional care following the completion of treatment significantly affects the ability of breast cancer patients to transition successfully into survivorship. This paper introduces multiple theoretical perspectives and provides an overview of the tenets of each in order to identify the positions of breast cancer survivors and to highlight the factors and strategies that influence their transitional care. The theoretical perspectives that are introduced include the social-ecological model, transition theory, and the strengths perspective. In order to improve the holistic care of women with breast cancer, factors relevant to transition are categorized into the individual, interpersonal, organizational, community, and policy levels. Furthermore, empirical interventions, which are based on the respective advantages of the various levels of the social-ecological model, are proposed in order to conform to the sociocultural context and clinical practices. Healthcare providers should leverage the strengths and resources at each level to develop feasible strategies and to provide quality of care in order to assist breast cancer patients to transition successfully from treatment to survivorship and to holistically improve their subsequent quality of life and function.

Manipulating recall vantage perspective of intrusive memories in dysphoria.

PubMed

Williams, Alishia D; Moulds, Michelle L

2008-10-01

The current study attempted to experimentally manipulate mode of recall (field, observer perspective) in a sample of mildly dysphoric participants (N=134) who reported a distressing intrusive memory of negative autobiographical event. Specifically, the current study sought to ascertain whether shifting participants into a converse perspective would have differential effects on the reported experience of their memory. Results indicated that shifting participants from a field to an observer perspective resulted in decreased experiential ratings: specifically, reduced distress and vividness. Also, as anticipated, the converse shift in perspective (from observer to field) did not lead to a corresponding increase in experiential ratings, but did result in reduced ratings of observation and a trend was observed for decreased levels of detachment. The findings support the notion that recall perspective has a functional role in the regulation of intrusion-related distress and represents a cognitive avoidance mechanism.

The aim of this study was to predict acute postsurgical pain and coping with pain following surgery based on preoperative time perspectives. Time perspective is a basic dimension of psychological time. It is a tendency to focus on a particular time area: the past, the present and the future. Seventy-six patients completed measures of time perspective and pain 24 h before abdominal surgery. During the 3 days after surgery, measures of pain and coping with pain were completed. We performed hierarchical regression analyses to identify predictors of acute postsurgical pain and how patients cope with it. These analyses suggested that a preoperative past-negative time perspective can be a predictor of postoperative pain level and catastrophizing after surgery. The findings of our study indicate the importance of time perspective, especially the past perspective, in dealing with postoperative pain. Our research indicates that a preoperative past-negative time perspective is a significant predictor of acute postsurgical pain intensity and the strongest predictor of pain catastrophizing. © 2016 European Pain Federation - EFIC®.

Perspectives of patients with non-insulin-treated type 2 diabetes on self-monitoring of blood glucose: A qualitative study.

Chen, Chen-Mei; Hung, Li-Chen; Chen, Yang-Lin; Yeh, Mei Chang

2018-04-01

To explore experiences of self-monitoring of blood glucose among patients with non-insulin-treated type 2 diabetes. Self-monitoring of blood glucose is essential to diabetes care and facilitates glycaemic control. Patients' perspectives of self-monitoring of blood glucose have seldom been discussed in the literature, and engagement in self-monitoring of blood glucose is consistently low. The descriptive phenomenological method was used. Purposive sampling was conducted to recruit participants from the endocrinology departments of medical institutions in Taiwan based on the following criteria: (i) having a medical diagnosis of type 2 diabetes, (ii) not being treated with insulin, (iii) having engaged in self-monitoring of blood glucose at least once within the preceding 6 months, (iv) being at least 20 years old and (v) not having any major mental or cognitive disorders. Data were collected in outpatient consultation rooms, the participants' homes and other settings where the participants felt secure and comfortable. In-depth interviews were conducted to collect data from 16 patients with diabetes. The participants perceived that lifestyle affected blood glucose levels and did not know how to handle high or low blood glucose levels. Their willingness to continue self-monitoring of blood glucose depended on whether healthcare professionals checked or discussed their blood glucose levels with them. The patients' knowledge regarding blood glucose variation and healthcare professionals' attitudes affected the patients' self-monitoring of blood glucose behaviours. The empirical findings illustrated self-monitoring of blood glucose experiences and recommended that healthcare professionals' closely attend to patients' requirements and responses to diabetes and incorporate the self-monitoring of blood glucose into therapy plans. Healthcare professionals should reinforce patients' knowledge on appropriate responses to high and low blood glucose levels, intervene appropriately, discuss self-monitoring of blood glucose results with patients and track these results. © 2017 John Wiley & Sons Ltd.

MDMA and heightened cortisol: a neurohormonal perspective on the pregnancy outcomes of mothers used 'Ecstasy' during pregnancy.

PubMed

2014-01-01

The illicit recreational drug 3,4-methylenedioxymethamphetamine (MDMA) or Ecstasy has strong neurohormonal effects. When taken by recreational users at dance clubs and raves, it can generate an 800% increase in the stress hormone cortisol, whereas drug-free users show chronically raised levels of cortisol. The aim here is to critically debate this neurohormonal influence for the children of pregnant MDMA-using mothers. High levels of cortisol are known to be damaging for neuropsychobiological well-being in adult humans. MDMA can damage foetal development in laboratory animals, and the prospective Drugs and Infancy Study was established to monitor the effects of MDMA taken recreationally by pregnant women. The Drugs and Infancy Study revealed that young mothers, who took MDMA during the first trimester of pregnancy, gave birth to babies with significant gross psychomotor retardation. These mothers would have experienced high levels of cortisol due to Ecstasy/MDMA use, and since cortisol can cross the placenta, this is likely to have also occurred in the foetus. In terms of causation, the developmental problems may reflect a combination of neurotransmitter and neurohormonal effects on the hypothalamic-pituitary-adrenal axis, with serotonergic activity being influenced by the high levels of cortisol.

Nurse managers (NMs) play an important role promoting evidence-based practice (EBP) on clinical units within hospitals. However, there is a dearth of research focused on NM perspectives about institutional contextual factors to support the goal of EBP on the clinical unit. The purpose of this article is to identify contextual factors described by NMs to drive change and facilitate EBP at the unit level, comparing and contrasting these perspectives across nursing units. This study employed a qualitative descriptive design using interviews with nine NMs who were participating in a large effectiveness study. To stratify the sample, NMs were selected from nursing units designated as high or low performing based on implementation of EBP interventions, scores on the Meyer and Goes research use scale, and fall rates. Descriptive content analysis was used to identify themes that reflect the complex nature of infrastructure described by NMs and contextual influences that supported or hindered their promotion of EBP on the clinical unit. NMs perceived workplace culture, structure, and resources as facilitators or barriers to empowering nurses under their supervision to use EBP and drive change. A workplace culture that provides clear communication of EBP goals or regulatory changes, direct contact with CEOs, and clear expectations supported NMs in their promotion of EBP on their units. High-performing unit NMs described a structure that included nursing-specific committees, allowing nurses to drive change and EBP from within the unit. NMs from high-performing units were more likely to articulate internal resources, such as quality-monitoring departments, as critical to the implementation of EBP on their units. This study contributes to a deeper understanding of institutional contextual factors that can be used to support NMs in their efforts to drive EBP changes at the unit level.

Stability and Reactivity: Positive and Negative Aspects for Nanoparticle Processing.

Xu, Liang; Liang, Hai-Wei; Yang, Yuan; Yu, Shu-Hong

Nanoparticles exist far from the equilibrium state due to their high surface energy. Nanoparticles are therefore extremely unstable and easily change themselves or react with active substances to reach a relatively stable state in some cases. This causes desired changes or undesired changes to nanoparticles and thus makes them exhibit a high reactivity and a poor stability. Such dual nature (poor stability and high reactivity) of nanoparticles may result in both negative and positive effects for nanoparticle processing. However, the existing studies mainly focus on the high reactivity of nanoparticles, whereas their poor stability has been neglected or considered inconsequential. In fact, in some cases the unstable process, which is derived from the poor stability of nanoparticles, offers an opportunity to design and fabricate unique nanomaterials, such as by chemically transforming the "captured" intermediate nanostructures during a changing process, assembling destabilized nanoparticles into larger ordered assemblies, or shrinking/processing pristine materials into the desired size or shape via selective etching. In this review, we aim to present the stability and reactivity of nanoparticles on three levels: the foundation, concrete manifestations, and applications. We start with a brief introduction of dangling bonds and the surface chemistry of nanoparticles. Then, concrete manifestations of the poor stability and high reactivity of nanoparticles are presented from four perspectives: dispersion stability, thermal stability, structural stability, and chemical stability/reactivity. Next, we discuss some issues regarding the stability and reactivity of nanomaterials during applications. Finally, conclusions and perspectives on this field are presented.

Previous research has been devoted to the study of perceptual (e.g., number of depth cues) and cognitive (e.g., instructional set) factors that influence veridical size perception in perspective displays. However, considering that perspective displays have utility in high workload environments that often induce high arousal (e.g., aircraft cockpits), the present study sought to examine the effect of observers’ emotional state on the ability to perceive and judge veridical size. Within a dual-task paradigm, observers’ ability to make accurate size judgments was examined under conditions of induced emotional state (positive, negative, neutral) and high and low workload. Results showed that participantsmore » in both positive and negative induced emotional states were slower to make accurate size judgments than those not under induced emotional arousal. Results suggest that emotional state is an important factor that influences visual performance on perspective displays and is worthy of further study.« less

Universal Health Coverage’s evolving location in the post-2015 development agenda: Key informant perspectives within multilateral and related agencies during the first phase of post-2015 negotiations

Brolan, Claire E; Hill, Peter S

2016-01-01

In 2001, technocrats from four multilateral organizations selected the Millennium Development Goals mainly from the previous decade of United Nations (UN) summits and conferences. Few accounts are available of that significant yet cloistered synthesis process: none contemporaneous. In contrast, this study examines health’s evolving location in the first-phase of the next iteration of global development goal negotiation for the post-2015 era, through the synchronous perspectives of representatives of key multilateral and related organizations. As part of the Go4Health Project, in-depth interviews were conducted in mid-2013 with 57 professionals working on health and the post-2015 agenda within multilaterals and related agencies. Using discourse analysis, this article reports the results and analysis of a Universal Health Coverage (UHC) theme: contextualizing UHC’s positioning within the post-2015 agenda-setting process immediately after the Global Thematic Consultation on Health and High-Level Panel of Eminent Persons on the Post-2015 Development Agenda (High-Level Panel) released their post-2015 health and development goal aspirations in April and May 2013, respectively. After the findings from the interview data analysis are presented, the Results will be discussed drawing on Shiffman and Smith (Generation of political priority for global health initiatives: a framework and case study of maternal mortality. The Lancet 2007; 370: 1370–79) agenda-setting analytical framework (examining ideas, issues, actors and political context), modified by Benzian et al. (2011). Although more participants support the High-Level Panel’s May 2013 report’s proposal—‘Ensure Healthy Lives’—as the next umbrella health goal, they nevertheless still emphasize the need for UHC to achieve this and thus be incorporated as part of its trajectory. Despite UHC’s conceptual ambiguity and cursory mention in the High-Level Panel report, its proponents suggest its re-emergence will occur in forthcoming State led post-2015 negotiations. However, the final post-2015 SDG framework for UN General Assembly endorsement in September 2015 confirms UHC’s continued distillation in negotiations, as UHC ultimately became one of a litany of targets within the proposed global health goal.

The economic assessment of the impacts of storm surges and sea-level rise in coastal cities requires high-level information on the damage and protection costs associated with varying flood heights. We provide a systematically and consistently calculated dataset of macroscale damage and protection cost curves for the 600 largest European coastal cities opening the perspective for a wide range of applications. Offering the first comprehensive dataset to include the costs of dike protection, we provide the underpinning information to run comparative assessments of costs and benefits of coastal adaptation. Aggregate cost curves for coastal flooding at the city-level are commonly regarded as by-products of impact assessments and are generally not published as a standalone dataset. Hence, our work also aims at initiating a more critical discussion on the availability and derivation of cost curves.

Richter, Andreas W; Hirst, Giles; van Knippenberg, Daan; Baer, Markus

2012-11-01

We propose a cross-level perspective on the relation between creative self-efficacy and individual creativity in which team informational resources, comprising both shared "knowledge of who knows what" (KWKW) and functional background diversity, benefit the creativity of individuals more with higher creative self-efficacy. To test our hypotheses, we conducted a multi-level study with 176 employees working in 34 research and development teams of a multinational company in 4 countries. In support of our hypotheses, the link between creative self-efficacy and individual creativity was more positive with greater shared KWKW, and this interactive effect was pronounced for teams of high rather than low functional background diversity. We discuss implications for the study of creative self-efficacy in team contexts. (c) 2012 APA, all rights reserved.

Cross-sectional studies have revealed that high levels of optimism can protect against high levels of posttraumatic stress after exposure to trauma. However, this is the first study to explore (a) the protective role of optimism in a longitudinal perspective and (b) optimism's protective effects on specific symptom clusters within the posttraumatic stress symptomatology. This study used prospective survey data from ministerial employees (n = 256) collected approximately 1, 2, and 3 years after the 2011 Oslo bombing. To examine relationships between optimism and development of posttraumatic stress, we applied a series of latent growth curve analyses of both overall posttraumatic stress and the 5 clusters within the posttraumatic stress symptomatology (intrusions, avoidance, numbing, dysphoric arousal, and anxious arousal) with predictors and interaction terms. The results showed that levels of exposure and optimism had main effects on starting levels of all clusters of posttraumatic stress. In addition, optimism had a protective-stabilizing effect on starting levels of avoidance, numbing, and dysphoric arousal. No associations between optimism and rate of change in symptoms clusters were found. These results suggest that optimism may help to neutralize the effects of high exposure on levels of symptoms of avoidance, numbing, and dysphoric arousal but not on the symptoms of intrusions and anxious arousal. Thus, individuals high in optimism still experience intrusions and anxious arousal after trauma, but may be better equipped to cope with these so they do not develop into avoidance, numbing and dyshorical arousal.

2017-10-01

Bus services that can help meet almost every bus user's needs are the goals of bus operators. Despite such an idealistic view, the operators themselves, users and even the local authorities have been found to hold different views about the quality of service that the bus should deliver. As the users i.e., customers are considered as important stakeholders, understanding their characteristics, profile and pattern is very crucial. To this end, the present study has attempted to gauge the perspectives of all the above-mentioned stakeholders. For the users, a customer satisfaction survey was employed to look into the relative influence of service attributes. In addition, surveys were also administered to bus operators and local authorities to study their perspectives in relation to this matter. 450 randomly selected respondents were surveyed. Identification of the service level was analyzed through the Likert scale whereas the perspectives of the operators and authorities were dealt with through mean value Analysis. Specifically, this study aims to identify the crucial attributes in determining the quality of the bus services. Findings of the study indicated that different attributes were selected by users, operators and authorities, which clearly enlightened the variations of the important attributes in determining the level of bus service quality. In its attempt to compare the service level attributes from three perspectives, this study has helped advance better improvement and strategies for the urban public bus operators and planners, in addition to the authorities in delivering user-friendly bus services by taking into account the local context, user profile and demographic characteristics.

To identify, from the perspectives of nurses, occupational stressors and ways in which they may be reduced. Nurses commonly experience high levels of occupational stress, with negative consequences for their physical and psychological health, health-care organisations and community. There is minimal research on reducing occupational stress. Six focus groups were conducted with 38 registered nurses using a qualitative exploratory approach. Participants were asked to identify sources of occupational stress and possible workplace initiatives to reduce stress. Sources of occupational stress were: high workloads, unavailability of doctors, unsupportive management, human resource issues, interpersonal issues, patients' relatives, shift work, car parking, handover procedures, no common area for nurses, not progressing at work and patient mental health. Suggestions for reduction included: workload modification, non-ward-based initiatives, changing shift hours, forwarding suggestions for change, music, special events, organisational development, ensuring nurses get breaks, massage therapists, acknowledgement from management and leadership within wards. The findings highlight the need to understand local perspectives and the importance of involving nurses in identifying initiatives to reduce occupational stress. Health-care environments can be enhanced through local understanding of the occupational stressors and productively engaging nurses in developing stress reduction initiatives. Nurse managers must facilitate such processes. © 2013 Blackwell Publishing Ltd.

Objectives. The aim of this study is to estimate the economic burden associated with the management of periodontitis in Malaysia from the societal perspective. Methods. We estimated the economic burden of periodontitis by combining the disease prevalence with its treatment costs. We estimated treatment costs (with 2012 value of Malaysian Ringgit) using the cost-of-illness approach and included both direct and indirect costs. We used the National Oral Health Survey for Adults (2010) data to estimate the prevalence of periodontitis and 2010 national census data to estimate the adult population at risk for periodontitis. Results. The economic burden of managing all cases of periodontitis at the national level from the societal perspective was approximately MYR 32.5 billion, accounting for 3.83% of the 2012 Gross Domestic Product of the country. It would cost the nation MYR 18.3 billion to treat patients with moderate periodontitis and MYR 13.7 billion to treat patients with severe periodontitis. Conclusion. The economic burden of periodontitis in Malaysia is substantial and comparable with that of other chronic diseases in the country. This is attributable to its high prevalence and high cost of treatment. Judicious application of promotive, preventive, and curative approaches to periodontitis management is decidedly warranted.

Time perspective is a cultural behavioral concept that reflects individuals' orientations or attitudes toward the past, present, or future. Individuals' time perspectives influence their choices regarding daily activities. Time perspective is an important consideration when teaching adolescents about the importance of being physically active. However, little is known about the relationship between time perspective and physical activity among adolescents. The purpose of this study was to determine the time perspective of central Appalachian adolescents and explore the relationship between time perspective and physical activity. This study was guided by The theory of planned behavior (TPB). One hundred and ninety-three students completed surveys to examine time perspective and physical activity behaviors. Data were collected in one school. Results of this study can inform school nurses and high school guidance counselors about the importance of promoting a future-oriented time perspective to improve physical activity and educational outcomes.

Bladder cancer is the most expensive cancer per capita to treat in the US healthcare system. Substantial costs associated with the diagnosis, management and surveillance of bladder cancer account for the bulk of the expense; yet, for that cost, patients may not receive high-quality care. Herein the authors review the sources of expenditure associated with bladder cancer care, review population-level analyses of the quality of bladder cancer care in the USA, and discuss opportunities for quality improvement that may yield greater value for men and women newly diagnosed with bladder cancer.

RNA replicons - a new approach for influenza virus immunoprophylaxis.

Zimmer, Gert

2010-02-01

RNA replicons are derived from either positive- or negative-strand RNA viruses. They represent disabled virus vectors that are not only avirulent, but also unable to revert to virulence. Due to autonomous RNA replication, RNA replicons are able to drive high level, cytosolic expression of recombinant antigens stimulating both the humoral and the cellular branch of the immune system. This review provides an update on the available literature covering influenza virus vaccines based on RNA replicons. The pros and cons of these vaccine strategies will be discussed and future perspectives disclosed.

Gene delivery for cancer therapy.

Gene therapy has potential in the treatment of human cancers. However, its clinical implication has only achieved little success due to the lack of an efficient gene delivery system. A major hurdle in the current available approaches is in the ability to transduce target tissues at very high efficiencies that ultimately lead to therapeutic levels of transgene expression. This review outlines the characteristics and utilities of several available gene delivery systems, including their advantages and drawbacks in the context of cancer treatment. A perspective of existing challenges and future directions is also included.

β-Lactam resistance in Haemophilus parasuis is an emerging phenomenon that has not yet been characterized from a molecular perspective. Clinical high-level β-lactam-resistant isolates from Spain bore a novel plasmid, pB1000, expressing a functionally active ROB-1 β-lactamase. Pulsed-field gel electrophoresis was applied for the first time to H. parasuis and showed that β-lactam resistance is due to clonal spread of a resistant strain, BB1018, bearing pB1000.

Assessing quality of care from the patient's perspective has changed from patient satisfaction to the more general term patient experience, as satisfaction measures turned out to be less discriminative due to high scores. Literature describes four to ten dimensions of patient experience, tailored to specific conditions or types of care. Given the administrative burden on patients, less dimensions and items could increase feasibility. Ten dimensions of patient experiences with physical therapy (PT) were proposed in the Netherlands in a consensus-based process with patients, physical therapists, health insurers, and policy makers. The aim of this paper is to detect the number of dimensions from data of a field study using factor analysis at item level. A web-based survey yielded data of 2,221 patients from 52 PT practices on 41 items. Principal component factor analysis at item level was used to assess the proposed distinction between the ten dimensions. Factor analysis revealed two dimensions: 'personal interaction' and 'practice organisation'. The dimension 'patient reported outcome' was artificially established. The three dimensions 'personal interaction' (14 items) (median(practice level) = 91.1; IQR = 2.4), 'practice organisation' (9 items) (median(practice level) = 88.9; IQR = 6.0) and 'outcome' (3 items) (median(practice level) = 80.6; IQR = 19.5) reduced the number of dimensions from ten to three and the number of items by more than a third. Factor analysis revealed three dimensions and achieved an item reduction of more than a third. It is a relevant step in the development process of a quality measurement tool to reduce respondent burden, increase clarity, and promote feasibility.

To determine the quality and content of English language Internet information about juvenile idiopathic arthritis (JIA) from the perspectives of consumers and healthcare professionals. Key words relevant to JIA were searched across 10 search engines. Quality of information was appraised independently by 2 health professionals, 1 young adult with JIA, and a parent using the DISCERN tool. Concordance of the website content (i.e., accuracy and completeness) with available evidence about the management of JIA was determined. Readability was determined using Flesch-Kincaid grade level and Reading Ease Score. Out of the 3000 Web pages accessed, only 58 unique sites met the inclusion criteria. Of these sites only 16 had DISCERN scores above 50% (indicating fair quality). These sites were then rated by consumers. Most sites targeted parents and none were specifically developed for youth with JIA. The overall quality of website information was fair, with a mean DISCERN quality rating score of 48.92 out of 75 (+/- 6.56, range 34.0-59.5). Overall completeness of sites was 9.07 out of 16 (+/- 2.28, range 5.25-13.25) and accuracy was 3.09 out of 4 (+/- 0.86, range 2-4), indicating a moderate level of accuracy. Average Flesch-Kincaid grade level and Reading Ease Score were 11.48 (+/- 0.74, range 10.1-12.0) and 36.36 (+/- 10.86, range 6.30-48.1), respectively, indicating that the material was difficult to read. Our study highlights the paucity of high quality Internet health information at an appropriate reading level for youth with JIA and their parents.

This study presents quantitative, sociological models designed to account for cross-national variation in infant mortality rates. We consider variables linked to four different theoretical perspectives: the economic modernization, social modernization, political modernization, and dependency perspectives. The study is based on a panel regression analysis of a sample of 59 developing countries. Our preliminary analysis based on additive models replicates prior studies to the extent that we find that indicators linked to economic and social modernization have beneficial effects on infant mortality. We also find support for hypotheses derived from the dependency perspective suggesting that multinational corporate penetration fosters higher levels of infant mortality. Subsequent analysis incorporating interaction effects suggest that the level of political democracy conditions the effects of dependency relationships based upon exports, investments from multinational corporations, and international lending institutions. Transnational economic linkages associated with exports, multinational corporations, and international lending institutions adversely affect infant mortality more strongly at lower levels of democracy than at higher levels of democracy: intranational, political factors interact with the international, economic forces to affect infant mortality. We conclude with some brief policy recommendations and suggestions for the direction of future research.

"Engendering" Agenda 21: gender equality and water resource management: five years after Rio.

Hannan-andersson, C

1997-01-01

Agenda 21 acknowledges women's role in natural resources management at the local level and emphasizes the need for more women in senior positions to contribute positively to the implementation of environmental policy. This article assesses Agenda 21's approach to gender equality and its achievements. A few explicit references to women and water resource management (WRM) without consideration on the gender implications of the WRM policies and strategies were noted. The macro-oriented, technology-focused and supply-oriented approach of Agenda 21 on WRM hinders the inclusion of a gender perspective. There are two levels of implications of gender-blind intervention in relation to WRM: the issue of social justice and rights, and the negative impact of the neglect of gender inequality on overall planning and success of interventions. The inclusion of a gender perspective at policy and planning levels to facilitate the resolution of inconsistencies, as well as the importance of water sources and patterns of use knowledge for adequate policy development and planning was suggested. It is important that the WRM principle application utilize a sociocultural and gender perspective at both community and household levels before decisions are made on WRM interventions.

Despite progress in policy changes, tobacco use rates are still high in the military. Little is known about the views of those who create and implement tobacco control policies within the Department of Defense. These individuals determine what policy initiatives will be developed, prioritized, and implemented. We conducted key informant interviews with 16 service-level policy leaders (PLs) and 36 installation-level tobacco control managers (TCMs). PLs and TCMs believed that line leadership view tobacco control as a low priority that has minimal impact on successful mission completion. They also identified cultural factors that perpetuate tobacco use, such as low cost and easy accessibility to tobacco, smoke breaks, and uneven or unknown enforcement of current tobacco policies.

Stem cell research and the intellectual property derived from it, because of its potential to completely transform health care, demand an especially high level of consideration from business and patent prosecution perspectives. As with other revolutionary technologies, ordinary risks are amplified (e.g., litigation), and ordinarily irrelevant considerations may become important (e.g., heightened level of both domestic and foreign legislative risk). In the first part of this article, general strategies for patent prosecutors such as several prosecution considerations and methods for accelerating patent prosecution process are presented. In the second part, patent prosecution challenges of stem cell-related patents and possible solutions are discussed. In the final part, ethical and public policy issues particular to stem cell-related and other biotechnological inventions are summarized.

Predictors of stress of parents of a child with cancer: a Jordanian perspective.

Masa'Deh, Rami; Collier, Jacqueline; Hall, Carol; Alhalaiqa, Fadwa

2013-09-04

Most paediatric oncology studies agree that being parents of a child with cancer is an emotionally stressful event. Although an increasing number of studies have investigated psychological stress of parents of a child with cancer, few of these studies have included both parents or investigated the predictors of high stress levels for the mothers and the fathers. Moreover, studies published over the last few decades were limited to Western countries and have shown inconsistent findings about parental perceived stress whose children have cancer. This study explored differences in predictors of perceived stress between Jordanian mothers and fathers of children with cancer. This study involved a survey of 300 couples parenting a child with cancer. Participants answered the Arabic version of the Perceived Stress Scale 10-items, demographic and characteristics check list questionnaires. The main aims were to measure perceived stress levels for mothers and fathers, explore the predictors associated with high perceived stress levels and make a comparison between them. Mothers reported significantly higher stress levels than fathers (p<0.001), with a large effect size (0.30). Some of the factors associated with mothers and fathers high stress levels affected both parents whereas employment status affected only fathers' stress levels. These findings indicate the need to work with the mothers and the fathers with a child with cancer in Jordan to recognise their psychological needs at the time of diagnosis and followed by on-going psychological support for both parents.

Background: Most paediatric oncology studies agree that being parents of a child with cancer is an emotionally stressful event. Although an increasing number of studies have investigated psychological stress of parents of a child with cancer, few of these studies have included both parents or investigated the predictors of high stress levels for the mothers and the fathers. Moreover, studies published over the last few decades were limited to Western countries and have shown inconsistent findings about parental perceived stress whose children have cancer. This study explored differences in predictors of perceived stress between Jordanian mothers and fathers of children with cancer. Methods: This study involved a survey of 300 couples parenting a child with cancer. Participants answered the Arabic version of the Perceived Stress Scale 10-items, demographic and characteristics check list questionnaires. The main aims were to measure perceived stress levels for mothers and fathers, explore the predictors associated with high perceived stress levels and make a comparison between them. Findings: Mothers reported significantly higher stress levels than fathers (p<0.001), with a large effect size (0.30). Some of the factors associated with mothers and fathers high stress levels affected both parents whereas employment status affected only fathers’ stress levels. Conclusions: These findings indicate the need to work with the mothers and the fathers with a child with cancer in Jordan to recognise their psychological needs at the time of diagnosis and followed by on-going psychological support for both parents.

The perspectives of Caribbean high school students' experiences in American science classrooms

The purpose of this study was to describe the perspectives of Caribbean high school students' experiences in American science classrooms. Research suggests that psychological, cultural, and socioeconomic perspectives influence the science experiences of African Americans or Blacks; the result of which is under-representation (Lewis et al., 2000). Nonetheless, what is uncertain is if these and other perspectives are similar to the science experiences of Caribbeans who also are majority black by race and rank as the 3 rd largest immigrant population in America's schools (Suarez-Orozco, 2000). Questions guiding this study were: (1) What are the perspectives of Caribbean high school students' experiences in American science classrooms? (2) What can we learn from the perspectives of Caribbean high school students' science experiences that may address issues of participation and interest; consequently, influencing the overall performance of ethnic minorities in school science? Sociocultural theory provides the framework for the analysis of the study. Four Caribbean born students in an American high school participated in this naturalistic qualitative research. A constant comparative method was used to categorize and analyze the data and uncover meaningful patterns that emerged from the four interviews and written documents. Although there were similarities between African Americans' science experiences as documented in the literature and that of Caribbeans in this study, the Caribbean participants relied on prior native experiences to dictate their perspectives of their science experiences in America. According to Caribbean students, American science high schools classrooms utilize an objective style of assessments; are characterized by a lack of teacher support; allow behavioral problems in the classroom; and function through different communication styles than the native Caribbean science classroom environment. This study implies science educators should be sensitive to the sociocultural nuances of Caribbeans, as well as to all other students. Educators should also understand and value students' individual backgrounds, cultural patterns, and specific influences which impinge students in science and may result in underachievement. In addition, educators should not only discuss issues of under-representation in science but also they should begin to initiate the implementation of strategies addressed in this study in order to bring awareness and resolution to these pressing issues.
