There is emerging evidence that the encoding of visual information and the maintenance of this information in a temporarily accessible state in working memory rely on the same neural mechanisms. A consequence of this overlap is that atypical forms of perception should influence working memory. We examined this by investigating whether having grapheme–color synesthesia, a condition characterized by the involuntary experience of color photisms when reading or representing graphemes, would confer benefits on working memory. Two competing hypotheses propose that superior memory in synesthesia results from information being coded in two information channels (dual-coding) or from superior dimension-specific visual processing (enhanced processing). We discriminated between these hypotheses in three n-back experiments in which controls and synesthetes viewed inducer and non-inducer graphemes and maintained color or grapheme information in working memory. Synesthetes displayed superior color working memory than controls for both grapheme types, whereas the two groups did not differ in grapheme working memory. Further analyses excluded the possibilities of enhanced working memory among synesthetes being due to greater color discrimination, stimulus color familiarity, or bidirectionality. These results reveal enhanced dimension-specific visual working memory in this population and supply further evidence for a close relationship between sensory processing and the maintenance of sensory information in working memory.

Background: Children with specific language impairment (SLI) often experience difficulties in the recall and repetition of verbal information. Archibald and Gathercole (2006) suggested that children with SLI are vulnerable across two separate components of a tripartite model of working memory (Baddeley and Hitch 1974). However, the hierarchical…

2014-04-08

Working memory for color has been the central focus in an ongoing debate concerning the structure and limits of visual working memory. Within this area, the delayed estimation task has played a key role. An implicit assumption in color working memory research generally, and delayed estimation in particular, is that the fidelity of memory does not depend on color value (and, relatedly, that experimental colors have been sampled homogeneously with respect to discriminability). This assumption is reflected in the common practice of collapsing across trials with different target colors when estimating memory precision and other model parameters. Here we investigated whether or not this assumption is secure. To do so, we conducted delayed estimation experiments following standard practice with a memory load of one. We discovered that different target colors evoked response distributions that differed widely in dispersion and that these stimulus-specific response properties were correlated across observers. Subsequent experiments demonstrated that stimulus-specific responses persist under higher memory loads and that at least part of the specificity arises in perception and is eventually propagated to working memory. Posthoc stimulus measurement revealed that rendered stimuli differed from nominal stimuli in both chromaticity and luminance. We discuss the implications of these deviations for both our results and those from other working memory studies.

The division of paid and unpaid labor in families continues to be highly gendered with men doing more paid work and women doing more unpaid care work. This is especially true for life stages with young children. Our study investigates the subjective experience of demands in the work and the private domain and the experience of work-life balance across family-life stages as a consequence of this gendered division of labor. We used data from a survey study on work-life issues and health in four large companies in Switzerland (N = 3664). In line with our hypotheses, subjective work and private demands were predicted by an interaction of family-life stages and gender. Specifically, during the primary child-rearing family-life stages, women experience more private demands than men while men experience more work demands, regardless of level of employment. Furthermore, women who work part time experience more work-life balance than women who work full time and more than men who work part or full time during the primary child-rearing family-life stages. Results are discussed in terms of a gendered work-life experience across the life course and the need for part-time work for both genders. Finally, conclusions are drawn concerning our results' implications for public health considerations.

Examining variation in working memory capacity and retrieval in cued recall.

PubMed

Unsworth, Nash

2009-05-01

Two experiments examined the notion that individual differences in working memory capacity (WMC) are partially due to differences in search set size in cued recall. High and low WMC individuals performed variants of a cued recall task with either unrelated cue words (Experiment 1) or specific cue phrases (Experiment 2). Across both experiments low WMC individuals recalled fewer items, made more errors, and had longer correct recall latencies than high WMC individuals. Cross-experimental analyses suggested that providing participants with more specific cues decreased the size of the search set, leading to better recall overall. However, these effects were equivalent for high and low WMC. It is argued that these results are consistent with a search model framework in which low WMC individuals search through a larger set of items than high WMC individuals.

Influence of affective valence on working memory processes.

PubMed

Gotoh, Fumiko

2008-02-01

Recent research has revealed widespread effects of emotion on cognitive function and memory. However, the influence of affective valence on working or short-term memory remains largely unexplored. In two experiments, the present study examined the predictions that negative words would capture attention, that attention would be difficult to disengage from such negative words, and that the cost of attention switching would increase the time required to update information in working memory. Participants switched between two concurrent working memory tasks: word recognition and a working memory digit updating task. Experiment 1 showed substantial switching cost for negative words, relative to neutral words. Experiment 2 replicated the first experiment, using a self-report measure of anxiety to examine if switching cost is a function of an anxiety-related attention bias. Results did not support this hypothesis. In addition, Experiment 2 revealed switch costs for positive words without the effect of the attention bias from anxiety. The present study demonstrates the effect of affective valence on a specific component of working memory. Moreover, findings suggest why affective valence effects on working memory have not been found in previous research.

Cancer patients can experience work-specific cognitive symptoms post return to work (RTW). The study aims to: 1) describe the course of work-specific cognitive symptoms in the first 18 months post RTW, and 2) examine the associations of work characteristics, fatigue and depressive symptoms with work-specific cognitive symptoms over time. This study used data from the 18-months longitudinal "Work Life after Cancer" cohort. The Cognitive Symptom Checklist-Work, Dutch Version (CSC-W DV) was used to measure work-specific cognitive symptoms. Linear mixed models were performed to examine the course of work-specific cognitive symptoms during 18 months follow-up; linear regression analyses with generalised estimating equations (GEE) were used to examine associations over time. Working cancer patients diagnosed with different cancer types were included (n=378). Work-specific cognitive symptoms were stable over 18 months. At baseline, cancer patients reported more working memory symptoms (M=31.9, CI=23.1, 26.4) compared to executive function symptoms (M=19.3; CI=17.6, 20.9). Cancer patients holding a job with both manual and non-manual tasks reported less work-specific cognitive symptoms (unstandardized regression coefficient b=-4.80; CI=-7.76, -1.83) over time, compared to cancer patients with a non-manual job. Over time, higher depressive symptoms were related to experiencing more overall work-specific cognitive symptoms (b=1.27; CI=1.00, 1.55) and a higher fatigue score was related to more working memory symptoms (b=0.13; CI=0.04, 0.23). Job type should be considered when looking at work-specific cognitive symptoms over time in working cancer patients. To reduce work-specific cognitive symptoms, interventions targeted at fatigue and depressive symptoms might be promising. This article is protected by copyright. All rights reserved.

Although music therapists may work with a variety of professionals in interdisciplinary teams, there is a lack of information about the specific nature of their work with speech-language pathologists (SLPs). Using an Internet-based tool, Board Certified Music Therapists (n = 1834, 1675 deliverable) were surveyed regarding their work with speech-language pathologists and experiences with augmentative and alternative communication (AAC). Specifically, participants were asked about: (a) demographics; (b) populations worked with professionally; (c) past and present work with speech-language pathologists; (d) goals addressed; (e) benefits and challenges encountered; and (f) work with AAC. Responses (N = 847) indicated the majority of participants (73.6%) had worked with SLPs at some point in various roles and in various settings. Fewer participants reported currently working with SLPs (42.8%), although 50.1% reported currently working with someone requiring some form of AAC. Participants reported a mean level of expertise with AAC of 3.9 on a scale of 1-7. Sharing knowledge was noted as a top benefit of working with SLPs, while scheduling was reported as the most frequent challenge. Other benefits and challenges as well as future research directions are discussed.

Ups and downs of the expatriate experience? Understanding work adjustment trajectories and career outcomes.

2016-04-01

We examine changes in work adjustment among 179 expatriates from 3 multinational organizations from predeparture through the first 9 months of a new international assignment. Our 10-wave results challenge classic U-shaped theories of expatriate adjustment (e.g., Torbiorn, 1982). Consistent with uncertainty reduction theory, our results instead suggest that expatriates typically experience a gradual increase in work adjustment over time. Two resources that expatriates bring to their assignments (previous culture-specific work experience and core self-evaluations) moderate the trajectory of work adjustment. Trajectory of adjustment predicts Month 9 career instrumentality and turnover intention, as well as career advancement (job promotion) 1.5 years further. Implications for theory, as well as for changes in expatriate management practices, are discussed. (c) 2016 APA, all rights reserved).

Considerations of education in the field of biophotonics in engineering: the experience of the subject fundamentals of biophotonics

NASA Astrophysics Data System (ADS)

Fanjul-Vélez, F.; Arce-Diego, J. L.

2017-12-01

Education in the field of photonics is usually somehow complex due to the fact that most of the programs include just a few subjects on the field, apart from specific Master programs in Photonics. There are also specific doctorate programs dealing with photonics. Apart from the problems shared with photonics in education in general, biophotonics specifically needs an interdisciplinary approach between biomedical and technical or scientific fields. In this work, we present our education experience in teaching the subject Fundamentals of Biophotonics, intended preferentially to engineering Bachelor and Master degrees students, but also to science and medicine students. First it was necessary to join a teaching group coming from the scientific technical and medical fields, working together in the subject. This task was easier as our research group, the Applied Optical Techniques group, had previous contacts and experience in working with medicine professors and medical doctors at hospitals. The orientation of the subject, intended for both technical and medical students, has to be carefully selected. All this information could be employed by other education institutions willing to implement studies on biomedical optics.

2006-08-20

The practice of oncology can be a source of both great satisfaction and great stress. Although many oncologists experience burnout, depression, and dissatisfaction with work, others experience tremendous career satisfaction and achieve a high overall quality of life. Identifying professional goals, optimizing career fit, identifying and managing stressors specific to practice type, and achieving the optimal personal work-life balance can increase the likelihood of individual oncologists' achieving personal and professional satisfaction. In this article, we will explore how oncologists can accomplish these tasks and will examine several pervasive professional myths that often distort perspective. The article concludes in a conversation with four oncologists regarding what they find most meaningful about their work, how they manage career-specific stressors, and how they achieve balance between their personal and professional lives.

Naeraa, N

1987-05-01

The purpose of this work was to encourage students to base their laboratory report work on guidelines reflecting a quality criterion set, previously derived from the functional role of the various sections in scientific papers. The materials were developed by a trial-and-error approach and comprise learning objectives, a parallel structure of manual and reports, general and specific report guidelines and a new common starting experiment. The principal contents are presented, followed by an account of the author's experience with them. Most of the author's students now follow the guidelines. Their conclusions are affected by difficulties in adjusting expected results with due regard to the specific conditions of the experimental subject or to their own deviations from the experimental or analytical procedures prescribed in the manual. Also, problems in interpreting data unbiased by explicit expectations are evident, although a clear distinction between expected and actual results has been helpful for them in seeing the relationship between experiments and textbook contents more clearly, and thus in understanding the hypothetico-deductive approach.

The aim of this study was to explore the experiences of and influences on work ability in young workers related to their work and life situation. In a qualitative study of a strategic sample of 12 young female and 12 young male workers, aged 25-30 years, in work or recently left work, recruited from the 5-year follow-up of a Swedish cohort, semi-structured interviews were performed to explore the experiences of work ability in these young workers. Systematic text condensation inspired by phenomenology was used in the analysis. Work ability was experienced as complex, consisting of four themes, each with three subthemes. To be alert and have energy, to possess sufficient education, skills and working life experience and experience meaningfulness and engagement in work, were perceived to be fundamental for work ability and were seen as the worker's own responsibility. Moreover, work ability can be improved or reduced by the psychosocial work climate, the work organization and the private life. Optimal work ability was experienced when all themes integrated in a positive way. Work ability was experienced as the worker's own responsibility that could be influenced by work circumstances and private life. To promote good work ability among young workers, work ability has to be understood in its specific context. Whether the understanding of work ability found in this study is explicit for the group of young adults needs to be explored in a more general population in further research.

Visuo-spatial processing and executive functions in children with specific language impairment

PubMed Central

Marton, Klara

2007-01-01

Background Individual differences in complex working memory tasks reflect simultaneous processing, executive functions, and attention control. Children with specific language impairment (SLI) show a deficit in verbal working memory tasks that involve simultaneous processing of information. Aims The purpose of the study was to examine executive functions and visuo-spatial processing and working memory in children with SLI and in their typically developing peers (TLD). Experiment 1 included 40 children with SLI (age=5;3–6;10) and 40 children with TLD (age=5;3–6;7); Experiment 2 included 25 children with SLI (age=8;2–11;2) and 25 children with TLD (age=8;3–11;0). It was examined whether the difficulties that children with SLI show in verbal working memory tasks are also present in visuo-spatial working memory. Methods & Procedures In Experiment 1, children's performance was measured with three visuo-spatial processing tasks: space visualization, position in space, and design copying. The stimuli in Experiment 2 were two widely used neuropsychological tests: the Wisconsin Card Sorting Test — 64 (WCST-64) and the Tower of London test (TOL). Outcomes & Results In Experiment 1, children with SLI performed more poorly than their age-matched peers in all visuo-spatial working memory tasks. There was a subgroup within the SLI group that included children whose parents and teachers reported a weakness in the child's attention control. These children showed particular difficulties in the tasks of Experiment 1. The results support Engle's attention control theory: individuals need good attention control to perform well in visuo-spatial working memory tasks. In Experiment 2, the children with SLI produced more perseverative errors and more rule violations than their peers. Conclusions Executive functions have a great impact on SLI children's working memory performance, regardless of domain. Tasks that require an increased amount of attention control and executive functions are more difficult for the children with SLI than for their peers. Most children with SLI scored either below average or in the low average range on the neuropsychological tests that measured executive functions. PMID:17852522

Breaking cycles of risk: The mitigating role of maternal working memory in associations among socioeconomic status, early caregiving, and children's working memory.

PubMed

Suor, Jennifer H; Sturge-Apple, Melissa L; Skibo, Michael A

2017-10-01

Previous research has documented socioeconomic-related disparities in children's working memory; however, the putative proximal caregiving mechanisms that underlie these effects are less known. The present study sought to examine whether the effects of early family socioeconomic status on children's working memory were mediated through experiences of caregiving, specifically maternal harsh discipline and responsiveness. Utilizing a psychobiological framework of parenting, the present study also tested whether maternal working memory moderated the initial paths between the family socioeconomic context and maternal harsh discipline and responsiveness in the mediation model. The sample included 185 socioeconomically diverse mother-child dyads assessed when children were 3.5 and 5 years old. Results demonstrated that maternal harsh discipline was a unique mediator of the relation between early experiences of family socioeconomic adversity and lower working memory outcomes in children. Individual differences in maternal working memory emerged as a potent individual difference factor that specifically moderated the mediating influence of harsh discipline within low socioeconomic contexts. The findings have implications for early risk processes underlying deficits in child working memory outcomes and potential targets for parent-child interventions.

Cosmic Microwave Background Polarization and Inflation

NASA Technical Reports Server (NTRS)

Chuss, David T.

2011-01-01

Measurements of the cosmic microwave background (CMB) offer a means to explore the universe at a very early epoch. Specifically, if the universe went through a brief period of exponential expansion called inflation as current data suggest, gravitational waves from this period would polarize the CMB in a specific pattern. At GSFC, we are currently working towards two experiments that work in concert to measure this polarization pattern in search of evidence for inflation. The Cosmology Large Angular Scale Surveyor (CLASS) will measure the polarization at frequencies between 40 and 150 GHz from the Atacama Desert in Chile. The Primordial Inflation Polarization Explorer (PIPER) is a balloon-borne experiment that will make similar measurements at frequencies between 200 and 600 GHz.

Practicing What We Preach: Investigating the Role of Social Support in Sport Psychologists’ Well-Being

2015-01-01

Well-being and mental health of psychologists and their clients can be strongly linked to the psychologists’ experience of work. We know from general theories of occupational health psychology that certain work factors will have a greater impact on well-being than others. Work engagement is positively related with occupational health, while burnout and workaholic tendencies relate negatively. An individual’s resources can buffer against these negative effects. Specifically, the environmental resource of social support can impede the impact and instance of workaholism and has a positive influence on burnout. Social support is often encouraged by sport psychologists in protecting an athlete’s well-being. Drawing on theory and research from work and organizational, health and social psychology we explore the lived experiences of burnout and work engagement among applied sport psychologists, investigating their perceptions of how these experiences impact their well-being. Thirty participants from five countries were asked, using semi-structured interviews, to recall specific incidents when feelings of work engagement and burnout occurred. We examined the influence of social support and its impact on these incidents. Thematic analysis revealed that burnout is frequently experienced despite high levels of work engagement. Sources of social support differ between groups of high burnout versus low burnout, as does reference to the dimensions of work engagement. Avenues for future research including investigating the role of mindfulness and therapeutic lifestyle changes for practitioners are outlined. PMID:26696923

Experience as Knowledge in a New Product Development Team: Implications for Knowledge Management

Cooper, Lynne P.

2009-01-01

This study was conducted to better understand how New Product Development (NPD) team members apply their experiences to meet the task needs of their project. Although "experience" is highly valued in team members, little research has looked specifically at experiences as a type of knowledge, and how this knowledge is used in work settings. This research evaluated nearly 200 instances where team members referenced past experiences during team meetings. During these experience exchanges, team members structured the sharing of their experiences to include three common elements: the source of the experience, the nature of the experience, and the degree of relevance to the current work of the team.

This paper describes how team members structured, applied, and integrated their individual experiences and presents the resulting implications for knowledge management systems that wish to exploit experience knowledge.

Purpose In this study, the authors examined the comprehension of sentences with predicates and reflexives that are linked to a nonadjacent noun as a test of the hierarchical ordering deficit (HOD) hypothesis. That hypothesis and more modern versions posit that children with specific language impairment (SLI) have difficulty in establishing nonadjacent (hierarchical) relations among elements of a sentence. The authors also tested whether additional working memory demands in constructions containing reflexives affected the extent to which children with SLI incorrectly structure sentences as indicated by their picture-pointing comprehension responses. Method Sixteen Brazilian Portuguese-speaking children (8;4–l 0;6 [years;months]) with SLI and 16 children with typical language development (TLD) matched for age (±3 months), gender, and socioeconomic status participated in 2 experiments (predicate and reflexive interpretation). In the reflexive experiment, the authors also manipulated working memory demands. Each experiment involved a 4-choice picture selection sentence comprehension task. Results Children with SLI were significantly less accurate on all conditions. Both groups made more hierarchical syntactic construction errors in the long working memory condition than in the short working memory condition. Conclusion The HOD hypothesis was not confirmed. For both groups, syntactic factors (structural assignment) were more vulnerable than lexical factors (prepositions) to working memory effects in sentence miscomprehension. PMID:22232402

Creativity and working memory capacity in sports: working memory capacity is not a limiting factor in creative decision making amongst skilled performers.

Furley, Philip; Memmert, Daniel

2015-01-01

The goal of the study was to investigate the relationship between domain-general working memory capacity and domain-specific creativity amongst experienced soccer players. We administered the automated operation span task in combination with a domain-specific soccer creativity task to a group of 61 experienced soccer players to address the question whether an athlete's domain-specific creativity is restricted by their domain-general cognitive abilities (i.e., working memory capacity). Given that previous studies have either found a positive correlation, a negative correlation, or no correlation between working memory capacity and creativity, we analyzed the data in an exploratory manner by following recent recommendations to report effect-size estimations and their precision in form of 95% confidence intervals. The pattern of results provided evidence that domain-general working memory capacity is not associated with creativity in a soccer-specific creativity task. This pattern of results suggests that future research and theorizing on the role of working memory in everyday creative performance needs to distinguish between different types of creative performance while also taking the role of domain-specific experience into account.

Camos, Valérie; Lagner, Prune; Loaiza, Vanessa M

2017-09-01

Although verbal recall of item and order information is well-researched in short-term memory paradigms, there is relatively little research concerning item and order recall from working memory. The following study examined whether manipulating the opportunity for attentional refreshing and articulatory rehearsal in a complex span task differently affected the recall of item- and order-specific information of the memoranda. Five experiments varied the opportunity for articulatory rehearsal and attentional refreshing in a complex span task, but the type of recall was manipulated between experiments (item and order, order only, and item only recall). The results showed that impairing attentional refreshing and articulatory rehearsal similarly affected recall regardless of whether the scoring procedure (Experiments 1 and 4) or recall requirements (Experiments 2, 3, and 5) reflected item- or order-specific recall. This implies that both mechanisms sustain the maintenance of item and order information, and suggests that the common cumulative functioning of these two mechanisms to maintain items could be at the root of order maintenance.

Saavedra, Javier; López, Marcelino; Gonzáles, Sergio; Cubero, Rosario

2016-09-01

Employment has been highlighted as a determinant of health and as an essential milestone in the recovery process of people with serious mental illness. Different types of programs and public services have been designed to improve the employability of this population. However, there has not been much interest in the meanings attributed to these experiences and the negative aspects of work experience. In this research, we explored the meanings that participants attributed to their work experience and the impact of work on their recovery process. Research participants lived in Andalusia (Spain), a region in southern Europe with a high unemployment rate. Two versions of a semi-structured interview were designed: one for people who were working, and one for unemployed people. Participants' narratives were categorized according to grounded theory and the analyses were validated in group sessions. Apart from several positive effects for recovery, the analysis of the narratives about work experience outlined certain obstacles to recovery. For example, participants mentioned personal conflicts and stress, job insecurity and meaningless jobs. While valid, the idea that employment is beneficial for recovery must be qualified by the personal meanings attributed to these experiences, and the specific cultural and economic factors of each context.

The ability to think strategically is an admired and a sought-after leadership requirement, yet we know little about how it develops. The purpose of this study is to identify specific experiences that contribute to the development of an individual's ability to think strategically. We identified eight work experiences, including different types of organizational projects, processes, and relationships, that contribute to an individual's strategic thinking ability. We also delineate specific characteristics material to each experience. These characteristics indicate that considerable time and focus are required to develop the ability to think strategically. In addition, the experiences are not all accessed equally: Women are less likely to have nonrelational experiences, while chief executive officers are more likely to have the most challenging ones. In addition, we found differences regarding work-related continuing education activities. Respondents rated nonhealthcare conferences and reading behind all other identified experiences that contribute to strategic thinking ability. Individuals can implement several strategies to improve their strategic thinking ability, including deliberately incorporating the requisite experiences into their development plans, ensuring that the experiences incorporate the required characteristics, and improving the benefit received from attending educational programs in nonhealthcare industries. Organizations can implement several strategies to ensure the experiences are as effective as possible, such as appraising gender differences across the experiences and reviewing the organization's strategic planning processes for the characteristics that best encourage strategic thinking.

The two faces of selective memory retrieval: recall specificity of the detrimental but not the beneficial effect.

PubMed

Bäuml, Karl-Heinz T; Dobler, Ina M

2015-01-01

Depending on the degree to which the original study context is accessible, selective memory retrieval can be detrimental or beneficial for the recall of other memories (Bäuml & Samenieh, 2012). Prior work has shown that the detrimental effect of memory retrieval is typically recall specific and does not arise after restudy trials, whereas recall specificity of the beneficial effect has not been examined to date. Addressing the issue, we compared in 2 experiments the effects of retrieval and restudy on recall of other items, when access to the study context was (largely) maintained and when access to the study context was impaired (in Experiment 1 by using the listwise directed-forgetting task, in Experiment 2 by using a prolonged retention interval). In both experiments, selective retrieval but not restudy induced forgetting of other items when context access was maintained, which replicates prior work. In contrast, when context access was impaired, both selective retrieval and restudy induced beneficial effects on other memories. These findings suggest that the detrimental but not the beneficial effect of selective memory retrieval is recall specific. The results are consistent with a recent 2-factor account of selective memory retrieval that attributes the detrimental effect to inhibition or blocking but the beneficial effect to context reactivation processes.

2016-06-01

Studies examining experts' superiority within domain-specific structured pattern recall tasks have typically had athletes perform them at rest, which is far different from how they are executed in their sport. The aim of this study was to investigate whether performing these tasks under different physical exercise intensities influenced pattern recall results of experts, advanced and novices. In two experiments, 68 participants (experiment 1: n = 33; experiment 2: n = 35) were tested using a handball-specific pattern recall task both at rest and during physical exercise. Physical exercises of 60 % heart rate reserve (constant workload: experiment 1) and of 86.5-90 % HRmax (handball-specific interval load: experiment 2) were induced. Results of both experiments revealed significant group differences with experts recalling patterns more accurately than novices but no significant within-subject differences for the two conditions and no interaction between both factors. Our findings replicate prior research concerning perceptual-cognitive expertise in structured specific pattern recall tasks. However, the lack of intergroup differences between the two conditions or interactions was surprising, suggesting sport-specific pattern recall skill is robust to changes in exercise stimuli. Future work is needed to further examine the impact of "physiological specificity" on perceptual-cognitive expertise.

This paper examines how positive psychology principles can be incorporated into clinical training and practice to work with lesbian, gay, bisexual and transgender (LGBT) clients. LGBT psychology literature has all too often relied on heterosexual and cisgender reference groups as the norm with respect to psychological health, primarily framing the experiences of LGBT individuals through the lens of psychopathology. As a result, strengths that could be ascribed to the LGBT experience have been overlooked within training and practice. While positive psychology is actively being incorporated into clinical and counseling psychology curricula, broadening the paradigm to include LGBT individuals has generally not been included in the discussion. Specific recommendations for training psychologists to incorporate and foster positive social institutions, positive subjective experiences and character strengths when working with LGBT clients and celebrating their unique experiences are provided.

Homosexual nursing staff (n = 21) from different parts of Sweden were interviewed about experiences from their psychosocial work environment and about what they consider important points to communicate about lesbians and gay men in nursing. The findings show that most of the informants were partly open about their sexual orientation at work, the women less so than the men. All informants spoke of the fear of being socially excluded. Reported negative experiences included being neglected, harassment, and verbal discomfort based on sexual prejudices. The informants regarded responsibility, the need for knowledge, the consequences of invisibility, and the lesbian's specific situation, important points to communicate regarding homosexuality and nursing.

Dynamic interactions between visual working memory and saccade target selection

PubMed Central

Schneegans, Sebastian; Spencer, John P.; Schöner, Gregor; Hwang, Seongmin; Hollingworth, Andrew

2014-01-01

Recent psychophysical experiments have shown that working memory for visual surface features interacts with saccadic motor planning, even in tasks where the saccade target is unambiguously specified by spatial cues. Specifically, a match between a memorized color and the color of either the designated target or a distractor stimulus influences saccade target selection, saccade amplitudes, and latencies in a systematic fashion. To elucidate these effects, we present a dynamic neural field model in combination with new experimental data. The model captures the neural processes underlying visual perception, working memory, and saccade planning relevant to the psychophysical experiment. It consists of a low-level visual sensory representation that interacts with two separate pathways: a spatial pathway implementing spatial attention and saccade generation, and a surface feature pathway implementing color working memory and feature attention. Due to bidirectional coupling between visual working memory and feature attention in the model, the working memory content can indirectly exert an effect on perceptual processing in the low-level sensory representation. This in turn biases saccadic movement planning in the spatial pathway, allowing the model to quantitatively reproduce the observed interaction effects. The continuous coupling between representations in the model also implies that modulation should be bidirectional, and model simulations provide specific predictions for complementary effects of saccade target selection on visual working memory. These predictions were empirically confirmed in a new experiment: Memory for a sample color was biased toward the color of a task-irrelevant saccade target object, demonstrating the bidirectional coupling between visual working memory and perceptual processing.

Item-specific proactive interference in olfactory working memory.

PubMed

Moss, Andrew; Miles, Christopher; Elsley, Jane; Johnson, Andrew

2018-04-01

We examine item-specific olfactory proactive interference (PI) effects and undertake comparisons with verbal and non-verbal visual stimuli. Using a sequential recent-probes task, we show no evidence for PI with hard-to-name odours (Experiment 1). However, verbalisable odours do exhibit PI effects (Experiment 2). These findings occur despite above chance performance and similar serial position functions across both tasks. Experiments 3 and 4 apply words and faces, respectively, to our modified procedure, and show that methodological differences cannot explain the null finding in Experiment 1. The extent to which odours exhibit analogous PI effects to that of other modalities is, we argue, contingent on the characteristics of the odours employed.

Episodic specificity induction impacts activity in a core brain network during construction of imagined future experiences

PubMed Central

Madore, Kevin P.; Szpunar, Karl K.; Addis, Donna Rose; Schacter, Daniel L.

2016-01-01

Recent behavioral work suggests that an episodic specificity induction—brief training in recollecting the details of a past experience—enhances performance on subsequent tasks that rely on episodic retrieval, including imagining future experiences, solving open-ended problems, and thinking creatively. Despite these far-reaching behavioral effects, nothing is known about the neural processes impacted by an episodic specificity induction. Related neuroimaging work has linked episodic retrieval with a core network of brain regions that supports imagining future experiences. We tested the hypothesis that key structures in this network are influenced by the specificity induction. Participants received the specificity induction or one of two control inductions and then generated future events and semantic object comparisons during fMRI scanning. After receiving the specificity induction compared with the control, participants exhibited significantly more activity in several core network regions during the construction of imagined events over object comparisons, including the left anterior hippocampus, right inferior parietal lobule, right posterior cingulate cortex, and right ventral precuneus. Induction-related differences in the episodic detail of imagined events significantly modulated induction-related differences in the construction of imagined events in the left anterior hippocampus and right inferior parietal lobule. Resting-state functional connectivity analyses with hippocampal and inferior parietal lobule seed regions and the rest of the brain also revealed significantly stronger core network coupling following the specificity induction compared with the control. These findings provide evidence that an episodic specificity induction selectively targets episodic processes that are commonly linked to key core network regions, including the hippocampus.

2016-04-01

We investigated the relationship between workplace supervisory social interactions and blood pressure outcomes using hourly diary entries and ambulatory blood pressure data from an experience sampling study of 55 long-term care employees. After accounting for relevant cardiovascular controls, significant effects of supervisory interactions on cardiovascular reactivity and recovery were found. Multilevel analyses revealed that negatively perceived supervisory interactions predicted higher systolic blood pressure at work (B = -1.59, p < .05, N observations = 422). Using time-lagged hierarchical regression analyses, the average perceived valence of supervisory interactions at work predicted average systolic blood pressure recovery after work (B = -14.52, p < .05, N = 33). Specifically, negatively perceived supervisory interactions at work predicted poorer cardiovascular recovery after work. Suggestions for improving practices in organizations and in experience sampling research are discussed. (c) 2016 APA, all rights reserved).

Support from the workplace seems to be a key element in addressing the poor return-to-work (RTW) rate of employees with breast cancer. We aim to acquire an in-depth understanding of how Flemish employees experience their RTW after breast cancer and the support from the workplace. Fourteen in-depth interviews of women who experienced breast cancer and returned to work (high school graduates, age range 42-55 years, mean age 48 at time of surgery) were analysed using the Qualitative Analysis Guide of Leuven (QUAGOL), based on a Grounded Theory approach. The key experiences were feeling vulnerable, feeling able to work and need for support. Although little diversity in RTW experiences was found, the background of the vulnerability varied. Women experienced support (which could be emotional or practical) only as adequate if it addressed their specific vulnerability. Employees felt particularly vulnerable. Vulnerability is not the same as low-work ability and as such it should be added as theoretical concept in RTW research. Adequate workplace support addresses the specific vulnerability of an individual woman. Our study offers a nuanced insight into the RTW process of breast cancer survivors. Upon actual return-to-work (RTW) after breast cancer treatment, women feel vulnerable but able to work and, hence, have a high need for workplace support. Support from the workplace during RTW after breast cancer treatment is experienced as adequate when it expresses genuine recognition of the individual woman's vulnerability.

Why some colors appear more memorable than others: A model combining categories and particulars in color working memory.

PubMed

Bae, Gi-Yeul; Olkkonen, Maria; Allred, Sarah R; Flombaum, Jonathan I

2015-08-01

Categorization with basic color terms is an intuitive and universal aspect of color perception. Yet research on visual working memory capacity has largely assumed that only continuous estimates within color space are relevant to memory. As a result, the influence of color categories on working memory remains unknown. We propose a dual content model of color representation in which color matches to objects that are either present (perception) or absent (memory) integrate category representations along with estimates of specific values on a continuous scale ("particulars"). We develop and test the model through 4 experiments. In a first experiment pair, participants reproduce a color target, both with and without a delay, using a recently influential estimation paradigm. In a second experiment pair, we use standard methods in color perception to identify boundary and focal colors in the stimulus set. The main results are that responses drawn from working memory are significantly biased away from category boundaries and toward category centers. Importantly, the same pattern of results is present without a memory delay. The proposed dual content model parsimoniously explains these results, and it should replace prevailing single content models in studies of visual working memory. More broadly, the model and the results demonstrate how the main consequence of visual working memory maintenance is the amplification of category related biases and stimulus-specific variability that originate in perception.

Visuospatial and verbal memory in mental arithmetic.

PubMed

Clearman, Jack; Klinger, Vojtěch; Szűcs, Dénes

2017-09-01

Working memory allows complex information to be remembered and manipulated over short periods of time. Correlations between working memory and mathematics achievement have been shown across the lifespan. However, only a few studies have examined the potentially distinct contributions of domain-specific visuospatial and verbal working memory resources in mental arithmetic computation. Here we aimed to fill this gap in a series of six experiments pairing addition and subtraction tasks with verbal and visuospatial working memory and interference tasks. In general, we found higher levels of interference between mental arithmetic and visuospatial working memory tasks than between mental arithmetic and verbal working memory tasks. Additionally, we found that interference that matched the working memory domain of the task (e.g., verbal task with verbal interference) lowered working memory performance more than mismatched interference (verbal task with visuospatial interference). Findings suggest that mental arithmetic relies on domain-specific working memory resources.

Internationally trained health professionals are an important part of the domestic workforce, but little is known about the working experiences of internationally trained pharmacists (ITPs) in Great Britain (GB). The purpose of this study is to explore the work experiences of ITPs practising in the community or hospital sector in GB. Twenty-five semi-structured, face-to-face interviews were conducted with a sample of European Economic Area (EEA) and non-EEA pharmacists who, at the time of the study, practised in the community (n = 20) or hospital sector (n = 5) in the North West England from March to May 2009. In general, ITPs complained about their heavy workload, long working hours and lack of support from their employers. Specifically, EEA pharmacists in most cases felt excluded from the professional network and sensed colleagues saw them as 'foreigners' while some non-EEA pharmacists had to deal with a level of hostility from patients. This novel research provides a foundation for future work on ITPs in GB and could assist employers to better target their efforts in development of standards to support the working experiences of ITPs in GB. © 2014 Royal Pharmaceutical Society.

South African student nurses experience emotional discomfort that might influence their adjustment and coping while working with mentally challenged individuals. Adjustment and coping might impact on their mental health and support needed while working in this challenging context. Student nurses working with mentally challenged individuals experience emotional discomfort that may result in work-related stress. The experiences of student nurses working with mentally challenged individuals were explored and described as it may influence their adjustment, coping and result in work-related stress, impacting on their mental health. The study used a qualitative, explorative, descriptive, contextual research design with a case study as strategy. Thirteen student nurses from a specific higher educational institution in Gauteng, South Africa, participated in the focus group interviews. The researcher utilized reflective journals, a reflective letter, naïve sketches, drawings and field notes to collect data. Data analysis was done according to Tesch's descriptive method of open coding and theme analysis. A central storyline emerged where student nurses described working with mentally challenged individuals as a process of personal transformation that was initiated by an engagement on a deeper emotional level with these individuals. The process of personal transformation started a journey towards the discovery of meaning for the self, as student nurses. Student nurses working in challenging environments during their training may experience emotional discomfort and need additional support in coping and adjustment within this context. The nurse educator plays an important role in providing this support to manage work-related stress as well as in creating learning opportunities for the student nurses working in challenging contexts. © 2012 Blackwell Publishing.

An Internship May Not Be Enough: Enhancing Bioscience Industry Job Readiness through Practicum Experiences.

PubMed

Cramer, Jason M; Hamilton, Paul T

2017-04-01

In contrast to the narrowing of options in academic careers, the bioscience industry offers robust employment opportunities for STEM-trained workers, especially those who display both scientific and business talent. Unfortunately, traditional science programs typically lack curricular features that develop this type of worker. The North Carolina State University Master of Microbial Biotechnology (MMB) program facilitates industry-specific experiential learning to fill this training gap. Similar programs often rely on a single industry internship to provide students relevant work experience, but completion of one internship might not suffice to position students for employment in a highly competitive job market. The MMB program requires students to complete an internship and three practicum projects in an industry setting, to promote development of key skills in a variety of areas, to build confidence in the ability to perform initial job duties, and to establish a more extensive work history in industry. In this Perspective we discuss an unmet need in undergraduate and graduate STEM education that can be filled by incorporating a similar set of industry-specific work experiences for students who desire to transition from academe into the life science industry.

Hip Hop Dance Experience Linked to Sociocognitive Ability.

PubMed

Bonny, Justin W; Lindberg, Jenna C; Pacampara, Marc C

2017-01-01

Expertise within gaming (e.g., chess, video games) and kinesthetic (e.g., sports, classical dance) activities has been found to be linked with specific cognitive skills. Some of these skills, working memory, mental rotation, problem solving, are linked to higher performance in science, technology, math, and engineering (STEM) disciplines. In the present study, we examined whether experience in a different activity, hip hop dance, is also linked to cognitive abilities connected with STEM skills as well as social cognition ability. Dancers who varied in hip hop and other dance style experience were presented with a set of computerized tasks that assessed working memory capacity, mental rotation speed, problem solving efficiency, and theory of mind. We found that, when controlling for demographic factors and other dance style experience, those with greater hip hop dance experience were faster at mentally rotating images of hands at greater angle disparities and there was a trend for greater accuracy at identifying positive emotions displayed by cropped images of human faces. We suggest that hip hop dance, similar to other more technical activities such as video gameplay, tap some specific cognitive abilities that underlie STEM skills. Furthermore, we suggest that hip hop dance experience can be used to reach populations who may not otherwise be interested in other kinesthetic or gaming activities and potentially enhance select sociocognitive skills.

Masculinities fathering and health: the experiences of African-Caribbean and white working class fathers.

PubMed

Williams, Robert Alan

2007-01-01

There is a developing body of research that investigates the links between masculinities and men's health experiences, but the links between masculinities and the health of fathers has been a neglected focus for research in the UK. This paper presents some of the findings drawn from a parent study which investigated African-Caribbean and white working class fathers' experiences of fathering, health and social connectedness. Data are drawn from interviews with 13 men (6 African-Caribbean and 7 White working class) living in a city in the West Midlands area of the UK. In this paper, I analyse and discuss African-Caribbean and white working class fathers' stories about the meaning of health, the influences upon their health, and their health practices. It was found that for the African-Caribbean fathers specifically, anticipated or perceived racist prejudice, abuse or discrimination influenced their health experiences. However, the meaning of health for both ethnic groups of fathers was as functional capacity, that is health was an asset that allowed fathers to meet the obligations of paid work and fathering. These obligations were also associated with a restricted sense of personal agency for the men interviewed, and the associated constraints were linked to transgressive consumption of alcohol, food and tobacco. In addition, fathers were also involved in solitary ways of dealing with their vulnerability, vulnerability that was associated with fathers' health concerns, and other difficult life experiences. Fathers' solitary experiences of vulnerability were also mediated by hegemonic forms of masculinity. Nevertheless, the experience of fathering within the lifecourse influenced men's health experiences: reflexivity and challenges to both transgressive consumption and solitary experiences were linked to fathers' perceived obligations to children. The significance of gender, ethnicity and social class for theory and future research with working class fathers and boys is identified, and the need for gender-sensitive public health and health promotion interventions regarding the 'work-family balance' and working class fathers' personal and social skills is also discussed.

Cerebellar contribution to spatial event processing: involvement in procedural and working memory components.

Spatial function is one of the cognitive functions altered in the presence of cerebellar lesions. We investigated the cerebellar contribution to the acquisition of spatial procedural and working memory components by means of a radial maze. To establish whether a cerebellar lesion would cause a deficit in solving the radial maze, a first experiment was carried out by using a full-baited maze procedure in different experimental groups, with or without cerebellar lesion and with or without pretraining. Non-pretrained hemicerebellectomized (HCbed) animals exhibited impaired performances in all (motor, spatial and procedural) task aspects. Pre-trained HCbed animals performed similarly to control animals in the task aspects linked to the processing of spatial and procedural factors. To distinguish procedural from working memory components, a forced-choice paradigm of the radial maze was used in the second experiment. Non-pretrained HCbed rats continued to make a lot of errors and show severe perseverative tendencies, already observed in the first experiment, supporting a specific cerebellar role in acquiring new behaviours and in modifying them in relation to the context. Interestingly, hindered from putting the acquired explorative patterns into action and compelled to use only working memory abilities, the pretrained HCbed group exhibited a dramatic worsening of performance. In conclusion, the present findings demonstrate that cerebellar damage induces a specific behaviour in radial maze tasks, characterized by an inflexible use of the procedures (if indeed any procedure was acquired before the lesion) and by a severe impairment in working memory processes.

Watson, J. Kevin

1989-01-01

The In-Space Technology Experiments Program (INSTEP) provides an opportunity to explore the many critical questions which can only be answered by experimentation in space. The objective of the Extravehicular Activity Welding Experiment definition project was to define the requirements for a spaceflight experiment to evaluate the feasibility of performing manual welding tasks during EVA. Consideration was given to experiment design, work station design, welding hardware design, payload integration requirements, and human factors (including safety). The results of this effort are presented. Included are the specific objectives of the flight test, details of the tasks which will generate the required data, and a description of the equipment which will be needed to support the tasks. Work station requirements are addressed as are human factors, STS integration procedures and, most importantly, safety considerations. A preliminary estimate of the cost and the schedule for completion of the experiment through flight and postflight analysis are given.

What Is Your Faction? Multidimensional Evidence for the Divergent Series As the Basis for a New Model of Personality and Work Life.

de Souza, Bruno C; Roazzi, Antonio

2017-01-01

Introduction: The successful "Divergent" sci-fi trilogy by writer Veronica Roth portrays a dystopian and post-apocalyptic society where the population is divided into five groups called "Factions," each with a specific social role and associated to a specific set of psychological traits. Though fictional, such typology is compelling and may provide a significant contribution to personality studies. Objectives: To investigate the accuracy of the classification of psychological and sociocultural traits into five Factions as described in Divergent and their potential practical usefulness for understanding work life choices and experiences in organizations. Method: A total of 217 Brazilian adult men and women of various ages, socioeconomic status and ethnicities were submitted to measures of several psychological and sociocultural variables, as well as of how strongly they supposedly manifest each Faction. The resulting dataset was studied using Smallest Space Analysis (SSA) and Facet Theory. Results: The Factions were shown not only to be associated to psychological variables in ways consistent with the descriptions from Divergent, but also to be related to specific aspects of one's work life in organizations. Conclusion: The five Factions conceived by Roth appear to constitute an original set of constructs that are psychologically valid and, at the same time, of practical use in predicting work life choices and experiences. This justifies engaging in future empirical and theoretical work toward a new scientific model of potential practical value.

Happiness increases verbal and spatial working memory capacity where sadness does not: Emotion, working memory and executive control.

PubMed

Storbeck, Justin; Maswood, Raeya

2016-08-01

The effects of emotion on working memory and executive control are often studied in isolation. Positive mood enhances verbal and impairs spatial working memory, whereas negative mood enhances spatial and impairs verbal working memory. Moreover, positive mood enhances executive control, whereas negative mood has little influence. We examined how emotion influences verbal and spatial working memory capacity, which requires executive control to coordinate between holding information in working memory and completing a secondary task. We predicted that positive mood would improve both verbal and spatial working memory capacity because of its influence on executive control. Positive, negative and neutral moods were induced followed by completing a verbal (Experiment 1) or spatial (Experiment 2) working memory operation span task to assess working memory capacity. Positive mood enhanced working memory capacity irrespective of the working memory domain, whereas negative mood had no influence on performance. Thus, positive mood was more successful holding information in working memory while processing task-irrelevant information, suggesting that the influence mood has on executive control supersedes the independent effects mood has on domain-specific working memory.

To correlate workgroup engagement in nursing teams and the clinical learning experience of nursing students. Work engagement plays a pivotal role in explaining motivational dynamics. Nursing education is workplace-based and, through their clinical placements, nursing students develop both their clinical competences and their professional identity. However, there is currently a lack of evidence on the role of work engagement related to students' learning experiences. A total of 519 nurses and 519 nursing students were enrolled in hospital settings. The Utrecht Work Engagement Scale (UWES) was used to assess work engagement, and the Clinical Learning Environment and Supervision plus nurse Teacher (CLES+T) scale was used to assess students' learning experience. A multilevel linear regression analysis was performed. Group-level work engagement of nurses correlated with students' clinical learning experience (β = 0.11, P < 0.001). Specifically, the 'absorption' and 'dedication' factors mostly contributed to enhancing clinical learning (respectively, β = 0.37, P < 0.001 and β = 0.20, P < 0.001). Nursing teams' work engagement is an important motivational factor to enhance effective nursing education. Nursing education institutions and health-care settings need to conjointly work to build effective organisational climates. The results highlighted the importance of considering the group-level analysis to understand the most effective strategies of intervention for both organisations and nursing education. © 2015 John Wiley & Sons Ltd.

to explore high-dependency care nurses' experiences of their psychosocial work environment. four focus groups were conducted with 23 emergency and critical care hospital nurses in Brunei. All sessions were recorded, transcribed verbatim and analysed using inductive-approach thematic analysis. three major themes were identified. 'Specialisation/specific skills' explained a fundamental requirement for the high-dependency care nurses to work effectively and efficiently in their workplace. 'Task completion' narrated the pressure they experienced to complete their tasks within time constraints exacerbated by a reduced number of staff. 'Acknowledgement' signified their need for fair and adequate reward for their hard work through career progression and promotion. this study facilitates the design of future interventions and policies that promote a healthy psychosocial work environment by ensuring nurses working in these areas have the required specialisation skills, there is a balance of workload and nurse-to-patient ratios, and they are offered fairness and equity in career progression and promotion.

Methodological considerations in the use of audio diaries in work psychology: Adding to the qualitative toolkit.

Crozier, Sarah E; Cassell, Catherine M

2016-06-01

The use of longitudinal methodology as a means of capturing the intricacies in complex organizational phenomena is well documented, and many different research strategies for longitudinal designs have been put forward from both a qualitative and quantitative stance. This study explores a specific emergent qualitative methodology, audio diaries, and assesses their utility for work psychology research drawing on the findings from a four-stage study addressing transient working patterns and stress in UK temporary workers. Specifically, we explore some important methodological, analytical and technical issues for practitioners and researchers who seek to use these methods and explain how this type of methodology has much to offer when studying stress and affective experiences at work. We provide support for the need to implement pluralistic and complementary methodological approaches in unearthing the depth in sense-making and assert their capacity to further illuminate the process orientation of stress. This study illustrates the importance of verbalization in documenting stress and affective experience as a mechanism for accessing cognitive processes in making sense of such experience.This study compares audio diaries with more traditional qualitative methods to assess applicability to different research contexts.This study provides practical guidance and a methodological framework for the design of audio diary research and design, taking into account challenges and solutions for researchers and practitioners.

Rise and fall of competitiveness in individualistic and collectivistic societies.

Leibbrandt, Andreas; Gneezy, Uri; List, John A

2013-06-04

Competitiveness pervades life: plants compete for sunlight and water, animals for territory and food, and humans for mates and income. Herein we investigate human competitiveness with a natural experiment and a set of behavioral experiments. We compare competitiveness in traditional fishing societies where local natural forces determine whether fishermen work in isolation or in collectives. We find sharp evidence that fishermen from individualistic societies are far more competitive than fishermen from collectivistic societies, and that this difference emerges with work experience. These findings suggest that humans can evolve traits to specific needs, support the idea that socio-ecological factors play a decisive role for individual competitiveness, and provide evidence how individualistic and collectivistic societies shape economic behavior.

The author examined human-resource professionals' occupation-related and general work experience, socialization from participation in professional activities, organizational size, and perceived independence as predictors of perceptions of organizational politics (POPS). Results varied with the author's use of the overall POPS scale (K. M. Kacmar & G. R. Ferris, 1991) vs. a more specific subscale that measured perceptions related to such issues as pay- and promotion-related politics. It was most notable that work experience appeared to have an inverse relationship with POPS among human-resource professionals in the area of pay and promotions. The author discussed results in relation to the implications and directions for future research.

Resuming normal activities, such as work and school, is an important dimension of psychosocial recovery in cancer survivorship. Minimal data exist regarding adolescents or young adults' experiences of returning to school or work after cancer. The purpose of this study was to explore the processes of resuming work and school among adolescents and young adults after hematopoietic cell transplantation (HCT). In-depth interviews were conducted with 18 adolescents and young adults, who were 15-29 years when they underwent HCT and 6-60 months post-transplant at study enrollment. Interview transcripts were systematically analyzed using Grounded Theory methodology. Participants described the context in which they attempted to return to work or school, specific challenges they faced, and strategies they developed in these environments. Feeling left behind from their peers and their pre-diagnosis selves, participants described "rushing" back to school and work impulsively, taking on too much too quickly while facing overwhelming physical and cognitive demands. Factors motivating this sense of urgency as well as barriers to successful and sustainable reentry in these settings are also addressed. Findings are discussed in the context of important opportunities for clinical management, age-appropriate interventions, and implications for future research. A better understanding of psychosocial late effects, specifically related to school and work trajectories after cancer, is critical to survivorship care for adolescent and young adult cancer survivors.

2017-10-13

We introduce our efforts within the project 'The science of deep specification' to work out the key formal underpinnings of industrial-scale formal specifications of software and hardware components, anticipating a world where large verified systems are routinely built out of smaller verified components that are also used by many other projects. We identify an important class of specification that has already been used in a few experiments that connect strong component-correctness theorems across the work of different teams. To help popularize the unique advantages of that style, we dub it deep specification , and we say that it encompasses specifications that are rich , two-sided , formal and live (terms that we define in the article). Our core team is developing a proof-of-concept system (based on the Coq proof assistant) whose specification and verification work is divided across largely decoupled subteams at our four institutions, encompassing hardware microarchitecture, compilers, operating systems and applications, along with cross-cutting principles and tools for effective specification. We also aim to catalyse interest in the approach, not just by basic researchers but also by users in industry.This article is part of the themed issue 'Verified trustworthy software systems'. © 2017 The Author(s).

The purpose of this study was to evaluate a model for considering general and specific elements of student experience in a gateway course in undergraduate Financial Accounting in a large university on the East Coast, USA. Specifically, the study evaluated a bifactor analytic strategy including a general factor of student classroom experience, conceptualized as student engagement as rooted in flow theory, as well as factors representing specific dimensions of experience. The study further evaluated the association between these general and specific factors and both student classroom practices and educational outcomes. The sample of students (N = 407) in two cohorts of the undergraduate financial accounting course participated in the Experience Sampling Method (ESM) measuring students' classroom practices, perceptions, engagement, and perceived learning throughout the one-semester course. Course grade information was also collected. Results showed that a two-level bifactor model fit the data better than two traditional (i.e., non-bifactor) models and also avoided significant multicollinearity of the traditional models. In addition to student engagement (general factor), specific dimensions of classroom experience in the bifactor model at the within-student level included intrinsic motivation, academic intensity, salience, and classroom self-esteem. At the between-student level, specific aspects included work orientation, learning orientation, classroom self-esteem, and disengagement. Multilevel Structural Equation Modeling (MSEM) demonstrated that sitting in the front of the classroom (compared to the sitting in the back), taking notes, active listening, and working on problems during class had a positive effect on within-student variation in student engagement and attention. Engagement, in turn, predicted perceived learning. With respect to between-student effects, the tendency to sit in front seats had a significant effect on student engagement, which in turn had a significant effect on perceived learning and course grades. A significant indirect relationship of seating and active learning strategies on learning and course grade as mediated by student engagement was found. Support for the general aspect of student classroom experience was interpreted with flow theory and suggested the need for additional research. Findings also suggested that active learning strategies are associated with positive learning outcomes even in educational environments where possibilities for action are relatively constrained.

Multilevel Structural Equation Modeling (MSEM) demonstrated that sitting in the front of the classroom (compared to the sitting in the back), taking notes, active listening, and working on problems during class had a positive effect on within-student variation in student engagement and attention. Engagement, in turn, predicted perceived learning. With respect to between-student effects, the tendency to sit in front seats had a significant effect on student engagement, which in turn had a significant effect on perceived learning and course grades. A significant indirect relationship of seating and active learning strategies on learning and course grade as mediated by student engagement was found. Support for the general aspect of student classroom experience was interpreted with flow theory and suggested the need for additional research. Findings also suggested that active learning strategies are associated with positive learning outcomes even in educational environments where possibilities for action are relatively constrained.

Barriers to physical activity among working mothers.

Dombrowski, Jill J

2011-04-01

Working mothers experience several barriers to physical activity. If these barriers can be identified by occupational health nurses and they can partner with working mothers to reduce these perceived barriers, the health of these workers can be improved and chronic disease risk prevented. The purpose of this study was to measure the effect of self-regulatory efficacy on physical activity among working mothers and to describe specific barriers to physical activity. The Barriers Specific Self-Efficacy Scale (BARSE) and the Kaiser Physical Activity Survey (KPAS) were used to measure the variables. Self-regulatory efficacy was found to be a strong predictor of physical activity in a diverse sample of working mothers who did not meet current recommendations for physical activity. Occupational health nurses can use these findings to design programs for groups and for counseling individuals. Copyright 2011, SLACK Incorporated.

Motivational Implications of Pain: Chronicity, Psychological Distress, and Work Goal Construal in a National Sample of Adults

Karoly, Paul; Ruehlman, Linda S.

2005-01-01

A heterogeneous national sample of adults (mean age = 40 years) employed in management positions was contacted by random digit dialing procedures and interviewed about current pain experience, work-goal cognitions, and psychological status (depression and anxiety). In accord with predictions, persistent pain experience was differentially related to the construal of work-related goals. Specifically, individuals with both persistent and episodic pain (relative to those with no pain) reported lower levels of goal-centered value, self-efficacy, and positive arousal and heightened perceptions of goal-based self-criticism, negative arousal, and conflict between work and nonwork goals. Furthermore, regression analyses revealed that goal cognition accounted for unique variance in depression and anxiety over and above the contribution of pain chronicity. PMID:8891717

Compromised careers: the occupational transition of immigration and resettlement.

PubMed

Suto, Melinda

2009-01-01

Work is a significant occupational transition that occurs with immigration and resettlement. Problems finding work and regaining economic capital are multi-factorial, differentiated by gender and mediated by specific contexts. Surprisingly, past education and work experience are unreliable predictors of successful employment outcomes. Critical theory and ethnographic concepts informed the methodological approach. Data were generated primarily through in-depth interviews, conducted in English, with 14 well-educated women who immigrated to Canada as adults and sought employment in their professions. The thematic findings were analyzed using Bourdieu's [7] concepts of capital, field and habitus. The theme Compromised Careers describes the downward occupational (work) mobility that occurs despite expectations that education, credentials and work experience are transferable to desirable employment. A devaluation of foreign qualifications and no relevant Canadian work experience function with gendered responsibilities, less social support, and time spent in resettlement activities to create negative work trajectories. The role that federal policies and professional organizations play is examined to reveal the tension between individuals' efforts to find employment and institutional barriers that impede these actions. A critical inquiry approach examined the ruling relations to show how power and privilege function in relation to migrants' occupational transitions.

Evaluation of the impact of resident work hour restrictions on resident outpatient clinical experience.

To estimate the effect of work hour restrictions on resident outpatient clinical experience. Schedule templates from academic years 1998-1999 (before work hour restrictions), 2002-2003 (when night float rotation was added in anticipation of work hour restrictions), and 2008-2009 (during work hour restrictions) were compared for outpatient clinic experience before and after work hour restrictions were implemented. Actual clinics on specific rotations and estimated patient encounters per scheduled clinic were considered. Between academic year (AY) 1998-1999 and AY 2008-2009 there was a generalized downward trend in average outpatient encounters for postgraduate year (PGY)-2, PGY-3 and PGY-4 residents (45%, 34% and 36%, respectively). For obstetrics, gynecology and ambulatory rotations, there was a downward trend in average outpatient encounters for each rotation type (61%, 14% and 63%, respectively). The average number of scheduled clinics per week was slightly decreased when comparing AY 1998-1999 to either AY 2002-2003 or AY 2008-2009. Rotation schedules before and after work hour restrictions demonstrated a downward trend in the number of scheduled outpatient encounters. These findings indicate a potential negative impact on preparation for clinical practice.

Group work as an incentive for learning – students’ experiences of group work

PubMed Central

Hammar Chiriac, Eva

2014-01-01

Group work is used as a means for learning at all levels in educational systems. There is strong scientific support for the benefits of having students learning and working in groups. Nevertheless, studies about what occurs in groups during group work and which factors actually influence the students’ ability to learn is still lacking. Similarly, the question of why some group work is successful and other group work results in the opposite is still unsolved. The aim of this article is to add to the current level of knowledge and understandings regarding the essence behind successful group work in higher education. This research is focused on the students’ experiences of group work and learning in groups, which is an almost non-existing aspect of research on group work prior to the beginning of the 21st century. A primary aim is to give university students a voice in the matter by elucidating the students’ positive and negative points of view and how the students assess learning when working in groups. Furthermore, the students’ explanations of why some group work ends up being a positive experience resulting in successful learning, while in other cases, the result is the reverse, are of interest. Data were collected through a study-specific questionnaire, with multiple choice and open-ended questions. The questionnaires were distributed to students in different study programs at two universities in Sweden. The present result is based on a reanalysis and qualitative analysis formed a key part of the study. The results indicate that most of the students’ experiences involved group work that facilitated learning, especially in the area of academic knowledge. Three important prerequisites (learning, study-social function, and organization) for group work that served as an effective pedagogy and as an incentive for learning were identified and discussed. All three abstractions facilitate or hamper students’ learning, as well as impact their experiences with group work. PMID:24926282

Nurses and the sterilization experiments of Auschwitz: a postmodernist perspective.

PubMed

Benedict, Susan; Georges, Jane M

2006-12-01

The medical experiments conducted on non-consenting prisoners of Nazi concentration camps during World War II necessitated the codification of principles to protect human subjects of research. Auschwitz was the largest and one of the most infamous of the camps and the site of numerous 'medical' experiments. This historical study uses primary source documents obtained from archives in England and Germany to describe one type of experiment carried out at Auschwitz - the sterilization experiments. The purpose of these experiments was to perfect a technique in which non-Aryans could be prevented from reproducing while still being able to work as slave laborers. These narratives regarding the sterilization experiments at Auschwitz are remarkable in that they contain previously undocumented information regarding the voluntary and involuntary involvement of nurses. Following these narratives, a discussion of ethics in relation to the Holocaust is presented with a specific focus on the work of Agamben. Implications of the Auschwitz narratives for the application of codes of ethical principles and contemporary nursing are discussed from a postmodernist perspective.

Hip Hop Dance Experience Linked to Sociocognitive Ability

Bonny, Justin W.; Lindberg, Jenna C.; Pacampara, Marc C.

2017-01-01

Expertise within gaming (e.g., chess, video games) and kinesthetic (e.g., sports, classical dance) activities has been found to be linked with specific cognitive skills. Some of these skills, working memory, mental rotation, problem solving, are linked to higher performance in science, technology, math, and engineering (STEM) disciplines. In the present study, we examined whether experience in a different activity, hip hop dance, is also linked to cognitive abilities connected with STEM skills as well as social cognition ability. Dancers who varied in hip hop and other dance style experience were presented with a set of computerized tasks that assessed working memory capacity, mental rotation speed, problem solving efficiency, and theory of mind. We found that, when controlling for demographic factors and other dance style experience, those with greater hip hop dance experience were faster at mentally rotating images of hands at greater angle disparities and there was a trend for greater accuracy at identifying positive emotions displayed by cropped images of human faces. We suggest that hip hop dance, similar to other more technical activities such as video gameplay, tap some specific cognitive abilities that underlie STEM skills. Furthermore, we suggest that hip hop dance experience can be used to reach populations who may not otherwise be interested in other kinesthetic or gaming activities and potentially enhance select sociocognitive skills.

2018-02-01

The purpose of the current review paper is to identify and describe challenges to work-life integration in neuropsychology, and from this review extrapolate an initial set of recommendations and present a set of scenarios in which the recommendations might apply in the hopes of improving quality of life for current and prospective neuropsychologists. Specific areas of focus include diversity, early and mid-career transitions, and potential barriers to advancement in specific practice settings. A broad review was conducted of extant literature on work-life integration. There is scant scientific literature in this area that is specific to neuropsychologists, or even psychology as a whole. Subsequently, the majority of this review was collected from more developed literatures in business and medical fields. The authors then provided recommendations based on experiences in their respective careers. Attempts were made to promote generalizability of recommendations for neuropsychologists in different settings. Evidence supports a potentially adverse impact on quality of life and overall life satisfaction when work and personal lives conflict. This manuscript identifies some of the potential risks when work and life responsibilities are not well integrated. It is anticipated this will serve as a catalyst for future studies on work-life integration in the field of neuropsychology, specifically.

Mind wandering and reading comprehension: examining the roles of working memory capacity, interest, motivation, and topic experience.

PubMed

Unsworth, Nash; McMillan, Brittany D

2013-05-01

Individual differences in mind wandering and reading comprehension were examined in the current study. In particular, individual differences in mind wandering, working memory capacity, interest in the current topic, motivation to do well on the task, and topic experience and their relations with reading comprehension were examined in the current study. Using confirmatory factor analysis and structural equation modeling it was found that variation in mind wandering while reading was influenced by working memory capacity, topic interest, and motivation. Furthermore, these same factors, along with topic experience, influenced individual differences in reading comprehension. Importantly, several factors had direct effects on reading comprehension (and mind wandering), while the relation between reading comprehension (and mind wandering) and other factors occurred via indirect effects. These results suggest that both domain-general and domain-specific factors contribute to mind wandering while reading and to reading comprehension.

Developing standard operating procedures for gene drive research in disease vector mosquitoes.

Numerous arthropod species represent potential targets for gene-drive-based population suppression or replacement, including those that transmit diseases, damage crops, or act as deleterious invasive species. Containment measures for gene drive research in arthropods have been discussed in the literature, but the importance of developing safe and effective standard operating procedures (SOPs) for these types of experiments has not been adequately addressed. Concisely written SOPs link safe work practices, containment measures, institutional training, and research-specific protocols. Here we discuss information to be considered by principal investigators, biosafety officers, and institutional biosafety committees as they work together to develop SOPs for experiments involving gene drive in arthropods, and describe various courses of action that can be used to maintain the effectiveness of SOPs through evaluation and revision. The information provided herein will be especially useful to investigators and regulatory personnel who may lack extensive experience working with arthropods under containment conditions.

Trainees and clinicians from high-income countries are increasingly engaging in global health (GH) efforts, particularly in resource-limited settings. Concomitantly, there is a growing demand for these individuals to be better prepared for the common challenges and controversies inherent in GH work. This is a state-of-the-art review article in which we outline what is known about the current scope of trainee and clinician involvement in GH experiences, highlight specific considerations and issues pertinent to GH engagement, and summarize preparation recommendations that have emerged from the literature. The article is focused primarily on short-term GH experiences, although much of the content is also pertinent to long-term work. Suggestions are made for the health care community to develop and implement widely endorsed preparation standards for trainees, clinicians, and organizations engaging in GH experiences and partnerships.

Coming Out in Class: Challenges and Benefits of Active Learning in a Biology Classroom for LGBTQIA Students

PubMed Central

Cooper, Katelyn M.; Brownell, Sara E.

2016-01-01

As we transition our undergraduate biology classrooms from traditional lectures to active learning, the dynamics among students become more important. These dynamics can be influenced by student social identities. One social identity that has been unexamined in the context of undergraduate biology is the spectrum of lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) identities. In this exploratory interview study, we probed the experiences and perceptions of seven students who identify as part of the LGBTQIA community. We found that students do not always experience the undergraduate biology classroom to be a welcoming or accepting place for their identities. In contrast to traditional lectures, active-learning classes increase the relevance of their LGBTQIA identities due to the increased interactions among students during group work. Finally, working with other students in active-learning classrooms can present challenges and opportunities for students considering their LGBTQIA identity. These findings indicate that these students’ LGBTQIA identities are affecting their experience in the classroom and that there may be specific instructional practices that can mitigate some of the possible obstacles. We hope that this work can stimulate discussions about how to broadly make our active-learning biology classes more inclusive of this specific population of students. PMID:27543636

This article describes an innovative initiative to support partnership working between trade unions and management in three National Health Service Trusts, by means of shared participation in a series of learning and development days. Although there is existing evidence, within the literature on partnership, of the benefits of partnership working for employees and employers, there is little discussion of processes by which effective partnership is developed. More specifically, there is no current academic literature on the role of education in enabling improved partnership working between trade unions and managers. The findings of the evaluation suggest that the pilot provided a successful learning experience as well as a number of pointers for improving future developments of this nature. The recommendations include embedding of partnership work within existing staff development processes. Copyright © 2011 Elsevier Ltd. All rights reserved.

Velichkovsky, B M; Challis, B H; Pomplun, M

1995-01-01

Empirical and theoretical evidence for the concept of working memory is considered. We argue that the major weakness of this concept is its loose connection with the knowledge about background perceptive and cognitive processes. Results of two relevant experiments are provided. The first study demonstrated the classical chunking effect in a speeded visual search and comparison task, the proper domain of a large-capacity very short term sensory store. Our second study was a kind of extended levels-of-processing experiment. We attempted to manipulate visual, phonological, and (different) executive components of long-term memory in the hope of finding some systematic relationships between these forms of processing. Indeed, the results demonstrated a high degree of systematicity without any apparent need for a concept such as working memory for the explanation. Accordingly, the place for working memory is at all the interfaces where our metacognitive strategies interfere with mostly domain-specific cognitive mechanisms. Working memory is simply our work with memory.

Clinician Experiences Assessing Work Disability Related to Mental Disorders

2015-01-01

Objective Medical certification is one of the basic administrative mechanisms used by social policies aimed at income protection. The assessment of work disability is central to the income protection application. Yet, there is evidence suggesting that determining work disability related to mental disorders is challenging. Although essential to the disability application process, few studies have looked at physician and other clinician experiences with the process. However, this type of information is critical to developing processes to support providers who participate in the assessments. This purpose of this paper is to explore the experiences of physicians and other clinicians assessing public long-term work disability related to mental disorders. Methods This is an exploratory and descriptive study using qualitative methods. Clinician input was gathered through focus groups and individual in-depth interviews. Verbatim transcripts were analyzed to identify recurrent and significant themes that arose during the focus groups and individual interviews. Results Many of the experiences that the clinicians in this sample discussed related to the difficulty of trying to fill the roles of advocate and medical expert as well as the challenge of determining the impact of functional capacity and work ability. The findings also highlight the current gap in knowledge about the factors that affect successful functioning in general and at work in particular. Conclusions Given the challenges created by the current state of knowledge, it may be useful to consider a category of “partial disability”. In addition, the fact that work disability depends on the interaction between the experience of the mental disorder and specific job requirements and the fact that people applying for public long-term disability are not working, it might be helpful to offer a clear description and guidelines of the meaning of work ability.

Recent mobile technologies have revolutionized the way people experience their environment. Although, there is only limited research on users' acceptance of AR in the cultural tourism context, previous researchers have explored the opportunities of using augmented reality (AR) in order to enhance user experience. Recent AR research lack works that integrates dimensions which are specific to cultural tourism and smart glass specific context. Hence, this work proposes an AR acceptance model in the context of cultural heritage tourism and smart glasses capable of performing augmented reality. Therefore, in this paper we aim to present an AR acceptance model to understand the AR usage behavior and visiting intention for tourists who use Smart Glass based AR at UNESCO cultural heritage destinations in Malaysia. Furthermore, this paper identifies information quality, technology readiness, visual appeal, and facilitating conditions as external variables and key factors influencing visitors' beliefs, attitudes and usage intention.

Rise and fall of competitiveness in individualistic and collectivistic societies

Leibbrandt, Andreas; Gneezy, Uri; List, John A.

2013-01-01

Competitiveness pervades life: plants compete for sunlight and water, animals for territory and food, and humans for mates and income. Herein we investigate human competitiveness with a natural experiment and a set of behavioral experiments. We compare competitiveness in traditional fishing societies where local natural forces determine whether fishermen work in isolation or in collectives. We find sharp evidence that fishermen from individualistic societies are far more competitive than fishermen from collectivistic societies, and that this difference emerges with work experience. These findings suggest that humans can evolve traits to specific needs, support the idea that socio-ecological factors play a decisive role for individual competitiveness, and provide evidence how individualistic and collectivistic societies shape economic behavior.

How Discourses of Biology Textbooks Work to Constitute Subjectivity: From the Ethical to the Colonial

NASA Astrophysics Data System (ADS)

Bazzul, Jesse

This thesis examines how discourses of biology textbooks can work to constitute various kinds of subjectivities. Using a Foucauldian archaeological approach to discourse analysis I examine how four Ontario secondary school biology textbooks discursively delimit what can be thought and acted upon, and in the process work to partially constitute students/teachers as sex/gendered; neocolonial; neoliberal (and a subject of work), and ethical subjects and subjectivities. This thesis engages the topic of how discourse can constitute subjectivity in science in three basic ways: First, on a theoretical level, in terms of working out an understanding of subject constitution/interpellation that would also be useful when engaging with other sociopolitical and ethical questions in science education. Secondly, in terms of an empirically based critical discourse analysis that examines how various statements within these four textbooks could set limits on what is possible for students to think and act upon in relation to themselves, science, and the world. Thirdly, this thesis represents a narrative of scholarly development that moves from an engagement of my personal experiences in science education and current science education literature towards the general politico-philosophical topic of subjectivity and biopolitics. This thesis begins with a discussion of my experiences as a science teacher, a review of relevant science education literature, and considerations of subjectivity that relate specifically ii to the specific methodological approach I employ when examining these textbooks. After this I present five chapters, each of which can be thought of as a somewhat separate analysis concerning how the discourses of these textbooks can work to constitute specific subjectivities (each involving different theoretical/methodological considerations). I conclude with a reflection/synthesis chapter and a call to see science education as a site for biopolitical struggle.

Schedule-Aware Workflow Management Systems

NASA Astrophysics Data System (ADS)

Mans, Ronny S.; Russell, Nick C.; van der Aalst, Wil M. P.; Moleman, Arnold J.; Bakker, Piet J. M.

Contemporary workflow management systems offer work-items to users through specific work-lists. Users select the work-items they will perform without having a specific schedule in mind. However, in many environments work needs to be scheduled and performed at particular times. For example, in hospitals many work-items are linked to appointments, e.g., a doctor cannot perform surgery without reserving an operating theater and making sure that the patient is present. One of the problems when applying workflow technology in such domains is the lack of calendar-based scheduling support. In this paper, we present an approach that supports the seamless integration of unscheduled (flow) and scheduled (schedule) tasks. Using CPN Tools we have developed a specification and simulation model for schedule-aware workflow management systems. Based on this a system has been realized that uses YAWL, Microsoft Exchange Server 2007, Outlook, and a dedicated scheduling service. The approach is illustrated using a real-life case study at the AMC hospital in the Netherlands. In addition, we elaborate on the experiences obtained when developing and implementing a system of this scale using formal techniques.

Accounting for substitution and spatial heterogeneity in a labelled choice experiment.

Lizin, S; Brouwer, R; Liekens, I; Broeckx, S

2016-10-01

Many environmental valuation studies using stated preferences techniques are single-site studies that ignore essential spatial aspects, including possible substitution effects. In this paper substitution effects are captured explicitly in the design of a labelled choice experiment and the inclusion of different distance variables in the choice model specification. We test the effect of spatial heterogeneity on welfare estimates and transfer errors for minor and major river restoration works, and the transferability of river specific utility functions, accounting for key variables such as site visitation, spatial clustering and income. River specific utility functions appear to be transferable, resulting in low transfer errors. However, ignoring spatial heterogeneity increases transfer errors. Copyright © 2016 Elsevier Ltd.

Meaning creation and employee engagement in home health caregivers.

PubMed

Nielsen, Mette Strange; Jørgensen, Frances

2016-03-01

The purpose of this study is to contribute to an understanding on how home health caregivers experience engagement in their work, and specifically, how aspects of home healthcare work create meaning associated with employee engagement. Although much research on engagement has been conducted, little has addressed how individual differences such as worker orientation influence engagement, or how engagement is experienced within a caregiving context. The study is based on a qualitative study in two home homecare organisations in Denmark using a think-aloud data technique, interviews and observations. The analysis suggests caregivers experience meaning in three relatively distinct ways, depending on their work orientation. Specifically, the nature of engagement varies across caregivers oriented towards being 'nurturers', 'professionals', or 'workers', and the sources of engagement differ for each of these types of caregivers. The article contributes by (i) advancing our theoretical understanding of employee engagement by emphasising meaning creation and (ii) identifying factors that influence meaning creation and engagement of home health caregivers, which should consequently affect the quality of services provided home healthcare patients. © 2015 Nordic College of Caring Science.

Therefore, this experience may prove useful to several patients, their families, and the experts helping them.We described an example of intervention aimed at guiding and facilitating a Williams Syndrome patient within a work environment, taking into consideration the peaks and valleys of these individuals' specific abilities.Based on our results, we also stressed the need to promote a set of projects and initiatives aimed at enhancing as much as possible self-sufficiency and psycho-affective balance in Williams Syndrome individuals, in order to protect their dignity and self-esteem.

The purpose of this study was to analyze the improvement of managerial skills of hospitals' top managers after a specific management training programme, and to explore possible predictors and relations. The study was conducted during the years 2006 and 2007 with cohort of 107 managers from 20 Serbian general hospitals. The managers self-assessed the improvement in their managerial skills before and after the training programme. After the training programme, all managers' skills had improved. The biggest improvement was in the following skills: organizing daily activities, motivating and guiding others, supervising the work of others, group discussion, and situation analysis. The least improved were: applying creative techniques, working well with peers, professional self-development, written communication, and operational planning. Identified predictors of improvement were: shorter years of managerial experience, type of manager, type of profession, and recognizing the importance of the managerial skills in oral communication, evidence-based decision making, and supervising the work of others. Specific training programme related to strategic management can increase managerial competencies, which are an important source of competitive advantage for organizations.

Our aim was to investigate the relationship between suppressing emotion and engaging with complaining customers at work and experience of depression and anxiety symptoms. We used nationally representative data from the Korean Working Condition Survey with 15,669 paid customer service workers. Job characteristics of "Engaging with Complaints", "Suppressing Emotion", experience of depression and anxiety symptoms were measured by self-reported questionnaires. Gender specific odds ratios (OR) and 95% confidence intervals (95% CI) were calculated using multivariate logistic regression after controlling for age, income, education level, job satisfaction, and working hours per week. The results showed that people who were 'Always Engaging with Complaints' (OR: 3.81, 95% CI: 1.83-7.96 for male, OR: 3.98, 95% CI: 2.07-7.66 for female) and 'Always Suppressing Emotion' (OR: 2.33, 95% CI: 1.33-4.08 for male, OR: 2.83, 95% CI: 1.67-4.77 for female) were more likely to experience depression and anxiety symptoms compared to those 'Rarely Engaging with Complaints' and 'Rarely Suppressing Emotion', respectively. Additionally, there was an interactive relationship between those job characteristics. Our nationwide study demonstrates that mental health problems are incrementally related to how much service workers must engage with complaining customers and suppressing emotion at work.

Nowadays, works of art can be enjoyed in both their original and reproduced format. The aim of this study was to investigate whether the format of a work of art could influence physiological and cognitive responses in beholders. Two abstract works of art and their digital reproductions were selected as experimental stimuli and displayed for 2min to 60 participants in a museum. HRV, HR, and RMSSD were recorded, while participants observed the works of art. Subsequently, participants provided behavioral ratings of color intensity, emotional intensity, aesthetic evaluation, perceived movement, and desire to touch the works of art. Results demonstrated that the faithful high-quality digital reproduction of works of art could be as arousing as the original works of art, but at the same time, they cannot replace the experience of standing in front of an authentic work of art in terms of explicit hedonic attributed values. Furthermore, specific interactions between individual inclinations to identify with fictional characters and acquired art competences in the context of aesthetic experience were found. © 2018 Elsevier B.V.

Park, YoungAh; Fritz, Charlotte

2015-03-01

Research has indicated the importance of recovery from work stress for employee well-being and work engagement. However, very little is known about the specific factors that may support or hinder recovery in the context of dual-earner couples. This study proposes spousal recovery support as a potential resource that dual-earner couples can draw on to enhance their recovery experiences and well-being. It was hypothesized that spousal recovery support would be related to the recipient spouse's life satisfaction via his or her own recovery experiences (i.e., psychological detachment, relaxation, and mastery experiences). The study further investigated the crossover of life satisfaction between working spouses as a potential outcome of recovery processes. Data from 318 full-time employed married couples in South Korea were analyzed using structural equation modeling. Results showed that spousal recovery support was positively related to all 3 recovery experiences of the recipient spouse. Moreover, this recovery support was related to the recipient spouse's life satisfaction via relaxation and mastery experiences. Unexpectedly, psychological detachment was negatively related to life satisfaction, possibly indicating a suppression effect. Life satisfaction crossed over between working spouses. No gender differences were found in the hypothesized paths. Based on these findings, theoretical and practical implications are discussed, and future research directions are presented.

The role of experience in night work: Lessons from two ergonomic studies.

PubMed

Pueyo, Valérie; Toupin, Cathy; Volkoff, Serge

2011-01-01

The purpose of this article is to analyze some connections between experience, health and work, especially in the field of night work. As a result of the baby boom, the proportion of elderly workers is steadily increasing, while at the same time many workers are reaching retirement age and being replaced by younger people. And, in the same time, there is an overall gradual increase in shift work and night work. To our knowledge, worker experience has not been extensively studied in this context. This was our focus in studying work activity in two very different situations, in a hospital and in a steel industry. In these two studies we observed that the experienced workers endeavor to plan ahead, especially at night. They do this to limit fatigue and to avoid emergencies and ensure that work is stress-free and as far as possible under control. But experience not only brings workers to plan ahead, it also enables them to do so, thanks to the resources it confers: gaining familiarity with tasks and acquiring the ability to identify critical situations, gaining knowledge about themselves and awareness of situations that cause difficulty; and gaining a better overview of the collective aspects of their work and of ways to share tasks or obtain assistance. They are able to undertake these strategies thanks to specific skills and capacities they have built along their professional career, which notably leads them to find the best trade-off between several goals, possibly contradictory. Such experience is especially valuable at night, when the worker is tired, and when there are fewer supervisors present. This experience can only be gained, however, if the work environment fosters its acquisition and provides an opportunity to make use of it, especially during the night shift and especially with respect to planning tasks ahead of time.

2015-10-14

The value of international health experience for doctors from developed nations is well recognised. Provisions have been made for medical staff in the United Kingdom to embark on work experiences abroad during their careers in the National Health Service. The London Deanery and Africa Health Placements provide an Out of Programme Experience for British General Practice trainee doctors wanting to work for a year in rural hospitals in South Africa. A qualitative study was conducted among fifteen British General Practice trainees who participated in the programme. The research aim was to understand the perceived benefit and value of their experience and their opinions about the structure of the programme. The data was analysed using thematic analysis. Their experience provided an accelerated year of learning and development that contributed to their professional and personal development. In addition to their general development, their improved ability to work in resource limited settings, enhancement of soft skills, a greater appreciation for the National Health Service and a better understanding of working within foreign health care systems were important gains. The timing of the experience, the security of re-employment on their return, assistance with administrative requirements of destination countries and the opportunity to gain varied, hands-on experience were highly valued components of the Out of Programme Experience. The value and benefits derived from the doctors' experience in South Africa are discussed in relation to another evaluation of the Out of Programme Experience, as well as issues of transferability of skills and competencies and future impacts on career decisions. This study provides evidence to suggest programmes such as the OOPE have the potential to create substantial benefits for trainee doctors, both in terms of their medical skills and competencies and through the development of softer skills. This programme, through the supply of scarce skills, further benefits the host country and specifically the health facilities and communities served by these trainee doctors.

Feature-Specific Event-Related Potential Effects to Action- and Sound-Related Verbs during Visual Word Recognition

Popp, Margot; Trumpp, Natalie M.; Kiefer, Markus

2016-01-01

Grounded cognition theories suggest that conceptual representations essentially depend on modality-specific sensory and motor systems. Feature-specific brain activation across different feature types such as action or audition has been intensively investigated in nouns, while feature-specific conceptual category differences in verbs mainly focused on body part specific effects. The present work aimed at assessing whether feature-specific event-related potential (ERP) differences between action and sound concepts, as previously observed in nouns, can also be found within the word class of verbs. In Experiment 1, participants were visually presented with carefully matched sound and action verbs within a lexical decision task, which provides implicit access to word meaning and minimizes strategic access to semantic word features. Experiment 2 tested whether pre-activating the verb concept in a context phase, in which the verb is presented with a related context noun, modulates subsequent feature-specific action vs. sound verb processing within the lexical decision task. In Experiment 1, ERP analyses revealed a differential ERP polarity pattern for action and sound verbs at parietal and central electrodes similar to previous results in nouns. Pre-activation of the meaning of verbs in the preceding context phase in Experiment 2 resulted in a polarity-reversal of feature-specific ERP effects in the lexical decision task compared with Experiment 1. This parallels analogous earlier findings for primed action and sound related nouns. In line with grounded cognitions theories, our ERP study provides evidence for a differential processing of action and sound verbs similar to earlier observation for concrete nouns. Although the localizational value of ERPs must be viewed with caution, our results indicate that the meaning of verbs is linked to different neural circuits depending on conceptual feature relevance.

Acquiring synaesthesia: insights from training studies

PubMed Central

Rothen, Nicolas; Meier, Beat

2014-01-01

Synaesthesia denotes a condition of remarkable individual differences in experience characterized by specific additional experiences in response to normal sensory input. Synaesthesia seems to (i) run in families which suggests a genetic component, (ii) is associated with marked structural and functional neural differences, and (iii) is usually reported to exist from early childhood. Hence, synaesthesia is generally regarded as a congenital phenomenon. However, most synaesthetic experiences are triggered by cultural artifacts (e.g., letters, musical sounds). Evidence exists to suggest that synaesthetic experiences are triggered by the conceptual representation of their inducer stimuli. Cases were identified for which the specific synaesthetic associations are related to prior experiences and large scale studies show that grapheme-color associations in synaesthesia are not completely random. Hence, a learning component is inherently involved in the development of specific synaesthetic associations. Researchers have hypothesized that associative learning is the critical mechanism. Recently, it has become of scientific and public interest if synaesthetic experiences may be acquired by means of associative training procedures and whether the gains of these trainings are associated with similar cognitive benefits as genuine synaesthetic experiences. In order to shed light on these issues and inform synaesthesia researchers and the general interested public alike, we provide a comprehensive literature review on developmental aspects of synaesthesia and specific training procedures in non-synaesthetes. Under the light of a clear working definition of synaesthesia, we come to the conclusion that synaesthesia can potentially be learned by the appropriate training. PMID:24624072

Communications and relationships between patient and nurse in Intensive Care Unit: knowledge, knowledge of the work, knowledge of the emotional state.

In an Intensive Care Unit (ICU) the communication between nurse and patient, the core of the care, is often hindered by patient's cognitive alterations and critical situation, by devices employed for the mechanical ventilation, and by the clinical and care-giving setting. How to overcome these barriers? How is the relational and communicative approach between nurse and patient unable to express him or herself to be managed? The available literature reveals that studies on communication with difficult patients, such as those treated in ICU are currently scarce. The present research offers a contribution in this respect, through fact-finding about the knowledge acquired by professional studies or work experiences, the personal and institutional techniques implemented in regards to communication (knowledge of the work), the relational behaviours and the emotional experience with patients (knowledge of the emotional state) of nurses working in the Intensive Care Units. A semi-structured interview have been designed and submitted to 30 nurses working in fourteen Highly Specialized Centres (HUB) in Emilia Romagna, Italy. Two nurses with different years of experience in the field have been chosen for each Operating Unit. According to the interviewees paraverbal communication is the most common way to communicate with patients: different strategies are employed such as facial expression or lip movement. In any case, the nurse has the task to choose the most suitable technique according to his or her experiences, his or her knowledge and the patient him or herself. The results claim that lack of specific training on communicative aspects of care, should be combined with an attitude of being prone to listening to and understanding the needs of the patient and of his or her family as well. The interviewees declare they have a solid preparation in the bio-clinical aspect of care, but both new hired nurses and experts affirm that they need a specific training in relational and communicative aspects, proving its importance.

Mounting evidence suggests that multiple mechanisms underlie working memory capacity. Using transcranial direct current stimulation (tDCS), the current study aimed to provide causal evidence for the neural dissociation of two mechanisms underlying visual working memory (WM) capacity, namely, the scope and control of attention. A change detection task with distractors was used, where a number of colored bars (i.e., two red bars, four red bars, or two red plus two blue bars) were presented on both sides (Experiment 1) or the center (Experiment 2) of the screen for 100ms, and participants were instructed to remember the red bars and to ignore the blue bars (in both Experiments), as well as to ignore the stimuli on the un-cued side (Experiment 1 only). In both experiments, participants finished three sessions of the task after 15min of 1.5mA anodal tDCS administered on the right prefrontal cortex (PFC), the right posterior parietal cortex (PPC), and the primary visual cortex (VC), respectively. The VC stimulation served as an active control condition. We found that compared to stimulation on the VC, stimulation on the right PPC specifically increased the visual WM capacity under the no-distractor condition (i.e., 4 red bars), whereas stimulation on the right PFC specifically increased the visual WM capacity under the distractor condition (i.e., 2 red bars plus 2 blue bars). These results suggest that the PPC and PFC are involved in the scope and control of attention, respectively. We further showed that compared to central presentation of the stimuli (Experiment 2), bilateral presentation of the stimuli (on both sides of the fixation in Experiment 1) led to an additional demand for attention control. Our results emphasize the dissociated roles of the frontal and parietal lobes in visual WM capacity, and provide a deeper understanding of the neural mechanisms of WM. Copyright © 2017 Elsevier Inc.

Working memory affects false memory production for emotional events.

PubMed

Mirandola, Chiara; Toffalini, Enrico; Ciriello, Alfonso; Cornoldi, Cesare

2017-01-01

Whereas a link between working memory (WM) and memory distortions has been demonstrated, its influence on emotional false memories is unclear. In two experiments, a verbal WM task and a false memory paradigm for negative, positive or neutral events were employed. In Experiment 1, we investigated individual differences in verbal WM and found that the interaction between valence and WM predicted false recognition, with negative and positive material protecting high WM individuals against false remembering; the beneficial effect of negative material disappeared in low WM participants. In Experiment 2, we lowered the WM capacity of half of the participants with a double task request, which led to an overall increase in false memories; furthermore, consistent with Experiment 1, the increase in negative false memories was larger than that of neutral or positive ones. It is concluded that WM plays a critical role in determining false memory production, specifically influencing the processing of negative material.

Is inattentional blindness related to individual differences in visual working memory capacity or executive control functioning?

PubMed

Hannon, Emily M; Richards, Anne

2010-01-01

Inattentional blindness (IB) research deals with situations where, under focused attention tasks, salient stimuli that are irrelevant to that task do not reach conscious awareness. Although such research has captured popular imagination, to date very little research has been conducted on whether some are more likely to experience this phenomenon than others. Here we provide evidence that working memory capacity (WMC) contributed to this experience, with lower WMC being predictive of IB. We also investigated whether IB could be more readily explained in terms of domain-specific visual WMC. No group differences in visual WMC were found, nor any differences in the ability to perform the primary IB task. These findings suggest that differences in higher-order executive control of attention contributes to the experience of IB.

A number of general studies that were proposed for the PPEPL-SHUTTLE program are considered in qualitative detail from both the theoretical and practical points of view. The selection of experimental programs was restricted to those which may be considered active as opposed to refinements of the passive observational programs done previously. It is concluded that, while these new studies were scientifically worthwhile and could be performed in principle, in most cases insufficient attention was paid to the practical details of the experiments. Several specific areas of study, stressing in particular the practical feasibility of the proposed experiments, are recommended. In addition, recommendations are made for further theoretical study, where appropriate. For Vol. 1, see N74-28169; for Vol. 2, see N74-28170.

When study abroad experience fails to deliver: The internal resources threshold effect

Some second language (L2) learners return from study abroad experiences with seemingly no change in their L2 ability. In this study we investigate whether a certain level of internal cognitive resources is necessary in order for individuals to take full advantage of the study abroad experience. Specifically, we examined the role of working memory resources in lexical comprehension and production for learners who had or had not studied abroad. Participants included native English learners of Spanish. Participants completed a translation recognition task and a picture-naming task. The results suggest that individuals who lack a certain threshold of working memory resources are unable to benefit from the study abroad context in terms of being able to produce accurately in the L2.

Research suggests experiences with police are related to human immunodeficiency virus (HIV) sexual risk among women working as sex workers. However, little is known about the links between specific police-related behaviors and HIV vulnerability. We examine whether 5 police-related experiences are associated with measures of HIV risk and violence among a sample of female sex workers (FSWs) in Andhra Pradesh, India, and consider the implications for HIV prevention. FSWs at least 18 years of age (n = 835) were recruited through respondent-driven sampling for a cross-sectional survey conducted as part of Avahan, the India AIDS Initiative. Using logistic regression models adjusted for age, age at start of sex work, and sex work venue, we assessed police-related experiences reported by FSWs in relation to HIV risk behaviors and violence. Results showed having sex with police to avoid trouble, giving gifts to police to avoid trouble, having police take condoms away, experiencing a workplace raid, and being arrested were associated with sexually transmitted infection symptoms, inconsistent condom use, acceptance of more money for sex without a condom, and experience of client violence. These findings suggest a need for interventions targeting police-FSW interactions to reduce HIV vulnerability among FSWs.

Drawing the eczema aesthetic: the psychological effects of chronic skin disease as depicted in the works of John Updike, Elizabeth Bishop, and Zelda Fitzgerald.

PubMed

Tatum, Karen E

2010-06-01

How might the psycho-social effects of chronic skin disease, its treatments (and discontents) be figuratively expressed in writing and painting? Does the art reveal common denominators in experience and representation? If so, how do we understand the cryptic language of these expressions? By examining the works of artists with chronic skin diseases--John Updike, Elizabeth Bishop, and Zelda Fitzgerald--some common features can be noted. Chronically broken skin can fracture the ego or self-perception, resulting in a disturbed body image, which leads to personality disorders and co-morbid affective disorders such as anxiety and depression. The vertiginous feeling that results can be noted in the paradoxical characters, figures, and psyches portrayed in the works of these artists. This essay will examine the more specific ways in which artists disclose and/or conceal their experiences and the particular ways in which these manifest in their works. While certain nuances exist, the common denominators give us a starting point for developing an eczema aesthetic, a code for interpreting the ways in which artists' experiences with skin disease manifest in their works.

Côté, Daniel; Coutu, Marie-France

2010-01-01

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

Well-being of nursing staff on specialized units for older patients with combined care needs.

2018-03-01

Working in long-term care is seen as a stressful, physically and mentally demanding occupation, and thus, nursing staff are at risk for work and stress-related diseases. In older patients, psychiatric illnesses often occur in combination with physical illnesses, requiring nursing care that is specific to these combined care needs. The impact of caring for these patients on the mental well-being of nurses is unknown. Nursing staff working on specialized units for patients with combined care needs experience high levels of self-efficacy in combination with strong feelings of self-rated competence. Although levels of burnout are relatively low, mental healthcare nursing staff is more at risk for burnout when working in specialized settings for patients with combined care needs than nursing home staff working in specialized settings for these patients. Nursing staff characteristics, such as years of working experience and age, seem more important in relation to staff well-being than patient characteristics in specialized settings for combined care needs. Staff well-being might benefit from specializing care, so that patients with similar care needs are placed together and care is focused. The presence of specialized care units for older patients with combined care needs can allow for both targeted and focused allocation of nursing staff to these units and provision of specific training. Introduction In older patients, psychiatric illnesses frequently exist in tandem with physical illnesses, requiring nursing care that is specific to these combined care needs. The impact of caring for these patients on the mental well-being of nursing staff is unknown. To investigate whether care characteristics of patients with combined care needs are related to the mental well-being of nursing staff. Well-being of nursing staff was studied within a larger exploratory observational cross-sectional study that examined the differences and similarities of specialized combined care units in Dutch mental healthcare and nursing home settings. Nursing staff across settings, with more than 5 years of work experience, felt competent in caring for patients with combined care needs. No significant effects of care characteristics of patients with combined care needs on the work-related well-being of nursing staff were shown. Both mental health nursing staff and older employees, however, were found to be more at risk for burnout. Staff well-being might benefit from placing patients with combined care needs together, so care is focused. The presence of specialized care units can allow for both targeted and focused allocation of nursing staff to these units and provision of specific training. © 2017 John Wiley & Sons Ltd.

Reading literary fiction improves theory of mind.

Understanding others' mental states is a crucial skill that enables the complex social relationships that characterize human societies. Yet little research has investigated what fosters this skill, which is known as Theory of Mind (ToM), in adults. We present five experiments showing that reading literary fiction led to better performance on tests of affective ToM (experiments 1 to 5) and cognitive ToM (experiments 4 and 5) compared with reading nonfiction (experiments 1), popular fiction (experiments 2 to 5), or nothing at all (experiments 2 and 5). Specifically, these results show that reading literary fiction temporarily enhances ToM. More broadly, they suggest that ToM may be influenced by engagement with works of art.

Experiencing work as a daily challenge: the case of scleroderma.

Little is known about the physical and discretionary aspects of work that people with scleroderma (SSc) find difficult. This article describes the findings from a study that explored the challenges and adaptations made by individuals with SSc to continue to work. Thirty-two employed individuals with SSc participated. Participants were predominantly women (82%), white (79%), and well educated (M = 16.9 years). The average age was 47.3 years, and 60.6% were married. Mean disease duration was 9.7 years, and 56.2% had diffuse SSc. Mean years on the job was 10.2 (SD ± 8.8), and 71.9% worked at least 35 hours per week. Participants engaged in a single structured interview about work-related challenges and adaptations. Content and thematic analysis was used to identify key themes across the interviews. Employees with SSc experienced Work as a daily challenge. This central theme described the general work experience for most participants. Three subthemes described their specific experiences: The work environment: Opportunities, challenges, and accommodations; Career planning; and Supportive others. The participants were anxious to find scenarios that allowed them to continue to work. Worksite accommodations and flexibility in scheduling can make the difference between working and disability.

Less than 40% of people with disabilities work. Many studies have detailed the barriers to employment but few have examined the work experiences of those who are employed. A description of work conditions valued by a specific segment of employed people with disabilities is provided. Videotaped interviews of 33 successfully employed people with mobility impairments and limitations (PWMIL) were transcribed and analyzed to gather their perspectives on their work social and physical environments. Finding work was facilitated by family, friends and other social networks, vocational services, and prior education. Doing volunteer work, spending time at a paid and unpaid internship, and part-time work experiences were important aspects of job acquisition. Exterior and interior physical features were or had been made accessible. Expensive assistive technologies were paid for by the employee and their health insurance. Almost all personal assistance was provided by family, friends and co-workers. Work satisfaction included having a supportive employer, supportive co-workers, and flexible worksite policies. The interviews of employed PWMIL provide prospective employers and employees information on important social and physical work features that are needed to improve the possibilities for hiring people with disabilities and facilitating their successful careers.

Content-specificity in verbal recall: a randomized controlled study.

PubMed

Zirk-Sadowski, Jan; Szucs, Denes; Holmes, Joni

2013-01-01

In this controlled experiment we examined whether there are content effects in verbal short-term memory and working memory for verbal stimuli. Thirty-seven participants completed forward and backward digit and letter recall tasks, which were constructed to control for distance effects between stimuli. A maximum-likelihood mixed-effects logistic regression revealed main effects of direction of recall (forward vs backward) and content (digits vs letters). There was an interaction between type of recall and content, in which the recall of digits was superior to the recall of letters in verbal short-term memory but not in verbal working memory. These results demonstrate that the recall of information from verbal short-term memory is content-specific, whilst the recall of information from verbal working memory is content-general.

How visual working memory contents influence priming of visual attention.

PubMed

Carlisle, Nancy B; Kristjánsson, Árni

2017-04-12

Recent evidence shows that when the contents of visual working memory overlap with targets and distractors in a pop-out search task, intertrial priming is inhibited (Kristjánsson, Sævarsson & Driver, Psychon Bull Rev 20(3):514-521, 2013, Experiment 2, Psychonomic Bulletin and Review). This may reflect an interesting interaction between implicit short-term memory-thought to underlie intertrial priming-and explicit visual working memory. Evidence from a non-pop-out search task suggests that it may specifically be holding distractors in visual working memory that disrupts intertrial priming (Cunningham & Egeth, Psychol Sci 27(4):476-485, 2016, Experiment 2, Psychological Science). We examined whether the inhibition of priming depends on whether feature values in visual working memory overlap with targets or distractors in the pop-out search, and we found that the inhibition of priming resulted from holding distractors in visual working memory. These results are consistent with separate mechanisms of target and distractor effects in intertrial priming, and support the notion that the impact of implicit short-term memory and explicit visual working memory can interact when each provides conflicting attentional signals.

The differential impact of job isostrain and home-work interference on indicators of physical and mental health in women and men.

To evaluate (1) whether the physical and mental health of male workers differs from that of female workers, and, if so, whether (2) this is affected by the interplay between work and nonwork burden. We pooled two large Belgian databases (BELSTRESS III, SOMSTRESS) comprising data on 4810 (2847 women). Gender-specific logistic regressions were performed using a four-level variable as predictor. This combined two predictors: isolated job strain (isostrain) and home-work interference (HWI). Male workers are at greater risk of chronic fatigue when they experience high isostrain but not high HWI. Although accumulated high isostrain and high HWI affect women mainly via chronic fatigue, the same pattern has a greater impact on men's perceived health. There was no difference for the other patterns. To improve workers' well-being, organizations should develop work and nonwork balance policies specific for men and women.

Integrated support structure for GASCAN 2

NASA Technical Reports Server (NTRS)

1990-01-01

The focus of the Worcester Polytechnic Institute (WPI) Advanced Space Design Program was the preliminary design of the Integrated Support Structure for GASCAN II, a Get Away Special canister donated by the MITRE Corporation. Two teams of three students each worked on the support structure. There was a structural design team and a thermal design team. The structure will carry three experiments also undergoing preliminary design this year, the mu-gravity Ignition Experiment, the Rotational Flow in Low Gravity Experiment, and the Ionospheric Properties and Propagation Experiment. The structural design team was responsible for the layout of the GASCAN and the preliminary design of the structure itself. They produced the physical interface specifications defining the baseline weights and volumes for the equipment and produced layout drawings of the system. The team produced static and modal finite element analysis of the structure using ANSYS. The thermal design team was responsible for the power and timing requirements of the payload and for the identification and preliminary analysis of potential thermal problems. The team produced the power, timing, and energy interface specifications and assisted in the development of the specification of the battery pack. The thermal parameters of each experiment were cataloged and the experiments were subjected to worst case heat transfer scenarios.

This study looked at the influences on the return to work (RTW) in the first 2 years for people severely injured in the 22 February 2011 Christchurch earthquake. We used a constructivist grounded theory approach using semi-structured interviews to collect data from 14 people injured in the earthquake. Analysis elicited three themes that appeared to influence the process of RTW following the Christchurch earthquake. Living the earthquake experience, the individual's experiences of the earthquake and how their injury framed their expectations; rebuilding normality, the desire of the participants to return to life as it was; while dealing with the secondary effects of the earthquake includes the earthquake specific effects which were both barriers and facilitators to returning to work. The consequences of the earthquake impacted on experience, process and outcome of RTW for those injured in the Christchurch Earthquake. Work and RTW appeared key tools to enhance recovery after serious injury following the earthquake. The altered physical, social and economic environment must be considered when working on the return to work (RTW) of individuals with earthquake injuries. Providing tangible emotional and social support so injured earthquake survivors feel safe in their workplace may facilitate RTW. Engaging early with employers may assist the RTW of injured earthquake survivors.

Our aim was to investigate the relationship between suppressing emotion and engaging with complaining customers at work and experience of depression and anxiety symptoms. We used nationally representative data from the Korean Working Condition Survey with 15,669 paid customer service workers. Job characteristics of “Engaging with Complaints”, “Suppressing Emotion”, experience of depression and anxiety symptoms were measured by self-reported questionnaires. Gender specific odds ratios (OR) and 95% confidence intervals (95% CI) were calculated using multivariate logistic regression after controlling for age, income, education level, job satisfaction, and working hours per week. The results showed that people who were ‘Always Engaging with Complaints’ (OR: 3.81, 95% CI: 1.83–7.96 for male, OR: 3.98, 95% CI: 2.07–7.66 for female) and ‘Always Suppressing Emotion’ (OR: 2.33, 95% CI: 1.33–4.08 for male, OR: 2.83, 95% CI: 1.67–4.77 for female) were more likely to experience depression and anxiety symptoms compared to those ‘Rarely Engaging with Complaints’ and ‘Rarely Suppressing Emotion’, respectively. Additionally, there was an interactive relationship between those job characteristics. Our nationwide study demonstrates that mental health problems are incrementally related to how much service workers must engage with complaining customers and suppressing emotion at work.

2014-07-01

This qualitative study aims to examine Japanese women undergraduate engineering students' experiences of interacting with departmental peers of the same year in the laboratory setting by using interview data of 32 final-year students at two modestly selective national universities in Japan. Expectation state theory that explains unequal relationship between men and women is used as a framework. Findings suggest that women generally had a discouraging experience while working with their male peers. Specifically, women participated less and lost confidence by comparing with the men who appeared to be confident and competent.

Experience report: Using formal methods for requirements analysis of critical spacecraft software

NASA Technical Reports Server (NTRS)

Lutz, Robyn R.; Ampo, Yoko

1994-01-01

Formal specification and analysis of requirements continues to gain support as a method for producing more reliable software. However, the introduction of formal methods to a large software project is difficult, due in part to the unfamiliarity of the specification languages and the lack of graphics. This paper reports results of an investigation into the effectiveness of formal methods as an aid to the requirements analysis of critical, system-level fault-protection software on a spacecraft currently under development. Our experience indicates that formal specification and analysis can enhance the accuracy of the requirements and add assurance prior to design development in this domain. The work described here is part of a larger, NASA-funded research project whose purpose is to use formal-methods techniques to improve the quality of software in space applications. The demonstration project described here is part of the effort to evaluate experimentally the effectiveness of supplementing traditional engineering approaches to requirements specification with the more rigorous specification and analysis available with formal methods.

A young person's game: immersion and distancing in bar work.

PubMed

Conway, Thomas; MacNeela, Pádraig

2012-01-01

Previous research indicates that bar workers report high levels of alcohol consumption, but the bar work experience itself has been little studied as a means to understand health threats associated with this job role. The subjective experience and meaning of bar work was explored in this study by interviewing current and ex-bar workers from a district in an Irish city that had a high density of bars and busy tourism industry. A total of 12 participants took part in focus groups (FGs) and seven in individual interviews. Four themes were identified in a thematic analysis. The central depiction of bar work was of an initial immersion in an intensive lifestyle characterised by heavy drinking, with subsequent distancing from the extremes of the lifestyle. The participants affiliated strongly with the bar work occupational identity, which included alcohol use in group scenarios for drinking during work, after work and on time off. The bar work lifestyle was most intense in the 'superpub' environment, characterised by permissive staff drinking norms and reported stress. Although an important identity, bar work was ultimately a transient role. The findings are considered in relation to research on occupation-specific stress and alcohol use, social identity and developmental needs in young adulthood.

The biophysical basis of Benveniste experiments: Entropy, structure, and information in water

NASA Astrophysics Data System (ADS)

Widom, Allan; Srivastava, Yogendra; Valenzi, Vincenzo

Benveniste had observed that highly dilute (and even in the absence of physical molecules) biological agents still triggered relevant biological systems. Some of these experiments were reproduced in three other laboratories who cosigned the article, (Davenas et al., Nature 1988, 333, 816). Further works, [(Medical Hypotheses 2000, 54, 33), (Rivista di Biologia/Biology Forum 97, 2004, 169)], showed that molecular activity in more than 50 biochemical systems and even in bacteria could be induced by electromagnetic signals transferred through water solutes. The sources of the electromagnetic signals were recordings of specific biological activities. These results suggest that electromagnetic transmission of biochemical information can be stored in the electric dipole moments of water in close analogy to the manner in which magnetic moments store information on a computer disk. The electromagnetic transmission would enable in vivo transmissions of the specific molecular information between two functional biomolecules. In the present work, the physical nature of such biological information storage and retrieval in ordered quantum electromagnetic domains of water will be discussed.

During the last two decades, understanding and experience of microsurgical reconstruction have increased. This is linked to improved instruments and technical devices, as well as to the increased number of available donor sites for microvascular flap transfer. If the indication is appropriate, it is now possible to perform personalised, safe and successful microsurgical reconstructions, almost independently of the patients' age. Despite these constant developments, there is little specific literature on microsurgery related to the specific problems of the elderly patient. During two consensus workshops organised by the DAM (German Speaking Working Group for Microsurgery of the Peripheral Nerves and Vessels), the latest findings and experience with microsurgical reconstruction in the elderly patient were presented by a group of experts and current recommendations were formulated. On the basis of these consensus workshops and the current literature, this article discusses important issues in this area. Georg Thieme Verlag KG Stuttgart · New York.

Selective visual working memory in fear of spiders: the role of automaticity and material-specificity.

PubMed

Reinecke, Andrea; Becker, Eni S; Rinck, Mike

2009-12-01

Following cognitive models of anxiety, biases occur if threat processing is automatic versus strategic. Therefore, most of these models predict attentional bias, but not explicit memory bias. We suggest dividing memory into the highly automatic working memory (WM) component versus long-term memory when investigating bias in anxiety. WM for threat has rarely been investigated although its main function is stimulus monitoring, particularly important in anxiety. We investigated WM for spiders in spider fearfuls (SFs) versus non-anxious controls (NACs). In Experiment 1 (23 SFs/24 NACs), we replicated an earlier WM study, reducing strategic processing options. This led to stronger group differences and, thus, clearer WM threat biases. There were no group differences in Experiment 2 (18 SFs/19 NACs), using snakes instead of spiders to test whether WM biases are material-specific. This article supports cognitive models of anxiety in that biases are more likely to occur when reducing strategic processing. However, it contradicts the assumption that explicit memory biases are not characteristic of anxiety.

This paper proposes an engineering management model for NASA's future space exploration missions based on past experiences working with the International Partners of the International Space Station. The authors have over 25 years of combined experience working with the European Space Agency, Japan Aerospace Exploration Agency, Canadian Space Agency, Italian Space Agency, Russian Space Agency, and their respective contractors in the design, manufacturing, verification, and integration of their elements electric power system into the United States on-orbit segment. The perspective presented is one from a specific sub-system integration role and is offered so that the lessons learned from solving issues of technical and cultural nature may be taken into account during the formulation of international partnerships. Descriptions of the types of unique problems encountered relative to interactions between international partnerships are reviewed. Solutions to the problems are offered, taking into consideration the technical implications. Through the process of investigating each solution, the important and significant issues associated with working with international engineers and managers are outlined. Potential solutions are then characterized by proposing a set of specific methodologies to jointly develop spacecraft configurations that benefits all international participants, maximizes mission success and vehicle interoperability while minimizing cost.

Twelve tips for overnight teaching.

2014-03-01

The European Working Time Directive and the United States' duty hour restrictions have changed resident physicians' schedules, specifically increasing overnight shifts and decreasing overall time spent in the hospital. As residents' perception of night shifts is that they have little educational value, efforts to improve educational opportunities and night attending teaching are desirable. However, resources about and recommendations for best practices for overnight teaching by faculty are scarce. To provide 12 tips to highlight strategies intended to optimize attending physicians' overnight teaching skills and strategies. The tips provided are based on our experiences and reflections as in-house faculty supervising residents working overnight, by our experience and group discussions as medical educators, and the available literature. The 12 tips presented offer specific strategies to optimize attending physicians' overnight teaching for resident physicians, specifically highlighting the unique logistics, pedagogy and follow-up of overnight teaching. Preparation for teaching is important in any environment, but understanding the unique timing and circumstances associated with overnight teaching is vital to ensure that overnight teaching is effective. Acknowledging and addressing the physical and cognitive obstacles associated with overnight teaching and learning is necessary to maximize the educational value of overnight teaching.

Disgust as Embodied Moral Judgment

PubMed Central

Schnall, Simone; Haidt, Jonathan; Clore, Gerald L.; Jordan, Alexander H.

2008-01-01

How, and for whom, does disgust influence moral judgment? In 4 experiments participants made moral judgments while experiencing extraneous feelings of disgust. Disgust was induced in Experiment 1 by exposure to a bad smell, in Experiment 2 by working in a disgusting room, in Experiment 3 by recalling a physically disgusting experience, and in Experiment 4 through a video induction. In each case, the results showed that disgust can increase the severity of moral judgments relative to controls. Experiment 4 found that disgust had a different effect on moral judgment than did sadness. In addition, Experiments 2-4 showed that the role of disgust in severity of moral judgments depends on participants’ sensitivity to their own bodily sensations. Taken together, these data indicate the importance - and specificity - of gut feelings in moral judgments. PMID:18505801

Working memory and spatial judgments: Cognitive load increases the central tendency bias.

PubMed

Allred, Sarah R; Crawford, L Elizabeth; Duffy, Sean; Smith, John

2016-12-01

Previous work demonstrates that memory for simple stimuli can be biased by information about the distribution of which the stimulus is a member. Specifically, people underestimate values greater than the distribution's average and overestimate values smaller than the average. This is referred to as the central tendency bias. This bias has been explained as an optimal use of both noisy sensory information and category information. In largely separate literature, cognitive load (CL) experiments attempt to manipulate the available working memory of participants in order to observe the effect on choice or judgments. In two experiments, we demonstrate that participants under high cognitive load exhibit a stronger central tendency bias than when under a low cognitive load. Although not anticipated at the outset, we also find that judgments exhibit an anchoring bias not described previously.

Work rehabilitation programs targeting different client groups are available in nearly all major hospital occupational therapy departments in Hong Kong. Clients receiving work rehabilitation are referred from various out-patient clinics and other occupational therapists. Those clients experience limitation in work after their injuries or diseases and plan to return to work after rehabilitation. Program objectives are 1) to assist clients to reach maximum work capacity as rapidly as possible 2) to ensure clients return to work safely 3) to improve clients' work readiness. This case report describes an individualized work simulation program at a general hospital in Hong Kong provided for a typical client who is preparing to return to his worker role.

Livingston, Beth A; Judge, Timothy A

2008-01-01

The present study tested the effect of work-family conflict on emotions and the moderating effects of gender role orientation. On the basis of a multilevel design, the authors found that family-interfering-with- work was positively related to guilt, and gender role orientation interacted with both types of conflict (work-interfering-with-family and family-interfering-with-work) to predict guilt. Specifically, in general, traditional individuals experienced more guilt from family-interfering-with-work, and egalitarian individuals experienced more guilt from work-interfering-with-family. Additionally, a higher level interaction indicated that traditional men tended to experience a stronger relationship between family-interfering-with-work and guilt than did egalitarian men or women of either gender role orientation. 2008 APA

Experiences and psychological distress of fertility treatment and employment.

PubMed

Payne, Nicola; Seenan, Susan; van den Akker, Olga

2018-04-16

This study examined experiences and psychological distress about fertility treatment in people combining work and treatment. Five hundred and sixty-three participants in the UK completed an online survey asking about difficulties in combining work and treatment; workplace disclosure, support, absence and policy; and psychological distress about treatment. Absence from work and perceptions that treatment has an impact on work and career prospects were reported by the majority of participants and this was related to the psychological distress of treatment. Around three quarters of participants disclosed to their employer and colleagues. The key reason for disclosure was needing to ask for absence from work and the main reason for non-disclosure was privacy. Workplace policy relating to managing fertility treatment and support from colleagues and their employer was related to reduced psychological distress but workplace policy was reported by less than one quarter of participants. Difficulties experienced in combining work and treatment suggest that support is needed. Specific workplace policy, guidance for supervisors and flexibility in fertility clinic times should help support employees during treatment and reduce psychological distress, thereby potentially influencing physical health and treatment outcomes.

Role of clinical tutors in volunteering work camps.

Alloni, Rossana; D'Elia, Annunziata; Navajas, Francisca; De Gara, Laura

2014-04-01

The Università Campus Bio-Medico (Italy) promotes a summer volunteering work camp (Workcamp Perù) as a social activity for medical and non-medical students. Some junior doctors participate as 'clinical tutors', together with tutors from other professions; all clinical tutors have some teaching experience in our teaching hospital. The campsite is located in the South of Peru in the Cañete Valley, an area characterised by extreme poverty and a severe lack of infrastructure. During the five Workcamp Perù trips that have been organised so far, health science students have carried out many activities for disease prevention and health education, and bio-medical engineering students have organised sessions on the safety of electrical installations, for accident prevention. We observed that in this setting tutorial activity is fundamental, because it not only offers students an opportunity to learn but also encourages them to react in a more personal and reflective manner to various stressful situations, which often occur in the work camp. The professional competence of the tutor plays an important role before the work camp, in defining the learning objectives for the students and involving them in training sessions held prior to the work camp. Also, during the camp, tutors work with students and also direct the daily briefing and debriefing sessions that are the most important learning activity. For medical tutors involved in the work camp the volunteering experience is a challenge for developing their specific professional and teaching skills, but it also provides an enriching experience in both professional and personal terms. We consider these work camps to be a useful experience in the training of our clinical tutors. © 2014 John Wiley & Sons Ltd.

Macroscopic relationship in primal-dual portfolio optimization problem

NASA Astrophysics Data System (ADS)

Shinzato, Takashi

2018-02-01

In the present paper, using a replica analysis, we examine the portfolio optimization problem handled in previous work and discuss the minimization of investment risk under constraints of budget and expected return for the case that the distribution of the hyperparameters of the mean and variance of the return rate of each asset are not limited to a specific probability family. Findings derived using our proposed method are compared with those in previous work to verify the effectiveness of our proposed method. Further, we derive a Pythagorean theorem of the Sharpe ratio and macroscopic relations of opportunity loss. Using numerical experiments, the effectiveness of our proposed method is demonstrated for a specific situation.

Formal Methods of V&V of Partial Specifications: An Experience Report

NASA Technical Reports Server (NTRS)

Easterbrook, Steve; Callahan, John

1997-01-01

This paper describes our work exploring the suitability of formal specification methods for independent verification and validation (IV&V) of software specifications for large, safety critical systems. An IV&V contractor often has to perform rapid analysis on incomplete specifications, with no control over how those specifications are represented. Lightweight formal methods show significant promise in this context, as they offer a way of uncovering major errors, without the burden of full proofs of correctness. We describe an experiment in the application of the method SCR. to testing for consistency properties of a partial model of requirements for Fault Detection Isolation and Recovery on the space station. We conclude that the insights gained from formalizing a specification is valuable, and it is the process of formalization, rather than the end product that is important. It was only necessary to build enough of the formal model to test the properties in which we were interested. Maintenance of fidelity between multiple representations of the same requirements (as they evolve) is still a problem, and deserves further study.

A history of studies that examine the interactions of Toxoplasma with its host cell: Emphasis on in vitro models.

Boyle, Jon P; Radke, Jay R

2009-07-01

This review is a historical look at work carried out over the past 50 years examining interactions of Toxoplasma with the host cell and attempts to focus on some of the seminal experiments in the field. This early work formed the foundation for more recent studies aimed at identifying the host and parasite factors mediating key Toxoplasma-host cell interactions. We focus especially on those studies that were performed in vitro and provide discussions of the following general areas: (i) establishment of the parasitophorous vacuole, (ii) the requirement of specific host cell molecules for parasite replication, (iii) the scenarios under which the host cell can resist parasite replication and/or persistence, (iv) host species-specific and host strain-specific responses to Toxoplasma infection, and (v) Toxoplasma-induced immune modulation.

Directed Forgetting and Directed Remembering in Visual Working Memory

PubMed Central

Williams, Melonie; Woodman, Geoffrey F.

2013-01-01

A defining characteristic of visual working memory is its limited capacity. This means that it is crucial to maintain only the most relevant information in visual working memory. However, empirical research is mixed as to whether it is possible to selectively maintain a subset of the information previously encoded into visual working memory. Here we examined the ability of subjects to use cues to either forget or remember a subset of the information already stored in visual working memory. In Experiment 1, participants were cued to either forget or remember one of two groups of colored squares during a change-detection task. We found that both types of cues aided performance in the visual working memory task, but that observers benefited more from a cue to remember than a cue to forget a subset of the objects. In Experiment 2, we show that the previous findings, which indicated that directed-forgetting cues are ineffective, were likely due to the presence of invalid cues that appear to cause observers to disregard such cues as unreliable. In Experiment 3, we recorded event-related potentials (ERPs) and show that an electrophysiological index of focused maintenance is elicited by cues that indicate which subset of information in visual working memory needs to be remembered, ruling out alternative explanations of the behavioral effects of retention-interval cues. The present findings demonstrate that observers can focus maintenance mechanisms on specific objects in visual working memory based on cues indicating future task relevance. PMID:22409182

To develop a self-report scale of subjective experiences of illness perceived to impact on employment functioning, as an alternative to a diagnostic perspective, for anticipating the vocational assistance needs of people with schizophrenia or schizoaffective disorders. A repeated measures pilot study (n(1) = 26, n(2) = 21) of community residents with schizophrenia identified a set of work-related subjective experiences perceived to impact on employment functioning. Items with the best psychometric properties were applied in a 12 month longitudinal survey of urban residents with schizophrenia or schizoaffective disorder (n(1) = 104; n(2) = 94; n(3) = 94). Construct validity, factor structure, responsiveness, internal consistency, stability, and criterion validity investigations produced favourable results. Work-related subjective experiences provide information about the intersection of the person, the disorder, and expectations of employment functioning, which suggest new opportunities for vocational professionals to explore and discuss individual assistance needs. Further psychometric investigations of test-retest reliability, discriminant and predictive validity, and research applications in supported employment and vocational rehabilitation, are recommended. Subject to adequate psychometric properties, the new measure promises to facilitate exploring: individuals' specific subjective experiences; how each is perceived to contribute to employment restrictions; and the corresponding implications for specialized treatment, vocational interventions and workplace accommodations.

Health care voluntourism: addressing ethical concerns of undergraduate student participation in global health volunteer work.

PubMed

McCall, Daniel; Iltis, Ana S

2014-12-01

The popularity and availability of global health experiences has increased, with organizations helping groups plan service trips and companies specializing in "voluntourism," health care professionals volunteering their services through different organizations, and medical students participating in global health electives. Much has been written about global health experiences in resource poor settings, but the literature focuses primarily on the work of health care professionals and medical students. This paper focuses on undergraduate student involvement in short term medical volunteer work in resource poor countries, a practice that has become popular among pre-health professions students. We argue that the participation of undergraduate students in global health experiences raises many of the ethical concerns associated with voluntourism and global health experiences for medical students. Some of these may be exacerbated by or emerge in unique ways when undergraduates volunteer. Guidelines and curricula for medical student engagement in global health experiences have been developed. Guidelines specific to undergraduate involvement in such trips and pre-departure curricula to prepare students should be developed and such training should be required of volunteers. We propose a framework for such guidelines and curricula, argue that universities should be the primary point of delivery even when universities are not organizing the trips, and recommend that curricula should be developed in light of additional data.

Police-Related Experiences and HIV Risk Among Female Sex Workers in Andhra Pradesh, India

Research suggests experiences with police are related to human immunodeficiency virus (HIV) sexual risk among women working as sex workers. However, little is known about the links between specific police-related behaviors and HIV vulnerability. We examine whether 5 police-related experiences are associated with measures of HIV risk and violence among a sample of female sex workers (FSWs) in Andhra Pradesh, India, and consider the implications for HIV prevention. FSWs at least 18 years of age (n = 835) were recruited through respondent-driven sampling for a cross-sectional survey conducted as part of Avahan, the India AIDS Initiative. Using logistic regression models adjusted for age, age at start of sex work, and sex work venue, we assessed police-related experiences reported by FSWs in relation to HIV risk behaviors and violence. Results showed having sex with police to avoid trouble, giving gifts to police to avoid trouble, having police take condoms away, experiencing a workplace raid, and being arrested were associated with sexually transmitted infection symptoms, inconsistent condom use, acceptance of more money for sex without a condom, and experience of client violence. These findings suggest a need for interventions targeting police–FSW interactions to reduce HIV vulnerability among FSWs. PMID:22043036

Pearson, Emma; Gibson, Jonathan; Checkland, Kath

2017-01-01

Objectives This study draws on an in-depth investigation of factors that influenced the career decisions of junior doctors. Setting Junior doctors in the UK can choose to enter specialty training (ST) programmes within 2 years of becoming doctors. Their specialty choices contribute to shaping the balance of the future medical workforce, with views on general practice (GP) careers of particular interest because of current recruitment difficulties. This paper examines how experiences of medical work and perceptions about specialty training shape junior doctors’ career decisions. Participants Twenty doctors in the second year of a Foundation Training Programme in England were recruited. Purposive sampling was used to achieve a diverse sample from respondents to an online survey. Results Narrative interviewing techniques encouraged doctors to reflect on how experiences during medical school and in medical workplaces had influenced their preferences and perceptions of different specialties. They also spoke about personal aspirations, work priorities and their wider future. Junior doctors’ decisions were informed by knowledge about the requirements of ST programmes and direct observation of the pressures under which ST doctors worked. When they encountered negative attitudes towards a specialty they had intended to choose, some became defensive while others kept silent. Achievement of an acceptable work-life balance was a central objective that could override other preferences. Events linked with specific specialties influenced doctors’ attitudes towards them. For example, findings confirmed that while early, positive experiences of GP work could increase its attractiveness, negative experiences in GP settings had the opposite effect. Conclusions Junior doctors’ preferences and perceptions about medical work are influenced by multiple intrinsic and extrinsic factors and experiences. This paper highlights the importance of understanding how perceptions are formed and preferences are developed, as a basis for generating learning and working environments that nurture students and motivate their professional careers.

Goldberg, Lynette R; Brown, Gina R; Mosack, Victoria A; Fletcher, Phyllis A

2015-01-01

This study analyzed students' written reflections following their initial exposure to interprofessional teamwork in case-based problem-solving. A three-hour seminar featuring three sequenced scenarios was developed and offered 12-times over two semesters. A total of 305 students from a variety of healthcare programs worked together with standardized patients in an on-campus laboratory simulating hospital ward and rehabilitation settings. A thematic analysis of students' reflections showed that they valued the shared learning and realistic case study. However, they felt the experience would be strengthened by working in smaller, more representative teams that included students from medicine, psychology, and social work to enable more effective communication and comprehensive case discussion. While useful for future planning, the identified themes did not enable a comparative statistical analysis of what students found helpful and difficult and a re-coding of students' responses now is underway. Implications for measuring the effectiveness of future interprofessional case-based learning center on addressing the identified weaknesses, and establishing a research design that enables a comparison of pre- and post-seminar data, and the effectiveness of the IPE experience compared to profession-specific experiences.

Working memory load modulates microsaccadic rate.

2017-03-01

Microsaccades are tiny eye movements that individuals perform unconsciously during fixation. Despite that the nature and the functions of microsaccades are still lively debated, recent evidence has shown an association between these micro eye movements and higher order cognitive processes. Here, in two experiments, we specifically focused on working memory and addressed whether differential memory load could be reflected in a modulation of microsaccade dynamics. In Experiment 1, participants memorized a numerical sequence composed of either two (low-load condition) or five digits (high-load condition), appearing at fixation. The results showed a reduction in the microsaccadic rate in the high-load compared to the low-load condition. In Experiment 2, five red or green digits were always presented at fixation. Participants either memorized the color (low-load condition) or the five digits (high-load condition). Hence, visual stimuli were exactly the same in both conditions. Consistent with Experiment 1, microsaccadic rate was lower in the high-load than in the low-load condition. Overall, these findings reveal that an engagement of working memory can have an impact on microsaccadic rate, consistent with the view that microsaccade generation is pervious to top-down processes.

Face recognition: a model specific ability.

PubMed

Wilmer, Jeremy B; Germine, Laura T; Nakayama, Ken

2014-01-01

In our everyday lives, we view it as a matter of course that different people are good at different things. It can be surprising, in this context, to learn that most of what is known about cognitive ability variation across individuals concerns the broadest of all cognitive abilities; an ability referred to as general intelligence, general mental ability, or just g. In contrast, our knowledge of specific abilities, those that correlate little with g, is severely constrained. Here, we draw upon our experience investigating an exceptionally specific ability, face recognition, to make the case that many specific abilities could easily have been missed. In making this case, we derive key insights from earlier false starts in the measurement of face recognition's variation across individuals, and we highlight the convergence of factors that enabled the recent discovery that this variation is specific. We propose that the case of face recognition ability illustrates a set of tools and perspectives that could accelerate fruitful work on specific cognitive abilities. By revealing relatively independent dimensions of human ability, such work would enhance our capacity to understand the uniqueness of individual minds.

2016-01-01

The therapeutic working alliance is a vital ingredient of psychotherapy, specifically for clients diagnosed with anorexia nervosa, as progress is often slow and treatment difficult. This qualitative phenomenological study investigated the experiences of eight clients with anorexia nervosa and seven therapists who work with this population, regarding which therapist factors aided in and challenged the working alliance formation in individual psychotherapy. Data was gathered through semi-structured interviews. Some helpful therapist factors included collaboration, appropriate self-disclosure, providing a warm and safe environment, and willingness to be contacted outside of a session. Unhelpful factors included lack of attunement and objectivity and failure to individualize treatment.

Cancer is a debilitating illness that affects more than one in every three Americans at sometime in their life time regardless of their social, cultural, ethnic, religious, or economic status. A few studies in the psychotherapy literature have investigated the impact of cancer on the personal and professional lives of psychotherapists. However, such investigations are yet unknown in medical or music therapy literature. In this descriptive phenomenological study, the researcher interviewed five American music therapists who have survived cancer and also work with patients in medical hospitals or hospice settings. The purpose of this study was to fully describe their lived experience of surviving cancer and examine how the cancer experience affected their clinical work thereafter. The data was analyzed using an open coding method from grounded theory which identified four major themes: (a) personal significance; (b) relational significance; (c) musical significance and (d) professional significance. The descriptions provided by these participants of their cancer experience as patients, survivors, and cancer surviving therapists, have revealed various psychosocial and physical issues encountered, and numerous coping methods they employed, and poignantly explained how their clinical approach evolved and expanded due to the personal experience of cancer. Specific issues in relation to countertransference, self-disclosure, and ways of developing empathic approaches without having such personal experience were discussed in addition to suggestions for future research.

Protective workshops and sheltered employment settings have been instrumental in developing the work skills of people with disabilities, however there has been a void in the literature about its influence on the ability of individuals to find employment in the open labor market. The aim of the study is to explore the experiences and perceptions of people with disabilities about the development of their work skills for transitioning into the open labor market. Five individuals with various types of disabilities and two key informants participated in the study. The research study was positioned within the qualitative paradigm specifically utilizing an exploratory and descriptive research design. In order to gather data from the participants, semi structured interviews were used. Three themes emerged from the findings of the study. Theme one, designated as "Reaching a ceiling", reflected the barriers that the participants experienced regarding work skills development. Theme two, designated as "Enablers for growth within the workplace", related to the enabling factors related to development of the work skills of persons with a disability (PWD). The final theme related to the meaning that PWD associated to their worker role and was designated as "A sense of universality". The participants highlighted that they felt their coworkers in the workshops were "like family" to them and thoroughly enjoyed the work tasks and work environment, expressing specific support from their fellow workers. Through reaching their goals, engaging in their work tasks and having the sense of universality in the workplace, the workers felt that the work they participated in gave them meaning to their life. The findings of the study indicated that managers of protective workshops and sheltered employment settings should consider selecting work tasks that enable the development of skills needed in the open labour market. A work skills development system whereby PWD in these workshops could determine their own career progression is advocated.

Neuroscientists' everyday experiences of ethics: the interplay of regulatory, professional, personal and tangible ethical spheres.

The ethical issues neuroscience raises are subject to increasing attention, exemplified in the emergence of the discipline neuroethics. While the moral implications of neurotechnological developments are often discussed, less is known about how ethics intersects with everyday work in neuroscience and how scientists themselves perceive the ethics of their research. Drawing on observation and interviews with members of one UK group conducting neuroscience research at both the laboratory bench and in the clinic, this article examines what ethics meant to these researchers and delineates four specific types of ethics that shaped their day-to-day work: regulatory, professional, personal and tangible. While the first three categories are similar to those identified elsewhere in sociological work on scientific and clinical ethics, the notion of 'tangible ethics' emerged by attending to everyday practice, in which these scientists' discursive distinctions between right and wrong were sometimes challenged. The findings shed light on how ethical positions produce and are, in turn, produced by scientific practice. Informing sociological understandings of neuroscience, they also throw the category of neuroscience and its ethical specificity into question, given that members of this group did not experience their work as raising issues that were distinctly neuro-ethical. © 2013 The Authors.

Recent theoretical and empirical work has highlighted the role of domain-general, large-scale brain networks in generating emotional experiences. These networks are hypothesized to process aspects of emotional experiences that are not unique to a specific emotional category (e.g., "sadness," "happiness"), but rather that generalize across categories. In this article, we examined the dynamic interactions (i.e., changing cohesiveness) between specific domain-general networks across time while participants experienced various instances of sadness, fear, and anger. We used a novel method for probing the network connectivity dynamics between two salience networks and three amygdala-based networks. We hypothesized, and found, that the functional connectivity between these networks covaried with the intensity of different emotional experiences. Stronger connectivity between the dorsal salience network and the medial amygdala network was associated with more intense ratings of emotional experience across six different instances of the three emotion categories examined. Also, stronger connectivity between the dorsal salience network and the ventrolateral amygdala network was associated with more intense ratings of emotional experience across five out of the six different instances. Our findings demonstrate that a variety of emotional experiences are associated with dynamic interactions of domain-general neural systems.

Background Exercise is effective in improving non-specific low back pain (LBP). Certain components of physical exercise, such as the type, intensity and frequency of exercise, are likely to influence participation among working adults with non-specific LBP, but the value and relative importance of these components remain unknown. The study’s aim was to examine such specific components and their influence on individual preferences for exercise for secondary prevention of non-specific LBP among working adults. Methods In a discrete choice experiment, working individuals with non-specific LBP answered a web-based questionnaire. Each respondent was given ten pairs of hypothetical exercise programs and asked to choose one option from each pair. The choices comprised six attributes of exercise (i.e., type of training, design, intensity, frequency, proximity and incentives), each with either three or four levels. A conditional logit regression that reflected the random utility model was used to analyze the responses. Results The final study population consisted of 112 participants. The participants’ preferred exercise option was aerobic (i.e., cardiovascular) rather than strength training, group exercise with trainer supervision, rather than individual or unsupervised exercise. They also preferred high intensity exercise performed at least once or twice per week. The most popular types of incentive were exercise during working hours and a wellness allowance rather than coupons for sports goods. The results show that the relative value of some attribute levels differed between young adults (age ≤ 44 years) and older adults (age ≥ 45 years) in terms of the level of trainer supervision required, exercise intensity, travel time to exercise location and financial incentives. For active study participants, exercise frequency (i.e., twice per week, 1.15; CI: 0.25; 2.06) influenced choice of exercise. For individuals with more than one child, travel time (i.e., 20 minutes, -0.55; CI: 0.65; 3.26) was also an influential attribute for choice of exercise, showing that people with children at home preferred to exercise close to home. Conclusions This study adds to our knowledge about what types of exercise working adults with back pain are most likely to participate in. The exercise should be a cardiovascular type of training carried out in a group with trainer supervision. It should also be of high intensity and preferably performed twice per week during working hours. Coupons for sports goods do not appear to motivate physical activity among workers with LBP. The findings of the study could have a substantial impact on the planning and development of exercise provision and promotion strategies to improve non-specific LBP. Providers and employers may be able to improve participation in exercise programs for adults with non-specific LBP by focusing on the exercise components which are the most attractive. This in turn would improve satisfaction and adherence to exercise interventions aimed at preventing recurrent non-specific LBP. PMID:29244841

2018-12-01

Work is undoubtedly fundamental to human life, social development and the economic development of individuals, organizations and nations. However, the experience of working is not always pleasant as there are many instances where relationships between workers could deteriorate, leading to practices and behaviours that could be characterized as workplace bullying and/or mobbing. The current study is an exploratory study which used autoethnography to investigate experiences of academic bullying and mobbing, and relates the practices to power structures in academic institutions. Specifically, the author shares personal experiences and explores the physical and emotional pain of being bullied and mobbed. The author also outlines how both autoethnography and meaning in life strategies were used to cope with the physical and emotional distresses associated with the negative experiences. By outlining the success of the meaning in life strategies, the author hopes to inspire other "victims" to move from victims to being survivors of bullying and mobbing.

The odd-even effect in Sudoku puzzles: effects of working memory, aging, and experience.

PubMed

Chang, Hye-Sang; Gibson, Janet M

2011-01-01

The odd-even effect in numerical processing has been explained as the easier processing of even numbers compared with odd numbers. We investigated this effect in Sudoku puzzles, a reasoning problem that uses numbers but does not require arithmetic operations. Specifically, we asked whether the odd-even effect occurred with Sudoku puzzles and whether individual differences in working memory (WM), aging, and experience with Sudoku modulated this effect. We manipulated the presence of odd and even numbers in Sudoku puzzles, measured WM with the Wisconsin Card Sorting Test and backward digit span task, tested older and younger adults, and collected Sudoku experience frequency. Performance on Sudoku was more accurate for even puzzles than odd ones. Younger, experienced, and higher-WM participants were more accurate on Sudoku, but these individual difference variables did not interact with the odd-even effect. Odd numbers may impose more cognitive load than even numbers, but future research is needed to examine how age, experience, or WM may influence the odd-even effect.

A study on electrical and mechanical (E&M) works-related accidents for public sector projects provided the opportunity to gain a better understanding of the causes of accidents by analyzing the circumstances of all E&M works accidents. The research aims to examine accidents of E&M works which happened in public sector projects. A total of 421 E&M works-related accidents in the "Public Works Programme Construction Site Safety and Environmental Statistics" (PCSES) system were extracted for analysis. Two-step cluster analysis was conducted to classify the E&M accidents into different groups. The results identified three E&M accidents groups: (1) electricians with over 15 years of experience were prone to 'fall of person from height'; (2) electricians with zero to five years of experience were prone to 'slip, trip or fall on same level'; (3) air-conditioning workers with zero to five years of experience were prone to multiple types of accidents. Practical measures were recommended for each specific cluster group to avoid recurrence of similar accidents. The accident analysis would be vital for industry practitioners to enhance the safety performance of public sector projects. This study contributes to filling the knowledge gap of how and why E&M accidents occur and promulgating preventive measures for E&M accidents which have been under researched.

2014-01-01

Since 2010, French companies must integrate or retain seniors to avoid a fine of 1% of their payroll. This work examines how to integrate the aging of employees into occupational health policies. The literature on the complex relationships between age, work and health has been reviewed, and the feasibility of potential actions has been addressed. In the company setting, few diseases are specific to seniors. With retirement age postponing, chronic diseases may appear more frequently in people still working. Physiological aging linked to a functional decline is variable. Occupational wear and tear can result in some functional deterioration. Seniors can experience difficulties coping with heavy time demands that restrict their ability to organize the work, with physical stresses due to their diminished muscular capacity, and with unconventional schedules that have long-term deleterious effects on sleep quality and alertness. This position paper makes recommendations for adapting work organization and occupational medical care. Protective measures for seniors should be integrated in a global approach to improving work conditions for all. Aging employees need some leeway to develop experience-based strategies for bypassing new difficulties. Revising work rhythms and developing autonomy seem to be means for progress.

What works with worked examples: Extending self-explanation and analogical comparison to synthesis problems

2017-12-01

The ability to solve physics problems that require multiple concepts from across the physics curriculum—"synthesis" problems—is often a goal of physics instruction. Three experiments were designed to evaluate the effectiveness of two instructional methods employing worked examples on student performance with synthesis problems; these instructional techniques, analogical comparison and self-explanation, have previously been studied primarily in the context of single-concept problems. Across three experiments with students from introductory calculus-based physics courses, both self-explanation and certain kinds of analogical comparison of worked examples significantly improved student performance on a target synthesis problem, with distinct improvements in recognition of the relevant concepts. More specifically, analogical comparison significantly improved student performance when the comparisons were invoked between worked synthesis examples. In contrast, similar comparisons between corresponding pairs of worked single-concept examples did not significantly improve performance. On a more complicated synthesis problem, self-explanation was significantly more effective than analogical comparison, potentially due to differences in how successfully students encoded the full structure of the worked examples. Finally, we find that the two techniques can be combined for additional benefit, with the trade-off of slightly more time on task.

Intersections of Stigma, Mental Health, and Sex Work: How Canadian Men Engaged in Sex Work Navigate and Resist Stigma to Protect Their Mental Health.

2018-05-01

Men engaged in sex work experience significant stigma that can have devastating effects for their mental health. Little is known about how male sex workers experience stigma and its effects on mental health or their strategies to prevent its effects in the Canadian context. This study examined the interrelationships between stigma and mental health among 33 Canadian indoor, male sex workers with a specific goal of understanding how stigma affected men's mental health and their protective strategies to mitigate against its effects. Men experienced significant enacted stigma that negatively affected their social supports and ability to develop and maintain noncommercial, romantic relationships. Men navigated stigma by avoidance and resisting internalization. Strategy effectiveness to promote mental health varied based on men's perspectives of sex work as a career versus a forced source of income. Programming to promote men's mental health must take into consideration men's diverse strategies and serve to build social supports.

Object formation in visual working memory: Evidence from object-based attention.

PubMed

Zhou, Jifan; Zhang, Haihang; Ding, Xiaowei; Shui, Rende; Shen, Mowei

2016-09-01

We report on how visual working memory (VWM) forms intact perceptual representations of visual objects using sub-object elements. Specifically, when objects were divided into fragments and sequentially encoded into VWM, the fragments were involuntarily integrated into objects in VWM, as evidenced by the occurrence of both positive and negative object-based attention effects: In Experiment 1, when subjects' attention was cued to a location occupied by the VWM object, the target presented at the location of that object was perceived as occurring earlier than that presented at the location of a different object. In Experiment 2, responses to a target were significantly slower when a distractor was presented at the same location as the cued object (Experiment 2). These results suggest that object fragments can be integrated into objects within VWM in a manner similar to that of visual perception. Copyright © 2016 Elsevier B.V. All rights reserved.

Moral principles or consumer preferences? Alternative framings of the trolley problem.

PubMed

Rai, Tage S; Holyoak, Keith J

2010-03-01

We created paired moral dilemmas with minimal contrasts in wording, a research strategy that has been advocated as a way to empirically establish principles operative in a domain-specific moral psychology. However, the candidate "principles" we tested were not derived from work in moral philosophy, but rather from work in the areas of consumer choice and risk perception. Participants were paradoxically less likely to choose an action that sacrifices one life to save others when they were asked to provide more reasons for doing so (Experiment 1), and their willingness to sacrifice lives depended not only on how many lives would be saved, but on the number of lives at risk (Experiment 2). The latter effect was also found in a within-subjects design (Experiment 3). These findings suggest caution in the use of artificial dilemmas as a key testbed for revealing principled bases for moral judgment. Copyright © 2009 Cognitive Science Society, Inc.

Navier-Stokes simulation of the crossflow instability in swept-wing flows

NASA Technical Reports Server (NTRS)

Reed, Helen L.

1989-01-01

The computational modeling of the transition process characteristic of flows over swept wings are described. Specifically, the crossflow instability and crossflow/T-S wave interactions are analyzed through the numerical solution of the full three-dimensional Navier-Stokes equations including unsteadiness, curvature, and sweep. This approach is chosen because of the complexity of the problem and because it appears that linear stability theory is insufficient to explain the discrepancies between different experiments and between theory and experiments. The leading edge region of a swept wing is considered in a three-dimensional spatial simulation with random disturbances as the initial conditions. The work has been closely coordinated with the experimental program of Professor William Saric, examining the same problem. Comparisons with NASA flight test data and the experiments at Arizona State University were a necessary and an important integral part of this work.

SUPPORTING PRETERM INFANT ATTACHMENT AND SOCIOEMOTIONAL DEVELOPMENT IN THE NEONATAL INTENSIVE CARE UNIT: STAFF PERCEPTIONS.

The infant-parent relationship has been shown to be of particular significance to preterm infant socioemotional development. Supporting parents and infants in this process of developing their relationships is an integral part of neonatal intensive care; however, there is limited knowledge of NICU staff perceptions about this aspect of care. To explore NICU staff perceptions about attachment and socioemotional development of preterm infants, experience of training in this area and the emotional impact of their work. A cross-sectional questionnaire survey of staff perceptions of the emotional experiences of parents and the developing parent-infant relationship in an NICU was conducted in a Level III NICU, after pilot testing, revision, and ethical approval. Fifty-seven (68%) of NICU staff responded to the survey. Respondents identified parents' emotional experiences such as "anxiety," "shock," "loss of control," and "lack of feelings of competence as parents" as highly prevalent. Infant cues of "responding to parent's voice" and "quieting-alerting" were ranked most highly; "crying" and "physiological changes" were ranked lowest. Preterm infant medical risk, maternal emotional state, and mental health are perceived to impact most highly on the developing relationship, as compared with infant state or behavior and socioeconomic factors. Fifty-three (93%) respondents felt confident, and 50 (87.8%) felt competent discussing their emotional experiences with parents. Fifty-four (95%) responded that attending to these areas was an integral part of their role; however, staff had seldom received education in this area. Respondents also perceived that specific psychological support for parents was lacking both during and after the infant's discharge. While all staff surveyed perceived the nature of their work to be emotionally stressful, there were differences among NICU staff disciplines and with years of experience in the NICU in terms of their perceptions about education in this area, the place of supervision for staff, and in relation to opportunities to discuss the emotional impact of the work on staff. NICU staff perceive their role as integral to supporting the developing parent-infant relationship and preterm infant socioemotional development; however, education in this area and provision of specific psychological support are lacking. Opportunities for staff to discuss and reflect on this aspect of their work should be developed and evaluated given the essential, but emotionally challenging, nature of their work with preterm babies and their parents. © 2016 Michigan Association for Infant Mental Health.

Mother's home healthcare: emotion work when a child has cancer.

Clarke, Juanne N

2006-01-01

Home healthcare work, involving physical labor, nursing care, medical monitoring, administrative, planning and accounting, advocacy and emotion work, is unpaid and largely invisible. This article, based on focus group interviews with mothers whose children have had cancer, describes one part of their home healthcare labor, their emotion work. Specifically, it examines how mothers: manage the moral imperatives of mothering; think about and try to manage the strong feelings, particularly of fear and uncertainty that they often have when their children are ill with cancer; work to understand and maintain their marital relationships; the strategies that seemed to help; and finally, the self-transformation that many mothers experience. The article concludes with a discussion of the substantive, theoretical, research, and policy implications of emotion work in the provision of home healthcare work.

The Box Task: A tool to design experiments for assessing visuospatial working memory.

PubMed

Kessels, Roy P C; Postma, Albert

2017-09-15

The present paper describes the Box Task, a paradigm for the computerized assessment of visuospatial working memory. In this task, hidden objects have to be searched by opening closed boxes that are shown at different locations on the computer screen. The set size (i.e., number of boxes that must be searched) can be varied and different error scores can be computed that measure specific working memory processes (i.e., the number of within-search and between-search errors). The Box Task also has a developer's mode in which new stimulus displays can be designed for use in tailored experiments. The Box Task comes with a standard set of stimulus displays (including practice trials, as well as stimulus displays with 4, 6, and 8 boxes). The raw data can be analyzed easily and the results of individual participants can be aggregated into one spreadsheet for further statistical analyses.

An internal variable constitutive model for the large deformation of metals at high temperatures

NASA Technical Reports Server (NTRS)

Brown, Stuart; Anand, Lallit

1988-01-01

The advent of large deformation finite element methodologies is beginning to permit the numerical simulation of hot working processes whose design until recently has been based on prior industrial experience. Proper application of such finite element techniques requires realistic constitutive equations which more accurately model material behavior during hot working. A simple constitutive model for hot working is the single scalar internal variable model for isotropic thermal elastoplasticity proposed by Anand. The model is recalled and the specific scalar functions, for the equivalent plastic strain rate and the evolution equation for the internal variable, presented are slight modifications of those proposed by Anand. The modified functions are better able to represent high temperature material behavior. The monotonic constant true strain rate and strain rate jump compression experiments on a 2 percent silicon iron is briefly described. The model is implemented in the general purpose finite element program ABAQUS.

Medical educators working abroad: a pilot study of educators' experiences in the Middle East.

Medical education is now a global enterprise, with many medical educators working internationally, either for short or longer periods or even permanently. In parallel, many medical schools are now involved in collaborations and partnerships with schools in other countries. With this in mind, we set out to explore what motivates, supports and inhibits medical educators who wish to or might work outside their "home country". This article reports on the pilot stage (in specific organizational contexts in Middle East) of a longitudinal project aimed at canvassing medical educators on a broader global scale, using reflective accounts and a questionnaire survey. The findings from this pilot study raise interesting issues about the lived experience of medical educators who have chosen to work in a different culture from their own. Respondents identify many advantages around skills, personal and professional development. Three main issues emerged in terms of educators' experiences: the academic environment, medical practice in a different cultural context and personal matters. Adapting to the local culture, gender segregation and the impact on learning and teaching was an overarching factor. We introduce an explanatory framework to explain the development of international educator identity, a cyclical process in which, through experiences and reflection, individual world views and perspectives are continually modified and developed. This pilot study tested the methodologies and developed a new conceptual model that will be used in a wider study across different cultures.

Heuer, H.; Spijkers, W.; Kiesswetter, E.; Schmidtke, V.

1998-01-01

Tacit knowledge is part of many professional skills and can be studied experimentally with implicit-learning paradigms. The authors explored the effects of 2 different stressors, loss of sleep and mental fatigue, on implicit learning in a serial-response time (RT) task. In the 1st experiment, 1 night of sleep deprivation was shown to impair implicit but not explicit sequence learning. In the 2nd experiment, no impairment of both types of sequence learning was found after 1.5 hr of mental work. Serial-RT performance, in contrast, suffered from both stressors. These findings suggest that sleep deprivation induces specific risks for automatic, skill-based behavior that are not present in consciously controlled performance.

2011-07-01

Consultation is integral to maintaining competence for health professionals and involves a collaborative relationship between specialist and primary care services. Although consultation aims to support them in their work, existing literature exploring health visitors' experiences of consultation is limited. This study explored health visitors' experiences of consultation in relation to their clinical practice, their experience of their work and its impact on the wider service. In all, 10 health visitors were interviewed using a semi-structured guide and analysis was subjected to a grounded theory framework. Participants' views were influenced by a combination of factors--consultants' training specific to their role, their communication and engagement, consultation's support of joint-working and/or transitions, and its relevance to and impact upon practice. Findings suggest that such interface activities require effective co-ordination, communication and structuring strategies, highlighting the importance of future initiatives in developing health visitors' mental health role further. Given the comparative lack of evaluation of such activities, these findings may inform policy-making and service development to ensure high quality of service delivery.

Daily stressors, war experiences, and mental health in Afghanistan.

2008-12-01

Working in Afghanistan's capital city of Kabul, the authors assessed the relative contribution of daily stressors and war-related experiences of violence and loss to levels of depression, PTSD, impaired functioning, and a culturally specific measure of general psychological distress. For women, daily stressors were a better predictor than war experiences of all mental health outcomes except for PTSD; for men, daily stressors were a better predictor of depression and functional impairment, while war experiences and daily stressors were similarly predictive of general distress. For men, daily stressors moderated the relationship between war experiences and PTSD, which was significant only under conditions of low daily stress. The study's implications for research and intervention in conflict and post-conflict settings are considered.

Context-dependent control of attention capture: Evidence from proportion congruent effects.

2018-06-01

There are several independent demonstrations that attentional phenomena can be controlled in a context-dependent manner by cues associated with differing attentional control demands. The present set of experiments provide converging evidence that attention-capture phenomena can be modulated in a context-dependent fashion. We determined whether methods from the proportion congruent literature (listwide and item- and context-specific proportion congruent designs) that are known to modulate distractor interference effects in Stroop and flanker tasks are capable of modulating attention capture by salient feature singletons. Across experiments we found evidence that attention capture can be modulated by listwide, item-specific, and context-specific manipulations of proportion congruent. We discuss challenges associated with interpreting results from proportion congruent studies but propose that our findings converge with existing work that has demonstrated context-dependent control of attention capture.

Overhearers Use Addressee Backchannels in Dialog Comprehension.

PubMed

Tolins, Jackson; Fox Tree, Jean E

2016-08-01

Observing others in conversation is a common format for comprehending language, yet little work has been done to understand dialog comprehension. We tested whether overhearers use addressee backchannels as predictive cues for how to integrate information across speaker turns during comprehension of spontaneously produced collaborative narration. In Experiment 1, words that followed specific backchannels (e.g., really, oh) were recognized more slowly than words that followed either generic backchannels (e.g., uh huh, mhm) or pauses. In Experiment 2, we found that when the turn after the backchannel was a continuation of the narrative, specific backchannels prompted the fastest verification of prior information. When the turn after was an elaboration, they prompted the slowest, indicating that overhearers took specific backchannels as cues to integrate preceding talk with subsequent talk. These findings demonstrate that overhearers capitalize on the predictive relationship between backchannels and the development of speakers' talk, coordinating information across conversational roles.

Remembering faces and scenes: The mixed-category advantage in visual working memory.

PubMed

Jiang, Yuhong V; Remington, Roger W; Asaad, Anthony; Lee, Hyejin J; Mikkalson, Taylor C

2016-09-01

We examined the mixed-category memory advantage for faces and scenes to determine how domain-specific cortical resources constrain visual working memory. Consistent with previous findings, visual working memory for a display of 2 faces and 2 scenes was better than that for a display of 4 faces or 4 scenes. This pattern was unaffected by manipulations of encoding duration. However, the mixed-category advantage was carried solely by faces: Memory for scenes was not better when scenes were encoded with faces rather than with other scenes. The asymmetry between faces and scenes was found when items were presented simultaneously or sequentially, centrally, or peripherally, and when scenes were drawn from a narrow category. A further experiment showed a mixed-category advantage in memory for faces and bodies, but not in memory for scenes and objects. The results suggest that unique category-specific interactions contribute significantly to the mixed-category advantage in visual working memory.

Increasing research has evidenced that our brain retains a capacity to change in response to experience until late adulthood. This implies that cognitive training can possibly ameliorate age-associated cognitive decline by inducing training-specific neural plastic changes at both neural and behavioral levels. This longitudinal study examined the behavioral effects of a systematic thirteen-week cognitive training program on attention and working memory of older adults who were at risk of cognitive decline. These older adults were randomly assigned to the Cognitive Training Group (n = 109) and the Active Control Group (n = 100). Findings clearly indicated that training induced improvement in auditory and visual-spatial attention and working memory. The training effect was specific to the experience provided because no significant difference in verbal and visual-spatial memory between the two groups was observed. This pattern of findings is consistent with the prediction and the principle of experience-dependent neuroplasticity. Findings of our study provided further support to the notion that the neural plastic potential continues until older age. The baseline cognitive status did not correlate with pre- versus posttraining changes to any cognitive variables studied, suggesting that the initial cognitive status may not limit the neuroplastic potential of the brain at an old age.

2018-05-25

The lived experience of licensed practical nurses (LPNs) pursuing Bachelor of Nursing (BN) education is not commonly studied in Canada. The aim was to understand the transition experience of LPNs who bridged into a BN program. Max van Manen's phenomenological methodology was used through use of a semistructured interview guide to explore the lived experience of LPNs who pursued baccalaureate nursing education. Five themes were found: seeking advancement; stepping back into the student role; juggling work, school, and family; struggling to be understood; and seeing things differently. LPN-to-BN students have a well-developed sense of identity as nurses. These students can benefit from a specifically designed, stand-alone bridge course to situate them within a BN program.

This work consisted of the following major efforts; 1. Literature survey on validation of external natural convection; 2. Design the experiment; 3. Build the experiment; 4. Run the experiment; 5. Collect results; 6. Disseminate results; and 7. Perform a CFD validation study using the results. We note that while all tasks are complete, some deviations from the original plan were made. Specifically, geometrical changes in the parameter space were skipped in favor of flow condition changes, which were found to be much more practical to implement. Changing the geometry required new as-built measurements, which proved extremely costly and impractical givenmore » the time and funds available« less

Getting what you want: How fit between desired and received leader sensitivity influences emotion and counterproductive work behavior.

Rupprecht, Elizabeth A; Kueny, Clair Reynolds; Shoss, Mindy K; Metzger, Andrew J

We challenge the intuitive belief that greater leader sensitivity is always associated with desirable outcomes for employees and organizations. Specifically, we argue that followers' idiosyncratic desires for, and perceptions of, leader sensitivity behaviors play a key role in how followers react to their leader's sensitivity. Moreover, these resulting affective experiences are likely to have important consequences for organizations, specifically as they relate to employee counterproductive work behavior (CWB). Drawing from supplies-values (S-V) fit theory and the stressor-emotion model of CWB, the current study focuses on the affective and behavioral consequences of fit between subordinates' ideal leader sensitivity behavior preferences and subordinates' perceptions of their actual leader's sensitivity behaviors. Polynomial regression analyses reveal that congruence between ideal and actual leader sensitivity influences employee negative affect and, consequently, engagement in counterproductive work behavior.

Motivation, working memory, and decision making: a cognitive-motivational theory of personality vulnerability to alcoholism.

PubMed

Finn, Peter R

2002-09-01

This article presents a cognitive-motivational theory (CMT) of the mechanisms associated with three basic dimensions of personality vulnerability to alcoholism, impulsivity/novelty seeking, harm avoidance, and excitement seeking. CMT describes the interrelationships between activity in basic motivational systems and attentional, decision-making and working memory processes as the mechanisms associated with variation in each personality trait. Impulsivity/novelty seeking reflects activity in both appetitive and inhibitory motivational systems, greater attention to reward cues, and increased emotional reactivity to reward and frustration. Harm avoidance reflects individual differences in fearfulness and activity in specific inhibitory systems. Excitement seeking reflects the need to engage in appetitive behaviors in less predictable environments to experience positive affect. CMT also describes the impact of working memory and the specific motivational processes underlying each trait dimension on the dynamics of decision making from the perspective of decision field theory.

Exploiting epoxidized natural rubber latex (ENRL) as a starting raw material for latex-based products

NASA Astrophysics Data System (ADS)

Siti Nor Qamarina, M.; Fatimah Rubaizah, M. R.; Nurul Suhaira, A.; Norhanifah, M. Y.

Epoxidized natural rubber latex (ENRL) is a chemically modified natural rubber latex produced from epoxidation process that involves usage of organic peracids. Conversion of the ENRL into dry rubber products has been known to exhibit many beneficial properties, however limited published works were found on diversifiying the ENRL latex-based products applications. In this preliminary work, different source of raw materials and neutralization systems were investigated. The objective was to explore possibilities in producing distinctive ENRL. Findings have demonstrated that different source of raw materials and neutralization systems influenced the typical ENRL specifications, stability behavior and particle size distribution. Morphological observations performed on these ENRL systems appeared to agree with the ENRL characteristics achieved. Since experimenting these two main factors resulted in encouraging ENRL findings, detailed work shall be further scrutinized to search for an optimum condition in producing marketable ENRL specifically for latex-based products applications.

In the working memory of the beholder: Art appreciation is enhanced when visual complexity is compatible with working memory.

Sherman, Aleksandra; Grabowecky, Marcia; Suzuki, Satoru

2015-08-01

What shapes art appreciation? Much research has focused on the importance of visual features themselves (e.g., symmetry, natural scene statistics) and of the viewer's experience and expertise with specific artworks. However, even after taking these factors into account, there are considerable individual differences in art preferences. Our new result suggests that art preference is also influenced by the compatibility between visual properties and the characteristics of the viewer's visual system. Specifically, we have demonstrated, using 120 artworks from diverse periods, cultures, genres, and styles, that art appreciation is increased when the level of visual complexity within an artwork is compatible with the viewer's visual working memory capacity. The result highlights the importance of the interaction between visual features and the beholder's general visual capacity in shaping art appreciation. (c) 2015 APA, all rights reserved).

Increasing the racial and ethnic diversity of the physician workforce is a national priority. However, insight into the professional experiences of minority physicians is limited. This knowledge is fundamental to developing effective strategies to recruit, retain, and support a diverse physician workforce. To characterize how physicians of African descent experience race in the workplace. Qualitative study based on in-person and in-depth racially concordant interviews using a standard discussion guide. The 6 New England states in the United States. 25 practicing physicians of African descent representing a diverse range of primary practice settings, specialties, and ages. Professional experiences of physicians of African descent. 1) Awareness of race permeates the experience of physicians of African descent in the health care workplace; 2) race-related experiences shape interpersonal interactions and define the institutional climate; 3) responses to perceived racism at work vary along a spectrum from minimization to confrontation; 4) the health care workplace is often silent on issues of race; and 5) collective race-related experiences can result in "racial fatigue," with personal and professional consequences for physicians. The study was restricted to New England and may not reflect the experiences of physicians in other geographic regions. The findings are meant to be hypothesis-generating and require additional follow-up studies. The issue of race remains a pervasive influence in the work lives of physicians of African descent. Without sufficient attention to the specific ways in which race shapes physicians' work experiences, health care organizations are unlikely to create environments that successfully foster and sustain a diverse physician workforce.

Modality independence of order coding in working memory: Evidence from cross-modal order interference at recall.

PubMed

Vandierendonck, André

2016-01-01

Working memory researchers do not agree on whether order in serial recall is encoded by dedicated modality-specific systems or by a more general modality-independent system. Although previous research supports the existence of autonomous modality-specific systems, it has been shown that serial recognition memory is prone to cross-modal order interference by concurrent tasks. The present study used a serial recall task, which was performed in a single-task condition and in a dual-task condition with an embedded memory task in the retention interval. The modality of the serial task was either verbal or visuospatial, and the embedded tasks were in the other modality and required either serial or item recall. Care was taken to avoid modality overlaps during presentation and recall. In Experiment 1, visuospatial but not verbal serial recall was more impaired when the embedded task was an order than when it was an item task. Using a more difficult verbal serial recall task, verbal serial recall was also more impaired by another order recall task in Experiment 2. These findings are consistent with the hypothesis of modality-independent order coding. The implications for views on short-term recall and the multicomponent view of working memory are discussed.

There is consensus that plant species richness enhances plant productivity within natural grasslands, but the underlying drivers remain debated. Recently, differential accumulation of soil-borne fungal pathogens across the plant diversity gradient has been proposed as a cause of this pattern. However, the below-ground environment has generally been treated as a 'black box' in biodiversity experiments, leaving these fungi unidentified. Using next generation sequencing and pathogenicity assays, we analysed the community composition of root-associated fungi from a biodiversity experiment to examine if evidence exists for host specificity and negative density dependence in the interplay between soil-borne fungi, plant diversity and productivity. Plant species were colonised by distinct (pathogenic) fungal communities and isolated fungal species showed negative, species-specific effects on plant growth. Moreover, 57% of the pathogenic fungal operational taxonomic units (OTUs) recorded in plant monocultures were not detected in eight plant species plots, suggesting a loss of pathogenic OTUs with plant diversity. Our work provides strong evidence for host specificity and negative density-dependent effects of root-associated fungi on plant species in grasslands. Our work substantiates the hypothesis that fungal root pathogens are an important driver of biodiversity-ecosystem functioning relationships. © 2018 The Authors.

Subthalamic nucleus deep brain stimulation affects distractor interference in auditory working memory.

PubMed

Camalier, Corrie R; Wang, Alice Y; McIntosh, Lindsey G; Park, Sohee; Neimat, Joseph S

2017-03-01

Computational and theoretical accounts hypothesize the basal ganglia play a supramodal "gating" role in the maintenance of working memory representations, especially in preservation from distractor interference. There are currently two major limitations to this account. The first is that supporting experiments have focused exclusively on the visuospatial domain, leaving questions as to whether such "gating" is domain-specific. The second is that current evidence relies on correlational measures, as it is extremely difficult to causally and reversibly manipulate subcortical structures in humans. To address these shortcomings, we examined non-spatial, auditory working memory performance during reversible modulation of the basal ganglia, an approach afforded by deep brain stimulation of the subthalamic nucleus. We found that subthalamic nucleus stimulation impaired auditory working memory performance, specifically in the group tested in the presence of distractors, even though the distractors were predictable and completely irrelevant to the encoding of the task stimuli. This study provides key causal evidence that the basal ganglia act as a supramodal filter in working memory processes, further adding to our growing understanding of their role in cognition.

Methods to recognize work-related cancer in workplaces, the general population, and by experts in the clinic, a Norwegian experience

PubMed Central

2011-01-01

Background In most countries, the numbers of work-related cancer identified are much lower than are the estimated total burden of cancer caused by exposure at work. Therefore, there is a great need to use all available practical as well as epidemiological methods for identification as well as to develop new methods of recognizing cases of work-related cancers. Methods Primarily based on practical experiences from Norway, methods to identify cases of possible work-related cancers in the general population and at workplaces as well as methods to recognize more specific cases after referral to specialized clinics are reviewed in this publication. Results Countries applying a number of the available methods to detect work-related cancer reach a reporting rate of 60 such cases per million, while other countries that do not employ such methods hardly identify any cases. As most subjects previously exposed to cancer causing agents and substances at work are gradually recruited out of work, methods should be versatile for identification of cases in the general population, as well as at work. Conclusions Even in countries using a number of the available methods for identification, only a limited fraction of the real number of work-related cancer are notified to the labour inspectorate. Clinicians should be familiar with the methods and do the best to identify work-related cancer to serve prevention. PMID:21899752

A Survey of Occupational Therapy Practice in Beijing, China.

Shi, Yun; Howe, Tsu-Hsin

2016-06-01

There is an increasing demand for rehabilitation services in China as a result of the growing number of people with physical and mental challenges, as well as the growing population of older adults. The purpose of this study was to explore the current occupational therapy (OT) resources available in Beijing, China, to serve as the first step in planning the response to increasing demand for OT services from the people of China. Specifically, using the snowball sampling survey method, we explored the work practice, including years of working experience, work setting, weekly work hours, annual income and factors related to job satisfaction among occupational therapists in Beijing, China. A total of 44 occupational therapists currently working in the Beijing area responded to our survey. The results demonstrated that most of the therapists working in Beijing area were young and inexperienced. Despite the fact that the participants had an average age of 31 years old and an average of 8 years' working experience, 61.4% of therapists were under 30 years old and more than half of therapists had less than 5 years of OT experiences. Among those included in the study sample, 50% had earned degrees in OT, and the rest of the OT personnel received OT-related on-the-job training in various forms and lengths of time. A majority of the participants worked in hospital settings with adults or children with physical disabilities and used therapeutic activities and therapeutic exercises. Being an occupational therapist is not a high-paying job. Education satisfaction, work experience and annual income are the factors related to job satisfaction for the participants. The majority of occupational therapists expressed the need to receive more support for clinical-related trainings. We plan to expand this pilot study nationwide to gain an in-depth and comprehensive understanding of the OT workforce in China. Copyright © 2016 John Wiley & Sons, Ltd.

Pre-exposure to cocaine or morphine attenuates taste avoidance conditioning in adolescent rats: Drug specificity in the US pre-exposure effect.

PubMed

Clasen, Matthew M; Hempel, Briana J; Riley, Anthony L

2017-05-01

Although the attenuating effects of drug history on conditioned taste avoidance (CTA) learning have been widely investigated in adults, such effects in adolescents have not been well characterized. Recent research has suggested that the display of the drug pre-exposure effect during adolescence may be drug dependent given that pre-exposure to ethanol attenuates subsequent conditioning, whereas pre-exposure to the classic emetic lithium chloride (LiCl) fails to do so. The present study began investigating the possible drug-dependent nature of the effects of drug pre-exposure by pre-exposing and conditioning adolescent male Sprague-Dawley rats to drugs from two additional classes, specifically psychostimulants (cocaine; Experiment 1) and opioids (morphine; Experiment 2). Consistent with prior work with ethanol (but not LiCl), prior exposure to both cocaine and morphine attenuated taste avoidance induced by these compounds. Although this work supports the view of drug-dependent pre-exposure effects on taste avoidance learning during adolescence, research is needed to assess its mechanisms. © 2017 Wiley Periodicals, Inc.

Returning to work - a long-term process reaching beyond the time frames of multimodal non-specific back pain rehabilitation.

Hellman, Therese; Jensen, Irene; Bergström, Gunnar; Busch, Hillevi

2015-01-01

To explore and describe health professionals' experience of working with return to work (RTW) in multimodal rehabilitation for people with non-specific back pain. An interview study using qualitative content analysis. Fifteen participants were interviewed, all were working with multimodal rehabilitation for people with non-specific back pain in eight different rehabilitation units. The participants experienced RTW as a long-term process reaching beyond the time frames of the multimodal rehabilitation (MMR). Their attitudes and, their patients' condition, impacted on their work which focused on psychological and physical well-being as well as participation in everyday life. They often created an action plan for the RTW process, however the responsibility for its realisation was transferred to other actors. The participants described limited interventions in connection with patients' workplaces. Recommended support in the RTW process in MMR comprises the provision of continuous supervision of vocational issues for the health care professionals, the development of guidelines and a checklist for how to work in close collaboration with patients' workplaces and employers, the provision of long-term follow-up in relation to the patients' work, and the development of proper interventions in order to promote transitions between all the different actors involved. Rehabilitation programs targeting return to work (RTW) for people with non-specific back pain needs to include features concretely focusing on vocational issues. Health and RTW is often seen as a linear process in which health comes before RTW. Rehabilitation programs could be tailored to better address the reciprocal relationship between health and work, in which they are interconnected and affect each other. The RTW process is reaching beyond the time frames of the multimodal rehabilitation but further support from the patients are asked for. The rehabilitation programs needs to be designed to provide long-term follow-up in relation to the patients' work.

Effect of work during pregnancy.

PubMed

Chamberlain, G

1985-05-01

Obstetricians pay much attention to the diet and environment of the pregnant woman in prenatal care, but perhaps the woman's work also may affect pregnancy outcome. All women work in the home in addition to any work performed outside the home. The former component needs careful assessment; to get from home to work may be itself a stressful experience. In the workplace, women may encounter specific hazards of radiation or chemicals. More widespread are the problems of fatigue and boredom, which need careful assessment in relation to the outcome of pregnancy. These factors should be measured more precisely, thus allowing the physician to advise pregnant women better about the safe duration of work. Currently, advice tends to be overly cautious, as physicians are uncertain of the data on which such standards are based.

The IGS network infrastructure, in large part originally commissioned for geodynamical investigations, has proved to be a valuable asset in developing application-oriented subnetworks whose requirements overlap the characteristics of existing IGS stations and future station upgrades. Issues encountered thus far in the development of multipurpose or multitechnique IGS projects as well as future possibilities will be reviewed.

Many post-secondary institutions provide training and resources to help GTAs fulfil their teaching roles. However, few programmes focus specifically on the teaching competencies required by GTAs who work with undergraduate students in laboratory settings where learning tends to be more active and inquiry based than in classroom settings. From a review of 8 GTA manuals, we identified 20 competencies and then surveyed faculty and lab coordinators (FIS) and GTAs from a Faculty of Science at a comprehensive Canadian university to identify which of those competencies are required of GTAs who work in undergraduate science labs. GTAs and FIS did not significantly differ in the competencies they view as required for GTAs to work effectively in undergraduate labs. But, when comparing the responses of GTAs and FIS to TA manuals, 'Clearly and effectively communicates ideas and information with students' was the only competency for which there was agreement on the level of requirement. We also examined GTAs' self-efficacy for each of the identified competencies and found no overall relationship between self-efficacy and demographic characteristics, including experience and training. Our results can be used to inform the design of training programmes specifically for GTAs who work in undergraduate science labs, for example, programmes should provide strategies for GTAs to obtain feedback which they can use to enhance their teaching skills. The goal of this study is to improve undergraduate lab instruction in faculties of science and to enhance the teaching experience of GTAs by better preparing them for their role.

The consumption of soft-drinks has been associated with dental caries development. The aim was to evaluate dental caries experience amongst the workers working in soft-drink industries located in South India and compare it with other factory workers. To evaluate the validity of specific caries index (SCI), which is newer index for caries diagnosis. This was a cross-sectional study carried out among 420 workers (210 in soft-drinks factory and 210 in other factories), in the age group of 20-45 years of Udupi district, Karnataka, India. Index used for clinical examination was decayed, missing, filled surfaces (DMFS) index and SCI. The mean and standard deviation (SD) of decayed surface (5.8 ± 1.8), missing surface (4.3 ± 2) and filled surface (1.94 ± 1.95) and total DMFS score (12.11 ± 3.8) in soft-drinks factory workers were found to be significantly higher than the other factory workers. The total SCI score (mean and SD) was found to be significantly higher in soft-drinks factory workers (5.83 ± 1.80) compared with other factory workers (4.56 ± 1.45). There was a high correlation obtained between SCI score and DMFS score. The regression equation given by DMFS = 1.178 + 1.866 (SCI scores). The caries experience was higher in workers working in soft-drinks factory and this study also showed that specific caries index can be used as a valid index for assessing dental caries experience.

Three experiments examined elementary school-aged children's and adults' expectations regarding what specialists (i.e., those with narrow domains of expertise) and generalists (i.e., those with broad domains of expertise) are likely to know. Experiment 1 demonstrated developmental differences in the ability to differentiate between generalists and specialists, with younger children believing generalists have more specific trivia knowledge than older children and adults believed. Experiment 2 demonstrated that children and adults expected generalists to have more underlying principles knowledge than specific trivia knowledge about unfamiliar animals. However, they believed that generalists would have more of both types of knowledge than themselves. Finally, Experiment 3 demonstrated that children and adults recognized that underlying principles knowledge can be generalized between topics closely related to the specialists' domains of expertise. However, they did not recognize when this knowledge was generalizable to topics slightly less related, expecting generalists to know only as much as they would. Importantly, this work contributes to the literature by showing how much of and what kinds of knowledge different types of experts are expected to have. In sum, this work provides insight into some of the ways children's notions of expertise change over development. The current research demonstrates that between the ages of 5 and 10, children are developing the ability to recognize how experts' knowledge is likely to be limited. That said, even older children at times struggle to determine the breadth of an experts' knowledge. Copyright © 2014 Elsevier B.V. All rights reserved.

Workers' experience of violence and perceived unsafety can have a profound impact on job satisfaction, job performance, and workers' decision to leave. The aim of the study was to assess the prevalence of physical and non-physical violence among hospital workers, explore the complaints and reactions of victims, assess the relationship between violence and psychosocial/work factors and analyze the levels of perceived unsafety. A cross-sectional study was conducted, via a structured self-administered questionnaire given to all the employees of a major hospital in Italy. Cronbach's alpha coefficient was used to assess the internal consistency of the questionnaire. A logistic regression model was used for data analysis. 903 questionnaires out of 1853 (48.7%) were correctly returned; 11.5% had experience of physical violence and 40.2% had been victims of verbal violence in the previous 12 months. The most common consequences were fear, anger, frustration, and anxiety. Verbal violence was influenced by age, role, department, night/holiday shift work and experience in the current ward. Experiences of physical violence were related to gender, role, and department; 469 responders (51.9%) reported feelings of unsafety, which were related to their professional role, department, shift work, experience of physical or psychological violence, having seen episodes of violence and having received specific training. Our findings suggest that several factors are associated with workplace violence in health care settings and some of these also influenced the levels of perceived unsafety.

Visualization of various working fluids flow regimes in gravity heat pipe

Nemec, Patrik

Heat pipe is device working with phase changes of working fluid inside hermetically closed pipe at specific pressure. The phase changes of working fluid from fluid to vapour and vice versa help heat pipe to transport high heat flux. Amount of heat flux transferred by heat pipe, of course depends on kind of working fluid. The article deal about visualization of various working fluids flow regimes in glass gravity heat pipe by high speed camera and processes casing inside during heat pipe operation. Experiment working fluid flow visualization is performed with two glass heat pipes with different inner diameter (13 mm and 22 mm) filled with water, ethanol and fluorinert FC 72. The working fluid flow visualization explains the phenomena as a working fluid boiling, nucleation of bubbles, and vapour condensation on the wall, vapour and condensate flow interaction, flow down condensate film thickness on the wall occurred during the heat pipe operation.

Accumulating evidence suggests that working memory load is an important factor for the interplay between cognitive and facial-affective processing. However, it is unclear how distraction caused by perception of faces interacts with load-related performance. We developed a modified version of the delayed match-to-sample task wherein task-irrelevant facial distracters were presented early in the rehearsal of pseudoword memoranda that varied incrementally in load size (1-syllable, 2-syllables, or 3-syllables). Facial distracters displayed happy, sad, or neutral expressions in Experiment 1 (N=60) and happy, fearful, or neutral expressions in Experiment 2 (N=29). Facial distracters significantly disrupted task performance in the intermediate load condition (2-syllable) but not in the low or high load conditions (1- and 3-syllables, respectively), an interaction replicated and generalised in Experiment 2. All facial distracters disrupted working memory in the intermediate load condition irrespective of valence, suggesting a primary and general effect of distraction caused by faces. However, sad and fearful faces tended to be less disruptive than happy faces, suggesting a secondary and specific valence effect. Working memory appears to be most vulnerable to social-emotional information at intermediate loads. At low loads, spare capacity is capable of accommodating the combinatorial load (1-syllable plus facial distracter), whereas high loads maximised capacity and deprived facial stimuli from occupying working memory slots to cause disruption.

Long-Term Memory and the Control of Attentional Control

Task-switch costs and in particular the switch-cost asymmetry (i.e., the larger costs of switching to a dominant than a non-dominant task) are usually explained in terms of trial-to-trial carry-over of task-specific control settings. Here we argue that task switches are just one example of situations that trigger a transition from working-memory maintenance to updating, thereby opening working memory to interference from long-term memory. We used a new paradigm that requires selecting a spatial location either on the basis of a central cue (i.e., endogenous control of attention) or a peripheral, sudden onset (i.e., exogenous control of attention). We found a strong cost asymmetry that occurred even after short interruptions of otherwise single-task blocks (Exp. 1-3), but that was much stronger when participants had experienced the competing task under conditions of conflict (Exp. 1-2). Experiment 3 showed that the asymmetric costs were due to interruptions per se, rather than to associative interference tied to specific interruption activities. Experiment 4 generalized the basic pattern across interruptions varying in length or control demands and Experiment 5 across primary tasks with response-selection conflict rather than attentional conflict. Combined, the results support a model in which costs of selecting control settings arise when (a) potentially interfering memory traces have been encoded in long-term memory and (b) working-memory is forced from a maintenance mode into an updating mode (e.g., through task interruptions), thereby allowing unwanted retrieval of the encoded memory traces.

Physical and virtual experimentation are thought to have different affordances for supporting students' learning. Research investigating the use of physical and virtual experiments to support students' learning has identified a variety of, sometimes conflicting, outcomes. Unanswered questions remain about how physical and virtual experiments may impact students' learning and for which contexts and content areas they may be most effective. Using a quasi-experimental design, we examined eighth grade students' (N = 100) learning of physics concepts related to pulleys depending on the sequence of physical and virtual labs they engaged in. Five classes of students were assigned to either the: physical first condition (PF) (n = 55), where students performed a physical pulley experiment and then performed the same experiment virtually, or virtual first condition (VF) (n = 45), with the opposite sequence. Repeated measures ANOVA's were conducted to examine how physical and virtual labs impacted students' learning of specific physics concepts. While we did not find clear-cut support that one sequence was better, we did find evidence that participating in virtual experiments may be more beneficial for learning certain physics concepts, such as work and mechanical advantage. Our findings support the idea that if time or physical materials are limited, using virtual experiments may help students understand work and mechanical advantage.

Modality specificity and integration in working memory: Insights from visuospatial bootstrapping.

The question of how meaningful associations between verbal and spatial information might be utilized to facilitate working memory performance is potentially highly instructive for models of memory function. The present study explored how separable processing capacities within specialized domains might each contribute to this, by examining the disruptive impacts of simple verbal and spatial concurrent tasks on young adults' recall of visually presented digit sequences encountered either in a single location or within a meaningful spatial "keypad" configuration. The previously observed advantage for recall in the latter condition (the "visuospatial bootstrapping effect") consistently emerged across 3 experiments, indicating use of familiar spatial information in boosting verbal memory. The magnitude of this effect interacted with concurrent activity; articulatory suppression during encoding disrupted recall to a greater extent when digits were presented in single locations (Experiment 1), while spatial tapping during encoding had a larger impact on the keypad condition and abolished the visuospatial bootstrapping advantage (Experiment 2). When spatial tapping was performed during recall (Experiment 3), no task by display interaction was observed. Outcomes are discussed within the context of the multicomponent model of working memory, with a particular emphasis on cross-domain storage in the episodic buffer (Baddeley, 2000).

Can we estimate biogeochemical uptake rates in sediments from reach-scale data or vice versa?

Hydrologists and stream ecologists want to understand how reactive transport processes from sub-meter to reach scales aggregate to determine nutrient and carbon export across watersheds. Mesocosm (sub-meter) scale experiments offer the advantage of being tractable and affordable but may be spatially and temporally irrelevant for describing watershed-scale processes. While reach scale experiments sample larger heterogeneities, they provide aggregated information that does not allow for easy detection of hot-spots and hot-moments, and might still be irrelevant for describing watershed processes if they are not conducted under varying flow conditions. We conducted mesocosm (column) and reach-scale experiments along a first-to-eight stream order continuum using nutrient and resazurin tracers to investigate how information collected at the sub-meter scale (mesocosom experiments) compares to that collected at the reach scale, and vice versa. Our work highlights the difficulty of finding useful patterns not only across stream orders (i.e., for the same type of experiment) but also across experiments. Our results offer quantitative perspective on why hydrologists and stream ecologists must depart from the status quo of conducting solute-specific (e.g., only N), site-specific (primarily headwaters) and single-season (mainly summer) experiments to understand controls on nutrient retention.

Although it is well established that combat-related PTSD can lead to reduced quality of life, less is known about the relative effect of PTSD on different aspects of former service members' post-military readjustment. Moreover, research on female veterans' reintegration experiences is limited. This study aimed to document the work and family quality of life of post-9/11 male and female veterans and evaluate the gender-specific impact of PTSD on veterans' work and family outcomes. A national sample of 524 post-9/11 veterans completed mailed surveys as part of a longitudinal study. Descriptive and regression-based analyses were gender-stratified and weighted to enhance representativeness to the larger population. With a few notable exceptions, the majority of post-9/11 U.S. veterans reported high work and family quality of life. PTSD was not associated with either employment or relationship status; however, it did predict poorer work and family functioning and satisfaction for both men and women, with the most consistent negative effects on intimate relationships. Several gender differences were found, primarily with respect to work experiences. Although most post-9/11 veterans appear to be doing well in both their work and family lives, results support the need for interventions that can mitigate the negative effect of PTSD and other associated mental health conditions on several aspects of work and family quality of life. Findings contribute to research suggesting both similarities and differences in the post-military readjustment of male and female post-9/11 veterans and underscore the need for additional consideration of the unique work-related challenges women experience following military service.

To evaluate the validity of widely used questionnaire items on work schedule using objective registry data as reference. A cohort study of hospital employees who responded to a self-administered questionnaire on work schedule in 2008, 2012 and 2014 and were linked to individual-level pay-roll-based records on work shifts. For predictive validity, leisure-time fatigue was assessed. According to the survey data in 2014 (n=8896), 55% of the day workers had at least 1 year of earlier shift work experience. 8% of the night shift workers changed to day work during the follow-up. Using pay-roll data as reference, questions on 'shift work with night shifts' and 'permanent night work' showed high sensitivity (96% and 90%) and specificity (92% and 97%). Self-reported 'regular day work' showed moderate sensitivity (73%), but high specificity (99%) and 'shift work without night shifts' showed low sensitivity (62%) and moderate specificity (87%). In multivariate logistic regression analysis, the age-adjusted, sex-adjusted and baseline fatigue-adjusted association between 'shift work without night shifts' and leisure-time fatigue was lower for self-reported compared with objective assessment (1.30, 95% CI 0.94 to 1.82, n=1707 vs 1.89, 95% CI 1.06 to 3.39, n=1627). In contrast, shift work with night shifts, compared with permanent day work, was similarly associated with fatigue in the two assessments (2.04, 95% CI 1.62 to 2.57, n=2311 vs 1.82, 95% CI 1.28 to 2.58, n=1804). The validity of self-reported assessment of shift work varies between work schedules. Exposure misclassification in self-reported data may contribute to bias towards the null in shift work without night shifts. Published by the BMJ Publishing Group Limited.

OPTIMAL EXPERIMENT DESIGN FOR MAGNETIC RESONANCE FINGERPRINTING

Zhao, Bo; Haldar, Justin P.; Setsompop, Kawin; Wald, Lawrence L.

2017-01-01

Magnetic resonance (MR) fingerprinting is an emerging quantitative MR imaging technique that simultaneously acquires multiple tissue parameters in an efficient experiment. In this work, we present an estimation-theoretic framework to evaluate and design MR fingerprinting experiments. More specifically, we derive the Cramér-Rao bound (CRB), a lower bound on the covariance of any unbiased estimator, to characterize parameter estimation for MR fingerprinting. We then formulate an optimal experiment design problem based on the CRB to choose a set of acquisition parameters (e.g., flip angles and/or repetition times) that maximizes the signal-to-noise ratio efficiency of the resulting experiment. The utility of the proposed approach is validated by numerical studies. Representative results demonstrate that the optimized experiments allow for substantial reduction in the length of an MR fingerprinting acquisition, and substantial improvement in parameter estimation performance.

Language influences music harmony perception: effects of shared syntactic integration resources beyond attention

PubMed Central

Willems, Roel M.; Hagoort, Peter

2016-01-01

Many studies have revealed shared music–language processing resources by finding an influence of music harmony manipulations on concurrent language processing. However, the nature of the shared resources has remained ambiguous. They have been argued to be syntax specific and thus due to shared syntactic integration resources. An alternative view regards them as related to general attention and, thus, not specific to syntax. The present experiments evaluated these accounts by investigating the influence of language on music. Participants were asked to provide closure judgements on harmonic sequences in order to assess the appropriateness of sequence endings. At the same time participants read syntactic garden-path sentences. Closure judgements revealed a change in harmonic processing as the result of reading a syntactically challenging word. We found no influence of an arithmetic control manipulation (experiment 1) or semantic garden-path sentences (experiment 2). Our results provide behavioural evidence for a specific influence of linguistic syntax processing on musical harmony judgements. A closer look reveals that the shared resources appear to be needed to hold a harmonic key online in some form of syntactic working memory or unification workspace related to the integration of chords and words. Overall, our results support the syntax specificity of shared music–language processing resources. PMID:26998339

The presentation will focus on topics of interest to young women pursuing an engineering or scientific career, such as intrinsic personality traits of most engineers, average salaries for the various types of engineers, appropriate preparation classes at the high school and undergraduate levels, gaining experience through internships, summer jobs and graduate school, skills necessary but not always included in engineering curricula (i.e., multimedia, computer skills, communication skills), the work environment, balancing family and career, and sexual harassment. Specific examples from the speaker's own experience in NASA's Space Life Sciences Program will be used to illustrate the above topics. In particular, projects from Extravehicular Activity and Protective Systems research and Regenerative Life Support research will be used as examples of real world problem-solving to enable human exploration of the solar system.

Plant communication: mediated by individual or blended VOCs?

PubMed

Ueda, Hirokazu; Kikuta, Yukio; Matsuda, Kazuhiko

2012-02-01

Plants emit volatile organic compounds (VOCs) as a means to warn other plants of impending danger. Nearby plants exposed to the induced VOCs prepare their own defense weapons in response. Accumulated data supports this assertion, yet much of the evidence has been obtained in laboratories under artificial conditions where, for example, a single VOC might be applied at a concentration that plants do not actually experience in nature. Experiments conducted outdoors suggest that communication occurs only within a limited distance from the damaged plants. Thus, the question remains as to whether VOCs work as a single component or a specific blend, and at which concentrations VOCs elicit insect and pathogen defenses in undamaged plants. We discuss these issues based on available literature and our recent work, and propose future directions in this field.

This study draws on an in-depth investigation of factors that influenced the career decisions of junior doctors. Junior doctors in the UK can choose to enter specialty training (ST) programmes within 2 years of becoming doctors. Their specialty choices contribute to shaping the balance of the future medical workforce, with views on general practice (GP) careers of particular interest because of current recruitment difficulties. This paper examines how experiences of medical work and perceptions about specialty training shape junior doctors' career decisions. Twenty doctors in the second year of a Foundation Training Programme in England were recruited. Purposive sampling was used to achieve a diverse sample from respondents to an online survey. Narrative interviewing techniques encouraged doctors to reflect on how experiences during medical school and in medical workplaces had influenced their preferences and perceptions of different specialties. They also spoke about personal aspirations, work priorities and their wider future.Junior doctors' decisions were informed by knowledge about the requirements of ST programmes and direct observation of the pressures under which ST doctors worked. When they encountered negative attitudes towards a specialty they had intended to choose, some became defensive while others kept silent. Achievement of an acceptable work-life balance was a central objective that could override other preferences.Events linked with specific specialties influenced doctors' attitudes towards them. For example, findings confirmed that while early, positive experiences of GP work could increase its attractiveness, negative experiences in GP settings had the opposite effect. Junior doctors' preferences and perceptions about medical work are influenced by multiple intrinsic and extrinsic factors and experiences. This paper highlights the importance of understanding how perceptions are formed and preferences are developed, as a basis for generating learning and working environments that nurture students and motivate their professional careers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Sufficient sleep is necessary for optimal performance and the delivery of safe and effective health care. To establish an empirical understanding of physician fatigue, the present study investigated the factors that contributed to the amount and the quality of sleep among obstetricians and gynecologists (ob-gyns). A survey of personal and work experiences was sent to 495 eligible physicians belonging to the American College of Obstetricians and Gynecologists (ACOG). Data were obtained from 287 ob-gyns for a response rate of 58.0%. Associations between sleep-related items and measures of stress and work-related factors were explored. Ob-gyns in our sample reported sleeping an average of 6.5 hours a night with 29.2% indicating that they received very or fairly bad quality of sleep. Average amount and quality of sleep were found to be independently related to the hours worked weekly, colleague support for a work-home balance, practice setting, perceived work-control, physician-specific stressors and perceived stress. In summary models, hours worked and perceived stress scores consistently emerged as predictors of amount of sleep. Overall, findings explained a small portion of the variance in sleep. Considering the multitude of factors that contribute to sleep, subtle associations warrant further investigation.

2017-06-12

The goal of this research was to examine the moderating effect of work recovery strategies on the relationship between occupational stress experienced by firefighters and mental health symptoms. Work recovery strategies were identified through semistructured interviews with 20 firefighters and a literature search on recovery strategies. A total of 7 work recovery strategies emerged using the 2 methods: work-related talks, stress-related talks, time with coworkers/supervisor, exercise, recreational activities, relaxation, and mastery experiences. Using a prospective study design with a 1-month time interval in a sample of 268 firefighters, experienced occupational stress at Time 1 was positively related to mental health symptoms at Time 2. In addition, with the exception of spending time with coworkers/supervisor, exercise and mastery experiences, recovery strategies at Time 1 were negatively related to mental health symptoms at Time 2. Lastly, all work recovery strategies, except stress-related talks and relaxation, moderated the relationship between experienced occupational stress at Time 1 and mental health symptoms at Time 2. Specifically, the positive relationship between experienced occupational stress and mental health symptoms was stronger when firefighters engaged in low, rather than high, work recovery strategies. Implications for research and practice are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Conscientiousness, openness to experience and extraversion as predictors of nursing work performance: a facet-level analysis.

This study examined the relationships between the personality traits of conscientiousness, openness and extraversion at trait and facet-levels and three indicators of work role performance; proficiency, 'adaptivity' and proactivity measured at individual, team and organisational levels. This is one of the first studies to explore the relationship between personality, measured at trait and facet-level and performance using a comprehensive range of performance indicators. An online survey of 393 nurses from health-care organisations across Australia was conducted to test hypothesised relationships. Path analyses revealed numerous relationships between personality, measured at both trait and facet-levels, and work role performance. Conscientiousness was highlighted as the strongest driver of work role performance across all the indicators, with extraversion also strongly associated with work role performance. Openness to experience, previously considered a week predictor of performance, was, when examined at the facet-level, related to all of the work role performance indicators. Results suggests a bandwidth effect, where the personality traits drive global performance while the facets drive specific performance. Better understanding of the relationship between personality and work role performance will help nurse managers to foster the fit between individual and organisation, improving job satisfaction, engagement, retention and performance in role. © 2015 John Wiley & Sons Ltd.

Thriving, not just surviving, in emotionally demanding fields of practice.

Research within the disciplines of Social Work and Education has for sometime acknowledged the tragedy, trauma, conflict and misery that can be experienced by workers in their associated professions. More recently, there has been an aligned interest in the role of passion, emotion and energy in sustaining these professionals through such experiences. This paper contributes to the growing literature in this area by reporting on a study conducted with five social workers and six teachers who work in Australian lower socioeconomic, urban-fringe and communities. It also engages the concept of the 'personal domain' to explore how these social workers and teachers cannot only survive, but can actually thrive in demanding work contexts. The methodology adopted for the study was an appreciative enquiry approach, where these professionals, each with over a decade of experience in urban-fringe communities, were recruited via non-probability, purposive, snowballing techniques and interviewed about what sustained them in their work during November 2008-February 2009. Thematic analysis of the interviews found that participants not only identified specific survival strategies, but could also articulate how their life experiences, ideologies, beliefs, values and other life resources informed their work in ways that aided their flourishing as professionals. The paper concludes by calling for further research into the work of social work and teaching professionals from a 'personal domain' perspective and considering the potential implications of such research for these professions, particularly in terms of promoting professional trajectories characterised first by endurance, and then by development and triumph. © 2011 Blackwell Publishing Ltd.

Being a Positive Bystander: Male Antiviolence Allies’ Experiences of “Stepping Up”

2014-01-01

As bystander approaches become increasingly prevalent elements of sexual and domestic violence prevention efforts, it is necessary to better understand the factors that support or impede individuals in taking positive action in the face of aggressive or disrespectful behavior from others. This study presents descriptive findings about the bystander experiences of 27 men who recently became involved in antiviolence against women work. More specifically, we describe the consistency with which respondents actively intervene in the speech or behavior of others, the strategies they use, and the factors they weigh as they deliberate taking action. Respondents report a complex and interrelated set of individual and contextual influences on their choices within bystander opportunities, which hold implications for both violence-specific models of bystander behavior and for prevention intervention development.

Information was collected on the efficacy of fault-tolerant software by conducting two large-scale controlled experiments. In the first, an empirical study of multi-version software (MVS) was conducted. The second experiment is an empirical evaluation of self testing as a method of error detection (STED). The purpose ot the MVS experiment was to obtain empirical measurement of the performance of multi-version systems. Twenty versions of a program were prepared at four different sites under reasonably realistic development conditions from the same specifications. The purpose of the STED experiment was to obtain empirical measurements of the performance of assertions in error detection. Eight versions of a program were modified to include assertions at two different sites under controlled conditions. The overall structure of the testing environment for the MVS experiment and its status are described. Work to date in the STED experiment is also presented.

Smuggling of illicit drugs by concealing them within the human body (body packer) is a medical-legal issue that has increased in the last few decades. Physicians, especially those working in the emergency department, should be familiar with the diagnostic and therapeutic management -usually conservative management- of this type of patient and their possible complications. The present article reviews the general concepts and physiopathology associated with transport of packages in the digestive tract and describes the experience of a referral hospital with a protocol specifically designed for these patients.

2015-10-02

As tools for quantitative label-free mass spectrometry (MS) rapidly develop, a consensus about the best practices is not apparent. In the work described here we compared popular statistical methods for detecting differential protein expression from quantitative MS data using both controlled experiments with known quantitative differences for specific proteins used as standards as well as "real" experiments where differences in protein abundance are not known a priori. Our results suggest that data-driven reproducibility-optimization can consistently produce reliable differential expression rankings for label-free proteome tools and are straightforward in their application.

How to survive (and enjoy) doing a thesis: the experiences of a methodological working group.

Giddings, Lynne S; Wood, Pamela J

2006-03-01

'Doing a thesis', whether for Masters or PhD, can be a lonely and tortuous journey. This article offers a complementary process to the traditional apprenticeship supervision model. It describes the experiences of students who during their thesis research met monthly in a grounded theory working group. They reflected on their experiences during a focus group interview. After describing the background to how the group started in 1999 and exploring some of the ideas in the literature concerning the thesis experience, the article presents the interview. To focus the presentation, specific questions are used as category headings. Overall, the participants found attending the group was a "life-line" that gave them "hope" and was complementary to the supervision process. Through the support of peers, guidance from those ahead in the process, and consultancy with teachers and visiting methodological scholars, these students not only successfully completed their theses, but reported that they had some enjoyment along the way. This is the fifteenth in a series of articles which have been based on interviews with nursing and midwifery researchers, and were primarily designed to offer the beginning researcher a first-hand account of the experience of using particular methodologies.

Worrying about the Future: An Episodic Specificity Induction Impacts Problem Solving, Reappraisal, and Well-Being

PubMed Central

Jing, Helen G.; Madore, Kevin P.; Schacter, Daniel L.

2015-01-01

Previous research has demonstrated that an episodic specificity induction – brief training in recollecting details of a recent experience – enhances performance on various subsequent tasks thought to draw upon episodic memory processes. Existing work has also shown that mental simulation can be beneficial for emotion regulation and coping with stressors. Here we focus on understanding how episodic detail can affect problem solving, reappraisal, and psychological well-being regarding worrisome future events. In Experiment 1, an episodic specificity induction significantly improved participants’ performance on a subsequent means-end problem solving task (i.e., more relevant steps) and an episodic reappraisal task (i.e., more episodic details) involving personally worrisome future events compared with a control induction not focused on episodic specificity. Imagining constructive behaviors with increased episodic detail via the specificity induction was also related to significantly larger decreases in anxiety, perceived likelihood of a bad outcome, and perceived difficulty to cope with a bad outcome, as well as larger increases in perceived likelihood of a good outcome and indicated use of active coping behaviors compared with the control. In Experiment 2, we extended these findings using a more stringent control induction, and found preliminary evidence that the specificity induction was related to an increase in positive affect and decrease in negative affect compared with the control. Our findings support the idea that episodic memory processes are involved in means-end problem solving and episodic reappraisal, and that increasing the episodic specificity of imagining constructive behaviors regarding worrisome events may be related to improved psychological well-being.

Short-term memory and working memory in children with blindness: support for a domain general or domain specific system?

PubMed

Swanson, H Lee; Luxenberg, Diana

2009-05-01

The study explored the contribution of two component processes (phonological and executive) to blind children's memory performance. Children with blindness and sight were matched on gender, chronological age, and verbal intelligence and compared on measures of short-term memory (STM) and working memory (WM). Although the measures were highly correlated, the results from two experiments indicated that the blind children were superior to sighted children on measures of STM, but not on measures of WM. The results supported the notion that children with blindness have advantages on memory tasks that draw upon resources from the phonological loop. However, comparable performance between the ability groups on WM measures suggests there are domain specific aspects in the executive system.

An innovative approach to providing collaborative education to undergraduate students in the area of child maltreatment.

Johnson, Lisa

2015-05-01

Frontline workers in the area of child welfare often enter the field without having taken any specialized coursework in the area of child maltreatment. This article discusses an interdisciplinary certificate program that is specifically designed to teach persons from various academic areas the knowledge and skills necessary to work with children who experience maltreatment. The child advocacy studies certificate program specifically focuses on coursework in the area of child maltreatment and child advocacy to better train future frontline workers in their vital roles. This certificate will decrease underreporting of child abuse cases by mandated reporters by making them more aware of the signs and symptoms of child maltreatment and also give students a greater understanding of how to work with individuals from various fields.

Set-specific capture can be reduced by preemptively occupying a limited-capacity focus of attention.

PubMed

Moore, Katherine Sledge; Weissman, Daniel H

2011-01-01

Recent work has shown that contingent attentional capture effects can be especially large when multiple attentional sets for color guide visual search (Moore & Weissman, 2010). In particular, this research suggests that detecting a target-colored (e.g., orange) distractor leads the corresponding attentional set (e.g., identify orange letters) to enter a limited-capacity focus of attention in working memory, where it remains briefly while the distractor is being attended. Consequently, the ability to identify a differently-colored (e.g., green) target 100-300 ms later is impaired because the appropriate set (e.g., identify green letters) cannot also enter the focus of attention. In two experiments, we investigated whether such set-specific capture can be reduced by preemptively occupying the focus of attention. As predicted, a target-colored central distractor presented 233 ms before a target-colored peripheral distractor eliminated set-specific capture arising from the peripheral distractor. Moreover, this effect was observed only when the central distractor's color (e.g., orange) (a) matched a different set than the upcoming peripheral distractor's color (e.g., green) and (b) matched the same set as the upcoming central target's color (e.g., orange). We conclude that the same working memory limitations that give rise to set-specific capture can be preemptively exploited to reduce it.

Teaching community diagnosis to medical students: evaluation of a case study approach.

PubMed

Bair, C W

1980-01-01

A unique case study approach to training medical students in community diagnosis techniques was initiated at the Medical College of Ohio at Toledo. This paper describes the five elements of this teaching method: preliminary specification of target community and data base; group problem-solving requirement; specification of desired output; defined performance objectives; and regularly scheduled time for analysis. Experience with the case study method over two years was evaluated to identify specific strengths and weaknesses. The identified strengths include use of limited educational time to introduce community health problems, development of experience in a collegial team work setting, and specific awareness of the types of data useful to the analysis of community health service problems. Negative evaluations suggested that the method was not conducive to the development of skills in three areas: ability to establish the relative importance of health problems in communities; ability to identify an appropriate health system response to a community health problem from feasible alternatives; and ability to anticipate the community impact of health program modifications or improvements. Potential explanations for these deficiencies include: need for increased didactic support in the classroom for particular skill areas; need to establish a direct field experience in community diagnosis; inappropriateness of the data base used for evaluation of particular skills; and the probability that quantitative analysis, as used in this evaluation, may not be sufficient in and of itself to measure the outcome of a community diagnosis experience.

TGI Monday?: drug-dependent outpatients report lower stress and more happiness at work than elsewhere.

PubMed

Epstein, David H; Preston, Kenzie L

2012-01-01

In the general population, experience-sampling studies show that work is the aspect of daily life most associated with momentary unhappiness and a desire to be elsewhere. We assessed whether this holds true for urban outpatients in treatment for heroin and cocaine dependence. In a 25-week natural-history study, 79 employed methadone-maintained misusers of heroin and cocaine carried electronic diaries on which mood and behavior were assessed up to five times per day. Being at work was associated with lower stress, greater happiness, and lower drug craving. Work accounted for 14% of the variance in stress, 30% of the variance in happiness, and 50% of the variance in cocaine craving. Participants with skilled jobs reported more positive and less negative mood states (and lower cocaine craving) at all times compared to participants with semi/unskilled jobs, although the latter reported greater mood improvement at work. In all participants, mood improvements occurred specifically in the presence of coworkers (not other companions). Our seemingly unusual findings might be specific to substance-disorder patients (for whom work may be a respite from drug-using companions), but might also hold for other urban dwellers of similar socioeconomic backgrounds (for whom work may be a respite from environmental stressors).

Moed, M. C.; Kelley, R. B.

1988-02-01

To increase task flexibility in a robotic assembly environment, a hierarchical planning and execution system is being developed which will map user specified 3D part assembly tasks into various target robotic work cells, and execute these tasks efficiently using manipulators and sensors available in the work cell. One level of this hierarchy, the Supervisor, is responsible for assigning subtasks of a system generated Task Plan to a set of task specific Specialists and on-line coordination of the activity of these Specialists to accomplish the user specified assembly. The design of the Supervisor can be broken down into five major functional blocks: resource management; concurrency detection; task scheduling; error recovery; and interprocess communication. The Supervisor implementation has been completed on a VAX 11/750 under a Unix environment. PC card Pick-Insert experiments were performed to test this implementation. To test the robustness of the architecture, the Supervisor was then transported to a new work cell under a VMS environment. The experiments performed under Supervisor control in both implementations are discussed after a brief explanation of the functional blocks of the Supervisor and the other levels in the hierarchy.

Medical and scientific assessments as the basis for prioritization and resource allocation for new drug treatment - experiences from five years of systematic workIn this study, the process for introduction of new drug treatment in Region Västra Götaland (second largest region in Sweden encompassing 1.6 million inhabitants, 17% of all inhabitants in Sweden) is described. A working group, consisting of persons with relevant expertise and declared conflicts of interest, contributes with medical and scientific assessments as the basis for prioritization and resource allocation. In 2011-2015, 111 new drug treatments were nominated by healthcare representatives, 84 fulfilled the criteria for assessments by the working group, and 57 (68%) were deemed to have high/medium high priority to receive introduction financing according to the severity of disease, the benefit/risk balance, and the level of evidence. When analyzing subsequent costs for new drug treatments for which data could be obtained and specifically evaluated, the results indicate that the process can contribute to rational use of medicines.

White coats and no trousers: narrating the experiences of women technicians in medical laboratories, 1930–90

2015-01-01

Laboratory technicians are a vital part of any working lab. Not only is their knowledge and expertise important for the success of research, but they also often maintain the lab's intellectual and social life. Despite the importance of their work, they are rarely acknowledged in publications, and leave only a few traces within the historical record—the voices of women laboratory technicians are even harder to uncover. This paper attempts to correct this imbalance by presenting the narratives of women who worked as laboratory technicians at places such as the National Institute for Medical Research (NIMR), the Wellcome Research Laboratories, and established hospital and university labs in Cambridge, Oxford and London. The data were collected though narrative interviews. Specifically, the paper looks at the roles of these women within the lab, their experiences of the social and gender dynamics of the lab, and the development of expertise in regard to the work they carried out and the extent to which they received credit for their contributions to science.

2015-08-01

The brain functional network perspective forms the basis to relate mechanisms of brain functions. This work analyzes the network mechanisms related to human emotion based on synchronization measure - phase-locking value in EEG to formulate the emotion specific brain functional network. Based on network dissimilarities between emotion and rest tasks, most reactive channel pairs and the reactive band corresponding to emotions are identified. With the identified most reactive pairs, the subject-specific functional network is formed. The identified subject-specific and emotion-specific dynamic network pattern show significant synchrony variation in line with the experiment protocol. The same network pattern are then employed for classification of emotions. With the study conducted on the 4 subjects, an average classification accuracy of 62 % was obtained with the proposed technique.

The purpose of this study is to determine the relationship between the psychosocial work environment and labor market experiences (including unemployment) on mental health among adults living with HIV. We used data provided by 538 participants at clinical and community sites across Ontario, Canada. Generalized estimating equation models showed that employment was associated with lower depressive symptoms. For employed participants, adverse psychosocial work conditions, specifically job insecurity, psychological demands, and decision authority were associated with depressive symptoms. For the entire sample, the number of adverse psychosocial work conditions was associated with higher depressive symptoms while participants working in poor quality jobs reported similar levels of depressive symptoms than those who were unemployed or not in the labor force. This study showed that poor quality employment (as assessed by having a high number of adverse psychosocial work exposures) was associated with a similar level of depressive symptoms as unemployment, suggesting that "bad jobs" may not offer the same mental health benefits as "good jobs." Policies to improve employment outcomes should take the quality of employment into account to maximize mental health benefits as better employment may lead to better mental health.

Nucleolin forms a specific complex with a fragment of the viral (minus) strand of minute virus of mice DNA.

Nucleolin, a major nucleolar protein, forms a specific complex with the genome (a single-stranded DNA molecule of minus polarity) of parvovirus MVMp in vitro. By means of South-western blotting experiments, we mapped the binding site to a 222-nucleotide motif within the non-structural transcription unit, referred to as NUBE (nucleolin-binding element). The specificity of the interaction was confirmed by competitive gel retardation assays. DNaseI and nuclease S1 probing showed that NUBE folds into a secondary structure, in agreement with a computer-assisted conformational prediction. The whole NUBE may be necessary for the interaction with nucleolin, as suggested by the failure of NUBE subfragments to bind the protein and by the nuclease footprinting experiments. The present work extends the previously reported ability of nucleolin to form a specific complex with ribosomal RNA, to a defined DNA substrate. Considering the tropism of MVMp DNA replication for host cell nucleoli, these data raise the possibility that nucleolin may contribute to the regulation of the parvoviral life-cycle.

Although awareness of the importance of the research capacity of community-based organizations (CBOs) is growing, a uniform framework of the research capacity domains within CBOs has not yet been developed. To develop a framework and instrument (the Community REsearch Activity assessment Tool [CREAT]) for assessing the research activity and capacity of CBOs that incorporates awareness of the different data collection and analysis priorities of CBOs. We conducted a review of existing tools for assessing research capacity to identify key capacity domains. Instrument items were developed through an iterative process with CBO representatives and community researchers. The CREAT was then pilot tested with 30 CBOs. The four primary domains of the CREAT framework include 1) organizational support for research, 2) generalizable experiences, 3) research specific experiences, and 4) funding. Organizations reported a high prevalence of activities in the research-specific experiences domain, including conducting literature reviews (70%), use of research terminology (83%), and primary data collection (100%). Respondents see research findings as important to improve program and service delivery, and to seek funds for new programs and services. Funders, board members, and policymakers are the most important dissemination audiences. The work reported herein advances the field of CBO research capacity by developing a systematic framework for assessing research activity and capacity relevant to the work of CBOs, and by developing and piloting an instrument to assess activity in these domains.

In vivo tomographic imaging of the fluorescence pharmacokinetic parameters in tissues can provide additional specific and quantitative physiological and pathological information to that of fluorescence concentration. This modality normally requires a highly-sensitive diffuse fluorescence tomography (DFT) working in dynamic way to finally extract the pharmacokinetic parameters from the measured pharmacokinetics-associated temporally-varying boundary intensity. This paper is devoted to preliminary experimental validation of our proposed direct reconstruction scheme of instantaneous sampling based pharmacokinetic-DFT: A highly-sensitive DFT system of CT-scanning mode working with parallel four photomultiplier-tube photon-counting channels is developed to generate an instantaneous sampling dataset; A direct reconstruction scheme then extracts images of the pharmacokinetic parameters using the adaptive-EKF strategy. We design a dynamic phantom that can simulate the agent metabolism in living tissue. The results of the dynamic phantom experiments verify the validity of the experiment system and reconstruction algorithms, and demonstrate that system provides good resolution, high sensitivity and quantitativeness at different pump speed.

In the natural world, learning emerges from the joy of play, experimentation, and inquiry as part of everyday life. However, this kind of informal learning is often difficult to integrate within structured educational curricula. This report describes an educational program that embeds naturalistic learning into formal high school, college, and graduate school science class work. Our experience is based on work with hundreds of high school, college, and graduate students enrolled in traditional science classes in which mannequin simulators were used to teach physiological principles. Specific case scenarios were integrated into the curriculum as problem-solving exercises chosen to accentuate the basic science objectives of the course. This report also highlights the historic and theoretical basis for the use of mannequin simulators as an important physiology education tool and outlines how the authors' experience in healthcare education has been effectively translated to nonclinical student populations. Particular areas of focus include critical-thinking and problem-solving behaviors and student reflections on the impact of the teaching approach.

Although the mechanisms of visual working memory (VWM) have been studied extensively in recent years, the active property of VWM has received less attention. In the current study, we examined how VWM integrates sequentially presented stimuli by focusing on the role of Gestalt principles, which are important organizing principles in perceptual integration. We manipulated the level of Gestalt cues among three or four sequentially presented objects that were memorized. The Gestalt principle could not emerge unless all the objects appeared together. We distinguished two hypotheses: a perception-alike hypothesis and an encoding-specificity hypothesis. The former predicts that the Gestalt cue will play a role in information integration within VWM; the latter predicts that the Gestalt cue will not operate within VWM. In four experiments, we demonstrated that collinearity (Experiment 1) and closure (Experiment 2) cues significantly improved VWM performance, and this facilitation was not affected by the testing manner (Experiment 3) or by adding extra colors to the memorized objects (Experiment 4). Finally, we re-established the Gestalt cue benefit with similarity cues (Experiment 5). These findings together suggest that VWM realizes and uses potential Gestalt principles within the stored representations, supporting a perception-alike hypothesis. Copyright © 2015 Elsevier B.V.

Recent studies have emphasized the importance of childhood memories of threatening experiences and submissiveness in a diversity of psychological disorders. The purpose of this work was to study their specific relationship with hallucination proneness and ideas of reference in healthy subjects. The ELES scale for measuring memory of adverse childhood experiences, the DES-II scale for measuring dissociation, the LSHS-R scale for measuring hallucination proneness, and the REF for ideas of reference were applied to a sample of 472 subjects. A positive association was found between childhood memories of adverse experiences and hallucination proneness and ideas of reference, on one hand, and dissociation on the other. A mediation analysis showed that dissociation was a mediator between the memory of adverse childhood experiences and hallucination proneness on one hand, and ideas of reference on the other. When the role of mediator of the types of dissociative experiences was studied, it was found that absorption and depersonalization mediated between adverse experiences and hallucination proneness. However, this mediating effect was not found between adverse experiences and ideas of reference. The relationship between these last two variables was direct. The results suggest that childhood memories of adverse experiences are a relevant factor in understanding hallucination proneness and ideas of reference. Similarly, dissociation is a specific mediator between adverse childhood experiences and hallucination proneness. © 2018 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Spiritual Dryness as a Measure of a Specific Spiritual Crisis in Catholic Priests: Associations with Symptoms of Burnout and Distress

2013-01-01

Spirituality/religiosity is recognized as a resource to cope with burdening life events and chronic illness. However, less is known about the consequences of the lack of positive spiritual feelings. Spiritual dryness in clergy has been described as spiritual lethargy, a lack of vibrant spiritual encounter with God, and an absence of spiritual resources, such as spiritual renewal practices. To operationalize experiences of “spiritual dryness” in terms of a specific spiritual crisis, we have developed the “spiritual dryness scale” (SDS). Here, we describe the validation of the instrument which was applied among other standardized questionnaires in a sample of 425 Catholic priests who professionally care for the spiritual sake of others. Feelings of “spiritual dryness” were experienced occasionally by up to 40%, often or even regularly by up to 13%. These experiences can explain 44% of variance in daily spiritual experiences, 30% in depressive symptoms, 22% in perceived stress, 20% in emotional exhaustion, 19% in work engagement, and 21% of variance of ascribed importance of religious activity. The SDS-5 can be used as a specific measure of spiritual crisis with good reliability and validity in further studies. PMID:23843867

Despite evidence linking trait mindfulness and mindfulness training with a broad range of effects, still little is known about its underlying active mechanisms. Mindfulness is commonly defined as (1) the ongoing monitoring of present-moment experience (2) with an orientation of acceptance. Building on conceptual, clinical, and empirical work, we describe a testable theoretical account to help explain mindfulness effects on cognition, affect, stress, and health outcomes. Specifically, Monitor and Acceptance Theory (MAT) posits that (1), by enhancing awareness of one's experiences, the skill of attention monitoring explains how mindfulness improves cognitive functioning outcomes, yet this same skill can increase affective reactivity. Second (2), by modifying one's relation to monitored experience, acceptance is necessary for reducing affective reactivity, such that attention monitoring and acceptance skills together explain how mindfulness improves negative affectivity, stress, and stress-related health outcomes. We discuss how MAT contributes to mindfulness science, suggest plausible alternatives to the account, and offer specific predictions for future research. Copyright © 2016 Elsevier Ltd.

The purpose of this code specification is to describe an algorithm for solving the Euler equations of hydrodynamics in a 2D rectangular region in sufficient detail to allow a software developer to produce an implementation on their target platform using their programming language of choice without requiring detailed knowledge and experience in the field of computational fluid dynamics. It should be possible for a software developer who is proficient in the programming language of choice and is knowledgable of the target hardware to produce an efficient implementation of this specification if they also possess a thorough working knowledge of parallelmore » programming and have some experience in scientific programming using fields and meshes. On modern architectures, it will be important to focus on issues related to the exploitation of the fine grain parallelism and data locality present in this algorithm. This specification aims to make that task easier by presenting the essential details of the algorithm in a systematic and language neutral manner while also avoiding the inclusion of implementation details that would likely be specific to a particular type of programming paradigm or platform architecture.« less

Evolution of the ATLAS PanDA workload management system for exascale computational science

An important foundation underlying the impressive success of data processing and analysis in the ATLAS experiment [1] at the LHC [2] is the Production and Distributed Analysis (PanDA) workload management system [3]. PanDA was designed specifically for ATLAS and proved to be highly successful in meeting all the distributed computing needs of the experiment. However, the core design of PanDA is not experiment specific. The PanDA workload management system is capable of meeting the needs of other data intensive scientific applications. Alpha-Magnetic Spectrometer [4], an astro-particle experiment on the International Space Station, and the Compact Muon Solenoid [5], an LHC experiment, have successfully evaluated PanDA and are pursuing its adoption. In this paper, a description of the new program of work to develop a generic version of PanDA will be given, as well as the progress in extending PanDA's capabilities to support supercomputers and clouds and to leverage intelligent networking. PanDA has demonstrated at a very large scale the value of automated dynamic brokering of diverse workloads across distributed computing resources. The next generation of PanDA will allow other data-intensive sciences and a wider exascale community employing a variety of computing platforms to benefit from ATLAS' experience and proven tools.

2006-12-01

As a SPS Summer Intern from the University of Wisconsin-River Falls, I spent nine weeks in the Washington, D.C. area working with the American Physical Society. My work dealt primarily with the development of a ComPADRE outreach website, Physics To Go, which offers the public opportunities to engage in informal physics learning. Specific tasks that I performed included locating content to feature on the homepage, obtaining photographer permissions, and cataloging quality websites into the digital library. At the conclusion of the summer, I accepted an offer to continue working on Physics To Go and have further contributed to its expansion. Participating in this internship has influenced my life in several respects, and as a result, I will be enrolling in a graduate program this coming year. Additionally, I am making plans to participate in a National Student Exchange program and am considering a career with a greater emphasis on research. The internship has served as an invaluable and irreplaceable experience.

Work Term Assignment Spring 2017

2017-01-01

My tour in the Engineering Robotics directorate exceeded my expectations. I learned lessons about Creo, manufacturing and assembly, collaboration, and troubleshooting. During my first tour, last spring, I used Creo on a smaller project, but had limited experience with it before starting in the Dynamic Systems Test branch this spring. I gained valuable experience learning assembly design, sheet metal design and designing with intent for manufacturing and assembly. These skills came from working both on the hatch and the floor. I also learned to understand the intent of other designers on models I worked with. While redesigning the floor, I was modifying an existing part and worked to understand what the previous designer had done to make it fit with the new model. Through working with the machine shop and in the mock-up, I learned much more about manufacturing and assembly. I used a Dremel, rivet gun, belt sander, and countersink for the first time. Through taking multiple safety training for different machine shops, I learned new machine shop safety skills specific to each one. This semester also gave me new collaborative opportunities. I collaborated with engineers within my branch as well as with Human Factors and the building 10 machine shop. This experience helped me learn how to design for functionality and assembly, not only for what would be easiest in my designs. In addition to these experiences, I learned many lessons in troubleshooting. I was the first person in my office to use a Windows 10 computer. This caused unexpected issues with NASA services and programs, such as the Digital Data Management Server (DDMS). Because of this, I gained experience finding solutions to lockout and freeze issues as well as Creo specific settings. These will be useful skills to have in the future and will be implemented in future rotations. This co-op tour has motivated me more to finish my degree and pursue my academic goals. I intend to take a machining Career Gateway Elective in the Fall to improve my skills in building as well as designing with manufacturing intent. I am also inspired to take more mechatronics CGE courses before I graduate to learn more about the crossover between mechanical and electrical engineering. This semester, I worked on multiple projects and had the opportunity to learn from engineers of different disciplines. I became proficient in Creo 2.0, a program I had not used significantly before. I finished modifying the hatch for 3D print and made sizeable modifications to the nose floor support design. I also gained hands-on experience that will be useful in my engineering career in the future. I would consider all of these major achievements from this spring semester. Lastly, I learned to ask more questions and to search for the right people to find answers which I know will be a valuable skill in the future. This summer, I will be completing my last rotation in the Flight Operations Directorate at Ellington Air Field. After this last tour, I will be returning to school for the Fall, Spring and Summer. I will graduate in August of 2018. I am looking forward to learning more about the different jobs available to engineers. This division works directly with many different types of aircrafts and I am excited to learn more about this focus of engineering. The Aircraft Operations Division values team work greatly and I intend to improve my interpersonal skills by working with them this summer.

Patients' Experience of Myositis and Further Validation of a Myositis-specific Patient Reported Outcome Measure - Establishing Core Domains and Expanding Patient Input on Clinical Assessment in Myositis. Report from OMERACT 12.

The Outcome Measures in Rheumatology (OMERACT) myositis working group was established to examine patient-reported outcomes (PRO) as well as to validate patient-reported outcome measures (PROM) in myositis. Qualitative studies using focus group interviews and cognitive debriefing of the myositis-specific Myositis Activities Profile (MAP) were used to explore the experience of adults living with polymyositis (PM) and dermatomyositis (DM). Preliminary results underscore the importance of patient input in the development of PROM to ensure content validity. Results from multicenter focus groups indicate the range of symptoms experienced including pain, fatigue, and impaired cognitive function, which are not currently assessed in myositis. Preliminary cognitive debriefing of the MAP indicated that while content was deemed relevant and important, several activities were not included; and that questionnaire construction and wording may benefit from revision. A research agenda was developed to continue work toward optimizing PRO assessment in myositis with 2 work streams. The first would continue to conduct and analyze focus groups until saturation in the thematic analysis was achieved to develop a framework that encompassed the patient-relevant aspects of myositis. The second would continue cognitive debriefing of the MAP to identify potential areas for revision. There was agreement that further work would be needed for inclusion body myositis and juvenile dermatomyositis, and that the inclusion of additional contributors such as caregivers and individuals from the pharmaceutical/regulatory spheres would be desirable. The currently used PROM do not assess symptoms or the effects of disease that are most important to patients; this emphasizes the necessity of patient involvement. Our work provides concrete examples for PRO identification.

Financing of health systems to achieve the health Millennium Development Goals in low-income countries.

2010-01-30

Concern that underfunded and weak health systems are impeding the achievement of the health Millennium Development Goals in low-income countries led to the creation of a High Level Taskforce on Innovative International Financing for Health Systems in September, 2008. This report summarises the key challenges faced by the Taskforce and its Working Groups. Working Group 1 examined the constraints to scaling up and costs. Challenges included: difficulty in generalisation because of scarce and context-specific health-systems knowledge; no consensus for optimum service-delivery approaches, leading to wide cost differences; no consensus for health benefits; difficulty in quantification of likely efficiency gains; and challenges in quantification of the financing gap owing to uncertainties about financial commitments for health. Working Group 2 reviewed the different innovative mechanisms for raising and channelling funds. Challenges included: variable definitions of innovative finance; small evidence base for many innovative finance mechanisms; insufficient experience in harmonisation of global health initiatives; and inadequate experience in use of international investments to improve maternal, newborn, and child health. The various mechanisms reviewed and finally recommended all had different characteristics, some focusing on specific problems and some on raising resources generally. Contentious issues included the potential role of the private sector, the rights-based approach to health, and the move to results-based aid. The challenges and disagreements that arose during the work of the Taskforce draw attention to the many issues facing decision makers in low-income countries. International donors and recipient governments should work together to improve the evidence base for strengthening health systems, increase long-term commitments, and improve accountability through transparent and inclusive national approaches.

The role of aging in intra-item and item-context binding processes in visual working memory.

PubMed

Peterson, Dwight J; Naveh-Benjamin, Moshe

2016-11-01

Aging is accompanied by declines in both working memory and long-term episodic memory processes. Specifically, important age-related memory deficits are characterized by performance impairments exhibited by older relative to younger adults when binding distinct components into a single integrated representation, despite relatively intact memory for the individual components. While robust patterns of age-related binding deficits are prevalent in studies of long-term episodic memory, observations of such deficits in visual working memory (VWM) may depend on the specific type of binding process being examined. For instance, a number of studies indicate that processes involved in item-context binding of items to occupied spatial locations within visual working memory are impaired in older relative to younger adults. Other findings suggest that intra-item binding of visual surface features (e.g., color, shape), compared to memory for single features, within visual working memory, remains relatively intact. Here, we examined each of these binding processes in younger and older adults under both optimal conditions (i.e., no concurrent load) and concurrent load (e.g., articulatory suppression, backward counting). Experiment 1 revealed an age-related intra-item binding deficit for surface features under no concurrent load but not when articulatory suppression was required. In contrast, in Experiments 2 and 3, we observed an age-related item-context binding deficit regardless of the level of concurrent load. These findings reveal that the influence of concurrent load on distinct binding processes within VWM, potentially those supported by rehearsal, is an important factor mediating the presence or absence of age-related binding deficits within VWM.

2011-03-01

This work examines the methane production potential for the anaerobic co-digestion of swine manure (SM) with winery wastewater (WW). Batch and semi-continuous experiments were carried out under mesophilic conditions. Batch experiments revealed that the highest specific methane yield was 348 mL CH(4)g(-1) COD added, obtained at 85.4% of WW and 0.7 g COD g(-1)VS. Specific methane yield from SM alone was 27 mL CH(4)g(-1) COD added d(-1). Furthermore, specific methane yields were 49, 87 and 107 mL CH(4)g(-1) COD added d(-1) for the reactors co-digesting mixtures with 10% WW, 25% WW and 40% WW, respectively. Co-digestion with 40% WW improved the removal efficiencies up to 52% (TCOD), 132% (SCOD) and 61% (VSS) compared to SM alone. These results suggest that methane can be produced very efficiently by the co-digestion of swine manure with winery wastewater. Copyright © 2011 Elsevier Ltd. All rights reserved.

[Rehabilitation in the view of small and midsized enterprises: knowledge, appreciation and possibilities to cooperate - results of the KoRB-project].

2008-12-01

The experiences of small and midsized enterprises (SME) with medical rehabilitation were investigated in the KoRB-Study (KoRB= KOoperation Rehabilitation und Betrieb) for the first time. Opportunities for a targeted cooperation between the statutory pension insurance and these enterprises were explored. Based on explorative interviews, Westphalian employers, members of the works council, occupational health practitioners and employees were interrogated about the image of and their appreciation of medical rehabilitation in the work setting. Experience with rehabilitation and the level of information on rehabilitation were recorded as well as the compatibility of rehabilitation with operative processes in the working site. In addition rehab hospitals were asked about their experience in cooperating with enterprises. 697 employers of small and midsized enterprises, 458 members of the works councils, 73 occupational health practitioners, 47 rehab hospitals and 3 509 employees, who are members of the German Pension Fund of Westphalia, took part in the survey. Especially employers perceived rehabilitation positively and reported good experiences. Among the employees, those who had taken part in rehabilitation showed the highest appreciation. Occupational health practitioners were more restrained in their appraisal. Some of them complained about a lack of sustainability. The different target groups of the survey felt differently well informed about rehabilitation - best ratings came from the occupational health practitioners, worst ratings from the employees. All groups would welcome more accessible information in case of need. Medical rehabilitation in its standard form of "3 weeks full-time" often causes severe logistic problems in SME (e. g., replacement of employee, loss of experience). However the financial burden is perceived as less problematic. Employers favour alternative rehab models, which allow part-time working. Many employees, who expressed a need for rehabilitation, refrained from applying for rehabilitation on account of worries about loosing their employment. Both rehab clinicians and occupational health practitioners argued in favour of improved communication and cooperation in order to adapt medical rehab to the specific requirements of the working place and to assure a smooth reintegration into work.

The impact of negative emotions on self-concept abstraction depends on accessible information processing styles.

PubMed

Isbell, Linda M; Rovenpor, Daniel R; Lair, Elicia C

2016-10-01

Research suggests that anger promotes global, abstract processing whereas sadness and fear promote local, concrete processing (see Schwarz & Clore, 2007 for a review). Contrary to a large and influential body of work suggesting that specific affective experiences are tethered to specific cognitive outcomes, the affect-as-cognitive-feedback account maintains that affective experiences confer positive or negative value on currently dominant processing styles, and thus can lead to either global or local processing (Huntsinger, Isbell, & Clore, 2014). The current work extends this theoretical perspective by investigating the impact of discrete negative emotions on the self-concept. By experimentally manipulating information processing styles and discrete negative emotions that vary in appraisals of certainty, we demonstrate that the impact of discrete negative emotions on the spontaneous self-concept depends on accessible processing styles. When global processing was accessible, individuals in angry (negative, high certainty) states generated more abstract statements about themselves than individuals in either sad (Experiment 1) or fearful (Experiment 2; negative, low certainty) states. When local processing was made accessible, however, the opposite pattern emerged, whereby individuals in angry states generated fewer abstract statements than individuals in sad or fearful states. Together these studies provide new insights into the mechanisms through which discrete emotions influence cognition. In contrast to theories assuming a dedicated link between emotions and processing styles, these results suggest that discrete emotions provide feedback about accessible ways of thinking, and are consistent with recent evidence suggesting that the impact of affect on cognition is highly context-dependent.

Targeted mentoring refers to mentoring aimed at a particular population. This article presents the evaluation of a mentoring program for lesbian, gay, bisexual, and transgender (LGBT) persons in social work education. Forty-three mentors and protégés responded to a survey regarding their program experiences. The results highlight the need for targeted mentoring, although some disparities of experience for mentors and protégés in this program are apparent. In general, mentors felt positive about participating, giving back to the LGBT community, and were more satisfied with their experiences than were the protégés, who were looking for more specific types of instrumental and psychosocial support.

Deciphering the Landauer-Büttiker Transmission Function from Single Molecule Break Junction Experiments

NASA Astrophysics Data System (ADS)

Reuter, Matthew; Tschudi, Stephen

When investigating the electrical response properties of molecules, experiments often measure conductance whereas computation predicts transmission probabilities. Although the Landauer-Büttiker theory relates the two in the limit of coherent scattering through the molecule, a direct comparison between experiment and computation can still be difficult. Experimental data (specifically that from break junctions) is statistical and computational results are deterministic. Many studies compare the most probable experimental conductance with computation, but such an analysis discards almost all of the experimental statistics. In this work we develop tools to decipher the Landauer-Büttiker transmission function directly from experimental statistics and then apply them to enable a fairer comparison between experimental and computational results.

Working on the moon: The Apollo experience

The successful completion of any scientific or engineering project on the Moon will depend, in part, on human ability to do useful work under lunar conditions. In making informed decisions about such things as the use of humans rather than robots for specific tasks, the scheduling of valuable human time, and the design and selection of equipment and tools, good use can be made of the existing experience base. During the six completed landing missions, Apollo lunar surface crews conducted 160 astronaut-hours of extra-vehicular activities (EVAs) and also spent a similar sum of waking hours working in the cramped confinesmore » of the Lunar Module. The first three missions were primarily proof-tests of flight hardware and procedures. The ability to land equipment and consumables was very modest but, despite stay times of no more than 32 hours, the crews of Apollos 11, 12, and 14 were able to test their mobility and their capability of doing useful work outside the spacecraft. For the last three missions, thanks to LM modifications which enabled landings with significant amounts of cargo, stay times more than doubled to three days. The crews were able to use Lunar Rovers to conduct extensive local exploration and to travel up to 10 kilometers away from their immediate landing sites. During these final missions, the astronauts spent enough time doing work of sufficient complexity that their experience should be of use in the formulation early-stage lunar base operating plans. 2 refs.« less

Production characterization and working characteristics in DICI engine of Pongamia biodiesel.

PubMed

Srinivasa Rao, M; Anand, R B

2015-11-01

Renewable energy plays a predominant role in solving the current energy requirement problems and biodiesel is a promising alternative fuel to tide over the energy crisis and conserve fossil fuels. The present work investigates an eco-friendly substitute for the replacement of fossil fuels and the experiments are designed to determine the effects of a catalyst in the biodiesel production processes. Pongamia pinnata oil was utilized to produce the biodiesel by using catalysts namely KOH and NaOH and the properties of the fuel were found by using Carbon Hydrogen Nitrogen Sulfur (CHNS) elemental analysis, Fourier Transform Infrared (FTIR) Spectroscopy, Gas Chromatography & Mass Spectrometry (GC-MS), and Proton Nuclear Magnetic Resonance ((1)H NMR) Spectroscopy and the thermophysical properties were compared with those of neat diesel. In continuation, the working characteristics of the biodiesel and biodiesel-water emulsions were accomplished in a four stroke compression ignition engine and the results were compared to those of neat diesel. It was found that the exhaust emission characteristics like brake specific carbon monoxide (BSCO), brake specific hydrocarbons (BSHC) and smoke opacity were better for neat biodiesel (except brake specific nitric oxide BSNO) than those of neat diesel.

Coming Out in Class: Challenges and Benefits of Active Learning in a Biology Classroom for LGBTQIA Students.

PubMed

Cooper, Katelyn M; Brownell, Sara E

As we transition our undergraduate biology classrooms from traditional lectures to active learning, the dynamics among students become more important. These dynamics can be influenced by student social identities. One social identity that has been unexamined in the context of undergraduate biology is the spectrum of lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) identities. In this exploratory interview study, we probed the experiences and perceptions of seven students who identify as part of the LGBTQIA community. We found that students do not always experience the undergraduate biology classroom to be a welcoming or accepting place for their identities. In contrast to traditional lectures, active-learning classes increase the relevance of their LGBTQIA identities due to the increased interactions among students during group work. Finally, working with other students in active-learning classrooms can present challenges and opportunities for students considering their LGBTQIA identity. These findings indicate that these students' LGBTQIA identities are affecting their experience in the classroom and that there may be specific instructional practices that can mitigate some of the possible obstacles. We hope that this work can stimulate discussions about how to broadly make our active-learning biology classes more inclusive of this specific population of students. © 2016 K. M. Cooper and S. E.

Positive benefits of caring on nurses' motivation and well-being: a diary study about the role of emotional regulation abilities at work.

PubMed

Recent research reveals that not all job demands have negative effects on workers' well-being and suggests that the negative or positive effects of specific job demands depend on the occupational sector. Specifically, emotional job demands form the heart of the work for nurses and for this reason they can be interpreted by nurses as a challenge that promotes motivation and well-being among these professionals, especially if personal and job resources become available. The study had two objectives. First, to examine whether daily emotional demands within a nursing work context have a positive effect on nurses' daily motivation at work (vigour) and well-being at home (vitality and positive affect). Second, to explore whether this positive effect could be enhanced by nurses' emotional regulation abilities. This research used a diary design to explore daily experiences and to analyze how variations in specific job or personal characteristics can affect levels of motivation and well-being across days. Fifty-three nurses working in different Spanish hospitals and primary health care centres completed a general questionnaire and a diary booklet over 5 consecutive working days in two different moments, after work and at night (N=53 participants and N=265 observations). In line with our hypotheses, multi-level analyses revealed that, on the one hand, day-level emotional demands at work had a positive effect on vigour at work and on vitality at home. On the other hand, analyses showed that nurses with higher emotional regulation abilities have more motivation at work and well-being at home when they have to face high emotional demands at work, showing a spill over effect after work. These findings support the idea that emotional demands from the nursing profession can act as challenges which promote motivation and well-being, especially if internal emotional resources become available.

The segregation of many bacterial chromosomes is dependent on the interactions of ParB proteins with centromere-like DNA sequences called parS that are located close to the origin of replication. In this work, we have investigated the binding of Bacillus subtilis ParB to DNA in vitro using a variety of biochemical and biophysical techniques. We observe tight and specific binding of a ParB homodimer to the parS sequence. Binding of ParB to non-specific DNA is more complex and displays apparent positive co-operativity that is associated with the formation of larger, poorly defined, nucleoprotein complexes. Experiments with magnetic tweezers demonstrate that non-specific binding leads to DNA condensation that is reversible by protein unbinding or force. The condensed DNA structure is not well ordered and we infer that it is formed by many looping interactions between neighbouring DNA segments. Consistent with this view, ParB is also able to stabilize writhe in single supercoiled DNA molecules and to bridge segments from two different DNA molecules in trans. The experiments provide no evidence for the promotion of non-specific DNA binding and/or condensation events by the presence of parS sequences. The implications of these observations for chromosome segregation are discussed. PMID:25572315

Few long-term longitudinal studies have examined how dimensions of personality are related to work lives, especially in women. We propose a life-course framework for studying work over time, from preparatory activities (in the 20s) to descending work involvement (after age 60), using 50 years of life data from the women in the Mills Longitudinal Study. We hypothesized differential work effects for Extraversion (work as pursuit of rewards), Openness (work as self-actualization), and Conscientiousness (work as duty) and measured these 3 traits as predictor variables when the women were still in college. In a prospective longitudinal design, we then studied how these traits predicted the women's subsequent work lives from young adulthood to age 70 and how these effects depended on the changing sociocultural context. Specifically, the young adulthood of the Mills women in the mid-1960s was rigidly gender typed and family oriented; neither work nor education variables at that time were predicted from earlier personality traits. However, as women's roles changed, later work variables became related to all 3 traits, as expected from current Big Five theory and research. For example, early personality traits predicted the timing of involvement in work, the kinds of jobs chosen, and the status and satisfaction achieved, as well as continued work participation and financial security in late adulthood. Early traits were also linked to specific cultural influences, such as the traditional feminine role, the women's movement, and graduate education for careers. 2011 APA, all rights reserved

How the brain works is nowadays synonymous with how different parts of the brain work together and the derivation of mathematical descriptions for the functional connectivity patterns that can be objectively derived from data of different neuroimaging techniques. In most cases static networks are studied, often relying on resting state recordings. Here, we present a quantitative study of dynamic reconfiguration of connectivity for event-related experiments. Our motivation is the development of a methodology that can be used for personalized monitoring of brain activity. In line with this motivation, we use data with visual stimuli from a typical subject that participated in different experiments that were previously analyzed with traditional methods. The earlier studies identified well-defined changes in specific brain areas at specific latencies related to attention, properties of stimuli, and tasks demands. Using a recently introduced methodology, we track the event-related changes in network organization, at source space level, thus providing a more global and complete view of the stages of processing associated with the regional changes in activity. The results suggest the time evolving modularity as an additional brain code that is accessible with noninvasive means and hence available for personalized monitoring and clinical applications.

Professionals who work in academia, advocacy, and industry often carry out mutually exclusive activities related to research and clinical care. However, there are several examples of collaboration among such professionals that ultimately allows for improved scientific and clinical understanding. This commentary recounts our particular experience (a collaboration between geneticists at the Universities of Minnesota and Utah, the 4p- Support Group, and Lineagen, Inc) and reviews other similar projects. We formally propose this collaborative method as a conduit for future clinical research programs. Specifically, we encourage academicians, directors of family/advocacy/support groups, and members of industry to establish partnerships and document their experiences. The medical community as a whole will benefit from such partnerships and, specifically, families will teach us lessons that could never be learned in a laboratory or textbook. © 2014 Wiley Periodicals, Inc.

Famous talker effects in spoken word recognition.

2014-01-01

Previous work has demonstrated that talker-specific representations affect spoken word recognition relatively late during processing. However, participants in these studies were listening to unfamiliar talkers. In the present research, we used a long-term repetition-priming paradigm and a speeded-shadowing task and presented listeners with famous talkers. In Experiment 1, half the words were spoken by Barack Obama, and half by Hillary Clinton. Reaction times (RTs) to repeated words were shorter than those to unprimed words only when repeated by the same talker. However, in Experiment 2, using nonfamous talkers, RTs to repeated words were shorter than those to unprimed words both when repeated by the same talker and when repeated by a different talker. Taken together, the results demonstrate that talker-specific details can affect the perception of spoken words relatively early during processing when words are spoken by famous talkers.

Bringing Earth Magnetism Research into the High School Physics Classroom

2015-12-01

We present our work in progress from an NSF CAREER project that aims to integrate paleomagnetic research and secondary school physics education. The research project is aimed at quantifying the strength and geometry of the Precambrian geomagnetic field. Investigation of the geomagnetic field behavior is crucial for understanding the mechanisms of field generation, and the development of the Earth's atmosphere and biosphere, and can serve as a focus for connecting high-level Earth science research with a standard physics curriculum. High school science teachers have participated in each summer field and research component of the project, gaining field and laboratory research experience, sets of rock and mineral samples, and classroom-tested laboratory magnetism activities for secondary school physics and earth science courses. We report on three field seasons of teacher field experiences and two years of classroom testing of paleomagnetic research materials merged into physics instruction on magnetism. Students were surveyed before and after dedicated instruction for both perceptions and attitude towards earth science in general, then more specifically on earth history and earth magnetism. Students were also surveyed before and after instruction on major earth system and magnetic concepts and processes, particularly as they relate to paleomagnetic research. Most students surveyed had a strongly positive viewpoint towards the study of Earth history and the importance of studying Earth Sciences in general, but were significantly less drawn towards more specific topics such as mineralogy and magnetism. Students demonstrated understanding of Earth model and the basics of magnetism, as well as the general timing of life, atmospheric development, and magnetic field development. However, detailed knowledge such as the magnetic dynamo, how the magnetic field has changed over time, and connections between earth magnetism and the development of an atmosphere remained largely misunderstood even after specific instruction, laboratory activities, and research examples. Ongoing work is examining the effectiveness of specific classroom and laboratory activities on student perceptions and misconceptions - which models work best to develop deeper understanding and appreciation of paleomagnetic research.

International public health research involving interpreters: a case study from Bangladesh.

Pitchforth, Emma; van Teijlingen, Edwin

2005-06-28

Cross-cultural and international research are important components of public health research, but the challenges of language barriers and working with interpreters are often overlooked, particularly in the case of qualitative research. A case-study approach was used to explore experiences of working with an interpreter in Bangladesh as part of a research project investigating women's experiences of emergency obstetric care. Data from the researcher's field notes provided evidence of experiences in working with an interpreter and show how the model of interviewing was adapted over time to give a more active role to the interpreter. The advantages of a more active role were increased rapport and "flow" in interviews. The disadvantages included reduced control from the researcher's perspective. Some tensions between the researcher and interpreter remained hard to overcome, irrespective of the model used. Independent transcription and translation of the interviews also raised questions around accuracy in translation. The issues examined in this case study have broader implications for public health research. Further work is needed in three areas: 1) developing effective relationships with interpreters; 2) the impact of the interpreter on the research process; and 3) the accuracy of the translation and level of analysis needed in any specific public health research. Finally, this paper highlights the importance to authors of reflecting on the potential impact of translation and interpretation on the research process when disseminating their research.

Communication has been identified as an important attribute of clinical leadership in nursing. However, there is a paucity of research on its relevance in mental health nursing. This article presents the findings of a grounded theory informed study exploring the attributes and characteristics required for effective clinical leadership in mental health nursing, specifically the views of nurses working in mental health about the importance of effective communication in day to day clinical leadership. In-depth interviews were conducted to gain insight into the participants' experiences and views on clinical leadership in mental health nursing. The data that emerged from these interviews were constantly compared and reviewed, ensuring that any themes that emerged were based on the participants' own experiences and views. Participants recognized that effective communication was one of the attributes of effective clinical leadership and they considered communication as essential for successful working relationships and improved learning experiences for junior staff and students in mental health nursing. Four main themes emerged: choice of language; relationships; nonverbal communication, and listening and relevance. Participants identified that clinical leadership in mental health nursing requires effective communication skills, which enables the development of effective working relationships with others that allows them to contribute to the retention of staff, improved outcomes for clients, and the development of the profession.

Abstract This article considers the effects of work in the south Wales coal industry either side of the turn of the twentieth century and, specifically, the ways in which work aged workers prematurely. It examines the consequences of working practices for miners’ bodies, the expedients utilized by miners to try and cope with the effects of premature ageing, and the consequences for their living standards, experiences and status. It situates these phenomena in the contexts of industrial relations and welfare provision. In so doing, the article engages with historiographies of the life-cycle, the aged, and pensions provision in modern Britain. PMID:27134572

The 1995 publication of Goleman's Emotional Intelligence triggered a revolution in mental health promotion. Goleman's examination of Gardner's work on multiple intelligences and current brain research, and review of successful programs that promoted emotional health, revealed a common objective among those working to prevent specific problem behaviors: producing knowledgeable, responsible, nonviolent, and caring individuals. Advances in research and field experiences confirm that school-based programs that promote social and emotional learning (SEL) in children can be powerful in accomplishing these goals. This article reviews the work of the Collaborative to Advance Social and Emotional Learning (CASEL), its guidelines for promoting mental health in children and youth based on SEL, key principles, and examples of exemplary programs.

Several major modifications were made to the design presented at the PDR. The frame was deleted in favor of a "frameless" design which will provide a substantially improved cell packing factor. Potential shaded cell damage resulting from operation into a short circuit can be eliminated by a change in the cell series/parallel electrical interconnect configuration. The baseline process sequence defined for the MEPSON was refined and equipment design and specification work was completed. SAMICS cost analysis work accelerated, format A's were prepared and computer simulations completed. Design work on the automated cell interconnect station was focused on bond technique selection experiments.

Aberrant Salience, Self-Concept Clarity, and Interview-Rated Psychotic-Like Experiences

Many social-cognitive models of psychotic-like symptoms posit a role for self-concept and aberrant salience. Previous work has shown that the interaction between aberrant salience and self-concept clarity is associated with self-reported psychotic-like experiences. In the current research with two structured interviews, the interaction between aberrant salience and self-concept clarity was found to be associated withinterview-rated psychotic-like experiences. The interaction was associated withpsychotic-like experiences composite scores, delusional ideation, grandiosity, and perceptual anomalies. In all cases, self-concept clarity was negatively associated with psychotic-like experiences at high levels of aberrant salience, but unassociated with psychotic-like experiences at low levels of aberrant salience. The interaction was specific to positive psychotic-like experiences and not present for negative or disorganized ratings. The interaction was not mediated by self-esteem levels. These results provide further evidence that aberrant salience and self-concept clarity play an important role in the generation of psychotic-like experiences. PMID:25102085

Mealtimes are opportunities for social interactions and expressions of individual and family identity, and serve as a microcosm of the broader lives of families living with dementia. The Eating Together study and its resulting Life Nourishment Theory (LNT) explicated the importance of mealtimes for honouring individual and family identities in the context of dementia. This sub-study examined a specific ethnocultural group with cultural food-ways and caring expectations, to determine if the concept of honouring identity needed to be modified or extended. Using active interview techniques, two Cantonese speaking researchers completed dyad/triad family and individual interviews with six Chinese Canadian immigrant families, recruited from two service providers in a large, urban, multicultural city. This sub-study provided insight into the challenges and rewards of mealtimes for Chinese immigrant families with dementia in the community and specifically provided further insights into the honouring identity concept. Although LNT and specifically the honouring identity concept was generally confirmed in this group, some culturally-specific themes were also identified. This work serves as a basis for future studies examining the meaning and experience of mealtimes in specific cultural groups living with dementia. Such work would confirm if the LNT can be applied to specific ethnocultural groups as well as the general population living with dementia. © The Author(s) 2012.

A Semantic Lexicon-Based Approach for Sense Disambiguation and Its WWW Application

NASA Astrophysics Data System (ADS)

di Lecce, Vincenzo; Calabrese, Marco; Soldo, Domenico

This work proposes a basic framework for resolving sense disambiguation through the use of Semantic Lexicon, a machine readable dictionary managing both word senses and lexico-semantic relations. More specifically, polysemous ambiguity characterizing Web documents is discussed. The adopted Semantic Lexicon is WordNet, a lexical knowledge-base of English words widely adopted in many research studies referring to knowledge discovery. The proposed approach extends recent works on knowledge discovery by focusing on the sense disambiguation aspect. By exploiting the structure of WordNet database, lexico-semantic features are used to resolve the inherent sense ambiguity of written text with particular reference to HTML resources. The obtained results may be extended to generic hypertextual repositories as well. Experiments show that polysemy reduction can be used to hint about the meaning of specific senses in given contexts.

Chromatin immunoprecipitation followed by sequencing (ChIP-seq) experiments revolutionized genome-wide profiling of transcription factors and histone modifications. Although maturing sequencing technologies allow these experiments to be carried out with short (36-50 bps), long (75-100 bps), single-end, or paired-end reads, the impact of these read parameters on the downstream data analysis are not well understood. In this paper, we evaluate the effects of different read parameters on genome sequence alignment, coverage of different classes of genomic features, peak identification, and allele-specific binding detection. We generated 101 bps paired-end ChIP-seq data for many transcription factors from human GM12878 and MCF7 cell lines. Systematic evaluations using in silico variations of these data as well as fully simulated data, revealed complex interplay between the sequencing parameters and analysis tools, and indicated clear advantages of paired-end designs in several aspects such as alignment accuracy, peak resolution, and most notably, allele-specific binding detection. Our work elucidates the effect of design on the downstream analysis and provides insights to investigators in deciding sequencing parameters in ChIP-seq experiments. We present the first systematic evaluation of the impact of ChIP-seq designs on allele-specific binding detection and highlights the power of pair-end designs in such studies.

Accelerating the connection between experiments and models: The FACE-MDS experience

The mandate is clear for improving communication between models and experiments to better evaluate terrestrial responses to atmospheric and climatic change. Unfortunately, progress in linking experimental and modeling approaches has been slow and sometimes frustrating. Recent successes in linking results from the Duke and Oak Ridge free-air CO2 enrichment (FACE) experiments with ecosystem and land surface models - the FACE Model-Data Synthesis (FACE-MDS) project - came only after a period of slow progress, but the experience points the way to future model-experiment interactions. As the FACE experiments were approaching their termination, the FACE research community made an explicit attempt to work together with the modeling community to synthesize and deliver experimental data to benchmark models and to use models to supply appropriate context for the experimental results. Initial problems that impeded progress were: measurement protocols were not consistent across different experiments; data were not well organized for model input; and parameterizing and spinning up models that were not designed for simulating a specific site was difficult. Once these problems were worked out, the FACE-MDS project has been very successful in using data from the Duke and ORNL FACE experiment to test critical assumptions in the models. The project showed, for example, that the stomatal conductance model most widely used in models was supported by experimental data, but models did not capture important responses such as increased leaf mass per unit area in elevated CO2, and did not appropriately represent foliar nitrogen allocation. We now have an opportunity to learn from this experience. New FACE experiments that have recently been initiated, or are about to be initiated, include a eucalyptus forest in Australia; the AmazonFACE experiment in a primary, tropical forest in Brazil; and a mature oak woodland in England. Cross-site science questions are being developed that will have a strong modeling framework, and modelers and experimentalists will work to establish common measurement protocols and data format. By starting the model-experiment connection early and learning from our past experiences, we expect to significantly shorten the time lags between advances in process-oriented studies and large-scale models.

Electrophysiological Repetition Effects in Persons with Mild Cognitive Impairment depend upon Working Memory Demand.

Forms of implicit memory, including repetition effects, are preserved relative to explicit memory in clinical Alzheimer's disease. Consequently, cognitive interventions for persons with Alzheimer's disease have been developed that leverage this fact. However, despite the clinical robustness of behavioral repetition effects, altered neural mechanisms of repetition effects are studied as biomarkers of both clinical Alzheimer's disease and pre-morbid Alzheimer's changes in the brain. We hypothesized that the clinical preservation of behavioral repetition effects results in part from concurrent operation of discrete memory systems. We developed two experiments that included probes of emotional repetition effects differing in that one included an embedded working memory task. We found that neural repetition effects manifested in patients with amnestic mild cognitive impairment, the earliest form of clinical Alzheimer's disease, during emotional working memory tasks, but they did not manifest during the task that lacked the embedded working memory manipulation. Specifically, the working memory task evoked neural repetition effects in the P600 time-window, but the same neural mechanism was only minimally implicated in the task without a working memory component. We also found that group differences in behavioral repetition effects were smaller in the experiment with a working memory task. We suggest that cross-domain cognitive challenge can expose "defunct" neural capabilities of individuals with amnestic mild cognitive impairment. Copyright © 2018. Published by Elsevier Ltd.

Training programs for volunteers prior to their working in palliative care are well-established in India. However, few studies report on continuing professional development programs for this group. To conduct a preliminary assessment of educational needs of volunteers working in palliative care for developing a structured formal continuing professional development program for this group. Cross-sectional observational study conducted in the Department of Palliative Medicine of a tertiary care cancer institute in India. Participant volunteers completed a questionnaire, noting previous training, years of experience, and a comprehensive list of topics for inclusion in this program, rated in order of importance according to them. Descriptive statistics for overall data and Chi-square tests for categorical variables for group comparisons were applied using Statistical Package for Social Sciences version 18. Fourteen out of 17 volunteers completed the questionnaire, seven having 5-10-years experience in working in palliative care. A need for continuing professional development program was felt by all participants. Communication skills, more for children and elderly specific issues were given highest priority. Spiritual-existential aspects and self-care were rated lower in importance than psychological, physical, and social aspects in palliative care. More experienced volunteers (>5 years of experience) felt the need for self-care as a topic in the program than those with less (<5-years experience) (P < 0.05). Understanding palliative care volunteers' educational needs is essential for developing a structured formal continuing professional development program and should include self-care as a significant component.

Hydrophobic fluorescent probes introduce artifacts into single molecule tracking experiments due to non-specific binding.

Single-molecule techniques are powerful tools to investigate the structure and dynamics of macromolecular complexes; however, data quality can suffer because of weak specific signal, background noise and dye bleaching and blinking. It is less well-known, but equally important, that non-specific binding of probe to substrates results in a large number of immobile fluorescent molecules, introducing significant artifacts in live cell experiments. Following from our previous work in which we investigated glass coating substrates and demonstrated that the main contribution to this non-specific probe adhesion comes from the dye, we carried out a systematic investigation of how different dye chemistries influence the behaviour of spectrally similar fluorescent probes. Single-molecule brightness, bleaching and probe mobility on the surface of live breast cancer cells cultured on a non-adhesive substrate were assessed for anti-EGFR affibody conjugates with 14 different dyes from 5 different manufacturers, belonging to 3 spectrally homogeneous bands (491 nm, 561 nm and 638 nm laser lines excitation). Our results indicate that, as well as influencing their photophysical properties, dye chemistry has a strong influence on the propensity of dye-protein conjugates to adhere non-specifically to the substrate. In particular, hydrophobicity has a strong influence on interactions with the substrate, with hydrophobic dyes showing much greater levels of binding. Crucially, high levels of non-specific substrate binding result in calculated diffusion coefficients significantly lower than the true values. We conclude that the physic-chemical properties of the dyes should be considered carefully when planning single-molecule experiments. Favourable dye characteristics such as photostability and brightness can be offset by the propensity of a conjugate for non-specific adhesion.

Effects of Solar Geoengineering on Meridional Energy Transport and the ITCZ

Russotto, R. D.; Ackerman, T. P.; Frierson, D. M.

2016-12-01

The polar amplification of warming and the ability of the intertropical convergence zone (ITCZ) to shift to the north or south are two very important problems in climate science. Examining these behaviors in global climate models (GCMs) running solar geoengineering experiments is helpful not only for predicting the effects of solar geoengineering, but also for understanding how these processes work under increased CO2. Both polar amplification and ITCZ shifts are closely related to the meridional transport of moist static energy (MSE) by the atmosphere. In this study we examine changes in MSE transport in 10 fully coupled GCMs in Experiment G1 of the Geoengineering Model Intercomparison Project, in which the solar constant is reduced to compensate for abruptly quadrupled CO2 concentrations. In this experiment, poleward MSE transport decreases relative to preindustrial conditions in all models, in contrast to the CMIP5 abrupt4xCO2 experiment, in which poleward MSE transport increases. The increase in poleward MSE transport under increased CO2 is due to latent heat transport, as specific humidity increases faster in the tropics than at the poles; this mechanism is not present under G1 conditions, so the reduction in dry static energy transport due to a weakened equator-to-pole temperature gradient leads to weaker energy transport overall. Changes in cross-equatorial MSE transport in G1, meanwhile, are anticorrelated with shifts in the ITCZ. The northward ITCZ shift in G1 is 0.14 degrees in the multi-model mean and ranges from -0.33 to 0.89 degrees between the models. We examine the specific forcing and feedback terms responsible for changes in MSE transport in G1 by running experiments with a moist energy balance model. This work will help identify the largest sources of uncertainty regarding ITCZ shifts under solar geoengineering, and will help improve our understanding of the reasons for the residual polar amplification that occurs in the G1 experiment.

Genome engineering with TALENs and ZFNs: repair pathways and donor design.

Genome engineering with targetable nucleases depends on cellular pathways of DNA repair after target cleavage. Knowledge of how those pathways work, their requirements and their active factors, can guide experimental design and improve outcomes. While many aspects of both homologous recombination (HR) and nonhomologous end joining (NHEJ) are shared by a broad range of cells and organisms, some features are specific to individual situations. This article reviews the influence of repair mechanisms on the results of gene targeting experiments, with an emphasis on lessons learned from experiments with Drosophila.

A microcontroller-based stimulator that can be flexible programmed after it has been implanted into a rat was studied. Programmability enables implanted stimulators to generate customized, complex protocols for experiments. After implantation, a coded light pulse train that contains information of specific identification will unlock a certain stimulator. If a command that changing the parameters is received, the microcontroller will update its flash memory after it affirms the commands. The whole size of it is only 1.6 cubic centimeters, and it can work for a month. The devices have been successfully used in animal behavior experiments, especially on rats.

Highly charged ion beams and their applications

NASA Astrophysics Data System (ADS)

Marler, Joan

2018-01-01

While much previous work with highly charged ions has been performed with the ions in the plasma state in which they were formed, beams of highly charged ions hold promise for exciting new experiments. Specifically low energy beams with a high degree of charge state purity are a prerequisite for momentum resolved cross section measurements and for efficient loading of highly charged ions into UHV traps for spectroscopy. The Clemson University facility is optimized for the delivery of such beams of highly charged ions with low kinetic energies. Near term experiments include energy resolved charge exchange with neutral targets.

2005-01-01

The insurance recognition of Work related Muscolo Skeletal Disorders (WMSDs) has been introduced in Italy by the sentences of Constitutional Court n. 179/1988 and 208/1988. Afterwards the National Insurance Institute against work injuries (INAIL) tried to make homogeneous, in the different INAIL regional Departments, the diagnostic protocol of the work related illness associated with repetitive manual activities. Since 1998, indeed, a clinical diagnostic protocol has been used in the different departments. This report describes the Work related Muscolo Skeletal Disorders submitted to the Apulian INAIL Regional Direction in the period 1998-2001. Among 84 cases of disease reported to the Regional Direction, 21 were recognised as professional illness, the most part of which in workers employed in services sector and mining activities. The most represented disease was carpal tunnel syndrome and it was more recurrent in men than in women, in which the first symptoms were earlier than in men. The most represented risk factor, both in reported and in recognised cases, was the presence of repetitive working movements of the upper extremities, or the combination of the previous one with other risk factors such as high frequency of working activities, postural risk, strength demand, vibrations, climatic conditions. The development of specific diagnostic criteria, the detailed job analysis and the use of specific questionnaires seem to be the main elements for the WMSDs diagnosis and for the recognition of their professional etiology.

Set-specific capture can be reduced by preemptively occupying a limited-capacity focus of attention

PubMed Central

Moore, Katherine Sledge; Weissman, Daniel H.

2011-01-01

Recent work has shown that contingent attentional capture effects can be especially large when multiple attentional sets for color guide visual search (Moore & Weissman, 2010). In particular, this research suggests that detecting a target-colored (e.g., orange) distractor leads the corresponding attentional set (e.g., identify orange letters) to enter a limited-capacity focus of attention in working memory, where it remains briefly while the distractor is being attended. Consequently, the ability to identify a differently-colored (e.g., green) target 100–300 ms later is impaired because the appropriate set (e.g., identify green letters) cannot also enter the focus of attention. In two experiments, we investigated whether such set-specific capture can be reduced by preemptively occupying the focus of attention. As predicted, a target-colored central distractor presented 233 ms before a target-colored peripheral distractor eliminated set-specific capture arising from the peripheral distractor. Moreover, this effect was observed only when the central distractor’s color (e.g., orange) (a) matched a different set than the upcoming peripheral distractor’s color (e.g., green) and (b) matched the same set as the upcoming central target’s color (e.g., orange). We conclude that the same working memory limitations that give rise to set-specific capture can be preemptively exploited to reduce it. PMID:21779149

MicroGen: a MIAME compliant web system for microarray experiment information and workflow management.

Burgarella, Sarah; Cattaneo, Dario; Pinciroli, Francesco; Masseroli, Marco

2005-12-01

Improvements of bio-nano-technologies and biomolecular techniques have led to increasing production of high-throughput experimental data. Spotted cDNA microarray is one of the most diffuse technologies, used in single research laboratories and in biotechnology service facilities. Although they are routinely performed, spotted microarray experiments are complex procedures entailing several experimental steps and actors with different technical skills and roles. During an experiment, involved actors, who can also be located in a distance, need to access and share specific experiment information according to their roles. Furthermore, complete information describing all experimental steps must be orderly collected to allow subsequent correct interpretation of experimental results. We developed MicroGen, a web system for managing information and workflow in the production pipeline of spotted microarray experiments. It is constituted of a core multi-database system able to store all data completely characterizing different spotted microarray experiments according to the Minimum Information About Microarray Experiments (MIAME) standard, and of an intuitive and user-friendly web interface able to support the collaborative work required among multidisciplinary actors and roles involved in spotted microarray experiment production. MicroGen supports six types of user roles: the researcher who designs and requests the experiment, the spotting operator, the hybridisation operator, the image processing operator, the system administrator, and the generic public user who can access the unrestricted part of the system to get information about MicroGen services. MicroGen represents a MIAME compliant information system that enables managing workflow and supporting collaborative work in spotted microarray experiment production.

Background Occupational therapists sometimes find it challenging to integrate client-centered and occupational therapy specific assessments in practice. The aim of this study was to explore the use of occupational therapy specific assessments such as the Assessment of Motor and Process Skills (AMPS) among occupational therapists in Sweden and Japan. Methods Interviews and qualitative thematic analyses were utilized. Findings Four themes are reported: (1) use it or lose it, (2) simply no space until after hours, (3) biggest barriers can be colleagues, and (4) being more specific: communication. Conclusion In keeping with previous studies, occupational therapists often find it challenging to implement client-centered and occupation-based assessment tools into practice. However, more work is needed to understand how best practices can be incorporated into a changing occupational therapy daily practice. PMID:29333112

Cognitive load theory was used to hypothesize that a general problem-solving strategy based on a make-as-many-moves-as-possible heuristic could facilitate problem solutions for transfer problems. In four experiments, school students were required to learn about a topic through practice with a general problem-solving strategy, through a conventional problem solving strategy or by studying worked examples. In Experiments 1 and 2 using junior high school students learning geometry, low knowledge students in the general problem-solving group scored significantly higher on near or far transfer tests than the conventional problem-solving group. In Experiment 3, an advantage for a general problem-solving group over a group presented worked examples was obtained on far transfer tests using the same curriculum materials, again presented to junior high school students. No differences between conditions were found in Experiments 1, 2, or 3 using test problems similar to the acquisition problems. Experiment 4 used senior high school students studying economics and found the general problem-solving group scored significantly higher than the conventional problem-solving group on both similar and transfer tests. It was concluded that the general problem-solving strategy was helpful for novices, but not for students that had access to domain-specific knowledge.

Future considerations for the use of the MRWS are also given.

Working memory capacity of biological movements predicts empathy traits.

Gao, Zaifeng; Ye, Tian; Shen, Mowei; Perry, Anat

2016-04-01

Working memory (WM) and empathy are core issues in cognitive and social science, respectively. However, no study so far has explored the relationship between these two constructs. Considering that empathy takes place based on the others' observed experiences, which requires extracting the observed dynamic scene into WM and forming a coherent representation, we hypothesized that a sub-type of WM capacity, i.e., WM for biological movements (BM), should predict one's empathy level. Therefore, WM capacity was measured for three distinct types of stimuli in a change detection task: BM of human beings (BM; Experiment 1), movements of rectangles (Experiment 2), and static colors (Experiment 3). The first two stimuli were dynamic and shared one WM buffer which differed from the WM buffer for colors; yet only the BM conveyed social information. We found that BM-WM capacity was positively correlated with both cognitive and emotional empathy, with no such correlations for WM capacity of movements of rectangles or of colors. Thus, the current study is the first to provide evidence linking a specific buffer of WM and empathy, and highlights the necessity for considering different WM capacities in future social and clinical research.

Induction of hypoxic root metabolism results from physical limitations in O 2 bioavailability in microgravity

2004-01-01

Numerous spaceflight experiments have noted changes in the roots that are consistent with hypoxia in the rootzone. These observations include general ultrastructure analysis and biochemical measurements to direct measurements of stress specific enzymes. In experiments that have monitored alcohol dehydrogenase (ADH), the data shows this hypoxically responsive gene is induced and is associated with increased ADH activity in microgravity. These changes in ADH could be induced either by spaceflight hypoxia resulting from inhibition of gravity mediated O 2 transport, or by a non-specific stress response due to inhibition of gravisensing. We tested these hypotheses in a series of two experiments. The objective of the first experiment was to determine if physical changes in gravity-mediated O 2 transport can be directly measured, while the second series of experiments tested whether disruption of gravisensing can induce a non-specific ADH response. To directly measure O 2 bioavailability as a function of gravity, we designed a sensor that mimics metabolic oxygen consumption in the rhizosphere. Because of these criteria, the sensor is sensitive to any changes in root O 2 bioavailability that may occur in microgravity. In a KC-135 experiment, the sensor was implanted in a moist granular clay media and exposed to microgravity during parabolic flight. The resulting data indicated that root O 2 bioavailability decreased in phase with gravity. In experiments that tested for non-specific induction of ADH, we compared the response of transgenic Arabidopsis plants (ADH promoted GUS marker gene) exposed to clinostat, control, and waterlogged conditions. The plants were grown on agar slats in a growth chamber before being exposed to the experimental treatments. The plants were stained for GUS activity localization, and subjected to biochemical tests for ADH, and GUS enzyme activity. These tests showed that the waterlogging treatment induced significant increases in GUS and ADH enzyme activities, while the control and clinostat treatments showed no response. This work demonstrates: (1) the inhibition of gravity-driven convective transport can reduce the O 2 bioavailability to the root tip, and (2) the perturbation of gravisensing by clinostat rotation does not induce a non-specific stress response involving ADH. Together these experiments support the microgravity convection inhibition model for explaining changes in root metabolism during spaceflight.

Confidence mediates the sex difference in mental rotation performance.

PubMed

Estes, Zachary; Felker, Sydney

2012-06-01

On tasks that require the mental rotation of 3-dimensional figures, males typically exhibit higher accuracy than females. Using the most common measure of mental rotation (i.e., the Mental Rotations Test), we investigated whether individual variability in confidence mediates this sex difference in mental rotation performance. In each of four experiments, the sex difference was reliably elicited and eliminated by controlling or manipulating participants' confidence. Specifically, confidence predicted performance within and between sexes (Experiment 1), rendering confidence irrelevant to the task reliably eliminated the sex difference in performance (Experiments 2 and 3), and manipulating confidence significantly affected performance (Experiment 4). Thus, confidence mediates the sex difference in mental rotation performance and hence the sex difference appears to be a difference of performance rather than ability. Results are discussed in relation to other potential mediators and mechanisms, such as gender roles, sex stereotypes, spatial experience, rotation strategies, working memory, and spatial attention.

Connecting Arctic/Antarctic Researchers and Educators (CARE): Supporting Teachers and Researchers Beyond the Research Experience

2007-12-01

Teacher research experiences (TREs) require long-term sustained support for successful transfer of research experiences into the classroom. Specifically, a support mechanism that facilitates focused discussion and collaboration among teachers and researchers is critical to improve science content and pedagogical approaches in science education. Connecting Arctic/Antarctic Researchers and Educators (CARE) is a professional development network that utilizes online web meetings to support the integration of science research experiences into classroom curriculum. CARE brings together teachers and researchers to discuss field experiences, current science issues, content, technology resources, and pedagogy. CARE is a component of the Arctic Research Consortium of the U.S. (ARCUS) education program PolarTREC--Teachers and Researchers Exploring and Collaborating. PolarTREC is a three-year (2007-2009) teacher professional development program celebrating the International Polar Year (IPY) that advances polar science education by bringing K-12 educators and polar researchers together in hands-on field experiences in the Arctic and Antarctic. Currently in its second year, the program fosters the integration of research and education to produce a legacy of long-term teacher-researcher collaborations, improved teacher content knowledge through experiences in scientific inquiry, and broad public interest and engagement in polar science. The CARE network was established to develop a sustainable learning community through which teachers and researchers will further their work to bring polar research into classrooms. Through CARE, small groups of educators are formed on the basis of grade-level and geographic region; each group also contains a teacher facilitator. Although CARE targets educators with previous polar research experiences, it is also open to those who have not participated in a TRE but who are interested in bringing real-world polar science to the classroom. Researchers are regularly invited to attend the web meetings, and some CARE meetings host specific researchers to talk about their work and their experiences working with teachers in the field. Facilitated group meetings focus on discussions of field experiences, current scientific research, and application of experiences to classrooms and curriculum. CARE is designed to be mindful of participants' needs; the meeting agendas reflect the stated concerns of participating teachers and researchers, such as incorporating real data into everyday curriculum, teaching about the impacts of climate change in a meaningful and educational way, developing polar related lessons and units that include State and National standards, and incorporating scientific tools and instruments into everyday curriculum. In addition to the regularly scheduled CARE group meetings, a series of CARE Seminars will be held in spring 2008 and open to the public. The public CARE Seminars will focus on issues that are of interest to a wider range of educators (e.g. clues from past climates, impacts of climate change on the Arctic, cultural sensitivity and working with indigenous peoples, and women and minorities of polar science. CARE provides a mechanism for teachers and researchers to interact, leveraging their diverse experiences and expertise to form long-term professional relationships that continue beyond the research experience.

Musical Experience, Sensorineural Auditory Processing, and Reading Subskills in Adults.

PubMed

Tichko, Parker; Skoe, Erika

2018-04-27

Developmental research suggests that sensorineural auditory processing, reading subskills (e.g., phonological awareness and rapid naming), and musical experience are related during early periods of reading development. Interestingly, recent work suggests that these relations may extend into adulthood, with indices of sensorineural auditory processing relating to global reading ability. However, it is largely unknown whether sensorineural auditory processing relates to specific reading subskills, such as phonological awareness and rapid naming, as well as musical experience in mature readers. To address this question, we recorded electrophysiological responses to a repeating click (auditory stimulus) in a sample of adult readers. We then investigated relations between electrophysiological responses to sound, reading subskills, and musical experience in this same set of adult readers. Analyses suggest that sensorineural auditory processing, reading subskills, and musical experience are related in adulthood, with faster neural conduction times and greater musical experience associated with stronger rapid-naming skills. These results are similar to the developmental findings that suggest reading subskills are related to sensorineural auditory processing and musical experience in children.

In this editorial, it is strongly advocated that a change of policy is warranted in order to prevent neuroscience from becoming a waste of time and money in the 21st century. Repeating the same trick in different patient populations and perusing the scientific literature seems to currently be the backbone of medical science. However, this approach does not provide knowledge on how the brain works or how specific dysfunctions result in specific diseases. Therefore, earlier findings should, first, be combined to develop new theories on the mechanics of the mind, and, second, these new ideas should be tested in well-designed experiments.

Women's experiences of developing musculoskeletal diseases: employment challenges and policy recommendations.

Crooks, Valorie A

2007-07-30

To answer three specific questions: (i) How do women experience the workplace after the onset of a musculoskeletal disease; (ii) What employment policy and programme suggestions can they offer for ways to better support chronically ill women in their abilities to maintain workforce participation; and (iii) How are these women's employment policy and programme recommendations informed by their own lived experiences and desires? In-depth interviews were conducted with 18 women who had developed musculoskeletal diseases while involved in the labour market. Data were coded and analysed thematically. Participants identified three common workplace barriers experienced and three types of workplace accommodations commonly requested. They offered four specific employment policy and programme recommendations for ways to better support women who develop musculoskeletal diseases in maintaining labour market participation. It is found that their employment policy and programme recommendations are informed by their own experiences in the workplace and desires for being supported in maintaining involvement in paid labour. Creating employment programmes and policies that support chronically ill women in their attempts to remain involved in the workforce based on how much paid labour they are able to perform and where they are best able to work is of the utmost importance.

Use of family-friendly work arrangements and work-family conflict: Crossover effects in dual-earner couples.

Schooreel, Tess; Verbruggen, Marijke

2016-01-01

This study uses a dyadic approach to examine how an employee's work-family conflict is affected when his or her partner makes use of family-friendly work arrangements. We focused on 2 types of family-friendly practices, that is, reduced work hours and schedule or workplace flexibility. Hypotheses were tested with multilevel structural equation modeling using information of 186 dual-earner couples. In line with our hypotheses, we found support for both a positive and a negative crossover effect, though the results showed differences between the 2 types of family-friendly work arrangements. First, a positive crossover effect was found for both reduced work hours and schedule or workplace flexibility; however, the specific mechanisms explaining this effect differed per type of arrangements. In particular, employees whose partner made use of reduced work hours were found to experience less home demands, which was in turn associated with lower family-to-work conflict, whereas employees whose partner made use of schedule or workplace flexibility experienced a similar positive crossover effect but through an increase in the social support they perceived. Second, a negative crossover effect was found only for reduced work hours and not for schedule or workplace flexibility. Specifically, employees whose partner made use of reduced work hours were found to work on average more hours a week, which was in turn related with more work-to-family conflict, whereas employees whose partner made use of schedule or workplace flexibility worked on average fewer hours a week and consequently experienced lower work-to-family conflict. Implications for literature and practice are discussed. (c) 2016 APA, all rights reserved).

Cyders, Melissa A; VanderVeen, J Davis; Plawecki, Martin; Millward, James B; Hays, James; Kareken, David A; O'Connor, Sean

2016-02-01

Although negative mood has long been implicated in differences in alcohol seeking by men and women, little research has used precise, well-controlled laboratory experiments to examine how negative mood affects alcohol-seeking behaviors. A total of 34 (19 women) community-dwelling, alcohol-using adults aged 21 to 32 (mean age = 24.86, SD = 3.40, 74.3% Caucasian; Alcohol Use Disorders Identification Test [AUDIT] = 10.1, SD = 3.4) completed 2 counterbalanced intravenous alcohol self-administration sessions: one under negative mood and one under neutral mood. Fourteen individuals (9 women; mean age = 25.00, SD = 2.77) participated in an alcohol "liking" experiment (i.e., free access [FA] drinking) and 20 individuals (10 women; mean age = 24.77, SD = 3.73) participated in an alcohol "wanting" experiment, in which gaining access to alcohol required progressively effortful work. There was no significant difference between men and women on the AUDIT, t(32) = -0.38, p = 0.71. Priming with negative mood induction caused a significant decrease in self-reported mood (mean change = -1.85, t(32) = -6.81, p < 0.001), as intended. In FA, negative mood was associated with a significantly increased peak breath alcohol concentration (BrAC; F = 9.41, p = 0.01), with a trend toward a greater effect in men than in women (F = 2.67, p = 0.13). Negative mood also had a significant effect on peak BrAC achieved in the progressive work paradigm (F = 5.28, p = 0.04), with a significantly stronger effect in men (F = 5.35, p = 0.03) than women; men also trended toward more consistent work for alcohol across both neutral and negative sessions. These preliminary findings demonstrate a gender-specific response on how mood affects alcohol seeking and suggest gender-specific interventions to prevent mood-based alcohol consumption.

This paper reports the second part of an exploratory study into occupational therapists' and physiotherapists' perceptions and experiences of teamwork in neurological rehabilitation: the factors that were thought to influence effective and ineffective teamwork, and the meaning behind effective and ineffective teamwork in neurological rehabilitation. The study was undertaken through semi-structured interviews of 10 therapists from three different neurological rehabilitation teams based in the United Kingdom, and used the critical incident technique. Through analysis of the data, several main themes emerged regarding the perceived critical happenings in effective and ineffective teamwork. These were: team events and characteristics, team members' characteristics, shared and collaborative working practices, communication, specific organizational structures, environmental, external, and patient and family-related factors. Effective and ineffective team-work was perceived to impact on a number of levels: having implications for the team, the patient, individual team members, and the neurological rehabilitation service. The study supported the perceived value of team work within neurological rehabilitation. It also indicated the extensive and variable factors that may influence the team-working process as well as the complex and diverse nature of the process.
