2018-02-01

Previous research has shown that the medial temporal lobes (MTL) are more strongly engaged when individuals think about the future than about the present, leading to the suggestion that future projection drives MTL engagement. However, future thinking tasks often involve scene processing, leaving open the alternative possibility that scene-construction demands, rather than future projection, are responsible for the MTL differences observed in prior work. This study explores this alternative account. Using functional magnetic resonance imaging, we directly contrasted MTL activity in 1) high scene-construction and low scene-construction imagination conditions matched in future thinking demands and 2) future-oriented and present-oriented imagination conditions matched in scene-construction demands. Consistent with the alternative account, the MTL was more active for the high versus low scene-construction condition. By contrast, MTL differences were not observed when comparing the future versus present conditions. Moreover, the magnitude of MTL activation was associated with the extent to which participants imagined a scene but was not associated with the extent to which participants thought about the future. These findings help disambiguate which component processes of imagination specifically involve the MTL. Published by Oxford University Press 2016.

Factors influencing patient safety in Sweden: perceptions of patient safety officers in the county councils

PubMed Central

2013-01-01

Background National, regional and local activities to improve patient safety in Sweden have increased over the last decade. There are high ambitions for improved patient safety in Sweden. This study surveyed health care professionals who held key positions in their county council’s patient safety work to investigate their perceptions of the conditions for this work, factors they believe have been most important in reaching the current level of patient safety and factors they believe would be most important for achieving improved patient safety in the future. Methods The study population consisted of 218 health care professionals holding strategic positions in patient safety work in Swedish county councils. Using a questionnaire, the following topics were analysed in this study: profession/occupation; number of years involved in a designated task on patient safety issues; knowledge/overview of the county council’s patient safety work; ability to influence this work; conditions for this work; and the importance of various factors for current and future levels of patient safety. Results The response rate to the questionnaire was 79%. The conditions that had the highest number of responses in complete agreement were “patients’ involvement is important for patient safety” and “patient safety work has good support from the county council’s management”. Factors that were considered most important for achieving the current level of patient safety were root cause and risk analyses, incident reporting and the Swedish Patient Safety Law. An organizational culture that encourages reporting and avoids blame was considered most important for improved patient safety in the future, closely followed by improved communication between health care practitioners and patients. Conclusion Health care professionals with important positions in the Swedish county councils’ patient safety work believe that conditions for this work are somewhat constrained. They attribute the current levels of patient safety to a broad range of factors and believe that many different solutions can contribute to enhanced patient safety in the future, suggesting that this work must be multifactorial.

Reid, D H; Parsons, M B; Green, C W

1998-01-01

We evaluated a prework assessment for predicting work-task preferences among workers with severe multiple disabilities prior to beginning supported work. The assessment involved comparing worker selections from pairs of work tasks drawn from their future job duties. Results of workers' choices once they began their jobs in a publishing company indicated that the assessment predicted tasks that the workers preferred to work on during their job routines. Results are discussed regarding other possible means of determining preferred types of supported work.

Service Users' Involvement and Engagement in Interprofessional Care.

PubMed

Kaini, B K

2016-01-01

Interprofessional care is joint working between health care professionals by pooling their skills, knowledge and expertise, to make joint decisions and learn from each other for the benefits of service users and healthcare professionals. Service users involvement is considered as one of the important aspects of planning, management and decision making process in the delivery of health care to service users. Service users' involvement is not the same as public involvement and partnership arrangements in health care. The active involvement and engagement of service users in health care positively contributes to improve quality of care, to promote better health and to shape the future of health services. Service users are always at the centre of health care professionals' values, work ethics and roles. Moreover, service users centred interprofessional team collaboration is very important to deliver effective health services.

A model of involvement in work-related learning and development activity: the effects of individual, situational, motivational, and age variables.

PubMed

Maurer, Todd J; Weiss, Elizabeth M; Barbeite, Francisco G

2003-08-01

Eight hundred employees from across the U.S. work force participated in a detailed 13-month longitudinal study of involvement in learning and development activities. A new model was posited and tested in which the hypothesized sequence was as follows: worker age --> individual and situational antecedents --> perceived benefits of participation and self-efficacy for development --> attitudes toward development --> intentions to participate --> participation. The results depict a person who is oriented toward employee development as having participated in development activities before, perceiving themselves as possessing qualities needed for learning, having social support for development at work and outside of work, being job involved, having insight into his or her career, and believing in the need for development, in his or her ability to develop skills and to receive intrinsic benefits from participating. Given the aging work force, a detailed treatment of age differences in development is presented. Implications for new ideas in practice and future research are discussed.

Differences between early and late involvement of palliative home care in oncology care: A focus group study with palliative home care teams.

To date, no randomised controlled trials on the integration of specialised palliative home care into oncology care have been identified. Information on whether existing models of integrated care are applicable to the home care system and how working procedures and skills of the palliative care teams might require adaptation is missing. To gain insight into differences between early and late involvement and the effect on existing working procedures and skills as perceived by palliative home care teams. Qualitative study - focus group interviews. Six palliative home care teams in Flanders, Belgium. Participants included physicians, nurses and psychologists. Differences were found concerning (1) reasons for initiation, (2) planning of care process, (3) focus on future goals versus problems, (4) opportunity to provide holistic care, (5) empowerment of patients and (6) empowerment of professional caregivers. A shift from a medical approach to a more holistic approach is the most noticeable. Being involved earlier also results in a more structured follow-up and in empowering the patient to be part of the decision-making process. Early involvement creates the need for transmural collaboration, which leads to the teams taking on more supporting and coordinating tasks. Being involved earlier leads to different tasks and working procedures and to the need for transmural collaboration. Future research might focus on the development of an intervention model for the early integration of palliative home care into oncology care. To develop this model, components of existing models might need to be adapted or extended.

Predicting Future Commitment to Care for Frail Parents Among Employed Caregivers.

PubMed

Lechner, Viola M

1992-06-01

A study of 133 full time employees with parent care responsibilities investigated various factors that could reduce this group's future caregiving commitment to aging parents. Study factors included: caregiver attributes, level of caregiving involvement, job stress, tensions between the caregiver and the dependent parent, caregiver's level of physical and mental strain, and limited support from family and friends. The relationship between the caregiver and the parent was the best predictor of sustained commitment to caregiving. One aspect of the employees' work experience made a small, but important contribution to respondents' future care plans. Those employees who frequently adjusted their work schedule and routine to accommodate parent care demands were less likely to sustain their caregiving commitment. Reasons for these findings are explored and implications for social policy and clinical practice are discussed.

2011-01-01

We describe Mexican American 7th graders’ expectations for future work and family roles and investigate links between patterns of future expectations and adolescents’ cultural experiences and adjustment. Adolescents participated in home interviews and a series of seven nightly phone calls. Five unique patterns of adolescents’ future expectations were identified (N = 246): Career Oriented, Independent, Family Oriented, Early, and Inconsistent. Career Oriented adolescents had the highest socioeconomic status and contact with the U.S. (e.g., generation status) whereas Family Oriented adolescents had the lowest. Cultural orientations, values, and involvement also varied across groups. For example, Career Oriented adolescents reported significantly higher familism values compared to Inconsistent adolescents. Clusters also differed on adjustment: Career Oriented and Family Oriented adolescents reported higher parental warmth and less risky behavior compared to Independent and Inconsistent adolescents. Findings underscore the multi-faceted nature of adolescents’ future expectations and the diversity in cultural experiences among Mexican origin youth. PMID:23338812

Sabey, Abby; Hardy, Holly

2013-09-01

Expectations of the latest manifestation of GPled commissioning, in delivering cost-savings and improved services, are considerable. However, previous models suggest clinical engagement and other factors may hinder its success. It is timely to explore the views of the newest generation of GPs about involvement in commissioning, to inform plans for preparing the future workforce. To explore the views of recently qualified GPs about their future role in commissioning health services. A qualitative study with GPs qualifying with Severn Deanery between 2007 and 2010. Semi-structured interviews with 18 GPs between November 2011 and April 2012. These GPs lack understanding of roles and skills required for commissioning. Readiness is related to experience as a GP and of how services are financed and run, making timeliness for becoming involved important. Not all GPs feel motivated for commissioning and readiness is further hindered by feelings of conflict and uncertainty about how commissioning will work. There is optimism around working differently and better representing patients, but caution around risks and for some, cynicism about motives, will need addressing. While there is some optimism among these GPs about representing patients, leading reform and working differently with colleagues, there are concerns. GPs need to better understand the processes involved, experience and skills needed, and roles they can take. They can be helped through education and mentoring by established GPs to be ready for a role in commissioning.

Shaping the future: reforming routine emergency nursing work.

PubMed

Sbaih, L C

2001-10-01

The provision of emergency care, for many A&E nurses, is dependent upon taken-for-granted assumptions, associated with the ongoing management of the changing shape of the work. In particular, routine working practices and procedures reflect a collective ideology of A&E nursing labour which involves moving people on and out of the emergency department. Subscribing to this ideology and realizing good shape provides nurses with a feeling that they are in control of their work and have done a good job. Analysis of the NHS Plan has identified that the Government's goals for reform support as well as challenge the ways in which nurses currently strive towards maintaining the good shape of their work. In particular, the ideology of patient-centredness and the Chief Nursing Officer's ten key roles for nurses, provide an opportunity for nurses to explore the ways in which they can cultivate their routine activities and contribute to the shape of future emergency nursing work.

Butts, Marcus M; Vandenberg, Robert J; DeJoy, David M; Schaffer, Bryan S; Wilson, Mark G

2009-04-01

This study sought to understand how high involvement work processes (HIWP) are processed at the employee level. Using structural equation modeling techniques, the authors tested and supported a model in which psychological empowerment mediated the effects of HIWP on job satisfaction, organizational commitment, job performance, and job stress. Furthermore, perceived organizational support (POS) was hypothesized to moderate the relationships between empowerment and these outcomes. With exception for the empowerment-job satisfaction association, support was found for our predictions. Future directions for research and the practical implications of our findings for both employees and organizations are discussed.

Psychosocial Working Conditions and Cognitive Complaints among Swedish Employees

Stenfors, Cecilia U. D.; Magnusson Hanson, Linda; Oxenstierna, Gabriel; Theorell, Töres; Nilsson, Lars-Göran

2013-01-01

Background Cognitive complaints involving problems with concentration, memory, decision-making and thinking are relatively common in the work force. The sensitivity of both subjective and objective cognitive functioning to common psychiatric conditions, stress levels and to cognitive load makes it plausible that psychosocial working conditions play a role in cognitive complaints. Thus, this study aimed to test the associations between psychosocial work factors and cognitive complaints in nationally representative samples of the Swedish work force. Cross-sectional (n = 9751) and prospective (n = 3644; two time points two years apart) sequential multiple regression analyses were run, adjusting for general confounders, depressive- and sleeping problems. Additional prospective analyses were run adjusting for baseline cognitive complaints. Cross-sectional results High quantitative demands, information and communication technology (ICT) demands, underqualification and conflicts were positively associated with cognitive complaints, while social support, good resources at work and overqualification were negatively associated with cognitive complaints in all models. Skill discretion and decision authority were weakly associated with cognitive complaints. Conflicts were more strongly associated with cognitive complaints in women than in men, after adjustment for general confounders. Prospective results Quantitative job demands, ICT demands and underqualification were positively associated with future cognitive complaints in all models, including when adjusted for baseline cognitive complaints. Decision authority was weakly positively associated with future cognitive complaints, only after adjustment for depressive- and sleeping problems respectively. Social support was negatively associated with future cognitive complaints after adjustment for general confounders and baseline cognitive complaints. Skill discretion and resources were negatively associated with future cognitive complaints after adjustment for general confounders. The associations between quantitative demands and future cognitive complaints were stronger in women. Discussion/Conclusions The findings indicate that psychosocial working conditions should be taken into account when considering cognitive complaints among employees. PMID:23560101

The overall project RehaFutur, which has been initiated and funded by the Federal Ministry of Labour and Social Affairs and which involves all the actors of the vocational rehabilitation system, is aimed at advancing the development of the vocational rehabilitation system, so as to prepare it for the challenges ahead. The project started with a group of scientific experts, who formulated 8 fields of action for further developing the vocational rehab system. On this basis, 4 working groups were set up in the framework of a development project to elaborate concrete recommendations on how to implement the necessary changes in vocational rehabilitation. The topics dealt with by the working groups were "self-determination and self-responsibility", "regulation of the overall process", "occupation and working environment" as well as "research". The process was supervised by a steering group, the results were moreover discussed in workshops. Recommendations have been made for 10 subject areas: "consultation and information", "joint service points", "use of the internet", "quality assurance", "individualisation and greater flexibility", "orientation towards the working environment", "participation of the beneficiaries", "research", "legislation", "cooperation of the actors". The next step of the RehaFutur overall project is implementation of those recommendations. This needs to be done in an interdisciplinary manner and conjointly by the agencies and providers involved, including the beneficiaries as experts. As different framework conditions have to be taken into account, the process is a complex one and needs to be supported by systematic research. © Georg Thieme Verlag KG Stuttgart · New York.

The Manhattan Engineer District (MED) and U.S. Atomic Energy Commission (AEC) contracted for support work through private and academic parties through the early 1960's. The work often involved radioactive materials. Residual radioactive contamination was left at some of more than 600 potentially contaminated (candidate) sites, and worker health and safety concerns remain from the site operations and subsequent remediation activities. The U.S. Department of Energy (DOE) initiated a program to identify and protect records of MED/AEC activities and of remediation work conducted under the Formerly Utilized Sites Remedial Action Program (FUSRAP) to aid in resolving questions about site conditions, liability,more » and worker health and safety and to ensure ongoing protectiveness of human health and the environment. This paper discusses DOE activities undertaken to locate records collections, confirm retention schedules and access requirements, and document information about the collections for use by future stewards. In conclusion: DOE-LM recognizes that records and information management is a critical component of effective LTS and M. Records are needed to answer questions about site conditions and demonstrate to the public in the future that the sites are safe. DOE-LM is working to satisfy present needs and anticipate future uses for FUSRAP records, and compile a collection of site and program information from which future stewards can readily locate and retrieve needed information.

Pensions, tax and the anaesthetist: significant implications for workforce planning.

PubMed

Pandit, J J

2016-08-01

This paper shows how recent tax changes to pensions (i.e. new lifetime and annual allowance contribution limits) mean that NHS consultants will need to adopt one of four rational strategies to work and financial planning. Two of those strategies (termed 'Earn Fast, Drop Out' and 'Never Enter') involve a break between work and pensions. The logical consequence of this break is that consultants may exercise options to maximise their total income, which in turn will result in less work within the NHS and more work in alternative higher paying (e.g. private) sectors. A third strategy ('Go Slow, Stay Low') also involves less-than-full-time NHS work. Only one option ('Do Nothing' as a result of the tax changes) has no effect. In short, the tax changes will predictably lead to future senior consultants devoting proportionately much less of their time to NHS work than before. The article discusses the important implications of this conclusion for NHS workforce planning. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

The effect of alternative work arrangements on women's well-being: a demand-control model.

PubMed

Kelloway, E K; Gottlieb, B H

1998-01-01

The growth of women's participation in the labor force and evidence of the conflict they experience between job and family demands have spurred many employers to introduce alternative work arrangements such as flextime, job sharing, and telecommuting. Drawing on data gained from a sample of women (N = 998) in two large Canadian organizations, this study evaluates two mediational models of the impact of alternative work arrangements on women's stress and family role competence. Specifically, it tests and finds support for the hypotheses that (a) work arrangements involving scheduling flexibility (telecommuting and flextime) promote these aspects of women's well-being by increasing their perceived control over their time, and (b) arrangements involving reduced hours of employment (part-time employment and job sharing) promote well-being by reducing perceived job overload. Discussion of these findings centers on their implications for employed women, their employers, and future research.

2001-05-01

The effects of adverse work environments were examined in the context of other risk/protective factors in this extension of a short-term longitudinal study involving 184 newly appointed women teachers. Regression analyses revealed that-adjusting for preemployment levels of the outcomes and negative affectivity-social support and adversity in the fall work environment were among the factors that affected spring depressive symptoms, self-esteem, job satisfaction, and motivation to teach. Support from nonwork sources was directly related to future improved symptom levels and self-esteem; supervisor and colleague support were directly related to future job satisfaction. Effects of occupational coping, professional efficacy, locus of control, and school factors (e.g., special vs. regular education) were largely nonsignificant. Structural equation analyses indicated that adverse working conditions began to seriously affect the women soon after they started teaching.

Ethical aspects of limiting residents' work hours.

PubMed

Wiesing, Urban

2007-09-01

The regulation of residents' work hours involves several ethical conflicts which need to be systematically analysed and evaluated. ARGUMENTS AND CONCLUSION: The most important ethical principle when regulating work hours is to avoid the harm resulting from the over-work of physicians and from an excessive division of labour. Additionally, other ethical principles have to be taken into account, in particular the principles of nonmaleficence and beneficence for future patients and for physicians. The article presents arguments for balancing the relevant ethical principles and analyses the structural difficulties that occur unavoidably in any regulation of the complex activities of physicians.

Using health technology assessment to identify gaps in evidence and inform study design for comparative effectiveness research.

PubMed

Tunis, Sean R; Turkelson, Charles

2012-12-01

Health technology assessment (HTA) is primarily used as a tool to ensure that clinical and policy decisions are made with the benefit of a systematic analysis of all completed research. This article describes the progress and potential for HTA reports to improve the quality and relevance of future research and to better serve the information needs of patients, clinicians, payers, and other decision makers. We conducted a review of the current published literature and working papers describing past, ongoing, and future initiatives that rely on HTA reports to identify gaps in evidence and improve the design of future research. Although still in a developmental stage, significant progress is under way to improve methods for using HTA reports for the systematic identification of research gaps, prioritization of future research, and improvement of study designs. Several well-defined frameworks have been developed to assist those who produce HTA to become more effective in these additional domains of work. A recurring element of this work is the importance of meaningfully involving stakeholders in the process of defining future research needs and designing studies to address them. Patients, clinicians, and payers are important audiences for completed research and are now recognized as serving an important role in determining what future research is needed. There are substantial opportunities to improve the quality, relevance, and efficiency of clinical research. Recent efforts are beginning to demonstrate the potential to build on the work invested in developing HTA reports to provide a roadmap toward these objectives.

Clinical placements and nursing students' career planning: a qualitative exploration.

PubMed

McKenna, Lisa; McCall, Louise; Wray, Natalie

2010-04-01

Many nursing students enter undergraduate programmes with preconceived ideas about their future nursing careers, and intend to practice in particular areas such as midwifery or paediatrics. Through clinical placements, students are exposed to different clinical areas and professional socialization is facilitated. However, little is known about the influence of clinical placements on students' career intentions. This paper reports nursing findings drawn from a large qualitative study conducted in Victoria, Australia that sought to explore the influence of health professional students' clinical placements on their future career intentions. Participants were invited to be involved in either face-to-face or focus group interviews depending upon their own preference. Thematic data analysis revealed three main themes: 're-affirming career choice', 'working in a particular area' and 'work location'. Findings from the study add to our understanding of factors influencing nursing students' planning for their future careers including the impact of clinical placements.

Future exploration missions will dictate a level of autonomy never before experienced in human spaceflight. Mission plans involving the uncrewed phases of complex human spacecraft in deep space will require a coordinated autonomous capability to be able to maintain the spacecraft when ground control is not available. One promising direction involves embedding intelligence into the system design both through the employment of state-of-the-art system engineering principles as well as through the creation of a cognitive network between a smart spacecraft or habitat and embodiments of cognitive agents. The work described here details efforts to integrate IBM's Watson and other cognitive computing services into NASA Johnson Space Center (JSC)'s Robonaut 2 (R2) anthropomorphic robot. This paper also discusses future directions this work will take. A cognitive spacecraft management system that is able to seamlessly collect data from subsystems, determine corrective actions, and provide commands to enable those actions is the end goal. These commands could be to embedded spacecraft systems or to a set of robotic assets that are tied into the cognitive system. An exciting collaboration with Woodside provides a promising Earth-bound testing analog, as controlling and maintaining not normally manned off-shore platforms have similar constraints to the space missions described.

Objectives To identify the shared priorities for future research of women affected by and clinicians involved with pessary use for the management of prolapse. Design A priority setting project using a consensus method. Setting A James Lind Alliance Pessary use for prolapse Priority Setting Partnership (JLA Pessary PSP) conducted from May 2016 to September 2017 in the UK. Participants The PSP was run by a Steering Group of three women with experience of pessary use, three experienced clinicians involved with management of prolapse, two researchers with relevant experience, a JLA adviser and a PSP leader. Two surveys were conducted in 2016 and 2017. The first gathered questions about pessaries, and the second asked respondents to prioritise a list of questions. A final workshop was held on 8 September 2017 involving 10 women and 13 clinician representatives with prolapse and pessary experience. Results A top 10 list of priorities for future research in pessary use for prolapse was agreed by consensus. Conclusions Women with experience of pessary use and clinicians involved with prolapse management have worked together to determine shared priorities for future research. Aligning the top 10 results with existing research findings will highlight the gaps in current evidence and signpost future research to areas of priority. Effective dissemination of the results will enable research funding bodies to focus on gathering the evidence to answer the questions that matter most to those who will be affected. PMID:29705767

An inferential and descriptive statistical examination of the relationship between cumulative work metrics and injury in Major League Baseball pitchers.

PubMed

Karakolis, Thomas; Bhan, Shivam; Crotin, Ryan L

2013-08-01

In Major League Baseball (MLB), games pitched, total innings pitched, total pitches thrown, innings pitched per game, and pitches thrown per game are used to measure cumulative work. Often, pitchers are allocated limits, based on pitches thrown per game and total innings pitched in a season, in an attempt to prevent future injuries. To date, the efficacy in predicting injuries from these cumulative work metrics remains in question. It was hypothesized that the cumulative work metrics would be a significant predictor for future injury in MLB pitchers. Correlations between cumulative work for pitchers during 2002-07 and injury days in the following seasons were examined using regression analyses to test this hypothesis. Each metric was then "binned" into smaller cohorts to examine trends in the associated risk of injury for each cohort. During the study time period, 27% of pitchers were injured after a season in which they pitched. Although some interesting trends were noticed during the binning process, based on the regression analyses, it was found that no cumulative work metric was a significant predictor for future injury. It was concluded that management of a pitcher's playing schedule based on these cumulative work metrics alone could not be an effective means of preventing injury. These findings indicate that an integrated approach to injury prevention is required. This approach will likely involve advanced cumulative work metrics and biomechanical assessment.

How to Get Successfully Involved with K-12 Education

NASA Astrophysics Data System (ADS)

Duncan, D.; Fraknoi, A.; Bennett, M.

1998-05-01

Many astronomers now have some involvement in K-12 education, either through their children, through large projects with an education or outreach office, or through an educational component to their own grants. Some may need to incorporate education components into future proposals. For those new to education, it can be difficult to decide how best to use their limited resources without "re-inventing the wheel." Some astronomers are comfortable taking a direct role in the classroom or working with teachers, others prefer developing web-based or printed materials, while still others wouldrather work with local schools of education to enhance the training of future teachers. Which of these roles is most useful? In this session, participants will learn what has worked well in the past, with special attention paid to ways in which astronomers' and physicists' training and instincts may fail them when working in education. Invited teachers will describe their classrooms and how astronomers can be most helpful to them. Sample (successful) activities will be demonstrated, and information given about the wide range of existing astronomy and space-science education programs around the country. A full menu of useful ways that astronomers can get involved will be presented, as well as the organizations and institutions which can help in devising a meaningful education program. Handouts will include a catalog of national astronomy education projects, a list of educational web sites, information about the NASA OSS education brokers and facilitators, examples of successful educational materials, and a listing of roles astronomers have played or could play to enhance K-12 education.

Turning attention to clinician engagement in Victoria.

Jorm, Christine; Hudson, Robyn; Wallace, Euan

2017-11-16

The engagement of clinicians with employing organisations and with the broader health system results in better safer care for patients. Concerns about the adequacy of clinician engagement in the state of Victoria led the Victorian Department of Health and Human Services to commission a scoping study. During this investigation more than 100 clinicians were spoken with and 1800 responded to surveys. The result was creation of a clear picture of what engagement and disengagement looked like at all levels - from the clinical microsystem to state health policy making. Multiple interventions are possible to enhance clinician engagement and thus the care of future patients. A framework was developed to guide future Victorian work with four elements: setting the agenda, informing, involving and empowering clinicians. Concepts of work or employee engagement that are used in other industries don't directly translate to healthcare and thus the definition of engagement chosen for use centred on involvement. This was designed to encourage system managers to ensure clinicians are full participants in design, planning and evaluation and in all decisions that affect them and their patients.

Lange, Kevin E.; Perka, Alan T.; Duffield, Bruce E.; Jeng, Frank F.

2005-01-01

The selection of spacecraft and space suit atmospheres for future human space exploration missions will play an important, if not critical, role in the ultimate safety, productivity, and cost of such missions. Internal atmosphere pressure and composition (particularly oxygen concentration) influence many aspects of spacecraft and space suit design, operation, and technology development. Optimal atmosphere solutions must be determined by iterative process involving research, design, development, testing, and systems analysis. A necessary first step in this process is the establishment of working bounds on the atmosphere design space.

This paper identifies and bounds the problem, describes the need to extend Space Link services, gives an overview of the operations concept, and introduces complimentary CCSDS work on standardizing Space Link Extension services.

The public hospital of the future.

PubMed

Zajac, Jeffrey D

2003-09-01

Public hospitals designed for the past are not changing rapidly enough to meet the needs of the future. Changing work practices, increased pressure on bed occupancy, and greater numbers of patients with complex diseases and comorbidities will determine the functions of future hospitals. To maximise the use of resources, hospital "down times" on weekends and public holidays will be a distant memory. Elective surgery will increase in the traditionally "quiet times", such as summer, and decrease in the busy winter period. The patient will be the focus of an efficient information flow, streamlining patient care in hospital and enhancing communication between hospitals and community-based health providers. General and specialty units will need to work more efficiently together, as general physicians take on the role of patient case managers for an increasing proportion of patients. Funding needs to be adequate, and system management should involve clinicians. Safety will be enshrined in hospital systems and procedures, as well as in the minds of hospital staff. If these changes are not implemented successfully, public hospitals will not survive in the future.

Ideals, practices, and future prospects of stakeholder involvement in sustainability science

Vermaßen, Hannah; Ellenbeck, Saskia

2017-01-01

This paper evaluates current stakeholder involvement (SI) practices in science through a web-based survey among scholars and researchers engaged in sustainability or transition research. It substantiates previous conceptual work with evidence from practice by building on four ideal types of SI in science. The results give an interesting overview of the varied landscape of SI in sustainability science, ranging from the kinds of topics scientists work on with stakeholders, over scientific trade-offs that arise in the field, to improvements scientists wish for. Furthermore, the authors describe a discrepancy between scientists’ ideals and practices when working with stakeholders. On the conceptual level, the data reflect that the democratic type of SI is the predominant one concerning questions on the understanding of science, the main goal, the stage of involvement in the research process, and the science–policy interface. The fact that respondents expressed agreement to several types shows they are guided by multiple and partly conflicting ideals when working with stakeholders. We thus conclude that more conceptual exchange between practitioners, as well as more qualitative research on the concepts behind practices, is needed to better understand the stakeholder–scientist nexus.

To identify the shared priorities for future research of women affected by and clinicians involved with pessary use for the management of prolapse. A priority setting project using a consensus method. A James Lind Alliance Pessary use for prolapse Priority Setting Partnership (JLA Pessary PSP) conducted from May 2016 to September 2017 in the UK. The PSP was run by a Steering Group of three women with experience of pessary use, three experienced clinicians involved with management of prolapse, two researchers with relevant experience, a JLA adviser and a PSP leader. Two surveys were conducted in 2016 and 2017. The first gathered questions about pessaries, and the second asked respondents to prioritise a list of questions. A final workshop was held on 8 September 2017 involving 10 women and 13 clinician representatives with prolapse and pessary experience. A top 10 list of priorities for future research in pessary use for prolapse was agreed by consensus. Women with experience of pessary use and clinicians involved with prolapse management have worked together to determine shared priorities for future research. Aligning the top 10 results with existing research findings will highlight the gaps in current evidence and signpost future research to areas of priority. Effective dissemination of the results will enable research funding bodies to focus on gathering the evidence to answer the questions that matter most to those who will be affected. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

To assess pharmacy student involvement in leadership and service roles and to evaluate the association between admissions data and student involvement. Doctor of pharmacy (PharmD) students were invited to complete a 56-item online survey instrument containing questions regarding leadership and service involvement, work experiences, perceived contribution of involvement to skill development, and perceived importance of involvement. Responses were linked to admissions data to identify possible associations. Five hundred fourteen (82.4%) pharmacy students completed the survey instrument. Students with higher admissions application and interview scores were more likely to be involved in organizations and hold leadership roles, while students with higher admissions grade point averages were less likely to be involved in organizations and leadership roles. Assessing students' involvement in leadership and service roles can assist in the evaluation of students' leadership skills and lead to modification of curricular and co-curricular activities to provide development opportunities. Student involvement in extracurricular activities may encourage future involvement in and commitment to the pharmacy profession.

Back to the future: autobiographical planning and the functionality of mind-wandering.

PubMed

Baird, Benjamin; Smallwood, Jonathan; Schooler, Jonathan W

2011-12-01

Given that as much as half of human thought arises in a stimulus independent fashion, it would seem unlikely that such thoughts would play no functional role in our lives. However, evidence linking the mind-wandering state to performance decrement has led to the notion that mind-wandering primarily represents a form of cognitive failure. Based on previous work showing a prospective bias to mind-wandering, the current study explores the hypothesis that one potential function of spontaneous thought is to plan and anticipate personally relevant future goals, a process referred to as autobiographical planning. The results confirm that the content of mind-wandering is predominantly future-focused, demonstrate that individuals with high working memory capacity are more likely to engage in prospective mind-wandering, and show that prospective mind-wandering frequently involves autobiographical planning. Together this evidence suggests that mind-wandering can enable prospective cognitive operations that are likely to be useful to the individual as they navigate through their daily lives.

Space mechanisms needs for future NASA long duration space missions

NASA Technical Reports Server (NTRS)

Fusaro, Robert L.

1991-01-01

Future NASA long duration missions will require high performance, reliable, long lived mechanical moving systems. In order to develop these systems, high technology components, such as bearings, gears, seals, lubricants, etc., will need to be utilized. There has been concern in the NASA community that the current technology level in these mechanical component/tribology areas may not be adequate to meet the goals of long duration NASA mission such as Space Exploration Initiative (SEI). To resolve this concern, NASA-Lewis sent a questionnaire to government and industry workers (who have been involved in space mechanism research, design, and implementation) to ask their opinion if the current space mechanisms technology (mechanical components/tribology) is adequate to meet future NASA Mission needs and goals. In addition, a working group consisting of members from each NASA Center, DoD, and DOE was established to study the technology status. The results of the survey and conclusions of the working group are summarized.

Art Phelps was one of the ``grand old men'' in field of gaseous electronics. He was a graduate student when the GEC got started and he attended almost all of the meetings over the years. During his remarkably long career, he produced a number of the classic papers in our field as a glance at Web of Science will show. Art was my mentor and friend, and I had the privilege of working with him for many years on various topics related mainly to electron scattering and transport in weakly ionized gases. In this talk, I will discuss the originality of some of his early work on these subjects in the context of their times, focusing in particular on his publications from the mid-1960's with his colleagues from Westinghouse Research Laboratories. These report the first numerical solutions of the Boltzmann equation for electrons, to my knowledge, and they inspired much subsequent work related to the extraction of quantitative information about low-energy electron scatting with simple gases from measurements of macroscopic parameters (mobility, diffusion,..). I will outline some of the work he and I did together in this topical area using more sophisticated numerical techniques. This and other work in the field eventually led to the establishment of the ongoing GEC Plasma Data Exchange Project which now involves a number of people (the LXCat team), as discussed in Tuesday's workshop. The LXCat team had completed work on noble gases and had just started working on evaluations of cross sections for simple molecules when Art died. We are fortunate to have had his involvement on these projects. Art had ideas for future work in these areas, and some are included in a long e-mail message from Art a couple of years ago that I will share because it includes some suggestions [to the community] for future work.

Psychoanalysis and CMHM were once enemies. Psychoanalysis has made noteworthy advances toward the CMHM idea both in technique changes and in community involvement. It is possible that CMHM may finally reject all psychoanalytic contribution and face its future without a theory. If that takes place, the CMHM some day in its future may turn a corner and find itself face to face with the lonely, individual man, conscious of his past and fearful of the unexplained anxiety within him. It is then that the CMHM will find itself once again studying the works of Herbert Marcuse, Erik Erikson, Sigmund Freud, and the psychoanalytic world.

Prevention of work disability due to musculoskeletal disorders: the challenge of implementing evidence.

Loisel, Patrick; Buchbinder, Rachelle; Hazard, Rowland; Keller, Robert; Scheel, Inger; van Tulder, Maurits; Webster, Barbara

2005-12-01

The process of returning disabled workers to work presents numerous challenges. In spite of the growing evidence regarding work disability prevention, little uptake of this evidence has been observed. One reason for limited dissemination of evidence is the complexity of the problem, as it is subject to multiple legal, administrative, social, political, and cultural challenges. A literature review and collection of experts' opinion is presented, on the current evidence for work disability prevention, and barriers to evidence implementation. Recommendations are presented for enhancing implementation of research results. The current evidence regarding work disability prevention shows that some clinical interventions (advice to return to modified work and graded activity programs) and some non-clinical interventions (at a service and policy/community level but not at a practice level) are effective in reducing work absenteeism. Implementation of evidence in work disability is a major challenge because intervention recommendations are often imprecise and not yet practical for immediate use, many barriers exist, and many stakeholders are involved. Future studies should involve all relevant stakeholders and aim at developing new strategies that are effective, efficient, and have a potential for successful implementation. These studies should be based upon a clearer conceptualization of the broader context and inter-relationships that determine return to work outcomes.

Climate negotiators' and scientists' assessments of the climate negotiations

Dannenberg, Astrid; Zitzelsberger, Sonja; Tavoni, Alessandro

2017-06-01

Climate negotiation outcomes are difficult to evaluate objectively because there are no clear reference scenarios. Subjective assessments from those directly involved in the negotiations are particularly important, as this may influence strategy and future negotiation participation. Here we analyse the perceived success of the climate negotiations in a sample of 656 experts involved in international climate policy. Respondents were pessimistic when asked for specific assessments of the current approach centred on voluntary pledges, but were more optimistic when asked for general assessments of the outcomes and usefulness of the climate negotiations. Individuals who were more involved in the negotiation process tended to be more optimistic, especially in terms of general assessments. Our results indicate that two reinforcing effects are at work: a high degree of involvement changes individuals' perceptions and more optimistic individuals are more inclined to remain involved in the negotiations.

Involving young people in health promotion, research and policy-making: practical recommendations.

2018-05-18

Youth is a dynamic and complex transition period in life where many factors jeopardise its present and future health. Youth involvement enables young people to influence processes and decisions that affect them, leading to changes in themselves and their environment (e.g. peers, services, communities and policies); this strategy could be applied to improve health and prevent diseases. Nonetheless, scientific evidence of involving youth in health-related programmes is scarce. The aim of this paper is to describe youth involvement as a health promotion strategy and to compile practical recommendations for health promoters, researchers and policy-makers interested in successful involvement of young people in health-related programmes. These suggestions aim to encourage a positive working synergy between adults and youth during the development, implementation and evaluation of policies, research and/or health promotion efforts that target adolescents.

Ensuring future drinking water supply requires a tough management of groundwater resources. However, recent practices of economic resource control often does not involve aspects of the hydrogeochemical and geohydraulical groundwater system. In respect of analysing the available quantity and quality of future raw water, an effective resource management requires a full understanding of the hydrogeochemical and geohydraulical processes within the aquifer. For example, the knowledge of raw water quality development within the time helps to work out strategies of water treatment as well as planning finance resources. On the other hand, the effectiveness of planed measurements reducing the infiltration of harmful substances such as nitrate can be checked and optimized by using hydrogeochemical modelling. Thus, within the framework of the InnoNet program funded by Federal Ministry of Economics and Technology, a network of research institutes and water suppliers work in close cooperation developing a planning and management tool particularly oriented on water management problems. The tool involves an innovative material flux model that calculates the hydrogeochemical processes under consideration of the dynamics in agricultural land use. The program integrated graphical data evaluation is aligned on the needs of water suppliers.

2002-01-01

NASA Goddard has used its Integrated Mission Design Center (IMDC) to perform more than 150 mission concept studies. The IMDC performs rapid development of high-level, end-to-end mission concepts, typically in just 4 days. The approach to the studies varies, depending on whether the proposed mission is near-future using existing technology, mid-future using new technology being actively developed, or far-future using technology which may not yet be clearly defined. The emphasis and level of detail developed during any particular study depends on which timeframe (near-, mid-, or far-future) is involved and the specific needs of the study client. The most effective mission studies are those where mission capabilities required and emerging technology developments can synergistically work together; thus both enhancing mission capabilities and providing impetus for ongoing technology development.

2015-10-01

Fatigue is an exhaustion state caused by prolonged physical work and mental work, which can reduce working efficiency and even cause industrial accidents. Fatigue is a complex concept involving both physiological and psychological factors. Fatigue can cause a decline of concentration and work performance and induce chronic diseases. Prolonged fatigue may endanger life safety. In most of the scenarios, physical and mental workloads co-lead operator into fatigue state. Thus, it is very important to study the interaction influence and its neural mechanisms between physical and mental fatigues. This paper introduces recent progresses on the interaction effects and discusses some research challenges and future development directions. It is believed that mutual influence between physical fatigue and mental fatigue may occur in the central nervous system. Revealing the basal ganglia function and dopamine release may be important to explore the neural mechanisms between physical fatigue and mental fatigue. Future effort is to optimize fatigue models, to evaluate parameters and to explore the neural mechanisms so as to provide scientific basis and theoretical guidance for complex task designs and fatigue monitoring.

It is important to share information about other countries' pharmacists to optimize cross-border medical cooperation. This paper examines the dispensing systems and the work done by pharmacists in the United Kingdom, Germany, France, Thailand, and Malaysia so as to compare these countries' medical practices and develop a cohesive vision for the future of Japanese pharmacists. All five of the countries have dispensing assistants. Pharmacists in Japan have duties of inventory control, drug dispensing, and providing medication advice. In contrast, assistants working in other countries are responsible for some aspects of dispensing and inventory control, allowing the pharmacists to spend their time and competency in instructing patients on how to take their medication. Because of this, pharmacists were actively involved with health promotion intervention in the United Kingdom, Germany, and France. It is hoped that work done by Japanese pharmacists would transition from primarily dispensing drugs to patient care, advice, and counseling to enrich overall health promotion and health/nutrition counseling.

Educational opportunities for professionals working with children requiring palliative care are central to future development within the specialty across countries. International educational initiatives involving a range of professionals are important for learning with and from others working within the field. To explore the experiences and value to students from participating in an international online discussion forum. This article examines one such initiative; the use of an international asynchronous discussion forum with students in Melbourne, Australia and Belfast, UK who work with children and families. The innovation is examined and student perspectives of the forum's value are presented. Students endorsed the value of the forum, identifying three main areas of learning: differences across locations within countries, respecting different views and being open, and need for continued learning within children's palliative care. The overarching theme 'we are not alone' supported the idea that participation in the international discussion forum enabled students to see a broader perspective. Ideas for future developments of similar forums are also explored.

Perceived functional ability assessed with the spinal function sort: is it valid for European rehabilitation settings in patients with non-specific non-acute low back pain?

The aim of this study involving 170 patients suffering from non-specific low back pain was to test the validity of the spinal function sort (SFS) in a European rehabilitation setting. The SFS, a picture-based questionnaire, assesses perceived functional ability of work tasks involving the spine. All measurements were taken by a blinded research assistant; work status was assessed with questionnaires. Our study demonstrated a high internal consistency shown by a Cronbach’s alpha of 0.98, reasonable evidence for unidimensionality, spearman correlations of >0.6 with work activities, and discriminating power for work status at 3 and 12 months by ROC curve analysis (area under curve = 0.760 (95% CI 0.689–0.822), respectively, 0.801 (95% CI 0.731–0.859). The standardised response mean within the two treatment groups was 0.18 and −0.31. As a result, we conclude that the perceived functional ability for work tasks can be validly assessed with the SFS in a European rehabilitation setting in patients with non-specific low back pain, and is predictive for future work status.

Work motivation is a topic of crucial importance to the success of organizations and societies and the well-being of individuals. We organize the work motivation literature over the last century using a meta-framework that clusters theories, findings, and advances in the field according to their primary focus on (a) motives, traits, and motivation orientations (content); (b) features of the job, work role, and broader environment (context); or (c) the mechanisms and processes involved in choice and striving (process). Our integrative review reveals major achievements in the field, including more precise mapping of the psychological inputs and operations involved in motivation and broadened conceptions of the work environment. Cross-cutting trends over the last century include the primacy of goals, the importance of goal striving processes, and a more nuanced conceptualization of work motivation as a dynamic, goal-directed, resource allocation process that unfolds over the related variables of time, experience, and place. Across the field, advances in methodology and measurement have improved the match between theory and research. Ten promising directions for future research are described and field experiments are suggested as a useful means of bridging the research-practice gap.

Environmental public health disasters involving hazardous contaminants may have devastating effects. While much is known about their immediate devastation, far less is known about long-term impacts of these disasters. Extensive latent and chronic long-term public health effects may occur. Careful evaluation of contaminant exposures and long-term health outcomes within the constraints imposed by limited financial resources is essential. Here, we review epidemiologic methods lessons learned from conducting long-term evaluations of four environmental public health disasters involving hazardous contaminants at Chernobyl, the World Trade Center, Bhopal, and Graniteville (South Carolina, USA). We found several lessons learned which have direct implications for the on-going disaster recovery work following the Fukushima radiation disaster or for future disasters. These lessons should prove useful in understanding and mitigating latent health effects that may result from the nuclear reactor accident in Japan or future environmental public health disasters.

Compassion Fatigue Following the September 11 Terrorist Attacks: A Study of Secondary Trauma among New York City Social Workers

Experience suggests that individuals working in the caring and psychotherapeutic professions are among those to provide mental health services to disaster victims suffering from psychological trauma following catastrophic events. Yet, few studies have focused on the emotional exhaustion from working with such clients, referred to as compassion fatigue (CF) in this study, and how CF differs from other occupational hazards, such as secondary trauma (ST) and job burnout. In the present study, we used recently validated scales to predict ST and job burnout related to providing services to those affected by the World Trade Center (WTC) attacks. Our study data were based on a random survey of 236 social workers living in New York City (NYC), over 80% of which reported being involved in post-WTC disaster counseling efforts. Our analyses indicated that controlling for demographic factors, years of counseling, and personal trauma history, ST was positively associated with WTC recovery involvement (p < .001) and negatively associated with having a supportive work environment (p < .01). In contrast, job burnout was negatively associated with having a supportive work environment (p < .01), but not associated with WTC involvement or WTC counseling efforts. We discuss these results in light of future conceptual and empirical research needs. PMID:15298076

The last decade has witnessed very active development in two broad, but separate fields, both involving understanding and modeling of how individuals move in time and space (hereafter called "travel behavior analysis" or "human mobility analysis"). One field comprises transportation researchers who have been working in the field for decades and the other involves new comers from a wide range of disciplines, but primarily computer scientists and physicists. Researchers in these two fields work with different datasets, apply different methodologies, and answer different but overlapping questions. It is our view that there is much, hidden synergy between the two fields that needs to be brought out. It is thus the purpose of this paper to introduce datasets, concepts, knowledge and methods used in these two fields, and most importantly raise cross-discipline ideas for conversations and collaborations between the two. It is our hope that this paper will stimulate many future cross-cutting studies that involve researchers from both fields.

2006-01-01

This study documents the investigation of qualitative habitability and human factors feedback provided by scientists, engineers, and crewmembers on lessons learned from the ISS Program. A thorough review and understanding of this data is critical in charting NASA's future path in space exploration. NASA has been involved in ensuring that the needs of crewmembers to live and work safely and effectively in space have been met throughout the ISS Program. Human factors and habitability data has been collected from every U.S. crewmember that has resided on the ISS. The knowledge gained from both the developers and inhabitants of the ISS have provided a significant resource of information for NASA and will be used in future space exploration. The recurring issues have been tracked and documented; the top 5 most critical issues have been identified from this data. The top 5 identified problems were: excessive onsrbit stowage; environment; communication; procedures; and inadequate design of systems and equipment. Lessons learned from these issues will be used to aid in future improvements and developments to the space program. Full analysis of the habitability and human factors data has led to the following recommendations. It is critical for human factors to be involved early in the design of space vehicles and hardware. Human factors requirements need to be readdressed and redefined given the knowledge gained during previous ISS and long-duration space flight programs. These requirements must be integrated into vehicle and hardware technical documentation and consistently enforced. Lastly, space vehicles and hardware must be designed with primary focus on the user/operator to successfully complete missions and maintain a safe working environment. Implementation of these lessons learned will significantly improve NASA's likelihood of success in future space endeavors.

This is a descriptive-exploratory study with a quantitative approach, with the objective of identifying how nurses perceive psychological harassment at work, the behaviors experienced and the variables involved. In collecting data, two questionnaires were used: one socio-professional and another for identifying the behaviors involving psychological harassment experienced by the subjects in the previous twelve months, along with the duration and frequency of the behaviors. At the end of the questionnaire, a dichotomous question was added, which addressed nurses' perceptions in relation to feeling victimized by psychological harassment at work. Both the questionnaires were applied in electronic and print format between May and September 2010. The data was analyzed through descriptive statistics. The results showed that some of the subjects felt that they were victims of psychological harassment. Only the variables related to characterization of the psychological harassment presented significant association. The following were highlighted among the most-referred-to behaviors: "They question your decisions" and "You receive verbal attacks criticizing work you have done". It's important to open spaces for discussing violence at work, so that managers may establish strategic measures for preventing and containing this type of violence, so as to ensure health, dignity and well-being at work. It is also important to discuss this issue in the academic space, so as to give the theme greater visibility, such that future nurses will be able to identify and appropriately confront this type of violence.

To describe staff nurse work engagement, identify predictors by generational cohort, present implications for nurse managers and suggest future research. A global nurse shortage looms. While an adequate supply of nurses is needed to ensure access to care, access to quality care may be enhanced by an adequate supply of highly engaged nurses-those who are dedicated, energized, and absorbed. Nurses have long reported the presence of energy depleting practice environments. Nurses practicing in professional practice environments may be more engaged. A non-experimental survey design was executed. Direct care Registered Nurses (n = 747) working in five rural acute care hospitals completed questionnaires to assess work engagement (Utrecht Work Engagement Scale-9), decisional involvement (Decisional Involvement Scale), relational coordination (Relational Coordination Survey) and the nursing practice environment (Practice Environment Scale of the Nursing Work Index). Descriptive, correlational and regression analyses examined work engagement and predictors by generational cohort. With the exception of the absorption component, no statistically significant differences in engagement emerged across generational cohorts. Predictors of engagement differed by cohort, however across all cohorts, professional nursing practice environments predicted nurse work engagement. Professional nursing practice environments are significantly associated with nurse work engagement. Enhancing nurse work engagement is a complex challenge. Generational cohorts may respond to different strategies to enhance engagement. © 2013 John Wiley & Sons Ltd.

Climate negotiators’ and scientists’ assessments of the climate negotiations

2017-01-01

Climate negotiation outcomes are difficult to evaluate objectively because there are no clear reference scenarios. Subjective assessments from those directly involved in the negotiations are particularly important, as this may influence strategy and future negotiation participation. Here we analyze the perceived success of the climate negotiations in a sample of more than 600 experts involved in international climate policy. Respondents were pessimistic when asked for specific assessments of the current approach centered on voluntary pledges, but were more optimistic when asked for general assessments of the outcomes and usefulness of the climate negotiations. Individuals who are more involved in the negotiation process tended to be more optimistic, especially in terms of general assessments. Our results indicate that two reinforcing effects are at work: a high degree of involvement changes individuals’ perceptions and more optimistic individuals are more inclined to remain involved in the negotiations.

2011-10-01

The present study investigates the dental work in terms of time distribution and mechanical exposure in value-adding work (VAW) and non-VAW. Further rationalisation of dental work would typically involve an increase in the proportion of VAW. Information on mechanical exposure within the classes of VAW and non-VAW may be used to predict possible implications of rationalisation. Sixteen dentists were investigated. Using a data logger, postures and movements were continuously recorded for each subject during the 4 h of work, which included the 45 min of video recording. Time distribution and mechanical exposure for the six different work activities identified were evaluated from the video recordings, using a loss analysis technique. VAW, which comprised 54% of the total working time, generally implied significantly more constrained mechanical exposures as compared with non-VAW. The results suggest that future rationalisation of dental work, involving a reduction of non-VAW, may increase the risk of developing musculoskeletal disorders. Statement of Relevance: The present study illustrates the potential effects of rationalisation on biomechanical exposures for dentists. The results highlight the significance of integrating ergonomic issues into the rationalisation process in dentistry in addition to ordinary workstation and tool design improvements performed by ergonomists.

The Evidence Base for Interventions Targeting Individuals With Work-Related PTSD: A Systematic Review and Recommendations.

Torchalla, Iris; Strehlau, Verena

2018-03-01

The purpose of this study was to summarize the evidence base for interventions targeting individuals with work-related posttraumatic stress disorder (PTSD), to make recommendations for clinicians and administrative decision makers involved in their rehabilitation, and to guide future research in this area. Particular attention was given to studies that were conducted in naturalistic clinical settings or in a workers' compensation claim context. Electronic searches of Cochrane Central Register of Controlled Trials, MEDLINE, PubMed, PsycINFO, CINAHL, PILOTS, and EMBASE identified 11 articles. Study populations included railroad personnel, police officers, disaster workers, and individuals with industrial injuries. Interventions included trauma-focused cognitive-behavioral therapy and eye movement desensitization and reprocessing. Several studies specifically targeted workers who had failed to return to work (RTW) after standard PTSD treatment. The results suggest that psychotherapy interventions are beneficial for helping clients recover from PTSD symptoms and RTW. In studies that reported on work status, RTW rates increased over time and generally lay between 58% and 80% across follow-up time points. Narrative impressions were supplemented by calculation of Risk Differences for individuals working at pretreatment versus posttreatment. Clinical consideration, methodological issues limiting the current body of work, and recommendations for future research are discussed.

To understand the similarities and differences in the employment participation of people living with arthritis across the life course. Focus groups and interviews were conducted with young (ages 18-34 years, n = 7), middle-aged (ages 35-54 years, n = 13) and older adults (>55 years, n = 25) with arthritis. Participants were asked about the impact of arthritis on employment, experiences with health-related changes, career progression and social role involvement. A modified grounded theory approach was used to inductively analyze the data. Young adults indicated the school-to-work transition as being influential in their employment and described the need to direct their time and energy toward finding work that accommodated health and met career aspirations. Middle-aged adults described how the transition from good health to an arthritis diagnosis disrupted involvement in diverse social roles. However, they often downplayed the impact of arthritis on employment. Older adults described the work-to-retirement transition and their decline in physical functioning as contributing to changing involvement in the labor market. Transitions related to health, career progression and social role involvement shaped employment experiences, and represent opportunities for future research and practice that is tailored to life course issues. Implications for rehabilitation Little is known about the work experiences of young- and middle-aged adults with arthritis and how they compare to their older counterparts. Life course theory offers an important framework for research and practice by providing a perspective to enhance our understanding of how employment participation differs across phases of life. Salient and diverse changes related to health, career and social role involvement were identified at each life phase and shaped employment. Rehabilitation practitioners should pay special attention to a client's age, life phase and work history as a strategy to enhance the delivery of interventions that promote work participation.

Working memory involved in predicting future outcomes based on past experiences.

Deficits in working memory have been shown to contribute to poor performance on the Iowa Gambling Task [IGT: Bechara, A., & Martin, E.M. (2004). Impaired decision making related to working memory deficits in individuals with substance addictions. Neuropsychology, 18, 152-162]. Similarly, a secondary memory load task has been shown to impair task performance [Hinson, J., Jameson, T. & Whitney, P. (2002). Somatic markers, working memory, and decision making. Cognitive, Affective, & Behavioural Neuroscience, 2, 341-353]. In the present study, we investigate whether the latter findings were due to increased random responding [Franco-Watkins, A. M., Pashler, H., & Rickard, T. C. (2006). Does working memory load lead to greater impulsivity? Commentary on Hinson, Jameson, and Whitney's (2003). Journal of Experimental Psychology: Learning, Memory & Cognition, 32, 443-447]. Participants were tested under Low Working Memory (LWM; n=18) or High Working Memory (HWM; n=17) conditions while performing the Reversed IGT in which punishment was immediate and reward delayed [Bechara, A., Dolan, S., & Hindes, A. (2002). Decision making and addiction (part II): Myopia for the future or hypersensitivity to reward? Neuropsychologia, 40, 1690-1705]. In support of a role for working memory in emotional decision making, compared to the LWM condition, participants in the HWM condition made significantly greater number of disadvantageous selections than that predicted by chance. Performance by the HWM group could not be fully explained by random responding.

2011-02-01

The problem of shortage of physicians has been discussed controversially in Germany for years, and the different positions of the interest groups involved have not been resolved. The question of the present and anticipated future requirement of physicians is central for an appropriate and necessary medical care of the population. In the analysis, supply and demand of medical care have to be distinguished. Relatively reliable data do exist for the supply of physicians; however, the changing number of working hours that male and--in particular female--physicians are willing to contribute should be taken into consideration. Reliable data for the future demand are presently not available. Several variables (e.g., demography, disease spectrum of an aging society, medical progress, the changing rules of working hours, and the shift of medical care between hospital and practice care) depend on future developments. Considering the existing serious indicators of a growing shortage of physicians, it is recommended to put more effort into the scientific investigation of these factors. More profound data should improve the basis for decisions in health and education politics.

Optimism/pessimism and future orientation as predictors of suicidal ideation: Are there ethnic differences?

PubMed

Yu, Elizabeth A; Chang, Edward C

2016-10-01

The present study sought to test the generalizability of Chang et al.'s (2013) model, which suggests that optimism/pessimism and future orientation function as additive and interactive predictors of suicidal risk, to specific ethnic minority college student groups (i.e., Asian Americans, African Americans, and Latino Americans). The present study used Chang et al.'s (2013) model to predict suicidal ideation among 81 (34 male and 47 female) Asian-American, 71 (22 male and 49 female) African-American adults, and 83 (34 male and 49 female) Latino-American college students. Our results indicated that this model did not predict suicidal ideation well for Asian-American college students; however, it did work well to predict suicidal ideation for African-American and Latino-American college students. Our findings indicate that optimism/pessimism and future orientation are important positive cognitions involved with suicidal ideation for African-American and Latino-American college students. Further research is needed to better understand the cultural underpinnings of how these positive cognitions work to predict suicide-related outcomes.

2018-03-01

To explore in-depth understanding of providers' experiences when involved in a return-to-work (RTW) intervention offered during cancer treatment. Semi-structured individual interviews and participant observations at a hospital department and two municipal job centers were carried out, including ten providers (physicians, nurses and social workers). A phenomenological-hermeneutic approach was applied, involving coding, identification of themes and interpretation of findings. Three major themes were identified: Treatment first, Work as an integrated component in cancer rehabilitation, and Challenges in bringing up work issues. Differences in providers' experiences of the RTW intervention offered to cancer patients were found: in the hospital setting RTW was a second priority, whereas in the municipality job centers it was an integrated component. Further studies are needed to investigate how and when occupational rehabilitation services can be implemented across sectors to support cancer patients' RTW. In the future, work issues ought to be systematically presented by providers across sectors as early as possible to support cancer patients' RTW. Cancer patients' individual needs and thoughts about RTW are to be identified by both health care providers during treatment and social workers at the municipality level and shared across sectors. © 2017 John Wiley & Sons Ltd.

The ANNETTE Project (Advanced Networking for Nuclear Education and Training and Transfer of Expertise) is well underway, and one of its work packages addresses the design, development and implementation of nuclear fusion training. A systematic approach is used that leads to the development of new training courses, based on identified nuclear competences needs of the work force of (future) fusion reactors and on the current availability of suitable training courses. From interaction with stakeholders involved in the ITER design and construction or the JET D-T campaign, it became clear that the lack of nuclear safety culture awareness already has an impact on current projects. Through the collaboration between the European education networks in fission (ENEN) and fusion (FuseNet) in the ANNETTE project, this project is well positioned to support the development of nuclear competences for ongoing and future fusion projects. Thereby it will make a clear contribution to the realization of fusion energy.

Involving patients and the public in the NHS.

Clough, Christopher

2003-01-01

Involving patients and the public in the NHS is a new strategic initiative by the Deparment of Health. Over time it will make a significant change to how services are designed and delivered. Doctors need to be aware of this new legislation and the change in the patient/clinician dynamic it embraces. In the clinical setting a change of culture is required so that doctors move to working in partnerships with their patients. Within trusts, hospital or otherwise, structures must be in place to ensure appropriate patient/public involvement. Health service workers and the public will need to understand the skills required from both sides for a constructive partnership to emerge. It is hoped that the prioritising of health service resources in the future will be the result of a more democratic process involving patients, public and health service workers.

Future time perspective (FTP) may predict individual attitudes and behaviors. However, FTP research includes different FTP conceptualizations and outcomes which hinder generalizing its findings. To solve the inconsistencies in FTP research and generalize the magnitude of FTP as a driver of motivation and behavior, we conducted the first systematical synthesis of FTP relationships in three crucial life domains. Our meta-analyses of FTP studies in education (k = 28), work (k = 17), and health (k = 32) involved N = 31,558 participants, and used a conceptual model for grouping FTP constructs. To address different outcome types, we applied the Theory of Planned Behavior when coding the studies. FTP relationships with outcomes were small-to-medium, were generalizable across domains, and were strongest when the FTP construct included a mixture of cognition, behavioral intention, and affect and, in education, when the FTP measure was domain specific rather than general. There were cross-cultural differences in FTP-outcome relationships. The strength of the FTP-outcome types relationship varied for attitudes, perceived behavioral control, behavioral intention, and behaviors. The lowest effect sizes were found for FTP predicting actual behaviors in education, work, and health and between FTP and health attitudes. Theoretical implications of the findings and future research directions are discussed.

The surveys for sensitivities to fibers and potential impacts from fiber induced failures begins with a review of the survey work completed to date and then describes an impact study involving four industrial installations located in Virginia. The observations and results from both the surveys and the study provide guidelines for future efforts. The survey work was done with three broad objectives: (1) identify the pieces of potentially vulnerable equipment as candidates for test; (2) support the transfer function work by gaining an understanding of how fibers could get into a building; and (3) support the economic analysis by understanding what would happen if fibers precipitated a failure in an item of equipment.

The ability to remember past events and imagine future events (episodic future thinking-EFT) has been shown to decline with aging. However, only few studies have analyzed the cognitive mechanisms involved in EFT in both young and older adults. The present study examined the role of working memory and inhibition on age-related differences between young and older adults in EFT, in response to short sentences reflecting common events, some of which were repeated in both conditions (past and future). Thirty-seven young and 36 older adults completed an adapted version of the autobiographical interview, in which sentences were presented. Results showed that processing resources explained a significant part of the variance in the amount of details; in particular, inhibition explained the amount of external details produced in the future condition. In addition, using sentences, the older group did not differ from the young adults in terms of the proportion of internal details recalled in the past condition, whereas they produced a lower proportion of internal details in the future condition. The effect of using structured material was reinforced by repeating some sentences in the past. Further, only older adults rated the remembered episodes as more emotionally salient and relevant than the imagined ones. Age-related differences between young and older adults in EFT appear to depend on the type of material used, on basic mechanisms of cognition, and are characterized by both quantitative and qualitative differences.

Climate change and resource scarcity pose significant threats to healthcare delivery. Nurses should develop the skills to cope with these challenges in the future. Skills sessions using sustainability scenarios can help nursing students to understand the effect climate change and resource scarcity will have on health care. Involving design students in clinical skills sessions can encourage multidisciplinary working and help to find solutions to promote healthcare sustainability.

Right-ear precedence and vocal emotion contagion: The role of the left hemisphere.

Schepman, Astrid; Rodway, Paul; Cornmell, Louise; Smith, Bethany; de Sa, Sabrina Lauren; Borwick, Ciara; Belfon-Thompson, Elisha

2018-05-01

Much evidence suggests that the processing of emotions is lateralized to the right hemisphere of the brain. However, under some circumstances the left hemisphere might play a role, particularly for positive emotions and emotional experiences. We explored whether emotion contagion was right-lateralized, lateralized valence-specifically, or potentially left-lateralized. In two experiments, right-handed female listeners rated to what extent emotionally intoned pseudo-sentences evoked target emotions in them. These sound stimuli had a 7 ms ear lead in the left or right channel, leading to stronger stimulation of the contralateral hemisphere. In both experiments, the results revealed that right ear lead stimuli received subtly but significantly higher evocation scores, suggesting a left hemisphere dominance for emotion contagion. A control experiment using an emotion identification task showed no effect of ear lead. The findings are discussed in relation to prior findings that have linked the processing of emotional prosody to left-hemisphere brain regions that regulate emotions, control orofacial musculature, are involved in affective empathy processing areas, or have an affinity for processing emotions socially. Future work is needed to eliminate alternative interpretations and understand the mechanisms involved. Our novel binaural asynchrony method may be useful in future work in auditory laterality.

1. The scope of professional nursing practice obligates the individual nurse to make participation in public policy formulation part of their professional work. Helping to shape the health and welfare of our communities and the nation fulfills part of nursing's contract with America's citizens. 2. Nurses have valuable, special knowledge and skills which "fit" very well with political involvement and policy making activities. 3. Occupational and environmental health nurses have a special responsibility to influence public policies that affect America's work force by using the five Cs of political action to enable effective involvement. 4. Nursing's professional associations act as advocates for nursing's unique interests and causes. Nurses who join and become active in associations such as AAOHN and ANA are instrumental in protecting the profession of nursing and ensuring that health care issues are at the top of the political agenda at all government levels.

To clarify the occupational health (OH) issues that arose, what actions were taken, and the OH performances during the disaster involving the Fukushima Daiichi Nuclear Power Plant and thus improve the OH management system with respect to long-term decommissioning work and preparation for future disasters. We used information in advisory reports to the Tokyo Electric Power Company by an OH expert group, observation through support activities, and data officially released by the Tokyo Electric Power Company. Occupational health issues transitioned as work progressed and seasons changed. They were categorized into OH management system establishment, radiation exposure control, heat illness prevention, infectious disease prevention and control, and fitness for workers' duties. Occupational health management systems involving OH experts should be implemented to manage multiple health risks with several conflicts and trade-offs after a disaster.

Objectives Involving general practitioners (GPs) in the commissioning/purchasing of services has been an important element in English health policy for many years. The Health and Social Care Act 2012 handed responsibility for commissioning of the majority of care for local populations to GP-led Clinical Commissioning Groups (CCGs). In this paper, we explore GP attitudes to involvement in commissioning and future intentions for engagement. Design and setting Survey of a random sample of GPs across England in 2015. Method The Eighth National GP Worklife Survey was distributed to GPs in spring 2015. Responses were received from 2611 respondents (response rate = 46%). We compared responses across different GP characteristics and conducted two sample tests of proportions to identify statistically significant differences in responses across groups. We also used multivariate logistic regression to identify the characteristics associated with wanting a formal CCG role in the future. Results While GPs generally agree that they can add value to aspects of commissioning, only a minority feel that this is an important part of their role. Many current leaders intend to quit in the next 5 years, and there is limited appetite among those not currently in a formal role to take up such a role in the future. CCGs were set up as ‘membership organisations’ but only a minority of respondents reported feeling that they had ‘ownership’ of their local CCG and these were often GPs with formal CCG roles. However, respondents generally agree that the CCG has a legitimate role in influencing the work that they do. Conclusion CCGs need to engage in active succession planning to find the next generation of GP leaders. GPs believe that CCGs have a legitimate role in influencing their work, suggesting that there may be scope for CCGs to involve GPs more fully in roles short of formal leadership. PMID:28596217

Automated Work Package: Conceptual Design and Data Architecture

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

Al Rashdan, Ahmad; Oxstrand, Johanna; Agarwal, Vivek

The automated work package (AWP) is one of the U.S. Department of Energy’s (DOE) Light Water Reactor Sustainability Program efforts to enhance the safety and economics of the nuclear power industry. An AWP is an adaptive and interactive work package that intelligently drives the work process according to the plant condition, resources status, and users progress. The AWP aims to automate several manual tasks of the work process to enhance human performance and reduce human errors. Electronic work packages (eWPs), studied by the Electric Power Research Institute (EPRI), are work packages that rely to various extent on electronic data processingmore » and presentation. AWPs are the future of eWPs. They are envisioned to incorporate the advanced technologies of the future, and thus address the unresolved deficiencies associated with the eWPs in a nuclear power plant. In order to define the AWP, it is necessary to develop an ideal envisioned scenario of the future work process without any current technology restriction. The approach followed to develop this scenario is specific to every stage of the work process execution. The scenario development resulted in fifty advanced functionalities that can be part of the AWP. To rank the importance of these functionalities, a survey was conducted involving several U.S. nuclear utilities. The survey aimed at determining the current need of the nuclear industry with respect to the current work process, i.e. what the industry is satisfied with, and where the industry envisions potential for improvement. The survey evaluated the most promising functionalities resulting from the scenario development. The results demonstrated a significant desire to adopt the majority of these functionalities. The results of the survey are expected to drive the Idaho National Laboratory (INL) AWP research and development (R&D). In order to facilitate this mission, a prototype AWP is needed. Since the vast majority of earlier efforts focused on the frontend aspects of the AWP, the backend data architecture was researched and developed in this effort. The backend design involved data architecture aspects. It was realized through this effort that the key aspects of this design are hierarchy, data configuration and live information, data templates and instances, the flow of work package execution, the introduction of properties, and the means to interface the backend to the frontend. After the backend design was developed, a data structure was built to reflect the developed data architecture. The data structure was developed to accommodate the fifty functionalities identified by the envisioned scenario development. The data structure was evaluated by incorporating an example work order from the nuclear power industry. The implementation resulted in several optimization iterations of the data structure. In addition, the rearrangement of the work order information to fit the data structure highlighted several possibilities for improvement in the current work order design, and significantly reduced the size of the work order.« less

The first nationwide, population-based study of Swedish pediatric oncologists was conducted in 2006 and it revealed that various aspects of their life satisfaction obviously influenced their stress-resilience. This second part of the study, with a response rate of 89% in the target group, therefore, focused on their life satisfaction and the role of personality, work-related aspects, and emotional distress related to type of medical center and gender. This descriptive study was based on a cross-sectional mail survey with questionnaires involving 90 pediatric oncologists. Using hierarchical regression models, their total, present, past, and future life satisfaction was analyzed. The vast majority (76.7%) stated that working in this medical field was very stimulating for their personal development. Male pediatricians were more satisfied with their present lives and physicians working at academic medical centers were more confident about the future. Some oncologists (13.4%), in particular females at non-academic medical centers, needed professional help dealing with work-related psychological problems. Personality trait (Hedonic Capacity) and low levels of depression contributed to every aspect of overall life satisfaction. Work-related aspects influenced present and future life satisfaction. The models explained between 5% and 43% of the variance in life satisfaction in the whole group. Pediatric oncologists face life-threatening conditions and psychosocial issues factors that may negatively influence their life satisfaction. This study group, a single population of physicians, is characterized by an optimistic attitude and stable emotional status pointing to a high level of satisfaction, which is probably a main basic condition when meeting seriously ill children.

The advent of canine performance science: offering a sustainable future for working dogs.

2015-01-01

Working and sporting dogs provide an essential contribution to many industries worldwide. The common development, maintenance and disposal of working and sporting dogs can be considered in the same way as other animal production systems. The process of 'production' involves genetic selection, puppy rearing, recruitment and assessment, training, housing and handling, handler education, health and working life end-point management. At present, inefficiencies throughout the production process result in a high failure rate of dogs attaining operational status. This level of wastage would be condemned in other animal production industries for economic reasons and has significant implications for dog welfare, as well as public perceptions of dog-based industries. Standards of acceptable animal use are changing and some historically common uses of animals are no longer publicly acceptable, especially where harm is caused for purposes deemed trivial, or where alternatives exist. Public scrutiny of animal use appears likely to increase and extend to all roles of animals, including working and sporting dogs. Production system processes therefore need to be transparent, traceable and ethically acceptable for animal use to be sustainable into the future. Evidence-based approaches already inform best practice in fields as diverse as agriculture and human athletic performance. This article introduces the nascent discipline of canine performance science, which aims to facilitate optimal product quality and production efficiency, while also assuring evidence-based increments in dog welfare through a process of research and development. Our thesis is that the model of canine performance science offers an objective, transparent and traceable opportunity for industry development in line with community expectations and underpins a sustainable future for working dogs.

Background: Environmental public health disasters involving hazardous contaminants may have devastating effects. While much is known about their immediate devastation, far less is known about long-term impacts of these disasters. Extensive latent and chronic long-term public health effects may occur. Careful evaluation of contaminant exposures and long-term health outcomes within the constraints imposed by limited financial resources is essential. Methods: Here, we review epidemiologic methods lessons learned from conducting long-term evaluations of four environmental public health disasters involving hazardous contaminants at Chernobyl, the World Trade Center, Bhopal, and Graniteville (South Carolina, USA). Findings: We found several lessons learned which have direct implications for the on-going disaster recovery work following the Fukushima radiation disaster or for future disasters. Interpretation: These lessons should prove useful in understanding and mitigating latent health effects that may result from the nuclear reactor accident in Japan or future environmental public health disasters.

The purpose of the study is to identify domains of influence on co-workers' ability to be supportive of returning worker during the work reintegration (WR) process. An ethnographic study design was chosen involving fieldwork at four different workplaces, at an emergency care service, a waste disposal company and at two nursing homes. Qualitative methods for inquiry were used including participant observation, individual- and group interviews of 30 participants. Data were coded and analysed according to a grounded theory approach. Four themes were identified related to domains of influence on co-workers' ability to be supportive of returning worker during the WR process: (1) organisation of work and level of interaction; (2) disruption of work routines, (3) relationship with returning worker and (4) attitudes towards sick leave. The WR process after long-term sick leave is not only influenced by the WR's arrangements made, but also by the co-workers' responses to the process. Work arrangements not only affect the returning worker's ability to return-to-work (RTW) successfully, but also the co-workers' ability to be supportive and their ability to take active part in the process. Implications for Rehabilitation The process of WR after long-term sick leave involves interaction with co-workers. Domains of influence is in the co-workers' perspective influencing their ability to be supportive during reintegration of a returning worker. Future WR management could benefit from integrating the conditions for co-worker support. We encourage co-workers to be involved in the RTW planning, monitoring and evaluation with particular focus on how the WR arrangements are influencing their work and their ability to be supportive.

The activity of Phase I of the Waste Management Working Group under the United States - Japan Joint Nuclear Energy Action Plan started in 2007. The US-Japan JNEAP is a bilateral collaborative framework to support the global implementation of safe, secure, and sustainable, nuclear fuel cycles (referred to in this document as fuel cycles). The Waste Management Working Group was established by strong interest of both parties, which arise from the recognition that development and optimization of waste management and disposal system(s) are central issues of the present and future nuclear fuel cycles. This report summarizes the activity of themore » Waste Management Working Group that focused on consolidation of the existing technical basis between the U.S. and Japan and the joint development of a plan for future collaborative activities. Firstly, the political/regulatory frameworks related to nuclear fuel cycles in both countries were reviewed. The various advanced fuel cycle scenarios that have been considered in both countries were then surveyed and summarized. The working group established the working reference scenario for the future cooperative activity that corresponds to a fuel cycle scenario being considered both in Japan and the U.S. This working scenario involves transitioning from a once-through fuel cycle utilizing light water reactors to a one-pass uranium-plutonium fuel recycle in light water reactors to a combination of light water reactors and fast reactors with plutonium, uranium, and minor actinide recycle, ultimately concluding with multiple recycle passes primarily using fast reactors. Considering the scenario, current and future expected waste streams, treatment and inventory were discussed, and the relevant information was summarized. Second, the waste management/disposal system optimization was discussed. Repository system concepts were reviewed, repository design concepts for the various classifications of nuclear waste were summarized, and the factors to consider in repository design and optimization were then discussed. Japan is considering various alternatives and options for the geologic disposal facility and the framework for future analysis of repository concepts was discussed. Regarding the advanced waste and storage form development, waste form technologies developed in both countries were surveyed and compared. Potential collaboration areas and activities were next identified. Disposal system optimization processes and techniques were reviewed, and factors to consider in future repository design optimization activities were also discussed. Then the potential collaboration areas and activities related to the optimization problem were extracted.« less

Mutual Contextualization in Tripartite Graphs of Folksonomies

NASA Astrophysics Data System (ADS)

Yeung, Ching-Man Au; Gibbins, Nicholas; Shadbolt, Nigel

The use of tags to describe Web resources in a collaborative manner has experienced rising popularity among Web users in recent years. The product of such activity is given the name folksonomy, which can be considered as a scheme of organizing information in the users' own way. This research work attempts to analyze tripartite graphs - graphs involving users, tags and resources - of folksonomies and discuss how these elements acquire their semantics through their associations with other elements, a process we call mutual contextualization. By studying such process, we try to identify solutions to problems such as tag disambiguation, retrieving documents of similar topics and discovering communities of users. This paper describes the basis of the research work, mentions work done so far and outlines future plans.

Designing the multiple robot work cells is very knowledge-intensive, intricate, and time-consuming process. This paper elaborates the development process of a computer-aided design program for generating the multiple robot work cells which offer a user-friendly interface. The primary purpose of this work is to provide a fast and easy platform for less cost and human involvement with minimum trial and errors adjustments. The automated platform is constructed based on the variant-shaped configuration concept with its mathematical model. A robot work cell layout, system components, and construction procedure of the automated platform are discussed in this paper where integration of these items will be able to automatically provide the optimum robot work cell design according to the information set by the user. This system is implemented on top of CATIA V5 software and utilises its Part Design, Assembly Design, and Macro tool. The current outcomes of this work provide a basis for future investigation in developing a flexible configuration system for the multiple robot work cells.

Workaholism: A Review

PubMed Central

Sussman, Steven

2013-01-01

In this review, I examine the definition, etiology, measurement, prevention and treatment of workaholism, based on a systematic search of the literature. While there is some debate regarding the parameters of the concept, viewed as a negative consequential addiction, workaholism involves excessive time spent working, preoccupation with work to the exclusion of other life domains, loss of control over the parameters of one’s work and disenchantment with work, and negative social, emotional, and health consequences. The etiology of workaholism is not clear but may pertain to persons with compulsive personality traits, who are driven to work harder than that demanded from work contexts, and who have learned to place work as a main means of gratification compared to other lifestyle alternatives. Most measurement approaches rely on self-report questionnaires, tested primarily with convenience samples. Refinement of current assessments is ongoing. Prevention and treatment implications are discussed, which include intra- and extra-personal level approaches. Finally, limitations of the work completed in this arena are mentioned and needed future research directions are suggested. PMID:24273685

Maximizing resilience through diverse levels of inquiry: Prevailing paradigms, possibilities, and priorities for the future

PubMed Central

Luthar, Suniya S.; Brown, Pamela J.

2007-01-01

The study of resilience has two core characteristics: it is fundamentally applied in nature, seeking to use scientific knowledge to maximize well-being among those at risk, and it draws on expertise from diverse scientific disciplines. Recent advances in biological processes have confirmed the profound deleterious effects of harsh caregiving environments, thereby underscoring the importance of early interventions. What remains to be established at this time is the degree to which insights on particular biological processes (e.g., involving specific brain regions, genes, or hormones) will be applied in the near future to achieve substantial reductions in mental health disparities. Aside from biology, resilience developmental researchers would do well to draw upon relevant evidence from other behavioral sciences as well, notably anthropology as well as family, counseling, and social psychology. Scientists working with adults and with children must remain vigilant to the advances and missteps in each others' work, always ensuring caution in conveying messages about the “innateness” of resilience or its prevalence across different subgroups. Our future research agenda must prioritize reducing abuse and neglect in close relationships; deriving the “critical ingredients” in effective interventions and going to scale with these; working collaboratively to refine theory on the construct; and responsibly, proactively disseminating what we have learned about the nature, limits, and antecedents of resilient adaptation across diverse at-risk groups.

Citizen seismology encourages the public involvement to data collection, analysis, and reporting, and has the potential to greatly improve the emergency response to seismic hazard. This of course, is important for scientific achievement due to the dense network. We believed the value of citizen seismology and started with distributing Quake-Catcher-Network (QCN) sensor at schools in Taiwan. While working with teachers, we hoped to motivate the learning of how to read seismograms, what to see in the data, and what to teach in the class. Through lots of workshops and activities, even with near-real time earthquake game competition and board game (quake-nopoly) developed along the way, we came to realize the huge gap between what people need and what we do. And to bridge the gap, a new generation of citizen seismic network is needed. Imagine at work, you receive the alarm from sensors at home that tells you the location, size, and type of anomalous shaking events in the neighborhood. Can this future "warning" system happen, allowing citizen to do emergence response? This is a story about facing the challenge, transforming the doubt of "why do I care" to a future IoT world.

2017-11-01

Construction industry players are known for their low acceptance on the changes. Hence, it is identified that the biggest challenge in the industry is changing the mindset. This paper highlights the importance of transformation in shaping for better future of the industry. Transformation favors innovation and progressive development in the industry and specifically in managing a project. Thus changes in mindset of players with an eye to the future and focus on what is coming are paramount in inculcating the transformation culture in construction eco-system. The key to the success of transformation is the collaborative and cooperative partnering which ensuring the performance of every stage of project delivery. The collaborative, cooperative and concerted effort of all parties involved in the project creates mutual understanding on mission and vision of project. Adopting healthy and harmonious project culture, implementing innovative procurement that emphasis on fair risk sharing should be a working culture. This cooperative partnership should be the future of the project undertaking in the construction industry.

Temperature and number density measurements using Raman scattering in turbulent-supersonic-combusting flows

NASA Astrophysics Data System (ADS)

Jeyashekar, Nigil Satish

Scramjet engines propelled at hypersonic velocities have the potential to replace existing rocket launchers. Commercializing the vehicle is an arduous task, owing to issues relating to low combustion efficiency. The performance, thrust, and speed of the engine can be improved by optimizing: turbulence-chemistry interaction to provide mixing conditions favorable for the chemistry, pressure buildup, and re-circulation of hydrogen throughout the engine. The performance of the engine can be measured, flow and chemical dynamics can be evaluated when all three variables in the transport equations are known. The variables are instantaneous flow velocity, static temperature (refers to the macroscopic temperature and not the molecular species temperature), and total number density at a point in the flow. The motive is to build a non-intrusive tool to measure thermodynamic quantities (static temperature and total number density). This can be integrated with a velocity measurement tool, in the future, to obtain all three variables simultaneously and instantaneously. The dissertation describes in detail the motivation for the proposed work, with introduction to the formalism involved, with a concise literature review, followed by mathematical perspective to obtain the working equations for temperature and number density. The design of the adiabatic burner and the experimental setup used for calibration is discussed with the uncertainty involved in measurements. The measurements are made for a certain set of flow conditions in the laminar burner by Raman scattering and is validated by comparing it to the theoretical/adiabatic flame temperature and mole fraction plots, in lean and rich regime. This technique is applied to turbulent, supersonic, hydrogen-air flame of an afterburning rocket nozzle. The statistics of temperature and total number density versus the corresponding values at adiabatic conditions gives the departure from thermal and chemical equilibrium. The extent of mixing and combustion can be concluded from such statistics. The future work will involve experimental modifications to make line and planar measurements in combusting jets.

Abdurrahman, Muslim

2017-05-01

Enhanced oil recovery (EOR) is a proven method for increasing oil production in many oil fields in the world. Huge oil remaining in the reservoir after primary and secondary recovery stage are the main reason for developing EOR methods. Approximately of 49.50 billion barrels oil as a candidate for EOR activities in Indonesia. This present study focuses on the chemical EOR activities involved surfactant and polymer. This research based on pertinent information from various resources such as journal papers, conference papers, and report from the government. Based on this information, this paper explain in detail the progress of each project and it shows the potential oil field employ chemical EOR in the near future. Generally, the EOR activities can be categorized into two phases such as preliminary study phase and field implementation phase. In the preliminary study, the activities simply involve experimental and/or simulation works. Following the preliminary is the field implementation phase which can be categorized into three phases such as field trial, pilot project, and full-scale. In fact, several activities have been conducted by Lemigas (government oil and gas research center), Institut Teknologi Bandung, Institut Pertanian Bogor. These activities focused on laboratory and simulation work. Those institutions have been developing the chemical formula collaborating with oil companies for applying the EOR method in their oil fields. Currently, status of chemical EOR activities include 5 oil fields under pilot project and 12 oil fields under field trial. There are 7 oil fields applying surfactant, 4 oil fields by alkaline-surfactant-polymer (ASP), 2 oil fields by polymer, 1 oil field by surfactant polymer (SP), and 1 oil field by caustic. According to this information, we will have insight knowledge about the EOR current activities, the main issues, future activities on chemical EOR in Indonesia. Moreover, this study can became the preliminary information for researchers who interested conducting further research and development on the chemical EOR activities in the near future.

Growing food crops to meet global demand and the search for more sustainable cropping systems are increasing the need for new cultivars in key production areas. This study presents the identification of rice traits putatively producing the largest yield benefits in five areas that markedly differ in terms of environmental conditions in the Philippines, India, China, Japan and Italy. The ecophysiological model WARM and sensitivity analysis techniques were used to evaluate phenotypic traits involved with light interception, photosynthetic efficiency, tolerance to abiotic stressors, resistance to fungal pathogens and grain quality. The analysis involved only model parameters that have a close relationship with phenotypic traits breeders are working on, to increase the in vivo feasibility of selected ideotypes. Current climate and future projections were considered, in the light of the resources required by breeding programs and of the role of weather variables in the identification of promising traits. Results suggest that breeding for traits involved with disease resistance, and tolerance to cold- and heat-induced spikelet sterility could provide benefits similar to those obtained from the improvement of traits involved with canopy structure and photosynthetic efficiency. In contrast, potential benefits deriving from improved grain quality traits are restricted by weather variability and markedly affected by G × E interactions. For this reason, district-specific ideotypes were identified using a new index accounting for both their productivity and feasibility. © 2017 John Wiley & Sons Ltd.

Achievable Human Exploration of Mars: Highlights from The Fourth Community Workshop (AM IV)

NASA Technical Reports Server (NTRS)

Thronson, Harley; Cassady, Joseph

2017-01-01

About a half decade ago, several professionals working mainly in industry on scenarios for initial human exploration of Mars together recognized that, under generally similar assumptions, there was a fair degree of similarity among these scenarios. Moreover, opportunities should be sought for greater community input into NASA's own scenario-building for the future of human space flight. A series of focused community workshops were considered to be effective to assess these scenarios and involve more directly the science community, including planetary protection, with industry. Four workshops to date each involve about sixty professional scientists, engineers, technologists, and strategists from NASA, academia, aerospace corporations, the National Academies, consulting organizations, and potential international partners.

2006-01-01

Homeland security involves many applications of fluid mechanics and offers many opportunities for research and development. This review explores a wide selection of fluids topics in counterterrorism and suggests future directions. Broad topics range from preparedness and deterrence of impending terrorist attacks to detection, response, and recovery. Specific topics include aircraft hardening, blast mitigation, sensors and sampling, explosive detection, microfluidics and labs-on-a-chip, chemical plume dispersal in urban settings, and building ventilation. Also discussed are vapor plumes and standoff detection, nonlethal weapons, airborne disease spread, personal protective equipment, and decontamination. Involvement in these applications requires fluid dynamicists to think across the traditional boundaries of the field and to work with related disciplines, especially chemistry, biology, aerosol science, and atmospheric science.

Durand, M J; Vézina, N; Loisel, P; Baril, R; Richard, M C; Diallo, B

2007-03-01

Despite the convergence of scientific data to the effect that interventions in the workplace promote a healthy return to work, the interventions carried out in the real work environment appear to be very heterogeneous and ill-defined. The goal of this review is to identify the different objectives pursued through the workplace interventions carried out in the context of a rehabilitation program, and to describe the activities involved. A descriptive review of the literature, including various research designs, was carried out. This review reveals great heterogeneity in the content of interventions offered in the workplace to workers with musculoskeletal disabilities. The objectives of workplace interventions may range from gathering information in order to reproduce work demands in a clinical setting, to gradually exposing workers to the demands of the real work environment, or permanently reducing the demands of the work situation. A descriptive analysis of the literature also brings to light the diversity of actions carried out, human resources used, and workplace environments involved, while highlighting the few documented process outcome evaluations that have been done of workplace interventions. It is recommended that in future research in this area, efforts be made to better describe the components of the interventions, to develop process outcomes representing the multidimensional results obtained in the workplace, and to differentiate between temporary and permanent modifications made to the work situation.

Dopamine cell firing can encode errors in reward prediction, providing a learning signal to guide future behavior. Yet dopamine is also a key modulator of motivation, invigorating current behavior. Existing theories propose that fast (“phasic”) dopamine fluctuations support learning, while much slower (“tonic”) dopamine changes are involved in motivation. We examined dopamine release in the nucleus accumbens across multiple time scales, using complementary microdialysis and voltammetric methods during adaptive decision-making. We first show that minute-by-minute dopamine levels covary with reward rate and motivational vigor. We then show that second-by-second dopamine release encodes an estimate of temporally-discounted future reward (a value function). We demonstrate that changing dopamine immediately alters willingness to work, and reinforces preceding action choices by encoding temporal-difference reward prediction errors. Our results indicate that dopamine conveys a single, rapidly-evolving decision variable, the available reward for investment of effort, that is employed for both learning and motivational functions.

Ethical Considerations and Planetary Protection for Future Space Exploration - Starting with the Basics

NASA Astrophysics Data System (ADS)

Race, Margaret

2012-07-01

As COSPAR scientists deliberate what types of frameworks and policy approaches may be applicable to future activities by various sectors in space exploration, it also needs to consider the challenging question of what ethical values and foundations should be used in dealing with life, objects and activities in outer space. A 2010 COSPAR Workshop Report on Ethical Considerations for Planetary Protection in Space Exploration recommended that it is appropriate to maintain the existing PP policy aimed at scientific concerns even as we begin to explore various practical approaches to future contamination avoidance policies. It is also appropriate to examine in parallel the ethical considerations applicable to potential indigenous extraterrestrial life, non-living extraterrestrial features and environments, and planned uses and activities involving diverse life from Earth. Since numerous sectors have begun to propose activities raising varied ethical concerns (e.g., protection and management on the moon, strip mining, space synthetic biology, space code of conduct, and commercial space transport), it is timely to initiate serious international discussions about the appropriate ethical foundations and questions applicable to future space exploration. Plans are underway for convening interdisciplinary work groups to explore and deliberate on the values (e.g., intrinsic and instrumental) and ethical foundations that are appropriate for use in deliberations involving potential indigenous extraterrestrial life and the different classes of target objects and environments in our solar system. More than ever, information on bioethics, environmental ethics and geoethics will provide helpful guidance and foundational approaches of relevance to future policy deliberations that seek to go beyond science protection per se.

Working memory and attentional bias on reinforcing efficacy of food.

PubMed

Carr, Katelyn A; Epstein, Leonard H

2017-09-01

Reinforcing efficacy of food, or the relationship between food prices and purchasing, is related to obesity status and energy intake in adults. Determining how to allocate resources for food is a decision making process influenced by executive functions. Attention to appetitive cues, as well as working memory capacity, or the ability to flexibly control attention while mentally retaining information, may be important executive functions involved in food purchasing decisions. In two studies, we examined how attention bias to food and working memory capacity are related to reinforcing efficacy of both high energy-dense and low energy-dense foods. The first study examined 48 women of varying body mass index (BMI) and found that the relationship between attentional processes and reinforcing efficacy was moderated by working memory capacity. Those who avoid food cues and had high working memory capacity had the lowest reinforcing efficacy, as compared to those with low working memory capacity. Study 2 systematically replicated the methods of study 1 with assessment of maintained attention in a sample of 48 overweight/obese adults. Results showed the relationship between maintained attention to food cues and reinforcing efficacy was moderated by working memory capacity. Those with a maintained attention to food and high working memory capacity had higher reinforcing efficacy than low working memory capacity individuals. These studies suggest working memory capacity moderated the relationship between different aspects of attention and food reinforcement. Understanding how decision making process are involved in reinforcing efficacy may help to identify future intervention targets. Copyright © 2017 Elsevier Ltd. All rights reserved.

Micronutrient bioavailability: Dietary Reference Intakes and a future perspective1234

PubMed Central

2010-01-01

This article provides a review of how the challenge of bioavailability was approached in establishing the Dietary Reference Intakes, with a special focus on folic acid, vitamin B-12, β-carotene, iron, selenium, and zinc, the targeted micronutrients for this workshop. In a future perspective, the necessity of having a clear working definition of bioavailability is emphasized. The bioavailability of micronutrients should be considered, with advantage, under subheadings determined by the broad factors that affect bioavailability. Special emphasis is given to giving greater and specific attention to factors involved in the maintenance of homeostasis. These factors, it is argued, are best considered separately from even a broad definition of bioavailability and have the potential to provide new insights into some micronutrient requirements.

The U.S. aeronautical industry was surveyed to determine if current and future transonic testing requirements are sufficient to justify continued development work on magnetic suspension and balance systems (MSBS) by NASA. The effort involved preparation of a brief technical description of magnetic suspension and balance systems, design of a survey form asking specific questions about the role of the MSBS in satisfying future testing requirements, selecting nine major aeronautics companies to which the description and survey forms were sent, and visiting the companies and discussing the survey to obtain greater insight to their response to the survey. Evaluation and documentation of the survey responses and recommendations which evolved from the study are presented.

Upgrade of the TITAN EBIT High Voltage Operation

NASA Astrophysics Data System (ADS)

Foster, Matt; Titan Collaboration

2016-09-01

TRIUMF's Ion Trap for Atomic and Nuclear science (TITAN) is a setup dedicated to highly precise mass measurements of short-lived isotopes down to 10ms. TITAN's Electron Beam Ion Trap (EBIT) is a charge breeder integrated into the setup to perform in-trap decay spectroscopy of highly charged ions and increase the precision of mass measurements. In its previous configuration TITAN's EBIT could not fulfil its maximum design specification due to high voltage safety restrictions, limiting its obtainable charge states. A recently completed upgrade of the high voltage operation that will allow the EBIT to fulfil its design specification and achieve higher charge states for heavier species is undergoing preliminary tests with stable beam. Simulations were performed to optimise the injection and extraction efficiency at high voltage and initial tests have involved using a Ge detector to identify x-rays produced by charge breeding stable ions. Future work comprises exploring electron capture rates of Ne-, He- and H-like charge states of 64Cu and higher masses, which were not previously accessible. The function of the EBIT within the TITAN setup, the work carried out on the upgrade thus far and its scope for future work will be presented.

Development of a Non-Contact, Inductive Depth Sensor for Free-Surface, Liquid-Metal Flows

NASA Astrophysics Data System (ADS)

Bruhaug, Gerrit; Kolemen, Egemen; Fischer, Adam; Hvasta, Mike

2017-10-01

This paper details a non-contact based, inductive depth measurement system that can sit behind a layer of steel and measure the depth of the liquid metal flowing over the steel. Free-surface liquid metal depth measurement is usually done with invasive sensors that impact the flow of the liquid metal, or complex external sensors that require lasers and precise alignment. Neither of these methods is suitable for the extreme environment encountered in the diverter region of a nuclear fusion reactor, where liquid metal open channel flows are being investigated for future use. A sensor was developed that used the inductive coupling of a coil to liquid metal to measure the height of the liquid metal present. The sensor was built and tested experimentally, and modeled with finite element modeling software to further understand the physics involved. Future work will attempt to integrate the sensor into the Liquid Metal eXperiment (LMX) at the Princeton Plasma Physics Laboratory for more refined testing. This work was made possible by funding from the Department of Energy for the Summer Undergraduate Laboratory Internship (SULI) program. This work is supported by the US DOE Contract No.DE-AC02-09CH11466.

Purpose For work disability research to have an impact on employer policies and practices it is important for such research to acknowledge and incorporate relevant aspects of the workplace. The goal of this article is to summarize recent theoretical and methodological advances in the field of Implementation Science, relate these to research of employer disability management practices, and recommend future research priorities. Methods The authors participated in a year-long collaboration culminating in an invited 3-day conference, "Improving Research of Employer Practices to Prevent Disability", held October 14-16, 2015, in Hopkinton, MA, USA. The collaboration included a topical review of the literature, group conference calls to identify key areas and challenges, drafting of initial documents, review of industry publications, and a conference presentation that included feedback from peer researchers and a question/answer session with a special panel of knowledge experts with direct employer experience. Results A 4-phase implementation model including both outer and inner contexts was adopted as the most appropriate conceptual framework, and aligned well with the set of process evaluation factors described in both the work disability prevention literature and the grey literature. Innovative interventions involving disability risk screening and psychologically-based interventions have been slow to gain traction among employers and insurers. Research recommendations to address this are : (1) to assess organizational culture and readiness for change in addition to individual factors; (2) to conduct process evaluations alongside controlled trials; (3) to analyze decision-making factors among stakeholders; and (4 ) to solicit input from employers and insurers during early phases of study design. Conclusions Future research interventions involving workplace support and involvement to prevent disability may be more feasible for implementation if organizational decision-making factors are imbedded in research designs and interventions are developed to take account of these influences.

Hazard scenarios provide emergency managers and others with information to help them prepare for future disasters. The SAFRR Tsunami Scenario, published in 2013, modeled a hypothetical but plausible tsunami, created by an Mw9.1 earthquake occurring offshore from the Alaskan peninsula, and its impacts on the California coast. It presented the modeled inundation areas, current velocities in key ports and harbors, physical damage and repair costs, economic consequences, environmental impacts, social vulnerability, emergency management, and policy implications for California associated with the scenario tsunami. The intended users were those responsible for making mitigation decisions before and those who need to make rapid decisions during future tsunamis. It provided the basis for many exercises involving, among others, NOAA, the State of Washington, several counties in California, and the National Institutes of Health. The scenario led to improvements in the warning protocol for southern California and highlighted issues that led to ongoing work on harbor and marina safety. Building on the lessons learned in the SAFRR Tsunami Scenario, another tsunami scenario is being developed with impacts to Hawaii and to the source region in Alaska, focusing on the evacuation issues of remote communities with primarily shore parallel roads, and also on the effects of port closures. Community exposure studies in Hawaii (Ratliff et al., USGS-SIR, 2015) provided background for selecting these foci. One complicated and important aspect of any hazard scenario is defining the source event. The USGS is building collaborations with the National Tsunami Hazard Mitigation Program (NTHMP) to consider issues involved in developing a standardized set of tsunami sources to support hazard mitigation work. Other key USGS-NTHMP collaborations involve population vulnerability and evacuation modeling.

Is it possible to establish (at short, medium and long term) future work conditions or expected work conditions for Colombian people considering upcoming work technologies? Is it possible to anticipate future work desirable work conditions for Colombian people in order to plan (foresee?) work technologies? These questions guided this research and they point to an action thesis and to a reaction one in this context of work crisis. Even though a work technology establishes where, when, how, who, who with, and using what element work is done, it also establishes certain work conditions. Besides, multiple forms of considering and deconstructing past have been created from many disciplines. However, in order to foresee or construct work technologies requires a different perspective for looking further. This research has been carried out considering other disciplines points of view regarding Future Studies and Future Thinking Studies. This research has the purpose of finding future paths for Future Thinking Studies from ergonomics point of view in this moment of global work crisis we are going through.

Working memory and arithmetic calculation in children: the contributory roles of processing speed, short-term memory, and reading.

PubMed

Berg, Derek H

2008-04-01

The cognitive underpinnings of arithmetic calculation in children are noted to involve working memory; however, cognitive processes related to arithmetic calculation and working memory suggest that this relationship is more complex than stated previously. The purpose of this investigation was to examine the relative contributions of processing speed, short-term memory, working memory, and reading to arithmetic calculation in children. Results suggested four important findings. First, processing speed emerged as a significant contributor of arithmetic calculation only in relation to age-related differences in the general sample. Second, processing speed and short-term memory did not eliminate the contribution of working memory to arithmetic calculation. Third, individual working memory components--verbal working memory and visual-spatial working memory--each contributed unique variance to arithmetic calculation in the presence of all other variables. Fourth, a full model indicated that chronological age remained a significant contributor to arithmetic calculation in the presence of significant contributions from all other variables. Results are discussed in terms of directions for future research on working memory in arithmetic calculation.

This study draws on data from focus groups involving 50 young people from low-income families in Hong Kong to investigate their school-to-work experiences. In line with the ecological–developmental perspective, our results show that contextual influences, including lower levels of parental involvement and lack of opportunities for further education or skill development, constrain both the formulation and pursuit of educational and career goals. In contrast, service use and supportive interactions with parents and non-family adults were found to help young people find a career direction and foster more adaptive transition. Furthermore, our results indicate a striking difference in intrapersonal agency and coping styles between youths who were attending further education or engaged in jobs with career advancement opportunities and those who were not. We discuss the implications of our findings, both for future research and for policy development to enhance the school-to-work transition of economically disadvantaged young people. PMID:25364087

Although United States employment policies have increased support for people with disabilities working in community settings, the unemployment rate for this population remains very high, particularly for people with intellectual or developmental disabilities. Research shows that job developers (direct support professionals who assist people with disabilities to secure, maintain, and advance in employment) are critical to achieving quality employment outcomes. However, the extent to which job developers use practices that are considered promising in their field (such as engaging families) is not well known. This brief report summarizes findings from a qualitative study about the extent to which job developers use the recommended promising practices when working with individuals and family members. Qualitative analysis identified the following themes among job developers: factors affecting family involvement, perceptions of family involvement, and the influence of expectation on strategies. The field of job development faces a challenge common to many professions: translating research on best practices to those who need this knowledge the most and can use it to greatest effect. Future research should address how community rehabilitation providers (CRPs) communicate about and instill best practices, including effective family engagement, within their organizations. © 2013 John Wiley & Sons Ltd.

There is a need for a clear definition of exacerbations used in clinical trials in patients with bronchiectasis. An expert conference was convened to develop a consensus definition of an exacerbation for use in clinical research.A systematic review of exacerbation definitions used in clinical trials from January 2000 until December 2015 and involving adults with bronchiectasis was conducted. A Delphi process followed by a round-table meeting involving bronchiectasis experts was organised to reach a consensus definition. These experts came from Europe (representing the European Multicentre Bronchiectasis Research Collaboration), North America (representing the US Bronchiectasis Research Registry/COPD Foundation), Australasia and South Africa.The definition was unanimously approved by the working group as: a person with bronchiectasis with a deterioration in three or more of the following key symptoms for at least 48 h: cough; sputum volume and/or consistency; sputum purulence; breathlessness and/or exercise tolerance; fatigue and/or malaise; haemoptysis AND a clinician determines that a change in bronchiectasis treatment is required.The working group proposes the use of this consensus-based definition for bronchiectasis exacerbation in future clinical research involving adults with bronchiectasis.

Johannsen, C. J.; Landgrebe, D. A.

1994-01-01

This grant was funded as a part of a program in which both research and educational impact were intended. Research work under this grant is directed at the understanding and use of future hyperspectral data such as that from imaging spectrometers. Specifically, the objectives of the work were: to prepare suitable means for analyzing data from sensors which have large numbers of spectral bands, to advance the fundamental understanding of the manner in which soils and vegetative materials reflect high spectral resolution optical wavelength radiation, and to maximize the impact of the results on the educational community. Over the life of the grant, the work has thus involved basic earth science research and information system technique understanding and development in a mutually supportive way. However, during the later years it became necessary to focus the work primarily on the first and last areas, due to a steadily decreasing level of effort.

2010-09-01

Over the past 50 years, significant improvements in cardiac surgical care have been achieved. Nevertheless, surgical errors that significantly impact patient safety continue to occur. In order to further improve surgical outcomes, patient safety programs must focus on rectifying work system factors in the operating room (OR) that negatively impact the delivery of reliable surgical care. The goal of this paper is to provide an integrative review of specific work system factors in the OR that may directly impact surgical care processes, as well as the subsequent recommendations that have been put forth to improve surgical outcomes and patient safety. The important role that surgeons can play in facilitating work system changes in the OR is also discussed. The paper concludes with a discussion of the challenges involved in assessing the impact that interventions have on improving surgical care. Opportunities for future research are also highlighted throughout the paper. 2010 Elsevier Ltd. All rights reserved.

Skorstad, Gordon; Forbus, Ken

1989-01-01

One goal of qualitative physics is to capture the tacit knowledge of engineers and scientists. It is shown how Qualitative Process theory can be used to express concepts of engineering thermodynamics. In particular, it is shown how to integrate qualitative and quantitative knowledge to solve textbook problems involving thermodynamic cycles, such as gas turbine plants and steam power plants. These ideas were implemented in a program called SCHISM. Its analysis of a sample textbook problem is described and plans for future work are discussed.

The attraction of physics for women in Malaysia

Zakaria, R.; Norizan, S. F.; Latif, A. A.

2013-03-01

We report the continuity of interest of women in physics in Malaysia from the secondary school level through the undergraduate and graduate levels and involvement in the working environment. Positive developments are obvious as the percentage of women in top management positions in the public sector has increased from 19% in 2004 to 25% in June 2010. To increase this percentage in the future, we are analyzing the cause of "loss of interest" at the undergraduate's level to pursue a career in a physics-related field.

“Hidden” threats to science education

Many readers of Eos are involved with education. Most would agree that what happens at precollege levels will ultimately affect the geoscience profession; after all, future scientists are today's precollege students. While a growing number of scientists are working to improve the quality of precollege programs, only a few are addressing what we term the "hidden" threats to science education. Hidden threats have nothing to do with scientific content; rather, they result from social, political, and bureaucratic forces operating within and outside of schools and universities.

A Space Transportation System that involves the reusable Space Shuttle offers mankind's next great frontier. The country and the NASA must approach this potential opportunity with an open mind for new ideas and concepts in operations management, business principles, and sensitivity to cost. Our long term future in this new frontier will depend as much on our success in these areas as on our technological successes. This paper attempts to provide, for people with a working understanding of current ground operations, some examples of these evolving concepts.

Additive manufacturing for steels: a review

NASA Astrophysics Data System (ADS)

Zadi-Maad, A.; Rohib, R.; Irawan, A.

2018-01-01

Additive manufacturing (AM) of steels involves the layer by layer consolidation of powder or wire feedstock using a heating beam to form near net shape products. For the past decades, the AM technique reaches the maturation of both research grade and commercial production due to significant research work from academic, government and industrial research organization worldwide. AM process has been implemented to replace the conventional process of steel fabrication due to its potentially lower cost and flexibility manufacturing. This paper provides a review of previous research related to the AM methods followed by current challenges issues. The relationship between microstructure, mechanical properties, and process parameters will be discussed. Future trends and recommendation for further works are also provided.

1989-12-01

Federal statutory and case law protecting the rights of individuals with disabilities has had a major impact in expanding the occupational options for mentally and physically impaired employees. One serendipitous result of these protections has been the expansion of job opportunities for psychologists in business and industry. This article examines important federal laws and regulations pertaining to the employment rights of the handicapped worker and emphasizes the intricacies involved for psychologists who work in the employee assistance field or who consult with management. The expansion of vocational options for psychologists working with business is traced, and future prospects for psychologists in this area are explored.

Little is known about female sex workers' daily lives or emotional relationships. Using relational-cultural theory, this study explored the relationship dynamics between sex workers and their intimate partners in Kumasi, Ghana. We collected qualitative data from 37 male intimate partners through 24 in-depth interviews and two focus group discussions (FGDs) with 13 male partners. We also conducted three FGDs with 20 women involved in sex work. Relationships between sex workers and their intimate partners were mutual, reciprocal and transactional. Male partners provided protection for financial support, a place to sleep and intimacy. Both men and women described their relationships in terms of friendship, love and a hopeful future. Women were reluctant to quit sex work because they depended on it for income. Most respondents did not use condoms in these romantic relationships, citing trust, love, faithfulness and commitment. Both men and women described high levels of violence in their relationships. The context of sex work heightens vulnerability but also appears to facilitate resilience and creative coping strategies. The relational dynamics between sex workers and their intimate partners in Ghana merit further exploration to examine the extent to which women involved in sex work hold and exert power within these relationships.

Current health care systems are not optimally designed to meet the needs of our aging populations. First, the fragmentation of care often results in discontinuity of care that can undermine the quality of care provided. Second, patient involvement in care decisions is not sufficiently facilitated. To describe the development and the content of a program aimed at: (1) facilitating self-management and shared decision making by frail older people and informal caregivers, and (2) reducing fragmentation of care by improving collaboration among professionals involved in the care of frail older people through a combined multidisciplinary electronic health record (EHR) and personal health record (PHR). We used intervention mapping to systematically develop our program in six consecutive steps. Throughout this development, the target populations (ie, professionals, frail older people, and informal caregivers) were involved extensively through their participation in semi-structured interviews and working groups. We developed the Health and Welfare Information Portal (ZWIP), a personal, Internet-based conference table for multidisciplinary communication and information exchange for frail older people, their informal caregivers, and professionals. Further, we selected and developed methods for implementation of the program, which included an interdisciplinary educational course for professionals involved in the care of frail older people, and planned the evaluation of the program. This paper describes the successful development and the content of the ZWIP as well as the strategies developed for its implementation. Throughout the development, representatives of future users were involved extensively. Future studies will establish the effects of the ZWIP on self-management and shared decision making by frail older people as well as on collaboration among the professionals involved.

Cathey, H.; Hottman, S.; Hansen, K.

The NASA Suborbital Center of Excellence is charting new territory. From an idea to promote science and engineering education and outreach, the Suborbital Center of Excellence is working toward the objective of increasing numbers of college graduates choosing a career in suborbital programs. Approaches to excite university students to want to pursue these careers through relevant and useful work experiences will be highlighted. Suborbital platforms include balloons, sounding rockets, research aircraft (manned and remotely piloted vehicles) and small satellites. Key components of this are the Suborbital Center of Excellence co-op program and the support of Engineering ``Capstone'' projects. A number of these projects and programs have been supported during the past year. Highlights of these student hands-on learning experiences will be presented. The projects have included diverse projects ranging from work on a power beaming demonstration and autonomous aircraft control logic to the development of light weight pressure vessels for balloon flights based on ULDB spin-off technology, and balloon drop sonde development. Preparing these future Scientists and Engineers involves the investment of time, energy, and resources. The Suborbital Center of Excellence is uniquely positioned to do this. Future programs and initiatives will be presented. The Suborbital Center of Excellence is evolving, meeting the needs to promote science and engineering education and outreach. Educational outreach initiatives for young children to university students will also be presented. These include hands-on experiments, demonstrations, and suborbital educational materials.

Towards an Earth System Knowledge Environment Designed to Promote More Usable Science

NASA Astrophysics Data System (ADS)

Killeen, T. L.

2006-12-01

It is abundantly clear that fundamental decisions about how to manage future human society will need to be informed by quantitative scientific analyses of processes, options, impacts, and responses. In fact, one could argue that the human experience into the foreseeable future will increasingly be tied to the integrating of information, understanding, and experiences to create knowledge and with it solutions to emerging problems as well as opportunities for further progress. This is particularly true for the Geosciences. Our scientific field, and by extension our Union, has a special responsibility for informing policy makers and the public about how the earth system functions and about the relationship between environmental stressors and human activities. In this regard, a greatly improved working interface between natural and social scientists is needed. In this talk, I argue that something like an "Earth System Knowledge Environment" or "Earth System Collaboratory" should be developed using modern information technologies to encapsulate and make accessible existing and emerging interdisciplinary knowledge of particular use to decision makers. Such a "work place" should be open to all and could provide access to observations, models and theories in ways that more easily allow for credible scientific understanding to be translated into policy options at all levels. Examples of fledgling efforts along these lines will be cited in areas such as severe weather impacts and climate change. The challenges involved in creating more usable scientific knowledge are, of course, quite significant and include major issues such as: institutional impediments to interdisciplinary research, the role of proprietary interests, the difficulties involved in working across the natural/social science boundary, and the challenge of developing the kind of human capital needed to effectively close the gap between good science and public policy.

The Terrestrial Planet Finder (TPF) coronagraph study involves exploring the technologies that enable a coronagraph style instrument to image and characterize earth-like planets orbiting nearby stars. Testbeds have been developed to demonstrate the emerging technologies needed for this effort and an architecture study has resulted in designs of a facility that will provide the environment needed for the technology to function in this role. A broad community of participants is involved in this work through studies, analyses, fabrication of components, and participation in the design effort. The scope of activities - both on the technology side and in the architecture study side - will be presented in this paper. The status and the future plans of the activities will be reviewed.

Particulate contamination is of concern in a variety of environments. This issue is especially important in confined spaces with highly controlled atmospheres such as space exploration vehicles involved in extraterrestrial surface missions. Lunar dust was a significant challenge for the Apollo astronauts and will be of greater concern for longer duration, future missions. Passive mitigation strategies, those not requiring external energy, may decrease some of these concerns, and have been investigated in this work. A myriad of approaches to modify the surface chemistry and topography of a variety of substrates was investigated. These involved generation of novel materials, photolithographic techniques, and other template approaches. Additionally, single particle and multiple particle methods to quantitatively evaluate the particle-substrate adhesion interactions were developed.

The impact of criminal justice involvement on victims' mental health.

Parsons, Jim; Bergin, Tiffany

2010-04-01

The aftermath of violent crime can leave victims with persistent emotional and mental health problems. Although research has shown the potential benefits of prosecuting cases through the courts, there is also a substantial literature that suggests that common features of the criminal justice system can exacerbate the impact of the initial crime, leading to a secondary victimization. The authors present a review of the research on the positive and negative impact of criminal justice involvement, and common points of failure in the efforts of justice institutions to meet the needs of victims. They conclude with recommendations for future work, including the need for research on restorative justice, victim impact statements, court notification systems, victim services, and victim advocates.

We obtain the bright similariton solutions for generalized inhomogeneous nonlinear Schrödinger equation (GINLSE) which governs the pulse propagation in a tapered graded index diffraction decreasing waveguide (DDW). The exact solutions have been worked out by employing similarity transformations which involve the mapping of the GINLSE to standard NLSE for the certain conditions of the parameters. By making use of the exact analytical solutions, we have investigated the dynamical behavior of optical similariton pairs and have suggested the methods to control them as they propagate through DDW. Moreover, pulse width of similariton is controlled through various profiles. These results are helpfulmore » to understand the similaritons in DDW and can be potentially useful for future experiments in optical communications which involve optical amplifiers and long-haul telecommunication networks.« less

Partnering with migrant friendly organizations: a case example from a Canadian school of nursing.

PubMed

Hickey, Jason; Gagnon, Anita J; Merry, Lisa

2010-01-01

Worldwide immigration to many high-income countries suggests that these countries' health care systems must become responsive to a more diverse population. Experiences working with newly arrived populations can provide healthcare students, professionals, and teachers, with valuable insight into the health and social conditions these newcomers face in both source and receiving countries. One way to gain this experience may be by developing partnerships between schools of nursing in receiving countries and international health organizations working in areas that are major migrant source regions for these countries. In this paper, we use a case example to describe, the process of identifying international, migrant-focused organizations, and the steps involved in developing partnerships with these organizations, for the implementation of a migrant health component in health professional curricula. After creating a set of criteria to evaluate partnership potential, we identified a list of international health organizations with whom we thought a partnership might be possible. Following application of our criteria, future work is being pursued with two organizations. Potential implications of this partnership include benefits to all parties involved that may help us move towards increased population and public health capacity.

Toward Predictive Theories of Nuclear Reactions Across the Isotopic Chart: Web Report

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

Escher, J. E.; Blackmon, J.; Elster, C.

Recent years have seen exciting new developments and progress in nuclear structure theory, reaction theory, and experimental techniques, that allow us to move towards a description of exotic systems and environments, setting the stage for new discoveries. The purpose of the 5-week program was to bring together physicists from the low-energy nuclear structure and reaction communities to identify avenues for achieving reliable and predictive descriptions of reactions involving nuclei across the isotopic chart. The 4-day embedded workshop focused on connecting theory developments to experimental advances and data needs for astrophysics and other applications. Nuclear theory must address phenomena from laboratorymore » experiments to stellar environments, from stable nuclei to weakly-bound and exotic isotopes. Expanding the reach of theory to these regimes requires a comprehensive understanding of the reaction mechanisms involved as well as detailed knowledge of nuclear structure. A recurring theme throughout the program was the desire to produce reliable predictions rooted in either ab initio or microscopic approaches. At the same time it was recognized that some applications involving heavy nuclei away from stability, e.g. those involving fi ssion fragments, may need to rely on simple parameterizations of incomplete data for the foreseeable future. The goal here, however, is to subsequently improve and refine the descriptions, moving to phenomenological, then microscopic approaches. There was overarching consensus that future work should also focus on reliable estimates of errors in theoretical descriptions.« less

Reducing physical size limits for low-frequency horn loudspeaker systems

NASA Astrophysics Data System (ADS)

Honeycutt, Richard Allison

From 1881 until the present day, many excellent scholars have studied acoustic horns. This dissertation begins by discussing over eighty results of such study. Next, the methods of modeling horn behavior are examined with an emphasis on the prediction of throat impedance. Because of the time constraints in a product-design environment, in which the results of this study may be used, boundary-element and cascaded-section types of analysis were not considered due to their time intensiveness. Of the methods studied, an analytical process based upon Olson's adaptation of Webster's analysis is selected as the most accurate of the rapid methods, although other good methods exist. Reasons and extent of inaccuracy are discussed. The concept of interleaved horn loading is introduced: it involves using two horns of different parameters, fed by a single driver, with a view toward interleaving and thus smoothing the impedance peaks of the separate horns to produce a smoother response. The validity of the technique is demonstrated both theoretically and practically. Then the reactance annulling technique is explained and tested experimentally. It is found to work well, but the exact parameter values involved are not found to be critical. Finally, the considerations involved in building a practical working system are discussed, and a preliminary working model reviewed. Future work could be directed toward finding the optimum parameter values for the two "parallel horns" whose impedances are to be interleaved, as well as the system parameters that determine these optimum values. Also, further experimental investigation or ported loading of the back air chamber would be useful.

NSF-Sponsored Summit on the Future of Undergraduate Geoscience Education: outcomes

Mosher, S.

2014-12-01

The NSF-sponsored Summit on the Future of Undergraduate Geoscience Education made major progress toward developing a collective community vision for the geosciences. A broad spectrum of the geoscience education community, ~200 educators from research universities/four and two year colleges, focused on preparation of undergraduates for graduate school and future geoscience careers, pedagogy, use of technology, broadening participation/retention of underrepresented groups, and preparation of K-12 science teachers. Participants agreed that key concepts, competencies and skills learned throughout the curriculum were more important than specific courses. Concepts included understanding Earth as complex, dynamic system, deep time, evolution of life, natural resources, energy, hazards, hydrogeology, surface processes, Earth materials and structure, and climate change. Skills/competencies included ability to think spatially and temporally, reason inductively and deductively, make and use indirect observations, engage in complex open, coupled systems thinking, and work with uncertainty, non-uniqueness, and incompleteness, as well as critical thinking, problem solving, communication, and ability to think like a scientist and continue to learn. Successful ways of developing these include collaborative, integrative projects involving teams, interdisciplinary projects, fieldwork and research experiences, as well as flipped classrooms and integration and interactive use of technology, including visualization, simulation, modeling and analysis of real data. Wider adoption of proven, effective best practices is our communities' main pedagogical challenge, and we focused on identifying implementation barriers. Preparation of future teachers in introductory and general geoscience courses by incorporating Next Generation Science Standards and using other sciences/math to solve real world geoscience problems should help increase diversity and number of future geoscientists and geoscience literacy. We also identified key elements of successful programs that attract and retain underrepresented groups, including providing financial support, reaching out to students in their communities, involving community members, incorporating role models, and mentoring.

Combustion of interacting droplet arrays in a microgravity environment

Dietrich, Daniel L.; Haggard, John B.

1993-01-01

This research program involves the study of one and two dimensional arrays of droplets in a buoyant-free environment. The purpose of the work is to extend the database and theories that exist for single droplets into the regime where droplet interactions are important. The eventual goal being to use the results of this work as inputs to models on spray combustion where droplets seldom burn individually; instead the combustion history of a droplet is strongly influenced by the presence of the neighboring droplets. The emphasis of the present investigation is experimental, although comparison will be made to existing theoretical and numerical treatments when appropriate. Both normal gravity and low gravity testing will be employed, and the results compared. The work to date will be summarized in the next section, followed by a section detailing the future plans.

Human-Agent collaboration is increasingly important. Not only do high-profile activities such as NASA missions to Mars intend to employ such teams, but our everyday activities involving interaction with computational devices falls into this category. In many of these scenarios, we are expected to trust that the agents will do what we expect and that the agents and humans will work together as expected. But how can we be sure? In this paper, we bring together previous work on the verification of multi-agent systems with work on the modelling of human-agent teamwork. Specifically, we target human-robot teamwork. This paper provides an outline of the way we are using formal verification techniques in order to analyse such collaborative activities. A particular application is the analysis of human-robot teams intended for use in future space exploration.

2015-11-01

This cross-sectional study evaluated working conditions and the occurrence of self-reported musculoskeletal symptoms among 251 Iranian sewing machine operators. A questionnaire and direct observations of working postures using the rapid upper limb assessment (RULA) method were used. A high prevalence of musculoskeletal symptoms, particularly in the neck/shoulders, back and hands/wrists were found. The mean RULA grand score of 5.7 highlighted a poor sewing workstation design and indicated that most operators (with posture assessed at action level 3) needed an investigation and changes in their working habits soon. Work-related factors (including number of years worked as an operator, prolonged working hours per shift, long duration of sitting work without a break, feeling pressure due to work and working postures) and individual factors (including age, gender, BMI and regular sport/physical activities) were associated with musculoskeletal symptoms in multiple logistic regression models. The findings add to the understanding of working conditions of those jobs involving sewing activities and emphasise the need for ergonomic interventions to reduce musculoskeletal symptoms in the future.

The Student Outreach with Renewable Energy Technology (SORET) program is an education program involving three Historically Black Colleges and Universities and NASA's John H. Glenn Research Center at Lewis Field. These three universities; Central State University (CSU), Savannah State University (SSU) and Wilberforce University (WU) are working together with NASA Glenn to use the theme of renewable energy to improve the science, engineering and technology education of minority students and to attract minority students to these fields. In this vein, a renewable energy laboratory course is being offered at WU with the goal of giving the students of WU and CSU hands on experiences. As part of this course, the students are constructing solar light posts for a local high school with a high minority population. A Physics teacher from this school and some of his high school students are involved with this project. A lecture course on energy systems and sustainability is being developed by SSU to be delivered via distance reaming to the other institutions. Summer activities are being planned at all three institutions involving student projects in renewable energy. For example, WU students will work on a study of the synthesis and properties of photovoltaic materials. In addition, CSU will present a weeklong summer program to high school students with the assistance of WU. This presentation will focus on the student involvement and achievements in the educational area to date and plot the future course of this program.

The use of computers, especially for virtual reality (VR), to understand, assess, and treat various mental health problems has been developed for the last decade, including application for phobia, post-traumatic stress disorder, attention deficits, and schizophrenia. However, the number of VR tools addressing obsessive-compulsive disorder (OCD) is still lacking due to the heterogeneous symptoms of OCD and poor understanding of the relationship between VR and OCD. This article reviews the empirical literatures for VR tools in the future, which involve applications for both clinical work and experimental research in this area, including examining symptoms using VR according to OCD patients' individual symptoms, extending OCD research in the VR setting to also study behavioral and physiological correlations of the symptoms, and expanding the use of VR for OCD to cognitive-behavioral intervention.

Electronic Medical Records (EMRs), Epidemiology, and Epistemology: Reflections on EMRs and Future Pediatric Clinical Research

PubMed Central

Wasserman, Richard C.

2011-01-01

Electronic medical records (EMRs) are increasingly common in pediatric patient care. EMR data represent a relatively novel and rich resource for clinical research. The fact, however, that pediatric EMR data are collected for the purposes of clinical documentation and billing rather than research creates obstacles to their use in scientific investigation. Particular issues include accuracy, completeness, comparability between settings, ease of extraction, and context of recording. Although these problems can be addressed through standard strategies for dealing with partially accurate and incomplete data, a longer term solution will involve work with pediatric clinicians to improve data quality. As research becomes one of the explicit purposes for which pediatricians collect EMR data, the pediatric clinician will play a central role in future pediatric clinical research. PMID:21622040

Explaining the Relationship between Employment and Juvenile Delinquency.

2010-11-28

Most criminological theories predict an inverse relationship between employment and crime, but teenagers' involvement in paid work during the school year is positively correlated with delinquency and substance use. Whether the work-delinquency association is causal or spurious has long been debated. This study estimates the effect of paid work on juvenile delinquency using longitudinal data from the national Monitoring the Future project. We address issues of spuriousness by using a two-level hierarchical model to estimate the relationships of within-individual changes in juvenile delinquency and substance use to those in paid work and other explanatory variables. We also disentangle effects of actual employment from preferences for employment to provide insight about the likely role of time-varying selection factors tied to employment, delinquency, school engagement, and leisure activities. Whereas causal effects of employment would produce differences based on whether and how many hours respondents worked, we found significantly higher rates of crime and substance use among non-employed youth who preferred intensive versus moderate work. Our findings suggest the relationship between high-intensity work and delinquency results from preexisting factors that lead youth to desire varying levels of employment.

Contagious flexibility? A study on whether schedule flexibility facilitates work-life enrichment.

PubMed

Pedersen, Vivi Bach; Jeppesen, Hans Jeppe

2012-08-01

Schedule flexibility defines an important generating resource for work-life enrichment; however, our knowledge about how such spillovers take place is limited. This multiple case study examines how workers from different working time contexts with varying levels of schedule flexibility experience work-life interplay. Given the adopted explorative design, it is important to interpret the findings in a tentative light. Nonetheless, the study offers important insight into work-life enrichment that may guide future research in this field. The findings indicate that schedule flexibility may act as a boundary-spanning resource owing to the agency potential it offers workers. Thus, it seemed that flexible schedule opportunities enabled workers to engage more fully in personal life activities, which in turn had a positive influence on their work involvement through positive affect. Such positive role engagements appeared, however, to be greatly determined by workers' boundary management and by time conditions of work and family. In conclusion, the major findings and limitation of the study are discussed against existing research and theory. © 2012 The Authors.

The paper describes the authors' work in the area of health informatics (HI) education involving emerging health information technologies. A range of information technologies promise to modernize health care. Foremost among these are electronic health records (EHRs), which are expected to significantly improve and streamline health care practice. Major national and international efforts are currently underway to increase EHR adoption. However, there have been numerous issues affecting the widespread use of such information technology, ranging from a complex array of technical problems to social issues. This paper describes work in the integration of information technologies directly into the education and training of HI students at both the undergraduate and graduate level. This has included work in (a) the development of Web-based computer tools and platforms to allow students to have hands-on access to the latest technologies and (b) development of interdisciplinary educational models that can be used to guide integrating information technologies into HI education. The paper describes approaches that allow for remote hands-on access by HI students to a range of EHRs and related technology. To date, this work has been applied in HI education in a variety of ways. Several approaches for integration of this essential technology into HI education and training are discussed, along with future directions for the integration of EHR technology into improving and informing the education of future health and HI professionals.

Family caregivers are regularly involved in cancer consultations and treatment decision-making (DM). Yet there is limited conceptual description of caregiver influence/involvement in DM. To address this, an empirically-grounded conceptual framework of triadic DM (TRIO Framework) and corresponding graphical aid (TRIO Triangle) were developed. Jabareen's model for conceptual framework development informed multiple phases of development/validation, incorporation of empirical research and theory, and iterative revisions by an expert advisory group. Findings coalesced into six empirically-grounded conceptual insights: i) Caregiver influence over a decision is variable amongst different groups; ii) Caregiver influence is variable within the one triad over time; iii) Caregivers are involved in various ways in the wider DM process; iv) DM is not only amongst three, but can occur among wider social networks; v) Many factors may affect the form and extent of caregiver involvement in DM; vi) Caregiver influence over, and involvement in, DM is linked to their everyday involvement in illness care/management. The TRIO Framework/Triangle may serve as a useful guide for future empirical, ethical and/or theoretical work. This Framework can deepen clinicians's and researcher's understanding of the diverse and varying scope of caregiver involvement and influence in DM. Copyright © 2017 Elsevier B.V.

Introduction Outcome assessment is a central issue in work disability prevention research. The goal of this paper was to (1) ascertain the most salient workplace outcomes; (2) evaluate the congruence between business and science perspectives; (3) illustrate new perspectives on assessing longitudinal outcomes; and (4) provide recommendations for advancing outcome evaluation in this area of research. Methods The authors participated in a year-long collaboration that culminated in a sponsored 3-day conference, "Improving Research of Employer Practices to Prevent Disability", held October 14-16, 2015, in Hopkinton, MA, USA. The collaboration included a topical review of the literature, group conference calls to identify key areas and challenges, drafting of initial documents, review of industry publications, and a conference presentation that included feedback from peer researchers and a question/answer session with a special panel of knowledge experts with direct employer experience. Results Numerous workplace work-disability prevention outcome measures were identified. Analysis indicated that their applicability varied depending on the type of work disability the worker was experiencing. For those who were working, but with health-related work limitations (Type 1), predominant outcomes were measures of productivity, presenteeism, and work-related limitations. For those who were off work due to a health condition (Type 2), predominant outcomes were measures of time off work, supervisor/employee interactions, and return-to-work (RTW) preparation. For those who had returned to work (Type 3), predominant outcomes were measures of presenteeism, time until RTW, percentage of work resumption, employment characteristics, stigma, work engagement, co-worker interactions, and sustained or durable RTW. For those who had withdrawn from the labor force (Type 4), predominant outcomes were cost and vocational status. Discussion Currently available measures provide a good basis to use more consistent outcomes in disability prevention in the future. The research area would also benefit from more involvement of employers as stakeholders, and multilevel conceptualizations of disability outcomes.

A new approach for evaluating flexible working hours.

Recent studies on flexible working hours show at least some of these working time arrangements seem to be associated with impairing effects of health and well-being. According to available evidence, variability of working hours seems to play an important role. The question, however, is how this variability can be assessed and used to explain or predict impairments. Based on earlier methods used to assess shift-work effects, a time series analysis approach was applied to the matter of flexible working hours. Data on the working hours of 4 week's length of 137 respondents derived from a survey on flexible work hours involving 15 companies of different production and service sectors in Germany were converted to time series and analyzed by spectral analysis. A cluster analysis of the resulting power spectra yielded 5 clusters of flexible work hours. Analyzing these clusters for differences in reported impairments showed that workers who showed suppression of circadian and weekly rhythms experienced severest impairments, especially in circadian controlled functions like sleep and digestion. The results thus indicate that analyzing the periodicity of flexible working hours seems to be a promising approach for predicting impairments which should be investigated further in the future.

Operational Assessment of Apollo Lunar Surface Extravehicular Activity

Miller, Matthew James; Claybrook, Austin; Greenlund, Suraj; Marquez, Jessica J.; Feigh, Karen M.

2017-01-01

Quantifying the operational variability of extravehicular activity (EVA) execution is critical to help design and build future support systems to enable astronauts to monitor and manage operations in deep-space, where ground support operators will no longer be able to react instantly and manage execution deviations due to the significant communication latency. This study quantifies the operational variability exhibited during Apollo 14-17 lunar surface EVA operations to better understand the challenges and natural tendencies of timeline execution and life support system performance involved in surface operations. Each EVA (11 in total) is individually summarized as well as aggregated to provide descriptive trends exhibited throughout the Apollo missions. This work extends previous EVA task analyses by calculating deviations between planned and as-performed timelines as well as examining metabolic rate and consumables usage throughout the execution of each EVA. The intent of this work is to convey the natural variability of EVA operations and to provide operational context for coping with the variability inherent to EVA execution as a means to support future concepts of operations.

Healthcare reforms: implications for the education and training of acute and critical care nurses.

PubMed

Glen, S

2004-12-01

This paper offers a wide ranging analysis of the drivers that resulted in scrutiny of medical, nursing, and healthcare professional roles. It suggests that what is needed is a coherent vision of the future shape of the health workforce. This requires moving beyond the presumption that reforming working practices primarily involves "delegating doctors" responsibilities to nurses. The paper argues that it is self evident that the implications of changes in healthcare roles and the ability of existing professionals to function effectively in the future will require education, training, and human resource investment supportive of the changes. It suggests a clear definition of competence and a national standard to practice is essential for nurses working in acute and acute critical settings. There should therefore be a correlation between levels of practice, levels of education, and remuneration. Furthermore, education programmes for senior nurses should sit coherently alongside the education programmes required by Modernising Medical Careers. Finally, the realisation of the government's service and modernisation agenda will require a culture change within higher education institutions, postgraduate deaneries, professional organisations, workforce development confederations, and NHS trusts.

NuMI Flux Predictions for NOvA and MINERvA

Aliaga Soplin, Leonidas; Nova Collaboration; Minerva Collaboration

2017-01-01

The determination of the neutrino flux in any conventional neutrino beam presents a challenge for the current and future short and long baseline neutrino experiments. The uncertainties associated with the production and attenuation of the hadrons in the beamline materials along with those associated with the beam optics have a big effect in the knowledge of the flux. For experiments like MINERvA and NOvA, understanding the flux is crucial since it enters directly into every neutrino-nucleus cross-section measurement. The majority of this work involves predicting the neutrino flux using dedicated hadron production measurements from hadron-nucleus collisions. The predictions at the MINERvA and NOvA near detectors are presented as well as the results of incorporating in-situ MINERvA data that can provide additional constraints. These results have been fully implemented in MINERvA and they are currently use for its cross-section analysis. The implementation for NoVA is underway. The procedure and conclusions of this work will have a big impact on future hadron production experiments and on determining the flux for the upcoming DUNE experiment.

The overall aim of this paper is to draw combined, all-embracing conclusions based on a long-term multidisciplinary research programme on recycling centres in Sweden, focussing on working conditions, environment and system performance. A second aim is to give recommendations for their development of new and existing recycling centres and to discuss implications for the future design and organisation. Several opportunities for improvement of recycling centres were identified, such as design, layout, ease with which users could sort their waste, the work environment, conflicting needs and goals within the industry, and industrialisation. Combining all results from the research, which consisted of different disciplinary aspects, made it possible to analyse and elucidate their interrelations. Waste sorting quality was recognized as the most prominent improvement field in the recycling centre system. The research identified the importance of involving stakeholders with different perspectives when planning a recycling centre in order to get functionality and high performance. Practical proposals of how to plan and build recycling centres are given in a detailed checklist. Copyright © 2016 Elsevier Ltd. All rights reserved.

Proteolytic activity during senescence of plants

NASA Technical Reports Server (NTRS)

Huffaker, R. C.

1990-01-01

Although information has rapidly developed concerning the intracellular localization of plant proteins, relatively few reports concern the intracellular location of endo- and exo-proteolytic activities. Relatively few proteases have been purified, characterized, and associated with a specific cellular location. With the exception of the processing proteases involved in transport of proteins across membranes, little progress has yet been made concerning determination of in vivo products of specific proteases. Information on the turnover of individual proteins and the assessment of rate-limiting steps in pathways as proteins are turned over is steadily appearing. Since chloroplasts are the major site of both protein synthesis and, during senescence, degradation, it was important to show unambiguously that chloroplasts can degrade their own constituents. Another important contribution was to obtain evidence that the chloroplasts contain proteases capable of degrading their constituents. This work has been more tenuous because of the low activities found and the possibility of contamination by vacuolar enzymes during the isolation of organelles. The possible targeting of cytoplasmic proteins for degradation by facilitating their transport into vacuoles is a field which hopefully will develop more rapidly in the future. Information on targeting of proteins for degradation via the ubiquitin (Ub) degradation pathway is developing rapidly. Future research must determine how much unity exists across the different eukaryotic systems. At present, it has important implications for protein turnover in plants, since apparently Ub is involved in the degradation of phytochrome. Little information has been developed regarding what triggers increased proteolysis with the onset of senescence, although it appears to involve protein synthesis. Thus far, the evidence indicates that the complement of proteases prior to senescence is sufficient to carry out the observed protein degradation. This field of study has great practical implications, e.g. maintaining photosynthesis during seed-fill in order to obtain greater crop yields. The current use of stay green' variants in the populations of several crop plants to produce increased yields shows the potential for future development. The near future should see exciting discoveries in these areas of research that will have far reaching effects on the construction of transgenic plants for future research accomplishments and agricultural use.

System engineering analysis of derelict collision prevention options

McKnight, Darren S.; Di Pentino, Frank; Kaczmarek, Adam; Dingman, Patrick

2013-08-01

Sensitivities to the future growth of orbital debris and the resulting hazard to operational satellites due to collisional breakups of large derelict objects are being studied extensively. However, little work has been done to quantify the technical and operational tradeoffs between options for minimizing future derelict fragmentations that act as the primary source for future debris hazard growth. The two general categories of debris mitigation examined for prevention of collisions involving large derelict objects (rocket bodies and payloads) are active debris removal (ADR) and just-in-time collision avoidance (JCA). Timing, cost, and effectiveness are compared for ADR and JCA solutions highlighting the required enhancements in uncooperative element set accuracy, rapid ballistic launch, despin/grappling systems, removal technologies, and remote impulsive devices. The primary metrics are (1) the number of derelict objects moved/removed per the number of catastrophic collisions prevented and (2) cost per collision event prevented. A response strategy that contains five different activities, including selective JCA and ADR, is proposed as the best approach going forward.

Own aging: future time perspectives and scenarios perceived by females employed in old age care.

PubMed

Fromholt, P; Larsen, P; Snell, H

1994-04-01

This study focuses on anticipations of own aging, and the process of adaptation to aging across the life span. Future time perspectives and aging scenarios were investigated in 276 Danish females employed in old age care (aged 22 to 63 years), by use of questionnaires. Age-related differences were found regarding how far ahead subjects indicated to plan their future, increasing from about two years in subjects in their twenties and stabilizing at about ten years in older subjects. Datings of events that first initiated thinking of one's own aging increased with the age of the subjects, and some age-related patterns in the content of recalled events were found. A developmental mechanism involving reinterpretation of essential elements of aging is suggested as an explanation for these findings. A preponderance of positive scenarios suggests that optimistic anticipations of own aging may coexist with exposure to negative aspects of aging due to working experiences with disabled old people.

A systematic literature review of engineering identity: definitions, factors, and interventions affecting development, and means of measurement

Morelock, John R.

2017-11-01

Studies exploring what it means to be an engineer professionally have been conducted for decades, but have boomed in recent years. This systematic literature review aims to organise extant studies on engineering identity by coding around four key variables: (a) definitions of engineering identity, (b) factors affecting engineering identity development, (c) interventions affecting engineering identity development, and (d) means of measuring identity. In doing so, this review provides strategies for future research and educational interventions to advance work related to engineering identity. Publications were selected for inclusion by screening and appraising results obtained from databases and keywords refined through a scoping study. Derived from key findings, suggestions for future research include bridging disparate strands of engineering identity literature and incorporating more varied methodological approaches. Also from key findings, suggestions for future practice involve better connecting existing definitions of engineering identity and factors known to affect identity development with identity-related interventions.

Young people are the future of research, especially in nephrology. The prevalence of young nephrologists within the main scientific European societies varies from the 12% to 34% and the 20% of the ERA-EDTA members are less than 40 years old in 2013. Recently, the ERA-EDTA has launched a new platform, the Young Nephrologists Platform (YNP), which the aim is to become the first modern network of young nephrologists from Europe and beyond. YNP aims at promoting the aggregation of young people through modern communication channels such as social networks, blogs and through the construction of a database collecting information on attitudes and personal experiences of each young nephrologist. A mentorship program, focused and young-oriented clinical courses on hot topics and the direct involvement of young nephrologists in working groups and scientific studies are some of the other interesting initiatives driven by YNP. The future of nephrology belongs to the young and YNP could represent a good springboard for the professional growth of young nephrologists.

The grant "The Evolution of the Quasar Continuum" resulted in over 53 published referred papers and conference proceedings. The more significant of these papers are listed below, and abstracts are attached. The papers address a wide range of issues involving the evolution of quasars, their electromagnetic emissions, and their environment, from nearby low luminosity Seyfert galaxies to quasars at the highest redshifts. Primarily observational in content the work nonetheless included theoretical studies of quasar accretion disks that attempt to explain the observed time variability of quasars, and the overall 'demographics' of the quasar population. The work carried out under this grant has laid a strong foundation for ongoing and future research with AXAF, HST and other new facilities.

What is presented in this session is an unclassified review of some of the propulsion research results that are applicable for supersonic to hypersonic vehicles. Not only is a review provided for several key work areas, it also presents a viewpoint on future research directions by calling attention to cycles, components, and facilities involved in this rapidly expanding field of work.

T-38 Primary Flight Display Prototyping and HIVE Support Abstract & Summary

NASA Technical Reports Server (NTRS)

Boniface, Andrew

2015-01-01

This fall I worked in EV3 within NASA's Johnson Space Center in The HIVE (Human Integrated Vehicles & Environments). The HIVE is responsible for human in the loop testing, getting new technologies in front of astronauts, operators, and users early in the development cycle to make the interfaces more human friendly. Some projects the HIVE is working on includes user interfaces for future spacecraft, wearables to alert astronauts about important information, and test beds to simulate mock missions. During my internship I created a prototype for T-38 aircraft displays using LabVIEW, learned how to use microcontrollers, and helped out with other small tasks in the HIVE. The purpose of developing a prototype for T-38 Displays in LabVIEW is to analyze functions of the display such as navigation in a cost and time effective manner. The LabVIEW prototypes allow Ellington Field AOD to easily make adjustments to the display before hardcoding the final product. LabVIEW was used to create a user interface for simulation almost identical to the real aircraft display. Goals to begin the T-38 PFD (Primary Flight Display) prototype included creating a T-38 PFD hardware display in a software environment, designing navigation for the menu's, incorporating vertical and horizontal navigation bars, and to add a heading bug for compass controls connected to the HSI (Horizontal Situation Indicator). To get started with the project, measurements of the entire display were taken. This enabled an accurate model of the hardware display to be created. Navigation of menu's required some exploration of different buttons on the display. The T-38 simulator and aircraft were used for examining the display. After one piece of the prototype was finished, another trip of to the simulator took place. This was done until all goals for the prototype were complete. Some possible integration ideas for displays in the near future are autopilot selection, touch screen displays, and crew member preferences. Complete navigation, control, and function customization will be achievable once a display is fully developed. Other than the T-38 prototyping, I spent time learning how to design small circuits and write code for them to function. This was done by adding electronic circuit components to breadboard and microcontroller then writing code to speak to those components through the microcontroller. I went through an Arduino starter kit to build circuits and code software that allowed the hardware to act. This work was planned to assist in a lighting project this fall but another solution was discovered for the lighting project. Other tasks that I assisted with, included hands on work such as mock-up construction/removal, logic analyzer repairs, and soldering with circuits. The unique opportunity to be involved work with NASA has significantly changed my educational and career goals. This opportunity has only opened the door to my career with engineering. I have learned over the span of this internship that I am fascinated by the type of work that NASA does. My desire to work in the aerospace industry has increased immensely. I hope to return to NASA to be more involved in the advancement of science, engineering, and spaceflight. My interests for my future education and career lie in NASA’s work - pioneering the future in space exploration, scientific discovery and aeronautics research.

Excessive occupational heat exposure: a significant ergonomic challenge and health risk for current and future workers

PubMed Central

2014-01-01

Occupational heat exposure threatens the health of a worker not only when heat illness occurs but also when a worker’s performance and work capacity is impaired. Occupational contexts that involve hot and humid climatic conditions, heavy physical workloads and/or protective clothing create a strenuous and potentially dangerous thermal load for a worker. There are recognized heat prevention strategies and international thermal ergonomic standards to protect the worker. However, such standards have been developed largely in temperate western settings, and their validity and relevance is questionable for some geographical, cultural and socioeconomic contexts where the risk of excessive heat exposure can be high. There is evidence from low- and middle-income tropical countries that excessive heat exposure remains a significant issue for occupational health. Workers in these countries are likely to be at high risk of excessive heat exposure as they are densely populated, have large informal work sectors and are expected to experience substantial increases in temperature due to global climate change. The aim of this paper is to discuss current and future ergonomic risks associated with working in the heat as well as potential methods for maintaining the health and productivity of workers, particularly those most vulnerable to excessive heat exposure.

Pearson, Caroline Elizabeth; Butler, Allan J; Murray, Yaqub Paul

2018-04-21

The Vet Futures Report has identified 'exceptional leadership' as a key ambition for the long-term sustainability of the industry. This research investigates what it is like to be a veterinary surgeon in an in-practice leadership position, applying the qualitative methodology of interpretative phenomenological analysis. Through the researchers' interpretation of the seven participants' stories of their leadership experiences, the study advances understanding of the work environment, underlying motivations and the perceived responsibilities of veterinary leaders. Findings suggest, for many, a struggle in transition to leader positions, improving with time. The increase in pace of work is relayed by participants, with an ongoing, and unchallenged, work-life imbalance. The vets involved are highly motivated, driven by enjoyment of their jobs, a desire for self-determination and a need to make a difference. Relationships form the core of the perceived responsibilities, and yet are identified as the greatest day-to-day challenge of leadership. This study offers a valuable insight for veterinary surgeons, suggesting the industry could benefit from pausing and reflecting on behaviours. With a greater understanding of the complexity of leadership and followership, progress can be made to enact positive changes for the future. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

Electronic publishing in radiology: economics and the future.

PubMed

Chew, Felix S; Llewellyn, Kevin T; Olsen, Kathryn M

2004-11-01

Scholarly publishing is a large market involving thousands of peer-reviewed journals but a decreasing number of publishers. An economic model can be described in which authors give their work to publishers who then sell access to this work. Because each published article is a unique work with few if any substitutes, publishers have some degree of monopoly power and can price their products accordingly. The advent of desktop publishing using personal computers made it possible for individuals to publish material without publishers, an activity that gained momentum when the publishing medium shifted from paper to electronic, and from electronic publishing to the Internet. This activity destabilized the industry, and in the rush to gain market share by providing free content, unsustainable business models were created. Scholarly publishing is now dominated by a small number of multinational corporations that acquired many smaller publishing operations. As these companies have exercised their monopoly power, an open access movement has gained traction in which authors (or their institutions) initially pay for publication, but readers have free and open access to the published articles. This movement is in diametric opposition to the commercial publishing model, and it remains to be seen whether and how well the two can coexist in the future.

Work ability score and future work ability as predictors of register-based disability pension and long-term sickness absence: A three-year follow-up study.

PubMed

Kinnunen, Ulla; Nätti, Jouko

2018-05-01

We investigated two single items of the Work Ability Index - work ability score, and future work ability - as predictors of register-based disability pension and long-term sickness absence over a three-year follow-up. Survey responses of 11,131 Finnish employees were linked to pension and long-term (more than 10 days) sickness absence register data by Statistics Finland. Work ability score was divided into poor (0-5), moderate (6-7) and good/excellent (8-10) and future work ability into poor (1-2) and good (3) work ability at baseline. Cox proportional hazard regressions were used in the analysis of disability pension, and a negative binomial model in the analysis of long-term sickness absence. The results were adjusted for several background, work- and health-related covariates. Compared with those with good/excellent work ability scores, the hazard ratios of disability pension after adjusting for all covariates were 9.84 (95% CI 6.68-14.49) for poor and 2.25 (CI 95% 1.51-3.35) for moderate work ability score. For future work ability, the hazard ratio was 8.19 (95% CI 4.71-14.23) among those with poor future work ability. The incidence rate ratios of accumulated long-term sickness absence days were 3.08 (95% CI 2.19-4.32) and 1.59 (95% CI 1.32-1.92) for poor and moderate work ability scores, and 1.51 (95% CI 0.97-2.36) for poor future work ability. The single items of work ability score and future work ability predicted register-based disability pension equally well, but work ability score was a better predictor of register-based long-term sickness absence days than future work ability in a three-year follow-up. Both items seem to be of use especially when examining the risk of poor work ability for disability but also for long sick leave.

Therapist strategies early in therapy associated with good or poor outcomes among clients with low proactive agency.

Within a mixed methods program of research the present study aimed at expanding knowledge about interactions in the initial therapeutic collaboration by combining focus on client interpersonal style and therapist contribution. The study involves in-depth analyses of therapist-client interactions in the initial two sessions of good and poor outcome therapies. Based on interpersonal theory and previous research, the Inventory of Interpersonal Problems (IIP-64-C) was used to define poor outcome cases, that is, low proactive agency cases. To compare good and poor outcome cases matched on this interpersonal pattern, cases were drawn from two different samples; nine poor outcome cases from a large multi-site outpatient clinic study and nine good outcome cases from a process-outcome study of highly experienced therapists. Qualitative analysis of therapist behaviors resulted in 2 main categories, fostering client's proactive agentic involvement in change work and discouraging client's proactive agentic involvement in change work, 8 categories and 22 sub-categories. The findings revealed distinct and cohesive differences in therapist behaviors between the two outcome groups, and point to the particular therapist role of fostering client agency through engagement in a shared work on change when clients display strong unassertiveness and low readiness for change. Clinical or Methodological Significance Summary: The present analysis combines focus on client interpersonal style, therapist strategies/process and outcome. The categories generated from the present grounded theory analysis may serve as a foundation for identifying interactions that are associated with agentic involvement in future process research and practice, and hence we have formulated principles/strategies that were identified by the analysis.

Making sense of diversity in the workplace: organizational justice and language abstraction in employees' accounts of diversity-related incidents.

PubMed

Roberson, Quinetta M; Stevens, Cynthia Kay

2006-03-01

To discern patterns of employee sense-making about workplace diversity, the authors analyzed 751 natural language accounts of diversity incidents from 712 workers in one department of a large organization. Six generic incident types emerged: discrimination, representation, treatment by management, work relationships, respect between groups, and diversity climates. Consistent with hypotheses, incidents that respondents viewed as negative, accounts from women, and those involving members of respondents' in-groups were more likely to cite justice issues. Partially consistent with research on the linguistic intergroup bias, both negative and positive accounts involving out-group members and accounts from men were more likely to be expressed using abstract verb forms. The authors discuss future opportunities to integrate research on diversity, justice, and the linguistic category model.

Numerical scheme approximating solution and parameters in a beam equation

We present a mathematical model which describes vibration in a metallic beam about its equilibrium position. This model takes the form of a nonlinear second-order (in time) and fourth-order (in space) partial differential equation with boundary and initial conditions. A finite-element Galerkin approximation scheme is used to estimate model solution. Infinite-dimensional model parameters are then estimated numerically using an inverse method procedure which involves the minimization of a least-squares cost functional. Numerical results are presented and future work to be done is discussed.

Medical education for social justice: Paulo Freire revisited.

PubMed

DasGupta, Sayantani; Fornari, Alice; Geer, Kamini; Hahn, Louisa; Kumar, Vanita; Lee, Hyun Joon; Rubin, Susan; Gold, Marji

2006-01-01

Although social justice is an integral component of medical professionalism, there is little discussion in medical education about how to teach it to future physicians. Using adult learning theory and the work of Brazilian educator Paulo Freire, medical educators can teach a socially-conscious professionalism through educational content and teaching strategies. Such teaching can model non-hierarchical relationships to learners, which can translate to their clinical interactions with patients. Freirian teaching can additionally foster professionalism in both teachers and learners by ensuring that they are involved citizens in their local, national and international communities.

Steinthorsson, Erlendur

1997-01-01

A methodology for the simulation of turbine cooling flows is being developed. The methodology seeks to combine numerical techniques that optimize both accuracy and computational efficiency. Key components of the methodology include the use of multiblock grid systems for modeling complex geometries, and multigrid convergence acceleration for enhancing computational efficiency in highly resolved fluid flow simulations. The use of the methodology has been demonstrated in several turbo machinery flow and heat transfer studies. Ongoing and future work involves implementing additional turbulence models, improving computational efficiency, adding AMR.

Pulsation research during the IMS. [International Magnetospheric Study

Hughes, W. J.

1982-01-01

After describing the development status of the field of magnetic pulsations in 1975, before the initiation of the International Magnetospheric Study (IMS), attention is given to the IMS's novel observational results and an attempt is made to identify the most effective research methods employed. It is found that the most fruitful work involved small-scale collaboration between a few individuals or a few groups possessing complementary data sets. Consideration is restricted to research on the long period pulsations which can be broadly classified as field line resonances. Recommendations are made for future research efforts.

Limitations in both space and terrestial markets for solar cells are described. Based on knowledge of the state-of-the-art, six cell options are discussed; as a result of this discussion, the three most promising options (involving high, medium and low efficiency cells respectively) were selected and analyzed for their probable costs. The results showed that all three cell options gave promise of costs below $10 per watt in the near future. Before further cost reductions can be achieved, more R and D work is required; suggestions for suitable programs are given.

The paper deals with the study of structure, microstructure, composition and microhardness of a tube processed by electron-beam additive manufacturing using optical and scanning electron microscopy. The structure and macrodefects of a tube made of Grade2 titanium alloy is studied using the X-ray computed tomography. The principles of layer-by-layer assembly and boundaries after powder sintering are set out in this paper. It is found that the titanium alloy has two phases. Future work will involve methods to improve properties of created parts.

Understanding the mechanisms and optimizing ion transport in polymer membranes have been the subject of active research for more than three decades. We present an overview of the progress and challenges involved with the modeling and simulation aspects of the ion transport properties of polymer membranes. We are concerned mainly with atomistic and coarser level simulation studies and discuss some salient work in the context of pure binary and single ion conducting polymer electrolytes, polymer nanocomposites, block copolymers, and ionic liquid-based hybrid electrolytes. We conclude with an outlook highlighting future directions.

Lengel, Matthew; Kuhn, Catherine H; Worley, Marcia; Wehr, Allison M; McAuley, James W

To assess the impact of technician involvement on the completion of medication therapy management (MTM) services in a community pharmacy setting and to describe pharmacists' and technicians' perceptions of technician involvement in MTM-related tasks and their satisfaction with the technician's role in MTM. Prospective observational study. In the fall of 2015, pharmacists and selected technicians from 32 grocery store-based community pharmacies were trained to use technicians within MTM services. Completed MTM claims were evaluated at all pharmacies for 3 months before training and 3 months after training. An electronic survey, developed with the use of competencies taught in the training and relevant published literature, was distributed via e-mail to trained employees 3 months after training. The total number of completed MTM claims at the 32 pharmacy sites was higher during the posttraining time period (2687 claims) versus the pretraining period (1735 claims). Of the 182 trained participants, 112 (61.5%) completed the survey. Overall, perceived technician involvement was lower than expected. However, identifying MTM opportunities was the most commonly reported technician MTM task, with 62.5% of technicians and 47.2% of pharmacists reporting technician involvement. Nearly one-half of technicians (42.5%) and pharmacists (44.0%) agreed or strongly agreed they were satisfied with the technician's role in MTM services, and 40.0% of technicians agreed that they were more satisfied with their work in the pharmacy after involvement in MTM. Three months after initial training of technicians in MTM, participation of technicians was lower than expected. However, the technicians involved most often reported identifying MTM opportunities for pharmacists, which may be a focus for future technician trainings. In addition, technician involvement in MTM services may increase satisfaction with many aspects of work for actively involved technicians. Copyright © 2018 American Pharmacists Association®.

Health care is a complex sociotechnical system. Patient treatment is evolving and needs to incorporate the use of technology and new patient-centered treatment paradigms. Cognitive work analysis (CWA) is an effective framework for understanding complex systems, and work domain analysis (WDA) is useful for understanding complex ecologies. Although previous applications of CWA have described patient treatment, due to their scope of work patients were previously characterized as biomedical machines, rather than patient actors involved in their own care. An abstraction hierarchy that characterizes patients as beings with complex social values and priorities is needed. This can help better understand treatment in a modern approach to care. The purpose of this study was to perform a WDA to represent the treatment of patients with medical records. The methods to develop this model included the analysis of written texts and collaboration with subject matter experts. Our WDA represents the ecology through its functional purposes, abstract functions, generalized functions, physical functions, and physical forms. Compared with other work domain models, this model is able to articulate the nuanced balance between medical treatment, patient education, and limited health care resources. Concepts in the analysis were similar to the modeling choices of other WDAs but combined them in as a comprehensive, systematic, and contextual overview. The model is helpful to understand user competencies and needs. Future models could be developed to model the patient's domain and enable the exploration of the shared decision-making (SDM) paradigm. Our work domain model links treatment goals, decision-making constraints, and task workflows. This model can be used by system developers who would like to use ecological interface design (EID) to improve systems. Our hierarchy is the first in a future set that could explore new treatment paradigms. Future hierarchies could model the patient as a controller and could be useful for mobile app development. ©Justin D St-Maurice, Catherine M Burns.

2017-04-01

Science and Art are two disciplines that are usually treated as mutually exclusive entities, and yet which have much to offer each other in terms of process, experimentation and analysis. The field of SciArt (or ArtSci) is a relatively new one, in which scientists and artists work together to create information and demonstrations that are neither the science of art nor the art of science but are instead interdisciplinary investigations that utilise the unique strengths and overlapping commonalities of both fields. As well as the products and processes that are created via such collaboration, the introduction of artists and scientists to one another is an exceptionally valuable prospect which can have a significant impact on the working practices of both sets of collaborators. To further develop this field and these opportunities for collaboration, it is necessary to introduce scientists and artists to the potential of working together at an early point in their careers, ideally when they are still in tertiary education. Manchester Metropolitan University has been involved in several art and science programmes that involve science and art undergraduate and postgraduate students working together to create performances, experiments and demonstrations. This includes the UK's first dedicated SciArt course, residential field trips, and exhibiting at an internationally- renowned gallery. Here we present the outcomes of this work, discussing the development of these schemes and presenting future opportunities for early career scientists and artists to collaborate further.

The NASA Science Mission Directorate (SMD) Education and Public Outreach (EPO) Forums have established a Higher Education Working Group (HEWG), which has explored and surveyed the higher education landscape with regard to different subjects, such as community colleges and diversity. The HEWG is composed of representatives from each of the SMD EPO Forums, along with 'external' members who have rotated in and out, and the co-authors here constitute the present membership, chaired by Nicholas Gross. Most recently, the HEWG has worked to identify the key characteristics of higher education STEM programs that reach diverse populations. While increasing the involvement of students from diverse backgrounds in SMD EPO is a core goal for our community, engaging these students meaningfully requires a dedicated strategy using proven techniques. In reality, while most educational programs have this goal, undertaking it meaningfully is more challenging. For higher education, diversity is a long-standing issue, and the working group could have taken many different paths to explore this important topic. The HEWG has undertaken a review of programs that involve engaging undergraduates from diverse backgrounds in SMD-related research internships or hands-on STEM experiments. This information will be synthesized and documented so that future education efforts can incorporate the most valuable components. Meanwhile, the working group is exploring ways that NASA SMD can be more helpful to higher education faculty and students, and community input is solicited as part of this presentation.

A new framing approach in guideline development to manage different sources of knowledge.

Contemporary guideline methodology struggles to consider context and information from different sources of knowledge besides quantitative research. Return to work programmes involve multiple components and stakeholders. If the guideline is to be relevant and practical for a complex intervention such as return to work, it is essential to use broad sources of knowledge. This paper reports on a new method in guideline development to manage different sources of knowledge. The method used framing for the return-to-work guidance within the Clinical Practice Guidelines for the Management of Rotator Cuff Syndrome in the Workplace. The development involved was a multi-disciplinary working party of experts including consumers. The researchers considered a broad range of research, expert (practice and experience) knowledge, the individual's and workplace contexts, and used framing with the International Classification of Functioning, Disability and Health. Following a systematic database search on four clinical questions, there were seven stages of knowledge management to extract, unpack, map and pack information to the ICF domains framework. Companion graded recommendations were developed. The results include practical examples, user and consumer guides, flow charts and six graded or consensus recommendations on best practice for return to work intervention. Our findings suggest using framing in guideline methodology with internationally accepted frames such as the ICF is a reliable and transparent framework to manage different sources of knowledge. Future research might examine other examples and methods for managing complexity and using different sources of knowledge in guideline development. © 2016 John Wiley & Sons, Ltd.

2009-10-01

Detecting adverse events (AE) is part of managing hospitalised patients' safety. Suitable AE monitoring is affected by many factors regarding any particular institution and its workers. This article was aimed at describing the difficulties emerging from identifying and evaluating events and suggested interventions from the workers' viewpoint. Qualitative research. A focus group was formed with key informants from previous research entitled 'The incidence and avoidability of adverse events in three institutions in Colombia, 2006.' A conceptual framework was constructed based on publications pertaining to AEs and health-providing institutions; summaries were made by topic regarding the content of the focus group's work by systematising, categorising and readjusting the data. The triangulation method was used for guar-anteeing its credibility, transferability, reliability and that it could be confirmed. It is commonly thought that monitoring AE only consists of taking inventories related to negative work consequences into account; this opinion has been determined by prior organisational culture. Strategies used for increasing AE reporting were: intrapersonal work, raising awareness that nobody is exempt from being involved in an adverse event and encouraging administrative support for resolving deficiencies. The prospective monitoring method becomes hampered when applying it to services involving a large volume of information. A tendency was observed for specialist committees to underestimate an event's association. Heath workers, support personnel and management must have mutual confidence and adopt team-work so that future AE may be prevented.

Work-Home Interference, Perceived Total Workload, and the Risk of Future Sickness Absence Due to Stress-Related Mental Diagnoses Among Women and Men: a Prospective Twin Study.

2018-02-01

Work-home interference has been proposed as an important explanation for sickness absence (SA). Previous studies show mixed results, have not accounted for familial factors (genetics and shared everyday environment), or investigated diagnosis specific SA. The aim was to study whether work-home interference and perceived total workload predict SA due to stress-related mental diagnoses, or SA due to other mental diagnoses, among women and men, when adjusting for various confounders and familial factors. This study included 11,916 twins, 19-47 years (49% women). Data on work-to-home and home-to-work conflicts, perceived total workload, and relevant confounders were derived from a 2005 survey, and national register data on SA spells until 2013 were obtained. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Discordant twin pair design was applied to adjust for familial factors. Each one unit increase in work-to-home and home-to-work conflicts, and perceived total workload was associated with higher odds for SA due to stress-related mental diagnoses and to SA due to other mental diagnoses among women, when adjusting for sociodemographic factors (ORs 1.15-1.31). Including health or familial factors, no associations remained. For men, each one unit increase in work-to-home conflicts was associated with higher odds for SA due to stress-related diagnoses (ORs 1.23-1.35), independently of confounders. Work-to-home conflict was independently associated with future SA due to stress-related diagnoses among men only. Health- and work-related factors seem to be important confounders when researching work-home interference, perceived total workload, and SA. Not including such confounders involves risking drawing incorrect conclusions. Further studies are needed to confirm sex differences and whether genetic factors are important for the associations studied.

Identification of Threshold Concepts for Biochemistry

Green, David; Lewis, Jennifer E.; Lin, Sara; Minderhout, Vicky

2014-01-01

Threshold concepts (TCs) are concepts that, when mastered, represent a transformed understanding of a discipline without which the learner cannot progress. We have undertaken a process involving more than 75 faculty members and 50 undergraduate students to identify a working list of TCs for biochemistry. The process of identifying TCs for biochemistry was modeled on extensive work related to TCs across a range of disciplines and included faculty workshops and student interviews. Using an iterative process, we prioritized five concepts on which to focus future development of instructional materials. Broadly defined, the concepts are steady state, biochemical pathway dynamics and regulation, the physical basis of interactions, thermodynamics of macromolecular structure formation, and free energy. The working list presented here is not intended to be exhaustive, but rather is meant to identify a subset of TCs for biochemistry for which instructional and assessment tools for undergraduate biochemistry will be developed.

In this study, sustained, selective, divided, and switching attention, and reloading of working memory were investigated in schizophrenia by using a newly developed Visual Attention Battery (VAB). Twenty-four outpatients with schizophrenia and 24 control participants were studied using the VAB. Performance on VAB components was correlated with performance of standard tests. Patients with schizophrenia were significantly impaired on VAB tasks that required switching of attention and reloading of working memory but had normal performance on tasks involving sustained attention or attention to multiple stimulus features. Switching attention and reloading of working memory were highly correlated with Trails (B-A) score for patients. The decline in performance on the switching-attention task in patients with schizophrenia met criteria for a differential deficit in switching attention. Future research should examine the neurophysiological basis of the switching deficit and its sensitivity and specificity to schizophrenia.

2017-01-01

Background Work-related musculoskeletal disorders (WMSD) among construction workers remain high. Participatory ergonomics (PE) interventions that engage workers and employers in reducing work injury risks have shown mixed results. Methods Eight-six workers from seven contractors participated in a PE program. A logic model guided the process evaluation and summative evaluation of short term and intermediate impacts and long term outcomes from surveys and field records. Results Process measures showed good delivery of training, high worker engagement, and low contractor participation. Workers’ knowledge improved and workers reported changes to work practices and tools used; contractor provision of appropriate equipment was low (33%). No changes were seen in symptoms or reported physical effort. Conclusions The PE program produced many worker-identified ergonomic solutions, but lacked needed support from contractors. Future interventions should engage higher levels of the construction organizational system to improve contractor involvement for reducing WMSD. PMID:27094450

Applying Organizational Learning Research to Accountable Care Organizations.

Nembhard, Ingrid M; Tucker, Anita L

2016-12-01

To accomplish the goal of improving quality of care while simultaneously reducing cost, Accountable Care Organizations (ACOs) need to find new and better ways of providing health care to populations of patients. This requires implementing best practices and improving collaboration across the multiple entities involved in care delivery, including patients. In this article, we discuss seven lessons from the organizational learning literature that can help ACOs overcome the inherent challenges of learning how to work together in radically new ways. The lessons involve setting expectations, creating a supportive culture, and structuring the improvement efforts. For example, with regard to setting expectations, framing the changes as learning experiences rather than as implementation projects encourages the teams to utilize helpful activities, such as dry runs and pilot tests. It is also important to create an organizational culture where employees feel safe pointing out improvement opportunities and experimenting with new ways of working. With regard to structure, stable, cross-functional teams provide a powerful building block for effective improvement efforts. The article concludes by outlining opportunities for future research on organizational learning in ACOs. © The Author(s) 2016.

Seeking a balance between the statistical and scientific elements in psychometrics.

Wilson, Mark

2013-04-01

In this paper, I will review some aspects of psychometric projects that I have been involved in, emphasizing the nature of the work of the psychometricians involved, especially the balance between the statistical and scientific elements of that work. The intent is to seek to understand where psychometrics, as a discipline, has been and where it might be headed, in part at least, by considering one particular journey (my own). In contemplating this, I also look to psychometrics journals to see how psychometricians represent themselves to themselves, and in a complementary way, look to substantive journals to see how psychometrics is represented there (or perhaps, not represented, as the case may be). I present a series of questions in order to consider the issue of what are the appropriate foci of the psychometric discipline. As an example, I present one recent project at the end, where the roles of the psychometricians and the substantive researchers have had to become intertwined in order to make satisfactory progress. In the conclusion I discuss the consequences of such a view for the future of psychometrics.

Family science: What is it?

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

Whitlow, B.

Family science is an informal science education program designed to teach science skills by having children and parents learn and enjoy science together. Aimed at addressing the underrepresentation of women and ethnic and racial minorities in science-based careers, FAMILY SCIENCE involves parents and children in kindergarten through eighth grade in science activities that demonstrate the role science plays in their daily life and future. Family involvement is the key to the program`s effectiveness. Family classes are usually offered in a series of one- to two-hour class meetings for parents and their children after school, evenings, and weekends. During classes, parentsmore » and children work in pairs and small groups to solve problems, work cooperatively, and talk science. The activities provide experiences for the entire family that build skills, confidence, and interest in science. In addition, guest speakers and career activities illustrate for parents in the workforce the significance of math and science in their own jobs, and for kids, it highlights the diversity of jobs and the relevance of math and science.« less

Shaping the Future of Prevention in Social Work: An Analysis of the Professional Literature from 2000 through 2010

2016-01-01

In light of the Patient Protection and Affordable Care Act’s goals of better patient care, cost control, and improved population outcomes, prevention is emerging as an important component of health reform. As a result, broad societal interest in prevention is growing, together with widespread interest in public health. The profession, with its extensive involvement in the health system and deep roots in public health, needs to know more about its relationship to prevention. This study builds upon the Social Work Interest in Prevention Study–which evaluated the extent, types, and levels of prevention content in nine social work journals over a six year time period from 2000–2005. The goal of the expanded study, the Social Work Interest in Prevention Study-Expansion (SWIPS-E), was to assess whether interest in prevention had increased over the full decade, which included the time period in which health care reform was enacted.

Thermal stress, human performance, and physical employment standards.

PubMed

Cheung, Stephen S; Lee, Jason K W; Oksa, Juha

2016-06-01

Many physically demanding occupations in both developed and developing economies involve exposure to extreme thermal environments that can affect work capacity and ultimately health. Thermal extremes may be present in either an outdoor or an indoor work environment, and can be due to a combination of the natural or artificial ambient environment, the rate of metabolic heat generation from physical work, processes specific to the workplace (e.g., steel manufacturing), or through the requirement for protective clothing impairing heat dissipation. Together, thermal exposure can elicit acute impairment of work capacity and also chronic effects on health, greatly contributing to worker health risk and reduced productivity. Surprisingly, in most occupations even in developed economies, there are rarely any standards regarding enforced heat or cold safety for workers. Furthermore, specific physical employment standards or accommodations for thermal stressors are rare, with workers commonly tested under near-perfect conditions. This review surveys the major occupational impact of thermal extremes and existing employment standards, proposing guidelines for improvement and areas for future research.

This paper presents the activities and publications of Organisation for Economic Co-operation and Developments (OECD's) Working Group on Harmonisation of Regulatory Oversight in Biotechnology and the Task Force for the Safety of Novel Foods and Feeds. The main outputs of the work are the Series of "consensus documents" of the respective groups. These documents compile information which is intended to be used by those involved in the business of risk/safety assessment. These documents are one means of ensuring the transportability of data amongst authorities. An increasing trend in both the Working Group and Task Force is to consider crop species which are relevant to tropical regions and therefore to countries that are not necessarily members of the OECD. For example, the Working Group has recently published a consensus document on bananas and plantains while the Task Force has published a document on cassava. This trend towards crops of greater interest in the tropics is likely to continue into the future.

Because of their involvement with the Affordable Care exchanges, the national insurance companies have reported significant financial losses. As a result, there will soon be significant payer pressure to reduce medical expenses. To succeed in future negotiations with the payers, medical practices must understand the needs of the payers and then play to those needs. The author is a former managed care executive with more than 25 years of experience managing provider networks and implementing payer strategies for some of the largest payers in the United States. In this article, he outlines important things medical practices should be doing to prepare for the new world of value-based contracting. Medical practices that embrace this change and work hard to evolve with the future are the ones that are going to survive and succeed.

1984-01-01

The human role in space was studied. The role and the degree of direct involvement of humans that will be required in future space missions, was investigated. Valid criteria for allocating functional activities between humans and machines were established. The technology requirements, ecnomics, and benefits of the human presence in space were examined. Factors which affect crew productivity include: internal architecture; crew support; crew activities; LVA systems; IVA/EVA interfaces; and remote systems management. The accomplished work is reported and the data and analyses from which the study results are derived are included. The results provide information and guidelines to enable NASA program managers and decision makers to establish, early in the design process, the most cost effective design approach for future space programs, through the optimal application of unique human skills and capabilities in space.

KEO, the Archeological Bird of the Future, is a project linking art and space, which seeks to involve people of all ages and cultures in a collective work of art : while exciting our imagination, it invites us to reflect upon the use we make of the exceptional capabilities our species is endowed with. A time-capsule to be launched in 2003, KEO is meant to come back passively to its native soil, where it will land safe and sound, in some 50 000 years. It will then act as our messenger to our distant descendants, delivering to them, intact, our common offering : all the messages that each of us, men, women and children of today's Earth wish to pass on to the Future. From its very start on Internet KEO was elected by an overwhelming world-wide majority of teachers as an oustanding pedagogic tool allowing interdisciplinary classes which use to arouse the greatest interest amongst students whatever theri level. .A KEO pedagogic kit was worked out as a support to enable the teachers to make the most of KEO by giving lectures combining art, sciences spatial technologies, human development. This obviously awakens student's citizenship awareness. The paper will especially deal with the pedagogic experiences conducted in French in the Reunion Island, Paris and in Quebec (Canada).This presentation will insist on the public outreach activities providing evidence for the benefits such an project as KEO can offer to society.

Embracing a diversified future for US primary care.

PubMed

Hoff, Timothy

2013-01-01

Although less focused upon given the current emphasis on the patient-centered medical home innovation, the future for US primary care is arguably one that will be characterized by diversity in service delivery structures and personnel. The drivers of this diversity include increased patient demand requiring a larger number of primary care access points; the need for lower-cost delivery structures that can flourish in a low-margin business model; greater interest in primary care delivery by retailers and hospitals that see their involvement as a means to enhance their core business goals; the increased desire by non-physician providers to gain work independence; and a growing cadre of younger PCPs whose career and job preferences leave them open to working in a variety of different settings and structures. A key issue to ask of a more diversified primary care system is whether or not it will be characterized by competition or cooperation. While a competitive system would not be unexpected given historical and current trends, such a system would likely stunt the prospects for a full revitalization of US primary care. However, there is reason to believe that a cooperative system is possible and would be advantageous, given the mutual dependencies that already exist among primary care stakeholders, and additional steps that could be taken to enhance such dependencies even more into the future.

To design and administer an attitude rating scale, exploring colorectal cancer patients' views of involvement in decision making. To examine the impact of socio-demographic and/or treatment-related factors on decision making. To conduct principal components analysis to determine if the scale could be simplified into a number of factors for future clinical utility. An attitude rating scale was constructed based on previous qualitative work and administered to colorectal cancer patients using a cross-sectional survey approach. 375 questionnaires were returned (81.7% response). For patients it was important to be informed and involved in the decision-making process. Information was not always used to make decisions as patients placed their trust in medical expertise. Women had more positive opinions on decision making and were more likely to want to make decisions. Written information was understood to a greater degree than verbal information. The scale could be simplified to a number of factors, indicating clinical utility. Few studies have explored the attitudes of colorectal cancer patients towards involvement in decision making. This study presents new insights into how patients view the concept of participation; important when considering current policy imperatives in the UK of involving service users in all aspects of care and treatment.

To describe the realities of conducting a cross-jurisdictional data linkage project involving state and Australian Government-based data collections to inform future national data linkage programs of work. We outline the processes involved in conducting a Proof of Concept data linkage project including the implementation of national data integration principles, data custodian and ethical approval requirements, and establishment of data flows. The approval process involved nine approval and regulatory bodies and took more than two years. Data will be linked across 12 datasets involving three data linkage centres. A framework was established to allow data to flow between these centres while maintaining the separation principle that serves to protect the privacy of the individual. This will be the first project to link child immunisation records from an Australian Government dataset to other administrative health datasets for a population cohort covering 2 million births in two Australian states. Although the project experienced some delays, positive outcomes were realised, primarily the development of strong collaborations across key stakeholder groups including community engagement. We have identified several recommendations and enhancements to this now established framework to further streamline the process for data linkage studies involving Australian Government data. © 2015 Public Health Association of Australia.

The work performed under this grant has led to the development of a detection system that will be used to measure reaction rates for proton or neutron capture reactions at stellar energies on radioactive ions far from stability. The reaction rates are needed to better understand the physics of nucleosynthesis in explosive stellar processes such as supernovae and x-ray burst events. The radioactive ions will be produced at the Radioactive Ion Beam Facility (RIBF) at RIKEN near Tokyo, Japan. During the course of this work, the group involved in this project has expanded by several institutions in Europe and Japanmore » and now involves collaborators from the U.S., Japan, Hungary, Romania, Germany, Spain, Italy, China, and South Korea. As part of the project, a novel design based on large-area silicon detectors has been built and tested. The work has involved mechanical construction of a special purpose vacuum chamber, with a precision mounting system for the silicon detectors, development of a new ASICs readout system that has applications with a wide variety of silicon detector systems, and the development of a data acquisition system that is integrated into the computer system being used at RIBF. The parts noted above that are needed to carry out the research program are completed and ready for installation. Several approved experiments that will use this system will be carried out in the near future. The experimental work has been delayed due to a large increase in the cost and availability of electrical power for RIBF that occurred following the massive earthquake and tsunami that hit Japan in the spring of 2011. Another component of the research carried out with this grant involved developing the theoretical tools that are required to extract the information from the experiments that is needed to determine the stellar reaction rates.

The reliability of model projections of greenhouse gas (GHG)-induced future climate change is often assessed based on models’ ability to simulate the current climate, but there has been little evidence that connects the two. In fact, this practice has been questioned because the GHG-induced future climate change may involve additional physical processes that are not important for the current climate.

The results suggest that many physical processes may work similarly in producing the year-to-year climate variations in the current climate and the GHG-induced long-term changes in the 21 st century in models and in the real world.

Panning artifacts in digital pathology images

Avanaki, Ali R. N.; Lanciault, Christian; Espig, Kathryn S.; Xthona, Albert; Kimpe, Tom R. L.

2017-03-01

In making a pathologic diagnosis, a pathologist uses cognitive processes: perception, attention, memory, and search (Pena and Andrade-Filho, 2009). Typically, this involves focus while panning from one region of a slide to another, using either a microscope in a traditional workflow or software program and display in a digital pathology workflow (DICOM Standard Committee, 2010). We theorize that during panning operation, the pathologist receives information important to diagnosis efficiency and/or correctness. As compared to an optical microscope, panning in a digital pathology image involves some visual artifacts due to the following: (i) the frame rate is finite; (ii) time varying visual signals are reconstructed using imperfect zero-order hold. Specifically, after pixel's digital drive is changed, it takes time for a pixel to emit the expected amount of light. Previous work suggests that 49% of navigation is conducted in low-power/overview with digital pathology (Molin et al., 2015), but the influence of display factors has not been measured. We conducted a reader study to establish a relationship between display frame rate, panel response time, and threshold panning speed (above which the artifacts become noticeable). Our results suggest visual tasks that involve tissue structure are more impacted by the simulated panning artifacts than those that only involve color (e.g., staining intensity estimation), and that the panning artifacts versus normalized panning speed has a peak behavior which is surprising and may change for a diagnostic task. This is work in progress and our final findings should be considered in designing future digital pathology systems.

Dendrimer-based nanoparticles for cancer therapy.

Baker, James R

2009-01-01

Recent work has suggested that nanoparticles in the form of dendrimers may be a keystone in the future of therapeutics. The field of oncology could soon be revolutionized by novel strategies for diagnosis and therapy employing dendrimer-based nanotherapeutics. Several aspects of cancer therapy would be involved. Diagnosis using imaging techniques such as MRI will be improved by the incorporation of dendrimers as advanced contrast agents. This might involve novel contrast agents targeted specifically to cancer cells. Dendrimers can also be being applied to a variety of cancer therapies to improve their safety and efficacy. A strategy, somewhat akin to the "Trojan horse," involves targeting anti-metabolite drugs via vitamins or hormones that tumors need for growth. Further applications of dendrimers in photodynamic therapy, boron neutron capture therapy, and gene therapy for cancer are being examined. This presentation will cover the fundamentals of research utilizing dendrimers for cancer diagnosis and therapy. An evaluation of this new technologies will detail what advantage dendrimer based therapeutics might have over conventional cancer drugs.

This paper presents the findings from an evaluation of a creative musical project led by Scottish Opera. The project included people with dementia and their carers in the development, writing, design and performance of a musical production about their experiences of love. The project involved professional singers, artists and choreographers from the opera company. Activities involved practice sessions and performances. People with dementia and their carers reflected on positive outcomes from the project including improved confidence; being part of a group; improved physical strength and people seeing them in a new way. Within the evaluation framework they also reported on how the project had been run and gave ideas for future development. Key elements in the success of this project were the involvement of professionals, the kudos of working with a national organisation and the performances that, while daunting, provided unique and rewarding experiences. © The Author(s) 2013.

Climate change impacts on groundwater recharge- uncertainty, shortcomings, and the way forward?

NASA Astrophysics Data System (ADS)

Holman, I. P.

2006-06-01

An integrated approach to assessing the regional impacts of climate and socio-economic change on groundwater recharge is described from East Anglia, UK. Many factors affect future groundwater recharge including changed precipitation and temperature regimes, coastal flooding, urbanization, woodland establishment, and changes in cropping and rotations. Important sources of uncertainty and shortcomings in recharge estimation are discussed in the light of the results. The uncertainty in, and importance of, socio-economic scenarios in exploring the consequences of unknown future changes are highlighted. Changes to soil properties are occurring over a range of time scales, such that the soils of the future may not have the same infiltration properties as existing soils. The potential implications involved in assuming unchanging soil properties are described. To focus on the direct impacts of climate change is to neglect the potentially important role of policy, societal values and economic processes in shaping the landscape above aquifers. If the likely consequences of future changes of groundwater recharge, resulting from both climate and socio-economic change, are to be assessed, hydrogeologists must increasingly work with researchers from other disciplines, such as socio-economists, agricultural modellers and soil scientists.

New technology is continuously introduced in health care. The aim of this study was (1) to collect the opinions and experiences of radiographers, nuclear medicine technologists and radiation therapists regarding the technology they use in their profession and (2) to acquire their views regarding the role of technology in their future practice. Participants were recruited from five departments in five hospitals in The Netherlands. All radiographers, nuclear medicine therapists and radiation therapists who were working in these departments were invited to participate (n = 252). The following topics were discussed: technology in daily work, training in using technology and the role of technology in future practice. The recorded interviews were transcribed verbatim and analysed using open and axial coding. A total of 52 participants (57.7% radiographer) were included, 19 men and 33 women (age range: 20-63). Four major themes emerged: (1) technology as an indispensable factor, (2) engagement, support and training in using technology, (3) transitions in work and (4) the radiographer of the future. All participants not only value technological developments to perform their occupations, but also aspects such as documentation and physical support. When asked about the future of their profession, contradictory answers were provided; while some expect less autonomy, others belief they will get more autonomy in their work. Technology plays a major role in all three occupations. All participants believe that technology should be in the best interests of patients. Being involved in the implementation of new technology is of utmost importance; courses and training, facilitated by the managers of the departments, should play a major role. Only when a constant dialogue exists between health care professionals and their managers, in which they discuss their experiences, needs and expectations, technology can be implemented in a safe and effective manner. This, in turn, might positively influence quality of care. © 2017 The Authors.

Objectives: to describe the views of healthcare workers on the facilitators of communication with people with dementia in a care setting. Design: thematic analysis of semi-structured interviews. Setting: all participants were interviewed in their place of work. Participants: sixteen healthcare workers whose daily work involves interacting with people with dementia. Results: four overarching categories of themes were identified from the interviews that impact on communication: the attributes of a care worker, communication strategies used, organisational factors and the physical characteristics of the care environment. Conclusion: many strategies used by healthcare workers to facilitate communication have not yet been studied in the research literature. Participants' views on training should be incorporated into future dementia training programmes. PMID:26764403

Explaining the Relationship between Employment and Juvenile Delinquency*

Most criminological theories predict an inverse relationship between employment and crime, but teenagers' involvement in paid work during the school year is positively correlated with delinquency and substance use. Whether the work-delinquency association is causal or spurious has long been debated. This study estimates the effect of paid work on juvenile delinquency using longitudinal data from the national Monitoring the Future project. We address issues of spuriousness by using a two-level hierarchical model to estimate the relationships of within-individual changes in juvenile delinquency and substance use to those in paid work and other explanatory variables. We also disentangle effects of actual employment from preferences for employment to provide insight about the likely role of time-varying selection factors tied to employment, delinquency, school engagement, and leisure activities. Whereas causal effects of employment would produce differences based on whether and how many hours respondents worked, we found significantly higher rates of crime and substance use among non-employed youth who preferred intensive versus moderate work. Our findings suggest the relationship between high-intensity work and delinquency results from preexisting factors that lead youth to desire varying levels of employment. PMID:21442045

Suicide rates are elevated in the veterinary profession in several countries, yet little is known about possible contributory and preventive factors. To obtain information from veterinarians with a history of suicidal ideation or behavior about the factors associated with suicidality in their profession. We conducted a mixed-methods interview study with 21 UK veterinarians who had attempted suicide or reported recent suicidal ideation. Interview topics included work and nonwork contributory factors, coping mechanisms, and preventive factors. Self-poisoning was the most common method used or considered by participants. Common contributory factors were workplace relationships, career concerns, patient issues, number of hours and volume of work, and responsibility, although two-thirds of participants reported co-occurring difficult life events. Around half had received a psychiatric diagnosis following their suicidal behavior. Several possible preventive measures were suggested by participants. Several work- and non-work-related contributory factors to suicidality in the veterinary profession were identified. Future preventive measures may involve better promotion of support services, formal support for recent graduates, and improving employers' attitudes toward work-life balance.

Lasers in space

A variety of laser applications in space, past, present, future and far future are reviewed together with the contributions of some of the scientists and engineers involved, especially those that happen to have South African connections. Historically, two of the earliest laser applications in space, were atmospheric LIDAR and lunar ranging. These applications involved atmospheric physicists, several astronauts and many of the staff recruited into the Soviet and North American lunar exploration programmes. There is a strong interest in South Africa in both LIDAR and lunar ranging. Shortly after the birth of the laser (and even just prior) theoretical work on photonic propulsion and space propulsion by laser ablation was initiated by Georgii Marx, Arthur Kantrowitz and Eugen Saenger. Present or near future experimental programs are developing in the following fields: laser ablation propulsion, possibly coupled with rail gun or gas gun propulsion; interplanetary laser transmission; laser altimetry; gravity wave detection by space based Michelson interferometry; the de-orbiting of space debris by high power lasers; atom laser interferometry in space. Far future applications of laser-photonic space-propulsion were also pioneered by Carl Sagan and Robert Forward. They envisaged means of putting Saenger's ideas into practice. Forward also invented a laser based method for manufacturing solid antimatter or SANTIM, well before the ongoing experiments at CERN with anti-hydrogen production and laser-trapping. SANTIM would be an ideal propellant for interstellar missions if it could be manufactured in sufficient quantities. It would be equally useful as a power source for the transmission of information over light year distances. We briefly mention military lasers. Last but not least, we address naturally occurring lasers in space and pose the question: "did the Big Bang lase?"

Membrane fusion is one of the most fundamental physiological processes in eukaryotes for triggering the fusion of lipid and content, as well as the neurotransmission. However, the architecture features of neurotransmitter release machinery and interdependent mechanism of synaptic membrane fusion have not been extensively studied. This review article expounds the neuronal membrane fusion processes, discusses the fundamental steps in all fusion reactions (membrane aggregation, membrane association, lipid rearrangement and lipid and content mixing) and the probable mechanism coupling to the delivery of neurotransmitters. Subsequently, this work summarizes the research on the fusion process in synaptic transmission, using electron microscopy (EM) and molecular simulation approaches. Finally, we propose the future outlook for more exciting applications of membrane fusion involved in synaptic transmission, with the aid of stochastic optical reconstruction microscopy (STORM), cryo-EM (cryo-EM), and molecular simulations.

Relationships between occupational functioning and stress among radio journalists--Assessment by means of the Psychosocial Risk Scale.

Job characteristics and the consequences of everyday stress among radio journalists who are not exposed to traumatic events have not been studied sufficiently before. We aimed at determining the most common job characteristics and their stressfulness; relationships between stress exposure, health and occupational functioning; differences between radio journalists and other journalists, and also the psychosocial risk for health and functioning in this group. The studied group involved 208 journalists, 134 of whom worked in radio stations. The respondents filled in the Psychosocial Risks Scale (PRS) developed by the Department of Health and Work Psychology of the Nofer Institute of Occupational Medicine, Łódź, Poland. Requirement of mental effort and readiness to response quickly for most of the time as well as limited possibilities for promotion were the most frequent journalists' complaints. We confirmed that higher levels of stress resulted in worse functioning--the radio journalists who experienced lower stress assessed their health status and ability to work better, were more satisfied with particular aspects of their work, and were more involved in their work. They also presented a significantly lower turnover intention. Moreover, the radio journalists were more involved in their work than other journalists, but experienced lower satisfaction, took more sick leaves and had more days of absence. Well-known relationships between stress level, satisfaction and occupational functioning were confirmed. The most important conclusion refers to the fact that psychosocial risks and stress analysis should be based on the understanding of specificity of each occupation or even position. It is so, because the same job characteristic may pose a challenge for one person, while for another--it can result in extreme discomfort and anxiety--such an attitude broadens understanding of the phenomenon. We also confirmed that the PRS is a well-designed method, appropriate to investigate an individual perception of job environment and its stressfulness. Future research on causal relationships between the variables is recommended. This work is available in Open Access model and licensed under a CC BY-NC 3.0 PL license.

Involvement and structure: A qualitative study of organizational change and sickness absence among women in the public sector in Sweden

PubMed Central

2011-01-01

Background Organizational changes in modern corporate life have become increasingly common and there are indications that they often fail to achieve their ends. An earlier study of 24,036 employees showed that those who had repeatedly been exposed to large increases in staffing during 1991-1996 had an excess risk of both long-term sickness absence and hospital admission during 1997-1999, while moderate expansion appeared to be protective. The former was most salient among female public sector employees. We used qualitative interviews to explore work environment factors underlying the impact of organizational changes (moderate and large expansions in staffing) on sickness absence from an employee perspective. Method We interviewed 21 strategically selected women from the earlier study using semi-structured telephone interviews focusing on working conditions during the organizational changes. We identified 22 themes which could explain the association between organizational changes and sickness absence. We then used Qualitative Comparative Analysis (QCA) to reduce the number of themes and discover patterns of possible causation. Results The themes that most readily explained the outcomes were Well Planned Process of Change (a clear structure for involvement of the employees in the changes), Agent of Change (an active role in the implementation of the changes), Unregulated Work (a lack of clear limits and guidelines regarding work tasks from the management and among the employees), and Humiliating Position (feelings of low status or of not being wanted at the workplace), which had been salient throughout the analytic process, in combination with Multiple Contexts (working in several teams in parallel) and Already Ill (having already had a debilitating illness at the beginning of 1991), which may indicate degree of individual exposure and vulnerability. Well Planned Process of Change, Agent of Change and Multiple Contexts are themes that were associated with low sickness absence. Unregulated Work, Humiliating Position and Already Ill were associated with high sickness absence. Conclusions These findings suggest that promising areas for future research and improvement in change management could be the structured involvement of the employees in the planning of organizational changes, and the development of methods to avoid highly unregulated working conditions.

Future orientation can be defined as an individual’s thoughts, beliefs, plans, and hopes for the future. Earlier research has shown adolescents’ future orientation to predict outcomes later in life, which makes it relevant to analyze differences in future orientation among youth. The aim of the present study was to analyze if bullying victimization was associated with an increased likelihood of reporting a pessimistic future orientation among school youth. To be able to distinguish between victims and bully-victims (i.e., students who are both bullies and victims), we also took perpetration into account. The data were derived from the Stockholm School Survey performed in 2016 among ninth grade students (ages 15–16 years) (n = 5144). Future orientation and involvement in school bullying and in cyberbullying were based on self-reports. The statistical method used was binary logistic regression. The results demonstrated that victims and bully-victims of school bullying and of cyberbullying were more likely to report a pessimistic future orientation compared with students not involved in bullying. These associations were shown also when involvement in school bullying and cyberbullying were mutually adjusted. The findings underline the importance of anti-bullying measures that target both school bullying and cyberbullying. PMID:29584631

The aim of the present study was to analyze if bullying victimization was associated with an increased likelihood of reporting a pessimistic future orientation among school youth. To be able to distinguish between victims and bully-victims (i.e., students who are both bullies and victims), we also took perpetration into account. The data were derived from the Stockholm School Survey performed in 2016 among ninth grade students (ages 15-16 years) ( n = 5144). Future orientation and involvement in school bullying and in cyberbullying were based on self-reports. The statistical method used was binary logistic regression. The results demonstrated that victims and bully-victims of school bullying and of cyberbullying were more likely to report a pessimistic future orientation compared with students not involved in bullying. These associations were shown also when involvement in school bullying and cyberbullying were mutually adjusted. The findings underline the importance of anti-bullying measures that target both school bullying and cyberbullying.

The Microgravity Science Glovebox (MSG) is a double rack facility aboard the International Space Station (ISS), which accommodates science and technology investigations in a "workbench' type environment. The MSG has been operating on the ISS since July 2002 and is currently located in the US Laboratory Module. In fact, the MSG has been used for over 10,000 hours of scientific payload operations and plans to continue for the life of ISS. The facility has an enclosed working volume that is held at a negative pressure with respect to the crew living area. This allows the facility to provide two levels of containment for small parts, particulates, fluids, and gases. This containment approach protects the crew from possible hazardous operations that take place inside the MSG work volume and allows researchers a controlled pristine environment for their needs. Research investigations operating inside the MSG are provided a large 255 liter enclosed work space, 1000 watts of dc power via a versatile supply interface (120, 28, + 12, and 5 Vdc), 1000 watts of cooling capability, video and data recording and real time downlink, ground commanding capabilities, access to ISS Vacuum Exhaust and Vacuum Resource Systems, and gaseous nitrogen supply. These capabilities make the MSG one of the most utilized facilities on ISS. MSG investigations have involved research in cryogenic fluid management, fluid physics, spacecraft fire safety, materials science, combustion, and plant growth technologies. Modifications to the MSG facility are currently under way to expand the capabilities and provide for investigations involving Life Science and Biological research. In addition, the MSG video system is being replaced with a state-of-the-art, digital video system with high definition/high speed capabilities, and with near real-time downlink capabilities. This paper will provide an overview of the MSG facility, a synopsis of the research that has already been accomplished in the MSG, and an overview of the facility enhancements that will shortly be available for use by future investigators.

Strategy for preventing the waste of human resources

Jones, William E.

Rapid technological advances and the declining educational preparedness of industrial workers has established a need for new training strategies and initiatives regarding human resource development. The productivity, competitiveness, motivation, and creativity of our people determines whether our business enterprises succeed or fail during the next decade. Due to a change process that many organizations have undertaken to become more competitive toward the year 2000, many of the previous styles of engineering leadership that involves the management of projects and human resources require new approaches. It is also important to recognize that technology has its limits and a broader focus to include the human aspects of accomplishing jobs over the long term is more critical than ever before. More autonomy and the responsibility for broader practices by the professional staff requires that the professional worker operate differently. Business planning and development of the organization's future strategic intent requires a high priority on the human resource linkage to the business plans and strategies. A review of past practices to motivate the worker toward higher productivity clearly shows that past techniques are not as effective in today's work environment. Many practices of organizational and individual leadership don't fit today's approach of worker involvement because they were designed for administrative supervisory control processes. Therefore, if we are going to organize a business strategy that prevents the `waste of human resources,' we need to develop a strategy that is appropriate for the times which considers the attitude of the employees and their work environment. Having worked with scientists and engineers for the majority of my twenty-five year career, I know they see and appreciate the logic of a formula. A formula fits when developing a future strategy because a formula can become a model to enhance balanced planning. In this paper, I want to share this simple formula and illustrate how I have utilized it as a tool for workshop discussions, and human resources planning purposes.

A global and local discussion on Public Health relevance is taking place, including the future role and organization of its services. Noteworthy becomes the role played by Public Health Specialists. This work presents the results of a workshop, carried out following the Guilbert methodology, whose aim was to define Public Health Doctors functions and their related activities. The programme involved 30 professionals from Triveneto area (North Eastern Italy), working in Prevention Departments at National Health Service and Universities. The key-functions identified were: 1) Health status assessment and identification of community risk factors, 2) Health Promotion, 3) Prevention, 4) Protection, 5) Planning, 6) Communication, 7) Professional Training, 8) Alliances and resources for complex Public Health programs, 9) Crisis management in Public Health, 10) Research. For each function activities were identified, meaning concerning areas and contents that must be warranted by professionals. This experience allowed to share existing attitudes and experiences present in Triveneto area, and it can stand as a feasible instrument for different settings. Nevertheless, it appears mandatory explaining at each level in the society role and functions of Prevention Departments.

Optical communications offer a capable alternative to radio frequency (RF) communications for applications where high data-rate is required. This technology is particularly promising and challenging in the field of future inter-satellite communications. The term laser satellite communications (LSC) stands for optical links between satellites and/or high altitude platforms (HAPs). However, optical links between an earth station and a satellite or HAPs can be also involved. This work gives an overview of nowadays laser satellite communications. Particularly, it is focused on the factors causing degradation of the optical beam in the atmosphere. If an optical link passes through the atmosphere, it suffers from various influences such as attenuation due to absorption and scattering, intensity fluctuations due to atmospheric turbulence and background radiation. Furthermore, platform vibrations cause mispointing and following tracking losses. Suitable devices and used pointing and tracking system for laser satellite communications are discussed. At the end, various scenarios of the optical links and calculations of their power link budgets and limitations are designed. Implemented software is used for calculation of optical links. This work proves that the Free Space Optics (FSO) systems on mobile platforms, like satellites and HAPs are a promising solution for future communication networks.

What differentiates episodic future thinking from complex scene imagery?

We investigated the contributions of familiarity of setting, self-relevance and self-projection in time to episodic future thinking. The role of familiarity of setting was assessed, in Experiment 1, by comparing episodic future thoughts to autobiographical future events supposed to occur in unfamiliar settings. The role of self-relevance was assessed, in Experiment 2, by comparing episodic future thoughts to future events involving familiar others. The role of self-projection in time was assessed, in both Experiments, by comparing episodic future thoughts to autobiographical events that were not temporal in nature. Results indicated that episodic future thoughts were more clearly represented than autobiographical future events occurring in unfamiliar setting and future events involving familiar others. Our results also revealed that episodic future thoughts were indistinguishable from autobiographical atemporal events with respect to both subjective and objective detail ratings. These results suggest that future and atemporal events are mentally represented in a similar way. Copyright © 2012 Elsevier Inc. All rights reserved.

The domestic response to the West Africa Ebola virus disease (EVD) epidemic from 2014-2016 provides a unique opportunity to distill lessons learned about health sector planning and operations from those individuals directly involved. This research project aimed to identify and integrate these lessons into an actionable checklist that can improve health sector resilience to future high-consequence infectious disease (HCID) events. Interviews (N = 73) were completed with individuals involved in the domestic EVD response in 4 cities (Atlanta, Dallas, New York, and Omaha), and included individuals who worked in academia, emergency management, government, health care, law, media, and public health during the response. Interviews were transcribed and analyzed qualitatively. Two focus groups were then conducted to expand on themes identified in the interviews. Using these themes, an evidence-informed checklist was developed and vetted for completeness and feasibility by an expert advisory group. Salient themes identified included health care facility issues-specifically identifying assessment and treatment hospitals, isolation and treatment unit layout, waste management, community relations, patient identification, patient isolation, limitations on treatment, laboratories, and research considerations-and health care workforce issues-specifically psychosocial impact, unit staffing, staff training, and proper personal protective equipment. The experiences of those involved in the domestic Ebola response provide critical lessons that can help strengthen resilience of health care systems and improve future responses to HCID events.

Phases of "pre-engagement" capacity building: discovery, exploration, and trial alliance.

PubMed

Campbell-Voytal, Kimberly

2010-01-01

Academic prevention researchers who engage limited-resource communities may find that organizational or community capacity for prevention is low. Community organizations, neighborhoods, and academic partners may lack shared issue awareness, mutual interests, and interactive skills necessary for collaborative intervention. Existing capacity building models either ignore a 'pre-engagement' phase or acknowledge it without offering strategic detail. An exploratory or developmental phase before active engagement can be achieved through co-located work in a community setting. The construct, "ecology of practice," provides conceptual background for examining how "shared work" introduces and prepares partners for future collaboration consistent with community-based participatory research (CBPR) principles. This paper presents two case studies where pre-engagement capacity building involved partners who were initially unaware, disinterested, or unable to engage in preventive interventions. These cases illustrate how mutual participation in shared "ecologies of practice" enabled an exchange of cultural knowledge, skill, and language that laid the groundwork for future preventive intervention. A trajectory of developmental work in each case occurred over 5 years. Historical timelines, interviews, and personal communications between community and academic leaders were reviewed and common themes identified. A model of "pre-capacity building" emerged. Capacity-building models that detail strategies for developing equitable engagement in under-resourced settings will more effectively move best practices into vulnerable communities. Preventive interventions must be translated equitably if health disparities are to be reduced.

Reducing hospital readmission rates: current strategies and future directions.

PubMed

Kripalani, Sunil; Theobald, Cecelia N; Anctil, Beth; Vasilevskis, Eduard E

2014-01-01

New financial penalties for institutions with high readmission rates have intensified efforts to reduce rehospitalization. Several interventions that involve multiple components (e.g., patient needs assessment, medication reconciliation, patient education, arranging timely outpatient appointments, and providing telephone follow-up) have successfully reduced readmission rates for patients discharged to home. The effect of interventions on readmission rates is related to the number of components implemented; single-component interventions are unlikely to reduce readmissions significantly. For patients discharged to postacute care facilities, multicomponent interventions have reduced readmissions through enhanced communication, medication safety, advanced care planning, and enhanced training to manage medical conditions that commonly precipitate readmission. To help hospitals direct resources and services to patients with greater likelihood of readmission, risk-stratification methods are available. Future work should better define the roles of home-based services, information technology, mental health care, caregiver support, community partnerships, and new transitional care personnel.

Relativistic, model-independent, multichannel 2 → 2 transition amplitudes in a finite volume

DOE PAGES

Briceno, Raul A.; Hansen, Maxwell T.

2016-07-13

We derive formalism for determining 2 + J → 2 infinite-volume transition amplitudes from finite-volume matrix elements. Specifically, we present a relativistic, model-independent relation between finite-volume matrix elements of external currents and the physically observable infinite-volume matrix elements involving two-particle asymptotic states. The result presented holds for states composed of two scalar bosons. These can be identical or non-identical and, in the latter case, can be either degenerate or non-degenerate. We further accommodate any number of strongly-coupled two-scalar channels. This formalism will, for example, allow future lattice QCD calculations of themore » $$\\rho$$-meson form factor, in which the unstable nature of the $$\\rho$$ is rigorously accommodated. In conclusion, we also discuss how this work will impact future extractions of nuclear parity and hadronic long-range matrix elements from lattice QCD.« less

Who Provides Care? A Prospective Study of Caregiving Among Adult Siblings

Pillemer, Karl; Suitor, J. Jill

2014-01-01

Purpose: We use data from a longitudinal, within-family study to identify factors that predict which adult siblings assumed caregiving responsibilities to older mothers over a 7-year period. Design and Methods: Data for the study were collected from 139 older mothers at 2 points 7 years apart regarding their expectations and experiences of care from 537 adult children. Results: Children whom mothers identified at T1 as their expected future caregivers were much more likely to provide care when a serious illness occurred. Caregiving offspring were also more likely at T1 to have shared their mothers’ values, lived in proximity, and to be daughters. Implications: The findings indicate the degree to which a mother’s expectations for care predict actual caregiving by that child. Practitioners working with older adults should explore parents’ expectations for future care that involves their adult children. PMID:23840019

Team-Based Care with Pharmacists to Improve Blood Pressure: a Review of Recent Literature.

2018-01-18

We review studies published since 2014 that examined team-based care strategies and involved pharmacists to improve blood pressure (BP). We then discuss opportunities and challenges to sustainment of team-based care models in primary care clinics. Multiple studies presented in this review have demonstrated that team-based care including pharmacists can improve BP management. Studies highlighted the cost-effectiveness of a team-based pharmacy intervention for BP control in primary care clinics. Little information was found on factors influencing sustainability of team-based care interventions to improve BP control. Future work is needed to determine the best populations to target with team-based BP programs and how to implement team-based approaches utilizing pharmacists in diverse clinical settings. Future studies need to not only identify unmet clinical needs but also address reimbursement issues and stakeholder engagement that may impact sustainment of team-based care interventions.

BCI Use and Its Relation to Adaptation in Cortical Networks.

2017-10-01

Brain-computer interfaces (BCIs) carry great potential in the treatment of motor impairments. As a new motor output, BCIs interface with the native motor system, but acquisition of BCI proficiency requires a degree of learning to integrate this new function. In this review, we discuss how BCI designs often take advantage of the brain's motor system infrastructure as sources of command signals. We highlight a growing body of literature examining how this approach leads to changes in activity across cortex, including beyond motor regions, as a result of learning the new skill of BCI control. We discuss the previous research identifying patterns of neural activity associated with BCI skill acquisition and use that closely resembles those associated with learning traditional native motor tasks. We then discuss recent work in animals probing changes in connectivity of the BCI control site, which were linked to BCI skill acquisition, and use this as a foundation for our original work in humans. We present our novel work showing changes in resting state connectivity across cortex following the BCI learning process. We find substantial, heterogeneous changes in connectivity across regions and frequencies, including interactions that do not involve the BCI control site. We conclude from our review and original work that BCI skill acquisition may potentially lead to significant changes in evoked and resting state connectivity across multiple cortical regions. We recommend that future studies of BCIs look beyond motor regions to fully describe the cortical networks involved and long-term adaptations resulting from BCI skill acquisition.

Progress in the development and future requirements of the Variable Stream Control Engine (VSCE) are presented. The two most critical components of this advanced system for future supersonic transports, the high performance duct burner for thrust augmentation, and the low jet coannular nozzle were studied. Nozzle model tests substantiated the jet noise benefit associated with the unique velocity profile possible with a coannular nozzle system on a VSCE. Additional nozzle model performance tests have established high thrust efficiency levels only at takeoff and supersonic cruise for this nozzle system. An experimental program involving both isolated component and complete engine tests has been conducted for the high performance, low emissions duct burner with good results and large scale testing of these two components is being conducted using a F100 engine as the testbed for simulating the VSCE. Future work includes application of computer programs for supersonic flow fields to coannular nozzle geometries, further experimental testing with the duct burner segment rig, and the use of the Variable Cycle Engine (VCE) Testbed Program for evaluating the VSCE duct burner and coannular nozzle technologies.

Lithium-ion batteries are crucial to the future of energy storage. However, the energy density of current lithium-ion batteries is insufficient for future applications. Sulfur cathodes and silicon anodes have garnered a lot of attention in the field due their high capacity potential. Although recent developments in sulfur and silicon electrodes show exciting results in half cell formats, neither electrode can act as a lithium source when put together into a full cell format. Current methods toward incorporating lithium in sulfur-silicon full cells involves prelithiating silicon or using lithium sulfide. These methods however, complicate material processing and creates safety hazards. Herein, we present a novel full cell battery architecture that bypasses the issues associated with current methods. This battery architecture gradually integrates controlled amounts of pure lithium into the system by allowing lithium the access to external circuit. A high specific energy density of 350 Wh/kg after 250 cycles at C/10 was achieved using this method. This work should pave the way for future researches into sulfur-silicon full cells.

Although research shows that “food parenting practices” can impact children’s diet and eating habits, current understanding of the impact of specific practices has been limited by inconsistencies in terminology and definitions. This article represents a critical appraisal of food parenting practices, including clear terminology and definitions, by a working group of content experts. The result of this effort was the development of a content map for future research that presents 3 overarching, higher-order food parenting constructs – coercive control, structure, and autonomy support – as well as specific practice subconstructs. Coercive control includes restriction, pressure to eat, threats and bribes, and using food to control negative emotions. Structure includes rules and limits, limited/guided choices, monitoring, meal- and snacktime routines, modeling, food availability and accessibility, food preparation, and unstructured practices. Autonomy support includes nutrition education, child involvement, encouragement, praise, reasoning, and negotiation. Literature on each construct is reviewed, and directions for future research are offered. Clear terminology and definitions should facilitate cross-study comparisons and minimize conflicting findings resulting from previous discrepancies in construct operationalization. PMID:26724487

Non-resonant collider signatures of a singlet-driven electroweak phase transition

2017-08-01

We analyze the collider signatures of the real singlet extension of the Standard Model in regions consistent with a strong first-order electroweak phase transition and a singlet-like scalar heavier than the Standard Model-like Higgs. A definitive correlation exists between the strength of the phase transition and the trilinear coupling of the Higgs to two singlet-like scalars, and hence between the phase transition and non-resonant scalar pair production involving the singlet at colliders. We study the prospects for observing these processes at the LHC and a future 100 TeV pp collider, focusing particularly on double singlet production. We also discuss correlations between the strength of the electroweak phase transition and other observables at hadron and future lepton colliders. Searches for non-resonant singlet-like scalar pair production at 100 TeV would provide a sensitive probe of the electroweak phase transition in this model, complementing resonant di-Higgs searches and precision measurements. Our study illustrates a strategy for systematically exploring the phenomenologically viable parameter space of this model, which we hope will be useful for future work.

Support for designing waste sorting systems: A mini review.

Rousta, Kamran; Ordoñez, Isabel; Bolton, Kim; Dahlén, Lisa

2017-11-01

This article presents a mini review of research aimed at understanding material recovery from municipal solid waste. It focuses on two areas, waste sorting behaviour and collection systems, so that research on the link between these areas could be identified and evaluated. The main results presented and the methods used in the articles are categorised and appraised. The mini review reveals that most of the work that offered design guidelines for waste management systems was based on optimising technical aspects only. In contrast, most of the work that focused on user involvement did not consider developing the technical aspects of the system, but was limited to studies of user behaviour. The only clear consensus among the articles that link user involvement with the technical system is that convenient waste collection infrastructure is crucial for supporting source separation. This mini review reveals that even though the connection between sorting behaviour and technical infrastructure has been explored and described in some articles, there is still a gap when using this knowledge to design waste sorting systems. Future research in this field would benefit from being multidisciplinary and from using complementary methods, so that holistic solutions for material recirculation can be identified. It would be beneficial to actively involve users when developing sorting infrastructures, to be sure to provide a waste management system that will be properly used by them.

Thin film processing technologies that promise atomic and molecular scale control have received increasing interest in the past several years, as traditional methods for fabrication begin to reach their fundamental limits. Many of these technologies involve at their heart phenomena occurring at or near surfaces, including adsorption, gas-surface reactions, diffusion, desorption, and re-organization of near-surface layers. Moreover many of these phenomena involve not just reactions occurring under conditions of local thermodynamic equilibrium but also the action of energetic species including electrons, ions, and hyperthermal neutrals. There is a rich landscape of atomic and molecular scale interactions occurring in these systems that is still not well understood. In this Special Topic Issue of The Journal of Chemical Physics, we have collected recent representative examples of work that is directed at unraveling the mechanistic details concerning atomic and molecular layer processing, which will provide an important framework from which these fields can continue to develop. These studies range from the application of theory and computation to these systems to the use of powerful experimental probes, such as X-ray synchrotron radiation, probe microscopies, and photoelectron and infrared spectroscopies. The work presented here helps in identifying some of the major challenges and direct future activities in this exciting area of research involving atomic and molecular layer manipulation and fabrication.

These studies range from the application of theory and computation to these systems to the use of powerful experimental probes, such as X-ray synchrotron radiation, probe microscopies, and photoelectron and infrared spectroscopies. The work presented here helps in identifying some of the major challenges and direct future activities in this exciting area of research involving atomic and molecular layer manipulation and fabrication.

A framework of knowledge creation processes in participatory simulation of hospital work systems.

PubMed

Andersen, Simone Nyholm; Broberg, Ole

2017-04-01

Participatory simulation (PS) is a method to involve workers in simulating and designing their own future work system. Existing PS studies have focused on analysing the outcome, and minimal attention has been devoted to the process of creating this outcome. In order to study this process, we suggest applying a knowledge creation perspective. The aim of this study was to develop a framework describing the process of how ergonomics knowledge is created in PS. Video recordings from three projects applying PS of hospital work systems constituted the foundation of process mining analysis. The analysis resulted in a framework revealing the sources of ergonomics knowledge creation as sequential relationships between the activities of simulation participants sharing work experiences; experimenting with scenarios; and reflecting on ergonomics consequences. We argue that this framework reveals the hidden steps of PS that are essential when planning and facilitating PS that aims at designing work systems. Practitioner Summary: When facilitating participatory simulation (PS) in work system design, achieving an understanding of the PS process is essential. By applying a knowledge creation perspective and process mining, we investigated the knowledge-creating activities constituting the PS process. The analysis resulted in a framework of the knowledge-creating process in PS.

Increasing use of emergency departments among older patients with palliative needs has led to the development of several service-level interventions intended to improve care quality. There is little evidence of patient and family involvement in developmental processes, and little is known about the experiences of - and preferences for - palliative care delivery in this setting. Participatory action research seeking to enable collaborative working between patients and staff should enhance the impact of local quality improvement work but has not been widely implemented in such a complex setting. To critique the feasibility of this methodology as a quality improvement intervention in complex healthcare settings, laying a foundation for future work. an Emergency Department in a large teaching hospital in the United Kingdom. Experience-based Co-design incorporating: 150h of nonparticipant observation; semi-structured interviews with 15 staff members about their experiences of palliative care delivery; 5 focus groups with 64 staff members to explore challenges in delivering palliative care; 10 filmed semi-structured interviews with palliative care patients or their family members; a co-design event involving staff, patients and family members. the study successfully identified quality improvement priorities leading to changes in Emergency Department-palliative care processes. Further outputs were the creation of a patient-family-staff experience training DVD to encourage reflective discussion and the identification and application of generic design principles for improving palliative care in the Emergency Department. There were benefits and challenges associated with using Experience-based Co-design in this setting. Benefits included the flexibility of the approach, the high levels of engagement and responsiveness of patients, families and staff, and the impact of using filmed narrative interviews to enhance the 'voice' of seldom heard patients and families. Challenges included high levels of staff turnover during the 19 month project, significant time constraints in the Emergency Department and the ability of older patients and their families to fully participate in the co-design process. Experience-based Co-design is a useful approach for encouraging collaborative working between vulnerable patients, family and staff in complex healthcare environments. The flexibility of the approach allows the specific needs of participants to be accounted for, enabling fuller engagement with those who typically may not be invited to contribute to quality improvement work. Recommendations for future studies in this and similar settings include testing the 'accelerated' form of the approach and experimenting with alternative ways of increasing involvement of patients/families in the co-design phase.

From the past to the future: Integrating work experience into the design process.

PubMed

Bittencourt, João Marcos; Duarte, Francisco; Béguin, Pascal

2017-01-01

Integrating work activity issues into design process is a broadly discussed theme in ergonomics. Participation is presented as the main means for such integration. However, a late participation can limit the development of both project solutions and future work activity. This article presents the concept of construction of experience aiming at the articulated development of future activities and project solutions. It is a non-teleological approach where the initial concepts will be transformed by the experience built up throughout the design process. The method applied was a case study of an ergonomic participation during the design of a new laboratory complex for biotechnology research. Data was obtained through analysis of records in a simulation process using a Lego scale model and interviews with project participants. The simulation process allowed for developing new ways of working and generating changes in the initial design solutions, which enable workers to adopt their own developed strategies for conducting work more safely and efficiently in the future work system. Each project decision either opens or closes a window of opportunities for developing a future activity. Construction of experience in a non-teleological design process allows for understanding the consequences of project solutions for future work.

Frequency Spectrum for New Aviation Data Links: Initial Study Results

Matolak, David W.; Branstetter, James R.

2004-01-01

We describe results from an initial study to assess the suitability of various spectral bands for supporting the deployment of new aviation data links (ADL). The study focused on systems and spectral bands that can deliver VHF data link (VDL)-or-higher data rates in a two-way communication setting, including air-ground, ground-air, and air-air modes of operation. In the first part of our paper, we briefly discuss the current situation regarding communications, navigation, and surveillance (CNS) links and existing spectrum, and the well-known need for new aviation data links. We next provide an overview of related systems, and discuss key factors involved in the use of spectrum in various bands for any future integrated CNS data link, addressing primarily the lower few layers of the communications protocol stack. Desired attributes of a new ADL system are discussed, and the beneficial aspects of a particular transmission technique spread spectrum are summarized. We also provide a short list of several example potential spectral regions, and note that while none of the existing systems will likely meet the full range of desired features of a new ADL, several systems and spectral regions offer promise in terms of one or more characteristics. A detailed discussion and evaluation of these spectral regions is proposed as future work. We include a few brief examples to illustrate initial technical results regarding spread spectrum overlay, also a subject for future work.

The neurobiology of emotion–cognition interactions: fundamental questions and strategies for future research

2015-01-01

Recent years have witnessed the emergence of powerful new tools for assaying the brain and a remarkable acceleration of research focused on the interplay of emotion and cognition. This work has begun to yield new insights into fundamental questions about the nature of the mind and important clues about the origins of mental illness. In particular, this research demonstrates that stress, anxiety, and other kinds of emotion can profoundly influence key elements of cognition, including selective attention, working memory, and cognitive control. Often, this influence persists beyond the duration of transient emotional challenges, partially reflecting the slower molecular dynamics of catecholamine and hormonal neurochemistry. In turn, circuits involved in attention, executive control, and working memory contribute to the regulation of emotion. The distinction between the ‘emotional’ and the ‘cognitive’ brain is fuzzy and context-dependent. Indeed, there is compelling evidence that brain territories and psychological processes commonly associated with cognition, such as the dorsolateral prefrontal cortex and working memory, play a central role in emotion. Furthermore, putatively emotional and cognitive regions influence one another via a complex web of connections in ways that jointly contribute to adaptive and maladaptive behavior. This work demonstrates that emotion and cognition are deeply interwoven in the fabric of the brain, suggesting that widely held beliefs about the key constituents of ‘the emotional brain’ and ‘the cognitive brain’ are fundamentally flawed. We conclude by outlining several strategies for enhancing future research. Developing a deeper understanding of the emotional-cognitive brain is important, not just for understanding the mind but also for elucidating the root causes of its disorders. PMID:25774129

Several children's hospitals and medical schools across Texas have child abuse pediatricians (CAPs) who work closely with child protection workers to help ensure accurate assessments of the likelihood of maltreatment in cases of suspected abuse and neglect. Since the state does not mandate which cases should be referred to a CAP center, we were interested in studying factors that may influence workers' decisions to consult a CAP. We used a mixed methods study design consisting of a focus group followed by a survey. The focus group identified multiple factors that impact workers' decision-making, including several that involve medical providers. Responses from 436 completed surveys were compared to employees' number of years of employment and to the state region in which they worked. Focus group findings and survey responses revealed frustration among many workers when dealing with medical providers, and moderate levels of confidence in workers' abilities to make accurate determinations in cases involving medical information. Workers were more likely to refer cases involving serious physical injury than other types of cases. Among workers who reported prior interactions with a CAP, experiences and attitudes regarding CAPs were typically positive. The survey also revealed significant variability in referral practices by state region. Our results suggest that standard guidelines regarding CAP referrals may help workers who deal with cases involving medical information. Future research and quality improvement efforts to improve transfers of information and to better understand the qualities that CPS workers appreciate in CAP teams should improve CAP-CPS coordination.

Walker, James L.; Workman, Gary L.

1997-01-01

The nondestructive evaluation (NDE) of future propulsion systems utilizing advanced composite structures for the storage of cryogenic fuels, such as liquid hydrogen or oxygen, presents many challenges. Economic justification for these structures requires, light weight, reusable components with an infrastructure allowing periodic evaluation of structural integrity after enduring demanding stresses during operation. A major focus has been placed on the use of acoustic emission NDE to detect propagating defects, in service, necessitating an extensive study into characterizing the nature of acoustic signal propagation at very low temperatures and developing the methodology of applying AE sensors to monitor cryogenic components. This work addresses the question of sensor performance in the cryogenic environment. Problems involving sensor mounting, spectral response and durability are addressed. The results of this work provides a common point of measure from which sensor selection can be made when testing composite components at cryogenic temperatures.

A Realtime Active Feedback Control System For Coupled Nonlinear Chemical Oscillators

Tompkins, Nathan; Fraden, Seth

2012-02-01

We study the manipulation and control of oscillatory networks. As a model system we use an emulsion of Belousov-Zhabotinsky (BZ) oscillators packed on a hexagonal lattice. Each drop is observed and perturbed by a Programmable Illumination Microscope (PIM). The PIM allows us to track individual BZ oscillators, calculate the phase and order parameters of every drop, and selectively perturb specific drops with photo illumination, all in realtime. To date we have determined the native attractor patterns for drops in 1D arrays and 2D hexagonal packing as a function of coupling strength as well as determined methods to move the system from one attractor basin to another. Current work involves implementing these attractor control methods with our experimental system and future work will likely include implementing a model neural network for use with photo controllable BZ emulsions.

Achieving equal pay for comparable worth through arbitration.

PubMed

Wisniewski, S C

1982-01-01

Traditional "women's jobs" often pay relatively low wages because of the effects of institutionalized stereotypes concerning women and their role in the work place. One way of dealing with sex discrimination that results in job segregation is to narrow the existing wage differential between "men's jobs" and "women's jobs." Where the jobs are dissimilar on their face, this narrowing of pay differences involves implementing the concept of "equal pay for jobs of comparable worth." Some time in the future, far-reaching, perhaps even industrywide, reductions in male-female pay differentials may be achieved by pursuing legal remedies based on equal pay for comparable worth. However, as the author demonstrates, immediate, albeit more limited, relief for sex-based pay inequities found in specific work places can be obtained by implementing equal pay for jobs of comparable worth through the collective bargaining and arbitration processes.

Results are reported of the first experiments for a computer conference management information system at the National Aeronautics and Space Administration. Between August 1975 and March 1976, two NASA projects with geographically separated participants (NASA scientists) used the PLANET computer conferencing system for portions of their work. The first project was a technology assessment of future transportation systems. The second project involved experiments with the Communication Technology Satellite. As part of this project, pre- and postlaunch operations were discussed in a computer conference. These conferences also provided the context for an analysis of the cost of computer conferencing. In particular, six cost components were identified: (1) terminal equipment, (2) communication with a network port, (3) network connection, (4) computer utilization, (5) data storage and (6) administrative overhead.

Since 2014 the Museum of the History of Physics of the University of Padua has been working on the study and valorisation of the collection of historical scientific instruments kept at the high school "Scipione Maffei" in Verona, one of the oldest high schools in Italy. The Cabinet of Physics of "Liceo Maffei", founded in 1802, currently consists of about 550 instruments, acquired until the 1960s. Besides the Museum's staff, the project has involved two physics teachers and a group of students, who participated in different phases of the work on the collection. This article intends to present the collection, the project, and the results achieved so far. We also aim at highlighting the potentialities and possible future developments of the project, a project which can become a model for other schools.

"The burden of financing retirement incomes in an ageing population is predicted to rise sharply in future decades. This paper investigates the effects of reforms to the Australian tax-benefit system involving a greater reliance on proportional taxation for raising revenue and a more targeted welfare system for cutting government expenditure, in order to reduce expected budget deficits. Estimates of changes in net incomes and hours of work suggest that reforms of this kind shift the tax burden to lower and middle income households with a second earner and that they can have counter-productive labour supply effects. The study explores the impact of projected increases in female work force participation and illustrates the importance of shifts in the labour supply of married women in predicting the fiscal effects of demographic change." excerpt

Designing the safety of healthcare. Participation of ergonomics to the design of cooperative systems in radiotherapy.

This communication deals with the involvement of ergonomists in a research-action design process of a software platform in radiotherapy. The goal of the design project is to enhance patient safety by designing a workflow software that supports cooperation between professionals producing treatment in radiotherapy. The general framework of our approach is the ergonomics management of a design process, which is based in activity analysis and grounded in participatory design. Two fields are concerned by the present action: a design environment which is a participatory design process that involves software designers, caregivers as future users and ergonomists; and a reference real work setting in radiotherapy. Observations, semi-structured interviews and participatory workshops allow the characterization of activity in radiotherapy dealing with uses of cooperative tools, sources of variability and non-ruled strategies to manage the variability of the situations. This production of knowledge about work searches to enhance the articulation between technocentric and anthropocentric approaches, and helps in clarifying design requirements. An issue of this research-action is to develop a framework to define the parameters of the workflow tool, and the conditions of its deployment.

Many people confronting mental health problems are excluded from participation in paid work. Supervisor engagement is essential for successful job placement. To elicit supervisor perspectives on the challenges involved in fostering integration to support individuals with mental health problems (trainees) in their job placement at ordinary companies. Explorative, qualitative designed study with a phenomenological approach, based on semi-structured interviews with 15 supervisors involved in job placements for a total of 105 trainees (mean 7, min-max. 1-30, SD 8). Data were analysed using qualitative content analysis. Superviors experience two interrelated dilemmas concerning knowledge of the trainee and degree of preferential treatment. Challenges to obtaining successful integration were; motivational: 1) Supervisors previous experience with trainees encourages future engagement, 2) Developing a realistic picture of the situation, and 3) Disclosure and knowledge of mental health problems, and continuity challenges: 4) Sustaining trainee cooperation throughout the placement process, 5) Building and maintaining a good relationship between supervisor and trainee, and 6) Ensuring continuous cooperation with the social security system and other stakeholders. Supervisors experience relational dilemmas regarding pre-judgment, privacy and equality. Job placement seem to be maximized when the stakeholders are motivated and recognize that cooperation must be a continuous process.

Bioinspired turbine blades offer new perspectives for wind energy

NASA Astrophysics Data System (ADS)

Cognet, V.; Courrech du Pont, S.; Dobrev, I.; Massouh, F.; Thiria, B.

2017-02-01

Wind energy is becoming a significant alternative solution for future energy production. Modern turbines now benefit from engineering expertise, and a large variety of different models exists, depending on the context and needs. However, classical wind turbines are designed to operate within a narrow zone centred around their optimal working point. This limitation prevents the use of sites with variable wind to harvest energy, involving significant energetic and economic losses. Here, we present a new type of bioinspired wind turbine using elastic blades, which passively deform through the air loading and centrifugal effects. This work is inspired from recent studies on insect flight and plant reconfiguration, which show the ability of elastic wings or leaves to adapt to the wind conditions and thereby to optimize performance. We show that in the context of energy production, the reconfiguration of the elastic blades significantly extends the range of operating regimes using only passive, non-consuming mechanisms. The versatility of the new turbine model leads to a large increase of the converted energy rate, up to 35%. The fluid/elasticity mechanisms involved for the reconfiguration capability of the new blades are analysed in detail, using experimental observations and modelling.

Perceptions of vulnerability to a future outbreak: a study of horse managers affected by the first Australian equine influenza outbreak

PubMed Central

2013-01-01

Background A growing body of work shows the benefits of applying social cognitive behavioural theory to investigate infection control and biosecurity practices. Protection motivation theory has been used to predict protective health behaviours. The theory outlines that a perception of a lack of vulnerability to a disease contributes to a reduced threat appraisal, which results in poorer motivation, and is linked to poorer compliance with advised health protective behaviours. This study, conducted following the first-ever outbreak of equine influenza in Australia in 2007, identified factors associated with horse managers’ perceived vulnerability to a future equine influenza outbreak. Results Of the 200 respondents, 31.9% perceived themselves to be very vulnerable, 36.6% vulnerable and 31.4% not vulnerable to a future outbreak of equine influenza. Multivariable logistic regression modelling revealed that managers involved in horse racing and those on rural horse premises perceived themselves to have low levels of vulnerability. Managers of horse premises that experienced infection in their horses in 2007 and those seeking infection control information from specific sources reported increased levels of perceived vulnerability to a future outbreak. Conclusion Different groups across the horse industry perceived differing levels of vulnerability to a future outbreak. Increased vulnerability contributes to favourable infection control behaviour and hence these findings are important for understanding uptake of recommended infection control measures. Future biosecurity communication strategies should be delivered through information sources suitable for the horse racing and rural sectors. PMID:23902718

Using Agent-Based Models to Develop Public Policy about Food Behaviours: Future Directions and Recommendations.

2017-01-01

Most adults are overweight or obese in many western countries. Several population-level interventions on the physical, economical, political, or sociocultural environment have thus attempted to achieve a healthier weight. These interventions have involved different weight-related behaviours, such as food behaviours. Agent-based models (ABMs) have the potential to help policymakers evaluate food behaviour interventions from a systems perspective. However, fully realizing this potential involves a complex procedure starting with obtaining and analyzing data to populate the model and eventually identifying more efficient cross-sectoral policies. Current procedures for ABMs of food behaviours are mostly rooted in one technique, often ignore the food environment beyond home and work, and underutilize rich datasets. In this paper, we address some of these limitations to better support policymakers through two contributions. First, via a scoping review, we highlight readily available datasets and techniques to deal with these limitations independently. Second, we propose a three steps' process to tackle all limitations together and discuss its use to develop future models for food behaviours. We acknowledge that this integrated process is a leap forward in ABMs. However, this long-term objective is well-worth addressing as it can generate robust findings to effectively inform the design of food behaviour interventions.

Computational approaches have been major drivers behind the progress of proteomics in recent years. The aim of this white paper is to provide a framework for integrating computational proteomics into ELIXIR in the near future, and thus to broaden the portfolio of omics technologies supported by this European distributed infrastructure. This white paper is the direct result of a strategy meeting on 'The Future of Proteomics in ELIXIR' that took place in March 2017 in Tübingen (Germany), and involved representatives of eleven ELIXIR nodes. These discussions led to a list of priority areas in computational proteomics that would complement existing activities and close gaps in the portfolio of tools and services offered by ELIXIR so far. We provide some suggestions on how these activities could be integrated into ELIXIR's existing platforms, and how it could lead to a new ELIXIR use case in proteomics. We also highlight connections to the related field of metabolomics, where similar activities are ongoing. This white paper could thus serve as a starting point for the integration of computational proteomics into ELIXIR. Over the next few months we will be working closely with all stakeholders involved, and in particular with other representatives of the proteomics community, to further refine this paper.

Work hours and work-family conflict: the double-edged sword of involvement in work and family.

Matthews, Russell A; Swody, Cathleen A; Barnes-Farrell, Janet L

2012-08-01

In this study, we examine the role of work hours in a model that incorporates involvement in both work and family with experiences of work-family conflict and subjective well-being. Self-report data were collected from 383 full-time employees and analysed using structural equation modelling techniques. Results demonstrate that role salience was positively related to behavioural involvement with work and with family. In turn, behavioural family involvement was negatively related to work hours and family-to-work conflict, while behavioural work involvement was positively related to work hours. Behavioural family involvement was also positively related to life satisfaction. Finally, both family-to-work conflict and end-of-workday strain were negatively related to life satisfaction. Our results provide insight into unexpected problems that might arise when employees place overly high importance on work and work long hours. This study serves as a foundation for researchers to examine the interplay of time spent with work and family with other aspects of the work-family interface.

Coders noted speaker and recipient for alternatives, risks and benefits from 98 videotaped visits. Outcomes included discussion of alternatives, risks or benefits (yes/no) and involvement of parent or child in discussions (active or passive). Bivariate techniques were used to relate visit factors to outcomes. Most visits included discussion of alternatives (58% of visits), risks (54%) and benefits (69%). Longer visits were more likely to include risk discussions. For alternatives, active parent/child involvement was more likely with college graduate parents; for risks active involvement was more likely with female and more experienced physicians. Parents and children raised risks more frequently than benefits, often focusing on disadvantages such as taste or frequency/duration of therapy. Most pediatric visits include alternatives, risks and benefits but parent/child involvement in raising these topics is limited. When parents or children initiate these discussions, they often mention risks salient to adherence. Future work could explore whether longer visits or interventions targeted for specific participants could foster such discussions.

Abstract Objectives  To design and administer an attitude rating scale, exploring colorectal cancer patients’ views of involvement in decision making. To examine the impact of socio‐demographic and/or treatment‐related factors on decision making. To conduct principal components analysis to determine if the scale could be simplified into a number of factors for future clinical utility. Methods  An attitude rating scale was constructed based on previous qualitative work and administered to colorectal cancer patients using a cross‐sectional survey approach. Results  375 questionnaires were returned (81.7% response). For patients it was important to be informed and involved in the decision‐making process. Information was not always used to make decisions as patients placed their trust in medical expertise. Women had more positive opinions on decision making and were more likely to want to make decisions. Written information was understood to a greater degree than verbal information. The scale could be simplified to a number of factors, indicating clinical utility. Conclusion  Few studies have explored the attitudes of colorectal cancer patients towards involvement in decision making. This study presents new insights into how patients view the concept of participation; important when considering current policy imperatives in the UK of involving service users in all aspects of care and treatment.

The food industry is of great importance in Italy; it is second only to the engineering sector, involving about 440,000 workers. However, 90% of the food businesses have less than 10 employees and are exempt from legal obligation to provide a detailed Risk Assessment Document. The aim of the study was to identify the inconveniences and risks present in the workplaces analyzed with particular reference to biomechanical risk of the upper limbs and the lumbar spine. This preliminary study, carried out by using pre-mapping of the inconveniences and risks (5) and the "mini-checklist OCRA" (4), involved 15 small food businesses: ovens for baking bread, pastry shops, pizzerias and the production of "Piadina" (flat bread). Although undoubtedly with differences, confectioners, pasta makers, pizza makers and "piadinari" were exposed to similar risks. By analyzing the final graphs, action areas can be identified on which further risk analysis can be made. Exposure is mainly related to repetitive movements, manual handling of loads and a common occurrence is the risk of allergy to flour dust. There are real peaks in demand from customers, that inevitably increase work demands and consequently biomechanical overload. In future studies it will be interesting to investigate this aspect by studying the variations in work demand and the final exposure index of the working day.

Final Scientific Report: Bacterial Nanowires and Extracellular Electron Transfer to Heavy Metals and Radionuclides by Bacterial Isolates from DOE Field Research Centers

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

Nealson, Kenneth

This proposal involved the study of bacteria capable of transferring electrons from the bacterial cells to electron acceptors located outside the cell. These could be either insoluble minerals that were transformed into soluble products upon the addition of electrons, or they could be soluble salts like uranium or chromium, that become insoluble upon the addition of electrons. This process is called extracellular electron transport or EET, and can be done directly by cellular contact, or via conductive appendages called bacterial nanowires. In this work we examined a number of different bacteria for their ability to perform EET, and also lookedmore » at their ability to produce conductive nanowires that can be used for EET at a distance away from the EET-capable cells. In the work, new bacteria were isolated, new abilities of EET were examined, and many new methods were developed, and carefully described in the literature. These studies set the stage for future work dealing with the bioremediation of toxic metals like uranium and chromium. They also point out that EET (and conductive nanowires) are far more common that had been appreciated, and may be involved with energy transfer not only in sediments, but in symbioses between different bacteria, and in symbiosis/pathogenesis between bacteria and higher organisms.« less

Ethical and Safety Issues in Doing Sex Work Research: Reflections From a Field-Based Ethnographic Study in Kolkata, India

While much has been said about the risks and safety issues experienced by female sex workers in India, there is a considerable dearth of information about the difficulties and problems that sex work researchers, especially female researchers, experience when navigating the highly political, ideological, and stigmatized environment of the Indian sex industry. As noted by scholars, there are several methodological and ethical issues involved with sex work research, such as privacy and confidentiality of the participants, representativeness of the sample, and informed consent. Yet, there has been reluctance among scholars to comment on their research process, especially with regard to how they deal with the protocols for research ethics when conducting social and behavioral epidemiological studies among female sex workers in India and elsewhere. Drawing on my 7 months of field-based ethnographic research with “flying” or non-brothel-based female sex workers in Kolkata, India, I provide in this article a reflexive account of the problems encountered in implementing the research process, particularly the ethical and safety issues involved in gaining access and acceptance into the sex industry and establishing contact and rapport with the participants. In doing so, it is my hope that future researchers can develop the knowledge necessary for the design of ethical and non-exploitative research projects with sex workers. PMID:27651071

2017-01-01

Objectives While digital health technologies hold potential for improving healthcare and the generation and dissemination of health information, there are many issues to be resolved in facilitating their provision and efficacy and ensuring ethical management of personal health data. In the face of high-stakes digital health initiatives, debates and controversies, eliciting the views and experiences of the diverse constituents in the digital health ecosystem is important. Methods A digital health stakeholder workshop was held in Canberra, Australia, to address two key questions: 1) What is currently working and not working in digital health? and 2) Where should digital health go in the future? As part of a living lab approach, the 25 workshop participants from research, industry, patient and other healthcare consumer groups and government, engaged in participatory design activities directed at stimulating ideas and discussion. The design artefacts and videos generated during the workshop were thematically analysed. Results Digital health technologies offer valuable ways for healthcare consumers, providers, community groups and health industries to create and share information about health, medicine and healthcare. However, members of some social groups are currently excluded from full participation in the digital health ecosystem. Mechanisms for facilitating further consultation between the various stakeholders involved in digital health, including patients and carers, need to be established. The rights and responsibilities of the different stakeholders involved in connected digital health also need to be better identified and highlighted. At the same time, personal data privacy and security need protection. Conclusion Establishing the effective and responsible delivery of digital health technologies and collection, protection and sharing of health data is highly complex. Infrastructure, ethical and social issues need to be considered. PMID:29942616

My involvement with the field of cannabinoids spans close to three decades, and covers a major part of my scientific career. It also reflects the robust progress in this initially largely unexplored area of biology. During this period of time, I have witnessed the growth of modern cannabinoid biology, starting from the discovery of its two receptors and followed by the characterization of its endogenous ligands and the identification of the enzyme systems involved in their biosynthesis and biotransformation. I was fortunate enough to start at the beginning of this new era and participate in a number of the new discoveries. It has been a very exciting journey. By covering some key aspects of my work during this period of “modern cannabinoid research,” this perspective, in part historical, intends to give an account of how the field grew, the key discoveries, and the most promising directions for the future.

Although many reviews exist characterizing the molecular differences of GABAB receptor isoforms, there is no current review of the in vivo effects of these isoforms. The current review focuses on whether the GABAB1a and GABAB1b isoforms contribute differentially to behaviors in isoform knockout mice. The roles of these receptors have primarily been characterized in cognitive, anxiety, and depressive phenotypes. Currently, the field supports a role of GABAB1a in memory maintenance and protection against an anhedonic phenotype, whereas GABAB1b appears to be involved in memory formation and a susceptibility to developing an anhedonic phenotype. Although GABAB receptors have been strongly implicated in drug abuse phenotypes, no isoform-specific work has been done in this field. Future directions include developing site-specific isoform knockdown to identify the role of different brain regions in behavior, as well as identifying how these isoforms are involved in development of behavioral phenotypes.

Dry edible bean (Phaseolus vulgaris L.) is a globally relevant food crop. The bean genome was recently sequenced and annotated allowing for proteomics investigations aimed at characterization of leaf phenotypes important to agriculture. The objective of this study was to utilize a shotgun proteomics approach to characterize the leaf proteome and to identify protein abundance differences between two bean lines with known variation in their physiological resistance to biotic stresses. Overall, 640 proteins were confidently identified. Among these are proteins known to be involved in a variety of molecular functions including oxidoreductase activity, binding peroxidase activity, and hydrolase activity. Twenty nine proteins were found to significantly vary in abundance (p-value < 0.05) between the two bean lines, including proteins associated with biotic stress. To our knowledge, this work represents the first large scale shotgun proteomic analysis of beans and our results lay the groundwork for future studies designed to investigate the molecular mechanisms involved in pathogen resistance.

This work involves designing and simulation of a PV source based high voltage gain, current fed converter. It deals with an isolated DC-DC converter which utilizes boost converter topology. The proposed converter is capable of high voltage gain and above all have very high efficiency levels as proved by the simulation results. The project intends to produce an output of 800 V dc from a 48 V dc input. The simulation results obtained from PSIM application interface were used to analyze the performance of the proposed converter. Transformer used in the circuit steps up the voltage as well as to provide electrical isolation between the low voltage and high voltage side. Since the converter involves high switching frequency of 100 kHz, ultrafast recovery diodes are employed in the circuitry. The major application of the project is for future modeling of solar powered electric hybrid cars.

Autonomous Vehicle technology is quickly expanding its market and has found in Silicon Valley, California, a strong foothold for preliminary testing on public roads. In an effort to promote safety and transparency to consumers, the California Department of Motor Vehicles has mandated that reports of accidents involving autonomous vehicles be drafted and made available to the public. The present work shows an in-depth analysis of the accident reports filed by different manufacturers that are testing autonomous vehicles in California (testing data from September 2014 to March 2017). The data provides important information on autonomous vehicles accidents’ dynamics, related to the most frequent types of collisions and impacts, accident frequencies, and other contributing factors. The study also explores important implications related to future testing and validation of semi-autonomous vehicles, tracing the investigation back to current literature as well as to the current regulatory panorama.

The objectives in this article are the exploration of demographic and service usage data gained through clinical data mining audit and suggesting recommendations for social work service delivery model and future research. The method is clinical data-mining audit of 100 sequentially sampled cases gathering quantitative demographic and service usage data. Descriptive analysis of file audit data raised interesting trends with potential to inform service delivery and usage; the key areas of the results included patient demographics, family involvement and impact, and child safety and risk issues. Transport accidents involving children often include other family members. Care planning must take into account psychosocial issues including patient and family emotional responses, availability of primary carers, and other practical needs that may impact on recovery and discharge planning. This study provides evidence to plan for further research and development of more integrated models of care.

Genome-based analysis of heme biosynthesis and uptake in prokaryotic systems.

Cavallaro, Gabriele; Decaria, Leonardo; Rosato, Antonio

Heme is the prosthetic group of many proteins that carry out a variety of key biological functions. In addition, for many pathogenic organisms, heme (acquired from the host) may constitute a very important source of iron. Organisms can meet their heme demands by taking it up from external sources, by producing the cofactor through a dedicated biosynthetic pathway, or both. Here we analyzed the distribution of proteins specifically involved in the processes of heme biosynthesis and heme uptake in 474 prokaryotic organisms. These data allowed us to identify which organisms are capable of performing none, one, or both processes, based on the similarity to known systems. Some specific instances where one or more proteins along the pathways had unusual modifications were singled out. For two key protein domains involved in heme uptake, we could build a series of structural models, which suggested possible alternative modes of heme binding. Future directions for experimental work are given.

The purpose was to increase job-specific knowledge about individual and work-related factors and their relationship with current and future work ability (WA). We studied cross-sectional relationships between mental demands, physical exertion during work, grip strength, musculoskeletal pain in the upper extremities and WA and the relationships between these variables and WA 11 years later. We used a dataset of a prospective cohort study (1997-2008) among employees of an engineering plant (n = 157). The cohort was surveyed by means of tests and written questions on work demands, musculoskeletal health, WA score (WAS; 0-10), and mental and physical WA. Spearman correlation coefficients and logistic regression analysis were used. Among manual workers, we found weak correlations between grip strength and current and future physical WA. We did not find predictors for future poor WA among the manual workers. Among the office workers, we found that musculoskeletal pain was moderately and negatively related to current WAS and physical WA. More handgrip strength related to better future WAS and physical WA. Musculoskeletal pain (OR 1.67 p < 0.01) and lower handgrip strength (OR 0.91 p < 0.05) predicted future poor WA among office workers. Our results showed cross-sectional and longitudinal relationships between musculoskeletal health and work ability depending on occupation. However, the present implies that predicting work ability in the far future based on health surveillance data is rather difficult. Testing the musculoskeletal system (grip strength) and asking workers' about their musculoskeletal health seems relevant when monitoring work ability.

Background: Burnout is a problem that impacts on the staff management costs and on the patient care quality. Objective: This work aimed to investigate some psychosocial factors related to burnout. Specifically, we explored the sample characteristics for moderate/high emotional exhaustion, cynicism and professional inefficacy, as well as the relationship between both working and environmental variables and burnout. Method: A cross-sectional study involving 307 nurses from one Italian hospital was carried out. A self-reported questionnaire was used to collect data. Data analysis was performed by using SPSS 19.0. Results: The results showed that there was a significant difference between nurses with low and moderate/high burnout in all the three components in almost all the examined organizational variables. In addition, we found that the aspects of working life had a significant impact on the three dimensions of burnout. Conclusions: The findings of this study not only can provide useful basis for future research in the field, but also can offer practical suggestions for improving nursing practice and promote effective workplace, thus reducing the risk burnout among nurses.

This grant is funded as a part of a program in which both research and educational impact are intended. Research work under this grant is directed at the understanding and use of future hyperspectral data such as that from imaging spectrometers. Specifically, the objectives of the work are (1) to prepare suitable means for analyzing data from sensors which have large numbers of spectral bands, (2) to advance the fundamental understanding of the manner in which soils and vegetative materials reflect high spectral resolution optical wavelength radiation, and (3) to maximize the impact of the results on the educational community. Over the life of the grant, the work has thus involved basic Earth science research and information system technique understanding and development in a mutually supportive way, however, more recently it has become necessary to focus the work primarily on areas (1) and (3). During the last year, the level of effort on this grant has been reduced to half its previous value. We have also been advised that this grant will end with the current year, thus this will be the penultimate semiannual progress summary.

The underlying purpose of this commentary and position paper is to achieve evidence-based recommendations on prevention of work-related musculoskeletal disorders (MSDs). Such prevention can take different forms (primary, secondary and tertiary), occur at different levels (i.e. in a clinical setting, at the workplace, at national level) and involve several types of activities. Members of the Scientific Committee (SC) on MSDs of the International Commission on Occupational Health (ICOH) and other interested scientists and members of the public recently discussed the scientific and clinical future of prevention of (work-related) MSDs during five round-table sessions at two ICOH conferences (in Cape Town, South Africa, in 2009, and in Angers, France, in 2010). Approximately 50 researchers participated in each of the sessions. More specifically, the sessions aimed to discuss new developments since 1996 in measures and classification systems used both in research and in practice, and agree on future needs in the field. The discussion focused on three questions: At what degree of severity does musculoskeletal ill health, and do health problems related to MSDs, in an individual worker or in a group of workers justify preventive action in occupational health? What reliable and valid instruments do we have in research to distinguish 'normal musculoskeletal symptoms' from 'serious musculoskeletal symptoms' in workers? What measures or classification system of musculoskeletal health will we need in the near future to address musculoskeletal health and related work ability? Four new, agreed-upon statements were extrapolated from the discussions: 1. Musculoskeletal discomfort that is at risk of worsening with work activities, and that affects work ability or quality of life, needs to be identified. 2. We need to know our options of actions before identifying workers at risk (providing evidence-based medicine and applying the principle of best practice). 3. Classification systems and measures must include aspects such as the severity, frequency, and intensity of pain, as well as measures of impairment of functioning, which can help in prevention, treatment and prognosis. 4. We need to be aware of economic and/or socio-cultural consequences of classification systems and measures.

In 1999 the General Assembly of the International Union of Pure and Applied Physics (IUPAP) voted to establish a Working Group on Women in Physics with the following charge: to survey the situation for women in physics in IUPAP member countries; to analyze and report the data collected along with suggestions on how to improve the situation; to suggest ways that women can become more involved in IUPAP, including the Liaison Committees, the Commissions, the Council, and the General Assemblies; and to report all findings at the next General Assembly in 2002. The Working Group was established in 2000 with 11 members representing North and South America, Europe, Asia and the Middle East/Africa. The Group has been gathering data on women in physics and is planning to hold an International Conference on Women in Physics at UNESCO Headquarters in Paris in March, 2002. I will discuss some of the findings and the plans for the future.

Work-related musculoskeletal disorders (WMSD) among construction workers remain high. Participatory ergonomics (PE) interventions that engage workers and employers in reducing work injury risks have shown mixed results. Eight-six workers from seven contractors participated in a PE program. A logic model guided the process evaluation and summative evaluation of short-term and intermediate impacts and long-term outcomes from surveys and field records. Process measures showed good delivery of training, high worker engagement, and low contractor participation. Workers' knowledge improved and workers reported changes to work practices and tools used; contractor provision of appropriate equipment was low (33%). No changes were seen in symptoms or reported physical effort. The PE program produced many worker-identified ergonomic solutions, but lacked needed support from contractors. Future interventions should engage higher levels of the construction organizational system to improve contractor involvement for reducing WMSD. Am. J. Ind.

DISMOL simulator was used to determine the best possible operating conditions to guide, in future studies, experimental works. This simulator needs several physical-chemical properties and often it is very difficult to determine them because of the complexity of the involved components. Their determinations must be made through correlations and/or predictions, in order to characterize the system and calculate it. The first try is to have simulation results of a system that later can be validated with experimental data. To implement, in the simulator, the necessary parameters of complex systems is a difficult task. In this work, we aimed to determe these properties in order to evaluate the tocopherol (vitamin E) recovery using a DISMOL simulator. The raw material used was the crude deodorizer distillate of soya oil. With this procedure, it is possible to determine the best operating conditions for experimental works and to evaluate the process in the separation of new systems, analyzing the profiles obtained from these simulations for the falling film molecular distillator.

Consultant-based otolaryngology emergency service: a five-year experience.

PubMed

Barnes, M L; Hussain, S S M

2011-12-01

To present our experience of running a consultant-based otolaryngology emergency care service for more than five years. In 2003, we developed a system of consultant-based emergency service: consultants spent a week on-call providing a dedicated emergency service, with routine commitments cancelled. Our new system had advantages over traditional working practices in terms of consultant involvement, trainee education, continuity and efficiency. It also reduced disruption to elective commitments for both consultants and registrars. This system was fundamental to the successful review of all urgent (and in future elective) cases within target periods. Only 31 per cent of new referrals to the consultant emergency clinics required a further appointment. Good teamwork and flexibility in working arrangements have been essential to the success of this service. Given that health service changes have reduced junior trainee working hours and numbers, and that patients increasingly expect to be treated by trained doctors, our new consultant-based emergency service has merit. Although implementation in other units may differ, we recommend this new service, for the above reasons.

Dare to be different: transformational leadership may hold the key to reducing the nursing shortage.

PubMed

Thyer, Genevieve L

2003-03-01

Health care leadership continues to run under a transactional style that may be causing nurses to leave the system. Nurses no longer wish to stay in the profession perhaps because they struggle ideologically with the system in which they work. However, nurses may hold the key to transforming health care and dragging it into the 21st century in terms of work practices and reform. This is because nurses are visionary, creative, involved in decision making at patient level and have gender based qualities, and communication strategies that the health care sector needs. In contrast to transaction leadership, transformational leadership and team development has a positive affect on communication and team building. The later style is ideologically suited to nurses and may ensure the future of nurses and nursing in the health care sector. The case study described in this paper was an actual working environment and one that I came across all too often as a registered nurse and clinical educator.

In Australia, since 2009, the Consumer and Community Involvement Program (formerly the Consumer and Community Participation Program) has developed and run workshops to help people working in health and medical research involve more consumers (patients) and community members (the public) in their research. In 2012, workshop attendees were invited to do an online survey to find out the effect, if any, that attending a workshop had on their awareness of and attitudes to consumer and community involvement. They were also asked about changes in their behaviour when it came to the involvement of consumers and the community in their work. The study found that, for people who answered the survey, more than double the number found consumer and community involvement very relevant after attending a workshop, compared with the number who thought that before attending one. Also, amongst those who answered the survey, 94 % thought that the workshop increased their understanding about involvement. Background There is limited evidence of the benefits of providing training workshops for researchers on how to involve consumers (patients) and the community (public) in health and medical research. Australian training workshops were evaluated to contribute to the evidence base. The key objective was to evaluate the impact of the workshops in increasing awareness of consumer and community involvement; changing attitudes to future implementation of involvement activities and influencing behaviour in the methods of involvement used. A secondary objective was to use a formal evaluation survey to build on the anecdotal feedback received from researchers about changes in awareness, attitudes and behaviours. Methods The study used a cross-sectional, online survey of researchers, students, clinicians, administrators and members of non-government organisations who attended Consumer and Community Involvement Program training workshops between 2009 and 2012 to ascertain changes to awareness, attitudes and behaviours related to consumer and community involvement in health and medical research. Results Changes in awareness and attitudes were demonstrated by more than double the number of respondents finding involvement very relevant after attending a workshop compared with those who did so before attending; 94 % of respondents agreed that the workshops increased their understanding of how involvement can add value to research. Conclusions The training workshops raised awareness and increased relevance of consumer and community involvement among Australian researchers who attended a workshop and responded to the survey. The results of the survey are also suggestive that the training led to behaviour changes through increased consumer and community involvement.

Cultural competency training has been proposed as a way to improve patient outcomes. There is a need for evidence showing that these interventions reduce health disparities. The objective was to conduct a systematic review addressing the effects of cultural competency training on patient-centered outcomes; assess quality of studies and strength of effect; and propose a framework for future research. The authors performed electronic searches in the MEDLINE/PubMed, ERIC, PsycINFO, CINAHL and Web of Science databases for original articles published in English between 1990 and 2010, and a bibliographic hand search. Studies that reported cultural competence educational interventions for health professionals and measured impact on patients and/or health care utilization as primary or secondary outcomes were included. Four authors independently rated studies for quality using validated criteria and assessed the training effect on patient outcomes. Due to study heterogeneity, data were not pooled; instead, qualitative synthesis and analysis were conducted. Seven studies met inclusion criteria. Three involved physicians, two involved mental health professionals and two involved multiple health professionals and students. Two were quasi-randomized, two were cluster randomized, and three were pre/post field studies. Study quality was low to moderate with none of high quality; most studies did not adequately control for potentially confounding variables. Effect size ranged from no effect to moderately beneficial (unable to assess in two studies). Three studies reported positive (beneficial) effects; none demonstrated a negative (harmful) effect. There is limited research showing a positive relationship between cultural competency training and improved patient outcomes, but there remains a paucity of high quality research. Future work should address challenges limiting quality. We propose an algorithm to guide educators in designing and evaluating curricula, to rigorously demonstrate the impact on patient outcomes and health disparities.

Using future thinking to reduce temporal discounting: Under what circumstances are the medial temporal lobes critical?

The capacity to envision the future plays an important role in many aspects of cognition, including our ability to make optimal, adaptive choices. Past work has shown that the medial temporal lobe (MTL) is necessary for decisions that draw on episodic future thinking. By contrast, little is known about the role of the MTL in decisions that draw on semantic future thinking. Accordingly, the present study investigated whether the MTL contributes to one form of decision making, namely intertemporal choice, when such decisions depend on semantic consideration of the future. In an intertemporal choice task, participants must select either a smaller amount of money that is available in the present or a larger amount of money that would be available at a future date. Amnesic individuals with MTL damage and healthy control participants performed such a task in which, prior to making a choice, they engaged in a semantic generation exercise, wherein they generated items that they would purchase with the future reward. In experiment 1, we found that, relative to a baseline condition involving standard intertemporal choice, healthy individuals were more inclined to select a larger, later reward over a smaller, present reward after engaging in semantic future thinking. By contrast, amnesic participants were paradoxically less inclined to wait for a future reward following semantic future thinking. This finding suggests that amnesics may have had difficulty "tagging" the generated item(s) as belonging to the future. Critically, experiment 2 showed that when the generated items were presented alongside the intertemporal choices, both controls and amnesic participants shifted to more patient choices. These findings suggest that the MTL is not needed for making optimal decisions that draw on semantic future thinking as long as scaffolding is provided to support accurate time tagging. Together, these findings stand to better clarify the role of the MTL in decision making. Published by Elsevier Ltd.

Recent studies suggest that a brain network mainly associated with episodic memory has a more general function in imagining oneself in another time, place or perspective (e.g. episodic future thought, theory of mind, default mode). If this is true, counterfactual thinking (e.g. ‘If I had left the office earlier, I wouldn’t have missed my train.’) should also activate this network. Present functional magnetic resonance imaging (fMRI) study explores the common and distinct neural activity of counterfactual and episodic thinking by directly comparing the imagining of upward counterfactuals (creating better outcomes for negative past events) with the re-experiencing of negative past events and the imagining of positive future events. Results confirm that episodic and counterfactual thinking share a common brain network, involving a core memory network (hippocampal area, temporal lobes, midline, and lateral parietal lobes) and prefrontal areas that might be related to mentalizing (medial prefrontal cortex) and performance monitoring (right prefrontal cortex). In contrast to episodic past and future thinking, counterfactual thinking recruits some of these areas more strongly and extensively, and additionally activates the bilateral inferior parietal lobe and posterior medial frontal cortex. We discuss these findings in view of recent fMRI evidence on the working of episodic memory and theory of mind. PMID:22403155

A core construct in the lifespan theory of socioemotional selectivity, future time perspective (FTP) refers to individuals' perceptions of their remaining time in life. Its adaptation to the work context, occupational future time perspective (OFTP), entails workers' perceptions of remaining time and opportunities in their careers. Over the past decade, several quantitative studies have investigated antecedents and consequences of general FTP and OFTP in the work context (i.e., FTP at work). We systematically review and critically discuss this literature on general FTP ( k = 17 studies) and OFTP ( k = 16 studies) and highlight implications for future research and practice. Results of our systematic review show that, in addition to its strong negative relationship with age, FTP at work is also associated with other individual (e.g., personality traits) and contextual variables (e.g., job characteristics). Moreover, FTP at work has been shown to mediate and moderate relationships of individual and contextual antecedents with occupational well-being, as well as motivational and behavioral outcomes. As a whole, findings suggest that FTP at work is an important variable in the field of work and aging, and that future research should improve the ways in which FTP at work is measured and results on FTP at work are reported.

2018-01-01

Sex work is assumed to have a negative effect on self-esteem, nearly exclusively expressed as low self-worth, due to its social unacceptability and despite the diversity of persons, positions and roles within the sex industry. In this study, we asked a heterogeneous sample of 218 Canadian sex workers delivering services in various venues about how their work affected their sense of self. Using thematic analysis based on a three-dimensional conception of self-esteem - self-worth (viewing oneself in a favourable light), authenticity (being one's true self) and self-efficacy (competency) - we shed light on the relationship between involvement in sex work and self-esteem. Findings demonstrate that the relationship between sex work and self-esteem is complex: the majority of participants discussed multiple dimensions of self-esteem and often spoke of how sex work had both positive and negative effects on their sense of self. Social background factors, work location and life events and experiences also had an effect on self-esteem. Future research should take a more complex approach to understanding these issues by considering elements beyond self-worth, such as authenticity and self-efficacy, and examining how sex workers' backgrounds and individual motivations intersect with these three dimensions.

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

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.

Applying theories to better understand socio-political challenges in implementing evidence-based work disability prevention strategies.

PubMed

Ståhl, Christian; Costa-Black, Katia; Loisel, Patrick

2018-04-01

This article explores and applies theories for analyzing socio-political aspects of implementation of work disability prevention (WDP) strategies. For the analysis, theories from political science are explained and discussed in relation to case examples from three jurisdictions (Sweden, Brazil and Québec). Implementation of WDP strategies may be studied through a conceptual framework that targets: (1) the institutional system in which policy-makers and other stakeholders reside; (2) the ambiguity and conflicts regarding what to do and how to do it; (3) the bounded rationality, path dependency and social systems of different stakeholders; and (4) coalitions formed by different stakeholders and power relations between them. In the case examples, the design of social insurance systems, the access to and infrastructure of healthcare systems, labor market policies, employers' level of responsibility, the regulatory environment, and the general knowledge of WDP issues among stakeholders played different roles in the implementation of policies based on scientific evidence. Future research may involve participatory approaches focusing on building coalitions and communities of practice with policy-makers and stakeholders, in order to build trust, facilitate cooperation, and to better promote evidence utilization. Implications for Rehabilitation Implementation of work disability prevention policies are subject to contextual influences from the socio-political setting and from relationships between stakeholders Stakeholders involved in implementing strategies are bound to act based on their interests and previous courses of action To promote research uptake on the policy level, stakeholders and researchers need to engage in collaboration and translational activities Political stakeholders at the government and community levels need to be more directly involved as partners in the production and utilization of evidence.

Patient and public involvement (PPI) is increasingly recognised as important in research. Most PPI takes place face-to-face, but this can be difficult for people who are unwell or have caring responsibilities. As these challenges are particularly common in palliative care and rehabilitation research, we developed an online forum for PPI: www.csipublicinvolvement.co.uk. In this study, we explored how well the online forum worked, if it is a suitable method for PPI, and how PPI members and researchers reacted to using it. We used an existing theory about online interventions to help choose the 'right' questions to ask participants. We invited PPI members and researchers who had used the online forum to participate in focus groups, and identified the most important themes discussed. Within this study, PPI members have helped with the interview questions, analysis, and write up. Overall, four PPI members and five researchers participated in the focus groups. Participants felt the online forum worked well and had multiple benefits. From the discussions, we identified four key questions to consider when developing online methods for PPI: how does the forum work, how does it engage people, how does it empower people, and what is the impact? Participants suggested the forum could be improved by being more PPI and less researcher focused. We conclude that when developing online methods of PPI, a functioning forum is not enough: it also needs to be engaging and empowering to have an impact. Future work can use these four domains when developing their own online PPI methods. Patient and public involvement (PPI) in research is increasingly recognised as important. Most PPI activities take place face-to-face, yet this can be difficult for people with ill health or caring responsibilities, and may exclude people from hard-to-reach populations (e.g. living in vulnerable social circumstances and/or remote geographical locations). These challenges are particularly pertinent in palliative care and rehabilitation research where people often live with, or care for someone with, advanced illness. In response to this, we aimed to test the functionality, feasibility, and acceptability of an online forum for PPI for palliative care and rehabilitation research (www.csipublicinvolvement.co.uk). We conducted separate focus groups with PPI members and researchers who had used the online forum. Data collection was underpinned by DeLone and Mclean's model of information systems success. Focus groups were recorded, transcribed, and analysed using inductive thematic analysis. Dual coding by two authors ensured rigour, and attention was paid to divergent cases. Four PPI members and five researchers participated in the focus groups (two PPI focus groups, one researcher focus group). The online forum was perceived as functional, feasible, and acceptable. Our analysis identified four key questions to consider when developing online methods for PPI: (1) how does the forum work, (2) how does it engage people, (3) how does it empower people, and (4) what is the impact? PPI members felt that the online forum was too researcher led, and needed to be more PPI focussed. When developing online methods of PPI, a functioning forum is not enough: it also needs to be engaging and empowering to have an impact. To optimise online involvement, future work should refer to these four domains and balance the needs of researchers and PPI members.

This study was designed to examine the associations of biological father and social father involvement during childhood with African American young men's development and engagement in risk behaviors. With a sample of 505 young men living in the rural South of the United States, a dual mediation model was tested in which retrospective reports of involvement from biological fathers and social fathers were linked to young men's substance misuse and multiple sexual partnerships through men's relational schemas and future expectations. Results from structural equation modeling indicated that levels of involvement from biological fathers and social fathers predicted young men's relational schemas; only biological fathers' involvement predicted future expectations. In turn, future expectations predicted levels of substance misuse, and negative relational schemas predicted multiple sexual partnerships. Biological fathers' involvement evinced significant indirect associations with young men's substance misuse and multiple sexual partnerships through both schemas and expectations; social fathers' involvement exhibited an indirect association with multiple sexual partnerships through relational schemas. Findings highlight the unique influences of biological fathers and social fathers on multiple domains of African American young men's psychosocial development that subsequently render young men more or less likely to engage in risk behaviors.

On the Development and Application of High Data Rate Architecture (HiDRA) in Future Space Networks

NASA Technical Reports Server (NTRS)

Hylton, Alan; Raible, Daniel; Clark, Gilbert

2017-01-01

Historically, space missions have been severely constrained by their ability to downlink the data they have collected. These constraints are a result of relatively low link rates on the spacecraft as well as limitations on the time during which data can be sent. As part of a coherent strategy to address existing limitations and get more data to the ground more quickly, the Space Communications and Navigation (SCaN) program has been developing an architecture for a future solar system Internet. The High Data Rate Architecture (HiDRA) project is designed to fit into such a future SCaN network. HiDRA's goal is to describe a general packet-based networking capability which can be used to provide assets with efficient networking capabilities while simultaneously reducing the capital costs and operational costs of developing and flying future space systems.Along these lines, this paper begins by reviewing various characteristics of modern satellite design as well as relevant characteristics of emerging technologies (such as free-space optical links capable of working at 100+ Gbps). Next, the paper describes HiDRA's design, and how the system is able to both integrate and support the operation of not only today's high-rate systems, but also the high-rate systems likely to be found in the future. This section also explores both existing and future networking technologies, such as Delay Tolerant Networking (DTN) protocol (RFC4838 citeRFC:1, RFC5050citeRFC:2), and explains how HiDRA supports them. Additionally, this section explores how HiDRA is used for scheduling data movement through both proactive and reactive link management. After this, the paper moves on to explore a reference implementation of HiDRA. This implementation is currently being realized based on a Field Programmable Gate Array (FPGA) memory and interface controller that is itself controlled by a local computer running DTN software. Next, this paper explores HiDRA's natural evolution, which includes an integration path for software-defined networking (SDN) switches. This section also describes considerations for both near-Earth and deep-space instantiations of HiDRA, describing how differences in latencies between the environments will necessarily influence how the system is configured and the networks operate. Finally, this paper describes future work. This section includes a description of a potential ISS implementation which will allow rapid advancement through the technology readiness levels (TRL). This section also explores work being done to support HiDRA's successful implementation and operation in a heterogeneous network: such a network could include communications equipment spanning many vintages and capabilities, and one significant aspect of HiDRA's future development involves balancing compatibility with capability.

Work with men to end violence against women: a critical stocktake

This paper provides a critical assessment of efforts to involve men in the prevention of men's violence against women. Although there is a substantial evidence base attesting to the effectiveness of at least some strategies and interventions, this field is also limited in important ways. Violence prevention efforts often have focused on changing men's attitudes, rather than also seeking to transform structural and institutional inequalities. While feminist and queer scholarship has explored diversities and pluralities in the organisation of sexuality, much violence prevention work often assumes a homogenously heterosexual male constituency. Too often this work is conceptually simplistic with regard to gender. Against this background, this paper contests and complicates several assumptions that are part of an emerging consensus in men's violence prevention: first, that it is in men's interests to support progress towards non-violence and gender equality; second, that the best people to engage and work with men are other men; and finally, the strengths and limitations of inviting and drawing on ‘real men’. A critical assessment of the field's working assumptions is vital if it is to contribute to the future prevention of men's violence against women. PMID:26414870

Prolonged sitting time has been identified as a health risk factor. Sit-stand workstations allow desk workers to alternate between sitting and standing throughout the working day, but not much is known about their acceptability and feasibility. Hence, the aim of this study was to qualitatively evaluate the acceptability, feasibility and perceptions of using sit-stand workstations in a group of desk-based office workers. This article describes the qualitative evaluation of the randomized controlled cross-over Stand@Work pilot trial. Participants were adult employees recruited from a non-government health agency in Sydney, Australia. The intervention involved using an Ergotron Workfit S sit-stand workstation for four weeks. After the four week intervention, participants shared their perceptions and experiences of using the sit-stand workstation in focus group interviews with 4-5 participants. Topics covered in the focus groups included patterns of workstation use, barriers and facilitators to standing while working, effects on work performance, physical impacts, and feasibility in the office. Focus group field notes and transcripts were analysed in an iterative process during and after the data collection period to identify the main concepts and themes. During nine 45-min focus groups, a total of 42 participants were interviewed. Participants were largely intrinsically motivated to try the sit-stand workstation, mostly because of curiosity to try something new, interest in potential health benefits, and the relevance to the participant's own and organisation's work. Most participants used the sit-stand workstation and three common usage patterns were identified: task-based routine, time-based routine, and no particular routine. Common barriers to sit-stand workstation use were working in an open plan office, and issues with sit-stand workstation design. Common facilitators of sit-stand workstation use were a supportive work environment conducive to standing, perceived physical health benefits, and perceived work benefits. When prompted, most participants indicated they were interested in using a sit-stand workstation in the future. The use of a sit-stand workstation in this group of desk-based office workers was generally perceived as acceptable and feasible. Future studies are needed to explore this in different desk-based work populations and settings.

The work performed under this grant has led to the development of a detection system that will be used to measure reaction rates for proton or neutron capture reactions at stellar energies on radioactive ions far from stability. The reaction rates are needed to better understand the physics of nucleosynthesis in explosive stellar processes such as supernovae and x-ray burst events. The radioactive ions will be produced at the Radioactive Ion Beam Facility (RIBF) at RIKEN near Tokyo, Japan. During the course of this work, the group involved in this project has expanded by several institutions in Europe and Japanmore » and now involves collaborators from the U.S., Japan, Hungary, Romania, Germany, Spain, Italy, China, and South Korea. As part of the project, a novel design based on large-area silicon detectors has been built and tested and the performance characterized in a series of tests using particle beams with a variety of atomic numbers at the Cyclotron Institute of Texas A&M University and the Heavy Ion Medical Accelerator in Chiba facility (HIMAC) in Chiba, Japan. The work has involved mechanical construction of a special purpose vacuum chamber, with a precision mounting system for the silicon detectors, development of a new ASICs readout system that has applications with a wide variety of silicon detector systems, and the development of a data acquisition system that is integrated into the computer system being used at RIBF. The parts noted above that are needed to carry out the research program are completed and ready for installation. Several approved experiments that will use this system will be carried out in the near future. The experimental work has been delayed due to a large increase in the cost and availability of electrical power for RIBF that occurred following the massive earthquake and tsunami that hit Japan in the spring of 2011. Another component of the research carried out with this grant involved developing the theoretical tools that are required to extract the information from the experiments that is needed to determine the stellar reaction rates. The tools developed through this part of the work will be made freely available for general use.« less

Field design changed substantially from extended-field RT (EF-RT) to involved-field RT (IF-RT) and now to involved-node RT (IN-RT) and involved-site RT (IS-RT) as well as treatment techniques in radiotherapy (RT) of Hodgkin's lymphoma (HL). The purpose of this article is to demonstrate the establishment of a quality assurance program (QAP) including modern RT techniques and field designs within the German Hodgkin Study Group (GHSG). In the era of modern conformal RT, this QAP had to be fundamentally adapted and a new evaluation process has been intensively discussed by the radiotherapeutic expert panel of the GHSG. The expert panel developed guidelines and criteria to analyse "modern" field designs and treatment techniques. This work is based on a dataset of 11 patients treated within the sixth study generation (HD16-17). To develop a QAP of "modern RT", the expert panel defined criteria for analysing current RT procedures. The consensus of a modified QAP in ongoing and future trials is presented. With this schedule, the QAP of the GHSG could serve as a model for other study groups.

Concern has been expressed recently regarding the need to enhance the performance of individuals with highly significant disabilities in community-based, supported jobs. We evaluated a shared-work program for reducing job coach assistance provided to three workers with severe multiple disabilities in a publishing company. Following systematic observations of the assistance provided as each worker worked on entire job tasks, steps comprising the tasks were then re-assigned across workers. The re-assignment involved assigning each worker only those task steps for which the respective worker received the least amount of assistance (e.g., re-assigning steps that a worker could not complete due to physical disabilities), and ensuring the entire tasks were still completed by combining steps performed by all three workers. The shared-work program was accompanied by reductions in job coach assistance provided to each worker. Work productivity of the supported workers initially decreased but then increased to a level equivalent to the higher ranges of baseline productivity. These results suggested that the shared-work program appears to represent a viable means of enhancing supported work performance of people with severe multiple disabilities in some types of community jobs. Future research needs discussed focus on evaluating shared-work approaches with other jobs, and developing additional community work models specifically for people with highly significant disabilities.

Psychosocial risk and protective factors for the health and well-being of professionals working in emergency and non-emergency medical transport services, identified via questionnaires.

Medical transport (MT) professionals are subject to considerable emotional demands due to their involvement in life-or-death situations and their exposure to the serious health problems of their clients. An increase in the demand for MT services has, in turn, increased interest in the study of the psychosocial risk factors affecting the health of workers in this sector. However, research thus far has not distinguished between emergency (EMT) and non-emergency (non-EMT) services, nor between the sexes. Furthermore, little emphasis has been placed on the protective factors involved. The main objective of the present study is to identify any existing differential exposure - for reasons of work setting (EMT and non-EMT) or of gender - to the various psychosocial risk and protective factors affecting the health of MT workers. Descriptive and transversal research with responses from 201 professionals. The scores obtained on the various psychosocial scales in our study - as indicators of future health problems - were more unfavourable for non-EMT workers than they were for EMT workers. Work setting, but not gender, was able to account for these differences. The scores obtained for the different psychosocial factors are generally more favourable for the professionals we surveyed than those obtained in previous samples. The significant differences observed between EMT and non-EMT personnel raise important questions regarding the organization of work in companies that carry out both services at the same time in the same territory. The relationships among the set of risk/protective factors suggests a need for further investigation into working conditions as well as a consideration of the workers' sense of coherence and subjective well-being as protective factors against occupational burnout syndrome.

Dentistry students and dentists comprise a unique group of professionals, whose everyday professional activity requires long hours of standing and working in a position considered unhealthy for the lower back and neck. Our aim was to explore the factors involved in the appearance of low back and neck pain in dentistry students as well as the impact of the pain on the students' professional and everyday activities. A questionnaire was given to all dentistry students of the 4th and 5th year of our university. The questionnaire included 43 questions regarding demographic data, history (spinal injury, other comorbidities), daily activities (exercise, smoking, alcohol and caffeine consumption, use of cell phone), professional activities (length and type of dental work), pattern and intensity of pain, and personal pain evaluation. A statistical analysis of the gathered data was performed. All students having suffered a spinal trauma or indicating any other comorbidity that could cause severe pain of the spine were excluded from the study. Fifty-five students (21 male, 34 female) were included. Our data showed that increased alcohol consumption and prolonged use of cell phone were connected to increased levels of pain. The students reported that the most frequent onset of pain was 1 h after starting to work in a standing position, while the majority believed that their working habits were involved in the appearance and the intensity of neck and low-back pain. Our findings indicate that among dentistry students appears to be a causative relationship between their professional activities and the experienced spinal pain. These findings may be useful in a possible future restructuring of the educational program in dental schools, as well as in improving the ergonomics of dentistry working units.

Background Acute traumatic tendon injuries of the hand and wrist are commonly encountered in the emergency department. Despite the frequency, few studies have examined the true incidence of acute traumatic tendon injuries in the hand and wrist or compared the incidences of both extensor and flexor tendon injuries. Methods We performed a retrospective population-based cohort study of all acute traumatic tendon injuries of the hand and wrist in a mixed urban and rural Midwest county in the United States between 2001-2010. A regional epidemiologic database and medical codes were used to identify index cases. Epidemiologic information including occupation, year of injury, mechanism of injury and the injured tendon and zone were recorded. Results During the 10-year study period there was an incidence rate of 33.2 injuries per 100,000 person-years. There was a decreasing rate of injury during the study period. Highest incidence of injury occurred at 20-29 years of age. There was significant association between injury rate and age, and males had a higher incidence than females. The majority of cases involved a single tendon, with extensor tendon injuries occurring more frequently than flexor tendons. Typically, extensor tendon injuries involved zone three of the index finger, while flexor tendons involved zone two of the index finger. Work-related injuries accounted for 24.9% of acute traumatic tendon injuries. The occupations of work-related injuries were assigned to major groups defined by the 2010 Standard Occupational Classification structure. After assigning these patients' occupations to respective major groups, the most common groups work-related injuries occurred in construction and extraction occupations (44.2%), food preparation and serving related occupations (14.4%), and transportation and material moving occupations (12.5%). Conclusions Epidemiology data enhances our knowledge of injury patterns and may play a role in the prevention and treatment of future injuries, with an end result of reducing lost work time and economic burden.

Introduction Despite the expected beneficial effects on quality of care, patient involvement in diabetes care groups, which deliver a bundled paid integrated care programme for diabetes type 2, seems to be limited. The aim of this study was to gain insight into levels and methods of patient involvement, into facilitators and barriers, and into the future preferences of care groups and patient representatives. Theory and methods Semi-structured interviews were held with 10 representatives of care groups and 11 representatives of patient advocacy groups. An adapted version of Arnstein's ladder of citizen participation was used to define five levels of patient involvement. Results Patient involvement in care groups was mostly limited to informing and consulting patients. Higher levels, i.e., advising, co-producing and decision-making, were less frequently observed. Care groups and patient representatives perceived largely the same barriers and facilitators and had similar preferences regarding future themes and design of patient involvement. Conclusion Constructive collaboration between diabetes care groups and patient representatives to enhance patient involvement in the future seems viable. Several issues such as the lack of evidence for effectiveness of patient involvement, differences in viewpoints on the role and responsibilities of care groups and perceived barriers need to be addressed.

Disability pension and everyday life: a period of transition and subjective aspects of future occupational life.

PubMed

Johansson, Annica E M; Johansson, Ulla

2011-01-01

The purpose was to explore and describe the everyday life experiences among people with a disability pension and their expectations for future occupational life. A purposeful sample of 14 men and women were interviewed. Of these, ten people received full-time disability pension and four people were on partial disability pension while working part time. A content analysis approach revealed three themes: strategies for handling a changed life situation, adaptations to remaining functional capacity, and expectations on future occupational life. Initially, leaving the work market entailed a period of emotional discomfort. To help handle this discomfort, structures for participation and performance came to signify a balanced everyday life. The central conclusion drawn is that the informants with full-time disability pension reconciled themselves to their situation, changing their conception of what life on a disability pension means, while those informants who worked part-time saw their future role as that of worker. Thus, being employed constitutes one factor that promotes a future work career. Another factor related to work capacity is the need for balance between paid work and domestic work reported by disability pensioners working part-time. This area could serve as a point of departure for work rehabilitation.

Integrating computation into the undergraduate curriculum: A vision and guidelines for future developments

NASA Astrophysics Data System (ADS)

Chonacky, Norman; Winch, David

2008-04-01

There is substantial evidence of a need to make computation an integral part of the undergraduate physics curriculum. This need is consistent with data from surveys in both the academy and the workplace, and has been reinforced by two years of exploratory efforts by a group of physics faculty for whom computation is a special interest. We have examined past and current efforts at reform and a variety of strategic, organizational, and institutional issues involved in any attempt to broadly transform existing practice. We propose a set of guidelines for development based on this past work and discuss our vision of computationally integrated physics.

ABSTRACT The use of nanocarriers as drug delivery systems for therapeutic or imaging agents can improve the pharmacological properties of commonly used compounds in cancer diagnosis and treatment. Advances in the surface engineering of nanoparticles to accommodate targeting ligands turned nanocarriers attractive candidates for future work involving targeted drug delivery. Although not targeted, several nanocarriers have been approved for clinical use and they are currently used to treat and/or diagnosis various types of cancers. Furthermore, there are several formulations, which are now in various stages of clinical trials. This review examined some approved formulations and discussed the advantages of using nanocarriers in cancer therapy. PMID:27074238

Effective management of complex coastal ecosystems necessitates access to scientific knowledge that can be acquired through a multidisciplinary approach involving Federal and State scientists that take advantage of agency expertise and resources for the benefit of all participants working toward a set of common research and management goals. Cooperative geostatic investigations have led toward building databases of fundamental scientific knowledge that can be utilized to manage coastal Alabama's natural and future development. These databases have been used to assess the occurrence and economic potential of hard mineral resources in the Alabama EFZ, and to support oil spill contingency planning and environmental analysis for coastal Alabama.

Materials science. Modeling strain hardening the hard way.

PubMed

Gumbsch, Peter

2003-09-26

The plastic deformation of metals results in strain hardening, that is, an increase in the stress with increasing strain. Materials engineers can provide a simple approximate description of such deformation and hardening behavior. In his perspective, Gumbsch discusses work by Madec et al. who have undertaken the formidable task of computing the physical basis for the development of strain hardening by individually following the fate of all the dislocations involved. Their simulations show that the collinear dislocation interaction makes a substantial contribution to strain hardening. It is likely that such simulations will play an important role in guiding the development of future engineering descriptions of deformation and hardening.

The purpose of the study is to analyze the dynamics of global gene expression changes in the lung tissue of rats exposed to lunar dust particles. Multiple pathways and transcription factors were identified using the Ingenuity Pathway Analysis tool, showing the potential networks of these signaling regulations involved in lunar dust-induced prolonged proflammatory response and toxicity. The data presented in this study, for the first time, explores the molecular mechanisms of lunar dust induced toxicity. This work contributes not only to the risk assessment for future space exploration, but also to the understanding of the dust-induced toxicity to humans on earth.

2014-01-01

This article adds to a small, but growing, body of work on trans sexualities and partnerships, and provides a much-needed inquiry into the complex and contested politics of desire when we take trans identities, bodies, and sexualities into account. Using digital ethnographic data from YouTube videos along with in-person observational data from LGBTQ and trans conferences in the U.S., Tompkins argues that a sex-positive trans politics cannot emerge in trans and trans-allied communities if the rhetoric of the "tranny chaser" continues to inform discourses of desire and attraction to trans people.

Heart failure (HF) afflicts nearly 6 million Americans, resulting in 1 million emergency department (ED) visits and over 1 million annual hospital discharges. The majority of inpatient admissions originate in the ED; thus, it is crucial that emergency physicians and other providers involved in early management understand the latest developments in diagnostic testing, therapeutics, and alternatives to hospitalization. This article discusses contemporary ED management as well as the necessary next steps for ED-based acute HF research. © 2015 by the Society for Academic Emergency Medicine.

STAR*D: helping to close the gap between science and practice.

Shern, David L; Moran, Hazel

2009-11-01

Practical clinical trials, such as STAR*D (Sequenced Treatment Alternatives to Relieve Depression), extend the traditional randomized controlled trial to real-world settings. Consumers and clinicians should be encouraged by STAR*D's 70% remission rate and should realize that for many participants remission required medication switching and augmentation. Policy makers should recognize the importance of easy access to a full range of treatments. Researchers should be sobered by the high attrition rate and the 30% of participants who did not achieve remission. Although more such practical trials are needed, future work must more meaningfully involve consumers in design, analysis, and interpretation.

Man and machine design for space flight

Louviere, A. J.

1979-01-01

The factors involved in creating effective designs for living and working in a weightless environment are discussed. Among the areas covered are special provisions for eating and drinking, a special shower nozzle to remove soap, electric shavers designed for vacuum containment of the clippings, and the need for restraint systems at the crew's workstations. Attention is given to the fact that the crewmen assume a neutral body posture in weightlessness which is an important consideration in designing displays, controls, and windows. It is concluded that the incorporation of the change in body posture and the requirement for restraint into future designs will greatly facilitate the crewman's task in the weightless environment.

Burns, Joseph A

2010-07-29

For 350 years after Galileo's discoveries, ground-based telescopes and theoretical modelling furnished everything we knew about the Sun's planetary retinue. Over the past five decades, however, spacecraft visits to many targets transformed these early notions, revealing the diversity of Solar System bodies and displaying active planetary processes at work. Violent events have punctuated the histories of many planets and satellites, changing them substantially since their birth. Contemporary knowledge has finally allowed testable models of the Solar System's origin to be developed and potential abodes for extraterrestrial life to be explored. Future planetary research should involve focused studies of selected targets, including exoplanets.

Layland, J. W.

1974-01-01

An approximate analysis of the effect of a noisy carrier reference on the performance of sequential decoding is presented. The analysis uses previously developed techniques for evaluating noisy reference performance for medium-rate uncoded communications adapted to sequential decoding for data rates of 8 to 2048 bits/s. In estimating the ten to the minus fourth power deletion probability thresholds for Helios, the model agrees with experimental data to within the experimental tolerances. The computational problem involved in sequential decoding, carrier loop effects, the main characteristics of the medium-rate model, modeled decoding performance, and perspectives on future work are discussed.

This study aimed to identify social, economic, structural, and individual-level vulnerabilities of female adolescents who sell sex in Kumasi, Ghana. Twenty-four in-depth interviews and 4 focus group discussions were conducted with female sex workers of age 18-20 years who had been involved in sex work for at least 2 years. Total sample size was 48. One-third of participants started sex work before age 15. Knowledge of HIV was accurate and most reported having intentions to use condoms consistently with clients; however, factors such as higher payments, drug and/or alcohol use, fear of violence, and police harassment affected condom use. They perceived violence and rape at the hands of clients as their greatest risk. They also reported abuse and exploitation by police. Respondents voiced strong concerns that girls and teens involved in sex work are at higher risk of unsafe sex, exploitation, and abuse than their older and more experienced counterparts. Unprotected sex with boyfriends was also common. The pathway to sex work followed a similar pattern for many study participants who left their rural homes for Kumasi in search of economic opportunity. While adolescents who sell sex appear to be abundant in Kumasi, they have been missed by HIV prevention and harm reduction programming. The findings from this study informed the design and implementation of a young female sex worker peer educator pilot program. Key elements of that program are presented, and recommendations for future program evaluation are made.

Background The phases of career building today bring out a more complex process than in previous decades. Starting from the literature review, the university-to-work transition is considered a very important step in the future career of the graduates, and it involves some psychological resources and requires specific abilities. Methods Research has examined the psychological resources that students at the end of a degree course can use in the university-to-work transition. The aim of the study is to verify the relationship between academic satisfaction and career identity, and the mediational role of readiness and confidence on this relationship. A group of 438 students were assigned to complete a questionnaire in order to examine the relationship between academic satisfaction and career identity and the role of core components of psychological resources: readiness and confidence as mediator. Results The results indicated both a direct relationship between academic satisfaction and career identity and a mediated relationship with the influence of readiness and confidence for a transition. Adding to our results, we assert that academic satisfaction has a directed effect on confidence during the transition and is a predictor of career identity, both directly and by the mediation of readiness in career transitions. Conclusion Career identity has implication for exploratory behavior, thus increasing the motivation and mindfulness that create a virtuous circle, influencing the development of knowledge and skills, which are the base of proactivity and confidence in construction of one’s future career.

2018-02-21

We conducted a pilot project assessing the perceived utility and relevance of wellbeing sessions provided to interns at a large regional teaching hospital in Australia with the aim of promoting intern wellbeing and fostering a nurturing and supportive learning and work hospital culture. Our intervention involved two separate 60 minute lectures covering wellbeing topics and skills, to approximately 50 interns within protected teaching time, along with emailed wellbeing resources. Participants were emailed an on-line survey asking questions about value and novelty of the sessions, and work satisfaction and stress, as well as open comments. A request for an additional interview to explore responses in more depth was included. Fifty interns attended at least one of the sessions and 35 participated in the survey, six to an additional interview. Survey and interview data showed that the majority of interns perceived the sessions as valuable, relevant and useful and felt that ongoing sessions would benefit junior medical officers (JMOs) in future years. Feedback highlighted the importance of providing future sessions in-person, incorporating an interactive approach and emphasized that work site factors and medical culture play a large causative role in their stress. We conclude that wellbeing sessions are acceptable and useful to interns and should be incorporated into hospital teaching curricula, and evaluated. However these programs are unlikely to change the high stress experienced unless external and systemic stressors are addressed by all stakeholders. This article is protected by copyright.

2016-01-01

A long-distance training course was implemented to the academic program which teaches ethics to future doctors. Its main objective was to develop students' individual patient care skills to carry out an analysis on ethically problematic situations. Such procedures may seem paradoxical in a training course which aims to develop one's sensitivity to others; it does however help to accommodate the geographical constraints linked to students accessing their practical training (in a country's different hospitals or abroad) and provides students with a introductory course on e-learning organised by their university's learning centre. Said course provided a rigorous structure in view of preparing for this procedure, alternating meetings with work hours via a digital platform: precise and measurable objectives, scripted sequences, clear guidelines, diverse activities. Organising work around 4 progress reports provided students with some reassurance but also a degree of autonomy, reflecting what they will be able to offer their future patients. All interactions suggested by the teacher were successfully carried out via the platform (individually on one hand, in the context of a forum on the other hand) but also using collective supervision for certain students. The advantages of such a procedure have been highlighted by evaluating students' levels of satisfaction (via an online questionnaire), but also levels of personal involvement in their work. One dimension in particular deserves further attention: the place occupied by writing in the study of ethics, as well as patient care in general.

A patient and public involvement (PPI) toolkit for meaningful and flexible involvement in clinical trials - a work in progress.

Funders of research are increasingly requiring researchers to involve patients and the public in their research. Patient and public involvement (PPI) in research can potentially help researchers make sure that the design of their research is relevant, that it is participant friendly and ethically sound. Using and sharing PPI resources can benefit those involved in undertaking PPI, but existing PPI resources are not used consistently and this can lead to duplication of effort. This paper describes how we are developing a toolkit to support clinical trials teams in a clinical trials unit. The toolkit will provide a key 'off the shelf' resource to support trial teams with limited resources, in undertaking PPI. Key activities in further developing and maintaining the toolkit are to: ● listen to the views and experience of both research teams and patient and public contributors who use the tools; ● modify the tools based on our experience of using them; ● identify the need for future tools; ● update the toolkit based on any newly identified resources that come to light; ● raise awareness of the toolkit and ● work in collaboration with others to either develop or test out PPI resources in order to reduce duplication of work in PPI. Background Patient and public involvement (PPI) in research is increasingly a funder requirement due to the potential benefits in the design of relevant, participant friendly, ethically sound research. The use and sharing of resources can benefit PPI, but available resources are not consistently used leading to duplication of effort. This paper describes a developing toolkit to support clinical trials teams to undertake effective and meaningful PPI. Methods The first phase in developing the toolkit was to describe which PPI activities should be considered in the pathway of a clinical trial and at what stage these activities should take place. This pathway was informed through review of the type and timing of PPI activities within trials coordinated by the Clinical Trials Research Centre and previously described areas of potential PPI impact in trials. In the second phase, key websites around PPI and identification of resources opportunistically, e.g. in conversation with other trialists or social media, were used to identify resources. Tools were developed where gaps existed. Results A flowchart was developed describing PPI activities that should be considered in the clinical trial pathway and the point at which these activities should happen. Three toolkit domains were identified: planning PPI; supporting PPI; recording and evaluating PPI. Four main activities and corresponding tools were identified under the planning for PPI: developing a plan; identifying patient and public contributors; allocating appropriate costs; and managing expectations. In supporting PPI, tools were developed to review participant information sheets. These tools, which require a summary of potential trial participant characteristics and circumstances help to clarify requirements and expectations of PPI review. For recording and evaluating PPI, the planned PPI interventions should be monitored in terms of impact, and a tool to monitor public contributor experience is in development. Conclusions This toolkit provides a developing 'off the shelf' resource to support trial teams with limited resources in undertaking PPI. Key activities in further developing and maintaining the toolkit are to: listen to the views and experience of both research teams and public contributors using the tools, to identify the need for future tools, to modify tools based on experience of their use; to update the toolkit based on any newly identified resources that come to light; to raise awareness of the toolkit and to work in collaboration with others to both develop and test out PPI resources in order to reduce duplication of work in PPI.

1999-06-01

New class of automobiles has structural skins that are quite different from their current designs. Particularly, new families of composite skins are developed with new injection molding processes. These skins while support the concept of lighter vehicles of the future, are also susceptible to damage upon impact. It is important that their design should be based on a better understanding on the type of impact loads and the resulting strains and damage. It is possible that these skins can be integrally designed with active materials to counter damages. This paper presents a preliminary analysis of a new class of automotive skins, using piezoceramic as a smart material. The main objective is to consider the complex system with, the skin to be modeled as a layered plate structure involving a lightweight material with foam and active materials imbedded on them. To begin with a cantilever beam structure is subjected to a load through piezoceramic and the resulting strain at the active material site is predicted accounting for the material properties, piezoceramic thickness, adhesive thickness including the effect of adhesives. A finite element analysis is carried out to compare experimental work. Further work in this direction would provide an analytical tool that will provide the basis for algorithms to predict and counter impacts on the future class of automobiles.

There is mounting evidence that sleep is important for learning, memory and the underlying neural plasticity. This article aims to review published studies that evaluate the association between sleep, its distinct stages and memory systems in healthy children and adolescents. Furthermore it intends to suggest directions for future research. A computerised search of the literature for relevant articles published between 1966 and March 2008 was performed using the keywords "sleep", "memory", "learn", "child", "adolescents", "adolescence" and "teenager". Fifteen studies met the inclusion criteria. Published studies focused on the impact of sleep on working memory and memory consolidation. In summary, most studies support the hypothesis that sleep facilitates working memory as well as memory consolidation in children and adolescents. There is evidence that performance in abstract and complex tasks involving higher brain functions declines more strongly after sleep deprivation than the performance in simple memory tasks. Future studies are needed to better understand the impact of a variety of variables potentially modulating the interplay between sleep and memory, such as developmental stage, socioeconomic burden, circadian factors, or the level of post-learning sensory and motor activity (interference). This line of research can provide valuable input relevant to teaching, learning and public health policy. Copyright 2009 Elsevier Ltd. All rights reserved.

Children's Gender Identity in Lesbian and Heterosexual Two-Parent Families.

Bos, Henny; Sandfort, Theo G M

2010-01-01

This study compared gender identity, anticipated future heterosexual romantic involvement, and psychosocial adjustment of children in lesbian and heterosexual families; it was furthermore assessed whether associations between these aspects differed between family types. Data were obtained in the Netherlands from children in 63 lesbian families and 68 heterosexual families. All children were between 8 and 12 years old. Children in lesbian families felt less parental pressure to conform to gender stereotypes, were less likely to experience their own gender as superior and were more likely to be uncertain about future heterosexual romantic involvement. No differences were found on psychosocial adjustment. Gender typicality, gender contentedness and anticipated future heterosexual romantic involvement were significant predictors of psychosocial adjustment in both family types.

Thermodynamic data are essential for understanding and evaluating geochemical processes, as by speciation-solubility calculations, reaction -path modeling, or reactive transport simulation. These data are required to evaluate both equilibrium states and the kinetic approach to such states (via the affinity term in rate laws). The development of thermodynamic databases for these purposes has a long history in geochemistry (e.g., Garrels and Christ, 1965; Helgeson et al., 1969; Helgeson et al., 1978, Johnson et al., 1992; Robie and Hemingway, 1995), paralleled by related and applicable work in the larger scientific community (e.g., Wagman et al., 1982, 1989; Cox et al., 1989;more » Barin and Platzki, 1995; Binneweis and Milke, 1999). The Yucca Mountain Project developed two qualified thermodynamic databases for to model geochemical processes, including ones involving repository components such as spent fuel. The first of the two (BSC, 2007a) was for systems containing dilute aqueous solutions only, the other (BSC, 2007b) for systems involving concentrated aqueous solutions and incorporating a model for such based on Pitzer’s (1991) equations . A 25°C-only database with similarities to the latter was also developed for WIPP (cf. Xiong, 2005). The YMP dilute systems database is widely used in the geochemistry community for a variety of applications involving rock/water interactions. The purpose of the present task is to improve these databases for work on the Used Fuel Disposition Project and maintain some semblance of order that will support qualification in support of the development of future underground high level nuclear waste disposal.« less

Emotion-focused family therapy is a transdiagnostic approach that affords parents and caregivers a significant role in their loved one's recovery from an eating disorder. A 2-day intervention was developed on the basis of emotion-focused family therapy principles and delivered to 33 parents of adolescent and adult children. Data were collected pre- and post-intervention. Through education and skills practice, parents were taught strategies with respect to meal support and symptom interruption as well as emotion coaching. Parents were also supported to identify and work through their own emotional blocks that could interfere with their supportive efforts. Analyses revealed a significant increase in parental self-efficacy, a positive shift in parents' attitudes regarding their role as emotion coach and a reduction in the fears associated with their involvement in treatment, including a decrease in self-blame. Overall, this broad-based, low-cost intervention shows promise, and future research is warranted. Copyright © 2014 John Wiley & Sons, Ltd. A low-cost, intensive emotion-focused family therapy intervention shows promise for parents of individuals with an eating disorder, regardless of their loved one's age, symptom profile or involvement in treatment. Working with parents' emotions and emotional reactions to their child's struggles has the potential to improve supportive efforts. An emotion-focused family therapy intervention for parents yields high satisfaction rates, improves parental self-efficacy and reduces fears regarding their involvement, including self-blame.

There are well-established training programmes available to support health and human services professionals working with people vulnerable to suicide. However, little is known about involving people with lived experience in the delivery of suicide prevention training with communities with increased rates of suicide. The aim of this paper was to report on a formative dialogical evaluation that explored the views of health and human services workers with regard to a suicide prevention training programme in regional (including rural and remote areas) South Australia which included meaningful involvement of a person with lived experience in the development and delivery of the training. In 2015, eight suicide prevention training workshops were conducted with health and human services workers. All 248 participants lived and worked in South Australian regional communities. We interviewed a subsample of 24 participants across eight sites. A thematic analysis of the interviews identified five themes: Coproduction is key, It is okay to ask the question, Caring for my community, I can make a difference and Learning for future training. The overall meta-theme was "Involvement of a person with lived experience in suicide prevention training supports regional communities to look out for people at risk of suicide." This paper highlights the need for suicide prevention training and other workforce development programmes to include lived experience participation as a core component in development and delivery. © 2018 John Wiley & Sons Ltd.

Participation of South African youth in the design and development of AIDS photocomics. 1997-98.

PubMed

Toroyan, Tamitza; Reddy, Priscilla S

In response to an increasing incidence in HIV prevalence among South Africa's youth, a group of interdisciplinary professionals have developed a series of photocomics to address issues around HIV/AIDS communication and sexually transmitted diseases. This article examines the theory behind the use of photocomics in health, and the way the stories work to influence behavior. Results from evaluation of the comics support their use as tools with which to increase information and knowledge while role modeling desirable behavior. Lastly, the article describes the participatory process by which youth were involved in the process of developing and producing the comics. This method of developing culturally relevant and appealing health media is recommended for use in future health promotion strategies that seek to transcend a narrower approach of provision of health information and work to address the social factors that influence youth's decision making.

Employers and workers need concrete guidance to plan and implement changes in the ergonomics of computer workstations. The Näppärä method is a screening tool for identifying problems requiring further assessment and corrective actions. The aim of this study was to assess the work of occupational safety and health (OSH) government inspectors who used Näppärä as part of their OSH enforcement inspections (430 assessments) related to computer work. The modifications in workstation ergonomics involved mainly adjustments to the screen, mouse, keyboard, forearm supports, and chair. One output of the assessment is an index indicating the percentage of compliance items. This method can be considered as exposure assessment and ergonomics intervention used as a benchmark for the level of ergonomics. Future research can examine whether the effectiveness of participatory ergonomics interventions should be investigated with Näppärä.

NASA's Exploration Systems Mission Directorate (ESMD) is implementing a management approach for modeling and simulation (M&S) that will provide decision-makers information on the model s fidelity, credibility, and quality. The Integrated Modeling & Simulation Verification, Validation and Accreditation (IM&S W&A) process will allow the decision-maker to understand the risks involved in using a model s results for mission-critical decisions. The W&A Technical Working Group (W&A TWG) has been identified to communicate this process throughout the agency. As the W&A experts, the W&A NVG will be the central resource for support of W&A policy, procedures, training and templates for documentation. This presentation will discuss the W&A Technical Working Group s outreach approach aimed at educating M&S program managers, developers, users and proponents on the W&A process, beginning at MSFC with the CLV program.

Study of Acoustic Emissions from Composites

Walker, James L.; Workman, Gary L.

1997-01-01

The nondestructive evaluation (NDE) of future propulsion systems utilizing advanced composite structures for the storage of cryogenic fuels, such as liquid hydrogen or oxygen, presents many challenges. Economic justification for these structures requires light weight, reusable components with an infrastructure allowing periodic evaluation of structural integrity after enduring demanding stresses during operation. A major focus has been placed on the use of acoustic emission NDE to detect propagating defects, in service, necessitating an extensive study into characterizing the nature of acoustic signal propagation at very low temperatures and developing the methodology of applying AE sensors to monitor cryogenic components. This work addresses the question of sensor performance in the cryogenic environment. Problems involving sensor mounting, spectral response and durability are addressed. The results of this work provides a common point of measure from which sensor selection can be made when testing composite components at cryogenic temperatures.

The Value of Animations in Biology Teaching: A Study of Long-Term Memory Retention

PubMed Central

2007-01-01

Previous work has established that a narrated animation is more effective at communicating a complex biological process (signal transduction) than the equivalent graphic with figure legend. To my knowledge, no study has been done in any subject area on the effectiveness of animations versus graphics in the long-term retention of information, a primary and critical issue in studies of teaching and learning. In this study, involving 393 student responses, three different animations and two graphics—one with and one lacking a legend—were used to determine the long-term retention of information. The results show that students retain more information 21 d after viewing an animation without narration compared with an equivalent graphic whether or not that graphic had a legend. Students' comments provide additional insight into the value of animations in the pedagogical process, and suggestions for future work are proposed. PMID:17785404

2003-03-01

In an effort to stimulate and guide empirical work within a functional framework, this paper provides a conceptual model of the social functions of autobiographical memory (AM) across the lifespan. The model delineates the processes and variables involved when AMs are shared to serve social functions. Components of the model include: lifespan contextual influences, the qualitative characteristics of memory (emotionality and level of detail recalled), the speaker's characteristics (age, gender, and personality), the familiarity and similarity of the listener to the speaker, the level of responsiveness during the memory-sharing process, and the nature of the social relationship in which the memory sharing occurs (valence and length of the relationship). These components are shown to influence the type of social function served and/or, the extent to which social functions are served. Directions for future empirical work to substantiate the model and hypotheses derived from the model are provided.

Dissemination and implementation science addresses the application of research findings in varied health care settings. Despite the potential benefit of dissemination and implementation work to primary care, ideal laboratories for this science have been elusive. Practice-based research networks (PBRNs) have a long history of conducting research in community clinical settings, demonstrating an approach that could be used to execute multiple research projects over time in broad and varied settings. PBRNs also are uniquely structured and increasingly involved in pragmatic trials, a research design central to dissemination and implementation science. We argue that PBRNs and dissemination and implementation scientists are ideally suited to work together and that the collaboration of these 2 groups will yield great value for the future of primary care and the delivery of evidence-based health care. © Copyright 2014 by the American Board of Family Medicine.

As a part of larger effort to enhance the research activity at SC State and involve more undergraduates in research activities, we present our efforts to develop an introductory research experience where the goal is a balance of astrophysical understanding, general research skills, and programming skills which the students can carry into a wide variety of future research activities. We have found that variable stars are a very good topic for this sort of introductory experience due to a combination of factors including: accessibility of data, easily understandable physical processes, and a relatively straight forward data analysis process. We will present an outline of our research experiences to guide a student from the very initial stages of learning to final presentation of the student's work.“This work was supported in part by NSF PAARE award AST-1358913 and NSF HBCU-UP award HRD-1332449 to SCSU.”

Investigation of Integrated Vehicle Health Management Approaches

2005-01-01

This report is to present the work that was performed during the summer in the Advance Computing Application office. The NFFP (NASA Faculty Fellow Program) had ten summer faculty members working on IVHM (Integrated Vehicle Health Management) technologies. The objective of this project was two-fold: 1) to become familiar with IVHM concepts and key demonstrated IVHM technologies; and 2) to integrate the research that has been performed by IVHM faculty members into the MASTLAB (Marshall Avionic Software Test Lab). IVHM is a NASA-wide effort to coordinate, integrate and apply advanced software, sensors and design technologies to increase the level of intelligence, autonomy, and health state of future vehicles. IVHM is an important concept because it is consistent with the current plan for NASA to go to the moon, mars, and beyond. In order for NASA to become more involved in deep exploration, avionic systems will need to be highly adaptable and autonomous.

A trial of an alternative to the traditional 4-on/8-off watchkeeping system was made on a container ship during a round trip from Europe to the Far East. The three navigating officers on the ship operated the new system, which involved "compressed" working hours with a long unbroken period of rest, during two sections of the voyage, one of which included six stops at ports. Despite unforeseen problems arising mainly from these stops, questionnaire responses concerning the new system were not altogether unfavourable to it, and daily records kept by the officers gave some support to the hypothesis that sleep would be better than under the traditional system. However, a number of difficulties were encountered; these are discussed in relation to the design of future studies of alternative watchkeeping systems.

The chronology covers 30 years of cooperation between the U.S. and the Soviet Union (and its successor, the Commonwealth of Independent States, of which the Russian Federation is the leading space power). It tracks successful cooperative projects and failed attempts at space cooperation. Included are the Dryden-Blagonravov talks; the UN Space Treaties; the Apollo Soyuz Test Project; COSPAS-SARSAT; the abortive Shuttle-Salyut discussions; widespread calls for joint manned and unmanned exploration of Mars; conjectural plans to use Energia and other Russian space hardware in ambitious future joint missions; and contemporary plans involving the U.S. Shuttle, Russian Mir, and Soyuz-TM. The chronology also includes events not directly related to space cooperation to provide context. A bibliography lists works and individuals consulted in compiling the chronology, plus works not used but relevant to the topic of space cooperation.

Improved Subcell Model for the Prediction of Braided Composite Response

Cater, Christopher R.; Xinran, Xiao; Goldberg, Robert K.; Kohlman, Lee W.

2013-01-01

In this work, the modeling of triaxially braided composites was explored through a semi-analytical discretization. Four unique subcells, each approximated by a "mosaic" stacking of unidirectional composite plies, were modeled through the use of layered-shell elements within the explicit finite element code LS-DYNA. Two subcell discretizations were investigated: a model explicitly capturing pure matrix regions, and a novel model which absorbed pure matrix pockets into neighboring tow plies. The in-plane stiffness properties of both models, computed using bottom-up micromechanics, correlated well to experimental data. The absorbed matrix model, however, was found to best capture out-of- plane flexural properties by comparing numerical simulations of the out-of-plane displacements from single-ply tension tests to experimental full field data. This strong correlation of out-of-plane characteristics supports the current modeling approach as a viable candidate for future work involving impact simulations.

The International Dermatology Outcome Measures (IDEOM) psoriasis working group was established to develop core domains and measurements sets for psoriasis clinical trials and ultimately clinical practice. At the 2016 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis, the IDEOM psoriasis group presented an overview of its progress toward developing this psoriasis core domain set. First, it summarized the February 2016 meeting of all involved with the IDEOM, highlighting patient and payer perspectives on outcome measures. Second, the group presented an overview of the consensus process for developing the core domain set for psoriasis, including previous literature reviews, nominal group exercises, and meeting discussions. Future plans include the development of working groups to review candidate measures for at least 2 of the domains, including primary pathophysiologic manifestations and patient-reported outcomes, and Delphi surveys to gain consensus on the final psoriasis core domain set.

Stressors of Korean Disaster Relief Team Members during the Nepal Earthquake Dispatch: a Consensual Qualitative Research Analysis.

2017-03-01

We conducted in-depth interviews with 11 Korean Disaster Relief Team (KDRT) members about stress related to disaster relief work and analyzed the interview data using the Consensual Qualitative Research (CQR) method in order to evaluate difficulties in disaster relief work and to develop solutions to these problems in cooperation with related organizations. Results showed that members typically experienced stress related to untrained team members, ineffective cooperation, and the shock and aftermath of aftershock experiences. Stress tended to stem from several factors: difficulties related to cooperation with new team members, the frightening disaster experience, and the aftermath of the disaster. Other stressors included conflict with the control tower, diverse problems at the disaster relief work site, and environmental factors. The most common reason that members participated in KDRT work despite all the stressors and difficulties was pride about the kind of work it involved. Many subjects in this study suffered from various stresses after the relief work, but they had no other choice than to attempt to forget about their experiences over time. It is recommended that the mental health of disaster relief workers will improve through the further development of effective treatment and surveillance programs in the future.

The benefits of a fast reactor closed fuel cycle in the UK

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

Gregg, R.; Hesketh, K.

2013-07-01

The work has shown that starting a fast reactor closed fuel cycle in the UK, requires virtually all of Britain's existing and future PWR spent fuel to be reprocessed, in order to obtain the plutonium needed. The existing UK Pu stockpile is sufficient to initially support only a modest SFR 'closed' fleet assuming spent fuel can be reprocessed shortly after discharge (i.e. after two years cooling). For a substantial fast reactor fleet, most Pu will have to originate from reprocessing future spent PWR fuel. Therefore, the maximum fast reactor fleet size will be limited by the preceding PWR fleet size,more » so scenarios involving fast reactors still require significant quantities of uranium ore indirectly. However, once a fast reactor fuel cycle has been established, the very substantial quantities of uranium tails in the UK would ensure there is sufficient material for several centuries. Both the short and long term impacts on a repository have been considered in this work. Over the short term, the decay heat emanating from the HLW and spent fuel will limit the density of waste within a repository. For scenarios involving fast reactors, the only significant heat bearing actinide content will be present in the final cores, resulting in a 50% overall reduction in decay energy deposited within the repository when compared with an equivalent open fuel cycle. Over the longer term, radiological dose becomes more important. Total radiotoxicity (normalised by electricity generated) is lower for scenarios with Pu recycle after 2000 years. Scenarios involving fast reactors have the lowest radiotoxicity since the quantities of certain actinides (Np, Pu and Am) eventually stabilise. However, total radiotoxicity as a measure of radiological risk does not account for differences in radionuclide mobility once in repository. Radiological dose is dominated by a small number of fission products so is therefore not affected significantly by reactor type or recycling strategy (since the fission product will primarily be a function of nuclear energy generated). However, by reprocessing spent fuel, it is possible to immobilise the fission product in a more suitable waste form that has far more superior in-repository performance. (authors)« less

Encouraging and Attracting Underrepresented Racial Minorities to the Field of Geosciences-A Latin American Graduate Student Perspective

NASA Astrophysics Data System (ADS)

Caballero Gill, R. P.; Herbert, T.

2010-12-01

Recent studies have shown that interactions between same-race and same-gender faculty and graduate students are reported to have a greater impact on the future success of those students. In the same manner, I believe graduate students can play a pivotal role in training and attracting underrepresented racial minorities (URMs) at the high school and undergraduate level to pursue a career in geosciences. Working at Brown University for the last couple of years, I have been involved in a number of initiatives aimed at solidifying ties with the community. Most of my social work has revolved around mentoring underrepresented local minorities, as I feel that this area is where I can contribute the most. This year I began participating in the NSF funded Brown GK-12: "Physical Processes in the Environment" program. As a Latin American female graduate student in the geological sciences, I hope to teach the students-by example-that being a minority is not necessarily an obstacle, but rather an advantage that can offer a different, valuable point of view when pursuing their professional goals. I think that sharing part of my experiences and knowledge as a researcher with young minds contributes to the way they imagine themselves in the future, allowing them to believe that a career in science is within their reach and that higher education is a realistic option worth pursuing if they have the interest in doing so. From my short time as a graduate student, to have a greater impact in attracting URMs, it is critical to have the support of advisors and committee members. One must keep in mind that a graduate career is a time consuming commitment; therefore, it is necessary to undertake activities that will have the most impact on minority students in the short time available. The experience becomes even more effective if advisors are actively involved, particularly financially. Faculty advisors who can allocate funds to, for example support summer activities designed to involve URMs, are essentially leveraging funds because the overall return will be much greater than the initial investment.

Universal Skills and Competencies for Geoscientists

NASA Astrophysics Data System (ADS)

Mosher, S.

2015-12-01

Geoscience students worldwide face a changing future workforce, but all geoscience work has universal cross-cutting skills and competencies that are critical for success. A recent Geoscience Employers Workshop, and employers' input on the "Future of Undergraduate Geoscience Education" survey, identified three major areas. Geoscience work requires spatial and temporal (3D & 4D) thinking, understanding that the Earth is a system of interacting parts and processes, and geoscience reasoning and synthesis. Thus, students need to be able to solve problems in the context of an open and dynamic system, recognizing that most geoscience problems have no clear, unambiguous answers. Students must learn to manage uncertainty, work by analogy and inference, and make predations with limited data. Being able to visualize and solve problems in 3D, incorporate the element of time, and understand scale is critical. Additionally students must learn how to tackle problems using real data, including understand the problems' context, identify appropriate questions to ask, and determine how to proceed. Geoscience work requires integration of quantitative, technical, and computational skills and the ability to be intellectually flexible in applying skills to new situations. Students need experience using high-level math and computational methods to solve geoscience problems, including probability and statistics to understand risk. Increasingly important is the ability to use "Big Data", GIS, visualization and modeling tools. Employers also agree a strong field component in geoscience education is important. Success as a geoscientist also requires non-technical skills. Because most work environments involve working on projects with a diverse team, students need experience with project management in team settings, including goal setting, conflict resolution, time management and being both leader and follower. Written and verbal scientific communication, as well as public speaking and listening skills, are important. Success also depends on interpersonal skills and professionalism, including business acumen, risk management, ethical conduct, and leadership. A global perspective is increasingly important, including cultural literacy and understanding societal relevance.

Involving patients in health technology funding decisions: stakeholder perspectives on processes used in Australia.

PubMed

Lopes, Edilene; Street, Jackie; Carter, Drew; Merlin, Tracy

2016-04-01

Governments use a variety of processes to incorporate public perspectives into policymaking, but few studies have evaluated these processes from participants' point of view. The objective of this study was twofold: to understand the perspectives of selected stakeholders with regard to involvement processes used by Australian Advisory Committees to engage the public and patients; and to identify barriers and facilitators to participation. Twelve semi-structured interviews were conducted with representatives of different stakeholder groups involved in health technology funding decisions in Australia. Data were collected and analysed using a theoretical framework created by Rowe and Frewer, but adapted to more fully acknowledge issues of power and influence. Stakeholder groups disagreed as to what constitutes effective and inclusive patient involvement. Barriers reported by interviewees included poor communication, a lack of transparency, unworkable deadlines, and inadequate representativeness. Also described were problems associated with defining the task for patients and their advocates and with the timing of patient input in the decision-making process. Interviewees suggested that patient participation could be improved by increasing the number of patient organizations engaged in processes and including those organizations at different stages of decision making, especially earlier. The different evaluations made by stakeholder groups appear to be underpinned by contrasting conceptions of public involvement and its value, in line with Graham Martin's work which distinguishes between 'technocratic' and 'democratic' public involvement. Understanding stakeholders' perspectives and the contrasting conceptions of public involvement could foster future agreement on which processes should be used to involve the public in decision making. © 2015 John Wiley & Sons Ltd.

In the near future, workforces will increasingly consist of older workers. At the same time, research has demonstrated that work-related growth motives decrease with age. Although this finding is consistent with life span theories, such as the selection optimization and compensation (SOC) model, we know relatively little about the process variables that bring about this change in work motivation. Therefore, we use a 4-wave study design to examine the mediating role of future time perspective and promotion focus in the negative association between age and work-related growth motives. Consistent with the SOC model, we found that future time perspective was negatively associated with age, which, in turn, was associated with lower promotion focus, lower work-related growth motive strength, and lower motivation to continue working. These findings have important theoretical implications for the literature on aging and work motivation, and practical implications for how to motivate older workers.

Dependence of future mortality changes on global CO2 concentrations: A review.

PubMed

Lee, Jae Young; Choi, Hayoung; Kim, Ho

The heterogeneity among previous studies of future mortality projections due to climate change has often hindered comparisons and syntheses of resulting impacts. To address this challenge, the present study introduced a novel method to normalize the results from projection studies according to different baseline and projection periods and climate scenarios, thereby facilitating comparison and synthesis. This study reviewed the 15 previous studies involving projected climate change-related mortality under Representative Concentration Pathways. To synthesize their results, we first reviewed the important study design elements that affected the reported results in previous studies. Then, we normalized the reported results by CO 2 concentration in order to eliminate the effects of the baseline period, projection period, and climate scenario choices. For twenty-five locations worldwide, the normalized percentage changes in temperature-attributable mortality per 100 ppm increase in global CO 2 concentrations ranged between 41.9% and 330%, whereas those of total mortality ranged between 0.3% and 4.8%. The normalization methods presented in this work will guide future studies to provide their results in a normalized format and facilitate research synthesis to reinforce our understanding on the risk of climate change.

Italy is a country at risk of impending earthquake in the near future. Very probably, as it has already happened in the 13 years between the last two important seismic events (Colfiorito 1997- L'Aquila 2009), there won't be enough time to solve all the problems connected to seismic risk: first of all the corruption related to politics concerning buildings; the lack of the money necessary to strengthen the already existing ones, historical centres, monuments and the masterpieces of Art; the difficult relations of the Institutions with the traditional media (newspapers, radio and TV) and, at the same time, the new media (web); the difficulties for scientists to reach important results in the immediate future due to the lack of funding and, last but not least, to the conflicting relationships inside the scientific community itself. In this scenario, communication and education play a crucial role in minimizing the risk of the population. In the present work we reconsider the past with the intent of starting to trace a path for a future strategy of risk communication where everybody involved, included the population, should do his best in order to face the next emergency.

A toolkit for incorporating genetics into mainstream medical services: Learning from service development pilots in England

PubMed Central

2010-01-01

Background As advances in genetics are becoming increasingly relevant to mainstream healthcare, a major challenge is to ensure that these are integrated appropriately into mainstream medical services. In 2003, the Department of Health for England announced the availability of start-up funding for ten 'Mainstreaming Genetics' pilot services to develop models to achieve this. Methods Multiple methods were used to explore the pilots' experiences of incorporating genetics which might inform the development of new services in the future. A workshop with project staff, an email questionnaire, interviews and a thematic analysis of pilot final reports were carried out. Results Seven themes relating to the integration of genetics into mainstream medical services were identified: planning services to incorporate genetics; the involvement of genetics departments; the establishment of roles incorporating genetic activities; identifying and involving stakeholders; the challenges of working across specialty boundaries; working with multiple healthcare organisations; and the importance of cultural awareness of genetic conditions. Pilots found that the planning phase often included the need to raise awareness of genetic conditions and services and that early consideration of organisational issues such as clinic location was essential. The formal involvement of genetics departments was crucial to success; benefits included provision of clinical and educational support for staff in new roles. Recruitment and retention for new roles outside usual career pathways sometimes proved difficult. Differences in specialties' working practices and working with multiple healthcare organisations also brought challenges such as the 'genetic approach' of working with families, incompatible record systems and different approaches to health professionals' autonomous practice. 'Practice points' have been collated into a Toolkit which includes resources from the pilots, including job descriptions and clinical tools. These can be customised for reuse by other services. Conclusions Healthcare services need to translate advances in genetics into benefits for patients. Consideration of the issues presented here when incorporating genetics into mainstream medical services will help ensure that new service developments build on the body of experience gained by the pilots, to provide high quality services for patients with or at risk of genetic conditions.

Diagnostics of Carbon Nanotube Formation in a Laser Produced Plume: An Investigation of the Metal Catalyst by Laser Ablation Atomic Fluorescence Spectroscopy

NASA Technical Reports Server (NTRS)

deBoer, Gary; Scott, Carl

2003-01-01

Carbon nanotubes, elongated molecular tubes with diameters of nanometers and lengths in microns, hold great promise for material science. Hopes for super strong light-weight material to be used in spacecraft design is the driving force behind nanotube work at JSC. The molecular nature of these materials requires the appropriate tools for investigation of their structure, properties, and formation. The mechanism of nanotube formation is of particular interest because it may hold keys to controlling the formation of different types of nanotubes and allow them to be produced in much greater quantities at less cost than is currently available. This summer's work involved the interpretation of data taken last summer and analyzed over the academic year. The work involved diagnostic studies of carbon nanotube formation processes occurring in a laser-produced plume. Laser ablation of metal doped graphite to produce a plasma plume in which carbon nanotubes self assemble is one method of making carbon nanotube. The laser ablation method is amenable to applying the techniques of laser spectroscopy, a powerful tool for probing the energies and dynamics of atomic and molecular species. The experimental work performed last summer involved probing one of the metal catalysts, nickel, by laser induced fluorescence. The nickel atom was studied as a function of oven temperature, probe laser wavelength, time after ablation, and position in the laser produced plume. This data along with previously obtained data on carbon was analyzed over the academic year. Interpretations of the data were developed this summer along with discussions of future work. The temperature of the oven in which the target is ablated greatly influences the amount of material ablated and the propagation of the plume. The ablation conditions and the time scale of atomic and molecular lifetimes suggest that initial ablation of the metal doped carbon target results in atomic and small molecular species. The metal atoms survive for several milliseconds while the gaseous carbon atoms and small molecules nucleate more rapidly. Additional experiments and the development of in situ methods for carbon nanotube detection would allow these results to be interpreted from the perspective of carbon nanotube formation.

Like most industrialised countries, Switzerland has introduced legislation to protect the health of pregnant workers and their unborn children from workplace exposure. This legislation provides for a risk assessment, adaptations to workplaces and, if the danger is not eliminated, preventive leave (prescribed by a gynaecologist). This study's first objective is to analyse the degree to which companies, gynaecologists and midwives implement the law. Its second objective is to understand the obstacles and resources of this implementation, with a focus on how relevant stakeholders perceive protective measures and their involvement with them. Data will be collected using mixed methods: (1) online questionnaires for gynaecologists and midwives; telephone questionnaires with company human resources (HR) managers in the healthcare and food production sectors; (2a) case studies of 6-8 companies in each sector, including interviews with stakeholders such as women workers, HR managers and occupational health physicians; (2b) two focus groups, one involving occupational physicians and hygienists, one involving labour inspectors.Quantitative data will be analysed statistically using STATA software V.15. Qualitative data will be transcribed and thematically analysed using MaxQDA software. The Human Research Ethics Committee of the Canton Vaud (CER-VD) has certified that this research study protocol falls outside of the field of application of the Swiss Federal Act on Research Involving Humans.The publications and recommendations resulting from this study will form the starting point for future improvements to the protection of pregnant women at work and their unborn children.This study started in February 2017 and will continue until January 2020. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Medical education, based on the principles of social medicine, has the ability to contribute to reducing health disparities through the "creation" of doctors who are more involved in community programs. To compare the social and community orientation of graduates from the various medical schools. An online cross-sectional survey among 12,000 physicians who are graduates of Israeli medical schools was conducted in May 2011. The study encompassed 1,050 physicians, Israeli medical school graduates living in Israel and practicing medicine: 36% were Hebrew University graduates, 26% were Tel Aviv University graduates, 22% were Technion graduates and 16% were Ben-Gurion University (BGU) graduates. Higher rates of physicians who studied at the Technion and BGU are working or have worked in the periphery (approximately 50% vs. approximately 30% average of Hebrew and Tel-Aviv University schools). Among BGU graduates, 47% are active in community programs vs. 34-38% in other schools. Among physicians active in community programs, 32% of BGU alumni estimated that their medical education greatly influenced their community involvement vs. 8-15% in other schools. Hebrew University alumni graded their studies as having a higher research orientation. In contrast, BGU graduates graded their studies as having a higher social orientation, and had more positive attitudes on the role of the physician in reducing health disparities. Medical education with a social orientation will induce a socialization process that reinforces human values regarding the doctor-patient relationship and produce positive attitudes among future doctors regarding their social involvement. The findings emphasize the need to develop educational programs with a social orientation and to strengthen medical schools in the periphery.

Why social attachment and oxytocin protect against addiction and stress: Insights from the dynamics between ventral and dorsal corticostriatal systems.

PubMed

Tops, Mattie; Koole, Sander L; IJzerman, Hans; Buisman-Pijlman, Femke T A

2014-04-01

The present article advances a neurobiological model of the reciprocal associations between social attachment and drug abuse, and social attachment and chronic stress, as overlapping systems are involved in stress coping and social attachment. In terms of coping, responding to a novel stressor or challenge involves initial novelty processing and activation of learning mechanisms that allow habituation to the stressor through familiarization. Similarly, social attachments are initially formed by being attracted by rewarding properties of an as-yet novel individual, and subsequently developing feelings of attachment towards the familiarized individual. Attachment and familiarization increase the availability of "internal working models" for the control of behavior and emotion, which may explain why secure attachments are associated with increased resilience in the face of stress, accompanied by less reactive reward responding (i.e., increased resilience against drug addiction). The present article seeks to illuminate the role of the neuropeptide oxytocin, which may be involved in the overlapping mechanisms of stable attachment formation and stress coping by shifting processing from novelty and reward seeking to appreciation of familiarity. Oxytocin may accomplish this by facilitating a ventral-to-dorsal shift in activation in corticostriatal loops, which produces a shift from a reactive reward drive (wanting) to stable appreciation of familiar social aspects ("liking" or "loving"). The authors suggest that through dopaminergic, serotonergic and endogenous opioid mechanisms, oxytocin is involved in shifting the balance between wanting and liking in corticostriatal loops by facilitating consolidation of social information from ventral reactive reward systems to dorsal internal working models that aid in prospectively selecting optimal actions in the future, increasing resilience in the face of stress and addiction. © 2013.

Do TRPC channels support working memory? Comparing modulations of TRPC channels and working memory through G-protein coupled receptors and neuromodulators.

Working memory is a crucial ability we use in daily life. However, the cellular mechanisms supporting working memory still remain largely unclear. A key component of working memory is persistent neural firing which is believed to serve short-term (hundreds of milliseconds up to tens of seconds) maintenance of necessary information. In this review, we will focus on the role of transient receptor potential canonical (TRPC) channels as a mechanism underlying persistent firing. Many years of in vitro work have been suggesting a crucial role of TRPC channels in working memory and temporal association tasks. If TRPC channels are indeed a central mechanism for working memory, manipulations which impair or facilitate working memory should have a similar effect on TRPC channel modulation. However, modulations of working memory and TRPC channels were never systematically compared, and it remains unanswered whether TRPC channels indeed contribute to working memory in vivo or not. In this article, we review the effects of G-protein coupled receptors (GPCR) and neuromodulators, including acetylcholine, noradrenalin, serotonin and dopamine, on working memory and TRPC channels. Based on comparisons, we argue that GPCR and downstream signaling pathways that activate TRPC, generally support working memory, while those that suppress TRPC channels impair it. However, depending on the channel types, areas, and systems tested, this is not the case in all studies. Further work to clarify involvement of specific TRPC channels in working memory tasks and how they are affected by neuromodulators is still necessary in the future. Copyright © 2018 Elsevier B.V.

The arts and humanities have a powerful capacity to create lines of communication between the public, policy and scientific spheres. A growing network of visual and performing artists, writers and scientists has been actively working together since 2007 to integrate scientific and artistic perspectives on climate change in interior Alaska. These efforts have involved field workshops and collaborative creative processes culminating in public performances and a visual art exhibit. The most recent multimedia event was entitled In a Time of Change: Envisioning the Future, and challenged artists and scientists to consider future scenarios of climate change. This event included a public performance featuring original theatre, modern dance, Alaska Native Dance, poetry and music that was presented concurrently with an art exhibit featuring original works by 24 Alaskan visual artists. A related effort targeted K12 students, through an early college course entitled Climate Change and Creative Expression, which was offered to high school students at a predominantly Alaska Native charter school and integrated climate change science, creative writing, theatre and dance. Our program at Bonanza Creek Long Term Ecological Research (LTER) site is just one of many successful efforts to integrate arts and humanities with science within and beyond the NSF LTER Program. The efforts of various LTER sites to engage the arts and humanities with science, the public and policymakers have successfully generated excitement, facilitated mutual understanding, and promoted meaningful dialogue on issues facing science and society. The future outlook for integration of arts and humanities with science appears promising, with increasing interest from artists, scientists and scientific funding agencies.

US agricultural and Govt. lands have a unique co-dependent relationship, particularly in the Western US. More than 30% of all irrigated US agricultural output comes from lands sustained by the Ogallala Aquifer in the western Great Plains. Six US Forest Service National Grasslands reside within the aquifer region, consisting of over 375,000 ha (3,759 km2) of USFS managed lands. Likewise, National Forest lands are the headwaters to many intensive agricultural regions. Our Ogallala Aquifer team is enhancing crop irrigation decision tools with predictive weather and remote sensing data to better manage water for irrigated crops within these regions. An integrated multi-model software framework is used to link irrigation decision tools, resulting in positive management benefits on natural water resources. Teams and teams-of-teams can build upon these multi-disciplinary multi-faceted modeling capabilities. For example, the CSU Catalyst for Innovative Partnerships program has formed a new multidisciplinary team that will address "Rural Wealth Creation" focusing on the many integrated links between economic, agricultural production and management, natural resource availabilities, and key social aspects of govt. policy recommendations. By enhancing tools like these with predictive weather and other related data (like in situ measurements, hydrologic models, remotely sensed data sets, and (in the near future) linking to agro-economic and life cycle assessment models) this work demonstrates an integrated data-driven future vision of inter-meshed dynamic systems that can address challenging multi-system problems. We will present the present state of the work and opportunities for future involvement.

Class Explorations in Space: From the Blackboard and History to the Outdoors and Future

NASA Astrophysics Data System (ADS)

Our everyday activities occur so seamlessly in the space around us as to leave us unawares of space, its properties, and our use of it. What might we notice, wonder about and learn through interacting with space exploratively? My seminar class took on that question as an opening for personal and group experiences during this semester. In the process, they observe space locally and in the sky, read historical works of science involving space, and invent and construct forms in space. All these actions arise responsively, as we respond to: physical materials and space; historical resources; our seminar participants, and future learners. Checks, revisions and further developments -- on our findings, geometrical constructions, shared or personal inferences---come about observationally and collaboratively. I teach this seminar as an expression of the research pedagogy of critical exploration, developed by Eleanor Duckworth from the work of Jean Piaget, B"arbel Inhelder and the Elementary Science Study. This practice applies the quest for understanding of a researcher to spontaneous interactions evolving within a classroom. The teacher supports students in satisfying and developing their curiosities, which often results in exploring the subject matter by routes that are novel to both teacher and student. As my students ``mess about'' with geometry, string and chalk at the blackboard, in their notebooks, and in response to propositions in Euclid's Elements, they continually imagine further novel venues for using geometry to explore space. Where might their explorations go in the future? I invite you to hear from them directly!

2002-04-01

This paper presents findings from a multimethod evaluation of an interprofessional training ward placement for medical, nursing, occupational therapy and physiotherapy students. Unique in the UK, and following the pioneering work at Linköping, the training ward allowed senior pre-qualification students, under the supervision of practitioners, to plan and deliver interprofessional care for a group of orthopaedic and rheumatology patients. This responsibility enabled students to develop profession-specific skills and competencies in dealing with patients. It also allowed them to enhance their teamworking skills in an interprofessional environment. Student teams were supported by facilitators who ensured medical care was optimal, led reflective sessions and facilitated students' problem solving. Data were collected from all groups of participants involved in the ward: students, facilitators and patients. Methods included questionnaires, interviews and observations. Findings are presented from each participating group, with a particular emphasis placed on the perspective of medicine. The study found that students valued highly the experiential learning they received on the ward and felt the ward prepared them more effectively for future practice. However, many encountered difficulties adopting an autonomous learning style during their placement. Despite enjoying their work on the ward, facilitators were concerned that the demands of their role could result in 'burn-out'. Patients enjoyed their ward experience and scored higher on a range of satisfaction indicators than a comparative group of patients. Participants were generally positive about the training ward. All considered that it was a worthwhile experience and felt the ward should recommence in the near future.

Action-Specific Influences on Perception and Post-Perceptual Processes: Present Controversies and Future Directions

PubMed Central

Philbeck, John W.; Witt, Jessica K.

2015-01-01

The action-specific perception account holds that people perceive the environment in terms of their ability to act in it. In this view, for example, decreased ability to climb a hill due to fatigue makes the hill visually appear to be steeper. Though influential, this account has not been universally accepted, and in fact a heated controversy has emerged. The opposing view holds that action capability has little or no influence on perception. Heretofore, the debate has been quite polarized, with efforts largely being focused on supporting one view and dismantling the other. We argue here that polarized debate can impede scientific progress and that the search for similarities between two sides of a debate can sharpen the theoretical focus of both sides and illuminate important avenues for future research. In this paper, we present a synthetic review of this debate, drawing from the literatures of both approaches, to clarify both the surprising similarities and the core differences between them. We critically evaluate existing evidence, discuss possible mechanisms of action-specific effects, and make recommendations for future research. A primary focus of future work will involve not only the development of methods that guard against action-specific post-perceptual effects, but also development of concrete, well-constrained underlying mechanisms. The criteria for what constitutes acceptable control of post-perceptual effects and what constitutes an appropriately specific mechanism vary between approaches, and bridging this gap is a central challenge for future research.

Changes in the shoreline at Paradip Port, India in response to climate change

NASA Astrophysics Data System (ADS)

Gopikrishna, B.; Deo, M. C.

2018-02-01

One of the popular methods to predict shoreline shifts into the future involves use of a shoreline evolution model driven by the historical wave climate. It is however understood by now that historical wave conditions might substantially change in future in response to climate change induced by the global warming. The future shoreline changes as well as sediment transport therefore need to be determined with the help of future projections of wave climate. In this work this is done at the port of Paradip situated along the east coast of India. The high resolution wind resulting from a climate modelling experiment called: CORDEX, South Asia, was used to simulate waves over two time-slices of 25 years each in past and future. The wave simulations were carried out with the help of a numerical wave model. Thereafter, rates of longshore sediment transport as well as shoreline shifts were determined over past and future using a numerical shoreline model. It was found that at Paradip Port the net littoral drift per metre width of cross-shore might go up by 37% and so also the net accumulated drift over the entire cross-shore width by 71%. This could be caused by an increase in the mean significant wave height of around 32% and also by changes in the frequency and direction of waves. The intensification of waves in turn might result from an increase in the mean wind speed of around 19%. Similarly, the horizontal extent of the beach accretion and erosion at the port's southern breakwater might go up by 4 m and 8 m, respectively, from the current level in another 25 years. This study should be useful in framing future port management strategies.

Professional boundary work in the face of change to generalist working in community nursing in Scotland.

PubMed

Gray, Carol; Hogg, Rhona; Kennedy, Catriona

2011-08-01

The present study explored how community nurses and managers constituted changes towards generalist working. Following international trends moving from acute care towards community care, changes within community nursing in the United Kingdom have been subject to debate in recent years. Sociological insights into 'boundary work' in professional disciplines are informative for understandings about proposed new roles in community nursing. Recently, radical changes to the role of the community nurse from specialist disciplines to a generalist community health nurse model were proposed in Scotland and tested in four health boards. Focus group discussions were held with 27 community nurses and semi-structured interviews with three managers during January-March 2009 in a purposive sample from one health board. Discussions were audio-recorded and transcribed verbatim. Initial thematic analysis was used to highlight key themes from the data and later a discursive analysis focused on the rhetorical strategies used by participants. Four key themes were identified along with the rhetorical devices associated with these including: the undermining of the generalist model through the 'jack of all trades, master of none' metaphor through associations of loss of specialisms; how the re-establishment of specialist discipline boundaries occurred; how current roles were validated and how managers and nurses accounted for future changes to the profession. The qualitative study explored here has implications for discussions about future role change debates within community nursing as well as the specialist-generalist debate internationally. Managers and policy-makers involved in organizational changes are required to give greater credence to the perceived professional status of community nursing. © 2011 The Authors.

Biodiversity conservation in Swedish forests: ways forward for a 30-year-old multi-scaled approach.

PubMed

Gustafsson, Lena; Perhans, Karin

2010-12-01

A multi-scaled model for biodiversity conservation in forests was introduced in Sweden 30 years ago, which makes it a pioneer example of an integrated ecosystem approach. Trees are set aside for biodiversity purposes at multiple scale levels varying from individual trees to areas of thousands of hectares, with landowner responsibility at the lowest level and with increasing state involvement at higher levels. Ecological theory supports the multi-scaled approach, and retention efforts at every harvest occasion stimulate landowners' interest in conservation. We argue that the model has large advantages but that in a future with intensified forestry and global warming, development based on more progressive thinking is necessary to maintain and increase biodiversity. Suggestions for the future include joint planning for several forest owners, consideration of cost-effectiveness, accepting opportunistic work models, adjusting retention levels to stand and landscape composition, introduction of temporary reserves, creation of "receiver habitats" for species escaping climate change, and protection of young forests.

Exploring women community college natural scientists' personal experience narratives through a subjectivist lens

NASA Astrophysics Data System (ADS)

Woods, Nancy Anne

The thrust in education today is to encourage young women to enter nontraditional fields of study such as chemistry, physics, and biology. In order to better prepare the next generation of women scientists, then, we should examine the experiences of women participants already working within these areas. We can learn from their experiences. What motivated them toward science? What influenced them to become teachers? What brought them to the community college? If the premise is that we want more women involved in science, then one way to understand how to entice women into science would be to research those who are already there. This research project has two important findings, (1) women community college natural science instructors can experience issues of identity between their roles as scientists and teachers; (2) women community college natural science instructors value a different community structure compared to many of their male counterparts. This research lists several recommendations for future practice as well as recommendations for future research.

The future of almanac services --- an HMNAO perspective

2015-08-01

This talk will explore the means for delivering almanac data currently under consideration by HM Nautical Almanac Office in the near to medium future. While there will be a need to continue printed almanacs, almanac data must be available in a variety of forms ranging from paper almanacs to traditional web services through to applications for mobile devices and smartphones. The supply of data using applications may call for a different philosophy in supplying ephemeris data, one that differentiates between an application that calls on a web server for its data and one that has built-in ephemerides. These ephemerides need to be of a reasonably high precision while maintaining a modest machine footprint. These services also need to provide a wide range of applications ranging from traditional sunrise/set data though to more specialized services such as celestial navigation. The work necessary to meet these goals involves efficient programming, intuitive user interfaces, compact and efficient ephemerides and a suitable range of tools to meet the user's needs.

The IOM report on the future of nursing: what perioperative nurses need to know.

PubMed

Battié, Renae N

2013-09-01

The 2010 Institute of Medicine (IOM) report, The Future of Nursing: Leading Change, Advancing Health, continues to be the most-viewed report in IOM history. Nearly three years after its publication, there are action coalitions of nursing and non-nursing agencies in 50 states and the District of Columbia collaborating to move the eight recommendations for action forward. There is much work to do to reshape health care delivery in the United States, and the IOM has identified nurses as key leaders in driving the reform. Every nurse must be educated on the key messages of the IOM report and become involved in moving these recommendations forward as well as in educating others on what needs to be done. AORN and perioperative nurses have a key role in voicing the unique needs of perioperative patients and in ensuring that perioperative patient care is represented in reform activities.

The goals of this research endeavor have been to develop a flexible and relatively complete framework for the investigation of current and future satellite data sources in numerical meteorology. In order to realistically model how satellite information might be used for these purposes, it is necessary that Observing System Simulation Experiments (OSSEs) be as complete as possible. It is therefore desirable that these experiments simulate in entirety the sequence of steps involved in bringing satellite information from the radiance level through product retrieval to a realistic analysis and forecast sequence. In this project we have worked to make this sequence realistic by synthesizing raw satellite data from surrogate atmospheres, deriving satellite products from these data and subsequently producing analyses and forecasts using the retrieved products. The accomplishments made in 1991 are presented. The emphasis was on examining atmospheric soundings and microphysical products which we expect to produce with the launch of the Advanced Microwave Sounding Unit (AMSU), slated for flight in mid 1994.

Producing detailed forms of design documentation, such as pseudocode and structured flowcharts, to describe the procedures of a software system:(1) allows software developers to model and discuss their understanding of a problem and the design of a solution free from the syntax of a programming language,(2) facilitates deeper involvement of non-technical stakeholders, such as the customer or project managers, whose influence ensures the quality, correctness and timeliness of the resulting system,(3) forms comprehensive documentation of the system for its future maintenance, reuse and/or redeployment.However, such forms of documentation require effort to create and maintain.This paper describes a software tool which is currently being developed within the Space Systems Research Group at the University of Dundee which aims to improve the utility of, and the incentive for, creating detailed design documentation for the procedures of a software system. The rationale for creating such a tool is briefly discussed, followed by a description of the tool itself, a summary of its perceived benefits, and plans for future work.

Future Mars missions require new capabilities that currently are not available. The Mars Technology Program (MTP) is an integral part of the Mars Exploration Program (MEP). Its sole purpose is to assure that required technologies are developed in time to enable the baselined and future missions. The MTP is a NASA-wide technology development program managed by JPL. It is divided into a Focused Program and a Base Program. The Focused Program is tightly tied to the proposed Mars Program mission milestones. It involves time-critical deliverables that must be developed in time for infusion into the proposed Mars 2005, and, 2009 missions. In addition a technology demonstration mission by AFRL will test a LIDAR as part of a joint NASNAFRL experiment. This program bridges the gap between technology and projects by vertically integrating the technology work with pre-project development in a project-like environment with critical dates for technology infusion. A Base Technology Program attacks higher riskhigher payoff technologies not in the critical path of missions.

The progress of technology and the global integration of our economic and security infrastructures have introduced vulnerabilities to space weather that demand a more comprehensive ability to specify and to predict the dynamics of the space environment. This requires a comprehensive network of real-time space-based and ground-based observations with long-term continuity. In order to determine the most cost effective space architectures for NOAA's weather, space weather, and environmental missions, NOAA conducted the NOAA Satellite Observing System Architecture (NSOSA) study. This presentation will summarize the process used to document the future needs and the relative priorities for NOAA's operational space-based observations. This involves specifying the most important observations, defining the performance attributes at different levels of capability, and assigning priorities for achieving the higher capability levels. The highest priority observations recommended by the Space Platform Requirements Working Group (SPRWG) for improvement above a minimal capability level will be described. Finally, numerous possible satellite architectures have been explored to assess the costs and benefits of various architecture configurations.

Requirements for new technologies in the area of civil aircraft design are mainly related to the high cost involved in the purchase of modern, fuel saving aircraft. A second important factor is the long term rise in the price of fuel. The demonstration of the benefits of new technologies, as far as these are related to aerodynamics, will,for the foreseeable future, still be based on wind tunnel measurements. Theoretical computation methods are very successfully used in design work, wing optimization, and an estimation of the Reynolds number effect. However, wind tunnel tests are still needed to verify the feasibility of the considered concepts. Along with other costs, the cost for the wind tunnel tests needed for the development of an aircraft is steadily increasing. The present investigation is concerned with the effect of numerical aerodynamics and civil aircraft technology on the development of wind tunnels. Attention is given to the requirements for the wind tunnel, investigative methods, measurement technology, models, and the relation between wind tunnel experiments and theoretical methods.

Carbon nanomaterials (CNMs) have attracted increasing attention due to their unique electrical, optical, thermal, mechanical and chemical properties. CNMs are extensively applied in electronic, optoelectronic, photovoltaic and sensing devices fields, especially in bioassay technology. These excellent properties significantly depend on not only the functional atomic structures of CNMs, but also the interactions with other materials, such as gold nanoparticles, SiO2, chitosan, etc. This review systematically summarizes applications of CNMs in electrochemical aptasensors (ECASs). Firstly, definition and development of ECASs are introduced. Secondly, different ways of ECASs about working principles, classification and construction of CNMs are illustrated. Thirdly, the applications of different CNMs used in ECASs are discussed. In this review, different types of CNMs are involved such as carbon nanotubes, graphene, graphene oxide, etc. Besides, the newly emerging CNMs and CNMs-based composites are also discoursed. Finally, we demonstrate the future prospects of CNMs-based ECASs, and some suggestions about the near future development of CNMs-based ECASs are highlighted. Copyright © 2015 Elsevier B.V.

Although growing evidence has shown that remembering the past and imagining the future recruit a common core network of frontal-parietal-temporal regions, the extent to which these regions contribute to the temporal dimension of autobiographical thought remains unclear. In this fMRI study, we focused on the event-sequencing aspect of time and examined whether ordering past and future events involve common neural substrates. Participants had to determine which of two past (or future) events occurred (or would occur) before the other, and these order judgments were compared with a task requiring to think about the content of the same past or future events. For both past and future events, we found that the left posterior hippocampus was more activated when establishing the order of events, whereas the anterior hippocampus was more activated when representing their content. Aside from the hippocampus, most of the brain regions that were activated when thinking about temporal order (notably the intraparietal sulcus, dorsolateral pFC, dorsal anterior cingulate, and visual cortex) lied outside the core network and may reflect the involvement of controlled processes and visuospatial imagery to locate events in time. Collectively, these findings suggest (a) that the same processing operations are engaged for ordering past events and planned future events in time, (b) that anterior and posterior portions of the hippocampus are involved in processing different aspects of autobiographical thought, and (c) that temporal order is not necessarily an intrinsic property of memory or future thought but instead requires additional, controlled processes.

The promotion of a sustainable, healthy and productive working life attracts more and more attention. Recently the Work Role Functioning Questionnaire (WRFQ) has been cross-culturally translated and adapted to Dutch. This questionnaire aims to measure the health-related work functioning of workers with health problems. The aim of this study is to evaluate the reliability, validity (including five new items) and responsiveness of the WRFQ 2.0 in the working population. A longitudinal study was conducted among workers. The reliability (internal consistency, test-retest reliability, measurement error), validity (structural validity-factor analysis, construct validity by means of hypotheses testing) and responsiveness of the WRFQ 2.0 were evaluated. A total of N = 553 workers completed the survey. The final WRFQ 2.0 has four subscales and showed very good internal consistency, moderate test-retest reliability, good construct validity and moderate responsiveness in the working population. The WRFQ was able to distinguish between groups with different levels of mental health, physical health, fatigue and need for recovery. A moderate correlation was found between WRFQ and related constructs respectively work ability and work productivity. A weak relationship was found with general self-rated health, work engagement and work involvement. The WRFQ 2.0 is a reliable and valid instrument to measure health-related work functioning in the working population. Further validation in larger samples is recommended, especially for test-retest reliability, responsiveness and the questionnaire's ability to predict the future course of health-related work functioning.

Within the care of people living with respiratory conditions, nursing, physiotherapy, and respiratory therapy healthcare professionals routinely work in interprofessional teams. To help students prepare for their future professional roles, there is a need for them to be involved in interprofessional education. The purpose of this project was to compare two different methods of patient simulation in improving interprofessional competencies for students in nursing, physiotherapy, and respiratory therapy programmes. The Canadian Interprofessional Health Collaborative competencies of communication, collaboration, conflict resolution patient/family-centred care, roles and responsibilities, and team functioning were measured. Using a quasi-experimental pre-post intervention approach two different interprofessional workshops were compared: the combination of standardised and simulated patients, and exclusively standardised patients. Students from nursing, physiotherapy, and respiratory therapy programmes worked together in these simulation-based activities to plan and implement care for a patient with a respiratory condition. Key results were that participants in both years improved in their self-reported interprofessional competencies as measured by the Interprofessional Collaborative Competencies Attainment Survey (ICCAS). Participants indicated that they found their interprofessional teams did well with communication and collaboration. But the participants felt they could have better involved the patients and their family members in the patient's care. Regardless of method of patient simulation used, mannequin or standardised patients, students found the experience beneficial and appreciated the opportunity to better understand the roles of other healthcare professionals in working together to help patients living with respiratory conditions.

As research is being performed for the new heat shield for the Orion capsule, National Aeronautics and Space Administration (NASA) is developing the first composite heat shield. As an intern of the Structures Branch in the Engineering Directorate (ES 2), my main task was to set up a test plan to determine the material properties of the honeycomb that will be used on the Orion Crew Module heat shield to verify that the composite is suitable for the capsule. Before conducting composite shell tests, which are performed to simulate the crush performance of the heat shield on the capsule, it is necessary to determine the compression and shear properties of the composite used on the shell. During this internship, I was responsible for developing a test plan, designing parts for the test fixtures as well as getting them fabricated for the honeycomb shear and compression testing. This involved work in Pro/Engineer as well as coordinating with Fab Express, the Building 9 Composite Shop and the Structures Test Laboratory (STL). The research and work executed for this project will be used for composite sandwich panel testing in the future as well. As a part of the Structures Branch, my main focus was to research composite structures. This involves system engineering and integration (SE&I) integration, manufacturing, and preliminary testing. The procedures for these projects that were executed during this internship included design work, conducting tests and performing analysis.

Nuclear emergency management procedures in Europe

NASA Astrophysics Data System (ADS)

Carter, Emma

The Chernobyl accident brought to the fore the need for decision-making in nuclear emergency management to be transparent and consistent across Europe. A range of systems to support decision-making in future emergencies have since been developed, but, by and large, with little consultation with potential decision makers and limited understanding of the emergency management procedures across Europe and how they differ. In nuclear emergency management, coordination, communication and information sharing are of paramount importance. There are many key players with their own technical expertise, and several key activities occur in parallel, across different locations. Business process modelling can facilitate understanding through the representation of processes, aid transparency and structure the analysis, comparison and improvement of processes. This work has been conducted as part of a European Fifth Framework Programme project EVATECH, whose aim was to improve decision support methods, models and processes taking into account stakeholder expectations and concerns. It has involved the application of process modelling to document and compare the emergency management processes in four European countries. It has also involved a multidisciplinary approach taking a socio-technical perspective. The use of process modelling did indeed facilitate understanding and provided a common platform, which was not previously available, to consider emergency management processes. This thesis illustrates the structured analysis approach that process modelling enables. Firstly, through an individual analysis for the United Kingdom (UK) model that illustrated the potential benefits for a country. These are for training purposes, to build reflexive shared mental models, to aid coordination and for process improvement. Secondly, through a comparison of the processes in Belgium, Germany, Slovak Republic and the UK. In this comparison of the four processes we observed that the four process models are substantially different in their organisational structure and identified differences in the management of advice, where decisions are made and the communication network style. Another key aspect of this work is that through the structured analysis conducted we were able to develop a framework for the evaluation of DSS from the perspective of process. This work concludes reflecting on the challenges, which the European off-site nuclear emergency community face and suggest direction for future work, with particular reference to a recent conference on the capabilities and challenges of offsite nuclear emergency management, the Salzburg Symposium 2003.

Support of an Active Science Project by a Large Information System: Lessons for the EOS Era

The ability of large information systems to support the changing data requirements of active science projects is being tested in a NASA collaborative study. This paper briefly profiles both the active science project and the large information system involved in this effort and offers some observations about the effectiveness of the project support. This is followed by lessons that are important for those participating in large information systems that need to support active science projects or that make available the valuable data produced by these projects. We learned in this work that it is difficult for a large information system focused on long term data management to satisfy the requirements of an on-going science project. For example, in order to provide the best service, it is important for all information system staff to keep focused on the needs and constraints of the scientists in the development of appropriate services. If the lessons learned in this and other science support experiences are not applied by those involved with large information systems of the EOS (Earth Observing System) era, then the final data products produced by future science projects may not be robust or of high quality, thereby making the conduct of the project science less efficacious and reducing the value of these unique suites of data for future research.
