Do Biology Majors Really Differ from Non–STEM Majors?

PubMed Central

Cotner, Sehoya; Thompson, Seth; Wright, Robin

2017-01-01

Recent calls to action urge sweeping reform in science education, advocating for improved learning for all students—including those majoring in fields beyond the sciences. However, little work has been done to characterize the differences—if any exist—between students planning a career in science and those studying other disciplines. We describe an attempt to clarify, in broad terms, how non–STEM (science, technology, engineering, and mathematics) majors differ from life sciences majors, and how they are similar. Using survey responses and institutional data, we find that non–STEM majors are not unilaterally science averse; non–STEM majors are more likely than biology majors to hold misconceptions about the nature of science, yet they are not completely ignorant of how science works; non–STEM majors are less likely than biology majors to see science as personally relevant; and non–STEM majors populations are likely to be more diverse—with respect to incoming knowledge, perceptions, backgrounds, and skills—than a biology majors population. We encourage science educators to consider these characteristics when designing curricula for future scientists or simply for a well-informed citizenry. PMID:28798210

High-dependency care: experiences of the psychosocial work environment.

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

Smith, David W.; Vandergaast, Gary; Sungaila, Mark

2013-07-01

The Port Granby Project is an integral part of the Port Hope Area Initiative (PHAI), and is located approximately 14 kilometres west of the Municipality of Port Hope in the adjacent Municipality of Clarington, Ontario. The principal objective of the project is the excavation and relocation of low-level radioactive waste (LLRW) and marginally contaminated soils, which were deposited at the Port Granby Waste Management Facility (PGWMF) by Eldorado Nuclear Limited during the period 1955 to 1988, to a new, highly engineered above-ground Long-term Waste Management Facility (LTWMF) to be constructed on a nearby site. The Environmental Assessment for the Projectmore » was approved in 2009 August and the required Waste Nuclear Substance License was received in 2011 November. Once the detailed engineering design was completed, in 2011 March, the Port Granby Project was divided into three major contracts for construction implementation purposes. The first of these contracts was completed in late 2012 and the second is planned to start in early 2013. The contracting process for the third major contract is also expected to be completed during 2013. This paper provides an overview of the Port Granby Project as well as discussion on the status of the Project, including the regulatory approvals process, the approach to contracting the construction works and an update of work recently completed and soon to get underway.

The main purpose of this grant proposal was to fund the ongoing work on brown dwarfs by Denise Stephens during her tenure at STScI as a postdoctoral researcher. We have completed approximately half of the three-year grant period. Dr. Stephens has now assumed to role of senior research associate at Johns Hopkins University and in this position is eligible to be PI of grants. Because the bulk of the work and funds under this grant have been and will continue to be for the purposes of supporting Dr. Stephens, we are transferring control of the grant to her at JHU. This closeout is a formality to allow that transfer. The largest project was the completion of a major work on the infrared photometry of L and T dwarfs. The paper was published in January 2004.

2010-08-01

To investigate the relationships between workplace psychosocial factors, work/family conflicts, depression, and health-related presenteeism in a sample of employees who were randomly selected from the communities. A cross-sectional study of 4032 employees representative of the working population aged 25 to 64 years in Alberta, Canada. Data about workplace characteristics, depression, and health-related presenteeism were collected through telephone. In the participants, 47.3% and 42.9% reported some degree of impaired job performance in completing work and avoiding distraction, respectively. Major depression is the strongest factor associated with avoiding distraction. Job strain and effort-reward imbalance seemed to affect job performance through severity of depression but not major depression. Negative work environment may directly and indirectly affect job performance. Workplace health promotion activities should target organizational factors such as job strain and effort-reward imbalance and work/family conflicts so as to reduce the risk of depression and the direct and indirect effects of these risk factors and depression on productivity.

Depression is reported to be a major cause of illness-related sub-optimal work performance (presenteeism). However, the majority of studies examining presenteeism have relied on self-report measures of work performance. Furthermore, employers currently face a number of practical challenges in attempting to facilitate early identification of depression. To test whether a web-based screening tool for depression could be used successfully in the workplace and whether it was possible to detect an association between rates of depression and objective measures of impaired workgroup performance. All permanent employees of a telecommunications company with UK-based call centres were encouraged to complete a web-based psychological assessment using the Patient Health Questionnaire depression scale (PHQ-9). In addition to confidential individual level results, the tool was able to provide anonymized summary statistics for each workgroup. Four objective measures of work performance were collected for each workgroup. During the study period, 1161 web-based PHQ-9 questionnaires were completed. There was a negative linear relationship between rates of depressive symptoms and the overall performance of a workgroup (P < 0.001). The linear relationship between depression and workgroup performance remained after controlling for gender balance, percent of temporary staff, employees' perceived level of engagement and satisfaction with their line manager (P < 0.01). Workgroups with high levels of depressive symptoms tend to perform poorly. Computer-aided web-based screening for symptoms of depression is feasible in a work setting.

"The only way I know how to live is to work": a qualitative study of work following treatment for prostate cancer.

Grunfeld, Elizabeth A; Drudge-Coates, Lawrence; Rixon, Lorna; Eaton, Emma; Cooper, Alethea F

2013-01-01

For many survivors of prostate cancer, returning to work posttreatment is a realistic goal. However, little research to date has explored work among prostate cancer survivors. The focus of this study was to explore the meaning of work among prostate cancer survivors and to describe the linkages between masculinity and work following prostate cancer treatment. Fifty prostate cancer survivors who were in paid employment prior to their diagnosis completed a semistructured interview following completion of their treatment and of these, 41 also completed a 12-month follow-up interview. Framework analysis of the 91 transcripts was undertaken. The majority of the men had returned to work at the 12-month interview. Four themes were identified, and these were labeled "Work and self-identity," "Work-related implications of treatment side effects," "Disclosure of cancer," and "Perceptions of future as a cancer survivor." A degree of embarrassment and concern about residual side effects and whether these would present a challenge within the workplace was apparent among our sample and was compounded by a reluctance to disclose these. The descriptions provided by the men in this study reveal that the experience of prostate cancer can lead to challenges for both social and work-related roles. The influence of prostate cancer on men's reports of masculinity was variable, and recognition of these differences is required. In addition, some survivors of prostate cancer may require specific interventions aimed at helping them to manage disclosure of their illness, particularly within a work environment.

Progress in Decommissioning the Humboldt Bay Power Plant - 13604

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

Rod, Kerry; Shelanskey, Steven K.; Kristofzski, John

Decommissioning of the Pacific Gas and Electric (PG and E) Company Humboldt Bay Power Plant (HBPP) Unit 3 nuclear facility has now, after more than three decades of SAFSTOR and initial decommissioning work, transitioned to full-scale decommissioning. Decommissioning activities to date have been well orchestrated and executed in spite of an extremely small work site with space constricted even more by other concurrent on-site major construction projects including the demolition of four fossil units, construction of a new generating station and 60 KV switchyard upgrade. Full-scale decommissioning activities - now transitioning from Plant Systems Removal (PG and E self-perform) tomore » Civil Works Projects (contractor performed) - are proceeding in a safe, timely, and cost effective manner. As a result of the successful decommissioning work to date (approximately fifty percent completed) and the intense planning and preparations for the remaining work, there is a high level of confidence for completion of all HBPP Unit 3 decommissions activities in 2018. Strategic planning and preparations to transition into full-scale decommissioning was carried out in 2008 by a small, highly focused project team. This planning was conducted concurrent with other critical planning requirements such as the loading of spent nuclear fuel into dry storage at the Independent Spent Fuel Storage Installation (ISFSI) finishing December 2008. Over the past four years, 2009 through 2012, the majority of decommissioning work has been installation of site infrastructure and removal of systems and components, known as the Plant System Removal Phase, where work scope was dynamic with significant uncertainty, and it was self-performed by PG and E. As HBPP Decommissioning transitions from the Plant System Removal Phase to the Civil Works Projects Phase, where work scope is well defined, a contracting plan similar to that used for Fossil Decommissioning will be implemented. Award of five major work scopes in various stages of development are planned as they include: Turbine Building Demolition, Nuclear Facilities Demolition and Excavation, Intake and Discharge Canal Remediation, Office Facility Demobilization, and Final Site Restoration. Benefits realized by transitioning to the Civil Works Projects Phase with predominant firm fixed-price/fixed unit price contracting include single civil works contractor who can coordinate concrete shaving, liner removal, structural removal, and other demolition activities; streamline financial control; reduce PG and E overhead staffing; and provide a specialized Bidder Team with experience from other similar projects.

Where do Students Go Wrong in Applying the Scientific Method?

NASA Astrophysics Data System (ADS)

Rubbo, Louis; Moore, Christopher

2015-04-01

Non-science majors completing a liberal arts degree are frequently required to take a science course. Ideally with the completion of a required science course, liberal arts students should demonstrate an improved capability in the application of the scientific method. In previous work we have demonstrated that this is possible if explicit instruction is spent on the development of scientific reasoning skills. However, even with explicit instruction, students still struggle to apply the scientific process. Counter to our expectations, the difficulty is not isolated to a single issue such as stating a testable hypothesis, designing an experiment, or arriving at a supported conclusion. Instead students appear to struggle with every step in the process. This talk summarizes our work looking at and identifying where students struggle in the application of the scientific method. This material is based upon work supported by the National Science Foundation under Grant No. 1244801.

The purpose of this study was to analyze characteristics of individuals working in the profession of neuropsychology in Latin America in order to understand their background, professional training, current work situation, assessment and diagnostic procedures used, rehabilitation techniques employed, population targeted, teaching responsibilities, and research activities. A total of 808 professionals working in neuropsychology from 17 countries in Latin America completed an online survey between July 2013 and January 2014. The majority of participants were female and the mean age was 36.76 years (range 21-74 years). The majority of professionals working in neuropsychology in Latin America have a background in psychology, with some additional specialized training and supervised clinical practice. Over half work in private practice, universities, or private clinics and are quite satisfied with their work. Those who identify themselves as clinicians primarily work with individuals with learning problems, ADHD, mental retardation, TBI, dementia, and stroke. The majority respondents cite the top barrier in the use of neuropsychological instruments to be the lack of normative data for their countries. The top perceived barriers to the field include: lack of academic training programs, lack of clinical training opportunities, lack of willingness to collaborate between professionals, and lack of access to neuropsychological instruments. There is a need in Latin America to increase regulation, improve graduate curriculums, enhance existing clinical training, develop professional certification programs, validate existing neuropsychological tests, and create new, culturally-relevant instruments.

Implementation of primary care has long been a priority in low- and middle-income countries. Violence at work may hamper progress in this field. Hence, we examined the associations between violence at work and depressive symptoms/major depression in primary care teams (physicians, nurses, nursing assistants, and community health workers). A cross-sectional study was undertaken in the city of Sao Paulo, Brazil. We assessed a random sample of Family Health Program teams. We investigated depressive symptoms and major depression using the nine-item Patient Health Questionnaire (PHQ-9), and exposure to violence at work in the previous 12 months using a standardized questionnaire. Associations between exposure to violence and depressive symptoms/major depression were analyzed using multinomial logistic regression. Of 3141 eligible workers, 2940 (93 %) completed the interview. Of these, 36.3 % (95 % CI 34.6-38.1) presented intermediate depressive symptoms, and 16 % (95 % CI 14.6-17.2), probable major depression. The frequencies of exposure to the different types of violence at work were: insults (44.9 %), threats (24.8 %), physical aggression (2.3 %), and witnessing violence (29.5 %). These exposures were strongly and progressively associated with depressive symptoms (adjusted odds ratio 1.67 for exposure to one type of violence; and 5.10 for all four types), and probable major depression (adjusted odds ratio 1.84 for one type; and 14.34 for all four types). Primary care workers presenting depressive symptoms and those who have experienced violence at work should be assisted. Policy makers should prioritize strategies to prevent these problems, since they can threaten primary care sustainability.

Sidnie Manton became best known for her work on arthropod locomotion, and for proposing radical views on the evolution of arthropods that were accepted for a generation. However, her early training was as an embryologist, and the work that she carried out at the beginning of her career still stands as one of the major twentieth century contributions to the study of crustacean embryology. Here, I review her first major paper, largely completed while she was a graduate student, describing embryonic development in Hemimysis lamornae, a small shrimp-like animal found in the seas around the UK. The clarity of her writing and the quality of her figures set a standard that laid the basis for subsequent work, and although not all of her conclusions have stood the test of time, they remain a standard reference for work today. This commentary was written to celebrate the 350th anniversary of the journal Philosophical Transactions of the Royal Society.

Abstract Background Working Health Service Scotland (WHSS) supports the self-employed and employees of small and medium-sized enterprises (SMEs) in Scotland with a health condition affecting their ability to work, who are either absent or at risk of becoming absent due to it. Aims To evaluate the impact on health and work outcomes of WHSS clients over a 4-year period. Methods Data were collected at enrolment, entry, discharge and follow-up at 3 and 6 months after discharge. Clients completed up to three validated health questionnaires at entry and discharge—EuroQol five dimensions (EQ-5D) and visual analogue scale (VAS); Hospital Anxiety and Depression Scale (HADS); and Canadian Occupational Performance Measure (COPM). Results A total of 13463 referrals occurred in the 4-year period; 11748 (87%) were eligible and completed entry assessment and 60% of the latter completed discharge paperwork. The majority of referrals were due to musculoskeletal conditions (84%) while 12% were referred with mental health conditions. Almost a fifth (18%) of cases were absent at entry and back at work at discharge. Work days lost while in WHSS was associated with age, length of absence prior to entering WHSS, primary health condition and time in programme. All health measures showed significant improvements from entry to discharge. Improvement in general health was sustained at 3- and 6-month follow-up. Conclusions The WHSS evaluation findings indicate that participation was associated with positive changes to health and return-to-work. The extent of the positive change in health measures and work ability can be highly important economically for employees and employers. PMID:29390161

Cultivation mode research of practical application talents for optical engineering major

NASA Astrophysics Data System (ADS)

Liu, Zhiying

2017-08-01

The requirements on science and technology graduates are more and higher with modern science progress and society market economy development. Because optical engineering major is with very long practicality, practice should be paid more attention from analysis of optical engineering major and students' foundation. To play role of practice to a large amount, the practice need be systemic and correlation. It should be combination of foundation and profundity. Modern foundation professional knowledge is studied with traditional optical concept and technology at the same time. Systemic regularity and correlation should be embodied in the contents. Start from basic geometrical optics concept, the optical parameter of optical instrument is analyzed, the optical module is built and ray tracing is completed during geometrical optics practice. With foundation of primary aberration calculation, the optical system is further designed and evaluated during optical design practice course. With the optical model and given instrument functions and requirements, the optical-mechanism is matched. The accuracy is calculated, analyzed and distributed in every motion segment. And the mechanism should guarantee the alignment and adjustment. The optical mechanism is designed during the instrument and element design practice. When the optical and mechanism drawings are completed, the system is ready to be fabricated. Students can complete grinding, polishing and coating process by themselves through optical fabricating practice. With the optical and mechanical elements, the system can be assembled and aligned during the thesis practice. With a set of correlated and logical practices, the students can acquire the whole process knowledge about optical instrument. All details are contained in every practice process. These practical experiences provide students working ability. They do not need much adaption anymore when they go to work after graduation. It is favorable to both student talents and employer.

Do Biology Majors Really Differ from Non-STEM Majors?

PubMed

Cotner, Sehoya; Thompson, Seth; Wright, Robin

2017-01-01

Recent calls to action urge sweeping reform in science education, advocating for improved learning for all students-including those majoring in fields beyond the sciences. However, little work has been done to characterize the differences-if any exist-between students planning a career in science and those studying other disciplines. We describe an attempt to clarify, in broad terms, how non-STEM (science, technology, engineering, and mathematics) majors differ from life sciences majors, and how they are similar. Using survey responses and institutional data, we find that non-STEM majors are not unilaterally science averse; non-STEM majors are more likely than biology majors to hold misconceptions about the nature of science, yet they are not completely ignorant of how science works; non-STEM majors are less likely than biology majors to see science as personally relevant; and non-STEM majors populations are likely to be more diverse-with respect to incoming knowledge, perceptions, backgrounds, and skills-than a biology majors population. We encourage science educators to consider these characteristics when designing curricula for future scientists or simply for a well-informed citizenry. © 2017 S. Cotner et al.

2007-09-08

To gather information from senior dental students about their future career plans, with particular emphasis on work-life balance issues, their attitudes towards the NHS and retirement plans. Senior dental students at the Universities of Dundee and Manchester were asked to complete a voluntary anonymous questionnaire. In all 141 questionnaires were completed, 42 by students in Manchester and 114 in Dundee. On qualification nearly all surveyed intend to work full time but after five years one quarter (26%) of females intend to work part time. This is significantly (p < 0.05) different from males where nearly all (98%) intend to work full time. Although the majority (65%) intend to work in general practice significant numbers (19%) wish to have a career in hospital dentistry and very few (3%) in community dentistry. Senior students seem to show no more commitment to the NHS than those in our previous study of dental school applicants. Only 3% intend to work exclusively for the NHS and 18% intend to work exclusively in the private sector. Surprising numbers had plans to retire or go part time before 60 years of age. Only 20% of the sample intended to continue working full time after the age of 60 years. The mode age that those surveyed intended to start a family was 30 years and a large majority of both sexes thought this would interrupt their professional life. More than half of the sample intend to take time out of dentistry until their children attended primary school (female 63%, male 38%) and 6% (female 6%, male 8%) until secondary school. Many of our findings suggest that future generations of dentists may have a pattern of professional life that will have the effect of reducing their clinical commitment, although it is not possible to determine how significant an effect this will have on the workforce. It may, however, be appropriate to take career intention into account when workforce planning.

Quantum thermodynamics of general quantum processes.

Binder, Felix; Vinjanampathy, Sai; Modi, Kavan; Goold, John

2015-03-01

Accurately describing work extraction from a quantum system is a central objective for the extension of thermodynamics to individual quantum systems. The concepts of work and heat are surprisingly subtle when generalizations are made to arbitrary quantum states. We formulate an operational thermodynamics suitable for application to an open quantum system undergoing quantum evolution under a general quantum process by which we mean a completely positive and trace-preserving map. We derive an operational first law of thermodynamics for such processes and show consistency with the second law. We show that heat, from the first law, is positive when the input state of the map majorizes the output state. Moreover, the change in entropy is also positive for the same majorization condition. This makes a strong connection between the two operational laws of thermodynamics.

Determinants of limitations in unpaid work after major trauma: a prospective cohort study with 15 months follow-up.

To identify determinants of limitations in unpaid work (household work, shopping, caring for children and odd jobs around the house) in patients who had suffered major trauma (ISS≥16) and who were in full-time employment (≥80%) at the time of injury. Prospective cohort study. University Medical Centre Utrecht, a level 1 trauma centre in the Netherlands. All severely injured (ISS≥16) adult (age≥16) trauma survivors admitted from January 1999 to December 2000 who were full-time employed at time of the injury were invited for follow-up (n=214). Outcome was assessed with the 'Health and Labour Questionnaire' (HLQ) at a mean of 15 months (SD=1.5) after injury. The HLQ was completed by 211 patients. Response rate was 93%. Logistic regression analyses identified the percentage of permanent impairment (% PI), level of participation (RtW), co-morbidity, lower extremity injury (LEI) and female gender as determinants of limitations in unpaid work. Patients with a post-injury status of part-time or no return to work experienced more limitations in unpaid work than those who returned to full-time employment. Resuming paid work after major trauma is not associated with reductions in unpaid activities. To assess the long-term outcome of rehabilitation programmes, we recommend a measure that combines patient's satisfaction in their post-injury jobs with a satisfactory level of activities in their private lives.

Contrasting single and multi-component working-memory systems in dual tasking.

PubMed

Nijboer, Menno; Borst, Jelmer; van Rijn, Hedderik; Taatgen, Niels

2016-05-01

Working memory can be a major source of interference in dual tasking. However, there is no consensus on whether this interference is the result of a single working memory bottleneck, or of interactions between different working memory components that together form a complete working-memory system. We report a behavioral and an fMRI dataset in which working memory requirements are manipulated during multitasking. We show that a computational cognitive model that assumes a distributed version of working memory accounts for both behavioral and neuroimaging data better than a model that takes a more centralized approach. The model's working memory consists of an attentional focus, declarative memory, and a subvocalized rehearsal mechanism. Thus, the data and model favor an account where working memory interference in dual tasking is the result of interactions between different resources that together form a working-memory system.

Froh, Elizabeth B; Spatz, Diane L

2016-11-01

The Surgeon General's Call to Action to Support Breastfeeding details the need for comprehensive employer lactation support programs. Our institution has an extensive employee lactation program, and our breastfeeding initiation and continuation rates are statistically significantly higher than state and national data, with more than 20% of our employees breastfeeding for more than 1 year. The objective of this research was complete secondary data analysis of qualitative data collected as part of a larger study on breastfeeding outcomes. In the larger study, 545 women who returned to work full or part time completed an online survey with the ability to provide free text qualitative data and feedback regarding their experiences with breastfeeding after return to work. Qualitative data were pulled from the online survey platform. The responses to these questions were analyzed using conventional content analysis by the research team (2 PhD-prepared nurse researchers trained and experienced in qualitative methodologies and 1 research assistant) in order to complete a thematic analysis of the survey data. Analysis of the data yielded 5 major themes: (1) positive reflections, (2) nonsupportive environment/work culture, (3) supportive environment/work culture, (4) accessibility of resources, and (5) internal barriers. The themes that emerged from this research clearly indicate that even in a hospital with an extensive employee lactation program, women have varied experiences-some more positive than others. Returning to work while breastfeeding requires time and commitment of the mother, and a supportive employee lactation program may ease that transition of return to work.

Medication Reconciliation: Work Domain Ontology, prototype development, and a predictive model.

Medication errors can result from administration inaccuracies at any point of care and are a major cause for concern. To develop a successful Medication Reconciliation (MR) tool, we believe it necessary to build a Work Domain Ontology (WDO) for the MR process. A WDO defines the explicit, abstract, implementation-independent description of the task by separating the task from work context, application technology, and cognitive architecture. We developed a prototype based upon the WDO and designed to adhere to standard principles of interface design. The prototype was compared to Legacy Health System's and Pre-Admission Medication List Builder MR tools via a Keystroke-Level Model analysis for three MR tasks. The analysis found the prototype requires the fewest mental operations, completes tasks in the fewest steps, and completes tasks in the least amount of time. Accordingly, we believe that developing a MR tool, based upon the WDO and user interface guidelines, improves user efficiency and reduces cognitive load.

2013-01-01

Over the past two years, through an NSF RCN UBE grant, the ASBMB has held regional workshops for faculty members and science educators from around the country that focused on identifying: 1) core principles of biochemistry and molecular biology, 2) essential concepts and underlying theories from physics, chemistry, and mathematics, and 3) foundational skills that undergraduate majors in biochemistry and molecular biology must understand to complete their major coursework. Using information gained from these workshops, as well as from the ASBMB accreditation working group and the NSF Vision and Change report, the Core Concepts working group has developed a consensus list of learning outcomes and objectives based on five foundational concepts (evolution, matter and energy transformation, homeostasis, information flow, and macromolecular structure and function) that represent the expected conceptual knowledge base for undergraduate degrees in biochemistry and molecular biology. This consensus will aid biochemistry and molecular biology educators in the development of assessment tools for the new ASBMB recommended curriculum. © 2013 by The International Union of Biochemistry and Molecular Biology.

Wide operating window spin-torque majority gate towards large-scale integration of logic circuits

NASA Astrophysics Data System (ADS)

Vaysset, Adrien; Zografos, Odysseas; Manfrini, Mauricio; Mocuta, Dan; Radu, Iuliana P.

2018-05-01

Spin Torque Majority Gate (STMG) is a logic concept that inherits the non-volatility and the compact size of MRAM devices. In the original STMG design, the operating range was restricted to very small size and anisotropy, due to the exchange-driven character of domain expansion. Here, we propose an improved STMG concept where the domain wall is driven with current. Thus, input switching and domain wall propagation are decoupled, leading to higher energy efficiency and allowing greater technological optimization. To ensure majority operation, pinning sites are introduced. We observe through micromagnetic simulations that the new structure works for all input combinations, regardless of the initial state. Contrary to the original concept, the working condition is only given by threshold and depinning currents. Moreover, cascading is now possible over long distances and fan-out is demonstrated. Therefore, this improved STMG concept is ready to build complete Boolean circuits in absence of external magnetic fields.

Psychosocial work factors, major depressive and generalised anxiety disorders: results from the French national SIP study.

Murcia, Marie; Chastang, Jean-François; Niedhammer, Isabelle

2013-04-25

Anxiety and depression are prevalent mental disorders in working populations. The risk factors of these disorders are not completely well known. Developing knowledge on occupational risk factors for mental disorders appears crucial. This study investigates the association between various classical and emergent psychosocial work factors and major depressive and generalised anxiety disorders in the French working population. The study was based on a national random sample of 3765 men and 3944 women of the French working population (SIP 2006 survey). Major Depressive Disorder (MDD) and Generalised Anxiety Disorder (GAD) were measured using a standardised diagnostic interview (MINI). Occupational factors included psychosocial work factors as well as biomechanical, physical, and chemical exposures. Adjustment variables included age, occupation, marital status, social support, and life events. Multivariate analysis was performed using logistic regression analysis. Low decision latitude, overcommitment, and emotional demands were found to be risk factors for both MDD-GAD among both genders. Other risk factors were observed: high psychological demands, low reward, ethical conflict, and job insecurity, but differences were found according to gender and outcome. Significant interaction terms were observed suggesting that low decision latitude, high psychological demands, and job insecurity had stronger effects on mental disorders for men than for women. Given the cross-sectional study design, no causal conclusion could be drawn. This study showed significant associations between classical and emergent psychosocial work factors and MDD-GAD. Preventive actions targeting various psychosocial work factors, including emergent factors, may help to reduce mental disorders at the workplace. Copyright © 2012 Elsevier B.V. All rights reserved.

The work motivations of mothers with preschool children.

1989-06-01

This article provides a qualitative and quantitative analysis of the motivations for employment among a sample of 166 Sydney mothers, each of whom had at least 1 preschool-aged child. Mothers with high and moderate work attachment indicated a multiplicity of motives, of both an extrinsic (financial) and intrinsic (personal satisfaction, sense of achievement) nature. In contrast, the majority of women with low work attachment cited extreme financial need as the only possible reason that would impel them to enter the labor force. When asked which was, or would be, their most important reason for working, women with high work attachment endorsed more nonfinancial than financial reasons, women with moderate work attachment were about equally likely to give either reason, and women with low work attachment predominantly gave financial reasons. Husbands' perceptions of the reasons their wives were working, or would work, showed some, but not complete, agreement with those of their wives.

a Study of Women Engineering Students and Time to Completion of First-Year Required Courses at Texas A&M University

This paper reports findings on gender that were part of a larger study reviewing time to completion of course work that includes the first two semesters of calculus, chemistry, and physics, which are often considered the stumbling points or "barrier courses" to an engineering baccalaureate degree. Texas A&M University terms these courses core body of knowledge (CBK), and statistical analysis was conducted on two cohorts of first-year enrolling engineering students at the institution. Findings indicate that gender is statistically significantly related to completion of CBK with female engineering students completing required courses faster than males at the .01 level (p = 0.008). Statistical significance for gender and ethnicity was found between white male and white female students at the .01 level (p = 0.008). Descriptive analysis indicated that of the five majors studied (chemical, civil, computer, electrical, and mechanical engineering), women completed CBK faster than men, and African American and Hispanic women completed CBK faster than males of the same ethnicity.

Teaching statistics in biology: using inquiry-based learning to strengthen understanding of statistical analysis in biology laboratory courses.

PubMed

Metz, Anneke M

2008-01-01

There is an increasing need for students in the biological sciences to build a strong foundation in quantitative approaches to data analyses. Although most science, engineering, and math field majors are required to take at least one statistics course, statistical analysis is poorly integrated into undergraduate biology course work, particularly at the lower-division level. Elements of statistics were incorporated into an introductory biology course, including a review of statistics concepts and opportunity for students to perform statistical analysis in a biological context. Learning gains were measured with an 11-item statistics learning survey instrument developed for the course. Students showed a statistically significant 25% (p < 0.005) increase in statistics knowledge after completing introductory biology. Students improved their scores on the survey after completing introductory biology, even if they had previously completed an introductory statistics course (9%, improvement p < 0.005). Students retested 1 yr after completing introductory biology showed no loss of their statistics knowledge as measured by this instrument, suggesting that the use of statistics in biology course work may aid long-term retention of statistics knowledge. No statistically significant differences in learning were detected between male and female students in the study.

Education research and scholarship are essential for promotion of faculty as well as dissemination of new educational practices. Educational faculty frequently spend the majority of their time on administrative and educational commitments and as a result educators often fall behind on scholarship and research. The objective of this educational advance is to promote scholarly productivity as a template for others to follow. We formed the Medical Education Research Group (MERG) of education leaders from our emergency medicine residency, fellowship, and clerkship programs, as well as residents with a focus on education. First, we incorporated scholarship into the required activities of our education missions by evaluating the impact of programmatic changes and then submitting the curricula or process as peer-reviewed work. Second, we worked as a team, sharing projects that led to improved motivation, accountability, and work completion. Third, our monthly meetings served as brainstorming sessions for new projects, research skill building, and tracking work completion. Lastly, we incorporated a work-study graduate student to assist with basic but time-consuming tasks of completing manuscripts. The MERG group has been highly productive, achieving the following scholarship over a three-year period: 102 abstract presentations, 46 journal article publications, 13 MedEd Portal publications, 35 national didactic presentations and five faculty promotions to the next academic level. An intentional focus on scholarship has led to a collaborative group of educators successfully improving their scholarship through team productivity, which ultimately leads to faculty promotions and dissemination of innovations in education.

To ascertain the views of senior house officers and registrars on the educational and training component of their posts, a questionnaire was sent to all full-time doctors working in training posts in general and/or geriatric medicine at three district general and three teaching hospitals. Completed questionnaires were received from 64 (61%) of 105 doctors who were contacted. Most had a careers counsellor or tutor, although less than two-thirds thought they had benefited from this arrangement. The majority of doctors attended at least two medical tutorials or meetings per week; most wanted to attend more but were unable to because of other work commitments. Supervision by more senior staff on the ward was deemed by most to be satisfactory, but less so in out-patient clinics. Overall, one-third of doctors thought that training was inadequate and three-quarters wanted a greater amount of formal education. The majority of junior doctors' time was spent on routine work and most considered :training' constituted less than 10% of their working time. Doctors in training require more sessions designated as educational, with protected time to attend these. PMID:8949591

Small-Group Learning in an Upper-Level University Biology Class Enhances Academic Performance and Student Attitudes Toward Group Work

2010-01-01

To improve science learning, science educators' teaching tools need to address two major criteria: teaching practice should mirror our current understanding of the learning process; and science teaching should reflect scientific practice. We designed a small-group learning (SGL) model for a fourth year university neurobiology course using these criteria and studied student achievement and attitude in five course sections encompassing the transition from individual work-based to SGL course design. All students completed daily quizzes/assignments involving analysis of scientific data and the development of scientific models. Students in individual work-based (Individualistic) sections usually worked independently on these assignments, whereas SGL students completed assignments in permanent groups of six. SGL students had significantly higher final exam grades than Individualistic students. The transition to the SGL model was marked by a notable increase in 10th percentile exam grade (Individualistic: 47.5%; Initial SGL: 60%; Refined SGL: 65%), suggesting SGL enhanced achievement among the least prepared students. We also studied student achievement on paired quizzes: quizzes were first completed individually and submitted, and then completed as a group and submitted.

To improve science learning, science educators' teaching tools need to address two major criteria: teaching practice should mirror our current understanding of the learning process; and science teaching should reflect scientific practice. We designed a small-group learning (SGL) model for a fourth year university neurobiology course using these criteria and studied student achievement and attitude in five course sections encompassing the transition from individual work-based to SGL course design. All students completed daily quizzes/assignments involving analysis of scientific data and the development of scientific models. Students in individual work-based (Individualistic) sections usually worked independently on these assignments, whereas SGL students completed assignments in permanent groups of six. SGL students had significantly higher final exam grades than Individualistic students. The transition to the SGL model was marked by a notable increase in 10th percentile exam grade (Individualistic: 47.5%; Initial SGL: 60%; Refined SGL: 65%), suggesting SGL enhanced achievement among the least prepared students. We also studied student achievement on paired quizzes: quizzes were first completed individually and submitted, and then completed as a group and submitted. The group quiz grade was higher than the individual quiz grade of the highest achiever in each group over the term. All students--even term high achievers--could benefit from the SGL environment. Additionally, entrance and exit surveys demonstrated student attitudes toward SGL were more positive at the end of the Refined SGL course. We assert that SGL is uniquely-positioned to promote effective learning in the science classroom.

New insights from IODP Expedition 340 offshore Montserrat: First drilling of large volcanic island landslides

Montserrat now provides one of the most complete datasets for understanding the character and tempo of hazardous events at volcanic islands. Much of the erupted material ends up offshore, and this offshore record may be easier to date due to intervening hemiplegic sediments between event beds. The offshore dataset includes the first scientific drilling of volcanic island landslides during IODP Expedition 340, together with an unusually comprehensive set of shallow sediment cores and 2-D and 3-D seismic surveys. Most recently in 2013, Remotely Operated Vehicle (ROV) dives mapped and sampled the surface of the main landslide deposits. This contribution aims to provide an overview of key insights from ongoing work on IODP Expedition 340 Sites offshore Montserrat.Key objectives are to understand the composition (and hence source), emplacement mechanism (and hence tsunami generation) of major landslides, together with their frequency and timing relative to volcanic eruption cycles. The most recent major collapse event is Deposit 1, which involved ~1.8 km cubed of material and produced a blocky deposit at ~12-14ka. Deposit 1 appears to have involved not only the volcanic edifice, but also a substantial component of a fringing bioclastic shelf, and material locally incorporated from the underlying seafloor. This information allows us to test how first-order landslide morphology (e.g. blocky or elongate lobes) is related to first-order landslide composition. Preliminary analysis suggests that Deposit 1 occurred shortly before a second major landslide on the SW of the island (Deposit 5). It may have initiated English's Crater, but was not associated with a major change in magma composition. An associated turbidite-stack suggests it was emplaced in multiple stages, separated by at least a few hours and thus reducing the tsunami magnitude. The ROV dives show that mega-blocks in detail comprise smaller-scale breccias, which can travel significant distances without complete disintegration. Landslide Deposit 2 was emplaced at ~130ka, and is more voluminous (~8.4km cubed). It had a much more profound influence on the magmatic system, as it was linked to a major explosive mafic eruption and formation of a new volcanic centre (South Soufriere Hills) on the island. Site U1395 confirms a hypothesis based on the site survey seismic data that Deposit 2 includes a substantial component of pre-existing seafloor sediment. However, surprisingly, this pre-existing seafloor sediment in the lower part of Deposit 2 at Site U1395 is completely undeformed and flat lying, suggesting that Site U1395 penetrated a flat lying block. Work to date material from the upper part of U1396, U1395 and U1394 will also be summarised. This work is establishing a chronostratigraphy of major events over the last 1 Ma, with particularly detailed constraints during the last ~250ka. This is helping us to understand whether major landslides are related to cycles of volcanic eruptions.

To estimate the prevalence of carriage of methicillin-resistant Staphylococcus aureus (MRSA) among Australian veterinarians. Individuals attending veterinary conferences in Australia in 2009 were recruited to provide nasal swabs and complete a questionnaire about their professional activities. Swabs were processed by standard methods for detecting MRSA and questionnaire responses were used to group veterinarians according to their areas of major work emphasis (species and practice type). Prevalence was estimated for each of these grouping and contingency tables and regression tree analysis used to explain the variation in MRSA carriage. Among the 771 respondents 'industry and government veterinarians' (controls) had the lowest prevalence of MRSA carriage at 0.9%. Veterinarians with horses as a major area of work emphasis had a prevalence of 11.8% (13-fold that of controls) and those whose only major emphasis was horses had a prevalence of 21.4% (23-fold that of controls). Veterinarians with dogs and cats as a major activity had a 4.9% prevalence (5-fold that of controls). Prevalence rates for other major activities (pigs, dairy and beef cattle, avian and wildlife) were also increased, but were estimated from smaller numbers of respondents. Regression tree analysis clearly isolated equine veterinarians and dog and cat practitioners as groups at increased risk of carriage of MRSA. Carriage of MRSA is a notable occupational health issue for veterinarians in clinical practice in Australia, particularly those who work with horses. © 2011 The Authors.

From Ancient times, medicinal broths have been an integral part of the diet fed to patients and convalescents. At the end of 17th century, medical and pharmaceutical knowledge and practices were to enter a period of major upheavals. Although also hitherto discredited, chemical drugs became all the rage, work in chemistry boomed and broths benefited. Do the first editions of the works of Nicolas Lemery reflect the knowledge of his time ? Do last editions – revised, corrected, annotated and completed – really reflect transformations in scientific disciplines, technological developments, and scientific advances, particularly in chemistry?

Demographic trends in developed countries have prompted governmental policies aimed at extending working lives. However, working beyond the traditional retirement age may not be feasible for those with major health problems of ageing, and depending on occupational and personal circumstances, might be either good or bad for health. To address these uncertainties, we have initiated a new longitudinal study. We recruited some 8000 adults aged 50-64 years from 24 British general practices contributing to the Clinical Practice Research Datalink (CPRD). Participants have completed questionnaires about their work and home circumstances at baseline, and will do so regularly over follow-up, initially for a 5-year period. With their permission, we will access their primary care health records via the CPRD. The inter-relation of changes in employment (with reasons) and changes in health (e.g., major new illnesses, new treatments, mortality) will be examined. CPRD linkage allows cost-effective frequent capture of detailed objective health data with which to examine the impact of health on work at older ages and of work on health. Findings will inform government policy and also the design of work for older people and the measures needed to support employment in later life, especially for those with health limitations.

to explore the nature of leadership styles used by the nursing management team, as perceived by nurses working at the bedside. leadership style is related to job satisfaction, staff retention, costs, and quality of care. The leadership styles of managers can be crucial in the healthcare setting, but very few studies have focused on them. the study employed qualitative methodology, involving 35 nurses working in different specialties of a medical city in Saudi Arabia. Data collection consisted of completing demographic and professional information and a semi-structured interview using open-ended questions. a phenomenologic-hermeneutic approach was used to identify major themes. the findings showed that participants described four types of leadership styles: relational leadership, preferential leadership, communication chain leadership, and ineffectual leadership. the leadership style employed by nurse managers has a major impact on nurses' satisfaction, turnover, and the quality of patient care they deliver.

The severity of symptoms, rate and completeness of recovery after closed treatment of the fractured clavicle has not been fully explored. The severity and duration of pain, analgesic requirements, ability to perform daily activities, return to work, driving and sport along with appearance of the shoulder were recorded in 56 patients between 1 and 2 years after fracture. Radiographs were assessed by Robinson's classification [8]. Twenty-two out of 56 patients described functional restriction 1-2 years after injury. The majority of patients ceased to experience pain (34/56) and returned to work (19/46) within 3 months. Thirty-eight out of 56 patients noted cosmetic deformity, the severity of which was associated with worse functional outcome (p = 0.002). The degree of fracture displacement was associated with cosmetic deformity (p = 0.02) and functional outcome (p = 0.015). The majority of patients perceive a cosmetic deformity and 22/56 impaired function after clavicular fracture.

Fitting in and feeling good: the relationships among peer alignment, instructor connectedness, and self-efficacy in undergraduate satisfaction with engineering

This study examined the relationships among peer alignment (the feeling that one is similar in important ways to one's engineering peers), instructor connectedness (the sense that one knows and looks up to academic staff/faculty members in the department), self-efficacy for engineering class work (confidence in one's ability to successfully complete engineering class work), and engineering students' satisfaction with the major. A total of 135 sophomore (second-year university students) and junior (third-year students) engineering students were surveyed to measure these three variables. A multiple regression analysis showed that self-efficacy, peer alignment, and instructor connectedness predicted student satisfaction with the major, and that self-efficacy acted as a mediator between both peer alignment and instructor connectedness on the one hand, and satisfaction on the other. The authors offer suggestions for practice based on the results.

In April 1988, the US and the former-USSR signed a Memorandum of Cooperation (MOC) for Civilian Nuclear Reactor Safety; this MOC was a direct result of the accident at the Chernobyl Nuclear Power Plant Unit 4 and the following efforts by the two countries to implement a joint program to improve the safety of nuclear power plants and to understand the implications of environmental releases. A Joint Coordinating Committee for Civilian Nuclear Reactor Safety (JCCCNRS) was formed to implement the MOC. The JCCCNRS established many working groups; most of these were the responsibility of the Nuclear Regulatory Commission, as farmore » as the US participation was concerned. The lone exception was Working Group 7 on Environmental Transport and Health Effects, for which the US participation was the responsibility of the US Department of Energy (DOE). The purpose of Working Group 7 was succintly stated to be, ``To develop jointly methods to project rapidly the health effects of any future nuclear reactor accident.`` To implement the work DOE then formed two subworking groups: 7.1 to address Environmental Transport and 7.2 to address Health Effects. Thus, the DOE-funded Chernobyl Studies Project began. The majority of the initial tasks for this project are completed or near completion. The focus is now turned to the issue of health effects from the Chernobyl accident. Currently, we are involved in and making progress on the case-control and co-hort studies of thyroid diseases among Belarussian children. Dosimetric aspects are a fundamental part of these studies. We are currently working to implement similar studies in Ukraine. A major part of the effort of these projects is supporting these studies, both by providing methods and applications of dose reconstruction and by providing support and equipment for the medical teams.« less

Reducing perceived stigma: Work integration of people with severe mental disorders in Italian social enterprise.

People with mental illnesses face stigma that hinders their full integration into society. Work is a major determinant of social inclusion, however, people with mental disorders have fewer opportunities to work. Emerging evidence suggests that social enterprises help disadvantaged people with their work integration process. The purpose of this study is to enhance our understanding about how perceptions of stigma can be decreased for people with mental disorders throughout their work experience in a social enterprise. Using a longitudinal study design, 310 individuals with mental disorders employed in Italian social enterprises completed a battery of questionnaires on individual (e.g., severity of symptoms; occupational self-efficacy) and environmental (e.g., social support; organizational constraints) variables. Of the 223 individuals potentially eligible at the 12-month follow up, 139 completed a battery of questionnaires on social and working skills, perceived work productivity and perceived stigma. Path analyses were used to test a model delineating how people with mental disorders working in social enterprises improve social and work outcomes (i.e., motivation, skills and productivity), and reduce the perception of being stigmatized. Working in a social enterprise enhances working social skills, which leads to a perception of higher productivity and, consequently, the perception of being discriminated against and stigmatized is reduced. Social enterprise provides a context in which people with mental disorders reach a sense of work-related and social competence. This sense of competence helps them to reduce perceived stigma, which is a crucial step toward social inclusion. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Objective To estimate the prevalence of unemployment and part-time employment in the United States for working-age individuals completing rehabilitation for a primary diagnosis of traumatic brain injury (TBI) between 2001 and 2010. Design Secondary data analysis. Setting Acute inpatient rehabilitation facilities. Participants Patients aged 16 to 60 years at injury who completed inpatient rehabilitation for TBI between 2001 and 2010. Main Outcome Measures Unemployment; Part-time employment. Results The prevalence of unemployment for persons in the selected cohort was 60.4% at 2-year postinjury. Prevalence of unemployment at 2-year postinjury was significantly associated with the majority of categories of age group, race, gender, marital status, primary inpatient rehabilitation payment source, education, preinjury vocational status, length of stay, and Disability Rating Scale. The direction of association for the majority of these variables complement previous research in this area, with only Hispanic ethnicity and the FIM Cognitive subscale demonstrating disparate findings. For those employed at 2-year postinjury, the prevalence of part-time employment was 35.0%. The model of prevalence for part-time employment at 2-year postinjury was less robust, with significant relationships with some categorical components of age group, gender, marital status, primary payment source, preinjury vocational status, and Disability Rating Scale. Conclusions The prevalence of unemployment for patients completing inpatient rehabilitation for TBI was substantial (60.4%). The majority of factors found to associate with 2 years’ unemployment were complementary of previously published research; however, these were often smaller in magnitude than previous reports. The prevalence of part-time employment was also an issue for this cohort and included 35.0% of all employed individuals. In regard to the determination of factors associated with part-time employment, additional analyses that include more fine-grained factors associated with employment, including physical and psychosocial functioning, are recommended.

Socio-demographic characteristics of mothers have been associated with exclusive breastfeeding duration, but little is known about the association with maternal full- and part-time employment and return to work in European countries. To study the associations between breastfeeding, any and almost exclusive (infants receiving breast milk as their only milk) breastfeeding, at 4 months of infant's age and the socio-demographic and occupational characteristics of mothers. We used the EDEN mother-child cohort, a prospective study of 2002 singleton pregnant women in two French university hospitals. We selected all mothers (n = 1,339) who were breastfeeding at discharge from the maternity unit. Data on feeding practices were collected at the maternity unit and by postal questionnaires at 4, 8 and 12 months after the birth. Among infants breastfed at discharge, 93% were still receiving any breastfeeding (83% almost exclusive breastfeeding) at the 3rd completed week of life, 78% (63%) at the 1st completed month, and 42% (20%) at the 4th completed month. Time of return to work was a major predictor for stopping breastfeeding: the sooner the mothers returned to work, the less they breastfed their babies at 4 months of infant's age, independently of full-time or part-time employment. The association was stronger for almost exclusive breastfeeding mothers than for any breastfeeding ones. In a society where breastfeeding is not the norm, women may have difficulties combining work and breastfeeding. Specific actions need to be developed and assessed among mothers who return to work and among employers.

The EM SSAB Annual Work Plan Process: Focusing Board Efforts and Resources - 13667

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

Young, Ralph

One of the most daunting tasks for any new member of a local board of the Environmental Management Site Specific Advisory Board (EM SSAB) is to try to understand the scope of the clean-up activities going on at the site. In most cases, there are at least two or three major cleanup activities in progress as well as monitoring of past projects. When planning for future projects is added to the mix, the list of projects can be long. With the clean-up activities involving all major environmental media - air, water, soils, and groundwater, new EM SSAB members can findmore » themselves totally overwhelmed and ineffective. Helping new members get over this initial hurdle is a major objective of EM and all local boards of the EM SSAB. Even as members start to understand the size and scope of the projects at a site, they can still be frustrated at the length of time it takes to see results and get projects completed. Many project and clean-up timelines for most of the sites go beyond 10 years, so it's not unusual for an EM SSAB member to see the completion of only 1 or 2 projects over the course of their 6-year term on the board. This paper explores the annual work planning process of the EM SSAB local boards, one tool that can be used to educate EM SSAB members into seeing the broader picture for the site. EM SSAB local work plans divide the site into projects focused on a specific environmental issue or media such as groundwater and/or waste disposal options. Projects are further broken down into smaller segments by highlighting major milestones. Using these metrics, local boards of the EM SSAB can start to quantify the effectiveness of the project in achieving the ultimate goal of site clean-up. These metrics can also trigger board advice and recommendations for EM. At the beginning of each fiscal year, the EM SSAB work plan provides a road map with quantifiable checkpoints for activities throughout the year. When the work plans are integrated with site-specific, enforceable regulatory milestones, they can provide a comprehensive work plan for not only the board, but also regulators, site contractors, and DOE. Because the work plans are reviewed and approved by DOE, they carry some weight in holding local boards of the EM SSAB accountable. This structure provides the basis for local boards to achieve their primary function, to provide DOE with information, advice, and recommendations concerning issues affecting the EM program at the site.

A healthy work environment can improve patient outcomes and registered nurse (RN) turnover. Creating cultures of retention and fostering healthy work environments are 2 major challenges facing nurse leaders today. Examine the effects of the healthy work environment (communication, collaboration, and leadership) on RN turnover from data collected from a research study. Descriptive, cross-sectional, correlational design. Pediatric critical care RNs from 10 pediatric intensive care units (PICU) completed the Practice Environment Scale of the Nursing Work Index Revised and a subscale of the Intensive Care Unit Nurse-Physician Communication Questionnaire. These staff nurses were asked whether they intend to leave their current job in the next 6 months. Statistical analysis included correlations, multiple linear regression, t tests (2-tailed), and 1-way analysis of variance. A total of 415 RNs completed the survey. There was a statistically significant relationship between leadership and the intent to leave (P < .05). There was also an inverse relationship between years of experience and intent to leave. None of the communication variables between RNs and among RNs and MDs or collaboration were significantly associated with PICU nurses' intention to leave. Effective leadership in the PICU is important to PICU RNs and significantly influences their decisions about staying in their current job.

Global Failure Modes in Composite Structures for High Altitudes

This report summarizes the accomplishments under the referenced grant. The work described was started under the guidance and supervision of the late Dr. James Stames as the technical contact. It was aimed at investigating the development of analysis tools to deal with the problem of rupture in reinforced structural skin of future composites-based aircraft. It was of particular interest to assess methods by which failure features reminiscent of cracks in metallic structures would develop and propagate in fiber reinforced structures in interaction with the reinforcing frame. To eventually achieve that goal it was necessary to first understand the stress or strain distribution at the front of such features so that interactions between such features and reinforcing agents could be assessed computationally. Thus the major emphasis here was on the assessment of damage front and methods on how to assess or characterize it. During the conduct of this research program Dr. Stames changed to a different NASA- internal assignment, which divorced him of the direct supervision of this grant. A student who was approximately % into the completion of his Ph.D. research needed to finish this work, and NASA funds were made available under Dr. Damodar Ambur, the successor Branch Manager for Dr. James Starnes, for the completion of this work. The current grant was the thus a new and fmal support increment for completion of the started research. Final reports for previous funding have been completed and submitted. Because of the interconnection of this last phase of the investigation with previous work it is deemed useful to make the Ph.D. thesis by Luis Gonzales the body of this report.

Teaching Statistics in Biology: Using Inquiry-based Learning to Strengthen Understanding of Statistical Analysis in Biology Laboratory Courses

PubMed Central

2008-01-01

There is an increasing need for students in the biological sciences to build a strong foundation in quantitative approaches to data analyses. Although most science, engineering, and math field majors are required to take at least one statistics course, statistical analysis is poorly integrated into undergraduate biology course work, particularly at the lower-division level. Elements of statistics were incorporated into an introductory biology course, including a review of statistics concepts and opportunity for students to perform statistical analysis in a biological context. Learning gains were measured with an 11-item statistics learning survey instrument developed for the course. Students showed a statistically significant 25% (p < 0.005) increase in statistics knowledge after completing introductory biology. Students improved their scores on the survey after completing introductory biology, even if they had previously completed an introductory statistics course (9%, improvement p < 0.005). Students retested 1 yr after completing introductory biology showed no loss of their statistics knowledge as measured by this instrument, suggesting that the use of statistics in biology course work may aid long-term retention of statistics knowledge. No statistically significant differences in learning were detected between male and female students in the study. PMID:18765754

The majority of medical graduates in Germany complete a doctorate, even though a doctoral degree is not necessary for the practice of medicine. So far, little is known about doctoral candidates' view on the individual benefit a doctoral thesis has for them. Consequently, this is the subject of the present investigation. Data from surveys with graduates of the five medical faculties of Baden-Württemberg from the graduation years 2007/2008 (N=514) and 2010/2011 (N=598) were analysed. One and a half years after graduating 53% of those interviewed had completed their doctorate. When asked about their motivation for writing a doctoral thesis, participants answered most frequently "a doctorate is usual" (85%) and "improvement of job opportunities" (75%), 36% said that an academic career has been their primary motive. Less than 10% responded that they used their doctoral thesis as a means to apply for a job. The proportion of graduates working in health care is equally large among those who have completed a thesis and those who have not. Graduates who pursued a thesis due to scientific interest are also currently more interested in an academic career and recognise more opportunities for research. An implicit benefit of a medical thesis emerged with regard to the self-assessment of scientific competences as those who completed a doctorate rated their scientific competencies higher than those who have not. Although for the majority of physicians research interest is not the primary motivation for completing a doctorate, they might nevertheless achieve some academic competencies. For graduates pursuing an academic career the benefit of completing a medical thesis is more obvious.

This study reports the findings of 120 traumatic pad injuries in pet and military dogs. Most dogs (68%) presented with a laceration to a thoracic limb footpad, and one-third of dogs were middle-aged castrated males. Metacarpal pads were most commonly injured. Short-term complications were noted in 27% of dogs. No long-term complications were identified. No disability from pad injury was present at the completion of healing. Concurrent injuries to adjacent structures were uncommon and did not affect outcome. Dogs with full-thickness pad lacerations were at greater risk for major short-term complications compared to dogs with partial-thickness pad lacerations (odds ratio, 7.27; P = .001). Military working dogs with full-thickness pad lacerations were at greater risk for major short-term complications than pet dogs with a similar injury. When major complications developed in dogs with full-thickness pad injuries, time to final healing was significantly longer (by a median of 12 days). The partial-thickness pad lesions healed uneventfully regardless of whether they were bandaged, surgically repaired, or left to heal by second intention. Suture repair and bandaging of full-thickness lesions could not be shown to either decrease the risk for complications or improve healing. Future work should focus on establishing standards for footpad treatment to reduce complications.

Military activities in hot environments pose 2 competing demands: the requirement to perform realistic training to develop operational capability with the necessity to protect armed forces personnel against heat-related illness. To ascertain whether work duration limits for protection against heat-related illness restrict military activities, this study examined the heat strain and risks of heat-related illness when conducting a military activity above the prescribed work duration limits. Thirty-seven soldiers conducted a march (10 km; ∼5.5 km h -1 ) carrying 41.8 ± 3.6 kg of equipment in 23.1 ± 1.8°C wet-bulb globe temperature. Body core temperature was recorded throughout and upon completion, or withdrawal, participants rated their severity of heat-related symptoms. Twenty-three soldiers completed the march in 107 ± 6.4 min (Completers); 9 were symptomatic for heat exhaustion, withdrawing after 71.6 ± 10.1 min (Symptomatic); and five were removed for body core temperature above 39.0°C (Hyperthermic) after 58.4 ± 4.5 min. Body core temperature was significantly higher in the Hyperthermic (39.03 ± 0.26°C), than Symptomatic (38.34 ± 0.44°C; P = 0.007 ) and Completers (37.94 ± 0.37°C; P<0.001 ) after 50 min. Heat-related symptom severity was significantly higher among Symptomatic (28.4 ± 11.8) compared to Completers (15.0 ± 9.8, P = 0.006 ) and Hyperthermic (13.0 ± 9.6, P = 0.029 ). The force protection provided by work duration limits may be preventing the majority of personnel from conducting activities in hot environments, thereby constraining a commander's mandate to develop an optimised military force. The dissociation between heat-related symptoms and body core temperature elevation suggests that the physiological mechanisms underpinning exhaustion during exertional heat stress should be re-examined to determine the most appropriate physiological criteria for prescribing work duration limits.

How social networks influence female students' choices to major in engineering

NASA Astrophysics Data System (ADS)

Weinland, Kathryn Ann

Scope and Method of Study: This study examined how social influence plays a part in female students' choices of college major, specifically engineering instead of science, technology, and math. Social influence may show itself through peers, family members, and teachers and may encompass resources under the umbrella of social capital. The purpose of this study was to examine how female students' social networks, through the lens of social capital, influence her major choice of whether or not to study engineering. The variables of peer influence, parental influence, teacher/counselor influence, perception of engineering, and academic background were addressed in a 52 question, Likert scale survey. This survey has been modified from an instrument previously used by Reyer (2007) at Bradley University. Data collection was completed using the Dillman (2009) tailored design model. Responses were grouped into four main scales of the dependent variables of social influence, encouragement, perceptions of engineering and career motivation. A factor analysis was completed on the four factors as a whole, and individual questions were not be analyzed. Findings and Conclusions: This study addressed the differences in social network support for female freshmen majoring in engineering versus female freshmen majoring in science, technology, or math. Social network support, when working together from all angles of peers, teachers, parents, and teachers/counselors, transforms itself into a new force that is more powerful than the summation of the individual parts. Math and science preparation also contributed to female freshmen choosing to major in engineering instead of choosing to major in science, technology, or math. The STEM pipeline is still weak and ways in which to reinforce it should be examined. Social network support is crucial for female freshmen who are majoring in science, technology, engineering, and math.

Appavoo, Jonathan

Exascale computing systems will provide a thousand-fold increase in parallelism and a proportional increase in failure rate relative to today's machines. Systems software for exascale machines must provide the infrastructure to support existing applications while simultaneously enabling efficient execution of new programming models that naturally express dynamic, adaptive, irregular computation; coupled simulations; and massive data analysis in a highly unreliable hardware environment with billions of threads of execution. The FOX project explored systems software and runtime support for a new approach to the data and work distribution for fault oblivious application execution. Our major OS work at Boston University focusedmore » on developing a new light-weight operating systems model that provides an appropriate context for both multi-core and multi-node application development. This work is discussed in section 1. Early on in the FOX project BU developed infrastructure for prototyping dynamic HPC environments in which the sets of nodes that an application is run on can be dynamically grown or shrunk. This work was an extension of the Kittyhawk project and is discussed in section 2. Section 3 documents the publications and software repositories that we have produced. To put our work in context of the complete FOX project contribution we include in section 4 an extended version of a paper that documents the complete work of the FOX team.« less

International students studying nursing in the United States present unique teaching opportunities and challenges. Student language, culture, and academic expectations are major factors for faculty to consider in delivering international education. An RN to BSN program provides baccalaureate completion study for registered nurses residing in Israel. Students can choose to complete the final semester in the United States. Israeli nursing students demonstrate a strong collectivistic orientation to their academic work. Issues related to English language fluency and academic paper preparation were identified. Success in international teaching endeavors is facilitated when faculty carefully evaluate course materials and assignments. Clarity of language, cultural expectations, and availability of academic resources are important considerations for promoting student success.

The aims of this study were to assess the prevalence of unresolved grief in bereaved young adult siblings and examine possible contributing factors. The study was a Swedish population-based study of young adults who had lost a brother or sister to cancer, 2-9 years earlier. Of 240 eligible siblings, 174 (73%) completed a study-specific questionnaire. This study focused on whether the respondents had worked through their grief over the sibling's death and to what extent. A majority (54%) of siblings stated that they had worked through their grief either 'not at all' or 'to some extent' at the time of investigation. In multiple regression analyses with unresolved grief as the dependent variable, 21% of the variance was explained by lack of social support and shorter time since loss. The majority of bereaved young adults had not worked through their grief over the sibling's death. A small group of siblings reported that they had not worked through their grief at all, which may be an indicator of prolonged grief. Lack of social support and more recent loss were associated with not having worked through the grief over the sibling's death. Copyright © 2013 John Wiley & Sons, Ltd.

Use of control umbilicals as a deployment mode for free flying telerobotic work systems

NASA Technical Reports Server (NTRS)

Kuehn, J. S.; Selle, E. D.

1987-01-01

Work to date on telerobotic work systems for use in space generally consider two deployment modes, free flying, or fixed within a limited work envelope. Control tethers may be employed to obtain a number of operational advantages and added flexibility in the basing and deployment of telerobotic work systems. Use of a tether allows the work system to be separated into two major modules, the remote work package and the control module. The Remote Work Package (RWP) comprises the free flying portion of the work system while the Control Module (CM) remains at the work system base. The chief advantage of this configuration is that only the components required for completion of the work task must be located at the work site. Reaction mass used in free flight is stored at the Control module and supplied to the RWP through the tether, eliminating the need for the RWP to carry it. The RWP can be made less massive than a self contained free flying work system. As a result, reaction mass required for free flight is lower than for a self contained free flyer.

Importance of participation in major life areas matters for return to work.

The complexity of the process and outcome of vocational rehabilitation yearns for a multifaceted approach. This article investigates whether importance of participation in major life areas for men and women predicts the outcome of vocational rehabilitation. This longitudinal study provides measure points at the start of the intervention (T1), at the end of the intervention (T2) and at a follow-up 6-12 months after completing the rehabilitation program (T3). Associations were assessed by nominal logistic regression. The importance of participation in work was positively associated to return to work (RTW), while the importance of participation in leisure activities and importance of participation in family was negatively associated with RTW after the rehabilitation. Gender and number of children also contributed significantly to the regression model. To identify individuals' subjective evaluation of the importance of participation may be of value in explaining return or not RTW and contribute to explain gender differences in outcomes. It may also inform rehabilitation counselors in collaboration with clients and facilitate tailoring interventions to the individual's needs.

Optimal proximity correction: application for flash memory design

Proximity Correction is the technology for which the most of IC manufacturers are committed already. The final intended result of correction is affected by many factors other than the optical characteristics of the mask-stepper system, such as photoresist exposure, post-exposure bake and development parameters, etch selectivity and anisotropy, and underlying topography. The most advanced industry and research groups already reported immediate need to consider wafer topography as one of the major components during a Proximity Correction procedure. In the present work we are discussing the corners rounding effect (which eventually cause electrical leakage) observed for the elements of Poly2 layer for a Flash Memory Design. It was found that the rounding originated by three- dimensional effects due to variation of photoresist thickness resulting from the non-planar substrate. Our major goal was to understand the reasons and correct corner rounding. As a result of this work highly effective layout correction methodology was demonstrated and manufacturable Depth Of Focus was achieved. Another purpose of the work was to demonstrate complete integration flow for a Flash Memory Design based on photolithography; deposition/etch; ion implantation/oxidation/diffusion; and device simulators.

Lack of a clear perception of the realities of a career in veterinary medicine could adversely affect young graduates' satisfaction with the profession and their long-term commitment to it. Veterinary students' understanding of a career in practice were explored. Traditional-entry first-year and final-year students, as well as entry-level 'Gateway' (widening participation) students, were invited to complete a questionnaire exploring their pre-university experiences and their understandings of a career in general practice. Broadly speaking, the undergraduate students taking part in the survey (the majority of whom were entry-level students) had a realistic view of average weekly working hours, out-of-hours duties and the development of their remuneration packages over the course of their careers. The main attractions of the profession were working with animals and the perception of a rewarding job. The main concerns were making mistakes and balancing work and home life. The vast majority of students wanted to pursue a career in general practice, and other career opportunities did not appear to be well understood, particularly by entry-level students.

To examine the reliability of work-related activity coding for injury-related hospitalisations in Australia. A random sample of 4,373 injury-related hospital separations from 1 July 2002 to 30 June 2004 were obtained from a stratified random sample of 50 hospitals across four states in Australia. From this sample, cases were identified as work-related if they contained an ICD-10-AM work-related activity code (U73) allocated by either: (i) the original coder; (ii) an independent auditor, blinded to the original code; or (iii) a research assistant, blinded to both the original and auditor codes, who reviewed narrative text extracted from the medical record. The concordance of activity coding and number of cases identified as work-related using each method were compared. Of the 4,373 cases sampled, 318 cases were identified as being work-related using any of the three methods for identification. The original coder identified 217 and the auditor identified 266 work-related cases (68.2% and 83.6% of the total cases identified, respectively). Around 10% of cases were only identified through the text description review. The original coder and auditor agreed on the assignment of work-relatedness for 68.9% of cases. The best estimates of the frequency of hospital admissions for occupational injury underestimate the burden by around 32%. This is a substantial underestimate that has major implications for public policy, and highlights the need for further work on improving the quality and completeness of routine, administrative data sources for a more complete identification of work-related injuries.

A brief review is made of the major factors that are likely to cause eye discomfort from clerical work in traditional office environments. A procedure is proposed whereby cases of complaint may be systematically investigated. Methods are suggested for making a fairly quick evaluation of the task characteristics and the lighting conditions and it is suggested that measurements of the thermal characteristics of the environment also be carried out. In order to complete the investigation, it is necessary to obtain a person's subjective responses to the environment, using a suitably prepared questionairre, and for an eye examination to be performed by an ophthalmic optician.

Impact of Dry Eye Symptoms and Daily Activities in a Modern Office.

Modern offices and the use of electronic devices are increasing factors in work-related eye symptoms. However, symptoms of eye fatigue or dry eye sensation can be mixed and confusing. This study surveys the eye symptoms reported during a working day at modern offices to investigate the possible inhibition on daily work activities. Two online digital surveys were sent to three different work locations, by direct e-mail. Survey A consisted of 14 questions that investigated eye symptoms experienced during daily activities at work and the impact on daily activities. Survey B consisted of four general questions, the Dutch Ocular Surface Disease Index, the Work Productivity and Activity Index, and the Illness Perception Questionnaire. A total of 505 participants completed survey A, and 213 completed survey B. The participants reported that a high proportion of their day was spent working on a computer (60%). The majority experienced an air draft (79.1%) and had no adjustable light (81.5%) at their workspace. Dry eye-related symptoms were reported at a significantly higher frequency at work than at home (P < .001). Up to 70% experienced some inhibition of daily activity at work due to eye symptoms, with more than 5% experiencing symptoms most or all of the time. Indoor environment, work environment, and general health were perceived as the main reasons for developing dry eye. Compared with males, females showed a statistically significant higher Ocular Surface Disease Index score (P < .001) and experienced more inhibition and adverse effects on daily life and work productivity. This investigation shows that dry eye symptoms have a negative impact on daily activities at work. These findings suggest that multidisciplinary understanding of the negative impact of dry eye by a range of specialists will be of help in managing work-related dry eye.

NASA and its commercial industry team achieved significant progress in 2016 in manufacturing and testing of the Block 1 vehicle for the first launch of the Space Launch System (SLS). Test and flight article hardware for the liquid hydrogen fuel tank as well as the engine section for the core stage were completed at Michoud Assembly Facility (MAF) in New Orleans. Test stands neared completion at Marshall Space Flight Center for the propellant tanks, engine section, intertank and payload section. Stennis Space Center completed major structural renovations on the B2 test stand, where the core stage "green run" test program will be conducted. The SLS team completed a hotfire test series at Stennis to successfully demonstrate the ability of the RS-25 engine to operate under SLS environments and performance conditions. The team also test fired the second qualification five-segment solid rocket motor and cast the first six motor segments for the first SLS mission. The Interim Cryogenic Propulsion Stage (ICPS) test article was delivered to Marshall for structural tests, and work is nearly finished on the flight stage. Flight software testing completed at Marshall included power quality and command and data handling. In 2017, that work continues. SLS completed Preliminary Design Review (PDR) on the Exploration Upper Stage (EUS), a powerful, human-rated spacecraft that will propel explorers to cis-lunar space. In 2017, hardware will continue to be integrated at MAF for core stage structural test articles and the first two operational flights. RS-25 hotfire testing will continue to explore engine performance, as well as test flight-like software and four new Engine Controller Units (ECUs) for the first mission. Production of development components for a more affordable RS-25 design is underway. Core stage structural test articles have begun arriving at Marshall. While engineering challenges typical of a new development are possible, SLS is working toward launch readiness in late 2018. This paper will discuss these and other technical and programmatic successes and challenges over the past year and provide a preview of work ahead before first flight

Nurses constitute the majority of the health workforce in South Africa and they play a major role in providing primary health care (PHC) services. Job satisfaction influences nurse retention and successful implementation of health system reforms. This study was conducted in light of renewed government commitment to reforms at the PHC level, and to contribute to the development of solutions to the challenges faced by the South African nursing workforce. The objective of the study was to determine overall job satisfaction of PHC clinic nursing managers and the predictors of their job satisfaction in two South African provinces. During 2012, a cross-sectional study was conducted in two South African provinces. Stratified random sampling was used to survey a total of 111 nursing managers working in PHC clinics. These managers completed a pre-tested Measure of Job Satisfaction questionnaire with subscales on personal satisfaction, workload, professional support, training, pay, career prospects and standards of care. Mean scores were used to measure overall job satisfaction and various subscales. Predictors of job satisfaction were determined through multiple logistic regression analysis. A total of 108 nursing managers completed the survey representing a 97% response rate. The mean age of respondents was 49 years (SD = 7.9) and the majority of them (92%) were female. Seventy-six percent had a PHC clinical training qualification. Overall mean job satisfaction scores were 142.80 (SD = 24.3) and 143.41 (SD = 25.6) for Gauteng and Free State provinces respectively out of a maximum possible score of 215. Predictors of job satisfaction were: working in a clinic of choice (RRR = 3.10 (95% CI: 1.11 to 8.62, P = 0.030)), being tired at work (RRR = 0.19 (95% CI: 0.08 to 0.50, P = 0.001)) and experience of verbal abuse (RRR = 0.18 (95% CI: 0.06 to 0.55, P = 0.001). Allowing nurses greater choice of clinic to work in, the prevention of violence and addressing workloads could improve the practice environment and job satisfaction of PHC clinic nursing managers.

Greater poststroke disability and U.S. employment policies may disadvantage minority stroke survivors from returning to work. We explored ethnic differences in return to work among Mexican Americans (MAs) and non-Hispanic whites (NHWs) working at the time of their stroke. Stroke patients were identified from the population-based BASIC (Brain Attack Surveillance in Corpus Christi) study from August 2011 to December 2013. Employment status was obtained at baseline and 90-day interviews. Sequential logistic regression models were built to assess ethnic differences in return to work after accounting for the following: (1) age (<65 versus ≥65); (2) sex; (3) 90-day National Institutes of Health Stroke Scale (NIHSS); and (4) education (lower than high school versus high school or higher). Of the 729 MA and NHW stroke survivors who completed the baseline interview, 197 (27%) were working at the time of their stroke, of which 125 (63%) completed the 90-day outcome interview. Forty-nine (40%) stroke survivors returned to work by 90 days. MAs were less likely to return to work (OR = .45, 95% CI .22-.94) than NHWs. The ethnic difference became nonsignificant after adjusting for NIHSS (OR = .59, 95% CI .24-1.44) and further attenuated after adjusting for education (OR = .85, 95% CI .32- 2.22). The majority of stroke survivors did not return to work within 90 days of their stroke. MA stroke survivors were less likely to return to work after stroke than NHW stroke survivors which was due to their greater neurological deficits and lower educational attainment compared with that of NHW stroke survivors. Future work should focus on clinical and policy efforts to reduce ethnic disparities in return to work. Copyright © 2016 National Stroke Association. Published by Elsevier Inc. All rights reserved.

NASA's Space Launch System: Systems Engineering Approach for Affordability and Mission Success

Hutt, John J.; Whitehead, Josh; Hanson, John

2017-01-01

NASA is working toward the first launch of a new, unmatched capability for deep space exploration, with launch readiness planned for 2018. The initial Block 1 configuration of the Space Launch System will more than double the mass and volume to Low Earth Orbit (LEO) of any launch vehicle currently in operation - with a path to evolve to the greatest capability ever developed. The program formally began in 2011. The vehicle successfully passed Preliminary Design Review (PDR) in 2013, Key Decision Point C (KDPC) in 2014 and Critical Design Review (CDR) in October 2015 - nearly 40 years since the last CDR of a NASA human-rated rocket. Every major SLS element has completed components of test and flight hardware. Flight software has completed several development cycles. RS-25 hotfire testing at NASA Stennis Space Center (SSC) has successfully demonstrated the space shuttle-heritage engine can perform to SLS requirements and environments. The five-segment solid rocket booster design has successfully completed two full-size motor firing tests in Utah. Stage and component test facilities at Stennis and NASA Marshall Space Flight Center are nearing completion. Launch and test facilities, as well as transportation and other ground support equipment are largely complete at NASA's Kennedy, Stennis and Marshall field centers. Work is also underway on the more powerful Block 1 B variant with successful completion of the Exploration Upper Stage (EUS) PDR in January 2017. NASA's approach is to develop this heavy lift launch vehicle with limited resources by building on existing subsystem designs and existing hardware where available. The systems engineering and integration (SE&I) of existing and new designs introduces unique challenges and opportunities. The SLS approach was designed with three objectives in mind: 1) Design the vehicle around the capability of existing systems; 2) Reduce work hours for nonhardware/ software activities; 3) Increase the probability of mission success by focusing effort on more critical activities.

We describe learners enrolled in three iterations of introductory astronomy massive open online courses (MOOCs). These courses are offered through commercial providers and facilitated by an instructional team at the University of Arizona. We describe an ongoing study of those who enroll, engage in, and complete these courses. The course has undergone several revisions, including integrating pedagogical techniques, found to be effective for in-person courses, to increase engagement including peer review, online discussions, and the use of cohorts. In its current version, learners enroll on a continual basis and complete 11 weeks of course content; they watch videos, complete content quizzes, submit writing assignments, complete peer review of other students’ work, and complete online citizen science projects. Tens of thousands of students has signed up for these courses but completion rates are much lower, around 10%. We have collected survey data from over 8,500 of these learners to assess their basic science knowledge, attitudes towards science and technology, motivations for taking the courses, and information about other ways they engage in science related activities. We present information about these learners, including their demographics, motivations, how they use the courses, and what factors lead to increased engagement and completion. Additionally, we present how survey data from these learners compare to 26 years of data we have collected from parallel group of undergraduate non-science major students enrolled in astronomy courses at the University of Arizona. Overall, we find that learners who enroll in the MOOCs have more interest in science and higher basic science knowledge that undergraduates who pay tuition for a similar course. Our work is helping us understand how to better serve learners in MOOCs and bridge more traditional courses with these types of courses.

Participant attrition is a major concern for online continuing education health care courses. The current study sought to understand what factors predicted health care professionals completing the online component of a sexual assault forensic examiner (SAFE) blended learning training program (12-week online course and 2-day in-person clinical skills workshop). The study used a Web-based survey to examine participant characteristics, motivation, and external barriers that may influence training completion. Hierarchical logistic regression was utilized to examine the predictors of training completion, while the Cox proportional hazards (Cox PH) regression model helped determine the factors associated with the timing of participant attrition. Results show that 79.3% of the enrolled professionals completed the online component. The study also found that clinicians who work in rural communities and those who were interested in a 2-day clinical skills workshop were more likely to complete the online course. In terms of when attrition occurred, we found that participants who were motivated by the 2-day clinical workshop, those who worked in a rural community, and participants interested in the training program because of its online nature were more likely to complete more of the online course. Blending an online course with a brief in-person clinical component may serve as a motivator for completing an online course because it provides the opportunity to develop clinical skills while receiving immediate feedback. Participant attrition appears to be less of a concern for rural clinicians because this modality can reduce their barriers to accessing continuing education. © 2015 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on Continuing Medical Education, Association for Hospital Medical Education.

Giesler, Marianne; Boeker, Martin; Fabry, Götz; Biller, Silke

2016-01-01

Introduction: The majority of medical graduates in Germany complete a doctorate, even though a doctoral degree is not necessary for the practice of medicine. So far, little is known about doctoral candidates’ view on the individual benefit a doctoral thesis has for them. Consequently, this is the subject of the present investigation. Method: Data from surveys with graduates of the five medical faculties of Baden-Württemberg from the graduation years 2007/2008 (N=514) and 2010/2011 (N=598) were analysed. Results: One and a half years after graduating 53% of those interviewed had completed their doctorate. When asked about their motivation for writing a doctoral thesis, participants answered most frequently “a doctorate is usual” (85%) and “improvement of job opportunities” (75%), 36% said that an academic career has been their primary motive. Less than 10% responded that they used their doctoral thesis as a means to apply for a job. The proportion of graduates working in health care is equally large among those who have completed a thesis and those who have not. Graduates who pursued a thesis due to scientific interest are also currently more interested in an academic career and recognise more opportunities for research. An implicit benefit of a medical thesis emerged with regard to the self-assessment of scientific competences as those who completed a doctorate rated their scientific competencies higher than those who have not. Discussion: Although for the majority of physicians research interest is not the primary motivation for completing a doctorate, they might nevertheless achieve some academic competencies. For graduates pursuing an academic career the benefit of completing a medical thesis is more obvious. PMID:26958656

The assessment of factors associated with return to work (RTW) after multiple trauma is important in trauma research. Goals in rehabilitation should comprise RTW. The purpose of this study was to examine the RTW rate and which factors predicted RTW for patients with severe multiple injuries using a prospective cohort design. In all, 100 patients with a New Injury Severity Score (NISS) >15, aged 18 to 67 years and admitted to a trauma referral center, were included starting January 2002 through June 2003. Outcomes were assessed 6 weeks after discharge and 1 and 2 years postinjury. Instruments were the Brief Approach/Avoidance Coping Questionnaire, Multidimensional Health Locus of Control, Short Form-36, the World Health Organization Disability Assessment Schedule II, and a cognitive function scale (COG). Mean age was 34.5 years (SD 13.5), 83% were male, and 66% were blue-collar workers. Mean NISS was 35.1 (SD 12.7). At 1 year, 28% achieved complete RTW, 43% at 2 years. Mean time back to work was 12.8 months (SD 5.9). Differences between the RTW and not complete RTW (NRTW) groups concerned personal and demographic variables, and physical and psychosocial functioning. Survival analysis showed that risk factors for NRTW were lower education, length of stay in hospital/rehabilitation >20 weeks, and low social functioning shortly after the return home. The majority of the patients had not completely returned to work 2 years postinjury. Demographic and injury related factors and social functioning were significant predictors of RTW status.

Status of NASA's Space Launch System

NASA's Space Launch System (SLS) continued to make significant progress in 2015 and 2016, completing hardware and testing that brings NASA closer to a new era of deep space exploration. Programmatically, SLS completed Critical Design Review (CDR) in 2015. A team of independent reviewers concluded that the vehicle design is technically and programmatically ready to move to Design Certification Review (DCR) and launch readiness in 2018. Just five years after program start, every major element has amassed development and flight hardware and completed key tests that will lead to an accelerated pace of manufacturing and testing in 2016 and 2017. Key to SLS' rapid progress has been the use of existing technologies adapted to the new launch vehicle. The existing fleet of RS-25 engines is undergoing adaptation tests to prove it can meet SLS requirements and environments with minimal change. The four-segment shuttle-era booster has been modified and updated with a fifth propellant segment, new insulation, and new avionics. The Interim Cryogenic Upper Stage is a modified version of an existing upper stage. The first Block I SLS configuration will launch a minimum of 70 metric tons (t) of payload to low Earth orbit (LEO). The vehicle architecture has a clear evolutionary path to more than 100t and, ultimately, to 130t. Among the program's major 2015-2016 accomplishments were two booster qualification hotfire tests, a series of RS-25 adaptation hotfire tests, manufacturing of most of the major components for both core stage test articles and first flight tank, delivery of the Pegasus core stage barge, and the upper stage simulator. Renovations to the B-2 test stand for stage green run testing was completed at NASA Stennis Space Center. This year will see the completion of welding for all qualification and flight EM-1 core stage components and testing of flight avionics, completion of core stage structural test stands, casting of the EM-1 solid rocket motors, additional testing of RS-25 engines and flight engine controllers This paper will discuss these and other technical and programmatic successes and challenges over the past year and provide a preview of work ahead before the first flight of this new capability.

The service life assessment for NASA's Evolutionary Xenon Thruster is updated to incorporate the results from the successful and voluntarily early completion of the 51,184 hour long duration test which demonstrated 918 kg of total xenon throughput. The results of the numerous post-test investigations including destructive interrogations have been assessed against all of the critical known and suspected failure mechanisms to update the life and throughput expectations for each major component. Analysis results of two of the most acute failure mechanisms, namely pit-and-groove erosion and aperture enlargement of the accelerator grid, are not updated in this work but will be published at a future time after analysis completion.

The missing women in STEM? Assessing gender differentials in the factors associated with transition to first jobs.

Women remain underrepresented in the STEM workforce. We assess explanations for women's underrepresentation in STEM jobs, focusing on a cohort that came of age in the 1980s and 1990s, when women dramatically increased their representation in the scientific labor force. Data are from the NLSY79, and our analysis focuses on members of this cohort who received a college degree, with an emphasis on those who completed a degree in a STEM field. Our analyses test the extent to which college major, expectations to work in STEM, and family expectations shaped transitions into STEM occupations within two years of degree completion. Among those majoring in STEM fields there were no gender differences in transitioning into STEM jobs, though there were sizable differences in transitions to STEM employment by field of study. Of note are gender differences in associations between family expectations and transitions into STEM employment. The most career oriented women, who expected to marry late and limit fertility, were no more likely to enter STEM jobs than were women who anticipated marrying young and having two or more children. The men most likely to enter STEM occupations, in contrast, adhered to significantly more conventional gender ideologies than their female counterparts, expecting to marry at younger ages but also to remain childless. Results of our regression decomposition indicated that marriage and family expectations and gender ideology worked in opposite directions for men and women. Nonetheless, the majority of the gender disparity in transitions into STEM jobs was related to women's underrepresentation in engineering and computer science fields of study.

Williamson, Ann; Friswell, Rena

2013-09-01

The aim of this study was to explore the effects of external influences on long distance trucking, in particular, incentive-based remuneration systems and the need to wait or queue to load or unload on driver experiences of fatigue. Long distance truck drivers (n=475) were recruited at truck rest stops on the major transport corridors within New South Wales, Australia and asked to complete a survey by self-administration or interview. The survey covered demographics, usual working arrangements, details of the last trip and safety outcomes including fatigue experiences. On average drivers' last trip was over 2000 km and took 21.5 h to complete with an additional 6h of non-driving work. Incentive payments were associated with longer working hours, greater distances driven and higher fatigue for more drivers. Drivers required to wait in queues did significantly more non-driving work and experienced fatigue more often than those who did not. Drivers who were not paid to wait did the longest trips with average weekly hours above the legal working hours limits, had the highest levels of fatigue and the highest levels of interference by work with family life. In contrast, drivers who were paid to wait did significantly less work with shorter usual hours and shorter last trips. Multivariate analysis showed that incentive-based payment and unpaid waiting in queues were significant predictors of driver fatigue. The findings suggest that mandating payment of drivers for non-driving work including waiting would reduce the amount of non-driving work required for drivers and reduce weekly hours of work. In turn this would reduce driver fatigue and safety risk as well as enhancing the efficiency of the long distance road transport industry. Copyright © 2013 Elsevier Ltd. All rights reserved.

Objective To examine the productivity of patients with scleroderma (SSc) both outside and within the home in a large observational cohort. Methods 162 patients completed the Work Productivity Survey. Patients indicated whether or not they were employed outside of the home, how many days/month they missed work (employment or household work) due to SSc and how many days/month productivity was decreased ≥ 50%. Patients also completed other patient-reported outcome measures. We developed binomial regression models to assess the predictors of days missed from work (paid employment or household activities). The covariates included: type of SSc, education, physician and patient global assessments, HAQ-DI, FACIT-Fatigue, and Center of Epidemiologic Studies Depression Scale – Short Form (CESD). Results The average age of patients was 51.8 years and 51% had limited SSc. Of 37% patients employed outside of the home, patients reported missing 2.6 days/month of work and had 2.5 days per month productivity reduced by half. Of the 102 patients who were not employed, 39.4% were unable to work due to their SSc. When we assessed patients for household activities (N = 162), patients missed an average of 8 days of housework/month and had productivity reduced by average of 6 days/month. In the regression models, patients with lower education and poor assessment of overall health by physician were more likely to miss work outside the home. Patients with limited SSc and high HAQ-DI were more likely to miss work at home. Conclusion SSc has a major impact on productivity at home and at work. Nearly 40% of patients reported disability due to their SSc. PMID:22012885

Bringing the science of proteins into the realm of organic chemistry: total chemical synthesis of SEP (synthetic erythropoiesis protein).

Erythropoietin, commonly known as EPO, is a glycoprotein hormone that stimulates the production of red blood cells. Recombinant EPO has been described as "arguably the most successful drug spawned by the revolution in recombinant DNA technology". Recently, the EPO glycoprotein molecule has re-emerged as a major target of synthetic organic chemistry. In this article I will give an account of an important body of earlier work on the chemical synthesis of a designed EPO analogue that had full biological activity and improved pharmacokinetic properties. The design and synthesis of this "synthetic erythropoiesis protein" was ahead of its time, but has gained new relevance in recent months. Here I will document the story of one of the major accomplishments of synthetic chemistry in a more complete way than is possible in the primary literature, and put the work in its contemporaneous context.

2011-12-01

Self-passivating tungsten-based alloys are expected to provide a major safety advantage compared to pure tungsten, which is at present the main candidate material for the first wall armour of future fusion reactors. WC10Si10 alloys were manufactured by mechanical alloying (MA) in a Planetary mill and subsequent hot isostatic pressing (HIP), achieving densities above 95%. Different MA conditions were studied. After MA under optimized conditions, a core with heterogeneous microstructure was found in larger powder particles, resulting in the presence of some large W grains after HIP. Nevertheless, the obtained microstructure is significantly refined compared to previous work. First MA trials were also performed on the Si-free system WCr12Ti2.5. In this case a very homogeneous structure inside the powder particles was obtained, and a majority ternary metastable bcc phase was found, indicating that almost complete alloying occurred. Therefore, a very fine and homogeneous microstructure can be expected after HIP in future work.

With NASA's commitment to the International Space Station (ISS) now all but certain for at least through the coming decade, serious consideration may be given to extended US in-space operations in the 2020s, when presumably the ISS will exceed its sell by date. Indeed, both ESA and Roscosmos, in addition to their unambiguous current commitment to ISS, have published early concept studies for extended post-ISS habitation (e.g., http://www.esa.int/esaHS/index.html, http://www.russianspaceweb.com/opsek.html and references therein). In the US, engineers and scientists have for a decade been working both within and outside NASA to assess one consistent candidate for long-term post-ISS habitation and operations, although interrupted by changing priorities for human space flight, Congressional direction, and constrained budgets. The evolving work of these groups is described here, which may have renewed relevance with the recent completion of a major review of the nation s human space flight program.

Multiple Sclerosis (MS) is the most common cause of neurological disability in young and middle-aged adults. At this stage in life most people are in the midst of their working career. The majority of MS patients are unable to retain employment within 10 years from disease onset. Leading up to unemployment, many may experience a reduction in hours or work responsibilities and increased time missed from work. The MS@Work study examines various factors that may influence work participation in relapsing-remitting MS patients, including disease-related factors, the working environment and personal factors. The MS@Work study is a multicenter, 3-year prospective observational study on work participation in patients with relapsing-remitting MS. We aim to include 350 patients through 15-18 MS outpatient clinics in the Netherlands. Eligible participants are 18 years and older, and either currently employed or within three years since their last employment. At baseline and after 1, 2 and 3 years, the participants are asked to complete online questionnaires (including questions on work participation, work problems and accommodations, cognitive and physical ability, anxiety, depression, psychosocial stress, quality of life, fatigue, empathy, personality traits and coping strategies) and undergo cognitive and neurological examinations. After six months, patients are requested to only complete online questionnaires. Patient perspectives on maintaining and improving work participation and reasons to stop working are gathered through semi-structured interviews in a sub-group of patients. Prospective studies with long-term follow-up on work participation in MS are rare, or take into account a limited number of factors. The MS@Work study provides a 3-year follow-up on various factors that may influence work participation in patients with relapsing-remitting MS. We aim to identify factors that relate to job loss and to provide information about preventative measures for physicians, psychologists and other professionals working in the field of occupational health.

in Germany psychology students can be seen as the major personal resource in psychotherapy. Nevertheless there are few studies on their vocational plans and their interest in psychotherapeutic training. 480 psychology students completed a self-developed questionnaire on their career expectations. 90% of respondents report interest in clinical work and psychotherapeutic training. Most frequently they mention improving therapeutic competencies and career options as pros and current training requirements as cons. Their theoretical orientation (38% behaviour therapy, 19% psychodynamic therapy) is associated with their psychotherapeutic knowledge, study conditions and respondent's characteristics. psychology students consider working and training conditions for psychologists and psychotherapists, when thinking about their future career.

Oral health in childhood is a major problem for global public health. In Brazil, the prevalence of childhood tooth decay varies from 12% to 46%. Dental care treatment in Brazil is almost the exclusive responsibility of primary healthcare (PHC). Therefore, it is essential these professionals are prepared to conduct restorative, endodontic, and exodontic treatments and preventive care in children. Children make up a large proportion of the population in territories requiring advanced dental care provided by PHC in Brazil. To care for these patients, it is necessary to have both manual dexterity and technical knowledge of pediatric dentistry. Accordingly, this study aimed to develop a distance course on pediatric dentistry. A pretest questionnaire consisting of 15 questions was used to assess initial dental knowledge of participants. After completion of a five-module course, participants retook the same initial dental knowledge questionnaire (post-test). Descriptive statistic and paired t test, one-way analysis of variance, and Pearson and Spearman correlation were used, and a significance level of 5% was set. The majority of participants completing the five-module course were women who earned specialty degrees beyond undergraduate studies and currently worked in PHC (>5 years). Participant performance on the dental knowledge questionnaire after completion of the five-module course improved pre- to post-test. These data suggest that completion of a distance course on pediatric dentistry can be an effective tool for improving knowledge of pediatric dentistry in PHC professionals.

Trial registries are a key source of information for clinicians and researchers. While building OpenTrials, an open database of public trial information, we identified errors and omissions in registries, including discrepancies between descriptions of the same trial in different registries. We set out to ascertain the prevalence of discrepancies in trial completion status using a cohort of trials registered on both the European Union Clinical Trials Register (EUCTR) and ClinicalTrials.gov. We used matching titles and registry IDs provided by both registries to build a cohort of dual-registered trials. Completion statuses were compared; we calculated descriptive statistics on the prevalence of discrepancies. 11,988 dual-registered trials were identified. 1,496 did not provide a comparable completion status, leaving 10,492 trials. 16.2% were discrepant on completion status. The majority of discrepancies (90.5%) were a 'completed' trial on ClinicalTrials.gov inaccurately marked as 'ongoing' on EUCTR. Overall, 33.9% of dual-registered trials described as 'ongoing' on EUCTR were listed as 'completed' on ClinicalTrials.gov. Completion status on registries is commonly inaccurate. Previous work on publication bias may underestimate non-reporting. We describe simple steps registry owners and trialists could take to improve accuracy.

LSST telescope and site status

NASA Astrophysics Data System (ADS)

Gressler, William J.

2016-07-01

The Large Synoptic Survey Telescope (LSST) Project1 received its construction authorization from the National Science Foundation in August 2014. The Telescope and Site (T and S) group has made considerable progress towards completion in subsystems required to support the scope of the LSST science mission. The LSST goal is to conduct a wide, fast, deep survey via a 3-mirror wide field of view optical design, a 3.2-Gpixel camera, and an automated data processing system. The summit facility is currently under construction on Cerro Pachón in Chile, with major vendor subsystem deliveries and integration planned over the next several years. This paper summarizes the status of the activities of the T and S group, tasked with design, analysis, and construction of the summit and base facilities and infrastructure necessary to control the survey, capture the light, and calibrate the data. All major telescope work package procurements have been awarded to vendors and are in varying stages of design and fabrication maturity and completion. The unique M1M3 primary/tertiary mirror polishing effort is completed and the mirror now resides in storage waiting future testing. Significant progress has been achieved on all the major telescope subsystems including the summit facility, telescope mount assembly, dome, hexapod and rotator systems, coating plant, base facility, and the calibration telescope. In parallel, in-house efforts including the software needed to control the observatory such as the scheduler and the active optics control, have also seen substantial advancement. The progress and status of these subsystems and future LSST plans during this construction phase are presented.

Nicol, M. F.; Johnson, M.; Koumvakalis, A. S.

1984-01-01

Progress is reported on a project to determine the properties and boundaries of high pressure phases of the H2-He-H2O-NH3-CH4 system that are needed to constrain theoretical models of the interiors of the major planets. This project is one of the first attempts to measure phase equilibria in binary fluid-solid systems in diamond anvil cells. Vibrational spectroscopy, direct visual observations, and X-ray diffraction crystallography of materials confined in externally heated cells are the primary experimental probes. Adiabats of these materials are also measured in order to constrain models of heat flow in these bodies and to detect phase transitions by thermal anomalies. Initial efforts involve the NH3-H2O binary. This system is especially relevant to models for surface reconstruction of the icy satellites of Jupiter and Saturn. Thermal analysis experiments were completed for the P-X space, p4GPa:0 or = 0.50, near room temperature. The cryostat, sample handling equipment, and optics needed to extend the optical P-T-X work below room temperature was completed.

Decrements in cognitive function are a common feature of Major Depressive Disorder (MDD), and whether distinct classes of antidepressants differentially affect memory in these individuals has not been sufficiently evaluated. In this study we sought to determine the effect of escitalopram and bupropion XL on memory and psychosocial function. Forty-one individuals (18-50 years) with MDD were enrolled in an 8-week, double-blind, double-dummy, randomized controlled comparative trial of bupropion XL and escitalopram. Thirty-six participants completed pre and post memory assessments. Verbal, non-verbal and working memory were evaluated with a comprehensive neuropsychological battery. Psychosocial function was assessed with the Sheehan Disability Scale and Endicott Work Productivity Scale. Escitalopram and bupropion XL significantly improved immediate as well as delayed verbal and nonverbal memory, global function (all p≤0.001), and work productivity (p=0.045), with no significant between-group differences. Improvement in immediate verbal memory exerted a direct influence on improvement in global function (p=0.006). Treatment with either escitalopram or bupropion XL was associated with improvement in memory and psychosocial function in adults with MDD. Copyright © 2014. Published by Elsevier Ireland Ltd.

The paper discusses the following: 1. No-cost Extension. The no-cost extension is required to complete the work on the unified model codes (both hydrodynamic and kinetic Monte Carlo) as described in the initial proposal and previous annual reports. 2. Scientific Accomplishments during the Report Period. We completed a comprehensive model of Alfvtn wave reflection that spans the full distance from the photosphere to the distant heliosphere. 3. Comparison of Accomplishments with Proposed Goals. The proposal contained two specific objectives for Year 3: (1) to complete the unified model code, and (2) to apply it to various kinds of coronal holes (and polar plumes within coronal holes). Although the anticipated route toward these two final goals has changed (see accomplishments 2a and 2b above), they remain the major milestones for the extended period of performance. Accomplishments la and IC were necessary prerequisites for the derivation of "physically relevant transport and mode-coupling terms" for the unified model codes (as stated in the proposal Year 3 goals). We have fulfilled the proposed "core work" to study 4 general types of physical processes; in previous years we studied turbulence, mode coupling (Le., non-WKB reflection), and kinetic wave damping, and accomplishment lb provides the fourth topic: nonlinear steepening.

The purpose of this study was to investigate the relationships among the factors that influence return to work for young individuals with mild stroke from different socioeconomic backgrounds. Prospective cohort study of working adults with mild stroke (N = 21). Participants completed an assessment battery of cognitive, work environment and work performance measures at approximately 3 weeks and 7 months post mild stroke. Individuals were placed in "skilled" and "unskilled" worker categories based on the Hollingshead Index. Unskilled workers had significantly poorer scores on the majority of the cognitive assessments. Unskilled workers also perceived less social support (p = 0.017) and autonomy (p = 0.049) in work responsibilities than individuals in the skilled worker group and also reported significantly poorer work productivity due to stroke than those in the skilled group (p = 0.015). Individuals from low socioeconomic backgrounds have more difficulty returning to work following mild stroke than individuals from higher socioeconomic backgrounds. Future work is needed to identify factors that can increase long-term work success and quality of work performance following a mild stroke that specifically targets the needs of individuals who have a lower socioeconomic status.

Registered nurses' attitudes towards the role of the healthcare assistant.

PubMed

Alcorn, Jason; Topping, Anne Elizabeth

To elicit the views of registered nurses (RNs), working in the surgical directorate of an acute NHS trust, concerning the responsibilities of RNs to healthcare assistants (HCAs), specifically in relation to delegation, development and accountability. A survey using a 24-item questionnaire and a six-point Likert scale design was administered to a convenience sample of 219 RNs working within the surgical directorate. A total of 148 completed questionnaires were returned, giving a 68% response rate. The results suggested that the majority of RNs were aware of their responsibilities regarding accountability for delegated tasks, believe that HCAs should be regulated and, once prepared adequately, held individually accountable for their actions. RNs should undertake appropriate skill development in pre-registration programmes and be provided with preceptorship to ensure they are equipped adequately to supervise and delegate work to HCAs.

Efficient Memory Access with NumPy Global Arrays using Local Memory Access

Daily, Jeffrey A.; Berghofer, Dan C.

This paper discusses the work completed working with Global Arrays of data on distributed multi-computer systems and improving their performance. The tasks completed were done at Pacific Northwest National Laboratory in the Science Undergrad Laboratory Internship program in the summer of 2013 for the Data Intensive Computing Group in the Fundamental and Computational Sciences DIrectorate. This work was done on the Global Arrays Toolkit developed by this group. This toolkit is an interface for programmers to more easily create arrays of data on networks of computers. This is useful because scientific computation is often done on large amounts of datamore » sometimes so large that individual computers cannot hold all of it. This data is held in array form and can best be processed on supercomputers which often consist of a network of individual computers doing their computation in parallel. One major challenge for this sort of programming is that operations on arrays on multiple computers is very complex and an interface is needed so that these arrays seem like they are on a single computer. This is what global arrays does. The work done here is to use more efficient operations on that data that requires less copying of data to be completed. This saves a lot of time because copying data on many different computers is time intensive. The way this challenge was solved is when data to be operated on with binary operations are on the same computer, they are not copied when they are accessed. When they are on separate computers, only one set is copied when accessed. This saves time because of less copying done although more data access operations were done.« less

Advance Directives in Hospice Healthcare Providers: A Clinical Challenge.

On a daily basis, healthcare providers, especially those dealing with terminally ill patients, such as hospice workers, witness how advance directives help ensure the wishes of patients. They also witness the deleterious consequences when patients fail to document the care they desire at their end of life. To the best of our knowledge there are no data concerning the prevalence of advance directives among hospice healthcare providers. We therefore explored the prevalence and factors influencing completion rates in a survey of hospice healthcare providers. Surveys that included 32 items to explore completion rates, as well as barriers, knowledge, and demographics, were e-mailed to 2097 healthcare providers, including employees and volunteers, at a nonprofit hospice. Of 890 respondents, 44% reported having completed an advance directive. Ethnicity, age, relationship status, and perceived knowledge were all significant factors influencing the completion rates, whereas years of experience or working directly with patients had no effect. Procrastination, fear of the subject, and costs were common reasons reported as barriers. Upon completion of the survey, 43% said they will now complete an advance directive, and 45% will talk to patients and families about their wishes. The majority of hospice healthcare providers have not completed an advance directive. These results are very similar to those for other healthcare providers treating patients with terminal diseases, specifically oncologists. Because, at completion, 43% said that they would now complete an advance directive, such a survey of healthcare providers may help increase completion rates. Copyright © 2017 Elsevier Inc.

A new concept for the exploration of Europa.

Rampelotto, Pabulo Henrique

2012-06-01

The Europa Jupiter System Mission (EJSM) is the major Outer Planet Flagship Mission in preparation by NASA. Although well designed, the current EJSM concept may present problematic issues as a Flagship Mission for a long-term exploration program that will occur over the course of decades. For this reason, the present work reviews the current EJSM concept and presents a new strategy for the exploration of Europa. In this concept, the EJSM is reorganized to comprise three independent missions focused on Europa. The missions are split according to scientific goals, which together will give a complete understanding of the potential habitability of Europa, including in situ life's signal measurements. With this alternative strategy, a complete exploration of Europa would be possible in the next decades, even within a politically and economically constrained environment.

To investigate factors affecting the internal brain drain of healthcare professionals in the Kingdom of Saudi Arabia. A cross-sectional study was conducted using an anonymous self-administered online questionnaire sent to all Saudi students enrolled in healthcare profession programs in North America. The data was collected between January and March 2008 at the University of Illinois at Chicago, Chicago, Illinois, United States of America. Results were analyzed using logistic regression analyses. A total of 377 completed questionnaires were returned. Results revealed that 71% of respondents intended to return to work within the 2 major urban cities Riyadh and Jeddah. Respondents who completed their undergraduate studies in a large city were more likely to work in the same city (odds ratio [OR]=3.2; p=0.000; 95% confidence interval [CI] = 2.0-5.2). Furthermore, 51% of the students were willing to work in a rural area for a 50% or more increase in their salary. Finally, men were more willing to work in a rural area for a financial incentive (OR=2.3; p=0.006, 95% CI = 1.3-4.3). This study suggests that realistic financial incentives would probably not suffice to attract Saudi healthcare providers to rural areas. The provision of medical schools in smaller cities and rural areas is predicted to be a more effective method for improving the current maldistribution of healthcare providers.

A study of engineering student attributes and time to completion of first-year required courses at Texas A&M University

NASA Astrophysics Data System (ADS)

Kimball, Jorja Lay

For many years, colleges of engineering across the nation have required that a foundational set of courses be completed for entry into upper division coursework or into a specific engineering major. Since 1998, The Dwight Look College of Engineering at Texas A&M University (TAMU) has required that incoming first-time enrolling students complete a Core Body of Knowledge (CBK) with specific cumulative grade points required for specific majors. However, considerations of the time to completion of coursework and other student characteristics and academic factors have not been taken into consideration by TAMU, like most institutions. The purpose of this study is to determine for first year engineering students at TAMU the relationship of gender, ethnicity, engineering major, unmet financial need, cumulative grade point average, and total transfer hours on time to completion of CBK courses. The results of the analysis showed that cumulative grade point average (CGPA) had the strongest relationship to completion of CBK of any independent variable in this study. Statistical significance was found for the following variables in this study: CGPA, gender, ethnicity, and unmet financial need. For the study's variable of major, statistical significance was found for Chemical, Electrical, and Computer Engineering majors. The one variable in this study that did not show statistical significance in relation to time to completion of CBK was transfer credit. Findings with implications for recruitment and retention of underrepresented in engineering is a statistical significance indicating that on average females are taking less time than males to complete CBK. The conclusion from the study is that efforts to attract more women into engineering have merit as do programs to support underrepresented students in order that they may complete CBK at a faster pace. Further study to determine profiles of those majors where statistical significance was found for students taking a greater or lesser amount of time for CBK completion than the mean is recommended, as is ongoing data collection and comparison for current cohorts of engineering majors at TAMU.

Very preterm children exhibit difficulties in working memory, a key cognitive ability vital to learning information and the development of academic skills. Previous research suggests that an adaptive working memory training intervention (Cogmed) may improve working memory and other cognitive and behavioural domains, although further randomised controlled trials employing long-term outcomes are needed, and with populations at risk for working memory deficits, such as children born preterm.In a cohort of extremely preterm (<28 weeks' gestation)/extremely low birthweight (<1000 g) 7-year-olds, we will assess the effectiveness of Cogmed in improving academic functioning 2 years' post-intervention. Secondary objectives are to assess the effectiveness of Cogmed in improving working memory and attention 2 weeks', 12 months' and 24 months' post-intervention, and to investigate training related neuroplasticity in working memory neural networks 2 weeks' post-intervention. This double-blind, placebo-controlled, randomised controlled trial aims to recruit 126 extremely preterm/extremely low birthweight 7-year-old children. Children attending mainstream school without major intellectual, sensory or physical impairments will be eligible. Participating children will undergo an extensive baseline cognitive assessment before being randomised to either an adaptive or placebo (non-adaptive) version of Cogmed. Cogmed is a computerised working memory training program consisting of 25 sessions completed over a 5 to 7 week period. Each training session takes approximately 35 minutes and will be completed in the child's home. Structural, diffusion and functional Magnetic Resonance Imaging, which is optional for participants, will be completed prior to and 2 weeks following the training period. Follow-up assessments focusing on academic skills (primary outcome), working memory and attention (secondary outcomes) will be conducted at 2 weeks', 12 months' and 24 months' post-intervention. To our knowledge, this study will be the first randomised controlled trial to (a) assess the effectiveness of Cogmed in school-aged extremely preterm/extremely low birthweight children, while incorporating advanced imaging techniques to investigate neural changes associated with adaptive working memory training, and (b) employ long-term follow-up to assess the potential benefit of improved working memory on academic functioning. If effective, Cogmed would serve as a valuable, available intervention for improving developmental outcomes for this population. Australian New Zealand Clinical Trials Registry ACTRN12612000124831.

The author has identified the following significant results. Most major vegetation types of Nevada have been mapped with success. The completed set of mosaic overlays will be more accurate and detailed than previous maps compiled by various State and Federal agencies due to the excellent vantage point that ERTS-1 data affords. This new vegetation type map will greatly aid resource agencies in their daily work. Such information as suitable grazing areas, wildlife habitat, forage production, and approximate wildland production potentials can be inferred from such a map. There has been some success in detecting vegetational changes with the use of ERTS-1 MSS imagery, but exposure differences have somewhat confounded the results. Future plans include work to solve this problem.

NASA's Space Launch System (SLS) continued to make significant progress in 2015, completing hardware and testing that brings NASA closer to a new era of deep space exploration. The most significant program milestone of the year was completion of Critical Design Review (CDR). A team of independent reviewers concluded that the vehicle design is technically and programmatically ready to move to Design Certification Review (DCR) and launch readiness in 2018. Just four years after program start, every major element has amassed development and flight hardware and completed key tests that will set the stage for a growing schedule of manufacturing and testing in 2016. Key to SLS' rapid progress has been the use of existing technologies adapted to the new launch vehicle. The space shuttle-heritage RS-25 engine is undergoing adaptation tests to prove it can meet SLS requirements and environments with minimal change. The four-segment shuttle-era booster has been modified and updated with an additional propellant segment, new insulation, and new avionics. The Interim Cryogenic Upper Stage is a modified version of an existing upper stage. The first Block I SLS configuration will launch a minimum of 70 metric tons of payload to low Earth orbit (LEO). The vehicle architecture has a clear evolutionary path to more than 100 metric tons and, ultimately, to 130 metric tons. Among the program's major accomplishments in 2015 were the first booster qualification hotfire test, a series of seven RS-25 adaptation hotfire tests, manufacturing of most of the major components for both core stage test articles and first flight tank, delivery of the Pegasus core stage barge, and the upper stage simulator. Renovations to the B-2 test stand for stage green run testing was completed at NASA Stennis Space Center. This year will see the second booster qualification motor hotfire, flight and additional development RS-25 engine tests, and completion of core stage test articles and test stands and several flight article sections. This paper will discuss these and other technical and programmatic successes and challenges over the past year and provide a preview of work ahead before the first flight of this new capability.

The Interim Cryogenic Upper Stage is a modified version of an existing upper stage. The first Block I SLS configuration will launch a minimum of 70 metric tons (t) of payload to low Earth orbit (LEO). The vehicle architecture has a clear evolutionary path to more than 100t and, ultimately, to 130t. Among the program's major accomplishments in 2015 were the first booster qualification hotfire test, a series of seven RS-25 adaptation hotfire tests, manufacturing of most of the major components for both core stage test articles and first flight tank, delivery of the Pegasus core stage barge, and the upper stage simulator. Renovations to the B-2 test stand for stage green run testing was completed at NASA Stennis Space Center. This year will see the second booster qualification motor hotfire, flight and additional development RS-25 engine tests, and completion of core stage test articles and test stands and several flight article sections. This paper will discuss these and other technical and programmatic successes and challenges over the past year and provide a preview of work ahead before the first flight of this new capability.

Risk factors for postpartum depression in euthymic pregnant women with histories of major depressive disorder (MDD) were evaluated. From April 2003 to March 2009, 343 pregnant women with a history of Structured Clinical Interview for DSM-IV (SCID)-diagnosed major depressive disorder were prospectively assessed from the third trimester into the postpartum period using the SCID mood module and 17-item Hamilton Depression Rating Scale (HDRS). Data from 300 subjects who completed at least 2 mood module assessments (1 within 60 days before and the other within 60 days after delivery) were analyzed for predictive associations between variables assessed in the third trimester and the development of a postpartum depression. The majority of women were euthymic in pregnancy by SCID criteria. Women with third trimester SCID-diagnosed depression (n = 45) versus euthymia (n = 255) had a significantly higher risk for having depression after delivery (24% vs 11%, P = .013). For pregnant euthymic women, third trimester total HDRS scores significantly predicted postpartum depression (P < .0001); specifically, scores on 3 HDRS items alone-work activities, early insomnia, and suicidality-significantly predicted postpartum depression. Antidepressant use in the third trimester in euthymic women did not confer protection against the onset of postpartum depression. Among women with a history of MDD who are euthymic in the third trimester, 3 HDRS items-work activities, early insomnia, and suicidality-may be useful as screening items for clinicians working with pregnant women with histories of MDD to identify a group at risk for developing postpartum depression. Additionally, in euthymic women with a history of MDD, antidepressant use in the third trimester may not reduce the risk of developing postpartum depression. © Copyright 2017 Physicians Postgraduate Press, Inc.

Factors Influencing Clinical Performance of Baccalaureate Nursing Majors: A Retrospective Audit.

PubMed

Johnston, Sandra; Fox, Amanda; Coyer, Fiona Maree

2018-06-01

Transition of nursing student to new graduate depends on successful completion of clinical work placement during an undergraduate course. Supporting students during the clinical placement is imperative. This study examined associations between grade point average, domestic or international status, course entry qualification, and single or dual nursing degree to successful completion of clinical placement. A retrospective audit of 665 students in a baccalaureate nursing program was conducted to examine factors influencing clinical performance of baccalaureate nursing students. A significant association between entry qualification, lower grade point average, international status, and receipt of a constructive note was found: χ 2 = 8.678, df = 3, p = .034, t(3.862), df = 663, p ⩽ .001, and Fisher's exact test = 8.581, df = 1, p = .003, respectively. Understanding factors that affect clinical performance may help early identification of students at risk and allow for supportive intervention during placement and subsequent program completion.

Work and family role juggling and mood states of Hong Kong public health nurses with children.

PubMed

Shiu, A T

1998-07-01

This study aims to investigate the daily mood states of public health nurses (PHNs) in managerial roles with children in Hong Kong, as a result of multiple role juggling (i.e. simultaneously attending to demands of different roles) using the experience sampling method. Convenience sampling was used to recruit 20 subjects. A watch was worn that beeped at six random times each day for 7 days as a signal to complete an experience sampling diary. PHNs on average responded to 34 signals (80%) to complete the experience sampling diaries. Two major findings provide the focus of this paper. First, results show that PHNs had minimal inter-role juggling between work and family as compared with previous studies in the United States. Cultural factors, sequentially dealing with family and work issues, having a domestic maid or a relative to see to household chores as well as strong spouse support are suggested as the reasons. These results have implications for nursing management and nursing practice. Second, the results also reveal PHNs as having an overall flat affect. It is suggested that PHNs may be using a 'calm and detached' coping style for occupational stress. This coping style has implications on the PHNs' emotional health as well as nurse-client relationships.

Postmenopausal estradiol therapy (ET) can reduce the stress response. However, it remains unclear whether such reductions can mitigate effects of stress on cognition. Investigate effects of ET on cortisol response to a physical stressor, cold pressor test (CPT), and whether ET attenuates stress effects on working memory. Women completed the CPT or control condition across two sessions and subsequently completed a sentence span task. General community: Participants were recruited from the Early vs Late Intervention Trial with Estradiol (ELITE). ELITE participants (mean age = 66, standard deviation age = 6.8) in this study did not suffer from any major chronic illness or use medications known to affect the stress response or cognition. Participants had received a median of randomized 4.7 years of estradiol (n = 21) or placebo (n = 21) treatment at time of participation in this study. Salivary cortisol and sentence span task performance. Women assigned to estradiol exhibited blunted cortisol responses to CPT compared with placebo (P = 0.017) and lesser negative effects of stress on working memory (P = 0.048). We present evidence suggesting ET may protect certain types of cognition in the presence of stress. Such estrogenic protection against stress hormone exposure may prove beneficial to both cognition and the neural circuitry that maintains and propagates cognitive faculties.

Experiences and psychological distress of fertility treatment and employment.

PubMed

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

2018-04-16

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

This study examined the loss of productivity and health risk status associated with employees who provide care for an ill dependent. A total of 16,651 employees (23% response rate) of a major financial services company completed a confidential Health Risk Appraisal (HRA) that included an eight-item version of the Work Limitations Questionnaire and a self-report of time missed from work during the previous 2 weeks to care for an ill dependent. A total of 10.6% of the respondents reported an average of 7.7 hours absent from work during the previous 2-week period to provide care for an ill dependent. Caregiving also was associated with a significant increase in the number of health risks for the employee. As the demand for caregiving time increased, caregivers reported a significant increase in work limitations. Caregiving for an ill dependent is associated with increased absenteeism and significant work limitations while on the job. Programs and work organization that helps employees balance their caregiving responsibilities for ill dependents may have a positive effect on health and productivity.

Pricing, costs, financing, and politics are chief among the issues that can impede construction of major, cross-border gas-pipeline projects trying to connect plentiful reserves with unsatisfied market demand. Additionally, strained relationships among parties involved in both supply and delivery can further slow or even halt progress on a project. In the cases of the Transmed (Algeria across Tunisia to Italy) and the Maghreb-Europe (Algeria across Morocco to Spain), the close working relationships of all parties involved helped resolve many issues and were key in the projects` eventual completion.

This paper reports the key findings of the first Faculty of Radiation Oncology survey of trainees dealing with experiences and perceptions on work practices and choice of specialty. The survey was conducted in mid 2012 using a 37-question instrument. This was distributed by email to 159 current trainees and advertised through the Radiation Oncology Trainees Committee and other channels. There were six email reminders. Respondents were reassured that their responses were anonymous. The overall response rate was 82.8%. Gender was balanced among respondents with 67 (51.5%) being male and 63 (48.5%) being female. The most common age bracket was the 31 to 35 years range. There were similar proportions of trainee responders in each of the five years of training. A substantial number of trainees held other degrees besides medical degrees. The large majority were satisfied with radiation oncology as a career choice and with the Training Network within which they were training. Interest in oncology patients, lifestyle after training and work hours were given as the major reasons for choosing radiation oncology as a career. Nearly half of trainees were interested in undertaking some of their training in a part-time capacity and working part time as a radiation oncologist in the future. Over 70% of trainees stated they were working 36-55 clinical hours per week with additional non-clinical tasks, after-hours work and on-call duties. Nearly half of all trainees reported having one or less hours of protected time per week. Nonetheless, 40% of respondents indicated they had enough time to pursue outside interests. Radiation treatment planning and maintaining currency in general medicine were considered the most difficult aspects of training in radiation oncology. Most respondents were keen on the concept of fostering a research mentor. In terms of views on practice after completion of training, the majority were interested in pursuing a fellowship, and nearly all expressed an interest in maintaining an element of academic practice. The large majority of respondents preferred to work in an urban department as a component of their practice after training and nearly all wanted a component of public sector practice. There were only four per cent who preferred to work only within the private sector. Job availability was a concern for 94% of trainees, which far outweighed any other concerns. Trainees in radiation oncology are generally satisfied with their choice of specialty and their training. Most trainees are interested in fellowship positions, links with academia and largely public sector work in the future. Job availability for the future is their major concern. © 2013 The Royal Australian and New Zealand College of Radiologists.

The education sector faces major challenges in providing learning experiences so that newly qualified nurses feel adequately prepared to work in a community setting. With this in mind, higher education institutions need to develop more innovative ways to deliver the community-nurse experience to student nurses. This paper presents and explores how simulation provides an opportunity for educators to support and evaluate student performance in an environment that models a complete patient encounter in the community. Following the simulation, evaluative data were collated and the answers analysed to identify key recommendations.

During the period 2008-2009, there were 2 contracts with BPA. One (38539) was dealing with the restoration work for 2007 and the other (26198) was an extension on the 2006 contract including the NEPA for Dam removal on the old channel of the Sandy River. For contract 38539, the Sandy River Delta Habitat Restoration project continued its focus on riparian hardwood reforestation with less emphasis on wetlands restoration. Emphasis was placed on Sundial Island again due to the potential removal of the dike and the loss of access in the near future. AshCreek Forest Management was able to leverage additionalmore » funding from grants to help finance the restoration effort; this required a mid year revision of work funded by BPA. The revised work not only continued the maintenance of restored hardwood forests, but was aimed to commence the restoration of the Columbia River Banks, an area all along the Columbia River. This would be the final restoration for Sundial Island. The grant funding would help achieve this. Thus by 2011, all major work will have been completed on Sundial Island and the need for access with vehicles would no longer be required. The restored forests continued to show excellent growth and development towards true riparian gallery forests. Final inter-planting was commenced, and will continue through 2010 before the area is considered fully restored. No new wetland work was completed. The wetlands were filled by pumping in early summer to augment the water levels but due to better rainfall, no new fuel was required to augment existing. Monitoring results continued to show very good growth of the trees and the restoration at large was performing beyond expectations. Weed problems continue to be the most difficult issue. The $100,000 from BPA planned for forest restoration in 2008, was augmented by $25,000 from USFS, $120,000 from OR150 grant, $18,000 from LCREP, and the COE continued to add $250,000 for their portion. Summary of the use of these funds are displayed in Table 1 (page 5). Work on the restoration of the original Sandy River channel (dam removal, contract 26198) continued slowly. The draft EA was completed and sent out for review. The COE has decided to finish the NEPA with the intent to complete the project.« less

1973-01-01

Work on Kaufman thruster development completed during the years 1971 and 1972 is reviewed. Thrusters tested have ranged in size from 2.5-cm to 150-cm diameters, in thrust from 0.4 to 4300 mN, and in power from 0.03 to 203 kW. A 2.5-cm thruster was briefly tested and found to have surprisingly high thruster efficiency. Emphasis is placed on thruster system reliability and lifetime as previous work has increased thruster efficiency to a high level. Work also proceeds on definition of thruster-spacecraft interactions. Major R&D efforts are directed at present into two areas of thruster size: a 5-cm to 8-cm diameter thruster to be used for station keeping and attitude control of geosynchronous spacecraft; and a 30-cm diameter thruster to be used for primary propulsion in a 3- to 7-thruster array for solar electric propulsion of interplanetary spacecraft.

Effects of interest-major congruence, motivation, and academic performance on timely degree attainment.

Using longitudinal student data from 15 four-year (n = 3,072) and 13 (n = 788) two-year postsecondary institutions, the authors tested the effects of interest-major congruence, motivation, and 1st-year academic performance on timely degree completion. Findings suggest that interest-major congruence has a direct effect on timely degree completion at both institutional settings and that motivation has indirect effects (via 1st-year academic performance). The total effects of both interest-major congruence and motivation on timely degree completion underscore the importance of both constructs in understanding student adjustment and postsecondary success. Implications for theory and counseling practice are discussed.

Repository-Based Software Engineering Program: Working Program Management Plan

NASA Technical Reports Server (NTRS)

1993-01-01

Repository-Based Software Engineering Program (RBSE) is a National Aeronautics and Space Administration (NASA) sponsored program dedicated to introducing and supporting common, effective approaches to software engineering practices. The process of conceiving, designing, building, and maintaining software systems by using existing software assets that are stored in a specialized operational reuse library or repository, accessible to system designers, is the foundation of the program. In addition to operating a software repository, RBSE promotes (1) software engineering technology transfer, (2) academic and instructional support of reuse programs, (3) the use of common software engineering standards and practices, (4) software reuse technology research, and (5) interoperability between reuse libraries. This Program Management Plan (PMP) is intended to communicate program goals and objectives, describe major work areas, and define a management report and control process. This process will assist the Program Manager, University of Houston at Clear Lake (UHCL) in tracking work progress and describing major program activities to NASA management. The goal of this PMP is to make managing the RBSE program a relatively easy process that improves the work of all team members. The PMP describes work areas addressed and work efforts being accomplished by the program; however, it is not intended as a complete description of the program. Its focus is on providing management tools and management processes for monitoring, evaluating, and administering the program; and it includes schedules for charting milestones and deliveries of program products. The PMP was developed by soliciting and obtaining guidance from appropriate program participants, analyzing program management guidance, and reviewing related program management documents.

Structured Qualitative Research: Organizing “Mountains of Words” for Data Analysis, both Qualitative and Quantitative

2008-01-01

Qualitative research creates mountains of words. U.S. federal funding supports mostly structured qualitative research, which is designed to test hypotheses using semi-quantitative coding and analysis. The authors have 30 years of experience in designing and completing major qualitative research projects, mainly funded by the US National Institute on Drug Abuse [NIDA]. This article reports on strategies for planning, organizing, collecting, managing, storing, retrieving, analyzing, and writing about qualitative data so as to most efficiently manage the mountains of words collected in large-scale ethnographic projects. Multiple benefits accrue from this approach. Several different staff members can contribute to the data collection, even when working from remote locations. Field expenditures are linked to units of work so productivity is measured, many staff in various locations have access to use and analyze the data, quantitative data can be derived from data that is primarily qualitative, and improved efficiencies of resources are developed. The major difficulties involve a need for staff who can program and manage large databases, and who can be skillful analysts of both qualitative and quantitative data. PMID:20222777

Writing a bachelor thesis generates transferable knowledge and skills useable in nursing practice.

Lundgren, Solveig M; Robertsson, Barbro

2013-11-01

Generic skills or transferable skills have been discussed in terms of whether or not skills learned in one context can be transferred into another context. The current study was aimed to explore nurses' self-perceptions of the knowledge and skills they had obtained while writing a Bachelor's thesis in nursing education, their experience of the extent of transfer and utilization in their current work. Responding nurses (N=42) had all worked from 1 to 1.5 years after their final examination and had completed a questionnaire that was structured with open-ended questions. Only five nurses reported that they were unable to use any of the knowledge and skills they had obtained from writing a thesis. A majority of the nurses (37/42) could give many examples of the practical application of the skills and knowledge they had obtained. Our findings indicate that writing a thesis as part of an undergraduate degree program plays a major role in the acquisition and development of knowledge and skills which can subsequently be transferred into and utilized in nursing practice.

Major depressive disorder (MDD) is associated with staggering personal and economic costs, a major proportion of which stem from impaired psychosocial and occupational functioning. Few studies have examined the impact of depression-related cognitive dysfunction on work functioning. We examined the association between neurocognitive and work functioning in employed patients with MDD. Employed adult outpatients (n=36) with MDD of at least moderate severity (≥23 on the Montgomery Asberg Depression Rating Scale, MADRS) and subjective cognitive complaints completed neurocognitive tests (CNS Vital Signs computerized battery) and validated self-reports of their work functioning (LEAPS, HPQ) before and after 8 weeks of open-label treatment with flexibly-dosed desvenlafaxine 50-100mg/day. Relationships between neurocognitive tests and functional measures were examined using bivariate correlational and multiple regression analyses, as appropriate. An ANCOVA model examined whether significant change in neurocognitive performance, defined as improvement of ≥1SD in the Neurocognition Index (NCI) from baseline to post-treatment, was associated with improved outcomes. Patients showed significant improvements in depressive symptom, neurocognitive, and work functioning measures following treatment with desvenlafaxine (e.g., MADRS response=77% and MADRS remission=49%). There were no significant correlations between changes in NCI or cognitive domain subscales and changes in MADRS, LEAPS, or HPQ scores. However, patients demonstrating significant improvement in NCI scores (n=11, 29%) had significantly greater improvement in clinical and work functioning outcomes compared to those without NCI improvement. The limitations of this study include small sample size, lack of a placebo control group, and lack of a healthy comparison group. Our sample also had more years of education and higher premorbid intelligence than the general population. There were no significant correlations between changes in neurocognitive and work functioning measures in this study. However, meaningful improvement in neurocognitive functioning with desvenlafaxine was associated with greater improvement in both mood and occupational outcomes. This suggests that addressing cognitive dysfunction may improve clinical and occupational outcomes in employed patients with MDD. However, the relationship between neurocognitive and work functioning in MDD is complex and requires further study. Copyright © 2016 Elsevier B.V. All rights reserved.

2010-01-01

To ensure the most efficient workplace health promotion it is essential to identify and monitor health conditions of employees and all components of the work process, as well as to recognize their cause-effect relationships. Community nurses form an occupational group with a specific type of workplace that is usually located in the patient's place of residence and thus not inspected in terms of safety and hygiene. The aim of the study was to identify working conditions of community nurses with special reference to occupational hazards. An anonymous questionnaire was used as a major tool of this survey. It contained 33 questions, concerning the work process, working conditions, work loads and arduousness, hazards and work-related complaints. The questionnaire was completed by 86 community nurses working in the Upper Silesia region. Community nurses generally assessed their work as hard. A more thorough analysis revealed that nursing and curative care, nursing and hygienic care and rehabilitation were regarded by community nurses as hard, whereas social diagnostics and curative diagnostics were assessed as much easier tasks. Excessive physical load, forced position at work, aggressive patients, patients' aggressive family members, dangerous domestic animals, low quality of technical devices in patients' homes were reported as the greatest hazards. The obtained results reveal that working conditions of community nurses do not ensure their safety at work.

Abstract It is well recognised that nurse leader managers play an important role in facilitating the quality and nature of hospital care, the improvement of work performance and work satisfaction. In the United Arab Emirates (UAE) they face the additional challenge of working within a context of significant linguistic and cultural diversity where leadership in the provision of culturally competent care is a major requirement. With this goal at the fore, a sample of 153 nurse-leader-managers, including matrons, nursing directors, supervisors, nurses-in-charge and in-service education staff from four private and six government hospitals completed the Multifactor Leadership Questionnaire (Bass & Avolio, 2004). The survey also explored participants' perceptions of the characteristics of good leaders and what they needed to do in their particular work place to enhance culturally competent care. The results showed nurseleader-managers used both transformational and transactional leadership attributes but in different combinations across the two hospital types.

Leiblum, S R; Palmer, M G; Spector, I P

1995-03-01

The purpose of the project was to explore the motivation, reproductive and postdelivery experiences, and future concerns of single heterosexual and lesbian women and lesbian couples who attempted conception via donor insemination (DI). All women who had completed at least one cycle of DI between 1987 and 1992 at a large medical school infertility program were mailed a comprehensive 'Motherhood' questionnaire. Forty-five women completed the survey (response rate = 88%) of whom 14 were lesbians, 28 were heterosexuals, two were bisexual and one was celibate. The only major differences between the heterosexual women and the lesbian women were that the heterosexual women were older and had started DI attempts at an older age than the lesbian women. The majority of women reported that four major considerations prompted their decision to initiate DI when they did: feeling secure in their employment, the sense that time was running out, feeling that they had 'worked through' concerns about parenting, and that they had sufficient social support. Three characteristics were deemed moderately or very important in their selection of sperm donors: ethnicity, education and height. After achieving a pregnancy, most women wished to know more detailed information about their donor. Unlike heterosexual couples, all single and lesbian women planned to disclose the fact of DI to their offspring but were uncertain of when or how to accomplish this. The greatest worry reported by respondents was how their child would deal with the absence of a known designated father. Overall, the women were gratified with their experience of DI, and the majority would 'absolutely' recommend it to a friend.

At-home telemedicine visits are quickly becoming an acceptable alternative for in-person patient visits. However, little work has been done to understand the usability of these home-based telemedicine solutions. It is critical for user acceptance and real-world applicability to evaluate available telemedicine solutions within the context-specific needs of the users of this technology. To address this need, this study evaluated the usability of four home-based telemedicine software platforms: Doxy.me, Vidyo, VSee, and Polycom. Using a within-subjects experimental design, twenty participants were asked to complete a telemedicine session involving several tasks using the four platforms. Upon completion of these tasks for each platform, participants completed the IBM computer system usability questionnaire (CSUQ) and the NASA Task Load Index test. Upon completing the tasks on all four platforms, the participants completed a final post-test subjective questionnaire ranking the platforms based on their preference. Of the twenty participants, 19 completed the study. Statistically significant differences among the telemedicine software platforms were found for task completion time, total workload, mental demand, effort, frustration, preference ranking and computer system usability scores. Usability problems with installation and account creation led to high mental demand and task completion time, suggesting the participants preferred a system without such requirements. Majority of the usability issues were identified at the telemedicine initiation phase. The findings from this study can be used by software developers to develop user-friendly telemedicine systems.

People with Fetal Alcohol Spectrum Disorders (FASD) can be involved in high risk, socially unacceptable and harmful behaviours and are at high risk of engaging with the justice system. To obtain baseline data on Western Australian justice professionals' knowledge, attitudes and practice relating to FASD to inform the development of FASD resources. Cross sectional study using on-line survey methods, descriptive analysis of quantitative data and content analysis methods for qualitative data. 1873 people were invited to complete the survey. A total of 427 (23%) judicial officers, lawyers, corrective services personnel and police completed the survey. The majority had heard of Fetal Alcohol Syndrome (85%) but were less familiar with FASD (60%). Only 16% of respondents identified the key features of FASD as permanent and only 48.4% considered psychological difficulties as important. The majority of legal and judicial officers and approximately half the police officers considered that knowledge about FASD was very relevant to their work. There was widespread agreement of the need for more information and training about FASD to optimise outcomes for people with, or suspected of having a FASD, engaging with the justice system.

Vaccines and future global health needs

Increased international support for both research into new vaccines and their deployment in developing countries has been evident over the past decade. In particular, the GAVI Alliance has had a major impact in increasing uptake of the six common infant vaccines as well as those against hepatitis B and yellow fever. It further aims to introduce pneumococcal and rotavirus vaccines in the near future and several others, including those against human papillomavirus, meningococcal disease, rubella and typhoid not long after that. In addition, there is advanced research into vaccines against malaria, HIV/AIDS and tuberculosis. By 2030, we may have about 20 vaccines that need to be used in the developing world. Finding the requisite funds to achieve this will pose a major problem. A second and urgent question is how to complete the job of global polio eradication. The new strategic plan calls for completion by 2013, but both pre-eradication and post-eradication challenges remain. Vaccines will eventually become available beyond the field of infectious diseases. Much interesting work is being done in both autoimmunity and cancer. Cutting across disease groupings, there are issues in methods of delivery and new adjuvant formulations. PMID:21893548

2018-01-01

To study the prospective areas of upcoming strong-to-major earthquakes, i.e., M w ≥ 6.0, a catalog of seismicity in the vicinity of the Thailand-Laos-Myanmar border region was generated and then investigated statistically. Based on the successful investigations of previous works, the seismicity rate change (Z value) technique was applied in this study. According to the completeness earthquake dataset, eight available case studies of strong-to-major earthquakes were investigated retrospectively. After iterative tests of the characteristic parameters concerning the number of earthquakes ( N) and time window ( T w ), the values of 50 and 1.2 years, respectively, were found to reveal an anomalous high Z-value peak (seismic quiescence) prior to the occurrence of six out of the eight major earthquake events studied. In addition, the location of the Z-value anomalies conformed fairly well to the epicenters of those earthquakes. Based on the investigation of correlation coefficient and the stochastic test of the Z values, the parameters used here ( N = 50 events and T w = 1.2 years) were suitable to determine the precursory Z value and not random phenomena. The Z values of this study and the frequency-magnitude distribution b values of a previous work both highlighted the same prospective areas that might generate an upcoming major earthquake: (i) some areas in the northern part of Laos and (ii) the eastern part of Myanmar.

Background: The importance of increasing the number of US college students completing degrees in science, technology, engineering or mathematics (STEM) has prompted calls for research to provide a better understanding of factors related to student participation in these majors, including the impact of a student's high-school mathematics curriculum. Purpose: This study examines the relationship between various student and high-school characteristics and completion of a STEM major in college. Of specific interest is the influence of a student's high-school mathematics curriculum on the completion of a STEM major in college. Sample: The sample consisted of approximately 3500 students from 229 high schools. Students were predominantly Caucasian (80%), with slightly more males than females (52% vs 48%). Design and method: A quasi-experimental design with archival data was used for students who enrolled in, and graduated from, a post-secondary institution in the upper Midwest. To be included in the sample, students needed to have completed at least three years of high-school mathematics. A generalized linear mixed model was used with students nested within high schools. The data were cross-sectional. Results: High-school predictors were not found to have a significant impact on the completion of a STEM major. Significant student-level predictors included ACT mathematics score, gender and high-school mathematics GPA. Conclusions: The results provide evidence that on average students are equally prepared for the rigorous mathematics coursework regardless of the high-school mathematics curriculum they completed.

The European civilian aviation industry has undergone major changes in the last decade. Despite this, there is little knowledge about work-related stress and subjective health complaints (SHCs) affecting Norwegian aircrew. To investigate the relationships between work-related stress, self-efficacy and SHCs in commercial aircrew in Norway and to explore differences between cockpit and cabin crew. Aircrew members from the three major airlines operating from Norway completed an electronically distributed questionnaire. Linear regression analyses were used to investigate the association between work-related stress, self-efficacy and SHCs. There was a 21% response rate. Among the 843 study subjects, tiredness, sleep problems, bloating, low back pain, headaches and neck pain were the most prevalent SHCs. Cabin crew reported significantly higher numbers, prevalences and mean values for all SHCs compared with cockpit crew (P < 0.05). In total, 20% reported high stress levels. High levels of work-related stress were significantly associated with all SHC factors in both groups. Self-efficacy partly moderated the relationship between stress and psychological complaints in both cockpit and cabin crew, and for musculoskeletal complaints in cockpit crew. The model explained 23 and 32% of the variance in psychological complaints for cockpit and cabin crew, respectively. Commercial aircrew in Norway reported high numbers of SHCs, and high levels of work-related stress were associated with high numbers of SHC. More knowledge is needed on the physical, organizational and psychosocial stressors affecting cockpit and cabin crew in order to create a healthier work environment for these groups. © The Author 2016.

The study aimed to investigate the significance of sense of coherence (SOC) for the perceptions of task characteristics and for stress perceptions during interruptions of public health nurses (PHNs) with children in Hong Kong. The research design employed the experience sampling method. Convenience sampling was used to recruit 20 subjects. During stage one of the study a watch was worn that gave a signal at six random times each day for seven days to complete an experience sampling diary. PHNs on average responded to 34 signals (80%) to complete the diaries which collected data on work and family juggling, task characteristics, and their effects on mood states. At stage two respondents completed the SOC scale which measured confidence in life as comprehensible, manageable, and meaningful. Two major findings provide the focus for this paper. First, results indicate that there was positive correlation between SOC and perceived task characteristics. Second, results reveal that when interruptions occurred, PHNs with high SOC had higher positive affect and lower negative affect than PHNs with low SOC. These results suggest that SOC as a salutogenic model helps PHNs to cope with the family and work juggling as well as the occupational stress. Implications for nursing management on strengthening SOC of PHNs are discussed.

As American health care evolves, an increasing number of doctors are pursuing MBAs. However, relatively little is known about how business training translates into their future careers. This study characterizes ophthalmologists who have completed MBAs and identifies opportunities for physician leadership in the field. Cross-sectional study. We identified 120 ophthalmologists who hold MBAs. We searched each individual's online profiles to collect information on demographics, training, and professional activities. Physician-MBAs in ophthalmology are 80% male; 80% are fellowship trained; and 28% are in primarily nonclinical roles and 55% participate in significant nonclinical activity. Hospital administration is most common (31%), followed by pharmaceutical administration (7%) and consulting (5%). Older ophthalmologist-MBAs were more likely to work in nonclinical roles, with 79% of those who completed residency before 2000 engaged in significant nonclinical activity compared to 30% of those who completed residency after 2000. The most common employers of physician-MBAs in ophthalmology are academic medical centers (43%), large group practices (30%), and private practices (13%). The majority of ophthalmologist-MBAs work in primarily clinical roles, although a sizable proportion hold nonclinical positions. Moving forward, we anticipate an increased role for physician leaders in health care administration, policy, and entrepreneurship. While formal management training is not necessary for these roles, a growing number of physicians have sought out MBAs to support their nonclinical interests. Copyright © 2018 Elsevier Inc.

Teaching is considered a highly stressful occupation, with work-related stress levels among teachers being among the highest compared to other professions. Unfortunately there are very few studies regarding the levels of work-related stress among teachers in the Republic of Macedonia. To identify the level of self-perceived work-related stress among teachers in elementary schools and its relationship to gender, age, position in the workplace, the level of education and working experience. We performed a descriptive-analytical model of a cross-sectional study that involved 300 teachers employed in nine elementary schools. Evaluation of examined subjects included completion of a specially designed questionnaire. We found that the majority of interviewed teachers perceive their work-related stress as moderate. The level of work-related stress was significantly high related to the gender, age, position in workplace, as well as working experience (p < 0.01), while it was significant related to level of education (p < 0.05). Significantly greater number of lower-grade teachers perceives the workplace as extremely stressful as compared to the upper-grade teachers (18.5% vs. 5.45%), while the same is true for female respondents as compared to the male ones (15.38% vs. 3.8%). In addition, our results show that teachers with university education significantly more often associate their workplace with stronger stress than their colleagues with high education (13.48% vs. 9.4%). We also found that there is no significant difference of stress levels between new and more experienced teachers. Our findings confirm that the majority of interviewed teachers perceived their work-related stress as high or very high. In terms of the relationship between the level of teachers' stress and certain demographic and job characteristics, according to our results, the level of work-related stress has shown significantly high relation to gender, age, levels of grades taught as well as working experience, and significant relation to the level of education.

This study adopted a spillover-crossover model to examine the roles of personality and perceived social support as antecedents of the work-family interface among dual-earner couples in China. Married couples (N = 306) from 2 major cities in China (Shanghai and Jinan) completed questionnaires measuring a relationship-oriented personality trait (i.e., family orientation), perceived family and work support, and work-family conflict and enhancement. The results showed that family orientation and perceived family support was positively associated with family-to-work enhancement and negatively associated with family-to-work conflict for both husbands and wives. Perceived work support was positively associated with family-to-work enhancement for wives and negatively associated with work-to-family conflict for husbands. Similarities in family orientation between partners were positively correlated with the individual's family-to-work enhancement. This study also illustrated the crossover of the work-family interface between dual-earner couples by using the actor-partner interdependence model. The pattern of associations between personality trait and perceived social support varied by gender. Husbands' family orientation was negatively correlated with work-to-family enhancement experienced by wives, and husbands' perceived work support was positively correlated with work-to-family enhancement experienced by wives. Wives' perceived work support was positively correlated with family-to-work conflict experienced by husbands.

Dementia training programmes for staff working in long-term care settings have been found to be effective in improving staff outcomes. This study investigated the impact of a dementia training programme for all Maltese nursing staff working in public nursing/residential homes on their knowledge, attitudes and confidence. Additionally, we identified the predictors of these domains before and after the programme. A 14-hour training programme focusing on dementia management, care and policy was developed for all nursing staff working in public nursing and residential homes in Malta. A pretest-posttest design was used to evaluate the participants' knowledge of dementia, attitudes and confidence in working with residents with dementia using validated tools. Demographic variables were measured and compared with each staff domain. The majority of nursing staff attended the training programme with 261 fully completed questionnaires being collected pre-training and 214 post-training. The programme significantly improved nursing staff knowledge, attitudes and confidence. Stepwise regression analysis of each staff domain showed that the strongest predictor in all models at pre-training was the intensity of previous training programmes. Furthermore, staff who attended previous training continued to improve in their attitudes and confidence following programme completion. The study continues to shed further evidence on the impact of dementia training programs on staff outcomes. It also indicated that the intensity of previous participation in dementia training programmes was related to the participants' knowledge, attitudes and confidence and that continual exposure to training had a cumulative effect.

The National Heart, Lung and Blood Institute (NHLBI) Asthma Clinical Research Network (ACRN) recently completed its work after 20 years of collaboration as a multicentre clinical trial network. When formed, its stated mission was to perform multiple controlled clinical trials for treating patients with asthma by dispassionately examining new and existing therapies, and to rapidly communicate its findings to the medical community. The ACRN conducted 15 major clinical trials. In addition, clinical data, manual of operations, protocols and template informed consents from all ACRN trials are available via NHLBI BioLINCC (https://biolincc.nhlbi.nih.gov/studies/). This network contributed major insights into the use of inhaled corticosteroids, short-acting and long-acting ß-adrenergic agonists, leukotriene receptor antagonists, and novel agents (tiotropium, colchicine and macrolide antibiotics). They also pioneered studies of the variability in drug response, predictors of treatment response and pharmacogenetics. This review highlights the major research observations from the ACRN that have impacted the current management of asthma.

US Registered Dietitian Nutritionists' Knowledge and Attitudes of Intuitive Eating and Use of Various Weight Management Practices.

2017-09-01

Researchers have been advocating for a new weight-inclusive paradigm that focuses on health rather than weight. One important component of this model is intuitive eating. Although registered dietitian nutritionists (RDNs) are the nation's food and nutrition experts, RDNs' knowledge of and attitudes toward intuitive eating and use of traditional or restrictive strategies are unknown. The purpose of this study was to characterize RDNs' knowledge of and attitudes toward an intuitive eating lifestyle and describe use of traditional weight management and nonrestrictive lifestyle practices with clients. This was a cross-sectional study. A validated survey was distributed using online survey software to 88,834 RDNs. There were 18,622 respondents who completed the survey (25%). The majority of RDNs were knowledgeable about intuitive eating, answering 71% of items correctly. The majority of RDNs had a positive view on each attitude item. RDNs who work in weight management reported using nonrestrictive/intuitive eating practices more than traditional/restrictive practices. RDNs who were women (P<0.001), had advanced education (P<0.001), worked in a private practice setting (P<0.001), completed at least one certificate of training in weight management (P<0.001), had more experience in weight management counseling (P<0.001), and had greater intuitive eating knowledge (P<0.001) were more likely to report greater use of nonrestrictive/intuitive eating practices. This study provides evidence that RDNs are using an intuitive eating approach more often than traditional weight management practices. Copyright © 2017 Academy of Nutrition and Dietetics.

The leading cause of preventable death, in the most vulnerable segments of society, whom social workers often counsel, is cigarette smoking. The purpose of this study was to assess tobacco smoking cessation training in clinical social work programs. A valid 21-item questionnaire was sent to the entire population of 189 clinical graduate social work programs identified by the Council on Social Work Education. A three-wave mailing process was used to maximize the return rate. Directors from 112 clinical social work programs returned completed questionnaires (61 percent). The majority (91 percent) of directors reported having never thought about offering formal smoking cessation training, and only nine of the programs (8 percent) currently provided formal smoking cessation education. The three leading barriers to offering smoking cessation education were as follows: not a priority (60 percent), not enough time (55 percent), and not required by the accrediting body (41 percent). These findings indicate that clinical social work students are not receiving standardized smoking cessation education to assist in improving the well-being of their clients. The national accrediting body for graduate clinical social work programs should consider implementing guidelines for smoking cessation training in the curriculums.

The purpose of this study was to assess both direct and indirect relationships between professional commitment, job satisfaction, and work stress in public health nurses (PHNs) in Taiwan. The two major questions addressed were as follows: What were the professional commitment, job satisfaction, and work stress among PHNs? What model accurately portrays the relationships between these three independent variables? Exploration of the causal pathways among these variables revealed a fitness model. A structured, self-administered questionnaire with three scales was distributed to the subjects. A total of 258 subjects completed the questionnaire, yielding a 90% response rate. Results demonstrate a significant, direct, and positive effect of professional commitment on job satisfaction, as well as a significant inverse influence of job satisfaction on work stress. An indirect effect of professional commitment on work stress through job satisfaction was also revealed in the findings. All paths in the model were significant (P < .05). The findings of the study can help show that professional commitment plays an antecedent role to job satisfaction and work stress of nurses. This study suggests that professional commitment is an important factor related to work stress and that health care institutions should be concerned with this issue.

Foundation Training is designed for doctors in their first two years of post-graduation. The number of foundation doctors (FD) in the UK working nights has reduced because of a perception that clinical supervision at night is unsatisfactory and that minimal training opportunities exist. We aimed to assess the value of night shifts to FDs and hypothesised that removing FDs from nights may be detrimental to training. Using a survey, we assessed the number of FDs working nights in London, FDs views on working nights and their supervision at night. We evaluated whether working at night, compared to daytime working provided opportunities to achieve foundation competencies. 83% (N = 2157/2593) of FDs completed the survey. Over 90% of FDs who worked nights felt that the experience they gained improved their ability to prioritise, make decisions and plan. FDs who worked nights reported higher scores for achieving competencies in history taking (2.67 vs. 2.51; p = 0.00), examination (2.72 vs. 2.59; p = 0.01) and resuscitation (2.27 vs. 1.96; p = 0.00). The majority (65%) felt adequately supervised. Our survey has demonstrated that FDs find working nights a valuable experience, providing important training opportunities, which are additional to those encountered during daytime working.

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

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

Background The aim of this study was to investigate the burden experienced by nursing personnel working irregular shifts in Greece and to conduct the first test of a Greek version of the Standard Shiftwork Index (SSI). Methods A cross-sectional survey was carried out. The SSI was completed by 365 nurses and nursing assistants working shifts, including nights. Results Female nursing personnel and those suffering from a chronic disease were most affected by working rotating shifts as they had elevated scores on the majority of the SSI scales, such as sleep, chronic fatigue, digestive and cardiovascular problems, general health questionnaire, cognitive and somatic anxiety, shift time satisfaction, engagement and disengagement strategies, languidity, flexibility, and neurotisicm. Nurses with longer working experience and those with family responsibilities also scored higher on some of the SSI scales, such as the sleep, shift time satisfaction, social and domestic disruption, disengagement strategies, morningness, and languidity scales. Conclusion Shiftwork affects female nurses, those with chronic disease, older age, and domestic responsibilities more severely. Therefore management should take these factors into account when designing work schedules to alleviate the burden caused by shiftwork. PMID:25180137

Physiotherapy is the largest healthcare contributor after nursing and medicine and it is important to understand its employment characteristics. This study aimed to explore workforce trends for recent physiotherapy graduates, including satisfaction and motivating factors, and future career intentions. A self-administered questionnaire was provided to contactable entry-level physiotherapy graduates (2000-2004) from Curtin University. Of 256 respondents (62.9%), 76.5% were employed full-time. A total of 45% of physiotherapists worked in the public health system; 79.3% worked in cities; 92.2% were clinicians. Top salaries were earned by those completing more continuing professional development hours, working privately, in rural locations and males. A total of 65% (n = 118) of respondents believed they would leave physiotherapy within 10 years. The best aspects of working in physiotherapy were 'helping people', 'flexibility' and 'working in a healthcare team'. Major areas for improvement were 'remuneration', 'skill recognition' and 'marketing'. This study suggests serious implications for the future of the health; planning to avert shortages is essential.

[Caught between economic pressure and work-life balance--perspectives on emigration of German health professionals to Austria].

Schmidt, A E; Klambauer, E

2014-05-01

Given the increasing lack of medical doctors in Germany, this study aimed to investigate the professional situation and the push and pull factors of German medical specialists working in Austrian hospitals. This explorative study is based on semi-structured interviews with 14 specialists working in Austria, who completed their education partly or fully in Germany. The material has been interpreted using qualitative content analysis. Better work-life balance, higher quality of life and more favourable working conditions represent major reasons for German specialists to stay in Austria. Moreover, the higher density of medical doctors in Austrian hospitals can have an impact on the distribution of responsibilities among health-care personnel, and on hospital performance. In the light of recent reforms in the German health-care system, the study underlines the importance of qualitative factors for the satisfaction of German medical doctors. These factors should be further analysed in order to avoid a brain drain of high-qualified health care staff in the future. © Georg Thieme Verlag KG Stuttgart · New York.

Impact of missing data strategies in studies of parental employment and health: Missing items, missing waves, and missing mothers.

2018-07-01

Understanding the long-term health effects of employment - a major social determinant - on population health is best understood via longitudinal cohort studies, yet missing data (attrition, item non-response) remain a ubiquitous challenge. Additionally, and unique to the work-family context, is the intermittent participation of parents, particularly mothers, in employment, yielding 'incomplete' data. Missing data are patterned by gender and social circumstances, and the extent and nature of resulting biases are unknown. This study investigates how estimates of the association between work-family conflict and mental health depend on the use of four different approaches to missing data treatment, each of which allows for progressive inclusion of more cases in the analyses. We used 5 waves of data from 4983 mothers participating in the Longitudinal Study of Australian Children. Only 23% had completely observed work-family conflict data across all waves. Participants with and without missing data differed such that complete cases were the most advantaged group. Comparison of the missing data treatments indicate the expected narrowing of confidence intervals when more sample were included. However, impact on the estimated strength of association varied by level of exposure: At the lower levels of work-family conflict, estimates strengthened (were larger); at higher levels they weakened (were smaller). Our results suggest that inadequate handling of missing data in extant longitudinal studies of work-family conflict and mental health may have misestimated the adverse effects of work-family conflict, particularly for mothers. Considerable caution should be exercised in interpreting analyses that fail to explore and account for biases arising from missing data. Copyright © 2018. Published by Elsevier Ltd.

We investigated the association between the content of the information exchanged between clients and therapists during mental health intake and the quality of the therapeutic alliance. Thirty-eight therapists and 107 clients from four mental health clinics in Israel participated in the study. The content of information discussed was coded directly from the recorded intakes by blinded raters. Clients and therapists completed the Working Alliance Inventory immediately following the intake. Therapists spent the majority of intake time in collecting information about their clients' diagnostic symptoms and personal history and sociocultural background. Due to the high negative correlation between these factors, r(107) = -.68, p < .001, we created a measure of delta score with higher scores reflecting more discussion of personal history and sociocultural background and less discussion of diagnostic symptoms. We computed three-level hierarchical linear model analysis, with intakes nested within therapists and therapists nested within sites, to examine the association between the delta score and the working alliance, while controlling for intake duration. Results showed significant association between the delta score and clients' rating of the working alliance (γ200 = 0.014, p = .02), indicating that discussing more personal history and sociocultural background and less diagnostic symptoms was associated with better clients' rating of the working alliance. Therapists' rating of the working alliance was not significantly associated with the content of the information exchanged. The restricted intake time allocated to therapists dictates use of strategies to deal with time trade-offs to complete a thorough diagnostic assessment while allowing clients to tell their personal story.

The Relationship between Symptom Relief and Psychosocial Functional Improvement during Acute Electroconvulsive Therapy for Patients with Major Depressive Disorder.

PubMed

Lin, Ching-Hua; Yang, Wei-Cheng

2017-07-01

We aimed to compare the degree of symptom relief to psychosocial functional (abbreviated as "functional") improvement and explore the relationships between symptom relief and functional improvement during acute electroconvulsive therapy for patients with major depressive disorder. Major depressive disorder inpatients (n=130) requiring electroconvulsive therapy were recruited. Electroconvulsive therapy was generally performed for a maximum of 12 treatments. Symptom severity, using the 17-item Hamilton Depression Rating Scale, and psychosocial functioning (abbreviated as "functioning"), using the Modified Work and Social Adjustment Scale, were assessed before electroconvulsive therapy, after every 3 electroconvulsive therapy treatments, and after the final electroconvulsive therapy. Both 17-item Hamilton Depression Rating Scale and Modified Work and Social Adjustment Scale scores were converted to T-score units to compare the degrees of changes between depressive symptoms and functioning after electroconvulsive therapy. Structural equation modeling was used to test the relationships between 17-item Hamilton Depression Rating Scale and Modified Work and Social Adjustment Scale during acute electroconvulsive therapy. One hundred sixteen patients who completed at least the first 3 electroconvulsive therapy treatments entered the analysis. Reduction of 17-item Hamilton Depression Rating Scale T-scores was significantly greater than that of Modified Work and Social Adjustment Scale T-scores at assessments 2, 3, 4, and 5. The model analyzed by structural equation modeling satisfied all indices of goodness-of-fit (chi-square = 32.882, P =.107, TLI = 0.92, CFI = 0.984, RMSEA = 0.057). The 17-item Hamilton Depression Rating Scale change did not predict subsequent Modified Work and Social Adjustment Scale change. Functioning improved less than depressive symptoms during acute electroconvulsive therapy. Symptom reduction did not predict subsequent functional improvement. Depressive symptoms and functional impairment are distinct domains and should be assessed independently to accurately reflect the effectiveness of electroconvulsive therapy. © The Author 2017.

NASA is embarked on a new era of space exploration that will lead to new capabilities, new destinations, and new discoveries by both human and robotic explorers. Today, the International Space Station (ISS), supported by NASA's commercial partners, and robotic probes, are yielding knowledge that will help make this exploration possible. NASA is developing both the Orion crew vehicle and the Space Launch System (SLS) that will carry out a series of increasingly challenging missions that will eventually lead to human exploration of Mars. This paper will discuss the development and progress on the SLS. The SLS architecture was designed to be safe, affordable, and sustainable. The current configuration is the result of literally thousands of trade studies involving cost, performance, mission requirements, and other metrics. The initial configuration of SLS, designated Block 1, will launch a minimum of 70 metric tons (t) into low Earth orbit - significantly greater capability than any current launch vehicle. It is designed to evolve to a capability of 130 t through the use of upgraded main engines, advanced boosters, and a new upper stage. With more payload mass and volume capability than any rocket in history, SLS offers mission planners larger payloads, faster trip times, simpler design, shorter design cycles, and greater opportunity for mission success. Since the program was officially created in fall 2011, it has made significant progress toward first launch readiness of the Block 1 vehicle in 2018. Every major element of SLS continued to make significant progress in 2015. The Boosters element fired Qualification Motor 1 (QM-1) in March 2015, to test the 5-segment motor, including new insulation, joint, and propellant grain designs. The Stages element marked the completion of more than 70 major components of test article and flight core stage tanks. The Liquid Engines element conducted seven test firings of an RS-25 engine under SLS conditions. The Spacecraft/Payload Integration and Evolution element marked completion of the upper stage test article. Major work continues in 2016 as the program continues both flight and development RS-25 engine testing, begins welding test article and flight core stage tanks, completes stage adapter manufacturing, and test fires the second booster qualification motor. This paper will discuss the program's key accomplishments to date and the challenging work ahead for what will be the world's most capable launch vehicle.

China is realizing increases in women engaged in premarital sex and multiple sex partner behavior. Our aim was to examine prevalence and determinants of multiple sex partner behavior among female undergraduates in China. Anonymously completed questionnaires were received from 4,769 unmarried female undergraduates, recruited using randomized cluster sampling by type of university and students' major and grade. Items captured demographic, family, peer and work influence, and student factors (major, academic performance, and sex-related knowledge and attitudes). To examine risk factors for sexual behaviors, we used multi-level logistic regression, yielding odds ratios (OR) and 95% confidence intervals (95% CI). Of 4,769 female students, 863 (18.10%) reported ever having sexual intercourse, and 5.31% reported having multiple sex partners (29.32% of all women having sexual intercourse). Several demographic, family, peer and work influences, and student factors (including major, performance, knowledge, and attitude toward sex) were risk factors for ever having sex. However, risk factors for multiple sex partners only included working in a place of entertainment, having current close friends that were living with boyfriends, poor academic performance, and positive attitudes toward multiple partners. These women also were more likely to practice masturbation, start having sex at a younger age, have sex with married men and/or men not their "boyfriends" at first coitus, and not use condoms consistently. A small but important subset of Chinese female undergraduates is engaged in unprotected sex with multiple sex partners. Interventions need to target at risk women, stressing the importance of consistent condom use.

Physics as a discipline is not alone in having difficulty finding qualified teachers. Under-qualified teachers are present in high school Mathematics, Chemistry, Biology, and Earth-science classrooms as well. Columbus State University (CSU) has formed the Mathematics and Science Secondary Teachers (MaSST) Preparation Council to recruit more majors into our existing secondary teaching programs: Mathematics, Biology, Chemistry, and Geology. College of Education and College of Science faculty are working together to create a higher profile for these majors at our institution within the state of Georgia. In addition, we are planning an aggressive campaign to recruit from within by implementing a peer-tutoring program using outstanding students who have completed introductory math and science courses. Our group’s organization and initiatives can serve as a model for other institutions concerned about recruiting more high-school teachers.

To investigate the outcome of subjects with major depressive disorder after serious suicide attempt and to examine the effect of psychotic symptoms on their outcome. The study population included all individuals aged 16 years or older in Finland who were hospitalized with ICD-10 diagnoses of major depressive disorder and attempted suicide from 1996 to 2003 (N = 1,820). The main outcome measures were completed suicides, overall mortality, and repeated suicide attempts during drug treatment versus no treatment. During the 4-year follow-up period, 13% of patients died, 6% completed suicide, and 31% made a repeat suicide attempt. Subjects with major depression with psychotic features completed suicide more often than subjects without psychotic features during the follow-up (hazard ratio [HR] 3.32; 95% CI, 1.95 - 5.67). Antidepressant treatment reduced all-cause mortality by 24% (HR 0.74; 95% CI, 0.56 - 0.97) but did not reduce suicide mortality (HR 1.06; 95% CI, 0.71 - 1.58). Psychotic symptoms during major depressive episode increase the risk of completed suicide after serious suicide attempt. The quality of treatment for major depression with psychotic features after attempted suicide should be improved to prevent suicide. Copyright 2009 Physicians Postgraduate Press, Inc.

Data obtained primarily from the Student Information System of the University of Missouri were used to determine the graduation rate of freshmen and transfer students who initially enrolled as animal science majors during the fall semester of a consecutive 4-yr period. The primary objective of this study was to determine the percentage of students who completed a bachelor of science (BS) degree in animal science. This study also investigated the predictability of graduation rate and academic performance [cumulative grade point average (GPA)] and attempted to ascertain why students changed their major or failed to complete a baccalaureate degree. Independent variables included in the analysis of data included sex, composite ACT score, high school class rank, advising group, high school graduation class size, predicted GPA, first-semester GPA, cumulative GPA, and the background of the student (farm/ranch, rural non-farm/ranch, or urban). The total number of students in the data set was 457, representing 378 who enrolled as first-semester freshmen and 79 transfer students. The data were statistically analyzed using various procedures of SAS. A questionnaire was sent to 256 former students who either did not complete a degree at the University of Missouri (n = 126) or completed a baccalaureate degree in a major other than animal science (n = 130) to determine their reason(s) for changing major or leaving the University of Missouri. Thirty-five percent of the students completed a BS degree in animal science. Approximately 14% completed a degree in some other major in the College of Agriculture, Food and Natural Resources and 15% completed a baccalaureate degree in some major outside of the College of Agriculture, Food and Natural Resources at the university. Another 3.9% completed a degree in veterinary medicine. Graduation rate was 67.6%, which was similar to the campus average. The use of 5 independent variables resulted in 64% accuracy at predicting graduation rate. The best predictor of cumulative GPA was the first-semester GPA of the student (R(2) = 0.67). Poor academic performance was the primary reason students did not complete a BS degree; however, students suggested poor advising was a contributing factor.

1995-10-01

This study was conducted to describe women's perceptions of their maternity leave policy and its implementation, maternity leave benefits, postpartum work experience, and factors that relate to returning to work. Surveys were mailed to 436 married, recently employed, first-time mothers at 1, 3, 6, 9 and 12 months postpartum. Most respondents said they had written maternity leave policies they could understand, but they were not completely satisfied with their policies. The average 11.1-week maternity leave was considerably shorter than their 8-month ideal, and only 25.5% had the option of working part-time. A minority (35.8%) were allowed to use personal days to care for a sick infant. Most women were distressed about making child care arrangements. Compared with women who remained at home, those who returned to work complained of more respiratory, gynecologic, and breast symptoms. Relatively little is known about women's postpartum work experience. In this study, return to work after delivery was related to several demographic, occupational, and social factors and was associated with health problems and concerns about child care. With a majority of new mothers now returning to work, attention has recently been directed to factors that facilitate the merger of work and parenting roles. One such important factor is women's parental or maternity leave benefits, the focus of this study.

Work-Based Curriculum to Broaden Learners' Participation in Science: Insights for Designers

Around the globe, science education during compulsory schooling is envisioned for all learners regardless of their educational and career aspirations, including learners bound to the workforce upon secondary school completion. Yet, a major barrier in attaining this vision is low learner participation in secondary school science. Because curricula play a major role in shaping enacted learning, this study investigated how designers developed a high school physics curriculum with positive learning outcomes in learners with varied inclinations. Qualitative analysis of documents and semistructured interviews with the designers focused on the curriculum in different stages—from designers' ideas about learning goals to their vision for enactment to the printed materials—and on the design processes that brought them to fruition. This revealed designers' emphases on fostering workplace connections via learning goals and activities, and printed supports. The curriculum supported workplace-inspired, hands-on design-and-build projects, developed to address deeply a limited set of standards aligned learning goals. The curriculum also supported learners' interactions with relevant workplace professionals. To create these features, the designers reviewed other curricula to develop vision and printed supports, tested activities internally to assess content coverage, surveyed states in the USA receiving federal school-to-work grants and reviewed occupational information to choose unit topics and career contexts, and visited actual workplaces to learn about authentic praxis. Based on the worked example, this paper offers guidelines for designing work-based science curriculum products and processes that can serve the work of other designers, as well as recommendations for research serving designers and policymakers.

We have made significant landmarks in our proposed work in the last 4 years (3 years plus 1 year of no cost extension). We have developed the simulation capability of the major isotopes in CESM. In particular, we have completed the implementation of the stable water isotopes (δ 18O, δD) into the components for the atmosphere, ocean, land surface, runoff transport, sea ice, and coupler. In addition, the carbon isotopes (abiotic and biotic radiocarbon, δ 13 C) have been implemented into the CESM ocean and land models, and long spinup simulations have been completed (Jahn et al., 2015). Furthermore, wemore » have added abiotic Neodymium to the CESM ocean model as a tracer of ocean circulation, also measured by the proxy data community. Fullycoupled simulations with the stable water isotopes and ocean radiocarbon are currently being run for the preindustrial and also the Last Glacial Maximum. We have secured 19 million core-hours on the NWSC Yellowstone supercomputer for 12 months. Together with some CESM Paleoclimate Working Group CSL Yellowstone core hours, we are guaranteed sufficient computing for the spin-up experiments and deglaciation simulations for 21 to 15ka.« less

The U.S. Department of Energy (DOE) and Fluor Fernald have completed the majority of the cleanup of the Fernald Site. The over 1,000 acre complex for processing uranium has been demolished and soil contamination has been remediated. With acres of wetlands and prairies replacing the buildings and waste pits. At the end of the project the focus shifted to developing demonstrating the completion of the project and the contract, as well as ensuring a smooth transition of the facility from the DOE's Environmental Management (EM) Program to the DOE's Legacy Management (LM) Program. Working with the DOE, each portion ofmore » the closure contract was examined for specific closure definition. From this negotiation effort the Comprehensive Exit and Transition Plan (CE/T Plan) was written. The CE/T Plan is intended to assist DOE in the analysis that the site is ready for transfer into long-term stewardship (LTS) (also referred to as legacy management) and that Fluor Fernald, Inc. has satisfactorily completed the closure contract statement of work elements. Following the Lessons Learned from the closure of the Rocky Flats Site, the DOE's Legacy Management Program created a matrix of Transition Elements required to ensure adequate information was in place to allow the new prime contractor to perform the Legacy Management scope of work. The transition plan included over 1,000 elements broken down into functional areas and relied on specific Fernald Responsibility Transition Packages (RTPs) for detailed transition actions. The template for Closure and Transition Planning used at the Fernald Site was developed using the best Lessons Learned from across the DOE Complex. The template could be used for other sites, and lessons learned from this closure and transition will be appropriate for all closure projects. (authors)« less

The virtual continuity in learning programme: results.

PubMed

Wood, Eleanor; Tso, Simon

2012-08-01

The implementation of the European Working Time Directive and specialty-driven care has resulted in the loss of continuity of patient care, and thus a loss of continuity in learning. We proposed a potential solution to this fragmentation of junior doctor workplace learning in the Virtual Continuity in Learning Programme (VCLP). The VCLP enables the doctor to follow the virtual patient journey (of an actual patient who is no longer under their care) using the Virtual Consulting Room (VcR), and to understand the rationale behind clinical decision making prior to completing their case-based discussion (CbD) work-based assessments. Fifty-seven out of 62 (92%) of foundation doctors (Homerton University Hospital, London, UK) consented to participate in the study. Web-tracking software was used. Fifty-three out of 57 (93%) doctors completed an initial questionnaire. Twenty-nine out of 57 (51%) doctors returned a follow-up questionnaire 6 months later. Eleven doctors were interviewed in three focus groups: the VcR user group; the VcR non-user group; and a mixed group. The data was analysed qualitatively. Tracking showed 33.3 per cent (19/57) of doctors used the VcR over a 6-month period. Interestingly doctors used the VcR in a range of situations, not solely as instructed. Results enabled us to understand how doctors learn and their perception of using the VCLP to support their learning and completion of work-based assessments. Foundation doctors use the educational resources available, including the VcR, to help structure their workplace learning. The majority of VcR users found it particularly useful for just-in-time learning. The VCLP offers support to junior doctors learning during their preparation for case-based discussion. © Blackwell Publishing Ltd 2012.

Objective This pilot study aimed to produce and evaluate training resources and training in oral health care, including oral hygiene, for carers in care homes in Surrey and Medway.Methods During two training days, for carers from these homes, short, interactive presentations were given on a range of topics relevant to oral health care and oral hygiene of older people, followed by practical training. Prior to any training all attendees completed a 39 question questionnaire to establish their baseline knowledge of oral health and hygiene. At the end of the training day they completed an evaluation form. Fourteen weeks later, they were visited at their place of work and completed the same questionnaire again. Differences in responses between baseline and after 14 weeks were statistically tested using the chi-squared test.Results Sixty-six carers attended the training sessions and 44 were followed up 14 weeks later. The results showed an improvement in carer knowledge at follow up. The majority of carers (36/44) spoke English as their first language. They had a mean age of 41 years, 37 were female and 7 male. They had worked as carers for a mean of 10.9 years (range 4 months-34 years). Over 90% stated that the training day fully met or exceeded their requirements and expectations.Conclusions The results indicated improvements in carer knowledge. However, the carers were atypical of carers in general, as they were self-selected and well-motivated. Nevertheless the content of the training day and the questionnaire should inform future work in this area.

To describe how public prosecutors self-assess their communication approaches and how listeners react to them; to analyze how this relates to gender, age, and work experience. Descriptive, transversal study. A questionnaire was developed and sent to 126 public prosecutors for completion. Thirty-three completed questionnaires were sent back. The independent variables were gender, age, and number of years of professional experience. The dependent variables were communication self-assessment throughout the years of work, communication parameters used, and listeners' reactions. A descriptive analyzis and Fisher's Exact Test was carried out. the sample contained both male and female participants with a median age of 43 years and an average of 20 years of professional experience. Most of the respondents claimed they had experienced demotivation, insecurity, tension, and difficulty when trying to convince listeners. More women than men reported they felt that their communication had worsened throughout their careers. All the women reported they experienced insecurity when speaking in public. One third of the public prosecutors stated they suffered from disorders on their voice. Those respondents aged over 43, experienced greater proportion on voice change than younger ones. In contrast to their younger colleagues, the majority of public prosecutors with more than 20 years of professional experience revealed that they felt insecure when speaking in public. the public prosecutors identified their strong and weak communication parameters. Gender, age, and work experience affect communicative performance.

Cooperative (man-machine) scene analysis techniques were developed whereby humans can provide a computer with guidance when completely automated processing is infeasible. An interactive approach promises significant near-term payoffs in analyzing various types of high volume satellite imagery, as well as vehicle-based imagery used in robot planetary exploration. This report summarizes the work accomplished over the duration of the project and describes in detail three major accomplishments: (1) the interactive design of texture classifiers; (2) a new approach for integrating the segmentation and interpretation phases of scene analysis; and (3) the application of interactive scene analysis techniques to cartography.

Diamond has recently successfully commissioned a major change in the lattice consisting of the substitution of a standard double-bend achromat (DBA) cell with a modified four-bend achromat (4BA) cell called "double-double bend achromat" (DDBA). This work stems from the original studies initiated in 2012 towards a Diamond upgrade and provides the benefit of an additional straight section in the ring available for insertion devices. This paper reviews the DDBA design and layout, the implications for technical subsystems, the associated engineering challenges and the main results of the commissioning completed in April 2017.

We developed a survey to look at psychiatrists' attitudes toward psychotropic prescribing guidelines, specifically the Texas Medication Algorithm Project (TMAP) algorithms. The 22-page survey was distributed to 24 psychiatrists working in 4 CMHC's; 13 completed the survey. 90% agreed that guidelines should be general and flexible. The majority also agreed that guidelines should define how to measure response to a specific agent; fewer agreed guidelines should specify dosage, side effect management, or augmentation strategies. Psychiatrists were familiar with TMAP; none referred to it in their practice. In spite of this, psychiatrists' medication preferences were similar to those suggested by guidelines.

This monograph describes the global records of marine water bears (Phylum Tardigrada). We provide a comprehensive list of marine tardigrades recorded from around the world, providing an up-to-date taxonomy and a complete bibliography accompanied by geographic co-ordinates, habitat, substrate and biogeographic comments. A link is provided to an on-line interactive map where all occurrences for each species are shown. In total we list 197 taxa and their 2240 records from 39 oceans and seas and 18 Major Fishing Areas (FAO). It is hoped this work will serve as a reference point and background for further zoogeographic and taxonomic studies on marine tardigrades.

This study investigated work engagement as a baseline predictor of onset of major depressive episode (MDE). The study used a prospective cohort design, conforming to the STROBE checklist. Participants were recruited from the employee population of a private think tank company (N = 4,270), and 1,058 (24.8%) of them completed a baseline survey, of whom 929 were included in this study. Work engagement and psychological distress at baseline were assessed as predictor variables. MDE was measured at baseline and at each of the follow-ups as the outcome, using the web-based, self-administered version of the Japanese WHO-CIDI 3.0 depression section based upon DSM-IV-TR/DSM-5 criteria. Cox discrete-time hazards analyses were conducted to estimate hazard ratios (95% confidence intervals CIs). Follow-up rates of participants (N = 929) were 78.4%, 67.2%, and 51.6% at 1-, 2-, and 3-year follow-ups, respectively. The association between work engagement at baseline and the onset of MDE was U-shaped. Compared with a group with low work engagement scores, groups with the middle and high scores showed significantly (HR = 0.19, 95% CI = 0.05 to 0.64; p = 0.007) and marginally significantly (HR = 0.48, 95% CI = 0.20 to 1.15, p = 0.099) lower risks of MDE, respectively, over the follow-ups, after adjusting for covariates. The pattern remained the same after additionally adjusting for psychological distress. The present study first demonstrated work engagement as an important predictor of the onset of MDE diagnosed according to an internationally standard diagnostic criteria of mental disorders.

Emergency nurses working in non-Major Trauma Service (non-MTS) facilities face the challenge of providing immediate care to seriously injured patients, despite infrequent presentations at their workplace. A one-day education programme endorsed by the Australian College of Nursing was developed to provide contemporary trauma education for nurses. The aim of this study was to report participants' perceptions of their experience of this programme. Peer reviewed lesson plans were developed to guide educational activities. Of 32 participants, 24 consented to and completed pre and post-programme surveys. Thematic analysis and descriptive statistics were used to report study findings. Most participants were nurses with greater than two years' experience in Emergency Nursing (92%). Trauma patient transfers each year from a non-MTS to a Major Trauma Service occurred infrequently; eight nurses (33.3%) reported greater than10 trauma transfers per year. Participant expectations of the programme included personal growth, knowledge acquisition, increased confidence and a focus on technical skills. Participants reported the day to be worthwhile and valuable; improved confidence, increased knowledge, and the opportunity to discuss current evidence based practice were highly regarded. Recommendations for future programmes included extending to two days and include burns and more complex pathophysiology. With centralisation of trauma care to major trauma services, frequent and continuing education of nurses is essential. Nurses from non-Major Trauma Service facilities in Victoria found this programme worthwhile as they gained knowledge and skills and increased confidence to care for trauma patients.

Relative shortages of rural doctors persist. In 2008 the University of Auckland medical programme introduced a Year 5 regional and rural immersion programme, Pukawakawa, based in Northland, New Zealand (NZ). This study evaluates the early workforce outcomes of graduates of this programme. During 2013 we surveyed Auckland medical graduates who were in the 2008-2011 Pukawakawa cohorts. Questions were asked regarding recent and current place of work, future intentions for place of work, and career preference with reasons why. Qualitative analysis was undertaken to analyse free text responses about experiences of Pukawakawa on this choice. Of the 72 Pukawakawa participants, 45 completed the survey, for a response rate of 63%. In 2013, 62% were working in rural or regional areas, with 31% in the Northland DHB. The great majority intend to work rurally or regionally, with 35.6% intending to return to Northland DHB. Of the respondents, 68% listed general practice in their top three future career intentions. In the early postgraduate years, medical graduates who participated in Pukawakawa are very likely to be working in rural and regional areas. These graduates also show an intention to work in general practice and rural medicine.

2014-07-01

Aim Our aim was to compare the return-to-work rates between individuals supported by their GP plus workplace health advisers (intervention group) and those supported by their GP alone. Workplace sickness absence places a significant cost burden on individuals and the wider economy. Previous research shows better outcomes for individuals if they are supported while still in employment, or have been on sick leave for four weeks or less. Those helped back to work at an early stage are more likely to remain at work. A non-medicalised case-managed approach appears to have the best outcomes and can prevent or reduce the slide onto out-of-work benefits, but UK literature on its effectiveness is sparse. The design was a feasibility-controlled trial in which participants were sickness absentees, or presentees in employment with work-related health problems. Individuals completed health status measures (SF-36; EQ-5D) and a Job Content Questionnaire at baseline and again at four-month follow-up. Findings In the intervention group, 29/60 participants completed both phases of the trial. GP practices referred two control patients, and, despite various attempts by the research team, GPs failed to engage with the trial. This finding is of concern, although not unique in primary care research. In earlier studies, GPs reported a lack of knowledge and confidence in dealing with workplace health issues. Despite this, we report interesting findings from the case-managed group, the majority of whom returned to work within a month. Age and length of sickness absence at recruitment were better predictors of return-to-work rates than the number of case-managed contacts. The traditional randomised controlled trial approach was unsuitable for this study. GPs showed low interest in workplace sickness absence, despite their pivotal role in the process. This study informed a larger Department for Work and Pensions study of case-managed support.

2001-01-01

Major upgrades were made in 1999 to the 6- by 9-Foot (1.8- by 2.7-m) Icing Research Tunnel (IRT) at the NASA Glenn Research Center. These included replacement of the electronic controls for the variable-speed drive motor, replacement of the heat exchanger, complete replacement and enlargement of the leg of the tunnel containing the new heat-exchanger, the addition of flow-expanding and flow-contracting turning vanes upstream and downstream of the heat exchanger, respectively, and the addition of fan outlet guide vanes (OGV's). This paper describes the rationale behind this latest program of IRT upgrades and the program's requirements and goals. An overview is given of the scope of work undertaken by the design and construction contractors, the scale-model IRT (SMIRT) design verification program, the comprehensive reactivation test program initiated upon completion of construction, and the overall management approach followed.

1993-01-01

This project was completed as part of AE-4871, Advanced Spacecraft Design. The intent of the course is to provide experience in the design of all the major components in a spacecraft system. Team members were given responsibility for the design of one of the six primary subsystems: power, structures, propulsion, attitude control, telemetry, tracking and control (TT&C), and thermal control. In addition, a single member worked on configuration control, launch vehicle integration, and a spacecraft test plan. Given an eleven week time constraint, a preliminary design of each subsystem was completed. Where possible, possible component selections were also made. Assistance for this project came principally from the Naval Research Laboratory's Spacecraft Technology Branch. Specific information on components was solicited from representatives in industry. The design project centers on a general purpose satellite bus that is currently being sought by the Strategic Defense Initiative.

There are no author-identified significant results in this report. The general suitability of ERTS imagery in detecting ground originated air pollution has proved to be excellent. The quality and resolution exceeded expectations and has permitted in some instances location of point sources to within a thousand feet. Suitable techniques have not yet been developed for determining or measuring area and line sources of air pollution. A major problem has been cloud cover that has persisted over the area of primary interest, the Chesapeake Bay. Work has been completed on mounting the shipboard transmissometer which will be used for investigations to relate the chlorophyll and suspended sediment content in the waters of the Lower Chesapeake Bay to ERTS-1 imagery. Water sampling, plankton analysis, and preparations for sea collection of water truth along the eastern continental shelf of the U.S. have been completed for use in comparisons with ERTS-1 data.

Complete Dosage Compensation and Sex-Biased Gene Expression in the Moth Manduca sexta

Sex chromosome dosage compensation balances homogametic sex chromosome expression with autosomal expression in the heterogametic sex, leading to sex chromosome expression parity between the sexes. If compensation is incomplete, this can lead to expression imbalance and sex-biased gene expression. Recent work has uncovered an intriguing and variable pattern of dosage compensation across species that includes a lack of complete dosage compensation in ZW species compared with XY species. This has led to the hypothesis that ZW species do not require complete compensation or that complete compensation would negatively affect their fitness. To date, only one study, a study of the moth Bombyx mori, has discovered evidence for complete dosage compensation in a ZW species. We examined another moth species, Manduca sexta, using high-throughput sequencing to survey gene expression in the head tissue of males and females. We found dosage compensation to be complete in M. sexta with average expression between the Z chromosome in males and females being equal. When genes expressed at very low levels are removed by filtering, we found that average autosome expression was highly similar to average Z expression, suggesting that the majority of genes in M. sexta are completely dosage compensated. Further, this compensation was accompanied by sex-specific gene expression associated with important sexually dimorphic traits. We suggest that complete dosage compensation in ZW species might be more common than previously appreciated and linked to additional selective processes, such as sexual selection. More ZW and lepidopteran species should now be examined in a phylogenetic framework, to understand the evolution of dosage compensation. PMID:24558255

Several lines of evidence implicate abnormal serotonergic function in suicidal behavior and completed suicide, including low serotonin transporter binding in postmortem studies of completed suicide. We have also reported low in vivo serotonin transporter binding in major depressive disorder (MDD) during a major depressive episode using positron emission tomography (PET) with [(11)C]McN5652. We quantified regional brain serotonin transporter binding in vivo in depressed suicide attempters, depressed nonattempters, and healthy controls using PET and a superior radiotracer, [(11)C]DASB. Fifty-one subjects with DSM-IV current MDD, 15 of whom were past suicide attempters, and 32 healthy control subjects underwent PET scanning with [(11)C]DASB to quantify in vivo regional brain serotonin transporter binding. Metabolite-corrected arterial input functions and plasma free-fraction were acquired to improve quantification. Depressed suicide attempters had lower serotonin transporter binding in midbrain compared with depressed nonattempters (p = .031) and control subjects (p = .0093). There was no difference in serotonin transporter binding comparing all depressed subjects with healthy control subjects considering six a priori regions of interest simultaneously (p = .41). Low midbrain serotonin transporter binding appears to be related to the pathophysiology of suicidal behavior rather than of major depressive disorder. This is consistent with postmortem work showing low midbrain serotonin transporter binding capacity in depressed suicides and may partially explain discrepant in vivo findings quantifying serotonin transporter in depression. Future studies should investigate midbrain serotonin transporter binding as a predictor of suicidal behavior in MDD and determine the cause of low binding.

1989-01-01

Lincoln University, under the Lincoln Advanced Science and Engineering Reinforcement (LASER) Program, has identified and successfully recruited over 100 students for majors in technical fields. To date, over 70 percent of these students have completed or will complete technical degrees in engineering, physics, chemistry, and computer science. Of those completing the undergraduate degree, over 40 percent have gone on to graduate and professional schools. This success is attributable to well planned approaches to student recruitment, training, personal motivation, retention, and program staff. Very closely coupled to the above factors is a focus designed to achieve excellence in program services and student performance. Future contributions by the LASER Program to the pool of technical minority graduates will have a significant impact. This is already evident from the success of the students that began the first year of the program. With program plans to refine many of the already successful techniques, follow-on activities are expected to make even greater contributions to the availability of technically trained minorities. For example, undergraduate research exposure, broadened summer, and co-op work experiences will be enhanced.

Optimizing Call Patterns for Landline and Cell Phone Surveys.

Reimer, Becky; Roth, Veronica; Montgomery, Robert

2012-01-01

Cell phone surveys have become increasingly popular and researchers have noted major challenges in conducting cost-effective surveys while achieving high response rates. Previous work has shown that calling strategies that maximize both respondent contact and completed interviews for landline surveys may not be the most cost-effective for cell phone surveys. For example, Montgomery, et al. (2011) found important differences between landline and cell samples for best times to call and declines in contact rates after repeated dialing. Using paradata from the 2010 and 2011 National Flu Surveys (sponsored by the Centers for Disease Control and Prevention), we investigate differences in calling outcomes between landline and cell surveys. Specifically, we predict respondent contact and interview completion using logistic regression models that examine the impact of calling on particular days of the week, certain times of the day, number of previous calls, outcomes of previous calls and length of time between calls. We discuss how these differences can be used to increase the likelihood of contacting cooperative respondents and completing interviews for both sample types.

In the General Electric's Economic simplified boiling water reactor (GE-ESBWR) the passive containment cooling system (PCCS) plays a major role in containment pressure control in case of an loss of coolant accident. The PCCS condenser must be able to remove sufficient energy from the reactor containment to prevent containment from exceeding its design pressure following a design basis accident. There are three PCCS condensation modes depending on the containment pressurization due to coolant discharge; complete condensation, cyclic venting and flow through mode. The present work reviews the models and presents model predictive capability along with comparison with existing data frommore » separate effects test. The condensation models in thermal hydraulics code RELAP5 are also assessed to examine its application to various flow modes of condensation. The default model in the code predicts complete condensation well, and basically is Nusselt solution. The UCB model predicts through flow well. None of condensation model in RELAP5 predict complete condensation, cyclic venting, and through flow condensation consistently. New condensation correlations are given that accurately predict all three modes of PCCS condensation. (authors)« less

The insatisfactory completeness of the variables in the Death Certificate (DC) makes it difficult to obtain specific perinatal mortality indicators. To assess the social representation of physicians about the perinatal DC. Twenty-five physicians were interviewed in 15 hospitals in the city of São Paulo, in 2009. Qualitative analysis was performed with the Collective Subject Discourse technique. The DC is primarily considered according to its legal aspect. Physicians feel responsible for fulfilling the cause of death. The majority of them reported receiving help from other professionals to complete information on maternal characteristics and identification variables. There is lack of information on the mother's pre-natal conditions, which can make it difficult to identify the perinatal cause of death, mainly in the Unified Health System (SUS) hospitals. Some participants received specific DC training only when attending medical schools. The organization of medical work may affect the completion of the DC, especially in hospitals from SUS. Other professionals contributed to this task and their training can improve the quality of information.

Sustained imatinib treatment in chronic myeloid leukemia patients can result in complete molecular response allowing discontinuation without relapse. We set out to evaluate the frequency of complete molecular response in imatinib de novo chronic phase chronic myeloid leukemia patients, to identify base-line and under-treatment predictive factors of complete molecular response in patients achieving complete cytogenetic response, and to assess if complete molecular response is associated with a better outcome. A random selection of patients on front-line imatinib therapy (n=266) were considered for inclusion. Complete molecular response was confirmed and defined as MR 4.5 with undetectable BCR-ABL transcript levels. Median follow up was 4.43 years (range 0.79–10.8 years). Sixty-five patients (24%) achieved complete molecular response within a median time of 32.7 months. Absence of spleen enlargement at diagnosis, achieving complete cytogenetic response before 12 months of therapy, and major molecular response during the year following complete cytogenetic response was predictive of achieving further complete molecular response. Patients who achieved complete molecular response had better event-free and failure-free survivals than those with complete cytogenetic response irrespective of major molecular response status (95.2% vs. 64.7% vs. 27.7%, P=0.00124; 98.4% vs. 82.3% vs. 56%, P=0.0335), respectively. Overall survival was identical in the 3 groups. In addition to complete cytogenetic response and major molecular response, further deeper molecular response is associated with better event-free and failure-free survivals, and complete molecular response confers the best outcome.

Physiotherapists are exposed to diverse occupational demands. Until now, little has been known about the interaction between occupational stress and the job satisfaction of physiotherapists. This paper aims to examine their work-related stress and job satisfaction. It will analyse accidents at work and occupational diseases of physiotherapists along with work-related physical and psychosocial stress and job satisfaction. We analysed routine data of the German Institute for Statutory Accident Insurance and Prevention in the Health and Welfare Services (BGW) on accidents at work and occurring en route to/from work as well as occupational diseases of physiotherapists. Work-related stress and job satisfaction were examined in a cross-sectional survey using a standard questionnaire to be completed by subjects themselves. Between 2007 and 2011, 1,229 cases of occupational disease were reported to the BGW. The majority of reports involved skin diseases (73%). Stumbles and falls were the most frequent causes of accidents at work (42.9%). Eighty-five physiotherapists all over Germany took part in the survey. They experience high quantitative demands at work. The main physical demands consist of a torso posture between 45° and 90° and high hand activity. Of the 85 subjects, 51% suffer from complaints of the musculoskeletal system in the neck and thoracic spine area and 24% have skin diseases. Most physiotherapists (88%) are satisfied with their work overall. This is aided by a high degree of influence on their work and breaks, by practical application of skills and expert knowledge, high regard for their profession, varied work and a good atmosphere at work. Reservations tend to be about statutory regulations and the social benefits provided by the German healthcare system. Overall, despite high demands and stress relating to the adequacy of resources, the majority of physiotherapists surveyed seem to be satisfied with their job. The main focus of action to promote the health of physiotherapists should be on preventing skin disease, problems of the musculoskeletal system and accidents caused by stumbles and falls.

To describe the attitudes of veterinarians to their work, career and profession during the 10 years after graduation. Longitudinal study of students who started their course at The University of Queensland in 1985 and 1986, and who completed questionnaires in their first and fifth year as students, and after one, five and 10 years as veterinarians. Data from 129 (96%) questionnaires completed after 10 years as a veterinarian were coded numerically then analysed, together with data from previous questionnaires, with SAS System 7 for Windows 95. After 10 years, almost all respondents were either very glad they had done the veterinary course (57%) or generally glad, though with some misgivings (37%). Despite this, only 55% would definitely become a veterinarian if they 'had to do it over again'. The responses for about one-third were different from those given five years earlier. The views of many were related to the level of support and encouragement received in their first job after graduation. There were 42% who were working less than half-time as veterinarians, and their main reasons were, in order, raising children, long hours of work, attitudes of bosses and clients, and poor pay. A majority was concerned about the ethics and competence of some colleagues, and almost all believed that consideration of costs must influence the type of treatment animals receive. Most veterinarians were glad to have done the veterinary course, but for about one-quarter their career had not lived up to expectations and almost half would not do it again in another incarnation. Stress, hours of work, difficulties in balancing personal life with career and low income were important concerns for many. Low income may contribute to the low number of males entering the veterinary profession.

This paper reports recently completed structural dynamics experimental activities with new ultralightweight and inflatable space structures (a.k.a., "Gossamer" spacecraft) at NASA Langley Research Center, NASA Marshall Space Flight Center, and NASA Goddard Space Flight Center. Nine aspects of this work are covered, as follows: 1) inflated, rigidized tubes, 2) active control experiments, 3) photogrammetry, 4) laser vibrometry, 5) modal tests of inflatable structures, 6) in-vacuum modal tests, 7) tensioned membranes, 8) deployment tests, and 9) flight experiment support. Structural dynamics will play a major role in the design and eventual in-space deployment and performance of Gossamer spacecraft, and experimental R&D work such as this is required now to validate new analytical prediction methods. The activities discussed in the paper are pathfinder accomplishments, conducted on unique components and prototypes of future spacecraft systems.

Acoustic propagation in a thermally stratified atmosphere

NASA Technical Reports Server (NTRS)

Vanmoorhem, W. K.

1985-01-01

This report describes the activities during the fifth six month period of the investigation of acoustic propagation in the atmosphere with a realistic temperature profile. Progress has been achieved in two major directions: comparisons between the lapse model and experimental data taken by NASA during the second tower experiment, and development of a model propagation in an inversion. Data from the second tower experiment became available near the end of 1984 and some comparisons have been carried out, but this work is not complete. Problems with the temperature profiler during the experiment have produced temperature profiles that are difficult to fit the assumed variation of temperature with height, but in cases where reasonable fits have been obtained agreement between the model and the experiments are close. The major weaknesses in the model appear to be the presence of discontinuities in some regions, the low sound levels predicted near the source height, and difficulties with the argument of the Hankel function being outside the allowable range. Work on the inversion model has progressed slowly, and the rays for that case are discussed along with a simple energy conservation model of sound level enhancement in the inversion case.

The purpose of this article is to describe a pilot mentoring program for Early Career Psychologists (ECPs) working in Academic Health Centers (AHCs) and synthesize the lessons learned to contribute to future ECP and AHC career development training programs. The authors describe an early career development model, named the Early Career Boot Camp. This intensive experience was conducted as a workshop meant to build a supportive network and to provide mentorship and survival tools for working in AHCs. Four major components were addressed: professional effectiveness, clinical supervision, strategic career planning, and academic research. Nineteen attendees who were currently less than 5 years post completion of doctoral graduate programs in psychology participated in the program. The majority of boot camp components were rated as good to excellent, with no component receiving below average ratings. Of the components offered within the boot camp, mentoring and research activities were rated the strongest, followed by educational activities, challenges in AHCS, and promotion and tenure. The article describes the purpose, development, implementation, and assessment of the program in detail in an effort to provide an established outline for future organizations to utilize when mentoring ECPs.

Leishmaniasis, a multi-faceted ethereal disease is considered to be one of the World's major communicable diseases that demands exhaustive research and control measures. The substantial data on these protozoan parasites has not been utilized completely to develop potential therapeutic strategies against Leishmaniasis. Dihydrofolate reductase thymidylate synthase (DHFR-TS) plays a major role in the infective state of the parasite and hence the DHFR-TS based drugs remains of much interest to researchers working on Leishmaniasis. Although, crystal structures of DHFR-TS from different species including Plasmodium falciparum and Trypanosoma cruzi are available, the experimentally determined structure of the Leishmania major DHFR-TS has not yet been reported in the Protein Data Bank. A high quality three dimensional structure of L.major DHFR-TS has been modeled through the homology modeling approach. Carefully refined and the energy minimized structure of the modeled protein was validated using a number of structure validation programs to confirm its structure quality. The modeled protein structure was used in the process of structure based virtual screening to figure out a potential lead structure against DHFR TS. The lead molecule identified has a binding affinity of 0.51 nM and clearly follows drug like properties.

Objectives To survey internal medicine physicians and residents who have completed residency in three different eras of medical training regarding their experiences during their intern year and their perceptions of duty-hour reform. Methods An online survey was administered to 268 residents, fellows, and staff physicians who had completed or were completing residency during one of three eras of training: before the 80-hour work week, after the 80-hour work week (instituted in 2003), and after the 16-hour limit on continuous shifts for interns (instituted in 2011). The survey assessed experiences during their intern year of residency and perceptions regarding resident duty-hour reform. Results The majority of respondents (n = 32; 54%) indicated that duty-hour restrictions would result in residents being less prepared for their future careers. In addition, 36% (n = 21) of respondents anticipated a decrease in the quality of patient care under the restricted duty hours. A total of 41% (n = 24) were undecided regarding the impact of duty-hour reform on patient care. Respondents reported time spent on independent study, research, and conference attendance did not increase following the institution of duty-hour restrictions. Conclusions Survey responses indicated that after 18 months of experience with the Accreditation Council for Graduate Medical Education duty-hour restrictions, physician opinions were mixed and a substantial number remain undecided regarding the impact of duty-hour restrictions on resident career preparedness and the quality of patient care.

The Spaceport Command and Control System Project is creating a Checkout and Control System that will eventually launch the next generation of vehicles from Kennedy Space Center. KSC has a large set of Development and Operational equipment already deployed in several facilities, including the Launch Control Center, which requires support. The position of System Administrator will complete tasks across multiple platforms (Linux/Windows), many of them virtual. The Hardware Branch of the Control and Data Systems Division at the Kennedy Space Center uses system administrators for a variety of tasks. The position of system administrator comes with many responsibilities which include maintaining computer systems, repair or set up hardware, install software, create backups and recover drive images are a sample of jobs which one must complete. Other duties may include working with clients in person or over the phone and resolving their computer system needs. Training is a major part of learning how an organization functions and operates. Taking that into consideration, NASA is no exception. Training on how to better protect the NASA computer infrastructure will be a topic to learn, followed by NASA work polices. Attending meetings and discussing progress will be expected. A system administrator will have an account with root access. Root access gives a user full access to a computer system and or network. System admins can remove critical system files and recover files using a tape backup. Problem solving will be an important skill to develop in order to complete the many tasks.

This is the concluding Progress Report for Project 1.1 of the U.S./Russia Joint Coordinating Committee on Radiation Effects Research (JCCRER). An overwhelming majority of our work this period has been to complete our primary obligation of providing a new version of the Techa River Dosimetry System (TRDS), which we call TRDS-2009D; the D denotes deterministic. This system provides estimates of individual doses to members of the Extended Techa River Cohort (ETRC) and post-natal doses to members of the Techa River Offspring Cohort (TROC). The latter doses were calculated with use of the TRDS-2009D. The doses for the members of themore » ETRC have been made available to the American and Russian epidemiologists in September for their studies in deriving radiogenic risk factors. Doses for members of the TROC are being provided to European and Russian epidemiologists, as partial input for studies of risk in this population. Two of our original goals for the completion of this nine-year phase of Project 1.1 were not completed. These are completion of TRDS-2009MC, which was to be a Monte Carlo version of TRDS-2009 that could be used for more explicit analysis of the impact of uncertainty in doses on uncertainty in radiogenic risk factors. The second incomplete goal was to be the provision of household specific external doses (rather than village average). This task was far along, but had to be delayed due to the lead investigator’s work on consideration of a revised source term.« less

A quantitative analysis of factors that influence and predict students' intention to major in and complete an undergraduate program in STEM or non-STEM

The goal of this study was to explore and understand the factors that influence students' intention to major in and complete an undergraduate program in a science, technology, engineering, or mathematics (STEM) discipline, in a non-STEM field, and how students' gender directly and indirectly affects their success in college. A quantitative study of three thousand four (3004) ACT-tested students who entered a Midwestern, land-grant university as freshmen in fall, 1999 was conducted based on their ACT Assessment information and their enrollment and graduation status after five years. A wide variety of variables were considered and logistic regression, factor analysis, and path analysis were used to analyze the data. The results show that students who intended to major in or completed STEM programs generally have better academic qualifications than their counterparts who intended to major in non-STEM fields. Students who intended to major in or completed STEM programs came from lower income families and smaller communities than those who intended to major in or graduated from non-STEM programs. In this study, gender's direct effect on students' college achievement is eleven times the total of gender's indirect effects through several major factors for students in both STEM fields and non-STEM fields. Perhaps nature has favored females when students' achievement is measured as their college GPA. The results also show that the overall high dropout rate is strongly associated with students' inadequate preparation in high school and family income. Out-of-school accomplishment in community service is a negative influence on their completion of a college degree. ACT scores are not necessary for prediction of college graduation.

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

1) To assess work-related quality of life (WRQOL) among medical residents at a university hospital in northeast Thailand. 2) To determine the strength of the association between personal and working condition components and WRQOL among medical residents. A descriptive study was used to describe the WRQOL among medical residents. The study population comprised of all 375 residents affiliated with the university hospital. The Thai version of a self-administered work-related quality of life scale-2 was used for data collection. Testing the reliability revealed a Cronbach's alpha of 0.908. Questionnaires were completed by 259 of 375 (68.3%). The study found that the mean rating by residents for overall WRQOL was 113.8 out of 170 (SD 14.8). Most rated WRQOL as moderate (76.6%). The seven sub-factors were rated as moderate to high for employee engagement and control at work, moderate for home/work interface, general well-being and working conditions, high-moderate for job career satisfaction, and low-moderate for stress at work. Relationships between the personal and working condition components and WRQOL were analyzed using binary logistic regression. Residents in minor specialties had a higher WRQOL than those in major specialties (OR 2.522, 95% CI: 1.37, 4.63). Residents who had less than eight duty shifts/week had a higher WRQOL than those with more than eight duty shifts/week (OR 2.263, 95% CI: 1.16, 4.41). Similarly, residents working with less than 80 hours/week had a higher WRQOL than those working more than 80 hours/week (OR 2.344, 95% CI: 1.17, 4.72). A subgroup analyzes of those working in minor specialties showed the trend that working less than eight shifts/month and working less than 80 hours/week had the potential association with good quality of work-life (QWL). This phenomenon is presented in the subgroup analyses of those working in major specialties. Therefore, working hours and number of shifts might have played important role in contributing good QWL. To increase QWL, the residents and institutions should be better managed to have the appropriate number of working hours and to increase work-life balance, working condition, general well-being, and job-career satisfaction. On the other hand, stress at work must be reduced.

Physics in Colombia started to develop in the 70's as a research part of basic sciences with the acquisition, at that time, of large research equipments such as x-rays and EPR. Experimental work was soon supplemented by theoretical investigations, which led to the formation of research groups in condensed matter. In the early 80's existed such groups in five universities. In this report we present, after a short history of the main steps that guided the initial research subjects, the major areas already developed and the minor research groups that are in the stage of consolidation. Currently this type of work is done at least in 20 universities. We also show the actual numbers of researchers, publications, PhD students and laboratories discriminated in gender to complete an overview of Condensed Matter Physics in Colombia. Finally, we present a short review of the main theoretical issues that have been worked in the last decade focusing on low dimensional systems, their structural and optical properties

Nearby stars of the Galactic disc and halo - IV

The Milky Way Galaxy has an age of about 13 billion years. Solar-type stars evolve all the long way to the realm of degenerate objects on essentially this time-scale. This, as well as the particular advantage that the Sun offers through reliable differential spectroscopic analyses, render these stars the ideal tracers for the fossil record of our parent spiral. Astrophysics is a science that is known to be notoriously plagued by selection effects. The present work - with a major focus in this fourth contribution on model atmosphere analyses of spectroscopic binaries and multiple star systems - aims at a volume-complete sample of about 300 nearby F-, G-, and K-type stars that particularly avoids any kinematical or chemical pre-selection from the outset. It thereby provides an unbiased record of the local stellar populations - the ancient thick disc and the much younger thin disc. On this base, the detailed individual scrutiny of the long-lived stars of both populations unveils the thick disc as a single-burst component with a local normalization of no less than 20 per cent. This enormous fraction, combined with its much larger scaleheight, implies a mass for the thick disc that is comparable to that of the thin disc. On account of its completely different mass-to-light ratio the thick disc thereby becomes the dark side of the Milky Way, an ideal major source for baryonic dark matter. This massive, ancient population consequently challenges any gradual build-up scenario for our parent spiral. Even more, on the supposition that the Galaxy is not unusual, the thick disc - as it emerges from this unbiased spectroscopic work - particularly challenges the hierarchical cold-dark-matter-dominated formation picture for spiral galaxies in general.

The three-year project GPS-TTBP resulted in over 152 publications and 135 presentations. This summary focuses on the scientific progress made by the project team. A major focus of the project was on the physics intrinsic rotation in tokamaks. Progress included the first ever flux driven study of net intrinsic spin-up, mediated by boundary effects (in collaboration with CPES), detailed studies of the microphysics origins of the Rice scaling, comparative studies of symmetry breaking mechanisms, a pioneering study of intrinsic torque driven by trapped electron modes, and studies of intrinsic rotation generation as a thermodynamic engine. Validation studies were performed withmore » C-Mod, DIII-D and CSDX. This work resulted in very successful completion of the FY2010 Theory Milestone Activity for OFES, and several prominent papers of the 2008 and 2010 IAEA Conferences. A second major focus was on the relation between zonal flow formation and transport non-locality. This culminated in the discovery of the ExB staircase - a conceptually new phenomenon. This also makes useful interdisciplinary contact with the physics of the PV staircase, well-known in oceans and atmospheres. A third topic where progress was made was in the simulation and theory of turbulence spreading. This work, now well cited, is important for understanding the dynamics of non-locality in turbulent transport. Progress was made in studies of conjectured non-diffusive transport in trapped electron turbulence. Pioneering studies of ITB formation, coupling to intrinsic rotation and hysteresis were completed. These results may be especially significant for future ITER operation. All told, the physics per dollar performance of this project was quite good. The intense focus was beneficial and SciDAC resources were essential to its success.« less

African horse sickness virus (AHSV) is an arthropod-borne pathogen that infects all species of equidae and causes high mortality in horses. Previously, a recombinant modified vaccinia Ankara (MVA) virus expressing the protein VP2 of AHSV serotype 4 was shown to induce virus neutralising antibodies in horses and protected interferon alpha receptor gene knock-out mice (IFNAR -/-) against virulent AHSV challenge. This study builds on the previous work, examining the protective efficacy of MVA-VP2 vaccination in the natural host of AHSV infection. A study group of 4 horses was vaccinated twice with a recombinant MVA virus expressing the major capsid protein (VP2) of AHSV serotype 9. Vaccinated animals and a control group of unvaccinated horses were then challenged with a virulent strain of AHSV-9. The vaccinated animals were completely protected against clinical disease and also against viraemia as measured by standard end-point dilution assays. In contrast, all control horses presented viraemia after challenge and succumbed to the infection. These results demonstrate the potential of recombinant MVA viruses expressing the outer capsid VP2 of AHSV as a protective vaccine against AHSV infection in the field. Copyright © 2014 The Authors.

Entanglement has been studied extensively for understanding the mysteries of non-classical correlations between quantum systems. In the bipartite case, there are well known monotones for quantifying entanglement such as concurrence, relative entropy of entanglement (REE) and negativity, which cannot be increased via local operations. The study on these monotones has been a hot topic in quantum information [1-7] in order to understand the role of entanglement in this discipline. It can be observed that from any arbitrary quantum pure state a mixed state can obtained. A natural generalization of this observation would be to consider local operations classical communication (LOCC)more » transformations between general pure states of two parties. Although this question is a little more difficult, a complete solution has been developed using the mathematical framework of the majorization theory [8]. In this work, we analyze the relation between entanglement monotones concurrence and negativity with respect to majorization for general two-level quantum systems of two particles.« less

The recently completed study for the Advanced Technology Large-Aperture Telescope (ATLAST) was the culmination of three years of work that built upon earlier engineering designs, science objectives, and sustained recommendations for technology investments. Since the mid-1980s, multiple teams of astronomers, technologists, and engineers have developed concepts for a large-aperture UV/optical/IR space observatory to follow the Hubble Space Telescope (HST). Especially over the past decade, technology advances and exciting scientific results has led to growing support for development in the 2020s of a large UVOIR space observatory. Here we summarize the history of major mission designs, scientific goals, key technology recommendations, community workshops and conferences, and recommendations to NASA for a major UV/optical/IR observatory to follow HST. We conclude with a capsule summary of the ATLAST reference design developed over the past three years.

Geochemical and analytical implications of extensive sulfur retention in ash from Indonesian peats

1993-01-01

Sulfur is an analyte of considerable importance to the complete major element analysis of ash from low-sulfur, low-ash Indonesian peats. Most analytical schemes for major element peat- and coal-ash analyses, including the inductively coupled plasma atomic emission spectrometry method used in this work, do not permit measurement of sulfur in the ash. As a result, oxide totals cannot be used as a check on accuracy of analysis. Alternative quality control checks verify the accuracy of the cation analyses. Cation and sulfur correlations with percent ash yield suggest that silicon and titanium, and to a lesser extent, aluminum, generally originate as minerals, whereas magnesium and sulfur generally originate from organic matter. Cation correlations with oxide totals indicate that, for these Indonesian peats, magnesium dominates sulfur fixation during ashing because it is considerably more abundant in the ash than calcium, the next most important cation in sulfur fixation.

Work-related musculoskeletal disorders (MSDs) of the upper extremities are a major problem globally, though most relevant studies have been reported from high income countries. The prevalence of neck and shoulder pain and its association with work-related physical and psychosocial factors and life style was determined by a cross-sectional survey using the Nordic Musculoskeletal Questionnaire (NMQ) in the largest Iranian car manufacturing company, with more than 18,000 employees. A total of 14,384 (79.8%) of all employees completed the questionnaire. Depending on the questions used to measure neck and shoulder symptoms, the prevalence varied widely (from 20.5% to 3.9%). In the multiple logistic regression model, limited to employees with at least 1 year of work experience, risk indicators for disabling pain of the neck and/or shoulder that remained for male were: duration of employment, high visual demands, repetitive work, sitting position at work, awkward working position, no regular exercise, monotonous work, lack of encouraging organizational culture, and anxiety concerning change. For female repetitive work, sitting position at work and no support if there is trouble at work were the only remaining factors. The study confirms the effects of physical and psychosocial factors on neck and shoulder symptoms among automobile manufacturing workers in a low to middle income country in spite of the relative youth and job insecurity of the population.

Besides an improvement in quality of life, one of the major targets of rehabilitation programmes is to preserve the ability to work and to integrate the patient into working life again. Cancer in particular is often associated with a loss of employment and joblessness, frequently caused by incomplete rehabilitation. The programme is aimed at young cancer patients aged between 18 and 40 years. In addition to medical rehabilitation, they undergo a specially developed programme which they complete in groups of no more than 5 persons. At baseline and at the end of the 3 weeks rehabilitation, tests on physical and mental capacity are conducted. During rehabilitation, different training programmes concerning mobility at work, fine motor skills and cognitive abilities are held, complemented by an intensive psycho-social training programme. Additionally, patients receive individual social counselling. So far, 34 patients with an average age of 31.8 years have participated in the programme, 65% of them suffering from malignant haematological diseases. The combination of a medical and a vocational rehabilitation programme was judged extremely positively by the participants, which remained the case 6 months after completion of the programme. The rehabilitation programme significantly reduced work incapacity periods: at baseline, only 6% of the participants had not experienced such periods, but after 3 and 6 months, this rate had increased to 61% and 62% respectively. This was accompanied by an increased health-related quality of life and reduced fatigue. With our pilot project we were able to show that such a programme is feasible, can be well integrated into clinical routine and is successful.

Studies based on dentists' clinical practice possess vital relevance to understand factors leading the clinicians to choose by a specific technique over another. This study investigated which clinical conduct therapies are adopted by dentists in front of deep caries. Was evaluated how the place of work, post-graduate training and years since complete graduation influenced their decisions. A cross-sectional study was performed using a self-applied questionnaire with dentists (n=276) in Southern Brazil. Information regarding post-graduation training (specialization, master's or PhD), clinical experience (years since completing graduation) and place of work were investigated. The information regarding pulp vital therapies (materials for direct pulp capping; techniques for caries removal in deep cavities and strategies for indirect pulp capping) were collected by specific questions. Data were submitted to descriptive analysis and Exact Fischer Test. Response rate was 68% (187). The majority of dentists selected the calcium hydroxide (CH) as first material for direct (86.3%) and indirect (80.3%) pulp protection. Partial caries removal was reported by 61.9% of dentists. Less experienced clinical dentists choose partial caries removal more frequently (p=0.009), if compared with dentists graduated 10 years and up ago. The use of MTA was more common among professionals working at academic environment. Besides, MTA was not mentioned by professionals working exclusively in the public health service (p=0.003). In conclusion, the time since graduation influenced the clinical conduct related to caries removal. The choice of liner materials was influenced by dentists' workplace.

One major source of mental health problems in health professionals are personally demanding encounters at work. Thus, a crucial prevention focus is the development of emotional and social skills necessary to effectively manage interactions with clients, colleagues, and supervisors. The aim of our pre-post intervention field study was to evaluate an employee training in nonviolent communication (NVC) within a public health organization. A training group participated in a 3-day NVC training and completed questionnaires before and 3 months after training. Changes in NVC skills, empathic distress, empathy, and social stressors at work were compared with data from a control group without training. Additionally, we observed NVC-trained participants' communication behavior immediately before and after the intervention. We found a promotion of communication skills in training participants as evidenced by increased emotion verbalization behavior and enhanced use of NVC at work. Empathic distress declined, and an increase of social stressors at work was prevented by enhanced emotion verbalization. The findings demonstrate that NVC training can be an effective means to foster emotional and interpersonal skills and to prevent empathic distress and social stressors at work in individuals working in socioemotionally challenging settings. Possible causal mechanisms explaining the training effects are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

To characterize the current workforce of women urologists in the United States. An anonymous electronic survey was sent to all members of the Society of Women in Urology and all female non-Society of Women in Urology members of the American Urologic Association. The survey was distributed in January of 2015. Demographic, work, and personal life data were collected. Of 1563 e-mails with a link to our survey sent to women urologists in the United States, 365 surveys were completed for a 23% response rate. The average age of all participants was 39 years (range 25-73 years). Practicing women urologists had an average age of 44 years (range 32-65 years) compared to the average age (53 years) of all practicing urologists reported in the 2014 American Urologic Association Census. The majority of practicing female urologists live and work in a population of >1 million whereas a few live and work in rural areas. Practicing women urologists are most likely to work academic or group practice. Twenty percent of practicing women urologists reported working part-time, but almost 70% report working >50 hours/week. Women urologists in the United States are younger than their male counterparts and most work full-time in urban academic centers. Copyright © 2016 Elsevier Inc. All rights reserved.

Inefficiencies in the command approval process for publications and/or presentations negatively impact DoD Graduate Medical Education (GME) residency programs' ability to meet ACGME scholarly activity requirements. A preliminary review of the authored works approval process at Naval Medical Center San Diego (NMCSD) disclosed significant inefficiency, variation in process, and a low level of customer satisfaction. In order to facilitate and encourage scholarly activity at NMCSD, and meet ACGME requirements, the Executive Steering Council (ESC) chartered an interprofessional team to lead a Lean Six Sigma (LSS) Rapid Improvement Event (RIE) project. Two major outcome metrics were identified: (1) the number of authored works submissions containing all required signatures and (2) customer satisfaction with the authored works process. Primary metric baseline data were gathered utilizing a Clinical Investigations database tracking publications and presentations. Secondary metric baseline data were collected via a customer satisfaction survey to GME faculty and residents. The project team analyzed pre-survey data and utilized LSS tools and methodology including a "gemba" (environment) walk, cause and effect diagram, critical to quality tree, voice of the customer, "muda" (waste) chart, and a pre- and post-event value stream map. The team selected an electronic submission system as the intervention most likely to positively impact the RIE project outcome measures. The number of authored works compliant with all required signatures improved from 52% to 100%. Customer satisfaction rated as "completely or mostly satisfied" improved from 24% to 97%. For both outcomes, signature compliance and customer satisfaction, statistical significance was achieved with a p < 0.0001. This RIE project utilized LSS methodology and tools to improve signature compliance and increase customer satisfaction with the authored works approval process, leading to 100% signature compliance, a comprehensive longitudinal repository of all authored work requests, and a 97% "completely or mostly satisfied" customer rating of the process.

Pediatrics has consistently attracted a large number of women. Although the majority of practicing pediatricians are male, female pediatricians will soon constitute the majority. The challenge to balance personal and professional life is of particular concern to women, and part-time positions may provide a potential solution. To examine how many pediatricians currently work part-time, to examine trends in part-time employment from 1993 to present, to determine pediatric residents' interest in part-time employment, and to identify perceived barriers to part-time work. Two data sources were used for these analyses. The first was an American Academy of Pediatrics Periodic Survey from 1993 and 2000 asking a combined national sample of 3218 American Academy of Pediatrics members about their employment status. Multiple mailings were conducted for each survey producing an overall response rate of 62%. The second data source was a survey asking a national random sample of 500 pediatric residents completing training in 2000 about their job search experiences and attitudes toward part-time employment. Four mailings of this survey were completed, and responses were obtained from 71% of residents. The percentage of pediatricians working part-time increased from 11% in 1993 to 15% in 2000. This increase did not exceed what would be expected based on the rise in the percentage of pediatricians who are female from 36% in 1993 to 45% in 2000. On average, pediatricians working part-time provided 36% fewer direct patient care hours than full-time pediatricians (42 hours vs 27 hours). No statistically significant difference in direct patient care hours was apparent between male and female pediatricians working full-time. Female residents were more likely than male residents to consider part-time or reduced-hours positions (42% vs 14%) and to accept part-time or reduced-hours positions (14% vs 3%). Also, considerably more female residents (58%) than male residents (15%) indicated that they would be interested in arranging a part-time position within the next 5 years. The most commonly perceived barriers to working part-time by both male and female residents included loss of income (70%), reduction in job benefits such as health insurance (47%), and loan repayment (46%). When those who reported some interest in part-time employment were asked how they would spend their extra time, most reported that they would address family needs related to children (females: 92%; males: 63%). Finally, residents interested in working part-time were more likely to be without a position when surveyed than residents not interested in part-time work (15% vs 2%). The relative percentages of female pediatricians and pediatricians working part-time will likely continue to grow. As a result, the total direct patient care hours available for children may be reduced. Pediatric practices will benefit by better accommodating the needs of pediatricians to balance work and family goals, and future workforce projections and training decisions must begin taking part-time employment rates into account.

The SAGES Surgical Multimodal Accelerated Recovery Trajectory (SMART) Enhanced Recovery Task Force aims to increase awareness and provide tools for members to successfully implement enhanced recovery pathways (ERPs) to improve clinical outcomes and patient satisfaction. An initial step was to survey SAGES member on their knowledge, use, and impediments to enhanced recovery. An online survey designed by SMART committee members to define SAGES member's awareness and use of enhanced recovery principles and practice was emailed to all SAGES members. Reminders were sent 2 and 3 weeks later, encouraging completion of the survey. The web-based survey included 48 questions and took an estimated 20 min to complete. A total of 229 members completed the survey. Respondents were primarily general/MIS surgeons (82.6%) working in an urban location (85.5%), with a bell-shaped age distribution (median 35-44). Almost half regularly used some elements of ERPs (48.7%), but 30% were unfamiliar with the concept. Wide variety in the specific ERP elements used and discharge criteria were reported. The majority had to create and implement their own plan (70.4%). Roadblocks to implementation were inconsistencies with partners/covering physicians (56.3%), nursing education (46.6%), and resources (34.7%). When implemented, members saw improvements in length of stay (88%), patient satisfaction (54.7%), postoperative pain (53.3%), time to return of bowel function (52.7%), and readmissions (16.7%). A need for education and standardization was especially seen in preoperative care, with 74.4% fasting patients from midnight the night before surgery. Wide variations were also reported in pain management practices. An overwhelming majority (89%) reported that having a protocol endorsed by a national organization, such as SAGES, would help with implementation. From this survey of SAGES members, there is a need for education, tools, and standardized protocols to increase awareness, support implementation, and encourage wider utilization of ERP. The overwhelming majority stated having a protocol endorsed by a national organization, such as SAGES, would facilitate implementation.

Indigenous people make up approximately 3% of the total Australian population and score poorer on all health indices, including back pain. Chiropractors are well placed to alleviate back pain, yet there is no research that considers chiropractors' readiness to treat Indigenous patients. This study explores chiropractors` experience working with Indigenous Australians, describes perceived barriers and facilitators to chiropractors' participation in Indigenous Healthcare and their willingness to engage in cultural competency training. This study used a non-representative cross-sectional design and a convenience sample. Participants were recruited via email invitation to complete an online survey and encouraged to send the invitation on to colleagues. A 17-item online-survey measured demographic data, perceived barriers and facilitators related to caring for Indigenous Australians, participants` level of comfort when working in Indigenous health, and their willingness to participate in cultural competency programs to enhance their skills, knowledge and cultural capacity when engaging with Indigenous Australians. Analysis of the data included descriptive statistics as well as thematic analysis of qualitative free text. One hundred and twenty-five chiropractors participated in the survey. The majority of participants (86%, n  = 108) were employed in private practice. 62% of respondents were members of the Chiropractors' Association of Australia, 41% were Chiropractic and Osteopathic College of Australasia members. 60% of chiropractors considered that they had, or do treat Indigenous patients yet only 4% of respondents asked their patients if they identified as Indigenous. A majority of participants expressed a high level of 'comfort' or confidence in working with Indigenous people while only 17% of respondents had undertaken some form of cultural proficiency training. A majority of respondents (62.7%, n  = 74) expressed an interest in working with Indigenous Australians and a majority (91%, n  = 104) were willing to participate in training to develop Indigenous cultural competency. The study points to a need for chiropractors to have access to cultural proficiency training in order to develop the capability and confidence to engage respectfully with their Indigenous patients. This preliminary study has provided the researchers with valuable insights aiding the development and implementation of an Indigenous cultural proficiency program for chiropractors.

Nevada National Security Site Industrial Sites Project Closeout - 12498

Cabble, Kevin; Krauss, Mark; Matthews, Pat

The U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Site Office is responsible for environmental restoration (ER) at the Nevada National Security Site (NNSS). This includes remediation at Industrial Sites where past nuclear testing activities and activities that supported nuclear testing may have or are known to have resulted in the release of contaminants into the environment. Industrial Sites at the NNSS have included nuclear facilities that supported the nuclear rocket/missile development programs, gas stations, landfills, spill sites, ordnance sites, and numerous other waste disposal and release sites. The NNSS Industrial Sites activities neared completion at the endmore » of fiscal year 2011 while other activities required under the Federal Facility Agreement and Consent Order (FFACO) and part of the same NNSS ER Project are forecasted to extend to 2027 or beyond. With the majority of Industrial Sites corrective action units (CAUs) completed (more than 250 CAUs and over 1,800 corrective action sites), it was determined that an activity closeout process should be implemented to ensure that the work completed over the past 15 years is well documented in a comprehensive and concise summary. While the process used to close each individual CAU is described in approved documents, no single document describes in summary fashion the work completed to close the many individual Industrial Sites. The activity closeout process will be used to develop an Industrial Sites closeout document that describes these years of work. This document will summarize the number of Industrial Sites closed under the FFACO and provide general descriptions of projects, contaminants removed, and sites closed in place with corresponding Use Restrictions. Other pertinent information related to Industrial Sites work such as the project history, closure decisions, historical declarations, remediation strategies, and final CAU status will be included in the closeout document, along with a table listing each CAU and corresponding corrective action sites within each CAU. Using this process of conducting the activity closeout and developing a closeout document may prove useful for other ER projects within the DOE complex in describing how a long period of ER can be summarized in a single document. The NNSS Industrial Sites activities were completed over the span of 15 years and involved the investigation, cleanup or Use Restriction, and closure of more than 260 CAUs and over 1,800 sites. These activities will conclude in FY 2012 (with the exception of one CAU). In order to capture the work completed over this length of time and document decisions made during the activities, a closeout effort was initiated. The closeout will review the work conducted during the Industrial Sites activities and produce a single document that summarizes Industrial Sites activities. This closeout is being conducted at an interim stage in the overall NNSA/NSO ER Project since the Soils and UGTA activities will continue for a number of years, but the completion of the Industrial Sites project warrants conducting a closeout now while personnel are available and information is still current. The process followed by NNSA/NSO in conducing project closeout for the Industrial Sites portion of the ER program may prove useful within the DOE complex in demonstrating how a large ER project can be summarized.

Reminiscences of a journeyman scientist: studies of thermoregulation in non-human primates and humans.

PubMed

Adair, Eleanor Reed

2008-12-01

After graduating from Mount Holyoke College in 1948 where I majored in experimental psychology I worked at the College for 2 years with the Johns Hopkins Thermophysiological Unit. My graduate work later at the University of Wisconsin, centering on sensory psychology, culminated in my 1955 PhD thesis on human dark adaptation. I continued work in sensory psychology later with Neal Miller at Yale and then moved to the John B. Pierce Foundation--a Yale affiliate--where I began the studies of thermoregulation that constitute the center of my scientific career. Those studies were largely--later wholly--conducted using microwave energy as a thermal load and were thus published in Bioelectromagnetics even as I played an active role in the Bioelectromagnetics Society. In the beginning this work was centered on the responses of Squirrel Monkeys to thermal loads. Later, serving as Senior Scientist at the Air Force Research Laboratory at San Antonio, I completed an extensive analysis of thermal regulation in humans. I consider this work of special note inasmuch as the extraordinary human thermoregulatory ability was surely among the attributes that were paramount in initially separating humans from the other anthropoid primates.

The professional process portfolio (PPP) was adopted by the Maternal Child and Health Bureau (MCHB) as an 'innovation' in best practice for all Leadership in Education and Adolescent Health (LEAH) Training Programs; however it had not been formally evaluated. Thus the objective was to evaluate the utility of the PPP for graduates of the LEAH training program in terms of (1) how alumni have used, adapted, and applied it since completing fellowship, (2) what fellows learned or gained through completing it, and (3) how it can be improved for continued use in training programs. Graduates from six disciplines were asked via telephone or email to participate in a survey regarding their experience with the PPP. Descriptive statistics were generated for demographic characteristics and closed-choice questions. Responses to open-ended questions were analyzed by a team of faculty using framework analysis. Sixty-one graduates completed surveys. The majority (85%) found the PPP useful and utilized it post-graduation for multiple purposes in professional development: interviewing, training, and referencing previous work. Graduates recommended that the PPP be improved by making it electronic, discipline-specific, and providing earlier and more frequent instruction from faculty on expectations of creating it. Four themes emerged from the qualitative data analysis: accomplishment, experiential learning, skills and accountability, and a best practice of learning. The PPP was an effective personal learning tool for the majority of graduates and enhanced graduates' experiences. We highlight the ways that the PPP may facilitate the development of learning experiences associated with MCH leadership competence.

The Centre Block of Canada's Parliament buildings, National Historic Site of Canada is set to undergo a major rehabilitation project that will take approximately 10 years to complete. In preparation for this work, Heritage Conservation Services (HCS) of Public Services and Procurement Canada has been completing heritage documentation of the entire site which includes laser scanning of all interior rooms and accessible confined spaces such as attics and other similar areas. Other documentation completed includes detailed photogrammetric documentation of rooms and areas of high heritage value. Some of these high heritage value spaces present certain challenges such as accessibility due to the height and the size of the spaces. Another challenge is the poor lighting conditions, requiring the use of flash or strobe lighting to either compliment or completely eliminate the available ambient lighting. All the spaces captured at this higher level of detail were also captured with laser scanning. This allowed the team to validate the information and conduct a quality review of the photogrammetric data. As a result of this exercise, the team realized that in most, if not all cases, the photogrammetric data was more detailed and at a higher quality then the terrestrial laser scanning data. The purpose and motivation of this paper is to present these findings, as well provide the advantages and disadvantages of the two methods and data sets.

Several European studies showed that low organizational justice (i.e., procedural justice and interactional justice) was associated with major depressive disorders. In these studies, however, the diagnosis of major depressive disorders may be underestimated because they identified only individuals who visited a doctor and received a diagnosis. Moreover, these studies did not consider neurotic personality traits, which can affect the occurrence of major depressive disorders. The purpose of the present study was to investigate the cross-sectional association of organizational justice with major depressive episodes in the past 12 months more precisely in Japanese employees. A total of 425 males and 708 females from five branches of a manufacturing company in Japan completed self-administered questionnaires measuring organizational justice, other job stressors (i.e., job strain, social support at work, and effort-reward imbalance), neuroticism, and demographic characteristics. A web-based self-administered version of the computerized Composite International Diagnostic Interview Version 3.0 (CIDI 3.0) was used to assess major depressive episodes. Logistic regression analyses were conducted. In the univariate analysis, low procedural justice and low interactional justice were significantly associated with major depressive episodes in the past 12 months. After adjusting for other job stressors and demographic characteristics, only the association of interactional justice remained significant. The moderating effect of neuroticism on the association of organizational justice with major depressive episodes in the past 12 months was not significant. Low interactional justice may be associated with major depressive disorders regardless or other job stressors or neurotic personality traits.

Sex work has been seen as both a health and a social problem. However, there is a paucity of evidence on the longer term impact on health. We explored the health and career paths over a period of 15 years among women who have worked in the sex industry. A longitudinal study of sex workers recruited between 1986 and 1993 and followed for 15 years. Outcome data were obtained through interview, clinic records, or third parties. Clinic and community settings in London. We obtained outcome data on 130 (37%) of the original cohort of 354 women, with a combined follow up of 1247 years. Vital status, most recent occupation, duration of sex work, sexually transmitted infections (STI), major health problems. The majority (73/124, 59%) were still in the sex industry and had sold sex for a mean of 13.6 years. There were six deaths, a mortality of 4.8 per 1000 person years. Surviving women had a high cumulative risk (110 of 118, 93%) of STI. Past gonorrhoea was associated with pelvic inflammatory disease (RR 2.28, 95% CI 1.12 to 4.66) and infertility (RR 10.9, 95% CI 1.5 to 77.3). Other outcomes included mental health problems (38 of 97, 40%) and addiction (46 of 72, 64%). There were no significant differences in health outcomes between women who were still in the sex industry and those who had stopped. There was a high level of occupational mobility, and 31 women (of 84, 37%) had completed vocational or higher education, including eight to postgraduate level. Sex work is associated with excess mortality and morbidity including the sequelae of STI, mental health problems, and substance misuse. The relation between these health problems and sex work is complex.

The aims of this study were to explore factors associated with the job satisfaction of overseas-qualified nurses working in public hospitals in South Australia and to compare whether factors associated with job satisfaction of overseas nurses from English-speaking backgrounds differed from those from non-English-speaking backgrounds. Overseas-qualified nurses have become an essential part of the nursing workforce in Australia. Although this nurse population has different expectations and values in relation to their jobs when compared with local nurses, studies on job satisfaction among overseas nurses are scarce. A cross-sectional survey using the Job Satisfaction of Overseas-Qualified Nurses questionnaire was conducted in five major public hospitals in South Australia. One hundred and fifty-one overseas-qualified nurses completed the questionnaire. Four factors were found to influence job satisfaction: Supportive work environment, interpersonal relationships, communication in English, and salary and salary-related benefits. Communication in English was the predominant factor that was associated with job satisfaction in nurses from non-English-speaking backgrounds. This group of nurses also showed a negative correlation between length of stay in Australia and satisfaction with their work environment. Participants' responses to open-ended questions revealed issues relating to discrimination and racism. Supportive work environment, interpersonal relationships, communication in English, and salary and salary-related benefits were major factors associated with job satisfaction in overseas-qualified nurses in this study. Nurses from non-English-speaking backgrounds faced additional challenges in communication in the workplace and in dealing with issues of discrimination and racism. Nurses from non-English-speaking backgrounds need to be supported early in their employment, especially with their communication skills. Consideration also needs to be given to the education of local staff regarding cultural differences of overseas workers. © 2014 International Council of Nurses.

The purpose of this study is to explore the perceptions mathematics students have of the knowledge and skills they develop throughout their programme of study. It addresses current concerns about the employability of mathematics graduates by contributing much needed insight into how degree programmes are developing broader learning outcomes for students majoring in mathematics. Specifically, the study asked students who were close to completing a mathematics major (n = 144) to indicate the extent to which opportunities to develop mathematical knowledge along with more transferable skills (communication to experts and non-experts, writing, working in teams and thinking ethically) were included and assessed in their major. Their perceptions were compared to the importance they assign to each of these outcomes, their own assessment of improvement during the programme and their confidence in applying these outcomes. Overall, the findings reveal a pattern of high levels of students' agreement that these outcomes are important, but evidence a startling gap when compared to students' perceptions of the extent to which many of these - communication, writing, teamwork and ethical thinking - are actually included and assessed in the curriculum, and their confidence in using such learning.

Many clinical disciplines report high rates of burnout, which lead to low quality of care. Palliative care clinicians routinely manage patients with significant suffering, aiming to improve quality of life. As a major role of palliative care clinicians involves educating patients and caregivers regarding identifying priorities and balancing stress, we wondered how clinician self-management of burnout matches against the emotionally exhaustive nature of the work. We sought to understand the prevalence and predictors of burnout using a discipline-wide survey. We asked American Academy of Hospice and Palliative Medicine clinician members to complete an electronic survey querying demographic factors, job responsibilities, and the Maslach Burnout Inventory. We performed univariate and multivariate regression analyses to identify predictors of high rates of burnout. We received 1357 responses (response rate 30%). Overall, we observed a burnout rate of 62%, with higher rates reported by nonphysician clinicians. Most burnout stemmed from emotional exhaustion, with depersonalization comprising a minor portion. Factors associated with higher rates of burnout include working in smaller organizations, working longer hours, being younger than 50 years, and working weekends. We did not observe different rates between palliative care clinicians and hospice clinicians. Higher rated self-management activities to mitigate burnout include participating in interpersonal relationships and taking vacations. Burnout is a major issue facing the palliative care clinician workforce. Strategies at the discipline-wide and individual levels are needed to sustain the delivery of responsive, available, high-quality palliative care for all patients with serious illness.

Neurosurgical residents face a unique combination of challenges, including long duty hours, technically challenging cases, and uncertain employment prospects. We sought to assess the demographics, interests, career goals, self-rated happiness, and overall well-being of Canadian neurosurgery residents. A cross-sectional survey was developed and sent through the Canadian Neurosurgery Research Collaborative to every resident enrolled in a Canadian neurosurgery program as of April 1, 2016. We analyzed 76 completed surveys of 146 eligible residents (52% response rate). The median age was 29 years, with 76% of respondents being males. The most popular subspecialties of interest for fellowship were spine, oncology, and open vascular neurosurgery. The most frequent self-reported number of worked hours per week was the 80- to 89-hour range. The majority of respondents reported a high level of happiness as well as stress. Sense of accomplishment and fatigue were reported as average to high and overall quality of life was low for 19%, average for 49%, and high for 32%. Satisfaction with work-life balance was average for 44% of respondents and was the only tested domain in which significant dissatisfaction was identified (18%). Overall, respondents were highly satisfied with their choice of specialty, choice of program, surgical exposure, and work environment; however, intimidation was reported in 36% of respondents and depression by 17%. Despite a challenging residency and high workload, the majority of Canadian neurosurgery residents are happy and satisfied with their choice of specialty and program. However, work-life balance, employability, resident intimidation, and depression were identified as areas of active concern.

Torres, Fernanda; das Graças, Maria; Melo, Mota; Tosti, Antonella

2009-01-01

Nickel is the major cause of allergic contact dermatitis in the general population, both among children and adults, as well as in large occupational groups. This metal is used in numerous industrial and consumer products, including stainless steel, magnets, metal plating, coinage, and special alloys, and is therefore almost impossible to completely avoid in daily life. Nickel contact dermatitis can represent an important morbidity, particularly in patients with chronic hand eczema, which can lead to inability to work, a decrease in quality of life and significant healthcare expenses. Therefore, its management is of great importance. This article reviews diagnostic, preventive and therapeutic strategies in this field. PMID:21436967

A phase 2 study was initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This publication covers the first quarter of work. The major accomplishments were: the refurbishment of the high-pressure, high-temperature reactor autoclave, the completion of four coal liquefaction runs with Pittsburgh #8 coal, two each with and without sodium lignosulfonate surfactant, and the development of an analysis scheme for the product liquid filtrate and filter cake. Initial results at low reactor temperatures show that the addition of the surfactant produces an improvement in conversion yields and an increase in lighter boiling point fractions for the filtrate.

Acute Alcohol Consumption, Alcohol Outlets, and Gun Suicide

A case–control study of 149 intentionally self-inflicted gun injury cases (including completed gun suicides) and 302 population-based controls was conducted from 2003 to 2006 in a major US city. Two focal independent variables, acute alcohol consumption and alcohol outlet availability, were measured. Conditional logistic regression was adjusted for confounding variables. Gun suicide risk to individuals in areas of high alcohol outlet availability was less than the gun suicide risk they incurred from acute alcohol consumption, especially to excess. This corroborates prior work but also uncovers new information about the relationships between acute alcohol consumption, alcohol outlets, and gun suicide. Study limitations and implications are discussed. PMID:21929327

Watterson, Andrew; LaDou, Joseph

2003-01-01

Europe plays a major role in the international semiconductor industry, but has conducted few studies of the occupational health of its workers. An exception is in the United Kingdom, where, in two small studies, the Health and Safety Executive (HSE) evaluated some health effects of semiconductor work. Neither of these studies, largely restricted to Scotland, produced definitive results, and both were misused by industry to assert that they demonstrated no adverse health effect on workers. The results of the studies prompted semiconductor industry inspections recently completed by the HSE that included chip manufacturers in Scotland and other U.K. areas. The results of these inspections are disappointing.

Completing upper secondary education is associated with higher work participation and less health-related absence from work. Although these outcomes are closely interrelated, most studies focus on single outcomes, using cross-sectional designs or short follow-up periods. As such, there is limited knowledge of the long-term outcomes, and how paths for completers and non-completers unfold over time. In this paper, we use multi-state models for time-to-event data to assess the long-term effects of completing upper secondary education on employment, tertiary education, sick leave, and disability pension over twelve and a half years for young men. Baseline covariates and twelve and a half years of follow-up data on employment, tertiary education, sick leave and disability pension were obtained from national registries for all males born in Norway between 1971 and 1976 (n =184951). The effects of completing upper secondary education (by age 23) were analysed in a multi-state framework, adjusting for both individual and family level confounders. All analyses were done separately for general studies and vocational tracks. Completers do better on a range of outcomes compared to non-completers, for both fields of upper secondary education, but effects of completion change over time. The largest changes are for tertiary education and work, with the probability of work increasing reciprocally to the probability of education. Vocational students are quicker to transfer to the labour market, but tend to have more unemployment, sick leave and disability, and the absolute effects of completion on these outcomes are largest for vocational tracks. However, the relative effects of completion are larger for general studies. Completing upper secondary education increases long-term work participation and lowers health-related absence for young men, but effects diminish over time. Studies that have used shorter follow-up periods could be overstating the negative effects of dropout on labour market participation. Multi-state models are well suited to analyse data on work, education and health-related absence, and can be useful in understanding the dynamic aspects of these outcomes.

Background Ankylosing spondylitis (AS) is a chronic inflammatory arthritis which typically begins in early adulthood and impacts on healthcare resource utilisation and the ability to work. Previous studies examining the cost of AS have relied on patient-reported questionnaires based on recall. This study uses a combination of patient-reported and linked-routine data to examine the cost of AS in Wales, UK. Methods Participants in an existing AS cohort study (n = 570) completed questionnaires regarding work status, out-of-pocket expenses, visits to health professionals and disease severity. Participants gave consent for their data to be linked to routine primary and secondary care clinical datasets. Health resource costs were calculated using a bottom-up micro-costing approach. Human capital costs methods were used to estimate work productivity loss costs, particularly relating to work and early retirement. Regression analyses were used to account for age, gender, disease activity. Results The total cost of AS in the UK is estimated at £19016 per patient per year, calculated to include GP attendance, administration costs and hospital costs derived from routine data records, plus patient-reported non-NHS costs, out-of-pocket AS-related expenses, early retirement, absenteeism, presenteeism and unpaid assistance costs. The majority of the cost (>80%) was as a result of work-related costs. Conclusion The major cost of AS is as a result of loss of working hours, early retirement and unpaid carer’s time. Therefore, much of AS costs are hidden and not easy to quantify. Functional impairment is the main factor associated with increased cost of AS. Interventions which keep people in work to retirement age and reduce functional impairment would have the greatest impact on reducing costs of AS. The combination of patient-reported and linked routine data significantly enhanced the health economic analysis and this methodology that can be applied to other chronic conditions. PMID:26185984

Nurses who work in oncology settings may lack the knowledge and skills required for end-of-life (EoL) care. A clear understanding of nurses' perceptions of EoL care is crucial for the successful improvement of care for terminally ill patients with cancer. Although many studies have underlined nurses' perspectives on EoL care, this is the first such study conducted on oncology nurses in Qatar. This study primarily sought to measure nurses' perceptions of EoL care at the National Center for Cancer Care and Research (NCCCR) in Qatar. A quantitative, cross-sectional, self-reported study. Nurses at the NCCCR reported their perceptions of EoL care using the Frommelt Attitudes Toward Care of the Dying (FATCOD) scale, which consisted of 30 items scored on a five-point Likert scale. Seventy-eight nurses working in oncology settings completed the tool. Approximately one third (33-35%) of the participants had positive perceptions of EoL care. The majority (67%) of the participants were uncertain or ambivalent regarding EoL events and situations. There was no significant relationship between the participants' profiles and their perceptions of EoL care. However, very few of them had completed educational courses in death and dying. Nurses have an important impact on EoL care, and continuous education is necessary to improve their confidence when they work with dying patients and their families. An in-house programme to help nurses cope with compassionate exhaustion and humanistic and relational care is highly recommended.

Lambert, Richard

Tragedy of major proportion befell the family of Chris Scarfe and the University of Alberta, Canada, at 8 a.m. on July 20, 1988, when an errant car killed Chris instantly while he was out jogging on his way to work.Born in England, Chris graduated at the University of Durham, beginning his career in experimental petrology with Peter Wyllie at the University of Chicago. Returning to England, he completed a Ph.D. at the University of Leeds, assisting in the development of a high-pressure laboratory with Peter Harris. Appointed at the Univeristy of Alberta in 1972, he steadily developed a new facility, expanding the Department of Geology's embryonic high-pressure laboratory with equipment capable of pressures to 40 kbar and 2000°C. He also supervised research on basalts in the Atlantic Ocean, British Columbia, and the Northwest Territories. He spent 1987-1980 in the Geophysical Laboratory, where he met Eiichi Takahashi, establishing a friendship and a most fruitful working partnership. Quickly realizing t h e significance of very high-pressure equipment, Chris strenuously fought for a major equipment grant from the Natural Sciences and Engineering Research Council of Canada and secured it in time to have a Superpress delivered in February 1988, also utilizing support from the University. Quickly assembling a team of researchers, he brought the Superpress into immediate operation, producing diamonds within a month of start-up. Major discoveries concerning the range of stability of carbonates and on the petrogenesis of komatiites are well under way at pressures up to 200 kbar.

Occupational injury represents 7,7 at 69,9% of the total ocular traumatisms. They can be a major source of visuel loss and blindness. The aim is to study the epidemiology of work-related ocular injuries: objects frequencies,works most exposed. We performed a prospective study that interest 78 patients having a work-related ocular traumatism during a 4 months period. They were admitted at ocular emergeney All patients underwent an ophtalmologic examination completed with orbital radiography and echography. A medical and/or chirurgical appropriate treatment was institued. Occupationnal injury frequency was 9% of the whole ocular traumatisms in the same period. The mean age was 31 years. 55% of cases were under 30 years. 91% were male. Most exposed works were industrial and mecanical sectors In 70,5% of cases work-related eye injuries were caused by projectile objects. Most common lesion was corneal superficial foreign body (58%). Open globe injury was noted in 8%. 95% of patients had no eye protection at the time of the accident. 13% were blind or unilateral partially sighted (according to the OMS classification). The authors discussed the importance and different prevention strategies to prevent the risk of blindness and socio-economical cost of occupationnal accidents. There is a need for systematic periodic sensibilization to reduce these accidents and blindness.

Assessing the Effectiveness of Inquiry-based Learning Techniques Implemented in Large Classroom Settings

Steer, D. N.; McConnell, D. A.; Owens, K.

2001-12-01

Geoscience and education faculty at The University of Akron jointly developed a series of inquiry-based learning modules aimed at both non-major and major student populations enrolled in introductory geology courses. These courses typically serve 2500 students per year in four to six classes of 40-160 students each per section. Twelve modules were developed that contained common topics and assessments appropriate to Earth Science, Environmental Geology and Physical Geology classes. All modules were designed to meet four primary learning objectives agreed upon by Department of Geology faculty. These major objectives include: 1) Improvement of student understanding of the scientific method; 2) Incorporation of problem solving strategies involving analysis, synthesis, and interpretation; 3) Development of the ability to distinguish between inferences, data and observations; and 4) Obtaining an understanding of basic processes that operate on Earth. Additional objectives that may be addressed by selected modules include: 1) The societal relevance of science; 2) Use and interpretation of quantitative data to better understand the Earth; 3) Development of the students' ability to communicate scientific results; 4) Distinguishing differences between science, religion and pseudo-science; 5) Evaluation of scientific information found in the mass media; and 6) Building interpersonal relationships through in-class group work. Student pre- and post-instruction progress was evaluated by administering a test of logical thinking, an attitude toward science survey, and formative evaluations. Scores from the logical thinking instrument were used to form balanced four-person working groups based on the students' incoming cognitive level. Groups were required to complete a series of activities and/or exercises that targeted different cognitive domains based upon Bloom's taxonomy (knowledge, comprehension, application, analysis, synthesis and evaluation of information). Daily assessments of knowledge-level learning included evaluations of student responses to pre- and post-instruction conceptual test questions, short group exercises and content-oriented exam questions. Higher level thinking skills were assessed when students completed exercises that required the completion of Venn diagrams, concept maps and/or evaluation rubrics both during class periods and on exams. Initial results indicate that these techniques improved student attendance significantly and improved overall retention in the course by 8-14% over traditional lecture formats. Student scores on multiple choice exam questions were slightly higher (1-3%) for students taught in the active learning environment and short answer questions showed larger gains (7%) over students' scores in a more traditional class structure.

Total hip (THR) and knee (TKR) replacements increasingly are performed on younger people making return to work a salient outcome. This research evaluates characteristics of individuals with early and later return to work following THR and TKR. Additionally, at work limitations pre-surgery and upon returning to work, and factors associated with work limitations were evaluated. 190 THR and 170 TKR of a total 931 cohort participants were eligible (i.e., working or on short-term disability pre-surgery). They completed questionnaires pre-surgery and 1, 3, 6 and 12 months post-surgery that included demographics, type of occupation, and the Workplace Activity Limitations Scale (WALS). 166 (87%) and 144 (85%) returned to work by 12 months following THR and TKR, respectively. Early (1 month) return to work was associated with, male gender, university education, working in business, finance or administration, and low physical demand work. People with THR returned to work earlier than those with TKR. For both groups, less pain and every day functional limitations were associated with less workplace activity limitations at the time return to work. The majority of individuals working prior to surgery return to work following hip or knee replacement for osteoarthritis (OA) and experience fewer limitations at work than pre-surgery. The changing workforce dynamics and trends toward surgery at younger ages mean that these are important outcomes for clinicians to assess. Additionally, this is important information for employers in understanding continued participation in employment for people with OA. Copyright © 2013 Osteoarthritis Research Society International.

Telehealth refers to the provision of health information and services across a geographical distance. Little is known about the experiences of occupational therapists using this method of service delivery. The study explored the process of facilitating a telehealth intervention from the perspective of occupational therapists. Occupational therapists completed SOAP (Subjective, Objective, Assessment, and Plan) notes after facilitating group-based, teleconference-delivered fatigue management groups to people with multiple sclerosis. Notes were also documented after therapist team meetings. All SOAP notes and field notes were subjected to thematic analysis. Five major themes were identified. "Managing time" was the central theme and was facilitated by professional foundation and challenged by logistics. Managing time contributed to challenging work, which led to the realization that it can work! Based on study findings, the theory and research on clinical reasoning, professional development, and adult learning are relevant to developing curricula that prepare occupational therapists for using telehealth approaches in practice.

Observing the characteristics of giant exoplanets is possible with ground-based telescopes and modern observational methods. We are performing characterizations of multiple giant exoplanets based on 85 allotted nights of transit observations with the 2.3 m Wyoming Infrared Observatory using Sloan filters. In particular, constraints can be made on the atmospheres of our targets from the wavelength (in)dependence in the depth of the transit observations. We present early multiwavelength photometric results on the exoplanet HD 189733 b with comparison to literature sources to exemplify the methodology employed. In total, 15 exoplanets were observed across multiple wavelengths. The majority of the observing allotted to the project was completed as part of the 2017 Summer REU at the University of Wyoming. This work will significantly contribute to the growing number of observed atmospheres and influence interpretation of future WFIRST, JWST, and TESS targets.

Registered nurses with a diploma or an associate's degree are encouraged to return to school to earn a Bachelor of Science in Nursing degree. Until they return to school, many RNs have little need to regularly write, store, and retrieve work-related papers, but they are expected to complete the majority of assignments using a computer when in the student role. Personal information management (PIM) is a system of organizing and managing electronic information that will reduce computer clutter, while enhancing time use, task management, and productivity. This article introduces three PIM strategies for managing school work. Nesting is the creation of a system of folders to form a hierarchy for storing and retrieving electronic documents. Each folder, subfolder, and document must be given a meaningful unique name. Numbering is used to create different versions of the same paper, while preserving the original document.

The objective of the study was to assess absenteeism from work due to dizziness in patients referred to a tertiary centre. Consecutive patients with a paid employment completed the WHO Health and work Performance Questionnaire, including items on work absence in the past 7 days and 4 weeks, and the Dizziness Handicap Inventory. Of the 400 patients [55% females, mean age 46.3 years (SD 10.8), range 18-68 years], 46 (12%) indicated they were completely disabled to work due to dizziness, while 202 (51%) patients indicated they had worked less than expected due to dizziness. Patients with more disease-related disabilities had more absenteeism from work. Half of the patients who are referred to a tertiary centre for dizziness report work absenteeism due to their complaints, and 12% is completely disabled to work.

This systematic review aimed to explore factors known to influence intentions to stay and retention of nurse managers in their current position. Retaining staff nurses and recruiting nurses to management positions are well documented; however, there is sparse research examining factors that influence retention of nurse managers. Thirteen studies were identified through a systematic search of the literature. Eligibility criteria included both qualitative and quantitative studies that examined factors related to nurse manager intentions to stay and retention. Quality assessments, data extraction and analysis were completed on all studies included. Twenty-one factors were categorized into three major categories: organizational, role and personal. Job satisfaction, organizational commitment, organizational culture and values, feelings of being valued and lack of time to complete tasks leading to work/life imbalance, were prominent across all categories. These findings suggest that intentions to stay and retention of nurse managers are multifactoral. However, lack of robust literature highlights the need for further research to develop strategies to retain nurse managers.

Massive open online courses (MOOCs) are freely available online courses open to anyone who registers and typically are associated with thousands or hundreds of thousands of participants. Using an established online platform, the authors created and delivered a five-week MOOC aimed primarily at prospective veterinary students, but open to anyone with an interest in finding out more about the veterinary profession in general. 11,911 people signed up for the course, and of these, 8137 interacted in some way with the course and 1716 received a certificate of completion. The majority of participants (84 per cent) were female, and there was a wide age range (under 18 to over 65). Most participants were from North America or the UK. 65 per cent of those completing the entry survey were hoping or intending to work in the vet profession in the future, while 33 per cent were not. Qualitative data indicated that the course was helpful in aiding those undecided as to whether they wanted to be a veterinarian or not to decide one way or another whether they want to pursue veterinary medicine as a career. Furthermore, the course was seen as being a useful introduction to the veterinary profession even for those who had no intention of working in the field. British Veterinary Association.

In Malaysia, the construction sector is one of the important sectors that contribute to economic growth and employments. However, a major concern facing the construction industry is the growing rate of delays in project delivery. In the worse cases, the projects were abandoned due to some reasons when the contract period ended. Abandoned building defines as construction work that has been continuously stalled for 6 months or more, during the project completion period or beyond the scheduled date of completion. When the projects become abandoned, it gives an adverse effect on many parties such as the developer, contractor, consultant and also client. According to previous researchers, the abandonment of building causes a serious problem and need some mitigation plan to avoid this problem from occurring. This study will investigate the fundamental factors that contribute to the abandonment of building and projects in Malaysia based on the current data of the abandoned building in most states in Malaysia. The data was collected from the respondents who is in the construction industry and had experience working with abandoned housing project. Form the respondents perspective, it shows that the main factor contribute to the building abandonment is due to the financial problem facing by the developer company.

Functionalist villa Tugendhat deserves to be one of the UNESCO heritage sites. The author of this building was a prominent German architect, Ludwig Mies van der Rohe, who accepted the contract from Greta and Fritz Tugendhat. From today’s perspective, this building is one of the most important pre-war works of this architect. The 1928 architectural design was subsequently very quickly completed and the construction was completed in 1930. The Tugendhat family lived in a villa until 1938. During World War II it was confiscated by German occupation forces. At the end of the war, it was used by the Red Army and later served for the state. During this period, this building did not avoid warfare or later destruction of both the building and parts of the facility. The importance of this building was recognized in 1969, when the villa was placed on the State List of Cultural Monuments. In the 80’s was the first major renovation of the building, which is often criticized. The second, last reconstruction took place in the years 2010 - 2012. During these reconnaissance works there were also old, temporarily calming landslides, which were subsequently solved. For this reason, the site is suitable for geotourism as an example of architectural monuments versus geological subsoil.

Analysis of Non-Tropical Cyclone Induced Flood Events over South East Asia: Investigating Flood Frequency and Extremes in the Philippines

2013-12-01

Much work has been completed in analyzing Southeast Asia's tropical cyclone climatology and the associated flooding throughout the region. Although, an active and strong monsoon season also brings major flooding across the Philippines resulting in the loss of lives and significant economic impacts, only a limited amount of research work has been conducted to investigate the frequency and flood loss estimates of these non-tropical cyclone (TC) storms. In this study, using the TRMM 3-hourly rainfall product, tropical cyclone rainfall is removed to construct a non-TC rainfall climatology across the region. Given this data, stochastically generated rainfall that is both spatially and temporally correlated across the country is created to generate a longer historically-based record of non-TC precipitation. After defining the rainfall criteria that constitutes a flood event based on observed floods and TRMM data, this event definition is applied to the stochastic catalog of rainfall to determine flood events. Subsequently, a thorough analysis of non-TC flood extremes, frequency, and distribution is completed for the country of the Philippines. As a result, the above methodology and datasets provide a unique opportunity to further study flood occurrences and their extremes across most of South East Asia.

Time-varying mixed logit model for vehicle merging behavior in work zone merging areas.

2018-08-01

This study aims to develop a time-varying mixed logit model for the vehicle merging behavior in work zone merging areas during the merging implementation period from the time of starting a merging maneuver to that of completing the maneuver. From the safety perspective, vehicle crash probability and severity between the merging vehicle and its surrounding vehicles are regarded as major factors influencing vehicle merging decisions. Model results show that the model with the use of vehicle crash risk probability and severity could provide higher prediction accuracy than previous models with the use of vehicle speeds and gap sizes. It is found that lead vehicle type, through lead vehicle type, through lag vehicle type, crash probability of the merging vehicle with respect to the through lag vehicle, crash severities of the merging vehicle with respect to the through lead and lag vehicles could exhibit time-varying effects on the merging behavior. One important finding is that the merging vehicle could become more and more aggressive in order to complete the merging maneuver as quickly as possible over the elapsed time, even if it has high vehicle crash risk with respect to the through lead and lag vehicles.

Workers who incur permanent impairments or have ongoing medical restrictions due to injuries or illnesses sustained at work may require support from vocational rehabilitation programs in order to return to work. Vocational rehabilitation programs implemented within workers' compensation settings are costly, and effective service delivery has proven challenging. The Vocational Improvement Project, a 5.5-year pilot program beginning in 2008, introduced major changes to the Washington State workers' compensation-based vocational rehabilitation program. In the evaluation of this pilot program, set within a large complex system characterized by competing stakeholder interests, we assessed effects on system efficiency and employment outcomes for injured workers. While descriptive in nature, this evaluation provided evidence that several of the intended outcomes were attained, including: (1) fewer repeat referrals, (2) fewer delays, (3) increased choice for workers, and (4) establishment of statewide partnerships to improve worker outcomes. There remains substantial room for further improvement. Retraining plan completion rates remain under 60% and only half of workers earned any wages within two years of completing their retraining plan. Ongoing communication with stakeholders was critical to the successful conduct and policy impact of this evaluation, which culminated in a 3-year extension of the pilot program through June 2016.

Recently, the synchronization on multi-layer networks has drawn a lot of attention. In this work, we study the stability of the complete synchronization on duplex networks. We investigate effects of coupling function on the complete synchronization on duplex networks. We propose two approximation methods to deal with the stability of the complete synchronization on duplex networks. In the first method, we introduce a modified master stability function and, in the second method, we only take into consideration the contributions of a few most unstable transverse modes to the stability of the complete synchronization. We find that both methods work well for predicting the stability of the complete synchronization for small networks. For large networks, the second method still works pretty well.

Exploring experiences of Personal Support Worker education in Ontario, Canada.

There is growing attention to the training and education of Personal Support Workers, or PSWs, who work in community, home and long-term care settings supporting older people and people with disabilities. In Ontario, Canada, amid a volatile policy landscape, the provincial government launched an effort to standardise PSW education. Using qualitative methods, this study considered the question: What are the central educational issues reflected by students, working PSWs and key informants, and are they addressed by the PSW programme and training standards? Phase one was a public domain analysis completed between January and March 2014 and updated for major developments after that period. Phase two, completed between August 2014 and March 2015, included 15 key informant interviews and focus group discussions and mini-phone interviews with 35 working PSWs and current PSW students. According to the participants, the central educational issues are: casualisation of labour that is not conveyed in educational recruitment efforts, disconnect between theory and working conditions, overemphasis on long-term care as a career path, and variability of PSW education options. While the standards should help to address the final issue, they do not address the other key issues raised, which have to do with the structural organisation of work. There is thus a disconnect between the experiences of students, PSWs and key informants and the policy decisions surrounding this sector. This is particularly significant as education is often touted as a panacea for issues in long-term and community care. In fact, the curriculum of some of the PSW programmes, especially those in public college settings, is robust. Yet, the underlying issues will remain barring a structural overhaul of the organisation of long-term and community care sectors founded on a social revaluing of older people and the gendered work of care. © 2017 John Wiley & Sons Ltd.

[A survey on fatal work accidents based on Mortality Registry data: results of the Tuscany study on INAIL and RMR cases in the period 1992-2996].

Work-related deaths are important "sentinel events" of unsuccessful prevention. In Italy the most exhaustive source of such events is the National Fund for Occupational Diseases (INAIL), but the amount of cases from this source seems to be underestimated due to the fact that it refers only to cases occurred to subjects insured by the Fund. A previous survey estimated the real amount of work-related deaths 10-20% higher than that quantified by INAIL. This study evaluated the contribute of the two most important sources (INAIL and the Regional Mortality Registry of Tuscany-RMR) in estimating the number of these cases in Tuscany in the period 1992-96. Cases were identified from each source, and then it was applied a capture-recapture method to size the cases from work-related accident different from road accidents. RMR appeared to be the most exhaustive source with 72.3% completeness versus 56.4% completeness of INAIL source. Nevertheless the last one must be considered the primary source, more specific and accurate, and since few years also timely, than any other one. Work-related deaths from road accident represent 35.9% of INAIL cases but they are difficult to be identified from RMR and were not considered in this study. In conclusion the mortality data should be used for an epidemiologic surveillance system on work-related deaths not due to road accident in order to identify cases occurred to subjects not insured by INAIL (and therefore not defined by the Fund). These deaths are also important in terms of public health. Cases identified only from RMR, occurred in Tuscany in 1992-96, were 155: the vast majority occurred to farmers (mainly pensioners, and due to caterpillar upsetting), to bricklayers, to railway workers, to soldiers and to entrepreneurs.

These proceedings document a number of aspects of a big science facility and its impact on science, on technology, and on the continuing program of a major US research institution. The Zero Gradient Synchrotron (ZGS) was a 12.5 GeV weak focusing proton accelerator that operated at Argonne for fifteen years--from 1964 to 1979. It was a major user facility which led to new close links between the Laboratory and university groups: in the research program; in the choice of experiments to be carried out; in the design and construction of beams and detectors; and even in the Laboratory management. Formore » Argonne, it marked a major move from being a Laboratory dominated by nuclear reactor development to one with a stronger basic research orientation. The present meeting covered the progress in accelerator science, in the applications of technology pioneered or developed by people working at the ZGS, as well as in physics research and detector construction. At this time, when the future of the US research programs in science is being questioned as a result of the ending of the Cold War and plans to balance the Federal budget, the specific place of the National Laboratories in the spectrum of research activities is under particular examination. This Symposium highlights one case history of a major science program that was completed more than a decade ago--so that the further developments of both the science and the technology can be seen in some perspective. The subsequent activities of the people who had worked in the ZGS program as well as the redeployment of the ZGS facilities were addressed.

Understanding factors that contribute to a student’s selection of an exercise science-related major is important to student success, higher education and industry. This study sought to 1) better understand why undergraduate students study an exercise science-related major, 2) determine whether positive influences to study an exercise science-related major differ by academic classification, and 3) identify what student’s aspirations are after graduation. Department administrators from four-year colleges and universities offering an exercise science-related major in the Northwest Region of the United States (i.e., Idaho, Montana, Oregon, and Washington) were contacted. Cooperating department administrators were given self-reported questionnaires for students to complete using a snowball sampling method. A total of 388 participants completed the questionnaire. Interest in the subject and potential job opportunities were the most common reasons to study an exercise science-related major. Self-reported Holland’s codes identified that realistic and social personalities were most prevalent among participants. Seniors rated a friend’s influence and college advisors as stronger influences to study an exercise science-related major compared to freshmen. Pay in the field was a stronger influence for freshmen to study an exercise science-related major than for fifth-year seniors, whereas freshmen were less influenced by introductory courses to study an exercise-science related major than fifth-year seniors. The majority of undergraduate students studying an exercise science-related major planned on attending graduate school after completing their baccalaureate degree. These findings can be used to help guide undeclared students and better serve undergraduates enrolled in an exercise science-related major. PMID:28966716

[Structural Equation Modeling of Quality of Work Life in Clinical Nurses based on the Culture-Work-Health Model].

PubMed

Kim, Miji; Ryu, Eunjung

2015-12-01

The purpose of this study was to construct and test a structural equation model of quality of work life for clinical nurses based on Peterson and Wilson's Culture-Work-Health model (CWHM). A structured questionnaire was completed by 523 clinical nurses to analyze the relationships between concepts of CWHM-organizational culture, social support, employee health, organizational health, and quality of work life. Among these conceptual variables of CWHM, employee health was measured by perceived health status, and organizational health was measured by presenteeism. SPSS21.0 and AMOS 21.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factors affecting quality of work life among clinical nurses. The goodness-of-fit statistics of the final modified hypothetical model are as follows: χ²=586.03, χ²/df=4.19, GFI=.89, AGFI=.85, CFI=.91, TLI=.90, NFI=.89, and RMSEA=.08. The results revealed that organizational culture, social support, organizational health, and employee health accounted for 69% of clinical nurses' quality of work life. The major findings of this study indicate that it is essential to create a positive organizational culture and provide adequate organizational support to maintain a balance between the health of clinical nurses and the organization. Further repeated and expanded studies are needed to explore the multidimensional aspects of clinical nurses' quality of work life in Korea, including various factors, such as work environment, work stress, and burnout.

Post-Closure Land Jurisdiction Transfer to the US Fish and Wildlife Service at Rocky Flats: Surviving the Safari Through Old Records and Other Lessons Learned

Schiesswohl, S.; Hanson, M.

The U.S. Department of Energy's (DOE's) Rocky Flats Site (Rocky Flats), located near Denver, Colorado, was listed on the Comprehensive Environmental Response, Compensation, and Liability Act National Priorities List (NPL) in 1989. Subsequent cleanup and closure activities were completed in October 2005 and the final remedy was selected in September 2006. The remedy is 'no further action' for the generally un-impacted Peripheral Operable Unit (OU), formerly known as the Buffer Zone, and institutional and physical controls with continued monitoring for the Central OU, formerly the industrialized area. The Peripheral OU has been deleted from the NPL and jurisdiction over themore » majority of land in that OU (3,953 acres) was transferred to the U.S. Fish and Wildlife Service (USFWS) on July 12, 2007, to establish the Rocky Flats National Wildlife Refuge. The remaining approximately 929 acres in the Peripheral OU were retained by DOE's Office of Legacy Management where outstanding mineral leases and mining operations exist. As mineral rights are purchased or mining operations and mineral leases are completed and fully reclaimed, jurisdiction of portions of the 929 acres will also be transferred to USFWS for inclusion into the refuge. During the almost 2 years since cleanup and closure work was completed at Rocky Flats, DOE and USFWS have worked the specific legal parameters, timing, and constraints of the 3,953-acre transfer. Many lessons have been learned, based on these early experiences. (authors)« less

The aim of this study is to determine the prevalence rates of depressive, anxiety and PTSDs, and the risk factors for psychological symptoms at 6 years after occupational injury. This longitudinal study followed workers who were occupationally injured in 2009. Psychological symptoms and return to work were assessed at 3 and 12 months after injury. Injured workers who had completed the initial questionnaire survey at 3 or 12 months after injury were recruited. A self-administered questionnaire was mailed to the participants. For workers with high Brief Symptom Rating Scale and Post-traumatic Symptom Checklist scores, an in-depth psychiatric evaluation was performed using the Mini-international Neuropsychiatric Interview. A total of 570 workers completed the questionnaire (response rate, 28.7%). Among them, 243 (42.6%) had high psychological symptom scores and were invited for a phone interview; 135 (55.6%) completed the interview. The estimated rates of major depression and post-traumatic stress disorder (PTSD)/partial PTSD were 9.2 and 7.2%, respectively, and both these rates were higher at 6 years after injury than at 12 months after injury (2.0 and 5.1%). After adjustment for family and social factors, the risk factors for high psychological scores were length of hospitalization immediately after injury, affected physical appearance, repeated occupational injuries, unemployment, and number of quit jobs after the injury. At 6 years after occupational injury, the re-emergence of psychiatric disorders was observed. Relevant factors for poor psychological health were severity of injury and instability of work. Periodic monitoring of psychological and physical health and economic stability are warranted.

Prospective memory (PM) is the ability to remember to carry out future intentions when prompted by a cue, and previous studies have suggested that emotional PM cues may enhance PM performance. This study examined the influence of emotional cues on PM performance in patients with schizophrenia and major depressive disorder. All participants were required to respond to emotional or neutral PM cues while completing a working memory task. Healthy participants showed improved PM performance with positive and negative cues. Patients with major depressive disorder were not impaired in PM performance and showed significant improvement in PM performance when cued by negative but not positive cues. Patients with schizophrenia had impaired PM performance irrespective of cue emotionality. In addition, the majority of patients with schizophrenia failed to show an emotional enhancement effect, and only those who had normal arousal ratings for negative PM cues showed emotional enhancement effect. These findings show for the first time that patients with schizophrenia exhibit PM impairments even with emotional cues, and suggest that arousal may be a critical factor for schizophrenia patients to utilize emotional cues to facilitate execution of future actions. In patients with major depressive disorder, our findings suggest that the negative bias in attention and retrospective memory may also extend to memory for future actions. These novel findings have both theoretical and clinical implications. Copyright © 2018. Published by Elsevier B.V.

Objectives Family engagement in home visiting (HV), as indicated by length of enrollment, is a major challenge as most families do not stay enrolled for the intended duration prescribed by HV models. This study examined maternal and visitor emotional well-being as factors for maternal satisfaction with the program in addressing reasons for enrolling in HV and program engagement and the role of their working alliance with the visitor as a mediator of this. Methods Longitudinal data were collected from 148 mothers and 54 visitors in 21 HV programs. Mothers completed surveys shortly after enrolling and 6 months later to assess attributes of the working alliance with their visitor. Visitors completed a survey to assess work-related well-being. HV program data were used to measure engagement. Results Mothers enrolled for multiple, diverse reasons, most often to promote child development and parenting (96%). Mothers' satisfaction with program efforts to address reasons for enrollment was highest for parenting (79%) and lowest for jobs and education (30%). Results of the mediational path model indicated that ratings of the visitor on goal alignment were positively associated with engagement. Maternal emotional availability and visitor work-related emotional exhaustion were negatively associated with engagement. Exploratory analyses suggested that ratings of the visitor on goal alignment were a stronger predictor of engagement for mothers with low emotional availability compared to other mothers. Conclusions for Practice Visitor alignment with mothers on goals and responsiveness to reasons for enrolling appear to be effective in promoting engagement. Individualizing services to reflect maternal goals and emotional capacity may be important strategies to address engagement challenges.

Abstract Background The migration of health professionals can have a profound impact on health systems around the globe. The International Organization for Migration's (IOM) Mobility of Health Professionals Research Project (MoHProf) aimed to improve knowledge about the migration of healthcare professionals and understand migration intentions and factors influencing the migration of medical and nursing students. Objectives The study aimed to determine the proportion of nursing and medical students who were intending to emigrate, their attitudes and beliefs about, and the factors influencing their decision to emigrate. Method This study was conducted at three medical schools and one nursing school in South Africa (n = 298) amongst 260 medical and 38 nursing students. One hundred and twenty-five students were in the final year of their studies and 143 were in their prefinal year. Thirty students did not indicate the year of their studies. Every student present on the day of data collection completed a questionnaire comprising psychometric and survey-based questions. Descriptive and inferential statistics were used to analyse the data. Results More than a third (37%) of the respondents intended to work or specialise abroad. The majority of medical (58.9%) and nursing (66.6%) students intended to leave SA within five years of completing their medical or nursing studies. The perception of poor working conditions within the health sector, such as long work hours, high patient loads, inadequate resources and occupational hazards, influenced medical students to consider emigrating from South Africa. Conclusion The high number of medical and nursing students intending to emigrate requires a reassessment of effectiveness of retention strategies for doctors and nurses in the South African healthcare system and actions to improve working conditions in the public healthcare sector.

Tobacco is a major risk factor contributing to Indigenous health disparities. Art may be a powerful and transformative tool to enable health providers to develop targeted messages for tobacco control. Indigenous and non-Indigenous staff, working in Indigenous tobacco control, attended a two-hour workshop, and were led through a process to create individual artworks. Participants completed surveys before and after the workshop. Scales compared understandings of how art can be used in tobacco control, and the likelihood of utilising arts in future programs. Three pairs of Indigenous and non-Indigenous researchers analysed the artworks, using the Four Frames (New South Wales Board of Studies), explored themes, and developed a model. Nineteen participants completed both surveys; 17 artworks were analysed. Pre- to post-workshop increases in "understanding" about the use of arts (p<0.00001) for tobacco control, and "likelihood" of use of arts in the next six months (p<0.006) were significant. Participants expressed personal and professional benefits from the workshop. Artworks demonstrated themes of optimism, the strength of family and culture, smoking as a barrier, resilience, recovery and urgency. The workshop increased the understanding and likelihood of using the arts for tobacco control. Artworks revealed contemporary challenges impacting on equity; health staff expressed optimism for being engaged in their work. SO WHAT?: The Framework Convention for Tobacco Control supports novel techniques to increase the reach and relevance of health messages for diverse populations. This study successfully demonstrated how a novel, positively-framed art-based technique proved to be advantageous for health professionals, working in an area of Indigenous tobacco control, where behavioural change can be complex.

In this study, we aimed to determine the perspectives of medical and radiation oncologists regarding consolidation radiotherapy in patients with a complete response after chemotherapy for Hodgkin’s and non-Hodgkin’s lymphomas. The survey was designed to identify demographic and occupational features of medical and radiation oncologists and their views on application of consolidation radiotherapy in their clinical practices, as based on a five-point Likert scale (never, rarely, sometimes, often, and always). The study covered 263, out of 935, physicians working in the oncology field as either medical or radiation oncologists; the rate of return on the invitations to participate was 28%. The majority of the participants were male radiation oncologists, with a duration of between 5 and 10 years of work as a university hospital official, and the mean age was 38 ± 14 (years). Although the most commonly followed international guidelines were NCCN, among the physicians, the majority of the respondents suggested that the guidelines were unclear regarding recommendations for consolidative radiotherapy. The administered dose for consolidative radiotherapy in lymphoma patients was indicated as 40 Gy by 49% of all the physicians and the most common cause of hesitancy concerning consolidative radiation treatment was the risk of secondary malignancies as a long-term adverse effect (54%). In conclusion, we suggest that medical oncologists could be most active in the treatment of lymphoma through a continuous training program about lymphomas and current national guidelines.

Example-based learning using worked examples can foster clinical reasoning. Worked examples are instructional tools that learners can use to study the steps needed to solve a problem. Studying worked examples paired with completion examples promotes acquisition of problem-solving skills more than studying worked examples alone. Completion examples are worked examples in which some of the solution steps remain unsolved for learners to complete. Providing learners engaged in example-based learning with self-explanation prompts has been shown to foster increased meaningful learning compared to providing no self-explanation prompts. Concept mapping and concept map study are other instructional activities known to promote meaningful learning. This study compares the effects of self-explaining, completing a concept map and studying a concept map on conceptual knowledge and problem-solving skills among novice learners engaged in example-based learning. Ninety-one physiotherapy students were randomized into three conditions. They performed a pre-test and a post-test to evaluate their gains in conceptual knowledge and problem-solving skills (transfer performance) in intervention selection. They studied three pairs of worked/completion examples in a digital learning environment. Worked examples consisted of a written reasoning process for selecting an optimal physiotherapy intervention for a patient. The completion examples were partially worked out, with the last few problem-solving steps left blank for students to complete. The students then had to engage in additional self-explanation, concept map completion or model concept map study in order to synthesize and deepen their knowledge of the key concepts and problem-solving steps. Pre-test performance did not differ among conditions. Post-test conceptual knowledge was higher (P < .001) in the concept map study condition (68.8 ± 21.8%) compared to the concept map completion (52.8 ± 17.0%) and self-explanation (52.2 ± 21.7%) conditions. Post-test problem-solving performance was higher (P < .05) in the self-explanation (63.2 ± 16.0%) condition compared to the concept map study (53.3 ± 16.4%) and concept map completion (51.0 ± 13.6%) conditions. Students in the self-explanation condition also invested less mental effort in the post-test. Studying model concept maps led to greater conceptual knowledge, whereas self-explanation led to higher transfer performance. Self-explanation and concept map study can be combined with worked example and completion example strategies to foster intervention selection.

Prompting Technology and Persons With Dementia: The Significance of Context and Communication.

2018-06-12

Smart home auto-prompting has the potential to increase the functional independence of persons with dementia (PWDs) and decrease caregiver burden as instrumental activities of daily living (IADLs) are completed at home. To improve prompting technologies, we sought to inductively understand how PWDs responded to auto-prompting while performing IADL tasks. Fifteen PWDs completed eight IADLs in a smart home testbed and received a hierarchy of verbal auto-prompts (indirect, direct, multimodal) as needed for task completion. Two researchers viewed archived videos and recorded the observed behaviors of the PWDs and their reflections watching the PWDs. Using qualitative descriptive methods, an interdisciplinary analytic team reviewed transcripts and organized data into themes using content analysis. Context and Communication emerged as the major themes, suggesting that positive user experiences will require auto-prompting systems to account for a multitude of contextual factors (individual and environmental) such as level of cognitive impairment, previous exposure to task, and familiarity of environment. Communicating with another human rather than an automated prompting system may be important if individuals begin to exhibit signs of stress while completing activities. Additional work is needed to create auto-prompting systems that provide specific, personalized, and flexible prompts. Holistic conceptualization of "successful task completion" is needed and a positive end-user experience will be key to utility. Such systems will benefit from including positive reinforcement, training, and exploration of how, and whether, direct human involvement can be minimized during the provision of in-home care.

The proposed interoceanic canal will connect the Caribbean Sea with the Pacific Ocean, traversing Lake Nicaragua, the major freshwater reservoir in Central America. If completed, the canal would be the largest infrastructure-related excavation project on Earth. In November 2015, the Nicaraguan government approved an environmental and social impact assessment (ESIA) for the canal. A group of international experts participated in a workshop organized by the Academy of Sciences of Nicaragua to review this ESIA. The group concluded that the ESIA does not meet international standards; essential information is lacking regarding the potential impacts on the lake, freshwater and marine environments, and biodiversity. The ESIA presents an inadequate assessment of natural hazards and socioeconomic disruptions. The panel recommends that work on the canal project be suspended until an appropriate ESIA is completed. The project should be resumed only if it is demonstrated to be economically feasible, environmentally acceptable, and socially beneficial.

Prior work has described the experience of caregiving in idiopathic pulmonary fibrosis, but the effect on caregivers in interstitial lung disease (ILD) has not been explored. Describe the burden, resilience, and health related quality of life (HRQoL) of caregivers of people with ILD. In a mixed methods study, ILD caregivers completed questionnaires and participated in focus groups. A qualitative thematic analysis of the focus group transcripts was conducted. Thirty seven caregivers completed the survey, and 15 participated in the focus groups. 65% were female; the average age was 66 (SD = 13). The mean Short Form-36 role emotional and mental health scores were 18 (SD = 4) and 46 (SD = 7). The focus groups identified 4 major themes: emotional burden, changes in relationship, coping strategies, and unmet needs of caregivers. Caregiving for patients with ILD significantly impairs HRQoL, particularly, emotional health. Increasing resources could improve the caregiving experience in ILD. Copyright © 2018 Elsevier Inc.

2015-12-03

This work reports a new method of synthesizing anhydrous lithium sulfide (L i2S) nanocrystals and demonstrates their potential as cathode materials for advanced rechargeable batteries. Li 2S is synthesized by reacting hydrogen sulfide (H 2S) with lithium naphthalenide (Li-NAP), a thermodynamically spontaneous reaction that proceeds to completion rapidly at ambient temperature and pressure. The process completely removes H 2S, a major industrial waste, while cogenerating 1,4-dihydronaphthalene, itself a value-added chemical that can be used as liquid fuel. The phase purity, morphology, and homogeneity of the resulting nanopowders were confirmed by X-ray diffraction and scanning electron microscopy. The synthesized Li 2Smore » nanoparticles (100 nm) were assembled into cathodes, and their performance was compared to that of cathodes fabricated using commercial Li 2S micropowders (1–5 μm). As a result, electrochemical analyses demonstrated that the synthesized Li 2S were superior in terms of (dis)charge capacity, cycling stability, output voltage, and voltage efficiency.« less

The human genome contracts again.

2013-09-01

The number of human genomes that have been sequenced completely for different individuals has increased rapidly in recent years. Storing and transferring complete genomes between computers for the purpose of applying various applications and analysis tools will soon become a major hurdle, hindering the analysis phase. Therefore, there is a growing need to compress these data efficiently. Here, we describe a technique to compress human genomes based on entropy coding, using a reference genome and known Single Nucleotide Polymorphisms (SNPs). Furthermore, we explore several intrinsic features of genomes and information in other genomic databases to further improve the compression attained. Using these methods, we compress James Watson's genome to 2.5 megabytes (MB), improving on recent work by 37%. Similar compression is obtained for most genomes available from the 1000 Genomes Project. Our biologically inspired techniques promise even greater gains for genomes of lower organisms and for human genomes as more genomic data become available.

The experimental work carried out under this contract is a continuation of that originally performed under Contracts NAS5-20062 and NAS5-26739. The data analyzed are from the Max-Planck Institut/Univ. of Maryland experiment on ISEE-1 and ISEE-3. Each spacecraft experiment consists of a nearly identical set of three sensors (designated the ULECA, ULEWAT, and ULEZEQ sensors) designed to measure the energy spectra and composition of suprathermal and energetic ions over a broad energy range (less than 3 keV/e to more than 20 MeV/nucleon). Since the launch of ISEE's 2 and 3, the MPI/Univ. of Maryland experiments have generally performed as expected except for a partial failure of the ULEWAT sensor on ISEE-1 in August 1978. A number of scientific studies have either been completed, initiated or are at various stages of completion. A brief summary of Primary Results is given, followed by a more detailed summary of the major accomplishments at the Univ. of Maryland.

Diagnostic radiology is the major contributor to the total dose of the population from all artificial sources. In order to reduce radiation exposure and optimize diagnostic x-ray image quality, it is necessary to increase the quality and efficiency of quality assurance (QA) and audit programs. This work presents a web application providing completely new QA solutions for x-ray modalities and facilities. The software gives complete online information (using European standards) with which the corresponding institutions and individuals can evaluate and control a facility's Radiation Safety and QA program. The software enables storage of all data in one place and sharing the same information (data), regardless of whether the measured data is used by an individual user or by an authorized institution. The software overcomes the distance and time separation of institutions and individuals who take part in QA. Upgrading the software will enable assessment of the medical exposure level to ionizing radiation.

Safeguarding against substandard/counterfeit drugs: mitigating a macroeconomic pandemic.

Wertheimer, Albert I; Norris, Jeremiah

2009-03-01

Counterfeiting and the sale of substandard pharmaceutical products can no longer be ignored. At 10% of global trade, counterfeiting is affecting many countries, causing serious downstream expenses and resource shortages. To describe the nature and impact of drug product counterfeiting and substandard product sale and to present strategies that may have value in ameliorating these phenomena. A literature review was conducted, supplemented by interviews of key leaders/experts in the field and the search of relevant web sites. All of the data were combined, integrated, and coordinated to present the complete picture of this problem. In addition to known corruption in some of the least developed countries, the trail through developed countries was detected. This report identifies means to detect faulty products and describes efforts toward resisting and ending these corrupt practices. Counterfeit drugs, if not stopped, can be responsible for a macroeconomic pandemic where major portions of some populations may be too ill to work and where the health sector resources are completely overwhelmed, as with the case of HIV/AIDS.

2018-04-05

Case review and discussion at multidisciplinary team meetings (MDTMs) have evolved into standard practice in cancer care with the aim to provide evidence-based treatment recommendations. As a basis for work to optimize the MDTMs, we investigated participants' views on the meeting function, including perceived benefits and barriers. In a cross-sectional study design, 244 health professionals from south Sweden rated MDTM meeting structure and function, benefits from these meetings and barriers to reach a treatment recommendation. The top-ranked advantages from MDTMs were support for patient management and competence development. Low ratings applied to monitoring patients for clinical trial inclusion and structured work to improve the MDTM. Nurses and cancer care coordinators did less often than physicians report involvement in the case discussions. Major benefits from MDTM were reported to be more accurate treatment recommendations, multidisciplinary evaluation and adherence to clinical guidelines. Major barriers to a joint treatment recommendation were reported to be need for supplementary investigations and insufficient pathology reports. Health professionals' report multiple benefits from MDTMs, but also define areas for improvement, e.g. access to complete information and clarified roles for the different health professions. The emerging picture suggests that structures for regular MDTM evaluations and increased focus on patient-related perspectives should be developed and implemented.

2016-01-01

There is some research on the impact of open-ward unit design on the health of babies and the stress experienced by parents and nurses in neonatal intensive care units. However, few studies have explored the factors associated with nurse stress and work satisfaction among nurses practicing in open-ward neonatal intensive care units. The purpose of this study was to examine what factors are associated with nurse stress and work satisfaction among nurses practicing in an open-ward neonatal intensive care unit. A cross-sectional correlational design was used in this study. Participants were nurses employed in a 34-bed open-ward neonatal intensive care unit in a major university-affiliated hospital in Montréal, Quebec, Canada. A total of 94 nurses were eligible, and 86 completed questionnaires (91% response rate). Descriptive statistics were computed to describe the participants' characteristics. To identify factors associated with nurse stress and work satisfaction, correlational analysis and multiple regression analyses were performed with the Nurse Stress Scale and the Global Work Satisfaction scores as the dependent variables. Different factors predict neonatal intensive care unit nurses' stress and job satisfaction, including support, family-centered care, performance obstacles, work schedule, education, and employment status. In order to provide neonatal intensive care units nurses with a supportive environment, managers can provide direct social support to nurses and influence the culture around teamwork.

Frankenfeld, Cara L.; Bases, Jessica; Espina, Virginia; Liotta, Lance A.

2014-01-01

What early experiences attract students to pursue an education and career in science, technology, engineering, and mathematics (STEM)? Does hands-on research influence them to persevere and complete a major course of academic study in STEM? We evaluated survey responses from 149 high school and undergraduate students who gained hands-on research experience in the 2007–2013 Aspiring Scientists Summer Internship Programs (ASSIP) at George Mason University. Participants demonstrated their strong interest in STEM by volunteering to participate in ASSIP and completing 300 h of summer research. The survey queried extracurricular experiences, classroom factors, and hands-on projects that first cultivated students’ interest in the STEM fields, and separately evaluated experiences that sustained their interest in pursuing a STEM degree. The majority of students (65.5%, p < 0.0001) reported extracurricular encounters, such as the influence of a relative or family member and childhood experiences, as the most significant factors that initially ignited their interest in STEM, while hands-on lab work was stated as sustaining their interest in STEM (92.6%). Based on these findings collected from a cohort of students who demonstrated a strong talent and interest in STEM, community-based programs that create awareness about STEM for both children and their family members may be key components for igniting long-term academic interest in STEM.

Energization and transport of ions of ionospheric origin in the terrestrial magnetosphere

NASA Technical Reports Server (NTRS)

Waite, J. Hunter JR.

1995-01-01

The work of this grant has been predominantly focused on ion outflows from two data sets: Prognoz 7 and Dynamics Explorer. The Prognoz analysis studied ion densities, temperatures, and flow velocities in the magnetotail. The work performed under this contract consisted of developing a program to load the raw data, computing the background subtraction of a strong sun pulse, and using the net count to calculate the low order moments of the distribution function. The study confirms the results of ISEE with regard to the supply of plasma from the cusp as a major source of plasmasheet plasma and goes beyond this to discuss the use of ion velocities as a way to examine the motions of the magnetotail. The abstract of the work to be reported is included as an appendix. The work on the DE/Retarding Ion Mass Spectrometer is separated into two categories: (1) classification of low-energy ion flows from high-latitudes, and (2) studies of the polar wind. Major publications resulting from this work are also included as an appendix to this report. The polar wind is in a category by itself as a result of the thermal escape of hydrogen and helium because of ambipolar diffusion through the heavier, oxygen-dominated topside ionosphere. The analysis of the polar wind reports the flux variability as a function of season, magnetic activity, etc. Much effort has been expended under this grant to complete a follow on study of the thermal structure of the polar wind. Extensive display tools and analysis software have been developed and used in an attempt to carry out this thermal analysis. The present work uses a constrained fit scheme that combines the ion densities and flow velocities derived from Chandler et al. and a spacecraft potential derived from an empirical relation to the total ion density to determine the remaining fit parameter, the ion temperature, via a least squares fit to the RIMS data.

Muscular and Aerobic Fitness, Working Memory, and Academic Achievement in Children.

This study investigated the relationship between aerobic and muscular fitness with working memory and academic achievement in preadolescent children. Seventy-nine 9- to 11-yr-old children completed an aerobic fitness assessment using a graded exercise test; a muscular fitness assessment consisting of upper body, lower body, and core exercises; a serial n-back task to assess working memory; and an academic achievement test of mathematics and reading. Hierarchical regression analyses indicated that after controlling for demographic variables (age, sex, grade, IQ, socioeconomic status), aerobic fitness was associated with greater response accuracy and d' in the 2-back condition and increased mathematic performance in algebraic functions. Muscular fitness was associated with increased response accuracy and d', and longer reaction time in the 2-back condition. Further, the associations of muscular fitness with response accuracy and d' in the 2-back condition were independent of aerobic fitness. The current findings suggest the differential relationships between the aerobic and the muscular aspects of physical fitness with working memory and academic achievement. With the majority of research focusing on childhood health benefits of aerobic fitness, this study suggests the importance of muscular fitness to cognitive health during preadolescence.

Student mobility within Europe is encouraged by the EU's 'Bologna process' and financially supported by the Socrates programme. However, relatively few UK nursing students travel to Europe for study. To compare the willingness to study or work abroad and the perceived barriers and benefits of doing so, amongst students in England and Spain. Third year nursing students completed a 15 item questionnaire on work and study abroad. Spanish students were younger than UK students, had fewer family commitments, and better language skills. There was little difference between Spanish and UK students in wanting to study abroad, UK students named English speaking countries as likely destinations. Spanish students named Italy; the UK and USA were also popular. Perceived barriers for UK students were funding, family, and language. Family commitments were not a major problem for Spanish students. Spanish were more likely than English students to see language as a problem. UK and Spanish Nursing students are equally enthusiastic about studying or working abroad but UK students have limited language skills, are less able to access Socrates funding for European destinations, and given their age and family commitments, funding is a barrier for 'non-Socrates' destinations.

"Fort Valley State University Cooperative Developmental Energy Program: Broadening the Participation of Underrepresented Minorities in the Geosciences"

According to the American Geological Institute's Status of Recent Geoscience Graduates, 2014, underrepresented minorities (URMs) make up only 7%, 5%, and 2% of graduates at the BS/BA, MA/MS, and Ph.D levels, respectively. Recruiting academically-talented URMs to major in the geosciences instead of majoring in other fields such as medicine, law, business, or engineering is a major undertaking. Numerous factors may contribute as to why few URMs choose geoscience careers. To address the underrepresentation of URMs in the geosciences 1992, the Cooperative Developmental Energy Program (CDEP) of Fort Valley State University (FVSU) and the College of Geosciences at the University of Oklahoma (OU) implemented a 3 + 2 dual degree program specifically in geology and geophysics. Since 1992, FVSU-CDEP has added the University of Texas at Austin (2004), Pennsylvania State University (2005), University of Arkansas (2010), and the University of Nevada at Las Vegas (2015) as partners to offer degrees in geology and geophysics. The dual degree programs consist of students majoring in chemistry or mathematics at FVSU for the first three years and transferring to one of the above partnering universities for years four and five to major in geology or geophysics. Upon completion of the program, students receive a BS degree in chemistry or mathematics from FVSU and a BS degree in geology or geophysics from a partnering university. CDEP has been responsible for recruiting 33 URMs who have earned BS degrees in geology or geophysics. Females constitute 50% of the graduates which is higher than the national average. Also, 56% of these graduates have earned the MS degree and 6% have earned the Ph.D. Currently, 60% of these graduates are employed with oil and gas companies; 20% work for academia; 12% work for governmental agencies; 6 % are professionals with environmental firms; and 2% of the graduate's employment is unknown.

NASA's Space Launch System Transitions From Design To Production

NASA Technical Reports Server (NTRS)

Askins, Bruce R.; Robinson, Kimberly F.

2016-01-01

NASA's Space Launch System (SLS) successfully completed its Critical Design Review (CDR) in 2015, a major milestone on the journey to an unprecedented era of exploration for humanity. CDR formally marked the program's transition from design to production phase just four years after the program's inception and the first such milestone for a human launch vehicle in 40 years. While challenges typical of a complex development program lie ahead, CDR evaluators concluded that the design is technically and programmatically sound and ready to press forward to Design Certification Review (DCR) and readiness for launch of Exploration Mission 1 (EM-1) in the 2018 timeframe. SLS is prudently based on existing propulsion systems, infrastructure and knowledge with a clear, evolutionary path as required by mission needs. In its initial configuration, designated Block 1, SLS will a minimum of 70 metric tons (t) (154,324 pounds) of payload to low Earth orbit (LEO). It will evolve to a 130 t (286,601 pound) payload capacity by upgrading its engines, boosters, and upper stage, dramatically increasing the mass and volume of human and robotic exploration while decreasing mission risk, increasing safety, and simplifying ground and mission operations. CDR was the central programmatic accomplishment among many technical accomplishments that will be described in this paper. The government/industry SLS team successfully test-fired a flight-like five-segment solid rocket motor, as well as seven hotfire development tests of the RS-25 core stage engine. The majority of the major test article and flight barrels, rings, and domes for the core stage liquid oxygen, liquid hydrogen, engine section, intertank, and forward skirt were manufactured at NASA's Michoud Assembly Facility in New Orleans, Louisiana. Renovations to the B-2 test stand for stage green run testing were completed at NASA's Stennis Space Center (SSC), near Bay St. Louis, Mississippi. Core stage test stands are reaching completion at NASA's Marshall Space Flight Center in Huntsville, Alabama. The modified Pegasus barge for core stage transportation from manufacturing to testing and launch sites was delivered to SSC. The Interim Cryogenic Propulsion System test article was also completed. This paper will discuss these and other technical and programmatic successes and challenges over the past year and provide a preview of work ahead before the first flight of this new capability.

Autoimmune blistering diseases (AIBD) are known to negatively impact upon quality of life (QoL); however, there is a paucity of research on the effect of AIBD on work productivity. AIBD can be quite disfiguring in terms of a patient's appearance due to their blistering nature. To determine the impact of AIBD on work productivity and to determine whether patients are stigmatized at work due to their appearance. Sixty-one patients with AIBD completed the Work Productivity and Activity Impairment Questionnaire-Specific Health Problem (WPAIQ-SHP), the Dermatology Life Quality Index (DLQI), the Autoimmune Bullous Disease Quality of Life (ABQOL) and the Treatment of Autoimmune Bullous Disease Quality of Life questionnaires (TABQOL). Non-responders to treatment had more work and activity impairment compared to responders. Worse WPAIQ-SHP scores were correlated with higher ABQOL, TABQOL and DLQI scores. Approximately 14.8% of subjects experienced stigmatization at work due to their appearance. The most common body areas stigmatized were easily visible sites, particularly the hands, arms and feet, with the majority of occurrences related to co-workers; for some patients, this stigmatization occurred on a daily basis. Loss of productivity at work was statistically much higher in those with higher disease severity, ABQOL & TABQOL scores and in non-responders to treatment. Autoimmune blistering diseases negatively impacts upon work productivity and activity. Stigmatization was common in the workplace which leads to increased stress, itself a stimulator of pemphigus. © 2018 European Academy of Dermatology and Venereology.

Workforce and graduate school outcomes of NOAA's Educational Partnership Program

Christenson, T.; Kaplan, M.

2017-12-01

Underrepresented groups, including Black, Hispanic, Native American, Alaska Native, Native Hawaiian and Pacific Island professionals remain underrepresented in STEM fields generally, and in the ocean and atmospheric sciences specifically. NOAA has tried to address this disparity through a number of initiatives under the Educational Partnership Program with Minority Serving Institutions (EPP MSI) which currently has two components: four Cooperative Science Centers (CSCs) aligned with NOAA's mission areas; and an Undergraduate Scholarship Program (USP), both established in 2001. In order to determine the outcomes for the program participants and the impacts of these programs on degree completions and on the workforce, the EPP MSI undertook a multi-pronged effort to identify career and education achievements for 80% of the approximately 1750 EPP MSI alumni, 75% of whom are from underrepresented groups. This was accomplished through 1) searching online resources (e.g. professional web pages, LinkedIn, etc.), 2) personal communication with program-associated faculty, 3) National Student Clearinghouse, 4) a survey of former scholars conducted by Insight Policy Research, and 5) self-reporting though NOAA's Voluntary Alumni Update System. Results show that 60% of CSC alumni currently hold an advanced degree in a STEM field with another 8% currently working toward one. 66% of EPP Undergraduate Scholars go to graduate school. 72% of CSC and USP alumni are currently employed in or pursuing a graduate degree in a NOAA-related* field. More than 70 CSC graduates currently work for NOAA as contractors or federal employees while more than 240 work for other government agencies. More than 400 are employed in the private sector. Of more than 225 PhD graduates, 66 have completed or currently hold post-doctoral positions in NOAA mission fields; 71 have held faculty positions at major universities. However, one challenge is retaining diverse STEM talent within the Geosciences in light of the lure of lucrative jobs in other STEM fields and ensuring robust outcomes beyond degree completions.

Background: This study provides a national profile of major work safety accidents in China, which cause more than 10 fatalities per accident, intended to provide scientific basis for prevention measures and strategies to reduce major work safety accidents and deaths. Methods: Data from 2003–2012 Census of major work safety accidents were collected from State Administration of Work Safety System (SAWS). Published literature and statistical yearbook were also included to implement information. We analyzed the frequency of accidents and deaths, trend, geographic distribution and injury types. Additionally, we discussed the severity and urgency of emergency rescue by types of accidents. Results: A total of 877 major work safety accidents were reported, resulting in 16,795 deaths and 9,183 injuries. The numbers of accidents and deaths, mortality rate and incidence of major accidents have declined in recent years. The mortality rate and incidence was 0.71 and 1.20 per 106 populations in 2012, respectively. Transportation and mining contributed to the highest number of major accidents and deaths. Major aviation and railway accidents caused more casualties per incident, while collapse, machinery, electrical shock accidents and tailing dam accidents were the most severe situation that resulted in bigger proportion of death. Conclusion: Ten years’ major work safety accident data indicate that the frequency of accidents and number of eaths was declined and several safety concerns persist in some segments. PMID:27057515

The objective of the study was recognition of rural women's opinions concerning the degree of heaviness of work activities performed and obtaining the answer to the question: What is the actual level of loading rural women with work? The basic research instrument was a questionnaire form. A representative group of women aged 40-50 were selected for the study because this group had the most complete family structure. The study was conducted among rural women living in the commune of Zwierzyniec. Family size and multi-generationality were analyzed, as well as family members' assistance in household and field activities. The type of work performed was analyzed with consideration of the duration of work and body position while performing this work. Self-reported degree of loading with work on a farm was analyzed, and effective energy expenditure calculated for individual work activities performed by women, based on which the actual degree of loading with work was determined. The respondents generally perceived their loading with work as low. They considered household jobs as not loading with or not exerting any effect on their fatigue and state of health. A very weak statistical relationship was observed between the duration of loading with household jobs and the perceived degree of loading with this work. The Kołmogorov-Smirnov test showed that the evaluations expressed by women concerning the degree of loading with household chores did not depend on time devoted to these work activities. The majority of women similarly evaluated work load, irrespective of the actual degree of loading. Work activities performed in a household were classified according to work load as heavy, medium-heavy and mediocre. Subjective evaluations of work load by rural women considerably differed from the assessment performed using the work time schedule method.

Medical equipment donations in Haiti: flaws in the donation process.

The magnitude 7.0 earthquake that struck Haiti on 12 January 2010 devastated the capital city of Port-au-Prince and the surrounding area. The area's hospitals suffered major structural damage and material losses. Project HOPE sought to rebuild the medical equipment and clinical engineering capacity of the country. A team of clinical engineers from the United States of America and Haiti conducted an inventory and assessment of medical equipment at seven public hospitals affected by the earthquake. The team found that only 28% of the equipment was working properly and in use for patient care; another 28% was working, but lay idle for technical reasons; 30% was not working, but repairable; and 14% was beyond repair. The proportion of equipment in each condition category was similar regardless of whether the equipment was present prior to the earthquake or was donated afterwards. This assessment points out the flaws that existed in the medical equipment donation process and reemphasizes the importance of the factors, as delineated by the World Health Organization more than a decade ago, that constitute a complete medical equipment donation.

Sea Fog Research in the United Kingdom and United States: A Historical Essay Including Outlook.

NASA Astrophysics Data System (ADS)

Lewis, J. M.; Korain, D.; Redmond, K. T.

2004-03-01

A historical review of research on sea fog is presented. The period of interest is essentially the twentieth century, beginning with the celebrated work of G. I. Taylor in the aftermath of the Titanic tragedy. It has been argued that relative maxima in fog frequency over the North Atlantic (including the Brit-ish Isles and the Grand Banks of Newfoundland) and the North Pacific (including the U.S. West Coast) has led to major contributions by scientists in England and the United States. The early work (pre World War II) tended to be phenomenological—that is, conceptual with broad inference from statistical summaries. Yet, this early work laid the foundation for the numerical modeling that came with the advent of computers in the postwar period. The subtleties associated with sea fog formation and maintenance are explored by analyzing some of the results from the numerical simulations. The essay ends with a speculative view on our prospects for a more complete understanding of sea fog in light of the earlier contributions.

They must also have an employee "suitably trained" to administer their program. The National Institute for Occupational Safety and Health and its National Personal Protective Technology Laboratory have worked to champion the occupational health nurse in this role by collaborating with the American Association of Occupational Health Nurses to develop free, online respiratory protection training and resources (RPP Webkit). This article describes the development, content, and success of this training. To date, 724 participants have completed the training, 32.6% of whom lead their organization's respiratory protection program, 15.3% who indicated they will lead a program in the near future, and 52% who did not lead a program, but indicated that the training was relevant to their work. The majority "strongly agreed" the training was applicable to their work and it enhanced their professional expertise. © 2016 The Author(s).

To meet the increasing demand for healthcare providers, it is crucial to recruit and retain more nurse anaesthetists (NAs). The majority of NAs in the Netherlands are >45 years old, and retaining them in their jobs is very important. This study investigates the relationships among burnout, physical health and job satisfaction among Dutch NAs. Two thousand NAs working in Dutch hospitals were invited to participate in this online questionnaire. We tested the relationships among burnout, psychosomatic symptoms, sickness absence, perceived general health and job satisfaction. Nine hundred and twenty-three questionnaires were completed and analysed (46% response rate). Burnout and psychosomatic symptoms were negatively associated with job satisfaction, and predicted 27% of job satisfaction. Perceived general health was positively and sickness absence was negatively related to job satisfaction. Older NAs had a higher incidence of burnout than their younger counterparts. The results confirmed the importance of a healthy psychosocial work environment for promoting job satisfaction. To prevent burnout, further research is necessary to determine the factors causing stress. These findings may also apply to anaesthesiologists who share many tasks and work in close cooperation with NAs.

To map the profile of Brazilian Speech Therapists who report acting in Educational Speech Therapy, with regard to aspects related to training, performance and professional experience. Retrospective study, based on secondary database analysis of the Federal Council of Hearing and Speech Sciences on the questionnaires reporting acting with Educational Environment. 312 questionnaires were completed, of which 93.3% by women aged 30-39 years. Most Speech Therapists continued the studies, opting mostly for specialization. Almost 50% of respondents, have worked for less than six years with the speciality, most significantly in the public service (especially municipal) and private area. The profile of the Speech Therapists active in the Educational area in Brazil is a professional predominantly female, who values to continue their studies after graduation, looking mostly for specialization in the following areas: Audiology and Orofacial Motor. The time experience of the majority is up to 10 years of work whose nature is divided mainly in public (municipal) and private schools. The performance of Speech Therapists in the Educational area concentrates in Elementary and Primary school, with varied workload.

As an undergraduate physics major who spent 2015 deep in a quantum optics lab at Oak Ridge National Laboratory, I knew my 2016 experience with the House of Representatives Energy and Commerce Committee would be a completely new challenge. I have long had a passion for the bridge of communication between the technical and non-technical worlds but it was only through my AIP Mather internship this summer that I was able to see that passion come to life in the realm of science policy. Suddenly, I went from squeezing political philosophy classes into my packed schedule to witnessing the political process first-hand. I was thrilled to find that the skills of critical thinking and communicating complex issues I have developed throughout my training as a physicist were directly applicable to my work in Congress. Overall, my experience this summer has given me insight into the inner workings of the federal policy process, deepened my appreciation for the work of government employees to keep Congressional members informed on the pressing current issues, and exposed me to a whole range of alternative careers within science.

An explanatory model of nurse practitioner job satisfaction.

PubMed

Koelbel, P W; Fuller, S G; Misener, T R

1991-01-01

Job satisfaction influences employee retention, worker productivity, and performance quality. To retain qualified nurse practitioners (NPs), health administrators must identify sources of job satisfaction and dissatisfaction. Herzberg's dual-factor theory of job satisfaction addresses extrinsic and intrinsic work-related factors. Expansion of the model to include global job satisfaction and individual differences provided a broad framework for the assessment of nurse practitioner job satisfaction. The expanded model was used to analyze the job satisfaction of 132 NPs registered with the South Carolina State Board of Nursing in 1988 (final response rate = 90%). Participants completed the Index of Job Satisfaction (IJS), the Minnesota Satisfaction Questionnaire-Short Form (MSQ-SF), and the Personal and Work Background Questionnaire (PWBQ). Although the NPs were moderately satisfied with their overall jobs, extrinsic factors were found to be major sources of dissatisfaction. The optimal combination of variables predicted by regression analysis to influence global job satisfaction were age, number of children, urban locations, achievement, company policies and practices, creativity, independence, and compensation. Implications for health administrators to improve the work environments of NPs are discussed.

Tether deployment monitoring system, phase 2

NASA Technical Reports Server (NTRS)

1989-01-01

An operational Tether Deployment Monitoring System (TEDEMS) was constructed that would show system functionality in a terrestrial environment. The principle function of the TEDEMS system is the launching and attachment of reflective targets onto the tether during its deployment. These targets would be tracked with a radar antenna that was pointed towards the targets by a positioning system. A spring powered launcher for the targets was designed and fabricated. An instrumentation platform and launcher were also developed. These modules are relatively heavy and will influence tether deployment scenarios, unless they are released with a velocity and trajectory closely matching that of the tether. Owing to the tracking range limitations encountered during field trails of the Radar system, final TEDEMS system integration was not completed. The major module not finished was the system control computer. The lack of this device prevented any subsystem testing or field trials to be conducted. Other items only partially complete were the instrumentation platform launcher and modules and the radar target launcher. The work completed and the tests performed suggest that the proposed system continues to be a feasible approach to tether monitoring, although additional effort is still necessary to increase the range at which modules can be detected. The equipment completed and tested, to the extent stated, is available to NASA for use on any future program that requires tether tracking capability.

Burnout has been shown to be present in different health professions, but the prevalence among physiotherapists working in an Arabian setting has not been established. [Purpose] This study aimed to investigate the burnout levels of physiotherapists working in Saudi Arabia and the association of burnout with work and organization-related factors. [Subjects and Methods] A cross-sectional study was conducted at government hospitals in Saudi Arabia. One hundred and nineteen Saudi physiotherapists were included. They electronically completed a questionnaire that included the Maslach Burnout Inventory and the Areas of Worklife Survey. [Results] Participants showed a moderate degree of burnout as reflected by mean scores of the three subscales of the Maslach Burnout Inventory. The majority of participants demonstrated moderate to high burnout levels across the three subscales. A significant association was found between the exhaustion subscale and the subspecialty in which participants worked. A strong association was found between workload and exhaustion subscale scores. [Conclusion] This study was the first to explore burnout and related factors among physiotherapists in an Arabian setting. A moderate degree of burnout and associations of burnout with work and organizational factors were found. The findings may help human resource planning and managing the physiotherapy services.

The majority of women are returning to work full-time after childbirth, and support within their place of employment may influence intention and duration for breastfeeding, but more research is needed. Therefore, the purpose of this study was to explore the influence of employment type on breastfeeding duration upon return to work by examining informal (i.e., verbal encouragement) and direct (i.e., lactation space, flexible time) factors of support. This was a retrospective survey of women's returning-to-work experiences while breastfeeding. Survey contents included respondent demographics as well as questions surrounding perceptions of employer support, work environment, and goal/satisfaction regarding breastfeeding. Data were analyzed via crosstabs and chi-square goodness of fit tests. A total of 1,002 women completed the survey. Significant differences were seen across different employment types. Women within the professional/management industry were most likely to receive informal and direct support for breastfeeding upon return to work. Women within the service industry and production/transportation industry reported receiving the lowest levels of informal and direct support. Workplace support varies by employment type and women in the service and production/transportation industry appear to be at a disadvantage compared with other employment types. There is a need for more breastfeeding support programs to be developed that target specific workplace characteristics.

Future law enforcement officers and social workers: perceptions of domestic violence.

This study compares perceptions of domestic violence for college students planning to work in law enforcement with students aspiring to careers in social work and non-law-enforcement criminal justice (N = 491). The study involves students attending four public universities across one Southern state who completed a survey (spring of 2006) measuring whether various scenarios were (1) related to domestic violence, and (2) worthy of being reported to law enforcement. Findings indicate that all student groups (law enforcement, non-law-enforcement criminal justice, and social work) tended to identify the various scenarios as domestic violence (and worthy of being reported) regardless of the person's sexual orientation, violence severity, and offender's or victim's gender. However, law enforcement students are less sensitive to domestic violence when compared with social work and non-law enforcement criminal justice students. Findings reveal that (1) graduate students, (2) female students, and (3) White students (compared with African American students in general) attending majority White universities were more likely to identify domestic violence and its worthiness of being reported.The data in this study indicate that criminal justice programs produce graduates who are reasonably sensitive toward the importance of appropriate domestic violence response but could still improve using the techniques employed within social work programs.

Project Panther LIFE is an inclusive postsecondary transition program for students with intellectual disabilities providing university access and participation with the primary goal of employment at program completion. Students in the program receive support from their academic mentors and peer coaches during the academic year. This study examines the skills and activities mentors use during their weekly sessions with students with intellectual disabilities and identifies areas in which mentors may require further support or training. Data analysis revealed major themes related to inclusion, self-determination, and adaptive behavior skills. Upon review of the data, we suggest that mentors need ongoing support from transition programs especially in areas related to encouraging self-advocacy and supporting time management.

A phase 2 study has been initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This report covers the second quarter of work. The major accomplishments were: completion of coal liquefaction autoclave reactor runs with Illinois number 6 coal at processing temperatures of 300, 325, and 350 C, and pressures of 1800 psig; analysis of the filter cake and the filtrate obtained from the treated slurry in each run; and correlation of the coal conversions and the liquid yield quality to the surfactant concentration. An increase in coal conversions and upgrading of the liquid product quality due to surfactant addition was observed for all runs.

(Abstract only) This work aims to expand our understanding of the physical characteristics of the Tina asteroid family in the main belt. This small group is unusual, as the only asteroid group currently known to be completely contained in the stable island of one of the principal secular resonances of the main belt, the n6. This family is almost near the center of the main asteroid belt, having its members with a semi-major axis between 2.765 au and 2.807 au. Its largest body is (1222) Tina, 21 km in diameter and an X-type asteroid. We aim to find their taxonomic types by performing correlations with their color indices.

Study of the genetics of speciation--and especially of the genetics of intrinsic postzygotic isolation-has enjoyed remarkable progress over the last 2 decades. Indeed progress has been so rapid that one might be tempted to ask if the genetics of postzygotic isolation is now wrapped up. Here we argue that the genetics of speciation is far from complete. In particular, we review 2 topics where recent work has revealed major surprises: 1) the role of meiotic drive in hybrid sterility and 2) the role of gene transposition in speciation. These surprises, and others like them, suggest that evolutionary biologists may understand less about the genetic basis of speciation than seemed likely a few years ago.

Return to work after treatment completion is important for both cancer survivors and society. Financial distress is one of the factors that may influence the return to work in cancer survivors. However, this relationship has not been well investigated. This study aimed to determine the rate of return to work and its relation to financial distress among Iranian cancer survivors. This descriptive-correlational study was undertaken among 165 cancer survivors who completed their initial treatments and had no signs of active cancer. The Return to Work questionnaire and Financial Distress/Financial Well-Being Scale were used for data collection. Data were analyzed using SPSS statistical software. After initial treatments, 120 cancer survivors (72%) had returned to work, of which 50 patients (42%) had returned to full-time work and 70 (58%) reduced their work hours and returned to part-time work. Cancer survivors also reported high levels of financial distress. In addition, the financial distress was lower among patients who had returned completely to work, in comparison to patients who had quit working for cancer-related reasons (p=0.001) or returned to work as part-time workers (p=0.001). The findings showed that a high percent of Iranian cancer survivors had not returned to their jobs or considerably reduced working hours after treatment completion. Accordingly, due to high levels of financial distress experienced by participants and its relation to return to work, designing rehabilitation programs to facilitate cancer survivor return to work should be considered.

This research aimed to compare the prevalence rates of major depressive disorder (MDD) and to differentiate the presence and severity of depressive symptoms between women and men aged 18-24 years. In this population-based, cross-sectional study (n = 1560), young adults were screened with the Mini International Neuropsychiatric Interview for MDD (n = 137). Participants then completed a self-report questionnaire to gather sociodemographic data, and the presence of each symptom of depression was assessed with the Beck Depression Inventory. The proportion of women (12.2%) with MDD was higher than that of men (5.3%). The symptoms of depression found to be significantly more prevalent in women were sadness, crying, difficulty making decisions, and lack of energy, as well as self-criticism, irritability, changes in self-image, work difficulty, and loss of interest in sex. Sadness and self-criticism were significantly more severe in women than in men. The presentation of depressive symptoms in young adults with MDD differed between men and women.

Failure to conduct periodic fixed-time-to (or scheduled) maintenance on off-highway plant and equipment represents a significant health and safety hazard and major litigation risk for utility contractors completing service excavation and reinstatement works on public highways. Mini-excavators are a ubiquitous mobile plant item used for such tasks and have recently been responsible for several major injuries and fatalities involving workers and members of the public in the United Kingdom (UK). The research utilises the method of triangulation to examine the maintenance practices of utility contractors in the UK. Findings from the research reveal that a combination of prevailing market forces and internal 'company' pressures have inadvertently removed knowledgeable and trained operators, site foremen and managerial supervisors from hands-on maintenance inspections. Rather, 'virtual' maintenance protocols and procedures are adopted by head office but rarely fully implemented on-site. The research concludes with pragmatic recommendations and direction for future research. Copyright © 2015 Elsevier Ltd. All rights reserved.

This report provides a summary of research completed during FY86. Four major research areas are addressed in the work covered by this report: Thermodynamic Research and Analysis addresses the process and system analyses which provide the underlying understanding of physical effects which constitute the energy conversion processes, Experimental Verification and Testing provides confirmation of the analytical projections and empirical relationships, Materials and Structural Research addresses special materials compatibility issues related to operation in the sea. Much of its focus is on concepts for the system CWP which is a major technology cost driver, and Oceanographic, Environmental, and Geotechnical Research addresss those unique design requirements imposed by construction in steep slope coastal areas.

On the Testing of Renovations Inside Historical Opera Houses

Fausti, P.; Prodi, N.

2002-11-01

Due to the large number of historical opera houses in Italy, many theatres have been renovated in the past, but still more will undergo major restoration in the near future. Unfortunately in this context, the quality and protection of acoustics is rarely considered as an issue of its own. As a consequence, the renovations are hardly ever accompanied by proper scientific and technical support. In this paper, the acoustical impact of works inside the Teatro Municipale "R.Valli" in Reggio Emilia, including the restoration of the main hall and the construction of a new acoustic shell, will be dealt with. Surveys were held in the theatre before renovation and were repeated with identical procedure and instruments after its completion. By means of a comparative analysis of the architectural project and of acoustical data, the impact of major changes in the theatre can be predicted. It is shown that this approach can help in drafting an operational scheme for safeguarding the acoustics of historical opera houses.

Helicopter cabin interiors require noise treatment which is expensive and adds weight. The gears inside the main power transmission are major sources of cabin noise. Work conducted by the NASA Lewis Research Center in measuring cabin interior noise and in relating the noise spectrum to the gear vibration of the Army OH-58 helicopter is described. Flight test data indicate that the planetary gear train is a major source of cabin noise and that other low frequency sources are present that could dominate the cabin noise. Companion vibration measurements were made in a transmission test stand, revealing that the single largest contributor to the transmission vibration was the spiral bevel gear mesh. The current understanding of the nature and causes of gear and transmission noise is discussed. It is believed that the kinematical errors of the gear mesh have a strong influence on that noise. The completed NASA/Army sponsored research that applies to transmission noise reduction is summarized. The continuing research program is also reviewed.

We conducted a cross-sectional survey including specialist trainees in obstetrics and gynaecology in the Health Education West Midlands region, UK, to capture their views and assess training opportunities on the use of Kielland's forceps. Half of the trainees in the region completed the survey (87/172, 50%). Only 31% of our trainees worked in units that supported the training on these forceps (27/87, 31%). The majority reported that they did not get enough exposure to using Kielland's forceps (53/87, 60.9%). Only a minority (5.7%, 5/87) felt confident to perform a Kielland's rotational delivery independently. The majority (64.3%, 56/87) were keen to continue using Kielland's forceps in the future if competent. More than two-thirds (86.2%, 75/87) felt that simulation could aid their training. There was large enthusiasm for training on the safe use of Kielland's forceps among trainees in obstetrics and gynaecology in the West Midlands region. A national assessment of training resources is needed to better plan training recourses on this complex skill.

2006-02-01

Microbes construct structurally complex multicellular communities (biofilms) through production of an extracellular matrix. Here we present evidence from scanning electron microscopy showing that a wild strain of the Gram positive bacterium Bacillus subtilis builds such a matrix. Genetic, biochemical and cytological evidence indicates that the matrix is composed predominantly of a protein component, TasA, and an exopolysaccharide component. The absence of TasA or the exopolysaccharide resulted in a residual matrix, while the absence of both components led to complete failure to form complex multicellular communities. Extracellular complementation experiments revealed that a functional matrix can be assembled even when TasA and the exopolysaccharide are produced by different cells, reinforcing the view that the components contribute to matrix formation in an extracellular manner. Having defined the major components of the biofilm matrix and the control of their synthesis by the global regulator SinR, we present a working model for how B. subtilis switches between nomadic and sedentary lifestyles.

My Internship at NASA

Lopez, Isaac

2016-01-01

My name is Isaac Lopez and I am a junior at the University of Houston majoring in Mechanical Engineering Technology. I will be completing my first tour at the NASA-Johnson Space Center ("JSC") as a Mechanical Engineer within the Human Interfaces Branch. Throughout my tour, I was given the opportunity to work on multiple projects that have expanded my knowledge and interest in acoustics and engineering design. One of the projects I worked on at JSC consisted of doing acoustic simulation of the EVA comm. cap. While working on the comm. cap headset, my main duty consisted of simulating the acoustics of the headset to find a solution to the condensing water that can accumulate and block the acoustic tube, causing attenuation or complete loss of audio in one ear for an astronaut using the EVA. For this project, I had to create a Creo model of the comm. cap so that I would be able to import it into Comsol for acoustic simulation. I also had the opportunity to design a portable and lightweight beam degrader for the EEE Parts and Radiation team. With the help of Creo, I was able to make a CAD design and put together a small working prototype for the radiation team to demonstrate the capabilities that the beam degrader had. In addition to these projects, JSC allowed me to work closely on projects with other interns. I had the opportunity to help another intern with his acoustic diverter, intended to improve the sound quality in Node 1 of the ISS. During this project, I helped with some of the acoustic testing inside the anechoic chamber as well as helping record data during testing at the ISS mock up. During the course of my first tour, I was able to learn and continually improve on my CAD drafting skills. With each project I worked on, I acquired new ways to create and improve various designs with various constraints. Furthermore, I also had the opportunity to work with electrical engineers and learn about the electronic components that would provide control of the beam degrader functions. I was able to take the knowledge, skills and designs I had acquired during my tour at JSC (such as Finite Element Analysis) and apply them to my work on the Comsol Multiphysics software for acoustics simulation. I was also able to use it to do some stress analysis on a proposed design for a proposed Habitat structure. My time at JSC has been invaluable as it helped me grow and more fully-comprehend my major as well as spark an interest in acoustics and how much it relates to mechanical engineering. This internship has taught me that engineering is much more than a profession - it is embedded in our daily lives as a puzzle that requires critical thinking as an everyday challenge that makes life more interesting.

On 30 September 2016, Rosetta completed its incredible mission by landing on the surface of Comet 67P/Churyumov-Gerasimenko. Although this marked an end to the spacecraft's active operations, intensive work is still ongoing with instrument teams preparing their final science data deliveries for ingestion into ESA's Planetary Science Archive (PSA). In addition, ESA is establishing contracts with some instrument teams to enhance their data and documentation in an effort to provide the best long-term archive possible for the Rosetta mission. Currently, the majority of teams have delivered all of their data from the nominal mission (end of 2015), and are working on their remaining increments from the 1-year mission extension. The aim is to complete the nominal archiving with data from the complete mission by the end of this year, when a full mission archive review will be held. This review will assess the complete data holdings from Rosetta and ensure that the archive is ready for the long-term. With the resources from the operational mission coming to an end, ESA has established a number of 'enhanced archiving' contracts to ensure that the best possible data are delivered to the archive before instrument teams disband. Updates are focused on key aspects of an instrument's calibration or the production of higher level data / information, and are therefore specific to each instrument's needs. These contracts are currently being kicked off, and will run for various lengths depending upon the activities to be undertaken. The full 'archive enhancement' process will run until September 2019, when the post operations activities for Rosetta will end. Within these contracts, most instrument teams will work on providing a Science User Guide for their data, as well as updating calibrations. Several teams will also be delivering higher level and derived products. For example, the VIRTIS team will be updating both their spectral and geometrical calibrations, and will aim to deliver mapping products to the final archive. Similarly, the OSIRIS team will be improving their calibrations and delivering data additionally in FITS format. The Rosetta Plasma Consortium (RPC) instruments will complete cross-calibrations and a number of activities individual to each instrument. The MIDAS team will also be working on cross-calibrations and will produce a dust particle catalog from the comet coma. GIADA will be producing dust environment maps, with products in 3D plus time. A contract also exists to produce and deliver data set(s) containing sup-porting ground-based observations from amateur astronomers. In addition to these contracts, the Rosetta ESA archiving team will produce calibrated data sets for the NAVCAM instrument, and will work to include the latest shape models from the comet into the final Rosetta archive. Work is also underway to provide a centralized solution to the problem of geometry on the comet. This presentation will outline the current status of the Rosetta archive, as well as highlighting some of the 'enhanced archiving' activities planned with the various instrument teams on Rosetta.

By 2020, depression is projected to be among the most important contributors to the global burden of disease. A plethora of data confirms that despite the availability of effective therapies, major depressive disorder continues to exact an enormous toll; this, in part, is due to difficulties reaching complete remission, as well as the specific associated costs of both the disorder's morbidity and mortality. The negative effects of depression include those on patients' occupational functioning, including absenteeism, presenteeism, and reduced opportunities for educational and work success. The use of management algorithms has been shown to improve treatment outcomes in major depressive disorder and may be less costly than "usual care" practices. Nevertheless, many patients with depression remain untreated. As well, even those who are treated often continue to experience suboptimal quality of life. As such, the treatment algorithms in this article may improve outcomes for patients suffering with depression. This paper introduces some of the principal reasons underlying these treatment gaps and examines measures or recommendations that might be changed or strengthened in future practice guidelines to bridge them.

2011-12-01

Central America experienced extensive expansion of agricultural land during development of the major Central American societies, followed by widespread abandonment and regrowth of natural vegetation after the European conquest. Here we use a high resolution climate model, in combination with a new land cover reconstruction, to investigate the impact of pre- (1490 C.E.) and post- (1650 C.E.) Columbian land cover change on climate in this region. Pre-Columbian land cover causes significant precipitation reductions over coastal Mexico, the Yucatan, and southern Mexico during the wet season, as replacement of forests with agricultural land reduces evapotranspiration fluxes to the atmosphere. Conversely, precipitation over the Yucatan increases during the dry season, as increased surface warming moves additional moisture into this region from the surrounding oceans. With the post-Columbian period, during which major population declines led to large scale agricultural abandonment, the forest recovery results in a partial, though not complete, return to wetter conditions. Our study finds support for previous work speculating that land cover change associated with the Mayan civilizations may have amplified major droughts in the region, and points to the possibility of a direct biogeophysical response to the forest recovery following the arrival of Europeans.

To examine nurse leaders' change management projects within British Columbia, Canada. British Columbia Nursing Leadership Institute 2007-10 attendees worked on year-long change management initiatives/projects of importance to their respective health-care institutions. Most leaders were in first-line positions with <3 years' experience. Consenting leaders' project reports (N = 133) were content analysed for specific themes: types of projects; scope of projects (e.g. unit or local level, departmental, institutional); influence targets or key stakeholder groups targeted by the projects; leadership successes and challenges. Of study participants, 77% successfully completed their projects. Staff tool and resource development and existing services improvement were major project types. Care delivery teams were the major influence targets. Only 25% of projects were at the unit level. Many projects had broader scopes, such as institutional levels. Participants cited multiple leadership successes, including enhanced leadership styles and organizational skills. First-line nurse leaders were able to successfully manage projects beyond their traditional scope of responsibilities. The majority of projects dealt with staff needs and healthcare restructuring initiatives. Constant change is a global reality. Change management, a universal competency, must be included in leadership development programmes. © 2011 Blackwell Publishing Ltd.

Chemical-Sensing Cables Detect Potential Threats

NASA Technical Reports Server (NTRS)

2007-01-01

Intelligent Optical Systems Inc. (IOS) completed Phase I and II Small Business Innovation Research (SBIR) contracts with NASA's Langley Research Center to develop moisture- and pH-sensitive sensors to detect corrosion or pre-corrosive conditions, warning of potentially dangerous conditions before significant structural damage occurs. This new type of sensor uses a specially manufactured optical fiber whose entire length is chemically sensitive, changing color in response to contact with its target, and demonstrated to detect potentially corrosive moisture incursions to within 2 cm. After completing the work with NASA, the company received a Defense Advanced Research Projects Agency (DARPA) Phase III SBIR to develop the sensors further for detecting chemical warfare agents, for which they proved just as successful. The company then worked with the U.S. Department of Defense (DoD) to fine tune the sensors for detecting potential threats, such as toxic industrial compounds and nerve agents. In addition to the work with government agencies, Intelligent Optical Systems has sold the chemically sensitive fiber optic cables to major automotive and aerospace companies, who are finding a variety of uses for the devices. Marketed under the brand name Distributed Intrinsic Chemical Agent Sensing and Transmission (DICAST), these unique continuous-cable fiber optic chemical sensors can serve in a variety of applications: Corrosive-condition monitoring, aiding experimentation with nontraditional power sources, as an economical means of detecting chemical release in large facilities, as an inexpensive "alarm" systems to alert the user to a change in the chemical environment anywhere along the cable, or in distance-resolved optical time domain reflectometry systems to provide detailed profiles of chemical concentration versus length.

Research training of Developmental-Behavioral Pediatrics fellows: a survey of fellowship directors by Developmental-Behavioral Pediatrics Research Network.

To describe research training in Developmental-Behavioral Pediatrics (DBP) Fellowship Programs. Thirty-five US-accredited DBP fellowships were contacted through the Developmental-Behavioral Pediatrics Research Network to complete an online survey on scholarly work and research training. With an 83% response rate, responding programs represented 110 (87 filled) fellowship positions. External funding for fellowship positions was minimal (11 positions fully funded, 13 funded above 50% of cost). Structured research training included didactic lectures, web-based training, university courses, direct mentoring, journal clubs, and required reading. Of the 159 fellows described, spanning a 5-year training period, the majority chose projects relying on their own data collection (57%) rather than joining an existing research study and focused on clinical research (86%). Among 96 fellows with completed scholarly work, 29% were observational/epidemiological studies, 22% secondary analyses of large data sets, 16% community-based research, and 15% survey design. A limited number of fellows pursued basic science, meta-analysis/critical appraisal of the literature, or analysis of public policy. Barriers to successful fellow research are as follows: lack of time and money, challenges in balancing clinical demands and protected faculty research time, limited faculty research opportunities, time or expertise, and a lack of infrastructure for fellow research mentoring. The scholarly work of fellows in DBP fellowship programs has primarily focused on clinical research using observational/epidemiological research and secondary analysis of large data set. Barriers largely in faculty time and expertise for research mentoring and inadequate funding in programs that have high clinical demands and little resources for research efforts were noted.

To examine students' beliefs, behaviours and attitudes in relation to interprofessional socialisation, and their expectations and experience, before and after a two-week clinical placement in ambulatory care. Interprofessional clinical placements for students are important for developing an understanding of interprofessional collaboration and identity, for the benefit of patient care. Ambulatory care environment involves collaborative management of complex chronic problems. This educator supported placement enabled final year nursing and medical students to work together. A descriptive matched pre-post study was conducted. Students' completed an online questionnaire pre and post their clinical placement. The questionnaire comprised of three sections; demographic information, the Interprofessional Socialisation and Valuing Scale and open-ended questions. Descriptive analysis and paired t-tests were conducted for the three subscales and thematic analysis of qualitative responses was conducted. Sixty-two of the 151 students between 2011-2014 completed both surveys. There was a significant increase post placement in the overall Interprofessional Socialisation and Valuing Scale scores. The change was greater for nursing students compared with medical students, although for both groups the change was small. The majority had a good to very good experience learning each other's and their own professions, and identified the Nurse Educator and Teaching Registrar as key to success. A clinical placement in an ambulatory setting for nursing and medical students resulted in an increase in self-perceived ability to work with others and in valuing working with others. Interprofessional clinical placements are essential for students to understand interprofessional practice for better patient outcomes and developing their own perspective of future work within an interprofessional team. Ambulatory care is an ideal environment for nursing and other health professional students to engage in interprofessional clinical placements. This article is protected by copyright.

Controlling collective dynamics in complex minority-game resource-allocation systems

NASA Astrophysics Data System (ADS)

Zhang, Ji-Qiang; Huang, Zi-Gang; Dong, Jia-Qi; Huang, Liang; Lai, Ying-Cheng

2013-05-01

Resource allocation takes place in various kinds of real-world complex systems, such as traffic systems, social services institutions or organizations, or even ecosystems. The fundamental principle underlying complex resource-allocation dynamics is Boolean interactions associated with minority games, as resources are generally limited and agents tend to choose the least used resource based on available information. A common but harmful dynamical behavior in resource-allocation systems is herding, where there are time intervals during which a large majority of the agents compete for a few resources, leaving many other resources unused. Accompanying the herd behavior is thus strong fluctuations with time in the number of resources being used. In this paper, we articulate and establish that an intuitive control strategy, namely pinning control, is effective at harnessing the herding dynamics. In particular, by fixing the choices of resources for a few agents while leaving the majority of the agents free, herding can be eliminated completely. Our investigation is systematic in that we consider random and targeted pinning and a variety of network topologies, and we carry out a comprehensive analysis in the framework of mean-field theory to understand the working of control. The basic philosophy is then that, when a few agents waive their freedom to choose resources by receiving sufficient incentives, the majority of the agents benefit in that they will make fair, efficient, and effective use of the available resources. Our work represents a basic and general framework to address the fundamental issue of fluctuations in complex dynamical systems with significant applications to social, economical, and political systems.

Depressive symptoms, satisfaction with health care, and 2-year work outcomes in an employed population.

Druss, B G; Schlesinger, M; Allen, H M

2001-05-01

The relationship of depressive symptoms, satisfaction with health care, and 2-year work outcomes was examined in a national cohort of employees. A total of 6,239 employees of three corporations completed surveys on health and satisfaction with health care in 1993 and 1995. This study used bivariate and multivariate analyses to examine the relationships of depressive symptoms (a score below 43 on the Medical Outcomes Study Short-Form Health Survey mental component summary), satisfaction with a variety of dimensions of health care in 1993, and work outcomes (sick days and decreased effectiveness in the workplace) in 1995. The odds of missed work due to health problems in 1995 were twice as high for employees with depressive symptoms in both 1993 and 1995 as for those without depressive symptoms in either year. The odds of decreased effectiveness at work in 1995 was seven times as high. Among individuals with depressive symptoms in 1993, a report of one or more problems with clinical care in 1993 predicted a 34% increase in the odds of persistent depressive symptoms and a 66% increased odds of decreased effectiveness at work in 1995. There was a weaker association between problems with plan administration and outcomes. Depressive disorders in the workplace persist over time and have a major effect on work performance, most notably on "presenteeism," or reduced effectiveness in the workplace. The study's findings suggest a potentially important link between consumers' perceptions of clinical care and work outcomes in this population.

Prediction of working memory performance in schizophrenia by plasma ratio of clozapine to N-desmethylclozapine.

Clozapine's potent antagonism of muscarinic M1 receptors is thought to worsen working memory deficits associated with schizophrenia. In contrast, its major metabolite, N-desmethylclozapine (NDMC), is thought to enhance working memory via its M1 receptor agonist activity. The authors hypothesized that the ratio of serum clozapine and NDMC concentrations would be inversely associated with working memory performance in schizophrenia. Thirty patients with schizophrenia or schizoaffective disorder who were receiving clozapine monotherapy at bedtime completed the MATRICS Consensus Cognitive Battery (MCCB) on the day their blood was collected to assess concentrations of clozapine and NDMC as well as serum anticholinergic activity. The clozapine/NDMC ratio was significantly and negatively associated with working memory performance after controlling for age, gender, education, and symptom severity. No significant associations were found between individual clozapine and NDMC concentrations and working memory performance. Serum anticholinergic activity was significantly associated with clozapine concentration, but not with working memory performance or NDMC concentration. No significant associations were found between any pharmacological measure and performance on other MCCB cognitive domains. This hypothesis-driven study confirms that clozapine/NDMC ratio is a strong predictor of working memory performance in patients with schizophrenia. This finding suggests that manipulating the clozapine/NDMC ratio could enhance cognition in patients with schizophrenia treated with clozapine. It also supports the study of procholinergic agents, such as M1 receptor-positive allosteric modulators, to enhance cognition in schizophrenia.

Several studies highlighting a correlation between call-center working conditions and psychosocial and ergonomic hazards. The aim of this study is to provide an operating methodology for the risk assessment of work-related stress. The study involved 554 call-centre workers employed in three insurance organizations and a mixed work group (worker, company and public health representative) for the study management was defined. We experimented an objective self-made checklist and then we administered a modified version of the OSI (Occupational Stress Indicator) questionnaire. We obtained complementary information from the two different data collection methods. The findings highlight a low level of perceived stress and health complaints compared with other studies previously carried out mainly in 'outsourcing' call centres: workers don't show stress symptoms without adopting coping strategies. Moreover the study underlines an acceptable level of work satisfaction, although there are low career opportunities. These results are probable due to the low job seniority associated to the high job security--the large majority of respondents, 87%, consisted of permanent workers--and the working time mainly consisted of daily shifts five days a week. Our methodology seems to be able to detect the level of work-related stress with a good degree of coherence. Furthermore the presence of a mixed work group determined a good level of involvement among the workers: 464 out of 554 operators completed and returned the questionnaire, representing a response rate of about 84%.

Uganda has an acute problem of inadequate human resources partly due to health professionals' unwillingness to work in a rural environment. One strategy to address this problem is to arrange health professional training in rural environments through community placements. Makerere University College of Health Sciences changed training of medical students from the traditional curriculum to a problem-based learning (PBL) curriculum in 2003. This curriculum is based on the SPICES model (student-centered, problem-based, integrated, community-based and services oriented). During their first academic year, students undergo orientation on key areas of community-based education, after which they are sent in interdisciplinary teams for community placements. The objective was to assess first year students' perceptions on experiential training through community placements and factors that might influence their willingness to work in rural health facilities after completion of their training. The survey was conducted among 107 newly admitted first year students on the medical, nursing, pharmacy and medical radiography program students, using in-depth interview and open-ended self-administered questionnaires on their first day at the college, from October 28-30, 2008. Data was collected on socio-demographic characteristics, motivation for choosing a medical career, prior exposure to rural health facilities, willingness to have part of their training in rural areas and factors that would influence the decision to work in rural areas. Over 75% completed their high school from urban areas. The majority had minimal exposure to rural health facilities, yet this is where most of them will eventually have to work. Over 75% of the newly admitted students were willing to have their training from a rural area. Perceived factors that might influence retention in rural areas include the local context of work environment, support from family and friends, availability of continuing professional training for career development and support of co-workers and the community. Many first year students at Makerere University have limited exposure to health facilities in rural areas and have concerns about eventually working there.

2015-09-01

Neoadjuvant systemic therapy is being used increasingly in the treatment of early-stage breast cancer. Response, in the form of pathological complete response, is a validated and evaluable surrogate end point of survival after neoadjuvant therapy. Thus, pathological complete response has become a primary end point for clinical trials. However, there is a current lack of uniformity in the definition of pathological complete response. A review of standard operating procedures used by 28 major neoadjuvant breast cancer trials and/or 25 sites involved in such trials identified marked variability in specimen handling and histologic reporting. An international working group was convened to develop practical recommendations for the pathologic assessment of residual disease in neoadjuvant clinical trials of breast cancer and information expected from pathology reports. Systematic sampling of areas identified by informed mapping of the specimen and close correlation with radiological findings is preferable to overly exhaustive sampling, and permits taking tissue samples for translational research. Controversial areas are discussed, including measurement of lesion size, reporting of lymphovascular space invasion and the presence of isolated tumor cells in lymph nodes after neoadjuvant therapy, and retesting of markers after treatment. If there has been a pathological complete response, this must be clearly stated, and the presence/absence of residual ductal carcinoma in situ must be described. When there is residual invasive carcinoma, a comment must be made as to the presence/absence of chemotherapy effect in the breast and lymph nodes. The Residual Cancer Burden is the preferred method for quantifying residual disease in neoadjuvant clinical trials in breast cancer; other methods can be included per trial protocols and regional preference. Posttreatment tumor staging using the Tumor-Node-Metastasis system should be included. These recommendations for standardized pathological evaluation and reporting of neoadjuvant breast cancer specimens should improve prognostication for individual patients and allow comparison of treatment outcomes within and across clinical trials.

Short communication: Characteristics of student success in an undergraduate physiology and anatomy course.

2014-10-01

Several factors affect the success of students in college classes. The objective of this research was to determine what factors affect success of undergraduate students in an anatomy and physiology class. Data were collected from 602 students enrolled in the Agriculture and Life Sciences (ALS) 2304 Animal Physiology and Anatomy course from 2005 through 2012. The data set included 476 females (79.1%) and 126 males (20.9%). Time to complete exams was recorded for each student. For statistical analyses, students' majors were animal and poultry sciences (APSC), agricultural sciences, biochemistry, biological sciences, dairy science, and "other," which combined all other majors. All analyses were completed using the GLIMMIX procedure of SAS (SAS Institute Inc., Cary, NC). Gender, major, matriculation year, major by year interaction, gender by year interaction, and time to complete the exam affected final course grade. The significant gender effect was manifested in the final grade percentage of 75.9 ± 0.4 for female students compared with 72.3 ± 0.6 for male students. Junior males had final course grades comparable with those of females, but sophomore and senior males had lower final course grades than other combinations. Biology majors had a final grade of 82.4 ± 0.6 and this grade was greater than all other majors. Students classified as "other" had a final score of 74.4 ± 0.8, which was greater than agricultural science majors (69.5 ± 0.9). The APSC grade (72.6 ± 0.5) was higher than the agricultural science majors. Junior students had significantly greater final grades (76.1 ± 0.5) than sophomores (73.3 ± 0.6) and seniors (72.9 ± 0.9). All biology students had greater final grades than all other majors, but biochemistry juniors had greater final course grades than APSC, agricultural science, and dairy science juniors. "Other" seniors had greater final course grades than agricultural science seniors. The regression for time to complete the exam was curvilinear and suggests that highest exam scores were at about 90-min completion time. It may be that some male students need better preparation for anatomy and physiology and their educational preparation should mimic that of female students more in terms of advance-placement biology in high school. These results suggest that biology majors might be better prepared for animal anatomy and physiology than other students. Copyright © 2014 American Dairy Science Association.

Can you see me? Experiences of nurses working night shift in Australian regional hospitals: a qualitative case study.

Powell, Idona

2013-10-01

To report a study that explored the experiences of night-shift nurses, focusing on employee interrelationships and work satisfaction. Night-shift nurses are a critical component in hospital care making it essential to understand the experiences that give meaning to their work and understand how these nurses and the organization can benefit from their contribution to hospital care. A literature review revealed minimal research in this area. Qualitative case study. A qualitative case study using semi-structured interviews and self-completed diaries was conducted in 2010 in regional public hospitals in Australia. Participants were 14 nurses working nights half or more of their shifts in medical or surgical wards. Thematic analysis identified four major areas of concern: work relationships, work environment, work practices and lifestyle impact. Notably, work relationships were most meaningful for nurses on the same shift; night-shift nurses experienced working conditions inferior to their daytime counterparts including a perception of minimal leadership. Despite limited education opportunities, night shift provided opportunity for professional growth for some nurses with a slippage in skills for others; night shift provided flexibility for family and social activities, yet impeded these same activities, primarily due to pervasive fatigue. Night-shift nurses considered their role critical, yet believed that they were poorly regarded. The strong interpersonal relationships developed between night-shift workers need to be capitalized on whilst developing a more effective leadership model, improved work environment, more equitable professional development, and genuine recognition of the critical role of night nurses. © 2013 Blackwell Publishing Ltd.

NASA's Space Launch Transitions: From Design to Production

2016-01-01

NASA's Space Launch System (SLS) successfully completed its Critical Design Review (CDR) in 2015, a major milestone on the journey to an unprecedented era of exploration for humanity. CDR formally marked the program's transition from design to production phase just four years after the program's inception and the first such milestone for a human launch vehicle in 40 years. While challenges typical of a complex development program lie ahead, CDR evaluators concluded that the design is technically and programmatically sound and ready to press forward to Design Certification Review (DCR) and readiness for launch of Exploration Mission 1 (EM-1) in the 2018 timeframe. SLS is prudently based on existing propulsion systems, infrastructure and knowledge with a clear, evolutionary path as required by mission needs. In its initial configuration, designated Block I, SLS will a minimum of 70 metric tons (t) of payload to low Earth orbit (LEO). It can evolve to a 130 t payload capacity by upgrading its engines, boosters, and upper stage, dramatically increasing the mass and volume of human and robotic exploration while decreasing mission risk, increasing safety, and simplifying ground and mission operations. CDR was the central programmatic accomplishment among many technical accomplishments that will be described in this paper. The government/industry SLS team successfully test fired a flight-like five-segment solid rocket motor, as well as seven hotfire development tests of the RS-25 core stage engine. The majority of the major test article and flight barrels, rings, and domes for the core stage liquid oxygen, liquid hydrogen, engine section, intertank, and forward skirt were manufactured at NASA's Michoud Assembly Facility. Renovations to the B-2 test stand for stage green run testing were completed at NASA Stennis Space Center. Core stage test stands are rising at NASA Marshall Space Flight Center. The modified Pegasus barge for core stage transportation from manufacturing to testing and launch sites was delivered. The Interim Cryogenic Propulsion System test article was also completed. This paper will discuss these and other technical and programmatic successes and challenges over the past year and provide a preview of work ahead before the first flight of this new capability.

2011-01-01

Many research studies have focused on perceptions of stuttering by various groups of people. However, there is limited research on the perceptions of university instructors toward stuttering and people who stutter. Therefore, this study explored the perceptions of university instructors toward stuttering and students who stutter, and their beliefs about classroom participation. Participants included 328 university instructors across a variety of disciplines at two Midwestern universities. Each participant completed a 12-item questionnaire regarding perceptions related to stuttering, students who stutter, and classroom participation. Of the 328 participants, 212 completed an open-ended question about their experiences and concerns of working with students who stutter. Results indicated that increased knowledge of stuttering is associated with positive attitudes toward students who stutter. Moreover, the participants in this study expressed a need for more information about stuttering and ways to accommodate students who stutter in the classroom. After reading this article, the reader will be able to: (1) discuss the challenges that university instructors face when working with students with disabilities; (2) provide a rationale for the need to explore the perceptions of university instructors toward students who stutter; (3) describe the major themes of university instructors' knowledge of stuttering, and beliefs about classroom participation for students who stutter; and (4) discuss the need for disseminating more knowledge about stuttering to university instructors.

The Outreach Project was initiated in October 1994 with the objective of developing a multi-year plan for the U.S. Department of Energy (DOE) for targeted outreach activities for stakeholders in industry and the general public. This status report summarizes the work on industry outreach that has been completed since the inception of the project in October 1994. A three-pronged approach was taken to ascertain issues related to industry outreach. First, there was a review of on-going and past industry outreach activities at DOE and NHA. Next, a series of meetings with industry decision makers was arranged to get a bettermore » understanding of industry interests and concerns, and to discuss how DOE and industry could work collaboratively to develop hydrogen energy systems. Third, a workshop is scheduled where representatives from industry, DOE and other federal agencies can identify issues that would enhance partnering between the federal government and industry in the development of hydrogen energy systems. At this tiny, the review of on-going and past activities has been completed. Industry interviews are in progress and a majority of meetings have been held. Analysis of the information gained is in progress. The preliminary analysis of this information indicates that for appropriate near-term demonstration-type projects, the level of interest for collaboration between DOE and industry is high. The data also identifies issues industry is concerned with which impact the commercialization of hydrogen energy systems.« less

A layout of a reduced-height 630A assembly (34 to 23 ft) was prepared and is presently being evaluated for use in a merchant vessel. While shielding studies indicate the need for some rearrangement of the shield materials, the desired radiation constraint can be obtained without an increase in shielding weight. A preliminary stress analysis of the pressure vessel, flow path analysis, and insulation evaluation was completed and showed no major problems. Evaluation of the total containment design indicates a design pressure of 45 psig. The Critical Experiment (CE) mockup is about 80% complete. The CE tank and dolly is aboutmore » 50% complete. The CE hazards report was reviewed and approved. The draft of the test program and procedures document is 75% complete. The LPT control room modifications were made, and the draft of the standard operating procedures completed. The CE fuel was inspected and a significant portion was found to be of no use, about 60% requires recoating. Creep and oxidation test time on some of the fuel sheet has exceeded 3000 hr with no significant oxidation or elongation on any of the samples. The nickel -chromium alloy sheet high- temperature (1750 F) stress and oxidating testing have exceeded 5000 hr with elongations below 0.8% except for one sample of 2.3%. Experimental fuel sheet samples were prepared and comparative property studies were ini-tiated. Fabrication of the ring test assembly, 3-F-1, for test in the MTR is essentially complete. The design of the test ring for seal evaluations was initiated. A detailed schedule for the work in FY 63 was prepared and issued for comments and concurrence. (auth)« less

Epidemiology, co-morbidity, and impact on health-related quality of life of self-reported headache and musculoskeletal pain--a gender perspective.

Headache and musculo-skeletal pain are major public health problems. Substantial proportions of the general population report that they experience pain problems that affect their work, daily living and social life. Epidemiological studies have consistently shown that the prevalence of most pain conditions is higher in women than in men. Cross-sectional survey in the county of Uppland, Sweden, 1995. Five thousand four hundred and four completed the questionnaire (response rate=68%). In these analyses for persons aged 20-64 years 4506 were included. Back pain (22.7%) and shoulder pain (21.0%) were the most commonly reported medical problems in the population with pain in arms/legs (15.7%) in fifth and headache (12.5%) in eight place. Major gender differences were found. The prevalence of pain conditions, especially headache, was higher among women. Women reported more severe pain. Co-morbidity between pain conditions and psychiatric and somatic problems was higher among women. Health-related quality of life (SF-36) differed by gender and type of pain condition. The physical dimensions of HRQoL were more affected by headache among men; psychological dimensions were more affected among women. Among both men and women, pain conditions were associated with poorer socioeconomic conditions and life-style factors but there were gender differences. Education and unemployment were important only among men while economical difficulties, half-time work and being married were associated with pain among women. Obesity, early disability retirement, long time sick-leave and lack of exercise were associated with pain conditions generally. Factors associated with pain conditions were unevenly distributed between genders. There are major differences between men and women in the prevalence and severity of self-reported pain in the population. Biological factors may explain some of the differences but the main explanation is presumably gender disparities in work, economy, daily living, social life and expectations between women and men. Although improved working conditions are of importance, deeper societal changes are needed to reduce the inequities in pain experiences between women and men.

The United States Geological Survey (USGS) and the General Directorate of Mineral Research and Exploration in Turkey (Maden Tetkik ve Arama:MTA) are working together to provide a more complete understanding of the chemical properties of lignites from major Turkish lignite producing areas. The project is a part of the USGS effort to produce an international coal database and is part of the ``Technological and Chemical properties of Turkish Lignite Inventory Project'' being conducted by the MTA General Directorate. The lignites in Turkey formed in several different depositional environments at different geologic times and have differing chemical properties. The Eocene lignitesmore » are limited to northern Turkey. Oligocene lignites, in the Trace Basin of northwestern Turkey, are intercalated with marine sediments. Miocene lignites are generally located in western Turkey. These coal deposits have relatively abundant reserves, with limnic characteristics. The Pliocene-Pleistocene lignites are found in the eastern part of Turkey. Most of these lignites have low calorific values, high moisture and high ash contents. The majority of the lignite extraction is worked in open-pit mines. Turkish lignite production is used mainly by power plants; small amounts are used by households and in industry. All the samples in this study were collected as channel samples of the beds. Analyses of 71 coal samples (mostly lignites) have been completed for 54 elements using various analytical techniques including inductively coupled plasma emission and mass spectrometry, instrumental neutron activation analysis and various single element techniques. Many of these lignites have elemental concentrations similar to those of US lignites. However, maximum or mean concentrations of B, Cr, Cs, Ni, As, Br, Sb, Cs and U in Turkey were higher than the corresponding maximum or mean found in either of the Fort Union or Gulf Coast basins, the two most productive lignite basins in the U.S.« less

Spatial Thinking in Atmospheric Science Education

Atmospheric science is a STEM discipline that involves the visualization of three-dimensional processes from two-dimensional maps, interpretation of computer-generated graphics and hand plotting of isopleths. Thus, atmospheric science draws heavily upon spatial thinking. Research has shown that spatial thinking ability can be a predictor of early success in STEM disciplines and substantial evidence demonstrates that spatial thinking ability is improved through various interventions. Therefore, identification of the spatial thinking skills and cognitive processes used in atmospheric science is the first step toward development of instructional strategies that target these skills and scaffold the learning of students in atmospheric science courses. A pilot study of expert and novice meteorologists identified mental animation and disembedding as key spatial skills used in the interpretation of multiple weather charts and images. Using this as a starting point, we investigated how these spatial skills, together with expertise, domain specific knowledge, and working memory capacity affect the ability to produce an accurate forecast. Participants completed a meteorology concept inventory, experience questionnaire and psychometric tests of spatial thinking ability and working memory capacity prior to completing a forecasting task. A quantitative analysis of the collected data investigated the effect of the predictor variables on the outcome task. A think-aloud protocol with individual participants provided a qualitative look at processes such as task decomposition, rule-based reasoning and the formation of mental models in an attempt to understand how individuals process this complex data and describe outcomes of particular meteorological scenarios. With our preliminary results we aim to inform atmospheric science education from a cognitive science perspective. The results point to a need to collaborate with the atmospheric science community broadly, such that multiple educational pipelines are affected including university meteorology courses for majors and non-majors, military weather forecaster preparation and professional training for operational meteorologists, thus improving student learning and the continued development of the current and future workforce.

Educationalists and managers internationally are challenged to find ways of preparing, recruiting early in their careers, and retaining nurses into public health roles in primary care. Public health nursing qualifications are post-initial nurse registration in the United Kingdom as in some other countries. In the mid twentieth century there were a number of innovative programmes of dual qualification: registered nurse and health visitor (the United Kingdom term for public health nurse). To investigate the career histories of graduates from courses integrating both nursing and health visitor qualifications. An observational, survey study. The United Kingdom. A purposive sample of graduates from integrated registered nurse and health visitor programmes, 1959-1995, from one University. Self completed, anonymous, survey sent to graduates, with contact details known to the University and through snowballing techniques, in 2011. Forty five women (56%), graduates in all four decades, returned the survey. A significant majority (82%) had taken up health visitor posts on completing the course. Over their careers, 42% of all jobs held were as health visitors. Only four never worked in a post that required a health visiting qualification. Most had undertaken paid work throughout their careers that focused on aspects of public health, often linked to child, maternal and/or family wellbeing. Many held teaching/lecturing and management posts at some point in their career. Those holding management posts were more likely to report leaving them as a result of organisational re-structuring or redundancy than those in non-management posts. Courses that prepare students to be both nurses and health visitors result in a majority of graduates who take up posts as health visitors on qualification and subsequently. Nurse education planners may find this evidence of value in determining ways of providing a future workforce for public health nursing. Copyright © 2012 Elsevier Ltd. All rights reserved.

Interaction between physicians and pharmaceutical sales representative (PR) is a major component of the promotional activities by pharmaceutical companies. The lack of studies examining the magnitude of this interaction in Saudi Arabia is evident. The objective of this study is to estimate the magnitude and associated characteristics of physician-PR interaction. A cross-sectional study was conducted among physicians working in the different regions of Saudi Arabia between March and July of 2012. A cross-sectional study was undertaken between March and July of 2012 in the different regions of Saudi Arabia. A self-administrated questionnaire was developed and handed to all participants, both in paper and electronic formats. A total of 663 participants completed the questionnaire. The participation rate was 66.3% (663/1000). The majority of the participants (72.9%) reported interaction with PRs. This was lower among residents/interns compared to higher ranking employees (55.6% vs 83.6%, P < .001). Approximately half (48.3%) of the interactions occurred at a rate of more than once a month. A majority of the participants (72.1%) occasionally accepted gifts such as stationery (57%), drug samples (54%), meals (38%), and sponsorship of educational activities (30%). The following characteristics were independently associated with physician-PR interaction: non-Saudi nationals, a higher monthly income, Western medical education, working in a private hospital, being a specialist or registrar (rather than resident or intern), working on certain specialties (such as psychiatry and family medicine), and having limited number of patients with high socioeconomic status. Although lower than seen in many parts of the world, a high prevalence of physician-PR inter.action in Saudi hospitals is reported. Delineating associated characteristics may assist with future interventions. Further research should focus on ethical, clinical, prescription, and economic impact of interaction as well as determining the best strategy to reduce negative impact.

Plant trial evaluations have been completed for two zirconium-based, non-chromium passivation systems previously identified as possible alternatives to cathodic dichromate (CDC) passivation for electrolytic tinplate (ETP). These trials were done on a commercial electrolytic tin plating line at Weirton Steel and extensive evaluations of the materials resulting from these trials have been completed. All this was accomplished as a collaborative effort under the AISI Technology Roadmap Program and was executed by seven North American Tin Mill Products producers [Bethlehem Steel (now acquired by International Steel Group (ISG)), Dofasco Inc., National Steel (now acquired by U.S. Steel), U.S. Steel, USS-Posco, Weirtonmore » Steel, and Wheeling-Pittsburgh Steel] with funding partially from the Department of Energy (DOE) and partially on an equal cost sharing basis among project participants. The initial phases of this project involved optimization of application procedures for the non-chromium systems in the laboratories at Bethlehem Steel and Betz Dearborn followed by extensive testing with various lacquer formulations and food simulants in the laboratories at Valspar and PPG. Work was also completed at Dofasco and Weirton Steel to develop methods to prevent precipitation of insoluble solids as a function of time from the zirconate system. The results of this testing indicated that sulfide staining characteristics for the non-chromium passivation systems could be minimized but not totally eliminated and neither system was found to perform quite as good, in this respect, as the standard CDC system. As for the stability of zirconate treatment, a method was developed to stabilize this system for a sufficient period of time to conduct plant trial evaluations but, working with a major supplier of zirconium orthosulfate, a method for long term stabilization is still under development.« less

Strong Electroweak Symmetry Breaking in the Large Hadron Collider Era

NASA Astrophysics Data System (ADS)

Evans, Jared Andrew

2011-12-01

With the Large Hadron Collider collecting data, both the pursuit of novel detection techniques and the exploration of new ideas are more important than ever. Novel detection techniques are essential in order for the community to garner the most worth from the machine. New ideas are needed both to expand the boundaries of what could be observed and to foster the creative mindset of the community that moves particle physics into fascinating, and often unexpected, directions. Discovering whether electroweak symmetry is broken strongly or weakly is one of the most pressing questions to be answered. Exploring the possibility of strong electroweak symmetry breaking is the topic of this work. The first of two major sectors in this work concerns the theory of conformal technicolor. We present the low energy minimal model for conformal technicolor and verify that it can satisfy current constraints from experiment. We will also provide a UV completion for this model, which realistically extends the sector with high-energy supersymmetry. Two complete models of flavor are presented. This is the first example of a complete, consistent model of strong electroweak symmetry breaking. The second of the two sectors discusses experimental signatures arising in a large class of general technicolor models at the Large Hadron Collider. The possible existence of narrow scalar states that can be produced via gluon-gluon fusion is first discussed. These states can decay into exotic final states of multiple electroweak gauge bosons, third generation particles and even light composite Higgs particles. A two Higgs doublet model is proposed as an effective way to model these exciting states. Lastly, we discuss the array of possible final states and their possible discovery.

Modelling of cooperating robotized systems with the use of object-based approach

Today's robotized manufacturing systems are characterized by high efficiency. The emphasis is placed mainly on the simultaneous work of machines. It could manifest in many ways, where the most spectacular one is the cooperation of several robots, during work on the same detail. What's more, recently a dual-arm robots are used that could mimic the manipulative skills of human hands. As a result, it is often hard to deal with the situation, when it is necessary not only to maintain sufficient precision, but also the coordination and proper sequence of movements of individual robots’ arms. The successful completion of this task depends on the individual robot control systems and their respective programmed, but also on the well-functioning communication between robot controllers. A major problem in case of cooperating robots is the possibility of collision between particular links of robots’ kinematic chains. This is not a simple case, because the manufacturers of robotic systems do not disclose the details of the control algorithms, then it is hard to determine such situation. Another problem with cooperation of robots is how to inform the other units about start or completion of part of the task, so that other robots can take further actions. This paper focuses on communication between cooperating robotic units, assuming that every robot is represented by object-based model. This problem requires developing a form of communication protocol that the objects can use for collecting the information about its environment. The approach presented in the paper is not limited to the robots and could be used in a wider range, for example during modelling of the complete workcell or production line.

Lack of knowledge of an NHS trust's major incident policies by clinical staff may result in poorly coordinated responses during a mass casualty incident (MCI). To audit knowledge of the major incident policy by clinical staff working in a central London major acute NHS trust designated to receive casualties on a 24-h basis during a MCI. A 12-question proforma was distributed to 307 nursing and medical staff in the hospital, designed to assess their knowledge of the major incident policy. Completed proformas were collected over a 2-month period between December 2006 and February 2007. A reply rate of 34% was obtained, with a reasonable representation from all disciplines ranging from nurses to consultants. Despite only 41% having read the policy in full, 70% knew the correct immediate action to take if informed of major incident activation. 76% knew the correct stand-down procedure. 56% knew the correct reporting point but less than 25% knew that an action card system was utilised. Nurses had significantly (p<0.01) more awareness of the policy than doctors. In view of the heightened terrorist threat in London, knowledge of major incident policy is essential. The high percentage of positive responses relating to immediate and stand-down actions reflects the rolling trust-wide MCI education programme and the organisational memory of the trust following several previous MCI in the capital. There is still scope for an improvement in awareness, however, particularly concerning knowledge of action cards, which are now displayed routinely throughout clinical areas and will be incorporated into induction packs.

The purpose of this study was to examine the career paths of alumni from the National Cancer Institute (NCI) Cancer Prevention Fellowship Program (CPFP), a structured in-house postdoctoral training program of 3–4 years duration, and specifically what proportion of the alumni were currently performing cancer prevention-related activities. The analyses here included 119 CPFP alumni and 85 unsuccessful CPFP applicants, all of whom completed postdoctoral training between 1987–2011 and are currently employed. Postdoctoral training experiences and current career outcomes data were collected via online surveys. Differences between groups were assessed using chi-square and Fisher’s exact test p-values and subsequent regression analyses adjusted for differences between the groups. Compared to 15.3% of unsuccessful CPFP applicants, 52.1% of CPFP alumni (odds ratio [OR] = 4.99, 95% confidence interval [95% CI): 1.91–13.0) were currently spending the majority of their time working in cancer prevention. Among those doing any cancer prevention-focused work, 54.3% of CPFP alumni spent the majority of their time performing cancer prevention research activities when compared to 25.5% of unsuccessful applicants (OR = 4.26, 95% CI: 1.38–13.2). In addition to the independent effect of the NCI CPFP, scientific discipline, and employment sector were also associated with currently working in cancer prevention and involvement in cancer prevention research-related activities. These results from a structured postdoctoral training program are relevant not only to the cancer prevention community but also to those interested in evaluating alignment of postdoctoral training programs with available and desired career paths more broadly.

In this study, we aimed to determine the perspectives of medical and radiation oncologists regarding consolidation radiotherapy in patients with a complete response after chemotherapy for Hodgkin’s and non-Hodgkin’s lymphomas. The survey was designed to identify demographic and occupational features of medical and radiation oncologists and their views on application of consolidation radiotherapy in their clinical practices, as based on a five-point Likert scale (never, rarely, sometimes, often, and always). The study covered 263, out of 935, physicians working in the oncology field as either medical or radiation oncologists; the rate of return on the invitations to participate was 28%. The majority of the participants were male radiation oncologists, with a duration of between 5 and 10 years of work as a university hospital official, and the mean age was 38 ± 14 (years). Although the most commonly followed international guidelines were NCCN, among the physicians, the majority of the respondents suggested that the guidelines were unclear regarding recommendations for consolidative radiotherapy. The administered dose for consolidative radiotherapy in lymphoma patients was indicated as 40 Gy by 49% of all the physicians and the most common cause of hesitancy concerning consolidative radiation treatment was the risk of secondary malignancies as a long-term adverse effect (54%). In conclusion, we suggest that medical oncologists could be most active in the treatment of lymphoma through a continuous training program about lymphomas and current national guidelines.

2011-03-01

It is now known that resident doctors registered for postgraduate studies are prone to work related stress and eventual burnout. Though stress can happen in any profession, reduced performance of resident doctors due to vocational stress could cause an increase in medical errors and thus affect the quality of life of the patients. Resident doctors at a Municipal hospital in India form a unique population as number of stresses they undergo are many and varied. To study the prevalence of work-related stress and its anticipated solutions among the resident doctors registered for postgraduate studies in clinical subjects at a tertiary Municipal hospital. A stratified sampling cross-sectional survey was conducted at the Inpatient, Outpatient, and Intensive Care Units at a tertiary Municipal hospital in Mumbai, India. Data collection was done using a validated 20-point questionnaire to assess the factors causing stress and their anticipated solutions. Simple percentage analysis of stress questionnaire. 71 resident doctors completed the survey. The major stressors in this cohort were inadequate hostel/quarter facilities (92.1%), and the need to perform extra duties (80.0%). Also, non-conducive environment for clinical training and studies (81.7%), inadequate study (78.9%) and break (81.2%), threat from deadly infections (74.6%), and overburdening with work (69.0%) were the other major stress causing factors. The perceived stress busters were good music (40.8%) and family and friends (40.8%). Eighty-seven percent of the respondents perceived regular physical exercise to be an effective mode of stress management and 83.8% expressed their need to have a simple therapeutic gymnasium established within the campus with a qualified trainer. There is a high level of work related stress among the resident doctors registered for postgraduate clinical studies at a tertiary Municipal hospital in Mumbai. One of the perceived stress busters is regular physical exercise that is structured and under supervision.

Purpose: To document clinical training and resident working conditions reported by chief residents during their residency. Methods and Materials: During the academic years 2005 to 2006, 2006 to 2007, and 2007 to 2008, the Association of Residents in Radiation Oncology conducted a nationwide survey of all radiation oncology chief residents in the United States. Chi-square statistics were used to assess changes in clinical training and resident working conditions over time. Results: Surveys were completed by representatives from 55 programs (response rate, 71.4%) in 2005 to 2006, 60 programs (75.9%) in 2006 to 2007, and 74 programs (93.7%) in 2007 tomore » 2008. Nearly all chief residents reported receiving adequate clinical experience in commonly treated disease sites, such as breast and genitourinary malignancies; and commonly performed procedures, such as three-dimensional conformal radiotherapy and intensity-modulated radiotherapy. Clinical experience in extracranial stereotactic radiotherapy increased over time (p < 0.001), whereas clinical experience in endovascular brachytherapy (p <0.001) decreased over time. The distribution of gynecologic and prostate brachytherapy cases remained stable, while clinical case load in breast brachytherapy increased (p = 0.006). A small but significant percentage of residents reported receiving inadequate clinical experience in pediatrics, seeing 10 or fewer pediatric cases during the course of residency. Procedures involving higher capital costs, such as particle beam therapy and intraoperative radiotherapy, and infrequent clinical use, such as head and neck brachytherapy, were limited to a minority of institutions. Most residency programs associated with at least one satellite facility have incorporated resident rotations into their clinical training, and the majority of residents at these programs find them valuable experiences. The majority of residents reported working 60 or fewer hours per week on required clinical duties. Conclusions: Trends in clinical training and resident working conditions over 3 years are documented to allow residents and program directors to assess their residency training.« less

Impact of the recent reduction in working hours (the 80 hour work week) on surgical resident cancer education.

PubMed

Vetto, John T; Robbins, Debra

2005-01-01

Resident work hours were recently reduced to 80 hours per week by a mandate from the Accreditation Council for Graduate Medical Education and subsequent Federal law (HR 3236). This mandate became effective July 1st, 2003. We sought to determine any impact this change had on perceived and real resident cancer education and knowledge. Of the total 85 residents in our large, university-based surgical training program, we focused on the 40 who had been in the clinical program (rather than research) before and after the work hour reduction. Perceived impact on cancer education was determined by survey, and real impact by before (2002) and after (2004) scores on the overall and cancer-specific portion of the annual American Board of Surgery In-Training Examination (ABSITE). All eligible residents responded to the survey. The majority (83% to 85%) indicated that exposure to cancer patients on wards and in clinics remained the same. Thirty percent felt that their exposure to cancer operations and tumor boards had decreased; 60% to 65% felt that exposure to these activities were unchanged. Approximately half of residents reported an increase in their cancer-related reading and Internet learning activities--the other half felt they had not changed. The majority (88%) reported no change in their participation in extraprogrammatic cancer-related continuing medical education activities. Of the survey responders, 23 had completed the ABSITE in both 2002 and 2004; their mean scores between the 2 time periods increased by 7% for the overall test and decreased by 3% for the cancer-specific portion. Overall, the recent reduction in work hours does not appear to have changed residents' experience with cancer patient care, although possible early reductions in attendance at cancer operations and tumor boards merits further study and possibly future schedule changes. The reported perceived increase in cancer-related reading and Internet learning has not yet translated into improved test scores.

To describe the current life situation of adults with congenital limb reduction deficiencies (CLRD), living in Sweden, regarding their main daily occupation, leisure activities and self-reported general health. A cross-sectional survey was conducted using a study-specific questionnaire, sent by post. Hundred and seventeen persons with different extent, forms and levels of CLRD (mean age 33 years) responded to the questionnaire. Work or study was the main occupation for 86% of the participants and 50% had completed a college or university education. About 7% were unemployed and 3% were on sick leave. The participants were highly involved in social and physical activities during leisure time. The majority reported good or very good general health. This study is the first investigation of the life situation of adults with CLRD described with a perspective from Swedish society. The participants were educated and worked to a great extent, which corresponds well to the Swedish population as a whole. Further research is needed, especially with a focus on the internal perspective of life situation, different aspects of work capacity, occurences of strain injuries and the benefit of assistive devices among adults with CLRD. Implications for Rehabilitation People with CLRD require a health care system with a multi-professional rehabilitation team offering regular contact during their life time. Educational system offering study counselling on all education levels (from primary school to university) is an important type of support for people with any kind of deficiency, in order to find suitable education and profession. Work is of importance for an acceptable life situation. Rehabilitation for people with CLRD should emphasise facilitating their ability to work, through engagement in individual personal capacity and self-efficacy. The majority of people with CLRD are users of prostheses and assistive devices. The benefits of the devices are basic but the rehabilitation should also include aspects of usability and use worthiness for individuals in performing their daily activities.

Major depressive disorder (MDD) represents a major social and economic health issue and constitutes a major risk factor for suicide. The molecular pathology of suicidal depression remains poorly understood, although it has been hypothesised that regulatory genomic processes are involved in the pathology of both MDD and suicidality. In this study, genome-wide patterns of DNA methylation were assessed in depressed suicide completers (n=20) and compared with non-psychiatric, sudden-death controls (n=20) using tissue from two cortical brain regions (Brodmann Area 11 (BA11) and Brodmann Area 25 (BA25)). Analyses focused on identifying differentially methylated regions (DMRs) associated with suicidal depression and epigenetic variation were explored in the context of polygenic risk scores for major depression and suicide. Weighted gene co-methylation network analysis was used to identify modules of co-methylated loci associated with depressed suicide completers and polygenic burden for MDD and suicide attempt. We identified a DMR upstream of the PSORS1C3 gene, subsequently validated using bisulfite pyrosequencing and replicated in a second set of suicide samples, which is characterised by significant hypomethylation in both cortical brain regions in MDD suicide cases. We also identified discrete modules of co-methylated loci associated with polygenic risk burden for suicide attempt, but not major depression. Suicide-associated co-methylation modules were enriched among gene networks implicating biological processes relevant to depression and suicidality, including nervous system development and mitochondria function. Our data suggest that there are coordinated changes in DNA methylation associated with suicide that may offer novel insights into the molecular pathology associated with depressed suicide completers.

Residents have a major role in teaching students, yet little has been written about the effects of resident work hour restrictions on medical student education. Our objective was to determine the effects of resident work hour restrictions on medical student education. We compared student responses pre work hour restrictions with those completed post work hour restrictions. Students on required Internal Medicine, Surgery, and Pediatric clerkships at the University of Minnesota. Two thousand eight hundred twenty-five student responses on end-of-clerkship surveys. Students reported 1.6 more hours per week of teaching by residents (95%CI 0.8-2.6) in the post work hours era. Students' ratings of the overall quality of their teaching on the ward did not change appreciably, 0.05 points' decline on a 5-point scale (P = .05). Like the residents, students worked fewer hours per week (avg. 1.5 hours less, 95%CI 0.4-2.6). There was no change in quality or quantity of attending teaching, students' relationships with their patients, or the overall value of the clerkships. Whereas resident duty hour restrictions at our institution have had minimal effect on students' ratings of the overall teaching quality, they do report being taught more by their residents. This may be a factor of decreased resident fatigue or an increased sense of well-being; but more study is needed to clarify the causes of our observations.

Ten thousand steps: a pedometer study of junior dentists in a major British teaching hospital and a district general hospital.

2017-05-01

Sedentary behaviour is widely associated with deleterious health outcomes that in modern medicine have similar connotations to smoking tobacco and alcohol misuse. The integration of e-portfolio, e-logbook, British National Formulary (BNF) and encrypted emails has made smartphones a necessity for trainees. Smartphones also have the ability to record the amount of exercise taken, which allows activity at work to be monitored. The aim of this study to compare the activity of the same group of dental core trainees when they worked within a large multisite teaching hospital and a smaller district general hospital, to find out if supplementary activity was needed outside work. Data were collected from smartphones. To ensure continuity, data were collected only from those who had calibrated iPhones (n=10). At the teaching hospital six of the trainees walked over 10 000 steps a day while working (mean (SD) 10 004 (639)). At the district hospital none of the trainees walked 10 000 steps. The mean (SD) number of steps completed by all trainees was 6265 (119). Walking at work provides the full quota of recommended daily exercise most of the time for those working in the teaching hospital, but additional exercise is occasionally required. While working at the district hospital they walk less, meaning that they should try to increase their activity outside work. Trainees working in the teaching hospital walk significantly more steps than in the district hospital. Copyright © 2016 The British Association of Oral and Maxillofacial Surgeons.

Women in physics: A comparison to science, technology, engineering, and math education over four decades

NASA Astrophysics Data System (ADS)

Lim, Gloria

Women have been underrepresented in many STEM fields including physics. The gap appears to be largely attributable to a lack of women pursuing physics in college, and little is known about the characteristics and career interests of women who do plan to major in physics. Using nationwide data on first-time, full-time college students, this study set out to: (1) document national trends in plans to major in physics among women entering college; (2) document the career aspirations of women who intend to major in physics; and (3) explore the characteristics of women who intend to major in physics and how this population has evolved across time. The results show that women's interest in physics has been consistently low in the past four decades. The most popular career aspiration among women who plan to major in physics is research scientist, although this career aspiration is declining in popularity. Further, this study identifies a distinctive profile of the average female physics student as compared to women in other STEM fields and women across all majors. Women who plan to pursue a physics major tend to be confident in their math abilities, value college as an opportunity to learn, plan to attend graduate school, and are less likely than women in other fields to have a social activist orientation. The paper concludes with implications for scholars, educators, administrators, and policymakers as they seek to recruit more women in to the physics field. This research is supported by the National Science Foundation, HRD No. 1135727. Part of this work was also completed with the support of a Fulbright Fellowship in Finland.

Access to and support for continuing professional education amongst Queensland nurses: 2004 and 2007.

2010-02-01

This paper reports on the findings of a prospective exploratory study related to nurses' self-reports of continuing professional education access and support. The data were gathered by two postal surveys undertaken in 2004 and 2007 each which sampled 3000 nurses of the 30,000 nurse members of the industrial body - Queensland Nurses' Union. The response rates were 44.9% and 39.7% for 2004 and 2007, respectively. Over 85% of the nurses reported they had access to continuing professional education activities. However, it is apparent that the majority of these activities are either partially or completely self-funded. Further, between 2004 and 2007 the amount of financial support provided by employers for continuing education and training activities has decreased significantly. While there were differences between 2004 and 2007, the major barrier to be able to attend continuing professional education were financial (could not afford the fee involved; could not afford to take unpaid leave to attend). Another major barrier in both 2004 and 2007 was having the time to undertake the activity. Analysis for differences between nurses in different geographical locations indicated that distance remains a major barrier for nurses in rural and remote areas. These quantitative findings were supported by the qualitative findings on nurses' work where 'education and training' was, overall, the fifth highest ranked issue requiring further attention.

Waste from pulp and paper mills consist of sugar-rich fractions comprising hemicellulose derivatives and cellulose by-products. A complete characterisation of the waste streams is necessary to study the possibilities of an existing mill. In this work, four chromatographic methods have been developed to obtain the most suitable chromatographic method conditions for measuring woody feedstocks, lignocellulosic hydrolysates and cellulose pulp in sulphite pulping processes. The analysis of major and minor monosaccharides, aliphatic carboxylic acids and furfurals has been optimised. An important drawback of the spent liquors generated after sulphite pulping is their acidic nature, high viscosity and adhesive properties that interfere in the column lifetime. This work recommends both a CHO-782Pb column for the sugar analysis and an SH-1011 resin-based cross-linked gel column to separate low-molecular-weight chain acids, alcohols and furfurals. Such columns resulted in a good separation with long lifetime, wide pH operating range and low fouling issues.

Incorporation of reporter genes within virus genomes is an indispensable tool for interrogation of virus biology and pathogenesis. In previous work, we incorporated a fluorophore into a viral ORF by attaching it to the viral gene via a P2A ribosomal skipping sequence. This recombinant Nipah virus, however, was attenuated in vitro relative to WT virus. In this work, we determined that inefficient ribosomal skipping was a major contributing factor to this attenuation. Inserting a GSG linker before the P2A sequence resulted in essentially complete skipping, significantly improved growth in vitro, and WT lethality in vivo. To the best of our knowledge, this represents the first time a recombinant virus of Mononegavirales with integration of a reporter into a viral ORF has been compared with the WT virus in vivo. Incorporating the GSG linker for improved skipping efficiency whenever functionally important is a critical consideration for recombinant virus design.

In Italy, 5 millions migrants live and work. Among them, the employment rate is much higher in comparison with the Italians' one (75% versus 62%). The well known "healthy migrant effect" is confirmed by statistics from the National Institute for Statistics: according to it, migrants access the National Health System for pregnancy and delivery and for accidents. The chronic pathology is not a major concern. Moreover, their work ability is generally complete, without any limitation. Nevertheless, migrants seem to represent a vulnerable subgroup with regard to the risk of 1) occupational injuries: this is strongly linked with the risk of Tetanus infection; 2) disorders of the metabolism, like hyperglycaemia and hyperlipemia, which is linked to a higher cardiovascular risk. In this light data from health surveillance carried out by the International centre for Rural Health of the San Paolo University Hospital in agricultural setting in the Region of Lombardy and the participation of the Centre itself to the Promovax EC-cofunded project are presented.

Verbal makes it positive, spatial makes it negative: working memory biases judgments, attention, and moods.

PubMed

Storbeck, Justin; Watson, Philip

2014-12-01

Prior research has suggested that emotion and working memory domains are integrated, such that positive affect enhances verbal working memory, whereas negative affect enhances spatial working memory (Gray, 2004; Storbeck, 2012). Simon (1967) postulated that one feature of emotion and cognition integration would be reciprocal connectedness (i.e., emotion influences cognition and cognition influences emotion). We explored whether affective judgments and attention to affective qualities are biased by the activation of verbal and spatial working memory mind-sets. For all experiments, participants completed a 2-back verbal or spatial working memory task followed by an endorsement task (Experiments 1 & 2), word-pair selection task (Exp. 3), or attentional dot-probe task (Exp. 4). Participants who had an activated verbal, compared with spatial, working memory mind-set were more likely to endorse pictures (Exp. 1) and words (Exp. 2) as being more positive and to select the more positive word pair out of a set of word pairs that went 'together best' (Exp. 3). Additionally, people who completed the verbal working memory task took longer to disengage from positive stimuli, whereas those who completed the spatial working memory task took longer to disengage from negative stimuli (Exp. 4). Interestingly, across the 4 experiments, we observed higher levels of self-reported negative affect for people who completed the spatial working memory task, which was consistent with their endorsement and attentional bias toward negative stimuli. Therefore, emotion and working memory may have a reciprocal connectedness allowing for bidirectional influence.

2017-10-01

The therapeutic relationship is a critical component of psychological treatment. Strain can occur in the relationship, particularly when working with offenders, and more specifically, those offenders with interpersonal difficulties; strain can lead to a rupture, which may affect treatment participation and performance. This study examined ruptures in the therapeutic relationship in sexual offenders participating in offense-focused group treatment. Fifty-four sex offenders rated the therapeutic alliance at the commencement and completion of treatment; at the completion of treatment, they also reported on the occurrence of ruptures and whether they believed these ruptures were repaired. Ruptures were separated by type, according to severity-Each relationship was therefore characterized as experiencing no rupture, a minor rupture, or a major rupture. Offender characteristics including interpersonal style (IPS) and psychopathy were assessed at the commencement of treatment; their relationship with ruptures was examined. Results revealed that more than half of the offenders (approximately 55%) experienced a rupture in the therapeutic alliance, with one in four of these ruptures remaining unresolved. Offenders who did not report a rupture rated the therapeutic alliance significantly higher at the end of treatment compared with those offenders who reported a rupture that was not repaired. Offenders who reported a major rupture in the therapeutic relationship were higher in interpersonal hostility and hostile-dominance. No interpersonal or offense-specific factors affected the likelihood of a rupture repair.
