    Namratha, P.; Kishor, M.; Sathyanarayana Rao, T. S.; Raman, Rajesh

    2015-01-01

    Background: Suicide is one of the leading causes of preventable deaths. Recent data suggest South India as one of the regions with highest suicide rates in the world. In 2013, 134,799 people committed suicide in India according to the statistics released by the National Crime Records Bureau. Suicide note is one of the most important sources to understand suicide, which may be beneficial in suicide prevention. Studies on suicidal notes from this part of the world are sparse. Objective: The aim was to study the themes in suicide notes that might be useful in prevention strategies. Materials and Methods: A descriptive study of all suicide notes of those individuals who committed suicide between 2010 and 2013 available with Police Department, Mysore district was obtained and analyzed. Results: A total of 22 suicide note were available. A majority of suicide note was in age group of 16–40 years (86%) and most were men (59%). All suicide notes were handwritten, the majority (70%) in regional language Kannada. Length of notes varied from just few words to few pages. Contents of suicide notes included apology/shame/guilt (80%), love for those left behind (55%) and instruction regarding practical affairs (23%). Most have blamed none for the act (50%). 23% mentioned that they are committing suicide to prove their innocence. 32% mentioned a last wish. Conclusion: The majority of suicidal note contained “guilt” which is a strong indicator of possible depression in deceased. Creating awareness about suicide among public and ensuring access to professionals trained in suicide prevention is need of the hour in this part of the world. PMID:26816426

    We propose the modification to the Anderson method of work function change (Δϕ) measurements. In this technique, the kinetic energy of the probing electrons is already low enough for non-destructive investigation of delicate molecular systems. However, in our implementation, all electrodes including filament of the electron gun are polarized positively. As a consequence, electron bombardment of any elements of experimental system is eliminated. Our modification improves cleanliness of the ultra-high vacuum system. As an illustration of the solution capabilities, we present Δϕ of the Ag(100) surface induced by cobalt phthalocyanine layers.

  3. Social Work Assessment Notes: A Comprehensive Outcomes-Based Hospice Documentation System.

    PubMed

    Hansen, Angela Gregory; Martin, Ellen; Jones, Barbara L; Pomeroy, Elizabeth C

    2015-08-01

    This article describes the development of an integrated psychosocial patient and caregiver assessment and plan of care for hospice social work documentation. A team of hospice social workers developed the Social Work Assessment Notes as a quality improvement project in collaboration with the information technology department. Using the Social Work Assessment Tool as an organizing framework, this comprehensive hospice social work documentation system is designed to integrate assessment, planning, and outcomes measurement. The system was developed to guide the assessment of patients' and caregivers' needs related to end-of-life psychosocial issues, to facilitate collaborative care plan development, and to measure patient- and family-centered outcomes. Goals established with the patient and the caregiver are documented in the plan of care and become the foundation for patient-centered, strengths-based interventions. Likert scales are used to assign numerical severity levels for identified issues and progress made toward goals and to track the outcome of social work interventions across nine psychosocial constructs. The documentation system was developed for use in an electronic health record but can be used for paper charting. Future plans include automated aggregate outcomes measurement to identify the most effective interventions and best practices in end-of-life care.

  11. A note on non-equilibrium work fluctuations and equilibrium free energies

    NASA Astrophysics Data System (ADS)

    Suman Kalyan, M.; Anjan Prasad, G.; Sastry, V. S. S.; Murthy, K. P. N.

    2011-04-01

    We consider in this paper, a few important issues in non-equilibrium work fluctuations and their relations to equilibrium free energies. First we show that the Jarzynski identity can be viewed as a cumulant expansion of work. For a switching process which is nearly quasistatic the work distribution is sharply peaked and Gaussian. We show analytically that dissipation given by average work minus reversible work WR, decreases when the process becomes more and more quasistatic. Eventually, in the quasistatic reversible limit, the dissipation vanishes. However the estimate of p, the probability of violation of the second law given by the integral of the tail of the work distribution from -∞ to WR, increases and takes a value of 0.5 in the quasistatic limit. We show this analytically employing Gaussian integrals given by error functions and the Callen-Welton theorem that relates fluctuations to dissipation in process that is nearly quasistatic. Then we carry out Monte Carlo simulation of non-equilibrium processes in a liquid crystal system in the presence of an electric field and present results on reversible work, dissipation, probability of violation of the second law and distribution of work.

  12. Sex work: a comparative study.

    PubMed

    McCarthy, Bill; Benoit, Cecilia; Jansson, Mikael

    2014-10-01

    Explanations of adult involvement in sex work typically adopt one of two approaches. One perspective highlights a variety of negative experiences in childhood and adolescence, including physical and sexual abuse, family instability, poverty, associations with "pimps" and other exploiters, homelessness, and drug use. An alternative account recognizes that some of these factors may be involved, but underscores the contribution of more immediate circumstances, such as current economic needs, human capital, and employment opportunities. Prior research offers a limited assessment of these contrasting claims: most studies have focused exclusively on people working in the sex industry and they have not assessed the independent effects of life course variables central to these two perspectives. We add to this literature with an analysis that drew on insights from life course and life-span development theories and considered the contributions of factors from childhood, adolescence, and adulthood. Our comparative approach examined predictors of employment in sex work relative to two other low-income service or care work occupations: food and beverage serving and barbering and hairstyling. Using data from a study of almost 600 workers from two cities, one in Canada and the other in the United States, we found that both immediate circumstances and negative experiences from early life are related to current sex work involvement: childhood poverty, abuse, and family instability were independently associated with adult sex work, as were limited education and employment experience, adult drug use, and marital status.

    What if you had access to all your students' notes, their questions, their answers to questions you posed in class and when they were confused in class. What could you do with that information to help guide your students. With the advent of in-class tools like LectureTools it is now possible to have such access to student data. This paper describes on-going research at the University of Michigan to explore how best to mine student notes and questions to provide adaptive learning opportunities to students. Student notes are parsed in real-time searching for keywords from the geosciences. These words and phrases are then linked to a variety of resources for those wishing further clarification. This presentation will demonstrate the tools that have been generated for students and report on the students' assessment of the value of such information. The presentation will use LectureTools to demonstrate the crowdsourcing. Attendees are encouraged to bring a mobile device to the session.

  1. Race, space, place: notes on the racialisation and spatialisation of commercial sex work in Dubai, UAE.

    PubMed

    Mahdavi, Pardis

    2010-11-01

    This paper focuses on the perceived racialisation and resultant spatialisation of commercial sex in Dubai. In recent years, the sex industry in Dubai has grown to include women from the Middle East, Eastern Europe, East Asia and Africa. With the increase in sex workers of different nationalities has come a form of localised racism that is embedded in structures and desires seen within specific locations. The physical spatialisation of sex work hinges on perceived race and produces distinct income generating potential for women engaged in the sex industry in Dubai. The social and physical topography of Dubai is important in marginalising or privileging these various groups of sex workers, which correlates race, space and place with rights and assistance. I begin with a description of the multidirectional flows of causality between race, space, place and demand. I then discuss how these various groups are inversely spatialised within the discourse on assistance, protection and rights. The findings presented here are based on ethnographic research conducted with transnational migrants in the UAE in 2004, 2008 and 2009.

    2010-03-01

    Although the use of anecdotal notes by faculty to document clinical performance is thought to be a common practice, no empirical study of this evaluation tool has been conducted. To investigate the frequency and pattern of use, a faculty questionnaire was developed using the Context, Input, Process, Product (CIPP) evaluation model as a framework. The model was adapted to focus on clinical nursing education. Sixty-four nursing faculty from six schools participated in the regional study. A descriptive design was used to collect quantitative data from clinical faculty. Findings indicated that 97% of clinical faculty use anecdotal notes during the student evaluation process, and the majority of faculty do so on a weekly basis. Based on faculty feedback and the CIPP evaluation model, a clinical nursing faculty tool was developed after study completion to support clinical faculty in note use.

    Over half-a-million adolescents take part in each cycle of the Program for International Student Assessment (PISA). Yet often, researchers and policy makers across the globe tend to focus their attention primarily on the academic trajectories of adolescents hailing from highly successful education systems. Hence, a vast majority of the adolescent population who regionally and globally constitute the 'long tail of underachievement' often remain unnoticed and underrepresented in the growing literature on adolescents' academic trajectories. The present study, therefore, explored the relations of dispositions toward mathematics, subjective norms in mathematics, and perceived control of success in mathematics to mathematics work ethic as well as mathematics performance; and the mediational role of mathematics work ethic in the association between dispositional, normative, and control beliefs and mathematics performance among adolescents in one of the lowest performing education systems, Qatar. Structural equation modeling (SEM) analyses revealed that Qatari adolescents' dispositional, normative, and control beliefs about mathematics were significantly associated with their mathematics work ethic and mathematics performance, and mathematics work ethic significantly mediated the relationship between dispositional, normative, and control beliefs about mathematics and mathematics performance. However, multi-group SEM analyses indicated that these relationships were not invariant across the gender and the SES groups.

    Illumination conditions appear to influence working efficacy in everyday life. In the present study, we obtained electroencephalogram (EEG) correlates of working-memory load, and investigated how these waveforms are modulated by illumination conditions. We hypothesized that illumination conditions may affect cognitive performance. We designed an EEG study to monitor and record participants' EEG during the Sternberg working memory task under four different illumination conditions. Illumination conditions were generated with a factorial design of two color-temperatures (3000 and 7100 K) by two illuminance levels (150 and 700 lx). During a working memory task, we observed that high illuminance led to significantly lower frontal EEG theta activity than did low illuminance. These differences persisted despite no significant difference in task performance between illumination conditions. We found that the latency of an early event-related potential component, such as N1, was significantly modulated by the illumination condition. The fact that the illumination condition affects brain activity but not behavioral performance suggests that the lighting conditions used in the present study did not influence the performance stage of behavioral processing. Nevertheless, our findings provide objective evidence that illumination conditions modulate brain activity. Further studies are necessary to refine the optimal lighting parameters for facilitating working memory.

    Music therapists are constantly called upon to justify their work through research projects and evaluation processes. Rarely do we get the opportunity to talk personally about our work, the effects it has on us as music therapists, indeed, as human beings. This paper traces my own journey as a music therapist working with the terminally ill. Using audio extracts of music improvised with patients at the end of their lives, the concept of "attention" in music is addressed and explored. The paper will investigate: a) What is the difference between the quality of attention that is available to ourselves and our patients "in" music, as opposed to other ways of being together?; b) What does musical experience, particularly when achieved through improvisation, enable us and our patients to be that we cannot achieve in other ways?; c) Can "being in music" with another person fulfill a sense of longing that is evident in people at the end of their lives? In her book Waiting For God, Simone Weil suggests, "Those who are unhappy have no need for anything else in this world other than people capable of giving them their attention..." (1). Can the improvisation of music offer a unique and uncomplicated medium for being close?

    AIM: To evaluate the feasibility of diagnostic and therapeutic transgastric (TG) peritoneoscopic interventions with a forward-viewing endoscopic ultrasound (FV-EUS). METHODS: This prospective endoscopic experimental study used an animal model. Combined TG peritoneoscopic interventions and EUS examination of the intra-abdominal organs were performed using an FV-EUS on 10 animal models (1 porcine and 9 canine). The procedures carried out include EUS evaluation and endoscopic biopsy of intraperitoneal organs, EUS-guided fine needle aspiration (EUS-FNA), EUS-guided radiofrequency ablation (EUS-RFA), and argon plasma coagulation (APC) for hemostatic control. The animals were kept alive for 7 d, and then necropsy was performed to evaluate results and complications. RESULTS: In all 10 animals, TG peritoneoscopy, followed by endoscopic biopsy for the liver, spleen, abdominal wall, and omentum, was performed successfully. APC helped control minor bleeding. Visualization of intra-abdominal solid organs with real-time EUS was accomplished with ease. Intraperitoneal EUS-FNA was successfully performed on the liver, spleen, and kidney. Similarly, a successful outcome was achieved with EUS-RFA of the hepatic parenchyma. No adverse events were recorded during the study. CONCLUSION: Peritoneoscopic natural orifice transluminal endoscopic surgery (NOTES) interventions through FV-EUS were feasible in providing evaluation and performing endoscopic procedures. It promises potential as a platform for future EUS-based NOTES. PMID:24222961

  7. Training in summarizing notes: Effects of teaching students a self-regulation study strategy in science learning

    NASA Astrophysics Data System (ADS)

    Nebres, Michelle

    The last two decades of national data assessments reveal that there has been a sharp decline in nationwide standardized test scores. International assessment data show that in 2012 a very low amount of American students were performing at proficiency or above in science literacy. Research in science literacy education suggests that students benefit most when they are self-regulated (SR) learners. Unfortunately, SR poses a challenge for many students because students lack these skills. The effects of having learned few SR strategies at an early age may lead to long term learning difficulties--preventing students from achieving academic success in college and beyond. As a result, some researchers have begun to investigate how to best support students' SR skills. In order for studying to be successful, students need to know which SR study strategies to implement. This can be tricky for struggling students because they need study strategies that are well defined. This needs to be addressed through effective classroom instruction, and should be addressed prior to entering high school in order for students to be prepared for higher level learning. In this study, students underwent a treatment in which they were taught a SR study strategy called summarizing notes. A crossover repeated measures design was employed to understand the effectiveness of the treatment. Results indicated a weak, but positive correlation between how well students summarized notes and how well they performed on science tests. Self-regulation skills are needed because these are the types of skills young adults will use as they enter the workforce. As young adults began working in a professional setting, they will be expected to know how to observe and become proficient on their own. This study is pertinent to the educational field because it is an opportunity for students to increase SR, which affords students with the skills needed to be a lifelong learner.

    With this editorial note we would like to update you on the performance of the International Journal of Applied Earth Observation and Geoinformation (JAG) and inform you about changes that have been made to the composition of the editorial team. Our Journal publishes original papers that apply earth observation data for the management of natural resources and the environment. Environmental issues include biodiversity, land degradation, industrial pollution and natural hazards such as earthquakes, floods and landslides. As such the scope is broad and ranges from conceptual and more fundamental work on earth observation and geospatial sciences to the more problem-solving type of work. When I took over the role of Editor-in-Chief in 2012, I together with the Publisher set myself the mission to position JAG in the top-3 of the remote sensing and GIS journals. To do so we strived at attracting high quality and high impact papers to the journal and to reduce the review turnover time to make JAG a more attractive medium for publications. What has been achieved? Have we reached our ambitions? We can say that: The submissions have increased over the years with over 23% for the last 12 months. Naturally not all may lead to more papers, but at least a portion of the additional submissions should lead to a growth in journal content and quality.

    2011-03-01

    Changing population demographics and immigration patterns have resulted in increasing numbers of Canadians who report speaking a language other than French or English. Inclusion of English-as-a-second-language (ESL) immigrants in cancer education research is critical if disparities in access and use of preventive health care services are to be addressed. This article describes the challenges experienced recruiting and interviewing older ESL immigrant women for a colon cancer prevention study. Factors influencing the recruitment and interview of ESL immigrant women were identified through regular team meetings, interviews, and reflective practice notes. Issues included the importance of community contacts, language barriers, and the motivations of the women for participating. Recommendations for recruitment and inclusion of ESL immigrants in cancer education research are provided.

    Suicide notes from two groups of protest suicides in South Korea during the period 1975-2003 were compared: suicide notes from students (n =16) and suicide notes from workers (n = 15). The students appeared to be acting upon abstract ideals, including the oppression of the masses by the government and the American forces in Korea, and they typically urged the reunification of Korea. The workers were acting upon more local concerns, such as the oppression of their union by the government and the companies and the policies of their specific companies.

    OBJECTIVES: To study the determinants of signs of carpal tunnel syndrome (CTS) in repetitive industrial work, with special attention to occupational constraints at group level and management practices of the companies. METHOD: A cross sectional study was conducted in three sectors: assembly line; clothing and shoe industry; food industry. A total of 1210 workers in repetitive work, from 53 different companies, was compared with a control group of 337 workers. Constraints at the workplace were partly self declared, and partly assessed by the occupational physicians in charge of the employees of the company. The definition of CTS was based on a standardised clinical examination. RESULTS: CTS was associated with repetitive work, especially packaging. It was more frequent among subjects who declared psychological and psychosomatic problems and those with a body mass index > or = 27. Dissatisfaction with work, lack of job control, short cycle time, and having to press repeatedly with the hand were associated with the syndrome. An odds ratio (OR) of 2.24 was found for "just in time" production. CONCLUSION: The results emphasise the complexity of the determinants of CTS, the role of psychosocial factors at work and the potentially negative effects of some practices of the companies aimed at enhancing their competitiveness.   PMID:9624269

    The failure to integrate environmental and organizational interventions may help explain the lack of success of many change efforts. The high rate of failure for change efforts (50% to 90% failure rates) has been noted by many writers. While specific causes of failure are diverse, a common theme has been failure to consider the organization as a system. That is, either significant aspects of the organization were ignored during the intervention or potential impacts of changes on the elements were overlooked or underestimated. Our own training, technical literature, and professional culture lead us to limited understandings of complex organizations. Change agents must consider all relevant components of organizational performance if interventions are to be meaningful and successful. This study demonstrated the value of an integrated organizational intervention involving redesign of the physical environment, introduction of a new information system, work process improvement, and extended organizational development intervention. The outcomes were extremely positive. The cost of improvement efforts was found to be recaptured within a short time, easily justifying the expenditures. One conclusion from the study is that integrated interventions are very powerful. Integrating improvement of the physical environment with organizational development and technological innovation greatly enhances the likelihood of achieving a successful intervention.

    1994-01-01

    STUDY OBJECTIVE--The UK National Case-Control Study was carried out to investigate the relationship between oral contraceptive use and breast cancer risk. This study investigates whether general practitioner notes could be used as the sole data source for epidemiological studies of young women and what the effect would be on non-response and recall bias. DESIGN--Case-control study with data on gynaecological, obstetric, and contraceptive history collected at interview and from general practitioners' notes. Information from these two sources was compared. SETTING--This was a population-based study. PARTICIPANTS--Altogether 755 women with breast cancer aged under 36 years at diagnosis, each with an age-matched control, participated in the study. Response rates at interview were 72% and 89% for cases and controls but GP data were available for 90% of the 1049 case and first-selected control pairs. MAIN RESULTS--There was generally good agreement between the two data sources with respect to obstetric history and gynaecological procedures (hysterectomy, oophorectomy, and tubal ligation). The use of intra-uterine devices, or diaphragm, and partner's vasectomy were not reliably recorded in the GP's notes. The overall results of the UK study would have been qualitatively the same with respect to the relationship between oral contraceptive use and breast cancer risk if GP notes only had been used, in spite of the fact that only about half of all oral contraceptive usage was recorded in the notes. Response rates would have been higher, recall bias eliminated, and the cost of the study halved. CONCLUSIONS--When planning case-control studies in young women, the possibility of using GP notes as the primary data source should be considered. Lack of data on potential confounding factors is a possible drawback to such use. The practice of destroying GP's notes shortly after the death of patients seriously restricts the possibility of using these notes when studying rapidly fatal

    1988-08-01

    Experiments were designed to test the traditional assumption that during level walking all of the energy from oxidation of fuel appears as heat and no work is done. Work is force expressed through distance, or energy transferred from a man to the environment, but not as heat. While wearing a suit calorimeter in a respiration chamber, five women and five men walked for 70 to 90 min on a level treadmill at 2.5, 4.6, and 6.7 km.h-1 and pedalled a cycle ergometer for 70 to 90 min against 53 and 92 W loads. They also walked with a weighted backpack and against a horizontal load. During cycling, energy from fuel matched heat loss plus the power measured by the ergometer. During walking, however, energy from fuel exceeded that which appeared as heat, meaning that work was done. The power increased with walking speed; values were 14, 29, and 63 W, which represented 11, 12, and 13% of the incremental cost of fuel above the resting level. Vertical and horizontal loads increased the fuel cost and heat loss of walking but did not alter the power output. This work energy did not re-appear as thermal energy during 18 h of recovery. The most likely explanation of the work done is in the inter-action between the foot and the ground, such as compressing the heel of the shoe and bending the sole. We conclude that work is done in level walking.

    A simplified data analysis protocol, for dielectric spectroscopy use to study conductivity percolation in dehydrating granular media is discussed. To enhance visibility of the protonic conductivity contribution to the dielectric loss spectrum, detrimental effects of either low-frequency dielectric relaxation or electrode polarization are removed. Use of the directly measurable monofrequency dielectric loss factor rather than estimated DC conductivity to parameterize the percolation transition substantially reduces the analysis work and time.

Methods: WAA and NOA in the United States were compared using cases reported to the National Institute for Occupational Safety and Health (NIOSH) from four state Sentinel Event Notification Systems for Occupational Risks (SENSOR) surveillance programmes for 1993–95. Results: A total of 210 WAA cases and 891 NOA cases were reported. WAA cases reported mineral and inorganic dusts as the most common exposure agent, as opposed to NOA cases, in which diisocyanates were reported most frequently. A similar percentage of WAA and NOA cases still experienced breathing problems at the time of the interview or had visited a hospital or emergency room for work related breathing problems. NOA cases were twice as likely to have applied for workers' compensation compared with WAA cases. However, among those who had applied for worker compensation, approximately three-fourths of both WAA and NOA cases had received awards. The services and manufacturing industrial categories together accounted for the majority of both WAA (62%) and NOA (75%) cases. The risk of WAA, measured by average annual rate, was clearly the highest in the public administration (14.2 cases/105) industrial category, while the risk of NOA was increased in both the manufacturing (3.2 cases/105) and public administration (2.9 cases/105) categories. Conclusions: WAA cases reported many of the same adverse consequences as NOA cases. Certain industries were identified as potential targets for prevention efforts based on either the number of cases or the risk of WAA and NOA. PMID:15150390

    This study aimed at assessing effect of the four dimensions of work-family conflicts (strain and time-based work interference into family and family interference into work) on sleep disturbance in Malaysian working women. This cross-sectional study was conducted among 325 Malaysian married working women. Multiple-stage simple random sampling method was used to recruit women from public service departments of Malaysia. Self-administrated questionnaires were used to measure the study variables and data were analyzed using SPSS version 21. We found that high level of the four dimensions of work-family conflicts significantly increase sleep disturbance. Our analyses also revealed an age-dependent effect of the work-family conflict on sleep disturbance. Women in their 20 to 30 yr old suffer from sleep disturbance due to high level of time-based and strain-based work-interference into family. However, the quality of sleep among women aged 30–39 were affected by strain-based family-interference into work. Finally, women older than 40 yr had significantly disturbed sleep due to strain-based work-interference into family as well as time-based family interference into work. Our findings showed that sleep quality of working women might be disturbed by experiencing high level of work-family conflict. However, the effects of inter-role conflicts on sleep varied among different age groups. PMID:26423332

    PubMed Central

    Abbasi, Hamid

    2016-01-01

    Background Minimally invasive direct thoracic interbody fusion (MIS-DTIF) is a new single surgeon procedure for fusion of the thoracic vertebrae below the scapula (T6/7) to the thoracolumbar junction. In this proof of concept study, we describe the surgical technique for MIS-DTIF and report our experience and the perioperative outcomes of the first four patients who underwent this procedure. Study design/setting In this study we attempt to establish the safety and efficacy of MIS-DTIF. We have performed MIS-DTIF on six spinal levels in four patients with degenerative disk disease or disk herniation. We recorded surgery time, blood loss, fluoroscopy time, complications, and patient-reported pain. Methods Throughout the MIS-DTIF procedure, the surgeon is aided by biplanar fluoroscopic imaging and electrophysiological monitoring. The surgeon approaches the spine with a series of gentle tissue dilations and inserts a working tube that establishes a direct connection from the outside of the skin to the disk space. Through this working tube, the surgeon performs a discectomy and inserts an interbody graft or cage. The procedure is completed with minimally invasive (MI) posterior pedicle screw fixation. Results For the single level patients the mean blood loss was 90 ml, surgery time 43 minutes, fluoroscopy time 293 seconds, and hospital stay two days. For the two-level surgeries, the mean blood loss was 27 ml, surgery time 61 minutes, fluoroscopy time 321 seconds, and hospital stay three days. We did not encounter any clinically significant complications. Thirty days post-surgery, the patients reported a statistically significant reduction of 5.3 points on a 10-point sliding pain scale. Conclusions MIS-DTIF with pedicle screw fixation is a safe and clinically effective procedure for fusions of the thoracic spine. The procedure is technically straightforward and overcomes many of the limitations of the current minimally invasive (MI) approaches to the thoracic spine. MIS

Because ground-based telescopes have life spans of several decades, it is only natural that they continuously reinvent themselves. Literally, the GREGOR telescope builds on the foundations of the venerable Gregory-Coudé Telescope (GCT) at Observatorio del Teide, Tenerife, Spain. Acknowledging the fact that new discoveries in observational solar physics are driven by larger apertures to collect more photons and to scrutinize the Sun in finer detail, the GCT was decommissioned and the building was made available to the GREGOR project.

  4. NOTE: A feasibility study of markerless fluoroscopic gating for lung cancer radiotherapy using 4DCT templates

    A major difficulty in conformal lung cancer radiotherapy is respiratory organ motion, which may cause clinically significant targeting errors. Respiratory-gated radiotherapy allows for more precise delivery of prescribed radiation dose to the tumor, while minimizing normal tissue complications. Gating based on external surrogates is limited by its lack of accuracy, while gating based on implanted fiducial markers is limited primarily by the risk of pneumothorax due to marker implantation. Techniques for fluoroscopic gating without implanted fiducial markers (markerless gating) have been developed. These techniques usually require a training fluoroscopic image dataset with marked tumor positions in the images, which limits their clinical implementation. To remove this requirement, this study presents a markerless fluoroscopic gating algorithm based on 4DCT templates. To generate gating signals, we explored the application of three similarity measures or scores between fluoroscopic images and the reference 4DCT template: un-normalized cross-correlation (CC), normalized cross-correlation (NCC) and normalized mutual information (NMI), as well as average intensity (AI) of the region of interest (ROI) in the fluoroscopic images. Performance was evaluated using fluoroscopic and 4DCT data from three lung cancer patients. On average, gating based on CC achieves the highest treatment accuracy given the same efficiency, with a high target coverage (average between 91.9% and 98.6%) for a wide range of nominal duty cycles (20-50%). AI works well for two patients out of three, but failed for the third patient due to interference from the heart. Gating based on NCC and NMI usually failed below 50% nominal duty cycle. Based on this preliminary study with three patients, we found that the proposed CC-based gating algorithm can generate accurate and robust gating signals when using 4DCT reference template. However, this observation is based on results obtained from a very limited

    Child abuse pediatricians have multiple roles in caring for abused children, including prevention, diagnosis, treatment, and, when needed, expert legal opinion. The child physical abuse consultation differs from the traditional medical consultation in that it has medical, investigative and legal audiences, all of whom have different information needs. How child abuse pediatricians approach their cases and how they document their initial inpatient consultations that will be used by such a diverse audience is currently unexplored. We used content analysis to examine 37 child physical abuse consultation notes from a national sample of child abuse pediatricians in order to understand physicians' approaches to these consultations. Three commonly used models of child physical abuse consultation were identified in the data that we named the base model, the investigative model, and the family-dynamic model. While model types overlap, each is distinguished by key features including the approach used to gather information, the information recorded, and the language used in documentation. The base model most closely mirrors the traditional medical approach; the investigative model concentrates on triangulation of sources of information; and, the family-dynamic model concentrates on physician perceptions of family relationships. The three models of consultations for child physical abuse mirror the areas of child abuse pediatrics: diagnostic, forensic and therapeutic. These models are considered in relationship to best practice from other medical specialties with forensic components.

    In extreme situations of massive projective identification, both the analyst and the patient may come to share a fantasy or belief that his or her own psychic reality will be annihilated if the psychic reality of the other is accepted or adopted (Britton 1998). In the example of' Dr. M and his patient, the paradoxical dilemma around note taking had highly specific transference meanings; it was not simply an instance of the generalized human response of distracted attention that Freud (1912) had spoken of, nor was it the destabilization of analytic functioning that I tried to describe in my work with Mr. L. Whether such meanings will always exist in these situations remains a matter to be determined by further clinical experience. In reopening a dialogue about note taking during sessions, I have attempted to move the discussion away from categorical injunctions about what analysis should or should not do, and instead to foster a more nuanced, dynamic, and pair-specific consideration of the analyst's functioning in the immediate context of the analytic relationship. There is, of course, a wide variety of listening styles among analysts, and each analyst's mental functioning may be affected differently by each patient whom the analyst sees. I have raised many questions in the hopes of stimulating an expanded discussion that will allow us to share our experiences and perhaps reach additional conclusions. Further consideration may lead us to decide whether note taking may have very different meanings for other analysts and analyst-patient pairs, and whether it may serve useful functions in addition to the one that I have described.

    2014-05-30

    Since its introduction in plants 10 years ago, the bimolecular fluorescence complementation (BiFC) method, or split-YFP (yellow fluorescent protein), has gained popularity within the plant biology field as a method to study protein-protein interactions. BiFC is based on the restoration of fluorescence after the two non-fluorescent halves of a fluorescent protein are brought together by a protein-protein interaction event. The major drawback of BiFC is that the fluorescent protein halves are prone to self-assembly independent of a protein-protein interaction event. To circumvent this problem, several modifications of the technique have been suggested, but these modifications have not lead to improvements in plant BiFC protocols. Therefore, it remains crucial to include appropriate internal controls. Our literature survey of recent BiFC studies in plants shows that most studies use inappropriate controls, and a qualitative rather than quantitative read-out of fluorescence. Therefore, we provide a cautionary note and beginner's guideline for the setup of BiFC experiments, discussing each step of the protocol, including vector choice, plant expression systems, negative controls, and signal detection. In addition, we present our experience with BiFC with respect to self-assembly, peptide linkers, and incubation temperature. With this note, we aim to provide a guideline that will improve the quality of plant BiFC experiments.

    Background Full sharing of the electronic health record with patients has been identified as an important opportunity to engage patients in their health and health care. The My HealtheVet Pilot, the initial personal health record of the US Department of Veterans Affairs, allowed patients and their delegates to view and download content in their electronic health record, including clinical notes, laboratory tests, and imaging reports. Objective A qualitative study with purposeful sampling sought to examine patients’ views and experiences with reading their health records, including their clinical notes, online. Methods Five focus group sessions were conducted with patients and family members who enrolled in the My HealtheVet Pilot at the Portland Veterans Administration Medical Center, Oregon. A total of 30 patients enrolled in the My HealtheVet Pilot, and 6 family members who had accessed and viewed their electronic health records participated in the sessions. Results Four themes characterized patient experiences with reading the full complement of their health information. Patients felt that seeing their records positively affected communication with providers and the health system, enhanced knowledge of their health and improved self-care, and allowed for greater participation in the quality of their care such as follow-up of abnormal test results or decision-making on when to seek care. While some patients felt that seeing previously undisclosed information, derogatory language, or inconsistencies in their notes caused challenges, they overwhelmingly felt that having more, rather than less, of their health record information provided benefits. Conclusions Patients and their delegates had predominantly positive experiences with health record transparency and the open sharing of notes and test results. Viewing their records appears to empower patients and enhance their contributions to care, calling into question common provider concerns about the effect of full

    Based on the idea that electric light at night might account for a portion of the high and rising risk of breast cancer worldwide, it was predicted long ago that women working a non-day shift would be at higher risk compared with day-working women. This hypothesis has been extended more recently to prostate cancer. On the basis of limited human evidence and sufficient evidence in experimental animals, in 2007 the International Agency for Research on Cancer (IARC) classified 'shift work that involves circadian disruption' as a probable human carcinogen, group 2A. A limitation of the epidemiological studies carried out to date is in the definition of 'shift work.' IARC convened a workshop in April 2009 to consider how 'shift work' should be assessed and what domains of occupational history need to be quantified for more valid studies of shift work and cancer in the future. The working group identified several major domains of non-day shifts and shift schedules that should be captured in future studies: (1) shift system (start time of shift, number of hours per day, rotating or permanent, speed and direction of a rotating system, regular or irregular); (2) years on a particular non-day shift schedule (and cumulative exposure to the shift system over the subject's working life); and (3) shift intensity (time off between successive work days on the shift schedule). The group also recognised that for further domains to be identified, more research needs to be conducted on the impact of various shift schedules and routines on physiological and circadian rhythms of workers in real-world environments.

  11. Note: Studies on x-ray production in electron cyclotron resonance x-ray source based on ridged cylindrical cavity

    Selvakumaran, T. S.; Baskaran, R.

    2012-02-15

    A ridged cylindrical cavity has been designed using MICROWAVE STUDIO programme and it is used in the electron cyclotron resonance (ECR) x-ray source. The experimental parameters of the source are optimized for maximizing the x-ray output, and an x-ray dose rate of {approx}1000 {mu}Sv/h was observed at 20 cm from the port, for 500 W of microwave power without using any target. With the molybdenum target located at optimum position of the ridged cavity, the dose rate is found to be increased only by 10%. In order to understand the experimental observation, the electric field pattern of the cavity with the target placed at various radial distances is studied. In this note, the experimental and theoretical studies on ECR x-ray source using the ridged cylindrical cavity are presented.

    2012-06-01

    In these notes, we continue our investigation of classical toy models of disordered statistical mechanics, through techniques recently developed and tested mainly on the paradigmatic Sherrington-Kirkpatrick spin glass. Here, we consider the p-spin-glass model with Ising spins and interactions drawn from a normal distribution N[0,1]. After a general presentation of its properties (e.g., self-averaging of the free energy, existence of a suitable thermodynamic limit), we study its equilibrium behavior within the Hamilton-Jacobi framework and the smooth cavity approach. Through the former we find both the RS and the 1-RSB expressions for the free-energy, coupled with their self-consistent relations for the overlaps. Through the latter, we recover these results as irreducible expression, and we study the generalization of the overlap polynomial identities suitable for this model; a discussion on their deep connection with the structure of the internal energy and the entropy closes the investigation.

    Discreet collection of spot check observations to measure household hygiene conditions is a common measurement technique in epidemiologic studies of hygiene in low-income countries. The objective of this study was to determine whether the collection of spot check observations in longitudinal studies could itself induce reactivity (i.e., change participant behavior). We analyzed data from a 12-month prospective cohort study in rural Tamil Nadu, India that was conducted in the absence of any hygiene or toilet promotion activities. Our data included hygiene and toilet spot checks from 10,427 household visits. We found substantial evidence of participant reactivity to spot check observations of hygiene practices that were easy to modify on short notice. For example, soap observed at the household's primary handwashing location increased from 49% at enrollment to 81% by the fourth visit and remained at or above 77% for the remainder of the study.

    The scanning tunneling microscope (STM) is a powerful tool for studying the electronic properties at the atomic level, however, it is of relatively small scanning range and the fact that it can only operate on conducting samples prevents its application to study heterogeneous samples consisting of conducting and insulating regions. Here we present a long-range scanning tunneling microscope capable of detecting conducting micro and nanostructures on insulating substrates using a technique based on the capacitance between the tip and the sample and performing STM studies.

    2011-05-01

    This study examines the process by which child behavioral problems are related to parents' well-being. We developed a family-work spillover model that was tested among 225 working parents. It was hypothesized that family-self conflict (FSC) mediates the relationship between child behavioral problems and parental strain, and that family-work conflict (FWC) mediates the relationship between parental strain and work engagement. Further, it was hypothesized that social support moderates the relationship between child behavioral problems and FSC. The results of (moderated) structural equation modeling supported the mediating role of FSC and FWC and the moderating role of social support. These findings suggest that the negative effects of raising a child with behavioral problems on parental well-being can be buffered by social support.

    Remembered utility is the retrospective evaluation about the pleasure and pain associated with a past experience. It has been shown to influence prospective choices about whether to repeat or to avoid similar situations in the future (D. Kahneman 2000; D. Kahneman, D. L. Fredrickson, C. A. Schreiber, & D. A. Redelmeier, 1993). Evaluations about our hedonic past often disregard the duration of the experience and are influenced more by the peak and the final levels of discomfort (B. L. Fredrickson & D. Kahneman, 1993). Two experiments explored the remembered discomfort of an effortful learning experience and the influence of this evaluation on prospective study choices. The design of the studies mimicked D. Kahneman et al.'s (1993) cold-pressor study, but used an exceptionally challenging learning experience in place of the painful experience of submerging one's hand in ice water. An extremely effortful study episode extended by a more moderate interval was preferred to a shorter, unextended interval, despite better test performance following the shorter interval. Future study choices reflected this preference. These findings suggest that the act of acquiring knowledge has value in the learning process.

    A description of a stand based on atomic force microscopy (AFM) for roughness measurements of large optical components with arbitrary surfaces is given. The sample under study is mounted on a uniaxial goniometer which allows the sample to be tilted in the range of ±30°. The inclination enables the local normal along the axis of the probe to be established at any point of the surface under study. A comparison of the results of the measurement of noise and roughness of a flat quartz sample, in the range of spatial frequencies 0.025–70 μm{sup −1}, obtained from “standard” AFM and developed versions is given. Within the experimental error, the measurement results were equivalent. Examples of applications of the stand for the study of substrates for X-ray optics are presented.

  5. Note on the Applicability of the James-Stein Estimator in Regional Hydrologic Studies

    Landwehr, J. Maciunas; Matalas, N. C.; Wallis, J. R.

    1984-11-01

    The applicability of the James-Stein estimator in regional hydrologic studies which entail the estimation of an N-dimensional location parameter is discussed. Regional studies are frequently characterized by relatively short, generally correlated, samples drawn from nonsymmetric and bounded, i.e., nonnormal, populations. By means of computer simulation studies the James-Stein estimator, subject to the Lindley modification and adoption of the positive part rule suggested by Efron and Morris and conditioned on the assumption of independence, was shown to be robust in the case of the hydrologically plausible distribution considered here, namely, Weibull distributions with coefficient of skewness ranging from 0 to 10. However, in contrast to traditional methods of regionalization the effect of cross correlation is a diminishment of the relative risk advantage of the James-Stein estimator, even in the best case of normal variables : this is discussed and illustrated.

    Manganese (Mn) is a nutrient essential for regulating neurological and skeletal functions in the human body, but it is also toxic when humans are excessively exposed to Mn. Blood (or serum/plasma) and other body fluids reflect only the most recent exposure and rapidly return to within normal ranges, even when there has been a temporary excursion in response to exposure. In this context, we have been developing a non-invasive measurement of Mn stored in bone, using in vivo neutron activation analysis. Following feasibility studies, a first pilot study, using neutron activation analysis to measure Mn in the bones of the hand of ten healthy male human subjects, was conducted with the approval of the concerned research ethics boards. The participants of this study had no known history of exposure to Mn. Two volunteers were excluded from this study due to technical problems with their measurements. The inverse variance weighted mean value of Mn/Ca for the participants of this study is 0.12 ± 0.68 µg Mn/g Ca which is comparable within uncertainties with the estimated range of 0.16 0.78 µg Mn/g Ca and mean value of 0.63 ± 0.30 µg Mn/g Ca derived from cadaver data. It is recommended to investigate the use of the diagnostic technique for in vivo measurements of workers exposed occupationally to excessive amounts of Mn who could develop many-fold increased levels of Mn in bones as demonstrated through various animal studies. The technique needs further development to improve the precision of in vivo measurements in the non-exposed population.

    Aims: (1) To describe the prevalence of fatigue among employees in different work schedules (day work, three-shift, five-shift, and irregular shift work); (2) to investigate whether different work schedules are related to increasing fatigue over time, while taking into account job title and job characteristics; and (3) to study fatigue among shift workers changing to day work. Methods: Data from nine consecutive four-monthly self administered questionnaires from the Maastricht Cohort Study on Fatigue at work (n = 12 095) were used with 32 months of follow up. Day and shift workers were matched on job title. Results: The prevalence of fatigue was 18.1% in day workers, 28.6% in three-shift, 23.7% in five-shift, and 19.1% in irregular shift workers. For three-shift and five-shift workers substantial higher fatigue levels were observed compared to day workers at baseline measurement. In the course of fatigue over the 32 months of follow up there were only small and insignificant differences between employees in different work schedules. However, among employees fatigued at baseline, fatigue levels decreased faster over time among five-shift workers compared to fatigued day workers. Shift workers changing to day work reported substantially higher fatigue levels prior to change, compared to those remaining in shift work. Conclusions: Substantial differences in fatigue existed between day and shift workers. However, as no considerable differences in the course of fatigue were found, these differences have probably developed within a limited time span after starting in a shift work job. Further, evidence was found that fatigue could be an important reason for quitting shift work and moving to day work. Finally, in the relation between work schedules and fatigue, perceived job characteristics might play an important role. PMID:12782747

    The lidA Cohort Study (German Cohort Study on Work, Age, Health and Work Participation) was set up to investigate and follow the effects of work and work context on the physical and psychological health of the ageing workforce in Germany and subsequently on work participation. Cohort participants are initially employed people subject to social security contributions and born in either 1959 (n = 2909) or 1965 (n = 3676). They were personally interviewed in their homes in 2011 and will be visited every 3 years. Data collection comprises socio-demographic data, work and private exposures, work ability, work and work participation attitudes, health, health-related behaviour, personality and attitudinal indicators. Employment biographies are assessed using register data. Subjective health reports and physical strength measures are complemented by health insurance claims data, where permission was given. A conceptual framework has been developed for the lidA Cohort Study within which three confirmatory sub-models assess the interdependencies of work and health considering age, gender and socioeconomic status. The first set of the data will be available to the scientific community by 2015. Access will be given by the Research Data Centre of the German Federal Employment Agency at the Institute for Employment Research (http://fdz.iab.de/en.aspx).

    The introduction of strategic corporate sustainability policies is expected to result in the improvement of several issues in companies. One of these issues is work, which should involve greater well-being for workers. Within the context of production engineering, this research connects sustainability and work-related issues, the latter seen in light of the discipline of ergonomics. Based on case studies conducted at four companies considered sustainability benchmarks, we examined how the introduction of the theme of sustainability has influenced work-related issues. The elements analyzed here were the corporate sustainability strategy, organizational practices for deploying the strategy, and the work design phase. The last element is the moment in which work is prescribed in the organization. The results show that, despite the announcement of the inclusion of changes in work, there is not any explicit evidence confirming that such changes are considered as a requirement for corporate sustainability projects.

  5. NOTE: Study of Gafchromic® EBT film response over a large dose range

    NASA Astrophysics Data System (ADS)

    2010-05-01

    Presently Gafchromic EBT films are widely used for relative dose verification in standard radiation therapy using high-energy photons, inclusive IMRT. The use of films for dosimetry in medical ion beams is more complicated due to the strongly inhomogeneous dose deposition by ions on microscopic level. Track structure models, presently used to describe dosimeter response as a function of the ion field properties, are based on input information which can be obtained from the film response in photon beams. We therefore studied the performance of Gafchromic EBT films, ancestors of currently available EBT2 films, in 60Co photon beams. The dose-response curve was measured from 7.5 × 10-2 Gy to 3 × 104 Gy. The dynamic range, linearity and dose rate dependence of this calibration curve were studied. A high saturation dose of 3 × 103 Gy, and thus a large dynamic range, was observed. No signs of supralinearity and bleaching due to radiation were found. No dependence of the response on the dose rate at high dose rates and high doses was found. All those properties justify the use of simplified models of the film response to ions. Furthermore, fits of the calibration data by predictions of different models for signal creation mechanism of dosimetric materials were performed. The best description was found for the recently published gamma-distributed single-hit model which takes into account different sizes of the active centres.

    Radiation damage to the walls of reactor pressure vessels (RPVs) causes the steel to become more brittle and less able to withstand the thermal stresses of start-up and shut-down procedures. Current methods of monitoring the degree of embrittlement are based on measurements of the ductile-to-brittle transition temperature (DBTT) of surveillance specimens subjected to severe radiation damage inside the reactor itself. In order to improve on this conservative approach and extend the useful life of vessels that have been in service for many years, NIST undertook a feasibility study to investigate nondestructive techniques for inferring the DBTT of the pressure vessel wall itself. The approach used was based on the hypothesis that the changes in microstructure that accompany embrittlement could be detected by accurate measurements of the physical properties of the steel in the pressure vessel wall.

    Here, an upgrade of the pulsed magnetic field generator magneto-inertial fusion electrical discharge system [O. Gotchev et al., Rev. Sci. Instrum. 80, 043504 (2009)] is described. The device is used to study magnetized high-energy-density plasma and is capable of producing a pulsed magnetic field of tens of tesla in a volume of a few cubic centimeters. The magnetic field is created by discharging a high-voltage capacitor through a small wire-wound coil. The coil current pulse has a duration of about 1 μs and a peak value of 40 kA. Compared to the original, the updated version has a larger energy storage and improved switching system. In addition, magnetic coils are fabricated using 3-D printing technology which allows for a greater variety of the magnetic field topology.

    Equilibrium partitioning (EqP) studies on bioaccumulation of organic chemicals in aquatic organisms typically require long-term exposures. In the case of highly hydrophobic neutral organic chemicals, such as polychiorinated biphenyls (PCBs), dioxins, and dibenzofurans, exposures of up to 6 months have been used (Pruell and others 1990). During long-term laboratory exposures, changes can occur in the condition of both organism and sediment. Sediments can be depleted of the bioavailable fraction of chemical, thereby reducing exposure. Nutrient quality and amount may decline and sublethal toxicity may occur, affecting the health of organisms and causing loss of lipids. Metabolic degradation of bioaccumulating chemicals may occur in long-term exposures, reducing bioaccumulation. Induction of metabolizing enzymes caused by the chemical under investigation or by other chemicals in the sediment may exacerbate this effect. Growth during the exposure period can dilute tissue concentrations causing reduced apparent bioaccumulation. Spawning and other seasonal changes also affect bioaccumulation (Lee and others 1989).

    In the process of studying charge holding capability and delay time for breakdown in liquids under nanosecond (ns) time scales, a Tesla based pulse generator has been developed. Pulse generator is a combination of Tesla transformer, pulse forming line, a fast closing switch, and test chamber. Use of Tesla transformer over conventional Marx generators makes the pulse generator very compact, cost effective, and requires less maintenance. The system has been designed and developed to deliver maximum output voltage of 300 kV and rise time of the order of tens of nanoseconds. The paper deals with the system design parameters, breakdown test procedure, and various experimental results. To validate the pulse generator performance, experimental results have been compared with PSPICE simulation software and are in good agreement with simulation results.

    We describe the design and implementation of a multi channel Doppler tuned spectrometer setup to study physics of highly charged ions at high resolution in a direct way. A unique Soller slit assembly coupled with a long one dimensional position sensitive proportional counter enables us to get distinct x-ray peaks at different angles, which allows us to cover large number of angle in one shot. By using this setup, 1s2s (3)S1 - 1s(2) (1)S0 M1 transition in He-like Fe has been resolved from its satellite line 1s2s2p ⁴P(5/2)⁰ - 1s(2)2s (2)S(1/2) M2 transition in Li-like Fe and measured the lifetime of their respective upper levels with high precision.

  15. Does work affect personality? A study in horses.

    It has been repeatedly hypothesized that job characteristics are related to changes in personality in humans, but often personality models still omit effects of life experience. Demonstrating reciprocal relationships between personality and work remains a challenge though, as in humans, many other influential factors may interfere. This study investigates this relationship by comparing the emotional reactivity of horses that differed only by their type of work. Horses are remarkable animal models to investigate this question as they share with humans working activities and their potential difficulties, such as "interpersonal" conflicts or "suppressed emotions". An earlier study showed that different types of work could be associated with different chronic behavioural disorders. Here, we hypothesised that type of work would affect horses' personality. Therefore over one hundred adult horses, differing only by their work characteristics were presented standardised behavioural tests. Subjects lived under the same conditions (same housing, same food), were of the same sex (geldings), and mostly one of two breeds, and had not been genetically selected for their current type of work. This is to our knowledge the first time that a direct relationship between type of work and personality traits has been investigated. Our results show that horses from different types of work differ not as much in their overall emotional levels as in the ways they express emotions (i.e. behavioural profile). Extremes were dressage horses, which presented the highest excitation components, and voltige horses, which were the quietest. The horses' type of work was decided by the stall managers, mostly on their jumping abilities, but unconscious choice based on individual behavioural characteristics cannot be totally excluded. Further research would require manipulating type of work. Our results nevertheless agree with reports on humans and suggest that more attention should be given to work

    Along with article-based checklists, structured template recording systems have been reported as useful to create more accurate clinical recording, but their contributions to the improvement of the quality of patient care have been controversial. An emergency department (ED) must manage many patients in a short time. Therefore, such a template might be especially useful, but few ED-based studies have examined such systems.A structured template produced according to widely used head injury guidelines was used by ED residents for head injury patients. The study was conducted by comparing each 6-month period before and after launching the system. The quality of the patient notes and factors recorded in the patient notes to support the head computed tomography (CT) performance were evaluated by medical students blinded to patient information.The subject patients were 188 and 177 in respective periods. The numbers of patient notes categorized as "CT indication cannot be determined" were significantly lower in the postintervention term (18% → 9.0%), which represents the patient note quality improvement. No difference was found in the rates of CT performance or CT skip without clearly recorded CT indication in the patient notes.The structured template functioned as a checklist to support residents in writing more appropriately recorded patient notes in the ED head injury patients. Such a template customized to each clinical condition can facilitate standardized patient management and can improve patient safety in the ED.

    Understanding the experiences of retired nurses can be useful in increasing self-confidence, motivation to work and work enthusiasm among nurses. The purpose of this study was to explore the work experiences of Iranian retired nurses. A qualitative design was conducted using a content analysis approach. Purposive sampling was used to choose the study participants. Semi-structured interviews were held to collect the perspectives of 20 retired nurses (10 female and 10 male). Two main themes emerged in the data analysis: 'work problems and unpleasant experiences in a sense' with subthemes 'exhausting work', 'insufficient salary', 'inappropriate relation' and 'unsuitable social position'; and 'job satisfaction and pleasant experiences in a sense' with subthemes 'divine satisfaction and religious belief', 'satisfaction of patients and their companions' and 'love of nursing profession and relaxation experience'. The findings indicate the challenges that nurses face after retirement. These experiences will help nurse managers to adopt appropriate measures to support nurses after retirement.

    Purpose: Magnetic fields are known to alter radiation dose deposition. Before patients receive treatment using an MRI-linear accelerator (MRI-Linac), preclinical studies are needed to understand the biological consequences of magnetic-field-induced dose effects. In the present study, the authors sought to identify a beam energy and magnetic field strength combination suitable for preclinical murine experiments. Methods: Magnetic field dose effects were simulated in a mouse lung phantom using various beam energies (225 kVp, 350 kVp, 662 keV [Cs-137], 2 MV, and 1.25 MeV [Co-60]) and magnetic field strengths (0.75, 1.5, and 3 T). The resulting dose distributions were compared with those in a simulated human lung phantom irradiated with a 6 or 8 MV beam and orthogonal 1.5 T magnetic field. Results: In the human lung phantom, the authors observed a dose increase of 45% and 54% at the soft-tissue-to-lung interface and a dose decrease of 41% and 48% at the lung-to-soft-tissue interface for the 6 and 8 MV beams, respectively. In the mouse simulations, the magnetic fields had no measurable effect on the 225 or 350 kVp dose distribution. The dose increases with the Cs-137 beam for the 0.75, 1.5, and 3 T magnetic fields were 9%, 29%, and 42%, respectively. The dose decreases were 9%, 21%, and 37%. For the 2 MV beam, the dose increases were 16%, 33%, and 31% and the dose decreases were 9%, 19%, and 30%. For the Co-60 beam, the dose increases were 19%, 54%, and 44%, and the dose decreases were 19%, 42%, and 40%. Conclusions: The magnetic field dose effects in the mouse phantom using a Cs-137, 3 T combination or a Co-60, 1.5 or 3 T combination most closely resemble those in simulated human treatments with a 6 MV, 1.5 T MRI-Linac. The effects with a Co-60, 1.5 T combination most closely resemble those in simulated human treatments with an 8 MV, 1.5 T MRI-Linac. PMID:26328998

    Stochastic modeling of rainfall data is an important area in meteorology. The gamma distribution is a widely used probability model for non-zero rainfall. Typically the choice of the distribution for such meteorological studies is based on two goodness-of-fit tests—the Pearson's Chi-square test and the Kolmogorov-Smirnov test. Inspired by the index of dispersion introduced by Fisher (Statistical methods for research workers. Hafner Publishing Company Inc., New York, 1925), Mooley (Mon Weather Rev 101:160-176, 1973) proposed the variance test as a goodness-of-fit measure in this context and a number of researchers have implemented it since then. We show that the asymptotic distribution of the test statistic for the variance test is generally not comparable to any central Chi-square distribution and hence the test is erroneous. We also describe a method for checking the validity of the asymptotic distribution for a class of distributions. We implement the erroneous test on some simulated, as well as real datasets and demonstrate how it leads to some wrong conclusions.

    Characterizing the technical precision of measurements is a necessary stage in the planning of experiments and in the formal sample size calculation for optimal design. Instruments that measure multiple analytes simultaneously, such as in high-throughput assays arising in biomedical research, pose particular challenges from a statistical perspective. The current most popular method for assessing precision of high-throughput assays is by scatterplotting data from technical replicates. Here, we question the statistical rationale of this approach from both an empirical and theoretical perspective, illustrating our discussion using four example data sets from different genomic platforms. We demonstrate that such scatterplots convey little statistical information of relevance and are potentially highly misleading. We present an alternative framework for assessing the precision of high-throughput assays and planning biomedical experiments. Our methods are based on repeatability-a long-established statistical quantity also known as the intraclass correlation coefficient. We provide guidance and software for estimation and visualization of repeatability of high-throughput assays, and for its incorporation into study design. © 2016 The Authors.

  5. Neuro-tracing approach to study kidney innervation: a technical note

    2017-01-01

    Neuro-tracing approach is a great option to study innervation of the visceral organs including the kidneys. Important factors contributing to the success of this technique include the choice of a neuro-tracer, and delivery methods to result in successful labeling of peripheral sensory and motor ganglia. The neuro-tracer is usually applied directly to the kidney accessed via a surgical opening of the abdominal wall under deep anesthesia. A series of local microinjections of the dye are performed followed by a wound closure, and recovery period from the surgery. An extra care should be taken to prevent neuro-tracer spillage and accidental labeling of the surrounding organs during injections of the dye. Retrograde neuro-tracers like Fast Blue do not cross synapses, therefore, only neuronal bodies located within dorsal root ganglion neurons and major peripheral ganglia will be labeled by this approach. Retrogradely labeled peripheral neurons could be freshly isolated and dissociated for electrophysiological recordings and biochemical analyses (gene and protein expression), whereas the whole fixed ganglia could be sectioned to undergo immunohisto- and immunocytochemical targeted staining.

    The purpose of this study was to estimate the scattered dose to thyroid from prophylactic cranial irradiation during childhood. The MCNP transport code and mathematical phantoms representing the average individual at ages 3, 5, 10, 15 and 18 years old were employed to simulate cranial radiotherapy using two lateral opposed fields. The mean radiation dose received by the thyroid gland was calculated. A 10 cm thick lead block placed on the patient's couch to shield the thyroid was simulated by MCNP code. The Monte Carlo model was validated by measuring the scattered dose to the unshielded and shielded thyroid using three different humanoid phantoms and thermoluminescense dosimetry. For a cranial dose of 18 Gy, the thyroid dose obtained by Monte Carlo calculations varied from 47 to 79 cGy depending upon the age of the child. Appropriate placement of the couch block resulted in a thyroid dose reduction by 39 to 54%. Thyroid dose values at all possible positions of the radiosensitive gland with respect to the inferior field edge at five different patient ages were found. The mean difference between Monte Carlo results and thyroid dose measurements was 9.6%.

    Paleohydrological data, sometimes called "proxy records," reveal features of hydrologic variability not amenable to study with short instrumental hydrologic time series. Included are low-frequency features at wavelengths longer than the instrumental record, as well as high-frequency features that might differ in statistical properties from those that happen to be sampled by the instrumental record. Advances in paleohydrological methods and the expanded field collections of paleohydrologic proxies worldwide enable the reconstruction of different components of the hydrologic cycle on various scales of time and space. Reducing uncertainty about the variability of hydrologic processes is a major goal of paleohydrologic studies. New methods and datasets will help achieve this goal. At the same time, it is important to assess and appreciate the strengths and weaknesses of the expanding network of available proxy records.

    Nudging is an assimilation technique widely used in the development and evaluation of climate models. Con- straining the simulated wind and temperature fields using global weather reanalysis facilitates more straightforward comparison between simulation and observation, and reduces uncertainties associated with natural variabilities of the large-scale circulation. On the other hand, the artificial forcing introduced by nudging can be strong enough to change the basic characteristics of the model climate. In the paper we show that for the Community Atmosphere Model version 5, due to the systematic temperature bias in the standard model and the relatively strong sensitivity of homogeneous ice nucleation to aerosol concentration, nudging towards reanalysis results in substantial reductions in the ice cloud amount and the impact of anthropogenic aerosols on longwave cloud forcing. In order to reduce discrepancies between the nudged and unconstrained simulations and meanwhile take the advantages of nudging, two alternative experimentation methods are evaluated. The first one constrains only the horizontal winds. The second method nudges both winds and temperature, but replaces the long-term climatology of the reanalysis by that of the model. Results show that both methods lead to substantially improved agreement with the free-running model in terms of the top-of-atmosphere radiation budget and cloud ice amount. The wind-only nudging is more convenient to apply, and provides higher correlations of the wind fields, geopotential height and specific humidity between simulation and reanalysis. This suggests that nudging the horizontal winds but not temperature is a good strategy, especially for studies that involve both warm and cold clouds.

    Background Studies of the nursing work environment are increasingly common in developed countries, but few exist in developing countries. Because of resource differences between the two contexts, researchers need to clarify what aspects of the work environments are similar and different. Objectives To study the perspectives of Mexican nurses about their work environments to determine similarities and differences to results from developed world studies. Design A secondary, directed content analysis of qualitative data from 46 Spanish language interviews using workplace-oriented themes Setting Purposively selected Mexican states from four regions of the country that reflect the country’s socioeconomic differences. Participants Practicing Mexican nurses with at least one year of clinical experience and currently working in nursing. Participants were recruited through convenience and snowball sampling techniques. Methods Initial data collection occurred in 2006 and 2008 during a broader study about professionalization processes that occurred in Mexican nursing between 1980 and 2005. The secondary, directed content analysis focused on an in-depth exploration of a central theme that emerged from the two original studies: The Workplace. The directed content analysis used themes from the global nursing work environment literature to structure the analysis: Professional relationships, organizational administrative practices, and quality of care and services. Results The three themes from the global literature were relevant for the Mexican context and a new one emerged related to hiring practices. By category, the same factors that created positive or negative perceptions of the work environment matched findings from other international studies conducted in developed countries. The descriptors of the category, however, had different conceptual meanings that illustrate the health system challenges in Mexico. Conclusions Findings from this study suggest that studies that

    The responses of broilers to increments of dietary P concentration in P retention and P prececal digestibility were studied in 2 experiments using Ross 308 broilers in their fourth week of age. The low-P basal diet was mainly based on corn, potato protein, and corn starch. Titanium dioxide was used as the indigestible marker. Monobasic calcium phosphate was added in 6 (experiment 1) or 5 (experiment 2) graded levels up to a maximum of 8.1 g of P/kg of the diet. Five (experiment 1) and 6 (experiment 2) replicated pens of 10 birds were used. Excreta were collected from trays underneath the pens. Birds were asphyxiated by carbon dioxide exposure and the ileum (from Meckel's diverticulum to 2-cm anterior to the ileo-ceca-colonic junction) was dissected. Digesta was collected from the entire section (experiment 1) or from 3 subsections of equal lengths (experiment 2). Excretion of P increased linearly with increasing dietary P concentration up to a level of about 5.2 g of P/kg of the diet and increased nonlinearly with further increase in dietary P. In contrast, P flow in the ileum increased linearly over the entire range of P intake. Up to the level of 5.2 g of P/kg of the diet, P excretion was slightly lower than P flow in the ileum, but responses in P excretion and P flow in the ileum were similar, suggesting that P excretion with urine is very low and unaffected by P intake when the birds are supplied with P below their requirement. Between the 3 subsections of the ileum, calculated digestibility was significantly different for the basal diet and the diet with the 3 lowest levels of P supplementation. We concluded that the response in P prececal digestibility to increments in dietary P concentration is linear over a wider range of dietary P than the response in P retention. When digesta is collected from the ileum for determination of P prececal digestibility, the first third of the ileum should not be considered.

According to various studies, one of the factors influencing clinical competence is work experience. This experience affects the integrity of students' learning experience and their practical skills. Many nursing students practice clinical work during their full-time studying. The aim of this qualitative research was to clarify the role of clinical work during studying in novice nurses' clinical competence. Methods: This qualitative content analysis performed with the conventional approach. All teaching hospitals of Hormozgan University of Medical Sciences selected as the research environment. To collect data, deep and semi-structured interviews, presence in the scene and manuscripts used. To provide feedback for the next release and the capacity of the data, interviews were transcribed verbatim immediately. Results: 45 newly-graduated nurses and head nurses between 23 and 40 with 1 to 18 years of experience participated in the study. After coding all interviews, 1250 original codes were derived. The themes extracted included: task rearing, personality rearing, knowledge rearing, and profession rearing roles of clinical work during studying. Conclusion: Working during studying can affect performance, personality, knowledge, and professional perspectives of novice nurses. Given the differences that may exist in clinical competencies of novice nurses with and without clinical work experience, it is important to pay more attention to this issue and emphasize on their learning in this period.

  14. Note on numerical study of the beam energy spread in NDCX-I

    The kinetic energy spread (defined here as the standard deviation of the beam particle energies) sets the ultimate theoretical limit on the longitudinal compression that can be attained on NDCX-I and NDCX-II. Experimental measurements will inevitably include the real influences on the longitudinal phase space of the beam due to injector and accelerator field imperfections1. These induced energy variations may be the real limit to the longitudinal compression in an accelerator. We report on a numerical investigation of the energy spread evolution in NDCX-I; these studies do not include all the real imperfections, but rather are intended to confirm that there are no other intrinsic mechanisms (translaminar effects, transverse-longitudinal anisotropy instability, etc.) for significant broadening of the energy distribution. We have performed Warp simulations that use a realistic Marx voltage waveform which was derived from experimental measurements (averaged over several shots), a fully-featured model of the accelerating and focusing lattice, and new diagnostics for computing the local energy spread (and temperature) that properly account for linear correlations that arise from the discrete binning along each physical dimension (these capabilities reproduce and extend those of the earlier HIF code BPIC). The new diagnostics allow for the calculation of multi-dimensional maps of energy spread and temperature in 2-D axisymmetric or 3-D Cartesian space at selected times. The simulated beam-line was terminated at z = 3 m by a conducting plate, so as to approximately reproduce the experimental conditions at the entrance of the spectrometer that was used for mapping the longitudinal phase space. Snapshots of the beam projection and current, as well as the Marx waveform and history of beam kinetic energy collected at the end plate, are shown in Fig. 1. A two-dimensional axisymmetric map of energy spread from simulations of a typical NDCX-I configuration is shown in Fig. 2 (a

    The study examined impacts of changing Orbiter cabin pressure and EMU EVA pressure to eliminate pure O2 prebreathing prior to EVA. The investigation defines circumscribing physiological boundaries and identifies changes required within Orbiter to reduce cabin pressure. The study also identifies payload impacts, payload flight assignment constraints, and impacts upon EMU resulting from raising EVA pressure. The study presents the trade-off which optimizes the choice of reduced cabin pressure and increased EVA pressure.

    2017-03-01

    'Work compatibility' (WC) is a multi-dimensional diagnostic tool for measuring human performance that affects safety performance of work force. There are a dearth of literature on the use of WC in industrial applications. In this study, the status of WC and its components across employees' demographics such as age, experience, designation and location of work were examined in a steel plant in India. Data on 119 employees collected using Demand-Energizer Instrument was analysed. The results revealed that supervisors perceive higher energizers, higher demands and low WC as compared to workers. Older and high experience employees perceive higher energizers, lower demands and high WC as compared to younger and less experienced employees. All employee groups perceive higher demand for physical environment and physical task content. The problematic work groups identified are less experienced employees and workers in 'allied sections'. The outcomes of the study help the management in three ways to improve human performance at work places: (i) it provides useful information about the work factors to be considered for intervention design, (ii) it identifies the work groups to be targeted while preparing intervention strategies and (iii) it can be used as a leading indicator of human performance.

    As yet no qualitative research studies looking at return to work following burns have been published. The aim of this study was to investigate the "hows" and "whys" of return to work, by purposively selecting a cross-section of burns patients who returned to the same/similar job, those who returned to work but either on a part-time basis or in a different role/job and those who became or remained unemployed, and using semi-structured interviews to explore their experiences. Using matrix analysis methodology, and with the general themes that emerged from these transcripts, it was possible to place patients into 5 broad groups, the "defeated", the "burdened", the "affected", the "unchanged" and the "stronger". We anticipate that use of these general groups will be useful in targeting multi-disciplinary return to work strategies, and discuss how this qualitative research has changed practice at the Queen Victoria Hospital Burns Centre.

  4. Developing a communication skills training program for pharmacists working in Southern African HIV/AIDS contexts: some notes on process and challenges.

    PubMed

    Watermeyer, Jennifer

    2011-10-01

    In an attempt to understand why patients do not take medications, researchers are increasingly focusing on how communication processes influence adherence behaviors. Pharmacists have an important role to play in this regard. However, existing communication skills training (CST) programs for pharmacists are not necessarily sensitive to the needs of pharmacists working in specific contexts such as Southern Africa. In addition, CST programs are often poorly described in the literature, lack a theoretical background, and focus excessively on evaluation. This article describes the process of developing a CST program for pharmacists working in Southern African HIV/AIDS contexts, focusing on conceptualization and design. Some shortfalls in current approaches to CST are addressed. A number of sources were consulted during the development phase of the project, including interactional and focus group research, previously developed training models, analysis of currently available CST materials for pharmacists, and a literature review. These are discussed and some attention is also given to the challenges of implementing and evaluating the program. The project highlights the importance of providing CST that is disease- and context-specific, grounded in appropriate research and theoretical frameworks, and based on a rigorous process of development.

    This study longitudinally compared activity in the frontal cortex during a spatial working memory task between 5-year-old and 7-year-old children using near-infrared spectroscopy. Eight children participated in this study twice, once at 5 years and once at 7 years of age. Behavioral analysis showed that older children performed the working memory task more precisely and more rapidly than younger children. Near-infrared spectroscopy analysis showed that right hemisphere dominance was observed in older children, whereas no hemispheric difference was apparent in younger children. Children with strengthened lateralization showed improved performance from 5 to 7 years. We therefore offer the first demonstration of the developmental changes in frontal cortical activation during spatial working memory tasks during the preschool period.

    2015-01-01

    Grit, defined as perseverance of effort and consistency of interest, has attracted attention as a predictor of success in various fields beyond IQ and the Big Five personality dimension of Conscientiousness. The purpose of the current study was to examine previously uninvestigated questions regarding grit using a cross-sectional design among a large number of working adults in Japan. First, we tested geographical generalizability of associations between grit and orientations towards happiness by comparing previous studies in the U.S. and the current study in Japan. It was confirmed that orientation towards meaning rather than orientation towards engagement had a stronger positive correlation with grit in our sample of Japanese people. This result is inconsistent with previous studies in the U.S. Furthermore, the Big Five dimension of Openness to Experience was newly confirmed as having a positive association with grit. Second, we examined the association between grit and work engagement, which is considered as an outcome indicator for work performance. In this analysis, grit was a strong predictor for work performance as well as academic performance. PMID:26335001

    Oñate, Esteban; Meyer, Felipe

    2012-01-01

    This study was part of an ergonomic program which is being carried out through an agreement between the University of Concepción and a Chilean private mining company. The purpose of this case study was to identify working conditions in which the physical and mental workload could be over the capabilities of the operator. He was responsible for loading trucks with sacks of molybdenum and for downloading reagents and handles them. The methods employed in this study included electronic records, interviews, surveys, review of the company standards, a time study and physical and mental workload analysis. Results showed that 84% of the time the operator was carrying out principal and secondary activities and no break periods were detected. It was found that the pace of work and the shift system generated unfavorable conditions by imbalance in the workload on the different days of the week. In the light of the results recommendations were made for a number of ergonomic changes. Most of them were accepted by the company. The most important achievement was a change in the shift system. The overload of the operator was due to the fact that he was in a shift working 5 days and resting on weekends. The imbalance was mainly because the work of the week end was accumulated for Monday. As a result of the study, the company contracted a second worker for this job and adopted a 7x7 shift system, meaning that they work seven days and rest seven days. An evaluation carried out two month after adopting the new shift revealed that changes were well accepted by the worker.

    International students' medical training often includes an elective placement in their home country to prepare them for practice on graduation. Seven Malaysian students in their final year of medicine were interviewed pre- and post-graduation and asked to reflect on whether they felt adequately prepared for working in Malaysia. These seven international students, who studied medicine in Australia, all returned to Malaysia for six weeks for their elective, and the interviews canvassed their perceptions of this experience, along with their thoughts on how well their training in Australia had prepared them for working in their country of origin. The interview data were qualitatively analysed, and case studies were constructed. Main themes were identified and tabulated. Students voiced similar concerns about how ready they were for working at home. These included a lack of practical skills relative to their Malaysian-trained counterparts, language difficulties, medical communication skill incompatibilities across cultures, expectations to perform complex or unfamiliar tasks with minimal supervision and substantial burdens of responsibility with long working hours. These students did not feel greatly prepared for their return home to practise medicine. The elective placement was not well utilized by the majority of students in this study.

  8. NOTE: Does the option to rotate the Elekta Beam Modulator MLC during VMAT IMRT delivery confer advantage?—a study of 'parked gaps'

    NASA Astrophysics Data System (ADS)

    Webb, S.

    2010-06-01

    When delivering intensity-modulated radiation therapy (IMRT) using the volumetric modulated arc therapy (VMAT) technique on an Elekta accelerator equipped with the Elekta Beam Modulator multileaf collimator (MLC), the orientation of the MLC, relative to the accelerator head, is generally fixed during the delivery. However, it has the ability to rotate about its axis as the gantry simultaneously rotates. This note shows that this can confer a potential advantage when planning and delivering IMRT via VMAT. A computer model has been built in which the MLC rotation angle could be varied with each control point (gantry location) within the constraints of the specified MLC rotation speed and the time available for rotation. The model was used to optimize the orientation trajectory in such a way as to minimize the number of parked gaps between leaves which are needed for some gantry orientations but not for others (and which cannot reach the shielding safety of surrounding jaws in the time available). The presented work started with the simple situation of collimating gantry-successive single convex shapes. As a broad statement some 40% reduction in such parked gaps could be achieved. The study was then extended to investigate the optimized trajectories for multiple separate concave shapes with, once again, a saving in unwanted parked gaps or unwanted over-irradiation.

  9. Barriers to Partnership Working in Public Health: A Qualitative Study

    PubMed Central

    Taylor-Robinson, David Carlton; Lloyd-Williams, Ffion; Orton, Lois; Moonan, May; O'Flaherty, Martin; Capewell, Simon

    2012-01-01

    Background Public health provision in England is undergoing dramatic changes. Currently established partnerships are thus likely to be significantly disrupted by the radical reforms outlined in the Public Health White Paper. We therefore explored the process of partnership working in public health, in order to better understand the potential opportunities and threats associated with the proposed changes. Methodology/Principal Findings 70 participants took part in an in-depth qualitative study involving 40 semi-structured interviews and three focus group discussions. Participants were senior and middle grade public health decision makers working in Primary Care Trusts, Local Authorities, Department of Health, academia, General Practice and Hospital Trusts and the third sector in England. Despite mature arrangements for partnership working in many areas, and much support for joint working in principle, many important barriers exist. These include cultural issues such as a lack of shared values and language, the inherent complexity of intersectoral collaboration for public health, and macro issues including political and resource constraints. There is particular uncertainty and anxiety about the future of joint working relating to the availability and distribution of scarce and diminishing financial resources. There is also the concern that existing effective collaborative networks may be completely disrupted as the proposed changes unfold. The extent to which the proposed reforms might mitigate or potentiate these issues remains unclear. However the threats currently remain more salient than opportunities. Conclusions The current re-organisation of public health offers real opportunity to address some of the barriers to partnership working identified in this study. However, significant threats exist. These include the breakup of established networks, and the risk of cost cutting on effective public health interventions. PMID:22238619

  10. [Work and family in the sociodemographic study of Mexico].

    PubMed

    Garcia, B; De Oliveira, O

    1991-06-01

    This work reviews sociodemographic studies of the interrelationship between work and family in Mexico from 1950 to the present. 3 main themes are distinguished and examined in separate sections. The 1st are labor market studies focusing on aggregates of individuals, a trend most prominent through the mid 1970s but still somewhat in evidence. The 2nd type of studies stress the household or domestic unit as the relevant unit of analysis and often conceptualize economic participation as part of the family life strategy or survival strategy. This perspective reached its maximum development in the late 1970s and early 1980s but also still appears. The last type of study stresses the increasing heterogeneity of labor markets related to the increase in nonsalaried employment and increasing female employment. The domestic unit is present as a determinant of family-based economic activity and female employment, but differences and conflicts between generations within the household are stressed. This perspective began to gain importance in the mid-1980s. The objective of the differentiation into 3 periods and types of study is to analyze changes in theoretical elements considered, principal thematic contents, methodological tools utilized, and results. The work is based on a selective review of literature considered representative. On the theoretical level, relations between work and family are now perceived as more complex and incorporate more elements of social reality than they did in the earlier studies. Most studies of this type have concerned female employment. The belief that male employment depends less on the family context requires reassessment, especially in view of the differential employment opportunities of men and women. Quantitative sociodemographic research in Mexico has been greatly aided by the growing availability of detailed survey data. This, together with advances in statistics and computation, has allowed a greater use of multivariate analysis to

    Abstract Objective: to evaluate the work ability and health status of security guards at a public University. Methods: a cross-sectional, descriptive, and analytical study was carried with 119 security guards. The following instruments were used: Work Ability Index (WAI), Patient Health Questionnaire (PHQ-9), International Physical Activity Questionnaire (IPAQ, short), Alcohol Use Disorders Identification Test (AUDIT), Medical Outcomes Study (MOS), and Demand-Control-Support (DCS). Descriptive statistics were used to describe the study samples and the Spearman's coefficient correlation was performed to assess the WAI. Significance level was set at 5%. Results: samples were composed by men; the mean age was 54.9 years (SD=5.7); 80% had partners, and 75% had basic education. The majority (95%) had only one job, the average length of service was 24.8 years (SD=11), ranging from 3 to 43 years. 88.9% worked ≤40 hours and 75% did not work at night shift or rotating shifts. The average score given to work ability was good (40.7 points), with significant correlation to social support at work (p-value=0.002), health conditions (p-value=0.094), and depression symptoms (p-value=0.054). Conclusion: this study showed that many characteristics might affect the work ability scores. Considering the results, we note that healthy life habits and a reorganization of work environments should be encouraged. PMID:27463107

  16. Case studies in working memory: a case for single cases?

    Patterns of cognitive deficit in single neuropsychological cases are common sources of evidence for theories of normal cognition. In particular, the working memory model has benefited from data obtained from a number of contrasting patients, in some cases resulting in modifications of the working memory model. In this paper, patterns of data from short-term memory patients and anarthric patients are compared with patterns of data from normal subjects. The patterns of patient data that were unlike those patterns typically found for groups of normal subjects, could be incorporated within a modified version of the articulatory loop component of the working memory model. However a small number of individual normal subjects also did not show the pattern that is reported on the basis of average performance of groups of normal subjects. This causes some difficulty in interpreting those data from such 'aberrant normal' patterns, and those data from single patients with functional cognitive deficits. The implications of these findings for the interpretation of neuropsychological data are discussed in the context of the working memory model, but with the intention of making a general point pertaining to the development of functional models of cognition. It is argued that single case studies should continue to provide a useful source of evidence, providing that care is exercised in considering the implications of such data for models of normal cognition.

    Aims: To evaluate the effect of implementation of an evidence based skin care programme for wet work employees as part of an occupational health and safety management system. Methods: 375 wet work employees were included in a prospective randomised controlled trial, allocated to either intervention (n = 207) or control (n = 168). The intervention group was exposed to a skin care programme during the five month study period. The intervention included an educational programme for a group of frontline employees, who underwent formalised training, and subsequently introduced the information to their colleagues. As part of the intervention a skin care policy including written instructions was established at each workplace. Both groups answered a test quiz, completed questionnaires on behaviour and symptoms, and underwent clinical examination of their hands before and after the five month period. Results: No difference between the intervention and the control group was found at baseline with respect to clinical symptoms or behaviour. Evaluation after the five months of intervention revealed a significantly higher information level on skin care in the intervention group compared to the control group, a significant change in behaviour in the intervention group but not in the control group, and significantly less skin symptoms as evaluated clinically in the intervention group but not in the control group. No significant difference was found for self reported skin problems. Conclusions: The intervention was successful with respect to information level (knowledge), behaviour, and clinical symptoms. Implementation of a skin care programme as part of an occupational health and safety management system is recommended as a prophylactic measure for employees in wet occupations. PMID:12151613

    Case studies are widely used as a teaching strategy for a variety of topics in various disciplines. They are particularly valued as a teaching strategy in the teaching of ethics because they provide a context for understanding the complexities of situations involving ethical dilemmas. This article describes the successful use of two literary works as case studies in teaching master's students about the ethical issues in human experimentation. Pygmalion and Flowers for Algernon were selected to exemplify the ethical considerations important in the conduct of research with human subjects. Students found the assignment both personally and professionally stimulating and recommended continued use of the assignment in the course.

    The objective of this study was to assess components, subscales, and interactions proposed by the popular Job Demand-Control (JDC), Job Demand-Control-Support (JDCS), and Effort-Reward Imbalance (ERI) work stress models in relation to diurnal variation of the stress hormone cortisol. Participants included 401 day-shift workers employed from a random sampling of 34 Canadian workplaces. Questionnaires included the Job Content Questionnaire to measure psychological demands, decision latitude, and social support as well as the Effort-Reward Imbalance Questionnaire to measure effort, reward, and overcommitment. Salivary cortisol was collected on 2 working days at awaking, +30 min after awaking, 1400h, 1600h, and bedtime. Multilevel regressions with 3 levels (time of day, workers, workplaces) were performed. Results revealed that JDC, JDCS and ERI interactions were not statistically associated with variations in diurnal cortisol concentrations. By contrast when assessing specific work stress subscales, increased psychological demands were linked to decreased bedtime cortisol, increased job recognition was linked to increased cortisol +30 min after waking and at bedtime, and finally increased overcommitment was linked to increased awakening cortisol and decreased cortisol at 1400h, 1600h, and bedtime. Sex moderation effects principally among men were additionally detected for psychological demands, total social support, and supervisor support. Our findings suggest that components and subsubscales of these popular work stress models rather than theorized interactions are more meaningful in explaining diurnal cortisol variations. In particular, psychological demands, job recognition, overcommitment, and to a lesser extent social support at work are the most significant predictors of diurnal cortisol variation in this large sample of Canadian workers. Importantly, the overall effect sizes of these subscales that explained diurnal cortisol concentrations were weak.

    The authors conducted a work-related stress surveillance study in 2013 on 6,558 public-sector employees in Italy, examining how they perceived their jobs, via the Job Content Questionnaire, and their mental health status, via the General Health Questionnaire 12 (GHQ-12). Of the 2,094 employees completing the questionnaires, 60% were male, 52% had a medium-level education, and 76% had a medium-level job. Three hundred and eighty-five employees (18%) had a GHQ-12 score >3 and were classified as GHQ-12 cases: these were more often female (54%), medium-to-highly educated (54%), and had more often reported health problems over the previous year (51%). Thus, GHQ-12 cases represented a significant percentage of the examined population, indicating that work-related stress surveillance programs are needed for the planning of psychosocial interventions aimed at the reintegration of individuals with mental health problems.

    Coagulase-negative staphylococci (CNS) are a group of bacteria classified as either minor mastitis pathogens or commensal microbiota. Recent research suggests species- and even strain-related epidemiological and genetic differences within the large CNS group. The current pilot study investigated in 2 experiments whether a mouse mastitis model validated for bovine Staphylococcus aureus can be used to explore further differences between CNS species and strains. In a first dose titration experiment, a low inoculum dose of S. aureus Newbould 305 (positive control) was compared with increasing inoculum doses of a Staphylococcus chromogenes strain originating from a chronic bovine intramammary infection to a sham-inoculated mammary glands (negative control). In contrast to the high bacterial growth following inoculation with S. aureus, S. chromogenes was retrieved in very low levels at 24 h postinduction (p.i.). In a second experiment, the inflammation inflicted by 3 CNS strains was studied in mice. The host immune response induced by the S. chromogenes intramammary strain was compared with the one induced by a Staphylococcus fleurettii strain originating from cow bedding sawdust and by a S. chromogenes strain originating from a teat apex of a heifer. As expected, at 28 and 48 h p.i., low bacterial growth and local neutrophil influx in the mammary gland were induced by all CNS strains. As hypothesized, bacterial growth p.i. was the lowest for S. fleurettii compared with that induced by the 2 S. chromogenes strains, and the overall immune response established by the 3 CNS strains was less pronounced compared with the one induced by S. aureus. Proinflammatory cytokine profiling revealed that S. aureus locally induced IL-6 and IL-1β but not TNF-α, whereas, overall, CNS-inoculated glands lacked a strong cytokine host response but also induced IL-1β locally. Compared with both other CNS strains, S. chromogenes from the teat apex inflicted a more variable IL-1β response

    Several countries have acknowledged the contributions made by national logistics working groups (NLWG) to ensure equitable access to the expanded program on immunization's (EPI) vaccines against preventable diseases. In order to provide key insights to the United Nations Children's Fund (UNICEF) and the World Health Organization (WHO) supply chain hub - as well as other players, including national EPI - a landscape analysis study was conducted from September 2015 to February 2016. This is a cross-sectional survey taken by 43 countries that combines qualitative and quantitative approaches. Data was collected through a desk review, consultation, interviews, and distance questioning. References and guidance were used to determine and specify the underlying mechanisms of NLWGs. The key findings are:This study has provided a general overview of the status of NLWGs for immunization in various countries. Based on the key insights of the study, technical assistance needs have been identified, and immunization partners will be required to help countries create and reinforce their NLWGs.

  7. Working with "rookies": A case study of science teachers mentors

    NASA Astrophysics Data System (ADS)

    Meagher, Thomas Francis

    To gain insight into the world of mentoring new science teachers it is imperative to examine how a veteran science teacher is influenced through his or her work mentoring a new teacher. The impacts of mentoring new teachers have been extensively researched within the literature, documenting many of the factors that may enhance the teaching abilities of new teachers (Hobson, Ashby, Malderez & Tomlinson, 2008; Ingersoll & Kralik, 2004; Wang & Odell, 2002). A thorough search of the literature reveals an unbalanced representation of research focusing on the many influences mentoring may bring to a new teacher while ignoring the impact on the mentor. It is when the activity of mentoring a new teacher is examined within the theoretical frame work of social cognitive learning, it is apparent that not only are two individuals participating in working together, but also that research needs to investigate both sides of the relationship. Also, since the mentoring relationship is situated within a community of practice, it becomes important to utilize a situated learning theoretical framework in tandem with social cognitive learning to provide the clearest picture of this dynamic social relationship. This case study seeks to share the impacts experienced by mentors through their work with new teachers and provide balance to the other side of research into the social partnership of mentoring. Five science teachers mentoring new teachers online, through the University of Minnesota's Science Engineering, Math Mentoring Program (STEMMP) and Science Teacher Induction Network (TIN), participated in this study that explores their experiences through a phenomenographic lens and follows an interpretive research approach. Four main themes emerged that identified how science teacher mentors were impacted from mentoring which included: (1) impacts to their teaching practice, (2) perceptions influenced from feedback, (3) enhanced reflection, and (4) enhancement of self-efficacy.

    This article introduces the theoretical and experimental case study of dynamic monitoring of the geological environment above constructed highway tunnel. The monitored structure is in this case a very important water supply pipeline, which crosses the tunnel and was made from steel tubes with a diameter of 800 mm. The basic dynamic parameters had been monitored during blasting works, and were compared with the FEM (Finite Element Method) calculations and checked by the Slovak standard limits. A calibrated FEM model based on the experimental measurement data results was created and used in order to receive more realistic results in further predictions, time and space extrapolations. This case study was required and demanded by the general contractor company and also by the owner of water pipeline, and it was an answer of public safety evaluation of risks during tunnel construction.

    The slope of the set size function as a critical statistic first gained favor in the 1960s due in large part to the seminal papers on short-term memory search by Saul Sternberg and soon, many others. In the 1980s, the slope statistic reemerged in much the same role in visual search as Anne Treisman and again, soon many others brought that research topic into great prominence. This note offers the historical and current perspective of the present author, who has devoted a significant portion of his theoretical efforts to this and related topics over the past 50 years.

    The lidA Cohort Study (German Cohort Study on Work, Age, Health and Work Participation) was set up to investigate and follow the effects of work and work context on the physical and psychological health of the ageing workforce in Germany and subsequently on work participation. Cohort participants are initially employed people subject to social security contributions and born in either 1959 (n = 2909) or 1965 (n = 3676). They were personally interviewed in their homes in 2011 and will be visited every 3 years. Data collection comprises socio-demographic data, work and private exposures, work ability, work and work participation attitudes, health, health-related behaviour, personality and attitudinal indicators. Employment biographies are assessed using register data. Subjective health reports and physical strength measures are complemented by health insurance claims data, where permission was given. A conceptual framework has been developed for the lidA Cohort Study within which three confirmatory sub-models assess the interdependencies of work and health considering age, gender and socioeconomic status. The first set of the data will be available to the scientific community by 2015. Access will be given by the Research Data Centre of the German Federal Employment Agency at the Institute for Employment Research (http://fdz.iab.de/en.aspx). PMID:24618186

    2016-01-01

    Objective Both working memory (WM) (a brain system that provides temporary storage and manipulation of the information) and attention-deficit/hyperactivity disorder (ADHD) have been associated with educational deficits. Since WM deficits are prevalent in children with ADHD, the main aim of the present study was to examine whether educational deficits are driven by working memory deficits or driven by the effect of ADHD itself. Method Participants were referred youth with (N=276) and without (N=241) ADHD ascertained from pediatric and psychiatric sources. Assessment included measures of psychiatric, psychosocial, educational, and cognitive functioning. Education deficits were defined as grade retention or placement in special classes, and were assessed using interviews and written rating scales. Working memory was assessed using the WISC-R Freedom from Distractibility (FFD) factor based on digit span, arithmetic and coding. Results Significantly more youth with ADHD had WM deficits than controls (31.9% vs. 13.7%, p< 0.05). In ADHD children, WM deficits were significantly (p<0.01) associated with an increased risk for grade retention and placement in special classes as well as lower scores on reading and math achievement tests, relative to ADHD children without WM deficits. In contrast, no other differences were noted in other areas of functioning. Although WM deficits also had some adverse impact on educational and cognitive correlates in non ADHD controls, these differences failed to attain statistical significance. Conclusion WM deficits significantly and selectively increase the risk for academic deficits and cognitive dysfunction in children with ADHD beyond those conferred by ADHD. Screening for WM deficits may help identify children with ADHD at high risk for academic and cognitive dysfunction. PMID:26902180

    2015-01-01

    We use the gender relations perspective from feminist theorizing to investigate how gender and daily emotion work predict daily relationship quality in 74 couples (148 individuals in dating, cohabiting, or married relationships) primarily from the southwest U.S. Emotion work is characterized by activities that enhance others’ emotional well-being. We examined emotion work two ways: trait (individuals’ average levels) and state (individuals’ daily fluctuations). We examined actor and partner effects of emotion work and tested for gender differences. As outcome variables, we included six types of daily relationship quality: love, commitment, satisfaction, closeness, ambivalence, and conflict. This approach allowed us to predict three aspects of relationship quality: average levels, daily fluctuations, and volatility (overall daily variability across a week). Three patterns emerged. First, emotion work predicted relationship quality in this diverse set of couples. Second, gender differences were minimal for fixed effects: Trait and state emotion work predicted higher average scores on, and positive daily increases in, individuals’ own positive relationship quality and lower average ambivalence. Third, gender differences were more robust for volatility: For partner effects, having a partner who reported higher average emotion work predicted lower volatility in love, satisfaction, and closeness for women versus greater volatility in love and commitment for men. Neither gender nor emotion work predicted average levels, daily fluctuations, or volatility in conflict. We discuss implications and future directions pertaining to the unique role of gender in understanding the associations between daily emotion work and volatility in daily relationship quality for relational partners.

This study is the first attempt to examine the longitudinal relationship between study addiction and work addiction. Methods The Bergen Study Addiction Scale (BStAS), the Bergen Work Addiction Scale (BWAS), and the Ten-Item Personality Inventory were administered online together with questions concerning demographics and study-related variables in two waves. In Wave 1, a total of 2,559 students in Norway and 2,177 students in Poland participated. A year later, in Wave 2, 379 Norwegians and 401 Polish who began to work professionally completed the survey. Results The intraclass correlation between BStAS and BWAS revealed that the scores were somewhat related; however, the relationship was slightly weaker than the temporal stability of both constructs. In the Norwegian sample, scoring higher on neuroticism and lower on learning time outside educational classes in Wave 1 was positively related to work addiction in Wave 2, whereas gender was unrelated to work addiction in Wave 2 when controlling for other studied variables in either samples. Conclusion Study addiction and work addiction appear to be closely related suggesting that the former may be a precursor for (or an early form of) the latter. PMID:27842448

  4. Technical Note: The impact of spatial scale in bias correction of climate model output for hydrologic impact studies

    NASA Astrophysics Data System (ADS)

    2016-02-01

    Statistical downscaling is a commonly used technique for translating large-scale climate model output to a scale appropriate for assessing impacts. To ensure downscaled meteorology can be used in climate impact studies, downscaling must correct biases in the large-scale signal. A simple and generally effective method for accommodating systematic biases in large-scale model output is quantile mapping, which has been applied to many variables and shown to reduce biases on average, even in the presence of non-stationarity. Quantile-mapping bias correction has been applied at spatial scales ranging from hundreds of kilometers to individual points, such as weather station locations. Since water resources and other models used to simulate climate impacts are sensitive to biases in input meteorology, there is a motivation to apply bias correction at a scale fine enough that the downscaled data closely resemble historically observed data, though past work has identified undesirable consequences to applying quantile mapping at too fine a scale. This study explores the role of the spatial scale at which the quantile-mapping bias correction is applied, in the context of estimating high and low daily streamflows across the western United States. We vary the spatial scale at which quantile-mapping bias correction is performed from 2° ( ˜ 200 km) to 1/8° ( ˜ 12 km) within a statistical downscaling procedure, and use the downscaled daily precipitation and temperature to drive a hydrology model. We find that little additional benefit is obtained, and some skill is degraded, when using quantile mapping at scales finer than approximately 0.5° ( ˜ 50 km). This can provide guidance to those applying the quantile-mapping bias correction method for hydrologic impacts analysis.

    Statistical downscaling is a commonly used technique for translating large-scale climate model output to a scale appropriate for assessing impacts. To ensure downscaled meteorology can be used in climate impact studies, downscaling must correct biases in the large-scale signal. A simple and generally effective method for accommodating systematic biases in large-scale model output is quantile mapping, which has been applied to many variables and shown to reduce biases on average, even in the presence of non-stationarity. Quantile mapping bias correction has been applied at spatial scales ranging from areas of hundreds of kilometers to individual points, such as weather station locations. Since water resources and other models used to simulate climate impacts are sensitive to biases in input meteorology, there is a motivation to apply bias correction at a scale fine enough that the downscaled data closely resembles historically observed data, though past work has identified undesirable consequences to applying quantile mapping at too fine a scale. This study explores the role of the spatial scale at which the quantile-mapping bias correction is applied, in the context of estimating high and low daily streamflows across the Western United States. We vary the spatial scale at which quantile mapping bias correction is performed from 2° (∼ 200 km) to 1/8° (∼ 12 km) within a statistical downscaling procedure, and use the downscaled daily precipitation and temperature to drive a hydrology model. We find that little additional benefit is obtained, and some skill is degraded, when using quantile mapping at scales finer than approximately 0.5° (∼ 50 km). This can provide guidance to those applying the quantile mapping bias correction method for hydrologic impacts analysis.

    This study investigates the role of context-specific authenticity at work for work-related outcomes (intrinsic motivation, work ability) and depressivity. Furthermore reciprocal relations between work-related authenticity and healthy psychological functioning are investigated. Longitudinal data from 1,243 employees from 63 subsidiaries of a non-profit organization in the social sector were analyzed using multilevel structural equation modeling. Work-related authenticity at T1 predicted work ability and depressivity, but not intrinsic motivation at T2, about 6 months later. Work-related authenticity at T2 was predicted by intrinsic motivation and depressivity, but not by work ability at T1. We conclude that work-related authenticity and healthy psychological functioning are positively reinforcing each other. Thus, enabling employees to be authentic supposedly increases their well-being and is a pivotal opportunity for organizations to foster health and performance-related indicators like work ability and prevent negative health indicators like depressivity. At the same time, authenticity of employees can be fostered through workplace health promotion.

    Workforce recruitment and retention are issues in radiation oncology. The working environment is likely to have an impact on retention; however, there is a lack of research in this area. The objectives of this study were to: investigate radiation therapists' (RTs) and radiation oncology medical physicists' (ROMPs) perceptions of work and the working environment; and determine the factors that influence the ability of RTs and ROMPs to undertake their work and how these factors affect recruitment and retention. Semi-structured interviews were conducted and thematic analysis was used. Twenty-eight RTs and 21 ROMPs participated. The overarching themes were delivering care, support in work, working conditions and lifestyle. The overarching themes were mostly consistent across both groups; however, the exemplars reflected the different roles and perspectives of RTs and ROMPs. Participants described the importance they placed on treating patients and improving their lives. Working conditions were sometimes difficult with participants reporting pressure at work, large workloads and longer hours and overtime. Insufficient staff numbers impacted on the effectiveness of staff, the working environment and intentions to stay. Staff satisfaction is likely to be improved if changes are made to the working environment. We make recommendations that may assist departments to support RTs and ROMPs.

    Verbal working memory (VWM) engages frontal and temporal/parietal circuits subserving the phonological loop, as well as, superior and inferior cerebellar regions which have projections from these neocortical areas. Different cerebro-cerebellar circuits may be engaged for integrating aurally- and visually-presented information for VWM. The present fMRI study investigated load (2, 4, or 6 letters) and modality (auditory and visual) dependent cerebro-cerebellar VWM activation using a Sternberg task. FMRI revealed modality-independent activations in left frontal (BA 6/9/44), insular, cingulate (BA 32), and bilateral inferior parietal/supramarginal (BA 40) regions, as well as in bilateral superior (HVI) and right inferior (HVIII) cerebellar regions. Visual presentation evoked prominent activations in right superior (HVI/CrusI) cerebellum, bilateral occipital (BA19) and left parietal (BA7/40) cortex while auditory presentation showed robust activations predominantly in bilateral temporal regions (BA21/22). In the cerebellum, we noted a visual to auditory emphasis of function progressing from superior to inferior and from lateral to medial regions. These results extend our previous findings of fMRI activation in cerebro-cerebellar networks during VWM, and demonstrate both modality dependent commonalities and differences in activations with increasing memory load.

    Between 1955 and 1973, an estimated 750,000 kg of carbon tetrachloride were discharged to the soil in the 200 West Area of the Hanford Site as part of the plutonium production process. Of this amount, some carbon tetrachloride reached the groundwater more than 70 m below the ground surface and formed a plume of 10 km2. Recent information has shown that the carbon tetrachloride plume extends to a depth of at least 60 m below the water table. Some carbon tetrachloride has been degraded either by the original process or subsequent transformations in the subsurface to form a co-existing chloroform plume. Although current characterization efforts are improving the conceptual model of the source area, more information is needed to effectively assess the fate and transport of carbon tetrachloride and chloroform to support upcoming remediation decisions for the plume. As noted in a simulation study by Truex et al. (2001), parameters describing porosity, sorption, and abiotic degradation have the largest influence on predicted plume behavior. The work proposed herein will improve the ability to predict future plume movement by better quantifying abiotic degradation mechanisms and rates. This effort will help define how much active remediation may be needed and estimate where the plume will eventually stabilize – key factors in determining the most appropriate remedy for the plume.

    Isocyanates, known to cause respiratory sensitization and asthma, are widely used in automotive refinishing where exposures to aliphatic polyisocyanates occur by both inhalation and skin contact. The work reported here, the characterization of isocyanate exposure in the autobody industry, was part of an epidemiologic study of workers in 37 autobody shops in Connecticut. This article describes workplaces, tasks, and controls, and outlines the frequency, duration, and intensity of isocyanate exposures. Personal air samples taken outside of respirators had median concentrations of 66.5 microg NCO/m3 for primer, 134.4 microg (NCO)/m3 for sealer, and 358.5 microg NCO/m3 for clearcoat. Forty-eight percent of primer, 66% of sealer, and 92% of clearcoat samples exceeded the United Kingdom Health and Safety Executive guideline for isocyanate, though none exceeded the National Institute for Occupational Safety and Health (NIOSH) recommended exposure limit for monomer. Nonisocyanate-containing primers and sealers are used in more than half the shops, but nonisocyanate clearcoats are rare. Eighty-two percent of personal samples taken within a spray booth exceeded the U.K. guideline: 81% of those in downdraft spray booths, 74% in semidowndraft booths, and 92% in crossdraft booths. Only 8% of shops reported that spraying is done exclusively in spray booths. All painters wore some type of respirator. In 30% of shops, painters used supplied air respirators; the rest relied on half face organic vapor cartridge respirators with N95 overspray pads. All shops provided some type of gloves, usually latex, not recommended for isocyanate protection. Despite improvements in autobody shop materials, practices, and controls, there are still opportunities for substantial exposures to isocyanates.

It concerns 'doing quantum mechanics using only pictures of lines, squares, triangles and diamonds'. This picture calculus can be seen as a very substantial extension of Dirac's notation, and has a purely algebraic counterpart in terms of so-called Strongly Compact Closed Categories (introduced by Abramsky and I which subsumes my Logic of Entanglement.

    Study Objectives: Work-family conflict is a threat to healthy sleep behaviors among employees. This study aimed to examine how Work-to-Family Conflict (demands from work that interfere with one's family/personal life; WTFC) and Family-to-Work Conflict (demands from family/personal life that interfere with work; FTWC) are associated with several dimensions of sleep among information technology workers. Methods: Employees at a U.S. IT firm (n = 799) provided self-reports of sleep sufficiency (feeling rested upon waking), sleep quality, and sleep maintenance insomnia symptoms (waking up in the middle of the night or early morning) in the last month. They also provided a week of actigraphy for nighttime sleep duration, napping, sleep timing, and a novel sleep inconsistency measure. Analyses adjusted for work conditions (job demands, decision authority, schedule control, and family-supportive supervisor behavior), and household and sociodemographic characteristics. Results: Employees who experienced higher WTFC reported less sleep sufficiency, poorer sleep quality, and more insomnia symptoms. Higher WTFC also predicted shorter nighttime sleep duration, greater likelihood of napping, and longer nap duration. Furthermore, higher WTFC was linked to greater inconsistency of nighttime sleep duration and sleep clock times, whereas higher FTWC was associated with more rigidity of sleep timing mostly driven by wake time. Conclusions: Results highlight the unique associations of WTFC/FTWC with employee sleep independent of other work conditions and household and sociodemographic characteristics. Our novel methodological approach demonstrates differential associations of WTFC and FTWC with inconsistency of sleep timing. Given the strong associations between WTFC and poor sleep, future research should focus on reducing WTFC. Citation: Buxton OM, Lee S, Beverly C, Berkman LF, Moen P, Kelly EL, Hammer LB, Almeida DM.

    The primary objective of the work scope described in this technical work plan (TWP) is to enhance the descriptions of fracture and lithophysal parameters for the repository host horizon (RHH) over the repository footprint utilizing a predictive model. This work is planned to address U.S. Nuclear Regulatory Commission (NRC) additional information needs (AINs) associated with the Structural Deformation and Seismicity (SDS) Key Technical Issues (KTI) agreement SDS 3.03 (Schlueter 2000 [DIRS 166615]). The results of the planned work are expected to enhance the technical basis and confirm the results of the fracture analyses presented in ''Drift Degradation Analysis'' (BSC 2004 [DIRS 166107], Section 6.1.6). This model is not intended to provide an alternative for the unsaturated zone and saturated zone flow and transport models currently used by the Yucca Mountain Project (YMP). Nor are the outputs of this model intended to address the SDS 3.03 AINs related to the unsaturated zone and saturated zone flow and transport models.

  2. Work time control, sleep & accident risk: A prospective cohort study.

    Tucker, Philip; Albrecht, Sophie; Kecklund, Göran; Beckers, Debby G J; Leineweber, Constanze

    We examined whether the beneficial impact of work time control (WTC) on sleep leads to lower accident risk, using data from a nationally representative survey conducted in Sweden. Logistic regressions examined WTC in 2010 and 2012 as predictors of accidents occurring in the subsequent 2 years (N = 4840 and 4337, respectively). Sleep disturbance and frequency of short sleeps in 2012 were examined as potential mediators of the associations between WTC in 2010 and subsequent accidents as reported in 2014 (N = 3636). All analyses adjusted for age, sex, education, occupational category, weekly work hours, shift work status, job control and perceived accident risk at work. In both waves, overall WTC was inversely associated with accidents (p = 0.048 and p = 0.038, respectively). Analyses of the sub-dimensions of WTC indicated that Control over Daily Hours (influence over start and finish times, and over length of shift) did not predict accidents in either wave, while Control over Time-off (CoT; influence over taking breaks, running private errands during work and taking paid leave) predicted fewer accidents in both waves (p = 0.013 and p = 0.010). Sleep disturbance in 2012 mediated associations between WTC/CoT in 2010 and accidents in 2014, although effects' sizes were small (effectWTC = -0.006, 95% confidence interval [CI] = -0.018 to -0.001; effectCoT = -0.009, 95%CI = -0.022 to -0.001; unstandardized coefficients), with the indirect effects of sleep disturbance accounting for less than 5% of the total direct and indirect effects. Frequency of short sleeps was not a significant mediator. WTC reduces the risk of subsequently being involved in an accident, although sleep may not be a strong component of the mechanism underlying this association.

    The purpose of this case study was to describe how the return-to-work process evolved in an employee with cancer in the Netherlands and how a work-directed intervention supported this process. The patient was a 35-year old female employee diagnosed with cervix carcinoma. After surgery, the patient experienced depression, fatigue, fear of recurrence, and low mental working capacity. Communication with the occupational physician was difficult. A social worker at the hospital provided three counselling sessions aimed to support return to work and sent letters to the occupational physician to improve the communication. The support by the social worker helped the patient to resume work gradually and the sending of information from the treating physician and social worker improved the communication with the occupational physician. This resulted in the patient being able to achieve lasting return to work. This work-directed intervention was highly valued by the patient and could be an important addition to usual psycho-oncological care for employees with cancer.

    When niching or speciation is required to perform a task that has several different component parts, standard genetic algorithms (GAs) struggle. They tend to evaluate and select all individuals on the same part of the task, which leads to genetic convergence within the population. The goal of evolutionary niching methods is to enforce diversity in the population so that this genetic convergence is avoided. One drawback with some of these niching methods is that they require a priori knowledge or assumptions about the specific fitness landscape in order to work; another is that many such methods are not set up to work on cooperative tasks where fitness is only relevant at the group level. Here we address these problems by presenting the group GA, described earlier by the authors, which is a group-based evolutionary algorithm that can lead to emergent niching. After demonstrating the group GA on an immune system matching task, we extend the previous work and present two modified versions where the number of niches does not need to be specified ahead of time. In the random-group-size GA, the number of niches is varied randomly during evolution, and in the evolved-group-size GA the number of niches is optimized by evolution. This provides a framework in which we can evolve groups of individuals to collectively perform tasks with minimal a priori knowledge of how many subtasks there are or how they should be shared out.

    NASA Technical Reports Server (NTRS)

    1984-01-01

    The work breakdown structure (WBS) for the Space Platform Expendables Resupply Concept Definition Study is described. The WBS consists of a list of WBS elements, a dictionary of element definitions, and an element logic diagram. The list and logic diagram identify the interrelationships of the elements. The dictionary defines the types of work that may be represented by or be classified under each specific element. The Space Platform Expendable Resupply WBS was selected mainly to support the program planning, scheduling, and costing performed in the programmatics task (task 3). The WBS is neither a statement-of-work nor a work authorization document. Rather, it is a framework around which to define requirements, plan effort, assign responsibilities, allocate and control resources, and report progress, expenditures, technical performance, and schedule performance. The WBS element definitions are independent of make-or-buy decisions, organizational structure, and activity locations unless exceptions are specifically stated.

    The study aimed to determine the risk factors for incident carpal tunnel syndrome (CTS) in a large working population, with a special focus on factors related to work organization. In 2002-2005, 3710 workers were assessed and, in 2007-2010, 1611 were re-examined. At baseline all completed a self-administered questionnaire about personal/medical factors and work exposure. CTS symptoms and physical examination signs were assessed by a standardized medical examination at baseline and follow-up. The risk of "symptomatic CTS" was higher for women (OR = 2.9 [1.7-5.2]) and increased linearly with age (OR = 1.04 [1.00-1.07] for 1-year increment). Two work organizational factors remained in the multivariate risk model after adjustment for the personal/medical and biomechanical factors: payment on a piecework basis (OR = 2.0, 95% CI 1.1-3.5) and work pace dependent on automatic rate (OR = 1.9, 95% CI 0.9-4.1). Several factors related to work organization were associated with incident CTS after adjustment for potential confounders.

    2016-06-01

    Purpose To longitudinally investigate (1) whether lower work ability and work engagement predict the use of company policies on reduced working hours and exemption from evening/night work among older workers, and (2) whether using such policies subsequently contribute to higher work ability and work engagement. Methods In total 6922 employees (45-64 years) participating in the first three waves of the Study on Transitions in Employment, Ability and Motivation were included. Participants yearly filled out an online questionnaires. Regression analyses were applied to study the influence of baseline work ability and work engagement on the incident use of policies during the first year of follow-up, and the incident use of these policies on work ability and work engagement during the second year of follow-up. Results Employees with a higher work ability were less likely to start using the policy 'reduced working hours' [OR 0.91 (95 % CI 0.83-0.98)]. Starting to use this policy was in turn related to lower work ability 1 year later [B -0.28 (95 % CI -0.47 to -0.08)]. Starting to use the policy 'exemption from evening/night work' was related to higher work engagement 1 year later [B 0.23 (95 % CI 0.07-0.39)]. Conclusions Low work ability precedes the use of some company policies aiming to support sustainable employability of older workers. Further research is needed to explore whether company policies result in a (longstanding) improvement, or reduced deterioration, of older workers' employability.

    Body height decreases throughout the day due to fluid loss from the intervertebral disk. This study investigated whether spinal shrinkage was greater during workdays compared with nonwork days, whether daily work stressors were positively related to spinal shrinkage, and whether job control was negatively related to spinal shrinkage. In a consecutive 2-week ambulatory field study, including 39 office employees and 512 days of observation, spinal shrinkage was measured by a stadiometer, and calculated as body height in the morning minus body height in the evening. Physical activity was monitored throughout the 14 days by accelerometry. Daily work stressors, daily job control, biomechanical workload, and recreational activities after work were measured with daily surveys. Multilevel regression analyses showed that spinal disks shrank more during workdays than during nonwork days. After adjustment for sex, age, body weight, smoking status, biomechanical work strain, and time spent on physical and low-effort activities during the day, lower levels of daily job control significantly predicted increased spinal shrinkage. Findings add to knowledge on how work redesign that increases job control may possibly contribute to preserving intervertebral disk function and preventing occupational back pain.

    2016-02-03

    These notes provide a pedagogical discussion of the physics of piezoelectricity. The exposition starts with a brief analysis of the classical (continuum) theory of piezoelectric phenomena in solids. The main subject of the notes is, however, a quantum mechanical analysis. We first derive the Frohlich Hamiltonian as part of the description of the electron-phonon interaction. The results of this analysis are then employed to derive the equations of piezoelectricity. A couple of examples with the zinc blende and and wurtzite structures are presented at the end

  18. The Composer’s Program Note for Newly Written Classical Music: Content and Intentions

    2016-01-01

    In concerts of western classical music the provision of a program note is a widespread practice dating back to the 18th century and still commonly in use. Program notes tend to inform listeners and performers about historical context, composer biographical details, and compositional thinking. However, the scant program note research conducted to date reveals that program notes may not foster understanding or enhance listener enjoyment as previously assumed. In the case of canonic works, performers and listeners may already be familiar with much of the program note information. This is not so in the case of newly composed works, which formed the basis of the exploratory study reported here. This article reports the views of 17 living contemporary composers on their writing of program notes for their own works. In particular, the study sought to understand the intended recipient, role and the content of composer-written program notes. Participating composers identified three main roles for their program notes: to shape a performer’s interpretation of the work; to guide, engage or direct the listener and/or performer; and as collaborative mode of communication between the composer, performer, and listener. For some composers, this collaboration was intended to result in “performative listening” in which listeners were actively engaged in bringing each composition to life. This was also described as a form of empathy that results in the co-construction of the musical experience. Overall, composers avoided giving too much personal information and they provided performers with more structural information. However, composers did not agree on whether the same information should be provided to both performers and listeners. Composers’ responses problematize the view of a program note as a simple statement from writer to recipient, indicating instead a more complex set of relations at play between composer, performer, listener, and the work itself. These relations

    Aim There is evidence that childhood trauma is a risk factor for the development of psychosis and it is recommended that childhood trauma is inquired about in all patients presenting with psychosis. This study aimed to determine the prevalence of childhood trauma in patients in the UK Early Intervention Service based on a case note review. Methods This is a retrospective case note study of 296 patients in an UK Early Intervention Service. Trauma history obtained on service entry was reviewed and trauma experienced categorized. Results were analyzed using crosstab and frequency analysis. Results The mean age of the sample was 24 years, 70% were male, 66% were White, and 23% Asian (ethnicity not documented in 11% of the sample). Approximately 60% of patients reported childhood trauma, 21% reported no childhood trauma, and data were not recorded for the remaining 19%. Among those reporting trauma, the prevalence of most frequently reported traumas were: severe or repeated disruption (21%), parental mental illness (19%), bullying (18%), absence of a parent (13%), and ‘other’ trauma (24%) – the majority of which were victimization events. Sixty-six percent of those reporting trauma had experienced multiple forms of trauma. Conclusion A high prevalence of childhood trauma (particularly trauma related to the home environment or family unit) was reported. This is consistent with other studies reporting on trauma and psychosis. The main weakness of the study is a lack of a control group reporting experience of childhood trauma in those without psychosis. Guidelines recommend that all patients with psychosis are asked about childhood trauma; but in 19% of our sample there was no documentation that this had been done indicating the need for improvement in assessment.

    This study examined the health status of injured workers with musculoskeletal disorders enrolled in the Malaysian Return to Work (RTW) program. The 102 participants were categorized into three RTW groups: Off-work (n = 30, 29.4%), Re-entry (n = 44, 43.1%), and Maintenance (n = 28, 27.5%). Overall health status, as measured by the SF-36 version 2, of the workers exhibited below average compared to the internationally established normative population, with their physical health component summary rated lower than mental health. Across the different groups, significant differences were found in role-physical, vitality, bodily pain, general health, and mental health. However, the mean values of these variables were higher in the Maintenance group and were found significant. The current health status of injured workers at Off-work and Re-entry phases was significantly low and warranted to be improved by involving other health professionals such as occupational therapists, ergonomists, and psychologists.

  13. Baseline study of effects of ionizing radiation on the chromosomes of the marine worm, 'Neanthes arenaceodentata'. Technical note

    1981-09-01

    Between 1946 and 1970 the United States disposed of low level radioactive waste at several sites in the Atlantic and Pacific Ocean. In 1972 the Environmental Protection Agency was authorized under the Marine Protection Research and Sanctuaries Act (PL-92-532) to regulate all ocean disposal activities. This Act requires EPA to establish a program for reviewing and evaluating ocean dumping permit applications. Before EPA can approve permits for ocean dumping of radioactive waste, it will be necessary to determine how such wastes may affect marine biota. The purpose of this study was to test the feasibility of using a marine coastal worm, Neanthes arenaceodentata, as a cytogenetic model for assessing radiation damage to ocean organisms. Groups of worms were exposed to cobalt-60, then slide preparations were made and scored for gross chromosome aberrations and damage. All the levels of ionizing radiation tested from 180-680 rads were found to cause significant chromosome damage in N. arenaceodentata. The nature of this damage depended on dose, dose-rate and DNA repair capability of the worm. Worms responded to the same dose range as do mice. Since mice are accepted models for studying radiation effects on humans, this study supports the utility of using this species to study radiation effects on marine organisms.

  15. Effect of skill level on recall of visually presented patterns of musical notes.

    PubMed

    Kalakoski, Virpi

    2007-04-01

    Expertise effects in music were studied in a new task: the construction of mental representations from separate fragments. Groups of expert musicians and non-musicians were asked to recall note patterns presented visually note by note. Skill-level, musical well-formedness of the note patterns and presentation mode were varied. The musicians recalled note patterns better than the non-musicians, even though the presentation was visual and successive. Furthermore, only musicians' performance was affected by musical well-formedness of the note patterns when visual gestalt properties, verbal rehearsability, and familiarity of the stimuli were controlled. Musicians were also able to use letter names referring to notes as efficiently as visual notes, which indicates that the better recall of musicians cannot be explained by perceptual visual chunking. These results and the effect of skill level on the distribution of recall errors indicate that the ability to chunk incoming information into meaningful units does not require that complete familiar patterns are accessible to encoding processes, yet previous knowledge stored in long-term memory affects representation construction in working memory. The present method offers a new reliable tool, and its implications to the research on construction of representations and musical imagery are discussed.

    This study effort has shown that the development of a space robotic servicing system is totally feasible. More importantly, many of the key elements of such a system are currently available as the result of previous and ongoing technical efforts. In many cases, decisions remain to be made concerning tradeoffs between options available to satisfy system technology requirements. The primary recommendation resulting from this study is for the development of a flight test bed system that could be used to establish a performance database to assist some of the necessary technical decisions described in the study package. A properly design flight test bed system would prove tremendously useful in terms of rapidly evaluating technology in a realistic setting and would be a great benefit in the development of the operational system.

    The present study examined the roles of work factors (i.e. job demands and job resources), work-family conflicts and culture on predictors of healthy intentions (fruit and vegetable consumption, low-fat diet and physical activity) within the framework of the theory of planned behaviour (TPB). Employees from the United Kingdom (N = 278) and Malaysia (N = 325) participated in the study. Results indicated that higher job demands were significantly related to lower intentions to eat a low-fat diet. Women reported higher intentions to eat a low-fat diet than men did, while participants from the United Kingdom had lower intentions to engage in physical activity compared with those from Malaysia. The efficacy of TPB variables in explaining intentions was verified, with perceived behavioural control (i.e. self-efficacy), attitudes and descriptive norms combined with past behaviour predictive across the samples. The results also suggest the roles of culture and work interference with family variables in moderating TPB-intention relationships and confirm that TPB variables mediate the effects of job demands and job resources on intentions. Practically, to promote health, identifying strategies to reduce stress factors; specifying important cognitive factors affecting work factors and thus, healthy intentions; and acknowledging cultural-specific determinants of healthy intentions are recommended.

    Dental microwear has been used for decades to reconstruct the diets of fossil hominins and bioarchaeological populations. The basic theory has been that hard-brittle foods (e.g., nuts, bone) require crushing and leave pits as they are pressed between opposing cheek-tooth surfaces, whereas soft-tough foods (e.g., grass blades, meat) require shearing and leave scratches as they are dragged along opposing surfaces that slide past one another. However, recent studies have called into question the efficacy of microwear as an indicator of diet. One issue has been the limited number of in vitro studies providing empirical evidence for associations between microwear pattern and chewing behavior. We here describe a new study using a chewing simulator, the BITE Master II, to examine the effects of angle of approach between opposing teeth and food consistency on microwear surface texture. Results indicate that opposing teeth that approach one another: 1) perpendicular to the occlusal plane (crushing) result in pits; 2) parallel to the occlusal plane (shearing) result in striations in the direction of movement; and 3) oblique to the occlusal plane (45°) result in both striations and pits. Results further suggest that different food types and abrasive loads affect the propensity to accumulate microwear features independent of feature shapes.

    The aim of present study was to enhance the dissolution rate of poorly water-soluble drug aceclofenac by solid dispersion technique using corn starch, dicalcium phosphate, lactose, and microcrystalline cellulose as carriers. Solid dispersions were prepared by solvent wetting method using 3(2) full factorial design for each of the carrier. The prepared solid dispersions were evaluated for differential scanning calorimetry, X-ray diffraction, scanning electron microscopy, Fourier-transform infrared spectroscopy (FTIR), and angle of repose. In vitro dissolution studies were carried out in phosphate buffer (pH 7.5) and 0.1 N HCl (pH 1.2). The results of solid state characterization bring to view that in solid dispersions the crystalline drug gets converted to its amorphous form. FTIR study results indicated the absence of interaction between aceclofenac and carriers. For prepared solid dispersions, angle of repose was found to be in the range of 26.19° to 35.29°, which indicates good flowability. Enhanced drug dissolution was obtained with carrier in order lactose > corn starch > microcrystalline cellulose > dicalcium phosphate. Hence, these carriers could be used to enhance the dissolution rate of poorly water-soluble drug.

    Posture, gait and balance problems are very disabling symptoms in Parkinson's disease (PD). An increased stride-to-stri de variability, reduction of automaticity and asymmetry of lower limbs function characterize parkinsonian gait. These features predispose to freezing of gait (FOG), which often leads to falls. The aim of this study was to evaluate how the modulation of asymmetry through physiotherapy might improve gait and reduce FOG, thus preventing falls. Twenty-eight PD patients entered a double-blind pilot feasibility controlled study and were evaluated at baseline and after 3 months of a rehabilitative program (performed twice a week) by means of the motor part of the Unified Parkinson's Disease Rating Scale (UPDRS-III), Gait and Falls Questionnaire, Tinetti balance and gait scale, Short Physical Performance Battery (SPPB), European Quality of Life questionnaire. Patients were randomly assigned to three treatment arms: (1) worst side improvement; (2) best side improvement; (3) standard therapy. All study arms showed a significant improvement of the Tinetti and SPPB scores. BSI led to a greater improvement than ST in terms of UPDRS-III (p = 0.01); Tinetti total score (p = 0.05) and Tinetti gait subscore (p = 0.01). Our study confirms the efficacy of physical therapy in the treatment of PD and, more importantly, suggests that specific intervention tailored on individual feature (e.g., asymmetry of motor condition) might be even more effective than standard rehabilitative programs.

    Beth Israel Medical Center (BIMC), in collaboration with the Centers for Disease Control (CDC) and the New York State Department of Health (NYSDOH), used respondent-driven sampling (RDS) in a study of HIV seroprevalence among drug users in New York City in 2004. We report here on operational issues with RDS including recruitment, coupon distribution, storefront operations, police and community relations, and the overall lessons we learned. Project staff recruited eight seeds from a syringe exchange in Lower Manhattan to serve as the initial study participants. Upon completion of the interview that lasted approximately 1 h and a blood draw, each seed was given three coupons to recruit three drug users into the study. Each of the subsequent eligible participants was also given three coupons to recruit three of their drug-using acquaintances. Eligible participants had to have: injected, smoked or snorted an illicit drug in the last 6 months (other than marijuana), aged 18 or older, adequate English language knowledge to permit informed consent and complete questionnaire. From April to July 2004, 618 drug users were interviewed, including 263 (43%) current injectors, 119 (19%) former injectors, and 236 (38%) never injectors. Four hundred sixty nine (76%) participants were men, 147 (24%) were women, and two (<1%) were transgender. By race/ethnicity, 285 (46%) were black, 218 (35%) Hispanic, 88 (14%) white, 23 (4%) mixed/not specified, and four (<1%) native American. Interviews were initially done on a drop-in basis but this system changed to appointments 1 month into the study due to the large volume of subjects coming in for interviews. Data collection was originally proposed to last for 1 year with a target recruitment of 500 drug users. Utilizing RDS, we were able to recruit and interview 118 more drug users than originally proposed in one quarter of the time. RDS was efficient with respect to time and economics (we did not have to hire an outreach worker) and

    We construct a micro-perfusion system using piston screw pump generators for use during real-time, high-pressure physiological studies. Perfusion is achieved using two generators, with one generator being compressed while the other is retracted, thus maintaining pressurization while producing fluid flow. We demonstrate control over perfusion rates in the 10-μl/s range and the ability to change between fluid reservoirs at up to 50 MPa. We validate the screw-pump approach by monitoring the cyanide-induced response of UV-excited autofluorescence from Saccharomyces cerevisiae under pressurization.

For quantitative measure of deciding which modes have to be moved and by how much, we introduce a new index called the matching index (I{sub M}), as a measure of how close a HOM is to the nearest beam mode. Depending on the value of I{sub M}, the operating scenarios are classified as safe and unsafe.

    2015-06-01

    This study explored the relationship between anxiety and scuba diving performance of young individuals (N = 44; 16.9 yr., SD = 1.2) participating in an introductory scuba diving activity. The question was whether the well-known negative correlation between anxiety and scuba diving performance found for experienced and middle-aged scuba divers will be observed in young participants in their first dive experience. Diving instructors rated standardized scuba diving skills that were correlated with individual state and trait anxiety. There was no relationship between anxiety and scuba diving performance, neither for state nor for trait anxiety. This non-significant correlation between anxiety and performance was in contrast to recent findings observed for experienced divers or those who participated at a scuba diving training program. Considering the differences in methodological design between this study and recent investigations, further research is needed to reveal possible relations between anxiety, scuba diving performance, and panic behavior in beginner-level youth or adults.

    Purpose Femoral intertrochanteric fractures are common in the elderly. Appropriate surgical fixation of trochanteric fracture fragments can restore normal anatomical structure and ambulation, and can aid in the recovery of biomechanical function of the hip. We evaluated clinical outcomes of bipolar hemiarthroplasty using a wiring technique for trochanteric fracture fragment fixation. Materials and Methods From September 2006 to February 2015, a total of 260 cases underwent simultaneous bipolar hemiarthroplasty and wire fixation. A total of 65 patients (69 hips) with an average age of 78 years and more than one year of follow-up was included in the study. Using pre-, postoperative and follow-up radiograms, we evaluated wire fixation failure and also assessed changes in walking ability. Results Loosening or osteolysis around the stem was not observed; however, we did observe bone growth around the stem (54 cases), cortical hypertrophy (6 cases), a wide range of sclerotic lines but no stem subsidence (1 case), wire breakage (9 cases), and fracture fragment migration with no significant functional deficiency (2 cases). Conclusion Our study showed that additional wiring for trochanteric fracture fragment fixation following bipolar hemiarthroplasty can help restore normal anatomy. The added stability results in faster rehabilitation, and good clinical and radiographic outcomes. We recommend this procedure in this type of fracture. PMID:28316962

    2001-07-01

    The CSM3 137Cs type stainless-steel encapsulated source is widely used in manually afterloaded low dose rate brachytherapy. A specially asymmetric source, CSM3-a, has been designed by CIS Bio International (France) substituting the eyelet side seed with an inactive material in the CSM3 source. This modification has been done in order to allow a uniform dose level over the upper vaginal surface when this `linear' source is inserted at the top of the dome vaginal applicators. In this study the Monte Carlo GEANT3 simulation code, incorporating the source geometry in detail, was used to investigate the dosimetric characteristics of this special CSM3-a 137Cs brachytherapy source. The absolute dose rate distribution in water around this source was calculated and is presented in the form of an along-away table. Comparison of Sievert integral type calculations with Monte Carlo results are discussed.

    2016-04-01

    Accurate prediction of groundwater table is important for the efficient management of groundwater resources. Despite being the most widely used tools for depicting the hydrological regime, numerical models suffer from formidable constraints, such as extensive data demanding, high computational cost, and inevitable parameter uncertainty. Artificial neural networks (ANNs), in contrast, can make predictions on the basis of more easily accessible variables, rather than requiring explicit characterization of the physical systems and prior knowledge of the physical parameters. This study applies ANN to predict the groundwater table in a freshwater swamp forest of Singapore. The inputs to the network are solely the surrounding reservoir levels and rainfall. The results reveal that ANN is able to produce an accurate forecast with a leading time of 1 day, whereas the performance decreases when leading time increases to 3 and 7 days.

    Alviso, C; Harvey, C; Vance, A

    2005-11-23

    Compatibility and outgassing studies of non-nuclear materials were carried out in support of the W80 Life Extension Program. These studies included small-scale laboratory experiments as well as participation in Sandia's Materials Aging and Compatibility test (MAC-1). Analysis of the outgassing signature of removable epoxy foam (REF) revealed unusually high levels of volatile organic compounds in the material. REF was replaced with the polyurethane PMDI. Laboratory compatibility tests of high priority materials were performed and revealed incompatibilities between Viton A (LX-07 binder) and syntactic polysulfide as well as Viton A and REF. With the removal of REF from the system, the incompatibility with Viton A is not an issue. In the case of the viton/polysulfide, both of these materials have a history of reliability in the stockpile, and the observed results, while scientifically interesting, appear to be a laboratory anomaly. Participation in the MAC-1 test led to a detailed study of Viton A degradation. At elevated temperatures up to 70 C, the Viton A samples darkened and exhibited increased crosslinking. Laboratory experiments were pursued to correlate the observed changes to exposure to specific compounds that were present in the MAC-1 canister atmospheres. Exposure to siloxanes resulted in changes similar to those seen in the MAC-1 samples. Knowledge gained from the MAC-1 test will be applied to the upcoming MAC-2 test planned for FY06. Finally, the suitability of isotopically labeled nitrogen fill gas ({sup 15}N{sub 2}) was addressed. This gas will behave as standard nitrogen with no compatibility concerns expected.

  15. What really works? An exploratory study of condom negotiation strategies.

    PubMed

    Lam, Amy G; Mak, Amy; Lindsay, Patricia D; Russell, Stephen T

    2004-04-01

    Verbal-direct strategies are assumed to be the most effective strategies in negotiating condom use. Both cultural and gender differences in communication styles suggest that individuals may negotiate condoms in ways that are not exclusively verbal and direct. This study examined the use of other forms of condom negotiations by developing an exploratory scale that distinguished strategies on how verbal and direct they were (i.e., verbal-direct, verbal-indirect, nonverbal-direct, nonverbal-indirect). The study compared the use of negotiation strategies among Asian and White American students at a northern California university. Results indicated that although direct strategies (verbal and nonverbal) were more frequently used, condom users also employed indirect strategies (verbal and nonverbal) to negotiate condom use. Moreover, Asians used verbal-indirect strategies more than Whites. Women used nonverbal-indirect strategies more than men. HIV preventions seeking to be culturally sensitive to Asians and women may benefit from incorporating these strategies into their interventions.

    2017-01-01

    Objectives To determine how to enhance integration of minority students in health education, and thereby improve intercultural communication skills and cultural sensitivity in a sample of health teacher students in Norway. Methods After a group-work intervention and for a period of six months afterwards we followed an “action research” approach and observed 47 health teachers-in-training in their first year at the Oslo and Akershus University College during classroom interactions. Data were qualitative and comprised student self-reports and survey results along with observations from three teachers, the authors of the study. Data were analyzed using a constant comparative approach with opinion categorization and an open coding procedure, with separate analyses performed on observations from minority students, majority students, and teachers. Results Both ethnic majority and minority students experienced an increase in intercultural knowledge and problem-solving ability after the experience of an early intervention in their first academic year of tertiary education. Students reacted favorably to the intervention and noted in class assessments both the challenges and rewards of overcoming cultural barriers. Teacher observation notes confirmed that early intervention led to an increase in interaction and cross-cultural engagement between minority and majority students compared to previous years’ classes without the intervention. Conclusions Early classroom intervention to promote intercultural engagement can prevent clique formation along majority/minority lines. The method used here, tailored group assignments in ethnically diverse working groups at the very beginning of students’ tertiary academic career, can be an effective approach to cultivating attitudes and skills fostering intercultural awareness and sensitivity.

    The quality of thorax and pelvis transmission scans and therefore of attenuation correction in PET depends on patient thickness and transmission rod source strength. The purpose of the present study was to assess the feasibility of using count-based transmission scans, thereby guaranteeing more consistent image quality and more precise quantification than with fixed transmission scan duration. First, the relation between noise equivalent counts (NEC) of 10 min calibration transmission scans and rod source activity was determined over a period of 1.5 years. Second, the relation between transmission scan counts and uniform phantom diameter was studied numerically, determining the relative contribution of counts from lines of response passing through the phantom as compared with the total number of counts. Finally, the relation between patient weight and transmission scan duration was determined for 35 patients, who were scanned at the level of thorax or pelvis. After installation of new rod sources, the NEC of transmission scans first increased slightly (5%) with decreasing rod source activity and after 3 months decreased with a rate of 2 3% per month. The numerical simulation showed that the number of transmission scan counts from lines of response passing through the phantom increased with phantom diameter up to 7 cm. For phantoms larger than 7 cm, the number of these counts decreased at approximately the same rate as the total number of transmission scan counts. Patient data confirmed that the total number of transmission scan counts decreased with increasing patient weight with about 0.5% kg-1. It can be concluded that count-based transmission scans compensate for radioactive decay of the rod sources. With count-based transmission scans, rod sources can be used for up to 1.5 years at the cost of a 50% increased transmission scan duration. For phantoms with diameters of more than 7 cm and for patients scanned at the level of thorax or pelvis, use of count

    Nichols, J.D.; Hepp, G.R.; Pollock, K.H.; Hines, J.E.

    1987-01-01

    Recently, Gill (1985) discussed the interpretation of capture history data resulting from his own studies on the red-spotted newt, Notophthalmus viridescens , and work by Husting (1965) on spotted salamanders, Ambystoma maculatum. Gill (1985) noted that gaps in capture histories (years in which individuals were not captured, preceded and followed by years in which they were) could result from either of two very different possibilities: (1) failure of the animal to return to the fenced pond to breed (the alternative Husting (1965) favored), or (2) return of the animal to the breeding pond, but failure of the investigator to capture it and detect its presence. The authors agree entirely with Gill (1985) that capture history data such as his or those of Husting (1965) should be analyzed using models that recognize the possibility of 'census error,' and that it is important to try to distinguish between such 'error' and skipped breeding efforts. The purpose of this note is to point out the relationship between Gill's (1985:347) null model and certain capture-recapture models, and to use capture-recapture models and tests to analyze the original data of Husting (1965).

    2015-06-01

    Five Psilocybe species with unresolved systematic position (P. atrobrunnea, P. laetissima, P. medullosa, P. pelliculosa, and P. silvatica) were investigated using four molecular markers (EF1-α, ITS, LSU, and IGS). Phylogenetic analysis revealed that with the exception of P. laetissima, which is now rightfully classified in the genus Leratiomyces, all investigated species belong to Psilocybe sect. Psilocybe. For the first time, psychotropic compounds psilocin and psilocybin were detected in P. medullosa using gas chromatography-mass spectrometry. On the contrary, neither psilocin, nor psilocybin was detected in P. atrobrunnea and negative results were also obtained from mycelia grown in vitro on tryptamine/tryptophan-amended media. These results strongly suggest that biosynthesis of these alkaloids was lost in P. atrobrunnea. With the exception of minor differences detected in EF1-α marker, all sequences of American and European collections of P. atrobrunnea were identical. On the other hand, a thorough nomenclatural study revealed that the name P. atrobrunnea must be considered dubious; the oldest available candidate name, P. fuscofulva, was therefore adopted. The molecular data suggests that morphologically identical American P. silvatica and European P. medullosa likely represent distinct species; epitypes of both taxa were therefore designated.

  1. Technical Note: A simple method for vaterite precipitation for isotopic studies: implications for bulk and clumped isotope analysis

    NASA Astrophysics Data System (ADS)

    Kluge, T.; John, C. M.

    2015-06-01

    Calcium carbonate (CaCO3) plays an important role in the natural environment as a major constituent of the skeleton and supporting structure of marine life and has high economic importance as an additive in food, chemicals and medical products. Anhydrous CaCO3 occurs in the three different polymorphs calcite, aragonite and vaterite, whereof calcite is the most abundant and best characterized mineral. In contrast, little is known about the rare polymorph vaterite, in particular with regard to the oxygen isotope fractionation between H2O and the mineral. Synthetic precipitation of vaterite in the laboratory typically involves rapid processes and isotopic non-equilibrium, which excludes isotope studies focused on the characterization of vaterite under equilibrium conditions. Here, we used a new experimental approach that enables vaterite mineral formation from an isotopically equilibrated solution. The solution consists of a ~0.007 mol L-1 CaCO3 solution that is saturated with NaCl at room temperature (up to 6.4 mol L-1). Vaterite precipitated as single phase or major phase (≥94%) in experiments performed between 23 and 91 °C. Only at 80 °C was vaterite a minor phase with a relative abundance of 27%. The high mineral yield per experiment of up to 235 mg relative to the initially dissolved CaCO3 amount of on average 360 mg enables an investigation of the oxygen isotope fractionation between the mineral and water, and the determination of clumped isotope values in vaterite.

  2. Oblique Lateral Lumbar Interbody Fusion (OLLIF): Technical Notes and Early Results of a Single Surgeon Comparative Study

    PubMed Central

    Abbasi, Hamid

    2015-01-01

    Background context: Lower back pain is one of the most prevalent and expensive health conditions in the Western world. The standard treatment, interbody fusion, is an invasive procedure that requires the stripping of muscles and soft tissue, leading to surgical morbidity. Current minimally invasive (MI) spinal fusions are technically demanding and suffer from technical limitations. Purpose: Oblique lumbar lateral interbody fusion (OLLIF) is a new technique for fusion of the lumbar spine that overcomes these complications. Outcome measures include patient demographics, reported outcomes, and surgical outcomes. Study design/Setting: Kambin's Triangle can easily be located as a silent window with an electrophysiological probe. Discectomy is performed through a single access portal with a 10 mm diameter. After a discectomy, the disc space is packed with beta-tricalcium phosphate soaked in autologous bone marrow, aspirated, and the cage is inserted. Finally, a minimally invasive posterior fixation is performed. Methods: OLLIF’s major innovation is to approach the disc through Kambin’s Triangle, aided by bilateral fluoroscopy. Results: We present data from 69 consecutive OLLIF surgeries on 128 levels with a control group of 55 consecutive open transformational lumbar interbody fusions (TLIFs) on 125 levels. For a single level OLLIF, the mean surgery time is 69 minutes (min) and blood loss is 29 ml. Surgery time was approximately twice as fast as open TLIF (mean: 135 min) and blood loss is reduced by over 80% compared to TLIF (mean: 355 ml). Conclusions: OLLIF is a minimally invasive fusion that significantly reduces surgery times compared to open surgery. OLLIF overcomes the difficulties of traditional open fusions, making it a safe and technically less demanding surgery than open or minimally invasive TLIF.  PMID:26623206

  3. Staying at work with chronic nonspecific musculoskeletal pain: a qualitative study of workers' experiences

    PubMed Central

    2011-01-01

    Background Many people with chronic nonspecific musculoskeletal pain (CMP) have decreased work ability. The majority, however, stays at work despite their pain. Knowledge about workers who stay at work despite chronic pain is limited, narrowing our views on work participation. The aim of this study was to explore why people with CMP stay at work despite pain (motivators) and how they manage to maintain working (success factors). Methods A semi-structured interview was conducted among 21 subjects who stay at work despite CMP. Participants were included through purposeful sampling. Interviews were audio-recorded, transcribed verbatim, and imported into computer software Atlas.ti. Data was analyzed by means of thematic analysis. The interviews consisted of open questions such as: "Why are you working with pain?" or "How do you manage working while having pain?" Results A total of 16 motivators and 52 success factors emerged in the interviews. Motivators were categorized into four themes: work as value, work as therapy, work as income generator, and work as responsibility. Success factors were categorized into five themes: personal characteristics, adjustment latitude, coping with pain, use of healthcare services, and pain beliefs. Conclusions Personal characteristics, well-developed self-management skills, and motivation to work may be considered to be important success factors and prerequisites for staying at work, resulting in behaviors promoting staying at work such as: raising adjustment latitude, changing pain-coping strategies, organizing modifications and conditions at work, finding access to healthcare services, and asking for support. Motivators and success factors for staying at work may be used for interventions in rehabilitation and occupational medicine, to prevent absenteeism, or to promote a sustainable return to work. This qualitative study has evoked new hypotheses about staying at work; quantitative studies on staying at work are needed to obtain

    The aim of this study was to measure return to work and duration until return to work in patients undergoing total hip or knee arthroplasty (THA or TKA). This prospective study included patients under 65 years of age, undergoing THA or TKA, who provided information on their work status preoperatively (paid work yes/no and working hours) and 1 year thereafter (paid work yes/no, working hours and time until return to work). Seventy-one THA and 64 TKA patients had a paid job preoperatively. The employment rates 1 year postoperatively were 64/71 (90 %) after THA and 53/64 (83 %) after TKA. Of those who returned to work, 9/64 (14 %) of THA patients and 10/53 (19 %) of TKA patients worked less hours than preoperatively [mean decrease of 16 (SD 11.5) and 14 (SD 13.0) hours, respectively]. The mean time to return to work was 12.5 (SD 7.6) and 12.9 (SD 8.0) weeks in THA and TKA, respectively. The majority of working patients who underwent THA or TKA returned to work, after approximately 12 weeks. A considerable proportion of the patients returning to work worked less hours than preoperatively. More research into patients who do not return or decrease their working hours is needed.

    Between 1952 and 1992, more than 200 large radiobiology studies were conducted in research institutes throughout Europe, North America, and Japan to determine the effects of external irradiation and internal emitters on the lifespan and tissue toxicity development in animals. At Argonne National Laboratory, 22 external beam studies were conducted on nearly 700 beagle dogs and 50,000 mice between 1969 and 1992. These studies helped to characterize the effects of neutron and gamma irradiation on lifespan, tumorigenesis, and mutagenesis across a range of doses and dosing patterns. The records and tissues collected at Argonne during that time period have been carefully preserved and redisseminated. Using these archived data, ongoing statistical work has been done and continues to characterize quality of radiation, dose, dose rate, tissue, and gender-specific differences in the radiation responses of exposed animals. The ongoing application of newly-developed molecular biology techniques to the archived tissues has revealed gene-specific mutation rates following exposure to ionizing irradiation. The original and ongoing work with this tissue archive is presented here as a case study of a more general trend in the radiobiology megastudies. These experiments helped form the modern understanding of radiation responses in animals and continue to inform development of new radiation models. Recent archival efforts have facilitated open access to the data and materials produced by these studies, and so a unique opportunity exists to expand this continued research.

    The objective of this study was to examine the associations of working conditions with major weight gain. Three different groups of work-related factors were examined: (i) work arrangements, (ii) physical working conditions, and (iii) psychosocial working conditions. The data are based on the Helsinki Health Study (HHS) questionnaire surveys. A baseline mail survey was made among middle-aged employees of the City of Helsinki in 2000-2002. A follow-up survey was made in 2007. Regression analyses with odds ratios and 95% confidence intervals were calculated. During the 5- to 7-year follow-up, 26% of women and 24% of men gained in weight 5 kg or more. Working conditions were mostly unassociated with weight gain. However, nighttime shift work, physical threat at work, and hazardous exposures at work were moderately associated with weight gain. More attention should be devoted to the prevention of weight gain in general and among risk groups in particular.

    Introduction: Rural residents of the United States (US) and Canada face problems in accessing healthcare. International medical graduates (IMGs) play an important role in delivering rural healthcare. IMGs from Caribbean medical schools have the highest proportion of physicians in primary care.  Xavier University School of Medicines admits students from the US, Canada and other countries to the undergraduate medical (MD) course and also offers a premedical program. The present study was conducted to obtain student perception about working in rural US/Canada after graduation.   Methods: The study was conducted among premedical and preclinical undergraduate medical (MD) students during October 2014. The questionnaire used was modified from a previous study. Semester of study, gender, nationality, place of residence and occupation of parents were noted. Information about whether students plan to work in rural US/Canada after graduation, possible reasons why doctors are reluctant to work in rural areas, how the government can encourage rural practice, possible problems respondents anticipate while working in rural areas were among the topics studied. Results: Ninety nine of the 108 students (91.7%) participated. Forty respondents were in favor of working in rural US/Canada after graduation. Respondents mentioned good housing, regular electricity, water supply, telecommunication facilities, and schools for education of children as important conditions to be fulfilled. The government should provide higher salaries to rural doctors, help with loan repayment, and provide opportunities for professional growth.  Potential problems mentioned were difficulty in being accepted by the rural community, problems in convincing patients to follow medical advice, lack of exposure to rural life among the respondents, and cultural issues. Conclusions: About 40% of respondents would consider working in rural US/Canada. Conditions required to be fulfilled have been mentioned above

    Blind Australians find great difficulty in recognising bank notes. Each note has the same feel, with no Braille markings, irregular edges or other tangible features. In Australia, there is only one device available that can assist blind people recognise their notes. Internationally, there are devices available; however they are expensive, complex and have not been developed to cater for Australian currency. This paper discusses a new device, the MoneyTalker that takes advantage of the largely different colours and patterns on each Australian bank note and recognises the notes electronically, using the reflection and transmission properties of light. Different coloured lights are transmitted through the inserted note and the corresponding sensors detect distinct ranges of values depending on the colour of the note. Various classification algorithms were studied and the final algorithm was chosen based on accuracy and speed of recognition. The MoneyTalker has shown an accuracy of more than 99%. A blind subject has tested the device and believes that it is usable, compact and affordable. Based on the devices that are available currently in Australia, the MoneyTalker is an effective alternative in terms of accuracy and usability.

    A previous case-control study which used the occupational information available on the New Zealand Cancer Registry found that agricultural workers were at increased risk of developing non-Hodgkin's lymphoma. The findings are now presented for the second phase of the study which entailed interviewing 83 cases of non-Hodgkin's lymphoma registered under code 202 of the International Classification of Diseases together with 168 controls with other types of cancer and 228 general population controls. The findings for the two control groups were similar, and there were no significant differences between cases and controls regarding potential exposure to phenoxy-herbicides (odds ratio = 1.4, 90% confidence limits 0.7-2.5, p = 0.26) or chlorophenols (odds ratio = 1.3, 90% confidence limits 0.6-2.7, p = 0.39). The odds ratio for fencing work, necessitating exposure to several potential risk factors including arsenic and sodium pentachlorophenate was 2.0 (90% confidence limits 1.3-3.0, p = 0.01). The odds ratio for employment in a meat works, necessitating potential exposure to 2, 4, 6-trichlorophenol and zoonotic viruses, was 1.8 (90% confidence limits 1.1-3.1, p = 0.04). There was a significant statistical interaction between the risks associated with these two activities, the odds ratio for involvement in both activities compared with involvement in neither being 5.7 (90% confidence limits 2.3-14.3, p = 0.03).

    In previous work, I allowed students in my introductory physics course to write note sheets to prepare for exams, and I analyzed the contents as a way of determining what students saw as important in my course. In the present study, I tried a new note sheet approach where I supplied some equations for their notes in advance, thinking that doing so would focus students on other important conceptual aspects of the course. In all cases, I gave a brief survey to get student perspectives on their exam preparation. In addition, I introduced an online pre-exam forum asking students to respond to two short questions about how they might prepare their notes for the exam.

    X-ray source based on electron cyclotron resonance principle has been constructed using TE{sub 111} cylindrical cavity. At present the device is used to provide low energy x-ray field for thermoluminescent dosimeter badge calibration. Theoretical and experimental studies on the effect of target placement inside the TE{sub 111} cylindrical cavity for enhancing the x-ray output are carried out and the results are presented in this note. Optimum target location is identified by theoretical analysis on the electric field distribution inside the cavity using MICROWAVE STUDIO program. By modifying the magnetic field configuration, the resonance region is shifted to the optimum target location. The microwave transmission line is upgraded with a three stub tuner which improves the microwave coupling from the source to the target loaded cavity. Molybdenum target is located at a radial distance of 2.5 cm from the cavity center and the x-ray dose rate is measured at 20 cm from the exit port for different microwave power. With the introduction of the target, the x-ray output has improved nearly from 70% to 160% in the microwave power of 150-500 W.

    1998-01-01

    This short note provides some additional insight into how the HARP program works. In some cases, it is possible for HARP to tdm away too many states and obtain an optimistic result. The HARP Version 7.0 manual warns the user that 'Unlike the ALL model, the SAME model can automatically drop failure modes for certain system models. The user is cautioned to insure that no important failure modes are dropped; otherwise, a non-conservative result can be given.' This note provides an example of where this occurs and a pointer to further documentation that gives a means of bounding the error associated with trimming these states.

    NASA Astrophysics Data System (ADS)

    Bonner, Janice M.; Holliday, William G.

    2006-10-01

    A composite theory of college science student note-taking strategies was derived from a periodic series of five interviews with 23 students and with other variables, including original and final versions of notes analyzed during a semester-long genetics course. This evolving composite theory was later compared with Van Meter, Yokoi, and Pressley's (Journal of Educational Psychology, 86, 323-338, 1994) corresponding composite college students' theory of note-taking. Students' notes in this long-term study were also compared with a standard of adequate note-taking established by experts. Analyses detected many similarities between the two composite theories. Analyses also provided evidence of inadequate note-taking strategies, inconsistencies between what students claimed and evidently did with their notes, and weak self-regulating learning strategies. Recommendations included prompting students during class on how to take notes.

    2011-05-01

    An important first step in characterizing a vocalization is to classify, describe, and measure the elements of that vocalization. Here, this methodology is employed to study the chick-a-dee call of the boreal chickadee (Poecile hudsonicus). The note types (A, B, C, D, and D(h)) in a sample of boreal chickadee calls are identified and described, spectral and temporal features of each note type are analyzed, and production phenomena in each note type are identified and quantified. Acoustic variability is compared across note types and individuals to determine potential features used for note-type and individual discrimination. Frequency measures appear to be the most useful features for identifying note types and individuals, though total duration may also be useful. Call syntax reveals that boreal chick-a-dee calls follow a general rule of note-type order, namely A-B-C-D(h)-D, and that any note type in this sequence may be repeated or omitted. This work provides a thorough description of the boreal chickadee chick-a-dee call and will serve as a foundation for future studies aimed at elucidating this call's functional significance within this species, as well as for studies comparing chick-a-dee calls across Poecile species.

  13. Night work and mortality: prospective study among Finnish employees over the time span 1984 to 2008.

    There is considerable evidence showing that night work is associated with increased morbidity, but only a few studies have focused on its relation to mortality. This study investigates the relationship between the type of working-time arrangement (weekly night work/daytime work) and total and cause-specific mortality among men and women. The data consist of a representative working conditions survey of Finnish employees conducted in 1984 (2286 men/2216 women), which has been combined with register-based follow-up data from Statistics Finland covering the years 1985-2008. In the 1984 survey, the employees were asked if they worked during the night (23:00-06:00 h) and if so, how often. In this study, the authors compare employees who worked at night (121 men/89 women) to daytime employees who did not do night work (1325 men/1560 women). The relative risk of death was examined by Cox proportional hazards analyses adjusted for background (age, level of education, family situation, and county), health (longstanding illness, pain symptoms, smoking status, and psychological symptoms), and work-related factors (weekly working hours, physical and psychological demands, demands of learning at work, and perceived job insecurity). Female employees working at night had a 2.25-fold higher risk of mortality than female dayworkers (95% confidence interval [CI] 1.20-4.20) after adjustment for background and health- and work-related factors. In addition to total mortality, night work was also associated with tumor mortality. Female night workers had a 2.82-fold higher risk of tumor mortality than female dayworkers (95% CI 1.20-6.65) in the adjusted model. Among men, no such significant association was observed. The present study indicated that female night workers had a higher risk of both total and tumor mortality compared to female daytime employees. Additional research on the potential factors and mechanisms behind the association between night work and mortality is required.

    2012-01-01

    In 2010 15.2% of the work force in the Netherlands works with a computer at another location than at the office or at the clients' location. 27% of the Dutch working population is not satisfied about the possibility to work at home and 18% is not satisfied on the possibility to plan your own working time. The case control study affirms what has been reported as effects of new ways of work: the experienced productivity by communication and the representativeness of the office interior are improved and attention is needed for workers that need concentration space and need to personalize their work environment. In implementing new ways of work these issues need attention.

    Nota, Laura; Ginevra, Maria Cristina

    2014-01-01

    The present work examines how a group of Italian parents and their adolescent children view work, study, and leisure in order to check for possible relations between the ideas of parents and their children's. A total of 160 adolescents and 160 parents were recruited. Semi-structured interviews that assessed the participants' concepts about work, study, and leisure were conducted. The analyses carried out demonstrate that there are connections between the parents' and adolescents' perceptions regarding work, study, and leisure. The results confirm the importance of considering both constructs and the parents' perspectives on them, and of involving parents in their children vocational guidance actions.

    The work breakdown structure (WBS) for the Payload Specialist Station (PSS) is presented. The WBS is divided into two elements--PSS contractor and mission unique requirements. In accordance with the study ground rules, it is assumed that a single contractor, hereafter referred to as PSS Contractor will perform the following: (1) provide C and D hardware (MFDS and elements of MMSE), except for GFE; (2) identify software requirements; (3) provide GSE and ground test software; and (4) perform systems engineering and integration in support of the Aft Flight Deck (AFD) C and D concept. The PSS Contractor WBS element encompasses a core or standardized PSS concept. Payload peculiar C and D requirements identified by users will originate as a part of the WBS element mission unique requirements; these requirements will be provided to the PSS Contractor for implementation.

  5. Is working in culturally diverse working environment associated with physicians' work-related well-being? A cross-sectional survey study among Finnish physicians.

    2014-08-01

    International mobility of health care professionals is increasing, though little is known about how working in a culturally diverse team affects the native physicians' psychosocial work environment. We examined Finnish physicians' perceptions of work-related wellbeing according to whether they had foreign-born colleagues (FBCs) in their work unit. We also examined whether work-related resources moderate the potential association between work-related wellbeing and working alongside FBCs. A cross-sectional survey was conducted for a random sample of physicians in Finland in 2010 (3826 respondents, response rate 55%). Analyses were restricted to native Finnish physicians working in public health care. The results were analyzed by ANCOVA. In unadjusted analyses, having FBCs was related to poor team climate (p<0.001) and poor job satisfaction (p=0.001). Those physicians who reported high procedural justice and high job control perceived also higher job satisfaction even if they had many FBCs in the work unit (p=0.007 for interaction between FBCs and procedural justice and p<0.001 for interaction between FBCs and job control). These associations were robust to adjustments for age, sex, health care sector, specialization, on-call duty, employment contract, full-time employment and leadership position. The results indicate that culturally diverse work units face challenges related to team climate and job satisfaction. The results also show that leadership plays an important role in culturally diverse work units. The potential challenges of culturally diverse teams for native physicians may be reduced by fair decision-making and by increasing physicians' job control.

  6. Technical Note: Phantom study to evaluate the dose and image quality effects of a computed tomography organ-based tube current modulation technique

    2015-11-15

    Purpose: This technical note quantifies the dose and image quality performance of a clinically available organ-dose-based tube current modulation (ODM) technique, using experimental and simulation phantom studies. The investigated ODM implementation reduces the tube current for the anterior source positions, without increasing current for posterior positions, although such an approach was also evaluated for comparison. Methods: Axial CT scans at 120 kV were performed on head and chest phantoms on an ODM-equipped scanner (Optima CT660, GE Healthcare, Chalfont St. Giles, England). Dosimeters quantified dose to breast, lung, heart, spine, eye lens, and brain regions for ODM and 3D-modulation (SmartmA) settings. Monte Carlo simulations, validated with experimental data, were performed on 28 voxelized head phantoms and 10 chest phantoms to quantify organ dose and noise standard deviation. The dose and noise effects of increasing the posterior tube current were also investigated. Results: ODM reduced the dose for all experimental dosimeters with respect to SmartmA, with average dose reductions across dosimeters of 31% (breast), 21% (lung), 24% (heart), 6% (spine), 19% (eye lens), and 11% (brain), with similar results for the simulation validation study. In the phantom library study, the average dose reduction across all phantoms was 34% (breast), 20% (lung), 8% (spine), 20% (eye lens), and 8% (brain). ODM increased the noise standard deviation in reconstructed images by 6%–20%, with generally greater noise increases in anterior regions. Increasing the posterior tube current provided similar dose reduction as ODM for breast and eye lens, increased dose to the spine, with noise effects ranging from 2% noise reduction to 16% noise increase. At noise equal to SmartmA, ODM increased the estimated effective dose by 4% and 8% for chest and head scans, respectively. Increasing the posterior tube current further increased the effective dose by 15% (chest) and 18% (head

    Summary Objective To describe doctors' views on, and responses to, their professional working lives in the UK National Health Service (NHS). Design Qualitative study using semi structured interviews. Setting Two district hospitals and primary care settings in the North of England. Participants Fifty-two doctors participated in the study – 47 worked in hospital and five worked in general practice. Main outcome measures Qualitative information regarding doctors' views on their working lives. Results The study provided insights into the views of their working lives of a sample of doctors in the NHS. Feelings they articulated contained a number of ambivalences. Feelings about the future were coloured by concerns about the impact of regulatory changes and processes of modernization on the experiential knowledge of doctors. Conclusions These insights into doctors' views of their working lives might usefully inform those involved in the planning and overseeing of changes to health service structures and systems.

  10. Zest for work? Assessment of enthusiasm and satisfaction with the present work situation and health--a 1.5-year follow-up study.

    PubMed

    Josephson, Malin; Vingård, Eva

    2007-01-01

    The aim of the study was to investigate whether assessing zest for work is a valuable approach in occupational health work. The term "zest for work" comes from the expression "zest for life" and can roughly be interpreted as the degree of enthusiasm and satisfaction with the present work situation. The measurements comprise three components: listing important factors for the feeling of zest for work, attitude rating and stating whether it is possible to have any influence over the listed factors. Included in this study were 5539 employees, mainly women. Low zest for work was associated with job strain and insufficient social support and imposed an increased risk for poor health for working and long spells of sick leave. The results support that assessing zest for work can be useful in occupational health work.

    Allergic rhinitis often impairs social life and performance. The aim of this cross-sectional study was to assess the impact of uncontrolled rhinitis assessed by visual analogue score VAS on work productivity using cell phone data collection. A mobile phone app Allergy Diary, Android and Apple stores collects daily visual analogue scales VAS data for overall allergic symptoms VAS-global measured, nasal VAS-nasal, ocular VAS-ocular, asthma symptoms VAS-asthma and work VAS-work. A combined nasal-ocular score is calculated. Allergy Diary is available in 20 countries. The App includes the Work Productivity and Activity Impairment Allergic Specific Questionnaire WPAI:AS questionnaire in 6 EU countries. All consecutive users who filled the VAS-work from June 1 to October 31, 2016 were included in the study. A total of 1,136 users filled in 5,818 days of VAS-work. Symptoms of allergic rhinitis were controlled VAS-global<20 in approximately 60% of days. In users with uncontrolled rhinitis, approximately 90% had some work impairment and over 50% had severe work impairment VAS-work>50. There was a significant correlation between VAS-global calculated and VAS-work Rho=0.83, p<0.00001, Spearman rank test. In 144 users, there was a significant correlation between VAS-work and WPAI:AS Rho=0.53, p<0.0001. This article is protected by copyright. All rights reserved.

    2015-07-01

    The present study aimed to advance insight in the associations between employees' daily effort expenditure at work and their recovery state during the workday, and specifically focused on the role of daily work-related need satisfaction in this process. We examined (a) if high intrinsic work motivation and low self-control effort act as mediating mechanisms underlying the beneficial role of need satisfaction, and (b) to what extent need satisfaction mitigates the adverse effects of high job demands (work pressure and cognitive demands) on employee recovery. Data were collected by means of a 5-day daily diary study (2 measurements daily: in the morning before work, and at the end of the workday) among 68 participants. Multilevel analyses showed that need satisfaction at work was related to a beneficial recovery state at the end of the workday, and that this association was mediated by high intrinsic work motivation and low self-control effort. Furthermore, need satisfaction attenuated the adverse effects of high work pressure on employee recovery. All in all, this study increased our understanding of employees' daily effort and recovery processes at work, and highlighted the beneficial role of need satisfaction at work.

    Progress is reported in a program whose objective is to develop an underground superconducting power transmission system which is economical and technically attractive to the utility industry. The system would be capable of carrying very large blocks of electric power, and would supplant overhead lines in urban and suburban areas and regions of natural beauty. The program consisted initially of work in the laboratory to develop suitable materials, cryostats, and cable concepts. The materials work covers the development and testing of suitable superconductors and dielectric insulation. The laboratory work has now been extended to an outside test facility which represents an intermediate step between the laboratory scale and a full-scale system. The facility will allow cables several hundred feet long to be tested under realistic conditions. In addition, the refrigerator has been designed for optimum service for utility applications.

    Recent longitudinal investigations of professional socialisation and development of professional behaviours during work-based training are lacking. Using longitudinal mixed methods, this study aimed to explore the development of professional behaviours during a year of intensive work-based (pre-registration) training in pharmacy. Twenty trainee pharmacists and their tutors completed semi-structured interview and professional behaviour questionnaires at four time points during 2011/2012: months 1, 4 and 9 during training and 4 months after registration; tutors participated in months 1 and 9. Interviews were analysed thematically using template analysis, and questionnaires were analysed using ANOVA and t-tests. Self-assessed (trainee) and tutor ratings of all elements of professional behaviours measured in questionnaires (appearance, interpersonal/social skills, responsibility, communication skills) increased significantly from the start of pre-registration training to post-registration. Some elements, for example, communication skills, showed more change over time compared with others, such as appearance, and continued to improve post-registration. Qualitative findings highlighted the changing roles of trainees and learning experiences that appeared to facilitate the development of professional behaviours. Trainees' colleagues, and particularly tutors, played an essential part in trainees' development through offering support and role modelling. Trainees noted that they would have benefited from more responsibilities during training to ease the transition into practising as a responsible pharmacist. Longitudinal mixed methods can unpack the way in which professional behaviours develop during work-based training and allow researchers to examine changes in the demonstration of professional behaviours and how they occur. Identifying areas less prone to change allows for more focus to be given to supporting trainees in areas where there is a development need, such as

  16. Social Consequences of Nomadic Working: A Case Study in an Organization

    NASA Astrophysics Data System (ADS)

    Singh, Ramanjit; Wood-Harper, Trevor

    This research study identified social challenges that knowledge workers in the Swedish organization TeliaSonera (Telia) face when utilizing wireless technologies to conduct work on the move. Upon collecting the relevant research data, five problem areas were identified: work and life balance, addiction, organizational involvement, nomadic work and control, and individual productivity. Each problem area was examined with the philosophical underpinning of socio-technical design principles. The results confirm that better role boundary management, self-discipline, work negotiation, and e-mail communication skills may be required for the knowledge workers to manage the demands of nomadic working. Similarly, rewarding nomadic work performance, building employee supervisor trust relations, and designing jobs that enhance work and life balance can be imperative.

  1. Mental health, constraints, and organization of work as interactive variables. A study of word processing secretaries.

    PubMed

    1992-07-01

    The effect of a work constraint is specific to the type of work organization. This article deals with the effects of different types of work organization on the mental health of secretaries. The advantage of choosing secretarial work as a research subject lies in the fact that we can identify three distinct types of work organization: (1) a secretary working directly for someone (the "paired" secretary-boss), (2) the "pool," geared toward keyboard input with no specific pairing of secretaries and authors, and (3) the departmental "team," a hybrid of the two preceding types, characterized by the presence of several secretaries, each one assigned to several authors. A study was conducted on the health problems reported by secretaries in the Québec civil service. Data available from a Santé Québec study, carried out at the same time, allowed us to constitute a general population reference group of secretaries and other working women. The findings indicate that secretaries in the general population are no more at risk than are other similar working women, but that secretaries in the provincial civil service are at risk. Regression analysis shows that the same traditional constraints do not affect secretaries in the same way regardless of whether they are members of pair, pool, or team organizations. This suggests that the context of work organization is an interactive or a "specifying variable" of the effect of work constraints on the secretaries' mental health.

    2017-01-01

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

    Sleep problems are a well-known risk factor for work injuries, but less is known about which vulnerable populations are most at risk. The aims of this study were to investigate the association between sleep quality and the risk of work injury and to identify factors that may modify the association. A case-control study including 180 cases and 551 controls was conducted at the University Hospital in Basel, Switzerland, from 1 December 2009 to 30 June 2011. Data on work injuries and sleep quality were collected. Adjusted odds ratios and 95% confidence intervals of the association between sleep quality and work injury were estimated in multivariable logistic regression analyses and were stratified by hypothesized effect modifiers (age, gender, job risk, shift work, sleep duration and working hours). Poor sleep quality was associated significantly with work injury of any type (P < 0.05) and with being caught in particular (P < 0.05). The association between poor sleep quality and work injury was significantly higher for workers older than 30 years (odds ratio>30 1.30 versus odds ratio≤30 0.91, P < 0.01), sleeping 7 h or less per night (odds ratio≤7 1.17 versus odds ratio>7 0.79, P < 0.05) and working 50 h or more per week (odds ratio≥50 1.79 versus odd ratio<50 1.10, P < 0.01). Work injury risk increased with increasing severity of sleep problems (P < 0.05). Prior work injury frequency increased with decreasing sleep quality (P < 0.05). Older age, short sleep duration and long working hours may enhance the risk of work injuries associated with sleep quality.

    Objective An increasing number of patients in the working population are undergoing total knee replacement (TKR) for end-stage osteoarthritis. The timing and success of return to work is becoming increasingly important for this group of patients with social and economic implications for patients, employers and society. There is limited understanding of the patient variables that determine the ability to return to work. Our objective was (from the patient's perspective) to gain an insight into the factors influencing return to work following knee replacement. Setting and participants This qualitative study was undertaken in a secondary-care setting in a large teaching hospital in the north of England. Semistructured interviews were carried out with 10 patients regarding their experiences of returning to work following TKR. Outcomes Interviews were transcribed and analysed using a qualitative thematic approach to identify the factors influencing return to work from the patient's perspective. Results Three themes were identified that influenced the process of return to work, from the patient's perspective. These were delays in surgical intervention, limited and often inconsistent advice from healthcare professionals regarding return to work, and finally the absence of rehabilitation to optimise patient's recovery and facilitate return to work. Conclusions There is currently no consistent process to optimise return to work for patients of working age after TKR. The impact of delayed surgical intervention, limited advice regarding return to work, and a lack of work-focused rehabilitation, all contribute to potential delays in successful return to work. There is a need to change the focus of healthcare provision for this cohort of patients, and provide a tailored healthcare intervention to optimise patient outcomes. PMID:26832426

  12. Synthesis of Nanosilver Particles in the Texture of Bank Notes to Produce Antibacterial Effect

    Lari, Mohammad Hossein Asadi; Esmaili, Vahid; Naghavi, Seyed Mohammad Ebrahim; Kimiaghalam, Amir Hossein; Sharifaskari, Emadaldin

    Silver particles show antibacterial and antiseptic properties at the nanoscale. Such properties result from an alteration in the binding capacity of silver atoms in bits of less than 6.5nm which enables them to kill harmful organisms. Silver nanoparticles are now the most broadly used agents in the area of nanotechnology after carbon nanotubes. Given that currency bills are one of the major sources of bacterial disseminations and their contamination has recently been nominated as a critical factor in gastrointestinal infections and possibly colon cancers, here we propose a new method for producing antibacterial bank notes by using silver nanoparticles. Older bank notes are sprayed with acetone to clean the surface. The bank note is put into a petri-dish containing a solution of silver nitrate and ammonia so that it is impregnated. The bank notes are then reduced with the formaldehyde gas, which penetrates its texture and produces silver nanoparticles in the cellulose matrix. The side products of the reactions are quickly dried off and the procedure ends with the drying of the bank note. The transmission electron microscope (TEM) images confirmed the nanoscale size range for the formed particles while spectroscopy methods, such as XRD, provided proof for the metallic nature of the particles. Bacterial challenge tests then showed that no colonies of the three tested bacterium (Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa survived on the sample after a 72h incubation period. This study has provided a method for synthesizing silver NPs directly into the texture of fabrics and textiles (like that of bank notes) which can result in lower production costs, making the use of silver NPs economically beneficial. The method, specifically works on the fabric of bank notes, suggesting a method to tackle the transmission of bacteria through bank notes. Moreover, this study is a testament to the strong antibacterial nature of even low concentrations of

    Accurate reporting of personal dose is required by regulation for hospital personnel that work with radioactive material. Pocket dosimeters are commonly used for monitoring this personal dose. We show that operating a cell phone in the vicinity of a pocket dosimeter can introduce large and erroneous readings of the dosimeter. This note reports a systematic study of this electromagnetic interference. We found that simple practical measures are enough to mitigate this problem, such as increasing the distance between the cell phone and the dosimeter or shielding the dosimeter, while maintaining its sensitivity to ionizing radiation, by placing it inside a common anti-static bag.

    2013-12-01

    Self-concordant work motivation arises from one's authentic choices, personal values, and interests. In the present study, we investigated whether self-concordant motivation may fluctuate from one work-related task to the next. On the basis of self-determination theory, we hypothesized that momentary self-concordance buffers the negative impact of momentary work demands on momentary happiness. We developed a modified version of the day reconstruction method to investigate self-concordance, work demands, and happiness during specific work-related tasks on a within-person and within-day level. In total, 132 teachers completed a daily diary on three consecutive work days as well as a background questionnaire. The daily diary resulted in 792 reported work activities and activity-related work demands, self-concordance, and happiness scores. Multilevel analysis showed that-for most work activities-state self-concordant motivation buffered the negative association of work demands with happiness. These findings add to the literature on motivation and well-being by showing that the levels of self-concordance and happiness experienced by employees vary significantly on a within-day level and show a predictable pattern. We discuss theoretical and practical implications of the findings to increase employees' well-being.

    The objective of the present study was to investigate if satisfaction of the basic needs of autonomy, competence, and relatedness is related to shift work tolerance, specifically physical and mental fatigue, insomnia, and digestive troubles in a sample of shift workers. This is a cross-sectional pilot questionnaire study, including 252 shift workers employed in a municipality in Norway. Autonomy was negatively related to physical fatigue and digestive troubles, while competence was negatively related to mental fatigue. Relatedness showed significant correlations with insomnia and mental fatigue, but did not reach significance in the regression model controlling for the two other basic needs as well as work scheduling, night work exposure, and sleep medication. Sleep medication was significant in the final regression model for insomnia, but unrelated to fatigue and digestive troubles. The demographic variables, work hours per week, work schedule, and night work exposure were unrelated to all four measures of shift work tolerance. Autonomy and competence may be more important for fatigue and digestive troubles among shift workers than work arrangement variables, night work exposure, and sleep medication use.

    Fatigue is a symptom of arthritis that causes difficulty at work. An improved understanding of this symptom could assist its management in the work environment. The aim of this study was to explore people with rheumatic diseases’ experiences of fatigue in work. A qualitative descriptive design was used with semi-structured interviews and a constant comparative method of data analysis. There were 18 participants, the majority of them female with Rheumatoid Arthritis (RA) and working full-time. Three themes were identified: “Impact of fatigue on work performance” with cognition, mood and physical abilities being the main difficulties reported. In the second theme “Disclosure at Work” participants discussed disclosing their disease to employers but reported a lack of understanding of fatigue from colleagues. The final theme “work-based fatigue management strategies” included cognitive strategies and energy management techniques, which were mainly self-taught. In this study, fatigue was reported to impact on many areas of work performance with limited understanding from colleagues and employers. Interventions from health professionals to assist with development of work-related self-management skills are required to assist with symptom management in the work place. Such interventions should include education to employers and colleagues on the nature of fatigue in Rheumatic diseases. PMID:26516896

    This work presents the initial steps of ergonomic analysis of industrial activities, which are being held in the premises of an Agricultural Experimental farm belonging to an institution of higher education. The methods employed in the initial step was confined to desk research, its purpose was to know the demographic profile and understand organizational structure followed by systematic observations in workplaces using semi-structured interviews and a questionnaire of perception to operators. The presentation of the results will provide a summary of the analysis of activity sectors visited, understanding the biomechanical efforts entered (posture and strength), as well as the evaluation according to the perception of officials to respect the constraints, ambience and suggestions. It was noted that 90% of employees surveyed feel some kind of discomfort. It also highlights the age factor of this questionnaire, in which the majority (90%) is above 40 years old, and this fact confirms and reinforces the appearance or accumulation of injuries among the employers. At this stage there was no intention to deploy improvements, but create assumptions and guide future intervention actions that can be performed.

    2007-01-01

    Despite research on work and health having a long-standing concern about unjust exposures and inequitable burdens of disease, there are few studies that document the joint distribution and health effects of physical and psychosocial hazards (e.g., noise, dusts, fumes, and job strain) and social hazards (e.g., racial discrimination and gender harassment) encountered at work. Also, there is a paucity of data on how these exposures, singly and combined, are distributed in relation to sociodemographic characteristics including race/ethnicity, gender, socioeconomic position, and nativity. This article presents a conceptual model for redressing these knowledge gaps and describes recruitment strategies and the characteristics of study participants in the United for Health study. Working with labor unions, the authors recruited 14 (67%) of 21 worksites from manufacturing, meat processing, retail, and transportation, and 1,282 workers (72% response rate), of whom 62 percent were men, 36 percent were women, 39 percent were black, 23 percent were Hispanic, 25 percent were white, 31% earned less than a living wage, 40 percent were below the poverty level, and 23 percent had less than a high school education.

    2012-01-01

    The current study aims at evaluating the reorganization of work processes on the basis of studies of three assembly lines in a well known component manufacture of the German automotive industry. It is of particular interest to evaluate the impact of the introduction of Chaku-Chaku assembly lines on the production goals, distribution of activities during one typical work day and psychosocial characteristics of the work environment. Findings indicate that the Chaku-Chaku assembly lines could represent a successful production strategy in order to enhance the output levels of work systems. However, the data show that interviewed assembly workers have spent more time on value added activities than before. The intensive perception of the time spent on main work activities (direct value added activities) and a simultaneous decrease of available discretionary time between work tasks seem to be related to the low level of the reported psychosocial work characteristics.

    Objectives This study aimed to analyse and compare differences in occupational stress, depressive symptoms, work ability and working environment among residents working in various medical specialties. Methods 435 German hospital residents in medical training working in 6 different medical specialties participated in a cross-sectional survey study. Physicians were asked about their working conditions and aspects of mental health and work ability. The Copenhagen Psychosocial Questionnaire, the Work Ability Index, the ICD-10 Symptom Rating and the Perceived Stress Questionnaire were used to measure working conditions, mental health and work ability. Results Results show that up to 17% of the physicians reported high levels of occupational distress and 9% reported high levels of depressive symptoms. 11% of the hospital physicians scored low in work ability. Significant differences between medical specialties were demonstrated for occupational distress, depressive symptoms, work ability, job demands and job resources. Surgeons showed consistently the highest levels of perceived distress but also the highest levels of work ability and lowest scores for depression. Depressive symptoms were rated with the highest levels by anaesthesiologists. Significant associations between physicians’ working conditions, occupational distress and mental health-related aspects are illustrated. Conclusions Study results demonstrated significant differences in specific job stressors, demands and resources. Relevant relations between work factors and physicians' health and work ability are discussed. These findings should be reinvestigated in further studies, especially with a longitudinal study design. This work suggests that to ensure physicians' health, hospital management should plan and implement suitable mental health promotion strategies. In addition, operational efficiency through resource planning optimisation and work process improvements should be focused by hospital management

    Experimental studies in animals indicate that disruption of the circadian rhythm is carcinogenic, and night work has been suggested to be a probable breast cancer cause in humans. Findings among humans, however are inconsistent, often gathered with retrospective study designs, and only based on specific populations, such as nurses. We used data on night work collected in the Dutch Labor Force Surveys of 1996 until 2009, and individually linked these with National registers on hospital admission. Among 285,723 women without breast cancer at baseline, 2,531 had a hospital admission for breast cancer during an average of 7 years of follow up in the registers. Occasional and regular night work were not associated with the risk of hospital admission for breast cancer (adjusted hazard ratios 1.04; 95 % confidence interval 0.85-1.27, and 0.87; 0.72-1.05, respectively). Working more hours per week, or more years in a job entailing night work did not show increased breast cancer risks. Hazard ratios neither differed between nurses and women with other occupations. Our results show no association of night work with incident breast cancer, and suggest that night work generally does not increase the risk of breast cancer among women in the Dutch working population.

    Background The increasing economic pressure characterizes the current situation in health care and the need to justify medical decisions and organizational processes due to limited financial resources is omnipresent. Physicians tend to interpret this development as a decimation of their own medical influence. This becomes even more obvious after a change in hospital ownership i.e. from a public to a private profit oriented organization. In this case each work procedure is revised. To date, most research studies have focused mainly on differences between hospitals of different ownership regarding financial outcomes and quality of care, leaving important organizational issues unexplored. Little attention has been devoted to the effects of hospital ownership on physicians' working routines. The aim of this observational real time study is to deliver exact data about physicians' work at hospitals of different ownership. Methods The consequences of different management types on the organizational structures of the physicians' work situation and on job satisfaction in the ward situation are monitored by objective real time studies and multi-level psycho diagnostic measurements. Discussion This study is unique in its focus. To date no results have been found for computer-based real time studies on work activity in the clinical field in order to objectively evaluate a physician's work-related stress. After a complete documentation of the physicians' work processes the daily work flow can be estimated and systematically optimized. This can stimulate an overall improvement of health care services in Germany. PMID:19505318

    The National Probation Service in England and Wales currently delivers community-based accredited offending behavior programs in mixed-gender groups. There is at present a lack of research on the potential impact of mixed-gender group work on female offenders, who are often the minority within the group. This study aimed to improve our understanding of the area using qualitative methods. Sixteen offenders who had participated in a mixed-gender offending behavior program were interviewed as part of this study. Themes from the interviews were analyzed using Grounded Theory techniques. The findings illustrated an overall preference among all participants for mixed-gender rather than single-gender group work. The specific advantages of mixed-gender group work included increased learning about the opposite sex and a more relaxed atmosphere within the group. Although this study reflects positive attitudes to mixed-gender group work, the findings need to be tested further using empirical methodology.

    Computer work is characterized by sedentary static workload with low-intensity energy metabolism. The aim of our study was to evaluate the dynamics of skin surface temperature in the hand during prolonged computer mouse work under different ergonomic setups. Digital infrared imaging of the right forearm and wrist was performed during three hours of continuous computer work (measured at the start and every 15 minutes thereafter) in a laboratory with controlled ambient conditions. Four people participated in the study. Three different ergonomic computer mouse setups were tested on three different days (horizontal computer mouse without mouse pad; horizontal computer mouse with mouse pad and padded wrist support; vertical computer mouse without mouse pad). The study revealed a significantly strong negative correlation between the temperature of the dorsal surface of the wrist and time spent working with a computer mouse. Hand skin temperature decreased markedly after one hour of continuous computer mouse work. Vertical computer mouse work preserved more stable and higher temperatures of the wrist (>30 °C), while continuous use of a horizontal mouse for more than two hours caused an extremely low temperature (<28 °C) in distal parts of the hand. The preliminary observational findings indicate the significant effect of the duration and ergonomics of computer mouse work on the development of hand hypothermia.

    Background: Volunteers are an integral part of the palliative care services in the Tata Memorial Hospital, Mumbai, Maharashtra, India. These volunteers are an important resource for the department. Thus, it is necessary for the department to determine what motivates these volunteers to continue to work in the setting, acknowledge them and direct efforts toward retaining them and giving them opportunities to serve to the best of their desire and abilities. Aims: The current study aimed at understanding the motivation of volunteers to work in palliative care, to identify the challenges they face and also the effect of their work on their self and relationships. Methodology: In-depth interviews were conducted using semistructured interview guide to study above mentioned aspects. Themes were identified and coding was used to analyze the data. Results: The results suggested that the basic motivation for all the volunteers to work in a palliative care setting is an inherent urge, a feeling of need to give back to the society by serving the sick and the suffering. Other motivating factors identified were team spirit, comfort shared, warm and respectful treatment by the team, satisfying nature of work, experience of cancer in the family, and aligned values and beliefs. Some intrinsic rewards mentioned by volunteers were joy of giving, personal growth, enriching experiences, and meaningful nature of work. Conclusion: The study attempted to improve opportunities of working for these volunteers. Although limited in scope, it offers insight for future research in the area of volunteerism in palliative care setup. PMID:27559267

    Previous studies linked heavy computer use to disturbed sleep. This study investigates the association between computer use during work and leisure and sleep problems in working adults. From the 2010 round of the Danish Work Environment Cohort Study, currently employed wage earners on daytime schedule (N = 7883) replied to the Bergen insomnia scale and questions on weekly duration of computer use. Results showed that sleep problems for three or more days per week (average of six questions) were experienced by 14.9% of the respondents. Logistic regression analyses, controlled for gender, age, physical and psychosocial work factors, lifestyle, chronic disease and mental health showed that computer use during leisure for 30 or more hours per week (reference 0-10 hours per week) was associated with increased odds of sleep problems (OR 1.83 [95% CI 1.06-3.17]). Computer use during work and shorter duration of computer use during leisure were not associated with sleep problems. In conclusion, excessive computer use during leisure - but not work - is associated with sleep problems in adults working on daytime schedule.

    The authors evaluated the association of complexity of work with data, people, and things with the incidence of dementia, Alzheimer's disease, and vascular dementia in the Canadian Study of Health and Aging, while adjusting for work-related physical activity. The Canadian Study of Health and Aging is a 10-year population study, from 1991 to 2001, of a representative sample of persons aged 65 years or older. Lifetime job history allowed application of complexity scores and classification of work-related physical activity. Analyses included 3,557 subjects, of whom 400 were incident dementia cases, including 299 with Alzheimer's disease and 93 with vascular dementia. In fully adjusted Cox regression models, high complexity of work with people or things reduced risk of dementia (hazard ratios were 0.66 (95% confidence interval: 0.44, 0.98) and 0.72 (95% confidence interval: 0.52, 0.99), respectively) but not Alzheimer's disease. For vascular dementia, hazard ratios were 0.36 (95% confidence interval: 0.15, 0.90) for high complexity of work with people and 0.50 (95% confidence interval: 0.25, 1.00) for high complexity of work with things. Subgroup analyses according to median duration (23 years) of principal occupation showed that associations with complexity varied according to duration of employment. High complexity of work appears to be associated with risk of dementia, but effects may vary according to subtype.

    The aim of the study was to explore the effects of domestic employment on the well-being of child domestic workers (CDWs) in India and the Philippines. A questionnaire was administered to 700 CDWs and 700 school-attending controls in the two countries. In India, 36% of CDWs started work before age 12, 48% worked because of poverty or to repay loans, 46% worked >10 h per day, and 31% were physically punished by employers. Filipino CDWs were mainly migrants from rural areas, 47% were working to continue their studies and 87% were attending school, compared with 35% of Indians. In India, 67% of CDWs and 25% of controls scored in the lowest tertile (p<0.001) compared with 36% and 30%, respectively, in the Philippines (p=02). Key significant correlates of low psychosocial scores were non-attendance at school, long working hours, physical punishment, limited support networks and poor health. This study shows that it is not domestic work that is intrinsically harmful, but rather the circumstances and conditions of work, which could be improved through pragmatic regulatory measures.

    of very specific and quantitative predictions were put forward which were aimed at direct experimental tests of the developed concepts [9]. Experimentally, wetting phenomena proved to be a rather difficult field of research. While contact angles seem quite easy to measure, deeper insight can only be gained by assessing the physical properties of minute amounts of material, as provided by the molecularly thin wetting layers. At the same time, the variations in the chemical potential relevant for studying wetting transitions are very small, such that system stability sometimes poses hard to solve practical problems. As a consequence, layering transitions in cryogenic systems were among the first to be thoroughly studied [10] experimentally, since they require comparably moderate stability. First-order wetting transitions were not observed experimentally before the early nineties, either in (cryogenic) quantum systems [11,12] or in binary liquid mixtures [13,14]. The first observation of critical wetting, a continuous wetting transition, in 1996 [15] was a major breakthrough [16]. In the meantime, a detailed seminal paper by Pierre Gilles de Gennes published in 1985 [17] had spurred a large number of new research projects which were directed to wetting phenomena other than those related to phase transitions. More attention was paid to non-equilibrium physics, as it is at work when oil spreads over a surface, or a liquid coating beads off (`dewets') from its support and forms a pattern of many individual droplets. This turned out to be an extremely fruitful field of research, and was more readily complemented by experimental efforts than was the case with wetting transitions. It was encouraging to find effects analogous to layering (as mentioned above) in more common systems such as oil films spreading on a solid support [18,19]. Long standing riddles such as the divergence of dissipation at a moving contact line were now addressed both theoretically and experimentally

  9. The Influence of Practice Standards on Massage Therapists’ Work Experience: A Phenomenological Pilot Study

    2010-01-01

    This original research is framed in phenomenological methodology, based on interviews conducted and interpreted using qualitative research methods. The findings suggest that, because of both direct and indirect factors (such as the nebulous nature of the work, general isolation in work conditions, and physical concerns), massage therapists perform their work with multiple sources of ambiguity that are potentially anxiety-causing. Licensing offers potential relief for this anxiety, but also generates a new set of frustrations and work concerns. The new concerns include the potential that practice will change to adapt to non-relevant standards and the difficulty of defining a body of work that frequently defies a “one size fits all” categorization. This pilot study suggests several areas for further exploration and also demonstrates the generativity of phenomenological methodology for research related to massage therapy. PMID:21589709

    In view of the fact that many reports have been published that emphasize the difficult conditions of the German psychotherapy training, the aim of this study was to investigate psychotherapy trainees´ work stress as well as work-related psychosocial risks and resources. Variables of interest were work-related behaviour and experience patterns (AVEM), effort-reward-imbalance, chronic stress and health-related quality of life. 321 participants completed an online survey. The distribution of work-related behaviour and experience patterns as well as the results regarding work overload and mental health are evidence of psychotherapy trainees' strain. AVEM-risk patterns are associated with effort-reward-imbalance, chronic stress and reduced mental health. These results clearly support claims for a modification of the psychotherapy training in Germany.

    This study investigated the influence of stress appraisal and coping on work engagement levels (Absorption, Vigour, and Dedication) of police recruits. Participants were 387 men, ages 20 to 33 yr. (M = 24.1, SD = 2.4), in their last month of academy training before becoming police officers. Partially in support of predictions, work engagement was associated with Stressor control perceived, but not Stress intensity experienced over a self-selected stressor. Although the three dimensions of work engagement were explained by Stressor control and coping, Absorption was the dimension better explained by these variables. Police recruits reporting higher Absorption, Vigour, and Dedication reported using more Active coping and less Behavioural disengagement. Results showed that stress appraisal and coping are important variables influencing work engagement among police recruits. Findings suggested that future applied interventions fostering work engagement among police recruits should reinforce perceptions of control over a stressor as well as Active coping strategies.

    Recent findings have demonstrated that reintegration for Veterans is often challenging. One difficult aspect of reintegration—transitioning into the civilian workplace—has not been fully explored in the literature. To address this gap and examine work reintegration, this mixed methods study examined the perspectives of Veterans with mental health disorders receiving Department of Veterans Affairs healthcare. Forty Veterans rated factors that affect work success; participants also provided narratives on their most and least successful work experiences. We used t-tests and qualitative analysis to compare participants who did and did not serve in combat. Several themes relevant to work reintegration emerged in the narratives, particularly for Veterans who served in combat. An array of work difficulties were reported in the months following military discharge. In addition, Veterans who served in combat reported significantly more work barriers than Veterans who did not serve in combat, particularly health-related barriers. In conclusion, Veterans with mental health disorders who served in combat experienced more work reintegration difficulty than their counterparts who did not serve in combat. The role of being a Veteran affected how combat Veterans formed their self-concept, which also shaped their work success and community reintegration, especially during the early transition period.

  14. The role of interference control in working memory: a study with children at risk of ADHD.

    PubMed

    2006-12-01

    The study aimed to test whether the impairment in a working memory task observed in children at risk of ADHD was due to a lack of control of interfering information being processed whilst carrying out the memory task. Two groups of children at risk of ADHD with or without a learning disability (reading impairment) were compared to a control group in a working memory task. Activation of irrelevant items was tested with a lexical decision task presented immediately after the final recall in about half of the trials. Results showed a poor working memory performance in children at risk of ADHD and reading disability associated with a larger activation of irrelevant information than that of control children. Results indicated that the to-be-excluded and interfering items are still highly accessible to working memory in children that fail the working memory task. The examination of working memory and interference control of children at risk of ADHD with a learning disability revealed a counterintuitive picture of children with poor working memory showing better recall/activation of processed information. This picture is consistent with a view of working memory related to an efficient inhibitory control that influences cognitive functioning.

    Work performance research highlights that psychometric cognitive measures and cognitive component information processing measures are strong predictors of success in multitasking work environments [14]. People with a mild to moderate traumatic brain injury (TBI) returning to a job requiring multitasking, may have difficulty succeeding despite pre-morbid equivalent cognitive scores. A critical case study is presented to begin to determine what aspects of information processing contribute to difficulties in multitasking work performance, for people with a TBI. The Perceive Recall Plan and Perform (PRPP) System of Task Analysis: Workplace Interview (i.e. PRPP@WORK) is used with the employer to obtain information processing scores. Results indicate substantial information processing deficits were perceived by the employer for the employee with a TBI. Future larger studies of people with a TBI who return to work that requires multitasking are needed to more clearly indicate: the level of multitasking they perform; what aspects of information processing hinder their work performance; the impact on performance of perceived cognitive load by the person with a TBI and the type and impact of support provided to improve their work performance.

    The aim of this study was to determine the effects of transformational leadership and its components on work engagement among hospital nurses. There are a few set of researches that have focused on the effects of transformational leadership on work engagement in nurses. A descriptive, correlational, cross-sectional design was used. In this study, 240 nurses have been chosen by stratified random sampling method which filled related self-reported scales include multifactor leadership questionnaire (MLQ) and work engagement scale. Data analysis has been exerted according to the statistical method of simple and multiple correlation coefficients. Findings indicated that the effect of this type of leadership on work engagement and its facets is positive and significant. In addition, the research illustrates that transformational leaders transfer their enthusiasm and high power to their subordinates by the way of modeling. This manner can increase the power as a component of work engagement in workers. Idealized influence among these leaders can result in forming a specific belief among employees toward those leaders and leaders can easily transmit their inspirational motivation to them. Consequently, it leads to make a positive vision by which, and by setting high standards, challenges the employees and establishes zeal along with optimism for attaining success in works. regarding to the results we will expand leadership and work engagement literature in hospital nurses. Also, we conclude with theoretical and practical implications and propose a clear horizon for future researches.

    Background: It has been proposed that night shift work could increase breast cancer incidence. A 2007 World Health Organization review concluded, mainly from animal evidence, that shift work involving circadian disruption is probably carcinogenic to humans. We therefore aimed to generate prospective epidemiological evidence on night shift work and breast cancer incidence. Methods: Overall, 522 246 Million Women Study, 22 559 EPIC-Oxford, and 251 045 UK Biobank participants answered questions on shift work and were followed for incident cancer. Cox regression yielded multivariable-adjusted breast cancer incidence rate ratios (RRs) and 95% confidence intervals (CIs) for night shift work vs no night shift work, and likelihood ratio tests for interaction were used to assess heterogeneity. Our meta-analyses combined these and relative risks from the seven previously published prospective studies (1.4 million women in total), using inverse-variance weighted averages of the study-specific log RRs. Results: In the Million Women Study, EPIC-Oxford, and UK Biobank, respectively, 673, 28, and 67 women who reported night shift work developed breast cancer, and the RRs for any vs no night shift work were 1.00 (95% CI = 0.92 to 1.08), 1.07 (95% CI = 0.71 to 1.62), and 0.78 (95% CI = 0.61 to 1.00). In the Million Women Study, the RR for 20 or more years of night shift work was 1.00 (95% CI = 0.81 to 1.23), with no statistically significant heterogeneity by sleep patterns or breast cancer risk factors. Our meta-analysis of all 10 prospective studies included 4660 breast cancers in women reporting night shift work; compared with other women, the combined relative risks were 0.99 (95% CI = 0.95 to 1.03) for any night shift work, 1.01 (95% CI = 0.93 to 1.10) for 20 or more years of night shift work, and 1.00 (95% CI = 0.87 to 1.14) for 30 or more years. Conclusions: The totality of the prospective evidence shows that night shift work, including long

    Certified nursing assistants (CNAs) are the principal bedside caregivers in nursing homes, yet little is known about their perceptions of the work environment. This population-based, cross-sectional study used a mailed questionnaire to a random sample of Iowa CNAs (N = 584), representing 166 nursing homes. Of the respondents, 88.5% (n = 517) were currently employed in long-term care settings; however, 11.5% (n = 67) indicated they had left their jobs. When CNA responses were compared with those of other occupational groups, general workers reported higher scores on involvement, coworker cohesion, work pressure, and supervisor support. Those who left their CNA jobs rated their work environment as characteristic of excessive managerial control and task orientation. Results of this study emphasize the importance of the relationship between CNAs and their supervisors, CNAs’ need for greater autonomy and innovation, and the need for the work environment to change dramatically in the area of human resource management.

    In past years, research and corporate scandals have evidenced the destructive effects of the dark triad at work, consisting of narcissism (extreme self-centeredness), psychopathy (lack of empathy and remorse) and Machiavellianism (a sense of duplicity and manipulativeness). The dark triad dimensions have typically been conceptualized as stable personality traits, ignoring the accumulating evidence that momentary personality expressions – personality states – may change due to the characteristics of the situation. The present research protocol describes a qualitative study that aims to identify triggers of dark triad states at work by following a grounded theory approach using semi-structured interviews. By building a comprehensive categorization of dark triad triggers at work scholars may study these triggers in a parsimonious and structured way and organizations may derive more effective interventions to buffer or prevent the detrimental effects of dark personality at work.

    With the rapid development of the child welfare system in China over recent years, medical social work has been increasingly involved in providing child protection services in several hospitals in Shanghai. Focusing on five cases in this paper, the exploratory study aims to present a critical overview of current practices and effects of medical social work for child protection, based on a critical analysis of the multidimensional role of social work practitioners engaged in the provision of child protection services as well as potential challenges. Implications and suggestions for future improvements of China's child protection system are also discussed.
