    In China, the prevalence of hypertension is increasing and is showing an epidemic accelerating trend. However, there is a lack of studies reporting the hypertension status of rural residents with minimum living allowances. We performed a cross-sectional study including 11,435 (5285 men and 6150 women) from the general population aged ≥35 years in the Liaoning Province of China from 2012 to 2013, of which 1258 (11.0%) participants came from minimal assurance families. Anthropometric measurements, laboratory examinations and self-reported lifestyle factor information were collected by trained personnel. Multivariate logistic regression was used to detect the association between socioeconomic status (SES) and the risk of hypertension. We found that the prevalence of hypertension was as high as 61.9% in participants from minimal assurance families and the odd ratio for hypertension was 1.32 (95% CI: 1.15-1.52). The awareness, treatment, and control rates among treated hypertensive participants did not increase with higher level of income and education. In the total sample, the lower income levels increased the risk for hypertension, but education didn't show a significant association with hypertension. Thus, there is a severe hypertension situation in the Liaoning rural population of minimal assurance families, which need more attention and prevention and control measures for hypertension.

    Low-risk limits recommended for alcohol consumption vary substantially across different national guidelines. To define thresholds associated with lowest risk for all-cause mortality and cardiovascular disease, we studied individual-participant data from 599 912 current drinkers without previous cardiovascular disease. We did a combined analysis of individual-participant data from three large-scale data sources in 19 high-income countries (the Emerging Risk Factors Collaboration, EPIC-CVD, and the UK Biobank). We characterised dose-response associations and calculated hazard ratios (HRs) per 100 g per week of alcohol (12·5 units per week) across 83 prospective studies, adjusting at least for study or centre, age, sex, smoking, and diabetes. To be eligible for the analysis, participants had to have information recorded about their alcohol consumption amount and status (ie, non-drinker vs current drinker), plus age, sex, history of diabetes and smoking status, at least 1 year of follow-up after baseline, and no baseline history of cardiovascular disease. The main analyses focused on current drinkers, whose baseline alcohol consumption was categorised into eight predefined groups according to the amount in grams consumed per week. We assessed alcohol consumption in relation to all-cause mortality, total cardiovascular disease, and several cardiovascular disease subtypes. We corrected HRs for estimated long-term variability in alcohol consumption using 152 640 serial alcohol assessments obtained some years apart (median interval 5·6 years [5th-95th percentile 1·04-13·5]) from 71 011 participants from 37 studies. In the 599 912 current drinkers included in the analysis, we recorded 40 310 deaths and 39 018 incident cardiovascular disease events during 5·4 million person-years of follow-up. For all-cause mortality, we recorded a positive and curvilinear association with the level of alcohol consumption, with the minimum mortality risk around or below 100

    Full Text Available Participation banks collect participation funds for credit allocation by participation accounts and special current accounts as main function. Profit or loss offered to participation accounts on base of participation share ratio while special current accounts are considered as cost-free resources. Participation funds are used in the models that analyze participation banks’ performance. Although participation fund types are not considered as variables also special current accounts. This research brings suggestions for the variables for performance analysis of participation banks for further researches.

  11. Are Participants Aware of the Type and Intensity of Transcranial Direct Current Stimulation?

    Directory of Open Access Journals (Sweden)

    Matthew F Tang

    Full Text Available Transcranial direct current stimulation (tDCS is commonly used to alter cortical excitability but no experimental study has yet determined whether human participants are able to distinguish between the different types (anodal, cathodal, and sham of stimulation. If they can then they are not blind to experimental conditions. We determined whether participants could identify different types of stimulation (anodal, cathodal, and sham and current strengths after experiencing the sensations of stimulation during current onset and offset (which are associated with the most intense sensations in Experiment 1 and also with a prolonged period of stimulation in Experiment 2. We first familiarized participants with anodal, cathodal, and sham stimulation at both 1 and 2 mA over either primary motor or visual cortex while their sensitivity to small changes in visual stimuli was assessed. The different stimulation types were then applied for a short (Experiment 1 or extended (Experiment 2 period with participants indicating the type and strength of the stimulation on the basis of the evoked sensations. Participants were able to identify the intensity of stimulation with shorter, but not longer periods, of stimulation at better than chance levels but identification of the different stimulation types was at chance levels. This result suggests that even after exposing participants to stimulation, and ensuring they are fully aware of the existence of a sham condition, they are unable to identify the type of stimulation from transient changes in stimulation intensity or from more prolonged stimulation. Thus participants are able to identify intensity of stimulation but not the type of stimulation.

    A detailed experimental study is presented of the bootstrap and Pfirsch-Schlueter currents that are predicted by neoclassical transport theory. In a toroidal octupole, on magnetic surfaces within the separatrix, the observed parallel plasma currents are in excellent quantitative agreement with neoclassical theory with regard to the spatial structure (along a magnetic surface), collisionality dependence and toroidal magnetic field dependence. On magnetic surfaces outside the separatrix, the ion portion of the parallel current is in agreement with neoclassical theory but the electron parallel current is observed to obtain a unidirectional component which deviates from and exceeds the theoretical prediction

    Full Text Available Loss to follow-up can introduce bias into research, making it difficult to develop inclusive evidence-based health policies and practice guidelines. We aimed to deepen understanding of reasons why participants leave or remain in longitudinal health studies. We interviewed 59 researchers and current and former research participants in six focus groups (n = 55 or interviews (n = 4 at three study centers in a large academic research institution. We used minimally structured interview guides and inductive thematic analysis to explore participant-level, study-level, and contextual participation barriers and facilitators. Four main themes emerged: transportation, incentives and motivation, caregiver concerns, and the social and physical environment. Themes shared crosscutting issues involving funding, flexibility, and relationships between researchers and research participants. Study-level and contextual factors appear to interact with participant characteristics, particularly socioeconomic status and disease severity to affect participant retention. Participants’ characteristics do not seem to be the main cause of study dropout. Researchers and funders might be able to address contextual and study factors in ways that reduce barriers to participation.

    This qualitative study explored the concept of acceptance of wholegrain foods in an adult population in the UK. Data was generated via focus groups with volunteers from a randomised controlled wholegrain based dietary intervention study (the WHOLEheart study). WHOLEheart volunteers, who did not habitually eat wholegrain foods, were randomised to one of three experimental regimes: (1) incorporating 60 g/day whole grains into the diet for 16 weeks; (2) incorporating 60 g/day whole grains into the diet for 8 weeks, doubling to 120 g/day for the following 8 weeks; (3) a control group. Focus groups to examine factors relating to whole grain acceptability were held one month post-intervention. For participants incorporating whole grains into their diet, acceptance was dependent upon: (a) 'trial acceptance', relating to the taste, preparation and perceived impact of the wholegrain foods on wellbeing, and (b) 'dietary acceptance' which involved the compatibility and substitutability of whole grains with existing ingredients and meal patterns. Barriers to sustained intake included family taste preferences, cooking skills, price and availability of wholegrain foods. Although LDL lowering benefits of eating whole grains provided the impetus for the WHOLEheart study, participants' self-reported benefits of eating wholegrain foods included perceived naturalness, high fibre content, superior taste, improved satiety and increased energy levels provided a stronger rationale for eating whole grains.

    Characteristics of a 40-kV, 750-kA, multichannel rail gap are presented. The gap is a three electrode, field-distortion-triggered design, with a total switch inductance of less than 10 nH. At maximum ratings, the gap typically switches 10 C per shot, at 700 kA, with a jitter of less than 2 ns. Image-converter streak photographs were used to study channel evolution and current division. Transient gas-pressure measurements were made to investigate the arc generated shocks and to detect single channel failure. Channel current sharing and simultaneity are described and their effects on the switch inductance and lifetime are discussed. Lifetime tests of the rail gap were performed. Degradation in the channel current-sharing and erosion measurements are discussed.

Research ethics committees (RECs) have a centrally important role in guiding this practice, but standardisation of the ethical approval process in Ireland is lacking. Our aim was to examine REC policies, experiences and concerns with respect to the payment of participants in research projects in Ireland. Postal survey of all RECs in Ireland. Response rate was 62.5% (n=50). 80% of RECs reported not to have any established policy on the payment of research subjects while 20% had refused ethics approval to studies because the investigators proposed to pay research participants. The most commonly cited concerns were the potential for inducement and undermining of voluntary consent. There is considerable variability among RECs on the payment of research participants and a lack of clear consensus guidelines on the subject. The development of standardised guidelines on the payment of research subjects may enhance recruitment of research participants.

    A second epidemiological analysis of mortality and cancer incidence in UK participants in the UK atmospheric nuclear tests and associated experimental programmes has provided broadly reassuring results. Overall death rates in test participants are lower than those in the general population and similar to those in a closely matched control group. Observations in the extended period of follow-up suggest that the excess of multiple myeloma seen in the first analysis was a chance finding. The extended follow-up does not provide any new evidence to support the finding of apparent excess of leukaemia found in the first analysis. However, the possibility that test participation may have caused a small risk of leukaemia in the early years after the tests cannot be ruled out. (author)

    To find out to what extent nurses were perceived to be participating in audit, to identify factors thought to impede their involvement, and to assess progress towards multidisciplinary audit. Qualitative. Focus groups and interviews. Chairs of audit groups and audit support staff in hospital, community and primary health care and audit leads in health authorities in the North West Region. In total 99 audit leads/support staff in the region participated representing 89% of the primary health care audit groups, 80% of acute hospitals, 73% of community health services, and 59% of purchasers. Many audit groups remain medically dominated despite recent changes to their structure and organisation. The quality of interprofessional relations, the leadership style of the audit chair, and nurses' level of seniority, audit knowledge, and experience influenced whether groups reflected a multidisciplinary, rather than a doctor centred approach. Nurses were perceived to be enthusiastic supporters of audit, although their active participation in the process was considered substantially less than for doctors in acute and community health services. Practice nurses were increasingly being seen as the local audit enthusiasts in primary health care. Reported obstacles to nurses' participation in audit included hierarchical nurse and doctor relationships, lack of commitment from senior doctors and managers, poor organisational links between departments of quality and audit, work load pressures and lack of protected time, availability of practical support, and lack of knowledge and skills. Progress towards multidisciplinary audit was highly variable. The undisciplinary approach to audit was still common, particularly in acute services. Multidisciplinary audit was more successfully established in areas already predisposed towards teamworking or where nurses had high involvement in decision making. Audit support staff were viewed as having a key role in helping teams to adopt a

  3. Participation in Social Media: Studying Explicit and Implicit Forms of Participation in Communicative Social Networks

    2016-10-01

    Full Text Available The diverse forms of participation in social media raise many methodological and ethical issues that should be acknowledged in research. In this paper, participation in social media is studied by utilising the framework of explicit and implicit participation. The focus is on the communicative and communal aspects of social media. The aim of the paper is to promote the reconsideration of what constitutes participation when online users create connections rather than content. The underlying argument is that research on social media and the development of methods should concentrate more on implicit forms of participation.

    Technology has transformed our lifestyles in dramatic and significant ways, including new and less expensive options for recruiting study participants. This study examines cost and participant differences between two recruitment sources, Craigslist (CL), and print newspapers (PNs). This paper also reviewed and compared studies involving clinical trials published since 2010 that recruited participants using CL alone or in combination with other methods. Secondary data analyses from a parent study involving a randomized controlled trial of a mail-based intervention to promote self-change with problem drinkers. Significant differences were found between CL and PN participants on most demographic and pretreatment drinking variables. While all participants had AUDIT scores suggestive of an alcohol problem and reported drinking at high-risk levels, CL participants had less severe drinking problem histories, were considerably younger, and had a higher socioeconomic status than PN participants. The total advertising costs for the 65 CL ads ($275) were significantly less than the 69 PN ads ($33, 311). The recruiting cost per eligible participant was vastly less expensive using CL ($1.46) compared to print newspaper ads ($116.88). Using CL is a viable recruitment method for soliciting participants, particularly those that are younger, for alcohol intervention studies. It is also less expensive than newspaper ads. When CL participants were recruited, they reported being slightly more confident to change their drinking than PN participants. Limitations of using CL are discussed, including that some initial ad responders gave inconsistent answers to similar questions and a few tried to enter the study more than once.

    To understand adolescents' and parents' willingness to participate (WTP) in a hypothetical phase I prevention study of sexually transmitted infections, discordance within adolescent-parent dyads, and expectations of each other during decision-making. Adolescent-parent dyads were recruited to participate in a longitudinal study about research participation attitudes. Adolescents (14-17 years old) and their parents (n = 301 dyads) participated. None. Individual interviews at baseline assessed WTP on a 6-level Likert scale. WTP was dichotomized (willing/unwilling) to assess discordance. WTP was reported by 60% (182 of 301) of adolescents and 52% (156 of 300) of parents. In bivariate analyses, older adolescent age, sexual experience, and less involvement of parents in research processes were associated with higher level of WTP for adolescents; only sexual experience remained in the multivariable analysis. For parents, older adolescent age, perceived adolescent sexual experience, and conversations about sexual health were significant; only conversations remained. Dyadic discordance (44%, 132 of 300) was more likely in dyads in which the parent reported previous research experience, and less likely when parents reported higher family expressiveness. Adolescents (83%, 248 of 299) and parents (88%, 263 of 300) thought that the other would have similar views, influence their decision (adolescents 66%, 199 of 300; parents 75%, 224 of 300), and listen (adolescents 90%, 270 of 300; parents 96%, 287 of 300). There were no relationships between these perceptions and discordance. Inclusion of adolescents in phase I clinical trials is necessary to ensure that new methods are safe, effective, and acceptable for them. Because these trials currently require parental consent, strategies that manage adolescent-parent discordance and support adolescent independence and parental guidance are critically needed.

    Prader-Willi syndrome (PWS) is a neurodevelopmental genetic disorder characterized by intellectual disabilities and insatiable appetite with compulsive eating leading to severe obesity with detrimental health consequences. Transcranial direct current stimulation (tDCS) has been shown to modulate decision-making and cue-induced food craving in healthy adults. We conducted a pilot double blind, sham-controlled, multicenter study of tDCS modulation of food drive and craving in 10 adult PWS participants, 11 adult obese (OB) and 11 adult healthy-weight control (HWC) subjects. PWS and OB subjects received five consecutive daily sessions of active or sham tDCS over the right dorsolateral prefrontal cortex (DLPFC), while HWC received a single sham and active tDCS in a crossover design. Standardized psychometric instruments assessed food craving, drive and hyperphagia by self-report and caregiver assessment over 30 days. Robust baseline differences were observed in severity scores for the Three-Factor Eating Questionnaire (TFEQ) and Dykens Hyperphagia Questionnaire (DHQ) for PWS compared to HWC while obese participants were more similar to HWC. Active tDCS stimulation in PWS was associated with a significant change from baseline in TFEQ Disinhibition (Factor II) (Ƶ = 1.9, P food drive and behaviors impacting hyperphagia in PWS.

    After two surveys for indoor air pollutants (radon and other chemicals) the homeowners were surveyed for their reactions. The results of these participant evaluation surveys, assuming that the participants that responded to the survey were representative, indicate that homeowners will accept a significant level of monitoring activity as part of an indoor air quality field study. Those participants completing surveys overwhelmingly enjoyed being in the studies and would do it again. We believe that the emphasis placed on positive homeowner interactions and efforts made to inform participants throughout our studies were positive factors in this result. There was no substantial differences noted in the responses between the 70-house study, which included a homeowner compensation payment of $100, and the 300-house study, which did not include a compensation payment. These results provide encouragement to conduct future complex, multipollutant indoor air quality studies when they are scientifically sound and cost effective

    Public participation has received increasing attention in environmental policy making world wide. Yet research has been inadequate to answer fundamental questions about how successful past programs have been, what factors lead to success, and where efforts to improve public involvement should focus. To address these questions, we examine the case study record of public participation efforts in the United States over the last 30 years. We evaluate the success of numerous examples of public participation in environmental decision making and identify the factors that lead to success. The paper deals with a number of themes, including: The extent to which participation can incorporate public values into decision making, improve the substantive quality of decisions, reduce conflict, increase trust in institutions, and educate and inform the public; What can be expected from different approaches to public participation, such as public meetings, advisory committees, and mediation; The relative importance of the participatory process vs. the context in which participation takes place; Procedural features of particular importance; and The relationship between participation and implementation. The paper provides general results that can be used to guide the improvement of public participation programs, support assessment of innovative methods, and advance the theoretical understanding of public participation.

    Recruitment of minority participants for clinical research studies has been the topic of several analytical works. Yet retention of participants, most notably minority and underserved populations, is less reported and understood, even though these populations have elevated health risks. This article describes two related, intervention-based formative research projects in which researchers used treatment theory to address issues of recruitment and retention of minority women participants in an exercise program to reduce obesity. Treatment theory incorporates a model of health promotion that allows investigators to identify and control sources of extraneous variables. The authors' research demonstrates that treatment theory can improve retention of minority women participants by considering critical inputs, mediating processes, and substantive participant characteristics in intervention design.

    Full Text Available Objective: To examine the representativeness of participants attending a lifestyle intervention study addressing obese pregnant women. Methods: Retrospective comparison of baseline data, attendance to oral glucose tolerance test (OGTT during pregnancy, and pregnancy outcome in eligible women stratified according to study participation. Of 750 eligible women with a self-reported BMI > 30 kg/m2, and a live singleton pregnancy, 510 were eligible for inclusion and 425 were randomized to either active intervention (n= 284 or to standard obstetric care (n= 141 including two standard OGTT. The 85 women who declined participation or were excluded due to competing diseases and 240 women who did not respond to the initial invitation received the same standard care. Results: The randomized women had similar BMI but a lower parity and age, and were more frequently non-smokers, born in Denmark and married or cohabitating with their partner than the non-participants. Women participating in the trial had a higher compliance to the second OGTT compared to non-participants, also after correcting for age and nationality. There was no difference in pregnancy outcome, i.e., fetal weight and length, gestational age as well as mode of delivery. Conclusion: Women declining participation in a randomized lifestyle intervention study in pregnancy have characteristics indicating they are those who might benefit the most from lifestyle intervention.

    Background When conducting qualitative research, participants usually share lots of personal and private information with the researcher. As researchers, we must preserve participants' identity and confidentiality of the data. Objective To critically analyze an ethical conflict encountered regarding confidentiality when doing qualitative research. Research design Case study. Findings and discussion one of the participants in a study aiming to explain the meaning of living with HIV verbalized his imminent intention to commit suicide because of stigma of other social problems arising from living with HIV. Given the life-threatening situation, the commitment related to not disclosing the participant's identity and/or the content of the interview had to be broken. To avoid or prevent suicide, the therapist in charge of the case was properly informed about the participant's intentions. One important question arises from this case: was it ethically appropriate to break the confidentiality commitment? Conclusion confidentiality could be broken if a life-threatening event is identified during data collection and participants must know that. This has to be clearly stated in the informed consent form.

    Full Text Available OBJECTIVE: Diabetes mellitus is highly prevalent and can lead to serious complications and mortality. Patient education can help to avoid negative outcomes, but up to half of the patients do not participate. The aim of this study was to analyze patients' attitudes towards diabetes education in order to identify barriers to participation and develop strategies for better patient education. METHODS: We conducted a qualitative study. Seven GP practices were purposively selected based on socio-demographic data of city districts in Hamburg, Germany. Study participants were selected by their GPs in order to increase participation. Semi-structured face-to-face interviews were conducted with 14 patients. Interviews were audiotaped and transcribed verbatim. The sample size was determined by data saturation. Data were analysed by qualitative content analysis. Categories were determined deductively and inductively. RESULTS: The interviews yielded four types of barriers: 1 Statements and behaviour of the attending physician influence the patients' decisions about diabetes education. 2 Both, a good state of health related to diabetes and physical/psychosocial comorbidity can be reasons for non-participation. 3 Manifold motivational factors were discussed. They ranged from giving low priority to diabetes to avoidance of implications of diabetes education as being confronted with illness narratives of others. 4 Barriers also include aspects of the patients' knowledge and activity. CONCLUSIONS: First, physicians should encourage patients to participate in diabetes education and argue that they can profit even if actual treatment and examination results are promising. Second, patients with other priorities, psychic comorbidity or functional limitations might profit more from continuous individualized education adapted to their specific situation instead of group education. Third, it might be justified that patients do not participate in diabetes education if

  4. Using data mining techniques to characterize participation in observational studies.

    Linden, Ariel; Yarnold, Paul R

    2016-12-01

    Data mining techniques are gaining in popularity among health researchers for an array of purposes, such as improving diagnostic accuracy, identifying high-risk patients and extracting concepts from unstructured data. In this paper, we describe how these techniques can be applied to another area in the health research domain: identifying characteristics of individuals who do and do not choose to participate in observational studies. In contrast to randomized studies where individuals have no control over their treatment assignment, participants in observational studies self-select into the treatment arm and therefore have the potential to differ in their characteristics from those who elect not to participate. These differences may explain part, or all, of the difference in the observed outcome, making it crucial to assess whether there is differential participation based on observed characteristics. As compared to traditional approaches to this assessment, data mining offers a more precise understanding of these differences. To describe and illustrate the application of data mining in this domain, we use data from a primary care-based medical home pilot programme and compare the performance of commonly used classification approaches - logistic regression, support vector machines, random forests and classification tree analysis (CTA) - in correctly classifying participants and non-participants. We find that CTA is substantially more accurate than the other models. Moreover, unlike the other models, CTA offers transparency in its computational approach, ease of interpretation via the decision rules produced and provides statistical results familiar to health researchers. Beyond their application to research, data mining techniques could help administrators to identify new candidates for participation who may most benefit from the intervention. © 2016 John Wiley & Sons, Ltd.

    Background Participation in a sports group is key for the prevention of incident functional disability. Little is known about the correlates of older adults’ participation in sports groups, although this could assist with the development of effective health strategies. The purpose of this study was to identify the demographic and biological, psychosocial, behavioral, social and cultural, and environmental correlates of sports group participation among Japanese older adults. Methods Data were obtained from the Japan Gerontological Evaluation study, which was a population–based cohort of people aged ≥65 years without disability enrolled from 31 municipalities across Japan (n = 78,002). Poisson regression analysis was used to determine the associations between the factors and participation in sports groups. Results Non-regular participation in sports groups was associated with lower educational level, being employed, and working the longest in the agricultural/forestry/fishery industry among the demographic and biological factors and poor self-rated health and depression among the psychosocial factors. Of the behavioral factors, current smoking was negatively associated and current drinking was positively associated with regular participation in sports groups. Among the social and cultural factors, having emotional social support and participating in hobby clubs, senior citizen clubs, or volunteer groups were associated with a high prevalence of participation in sports groups. Perceptions of the presence of parks or sidewalks, good access to shops, and good accessibility to facilities were positively associated with participation in sports groups among the environmental factors. Conclusions Our study suggests that the promotion of activities that could increase older adults’ participation in sports groups should consider a broad range of demographic and biological, psychosocial, behavioral, social and cultural, and environmental factors.

    Full Text Available Participation in a sports group is key for the prevention of incident functional disability. Little is known about the correlates of older adults' participation in sports groups, although this could assist with the development of effective health strategies. The purpose of this study was to identify the demographic and biological, psychosocial, behavioral, social and cultural, and environmental correlates of sports group participation among Japanese older adults.Data were obtained from the Japan Gerontological Evaluation study, which was a population-based cohort of people aged ≥65 years without disability enrolled from 31 municipalities across Japan (n = 78,002. Poisson regression analysis was used to determine the associations between the factors and participation in sports groups.Non-regular participation in sports groups was associated with lower educational level, being employed, and working the longest in the agricultural/forestry/fishery industry among the demographic and biological factors and poor self-rated health and depression among the psychosocial factors.

    Purpose: To report current technology implementation, radiation therapy physics and treatment planning practices, and results of treatment planning exercises among 261 institutions belonging to the Children's Oncology Group (COG). Methods and Materials: The Radiation Therapy Committee of the newly formed COG mandated that each institution demonstrate basic physics and treatment planning abilities by satisfactorily completing a questionnaire and four treatment planning exercises designed by the Quality Assurance Review Center. The planning cases are (1) a maxillary sinus target volume (for two-dimensional planning), (2) a Hodgkin's disease mantle field (for irregular-field and off-axis dose calculations), (3) a central axis blocked case, and (4) a craniospinal irradiation case. The questionnaire and treatment plans were submitted (as of 1/30/02) by 243 institutions and completed satisfactorily by 233. Data from this questionnaire and analyses of the treatment plans with monitor unit calculations are presented. Results: Of the 243 clinics responding, 54% use multileaf collimators routinely, 94% use asymmetric jaws routinely, and 13% use dynamic wedges. Nearly all institutions calibrate their linear accelerators following American Association of Physicists in Medicine protocols, currently 16% with TG-51 and 81% with TG-21 protocol. Treatment planning systems are relied on very heavily for all calculations, including monitor units. Techniques and results of each of the treatment planning exercises are presented. Conclusions: Together, these data provide a unique compilation of current (2001) radiation therapy practices in institutions treating pediatric patients. Overall, the COG facilities have the equipment and the personnel to perform high-quality radiation therapy. With ongoing quality assurance review, radiation therapy compliance with COG protocols should be high

    To offer a unique contribution to the evolving debate around the use of the telephone during semistructured interview by drawing on interviewees' reflections on telephone interview during a grounded theory study. The accepted norm for qualitative interviews is to conduct them face-to-face. It is typical to consider collecting qualitative data via telephone only when face-to-face interview is not possible. During a grounded theory study, exploring users' experiences with overnight mask ventilation for sleep apnoea, the authors selected the telephone to conduct interviews. This article reports participants' views on semistructured interview by telephone. An inductive thematic analysis was conducted on data pertaining to the use of the telephone interview in a grounded theory study. The data were collected during 4 months of 2011 and 6 months in 2014. The article presents an inductive thematic analysis of sixteen participants' opinions about telephone interviewing and discusses these in relation to existing literature reporting the use of telephone interviews in grounded theory studies. Overall, participants reported a positive experience of telephone interviewing. From each participants reports we identified four themes from the data: being 'phone savvy; concentrating on voice instead of your face; easy rapport; and not being judged or feeling inhibited. By drawing on these data, we argue that the telephone as a data collection tool in grounded theory research and other qualitative methodologies need not be relegated to second best status. Rather, researchers can consider telephone interview a valuable first choice option. © 2015 John Wiley & Sons Ltd.

    A pilot study is currently being carried out by ENIQ (European Network for Inspection Qualification) in order to explore the issues involved in inspection qualification applied along the general principles of the European methodology. The components selected for the pilot study are austenitic pipe to pipe and pipe to elbows welds typical of those in BWR recirculation loops. A range of defect parameters has been defined. A suitable inspection procedure designed to find the designated defects will be applied to geometrically representative test pieces. The procedure/equipment will be qualified through open trials and technical justification. The personnel qualification will be done in a blind way. Once all features of the inspection system will have been qualified an in-service inspection will be simulated in order to test the feasibility of the qualification approach followed. In this paper the current status of this pilot study is discussed. (orig.)

    Full Text Available The increase in per capita income and rapid urbanization, have contributed significantly to changes in consumption behaviour leading to increased waste generation.  Waste disposed to landfill sites is fast becoming unfeasible thus requiring a more effective management of waste material involving waste reduction, reuse and recycling. The success of recycling program, however, is largely dependent on household participation activities which are essentially behaviour driven. The recycling performance of Malaysian households is still low as it stands at 5.5% compared to Singapore and Vietnam which are 56% and 22% respectively. This study examines recycling behaviour among households and the influence of socioeconomic, demographic and behavioural characteristics on households’ participation in recycling program in Malaysia.  A sample of 300 randomly selected household were surveyed.  The findings revealed that most of the households (70% claim that they are practicing recycling particularly types of paper and old clothes. The factors of participation in recycling show equal results both for environmental concerns and economic benefits. Those who did not participate in recycling, listed household issues or behaviour, namely lack of time and materials to recycle, inconvenient, lack of space, lack of facilities and information as well as laziness, as barriers. The paper finally highlights the factors which can encourage household to be involved in recycling and give recommendations to the authorities in terms of facilities and infrastructures to facilitate the program.

    Informed consent in research is partly achieved through the use of information sheets. There is a perception however that these information sheets are long and complex. The recommended reading level for patient information is grade 6, or 11-12 years old. To investigate whether the readability of participant information sheets has changed over time, whether particular study characteristics are related to poorer readability and whether readability and other study characteristics are related to successful study recruitment. Method: We obtained 522 information sheets from the UK National Institute for Health Research Clinical Research Network: Mental Health portfolio database and study principal investigators. Readability was assessed with the Flesch reading index and the Grade level test. Information sheets increased in length over the study period. The mean grade level across all information sheets was 9.8, or 15-16 years old. A high level of patient involvement was associated with more recruitment success and studies involving pharmaceutical or device interventions were the least successful. The complexity of information sheets had little bearing on successful recruitment. Information sheets are far more complex than the recommended reading level of grade 6 for patient information. The disparity may be exacerbated by an increasing focus on legal content. Researchers would benefit from clear guidance from ethics committees on writing succinctly and accessibly and how to balance the competing legal issues with the ability of participants to understand what a study entails. © The Royal College of Psychiatrists 2016.

    Full Text Available Qualitative methodology is used in social and intervention research because it facilitates a deeper analysis of causal factors and development of alternative solutions to social problems. Based on the findings of three studies in the field of political and gender psychology, this article focuses on Participant Action Research (PAR as a useful qualitative approach to deal with social phenomena, such as racism, violence against women, and the problem of children and youth who have been dislocated as the result of armed conflict and sheltered by the Colombian government's program for persons relocated to civil society. This article is composed of three parts. The first part offers historical and theoretical background to the Action Research (AR paradigm, its validation criteria and their meaning for the development of the Latin American rendering of Participant Action Research (PAR.

    Obtaining effective informed consent from research participants is a prerequisite to the conduct of an ethically sound research. Yet it is believed that obtaining quality informed consent is generally difficult in settings with low socioeconomic status. This is so because of the alleged undue inducements and therapeutic misconception among participants. However, there is a dearth of data on factors that motivate research participants to take part in research. Hence, this study was aimed at filling this gap in the Malawian context. We conducted 18 focus group discussions with community members in urban and rural communities of Blantyre in Malawi. Most participants reported that they accepted the invitation to participate in research because of better quality treatment during study also known as ancillary care, monetary and material incentives given to participants, and thorough medical diagnosis. © The Author(s) 2014.

    An ethnographic study in a 10th grade remedial class was undertaken in order to discern patterns of school bullying. Twenty 10th graders were observed over the course of one academic year as they interacted with their peers and teachers. The observations helped us identify dispositional and situational factors which influenced participant roles. In-depth interviews of students involved in school bullying showed how participants interpreted and explained their classroom behaviors. The analysis of the data gathered allowed the identification of four main actor roles recognized in the existing literature on bullying-the pure victim, the pure bully, the provocative-victim, and the bystander-as well as the differentiation between aggressive bullies and the bully managers. Most roles fluctuated according to specific circumstances and often appeared to be moderated by the teacher's management style and contextual variables. Some pupils assumed different roles in different contexts, sometimes changing roles within or between episodes. Teacher personality and style also had an impact on the frequencies and types of aggression and victimization. The use of an ethnographic research paradigm is discussed as an important supplement to positivistic studies of school bullying. © 2014 Wiley Periodicals, Inc.

    After the success of genome-wide association studies to uncover complex trait loci, attempts to explain the remaining genetic heritability (h 2 ) are mainly focused on unraveling rare variant associations and gene-gene or gene-environment interactions. Little attention is paid to the possibility that h 2 estimates are inflated as a consequence of the epidemiological study design. We studied the time series of 54 biochemical traits in 4373 individuals from the Cooperative Health Research In South Tyrol (CHRIS) study, a pedigree-based study enrolling ten participants/day over several years, with close relatives preferentially invited within the same day. We observed distributional changes of measured traits over time. We hypothesized that the combination of such changes with the pedigree structure might generate a shared-environment component with consequent h 2 inflation. We performed variance components (VC) h 2 estimation for all traits after accounting for the enrollment period in a linear mixed model (two-stage approach). Accounting for the enrollment period caused a median h 2 reduction of 4%. For 9 traits, the reduction was of >20%. Results were confirmed by a Bayesian Markov chain Monte Carlo analysis with all VCs included at the same time (one-stage approach). The electrolytes were the traits most affected by the enrollment period. The h 2 inflation was independent of the h 2 magnitude, laboratory protocol changes, and length of the enrollment period. The enrollment process may induce shared-environment effects even under very stringent and standardized operating procedures, causing h 2 inflation. Including the day of participation as a random effect is a sensitive way to avoid overestimation.

    To describe the clinical encounters that occur when a palliative care team provides patient care and the features that influence these encounters and indicate whether they are favorable or unfavorable depending on the expectations and feelings of the various participants. A qualitative case study conducted via participant observation. A total of 12 observations of the meetings of palliative care teams with patients and families in different settings (home, hospital and consultation room) were performed. The visits were follow-up or first visits, either scheduled or on demand. Content analysis of the observation was performed. The analysis showed the normal follow-up activity of the palliative care unit that was focused on controlling symptoms, sharing information and providing advice on therapeutic regimens and care. The environment appeared to condition the patients' expressions and the type of patient relationship. Favorable clinical encounter conditions included kindness and gratitude. Unfavorable conditions were deterioration caused by approaching death, unrealistic family objectives and limited resources. Home visits from basic palliative care teams play an important role in patient and family well-being. The visits seem to focus on controlling symptoms and are conditioned by available resources.

    Longitudinal biomedical research projects study patients or participants over a course of time. No IT solution is known that can manage study participants, enhance quality of data, support re-contacting of participants, plan study visits, and keep track of informed consent procedures and recruitments that may be subject to change over time. In business settings management of personal is one of the major aspects of customer relationship management systems (CRMS). To evaluate whether CRMS are suitable IT solutions for study participant management in biomedical research. Three boards of experts in the field of biomedical research were consulted to get an insight into recent IT developments regarding study participant management systems (SPMS). Subsequently, a requirements analysis was performed with stakeholders of a major biomedical research project. The successive suitability evaluation was based on the comparison of the identified requirements with the features of six CRMS. Independently of each other, the interviewed expert boards confirmed that there is no generic IT solution for the management of participants. Sixty-four requirements were identified and prioritized in a requirements analysis. The best CRMS was able to fulfill forty-two of these requirements. The non-fulfilled requirements demand an adaption of the CRMS, consuming time and resources, reducing the update compatibility, the system's suitability, and the security of the CRMS. A specific solution for the SPMS is favored instead of a generic and commercially-oriented CRMS. Therefore, the development of a small and specific SPMS solution was commenced and is currently on the way to completion.

    This article describes the whole picture of Japan HOspice and Palliative Care Evaluation Study 3 (J-HOPE3 Study) including study design and demographic data. The aims of the J-HOPE3 study were to (1) evaluate the process, structure, and outcome of palliative care in the following care settings: acute hospitals, inpatient hospice/palliative care units (PCUs), and home hospice services; (2) examine bereaved family members' self-reported psychosocial conditions, such as grief and depression, as bereavement outcomes; (3) provide data to ensure and improve the quality of care provided by participating institutions through feedback concerning results for each institution; and (4) perform additional studies to explore specific clinical research questions. We conducted a cross-sectional, anonymous, self-report questionnaire survey involving patients' bereaved family members in 20 acute hospitals, 133 PCUs, and 22 home hospice services between May and July 2014. Two types of questionnaires were used: main and specific studies questionnaires. The questionnaire was sent to totally 13 584, and 10 157 returned the questionnaire. The analysis included 9126 family members' questionnaires from acute hospitals, PCUs, and home hospice services. Respondents' average age was 61.6 years, 55% were women, and 40% had been married to the deceased. With respect to the characteristics of participating institutions, most institutions did not have religious affiliations, and most PCUs and home hospice services provided bereavement care. These results of the analysis of common and additional questionnaires could play an important role in clinical settings, quality improvement, research, and public accountability.

    Schaefer, Hans-Eckhardt

    2017-01-01

    The present study is focused on a review of the current state of investigating music-evoked emotions experimentally, theoretically and with respect to their therapeutic potentials. After a concise historical overview and a schematic of the hearing mechanisms, experimental studies on music listeners and on music performers are discussed, starting with the presentation of characteristic musical stimuli and the basic features of tomographic imaging of emotional activation in the brain, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), which offer high spatial resolution in the millimeter range. The progress in correlating activation imaging in the brain to the psychological understanding of music-evoked emotion is demonstrated and some prospects for future research are outlined. Research in psychoneuroendocrinology and molecular markers is reviewed in the context of music-evoked emotions and the results indicate that the research in this area should be intensified. An assessment of studies involving measuring techniques with high temporal resolution down to the 10 ms range, as, e.g., electroencephalography (EEG), event-related brain potentials (ERP), magnetoencephalography (MEG), skin conductance response (SCR), finger temperature, and goose bump development (piloerection) can yield information on the dynamics and kinetics of emotion. Genetic investigations reviewed suggest the heredity transmission of a predilection for music. Theoretical approaches to musical emotion are directed to a unified model for experimental neurological evidence and aesthetic judgment. Finally, the reports on musical therapy are briefly outlined. The study concludes with an outlook on emerging technologies and future research fields. PMID:29225563

    In the context created by the French law on energy transition and green growth, this study addresses participative projects which are levers for the financing of renewable energy production, and also contribute to the local dimension of projects. More precisely, the authors focus on participative projects in which a financial participation of citizen and/or local communities is present, with or without access to governance, directly or indirectly. The authors first propose a typology of these projects, based on existing initiatives, and then an overview of the legal and regulatory framework in effect before the law on energy transition. They comment and discuss articles contained by this law which address citizen participation. They discuss their impact on the current project typology

    Family members of critically ill patients who participate in research focused on palliative care issues have been found to be systematically different from those who do not. These differences threaten the validity of research and raise ethical questions about worsening disparities in care by failing to represent diverse perspectives. This study's aims were to explore: 1) barriers and facilitators influencing family members' decisions to participate in palliative care research; and 2) potential methods to enhance research participation. Family members who were asked to participate in a randomized trial testing the efficacy of a facilitator to improve clinician-family communication in the intensive care unit (ICU). Family members who participated (n = 17) and those who declined participation (n = 7) in Family Communication Study were interviewed about their recruitment experiences. We also included family members of currently critically ill patients to assess current experiences (n = 4). Interviews were audio-recorded and transcribed. Investigators used thematic analysis to identify factors influencing family members' decisions. Transcripts were co-reviewed to synthesize codes and themes. Three factors influencing participants' decisions were identified: Altruism, Research Experience, and Enhanced Resources. Altruism and Research Experience described intrinsic characteristics that are less amenable to strategies for improving participation rates. Enhanced Resources reflects families' desires for increased access to information and logistical and emotional support. Family members found their recruitment experiences to be positive when staff were knowledgeable about the ICU, sensitive to the stressful circumstances, and conveyed a caring attitude. By training research staff to be supportive of families' emotional needs and need for logistical knowledge about the ICU, recruitment of a potentially more diverse sample of families may be enhanced.

    Recent innovations in gene analysis technology have allowed for rapid and inexpensive sequencing of entire genomes. Thus, both conducting a study using whole genome sequencing (WGS) in a large population and the clinical application of research findings from such studies are currently feasible. However, to promote WGS studies, understanding and voluntary participation by the general public is needed. Therefore, it is essential to investigate the general public's attitude toward and understanding of WGS studies. The primary goal of our research is to investigate these issues and to discover how they relate to research participation in WGS studies. A survey of awareness regarding WGS and studies using WGS was conducted with a sample of 2000 or more participants using a self-administered questionnaire posted on the Internet between February 20 and 21, 2015. Prior to the survey, we briefly explained WGS and WGS study-related issues to the respondents in order to provide them with the minimum knowledge required to answer the questionnaire. We then conducted an analysis, including cross-classification. For the question regarding interest in WGS, 46.6% of participants responded "Yes." 70.7% of all respondents said that they were interested in some kinds of findings that could be obtained from WGS studies. Regarding participation in WGS studies, 29.0% were interested in participating. The demographic factors significantly related to attitudes toward research participation were age, level of education, and employment status. The results also suggest that concerns about WGS have a positive effect on people's willingness to participate. Furthermore, it was shown that for people who were not interested in their gene-related information, concerns about WGS negatively impacted their willingness to participate. However, for people who were interested in their gene-related information, their concerns might not have impacted their willingness to participate. This research has shown

    The sequence of events in a behaviour change trial involves interactions between research participants and the trial process. Taking part in such a study has the potential to influence the behaviour of the participant, and if it does, this can engender bias in trial outcomes. Since participants' experience has received scant attention, the aim of this study is thus to generate hypotheses about which aspects of the conduct of behaviour change trials might matter most to participants, and thus have potential to alter subsequent behaviours and bias trial outcomes Twenty participants were opportunistically screened for a health compromising behaviour (unhealthy diet, lack of exercise, smoking or alcohol consumption) and recruited if eligible. Semi structured face to face interviews were conducted, after going through the usual processes involved in trial recruitment, baseline assessment and randomisation. Participants were given information on the contents of an intervention or control condition in a behaviour change trial, which was not actually implemented. Three months later they returned to reflect on these experiences and whether they had any effect on their behaviour during the intervening period. Data from the latter interview were analysed thematically using a modified grounded theory approach. The early processes of trial participation raised awareness of unhealthy behaviours, although most reported having had only fleeting intentions to change their behaviour as a result of taking part in this study, in the absence of interventions. However, careful examination of the accounts revealed evidence of subtle research participation effects, which varied according to the health behaviour, and its perceived social acceptability. Participants' relationships with the research study were viewed as somewhat important in stimulating thinking about whether and how to make lifestyle changes. These participants described no dramatic impacts attributable to taking part in

    This study explores current experience with posttraumatic stress disorder (PTSD) symptoms and other variables (sociodemographic, mental distress, somatic morbidity, self-rated health, and quality of life [QoL]) in relation to fatigue. A representative sample of the Norwegian population (N = 3,944) was invited to participate in a mailed survey, and 1,857 (47%) returned valid responses on the questionnaire that included the Fatigue Severity Scale and the Posttraumatic Symptom Scale-10. Posttraumatic stress disorder symptoms showed a strong association with fatigue in univariate (β = .41) and multivariate analyses (β = .33). Associations between psychosocial health variables, QoL, and fatigue were confirmed. However, PTSD symptoms showed the strongest association with fatigue in the analyses. Findings need to be replicated in other population samples and in clinical samples with PTSD and fatigue.

Studies which specifically manipulate catastrophizing are necessary to establish causation. The present study enrolled 100 healthy individuals. Participants were randomly assigned to repeat a positive, neutral, or one of three catastrophizing statements during a cold pressor task (CPT. Outcome measures of pain tolerance and pain intensity were recorded. No change was noted in catastrophizing immediately following the CPT (F(1,84 = 0.10, p = 0.75, partial η2 < 0.01 independent of group assignment (F(4,84 = 0.78, p = 0.54, partial η2 = 0.04. Pain tolerance (F(4 = 0.67, p = 0.62, partial η2 = 0.03 and pain intensity (F(4 = 0.73, p = 0.58, partial η2 = 0.03 did not differ by group. This study suggests catastrophizing may be difficult to manipulate through experimental pain procedures and repetition of specific catastrophizing statements was not sufficient to change levels of catastrophizing. Additionally, pain tolerance and pain intensity did not differ by group assignment. This study has implications for future studies attempting to experimentally manipulate pain catastrophizing.Keywords: pain, catastrophizing, experimental, cold pressor task, pain catastrophizing scale

  17. Experimental studies of coaxial plasma gun current

    Price, D.W.

    1988-01-01

    In this investigation of a coaxial plasma gun, plasma sheath currents and related behavior are examined. Plasma behavior in the gun affects gun characteristics. Plasma gun applications are determined by the plasma behavior. The AFWL PUFF capacitor bank (72 μF, 29 nH, 120 kV) drives the plasma gun using a deuterium fill gas. The gas breakdown site is isolated from the dielectric/vacuum interface in the AFWL system. Two gas values deliver gas in the system. The first delivers gas from the gun breech and the second optional valve delivers gas to the gun muzzle. Currents and voltages are measured by Rogowski coils, B probes and capacitive voltage probes. A O-D slug model is used to predict the current, inductance, gun voltage and plasma sheath velocity. The slug model assumes the sheath transits the gun with all mass in the sheath. In the snowplow mode, the plasma sheath is thin with a sharp current rise and drop. Our system operated in a transition mode between the snowplow and deflagration modes with early snowplow behavior and late deflagration behavior. Neutrons are produced in a plasma pinch at the gun muzzle, indicating snowplow behavior. The slug theory models overall gun behavior to experimental accuracy. Experimental results are compared to four theories for plasma sheath velocities: the Alfven collisionally limited model, the Rosenbluth model, the Fishbine saturated model and a single particle drift model. Experimental velocities vary from 10 5 to 10 6 m/s. Only the single particle drift and the slug model calculations are of the right magnitude (8 x 10 5 m/s). The Fishbine and the Rosenbluth models predict slower velocities (2 x 10 5 m/s). The Alfven model is not applicable to this system

    1989-11-01

    To assess ultrasonography's capabilities in the detection of cancer and other diseases, abdominal ultrasonographic screening was performed for 3,707 Hiroshima and 2,294 Nagasaki atomic bomb survivors and comparison subjects who participated in the Adult Health Study from 1 November 1981 to 31 October 1985 in Hiroshima and from 1 August 1984 to 31 July 1986 in Nagasaki. A total of 20 cancers was detected, consisting of 7 hepatomas, 3 gastric cancers, 3 renal cancers, 2 cancers of the urinary bladder, and 1 cancer each of the ovary, pancreas, colon, ureter and liver (metastatic). The cancer detection rate was 0.33 %. The diagnoses of seven cancer subjects in each city were subsequently confirmed at autopsy or surgery; diagnoses of four cancer subjects in Hiroshima and two in Nagasaki were obtained from death certificates. Among the 20 cancer patients, 13 were asymptomatic. After the ultrasonographic detection and diagnosis of these 20 cancers, the medical records of each of the 20 cancer patients were reviewed for any evidence of cancer detection by other examining techniques, and the records of only 3 patients revealed such recent detection. The tumor and tissue registries were similarly checked, but no evidence of earlier diagnosis of their disease was found. Ten of the cancer patients had received ionizing radiation doses from the A-bombs ranging up to 3,421 mGy (DS86), but no correlation was established between cancer prevalence and the A-bomb doses. A variety of tumors, 259 in number and most probably benign, were also detected with ultrasonography. In addition, numerous other abnormalities were diagnosed, with prevalences of 7.7 % for cholelithiasis, 5.7 % for renal cysts, and 3.8 % for liver cysts. No statistical analysis was performed concerning the prevalence of the diseases detected. (author)

    Strong nonpainful transcutaneous electrical nerve stimulation (TENS) is prerequisite to a successful analgesic outcome although the ease with which this sensation is achieved is likely to depend on the magnitude of current amplitude (mA) between sensory detection threshold (SDT) and pain threshold, that is, the current window. To measure the current window and participant's perception of the comfort of the TENS sensation at different body sites. A repeated measure cross-over study was conducted using 30 healthy adult volunteers. Current amplitudes (mA) of TENS [2 pulses per second (pps); 30 pps; 80 pps] at SDT, pain threshold, and strong nonpainful intensities were measured at the tibia (bone), knee joint (connective tissue), lower back [paraspinal (skeletal) muscle], volar surface of forearm (nerve) and waist (fat). The amplitude to achieve a strong nonpainful intensity was represented as a percentage of the current window. Data were analyzed using repeated measures analysis of variance. Effects were detected for body site and frequency for SDT (PTENS as a percentage of the current window (P=0.002, PTENS as most comfortable at the lower back (PTENS is most comfortable and easiest to titrate to a strong nonpainful intensity when applied over areas of muscle and soft tissue.

    The current methods measuring sports activity after anterior cruciate ligament (ACL) injury are commonly restricted to the most knee-demanding sports, and do not consider participation in multiple sports. We therefore developed an online activity survey to prospectively record the monthly participation in all major sports relevant to our patient-group. To assess the reliability, content validity and concurrent validity of the survey and to evaluate if it provided more complete data on sports participation than a routine activity questionnaire. 145 consecutively included ACL-injured patients were eligible for the reliability study. The retest of the online activity survey was performed 2 days after the test response had been recorded. A subsample of 88 ACL-reconstructed patients was included in the validity study. The ACL-reconstructed patients completed the online activity survey from the first to the 12th postoperative month, and a routine activity questionnaire 6 and 12 months postoperatively. The online activity survey was highly reliable (κ ranging from 0.81 to 1). It contained all the common sports reported on the routine activity questionnaire. There was a substantial agreement between the two methods on return to preinjury main sport (κ=0.71 and 0.74 at 6 and 12 months postoperatively). The online activity survey revealed that a significantly higher number of patients reported to participate in running, cycling and strength training, and patients reported to participate in a greater number of sports. The online activity survey is a highly reliable way of recording detailed changes in sports participation after ACL injury. The findings of this study support the content and concurrent validity of the survey, and suggest that the online activity survey can provide more complete data on sports participation than a routine activity questionnaire.

    Turbulent natural convection in a tall differentially heated cavity of aspect ratio 5:1, filled with air under a Rayleigh number based on the height of 4.5·10 10 is studied numerically. Three different situations have been analysed. In the first one, the cavity is filled with a transparent medium. In the second one, the cavity is filled with a semigrey participating mixture of air and water vapour. In the last one the cavity contains a grey participating gas. The turbulent flow is described by means of Large Eddy Simulation (LES) using symmetry-preserving discretizations. Simulations are compared with experimental data available in the literature and with Direct Numerical Simulations (DNS). Surface and gas radiation have been simulated using the Discrete Ordinates Method (DOM). The influence of radiation on fluid flow behaviour has been analysed.

    Agricultural exposures including pesticides, endotoxin, and allergens have been associated with risk of various cancers and other chronic diseases, although the biological mechanisms underlying these associations are generally unclear. To facilitate future molecular epidemiologic investigations, in 2010 the study of Biomarkers of Exposure and Effect in Agriculture (BEEA) was initiated within the Agricultural Health Study, a large prospective cohort in Iowa and North Carolina. Here the design and methodology of BEEA are described and preliminary frequencies for participant characteristics and current agricultural exposures are reported. At least 1,600 male farmers over 50 years of age will be enrolled in the BEEA study. During a home visit, participants are asked to complete a detailed interview about recent agricultural exposures and provide samples of blood, urine, and (since 2013) house dust. As of mid-September 2014, in total, 1,233 participants have enrolled. Most of these participants (83%) were still farming at the time of interview. Among those still farming, the most commonly reported crops were corn (81%) and soybeans (74%), and the most frequently noted animals were beef cattle (35%) and hogs (13%). There were 861 (70%) participants who reported occupational pesticide use in the 12 months prior to interview; among these participants, the most frequently noted herbicides were glyphosate (83%) and 2,4-D (72%), and most commonly reported insecticides were malathion (21%), cyfluthrin (13%), and permethrin (12%). Molecular epidemiologic investigations within BEEA have the potential to yield important new insights into the biological mechanisms through which these or other agricultural exposures influence disease risk.

    The studies on nodular corrosion formed on the outer surface of BWR fuel cladding tubes were reviewed. Main factors affecting the corrosion behavior were material and environmental conditions and combined effect. The effects of such material conditions as fabrication process, alloy elements, texture and surface treatment and environmental factors as neutron irradiation, thermo-hydrodynamic, water chemistry, purity of the coolant and contact with foreign metals on the corrosion phenomena were surveyed. Out-of-reactor corrosion test methods and models for the corrosion mechanism were also reviewed. Suppression of the accumulated annealing temperature during tube reduction process improved the nodular corrosion resistance of Zircaloys. Improved resistance for the nodular corrosion was reported for the unirradiated Zircaloys with some additives. Detailed irradiation test under the BWR conditions is needed to confirm the trend. Concerning the environmental factors, boiling on the cladding surface due to heat flux reduces the nodular corrosion susceptibility, while oxidizing radical generated from dissolved oxygen accelerates the corrosion. Concerning corrosion mechanisms, importance of such phenomena as the depleted zone of alloying elements in zirconium matrix, reduction of H + to H 2 in oxide layer, electrochemical property of precipitates, crystallographic anisotropy of oxidation rates were revealed.

    Full Text Available Life expectancy for people diagnosed with HIV has improved dramatically however the number of new infections in the UK remains high. Understanding patterns of sexual behaviour among people living with diagnosed HIV, and the factors associated with having condom-less sex, is important for informing HIV prevention strategies and clinical care. In addition, in view of the current interest in a policy of early antiretroviral treatment (ART for all people diagnosed with HIV in the UK, it is of particular importance to assess whether ART use is associated with increased levels of condom-less sex. In this context the ASTRA study was designed to investigate current sexual activity, and attitudes to HIV transmission risk, in a large unselected sample of HIV-infected patients under care in the UK. The study also gathered background information on demographic, socio-economic, lifestyle and disease-related characteristics, and physical and psychological symptoms, in order to identify other key factors impacting on HIV patients and the behaviours which underpin transmission. In this paper we describe the study rationale, design, methods, response rate and the demographic characteristics of the participants. People diagnosed with HIV infection attending 8 UK HIV out-patient clinics in 2011-2012 were invited to participate in the study. Those who agreed to participate completed a confidential, self-administered pen-and-paper questionnaire, and their latest CD4 count and viral load test results were recorded. During the study period, 5112 eligible patients were invited to take part in the study and 3258 completed questionnaires were obtained, representing a response rate of 64% of eligible patients. The study includes 2248 men who have sex with men (MSM, 373 heterosexual men and 637 women. Future results from ASTRA will be a key resource for understanding HIV transmission within the UK, targeting prevention efforts, and informing clinical care of individuals

    This pilot study explored the experience of participating in a Therapeutic Touch practice group. A qualitative descriptive-exploratory method was used, involving 12 members of practice groups in Ontario and British Columbia, Canada. Analysis of the data using an extraction-synthesis process yielded four themes: (a) learning with others through sharing and hands-on experience is valued; (b) connecting with a network of supportive relationships that sustain self and Therapeutic Touch practice; (c) comfort-discomfort arising with self, others, or ideas; and (d) meaningful changes emerge while experiencing group energy and Therapeutic Touch. The findings expand current knowledge about the positive aspects of participating in practice groups and provide a beginning understanding of member discomfort, which had not been previously reported. This knowledge will be useful to Therapeutic Touch organizations, practice group leaders, and group members. It will also guide health care agencies and practitioners of other healing modalities who may be considering establishing practice groups.

    Sport participation can play an important and positive role in the health and development of children and youth. One area that has recently been receiving greater attention is the role that sport participation might play in preventing drug and alcohol use among youth. The current study is a systematic review of 17 longitudinal studies examining the relationship between sport participation and alcohol and drug use among adolescents. Results indicated that sport participation is associated with alcohol use, with 82% of the included studies (14/17) showing a significant positive relationship. Sport participation, however, appears to be related to reduced illicit drug use, especially use of non-cannabis related drugs. Eighty percent of the studies found sport participation associated with decreased illicit drug use, while 50% of the studies found negative association between sport participation and marijuana use. Further investigation revealed that participation in sports reduced the risk of overall illicit drug use, but particularly during high school; suggesting that this may be a critical period to reduce or prevent the use of drugs through sport. Future research must better understand what conditions are necessary for sport participation to have beneficial outcomes in terms of preventing alcohol and/or illicit drug use. This has been absent in the extent literature and will be central to intervention efforts in this area. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Evaluation of the original ParticipACTION campaign effects focused on individual awareness, recall, and understanding. Less studied has been the impact such campaigns have had on the broader organizational capacity to mobilize and advocate for physical activity. With the relaunch of ParticipACTION, the purpose of this study was to qualitatively explore baseline organizational capacity to promote physical activity messages, programs, and services within the Canadian context. Methods Using a purposeful sampling strategy, we conducted semi-structured telephone interviews with 49 key informants representing a range of national, provincial, and local organizations with a mandate to promote physical activity. Interview data were analysed using a thematic analytic approach. Results Key informants painted a generally positive picture of current organizational capacity to promote physical activity messages, programs, and services in Canada. Will and leadership were clear strengths while infrastructure limitations remained the greatest concern. Some specific challenges included: 1 funding issues: the absence of core funding in a climate of shifting funding priorities; 2 the difficulty of working without a national physical activity policy (lack of leadership; 3 inconsistent provincial and educational sector level policies; and 4 a persistent focus on obesity rather than physical inactivity. Conclusion The data generated here can be utilized to monitor the future impact of ParticipACTION on enhancing and utilizing this organizational capacity. A range of indicators are suggested that could be used to illustrate ParticipACTION's impact on the broad field of physical activity promotion in the future.

    Full Text Available Abstract Background Recruitment rates of older people in epidemiological studies, although relatively higher than in clinical trials, have declined in recent years. This study aimed to explore motivating factors and concerns among older participants in an intensive epidemiological study (Hertfordshire Sarcopenia Study - HSS and identify those that could aid future recruitment to epidemiological studies and clinical trials. Methods Participants of the HSS fasted overnight and travelled several hours each way to the research facility at an English hospital for extensive diet/lifestyle questionnaires and investigations to assess muscle including blood tests and a muscle biopsy. We conducted semi-structured interviews with 13 participants (ten women at the research facility in May–October 2015. The interviews were audio-taped, transcribed verbatim, coded and analysed thematically by three researchers. Results We identified personal motives for participation (potential health benefit for self and family; curiosity; comparing own fitness to others; socialising. Altruistic motives (benefit for other people; belief in importance of research were also important. Participants voiced a number of external motives related to the study uniqueness, organisation and safety record; family support; and just ‘being asked’. Anxiety about the biopsy and travel distance were the only concerns and were alleviated by smooth and efficient running of the study. Conclusions Personal and altruistic reasons were important motivators for these older people to participate in demanding, intensive research. They valued belonging to a birth cohort with previous research experience, but personal contact with the research team before and after consent provided reassurance, aided recruitment to HSS and could be readily replicated by other researchers. Any fears or concerns related to certain aspects of a demanding, intensive study should ideally be explored at an early visit

    Increasing the number of patients participating in research studies is a current priority in the National Health Service (NHS) in the United Kingdom. The role of specialist nurses in inviting patients to participate is important, yet little is known about their experiences of doing so. The aim of this study was to explore the perceptions of barriers and facilitators held by specialist nurses with experience of inviting adult NHS patients to a wide variety of research studies. A cross-sectional qualitative descriptive study was conducted between March and July 2015. Participants were 12 specialist nurses representing 7 different clinical specialties and 7 different NHS Trusts. We collected data using individual semi-structured interviews, and analysed transcripts using the Framework method to inductively gain a descriptive overview of barriers and facilitators. Barriers and facilitators were complex and interdependent. Perceptions varied among individuals, however barriers and facilitators centred on five main themes: i) assessing patient suitability, ii) teamwork, iii) valuing research, iv) the invitation process and v) understanding the study. Facilitators to inviting patients to participate in research often stemmed from specialist nurses' attitudes, skills and experience. Positive research cultures, effective teamwork and strong relationships between research and clinical teams at the local clinical team level were similarly important. Barriers were reported when specialist nurses felt they were providing patients with insufficient information during the invitation process, and when specialist nurses felt they did not understand studies to their satisfaction. Our study offers several new insights regarding the role of specialist nurses in recruiting patients for research. It shows that strong local research culture and teamwork overcome some wider organisational and workload barriers reported in previous studies. In addition, and in contrast to common practice

    Rather than providing participants with study-specific data collection devices, their personal mobile phones are increasingly being used as a means for collecting geolocation and ecological momentary assessment (EMA) data in public health research. The purpose of this study was to (1) describe the sociodemographic characteristics of respondents to an online survey screener assessing eligibility to participate in a mixed methods study collecting geolocation and EMA data via the participants' personal mobile phones, and (2) examine how eligibility criteria requiring mobile phone ownership and an unlimited text messaging plan affected participant inclusion. Adult (≥18 years) daily smokers were recruited via public advertisements, free weekly newspapers, printed flyers, and word of mouth. An online survey screener was used as the initial method of determining eligibility for study participation. The survey screened for twenty-eight inclusion criteria grouped into three categories, which included (1) cell phone use, (2) tobacco use, and (3) additional criteria. A total of 1003 individuals completed the online screener. Respondents were predominantly African American (605/1003, 60.3%) (60.4%), male (514/1003, 51.3%), and had a median age of 35 years (IQR 26-50). Nearly 50% (496/1003, 49.5%) were unemployed. Most smoked menthol cigarettes (699/1003, 69.7%), and had a median smoking history of 11 years (IQR 5-21). The majority owned a mobile phone (739/1003, 73.7%), could install apps (86.8%), used their mobile phone daily (89.5%), and had an unlimited text messaging plan (871/1003, 86.8%). Of those who completed the online screener, 302 were eligible to participate in the study; 163 were eligible after rescreening, and 117 were enrolled in the study. Compared to employed individuals, a significantly greater proportion of those who were unemployed were ineligible for the study based on mobile phone inclusion criteria (Pmobile phone inclusion criteria.

    Mie Medical Network of Breast Cancer Screening, a NPO, was assigned the task of breast cancer screening in Mie prefecture in April, 2010. For breast cancer screening in Mie prefecture in 2009, a questionnaire survey was performed toward both consigner and consignee. Consigners were local public offices managing breast cancer screening for local inhabitants, and consignees were facilities offering breast cancer screening. The number of breast cancer screening was investigated toward all 29 of consigners in Mie prefecture. The questionnaire survey was conducted toward all 52 of the facilities possessing mammography systems (breast cancer screening being performed at 48 of them) in Mie prefecture in 2009. We investigated the predictive additional number of breast cancer screening and also investigated the requisite number of staff to achieve the predictive maximum number of breast cancer screening. As a result, the total number of breast cancer screenings was 93,525, and the participation rate was 27.5% which was calculated by reduction of continuator in Mie prefecture in 2009. The continuator accounted for over 30% of all breast cancer screenings. The predictive additional number was 126,950, this indicates that a possible participation rate of 75.2% after 2011. To achieve this high participation rate, active support is essential for short-handed facilities, and about 20% increase of medical staff is necessary. To achieve a participation rate of over 50% as a goal, new screenees should be recruited and breast cancer screening of every other year should be enlightened. (author)

  9. Participant dropout as a function of survey length in internet-mediated university studies: implications for study design and voluntary participation in psychological research.

    2010-12-01

    Internet-mediated research has offered substantial advantages over traditional laboratory-based research in terms of efficiently and affordably allowing for the recruitment of large samples of participants for psychology studies. Core technical, ethical, and methodological issues have been addressed in recent years, but the important issue of participant dropout has received surprisingly little attention. Specifically, web-based psychology studies often involve undergraduates completing lengthy and time-consuming batteries of online personality questionnaires, but no known published studies to date have closely examined the natural course of participant dropout during attempted completion of these studies. The present investigation examined participant dropout among 1,963 undergraduates completing one of six web-based survey studies relatively representative of those conducted in university settings. Results indicated that 10% of participants could be expected to drop out of these studies nearly instantaneously, with an additional 2% dropping out per 100 survey items included in the study. For individual project investigators, these findings hold ramifications for study design considerations, such as conducting a priori power analyses. The present results also have broader ethical implications for understanding and improving voluntary participation in research involving human subjects. Nonetheless, the generalizability of these conclusions may be limited to studies involving similar design or survey content.

    We studied cortical morphology in relation to sports participation and type of sport using a large sample of healthy children (n = 911). Sports participation data was collected through a parent-reported questionnaire. Magnetic resonance scans were acquired, and different morphological brain features were quantified. Global volumetric measures were not associated with sports participation. We observed thicker cortex in motor and premotor areas associated with sports participation. In boys, team sports participation, relative to individual sports, was related to thinner cortex in prefrontal brain areas involved in the regulation of behaviors. This study showed a relationship between sports participation and brain maturation.

    Full Text Available Abstract The proportion of non-participation in cohort studies, if associated with both the exposure and the probability of occurrence of the event, can introduce bias in the estimates of interest. The aim of this study is to evaluate the impact of participation and its characteristics in longitudinal studies. A systematic review (MEDLINE, Scopus and Web of Science for articles describing the proportion of participation in the baseline of cohort studies was performed. Among the 2,964 initially identified, 50 were selected. The average proportion of participation was 64.7%. Using a meta-regression model with mixed effects, only age, year of baseline contact and study region (borderline were associated with participation. Considering the decrease in participation in recent years, and the cost of cohort studies, it is essential to gather information to assess the potential for non-participation, before committing resources. Finally, journals should require the presentation of this information in the papers.

  15. The "participating victim" in the study of erotic experiences between children and adults: an historical analysis.

    Malón, Agustín

    2011-02-01

    During the 20th century, erotic experiences between minors and adults occupied a position of increasing interest, both public as well as scientific. In this area of research, one of the most notable evolutions in how these experiences are treated has been the progressive disappearance and/or the intense redefinition of what earlier researchers called "participating victims," i.e., minors apparently interested in accepting and/or sustaining these relationships. The present work, through a comparative analysis of the literature, seeks to substantiate this transformation during the second third of the 20th century. It will also argue that this evolution can be fundamentally explained in terms of the intense emotional, moral, and ideological importance that is ascribed to these experiences in the rise of the current victimological paradigm. Finally, this study endeavors to contribute to the understanding of childhood and the scientific study of child sexuality as well as of these experiences with adults.

    2008-01-01

    This study examines the current prospects for and obstacles facing the implementation of social impact assessment (SIA) and participatory planning in the People's Republic of China. During the past two decades, rapid urbanisation and the conversion of rural land for urban development have led to numerous social conflicts and tensions between the Chinese government and its people. SIA and public participation in development decisions have received increasing attention from the Chinese authorities as possible ways to tackle the problem. Based on a Guangzhou case study, this paper argues that the assessment and mitigation of adverse impacts on the community from urban development have been carried out with different objectives, core values and principles when compared with those in Western societies. It concludes that the poor prospects of SIA and collaborative planning in China lie not only in the weak framework for environmental legislation, but also in all institutions concerning state-society relations, the socialist governing ideology and traditional Chinese culture

    The challenges of global ageing and the growing burden of chronic diseases require innovative interventions acting on health determinants like social participation. Many older adults do not have equitable opportunities to achieve full social participation, and interventions might underempower their personal and environmental resources and only reach a minority. To optimise current practices, the Accompagnement-citoyen Personnalisé d'Intégration Communautaire (APIC), an intervention demonstrated as being feasible and having positive impacts, needs further evaluation. A pragmatic multicentre, prospective, two-armed, randomised controlled trial will evaluate: (1) the short-term and long-term effects of the APIC on older adults' health, social participation, life satisfaction and healthcare services utilisation and (2) its cost-effectiveness. A total of 376 participants restricted in at least one instrumental activity of daily living and living in three large cities in the province of Quebec, Canada, will be randomly assigned to the experimental or control group using a centralised computer-generated random number sequence procedure. The experimental group will receive weekly 3-hour personalised stimulation sessions given by a trained volunteer over the first 12 months. Sessions will encourage empowerment, gradual mobilisation of personal and environmental resources and community integration. The control group will receive the publicly funded universal healthcare services available to all Quebecers. Over 2 years (baseline and 12, 18 and 24 months later), self-administered questionnaires will assess physical and mental health (primary outcome; version 2 of the 36-item Short-Form Health Survey, converted to SF-6D utility scores for quality-adjusted life years), social participation (Social Participation Scale) and life satisfaction (Life Satisfaction Index-Z). Healthcare services utilisation will be recorded and costs of each intervention calculated. The Research

  19. The potential therapeutic value for bereaved relatives participating in research: An exploratory study.

    Conducting research with the bereaved presents an immediate ethical challenge, as they are undoubtedly a vulnerable group, associated with high levels of distress and susceptible to both physical and mental health issues. A comprehensive understanding of the potential therapeutic benefits for bereaved relatives participating in palliative care research is limited, and therefore the ethics of engaging this group remain questionable. This paper describes a secondary analysis of qualitative data collected in the Care of the Dying Evaluation (CODE) project, examining the experiences of patients who died at home. It explores the motivations and potential benefits for bereaved relatives participating in research with reference to the recently developed concepts in bereavement theory. Cognitive interviews were conducted with 15 bereaved relatives and secondary analysis using a content analysis framework was employed to classify the data. The results center around six recurring concepts identified as adaptive in current bereavement theory: an opportunity to share the narrative accounts of the final hours of their relative's life; a search for sense and meaning in loss; an ongoing bond/attachment with the deceased; altruistic motivations; oscillation between loss and restorative orientations; and a sense of resilience. Overall, the participants found that taking part in the research was valuable and that it could be described as offering therapeutic benefits. The need for bereaved relatives to take part in research studies should be encouraged, as they provide an accurate proxy for the patient's experience of end-of-life care while also providing a valuable account of their own perspective as family member and carer. In addition, we highlight the need for ethics committees to be aware of the potential benefits for bereaved relatives participating in research of this kind.

    The current study had three aims. First, it measured treatment readiness among offenders who entered the Prevention of Recidivism program. This is a prison-based rehabilitation program in the Netherlands that aims to lower re-offending rates among offenders with a prison sentence of at least for months and that is carried out during the final months of incarceration. Second, the study evaluated whether treatment readiness was associated with treatment participation. Third, the study examined whether treatment readiness measured with a validated instrument predicted treatment participation above and beyond a clinical assessment of treatment readiness, currently used as a criterion to include offenders in rehabilitation programs. To address these aims, data were used from the fourth wave of a research project studying the effects of imprisonment on the life of detainees in the Netherlands. Results indicated that treatment readiness as measured with a validated instrument was a significant predictor of treatment participation. Also, the current study showed that treatment readiness measured with a validated instrument improved the prediction of treatment participation above and beyond a clinical assessment of treatment readiness. Outcomes were discussed in light of study limitations and implications.

    To investigate healthcare professionals' perspectives on child participation in paediatric hospital care and their opinions on improving participation practices. Some scholars argue that the decision-making capacities of children largely depend on the attitudes of healthcare professionals rather than on the children's own competences. Healthcare professionals' perspectives on children's participation in hospital care remain largely unexplored. Qualitative descriptive design. Healthcare professionals (n = 32) from 10 paediatric wards in the Netherlands participated in semi-structured interviews. Shier's Pathways to Participation model (2001) was used to guide the interviews. Participation is not a term that is frequently used by professionals; however, they feel familiar with the ideas underlying the term, and it is perceived as being at the core of their work. Professionals believe that high levels of participation are possible in basic care for children. Participation in medical decision-making is considered to be more complex and subject to a number of reservations and restrictions. The participants expressed a strong need to enhance child participation in service evaluation and to increase the respect for and understanding of the rights of children to participate outside of the paediatric unit, including in the surgery and emergency departments. Children do not currently participate in the assessment of hospital services. Creative methods that support the role of children in evaluating and improving the quality of paediatric hospital care and services should be developed. Hospital-wide policies could help to promote understanding of child participation among all professionals caring for children in hospitals. Based on international agreements that the Netherlands has ratified, professionals have the duty to facilitate child participation in hospital care. Concrete opportunities and ideas on how to accomplish this goal in practice are provided, and areas for

    Full Text Available BACKGROUND: Many double-blind clinical trials of transcranial direct current stimulation (tDCS use stimulus intensities of 2 mA despite the fact that blinding has not been formally validated under these conditions. The aim of this study was to test the assumption that sham 2 mA tDCS achieves effective blinding. METHODS: A randomised double blind crossover trial. 100 tDCS-naïve healthy volunteers were incorrectly advised that they there were taking part in a trial of tDCS on word memory. Participants attended for two separate sessions. In each session, they completed a word memory task, then received active or sham tDCS (order randomised at 2 mA stimulation intensity for 20 minutes and then repeated the word memory task. They then judged whether they believed they had received active stimulation and rated their confidence in that judgement. The blinded assessor noted when red marks were observed at the electrode sites post-stimulation. RESULTS: tDCS at 2 mA was not effectively blinded. That is, participants correctly judged the stimulation condition greater than would be expected to by chance at both the first session (kappa level of agreement (κ 0.28, 95% confidence interval (CI 0.09 to 0.47 p=0.005 and the second session (κ=0.77, 95%CI 0.64 to 0.90, p=<0.001 indicating inadequate participant blinding. Redness at the reference electrode site was noticeable following active stimulation more than sham stimulation (session one, κ=0.512, 95%CI 0.363 to 0.66, p<0.001; session two, κ=0.677, 95%CI 0.534 to 0.82 indicating inadequate assessor blinding. CONCLUSIONS: Our results suggest that blinding in studies using tDCS at intensities of 2 mA is inadequate. Positive results from such studies should be interpreted with caution.

    The Japanese Study on Stratification, Health, Income, and Neighborhood (J-SHINE) aims to clarify the complex associations between social factors and health from an interdisciplinary perspective and to provide a database for use in various health policy evaluations. J-SHINE is an ongoing longitudinal panel study of households of adults aged 25-50 years. The wave 1 survey was carried out in 2010 among adults randomly selected from the resident registry of four urban and suburban municipalities in the greater Tokyo metropolitan area, Japan. In 2011, surveys for the participants' spouse/partner and child were additionally conducted. The wave 2 survey was conducted in 2012 for the wave 1 participants and will be followed by the wave 2 survey for spouse/partner and child in 2013. Wave 1 sample sizes were 4357 for wave 1 participants (valid response rate: 31.3%; cooperation rate: 51.8%), 1873 for spouse/partner (response rate: 61.9%), and 1520 for child (response rate: 67.7%). Wave 2 captured 69.0% of wave 1 participants. Information gathered covered socio-demographics, household economy, self-reported health conditions and healthcare utilization, stress and psychological values, and developmental history. A subpopulation underwent physiological (n = 2468) and biomarker (n = 1205) measurements. Longitudinal survey data, including repeated measures of social factors evaluated based on theories and techniques of various disciplines, like J-SHINE, should contribute toward opening a web of causality for society and health, which may have important policy implications for recent global health promotion strategies such as the World Health Organization's Social Determinants of Health approach and the second round of Japan's Healthy Japan 21.

    Community and neighbourhood structures contribute not only to the health and well-being, but also to the participation of older adults. The degree of participation depends on both the living environment and the individual's personal characteristics, preferences and perception. However, there is still limited empirical evidence on how community and neighbourhood structures are linked to participation and health in the aged population. A qualitative exploratory approach was chosen with a series of problem-centred, semi-structured focus group discussions. Study participants were selected from within the city of Augsburg, Southern Germany, and from two municipalities in surrounding rural districts. The interviews took place in 2013. Structuring content analysis was used to identify key concepts. We conducted 11 focus group discussions with a total of 78 different study participants. The study participants (33 men and 45 women) had a mean age of 74 years (range 65-92 years). Only two study participants lived in an assisted living facility. Of all study participants, 77% lived in urban and 23% in rural areas. We extracted four metacodes ('Usual activities', 'Requirements for participation', 'Barriers to participation' and 'Facilitators for participation') and 15 subcodes. Health and poorly designed infrastructure were mentioned as important barriers to participation, and friendship and neighbourhood cohesion as important facilitators. This qualitative study revealed that poor design and accessibility of municipal infrastructure are major barriers to participation in old age in Germany. Community and neighbourhood structures can be part of the problem but also part of the solution when accessibility and social networks are taken into account.

    Full Text Available Abstract Background Increasing the number of patients participating in research studies is a current priority in the National Health Service (NHS in the United Kingdom. The role of specialist nurses in inviting patients to participate is important, yet little is known about their experiences of doing so. The aim of this study was to explore the perceptions of barriers and facilitators held by specialist nurses with experience of inviting adult NHS patients to a wide variety of research studies. Methods A cross-sectional qualitative descriptive study was conducted between March and July 2015. Participants were 12 specialist nurses representing 7 different clinical specialties and 7 different NHS Trusts. We collected data using individual semi-structured interviews, and analysed transcripts using the Framework method to inductively gain a descriptive overview of barriers and facilitators. Results Barriers and facilitators were complex and interdependent. Perceptions varied among individuals, however barriers and facilitators centred on five main themes: i assessing patient suitability, ii teamwork, iii valuing research, iv the invitation process and v understanding the study. Facilitators to inviting patients to participate in research often stemmed from specialist nurses’ attitudes, skills and experience. Positive research cultures, effective teamwork and strong relationships between research and clinical teams at the local clinical team level were similarly important. Barriers were reported when specialist nurses felt they were providing patients with insufficient information during the invitation process, and when specialist nurses felt they did not understand studies to their satisfaction. Conclusion Our study offers several new insights regarding the role of specialist nurses in recruiting patients for research. It shows that strong local research culture and teamwork overcome some wider organisational and workload barriers reported in

    Americans' confidence in science varies based on their political ideology. This ideological divide has potentially important effects on citizens' engagement with and participation in clinical studies of Alzheimer disease (AD). A probability sample of 1583 Americans was surveyed about their willingness to participate in longitudinal AD research and about their political attitudes. These survey results were compared with a survey of 382 participants in a longitudinal AD study at the Knight Alzheimer Disease Research Center. Among Americans, more conservative ideology decreases willingness to participate in a hypothetical longitudinal cohort study of AD both directly and through its negative effect on confidence in science. The Knight Alzheimer Disease Research Center study participants expressed more liberal ideology and greater confidence in science than Americans in general. Of the survey respondents opposed to participation, over a quarter changed to neutral or positive if the study returned their research results to them. Clinical studies of AD are likely biased toward participants who are more liberal and have higher confidence in science than the general population. This recruitment bias may be reduced by lowering the trust demanded of participants through measures such as returning research results to participants.

    There is a growing body of evidence suggesting a link between sport participation and violent behavior outside of the sporting context. However, there have been few studies that have investigated the basis of this relationship. The current study examined longitudinal relationships between sport participation, problem alcohol use, and various violent behaviors, and whether sport participation moderates relationships between problem alcohol use and violence. The sample comprised 2,262 young adults (55% female, age range at Time 1 = 17-24 years) from Victoria, Australia, surveyed in 2010 and 2012. When controlling for common risk factors, substance use, and past violence, sport participation was not associated with any violent behaviors 2 years later. However, sport participation moderated the relationship between problem alcohol use and fighting, whereby problem alcohol use was associated with engaging in fights 2 years later for sport participants, but not for nonparticipants. These findings suggest that it is not sport participation per se that influences later violence but the drinking norms or culture embedded within certain sporting contexts. Prevention approaches that address the drinking culture and social approval of excessive alcohol consumption within sporting contexts may reduce the incidence of violent behavior in the community. © The Author(s) 2015.

    FEM-PrEP was unable to determine whether once-daily, oral emtricitabine/tenofovir disoproxil fumarate reduces the risk of HIV acquisition among women because of low adherence. Self-reported adherence was high, and pill-count data suggested good adherence. Yet, drug concentrations revealed limited pill use. We conducted a follow-up study with former participants in Bondo, Kenya, and Pretoria, South Africa, to understand factors that had influenced overreporting of adherence and to learn the whereabouts of unused pills. Qualitative, semistructured interviews were conducted with 88 participants, and quantitative, audio computer-assisted self-interviews were conducted with 224 participants. We used thematic analysis and descriptive statistics to analyze the qualitative and quantitative data, respectively. In audio computer-assisted self-interviews, 31% (n = 70) said they had overreported adherence; the main reason was the belief that nonadherence would result in trial termination (69%, n = 48). A considerable percentage (35%, n = 78) acknowledged discarding unused pills. Few acknowledged giving their pills to someone else (4%, n = 10), and even fewer acknowledged giving them to someone with HIV (2%, n = 5). Many participants in the semistructured interviews said other participants had counted and removed pills from their bottles to appear adherent. Despite repeated messages that nonadherence would not upset staff, participants acknowledged several perceived negative consequences of reporting nonadherence, which made it difficult to report accurately. Uneasiness continued in the follow-up study, as many said they had not overreported during the trial. Efforts to improve self-reported measures should include identifying alternative methods for creating supportive environments that allow participants to feel comfortable reporting actual adherence.

    This report describes a trade study of roles and responsibilities associated with the Management by Trajectory (MBT) concept. The MBT concept describes roles, responsibilities, and information and automation requirements for providing air traffic controllers and managers the ability to quickly generate, evaluate and implement changes to an aircraft's trajectory. In addition, the MBT concept describes mechanisms for imposing constraints on flight operator preferred trajectories only to the extent necessary to maintain safe and efficient traffic flows, and the concept provides a method for the exchange of trajectory information between ground automation systems and the aircraft that allows for trajectory synchronization and trajectory negotiation. The participant roles considered in this trade study include: airline dispatcher, flight crew, radar controller, traffic manager, and Air Traffic Control System Command Center (ATCSCC) traffic management specialists. The proposed allocation of roles and responsibilities was based on analysis of several use cases that were developed for this purpose as well as for walking through concept elements. The resulting allocation of roles and responsibilities reflects both increased automation capability to support many aviation functions, as well as increased flexibility to assign responsibilities to different participants - in many cases afforded by the increased automation capabilities. Note that the selection of participants to consider for allocation of each function is necessarily rooted in the current environment, in that MBT is envisioned as an evolution of the National Airspace System (NAS), and not a revolution. A key feature of the MBT allocations is a vision for the traffic management specialist to take on a greater role. This is facilitated by the vision that separation management functions, in addition to traffic management functions, will be carried out as trajectory management functions. This creates an opportunity

    Randomized controlled clinical trials are often considered to be the "gold standard" for health research. Consequently, understanding the reasons people participate in these trials, especially minority groups who are often under-represented in clinical trials, or populations who have chronic illnesses or abuse drugs, is salient for successful recruitment, retention, and project design. This paper describes the results of a study that was designed to examine some of the ways in which participants in a randomized double blind clinical trial perceived their participation in the clinical trial, and the reasons they gave for continuing in the study. All of the participants were individuals who were using drugs and were infected with the HIV-1 virus, and had participated in a chemoprevention trial. The data from an exit interview were analyzed thematically in order to reveal units of meaning concerning participation and continuation in the clinical trial. The analysis revealed 3 higher-level concepts, or themes, that guided participation: increased health awareness, personal enhancement, and sociability. The data clearly indicated that involvement and retention in the trial were directly related to the ways in which the participants interpreted the study, perceived the benefits they derived from participating, and imbued their participation with value so that it was important and relevant to their own perceptions of health, as well as personal and social well being.

  15. Extracurricular school-based sports as a motivating vehicle for sports participation in youth: a cross-sectional study

    2014-01-01

    Background Extracurricular school-based sports are considered to be an ideal means of reaching children who are not active in community sports. The purposes of this study were to examine the extent to which pupils not engaging in community sports do participate in extracurricular school-based sports, and to assess whether extracurricular school-based sports participants are more physically active and/or more autonomously motivated towards sports in daily life than children who do not participate in extracurricular school-based sports. Methods One thousand forty-nine children (53.7% boys; M age = 11.02 years, SD = 0.02) out of 60 classes from 30 Flemish elementary schools, with an extracurricular school-based sports offer, completed validated questionnaires to assess physical activity (Flemish Physical Activity Questionnaire) and motivation (Behavioral Regulations in Physical Education Questionnaire). Multilevel regression analyses were conducted to examine the data generated from these questionnaires. Results More than three quarters of the children (76%) reported participating in extracurricular school-based sports during the current school year and 73% reported engaging in organized community sports. Almost two third of the children (65%) not participating in community sports stated that they did participate in extracurricular school-based sports. Extracurricular school-based sports participants were significantly more physically active than children not participating in extracurricular school-based sports (β = 157.62, p sports participation × community sports participation) were found for autonomous motivation, with boys engaging in extracurricular school-based sports but not in community sports being significantly more autonomously motivated towards sports than boys not engaging in community or extracurricular school-based sports (β = 0.58, p = 0.003). Such differences were not noted among girls. Conclusions If extracurricular school-based sports are offered

    Full Text Available Background: Mobility impairments seen after Stroke impact walking speed, endurance and balance. Almost all the individuals with Stroke have fear of fall. The physical impairments in balance and gait along with individual’s perception about his/her own abilities to maintain balance might have an impact on level of activity and participation in the community. The association of these variables with recovery of Stroke has been well studied. However, it is currently unknown which of these variables are most associated with activity and participation in the community. This study aimed to identify the correlation of walking capacity and perception of fall with activity & participation. Methods: 30 Subjects were assessed for - walking capacity (6 minute walk test & Self-efficacy for falls (Modified Falls Efficacy scale. Level of Activity Limitation (AL & Participation Restriction (PR was graded on validated ICF Measure of Participation and Activities. (IMPACT-S Results: Data was analyzed using Pearson's correlation coefficient & regression model. Walking distance and Falls-efficacy is significantly correlated (r=-0.751 and -0.683, respectively with Participation restriction. Walking distance correlated with Activity Limitation (r=-0.714 significantly. Falls efficacy has a correlation coefficient of -0.642 with Activity Limitation. When put into Regression models, Walking Capacity & Gait Velocity was found to be independently associated with AL &PR. Conclusion: There is significant relationship between falls self-efficacy, walking capacity and Post-stroke activity & participation. Participation can be impacted by factors such as self-motivation and confidence about one's balance abilities. This is reflected by the correlation between falls efficacy and participation. Physical parameters such as the distance walked can contribute to participating in the community, and can predict variation in AL-PR

    Participation is an accepted means of increasing the effectiveness of public health programs, and as such, it is considered an important component of HIV interventions targeting at-risk youth. The situation of young women sex workers in Thailand is alarming on many fronts, including that of HIV risk. As a result, HIV programs in Thailand are the key interventions undertaken in relation to young women sex workers' health. A small-scale study used semistructured interviews to explore the participation reports of five young women sex workers, as well as the related views of two community support workers, who lived and worked in Bangkok, Thailand. This study is considered in the light of current research on - as well as new opportunities and challenges offered for - participation by vulnerable groups in the context of digital society. Thematic analysis of the interview data identified barriers to participation, including the illegality of sex work, fear, and lack of trust of the authorities, as well as widespread social stigma. Such barriers resulted in young women seeking anonymity. Yet, promisingly, young women positioned themselves as experts; they are involved in peer education and are supportive of greater involvement in HIV programs, such as further educational initiatives and collective actions. There is a need for a more empowerment-oriented participation practice positioning young women sex workers as expert educators and codecision makers within a model of participation that is also accountable, such as including young women as members of program boards. Beyond current norms, there are new opportunities emerging because of the increasing availability of smartphone/Internet technology. These can support activist and codesign participation by young women sex workers in HIV programs. However, any developments in participation must maximize opportunities carefully, taking into consideration the difficult social environment faced by young women sex workers as well

    Much environmental health research depends on human volunteers participating with biological samples. The perception study explores why and how people participate in a placenta perfusion study in Copenhagen. The participation implies donation of the placenta after birth and some background information but no follow up. Nineteen semi-structured qualitative interviews were conducted with participants in the placenta perfusion study after donation of placenta. Observation studies were made of recruitment sessions. The interviewed participants are generally in favour of medical research. They participated in the placenta perfusion study due to a belief that societal progress follows medical research. They also felt that participating was a way of giving something back to the Danish health care system. The participants have trust in medical science and scientists, but trust is something which needs to be created through "trust-work". Face-to-face interaction, written information material and informed consent forms play important parts in creating trusting relationships in medical research. Medical research ethics do not only amount to specific types of written information material but should also be seen as a number of trust making performances involving researchers as well as research participants.

    Few studies have systematically assessed the influence of gut microbiota on cardiovascular disease (CVD) risk. To examine the association between gut microbiota and lifetime CVD risk profile among 55 Bogalusa Heart Study participants with the highest and 57 with the lowest lifetime burdens of CVD risk factors. 16S ribosomal RNA sequencing was conducted on microbial DNA extracted from stool samples of the Bogalusa Heart Study participants. α Diversity, including measures of richness and evenness, and individual genera were tested for associations with lifetime CVD risk profile. Multivariable regression techniques were used to adjust for age, sex, and race (model 1), along with body mass index (model 2) and both body mass index and diet (model 3). In model 1, odds ratios (95% confidence intervals) for each SD increase in richness, measured by the number of observed operational taxonomic units, Chao 1 index, and abundance-based coverage estimator, were 0.62 (0.39-0.99), 0.61 (0.38-0.98), and 0.63 (0.39-0.99), respectively. Associations were consistent in models 2 and 3. Four genera were enriched among those with high versus low CVD risk profile in all models. Model 1 P values were 2.12×10(-3), 7.95×10(-5), 4.39×10(-4), and 1.51×10(-4) for Prevotella 2, Prevotella 7, Tyzzerella, and Tyzzerella 4, respectively. Two genera were depleted among those with high versus low CVD risk profile in all models. Model 1 P values were 2.96×10(-6) and 1.82×10(-4) for Alloprevotella and Catenibacterium, respectively. The current study identified associations of overall microbial richness and 6 microbial genera with lifetime CVD risk. © 2016 American Heart Association, Inc.

    A large fraction of the cost of conducting clinical trials is allocated to recruitment of participants. A synthesis of findings from studies that evaluate the cost and effectiveness of different recruitment strategies will inform investigators in designing cost-efficient clinical trials. To systematically identify, assess, and synthesize evidence from published comparisons of the cost and yield of strategies for recruitment of participants to health research studies. We included randomized studies in which two or more strategies for recruitment of participants had been compared. We focused our economic evaluation on studies that randomized participants to different recruitment strategies. We identified 10 randomized studies that compared recruitment strategies, including monetary incentives (cash or prize), direct contact (letters or telephone call), and medical referral strategies. Only two of the 10 studies compared strategies for recruiting participants to clinical trials. We found that allocating additional resources to recruit participants using monetary incentives or direct contact yielded between 4% and 23% additional participants compared to using neither strategy. For medical referral, recruitment of prostate cancer patients by nurses was cost-saving compared to recruitment by consultant urologists. For all underlying study designs, monetary incentives cost more than direct contact with potential participants, with a median incremental cost per recruitment ratio of Int$72 (Int$-International dollar, a theoretical unit of currency) for monetary incentive strategy compared to Int$28 for direct contact strategy. Only monetary incentives and source of referral were evaluated for recruiting participants into clinical trials. We did not review studies that presented non-monetary cost or lost opportunity cost. We did not adjust for the number of study recruitment sites or the study duration in our economic evaluation analysis. Systematic and explicit reporting of

    The aim of this study was to investigate if baseline motor competence, weight status and sports participation in early childhood predict sports participation two years later. longitudinal study. In 2010, motor competence (object control and locomotor skills), weight status and sports participation were assessed in 292 children between three and five years-of-age. In 2012, sports participation was re-evaluated in 206 of the original 292 children. Logistic regression was implemented to examine if initial sports participation, motor competence and weight status would predict sports participation two years later. In the final model, sports participation in 2010 (OR=9.68, CI: 3.46 to 27.13) and locomotor skills (OR=1.21, CI: 1.01 to 1.46) significantly predicted sports participation after two years. These results suggest that initial sports participation and more advanced locomotor skills in preschool years may be important to promote continued participation in sports across childhood.

    The aim of this study was to investigate why people with a first episode of psychosis choose or decline to participate in mental health research, using a qualitative study design. Participants were recruited via referrals from the Genetics and Psychosis (GAP) study. A total of 26 individuals with a first-episode of psychosis (nine of whom declined participation in the GAP study and 17 who participated) were individually interviewed and asked about their attitudes towards mental health research participation. Thematic analysis of interview transcripts was used to determine dominant themes and sub-themes on what constituted barriers and facilitators to participation. Reasons for research participation identified included a desire to help others, curiosity, and positive experiences with clinicians. Decisions to participate or not were also influenced by practical issues, including the timing of the approach, researchers' communication skills and whether individuals had concerns that it may be potentially harmful to their health. Other barriers to participation included patients' conceptualizations of mental health problems and the influence of other inpatients. Information on barriers and facilitators to recruitment in mental health research could inform recruitment strategies, thereby maximizing recruitment rates and minimizing the risk of selection biases.

    The high fraction of runaway current conversion following disruptions has an important effect on the first wall for next-generation tokamaks. Because of the potentially severe consequences of a large full current runaway beam on the first wall in an unmitigated disruption, runaway suppression is given a high priority. The behavior of runaway currents both in spontaneous disruptions and in D 2 massive gas injection (MGI) shutdown experiments is investigated in the KSTAR tokamak. The experiments in KSTAR show that the toroidal magnetic field threshold, B T >2 T, for runaway generation is not absolute. A high fraction of runaway current conversion following spontaneous disruptions is observed at a much lower toroidal magnetic field of B T = 1.3 T. A dedicated fast valve for high-pressure gas injection with 39.7 bar is developed for the study of disruptions. A study of runaway current parameters shows that the conversion efficiency of pre-disruptive plasma currents into runaway current can reach over 80% both in spontaneous disruptions and in D 2 MGI shutdown experiments in KSTAR.

    Full Text Available Objectives: The aim of this study was to assess the prevalence of cardiovascular risk factors in adults and their children from the 3 major groups of migrants participating in the PEP Family Heart Study [11] and to compare the cardio-metabolic risk profiles between migrants and German participants. Methods: In this community-based cross-sectional study, anthropometric data, blood pressure and lipid profiles of migrants (480 children, 363 adults from Turkey (TUR, Eastern Europe (EEU and German immigrants from the former Soviet Union (GFSU were compared with age and gender adjusted German (GER resi-dents (3253 children, 2491 adults. Results: The profile of risk factors differed considerably regarding specificity and frequency. The prevalence of ≥3 risk factors was as follows: in GFSU men 62%, women 36%, boys 19% and girls 17%; in TUR men 57%, women 30%, 15% boys and 6% girls; in GER men 48%, women 19%, boys 4% and girls 6%; for EEU men 38%, women 25% and 0% in children. No risk factor was present in GFSU men 13%, women 25%, boys 38% and girls 42%; TUR men 13%, women 28%, boys 27% and girls 22 %; GER men16%, women 45%, boys 46% and girls 41%; EEU men 17%, women 42 %, boys 29% and girls 27%. About 50% of the adults from Turkey and Eastern Europe were current smokers and one third of women and half of men from these two countries were over-weight. Conclusions: The implementation of primary care measures for the prevention of cardiovascular disease in migrants is necessary, and it should consider the ethnic differences and the heterogene-ous risk profiles.

    Over the past years knowledge about benefits of physical activity after cancer is evolving from randomized exercise intervention trials. However, it has been argued that results may be biased by selective participation. Therefore, we investigated factors influencing participation in a randomized exercise intervention trial for breast cancer patients. Non-metastatic breast cancer patients were systematically screened for a randomized exercise intervention trial on cancer-related fatigue. Participants and nonparticipants were compared concerning sociodemographic characteristics (age, marital status, living status, travel time to the training facility), clinical data (body-mass-index, tumor stage, tumor size and lymph node status, comorbidities, chemotherapy), fatigue, and physical activity. Reasons for participation or declination were recorded. 117 patients (52 participants, 65 nonparticipants) were evaluable for analysis. Multiple regression analyses revealed significantly higher odds to decline participation among patients with longer travel time (p = 0.0012), living alone (p = 0.039), with more comorbidities (0.031), previous chemotherapy (p = 0.0066), of age ≥ 70 years (p = 0.025), or being free of fatigue (p = 0.0007). No associations were found with BMI or physical activity. By far the most frequently reported reason for declination of participation was too long commuting time to the training facility. Willingness of breast cancer patients to participate in a randomized exercise intervention study differed by sociodemographic factors and health status. Neither current physical activity level nor BMI appeared to be selective for participation. Reduction of personal inconveniences and time effort, e.g. by decentralized training facilities or flexible training schedules, seem most promising for enhancing participation in exercise intervention trials.

    Research is being carried out to develop and test new potentially more effective tuberculosis vaccines. Among the vaccines being developed are those that target adolescents. This study explored the stakeholders' perceptions about adolescent participation in a hypothetical tuberculosis vaccine trial in Ugandan adolescents. Focus group discussions with adolescents, parents of infants and adolescents, and key informant interviews with community leaders and traditional healers were conducted. The majority of the respondents expressed potential willingness to allow their children participate in a tuberculosis vaccine trial. Main motivations for potential participation would be being able to learn about health-related issues. Hesitations included the notion that trial participation would distract the youths from their studies, fear of possible side effects of an investigational product, and potential for being sexually exploited by researchers. In addition, bad experiences from participation in previous research and doubts about the importance of research were mentioned. Suggested ways to motivate participation included: improved clarity on study purpose, risks, benefits and better scheduling of study procedures to minimize disruption to participants' academic schedules. Findings from this study suggest that the community is open to potential participation of adolescents in a tuberculosis vaccine trial. However, there is a need to communicate more effectively with the community about the purpose of the trial and its effects, including safety data, in a low-literacy, readily understood format. This raises a challenge to researchers, who cannot know all the potential effects of a trial product before it is tested.

    Abnormal motor cortex activity is common in dystonia. Cathodal transcranial direct current stimulation may alter cortical activity by decreasing excitability while anodal stimulation may increase motor learning. Previous results showed that a single session of cathodal transcranial direct current stimulation can improve symptoms in childhood dystonia. Here we performed a 5-day, sham-controlled, double-blind, crossover study, where we measured tracking and muscle overflow in a myocontrol-based task. We applied cathodal and anodal transcranial direct current stimulation (2 mA, 9 minutes per day). For cathodal transcranial direct current stimulation (7 participants), 3 subjects showed improvements whereas 2 showed worsening in overflow or tracking error. The effect size was small (about 1% of maximum voluntary contraction) and not clinically meaningful. For anodal transcranial direct current stimulation (6 participants), none showed improvement, whereas 5 showed worsening. Thus, multiday cathodal transcranial direct current stimulation reduced symptoms in some children but not to a clinically meaningful extent, whereas anodal transcranial direct current stimulation worsened symptoms. Our results do not support transcranial direct current stimulation as clinically viable for treating childhood dystonia. © The Author(s) 2015.

    There is increasing opportunity and support for occupational therapists to expand their scope of practice in community settings. However, evidence is needed to increase occupational therapists' knowledge, confidence, and capacity with building community participation and adopting community-centered practice roles. The purpose of this study is to improve occupational therapists' understanding of an approach to building community participation, through case study of a network of Canadian food security programs. Qualitative case study was utilized. Data were semistructured interviews, field observations, documents, and online social media. Thematic analysis was used to identify and describe four themes that relate to processes used to build community participation. The four themes were use of multiple methods, good leaders are fundamental, growing participation via social media, and leveraging outcomes. Occupational therapists can utilize an approach for building community participation that incorporates resource mobilization. Challenges of sustainability and social exclusion must be addressed.

    A three-dimensional, primitive-equation model was used to study gravity currents produced by instantaneous releases of a buoyant fluid in a rectangular channel. Without rotation, the gravity current passes through two distinct phases: an initial adjustment phase in which the front speed is constant, and an eventual self-similar phase in which the front speed decreases with time. With rotation, the gravity current is confined to the right-hand wall, forming a coastal jet. The initial front-speed is constant; however, the front speed decreases rapidly due to strong mixing at the horizontal edge of the gravity current. Also, with rotation, part of the buoyant fluid is trapped near the source region, forming an anticyclonic vortex

    Charged and neutral particle multiplicities of jets associated with identified semileptonic and hadronic b decays are studied. The observed differences between these jets are used to determine the inclusive properties of the weak charged hadronic current. The average charged particle multiplicity of the weak charged hadronic current in b decays is measured for the first time to be 2.69$\\pm$0.07(stat.)$\\pm$0.14(syst.). This result is in good agreement with the JETSET hadronization model of the weak charged hadronic current if 40$\\pm$17\\% of the produced mesons are light--flavored tensor (L=1) mesons. This level of tensor meson production is consistent with the measurement of the $\\pi^0$ multiplicity in the weak charged hadronic current in b decays. \\end{abstract}

  5. Older patients’ participation in team meetings—A phenomenological study from the nurses’ perspective

    ELISABETH Lindberg,

    2013-12-01

    Full Text Available Although the importance of patient participation is acknowledged in today's healthcare, many challenges remain before patient participation can become an integral part of care provision. The ward round has traditionally been the forum for crucial decisions about patient care, but often with limited possibilities for patient participation. As part of the process of improving patient participation, the round in the present study has been replaced by a team meeting (TM to which the patient has been invited. The aim of this study is to highlight nurses’ experiences of older patients’ participation in TMs. The research process was guided by the principles of phenomenological reflective life world research. Data were collected in a Swedish hospital, in a ward specializing in older patients. Nine nurses, who had invited and planned for a patient to participate in TMs and/or had experienced TMs in which patients participated, were interviewed. The essential meaning of patient participation in the TM, as experienced by the nurses, is that patient participation can be supported by a safe relationship in which the patient can make his or her voice heard. Participation is challenged by the patients’ vulnerability and by the subordinated role assigned to the patient. The essential meaning is further described by its constituents: “the need for a guide,” “patient participation challenged by structures,” and “creating space for the whole human being.” In conclusion, the nurse plays a core role in guiding the patient in an unfamiliar situation. The meaning of patient participation in the TM needs to be discussed by professionals so that the patient perspective is present.

    Highlights: • Unique square pancake coil was manufactured. • Measurements in relatively high magnetic field were performed. • Different sections of the coil were characterized. • Parts of the coil which are limiting critical current were identified. - Abstract: Nowadays, superconducting high field magnets are used in numerous applications due to their superior properties. High temperature superconductors (HTS) are usually used for production of circular pancake or racetrack coils. However different geometries of HTS coils might be required for some specific applications. In this study, the HTS coil wound on a rectangular frame was fully characterized in homogeneous DC background field. The study contains measurements of critical current angular dependencies. The critical current of the entire coil and two selected strands under different magnitudes and orientations of external magnetic fields are measured. The critical regions of the coil in different angular regimes are determined. This study brings better understanding of the in- field performance of HTS coils wound on frames with right-angles.

    Retrospective observational study. To investigate the study participation rate of patients with acute spinal cord injury (SCI) early during rehabilitation after conveying preliminary study information. Single SCI rehabilitation center in Switzerland. Newly admitted acute SCI patients receive a flyer to inform them concerning the purpose of clinical research, patient rights and active studies. Upon patient request, detailed study information is given. The rate of patients asking for detailed information (study interest) and the rate of study participation was evaluated from May 2013 to October 2014. Furthermore, the number of patients not withdrawing consent to the utilization of coded health-related data was determined. The flyer was given to 144 of the 183 patients admitted during the observation period. A total of 96 patients (67%) were interested in receiving detailed information, and 71 patients (49%) finally participated in at least one study. The vast majority of patients (that is, 91%) did not withdraw consent for retrospective data analysis. An age over 60 years had a significantly (P⩽0.023) negative effect on study interest and participation, and the consent rate to retrospective data analysis was significantly (Pinterest and participation were reduced more than 5 and 14-fold, respectively, in patients older than 60 years. The relatively low (approximately 50%) study participation rates of acute SCI patients should be considered when planning clinical trials. The recruitment of patients older than 60 years may be reduced substantially.

    Many proponents of gas pipeline studies using the public roadway for their facilities have trouble encouraging public participation. Problems resulting from a lack of public involvement are documented. A public participation process designed to gather meaningful public input is presented through a case study of a public roadway pipeline study in southern Ontario. Techniques are outlined to effectively stimulate public interest and document the public involvement process. Recommendations are made as to the transferability of this process to other jurisdictions.

    The Uranium Epidemiology Study at the University of New Mexico was initiated in 1977 with the objective of assessing health effects of uranium mining in the Grants, New Mexico, area. The planned approach was a cohort study of mortality that would capitalize on the availability of health records at the Grants Clinic. The first year's work confirmed the study's feasibility (Buechley, 1979). Subsequent efforts have focused on the health and exposure data base and comprehensive follow-up. A retrospective cohort study of early miners is in progress; a prospective cohort study of miners who began working under the current federal standard is planned. This report will summarize the current status of the Uranium Epidemiology Study

  10. Patients' Perceptions of Nurses' Behaviour That Influence Patient Participation in Nursing Care: A Critical Incident Study

    Full Text Available Patient participation is an important basis for nursing care and medical treatment and is a legal right in many Western countries. Studies have established that patients consider participation to be both obvious and important, but there are also findings showing the opposite and patients often prefer a passive recipient role. Knowledge of what may influence patients' participation is thus of great importance. The aim was to identify incidents and nurses' behaviours that influence patients' participation in nursing care based on patients' experiences from inpatient somatic care. The Critical Incident Technique (CIT was employed. Interviews were performed with patients (=17, recruited from somatic inpatient care at an internal medical clinic in West Sweden. This study provided a picture of incidents, nurses' behaviours that stimulate or inhibit patients' participation, and patient reactions on nurses' behaviours. Incidents took place during medical ward round, nursing ward round, information session, nursing documentation, drug administration, and meal.

    Patient participation is an important issue in contemporary healthcare as it improves quality of care and enhances positive health outcomes. The participation of patients is mainly initiated by the nurses' willingness to share their power and responsibility, but knowledge on nurses' demographic characteristics influencing this behavior is nonexistent. This knowledge is essential to understand and improve patient participation. To determine if nurses' demographic characteristics influence their willingness to engage in patient participation. A cross-sectional multicenter study in 22 general and three university hospitals with 997 nurses was performed. The Patient Participation Culture Tool for healthcare workers, which measures patient participation behavior, was used. Multilevel analysis, taking into account the difference in wards and hospitals, was used to identify the influence of demographic characteristics. A position as supervisor (range: p nurses seem to be more reluctant in accepting a collaborative patient role (p = .002) and coping with more active patient behavior (p nurses on geriatric wards (p = .013), who also showed less sharing of information with their patients (p nurses' willingness to share power and responsibility with their patients, perhaps indicating that patient participation behavior is an advanced nursing skill and multifaceted interventions, are needed for optimal implementation. Moreover, supervising nurses have different perceptions on patient participation and possibly regard patient participation as an easier task than their team members. This could lead to misunderstandings about the expectations toward patient participation in daily practice, leading to struggles with their nursing staff. Both findings implicate that implementing patient participation on a wide scale is more difficult than expected, which is conflicting with the widespread societal demand for more participation. © 2017 Sigma Theta Tau International.

    In 2001, the National Institute for Health Research Cancer Research Network (NCRN) was established, leading to a rapid increase in clinical research activity across the English NHS. Using colorectal cancer (CRC) as an example, we test the hypothesis that high, sustained hospital-level participation in interventional clinical trials improves outcomes for all patients with CRC managed in those research-intensive hospitals. Data for patients diagnosed with CRC in England in 2001-2008 (n=209 968) were linked with data on accrual to NCRN CRC studies (n=30 998). Hospital Trusts were categorised by the proportion of patients accrued to interventional studies annually. Multivariable models investigated the relationship between 30-day postoperative mortality and 5-year survival and the level and duration of study participation. Most of the Trusts achieving high participation were district general hospitals and the effects were not limited to cancer 'centres of excellence', although such centres do make substantial contributions. Patients treated in Trusts with high research participation (≥16%) in their year of diagnosis had lower postoperative mortality (presearch participation, with a reduction in postoperative mortality of 1.5% (6.5%-5%, pstudies for all patients with CRC treated in the hospital study participants. Improvement precedes and increases with the level and years of sustained participation. Published by the BMJ Publishing Group Limited.

    Individuals with limb absence benefit from participating in sports. While barriers and facilitators affecting sport participation are well documented for adults, they have not been explored for children with limb absence. To identify the perceived factors impacting participation in sports according to children with limb absence and their parents. This study uses a descriptive qualitative study design. Nineteen participants, consisting of children and their parents, were recruited from an outpatient hospital clinic for semi-structured interviews. The 11 interviews were audio recorded and transcribed. Transcripts were then coded and analyzed using the DEPICT model. The thematic analysis was guided by the International Classification of Functioning, Disability, and Health framework. Analysis of our participant interviews identified six themes as having an influence on sport participation: "functionality of prosthesis", "plan in advance", "know what I can do" (understanding capabilities), "it's like every stroke, 2 million questions" (stigma and the social environment), "love for the game" (love for sport), and "these things are an investment" (the investment involved). The findings have the potential to inform the development and implementation of strategies to increase levels of participation in sports among children with limb absence. Information from this study may help to deepen the rehabilitation team's understanding of factors that impact engagement in sports among children with limb absence. Implications for Rehabilitation Children with limb absence present with unique barriers and facilitators to participating in sports, thus, what may be a facilitator or barrier for one child may not for another. Strategies to increase a child's participation in sports should consider both person and environmental factors. Rehabilitation professionals can play a crucial role in educating both families and the community on living and coping with a limb difference, services and

    Recently, staff at Oak Ridge National Laboratory performed a study for the Office of Intergovernmental and Public Accountability within the U.S. Department of Energy's (DOE) Office of Environmental Management (EM), examining how to measure the success of public participation programs. While the study began with a thorough literature review, the primary emphasis of this research effort was on getting key stakeholders to help identify attributes of successful public participation in EM activities and to suggest how those attributes might be measured. Interviews were conducted at nine DOE sites that provided substantial variety in terms of geographic location, types of environmental management activities undertaken, the current life-cycle stage of those EM efforts, and the public participation mechanisms utilized. Approximately 12 to 15 oral interviews were conducted at each site, and each respondent also was asked to complete a written survey. Those interviewed included: non-regulatory state and local government officials; project managers and public participation staff for DOE and its management and operations contractors; non-government groups concerned with environmental protection, public safety, and health issues; federal and state environmental regulators; business organizations; civic groups; and other interested parties. While this study examined only those public participation programs sponsored by DOE, the resulting findings also have applicability to the public involvement efforts sponsored by many other public and private sector organizations

    Although many psychiatric hospital nurses in Bahrain attend at least one continuing nursing education (CNE) activity per year, many others do not. This study explored these nurses' perceptions of CNE and factors that promote or hinder participation in CNE activities. A descriptive design was used to gather data from a convenience sample of 200 nurses working at the psychiatric hospital in Bahrain. Nurses believed that CNE improved the quality of patient care and patient outcomes, increased nurses' knowledge and skills, and kept them current with advances in nursing. Participation in CNE was hindered by unavailability of CNE activities related to psychiatric nursing. The majority of nurses had positive perceptions of CNE. Their participation was hindered by unavailability of CNE activities related to psychiatric nursing. Those responsible for planning continuing education in Bahrain should consider these findings when planning future CNE activities. Copyright 2012, SLACK Incorporated.

    The purpose of this paper was to examine national differences in the desire to participate in decision-making of people with severe mental illness in six European countries. The data was taken from a European longitudinal observational study (CEDAR; ISRCTN75841675). A sample of 514 patients with severe mental illness from the study centers in Ulm, Germany, London, England, Naples, Italy, Debrecen, Hungary, Aalborg, Denmark and Zurich, Switzerland were assessed as to desire to participate in medical decision-making. Associations between desire for participation in decision-making and center location were analyzed with generalized estimating equations. We found large cross-national differences in patients' desire to participate in decision-making, with the center explaining 47.2% of total variance in the desire for participation (Pparticipation, followed by Aalborg (mean=1.97), where scores were in turn significantly higher than in Debrecen (mean=1.56). The lowest scores were reported in Naples (mean=1.14). Over time, the desire for participation in decision-making increased significantly in Zurich (b=0.23) and decreased in Naples (b=-0.14). In all other centers, values remained stable. This study demonstrates that patients' desire for participation in decision-making varies by location. We suggest that more research attention be focused on identifying specific cultural and social factors in each country to further explain observed differences across Europe.

  2. Predictors of Participation of Sophomore Medical Students in a Health-Promoting Intervention: An Observational Study.

    Directory of Open Access Journals (Sweden)

    Thomas Kötter

    Full Text Available Medical students and doctors have to be particularly stress-resilient, as both medical education and practice are considered very stressful. Specific stressors can lead to increased risks of developing, for example, depression, anxiety and burnout. Relaxation techniques have proven to be effective for the prevention of these outcomes in student populations. However, only a very few medical students practice relaxation techniques regularly early on in their studies. Furthermore, it is unclear which students make use of stress-management offers and hence whether vulnerable students are generally reachable. Therefore, the aim of our study was to explore predictors of participating in a voluntary stress management course for sophomore medical students. One cohort of freshmen at a German medical school was surveyed at the end of the freshman year [t1] and at the end of the sophomore year [t2]. In addition to sociodemographic information, we captured perceived study stress, self-rated general health and mental health and dimensions of study-related behaviour and experience as potential predictors of participation at t1. During the sophomore year, we offered the participants a progressive muscle relaxation (PMR beginners' course. At t2, we registered participation status. We used binary logistic regression analyses in order to assess correlations between potential predictors and participation. About one third of the whole class took part in the course. The main reason for non-participation was "no time". Being female and higher levels of anxiety were the strongest predictors of course participation. Career ambition (the higher, the less likely to participate and emotional distancing (the higher, the more likely to participate were further significant predictors. Future interventions should be attractive to both male and female medical students. Ideally, for every hour of stress management teaching, the curriculum should be cut by at least the same

    Children with disability engage in less physical activity compared to their typically developing peers. Our aim was to explore the barriers and facilitators to participation in physical activity for this group. Ten focus groups, involving 63 participants (23 children with disability, 20 parents of children with disability and 20 sport and recreation staff), were held to explore factors perceived as barriers and facilitators to participation in physical activity by children with disability. Data were analysed thematically by two researchers. Four themes were identified: (1) similarities and differences, (2) people make the difference, (3) one size does not fit all, and (4) communication and connections. Key facilitators identified were the need for inclusive pathways that encourage ongoing participation as children grow or as their skills develop, and for better partnerships between key stakeholders from the disability, sport, education and government sectors. Children with disabilities' need for the early attainment of motor and social skills and the integral role of their families in supporting them were considered to influence their participation in physical activity. Children with disability were thought to face additional barriers to participation compared to children with typical development including a lack of instructor skills and unwillingness to be inclusive, negative societal attitudes towards disability, and a lack of local opportunities. The perspectives gathered in this study are relevant to the many stakeholders involved in the design and implementation of effective interventions, strategies and policies to promote participation in physical activity for children with disability. We outline ten strategies for facilitating participation.

We will do that through a double strategy: 1) by critically interrogating the concept of participation (unfolding...... the concept itself), while at the same time, 2) reflecting on the way that participation unfolds across different participatory configurations. We invite researchers and practitioners from PD and HCI and fields in which information technology mediated participation is embedded (e.g. in political studies......, urban planning, participatory arts, business, science and technology studies) to bring a plurality of perspectives and expertise related to participation....

    Background Night shift work and sleep duration have been associated with breast and other cancers. Results from the few prior studies of night shift work and skin cancer risk have been mixed and not fully accounted for other potentially important health-related variables (e.g., sleep characteristics). This study evaluated the relationship between rotating night shift work and skin cancer risk and included additional skin cancer risk factors and sleep-related variables. Methods The current study used data from 74,323 Nurses’ Health Study (NHS) II participants. Cox proportional hazards models were used to estimate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for skin cancers across categories of shift work and sleep duration. Results Over 10 years of follow-up, 4308 BCC, 334 SCC and 212 melanoma cases were identified. Longer duration of rotating night shifts was associated with a linear decline in risk of BCC (HR=0.93, 95% CI: 0.90-0.97 per 5-year increase). Shift work was not significantly associated with either melanoma (HR=1.02, 95% CI: 0.86-1.21) or SCC (HR=0.92, 95% CI: 0.80-1.06). A short sleep duration (≤6 hours per day) was associated with lower risks of melanoma (HR=0.68, 95% CI: 0.46-0.98) and BCC (HR=0.93, 95% CI: 0.86-1.00) compared with the most common report of 7 hours. SCC was not associated with duration of sleep (HR=0.94, 95% CI: 0.83-1.06). Conclusions Longer duration of rotating night shift work and shorter sleep duration were associated with lower risk of some skin cancers. Further research is needed to confirm and identify the mechanisms underlying these associations. PMID:27663986

    The introduction of unrestricted visiting hours has led to the encouragement of parents to stay with and participate in the care of their hospitalised child. In order to stay with the hospitalised child, parents have to be away from home or work, which in turn impacts on their personal and family life. However, no published study on parents' experiences of childcare participation during paediatric hospitalisation has been found for a Chinese population. This study explored Chinese parents' experiences of their participation in taking care of their hospitalised child. A qualitative exploratory design was adopted to capture parents' experiences of participation. The study was conducted in four paediatric wards of a regional acute general hospital in the New Territories, a major geographical region of Hong Kong. Nineteen parents (16 mothers and three fathers) who had a child hospitalised for more than 48 h and identified themselves as staying comparatively longer with the child than their counterpart were recruited. Data were collection by tape-recorded semi-structured interview. Four major categories that illustrated parents' experiences of participation in childcare were identified: reasons for staying with the child, rescheduling of family's routine, expectations of nurses, and comments on facility provisions. The findings highlight parents' desire for participation in caring for their hospitalised child, their unexpressed needs for communication and concern about the non-monetary costs of participation. Most parents viewed accompanying their hospitalised child as an unconditional aspect of being a parent and had a strong desire for participation. Parents' need for communication and emotional support during their participation of childcare in paediatric unit are universal. As Chinese parents are passive in seeking help, nurses should take the initiative in assessing their needs and offering them support accordingly.

    Full Text Available Our work focuses on the participation of students of primary education in decision-making. We carried out a qualitative case study of two public Primary schools with the aim of illustrating good models of student participation. On the one hand, our results highlight the opportunities resulting from the creation of specific structures of student participation, such as class and student councils, because they allow students to participate in collective rule-making, conflict management and the planning and evaluation of school and class activities. On the other hand, the results emphasize the contributions derived from the use of teaching methods that enhance student participation in decision making on academic issues by selecting contents, the inclusion of self-assessment processes and the self-organization of work time. Overall, the results obtained point out that it is feasible to organize the activity of a Primary Education center encouraging students to participate in decision making and they add evidence supported in the practice of two schools to progress in the study and promotion of school participation.

  8. Mexican-American perspectives on participation in clinical trials: A qualitative study

    2016-12-01

    Full Text Available Clinical trials are essential to advancing knowledge to reduce disease morbidity and mortality; however, ethnic and racial minorities remain under-represented in those studies. We explored knowledge and perceptions of clinical trials among Mexican-Americans in Texas. We conducted focus groups (N = 128 stratified by gender, language preference, and geographical location. This paper presents four emergent, primary themes: 1 knowledge and understanding of clinical trials, 2 fears and concerns about participating, 3 perceived benefits of participating, and 4 incentives to participate. Results suggest that lack of knowledge and understanding of clinical trials leads to misunderstanding about research, including fears and lack of trust. Participants indicated that fears related to perceived experimentation, harm, immigration status, and lack of clinical trial opportunities within their communities were barriers to participation. On the other hand, free healthcare access, helping family members in the future, and monetary incentives could facilitate participation. We also found differences across themes by language, gender, and place of residence. Findings from our study could inform the development of interventions to enhance recruitment of Mexican-American participants into clinical trials.

  9. Study on current limiting characteristics of SFCL with two trigger current levels

    Lim, S.H.

    2010-01-01

    In this paper, the superconducting fault current limiter (SFCL) with two trigger current levels was suggested and its effectiveness through the analysis on the current limiting characteristics was described. The proposed SFCL, which consists of the triggering and the limiting components, can limit the fault current by generating the limiting impedance through two steps according to the amplitude of the initial fault current. In case that the fault happens, the lower initial fault current causes the only superconducting element of the triggering component to be quenched. On the other hand, the higher initial fault current makes both the superconducting elements comprising the triggering and the limiting components of the SFCL to be quenched, which contributes to the higher impedance of the SFCL. Therefore, the effective fault current limiting operation of the SFCL can be performed by generating the SFCL's impedance in proportion to the amplitude of the initial fault current. To confirm the current limiting operation of the proposed SFCL, the short-circuit tests of the SFCL according to the fault angle were carried out and its effective fault current limiting operations could be discussed.

    2012-03-01

    currently, assessment of outcomes after joint replacement is predominantly centred on impairment and activity limitation (e.g. walking), with little consideration of participation restriction. structured telephone interviews about participation in leisure activities were conducted with 56 total hip replacement (THR) and 60 total knee replacement (TKR) patients before and 1 year after joint replacement. before surgery, THR patients participated in 209 leisure activities, with an average of four leisure activities per person. TKR patients participated in 171 leisure activities, with an average of three leisure activities per person. The leisure activities were coded into four categories: sports/exercise, hobbies, social activities and holidays. Between 89 and 95% of leisure activities were rated as important by THR and TKR patients prior to surgery. Before surgery, THR patients rated 82% of leisure activities as difficult to perform because of joint problems, which decreased to 25% of leisure activities by 1-year after surgery. TKR patients rated 86% of leisure activities as difficult to perform because of joint problems, which decreased to 32% after surgery. this research highlights that participation in leisure activities is important to patients undergoing joint replacement, but that approximately a quarter of patients are unable to perform their valued leisure activities after surgery.

    The participation data for Adult Health Study examinations conducted in Hiroshima during the period July 1958 to December 31, 1960, are presented. The continuing medical examination program includes approximately 13,700 individuals who form the Adult Health Study population of ABCC in Hiroshima. The Adult Health Study population is composed of four exposure groups of equal size, matched by age and sex. Participation scores are analyzed with respect to exposure, age, sex, and socioeconomic variables as well as history of previous contact with the ABCC programs. Significant differences were demonstrated between the participation scores by age, marital status, history of prior contact with ABCC, and occupation; this latter category was significant only for males. Although differences were observed for these variables, the significance was usually attributable to one category in each of the variables, often the least populated, such as separated or divorced for marital status; and previous history unknown for prior ABCC contact. A trend was apparent with respect to exposure, with the lowest participation noted in the nonexposed and the highest participation in the exposed group with symptoms. Sex differences were not significant. Although relatively minor differences were demonstrated for some variables, the outstanding features of this program are the remarkable high participation scores. Only 9 percent of the population were in the so-called refusal category and over 80 percent of the living Adult Health Study population, including non-Hiroshima residents, were examined during the period considered by this report. 6 references, 1 figure, 9 tables.

    Using the Longitudinal Surveys of Australian Youth (LSAY) data, this paper aimed to examine if, and to what extent, demographic factors predict students' participation in science over the age of 16 (post-16). While all the students participating in this study are attending Australian schools, the comprehensiveness of these datasets, together with inclusion of studies from around the world provides a useful reference point for an international audience. Over 7000 students are included in the analysis of this paper. Characteristics of focus in this paper include groups who have been identified as being underrepresented in past studies including Indigenous students, those from lower-socio-economic status (SES) backgrounds, sex differences and immigrants. Among the factors tested, Indigenous status was the strongest negative predictor of post-16 science participation. SES was also a relatively strong predictor of post-16 science participation. Compared to students categorised with an Australian-ancestry, first-generation and foreign-background students were more likely to participate in post-16 science. The findings of this study contribute to existing research on debates about equity and trends in science participation.

    Social media could help nonprofit communities to organize their communication with their members in new and innovative ways. This could contribute to sustaining or improving the participation of members within these communities. Yet little is known of how to measure and understand the offline community effects of social media use. Therefore, the main question of this study is: “How does the use of social media by members of nonprofit communities affect their offline participation?” The Social...

    Three aspects of noninductive current generation are treated: (1) The kinetic problem, i.e., coupling between current-carrying energetic electrons on the one hand, and the electromagnetic wave and thermal particles on the other. (2). The electromagnetic problem, i.e., calculation of the wave structure produced by the antennas. (3) The study of nonthermal radiation and electrical responses. Green's functions are used to solve the kinetic problem. The electron distribution function is calculated. For the electromagnetic problem of wave structure at different wave numbers, the Green's function of the Maxwell equations in an inhomogeneous, anisotropic medium which is spatially and temporally scattered was calculated. Perturbation of propagation by diffusion and conversion was studied. The calculation of nonthermal radiation and of transfer of electromagnetic wave energy into magnetic energy is derived from the two preceding problems. A method to produce fusion power quasi-continuously using two inductively and thermally coupled tokamaks is proposed [fr

    Experiential learning has been suggested as a framework for planning continuing medical education (CME). We aimed to (1) determine participants' learning styles at traditional CME courses and (2) explore associations between learning styles and participant characteristics. Cross-sectional study of all participants (n = 393) at two Mayo Clinic CME courses who completed the Kolb Learning Style Inventory and provided demographic data. A total of 393 participants returned 241 surveys (response rate, 61.3%). Among the 143 participants (36.4%) who supplied complete demographic and Kolb data, Kolb learning styles included diverging (45; 31.5%), assimilating (56; 39.2%), converging (8; 5.6%), and accommodating (34; 23.8%). Associations existed between learning style and gender (p = 0.02). For most men, learning styles were diverging (23 of 63; 36.5%) and assimilating (30 of 63; 47.6%); for most women, diverging (22 of 80; 27.5%), assimilating (26 of 80; 32.5%), and accommodating (26 of 80; 32.5%). Internal medicine and psychiatry CME participants had diverse learning styles. Female participants had more variation in their learning styles than men. Teaching techniques must vary to appeal to all learners. The experiential learning theory sequentially moves a learner from Why? to What? to How? to If? to accommodate learning styles.

    The pulsed current cathodic protection (PCCP) is a new cathodic protection (CP) technology and shows more advantages over the conventional DC cathodic protection (DCCP) in oil well casing system. However, little information about PCCP is reported. In this research, a simulated CP system was set up in a pool of 3.5 m x 2.0 m x 3.0 m size, in which the effects of the square wave pulsed current (SWPC) parameters (amplitude: IA, frequency: f, duty cycle: P), auxiliary anode distance (d) and media conductivity ({mu}) on the cathodic potential (E) distribution were studied, and the protection effects of PCCP and DCCP were compared. The results show that with increase of the square wave parameters (IA, f, P), the E distribution becomes more negative and the effects of each current parameter are relate closely to the cathode polarizing state. Only with suitable square wave parameters can the whole cathode be effectively protected. With increase of d and {mu}, the E distribution becomes more uniform. Compared with DCCP system, PCCP system has much more uniform E distribution, costs less average current, and gains much better protection effects. Further, the mechanism of PCCP was analyzed.

    The present study aimed to reflect the current situation of social participation in rural areas of China, willingness to participate in social activities, association between health-related quality of life and social participation, and factors related to social participation. A total of 2644 rural adults aged 60 years and older were randomly selected and surveyed with a self-rating questionnaire. We used the unified definition of social participation in our study. The Medical Outcomes Study Short-Form Health Survey was used to measure health-related quality of life. The overall engagement of social activities was 26%. Those who participated in social activities were more likely to have high scores of health-related quality of life. Older men with a high educational level (OR 1.59, 95% CI 1.01-2.29) living alone or with a spouse (OR 1.51, 95% CI 1.08-2.12), high objective social support (OR 1.08, 95% CI 1.00-1.17) and high support utilization (OR 1.13, 95% CI 1.07-1.21) were inclined to engage in social participation. Older women with high individual income (OR 1.74, 95% CI 1.25-2.43), single marital status (OR 1.53, 95% CI 1.11-2.10), normal weight (OR 1.92, 95% CI 1.10-3.34), overweight (OR 2.28, 95% CI 1.24-4.19), living alone or with a spouse (OR 1.55, 95% CI 1.20-2.00), objective social support (OR 1.11, 95% CI 1.04-1.18) and subjective social support (OR 1.15, 95% CI 1.10-1.20) were more willing to engage in social participation. Engagement in social activities is relatively low in rural areas, and associations of willingness and health-related quality of life with social participation were found. Policy-makers and government workers should make appropriate types of encouragement policies around social participation for older adults in rural areas.

    To explore healthcare professionals' perceptions of what patient participation means in a paediatric care context . A qualitative explorative design with grounded theory. Fifteen healthcare professionals who worked in paediatric care settings were either interviewed or asked open-ended questions in a survey, during December 2015-May 2016. Grounded theory was used as a method. The study results provide a theoretical conceptualization of what patient participation meant for healthcare professionals in paediatric care and how participation was enabled. The core category "participation a prerequisite for care" emerged as the main finding explaining the concept as ethical, practical and integrated in the care givers way of working. However, the concept was implicit in the organization. Four additional categories illustrated the healthcare professionals' different strategies used to enhance patient participation; "meeting each child where the child is," "building a relationship with the child," "showing respect for each individual child" and "making the most of the moment."

    Our aim was to assess whether a novel approach of digitally facilitated, citizen-science research, as followed by the Swiss Multiple Sclerosis Registry (Swiss MS Registry), leads to accelerated participant recruitment and more diverse study populations compared with traditional research studies where participants are mostly recruited in study centres without the use of digital technology. The Swiss MS Registry is a prospective, longitudinal, observational study covering all Switzerland. Participants actively contribute to the Swiss MS Registry, from defining research questions to providing data (online or on a paper form) and co-authoring papers. We compared the recruitment dynamics over the first 18 months with the a priori defined recruitment goals and assessed whether a priori defined groups were enrolled who are likely to be missed by traditional research studies. The goal to recruit 400 participants in the first year was reached after only 20 days, and by the end of 18 months 1700 participants had enrolled in the Swiss MS Registry, vastly exceeding expectations. Of the a priori defined groups with potential underrepresentation in other studies, 645 participants (46.5%) received care at a private neurology practice, 167 participants (12%) did not report any use of healthcare services in the past 12 months, 32 (2.3%) participants lived in rural mountainous areas, and 20 (2.0% of the 1041 for whom this information was available) lived in a long-term care facility. Having both online and paper options increased diversity of the study population in terms of geographic origin and type and severity of disease, as well as use of health care services. In particular, paper enrolees tended to be older, more frequently affected by progressive MS types and more likely to have accessed healthcare services in the past 12 months. Academic and industry-driven medical research faces substantial challenges in terms of patient involvement, recruitment, relevance and

    We examined efforts to engage marginalized populations in Ontario Community Health Centers (CHCs), which are primary health care organizations serving 74 high-risk communities. Qualitative case studies of community participation in four Ontario CHCs were carried out through key informant interviews with CHC staff to identify: (i) the approaches, strategies and methods used in participation initiatives aimed specifically at engaging marginalized populations in the planning of and decision making for health services; and (ii) the challenges and enablers for engaging these populations. The marginalized populations involved in the community participation initiatives studied included Low-German Speaking Mennonites in a rural town, newcomer immigrants and refugees in an urban downtown city, immigrant and francophone seniors in an inner city and refugee women in an inner city. Our analysis revealed that enabling the participation of marginalized populations requires CHCs to attend to the barriers experienced by marginalized populations that constrain their participation. Key informants outlined the features of a 'community development approach' that they rely on to address the barriers to marginalized peoples' involvement by strengthening their skills, abilities and leadership in capacity-building activities. The community development approach also shaped the participation methods that were used in the engagement process of CHCs. However, key informants also described the challenges of applying this approach, influenced by the cultural values of some groups, which shaped their willingness and motivation to participate. This study provides further insight into the approach, strategies and methods used in the engagement process to enable the participation of marginalized populations, which may be transferable to other health services settings. © The Author 2016.

    Knowledge of the fetal effects of maternal medication use in pregnancy is often inadequate and current pregnancy pharmacovigilance (PV) surveillance methods have important limitations. Patient self-reporting may be able to mitigate some of these limitations, providing an adequately sized study sample can be recruited. To compare the ability and cost-effectiveness of several direct-to-participant advertising methods for the recruitment of pregnant participants into a study of self-reported gestational exposures and pregnancy outcomes. The Pharmacoepidemiological Research on Outcomes of Therapeutics by a European Consortium (PROTECT) pregnancy study is a non-interventional, prospective pilot study of self-reported medication use and obstetric outcomes provided by a cohort of pregnant women that was conducted in Denmark, the Netherlands, Poland, and the United Kingdom. Direct-to-participant advertisements were provided via websites, emails, leaflets, television, and social media platforms. Over a 70-week recruitment period direct-to-participant advertisements engaged 43,234 individuals with the study website or telephone system; 4.78% (2065/43,234) of which were successfully enrolled and provided study data. Of these 90.4% (1867/2065) were recruited via paid advertising methods, 23.0% (475/2065) of whom were in the first trimester of pregnancy. The overall costs per active recruited participant were lowest for email (€23.24) and website (€24.41) advertisements and highest for leaflet (€83.14) and television (€100.89). Website adverts were substantially superior in their ability to recruit participants during their first trimester of pregnancy (317/668, 47.5%) in comparison with other advertising methods (Padvertisement methods used and in their ability to recruit participants in early pregnancy. Recruitment of a pregnant cohort using direct-to-participant advertisement methods is feasible, but the total costs incurred are not insubstantial. Future research is

    Most researchers support the notion that a direct negative relationship exists between married women's labor force participation and fertility behavior, yet female employment shows no consistent, general relationship with declining fertility at individual and societal levels. Specific conditions under which employment lowers fertility are therefore explored for the case of Bangladesh. The economic, sociological, and world-system theoretical approaches to the relationship and empirical studies in developing countries including Bangladesh are reviewed. 1975-76 Bangladesh Fertility Survey data on births, deaths, nuptiality, and family planning knowledge and practice for 5772 currently married women of 6513 ever married women under 50 sampled are subjected to multivariate analysis for the study. Analysis revealed that women's modern and traditional occupation as well as higher and secondary education significantly lower their fertility, and that higher age, Islamic religion, use of modern contraceptives, and husband's occupation in transitional and modern sectors have significant positive effects on fertility. The correlation between higher fertility and contraceptive use may be due to women's delay in practicing family planning until reaching desired parity and/or high infant mortality driving women to cease practice in order to replace lost offspring. Future research should be conducted with larger samples and also consider occupations of both husbands and wives. Societal attitudes about women's education should be reformed in support of opening rural schools for women. With 90% of women residing in rural areas and women with traditional occupations having lower fertility, more traditional sector opportunities for women in cottage industry and agriculture production are also recommended, and would help balance skewed urban growth and hypertrophication of the tertiary sector. Finally, motivational efforts should be focused upon encouraging younger instead of older

    Maintaining contact with and collecting outcome data from adolescent study participants can present a significant challenge for researchers conducting longitudinal studies. Establishing an organized and effective protocol for participant follow-up is crucial to reduce attrition and maintain high retention rates. This paper describes our methods in using and adapting the evidence-based Engagement, Verification, Maintenance, and Confirmation (EVMC) model to follow up with adolescents 6 and 12 months after implementation of a health program. It extends previous research by focusing on two key modifications to the model: (1) the central role of cell phones and texting to maintain contact with study participants throughout the EVMC process and, (2) use of responsive two-way communication between staff and participants and flexible administration modes and methods in the confirmation phase to ensure that busy teens not only respond to contacts, but also complete data collection. These strategies have resulted in high overall retention rates (87-91%) with adolescent study participants at each follow-up data collection point without the utilization of other, more involved tracking measures. The methods and findings presented may be valuable for other researchers with limited resources planning for or engaged in collecting follow-up outcome data from adolescents enrolled in longitudinal studies.

    Influenza infection can cause severe pneumonia, which is sometimes fatal, particularly in older adults. Influenza results in 3-5 million cases of severe illness and about 250 000 to 500 000 deaths annually worldwide. Social participation in the context of influenza infection is controversial because, although social participation is beneficial in maintaining physical function and mental health, it also increases the risk of contact with infected people. This study examined the association between social participation and influenza infection in Japanese adults aged 65 years or older. Cross-sectional study. Japanese functionally independent adults aged 65 years or older. Among the respondents to the Japan Gerontological Evaluation Study (JAGES) 2013 survey, which took place during the period from October to December 2013, 12 231 men and 14 091 women responded to questions on influenza vaccination and influenza infection. Using JAGES data for 12 231 men and 14 091 women aged ≥65 years, we examined the association between social participation and influenza infection. The association between influenza infection and number of groups in which respondents participated was investigated among adults aged≥65 years, stratified by vaccination status and sex. Unvaccinated women who participated in two or more social activities were 2.20 times (95% CI 1.47 to 3.29) as likely to report an influenza infection as those who reported no social participation. In contrast, vaccinated women who participated in two or more social groups had no additional risk of influenza infection as compared with female elders with no social participation. Among men, participation in social activities was not significantly associated with influenza infection, regardless of vaccination status. Social participation was associated with a higher risk of influenza infection among unvaccinated older women, which suggests a need for further efforts to promote influenza vaccination

Semi-structured interviews were conducted with twenty-nine gay and bisexual men in Scotland who had participated in a bar-based survey. Thematic analysis of men's accounts of their motives for participation and their perceptions of not receiving individual feedback on HIV status suggested a shared understanding of participation in research as a means of contributing to 'community' efforts to prevent the spread of HIV. Most men expressed sophisticated understandings of the purpose of behavioural research and distinguished between this and individual diagnostic testing. Despite calls for feedback on HIV results broadly, for these men feedback on HIV status was not deemed crucial.

    2004-01-01

    Although community participation is seen as central to the practice of health impact assessment (HIA), effective engagement of local people is notoriously difficult to achieve and risks being tokenistic. This qualitative study, set in a deprived estate in northwest England, examined how community participation in the proposed HIA of a Regeneration Masterplan would be affected by the attitudes and experiences of key stakeholders. In-depth interviews were conducted with 12 stakeholders drawn from officials, representatives and local residents linked to the regeneration programme. The results suggest that there may be a large gap between professional rhetoric and the reality of community participation, and that barriers to community participation in HIA may be substantial and institutionalised. If these barriers are to be overcome, it is essential to acknowledge the existence of this rhetoric-reality gap and to address the training and resource needs of both professionals and community members

    Full Text Available Social studies teachers employ discussions about controversial issues in their classrooms as an effective instructional tool in order to improve citizenship education. Therefore, teaching about controversial issues in preservice social studies programs is important for improving pre-service teachers’ understanding of their own abilities to teach about citizenship issues and their skills to teach about controversial issues in their classrooms as well. Preservice teachers ought to be encouraged to participate more in classroom discussions about controversial issues. Therefore, this study aim to understand and explain factors that affect social studies teacher candidates’ participation in classroom discussions about controversial issues and suggest how this process might be more efficient and effective in Turkey. 1957 pre-service social studies teachers from 12 different universities in Turkey participated in this study. A questionaire was used to collect data for this research. The questionaire included likert type 16 items regarding students’ personal information and factors that affect the level of participation in classroom discussions about controversial issues and one open-ended question regarding implications on how discussions can be improved in a way that help the discussions more effective and efficient. Chi-Square, frequency, and percentange tests were used to analyze the quantitative data. Inductive content analysis method was employed to analyze and code the qualitative data. The findings of the study showed that while 92.2 % pre-service social studies teachers stated that they participate in the dicussions on controversial issues when they only find it interested, 79.4 % participant pointed out that they do not participate in the discussions, if they believe they do not have enough knowledge about the topic of the dicussion. In addition, 47.5% of the participants stated that they do not want to participate in the discussions

      Both the Council for International Organization of Medical Sciences and the Helsinki Declaration emphasize that the potential benefits of research should outweigh potential harms; consequently, some work has been conducted on participants' perception of benefits in therapeutic research. However, there appears to be very little work conducted with participants who have joined non-therapeutic research. This work was done to evaluate participants' perception of benefits in a genetic epidemiological study by examining their perception of the potential benefits of enrollment.   In-depth interviews lasting between 45 and 60 minutes were conducted with a convenient sample of 25 ill patients and 25 healthy accompanying relatives enrolled in a genetic epidemiological study of tuberculosis. Recorded interviews were transcribed and analyzed using content analysis.   Participants perceived that research was beneficial and some of the benefits included the generation of new knowledge, finding the cause of diseases, as well as the control, eradication and prevention of disease. Some thought that research was risky whilst others thought that the benefits outweighed the risks.   Participants perceived research to be beneficial and most of them thought that, though it was risky, the benefits outweighed the risks. It is our view that researchers need to give serious consideration to participant's perception of benefits in designing their consent forms, to see to the fulfillment of achievable goals. © 2011 Blackwell Publishing Ltd.

    Social and economic conditions are powerful determinants of women's health status. Microcredit, which involves the provision of small loans to low-income women in the hopes of improving their living conditions, is an increasingly popular intervention to improve women's socioeconomic status. Studies examining the health effects of microcredit programs have had mixed results. We conduct a cross-sectional study among female clients of a non-profit microcredit program in Peru (N = 1,593). The predictor variable is length of microcredit participation. We conduct bivariate and multivariate linear regressions to examine the associations between length of microcredit participation and a variety of measures of women's health. We control for participants' sociodemographic characteristics. We find that longer participation is associated with decreased depressive symptoms, increased social support, and increased perceived control, but these differences are attenuated with the inclusion of covariates. We find no association between length of participation and contraception use, cancer screening, or self-reported days sick. These results demonstrate a positive association between length of microcredit participation and measures of women's psychological health, but not physical health. These findings contribute to the discussion on the potential of microcredit programs to address the socioeconomic determinants of health, and suggest that addressing socioeconomic status may be a key way to improve women's health worldwide.

    Chronically homeless individuals have high rates of hospitalization and death, and they may benefit from the completion of advance directives. To determine the rate of advance directive completion using a counselor-guided intervention, identify characteristics associated with advance directive completion, and describe end-of-life care preferences in a group of chronically homeless individuals. Participants completed a survey and were offered an opportunity to complete an advance directive with a trained counselor. A total of 205 residents of a shelter in Canada for homeless men (89.1% of those approached) participated from April to June 2013. Duration of homelessness was ⩾12 months in 72.8% of participants, and 103 participants (50.2%) chose to complete an advance directive. Socio-demographic characteristics, health status, and health care use were not associated with completion of an advance directive. Participants were more likely to complete an advance directive if they reported thinking about death on a daily basis, believed that thinking about their friends and family was important, or reported knowing their wishes for end-of-life care but not having told anyone about these wishes. Among individuals who completed an advance directive, 61.2% named a substitute decision maker, and 94.1% expressed a preference to receive cardiopulmonary resuscitation in the event of a cardiorespiratory arrest if there was a chance of returning to their current state of health. A counselor-guided intervention can achieve a high rate of advance directive completion among chronically homeless persons. Most participants expressed a preference to receive cardiopulmonary resuscitation in the event of a cardiorespiratory arrest. © The Author(s) 2015.

    A study of mortality, by cause of death, was done on a cohort of 46,186 participants in one or more of five test series. The series studied were UPSHOT-KNOTHOLE (1953) and PLUMBBOB (1957) at the Nevada Test Site, and GREENHOUSE (1951), CASTLE (1954), and REDWING (1956) which were conducted at the Pacific Proving Ground at Enewetak and Bikini. The participants were traced individually by the use of Veterans Administration records. For the participants in each series, the number of deaths attributed to particular causes was compared with the number expected to occur at US cause- and age-specific mortality rates. A total of 5113 deaths from all causes was ascertained; this was 11.1% of the number of participants. The number was, however, only 83.5% of the number expected at US mortality rates. Mortality from leukemia among the 3554 participants at SMOKY - 10 deaths below age 85 - were 2.5 times the expected number. When the leukemia deaths are compared to other deaths in all six data sets, the differences among the series are not significant. No cancer other than leukemia was ascertained to have occurred in significant excess among SMOKY participants and the number of deaths from other cancers (67) was less than the number expected at population rates (83.8). The total body of evidence cannot convincingly either affirm or deny that the higher than statistically expected incidence of leukemia among SMOKY participants (or of prostate cancer among REDWING participants) is the result of radiation exposure incident to the tests. 19 refs., 27 tabs

    To determine whether high school athletic participation among adolescents in Western New York was associated with reduced rates of sexual behavior and pregnancy involvement. A secondary analysis of data from the Family and Adolescent Study, a longitudinal study of a random sample of adolescents (ages 13-16 years) from 699 families living in households in Western New York. A general population sample was obtained with characteristics closely matching the census distributions in the area. Interview and survey methods provided data on athletic participation, frequency of sexual relations during the past year, and risk for pregnancy. Bivariate correlations were used to examine relationships among athletic participation, demographic and control variables, and measures of sexual behavior and pregnancy rates. Next, path analyses were done in order to test for hypothesized relationships between athletic participation, sexual behavior, and pregnancy involvement while controlling for age, race, income, family cohesion, and non-athletic forms of extracurricular activity. Variables that were significantly associated with sexual behavior and/or pregnancy involvement were presented for both sexes within the resulting multivariate models. Lower income and higher rates of sexual activity were associated with higher rates of pregnancy involvement for both sexes. Family cohesion was associated with lower sexual activity rates for both sexes. For girls, athletic participation was directly related to reduced frequency of sexual behavior and, indirectly, to pregnancy risk. Male athletes did not exhibit lower rates of sexual behavior and involvement with pregnancy than male non-athletes. Boys who participated in the arts, however, did report lower rates of sexual behavior and, indirectly, less involvement with pregnancy. Female adolescents who participated in sports were less likely than their non-athletic peers to engage in sexual activity and/or report a pregnancy. Among male

    Current reform documents in education call for elementary and high school students to engage in "authentic" scientific practices. In the past several years a number of authors have suggested that science education research and curriculum development could benefit from insights gained by research in the social studies of science that documents and theorizes science as it is actually done. Yet, although practices of laboratory science are well understood and provide a foundation from which educational practices could be drawn, little is known about the practices of the science disciplines which deal with field research and how people are enculturated into those practices. This dissertation is constituted by a series of research papers on different (although inter-related) topics, in which I examine the enculturation into the practices of field ecology and the world-view that is associated with that enculturation. To better understand the practices of field ecology and how they develop, I conducted several projects: (i) a video ethnography of a second-year university ecology class and observations on research experiences undergraduates experience; (ii) ethnographic research with ecologists conducting field research; (iii) observations of graduate student and professional ecologists as they participated in conferences, engaged in interaction in their laboratory and social settings, and presented/discussed their findings in various settings; (iv) interviews with graduate student and professional ecologists discussing their field research experiences; (v) videotaped interviews with practicing researchers and under/graduate science and non-science students as they interpreted various ecology-related inscriptions; (vi) an analysis of the inscriptions and textual information present in the various texts (textbooks and journals) used to teach students about ecology; and, (vii) observations of elementary school students engaged in practices congruent with those of field

    Many psychological processes unfold over time, necessitating longitudinal research designs. Longitudinal research poses a host of methodological challenges, foremost of which is participant attrition. Building on Dillman's work, we provide a review of how social influence and relationship research informs retention strategies in longitudinal studies. Objective: We introduce the tailored panel management (TPM) approach, which is designed to establish communal norms that increase commitment to a longitudinal study, and this commitment, in turn, increases response rates and buffers against attrition. Specifically, we discuss practices regarding compensation, communication, consistency, and credibility that increase longer term commitment to panel participation. Research design: Throughout the article, we describe how TPM is being used in a national longitudinal study of undergraduate minority science students. TheScienceStudy is a continuing panel, which has 12 waves of data collected across 6 academic years, with response rates ranging from 70% to 92%. Although more than 90% of participants have either left or graduated from their undergraduate degree program, this highly mobile group of people remains engaged in the study. TheScienceStudy has usable longitudinal data from 96% of the original panel. Conclusion: This article combines social psychological theory, current best practice, and a detailed case study to illustrate the TPM approach to longitudinal data collection. The approach provides guidance for other longitudinal researchers, and advocates for empirical research into longitudinal research methodologies. © The Author(s) 2014.

    The purpose of this study was to elicit young people's views on access and participation in cancer research. Eight young people aged 18-25 years with a previous cancer diagnosis aged 15-24 participated in a one day workshop utilising participatory methodology. The workshop consisted of four exercises: role play/scene setting; focus group examining thoughts and opinions of research access and participation; individual reflection on access to different types of research; and creative interpretation of the workshop. Further consultation with 222 young people with cancer was conducted using an electronic survey. Three themes emerged: • Patient choice: Young people thought it was their right to know all options about available research. Without knowledge of all available studies they would be unable to make an informed choice about participation. • Role of healthcare professionals as facilitators/barriers: Young people suggested non-clinical healthcare professionals such as social workers and youth support coordinators may be more suited to approaching young people about participation in psychosocial and health services research. • Value of the research: The what, when and how information was delivered was key in relaying the value of the study and assisting young people in their decision to participate. Further consultation showed approximately 70% wanted to find out about all available research. However, one third trusted healthcare professionals to decide which research studies to inform them of. Effective ways to support healthcare professionals approaching vulnerable populations about research are needed to ensure young people are empowered to make informed choices about research participation.

    The (cost-)effectiveness of a screening programme may be strongly influenced by the participation rate. The objective of this study was to compare participants' and non-participants' motives for the attendance decision as well as their overall preferences for participation in cardiovascular disease screening. This study sampled 1053 participants and 1006 non-participants from a screening trial and randomly allocated the participants to receive different levels of additional information about the screening programme. An ad hoc survey questionnaire about doubt and arguments in relation to the participation decision was given to participants and non-participants along with a contingent valuation task. Among participants, 5% had doubt about participation and the most frequent argument was that they did not want the test result. Among non-participants, 40% would reconsider their non-participation decision after having received additional information while the remainder 60% stood by their decision and provided explicit arguments for it. After having received additional information the participants still valued the programme significantly higher than non-participants, but the difference was relatively small. Participants and non-participants in cardiovascular screening programmes seem to have different strengths of preferences, which signals that their behavioural choice is founded in rational thinking. Furthermore, it appears that additional information and a second reflection about the participation decision may affect a substantial proportion of non-participants to reverse their decision, a finding that should receive policy interest.

    Full Text Available This exploratory study investigates the various factors to be considered when developing and implementing consumer participation in community-based criminal justice settings. The study uses the Victorian Association for the Care and Resettlement of Offenders (VACRO, based in Melbourne, Australia, as its case study site as this organisation is in the process of formally introducing consumer participation. The study is informed by previous research in key areas related to criminal justice, focusing on the perspectives of various stakeholders: staff, volunteers, and consumers. A mixed method approach offered a range of opportunities for participants to engage with the research. Thematic analysis identified multi-layered issues need to be considered when implementing consumer participation. Poor individual understanding was noted as a barrier, alongside a limited shared vision of the concept. These were seen to be influenced by practical issues such as high staff turnover and conceptual challenges, notably the existing discourse around offenders. The implications of these findings for further research on consumer participation in the criminal justice setting are explored.

    In an effort to achieve the objectives, the following scopes were categorized for in-depth study. First of all, a general overview of FNCA, the including background and strategic plans of the forum, structure and activities of the forum, and the FNCA framework was reviewed. Secondly, major activities and implemented achievements in the 7 cooperation projects were also reviewed. Thirdly, the trends and prospects of nuclear power development programs in the participating countries in the FNCA were studied. Finally, proper strategies and recommendations for effective participation in FNCA were presented. This study can be utilized as basic reference material in the efficient implementation of FNCA in the future and for personnel involved in the FNCA affairs as the fundamental elements for implementing FNCA cooperation are presented. Strategies for strengthening Korea's participation in FNCA can be utilized as basic reference for the effective planning and implementation of FNCA activities in the future. Strategies for contributing to promoting nuclear cooperation in the region, for example, cash or in-kind contributions, should be established to effectively participate in the FNCA. It is hoped that this study will be widely utilized for encouraging Korea's participation in the FNCA and for establishing a future direction for FNCA by governments, industries, academic circles and research institutions

    Schools are a key setting for health promotion and improvement activities and the psycho-social environment of the school is an important dimension for promoting the health and well-being of children. The development of Health Promoting Schools (HPS) draws on the settings-based approach to health promotion and includes child participation as one of its basic values. This paper investigates the relationships between child participation, the school environment and child outcomes. Study participants were recruited from nine primary schools, three of which were designated as Health Promoting Schools (HPS). Each HPS was matched with two non-HPS (NHPS) with similar characteristics. Two hundred and thirty-one pupils in the 4th-6th class groups completed self-report questionnaires to document their perspectives on the school socio-ecological environment, how they take part in school life, school processes and their health and well-being. School participation was measured with four scales: participation in school decisions and rules, school activities, school events and positive perception of school participation. The differences in the reported mean score for three of the four scales were marginal and not statistically significant. However, the mean score for reported positive perception of school participation was significantly lower (χ2 = 5.13, df =1, p school decisions and rules (OR 1.22, 95% CI 1.12-1.33), participating in school activities (OR 1.20, 95% CI 1.10-1.31), participating in school events (OR 1.19, 95% CI 1.10-1.29) and reported positive perception of school participation (OR 1.26, 95% CI 1.15-1.39) were all positively associated with health and well-being outcomes for all pupils. Logistic regression analyses indicated positive associations between school participation and school socio-ecological environment. These findings suggest that school participation is important for children in schools and is relevant for improved school environment

    The number of people with multiple chronic conditions increases as a result of ageing. To deal with the complex health-care needs of these patients, it is important that health-care professionals collaborate in interprofessional teams. To deliver patient-centred care, it is often recommended to include the patient as a member of the team. To gain more insight into how health-care professionals and patients, who are used to participate in interprofessional team meetings, experience and organize patient participation in the team meetings. A qualitative study including observations of meetings (n=8), followed by semi-structured interviews with participating health-care professionals (n=8), patients and/or relatives (n=11). Professionals and patients were asked about their experiences of patient participation immediately after the team meetings. Results from both observations and interviews were analysed using content analysis. The findings show a variety of influencing factors related to patient participation that can be divided into five categories: (i) structure and task distribution, (ii) group composition, (iii) relationship between professionals and patients or relatives, (iv) patients' characteristics and (v) the purpose of the meeting. Patient participation during team meetings was appreciated by professionals and patients. A tailored approach to patient involvement during team meetings is preferable. When considering the presence of patients in team meetings, it is recommended to pay attention to patients' willingness and ability to participate, and the necessary information shared before the meeting. Participating patients seem to appreciate support and preparation for the meeting. © 2016 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

    Full Text Available Abstract Background Despite ethical imperatives, informing research participants about the results of the studies in which they take part is not often performed. This is due, in part, to the costs and burdens of communicating with each participant after publication of the results. Methods Following the closeout and publication of a randomized clinical trial of saw palmetto for treatment of symptoms of benign prostatic hyperplasia, patients were invited back to the research center to participate in a group presentation of the study results. Results Approximately 10% of participants attended one of two presentation sessions. Reaction to the experience of the group presentation was very positive among the attendees. Conclusion A group presentation to research participants is an efficient method of communicating study results to those who desire to be informed and was highly valued by those who attended. Prospectively planning for such presentations and greater scheduling flexibility may result in higher attendance rates. Trial Registration Number Clinicaltrials.gov #NCT00037154

    2014-10-01

    This study introduces a comprehensive model to explain patients' prosocial behavioral intentions to participate in clinical training. Using the helping decision model, the authors analyze the combined impact of factors that affect participation intentions. The model includes intrapersonal and interpersonal appraisals triggered by an awareness of the societal need for clinical training as a practical part of medical education. The results of our empirical study (N=317) show that personal costs and anxiety as negative appraisals and a warm glow as a positive appraisal affect participation intentions and fully mediate the effect of the patient's awareness of the societal need. The study results indicate that communication strategies should address patient beliefs about negative personal consequences of participation rather than highlighting the societal need for practical medical education related to clinical training. Based on the results, medical associations could develop guidelines and provide training for physicians on how to motivate patients to participate in clinical training, resulting in more patient-centered standardized consent discussions.

    Directory of Open Access Journals (Sweden)

    Yvonilde Dantas Pinto Medeiros

    2013-03-01

    Full Text Available Traditionally, water resource management has been developed using an essentially technical approach. Currently, public opinion on water resource management is formed as a result of growing environmental concerns and social conflicts arising from poorly planned actions. Environmental problems are complex and have multiple dimensions, including social and economic. Therefore, the inclusion of a human dimension in integrated assessment methodologies is required for the introduction of new elements to the water management planning process. Environmental water allocation (EWA is understood as the quantity, quality and distribution of water required for the maintenance of the functions and processes of aquatic ecosystems on which people depend. Within the various holistic assessment methodologies, the Building Block Methodology (BBM was found to be the most suitable, in the Brazilian context, for maintaining and restoring essential elements of the natural flow regime. This article describes the process of social participation in the environmental flow assessment (EFA for the Sao Francisco River, and compares it with some of the lessons learned from EFA in other parts of the world. The process involved multiple stakeholders who have conflicting interests. BBM was used to guide the field interviews, to incorporate the empirical observations by the local population and to guide the methodological procedures of the multidisciplinary team. The results of the study indicate the effectiveness of this holistic approach in organizing the elements to be evaluated. It also facilitated important contributions to the establishment of a dialogue between the actors to achieve a better understanding of the multiple aspects involved in the decisions associated with the EWA.

    1989-01-01

    The anti-tumor activity of direct current combined with radiation was studied. The experiments were performed with fibrosarcomas (FSA, NFSA) syngenetic to C3H mice. Direct current (0.6mA, 120min) alone was effective to reduce the tumor sizes, but could not cure the tumors. When the direct current therapy (DC therapy) was combined with radiation the DC therapy following radiation was more effective than that before radiation. Using TCD 50 assay, the DC therapy enhanced the effect of a single dose of radiation with the dose-modifying factor of 1.2. However, tumor control rates by the combination therapy were more improved at the smaller doses of radiation than at the larger ones. When the single DC therapy (0.6mA, 120min) was applied immediately after the first radiation of fractionated one the combination therapy still showed the enhanced effect. However, both DC therapy and the radiation therapy were divided in three fractions, and the DC therapy (0.6mA, 40min) was applied after each radiation. Tumor growth retardation by the combination therapy was no different from that by radiation alone. This result suggests that there might be a minimum required dose of coulombs to show the effect of the combination therapy. (author)

  4. Psychosocial work conditions, social participation and social capital: a causal pathway investigated in a longitudinal study.

    Lindström, Martin

    2006-01-01

    Social capital is often claimed to be promoted by stable social structures such as low migration rates between neighbourhoods and social networks that remain stable over time. However, stable social structures may also inhibit the formation of social capital in the form of social networks and social participation. One example is psychosocial conditions at work, which may be determined by characteristics such as demand and control in the work situation. The study examines the active workforce subpopulation within the Swedish Malmö Shoulder Neck Study. A total of 7836 individuals aged 45-69 years, were interviewed at baseline between 1992 and 1994, and at a 1-year follow-up. Four groups of baseline psychosocial work conditions categories defined by the Karasek-Theorell model (jobstrain, passive, active, relaxed) were analysed according to 13 different social participation items during the past year reported at the 1-year follow-up. Odds ratios and 95% confidence intervals with the jobstrain group as a reference were estimated. A multivariate logistic regression model was used to assess differences in different aspects of social participation between the four psychosocial work conditions groups. The results show that the respondents within the active category in particular but also the relaxed category, have significantly higher participation in many of the 13 social participation items, even after multivariate adjustments. The results strongly suggest that psychosocial work conditions may be an important determinant of social capital measured as social participation, a finding of immediate public health relevance because of the well known positive association between social participation and health-related behaviours.

    Health behaviors in youth can predict the same behaviors later in life, but the role of sport participation in predicting healthy lifestyle habits is unclear. This study aimed to investigate the association between participation in organized youth sport and adult healthy lifestyle habits. Data from the longitudinal Cardiovascular Risk in Young Finns Study (YFS) with a 28-year follow-up were used. The participation in sport-club training sessions was self-reported by 9-18-year-olds in 1983 and 1986 (n = 1285). During 2011, participants (aged 37-43-year old) reported their smoking status, alcohol consumption, fruit and vegetable consumption, and physical activity. Odd ratios (OR) were calculated using logistic regression, to examine how participation in organized youth sport was associated with having three or four versus fewer (0-2) healthy habits in adulthood. Participants who were active in youth sport in both 1983 and 1986 had almost two times greater odds of having three or four healthy habits in adulthood than those who were not active at both time points (OR: 1.75, 95%CI: 1.11-2.76). When the analyses were stratified by sex, the findings were statistically significant among women (OR: 2.13, 95%Cl: 1.13-3.99) but not men (OR: 1.27, 95%CI: 0.63-2.58). The results suggest that participation in organized youth sport could promote healthy lifestyle choices. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    An attempt is made to extract information on the nature of light cone current commutators (L. C. C.) in a model independent manner. Using simple assumptions on the validity of the DGS representation for the structure functions of deep inelastic scattering and using the Bjorken--Johnston--Low theorem it is shown that in principle the L. C. C. may be constructed knowing the experimental electron--proton scattering data. On the other hand the scaling behavior of the structure functions is utilized to study the consistency of a vanishing value for various L. C. C. under mild assumptions on the behavior of the DGS spectral moments. (U.S.)

    The Oak Ridge National Laboratory has a comprehensive program concerned with plasma fuel recycle, tritium recovery from blankets, and tritium containment in fusion reactors. Two studies of most current interest are investigations of cryosorption pumping of hydrogen isotopes and measurements of tritium permeation rates through steam generator materials. Cryosorption pumping speeds have been measured for hydrogen, deuterium, and helium at pressures from 10 -8 torr to 3 x 10 -3 torr. Permeation rates through Incoloy 800 have been shown to be drastically reduced when the low pressure side of permeation tubes are exposed to steam. These results will be important considerations in the design of fusion reactor steam generators

    The purpose of this qualitative phenomenological research study was to obtain vivid descriptions of the lived experience of nurses who participated in a student nursing association (SNA) as students. Nursing graduates from five nursing programs in Long Island, New York were identified using a purposive sampling strategy. During individual interviews, the themes of the lived experiences of the participants emerged: (1) leadership: communication, collaboration and resolving conflict, (2) mentoring and mutual support, (3) empowerment and ability to change practice, (4) professionalism, (5) sense of teamwork, and (6) accountability and responsibility. Recommendations from the study included an orientation and mentoring of new students to the SNA by senior students and faculty. Additionally, nursing faculty could integrate SNA activities within the classroom and clinical settings to increase the awareness of the benefits of participation in a student nursing organization. Recommendations for future research include a different sample and use of different research designs.

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

    Patients with Alzheimer's disease frequently elicit neuropsychiatric symptoms as well as cognitive deficits. Above all, depression is one of the most common neuropsychiatric symptoms in Alzheimer's disease but antidepressant drugs have not shown significant beneficial effects on it. Moreover, electroconvulsive therapy has not ensured its safety for potential severe adverse events although it does show beneficial clinical effect. Transcranial direct current stimulation can be the safe alternative of neuromodulation, which applies weak direct electrical current to the brain. Although transcranial direct current stimulation has plausible evidence for its effect on depression in young adult patients, no study has explored it in older subjects with depression in Alzheimer's disease. Therefore, we present a study protocol designed to evaluate the safety and clinical effect of transcranial direct current stimulation on depression in Alzheimer's disease in subjects aged over 65 years. This is a two-arm, parallel-design, randomized controlled trial, in which patients and assessors will be blinded. Subjects will be randomized to either an active or a sham transcranial direct current stimulation group. Participants in both groups will be evaluated at baseline, immediately, and 2 weeks after the intervention. This study investigates the safety and effect of transcranial direct current stimulation that may bring a significant impact on both depression and cognition in patients with Alzheimer's disease, and may be useful to enhance their quality of life.

    The discovery of evolutionarily conserved Atg genes required for autophagy in yeast truly revolutionized this research field and made it possible to carry out functional studies on model organisms. Insects including Drosophila are classical and still popular models to study autophagy, starting from the 1960s. This review aims to summarize past achievements and our current knowledge about the role and regulation of autophagy in Drosophila, with an outlook to yeast and mammals. The basic mechanisms of autophagy in fruit fly cells appear to be quite similar to other eukaryotes, and the role that this lysosomal self-degradation process plays in Drosophila models of various diseases already made it possible to recognize certain aspects of human pathologies. Future studies in this complete animal hold great promise for the better understanding of such processes and may also help finding new research avenues for the treatment of disorders with misregulated autophagy.

    Bronchiectasis is the abnormal, irreversible dilatation of diseased bronchi. Permanently dilated airways, usually in the medium-sized bronchi, are inflamed and often obstructed with thick, purulent secretions. Known causative factors include postinfection bronchial damage, postinhalation injury, hypersensitivity reactions, and congenital airway obstructive disorders. Typical symptoms include sputum overproduction, fever, pleurisy, dyspnea, and chronic cough. Diagnosis involves radiographic studies and pulmonary function testing. Treatment includes oral, aerosolized, or intravenous antibiotic therapy according to the severity of the exacerbation, and mucus clearance by means of bronchial hygiene assistive devices, chest physiotherapy, postural drainage, and high-frequency chest compression. We present a review of bronchiectasis and offer 3 case studies illustrating current management of different presentations, including use of aerosolized antibiotics for patients infected with Pseudomonas aeruginosa. Although an adjunctive program of pulmonary rehabilitation may be useful for patients with bronchiectasis, no confirming studies have been performed to date, and additional research in this area is warranted.

    Night shift work and sleep duration have been associated with breast and other cancers. Results from the few prior studies of night shift work and skin cancer risk have been mixed and not fully accounted for other potentially important health-related variables (eg, sleep characteristics). This study evaluated the relationship between rotating night shift work and skin cancer risk and included additional skin cancer risk factors and sleep-related variables. The current study used data from 74 323 Nurses' Health Study (NHS) II participants. Cox proportional hazards models were used to estimate multivariable-adjusted HRs and 95% CIs for skin cancers across categories of shift work and sleep duration. Over 10 years of follow-up, 4308 basal cell carcinoma (BCC), 334 squamous cell carcinoma (SCC) and 212 melanoma cases were identified. Longer duration of rotating night shifts was associated with a linear decline in risk of BCC (HR=0.93, 95% CI 0.90 to 0.97 per 5-year increase). Shift work was not significantly associated with either melanoma (HR=1.02, 95% CI 0.86 to 1.21) or SCC (HR=0.92, 95% CI 0.80 to 1.06). A short sleep duration (≤6 hours per day) was associated with lower risks of melanoma (HR=0.68, 95% CI 0.46 to 0.98) and BCC (HR=0.93, 95% CI 0.86 to 1.00) compared with the most common report of 7 hours. SCC was not associated with duration of sleep (HR=0.94, 95% CI 0.83 to 1.06). Longer duration of rotating night shift work and shorter sleep duration were associated with lower risk of some skin cancers. Further research is needed to confirm and identify the mechanisms underlying these associations. Published by the BMJ Publishing Group Limited.

    Bangladesh has enthusiastically launched social forestry projects that make grandiose promises of seeking local community involvement and participation in the management of forest resources. This study examines the functioning of the Chandra Agroforestry Research and Demonstration Project to evaluate the actual extent and nature of popular participation it entails. After discussing the project and its locale, the methodology of the study is described as an analysis of qualitative and quantitative data collected in the period February-August 1994. The theoretical framework was based on a modified version of Zaman's framework that uses prevalence and opportunity as the indicators of participation. Analysis of prevalence indicators reveals that professional foresters make all major decisions for the project without consulting the farmers involved. The government also has sole responsibility for monitoring and evaluating the project, and the farmers are skeptical that the government will allow them to profit from the benefits arising from the project. Analysis of opportunity indicators shows that the project is not decentralized, cooperative and collaborative linkages have not been made, project flexibility has been sacrificed to bureaucracy, and the incentives promised to the farmers have not materialized. It is concluded that the participation of local residents in the Chandra project has been insignificant but that the project has succeeded in reducing 1) the historical distrust and conflict between forestry officials and local farmers, 2) encroachment on government lands, and 3) the rate of deforestation. In addition, the project has given participating farmers a sense of security.

  18. Political Regime and Learning Outcomes of Stakeholder Participation: Cross-National Study of 81 Biosphere Reserves

    Full Text Available Stakeholder participation in natural resource management has spread widely, even to nondemocracies, driven by expectations of beneficial outcomes such as multidirectional learning. However, can we expect participation to be equally effective in achieving multidirectional learning in democracies and nondemocracies? Unsurprisingly, previous studies indicate the relevance of power distribution for learning. Higher levels of repression and accumulation of political capital in nondemocracies should limit the distribution of power across stakeholders. Yet, the relationship between political regime, participation, and learning has rarely been studied empirically. I address this gap by analysing multidirectional learning in stakeholder participation in 81 Man and the Biosphere reserves across 35 countries using ordinary least squares regression, Firth logistic regression, and heat maps. The results suggest that the amount of stakeholders sharing knowledge and learning is similar in both regimes. However, a closer analysis reveals differences in the impact different stakeholders have on the learning process. More concretely, local actors share knowledge more often and have a greater impact on stakeholders’ learning in democracies, while state actors display similar behavior across regimes in terms of learning and sharing knowledge. Thus, although there are notable similarities across regimes, multidirectional learning through stakeholder participation is influenced by the political context.

    Individuals on long-term sick leave attending occupational rehabilitation often complain about impairments in cognitive functions such as memory and attention. Knowledge of cognitive functioning in these individuals is limited. Such knowledge is clinically relevant for improving occupational rehabilitation programmes. The aims of this feasibility study were to assess the methodological design and to investigate changes in memory and attention on participants during occupational rehabilitation. Individuals attending occupational rehabilitation (n = 28) and individuals working full time (n = 25) matched for age, gender, and education participated. The two groups were administered cognitive tests targeting memory and attention and self-reported questionnaires at pre-test and post-test. Outcome measures were speed and accuracy of responses on the cognitive tests and self-reported work ability, subjective health complaints, and symptoms of depression and anxiety. In total, 35% of all invited participants agreed to take part and 93% of these also completed the second test. The mean gain scores in the intervention group were significantly higher than in the control group in response latency on simple and choice reaction time and errors in spatial working memory. The results of this study indicate that the motivation of participants to complete testing was high. Improvements in memory and attention were evident in rehabilitation participants indicating that rehabilitation may have an effect on cognitive functions.

    Full Text Available In the present article we carry out a field study in a state school located in Carcaixent (from Valencia about the different perceptions, reflections and impressions of the faculty, management team, Parents Association (AMPA and parents from the political and critical reflection about the active participation of families. Thanks to a set of semi-structured interviews, its transcription and further analysis of its contents, we have obtained valuable conclusions and reflections which indicate the importance that families give to participation, to the point that they are immerse in the process of transformation in a learning community (CdA. Among the conclusions obtained in the mentioned qualitative study, we have been able to observe the familiar perceptions about participation, the existing obstacles and determinants for it, the relationship between the different members of the educational community, the channels of participation, etc.; a whole range of considerations which provide useful information of political and pedagogical character. These considerations can orientate the implementation of school participation policies and the construction of a cohesive and active educational community.

    Many children are not physically active enough for a health benefit. One avenue of physical activity is modified sport programs, designed as an introduction to sport for young children. This longitudinal study identified trends in participation among children aged 4-12 years. Outcomes included continuation in the modified sports program, withdrawal from the program or transition to club sport competition. De-identified data on participant membership registrations in three popular sports in the Australian state of Victoria were obtained from each sport's state governing body over a 4-year period (2009-2012 for Sport A and 2010-2013 for Sports B and C). From the membership registrations, those who were enrolled in a modified sports program in the first year were tracked over the subsequent three years and classified as one of: transition (member transitioned from a modified sport program to a club competition); continue (member continued participation in a modified sport program; or withdraw (member discontinued a modified program and did not transition to club competition). Many modified sports participants were very young, especially males aged 4-6 years. More children withdrew from their modified sport program rather than transitioning. There were age differences between when boys and girls started, withdrew and transitioned from the modified sports programs. If we can retain children in sport it is likely to be beneficial for their health. This study highlights considerations for the development and implementation of sport policies and programming to ensure lifelong participation is encouraged for both males and females.

    Full Text Available Introduction: Farmers are facing with a variety of natural and unnatural risks in agricultural activities, and thus their income is unstable. A wide range of risks such as risks of production, price risk, financial and human risks, influence the income of agricultural products. One of the major risks that farmers faced is the risk of price volatility of agricultural products. Cotton is one of the agricultural products with high real price volatility. Numerous tools for marketing and risk management for agricultural products in the face of price risks are available. Futures and options contracts may be the most important available tools (to reduce price volatility in agricultural products. The purpose of the current study was to look at the possibility of farmers participations in the future and option markets that presented as a means to reduce the cotton prices volatility. The dependent variable for this purpose had four categories and these included: participate in both the market, participation in the future market, participation in the option market and participation in both future and option markets. Materials and Methods: data gathered with interview and completing 200 questionnaires of cotton growers using simple random sampling. Multinomial Logit Regression Model was used for data analysis. Results and Discussion: To measure content validity of the preliminary study the validity of confirmatory factor analysis were used. For calculating reliability, the pre-test done with 30 questionnaires and reliability, coefficient Cronbach alpha was 0.79. The independence of dependent variables categories was confirmed by Hausman test results. The Likelihood ratio and Wald showed these categories are not combinable. Results indicated into period 2014 -2015 and the sample under study, 35% of cotton growers unwilling to participate in future and option markets. Farmers willingness to participate in future and option market was 19% and %21

    Objective The goal of the prospective Adventist Health Study-2 (AHS-2) was to examine the relationship between diet and risk of breast, prostate and colon cancers in Black and White participants. This paper describes the study design, recruitment methods, response rates, and characteristics of Blacks in the AHS-2, thus providing insights about effective strategies to recruit Blacks to participate in research studies. Design We designed a church-based recruitment model and trained local recruiters who used various strategies to recruit participants in their churches. Participants completed a 50-page self-administered dietary and lifestyle questionnaire. Participants Participants are Black Seventh-day Adventists, aged 30–109 years, and members of 1,209 Black churches throughout the United States and Canada. Results Approximately 48,328 Blacks from an estimated target group of over 90,000 signed up for the study and 25,087 completed the questionnaire, comprising about 26% of the larger 97,000 AHS-2-member cohort. Participants were diverse in age, geographic location, education, and income. Seventy percent were female with a median age of 59 years. Conclusion In spite of many recruitment challenges and barriers, we successfully recruited a large cohort whose data should provide some answers as to why Blacks have poorer health outcomes than several other ethnic groups, and help explain existing health disparities.

    Recent reviews quantifying the effects of single sessions of transcranial direct current stimulation (or tDCS) in healthy volunteers find only minor effects on cognition despite the popularity of this technique. Here, we wanted to quantify the effects of tDCS on language production tasks that measure word reading and picture naming. We reviewed 14 papers measuring tDCS effects across a total of 96 conditions to a) quantify effects of conventional stimulation on language regions (i.e., left hemisphere anodal tDCS administered to temporal/frontal areas) under normal conditions or under conditions of cognitive (semantic) interference; b) identify parameters which may moderate the size of the tDCS effect within conventional stimulation protocols (e.g., online vs offline, high vs. low current densities, and short vs. long durations), as well as within types of stimulation not typically explored by previous reviews (i.e., right hemisphere anodal tDCS or left/right hemisphere cathodal tDCS). In all analyses there was no significant effect of tDCS, but we did find a small but significant effect of time and duration of stimulation with stronger effects for offline stimulation and for shorter durations (tDCS and its poor efficacy in healthy participants.

    Are inpatients undergoing rehabilitation who appear able to count exercises able to quantify accurately the amount of exercise they undertake? Observational study. Inpatients in an aged care rehabilitation unit and a neurological rehabilitation unit, who appeared able to count their exercises during a 1-2 min observation by their treating physiotherapist. Participants were observed for 30 min by an external observer while they exercised in the physiotherapy gymnasium. Both the participants and the observer counted exercise repetitions with a hand-held tally counter and the two tallies were compared. Of the 60 people admitted for aged care rehabilitation during the study period, 49 (82%) were judged by their treating therapist to be able to count their own exercise repetitions accurately. Of the 30 people admitted for neurological rehabilitation during the study period, 20 (67%) were judged by their treating therapist to be able to count their repetitions accurately. Of the 69 people judged to be accurate, 40 underwent observation while exercising. There was excellent agreement between these participants' counts of their exercise repetitions and the observers' counts, ICC (3,1) of 0.99 (95% CI 0.98 to 0.99). Eleven participants (28%) were in complete agreement with the observer. A further 19 participants (48%) varied from the observer by less than 10%. Therapists were able to identify a group of rehabilitation participants who were accurate in counting their exercise repetitions. Counting of exercise repetitions by therapist-selected patients is a valid means of quantifying exercise dosage during inpatient rehabilitation. Copyright © 2011 Australian Physiotherapy Association.

    Full Text Available OBJECTIVE: We performed a qualitative study among women within 5 years of Gestational Diabetes (GDM diagnosis. Our aim was to identify the key elements that would enhance participation in a type 2 diabetes (DM2 prevention program. RESEARCH DESIGN AND METHODS: Potential participants received up to three invitation letters from their GDM physician. Four focus groups were held. Discussants were invited to comment on potential facilitators/barriers to participation and were probed on attitudes towards meal replacement and Internet/social media tools. Recurring themes were identified through qualitative content analysis of discussion transcripts. RESULTS: Among the 1,201 contacted and 79 eligible/interested, 29 women attended a focus group discussion. More than half of discussants were overweight/obese, and less than half were physically active. For DM2 prevention, a strong need for social support to achieve changes in dietary and physical activity habits was expressed. In this regard, face-to-face interactions with peers and professionals were preferred, with adjunctive roles for Internet/social media. Further, direct participation of partners/spouses in a DM2 prevention program was viewed as important to enhance support for behavioural change at home. Discussants highlighted work and child-related responsibilities as potential barriers to participation, and emphasized the importance of childcare support to allow attendance. Meal replacements were viewed with little interest, with concerns that their use would provide a poor example of eating behaviour to children. CONCLUSIONS: Among women within 5 years of a GDM diagnosis who participated in a focus group discussion, participation in a DM2 prevention program would be enhanced by face-to-face interactions with professionals and peers, provision of childcare support, and inclusion of spouses/partners.

    We performed a qualitative study among women within 5 years of Gestational Diabetes (GDM) diagnosis. Our aim was to identify the key elements that would enhance participation in a type 2 diabetes (DM2) prevention program. Potential participants received up to three invitation letters from their GDM physician. Four focus groups were held. Discussants were invited to comment on potential facilitators/barriers to participation and were probed on attitudes towards meal replacement and Internet/social media tools. Recurring themes were identified through qualitative content analysis of discussion transcripts. Among the 1,201 contacted and 79 eligible/interested, 29 women attended a focus group discussion. More than half of discussants were overweight/obese, and less than half were physically active. For DM2 prevention, a strong need for social support to achieve changes in dietary and physical activity habits was expressed. In this regard, face-to-face interactions with peers and professionals were preferred, with adjunctive roles for Internet/social media. Further, direct participation of partners/spouses in a DM2 prevention program was viewed as important to enhance support for behavioural change at home. Discussants highlighted work and child-related responsibilities as potential barriers to participation, and emphasized the importance of childcare support to allow attendance. Meal replacements were viewed with little interest, with concerns that their use would provide a poor example of eating behaviour to children. Among women within 5 years of a GDM diagnosis who participated in a focus group discussion, participation in a DM2 prevention program would be enhanced by face-to-face interactions with professionals and peers, provision of childcare support, and inclusion of spouses/partners.

  10. What are the Facilitators and Obstacles to Participation in Workplace Team Sport? A Qualitative Study

    Full Text Available Working age adults are failing to meet physical activity recommendations. Inactive behaviours are increasing costs for diminished individual and organisational health. The workplace is a priority setting to promote physical activity, however there is a lack of evidence about why some employees choose to participate in novel workplace activities, such as team sport, whilst others do not. The aim of this study was to explore the complexity of facilitators and obstacles associated with participation in workplace team sport.Twenty-nine semi-structured face-to-face and telephone interviews were conducted with office workers (58% female (36 ± 7.71 from manufacturing, public services, and educational services. Data was analysed through template analysis.Five sub-level (i.e., intrapersonal, interpersonal, organisational, community and societal influences facilitate participation or create obstacles for participants. Participants were challenged by a lack of competence, self-efficacy, negative sporting ideals and amotivation. Unhealthy competition, an unstable work-life balance and unsupportive colleagues created obstacles to participation. An unsupportive organisation and workplace culture placed demands on workplace champions, funding, facilities and communication. Healthy competitions, high perceptions of competence and self-efficacy, and being motivated autonomously enabled participation. Further, relatedness and social support created a physical activity culture where flexible working was encouraged and team sport was promoted in accessible locations within the organisation. Researchers should consider accounting for complexity of these influences. A participatory approach may tailor interventions to individual organisations and the employees that work within them. Interventions whereby autonomy, competence and relatedness are supported are recommended. This may be achieved by adapting sports and training workplace champions.

    2007-11-01

    Full Text Available Abstract Background Formal checks of participant understanding are now widely recommended to improve informed consent processes. However, the views of the participants these assessments are designed to protect are rarely considered. In this paper the findings of a qualitative study aimed at documenting community reactions to a semi-structured questionnaire ('quiz' are reported. The quiz was administered to 189 mothers after consenting for their children to participate in a malaria vaccine trial on the Kenyan Coast. Methods Once the malaria vaccine trial was underway, focus group discussions were held with some of these mothers (nine groups; 103 mothers, and with community-based field staff attached to the malaria vaccine trial (two groups of five workers. Individual interviews with other trial staff were also held. Results The quiz prompted community members to voice concerns about blood sampling and vaccine side-effects, thereby encouraging additional discussions and interactions between the research team and potential study participants. However, it also caused significant upset and concern. Some of the quiz questions, or the way in which they were asked, appeared to fuel misconceptions and fears, with potentially negative consequences for both the study and community members. Conclusion Formal approaches to checking study understanding should be employed with sensitivity and caution. They are influenced by and impact upon complex social relationships between and among researchers and community members. Adequate consideration of these contexts in assessments of understanding, and in responding to the issues raised, requires strong social science capacity.

  8. Private landowners and environmental conservation: a case study of social-psychological determinants of conservation program participation in Ontario

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available Preservation of biodiversity and continued provision of ecosystem services increasingly relies on environmental conservation on private lands. Despite a multitude of past studies, our knowledge of the motives, opportunities, and challenges of private land conservation, especially on nonworking lands, where financial incentives are less relevant, remains incomplete. A key reason is that a variety of theoretical approaches, resulting in diverging study results, have been used to investigate private land conservation. To help remedy this problem, the current study rigorously examined several established social-psychological determinants of proenvironmental behaviors and developed a comprehensive model, which merged elements from previous studies, to investigate landowner participation in a government-sponsored private land conservation program for nonworking lands. The results are based on analysis of a mailed survey of 800 program-eligible landowners. Contrasting program participants with nonparticipants, we elicited information such as about values, worldviews, socio-demographic characteristics, and property attributes that led landowners to participate in this conservation program. The results of our study illustrate the complex relationships among values, worldviews, norms, attitudes, and behaviors emphasizing the importance of proenvironmental worldviews and of formal education for increasing the likelihood of enrollment in this government-sponsored private land conservation program. Against expectation, neither personal norms, household income, political leaning, nor the size of the eligible property area were found to be important in directly determining the decision to enroll in this conservation program. However, an association of political leaning with stated personal obligation for private land conservation was found. Our results highlight the relationship between formal education and achievement of private land conservation goals

    The labor force participation rate is an important indicator of the state of the labor market and a major input into the economy's potential for creating goods and services. The objectives of this paper are to examine the prevalence of labor force participation among older people in Thailand and to investigate the factors affecting this participation. The data for this study were drawn from the '2007 Survey of Older Persons' in Thailand. Bivariate analysis was used to identify the factors associated with labor force participation. The variables were further examined using multivariate analysis in order to identify the significant predictors of the likelihood of older people participating in the labor force, after controlling for other variables. Overall, 30,427 elderly people aged 60 or above were interviewed. More than a third (35%) of all respondents had participated in the labor force during the seven days preceding the survey. Respondents who were female (OR=0.56), those who were older (OR=0.47 for 70-79 and 0.21 for 80+ years), those who were widowed/divorced (OR=0.85), those who were living with their children (OR=0.69), those whose family income was relatively low, and those who worked in government sectors (OR=0.33) were less likely to participate in the labor force than were their counterparts. On the other hand, those who lived in urban areas (OR=1.2), those who had a low level of education (OR, secondary level 1.8, primary 2.4, and no schooling 2.5), those who were the head of the household (OR=1.9), and those who were in debt (OR=2.3) were more likely be involved in the labor force than their comparison groups. Furthermore, respondents who experienced greater difficulty in daily living, those who suffered from more chronic diseases, and those who assessed their health as poor were less likely to participate in the labor force than their counterparts. Labor force participation in their advanced years is not uncommon among the Thai elderly. The results

  12. The Vulnerability of Study Participants in the Context of Transnational Biomedical Research: From Conceptual Considerations to Practical Implications.

    Orth, Helen Grete; Schicktanz, Silke

    2017-08-01

    Outsourcing clinical trials sponsored by pharmaceutical companies from industrialized countries to low- (middle)-income countries - summarized as transnational biomedical research (TBR) - has lead to many concerns about ethical standards. Whether study participants are particularly vulnerable is one of those concerns. However, the concept of vulnerability is still vague and varies in its definition. Despite the fact that important international ethical guidelines such as the Declaration of Helsinki by the World Medical Association or the Ethical Guidelines for Biomedical Research Involving Human Subjects by the Council of International Organizations of Medical Sciences refer to vulnerability as ethical principle, each of their approaches are different. To overcome these shortcomings, we analyze and unite different approaches of vulnerability and develop practical criteria in order to operationalize the concept especially for the context of TBR. These criteria refer to the context of a study as well as the characteristics and the current living situation of study participants. Based on a case study of an HIV-vaccine-trial conducted in India we demonstrate how those criteria can be applied in a retrospective way to identify potential ethical conflicts. The criteria can also indicate a prospective function for ethical pre-assessment. For this, we provide an outlook for three major topics: 1. Vulnerability as a normative concept: Different ways of protection; 2. The relevance of transparency and 3. Vulnerability as an instrument to increase decision participation of human subjects. © 2016 John Wiley & Sons Ltd.

  13. Current Conceptual Challenges in the Study of Rhythm Processing Deficits

    Directory of Open Access Journals (Sweden)

    Pauline eTranchant

    2015-06-01

    Full Text Available Interest in the study of rhythm processing deficits (RPD is currently growing in the cognitive neuroscience community, as this type of investigation constitutes a powerful tool for the understanding of normal rhythm processing. Because this field is in its infancy, it still lacks a common conceptual vocabulary to facilitate effective communication between different researchers and research groups. In this commentary, we provide a brief review of recent reports of RPD through the lens of one important empirical issue: the method by which beat perception is measured, and the consequences of method selection for the researcher’s ability to specify which mechanisms are impaired in RPD. This critical reading advocates for the importance of matching measurement tools to the putative neurocognitive mechanisms under study, and reveals the need for effective and specific assessments of the different aspects of rhythm perception and synchronization.

    Physical activity has many benefits for older adults, but adherence is often low. The purposes of this study were to (1) identify motivators and barriers for participation in EnhanceFitness (EF), a group-based exercise program; and (2) quantitatively examine the association between motivators, barriers and individual characteristics, and ongoing participation in the program. This was a prospective, cross-sectional study. We mailed a pilot, investigator-developed survey to assess motivators and barriers to exercising to 340 adults who started a new EF class, regardless of their attendance rate. We precoded surveys on the basis of class attendance, with former participants defined as having no attendance a month or more before a 4-month fitness check. Of the 241 respondents (71% response rate), 61 (25%) were precoded as former participants and 180 (75%) as current participants. The mean age of respondents was 71 years and they were predominately female (89%). More than half of respondents were whites (58%), and almost half were married (46%). Former participants reported lower total motivation scores than current participants (P exercise," "Personal illness," and "Exercise caused pain") and 2 motivators ("I want to exercise" and "I plan exercise as part of my day") were significantly different between current and former participants. Discrete event history models show that dropout was related positively to ethnicity (whites were more likely to drop out) and health-related barriers. In newly formed EF classes, participants who drop out report more program, psychosocial, and health barriers, and fewer program and psychosocial motivators. Total barrier score and health barriers significantly predict a participant's dropping out, and white ethnicity is associated with a higher likelihood of dropping out. Employing strategies that address health barriers to participation could improve attendance rates for group-based exercise programs.

    To describe patient participation in decision making during nursing care from patients' and nursing staff' perspectives. The sample consisted of medical and surgical patients (n = 300) and the nursing staff (n = 118) working in the respective wards in three general hospitals. A questionnaire was used for the study; data were collected from April 2009 to September 2010. Data were analyzed by an exploratory factor analysis. Patient participation was recorded at a medium level during nursing care, although it was rated as important from both patients and nursing staff. Exploratory factor analysis revealed the factor structure for the planning and implementation of the nursing care. Providers and receivers of nursing care perceived participation in a similar way. Interpersonal interaction was supported from older and less educated patients, as well as from university-educated nurses. Patient participation was greater in practical aspects of care and limited in technical medical issues and supportive services. Patient participation, although moderate, was evident during nursing care in hospital settings. Paternalism in the decision-making process was the dominant trend, whereas interpersonal interaction between the parties was recognized as a prerequisite for planning nursing care. © 2014 Wiley Periodicals, Inc.

    The article focuses on women snowboarders' networking and relationships with national snowboard associations and commercial organizers. The study was conducted at an International Women Snowboard Camp, which attracted women snowboarders from five different countries. A qualitative interview was undertaken with participants from each country, eight in total, plus an interview with one of the organizers (a woman). The results indicate that participants from the Nordic countries adopt a more proactive stand to promote snowboarding by organizing specific groups in relation to national associations, particularly the Norwegians and the Finnish. Furthermore, some collaboration across national boarders appeared. The only Swedish participant was associated with several snowboarding communities; whereas the Italian (only one) and the Latvian snowboarders had links with commercial organizers, apparently male dominated in structure. The findings are discussed in the light of Castells' network theory and identity construction in social movements, and gender perspectives. The participants' doing/undoing gender reveals different strategies in negotiating hegemonic masculinity and the power structure in the organizations. Narratives from the Nordic participants reflect undoing gender that impacts on identity constructions in terms of project and/or resistance identity. The Italians and Latvians seemingly do gender while undertaking a subordinate position in the male-dominated structure. © 2010 John Wiley & Sons A/S.

    1986-01-01

    Full Text Available After describing types of research designs for the study of community participation in health care programmes, this paper examines one methodology, the quantitative methodology, the quantitative methodology, in detail. It presents some of the major attractions and limitations of this approach. The attractions include the need for evaluation of success and failure and of cost effectiveness of programmes. The limitations include the inability of the approach to deal with definitions and interventions that cannot be quantitified and the difficulty of identifying casual relationship between interventions and outcomes. These characteristics are illustrated by a case by a medical school in Asia. Research design, research developments and research outcomes are described and analysed. The paper concludes that an alternative analysis which examines the linkages between participation and health improvements would be more useful as it would allow the political, social and economic dimensions of community participation to be examined.

    Fast wave electron heating experiment (FWEH) on JFT-2M and JT-60 and analysis of fast wave current drive (FWCD) ability on JT-60U are presented. In the JFT-2M, absorption of fast waves have been investigated by using a phased four-loop antenna array. The absorption of the fast waves has been studied for various plasma parameters by using combination of other additional heating methods such as electron cyclotron heating (ECH) and ion cyclotron heating. It is shown that the absorption efficiency estimated from various methods well correlates with one calculated theoretically in single pass damping. Interaction of the fast waves with fast electrons in combination with ECH has been examined through the measurement of non-thermal electron cyclotron emission (ECE). The observed ECE during FWEH is well explained by the theoretical model, which indicates generation of the appreciable energetic fast electrons by the fast waves. New four-loop array antennas have been employed to improve the absorption of unidirectionally-propagating waves. Characteristics of antenna loading resistance can be reproduced by a coupling calculation code. In JT-60, FWEH experiment in combination with lower hybrid current drive was performed. Power absorption efficiency of fast wave is substantially improved in combination with LHCD of relatively low power for both phasing modes. Bulk electron heating is observed with high-k // mode and coupling with fast electron is confirmed in hard X-ray emission with low-k // mode. The results are consistent with theoretical prediction based on 1.D full wave code. Synergetic effects between FWEH and LHCD are found. Coupling calculation indicates that eight-loop antenna is favourable for keeping high directivity in the required N // -range. Current drive efficiency is calculated with 1-D full wave code including trapped particle effects and higher harmonic ion cyclotron damping

    Objectives: The objectives of this study were to understand how mothers of children with physical and cognitive disabilities who engaged their children in community-based rehabilitation (CBR services in Lusaka, Zambia, perceived and described (1 the level of support they received and the barriers they encountered in terms of their child’s meaningful social participation; (2 the use and awareness of these barriers to identify and pursue advocacy strategies; and (3 hopes for their child’s future. Methods: Data were collected through semi-structured interviews with each mother in her home.Results: Findings revealed both support and barriers to the child’s social participation in relationship to their family, friends and community. Support also came from the CBR programme and mothers’ personal resourcefulness. Mothers identified their child’s school,their immediate environment and financial burdens as barriers to participation as well as their own personal insecurities and fears. Strategies to overcome barriers included internal and external actions. The mothers involved in the study hope their child’s abilities will improve with continued CBR services. Some mothers described a bleak future for their child due to alack of acceptance and access to education. Conclusion: The findings of this study suggest the significant role the mother of a child with a disability plays in her child’s social participation. Recommendations include enhancing CBR programming for families, especially for mothers, and advocating on behalf of children with disabilities and their families to attract the attention of policy makers.

    Individuals with schizophrenia typically suffer a range of cognitive deficits, including prominent deficits in working memory and executive function. These difficulties are strongly predictive of functional outcomes, but there is a paucity of effective therapeutic interventions targeting these deficits. Transcranial direct current stimulation is a novel neuromodulatory technique with emerging evidence of potential pro-cognitive effects; however, there is limited understanding of its mechanism. This was a double-blind randomized sham controlled pilot study of transcranial direct current stimulation on a working memory (n-back) and executive function (Stroop) task in 28 individuals with schizophrenia using functional magnetic resonance imaging. Study participants received 30 min of real or sham transcranial direct current stimulation applied to the left frontal cortex. The 'real' and 'sham' groups did not differ in online working memory task performance, but the transcranial direct current stimulation group demonstrated significant improvement in performance at 24 h post-transcranial direct current stimulation. Transcranial direct current stimulation was associated with increased activation in the medial frontal cortex beneath the anode; showing a positive correlation with consolidated working memory performance 24 h post-stimulation. There was reduced activation in the left cerebellum in the transcranial direct current stimulation group, with no change in the middle frontal gyrus or parietal cortices. Improved performance on the executive function task was associated with reduced activity in the anterior cingulate cortex. Transcranial direct current stimulation modulated functional activation in local task-related regions, and in more distal nodes in the network. Transcranial direct current stimulation offers a potential novel approach to altering frontal cortical activity and exerting pro-cognitive effects in schizophrenia. © The Author (2017).

    Full Text Available Background and objective: Cancer is one of the most common diseases and the second reason of death in Iran. Giving decision making authority to patients is one of the fundamental principles of the protection of patients. Patients have rights as consumers of health care services that nurses, physician and other health professionals are responsible for maintaining and protecting it. This study aimed to determine cancer patients’ involvement in treatment decisions making. Methods: This cross-sectional study was carried out as descriptive-analytic with practical purpose in 2017 in Zahedan University of Medical Sciences. The study population included 1,000 patients who had cancer that whom 450 patients were selected by simple random sampling. To measure patient participation in treatment decisions, was used of Levente Kristona standard questionnaire. Reliability and validity of the questionnaire was confirmed (coefficient = 0.82. For data analysis used of software spss21 with descriptive statistics and chi-square tests Results: among the patients, 197 men (53% and 177 women (47% with a mean age of 31 years were examined. The results of this study showed that the score of mean participation in treatment decisions among the cancer patients was 30 ± 12 and it was in low level. The patients’ participation in treatment decisions had a significant relationship with education level (P = 0.027, however, it was not statistical significant with gender, age, income, occupation and type of cancer and other demographic variables (P> 0.05. Conclusion: In general, that patients' participation in clinical decision making is weak and low. Since patients’ participation in clinical decisions could affect the quality of treatment decisions, therefore, health care providers should attention more to this fact. Also, culturalizating and education according to patients’ knowledge and use of treatment techniques are recommended for clinical decision making promotion

    Results of long term studies of epidemiological and immunological problems after radiation accidents in Ural. At Chernobyl and nuclear weapons tests in Semi-palatinsk and Novaya Zemlya nuclear tests sites are presented. Changes in Health and immunity status of emergency team workers (liquida-tors) and participants on nuclear weapon tests were recorded in long term studies af-ter 10 and more years after radiation exposure. Some changes (decrease in ly-sozyme activity, disimmunoglobulinemia) could be attributed to the old age of exam-ined persons and concomitant cardiovasculatory, respiratory and other diseases An-other ones were related to the autoimmune syndromes. Humoral and cellular auto-immune changes were more pronounced in liquidators and participants then in controls. concentrations of antitissue antibodies in exposed cohort was three times higher than in control. Level of antibodies to thyroid antigens (microsoms and thy-roglobulines) were five times higher in liquidators of Chernobyl accident. The pos-sible role of humoral and cell autoimmune changes in the development of cardiovascular, liver, kidney and thyroid is considered. Considerable increase in some cytocine concentrations in blood of participants was found. For example increased concentration of TNF was recorded in half of par-ticipants from Novaya Zemlya in comparison to similar changes in only twenty pro-cents of controls. In half of participants from Semipalatinsk site the virus antigens in epithelium of higher respiratory tract (mostly adenoviruses) were found, with 22% in control group. In health and immunity studies of population from the contaminated areas after accidents and nuclear tests (Ural, Bryansk, Russian arktics) the demographics changes, mortality structure changes, oncological mortality and immunological deficiencies were found. The recorded effects might by considered as a results of combined effect of ra-diological and non-radiological factors. The potentiated effect of chronic

    Scientific knowledge about symptoms of common mental disorders in professional cricket is non-existent. Consequently, the aims of the study were to determine the prevalence and the 6 months incidence of symptoms of common mental disorders (CMD: distress, anxiety/depression, sleep disturbance, adverse alcohol use) among current and former professional cricketers and to explore the association of potential stressors (significant injury, surgery, adverse life events, career dissatisfaction) and CMD. An observational prospective cohort study with a follow-up period of 6 months was conducted among current and former professional cricketers from South Africa. Using validated questionnaires to assess symptoms of common mental disorders as well as several stressors, an electronic questionnaire was set up and distributed by the South African Cricketers Association (SACA). A total of 116 participants enrolled at baseline (overall response rate of 33%) and 76 of those participants completed the 6 month follow-up (follow up rate of 66%). The prevalence of symptoms of CMD in current professional cricketers was 38% for distress, 38% for sleep disturbance, 37% for anxiety/depression and 26% for adverse alcohol use. Among former professional cricketers, baseline prevalence as was 26% for distress, 24% for anxiety/depression, 21% for sleep disturbance and 22% for adverse alcohol use. Career dissatisfaction led to an increased risk of distress, anxiety/depression and sleep disturbance in current professional cricketers. Surgeries and adverse life events led to an increase in reported symptoms of distress and anxiety/depression in current professional cricketers. It was concluded that symptoms of CMD are prevalent in both current and former professional cricketers and the association with surgery, adverse life events and cricket career dissatisfaction may provide some insight into possible mechanisms.

    The Learner-Centered Student-run Clinic (LC-SRC) was designed to teach and train prescribing skills grounded in a real-life context, to provide students with early clinical experience and responsibility. The current studies' theoretical framework was based on the Self-determination Theory. According to the Self-determination Theory, early involvement in clinical practice combined with a high level of responsibility makes the LC-SRC an environment that can stimulate intrinsic motivation. We investigated the different types of motivation and the proficiency in CanMEDS competencies of the participating students. Type of motivation was measured using the Academic Motivation Scale and Intrinsic Motivation Inventory. CanMEDS competencies were evaluated by faculty using a mini-clinical examination and by the students themselves using a post-participation questionnaire. The 29 participating students were highly intrinsic motivated for this project on all subscales of the Intrinsic Motivation Inventory. Motivation for medical school on the Academic Motivation Scale was high before and was not significantly changed after participation. Students considered that their CanMEDS competencies "Collaborator", "Communicator", "Academic", and "Medical expert" had improved. Their actual clinical team competence was judged by faculty to be at a junior doctor level. Students showed a high level of intrinsic motivation to participate in the LC-SRC and perceived an improvement in competence. Furthermore their actual clinical competence was at junior doctor level in all CanMEDS competencies. The stimulating characteristics of the LC-SRC, the high levels of intrinsic motivation and the qualitative comments of the students in this study makes the LC-SRC an attractive place for learning.

    2012-09-01

    Full Text Available Introduction: We examined the accuracy of research participant characterizations of motor vehicle collisions (MVC.Methods: We conducted an emergency department-based prospective study of adults presenting for care after experiencing an MVC. Study participants completed a structured clinical interview that assessed the number of lanes of the road where the collision took place, vehicle type, road condition, speed limit, seat belt use, airbag deployment, vehicle damage, time of collision, and use of ambulance transportation. Study participant data were then compared with information recorded by Michigan State Police at the scene of the MVC. Agreement between research participant reports and police-reported data were assessed by using percentage agreement and j coefficients for categorical variables and correlation coefficients for continuous variables.Results: There were 97 study participants for whom emergency department interviews and Michigan State Police Report information were available. Percentage agreement was 51% for number of lanes,76% for car drivability, 88% for road condition, 91% for vehicle type, 92% for seat belt use, 94% for airbag deployment, 96% for speed limit, 97% for transportation by ambulance, and 99% for vehicle seat position. j values were 0.32 for seat belt use, 0.34 for number of lanes, 0.73 for vehicle type, 0.76 for speed limit, 0.77 for road condition, 0.87 for airbag deployment, 0.90 for vehicle seat position, and 0.94for transport by ambulance. Correlation coefficients were 0.95 for the time of the collision, and 0.58 for extent of damage to the vehicle. Most discrepancies between patients and police about extent of vehicle damage occurred for cases in which the patient reported moderate or severe damage but the police reported only slight damage.Conclusion: For most MVC characteristics, information reported by research participants was consistent with police-reported data. Agreement was moderate or high for

    Introduction Autism is associated with high cost to individuals, families, communities and government. Understanding educational and participation trajectories during the school years, and factors influencing these, is fundamental to reducing financial and personal costs. The primary aim of this study is to document the trajectories of Australian students with autism during their education. The secondary aim is to examine personal (eg, student skills) and environmental (eg, school setting) factors associated with differing trajectories and outcomes. Methods and analysis The cross-sequential longitudinal study will recruit two cohorts of 120 parents/caregivers of children with autism. Cohort 1 aged between 4 and 5 years and cohort 2 between 9 and 10 years to start the study. Information will be gathered from parents, teachers and school principals at six annual time points (T1 to T6). Parents will be emailed a link to an online initial questionnaire (T1) and then contacted annually and asked to complete either an extended questionnaire (T3, T5 and T6) or an abbreviated questionnaire (T2, T4). Where consent is given, the child’s current school will be contacted annually (T1 to T6) and teacher and school principal asked to complete questionnaires about the child and school. Parent and school questionnaires are comprised of questions about demographic and school factors that could influence trajectories and a battery of developmental and behavioural assessment tools designed to assess educational and participation trajectories and outcomes. Surveys will provide longitudinal data on educational and participation trajectories for children and adolescents with autism. In addition cross-sectional comparisons (within or between age groups) at each time point and cohort effects will be explored. Ethics and dissemination Ethics approvals have been granted for this study by all recruiting sites and universities in the project. Study findings will inform policy and practice

    The usefulness of thermoluminescence (TL) in geological studies is being increasingly recognized, as may be judged from the considerable volume of literature accumulated over the past couple of decades; besides, a number of seminars, conferences and specialists' meetings have also been held on the subject of applied TL. However, these publications lie scattered over several periodicals and conference proceedings and an interested worker finds it difficult to obtain the gist of the contributions in one place. The present authors felt a need for this and have, therefore, attempted to bring together in this Report the current status of TL research about different minerals; applications in the fields of geochronology, ore-prospecting, stratigraphic correlation, geothermometry and other useful areas are also included.

    Public participation and environmental impact assessment (EIA) are recent developments in Hungary; in spite of this considerable advances have been made in their development. Hungarian EIA offers a range of public participation mechanisms depending on the year the permitting process began as well as the sector to which the project corresponds, offering a good range of examples to study and compare. Three case studies have been selected, each making use of different public participation schemes: (1) a hazardous waste incinerator, falling under the 1993 provisional EIA decree; (2) a power plant, falling under the 1993 provisional EIA decree as well as the 1994 Energy Act; and (3) a motorway previous to any EIA legislation but having to meet EBRD`s EIA requirements, the motorways planning process, and the developer`s own initiative for participation. The system`s strengths and weaknesses are identified, as well as lessons drawn from international EIA theory and practice, such as the need for including early public involvement and a formal scoping phase.

    Drug shortages were a complex global problem. The aim of this study was to analyze, characterize, and assess the drug shortages, and identify possible solutions in Shaanxi Province, western China. A qualitative methodological approach was conducted during May-June 2015 and December 2015-January 2016. Semi-structured interviews were performed to gather information from representatives of hospital pharmacists, wholesalers, pharmaceutical producers, and local health authorities. Thirty participants took part in the study. Eight traditional Chinese medicines and 87 types of biologicals and chemicals were reported to be in short supply. Most were essential medicines. Five main determinants of drug shortages were detected: too low prices, too low market demands, Good Manufacturing Practice (GMP) issues, materials issues, and approval issues for imported drugs. Five different solutions were proposed by the participants: 1) let the market decide the drug price; 2) establish an information platform; 3) establish a reserve system; 4) enhance the communication among the three parties in the supply chain; and 5) improve hospital inventory management. Western China was currently experiencing a serious drug shortage. Numerous reasons for the shortage were identified. Most drug shortages in China were currently because of "too low prices." To solve this problem, all of the stakeholders, especially the government, needed to participate in managing the drug shortages.

    Recruitment of large, diverse populations into genetic studies remains challenging. Potential strategies to overcome limitations include leveraging electronic health data and minimizing patient burden. We sought to describe the overall participation rate and identify characteristics associated with participation in a genetic substudy of patients with type 2 diabetes mellitus, in which patients were identified via electronic hospital data and asked to participate by providing DNA samples by mail. During a phone interview, participants (n = 455) were asked to take part in a genetic substudy. Subjects verbally consenting were mailed saliva collection kits and written consent forms. We examined demographic and clinical variables associated with verbal consent and DNA kit return using logistic regression. Overall, 90% (n = 410) verbally consented to the genetic substudy during interviews. However, of those consenting, only 70% returned the DNA kit (n = 287). Among those consenting, after covariate adjustment, male sex (odds ratio [OR], 1.70; 95% confidence interval [CI], 1.09-2.65), African American race (OR, 0.61; 95% CI, 0.39-0.95), hemoglobin A1c (HbA1c) (OR, 0.87; 95% CI, 0.75-1.00), and physical activity (OR, 0.58; 95% CI, 0.37-0.91) were significantly associated with DNA kit return. To our knowledge, we are the first to demonstrate an inverse association between HbA1c and participation in genetic research, potentially indicating a compliance-related trait needing further exploration. The DNA kit return rate being notably lower than the verbal consent rate suggests that the greater convenience of a telephone/mail-in process did not drastically enhance full participation. Direct comparison to in-person donation may be warranted.

    Insights from genetic research may greatly improve our understanding of physical and mental illnesses and assist in the prevention of disease. Early experience with genetic information suggests that it may lead to stigma, discrimination, and other psychosocial harms, however, and this may be particularly salient in some settings, such as the workplace. Despite the importance of these issues, little is known about how healthy adults, including workers, perceive and understand ethically important issues in genetic research pertaining to physical and mental illness. We developed, pilot tested, and administered a written survey and structured interview to 63 healthy working adults in 2 settings. For this paper, we analyzed a subset of items that assessed attitudes toward ethically relevant issues related to participation in genetic research on physical and mental illness, such as its perceived importance, its acceptability for various populations, and appropriate motivations for participation. Our respondents strongly endorsed the importance of physical and mental illness genetic research. They viewed participation as somewhat to very acceptable for all 12 special population groups we asked about, including persons with mental illness. They perceived more positives than negatives in genetic research participation, giving neutral responses regarding potential risks. They affirmed many motivations for participation to varying degrees. Men tended to affirm genetic research participation importance, acceptability, and motivations more strongly than women. Healthy working persons may be willing partners in genetic research related to physical and mental illnesses in coming years. This project suggests the feasibility and value of evidence-based ethics inquiry, although further study is necessary. Evidence regarding stakeholders' perspectives on ethically important issues in science may help in the development of research practices and policy.

    Mindfulness-Based Stress Reduction (MBSR) is associated with reduced depressive symptoms, quality of life improvements, behavioral activation, and increased acceptance among veterans. This study was conducted to increase the reach and impact of a veterans' MBSR program by identifying barriers to enrollment and participation to inform modifications in program delivery. Verify or challenge suspected barriers, and identify previously unrecognized barriers, to enrollment and participation in MBSR among veterans. A retrospective qualitative analysis of semistructured interviews. VA Puget Sound Health Care System (Seattle, WA). 68 interviewed, and 48 coded and analyzed before reaching saturation. Content analysis of semistructured interviews. Of the participants who enrolled, most (78%) completed the program and described MBSR positively. Veterans identified insufficient or inaccurate information, scheduling issues, and an aversion to groups as barriers to enrollment. Participants who discontinued the program cited logistics (e.g., scheduling and medical issues), negative reactions to instructors or group members, difficulty understanding the MBSR practice purposes, and struggling to find time for the practices as barriers to completion. Other challenges (cohort dynamics, teacher impact on group structure and focus, instructor lack of military service, and physical and psychological challenges) did not impede participation; we interpreted these as growth-facilitating challenges. Common conditions among veterans (chronic pain, posttraumatic stress disorder, and depression) were not described as barriers to enrollment or completion. Women-only MBSR groups and tele-health MBSR groups could improve accessibility to MBSR for veterans by addressing barriers such as commute anxiety, time restrictions, and an aversion to mixed gender groups among women. Educating MBSR teachers about veteran culture and health challenges faced by veterans, adding psychoeducation materials that

    The goal of the prospective Adventist Health Study-2 (AHS-2) was to examine the relationship between diet and risk of breast, prostate and colon cancers in Black and White participants. This paper describes the study design, recruitment methods, response rates, and characteristics of Blacks in the AHS-2, thus providing insights about effective strategies to recruit Blacks to participate in research studies. We designed a church-based recruitment model and trained local recruiters who used various strategies to recruit participants in their churches. Participants completed a 50-page self-administered dietary and lifestyle questionnaire. Participants are Black Seventh-day Adventists, aged 30-109 years, and members of 1,209 Black churches throughout the United States and Canada. Approximately 48,328 Blacks from an estimated target group of over 90,000 signed up for the study and 25,087 completed the questionnaire, comprising about 26% of the larger 97,000 AHS-2-member cohort. Participants were diverse in age, geographic location, education, and income. Seventy percent were female with a median age of 59 years. In spite of many recruitment challenges and barriers, we successfully recruited a large cohort whose data should provide some answers as to why Blacks have poorer health outcomes than several other ethnic groups, and help explain existing health disparities.

    Bias with regard to participation in epidemiological studies can have a large impact on the generalizability of results. Our aim was to investigate the direction and magnitude of potential bias by comparing health-related factors among participants and non-participants in a MRI-study based on HUNT, a large Norwegian health survey. Of 14,033 individuals aged 50–65, who had participated in all three large public health surveys within the Norwegian county of Nord-Trøndelag (HUNT 1, 2 and 3), 1,560 who lived within 45 minutes of travel from the city of Levanger were invited to a MRI study (MRI-HUNT). The sample of participants in MRI-HUNT (n = 1,006) were compared with those who were invited but did not participate (n = 554) and with those who were eligible but not invited (n = 12,473), using univariate analyses and logistic regression analyses adjusting for age and education level. Self-reported health did not differ between the three groups, but participants had a higher education level and were somewhat younger than the two other groups. In the adjusted multivariate analyses, obesity was consistently less prevalent among participants. Significant differences in blood pressure and cholesterol were also found. This is the first large population-based study comparing participants and non-participants in an MRI study with regard to general health. The groups were not widely different, but participants had a higher level of education, and were less likely to be obese and have hypertension, and were slightly younger than non-participants. The observed differences between participants and non-invited individuals are probably partly explained by the inclusion criterion that participants had to live within 45 minutes of transport to where the MRI examination took place. One will expect that the participants have somewhat less brain morphological changes related to cardiovascular risk factors than the general population. Such consequences underline the crucial importance

    In order to design coastal structures and marine vehicles safely, it is required to know current climate which shows the variation of the current characteristics with time. There are a wide variety of current meters designed to measure water flow today. Each current meter is capable of recording the influence of mooring arrangement. Here we describe sea water temperatures, salinities and current velocities at offshore of Akburun, Tatlicak Burnu, Kalem Burnu and Kizil Burun areas in Cesme Peninsula 27 August, 1986 to 19 November, 1986. At the end of the investigations, measured significant maximum and average current velocities have been routinely analysed with micro-computers and also the percentages of current velocity have been calculated.

    Sport participation has been associated with improved life prospects such as academic performance and employability prospects. As such, promoting sport participation might be a way to increase life prospects, especially for socially vulnerable youth because they are less physically active than their peers. However, the evidence for the causal effect of sport participation on these outcomes is still limited and little is known about factors that play a role in this possible effect. The aim of this study is four-fold. First, the causal effect of sport participation on life prospects is studied and the underlying mechanisms of this relation are explored. Secondly, the life experiences of the youngsters in the sport context, that may contribute to skill development, are studied. Thirdly, social conditions for a positive effect are explored, as sport is likely to have a positive effect under specific conditions. Fourthly, this study aims to provide insights on the elements of successful partnerships between youth care organisations and local sport clubs. This protocol reports on a mixed method study. An intervention that aims to increase the sport participation of socially vulnerable youth, between 12-23 years old, is implemented in three regions of a Rotterdam youth care organisation. The youngsters in the two control regions receive care-as-usual. The main outcome variables, collected via questionnaires, are the life prospect, sense of coherence and self-regulation skills of the youngsters after 6 and 18 months of follow-up. The Motivational Climate Scale is administered to explore the social conditions for a positive effect and interviews are conducted with sport coaches to explore their role in skill development. Interviews with the youngsters are conducted to gain insight on the life experiences that may lead to skill development. The elements of successful partnerships are collected during interviews with youth care professionals, sport coaches and other

Thirdly, social conditions for a positive effect are explored, as sport is likely to have a positive effect under specific conditions. Fourthly, this study aims to provide insights on the elements of successful partnerships between youth care organisations and local sport clubs. Methods and design This protocol reports on a mixed method study. An intervention that aims to increase the sport participation of socially vulnerable youth, between 12–23 years old, is implemented in three regions of a Rotterdam youth care organisation. The youngsters in the two control regions receive care-as-usual. The main outcome variables, collected via questionnaires, are the life prospect, sense of coherence and self-regulation skills of the youngsters after 6 and 18 months of follow-up. The Motivational Climate Scale is administered to explore the social conditions for a positive effect and interviews are conducted with sport coaches to explore their role in skill development. Interviews with the youngsters are conducted to gain insight on the life experiences that may lead to skill development. The elements of successful partnerships are collected during interviews with youth care professionals

More cases (65.4% than controls (50.7% perceived that the main purpose of pharmaceutical research is to cure more diseases and to do so more effectively. In addition, more cases considered that there are significant benefits when participating in a research study, such as excellent medical care and extra free services, with this being the most important motivation to participate for both groups (cases 52%, controls 54.5%. We also found a sense of trust in their physicians to deal with adverse events, and the perception that clinical research is a benefit to their health, rather than a risk. More controls believed that clinical trial participants’ health is put at risk

    This study focuses on possible effects of specialized summer camps on young burn survivors' self esteem and body image. Quantitative as well as qualitative measures was used. To study possible effects, a pretest-posttest comparison group design with a follow-up was employed. Self-report questionnaires were used to measure self esteem and body image in a burn camp group (n=83, 8-18 years) and in a comparison group of children with burns who did not attend a burn camp during the course of the study (n=90, 8-18 years). Additionally, burn camp participants and parents completed an evaluation form about benefits derived from burn camp. A small positive short-term effect of burn camp participation was found on the 'satisfaction with appearance' component of body image. Overall, participants and parents showed high appreciation of the burn camps and reported several benefits, particularly concerning meeting other young burn survivors. Albeit statistically modest, this is the first quantitative study to document on a significant short-term impact of burn camp on young burn survivors' body image. Implications of this result for future research and burn camp organization were discussed, including the strengths of residential camps for young burn survivors.

    1998-03-01

    The present paper is an analysis of the results of epidemiological studies in Belarus about the after-effects of the accident at the Chernobyl atomic power station (ChAPS), based on published data at scientific institutes, organs and institutions of Ministry of Health. In the last years the affected population showed thereby more significant - as compared with republican indices - growth of incidence in the majority of diseases (first of all: digestion, urogenital, nervous, endocrine systems, diseases of ear, throat, nose both among adults and among children). Aggravation of health state continues in the participants of liquidation of the ChAPS accident consequences and the evacuees from the alienation zone which have obtained considerable radiation load to organism (rise of incidence of diseases of endocrine, cardiovascular, nervous system etc.). Considerable growth of thyroid cancer incidence is registered in Belarus children and adolescents, especially in the Gomel and Brest regions. This is conditioned by dose commitments on thyroid gland due to iodine radionuclides in first period after the accident, incorrect iodine prophylaxy, and goitre endemic. The rise of hereditary pathology is registered too. An expressed increase of oncological diseases is observed therewith mainly in the Gomel region, especially in the districts with high level of radiocontamination and, consequently, significant radiation load. First of all, this relates to the growth of incidence of cancer of lungs, mammary gland, bladder. The analysis of epidemiological studies performed in Belarus after the ChAPS catastrophe and comparison of them with data obtained in the pre-Chernobyl period testify to the aggravation of health state of Belarus population. The specialists unambiguously recognize the direct influence of radioactive pollution in the environment on rise of thyroid pathologies, hereditary and congenial diseases, and cancers of different localizations. There is no unique opinion

    Exergames are active video games that monitor body movement and are being used as an alternative to increase the level of physical activity of people from different age groups. This qualitative study investigated the perceptions of the elderly regarding exergaming. The focus group (FG) was conducted after 12 weeks of performing a program ofexergaming-based exercise (50 min, 3 days/week) using electronic games that simulate sports activities (Xbox 360 Kinect Sportstm). Fourteen people (55-77 years of age) participated in the FG, and a trained moderator led each group. The sessions were videotaped and transcribed for subsequent analysis. The content analysis technique was performed using ATLAS.ti® (qualitative analysis software). Participants reported psychological benefits (self-esteem, concentration, mood, reasoning, memory and well-being), physical benefits (agility and physical conditions) and social interaction (exchange of experiences, friendship and competitiveness). Regarding the experiences of the group, innovation, playfulness and visual stimulation were cited as characteristics of the games. The perception of benefits from participation in exergames fosters adherence to exercise and increases the motivation of the participants.

    Breast cancer diagnosis generally causes a disruption of occupational life. The purpose of this study was to explore the role of occupational participation and environment in the perception of health and well-being of Icelandic women with breast cancer. Eighteen women were interviewed using the main areas from the Occupational Performance History Interview as a guideline. An inductive analysis revealed seven categories that were organized under two main headings: occupational participation and environment. The categories were labelled "maintaining control and stability", "experiencing sense of self-worth", "enhancing self development", "access to information", "support and care", "refuge in community", and "rehabilitative opportunities". Through occupational participation the women were able to regain control of life and a sense of competence and development. Information, emotional support, safety, and stimulating environments were crucial in alleviating distress and facilitate satisfactory coping with the cancer experience. The results support that occupational participation in a safe and supportive environment has powerful restorative properties. Rehabilitative and supportive services should be based on a holistic perspective and emphasize the healthy aspects of a women's life. Furthermore, occupational therapists need to widen their approach when working with women with breast cancer and focus on their needs as occupational beings.

    Social dynamics within social participation is a crucial issue for the accomplishment of forest conservation. In order to contribute to this field, a study of 31 institutional and community organized actors' cooperative practices, within forest conservation processes in Paipa and Duitama, located at the oak forests conservation corridor Guantiva, La Rusia, Iguaque in Colombia, was made, applying Social Network Analysis (SNA). Particularly, this article inquiry is about models of participation of these actors within the period of 2004-2008, looking at their projects and actions as management practices of forest conservation. The research questions were how social participation is included and understood in the conservation of these oak forests, observing cooperative practices amongst this set of actors, at local level. The results are related with the structural patterns of co-participation established amongst these actors within each other's projects and actions and the impact of those in the aim of forest conservation at local level, regarding power relations and its impact on forest conservation.

    Patients with fibromyalgia syndrome are often severely restricted in their ability to participate in everyday activities and in social interaction. The aim of this study was to document female patients' subjectively-perceived limitations in participation and to develop material to generate items for a specific participation questionnaire. We collected data from 8 groups of women with fibromyalgia syndrome (n=38), and developed a hierarchical system of categories using the patients' statements (ATLAS.ti; Qualitative Data Analysis). Our final group of categories contains 10 superordinate categories. Women with fibromyalgia syndrome often describe restrictions in their relationships with other people, and the impaired ability to engage in social and leisure activities. They speak of difficulties at the workplace, while doing housework, and complain about a lack of understanding and awareness on the part of the general public. Fibromyalgia syndrome patients admit to be extremely impaired in a variety of social roles. Their statements have enabled us to develop a questionnaire that reflects the range of factors restricting participation from the patient's perspective.

    Full Text Available Abstract:  Guided by empowerment and ecological theories, the Youth Empowerment Solutions (YES program facilitates character development through activities based in cultural differences, team building, and social change. This pilot study consisted of two focus groups (n = 13 of middle school youth conducted after their participation in an abbreviated version of the YES program. Specifically, the present study examined youth’s cross-cultural perspectives after participation. The focus groups were transcribed and coded for emergent themes using Heaton’s (2005 supplementary data analysis framework. Qualitative analysis resulted in two emergent themes: 1 enhanced appreciation for similarities and differences in cultural and ethnic backgrounds, and 2 the role of respect in understanding differences and confronting stereotypes. Specifically, youth reported that engagement in this program fostered positive awareness of cultural differences and respect for inter-ethnic relationships. The findings provide support for the benefits of the YES program on moral development and promotion of healthy peer relationships.

  12. Rationing critical care medicine: recent studies and current trends.

    Ward, Nicholas S

    2005-12-01

    This paper reviews the literature on the rationing of critical care resources. Although much has been written about the concept of rationing, there have been few scientific studies as to its prevalence. A recent meta-analysis reviewed all previously published studies on rationing access to intensive care units but little is known about practices within the intensive care unit. Much literature in the past few years has focused on the growing use of critical care resources and projections for the future. Several authors suggest there may be a crisis in financial or personnel resources if some rationing does not take place. Other papers have argued that the methods of rationing critical care previously proposed, such as limiting the care of dying patients or using cost-effectiveness analysis to determine care, may not be effective or viewed as ethical by some. Finally, several recent papers review how critical care is practiced and allocated in India and Asian countries that already practice open rationing in their health care systems. There is currently no published evidence that overt rationing is taking place in critical care medicine. There is growing evidence that in the future, the need for critical care may outstrip financial resources unless some form of rationing takes place. It is also clear from the literature that choosing how to ration critical care will be a difficult task.

  13. Solar cycle in current reanalyses: (non)linear attribution study

    2014-12-01

    This study focusses on the variability of temperature, ozone and circulation characteristics in the stratosphere and lower mesosphere with regard to the influence of the 11 year solar cycle. It is based on attribution analysis using multiple nonlinear techniques (Support Vector Regression, Neural Networks) besides the traditional linear approach. The analysis was applied to several current reanalysis datasets for the 1979-2013 period, including MERRA, ERA-Interim and JRA-55, with the aim to compare how this type of data resolves especially the double-peaked solar response in temperature and ozone variables and the consequent changes induced by these anomalies. Equatorial temperature signals in the lower and upper stratosphere were found to be sufficiently robust and in qualitative agreement with previous observational studies. The analysis also pointed to the solar signal in the ozone datasets (i.e. MERRA and ERA-Interim) not being consistent with the observed double-peaked ozone anomaly extracted from satellite measurements. Consequently the results obtained by linear regression were confirmed by the nonlinear approach through all datasets, suggesting that linear regression is a relevant tool to sufficiently resolve the solar signal in the middle atmosphere. Furthermore, the seasonal dependence of the solar response was also discussed, mainly as a source of dynamical causalities in the wave propagation characteristics in the zonal wind and the induced meridional circulation in the winter hemispheres. The hypothetical mechanism of a weaker Brewer Dobson circulation was reviewed together with discussion of polar vortex stability.

    This paper discusses how a research team negotiated the challenges of language differences in a qualitative study that involved two languages. The lead researcher shared the participants' language and culture, and the interviews were conducted using the Arabic language as a source language, which was then translated and disseminated in the English language (target language). The challenges in relation to translation in cross-cultural research were highlighted from a perspective of establishing meaning as a vital issue in qualitative research. The paper draws on insights gained from a study undertaken among Arabic-speaking participants involving the use of in-depth semi-structured interviews. The study was undertaken using a purposive sample of 15 participants with Type 2 Diabetes Mellitus and co-existing depression and explored their perception of self-care management behaviours. Data analysis was performed in two phases. The first phase entailed translation and transcription of the data, and the second phase entailed thematic analysis of the data to develop categories and themes. In this paper there is discussion on the translation process and its inherent challenges. As translation is an interpretive process and not merely a direct message transfer from a source language to a target language, translators need to systematically and accurately capture the full meaning of the spoken language. This discussion paper highlights difficulties in the translation process, specifically in managing data in relation to metaphors, medical terminology and connotation of the text, and importantly, preserving the meaning between the original and translated data. Recommendations for future qualitative studies involving interviews with non-English speaking participants are outlined, which may assist researchers maintain the integrity of the data throughout the translation process.

    Augmentative and alternative communication (AAC) promotes communicative participation and language development for young children with complex communication needs. However, the motor, linguistic, and cognitive demands of many AAC technologies restrict young children's operational use of and influence over these technologies. The purpose of the current study is to better understand young children's participation in programming vocabulary "just in time" on an AAC application with minimized demands. A descriptive study was implemented to highlight the participation of 10 typically developing toddlers (M age: 16 months, range: 10-22 months) in just-in-time vocabulary programming in an AAC app with visual scene displays. All 10 toddlers participated in some capacity in adding new visual scene displays and vocabulary to the app just in time. Differences in participation across steps were observed, suggesting variation in the developmental demands of controls involved in vocabulary programming. Results from the current study provide clinical insights toward involving young children in AAC programming just in time and steps that may allow for more independent participation or require more scaffolding. Technology designed to minimize motor, cognitive, and linguistic demands may allow children to participate in programming devices at a younger age.

    2018-04-06

    OBJECTIVE There is a global lack of access to surgical care, and this issue disproportionately affects those in low- and middle-income countries. Global surgery academic collaborations (GSACs) between surgeons in high-income countries and those in low- and middle-income countries are one possible sustainable way to address the global surgical need. The objective of this study was to examine the barriers to participation in GSACs and to suggest ways to increase involvement. METHODS A convenience sample of 86 surgeons, anesthesiologists, other physicians, residents, fellows, and nurses from the US, Canada, and Norway was used. Participants were all health care providers from multiple specialties and multiple academic centers with varied involvement in GSACs. More than half of the participants were neurosurgeons. Participants were interviewed in person or over Skype in Toronto over the course of 2 months by using a predetermined set of open-ended questions. Thematic content analysis was used to evaluate the participants' responses. RESULTS Based on the data, 3 main themes arose that pointed to individual, community, and system barriers for involvement in GSACs. Individual barriers included loss of income, family commitments, young career, responsibility to local patients, skepticism of global surgery efforts, ethical concerns, and safety concerns. Community barriers included insufficient mentorship and lack of support from colleagues. System barriers included lack of time, minimal academic recognition, insufficient awareness, insufficient administrative support and organization, and low political and funding support. CONCLUSIONS Steps can be taken to address some of these barriers and to increase the involvement of surgeons from high-income countries in GSACs. This could lead to a necessary scale-up of global surgery efforts that may help increase worldwide access to surgical care.

  3. Current Highlights on ESA's Planetary Technology Reference Studies

    Science.gov (United States)

    Falkner, P.

    The concept of Technology Reference Studies has been introduced already at EGU05, where the Venus Entry Probe (VEP), the Jupiter Minisat Explorer (JME), the Deimos Sample Return (DSR) and the Interstellar Heliopause Probe (IHP) have been presented in detail. At the EGU06 the new studies in reaction to the Cosmic Vision exercise have been introduced. The formulation of themes and mapping into potential future missions has been taken as basis in the planning of additional new and adaptation of existing TRS's to cover areas, which have not yet been addressed by any TRS. These new ongoing studies are progressing well and current highlights will be presented in the paper in further detail as well as an overview on supporting technology studies and Concurrent Design Facility (CDF) sessions. The Jupiter System Explorer (JSE) study investigates mission concepts with up to two Magnetospheric Orbiters placed in a highly elliptical Jovian orbit and the possibility to deploy a Jovian Entry Probe. The mission profile is based on a solar powered concept launched on a Soyuz-Fregat launcher. Mission analysis and the application of a new Jovian radiation model are supporting the study activities. The Near-Earth Asteroid Sample Return (NEA-SR) concept explores the possibilities of sample return or in-situ mission profiles with visits to up to two NEA targets. Due to the assumed low cost cap a trade between a sample return and remote/in-situ exploration concept has a high attention in the study. The Cross Scale TRS (CS-TRS) is intended to simultaneously investigate magnetospheric and plasma processes in three spatial scales with a formation flight of up to 12 spacecraft, orbiting on deep elliptical orbits around Earth. One of the major challenges is the launch of that number of spacecraft on a single launcher and the collisionless deployment of the formation at the target orbit. The scope if the GeoSail TRS is to demonstrate deployment, attitude control and navigation concepts for a

    2009-01-01

    This study is a follow-up to a study previously published in this journal that reported the moderating function of exercise exertion amid the relationship between age and low back pain (LBP) among consistent exercise participants. The current study analyzed factors of psychological adaptation as potential mediators within the age--LBP relationship. Measures of psychological adaptation included psychological vulnerability, avoidant coping, resilient coping, and perceived resilience. The sample reported slightly moderate psychological vulnerability; a moderate extent of avoidant coping and resilient coping; and high resilience. Age inversely correlated with psychological vulnerability and avoidance coping. LBP correlated inversely with avoidant coping. Avoidant coping positively mediated (enhanced) age's effect on LBP. Results from this follow-up analysis highlight the importance of understanding and testing psychological factors in models with age and a physical health outcome.

  6. Study of current instabilities in high resistivity gallium arsenide

    International Nuclear Information System (INIS)

    Barraud, A.

    1968-01-01

    We have shown the existence and made a study of the current oscillations produced in high-resistivity gallium arsenide by a strong electric field. The oscillations are associated with the slow travelling of a region of high electrical field across the whole sample. An experimental study of the properties of these instabilities has made it possible for us to distinguish this phenomenon from the Gunn effect, from acoustic-electric effects and from contact effects. In order to account for this type of instability, a differential trapping mechanism involving repulsive impurities is proposed; this mechanism can reduce the concentration of charge carriers in the conduction band at strong electrical fields and can lead to the production of a high-field domain. By developing this model qualitatively we have been able to account for all the properties of high-resistance gallium arsenide crystals subjected to a strong electrical field: increase of the Hall constant, existence of a voltage threshold for these oscillations, production of domains of high field, low rate of propagation of these domains, and finally the possibility of inverting the direction of the propagation of the domain without destroying the latter. A quantitative development of the model makes it possible to calculate the various characteristic parameters of these instabilities. Comparison with experiment shows that there is a good agreement, the small deviations coming especially from the lack of knowledge concerning transport properties in gallium arsenide subjected to high fields. From a study of this model, it appears that the instability phenomenon can occur over a wide range of repulsive centre concentrations, and also for a large range of resistivities. This is the reason why it appears systematically in gallium arsenide of medium and high resistivity. (authors) [fr

    Full Text Available Abstract Background Previous studies have documented an elevated frequency of depressive symptoms and disorders in fibromyalgia, but have not examined the association between this comorbidity and occupational status. The purpose of this study was to describe these epidemiological associations using a national probability sample. Methods Data from iteration 1.1 of the Canadian Community Health Survey (CCHS were used. The CCHS 1.1 was a large-scale national general health survey. The prevalence of major depression in subjects reporting that they had been diagnosed with fibromyalgia by a health professional was estimated, and then stratified by demographic variables. Logistic regression models predicting labour force participation were also examined. Results The annual prevalence of major depression was three times higher in subjects with fibromyalgia: 22.2% (95% CI 19.4 – 24.9, than in those without this condition: 7.2% (95% CI 7.0 – 7.4. The association persisted despite stratification for demographic variables. Logistic regression models predicting labour force participation indicated that both conditions had an independent (negative effect on labour force participation. Conclusion Fibromyalgia and major depression commonly co-occur and may be related to each other at a pathophysiological level. However, each syndrome is independently and negatively associated with labour force participation. A strength of this study is that it was conducted in a large probability sample from the general population. The main limitations are its cross-sectional nature, and its reliance on self-reported diagnoses of fibromyalgia.

    Full Text Available Abstract Background Inappropriate medical treatment of co-morbidities in Alzheimer's disease (AD is an increasing concern in geriatric medicine. The objective of this study was to compare current drug use related to co-morbidity between individuals with a recent diagnosis of AD and a cognitively healthy control group in a population based clinical trial in Northern Norway. Methods Setting: Nine rural municipalities with 70 000 inhabitants in Northern Norway. Participants: Participants with and without AD recruited in general practice and by population based screening. 187 participants with a recent diagnosis of AD were recruited among community dwellers. Of 791 respondents without cognitive symptoms, 500 were randomly selected and invited to further clinical and cognitive testing. The final control group consisted of 200 cognitively healthy individuals from the same municipalities. Demographic characteristics, data on medical history and current medication were included, and a physical and cognitive examination was performed. The statistical analyses were carried out by independent sample t-test, chi-square, ANCOVA and logistic regression. Results A co-morbidity score was significantly higher in AD participants compared to controls. The mean number of drugs was higher for AD participants compared to controls (5.1 ± 3.6 and 2.9 ± 2.4 respectively, p Conclusions AD participants were treated with a significantly higher number of drugs as compared to cognitively healthy controls, even after adjustment for co-morbidity. An inappropriate use of anticholinergic and sedative drugs was identified, especially among nursing home residents with AD. The drug burden and the increased risk of adverse reactions among individuals suffering from AD need more attention from prescribing doctors.

    Biomedical research increasingly relies on long-term studies involving use and re-use of biological samples and data stored in large repositories or "biobanks" over lengthy periods, often raising questions about whether and when a re-consenting process should be activated. We sought to investigate the views on re-consent of participants in a longitudinal biobank. We conducted a qualitative study involving interviews with 24 people who were participating in a longitudinal biobank. Their views were elicited using a semi-structured interview schedule and scenarios based on a hypothetical biobank. Data analysis was based on the constant comparative method. What participants identified as requiring new consent was not a straightforward matter predictable by algorithms about the scope of the consent, but instead was contingent. They assessed whether proposed new research implied a fundamental alteration in the underlying character of the biobank and whether specific projects were within the scope of the original consent. What mattered most to them was that the cooperative bargain into which they had entered was maintained in good faith. They saw re-consent as one important safeguard in this bargain. In determining what required re-consent, they deployed two logics. First, they used a logic of boundaries, where they sought to detect any possible rupture with their existing framework of cooperation. Second, they used a logic of risk, where they assessed proposed research for any potential threats for them personally or the research endeavour. When they judged that a need for re-consent had been activated, participants saw the process as way of re-actualising and renewing the cooperative bargain. Participants' perceptions of research as a process of mutual co-operation between volunteer and researcher were fundamental to their views on consent. Consenting arrangements for biobanks should respect the cooperative values that are important to participants, recognise the two

    Full Text Available We studied the incidence and prevalence of, and co-factors for depression in the Swiss HIV Cohort Study.Depression-specific items were introduced in 2010 and prospectively collected at semiannual cohort visits. Clinical, laboratory and behavioral co-factors of incident depression among participants free of depression at the first two visits in 2010 or thereafter were analyzed with Poisson regression. Cumulative prevalence of depression at the last visit was analyzed with logistic regression.Among 4,422 participants without a history of psychiatric disorders or depression at baseline, 360 developed depression during 9,348 person-years (PY of follow-up, resulting in an incidence rate of 3.9 per 100 PY (95% confidence interval (CI 3.5-4.3. Cumulative prevalence of depression during follow-up was recorded for 1,937/6,756 (28.7% participants. Incidence and cumulative prevalence were higher in injection drug users (IDU and women. Older age, preserved work ability and higher physical activity were associated with less depression episodes. Mortality (0.96 per 100 PY, 95% CI 0.83-1.11 based upon 193 deaths over 20,102 PY was higher among male IDU (2.34, 1.78-3.09, female IDU (2.33, 1.59-3.39 and white heterosexual men (1.32, 0.94-1.84 compared to white heterosexual women and homosexual men (0.53, 0.29-0.95; and 0.71, 0.55-0.92.

    1986-01-01

    In this thesis the results of an analysis of inclusive neutrino and antineutrino interaction on deuterium nuclei are presented. The use of deuterium as a target provides a mean to study proton and neutron scattering separately. The presently accepted theory of electro-weak interactions is reviewed. Applications of the quark-parton model in the context of deep-inelastic neutrino interactions on nucleons are summarized. The concept of scaling and its consequences are treated, together with some sources of violation of scaling. The properties of the CERN wide-band neutrino beam and an overview of the elements of this beam are given. The method to determine the energy distribution and the composition of the neutrino and antineutrino beam is described. The technique employed to separate neutrino interactions on protons and neutrons is discussed. Results of the measurement of the total nucleon charged-current cross-sections and differential cross-sections are presented. The relative contributions of quarks and antiquarks to the neutrino cross-sections are deduced from y-distributions and compared to those obtained from the total cross-section measurements. Finally, the analysis of the structure functions is given. (Auth.)

    In an effort to achieve the objectives, the following provisions were made. First of all, how this project supported RCA events that were held in Korea during the project period was described. Also, participation in RCA major policy level meetings, RCA-30 Scientific Forum, RCA Regional Office Opening were briefly reviewed. Secondly, RCA's general features including history and objective of its establishment, basic policy, administrative structure, major meetings was also reviewed. Thirdly, Overview of RCA projects, project implementation mechanism, on-going and planned project, review of technology utilization so fat and success stories were described. Fourthly, the issues related to the effective RCA management such as lead countries, Regional Resources Units (RRUs), RCA future vision and outsourcing of technical cooperation projects were reviewed. Finally, proper strategies and recommendations for active implementation of RCA projects were presented. This study can be utilized as basic reference material in the efficient implementation of RCA programmes in the future and for the personnel involved in the RCA projects as the fundamental elements for implementing the RCA cooperation are presented. The effective implementation direction for RCA programmes and strategies for strengthening Korea's participation in RCA projects can be utilized as basic reference material for the effective planning and implementation of RCA projects. It is hoped that this study will be widely utilized for expanding Korea's participation in the RCA project and for establishing a future direction for RCA projects by the governments, industries, academic circles and research institutions

    We examined the association of burnout with borderline personality (BP) traits in a study of 1,163 educational staff (80.9% women; mean age: 42.96). Because burnout has been found to overlap with depression, parallel analyses of burnout and depression were conducted. Burnout symptoms were assessed with the Shirom-Melamed Burnout Measure, depressive symptoms with the PHQ-9, and BP traits with the Borderline Personality Questionnaire. Burnout was found to be associated with BP traits, controlling for neuroticism and history of depressive disorders. In women, burnout was linked to both the “affective insecurity” and the “impulsiveness” component of BP. In men, only the link between burnout and “affective insecurity” reached statistical significance. Compared to participants with “low” BP scores, participants with “high” BP scores reported more burnout symptoms, depressive symptoms, neuroticism, and occupational stress and less satisfaction with life. Disattenuated correlations between burnout and depression were close to 1, among both women (0.91) and men (0.94). The patterns of association of burnout and depression with the main study variables were similar, pointing to overlapping nomological networks. Burnout symptoms were only partly attributed to work by our participants. Our findings suggest that burnout is associated with BP traits through burnout-depression overlap. PMID:29375447

    Full Text Available This paper uses the most recent wave of a nationally representative dataset to examine the factors associated with elderly homeowners’ decision to obtain reverse mortgage loans. The findings of this study suggest that very few homeowners participated in the reverse mortgage market, and homeowners younger than 67 were less likely to have reverse mortgage loans. However, homeowners who were risk averse, and homeowners in the two highest quartiles of net worth were more likely to have reverse mortgage loans. Further analyses reveal that among the reverse mortgage participants, homeowners with long-term care insurance coverage were less likely to have reverse mortgage loans. Implications for financial economists, financial planners, policy-makers, and scholars of retirement economics are included.

    Few Asian-American women participate in cancer treatment trials. In a pilot study to assess barriers to participation, we mailed surveys to 132 oncologists and interviewed 19 Asian-American women with cancer from Northern California. Forty-four oncologists responded. They reported as barriers language problems, lack of culturally relevant cancer information, and complex protocols. Most stated that they informed Asian-American women about treatment trials. Only four women interviewed knew about trials. Other patient-identified barriers were fear of side effects, language problems, competing needs, and fear of experimentation. Family decision making was a barrier for both oncologists and patients. Compared to non-Asian oncologists, more Asian oncologists have referred Asian-American women to industry trials and identified barriers similar to patients' reports. Our findings indicate that Asian-American women need to be informed about cancer treatment trials, linguistic barriers should be addressed, and future research should evaluate cultural barriers such as family decision making.

    Full Text Available Abstract Background An increasing number of patients with chronic disorders and a more complex health service demand greater interdisciplinary collaboration in Primary Health Care. The aim of this study was therefore to identify factors related to general practitioners (GPs, their list populations and practice municipalities associated with a high rate of GP participation in multidisciplinary meetings (MDMs. Methods A national cross-sectional register-based study of Norwegian general practice was conducted, including data on all GPs in the Regular GP Scheme in 2007 (N = 3179. GPs were grouped into quartiles based on the annual number of MDMs per patient on their list, and the groups were compared using one-way analysis of variance. Binary logistic regression was used to analyse associations between high rates of participation and characteristics of the GP, their list population and practice municipality. Results On average, GPs attended 30 MDMs per year. The majority of the meetings concerned patients in the age groups 20-59 years. Psychological disorders were the motivation for 53% of the meetings. In a multivariate logistic regression model, the following characteristics predicted a high rate of MDM attendance: younger age of the GP, with an OR of 1.6 (95% CI 1.2-2.1 for GPs Conclusions Psychological problems including substance addiction gave grounds for the majority of MDMs. GPs with a high proportion of consultations with such problems also participated more frequently in MDMs. List size was negatively associated with the rate of MDMs, while a more disadvantaged list population was positively associated. Working in smaller organisational units seemed to facilitate cooperation between different professionals. There may be a generation shift towards more frequent participation in interdisciplinary work among younger GPs.

    The problem of non-thermal bremsstrahlung during lower hybrid current drive is considered. The proposed method shows the role of the Compton effects at low frequencies and allows us to establish the link between the emitted power and the absorbed power at high frequency. The non-thermal emission is considered as a kinematical mode conversion between the absorbed radio-frequency mode and the emitted X ray photons. The fast electrons diagnostics and the ways to reach the wave structure are shown. Kinetic and electromagnetic problems concerning current generation are described. The plasma properties and diagnostics in the case of a non inductive current generation are discussed [fr

    The purpose of this study was to examine lesbian and gay (LG) young adults' reactions to participating in intimate partner violence (IPV) and minority stress research using a mixed methodological design. Participants were 277 U.S. college students currently involved in same-sex relationships and self-identified cisgender LG who completed an online questionnaire that included closed- and open-ended questions. Results suggested that IPV research was well tolerated by the vast majority of participants; close to one in 10 participants reported being upset by the study questions, yet 75% of upset individuals reported some level of personal benefit. Reasons for upset as identified in the open-ended responses included thinking about personal experiences with IPV, as the perpetrator or friend of a victim, as well as thinking about the uncertainty of their future with their current partner. The correlates of emotional reactions and personal benefits to research participation were also examined, and these varied among gay men and lesbian women. Implications of these findings underscore the importance of accurate reflection of risk and benefits in informed consent documents as well as systematic evaluation of sexual minority participants' reactions to research participation in an effort to conduct ethically sound sexual science research.

    Unity power factor (UPF) harmonic current detection method applied to active power filter (APF) is presented in this paper. The intention of this method is to make nonlinear loads and active power filter in parallel to be an equivalent resistance. So after compensation, source current is sinusoidal, and has the same shape of source voltage. Meanwhile, there is no harmonic in source current, and the power factor becomes one. The mathematic model of proposed method and the optimum project for equivalent low pass filter in measurement are presented. Finally, the proposed detection method applied to a shunt active power filter experimental prototype based on DSP TMS320F2812 is developed. Simulation and experiment results indicate the method is simple and easy to implement, and can obtain the real-time calculation of harmonic current exactly.

    Steady-state operation of a fusion power plant requires external current drive to minimize the power requirements, and a high fraction of bootstrap current is required. One of the external sources for current drive is lower hybrid current drive, which has been widely applied in many tokamaks. Here, using lower hybrid simulation code, we calculate electron distribution function, electron currents and phase velocity changes for two options of demonstration reactor at the launched lower hybrid wave frequency 5 GHz. Two plasma scenarios pertaining to two different demonstration reactor options, known as pulsed (Option 1) and steady-state (Option 2) models, have been analyzed. We perceive that electron currents have major peaks near the edge of plasma for both options but with higher efficiency for Option 1, although we have access to wider, more peripheral regions for Option 2. Regarding the electron distribution function, major perturbations are at positive velocities for both options for flux surface 16 and at negative velocities for both options for flux surface 64.

    To describe the prevalence of visual impairment and examine its association with demographic, socioeconomic, and health characteristics in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort. Visual acuity data were obtained from 6134 participants, aged 46-87 years at time of examination between 2002 and 2004 (mean age 64 years, 47.6% male), from six communities in the United States. Visual impairment was defined as presenting visual acuity 20/50 or worse in the better-seeing eye. Risk factors were included in multivariable logistic regression models to determine their impact on visual impairment for men and women in each racial/ethnic group. Among all participants, 6.6% (n = 421) had visual impairment, including 5.6% of men (n = 178) and 7.5% of women (n = 243). Prevalence of impairment ranged from 4.2% (n = 52) and 6.0% (n = 77) in white men and women, respectively, to 7.6% (n = 37) and 11.6% (n = 44) in Chinese men and women, respectively. Older age was significantly associated with visual impairment in both men and women, particularly in those with lower socioeconomic status, but the effects of increasing age were more pronounced in men. Two-thirds of participants already wore distance correction, and not unexpectedly, a lower prevalence of visual impairment was seen in this group; however, 2.4% of men and 3.5% of women with current distance correction had correctable visual impairment, most notably among seniors. Even in the U.S. where prevalence of refractive correction is high, both visual impairment and uncorrected refractive error represent current public health challenges.

    Reviewed are the international trend of environmental radiation protection (ERP), Japanese studies of radiation effects on environmental livings from aspects of ecosystem to molecular level, and the future view. ERP is particularly closed up toward promotion after its first involvement in the general global conference, UN Conference on Environment and Development (1992). International Commission of Radiological Protection (ICRP) has conducted such actions for the environment as establishing protection essentials for non-human species (2003), organizing Committee 5 (2005), and defining Reference Animals and Plants (2008) where Derived Consideration Reference Levels of 0.1-100 mGy/d are proposed, together with cooperative actions by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), International Atomic Energy Agency (IAEA), The Organization for Economic Co-operation and Development (OECD)/Nuclear Energy Agency (NEA) and European projects. Japanese NIRS is now enrolled in the project of Environmental Modeling for Radiation Safety-II (IAEA). Major Japanese studies of radiation effects on environmental livings have utilized killifish (medaka: Oryzias latipes), springtail, earthworm, nematode, cultured plant cell (cedar), poplar, etc. Studies of the radiation effect on microcosm consisting of 3 livings have led to establishing a model for mathematical analysis and of 8 livings, have defined 50% affect dose of 5600 Gy gamma-ray. Irradiation of gamma-ray at 1 Gy/d for 5-10 days to the soil has been shown to result in alteration of the composition of natural earth bacterial population by denaturant gradient gel electrophoresis, which being a promising tool for evaluating the alteration of soil composition and function. At molecular levels, transcriptome analysis of various cells from yeast to man, is performed after irradiation of gamma-ray, neutron, heavy particles and others to reveal radiation-induced gene expression; and Hi-CEP (high

    The aim of this prospective cohort study was to investigate the nature and risk factors of injuries leading to hospitalization. A cohort of 57 407 Finns aged 14-18 years was followed in the Hospital Discharge Register for an average of 10.6 years, totaling 608 990 person-years. We identified 5889 respondents (10.3%) with injury hospitalization. The most common anatomical location was the knee and shin (23.9%), followed by the head and neck (17.8%), and the ankle and foot (16.7%). Fractures (30.4%) and distortions (25.4%) were the most common injury types. The strongest risk factor for injury hospitalization was frequent participation in sports clubs [hazard ratio (HR) in males 1.8; 95% confidence interval (CI): 1.7-2.0 and in females 2.3; 95% CI: 1.9-2.7], followed by recurring drunkenness (HR 1.6; 95% CI: 1.4-2.7 in males and 1.4; 95% CI: 1.2-1.6 in females) and daily smoking (HR 1.4; 95% CI: 1.3-1.5 in males and 1.43 95% CI: 1.2-1.5 in females). The association between injuries and sports clubs participation remained after adjusting for sociodemographic background, health, and health behaviors. Health behavior in adolescence, particularly sports club activity, predicted injury hospitalization. Preventive interventions directed toward adolescents who participate in sports clubs may decrease injury occurrence.

    Social-ecological models of health behaviour acknowledge environmental influences, but research examining how the environment shapes physical activity in rural settings is limited. This study aimed to explore the environmental factors that act as barriers or facilitators to physical activity participation among rural adults. Forty-nine adults from three regions of rural Tasmania, Australia, participated in semi-structured interviews that explored features of the environment that supported or hindered physical activity. Interviews were digitally recorded, transcribed verbatim and analysed thematically. Four key themes emerged: functionality, diversity, spaces and places for all and realistic expectations. 'Functionality' included connectivity with other destinations, distance, safety, continuity, supporting infrastructure and surfacing. While there was limited 'diversity' of structured activities and recreational facilities, the importance of easy and convenient access to a natural environment that accommodated physical activity was highlighted. 'Spaces and places for all' highlighted the importance of shared-use areas, particularly those that were family- and dog-friendly. Despite desires for more physical activity opportunities, many participants had 'realistic expectations' of what was feasible in rural settings. Functionality, diversity, spaces and places for all and realistic expectations were identified as considerations important for physical activity among rural adults. Further research using quantitative approaches in larger samples is needed to confirm these findings. SO WHAT? Urban-centric views of environmental influences on physical activity are unlikely to be entirely appropriate for rural areas. Evidence-based recommendations are provided for creating new or modifying existing infrastructure to support active living in rural settings.

    The use of Web-based methods for research recruitment and intervention delivery has greatly increased as Internet usage continues to grow. These Internet-based strategies allow for researchers to quickly reach more people. African-Americans are underrepresented in health research studies. Due to this, African-Americans get less benefit from important research that could address the disproportionate health outcomes they face. Web-based research studies are one promising way to engage more Afri...

    Reimbursement of trial participants remains a frequently debated issue, with specific guidance lacking. Trials combining post-trial access and implementation science may necessitate new strategies and models. CAPRISA 008, a post-trial access study testing the feasibility of using family planning services to rollout a prelicensure HIV prevention intervention, tried to balance the real-life scenario of no reimbursement for attendance at public sector clinics with that of a trial including some visits that focused on research procedures and others that focused on standard of care procedures. A reduced reimbursement was offered for 'standard of care' visits, meant primarily to cover transport costs to and from the clinic only. This impacted negatively on accrual, retention and participant morale, primarily due to the protracted delay in regulatory approval, during which time, the costs of living, including travel costs had increased. Relevant guidelines were reviewed and institutional policy was updated to incorporate the South African National Health Research Ethics Committee guidelines on reimbursement (taking into account participant time, travel and inconvenience). The reimbursement amount for 'standard of care' visits was increased accordingly. The question remains whether a trial that combines post-trial access with implementation science, with clear benefits for the participants and the provision of above standard medical care, should have reimbursement rates that approach those of a proof-of-concept trial, for 'standard of care' visits.

    The aim of this study is to assess the rate of work participation and disability pension, and identify predictors for sickness absence and disability pension, among morbidly obese individuals. The data were collected from the Obesity Surgery Registry at Førde Central Hospital and consists of patients undergoing bariatric surgery between April 2001 and February 2013. Multivariate logistic regression was performed to identify predictors of sickness absence and disability pension. The sample consisted of 576 patients (63.9 % females) with a mean (range, SD) age of 41.7 (18-66, 10.6) and a mean body mass index (BMI) of 47.7 (32.5-80.8, 7.7). Patients working full- or part-time comprised 55.6 % of the sample and 29.7 % received a disability pension; only 46.4 % of the sample received an income from paid work without additional benefits. Having a BMI above 50, lower levels of education, and suffering from four or more comorbidities were significant predictors of sickness absence. Female gender, psychiatric disorders, lower levels of education, asthma, heart failure and suffering from four or more comorbidities were significant predictors of disability pension. The proportion of the work participation and disability pension among this morbidly obese population is of substantial concern, as work participation has proven important for the health-related quality of life. This, combined with the fact that these patients are significantly less educated than the general population, can potentially have grave socioeconomic consequences. Increased knowledge of obesity development and the work history of these patients are needed to implement policies that ensure increased rates of work participation.

    Childhood malnutrition is a major consequence of poverty worldwide. Microcredit programmes-which offer small loans, financial literacy and social support to low-income individuals-are increasingly promoted as a way to improve the health of clients and their families. This study evaluates the hypothesis that longer participation in a microcredit programme is associated with improvements in the health of children of microcredit clients. Cross-sectional data were collected in February 2007 from 511 clients of a microcredit organisation in Peru and 596 of their children under 5 years of age. The primary predictor variable was length of participation in the microcredit programme. Outcome variables included height, weight, anaemia, household food security and parent-reported indicators of child health. Multivariate linear and logistic regressions assessed the association between the number of loan cycles and child health outcomes. Pathways through which microcredit may have influenced health outcomes were also explored via mediation analyses. Longer participation in microcredit was associated with greater household food security and reduced likelihood of childhood anaemia. No significant associations were observed between microcredit participation and incidence of childhood illnesses or anthropometric indicators. Increased consumption of red meat may mediate the association between the number of loan cycles and food security, but not the association with anaemia. The effects of microcredit on the health of clients' children are understudied. Exploratory findings from this analysis suggest that microcredit may positively influence child health, and that diet may play a causal role. Published by the BMJ Publishing Group Limited.

    Full Text Available Studies on female co-authorship in the scientific production of various areas of knowledge are frequent in international scientific literature. However, this object of study has been little explored by Brazilian research in the field of Information Science. This article presents a contribution to this area by presenting the results of a research that investigated female co-authorship and the participation of women in the editorial staff of Brazilian scientific journals in the area of surgery published between 2010 and 2014. The corpus investigated consisted of 920 articles published in four scientific journals: Acta Cirúrgica Brasileira (ACB, Arquivos Brasileiros de Cirurgia Digestiva (ABCD, Revista Brasileira de Cirurgia Cardiovascular (RBCCV and Revista do Colégio Brasileiro de Cirurgiões (RCBC. The bibliometric analysis is the methodological approach adopted and sample universe were 920 articles written by 5649 co-authors. Men appear as coauthors in 63.5% (n=585 of articles, while women show up as coauthors in 23.8% (219 of all articles. By investigating the gender of coauthorship in original and review articles, the results showed that women's participation is lower than men in both types and in all four journals. Observing the participation of women in editorial boards of the journals, the results revealed that in only one journal (ABCD the female presence is unique and exclusive. The study showed that gender inequality persists in terms of authorship, co-authorships, types of articles, and also on the editorial board, scientific committee and board of reviewers.

    Exergames (exercise-based videogames) for delivering strength and balance exercise for older people are growing in popularity with the emergence of new Kinect-based technologies; however, little is known about the factors affecting their uptake and usage by older people. The aim of this study was to determine the factors that may influence the motivation of older people to use exergames to improve their physical function and reduce fall risk. Mixed methods were employed in which 14 semistructured interviews were conducted with older people (n=12, aged 59-91 years) from 2 assisted living facilities in the North West of the United Kingdom. The older people participated in a 6-week trial of exergames along with one manager and one physiotherapist; 81 h of observation and Technology Acceptance Model questionnaires were conducted. The findings suggest that the participants were intrinsically motivated to participate in the exergames because of the enjoyment experienced when playing the exergames and perceived improvements in their physical and mental health and social confidence. The social interaction provided in this study was an important extrinsic motivator that increased the intrinsic motivation to adhere to the exergame program. The findings of this study suggest that exergames may be a promising tool for delivering falls prevention exercises and increasing adherence to exercise in older people. Understanding the motivation of older people to use exergames may assist in the process of implementation. ©Wytske Meekes, Emma Kate Stanmore.

    A statistical analysis of enrollment in AP maths and sciences in the Abilene Independent School District, between 2000 and 2005, studied the relationship between gender, enrollment, and performance. Data suggested that mid-scoring females were less likely than their male counterparts to enroll in AP-level courses. AISD showed higher female : male score ratios than national and state averages but no improvement in enrollment comparisons. Several programs are suggested to improve both participation and performance of females in upper-level math and science courses.

  17. Insights from an 8-Year Longitudinal Study of Female REU Participants

    Slater, S. J.

    2009-12-01

    The long-running REU program is tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. This 8-year, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women from a single scientific discipline. This paper describes the results of that analysis in two sections. The first section describes the results from an ex post facto longitudinal data analysis. This data included multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes, over an 8-year period. As a result of this analysis, four themes emerged, related to developing understandings of the nature of professional scientific work, the nature of the scientific process, the culture of academia, and finally, an understanding of the "self." This analysis served as an initial theory that was used to design the second stage, interview protocol. In the second stage over 10 hours of interviews with 8 participants were conducted and analyzed. These 8 participants were selected to represent a variety of career stages, and for their potential to disconfirm the initial theory. Analysis of this interview data failed to provide disconfirming evidence. Results from this study indicate that the REU did not provide a substantive educational experience related to the nature of scientific work, the scientific process, or the culture of academia. Results further indicated that the REU did not serve to transform participants' conceptions about themselves as situated in science, and learning gains with regard to other aspects of the self, were somewhat limited. Instead, the data suggests that these women arrived at the REU with pre-existing and remarkably strong conceptions in these areas, and that the REU did not functional to alter those states. These conceptions were frequently the

    2010-01-01

    Full Text Available Lack of homeowner participation in housing management (free riding has rendered the management of many apartment buildings in Hong Kong ineffective. Proper apartment-building management depends on the voluntary contributions of individual homeowners. Individual homeowners are likely to free-ride on the management efforts of others because they consider the benefits of good housing management to be common goods. Apart from incentives such as subsidies offered by public entities and stricter law enforcement against homeowners that neglect building care, researchers have claimed that communitarian solutions may also work to tackle housing-management problems. In particular, there has been growing interest in the use of social capital, which is regarded as an asset of trust, reciprocity and cooperation, to foster a participatory culture among individual property owners. Empirical study of whether social capital plays a necessary role in housing management has been lacking. This study examines the linkage between social capital and homeowner participation in housing management in Hong Kong. The findings of this study have significant policy and practical implications. In addition to financial incentives or disincentives, public administrators can work to build a sense of community to achieve sustainable management of the existing housing stock in Hong Kong.

    In November 2016, the Dutch Health Council recommended hepatitis B (HBV) screening for first-generation immigrants from HBV endemic countries. However, these communities show relatively low attendance rates for screening programmes, and our knowledge on their participation behaviour is limited. We identified determinants associated with the intention to request an HBV screening test in first-generation Moroccan-Dutch immigrants. We also investigated the influence of non-refundable costs for HBV screening on their intention. Offline and online questionnaires were distributed among first- and second/third-generation Moroccan-Dutch immigrants using respondent-driven sampling. Random forest analyses were conducted to determine which determinants had the greatest impact on (1) the intention to request an HBV screening test on one's own initiative, and (2) the intention to participate in non-refundable HBV screening at €70,-. Of the 379 Moroccan-Dutch respondents, 49.3% intended to request a test on their own initiative, and 44.1% were willing to attend non-refundable screening for €70,-. Clarity regarding infection status, not having symptoms, fatalism, perceived self-efficacy, and perceived risk of having HBV were the strongest predictors to request a test. Shame and stigma, fatalism, perceived burden of screening participation, and social influence of Islamic religious leaders had the greatest predictive value for not intending to participate in screening at €70,- non-refundable costs. Perceived severity and possible health benefit were facilitators for this intention measure. These predictions were satisfyingly accurate, as the random forest method retrieved area under the curve scores of 0.72 for intention to request a test and 0.67 for intention to participate in screening at €70,- non-refundable costs. By the use of respondent-driven sampling, we succeeded in studying screening behaviour among a hard-to-reach minority population. Despite the limitations

    A healthy diet is especially important during menopause, a period which increases the risk of various health problems. We analyzed the diet of periand postmenopausal Spanish women and the degree of compliance with current recommendations. We studied 3574 women 45-68 years old who attended breast cancer screening programmes in 7 centres (A Coruña, Barcelona, Burgos, Palma de Mallorca, Pamplona, Valencia and Zaragoza). Diet information was collected using a food frequency questionnaire validated for the Spanish population. For the assessment of compliance with current guidelines we used the recommendations by the Spanish Society of Community Nutrition for food groups intake and by the Spanish Federation of Nutrition, Food and Dietetics for energy, vitamins and minerals intake. The 29% of women were obese and 42% overweight. The average caloric intake was 2.053 kcal (SD 480). The general energy profile was: 43% of the energy from the carbohydrates, 36% from fats, and 20% from proteins. There was a low vitamin D intake in all centres of the study, with an overall mean intake of 2.14 mg/day. A deficit of vitamin E intake in A Coruña and Burgos was also detected. Intake of dairy products and vegetables was high in all the study centers. The consumption of fruits and vegetables was very heterogeneous, with high intakes observed in Mallorca and Valencia and low for both food groups in A Coruña. The olive oil intake was high in all centers except Burgos with 74.3% of the women studied below the recommended 3 servings per day. A diet with less fat and protein and a higher consumption of vegetables, nuts and foods rich in carbohydrate might balance the energy intake and improve the quality of the diet correcting the low intakes of vitamins D and E. These recommendations are especially important in cities far from the Mediterranean coast where more breaches have been detected over the current recommendations with a lower adherence to the Mediterranean diet.

    Full Text Available Community support and participation among persons with disabilities. A study in three European countriesThis article describes a European project which was aimed at improving the situation of persons with psychiatric or learning disabilities with regard to social participation and citizenship. The project took place in three countries (Estonia, Hungary and the Netherlands and four cities (Tallinn, Budapest, Amersfoort and Maastricht. The project included research and actions at the policy level, the organizational level and the practice level. At the policy level, the framework of the United Nations Convention on the Rights of Persons with Disabilities (United Nations, 2006 and the European Disability Strategy (European Commission, 2010 were used to look at national and local policies, at the reality of the lives of those with disabilities and at the support that professional services offer with regard to participation and inclusion. The project generated a number of insights, recommendations and methods by which to improve the quality of service and increase the number of opportunities for community engagement. In this article, we present some of the lessons learned from the meta-analysis. Although the circumstances in each country are quite different with regard to policy, culture and service systems, it is remarkable that people with disabilities face many of the same problems.The study shows that in all three countries, access to services could be improved. Barriers include bureaucratic procedures and a lack of services. The research identified that in every country and city there are considerable barriers regarding equal participation in the field of housing, work and leisure activities. In addition to financial barriers, there are the barriers of stigma and self-stigmatization. Marginalization keeps people in an unequal position and hinders their recovery and participation. In all countries, professionals need to develop a stronger focus

    Transcranial direct current stimulation (tDCS) is a form of noninvasive brain stimulation that has shown improved adult stroke outcomes. Applying tDCS in children with congenital hemiparesis has not yet been explored. The primary objective of this study was to explore the safety and feasibility of single-session tDCS through an adverse events profile and symptom assessment within a double-blind, randomized placebo-controlled preliminary study in children with congenital hemiparesis. A secondary objective was to assess the stability of hand and cognitive function. A double-blind, randomized placebo-controlled pretest/posttest/follow-up study was conducted. The study was conducted in a university pediatric research laboratory. Thirteen children, ages 7 to 18 years, with congenital hemiparesis participated. Adverse events/safety assessment and hand function were measured. Participants were randomly assigned to either an intervention group or a control group, with safety and functional assessments at pretest, at posttest on the same day, and at a 1-week follow-up session. An intervention of 10 minutes of 0.7 mA tDCS was applied to bilateral primary motor cortices. The tDCS intervention was considered safe if there was no individual decline of 25% or group decline of 2 standard deviations for motor evoked potentials (MEPs) and behavioral data and no report of adverse events. No major adverse events were found, including no seizures. Two participants did not complete the study due to lack of MEP and discomfort. For the 11 participants who completed the study, group differences in MEPs and behavioral data did not exceed 2 standard deviations in those who received the tDCS (n=5) and those in the control group (n=6). The study was completed without the need for stopping per medical monitor and biostatisticial analysis. A limitation of the study was the small sample size, with data available for 11 participants. Based on the results of this study, tDCS appears to be safe

    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.

    Reliable participation and sustained retention rates are crucial in longitudinal studies involving human subjects and biomaterials. Understanding the decision to enroll is an essential step to develop adequate strategies promoting long-term participation. Semi-structured interviews were implemented with newly recruited and long-term participants randomly drawn from two ongoing longitudinal studies with a biobank component in Germany. Iterative qualitative content analysis was applied to the transcribed interviews. Participants (n = 31) expressed their decision to enroll or remain in the study as the result of the complex interplay of individual factors, institutional cues, study-related features, and societal dynamics. Different forms of trust were identified as central within the elements used to explain participation and could be compared to Dibben, Morris, and Lean's dynamic model of interpersonal trust. Given these high levels of trust, an investigation of the morality of the trustful relationship at stake between participants and research(ers) is warranted. © The Author(s) 2016.

    Full Text Available Orientation: To encourage workers to participate in workplace HIV testing, some SouthAfrican automotive companies use lotteries. However, there is a lack of empirical evidence on how lottery incentives may influence employees’ workplace HIV counselling and testing behaviour. Research purpose: Determine whether workers intend to test for HIV only to win a lottery prize. Motivation for the study: The positive and also negative influences of lotteries on workers’ HIV testing behaviour need to be understood to avoid undue coercion in workplace HIV testing participation. Research design, approach and method: Post-test only quasi-experimental studies were conducted the day HIV testing and lotteries were announced to staff in four companies using a cross-sectional, self-administered survey that measured workers’ workplace HIV testing behaviour intentions. Intention to participate in workplace HIV counselling and testing was used as the main outcome of respondents’ behaviour and investigated via the statement: ‘If the company would organise its on-site Wellness Day tomorrow, I would go testing for HIV tomorrow’. In a first setting, two companies’ workers had to test for HIV to be entered in the lottery (n = 198. In the second setting, two other companies’ workers did not have to test to be entered in the lottery (n = 316. Chi-square tests were conducted to measure significant differences between the two conditions distinguishing between permanent and non-permanent staff. Main findings: No significant association was found between behaviour intention in the two settings for permanent workers’ workplace HIV testing intention ( χ2 = 1.145, p = 0.285, phi = -0.097. However, a significant association with a small effect size was found for non-permanent workers ( χ2 = 8.04, p = 0.005, phi = -0.279. Practical/managerial implications: Results show that lotteries to encourage workplace HIV testing are very likely to help workers ‘do the

    There is an urgent need to increase population levels of physical activity, particularly amongst those who are socio-economically disadvantaged. Multiple factors influence physical activity behaviour but the generalisability of current evidence to such 'hard-to-reach' population subgroups is limited by difficulties in recruiting them into studies. Also, rigorous qualitative studies of lay perceptions and perceptions of community leaders about public health efforts to increase physical activity are sparse. We sought to explore, within a socio-economically disadvantaged community, residents' and community leaders' perceptions of physical activity (PA) interventions and issues regarding their implementation, in order to improve understanding of needs, expectations, and social/environmental factors relevant to future interventions. Within an ongoing regeneration project (Connswater Community Greenway), in a socio-economically disadvantaged community in Belfast, we collaborated with a Community Development Agency to purposively sample leaders from public- and voluntary-sector community groups and residents. Individual semi-structured interviews were conducted with 12 leaders. Residents (n = 113), of both genders and a range of ages (14 to 86 years) participated in focus groups (n = 14) in local facilities. Interviews and focus groups were recorded, transcribed verbatim and analysed using a thematic framework. Three main themes were identified: awareness of PA interventions; factors contributing to intervention effectiveness; and barriers to participation in PA interventions. Participants reported awareness only of interventions in which they were involved directly, highlighting a need for better communications, both inter- and intra-sectoral, and with residents. Meaningful engagement of residents in planning/organisation, tailoring to local context, supporting volunteers, providing relevant resources and an 'exit strategy' were perceived as important factors

    While the majority of childhood cancer clinical trials are treatment related, additional optional research investigations may be carried out that do not directly impact on treatment. It is essential that these studies are conducted ethically and that the experiences of families participating in these studies are as positive as possible. A questionnaire study was carried out to investigate the key factors that influence why families choose to participate in optional nontherapeutic research studies, the level of understanding of the trials involved, and the experiences of participation. A total of 100 participants from six UK centers were studied; 77 parents, 10 patients >16 years, and 13 patients aged 8-15 years. Ninety-seven percent of parents and 90% of patients felt that information provided prior to study consent was of the right length, with 52% of parents and 65% of patients fully understanding the information provided. Seventy-four percent of parents participated in research studies in order to "do something important", while 74% of patients participated "to help medical staff". Encouragingly, <5% of participants felt that their clinical care would be negatively affected if they did not participate. Positive aspects of participation included a perception of increased attention from medical staff. Negative aspects included spending longer periods in hospital and the requirement for additional blood samples. Ninety-six percent of parents and 87% of patients would participate in future studies. The study provides an insight into the views of childhood cancer patients and their parents participating in nontherapeutic clinical research studies. Overwhelmingly, the findings suggest that participation is seen as a positive experience. © 2016 The Authors. Pediatric Blood & Cancer, published by Wiley Periodicals, Inc.

    2010-02-01

    This article reviewed and summarized the findings of previously published studies on the leisure activities of community elders over 55 years of age. A total of 17 related articles, published before 2008, were identified in the search of electronic databases, which included the Chinese Periodical Table of Contents Index Image System, CEPS, Medline and Ageline. Leisure activities measurements used in this study consisted of recoding activities either categorically or by frequency. The majority of research indicated that elderly engage in primarily static activities and that participation in leisure activities had positive effects on cognitive and psychological health. However, inconsistencies in results were found due to differences in measurement tools and sample populations used among studies, making it difficult to conduct a valid comparison of specific features of elderly leisure activities. Most current leisure activity studies utilize cross-sectional research methodologies with restricted topics, which result in limited applicability of research results. In conclusion, we suggest that future studies should develop instruments to assess leisure activities that correspond to local conditions identified through qualitative research. With such, researchers can study different age groups by applying relevant ageing theories to construct empirical data related to current elderly leisure activities.

  19. Participant experiences of mindfulness-based childbirth education: a qualitative study

    Full Text Available Abstract Background Childbirth is an important transitional life event, but one in which many women are dissatisfied stemming in part from a sense that labour is something that happens to them rather than with them. Promoting maternal satisfaction with childbirth means equipping women with communication and decision making skills that will enhance their ability to feel involved in their labour. Additionally, traditional antenatal education does not necessarily prepare expectant mothers and their birth support partner adequately for birth. Mindfulness-based interventions appear to hold promise in addressing these issues. Mindfulness-based Child Birth Education (MBCE was a pilot intervention combining skills-based antenatal education and Mindfulness Based Stress Reduction. Participant experiences of MBCE, both of expectant mothers and their birth support partners are the focus of this article. Methods A generic qualitative approach was utilised for this study. Pregnant women between 18 and 28 weeks gestation, over 18 years of age, nulliparous with singleton pregnancies and not taking medication for a diagnosed mental illness or taking illicit drugs were eligible to undertake the MBCE program which was run in a metropolitan city in Australia. Focus groups with 12 mothers and seven birth support partners were undertaken approximately four months after the completion of MBCE. Audio recordings of the groups were transcribed verbatim and analysed thematically using the method of constant comparison by all four authors independently and consensus on analysis and interpretation arrived at through team meetings. Results A sense of both ‘empowerment’ and ‘community’ were the essences of the experiences of MBCE both for mothers and their birth support partner and permeated the themes of ‘awakening my existing potential’ and ‘being in a community of like-minded parents’. Participants suggested that mindfulness techniques learned during MBCE

    This action research is an ongoing study which will last from 1991 to 1993. The main purpose of the study is to increase the participation of informal caregivers in the hospital care of elderly patients without decreasing the quality of care. The data reported here are from a pilot study. This study had three aims: (a) to test reliability and validity of the measure used, (b) to investigate the current participation of informal caregivers in the hospital care of elderly patients (aged over 75), and (c) to evaluate and compare the quality of care from both the patients' and the informal caregivers' point of view in three different hospitals. The measure of quality of care was developed on the basis of need theories, mainly those of Maslow and Alderfer. Patients and caregivers were also asked to rate the participation of the caregivers in the hospital care of elderly patients. Participation consisted of 18 activities of daily living. The pilot test with 18 elderly hospital patients and seven family members or significant others showed differences between the two groups in perception of care received. Statistically significant differences (P needs, psychic and spiritual needs and totals. The results supported earlier findings that elderly patients are satisfied with and do not criticize their care. The younger generation (i.e. their children) is more demanding and has precise perceptions about the care given. Relatives could be used more in planning, evaluation and even implementation of care; however, their current participation in patient hospital care is minimal.

    To investigate the association between fat and fiber intakes and the hypertriglyceridemic waist phenotype (HWP). Cross-sectional survey conducted from the baseline of Brazilian Longitudinal Study of Health Adult (ELSA-Brasil). Anthropometric measurements were conducted and the body mass index was calculated (BMI). Participants were classified according to the presence of HWP when waist circumference ≥ 102 and ≥ 88 cm, respectively, in men and women, and triglycerides ≥ 150 mg/dL. Fat and fiber intakes were assessed using a validated food frequency questionnaire, and socioeconomic, demographic and behavioral variables were collected through a questionnaire. The χ² test, Mann-Whitney and Poisson regression were performed with significance level of 5%. There was no association between fiber and fat intakes with HWP. A lower prevalence of HWP among men was observed (IRR = 0.959; 95%CI 0.948 - 0.969). A higher prevalence of HWP was observed in participants with low physical activity (OR = 1.039, 95%CI 1.021 - 1.057), smoking history (OR = 1.044, 95%CI 1.031 - 1.057), lower per capita income (IRR = 1.035; 95%CI 1.022 - 1.049) and obesity (OR = 1.32, 95%CI 1.305 - 1.341). Fat and fiber intakes were not associated with HWP. A higher prevalence of HWP was found in obese, but no association was found between intake of fat and fiber and phenotype.

    To develop statistical models of communicative participation development of preschool children and explore variations by level of function. This was a secondary analysis of data from a longitudinal study of preschool children with speech and language impairments (n=46 872; age range 18-67mo, mean age [SD] 41.76mo [11.92]; 67% male) accessing publicly funded services in Ontario, Canada. Two measures were used: Focus on the Outcomes of Communication Under Six (FOCUS), measuring changes in communicative participation skills, and the Communication Function Classification System (CFCS), classifying communicative function into one of five levels. We used mixed effects modeling to fit growth curves for children in each CFCS level. Models allowed for variation in initial FOCUS score at 18 months, rate of growth with age, and rate of acceleration/deceleration with age. Starting FOCUS score (18mo) varied inversely with CFCS level at entry to the program. Growth was initially rapid and then leveled off for children in Levels I to III. Growth was less rapid for children in Level IV, but leveled off, and was slow but continual for children in Level V. This work can help us to move beyond traditional impairment-based thinking and shows that children can make meaningful communicative changes regardless of their function. © 2017 Mac Keith Press.

    To study work participation of persons with hearing loss, and associations with hearing disabilities, self-reported workability, fatigue and work accommodation. Cross-sectional internet-based survey. A total of 10,679 persons with hearing loss within working-age were invited to answer the survey, where 3330 answered (35.6%). Degree of hearing loss was associated with low workability, fatigue and work place accommodation, while sick leave was associated with fatigue. Degree of hearing loss was positively associated with being unemployed (p part-time work (p < .01) (often combined with disability benefits) for women. Work place accommodation was more frequently provided among respondents working with sedentary postures, high seniority, long-term sick leave or low workability. Additional unfavourable sensory conditions were associated with decreased employment (p < .001) and workability, and an increase in sick leave (p < .01) and fatigue (p < .001). Hearing loss seemed to influence work participation factors negatively; particularly, for moderate hearing loss and for women, even though the degree of employment was high. A lack of work place accommodation when there was a need for such was found. This implies increased attentiveness towards individual needs concerning the experienced disability a hearing loss may produce. A more frequent use of hearing disability assessment is suggested.

    The use of medications for the treatment of dyslipidemia is relevant in the control of cardiovascular disease. This article aims to analyze the prevalence, the use and the participation of the public sector in the supply of medication for adults aged 40 years and above using pharmacotherapy for dyslipidemia control living in a city in the southern region of Brazil. A cross-sectional, population-based study was conducted. Household interviews were staged with 1180 individuals aged over 40 living in Cambé, State of Paraná, of which 967 took laboratory examinations. The prevalence of dyslipidemia was 69.2%, of which 16.1% were taking medication. Among individuals undergoing treatment for dyslipidemia, 22.2% had adequate test results. Lipid-lowering medication used were simvastatin (81.5%) and bezafibrate (6.5%), mainly obtained by direct payment to private pharmacies and drug stores (52.2%) and NHS services (33.6%). A high prevalence of dyslipidemias was observed in population terms, together with a low level of dyslipidemia control and low participation of the public sector regarding the supply of medication compared to acquisition through direct payment for medication in private pharmacies. These results suggest a limited range of public policy for control of dyslipidemia.

Some components of the metabolic syndrome (MetS coincide with the risk factors for sensorineural hearing loss (SNHL. To date, very few studies have examined the link between MetS and HL. The aim of the current study was to try to understand the potential association between MetS and HL.Methods: Using Iranian health surveys of professional drivers, we enrolled 11,114 individuals aged 20–60 years, whose main job is to operate a motor vehicle. We examined participants for the presence and absence of SNHL and the components of the MetS. Additionally, we investigated the relationship between MetS and the pure tone air conduction hearing thresholds of participants with SNHL, including low-frequency and high-frequency thresholds.Results: This cross-sectional study consisted of 11,114 participants: 3202 (28.81% diagnosed with MetS and 7911 (71.18% without and 2772 (24.94% with SNHL and 8432 (75.86% without. Participants with SNHL had a higher number of components of MetS (P<0.001 for all components.Conclusion: Our results demonstrated that an association possibly exists between different components of MetS (obesity, hypertension, hypertriglyceridemia, high fasting glucose levels, and waist circumference and SNHL in a population of West Azerbaijan drivers. Therefore, it is important to schedule periodic checkups for drivers to detect and avoid the increase in MetS components at an early stage in this population

  6. Automated Studies of Continuing Current in Lightning Flashes

    Science.gov (United States)

    Martinez-Claros, Jose

    Continuing current (CC) is a continuous luminosity in the lightning channel that lasts longer than 10 ms following a lightning return stroke to ground. Lightning flashes following CC are associated with direct damage to power lines and are thought to be responsible for causing lightning-induced forest fires. The development of an algorithm that automates continuing current detection by combining NLDN (National Lightning Detection Network) and LEFA (Langmuir Electric Field Array) datasets for CG flashes will be discussed. The algorithm was applied to thousands of cloud-to-ground (CG) flashes within 40 km of Langmuir Lab, New Mexico measured during the 2013 monsoon season. It counts the number of flashes in a single minute of data and the number of return strokes of an individual lightning flash; records the time and location of each return stroke; performs peak analysis on E-field data, and uses the slope of interstroke interval (ISI) E-field data fits to recognize whether continuing current (CC) exists within the interval. Following CC detection, duration and magnitude are measured. The longest observed C in 5588 flashes was 631 ms. The performance of the algorithm (vs. human judgement) was checked on 100 flashes. At best, the reported algorithm is "correct" 80% of the time, where correct means that multiple stations agree with each other and with a human on both the presence and duration of CC. Of the 100 flashes that were validated against human judgement, 62% were hybrid. Automated analysis detects the first but misses the second return stroke in many cases where the second return stroke is followed by long CC. This problem is also present in human interpretation of field change records.

    From an exposure of the Fermilab 15-foot bubble chamber to the Tevatron quadrupole triplet neutrino beam, we have determined the ratio of neutral-current (NC) to charged-current (CC) interactions to be 0.288±0.032 for events with visible hadron momentum above 10 GeV/c. The mean ν(bar ν) event energy is 150 (110) GeV, which is higher than that for any previous beam. This result agrees with those from previous experiments at lower energies. The NC/CC ratio is derived for a combined sample of ν and bar ν events. A value of 0.274±0.038 is obtained for the dominant ν component assuming bar ν NC/CC=0.39±0.08. For events with visible hadron momentum above 25 GeV/c, where the neutral hadron contamination remaining in the NC sample is assumed to be negligible, the combined NC/CC is 0.323±0.025 and the K 0 production rates are 0.375±0.064 per CC and 0.322±0.073 per NC event. The corresponding Λ rates are 0.161±0.030 per CC and 0.113±0.030 per NC event. The K 0 and Λ distributions of the fractional hadron energy variable z in NC events are consistent with those in CC events

Usually this electrolyte is a complexing agent and is necessary to increase the small differences between the species mobilities. A new column was developed, all made of acrylic, in a cylindrical shape. A set of experiments was carried out with the species Na + /K + , K + /Sm +3 , K + /Eu +3 and K + /Sm +3 /Eu +3 using the α-hydrox i-isobutyric acid o,01 M as the counter current electrolytic flux. From a synthetic mixture of 90% of samarium and 10% of europium was obtained the samarium ion in a purity better than 99,9% where the concentration of Eu was determined by the polarography technique. The potassium ion was used as a leading electrolyte. It was also measured the mobilities of the involved species in the α-HIBA medium. Two models are proposed, a stationary model and a dynamic one. A simulator of a simplified stationary model, prepared in FORTRAN language, was developed and tested toward experimental results. (author)

    To explore health, use of health services, 'core' information and reasons for non-participation amongst males. Gender may provide an explanation for non-participation in the healthcare system. A growing body of research suggests that males are less likely than females to seek help from health professionals for their problems. The current research had its beginnings with the low response rate in a prior voluntary survey and health examination for Finnish males born in 1961. Data triangulation among 28 non-respondent middle-aged males in Helsinki was used. The methods involved structured and in-depth interviews and health measurements to explore the views of these males concerning their health-related behaviours and use of health services. Non-respondent males seldom used healthcare services. Despite clinical risk factors (e.g. obesity and blood pressure) and various symptoms, males perceived their health status as good. Work was widely experienced as excessively demanding, causing insomnia and other stress symptoms. Males expressed sensitive messages when a session was ending and when the participant was close to the door and leaving the room. This 'core' information included major causes of concern, anxiety, fears and loneliness. This triangulation study showed that by using an in-depth interview as one research strategy, more sensitive 'feminist' expressions in health and ill-health were got by men. The results emphasise a male's self-perception of his masculinity that may have relevance to the health experience of the male population. Nurses and physicians need to pay special attention to the requirements of gender-specific healthcare to be most effective in the delivery of healthcare to males.

    Trauma-focused psychotherapies do not meet the needs of all veterans. Yoga shows some potential in reducing stress and perhaps even PTSD in veterans, although little is understood about the mechanisms of action. This study identifies preliminary correlates of change in PTSD and perceived stress for veterans participating in yoga. Nine veterans (seven males and two females) were recruited from an existing clinical yoga program and observed over 16 wk. Severity of PTSD symptoms (PCL-5) and perceived stress (PSS-10) were collected at baseline and weeks 4, 6, 8, and 16. Psychological flexibility (AAQ-II) and set-shifting (ratio of trail making test A to B) were collected at baseline and at week 6. Subjects attended yoga sessions freely, ranging from 1 to 23 classes over the 16 weeks. The Stanford University Institutional Review Board approved this research protocol. Self-reported PTSD symptoms significantly reduced while perceived stress did not. Lower baseline set-shifting predicted greater improvements in PTSD between baseline and 4 weeks; early improvements in set-shifting predicted overall reduction in PTSD. Greater psychological flexibility was associated with lower PTSD and perceived stress; more yoga practice, before and during the study, was associated with greater psychological flexibility. Other predictors were not supported. In a small uncontrolled sample, psychological flexibility and set-shifting predicted changes in PTSD symptoms in veterans participating in a clinical yoga program, which supports findings from prior research. Future research should include an active comparison group and record frequency of yoga practiced outside formal sessions.

    Several computer programs to aid in the design of eddy-current tests and probes have been written. The programs, written in Fortran, deal in various ways with the response to defects exhibited by four types of probes: the pancake probe, the reflection probe, the circumferential boreside probe, and the circumferential encircling probe. Programs are included which calculate the impedance or voltage change in a coil due to a defect, which calculate and plot the defect sensitivity factor of a coil, and which invert calculated or experimental readings to obtain the size of a defect. The theory upon which the programs are based is the Burrows point defect theory, and thus the calculations of the programs will be more accurate for small defects. 6 refs., 21 figs

    The activities of a coordinating center pharmacy (CCP) supporting a multicenter, international clinical trial are described. Serving in a research support role comparable to that of a commercial clinical trial supply company, a CCP within the Johns Hopkins Hospital Investigational Drug Service (JHH IDS) uses its management expertise and infrastructure to support multicenter trials, such as the recently completed Clot Lysis: Evaluating Accelerated Resolution of Intraventricular Hemorrhage, Phase III (CLEAR III) trial. The role of the CCP staff in supporting the CLEAR III trial was overall investigational product (IP) management through coordination of IP-related operations to ensure high-quality care for study participants at study sites in the United States and abroad. For the CLEAR III trial, the CCP coordinated IP supply activities; provided education to site pharmacists; developed study-specific documents, including pharmacy manuals; communicated with trial stakeholders, including third-party IP distributors; monitored treatment assignments; and performed quality assurance monitoring to ensure compliance with institutional, state, federal, and international regulations regarding IP procurement and storage. Acting as a CCP for a multicenter international study poses a number of operational challenges while providing opportunities for the CCP to contribute to research of global importance and enrich the skill sets of its personnel. The development and implementation of the CCP at JHH IDS for the CLEAR III trial included several responsibilities, such as IP supply management, communication, and database, regulatory, and finance management.

  19. Studies of current-perpendicular-to-plane magnetoresistance (CPP-MR) and current-induced magnetization switching (CIMS)

    2005-08-01

    We present two CPP-MR studies of spin-valves based upon ferromagnetic/nonmagnetic/ferromagnetic (F/N/F) trilayers. We measure the spin-diffusion lengths of N = Pd, Pt, and Au at 4.2K, and both the specific resistances (sample area A times resistance R) and spin-memory-loss of N/Cu interfaces. Pd, Pt and Au are of special device interest because they give perpendicular anisotropy when sandwiching very thin Co layers. Comparing our spin-memory-loss data at Pd/Cu and Pt/Cu interfaces with older data for Nb/Cu and W/Cu gives insight into the importance of spin-orbit coupling in producing such loss. We reproduce and extend prior studies by Eid of 'magnetic activity' at the interface of Co and N-metals (or combinations of N-metals), when the other side of the N-metal contacts a superconductor (S). Our data suggest that magnetic activity may require strong spin-flipping at the N/S interface. We present five studies of a new phenomenon, CIMS, in F1/N/F2 trilayers, with F1 a thick 'polarizing' layer and F2 a thin 'switching' layer. In all prior studies of CIMS, positive current caused the magnetization of F2 to switch from parallel (P) to anti-parallel (AP) to that of F1- 'normal' switching. By judicious addition of impurities to F-metals, we are able to controllably produce both 'normal' and 'inverse' switching- where positive current switches the magnetization of F2 from AP to P to that of F1. In the samples studied, whether the switching is normal or inverse is set by the 'net polarization' produced by F1 and is independent of the properties of F2. As scattering in the bulk of F1 and F2 is essential to producing our results, these results cannot be described by ballistic models, which allow scattering only at interfaces. Most CIMS experiments use Cu as the N-layer due to its low resistivity and long spin-diffusion length. We show that Ag and Au have low enough resistivities and long enough spin-diffusion lengths to be useful alternatives to Cu for some devices. While

    Adequate participation of children and adolescents in their healthcare is a value underlined by several professional associations. However, little guidance exists as to how this principle can be successfully translated into practice. A total of 52 semi-structured interviews were carried out with 19 parents, 17 children, and 16 pediatric oncologists. Questions pertained to participants' experiences with patient participation in communication and decision-making. Applied thematic analysis was used to identify themes with regard to participation. Three main themes were identified: (a) modes of participation that captured the different ways in which children and adolescents were involved in their healthcare; (b) regulating participation, that is, regulatory mechanisms that allowed children, parents, and oncologists to adapt patient involvement in communication and decision-making; and (c) other factors that influenced patient participation. This last theme included aspects that had an overall impact on how children participated. Patient participation in pediatrics is a complex issue and physicians face considerable challenges in facilitating adequate involvement of children and adolescents in this setting. Nonetheless, they occupy a central role in creating room for choice and guiding parents in involving their child. Adequate training of professionals to successfully translate the principle of patient participation into practice is required. •Adequate participation of pediatric patients in communication and decision-making is recommended by professional guidelines but little guidance exists as to how to translate it into practice. What is New: •The strategies used by physicians, parents, and patients to achieve participation are complex and serve to both enable and restrict children's and adolescents' involvement.

    2016-06-01

    Full Text Available This paper presents a comparison of voltage mode control (VMC and two current mode control (CMC methods of noninverting buck-boost converter. The converter control-to-output transfer function, line-to-output transfer function and the output impedance are obtained for all methods by averaging converter equations over one switching period and applying small-signal linearization. The obtained results are required for the design procedure of feedback compensator to keep a system stable and robust. A comparative study of VMC, peak current mode control (PCMC and dual-current mode control (DCMC is performed. Performance evaluation of the closed-loop system with obtained compensator between these methods is performed via numerical simulations.

    Recruitment, assessment, and longitudinal monitoring of participants for neuroscience studies and clinical trials limit the development of new treatments. Widespread Internet use allows data capture from participants in an unsupervised setting. The Brain Health Registry, a website and online registry, collects data from participants and their study partners. The Brain Health Registry obtains self and study partner report questionnaires and neuropsychological data, including the Cogstate Brief Battery, Lumos Labs Neurocognitive Performance Test, and MemTrax Memory Test. Participants provide informed consent before participation. Baseline and longitudinal data were obtained from nearly 57,000 and 28,000 participants, respectively. Over 18,800 participants were referred to, and nearly 1800 were enrolled in, clinical Alzheimer's disease and aging studies, including five observational studies and seven intervention trials. Online assessments of participants and study partners provide useful information at relatively low cost for neuroscience studies and clinical trials and may ultimately be used in routine clinical practice.

    Abstract Background: Feeding infants unscreened, raw human milk from a source other than the mother may pose health risks. The objectives of the Moms2Moms Study were to estimate the proportions of mothers who were aware of breastmilk sharing, considered sharing, and shared milk and to identify associated maternal and child characteristics. Subjects and Methods: All eligible women (n=813) who delivered at The Ohio State University Wexner Medical Center (Columbus, OH) and did not indicate an intention to exclusively “bottle feed” were asked to participate in this cohort by completing a postal questionnaire at 12 months postpartum (499 [61%] responded). Women who shared milk participated in a follow-up interview. Results: Awareness of milk sharing was high (77%) and positively associated with socioeconomic status, age, non-Hispanic white race, having fed one's infant at the breast, and reporting no difficulty making enough milk. Twenty-five percent considered sharing. Primiparous women (odds ratio [OR]=2.12; 95% confidence interval [CI] 1.02, 4.62) and those who delivered preterm (OR=3.27; 95% CI 1.38, 7.30) were more likely to consider feeding milk from another mother. Women with public/no insurance (OR=0.52; 95% CI 0.27, 0.97) were less likely to consider providing milk for someone else; highly educated women were more likely (OR=1.90; 95% CI 1.12, 3.32). Almost 4% of women shared milk and did so among friends or relatives or had a preterm infant who received screened and pasteurized donor milk. Conclusions: Sharing milk among friends and relatives is occurring. Many women are aware of milk sharing and have considered it. PMID:25007386

    The aim of this study was to determine opportunities for students and trainees to obtain an MPH or MBA degree during either medical school or radiology residency and to determine the prevalence of such degree possession by chairpersons in radiology. All allopathic medical schools in the United States were surveyed to chart the number of MD/MPH and MD/MBA degree programs available to students. Program directors were contacted to assess the number of MPH or MBA courses of study administratively related to their residencies. Also, an e-mail survey was sent to all members of the Society of Chairs of Academic Radiology Departments inquiring whether each chairperson had earned an additional degree. Currently, 81 allopathic medical schools in the United States offer MD/MPH degrees, and 52 offer MD/MBA degrees. Six residencies provide access to MPH programs, and 3 residencies provide the opportunity to pursue an MBA in conjunction with residency. Of these, only 1 MPH program and no MBA programs had trainees enrolled at present. Twenty-six percent of the chairpersons surveyed possessed advanced degrees other than MDs. There has been rapid growth in the number of MD/MPH and MD/MBA programs available to medical students. However, there is a scarcity of similar programs accessible to trainees during or just after residency training. To assist motivated radiologists interested in leading our profession, opportunities should expand both in formal degree-granting programs and through certificate-sanctioned course series to address relevant issues of leadership and management pertinent to our specialty.

    Full Text Available It is anticipated that the urban population in developing countries increases more than double from 2000 to 2030. This rapid population transformation to cities will be difficult. Therefore, the municipal administration will be involved in numerous challenges in cities. For this purpose, social capital as a bottom-up planning is one of the appropriate ways of management and dealing with these challenges. The aim of this study was to measure the social capital in four aspects of knowledge, participation, social cohesion, and trust in Zahedan. The research method of this research is descriptive-analytic in an applied type. Library studies and surveying (questionnaire were used to collect the required data. The questions in this survey were designed based on four indicators of social capital. The statistical population of the present study is 575,116 people residing in Zahedan in 2011. One sample T- test was used for calculations. The results of the analysis show that the social capital criteria in the city of Zahedan are undesirable in all four criteria.

    A prior meta-analysis revealed that higher doses of transcranial direct current stimulation (tDCS) have a better post-stroke upper-extremity motor recovery. While this finding suggests that currents greater than the typically used 2 mA may be more efficacious, the safety and tolerability of higher currents have not been assessed in stroke patients. We aim to assess the safety and tolerability of single session of up to 4 mA in stroke patients. We adapted a traditional 3 + 3 study design with a current escalation schedule of 1»2»2.5»3»3.5»4 mA for this tDCS safety study. We administered one 30-min session of bihemispheric montage tDCS and simultaneous customary occupational therapy to patients with first-ever ischemic stroke. We assessed safety with pre-defined stopping rules and investigated tolerability through a questionnaire. Additionally, we monitored body resistance and skin temperature in real-time at the electrode contact site. Eighteen patients completed the study. The current was escalated to 4 mA without meeting the pre-defined stopping rules or causing any major safety concern. 50% of patients experienced transient skin redness without injury. No rise in temperature (range 26°C-35 °C) was noted and skin barrier function remained intact (i.e. body resistance >1 kΩ). Our phase I safety study supports that single session of bihemispheric tDCS with current up to 4 mA is safe and tolerable in stroke patients. A phase II study to further test the safety and preliminary efficacy with multi-session tDCS at 4 mA (as compared with lower current and sham stimulation) is a logical next step.

    Full Text Available Parkinson's disease (PD was characterized by late-onset, progressive dopamine neuron loss and movement disorders. The progresses of PD affected the neural function and integrity. To date, most researches had largely addressed the dopamine replacement therapies, but the appearance of L-dopa-induced dyskinesia hampered the use of the drug. And the mechanism of PD is so complicated that it's hard to solve the problem by just add drugs. Researchers began to focus on the genetic underpinnings of Parkinson's disease, searching for new method that may affect the neurodegeneration processes in it. In this paper, we reviewed current delivery methods used in gene therapies for PD, we also summarized the primary target of the gene therapy in the treatment of PD, such like neurotrophic factor (for regeneration, the synthesis of neurotransmitter (for prolong the duration of L-dopa, and the potential proteins that might be a target to modulate via gene therapy. Finally, we discussed RNA interference therapies used in Parkinson's disease, it might act as a new class of drug. We mainly focus on the efficiency and tooling features of different gene therapies in the treatment of PD.

    Full Text Available Abstract Background Increased awareness amongst large population groups is a major determinant for the prevention of diabetes and its complications as well as related metabolic disorders. Knowledge and attitude are the principal markers of awareness that need to be studied in various population groups in specific racial and cultural contexts. The present study was undertaken to explore knowledge, attitude and practice (KAP regarding -diabetes mellitus (DM among nondiabetic (nonDM and type 2 diabetes mellitus (T2DM patients in Bangladesh. Methods A cross-sectional study was conducted among 18,697 adults (aged 18 years and above; 7796 male and 10,901 female; 6780 nonDM and 11,917 T2DM selected purposively from the OPD of 19 healthcare centres in and around Dhaka and in northern parts of Bangladesh. KAP were assessed by a pre-structured, interviewer-administered questionnaire and categorised using predefined scores of poor (mean + 1 SD. Univariate and bivariate statistical analysis were done as appropriate. Multivariate linear regression was done to examine the association between diabetes related KAP and other covariates. Results The mean (±SD age (years of all the study participants was 46 ± 14, mean BMI 24.4 ± 4.1 and mean waist-hip ratio (WHR was 0.93 ± 0.07. The proportion of poor, average and good knowledge scores among T2DM subjects were 17%, 68% and 15% respectively. The corresponding values for attitude score were 23%, 67% and 10% respectively. The KAP regarding diabetes was found to be better among people who were living with diabetes compared to their counterparts. DM males showed better knowledge and practice regarding diabetes, compared to nonDM counterparts (M ± SD; 44.18 ± 16.13 vs 40.88 ± 15.62, p = <0.001; 66.00 ± 29.68 vs 64.21 ± 31.79, p < 0.001, respectively. Females showed better attitude score compared to males. Overall KAP were found to be significantly higher (p < 0.001 in middle aged (31

    Taylor, F. W.; McCleese, D. J.; Schofield, J. T.; Calcutt, S. B.; Moroz, V. I.

    A systematic and detailed experimental study of the Martian atmosphere remains to be carried out, despite many decades of intense interest in the nature of the Martian climate system, its interactions, variability and long-term stability. Such a study is planned by the 2005 Mars Reconnaissance Orbiter, using limb-scanning infrared radiometric techniques similar to those used to study trace species in the terrestrial stratosphere. For Mars, the objectives are temperature, humidity, dust and condensate abundances with high vertical resolution and global coverage in the 0 to 80 km height range. The paper will discuss the experiment and its methodology and expectations for the results.

    In this pilot study within the Pretest 2 phase of the German National Cohort, we aimed to (1) test the hypothesis that distance and duration of travel to a study centre may affect participation rates and participants' satisfaction and (2) to obtain data that would help to select recruitment areas around the study centre Hannover with the greatest projected participation rate for the main study. Mixed urban/suburban environment in Northern Germany with approximately 600,000 inhabitants. 4 recruitment areas with divergent estimated mean distances (range, 7-40 km) and duration of travel to the study centre Hannover were selected. 1050 men and women (ratio, 1:1), aged 20-69 years, were randomly selected from the population registries of the 4 recruitment areas and invited by mail to participate in the Pretest 2 study programme at the study centre Hannover, covering a variety of questionnaire-based and physical assessments. 166 individuals participated (16%). All 166 participants completed a travel questionnaire containing 5 items relating to travel duration and satisfaction, amounting to a participation rate of 100% in the questionnaire-based part of the study. Participation rates in the Pretest 2 programme at the study centre Hannover by area ranged from 11% (area farthest from the study centre, estimated median distance 38 km) to 18% (nearest area, 2 km). The odds of non-participation were highest in the area farthest from the study centre (adjusted OR 2.06; p=0.01; CI 1.28 to 3.32). Nonetheless, 97% of participants were satisfied with travel duration. Increasing distance was associated with a lower participation rate. However, acceptance of duration of travel was high, irrespective of distance or duration. Thus, recruiting in farther away locations may select individuals with a greater frustration tolerance for travel to the study centre, perhaps due to a greater interest in participating in health-oriented studies and thus different health-related behaviour

    Background Patient safety experts have postulated that increasing patient participation in communications during patient handovers will improve the quality of patient transitions, and that this may reduce hospital readmissions. Choosing strategies that enhance patient safety through improved handovers requires better understanding of patient experiences and preferences for participation. Objective The aim of this paper is to explore the patients’ experiences and perspectives related to the handovers between their primary care providers and the inpatient hospital. Methods A qualitative secondary analysis was performed, based on individual and focus group patient interviews with 90 patients in five European countries. Results The analysis revealed three themes: patient positioning in the handover process; prerequisites for patient participation and patient preferences for the handover process. Patients’ participation ranged from being the key actor, to sharing the responsibility with healthcare professional(s), to being passive participants. For active participation patients required both personal and social resources as well as prerequisites such as information and respect. Some patients preferred to be the key actor in charge; others preferred their healthcare professionals to be the key actors in the handover. Conclusions Patients’ participation is related to the healthcare system, the activity of healthcare professionals’ and patients’ capacity for participation. Patients prefer a handover process where the responsibility is clear and unambiguous. Healthcare organisations need a clear and well-considered system of responsibility for handover processes, that takes into account the individual patient's need of clarity, and support in relation to his/hers own recourses.

    Lower participation rates of ethnic minorities in health research studies and potential participation barriers are commonly reported. Four semi-structured focus groups of individuals with Turkish migration backgrounds living in Germany were conducted to identify potential participation barriers. Documented statements and superscripted presentation cards by the participants were evaluated with a qualitative content analysis. The following eight potential reasons for the lower participation rates were identified: role of women, lack of knowledge, lack of interest, German-Turkish interactions, mistrust, anxiety, data privacy protection and benefits of the study. Additionally, the following recruitment strategies to enhance participation rates were found: public relations, especially word-of-mouth promotion and contacting Turkish key figures, (non-) tangible incentives and trust building through transparent communication of the project and its conditions. The findings provide a wide range of potential participation barriers and implications that should be considered to enhance the participation rates of minority populations. The willingness to participate in health research studies can be increased through particular efforts, which should be tailored to the recruitment of the underrepresented target population.

    To explore the perceived benefits for patients and family members of psychoeducational family intervention following a first episode of psychosis. A qualitative exploratory study using data from interviews with 12 patients and 14 family members who participated in a psychoeducational multi- or single-family treatment programme. Semi-structured interviews were digitally recorded and transcribed verbatim with slight modifications, after which they were analysed by systematic text condensation. Patients and family members reported benefits that could be classified in five categories: (i) developing insight and acceptance requires understanding of the fact that the patient has an illness, and recognizing the need for support; (ii) recognizing warning signs requires an understanding of early signs of deterioration in the patient; (iii) improving communication skills is linked to new understanding and better communication both within the family and in groups; (iv) Learning to plan and solve problems requires the ability to solve problems in new ways; (v) becoming more independent requires patients to take responsibility for their own life. The study suggests that developing insight and acceptance, learning about warning signs, improving communications skills, learning to plan and solve problems, and becoming more independent are perceived as benefits of a psychoeducational family intervention. © 2014 Wiley Publishing Asia Pty Ltd.

    2013-01-01

    Background Occupational burnout is associated with severe negative health effects. While stress management programs proved to have a positive influence on the well-being of patients suffering from burnout, it remains unclear whether aerobic exercise alleviates burnout severity and other parameters related to occupational burnout. Therefore, the main purpose of this study was to pilot-test the potential outcomes of a 12-week exercise training to generate hypotheses for future larger scale studies. Methods The sample consisted of 12 male participants scoring high on the MBI emotional exhaustion and depersonalization subscales. The training program took place in a private fitness center with a 17.5 kcal/kg minimum requirement of weekly energy expenditure. Results The key findings are that increased exercise reduced overall perceived stress as well as symptoms of burnout and depression. The magnitude of the effects was large, revealing changes of substantial practical relevance. Additionally, profiles of mood states improved considerably after single exercise sessions with a marked shift towards an iceberg profile. Conclusion Among burnout patients, the findings provide preliminary evidence that exercise has the potential to reduce stress and prevent the development of a deeper depression. This has important health implications given that burnout is considered an antecedent of depressive disorders. Trial registration ClinicalTrials.gov Identifier: ISRNCT01575743 PMID:23497731

    Each of the six case studies documents public participation in Federal and/or state governmental decisions related to energy facility siting. Four of the cases involved decisions on specific facilities at specific sites, namely: (1) various state and federal licensing procedures for the Seabrook, New Hampshire nuclear facility; (2) the Maine Environmental Improvement Commission's denial of a permit for an oil refinery on Sears Island in Penobscot Bay; (3) the Atomic Energy Commission's amendment to the license for the Big Rock Point, Michigan, nuclear reactor to allow an increased level of plutonium-enriched fuel use; (4) the AEC's review, arising from disclosure of a geological fault, of the North Anna River, Virginia, nuclear facility. A fifth case documents a series of public meetings conducted in Pennsylvania by the Governor's Energy Council to consider the energy park concept. The sixth study was a narrative history and analysis of RM-50-1, a rulemaking proceeding conducted by the AEC in 1972 and 73 on emergency core cooling system operating standards.

    To identify and prioritise targets for injury prevention efforts, injury incidence studies are widely reported. The accuracy and consistency in calculation and reporting of injury incidence is crucial. Many individuals experience more than one injury but multiple injuries are not consistently reported in sport injury incidence studies. The aim of this systematic review was to evaluate current practice of how multiple injuries within individuals have been defined and reported in prospective, long-term, injury studies in team ball sports. A systematic search of three online databases for articles published before 2016. Publications were included if (1) they collected prospective data on musculoskeletal injuries in individual participants; (2) the study duration was >1 consecutive calendar year/season; and (3) individuals were the unit of analysis. Key study features were summarised, including definitions of injury, how multiple individual injuries were reported and results relating to multiple injuries. Of the 71 publications included, half did not specifically indicate multiple individual injuries; those that did were largely limited to reporting recurrent injuries. Eight studies reported the number/proportion of athletes with more than one injury, and 11 studies presented the mean/number of injuries per athlete. Despite it being relatively common to collect data on individuals across more than one season, the reporting of multiple injuries within individuals is much more limited. Ultimately, better addressing of multiple injuries will improve the accuracy of injury incidence studies and enable more precise targeting and monitoring of the effectiveness of preventive interventions.

    Nutritional deficiencies are known to be associated with hair loss; however, the exact prevalence is not known. The aim of this study is to evaluate the prevalence of nutritional deficiencies in participants with hair loss. In this cross-sectional study, 100 enrolled participants were divided into telogen effluvium (TE), male-pattern hair loss (MPHL), and female-pattern hair loss (FPHL) based on the type of hair loss. All participants underwent laboratory estimation for micronutrients and amino acid levels. Participants with hair loss showed varied amino acid and micronutrient deficiencies across all types of hair loss. Nutritional status did not vary much between the types of hair loss. Among the essential amino acids, histidine deficiency was seen in >90% of participants with androgenic alopecia and 77.78% of participants with TE while leucine deficiency was seen 98.15% of participants with TE and 100% with FPHL. Valine deficiency was also very common across alopecia subtypes. Among the nonessential amino acids, alanine deficiency was observed in 91.67% FPHL, 91.18% MPHL, and 90.74% TE. Cysteine deficiency was present in 55.58% and 50% of participants with MPHL and TE, respectively. A relatively higher proportion of participants with TE had iron deficiency compared to androgenic alopecia ( P = 0.069). Zinc deficiency was seen in 11.76% of participants with MPHL while copper deficiency was seen in 29.41% and 31.48% of participants with MPHL and TE, respectively. Nutritional deficiency is a common problem in participants with hair loss irrespective of the type of alopecia. The findings of our study suggest need for identification and correction of nutritional deficiencies in patients with hair loss.

    The World Health Organisation has designed a pregnancy registry to investigate the effect of maternal drug use on pregnancy outcomes in resource-limited settings. In this sentinel surveillance system, detailed health and drug use data are prospectively collected from the first antenatal clinic visit until delivery. Over and above other clinical records, the registry relies on accurate participant reports about the drugs they use. Qualitative methods were incorporated into a pilot registry study during 2010 and 2011 to examine barriers to women reporting these drugs and other exposures at antenatal clinics, and how they might be overcome. Twenty-seven focus group discussions were conducted in Ghana, Kenya and Uganda with a total of 208 women either enrolled in the registry or from its source communities. A question guide was designed to uncover the types of exposure data under- or inaccurately reported at antenatal clinics, the underlying reasons, and how women prefer to be asked questions. Transcripts were analysed thematically. Women said it was important for them to report everything they had used during pregnancy. However, they expressed reservations about revealing their consumption of traditional, over-the-counter medicines and alcohol to antenatal staff because of anticipated negative reactions. Some enrolled participants' improved relationship with registry staff facilitated information sharing and the registry tools helped overcome problems with recall and naming of medicines. Decisions about where women sought care, which influenced medicines used and antenatal clinic attendance, were influenced by pressure within and outside of the formal healthcare system to conform to conflicting behaviours. Conversations also reflected women's responsibilities for producing a healthy baby. Women in this study commonly take traditional medicines in pregnancy, and to a lesser extent over-the-counter medicines and alcohol. The World Health Organisation pregnancy registry

    The objective of the present study was to determine emergency physicians' training, experience and perceptions as expert witnesses. Emergency physicians of an adult tertiary referral and teaching hospital participated in a pilot survey regarding their experiences in report writing and in court as expert witnesses. The 28-item survey also examined the amount of formalized forensic medical teaching that emergency physicians had received during their training. Of the participants, 41% (95% CI 21.6-64.1; 7/17) had never received any undergraduate or postgraduate training in forensic medicine, 11/17 (65%, 95% CI 41.2-82.8) had provided a written expert opinion for court, and 12/17 (71%, 95% CI 46.6-87.0) had attended court as an expert witness. All participants considered themselves 'skilled in attending an emergency resuscitation', whereas 3/13 (23%, 95% CI 7.5-50.9) considered themselves 'skilled in attending a courtroom trial'. Nearly 90% (95% CI 64.7-98.0; 15/17) thought that medical evidence training should be a requirement of emergency speciality training. The most commonly preferred forms of medical evidence training were mock court sessions (76%, 95% CI 52.2-91.0; 13/17) and forensic workshops (76%, 95% CI 52.2-91.0; 13/17). From 10 non-technical skills required of an EP, 'appearing in court as an expert witness' was perceived to be the second most difficult skill by most respondents. Emergency physicians in this pilot study have limited training for the role of expert witness and see it as one of the most difficult non-technical skills they have to perform. Further research is required regarding the current and future scope of forensic training.

    This study investigated osteoporosis management trends from 1998 to 2006 among 808 primary care physicians involved in the US-based NORA (National Osteoporosis Risk Assessment) study. These results suggest some significant improvements in osteoporosis management over the past eight years. The purpose of this study was to investigate osteoporosis management trends among a large cohort of primary care physicians (PCPs) involved in the US-based NORA (National Osteoporosis Risk Assessment) study. In 2006, we undertook a resurvey of the 2,836 NORA PCPs who completed a baseline survey in 1998. Of the 2,199 PCPs for whom we had current contact information and who were still practicing, we collected usable surveys from 808 (37% response rate). From 1998 to 2006, more than double the percentage of NORA PCPs reported using BMDs "often" (35% vs. 87%). There was a doubling of the percentage of NORA PCPs who reported that a T-score of NORA PCPs who reported using bone turnover markers to screen, diagnosis, or monitor osteoporosis almost tripled (19% vs. 55%). The percentage of patients prescribed or recommended hormone therapy dropped sixfold (67% to 11%), and the percentage of patients prescribed bisphosphonates increased fourfold from 15% to 59%. These results suggest some significant improvements in osteoporosis management over the past eight years.

    The rapid increase in mobile phone use in young people has generated concern about possible health effects of exposure to radiofrequency (RF) fields. Mobi-Kids, an international study coordinated by CREAL Barcelona, is underway in 15 countries to assess potential effects of childhood and adolescent exposure to electromagnetic fields (EMF) from mobile communications technology (RF and extremely low frequency (ELF) fields) on brain tumour risk. The study aims to recruit over 2,000 cases of brain tumours aged 10 to 24 years and their respective controls (300 cases and 600 controls from Spain). The project builds upon the methodological experience of the INTERPHONE study. Hospital based controls are being selected to reduce potential selection bias related to low response rates of population-based controls, validation of questionnaire responses with recross from network operators will allow characterization of possible recall errors. Extensive work has gone into characterising and modelling ELF and RF exposure from different types of mobile and cordless phones, from different communication systems, and from other environmental sources of EMF. The study will address a public health problem of increasing importance in Spain and provide information on potential health risks from mobile telephone use as well as from EMF in general.

    While medical research ethics guidelines frame participants as individual and autonomous, anthropologists emphasize the relational nature of health research participation. I analyze interviews with Mexican male HPV study participants and their wives to examine how research participants themselves focus on relationships when imagining research-related benefits. I argue that couples incorporated the local trope of the Mexican citizenry as a biologically homogeneous national body, which individual members help or harm through their gendered health behavior to understand these benefits. I use the concept of "ethical intercorporeality" to discuss spouses' understandings of themselves as parts of bio-social wholes-the couple, family, and society-that they believed men's research participation could aid both physically and socially. This finding extends the insight that focusing on relationships rather than individuals is necessary for understanding the consequences of medical research by showing how participants themselves might apply this perspective in context-specific ways. © 2016 by the American Anthropological Association.

    Barriers to recruitment for research on mental illness include participant distrust of researchers and social stigma. Though these issues may be acutely important in perinatal mental health research, they remain unexplored in this context. In order to inform strategies to more fully engage women in perinatal mental health research, we explored the motivations and experiences of women with a history of major depressive disorder who participated in a prospective longitudinal research study on postpartum depression (PPD). Sixteen women with a history of depression who had either completed or recently made a decision about participation in a longitudinal research study about PPD were interviewed by telephone. Qualitative, semi-structured interviews explored participants' decision-making about, and experiences of, participation. Interviews were audio-recorded, transcribed, and qualitatively analyzed using elements of grounded theory methodology. Follow-up interviews were conducted with four participants to refine and clarify preliminary results. Foundational elements necessary for women to consider participating in PPD research included personal acceptance of illness and trust in the research team/institution. Other main motivators included perceived personal relevance, anticipated benefits (including access to support/resources, learning opportunities, and improved self-worth), altruism, and accessible study procedures. Our data suggest that participating in perinatal mental health research may help women make meaning of their mental illness experience and is perceived as providing support. The findings-particularly around the importance of participant-researcher rapport and accessibility of study design-may inform strategies that improve participation rates, decrease attrition, and maximize participant benefits in perinatal mental health research.

    1984-12-01

    The efficiency of a helmet-type powered air-purifying respirator was studied in the work environment of an underground uranium mine. Workplace protection factors (WPF) were measured, using approximately 30-minute air sampling periods and repeated sampling throughout the work shifts for six miners during three shifts each. The WPF of the modified Racal AH-5 helmet was 17.8 (geometric mean) with new filters in the respirator; the WPF dropped to 5.3 when four-day-old filters were used. The WPF results were lognormally distributed. The test population appeared to be a homogeneous set: there was no significant difference in the mean WPFs of individual test subjects. The study could not resolve any effect of elapsed time within the work shift or of ambient Working Level on the WPF. The actual use levels and the problems associated with respirator use were studied at the same time, principally via a user survey. The respirators have a high level of acceptance among the user population of underground uranium miners and 72.5 percent of the 207 survey respondents stated six or more hours use with the visor in the correct 'down' position per shift

  18. The current status of glass leaching studies in France

    International Nuclear Information System (INIS)

    Laude, F.

    1983-11-01

    Glass has been selected in France as the material used to confine the activity of fission product solutions, and a continuous vitrification process has been developed at the Marcoule Vitrification Facility (AVM), the first industrial plant. Borosilicate glass was chosen in various compositions for its properties: it is a homogeneous, non-porous material that incorporates appreciable quantities of most of the fission product oxides, and is only alterable at the surface interface layer. Glass thus constitutes the primary radioactivity containment barrier, and it is essential to determine its long-term behavior. Water constitutes the principal hazard during temporary or definitive storage of the glass blocks. Two types of inherent material properties are studied from the standpoint of glass stability under leaching conditions: - chemical durability; - radioactive containability with regard to the various radionuclides, fission products and especially the actinides. Durability tests are carried out in SOXHLET devices and the alteration rates are measured by the weight loss. The containability is measured by the leach rate, i.e. by the rate of activity loss into the water. Leaching tests are conducted for several major objectives: - selection of glass compositions (leach rates); - leaching mechanism studies (hydrolyzed layer characteristics, effects of temperature, pressure, pH, etc.); - long-term behavior studies (glass specimens doped with alpha-emitters); - simulation of geological repository environments [fr

  19. Individual participant data meta-analysis of prognostic factor studies: state of the art?

    Full Text Available Abstract Background Prognostic factors are associated with the risk of a subsequent outcome in people with a given disease or health condition. Meta-analysis using individual participant data (IPD, where the raw data are synthesised from multiple studies, has been championed as the gold-standard for synthesising prognostic factor studies. We assessed the feasibility and conduct of this approach. Methods A systematic review to identify published IPD meta-analyses of prognostic factors studies, followed by detailed assessment of a random sample of 20 articles published from 2006. Six of these 20 articles were from the IMPACT (International Mission for Prognosis and Analysis of Clinical Trials in traumatic brain injury collaboration, for which additional information was also used from simultaneously published companion papers. Results Forty-eight published IPD meta-analyses of prognostic factors were identified up to March 2009. Only three were published before 2000 but thereafter a median of four articles exist per year, with traumatic brain injury the most active research field. Availability of IPD offered many advantages, such as checking modelling assumptions; analysing variables on their continuous scale with the possibility of assessing for non-linear relationships; and obtaining results adjusted for other variables. However, researchers also faced many challenges, such as large cost and time required to obtain and clean IPD; unavailable IPD for some studies; different sets of prognostic factors in each study; and variability in study methods of measurement. The IMPACT initiative is a leading example, and had generally strong design, methodological and statistical standards. Elsewhere, standards are not always as high and improvements in the conduct of IPD meta-analyses of prognostic factor studies are often needed; in particular, continuous variables are often categorised without reason; publication bias and availability bias are rarely

    Informed consent is a key element of ethical clinical research. Addicted population may be at risk for impaired consent capacity. However, very little research has focused on their comprehension of consent forms. The aim of this study is to assess the capacity of addicted individuals to provide consent to research. 53 subjects with DSM-5 diagnoses of a Substance Use Disorder (SUD) and 50 non psychiatric comparison subjects (NPCs) participated in the survey from December 2014 to March 2015. This cross-sectional study was carried out at a community-based Outpatient Treatment Center and at an urban-located Health Centre in Spain. A binary judgment of capacity/incapacity was made guided by the MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR) and a clinical interview. Demographics and clinical characteristics were assessed by cases notes and the Mini-Mental State Examination, the Global Assessment Functional Scale and the Clinical Global Impression Scale. NPCs performed the best on the MacCAT-CR, and patients with SUD had the worst performance, particularly on the Understanding and Appreciation subscales. 32.7% SUD people lacked research-related decisional capacity. There were no statistically significant differences between the groups in terms of capacity to consent to research. The findings of our study provide evidence that a large proportion of individuals with SUD had decisional capacity for consent to research. It is therefore inappropriate to draw conclusions about capacity to make research decisions on the basis of a SUD diagnosis. In the absence of advanced cognitive impairment, acute withdrawal or intoxication, we should assume that addicted persons possess decision-making capacity. Thus, the view that people with SUD would ipso facto lose decision-making power for research consent is flawed and stigmatizing.

    Pain remains a critical medical challenge. Current treatments target nociception without addressing affective symptoms. Medically intractable pain is sometimes treated with cingulotomy or deep brain stimulation to increase tolerance of pain-related distress. Transcranial direct current stimulation (tDCS) may noninvasively modulate cortical areas related to sensation and pain representations. The present study aimed to test the hypothesis that cathodal ("inhibitory") stimulation targeting left dorsal anterior cingulate cortex (dACC) would increase tolerance to distress from acute painful stimuli vs anodal stimulation. Forty healthy volunteers received both anodal and cathodal stimulation. During stimulation, we measured pain distress tolerance with three tasks: pressure algometer, cold pressor, and breath holding. We measured pain intensity with a visual-analog scale before and after each task. Mixed ANOVA revealed that mean cold pressor tolerance tended to be higher with cathodal vs anodal stimulation (P = 0.055) for participants self-completing the task. Pressure algometer (P = 0.81) and breath holding tolerance (P = 0.19) did not significantly differ. The pressure algometer exhibited a statistically significant order effect irrespective of stimulation polarity (all P tDCS (P = 0.072). Although our primary results were nonsignificant, there is a preliminary suggestion that cathodal tDCS targeting left dACC may increase pain distress tolerance to cold pressor. Pressure algometer results are consistent with task-related sensitization. Future studies are needed to refine this novel approach for pain neuromodulation. Wiley Periodicals, Inc.

    The paper aims to review, design and implement a multidimensional performance measurement system for a public research hospital in order to address the complexity of its multifaceted stakeholder requirements and its double institutional aim of care and research. The methodology relies on a participative case study performed by external researchers in close collaboration with the staff of an Italian research hospital. The paper develops and applies a customized version of balanced scorecard based on a new set of performance measures. Our findings suggest that it can be considered an effective framework for measuring the research hospital performance, thanks to a combination of generalizable and context-specific factors. By showing how the balanced scorecard framework can be customized to research hospitals, the paper is especially of interest for complex healthcare organizations that are implementing management accounting practices. The paper contributes to the body of literature on the application of the balanced scorecard in healthcare through an examination of the challenges in designing and implementing this multidimensional performance tool. This is one of the first papers that show how the balanced scorecard model can be adapted to fit the specific requirements of public research hospitals.

    Shaping change such that it avoids losing potentially useful options for future development is a challenging task in the face of complex, coevolving socio-ecological systems. Sustainability appraisal methods, which open up dialogue and options before closing down and making suggestions, pay attention to the inclusion of various and conflicting points of view and address uncertainty, are increasingly used in the science, environment and energy policy domains. The quality of the process is seen as key to high quality appraisal outcomes. Dimensions of quality include learning opportunities which are seen as ways for addressing complexity and uncertainty. Participatory sustainability appraisal methods intend to support social learning among participants. Despite high expectations, social learning processes in sustainability appraisals are poorly conceptualized and empirically understudied. This paper (1) briefly reviews theories of social learning; (2) develops a conceptual framework for the analysis; and (3) presents an empirical application of the framework by use of data obtained from three energy and natural resource management case studies around Europe.

    Full Text Available Activity-travel behaviors of women and men are different because they have different social and household responsibilities. However, studies concerning gender differences are mainly limited in developed countries. This paper concentrates on gender role-based differences in activity-travel behavior in a typical developing country, namely, China. Using data from 3656 cases collected through surveys conducted in Shangyu, data processing, method choice, and descriptive analysis were conducted. Binary and ordered logistic regression models segmented by gender were developed to evaluate the mechanism through which individual sociodemographics, household characteristics, and activity participations affect the number of trip chain types and activities for women and men. The results show that women aged 30 to 50 perform less subsistence activities. However, the difference between the different age groups of men is not as significant. In addition, men with bicycles and electric bicycles have more subsistence and maintenance activities, whereas women do not have these attributes. Moreover, women with children under schooling age make more maintenance trip chains but less leisure trip chains and activities, whereas men are free from this influence. Furthermore, both women and men perform more subsistence activities if the duration increases, and men have less influences than women do.

    Research projects in translational science are increasingly complex and require interdisciplinary collaborations. In the context of training translational researchers, this suggests that multiple mentors may be needed in different content areas. This study explored mentoring structure as it relates to perceived mentoring effectiveness and other characteristics of master's-level trainees in clinical-translational research training programs. A cross-sectional online survey of recent graduates of clinical research master's program was conducted. Of 73 surveys distributed, 56.2% (n = 41) complete responses were analyzed. Trainees were overwhelmingly positive about participation in their master's programs and the impact it had on their professional development. Overall the majority (≥75%) of trainees perceived they had effective mentoring in terms of developing skills needed for conducting clinical-translational research. Fewer trainees perceived effective mentoring in career development and work-life balance. In all 15 areas of mentoring effectiveness assessed, higher rates of perceived mentor effectiveness was seen among trainees with ≥2 mentors compared to those with solo mentoring (SM). In addition, trainees with ≥2 mentors perceived having effective mentoring in more mentoring aspects (median: 14.0; IQR: 12.0-15.0) than trainees with SM (median: 10.5; IQR: 8.0-14.5). Results from this survey suggest having ≥2 mentors may be beneficial in fulfilling trainee expectations for mentoring in clinical-translational training. © 2015 Wiley Periodicals, Inc.

    Abstract Research projects in translational science are increasingly complex and require interdisciplinary collaborations. In the context of training translational researchers, this suggests that multiple mentors may be needed in different content areas. This study explored mentoring structure as it relates to perceived mentoring effectiveness and other characteristics of master's‐level trainees in clinical‐translational research training programs. A cross‐sectional online survey of recent graduates of clinical research master's program was conducted. Of 73 surveys distributed, 56.2% (n = 41) complete responses were analyzed. Trainees were overwhelmingly positive about participation in their master's programs and the impact it had on their professional development. Overall the majority (≥75%) of trainees perceived they had effective mentoring in terms of developing skills needed for conducting clinical‐translational research.

    Full Text Available Background. It is unclear if CD4 cell counts at HIV diagnosis have improved over a 10-year period of expanded HIV testing in the USA. Methods. We studied HOPS participants diagnosed with HIV infection ≤6 months prior to entry into care during 2000–2009. We assessed the correlates of CD4 count <200 cells/mm3 at HIV diagnosis (late HIV diagnosis by logistic regression. Results. Of 1,203 eligible patients, 936 (78% had a CD4 count within 3 months after HIV diagnosis. Median CD4 count at HIV diagnosis was 299 cells/mm3 and did not significantly improve over time (P=0.13. Comparing periods 2000-2001 versus 2008-2009, respectively, 39% and 35% of patients had a late HIV diagnosis (P=0.34. Independent correlates of late HIV diagnosis were having an HIV risk other than being MSM, age ≥35 years at diagnosis, and being of nonwhite race/ethnicity. Conclusions. There is need for routine universal HIV testing to reduce the frequency of late HIV diagnosis and increase opportunity for patient- and potentially population-level benefits associated with early antiretroviral treatment.
