    Full Text Available This study is an attempt to investigate the motivation behind the decision to participate in the credit market of SMEs from perspectives of behavioral finance and social capital theories. In addi- tion, the study also examines the effect of behavioral finance and social capital factors on the credit source selection among SMEs. This study’s design strategy involves conducting questionnaire sur- veys to SMEs owners and statistical techniques to analyze the determinants of credit participation and credit source selection of borrowers. The findings showed that personal traits of SMEs owners/ managers in terms of behavioral finance factors such as debt and risk attitudes, present biased and overconfidence and firms networking also have impacts on the firms’ credit participation and credit source selection. The research is one of the few studies that consider the influence of behavioral finance factors on firms financing decision. Furthermore, our result also contributes to explain the common use of informal credit market in developing countries.

    2014-07-01

    Studies have shown participation in sport is lower among girls than boys, decreases as students matriculate through high school, is lowest among Black and Hispanic girls and has a positive relationship with SES. With sport recognized as a contributor to physical activity and health in adolescents, consideration of diminishing rates of participation appears warranted. The purpose of this study was to identify patterns related to differences in self-reported sport participation between genders, ethnic groups, grades and SES. This study was a cross-sectional, secondary analysis of data collected for a sport interest survey. All students in grades 8-11 attending middle and high schools were provided an opportunity to participate in the survey. Data from 49,832 students were analyzed. Among the participants, Black girls participated more and White girls participated less than expected. Black boys participated more while White and Asian boys participated less than expected. Reported sport participation was high compared with national data when analyzed by gender and ethnic group. Sport participation was higher in low SES schools compared with high SES schools. The importance of sport as a source of physical activity in underserved groups is significant.

  8. Auralization of airborne sound insulation including the influence of source room

    DEFF Research Database (Denmark)

    Rindel, Jens Holger

    2006-01-01

    The paper describes a simple and acoustically accurate method for the auralization of airborne sound insulation between two rooms by means of a room acoustic simulation software (ODEON). The method makes use of a frequency independent transparency of the transmitting surface combined...... with a frequency dependent power setting of the source in the source room. The acoustic properties in terms of volume and reverberation time as well as the area of the transmitting surface are all included in the simulation. The user only has to select the position of the source in the source room and the receiver...... of the transmitting surface is used for the simulation of sound transmission. Also the reduced clarity of the auralization due to the reverberance of the source room is inherent in the method. Currently the method is restricted to transmission loss data in octave bands....

    Parwani, Ajit K.; Talukdar, Prabal; Subbarao, P.M.V.

    2013-01-01

    An inverse heat transfer problem is discussed to estimate simultaneously the unknown position and timewise varying strength of a heat source by utilizing differential evolution approach. A two dimensional enclosure with isothermal and black boundaries containing non-scattering, absorbing and emitting gray medium is considered. Both radiation and conduction heat transfer are included. No prior information is used for the functional form of timewise varying strength of heat source. The finite volume method is used to solve the radiative transfer equation and the energy equation. In this work, instead of measured data, some temperature data required in the solution of the inverse problem are taken from the solution of the direct problem. The effect of measurement errors on the accuracy of estimation is examined by introducing errors in the temperature data of the direct problem. The prediction of source strength and its position by the differential evolution (DE) algorithm is found to be quite reasonable. -- Highlights: •Simultaneous estimation of strength and position of a heat source. •A conducting and radiatively participating medium is considered. •Implementation of differential evolution algorithm for such kind of problems. •Profiles with discontinuities can be estimated accurately. •No limitation in the determination of source strength at the final time

  17. Do the enigmatic ``Infrared-Faint Radio Sources'' include pulsars?

    Science.gov (United States)

    Hobbs, George; Middelberg, Enno; Norris, Ray; Keith, Michael; Mao, Minnie; Champion, David

    2009-04-01

    The Australia Telescope Large Area Survey (ATLAS) team have surveyed seven square degrees of sky at 1.4GHz. During processing some unexpected infrared-faint radio sources (IFRS sources) were discovered. The nature of these sources is not understood, but it is possible that some of these sources may be pulsars within our own galaxy. We propose to observe the IFRS sources with steep spectral indices using standard search techniques to determine whether or not they are pulsars. A pulsar detection would 1) remove a subset of the IFRS sources from the ATLAS sample so they would not need to be observed with large optical/IR telescopes to find their hosts and 2) be intrinsically interesting as the pulsar would be a millisecond pulsar and/or have an extreme spatial velocity.

  18. Pseudodynamic Source Characterization for Strike-Slip Faulting Including Stress Heterogeneity and Super-Shear Ruptures

    KAUST Repository

    Mena, B.

    2012-08-08

    Reliable ground‐motion prediction for future earthquakes depends on the ability to simulate realistic earthquake source models. Though dynamic rupture calculations have recently become more popular, they are still computationally demanding. An alternative is to invoke the framework of pseudodynamic (PD) source characterizations that use simple relationships between kinematic and dynamic source parameters to build physically self‐consistent kinematic models. Based on the PD approach of Guatteri et al. (2004), we propose new relationships for PD models for moderate‐to‐large strike‐slip earthquakes that include local supershear rupture speed due to stress heterogeneities. We conduct dynamic rupture simulations using stochastic initial stress distributions to generate a suite of source models in the magnitude Mw 6–8. This set of models shows that local supershear rupture speed prevails for all earthquake sizes, and that the local rise‐time distribution is not controlled by the overall fault geometry, but rather by local stress changes on the faults. Based on these findings, we derive a new set of relations for the proposed PD source characterization that accounts for earthquake size, buried and surface ruptures, and includes local rise‐time variations and supershear rupture speed. By applying the proposed PD source characterization to several well‐recorded past earthquakes, we verify that significant improvements in fitting synthetic ground motion to observed ones is achieved when comparing our new approach with the model of Guatteri et al. (2004). The proposed PD methodology can be implemented into ground‐motion simulation tools for more physically reliable prediction of shaking in future earthquakes.

  19. A practical algorithm for distribution state estimation including renewable energy sources

    Renewable energy is energy that is in continuous supply over time. These kinds of energy sources are divided into five principal renewable sources of energy: the sun, the wind, flowing water, biomass and heat from within the earth. According to some studies carried out by the research institutes, about 25% of the new generation will be generated by Renewable Energy Sources (RESs) in the near future. Therefore, it is necessary to study the impact of RESs on the power systems, especially on the distribution networks. This paper presents a practical Distribution State Estimation (DSE) including RESs and some practical consideration. The proposed algorithm is based on the combination of Nelder-Mead simplex search and Particle Swarm Optimization (PSO) algorithms, called PSO-NM. The proposed algorithm can estimate load and RES output values by Weighted Least-Square (WLS) approach. Some practical considerations are var compensators, Voltage Regulators (VRs), Under Load Tap Changer (ULTC) transformer modeling, which usually have nonlinear and discrete characteristics, and unbalanced three-phase power flow equations. The comparison results with other evolutionary optimization algorithms such as original PSO, Honey Bee Mating Optimization (HBMO), Neural Networks (NNs), Ant Colony Optimization (ACO), and Genetic Algorithm (GA) for a test system demonstrate that PSO-NM is extremely effective and efficient for the DSE problems.

    Tremendous increases in biodegradable (food waste) generation significantly impact the local authorities, who are responsible to manage, treat and dispose of this waste. The process of separation of food waste at its generation source is identified as effective means in reducing the amount food waste sent to landfill and can be reused as feedstock to downstream treatment processes namely composting or anaerobic digestion. However, these efforts will only succeed with positive attitudes and highly participations rate by the public towards the scheme. Thus, the social survey (using questionnaires) to analyse public's view and influencing factors towards participation in source separation of food waste in households based on the theory of planned behaviour technique (TPB) was performed in June and July 2011 among selected staff in Universiti Putra Malaysia, Serdang, Selangor. The survey demonstrates that the public has positive intention in participating provided the opportunities, facilities and knowledge on waste separation at source are adequately prepared by the respective local authorities. Furthermore, good moral values and situational factors such as storage convenience and collection times are also encouraged public's involvement and consequently, the participations rate. The findings from this study may provide useful indicator to the waste management authorities in Malaysia in identifying mechanisms for future development and implementation of food waste source separation activities in household programmes and communication campaign which advocate the use of these programmes.

    2016-03-01

    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.

    Full Text Available In The Role of Participation Architecture in Growing Sponsored Open Source Communities, Joel West and Siobhan O'Mahony argue that "to some extent, firms and technical communities have always collaborated to create standards, shared infrastructure, and innovation outcomes that are bigger than any one firm can achieve." and that "there is increasing evidence that path breaking innovations cannot occur without a community to interpret, support, extend and diffuse them". When considered in this light, it should not be surprising that more enterprises, both large and small, are increasing their participation in open source communities to drive innovation. The theme for this month's issue of the OSBR is enterprise participation and the authors provide practical advice for effective enterprise/community collaboration. Their experiences provide perspectives on: i the Eclipse Foundation, which maintains an ecosystem of over 150 enterprises that participate in Eclipse open source projects; ii an independent software vendor that sells closed source solutions constructed on top of an open source platform to large enterprise customers; iii the impact of major players collaborating on a common open source platform for the mobile industry; iv the role users can play in the very large (over 14 million GNOME community; and v the lessons a scientist from the National Research Council of Canada learned when he released software and started a small open source community.

    2017-12-01

    Widening participation into higher education is espoused within educational policy in the UK, and internationally, as a mechanism to promote equality and social mobility. As nurse education is located within higher education it has a responsibility to promote widening participation within pre-registration educational programmes. It could also be argued that the profession has a responsibility to promote equality to ensure its' workforce is as diverse as possible in order to best address the health needs of diverse populations. To undertake an integrative review on published papers exploring Widening Participation in undergraduate, pre-registration nurse education in the UK. A six step integrative review methodology was utilised, reviewing papers published in English from 2013-2016. Search of CINAHL, Education Source, MEDLINE, PsychINFO, SocINDEX, Science Direct, Business Source Complete, ERIC, British Library ETOS, Teacher Reference Centre, Informit Health Collection and Informit Humanities and Social Science Collection which highlighted 449 citations; from these 14 papers met the review inclusion criteria. Both empirical studies and editorials focusing upon widening participation in pre-registration nurse education in the UK (2013-2016) were included. Papers excluded were non UK papers or papers not focussed upon widening participation in pre-registration nursing education. Research papers included in the review were assessed for quality using appropriate critical appraisal tools. 14 papers were included in the review; these were analysed thematically identifying four themes; knowledge and identification of WP, pedagogy and WP, attrition and retention and career prospects. Whilst widening participation is a key issue for both nurse education and the wider profession there is a lack of conceptualisation and focus regarding mechanisms to both encourage and support a wider diversity of entrant. Whilst there are some studies, these focus on particular individual

  7. The coordination of problem solving strategies: when low competence sources exert more influence on task processing than high competence sources.

    2009-03-01

    Previous research has shown that low competence sources, compared to highly competent sources, can exert influence in aptitudes tasks in as much as they induce people to focus on the task and to solve it more deeply. Two experiments aimed at testing the coordination between self and source's problem solving strategies as a main explanation of such a difference in influence. The influence of a low versus high competence source has been examined in an anagram task that allows for distinguishing between three response strategies, including one that corresponds to the coordination between the source's strategy and participants' own strategy. In Study 1 the strategy suggested by the source was either relevant and useful or irrelevant and useless for solving the task. Results indicated that participants used the coordination strategy in a larger extend when they had been confronted to a low competence rather than a highly competent source but only when the source displayed a strategy that was useful to solve the task. In Study 2 the source's strategy was always relevant and useful, but a decentring procedure was introduced for half of the participants. This procedure induced participants to consider other points of view than their own. Results replicated the difference observed in Study 1 when no decentring was introduced. The difference however disappeared when decentring was induced, because of an increase of the high competence source's influence. These results highlight coordination of strategies as one mechanism underlying influence from low competence sources.

    Research on light-water reactor severe accidents (SA) is still required in a limited number of areas in order to confirm accident-management plans. Thus, 49 European organizations have linked their SA research in a durable way through SARNET (Severe Accident Research and management NETwork), part of the European 6th Framework Programme. One goal of SARNET is to consolidate the integral code ASTEC (Accident Source Term Evaluation Code, developed by IRSN and GRS) as the European reference tool for safety studies; SARNET efforts include extending the application scope to reactor types other than PWR (including VVER) such as BWR and CANDU. ASTEC is used in IRSN's Probabilistic Safety Analysis level 2 of 900 MWe French PWRs. An earlier version of ASTEC's SOPHAEROS module, including improvements by AECL, is being validated as the Canadian Industry Standard Toolset code for FP-transport analysis in the CANDU Heat Transport System. Work with ASTEC has also been performed by Bhabha Atomic Research Centre, Mumbai, on IPHWR containment thermal hydraulics. (author)

  12. The use of source memory to identify one's own episodic confusion errors.

    Smith, S M; Tindell, D R; Pierce, B H; Gilliland, T R; Gerkens, D R

    2001-03-01

    In 4 category cued recall experiments, participants falsely recalled nonlist common members, a semantic confusion error. Errors were more likely if critical nonlist words were presented on an incidental task, causing source memory failures called episodic confusion errors. Participants could better identify the source of falsely recalled words if they had deeply processed the words on the incidental task. For deep but not shallow processing, participants could reliably include or exclude incidentally shown category members in recall. The illusion that critical items actually appeared on categorized lists was diminished but not eradicated when participants identified episodic confusion errors post hoc among their own recalled responses; participants often believed that critical items had been on both the incidental task and the study list. Improved source monitoring can potentially mitigate episodic (but not semantic) confusion errors.

    To explore how the meaning of exercise and other factors interact and influence the exercise behaviour of individuals with Parkinson's disease (PD) enrolled in a 6-month minimally supervised exercise program to prevent falls, regardless of whether they completed the prescribed exercise or not. This qualitative study utilised in-depth semi-structured interviews analysed using grounded theory methodology. Four main themes were constructed from the data: adapting to change and loss, the influence of others, making sense of the exercise experience and hope for a more active future. Participation in the PD-specific physiotherapy program involving group exercise provided an opportunity for participants to reframe their identity of their "active" self. Three new influences on exercise participation were identified and explored: non-motor impairments of apathy and fatigue, the belief in a finite energy quota, and the importance of feedback. A model was developed incorporating the themes and influences to explain decision-making for exercise participation in this group. Complex and interacting issues, including non-motor impairments, need to be considered in order to enhance the development and ongoing implementation of effective exercise programmes for people with PD. Exercise participation can assist individuals to reframe their identity as they are faced with losses associated with Parkinson's disease and ageing. Non-motor impairments of apathy and fatigue may influence exercise participation in people with Parkinson's disease. Particular attention needs to be paid to the provision of feedback in exercise programs for people with Parkinson's disease as it important for their decision-making about continuing exercise.

    Ground source heat is a collective name for tapping, recharging and storing thermal energy at moderate temperature in the bedrock, ground water and soil (renewable energy). By means of heat pumps, ground source heating systems can be used as highly energy efficient and environmentally-friendly heating and cooling in all kinds of buildings. IEA's heat pump programme (IEA HPP) has in the period March 2004 to June 2006 carried out an Annex on heating pump systems based on ground source heat: 'Annex 29 - Ground-source heat pumps overcoming market and technical barriers'. The project has i.a. covered the development of more cost- and energy efficient solutions, identification and analysis of market obstacles, technology transfer and the task of making visible the energy economising potential and environmental gains that this type of systems represent. The six participating countries have been Canada, Japan, Norway, Sweden, USA and Austria (operating agent). Norway's participation in IEA Annex 29 has been financed by ENOVA SF, while SINTEF Energy research AS has been in charge of planning and executing the Norwegian project activities. This report provides a general presentation of ground source heat pump systems, and gives a summary of the most important Norwegian activities in IEA Annex 29, which includes: The development of a Norwegian internet home page (http://www.energy.sintef.no/prosjekt/annex29), preparation of Norwegian status report, initiation, coordination and carrying out of Norwegian research projects and reports, communication of results (technology transfer) in Norway, networking activities towards important market actors in Norway, participation and delivering discourse at international seminars (workshops), and participation at international working sessions (ml)

    In early 1995, the receipt of four sealed californium-252 sources from Oak Ridge National Lab was successfully accomplished by a team comprised of Radiological Engineering, Radiological Operations and Health Physics Instrumentation personnel. A procedure was developed and walked-down by the participants during a Dry Run Evolution. Several special tools were developed during the pre-planning phases of the project which reduced individual and job dose to minimal levels. These included a mobile lifting device for attachment of a transfer ball valve assembly to the undercarriage of the Cannonball Carrier, a transfer tube elbow to ensure proper angle of the source transfer tube, and several tools used during emergency response for remote retrieval and handling of an unshielded source. Lessons were learned in the areas of contamination control, emergency preparedness, and benefits of thorough pre-planning, effectiveness of locally creating and designing special tools to reduce worker dose, and methods of successfully accomplishing source receipt evolutions during extreme or inclement weather

    Water, food and energy is three sacred treasures that are necessary for human beings. However, recent factors such as population growth and rapid increase in energy consumption have generated conflicting cases between water and energy. For example, there exist conflicts caused by enhanced energy use, such as between hydropower generation and riverine ecosystems and service water, between shale gas and ground water, between geothermal and hot spring water. This study aims to provide quantitative guidelines necessary for capacity building among various stakeholders to minimize water-energy conflicts in enhancing energy use. Among various kinds of renewable energy sources, we target baseload sources, especially focusing on renewable energy of which installation is required socially not only to reduce CO2 and other greenhouse gas emissions but to stimulate local economy. Such renewable energy sources include micro/mini hydropower and geothermal. Three municipalities in Japan, Beppu City, Obama City and Otsuchi Town are selected as primary sites of this study. Based on the calculated potential supply and demand of micro/mini hydropower generation in Beppu City, for example, we estimate the electricity of tens through hundreds of households is covered by installing new micro/mini hydropower generation plants along each river. However, the result is based on the existing infrastructures such as roads and electric lines. This means that more potentials are expected if the local society chooses options that enhance the infrastructures to increase micro/mini hydropower generation plants. In addition, further capacity building in the local society is necessary. In Japan, for example, regulations by the river law and irrigation right restrict new entry by actors to the river. Possible influences to riverine ecosystems in installing new micro/mini hydropower generation plants should also be well taken into account. Deregulation of the existing laws relevant to rivers and

    Social media users post messages about health goals and behaviors to online social networks. Compared with more traditional sources of health communication such as physicians or health journalists, peer sources are likely to be perceived as more socially close or similar, which influences how messages are processed. This experimental study uses construal level theory of psychological distance to predict how mediated health messages from peers influence health-related cognition and behavioral intention. Participants were exposed to source cues that identified peer sources as being either highly attitudinally and demographically similar to or different from participants. As predicted by construal level theory, participants who perceived sources of social media health messages as highly similar listed a greater proportion of beliefs about the feasibility of health behaviors and a greater proportion of negative beliefs, while participants who perceived sources as more dissimilar listed a greater proportion of positive beliefs about the health behaviors. Results of the study could be useful in determining how health messages from peers could encourage individuals to set realistic health goals.

    The first meeting devoted to cold neutron sources was held at the Los Alamos National Laboratory on March 5--8, 1990. Cosponsored by Los Alamos and Oak Ridge National Laboratories, the meeting was organized as an International Workshop on Cold Neutron Sources and brought together experts in the field of cold-neutron-source design for reactors and spallation sources. Eighty-four people from seven countries attended. Because the meeting was the first of its kind in over forty years, much time was spent acquainting participants with past and planned activities at reactor and spallation facilities worldwide. As a result, the meeting had more of a conference flavor than one of a workshop. The general topics covered at the workshop included: Criteria for cold source design; neutronic predictions and performance; energy deposition and removal; engineering design, fabrication, and operation; material properties; radiation damage; instrumentation; safety; existing cold sources; and future cold sources.

    This study aims to (a) examine the roles of knowledge, distrust in medical professionals, information sources, and 2 dimensions of religiosity (i.e., religious activity and religious belief) in influencing willingness to participate (WTP) in cancer clinical trials and to (b) compare the results for Caucasians and African Americans in order to inform future recruitment. An online survey was fielded via a Knowledge Networks panel with a nationally representative sample including 478 Caucasians and 173 African Americans. The results showed that distrust in medical professionals was a strong barrier to WTP for both ethnic groups, whereas factual knowledge about trial procedures was not associated with WTP for either ethnic group. Seeking trial information from doctors was positively associated with WTP for Caucasians; seeking trial information from hospitals was positively associated with WTP for African Americans. More interestingly, levels of religious activity negatively predicted WTP for Caucasians but positively predicted WTP for African Americans. Self-reported religious belief was not associated with WTP for either ethnic group. In sum, although distrust is a common barrier to WTP, the influence of preferred information sources and religious activity on WTP varies as a function of ethnicity.

    Williams, Randi

    This study was designed to explore elementary STEM professional development viewed from the presenters' and participants' perspectives. Numerous committees and educational organizations recommend investing in STEM professional development at the local, state, and national level. This investment must begin with research that inquires how STEM professional development is structured and what is needed for teacher and student success. Since there is a recent STEM education push in schools, elementary teachers need effective professional development in order to gain the necessary content, skills, confidence, and pedagogy required for those changing demands. This qualitative study embraced. Yin's case study methodology by observing short-duration STEM professional development for elementary teachers within a large metropolitan school system and an educational professional development agency. The study discussed the analysis and findings in the context of Bandura's sources of efficacy and Desimone's critical features of professional development. Data were gathered form professional development observations, presenter interviews, and participant interviews. The research questions for this study included: (a) based on Desimone's (2009) framework for professional development, what does content focused, active learning, coherence, duration, and collective participation look like in initial STEM professional development for elementary teachers? (b) are Bandura's (1997) four sources of self- efficacy: mastery experiences, vicarious experiences, social persuasion, and affective states evidenced within the short duration professional development? and (c) how do these two frameworks align between presenter and participant thoughts and actions? This study uncovered additional sources of efficacy are present in short-duration STEM professional development. These found sources include coherence, content, and active learning delivered in a definitive order. The findings of this study

    Driven by the recent trends in the GIS domain including Volunteered Geographic Information, geo-crowdsourcing and citizen science, and fostered by the constant technological advances, collection and dissemination of geospatial information by ordinary people has become commonplace. However, applications involving user-generated geospatial content show dramatically diversified patterns in terms of incentive, type and level of participation, purpose of the activity, data/metadata provided and data quality. This study contributes to this heterogeneous context by investigating public participation in GIS within the field of mobile-based applications. Results not only show examples of how to technically build GIS applications enabling user collection and interaction with geospatial data, but they also draw conclusions about the methods and needs of public participation. We describe three projects with different scales and purposes in the context of urban monitoring and planning, and tourism valorisation. In each case, an open source architecture is used, allowing users to exploit their mobile devices to collect georeferenced information. This data is then made publicly available on specific Web viewers. Analysis of user involvement in these projects provides insights related to participation patterns which suggests some generalized conclusions.

    Multi-source feedback (MSF) enables performance data to be provided to doctors from patients, co-workers and medical colleagues. This study examined the evidence for the validity of MSF instruments for general practice, investigated changes in performance for doctors who participated twice, 5 years apart, and determined the association between change in performance and initial assessment and socio-demographic characteristics. Data for 250 doctors included three datasets per doctor from, respectively, 25 patients, eight co-workers and eight medical colleagues, collected on two occasions. There was high internal consistency (alpha > 0.90) and adequate generalisability (Ep(2) > 0.70). D study results indicate adequate generalisability coefficients for groups of eight assessors (medical colleagues, co-workers) and 25 patient surveys. Confirmatory factor analyses provided evidence for the validity of factors that were theoretically expected, meaningful and cohesive. Comparative fit indices were 0.91 for medical colleague data, 0.87 for co-worker data and 0.81 for patient data. Paired t-test analysis showed significant change between the two assessments from medical colleagues and co-workers, but not between the two patient surveys. Multiple linear regressions explained 2.1% of the variance at time 2 for medical colleagues, 21.4% of the variance for co-workers and 16.35% of the variance for patient assessments, with professionalism a key variable in all regressions. There is evidence for the construct validity of the instruments and for their stability over time. Upward changes in performance will occur, although their effect size is likely to be small to moderate.

    Interest in Internet-based epidemiologic research is growing given the logistic and cost advantages. Cohort recruitment to maximally diversify the sociodemographic profiles of participants, however, remains a contentious issue. The aim of the study was to characterize the sociodemographic profiles according to the recruitment mode of adult volunteers enrolled in a Web-based cohort. The French NutriNet-Santé Web-based cohort was launched in 2009. Recruitment is ongoing and largely relies on recurrent multimedia campaigns. One month after enrollment, participants are asked how they learned about the study (eg, general newscast or a health program on television, radio newscast, newspaper articles, Internet, personal advice, leaflet/flyers) The sociodemographic profiles of participants recruited through operative communication channels (radio, print media, Internet, advice) were compared with the profiles of those informed through television by using polytomous logistic regression. Among the 88,238 participants enrolled through the end of 2011, 30,401 (34.45%), 16,751 (18.98%), and 14,309 (16.22%) learned about the study from television, Internet, and radio newscasts, respectively. Sociodemographic profiles were various, with 14,541 (16.5%) aged ≥60 years, 20,166 (22.9%) aged income income €3700/month. Compared to employed individuals, unemployed and retired participants were less likely to be informed about the study through other sources than through television (adjusted ORs 0.56-0.83, Pbased studies regarding the development of promising targeted or general population recruitment strategies.

  7. Medial temporal lobe reinstatement of content-specific details predicts source memory

    2016-01-01

    Leading theories propose that when remembering past events, medial temporal lobe (MTL) structures reinstate the neural patterns that were active when those events were initially encoded. Accurate reinstatement is hypothesized to support detailed recollection of memories, including their source. While several studies have linked cortical reinstatement to successful retrieval, indexing reinstatement within the MTL network and its relationship to memory performance has proved challenging. Here, we addressed this gap in knowledge by having participants perform an incidental encoding task, during which they visualized people, places, and objects in response to adjective cues. During a surprise memory test, participants saw studied and novel adjectives and indicated the imagery task they performed for each adjective. A multivariate pattern classifier was trained to discriminate the imagery tasks based on functional magnetic resonance imaging (fMRI) responses from hippocampus and MTL cortex at encoding. The classifier was then tested on MTL patterns during the source memory task. We found that MTL encoding patterns were reinstated during successful source retrieval. Moreover, when participants made source misattributions, errors were predicted by reinstatement of incorrect source content in MTL cortex. We further observed a gradient of content-specific reinstatement along the anterior-posterior axis of hippocampus and MTL cortex. Within anterior hippocampus, we found that reinstatement of person content was related to source memory accuracy, whereas reinstatement of place information across the entire hippocampal axis predicted correct source judgments. Content-specific reinstatement was also graded across MTL cortex, with PRc patterns evincing reactivation of people and more posterior regions, including PHc, showing evidence for reinstatement of places and objects. Collectively, these findings provide key evidence that source recollection relies on reinstatement of past

    Many chronic diseases are responsive to interventions focused on diet and physical activity. The Complete Health Improvement Program (CHIP) is an intensive, community-based lifestyle intervention that effectively treats many chronic diseases and their risk factors. This is a pilot study examining the effect of payer source for CHIP tuition on participants' outcomes. Seventy-nine self-selected participants (73.4% female) attended 1 of 3 CHIP classes (classes 7-9) offered January through May 2013 in Athens, Ohio. Participants were categorized into 3 groups based on the source(s) of their tuition payment: self-pay, employer-pay, or scholarship. Chronic disease risk factors for each individual were assessed at the beginning and conclusion of the program. Outcome variables included percent reduction between pre- and post CHIP measures in body mass index, systolic and diastolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, and fasting blood glucose. Results were compared between type of payer source (out of pocket vs employer and/or scholarship) and between each individual CHIP class attended. There was no statistical difference in outcomes based on payer source. Those who received funding through their employer or a scholarship experienced similar effects from a lifestyle intervention program as those who paid out of pocket. This study demonstrates that the benefit of CHIP for reducing chronic disease risk factors exists independent of payment source, and thus suggests its benefit may cross socioeconomic lines.

    Evaluating participation programmes, projects and activities aids understanding of effective mechanisms and enables the identification of improvements to current strategies. Characteristics of participation processes, such whether the process is cost effective, adequately facilitated, accessible, includes a representative section of society or interest groups and allocates power equivalently between participants, are commonly described and evaluated in the literature. A key question concerns whether effective processes lead to desirable outcomes. Two types of outcomes can be identified from participation programmes - tangible and non-tangible. Tangible outcomes include resource management changes or resource quality changes. Non tangible outcomes include developing and strengthening communication and action networks, building trust between individuals and/or organisations, developing innovative solutions, or developing shared knowledge and understandings of issues. To better understand how participation impacts upon resource management it is necessary to identify i) how non-tangible outcomes lead to resource management outcomes and ii) which characteristics of the participation process are connected to achieving non-tangible outcomes. This has been attempted with a literature based meta-analysis. Literature has been analysed to identify outcomes from participations programmes, and the process characteristics present that are associated with promoting or inhibiting their achievement. Preliminary analysis shows that process characteristics such as representation, facilitation and accessibility are important for achieving non-tangible outcomes. The relationship between non-tangible outcomes and resource management outcomes is less clear in the literature. This may be due to the different timescales over which the different types of outcomes emerge (resource management outcomes emerge over longer time periods) and the different contexts or settings in which

    Destination memory refers to the recall of the destination of previously relayed information, and source memory refers to the recollection of the origin of received information. We compared both memory systems in Huntington's disease (HD) participants. For this, HD participants and healthy adults had to put 12 items in a black or a white box (destination task), and to extract another 12 items from a blue or a red box (source task). Afterwards, they had to decide in which box each item had previously been deposited (destination memory), and from which box each item had previously been extracted (source memory). HD participants showed poorer source as well as destination recall performance than healthy adults in the proposed tasks. Correlation analysis showed that destination recall was significantly correlated with episodic recall in HD participants. Destination memory impairment in HD participants seems to be considerably influenced by their episodic memory performance. © 2014 The British Psychological Society.

    Craniopharyngioma is a rare, benign central nervous system tumor, which may be a source of multiple complications, from endocrinology to vision, neurology and neurocognitive functions. This morbidity can lead to reduced participation in life activities, as described in the International Classification of Functioning, Disability, and Health. The primary objective of this study was to measure participation in life activities in a population of children and young adults affected by childhood craniopharyngioma, using the LIFE-H questionnaire (Assessment of Life Habits), validated as a social participation measurement tool in various pediatric disabilities. We also describe complications in our population and examined the potential links between tumor characteristics, complications, and participation in life activities. This was a descriptive study, including all patients having presented childhood craniopharyngioma (before 18 years of age), followed in the Lyon region between 2007 and 2013. The main criterion was the LIFE-H results, completed by the patient or the carer. Of 21 patients included in the study, 14 completed the questionnaire, a mean 6.7 years after the diagnosis (SD: 3.9 years). The mean total LIFE-H score was 8.4 (SD: 1.03) for a normal score estimated at 10 in the general population. The lowest scores affected the nutrition, community life, and recreation dimensions. No patient had a normal score on all dimensions; 57% of the patients had more than three dimensions affected. The variability of the results between patients was lower for some dimensions with high means (fitness, personal care, communication, housing, mobility, responsibilities, and education) than in others (nutrition, interpersonal relationships, community life, employment, and recreation) with rather low means. All patients had an endocrinological deficit, 19% hypothalamic syndrome, 52% an impaired fulfillment feeling, 76% visual impairment, 14% neurologic impairment, and 91

    2004-03-15

    We have developed a toolbox and graphic user interface, EEGLAB, running under the crossplatform MATLAB environment (The Mathworks, Inc.) for processing collections of single-trial and/or averaged EEG data of any number of channels. Available functions include EEG data, channel and event information importing, data visualization (scrolling, scalp map and dipole model plotting, plus multi-trial ERP-image plots), preprocessing (including artifact rejection, filtering, epoch selection, and averaging), independent component analysis (ICA) and time/frequency decompositions including channel and component cross-coherence supported by bootstrap statistical methods based on data resampling. EEGLAB functions are organized into three layers. Top-layer functions allow users to interact with the data through the graphic interface without needing to use MATLAB syntax. Menu options allow users to tune the behavior of EEGLAB to available memory. Middle-layer functions allow users to customize data processing using command history and interactive 'pop' functions. Experienced MATLAB users can use EEGLAB data structures and stand-alone signal processing functions to write custom and/or batch analysis scripts. Extensive function help and tutorial information are included. A 'plug-in' facility allows easy incorporation of new EEG modules into the main menu. EEGLAB is freely available (http://www.sccn.ucsd.edu/eeglab/) under the GNU public license for noncommercial use and open source development, together with sample data, user tutorial and extensive documentation.

    Preliminary evidence suggests beneficial effects of transcranial magnetic stimulation (TMS) on anxiety. The objective of this study was to investigate the effects of intermittent theta burst stimulation (iTBS) as a form of TMS on acute anxiety provoked by a virtual reality (VR) scenario. Participants with spider phobia (n=41) and healthy controls (n=42) were exposed to a spider scenario in VR after one session of iTBS over the prefrontal cortex or sham treatment. Participants with spider phobia reacted with more anxiety compared to healthy controls. Their heart rate and skin conductance increased compared to baseline. Contrary to expectations, iTBS did not influence these reactions, but modulated heart rate variability (HRV). Sympathetic influence on HRV showed an increase in the active iTBS group only. This study does not support the idea of beneficial effects of a single session of iTBS on anxiety, although other protocols or repeated sessions might be effective. Copyright © 2015 Elsevier B.V.

    The traditional interpretation of symptom over-reporting is that it indicates malingering. We explored a different perspective, namely that over-reporting of eccentric symptoms is related to deficits in articulating internal experiences (i.e., alexithymia). Given that alexithymia has been linked to sleep problems and that fatigue may fuel inattentive responding to symptom lists, we administered measures of alexithymia (TAS-20) and symptom over-reporting (SIMS), but also sleep quality (SLEEP-50) to forensic psychiatric outpatients (n = 40) and non-forensic participants (n = 40). Forensic patients scored significantly higher on all three indices than non-forensic participants. In the total sample as well as in subsamples, over-reporting correlated positively and significantly with alexithymia, with rs being in the 0.50-0.65 range. Sleep problems were also related to over-reporting, but in the full sample and in the forensic subsample, alexithymia predicted variance in over-reporting over and above sleep problems. Although our study is cross-sectional in nature, its results indicate that alexithymia as a potential source of over-reporting merits systematic research. © 2018 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    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 ADAPT (ADapting pharmacists' skills and Approaches to maximize Patients' drug Therapy effectiveness) e-learning programme requires weekly participation in module activities and facilitated discussion to support skill uptake. In this study, we sought to describe the extent and pattern of, satisfaction with and factors affecting participation in the initial programme offering and reasons for withdrawal. Mixed methods - convergent parallel approach. Participation was examined in qualitative data from discussion boards, assignments and action plans. Learner estimations of time commitment and action plan submission rates were calculated. Surveys (Likert scale and open-ended questions) included mid-point and final, exit and participation surveys. Eleven of 86 learners withdrew, most due to time constraints (eight completed an exit survey; seven said they would take ADAPT again). Thirty-five of 75 remaining learners completed a participation survey. Although 50-60% of the remaining 75 learners actively continued participating, only 15/35 respondents felt satisfied with their own participation. Learners spent 3-5 h/week (average) on module activities. Factors challenging participation included difficulty with technology, managing time and group work. Factors facilitating participation included willingness to learn (content of high interest) and supportive work environment. Being informed of programme time scheduling in advance was identified as a way to enhance participation. This study determined extent of learner participation in an online pharmacist continuing education programme and identified factors influencing participation. Interactions between learners and the online interface, content and with other learners are important considerations for designing online education programmes. Recommendations for programme changes were incorporated following this evaluation to facilitate participation. © 2015 Royal Pharmaceutical Society.

    The purpose of this study was to evaluate surgical preparation methods of medical students, residents, and faculty with special attention to video usage. Following Institutional Review Board approval, anonymous surveys were distributed to participants. Information collected included demographics and surgical preparation methods, focusing on video usage. Participants were questioned regarding frequency and helpfulness of videos, video sources used, and preferred methods between videos, reading, and peer consultation. Statistical analysis was performed using SAS. Surveys were distributed to participants in the Department of Surgery at the University of Iowa Hospitals and Clinics, a tertiary care center in Iowa City, Iowa. Survey participants included fourth-year medical students pursuing general surgery, general surgery residents, and faculty surgeons in the Department of Surgery. A total of 86 surveys were distributed, and 78 surveys were completed. This included 42 learners (33 residents, 9 fourth-year medical students) and 36 faculty. The overall response rate was 91%; 90% of respondents reported using videos for surgical preparation (learners = 95%, faculty = 83%, p = NS). Regarding surgical preparation methods overall, most learners and faculty selected reading (90% versus 78%, p = NS), and fewer respondents reported preferring videos (64% versus 44%, p = NS). Faculty more often use peer consultation (31% versus 50%, p YouTube (86%). Learners and faculty use different video sources. Learners use YouTube and Surgical Council on Resident Education (SCORE) Portal more than faculty (YouTube: 95% versus 73%, p YouTube was the preferred source. Posting surgical videos to YouTube may allow for maximal access to learners who are preparing for surgical cases. Copyright © 2016 Association of Program Directors in Surgery.

  14. Interactive, open source, travel time scenario modelling: tools to facilitate participation in health service access analysis.

    Fisher, Rohan; Lassa, Jonatan

    2017-04-18

    Modelling travel time to services has become a common public health tool for planning service provision but the usefulness of these analyses is constrained by the availability of accurate input data and limitations inherent in the assumptions and parameterisation. This is particularly an issue in the developing world where access to basic data is limited and travel is often complex and multi-modal. Improving the accuracy and relevance in this context requires greater accessibility to, and flexibility in, travel time modelling tools to facilitate the incorporation of local knowledge and the rapid exploration of multiple travel scenarios. The aim of this work was to develop simple open source, adaptable, interactive travel time modelling tools to allow greater access to and participation in service access analysis. Described are three interconnected applications designed to reduce some of the barriers to the more wide-spread use of GIS analysis of service access and allow for complex spatial and temporal variations in service availability. These applications are an open source GIS tool-kit and two geo-simulation models. The development of these tools was guided by health service issues from a developing world context but they present a general approach to enabling greater access to and flexibility in health access modelling. The tools demonstrate a method that substantially simplifies the process for conducting travel time assessments and demonstrate a dynamic, interactive approach in an open source GIS format. In addition this paper provides examples from empirical experience where these tools have informed better policy and planning. Travel and health service access is complex and cannot be reduced to a few static modeled outputs. The approaches described in this paper use a unique set of tools to explore this complexity, promote discussion and build understanding with the goal of producing better planning outcomes.

  17. Datafication and empowerment: How the open data movement re-articulates notions of democracy, participation, and journalism

    Directory of Open Access Journals (Sweden)

    Stefan Baack

    2015-07-01

    Full Text Available This article shows how activists in the open data movement re-articulate notions of democracy, participation, and journalism by applying practices and values from open source culture to the creation and use of data. Focusing on the Open Knowledge Foundation Germany and drawing from a combination of interviews and content analysis, it argues that this process leads activists to develop new rationalities around datafication that can support the agency of datafied publics. Three modulations of open source are identified: First, by regarding data as a prerequisite for generating knowledge, activists transform the sharing of source code to include the sharing of raw data. Sharing raw data should break the interpretative monopoly of governments and would allow people to make their own interpretation of data about public issues. Second, activists connect this idea to an open and flexible form of representative democracy by applying the open source model of participation to political participation. Third, activists acknowledge that intermediaries are necessary to make raw data accessible to the public. This leads them to an interest in transforming journalism to become an intermediary in this sense. At the same time, they try to act as intermediaries themselves and develop civic technologies to put their ideas into practice. The article concludes with suggesting that the practices and ideas of open data activists are relevant because they illustrate the connection between datafication and open source culture and help to understand how datafication might support the agency of publics and actors outside big government and big business.

    In this article we explore the ethical issues raised by permitting patients to pay for participation (P4) in clinical trials, and discuss whether there are any categorical objections to this practice. We address key considerations concerning payment for participation in trials, including patient autonomy, risk/benefit and justice, taking account of two previous critiques of the ethics of P4. We conclude that such trials could be ethical under certain strict conditions, but only if other potential sources of funding have first been explored or are unavailable.

    2010-01-01

    Abstract Objective: To (1) search the English-language literature for original research addressing the effect of cryotherapy on joint position sense (JPS) and (2) make recommendations regarding how soon healthy athletes can safely return to participation after cryotherapy. Data Sources: We performed an exhaustive search for original research using the AMED, CINAHL, MEDLINE, and SportDiscus databases from 1973 to 2009 to gather information on cryotherapy and JPS. Key words used were cryotherapy and proprioception, cryotherapy and joint position sense, cryotherapy, and proprioception. Study Selection: The inclusion criteria were (1) the literature was written in English, (2) participants were human, (3) an outcome measure included JPS, (4) participants were healthy, and (5) participants were tested immediately after a cryotherapy application to a joint. Data Extraction: The means and SDs of the JPS outcome measures were extracted and used to estimate the effect size (Cohen d) and associated 95% confidence intervals for comparisons of JPS before and after a cryotherapy treatment. The numbers, ages, and sexes of participants in all 7 selected studies were also extracted. Data Synthesis: The JPS was assessed in 3 joints: ankle (n  =  2), knee (n  =  3), and shoulder (n  =  2). The average effect size for the 7 included studies was modest, with effect sizes ranging from −0.08 to 1.17, with a positive number representing an increase in JPS error. The average methodologic score of the included studies was 5.4/10 (range, 5–6) on the Physiotherapy Evidence Database scale. Conclusions: Limited and equivocal evidence is available to address the effect of cryotherapy on proprioception in the form of JPS. Until further evidence is provided, clinicians should be cautious when returning individuals to tasks requiring components of proprioceptive input immediately after a cryotherapy treatment.

    In the current research, we examined whether re-inclusion (i.e. the change from a previous state of exclusion to a new state of inclusion) was perceived differently by people with individualistic and collectivistic cultural backgrounds. Individualists (German and Austrian participants) but not collectivists (Chinese participants) experienced re-inclusion differently than continued inclusion: While collectivistic participants did not differentiate between both kinds of inclusion, individualistic participants showed reduced fulfilment of their psychological needs under re-inclusion compared to continued inclusion. The results moreover revealed that only participants from individualistic cultures expressed more feelings of exclusion when re-included than when continually included. These exclusionary feelings partially mediated the relationship between the different states of inclusion and basic need fulfilment. © 2014 International Union of Psychological Science.

    1994-08-01

    Effective human resources management has been identified as one of four critical success factors in the Department of Energy Strategic Plan. The Plan states relative to this factor: ``The Department seeks greater alignment of resources with agency priorities and increased diversification of the workforce, including gender, ethnicity, age, and skills. This diversification will bring new thinking and perspectives that heretofore have not had a voice in departmental decision-making.`` This Guide has been developed as a key tool to assist Department of Energy management and administrative staff in achieving Goal 2 of this critical success factor, which is to ``Ensure a diverse and talented workforce.`` There are numerous sources from which to recruit minorities, women and persons with disabilities. Applying creativity and proactive effort, using traditional and non-traditional approaches, and reaching out to various professional, academic and social communities will increase the reservoir of qualified candidates from which to make selections. In addition, outreach initiatives will undoubtedly yield further benefits such as a richer cultural understanding and diversity awareness. The resource listings presented in this Guide are offered to encourage active participation in the diversity recruitment process. This Guide contains resource listings by state for organizations in the following categories: (1) African American Recruitment Sources; (2) Asian American/Pacific Islander Recruitment Sources; (3) Hispanic Recruitment Sources; (4) Native American/Alaskan Native Recruitment Sources; (5) Persons with Disabilities Recruitment Sources; and (6) Women Recruitment Sources.

    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.

    2018-02-08

    Public and policy attention to female genital mutilation (FGM) in diaspora communities has increased in Europe, but research remains limited and misinformation abounds. As a first step to addressing these issues, this study explored FGM prevention and response interventions in Europe, using a scoping literature review and key informant interviews. A scoping study design was selected, using Arksey and O'Malley's six-stage scoping framework to review identified sources. Key informant interviews were used to inform and add depth to literature findings. Findings were summarised thematically, guided by the Scottish Government's '4Ps' framework for tackling violence against women (i.e. participation, prevention, protection, providing services). Seventy literature sources, of 1095 screened, plus 16 individual and 3 group interview sources were included. Several countries have developed promising interventions supporting FGM resistance and recovery. However, gaps remain including community participation, professional knowledge and linkages, and evaluation of approaches. This scoping review is an initial attempt to describe available primary evidence on European initiatives responding to FGM. Further research is required to determine whether interventions are effective, while policy and practice development must be shaped and driven by the experiences, needs, and views of affected communities.

  6. Beyond tokenistic participation: using representational artefacts to enable meaningful public participation in health service design.

    Science.gov (United States)

    Morrison, Cecily; Dearden, Andy

    2013-10-01

    A number of recent policies promote public participation in health service design. Yet, a growing literature has articulated a gap between policy aims and actual practice resulting in public participation becoming tokenistic. Drawing on theory from participatory design, we argue that choosing appropriate artefacts to act as representations can structure discussions between public participants and health professionals in ways that both groups find meaningful and valid. Through a case study of a service improvement project in outpatient services for older people, we describe three representational artefacts: emotion maps, stories, and tracing paper, and explain how they helped to mediate interactions between public participants and health professionals. We suggest that using such representational artefacts can provide an alternative approach to participation that stands in contrast to the current focus on the professionalisation of public participants. We conclude that including participatory designers in projects, to chose or design appropriate representational artefacts, can help to address the policy-practice gap of including public participants in health service design.

    The aim of the study was to explore community-dwelling stroke patients' perceived barriers to healthy-lifestyle participation for secondary disease prevention, as well as their preferred means for risk-reduction information dissemination and motivators to participation in healthy-lifestyle interventions. Four focus groups (5-6 stroke survivors per group) were defined from community support groups. Key questions addressed barriers to healthy-lifestyle adoption, preferred methods for receiving information and factors that would engage participants in a risk-reduction programme. Groups were audiotaped, transcribed verbatim and analysed for thematic content using a framework approach. Twenty-two participants, 12 men, 10 women, mean age 71.4 (53-87) years, were included in the study. Three overarching themes emerged as barriers to healthy-lifestyle participation: physical, mental and environmental. Exercise participation difficulties spread across all three themes; healthy eating and smoking cessation concentrated in environmental and mental dimensions. Talks (discussions) were noted as participants' preferred method of information provision. Risk-reduction programmes considered attractive were stroke specific, convenient and delivered by healthcare professionals and involved both social and exercise components. Many stroke patients appear unable to adopt healthy-lifestyle changes through advice alone because of physical, mental and environmental barriers. Risk-reduction programmes including interactive education should be specifically tailored to address barriers currently experienced and extend beyond the stroke survivor to others in their environment who influence lifestyle choices.

    This study was undertaken to identify water intake and source patterns among a population that resides in a hot, arid region on the US-Mexico border. A cross-sectional community-based survey was conducted among households in the neighbouring cities of El Paso, TX, USA and Ciudad Juárez, Chihuahua, Mexico to obtain data on the quantity and source of water consumed. The study was also designed to identify factors that impact water consumption patterns, including gender, demographics, socio-economic status, cultural characteristics, health status, types of occupations and residences, available water sources and outdoor temperature, among many others. Of all factors studied, outdoor air temperature was found to have the strongest impact upon water intake quantity. Specifically, among the survey participants, when the outdoor air temperature exceeded 90 °F, water consumption increased by 28 %. Additionally, it was found that participants in this region consumed approximately 50 % more water than the values reported in previous studies.

    The Bioinformatics Open Source Conference (BOSC) is organized by the Open Bioinformatics Foundation (OBF), a nonprofit group dedicated to promoting the practice and philosophy of open source software development and open science within the biological research community. Since its inception in 2000, BOSC has provided bioinformatics developers with a forum for communicating the results of their latest efforts to the wider research community. BOSC offers a focused environment for developers and users to interact and share ideas about standards; software development practices; practical techniques for solving bioinformatics problems; and approaches that promote open science and sharing of data, results, and software. BOSC is run as a two-day special interest group (SIG) before the annual Intelligent Systems in Molecular Biology (ISMB) conference. BOSC 2015 took place in Dublin, Ireland, and was attended by over 125 people, about half of whom were first-time attendees. Session topics included "Data Science;" "Standards and Interoperability;" "Open Science and Reproducibility;" "Translational Bioinformatics;" "Visualization;" and "Bioinformatics Open Source Project Updates". In addition to two keynote talks and dozens of shorter talks chosen from submitted abstracts, BOSC 2015 included a panel, titled "Open Source, Open Door: Increasing Diversity in the Bioinformatics Open Source Community," that provided an opportunity for open discussion about ways to increase the diversity of participants in BOSC in particular, and in open source bioinformatics in general. The complete program of BOSC 2015 is available online at http://www.open-bio.org/wiki/BOSC_2015_Schedule.

    Toll Gate Creek, in the west-central part of the Denver Basin, is a perennial stream in which concentrations of dissolved selenium have consistently exceeded the Colorado aquatic-life standard of 4.6 micrograms per liter. Recent studies of selenium in Toll Gate Creek identified the Denver lignite zone of the non-marine Cretaceous to Tertiary-aged (Paleocene) Denver Formation underlying the watershed as the geologic source of dissolved selenium to shallow ground-water and surface water. Previous work led to this study by the U.S. Geological Survey, in cooperation with the City of Aurora Utilities Department, which investigated geologic sources of selenium and selenium concentrations in the watershed. This report documents the occurrence of selenium-bearing rocks and groundwater within the Cretaceous- to Tertiary-aged Denver Formation in the west-central part of the Denver Basin, including the Toll Gate Creek watershed. The report presents background information on geochemical processes controlling selenium concentrations in the aquatic environment and possible geologic sources of selenium; the hydrogeologic setting of the watershed; selenium results from groundwater-sampling programs; and chemical analyses of solids samples as evidence that weathering of the Denver Formation is a geologic source of selenium to groundwater and surface water in the west-central part of the Denver Basin, including Toll Gate Creek. Analyses of water samples collected from 61 water-table wells in 2003 and from 19 water-table wells in 2007 indicate dissolved selenium concentrations in groundwater in the west-central Denver Basin frequently exceeded the Colorado aquatic-life standard and in some locations exceeded the primary drinking-water standard of 50 micrograms per liter. The greatest selenium concentrations were associated with oxidized groundwater samples from wells completed in bedrock materials. Selenium analysis of geologic core samples indicates that total selenium

    Children require special considerations for drug prescribing. Drug information summarized in a formulary containing drug monographs is essential for safe and effective prescribing. Currently, little is known about the information needs of those who prescribe and administer medicines to children. Our primary objective was to identify a list of important and relevant items to be included in a pediatric drug monograph. Following the establishment of an expert steering committee and an environmental scan of adult and pediatric formulary monograph items, 46 participants from 25 countries were invited to complete a 2-round Delphi survey. Questions regarding source of prescribing information and importance of items were recorded. An international consensus meeting to vote on and finalize the items list with the steering committee followed. Pediatric formularies are most commonly the first resource consulted for information on medication used in children by 31 Delphi participants. After the Delphi rounds, 116 items were identified to be included in a comprehensive pediatric drug monograph, including general information, adverse drug reactions, dosages, precautions, drug-drug interactions, formulation, and drug properties. Health care providers identified 116 monograph items as important for prescribing medicines for children by an international consensus-based process. This information will assist in setting standards for the creation of new pediatric drug monographs for international application and for those involved in pediatric formulary development.

    Microfluidic devices have the potential to automate and miniaturize biological experiments, but open-source sharing of device designs has lagged behind sharing of other resources such as software. Synthetic biologists have used microfluidics for DNA assembly, cell-free expression, and cell culture, but a combination of expense, device complexity, and reliance on custom set-ups hampers their widespread adoption. We present Metafluidics, an open-source, community-driven repository that hosts digital design files, assembly specifications, and open-source software to enable users to build, configure, and operate a microfluidic device. We use Metafluidics to share designs and fabrication instructions for both a microfluidic ring-mixer device and a 32-channel tabletop microfluidic controller. This device and controller are applied to build genetic circuits using standard DNA assembly methods including ligation, Gateway, Gibson, and Golden Gate. Metafluidics is intended to enable a broad community of engineers, DIY enthusiasts, and other nontraditional participants with limited fabrication skills to contribute to microfluidic research.

    A Human Research Ethics Committee (HREC) is required to scrutinise the protocols of clinical drug trials that recruit patients as participants. If the study involves exposing the participants to ionizing radiation the information provided to the participant should contain a radiation risk statement that is understandable by the Committee and the participant. The information that should be included in the risk statement is available from a variety of published sources and is discussed. The ARPANSA Code of Practice Exposure of Humans to Ionizing Radiation for Research Purposes (2005) states explicitly what the responsibilities of the researcher and the HREC are. Some research protocols do not provide the information required by good radiation protection practice and explicitly called for by the Code. Nine points (including: state that ionizing radiation is involved; that the radiation is additional to standard care; the effective dose to be received; the dose compared to natural background; the dose to the most exposed organs; a statement of risk; the benefits accruing from the exposure; ask the participant about previous exposures; name a contact person from whom information may be sought) that should be considered for inclusion in the participant information are presented and discussed. An example of a radiation risk statement is provided

    The incidence of sudden cardiac arrest during participation in sports activities remains unknown. Preparticipation screening programs aimed at preventing sudden cardiac arrest during sports activities are thought to be able to identify at-risk athletes; however, the efficacy of these programs remains controversial. We sought to identify all sudden cardiac arrests that occurred during participation in sports activities within a specific region of Canada and to determine their causes. In this retrospective study, we used the Rescu Epistry cardiac arrest database (which contains records of every cardiac arrest attended by paramedics in the network region) to identify all out-of-hospital cardiac arrests that occurred from 2009 through 2014 in persons 12 to 45 years of age during participation in a sport. Cases were adjudicated as sudden cardiac arrest (i.e., having a cardiac cause) or as an event resulting from a noncardiac cause, on the basis of records from multiple sources, including ambulance call reports, autopsy reports, in-hospital data, and records of direct interviews with patients or family members. Over the course of 18.5 million person-years of observation, 74 sudden cardiac arrests occurred during participation in a sport; of these, 16 occurred during competitive sports and 58 occurred during noncompetitive sports. The incidence of sudden cardiac arrest during competitive sports was 0.76 cases per 100,000 athlete-years, with 43.8% of the athletes surviving until they were discharged from the hospital. Among the competitive athletes, two deaths were attributed to hypertrophic cardiomyopathy and none to arrhythmogenic right ventricular cardiomyopathy. Three cases of sudden cardiac arrest that occurred during participation in competitive sports were determined to have been potentially identifiable if the athletes had undergone preparticipation screening. In our study involving persons who had out-of-hospital cardiac arrest, the incidence of sudden cardiac

    Objective Research suggests that some types of trauma research can be conducted safely with children ages 10 and older. The aim of this project was to learn more about potential risks or benefits of conducting research with younger children or with child disaster survivors, specifically about research that includes children providing trauma recollections. Method Fifty 8- to 12-year-old children who experienced a devastating tornado participated in an in-person interview that included both individual and joint (mother-child) recollections of their tornado experiences one year following exposure. These 50 children also rated three emotions at three timepoints and rated their perceptions (e.g., benefit and regret) of research post-participation. Children (N = 28) also participated in phone surveys three months later to assess persistent participation-related emotions and perceptions. Results Child reported emotions worsened from pre- to during participation; however, reports of emotions returned to pre-participation levels post-participation and remained so at the 3-month follow-up. Sixty-four percent of children reported at least some participation benefit and no participation regret immediately post-participation, as did 89.3% at the 3-month follow-up. Four percent of children reported some participation regret (no benefit) post-participation, and 0% three months later. No children requested to stop participating, and none required post-research connection with crisis services. Posttraumatic stress symptom severity, tornado exposure, and age were largely unrelated to child-reported emotions and perceptions of research. Conclusions Results indicate that carefully planned and executed disaster-related research that includes children providing recollections research can be conducted with preadolescents with little risk and some benefit.

    The application of a turnkey communication system for telepresence at station 9.8 of the Synchrotron Radiation Source, Daresbury, is described and demonstrated, including its use for inter-continental classroom instruction and user training. Station 9.8 is one of the most oversubscribed and high-throughput stations at the Synchrotron Radiation Source, Daresbury, whereby awarded experimental time is limited, data collections last normally no longer than an hour, user changeover is normally every 24 h, and familiarity with the station systems can be low. Therefore time lost owing to technical failures on the station has a dramatic impact on productivity. To provide 24 h support, the application of a turnkey communication system has been implemented, and is described along with additional applications including its use for inter-continental classroom instruction, user training and remote participation

    Full Text Available Background: It has been reported that South Africa has the highest number of people living with HIV worldwide, with more women being infected than men. Women living with HIV have been documented as experiencing various symptoms related to HIV and use various strategies to manage these symptoms. Objective: The objective of this study was to explore the sources and types of information regarding self-care symptom management strategies received by women living with HIV. Method: The study was conducted at an HIV clinic in an urban area of KwaZulu-Natal. Individual in-depth interviews were completed with 11 women who were living with HIV,exploring the sources of information received on how they manage the HIV- (and/or AIDS- related symptoms they experienced as well as the types of information received. The collecteddata were analysed using qualitative content analysis. Results: The participants identified various sources, which mainly included groups of people who provided them with information on how to manage their HIV-related symptoms, namely healthcare providers, their personal networks and the community. The different sources offered different types of information, including the use of medication, complementary treatments and self-comforting activities. Conclusion: The study highlights that participants used multiple sources to get information about how to manage the experienced symptoms related to HIV, namely, healthcare providers, family and friends as well as themselves. It is to be noted that each source provided a preferred type of information.

    Full Text Available Qatar is experiencing rapid population expansion with increasing demands on healthcare services for both acute and chronic conditions. Sourcing accurate information about health conditions is crucial, yet the methods used for sourcing health information in Qatar are currently unknown. Gaining a better understanding of the sources the Qatari population use to recognize and manage health and/or disease will help to develop strategies to educate individuals about existing and emerging health problems.To investigate the methods used by the Qatari population to source health information. We hypothesized that the Internet would be a key service used to access health information by the Qatari population.A researcher-led questionnaire was used to collect information from Qatari adults, aged 18-85 years. Participants were approached in shopping centers and public places in Doha, the capital city of Qatar. The questionnaire was used to ascertain information concerning demographics, health status, and utilization of health care services during the past year as well as sources of health information used.Data from a total of 394 eligible participants were included. The Internet was widely used for seeking health information among the Qatari population (71.1%. A greater proportion of Qatari females (78.7% reported searching for health-related information using the Internet compared to Qatari males (60.8%. Other commonly used sources were family and friends (37.8% and Primary Health Care Centers (31.2%. Google was the most commonly used search engine (94.8%. Gender, age and education levels were all significant predictors of Internet use for heath information (P<0.001 for all predictors. Females were 2.9 times more likely than males (P<0.001 and people educated to university or college level were 3.03 times more likely (P<0.001 to use the Internet for heath information.The Internet is a widely used source to obtain health-related information by the Qatari

The first release of the CSC includes information about 94,676 distinct X-ray sources detected in a subset of public Advanced CCD Imaging Spectrometer imaging observations from roughly the first eight years of the Chandra mission. This release of the catalog includes point and compact sources with observed spatial extents ∼<30''. The catalog (1) provides access to the best estimates of the X-ray source properties for detected sources, with good scientific fidelity, and directly supports scientific analysis using the individual source data; (2) facilitates analysis of a wide range of statistical properties for classes of X-ray sources; and (3) provides efficient access to calibrated observational data and ancillary data products for individual X-ray sources, so that users can perform detailed further analysis using existing tools. The catalog includes real X-ray sources detected with flux estimates that are at least 3 times their estimated 1σ uncertainties in at least one energy band, while maintaining the number of spurious sources at a level of ∼<1 false source per field for a 100 ks observation. For each detected source, the CSC provides commonly tabulated quantities, including source position, extent, multi-band fluxes, hardness ratios, and variability statistics, derived from the observations in which the source is detected. In addition to these traditional catalog elements, for each X-ray source the CSC includes an extensive set of file-based data products that can be manipulated interactively, including source images, event lists, light curves, and spectra from each observation in which a

  7. Source term reduction at DAEC (including stellite ball recycling)

    Smith, R.; Schebler, D.

    1995-01-01

    The Duane Arnold Energy Center was seeking methods to reduce dose rates from the drywell due to Co-60. Duane Arnold is known in the industry to have one of the highest drywell dose rates from the industry standardized 'BRAC' point survey. A prime method to reduce dose rates due to Co-60 is the accelerated replacement of stellite pins and rollers in control rod blades due to their high stellite (cobalt) content. Usually the cobalt content in alloys of stellite is greater than 60% cobalt by weight. During the RFO-12 refueling outage at Duane Arnold, all of the remaining cobalt bearing control rod blades were replaced and new stellite free control rod blades were installed in the core. This left Duane Arnold with the disposal of highly radioactive stellite pins and rollers. The processing of control rod blades for disposal is a very difficult evolution. First, the velocity limiter (a bottom portion of the component) and the highly radioactive upper stellite control rod blade ins and rollers are separated from the control rod blade. Next, the remainder of the control rod blade is processed (chopped and/or crushed) to aid packaging the waste for disposal. The stellite bearings are then often carefully placed in with the rest of the waste in a burial liner to provide shielding for disposal or more often are left as 'orphans' in the spent fuel pool because their high specific activity create shipping and packaging problems. Further investigation by the utility showed that the stellite balls and pins could be recycled to a source manufacturer rather than disposed of in a low-level burial site. The cost savings to the utility was on the order of $200,000 with a gross savings of $400,000 in savings in burial site charges. A second advantage of the recycling of the stellite pins and rollers was a reduction in control in radioactive waste shipments

    The roles of group participation and group performance feedback were examined as antecedents of group potency, i.e., beliefs shared among a work group's members about the general effectiveness of the work group. Also examined were how group participation and the congruence of the feedback received from different sources about performance predicted convergence in members' beliefs about group effectiveness. The sample comprised 61 work groups of professionals involved in Master in Business Administration (MBA) programs (284 participants). Mean group size was 4.6 members (SD = .58). 65% of participants were male, and 51% were between 30 and 40 years of age. Data were gathered at two measurement times. Increases in group participation were positively related to increases in group potency and the convergence in beliefs about group effectiveness among group members over time. Results supported the premise that group performance feedback is an antecedent of changes in group potency over time.

    Working conditions, including workplace safety, in global supply chains of products sold by transnational corporations have only marginally improved over the last 15 years despite the development of hundreds of corporate "codes of conduct," code monitoring systems, and an elaborate new "corporate social responsibility" industry. The two underlying reasons for the lack of significant change are: 1) a schizophrenic business model which fatally undermines "socially responsible" sourcing programs with unyielding dictates for the lowest possible production costs; and 2) the lack of any meaningful participation by shop-floor workers in plant safety programs. Only when trained, empowered, and active workers are an integral part of workplace safety programs will conditions improve over the long term.

    The purpose of this study was to identify those particular aspects of US Department of Energy (DOE) research participation programs for undergraduate and graduate students that are most associated with attracting and benefiting underrepresented minority students and encouraging them to pursue careers in science, engineering, and technology. A survey of selected former underrepresented minority participants, focus group analysis, and critical incident analysis serve as the data sources for this report. Data collected from underrepresented minority participants indicate that concerns expressed and suggestions made for conducting student research programs at DOE contractor facilities are not remarkably different from those made by all participants involved in such student research participation programs. With the exception of specific suggestions regarding recruitment, the findings summarized in this report can be interpreted to apply to all student research participants in DOE national laboratories. Clearly defined assignments, a close mentor-student association, good communication, and an opportunity to interact with other participants and staff are those characteristics that enhance any educational program and have positive impacts on career development.

    Human immunodeficiency virus clinical trials are increasingly being conducted in sub-Saharan Africa. There is a tension between the pressure to increase levels of research participation and the need to ensure informed consent and protection of participants' rights. Researchers need to be aware of the particular ethical issues that underpin Human immunodeficiency virus research conduct in low income settings. This necessitates hearing from those who have participated in research and who have direct experience of the research process. This review aimed to synthesize and present the best available evidence in relation to Human immunodeficiency virus research participation in sub-Saharan Africa, based on the views and experiences of research participants. The review included studies whose participants were current or former adult Human immunodeficiency virus research participants from sub-Saharan African countries. Views, experiences, attitudes, understandings, perceptions and perspectives of Human immunodeficiency virus research participants in sub-Saharan Africa. Types of studies: This review considered studies that focused on qualitative data, including, but not limited to, designs such as phenomenology, ethnography, grounded theory, action research and feminist research. A three-step search strategy was utilized.

    Full Text Available Background Oestrogen is the primary female sex hormone and has important functions in both female and male physiology. Recently oestrogen abuse among male gym participants had raised as it is considered to enhance gym performance and breast size. Aims This study assesses the prevalence of oestrogen use among male gym patrons in Saudi Arabia, their practice related to oestrogen abuse, and the profiles of users. Methods A cross-sectional study was conducted from February 2017 to May 2017 and included 4,860 male gym patrons. The participants were given a questionnaire with a total of 19 questions regarding socioeconomic information, knowledge and practices related to oestrogen, and lifestyle habits. Results The participants had a mean age of 28.6+6.2 years, 6.1 per cent of them abused oestrogen, and the most common forms used were ethinylestradiol (0.03mg and drospirenone (3mg. Furthermore, 80.7 per cent of the users used it before exercise only. Breast enlargement was the main reason for oestrogen use, and local drug stores were the main source. Compared to non-users, oestrogen users were older (P=0.322, reported lower incomes (P=0.395, were more likely to be active smokers (P=0.597, and had a longer duration of gym participation (P < 0.001. Conclusion The results indicate that 6.1 per cent of the surveyed male participants abused a combination of oestrogen and progesterone for breast enlargement, which was significantly more likely among males who had longer durations of gym participation.

    Many theoretical and research-based approaches suggest how to best use mentoring to enhance an undergraduate research program. The Institute for Broadening Participation's Pathways to Engineering and Pathways to Ocean Sciences projects synthesized a set of mentoring studies, theoretical sources, and other texts pertinent to undergraduate research program design into a suite of practical tools that includes an online mentoring manual, an online reference library of mentoring and diversity literature, and practical guides such as Using Social Media to Build Diversity in Your REU. The overall goal is to provide easy-to-access resources that can assist faculty and program directors in implementing or honing the mentoring elements in their research programs for undergraduates. IBP's Online Mentoring Manual addresses common themes, such as modeling, student self-efficacy, career development, retention and evaluation. The Online Diversity Reference Library provides a comprehensive, annotated selection of key policy documents, research studies, intervention studies, and other texts on broadening participation in science, technology, engineering and mathematics. IBP's suite of tools provides the theoretical underpinnings and research findings that can help leaders in education integrate site-appropriate mentoring elements into their educational programs. Program directors and faculty from a variety of program types and disciplines have benefitted from using the Manual and other resources. IBP continues the work of translating and synthesizing theory to practice and welcomes your participation and partnership in that effort.

    During September 7-11, 2000, CDC was notified by the Idaho Department of Health, the Los Angeles County Department of Health Services, and the GeoSentinel Global Surveillance Network of at least 20 cases of acute febrile illness in three countries; all ill patients had participated in the Eco-Challenge-Sabah 2000 multisport expedition race in Borneo, Malaysia, during August 21-September 3, 2000. Participants included athletes from 29 U.S. states and 26 countries. This report updates the ongoing investigation of this outbreak through December 2, which suggests that Leptospira were the cause of illness and that water from the Segama River was the primary source of infection. Participants in adventure sports and exotic tourism should be aware of potential exposure to unusual and emerging infectious agents.

    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.

    2012-02-01

    Assessments of whether patients with musculoskeletal disorders (MSDs) can participate in work mainly consist of case history, physical examinations, and self-reports. Performance-based measures might add value in these assessments. This study answers the question: how well do performance-based measures predict work participation in patients with MSDs? A systematic literature search was performed to obtain longitudinal studies that used reliable performance-based measures to predict work participation in patients with MSDs. The following five sources of information were used to retrieve relevant studies: PubMed, Embase, AMA Guide to the Evaluation of Functional Ability, references of the included papers, and the expertise and personal file of the authors. A quality assessment specific for prognostic studies and an evidence synthesis were performed. Of the 1,230 retrieved studies, eighteen fulfilled the inclusion criteria. The studies included 4,113 patients, and the median follow-up period was 12 months. Twelve studies took possible confounders into account. Five studies were of good quality and thirteen of moderate quality. Two good-quality and all thirteen moderate-quality studies (83%) reported that performance-based measures were predictive of work participation. Two good-quality studies (11%) reported both an association and no association between performance-based measures and work participation. One good-quality study (6%) found no effect. A performance-based lifting test was used in fourteen studies and appeared to be predictive of work participation in thirteen studies. Strong evidence exists that a number of performance-based measures are predictive of work participation in patients with MSDs, especially lifting tests. Overall, the explained variance was modest.

    2017-12-01

    Field measurements were conducted in Nepal and in the Indonesian province of Central Kalimantan to improve characterization of trace gases and aerosols emitted by undersampled combustion sources. The sources targeted included cooking with a variety of stoves, garbage burning, crop residue burning, and authentic peat fires. Trace gas and aerosol emissions were studied using a land-based Fourier transform infrared spectrometer, whole air sampling, photoacoustic extinctiometers (405 and 870nm), and filter samples that were analyzed off-line. These measurements were used to calculate fuel-based emission factors (EFs) for up to 90 gases, PM2.5, and PM2.5 constituents. The aerosol optical data measured included EFs for the scattering and absorption coefficients, the single scattering albedo (at 870 and 405 nm), as well as the absorption Ångström exponent. The emissions varied significantly by source, although light absorption by both brown and black carbon (BrC and BC, respectively) was important for all non-peat sources. For authentic peat combustion, the emissions of BC were negligible and absorption was dominated by organic aerosol. The field results from peat burning were in reasonable agreement with recent lab measurements of smoldering Kalimantan peat and compare well to the limited data available from other field studies. The EFs can be used with estimates of fuel consumption to improve regional emissions inventories and assessments of the climate and health impacts of these undersampled sources.

    The lack of controlled trials in the relationship between participation in adapted sports, and quality of life (QoL) and life satisfaction in people with physical disabilities encouraged us to consider conducting this study. The aim of this study was to compare the QoL and life satisfaction scores between people with physical disabilities who participated in adapted sports and those who did not participate in any adapted sports. This cross-sectional controlled study included 60 individuals with physical disabilities (paraplegia and amputee). Participants were divided into two groups based on sports participation and non-sports participation. Group one included 30 disabled elite athletes who participated in adapted sports. The control group included 30 disabled individuals not involved in any adapted sports. We compared scores on the World Health Organization Quality-of-Life Scale (WHOQoL-BREF) and the Satisfaction With Life Scale (SWLS) between the two groups. Participation in the community and QoL was examined as a reflection of participant's priority on sports participation. We found that WHOQoL-BREF physical, psychological, and social domain scores were significantly higher in group one than in the control group (p sports had significantly higher QoL and life satisfaction scores compared to people with physical disabilities not involved in any adapted sports.

    Leon, Andres E.; Solsona, Jorge A.; Busada, Claudio; Chiacchiarini, Hector; Valla, Maria Ines

    2009-01-01

    In this paper a new control strategy for voltage-source converters (VSC) is introduced. The proposed strategy consists of a nonlinear feedback controller based on feedback linearization plus a feedforward compensation of the estimated load current. In our proposal an energy function and the direct-axis current are considered as outputs, in order to avoid the internal dynamics. In this way, a full linearization is obtained via nonlinear transformation and feedback. An estimate of the load current is feedforwarded to improve the performance of the whole system and to diminish the capacitor size. This estimation allows to obtain a more rugged and cheaper implementation. The estimate is calculated by using a nonlinear reduced-order observer. The proposal is validated through different tests. These tests include performance in presence of switching frequency, measurement filters delays, parameters uncertainties and disturbances in the input voltage.

    2017-08-07

    Children with cerebral palsy (CP) participate in leisure-time physical activities (PA) less often, with less intensity and reduced diversity than their typically developing peers. Participation in leisure-time physical activities may be an important source of habitual physical activity (HPA) for children with CP, who as a group have lower levels of HPA and increased sedentary time compared with their typically developing peers. The proposed study aims to compare the efficacy of a participation focused therapy (ParticiPAte CP) to usual care in a pragmatic, randomised waitlist controlled trial. Thirty-six children with CP (18 in each group), classified as Gross Motor Function Classification System levels I to III, aged between 8 and 12 years will be recruited across South East Queensland, Australia. Children will be randomised to receive either ParticiPAte CP or waitlist usual care using concealed allocation. ParticiPAte CP is an individually tailored, goal-directed intervention model of pragmatic participation-focused therapy using a toolbox of evidence-based strategies in the treatment of children with CP. This will include goal-setting; identification of barriers and facilitators to participation goals, strategy formation and planning and communication guided by principles of Self-Determination Theory using strategies of Motivational Interviewing. The intervention comprises 8 weekly sessions of 1 hour duration conducted by a physiotherapist in the child's home or community.

    2013-02-01

    The long history of persuasion research shows how to change explicit, self-reported evaluations through direct appeals. At the same time, research on how to change implicit evaluations has focused almost entirely on techniques of retraining existing evaluations or manipulating contexts. In five studies, we examined whether direct appeals can change implicit evaluations in the same way as they do explicit evaluations. In five studies, both explicit and implicit evaluations showed greater evidence of persuasion following information presented by a highly credible source than a source low in credibility. Whereas cognitive load did not alter the effect of source credibility on explicit evaluations, source credibility had an effect on the persuasion of implicit evaluations only when participants were encouraged and able to consider information about the source. Our findings reveal the relevance of persuasion research for changing implicit evaluations and provide new ideas about the processes underlying both types of evaluation.

    2017-02-10

    Open source modeling and optimization tools for planning The existing tools and software used for planning and analysis in California are either expensive, difficult to use, or not generally accessible to a large number of participants. These limitations restrict the availability of participants for larger scale energy and grid studies in the state. The proposed initiative would build upon federal and state investments in open source software, and create and improve open source tools for use in the state planning and analysis activities. Computational analysis and simulation frameworks in development at national labs and universities can be brought forward to complement existing tools. An open source platform would provide a path for novel techniques and strategies to be brought into the larger community and reviewed by a broad set of stakeholders.

    2016-05-01

    Full Text Available Background: Athletes obtain nutrition information from a number of sources, with some being more accurate than others.  Little is known about athletes’ perceptions of utilizing Certified Athletic Trainers (ATs as a primary source of information. Objective: We sought to 1 examine the primary sources of nutrition information among a group of United States collegiate athletes and 2 understand athletes’ perceptions regarding utilization of their ATs as primary sources of nutrition information. Methods: Participants (Division II university athletes completed an online questionnaire (n=155;n=58 males, n=97 females assessing demographic information and ranked primary sources of nutrition information, and participated in focus groups (n=26;n=18 women, n=8 men to better understand barriers/perceptions for using their ATs for nutrition information. Mean+SD ranking were calculated for all sources. Mann Whitney-U analyses were used to identify differences in rank order nutrition sources between genders and years of collegiate experience. Semi-structured focus groups were transcribed, coded, and themes were identified regarding barriers to utilizing ATs for nutrition-related information. Results: Parents (3.54±2.38 and the internet (3.69±2.29 had the highest mean ranks.  ATs were least often ranked as the number one nutrition source (7.5%, among all sources provided.  Barriers to utilizing ATs for nutritional information included discomfort, nutrition information not being within the scope of practice, lack of knowledge, the athletic trainer not caring, and lack of time. Conclusions: Participants reported utilizing ATs less than previous research indicates. Continuing education may be needed to improve the efficacy of ATs in addressing nutritional issues and being seen as a credible and accessible source. Keywords: Diet, Athlete perceptions, Barriers

    Full Text Available This paper builds on the findings of a workshop held at the 2015 International Conference on Digital Preservation (iPRES, entitled, “Using Open-Source Tools to Fulfill Digital Preservation Requirements” (OSS4PRES hereafter. This day-long workshop brought together participants from across the library and archives community, including practitioners, proprietary vendors, and representatives from open-source projects. The resulting conversations were surprisingly revealing: while OSS’ significance within the preservation landscape was made clear, participants noted that there are a number of roadblocks that discourage or altogether prevent its use in many organizations. Overcoming these challenges will be necessary to further widespread, sustainable OSS adoption within the digital preservation community. This article will mine the rich discussions that took place at OSS4PRES to (1 summarize the workshop’s key themes and major points of debate, (2 provide a comprehensive analysis of the opportunities, gaps, and challenges that using OSS entails at a philosophical, institutional, and individual level, and (3 offer a tangible set of recommendations for future work designed to broaden community engagement and enhance the sustainability of open source initiatives, drawing on both participants’ experience as well as additional research.

    Schilling, A.H.; Nealey, S.M.

    1979-04-01

    The recent report of the Interagency Review Group (IRG) on Nuclear Waste Management formalized what has become increasingly clear in recent years: public participation in nuclear waste management decisions is a fact of life and will be more emphasized in the future than in the past. The purpose of this paper is to discuss, and stimulate discussion, of major issues which must be considered before attempting to design and implement a program to encourage public participation in this complex and sensitive area. Public participation is a term with many possible meanings. The term is used here to stand for a very wide range of activities including: providing information about programs and intended actions, seeking advice or permission from state or local officials, conducting public meetings to announce plans and receive reactions, conducting hearings, establishing consultative panels of outside experts or special interest group members, and even conducting surveys of public opinion and concern. This paper is not a proposal or a set of specific recommendations, but a stimulus to thought and discussion. It was prepared with DOE's role in waste management in mind, and benefits from the authors' opportunity to observe the public participation process in this topic area to data. The paper is organized into four sections that take account of (1) past participation efforts, (2) why public participation is necessary and what might be gained by it, (3) considerations in designing a participation program, and (4) major principles involved in conducting a public participation program, including a brief review of participation procedures

    To conduct a federally funded study that examines the acquisition, implementation and operation of open source electronic health records (EHR) within safety net medical settings, such as federally qualified health centers (FQHC). The study was conducted by the National Opinion Research Center (NORC) at the University of Chicago from April to September 2010. The NORC team undertook a comprehensive environmental scan, including a literature review, a dozen key informant interviews using a semistructured protocol, and a series of site visits to West Virginia, California and Arizona FQHC that were currently using an open source EHR. Five of the six sites that were chosen as part of the study found a number of advantages in the use of their open source EHR system, such as utilizing a large community of users and developers to modify their EHR to fit the needs of their provider and patient communities, and lower acquisition and implementation costs as compared to a commercial system. Despite these advantages, many of the informants and site visit participants felt that widespread dissemination and use of open source was restrained due to a negative connotation regarding this type of software. In addition, a number of participants stated that there is a necessary level of technical acumen needed within the FQHC to make an open source EHR effective. An open source EHR provides advantages for FQHC that have limited resources to acquire and implement an EHR, but additional study is needed to evaluate its overall effectiveness.

    The model S700 Axxent electronic brachytherapy source by Xoft, Inc., was characterized by Rivard et al. in 2006. Since then, the source design was modified to include a new insert at the source tip. Current study objectives were to establish an accurate source model for simulation purposes, dosimetrically characterize the new source and obtain its TG-43 brachytherapy dosimetry parameters, and determine dose differences between the original simulation model and the current model S700 source design. Design information from measurements of dissected model S700 sources and from vendor-supplied CAD drawings was used to aid establishment of an updated Monte Carlo source model, which included the complex-shaped plastic source-centering insert intended to promote water flow for cooling the source anode. These data were used to create a model for subsequent radiation transport simulations in a water phantom. Compared to the 2006 simulation geometry, the influence of volume averaging close to the source was substantially reduced. A track-length estimator was used to evaluate collision kerma as a function of radial distance and polar angle for determination of TG-43 dosimetry parameters. Results for the 50 kV source were determined every 0.1 cm from 0.3 to 15 cm and every 1° from 0° to 180°. Photon spectra in water with 0.1 keV resolution were also obtained from 0.5 to 15 cm and polar angles from 0° to 165°. Simulations were run for 10(10) histories, resulting in statistical uncertainties on the transverse plane of 0.04% at r = 1 cm and 0.06% at r = 5 cm. The dose-rate distribution ratio for the model S700 source as compared to the 2006 model exceeded unity by more than 5% for roughly one quarter of the solid angle surrounding the source, i.e., θ ≥ 120°. The radial dose function diminished in a similar manner as for an (125)I seed, with values of 1.434, 0.636, 0.283, and 0.0975 at 0.5, 2, 5, and 10 cm, respectively.

    The increase of distributed energy resources, mainly based on renewable sources, requires new solutions that are able to deal with this type of resources' particular characteristics (namely, the renewable energy sources intermittent nature). The smart grid concept is increasing its consensus as the most suitable solution to facilitate the small players' participation in electric power negotiations while improving energy efficiency. The opportunity for players' participation in multiple energy negotiation environments (smart grid negotiation in addition to the already implemented market types, such as day-ahead spot markets, balancing markets, intraday negotiations, bilateral contracts, forward and futures negotiations, and among other) requires players to take suitable decisions on whether to, and how to participate in each market type. This paper proposes a portfolio optimization methodology, which provides the best investment profile for a market player, considering different market opportunities. The amount of power that each supported player should negotiate in each available market type in order to maximize its profits, considers the prices that are expected to be achieved in each market, in different contexts. The price forecasts are performed using artificial neural networks, providing a specific database with the expected prices in the different market types, at each time. This database is then used as input by an evolutionary particle swarm optimization process, which originates the most advantage participation portfolio for the market player. The proposed approach is tested and validated with simulations performed in multiagent simulator of competitive electricity markets, using real electricity markets data from the Iberian operator-MIBEL.

    Full Text Available The committed participation of the inhabitants in diverse Venezuelan communities is fundamental in the search of solution to environmental problems that they face in the daily life; in the face of this reality, studies based on Participant Action Research were addressed, through a review and documentary analysis of four works related to community participation, carried out in the state of Lara. For this, the following question was asked: ¿What was the achievement in the solution of environmental problems in the communities, reported through the master's degree works oriented under participant action research and presented to Yacambú University in 2011-2013? A qualitative approach is used, approaching the information according to the stages suggested by Arias (2012: Search of sources, initial reading of documents, preparation of the preliminary scheme, data collection, analysis and interpretation of the information, formulation of the final scheme, introduction and conclusions, final report. It begins with the definition of the units of analysis and inquiry of the literature, through theoretical positions, concepts and contributions on: participant action research, participation and environmental education, to culminate with the analysis and interpretation of the information and the conclusions of this investigation. For the collection of the data, the bibliographic records were used with the purpose of organizing the information on the researches consulted, and of summary for the synthesis of the documents. It was concluded that, in the analyzed degree works, the purpose of the IAP was fulfilled, which consisted in the transformation of the problem-situation, which allowed the IAP to become the propitious scenario to promote environmental participation and education not formal.

    Full Text Available Abstract Background Complete and accurate ascertainment of mortality is critically important in any longitudinal study. Tracking of mortality is particularly essential among US military members because of unique occupational exposures (e.g., worldwide deployments as well as combat experiences. Our study objectives were to describe the early mortality experience of Panel 1 of the Millennium Cohort, consisting of participants in a 21-year prospective study of US military service members, and to assess data sources used to ascertain mortality. Methods A population-based random sample (n = 256,400 of all US military service members on service rosters as of October 1, 2000, was selected for study recruitment. Among this original sample, 214,388 had valid mailing addresses, were not in the pilot study, and comprised the group referred to in this study as the invited sample. Panel 1 participants were enrolled from 2001 to 2003, represented all armed service branches, and included active-duty, Reserve, and National Guard members. Crude death rates, as well as age- and sex-adjusted overall and age-adjusted, category-specific death rates were calculated and compared for participants (n = 77,047 and non-participants (n = 137,341 based on data from the Social Security Administration Death Master File, Department of Veterans Affairs (VA files, and the Department of Defense Medical Mortality Registry, 2001-2006. Numbers of deaths identified by these three data sources, as well as the National Death Index, were compared for 2001-2004. Results There were 341 deaths among the participants for a crude death rate of 80.7 per 100,000 person-years (95% confidence interval [CI]: 72.2,89.3 compared to 820 deaths and a crude death rate of 113.2 per 100,000 person-years (95% CI: 105.4, 120.9 for non-participants. Age-adjusted, category-specific death rates highlighted consistently higher rates among study non-participants. Although there were advantages and

    Internet communication advances provide new opportunities to assemble individuals with rare diseases to online patient registries from wide geographic areas for research. However, there is little published information on the efficacy of different recruitment methods. Here we describe recruitment patterns and the characteristics of individuals with the self-identified autosomal dominant genetic disorder neurofibromatosis type 1 (NF1) who participated in an online patient registry during the 1-year period from 1/1/2012 to 12/31/2012. We employed four main mechanisms to alert potential participants to the registry: (1) Facebook and Google advertising, (2) government and academic websites, (3) patient advocacy groups, and (4) healthcare providers. Participants reported how they first heard about the registry through an online questionnaire. During the 1-year period, 880 individuals participated in the registry from all 50 U.S. States, the District of Columbia, Puerto Rico, and 39 countries. Facebook and Google were reported as referral sources by the highest number of participants (n=550, 72% Facebook), followed by healthcare providers (n=74), and government and academic websites (n=71). The mean participant age was 29±18 years and most participants reported White race (73%) and female sex (62%) irrespective of reported referral source. Internet advertising, especially through Facebook, resulted in efficient enrollment of large numbers of individuals with NF1. Our study demonstrates the potential utility of this approach to assemble individuals with a rare disease from across the world for research studies. © 2014 Wiley Periodicals, Inc.

    2001-12-01

    Since 1971, the American Geological Institute (AGI) Minority Participation Program (MPP) has supported scholarships for underrepresented minorities in the geosciences at the undergraduate and graduate levels. Some of our MPP scholars have gone on to hugely successful careers in the geosciences. MPP scholars include corporate leaders, university professors, a NASA scientist-astronaut and a National Science Foundation (NSF) CAREER awardee. Yet as ethnic minorities continue to be underrepresented in the geosciences, AGI plans to expand its efforts beyond its traditional undergraduate and graduate scholarships to include diversity programs for secondary school geoscience teacher internships, undergraduate research travel support, and doctoral research fellowships. Funding for the MPP has come from multiple sources, including industry, scientific societies, individuals, and during the last 10 years, the NSF. College-level students apply for the MPP awards or award renewals, and the MPP Advisory Committee selects scholarship recipients based upon student academic performance, financial need, and potential for success as a geoscience professional. Mentoring is a long-standing hallmark of the AGI MPP. Every AGI MPP scholar is assigned a professional geoscientist as a mentor. The mentor is responsible for regular personal contacts with MPP scholars. The MPP Advisory Committee aims to match the profession of the mentor with the scholar's academic interest. Throughout the year, mentors and scholars communicate about possible opportunities in the geosciences such as internships, participation in symposia, professional society meetings, and job openings. Mentors have also been active in helping younger students cope with the major changes involved in relocating to a new region of the country or a new college culture. We believe that AGI is well-positioned to advance diversity in the geosciences through its unique standing as the major professional organization in the

    The Radiation Sources Working Group addressed advanced concepts for the generation of RF energy to power advanced accelerators. The focus of the working group included advanced sources and technologies above 17 GHz. The topics discussed included RF sources above 17 GHz, pulse compression techniques to achieve extreme peak power levels, components technology, technology limitations and physical limits, and other advanced concepts. RF sources included gyroklystrons, magnicons, free-electron masers, two beam accelerators, and gyroharmonic and traveling wave devices. Technology components discussed included advanced cathodes and electron guns, high temperature superconductors for producing magnetic fields, RF breakdown physics and mitigation, and phenomena that impact source design such as fatigue in resonant structures due to RF heating. New approaches for RF source diagnostics located internal to the source were discussed for detecting plasma and beam phenomena existing in high energy density electrodynamic systems in order to help elucidate the reasons for performance limitations

  10. A revised dosimetric characterization of the model S700 electronic brachytherapy source containing an anode-centering plastic insert and other components not included in the 2006 model

    2015-01-01

    Purpose: The model S700 Axxent electronic brachytherapy source by Xoft, Inc., was characterized by Rivard et al. in 2006. Since then, the source design was modified to include a new insert at the source tip. Current study objectives were to establish an accurate source model for simulation purposes, dosimetrically characterize the new source and obtain its TG-43 brachytherapy dosimetry parameters, and determine dose differences between the original simulation model and the current model S700 source design. Methods: Design information from measurements of dissected model S700 sources and from vendor-supplied CAD drawings was used to aid establishment of an updated Monte Carlo source model, which included the complex-shaped plastic source-centering insert intended to promote water flow for cooling the source anode. These data were used to create a model for subsequent radiation transport simulations in a water phantom. Compared to the 2006 simulation geometry, the influence of volume averaging close to the source was substantially reduced. A track-length estimator was used to evaluate collision kerma as a function of radial distance and polar angle for determination of TG-43 dosimetry parameters. Results for the 50 kV source were determined every 0.1 cm from 0.3 to 15 cm and every 1° from 0° to 180°. Photon spectra in water with 0.1 keV resolution were also obtained from 0.5 to 15 cm and polar angles from 0° to 165°. Simulations were run for 10 10 histories, resulting in statistical uncertainties on the transverse plane of 0.04% at r = 1 cm and 0.06% at r = 5 cm. Results: The dose-rate distribution ratio for the model S700 source as compared to the 2006 model exceeded unity by more than 5% for roughly one quarter of the solid angle surrounding the source, i.e., θ ≥ 120°. The radial dose function diminished in a similar manner as for an 125 I seed, with values of 1.434, 0.636, 0.283, and 0.0975 at 0.5, 2, 5, and 10 cm, respectively. The radial dose function

    The purpose of this study is to describe the reasons 88 Latinas with breast cancer selected specific supportive others to participate in an 8-week psychosocial intervention. Participants were asked one open-ended question during the baseline assessment for a larger clinical trial: "Could you tell me more about why you selected [insert name] to participate in the study with you?" A content analysis of the responses found three thematic categories: source of informational or emotional support, concern for the informal caregiver's welfare, and special characteristics or qualities of the informal caregiver. These findings reflected both the cultural value of familism, the woman's role as caregiver to the family ( marianismo), and the man's role of provider ( machismo). Findings provide support for including the supportive person identified by the patient during a health crisis rather than the provider suggesting who that should be. Psychosocial services designed and implemented through such a cultural lens are more likely to be successful.

    One of the cornerstones of the R system for statistical computing is the multitude of packages contributed by numerous package authors. This amount of packages makes an extremely broad range of statistical techniques and other quantitative methods freely available. Thus far, no empirical study has investigated psychological factors that drive authors to participate in the R project. This article presents a study of R package authors, collecting data on different types of participation (number of packages, participation in mailing lists, participation in conferences), three psychological scales (types of motivation, psychological values, and work design characteristics), and various socio-demographic factors. The data are analyzed using item response models and subsequent generalized linear models, showing that the most important determinants for participation are a hybrid form of motivation and the social characteristics of the work design. Other factors are found to have less impact or influence only specific aspects of participation.

  15. ERP correlates of source memory: unitized source information increases familiarity-based retrieval.

    Source memory tests typically require subjects to make decisions about the context in which an item was encoded and are thought to depend on recollection of details from the study episode. Although it is generally believed that familiarity does not contribute to source memory, recent behavioral studies have suggested that familiarity may also support source recognition when item and source information are integrated, or "unitized," during study (Diana, Yonelinas, and Ranganath, 2008). However, an alternative explanation of these behavioral findings is that unitization affects the manner in which recollection contributes to performance, rather than increasing familiarity-based source memory. To discriminate between these possibilities, we conducted an event-related potential (ERP) study testing the hypothesis that unitization increases the contribution of familiarity to source recognition. Participants studied associations between words and background colors using tasks that either encouraged or discouraged unitization. ERPs were recorded during a source memory test for background color. The results revealed two distinct neural correlates of source recognition: a frontally distributed positivity that was associated with familiarity-based source memory in the high-unitization condition only and a parietally distributed positivity that was associated with recollection-based source memory in both the high- and low-unitization conditions. The ERP and behavioral findings provide converging evidence for the idea that familiarity can contribute to source recognition, particularly when source information is encoded as an item detail.

    2013-10-01

    This study examined a three-step adaptation of the Theory of Planned Behaviour (TPB) applied to the intention of consumers to purchase sustainably sourced food. The sample consisted of 137 participants, of which 109 were female, who were recruited through a farmers market and an organic produce outlet in an Australian capital city. Participants completed an online questionnaire containing the TPB scales of attitude, subjective norms, perceived behavioural control and intention; measures of positive moral attitude and ethical self identity; and food choice motives. Hierarchical multiple regression was used to examine the predictive utility of the TPB in isolation (step 1) and the TPB expanded to include the constructs of moral attitude and ethical self-identity (step 2). The results indicated the expansion of the TPB to include these constructs added significantly to the predictive model measuring intention to purchase sustainably sourced food. The third step in the adaptation utilised this expanded TPB model and added a measure of retail channel (where consumers reported buying fresh produce) and 9 food choice motives, in order to assess the predictive utility of the inclusion of choice motivations in this context. Of the 8 food choice motives examined, only health and ethical values significantly predicted intention to purchase sustainably sourced food. However, with the addition of food choice motives, ethical self-identity was no longer a significant predictor of intention to purchase sustainably sourced food. Overall the adapted TPB model explained 76% of the variance in intention to purchase sustainably sourced food. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Although people are generally interested in how the brain functions, neuroscience education for the public is hampered by a lack of low cost and engaging teaching materials. To address this, we developed an open-source tool, the SpikerBox, which is appropriate for use in middle/high school educational programs and by amateurs. This device can be used in easy experiments in which students insert sewing pins into the leg of a cockroach, or other invertebrate, to amplify and listen to the electrical activity of neurons. With the cockroach leg preparation, students can hear and see (using a smartphone oscilloscope app we have developed the dramatic changes in activity caused by touching the mechanosensitive barbs. Students can also experiment with other manipulations such as temperature, drugs, and microstimulation that affect the neural activity. We include teaching guides and other resources in the supplemental materials. These hands-on lessons with the SpikerBox have proven to be effective in teaching basic neuroscience.

    This study aims to examine whether the effects of internet interventions for depression generalise to participants recruited in clinical settings. This study uses subgroup analysis of the results of a randomised, controlled, single-blind trial. The study takes place in five diagnostic centres in Germany. A total of 1013 people with mild to moderate depressive symptoms were recruited from clinical sources as well as internet forums, statutory insurance companies and other sources. This study uses either care-as-usual alone (control) or a 12-week internet intervention (Deprexis) plus usual care (intervention). The primary outcome measure was self-rated depression severity (Patient Health Questionnaire-9) at 3 months and 6 months. Further measures ranged from demographic and clinical parameters to a measure of attitudes towards internet interventions (Attitudes towards Psychological Online Interventions Questionnaire). The recruitment source was only associated with very few of the examined demographic and clinical characteristics. Compared with participants recruited from clinical sources, participants recruited through insurance companies were more likely to be employed. Clinically recruited participants were as severely affected as those from other recruitment sources but more sceptical of internet interventions. The effectiveness of the intervention was not differentially associated with recruitment source (treatment by recruitment source interaction=0.28, p=0.84). Our results support the hypothesis that the intervention we studied is effective across different recruitment sources including clinical settings.

    Full Text Available Sheep and goat farming is a major source of income in the rural areas of Al-Wadiah in Najran region of Southern Saudi Arabia. The study aims to identify the factors and parameters that influence gender participation in sheep and goat farming. Data were collected by interviewing 167 high school students, including 70 male and 97 female students, in Al-Wadiah, by using the simple random sampling technique. Data were statistically analyzed to establish the relationship between gender and participation in sheep and goat farming. The study revealed significant differences between the two genders, for instance, male herders were more experienced, received more benefits, showed greater interest in discussions on topics related to sheep and goat farming, followed information from TV and radio, and received more services offered by veterinary clinics, which proved more beneficial for them. On the other hand, female herders received fewer services, and the veterinary clinics proved less beneficial for them. However, the correlation between the participation of both genders in sheep and goats management was non-significant toward the statement “feeling ashamed of participating in sheep and goat farming.” Generally, sheep and goat rearing proves more beneficial for male participants than female participants, owing to their greater experience and interest in livestock farming. Moreover, they receive more benefits from TV, radio and veterinary clinics to maintain better health of their livestock. Both male and female herders contribute equally to sheep and goat farming by limiting the time spent on their daily routine. This study would enable policymakers and planners to develop more strategies and extension education programs to overcome the identified barriers and improve the livelihood of herders through their enhanced participation in remote areas.

    The first Source Physics Experiment shot (SPE-1) was conducted in May 2011. The explosive source was a ~100-kilogram TNT-equivalent chemical set at a depth of 60 meters. It was recorded by an extensive set of instrumentation that includes sensors both at near-field (less than 100 meters) and far-field (more than 100 meters) distances. The near-field instruments consisted of three-component accelerometers deployed in boreholes around the shot and a set of singlecomponent vertical accelerometers on the surface. The far-field network comprised a variety of seismic and acoustic sensors, including short-period geophones, broadband seismometers, three-component accelerometers, and rotational seismometers at distances of 100 meters to 25 kilometers. This report coincides with the release of these data for analysts and organizations that are not participants in this program. This report describes the first Source Physics Experiment and the various types of near-field and far-field data that are available.

    Full Text Available The Code4Lib community has produced an increasingly impressive collection of open source software over the last decade, but much of this creative work remains out of reach for large portions of the library community. Do the relatively privileged institutions represented by a majority of Code4Lib participants have a professional responsibility to support the adoption of their innovations? Drawing from old and new software packaging and distribution approaches (from freeware to Docker, we propose extending the open source software values of collaboration and transparency to include the wide and affordable distribution of software. We believe this will not only simplify the process of sharing our applications within the library community, but also make it possible for less well-resourced institutions to actually use our software. We identify areas of need, present our experiences with the users of our own open source projects, discuss our attempts to go beyond open source, propose a preliminary set of technology availability performance indicators for evaluating software availability, and make an argument for the internal value of supporting and encouraging a vibrant library software ecosystem.

    Relationships of trust between research participants and researchers are often considered paramount to successful research; however, we know little about participants' perspectives. We examined whom research participants trusted when taking part in research. Using a qualitative approach, we interviewed 36 research participants, including eight Indigenous participants. Thematic analysis was used to analyze the data. This article focuses on findings related to non-Indigenous participants. In contrast to Indigenous participants, non-Indigenous participants placed their trust in research institutions because of their systems of research ethics, their reputation and prestige. Researchers working in non-Indigenous contexts need to be cognizant that the trust that participants place in them is closely connected with the trust that participants have in the institution.

    Earth System Science Education for the 21st Century (ESSE 21), sponsored by NASA through the Universities Space Research Association (USRA), is a collaborative undergraduate/graduate education program offering small grants to colleges and universities to engage a diverse interdisciplinary community of faculty and scientists in the development of courses, curricula and degree programs and sharing of learning resources focused on the fundamental understanding and application of Earth system principles for the classroom and laboratory. Through an expanded focus including partnerships with minority institutions, ESSE 21 is further developing broadly based courses, educational resources, electronic learning materials and degree programs that extend Earth system science concepts in both undergraduate and graduate classrooms and laboratories. These resources emphasizing the fundamentals of Earth system science advance the nation's broader agenda for improving science, technology, engineering and mathematics competency. The thrust to establish Earth system and global change science within the classrooms of colleges and universities is critical to laying and extending the foundation for knowledge-based decision making in the 21st century by both scientists and society in an effort to achieve sustainability. ESSE 21 released a Call for Participation (CFP) in the Fall of 2002 soliciting proposals from undergraduate institutions to create and adopt undergraduate and graduate level Earth system science content in courses, curricula and degree programs. In February 2003, twelve college and university teams were competitively selected through the CFP as the Year 1 and Year 2 Program participants. Eight of the participating teams are from minority institutions. The goal for all is to effect systemic change through developing Earth system science learning materials, courses, curricula, degree tracks or programs, and departments that are self-sustaining in the coming decades.

    2017-01-01

    Background The past twenty years have seen distinct shifts in the way the participation of children and adolescents in research is viewed. This has been emphasized by the growing pediatric research enterprise. Additional information on children’s and adolescents’ experiences during research participation is needed to better inform researchers on the ethical conduct of research with this vulnerable population. Aims The objective of this analysis was to examine ethical issues in research with children and adolescents from their perspective as participants, including: assent, parental consent, risk perception, impact of research participation, and incentives. Methods This systematic review was conducted per the Long et al. framework by means of an iterative searching process. Using the key words ‘research ethics’ and ‘child or pediatric or adolescent’, PubMed, CINAHL, and EBSCOhost databases were searched to identify articles. Limitations placed on the original searches were: English language, year of publication between 2003–2014, humans, abstract available, and age birth–18 years. Findings Twenty-three empiric studies were identified and formed the sample. Included studies represented a diverse range of areas of research, methods, settings, sample demographics, authors, and journals. Discussion Even young children demonstrated the ability to understand essential elements of research, although there is variability in children’s level of understanding. Trust was a significant contributing factor to children’s and adolescents’ participation in research, and also shaped their assessments of risk. Research participation was mainly beneficial for children and adolescents. Incentives were mainly viewed positively, although concerns of possible undue influence were expressed. Linking Evidence to Action This systematic review highlights the importance of including the perspectives of children and adolescents and provides researchers and nurse clinicians

    Lead is still seen as one of the most harmful environmental toxins for young children, with the predominant source being deteriorating lead-based paint. Those at continued risk include those living in homes built before 1978, renovators and remodelers, and especially those with limited access to proper healthcare and diets. Proper training on lead-safe work practices focused on preventing and reducing the spread of lead dust can help reduce lead exposure. Presented in this paper are experiences in delivering lead-safe work practices training in six Arkansas cities, and results from pre- and post- surveys delivered before and immediately after the training. Pre- and post-surveys assess strong and weak areas of training. Participants demonstrated positive shifts in attitude and behavior towards lead-safe work practices following training. However, our research found that more emphasis should be focused on clarifying current lead exposure sources and routes for children.

    Full Text Available The general objective of the study was to determine the factors that influenced youth participation in agricultural labour in Abia state, Nigeria. The specific objectives were to; identify the types and composition of farm labour engaged by the respondents in the study area, determine the factors that influence participation of the youths in agricultural labour; and make recommendations based on the findings. This study employed a multi-stage sampling technique in the selection of the respondents; where 4 local government areas (LGAs were selected from each of the agricultural zone, 10 communities randomly selected from each of these local government areas and finally, 10 youth farmers were chosen from the 10 communities. In all, a total number of 100 farmers were used for the study. The source of data was primary and so used questionnaire to solicit information from the respondents. Descriptive statistics and probit model were employed in the analysis of the data. Apart from bush clearing and mound making where males participated majorly, female’s percentage in the participation of all other farm operations outnumbered those of men. Estimates of the determinants of agricultural labour participation among youths in the study area showed that the coefficients of education of the respondents, income from nonagricultural sources, occupation of the parents, education of the father, farm size and the rate of mechanization influenced agricultural labour participation among the youths in Abia State, Nigeria. Apart from the coefficient of farm size that had a positive sign, the other variables had negative relationship. The study recommended that the cost of mechanization should be made affordable amongst other things to attract youths in agricultural participation.

    Abstract Background Ralstonia pickettii is a nosocomial infectious agent and a significant industrial contaminant. It has been found in many different environments including clinical situations, soil and industrial High Purity Water. This study compares the phenotypic and genotypic diversity of a selection of strains of Ralstonia collected from a variety of sources. Results Ralstonia isolates (fifty-nine) from clinical, industrial and environmental origins were compared genotypically using i) Species-specific-PCR, ii) PCR and sequencing of the 16S-23S rRNA Interspatial region (ISR) iii) the fliC gene genes, iv) RAPD and BOX-PCR and v) phenotypically using biochemical testing. The species specific-PCR identified fifteen out of fifty-nine designated R. pickettii isolates as actually being the closely related species R. insidiosa. PCR-ribotyping of the 16S-23S rRNA ISR indicated few major differences between the isolates. Analysis of all isolates demonstrated different banding patterns for both the RAPD and BOX primers however these were found not to vary significantly. Conclusions R. pickettii species isolated from wide geographic and environmental sources appear to be reasonably homogenous based on genotypic and phenotypic characteristics. R. insidiosa can at present only be distinguished from R. pickettii using species specific PCR. R. pickettii and R. insidiosa isolates do not differ significantly phenotypically or genotypically based on environmental or geographical origin.

    OBJECT There is currently no consensus on the safety of sports participation for patients with an intracranial arachnoid cyst (AC). The authors' goal was to define the risk of sports participation for children with this imaging finding. METHODS A survey was prospectively administered to 185 patients with ACs during a 46-month period at a single institution. Cyst size and location, treatment, sports participation, and any injuries were recorded. Eighty patients completed at least 1 subsequent survey following their initial entry into the registry, and these patients were included in a prospective registry with a mean prospective follow-up interval of 15.9 ± 8.8 months. RESULTS A total 112 patients with ACs participated in 261 sports for a cumulative duration of 4410 months or 1470 seasons. Of these, 94 patients participated in 190 contact sports for a cumulative duration of 2818 months or 939 seasons. There were no serious or catastrophic neurological injuries. Two patients presented with symptomatic subdural hygromas following minor sports injuries. In the prospective cohort, there were no neurological injuries CONCLUSIONS Permanent or catastrophic neurological injuries are very unusual in AC patients who participate in athletic activities. In most cases, sports participation by these patients is safe.

    The concept of participation has been extensively used in health and social care literature since the World Health Organization introduced its description in the International Classification of Functioning, Disability and Health (ICF) in 2001. More recently, the concept of social participation is frequently used in research articles and policy reports. However, in the ICF, no specific definition exists for social participation, and an explanation of differences between the concepts is not available. The central question in this discussion article is whether participation, as defined by the ICF, and social participation are distinct concepts. This article illustrates the concepts of participation and social participation, presents a critical discussion of their definitions, followed by implications for rehabilitation and possible future directions. A clear definition for participation or social participation does not yet exist. Definitions for social participation differ from each other and are not sufficiently distinct from the ICF definition of participation. Although the ICF is regarded an important conceptual framework, it is criticised for not being comprehensive. The relevance of societal involvement of clients is evident for rehabilitation, but the current ICF definition of participation does not sufficiently capture societal involvement. Changing the ICF's definition of participation towards social roles would overcome a number of its shortcomings. Societal involvement would then be understood in the light of social roles. Consequently, there would be no need to make a distinction between social participation and participation.

Consequently, this paper explores three questions: a) how do social workers manage to surveil the wellbeing of children, b) how do children relate to social...... for surveilling, controlling and caring for the wellbeing of placed children. Similarly, social workers are also obliged to include children as participants in their own case.

    The purpose of this research was to retrospectively examine whether demographic differences exist between those who participated in an employee wellness program and those who did not, and to identify the selection of employees' choice in weight management activities. A nonequivalent, 2-group retrospective design was used. This study involved employees at a large, not-for-profit integrated health system. Of the total organization employee pool (29,194), 19,771 (68%) employees volunteered to be weighed (mean body mass index [BMI]=28.9) as part of an employee wellness program. Weight management activities available included: (1) Self-directed 5% total body weight loss; (2) Healthy Solutions at home; (3) Weight Watchers group meetings; (4) Weight Watchers online; and (5) Employee Assistance Program (EAP)-directed healthy weight coaching. Measures were participation rate and available weight management activity participation rate among obese employees across demographic variables, including sex, age, race, job type, and job location. The analysis included chi-square tests for all categorical variables; odds ratios were calculated to examine factors predictive of participation. Of the total 19,771 employees weighed, 6375 (32%) employees were obese (defined as BMI ≥30); of those, 3094 (49%) participated in available weight management activities. Participation was higher among females, whites, those ages >50 years, and non-nursing staff. In conclusion, participation rate varied significantly based on demographic variables. Self-directed 5% weight loss was the most popular weight management activity selected. (Population Health Management 2016;19:132-135).

    This paper discusses the sources of radiation in the narrow perspective of radioactivity and the even narrow perspective of those sources that concern environmental management and restoration activities at DOE facilities, as well as a few related sources. Sources of irritation, Sources of inflammatory jingoism, and Sources of information. First, the sources of irritation fall into three categories: No reliable scientific ombudsman to speak without bias and prejudice for the public good, Technical jargon with unclear definitions exists within the radioactive nomenclature, and Scientific community keeps a low-profile with regard to public information. The next area of personal concern are the sources of inflammation. This include such things as: Plutonium being described as the most dangerous substance known to man, The amount of plutonium required to make a bomb, Talk of transuranic waste containing plutonium and its health affects, TMI-2 and Chernobyl being described as Siamese twins, Inadequate information on low-level disposal sites and current regulatory requirements under 10 CFR 61, Enhanced engineered waste disposal not being presented to the public accurately. Numerous sources of disinformation regarding low level radiation high-level radiation, Elusive nature of the scientific community, The Federal and State Health Agencies resources to address comparative risk, and Regulatory agencies speaking out without the support of the scientific community

  1. Rural Household Preferences for Active Participation in "Payment for Ecosystem Service" Programs: A Case in the Miyun Reservoir Catchment, China.

    Directory of Open Access Journals (Sweden)

    Hao Li

    Full Text Available Many payment for ecosystem services (PES programs, such as the Slope Land Conversion Program (SLCP, are passive and require full participation by impacted households. In contrast, this study considers the alternative of "active and incomplete" participation in PES programs, in which participants are not obliged to contract their own land, and have the right to select into the program or not. This type of program has been popular over the last decade in China; however, there have been few studies on the characteristics of willingness to participate and implementation. As such, this paper uses the Choice Experiment (CE method to explore ways for inducing effective program participation, by analyzing the effects of different regime attributes. The case study used to analyze participation utility was the Jing-Ji Afforestation Program for Ecological and Water Protection (JAPEWP, a typical active-participation forestry PES program, and a key source of water near Beijing in the Miyun Reservoir Catchment (MRC. Analyzing rural household survey data indicated that the program faces a variety of challenges, including long-term maintenance, implementation performance, cost-effectiveness, and monitoring approaches. There are also challenges with one-size-fits-all payment strategies, due to ineffective program participation or imperfect implementation regimes. In response, this study proposes several policies, including providing secure and complete land tenure to the participants, creating more local off-farm employment opportunities, designing performance-based monitoring systems that are integrated with financial incentives, applying differentiated payment strategies, providing capacity building to support forestation activities, and establishing a comprehensive implementation regime that would address these challenges. These policy conclusions provide valuable lessons for other active-participation PES programs as well.

    The most productive methods of recruitment for a videogame for health (G4H) trial are not known. Success or failure of recruitment methods has been reported for a variety of clinical trials, but few specifically for G4H trials. This study's goal was to recruit 444 overweight or obese (body mass index percentile between the 84.5th-99.4th percentiles) children between the ages of 10-12 years. The article reports the results of different methods of participant recruitment. Participants had to agree to three fasting blood samples (baseline, immediately after, and 2 months later); be willing to wear an accelerometer for 7 days at each assessment; read and speak English fluently (because the games were in English); have no history of any condition that would affect what he/she could eat or how much physical activity he/she could get; and have an eligible home computer purchased in the last 5 years with high-speed internet. Hardware criteria reflected the types of computers upon which Diab-Nano could be effectively played. Recruitment was conducted over a 35-month period and included electronic media, print advertising, community recruitment, and an internal volunteer list. Respondents were guided to a web-based screening questionnaire that asked for source of hearing about the study. Although diverse recruitment methods were used, slow recruitment resulted in obtaining only 45% of the recruitment goal (n = 199). Electronic media (e.g., radio, television, and internet), which reached millions of targeted parents, resulted in only 76 respondents, of whom 13 became participants; print media (e.g., magazine, newsletter/newspaper, and mail), which also reached large numbers of parents, resulted in 192 respondents, of whom 19 became participants; community recruitment (e.g., school, friend or family, doctors office, flyer, work, community program) resulted in 162 respondents, of whom 38 became participants; and the internal volunteer list resulted in 413 respondents, of

    This paper presents a comprehensive assessment of historical (1990-2010) global anthropogenic particulate matter (PM) emissions including the consistent and harmonized calculation of mass-based size distribution (PM1, PM2. 5, PM10), as well as primary carbonaceous aerosols including black carbon (BC) and organic carbon (OC). The estimates were developed with the integrated assessment model GAINS, where source- and region-specific technology characteristics are explicitly included. This assessment includes a number of previously unaccounted or often misallocated emission sources, i.e. kerosene lamps, gas flaring, diesel generators, refuse burning; some of them were reported in the past for selected regions or in the context of a particular pollutant or sector but not included as part of a total estimate. Spatially, emissions were calculated for 172 source regions (as well as international shipping), presented for 25 global regions, and allocated to 0.5° × 0.5° longitude-latitude grids. No independent estimates of emissions from forest fires and savannah burning are provided and neither windblown dust nor unpaved roads emissions are included. We estimate that global emissions of PM have not changed significantly between 1990 and 2010, showing a strong decoupling from the global increase in energy consumption and, consequently, CO2 emissions, but there are significantly different regional trends, with a particularly strong increase in East Asia and Africa and a strong decline in Europe, North America, and the Pacific region. This in turn resulted in important changes in the spatial pattern of PM burden, e.g. European, North American, and Pacific contributions to global emissions dropped from nearly 30 % in 1990 to well below 15 % in 2010, while Asia's contribution grew from just over 50 % to nearly two-thirds of the global total in 2010. For all PM species considered, Asian sources represented over 60 % of the global anthropogenic total, and residential combustion

    Various examples are provided for land streamer seismic surveying using multiple sources. In one example, among others, a method includes disposing a land streamer in-line with first and second shot sources. The first shot source is at a first source location adjacent to a proximal end of the land streamer and the second shot source is at a second source location separated by a fixed length corresponding to a length of the land streamer. Shot gathers can be obtained when the shot sources are fired. In another example, a system includes a land streamer including a plurality of receivers, a first shot source located adjacent to the proximal end of the land streamer, and a second shot source located in-line with the land streamer and the first shot source. The second shot source is separated from the first shot source by a fixed overall length corresponding to the land streamer.

    Five isolates of coagulase-negative staphylococci were obtained from human urine, the gastrointestinal tract of squirrel monkeys, pig skin and from the environment. All key biochemical characteristics of the tested strains corresponded with the description of Staphylococcus xylosus species. However, partial 16S rRNA gene sequences obtained from analysed strains corresponded with those of Staphylococcus nepalensis reference strains, except for two strains which differed in one residue. Ribotyping with EcoRI and HindIII restriction enzymes, whole cell protein profile analysis performed by SDS-PAGE and SmaI macrorestriction analysis were used for more precise characterization and identification of the analysed strains. Obtained results showed that EcoRI and HindIII ribotyping and whole cell protein fingerprinting are suitable and reliable methods for the differentiation of S. nepalensis strains from the other novobiocin resistant staphylococci, whereas macrorestriction analysis was found to be a good tool for strain typing. The isolation of S. nepalensis is sporadic, and according to our best knowledge this study is the first report of the occurrence of this species in human clinical material as well as in other sources.

    Full Text Available Despite forty years of research, community sector service providers still find operationalising participation in their practice confusing and difficult.  This paper presents the results of a preliminary study that begins to question why this is so and what can be done about it?  The study examines the meaning and importance of participation determined by a review of the academic literature, by soliciting feedback from a range of stakeholders in community sector organisations, including service users with complex barriers to participation, staff, and board members.  The participants’ perspectives, views and experience of participation were obtained through the use of semi-structured interviews.  The data generated a number of telling examples of the impact organisational culture has on service delivery and how the values of the leadership shape the organization, as well as illustrations of the principles that underpin participation expressed from the standpoints of the three participant groups.  Study findings underscore the critical importance for service providers to consider their culture and its influences.   Keywords: organisational culture, vulnerable clients, client participation

  8. Neural system for updating object working memory from different sources: sensory stimuli or long-term memory.

    Working memory (WM) is the active maintenance of currently relevant information so that it is available for use. A crucial component of WM is the ability to update the contents when new information becomes more relevant than previously maintained information. New information can come from different sources, including from sensory stimuli (SS) or from long-term memory (LTM). Updating WM may involve a single neural system regardless of source, distinct systems for each source, or a common network with additional regions involved specifically in sensory or LTM processes. The current series of experiments indicates that a single fronto-parietal network (including supplementary motor area, parietal, left inferior frontal junction, middle frontal gyrus) is active in updating WM regardless of the source of information. Bilateral cuneus was more active during updating WM from LTM than updating from SS, but the activity in this region was attributable to recalling information from LTM regardless of whether that information was to be entered into WM for future use or not. No regions were found to be more active during updating from SS than updating from LTM. Functional connectivity analysis revealed that different regions within this common update network were differentially more correlated with visual processing regions when participants updated from SS, and more correlated with LTM processing regions when participants updated from the contents of LTM. These results suggest that a single neural mechanism is responsible for controlling the contents of WM regardless of whether that information originates from a sensory stimulus or from LTM. This network of regions involved in updating WM interacts with the rest of the brain differently depending on the source of newly relevant information.

    Facebook continues to grow in popularity among adolescents as well as adolescent researchers. Guidance on conducting research using Facebook with appropriate attention to privacy and ethics is scarce. To inform such research efforts, the purpose of this study was to determine older adolescents' responses after learning that they were participants in a research study that involved identification of participants using Facebook. Public Facebook profiles of older adolescents aged 18-19 years from a large state university were examined. Profile owners were then interviewed. During the interview, participants were informed that they were identified by examining publicly available Facebook profiles. Participants were asked to discuss their views on this research method. A total of 132 participants completed the interview (70% response rate); the average age was 18.4 years (SD = .5); and our sample included 64 male participants (48.5%). Participant responses included endorsement (19.7%), fine (36.4%), neutral (28.8%), uneasy (9.1%), and concerned (6.1%). Among participants who were uneasy or concerned, the majority voiced confusion regarding their current profile security settings (p = .00). The majority of adolescent participants viewed the use of Facebook for research positively. These findings are consistent with the approach taken by many U.S. courts. Researchers may consider these findings when developing research protocols involving Facebook. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    The aim of this qualitative study was to examine young female sport participants' experiences and thoughts in terms of sport, their bodies, and social appearance norms. Six focus groups with female sport participants (N=25) from Sweden were conducted. Participants raised many positive experiences in relation to their sport participation, but they also witnessed a conflict in the intersection between the culture within their sport (emphasizing physical performance) and the culture outside their sport (emphasizing physical appearance). Through thematic analysis, four themes illustrating the balancing act between these two cultures were formed: (a) the performing body versus the objectified body, (b) food as fuel versus source of shame, (c) appreciation of body type diversity versus appearance prejudice, and (d) empowerment and agency versus disempowerment and restraints. The findings of this study indicate that young women who engage in sport have to face complex, ambiguous, and restricting norms and notions. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2008-08-01

    Recruiting minority populations living with HIV to many types of clinic-based HIV research is a concern. This study examined an expanded range of predictors of HIV research participation (clinic contact, clinical, and personal characteristics) to investigate observed ethnocultural differences in HIV research participation. Research participation was defined as participation in any of diagnostic, pathogenesis, drug trial or survey research. Logistic regression modeling was used to predict research participation of 657 eligible patients (93% of the patient population) who began care between January 1997 and the end of September 2003 at a regional outpatient HIV care program in Calgary, Canada. Approximately one third (32%) were non-white, including 18% Aboriginal, 9% black, 4% Asian, and 1% Hispanic individuals. Twenty-nine percent (187/657) of the patients participated in at least one study of any kind. Multivariate analysis indicated that the strongest predictors of any research participation (including diagnostic, pathogenesis, drug trial, or survey studies) are clinical (including nadir CD4 count [odds ratio {OR} = 0.132, p percentage of appointments kept [OR = 1.022, p service use shown by these groups that may influence research participation. To attract under researched populations, attention should shift from the "who" of research participation to the "how" of clinical interactions.

    The aim of the present study was to investigate the prevalence of burnout and occupational participation limitation among dental students in a dental school in Turkey. Four hundred fifty-eight dental students (females=153; males=305) were included in the study. The age range varied from 17-to-38 years. Maslach Burnout Inventory-Student Version (MBI-SV) and Canadian Occupational Performance Measure (COPM) were used to gather data. Descriptive analyses, t-test, and Kruskall-Wallis test for independent groups were used for data analyses. The results indicated that 26% of all the students have burnout in terms of emotional exhaustion (25%), cynicism (18%), and academic efficacy (14%). The results showed that burnout is statistically significant in relation to demographics (pstudents showed considerably decreased occupational performance and satisfaction scores, which suggested occupational participation limitations. Occupational performance and satisfaction scores were inversely correlated with emotional exhaustion and cynicism, while directly correlated with reduced academic efficacy (pburnout and occupational participation limitation can be seen among dental students. Students with burnout may also have occupational participation limitation. Enriching dental education programs with different psychological strategies may be useful for education of healthy dentists and improve the quality of oral and dental health services.

    Thousands of boys and girls younger than 19 years participate in boxing in North America. Although boxing provides benefits for participants, including exercise, self-discipline, and self-confidence, the sport of boxing encourages and rewards deliberate blows to the head and face. Participants in boxing are at risk of head, face, and neck injuries, including chronic and even fatal neurologic injuries. Concussions are one of the most common injuries that occur with boxing. Because of the risk of head and facial injuries, the American Academy of Pediatrics and the Canadian Paediatric Society oppose boxing as a sport for children and adolescents. These organizations recommend that physicians vigorously oppose boxing in youth and encourage patients to participate in alternative sports in which intentional head blows are not central to the sport.

    Research on nonformal education often focuses on participation within employment. Participation of workers decreases with age; however, recent studies show an increase in participation in nonformal education of older workers. It remains, however, unclear if this trend spills over to retirement. In the context of social change processes, trends in nonformal educational participation are analyzed. The study addresses employment and retirement as opportunity structures and investigates their impact on educational participation in the second half of life. Predictors of educational participation are modeled in logistic regression, including interaction effects. Analyses are based on cross-sectional data of the German Ageing Survey and covers 20,129 respondents aged 40-85 years (T 1 : 1996 n = 4838; T 2 : 2002 n = 3084; T 3 : 2008 n = 6205; T 4 : 2014 n = 6002). Educational level, age, gender, employment status, region, social integration, and subjective health predict participation in nonformal education for people aged 40 to 85 years. Employment as an opportunity structure has a constant impact on participation, whereas retirees' participation increases over the course of time. The increase of retirees' participation in nonformal education is discussed in the context of social change processes and connected to theoretical und empirical research gaps with regard to educational participation in the second half of life.

    2015-12-01

    The need for broader understanding and involvement in science coupled with social technology advances enabling crowdsourcing and citizen science have created greater opportunities for public participation in the gathering, interpretation, and use of geospatial information. The U.S. Geological Survey (USGS) is developing guidance for USGS scientists, partners, and interested members of the public on when and how public participation can most effectively be used in the conduct of scientific activities. Public participation can provide important perspectives and knowledge that cannot be obtained through traditional scientific methods alone. Citizen engagement can also provide increased efficiencies to USGS science and additional benefits to society including enhanced understanding, appreciation, and interest in geospatial information and its use in decision making.The USGS guidance addresses several fundamental issues by:1. Developing an operational definition of citizen or participatory science.2. Identifying the circumstances under which citizen science is appropriate for use and when its use is not recommended. 3. Describing structured processes for effective use of citizen science. 4. Defining the successful application of citizen science and identifying useful success metrics.The guidance is coordinated by the USGS Science and Decisions Center and developed by a multidisciplinary team of USGS scientists and managers. External perspectives will also be incorporated, as appropriate to align with other efforts such as the White House Office of Science and Technology Policy (OSTP) Citizen Science and Crowdsourcing Toolkit for the Federal government. The guidance will include the development of an economic framework to assess the benefits and costs of geospatial information developed through participatory processes. This economic framework considers tradeoffs between obtaining additional perspectives through enhanced participation with costs associated from obtaining

    Boyce, W F

    2001-05-01

    A structural perspective was used in studying community participation of disadvantaged groups (poor women, street youth, and disabled persons) in health promotion projects. Five community projects in the Canadian Health Promotion Contribution Program were examined in a comparative case study utilizing in-depth interviews, documents, and secondary sources. Analysis revealed relatively low numbers and restricted range of participants, difficulties in recruiting and maintaining participants, declining rates of active participation over time, and limited target group influence and power. This paper reports on the relationship between various dimensions of structure (social-cultural, organizational, political-legal-economic) and the community participation process. Participation was influenced by structural factors such as bureaucratic rules and regulators, perceived minority group rights and relations, agency reputations and responsibilities, available resources, and organizational roles. Control of projects by target group members, rather than by service agencies, was an important overall organizational structural factor which allowed community members to achieve influence in projects. The study concludes that a conceptual model based on structural factors is useful in explaining how key factors from federal and local levels can restrict or facilitate the community participation process.

    2012-01-01

    Although people are generally interested in how the brain functions, neuroscience education for the public is hampered by a lack of low cost and engaging teaching materials. To address this, we developed an open-source tool, the SpikerBox, which is appropriate for use in middle/high school educational programs and by amateurs. This device can be used in easy experiments in which students insert sewing pins into the leg of a cockroach, or other invertebrate, to amplify and listen to the electrical activity of neurons. With the cockroach leg preparation, students can hear and see (using a smartphone oscilloscope app we have developed) the dramatic changes in activity caused by touching the mechanosensitive barbs. Students can also experiment with other manipulations such as temperature, drugs, and microstimulation that affect the neural activity. We include teaching guides and other resources in the supplemental materials. These hands-on lessons with the SpikerBox have proven to be effective in teaching basic neuroscience. PMID:22470415

    Purpose Facebook continues to grow in popularity among adolescents as well as adolescent researchers. Guidance on conducting this research with appropriate attention to privacy and ethics is scarce. To inform such research efforts, the purpose of this study was to determine older adolescents’ responses after learning that they were participants in a research study that involved identification of participants using Facebook. Methods Public Facebook profiles of older adolescents age 18 to 19 years from a large state university were examined. Profile owners were then interviewed. During the interview participants were informed that they were identified by examining publicly available Facebook profiles. Participants were asked to discuss their views on this research method. Results A total of 132 participants completed the interview (70% response rate), the average age was 18.4 years (SD=0.5) and our sample included 64 males (48.5%). Participant responses included: endorsement (19.7%), fine (36.4%), neutral (28.8%), uneasy (9.1%) and concerned (6.1%). Among participants who were uneasy or concerned, the majority voiced confusion regarding their current profile security settings (p=0.00). Conclusion The majority of adolescent participants viewed the use of Facebook for research positively. These findings are consistent with the approach taken by many US courts. Researchers may consider these findings when developing research protocols involving Facebook. PMID:23084164

    1994-11-01

    In a series of experiments, we investigated the effect of race of source on persuasive communications in the Elaboration Likelihood Model (R.E. Petty & J.T. Cacioppo, 1981, 1986). In Experiment 1, we found no evidence that White participants responded to a Black source as a simple negative cue. Experiment 2 suggested the possibility that exposure to a Black source led to low-involvement message processing. In Experiments 3 and 4, a distraction paradigm was used to test this possibility, and it was found that participants under low involvement were highly motivated to process a message presented by a Black source. In Experiment 5, we found that attitudes toward the source's ethnic group, rather than violations of expectancies, accounted for this processing effect. Taken together, the results of these experiments are consistent with S.L. Gaertner and J.F. Dovidio's (1986) theory of aversive racism, which suggests that Whites, because of a combination of egalitarian values and underlying negative racial attitudes, are very concerned about not appearing unfavorable toward Blacks, leading them to be highly motivated to process messages presented by a source from this group.

    Japan Atomic energy Research Institute (JAERI) is the only facility to supply and distribute radioisotopes (RI) in Japan. The γ-ray sources for medical use are 192 Ir and 169 Yb for non-destructive examination and 192 Ir, 198 Au and 153 Gd for clinical use. All of these demands in Japan are supplied with domestic products at present. Meanwhile, γ-ray sources imported are 60 Co sources for medical and industrial uses including sterilization of medical instruments, 137 Cs for irradiation to blood and 241 Am for industrial measurements. The major overseas suppliers are Nordion International Inc. and Amersham International plc. RI products on the market are divided into two groups; one is the primary products which are supplied in liquid or solid after chemical or physical treatments of radioactive materials obtained from reactor and the other is the secondary product which is a final product after various processing. Generally these secondary products are used in practice. In Japan, both of the domestic and imported products are supplied to the users via JRIA (Japan Radioisotope Association). The association participates in the sales and the distributions of the secondary products and also in the processings of the primary ones to their sealed sources. Furthermore, stable supplying systems for these products are almost established according to the half life of each nuclide only if there is no accident in the reactor. (M.N.)

    Full Text Available Abstract Background ParticipACTION was a pervasive communication campaign that promoted physical activity in the Canadian population for three decades. According to McGuire's hierarchy-of-effects model (HOEM, this campaign should influence physical activity through intermediate mediators such as beliefs and intention. Also, when such media campaigns occur, knowledge gaps often develop within the population about the messages being conveyed. The purposes of this study were to (a determine the current awareness of ParticipACTION campaigns among Canadians; (b confirm if awareness of the ParticipACTION initiative varied as a function of levels of education and household income; and, (c to examine whether awareness of ParticipACTION was associated with physical activity related beliefs, intentions, and leisure-time physical activity (LTPA as suggested by the HOEM. Specifically, we tested a model including awareness of ParticipACTION (unprompted, prompted, outcome expectations, self-efficacy, intention, and physical activity status. Methods A population-based survey was conducted on 4,650 Canadians over a period of 6 months from August, 2007 to February, 2008 (response rate = 49%. The survey consisted of a set of additional questions on the 2007 Physical Activity Monitor (PAM. Our module on the PAM included questions related to awareness and knowledge of ParticipACTION.

    We examined whether people can detect analogical resemblance to an earlier experimental episode without being able to recall the experimental source of the analogical resemblance. We used four-word analogies (e.g., robin-nest/beaver-dam), in a variation of the recognition-without-cued-recall method (Cleary, 2004). Participants studied word pairs (e.g., robin-nest) and were shown new word pairs at test, half of which analogically related to studied word pairs (e.g., beaver-dam) and half of which did not. For each test pair, participants first attempted to recall an analogically similar pair from the study list. Then, regardless of whether successful recall occurred, participants were prompted to rate the familiarity of the test pair, which was said to indicate the likelihood that a pair that was analogically similar to the test pair had been studied. Across three experiments, participants demonstrated an ability to detect analogical resemblance without recalling the source analogy. Findings are discussed in terms of their potential relevance to the study of analogical reasoning and insight, as well as to the study of familiarity and recognition memory.

    Exposure estimates that do not account for time in-transit may underestimate exposure to traffic-related air pollution, but exact contributions have not been studied directly. We conducted a 2-week monitoring, including novel in-vehicle sampling, in a subset of the Multi-Ethnic Study of Atherosclerosis and Air Pollution cohort in two cities. Participants spent the majority of their time indoors and only 4.4% of their time (63 min/day) in-vehicle, on average. The mean ambient-source NO 2 concentration was 5.1 ppb indoors and 32.3 ppb in-vehicle during drives. On average, indoor exposure contributed 69% and in-vehicle exposure contributed 24% of participants' ambient-source NO 2 exposure. For participants in the highest quartile of time in-vehicle (≥1.3 h/day), indoor and in-vehicle contributions were 60 and 31%, respectively. Incorporating infiltrated indoor and measured in-vehicle NO 2 produced exposure estimates 5.6 ppb lower, on average, than using only outdoor concentrations. The indoor microenvironment accounted for the largest proportion of ambient-source exposure in this older population, despite higher concentrations of NO 2 outdoors and in vehicles than indoors. In-vehicle exposure was more influential among participants who drove the most and for participants residing in areas with lower outdoor air pollution. Failure to characterize exposures in these microenvironments may contribute to exposure misclassification in epidemiologic studies.

    Memory complaint is common in the elderly. Recently, it was shown that self-report memory complaint was predictive of cognitive decline. This study aimed to investigate the predictive value of the source of memory complaints on the risk of cognitive impairment and cognitive decline in a community-based cohort. Data on memory complaints and cognitive function were collected among 1840 Chinese participants (aged ≥55 years old) in an urban community at baseline interview and 5-year follow-up. Incident cognitive impairment was identified based on education-adjusted Mini-Mental State Examination score. Logistic regression model was used to estimate the association between the source of memory complaints and risk of cognitive impairment conversion and cognitive decline, after adjusting for covariates. A total of 1840 participants were included into this study including 1713 normal participants and 127 cognitive impairment participants in 2009. Among 1713 normal participants in 2009, 130 participants were converted to cognitive impairment after 5 years of follow-up. In 2014, 606 participants were identified as cognitive decline. Both self- and informant-reported memory complaints were associated with an increased risk of cognitive impairment (odds ratio [OR] = 1.60, 95% confidence interval [CI]: 1.04-2.48) and cognitive decline (OR = 1.30, 95% CI: 1.01-1.68). Furthermore, this association was more significant in males (OR = 2.10, 95% CI: 1.04-4.24 for cognitive impairment and OR = 1.87, 95% CI: 1.20-2.99 for cognitive decline) and in higher education level (OR = 1.79, 95% CI: 1.02-3.15 for cognitive impairment and OR = 1.40, 95% CI: 1.02-1.91 for cognitive decline). Both self- and informant-reported memory complaints were associated with an increased risk of cognitive impairment conversion and cognitive decline, especially in persons with male gender and high educational background.

    One of the most widely used approaches in electroencephalography/magnetoencephalography (MEG) source imaging is application of an inverse technique (such as dipole modelling or sLORETA) on the component extracted by independent component analysis (ICA) (sensor-space ICA + inverse technique). The advantage of this approach over an inverse technique alone is that it can identify and localize multiple concurrent sources. Among inverse techniques, the minimum-variance beamformers offer a high spatial resolution. However, in order to have both high spatial resolution of beamformer and be able to take on multiple concurrent sources, sensor-space ICA + beamformer is not an ideal combination. We propose source-space ICA for MEG as a powerful alternative approach which can provide the high spatial resolution of the beamformer and handle multiple concurrent sources. The concept of source-space ICA for MEG is to apply the beamformer first and then singular value decomposition + ICA. In this paper we have compared source-space ICA with sensor-space ICA both in simulation and real MEG. The simulations included two challenging scenarios of correlated/concurrent cluster sources. Source-space ICA provided superior performance in spatial reconstruction of source maps, even though both techniques performed equally from a temporal perspective. Real MEG from two healthy subjects with visual stimuli were also used to compare performance of sensor-space ICA and source-space ICA. We have also proposed a new variant of minimum-variance beamformer called weight-normalized linearly-constrained minimum-variance with orthonormal lead-field. As sensor-space ICA-based source reconstruction is popular in EEG and MEG imaging, and given that source-space ICA has superior spatial performance, it is expected that source-space ICA will supersede its predecessor in many applications.

    Full Text Available There is concern that untreated individuals in mass drug administration (MDA programs for neglected tropical diseases can reduce the impact of elimination efforts by maintaining a source of transmission and re-infection.Treatment receipt was recorded against the community census during three MDAs with azithromycin for trachoma in The Gambia, a hypo-endemic setting. Predictors of non-participation were investigated in 1-9 year olds using random effects logistic regression of cross-sectional data for each MDA. Two types of non-participators were identified: present during MDA but not treated (PNT and eligible for treatment but absent during MDA (EBA. PNT and EBA children were compared to treated children separately. Multivariable models were developed using baseline data and validated using year one and two data, with a priori adjustment for previous treatment status. Analyses included approximately 10000 children at baseline and 5000 children subsequently. There was strong evidence of spatial heterogeneity, and persistent non-participation within households and individuals. By year two, non-participation increased significantly to 10.4% overall from 6.2% at baseline, with more, smaller geographical clusters of non-participating households. Multivariable models suggested household level predictors of non-participation (increased time to water and household head non-participation for both PNT and EBA; increased household size for PNT status only; non-inclusion in a previous trachoma examination survey and younger age for EBA only. Enhanced coverage efforts did not decrease non-participation. Few infected children were detected at year three and only one infected child was EBA previously. Infected children were in communities close to untreated endemic areas with higher rates of EBA non-participation during MDA.In hypo-endemic settings, with good coverage and no association between non-participation and infection, efforts to improve participation

    Educating and training healthcare professionals is known to improve the quality of transitional care for older adults. Arranging interprofessional meetings for healthcare professionals might be useful to improve patient participation skills in transitional care. To describe the learning activities used in The Meeting Point programme, focusing on patient participation in transitional care, and assess whether they increase healthcare professionals' awareness of and competencies relating to patient participation in the transitional care of older patients. Data were collected as part of an educational intervention programme, The Meeting Point, including three seminars on 'Patient participation in the transitional care of older patients' and four follow-up meetings. Participants were nurses, care assistants, doctors, physiotherapists, patient coordinators and administrative personnel from hospital, nursing homes and home-based care services. The Meeting Point was organised around four pillars: introduction, teaching session, group work activity and plenary discussion. Qualitative data included log reports, summaries of meetings, notes from group work activities, and reports from participants and from follow-up meetings. Feedback from participants shows that they were satisfied with meeting healthcare professionals from other units of care. A film scenario was perceived relevant for group work activity and useful in focusing participants' attention to patient participation. Follow-up meetings show that some nursing home wards, the emergency department and one medical ward at the hospital continued with ongoing work to improve quality of care. Efforts included implementation of an observational waiting room with comfortable chairs, planning for discharge in hospital admission, a daily patient flow registration system and motivational interviewing during admission to nursing home. The description of the learning activities used at The Meeting Point seminars shows that they

      Information regarding the relative risks of developing knee osteoarthritis (OA) as a result of sport participation is critical for shaping public health messages and for informing knee-OA prevention strategies. The purpose of this systematic review was to investigate the association between participation in specific sports and knee OA.   We completed a systematic literature search in September 2012 using 6 bibliographic databases (PubMed; Ovid MEDLINE; Journals@Ovid; American College of Physicians Journal Club; Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Review, Database of Abstracts of Reviews of Effects; and Ovid HealthStar), manual searches (4 journals), and reference lists (56 articles).   Studies were included if they met the following 4 criteria: (1) an aim was to investigate an association between sport participation and knee OA; (2) the outcome measure was radiographic knee OA, clinical knee OA, total knee replacement, self-reported diagnosis of knee OA, or placement on a waiting list for a total knee replacement; (3) the study design was case control or cohort; and (4) the study was written in English. Articles were excluded if the study population had an underlying condition other than knee OA.   One investigator extracted data (eg, group descriptions, knee OA prevalence, source of nonexposed controls).   The overall knee-OA prevalence in sport participants (n = 3759) was 7.7%, compared with 7.3% among nonexposed controls (referent group n = 4730, odds ratio [OR] = 1.1). Specific sports with a significantly higher prevalence of knee OA were soccer (OR = 3.5), elite-level long-distance running (OR = 3.3), competitive weight lifting (OR = 6.9), and wrestling (OR = 3.8). Elite-sport (soccer or orienteering) and nonelite-sport (soccer or American football) participants without a history of knee injury had a greater prevalence of knee OA than nonexposed participants.   Participants in soccer (elite and nonelite

    The attention-elaboration hypothesis of memory for schematically unexpected information predicts better source memory for unexpected than expected sources. In three source-monitoring experiments, the authors tested the occurrence of an inconsistency effect in source memory. Participants were presented with items that were schematically either very expected or very unexpected for their source. Multinomial processing tree models were used to separate source memory, item memory, and guessing bias. Results show an inconsistency effect in source memory accompanied by a compensatory schema-consistent guessing bias when expectancy strength is high, that is, when items are very expected or very unexpected for their source.

    Members of the public and patients repeatedly indicate their willingness to take part in research, but current United Kingdom research governance involves complex rules about gaining consent. Research participation registers that seek consent from participants to be approached about future studies have several potential benefits, including: increased research participation across clinical and healthy populations; simplified recruitment to health care research; support for people's autonomy in decision making; and improved efficiency and generalizability of research. These potential benefits have to be balanced against ethical and governance considerations. With appropriate processes in place, seeking prospective consent from patients and members of the public to be approached about future studies could potentially increase public participation in health research without compromising informed consent and other ethical principles. © The Author(s) 2016.

    Full Text Available The present paper is part of the research of the PhD thesis made by the author, having the title: Community Participation in Oradea, registered at the University of Oradea - Faculty of Social and Human Sciences. The general objectives of the paper are the explanation of different types of citizens involvement in the life of their community, the investigation of the existing relationships between different forms of participation, the interpretation of the effects different forms of participation have on the studied communities and the identification of relevant mechanism for the stimulation social involvement. The citizens' political and civil participation, social responsibility, community spirit, civic activism together with other concepts from the civil society's rhetoric entered the agenda of public debates together with the intensifying efforts for adhering to the European Community, being the subject of numerous studies conducted in this field. The need for a strong civic society, with interested and involved citizens in the life of the community which they belong to, for social and economical development belong to the same discourse of the strong democratic society, being challenged in the literature, starting with Tocqueville, Almond and Verba, to Putnam and many others. In parallel to the civil society's rhetoric and the analysis coming from this direction, are the studies and theories of community development, which on one side are based on development policies, regulations, institutional framework of development, but contain also aspects of citizens' involvement in evaluating the community problems, the decision making processes and in the actual implementation of solutions. Moreover the aspects of network belonging and social trust which are reflected in the concept of social capital are sources both for participation as well for economic and social development. The present paper reflects the analysis of the determinant factors which

    Objective assessment of surgical skills is resource intensive and requires valuable time of expert surgeons. The goal of this study was to assess the ability of a large group of laypersons using a crowd-sourcing tool to grade a surgical procedure (cricothyrotomy) performed on a simulator. The grading included an assessment of the entire procedure by completing an objective assessment of technical skills survey. Two groups of graders were recruited as follows: (1) Amazon Mechanical Turk users and (2) three expert surgeons from University of Washington Department of Otolaryngology. Graders were presented with a video of participants performing the procedure on the simulator and were asked to grade the video using the objective assessment of technical skills questions. Mechanical Turk users were paid $0.50 for each completed survey. It took 10 h to obtain all responses from 30 Mechanical Turk users for 26 training participants (26 videos/tasks), whereas it took 60 d for three expert surgeons to complete the same 26 tasks. The assessment of surgical performance by a group (n = 30) of laypersons matched the assessment by a group (n = 3) of expert surgeons with a good level of agreement determined by Cronbach alpha coefficient = 0.83. We found crowd sourcing was an efficient, accurate, and inexpensive method for skills assessment with a good level of agreement to experts' grading. Copyright © 2015 Elsevier Inc.

    Full Text Available Eyewitness memories are malleable and can be influenced by many factors. This study focuses on how construal of the self can influence the memory and create the post-event misinformation effect. It is hypothesised that individuals with interdependent self-construal are more influenced by an authoritative source than individuals with independent self-construal. After watching a short clip showing a theft, participants were presented with a co-witness testimony including some misinformation, which came either from a police officer off-duty or an anonymous passer-by. Participants, aged 18-35, were recruited in Belgium, Germany, Norway, Slovakia, Switzerland and the UK. They were evaluated regarding their independence/interdependence with the Self-Construal Scale.

  12. State-Level Renewable Energy Policy Implementation: How and Why Do Stakeholders Participate?

    2018-02-01

    Full Text Available For most of the twentieth century, large-scale, utility-owned power plants dominated electricity generation in the United States. Today, however, a growing share of electricity comes from renewable energy sources such as solar and wind energy, which are often small-scale and distributed. In the absence of significant national policies, the Renewable Portfolio Standard has emerged as the key state-level policy governing the deployment and use of renewable energy sources. While renewable energy offers new possibilities for clean energy generation, it also poses new regulatory and governance challenges as a wide range of stakeholders, such as the utilities, regulatory agencies, environmental and consumer advocacy groups, electricity generators, and private citizens, increasingly seek to influence how Renewable Portfolio Standards are implemented. In this study, we ask how and why do stakeholders participate in decision-making about how these policies are implemented? Given the unique context of renewable energy policy, the long-term and iterative nature of renewable energy policy implementation, and the wide range of actors involved, we look at the suite of participatory opportunities available to stakeholders. We interview stakeholders in two states—Colorado and Nevada—to identify the mechanisms through which stakeholders participate and the incentives (or disincentives that influence their willingness to do so. We find that while decision makers in both the states use a variety of mechanisms to engage stakeholders in decision-making, meaningful participation may be limited to stakeholder groups that are knowledgeable about the issues, have the resources to engage in long-term and sustained participation, and have long-standing relationships with decision makers and other stakeholders. Although many stakeholders participate in multiple types of processes to achieve a broader range of benefits, they often perceive their participation as

    Concepts such as health-related quality of life, disability and participation may differ across cultures. Consequently, when assessing such a concept using a measure developed elsewhere, it is important to test its cultural equivalence. Previous research suggested a lack of cultural equivalence testing in several areas of measurement. This paper reviews the process of cross-cultural equivalence testing of instruments to measure participation in society. An existing cultural equivalence framework was adapted and used to assess participation instruments on five categories of equivalence: conceptual, item, semantic, measurement and operational equivalence. For each category, several aspects were rated, resulting in an overall category rating of 'minimal/none', 'partial' or 'extensive'. The best possible overall study rating was five 'extensive' ratings. Articles were included if the instruments focussed explicitly on measuring 'participation' and were theoretically grounded in the ICIDH(-2) or ICF. Cross-validation articles were only included if it concerned an adaptation of an instrument developed in a high or middle-income country to a low-income country or vice versa. Eight cross-cultural validation studies were included in which five participation instruments were tested (Impact on Participation and Autonomy, London Handicap Scale, Perceived Impact and Problem Profile, Craig Handicap Assessment Reporting Technique, Participation Scale). Of these eight studies, only three received at least two 'extensive' ratings for the different categories of equivalence. The majority of the cultural equivalence ratings given were 'partial' and 'minimal/none'. The majority of the 'none/minimal' ratings were given for item and measurement equivalence. The cross-cultural equivalence testing of the participation instruments included leaves much to be desired. A detailed checklist is proposed for designing a cross-validation study. Once a study has been conducted, the checklist can

    OBJECT There is currently no consensus on the safety of sports participation for patients with Chiari I malformation (CM-I). The authors' goal was to define the risk of sports participation for children with the imaging finding of CM-I. METHODS A prospective survey was administered to 503 CM-I patients at 2 sites over a 46-month period. Data were gathered on imaging characteristics, treatment, sports participation, and any sport-related injuries. Additionally, 81 patients completed at least 1 subsequent survey following their initial entry into the registry and were included in a prospective group, with a mean prospective follow-up period of 11 months. RESULTS Of the 503 CM-I patients, 328 participated in sports for a cumulative duration of 4641 seasons; 205 of these patients participated in contact sports. There were no serious or catastrophic neurological injuries. One patient had temporary extremity paresthesias that resolved within hours, and this was not definitely considered to be related to the CM-I. In the prospective cohort, there were no permanent neurological injuries. CONCLUSIONS No permanent or catastrophic neurological injuries were observed in CM-I patients participating in athletic activities. The authors believe that the risk of such injuries is low and that, in most cases, sports participation by children with CM-I is safe.

    Currently, the engagement of local communities in Health Impact Assessment is becoming more and more important. A scoping review was performed to take stock of visions, methods and experiences in this field. A combined Scopus and Medline search yielded 100 articles in scientific journals. The final selection consisted of 43 papers, including case studies, evaluation studies, reviews, and opinion papers. After analysis, consultation of four experts was performed to check preliminary study outcomes. A grey literature web search was performed to check and complement the results. Results show that community participation is generally considered a core element in HIA. Views as expressed in the papers concern, firstly, the need for and value of local knowledge, secondly, the adherence to or application of democratic values and, thirdly, empowerment of communities. Three categories of methods are used in relation to community participation, often in combination: methods to facilitate knowledge elicitation, to ensure the inclusion of communities in the HIA process, and to build community capacity to participate in policy development. However, the theoretical or practical underpinning of the choice for specific methods is mostly not presented. The experiences described in the papers mainly focus on the access to local knowledge and its usability as a source of evidence in the HIA process. Described effects of community participation are (improved) relations between communities and local agencies, policy makers and professionals and the empowerment of community members. Although these effects are ascribed to community participation, many papers do not provide support for this conclusion beyond the retrospective perception of participants. Expert consultation and additional analysis of the grey literature supported the results derived from the scientific literature and provided more in-depth knowledge. In the grey literature theoretical frameworks, methods and tools for

    Primitive electronic waste (e-waste) recycling creates exposures to several hazardous substances including lead. In Uruguay, primitive recycling procedures are a significant source of lead exposure. The aim of this study was to examine lead exposure in blood lead levels (BLLs) in low-income children exposed to lead through burning cables. A sample of children and adolescents exposed to lead through burning cable activities were assessed at the Department of Toxicology in Montevideo, Uruguay, between 2010 and 2014. Soil lead levels of residences were taken shortly after their assessment. The final sample included 69 children and adolescents (mean age 7.89 years). More than 66% of participants had an additional source of lead exposure-manual gathering of metals-and based paint (r = 0.23; P source of lead exposure was the manual gathering of metals. The average BLL among children and adolescents in this study is higher than the BLLs currently suggested in medical intervention. Future research should focus on exploring effective interventions to reduce lead exposure among this vulnerable group. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

  18. Psychological restoration can depend on stimulus-source attribution: A challenge for the evolutionary account?

    Directory of Open Access Journals (Sweden)

    Andreas Haga

    2016-11-01

    Full Text Available Visiting or viewing nature environments can have restorative psychological effects, while exposure to the built environment typically has less positive effects. A classic view is that this difference in restorative potential of nature and built environments depends on differences in the intrinsic characteristics of the stimuli. In addition, an evolutionary account is often assumed whereby restoration is believed to be a hardwired response to nature’s stimulus-features. Here, we propose the novel hypothesis that the restorative effects of a stimulus do not entirely depend on the stimulus-features per se, but also on the meaning that people assign to the stimulus. Participants conducted cognitively demanding tests prior to and after a brief pause. During the pause, the participants were exposed to an ambiguous sound consisting of pink noise with white noise interspersed. Participants in the nature sound-source condition were told that the sound originated from a nature scene with a waterfall; participants in the industrial sound-source condition were told that the sound originated from an industrial environment with machinery; and participants in the control condition were told nothing about the sound origin. Self-reported mental exhaustion showed that participants in the nature sound-source condition were more psychologically restored after the pause than participants in the industrial sound-source condition. One potential interpretation of the results is that restoration from nature experiences depends on learned, positive associations with nature; not only on hardwired responses shaped by evolution.

    A nationwide survey of 1000 residences is underway to determine the sources and characteristics of magnetic fields in the home. This report describes the goals, statistical sampling methods, measurement protocols, and experiences in measuring the first 707 residences of the survey. Some preliminary analysis of the data is also included. Investigators designed a sampling method to randomly select the participating utilities as well as the residential customers for the study. As a first step in the project, 18 utility employee residences were chosen to validate a relatively simple measurement protocol against the results of a more complete and intrusive method. Using the less intrusive measurement protocol, researchers worked closely with representatives from EPRI member utilities to enter customer residences and measure the magnetic fields found there. Magnetic field data were collected in different locations inside and around the residences. Twenty-four-hour recorders were left in the homes overnight. Tests showed that the simplified measurement protocol is adequate for achieving the goals of the study. Methods were developed for analyzing the field caused by a residence's ground current, the lateral field profiles of field lines, and the field measured around the periphery of the residences. Methods of residential source detection were developed that allow identification of sources such as ground connections at an electrical subpanel, two-wire multiple-way switches, and underground or overhead net currents exiting the periphery of a residence

    The Philippine Nuclear Research Institute (PNRI), the national agency in the licensing and regulations of radioactive materials in the country, is strengthening its capabilities in the security of radioactive sources. Part of this program is the PNRI's participation in the Regional Security of Radioactive Sources (RSRS) Project of the Australian Nuclear Science and Technology Organization (ANSTO). The project has provided equipment and methods training, assistance in the development of PNRI's own training program and support for actual orphan source search activities. On May 2007, a source search for the two lost Cs-137 level gauges of a steel manufacturing company was conducted by the PNRI and ANSTO. The source search are the: a) Development of instrument and source search training for the team, the National Training Workshop on Orphan Source Searches which was organized and conducted as a result of train-the-trainors fellowship under the RSRS project; and b) Planning and implementation of the lost source search activity. The conduct of the actual search on warehouses, product yard, canals, dust storage, steel making building, scrap yards and nearby junk shops of the steel plant took one week. The week-long search did not find the lost sources. However, naturally occurring radioactive materials identified to be Thorium, were found on sands, bricks and sack piles that are stored and/or generally present in the warehouses, yard and steel making building. The search activity had therefore cleared the facility of the lost source and its corresponding hazards. The NORM found present in the plant's premises on the other hand brought the attention of the management of the needed measures to ensure safety of the staff from possible hazards of these materials. Currently, the course syllabus that was developed is continuously enhanced to accommodate the training needs of the PNRI staff particularly for the emergency response and preparedness.

It takes advantage of the power of the crowd, which can in some cases be a community of experts and in other cases the collective insight of a broader range of contributors with varying degrees of domain knowledge. The term crowd sourcing was first used by Jeff Howe in a June 2006 Wired magazine article “The Rise of Crowdsourcing,” and is a combination of the terms “crowd” and “outsourcing.” Some commonly known examples of crowd sourcing, in its broadest sense, include Wikepedia, distributed participatory design projects, and consumer websites such as Yelp and Angie’s List. The popularity and success of early large-scale crowd sourcing activities is made possible through leveraging Web 2.0 technologies that allow for mass participation from distributed individuals. The Earthquake Engineering Research Institute (EERI) in Oakland, California recently participated in two crowd sourcing projects. One was initiated and coordinated by EERI, while in the second case EERI was invited to contribute once the crowd sourcing activity was underway. In both projects there was: 1) the determination of a problem or set of tasks that could benefit immediately from the engagement of an informed volunteer group of professionals; 2) a segmenting of the problem into discrete pieces that could be completed in a short period of time (from ten minutes to four hours); 3) a call to action, where an interested community was made aware of the project; and 4) the collection, aggregation, vetting and ultimately distribution of the results in a relatively short period of time. The first EERI crowd sourcing example was the use of practicing engineers and engineering students in California to help estimate the number of pre-1980 concrete buildings in the high seismic risk counties in the state. This building type is known to perform poorly in earthquakes, and state officials were interested in understanding

    Full Text Available Abstract Background Although indicated prevention of depression is available for about 80% of the Dutch population at little or no cost, only a small proportion of those with subthreshold depression make use of these services. Methods A narrative review is conducted of the Dutch preventive services in mental health care, also addressing the problem of low participation rates. We describe possible causes of these low participation rates, which may be related to the participants themselves, the service system, and the communication to the public, and we put forward possible solutions to this problem. Results There are three main groups of reasons why the participation rates are low: reasons within the participants (e.g., not considering themselves as being at risk; thinking the interventions are not effective; or being unwilling to participate because of the stigma associated with depression; reasons within the health care system; and reasons associated with the communication about the preventive services. Possible solutions to increasing the participation rate include organizing mass media campaigns, developing internet-based preventive interventions, adapting preventive interventions to the needs of specific subpopulations, positioning the services in primary care, integrating the interventions in community-wide interventions, and systematically screening high-risk groups for potential participants. Discussion Prevention could play an important role in public mental health in reducing the enormous burden of depression. However, before this can be realized more research is needed to explore why participation rates are low and how these rates can be improved.

    Courses, including lectures, live surgery, and hands-on session, are part of the recommended curriculum for robotic surgery. However, for general surgery, this approach is poorly reported. The study purpose was to evaluate the impact of robotic general surgery course on the practice of participants. Between 2007 and 2011, 101 participants attended the Geneva International Robotic Surgery Course, held at the University Hospital of Geneva, Switzerland. This 2-day course included theory lectures, dry lab, live surgery, and hands-on session on cadavers. After a mean of 30.1 months (range, 2-48), a retrospective review of the participants' surgical practice was performed using online research and surveys. Among the 101 participants, there was a majority of general (58.4 %) and colorectal surgeons (10.9 %). Other specialties included urologists (7.9 %), gynecologists (6.9 %), pediatric surgeons (2 %), surgical oncologists (1 %), engineers (6.9 %), and others (5.9 %). Data were fully recorded in 99 % of cases; 46 % of participants started to perform robotic procedures after the course, whereas only 6.9 % were already familiar with the system before the course. In addition, 53 % of the attendees worked at an institution where a robotic system was already available. All (100 %) of participants who started a robotic program after the course had an available robotic system at their institution. A course that includes lectures, live surgery, and hands-on session with cadavers is an effective educational method for spreading robotic skills. However, this is especially true for participants whose institution already has a robotic system available.

    Medical schools wish to better understand why some students excel academically and others have difficulty in passing medical courses. Components of self-regulated learning (SRL), such as motivational beliefs and learning strategies, as well as participation in scheduled learning activities, have been found to relate to student performance. Although participation may be a form of SRL, little is known about the relationships among motivational beliefs, learning strategies, participation and medical school performance. This study aimed to test and cross-validate a hypothesised model of relationships among motivational beliefs (value and self-efficacy), learning strategies (deep learning and resource management), participation (lecture attendance, skills training attendance and completion of optional study assignments) and Year 1 performance at medical school. Year 1 medical students in the cohorts of 2008 (n = 303) and 2009 (n = 369) completed a questionnaire on motivational beliefs and learning strategies (sourced from the Motivated Strategies for Learning Questionnaire) and participation. Year 1 performance was operationalised as students' average Year 1 course examination grades. Structural equation modelling was used to analyse the data. Participation and self-efficacy beliefs were positively associated with Year 1 performance (β = 0.78 and β = 0.19, respectively). Deep learning strategies were negatively associated with Year 1 performance (β =- 0.31), but positively related to resource management strategies (β = 0.77), which, in turn, were positively related to participation (β = 0.79). Value beliefs were positively related to deep learning strategies only (β = 0.71). The overall structural model for the 2008 cohort accounted for 47% of the variance in Year 1 grade point average and was cross-validated in the 2009 cohort. This study suggests that participation mediates the relationships between motivation and learning strategies, and medical school

    Recruiting adolescent participants for research is challenging. The purpose of this study was to compare traditional in-person recruitment methods to social media recruitment. We recruited adolescents aged 14-18 years for a pilot physical activity intervention study, including a wearable physical activity tracking device and a Facebook group. Participants were recruited (a) in person from a local high school and an adolescent medicine clinic and (b) through social media, including Facebook targeted ads, sponsored tweets on Twitter, and a blog post. Data collected included total exposure (i.e., reach), engagement (i.e., interaction), and effectiveness. Effectiveness included screening and enrollment for each recruitment method, as well as time and resources spent on each recruitment method. In-person recruitment reached a total of 297 potential participants of which 37 enrolled in the study. Social media recruitment reached a total of 34,272 potential participants of which 8 enrolled in the study. Social media recruitment methods utilized an average of 1.6 hours of staff time and cost an average of $40.99 per participant enrolled, while in-person recruitment methods utilized an average of 0.75 hours of staff time and cost an average of $19.09 per participant enrolled. Social media recruitment reached more potential participants, but the cost per participant enrolled was higher compared to traditional methods. Studies need to consider benefits and downsides of traditional and social media recruitment methods based on study goals and population.

    The shape of the velocity distributions of charged particles projected on the beam direction can be explained if emissions from the hot projectile-like fragment and the target-like fragment are supplemented by an emission from an intermediate velocity source located between them. The creation of this source is predicted by a two-stage reaction model where, in the second stage, some of the nucleons identified in the first stage as participants form a group of clusters located in the region between the colliding nuclei. The cluster coalescence process is governed on the average by the maximum value of entropy, although its fluctuations are also significant. The properties of the intermediate velocity source are precisely described, including the isotopic composition of the emitted particles. (orig.)

    Volatile organic compounds (V.O.C.) are part of urban air pollution and are also generated indoors from cleaning and maintenance products. VOC measurements are, on average, 10 times higher within homes than outside. Results of the national survey led by the Observatoire National de la Qualité de l'Air Intérieur demonstrated that up to 25% of French homes have very high or high concentrations of VOC. Indoor levels depend mainly on indoor sources. Aldehydes are included in many everyday life products. VOC originate from various household decorating and cleaning products. Some products are less detrimental to the environment and health and have special labelling. Indoor VOC levels also depend on the rate of air exchange and on household characteristics such as indoor temperature and humidity, age of the building, presence of smokers, and communication with a garage. The public may participate in maintaining good indoor air quality and the authorities should also improve regulations. VOC are part of everyday air pollution. Their sources and concentrations should be better monitored.

    The M6 working group had more than 40 active participants (listed in Section 4). During the three weeks at Snowmass, there were about 50 presentations, covering a wide range of topics associated with high intensity proton sources. The talks are listed in Section 5. This group also had joint sessions with a number of other working groups, including E1 (Neutrino Factories and Muon Colliders), E5 (Fixed-Target Experiments), M1 (Muon Based Systems), T4 (Particle Sources), T5 (Beam dynamics), T7 (High Performance Computing) and T9 (Diagnostics). The M6 group performed a survey of the beam parameters of existing and proposed high intensity proton sources, in particular, of the proton drivers. The results are listed in Table 1. These parameters are compared with the requirements of high-energy physics users of secondary beams in Working Groups E1 and E5. According to the consensus reached in the E1 and E5 groups, the U.S. HEP program requires an intense proton source, a 1-4 MW Proton Driver, by the end of this decade.

    According to the documents model framework (Britt, Perfetti, Sandak, & Rouet, 1999), readers' detection of contradictions within texts increases their integration of source-content links (i.e., who says what). This study examines whether conflict may also strengthen the relationship between the respective sources. In two experiments, participants read brief news reports containing two critical statements attributed to different sources. In half of the reports, the statements were consistent with each other, whereas in the other half they were discrepant. Participants were tested for source memory and source integration in an immediate item-recognition task (Experiment 1) and a cued recall task (Experiments 1 and 2). In both experiments, discrepancies increased readers' memory for sources. We found that discrepant sources enhanced retrieval of the other source compared to consistent sources (using a delayed recall measure; Experiments 1 and 2). However, discrepant sources failed to prime the other source as evidenced in an online recognition measure (Experiment 1). We argue that discrepancies promoted the construction of links between sources, but that integration did not take place during reading.

    Receptiveness to interprofessional feedback, which is important for optimal collaboration, may be influenced by 'in-group or out-group' categorisation, as suggested by social identity theory. We used an experimental design to explore how nurses and resident physicians perceive feedback from people within and outside their own professional group. Paediatric residents and nurses participated in a simulation-based team exercise. Two nurses and two physicians wrote anonymous performance feedback for each participant. Participants each received a survey containing these feedback comments with prompts to rate (i) the usefulness (ii) the positivity and (iii) their agreement with each comment. Half of the participants received feedback labelled with the feedback provider's profession (two comments correctly labelled and two incorrectly labelled). Half received unlabelled feedback and were asked to guess the provider's profession. For each group, we performed separate three-way anovas on usefulness, positivity and agreement ratings to examine interactions between the recipient's profession, actual provider profession and perceived provider profession. Forty-five out of 50 participants completed the survey. There were no significant interactions between profession of the recipient and the actual profession of the feedback provider for any of the 3 variables. Among participants who guessed the source of the feedback, we found significant interactions between the profession of the feedback recipient and the guessed source of the feedback for both usefulness (F1,48 = 25.6; p feedback they guessed to be from nurses were higher than ratings of feedback they guessed to be from physicians, and vice versa. Among participants who received labelled feedback, we noted a similar interaction between the profession of the feedback recipient and labelled source of feedback for usefulness ratings (F1,92 = 4.72; p feedback to the in-group than to the out-group. This finding has potential

    Full Text Available Background: Pornography is now widespread and its use can have adverse consequences on everyday life, including daily routine, mental and physical health not only for individuals, but also those around them. In addition, sources of information about sexuality is an area that affects the sexual life of an individual. Aim: The aim of the present study was to investigate the use of pornographic material by adults, to evaluate the sexual behavior with respect to that and to find the main sources of sexual information. Methodology: The study involved 510 adults, age from 18 to 67. Data was collected after the completion of a specially designed anonymous electronic questionnaire, included 46 multiple-choice questions, exploring sexuality, use of pornography and sources of adult information. The promotion came through social media and the website of the Association for Regional Development and Mental Health. The statistical program SPSS Statistics 17.0 was used for the analysis of the data and the significance level was set at p<0.05 Results: Of the 510 participants of the sample of the research, 70,2% was women and 29,8% men, of mean age 26,7. Men watch an average of 3.49 times pornographic material per week, while women watched 0.49 times per week. Those who watched pornographic material more frequently had more sexual partners. A percentage of 60.1 % of men said that they watched pornography for masturbation and stimulation, while the majority of women (46.8 % said that curiosity was the main reason. The 72.7% of men rated pornographic material as stimulating while 39.9% of women characterized it as indifferent and stimulant. The majority of men (53.3 % and women (62% have been informed about sexuality by their friendly environment, but when the main source of information was internet, the age of onset of sexual contact was 10 to 16 years. Conclusions: Men watch more frequently pornography than women. Individuals watching several times pornographic

  3. Source memory enhancement for emotional words.

    Doerksen, S; Shimamura, A P

    2001-03-01

    The influence of emotional stimuli on source memory was investigated by using emotionally valenced words. The words were colored blue or yellow (Experiment 1) or surrounded by a blue or yellow frame (Experiment 2). Participants were asked to associate the words with the colors. In both experiments, emotionally valenced words elicited enhanced free recall compared with nonvalenced words; however, recognition memory was not affected. Source memory for the associated color was also enhanced for emotional words, suggesting that even memory for contextual information is benefited by emotional stimuli. This effect was not due to the ease of semantic clustering of emotional words because semantically related words were not associated with enhanced source memory, despite enhanced recall (Experiment 3). It is suggested that enhancement resulted from facilitated arousal or attention, which may act to increase organization processes important for source memory.

    We analysed the degree and impact of consent bias in the prospective study 'leben in der Arbeit (lidA)' after linking primary interview data with claims data from German statutory health insurance funds as well as with administrative data provided by the German Federal Employment Agency. Prospective cohort study. Within two study waves (2011, 2014) primary data were collected based on computer-assisted personal interviews. During interview informed consent to data linkage was obtained. We used binary logistic regression analyses with participants' consent for record linkage as the dependent variable calculating odds ratios (ORs) and 95% confidence intervals (95% CIs) for independent variables. Several sociodemographic, socio-economic and work-related factors were modelled as potential determinants of consent. A total of 4244 participants took part in both waves. After excluding invalid consent, 4178 participants were included in the analysis. About 3918 (93.8%) of these participants gave their consent to link their primary data with data from at least one source. Within regression analyses only moderate bias was found due to region of residence, apprenticeship, professional affiliations, income and number of diseases. Participants from former West Germany were less likely to have their study data linked with both data sources (OR 0.63 [95% CI 0.42-0.96]) than those from the former East Germany. Participants with no information on income were more likely to refuse consent to both data sources compared to the reference group (net income: under EUR 1000; OR 0.15 [95% CI 0.08-0.30]). Respondents with two (OR 1.37 [95% CI 1.06-1.77]) or three and more diseases (OR 1.30 [95% CI 1.02-1.66]) diagnosed by a doctor agreed more frequently to linking both data sources than participants without disease. There is just a small proportion of variance in consenting explained by the models (R 2 : 0.063-0.085). Also, only small changes of factors' prevalence were observed in

    Happiness and exhilaration are the most essential demands of human innate psychological needs that affect both physical and mental health. The present study aimed to investigate the effect of individual factors, socioeconomic and social participation on individual happiness. In this study, we evaluated 15 to 54-year-old individuals to find the effects of individual factors, socioeconomic and social partnership (formal or informal) on human happiness. A random sampling method was used in the present study. The Oxford Happiness Questionnaire (OHQ) was used. Data analysis was performed using descriptive statistics including; frequency, percentage, Mean±SD. Correlation coefficient, one way ANOVA and logistic regression were also used as analytical statistics. There was a significant relationship between gender (p=0.001, r=0.144), marital status (p=0.001, r=0.174), happy parents (p=0.001, r=0.194), educational grade (p=0.001, r=0.189), employment status (p=0.001, r=0.180), income (p=0.001, r=0.264), car ownership (p=0.001, r=0.173), informal social participation (p=0.001, r=0.3) and formal social participation (p=0.001, r=0.231) with happiness. However, the relationship between home ownership (p=0.346, r=-0.015), and happiness was not significant. It seems that good and cordial relations with others, including family, relatives and friends (informal social participation) are the main sources and the most important factors of life satisfaction and human happiness. Higher income can increase happiness by enhancing the possibility to access the needs, desires, problems solving, enhancing the social support and self esteem and opportunities to perform one's favourite activities.

    Bell, Raoul; Giang, Trang; Buchner, Axel

    2012-01-01

    Previous research has shown a source memory advantage for faces presented in negative contexts. As yet it remains unclear whether participants remember the specific type of context in which the faces were presented or whether they can only remember that the face was associated with negative valence. In the present study, participants saw faces together with descriptions of two different types of negative behaviour and neutral behaviour. In Experiment 1, we examined whether the participants were able to discriminate between two types of other-relevant negative context information (cheating and disgusting behaviour) in a source memory test. In Experiment 2, we assessed source memory for other-relevant negative (threatening) context information (other-aggressive behaviour) and self-relevant negative context information (self-aggressive behaviour). A multinomial source memory model was used to separately assess partial source memory for the negative valence of the behaviour and specific source memory for the particular type of negative context the face was associated with. In Experiment 1, source memory was specific for the particular type of negative context presented (i.e., cheating or disgusting behaviour). Experiment 2 showed that source memory for other-relevant negative information was more specific than source memory for self-relevant information. Thus, emotional source memory may vary in specificity depending on the degree to which the negative emotional context is perceived as threatening.

  8. Clinical trial participation. Viewpoints from racial/ethnic groups.

    Racial/ethnic groups' participation in clinical trials is a relatively new area of research that warrants attention. Although racial/ethnic groups have been included in experimental studies since the 1940s, they were not included in significant numbers in clinical trials for cancer. Clinical trials play a dominant role in clinical oncology. Despite this state-of-the-art cancer treatment, however, there is mounting concern that this scientific progress is not being shared equitably by all segments of the U.S. population. There is underrepresentation of members of racial/ethnic groups in cancer clinical trials, which suggests that participation may be a critical issue. Unfortunately, little is known or documented about these groups' participation in clinical trials. This paper discusses racial/ethnic groups' views and opinions about clinical trial participation. Diagnostic research was conducted as a beginning phase to investigate this new area of research. African Americans, Hispanics, and Native Americans in three Buffalo, New York, communities were selected as study subjects. Data were collected via telephone surveys. Qualitative methods were employed for data analysis and reporting. Findings showed that study subjects knew little about cancer clinical trials and basically had no opportunity to participate. They believed that participation in clinical trials could be beneficial. In each of the three groups, however, there were cultural factors believed to influence participation. A primary concern was "mistrust of white people" and the feeling of being treated like "guinea pigs." Based on study findings, it was evident that recruitment for improving participation requires strategic planning that involves participants representative of the study population. To yield results, the plan should be tailored to the target group, presented as a credible study, designed to reflect trust in the medical care team, and implemented through a continuous educational process.

    To describe the success of diverse recruitment methods in a randomized controlled clinical trial of exercise in persons with peripheral arterial disease (PAD). An analysis of recruitment sources conducted for the 746 men and women completing a baseline visit for the study to improve leg circulation (SILC), a randomized controlled trial of exercise for patients with PAD. For each recruitment source, we determined the number of randomized participants, the rate of randomization among those completing a baseline visit, and cost per randomized participant. Of the 746 individuals who completed a baseline visit, 156 were eligible and randomized. The most frequent sources of randomized participants were newspaper advertising (n = 67), mailed recruitment letters to patients with PAD identified at the study medical center (n = 25), and radio advertising (n = 18). Costs per randomized participant were $2750 for television advertising, $2167 for Life Line Screening, $2369 for newspaper advertising, $3931 for mailed postcards to older community dwelling men and women, and $5691 for radio advertising. Among those completing a baseline visit, randomization rates ranged from 10% for those identified from radio advertising to 32% for those identified from the Chicago Veterans Administration and 33% for those identified from posted flyers. Most participants in a randomized controlled trial of exercise were recruited from newspaper advertising and mailed recruitment letters to patients with known PAD. The highest randomization rates after a baseline visit occurred among participants identified from posted flyers and mailed recruitment letters to PAD patients.

    We investigated the role of emotion on item and source memory using the item method of directed forgetting (DF) paradigm. We predicted that emotion would produce source memory impairment because emotion would make it more difficult to distinguish between to-be-remembered (R items) and to-be-forgotten items (F items) by making memory strength of R and F items similar to each other. Participants were presented with negatively arousing, positively arousing, and neutral pictures. After each picture, they received an instruction to remember or forget the picture. At retrieval, participants were asked to recall both R and F items and indicate whether each item was an R or F item. Recall was higher for the negatively arousing than for the positively arousing or neutral pictures. Further, DF occurred for the positively arousing and neutral pictures, whereas DF was not significant for the negatively arousing pictures. More importantly, the negatively arousing pictures, particularly the ones with violent content, showed a higher tendency of producing misattribution errors than the other picture types, supporting the notion that negative emotion may produce source memory impairment, even though it is still not clear whether the impairment occurs at encoding or retrieval. ©2011 The British Psychological Society.

  11. From voice to voices: identifying a plurality of Muslim sources in the news media.

    Science.gov (United States)

    Munnik, Michael B

    2017-03-01

    This article identifies a qualitative change in the diversity of actors who represent Muslims in British news media. Hitherto, the literature discussing Muslims and the media has tended to characterize media organizations as institutions which portray Muslims in an essentialized, monolithic way. In contrast, I propose in this article that the process of representation is more complex, including greater agency and engaging a wider diversity of Muslims than the prevailing literature suggests. Sociological studies distinguish between official and unofficial sources who help determine the representations that journalists employ in their texts, and I apply this to Muslim communities in Glasgow. Using qualitative methods drawn from media production analysis, including participant-observation and ethnographic interviews, I identify a shift from a 'gatekeeper' model of representing the community to that of a plurality of sources, which reveals and insists on the diversity of Muslim communities and voices. I will show why a wider range of actors emerged to speak publicly, what differentiates them and how they position themselves as representatives of Muslims. This focus on producers and on source strategies brings fresh insights into a field dominated by content analysis and a 'media-centric' approach.

  12. Dynamic Stock Market Participation of Households with Heterogeneous Participation Costs

    Khorunzhina, Natalia

    This paper develops and estimates a dynamic model of stock market participation, where consumers’ decisions regarding stock market participation are influenced by participation costs. The practical significance of the participation costs is considered as being a channel through which financial...... education programs can affect consumers’ investment decisions. Using household data from the Panel Study of Income Dynamics, I estimate the magnitude of the participation cost, allowing for individual heterogeneity in it. The results show the average stock market participation cost is about 5% of labor...... income; however, it varies substantially over consumers’ life. The model successfully predicts the level of the observed participation rate and the increasing pattern of stock market participation over the consumers’ life cycle....

    To critically analyze studies published within the past decade about participants' comprehension of informed consent in clinical research and to identify promising intervention strategies. Integrative review of literature. The Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, and the Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials were searched. Inclusion criteria included studies (a) published between January 1, 1996 and January 1, 2007, (b) designed as descriptive or interventional studies of comprehension of informed consent for clinical research, (c) conducted in nonpsychiatric adult populations who were either patients or volunteer participants, (d) written in English, and (e) published in peer-reviewed journals. Of the 980 studies identified, 319 abstracts were screened, 154 studies were reviewed, and 23 met the inclusion criteria. Thirteen studies (57%) were descriptive, and 10 (43%) were interventional. Interventions tested included simplified written consent documents, multimedia approaches, and the use of a trained professional (consent educator) to assist in the consent process. Collectively, no single intervention strategy was consistently associated with improved comprehension. Studies also varied in regard to the definition of comprehension and the tools used to measure it. Despite increasing regulatory scrutiny, deficiencies still exist in participant comprehension of the research in which they participate, as well as differences in how comprehension is measured and assessed. No single intervention was identified as consistently successful for improving participant comprehension, and results indicated that any successful consent process should at a minimum include various communication modes and is likely to require one-to-one interaction with someone knowledgeable about the study.

    selection and involvement of stakeholders. One issue is the requirements for, but also if there are any limitations of, the use of novel public participation approaches (as compared to traditional minimal participation such as receiving information, asking questions at public meetings and submitting written comments) within the legal systems. Initially, the basic method of the work package was thus to analyze information gathered by the questionnaire survey. It was later decided to include more of external sources of information in the review such as other governance projects supported by DG Research of the European Commission. Furthermore, a study made on the legal aspects of information and participation in the nuclear sector made by the University of Aberdeen in a contract with DG TREN in 2005-2006 gave starting point for the WP 1 work Paterson et al. This study stays with strict legal requirements and in the discussion in this report we go deeper into how they are practiced with regard to participation and transparency. The decision to complement the survey by taking other sources of information into account and referring to them was made partly to avoid unnecessary duplication of work and partly as the questionnaire responses were fewer than expected. In the end, it is believed that this approach made the work and thus this report richer than otherwise would been the case. This report was concluded with a combination of efforts from Karita and the Joint Research Centre (JRC). In Chapter 2 we give more details on the relevant international agreements, thus mainly referring to the DG TREN report when it comes to national legislation. In chapter 3 we summarize the results from the survey with regard to driving forces behind efforts for participation and transparency, current practices and future needs. Finally, in Chapter 4 we discuss the situation taking both formal requirements, as described in chapter 3 and in the DG TREN report, and the survey responses into account

    Full Text Available Trust is essential to understanding public reaction to innovative issues. This research focuses on trust in information sources by explicating the construct of trust and testing a comprehensive model on several information sources about genetically modified foods. Results from a survey of 369 participants reveal the significance of projecting competence and the role of the environment in which a target public receives information. Perceptions of regulatory, social, business, and technical environments affect how likely individuals are to follow advice from institutions like the Food and Drug Administration and the news media. Future research should incorporate knowledge levels and personal relevance as variables likely to influence trusting relationships.

  19. Source-based neurofeedback methods using EEG recordings: training altered brain activity in a functional brain source derived from blind source separation

    White, David J.; Congedo, Marco; Ciorciari, Joseph

    2014-01-01

    A developing literature explores the use of neurofeedback in the treatment of a range of clinical conditions, particularly ADHD and epilepsy, whilst neurofeedback also provides an experimental tool for studying the functional significance of endogenous brain activity. A critical component of any neurofeedback method is the underlying physiological signal which forms the basis for the feedback. While the past decade has seen the emergence of fMRI-based protocols training spatially confined BOLD activity, traditional neurofeedback has utilized a small number of electrode sites on the scalp. As scalp EEG at a given electrode site reflects a linear mixture of activity from multiple brain sources and artifacts, efforts to successfully acquire some level of control over the signal may be confounded by these extraneous sources. Further, in the event of successful training, these traditional neurofeedback methods are likely influencing multiple brain regions and processes. The present work describes the use of source-based signal processing methods in EEG neurofeedback. The feasibility and potential utility of such methods were explored in an experiment training increased theta oscillatory activity in a source derived from Blind Source Separation (BSS) of EEG data obtained during completion of a complex cognitive task (spatial navigation). Learned increases in theta activity were observed in two of the four participants to complete 20 sessions of neurofeedback targeting this individually defined functional brain source. Source-based EEG neurofeedback methods using BSS may offer important advantages over traditional neurofeedback, by targeting the desired physiological signal in a more functionally and spatially specific manner. Having provided preliminary evidence of the feasibility of these methods, future work may study a range of clinically and experimentally relevant brain processes where individual brain sources may be targeted by source-based EEG neurofeedback.

    Full Text Available The aim of the paper is to provide guidance on conducting participant and non-participant observation studies of information behaviour. Examines lessons learned during non-participant observation of hospital pharmacists, and participant observation with dependent older people living in their own homes. Describes the methods used in both studies, and discusses the ethical issues involved in gaining access to the subjects. In the hospital setting, professional affiliation between the researcher and the subjects (six pharmacists made access easier to obtain. In the home care setting, access to subjects (seven clients for participant observation (as a care worker was more difficult, as was withdrawal from the field study. In both studies, the observation element was triangulated with survey data. Both studies indicated the fundamental need for trust between the observer and the research subjects. In some situations, professional relations offer instant access and trust, whereas in closed and sensitive situations such as social care, time is required to build up trust. With participant observation, that trust should not be damaged by withdrawal of the researcher from the research setting.

    Indigenous elders have traditionally played an important role in maintaining social cohesion within their communities. Today, part of this role has been taken over by government social and healthcare services, but they are having limited success in addressing social challenges. Increasing elders' social participation and intergenerational solidarity might foster community development and benefit young people, families, communities and the elders themselves. However, knowledge of the contribution of elders' social participation and intergenerational solidarity to wellness is scattered and needs to be synthesised. This protocol presents a scoping review on the social participation of indigenous elders, intergenerational solidarity and their influence on individual and community wellness. This scoping review protocol is based on an innovative methodological framework designed to gather information from the scientific and grey literature and from indigenous sources. It was developed by an interdisciplinary team including indigenous scholars/researchers, knowledge users and key informants. In addition to searching information databases in fields such as public health and indigenous studies, an advisory committee will ensure that information is gathered from grey literature and indigenous sources. The protocol was approved by the Ethics Review Board of the Université du Québec en Abitibi-Témiscamingue and the First Nations of Quebec and Labrador Health and Social Services Commission. The comprehensive synthesis of the scientific and grey literature and indigenous sources proposed in this protocol will not only raise awareness within indigenous communities and among healthcare professionals and community organisations, but will also enable decision-makers to better meet the needs of indigenous people. The innovative methodological framework proposed in this scoping review protocol will yield richer information on the contribution of elders to community wellness. This

    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

    Water is the source of life needed by living things. Human as one of living most in needs of water. Because the population growth follows the geometrical progression, while the natural resource increases calculates the arithmetic. Humans besides needing water also need land for shelter and for their livelihood needs, such as gardening or rice farmers. If the water absorption area is reduced, water availability will decrease. Therefore it is necessary to conduct an in-depth study of water resources management involving the community. The purpose of this study is to analyze community participation in water resources management, so that its availability can still meet the needs of living and sustainable. The method that used the level of community participation according to Arstein theory. The results obtained that community participation is at the level of partnership and power delegation. This level of participation is at the level of participation that determines the sustainability of water resources for present and future generations.

    2004-01-01

    The participants at the Conference called on decision makers both in the European Union (EU) and in Slovakia to provide fair treatment to nuclear power compared with other energy sources, especially with renewable, without prejudice to nuclear safety. This implies ensuring equality in terms of economics, tax, and accounting for externalities. The participants called on the Slovak government to initiate studies that compare the full life-cycle costs, impacts and risks, across the spectrum of energy sources and uses. They should also internalize the external costs. The participants called for a debate on the Slovak energy needs, taking into account the environmental impact of all potential sources of energy and the costs of providing electricity from those sources, and in addition a rational and objective analysis of the security of supply of those sources. It is necessary to have a range of sources for electricity generation that are cost effective and reliable, and respect the environment. The Slovak economy cannot withstand a sudden loss of its guaranteed energy supply. The participants believe that the major government role is setting overall policy for the economy, energy and the environment, with an adequate base in legislation and institutional competence. The Slovak government should have clear strategies for achieving self-sufficient energy-policy goals with reserve power and for meeting climate-change and air-quality goals. The Conference concluded that the nuclear option should remain open in Slovakia, as part of a balanced energy mix, in line with developments abroad and the EU Green Paper from 2000; the alternative is Slovak's failure to secure an affordable energy supply for its citizens. The participants supported the completion of Mochovce 3, 4, complying with enhanced safety requirements, as the most effective option. In Slovenske elektrarne, a.s.

    Inadequate functional health literacy is a common problem in immigrant populations. The aim of this study was to investigate the association between oral (dental) health literacy (OHL) and participation in oral health care among Brazilian immigrants in Toronto, Ontario, Canada. The study used a cross-sectional design and a convenience sample of 101 Brazilian immigrants selected through the snowball sampling technique. Data were analyzed using descriptive statistics and logistic regression modeling. Most of the sample had adequate OHL (83.1 %). Inadequate/marginal OHL was associated with not visiting a dentist in the preceding year (OR = 3.61; p = 0.04), not having a dentist as the primary source of dental information (OR = 5.55; p < 0.01), and not participating in shared dental treatment decision making (OR = 1.06; p = 0.05; OHL as a continuous variable) in multivariate logistic regressions controlling for covariates. A low average annual family income was associated with two indicators of poor participation in oral health care (i.e., not having visited a dentist in the previous year, and not having a dentist as regular source of dental information). Limited OHL was linked to lower participation in the oral health care system and with barriers to using dental services among a sample of Brazilian immigrants. More effective knowledge transfer will be required to help specific groups of immigrants to better navigate the Canadian dental care system.

    Full Text Available Source memory, the ability to identify the context in which a memory occurred, is impaired in schizophrenia and has been related to clinical symptoms such as hallucinations. The neurobiological underpinnings of this deficit are not well understood. Twenty-five patients with recent onset schizophrenia (within the first 4.5 years of treatment and twenty-four healthy controls completed a source memory task. Participants navigated through a 3D virtual city, and had 20 encounters of an object with a person at a place. Functional magnetic resonance imaging was performed during a subsequent forced-choice recognition test. Two objects were presented and participants were asked to either identify which object was seen (new vs. old object recognition, or identify which of the two old objects was associated with either the person or the place being presented (source memory recognition. Source memory was examined by contrasting person or place with object. Both patients and controls demonstrated significant neural activity to source memory relative to object memory, though activity in controls was much more widespread. Group differences were observed in several regions, including the medial parietal and cingulate cortex, lateral frontal lobes and right superior temporal gyrus. Patients with schizophrenia did not differentiate between source and object memory in these regions. Positive correlations with hallucination proneness were observed in the left frontal and right middle temporal cortices and cerebellum. Patients with schizophrenia have a deficit in the neural circuits which facilitate source memory, which may underlie both the deficits in this domain and be related to auditory hallucinations.

    The functional food industry has experienced innovative and economic expansion, yet research into consumer perceptions of functional foods and their associated health claims is limited. Among consumers, older adults could benefit from functional foods due to age-related issues pertaining to food and health. The purpose of this research was to identify the need for information related to functional foods among older adults (≥60 years old) and to assess awareness and perceptions of health claims on functional food packages. Community-dwelling older adults (n = 200) completed a researcher administered questionnaire designed to collect information about functional foods including current consumption, motivating factors for consumption, perceived need for information, sources of information for functional foods and awareness of health claims. Prevalence of functional food consumption among participants was 93.0%. Increased awareness and knowledge was the most commonly reported factor that would promote functional food consumption (85.5%) and 63.5% of participants wanted more information about functional foods with preferred sources being newspapers/magazines/books (68.5%) and food labels (66.1%). Participants were predominately (93.5%) aware of health claims on functional foods and those with more education were more likely to report being aware of health claims (p = 0.045). Although functional food consumption among older adults in this sample is high, there is a need for further information regarding functional foods. These results inform stakeholders regarding the potential for information to influence functional food acceptance among older adult consumers.

    The Chandra Source Catalog (CSC) is intended to be the definitive catalog of all X-ray sources detected by Chandra. For each source, the CSC provides positions and multi-band fluxes, as well as derived spatial, spectral, and temporal source properties. Full-field and source region data products are also available, including images, photon event lists, light curves, and spectra. The Chandra X-ray Center CSC website (http://cxc.harvard.edu/csc/) is the place to visit for high-level descriptions of each source property and data product included in the catalog, along with other useful information, such as step-by-step catalog tutorials, answers to FAQs, and a thorough summary of the catalog statistical characterization. Eight categories of detailed catalog documents may be accessed from the navigation bar on most of the 50+ CSC pages; these categories are: About the Catalog, Creating the Catalog, Using the Catalog, Catalog Columns, Column Descriptions, Documents, Conferences, and Useful Links. There are also prominent links to CSCview, the CSC data access GUI, and related help documentation, as well as a tutorial for using the new CSC/Google Earth interface. Catalog source properties are presented in seven scientific categories, within two table views: the Master Source and Source Observations tables. Each X-ray source has one ``master source'' entry and one or more ``source observation'' entries, the details of which are documented on the CSC ``Catalog Columns'' pages. The master source properties represent the best estimates of the properties of a source; these are extensively described on the following pages of the website: Position and Position Errors, Source Flags, Source Extent and Errors, Source Fluxes, Source Significance, Spectral Properties, and Source Variability. The eight tutorials (``threads'') available on the website serve as a collective guide for accessing, understanding, and manipulating the source properties and data products provided by the catalog.

    Edelmann, Noella; Hoechtl, Johann; Parycek, Peter

    In Austria, two recent eParticipation projects focused on adolescent citizens. The first project, “mitmachen.at - move your future” was to provide initial experiences with an eParticipation tool. The second project, “Jugend2help”, applied the lessons learned from the “mitmachen.at” project to improve the Austrian public administration web portal for adolescent citizens. In both projects, the results indicate that web portals and eParticpation seems to suit the adolescents’ information and communication needs. Involving the users is central to the development of an eParticipation process or platform so that the users’ specific characteristics (age, skills), needs and interests are included appropriately. The target users’ characteristics are also important for developing a marketing strategy which is able to reach them. Other issues which must also be considered in eParticipation are accessibility, inclusion and possibly gender.

    This study explored concurrent effects of six work psychosocial factors on current participation and the self-reported likelihood of future participation in workplace wellness programs using a cross-sectional survey, an ad hoc focus group, and structured interviews. Classification and regression tree analysis was used to analyze survey responses from 343 employees (194 nonparticipants, 95 participants, and 54 engaged participants). A thematic analysis of focus group ( n = 7) and interview ( n = 5) narratives was also undertaken. In combination with high work control, high superior support was associated with an engaged participant profile. Job demand was the third important variable with low and very high levels associated with participation. With regard to high likelihood of future participation, among respondents with age older than 50, high predictability of occupational activities and control were identified as a significant factor, and among others, high superior support and control. The analysis of narratives revealed peer relations and flexible working hours to be positively linked to participation and general job stress was identified as having a bidirectional relationship. Employees stated that stress led them to take advantage of these programs as a source of relief and that their availability/participation has contributed to lowering their stress. These findings inform practitioners about the importance of addressing poor psychosocial factors as a participation barrier and having a holistic approach to employee well-being.

    2009-01-01

    Full Text Available This study presents the differences of competition between mini-basketball with the traditional rules (5-a-side and minibasket with rule modifications (3-a-side such as: reduced number of players on court, compulsory participation in 2 of the match's 4 periods, reduced court size, placing the free throw line at 3m from the basket, and including a three-point line. The sample that was selected included 47 mini-basketball players, and the study was carried out using a quasi-experimental design without a control group. The aim was to determine the effect of rule modifications on the participation of the player with the ball. It was demonstrated that the degree of individual participation is greater in mini-basketball with modified rules.

    Regular participation in resistance training is important for older people to maintain their health and independence, yet participation rates are low. The study aimed to identify motivators and barriers to older people participating in resistance training. A systematic review was conducted including quantitative, qualitative, and mixed-method studies. Searches generated 15,920 citations from six databases, with 14 studies (n = 1,937 participants) included. In total, 92 motivators and 24 barriers were identified. Motivators specific to participating in resistance training included preventing deterioration (disability), reducing risk of falls, building (toning) muscles, feeling more alert, and better concentration. Looking too muscular and thinking participation increased the risk of having a heart attack, stroke, or death, despite the minimal likelihood of these occurring, were barriers. The analysis indicates that increasing participation in resistance training among older people should focus on the specific benefits valued by older people and the dissemination of accurate information to counter misperceptions.

    As the electric sector evolves and increasing amounts of variable renewable generation are installed on the system, there are greater needs for system flexibility and sufficient capacity, and greater concern for overgeneration from renewable sources not well matched in time with electric loads. Hydrogen systems have the potential to support the grid in each of these areas. However, limited information is available about the economic competitiveness of hydrogen system configurations. This paper quantifies the value for hydrogen energy storage and demand response systems to participate in select California wholesale electricity markets using 2012 data. For hydrogen systems and conventional storage systems (e.g., pumped hydro, batteries), the yearly revenues from energy, ancillary service, and capacity markets are compared to the yearly cost to establish economic competitiveness. Hydrogen systems can present a positive value proposition for current markets. Three main findings include: (1) For hydrogen systems participating in California electricity markets, producing and selling hydrogen was found to be much more valuable than producing and storing hydrogen to later produce electricity; therefore systems should focus on producing and selling hydrogen and opportunistically providing ancillary services and arbitrage. (2) Tighter integration with electricity markets generates greater revenues (i.e., systems that participate in multiple markets receive the highest revenue). (3) More storage capacity, in excess of what is required to provide diurnal shifting, does not increase competitiveness in current California wholesale energy markets. As more variable renewable generation is installed, the importance of long duration storage may become apparent in the energy price or through additional markets, but currently, there is not a sufficiently large price differential between days to generate enough revenue to offset the cost of additional storage. Future work will involve

  9. Source memory in the absence of successful cued recall.

    Cook, Gabriel I; Marsh, Richard L; Hicks, Jason L

    2006-07-01

    Five experiments were conducted to address the question of whether source information could be accessed in the absence of being able to recall an item. The authors used a paired-associate learning paradigm in which cue-target word pairs were studied, and target recall was requested in the presence of the cue. When target recall failed, participants were asked to make a source judgment of whether a man or woman spoke the unrecalled item. In 3 of the 5 experiments, source accuracy was at or very close to chance. By contrast, if cue-target pairs were studied multiple times or participants knew in advance of learning that a predictive judgment would be required, then predictive source accuracy was well above chance. These data are suggestive that context information may not play a very large role in metacognitive judgments such as feeling-of-knowing ratings or putting one into a tip-of-the-tongue state without strong and specific encoding procedures. These same results also highlight the important role that item memory plays in retrieving information about the context in which an item was experienced. Copyright 2006 APA, all rights reserved.

    2017-03-01

    The current study examined whether the effect of post-encoding emotional arousal on item memory extends to reality-monitoring source memory and, if so, whether the effect depends on emotionality of learning stimuli and testing format. In Experiment 1, participants encoded neutral words and imagined or viewed their corresponding object pictures. Then they watched a neutral, positive, or negative video. The 24-hour delayed test showed that emotional arousal had little effect on both item memory and reality-monitoring source memory. Experiment 2 was similar except that participants encoded neutral, positive, and negative words and imagined or viewed their corresponding object pictures. The results showed that positive and negative emotional arousal induced after encoding enhanced consolidation of item memory, but not reality-monitoring source memory, regardless of emotionality of learning stimuli. Experiment 3, identical to Experiment 2 except that participants were tested only on source memory for all the encoded items, still showed that post-encoding emotional arousal had little effect on consolidation of reality-monitoring source memory. Taken together, regardless of emotionality of learning stimuli and regardless of testing format of source memory (conjunction test vs. independent test), the facilitatory effect of post-encoding emotional arousal on item memory does not generalize to reality-monitoring source memory.

  11. Assessing the impact participation in science journalism activities has on scientific literacy among high school students

    Farrar, Cathy

    As part of the National Science Foundation Science Literacy through Science Journalism (SciJourn) research and development initiative (http://www.scijourn.org ; Polman, Saul, Newman, and Farrar, 2008) a quasi-experimental design was used to investigate what impact incorporating science journalism activities had on students' scientific literacy. Over the course of a school year students participated in a variety of activities culminating in the production of science news articles for Scijourner, a regional print and online high school science news magazine. Participating teachers and SciJourn team members collaboratively developed activities focused on five aspects of scientific literacy: placing information into context, recognizing relevance, evaluating factual accuracy, use of multiple credible sources and information seeking processes. This study details the development process for the Scientific Literacy Assessment (SLA) including validity and reliability studies, evaluates student scientific literacy using the SLA, examines student SLA responses to provide a description of high school students' scientific literacy, and outlines implications of the findings in relation to the National Research Council's A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012) and classroom science teaching practices. Scientifically literate adults acting as experts in the assessment development phase informed the creation of a scoring guide that was used to analyze student responses. Experts tended to draw on both their understanding of science concepts and life experiences to formulate answers; paying close attention to scientific factual inaccuracies, sources of information, how new information fit into their view of science and society as well as targeted strategies for information seeking. Novices (i.e., students), in contrast, tended to ignore factual inaccuracies, showed little understanding about source credibility and suggested

(ii) To compare food supply and actions between participating and non-participating schools. (iii) To investigate what reasons schools have to increase attention for nutrition in the curriculum. A cross-sectional study based on information from questionnaires performed in 2010/2011. All secondary schools (age group 12-18 years) in the Netherlands (n 1145). Response was 33 % (n 375). Analyses included all schools with a canteen in which food is offered (28 %, n 325). None of the investigated determinants was associated with participation. Participating schools offered significantly (P schools. However, there was no difference in the number of less healthy products offered (e.g. candy bars, cakes and regular soft drinks). Participating schools reported more often that they took actions to improve dietary behaviour and more often had a policy on nutrition. Participating schools more often increased attention for nutrition in the curriculum in recent years than non-participating schools (57 % v. 43 %, P = 0·01). Reported reasons were similar and included media attention, eating behaviour of students and 'overweight'. Schools that participate in the programme seemed to offer more healthy products in their canteens and took more actions to improve dietary behaviour than non-participating schools. However, at all schools less healthy foods were also available.

    Paul T Shattuck

    Full Text Available Little is known about patterns of participation in social activities among adolescents with an autism spectrum disorder (ASD. The objectives were to report nationally representative (U.S. estimates of participation in social activities among adolescents with an ASD, to compare these estimates to other groups of adolescents with disabilities, and examine correlates of limited social participation.We analyzed data from wave 1 of the National Longitudinal Transition Study 2, a large cohort study of adolescents enrolled in special education. Three comparison groups included adolescents with learning disabilities, mental retardation, and speech/language impairments. Adolescents with an ASD were significantly more likely never to see friends out of school (43.3%, never to get called by friends (54.4%, and never to be invited to social activities (50.4% when compared with adolescents from all the other groups. Correlates of limited social participation included low family income and having impairments in conversational ability, social communication, and functional cognitive skills.Compared with prior research, our study significantly expands inquiry in this area by broadening the range of social participation indicators examined, increasing the external validity of findings, focusing on the under-studied developmental stage of adolescence, and taking an ecological approach that included many potential correlates of social participation. There were notable differences in social participation by income, a dimension of social context seldom examined in research on ASDs.

    A variety of H{sup -} ion sources are in use at accelerator laboratories around the world. A list of these ion sources includes surface plasma sources with magnetron, Penning and surface converter geometries as well as magnetic-multipole volume sources with and without cesium. Just as varied is the means of igniting and maintaining magnetically confined plasmas. Hot and cold cathodes, radio frequency, and microwave power are all in use, as well as electron tandem source ignition. The extraction systems of accelerator H{sup -} ion sources are highly specialized utilizing magnetic and electric fields in their low energy beam transport systems to produce direct current, as well as pulsed and/or chopped beams with a variety of time structures. Within this paper, specific ion sources utilized at accelerator laboratories shall be reviewed along with the physics of surface and volume H{sup -} production in regard to source emittance. Current research trends including aperture modeling, thermal modeling, surface conditioning, and laser diagnostics will also be discussed.

  18. Schema bias in source monitoring varies with encoding conditions: support for a probability-matching account.

    Kuhlmann, Beatrice G; Vaterrodt, Bianca; Bayen, Ute J

    2012-09-01

    Two experiments examined reliance on schematic knowledge in source monitoring. Based on a probability-matching account of source guessing, a schema bias will only emerge if participants do not have a representation of the source-item contingency in the study list, or if the perceived contingency is consistent with schematic expectations. Thus, the account predicts that encoding conditions that affect contingency detection also affect schema bias. In Experiment 1, the schema bias commonly found when schematic information about the sources is not provided before encoding was diminished by an intentional source-memory instruction. In Experiment 2, the depth of processing of schema-consistent and schema-inconsistent source-item pairings was manipulated. Participants consequently overestimated the occurrence of the pairing type they processed in a deep manner, and their source guessing reflected this biased contingency perception. Results support the probability-matching account of source guessing. PsycINFO Database Record (c) 2012 APA, all rights reserved.

  1. Aging, source memory, and the experience of "remembering".

    Science.gov (United States)

    Kuhlmann, Beatrice G; Boywitt, C Dennis

    2016-07-01

    In a previous study, we found source memory for perceptual features to differentiate between younger but not older adults' reports of recollective ("remember"; R) and "know" (K) experiences. In two experiments with younger (17-30 years) and older (64-81 years) participants, we examined whether memory for meaningful speaker sources would accompany older adults' recollective experience. Indeed, memory for male and female speakers (but not partial memory for gender; Experiment 1) as well as bound memory for speakers and their facial expressions (Experiment 2) distinguished between both younger and older adults' RK reports. Thus, memory for some sources forms a common basis for younger and older adults' retrieval experience. Nonetheless, older adults still showed lower objective source memory and lower subjective source-attribution confidence than younger adults when reporting recollective experiences, suggesting that source memory is less relevant to their retrieval experience than for younger adults.

  2. Cassava Market Participation Decisions of Producing Households in Africa

    Directory of Open Access Journals (Sweden)

    Enete, AA.

    2009-01-01

    Full Text Available Cassava is a basic staple and a major source of farm income for the people of sub-Saharan Africa. Efficiency in cassava marketing therefore becomes a very important determinant of both consumer's living cost and producer's income. At the farmer's level, which is the beginning of the marketing chain, food must produced in reasonable quantity to attract enough market participants that will make for efficient distribution. The use of food price policy to stimulate short-run marketed surplus of producing households has often been questioned. This is because some households are deficit producers who purchase crops they also produce. Increasing producer prices will therefore have adverse distributional effects on food buying, while bypassing autarkic households. An alternative would therefore be to find non-price strategic variables that motivate farm households to participate in commodity markets. This is the objective of this paper. The paper is based on primary data collected within the framework by the collaborative study of cassava in Africa (COSCA. Good market access conditions, improved market information especially on prices, the production of granules instead of dried roots or pastes increased market participation for sellers, while rising grain prices, younger and less educated heads of households encouraged participation for buyers.

    Many planetary scientists consider involvement in a robotic spacecraft mission the highlight of their career. We have searched for names of science team members and determined the percentage of women on each team. We have limited the lists to members working at US institutions at the time of selection. We also determined the year each team was selected. The gender of each team member was limited to male and female and based on gender expression. In some cases one of the authors knew the team member and what pronouns they use. In other cases, we based our determinations on the team member's name or photo (obtained via a google search, including institution). Our initial analysis considered 22 NASA planetary science missions over a period of 41 years and only considered NASA-selected PI and Co-Is and not participating scientists, postdocs, or graduate students. We found that there has been a dramatic increase in participation of women on spacecraft science teams since 1974, from 0-2% in the 1970s - 1980s to an average of 14% 2000-present. This, however, is still lower than the recent percentage of women in planetary science, which 3 different surveys found to be ~25%. Here we will present our latest results, which include consideration of participating scientists. As in the case of PIs and Co-Is, we consider only participating scientists working at US institutions at the time of their selection.

    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.

    To identify key data sources of health information and describe their availability in countries of the World Health Organization (WHO) African Region. An analytical review on the availability and quality of health information data sources in countries; from experience, observations, literature and contributions from countries. Forty-six Member States of the WHO African Region. No participants. The state of data sources, including censuses, surveys, vital registration and health care facility-based sources. In almost all countries of the Region, there is a heavy reliance on household surveys for most indicators, with more than 121 household surveys having been conducted in the Region since 2000. Few countries have civil registration systems that permit adequate and regular tracking of mortality and causes of death. Demographic surveillance sites function in several countries, but the data generated are not integrated into the national health information system because of concerns about representativeness. Health management information systems generate considerable data, but the information is rarely used because of concerns about bias, quality and timeliness. To date, 43 countries in the Region have initiated Integrated Disease Surveillance and Response. A multitude of data sources are used to track progress towards health-related goals in the Region, with heavy reliance on household surveys for most indicators. Countries need to develop comprehensive national plans for health information that address the full range of data needs and data sources and that include provision for building national capacities for data generation, analysis, dissemination and use. © The Royal Society of Medicine.

    The concept of "participation" and the demand for the use of "participative methods" in human, healthcare, nursing and gerontological research as well as the corresponding fields of practice are in great demand; however, the targets and organization of "participation" are not always sufficiently explicated. The working group on critical gerontology of the German Society of Gerontology and Geriatrics uses this phenomenon as an opportunity for positioning and develops a catalogue of criteria for reflection and assessment of participation of elderly people in science and practice, which can also be considered a stimulus for further discussions.

    Full Text Available The purposes of this study were to identify the cognitive status of cancer survivors, determine the effect of cognitive status on function and participation in daily activities, and explore how cancer survivors perceive changes in their cognition. The study used a quantitative nonexperimental cross-sectional design. The participants included 35 cancer survivors from two different sites. Instruments included the Montreal Cognitive Assessment (MoCA and the Reintegration to Normal Index-Postal Version (RNLI-P in the measurement of cognitive impairment and functional performance respectively. Data were also collected with a supplemental questionnaire to explore participants’ perspectives on their cognitive difficulties and current function. The participant scores on the MoCA indicated cognitive impairment (μ= 25 and their scores on the RNLI-P demonstrated subpar reintegration (μ=9.64. Twenty-one participants answered the supplemental questionnaire. In content analysis of questionnaire responses, 17/21 participants reported some level of cognitive change related to cancer and cancer treatment. Data from an open-ended question were organized into four categories: decreased participation, more selective in activities, balance in activities, and cognitive changes. Study results indicate a large percentage of cancer survivors demonstrate mild cognitive impairment as well as changes in participation in instrumental activities of daily living.

    The relationship of attributed source (commercial or nonprofit) and credibility of exercise advertisements to explicit and implicit exercise-related attitudes and intentions was examined. Male and female participants (N = 227) were randomly assigned to watch health or appearance-related advertisements and then completed an implicit attitudes task and questionnaires. Health advertisements and those attributed to a nonprofit source were rated more credible. Appearance condition participants who attributed the advertisement to a nonprofit source also rated the advertisement as more credible. Participants who rated a commercial advertisement as credible reported higher implicit instrumental attitudes. Implications for exercise promotion are discussed.

    To examine factors associated with social participation and their relationship with self-perceived well-being in older adults. This study was based on data obtained from the National Socioeconomic Characterization (CASEN) Survey conducted in Chile, in 2011, on a probability sample of households. We examined information of 31,428 older adults living in these households. Descriptive and explanatory analyses were performed using linear and multivariate logistic regression models. We assessed the respondents' participation in different types of associations: egotropic, sociotropic, and religious. Social participation increased with advancing age and then declined after the age of 80. The main finding of this study was that family social capital is a major determinant of social participation of older adults. Their involvement was associated with high levels of self-perceived subjective well-being. We identified four settings as sources of social participation: home-based; rural community-based; social policy programs; and religious. Older adults were significantly more likely to participate when other members of the household were also involved in social activities evidencing an intergenerational transmission of social participation. Rural communities, especially territorial associations, were the most favorable setting for participation. There has been a steady increase in the rates of involvement of older adults in social groups in Chile, especially after retirement. Religiosity remains a major determinant of associativism. The proportion of participation was higher among older women than men but these proportions equaled after the age of 80. Self-perceived subjective well-being is not only dependent upon objective factors such as health and income, but is also dependent upon active participation in social life, measured as participation in associations, though its effects are moderate.

    Bearing in mind the importance of the informed consent, flaws in this process may be a barrier to participants' recruitment. Our objective was to determine the relationship between the degree of comprehension of the informed consent document plus the importance given to individual elements by potential participants of a hypothetical trial and their willingness to participate in such trials. We performed an Online Survey simulating an emergency department trial recruitment, posteriorly evaluating participants' ratings of importance and self-assessed comprehension of specific topics of the informed consent document. Only 10% of the sample read the entire document. Some specific topics were associated with willingness to participate in the hypothetical trial, but simple composite additive scores of comprehension and importance were not. We concluded that participants in general do not read the entire informed consent document and that importance given to specific topics may influence willingness to participate.

  15. A model of patient participation with chronic disease in nursing care

    Full Text Available Introduction: Chronic diseases are one of the greatest challenges that health systems facing with them today. Recently, patient participation is considered as a key element in chronic care models. However, there are few studies about participation of patients with chronic disease in caring activities. The aim of this study was to identify the factors, which are relevant to patient participation and the nature of participation in caring activities. Material and Methods: A qualitative approach with a basic theory method was used in this study. 22 persons including 9 patients, 8 nurses, and 5 family members were recruited using purposeful and theoretical sampling in three hospitals affiliated with Iran University of Medical Sciences. Data were collected with semi-structured interview and participant observation. Constant comparison was used for data analysis. Results: Findings of this study indicated that participation of patients with chronic disease in nursing care is a dynamic and interactive concept that occurs between nurse, patient and family member in a care-servicing system. The core theme of this study was "convergence of caring agents" that included four categories: adhering, involving, sharing and true participation. Conclusion: This study suggests a pyramid model for explaining patient participation. Participation occurs in different levels, which depends on the factors related to caring agents.

    I Review some of the salient accomplishments of X-rap studies of compact objects. Progress in this field has closely followed the improvement of observational methods, particularly in angular resolution and duration of exposure. Luminous compact X-ray sources are accreting neutron stars or black holes. Accreting neutron stars may have characteristic temporal signatures, but the only way to establish that an X-ray source is a black hole is to measure its mass. A rough phenomenological theory is succesful, but the transport of angular momentum in accretion flows is not onderstood. A number of interesting complications have been observed, including precessing accretion discs, X-ray bursts, and the acceleration of jets in SS433. Many puzzles remain unsolved, including the excitation of disc precession, the nature of the enigmatic A- and gamma-ray source Cyg X-3, the mechanism by which slowly spinning accreting neutron stars lose angular momentum, and the superabundance of X-ray sources in globular clusters. 41 refs.; 5 figs

    Participating in the social and civic life of communities is protectively associated with the onset and course of physical and mental disorders, and is considered important in achieving health promotion goals. Despite its importance in health research, there is no systematically developed measure of community participation. Our aim was to undertake the preliminary development of a community participation questionnaire, including validating it against an external reference, general psychological distress. Participants were 963 randomly selected community members, aged 19-97, from coastal New South Wales, Australia, who completed an anonymous postal survey. There were 14 types of community participation, most of which were characterised by personal involvement, initiative and effort. Frequency of participation varied across types and between women and men. Based on multiple linear regression analyses, controlling for socio-demographic factors, nine types of participation were independently and significantly associated with general psychological distress. Unexpectedly, for two of these, "expressing opinions publicly" and "political protest", higher levels of participation were associated with higher levels of distress. The other seven were: contact with immediate household, extended family, friends, and neighbours; participating in organised community activities; taking an active interest in current affairs; and religious observance. We called these the "Big 7". Higher levels of participation in the Big 7 were associated with lower levels of distress. Participating in an increasing number of the Big 7 types of participation was strongly associated in linear fashion with decreasing distress.

    As a means of promoting safety in the use of radiation sources, as well as encouraging consistency in regulatory control, the IAEA has from time to time organized training courses with the co-operation of Member State governments and organizations, to inform individuals from developing countries with appropriate responsibilities on the provisions for the safe use and regulation of radiation sources. Three such courses on the safe use of radiation sources have been held in both the USA, with the co-operation of the United States Government, and in Dublin, Ireland, with the co-operation of the Irish Government. The Training Course on the Safe Use and Regulation of Radiation Sources has been successfully given to over 77 participants from over 30 countries during the last years. The course is aimed at providing a basis of radiation protection knowledge in all aspects of the uses of radiation and of radiation sources that are used today. It is the intention of this course to provide a systematic enhancement of radioisotope safety in countries with developing radiological programmes through a core group of national authorities. The IAEA's training programmes provide an excellent opportunity for direct contact with lecturers that have extensive experience in resolving issues faced by developing countries and in providing guidance documents useful in addressing their problems. This document uses this collective experience and provides valuable technical information regarding the safety aspects of the uses not only of sealed and unsealed sources of radiation, but also for those machines that produce ionizing radiation. The first of these training courses, 'Safety and Regulation of Unsealed Sources' was held in Dublin, Ireland, June through July 1989 with the co-operation of the Nuclear Energy Board and Trinity College. This was an interregional training course, the participants came from all over the world. The second and third interregional courses, 'Safety and Regulation

    The aim of the Postgraduate Educational Course in Radiation Protection and the Safety of Radiation Sources is to meet the needs of professionals at graduate level, or the equivalent, for initial training to acquire a sound basis in radiation protection and the safety of radiation sources. The course also aims to provide the necessary basic tools for those who will become trainers in radiation protection and in the safe use of radiation sources in their countries. It is designed to provide both theoretical and practical training in the multidisciplinary scientific and/or technical bases of international recommendations and standards on radiation protection and their implementation. The participants should have had a formal education to a level equivalent to a university degree in the physical, chemical or life sciences or engineering and should have been selected to work in the field of radiation protection and the safe use of radiation sources in their countries. The present revision of the Standard Syllabus takes into account the requirements of the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS), IAEA Safety Series No. 115 (1996) and recommendations of related Safety Guides, as well as experience gained from the Postgraduate Educational Course on Radiation Protection and Safety of Radiation Sources held in several regions in recent years. The general aim of the course, as mentioned, is the same. Some of the improvements in the present version are as follows: The learning objective of each part is specified. The prerequisites for each part are specified. The structure of the syllabus has been changed: the parts on Principles of Radiation Protection and on Regulatory Control were moved ahead of Dose Assessment and after Biological Effects of Radiation. The part on the interface with nuclear safety was dropped and a module on radiation protection in nuclear power plants has been included. A

  5. Volunteered Geographic Information System Design: Project and Participation Guidelines

    José-Pablo Gómez-Barrón

    2016-07-01

    Full Text Available This article sets forth the early phases of a methodological proposal for designing and developing Volunteered Geographic Information (VGI initiatives based on a system perspective analysis in which the components depend and interact dynamically among each other. First, it focuses on those characteristics of VGI projects that present different goals and modes of organization, while using a crowdsourcing strategy to manage participants and contributions. Next, a tool is developed in order to design the central crowdsourced processing unit that is best suited for a specific project definition, associating it with a trend towards crowd-based or community-driven approaches. The design is structured around the characterization of different ways of participating, and the task cognitive demand of working on geo-information management, spatial problem solving and ideation, or knowledge acquisition. Then, the crowdsourcing process design helps to identify what kind of participants are needed and outline subsequent engagement strategies. This is based on an analysis of differences among volunteers’ participatory behaviors and the associated set of factors motivating them to contribute, whether on a crowd or community-sourced basis. From a VGI system perspective, this paper presents a set of guidelines and methodological steps in order to align project goals, processes and volunteers and thus successfully attract participation. This methodology helps establish the initial requirements for a VGI system, and, in its current state, it mainly focuses on two components of the system: project and participants.

  6. Receiving Assistance and Local Food System Participation

    2017-02-01

    Full Text Available A body of literature has noted that local food systems (LFSs may not involve active participation by individuals with lower incomes. This is, in part, a function of racial and class hegemony, as well as physical and financial accessibility of LFSs. LFS institutions, such as farmers’ markets, have been working to facilitate receipt of food assistance programs, such as the Supplemental Nutrition Assistance Program (SNAP. Charitable assistance programs, such as food banks, have also been actively working to engage in LFSs, for example, by making local foods available. However, little research has explored the role that receiving public or charitable assistance can play in influencing LFS participation. In this article, I utilize quantitative and qualitative data collected from across the state of Ohio to examine the relationship between receiving assistance and LFS participation for women, who remain predominately responsible for food provisioning in the U.S., including among those who participate in LFSs. Quantitative results suggest that receiving assistance can increase participation in LFSs. Qualitative data provides more nuanced information about the importance of food assistance for women who want to participate in LFSs, and suggest that it is essential that food cooperatives and farmers’ markets are equipped to receive food assistance programs, such as SNAP, in order for women with lower incomes to participate in LFSs.

    This workshop was carried out under the auspices of the Lawrence Berkeley National Laboratory Pulsed Spallation Source activity and its Pulsed Spallation Source Committee (PSSC). One of our activities has been the sponsorship of workshops related to neutron production by pulsed sources. At the Crystal City PSSC meeting a decision was made to hold a workshop on the instrumentation opportunities at a long-pulse spallation source (LPSS). The enclosed material represents the results of deliberations of the three working groups into which the participants were divided, covering elastic scattering, inelastic scattering and fundamental physics, as well as contributions from individual participants. We hope that the material in this report will be useful to the neutron scattering community as it develops a road-map for future neutron sources. The workshop was held at LBNL in mid-April with about sixty very dedicated participants from the US and abroad. This report presents the charge for the workshop: Based on the bench mark source parameters provided by Gary Russell, determine how a suite of spectrometers in each of the three working group's area of expertise would perform at an LPSS and compare this performance with that of similar spectrometers at a continuous source or a short-pulse source. Identify and discuss modifications to these spectrometers that would enhance their performance at an LPSS. Identify any uncertainties in the analysis of spectrometer performance that require further research. Describe what R ampersand D is needed to resolve these issues. Discuss how the performance of instruments would be affected by changes in source parameters such as repetition rate, proton pulse length, and the characteristic time of pulse tails. Identify beneficial changes that could become goals for target/moderator designers. Identify novel methods that might be applied at an LPSS.

    The US Department of Energy (DOE), Office of Civilian Radioactive Waste Management (OCRWM) has assigned components of its Waste Transportation Program to three of the DOE Operations offices. The DOE Oak Ridge Operations Office (ORO) is responsible for the transportation operations design, development, acquisition, testing, implementation, and program management, including the equipment, facilities, and services of the transportation system. Within ORO, the OCRWM transportation component is assigned to the Transportation Operations Project Office (TOPO). The specific activities involved in the ORO/TOPO include procurement, operational testing, inspection, logistics, interfaces, maintenance, management and improvements, and system operation. Oak Ridge Associated Universities (ORAU) has developed (and will maintain and enhance) a data base of sources of transportation expertise in selected technical areas for ORO. The data base includes individuals and organizations who have indicated that they have capabilities and interest in assisting ORO in the design, development, implementation, and management of the OCRWM transportation system. This assistance might be in the form of consulting or subcontract work and/or participation in peer review panels, technical evaluation committees, workshops, advisory groups, etc. This initial project was completed in the four month period of January 30, 1987 through May 31, 1987

    A group of physicists at TRIUMF have been meeting regularly to discuss options for involvement in experiments that relate closely to the physics that would be undertaken at the KAON Factory. At a meeting held to discuss possibilities for work at KEK in the light of the new facilities that are under construction or proposed as part of the JHP, the topics considered ranged from the ion source to kaon beams. They included measurements of kaon-nucleon elastic and inelastic scattering in the 1600 to 2000 MeV range; transport of polarized proton beams through synchrotrons; the development of laser pumped polarized ion sources and volume cusp H - sources; studies of the problems that high intensity beams will present for the maintenance of H - stripping foils; collaboration on radioactive beam facilities; production of hypernuclei; low energy kaon scattering; and new types of detectors

  12. Choice and Participation of Career by STEM Professionals with Sensory and Orthopedic Disabilities and the Roles of Assistive Technologies

    Science.gov (United States)

    Pacheco, Heather A.

    This is a qualitative study about sources of self-efficacy and roles of assistive technologies (AT) associated with the science, technology, engineering and mathematics (STEM) choice and participation of STEM professionals and graduate students with sensory and orthopedic disabilities. People with disabilities are underrepresented in STEM, which can be traced back along the STEM pipeline to early undergraduate participation in STEM. Little research exists, however, about pathways and factors associated with successful STEM participation for people with disabilities at any point along their trajectories. Eighteen STEM professionals and graduate students with sensory and orthopedic disabilities were interviewed for this study. Sources of self-efficacy were sought from interview transcripts, as were emergent themes associated with the types, uses and roles of AT. Findings suggest that people with sensory and orthopedic disabilities weigh sources of self-efficacy differently from white males without disabilities in STEM and more like other underrepresented minorities in STEM. Social persuasions were most frequently reported and in far more detail than other sources, suggesting that this source may be most impactful in the development of self-efficacy beliefs for this group. Additionally, findings indicate that AT is critical to the successful participation of people with sensory and orthopedic disabilities in STEM at all points along their STEM pathways. Barriers center around issues of access to full engagement in mainstream STEM classrooms and out of school opportunities as well as the impact of ill-informed perceptions about the capabilities of people with disabilities held by parents, teachers and college faculty who can act as gatekeepers along STEM pathways. Gaps in disability specialists' knowledge about STEM-specific assistive technologies, especially at the college level, are also problematic. The prevalence of mainstream public school attendance reported by

    The CSCview data mining interface is available for browsing the Chandra Source Catalog (CSC) and downloading tables of quality-assured source properties and data products. Once the desired source properties and search criteria are entered into the CSCview query form, the resulting source matches are returned in a table along with the values of the requested source properties for each source. (The catalog can be searched on any source property, not just position.) At this point, the table of search results may be saved to a text file, and the available data products for each source may be downloaded. CSCview save files are output in RDB-like and VOTable format. The available CSC data products include event files, spectra, lightcurves, and images, all of which are processed with the CIAO software. CSC data may also be accessed non-interactively with Unix command-line tools such as cURL and Wget, using ADQL 2.0 query syntax. In fact, CSCview features a separate ADQL query form for those who wish to specify this type of query within the GUI. Several interfaces are available for learning if a source is included in the catalog (in addition to CSCview): 1) the CSC interface to Sky in Google Earth shows the footprint of each Chandra observation on the sky, along with the CSC footprint for comparison (CSC source properties are also accessible when a source within a Chandra field-of-view is clicked); 2) the CSC Limiting Sensitivity online tool indicates if a source at an input celestial location was too faint for detection; 3) an IVOA Simple Cone Search interface locates all CSC sources within a specified radius of an R.A. and Dec.; and 4) the CSC-SDSS cross-match service returns the list of sources common to the CSC and SDSS, either all such sources or a subset based on search criteria.

    In March 2002, an initial attempt was made to decrease breast cancer mortality by the Japan Society of Breast Health, by means of encouraging participation in sports. This was followed by other similar events. The present study was designed to examine whether these kinds of sport-associated events are actually effective for increasing the screening participation rate. We hoped that the results would reveal practical ways of organizing such programs. One of these activities, the All Japan Women's Tennis Players' League, has called for amateur players to participate in an annual meeting of the Pink Ribbon Ladies' Tennis Tournament since 2003. A survey of their knowledge about breast cancer and their will to participate in breast cancer screening has been carried out annually in 2003, 2004 and 2005, by asking the participants to respond to our questionnaires. As a result, the number of participants has increased: from 7,201 women in 2003, to 7,846 in 2004 and to 8,572 in 2005. The questionnaires included items about participation in breast cancer screening, performance of self-examination, and participation in mammography screening. The participation rate increased year by year. The participation rate at mammography screening was 21% in 2003, and this increased to 26% in 2005. Thus this kind of sports event appears to promote knowledge about breast cancer screening and to increase the participation rate. On the other hand, it was found that the rate of self-examination decreased from 53% to 22%. Therefore problems that need to be addressed in the future include not only increasing women's motivation to undergo screening, but also the selection of appropriate screening methods, their combination, and distribution of accurate information.

    2005-01-01

    For decades the international standards and requirements postulate severe control over all lifecycle phases of radioactive sources in order to prevent risks associated with exposure of people and the environment. Despite this fact the orphan sources became a serious problem as a consequence of enlargement of economic transactions in many countries in Europe as well as in the world. The countries as well as international organisations, aware of this emerging problem, are trying to gain control over orphan sources using different approaches. These approaches include control over sources before they could become orphan sources. In addition, countries are also developing action plans in case that an orphan source could be found. The problems related to orphan sources in Slovenia is discussed based on the case studies from the last years. While in the nineties of the last century just a few cases of orphan sources were identified their number has increased substantially since 2003. The paper discusses the general reasons for the phenomena of orphan sources as well as the experience related to regaining control over orphan sources. (author)

    This paper discusses how New York's approach to developing a new low-level radioactive waste disposal facility demonstrates a commitment to responsibility for waste generated within its borders. There is a strong, legislated commitment to meeting federal milestones and starting from scratch to select a suitable site and disposal method. Equally strong is the state's commitment to meaningful public participation. A statewide program is underway, including public information and education and interactive techniques. The public participation program is fully integrated with the technical and policy activities of the New York State Low-Level Radioactive Waste Siting Commission at all levels. The program is designed to progressively tailor techniques and coverage to the steps in site and method selection, and will focus most intensively on the communities where four sites are selected for full characterization

    Emergency contraception (EC) can prevent pregnancy for up to 5 days after unprotected sex. Although EC has become increasingly available, little is known about perceptions of young adults regarding access to EC or whether information sources about EC relate to perceived access among young adults. Over a 1-week period in November 2013, a self-report survey was administered to 352 college students (67% women) at the student union of a large, public university in the southeastern United States. The survey assessed three aspects of EC: perceived access, information sources, and prior use. Twenty-one percent of participants had used EC. Participants reported relatively high perceptions of access to EC, with females reporting higher perceptions of access than males. Prior to the study, 7.4% of students had never heard of EC; the remaining students had heard of EC from an average of four sources. Among women, hearing of EC from media, interpersonal, or health education sources was significantly associated with greater perceived access (ps sources were associated with perceived access (ps > .10). Future EC awareness efforts for women should leverage all three of these sources, while future research should examine specific sources to focus on the content, quality, and frequency of messages.

    This paper describes the participation of the IPEN in the International Atomic Energy Agency (IAEA) Coordinated Research Projects(CRP) on Analytical and Experimental Benchmark Analysis on ADS and Low Enriched Uranium Fuel Utilization in ADS. The first CRP has as specific objective to improve the present understanding of the coupling of an external neutron source [e.g. a spallation source in the case of the accelerator driven system (ADS)] with a multiplicative sub-critical core, and the second CRP, or collaborative work, the utilization of LEU in existing or planned ADS facilities. IPEN participate in both CRP through a research contract (13388), and although there are several benchmarks defined in both CRP, presently IPEN is participating in the activities related with reactor physics benchmark of the Yalina Booster facility in Belarus, in the analytical and numerical benchmarking of methods and codes for ADS kinetics, and in the ADS target calculations. Besides, since there are plans to introduce a compact neutron generator in a sub critical core of the IPEN-MB-01 facility, a benchmark of a simulation of such project has been proposed in the LEU-ADS CRP. The paper will review the CRPs with details on the activities in which IPEN is participating. (author)

  4. The ʽDiverse Economies’ of Participation

    Directory of Open Access Journals (Sweden)

    2014-08-01

    Full Text Available This article begins to construct a theory of participation in architecture, urban design and urban planning as a range of practices undertaken across a landscape of economies that largely exists outside of the capitalist economy. These practices themselves overlap in terms of their material forms, bodily and mental activities with the practices undertaken by labour employed to produce the built environment within the capitalist marketplace.With respect to participation, our aim in articulating practices is to move away from a discussion of levels of participation and legitimacy within individual projects and towards an understanding of the organising, productive and reproductive work that is done in participating in the production of the built environment as part of an ongoing process of social change. They proliferate through multiple instances of performance and those who undertake them act as carriers of these practices, including forms of knowhow, understanding, motivational and emotional knowledge, creating resources through these acts of performance.The article contends that participatory practices are liable to be exploited re-presented or co-opted as commodified resources and this fragility limits the socially transformative potential of participation. Drawing on J.K Gibson-Graham’s conception of ‘diverse economies’, an alternative representation is developed to recognize the landscape of practices constructing alternative economic systems, and exploring means and methods of resistance to co-option or enclosure.

    To examine participation-preference congruence, regional differences in participation-preference congruence, and predictors of whether children with cerebral palsy participate in preferred activities. The sample (n=236) included 148 males and 88 females aged 10 to 13 years, living in Victoria, Australia (n=110), Ontario (n=80), or Quebec (n=46), Canada. Ninety-nine (41.9%) were classed at Gross Motor Function Classification System (GMFCS) level I; 89 (37.7%) at GMFCS level II/III; and 48 (20.3%) at GMFCS level IV/V. Participants completed the Children's Assessment of Participation and Enjoyment and Preferences for Activity of Children questionnaires. Regional comparisons were performed using one-way analyses of variance and factors influencing participation-preference congruence were explored using multiple linear regression. The proportion of children doing non-preferred activities in each activity type was generally low (2-17%), with only one regional difference. Higher proportions were not doing preferred active physical (range 23.2-29.1% across regions), skill-based (range 21.7-27.9% across regions), and social activities (range 12.8-14.5% across regions). GMFCS level was the most important predictor associated with not doing preferred activities. Children with cerebral palsy did not always participate in preferred active physical and skill-based activities. Understanding discrepancies between preferences and actual involvement may allow families and rehabilitation professionals to address participation barriers. © 2016 Mac Keith Press.

    Full Text Available Introduction. Physical activity is critical to effective rehabilitation in people with disabilities and, consequently, is of high importance in their lives. However, participation of the disabled in physical activity, including tourism, is a much more complex issue than in the case in able-bodied individuals. Material and methods. This paper aims to fill the gap and familiarise the reader with barriers faced by the disabled who engage in tourism. The study group consisted of randomly selected 460 participants with certificates specifying the degree of their disability. The group included 55 (12% individuals with visual impairments, 203 (44.1% individuals with hearing impairments, and 202 (43.9% individuals with locomotor system disabilities. Results. The data derived from interviews made with people with physical dysfunctions, designed with a view to achieving the aims of the study, were used to develop logistic regression models. Conclusions. On average, the greatest and smallest numbers of barriers were reported by individuals with severe disabilities and those who had large families, respectively. Younger disabled people most often complained about the equipment barriers to participation in tourism. Older respondents were mostly challenged with social barriers. Of all the determinants analysed in the study, the perception of barriers to participation in tourism most often depended on the subjects’ degree of disability.

    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.

    Rural emergency departments (EDs) generally have limited access to continuing education and are typically staffed by clinicians without pediatric emergency specialty training. Emergency care of children is complex and the majority of children receive emergency care in non-pediatric tertiary care centers. In recent decades, there has been a call to action to improve quality and safety in the emergency care of children. Of the one million ED visits by children in Ontario in 2005-2006, one in three visited more than once in a year and one in 15 returned to the ED within 72 hours of the index visit. This study explored factors influencing rural and urban ED clinicians' participation in a Web-based knowledge exchange intervention that focused on best practice knowledge about pediatric emergency care. The following questions guided the study: (i) What are the individual, context of practice or knowledge factors which impact a clinician's decision to participate in a Web-based knowledge exchange intervention?; (ii) What are clinicians' perceptions of organizational expectations regarding knowledge and information sources to be used in practice?; and (iii) What are the preferred knowledge sources of rural and urban emergency clinicians? A Web-based knowledge exchange intervention, the Pediatric Emergency Care Web Based Knowledge Exchange Project, for rural and urban ED clinicians was developed. The website contained 12 pediatric emergency practice learning modules with linked asynchronous discussion forums. The topics for the modules were determined through a needs assessment and the module content was developed by known experts in the field. A follow-up survey was sent to a convenience sample of 187 clinicians from nine rural and two urban Canadian EDs participating in the pediatric emergency Web-based knowledge exchange intervention study. The survey response rate was 56% (105/187). Participation in the knowledge exchange intervention was related to individual

    Full Text Available OBJECTIVE To examine factors associated with social participation and their relationship with self-perceived well-being in older adults. METHODS This study was based on data obtained from the National Socioeconomic Characterization (CASEN Survey conducted in Chile, in 2011, on a probability sample of households. We examined information of 31,428 older adults living in these households. Descriptive and explanatory analyses were performed using linear and multivariate logistic regression models. We assessed the respondents’ participation in different types of associations: egotropic, sociotropic, and religious. RESULTS Social participation increased with advancing age and then declined after the age of 80. The main finding of this study was that family social capital is a major determinant of social participation of older adults. Their involvement was associated with high levels of self-perceived subjective well-being. We identified four settings as sources of social participation: home-based; rural community-based; social policy programs; and religious. Older adults were significantly more likely to participate when other members of the household were also involved in social activities evidencing an intergenerational transmission of social participation. Rural communities, especially territorial associations, were the most favorable setting for participation. There has been a steady increase in the rates of involvement of older adults in social groups in Chile, especially after retirement. Religiosity remains a major determinant of associativism. The proportion of participation was higher among older women than men but these proportions equaled after the age of 80. CONCLUSIONS Self-perceived subjective well-being is not only dependent upon objective factors such as health and income, but is also dependent upon active participation in social life, measured as participation in associations, though its effects are moderate.

  16. Securing radioactive sources through a proper management

    Mourao, Rogerio Pimenta

    2009-01-01

    The safety and security of radioactive sources have become a hot issue for the nuclear community in the last two decades. The Goiania accident in Brazil and the September 11th attack alerted governments and nuclear agencies around the world to the vulnerability of the thousands of disused radioactive sources ill-stored or misplaced in a myriad of ways, especially in countries with less developed infra-structure. Once the threat of environmental contamination or malevolent use of these sources became clear, the International Atomic Energy Agency and the American Government spawned initiatives to reduce this risk, basically stimulating the proper conditioning of the sources and, whenever possible, seeking their repatriation to the countries of origin. Since 1996 Brazil has been participating actively in this effort, having carried out hands-on operations to condition old radium sources in Latin American and Caribbean countries and also repatriated its own neutron sources to the United States. A new operation is presently being organized: the reconditioning of the high activity sources contained in teletherapy units stored in the country using a mobile hot cell developed in South Africa. Also an agreement is being negotiated between the US National Nuclear Security Agency and the Brazilian CNEN to repatriate hundreds of radioactive gauges presently stored at CNEN's source storage buildings.

    2010-01-01

    The dual process model assumes memory is based on recollection (retrieval with specific detail) or familiarity (retrieval without specific detail). A current debate is whether recollection is a threshold process or, like familiarity, is a continuous process. In the present study two continuous models and two threshold models of recollection were evaluated using receiver operating characteristic (ROC) analysis. These models included the continuous signal detection unequal variance model and the threshold dual process model. In the study phase of three experiments, objects were presented to the right or left of fixation. At test, participants made either remember-know responses or item confidence responses followed by source memory (spatial location) confidence ratings. Recollection-based ROCs were generated from source memory confidence ratings associated with "remember" responses (in Experiments 1-2) or the highest item confidence responses (in Experiment 3). Neither threshold model adequately fit any of the recollection-based ROCs. By contrast, one or both of the continuous models adequately fit all of the recollection-based ROCs. The present results indicate recollection and familiarity are both continuous processes.

    Full Text Available Fan activism lies at the intersection of cultural and political participation. The study of fan activism can inform our understanding of contemporary collective action more broadly. We suggest four key areas for analysis: the relationships between cultural and political participation; the tension between participation and resistance in the context of fan activism; affect and the role of content worlds in civic and political mobilization; and evaluation of the impacts of fan activism. By drawing on work across several disciplines including media studies and social movement literature, the analysis of fan activism through these lenses offers insights for theorizing contemporary cultures and modes of collective action.

    2014-01-01

    Background The functional food industry has experienced innovative and economic expansion, yet research into consumer perceptions of functional foods and their associated health claims is limited. Among consumers, older adults could benefit from functional foods due to age-related issues pertaining to food and health. The purpose of this research was to identify the need for information related to functional foods among older adults (≥60 years old) and to assess awareness and perceptions of health claims on functional food packages. Methods Community-dwelling older adults (n = 200) completed a researcher administered questionnaire designed to collect information about functional foods including current consumption, motivating factors for consumption, perceived need for information, sources of information for functional foods and awareness of health claims. Results Prevalence of functional food consumption among participants was 93.0%. Increased awareness and knowledge was the most commonly reported factor that would promote functional food consumption (85.5%) and 63.5% of participants wanted more information about functional foods with preferred sources being newspapers/magazines/books (68.5%) and food labels (66.1%). Participants were predominately (93.5%) aware of health claims on functional foods and those with more education were more likely to report being aware of health claims (p = 0.045). Conclusions Although functional food consumption among older adults in this sample is high, there is a need for further information regarding functional foods. These results inform stakeholders regarding the potential for information to influence functional food acceptance among older adult consumers. PMID:24886306

    Full Text Available Systemic sclerosis, or scleroderma, is a chronic and rare connective tissue disease with negative physical and psychological implications. Sources of emotional distress and the impact they have on the lives of people with scleroderma are not well understood.To gain an in-depth understanding of the emotional experiences and sources of emotional distress for women and men living with scleroderma through focus group discussions.Three semi-structured focus group discussions were conducted (two in English, one in French with a total of 22 people with scleroderma recruited through the Scleroderma Society of Ontario in Hamilton, Ontario and a scleroderma clinic in Montreal, Canada. Interviews were recorded, transcribed, and then coded for emerging themes using thematic inductive analysis.Core themes representing sources of emotional distress were identified, including: (a facing a new reality; (b the daily struggle of living with scleroderma; (c handling work, employment and general financial burden; (d changing family roles; (e social interactions; and (f navigating the health care system. Collectively, these themes refer to the stressful journey of living with scleroderma including the obstacles faced and the emotional experiences beginning prior to receiving a diagnosis and continuing throughout the participants' lives.Scleroderma was portrayed as being an unpredictable and overwhelming disease, resulting in many individuals experiencing multiple sources of emotional distress. Interventions and supportive resources need to be developed to help individuals with scleroderma and people close to them manage and cope with the emotional aspects of the disease.

    Based on social-learning and self-determination motivational theories, the purpose of this study was to determine the sources of motivation in youth and young adults with intellectual disability (ID) who participate in Special Olympics (SO) competitions and those of typically developed (TD) age- and activity-matched athletes. A convenience sample of 63 SO (25 females and 38 males) and 59 TD (16 females and 43 males) athletes was retrieved through communication with local club coaches. Three sub-groups of SO athletes were identified based on disability, including non specified intellectual disability (NSID=39), Down syndrome (DS=17), and Autism (Aut=7). Mean SO and TD athlete ages were 20.35 (SD=7) and 18.8 (SD=8), respectively. For analysis purposes four age groups were created (20 years). Participants completed the 13-item, two-factor Task and Ego Orientation in Sport Questionnaire (TEOSQ) and a 16-item four-factor abridged version of the Sport Motivation Scale (SMS). SO and TD athletes were active in swimming (54 and 48, respectively) and basketball (9 and 11, respectively). Groups with and without ID were compared by means of t-tests in the dichotomized variables gender and activity, as well as by 1-way ANOVA with Tukey HSD post hoc comparisons across disability and age groups. Gender distribution was the same in both groups. Participants with DS and NSID scored significantly higher than TD athletes in most motivational scales. Participants with ID increased their external motivation with increasing age, while a reversed pattern was observed in TD. In summary, significant differences between motivational patterns of SO athletes with ID and TD athletes can be observed. These differences should be considered when developing training and competition programs. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The aims of this study were to identify demographic and socio-economic predictors of non-participation in cervical screening in Denmark, and to evaluate the influence of health care use on screening participation. A population based register study was undertaken using data from the Central Population Register, the national Patobank, and Statistics Denmark. The study included women aged 25-54 years on 1st of January 2002, living in Denmark during the next 5 years, and without a history of total hysterectomy, N=1,052,447. Independent variables included age, civil status, nationality, level of education, and use of health care. Associations with non-participation in screening were determined with logistic regression. Main predictors of non-participation were limited or no contact with dental services (odds ratio (OR)=2.36), general practitioners (OR=1.75), and high age (OR=1.98). Other important factors for non-participation were primary school education only (OR=1.53), not being married (OR=1.49), and foreign nationality (OR=1.32). A 2-1.5-fold difference in non-participation in cervical screening in Denmark was found across various population sub-groups. Increased screening compliance among women with primary school education only, and limited or no use of primary health care services in general could potentially diminish the current social inequalities in cervical cancer incidence, and thus decrease the overall high incidence of this disease in Denmark.

  4. Increased intra-participant variability in children with autistic spectrum disorder: Evidence from single trial analyses of evoked EEG.

    Full Text Available Intra-participant variability in clinical conditions such as autistic spectrum disorder (ASD is an important indicator of pathophysiological processing. The data reported here illustrate that trial-by-trial variability can be reliably measured from EEG, and that intra-participant EEG variability is significantly greater in those with ASD than in neuro-typical matched controls. EEG recorded at the scalp is a linear mixture of activity arising from muscle artifacts and numerous concurrent brain processes. To minimise these additional sources of variability, EEG data were subjected to two different methods of spatial filtering. (i The data were decomposed using infomax Independent Component Analysis (ICA, a method of blind source separation which un-mixes the EEG signal into components with maximally independent time-courses, and (ii a surface Laplacian transform was performed (Current Source Density interpolation in order to reduce the effects of volume conduction. Data are presented from thirteen high functioning adolescents with ASD without co-morbid ADHD, and twelve neuro-typical age- IQ- and gender-matched controls. Comparison of variability between the ASD and neuro-typical groups indicated that intra-participant variability of P1 latency and P1 amplitude was greater in the participants with ASD, and inter-trial α-band phase coherence was lower in the participants with ASD. These data support the suggestion that individuals with ASD are less able to synchronise the activity of stimulus-related cell assemblies than neuro-typical individuals, and provide empirical evidence in support of theories of increased neural noise in ASD.

    Need and requirement for the intense neutron source for fusion materials study have been discussed for many years. Recently, international climate has been becoming gradually maturing to consider this problem more seriously because of the recognition of crucial importance of solving materials problems for fusion energy development. The present symposium was designed to discuss the problems associated with the intense neutron source for material irradiation studies which will have a potential for the National Institute for Fusion Science to become one of the important future research areas. The symposium comprises five sessions; first, the role of materials research in fusion development strategies was discussed followed by a brief summary of current IFMIF (International Fusion Materials Irradiation Facility) activity. Despite the pressing need for intense fusion neutron source, currently available neutron sources are reactor or accelerator based sources of which FFTF and LASREF were discussed. Then, various concepts of intense neutron source candidates were presented including ESNIT, which are currently under design by JAERI. In the fourth session, discussions were made on the study of materials with the intense neutron source from the viewpoint of materials scientists and engineers as the user of the facility. This is followed by discussions on the role of universities from the two stand points, namely, fusion irradiation studies and fusion materials development. Finally summary discussions were made by the participants, indicating important role fundamental studies in universities for the full utilization of irradiation data and the need of pure 14 MeV neutron source for fundamental studies together with the intense surrogate neutron sources.

    Many clinical trials rely on participant report to first learn about study events. It is therefore important to have current contact information and the ability to locate participants should information become outdated. The Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial (PLCO) and the Lung Screening Study (LSS) component of the National Lung Screening Trial, two large randomized cancer screening trials, enrolled almost 190,000 participants on whom annual contact was necessary. Ten screening centers participated in both trials. Centers developed methods to track participants and trace them when necessary. We describe the methods used to keep track of participants and trace them when lost, and the extent to which each method was used. Screening center coordinators were asked, using a self-administered paper questionnaire, to rate the extent to which specific tracking and tracing methods were used. Many methods were used by the screening centers, including telephone calls, mail, and internet searches. The most extensively used methods involved telephoning the participant on his or her home or cell phone, or telephoning a person identified by the participant as someone who would know about the participant's whereabouts. Internet searches were used extensively as well; these included searches on names, reverse-lookup searches (on addresses or telephone numbers) and searches of the Social Security Death Index. Over time, the percentage of participants requiring tracing decreased. Telephone communication and internet services were useful in keeping track of PLCO and LSS participants and tracing them when contact information was no longer valid. Published by Elsevier Inc.

    An electrospray ion (ESI) source and method capable of ionizing an analyte molecule without oxidizing or reducing the analyte of interest. The ESI source can include an emitter having a liquid conduit, a working electrode having a liquid contacting surface, a spray tip, a secondary working electrode, and a charge storage coating covering partially or fully the liquid contacting surface of the working electrode. The liquid conduit, the working electrode and the secondary working electrode can be in liquid communication. The electrospray ion source can also include a counter electrode proximate to, but separated from, said spray tip. The electrospray ion source can also include a power system for applying a voltage difference between the working electrodes and a counter-electrode. The power system can deliver pulsed voltage changes to the working electrodes during operation of said electrospray ion source to minimize the surface potential of the charge storage coating.

    Gestational diabetes mellitus (GDM) is a risk factor for the development of type 2 diabetes. Lifestyle intervention can prevent progression to type 2 diabetes in high risk populations. We designed a randomised controlled trial (RCT) to evaluate the effectiveness of an established lifestyle intervention compared to standard care for delaying diabetes onset in European women with recent GDM. Recruitment into the RCT was more challenging than anticipated with only 89 of 410 (22%) women agreeing to participate. This paper identifies factors that could enhance participation of the target population in future interventions. We hypothesised that women who agreed to participate would have higher diabetes risk profiles than those who declined, and secondly that it would be possible to predict participation on the bases of those risk factors. To test our hypothesis, we identified the subset of women for whom we had comprehensive data on diabetes risks factors 3-5 years following GDM, reducing the sample to 43 participants and 73 decliners. We considered established diabetes risk factors: smoking, daily fruit and vegetable intake, participation in exercise, family history of diabetes, glucose values and BMI scores on post-partum re-screens, use of insulin during pregnancy, and age at delivery. We also analysed narrative data from 156 decliners to further understand barriers to and facilitators of participation. Two factors differentiated participants and decliners: age at delivery (with women older than 34 years being more likely to participate) and insulin use during pregnancy (with women requiring the use of insulin in pregnancy less likely to participate). Binary logistic regression confirmed that insulin use negatively affected the odds of participation. The most significant barriers to participation included the accessibility, affordability and practicality of the intervention. Women with recent GDM face multiple barriers to lifestyle change.

    2002-01-01

    Existing spallation neutron source upgrades, planned spallation neutron sources, and high-energy accelerators for particle physics place demanding requirements on the Hsources. These requirements ask for increased beam currents and duty factor (df) while generally maintaining state-of-the art H' source emittance. A variety of H sources are being developed to address these challenges. These include volume sources with and without the addition of cesium for enhanced He production, increased df cesiated H' Penning and magnetron sources, and cesiated surface converter H- sources. Research on surface films of tantalum metal for enhanced volume H- production is also being studied. Innovative plasma production techniques to address the longer df requirement without sacrificing H- source reliability and liktime will be reviewed. The physical bases, the goals, and perceived challenges will be discussed.

    1985-01-01

    The m = 1 Helicity Source, formerly called the Kinked Z-pinch, was developed as part of the Electrode Studies program at Los Alamos. The Electrode Studies program was initiated to study the control of electrode erosion in long discharge duration spheromak sources. Erosion control is necessary to reduce plasma impurities and to obtain adequate electrode lifetimes. The first task of the Electrode Studies program is to determine, from among a variety of configurations including the coaxial one, a helicity source geometry with good prospects for erosion control. The more efficient the helicity source the easier it will be to control erosion, but the source most also be easy to diagnose and modify if it is to be a useful test bed. The various erosion control techniques which have been proposed will require extensive experimentation to evaluate and optimize. Proposed techniques include, using refractory metals, profiling of the electrodes and magnetic fields, and various gas injection schemes including porous electrodes. It is considered necessary to do these experiments on an optimized helicity source so that the electrode geometries and plasma properties will be relevant. Therefore the present Electrode Studies program is aimed at developing an improved helicity source design

  20. Negative effects of item repetition on source memory.

    2012-08-01

    In the present study, we explored how item repetition affects source memory for new item-feature associations (picture-location or picture-color). We presented line drawings varying numbers of times in Phase 1. In Phase 2, each drawing was presented once with a critical new feature. In Phase 3, we tested memory for the new source feature of each item from Phase 2. Experiments 1 and 2 demonstrated and replicated the negative effects of item repetition on incidental source memory. Prior item repetition also had a negative effect on source memory when different source dimensions were used in Phases 1 and 2 (Experiment 3) and when participants were explicitly instructed to learn source information in Phase 2 (Experiments 4 and 5). Importantly, when the order between Phases 1 and 2 was reversed, such that item repetition occurred after the encoding of critical item-source combinations, item repetition no longer affected source memory (Experiment 6). Overall, our findings did not support predictions based on item predifferentiation, within-dimension source interference, or general interference from multiple traces of an item. Rather, the findings were consistent with the idea that prior item repetition reduces attention to subsequent presentations of the item, decreasing the likelihood that critical item-source associations will be encoded.

  1. System incremental cost calculations using the participation factor load-flow formulation

    Meisel, J.

    1993-01-01

    The load-flow problem is reformulated such that the use of a slack-bus generator is included only as a special case. This reformulation, known as the participation factor load-flow, includes a total mismatch variable and a defined participation vector, which, in general, distributes this mismatch to all system buses. The slack-bus constraint can still be obtained by defining a particular participation vector. In using the participation factor load-flow in the transpose Jacobian approach to the economic optimal dispatch problem, the paper shows that the value of the system-λ can be controlled such that this value represents the minimal incremental change in generation costs per unit change in system total demand with this demand distributed according to the specified participation vector. Methods using the conventional B-coefficient loss formulas or slack-bus load-flows give system-λ values whereby the unit change in demand must be placed on a fictitious single load-bus or on the slack-bus, respectively. Having a system-λ value which more accurately represents a proposed energy interchange between interconnected systems is very important in developing valid costs for each system. An extensive 28-bus, 8-generator system is included to illustrate these results

  2. An experimental test of the persuasive effect of source similarity in narrative and nonnarrative health blogs.

    Blogs, or websites containing online personal journals, are a form of popular personal communication with immense potential for health promotion. Narratives are stories with a beginning, middle, and end that provide information about the characters and plot. Source similarity refers to the degree to which the message source and each recipient are alike with respect to certain attributes. Narratives and source similarity have seldom been examined in tandem as strategies for health persuasion. Personal health blogs provide a suitable platform for such an investigation. This study examined the persuasive effects of message type and source similarity on participants' intentions to adopt a specific health behavior (running for exercise). A total of 150 participants were randomly assigned to conditions (n=25 per condition) in a completely crossed, 2 (message type: narrative and nonnarrative) × 3 (source similarity: no similarity, non-health-related similarity, and health-related similarity) between-subjects experiment. First, in an online questionnaire, participants provided personal information in 42 categories and rated the relatedness of each category to running and then completed pretest measures of the dependent variables. Based on their responses, 150 personal health blogs were created. Two weeks later, the initial participants read the blog created with their personal characteristics and completed a questionnaire online. The source similarity effect was stronger in nonnarrative than narrative blogs. When the blogs were nonnarrative, those with health-related similarities were more persuasive than those with non-health-related similarities. Narrative blogs generated more positive thoughts and stronger blogger identification than nonnarrative blogs. Health-related source similarity is key for persuasive health communication, especially when the messages are nonnarrative.

    Full Text Available The battle of Blore Heath which took place on September 23, 1459, marked the new stage of the Wars of Roses, which led to the change of dynasties at the English throne in less than two years. As it was not the clash of the main forces of House of Lancaster and House of York, the sources contain poor information about the battle’s participants. However, the analysis different sources let identify the names of 22 participants. Prosopographic study of this group contributes to the study of social behavior models, the degree of influence of the Wars of Roses on English society, the activity of representatives of different social strata. The social structure of the group, most of which are the representatives of the English gentry, is the object of the article. There is information in the sources about the origin of the knights. The House of York under the command of Earl of Salisbury were mostly from Northern and North-Western counties (Yorkshire, Westmorland, whereas House of Lancaster formed their troops in Cheshire, Staffordshire and Lancashire. As a rule, officers in the army of the Earl of Salisbury, were in close personal or family ties with him. The study of further lives of the participants of the battle and biographies of their children showed that the adherence of the chosen dynasty was preserved by generations and change of the parties was rather a deviation from the norm. English nobility of the second half of the 15th century had a high opinion of the value of loyalty and honor.

    Full Text Available Abstract Background Web-based health behavior change programs can reach large groups of disparate participants and thus they provide promise of becoming important public health tools. Data on participant rurality can complement other demographic measures to deepen our understanding of the success of these programs. Specifically, analysis of participant rurality can inform recruitment and social marketing efforts, and facilitate the targeting and tailoring of program content. Rurality analysis can also help evaluate the effectiveness of interventions across population groupings. Methods We describe how the RUCAs (Rural-Urban Commuting Area Codes methodology can be used to examine results from two Randomized Controlled Trials of Web-based tobacco cessation programs: the ChewFree.com project for smokeless tobacco cessation and the Smokers' Health Improvement Program (SHIP project for smoking cessation. Results Using RUCAs methodology helped to highlight the extent to which both Web-based interventions reached a substantial percentage of rural participants. The ChewFree program was found to have more rural participation which is consistent with the greater prevalence of smokeless tobacco use in rural settings as well as ChewFree's multifaceted recruitment program that specifically targeted rural settings. Conclusion Researchers of Web-based health behavior change programs targeted to the US should routinely include RUCAs as a part of analyzing participant demographics. Researchers in other countries should examine rurality indices germane to their country.

    South Africa introduced the world's largest antiretroviral treatment (ART) program in 2004 and since 2016 the Department of Health implemented a universal Treatment as Prevention (TasP) strategy. However, some studies have shown that increasing the availability of ART is insufficient for the comprehensive treatment of HIV, since many people still use traditional health practitioners (THPs) to avoid being identified as HIV positive, and for reasons unrelated to HIV/AIDS. This qualitative study explored the factors influencing how both HIV-negative and HIV-positive people choose amongst multiple sources of healing and how they engage with them, in the context of HIV/AIDS and wide availability of ART. Data were collected as part of a larger TasP trial at the Africa Health Research Institute, KwaZulu-Natal. Repeat in-depth individual interviews were conducted with 10 participants. Repeat group discussions were conducted with 42 participants. Group discussion data were triangulated using community walks and photo-voice techniques to give more insight into the perceptions of community members. All data were collected over 18 months. Thematic analysis was used to analyze participants' narratives from both individual interviews and group discussions. In the context of HIV/AIDS and wide availability of ART, use of biomedical and traditional healing systems seemed to be common in this locality. People used THPs to meet family expectations, particularly those of authoritative heads of households such as parents or grandparents. Most participants believed that THPs could address specific types of illnesses, especially those understood to be spiritually caused and which could not be addressed or cured by biomedical practitioners. However, it was not easy for participants to separate some spiritually caused illnesses from biological illnesses in the context of HIV/AIDS. These data demonstrate that in this context, the use of THPs continues regardless of the wide availability

    A study was conducted in the Pleasant Valley Watershed (50 km 2) in South Central Wisconsin to better understand sediment transport processes using sediment fingerprinting technique. Previous studies conducted in this watershed showed that resuspension of fine sediment deposited on the stream bed is an important source of suspended sediment. To better understand the role of fine sediment deposited on the stream bed, fallout radionuclides,137Cs and 210Pbxs were used to determine relative contribution to suspended sediment from in-stream (stream bank and stream bed) and upland sediment sources. Suspended sediment samples were collected during the crop growing season. Potential sources of suspended sediment considered in this study included cropland, pasture and in-stream (stream bed and stream bank). Suspended sediment sources were determined at a subwatershed level. Results of this study showed that in-stream sediment sources are important sources of suspended sediment. Future research should be conducted to better understand the role of legacy sediment in watershed-level sediment transport processes.

    The characterization and control of runoff pollution from nonpoint sources in urban areas are a major issue for the protection of aquatic environments. We propose a methodology to quantify the sources of pollutants in an urban catchment and to analyze the associated uncertainties. After describing the methodology, we illustrate it through an application to the sources of Cu, Pb, Zn, and polycyclic aromatic hydrocarbons (PAH) from a residential catchment (228 ha) in the Paris region. In this application, we suggest several procedures that can be applied for the analysis of other pollutants in different catchments, including an estimation of the total extent of roof accessories (gutters and downspouts, watertight joints and valleys) in a catchment. These accessories result as the major source of Pb and as an important source of Zn in the example catchment, while activity-related sources (traffic, heating) are dominant for Cu (brake pad wear) and PAH (tire wear, atmospheric deposition).

    Construction of the Advanced Light Source (ALS) at the Lawrence Berkeley Laboratory is nearing completion, with operation as a US Department of Energy national user facility scheduled to begin in the spring of 1993. Based on a low-emittance, 1.5-GeV electron storage ring with 10 long straight sections available for insertion devices and, initially, 24 bend-magnet ports, the ALS will be a third-generation source of soft x-ray and ultraviolet (collectively, the XUV) synchrotron radiation. Experimental facilities (insertion devices, beamlines, and end stations) will be developed and operated by participating research teams working with the ALS staff. The ability to exploit the high spectral brightness of the ALS was the main criterion for PRT selection. In the XUV spectral regions served by the ALS, a major benefit of high brightness will be the ability to achieve spatial resolution in the neighborhood of 200 angstroms in x-ray microscopy and holography and in spatially resolved spectroscopy. Other beneficiaries of high brightness include very-high-resolution spectroscopy, spectroscopy of dilute species, diffraction from very small samples, and time-resolved spectroscopy and diffraction

    Communication campaigns are incorporating tobacco constituent messaging to reach smokers, yet there is a dearth of research on how such messages should be constructed or will be received by smokers. In a 2x2x2 experiment, we manipulated three cigarette constituent message components: (1) the toxic constituent of tobacco (arsenic vs. lead) with a corresponding health effect, (2) the presence or absence of an evocative image, and (3) the source of the message (FDA vs. no source). We recruited smokers (N = 1,669, 55.4% women) via an online platform and randomized them to 1 of the 8 message conditions. Participants viewed the message and rated its believability and perceived effectiveness, the credibility of the message source, and action expectancies (i.e., likelihood of seeking additional information and help with quitting as a result of seeing the message). We found significant main effects of image, constituent, and source on outcomes. The use of arsenic as the constituent, the presence of an evocative image, and the FDA as the source increased the believability, source credibility, and perceived effectiveness of the tobacco constituent health message. Multiple elements of a constituent message, including type of constituent, imagery, and message source, impact their reception among smokers. Specifically, communication campaigns targeting smokers that utilize arsenic as the tobacco constituent, visual imagery, and the FDA logo may be particularly effective in changing key outcomes that are associated with subsequent attitude and behavioral changes. This paper describes how components of communication campaigns about cigarette constituents are perceived. Multiple elements of a tobacco constituent message, including type of constituent, image, and message source may influence the reception of messages among current smokers. Communication campaigns targeting smokers that utilize arsenic as the tobacco constituent, visual imagery, and the FDA logo may be particularly

  10. Testing the Motor Simulation Account of Source Errors for Actions in Recall

    2017-09-01

    Full Text Available Observing someone else perform an action can lead to false memories of self-performance – the observation inflation effect. One explanation is that action simulation via mirror neuron activation during action observation is responsible for observation inflation by enriching memories of observed actions with motor representations. In three experiments we investigated this account of source memory failures, using a novel paradigm that minimized influences of verbalization and prior object knowledge. Participants worked in pairs to take turns acting out geometric shapes and letters. The next day, participants recalled either actions they had performed or those they had observed. Experiment 1 showed that participants falsely retrieved observed actions as self-performed, but also retrieved self-performed actions as observed. Experiment 2 showed that preventing participants from encoding observed actions motorically by taxing their motor system with a concurrent motor task did not lead to the predicted decrease in false claims of self-performance. Indeed, Experiment 3 showed that this was the case even if participants were asked to carefully monitor their recall. Because our data provide no evidence for a motor activation account, we also discussed our results in light of a source monitoring account.

  11. Crowd Sourcing.

    2016-01-01

    The Internet has contributed new words and slang to our daily vernacular. A few terms, such as tweeting, texting, sexting, blogging, and googling, have become common in most vocabularies and in many languages, and are now included in the dictionary. A new buzzword making the rounds in industry is crowd sourcing, which involves outsourcing an activity, task, or problem by sending it to people or groups outside a business or a practice. Crowd sourcing allows doctors and practices to tap the wisdom of many instead of relying only on the few members of their close-knit group. This article defines "crowd sourcing," offers examples, and explains how to get started with this approach that can increase your ability to finish a task or solve problems that you don't have the time or expertise to accomplish.

    Luck, Lauretta; Chok, Harrison Ng; Wilkes, Lesley

    2017-09-19

    Recruitment and retention of participants, as well as response rates, can be challenging in nursing research. This can be because of the questions asked; the choice of methodology; the methods used to collect data; the characteristics of potential participants; the sample size required; and the duration of the study. Additionally, conducting research with nurses as participants presents several issues for them, including the time needed to participate in the research, the competing commitments for clinical practice, the political and environmental climate, and recruitment itself. To report on research studies conducted by the authors at a tertiary teaching hospital, to show the lessons learned when recruiting nurses to participate in nursing research. The authors discuss factors that supported recruitment of nurses in these studies, including the use of the personal touch and multiple recruitment strategies in a single study. Videos and photography facilitate interdisciplinary research and can be a valuable means of non-verbal data collection, especially with participants affected by disabilities, and can support research methods, such as the use of questionnaires. Recruiting nurses for research can be challenging. We suggest that researchers consider using more than one recruitment strategy when recruiting nurse participants. Recruitment is more successful if researchers align the aim(s) of the research with nurse's concerns and contexts. ©2012 RCN Publishing Company Ltd. All rights reserved.

    2016-08-01

    This paper describes a qualitative study that investigated the nature of the participation structures and how the participation structures were organized by four science teachers when they constructed and communicated science content in their classrooms with computer technology. Participation structures focus on the activity structures and processes in social settings like classrooms thereby providing glimpses into the complex dynamics of teacher-students interactions, configurations, and conventions during collective meaning making and knowledge creation. Data included observations, interviews, and focus group interviews. Analysis revealed that the dominant participation structure evident within participants' instruction with computer technology was ( Teacher) initiation-( Student and Teacher) response sequences-( Teacher) evaluate participation structure. Three key events characterized the how participants organized this participation structure in their classrooms: setting the stage for interactive instruction, the joint activity, and maintaining accountability. Implications include the following: (1) teacher educators need to tap into the knowledge base that underscores science teachers' learning to teach philosophies when computer technology is used in instruction. (2) Teacher educators need to emphasize the essential idea that learning and cognition is not situated within the computer technology but within the pedagogical practices, specifically the participation structures. (3) The pedagogical practices developed with the integration or with the use of computer technology underscored by the teachers' own knowledge of classroom contexts and curriculum needs to be the focus for how students learn science content with computer technology instead of just focusing on how computer technology solely supports students learning of science content.

  16. Use of multiple data sources to estimate hepatitis C seroprevalence among prisoners: A retrospective cohort study.

    Kathryn J Snow

    Full Text Available Hepatitis C is a major cause of preventable morbidity and mortality. Prisoners are a key population for hepatitis C control programs, and with the advent of highly effective therapies, prisons are increasingly important sites for hepatitis C diagnosis and treatment. Accurate estimates of hepatitis C prevalence among prisoners are needed in order to plan and resource service provision, however many prevalence estimates are based on surveys compromised by limited and potentially biased participation. We aimed to compare estimates derived from three different data sources, and to assess whether the use of self-report as a supplementary data source may help researchers assess the risk of selection bias. We used three data sources to estimate the prevalence of hepatitis C antibodies in a large cohort of Australian prisoners-prison medical records, self-reported status during a face-to-face interview prior to release from prison, and data from a statewide notifiable conditions surveillance system. Of 1,315 participants, 33.8% had at least one indicator of hepatitis C seropositivity, however less than one third of these (9.5% of the entire cohort were identified by all three data sources. Among participants of known status, self-report had a sensitivity of 80.1% and a positive predictive value of 97.8%. Any one data source used in isolation would have under-estimated the prevalence of hepatitis C in this cohort. Using multiple data sources in studies of hepatitis C seroprevalence among prisoners may improve case detection and help researchers assess the risk of selection bias due to non-participation in serological testing.

    Conclusion: Sports participation has previously been shown to confer a number of health benefits; as such, school sports programs may be an important, effective, and underused target for public health efforts, including obesity prevention programs. Efforts to increase physical activity among youth should consider both access and choice in school athletic programs. Schools may need to use different strategies to increase sports participation in boys and girls.

    2015-01-01

    Deaf individuals have more cardiovascular risks than the general population that are believed to be related to their cardiovascular health knowledge disparities. This phenomenological study describes where 20 deaf sign language-using adolescents from Rochester, New York, many who possess many positive characteristics to support their health literacy, learn cardiovascular health information and their lived experiences accessing health information. The goal is to ultimately use this information to improve the delivery of cardiovascular health education to this population and other deaf adolescents at a higher risk for weak health literacy. Deaf bilingual researchers interviewed deaf adolescents, transcribed and coded the data, and described the findings. Five major sources of cardiovascular health information were identified including family, health education teachers, healthcare providers, printed materials, and informal sources. Despite possessing advantageous characteristics contributing to stronger health literacy, study participants described significant challenges with accessing health information from each source. They also demonstrated inconsistencies in their cardiovascular health knowledge, especially regarding heart attack, stroke, and cholesterol. These findings suggest a great need for additional public funding to research deaf adolescents’ informal health-related learning, develop accessible and culturally appropriate health surveys and health education programming, improve interpreter education, and disseminate information through social media.

  6. The role of executive function in children's source monitoring with varying retrieval strategies

    Earhart, Becky; Roberts, Kim P.

    2014-01-01

    Previous research on the relationship between executive function and source monitoring in young children has been inconclusive, with studies finding conflicting results about whether working memory and inhibitory control are related to source-monitoring ability. In this study, the role of working memory and inhibitory control in recognition memory and source monitoring with two different retrieval strategies were examined. Children (N = 263) aged 4–8 participated in science activities with two sources. They were later given a recognition and source-monitoring test, and completed measures of working memory and inhibitory control. During the source-monitoring test, half of the participants were asked about sources serially (one after the other) whereas the other half of the children were asked about sources in parallel (considering both sources simultaneously). Results demonstrated that working memory was a predictor of source-monitoring accuracy in both conditions, but inhibitory control was only related to source accuracy in the parallel condition. When age was controlled these relationships were no longer significant, suggesting that a more general cognitive development factor is a stronger predictor of source monitoring than executive function alone. Interestingly, the children aged 4–6 years made more accurate source decisions in the parallel condition than in the serial condition. The older children (aged 7–8) were overall more accurate than the younger children, and their accuracy did not differ as a function of interview condition. Suggestions are provided to guide further research in this area that will clarify the diverse results of previous studies examining whether executive function is a cognitive prerequisite for effective source monitoring.

  7. Nurturing reliable and robust open-source scientific software

    Science.gov (United States)

    Uieda, L.; Wessel, P.

    2017-12-01

    Scientific results are increasingly the product of software. The reproducibility and validity of published results cannot be ensured without access to the source code of the software used to produce them. Therefore, the code itself is a fundamental part of the methodology and must be published along with the results. With such a reliance on software, it is troubling that most scientists do not receive formal training in software development. Tools such as version control, continuous integration, and automated testing are routinely used in industry to ensure the correctness and robustness of software. However, many scientist do not even know of their existence (although efforts like Software Carpentry are having an impact on this issue; software-carpentry.org). Publishing the source code is only the first step in creating an open-source project. For a project to grow it must provide documentation, participation guidelines, and a welcoming environment for new contributors. Expanding the project community is often more challenging than the technical aspects of software development. Maintainers must invest time to enforce the rules of the project and to onboard new members, which can be difficult to justify in the context of the "publish or perish" mentality. This problem will continue as long as software contributions are not recognized as valid scholarship by hiring and tenure committees. Furthermore, there are still unsolved problems in providing attribution for software contributions. Many journals and metrics of academic productivity do not recognize citations to sources other than traditional publications. Thus, some authors choose to publish an article about the software and use it as a citation marker. One issue with this approach is that updating the reference to include new contributors involves writing and publishing a new article. A better approach would be to cite a permanent archive of individual versions of the source code in services such as Zenodo

    This study examines the gender differences in the enjoyment of recreational sports participation among Taiwanese adults. Data were obtained using the 2007 Taiwan Social Change Survey. The questionnaire included a topical module of the International Social Survey Program regarding leisure time and sports. Results showed that male subjects were more likely to participate in recreational sports to improve their appearance and on account of their personal interest. In addition to these factors, female subjects also experienced greater motivation to participate when Taiwanese athletes performed well in international sporting competitions. This study confirmed that the factors influencing enjoyment of recreational sports participation differ among men and women. These results can be used to better inform public health professionals and other regulatory organizations formulating physical activity intervention strategies.

    Dillon, Daniel G; Dobbins, Ian G; Pizzagalli, Diego A

    2014-10-01

    Reward responses in the medial temporal lobes and dopaminergic midbrain boost episodic memory formation in healthy adults, and weak memory for emotionally positive material in depression suggests this mechanism may be dysfunctional in major depressive disorder (MDD). To test this hypothesis, we performed a study in which unmedicated adults with MDD and healthy controls encoded drawings paired with reward or zero tokens during functional magnetic resonance imaging. In a recognition test, participants judged whether drawings were previously associated with the reward token ('reward source') or the zero token ('zero source'). Unlike controls, depressed participants failed to show better memory for drawings from the reward source vs the zero source. Consistent with predictions, controls also showed a stronger encoding response to reward tokens vs zero tokens in the right parahippocampus and dopaminergic midbrain, whereas the MDD group showed the opposite pattern-stronger responses to zero vs reward tokens-in these regions. Differential activation of the dopaminergic midbrain by reward vs zero tokens was positively correlated with the reward source memory advantage in controls, but not depressed participants. These data suggest that weaker memory for positive material in depression reflects blunted encoding responses in the dopaminergic midbrain and medial temporal lobes. © The Author (2013).

    Norway is a member of Annex 29, 'Ground-Source Heat Pump Systems Overcoming Technical and Market Barriers' (2004-2006), organized under the umbrella of the International Energy Agency (IEA) and the IEA Heat Pump Programme (HPP). The 7 participating countries are Austria (Operating Agent), Canada, Japan, Norway, Spain, Sweden and the USA. The Norwegian participation is financed by ENOVA SF, and SINTEF Energy Research is responsible for planning and carrying out the Norwegian activities. This report provides a status for ground-source heat pump (GSHP) systems in Norway with regard to state-of-the-art technology, installation examples, geological data, costs and market opportunities. A Norwegian Internet home page for ground-source heat pump systems (www.energy.sintef.no/prosjekt/Annex29) is also presented. GSHP systems in Norway are classified as direct systems (groundwater and soil/ground) and indirect closed-loop systems (vertical-rock and horizontal-soil/ground). The vast majority of the installations are indirect closed-loop systems utilizing vertical boreholes in rock as a heat source, heat sink and thermal energy storage. GSHP systems are relatively capital intensive installations, but they achieve high energy efficiency due to the relatively high and stable heat source temperature and the fact that a considerable share of the cooling demand in non-residential buildings can be covered by means of free cooling. In order to obtain energy efficient and reliable GSHP installations, it is important to implement a total quality concept where focus is on quality and system integration during all stages of the project. A life cycle analysis (LCA) will be an important tool in such a concept, since both the investment costs as well as the lifetime operational and maintenance costs are included (author) (ml) Litt usikker pae tag 620- ikke en vanlig sintef rapportkode

    2018-02-01

    Temporal sources of dream threats were examined through the paradigm of the Threat Simulation Theory. Two groups of young adults (18-24 years old), who did not experience severe threatening events in the year preceding their dream and reported a dream either with or without threats, were included. Participants (N = 119) kept a log of daily activities and a dream diary, indicating whether dream components referred to past experiences. The occurrence of oneiric threats correlated with the reporting of threats in the daily logs, their average severity, and the stress level experienced the day preceding the dream. The group whose dreams contained threats had significantly more references to temporal categories beyond one year than the group with dreams without threats. Our findings suggest that in the absence of recent highly negative emotional experiences, the threat simulation system selects memory traces of threatening events experienced in the past.

    We give an overview of ISINA: INTEGRAL Source Identification Network Algorithm. This machine learning algorithm, using random forests, is applied to the IBIS/ISGRI data set in order to ease the production of unbiased future soft gamma-ray source catalogues. First, we introduce the data set and the problems encountered when dealing with images obtained using the coded mask technique. The initial step of source candidate searching is introduced and an initial candidate list is created. A description of the feature extraction on the initial candidate list is then performed together with feature merging for these candidates. Three training and testing sets are created in order to deal with the diverse time-scales encountered when dealing with the gamma-ray sky. Three independent random forests are built: one dealing with faint persistent source recognition, one dealing with strong persistent sources and a final one dealing with transients. For the latter, a new transient detection technique is introduced and described: the transient matrix. Finally the performance of the network is assessed and discussed using the testing set and some illustrative source examples. Based on observations with INTEGRAL, an ESA project with instruments and science data centre funded by ESA member states (especially the PI countries: Denmark, France, Germany, Italy, Spain), Czech Republic and Poland, and the participation of Russia and the USA.

    2014-03-01

    The last two decades have witnessed tremendous advances in the field of reproductive medicine, especially assisted reproductive technology and stem cell research. As research continues in future, it is vital to ensure that individuals from all ethnic backgrounds are represented in the study populations so that the findings of the research can be generalised for the benefit of all. Many studies, however, have noted a trend of low participation rates amongst Asian women in reproductive research. Inequalities in the ethnicity of research participants can be a source of substantial bias, and have major ethical and scientific ramifications. Several factors such as educational status, fear of wrong-doing, communication barriers, and socio-cultural beliefs have been suggested to play a role. There is a need for further exploration of the factors influencing Asian women's decision to accept or decline participation in reproductive research and for development of effective targeted strategies for research recruitment with the aim of encouraging research participation as well as donation of cryopreserved embryos or other reproductive tissues.

    The peer group begins to become a source of support during late childhood and adolescence making it important to understand what type of help young people might suggest to a friend with an emotional or behavioral problem. Three groups of young people participated in the study with average ages of 12 (N = 107), 14 (N = 153) and 16 years (N = 133). All participants were presented with vignettes describing fictional peers, two of whom had symptoms of clinical problems (ADHD and depression) and a third comparison peer without symptoms. Results indicate that all participants distinguished between clinical and comparison vignette characters and they believed that the characters with clinical symptoms needed help. The 16-year-olds were more likely to differentiate between the two clinical vignettes in terms of the type of help suggested. The results are discussed in light of previous research on adolescents' understanding of sources of help for mental health problems.

    The Chandra Source Catalog (CSC) is breaking new ground in several areas. There are two aspects that are of particular interest to the users: its evolution and its contents. The CSC will be a living catalog that becomes richer, bigger, and better in time while still remembering its state at each point in time. This means that users will be able to take full advantage of new additions to the catalog, while retaining the ability to back-track and return to what was extracted in the past. The CSC sheds the limitations of flat-table catalogs. Its sources will be characterized by a large number of properties, as usual, but each source will also be associated with its own specific data products, allowing users to perform mini custom analysis on the sources. Source properties fall in the spatial (position, extent), photometric (fluxes, count rates), spectral (hardness ratios, standard spectral fits), and temporal (variability probabilities) domains, and are all accompanied by error estimates. Data products cover the same coordinate space and include event lists, images, spectra, and light curves. In addition, the catalog contains data products covering complete observations: event lists, background images, exposure maps, etc. This work is supported by NASA contract NAS8-03060 (CXC).

    Friedman, Carly K; Morgan, Elizabeth M

    2009-08-01

    The present study provides a comparative analysis of sexual-minority and heterosexual emerging adult women's experiences seeking support for sexual issues from parents and friends. Participants included 229 college women (88 sexual-minority women; 141 heterosexual women), ranging from 18 to 25 years of age, who provided written responses to an inquiry about a time they went to friends and parents for support for a issue related to their sexuality. Responses indicated that the majority of participants had sought support from either a parent or a friend and that mothers and female friends were more likely involved than fathers or male friends, respectively. Sexual issues that participants reported discussing with parents and friends were inductively grouped into five categories: dating and romantic relationships, sexual behavior, sexual health, identity negotiation, and discrimination and violence. Issues that were discussed differed based on sexual orientation identity and the source of support (parent or friend); they did not differ by age. Participants generally perceived parents and friends' responses as helpful, though sexual-minority participants perceived both parents and friends' responses as less helpful than did heterosexual participants. Overall, results suggest both similarities and differences between sexual-minority and heterosexual young women's experiences seeking support for sexual issues from parents and friends.

    The second Source Physics Experiment shot (SPE-2) was conducted in Nevada on October 25, 2011, at 1900:00.011623 Greenwich Mean Time (GMT). The explosive source was 997 kilograms (kg) trinitrotoluene (TNT) equivalent of sensitized heavy ammonium fuel oil (SHANFO) detonated at a depth of 45.7 meters (m). The third Source Physics Experiment shot (SPE-3) was conducted in Nevada on July 24, 2012, at 1800:00.44835 GMT. The explosive source was 905 kg TNT equivalent of SHANFO detonated at a depth of 45.8 m. Both shots were recorded by an extensive set of instrumentation that includes sensors both at near-field (less than 100 m) and far-field (100 m or greater) distances. The near-field instruments consisted of three-component accelerometers deployed in boreholes at 15, 46, and 55 m depths around the shot and a set of single-component vertical accelerometers on the surface. The far-field network was composed of a variety of seismic and acoustic sensors, including short-period geophones, broadband seismometers, three-component accelerometers, and rotational seismometers at distances of 100 m to 25 kilometers. This report coincides with the release of these data for analysts and organizations that are not participants in this program. This report describes the second and third Source Physics Experiment shots and the various types of near-field and far-field data that are available.

    Allison, Rosalie; Bird, Emma L; McClean, Stuart

    2017-01-01

    It is estimated that 21% of boys and 16% of girls in England meet recommended physical activity guidelines. Team sport has the potential to increase physical activity levels; however, studies show that gender-based factors can influence girls' participation in team sport. Furthermore, evidence for the effectiveness of interventions promoting team sport among girls is limited. This systematic review aimed to assess the impact of physical activity interventions on secondary school-aged girls' (aged 11-18 years) participation in team sport and to identify potential strategies for increasing participation. Electronic databases and grey literature were systematically searched for studies of interventions targeting team sport participation among girls in the UK. Results were exported to Refworks, duplicates removed and eligible studies identified. Extracted data included: participant details, such as sample size and age; components of the intervention; outcomes assessed; and each study was quality appraised. Due to heterogeneity across studies, results were presented narratively. Four studies sourced from the grey literature met the inclusion criteria. Findings suggest that physical activity interventions can encourage girls to try new sports, but evidence is limited in relation to sustained participation. Potential strategies for promoting participation included: consultation with girls, implementation of appropriate peer-leaders and friendship group strategies, early intervention and consideration of intervention setting. This review highlights the limited availability of evidence on the effectiveness of physical activity interventions for promoting team sport participation among girls in the UK. Findings indicate that future research is needed to improve the methodological quality of complex intervention evaluation. Physical activity interventions may have the potential to encourage girls to try team sport, but their impact on sustained participation, and subsequent

    Four kinds of negative ion sources (direct extraction Duoplasmatron ion source, radial extraction Penniing ion source, lithium charge exchange ion source and Middleton-type sputter ion source) have been installed in the JAERI tandem accelerator. The ion sources can generate many negative ions ranging from Hydrogen to Uranium with the exception of Ne, Ar, Kr, Xe and Rn. Discussions presented in this report include mechanisms of negative ion formation, electron affinity and stability of negative ions, performance of the ion sources and materials used for negative ion production. Finally, the author will discuss difficult problems to be overcome in order to get any negative ion sufficiently. (author)

    BACKGROUND Questionnaire surveys are important for surveying the health and disease behaviour of the population, but recent years have seen a fall in participation. Our study tested whether incentives can increase participation in these surveys.MATERIAL AND METHOD We sent a questionnaire on risk factors for colorectal cancer (height, weight, smoking, self-reported diagnoses, family medical history) to non-screened participants in a randomised colonoscopy screening study for colorectal cancer: participants who were invited but did not attend for colonoscopy examination (screening-invited) and persons who were not offered colonoscopy (control group). The persons were randomised to three groups: no financial incentive, lottery scratch cards included with the form, or a prize draw for a tablet computer when they responded to the form. We followed up all the incentive groups with telephone reminder calls, and before the prize draw for the tablet computer.RESULTS Altogether 3 705 of 6 795 persons (54.5  %) responded to the questionnaire; 43.5  % of those invited for screening and 65.6  % of the control group (p reminder calls, 39.2  % responded.

    2014-12-01

    This paper compares farm efficiencies between dairies who were participating in a veterinary herd health management (VHHM) program with dairies not participating in such a program, to determine whether participation has an association with farm efficiency. In 2011, 572 dairy farmers received a questionnaire concerning the participation and execution of a VHHM program on their farms. Data from the questionnaire were combined with farm accountancy data from 2008 through 2012 from farms that used calendar year accounting periods, and were analyzed using Stochastic Frontier Analysis (SFA). Two separate models were specified: model 1 was the basic stochastic frontier model (output: total revenue; input: feed costs, land costs, cattle costs, non-operational costs), without explanatory variables embedded into the efficiency component of the error term. Model 2 was an expansion of model 1 which included explanatory variables (number of FTE; total kg milk delivered; price of concentrate; milk per hectare; cows per FTE; nutritional yield per hectare) inserted into the efficiency component of the joint error term. Both models were estimated with the financial parameters expressed per 100 kg fat and protein corrected milk and per cow. Land costs, cattle costs, feed costs and non-operational costs were statistically significant and positive in all models (P<0.01). Frequency distributions of the efficiency scores for the VHHM dairies and the non-VHHM dairies were plotted in a kernel density plot, and differences were tested using the Kolmogorov-Smirnov two-sample test. VHHM dairies had higher total revenue per cow, but not per 100 kg milk. For all SFA models, the difference in distribution was not statistically different between VHHM dairies and non-VHHM dairies (P values 0.94, 0.35, 0.95 and 0.89 for the basic and complete model per 100 kg fat and protein corrected milk and per cow respectively). Therefore we conclude that with our data farm participation in VHHM is not related

    The document provides potential participants with the essential technical information to permit them to participate in the IMO-administered markets, and is not intended to be a complete technical reference manual for all issues within the realm of electricity production, distribution, or consumption. Written for the participants, it provides only that information which is relevant to the participant for interfacing with the IMO and participating in the market. Written as a generic guide, all the information contained within it may not be relevant to all the participants. The document's intent is to provide participants with a description of the various facilities and interfaces required by market participants to take part in the IMO-administered markets. The document supplements the market rules and provides installation, set-up, and configuration information for the various tools and facilities that will be required for market participation as a supplier, carrier/delivery (transmitter/distributor), generator, or consumer in the market. Aspects considered include: participant workstation specifications, dispatch workstation specification, message exchange, remote terminal unit specification, AGC operational RTU specification, real time network connection specification, telephone connection specification, revenue administration specification, funds administration specification, data catalogues, market information, power grid connection requirements, and appendices

    2011-07-01

    Full Text Available Abstract Background Low participation in population-based follow-up studies addressing psychosocial risk factors may cause biased estimation of health risk but the issue has seldom been examined. We compared risk estimates for selected health outcomes among respondents and the entire source population. Methods In a Danish cohort study of associations between psychosocial characteristics of the work environment and mental health, the source population of public service workers comprised 10,036 employees in 502 work units of which 4,489 participated (participation rate 45%. Data on the psychosocial work environment were obtained for each work unit by calculating the average of the employee self-reports. The average values were assigned all employees and non-respondent at the work unit. Outcome data on sick leave and prescription of antidepressant medication during the follow-up period (1.4.2007-31.12.2008 was obtained by linkage to national registries. Results Respondents differed at baseline from non-respondents by gender, age, employment status, sick leave and hospitalization for affective disorders. However, risk estimates for sick leave and prescription of antidepressant medication, during follow-up, based on the subset of participants, did only differ marginally from risk estimates based upon the entire population. Conclusions We found no indications that low participation at baseline distorts the estimates of associations between the work unit level of psychosocial work environment and mental health outcomes during follow-up. These results may not be valid for other exposures or outcomes.

    The results for Problems 5 and 6 of the NEACRP code comparison as submitted by six participating countries are presented in summary. These problems concentrate on the prediction of the neutron and gamma-ray sources arising in fuel after a specified irradiation, the fuel being uranium oxide for problem 5 and a mixture of uranium and plutonium oxides for problem 6. In both problems the predicted neutron sources are in good agreement for all participants. For gamma rays, however, there are differences, largely due to the omission of bremsstrahlung in some calculations

    2011-01-01

    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.

    2014-03-01

    Although participation and empowerment are hallmarks of the WHO vision of health promotion, it is acknowledged that they are difficult to evaluate. Devising adequate study designs, indicators and methods for the assessment of participation and empowerment should consider the experiences, concerns and constraints of health promotion practitioners. The aim of this study was to investigate health promotion practitioners' perspectives on general and methodological aspects of evaluation of empowerment and participation. Semi-structured interviews were conducted with 17 experienced practitioners in community-based health promotion in New South Wales, Australia. The interviews covered benefits of and barriers to the evaluation of participation and empowerment, key indicators and methodological aspects. Interview transcripts were examined using thematic content analysis. The idea of evaluating empowerment and participation is supported by health promotion practitioners. Including indicators of empowerment and participation in the evaluation could also emphasise-to practitioners and citizens alike-the value of involving and enabling community members. The interviews highlighted the importance of a receptive environment for evaluation of empowerment and participation to take root. The resistance of health authorities towards empowerment indicators was seen as a challenge for funding evaluations. Community members should be included in the evaluation process, although interviewees found it difficult to do so in a representative way and empowering approach. Qualitative methods might capture best whether empowerment and participation have occurred in a programme. The positive experiences that the interviewees made with innovative qualitative methods encourage further investment in developing new research designs.

    A light source is provided by a photonic crystal having an enhanced photonic density-of-states over a band of frequencies and wherein at least one of the dielectric materials of the photonic crystal has a complex dielectric constant, thereby producing enhanced light emission at the band of frequencies when the photonic crystal is heated. The dielectric material can be a metal, such as tungsten. The spectral properties of the light source can be easily tuned by modification of the photonic crystal structure and materials. The photonic crystal light source can be heated electrically or other heating means. The light source can further include additional photonic crystals that exhibit enhanced light emission at a different band of frequencies to provide for color mixing. The photonic crystal light source may have applications in optical telecommunications, information displays, energy conversion, sensors, and other optical applications.

    With the rapid development in IT and the emergence of Internet, a multitude of information sources are now available on electronic media. They include e-journals and other electronic publications - online databases, reference documents, newspapers, magazines, etc. In addition to these online sources, there are thousands of CD-ROM databases. The CD-ROM databases and the online sources are collectively referred to as electronic sources of information. Libraries in no part of the world can afford to ignore these sources. Emergence of these new sources has resulted into a change in the traditional library functions including collection development, acquisitions, cataloguing, user instructions, etc. It is inevitable that in the next five to ten years, special libraries may have to allocate considerable amount towards subscription of e-journals and other e-publications. The papers in this seminar volume discuss several aspects related the theme of the seminar and cover e-journals, different sources available in the Net, classification of electronic sources, online public access catalogues, and different aspects of Internet. Papers relevant to INIS are indexed separately

    Automated eHealth Web-based research trials offer people an accessible, confidential opportunity to engage in research that matters to them. eHealth trials may be particularly useful for sensitive issues when seeking health care may be accompanied by shame and mistrust. Yet little is known about people's early engagement with eHealth trials, from recruitment to preintervention autoregistration processes. A recent randomized controlled trial that tested the effectiveness of an eHealth safety decision aid for New Zealand women in the general population who experienced intimate partner violence (isafe) provided the opportunity to examine recruitment and preintervention participant engagement with a fully automated Web-based registration process. The trial aimed to recruit 340 women within 24 months. The objective of our study was to examine participant preintervention engagement and recruitment efficiency for the isafe trial, and to analyze dropout through the registration pathway, from recruitment to eligibility screening and consent, to completion of baseline measures. In this case study, data collection sources included the trial recruitment log, Google Analytics reports, registration and program metadata, and costs. Analysis included a qualitative narrative of the recruitment experience and descriptive statistics of preintervention participant engagement and dropout rates. A Koyck model investigated the relationship between Web-based online marketing website advertisements (ads) and participant accrual. The isafe trial was launched on September 17, 2012. Placement of ads in an online classified advertising platform increased the average number of recruited participants per month from 2 to 25. Over the 23-month recruitment period, the registration website recorded 4176 unique visitors. Among 1003 women meeting eligibility criteria, 51.55% (517) consented to participate; among the 501 women who enrolled (consented, validated, and randomized), 412 (82.2%) were

    Periacetabular osteotomy (PAO) is an effective treatment for symptomatic acetabular dysplasia. However, whether postoperative participation in sports leads to progression of the Kellgren-Lawrence (KL) grade of osteoarthritis (OA) in these patients is unclear. To investigate (1) participation in sports before and after PAO and (2) whether postoperative participation in sports leads to progression of the KL grade. Case-control study; Level of evidence, 3. The authors retrospectively reviewed data on 161 patients (183 hips) who underwent PAO for symptomatic acetabular dysplasia with preoperative KL grade 1 or 2 between 1998 and 2011. The mean age at the time of surgery was 42.0 ± 10.9 years (range, 12-64 years), and the mean follow-up duration was 100 months (range, 13-180 months). Data included participation in sports, the University of California, Los Angeles (UCLA) activity scale score, age at the time of surgery, body mass index, follow-up duration, history of treatment for developmental hip dislocations, Merle d'Aubigné-Postel score, Oxford Hip Score, center-edge angle, and KL grade. Univariate and multivariate analyses were applied to determine which factors were associated with progression to KL grade 3 or 4 after PAO. The number of patients who participated in sports significantly increased from 50 (31.1%) preoperatively to 89 (55.3%) postoperatively. The mean UCLA score significantly increased from 4.7 ± 2.1 preoperatively to 5.5 ± 2.0 postoperatively. The KL grade progressed to grade 3 or 4 in 16 hips, including 4 hips that underwent conversion to total hip arthroplasty. No significant differences were found in postoperative participation in sports (89 hips [53.3%] vs 11 hips [68.8%], respectively; P = .24) and the UCLA score (5.6 ± 2.0 vs 5.1 ± 2.0, respectively; P = .30) between hips with KL grade 1 or 2 and KL grade 3 or 4. A multivariate analysis revealed that no factors, including postoperative participation in sports, were significantly

    The first release of the Chandra Source Catalog (CSC) contains all sources identified from eight years' worth of publicly accessible observations. The vast majority of these sources have been observed with the ACIS detector and have spectral information in 0.5-7 keV energy range. Here we describe the methods used to automatically derive spectral properties for each source detected by the standard processing pipeline and included in the final CSC. Hardness ratios were calculated for each source between pairs of energy bands (soft, medium and hard) using the Bayesian algorithm (BEHR, Park et al. 2006). The sources with high signal to noise ratio (exceeding 150 net counts) were fit in Sherpa (the modeling and fitting application from the Chandra Interactive Analysis of Observations package, developed by the Chandra X-ray Center; see Freeman et al. 2001). Two models were fit to each source: an absorbed power law and a blackbody emission. The fitted parameter values for the power-law and blackbody models were included in the catalog with the calculated flux for each model. The CSC also provides the source energy flux computed from the normalizations of predefined power-law and black-body models needed to match the observed net X-ray counts. In addition, we provide access to data products for each source: a file with source spectrum, the background spectrum, and the spectral response of the detector. This work is supported by NASA contract NAS8-03060 (CXC).

    Historically, people living with mental illness have had limited chance to participate in mental health services other than as patients. Following on from a recent review focusing on consumer participation in mental health services, this paper looks at consumer participation in housing. Housing is a critical element in recovery from mental illness. Without suitable housing, people have little chance of maintaining other resources in their lives, such as supportive social relationships and meaningful activities. Consumer participation is not a common topic in the recent literature, despite the significant public policy push to promote it. The importance of appropriate housing to the recovery of people living with mental illness cannot be underestimated. Even well-meaning and well-resourced housing initiatives can fall short of meeting consumers' recovery goals when they do not incorporate the expressed needs of consumers. These expressed needs include keeping units small in size and employing drop-in support models.

  13. Sealed radioactive source management

    International Nuclear Information System (INIS)

    2005-01-01

    Sealed radioactive sources have been used in a wide range of application in medicine, agriculture, geology, industry and other fields. Since its utilization many sources have become out of use and became waste but no proper management. This has lead to many accidents causing deaths and serious radiation injuries worldwide. Spent sources application is expanding but their management has seen little improvements. Sealed radioactive sources have become a security risk calling for prompt action. Source management helps to maintain sources in a good physical status and provide means of source tracking and control. It also provides a well documented process of the sources making any future management options safe, secure and cost effective. Last but not least good source management substantially reduces the risk of accidents and eliminates the risk of malicious use. The International Atomic Energy Agency assists Member States to build the infrastructure to properly manage sealed radioactive sources. The assistance includes training of national experts to handle, condition and properly store the sources. For Member States that do not have proper facilities, we provide the technical assistance to design a proper facility to properly manage the radioactive sources and provide for their proper storage. For Member States that need to condition their sources properly but don't have the required infrastructure we provide direct assistance to physically help them with source recovery and provide an international expert team to properly condition their sources and render them safe and secure. We offer software (Radioactive Waste Management Registry) to properly keep a complete record on the sources and provide for efficient tracking. This also helps with proper planning and decision making for long term management

    2016-01-01

    Incidents with hazardous radiation sources can occur in any country, even those without nuclear facilities. Preparedness for such incidents is supposed to fulfill globally agreed minimum standards. Incidents are categorized in incidents with licensed handling of radiation sources as for material testing, transport accidents of hazardous radiation sources, incidents with radionuclide batteries, incidents with satellites containing radioactive inventory, incidents wit not licensed handling of illegally acquired hazardous radiation sources. The emergency planning in Austria includes a differentiation according to the consequences: incidents with release of radioactive materials resulting in restricted contamination, incidents with release of radioactive materials resulting in local contamination, and incidents with the hazard of e@nhanced exposure due to the radiation source.

    Objective. To assess teaching certificate program (TCP) participants' perceptions of mentor-mentee relationships. Methods. A 15-item survey instrument was administered to all 2014-2015 participants of the Indiana Pharmacy Teaching Certificate (IPTeC) program. Results. One hundred percent of IPTeC program participants (83/83) responded to the survey. The majority of participants indicated that having a professional mentor was either very important (52%) or important (47%) to their professional development and preferred to choose their own professional mentor (53%). Mentor characteristics rated as highly important by mentees included having similar clinical practice interests (82%), having similar research interests (66%), and being available to meet face-to-face (90%). Age, race, and gender of the mentor were not rated by mentees as important. Conclusion. Teaching certificate program participants place high importance on having a professional mentor. Mentorship of pharmacists completing TCPs should be a priority for current pharmacy faculty members so adequate guidance is available to future pharmacy educators.

    2014-11-01

    Although aphasia rehabilitation should include significant others, it is currently unknown how this recommendation is adopted in speech-language therapy practice. Speech-language therapists' (SLTs) experience of including significant others in aphasia rehabilitation is also understudied, yet a better understanding of clinical reality would be necessary to facilitate implementation of best evidence pertaining to family interventions. To explore the process through which SLTs work with significant others of people with aphasia in rehabilitation settings. Individual semi-structured interviews were conducted with eight SLTs who had been working with persons with aphasia in rehabilitation centres for at least 1 year. Grounded theory principles were applied in analysing interview transcripts. A theoretical model was developed representing SLTs' process of working with significant others of persons with aphasia in rehabilitation. Including significant others was perceived as challenging, yet a bonus to their fundamental patient-centred approach. Basic interventions with significant others when they were available included information sharing. If necessary, significant others were referred to social workers or psychologists or the participants collaborated with those professionals. Participants rarely and only under specific conditions provided significant others with language exercises or trained them to communicate better with the aphasic person. As a result, even if participants felt satisfied with their efforts to offer family and friends interventions, they also had unachieved ideals, such as having more frequent contacts with significant others. If SLTs perceived work with significant others as a feasible necessity, rather than as a challenging bonus, they could be more inclined to include family and friends within therapy with the aim to improve their communication with the person with aphasia. SLTs could also be more satisfied with their practice. In order to

    2016-09-01

    Full Text Available The paper examines the relationships between two different approaches to planning processes (participa- tive and non-participative and information flows within management control in companies. It augments the existing theoretical and empirical research by coupling management control and management infor- mation with participative planning, not only in operational but also in the strategic perspective. The re- sults presented in the paper stem from two consecutive studies, conducted between November 2010 and January 2012 and between November 2013 and January 2014. The studies comprised 397 and 179 Polish companies respectively. The authors formulated two hypotheses linking participative planning with upward and downward management information flows. The paper employed a quantitative approach, using the Spearman rank correlation analysis and hierarchical clustering using the Ward method, which enabled comparative analyses both in reference to various groups of companies included in particular research samples and over time. The results obtained showed the positive influence of participative plan- ning both on upward and downward information flows in enterprises. In particular, participative planning reduced information imbalances between top (the management and lower (employees of functional departments tiers in organisation structures.

    Delmas, R.; Serca, D.; Jambert, C.

    1997-01-01

    Nitrogen oxides are key compounds for the oxidation capacity of the troposphere. Their concentration depends on the proximity of sources because of their short atmospheric lifetime. An accurate knowledge of the distribution of their sources and sinks is therefore crucial. At the global scale, the dominant sources of nitrogen oxides - combustion of fossil fuel (about 50%) and biomass burning (about 20%) - are basically anthropogenic. Natural sources, including lightning and microbial activity in soils, represent therefore less than 30% of total emissions. Fertilizer use in agriculture constitutes an anthropogenic perturbation to the microbial source. The methods to estimate the magnitude and distribution of these dominant sources of nitrogen oxides are discussed. Some minor sources which may play a specific role in tropospheric chemistry such as NO x emission from aircraft in the upper troposphere or input from production in the stratosphere from N 2 O photodissociation are also considered

    Despite the social work profession's strengths orientation, research on its workforce tends to focus on problems (for example, depression, problem drinking, compassion fatigue, burnout). In contrast, this study explored ways in which social workers find joy in their work. The authors used an appreciative inquiry approach, semistructured interviews (N = 26), and a collaborative grounded theory method of analysis. Participants identified interpersonal (making connections and making a difference) and intrapersonal (making meaning and making a life) sources of joy and reflected significant personal initiative in the process of finding joy. The authors present findings regarding these intrapersonal sources of joy.

    Full Text Available Community participation is an important goal for people who have experienced homelessness. The aim of this study was to use the International Classification of Functioning, Disability and Health (ICF as a framework to examine factors associated with community participation among people who are homeless or recently housed through housing programs. Participants (n = 120 recruited from six housing placement and search programs completed measures of community participation (including productivity, social and leisure, and community-services-use domains, psychiatric and physical symptoms, functional limitations, and a demographic form. Multiple regression analyses were used to identify predictors of overall community participation and subdomain scores. Results suggested that cognitive and mobility limitations, relationship status, and housing status significantly predicted both overall participation and participation in productivity and social and leisure subdomains. Participants who were housed through housing programs, who had cognitive and mobility limitations, and who were single showed less community participation. The findings suggest that activity limitations and environmental and personal factors may need to be addressed in efforts to enhance community participation in this population.

    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 Three studies were carried out to examine whether trust in sources of information on technology is related to positive attitudes toward shale gas drilling. Factors we controlled for included: scientific knowledge, universalism and security as personal values, attitudes towards science, personal and group identity fusion, political views, and valence of the media information people received. We assumed hypothesis 1, that trust in the source of the information would be a significant predictor of positive attitudes toward shale gas, above and beyond other variables we controlled for (study 1. Also, we stated hypothesis 2, that trust in the source of information on technology in question would be related to more positive attitudes toward shale gas when more positive information is provided, and to more negative perception of gas drilling when less positive information is presented. Thus, we expected an interaction effect between trust and valence of information presented to participants (studies 2 and 3. Participants completed questionnaires in Poland (studies 1 and 2 and the USA (study 3. They where recruited from communities in regions where shale gas industry could potentially be developed (study 2 or has been developed (study 3. The results showed: (a a significant relationship between trust in negative information on shale gas and negative attitudes toward extraction; (b a significant interaction between trust and valence of information on shale gas. That is, trust in the source of information was related to more positive attitudes toward shale gas when a positive view is provided, and to more negative attitudes when undesirable information is presented.
