    In recent decades, there has been a burgeoning interest in the study of volunteering, and the number of publications devoted to volunteering has grown exponentially. In this chapter, we examine emerging theories and new directions in volunteering research.

    Separate literatures have related volunteering to health gains and income gains. We study the association between volunteering, income and health within one statistical framework. A state-of-the-art mediation analysis is conducted on data concerning the health, volunteering and sociodemographic characteristics of 42926 individuals within 29 European countries. We find that volunteering is positively associated to self-rated health. This association is partially mediated by household income. PMID:28273163

    Full Text Available The research is done in order to describe student’s attitudes on volunteering in sport. The sample consists of 231 students from Serbia, average age 21,06±3,12years. They were from eight colleges and faculties. For nominal and ordinal variables, frequencies were determined. Many of examined students have volunteering experiences. The results confirm that students believe that we live in a society which his generally thought only to its own benefit; they think that volunteering can not solve the problems in society; that people do not have enough experience with volunteering and people do not have time to volunteering; volunteering is for young people; in their family and among friends, there are no volunteers; everyone could be volunteer only if that wishes; do not believe that volunteering is a waste of time and it helps in future career. The prevalent number of students, regardless of the Faculty which they belong, rarely volunteered in areas outside of sport. Results also shows that students from sport faculties have less experience in volunteering in sport than students from other faculties, but this difference is not dramatic.

  4. Retired RNs: perceptions of volunteering.

    Science.gov (United States)

    Cocca-Bates, Katherine C; Neal-Boylan, Leslie

    2011-01-01

    A qualitative study was done to explore the perceptions of volunteering among retired registered nurses (RNs) in Kansas. Participants were volunteers in formal nursing roles or were using their nursing knowledge and experience in non-nursing roles, such as church work. Regardless of the type of volunteer position, retired RNs reported that they use what they have learned as nurses when they volunteer. Volunteering benefits include enhanced self-worth, intellectual stimulation, reduced social isolation, and opportunities to help others. Increased paperwork, new technology, difficulty finding nursing-specific volunteer opportunities, resistance from health care organizations, and a lack of respect for what these nurses know are challenges and barriers to volunteering. Retired RNs have accumulated years of clinical nursing experience and can be helpful to employed nurses. Health care organizations should launch targeted efforts to recruit and utilize retired RN volunteers. Health care professionals who care for older adults should recommend volunteering as a healthful endeavor.

Empirically we identify three channels for crowding out of voluntary labor. Firstly, an increase in public social expenditure decreases the probability that the individual will volunteer (fiscal crowding out). Secondly, a political c...

    2013-01-01

    The involvement of non-government organizations (NGOs) and support groups has helped strengthen public health services in addressing cancer care burden. Owing to the contribution of volunteers in cancer care, this article documents a qualitative study that examined challenges in attracting and retaining cancer care volunteers as part of the effort to develop a volunteer recruitment model. Data were collected through three focus group discussions involving 19 cancer support group members in Malaysia. Findings of the study revealed that mobility and locality appeared to be significant in Malaysian context, while the need for financial support and time flexibility are challenges faced by cancer support groups to attract and retain volunteers. The findings imply that cancer care initiatives can benefit from more local volunteers but at the same time these volunteers require flexibility and financial support to sustain their engagement.

    2007-05-01

    This study builds upon and extends the social-identity-based model of cooperation with the organization (T. R. Tyler, 1999; T. R. Tyler & S. L. Blader, 2000) to examine commitment and cooperative intent among fundraising volunteers. In Study 1, structural equation modeling indicated that pride and respect related to the intent to remain a volunteer with an organization, and that this relation was mediated primarily by normative organizational commitment. In Study 2, structural equation modeling indicated that the perceived importance of volunteer work was related to pride, that perceived organizational support related to the experience of respect, and that pride and respect mediated the relation between perceived importance and support on the one hand and organizational commitment on the other. Overall, the results suggest that volunteer organizations may do well to implement pride and respect in their volunteer policy, for instance to address the reliability problem (J. L. Pearce, 1993).

    Intensive experiences show and confirm that grid environments can be considered as the most promising way to solve several kinds of problems relating either to cooperative work especially where involved collaborators are dispersed geographically or to some very greedy applications which require enough power of computing or/and storage. Such environments can be classified into two categories; first, dedicated grids where the federated computers are solely devoted to a specific work through its end. Second, Volunteer grids where federated computers are not completely devoted to a specific work but instead they can be randomly and intermittently used, at the same time, for any other purpose or they can be connected or disconnected at will by their owners without any prior notification. Each category of grids includes surely several advantages and disadvantages; nevertheless, we think that volunteer grids are very promising and more convenient especially to build a general multipurpose distributed scalable enviro...

  15. Engaged anthropology and corporate volunteering

    Directory of Open Access Journals (Sweden)

    Natália Blahová

    2015-12-01

    Full Text Available The aim of this paper is to present engaged anthropology and its methodological tools with a specific perspective of the research field and the position of the researcher with regard to research subjects. The study focuses on corporate volunteering as one of the forms of collaboration between the non-profit and the private sectors seeking solutions to social problems and community development. Volunteering projects contribute to the interlinking of the knowledge, skills, experience and resources of corporate employees and the representatives of the non-profit or the public sector. It is a part of the philanthropic strategy of companies which are willing to present themselves as entities responsible towards the environment in which they run their business, and towards their employees, partners and customers. Engaged anthropology can bring, through its methodological tools, a new perspective of corporate volunteering. Community-based participatory research on the process of knowledge creation includes all partners on an equal basis and identifies their unique contribution to problem solution and community development.

    Claxton-Oldfield, Stephen; Hastings, Emily; Claxton-Oldfield, Jane

    2008-01-01

    A total of 50 nurses (hospital and home care) responded to a survey designed to measure: (1) their attitudes toward, and knowledge of, hospice palliative care volunteers; (2) the types of tasks they felt it was appropriate for volunteers to perform; and (3) how valuable they felt different members of the hospice palliative care team are. In addition, they were asked to respond to some open-ended questions (eg, "Do you feel that it is appropriate for hospice palliative care volunteers to know patient medical information?"). The nurses' responses to the "Attitude/Knowledge" part of the survey revealed that they generally held positive attitudes toward volunteers. The majority of the nurses felt that it was appropriate for volunteers to perform most of the tasks listed, except for hands-on patient care. Nurses rated the value of nurses, family members, doctors, and pharmacists significantly higher than volunteers. Fifty-three percent of the nurses felt that volunteers should know patient medical information, and 77% thought that volunteers should have the opportunity to provide input regarding patient care. Also, 75% of the nurses felt that volunteers made their jobs easier, and 56% felt that volunteers should be included in team meetings. When asked to list the topics covered in a hospice palliative care volunteer training program, 73% of the nurses indicated that they were not sure or did not know what topics were covered, indicating a lack of knowledge regarding volunteer training.

    2015-11-01

    This study investigates the interplay among religiosity, spirituality, value-expressive volunteer motivation, and volunteering. We examined religiosity and spirituality as predictors of value-expressive volunteer motivation and volunteering and whether religiosity moderated the relations between (a) spirituality and value-expressive volunteer motivation and (b) value-expressive volunteer motivation and volunteering. After applying multiple imputation procedures to data from the Wisconsin Longitudinal Study among participants 64-67 years old who survived beyond 2004 (N = 8,148), we carried out regression analyses to predict value-expressive volunteer motivation and volunteering from religiosity and spirituality controlling for demographic variables, physical, emotional, and cognitive health, health risk behaviors, and personality traits. Both religiosity and spirituality were significant (p religiosity were significant (p Religiosity amplified the relation between value-expressive volunteer motivation and volunteering (p .45). Religiosity may provide the way, and value-expressive volunteer motivation the will, to volunteer. The implications of our findings for the forecasted shortage of older volunteers are discussed. © The Author 2014.

    Full Text Available The hosting of the London 2012 Olympic Games was seen as an opportunity to harness the enthusiasm of the 70,000 volunteers involved and to provide a post-event volunteer legacy. A total of 77 individuals who had acted as volunteers in London 2012 were contacted approximately four years after the Games and agreed to complete a web-based open-ended survey. The participants were asked to indicate their level of current volunteering engagement and whether volunteering at the Games had an impact on their current volunteering levels. The study found that the London Olympics were the first volunteer experience for most of the volunteers who completed the survey, with the main motivation to volunteer being anything related to the Olympic Games. Just over half of the respondents are currently volunteering. Lack of time is shown to be the main barrier towards further volunteering commitment. Only half of respondents had been contacted by a volunteering scheme after London 2012. The implications of the findings for a potential volunteering legacy are then explored.

    Full Text Available Programmes targeting student volunteering and service learning are part of encouraging civic behaviour amongst young people. This article reports on a large scale international survey comparing volunteering amongst tertiary students at universities in Australia, Canada, New Zealand, the United Kingdom, and the United States of America. The data revealed high rates of student volunteering and the popularity of occasional or episodic volunteering. There were strong commonalities in student volunteering behaviour, motivations and benefits across the five Western predominately English-speaking countries. Altruism and self-orientated career motivations and benefits were most important to students; however volunteering and non-volunteering students differed in the relative value they attached to volunteering for CV-enhancement and social factors.

    Directory of Open Access Journals (Sweden)

    2008-07-01

    Full Text Available Nowadays, when the welfare state is a responsibility of the entire society, organizations in the private sector assume co-responsibility for social issues. They are also pressured by the challenges presented by technological advances and the globalization , involving new parameters and requirements for quality. In this context, the concept of Corporate Social Responsibility (RSC emerges as an option for solutions to the issues related to the company and the whole community. Among the actions of the RSC is the Corporate Volunteering-program, which aims to promote / encourage employes to do voluntary work. A central issue when talking about volunteering is the withdrawal of these (SILVA and FEITOSA, 2002; TEODÓSIO, 1999 and, in accordance with the Community Solidarity (1997, one of the possible causes for the withdrawal is the lack of clarity as to the motives and expectations that lead the person to volunteer themselves. This study uses qualitative research and triangulation of feedback from volunteers, coordinators of volunteers and social organizations, to present a framework from which it is possible to analyze the various motivations for the volunteer work. Key words: Corporate Volunteering program. Volunteering. Corporate social responsibility.

    In total, 120 British female hospice volunteers completed the NEO five-factor inventory (NEO-FFI) of Costa Jr and McCrae. The NEO-FFI measures the so-called big 5 personality traits of neuroticism, extraversion, openness, agreeableness, and conscientiousness. Compared to both American NEO-FFI norms for adult females and emerging British NEO-FFI norms for adult females, the hospice volunteers scored significantly lower, on average, in neuroticism and significantly higher, on average, in agreeableness and conscientiousness. No significant differences were found on any of the 5 traits between the British female hospice volunteers' scores and the NEO-FFI scores previously collected from a sample of Canadian female hospice palliative care volunteers. Implications for the recruitment of British hospice volunteers are discussed.

    Full Text Available The aim of this study was to test the possibility of predicting volunteer motives based on five-factor model of personality in a sample of 159 volunteers from Zagreb, Osijek and Split. Data was collected using IPIP-300 personality questionnaire and Volunteer Functions Inventory. Results indicate that Croatian volunteers are agreeable, conscientious, altruistic, dutiful, and moral persons with artistic interests. Their most salient motives for volunteering are understanding and values. Hierarchical regression analysis confirmed that the five-factor model personality traits independently predict 17% of protective motive variance, 12% of values motive, 18% of career motive, 10% of understanding motive, and 12% of enhancement motive. Social motive was not explained by personality traits.

    Science.gov (United States)

    Macrae, F A; Mackay, I R; Fraser, J R

    1989-03-20

    Research that involves healthy normal volunteers frequently is performed. This article examines ethical guide-lines for the recruitment of healthy volunteers in research projects. Ethical decisions on projects that are based on patient-volunteers or healthy normal volunteers should balance the risk to the volunteer and the collective benefit to the community. For healthy normal volunteers that risk should be minimal or trivial. Investigators should follow recruitment practices that avoid approaches to persons who are dependent upon them in some way, and should carry the day-to-day ethical responsibility even after institutional ethical approval has been granted. Pilot studies and self-experimentation readily can transgress ethical guide-lines. Compensation for mishaps or injuries that occur during research in which there is no question of negligence (for example, an unforeseeable reaction in a phase-1 drug trial) is an unresolved issue which should be addressed by the research community. It is recommended that action be taken to ensure that healthy volunteers who participate in approved research have redress in the rare event of an accident, whether this is a result of negligence, chance or misadventure. Hospitals/institutions or other bodies that sponsor research should extend their insurance to cover specifically such unforeseeable events in which there may be liability, and to have the facility for a payment of beneficence in the case of accidents in which liability cannot be established.

  13. Volunteering as a determinant of civil society

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Another prerequisite of volunteerism was the surge of Advantages Revolution in 2013-2014, and after it – the anti-terrorist operation in eastern Ukraine. In 2015 the aid organization in terms of ATO and internally displaced persons has increased directions volunteering. Important indicators of volunteering were high levels of involvement of Ukrainian philanthropy and consequently public confidence in voluntary organizations, qualitative growth of volunteerism, the founders of which were gradually included among the managerial elite Ukraine. At the same time, there are number of problems that discredit the work of volunteers and the idea of volunteering in general, for example, fraud volunteers and fake organizations. Moreover, the increased activity of the volunteer movement was caused by the internal crisis that led to the imbalance of public administration, lack of high-quality management decisions, lack of resource capabilities. Also it was caused by external factors, such as the need to participate in the organization of international events and conduct military operations against separatist groups in eastern Ukraine. So, volunteer activity gradually becomes an effective mechanism of self-organization of citizens.

  16. Becoming an Older Volunteer: A Grounded Theory Study

    Directory of Open Access Journals (Sweden)

    Janet Witucki Brown

    2011-01-01

    Full Text Available This Grounded Theory study describes the process by which older persons “become” volunteers. Forty interviews of older persons who volunteered for Habitat for Humanity were subjected to secondary content analysis to uncover the process of “becoming” a volunteer. “Helping out” (core category for older volunteers occurs within the context of “continuity”, “commitment” and “connection” which provide motivation for volunteering. When a need arises, older volunteers “help out” physically and financially as health and resources permit. Benefits described as “blessings” of volunteering become motivators for future volunteering. Findings suggest that older volunteering is a developmental process and learned behavior which should be fostered in older persons by personally inviting them to volunteer. Intergenerational volunteering projects will allow older persons to pass on knowledge and skills and provide positive role modeling for younger volunteers.

  1. Holding on to what you have got: keeping hospice palliative care volunteers volunteering.

    Science.gov (United States)

    Claxton-Oldfield, Stephen; Jones, Richard

    2013-08-01

    In all, 119 hospice palliative care volunteers from 3 community-based hospice programs completed the Volunteer Retention Questionnaire (VRQ), a 33-item survey designed for this study. The VRQ asks volunteers to rate the importance of each item to their decision to continue volunteering. The items that received the highest mean importance ratings included enjoying the work they do, feeling adequately prepared/trained to perform their role, and learning from their patients' experiences/listening to their patients' life stories. Being recognized (eg, pins for years of service or being profiled in the hospice newsletter), receiving phone calls/cards from their volunteer coordinator on special occasions, and being reimbursed for out-of-pocket expenses were among the items that received the lowest mean importance ratings. Suggestions for improving volunteer retention are provided.

    This study examined the motivations for volunteering of hospice volunteers in France. In addition, their levels of death anxiety and empathy were measured and compared with those of French non-hospice volunteers and non-volunteers. Three questionnaires-the Inventory of Motivations for Hospice Palliative Care Volunteerism (IMHPCV), the Templer/McMordie Death Anxiety Scale, and the Interpersonal Reactivity Index-were sent via an Internet link to 2 hospice volunteer associations and to non-hospice volunteers and non-volunteers (only the hospice volunteers received the IMHPCV). Altruistic motives had the most influence on the respondents' decision to become a hospice volunteer. French hospice volunteers scored significantly lower on 3 categories of motives on the IMHPCV compared to a sample of Canadian hospice palliative care volunteers (study 2), suggesting that cultural differences may be involved. No significant differences were found in levels of death anxiety or empathy between the 3 groups of respondents of the study.

    2014-01-01

    Full Text Available Volunteer tourists are motivated to participate in volunteer programs due to their need to ‘do something different’, ‘see another culture’ and ‘to escape’, amongst others. The research aims to determine the internal and external factors that motivate individuals to participate in the Tsau! Global White Lion Protection Trust’s (GWLPT volunteer program. Maslow’s theory of human motivation and Frankl’s study of human behaviour are used to explore intrinsic factors whereas extrinsic or macro environmental factors of influence are also investigated. A mixed method approach with focus group discussions and an online survey is followed. A background to the volunteer program is presented with the activities available to volunteers. The key findings indicate that most volunteers are young females that volunteer for a minimum of two weeks; are internally motivated to ‘give back and be useful’ and ‘to work with the white lions’ for the purpose of self-actualisation. External motivation is mainly social in terms of concern about the well-being of the lions, and South Africa being an economically affordable destination. The GWLPT strives to fulfil the needs of volunteers, especially intrinsic needs associated with self-actualisation and self-transcendence.

    Full Text Available Understanding personality characteristics of volunteers are important for their recruitment and retention in sport associations. This study compared self-concept as a personality characteristic between volunteer and non-volunteer students in sport associations. The method of this research was survey and descriptive. The statistical population consisted of volunteer and non-volunteer students in sport associations of Iran universities. Two hundred and fifty two students (120 volunteers and 132 non-volunteers from 10 universities were selected as subjects by using random clustered sampling method. Pyryt and Mandaglio Self Perceived Survey (PMSPS was used to collect the data. The content and face reliability of questionnaire was checked and confirmed. Cronbach’s alpha coefficient was used to test the reliability of the questionnaire (alfa=0.90. Independent t test and U Mann-Whitney test were used for comparison of the factors between volunteers and non-volunteers. Findings of this study indicated that there was a significant difference between volunteer and non-volunteer students in social and athletic self-concept. The mean of scientific and value factors were higher in volunteers than non-volunteers, however, they were not statistically significant. We concluded that the nature of sport (active and sport volunteering (social encourage students who have higher self-concept for volunteering. Moreover, the characteristics of sport associations can increase self-concept in sport volunteers.

  11. Volunteered Cloud Computing for Disaster Management

    Science.gov (United States)

    Evans, J. D.; Hao, W.; Chettri, S. R.

    2014-12-01

    Disaster management relies increasingly on interpreting earth observations and running numerical models; which require significant computing capacity - usually on short notice and at irregular intervals. Peak computing demand during event detection, hazard assessment, or incident response may exceed agency budgets; however some of it can be met through volunteered computing, which distributes subtasks to participating computers via the Internet. This approach has enabled large projects in mathematics, basic science, and climate research to harness the slack computing capacity of thousands of desktop computers. This capacity is likely to diminish as desktops give way to battery-powered mobile devices (laptops, smartphones, tablets) in the consumer market; but as cloud computing becomes commonplace, it may offer significant slack capacity -- if its users are given an easy, trustworthy mechanism for participating. Such a "volunteered cloud computing" mechanism would also offer several advantages over traditional volunteered computing: tasks distributed within a cloud have fewer bandwidth limitations; granular billing mechanisms allow small slices of "interstitial" computing at no marginal cost; and virtual storage volumes allow in-depth, reversible machine reconfiguration. Volunteered cloud computing is especially suitable for "embarrassingly parallel" tasks, including ones requiring large data volumes: examples in disaster management include near-real-time image interpretation, pattern / trend detection, or large model ensembles. In the context of a major disaster, we estimate that cloud users (if suitably informed) might volunteer hundreds to thousands of CPU cores across a large provider such as Amazon Web Services. To explore this potential, we are building a volunteered cloud computing platform and targeting it to a disaster management context. Using a lightweight, fault-tolerant network protocol, this platform helps cloud users join parallel computing projects

    Einstein@Home aggregates the computer power of hundreds of thousands of volunteers from 192 countries to mine large data sets. It has now found a 40.8-hertz isolated pulsar in radio survey data from the Arecibo Observatory taken in February 2007. Additional timing observations indicate that this pulsar is likely a disrupted recycled pulsar. PSR J2007+2722’s pulse profile is remarkably wide with emission over almost the entire spin period; the pulsar likely has closely aligned magnetic and spin axes. The massive computing power provided by volunteers should enable many more such discoveries.

    Since a couple of years, a team at CERN and partners from the Citizen Cyberscience Centre (CCC) have been working on a project that enables general physics simulation programs to run in a virtual machine on volunteer PCs around the world. The project uses the Berkeley Open Infrastructure for Network Computing (BOINC) framework. Based on CERNVM and the job management framework Co-Pilot, this project was made available for public beta-testing in August 2011 with Monte Carlo simulations of LHC physics under the name “LHC@home 2.0” and the BOINC project: “Test4Theory”. At the same time, CERN's efforts on Volunteer Computing for LHC machine studies have been intensified; this project has previously been known as LHC@home, and has been running the “Sixtrack” beam dynamics application for the LHC accelerator, using a classic BOINC framework without virtual machines. CERN-IT has set up a BOINC server cluster, and has provided and supported the BOINC infrastructure for both projects. CERN intends to evolve the setup into a generic BOINC application service that will allow scientists and engineers at CERN to profit from volunteer computing. This paper describes the experience with the two different approaches to volunteer computing as well as the status and outlook of a general BOINC service.

    Schlesinger, Torsten; Nagel, Siegfried

    2013-01-01

    This article analyses the conditions influencing volunteering in sports clubs. It focuses not only on individual characteristics of volunteers but also on the corresponding structural conditions of sports clubs. It proposes a model of voluntary work in sports clubs based on economic behaviour theory. The influences of both the individual and context levels on the decision to engage in voluntary work are estimated in different multilevel models. Results of these multilevel analyses indicate that volunteering is not just an outcome of individual characteristics such as lower workloads, higher income, children belonging to the sports club, longer club memberships, or a strong commitment to the club. It is also influenced by club-specific structural conditions; volunteering is more probable in rural sports clubs whereas growth-oriented goals in clubs have a destabilising effect.

    2007-01-01

    The goal of this study was to examine the impact of hospice palliative care work on volunteers' lives. In-depth interviews were conducted with 23 direct-patient care volunteers. More than half of the volunteers became involved in hospice palliative care because of their own experiences with family members and/or friends who have died. Most of the volunteers reported that they were different now or had changed in some way since they have been volunteering (e.g., they had grown in some way, have learned how to keep things in perspective). In addition, most of the volunteers felt that their outlook on life had changed since they started volunteering (e.g., they were more accepting of death, and they learned the importance of living one day at a time). Volunteers reported doing a number of different things to prevent compassion fatigue or burnout (e.g., reading a book, listening to music, talking to others, and taking time off from volunteering). Most of the volunteers said that they would tell anyone who might be thinking of volunteering in hospice palliative care that it is a very rewarding activity and/or that they should try it. Finally, many of the volunteers offered suggestions for doing things differently in their programs.

    Volunteers have been present in health care settings for centuries. However, there is little empirical evidence regarding the impact that volunteers make on hospital performance. Since the 1990s, hospitals in the United States have had a great deal of pressure to produce high-quality care at minimum expense. These pressures have enhanced the benefits of using volunteers in a hospital setting. This study utilized multiple regression analysis to explore the impact of the use of volunteers and the level of professionalism of volunteer programs on cost effectiveness and patient satisfaction in hospitals. Hospitals throughout the state of Florida were invited to participate in the study by completing a brief questionnaire about their volunteer programs. Performance indicators of volunteer cost savings and patient satisfaction scores for 50 Florida hospitals were analyzed using data sets from the American Hospital Association and Agency for Health Care Administration along with data obtained from a questionnaire. Results indicate that the use of volunteers offers significant cost savings to hospitals and enhances patient satisfaction scores. Larger volunteer programs appear to enhance patient satisfaction while containing costs. Future research opportunities related to the impact of volunteers and volunteer professionalism on other hospital performance measures are suggested.

    2010-04-01

    These studies examined how the practice of accounting for one's time-so that work can be billed or charged to specific clients or projects-affects the decision to allocate time to volunteer activities. Using longitudinal data collected from law students transitioning to their first jobs, Study 1 showed that exposure to billing time diminished individuals' willingness to volunteer, even after controlling for attitudes about volunteering held before entering the workforce as well as the individual's specific opportunity costs of volunteering time. Studies 2-5 experimentally manipulated billing time and confirmed its causal effect on individuals' willingness to volunteer and actual volunteering behavior. Study 5 showed that the effect of exposure to billing time on volunteering occurred above and beyond any effects on general self-efficacy or self-determination. Individual differences moderated the effects of billing, such that people who did not value money as much were less affected.

  10. Widely Assumed but Thinly Tested: Do Employee Volunteers' Self-Reported Skill Improvements Reflect the Nature of Their Volunteering Experiences?

    2016-01-01

    An increasing number of companies use corporate volunteering programs (CVPs) to support and coordinate their employees' efforts to serve their communities. Among the most frequently touted benefits of such programs to sponsoring companies and employee volunteers alike is the opportunities for employees to develop tangible work-related skills through their volunteering activities. Evidence for skill development through volunteering, however, is mostly limited to the expressed beliefs of corporate leaders and employee volunteers. This study was designed to contribute to this largely anecdotal literature by testing hypotheses about the extent to which employee volunteers' self-reported skill development reflects the characteristics of the volunteers and their volunteering experiences. Study participants were 74 employee volunteers who completed a service apprenticeship managed by a U.S.-based nonprofit called Citizen Schools that partners with middle schools to extend the learning day with a combination of academic support, enrichment, and youth development activities. Data were obtained via the nonprofit's records, and surveys completed by employee volunteers before and after their service experience, including measures used to assess self-reported improvements in each of 10 work-related skills: communicating performance expectations, leadership, mentorship, motivating others, project management, providing performance feedback, public speaking and presenting, speaking clearly, teamwork, and time management. Support was found for several hypothesized effects suggesting that employees who practiced specific skills more often during their volunteering experience reported greater improvements in those skills. Improvements in some skills were higher among employee volunteers who completed a greater number of pre-volunteering preparation courses, and the effects of preparation courses were moderated by the employee volunteers' self-efficacy about improving their work

    In the present study, we combined components of the theory of planned behavior and the functional approach to predict the social sector volunteering intention of nonvolunteers (N = 513). Moreover, we added a new other-oriented "social justice function" to the Volunteer Functions Inventory of Clary and colleagues (1998), which contains mainly self-oriented functions. We distinguished the social justice function from the other five measured volunteer functions in confirmatory factor analysis, and showed its incremental validity in predicting intention to volunteer beyond established constructs such as self-efficacy, subjective norm, and the five volunteer functions. This study suggests that emphasizing potential social justice improvements by means of volunteering may attract new volunteers.

    The objective of this research study was to conduct a systematic review of the research on volunteers using Clary et al.’s VFI (1998). A total of 48 research studies including 67 independent samples met eligibility criteria. The total sample of the studies analyzed ranged from 20375 to 21988 participants, depending on the motivation analyzed. The results show that the Values factor obtained the highest mean score, both overall and in each type of volunteering, whereas the lowest scores were for the Career and Enhancement factors. Studies conducted with samples with a mean age under 40 years obtain higher scores on Career and Understanding scales when compared to studies in older samples. The group of studies with less than 50% women yield higher mean scores on the Social scale than studies with more than 50% women in the sample. All the scales show reliability coefficients between .78 and .84. Only eight of the articles provide data on the reliability of the scale with a mean value of .90. Of the 26 studies that performed factor analysis, 18 confirmed the original structure of six factors.

  14. Evolutionary stability in the asymmetric volunteer's dilemma.

    Directory of Open Access Journals (Sweden)

    Jun-Zhou He

    Full Text Available It is often assumed that in public goods games, contributors are either strong or weak players and each individual has an equal probability of exhibiting cooperation. It is difficult to explain why the public good is produced by strong individuals in some cooperation systems, and by weak individuals in others. Viewing the asymmetric volunteer's dilemma game as an evolutionary game, we find that whether the strong or the weak players produce the public good depends on the initial condition (i.e., phenotype or initial strategy of individuals. These different evolutionarily stable strategies (ESS associated with different initial conditions, can be interpreted as the production modes of public goods of different cooperation systems. A further analysis revealed that the strong player adopts a pure strategy but mixed strategies for the weak players to produce the public good, and that the probability of volunteering by weak players decreases with increasing group size or decreasing cost-benefit ratio. Our model shows that the defection probability of a "strong" player is greater than the "weak" players in the model of Diekmann (1993. This contradicts Selten's (1980 model that public goods can only be produced by a strong player, is not an evolutionarily stable strategy, and will therefore disappear over evolutionary time. Our public good model with ESS has thus extended previous interpretations that the public good can only be produced by strong players in an asymmetric game.

  15. Growing Your Career through Volunteering and Leadership

    From giving your first paper at a scientific meeting to chairing committees that make multi-million dollar decisions, scientific organizations provide critical opportunities for growing your career. Many organizations support student activities by providing travel grants and fellowships - an important first step towards joining the larger scientific community. Beyond these standard opportunities, organizations also provide opportunities for students interested in gaining leadership experience, a skill not typically acquired in graduate science programs. For example, the Consortium for Leadership's Schlanger Ocean Drilling Fellowship provides research funds to graduate students, but also introduces the fellows to the communication skills needed to become successful members of their scientific community. Beyond student opportunities, volunteering provides mid-career and established scientists further experience in leadership. Opportunities exist in advising government science policy, guiding large-scale research programs, organizing large scientific meetings, and serving on non-profit boards. The variety of volunteer and leadership opportunities that are available give scientists at all stages of their career a chance to expand and diversify their experience, leading to new successes.

    Since a couple of years, a team at CERN and partners from the Citizen Cyberscience Centre (CCC) have been working on a project that enables general physics simulation programs to run in a virtual machine on volunteer PCs around the world. The project uses the Berkeley Open Infrastructure for Network Computing (BOINC) framework. Based on CERNVM and the job management framework Co-Pilot, this project was made available for public beta-testing in August 2011 with Monte Carlo simulations of LHC physics under the name "LHC@home 2.0" and the BOINC project: "Test4Theory". At the same time, CERN's efforts on Volunteer Computing for LHC machine studies have been intensified; this project has previously been known as LHC@home, and has been running the "Sixtrack" beam dynamics application for the LHC accelerator, using a classic BOINC framework without virtual machines. CERN-IT has set up a BOINC server cluster, and has provided and supported the BOINC infrastructure for both projects. CERN intends to evolve the setup i...

    State water quality monitoring has been augmented by volunteer monitoring programs throughout the United States. Although a significant effort has been put forth by volunteers, questions remain as to whether volunteer data are accurate and can be used by regulators. In this study, typical volunteer water quality measurements from laboratory and environmental samples in Iowa were analyzed for error and bias. Volunteer measurements of nitrate+nitrite were significantly lower (about 2-fold) than concentrations determined via standard methods in both laboratory-prepared and environmental samples. Total reactive phosphorus concentrations analyzed by volunteers were similar to measurements determined via standard methods in laboratory-prepared samples and environmental samples, but were statistically lower than the actual concentration in four of the five laboratory-prepared samples. Volunteer water quality measurements were successful in identifying and classifying most of the waters which violate United States Environmental Protection Agency recommended water quality criteria for total nitrogen (66%) and for total phosphorus (52%) with the accuracy improving when accounting for error and biases in the volunteer data. An understanding of the error and bias in volunteer water quality measurements can allow regulators to incorporate volunteer water quality data into total maximum daily load planning or state water quality reporting. ?? 2010 American Chemical Society.

    2014-12-01

    Volunteering is presumed to confer health benefits, but interventions to encourage older adults to volunteer are sparse. Therefore, a randomized controlled trial with 280 community-dwelling older German adults was conducted to test the effects of a theory-based social-cognitive intervention against a passive waiting-list control group and an active control intervention designed to motivate physical activity. Self-reports of weekly volunteering minutes were assessed at baseline (5 weeks before the intervention) as well as 2 and 6 weeks after the intervention. Participants in the treatment group increased their weekly volunteering minutes to a greater extent than participants in the control groups 6 weeks after the intervention. We conclude that a single, face-to-face group session can increase volunteering among older community-dwelling adults. However, the effects need some time to unfold because changes in volunteering were not apparent 2 weeks after the intervention.

    2010-11-01

    Previous studies have demonstrated that functional limitations increase, and organizational volunteering decreases, the risk of mortality in later life. However, scant attention has been paid to investigating the joint effect of functional limitations and organizational volunteering on mortality. Accordingly, we tested the hypothesis that volunteering moderates the relation between functional limitations and risk of mortality. This prospective study used baseline survey data from a representative sample of 916 non-institutionalized adults 65 years old and older who lived in the continental United States. Data on mortality were extracted six years later from the National Death Index. Survival analyses revealed that functional limitations were associated with an increased risk of dying only among participants who never or almost never volunteered, suggesting that volunteering buffers the association between functional limitations and mortality. We conclude that although it may be more difficult for older adults with functional limitations to volunteer, they may receive important benefits from doing so.

    The procedures in the selection, training and supervision of 10 nonprofessional volunteers, to provide direct therapeutic crisis services to patients in a Suicide Prevention Center are described. One year's experience indicates a high degree of proficiency achieved by the volunteer in the handling of suicidal crises. The volunteers' reactions to the program are reported. Significant problems for the agency emerged in reference to precipitous increase in size of staff communication, and for the volunteer, in stimulation of problems of identity and selfconcept. The comments are limited to agency situations involving the use of nonprofessional volunteers in regular collaboration with a professional staff. Other models, such as entirely volunteer staffed groups, must be evaluated separately.

    There is a growing number of community first responder (CFR) groups in the UK who provide emergency care in their local communities. To understand why people volunteer for, and continue to be active in CFR groups. Qualitative study, using focus groups of CFRs. Five focus groups were conducted, with a total of 35 participants. Ideas of altruism and a sense of community were found to be important to volunteers, though motives were complex and individual. Many volunteers had some sort of prior experience relevant to the CFR role, either as health professionals or first-aiders. Though volunteers' motives had some commonalities with the limited literature, there were issues that were unique to the CFR context. The flexibility and autonomy of CFR volunteering was particularly attractive to volunteers. It remains to be seen how sustainable the CFR model is.

  7. A Systems Perspective on Volunteered Geographic Information

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Volunteered geographic information (VGI is geographic information collected by way of crowdsourcing. However, the distinction between VGI as an information product and the processes that create VGI is blurred. Clearly, the environment that influences the creation of VGI is different than the information product itself, yet most literature treats them as one and the same. Thus, this research is motivated by the need to formalize and standardize the systems that support the creation of VGI. To this end, we propose a conceptual framework for VGI systems, the main components of which—project, participants, and technical infrastructure—form an environment conducive to the creation of VGI. Drawing on examples from OpenStreetMap, Ushahidi, and RinkWatch, we illustrate the pragmatic relevance of these components. Applying a system perspective to VGI allows us to better understand the components and functionality needed to effectively create VGI.

    Using the concepts in the Fogg Behavioral Model, 37 volunteers aged 50 and older described their preparation for intensive volunteering with faith-based organizations. Their multistage preparation process included decision points where respondents needed to choose whether to drop out or continue preparation. Ability was a stronger determinant of serving than motivation, particularly in terms of health and finances. This model can facilitate understanding of the barriers to volunteering and aid organizations in tailoring support at crucial points for potential older volunteers in intensive service.

    Social networking sites (SNSs) provide a unique social venue to engage the young generation in philanthropy through their networking capabilities. An integrated model that incorporates social capital into the Theory of Reasoned Action is developed to explain volunteer behavior through social networks. As expected, volunteer behavior was predicted by volunteer intention, which was influenced by attitudes and subjective norms. In addition, social capital, an outcome of the extensive use of SNSs, was as an important driver of users' attitude and subjective norms toward volunteering via SNSs.

    Lysergic acid diethylamide (LSD) has a history of use as a psychotherapeutic aid in the treatment of mood disorders and addiction, and it was also explored as an enhancer of mind control. The present study sought to test the effect of LSD on suggestibility in a modern research study. Ten healthy volunteers were administered with intravenous (i.v.) LSD (40-80 μg) in a within-subject placebo-controlled design. Suggestibility and cued mental imagery were assessed using the Creative Imagination Scale (CIS) and a mental imagery test (MIT). CIS and MIT items were split into two versions (A and B), balanced for 'efficacy' (i.e. A ≈ B) and counterbalanced across conditions (i.e. 50 % completed version 'A' under LSD). The MIT and CIS were issued 110 and 140 min, respectively, post-infusion, corresponding with the peak drug effects. Volunteers gave significantly higher ratings for the CIS (p = 0.018), but not the MIT (p = 0.11), after LSD than placebo. The magnitude of suggestibility enhancement under LSD was positively correlated with trait conscientiousness measured at baseline (p = 0.0005). These results imply that the influence of suggestion is enhanced by LSD. Enhanced suggestibility under LSD may have implications for its use as an adjunct to psychotherapy, where suggestibility plays a major role. That cued imagery was unaffected by LSD implies that suggestions must be of a sufficient duration and level of detail to be enhanced by the drug. The results also imply that individuals with high trait conscientiousness are especially sensitive to the suggestibility-enhancing effects of LSD.

  4. Leveraging Telehealth to Bring Volunteer Physicians Into Underserved Communities.

    2016-11-28

    Many disadvantaged communities lack sufficient numbers of local primary care and specialty physicians. Yet tens of thousands of physicians, in particular those who are retired or semiretired, desire meaningful volunteer opportunities. Multiple programs have begun to use telehealth to bridge the gap between volunteer physicians and underserved patients. In this brief, we describe programs that are using this model and discuss the promise and pitfalls. Physician volunteers in these programs report that the work can be fulfilling and exciting, a cutting-edge yet convenient way to remain engaged and contribute. Given the projected shortfall of physicians in the United States, recruiting retired and semiretired physicians to provide care through telehealth increases the total supply of active physicians and the capacity of the existing workforce. However, programs typically use volunteers in a limited capacity because of uncertainty about the level and duration of commitment. Acknowledging this reality, most programs only use volunteer physicians for curbside consults rather than fully integrating them into longitudinal patient care. The part-time availability of volunteers may also be difficult to incorporate into the workflow of busy safety net clinics. As more physicians volunteer in a growing number of telehealth programs, the dual benefits of enriching the professional lives of volunteers and improving care for underserved communities will make further development of these programs worthwhile.

    2011-01-01

    Full Text Available Ireland has a longstanding history of diverse volunteer action (Volunteering Ireland, 2010a. Ireland’s current economic recession has impacted on the community and voluntary sector, with frequent contraction in staff numbers and incomes, and increasing reliance on volunteer participation (Harvey, 2012. This study utilised social capital theory to garner a phenomenological understanding of the contribution of volunteering to perceived social capital amongst Irish volunteers and host organisation representatives. A convenience sample of 28 participants (17 volunteers and 11 organisation representatives was interviewed. A shift in personal and social definitions of volunteering were described, with informal volunteering increasingly replaced by structured, formalized and regulated volunteer placements. Volunteers described their experiences as contributing to increased personal well being and sense of purpose, development of friendships and meeting new people. The volunteer participants identified volunteering activity as a specified community need, providing work related experiences, fulfillment in free time and opportunity for up-skilling. Integration of volunteers into the organisation’s workforce was described as dependent on duration, intensity of interaction and scope of volunteer contributions. Power differentials and a lack of trust between volunteers and staff, was described, as was a lack of volunteer recognition staff. Subsequently, some volunteers identified and aligned themselves within the wider social volunteer network rather than their host organisation. The research reflected an emergent consumerist approach to volunteering and underscores the need to preserve informal social networks of community volunteers, alongside the development of more formalized work specific routes for volunteering in Ireland.

    2014-01-01

    This paper studies English training for student volunteers at large scale sports events with a comprehensive investigation of the undergraduate student volunteers from Capital University of Physical Education who have taken part in large scale sports events. By examining the current volunteer training situation, the author finds that there is a sever lack of professional and system-atical English training for student volunteers at large scale sports events. The study shows focusing on sports events knowledge and requirements of the volunteers’specific job is crucial to the service level of the volunteers. The study concludes that the problem can be solved by developing new course books, innovating new flexible training methods, and offering more comprehensive training content. The recommended training methods include intensive group training, computer aided teaching, task training and on-the-spot training to make them fit their work soon.

    2016-01-01

    This study is one of the few that has compared volunteers' professional quality of life (PQL), which includes secondary traumatic stress (STS), burnout, and compassion satisfaction (CS), to those of professional caregivers. In addition, the research compared the ethical behavior of volunteers with that of professional therapists and examined the connection between years of experience, ethical behavior, and PQL. One hundred eighty-three volunteers and professional caregivers filled out a sociodemographic questionnaire, an Ethical Behavior Questionnaire and the Professional Quality of Life (ProQOL) questionnaire. The results indicated that professional caregivers report lower levels of STS and burnout, and higher levels of CS and ethical behavior compared with volunteer caregivers. Moreover, the findings suggest that ethical behavior correlates with STS, burnout, and CS. Ethical behavior has a protective value for mental health caregivers. The discussion emphasizes the value of a professional code of ethics and ethical training for professional and volunteering caregivers.

    The aim of this study was to explore the impact that using augmentative and alternative communication (AAC) had on the experiences of 24 adults with lifelong disabilities who worked as volunteers. This research forms part of a larger qualitative study of volunteering amongst adults who use AAC. Based on in-depth interviews and grounded theory analysis, the results indicate that communication is central to successful volunteering and, in particular, that access to AAC has the potential to provide valuable support to individuals with complex communication needs who want to volunteer. However, a number of barriers must be addressed in order for this potential to be achieved. Strategies for promoting and supporting adults who use AAC and want to volunteer are discussed.

    2010-01-01

    The purpose of this study is to use a nationally representative sample of older adults in the United States to investigate the effect gender and religiosity has on volunteer behavior in later life. This study looks specifically at the gender and religious differences associated with volunteering in later life. Accounting for gender and religious differences, more specifically, this study examines the assumption that older women are more likely to volunteer in later life as opposed to men, and that gender is a better predictor than being religious for the likelihood of occupying a volunteer role in later life. This study poses questions about the differences in gender and religiosity associated with volunteering in later life; the results indicate there is more work to be done as we conduct research that is clearer about how volunteerism and religiosity are measured in relation to gender, and the overall impact these differences have for older women and their respective communities.

    2016-06-01

    This article explores the relationships between municipality features and volunteering by older adults. In the literature, strong evidence exists of the influence of place on older people's health. However, the question how neighborhoods and municipalities promote or hinder volunteer participation remains under-explored. Data for the research are derived from the Belgian Aging Studies. We estimate logistic multilevel models for older individuals' engagement in volunteering across 141 municipalities in Belgium (N = 67,144). Analysis shows that neighborhood connectedness, neighborhood satisfaction, home ownership, and presence of services predict voluntary engagement at older ages. The findings support that perceptions and quality of social resources that relate to neighborhoods may be important factors to explain volunteering among older adults. Moreover, the findings suggest that volunteering in later life must be considered within a broader framework.

    Science.gov (United States)

    Volunteered geographic information (VGI) can be used to identify public valuation of ecosystem services in a defined geographic area using photos as a representation of lived experiences. This method can help researchers better survey and report on the values and preferences of stakeholders involved in rehabilitation and revitalization projects. Current research utilizes VGI in the form of geotagged social media photos from three platforms: Flickr, Instagram, and Panaramio. Social media photos have been obtained for the neighborhoods next to the St. Louis River in Duluth, Minnesota, and are being analyzed along several dimensions. These dimensions include the spatial distribution of each platform, the characteristics of the physical environment portrayed in the photos, and finally, the ecosystem service depicted. In this poster, we focus on the photos from the Irving and Fairmount neighborhoods of Duluth, MN to demonstrate the method at the neighborhood scale. This study demonstrates a method for translating the values expressed in social media photos into ecosystem services and spatially-explicit data to be used in multiple settings, including the City of Duluth’s Comprehensive Planning and community revitalization efforts, habitat restoration in a Great Lakes Area of Concern, and the USEPA’s Office of Research and Development.

  20. Education and Outreach for Volunteer Planetary Defense

    2016-12-01

    When a large meteor exploded over Chelyabinsk in 2013, people saw the bright flash and rushed to windows. Then the blast wave hit and many were injured by flying glass fragments. Education about airbursts might have reduced the casualties. Education and Public Outreach (EPO) can also be important in broadening public involvement in preparations for dealing with cosmic hazards. Amateur astronomers have an important role in discovering potentially hazardous asteroids and comets, and also in making follow-up observations after discovery. This is especially important for Southern Hemisphere observing sites where professional observers are relatively few. The Planetary Society makes small Shoemaker grants to aid amateur astronomers in this work. Much more could be done if educators, students and the general public were aware of the opportunity and the need. Beyond this, public engagement is essential to raise and maintain support for active agencies, including the UN-sponsored International Asteroid Warning Network (IAWN) and Space Mission Planning Advisory Group (SMPAG). This paper will describe and advocate EPO efforts in support of these and other Volunteer Planetary Defense activities.

  1. Prediction of psilocybin response in healthy volunteers.

    Directory of Open Access Journals (Sweden)

    Erich Studerus

    Full Text Available Responses to hallucinogenic drugs, such as psilocybin, are believed to be critically dependent on the user's personality, current mood state, drug pre-experiences, expectancies, and social and environmental variables. However, little is known about the order of importance of these variables and their effect sizes in comparison to drug dose. Hence, this study investigated the effects of 24 predictor variables, including age, sex, education, personality traits, drug pre-experience, mental state before drug intake, experimental setting, and drug dose on the acute response to psilocybin. The analysis was based on the pooled data of 23 controlled experimental studies involving 409 psilocybin administrations to 261 healthy volunteers. Multiple linear mixed effects models were fitted for each of 15 response variables. Although drug dose was clearly the most important predictor for all measured response variables, several non-pharmacological variables significantly contributed to the effects of psilocybin. Specifically, having a high score in the personality trait of Absorption, being in an emotionally excitable and active state immediately before drug intake, and having experienced few psychological problems in past weeks were most strongly associated with pleasant and mystical-type experiences, whereas high Emotional Excitability, low age, and an experimental setting involving positron emission tomography most strongly predicted unpleasant and/or anxious reactions to psilocybin. The results confirm that non-pharmacological variables play an important role in the effects of psilocybin.

    The relationships among beliefs about volunteerism, volunteering intention, volunteering behavior, and purpose in life were examined in this study. A total of 5,946 participants completed a series of scales, including the Revised Personal Functions of Volunteerism Scale, Volunteering Intention Scale, and Purpose in Life Scale. The results showed that participants whose purpose in life had different levels also had varied prosocial beliefs about volunteerism, volunteering intention, and volunteering behavior. Purpose in life was associated more strongly with prosocial value function than with other types of beliefs (except understanding function). When different beliefs are grouped, the correlation between purpose in life and other-serving beliefs was higher than that between purpose in life and self-serving beliefs. Purpose in life was also associated with volunteering intention and behavior. Path analyses showed that purpose in life predicted volunteering behavior via beliefs and intention. While other-serving beliefs predicted volunteering behavior directly, self-serving beliefs did not have such direct effect.

    The purpose of this study was to assess personality traits, psychological fitness, and hardiness among conscript soldiers volunteering for international missions (n = 146), by comparing them with conscripts from the same year class and unit who did not apply for international missions (n = 275). The sample consisted of all mandatory enlisted soldiers assigned to a supply and maintenance regiment. There were no demographic differences between the groups. The volunteers reported greater stress tolerance, concern for others, extraversion, and self-confidence than the non-volunteers. There were no differences between the groups in orderliness, temper instability, or independence. Volunteers repeatedly reported greater psychological fitness for military missions and greater hardiness over the period of military service compared to the non-volunteers.

    2014-02-01

    This systematic review aims to examine the differences and similarities between the various types of volunteer mentoring (befriending, mentoring and peer support) and to identify the benefits for carers and volunteers. Literature searching was performed using 8 electronic databases, gray literature, and reference list searching of relevant systematic reviews. Searches were carried out in January 2013. Four studies fitted the inclusion criteria, with 3 investigating peer support and 1 befriending for carers. Quantitative findings highlighted a weak but statistically significant (P =.04) reduction in depression after 6 months of befriending. Qualitative findings highlighted the value carers placed on the volunteer mentors' experiential similarity. Matching was not essential for the development of successful volunteer mentoring relationships. In conclusion, the lack of need for matching and the importance of experiential similarity deserve further investigation. However, this review highlights a lack of demonstrated efficacy of volunteer mentoring for carers of people with dementia.

    Healthy individuals may be exposed and sensitised to allergens, and have a positive response to a skin prick test despite being asymptomatic. The objectives of this study were to evaluate the prevalence of atopic sensitisation and identify the reactivity of healthy volunteers to common aeroallergens. Healthy volunteers with no known allergic symptoms were recruited in this study. All volunteers were scheduled to undergo a skin prick test with 16 common aeroallergens that were previously identified among atopic patients. A total of 100 volunteers (mean age 28 years) were enrolled in this study. 42 volunteers had positive skin prick tests for at least one allergen. The median number of sensitised allergen was 2 (range 1-7). Volunteers with positive skin tests (n = 42) were younger than those with negative skin tests (n = 58) (mean age 25.5 vs. 29.2 years; p mite (n = 33), house dust (n = 23) and American cockroach (n = 20). In this study, up to 42% of healthy volunteers, particularly those with a family history of atopy, were sensitised to allergens. Reactivity of the skin test without allergic symptoms, however, does not indicate allergic disease. Therefore, the skin test should only be indicated in atopic symptomatic individuals.

    Full Text Available The measurement of emotional intelligence abilities is one of the new subjects and important in human behavior studies. According to this matter, purpose of this research is consideration of emotional intelligence abilities in public sport events volunteers in 2011. For this purpose, Bradbury and Cruise's standard questionnaire was completed by present volunteers in event (n=80. The results indicated that 4 levels of emotional intelligence in volunteers are higher than expectational average significantly (p<0.01. Also, priority of emotional intelligence abilities indicated that self-awareness is first priority and social awareness, relationship management and self-management are second, third and fourth priorities in volunteers. Finally, in the basis of parameter, results stated that there is no difference between male and female volunteers emotional intelligence in first Olympia of public sport. According to results of present research and advantages of attention to emotional intelligence and human behavior in organizations, it recommended sport events managers to be more sensitive relative to human behavior abilities in human behavior abilities in human resource (volunteers under his management. At least, result of this meditation in student's sport is recruitment and development of motivated volunteers for continuous attendance in sport events.

    Five healthy volunteers were injected intravenously with 73-90 uCi purified human 131I-Antithrombin III (AT III), specific biological activity 5.6 U/mg. The tracer data were analysed using a three compartment model. The plasma radioactivity half life was 66.2 +/- 1.2 (sem) h, the fractional catabolic rate constant of the plasma pool was 0.025 +/- 0.002 (sem) h-1. These data were comparable with those described in the literature. Because of the difficulty in translating the mathematical analysis of various compartments into the biological model, biodistribution was monitored by a gamma camera linked to a DEC PDP 11/34 computer system. Dynamic and static images were obtained at fixed time intervals following the injection of 131I-AT III. Whole body scanning at intervals between the time of injection (t = 0) and t = 24.5 h showed 131I-AT III distribution over the heart, lungs, liver, spleen and great vessels. Dynamic scanning was performed over the heart, spleen and liver. Overlayed frames in the first ten minutes after the 131I-AT III injection showed the following radioactivity expressed as percentage of the injected dose; 5.9% +/- 0.3 (sem) over the heart, 10.6% +/- 0.9 (sem) over the liver and 1.1% +/- 0.1 (sem) over the spleen. A slower decline of the radioactivity between t = 0 and t = 24 h; (19%) was measured over the liver compared with the radioactivity disappearance over the heart region. This shows, in combination with the fact that the radioactivity disappearance over the heart was identical with the radioactivity decline measured in the plasma samples that retention of 131I-AT III occurred in the liver.(ABSTRACT TRUNCATED AT 250 WORDS)

    Puerto Ricans are a unique Hispanic population with European, Native American (Taino), and higher West African ancestral contributions than other non-Caribbean Hispanics. In admixed populations, such as Puerto Ricans, genetic variants can be found at different frequencies when compared to parental populations and uniquely combined and distributed. Therefore, in this review, we aimed to collect data from studies conducted in healthy Puerto Ricans and to report the frequencies of genetic polymorphisms with major relevance in drug response. Filtering for healthy volunteers or individuals, we performed a search of pharmacogenetic studies in academic literature databases without limiting the period of the results. The search was limited to Puerto Ricans living in the island, excluding those studies performed in mainland (United States). We found that the genetic markers impacting pharmacological therapy in the areas of cardiovascular, oncology, and neurology are the most frequently investigated. Coincidently, the top causes of mortality in the island are cardiovascular diseases, cancer, diabetes, Alzheimer's disease, and stroke. In addition, polymorphisms in genes that encode for members of the CYP450 family (CYP2C9, CYP2C19, and CYP2D6) are also available due to their relevance in the metabolism of drugs. The complex genetic background of Puerto Ricans is responsible for the divergence in the reported allele frequencies when compared to parental populations (Africans, East Asians, and Europeans). The importance of reporting the findings of pharmacogenetic studies conducted in Puerto Ricans is to identify genetic variants with potential utility among this genetically complex population and eventually move forward the adoption of personalized medicine in the island.

  17. Probabilistic Flood Mapping using Volunteered Geographical Information

    2016-12-01

    Flood extent maps are widely used by decision makers and first responders to provide critical information that prevents economic impacts and the loss of human lives. These maps are usually obtained from sensory data and/or hydrologic models, which often have limited coverage in space and time. Recent developments in social media and communication technology have created a wealth of near-real-time, user-generated content during flood events in many urban areas, such as flooded locations, pictures of flooding extent and height, etc. These data could improve decision-making and response operations as events unfold. However, the integration of these data sources has been limited due to the need for methods that can extract and translate the data into useful information for decision-making. This study presents an approach that uses volunteer geographic information (VGI) and non-traditional data sources (i.e., Twitter, Flicker, YouTube, and 911 and 311 calls) to generate/update the flood extent maps in areas where no models and/or gauge data are operational. The approach combines Web-crawling and computer vision techniques to gather information about the location, extent, and water height of the flood from unstructured textual data, images, and videos. These estimates are then used to provide an updated flood extent map for areas surrounding the geo-coordinate of the VGI through the application of a Hydro Growing Region Algorithm (HGRA). HGRA combines hydrologic and image segmentation concepts to estimate a probabilistic flooding extent along the corresponding creeks. Results obtained for a case study in Austin, TX (i.e., 2015 Memorial Day flood) were comparable to those obtained by a calibrated hydrologic model and had good spatial correlation with flooding extents estimated by the Federal Emergency Management Agency (FEMA).

    In recent years volunteers have become part of the maternity services to support midwives in the UK. Future midwifery students are being expected to have gained such experience when applying for courses. They are providing significant support for women in relation to breastfeeding and in other supportive roles. However this article aims to explore what volunteers are doing, questions whether the recent shortage of midwives is leading to volunteers being asked to take on tasks that are beyond their unpaid status and asks who is really benefiting from this role.

    Full Text Available A new methodology for the generation of flood hazard maps is presented fusing remote sensing and volunteered geographical data. Water pixels are identified utilizing a machine learning classification of two Landsat remote sensing scenes, acquired before and during the flooding event as well as a digital elevation model paired with river gage data. A statistical model computes the probability of flooded areas as a function of the number of adjacent pixels classified as water. Volunteered data obtained through Google news, videos and photos are added to modify the contour regions. It is shown that even a small amount of volunteered ground data can dramatically improve results.

    The purpose of this study is to identify the factors that influence the amount of volunteer work that older Mexican Americans perform in the place where they worship. The relationship between religion and volunteering is viewed from a social identity perspective. Data from a nationally representative sample of older Mexican Americans suggest that Evangelical/Pentecostal church members spend more time performing volunteer work at church than older Mexican Americans who affiliate with other denominations. Moreover, the findings indicate that the difference in the amount of volunteering between the two groups can largely be explained by differences in the nature of the spiritual support that Evangelical/Pentecostal receive from their fellow church members as well as depth of their commitment to their faith.

    This case study examines the current state of cultural competence in hospice and palliative care in the Greater Toronto Area (GTA). Because of changing demographic trends and ethnic minorities underutilizing hospice palliative care services, this research examined the current state of culturally competent care in a hospice setting, and the challenges to providing culturally competent care in a hospice in the GTA. A case study was conducted with a hospice and included in-depth interviews with 14 hospice volunteers. The findings reveal that volunteers encountered cultural clashes when their level of cultural competency was weak. Second, volunteers revealed there was a lack of adequate cultural competency training with their hospice, and finally, there was a lack of ethnic, cultural, and linguistic diversity among the hospice volunteers.

    2014-10-01

    The current study examined the relationship between conscientiousness, work status, and volunteering utilizing two large samples, the St. Louis Personality and Aging Network (SPAN) and the Health and Retirement Study (HRS). It was hypothesized that conscientious adults who were retired would be more likely to volunteer because, after retirement, they gain a substantial amount of free time, while losing an outlet for their industrious and achievement-striving tendencies. Cross-sectional and longitudinal analyses revealed that conscientious, retired individuals were more likely to volunteer than conscientious, working individuals. Further analyses revealed that facets of conscientiousness provide differential information from the general trait. These findings indicate that volunteering during retirement fills an important niche for high-striving, conscientious individuals.

    2016-12-01

    To review factors shaping volunteering in palliative care in Australian rural communities using Australian and International literature. Identify gaps in the palliative care literature and make recommendations for future research. A comprehensive literature search was conducted using Proquest, Scopus, Sage Premier, Wiley online, Ovid, Cochran, Google Scholar, CINAHL and Informit Health Collection. The literature was synthesised and presented in an integrated thematic narrative. Australian Rural communities. While Australia, Canada, the United States (US) and the United Kingdom (UK) are leaders in palliative care volunteer research, limited research specifically focuses on volunteers in rural communities with the least occurring in Australia. Several interrelated factors influence rural palliative care provision, in particular an increasingly ageing population which includes an ageing volunteer and health professional workforce. Also current and models of palliative care practice fail to recognise the innumerable variables between and within rural communities such as distance, isolation, lack of privacy, limited health care services and infrastructure, and workforce shortages. These issues impact palliative care provision and are significant for health professionals, volunteers, patients and caregivers. The three key themes of this integrated review include: (i) Geography, ageing rural populations in palliative care practice, (ii) Psychosocial impact of end-end-of life care in rural communities and (iii) Palliative care models of practice and volunteering in rural communities. The invisibility of volunteers in rural palliative care research is a concern in understanding the issues affecting the sustainability of quality palliative care provision in rural communities. Recommendations for future Australian research includes examination of the suitability of current models of palliative care practice in addressing the needs of rural communities; the recruitment

  6. Eastern Visayas: profile of the region's volunteer outreach worker.

    Science.gov (United States)

    Diaz, C A

    1983-01-01

    Volunteer outreach workers in Eastern Visayas (Region 8) who tend to remain in the Philippine Population Program are able to plan for the welfare of the family, are seriously concerned about the welfare of the community, are traditional in their beliefs about family decision making, are moderately innovative, and are relatively dissatisfied with community life. The research report submitted to the regional office of the Commission on Population (Popcom) by the Regional Research Center for Population, Leyte State College, indicated that Popcom recognizes the importance of community based fieldworkers in the delivery of its services. The study was conducted in line with efforts to improve the system of recruiting volunteer workers and to develop a more effective service delivery scheme. The researchers randomly selected a representative sample of volunteer workers--265 active and 86 inactive--from the provinces of Leyte, Southern Leyte, Eastern Samar, Western Samar and Northern Samar, the subprovince of Biliran, and the cities of Tacloban, Ormoc, and Calbayog. The active volunteer worker of Eastern Visayas is female, between 36-40 years old, married, and the mother of 3-5 children. She also considers the size of her family to be "just right." The volunteer worker believes the father is the prinicipal decision maker in the family and that parents should always be consulted on matters concerning their children. The inactive volunteer worker is also female, in the same age bracket, married, and with 3-5 children, and she also does not want to have additional children. She is more innovative and more receptive to change than the active volunteer worker. She is more satisfied with community life, is modern in her beliefs as to who is the authority in the family, and believes that children also should have a part in making family decisions. Mobility in terms of residence is an important factor in the decision of the volunteer worker to remain in or drop out of the program.

  7. Hospital administrative characteristics and volunteer resource management practices.

    Science.gov (United States)

    Intindola, Melissa; Rogers, Sean; Flinchbaugh, Carol; Della Pietra, Doug

    2016-05-16

    Purpose - The purpose of this paper is to explore the links between various characteristics of hospital administration and the utilization of classes of volunteer resource management (VRM) practices. Design/methodology/approach - This paper uses original data collected via surveys of volunteer directors in 122 hospitals in five Northeastern and Southern US states. Findings - Structural equation modeling results suggest that number of paid volunteer management staff, scope of responsibility of the primary volunteer administrator, and hospital size are positively associated with increased usage of certain VRM practices. Research limitations/implications - First, the authors begin the exploration of VRM antecedents, and encourage others to continue this line of inquiry; and second, the authors assess dimensionality of practices, allowing future researchers to consider whether specific dimensions have a differential impact on key individual and organizational outcomes. Practical implications - Based on the findings of a relationship between administrative characteristics and the on-the-ground execution of VRM practice, a baseline audit comparing current practices to those VRM practices presented here might be useful in determining what next steps may be taken to focus investments in VRM that can ultimately drive practice utilization. Originality/value - The exploration of the dimensionality of volunteer management adds a novel perspective to both the academic study, and practice, of volunteer management. To the authors' knowledge, this is the first empirical categorization of VRM practices.

    Full Text Available Studies three concepts of transformational, transactional and laissez-faire leaderships as three independent and individual dimensions. This field study is descriptive and correlative. Statistical population of this study is the volunteer students in universities' sport associations of 10 regions of the country. Among 73 universities, 17 had active sport associations. Based on Morgan table, 231 students were selected as statistical sample (n=231 from which the results of 208 questionnaires were analyzed. Bass and Avolio (1995 Multifactor Leadership Questionnaire (MLQ was used to measure managers' leadership style of the universities' sport administrations. This questionnaire includes 41 questions with 5-value Lickert scale (1=never to 5=always. Choosing satisfaction from experiencing as the most important dimension of satisfaction shows volunteers' high level of satisfaction from experiences they have acquired in universities sport associations. The reason of this fact is that sport activity in the association is long term in nature. Sport association provides the students an opportunity to experience and use their experiences in their sport and work life. This study illustrates that girls are more satisfied than boys in all satisfaction dimensions (especially acquiring experience, career, commitment, and material in sport associations. Researches show that female students' satisfaction is more than male students' satisfaction and women's job satisfaction is more than men's job satisfaction. Thus, the higher degree of job satisfaction and experiencing in female students seems more justifying. Also, it's been cleared that sport students were more satisfied than other students in all satisfaction dimensions (especially acquiring experience, career, purposeful, and commitment

    The 2001 HIV sero-prevalence survey in Nigeria revealed a rate of 5.8 percent with those under the age of 25 years having the highest prevalence rate. Most University students fall within this age group. This study is part of a larger study on the sexual behavior of youths and young adults and was designed to compare the characteristics of volunteers and non-volunteers for voluntary confidential counseling and HIV testing (VCT) among males. Six hundred and nine male undergraduate students were randomly selected and enrolled for the study. Data were collected using a pre-tested questionnaire. Of the 609, 51 (8.3%) volunteered to have their blood screened for HIV. All volunteers who received pre-test counseling went for the HIV test. Volunteers were significantly older than the non-volunteers (Pmothers who had completed secondary education (P<0.00001, (P=0.02). Among the 51 volunteers, 8 (15.7%) tested positive. Those who tested positive were less likely to have lived with parents, and were all sexually experienced. Those who screened positive were also more likely to be currently sexually active and to have fathers with low level of education. Three (5.9%) of volunteers did not return for results and posttest counseling. One of the three was positive for HIV. Of those who tested positive, 3 (37.5%) reported not using the condom at all, while the rest were using it only occasionally. VCT among the youths is possible however, small numbers encountered in the study is a limitation and there is a need to replicate this study using larger numbers. Tertiary institutions should provide VCT services for the students where they can be counseled appropriately and continuously throughout their stay in the institution. This hopefully will reduce the number of new HIV cases seen.

    Advance care planning (ACP) increases the likelihood patients will receive end-of-life care that is congruent with their preferences and lowers stress among both patients and caregivers. Previous efforts to increase ACP have mainly focused on information provision in the very late stage of life. This study examines whether a relationship exists between volunteering and ACP, and whether this relationship is associated with social support. The sample comprises 877 individuals who were aged 55+ in 2008, and were deceased before 2010. The sample is derived from seven waves (1998-2010) of data from the Health and Retirement Study. Logistic regression results showed that overall ACP and durable power of attorney for health care (DPAHC) were both higher (OR = 1.61 and 1.71, respectively) for older adults with volunteering experience in the past 10 years than those without such experience. Available social support (relatives and friends living nearby) was not associated with the relationship between volunteering and ACP. Other factors related to ACP included poorer health, death being expected, death due to cancer, older age, and being a racial minority. Involving older people in volunteer work may help to increase ACP. Future research is encouraged to identify reasons for the association between volunteering and ACP.

    This article describes, from the perspective of Project HOPE volunteers, the precedent-setting, military-civilian partnership in staffing the USNS Mercy as part of the rapid response of the United States to the overwhelming devastation and loss of life resulting from the tsunami off the coast of Indonesia. The article discusses the designation of Project HOPE as the non-governmental organization to be the single source of volunteers for the USNS Mercy mission (providing approximately 100 volunteers for each of two 30-day rotations), some issues facing Project HOPE and the contingent of volunteers in recruiting, orienting, training, and preparing for the mission, steps taken to make this a successful mission despite the ambiguity and uncertainties involved in arriving in the relief area 1 month after the disaster, and some recommendations for similar future missions. The Project HOPE volunteers quickly integrated with the cadre of Navy health professionals to deliver a broad range of high-quality care, including tertiary care, attesting to the professionalism and standards common to military and civilian medicine. The combined success of all organizations involved truly heralds a new era of medical diplomacy and goodwill in which the United States can take great pride.

  16. The Impact of Acculturation on Informal and Formal Volunteering of Korean Americans in the United States

    Directory of Open Access Journals (Sweden)

    Hee Soun Jang

    2016-04-01

    Full Text Available This study examines the impact of acculturation on Korean Americans’ decisions to volunteer either for secular and religious organizations or informally. The results show that language difficulty and Korean identity lower the likelihood of secular volunteering, but not of informal volunteering. Koreans who are Protestants or Catholics, and those with higher levels of education, are more likely to volunteer formally, but not informally. The findings indicate formal volunteering is strongly associated with acculturation factors, along with personal and social variables but informal volunteering appears to be independent from and not complementary of the other two types of volunteering.

    Full Text Available This study explores the relationship between coping styles and strategies, and personality styles in a sample of 41 young volunteers of an institution that alleviates poverty in Lima. Peruvian adaptations of COPE and MIPS scales were administered. The results show that volunteers have higher scores on adaptive coping strategies. High scores in some particular personality styles were reported, which allowed to establish a personality profile of this group. According with theoretical framework, most coping strategies correlated with most personality styles, revealing four particular tendencies in these volunteers: they wish to have contact with other people, they usually see positive aspects of situations, they look forward for challenges, and they developed adaptive coping strategies.

    A recent common theme among HEP computing is exploitation of opportunistic resources in order to provide the maximum statistics possible for Monte Carlo simulation. Volunteer computing has been used over the last few years in many other scientific fields and by CERN itself to run simulations of the LHC beams. The ATLAS@Home project was started to allow volunteers to run simulations of collisions in the ATLAS detector. So far many thousands of members of the public have signed up to contribute their spare CPU cycles for ATLAS, and there is potential for volunteer computing to provide a significant fraction of ATLAS computing resources. Here we describe the design of the project, the lessons learned so far and the future plans.

    2005-01-01

    Volunteerism assumes a growing importance in the context of health, due to the significant number of practitioners and to the contribution given by the volunteers in the humanization of health care. However, as the continued interaction with the sick person might also originate negative emotions, we looked up in this article to describe the main results about vulnerability to stress in volunteers. The results revealed that 30.00% of volunteers were vulnerable to stress. We also observed that the civil state, socio-economic level and familiar functionality variables revealed to be protectors of the occurrence of stress. On the other side, the predominance of neuroticism as a personality trace was associated to a higher vulnerability to stress.

  4. Pharmacokinetic studies of antipsychotics in healthy volunteers versus patients.

    Cutler, N R

    2001-01-01

    In clinical trials of dopamine-blocking antipsychotics, significant adverse events may occur in healthy volunteers at dose levels that are well tolerated by schizophrenic patients. Because of these differences in tolerability, bioequivalence and pharmacokinetic studies of antipsychotics should be performed in schizophrenic patients rather than in healthy volunteers. When clozapine is the drug being investigated, pharmacokinetic and bioequivalence studies should be carried out in real-life dosage conditions because the half-life of clozapine increases with multiple doses. Under real-life conditions, the evaluation of multiple doses of clozapine in a population of schizophrenic patients can provide direct therapeutic relevance to bioavailability findings. This article discusses patient recruitment and informed consent in pharmacokinetic trials of schizophrenia, issues in studying antipsychotic agents in healthy volunteers versus schizophrenic patients, and a bioequivalency study of Clozaril (Novartis Pharmaceuticals) and generic clozapine (Creighton [Sandoz]) in schizophrenic patients.

    The frequency of formal volunteering varies widely across European countries, and rates of formal volunteering are especially low among Eastern European countries. Why are there such large differences in volunteering rates when it is known that volunteering is beneficial for well-being? Using data from the latest round of the European Social Survey, we test three hypotheses to explain these cross-national differences in volunteering. We ask whether people in countries with low frequencies of ...

    Environmental volunteering (EV) can provide a unique way to optimise the wellbeing of participants while fostering environmental stewardship. However, the potential of EV to create human health benefits remains an under-researched area. This study provides evidence for improved wellbeing and mood state for 32 participants from diverse backgrounds undertaking EV activities. Most participants also reported improved environmental stewardship with a greatly improved understanding of the environment and the need to conserve it. Other benefits included: 31% of those seeking work obtained it; and 50% joined a volunteer group at program completion. EV provides a unique mechanism to enhance the wellbeing of the participants, while conserving the environment.

    Not only the health service but also several other humanitarian institutions and societies were active in Abbazia÷Opatija, the most important town on the once Austrian Riviera, the town that was also known as the Austrian Nice. The most important of the societies was The Health Resort Opatija Volunteer Fire Brigade and Rescue Society. The authors of this article have been particularly interested in the society's founding and its activity until it moved into the new building at 6, St. Florjan's Street in 1910. The fast urbanisation and the development of the industry raised the need of the well organised activity of putting out fires. The German gymnastics societies were the first to include the education and the skills development of the volunteer firemen into their programmes. The first volunteer fire brigades appeared in Austria after 1863. The huge fire that broke out in Vienna in 1881 showed that the fast and efficient rescuing demanded a well prepared organization of a team of rescuers. Based on the initiative of the chimney sweep Franz Drescher and The South Railway Company, the volunteer fire brigade was founded in Opatija already in 1886. The founding of the volunteer rescue society was based on the idea given by dr. Jaromir Mundy, the permanent guest in Opatija and a friend of prof. dr. Theodor Billroth, in 1894. The intertwining activity of the both societies resulted in their formal joining. The head physician became dr. Franz Tripold, the chief commander was Franz Doberlet junior. For his special merits, the general assembly of the Health Resort Opatija Volunteer Fire Brigade and Rescue Society appointed him the honourable commander of the society in 1903 and he received a special photo album with the photos of the volunteer firemen and the rescuers' practice. The Emperor Franz Joseph I Jubilee Fire Station, the Rescue Station And the Sanatorium (Kaiser Franz Joseph I Jubiläums - Feuerwehrrüstungshaus, Rettungsstation und Erholungsheim) was given to

    Pathologists Overseas is a nonprofit organization that has been coordinating the efforts of volunteer pathologists and technologists for 19 years to improve and provide affordable pathology services to underserved patients worldwide. This is accomplished by aiding and establishing pathology laboratories, providing diagnostic pathology services, and training local physicians as pathologists. Projects have been completed or are currently active in Kenya, Eritrea, Madagascar, Ghana, Nepal, Bhutan, Peru, El Salvador, and St Lucia. The main challenge is finding enough volunteers to provide uninterrupted service to maintain a project. Our goal is to build on these experiences and continue to both support existing and establish more pathology laboratories worldwide.

    The Galaxy Zoo citizen science website invites anyone with an Internet connection to participate in research by classifying galaxies from the Sloan Digital Sky Survey. As of April 2009, more than 200,000 volunteers had made more than 100 million galaxy classifications. In this paper, we present results of a pilot study into the motivations and demographics of Galaxy Zoo volunteers, and define a technique to determine motivations from free responses that can be used in larger multiple-choice surveys with similar populations. Our categories form the basis for a future survey, with the goal of determining the prevalence of each motivation.

    There is a great need for practicing scientists to volunteer their time and expertise in the K-12th grade science classroom. We have found that bioluminescence is a fun and exciting way to teach basic science concepts and is an excellent tool for the volunteering scientist. We have had very positive reactions from both teachers and students. The excitement of the students when they first see bioluminescence is contagious. Bioluminescent dinoflagellates are one of the easiest ways to introduce students to this fascinating topic. Many activities and experiments can be done using the bioluminescent dinoflagellates and many students and teachers could benefit from your knowledge and expertise. See you in the classroom.

    2016-11-01

    Full Text Available Background: Environmental volunteering can increase well-being, but environmental volunteer well-being has rarely been compared to participant well-being associated with other types of volunteering or nature-based activities. This paper aims to use a multidimensional approach to well-being to explore the immediately experienced and later remembered well-being of environmental volunteers and to compare this to the increased well-being of participants in other types of nature-based activities and volunteering. Furthermore, it aims to compare volunteer managers’ perceptions of their volunteers’ well-being with the self-reported well-being of the volunteers. Methods: Onsite surveys were conducted of practical conservation and biodiversity monitoring volunteers, as well as their control groups (walkers and fieldwork students, respectively, to measure general well-being before their nature-based activity and activity-related well-being immediately after their activity. Online surveys of current, former and potential volunteers and volunteer managers measured remembered volunteering-related well-being and managers’ perceptions of their volunteers’ well-being. Data were analysed based on Seligman’s multidimensional PERMA (‘positive emotion’, ‘engagement’, ‘positive relationship’, ‘meaning’, ‘achievement’ model of well-being. Factor analysis recovered three of the five PERMA elements, ‘engagement’, ‘relationship’ and ‘meaning’, as well as ‘negative emotion’ and ‘health’ as factors. Results: Environmental volunteering significantly improved positive elements and significantly decreased negative elements of participants’ immediate well-being, and it did so more than walking or student fieldwork. Even remembering their volunteering up to six months later, volunteers rated their volunteering-related well-being higher than volunteers rated their well-being generally in life. However, volunteering was not

    2015-01-01

    Although Cryptosporidium parvum and C. hominis cause the majority of human cryptosporidiosis cases, other Cryptosporidium species are also capable of infecting humans, particularly when individuals are immunocompromised. Ten C. muris cases have been reported, primarily in human immunodeficiency virus (HIV) -positive patients with diarrhea. However, asymptomatic cases were reported in two HIV-negative children, and in another case, age and immune status were not described. This study examines the infectivity of C. muris in six healthy adults. Volunteers were challenged with 105 C. muris oocysts and monitored for 6 weeks for infection and/or illness. All six patients became infected. Two patients experienced a self-limited diarrheal illness. Total oocysts shed during the study ranged from 6.7 × 106 to 4.1 × 108, and the number was slightly higher in volunteers with diarrhea (2.8 × 108) than asymptomatic shedders (4.4 × 107). C. muris-infected subjects shed oocysts longer than occurred with other species studied in healthy volunteers. Three volunteers shed oocysts for 7 months. Physical examinations were normal, with no reported recurrence of diarrhea or other gastrointestinal complaints. Two persistent shedders were treated with nitazoxanide, and the infection was resolved. Thus, healthy adults are susceptible to C. muris, which can cause mild diarrhea and result in persistent, asymptomatic infection. PMID:25311695

  11. "Why am i a volunteer?": building a quantitative scale

    Directory of Open Access Journals (Sweden)

    Carlos Eduardo Cavalcante

    Full Text Available This paper aims to analyze the validity of a quantitative instrument to identify what attracts someone to volunteer work, as well as what makes them stay and what makes them quit such an activity. The theoretical framework lists aspects related to volunteer work, which is followed by a discussion on models of analysis of volunteer motivation. As to the objectives, this research is descriptive, since it presents the analysis of the validity of a quantitative instrument that seeks to understand and describe the reasons for volunteering at the Pastoral da Criança, a Brazilian NGO. This instrument is based on theoretical ideas by Souza, Medeiros and Fernandes (2006. Reliability - Cronbach's Alpha - reached values between 0.7 and 0.8. Regarding Kaiser-Meyer-Olkin measure of sampling adequacy a good index was also obtained: 0.74. Despite the good results of reliability and sampling adequacy of factor analysis, none of the variables resulted in the expected combination, namely: indicators versus profile. It is necessary to improve the semantic meaning of certain factors, or even increase the number of indicators so as to generate additional correlations among them.

  12. Understanding volunteer peer health educators' motivations: applying social learning theory.

    Science.gov (United States)

    Klein, N A; Sondag, K A; Drolet, J C

    1994-11-01

    We conducted focus group interviews with students who were current peer health educators at a mid-sized university to determine what factors motivate individuals to volunteer for a peer health education program. Specifically, we asked the participants questions designed to explore their life experiences, their expectations of the peer education program, and their motivations. Constructs from social learning theory were used to categorize and contribute to our understanding of the responses. Many participants specified experiences with family members or friends, such as alcoholism or other illnesses, that had influenced their decisions. Participants' expectation of the program varied greatly and did not indicate a strong link to the decision to volunteer. The peer health educators' motivations for volunteering were altruistic, such as wanting to help others; egotistic, such as wanting job training; or related to self-efficacy beliefs, such as satisfying a personal need for health education. This study indicated that life experiences, a belief in the effectiveness of peer health education programs, and positive reinforcement to join influence the decision to volunteer. Implications for coordinating peer education programs are discussed.

    In Taiwan's current counseling centers for the elderly, large numbers of volunteers are supervised by only a few social workers or nurses, so the roles and functions of these volunteers are very important. A neat summary of the services provided by the volunteers would include: (1) Direct services: telephone counseling, telephone interviewing, case handling, mail counseling, resource provision. (2) Indirect services: fundraising, supervision. (3) Administration: administrative assistance, management of institutional web sites. (4) Strategic consultancy: consultancy, provision of expertise. (5) Advocacy: service as educators and spokespersons; public relations and marketing. (6) MANAGEMENT: team leadership, plan implementation. To sum up, their functions are, by means of telephone and face-to-face contact, to provide information to the elderly about finances, medical services, housing, citizenship, the dignity of life and death, and related issues, as well as to serve as advocates for the provision of resources--such as educational courses--and to facilitate such provision. Indeed, the roles and functions of volunteer counselors become more diverse and more comprehensive by the day.

    2006-07-01

    As charismatic mega-fauna, sea turtles attract many volunteers to conservation programs. This article examines the ways in which volunteers value sea turtles, in the specific context of volunteers working with the Caribbean Conservation Corporation, at Tortuguero, Costa Rica. The complexity of volunteer values is explored using a qualitative approach. In-depth interviews with 31 volunteers were conducted in July of 1999 and 2000. Interviews probed, among other things, interest in sea turtles and their conservation, motives for participating, and the most gratifying parts of their volunteer experience. Results show that volunteers hold multiple and complex values for sea turtles, but particular values dominate. Results have implications for understanding human-environment relations and the emerging study of volunteer tourism. There are also management implications for volunteer programs hoping to attract participants.

    2003-06-01

    Following a meta-analysis of the relations between age and volunteer motives (career, understanding, enhancement, protective, making friends, social, and values), the authors tested hypotheses derived from socioemotional selectivity theory regarding the effects of age on these volunteer motives. The Volunteer Functions Inventory was completed by 523 volunteers from 2 affiliates of the International Habitat for Humanity. Multiple regression analyses revealed, as predicted, that as age increases, career and understanding volunteer motivation decrease and social volunteer motivation increases. Contrary to expectations, age did not contribute to the prediction of enhancement, protective, and values volunteer motivations and the relation between age and making friends volunteer motivation was nonlinear. The results were discussed in the context of age-differential and age-similarity perspectives on volunteer motivation.

    Thromboelastography (TEG) provides a functional evaluation of coagulation. It has characteristics of an ideal coagulation test for trauma, but is not frequently used, partially due to lack of both standardized techniques and normal values. We determined normal values for our population, compared them to those of the manufacturer and evaluated the effect of gender, age, blood type, and ethnicity. The technique was standardized using citrated blood, kaolin and was performed on a Haemoscope 5000 device. Volunteers were interviewed and excluded if pregnant, on anticoagulants or having a bleeding disorder. The TEG parameters analyzed were R, K, alpha, MA, LY30, and coagulation index. All volunteers outside the manufacturer's normal range underwent extensive coagulation investigations. Reference ranges for 95% for 118 healthy volunteers were R: 3.8-9.8 min, K: 0.7-3.4 min, alpha: 47.8-77.7 degrees, MA: 49.7-72.7 mm, LY30: -2.3-5.77%, coagulation index: -5.1-3.6. Most values were significantly different from those of the manufacturer, which would have diagnosed coagulopathy in 10 volunteers, for whom additional investigation revealed no disease (81% specificity). Healthy women were significantly more hypercoagulable than men. Aging was not associated with hypercoagulability and East Asian ethnicity was not with hypocoagulability. In our population, the manufacturer's normal values for citrated blood-kaolin had a specificity of 81% and would incorrectly identify 8.5% of the healthy volunteers as coagulopathic. This study supports the manufacturer's recommendation that each institution should determine its own normal values before adopting TEG, a procedure which may be impractical. Consideration should be given to a multi-institutional study to establish wide standard values for TEG.

    AIM:Evaluation of the wide range of normal findings in asymptomatic women undergoing dynamic magnetic resonance (MR) defecography.METHODS:MR defecography of 10 healthy female volunteers (median age:31 years) without previous pregnancies or history of surgery were evaluated.The rectum was filled with 180 mL gadolinium ultrasound gel mixture.MR defecography was performed in the supine position.The pelvic floor was visualized with a dynamic T2-weighted sagittal plane where all relevant pelvic floor organs were acquired during defecation.The volunteers were instructed to relax and then to perform straining maneuvers to empty the rectum.The pubococcygeal line (PCGL) was used as the line of reference.The movement of pelvic floor organs was measured as the vertical distance to this reference line.Data were recorded in the resting position as well as during the defecation process with maximal straining.Examinations were performed and evaluated by two experienced abdominal radiologists without knowledge of patient history.RESULTS:Average position of the anorectal junction was located at-5.3 mm at rest and-29.9 mm during straining.The anorectal angle widened significantly from 93° at rest to 109° during defecation.A rectocele was diagnosed in eight out of 10 volunteers showing an average diameter of 25.9 mm.The bladder base was located at a position of +23 mm at rest and descended to-8.1 mm during defecation in relation to the PCGL.The bladder base moved below the PCGL in six out of 10 volunteers,which was formally defined as a cystocele.The uterocervical junction was located at an average level of +43.1 mm at rest and at +7.9 mm during straining.The uterocervical junction of three volunteers fell below the PCGL; described formally as uterocervical prolapse.CONCLUSION:Based on the range of standard values in asymptomatic volunteers,MR defecography values for pathological changes have to be re-evaluated.

    Ambiguous feelings regarding women engaging in formal volunteering and concerns about their exploitation might explain the dearth of studies regarding the volunteering benefits specifically experienced by low socioeconomic status women. The current study examined benefits of volunteering among women participating in Women for Women's Health (WWH), a lay health volunteers (LHV) programme implemented in Jewish and Arab communities in Israel, and aiming at empowering such women to become active volunteers and promote health activities in their communities. Two years after the introduction of WWH in each community, all 45 Jewish and 25 Arab volunteers were contacted by phone and invited to participate in the focus group discussions. Five focus group discussions were conducted with 25/42 Jewish volunteers in 2003 and four with 20/25 Arab volunteers in 2005. The other volunteers could not attend the scheduled meetings or became inactive for personal reasons. Four benefit categories were identified in both ethnic groups: 1. Personal benefits of having increased knowledge, feeling self-satisfaction, mastering new skills and performing healthy behaviours; 2. Group-social benefits of social support and sense of cohesion; 3. Purposive benefits of achieving the WWH mission and goals; 4. Sociopolitical benefits of learning to accept the other and experiencing increased solidarity. However, the relatively less privileged Arab volunteers enumerated more benefits within the personal and purposive categories. They also identified the unique sociocultural category of improving women's status in the community by creating a legitimate space for women by public sphere involvement, traditionally solely a male domain. We conclude that volunteering in community-based health promotion programmes can be an empowering experience for lay women without being exploitative. Positive volunteering benefits will be even more discernable among underprivileged women who enjoy fewer opportunities in

    The present study was undertaken to determine those variables which best predict college students' reactions to lectures designed to solicit volunteers for a juvenile corrections program. One hundred and thirty-four students returned mailed questionnaires which assessed multiple variables related to: (1) audience characteristics, (2) recruiter (lecturer) characteristics, and (3) volunteer program (lecture content) characteristics. Results of canonical correlation analysis indicated that 8 of 17 predictor variables accounted for the majority of the variance in the volunteering behavior variate. Age of respondent, previous volunteer experience, overall lecture quality, understanding need for volunteer services, clarity and comprehension of volunteer roles, the value of the lecture as a significant learning experience, the opportunity for personal growth within the program, and the ability to influence existing structures were seen as important variables in predicting three volunteering behaviors. In particular, the data suggest that for recruitment programs using the lecture method recruiter characteristics have the greatest impact on soliciting volunteer personnel.

    The massive destruction caused by Hurricanes Katrina and Rita in 2005 provided an opportunity for many volunteers to be involved with disaster relief work. Exposure to devastation and personal trauma can have long-lasting and sometimes detrimental effects on people providing help. This qualitative study explored the experience of volunteer relief workers who provided disaster relief services after the hurricanes. Three major themes emerged: emotional reactions that included feelings of shock, fatigue, anger and grief as well as sleep disturbances; frustration with leadership; and life-changing personal transformation. Stress reactions were noted but appeared to be mitigated by feelings of compassion for the victims and personal satisfaction in being able to provide assistance. Suggestions are provided for further research.

    Objective To observe the changes of plasma glucose level (PGL) in human volunteers after acupuncture. Methods Seventy-seven human volunteers were taken up from the acupuncture clinic. All of pletion of acupuncture. All cases were at four hours abstinence from food before doing acupuncture. Results Plasma glucose level varied 5 mg% or more in 62 cases (80.51%) and only those were considered for computation. PGL increased in cases who had generally plasma glucose level below 90 mg% before acupuncture;and PGL decreased in cases who had plasma glucose 90 mg% or above. In 10 control cases there was no variation of the considerable level of 5 mg% in any case. Conclusion Bi-directional variation of PGL after acupuncture indicates that acupuncture can be used to maintain optimum PGL through endogenous mechanism,suggesting that it is applicable in controlling hyperglycemia in diabetes mellitus patients.

    We examined the process of accruing healthy control subjects for biomedical research on brain function. Of 1670 responders to newspaper advertising, 23.1% were uninterested when learning more about the studies, and 50.9% of those remaining were found by structured telephone screening to meet exclusionary criteria for having a history of psychiatric, neurologic, or medical disease that might affect brain function. Of 312 volunteers passing the telephone screening who came to an in-person evaluation by a physician and agreed to participate, 49.7% were found to meet exclusionary criteria, and only 157 were admitted to the study. This underscores the importance of attending to the issue of screening and assessment of "normal volunteers." Alternative strategies should be considered for enriching the pool.

    2012-01-01

    Volunteered geographic information (VGI), one of the most important types of user-generated web content, has been emerging as a new phenomenon. VGI is contributed by numerous volunteers and supported by web 2.0 technologies. This chapter discusses how VGI provides new perspectives for computational geography, a transformed geography based on the use of data-intensive computing and simulations to uncover the underlying mechanisms behind geographic forms and processes. We provide several exemplars of computational geography using OpenStreetMap data and GPS traces to investigate the scaling of geographic space and its implications for human mobility patterns. We illustrate that the field of geography is experiencing a dramatic change and that geoinformatics and computational geography deserve to be clearly distinguished, with the former being a study of engineering and the latter being a science.

    Obesity is prevalent among career firefighters and may contribute to heart attacks, a leading cause of on-duty fatalities. The US National Fire Protection Association estimates that 800 000 of 1.1 million firefighters are volunteers. Body mass index (BMI) is commonly used to assess obesity, but little is known about its accuracy in volunteer firefighters, in whom muscle mass may be higher, given firefighting's physical demands, reducing its accuracy in identifying obesity. To evaluate the accuracy of BMI in identifying obese volunteer firefighters. Height, weight and body composition were measured in 73 male volunteer firefighters (mean age 40±12). The proportions with BMI ≥ 25kg/m(2), ≥30kg/ m(2) and percent fat ≤ 20th percentile were determined. Using the age-specific 20th percentile for percent fat (Cooper Clinic) as the criterion for being over-fat, the accuracy of BMI was assessed using sensitivity and specificity calculations. The means ± standard deviation of BMI and percent fat were 32±6 and 25±5, respectively. The proportions with a BMI ≥ 25 and ≥30 were 90% and 60%, respectively. Fifty-one percent had a percent fat ≤ 20th percentile. The measure BMI ≥ 25 had a perfect sensitivity (1.0) and low specificity (0.19) and BMI ≥ 30 had a high sensitivity (0.89) and moderate specificity (0.69). Although BMI ≥ 30 accurately predicted being over-fat, it misclassified large and lean firefighters. Although BMI should be used cautiously, it can identify over-fat firefighters at risk of cardiovascular disease, and its measurement is cost-effective and simple.

Changing living conditions and changing values can affect both the level and the nature of volunteering. Most Western societies have over the last 30 years or more experienced...... preconditions for volunteering have had an effect on factors that are commonly associated with volunteering. We use survey data from Denmark collected over a period from 1990 to 2008....

  13. Charity begins at home: How socialization experiences influence giving and volunteering

    2005-01-01

    This paper shows that charity begins at home. Using retrospective reports on youth experiences from the Giving in the Netherlands Panel Survey (n=1,964, 2001) I find that (1) parents who volunteer when their children are young promote giving and volunteering of their children once they have become adults; (2) the intensity of youth participation in nonprofit organizations is positively related to current giving and volunteering; (3) that parental volunteering and youth participation promote c...

  14. The fallacy of the Good Samaritan: Volunteering as a weird way of making money

    This paper explores individual motives for volunteering: The analysis is based on the interpretation of volunteering as a consumption good (consumption model) or as a mean to increase individual’s own human capital (investment model). We present an econometric framework taking into account self selection into volunteering and simultaneity between the volunteering decision and the determination of income in order to test these two models and to identify the underlying motives. We find strong s...

  15. Should desperate volunteers be included in randomised controlled trials?

    Allmark, P; Mason, S

    2006-09-01

    Randomised controlled trials (RCTs) sometimes recruit participants who are desperate to receive the experimental treatment. This paper defends the practice against three arguments that suggest it is unethical first, desperate volunteers are not in equipoise. Second clinicians, entering patients onto trials are disavowing their therapeutic obligation to deliver the best treatment; they are following trial protocols rather than delivering individualised care. Research is not treatment; its ethical justification is different. Consent is crucial. Third, desperate volunteers do not give proper consent: effectively, they are coerced. This paper responds by advocating a notion of equipoise based on expert knowledge and widely shared values. Where such collective, expert equipoise exists there is a prima facie case for an RCT. Next the paper argues that trial entry does not involve clinicians disavowing their therapeutic obligation; individualised care based on insufficient evidence is not in patients best interest. Finally, it argues that where equipoise exists it is acceptable to limit access to experimental agents; desperate volunteers are not coerced because their desperation does not translate into a right to receive what they desire.

    Saffron (Crocus sativus) stigma tablets were evaluated for short-term safety and tolerability in healthy adult volunteers. The study was a double-blind, placebo-controlled design consisting of a 1 week treatment of saffron tablets. Volunteers were divided into 3 groups of 10 each (5 males and 5 females). Group I received placebo; groups 2 and 3 received 200 and 400mg saffron tablets, respectively, for 7 days. General measures of health were recorded during the study such as hematological, biochemical and electrocardiographic parameters done in pre- and post-treatment periods. Clinical examination showed no gross changes in all volunteers after intervention. Saffron with higher dose (400mg) decreased standing systolic blood pressure and mean arterial pressures significantly. Saffron decreased slightly some hematological parameters such as red blood cells, hemoglobin, hematocrit and platelets. Saffron increased sodium, blood urea nitrogen and creatinine. This study showed that saffron tablets may change some hematological and biochemical parameters. However, these alterations were in normal ranges and they were not important clinically.

  17. How volunteering helps students to develop soft skills

    2017-06-01

    It is widely recognised that tertiary education does not provide all of the knowledge and skills required to succeed in modern societies. Personal and interpersonal skills - so-called "soft skills" - are also needed to complement professional skills and expertise, and become an essential part of an individual's personality. One way of acquiring soft skills is volunteering with associations and non-governmental organisations (NGOs). This paper discusses the involvement of French third-level students in voluntary activities and the skills they acquire as a result. The author presents the findings of a study involving a questionnaire and semi-structured interviews. Results show that many students develop skills linked to their future professional career, that they reflect on this consciously and feel enriched by the experience. The author argues that "non-professional" activities like volunteering can be actively incorporated into students' learning process, making their overall experience of higher education more active, enjoyable and relevant. Learning through action was found to be the most important factor in the acquisition of soft skills. This article aims to contribute to research on the educational dimension of volunteering, demonstrating that it benefits both personal and professional development.

    Full Text Available Dietary antioxidants including phenolic compounds are believed to be effective nutrients in the prevention of oxidative stress related disease. Pomegranate has been used for centuries in ancient cultures for its medicinal purpose and is widely acknowledged for antioxidant properties. The present study was designed to assess the effect of pomegranate fresh fruit consumption on the plasma antioxidant capacity. Thirty healthy volunteers were recruited for the study. Volunteers were randomly divided into three groups (pomegranate, vitamin E and water consumption. Blood samples were collected, after at least 12 hours overnight fast, the day before beginning supplementation period and the day after supplementation had finished. Total antioxidant capacity measurement by FRAP method and clinical laboratory test were performed for all volunteers in two selected times. The obtained data revealed that consumption of 100 grams pomegranate and vitamin E per day for ten days resulted in a significant rise (14.05%, 8.28% plasma antioxidant capacity respectively, but this difference was not significant for water group.

    This controlled study compared immediate effects of two relaxation techniques on state anxiety and sustained attention in healthy subjects. 86 volunteers (56 men and 30 women) were divided into two groups: the first 43 volunteers (age range 18 to 64) practiced 20 minutes of yoga-based Deep Relaxation Technique (DRT), while the second group of 43 volunteers (same age range), practiced 20 minutes Supine Rest (SR). State anxiety was assessed using the State Trait Anxiety Inventory (STAI A-State), and sustained attention was assessed using the Six Letter Cancellation (SLC) and Digit Letter Substitution (DLS) tests. All tests were administered immediately before, and immediately after, practice. A significant reduction in State Anxiety score (P < 0.001) was observed for the group practicing DRT, but not for the group practicing SR. For the sustained attention tests, however, there were significant increases in scores by both DRT and SR groups (P < 0.001). The results suggest that both interventions improve attention, but that only DRT reduces State Anxiety.

    2013-01-01

    Efforts to expand protected area networks are limited by the costs of managing protected sites. Volunteers who donate labor to help manage protected areas can help defray these costs. However, volunteers may be willing to donate more labor to some protected areas than others. Understanding variation in volunteering effort would enable conservation organizations to account for volunteer labor in their strategic planning. We examined variation in volunteering effort across 59 small protected areas managed by Yorkshire Wildlife Trust, a regional conservation nonprofit in the United Kingdom. Three surveys of volunteering effort reveal consistent patterns of variation across protected areas. Using the most detailed of these sources, a survey of site managers, we estimate that volunteers provided 3200 days of labor per year across the 59 sites with a total value exceeding that of paid staff time spent managing the sites. The median percentage by which volunteer labor supplements management costs on the sites was 36%. Volunteering effort and paid management costs are positively correlated, after controlling for the effect of site area. We examined how well a range of characteristics of the protected areas and surrounding communities explain variation in volunteering effort. Protected areas that are larger have been protected for longer and that are located near to denser conurbations experience greater volunteering effort. Together these factors explain 38% of the observed variation in volunteering effort across protected areas.

    Full Text Available Secnidazole is an antimicrobial agent used primarily in the treatment of amoebiasis. For this bioequivalence study of secnidazole, twenty-eight healthy female volunteers were enrolled in a randomized crossover study. Each volunteer was given a single oral dose of secnidazole test preparation and then the reference preparation, or vice versa, with a wash out interval of two weeks. The plasma concentrations of secnidazole were determined by HPLC, and the samples were extracted with tert-butyl-methyl-ether: dicloromethane (60:40, v/v. Secnidazole and its parent compound metronidazole were separated on a C18 column with water:acetonitrile (85:15, v/v as the mobile phase, and monitored at 310 nm.

    Is identity an important predictor of social behavior? The present longitudinal study is focused on identity in order to understand why people continue to volunteer over an extended period of time. The theory of planned behavior and the role identity model of volunteering are used as theoretical framework. Two hundred thirty Italian volunteers were sampled and followed for 3 years. We analyzed functions of role identity as a volunteer. Results showed a significant impact of role identity in predicting volunteer performance after 3 years, mediated through behavioral intentions. Role identity fully mediated the relationships between behavioral intention and attitude, social norms, past behavior and parental modelling.

    Volunteers in palliative care play a key role, particularly in the hospice setting. The expansion of palliative care into developing countries has been accompanied by the emergence of volunteer workers, who are providing a main source of support and care for patients, many of whom never see a health professional. The aim of this study was to evaluate the motivation for becoming a volunteer and the personal impact of being a palliative care Community Volunteer Worker in Uganda. A qualitative methodology using semi-structured individual and group digitally recorded interviews was adopted for the study. Data were analysed for emerging themes using thematic analysis. Forty-three interviews were undertaken, 32 with Community Volunteer Workers and 11 with the Hospice clinical teams, using semi-structured digitally recorded individual, group and focus group interviews at the Hospice Africa sites in Uganda. The results identified the cultural wish to help people as a key motivator in becoming a volunteer. Additionally, the volunteers reported having a sense of pride in their volunteering role, and this role had a positive impact on their perceived status in their local community. This model of volunteering is clearly having an impact on the volunteers, both personally and also in terms of how they are treated in their communities. Further research to explore the long-term personal benefits of being a palliative care volunteer is recommended.

    There is an urgent need to identify lifestyle activities that reduce functional decline and dementia associated with population aging. The goals of this article are to review critically the evidence on the benefits associated with formal volunteering among older adults, propose a theoretical model of how volunteering may reduce functional limitations and dementia risk, and offer recommendations for future research. Database searches identified 113 papers on volunteering benefits in older adults, of which 73 were included. Data from descriptive, cross-sectional, and prospective cohort studies, along with 1 randomized controlled trial, most consistently reveal that volunteering is associated with reduced symptoms of depression, better self-reported health, fewer functional limitations, and lower mortality. The extant evidence provides the basis for a model proposing that volunteering increases social, physical, and cognitive activity (to varying degrees depending on characteristics of the volunteer placement) which, through biological and psychological mechanisms, leads to improved functioning; we further propose that these volunteering-related functional improvements should be associated with reduced dementia risk. Recommendations for future research are that studies (a) include more objective measures of psychosocial, physical, and cognitive functioning; (b) integrate qualitative and quantitative methods in prospective study designs; (c) explore further individual differences in the benefits associated with volunteering; (d) include occupational analyses of volunteers' specific jobs in order to identify their social, physical, and cognitive complexity; (e) investigate the independent versus interactive health benefits associated with volunteering relative to engagement in other forms of activity; and (f) examine the relationship between volunteering and dementia risk.

    2014-01-01

    Background International medical volunteering has grown in recent decades. It has the potential to benefit and harm the volunteer and host countries; but there is a paucity of literature on the impacts of international medical volunteering and a need to find ways to optimise the benefits of such placements. Aim In this study, one example of international medical volunteering was examined involving British GPs on short-term placements in Nepal. The intention was to explore the expectations and experiences of the local health workers, volunteers, and host organisation to try and understand what makes volunteer placements work. Design Qualitative study of key informant interviews. Setting Stakeholders of a short-term international medical volunteer (IMV) placement programme in Nepal. Method Key informant interviews were carried out via face-to-face or telephone/internet interviews with five previous volunteers, three representatives from a non-governmental organisation providing placements, and five local health workers in Nepal who had had contact with the IMVs. Interviews were recorded, transcribed, and analysed using standard thematic framework approaches. Results All the stakeholders had their own specific motives for participating in the IMV programme. The relationship between volunteers and the Nepalese health workers was complex and characterised by discrepant and occasionally unrealistic expectations. Managing these different expectations was challenging. Conclusion Contextual issues and cultural differences are important considerations in medical volunteer programmes, and this study highlights the importance of robust preparation pre-placement for the volunteer and host to ensure positive outcomes.

    2017-06-01

    A survey was conducted to examine the frequency, acceptability, and functions of humor between hospice palliative care volunteers and their patients, from the volunteers' perspective. Thirty-two volunteers completed the survey, which was developed for this study. The results revealed that most patients and volunteers initiated humor either "often" or "sometimes" in their interactions. Over half of the volunteers considered humor to be either "very important" or "extremely important" in their interactions with patients (42% and 13%, respectively), with the patient being the determining factor as to whether and when it is appropriate or not (ie, volunteers take their lead from their patients). Volunteers mentioned a number of functions that humor serves within their patient interactions (eg, to relieve tension, to foster relationships/connections, and to distract). Laughter and humor fulfills one of the main goals of hospice palliative care, namely, improving patients' overall quality of life.

    1997-07-01

    A new live oral cholera vaccine, Peru-15, was studied for safety, immunogenicity, and excretion in 2 groups of healthy volunteers. Twelve inpatient volunteers received freshly harvested vaccine in doses of either 10(7) or 10(9) cfu. Subsequently 50 outpatient volunteers received freeze-dried vaccine in doses of 10(8) or 10(9) cfu or placebo in a three-cell, double-masked, placebo-controlled trial. The strain was well tolerated at all dose levels, and it stimulated high levels of vibriocidal antibodies in most inpatient volunteers and in all outpatient volunteers. Although antitoxin responses were less frequent and of lower magnitude than the vibriocidal responses, antitoxin responses were seen in >60% of the outpatient volunteers. About 60% of the volunteers excreted the vaccine in their feces; however, fecal excretion did not correlate with serologic responses. It is concluded that Peru-15 is a safe and immunogenic oral vaccine for cholera.

    To understand the relationship between volunteering and health in the overlooked yet highly engaged working population, adopting a contextualizing balance approach. We hypothesize that volunteering may function as a psychosocial resource, contributing to work-life balance and, ultimately, health. A total of 746 Swiss workers participated in an online survey; 35% (N = 264) were additionally volunteers in a nonprofit organization. We assessed volunteering, work-life balance perceptions, paid job demands, and resources and health outcomes. After controlling for job characteristics, volunteering was associated with less work-life conflict, burnout and stress, and better positive mental health. Results further revealed that balance perceptions partly explained the relationship between volunteering and health. Volunteering, albeit energy and time-consuming, may contribute to a greater sense of balance for people in the workforce, which might, in turn, positively influence health.

  3. Exploring the Relationship Between Public Service Motivation and Formal and Informal Volunteering

    2017-03-01

    Full Text Available In this paper, we apply public service motivation to the ongoing discussion of formal and informal volunteering and whether these are two distinct constructs or variations on the same theme. This exploratory research uses survey data of undergraduate students reporting their participation in both types of volunteering activities. Using structural equation modeling, these formal and informal volunteering activities show different influences on three dimensions of PSM. In addition to PSM, high school volunteering and religiosity have direct effects on rates of formal volunteering, which in turn positively influence the PSM dimensions of civic duty and self-sacrifice. Being an Evangelical Christian is associated with increased informal volunteering, which is positively related to the PSM compassion dimension. These results indicate that the different dimensions of PSM, and how formal and informal volunteering influences them, should be useful tools for scholars and practitioners seeking to understand these distinct types of pro-social behaviors.

    Full Text Available The Spanish Civil War (1936-1939 was the last European war before the start of World War II. The war, an ideological struggle between Francisco Franco and his nationalist supporters, aided by the Germans and Italians, sought to remove from power the Spanish Republic, which was aided by the Soviet Union. On both sides of the conflict were volunteers from many countries, including the United States of America. American volunteers fought on both sides of the war, yet more chose the side of the Republicans.  Many, but not all, were motivated by political beliefs. Others wanted the perceived romance and excitement of battle, or the sense that they were being of help. The volunteers discussed in this study came from all of these categories, with the ones having political motivation the largest group. They detailed their experiences and their views of the war to their friends, families and comrades back home in the United States.  These letters, which come from the Abraham Lincoln Brigade Archives at New York University, form the main part of the study and provide a deeper insight into what these men and women were thinking, as well as providing insight into their desire to fight in Spain. Through their eyes it is possible to gain a deeper understanding of their experiences and their motivations.  For many of them, their experiences in Spain formed an important part of their journey in life.  Some of them remained loyal to the Communist ideology throughout their lives, while others changed their views as the ruthlessness of Stalin became better known.  A modern audience can benefit from a chance to read their thoughts and ideas in an attempt to better understand the events that helped drive the world into the Second World War.

    The pharmacokinetics of teriflunomide [CAS No. 163451-81-8], the metabolite of leflunomide [CAS No. 75706-12-6] has been evaluated in adult human volunteers after oral administration of tablet formulation. However, no published data is available regarding the bioavailability of this in the Indian population. In light of the above, a study was designed to carry out a bioequivalence study of 2 preparations of leflunomide 20 mg in healthy Indian male volunteers.24 healthy male volunteers (age, 25±4.1 years; weight, 57.58±7.01 kg) were enrolled in this study. Each subject received a test and reference formulation in a single dose, fasting 2 period, 2 way crossover study with a wash out period of 4 weeks. Analysis of teriflunomide from plasma samples was done by a simple and sensitive HPLC method using UV detection developed in our laboratory. An analysis of variance was performed on the pharmacokinetic parameters Cmax, AUC0-t, AUC0-∞ using GLM procedures in which sources of variation were subject, formulation, and period.The results indicated that there are no statistically significant differences between the 2 products in either the mean concentration-time profiles or in the obtained pharmacokinetic parameters. 90% confidence limits for the log transformed data of Cmax, AUC0-t, AUC0-∞. were within the acceptable range of 0.80-1.25.The results indicate that the 2 products are bioequivalent in terms of rate and extent of drug absorption. Both the preparations were well tolerated with no adverse reactions throughout the study.

    Volunteer service opportunities for older adults may soon be expanded. Although volunteering is thought to provide health benefits for healthier older adults, it is not known whether older adults in less than very good health are suitable candidates for high-intensity volunteering and can derive health benefits. This manuscript presents a prospective analysis of 174 older adult volunteers serving in Experience Corps Baltimore, a high-intensity senior volunteer program in Baltimore, Maryland. Volunteers served > or =15 h per week, for a full school year, in elementary schools helping children with reading and other skills between 1999 and 2002. Volunteers were assessed with standardized questionnaires and performance-based testing including grip strength, walking speed, chair stand speed, and stair-climbing speed prior to school volunteering and at the end of the school year. Results were stratified by health status. Among 174 volunteers, 55% initially reported "good" and 12% "fair" or "poor" health status. At baseline, those in fair health reported higher frequencies of disease and disability than volunteers in excellent or very good health. After volunteering, a majority of volunteers in every baseline health status category described increased strength and energy. Those in fair health were significantly more likely to display improved stair-climbing speed than those in good or excellent/very good health (100.0% vs. 53.4% vs. 37.5%, p = 0.05), and many showed clinically significant increases in walking speed of >0.5 m/s. Satisfaction and retention rates were high for all health status groups. Clinicians should consider whether their patients in fair or good health, as well as those in better health, might benefit from high-intensity volunteer programs. Productive activity such as volunteering may be an effective community-based approach to health promotion for older adults.

    Full Text Available Seamus Byrne's Design for a Headstone (1950 and Brian Friel's Volunteers (1975 are some of the most controversial plays in the canon of Irish drama, exceptional in their explicit political implications. Loosely based on the role of the IRA in the Republic, they achieve a high degree of universality in their discussion of such provocative issues as political radicalism, internment, hunger strike, the role of the Church in society, passive resistance vs. active rebellion, justice vs. humanity, and loyalty vs. betrayal. In their tragic endings, both plays reveal a deep pessimism on the part of their authors.

    A two way, randomized cross-over bioequivalence study was conducted to analyse the rate and extent of absorption of atorvastatin after a single dose of 80 mg atorvastatin as atorvastatin calcium tablets. The study was carried out using healthy male volunteers (N = 24). A high performance liquid chromatography method was employed to determine the level of drug in human plasma. It was concluded that the test and the reference drug exhibited comparable values of pharmacokinetic parameters. It was also concluded that since there was no significant difference between the rate and extent of absorption of the drug from the test and the reference formulations: these two formulations could thus be declared bioequivalent.

    2017-01-01

    Full Text Available Background: A volunteer programme with 50 registered volunteers was established in 2007 at a secondary-level public, semi-rural regional hospital in the Cape Winelands, South Africa. This was a rapid response to the extensive renovations and system changes brought about by the hospital revitalisation initiated in 2006 and the resultant expanded services, which required additional human resources. This study describes the hospital volunteer programme and provides hospital administrators with practical planning guidance for hospital volunteer programme implementation.Purpose: The purpose of this study is to (1 describe the outcomes of the hospital volunteer programme implementation intervention and (2 to make sound recommendations for volunteer programme implementation.Methodology and approach: A qualitative case-study methodology was employed using purposive sampling as a technique. Participants were recruited from a public hospital in the Western Cape. A case-study design was applied to explore the hospital volunteer programme implementation. In-depth interviews and a focus group discussion with thematic content analysis of transcripts as well as document reviews were conducted to conclude the study during 2015. The key participants were individually interviewed and included two members of the hospital management, two volunteers and one volunteer coordinator. A focus group discussion consisting of three volunteers was also conducted.Findings: The findings of this study indicate that a volunteer programme can meet needs and be a motivational force for both the individual volunteer and the organisation. However, it requires co-ordination and some secure funding to remain sustainable. Such a programme holds huge benefits in terms of human resource supplementation, organisational development, as well as the possibility of gainful employment for the previously unemployed.Practical implications: In practice, a health service contemplating a volunteer

  18. MDMA Impairs Response to Water Intake in Healthy Volunteers

    2016-01-01

    Full Text Available Hyponatremia is a serious complication of 3,4-methylenedioxymethamphetamine (MDMA use. We investigated potential mechanisms in two double-blind, placebo-controlled studies. In Study 1, healthy drug-experienced volunteers received MDMA or placebo alone and in combination with the alpha-1 adrenergic inverse agonist prazosin, used as a positive control to release antidiuretic hormone (ADH. In Study 2, volunteers received MDMA or placebo followed by standardized water intake. MDMA lowered serum sodium but did not increase ADH or copeptin, although the control prazosin did increase ADH. Water loading reduced serum sodium more after MDMA than after placebo. There was a trend for women to have lower baseline serum sodium than men, but there were no significant interactions with drug condition. Combining studies, MDMA potentiated the ability of water to lower serum sodium. Thus, hyponatremia appears to be a significant risk when hypotonic fluids are consumed during MDMA use. Clinical trials and events where MDMA use is common should anticipate and mitigate this risk.

  19. 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.

  20. Optional contributions have positive effects for volunteering public goods games

    Public goods (PG) games with the volunteering mechanism are referred to as volunteering public goods (VPG) games, in which loners are introduced to the PG games, and a loner obtains a constant payoff but not participating the game. Considering that small contributions may have positive effects to encourage more players with bounded rationality to contribute, this paper introduces optional contributions (high value or low value) to these typical VPG games-a cooperator can contribute a high or low payoff to the public pools. With the low contribution, the logit dynamics show that cooperation can be promoted in a well mixed population comparing to the typical VPG games, furthermore, as the multiplication factor is greater than a threshold, the average payoff of the population is also enhanced. In spatial VPG games, we introduce a new adjusting mechanism that is an approximation to best response. Some results in agreement with the prediction of the logit dynamics are found. These simulation results reveal that for VPG games the option of low contributions may be a better method to stimulate the growth of cooperation frequency and the average payoff of the population.

    Full Text Available BACKGROUND: To convert first-time blood donors into regular volunteer donors is a challenge to transfusion services. OBJECTIVES: This study aims to estimate the return rate of first time donors of the Ribeirão Preto Blood Center and of other blood centers in its coverage region. METHODS: The histories of 115,553 volunteer donors between 1996 and 2005 were analyzed. Statistical analysis was based on a parametric long-term survival model that allows an estimation of the proportion of donors who never return for further donations. RESULTS: Only 40% of individuals return within one year after the first donation and 53% return within two years. It is estimated that 30% never return to donate. Higher return rates were observed among Black donors. No significant difference was found in non-return rates regarding gender, blood type, Rh blood group and blood collection unit. CONCLUSIONS: The low percentage of first-time donors who return for further blood donation reinforces the need for marketing actions and strategies aimed at increasing the return rates.

    Flatulence can cause discomfort and distress but there are few published data of normal patterns and volumes. Twenty four hour collections were made using a rectal catheter in 10 normal volunteers taking their normal diet plus 200 g baked beans. Total daily volume ranged from 476 to 1491 ml (median 705 ml). Women and men (both n = 5) expelled equivalent amounts. The median daily flatus hydrogen volume was 361 ml/24 h (range 42-1060) and the carbon dioxide volume 68 ml/24 h (range 25-116), three volunteers produced methane (3, 26, and 120 ml/24 h), and the remaining unidentified gas (presumably nitrogen) or gases contributed a median 213 ml/24 h (range 61-476). Larger volumes of flatus were produced after meals than at other times. Flatus produced at a faster rate tended to contain more fermentation gases. Flatus was produced during the sleeping period, but the rate was significantly lower than the daytime rate (median 16 and 34 ml/h respectively). Ingestion of a 'fibre free' diet (Fortisip) for 48 hours significantly reduced the total volume collected in 24 hours (median 214 ml/24 h), reduced the carbon dioxide volume (median 6 ml/24 h), and practically eradicated hydrogen production. The volume of unidentified gas was not significantly affected (median 207 ml/24 h). Thus fermentation gases make the highest contribution to normal flatus volume. A 'fibre free' diet eliminates these without changing residual gas release of around 200 ml/24 h. PMID:1648028

    To evaluate the spectrum and frequency of MR findings of the first metatarsophalangeal joint (MTPJ) in asymptomatic volunteers. MR imaging of 30 asymptomatic forefeet was performed with a dedicated extremity 1.5-Tesla system. Participants were between 20 and 49 years of age (mean ± SD: 35.5 ± 8.4 years). Two radiologists assessed cartilage, bone, capsuloligamentous structures, and tendons of first MTPJs on MR images. Cartilage defects were observed in 27 % (n = 8) of first MTPJs, most frequently located at the base of the proximal phalanx (23 %, n = 7), whereas cartilage defects of the metatarsal head (13 %, n = 4) and the metatarsosesamoid compartment were rare (0 %-3 %, n = 0-1). Bone marrow oedema-like signal changes were present in 37 % (n = 11) and subchondral cysts in 20 % (n = 6) of first MTPJs. Hyperintense areas on intermediate-weighted sequences (range: 30-43 %, n = 9-13) and on fluid-sensitive sequences with fat suppression (range: 33-60 %, n = 10-18) within the medial and lateral collateral ligament complex were common. Plantar recesses (77 %, n = 23) and distal dorsal recesses (87 %, n = 26) were frequently observed. Cartilage defects, bone marrow oedema-like signal changes, subchondral cysts, plantar recesses, and distal dorsal recesses were common findings on MRI of first MTPJs in asymptomatic volunteers. The collateral ligaments were often heterogeneous in structure and showed increased signal intensity. (orig.)

    The aim of this study was to investigate whether a tympanic displacement analyser could detect decreases in cerebral blood flow and intracranial pressure after administration of indomethacin in healthy volunteers. In a double-blind crossover study involving 14 healthy volunteers all subjects first underwent a test-retest evaluation to investigate reproducibility followed by tests performed in sitting and supine positions to confirm intracranial-cochlear pressure transfer. In two further sessions tests were performed before and 90 min after subjects were blindly administered a suppository containing either 100 mg of indomethacin or placebo. It was found that tympanic membrane analysis performed 90 min after administration of such a suppository did not mirror the induced reduction in cerebral blood flow after administration of active drug. After administration of indomethacin eight of the subjects experienced discomfort and dizziness; after placebo none experienced subjective symptoms. After administration of indomethacin a statistically significant decrease in heart rate was demonstrated. The exponential form of the intracranial pressure-volume curve may explain why a decrease in intracranial pressure was not detected using the tympanic membrane displacement method, because the measurements were made in subjects with normal intracranial pressure. More significant findings may be found in patients with elevated intracranial pressure.

    Full Text Available Introduction: Bioterrorism is a worldwide problem and has been the focus of attention during recent decades. There is no precise information on the knowledge, attitude, and preparedness of Iranian Red Crescent volunteers in dealing with bioterrorism. Therefore, the present study aimed to evaluate the above-mentioned parameters in Mahabad Red Crescent Society volunteers. Methods: In this prospective cross-sectional study, the knowledge of 120 volunteers was evaluated and rated as poor, moderate, and good. In addition, attitude of the volunteers and preparedness of Mahabad Red Crescent Society was rated as inappropriate and appropriate using a questionnaire. Results: The mean age of volunteers was 32.0 ± 8.2 years (62.5% male. 2 (1.7% volunteers had good knowledge while 94 (78.3% had no knowledge regarding bioterrorist attack management. Only 1 (0.8%  volunteer had appropriate attitude and 6 (5.0% stated their preparedness for being sent out to the crisis zone. 116 volunteers (96.7% indicated that Mahabad Red Crescent Society has an inappropriate level of preparedness to encounter bioterrorist attacks. Conclusion: The findings of the present study showed poor knowledge and inappropriate attitude of Mahabad Red Crescent Society volunteers in encountering probable bioterrorist attacks. Furthermore, the Red Crescent Society of this town had an inappropriate level of preparedness in the field of bioterrorism from the viewpoint of the studied volunteers.

    Background: The Olympic and Paralympic Games rely heavily on volunteers to provide many essential services, including medical care of athletes. Objective: This preliminary investigation sought to characterise the motivational influences and factors responsible for the satisfaction of Olympic and Paralympic healthcare volunteers. Methods: The 2002 Winter Games polyclinic healthcare volunteers were asked to complete a questionnaire designed to elicit information about their motives for volunteering and the factors that contributed to their satisfaction with their volunteer experience. Results: There was no significant difference in the motivation or satisfaction summary scores based on event worked. There was a strong positive correlation between motivation and satisfaction. Physician respondents had a lower mean motivation score than did non-physician volunteers. Conclusions: There were no significant motivational differences between Olympic and Paralympic volunteers, but there were several differences noted between physician and non-physician volunteers. The 2002 polyclinic volunteers appear to have been motivated by a complex process best described as "enlightened self interest," and all were generally well satisfied with their experience. These results may assist organisers of future Games in selecting appropriately motivated volunteer personnel and creating rewarding work environments for them. PMID:15793078

    Full Text Available Few studies in urban forestry have examined the motivations of urban forestry volunteers. In this research, two social psychological theories (Volunteer Functions Inventory and Volunteer Process Model are utilized to examine motivations for participating in tree planting activities. The Volunteer Functions Inventory can be used to examine the needs, goals and motivations that individuals seek to fulfill through volunteerism. The Volunteer Process Model sheds light on the antecedents, experiences and consequences of volunteerism at multiple levels (individual, interpersonal, organizational, societal. An understanding of volunteer motivations can aid practitioners in the development and implementation of participatory urban forestry programs that are attractive to stakeholders. We conducted a survey of volunteers who participated in a MillionTreesNYC volunteer planting event and a focus group of urban forestry practitioners. Survey results reveal that volunteers have varied motivations and a limited knowledge of the community level impacts of trees. Results from the focus group reveal that providing education about the benefits of trees and maintaining long-term communication with volunteers are frequently used strategies for engagement. However, the public’s lack of knowledge about urban forestry and an inability to connect to audiences are practitioner-identified challenges for recruiting stakeholders to participate in their programs.

To determine the postoperative appearance of the plantar fascia on MR imaging after a fasciotomy has been performed, and to compare the postsurgical appearance of the fascia after an open and endoscopic procedure.< rate at head-abs-p1.lf>Design and patients. Fifteen asymptomatic volunteers (12 women, 3 men; age range 22-49 years, mean age 33 years) with prior fasciotomies for treatment of longstanding plantar fasciitis were studied. Fourteen volunteers had a unilateral release and one volunteer had bilateral releases, allowing for assessment of 16 ankles. Eight fasciotomies were performed through an open incision and eight were performed endoscopically. The average time between surgery and imaging was 24 months (range 11-46 months). The site of surgery was established from the operative reports. Proton density (PD)-weighted and T2-weighted images in three orthogonal planes were obtained on a 1.5-T magnet. In eight studies, T1-weighted sagittal and STIR sagittal images were included. The fascia in each ankle was assessed for morphology and signal intensity. Perifascial soft tissues and bone marrow were assessed for edema. Preoperative MR studies were available in five volunteers.< rate at head-abs-p1.lf>Results. There was no apparent difference in the postoperative appearance of the ankle after an open or endoscopic procedure except for scar formation in the subcutaneous fat which was common after an open procedure (P<0.05). Three ankles had a gap in the fascia (one open, two endoscopic). The plantar fascia measured a mean of 7.0 mm (range 5-10 mm) at the fasciotomy, and 8.3 mm (range 6-12 mm) at the enthesis. At the fasciotomy, 11 of 13 ankles had an indistinct deep contour and 9 of 13 had an indistinct superficial contour. At the enthesis, 13 of 16 ankles had an indistinct deep contour and 6 of 16 had an indistinct superficial contour. Compared with preoperative MR studies there was an average reduction in the fascial thickness at the enthesis of 14

METHODS: Microbiota of selected healthy volunteers from the oral cavity (n=10, the esophagus (n=10, the upper digestive tract (n=20, and the lower digestive tract (n=24 were evaluated through distinct collection methods. Collection methods took into account the different sites, using basic scraping and swabbing techniques, stimulated saliva from the oral cavity, irrigation-aspiration with sterile catheters especially designed for the esophagus, a probe especially designed for upper digestive tract, and a special catheter for the lower digestive tract. RESULTS: (i Mixed microbiota were identified in the oral cavity, predominantly Gram-positive aerobic and anaerobic cocci; (ii transitional flora mainly in the esophagus; (iii Veillonella sp, Lactobacillus sp, and Clostridium sp in the stomach and duodenum; (iv in the jejunum and upper ileum, we observed Bacteroides sp, Proteus sp, and Staphylococcus sp, in addition to Veillonella sp; (v in the colon, the presence of "nonpathogenic" anaerobic bacteria Veillonella sp (average 10(5 UFC indicates the existence of a low oxidation-reduction potential environment, which suggests the possibility of adoption of these bacteria as biological markers of total digestive tract health. CONCLUSIONS: The collection methods were efficient in obtaining adequate samples from each segment of the total digestive tract to reveal the normal microbiota. These procedures are safe and easily reproducible for microbiological studies.OBJETIVO: Padronizar os métodos de coleta do muco do trato digestivo e determinar a microbiota, em voluntários saudáveis no Brasil, coletando amostras da boca, esôfago, estômago, duodeno, jejunos e íleo, c

A total of 31 volunteers completed adapted versions of the Volunteer Functions Inventory and a post-survey as part of a program in which they mentored at-risk elementary school students. Volunteers were more satisfied with theirmentoring experience when their perceived benefits matched their initial motivations, though this did not seem to impact their intentions to mentor again in the future. Volunteers’ motivations tended toward expressing important values or gaining greaterunderstanding, though some younger volunteers were also motivated to gain career-related experience. Implications for school-based mentoring programs are addressed.

  12. Digital detectives and virtual volunteers: Integrating emergent online communities into disaster response operations.

    The demonstration of altruistic behaviours by disaster survivors, and even those observing emergencies from afar, is well documented. Over the past few decades, government-sponsored crisis planning has evolved to include affiliated volunteer agencies, with a general acknowledgment of the need to plan for unaffiliated or spontaneous volunteers. Just as the understanding of the need for volunteers has grown, so too have the ways in which volunteers are able to donate their time and skills. The popularity of social media networks and online communities provide new ways for the public to get involved in disaster response. Public service agencies should be proactive in investigating these emerging platforms and understanding their impacts during crises. Established methods of integrating on-scene volunteers into post-disaster response operations can be used as templates for creating virtual volunteer programmes.

    Midwives for Haiti is an organization that focuses on the education and training of skilled birth attendants in Haiti, a country with a high rate of maternal and infant mortality and where only 26% of births are attended by skilled health workers. Following the 2010 earthquake, Midwives for Haiti received requests to expand services and numerous professional midwives answered the call to volunteer. This author was one of those volunteers. The purpose of the study was: 1) to develop a description of the program's strengths and its deficits in order to determine if there was a need to improve the preparation of volunteers prior to service and 2) to make recommendations aimed at strengthening the volunteers' contributions to the education of Haiti and auxiliary midwives. Three distinct but closely related questionnaires were developed to survey Haitian students, staff midwives, and volunteers who served with Midwives for Haiti. Questions were designed to elicit information about how well the volunteers were prepared for their experience, the effectiveness of translation services, and suggestions for improving the preparation of volunteers and strengthening the education program. Analysis of the surveys of volunteers, staff, midwives, and the Haitian students generated several common themes. The 3 groups agreed that the volunteers made an effective contribution to the program of education and that the volunteer midwives need more preparation prior to serving in Haiti. The 3 groups also agreed on the need for better translators and recommended more structure to the education program. The results of this study are significant to international health care organizations that use volunteer health care professionals to provide services. The results support a growing body of knowledge that international health aid organizations may use to strengthen the preparation, support, and effectiveness of volunteer health providers.

    1988-05-01

    We studied 24 young adult male volunteers experimentally inoculated with type 39 rhinovirus to determine whether the course of viral infection was modified by exposure to moderate levels of ozone (0.3 ppm for 6 h per day) over the 5 days after virus inoculation. No differences in rhinovirus titers in nasal secretions, recruitment of neutrophils into nasal secretions, levels of interferon in nasal lavage fluid, in vitro lymphocyte proliferative responses to rhinovirus antigen, or levels of convalescent serum neutralizing antibody to type 39 rhinovirus were demonstrated in relation to ozone exposure. The level and pattern of ozone exposure used in this experiment had no demonstrable adverse effects on the immune responses necessary to limit and terminate rhinovirus infection of the upper respiratory tract.

    2015-06-01

    Volunteer involvement in biological surveys is becoming common in conservation and ecology, prompting questions on the quality of data collected in such surveys. In a systematic review of the peer-reviewed literature on the quality of data collected by volunteers, we examined the characteristics of volunteers (e.g., age, prior knowledge) and projects (e.g., systematic vs. opportunistic monitoring schemes) that affect data quality with regards to standardization of sampling, accuracy and precision of data collection, spatial and temporal representation of data, and sample size. Most studies (70%, n = 71) focused on the act of data collection. The majority of assessments of volunteer characteristics (58%, n = 93) examined the effect of prior knowledge and experience on quality of the data collected, often by comparing volunteers with experts or professionals, who were usually assumed to collect higher quality data. However, when both groups' data were compared with the same accuracy standard, professional data were more accurate in only 4 of 7 cases. The few studies that measured precision of volunteer and professional data did not conclusively show that professional data were less variable than volunteer data. To improve data quality, studies recommended changes to survey protocols, volunteer training, statistical analyses, and project structure (e.g., volunteer recruitment and retention). © 2015, Society for Conservation Biology.

    The year 2011 was declared the 'European Year of Volunteering' to recognise the contribution volunteers make to society. Such cross-national events reflect the high profile of volunteering and political imperatives to promote it. The purpose of this review is to provide a comprehensive review of current knowledge (articles published between 2005 and 2011) regarding the role of volunteering in improving older people's quality of life (QoL) and to identify areas requiring further research. Volunteering was defined as an activity that is freely chosen, does not involve remuneration and helps or benefits those beyond an individual's immediate family. Our search identified 22 studies and 5 review articles that addressed the benefits of volunteering on older people's quality of life. Most of the research had been conducted in the United States, Canada and Australia using data from longitudinal studies. The majority of the studies concluded that there is a positive association between older people's quality of life and engagement in volunteering. Due to the study designs and the heterogeneity of the research, causality is difficult to demonstrate and the knowledge the studies bring to the subject is variable. This review shows that volunteering may help to maintain and possibly improve some older adults' quality of life. However, there are still major gaps in our understanding of who actually benefits, the social and cultural context of volunteering and its role in reducing health and social inequalities.

    2013-01-01

    Research on the influence of volunteering on mental health outcomes has not placed enough focus on African American female caregivers who are at risk for adverse outcomes such as depression. This study addresses this gap by examining the mechanism through which volunteering might influence depressive symptoms using data collected from 521 African American female caregivers of older adults. Regression results indicate that although volunteering is inversely associated with depressive symptoms, self-esteem mediates this relationship. Findings suggest inclusion in volunteering for African American female caregivers may be relevant to promotion of their mental well-being.

    2014-01-01

    This descriptive study examined the relationship between volunteer activities, depressive symptoms, and feelings of usefulness among older adults using path analysis. Survey data was collected via interview from residents of a continuing care retirement community. Neither feelings of usefulness nor volunteering were directly associated with depressive symptoms. Volunteering was directly associated with feelings of usefulness and indirectly associated with depressive symptoms through total physical activity. Age, fear of falling, pain, physical activity, and physical resilience explained 31% of the variance in depressive symptoms. Engaging in volunteer work may be beneficial for increasing feelings of usefulness and indirectly improving depressive symptoms among older adults.

    Full Text Available This paper describes a quantitative empirical research on the factors influencing volunteers in clown-therapy. The field of the volunteering has social relevance particularly for its positive aspects on social community and on prosocial behavior. However, after a broad literature review on the topic of volunteering, the researcher aims to investigate the specific issue of volunteering in clown-therapy, exploring similarities and differences with voluntary activities in other settings, and analysing motivations and reasons for the choice to become a volunteer. A comparative and statistical approach is the real innovative aspect of this research in that it carried out factor analysis, comparative analysis and overcame the limits of the prior research on volunteering, which had dealt just with some dimensions of the complex phenomenon of volunteering.Finally, the research results confirm the hypothesis that volunteering in general, and volunteering in clown-therapy in particular, is an activity empowering both for the individual and for the entire community.

    In this article, we examine varied attitudes and practices toward volunteering in later life, as shared by a group of 40 retired women. We categorize women based on their engagement in retirement and label the categories according to societal expectations as follows: traditional volunteers as "good," nonvolunteers as "bad," and caregiving volunteers as "unrecognized." Using critical gerontology and a feminist framework, we juxtapose the lived experiences of retired women with a prevailing discourse on successful aging and civic engagement. We advocate for societal recognition of caregiving as a valuable form of volunteering, as well as the need to respect multiple ways in which older women experience and find meaning in later life.

    1995-12-01

    A sample of hospice volunteers (n = 99) was administered the Myers-Briggs Type Indicator (Myers & McCaulley, 1985). Frequencies of types observed were compared to population sample (n = 1,105) frequencies. Results indicated that, as a whole, hospice volunteers preferred extraversion over introversion, intuition over sensing, and feeling over thinking. Analysis of four-and two-letter preference combinations also yielded statistically significant differences. Most notably, the sensing-intuitive function appeared pivotal in determining of hospice volunteering. Suggestions are offered as to why the sensing-intuition function appeared central to hospice volunteering. Results appeared consistent with Jungian personality theory.

    Mads U Werner

    Full Text Available BACKGROUND: Human experimental pain models leading to development of secondary hyperalgesia are used to estimate efficacy of analgesics and antihyperalgesics. The ability to develop an area of secondary hyperalgesia varies substantially between subjects, but little is known about the agreement following repeated measurements. The aim of this study was to determine if the areas of secondary hyperalgesia were consistently robust to be useful for phenotyping subjects, based on their pattern of sensitization by the heat pain models. METHODS: We performed post-hoc analyses of 10 completed healthy volunteer studies (n = 342 [409 repeated measurements]. Three different models were used to induce secondary hyperalgesia to monofilament stimulation: the heat/capsaicin sensitization (H/C, the brief thermal sensitization (BTS, and the burn injury (BI models. Three studies included both the H/C and BTS models. RESULTS: Within-subject compared to between-subject variability was low, and there was substantial strength of agreement between repeated induction-sessions in most studies. The intraclass correlation coefficient (ICC improved little with repeated testing beyond two sessions. There was good agreement in categorizing subjects into 'small area' (1(st quartile [75%] responders: 56-76% of subjects consistently fell into same 'small-area' or 'large-area' category on two consecutive study days. There was moderate to substantial agreement between the areas of secondary hyperalgesia induced on the same day using the H/C (forearm and BTS (thigh models. CONCLUSION: Secondary hyperalgesia induced by experimental heat pain models seem a consistent measure of sensitization in pharmacodynamic and physiological research. The analysis indicates that healthy volunteers can be phenotyped based on their pattern of sensitization by the heat [and heat plus capsaicin] pain models.

Purpose: The objective of this study was to characterize the population pharmacokinetics of olprinone after a single continuous infusion in healthy male volunteers. Methods: We used 500 plasma concentration data points collected from nine healthy male volunteers for the study. The population pharmacokinetic analysis was performed using the nonlinear mixed effect model (NONMEM® software. Results: The time course of plasma concentration of olprinone was best described using a two-compartment model. The final pharmacokinetic parameters were total clearance (7.37 mL/minute/kg, distribution volume of the central compartment (134 mL/kg, intercompartmental clearance (7.75 mL/minute/kg, and distribution volume of the peripheral compartment (275 mL/kg. The interindividual variability in the total clearance was 12.4%, and the residual error variability (exponential and additive were 22.2% and 0.129 (standard deviation. The final pharmacokinetic model was assessed using a bootstrap method and visual predictive check. Conclusion: We developed a population pharmacokinetic model of olprinone in healthy male adults. The bootstrap method and visual predictive check showed that this model was appropriate. Our results might be used to develop the population pharmacokinetic model in patients.

    Full Text Available Background: Shirodhara is a classical and a well-established ayurvedic procedure of slowly and steadily dripping medicated oil or other liquids on the forehead. This procedure induces a relaxed state of awareness that results in a dynamic psycho-somatic balance. Objectives: The objective of the study is to evaluate the psychological and physiological effects of Shirodhara in healthy volunteers by monitoring the rating of mood and levels of stress, electrocardiogram (ECG, electroencephalogram (EEG, and selected biochemical markers of stress. Materials and Methods: The study was conducted in the human pharmacology laboratory. The study design was open labeled, comparing the baseline variables with values after Shirodhara. The subjects (n = 16 chosen were healthy human volunteers who gave an informed consent. Shirodhara was preceded by Abhyanga - whole body massage. The Shirodhara method was standardized for rate of dripping with peristaltic pump and temperature was controlled with a thermostat. Mood and stress levels were assessed by validated rating scales. The pre- and post-Shirodhara ECG and EEG records were evaluated. Results: Student′s paired "t" test was applied to the means + SE of the variables to calculate statistical significance at P <0.05. There was a significant improvement in mood scores and the level of stress (P <0.001. These changes were accompanied by significant decrease in rate of breathing and reduction in diastolic blood pressure along with reduction in heart rate. The relaxed alert state, after Shirodhara, was co-related with an increase in alfa rhythm in EEG. Conclusion : A standardized Shirodhara leads to a state of alert calmness similar to the relaxation response observed in meditation. The clinical benefits observed with Shirodhara in anxiety neurosis, hypertension, and stress aggravation due to chronic degenerative diseases could be mediated through these adaptive physiological effects.

    Little is known about the course of the plasma concentration and the bioavailability of non-steroidal anti-inflammatory drugs (NSAIDs) contained in dermal patches. We compared an etofenamate prototype patch (patent EP 1833471) and a commercially available diclofenac epolamine patch regarding the bioavailability of the active ingredients relative to respective i.m. applications and regarding their plasma concentration-time course. Twenty-four healthy human volunteers were treated using a parallel group design (n = 12 per group) with a single dermal patch (removed after 12 hr) followed (after a latency of 48 hr) by eight consecutive dermal patches every 12 hr to reach steady-state conditions. The patches were generally well tolerated, but one volunteer treated with etofenamate developed an allergic contact dermatitis. After the first patch, Cmax was 0.81 ± 0.11 (mean ± S.E.M.) ng/mL (reached 12 hr after patch removal) for diclofenac and 31.3 ± 3.8 ng/mL for flufenamic acid (reached at patch removal), the main metabolite of etofenamate. Etofenamate was not detectable. After repetitive dosing, trough plasma concentrations after the eighth dose were 1.72 ± 0.32 ng/mL for diclofenac and 48.7 ± 6.6 ng/mL for flufenamic acid. Bioavailabilities (single dose) relative to i.m. applications were 0.22 ± 0.04% for diclofenac and 1.15 ± 0.06% for flufenamic acid. In conclusion, the relative bioavailability (compared to the respective i.m. application) of both drugs is low. The maximal plasma concentrations after topical administration of these drugs are well below the IC50 values for COX-1 and COX-2, explaining the absence of dose-dependent toxicities. © 2017 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

    It is important to understand human kinematics and muscle activation patterns in emergency maneuvers for the design of safety systems and for the further development of human models. The objective of this study was to quantify kinematic behavior and muscle activation in simulated steering tests in several realistic conditions. In total 108 tests were performed with 10 volunteers undergoing purely lateral maneuvers at 5 m/s^2 deceleration or simulated lane change maneuvers at 5 m/s^2 peak acceleration and peak yaw velocity of 25 °/s. Test subjects were seated on a rigid seat and restrained by a 4-point belt with retractor. Driver subjects were instructed to be relaxed or braced and to hold the steering wheel while passenger subjects were instructed to put their hands on their thighs. Subjects were instrumented with photo markers that were tracked with 3D high- speed stereo cameras and with electromyography (EMG) electrodes on 8 muscles. Corridors of head displacement, pitch and roll and displacement of T1, shoulder, elbow, hand and knee were created representing mean response and standard deviation of all subjects. In lane change tests for the passenger configuration significant differences were observed in mean peak of head left lateral displacement between the relaxed and the braced volunteers, i.e. 171 mm (σ=58, n=21) versus 121 mm (σ=46, n=17), respectively. Sitting in a relaxed position led to significantly lower muscle activity of the neck muscles. It was concluded that significantly more upper body motion and lower muscle activity was observed for relaxed subjects than for braced subjects.

    The time courses of key biomarkers of exposure to captan and folpet was assessed in accessible biological matrices of orally exposed volunteers. Ten volunteers ingested 1  mg kg(-1) body weight of captan or folpet. Blood samples were withdrawn at fixed time periods over the 72  h following ingestion and complete urine voids were collected over 96  h post-dosing. The tetrahydrophthalimide (THPI) metabolite of captan along with the phthalimide (PI) and phthalic acid metabolites of folpet were then quantified in these samples. Plasma levels of THPI and PI increased progressively after ingestion, reaching peak values ~10 and 6  h post-dosing, respectively; subsequent elimination phase appeared monophasic with a mean elimination half-life (t(½) ) of 15.7 and 31.5  h, respectively. In urine, elimination rate time courses of PI and phthalic acid evolved in parallel, with respective t(½) of 27.3 and 27.6  h; relatively faster elimination was found for THPI, with mean t(½) of 11.7  h. However, phthalic acid was present in urine in 1000-fold higher amounts than PI. In the 96  h period post-treatment, on average 25% of folpet dose was excreted in urine as phthalic acid as compared with only 0.02% as PI. The corresponding value for THPI was 3.5%. Overall, THPI and PI appear as interesting biomarkers of recent exposure, with relatively short half-lives; their sensitivity to assess exposure in field studies should be further verified. Although not a metabolite specific to folpet, the concomitant use of phthalic acid as a major biomarker of exposure to folpet should also be considered.

    2004-01-01

    Full Text Available Abstract Background Physical inactivity increases the risk of atherosclerosis. However, the molecular mechanisms of this relation are poorly understood. A recent report indicates that endostatin, an endogenous angiostatic factor, inhibits the progression of atherosclerosis, and suggests that reducing intimal and atherosclerotic plaque tissue neovascularization can inhibit the progression atherosclerosis in animal models. We hypothesize that exercise can elevate the circulatory endostatin level. Hence, exercise can protect against one of the mechanisms of atherosclerosis. Results We examined treadmill exercise tests in healthy volunteers to determine the effect of exercise on plasma levels of endostatin and other angiogenic regulators. Oxygen consumption (VO2 was calculated. Plasma levels of endostatin, vascular endothelial growth factor (VEGF, and basic fibroblast growth factor (bFGF were determined using ELISA. The total peak VO2 (L in 7 male subjects was 29.5 ± 17.8 over a 4–10 minute interval of exercise. Basal plasma levels of endostatin (immediately before exercise were 20.3 ± 3.2 pg/ml, the plasma levels increased to 29.3 ± 4.2, 35.2 ± 1.8, and 27.1 ± 2.2 ng/ml, at 0.5, 2, and 6 h, respectively, after exercise. There was a strong linear correlation between increased plasma levels of endostatin (% and the total peak VO2 (L related to exercise (R2 = 0.9388; P Conclusions The results suggest that circulating endostatin can be significantly increased by exercise in proportion to the peak oxygen consumption under physiological conditions in healthy volunteers. These findings may provide new insights into the molecular links between physical inactivity and the risk of angiogenesis dependent diseases such as atherosclerosis.

    Up to this date, there are no reports made about the use of media for recruiting research volunteers in Latin American populations. Given the emergence of clinical research in Ecuador, a study of this kind in the local population will be beneficial for future research, and is probably applicable to other countries in the region. Two public calls were made for a cross-sectional study on cognitive function and diabetes. We only included people between 55 and 65 years of age without previous neurocognitive conditions. We invited individuals through interviews on the radio, television broadcasts and local newspapers, along with social media ads. Each individual was asked about the method by which they learned of the project. We calculated the frequency in which each method was reported and a chi-square test was used to assess gender differences in the results. A total of 274 patients were enrolled in the study, 64.2% are women and 35.8% men. We found that 29.93% learned of it from third persons, 20.8% through radio, 8.76% through social media, 8.39% by newspaper, and 5.11% by television, while a remaining 27.01% had not previously heard of the recruitment call. Methods reported varied significantly between men and women (p = 0.03). Traditional media were the most common method of recruitment, with radio interviews being the most frequently reported. Individually, none of them surpassed the frequency of people learning of the project from other people (snowball effect). Social networks play an important role, exceeding certain traditional media. We have described for the first time in Latin America the use of media as methods to recruit volunteers for research, and the importance of project dissemination by the participants to reach more people.

    2012-12-01

    Full Text Available Abstract Background Much of the literature to date concerning public attitudes towards people with severe mental illness (SMI has focused on negative stereotypes and discriminatory behaviour. However, there also exists a tradition of volunteering with these people, implying a more positive attitude. Groups with positive attitudes and behaviours towards people with SMI have received relatively little attention in research. They merit further attention, as evidence on characteristics and experiences of volunteers may help to promote volunteering. The present paper aims to systematically review the literature reporting characteristics, motivations, experiences, and benefits of volunteers in the care of people with SMI. Methods In November 2010, a systematic electronic search was carried out in BNI, CINAHL, Embase, Medline, PsycINFO, Cochrane Registers and Web of Science databases, using a combination of ‘volunteer’, ‘mental health’ and ‘outcome’ search terms. A secondary hand search was performed in relevant psychiatric journals, grey literature and references. Results 14 papers met the inclusion criteria for the review, with data on a total of 540 volunteers. The results suggest that volunteers are a mostly female, but otherwise heterogeneous group. Motivations for volunteering are a combination of what they can ‘give’ to others and what they can ‘get’ for themselves. Overall volunteers report positive experiences. The main benefit to persons with a psychiatric illness is the gaining of a companion, who is non-stigmatizing and proactive in increasing their social-community involvement. Conclusions The evidence base for volunteers in care of people with SMI is small and inconsistent. However there are potential implications for both current and future volunteering programmes from the data. As the data suggests that there is no ‘typical’ volunteer, volunteering programmes should recruit individuals from a variety of

  2. Representing Job Scheduling for Volunteer Grid Environment using Online Container Stowage

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Volunteer grid computing comprises of volunteer resources which are unpredictable in nature and as such the scheduling of jobs among these resources could be very uncer-tain. It is also difficult to ensure the successful completion of submitted jobs on volunteer resources as these resources may opt to withdraw from the grid system anytime or there might be a resource failure, which requires job reassignments. However, a careful consideration of future jobs can make scheduling of jobs more reliable on volunteer resources. There are two possibilities; either to forecast the future jobs or to forecast the resource availability by studying the history events. In this paper an attempt has been made to utilize the future job forecasting in improving the job scheduling experience with volunteer grid resources. A scheduling approach is proposed that uses container stowage to allocate the volunteer grid resources based on the jobs submitted. The proposed scheduling approach optimizes the number of resources actively used. The approach presents online container stowage adaptability for scheduling jobs using volun-teer grid resources. The performance has been evaluated by making comparison to other scheduling algorithms adopted in volunteer grid. The simulation results have shown that the pro-posed approach performs better in terms of average turnaround and waiting time in comparison with existing scheduling algo-rithms. The job load forecast also reduced the number of job reassignments.

    Full Text Available The present research tackles the topic of motives as they are developed by volunteers –who offer time-consuming services without expecting any material gains– and specifically the Olympic Volunteers of «Athens 2004». Four hundred-thirty (N = 430 volunteers completed the Scale of Motives, that was adapted in Greek from the functional approach of Omoto et al. (1993 and Chacon et al. (1998, aiming mainly at the testing of the hypothesis that the motives of volunteers who have previous volunteering experience, but also of those who wish (or continue to volunteer after the completion the Olympic Games, will differ from the motives of those volunteers who have not volunteered in the past or who do not aim at providing voluntary work in the future. The results supported the hypothesis, while the modified Greek scale offered high internal consistencies and strong indications of validity. The future review and reapplication of the design of the adapted questionnaire of Motives will likely eliminate any potential weaknesses and will allow the scale to reach full applicability.

    2017-03-01

    Volunteer rice (Oryza sativa L.) grains may differ in physicochemical traits from cultivated rice, which may reduce the quality of harvested rice grain. To evaluate the effect of volunteer rice on cultivated rice, fields were surveyed in Arkansas in 2012. Cropping history that included hybrid cultivars in the previous two years (2010 and 2011) had higher volunteer rice infestation (20%) compared with fields planted previously with inbred rice (5.5%). The total grain yield of rice was reduced by 0.4% for every 1% increase in volunteer rice density. The grain quality did not change in fields planted with the same cultivar for three years. Volunteer rice density of at least 7.6% negatively impacted the head rice and when infestation reached 17.7%, it also reduced the rice grain yield. The protein and amylose contents of rice were not affected until volunteer rice infestation exceeded 30%. Crop rotation systems that include hybrid rice are expected to have higher volunteer rice infestation than systems without hybrid rice. It is predicted that, at 8% infestation, volunteer rice will start to impact head rice yield and will reduce total yield at 18% infestation. It could alter the chemical quality of rice grain at >30% infestation. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    2009-01-01

    Based on the responses of 5,946 adolescents (mean age = 14.77), the relationships among family influence, adolescents' volunteering intention, and volunteering behavior in a Chinese context were examined. A 9-item Chinese Family Influence on Adolescent Volunteerism Scale (C-FIAV) was used to measure nine kinds of influence of the family (such as family support) which could be subsumed under two underlying domains (positive family influence and extrinsic family influence). Results showed that family support, family belief, and family modeling were positively associated with both intention and behavior. Family reward and coercion were negatively associated with both intention and behavior. Family belief in volunteerism was the most critical factor. Grade and gender differences were found only in the associations between family influence and volunteering intention. Path models showed that positive and extrinsic family influence had an effect on volunteering behavior directly or via the mediation of volunteering intention. Implications and limitations are discussed.

    2016-01-01

    One developmental task in emerging adulthood is finding meaning and purpose in life. Volunteering has been touted as one role that fosters purpose in life. We examined whether the association between frequency of volunteering and purpose in life varies with pleasure-based prosocial motivation and pressure-based prosocial motivation in a sample of 576 undergraduates, ages 18-22 years old. In a regression analysis predicting purpose in life, the frequency of volunteering by pleasure-based prosocial motivation by pressure-based prosocial motivation interaction effect was significant (p = .042). Simple slopes analyses revealed that frequency of volunteering was not significantly (p = .478) related to purpose in life among college students who were low in both pleasure-based and pressure-based prosocial motivation. The findings of the present study highlight the importance of prosocial motivation for understanding whether emerging adults' purpose in life will be enhanced by volunteering.

    2016-01-01

    Volunteers' motives have been differentially linked to various aspects of successful volunteering. Using self-determination theory, we propose that volunteer functions are systematically related to the experience of self-determined versus controlled motivation. This "quality of motivation," in turn, explains why motives are differentially associated with satisfaction. We conducted two studies: Study 1 (N1 = 824) addressed motives, quality of motivation, and satisfaction; Study 2 (N2 = 323) additionally examined function-specific benefits and the extent to which they match volunteers' motives. Overall, our hypotheses were supported: values, understanding, and social justice motives were positively associated with relatively self-determined motivation (RSM), whereas career, social, protective, and enhancement motives showed negative correlations. The relationships between motives and satisfaction were partially mediated by RSM. Concerning benefits, Study 2 corroborated these findings for values, protective, enhancement, and social justice. This research introduces a new perspective on the quality of volunteers' motives-with theoretical and practical implications.

    2007-09-01

    Full Text Available Many youth programs are delivered to provide opportunities for youth to acquire the assets deemed essential to their development into caring, responsible adults. Engaging as a volunteer is considered an experience that provides access to the acquisition of key developmental assets. To date, research has focused on the positive outcomes that can result for adolescent volunteers with little attention being paid to volunteers younger than age 15. This research explored whether and in what ways being a volunteer contributed to the development of youth ages 8 to 12. Interviews were conducted with 73 Boys and Girls Club youth and seven Club Executive Directors in Atlantic Canada. Results indicated that volunteering offered youth an opportunity to serve their communities, care for its members, and feel valued. Younger youth also developed various skills and experienced enhanced self-esteem and self-confidence.

    The cyclonecenter.org project started in fall 2012 and has been collecting citizen scientist volunteer tropical cyclone intensity estimates ever since. The project is hosted by the Citizen Science Alliance (zooniverse) and the platform is supported by a range of scientists. We have over 30 years of satellite imagery of tropical cyclones but the analysis to date has been done on an ocean-basin by ocean-basin basis and worse still practices have changed over time. We therefore do not, presently, have a homogeneous record relevant for discerning climatic changes. Automated techniques can classify many of the images but have a propensity to be challenged during storm transitions. The problem is fundamentally one where many pairs of eyes are invaluable as there is no substitute for human eyes in discerning patterns. Each image is classified by ten unique users before it is retired. This provides a unique insight into the uncertainty inherent in classification. In the three years of the project much useful data has accrued. This presentation shall highlight some of the results and analyses to date and touch on insights as to what has worked and what perhaps has not worked so well. There are still many images left to complete so its far from too late to jump over to www.cyclonecenter.org and help out.

  6. Spatial Collective Intelligence? credibility, accuracy, and Volunteered Geographic Information.

    Collective intelligence is the idea that under the right circumstances collections of individuals are smarter than even the smartest individuals in the group (Suroweiki 2004), that is a group has an "intelligence" that is independent of the intelligence of its members. The ideology of collective intelligence undergirds much of the enthusiasm about the use of "volunteered" or crowdsourced geographic information. Literature from a variety of fields makes clear that not all groups possess collective intelligence, this paper identifies four pre-conditions for the emergence of collective intelligence and then examine the extent to which collectively generated mapping systems satisfy these conditions. However, the "intelligence" collectively generated maps is hard to assess because there are two difficult to reconcile perspectives on map quality- the credibility perspective and the accuracy perspective. Much of the current literature on user generated maps focuses on assessing the quality of individual contributions. However, because user generated maps are complex social systems and because the quality of a contribution is difficult to assess this strategy may not yield an "intelligent" end product. The existing literature on collective intelligence suggests that the structure of groups more important that the intelligence of group members. Applying this idea to user generated suggests that systems should be designed to foster conditions known to produce collective intelligence rather than privileging particular contributions/contributors. The paper concludes with some design recommendations and by considering the implications of collectively generated maps for both expert knowledge and traditional state sponsored mapping programs.

    Full Text Available Successful long-term programs for urban residential food waste sorting are very rare, despite the established urgent need for them in cities for waste reduction, pollution reduction and circular resource economy reasons. This study meets recent calls to bridge policy makers and academics, and calls for more thorough analysis of operational work in terms of behavioral determinants, to move the fields on. It takes a key operational element of a recently reported successful food waste sorting program—manning of the new bins by volunteers—and considers the behavioral determinants involved in order to design a more scalable and cheaper alternative—the use of brightly colored covers with flower designs on three sides of the bin. The two interventions were tested in a medium-scale, real-life experimental set-up that showed that they had statistically similar results: high effective capture rates of 32%–34%, with low contamination rates. The success, low cost and simple implementation of the latter suggests it should be considered for large-scale use. Candidate behavioral determinants are prompts, emotion and knowledge for the yellow bin intervention, and for the volunteer intervention they are additionally social influence, modeling, role clarification, and moderators of messenger type and interpersonal or tailored messaging.

    Taurolidine is an experimental antibacterial and antiendotoxic compound whose clinical utility as an antitumor agent is being investigated in human clinical trials. Taurolidine in aqueous solution exists in equilibrium with taurultam. Taurultam is subsequently transformed to taurinamide. The pharmacokinetic profiles of these metabolites are not well established. In this study, 18 healthy volunteers were administered 5.0 g of taurolidine in 250 mL of 5% polyvinylpyrrolidone in water over 2, 1, or 0.5 hours by intravenous infusion in a parallel-group design. All subjects noted discomfort at the infusion site, although there were no serious adverse events. t(max) generally occurred at the end of infusion for taurinamide, whereas that of taurultam was reached before completion of infusion. The taurolidine metabolite taurultam demonstrated a shorter half-life and lower systemic exposure than taurinamide. Shortening of infusion duration increased the C(max) and AUC of taurultam. Changes in infusion rate did not substantially change the pharmacokinetic parameters of taurinamide.

    Full Text Available Urban neighborhoods are a unique form of geography in that their boundaries rely on a social definition rather than a well-defined physical or administrative boundary. Currently, geographic gazetteers capture little more than then the centroid of a neighborhood, limiting potential applications of the data. In this paper, we present µ-shapes, an algorithm that employs fuzzy-set theory to model neighborhood boundaries suitable for populating gazetteers using volunteered geographic information (VGI. The algorithm is evaluated using a reference dataset and VGI from the Map Kibera Project. A confusion matrix comparison between the reference dataset and µ-shape's output demonstrated high sensitivity and accuracy. Analysis of variance indicated that the algorithm was able to distinguish between boundary and interior blocks. This suggests that, given the existing state of GIS technology, the µ-shapes algorithm can enable neighborhood-related queries that incorporate spatial uncertainty, e.g., find all restaurants within the core of a neighborhood.

  10. VOLUNTEERING FOR CULTURAL HERITAGE CONSERVATION - TWO CASE STUDIES

    Full Text Available A voluntary action is the key for individual benefits in addition to social ones. The voluntary actions for cultural heritage conservation are meant to provide gains for longs terms and to raise public awareness on the importance of conservation-restoration activities. During the past 5 years different volunteering actions for cultural heritage conservation organized by our faculty alone or in cooperation with the ASTRA Museum from Sibiu were finalized with exhibitions and public events. The case study presented in this paper is referring to the conservation-restoration of two long benches with backrest, dating from the first half of XXth century. The benches restored make parts from a group of artefact that was restored in the restoration camps at ASTRA Museum in 2013 and 2014. The particularity of the benches was de finishing layer that imitates the wood texture known as flander technique. This type of finishing is common to the landler community who was deported from Austria to Transylvania at the end of 17th century. The approach of conservations – restorations process was different for the artistic painting parts and needs special and appropriate intervention and investigation. While minimum interventions were making in order to preserve the objects for the future, we want to ensure that the value of less known technique can be well understood by younger generations.

    Full Text Available The present study aimed to investigate the interaction between the blood cells, inflammatory markers, oxidative stress parameters and delayed onset muscle soreness (DOMS after a session of resistance exercise (SRE. The sample consisted of sixteen untrained men (26.4±5 years; 25.9±3 kg m-2. The SRE was composed of 4 sets of 10 repetitions maximum (extensor bench, squat and leg press for each exercise. Complete blood cell count, C-reactive protein (CRP, creatine kinase (CK, lipid peroxidation and antioxidant capacity against peroxyl radicals were previously evaluated (baseline, and at 0, 30 and 120 min. after the SRE. DOMS was assessed 24 hours after the exercises. Immediately after the SRE, an increase of blood cell number was observed; returning to baseline after 30 min. However, after 120 min., neutrophils showed higher values than the baseline and 30 min. assessments. CK and CRP increased progressively throughout the experiment. LPO increased immediately and 120 min. after the SRE. Untrained volunteers presented an apparent biphasic inflammatory response after an acute SRE and the changes in oxidative stress, inflammatory markers and leukocytosis were best evidenced two hours after exercise.

    Full Text Available Abstract Background Pain referral patterns of asymptomatic costotransverse joints have not been established. The objective of this study was to determine the pain referral patterns of asymptomatic costotransverse joints via provocative intra-articular injection. Methods Eight asymptomatic male volunteers received a combined total of 21 intra-articular costotransverse joint injections. Fluoroscopic imaging was used to identify and isolate each costotransverse joint and guide placement of a 25 gauge, 2.5 inch spinal needle into the costotransverse joint. Following contrast medium injection, the quality, intensity, and distribution of the resultant pain produced were recorded. Results Of the 21 costotransverse joint injections, 16 (76% were classified as being intra-articular via arthrograms taken at the time of injection, and 14 of these injections produced a pain sensation distinctly different from that of needle placement. Average pain produced was 3.3/10 on a 0–10 verbal pain scale. Pain was described generally as a deep, dull ache, and pressure sensation. Pain patterns were located superficial to the injected joint, with only the right T2 injections showing referred pain 2 segments cranially and caudally. No chest wall, upper extremity or pseudovisceral pains were reported. Conclusion This study provides preliminary data of the pain referral patterns of costotransverse joints. Further research is needed to compare these findings with those elicited from symptomatic subjects.

    Environmental particle exposure, often estimated as the particulate mass of particles with a diameter environment causes a cellular inflammatory response in the airways of healthy individuals. In the present study, our aim was to investigate potential airway health effects from exposure to a subway environment. 20 healthy volunteers were exposed to a subway and a control environment for 2 h, followed by measurements of lung function and the inflammatory response in the lower airways (bronchoscopy) and in the peripheral blood. No cellular response was found in the airways after exposure to the subway environment. In the blood, we found a statistically significant increase in fibrinogen and regulatory T-cells expressing CD4/CD25/FOXP3. Subway and road tunnel environments have similar levels of PM(10) and PM(2.5), whilst the concentrations of ultrafine particles, nitrogen monoxide and dioxide are lower in the subway. Although no cellular response was detected, the findings indicate a biological response to the subway environment. Our studies show that using gravimetric estimates of ambient particulate air pollution alone may have clear limitations in health-risk assessment.

    Oxygen challenge imaging involves transient hyperoxia applied during deoxyhaemoglobin sensitive (T2*-weighted) magnetic resonance imaging and has the potential to detect changes in brain oxygen extraction. In order to develop optimal practical protocols for oxygen challenge imaging, we investigated the influence of oxygen concentration, cerebral blood flow change, pattern of oxygen administration and field strength on T2*-weighted signal. Eight healthy volunteers underwent multi-parametric magnetic resonance imaging including oxygen challenge imaging and arterial spin labelling using two oxygen concentrations (target FiO2 of 100 and 60%) administered consecutively (two-stage challenge) at both 1.5T and 3T. There was a greater signal increase in grey matter compared to white matter during oxygen challenge (p challenge imaging. Reductions in cerebral blood flow did not obscure the T2*-weighted signal increases. In conclusion, the optimal protocol for further study should utilise target FiO2 = 100% during a single oxygen challenge. Imaging at both 1.5T and 3T is clinically feasible.

  15. Individual heterogeneity and costly punishment: a volunteer's dilemma.

    2013-05-22

    Social control and the enforcement of social norms glue a society together. It has been shown theoretically and empirically that informal punishment of wrongdoers fosters cooperation in human groups. Most of this research has focused on voluntary and uncoordinated punishment carried out by individual group members. However, as punishment is costly, it is an open question as to why humans engage in the punishment of wrongdoers even in one-time-only encounters. While evolved punitive preferences have been advocated as proximate explanations for such behaviour, the strategic nature of the punishment situation has remained underexplored. It has been suggested to conceive of the punishment situation as a volunteer's dilemma (VOD), where only one individual's action is necessary and sufficient to punish the wrongdoer. Here, we show experimentally that implementing the punishment situation as a VOD sustains cooperation in an environment where punishers and non-punishers coexist. Moreover, we show that punishment-cost heterogeneity allows individuals to tacitly agree on only the strongest group member carrying out the punishment, thereby increasing the effectiveness and efficiency of social norm enforcement. Our results corroborate that costly peer punishment can be explained without assuming punitive preferences and show that centralized sanctioning institutions can emerge from arbitrary individual differences.

    Several clinical pharmacokinetic studies of ebrotidine (N-[(E)-[[2-[[[2-[(diaminomethylene)amino]-4-thiazolyl] methyl]thio]ethyl]amino]methylene]-4-bromo-benzenesulfonamide, CAS 100981-43-9, FI-3542) administered by oral route in single and multiple doses to healthy volunteers have been performed. Dosage levels were 150, 300, 400, 500, 600 and 800 mg. Plasma concentrations of unchanged ebrotidine and its major metabolite, ebrotidine sulfoxide, excreted in the urine were determined. The main pharmacokinetic parameters were calculated from the experimental data. Absorption was relatively rapid (Imax = 2 h) and unrelated to dose. Drug behavior was considered as reasonably linear: Cmax = 364-1168 ng/ml and AUC0-12 h = 1427-5997 ng.h/ml (doses from 150 mg to 800 mg). The mean values of terminal elimination half-life (t1/2 beta) ranged from 13.9 to 20.3 h (doses of 400, 600 and 800 mg). After multiple dosing there was no drug accumulation, and no significant changes in the mean values of the main pharmacokinetic parameters were observed. The steady state was reached from the second day of administration, 10-24% of the ebrotidine administered dose was excreted in urine mainly as its major metabolite, ebrotidine sulfoxide, as well as unchanged drug and other minor metabolites. These percentages were constant and independent of the dose administered.

    Determination of the bioequivalence of two ciprofloxacin tablet formulations (test formulation manufactured by Novell Pharmaceutical Laboratories, Indonesia, reference formulation from Quimica Farmaceutica Bayer, Spain). 24 healthy volunteers received each of the two ciprofloxacin formulations at a dose of 500 mg in a 2-way crossover design. Blood samples were obtained prior to dosing and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 and24h after drug administration. Plasma concentrations of ciprofloxacin were monitored using high-performance liquid chromatography over a period of 24 h after administration. The pharmacokinetics parameter AUC0-24h, AUC0-infinity and Cmax were tested for bioequivalence after log-transformation of data and ratios of tmax were evaluated non-parametrically. The point estimates and 90% confidence intervals for AUC0-24h, AUC0-infinity and Cmax were 97.55% (92.71 - 102.6%), 97.63% (92.90 - 102.59%) and 95.84% (89.95 - 102.10%), respectively, satisfying the bioequivalence criteria of the European Committee for Proprietary Medicinal Products and the US Food and Drug Administration guidelines. These results indicate that two medications of ciprofloxacin are bioequivalent and, thus, may be prescribed interchangeably.

    2013: the year that CERN opens its doors to the public. 2013 is also the approximate number of volunteers needed to ensure that these Open Days (JPO) go ahead smoothly. Whatever your personnel status and function, you, the volunteers, are the key without which the Laboratory’s doors could not really open. Sign up now!   1,500 of you volunteered for the LHC2008 open days to mark the inauguration of the LHC. This year, with roughly 20% more visitors expected across the CERN sites over the two days, the organisers envisage closer to 2,000 volunteers. “We will be holding a wide variety of activities across the Laboratory’s various sites,” explains Virginie Blondeau, the member of the Open Days organising team in charge of recruiting and training volunteers. “As well as guides for the experiments, we will also need volunteers to welcome and direct visitors, to help with logistics and to man the sales points, etc.” The volunteers will rec...

    Full Text Available From its’ conception, 4-H has encouraged volunteerism and utilized volunteers to accomplish its’ mission - to assist youth in acquiring knowledge, developing life skills, and forming attitudes that will enable them to become self-directing, productive and contributing members of society. The purpose of this study was to explore and describe the factors that motivated [state] 4-H camp volunteers to volunteer with 4-H youth. The Volunteer Functions Inventory was used as the theoretical base for this study. The Values construct (M=3.68 of the VFI was the highest motivating factor of adult 4-H volunteers. The Understanding construct (M=3.39 ranked the second highest motivational factor in volunteerism followed by Social construct (M=3.28, the Enhancement construct (M = 3.05 and the Protective construct (M=2.78. The Career construct (M=2.61 was the least motivating factor to adult volunteers. It was also found that participants that were not involved with 4-H as a youth volunteered more days per year than did participants who were former 4-H members.

    This study investigated the relationship between the monetary giving and volunteering behavior of adolescents and the role-modeling and conversations about giving provided by their parents. The participants are a large nationally-representative sample of 12-18 year-olds from the Panel Study of Income Dynamics' Child Development Supplement (n = 1244). Adolescents reported whether they gave money and whether they volunteered. In a separate interview parents reported whether they talked to their adolescent about giving. In a third interview, parents reported whether they gave money and volunteered. The results show that both role-modeling and conversations about giving are strongly related to adolescents' giving and volunteering. Knowing that both role-modeling and conversation are strongly related to adolescents' giving and volunteering suggests an often over-looked way for practitioners and policy-makers to nurture giving and volunteering among adults: start earlier, during adolescence, by guiding parents in their role-modeling of, and conversations about, charitable giving and volunteering.

    With the rollout of AIDS therapies, volunteer AIDS care has been promoted across Africa under the assumption that volunteerism is economically imperative in settings of health professional and resource scarcity. As low-income volunteers have become a major part of HIV/AIDS prevention and treatment workforces, it is imperative to question how poverty impacts their well-being. This chapter presents epidemiologic data collected during the 2008 food crisis from a sample of 110 AIDS care volunteers in Addis Ababa, Ethiopia, as well as narratives offered by HIV-positive volunteers, highlighting a widely overlooked way in which food insecurity and mental distress impact efforts to treat AIDS in sub-Saharan Africa. Food insecurity and elevated common mental disorder (CMD) symptom loads were common and tightly linked among the volunteers in the sample. Volunteers who were HIV-positive (17 percent) fared slightly worse in terms of food insecurity and psychosocial well-being. However, positive HIV serostatus was not associated with CMD in multivariate analyses accounting for food insecurity. Narratives illustrate how being HIV-positive shaped experiences of psychosocial stress, which involved unemployment and lack of prospects for marital relationships or strife within them. Our focus demonstrates the potential for mixing ethnographic and epidemiological methods to inform policy questions regarding poverty-reduction through compensation for volunteers' valuable labor, as well as AIDS care program sustainability.

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

    In Circles of Support and Accountability (CoSA), volunteers support a medium- to high-risk sex offender in his process toward desistance by developing a long-term empathic relationship. More knowledge is needed about the impact of this work on volunteers themselves. In a sample of 40 Dutch CoSA volunteers-at the time constituting 37% of the national population of 108 then active CoSA volunteers-we measured outcome in terms of volunteer satisfaction, determination to continue, compassion satisfaction, burnout and secondary stress, vicarious growth, civic capacities, and professional skills. We explored theoretically derived predictors of positive and negative outcome, and conceptualized them within the Job Demands-Resources model (JD-R). Volunteers reported mainly positive effects, especially high levels of volunteer satisfaction, compassion satisfaction, and determination to continue. Results indicated that job demands and most of the internal job resources were of minor importance. External job resources, especially social support and connectedness, were associated with positive outcome. Connectedness mediated the effect of social support on compassion satisfaction.

    A faculty shortage crisis exists in oral and maxillofacial surgery (OMS) education affecting dental students, OMS residents, and OMS full-time faculty. This report was designed to help nonacademic OMS practitioners better understand the problem and appreciate the potential benefits of volunteering as a part-time faculty member. Volunteer part-time faculty can help bolster the efforts of the faculty leaders (full-time and part-time) by taking on some of the dental student and/or resident educational responsibilities. They can also help free up some of the full-time faculty members' time to allow them to complete the scholarly activities required of full-time academicians. Volunteer part-time faculty can greatly benefit from their involvement in dental education. Exposure to faculty leaders and dental students and residents can be educationally enriching and stimulating for volunteer part-time faculty. Students and residents will benefit from learning the differing approaches to patient management that volunteer part-time faculty can provide. In addition, volunteer part-time faculty can have a scope of practice or practice emphasis that differs from and complements that of the faculty leaders. Finally, residents can also benefit from exposure to private practice management strategies that volunteer part-time faculty share. The present report explores how all parties can benefit from OMS faculty volunteerism.

    Firefighters are at increased risk for mental health problems. However, little is known about differences in psychiatric symptoms between volunteer and career firefighters. This study aimed to (1) describe differences in psychiatric symptoms and barriers to mental health care between U.S. firefighters in volunteer-only and career-only departments; and (2) determine if greater self-reported structural barriers to mental health care (e.g., cost, availability of resources) explain the differences in psychiatric symptom levels. Overall, 525 current U.S. firefighters participated. Analyses of covariance and logistic regression analyses were used to evaluate group differences between volunteer (n=204) and career (n=321) firefighters, adjusting for demographic and occupational characteristics. Volunteer firefighters reported significantly elevated levels of depression, posttraumatic stress, and suicidal symptoms compared to career firefighters. Career firefighters reported relatively elevated levels of problematic alcohol use. Volunteer firefighters additionally reported greater structural barriers to mental health care (e.g., cost, availability of resources), and these barriers accounted for the differences in mental health variables between volunteer and career firefighters. Findings suggest that volunteer firefighters report elevated psychiatric symptoms compared to career firefighters and greater structural barriers to mental health treatment may explain this link. Increased efforts are needed to develop firefighter-specific interventions and bolster mental health service utilization. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The aim of this study was to assess the pharmacokinetic profile of pancopride after repeated oral dose administration of 20 mg pancopride in tablet form once a day for 5 d in 12 healthy male volunteers. Plasma levels were measured by HPLC using a solid phase extraction method and automated injection. The minimum quantification limit of pancopride in plasma was 2 ng mL-1. The maximum plasma concentration (mean +/- SD) after the first dose was 92.5 +/- 41.5 ng ML-1 and tmax was 1.7 +/- 0.9 h. The elimination half-life (t1/2) was 14.3 +/- 6.9 h. The area under the concentration-time curve from zero to infinity (AUC) was 997 +/- 396 ng h mL-1. The maximum plasma concentration (mean +/- SD) at steady state (day 5) was 101.8 +/- 36.9 ng mL-1 and tmax was 2.2 +/- 1.2 h. The elimination half-life (t1/2) was 16.3 +/- 2.7 h and the minimum plasma concentration (Cssmin) was 16.6 +/- 6.9 ng mL-1. The area under the concentration-time curve during the dosing interval (AUCss tau) was 995 +/- 389 ng h mL-1. The average plasma concentration at steady state (Cssav) was 43.3 +/- 16.1 ng mL-1 and the experimental accumulation ratio (RAUC) was 1.34 +/- 0.19, whereas the mean theoretical value (R) was 1.40 +/- 0.29. The results obtained showed a good correlation between the experimental plasma levels and the expected values calculated using a repeated dose two-compartment model assessed by means of the Akaike value. It is concluded that the pharmacokinetics of pancopride are not modified after repeated dose administration.(ABSTRACT TRUNCATED AT 250 WORDS)

    Sleep deprivation is common in Western societies and is associated with increased cardiovascular morbidity and mortality in epidemiological studies. However, the effects of partial sleep deprivation on the cardiovascular system are poorly understood. In the present study, we evaluated 13 healthy male volunteers (age: 31 ± 2 yr) monitoring sleep diary and wrist actigraphy during their daily routine for 12 nights. The subjects were randomized and crossover to 5 nights of control sleep (>7 h) or 5 nights of partial sleep deprivation (sleep. At the end of control and partial sleep deprivation periods, heart rate variability (HRV), blood pressure variability (BPV), serum norepinephrine, and venous endothelial function (dorsal hand vein technique) were measured at rest in a supine position. The subjects slept 8.0 ± 0.5 and 4.5 ± 0.3 h during control and partial sleep deprivation periods, respectively (P sleep deprivation caused significant increase in sympathetic activity as evidenced by increase in percent low-frequency (50 ± 15 vs. 59 ± 8) and a decrease in percent high-frequency (50 ± 10 vs. 41 ± 8) components of HRV, increase in low-frequency band of BPV, and increase in serum norepinephrine (119 ± 46 vs. 162 ± 58 ng/ml), as well as a reduction in maximum endothelial dependent venodilatation (100 ± 22 vs. 41 ± 20%; P sleep deprivation is sufficient to cause significant increase in sympathetic activity and venous endothelial dysfunction. These results may help to explain the association between short sleep and increased cardiovascular risk in epidemiological studies.

    During the last decade, web technologies and location sensing devices have evolved generating a form of crowdsourcing known as Volunteered Geographic Information (VGI). VGI acted as a platform of spatial data collection, in particular, when a group of public participants are involved in collaborative mapping activities: they work together to collect, share, and use information about geographic features. VGI exploits participants' local knowledge to produce rich data sources. However, the resulting data inherits problematic data classification. In VGI projects, the challenges of data classification are due to the following: (i) data is likely prone to subjective classification, (ii) remote contributions and flexible contribution mechanisms in most projects, and (iii) the uncertainty of spatial data and non-strict definitions of geographic features. These factors lead to various forms of problematic classification: inconsistent, incomplete, and imprecise data classification. This research addresses classification appropriateness. Whether the classification of an entity is appropriate or inappropriate is related to quantitative and/or qualitative observations. Small differences between observations may be not recognizable particularly for non-expert participants. Hence, in this paper, the problem is tackled by developing a rule-guided classification approach. This approach exploits data mining techniques of Association Classification (AC) to extract descriptive (qualitative) rules of specific geographic features. The rules are extracted based on the investigation of qualitative topological relations between target features and their context. Afterwards, the extracted rules are used to develop a recommendation system able to guide participants to the most appropriate classification. The approach proposes two scenarios to guide participants towards enhancing the quality of data classification. An empirical study is conducted to investigate the classification of grass

    Full Text Available AbstractBalance deteriorates with age, and may eventually lead to falling accidents which may threaten independent living. As Taekwondo contains various highly dynamic movement patterns, taekwondo practice may sustain or improve balance. Therefore, in 24 middle-aged healthy volunteers (40-71 year we investigated effects of age-adapted taekwondo training of one hour a week during one year on various balance parameters, such as: motor orientation ability (primary outcome measure, postural and static balance test, single leg stance, one leg hop test, and a questionnaire.Motor orientation ability significantly increased in favor of the antero-posterior direction with a difference of 0.62 degrees towards anterior compared to pre-training measurement, when participants corrected the tilted platform rather towards the posterior direction; female gender being an independent outcome predictor. On postural balance measurements sway path improved in all 19 participants, with a median of 9.3 mm/sec (range 0.71-45.86, and sway area in 15 participants with 4.2 mm²/sec (range 17.39-1.22. Static balance improved with an average of 5.34 seconds for the right leg, and with almost 4 seconds for the left. Median single leg stance duration increased in 17 participants with 5 seconds (range 1-16, and in 13 participants with 8 seconds (range 1-18. The average one leg hop test distance increased (not statistically significant with 9.5 cm. The questionnaire reported a better ‘ability to maintain balance’ in sixteen.In conclusion, our data suggest that age-adapted Taekwondo training improves various aspects of balance control in healthy people over the age of forty.

    Balance deteriorates with age, and may eventually lead to falling accidents which may threaten independent living. As Taekwondo contains various highly dynamic movement patterns, Taekwondo practice may sustain or improve balance. Therefore, in 24 middle-aged healthy volunteers (40-71 year) we investigated effects of age-adapted Taekwondo training of 1 h a week during 1 year on various balance parameters, such as: motor orientation ability (primary outcome measure), postural and static balance test, single leg stance, one leg hop test, and a questionnaire. Motor orientation ability significantly increased in favor of the antero-posterior direction with a difference of 0.62° toward anterior compared to pre-training measurement, when participants corrected the tilted platform rather toward the posterior direction; female gender being an independent outcome predictor. On postural balance measurements sway path improved in all 19 participants, with a median of 9.3 mm/s (range 0.71-45.86), and sway area in 15 participants with 4.2 mm(2)/s (range 17.39-1.22). Static balance improved with an average of 5.34 s for the right leg, and with almost 4 s for the left. Median single leg stance duration increased in 17 participants with 5 s (range 1-16), and in 13 participants with 8 s (range 1-18). The average one leg hop test distance increased (not statistically significant) with 9.5 cm. The questionnaire reported a better "ability to maintain balance" in 16. In conclusion, our data suggest that age-adapted Taekwondo training improves various aspects of balance control in healthy people over the age of 40.

    Postprandial glucose (PPG) is an independent predictor of cardiovascular events and death, regardless of diabetes status. Whereas changes in physical activity produce changes in insulin sensitivity, it is not clear whether changes in daily physical activity directly affect PPG in healthy free-living persons. We used continuous glucose monitors to measure PPG and PPG excursions (ΔPPG, postmeal - premeal blood glucose) at 30-min increments after meals in healthy habitually active volunteers (n = 12, age = 29 ± 1 yr, body mass index = 23.6 ± 0.9 kg·m(-2), VO2max = 53.6 ± 3.0 mL·kg(-1)·min(-1)) during 3 d of habitual (≥10,000 steps per day) and reduced (physical activity. Diets were standardized across monitoring periods, and fasting-state oral glucose tolerance tests (OGTT) were performed on the fourth day of each monitoring period. During 3 d of reduced physical activity (12,956 ± 769 to 4319 ± 256 steps per day), PPG increased at 30 and 60 min after a meal (6.31 ± 0.19 to 6.68 ± 0.23 mmol·L(-1) and 5.75 ± 0.16 to 6.26 ± 0.28 mmol·L(-1), P active time point), and ΔPPG increased by 42%, 97%, and 33% at 30, 60, and 90 min after a meal, respectively (P activity (P physical activity in otherwise healthy free-living individuals. These data indicate that daily physical activity is an important mediator of glycemic control, even among healthy individuals, and reinforce the utility of physical activity in preventing pathologies associated with elevated PPG.

    Because children who have been receiving stiripentol for the treatment of Dravet syndrome for more than 10 years are now becoming young adults, it is important to accurately characterize stiripentol pharmacokinetics in this age range. A double-blind placebo-controlled dose ranging study was therefore conducted to investigate the pharmacokinetics and tolerability of stiripentol in 12 healthy volunteers. Each subject received 3 single doses of stiripentol (500, 1000, and 2000 mg) separated by a wash-out period of 1 week. Pharmacokinetics of stiripentol was analyzed for each dose by non-compartmental analysis. Median area under the curve (AUC), terminal elimination half-life (t1/2,z) and maximal concentration (Cmax) were calculated for between-dose comparison. Safety was evaluated based on both clinical and biological criteria. Oppositely to previous results, there was no concentration rebounds in the elimination phase, which could be the consequence of the food intake. A more than proportional increase in the AUC was observed, associated with a significant increase in the t1/2,z, for increasing doses (median AUC of 8.3, 31 and 88 mgh/L, and median t1/2,z of 2, 7.7 and 10h for the 500, 1000, and 2000 mg doses respectively), which confirmed the Michaelis-Menten pharmacokinetics of Stiripentol. However, dose-normalized Cmax did not significantly vary between doses. Median Michaelis-Menten parameters were 117 mg/h for Vmax and 1.9 mg/L for Km. No safety concern was observed during the study. The present study allowed a better characterization of the disposition phase of stiripentol and confirmed its non-linear pharmacokinetic behaviour. Further pharmacokinetic/pharmacodynamic studies would be useful to determine the optimal dose of stiripentol for the treatment of Dravet patients in adulthood.

    To better assess biomonitoring data in workers exposed to captan and folpet, the kinetics of ring metabolites [tetrahydrophthalimide (THPI), phthalimide (PI) and phthalic acid] were determined in urine and plasma of dermally exposed volunteers. A 10  mg kg(-1) dose of each fungicide was applied on 80  cm(2) of the forearm and left without occlusion or washing for 24  h. Blood samples were withdrawn at fixed time periods over the 72  h following application and complete urine voids were collected over 96  h post-dosing, for metabolite analysis. In the hours following treatment, a progressive increase in plasma levels of THPI and PI was observed, with peak levels being reached at 24  h for THPI and 10  h for PI. The ensuing elimination phase appeared monophasic with a mean elimination half-life (t(½) ) of 24.7 and 29.7 h for THPI and PI, respectively. In urine, time courses PI and phthalic acid excretion rate rapidly evolved in parallel, and a mean elimination t(½) of 28.8 and 29.6  h, respectively, was calculated from these curves. THPI was eliminated slightly faster, with a mean t(½) of 18.7  h. Over the 96  h period post-application, metabolites were almost completely excreted, and on average 0.02% of captan dose was recovered in urine as THPI while 1.8% of the folpet dose was excreted as phthalic acid and 0.002% as PI, suggesting a low dermal absorption fraction for both fungicides. This study showed the potential use of THPI, PI and phthalic acid as key biomarkers of exposure to captan and folpet.

    Full Text Available Background and objectives: Regardless of prevailing advances in yoga research, the immediate benefit of chandranadi pranayama (CNP on heart rate variability was not explored. Therefore, in this study, we planned to study the immediate effect of CNP on heart rate, blood pressure and HRV. Methods: One hundred and ten medical students were randomly divided into two groups; control group (n=55 and CNP group (n=55. CNP group participants were individually trained to perform CNP by an experienced yoga instructor with a regularity of 6 breaths/min for five minutes. CG volunteers didn’t undergo CNP, Pre and post intervention HR, BP measurements and spectral analysis of HRV was done in both the groups. The paired student’s t test was used to determine significant differences. Results: There was a significant decrease in HR (p<0.01, BP (p<0.05, LFnu (p<0.05, LF/HF (p<0.001 and increase in HFnu (p<0.01 followed by five minutes of CNP in CNP group. Further, HR, SBP, DBP was reduced by 9.10%, 4.80%, 7.75 % respectively. HRV results showed 7.59% reduction in LFnu, 17.8% reduction in LF/HF and HF was increased by 12.37%. There were no significant changes in CG. Conclusion: It is concluded that CNP is beneficial in reducing HR, BP and to improve Sympathovagal balance. We advise that this effective method be included with the management protocol of hypertension and utilized when immediate reduction of blood pressure is required in day-to-day as well as clinical situations.

    Objective To evaluate bioavailability and pharmacokinetics of domestic and imported anastrozole tablets. Methods Twenty Chinese healthy male volunteers were enrolled in a randomized crossover study with a single oral dose of 2mg of the two formulations respectively. The anastrozole in plasma was measured by gas chromatography with electron-capture detection. The linear range was 1. 325 ~ 106ng /ml plasma. The extraction recovery rates for plasma concentration of 5.3, 21.2 and 53. Ong/ml were 76.8% ,87.0% and 78.7%, respectively. Inter-day and intra-day precisions of the method were < 9%. Area under concentration-time curve ( AUCo t) , maximum plasma concentration (Cmax) and reach peak time (Tmax) were evaluated by variance analysis and two one-side t-test . Results A two-compartment model was adopted in anastrozole plasma concentration-time data analysis. The main pharmacokinetic parameters of domestic and imported anastrozloe tablets such as Cmax , Tmax, AUCo - t and T1/2β were (36.5 ± 6.9)ng/ml and (35.6 ± 9.4)ng/ml, (1.56-±0.41)hand(1.53 ±0.49)h, (1403.6 ± 321.2)ng'h/mland (1371.6±329.4)ng'h/mi, (42.57 ± 10.15)h and (43.41 ± 8.59)h, respectively, and there were no significant differences between the two formulations. Conclusion Domestic and imported anastrozole tablets were of bioequivalence.The relative bioavailability of the domestic tablet was (102.7 ± 5.6)%.

    The clinical use of therapeutic hypothermia has been rapidly expanding due to evidence of neuroprotection. However, the effect of hypothermia on specific pathways of drug elimination in humans is relatively unknown. To gain insight into the potential effects of hypothermia on drug metabolism and disposition, we evaluated the pharmacokinetics of midazolam as a probe for CYP3A4/5 activity during mild hypothermia in human volunteers. A second objective of this work was to determine whether benzodiazepines and magnesium administered intravenously would facilitate the induction of hypothermia. Subjects were enrolled in a randomized crossover study, which included two mild hypothermia groups (4°C saline infusions and 4°C saline + magnesium) and two normothermia groups (37°C saline infusions and 37°C saline + magnesium). The lowest temperatures achieved in the 4°C saline + magnesium and 4°C saline infusions were 35.4 ± 0.4 and 35.8 ± 0.3°C, respectively. A significant decrease in the formation clearance of the major metabolite 1′-hydroxymidazolam was observed during the 4°C saline + magnesium compared with that in the 37°C saline group (p midazolam. This model predicted that midazolam clearance decreases 11.1% for each degree Celsius reduction in core temperature from 36.5°C. Midazolam with magnesium facilitated the induction of hypothermia, but shivering was minimally suppressed. These data provided proof of concept that even mild and short-duration changes in body temperature significantly affect midazolam metabolism. Future studies in patients who receive lower levels and a longer duration of hypothermia are warranted. PMID:20164112

    The effects of intravenously administered midazolam on cerebral blood flow were evaluated in eight healthy volunteers using the /sup 133/Xe inhalation technique. Six minutes after an intravenous dose of 0.15 mg/kg midazolam, the cerebral blood flow decreased significantly (P less than 0.001) from a value of 40.6 +/- 3.3 to a value of 27.0 +/- 5.0 ml . 100 g-1 . min-1. Cerebrovascular resistance (CVR) increased from 2.8 +/- 0.2 to 3.9 to 0.6 mmHg/(ml . 100 g-1 . min-1)(P less than 0.001). Mean arterial blood pressure decreased significantly (P less than 0.05) from 117 +/- 8 to 109 +/- 9 mmHg and arterial carbon dioxide tension increased from 33.9 +/- 2.3 to 38.6 +/- 3.2 mmHg (P less than 0.05). Arterial oxygen tension remained stable throughout the study, 484 +/- 95 mmHg before the administration of midazolam and 453 +/- 76 mmHg after. All the subjects slept after the injection of the drug and had anterograde amnesia of 24.5 +/- 5 min. The decrease in mean arterial blood pressure was probably not important since it remained in the physiologic range for cerebral blood flow autoregulation. The increase in arterial carbon dioxide tension observed after the midazolam injection may have partially counteracted the effect of this new benzodiazepine on cerebral blood flow. Our data suggest that midazolam might be a safe agent to use for the induction of anethesia in neurosurgical patients with intracranial hypertension.
