  1. Volunteered Cloud Computing for Disaster Management

    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

    Abstract Volunteer computing has come up as a new form of distributed computing. Unlike other computing paradigms like Grids, which use to be based on complex architectures, volunteer computing has demonstrated a great ability to integrate dispersed, heterogeneous computing resources with ease. This article presents ZIVIS, a project which aims to deploy a city-wide computing platform in Zaragoza (Spain). ZIVIS is based on BOINC (Berkeley Open Infrastructure for Network Computing), a popular open source framework to deploy volunteer and desktop grid computing systems. A scientific code which simulates the trajectories of particles moving inside a stellarator fusion device, has been chosen as the pilot application of the project. In this paper we describe the approach followed to port the code to the BOINC framework as well as some novel techniques, based on standard Grid protocols, we have used to access the output data present in the BOINC server from a remote visualizer.

    The ATLAS collaboration has setup a volunteer computing project called ATLAS@home. Volunteers running Monte-Carlo simulation on their personal computer provide significant computing resources, but also belong to a community potentially interested in HEP. Four types of contributors have been identified, whose questions range from advanced technical details to the reason why simulation is needed, how Computing is organized and how it relates to society. The creation of relevant outreach material for simulation, event visualization and distributed production will be described, as well as lessons learned while interacting with the BOINC volunteers community.

    ATLAS@Home is a volunteer computing project which allows the public to contribute to computing for the ATLAS experiment through their home or office computers. The project has grown continuously since its creation in mid-2014 and now counts almost 100,000 volunteers. The combined volunteers' resources make up a sizable fraction of overall resources for ATLAS simulation. This paper takes stock of the experience gained so far and describes the next steps in the evolution of the project. These improvements include running natively on Linux to ease the deployment on for example university clusters, using multiple cores inside one job to reduce the memory requirements and running different types of workload such as event generation. In addition to technical details the success of ATLAS@Home as an outreach tool is evaluated.

    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. (paper)

    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 at 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 at 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.

    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.

  13. The context of ethical problems in medical volunteer work.

    2011-06-01

    Ethical problems are common in clinical medicine, so medical volunteers who practice clinical medicine in developing countries should expect to encounter them just as they would in their practice in the developed world. However, as this article argues, medical volunteers in developing countries should not expect to encounter the same ethical problems as those that dominate Western biomedicine or to address ethical problems in the same way as they do in their practice in developed countries. For example, poor health and advanced disease increase the risks and decrease the potential benefits of some interventions. Consequently, when medical volunteers intervene too readily, without considering the nutritional and general health status of patients, the results can be devastating. Medical volunteers cannot assume that the outcomes of interventions in developing countries will be comparable to the outcomes of the same interventions in developed countries. Rather, they must realistically consider the complex medical conditions of patients when determining whether or not to intervene. Similarly, medical volunteers may face the question of whether to provide a pharmaceutical or perform an intervention that is below the acceptable standard of care versus the alternative of doing nothing. This article critically explores the contextual features of medical volunteer work in developing countries that differentiate it from medical practice in developed countries, arguing that this context contributes to the creation of unique ethical problems and affects the way in which these problems should be analyzed and resolved.

    Many nongovernmental organizations in Africa rely on grassroots volunteers to provide critical health services. Considering context and the interplay of individual, organizational, and societal influences on the experience of volunteers, this paper addresses three questions: What do grassroots volunteers contribute? What organizational processes promote volunteer engagement? What are the positive and negative consequences of volunteering? Eighteen members and staff of the Tanzanian HIV and AIDS NGO, KIWAKKUKI, were selected from 6000+ women volunteers to be interviewed. The interviews were recorded, transcribed, and analyzed for themes. Within KIWAKKUKI, volunteers contributed time and local knowledge, leading to an indigenous educational approach building on local norms and customs. Volunteers' engagement was motivated by the desire to support family members, reverse stigma, and work/socialize with other women. Benefits to volunteers included skills acquisition and community recognition; yet some volunteers also reported negative experiences including burnout, conferred stigma, and domestic violence. Positive organizational processes built on cultural practices such as collective decision-making and singing. The findings point to important considerations about context, including the synergistic effect training can have on local traditions of caring, complications of gender inequity, and how community health planning processes may need to be modified in extremely poor settings. This research also suggests good utility of the research framework (the Bergen Model of Collaborative Functioning) that was used to analyze volunteer engagement for service delivery in sub-Saharan contexts. © The Author(s) 2015.

    The exploitation of volunteer computing resources has become a popular practice in the HEP computing community as the huge amount of potential computing power it provides. In the recent HEP experiments, the grid middleware has been used to organize the services and the resources, however it relies heavily on the X.509 authentication, which is contradictory to the untrusted feature of volunteer computing resources, therefore one big challenge to utilize the volunteer computing resources is how to integrate them into the grid middleware in a secure way. The DIRAC interware which is commonly used as the major component of the grid computing infrastructure for several HEP experiments proposes an even bigger challenge to this paradox as its pilot is more closely coupled with operations requiring the X.509 authentication compared to the implementations of pilot in its peer grid interware. The Belle II experiment is a B-factory experiment at KEK, and it uses DIRAC for its distributed computing. In the project of BelleII@home, in order to integrate the volunteer computing resources into the Belle II distributed computing platform in a secure way, we adopted a new approach which detaches the payload running from the Belle II DIRAC pilot which is a customized pilot pulling and processing jobs from the Belle II distributed computing platform, so that the payload can run on volunteer computers without requiring any X.509 authentication. In this approach we developed a gateway service running on a trusted server which handles all the operations requiring the X.509 authentication. So far, we have developed and deployed the prototype of BelleII@home, and tested its full workflow which proves the feasibility of this approach. This approach can also be applied on HPC systems whose work nodes do not have outbound connectivity to interact with the DIRAC system in general.

    Similar to common asymmeric encryption, RSA can be cracked by usmg a series mathematical calculation. The private key used to decrypt the massage can be computed using the public key. However, finding the private key may require a massive amount of calculation. In this paper, we propose a method to perform a distributed computing to calculate RSA’s private key. The proposed method uses multiple volunteered mobile devices to contribute during the calculation process. Our objective is to demonstrate how the use of volunteered computing on mobile devices may be a feasible option to reduce the time required to break a weak RSA encryption and observe the behavior and running time of the application on mobile devices.

    In this research, the study concerns around several features of diagonal Latin squares (DLSs) of small order. Authors of the study suggest an algorithm for computing minimal and maximal numbers of transversals of DLSs. According to this algorithm, all DLSs of a particular order are generated, and for each square all its transversals and diagonal transversals are constructed. The algorithm was implemented and applied to DLSs of order at most 7 on a personal computer. The experiment for order 8 was performed in the volunteer computing project Gerasim@home. In addition, the problem of finding pairs of orthogonal DLSs of order 10 was considered and reduced to Boolean satisfiability problem. The obtained problem turned out to be very hard, therefore it was decomposed into a family of subproblems. In order to solve the problem, the volunteer computing project SAT@home was used. As a result, several dozen pairs of described kind were found.

    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.

    2018-03-01

    This article presents the Templet Web cloud service. The service is designed for high-performance scientific computing automation. The use of high-performance technology is specifically required by new fields of computational science such as data mining, artificial intelligence, machine learning, and others. Cloud technologies provide a significant cost reduction for high-performance scientific applications. The main objectives to achieve this cost reduction in the Templet Web service design are: (a) the implementation of "on-demand" access; (b) source code deployment management; (c) high-performance computing programs development automation. The distinctive feature of the service is the approach mainly used in the field of volunteer computing, when a person who has access to a computer system delegates his access rights to the requesting user. We developed an access procedure, algorithms, and software for utilization of free computational resources of the academic cluster system in line with the methods of volunteer computing. The Templet Web service has been in operation for five years. It has been successfully used for conducting laboratory workshops and solving research problems, some of which are considered in this article. The article also provides an overview of research directions related to service development.

    2018-03-01

    Full Text Available This article presents the Templet Web cloud service. The service is designed for high-performance scientific computing automation. The use of high-performance technology is specifically required by new fields of computational science such as data mining, artificial intelligence, machine learning, and others. Cloud technologies provide a significant cost reduction for high-performance scientific applications. The main objectives to achieve this cost reduction in the Templet Web service design are: (a the implementation of “on-demand” access; (b source code deployment management; (c high-performance computing programs development automation. The distinctive feature of the service is the approach mainly used in the field of volunteer computing, when a person who has access to a computer system delegates his access rights to the requesting user. We developed an access procedure, algorithms, and software for utilization of free computational resources of the academic cluster system in line with the methods of volunteer computing. The Templet Web service has been in operation for five years. It has been successfully used for conducting laboratory workshops and solving research problems, some of which are considered in this article. The article also provides an overview of research directions related to service development.

    Bioinformatics is an interdisciplinary research field that develops tools for the analysis of large biological databases, and, thus, the use of high performance computing (HPC) platforms is mandatory for the generation of useful biological knowledge. The latest generation of graphics processing units (GPUs) has democratized the use of HPC as they push desktop computers to cluster-level performance. Many applications within this field have been developed to leverage these powerful and low-cost architectures. However, these applications still need to scale to larger GPU-based systems to enable remarkable advances in the fields of healthcare, drug discovery, genome research, etc. The inclusion of GPUs in HPC systems exacerbates power and temperature issues, increasing the total cost of ownership (TCO). This paper explores the benefits of volunteer computing to scale bioinformatics applications as an alternative to own large GPU-based local infrastructures. We use as a benchmark a GPU-based drug discovery application called BINDSURF that their computational requirements go beyond a single desktop machine. Volunteer computing is presented as a cheap and valid HPC system for those bioinformatics applications that need to process huge amounts of data and where the response time is not a critical factor.

    USPEX is a world-leading software for computational material design. In essence, USPEX splits simulation into a large number of workunits that can be processed independently. This scheme ideally fits the desktop grid architecture. Workunit processing is done by a simulation package aimed at energy minimization. Many of such packages are proprietary and should be protected from unauthorized access when running on a volunteer PC. In this paper we present an original approach based on virtualization. In a nutshell, the proprietary code and input files are stored in an encrypted folder and run inside a virtual machine image that is also password protected. The paper describes this approach in detail and discusses its application in USPEX@home volunteer project.

    We carried out qualitative research with 61 health professionals and volunteer workers to explore their perceptions of their own and their clients' well-being in a context of political violence. We applied content analysis to identify the themes emerging from 8 focus group and 11 individual interviews. Participants were found to define the concept of well-being in terms of three key areas: security, participation, and development. Palestinian health providers see promotion of economic development and professional growth, involvement in political and social life, and resistance to the occupation as factors required to enhance well-being and quality of life for themselves and their clients.

    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. PMID:21994824

    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.

    Computing for the LHC, and for HEP more generally, is traditionally viewed as requiring specialized infrastructure and software environments, and therefore not compatible with the recent trend in v olunteer computing , where volunteers supply free processing time on ordinary PCs and laptops via standard Internet connections. In this paper, we demonstrate that with the use of virtual machine technology, at least some standard LHC computing tasks can be tackled with volunteer computing resources. Specifically, by presenting volunteer computing resources to HEP scientists as a v olunteer cloud , essentially identical to a Grid or dedicated cluster from a job submission perspective, LHC simulations can be processed effectively. This article outlines both the technical steps required for such a solution and the implications for LHC computing as well as for LHC public outreach and for participation by scientists from developing regions in LHC research.

    Faced with aging societies, there is an immense need to better understand the nature of volunteering outside advanced Western industrial countries. As a case of a rapidly aging society, we identify robust factors associated with elderly volunteering in Korea in terms of a resource framework. Data were derived from the Social Statistics Survey conducted by the Korea National Statistical Office in 1999 (N = 7,135) and 2003 (N = 8,371). We first determined overall and age-related volunteer rates for Korea compared to the United States. Using logistic regression, we then examined the effects of human, cultural, and social capital variables on volunteering. Approximately 6% of Koreans aged 65 years and older participate in volunteer programs. All human capital variables are positively related with volunteering. For cultural capital, those who identify their religion as Buddhism or Catholicism are more likely to volunteer than those who have no religion. But surprisingly, Protestantism does not consistently promote volunteering across both years. For social capital, older adults who live alone or with a spouse are more likely to volunteer than those living with both a spouse and children. In contrast to human capital, cultural and social capital on elderly volunteering appears to be contoured by social contexts.

    We present the prototype of a context-aware framework that allows users to control smart home devices and to access internet services via a Hybrid BCI system of an auto-calibrating sensorimotor rhythm (SMR) based BCI and another assistive device (Integra Mouse mouth joystick). While there is extensive literature that describes the merit of Hybrid BCIs, auto-calibrating and co-adaptive ERD BCI training paradigms, specialized BCI user interfaces, context-awareness and smart home control, there is up to now, no system that includes all these concepts in one integrated easy-to-use framework that can truly benefit individuals with severe functional disabilities by increasing independence and social inclusion. Here we integrate all these technologies in a prototype framework that does not require expert knowledge or excess time for calibration. In a first pilot-study, 3 healthy volunteers successfully operated the system using input signals from an ERD BCI and an Integra Mouse and reached average positive predictive values (PPV) of 72 and 98% respectively. Based on what we learned here we are planning to improve the system for a test with a larger number of healthy volunteers so we can soon bring the system to benefit individuals with severe functional disability.

  12. Corporate volunteering - motivation for voluntary work

    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.

    2010-09-01

    To relate personal experience and reflections on the tasks and role of a volunteer in an academic palliative care unit into the context of the English publications of 2009. We took a snapshot of the most recent publications as a way of placing the rather unique experiences of this German volunteer in an international context. Five recent studies were found discussing the importance of volunteers in an interdisciplinary context, but mainly focusing on the volunteer's role in the community, interacting with terminally ill patients and their caregivers. Furthermore, aspects of ethical issues, reasons for starting and continuing to volunteer for hospice and the role of male volunteers were evaluated in these studies. The studies feature on the one hand the positive recognition of volunteers, for example, two studies revealed a significant interest by the respondents of having volunteers if they were dying. Also, these articles focused on family carers, who voted for the service of hospice/palliative care volunteers; on the other hand, efforts have to be made to improve the recruitment of volunteers especially if it comes to male support. A further study, reporting on ethical issues, indicates that little is known about these issues when it comes to a volunteer's interaction with a patient in difficult situations, how these are to be managed. These studies give us valuable clues on how and where to make continuous improvements.

  17. CIMS: A Context-Based Intelligent Multimedia System for Ubiquitous Cloud Computing

    2015-06-01

    Full Text Available Mobile users spend a tremendous amount of time surfing multimedia contents over the Internet to pursue their interests. A resource-constrained smart device demands more intensive computing tasks and lessens the battery life. To address the resource limitations (i.e., memory, lower maintenance cost, easier access, computing tasks in mobile devices, mobile cloud computing is needed. Several approaches have been proposed to confront the challenges of mobile cloud computing, but difficulties still remain. However, in the coming years, context collecting, processing, and interchanging the results on a heavy network will cause vast computations and reduce the battery life in mobiles. In this paper, we propose a “context-based intelligent multimedia system” (CIMS for ubiquitous cloud computing. The main goal of this research is to lessen the computing percentage, storage complexities, and battery life for mobile users by using pervasive cloud computing. Moreover, to reduce the computing and storage concerns in mobiles, the cloud server collects several groups of user profiles with similarities by executing K-means clustering on users’ data (context and multimedia contents. The distribution process conveys real-time notifications to smartphone users, according to what is stated in his/her profile. We considered a mobile cloud offloading system, which decides the offloading actions to/from cloud servers. Context-aware decision-making (CAD customizes the mobile device performance with different specifications such as short response time and lesser energy consumption. The analysis says that our CIMS takes advantage of cost-effective features to produce high-quality information for mobile (or smart device users in real time. Moreover, our CIMS lessens the computation and storage complexities for mobile users, as well as cloud servers. Simulation analysis suggests that our approach is more efficient than existing domains.

    Okun, Morris A; Schultz, Amy

    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.

    Volunteers are increasingly being relied upon to provide home-based care for people living with AIDS in South Africa and this presents several unique challenges specific to the HIV/AIDS context in Africa. Yet it is not clear what motivates people to volunteer as home-based caregivers. Drawing on the functional theory on volunteer motivations, this study uses data from qualitative interviews with 57 volunteer caregivers of people living with HIV/AIDS in six semi-rural South African communities to explore volunteer motivations. Findings revealed complex motivations underlying volunteering in AIDS care. Consistent with functional theorizing, most of the volunteers reported having more than one motive for enrolling as volunteers. Of the 11 categories of motivations identified, those relating to altruistic concerns for others and community, employment or career benefits and a desire by the unemployed to avoid idleness were the most frequently mentioned. Volunteers also saw volunteering as an opportunity to learn caring skills or to put their own skills to good use, for personal growth and to attract good things to themselves. A few of the volunteers were heeding a religious call, hoping to gain community recognition, dealing with a devastating experience of AIDS in the family or motivated for social reasons. Care organizations' poor understanding of volunteer motives, a mismatch between organizational goals and volunteer motivations, and inadequate funding meant that volunteers' most pressing motives were not satisfied. This led to discontentment, resentment and attrition among volunteers. The findings have implications for home-based care policies and programmes, suggesting the need to rethink current models using non-stipended volunteers in informal AIDS care. Information about volunteer motivations could help organizations plan recruitment messages, recruit volunteers whose motives match organizational goals and plan how to assist volunteers to satisfy these motives

    In the past years Volunteered Geographic Information (VGI) has emerged as a novel form of user-generated content, which involves active generation of geo-data for example in citizen science projects or during crisis mapping as well as the passive collection of data via the user's location-enabled mobile devices. In addition there are more and more sensors available that detect our environment with ever greater detail and dynamics. These data can be used for a variety of applications, not only for the solution of societal tasks such as in environment, health or transport fields, but also for the development of commercial products and services. The interpretation, visualisation and usage of such multi-source data is challenging because of the large heterogeneity, the differences in quality, the high update frequencies, the varying spatial-temporal resolution, subjective characteristics and low semantic structuring. Therefore the German Research Foundation has launched a priority programme for the next 3-6 years which will support interdisciplinary research projects. This priority programme aims to provide a scientific basis for raising the potential of VGI- and sensor data. Research questions described more in detail in this short paper span from the extraction of spatial information, to the visual analysis and knowledge presentation, taking into account the social context while collecting and using VGI.

    Recently, the LHC@home system has been revived at CERN. It is a volunteer computing system based on BOINC which boosts the available CPU-power in institutional computer centres with the help of individuals that donate the CPU-time of their PCs. Currently two projects are hosted on the system, namely SixTrack and Test4Theory. The first is aimed at performing beam dynamics simulations, while the latter deals with the simulation of high-energy events. In this paper the details of the global system, as well a discussion of the capabilities of each project will be presented.

  5. Motivations of German Hospice Volunteers: How Do They Compare to Nonhospice Volunteers and US Hospice Volunteers?

    We examined reasons of volunteering for hospice and nonhospice organizations in a study with 125 volunteers (22-93 years) from the United States and Germany. Motives of US and German hospice volunteers revealed similarities and few differences. Hospice volunteers are involved because they seek to help others, seek new learning experiences, seek social contacts, or seek personal growth. The US hospice volunteers reported motives related to altruistic concerns, enhancement, and social influence as more influential, while German hospice volunteers rated career expectations as being more important. Comparison of German hospice with nonhospice volunteers revealed stronger differences: German hospice volunteers scored higher on altruistic motives, while German nonhospice volunteers yielded higher scores on self-serving motives. Findings contribute to improved understanding of volunteering motivation and of activating or retaining hospice volunteers. © The Author(s) 2014.

    This article examines the phenomenon of volunteering from a benefit-cost perspective. Both the individual making a decision to volunteer and the organization making a decision to use volunteer labor face benefits and costs of their actions, yet these costs and benefits almost always remain unarticulated, perhaps because the common perception of…

    Distributed volunteer computing can enable researchers and scientist to form large parallel computing environments to utilize the computing power of the millions of computers on the Internet, and use them towards running large scale environmental simulations and models to serve the common good of local communities and the world. Recent developments in web technologies and standards allow client-side scripting languages to run at speeds close to native application, and utilize the power of Graphics Processing Units (GPU). Using a client-side scripting language like JavaScript, we have developed an open distributed computing framework that makes it easy for researchers to write their own hydrologic models, and run them on volunteer computers. Users will easily enable their websites for visitors to volunteer sharing their computer resources to contribute running advanced hydrological models and simulations. Using a web-based system allows users to start volunteering their computational resources within seconds without installing any software. The framework distributes the model simulation to thousands of nodes in small spatial and computational sizes. A relational database system is utilized for managing data connections and queue management for the distributed computing nodes. In this paper, we present a web-based distributed volunteer computing platform to enable large scale hydrological simulations and model runs in an open and integrated environment.

    This paper introduces a framework for inferring human activities in mobile devices by computing spatial contexts, temporal contexts, spatiotemporal contexts, and user contexts. A spatial context is a significant location that is defined as a geofence, which can be a node associated with a circle, or a polygon; a temporal context contains time-related information that can be e.g., a local time tag, a time difference between geographical locations, or a timespan; a spatiotemporal context is defined as a dwelling length at a particular spatial context; and a user context includes user-related information that can be the user's mobility contexts, environmental contexts, psychological contexts or social contexts. Using the measurements of the built-in sensors and radio signals in mobile devices, we can snapshot a contextual tuple for every second including aforementioned contexts. Giving a contextual tuple, the framework evaluates the posteriori probability of each candidate activity in real-time using a Naïve Bayes classifier. A large dataset containing 710,436 contextual tuples has been recorded for one week from an experiment carried out at Texas A&M University Corpus Christi with three participants. The test results demonstrate that the multi-context solution significantly outperforms the spatial-context-only solution. A classification accuracy of 61.7% is achieved for the spatial-context-only solution, while 88.8% is achieved for the multi-context solution.

    Capacity building partnerships between healthcare institutions have the potential to benefit both partners particularly in staff development. Previous research suggests that volunteering can contribute to professional development but there is little evidence on how learning is acquired, the barriers and facilitators to learning in this context or the process of translation of learning to the home environment. Volunteers from a healthcare partnership between the UK and Somaliland reported learning in communication, interdisciplinary working, teaching, management, leadership and service development. This learning came from observing familiar practices in unfamiliar environments; alternative solutions to familiar problems; learning about Somali culture; opportunities to assume higher levels of responsibility and new professional relationships. There was variability in the extent of translation to NHS practice. Time and support available for reflection and mentoring were important facilitators of this process. The professional development outcomes documented in this study came directly from the experience of volunteering. Experiential learning theory suggests that this requires a complex process of critical reflection and new knowledge generation, testing and translation for use in new contexts. This process benefits from identification of learning as an important element of volunteering and support for reflection and the translation translation of learning to UK contexts. We suggest that missed opportunities for volunteer learning will remain until the volunteering process is overtly framed as part of continuing professional development.

In line with predictions, Study 1 revealed that providing non-volunteers with information about organizational support induced anticipated feelings of respect, which subsequently enhanced their attraction to the volunteer organization. However, information about the current success of the volunteer organization did not affect anticipated pride (as among those who seek paid employment) and in fact caused potential volunteers to perceive the organization as being in less need for additional volunteers. Study 2 further showed that information about support from the volunteer organization is a more relevant source of anticipated respect and organizational attraction than support from co-volunteers. Study 3 finally showed that information about task and emotional support for volunteers contributes to anticipated respect and organizational attractiveness and that this increases the actual willingness of non-volunteers to participate in the volunteer organization. Interventions aimed at attracting volunteers and avenues for further research are discussed.

    Volunteer desktop grids are nowadays becoming more and more powerful thanks to improved high end components: multi-core CPUs, larger RAM memories and hard disks, better network connectivity and bandwidth, etc. As a result, desktop grid systems can run more complex experiments or simulations, but some problems remain: the heterogeneity of hardware architectures and software (library dependencies, code length, big repositories, etc.) make it very difficult for researchers and developers to deploy and maintain a software stack for all the available platforms. In this paper, the employment of virtualization is shown to be the key to solve these problems. It provides a homogeneous layer allowing researchers to focus their efforts on running their experiments. Inside virtual custom execution environments, researchers can control and deploy very complex experiments or simulations running on heterogeneous grids of high-end computers. The following work presents the latest results from CERN’s LHC@home Test4Theory p...

    Derks, Daantje; Bos, Arjan E R; von Grumbkow, Jasper

    2008-02-01

    This study investigated the role of emoticons in computer-mediated communication (CMC). The study consisted of an online questionnaire about the social motives for emoticon use and an experimental part in which participants (N = 1,251) had to respond to short Internet chats. In these chats, the interaction partner (friend vs. stranger) and the valence of the context (positive vs. negative) were manipulated. Results showed that emoticons are mostly used to express emotion, to strengthen a message, and to express humor. Furthermore, more emoticons were used in communication with friends than in communication with strangers, and more emoticons were used in a positive context than in a negative context. Participants seem to use emoticons in a way similar to facial behavior in face-to-face communication with respect to social context and interaction partner.

    2016-05-01

    Previous research indicates that volunteer satisfaction and enjoyment do not exert direct effects on the cessation of volunteering by older adults. This study examined whether satisfaction with and enjoyment of volunteering indirectly affect volunteer cessation via hours volunteered. Our sample consisted of participants in the Americans' Changing Lives study (N = 380) who were 65 years old and older and who volunteered at Wave 1. Volunteer satisfaction, volunteer enjoyment, hours volunteered, and several covariates were assessed at Wave 1, and volunteer cessation was assessed 3 years later at Wave 2. Volunteer satisfaction and volunteer enjoyment were positively associated with hours volunteered, and more hours volunteered was associated with decreased likelihood of volunteer cessation. The indirect effects of volunteer satisfaction and volunteer enjoyment on volunteer cessation via hours volunteered were -.023 (p = .059) and -.036 (p = .015), respectively. The dynamics of volunteer cessation are important because a volunteer shortage is forecasted and because the benefits of volunteering may attenuate when volunteering stops. Future research should test the proposed causal sequence using longitudinal data with at least 3 waves. © The Author 2014.

    Full Text Available Canadian- and foreign-born volunteers have contributed to the settlement of newcomers into Canadian society. Despite their important contribution, little has been reported about the experiences and perspectives of these volunteers. Using the information collected from face-to-face interviews with 60 Canadian- and foreign-born volunteers who support newcomers, this article discusses factors that motivate people to volunteer with newcomers. The study results revealed among other findings that (1 to become a volunteer, one not only needs to be motivated but also needs to believe that volunteering will produce the expected positive results and to have confidence in one’s ability to complete the assigned tasks, (2 once people become volunteers, the experience of volunteering tests their perceived self-efficacy and their belief about the effectiveness of their volunteer work. Success or failure in their expectations influences their decision tocontinue or discontinue their volunteer work.

  2. Improving quality of life in ageing populations: what can volunteering do?

    Cattan, Mima; Hogg, Eddy; Hardill, Irene

    2011-12-01

    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.

    Early-phase HIV cure research is conducted against a background of highly effective antiretroviral therapy, and involves risky interventions in individuals who enjoy an almost normal life expectancy. To explore perceptions of three ethical topics in the context of HIV cure research-(a) equipoise, (b) risk-benefit ratios, and (c) "otherwise healthy volunteers"-we conducted 36 in-depth interviews (IDIs) with three groups of purposively selected key informants: clinician-researchers ( n = 11), policy-makers and bioethicists ( n = 13), and people living with HIV (PLWHIV; n = 12). Our analysis revealed variability in perceptions of equipoise. Second, most key informants believed there was no clear measure of risk-benefit ratios in HIV cure research, due in part to the complexity of weighing (sometimes unknown) risks to participants and (sometimes speculative) benefits to science and society. Third, most clinician-researchers and policy-makers/bioethicists viewed potential HIV cure study participants as "otherwise healthy volunteers," but this perception was not shared among PLWHIV in our study.

    2016-01-01

    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 found to have an effect on overall mean well-being generally in life

    Full Text Available The rapid advance in mobile communications has made information and services ubiquitously accessible. Location and context information have become essential for the effectiveness of services in the era of mobility. This paper proposes the concept of geo-context that is defined as an integral synthesis of geographical location, human motion state and mobility context. A geo-context computing solution consists of a positioning engine, a motion state recognition engine, and a context inference component. In the geo-context concept, the human motion states and mobility context are associated with the geographical location where they occur. A hybrid geo-context computing solution is implemented that runs on a smartphone, and it utilizes measurements of multiple sensors and signals of opportunity that are available within a smartphone. Pedestrian location and motion states are estimated jointly under the framework of hidden Markov models, and they are used in a reciprocal manner to improve their estimation performance of one another. It is demonstrated that pedestrian location estimation has better accuracy when its motion state is known, and in turn, the performance of motion state recognition can be improved with increasing reliability when the location is given. The geo-context inference is implemented simply with the expert system principle, and more sophisticated approaches will be developed.

    The aim of this article is to describe the potential with respect to volunteer work among 55 to 70-year-old persons along with a two-dimensional typology (actual volunteer work and intention of volunteering or expanding actual volunteer work) and to identify the influencing factors. Based on the dataset from the transitions and old age potential (TOP) study, a total of 4421 men and women born between 1942 and 1958 were included. A multinomial regression model showed the predictors for group affiliation along with an engagement-related typology (internal, utilized and external volunteer potential as well as definite non-volunteers). More than a half of the persons in the study sample could be classified as internal or external volunteer potential. Volunteers and potential volunteers revealed more similarities regarding resources and social factors than potential volunteers and definite non-volunteers. Potential volunteers were more active in other informal fields of activity (e.g. nursing or child care) than definite non-volunteers. With respect to volunteer work, definite non-volunteers showed various social disadvantages (in particular with respect to education and health) compared to (potential) volunteers. Other informal activities did not seem to be in major conflict with volunteer activities, e.g. nursing or child care, as long as they were carried out with moderate or low intensity.

  12. Volunteering as a predictor of all-cause mortality: what aspects of volunteering really matter?

    2008-10-01

    This study evaluates the predictive effects of different aspects of volunteering (e.g. volunteering status, number of hours, number of years, and type of volunteering activity) on all-cause mortality. A seven-year follow-up dataset of a nationally representative sample of Israelis, 60 years and older was used. As expected, volunteering was associated with a reduced mortality risk even after adjusting for age, gender, education, baseline mental health and physical health, activity level, and social engagement. Those who volunteered for 10 to 14 years had a reduced mortality risk relative to non-volunteers. In addition, those who volunteered privately, not as part of an official organization, also had a reduced mortality risk compared to non-volunteers. The number of hours of volunteering was not a significant predictor of all-cause mortality in the fully adjusted model. In additional sensitivity analyses limited to those who volunteered, none of the various aspects of volunteering was associated with a reduced mortality risk. Results suggest that not all aspects of volunteering have the same predictive value and that the protective effects of length of volunteering time and type of volunteering are particularly important. However, whether or not volunteering is the most consistent predictor of mortality and whether once a person volunteers the various aspects of volunteering are no longer associated with mortality risk.

    CT findings of demented patients with CVD (49 cases) and without CVD (51 cases) were compared with those of healthy age matched volunteers with CVD (29 cases) and without CVD (110 cases). The results were as follows. 1) About 20 % of healthy volunteers had CVD (silent stroke) and these cases should never be regarded as real healthy aged peoples. 2) In aged healthy peoples, size of lateral ventricles, sulci and Sylvian fissure were increased with aging. The degree of PVL and size of third ventricle were not increased with age. 3) Incidence of PVL was closely related with presence of CVD. In demented patients without CVD, however, PVL increased with aging. 4) In dementia the size of lateral ventricle, sulci, Sylvian fissure and third ventricle showed no correlation with aging. In general, enlargement of the lateral ventricle and Sylvian fissure were more prominent in demented peoples without CVD. 5) Atrophy in the medial temporal lobe were observed most frequently in demented peoples without CVD aged 50 to 59 years. In demented patients over 60, no difference was observed in finding of the area between those with and without CVD. (author)

    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.

It is assumed that volunteers will strengthen community health care services more in the future than they do today.Aim: The aim of this study was to elucidate lived experiences of working as a volunteer in an activity center with adapted activities for home-dwelling people with early stage dementia.Methods: Qualitative interviews were implemented in a group of nine female volunteers from an activity center in southern Norway. The interviews were recorded, transcribed verbatim, and analyzed with a descriptive phenomenological method. Results: Volunteering in an activity center for home-dwelling people with early stage dementia was reported to provide experiences of being useful and feeling satisfied with performing a good job. It was an advantage for the volunteers to have had experiences from life in general, but also as a health professional or as being the next of kin of a dementia sufferer. It was important for the volunteers to focus on the dementia sufferer and show caring behavior, and interaction with and the appreciation of the health care professionals were also important. The volunteers were motivated by being able to have influence and participate in the planning of the work, to be a part of the social setting, and to learn. However, for some volunteers it was difficult to adjust to an appropriate role.Conclusion: In order to promote volunteering in a caring context, mutual

    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 motivation. Value-expressive volunteer motivation and religiosity were significant (p motivation and volunteering (p motivation (p > .45). Religiosity may provide the way, and value-expressive volunteer motivation the will, to volunteer.

    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.

  19. Assessing the Role of Technology in Citizen Science: A Volunteer's Perspective

    Wei, J. H.; Force, A.

    2017-12-01

    From a volunteer's perspective, citizen science can provide a direct connection between outdoor enthusiasts and the scientists who study these natural environments. These experiences are both rewarding and engaging, as participants become aware of field sites, the scientific method, and their own environmental impacts. Recent technological advances (i.e. smart phones and mobile applications) have the potential to transform citizen science, specifically as technology can both enable and modernize the networks between a large community of potential volunteers and scientists using these data. By providing volunteers who venture into largely understudied and remote areas with an easy method for data collection and entry, it becomes easier to encourage volunteer engagement in science, while maintaining quality control over the data collection process. Participating in Adventure Scientists' projects demonstrates the application of technology as an effective engagement tool, especially when compared to traditional pen and paper surveys often conducted. Pairing volunteers with simple, familiar technology increases engagement, particularly for volunteers otherwise intimidated by the scientific process. When equipped with useful features, such as GPS functionality, smartphone apps offer a simple and standardized method of data collection and description. Yet a variety of factors can complicate field sampling; final choices are ultimately left to the judgment of the volunteer and perhaps could be guided by use of a phone/app. Importantly, Adventure Scientists conducts follow ups and volunteer surveys, which are critical to the continued evaluation of volunteer experiences and the sampling methods themselves. For future projects, creating a forum in which scientists and volunteers can interact (perhaps also through a phone app) could provide scientific context for volunteers, further investing them in the scientific process and their continued participation.

    The distributed cloud using the CloudScheduler VM provisioning service is one of the longest running systems for HEP workloads. It has run millions of jobs for ATLAS and Belle II over the past few years using private and commercial clouds around the world. Our goal is to scale the distributed cloud to the 10,000-core level, with the ability to run any type of application (low I/O, high I/O and high memory) on any cloud. To achieve this goal, we have been implementing changes that utilize context-aware computing designs that are currently employed in the mobile communication industry. Context-awareness makes use of real-time and archived data to respond to user or system requirements. In our distributed cloud, we have many opportunistic clouds with no local HEP services, software or storage repositories. A context-aware design significantly improves the reliability and performance of our system by locating the nearest location of the required services. We describe how we are collecting and managing contextual information from our workload management systems, the clouds, the virtual machines and our services. This information is used not only to monitor the system but also to carry out automated corrective actions. We are incrementally adding new alerting and response services to our distributed cloud. This will enable us to scale the number of clouds and virtual machines. Further, a context-aware design will enable us to run analysis or high I/O application on opportunistic clouds. We envisage an open-source HTTP data federation (for example, the DynaFed system at CERN) as a service that would provide us access to existing storage elements used by the HEP experiments.

    2011-10-13

    While use of the Internet is increasingly widespread in research, little is known about the role of routine electronic mail (email) correspondence during recruitment and early volunteer-researcher interactions. To gain insight into the standpoint of volunteers we analyzed email communications in an early rheumatoid arthritis qualitative interview study. The objectives of our study were (1) to understand the perspectives and motivations of individuals who volunteered for an interview study about the experiences of early rheumatoid arthritis, and (2) to investigate the role of emails in volunteer-researcher interactions during recruitment. Between December 2007 and December 2008 we recruited 38 individuals with early rheumatoid arthritis through rheumatologist and family physician offices, arthritis Internet sites, and the Arthritis Research Centre of Canada for a (face-to-face) qualitative interview study. Interested individuals were invited to contact us via email or telephone. In this paper, we report on email communications from 12 of 29 volunteers who used email as their primary communication mode. Emails offered insights into the perspective of study volunteers. They provided evidence prospectively about recruitment and informed consent in the context of early rheumatoid arthritis. First, some individuals anticipated that participating would have mutual benefits, for themselves and the research, suggesting a reciprocal quality to volunteering. Second, volunteering for the study was strongly motivated by a need to access health services and was both a help-seeking and self-managing strategy. Third, volunteers expressed ambivalence around participation, such as how far participating would benefit them, versus more general benefits for research. Fourth, practical difficulties of negotiating symptom impact, medical appointments, and research tasks were revealed. We also reflect on how emails documented volunteer-researcher interactions, illustrating typically

    This study examined the moderating effect of gender on the relationship between cognitive social capital and formal volunteering among older adults in urban China. Cognitive social capital refers to individuals' perceptions of their social relationships in local communities. We used quota sampling to recruit 456 older adults aged 60 years and older from 16 communities of Gusu district, Suzhou city, in late 2015. Multiple group analysis was used to examine the proposed model. Gender had a moderating effect on the relationship between cognitive social capital and volunteering. The associations between cognitive social capital and volunteering were higher among older men than older women. The findings highlight the important role of cognitive social capital in influencing formal volunteering among older adults in urban Chinese contexts. The findings are particularly important for enhancing volunteering among older adults across different social and economic backgrounds. Policy and intervention implications are discussed.

    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.

    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). 2007 APA, all rights reserved

Method: Phenomenological study based on the assumptions related to the analysis of the stated phenomenon's structure, with eleven volunteers to be interviewed upon a guiding question: "What does it feel like to be a volunteer in a toy library used by children with cancer?". Results: From the volunteer's answers, three theme categories arose: self-oriented relations, group-oriented relations and world-oriented relations. Conclusion and implications for practice: Being a volunteer embraces diverse relationships that contribute to the self-knowledge of the individual, making it possible to review concepts, beliefs, values, according to the new times in which we live There is a need for volunteer empowerment for work as well as mental health care. Nurses play a fundamental role in this context.

  8. Motives for Volunteering: Categorization of Volunteers' Motivations Using Open-ended Questions

    Directory of Open Access Journals (Sweden)

    Fernando Chacón

    2010-12-01

    Full Text Available Most studies of volunteers’ motivations use standardized questionnaires with one of the most commonly-used being the Volunteer Function Inventory. Open-ended questions about what drives individuals to be volunteers are seldom used. We hypothesize that questionnaires tend to overestimate the number of motivations and to underestimate their variety. Therefore, in this paper we analyze the answers of 1515 volunteers to an open-ended question and categorize these answers. Results show that volunteers give an average of 2 motivations, fewer than the questionnaires, and that the Value motivation is the most frequently mentioned and the most important for volunteers. In addition, this motivation coexists with other motivations, which are lacking in the standard questionnaires, such as Organizational Commitment, Personal Development, Religiosity, Social Change or Interest in the Activity.

  9. Learning in Later Life: Benefits and Challenges for Volunteers and Agencies.

    2016-01-01

    Older adults in most societies are keen volunteers in a myriad of contexts for the betterment of individuals and for the agencies in which they volunteer. This article discusses how volunteerism among older adults may enhance their learning and the kinds of benefits and challenges they encounter in their work for employing authorities. It also considers how agencies can be better attuned to the lifelong learning aspirations of older volunteers. Research related to older adults, lifelong learning and the character of volunteerism is reviewed with examples provided from New Zealand and Australia of older adults' participation in volunteerism and consequential impact. While volunteerism is normally viewed as a "win-win" situation for the volunteers and the organisations in which knowledge is further developed for varied purposes (economic sufficiency; personal development; active citizenship; social inclusion), there are nevertheless challenges for both parties. The article explores salient factors which function as enhancers or limitations for older volunteers in their work and learning. It is important that the motives of volunteers for participation are fully transparent and understood by the older adults themselves and by the relevant agencies. Organisations can provide considerable opportunities for older people to engage in continuing learning/ education but they need to be aware of effective recruitment and retention strategies; older people can provide a much needed labour resource where their previous life experiences can be drawn upon and they should be fully cognisant of the organisation's mission and how they can help to enhance it.

    Many young people look forward to volunteering abroad and overlook the ample volunteer opportunities at home. There are several advantages to volunteering at home: you help people in your own community; you can make a long-term commitment; and you have continuity of care for your patients. There are >1200 free clinics in the United States whose main goal is to provide care to the indigent population. These free clinics are always looking for volunteers with specialized medical training. This article reviews the medically related and unrelated volunteer opportunities available in the United States. Volunteering at home is a worthwhile experience, and I encourage the otolaryngology community to explore these opportunities. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    2017-01-01

    Volunteering in the hospice movement has had a profound impact on generating awareness of hospice work and palliative care in the context of supporting dying persons and their relatives as well as on integrating respective services in the existing health care system. This paper focuses on two specific questions: First, it asks how society is changing with respect to dealing with dying and death, and more precisely with dying persons, which is recognizable by the integration of hospice work and palliative care in the healthcare system and related to the relevance of volunteering in the sense of a citizens' movement. Second, this paper asks what the specific roles of volunteers are as well as the possibilities and limits of voluntary practice in end-of-life care and accompaniment. To answer these questions, the pivotal objectives of the hospice movement - the transformation of the social awareness regarding dying and death, as well as the reorganization of "institutions of dying" - will first be outlined by reference to the concept of "good dying", a specific hospice attitude together with hospice culture and palliative competence. In a second step, the relevance of volunteering and the specific role of volunteers in the actual practice of hospice work and palliative care will be outlined alongside current indicators and recognizable alteration tendencies, before concluding with a discussion of the perspectives of hospices as a citizens' movement.

  14. Motivations and Benefits of Student Volunteering: Comparing Regular, Occasional, and Non-Volunteers in Five Countries

    2010-01-01

    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.

    Samson, André; Lavigne, René M; MacPherson, Paul

    2009-11-01

    With the decline in the morbidity and mortality associated with HIV infection, the majority of people living with HIV (PWHIV) experience a higher quality of life and longer life expectancy. Since this diagnosis no longer prevents an active lifestyle, many PWHIV are re-integrating into the workplace or are contemplating this possibility. Despite the multiple advantages associated with a return to work, research has identified barriers related to work and HIV infection. These barriers could prevent an important minority of PWHIV who wish to return to work from re-integrating into this environment. In this context, volunteering could be an alternate way to regain an active lifestyle. This research found that volunteer work allowed participants to enrich their social lives, to regain a sense of psychological well-being, and to apply their abilities to the benefit of others. However, participants are restricted by their preference to volunteer for HIV-related organizations in order to avoid social stigma and rejection.

    2009-12-01

    We summarize radio and optical SETI programs based at the University of California, Berkeley. The ongoing SERENDIP V sky survey searches for radio signals at the 300 meter Arecibo Observatory. The currently installed configuration supports 128 million channels over a 200 MHz bandwidth with 1.6 Hz spectral resolution. Frequency stepping allows the spectrometer to cover the full 300 MHz band of the Arecibo L-band receivers. The final configuration will allow data from all 14 receivers in the Arecibo L-band Focal Array to be monitored simultaneously with over 1.8 billion simultaneous channels. SETI@home uses desktop computers volunteers to analyze over 100 TB of at taken at Arecibo. Over 5 million volunteers have run SETI@home during its 10 year history. The SETI@home sky survey is 10 times more sensitive than SERENDIP V but it covers only a 2.5 MHz band, centered on 1420 MHz. SETI@home searches a much wider parameter space, including 14 octaves of signal bandwidth and 15 octaves of pulse period with Doppler drift corrections from -100 Hz/s to +100 Hz/s. The ASTROPULSE project is the first SETI search for μs time scale pulses in the radio spectrum. Because short pulses are dispersed by the interstellar medium, and amount of dispersion is unknown, ASTROPULSE must search through 30,000 possible dispersions. Substantial computing power is required to conduct this search, so the project will use volunteers and their personal computers to carry out the computation (using distributed computing similar to SETI@home). The SEVENDIP optical pulse search looks for ns time scale pulses at visible wavelengths. It utilizes an automated 30 inch telescope, three ultra fast photo multiplier tubes and a coincidence detector. The target list includes F,G,K and M stars, globular cluster and galaxies.

    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.

    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. Copyright © 2011 Mosby, Inc. All rights reserved.

    2014-12-01

    Full Text Available The European Voluntary Service of the European Union is thought to play a key role in promoting and encouraging volunteering among young people. Integrating the social work of EVS volunteers into activities through sport organizations is believed to help develop the perception of volunteering as an element of social commitment. The aim of this study is to therefore examine a case of youth volunteering practice in an EVS project in Turkey within the context of the benefits of volunteering. Data was collected using various tools. These included semi-structured interviews, participant observation (non-structured, and document analyses. Content analyses were applied to the interview data. The study established that the EVS is a beneficial channel for youth volunteering and provides benefits for each of the parties: the volunteers, the organization, and the sport participants.

    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.

    2014-01-01

    This paper investigates the influence of presenting volunteered and professionally created geographic information to 101 wheelchair users through an interactive website that included information collected by wheelchair-using volunteers. The aim of this experiment was to understand the influence that (1) knowing a map-based website contains volunteered information and (2) actually including volunteered information within an online interactive map (a mashup) have on the perceived trust of the user, described in terms of quality and authority. Analysis using Kruskal-Wallis showed that judgements of currency were influenced by including geo-information from untrained volunteers (volunteered geographic information) within the mashup, but not influenced by the participant being told that the online map contained volunteered information. The participants appeared to make judgements based on what information they saw, rather than what they were told about the source of the information. Since 2004, information services have combined crowdsourced (volunteered) alongside professional information within online interactive maps. An online experiment presented both of these information types to wheelchair users within a travel context. Including volunteered information was shown to increase the perceptions of how up-to-date the maps were.

    Saho, Tatsunori; Onishi, Hideo

    2016-07-01

    In this study, we evaluated the hemodynamics of carotid artery bifurcation with various geometries using simulated and volunteer models based on magnetic resonance imaging (MRI). Computational fluid dynamics (CFD) was analyzed by use of OpenFOAM. The velocity distribution, streamline, and wall shear stress (WSS) were evaluated in a simulated model with known bifurcation angles (30°, 40°, 50°, 60°, derived from patients' data) and in three-dimensional (3D) healthy volunteer models. Separated flow was observed at the outer side of the bifurcation, and large bifurcation models represented upstream transfer of the point. Local WSS values at the outer bifurcation [both simulated (100 Pa). The bifurcation angle had a significant negative correlation with the WSS value (p<0.05). The results of this study show that the carotid artery bifurcation angle is related to the WSS value. This suggests that hemodynamic stress can be estimated based on the carotid artery geometry. The construction of a clinical database for estimation of developing atherosclerosis is warranted.

    1993-01-01

    While the sinking of the Tenyo Maru and resultant oil spill off Washington's Olympic Peninsula in July 1991 was tragic, it fostered the birth of a cooperative effort by federal and state agencies to train volunteer responders prior to another oil spill. This effort, under the auspices of an Oregon nonprofit group known as SOLV (Stop Oregon Littering and Vandalism), is known as the SOS (SOLV Oil Spill) Steering committee. The purpose of the group is to train volunteer responders to aid federal, state, and local agencies in future oil spill cleanup activities. For the first time in the nation, governmental agencies have joined with corporations and environmental organizations in coordinating educational programs involving citizens in oil spill remediation efforts before the advent of a major spill that could affect coastal areas or inland waterways. Free classes meeting federal and state hazardous waste training criteria are offered quarterly to citizens interested in either volunteer wildlife rehabilitation or beach cleanup. The four-hour course was developed by the US Coast Guard, Oregon State Department of Environmental Quality, and Oregon OSHA. Topics covered include agency responsibilities, site safety plans, general safety, toxicology, material safety data sheets, personal protective equipment, decontamination, heat stress, helicopter safety, and wildlife safety. In addition to course materials, participants receive a certificate and identification card verifying their training. A 1-800 number, computer data base, and newsletter are used to maintain contact with graduates. So far more than 600 volunteers have been trained and are ready to assist should the need arise

    2013-01-01

    The shift from cookbook to authentic research-based lab courses in undergraduate biology necessitates the need for evaluation and assessment of these novel courses. Although the biology education community has made progress in this area, it is important that we interpret the effectiveness of these courses with caution and remain mindful of inherent limitations to our study designs that may impact internal and external validity. The specific context of a research study can have a dramatic impact on the conclusions. We present a case study of our own three-year investigation of the impact of a research-based introductory lab course, highlighting how volunteer students, a lack of a comparison group, and small sample sizes can be limitations of a study design that can affect the interpretation of the effectiveness of a course.

Rates of volunteering do not decline significantly until the middle of the 7th decade, and older volunteers commit more hours than younger volunteers. Older adults with more human and social capital tend to volunteer, and there is good evidence of a reciprocal relationship between volunteering and well-being. Program and policy developments in the field are outstripping production of knowledge to support evidence-based practices. Research on the dynamics of volunteering over the life course as well as the patterns of activities that co-occur with volunteering is needed to guide program development. Research methods and findings from transdisciplinary work on the mechanisms through which psychosocial conditions affect health must be extended to the study of the effects of volunteering on older adults. Finally, we need to engage in more applied social science aimed at improving volunteer management, especially recruitment and retention of older volunteers.

    Full Text Available Volunteerism as an activity in the context of non profit organizations aknowledged an increasing growth in Romania after the fall of comunism. Research in the nonprofit field is clustered around the identification ofinfluencial factors regarding volunteer involvement. Interest in academic research regarding non profit, third sector and non profit marketing gainedmore popularity in the last two decades. Theories of marketingapplicable in nonprofit sector are disscused, being adopted theorethical constructs from either sciences alsoas sociology, psychology, anthropology and organizational behavior schiences. General accepted conceptual and empirical constructs are not yet developed, which leads to the fact that study on influencial factors on volunteerism stillneeds to be developed and tested. The maininfluencial factors identified in the literature review cluster around personal, situational and organizational. Personal factors analysed were the socio-demographic, motivations, situational factors were cost and time oportunity, availability, experience in the field. On theother side organizational factors identified were charachteristics of the job, internal marketing and relationship with clients. Identified factors have influence on volunteer satisfaction regarding the activity in the organization and organizational commitement, increasing the retention of volunteers

  18. Environmental volunteer well-being: Managers’ perception and actual well-being of volunteers [version 1; referees: 2 approved

    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

    In patients with schizophrenia, deficient generation of mismatch negativity (MMN)-an event-related potential (ERP) indexing auditory sensory ("echoic") memory-and a selective increase of "context dependent" ("BX") errors in the "A-X" version of the Continuous Performance Test (AX-CPT) indicate an impaired ability to form and use transient memory traces. Animal and human studies implicate deficient N-methyl-D-aspartate receptor (NMDAR) functioning in such abnormalities. In this study, effects of the NMDAR antagonists ketamine on MMN generation and AX-CPT performance were investigated in healthy volunteers to test the hypothesis that NMDARs are critically involved in human MMN generation, and to assess the nature of ketamine-induced deficits in AX-CPT performance. In a single-blind placebo-controlled study, 20 healthy volunteers underwent an infusion with subanesthetic doses of ketamine. The MMN-to-pitch and MMN-to-duration deviants were obtained while subjects performed an AX-CPT. Ketamine significantly decreased the peak amplitudes of the MMN-to-pitch and MMN-to-duration deviants by 27% and 21%, respectively. It induced performance deficits in the AX-CPT characterized by decreased hit rates and specific increases of errors (BX errors), reflecting a failure to form and use transient memory traces of task relevant information. The NMDARs are critically involved in human MMN generation. Deficient MMN in schizophrenia thus suggests deficits in NMDAR-related neurotransmission. N-methyl-D-aspartate receptor dysfunction may also contribute to the impairment of patients with schizophrenia in forming and using transient memory traces in more complex tasks, such as the AX-CPT. Thus, NMDAR-related dysfunction may underlie deficits in transient memory at different levels of information processing in schizophrenia. Arch Gen Psychiatry. 2000;57:1139-1147.

    Full Text Available The shift from cookbook to authentic research-based lab courses in undergraduate biology necessitates the need for evaluation and assessment of these novel courses. Although the biology education community has made progress in this area, it is important that we interpret the effectiveness of these courses with caution and remain mindful of inherent limitations to our study designs that may impact internal and external validity. The specific context of a research study can have a dramatic impact on the conclusions. We present a case study of our own three-year investigation of the impact of a research-based introductory lab course, highlighting how volunteer students, a lack of a comparison group, and small sample sizes can be limitations of a study design that can affect the interpretation of the effectiveness of a course.

    Canuck Place Children's Hospice (CPCH) is regarded as one of the leading pediatric palliative care systems in the world. Since 1995, it has been providing hospice care free of charge to children and their families living with life-threatening conditions. The pediatric palliative hospice is a relatively new practice in health care, in comparison to the longstanding adult model. As a result, development and implementation of volunteer programs in pediatric hospices is not currently represented in literature. With over 300 volunteers at present, CPCH has built a successful program that can serve as a model in pediatric volunteer services. To present the unique volunteer roles and experience at CPCH, and share ways volunteers work to support the efforts of the clinical team. Strategies to address current challenges in the volunteer program are also addressed. Descriptive design. A current CPCH volunteer discusses the volunteer program. Interviews were conducted with the founding volunteer director of CPCH and current volunteers. The volunteer program at CPCH fully embraces the life of each child and family. Volunteer selection is the groundwork for ensuring a cohesive work force, while training equips volunteers with the knowledge to carry out their role with confidence. Areas of improvement that have been recognized include offering effective feedback to volunteers and delivering adequate level of training for non-direct care roles. The talents of volunteers at CPCH are diverse, and CPCH aims to recognize and thank volunteers for their continuous contributions.

  5. The stresses of hospice volunteer work.

    The purpose of this phenomenological study was to explore the interpretation of stress, the appraisal of the stressors, as well as the top stressors experienced by hospice volunteers. Individual semistructured interviews were conducted with 15 hospice volunteers. The interviews were digitally recorded, transcribed, and analyzed, using qualitative research methods. Although the results indicated that the hospice volunteers did not perceive their work as stressful, 2 main themes regarding challenging experiences did emerge. Hospice-related issues and personal issues were of concern to the volunteers. In addition, the timing of the stressors revealed that the most stress was felt at the beginning of their volunteer services, which has implications for hospice volunteer coordinators as they support their volunteers in the field.

  6. The female community health volunteer programme in Nepal: decision makers' perceptions of volunteerism, payment and other incentives.

    The Female Community Health Volunteer (FCHV) Programme in Nepal has existed since the late 1980s and includes almost 50,000 volunteers. Although volunteer programmes are widely thought to be characterised by high attrition levels, the FCHV Programme loses fewer than 5% of its volunteers annually. The degree to which decision makers understand community health worker motivations and match these with appropriate incentives is likely to influence programme sustainability. The purpose of this study was to explore the views of stakeholders who have participated in the design and implementation of the Female Community Health Volunteer regarding Volunteer motivation and appropriate incentives, and to compare these views with the views and expectations of Volunteers. Semi-structured interviews were carried out in 2009 with 19 purposively selected non-Volunteer stakeholders, including policy makers and programme managers. Results were compared with data from previous studies of Female Community Health Volunteers and from interviews with four Volunteers and two Volunteer activists. Stakeholders saw Volunteers as motivated primarily by social respect, religious and moral duty. The freedom to deliver services at their leisure was seen as central to the volunteer concept. While stakeholders also saw the need for extrinsic incentives such as micro-credit, regular wages were regarded not only as financially unfeasible, but as a potential threat to the Volunteers' social respect, and thereby to their motivation. These views were reflected in interviews with and previous studies of Female Community Health Volunteers, and appear to be influenced by a tradition of volunteering as moral behaviour, a lack of respect for paid government workers, and the Programme's community embeddedness. Our study suggests that it may not be useful to promote a generic range of incentives, such as wages, to improve community health worker programme sustainability. Instead, programmes should ensure that

    2009-09-01

    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.

    Three standard psychometric tests were administered to parents who volunteered their children for a randomised, double-blind placebo-controlled trial of a new asthma drug and to a control group of parents whose children were eligible for the trial but had declined the invitation. The trial took place at a children's hospital in Australia. The subjects comprised 68 parents who had volunteered their children and 42 who had not, a participation rate of 94 per cent and 70 per cent, respectively. The responses of these parents to the Gordon Survey of Interpersonal Values Questionnaire, the Coopersmith Self-Esteem Inventory and the Cattell Sixteen Personality Factor Questionnaire were analysed by computer. There was a marked difference between the psychological profiles of the two groups of parents. Volunteering parents put more value on benevolence while non-volunteering parents were more concerned with power and prestige. The self-esteem of volunteering parents was much lower than that of non-volunteering parents. Finally, volunteering parents were more introverted, exhibited greater anxiety and low supergo, while non-volunteering parents appeared to have greater social confidence and emotional stability. Since an individual's values, self-esteem and personality may be important antecedents of behaviour, these findings suggest that parents who volunteer their children for clinical research are not only socially disadvantaged and emotionally vulnerable, but may also be psychologically predisposed to volunteering. Furthermore, these findings provide evidence for the existence of a psychosocial 'filter' effect of the informed consent procedure, which may be discouraging the better educated, more privileged and psychologically resilient members of society from participation as research subjects.

    2017-03-01

    This study evaluated the successful aging model by assessing the impact of two forms of productive engagement-working and volunteering-as potential interventions in the process of disablement. The Health and Retirement Study was used to (a) estimate two-stage selection equations of (i) currently working part time and full time and (ii) currently volunteering less than 100 hours and volunteering 100 hours or more per year (net of chronic health problems) and (b) assess whether, net of selection, working, and volunteering moderate the association between chronic conditions and subsequent functional limitations. Chronic conditions were associated with elevated levels of subsequent functional limitations, whereas both working and volunteering were associated with lower levels of subsequent functional limitations. Moreover, workers and volunteers of less than 100 hours per year experienced a reduction in the association of chronic conditions on subsequent functional limitations. This research highlights the role of productive engagement as a key element in successful aging. Not only do work and volunteering have direct associations with health outcomes themselves, but they also act as potential interventions in the process of disablement by attenuating the way in which chronic conditions are translated into subsequent functional limitations. This suggests that (a) future research should apply successful aging models to health processes as well as health outcomes and (b) policy makers should support social institutions that foster late-life productive engagement. © The Author 2016.

    2017-11-06

    Volunteered geographic information (VGI) has strong potential to be increasingly valuable to scientists in collaboration with non-scientists. The abundance of mobile phones and other wireless forms of communication open up significant opportunities for the public to get involved in scientific research. As these devices and activities become more abundant, questions of uncertainty and error in volunteer data are emerging as critical components for using volunteer-sourced spatial data. Here we present a methodology for using VGI and assessing its sensitivity to three types of error. More specifically, this study evaluates the reliability of data from volunteers based on their historical patterns. The specific context is a case study in surveillance of tsetse flies, a health concern for being the primary vector of African Trypanosomiasis. Reliability, as measured by a reputation score, determines the threshold for accepting the volunteered data for inclusion in a tsetse presence/absence model. Higher reputation scores are successful in identifying areas of higher modeled tsetse prevalence. A dynamic threshold is needed but the quality of VGI will improve as more data are collected and the errors in identifying reliable participants will decrease. This system allows for two-way communication between researchers and the public, and a way to evaluate the reliability of VGI. Boosting the public's ability to participate in such work can improve disease surveillance and promote citizen science. In the absence of active surveillance, VGI can provide valuable spatial information given that the data are reliable.

    2015-01-01

    This study examined the ways in which individuals over 50 years old solved problems while volunteering in intensive humanitarian and disaster relief service. Thirty-seven men and women in the sample were sponsored by three religious organizations well known for providing humanitarian and disaster relief service. Semistructured interviews yielded data that were analyzed qualitatively, using McCracken's five-step process for analysis. We found that volunteers used three different abilities to solve problems: drawing upon experience to create strategies, maintaining emotional stability in the midst of trying circumstances, and applying strategies in a context-sensitive manner. These findings illustrate that these factors, which are comparable to those used in solving everyday problems, are unique in the way they are applied to intensive volunteering. The volunteers' sharing of knowledge, experience, and support with each other were also noticeable in their accounts of their service. This sharing contributed strongly to their sense of emotional stability and effectiveness in solving problems. © The Author(s) 2015.

  5. The Politicized Motivations of Volunteers in the Refugee Crisis: Intergroup Helping as the Means to Achieve Social Change

    Directory of Open Access Journals (Sweden)

    Anna Kende

    2017-05-01

    Full Text Available The refugee crisis in the summer of 2015 mobilized thousands of volunteers in Hungary to help refugees on their journey through Europe despite the government’s hostile stance. We conducted a survey (N = 1459 among people who were active in supporting refugees and providing services to them to test the hypothesis of whether volunteers in the context of this humanitarian crisis had social change motivations similar to those engaged in direct political activism. Hierarchical regression analysis and mediation analysis revealed the importance of opinion-based identity and moral convictions as predictors of volunteerism, while efficacy beliefs and anger only predicted political activism. Our findings suggest that volunteers engaged in helping refugees based on motivations previously described as drivers of mobilization for political activism, but chose volunteerism to alleviate the problems embedded in the intergroup situation. Although the context of the refugee crisis in Hungary may have been somewhat unique, these findings have implications for other asymmetrical politicized intergroup relations in which advantaged group members can choose to offer humanitarian aid, engage in political actions to change the situation, or do both.

  6. Vocational guidance in social volunteering

    Directory of Open Access Journals (Sweden)

    Nikolay S. Pryazhnikov

    2017-03-01

    Full Text Available The paper discusses the possibilities and limitations of vocational guidance in the social volunteering system. The essence of volunteer work is closely related with assistance to desperate people in searching for the meaning of living, often coinciding with labour activity that are deemed in terms of “the main matter of life” and “the leading activity”. For adolescents, it is the choice of career, and for adults, it is the work proper (i.e. an essential condition for personal self-realization. The problem of “forced volunteering” for experts in vocational guidance also means that they often have to work voluntarily and unselfishly outside the official guidelines. To clarify the terms «volunteer» and «a person in desperate need of help» the study used the method of analyzing the documents, e.g. the Regulations on Social Volunteering, the generalization of psychological sources, the initial survey of university students as active supporters of the volunteer movement, On the essence of volunteering and the place of career guidance in selfless social work. Vocational guidance is not excluded from the general system of volunteerism, but has an insufficiently defined status and low popularity among participants in social volunteering. Also, the problem of «forced volunteering» of experts in career counseling, which often requires voluntary and unselfish performance of quality work outside the framework of official instructions, is also indicated. Simultaneously, positive aspects of such disinterested career initiatives are noted, in particular, less control by the official inspectors (or customers and, accordingly, greater freedom of creativity than when someone else does the work.

    2014-10-14

    This thesis is dedicated to the evaluation of environmental policies in the context of climate change. Its objectives are twofold. Its first part is devoted to the development of potent instruments for quantitative impact analysis of environmental policy. In this context, the main contributions include the development of a new computable general equilibrium (CGE) model which makes use of the new comprehensive and coherent World Input-Output Dataset (WIOD) and which features a detailed representation of bilateral and bisectoral trade flows. Moreover it features an investigation of input substitutability to provide modellers with adequate estimates for key elasticities as well as a discussion and amelioration of the standard base year calibration procedure of most CGE models. Building on these tools, the second part applies the improved modelling framework and studies the economic implications of environmental policy. This includes an analysis of so called rebound effects, which are triggered by energy efficiency improvements and reduce their net benefit, an investigation of how firms restructure their production processes in the presence of carbon pricing mechanisms, and an analysis of a regional maritime emission trading scheme as one of the possible options to reduce emissions of international shipping in the EU context.

    2010-03-01

    Although the role of volunteers is at the heart of hospice care, little is known about hospice volunteer training and volunteer activity. A survey was used to assess current training programs for hospice volunteers. Hospices were invited to participate in the study from a link on the website for the Hospice Volunteer Association and Hospice Educators Affirming Life Project. Survey results revealed that the majority of volunteer work is in patient care, with most hospice agencies requiring a minimum 12-month volunteer commitment and an average 4-hour volunteer shift per week. Volunteer training is separate from staff training, is provided by paid agency staff, and costs approximately $14,303 per year. Communication and family support are considered important curriculum topics. Revisions to current volunteer training curriculum and format are suggested.

    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

    This study tested a theoretical model of volunteering benefits and examined the mechanism through which volunteering benefits older adults. This is a 2-wave study of 253 older adult volunteers serving in 10 volunteer programs. Older volunteers completed the mailed surveys in 2005 and 2006. Structural equation modeling was used to define the latent variables and to test direct and indirect relationships among organizational support, socioemotional benefits, and self-reported health. Organizational support (measured by choice of volunteer activity, training, and ongoing support) had significant direct associations with 2 latent factors of socioemotional benefits, that is, perceived contribution and personal benefits. Perceived contribution was significantly related to mental health. Additionally, older volunteers with lower socioeconomic status (SES) committed more hours and perceived more personal benefits than higher SES peers. These findings suggest that volunteer programs can provide various organizational supports to older volunteers, especially to low-SES volunteers, in order to promote the socioemotional and health benefits of volunteering to older adults. Psychological well-being of older adults can be improved through engagement in meaningful volunteer activities and contribution to others.

    2012-08-01

    We surveyed volunteers from 8 hospices in the Delaware Valley regarding training, perceived needs, and role satisfaction. Results were consistent with previous studies: satisfaction with preservice training and with volunteering was very high; respondents reported feeling very prepared and confident about doing hospice work as a result of their volunteer training. In addition, longer volunteer preservice training was associated with higher levels of overall satisfaction with training; levels of volunteer satisfaction and fulfillment tended to be lower during the first year of volunteering; and participation in volunteer support teams was associated with finding volunteer work rewarding and with feeling a part of the hospice team. Implications for preservice training and ongoing support and education of 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.

    2017-03-01

    Volunteering is beneficial not only for individuals' well-being but also for society's well-being; yet only a fraction of U.S. citizens regularly engage in volunteer activities. This study examined how underlying motivations are associated with interest in volunteering for individuals in three major life phases: early, middle, and later adulthood. Data were collected from 1,046 adults who volunteered through nonprofit organizations in Nevada (USA). Exploratory factor analysis revealed that community service, career advancement, and well-being were common underlying motivations for individuals across life stages. However, generativity among the later adulthood group, and social networking among the early and middle adulthood groups were unique motivations for volunteering. Regression analysis showed that the community service motivation was significantly associated with individuals' interest in volunteering among all life stages. Simultaneously, generativity for the later adulthood group, and career advancement for the early adulthood group were unique motivations linked to their actual interest in volunteering.

  13. Pulsar discoveries by volunteer distributed computing and the strongest continuous gravitational wave signal

    Knispel, Benjamin

    2011-07-01

    Neutron stars are the endpoints of stellar evolution and one of the most compact forms of matter in the universe. They can be observed as radio pulsars and are promising sources for the emission of continuous gravitational waves. Discovering new radio pulsars in tight binary orbits offers the opportunity to conduct very high precision tests of General Relativity and to further our understanding of neutron star structure and matter at super-nuclear densities. The direct detection of gravitational waves would validate Einstein's theory of Relativity and open a new window to the universe by offering a novel astronomical tool. This thesis addresses both of these scientific fields: the first fully coherent search for radio pulsars in tight, circular orbits has been planned, set up and conducted in the course of this thesis. Two unusual radio pulsars, one of them in a binary system, have been discovered. The other half of this thesis is concerned with the simulation of the Galactic neutron star population to predict their emission of continuous gravitational waves. First realistic statistical upper limits on the strongest continuous gravitational-wave signal and detection predictions for realistic all-sky blind searches have been obtained. The data from a large-scale pulsar survey with the 305-m Arecibo radio telescope were searched for signals from radio pulsars in binary orbits. The massive amount of computational work was done on hundreds of thousands of computers volunteered by members of the general public through the distributed computing project Einstein@Home. The newly developed analysis pipeline searched for pulsar spin frequencies below 250 Hz and for orbital periods as short as 11 min. The structure of the search pipeline consisting of data preparation, data analysis, result post-processing, and set-up of the pipeline components is presented in detail. The first radio pulsar, discovered with this search, PSR J2007+2722, is an isolated radio pulsar, likely from

    A variety of organizations redistribute surplus food to low-income populations through food rescue nutrition. Why volunteers participate in these charitable organizations is unclear. The aim of this study is to document the participation and motivations of volunteers who are involved specifically in food rescue nutrition. A cross-sectional study was conducted in two phases. In phase 1, a new instrument, Motivations to Volunteer Scale, was developed and validated in 40 participants (aged ≥18 years). In phase 2, the new scale and a demographics questionnaire were administered to 300 participants who were volunteering in food pantries and churches. The pilot study showed that Motivations to Volunteer Scale exhibited an internal consistency of Cronbach's α of 0.73 (P  0.05). The scale was validated also by comparison to the Volunteer Function Inventory (r = 0.86, P social life, and altruism. The mean motivation score of the 300 volunteers was 9.15 ± 0.17. Greater motivations were observed among participants who were aged >45 years, women, Hispanics, college/university graduates, physically inactive, non-smokers, and had an income ≥ $48,000. The Motivations to Volunteer Scale is a valid tool to assess why individuals volunteer in food rescue nutrition. The extent of motivations of participants was relatively high, and the primary reason for volunteering was altruism. Health professionals should be encouraged to participate in food redistribution.

    The volunteer computing project ATLAS@Home has been providing a stable computing resource for the ATLAS experiment since 2013. It has recently undergone some significant developments and as a result has become one of the largest resources contributing to ATLAS computing, by expanding its scope beyond traditional volunteers and into exploitation of idle computing power in ATLAS data centres. Removing the need for virtualization on Linux and instead using container technology has made the entry barrier significantly lower data centre participation and in this paper, we describe the implementation and results of this change. We also present other recent changes and improvements in the project. In early 2017 the ATLAS@Home project was merged into a combined LHC@Home platform, providing a unified gateway to all CERN-related volunteer computing projects. The ATLAS Event Service shifts data processing from file-level to event-level and we describe how ATLAS@Home was incorporated into this new paradigm. The finishing...

    2012-12-01

    Since 1999, the NASA/JPL Solar System Ambassadors (SSA) and Solar System Educators (SSEP) programs have used specially-trained volunteers to expand education and public outreach beyond the immediate NASA center regions. Integrating nationwide volunteers in these highly effective programs has helped optimize agency funding set aside for education. Since these volunteers were trained by NASA scientists and engineers, they acted as "stand-ins" for the mission team members in communities across the country. Through the efforts of these enthusiastic volunteers, students gained an increased awareness of NASA's space exploration missions through Solar System Ambassador classroom visits, and teachers across the country became familiarized with NASA's STEM (Science, Technology, Engineering and Mathematics) educational materials through Solar System Educator workshops; however the scientist was still distant. In 2003, NASA started the Digital Learning Network (DLN) to bring scientists into the classroom via videoconferencing. The first equipment was expensive and only schools that could afford the expenditure were able to benefit; however, recent advancements in software allow classrooms to connect to the DLN via personal computers and an internet connection. Through collaboration with the DLN at NASA's Jet Propulsion Laboratory and the Goddard Spaceflight Center, Solar System Ambassadors and Solar System Educators in remote parts of the country are able to bring scientists into their classroom visits or workshops as guest speakers. The goals of this collaboration are to provide special elements to the volunteers' event, allow scientists opportunities for education involvement with minimal effort, acquaint teachers with DLN services and enrich student's classroom learning experience.;

    Volunteering has been advocated by the United Nations, and American and European governments as a way to engage people in their local communities and improve social capital, with the potential for public health benefits such as improving wellbeing and decreasing health inequalities. Furthermore, the US Corporation for National and Community Service Strategic Plan for 2011-2015 focused on increasing the impact of national service on community needs, supporting volunteers' wellbeing, and prioritising recruitment and engagement of underrepresented populations. The aims of this review were to examine the effect of formal volunteering on volunteers' physical and mental health and survival, and to explore the influence of volunteering type and intensity on health outcomes. Experimental and cohort studies comparing the physical and mental health outcomes and mortality of a volunteering group to a non-volunteering group were identified from twelve electronic databases (Cochrane Library, Medline, Embase, PsychINFO, CINAHL, ERIC, HMIC, SSCI, ASSIA, Social Care Online, Social Policy and Practice) and citation tracking in January 2013. No language, country or date restrictions were applied. Data synthesis was based on vote counting and random effects meta-analysis of mortality risk ratios. Forty papers were selected: five randomised controlled trials (RCTs, seven papers); four non-RCTs; and 17 cohort studies (29 papers). Cohort studies showed volunteering had favourable effects on depression, life satisfaction, wellbeing but not on physical health. These findings were not confirmed by experimental studies. Meta-analysis of five cohort studies found volunteers to be at lower risk of mortality (risk ratio: 0.78; 95% CI: 0.66, 0.90). There was insufficient evidence to demonstrate a consistent influence of volunteering type or intensity on outcomes. Observational evidence suggested that volunteering may benefit mental health and survival although the causal mechanisms remain

    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 (Pmarriage pattern of their parents with regard to polygyny was similar, and fewer volunteers had fathers in the higher socio-economic class and mothers who had completed secondary education (Pcounseling. 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.

  19. Volunteering as a determinant of civil society

    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.

    Full Text Available Emotional content/context enhances declarative memory through modulation of encoding and retrieval mechanisms. At encoding, neurophysiological data have consistently demonstrated the subsequent memory effect in theta and gamma oscillations. Yet, the existing studies were focused on the emotional content effect and let the emotional context effect unexplored. We hypothesized that theta and gamma oscillations show higher evoked/induced activity during the encoding of visual stimuli when delivered in an emotionally arousing context. Twenty-five healthy volunteers underwent evoked potentials recordings using a 21 scalp electrodes montage. They attended to an audiovisual test of emotional declarative memory being randomly assigned to either emotionally arousing or neutral context. Visual stimulus presentation was used as the time-locking event. Grand-averages of the evoked potentials and evoked spectral perturbations were calculated for each volunteer. Evoked potentials showed a higher negative deflection from 80 to 140 ms for the emotional condition. Such effect was observed over central, frontal and prefrontal locations bilaterally. Evoked theta power was higher in left parietal, central, frontal and prefrontal electrodes from -50 to 300 ms in the emotional condition. Evoked gamma power was higher in the emotional condition with a spatial distribution that overlapped at some points with the theta topography. The early theta power increase could be related to expectancy induced by auditory information processing that facilitates visual encoding in emotional contexts. Together, our results suggest that declarative memory enhancement for both emotional content and emotional context are supported by similar neural mechanisms at encoding, and offer new evidence about the brain processing of relevant environmental stimuli.

    Conceptual clarity on physician volunteer engagement is lacking in the medical literature. The aim of this study was to present a conceptual framework to describe the elements which influence physician volunteer engagement and to explore volunteer engagement within a national educational programme. The context for this study was the Acute Critical Events Simulation (ACES) programme in Canada, which has successfully evolved into a national educational programme, driven by physician volunteers. From 2010 to 2014, the programme recruited 73 volunteer healthcare professionals who contributed to the creation of educational materials and/or served as instructors. A conceptual framework was constructed based on an extensive literature review and expert consultation. Secondary qualitative analysis was undertaken on 15 semistructured interviews conducted from 2012 to 2013 with programme directors and healthcare professionals across Canada. An additional 15 interviews were conducted in 2015 with physician volunteers to achieve thematic saturation. Data were analysed iteratively and inductive coding techniques applied. From the physician volunteer data, 11 themes emerged. The most prominent themes included volunteer recruitment, retention, exchange, recognition, educator network and quasi-volunteerism. Captured within these interrelated themes were the framework elements, including the synergistic effects of emotional, cognitive and reciprocal engagement. Behavioural engagement was driven by these factors along with a cue to action, which led to contributions to the ACES programme. This investigation provides a preliminary framework and supportive evidence towards understanding the complex construct of physician volunteer engagement. The need for this research is particularly important in present day, where growing fiscal constraints create challenges for medical education to do more with less. © Article author(s) (or their employer(s) unless otherwise stated in the text of

    Volunteer caregivers are a critical source of support for the majority of people living with HIV and AIDS in southern Africa, which has extremely high HIV/AIDS prevalence rates. While studies have shown that volunteer caregiving is associated with negative health and socio-economic outcomes, little is known about the positive experiences of volunteers in the home-based care context in South Africa. The purpose of this study is to explore the perception of rewards among volunteers working in home-based care settings. This study uses a qualitative design. Qualitative interviews were conducted with a purposively selected sample of 55 volunteer caregivers using an interview schedule containing open-ended questions. Volunteer caregivers derived intrinsic rewards related to self-growth and personal (emotional and psychological) development on the job; they also derived satisfaction from community members taking a liking for them and expressing a need for their services. Volunteers felt gratified by the improvements in their health behaviours, which were a direct consequence of the experiences of caring for terminally ill patients with AIDS. Extrinsic rewards came from appreciation and recognition shown by patients and community members. Extrinsic rewards also accrued to volunteers when the services they rendered made their patients happy. Perhaps the greatest sources of extrinsic rewards are skills and competencies acquired from training and experience while caring for their patients, and volunteers' ability to make a difference in the community. Insights into volunteer caregiver rewards provide opportunities for policy makers and programme managers to develop a model of home-based care that facilitates the accrual of rewards to volunteers alongside volunteers' traditional duties of patient care. Programme managers could employ these insights in recruiting and assisting volunteers to identify and reflect on rewards in the caregiving situation as a means of reducing the

    Full Text Available Primary care providers are critical in providing and optimizing health care to an aging population. This paper describes the volunteer component of a program (Health TAPESTRY which aims to encourage the delivery of effective primary health care in novel and proactive ways. As part of the program, volunteers visited older adults in their homes and entered information regarding health risks, needs, and goals into an electronic application on a tablet computer. A total of 657 home visits were conducted by 98 volunteers, with 22.45% of volunteers completing at least 20 home visits over the course of the program. Information was summarized in a report and electronically sent to the health care team via clients’ electronic medical records. The report was reviewed by the interprofessional team who then plan ongoing care. Volunteer recruitment, screening, training, retention, and roles are described. This paper highlights the potential role of a volunteer in a unique connection between primary care providers and older adult patients in their homes.

    Several studies have suggested that high levels of computer use are linked to psychopathology. However, there is ambiguity about what should be considered normal or over-use of computers. Furthermore, the nature of the link between computer usage and psychopathology is controversial. The current study utilized the context of age to address these questions. Our hypothesis was that the context of age will be paramount for differentiating normal from excessive use, and that this context will allow a better understanding of the link to psychopathology. In a cross-sectional study, 185 parents and children aged 3-18 years were recruited in clinical and community settings. They were asked to fill out questionnaires regarding demographics, functional and academic variables, computer use as well as psychiatric screening questionnaires. Using a regression model, we identified 3 groups of normal-use, over-use and under-use and examined known factors as putative differentiators between the over-users and the other groups. After modeling computer screen time according to age, factors linked to over-use were: decreased socialization (OR 3.24, Confidence interval [CI] 1.23-8.55, p = 0.018), difficulty to disengage from the computer (OR 1.56, CI 1.07-2.28, p = 0.022) and age, though borderline-significant (OR 1.1 each year, CI 0.99-1.22, p = 0.058). While psychopathology was not linked to over-use, post-hoc analysis revealed that the link between increased computer screen time and psychopathology was age-dependent and solidified as age progressed (p = 0.007). Unlike computer usage, the use of small-screens and smartphones was not associated with psychopathology. The results suggest that computer screen time follows an age-based course. We conclude that differentiating normal from over-use as well as defining over-use as a possible marker for psychiatric difficulties must be performed within the context of age. If verified by additional studies, future research should integrate

  8. Motivation to volunteer among senior center participants.

    Senior centers in the United States play a vital role in the aging continuum of care as the focal points of a community-based system of services targeting independent older adults to promote their social integration and civically engagement. Although several studies have evaluated the diversity of senior center programs, demographic characteristics of participants, and benefits of participation, very few have explored motivations to volunteer among participants. Many senior centers rely on a cadre of participants who volunteer there to assist with programs and meal services. However, a systematic examination of volunteering interests and the rationale for volunteering among senior center participants has been missing from the literature. This mixed-methods study, conducted at a large suburban senior center, explores the interests and motivations of volunteerism among the participants. The study found that there was limited interest in volunteering among senior center participants. Those who were motivated to volunteer wanted to do so in order to stay connected with their community. There was strong interest in volunteering for single events or projects rather than a long-term commitment. Implications for senior centers are discussed.

    1989-01-01

    The preliminary assessment of many radiopharmaceuticals is often carried out with the help of normal volunteers. These volunteers are drawn from the general public, are fully informed of the procedure to be performed and its attendant risks, and in many cases are compensated financially for their trouble. The cooperation of such people is of vital importance to the full understanding of the normal kinetics and metabolism of many new radiopharmaceuticals. The restrictions on the choice of normal volunteers, and the radiation dose limits which must be observed are not explicitly defined in any of the current guidelines, and in this paper we propose a rationale, based upon available information, which sets acceptable limits for volunteers, and provides a framework within which scientists and physicians can work

    This study seeks to provide an in-depth analysis of care-based interaction in the experiences of volunteers working in lenitherapy (pain therapy) through the case study of hospices in Florence, Italy. A qualitative method of data collection was chosen: the field research made use of open-ended questionnaires distributed to trained but unspecialised volunteers (V = 32) and to volunteers with hospital-based medical expertise (PV = 35) acting for the Italian Lenitherapy Foundation (FILe) and operating in hospices within the ex-ASL (Local Health Unit) of Florence. By analysing the 67 questionnaires collected, it has been possible to reconstruct and interpret the interactional dynamics that exist between the various figures present within a hospice, bringing into focus the most salient aspects of both the organisational context and emotional setting. The research experience, by highlighting everyday unseen aspects that are inaccessible to an 'internal' eye, has made it possible to better characterise the dynamics of unsuccessful collaboration between team members and potential areas of conflict. Finally, where these dynamics have been observed, an attempt has been made to outline priorities for change and possible directions to be taken, so as to promote defusing actions and restore synergy and fluidity to the FILe system.

    In order to characterize age-related and chronological changes of the brain, longitudinal studies of aged volunteers were conducted using computed tomography since 1982. The present paper discusses correlations between brain function and findings of MR images which were obtained using a 1.5 T superconductive MR instrument since 1989. A total of 118 volunteers aged 60 to 88 years old with a mean age of 75.0±6.7 participated in the study, which consisted of MRI, EEG recording, the Benton Visual Retention Test and a medical interview. Subjects with a past history or clinical evidence of CVD, head trauma or dementia were excluded from the study. Incidence of T 2 high signal intensity lesions increased with age. Some showing T 1 low signal intensity in the same lesion were considered to be lacunar infarction, over all incidence of which was 24.6%. Numbers of correct responses on the BVRT showed a negative correlation with numbers of T 2 high signal intensity lesions. Although the aged volunteers in the present study could achieve all activity of daily living without any trouble, high cortical function evaluated by visuoperceptual performance of BVRT was somewhat disturbed in participants with multiple T 2 high signal intensity lesions. Brain atrophy seems to be more advanced in groups with T 2 hyper intensity lesions than in the group without them. These findings may support the notion that T 2 high signal intensity lesions are not merely an index of aging but pathologic lesions accompanied with senescence, although further studies including clinico-pathological correlation are necessary to establish this concept.

    Acetaminophen (APAP, paracetamol) mechanism for analgesic and antipyretic outcomes has been largely addressed, but APAP action on cognitive function has not been studied in humans. Animal studies have suggested an improved cognitive performance but the link with analgesic and antipyretic modes of action is incomplete. This study aims at exploring cognitive tests in healthy volunteers in the context of antinociception and temperature regulation. A double-blind randomized controlled study (NCT01390467) was carried out from May 30, 2011 to July 12, 2011. Forty healthy volunteers were included and analyzed. Nociceptive thresholds, core temperature (body temperature), and a battery of cognitive tests were recorded before and after oral APAP (2 g) or placebo: Information sampling task for predecisional processing, Stockings of Cambridge for spatial memory, reaction time, delayed matching of sample, and pattern recognition memory tests. Analysis of variance for repeated measures adapted to crossover design was performed and a two-tailed type I error was fixed at 5%. APAP improved information sampling task (diminution of the number of errors, latency to open boxes, and increased number of opened boxes; all P memory initial thinking time were decreased ( P =0.04). All other tests were not modified by APAP. APAP had an antinociceptive effect ( P body temperature did not change. This study shows for the first time that APAP sharpens decision making and planning strategy in healthy volunteers and that cognitive performance and antinociception are independent of APAP effect on thermogenesis. We suggest that cognitive performance mirrors the analgesic rather than thermic cascade of events, with possibly a central role for serotonergic and cannabinoid systems that need to be explored further in the context of pain and cognition.

    We propose that voluntary work, characterized by social, physical and cognitive activity in later life is associated with fewer cognitive problems and lower dementia rates. We test these assumptions using 3-wave, self-reported, and registry data from the 2010, 2012, and 2014 Swedish National Prescribed Drug Register. We had three groups of seniors in our data: 1) no volunteering (N = 531), 2) discontinuous volunteering (N = 220), and 3) continuous volunteering (N = 250). We conducted a path analysis in Mplus to investigate the effect of voluntary work (discontinuously and continuously) on self-reported cognitive complaints and the likelihood of being prescribed an anti-dementia treatment after controlling for baseline and relevant background variables. Our results indicated that seniors, who continuously volunteered, reported a decrease in their cognitive complaints over time, whereas no such associations were found for the other groups. In addition, they were 2.44 (95%CI [1.86; 3.21]) and 2.46 (95%CI [1,89; 3.24]) times less likely to be prescribed an anti-dementia treatment in 2012 and 2014, respectively. Our results largely support the assumptions that voluntary work in later life is associated with lower self-reported cognitive complaints and a lower risk for dementia, relative to those who do not engage, or only engage episodically in voluntary work.

    Volunteering internationally appeals to health care professionals and students for a variety of reasons and serves a number of purposes. If international voluntarism is to be mutually advantageous, however, host countries, volunteers and project sponsors need to understand how best they can work together and what can be achieved by volunteers for the greatest benefit of all concerned. This paper is intended to contribute to the growing dialogue on international voluntarism and offers suggestions to strengthen its value, from the perspectives of health workers in a developing country and the authors" experiences over the past 30 years. The paper also identifies undesirable side effects and disabling interventions of international initiatives and examines the notions of aid and assistance. One strategy to prepare volunteers for upcoming international efforts as well as to address inequities at home is involvement with underserved populations in our own country.

    Full Text Available This paper develops a study of case of the TRW Automotive Company and analyzes one of its actions of social responsibility developed together with the non-governmental organization (NGO “Mais Vida”. The data exposition searches to show, from the valued point of view, the complexity of the volunteer action and how its relation with an organization may arouse changes in procedures that interfere in the organizational dimension. It is important to emphasize that the results of a volunteer action, in the context of a social responsibility project, cannot be evaluated considering solemnly the tangible aspects but that the symbolic dimension assumes a fundamental role to be analyzed. In the final considerations, some questions about this theme are outlined, calling attention to its unfinished character and to its potentiality for building a learning space of tolerance and alterity.

    With an ageing population, there are increasing numbers of experienced family carers (FCs) who could provide peer support to newer carers in a similar care situation. The aims of this paper are to: (i) use a cross-sectional study design to compare characteristics of volunteers and recipients of a peer support programme for FCs of people with dementia, in terms of demographic background, social networks and psychological well-being; and (ii) use a longitudinal study design to explore the overall impact of the programme on the volunteers in terms of psychological well-being. Data were collected from programmes run in Norfolk, Northamptonshire, Berkshire and four London boroughs between October 2009 and March 2013. The volunteer role entailed empathic listening and encouragement over a 10-month period. Both carer support volunteers (N = 87) and recipient FCs (N = 109) provided baseline demographic information. Data on social networks, personal growth, self-efficacy, service use and well-being (SF-12; EuroQol Visual Analogue Scale; Hospital Anxiety and Depression Scale; Control, Autonomy, Self-Realisation, Pleasure-19) were collected prior to the start of the intervention (N = 43) and at either 3- to 5 month or 10 month follow-up (N = 21). Volunteers were more likely than recipients of support to be female and to have cared for a parent/grandparent rather than spouse. Volunteers were also more psychologically well than support recipients in terms of personal growth, depression and perceived well-being. The longitudinal analysis identified small but significant declines in personal growth and autonomy and a positive correlation between the volunteers' duration of involvement and perceived well-being. These findings suggest that carers who volunteer for emotional support roles are resilient and are at little psychological risk from volunteering. © 2016 John Wiley & Sons Ltd.

The shortcomings include the lack of surveillance over the scientific validity of the protocol and its ethical review, and over the financial inducements to volunteers. Recruitment is open to abuse because the volunteers may have some allegiance to the investigators. There is an urgent need to institute checks on these aspects. Most important, however, is the lack of legal safeguards for volunteers taking part in research done outside the pharmaceutical industry. The suggested procedure for obtaining consent, for health checks, and for providing compensation can be equitable to all concerned, and yet not restrict initiative, nor curtail research aims.

    Computer games have attracted remarkable attentions in general publics with different cultures and their effects are subject of research by cognitive neuroscientists. In the present study, possible effects of the game Fifa 2015 on cognitive performance, hormonal levels, and electroencephalographic (EEG) signals were evaluated in young male volunteers. Thirty two subjects aged 20 years on average participated mutually in playing computer game Fifa 2015. Identification information and general knowledge about the game were collected. Saliva samples from the contestants were obtained before and after the competition. Perceptive and cognitive performance including the general cognitive health, response delay, attention maintenance, and mental fatigue were measured using PASAT test. EEG were recorded during the play using EEG device and analyzed later using QEEG. Simultaneously, the players' behavior were recorded using a video camera. Saliva cortisol levels were assessed by ELISA kit. Data were analyzed by SPSS program. The impact of playing computer games on cortisol concentration of saliva before and after the game showed that the amount of saliva plasma after playing the game has dropped significantly. Also the impact of playing computer games on mental health, before and after the game indicated that the number of correct answers has not changed significantly. This indicates that sustained attention has increased in participants after the game in comparison with before that. Also it is shown that mental fatigue measured by PASAT test, did not changed significantly after the game in comparison to before that. The impact of game on changes in brain waves showed that the subjects in high activity state during playing the game had higher power of the EEG signals in most of the channels in lower frequency bands in compared to normal state. The present study showed that computer games can positively affect the stress system and the perceptual-cognitive system. Even though

    Healthcare as a worldwide industry is experiencing a period of growth based on health information technology. The capabilities of cloud systems make it as an option to develop eHealth goals. The main objectives of the present study was to evaluate the advantages and limitations of health information systems implementation in a cloud-computing context that was conducted as a systematic review in 2016. Science direct, Scopus, Web of science, IEEE, PubMed and Google scholar were searched according study criteria. Among 308 articles initially found, 21 articles were entered in the final analysis. All the studies had considered cloud computing as a positive tool to help advance health technology, but none had insisted too much on its limitations and threats. Electronic health record systems have been mostly studied in the fields of implementation, designing, and presentation of models and prototypes. According to this research, the main advantages of cloud-based health information systems could be categorized into the following groups: economic benefits and advantages of information management. The main limitations of the implementation of cloud-based health information systems could be categorized into the 4 groups of security, legal, technical, and human restrictions. Compared to earlier studies, the present research had the advantage of dealing with the issue of health information systems in a cloud platform. The high frequency of studies conducted on the implementation of cloud-based health information systems revealed health industry interest in the application of this technology. Security was a subject discussed in most studies due to health information sensitivity. In this investigation, some mechanisms and solutions were discussed concerning the mentioned systems, which would provide a suitable area for future scientific research on this issue. The limitations and solutions discussed in this systematic study would help healthcare managers and decision

This is in line with previous research, that religious attendance is related positively to volunteering. These results confirm the idea that support of the religious attributes community plays quite a large role in volunteering process. However, it a bear that volunteering is not only dependent on religious community, but also on individual motivation.

    The notion of context has been widely studied and there are several authors that have proposed different definitions of context. However, context has not been widely studied in the framework of human mobility and the notion of context has been imported directly from other computing fields without specifically addressing the tourism domain requirements. In order to store and manage context information a context data model and a context management platform are needed. Ontologies have been widely used in context modelling, but many of them are designed to be applied in general ubiquitous computing environments, do not contain specific concepts related to the tourism domain or some approaches do not contain enough concepts to represent context information related to the visitor on the move. That is why we propose a new approach to provide a better solution to model context data in tourism environments, adding more value to our solution reusing data about tourist resources from an Open Data repository and publishing it as Linked Data. We also propose the architecture for a context information management platform based on this context data model.

    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.

  20. Generation Z’s Sustainable Volunteering: Motivations, Attitudes and Job Performance

    Full Text Available Generation Z (Gen Z, the future of America’s workforce, is forecasted to represent more than 30 million persons by 2020. Volunteer rates have been declining since 2002. Most compelling is that overall lowest volunteer rates were found to be within the Gen Z segment, with expectations of continued decline. Thus, this study explored motivations associated with sustainable volunteering by Gen Z based upon past research that documented intent to volunteer is strongly associated with age. In doing so, the Volunteer Functions Inventory was adopted to identify Gen Z motivations for volunteering. This study then employed the theory of planned behavior to test the relationships between Gen Z volunteering motivations, their attitudes and job performance using data obtained from 306 Gen Z volunteer special event participants. Among five motives identified to be important to Gen Z, only four motives (“value”, “career”, “learning” and “self-esteem” were found to significantly influence their attitudes. The ‘social’ motive was found to have no significant effect on their attitudes towards volunteering. This research framework was supported by validating the significant relationships between volunteer motivations, attitudes and job performance specific to the Gen Z volunteer segment. “Job training appropriateness” was found to be an important moderator for improving the relationships between Gen Z volunteer attitudes and job performance.

    Vitulli, W F; McNeil, M J

    1990-12-01

    This exploratory investigation concerned the effects of both auditory and visual context variations on the immediate recall of a series of digits presented on a computer screen (CRT). 5 intensities of background noise and 5 background hues were presented randomly to 110 undergraduate volunteers as they studied 25 numerals ranging from 1 to 5 at rates of change of either 1 or 3 sec. per numeral timed from the onset of the previous numeral. A 2 x 2 x 5 mixed split-plot factorial analysis of variance gave a significant difference in mean immediate-recall scores between rates of digit presentation with better recall associated with the 3-sec. rate. There was no significant main effect in recall scores for auditory vs color contexts, yet a post hoc analysis of variance for successive stages followed by Scheffé comparisons showed that across auditory intensities, Stages 3 and 4 and 5 (combined) had significantly higher immediate recall scores than Stages 1 and 2 (combined). This improvement across stages was not found under the visual (color) series. There was a three-way interaction for modality-contexts x rates x levels explained by the partitioning of stages which differed for auditory and for visual contexts. Results are discussed in terms of effects of modality.

    2018-03-02

    The present study examines the association between formal volunteering and cognitive functioning over time. We also examine the moderating roles of race, sex, education, and time. Using 11,100 participants aged 51 years and older and nine waves of data from the Health and Retirement Survey, we simultaneously modeled the longitudinal associations between engaging in formal volunteering and changes in cognitive functioning using multilevel models. Formal volunteering was associated with higher levels of cognitive functioning over time, especially with aspects of cognitive functioning related to working memory and processing. This association was stronger for women than it was for men, and for those with below average levels of education. The positive association between formal volunteering and cognitive functioning weakened over time when cognitive functioning was conceptualized as memory, but strengthened over time when conceptualized as working memory and processing. Volunteering is a productive activity that is beneficial not just to society, but to volunteers' levels of cognitive functioning in older age. For women and those with lower levels of education, formal volunteering appears particularly beneficial to working memory and processing. © The Author 2017.

    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

  9. Court Appointed Volunteers for Abused and Neglected Children.

    Justin, Renate G.

    2002-02-01

    A court appointed special advocate (CASA) volunteer is a trained citizen who is appointed by a judge to represent the best interests of an abused and neglected child in court. An independent voice, the volunteer gathers information and reports to the court. The CASA volunteer works in close cooperation with other professionals, physicians, lawyers, social workers, and teachers to find the most suitable permanent placement for a victimized child, whether it be a foster home, parental home, or adoptive home. Another function for CASA volunteers is to be supportive to the child during a time of uncertainty in his or her life and to help the youngster adjust to new and changing situations; the CASA volunteer may be the only consistent adult presence during this difficult period of transition.

    Welk, T A

    1992-01-01

    Volunteers are integral members of the hospice interdisciplinary team. They are distinguished from other members of the team only by role, not by expectation. The distinction is not between "volunteer" and "professional," because every team member is to be professional in the best sense of that word. If a distinction is to be made, it is that some hospice staff members are salaried while others donate their services. Volunteer staff members are expected to be as responsible and accountable as every other member of the team. ALL staff members must realize the importance of taking care of personal needs in order to be able to care for others. Even though the following article deals primarily with the volunteer hospice staff member, the points outlined can just as easily be applied to the salaried staff member.

  15. Volunteer Environmental Stewardship and Affective Labour in Philadelphia

    Directory of Open Access Journals (Sweden)

    Alec Foster

    2018-01-01

    Full Text Available Recent research has critically evaluated the rapid growth of volunteer urban environmental stewardship. Framings of this phenomenon have largely focused upon environmentality and/or neoliberal environments, unfortunately often presenting a totalising picture of the state and/or market utilising power from above to create environmental subjects with limited agency available to local citizens. Based upon qualitative research with volunteer urban environmental stewards in Philadelphia, affective labour is proposed as an alternative explanation for participation. Stewards volunteered their time and labour due to the intense emotional attachments they formed with their neighbourhoods, neighbours, and nonhuman others in relationships of affective labour. Volunteer urban environmental stewardship as affective labour provides room for agency on the part of individuals and groups involved in volunteer urban environmental reproduction and opens up new ways of relating to and being with human and nonhuman others.

    2010-11-01

    As populations age, there will be a need for more volunteers in social welfare, and consequently a need to better understand potential effects of volunteering for older people. Whilst there is a body of international literature exploring health benefits of volunteering in later life, there are currently no longitudinal studies of Australian populations. Internationally, there is a lack of studies focusing on older women, who comprise the majority of the ageing population. The aim of this article was to explore the relationship between volunteering and psychosocial and health factors for a cohort of older Australian women over time. Data for this study were from the oldest cohort of Australian Longitudinal Study on Women's Health, a 20-year longitudinal survey of Australian women aged 70-75 years in 1996. Volunteering status was the factor of interest and study factors included a broad range of demographic, health and social factors. A longitudinal model was developed for mediators of volunteering over time. Of 7088 women in 2005, 24.5% reported actively volunteering, 15.5% were continuing, 7.5% were new, 15.3% were intermittent and 34.7% had never been volunteers. Volunteering was associated with increased quality of life and social support. Women were more likely to continue volunteering over time if they lived in a rural area, had higher socioeconomic indicators, and better levels of physical and mental health. This study contributes to the literature on the relationship between volunteering and health for older women. Understanding the potential health implications of volunteering is a critical issue in current policy debates.

    Full Text Available Ashwagandha (Withania somnifera (WS, a "rasayana" drug, is recommended for balavardhan and mamsavardhan. The study was intended to evaluate dose-related tolerability, safety, and activity of WS formulation in normal individuals. The design was prospective, open-labeled, variable doses in volunteers. Eighteen apparently healthy volunteers (12M:6F, age:18-30 years, and BMI: 19-30 were enrolled. After baseline investigations, they received WS capsules (Rx (aqueous extract, 8:1 daily in two divided doses with increase in daily dosage every 10 days for 30 days (750 mg/day x10 days, 1 000 mg/day x 10 days, 1 250 mg/day x 10 days. Volunteers were assessed for symptoms/signs, vital functions, hematological and biochemical organ function tests. Muscle activity was measured by hand grip strength, quadriceps strength, and back extensor force. Exercise tolerance was determined using cycle ergometry. Lean body weight and fat% were computed from skin fold thickness measurement. Adverse events were recorded, as volunteered by the subjects. Repeated measures ANOVA, McNemar′s test, and paired t test were employed. All but one volunteer tolerated WS without any adverse event. One volunteer showed increased appetite, libido, and hallucinogenic effects with vertigo at the lowest dose and was withdrawn from study. In six subjects, improvement in quality of sleep was found. Organ function tests were in normal range before and after the intervention. Reduction in total- and LDL- cholesterol and increase of strength in muscle activity was significant. Total body fat percentage showed a reduction trend. WS, in escalated dose, was tolerated well. The formulation appeared safe and strengthened muscle activity. In view of its traditional Rasayana use, further studies are planned to evaluate potential of this drug in patients of sarcopenia.

    A total of 34 dynamic matched frontal sled tests were performed, 17 low (2.5g, Δv=4.8kph) and 17 medium (5.0g, Δv=9.7kph), with five male human volunteers of approximately 50th percentile height and weight, a Hybrid III 50th percentile male ATD, and three male PMHS. Each volunteer was exposed to two impulses at each severity, one relaxed and one braced prior to the impulse. A total of four tests were performed at each severity with the ATD and one trial was performed at each severity with each PMHS. A Vicon motion analysis system, 12 MX-T20 2 megapixel cameras, was used to quantify subject 3D kinematics (±1mm) (1kHz). Excursions of select anatomical regions were normalized to their respective initial positions and compared by test condition and between subject types. The forward excursions of the select anatomical regions generally increased with increasing severity. The forward excursions of relaxed human volunteers were significantly larger than those of the ATD for nearly every region at both severities. The forward excursions of the upper body regions of the braced volunteers were generally significantly smaller than those of the ATD at both severities. Forward excursions of the relaxed human volunteers and PMHSs were fairly similar except the head CG response at both severities and the right knee and C7 at the medium severity. The forward excursions of the upper body of the PMHS were generally significantly larger than those of the braced volunteers at both severities. Forward excursions of the PMHSs exceeded those of the ATD for all regions at both severities with significant differences within the upper body regions. Overall human volunteers, ATD, and PMHSs do not have identical biomechanical responses in low-speed frontal sled tests but all contribute valuable data that can be used to refine and validate computational models and ATDs used to assess injury risk in automotive collisions.

    2012-01-01

    The purpose of this study is to examine the effects of motives for volunteering on respondents' mortality risk 4 years later. Logistic regression analysis was used to examine whether motives for volunteering predicted later mortality risk, above and beyond volunteering itself, in older adults from the Wisconsin Longitudinal Study. Covariates included age, gender, socioeconomic variables, physical, mental, and cognitive health, health risk behaviors, personality traits, received social support, and actual volunteering behavior. Replicating prior work, respondents who volunteered were at lower risk for mortality 4 years later, especially those who volunteered more regularly and frequently. However, volunteering behavior was not always beneficially related to mortality risk: Those who volunteered for self-oriented reasons had a mortality risk similar to nonvolunteers. Those who volunteered for other-oriented reasons had a decreased mortality risk, even in adjusted models. This study adds to the existing literature on the powerful effects of social interactions on health and is the first study to our knowledge to examine the effect of motives on volunteers' subsequent mortality. Volunteers live longer than nonvolunteers, but this is only true if they volunteer for other-oriented reasons.

    2015-09-01

    Existing literature has shown that volunteering is related to better physical and mental health outcomes. The purpose of this study is to examine whether personality traits and volunteering are independent predictors of physical and mental health. The current study utilizes data from the St. Louis Personality and Aging Network (SPAN), a representative sample of community-based adults between the ages of 55 and 64. Using hierarchical linear regressions, we test whether volunteering is a significant predictor of both physical and mental health while controlling for personality traits. We find that volunteering is not significantly related to either physical or mental health while controlling for personality traits. We also find that lower neuroticism is related to better physical functioning and mental health, whereas higher extraversion is related to better mental health. These results indicate that volunteering may be related to health outcomes because of the personality characteristics of volunteers, not the volunteering experience in and of itself. Future longitudinal studies are needed to further explore the relationship between personality, volunteering, and health. © The Author 2014.

    2017-03-01

    Full Text Available In recent years, the administrators of public library administrators have been actively promoting children’s reading services. In particular, storytelling activities have a significantly positive effect on enhancing children’s interest and ability in reading. Because of human resource shortages at public libraries, providing these services depends on volunteers. The public libraries should enhance the competencies of volunteers who engage in storytelling, and provide appropriate training for maintaining as well as improving the effectiveness of storytelling services. Therefore, this study was conducted to examine the storytelling training of storytelling volunteers. The study used in-depth interviews to obtain information on the experiences, ideas, and suggestions of public library storytelling volunteers at Taipei Public Library. Current education and training of storytelling volunteer encompasses demand analysis, implementation methods, course content, assessment of effectiveness, and suggestions for adjusting education and training in public library. Finally, the present study results are provided for education and training of storytelling volunteers for public libraries.

    2018-01-24

    The demand for international volunteer experiences to promote global health and nutrition is increasing and numerous studies have documented the experiences of the international volunteers who travel abroad; however, little is known about effective practices from the perspective of partner organizations. This study aims to understand how variables such as the skill-level of volunteers, the duration of service, cultural and language training, and other key variables affect partner organizations' perceptions of volunteer effectiveness at promoting healthcare and nutrition. This study used a cross-sectional design to survey a convenience sample of 288 volunteer partner organizations located in 68 countries. Principle components analyses and manual coding of cases resulted in a categorization of five generalized types of international volunteering. Differences among these types were compared by the duration of service, skill-level of volunteers, and the volunteers' perceived fit with organizational needs. In addition, a multivariate ordinary least square regression tested associations between nine different characteristics/activities and the volunteers' perceived effectiveness at promoting healthcare and nutrition. Partner organizations viewed highly-skilled volunteers serving for a short-term abroad as the most effective at promoting healthcare and nutrition in their organizations, followed by slightly less-skilled long-term volunteers. The greatest amount of variance in perceived effectiveness was volunteers' ability to speak the local language, followed by their skill level and the duration of service abroad. In addition, volunteer training in community development principles and practices was significantly related to perceived effectiveness. The perceptions of effective healthcare promotion identified by partner organizations suggest that program and volunteer characteristics need to be carefully considered when deciding on methods of volunteer preparation and

    Full Text Available Sunflower (Helianthus annuus sown offseason, after soybean crop (Glycine max, is affected by the competition imposed by volunteer plants. Two experiments were carried out to evaluate the control of volunteer soybean plants in sunflower crops. The sulfentrazone herbicide (75 g ha-1, 100 g ha-1 and 250 g ha-1 causes phytotoxicity to sunflower immediately after application, however, plants recover, with no yield losses. These doses do not cause the total death of volunteer soybean plants, but temporarily paralyzes their growth, avoiding the competition with the sunflower crop. The glufosinate ammonium and ametryn herbicides are effective in controlling volunteer soybean plants, however, symptoms of phytotoxicity in the sunflower crop are high, reflecting in losses of dry weight biomass and crop yield. The other treatments do not provide satisfactory control of volunteer soybean plants and even reduce the sunflower dry weight biomass and yield.

    This study investigated race differences in the relationship between formal volunteering and hypertension prevalence among middle-aged and older adults. Using data from the 2004 and 2006 Health and Retirement Study (N = 5,666; 677 African Americans and 4,989 whites), we examined regression models stratified by race to estimate relationships among hypertension prevalence, systolic and diastolic blood pressure, and volunteer status and hours spent volunteering among persons aged 51 years old and older. White volunteers had a lower risk of hypertension than white nonvolunteers. A threshold effect was also present; compared with nonvolunteers, volunteering a moderate number of hours was associated with lowest risk of hypertension for whites. Results for hypertension were consistent with results from alternative models of systolic and diastolic blood pressure. We found no statistically significant relationship between volunteering activity and hypertension/blood pressure for African Americans. There may be unmeasured cultural differences related to the meaning of volunteering and contextual differences in volunteering that account for the race differences we observed. Research is needed to determine the pathways through which volunteering is related to hypertension risk and that may help explain race differences identified here.

    Krause, Neal; Ironson, Gail; Hill, Peter C

    2017-04-01

    Research indicates that greater involvement in volunteer activities is associated with better health. We aim to contribute to this literature in two ways. First, rather than rely on self-reports of health, measured resting pulse rates serve as the dependent variable. Second, an effort is made to see if religious commitment moderates the relationship between volunteering and resting pulse rates. Data that come from a recent nationwide survey (N = 2265) suggest that volunteer work is associated with lower resting pulse rates. The results also reveal that the relationship between engaging in volunteer work and resting pulse rates improves among study participants who are more deeply committed to religion.

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

    2017-06-01

    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.

  15. Effects of chewing gum on cognitive function, mood and physiology in stressed and non-stressed volunteers.

    Smith, Andrew

    2010-02-01

    Recent research suggests that chewing gum may improve aspects of cognitive function and mood. There is also evidence suggesting that chewing gum reduces stress. It is important, therefore, to examine these two areas and to determine whether contextual factors (chewing habit, type of gum, and personality) modify such effects. The aims of the present study were: (i) to determine whether chewing gum improved mood and mental performance; (ii) to determine whether chewing gum had benefits in stressed individuals; and (iii) to determine whether chewing habit, type of gum and level of anxiety modified the effects of gum. A cross-over study involving 133 volunteers was carried out. Each volunteer carried out a test session when they were chewing gum and without gum, with order of gum conditions counterbalanced across subjects. Baseline sessions were conducted prior to each test session. Approximately half of the volunteers were tested in 75 dBA noise (the stress condition) and the rest in quiet. Volunteers were stratified on chewing habit and anxiety level. Approximately, half of the volunteers were given mint gum and half fruit gum. The volunteers rated their mood at the start and end of each session and had their heart rate monitored over the session. Saliva samples were taken to allow cortisol levels (good indicator of alertness and stress) to be assayed. During the session, volunteers carried out tasks measuring a range of cognitive functions (aspects of memory, selective and sustained attention, psychomotor speed and accuracy). Chewing gum was associated with greater alertness and a more positive mood. Reaction times were quicker in the gum condition, and this effect became bigger as the task became more difficult. Chewing gum also improved selective and sustained attention. Heart rate and cortisol levels were higher when chewing which confirms the alerting effect of chewing gum. Overall, the results suggest that chewing gum produces a number of benefits that are

    The ATLAS collaboration has recently setup a number of citizen science projects which have a strong IT component and could not have been envisaged without the growth of general public computing resources and network connectivity: event simulation through volunteer computing, algorithms improvement via Machine Learning challenges, event display analysis on citizen science platforms, use of open data, etc. Most of the interactions with volunteers are handled through message boards, but specific outreach material was also developed, giving an enhanced visibility to the ATLAS software and computing techniques, challenges and community. In this talk the Atlas Computing Agora (ACA) web platform will be presented as well as some of the specific material developed for some of the projects.

  17. Volunteering and mortality risk: a partner-controlled quasi-experimental design.

    O'Reilly, Dermot; Rosato, Michael; Moriarty, John; Leavey, Gerard

    2017-08-01

    The consensus that volunteering is associated with a lower mortality risk is derived from a body of observational studies and therefore vulnerable to uncontrolled or residual confounding. This potential limitation is likely to be particularly problematic for volunteers who, by definition, are self-selected and known to be significantly different from non-volunteers across a range of factors associated with better survival. This is a census-based record-linkage study of 308 733 married couples aged 25 and over, including 100 571 volunteers, with mortality follow-up for 33 months. We used a standard Cox model to examine whether mortality risk in the partners of volunteers was influenced by partner volunteering status-something expected if the effects of volunteering on mortality risk were due to shared household or behavioural characteristics. Volunteers were general more affluent, better educated and more religious than their non-volunteering peers; they also had a lower mortality risk [hazard ratio (HR)adj = 0.78: 95% confidence interval (CI) = 0.71, 0.85 for males and HRadj = 0.77: 95% CI = 0.68, 0.88 for females]. However, amongst cohort members who were not volunteers, having a partner who was a volunteer was not associated with a mortality advantage (HRadj = 1.01: 95% CI = 0.92, 1.11 for men and HRadj = 1.00: 95% CI = 0.88, 1.13 women). This study provides further evidence that the lower mortality associated with volunteering is unlikely to be due to health selection or to residual confounding arising from unmeasured selection effects within households. It therefore increases the plausibility of a direct causal effect. © The Author 2017; all rights reserved.

    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.

  1. A Framework for Developing Context-aware Systems

    2014-09-01

    Full Text Available Context-aware computing refers to a general class of mobile real-time reactive systems that continuously sense their physical environment, and adapt their behavior accordingly. Context-awareness is an essential inherent property of ubiquitous computing or pervasive computing systems. Such systems are much richer and more complex than many software systems. The richness mainly comes from context-awareness, the heterogeneity of mobile devices and their service types, while complexity arises in the multitude of adaptations enforced by system policies. In order to provide the true intended effect on the application of services without compromising on the richness, the complexity must be tamed. Towards this goal, this paper proposes a component-based architecture for a Context-aware Framework in which context, awareness capabilities, reactions, and adaptations are formally dealt with. Two formal languages are designed to express context situations and express workflow policies, which respectively lead to a context reasoner and to enforce adaptations.With these formalisms and a component design that can be formalized, this work fulfills a formal approach to construct context-aware applications. Two case studies are explained, of which one is a proof-of-concept case study from service-oriented domain. It is fully implemented to illustrate the expressiveness of the framework design and robustness of its implementation.

    2010-01-01

    Full Text Available Although there is a significant body of work concerning voluntary work, hardly any attention is given to volunteering of older individuals. Moreover, the potential volunteers among older adults is even less examined. Next to volunteering among olde r adults, the neighbou rhood becomes more salient when people age and this due to their more intense use and time spent in the neighbourhood. In response to these lacunae, the main purpose of this contribution is to examine the impact of subjective neighbourhood features on the recruitment potential for volunteering among older people. This study uses data collected from the Belgian Ageing Studies. 59.977 adults aged sixty and over living self-reliantly in 127 Flemish municipalities in Belgium participated in this study. A binary logistic regression is ap plied to analyse the key va riables characterizing potential volunteers. Our findings stress the need for recognizing the crucial importance of the locality when recruiting older adults for volunteer activities.

  3. Embedding Volunteer Activity into Paramedic Education.

    2017-01-01

    Paramedics require a wide range of skills that are beyond clinical or technical skills in order to meet the demands of the role and provide quality and compassionate care to patients. Non-technical or "soft" skills and attributes are generally challenging to teach and develop in the classroom setting. Volunteerism provides an opportunity for students to gain exposure to different communities and develop interpersonal skills. This cross-sectional study used one-on-one interviews with 12 third-year Bachelor of Emergency Health (Paramedic) students from Monash University, Australia, who completed a community volunteering program. Results suggest that paramedic students see volunteering as a highly valuable means of developing a number of skills crucial to their future roles and paramedic practice. Volunteering also provided students with an opportunity to learn about themselves and the broader community, develop confidence, and improve overall job-readiness and employability. This study demonstrates that embedding volunteering into paramedic education is an effective way to develop the broad range of paramedic attributes required for the role. These experiences allow students to make the important transition to a job-ready graduate paramedic who can provide holistic patient-centred care.

    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.

    2017-09-01

    Despite the renewed interest in youth volunteering in recent years, there remain major gaps in our knowledge of its consequences. Drawing data from the National Longitudinal Study of Adolescent to Adult Health, we examine the long-term effects of youth volunteering on the civic and personal aspects of volunteers' lives. Our results suggest that youth volunteering has a positive return on adult volunteering only when it is voluntary, and that net of contextual factors neither voluntary nor involuntary youth service has a significant effect on adult voting. Regarding personal outcomes, our findings indicate that the psychological benefits of youth volunteering accrue only to voluntary participants, whereas both voluntary and involuntary youth service are positively associated with educational attainment and earnings in young adulthood. Taken together, these results lend support to the case for youth volunteer programs, though the civic benefits of these programs appear to be less dramatic than generally suggested.

  13. 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.

    2009-01-01

    To compare the long-term psychological functioning of 3 groups of survivors of traumatic brain injury (TBI): (1) those who report being regularly active either by working or studying, (2) those who are not competitively employed but are active volunteers, and (3) those who report neither working, studying, nor volunteering. PARTICIPANTS AND PROCEDURE: Two hundred eight participants aged 16 years and older with minor to severe TBI were classified as (1) Working/Studying (N = 78), (2) Volunteering (N = 54), or (3) Nonactive (N = 76). Measures of psychological distress (anxiety, depression, cognitive disturbance, irritability/anger), fatigue, sleep disturbance, and perception of pain. Survivors of TBI who report being active through work, studies, or volunteering demonstrate a significantly higher level of psychological adjustment than persons who report no activity. Even among participants who are unable to return to work and are declared on long-term disability leave, those who report engaging in volunteer activities present significantly better psychological functioning than participants who are nonactive. Volunteering is associated with enhanced psychological well-being and should be encouraged following TBI.

  15. [Drug evaluation in healthy volunteers. Legislative and ethical aspects].

    Science.gov (United States)

    Warot, D

    1991-01-01

    Studies in healthy volunteers have been legalized since December 20th 1988 in France. The healthy volunteer is employed for a variety of studies in phases I and IV of drug development. This type of research can equally be called nontherapeutic in nature. Every experiment involving healthy volunteers should be approved by the Ethics Committee. Using volunteers within the department, company or other organisation, while offering advantages for the investigator should be prohibited as freedom of concept might not be safeguarded. As well, financial incentives may over-persuade individuals, including students, who have low incomes and promote the "professional volunteer". To avoid this problem, French law planned a national register. The potential benefits of such a disposition are still unknown. Having been given appropriate information concerning the drug trial, his obligations and rights, the healthy volunteer gives his written consent. Specific recommendations for nontherapeutic assessments of drug effects are given concerning prisoners, the mentally handicapped, women with a risk of frequency, children. Ethical considerations concerning research on a healthy population must go beyond the law recently promulgated in France.

    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.

    The most common opportunities for nurse anesthetists to be involved in volunteer anesthesia overseas are usually on a surgical team to provide direct care for selected types of patients or to be involved in teaching local anesthesia providers. The challenges are numerous and unique in each setting. Sharing of knowledge, directly as an instructor or indirectly as a provider, provides for a great impact on health care delivery in many emerging nations. The anesthesia provider who is working to deliver care in another country must consider many variables before taking on such a venture. The type of surgical team or teaching assignment one accepts will determine the type of preparation that must be done before departing. In addition to the many organizational items, one should consider some personal issues as well. Lost wages, transportation costs, and lodging expenses are often paid for by the volunteer. Time away from one's family may also be a consideration. Health care, such as updated immunizations, must be attended to before to departure. Volunteers must be able to provide good care in less than ideal situations, and often with much less equipment and medications than are available in the United States. A review of some of the issues that one should consider before deciding to be a volunteer are outlined in this article. The nurse anesthetist who successfully anticipates and deals with the challenges of volunteer anesthesia will be rewarded with an intense degree of personal satisfaction. The ability to give back to the profession and those who would otherwise not have access to one's skills or knowledge produces a sense of accomplishment that is unique.

    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.

    Many patients approaching death experience hopelessness, helplessness, and a depressed mood, and these factors can contribute to a difficult end-of-life (EoL) period. Biography services may assist patients in finding meaning and purpose at this time. The aim of our study was to investigate the lived experience of volunteers involved in a biography service in Melbourne, Australia, using a qualitative methodology. The participants were 10 volunteers who had participated in a biography service within a private palliative care service. Each volunteer was interviewed separately using a study-specific semistructured interview guide. The transcripts of these interviews were then subjected to thematic analysis. Analysis yielded the following themes: motivations for volunteering; dealing with death, dying, and existential issues; psychosocial benefits of volunteering; and benefits and challenges of working with patients and their families. Our results indicated that volunteering gave the volunteers a deeper appreciation of existential issues, and helped them to be more appreciative of their own lives and gain a deeper awareness of the struggles other people experience. They also suggested that volunteers felt that their involvement contributed to their own personal development, and was personally rewarding. Furthermore, the results highlighted that volunteers found that encounters with family members were sometimes challenging. While some were appreciative, others imposed time limits, became overly reliant on the volunteers, and were sometimes offended, hurt, and angered by what was included in the final biography. It is hoped that the findings of the current study will provide direction for improvements in the biography services that will benefit patients, family members, and volunteers. In particular, our findings highlight the need to provide ongoing support for volunteers to assist them in handling the challenges of volunteering in a palliative care setting.

    Full Text Available European Years are a means of promoting European issues at a macro and micro-level. The objective of this paper is to provide the visual differences in the framing of the issue of volunteering at a European and national level. The approach focuses on a blending of two qualitative research methods in visual communication: ATLAS.ti (computer assisted/ aided qualitative data analysis software and social semiotics. The results of our analysis highlight two network views on volunteering promoted through videos, a salience of transactional processes in the implementation of volunteering at a European and national level, and a classification of various types of social practices specific to Romania. This study provides an insight into the way in which two different qualitative methods may be combined in order to provide a visual representation and interpretation to a European issue.

    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. © The Author(s) 2014.

    2014-06-01

    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. 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. Qualitative study of key informant interviews. Stakeholders of a short-term international medical volunteer (IMV) placement programme in Nepal. 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. 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. 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. © British Journal of General Practice 2014.

    Abstract   Background: Volunteering in sport is the most popular and media form of pro-social work in Europe. In Poland, to such activity the conditions are still creating by the largest growth of numbers of institutions active in the public sector in the field of sport, recreation, tourism and hobbies. Interest in volunteering at sport events is increasing, especially among young people. The media image of sport volunteering is adopted by the organizer with chosen promotional strategy. The associated expectations of the participants, their motivation and style of behaving during participation in volunteer project as a consequence are also factors determining the media image of sport volunteering.   Aim: The aim of the study is to compare the style of engaging in social work of their participants and motives of taking that kind of work by volunteers working in Poznan. Material and Method: The analysis included data available on the Internet regarding to organization of volunteer work during the UEFA Euro 2012™ in Poland and Ukraine as well as literature review regarding to the motivation to unpaid work in Poland. The motives of engaging in to volunteering as well as style of that work was compared between groups of participants of volunteering at UEFA Euro 2012™ in Poznan and Poland.   Results: Volunteering at UEFA Euro 2012™ was separated on two areas, sports and urban and was coordinated by different organizers. The convergence between the motivational climate created by organizers of two independent volunteer projects at UEFA Euro 2012™ and motives for social work of its participants is visible. Encouraging volunteers to unpaid work in sport area of tournament by presenting it as a possibility to feel the sports atmosphere was similar to motives and significant more often reported by its volunteers than volunteers working in urban zone. Altruistic motives underlying in social activities significantly more often were reported by volunteers working in

    This paper describes a study that was undertaken to investigate the effects of participating in a community volunteering programme (the Community Mothers Programme) on volunteers (Community Mothers). The aim of the study was to investigate if volunteering in this programme acted as a pathway to lifelong learning; did the volunteers recognise the learning of new knowledge and/or skills, and did their participation in the programme trigger them to progress to further education in other settings? A self-administered questionnaire method was used for data collection: 115 questionnaires being distributed to volunteers, with a response rate of eighty-two (71 per cent). Findings show that the majority of the respondents cited the learning of new knowledge and/or skills as a result of their participation in the Community Mothers Programme. Learning appeared to stem from the various training and activities, suggesting an educational process within the volunteer setting. Findings also show that the majority of respondents had progressed to further education. In this instance, therefore, volunteering did appear to act as a pathway to lifelong learning.

    Full Text Available While research has been conducted concerning the effects of school-based mentoring on atrisk students, limited work has focused on the volunteer mentors. This study examined the motivations of adult volunteers and the benefits of their participation in a six-month,school-based mentoring program. 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.

  11. Volunteering in the Community: Potential Benefits for Cognitive Aging.

    2018-03-02

    This review aims to advance understanding of the potential benefits of volunteering in the community for older adults' cognitive functioning by taking an in-depth look at the relevant evidence to date. This review describes the main pathways through which volunteering could plausibly benefit cognitive functioning and critically examines research that has specifically investigated links between volunteering and cognition. Fifteen articles that assessed in adults aged ≥ 55 years the relationship between volunteering (predictor) and cognitive functioning (outcome) were identified via literature database searches. On balance, evidence from the small number of relevant studies to date supports the idea that volunteering can protect against cognitive aging with respect to global functioning and at least some specific cognitive domains. Studies that used robust designs and assessed domain-specific cognitive functioning produced the largest effect sizes. To help advance the field, this review puts forward recommendations for future research, with an emphasis on the need for robust study designs and specific investigations into the nature and extent of the cognitive benefits of volunteering. Through that work, researchers can determine how a simple and accessible activity like volunteering can best be used to help reduce the burden of age-related cognitive decline. © The Author 2017.

    Although the health benefits of volunteering have been well documented, no research has examined its cumulative effects according to other-oriented and self-oriented volunteering on multiple health outcomes in the general adult public. This study examined other-oriented and self-oriented volunteering in cumulative contribution to health outcomes (mental and physical health, life satisfaction, social well-being and depression). Data were drawn from the Survey of Texas Adults 2004, which contains a statewide population-based sample of adults (n = 1504). Multivariate linear regression and Wald test of parameters equivalence constraint were used to test the relationships. Both forms of volunteering were significantly related to better health outcomes (odds ratios = 3.66% to 11.11%), except the effect of self-oriented volunteering on depression. Other-oriented volunteering was found to have better health benefits than did self-volunteering. Volunteering should be promoted by public health, education and policy practitioners as a kind of healthy lifestyle, especially for the social subgroups of elders, ethnic minorities, those with little education, single people, and unemployed people, who generally have poorer health and less participation in volunteering.

    People with disabilities in the United States experience lower levels of social integration than people without disabilities. However, less is known about the association between disability and volunteer participation-despite an extensive literature on other disparities in volunteerism. This study uses data from the 2009-2015 Volunteer Supplement of the Current Population Survey to evaluate how working-aged adults with sensory disabilities, cognitive disabilities, physical disabilities, or multiple disabilities access, participate in, and maintain volunteer roles. Net of sociodemographic characteristics, adults with disabilities are no less likely than those without disabilities to report informal volunteering, although the presence of physical and multiple disabilities negatively associates with formal volunteering. Adults with disabilities report no fewer annual hours or weeks than those without disabilities if they are formal volunteers, but the mechanism through which they initially become involved in volunteer organizations varies. People with different types of disability experience different patterns of volunteering, and the sociodemographic characteristics associated with having a disability exacerbate many of these differences. Results suggest that adults with disabilities can-and do-participate in voluntary work, but may face barriers to accessing formal volunteer roles. Copyright © 2017 Elsevier Inc. All rights reserved.

    2002-01-01

    To understand the social beliefs of volunteers in emergency feeding programs (EFPs) regarding hunger and whether volunteer experiences broadened understanding of hunger. An interpretivist paradigm and qualitative methods were used. Seventeen volunteers were recruited and interviewed from three EFPs. Interviews were analyzed using the constant comparative method. Volunteering in EFPs increased volunteers' awareness of the prevalence of hunger in their communities. More involved volunteers had a greater understanding of the life situations of the hungry. The volunteers felt that increasing self-sufficiency and private responses were appropriate solutions to hunger. The volunteers' attitudes and social beliefs were similar to those of the general public. Interventions that facilitate interaction between volunteers and clients, promote reflection on volunteer experiences, and provide alternative viewpoints on poverty are needed to broaden volunteers' understanding of hunger and food insecurity.

The aim is to analyze the current state of social and ecological consciousness of youth and consider the introduction of student volunteering activity in the formation of ecological consciousness in the context of Republic of Dagestan.Discussion. The social and environmental issues with a negative shade are largely typical for Dagestan. The consequences of these are one of the areas of social work the main goal of which is to provide assistance and support to people who are in difficult life situation. Annually, more than 150 bachelors and masters of social work graduate the Department of Sociology of Dagestan State University. Proper use of the potential of student volunteering activities, in our opinion, will help to a certain extent to solve the existing in the country social and environmental problems, reduce their negative impact on the population.Conclusion. The Republic of Dagestan is a very important region for the realization of the ideas of volunteerism. However, an analysis of the work done has shown that voluntary associations, as a rule, exist in many universities and their activities is a mere formality as they are similar to circles of interest. There is a lack of systematic and purposeful approach on the use of voluntary activities of students. We came to the conclusion that it is crucial to implement an appropriate approach, the main objectives of which shall be as follows: the organization of training aimed at the development of social activity and personal potential; formation of ecological awareness; use of volunteering activities of future social workers in dealing with social and environmental problems.

    The Internet of Things envisions a web-connected infrastructure of billions of sensors and actuation devices. However, the current state-of-the-art presents another reality: monolithic end-to-end applications tightly coupled to a limited set of sensors and actuators. Growing such applications with new devices or behaviors, or extending the existing infrastructure with new applications, involves redesign and redeployment. We instead propose a modular approach to these applications, breaking them into an equivalent set of functional units (context engines) whose input/output transformations are driven by general-purpose machine learning, demonstrating an improvement in compute redundancy and computational complexity with minimal impact on accuracy. In conjunction with formal data specifications, or ontologies, we can replace application-specific implementations with a composition of context engines that use common statistical learning to generate output, thus improving context reuse. We implement interconnected context-aware applications using our approach, extracting user context from sensors in both healthcare and grid applications. We compare our infrastructure to single-stage monolithic implementations with single-point communications between sensor nodes and the cloud servers, demonstrating a reduction in combined system energy by 22-45%, and multiplying the battery lifetime of power-constrained devices by at least 22x, with easy deployment across different architectures and devices.

    Locally requested and planned overseas volunteering in low-income and middle-income countries by National Health Service (NHS) staff can have benefits for the host or receiving nation, but its impact on the professional development of NHS staff is not proven. The Knowledge and Skills Framework (KSF) and Leadership Framework (LF) are two tools used by employers as a measure of individuals' development. We have used dimensions from both tools as a method of evaluating the benefit to NHS doctors who volunteer overseas. 88 NHS volunteers participating with local colleagues in Primary Trauma Care and orthopaedic surgical training courses in sub-Saharan Africa were asked to complete an online self-assessment questionnaire 6 months following their return to the UK. The survey consisted of questions based on qualities outlined in both the KSF and LF. 85 completed responses to the questionnaire were received. In every KSF domain assessed, the majority of volunteers agreed that their overseas volunteering experience improved their practice within the NHS. Self-assessed pre-course and post-course scores evaluating the LF also saw a universal increase, notably in the 'working with others' domain. There is a growing body of literature outlining the positive impact of overseas volunteering on NHS staff. Despite increasing evidence that such experiences can develop volunteers' essential skills, individuals often find it difficult to gain support of their employers. Our study, in line with the current literature, shows that overseas volunteering by NHS staff can provide an opportunity to enhance professional and personal development. Skills gained from volunteering within international links match many of the qualities outlined in both KSF and LF, directly contributing to volunteers' continued professional development. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To evaluate how accounting for driving status altered the relationship between volunteering and mortality in U.S. retirees. Observational prospective cohort. Nationally representative sample from the Health and Retirement Study in 2000 and 2002 followed to 2006. Retirees aged 65 and older (N=6,408). Participants self-reported their volunteering, driving status, age, sex, race or ethnicity, presence of chronic conditions, geriatric syndromes, socioeconomic factors, functional limitations, and psychosocial factors. Death by December 31, 2006, was the outcome. For drivers, mortality in volunteers (9%) and nonvolunteers (12%) was similar; for limited or non-drivers, mortality for volunteers (15%) was markedly lower than for nonvolunteers (32%). Adjusted results showed that, for drivers, the volunteering-mortality odds ratio (OR) was 0.90 (95% confidence interval (CI)=0.66-1.22), whereas for limited or nondrivers, the OR was 0.62 (95% CI=0.49-0.78) (interaction P=.05). The effect of driving status was greater for rural participants, with greater differences between rural drivers and rural limited or nondrivers (interaction P=.02) and between urban drivers and urban limited or nondrivers (interaction P=.81). The influence of volunteering in decreasing mortality seems to be stronger in rural retirees who are limited or nondrivers. This may be because rural or nondriving retirees are more likely to be socially isolated and thus receive more benefit from the greater social integration from volunteering. © 2011, Copyright the Authors.

    Full Text Available This paper presents an algorithm/architecture and Hardware/Software co-designs for implementing a digital edge computing layer on a Zynq platform in the context of the Internet of Multimedia Things (IoMT. Traditional cloud computing is no longer suitable for applications that require image processing due to cloud latency and privacy concerns. With edge computing, data are processed, analyzed, and encrypted very close to the device, which enable the ability to secure data and act rapidly on connected things. The proposed edge computing system is composed of a reconfigurable module to simultaneously compress and encrypt multiple images, along with wireless image transmission and display functionalities. A lightweight implementation of the proposed design is obtained by approximate computing of the discrete cosine transform (DCT and by using a simple chaotic generator which greatly enhances the encryption efficiency. The deployed solution includes four configurations based on HW/SW partitioning in order to handle the compromise between execution time, area, and energy consumption. It was found with the experimental setup that by moving more components to hardware execution, a timing speedup of more than nine times could be achieved with a negligible amount of energy consumption. The power efficiency was then enhanced by a ratio of 7.7 times.

    Galaxy Zoo is a citizen science website in which members of the public volunteer to classify galaxies, thereby helping astronomers conduct publishable research into galaxy morphologies and environments. Although the site was originally created to answer a few specific questions, some members of the community - both scientists and volunteers - have spontaneously developed an interest in a wider variety of questions. Volunteers have pursued answers to these questions with guidance from professional astronomers; in completing these projects, volunteers have independently used some of the same data viewing and analysis tools that professional astronomers use, and have even developed their own online tools. They have created their own research questions and their own plans for data analysis, and are planning to write scientific papers with the results to be submitted to peer-reviewed scientific journals. Volunteers have identified a number of such projects. These volunteer-initiated projects have extended the scientific reach of Galaxy Zoo, while also giving volunteers first-hand experience with the process of science. We are interested in the process by which volunteers become interested in volunteer-initiated projects, and what tasks they participate in, both initially and as their involvement increases. What motivates a volunteer to become involved in a volunteer-initiated project? How does his or her motivation change with further involvement? We are conducting a program of qualitative education research into these questions, using as data sources the posts that volunteers have made to the Galaxy Zoo forum and transcripts of interviews with volunteers.

    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. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

    Volunteer work can be a very significant form of social participation for seniors. It can also provide seniors with important physical and psychological health benefits. This explains why occupational therapists and other health care professionals, as well as community workers who are concerned with healthy aging, appeal to seniors to volunteer in health promotion and community support However, the recruitment and ongoing involvement of seniors as volunteers is often challenging. A systematic review of the literature was undertaken to enlighten practitioners working in this domain. The objective was to identify factors that influence seniors' participation in volunteer work. Six bibliographic databases were searched using key words. A total of 27 relevant papers were retrieved and allowed an identification of a series of factors that could influence seniors' participation in volunteer work, namely personal factors, environmental factors, and occupational factors. This analysis leads to practical guidelines for facilitating the recruitment and maintenance of seniors' engagement in volunteer work.

    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.

    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.

    Quantum computers can (in theory) solve certain problems far faster than a classical computer running any known classical algorithm. While existing technologies for building quantum computers are in their infancy, it is not too early to consider their scalability and reliability in the context of the design of large-scale quantum computers. To architect such systems, one must understand what it takes to design and model a balanced, fault-tolerant quantum computer architecture. The goal of this lecture is to provide architectural abstractions for the design of a quantum computer and to explore

    Volunteering among older adults has received increasing attention from researchers, policy makers, and associations. However, there remains a lack of knowledge in how volunteering is impacted by other activities in the lives of older adults. In order to understand activity engagement in later life, insights into the extent to which activities compete with or complement each other are necessary. Data for the present research were derived from the Belgian Aging Studies (N = 23,768). The main objective is to uncover the activities that impede or stimulate actual volunteering and/or the likeliness to volunteer at an older age. Structural equation models indicate a strong positive correlation between altruistic types of activities and actual volunteering. Furthermore, older adults active in personal leisure activities are more drawn to be potential volunteers. The article demonstrates that the activity level of older people is not sufficient to understand volunteering, that is, a distinction between the types of activities is essential. © The Author(s) 2015.

    It has been widely recognised that poor health is one of the main barriers to participation in volunteer activities in older age. Therefore, it is crucial to examine the participation of older people in volunteering, especially those in poor health. Based on the resource theory of volunteering, the aim of this study is to better understand the correlates of volunteering among older people with different health statuses, namely those without health problems (neither multimorbidity nor disability), those with mild health problems (multimorbidity or disability), and those with severe health problems (multimorbidity and disability). Data were drawn from the fourth wave (2011-2012, release 1.1.1) of the Survey of Health, Ageing and Retirement in Europe, which includes European people aged 50 years or older. The results showed that variables linked to volunteering were generally similar regardless of health status, but some differences were nevertheless identified. For older people with mild or severe health problems, for instance, depressive symptoms were negatively associated with their involvement in volunteer activities. We found a positive association of being widowed (rather than married) with volunteering in older people with particularly poor health, whereas high income was associated with volunteering in the case of mild health problems only. These results demonstrate that variables associated with volunteer participation partially differ between older people depending on their health status. These differences should be considered by policy makers in their attempts to promote volunteering in older people, as a means of preventing their social exclusion.

  7. The performance model of dynamic virtual organization (VO) formations within grid computing context

    2009-01-01

    Grid computing aims to enable 'resource sharing and coordinated problem solving in dynamic, multi-institutional virtual organizations (VOs)'. Within the grid computing context, successful dynamic VO formations mean a number of individuals and institutions associated with certain resources join together and form new VOs in order to effectively execute tasks within given time steps. To date, while the concept of VOs has been accepted, few research has been done on the impact of effective dynamic virtual organization formations. In this paper, we develop a performance model of dynamic VOs formation and analyze the effect of different complex organizational structures and their various statistic parameter properties on dynamic VO formations from three aspects: (1) the probability of a successful VO formation under different organizational structures and statistic parameters change, e.g. average degree; (2) the effect of task complexity on dynamic VO formations; (3) the impact of network scales on dynamic VO formations. The experimental results show that the proposed model can be used to understand the dynamic VO formation performance of the simulated organizations. The work provides a good path to understand how to effectively schedule and utilize resources based on the complex grid network and therefore improve the overall performance within grid environment.

    CernVM Co-Pilot is a framework for instantiating an ad-hoc computing infrastructure on top of distributed computing resources. Such resources include commercial computing clouds (e.g. Amazon EC2), scientific computing clouds (e.g. CERN lxcloud), as well as the machines of users participating in volunteer computing projects (e.g. BOINC). The framework consists of components that communicate using the Extensible Messaging and Presence protocol (XMPP), allowing for new components to be developed in virtually any programming language and interfaced to existing Grid and batch computing infrastructures exploited by the High Energy Physics community. Co-Pilot has been used to execute jobs for both the ALICE and ATLAS experiments at CERN. CernVM Co-Pilot is also one of the enabling technologies behind the LHC@home 2.0 volunteer computing project, which is the first such project that exploits virtual machine technology. The use of virtual machines eliminates the necessity of modifying existing applications and adapt...

    2017-12-01

    Highly neurotic persons have dispositional characteristics that tend to precipitate social anxiety that discourages formal volunteering. With the 50 American states as analytical units, Study 1 found that state resident neuroticism correlated highly ( r = -.55) with state volunteering rates and accounted for another 26.8% of the volunteering rate variance with selected state demographics controlled. Study 2 replicated Study 1 during another period and extended the association to college student, senior, secular, and religious volunteering rates. Study 3 showed state resident percentages engaged in other social behaviors involving more familiarity and fewer demands than formal volunteering related to state volunteering rates but not to neuroticism. In Study 4, state resident neuroticism largely accounted statistically for relations between state volunteering rates and state population density, collectivism, social capital, Republican preference, and well-being. This research is the first to show that state resident neuroticism is a potent predictor of state volunteering rates.

    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.

    The tremendous need for increasing the quantity and quality of global pediatric surgical care in underserved areas has been well documented. Concomitantly there has been a significant increase in interest by pediatric surgeons in helping to relieve this problem through surgical volunteerism. The intent of the article is to serve as a practical guide for pediatric surgeons contemplating or planning a short-term global volunteer endeavor. The article is based on the authors' personal experiences and on the published experiences of other volunteers. The following aspects of volunteerism are discussed: ethical considerations, where and how to go, what and whom to take with you, what to expect in your volunteer locale, and what to do and what to avoid in order to enhance the volunteer experience. The points discussed in this guide will hopefully make the volunteer activity one that results in greatly improved immediate and long term surgical care for children and improves the chances that the activity will be a meaningful, pleasant, and productive experience for both the volunteer and the host physician.

    Full Text Available Genome-wide experimental studies in Saccharomyces cerevisiae reveal that autonomous replicating sequence (ARS requires an essential consensus sequence (ACS for replication activity. Computational studies identified thousands of ACS like patterns in the genome. However, only a few hundreds of these sites act as replicating sites and the rest are considered as dormant or evolving sites. In a bid to understand the sequence makeup of replication sites, a content and context-based analysis was performed on a set of replicating ACS sequences that binds to origin-recognition complex (ORC denoted as ORC-ACS and non-replicating ACS sequences (nrACS, that are not bound by ORC. In this study, DNA properties such as base composition, correlation, sequence dependent thermodynamic and DNA structural profiles, and their positions have been considered for characterizing ORC-ACS and nrACS. Analysis reveals that ORC-ACS depict marked differences in nucleotide composition and context features in its vicinity compared to nrACS. Interestingly, an A-rich motif was also discovered in ORC-ACS sequences within its nucleosome-free region. Profound changes in the conformational features, such as DNA helical twist, inclination angle and stacking energy between ORC-ACS and nrACS were observed. Distribution of ACS motifs in the non-coding segments points to the locations of ORC-ACS which are found far away from the adjacent gene start position compared to nrACS thereby enabling an accessible environment for ORC-proteins. Our attempt is novel in considering the contextual view of ACS and its flanking region along with nucleosome positioning in the S. cerevisiae genome and may be useful for any computational prediction scheme.

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.

    To examine whether psychosocial factors that can be a target for interventions, such as volunteering, are associated with risk of cognitive impairment. Health and Retirement Study (HRS) data from 1998 to 2012, a nationally representative longitudinal panel survey of older adults assessed every 2 years, were used. The HRS interviews participants aged 50 and older across the contiguous United States. Individuals aged 60 and older in 1998 (N = 13,262). Personal interviews were conducted with respondents to assess presence of cognitive impairment, measured using a composite across cognitive measures. Volunteering at the initial assessment and volunteering regularly over time independently decreased the risk of cognitive impairment over 14 years, and these findings were maintained independent of known risk factors for cognitive impairment. Greater risk of onset of cognitive impairment was associated with being older, being female, being nonwhite, having fewer years of education, and reporting more depressive symptoms. Consistent civic engagement in old age is associated with lower risk of cognitive impairment and provides impetus for interventions to protect against the onset of cognitive impairment. Given the increasing number of baby boomers entering old age, the findings support the public health benefits of volunteering and the potential role of geriatricians, who can promote volunteering by incorporating "prescriptions to volunteer" into their patient care. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    2012-12-01

    Driven by socioemotional selectivity theory, this study examined whether age moderated the associations of volunteering motives with physical and psychological well-being in a sample of Hong Kong Chinese volunteers. Volunteering motives were measured by the volunteer functions inventory. Findings revealed that even after controlling for demographic characteristics and volunteering experience, age was related to higher social and value motives but lower career motives, and moderated the associations of social and protective motives with well-being. The associations of social motives with physical well-being were positive among older volunteers, but were negative among younger- and middle-aged volunteers. While protective motives were positively related to psychological well-being among all the volunteers, such effects were stronger among younger- and middle-aged volunteers than among older volunteers. Findings highlight the role of age in determining the relationship between volunteering motives and well-being.

    Two experiments re-examined whether chewing spearmint gum affects initial word learning and/or immediate recall for a word list. Both experiments failed to show effects of chewing gum at learning or recall, nor did they suggest that chewing gum produces a context-dependent memory effect. This was true when extraneous contextual cues at learning and recall were minimised (Experiment 2). Together, the data are inconsistent with [Wilkinson, L., Scholey, A. & Wesnes, K. (2002). Chewing gum selectively improves aspects of memory in healthy volunteers. Appetite, 38, 235-236.] claim that chewing gum aids immediate recall of visually presented words. Our results are consistent with [Baker, J. R., Bezance, J. B., Zellaby, E. & Aggleton, J. P. (2004). Chewing gum can produce context-dependent effects upon memory. Appetite, 43, 207-210.] finding that chewing gum of itself is not a sufficient condition to provoke context-dependent learning with immediate testing.

    This article examines the individual economic returns to volunteering during different stages of working life. The article uses a unique panel dataset created by combining rich survey data from Denmark with information on wages from administrative registers covering the period from 2004 to 2012....... Applying a two-way fixed effects regression model that controls for both period-specific and individual-specific effects, the article finds that for labour market entrants and for people in the early stages of their working life, an additional year of volunteer work experience yields a significant positive...... return. However, the economic returns to volunteer work experience decrease as a function of professional labour market experience. For people with more than six years of professional labour market experience, the economic returns to volunteer work experience are insignificant. On these grounds...

    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.

    Sustained engagement in volunteering and its correlates have been examined in many studies across the globe. However, there is a dearth of research that explores the perspectives of long-term formal volunteers on the nature of changes perceived in oneself as a result of volunteering. Moreover, the linkages between psychological well-being and volunteering have been insufficiently explored. The present study was aimed at addressing these gaps. A heterogeneous sample of 20 long-term formal volunteer engaged in volunteering across different voluntary organisations in a southern metropolitan Indian city formed the primary sample for the study. In addition, a group of 21 short-term volunteers, matched on age, income and gender, was utilised for comparison with long-term volunteers on well-being indices. A semi structured interview schedule was used to explore self-perceived changes attributable to volunteering experience. In addition, a few standardised measures were used to comprehensively assess subjective well-being and psychological well-being. The interview data provided rich descriptions of perceived positive changes in self across cognitive, behavioral and emotional domains. Mirroring these patterns, the quantitative analyses indicated that long-term volunteers experienced higher levels of psychological well-being (sense of mastery and competence, self-acceptance and sense of engagement and growth) than short-term volunteers. The potential mechanisms involved in beneficial outcomes of long-term volunteering and implications for further research are highlighted.

  16. Volunteering in the care of people with severe mental illness: a systematic review.

    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. 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. 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. 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 backgrounds. The act of volunteering can not only benefit people with SMI, but also the volunteers

    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.

  18. Volunteering predicts health among those who value others: two national studies.

    Poulin, Michael J

    2014-02-01

    The purpose of these studies was to examine the role of positive views of other people in predicting stress-buffering effects of volunteering on mortality and psychological distress. In Study 1, stressful life events, volunteering, and hostile cynicism assessed in a baseline Detroit-area survey (N = 846) predicted survival over a 5-year period, adjusting for relevant covariates. In Study 2, stressful life events, volunteering, and world benevolence beliefs assessed in a baseline national survey (N = 1,157) predicted psychological distress over a 1-year period, adjusting for distress at baseline. In Study 1, a Cox proportional hazard model indicated that for individuals low in cynicism, stress predicted mortality at low levels of volunteering but not at high levels of volunteering. This effect was not present among those high in cynicism. In Study 2, multiple regression analysis revealed that among individuals high in world benevolence beliefs, stress predicted elevated distress at low levels of volunteering but not at high levels of volunteering. This effect was absent for those lower in world benevolence beliefs. Consistent with prior research on helping behavior, these studies indicate that helping behavior can buffer the effects of stress on health. However, the results of these studies indicate that stress-buffering effects of volunteering are limited to individuals with positive views of other people. Not all individuals may benefit from volunteering, and health-promotion efforts seeking to draw on health benefits of helping behavior may need to target their approach accordingly.

  19. An exploratory study of early letter-sound knowledge in a low socio-economic context in South Africa

    2011-05-01

    Full Text Available This paper explores one aspect of early literacy development in a low socio-economic context in South Africa. Assessments conducted with a sample of children from two disadvantaged communities in Cape Town indicated that in this context, almost half of the learners entering Grade One were unable to recognise any letters. A Grade R intervention conducted by volunteers showed that children from this context were able to learn letter-sounds in Grade R through a programme that focused on teaching letter-sounds in the context of building language skills, emergent writing and concepts about print. In order to strengthen the effectiveness of the intervention, the volunteer programme was supplemented by support for the Grade R teacher and teaching assistant. Follow-up assessments of one of the intervention groups at the end of Grade One revealed significant correlations between early Grade One letter knowledge and end of Grade One word reading and spelling skills. The findings of this exploratory study are in line with research that shows the importance of letter-sound knowledge in the earliest stages of learning to read. This raises concerns about the historical lack of emphasis in the Grade R curriculum on this aspect of early literacy development. Although the study has a narrow focus and conclusions cannot be drawn about other aspects of early literacy learning in this context, the results suggest an urgent need for quality Grade R teacher training programmes with a specific focus on emergent literacy.

    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.

    Research on outcomes of volunteering in later life largely focuses on the health of volunteers. This is in contrast to studies of youth, where attention is directed toward the effects of volunteering on subsequent productive and citizen behaviors. In this study, we examined the effects of volunteering on subsequent social and civic activity of older adults. This study was conducted with volunteers from Experience Corps® (EC), a national program that brings older adults into schools to work with students. Data were derived from a baseline survey of older adults who were new EC volunteers in fall of 2006 and 2007. Follow-up interviews were conducted with 338 volunteers in fall 2010 to capture work, education, and community activities undertaken subsequent to joining EC. Subsequent to joining EC, 16% of volunteers reported that they started a new job, 53% started another volunteer position, 40% started a community activity, and 39% took a class/started educational program. When asked if and how EC participation played a role in their new involvements, 71% said it increased confidence, 76% said it increased realization of the importance of organized activities/daily structure, and more than 40% said they made social connections that led to new involvements. Most reported they were more likely to be involved in advocacy efforts for public education. Volunteering among older adults is a means as well as an end--just as it is for young people. Programs can do more to attract and serve older adults by promoting volunteering as a pathway to other engagements, including work, social, and civic activities. © 2014 Society for Public Health Education.

    In Europe, volunteers have an important role in the delivery of palliative care. As part of the EU co-funded Europall project, 4 aspects of volunteering in palliative care were studied for 7 European countries (Belgium, England, France, Germany, the Netherlands, Poland, and Spain). These included (1) involvement of volunteers in palliative care, (2) organization of palliative care volunteering, (3) legal regulations concerning volunteering, and (4) education and training of palliative care volunteering. A literature search combined with an interview study. Information from the scientific literature, and country-specific policy documents were obtained and completed, along with data of consecutive semi-structured interviews with experts in the field of palliative care in the participating countries. In all countries, volunteers appeared to be involved in palliative care, yet their involvement across health care settings differed per country. England, for example, has the highest number of volunteers whereas Spain has the lowest number. Volunteering is embedded in law and regulations in all participating countries except for England and the Netherlands. In all participating countries, training programs are available and volunteers are organized, both on a national and a regional level. This study provides a descriptive overview of volunteer work in palliative care in 7 European countries, with a focus on the organizational aspects. Further research should concentrate on the roles and responsibilities of volunteers in the care for the terminally ill in different European health systems. © 2014 World Institute of Pain.

    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.

    2006-01-01

    While diverse studies carried out in nursing and medical personnel have demonstrated that health workers can be subject to burnout, little effort has been focused on investigating burnout in volunteer hospital workers. The aim of the present study was to verify if burnout exists with volunteer auxiliary personnel and investigate what organizational conditions may favour it. The study was carried out on 80 volunteer workers of the Red Cross of Mortara (PV), subdivided into two categories: those performing emergency interventions and those performing routine services. For the evaluation of burnout, the Italian version of the Maslach Burnout Inventory was used, together with a qualitative type of methodology. A 5-factor multivariate analysis (sex x shift x team x seniority x role), having as dependent variables the three scales of the MBI, showed that the highest values of depersonalization and fulfillment are found in the emergency team, and that subjects with least seniority are those who are least satisfied or fulfilled. The category of team-leader resulted as that with the highest values of emotional burnout, while sex- and shift-based differences were restricted to routine service workers. Despite these differences, findings showed that subjects are minimally affected by problems linked to burnout, although some relational and organizational difficulties emerged with the medical staff that underlie a certain degree of professional dissatisfaction.

    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.

    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

    This study investigated whether volunteering was related to 5 risk factors for cardiovascular disease (CVD) and the metabolic syndrome (MetS) among middle-aged and older adults. Data from the 2004 and 2006 waves of the Health and Retirement Study (N = 7,803) were examined. Logistic regression was used to describe the relationships among volunteering and central adiposity, hypertension, lipid dysregulation, elevated blood glucose levels, and high inflammation, along with 2 indexes of the MetS. Among middle-aged adults, results showed that volunteers were less likely to have high central adiposity, lipid dysregulation, elevated blood glucose levels, and MetS compared with non-volunteers. For older adults, results showed volunteers were less likely to be hypertensive and more likely to have lipid dysregulation than their non-volunteer counterparts. These results supported findings from other studies that formal volunteering is beneficial for middle-aged adults, and to a lesser degree, older adults. Further research is required to determine what factors may mediate the volunteer-CVD risk relationships. © The Author 2015.

    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. PMID:25843985

    A compassionate community approach to palliative care provides important rationale for building community-based hospice volunteer capacity. In this project, we piloted one such capacity-building model in which volunteers and a nurse partnered to provide navigation support beginning in the early palliative phase for adults living in community. The goal was to improve quality of life by developing independence, engagement, and community connections. Volunteers received navigation training through a three-day workshop and then conducted in-home visits with clients living with advanced chronic illness over one year. A nurse navigator provided education and mentorship. Mixed method evaluation data was collected from clients, volunteer navigators, the nurse navigator, and other stakeholders. Seven volunteers were partnered with 18 clients. Over the one-year pilot, the volunteer navigators conducted visits in home or by phone every two to three weeks. Volunteers were skilled and resourceful in building connections and facilitating engagement. Although it took time to learn the navigator role, volunteers felt well-prepared and found the role satisfying and meaningful. Clients and family rated the service as highly important to their care because of how the volunteer helped to make the difficult experiences of aging and advanced chronic illness more livable. Significant benefits cited by clients were making good decisions for both now and in the future; having a surrogate social safety net; supporting engagement with life; and ultimately, transforming the experience of living with illness. Overall the program was perceived to be well-designed by stakeholders and meeting an important need in the community. Sustainability, however, was a concern expressed by both clients and volunteers. Volunteers providing supportive navigation services during the early phase of palliative care is a feasible way to foster a compassionate community approach to care for an aging population

    1.5 million Kenyans are living with HIV/AIDS as per 2015 estimates. Though there is a notable decline in new HIV infections, continued effort is still needed to develop an efficacious, accessible and affordable HIV vaccine. HIV vaccine clinical trials bear risks, hence a need to understand volunteer motivators for enrolment, retention and follow-up. Understanding the factors that motivate volunteers to participate in a clinical trial can help to strategize, refine targeting and thus increase enrolment of volunteers in future HIV vaccine clinical trials. The health belief model classifies motivators into social benefits such as 'advancing research' and collaboration with science, and personal benefits such as health benefits and financial interests. A thematic analysis was carried out on data obtained from four HIV clinical trials conducted at KAVI-Institute of Clinical Research in Nairobi Kenya from 2009 to 2015. Responses were obtained from a Questionnaire administered to the volunteers during their screening visit at the research site. Of the 281 healthy, HIV-uninfected volunteers participating in this study; 38% were motivated by personal benefits including, 31% motivated by health benefits and 7% motivated by possible financial gains. In addition, 62% of the volunteers were motivated by social benefits with 20% of who were seeking to help their family/society/world while 42% were interested in advancing research. The majority of volunteers in the HIV vaccine trials at our site were motivated by social benefits, suggesting that altruism can be a major contributor to participation in HIV vaccine studies. Personal benefits were a secondary motivator for the volunteers. The motivators to volunteer in HIV clinical trials were similar across ages, education level and gender. Education on what is needed (including volunteer participation) to develop an efficacious vaccine could be the key to greater volunteer motivation to participate in HIV vaccine clinical trials.

    Organizational volunteering has been touted as an effective strategy for older adults to help themselves while helping others. Extending previous reviews, we carried out a meta-analysis of the relation between organizational volunteering by late-middle-aged and older adults (minimum age = 55 years old) and risk of mortality. We focused on unadjusted effect sizes (i.e., bivariate relations), adjusted effect sizes (i.e., controlling for other variables such as health), and interaction effect sizes (e.g., the joint effect of volunteering and religiosity). For unadjusted effect sizes, on average, volunteering reduced mortality risk by 47%, with a 95% confidence interval ranging from 38% to 55%. For adjusted effect sizes, on average, volunteering reduced mortality risk by 24%, with a 95% confidence interval ranging from 16% to 31%. For interaction effect sizes, we found preliminary support that as public religiosity increases, the inverse relation between volunteering and mortality risk becomes stronger. The discussion identifies several unresolved issues and directions for future research. PsycINFO Database Record (c) 2013 APA, all rights reserved.

  7. International clinical volunteering in Tanzania: A postcolonial analysis of a Global Health business.

    2018-03-01

    This article traces how scarcities characteristic of health systems in low-income countries (LICs), and increasing popular interest in Global Health, have inadvertently contributed to the popularisation of a specific Global Health business: international clinical volunteering through private volunteer placement organisations (VPOs). VPOs market neglected health facilities as sites where foreigners can 'make a difference', regardless of their skill set. Drawing on online investigation and ethnographic research in Tanzania over four field seasons from 2011 to 2015, including qualitative interviews with 41 foreign volunteers and 90 Tanzanian health workers, this article offers a postcolonial analysis of VPO marketing and volunteer action in health facilities of LICs. Two prevalent postcolonial racialised tropes inform both VPO marketing and foreign volunteers' discourses and practices in Tanzania. The first trope discounts Tanzanian expertise in order to envision volunteers in expert roles despite lacking training, expertise, or contextual knowledge. The second trope envisions Tanzanian patients as so impoverished that insufficiently trained volunteer help is 'better than nothing at all'. These two postcolonial racialised tropes inform the conceptual work undertaken by VPO marketing schemes and foreign volunteers in order to remake Tanzanian health professionals and patients into appropriate and justifiable sites for foreign volunteer intervention.

    Full Text Available This paper focuses on volunteer tourism as a sustainable form of tourism relating to the volunteer service at a tourism destination and specific tourism activities. The aim of the paper is to explore volunteer tourism in Slovakia with examples of organized events, especially to search exactly how event’s organizers support the development of domestic and inbound volunteer tourism in Slovakia. This paper is based on a sociological survey. We addressed 653 heterogeneous event’s organizers in Slovakia. 18% of them participated in the questionnaire survey. The collected data were processed by selected mathematical and statistical methods in SPSS statistics program. As such, we found most events organizers team up with volunteers. Only half of the organizers cooperate with local volunteers, while the second half also support the development of volunteer tourism engaging in voluntourism. In the case of attractive events, the engagement of voluntourists could be more effective. The current situation has resulted from missing information about the management of volunteers but it could be improved through an e-manual for event organizers providing an outline guide for volunteer management.

    Research reveals that older people do a significant amount of volunteer work. Moreover, a good deal of this volunteering takes place in religious institutions. The purpose of this study is to examine how social factors in the church influence the decision to volunteer. The analyses are conducted in two steps. First, data from a longitudinal nationwide survey of older people are used to show that increases in spiritual support (i.e., assistance from fellow church members that is designed to bolster religious beliefs and behaviors) are associated with increases in the frequency of volunteer work. Second, cross-sectional analyses from the same survey suggest that spiritual support is associated with volunteering in part because it promotes greater compassion. However, the magnitude of the relationship between compassion and volunteering is fairly modest. © The Author(s) 2014.

    The Portal for Families Overcoming Neurodevelopmental Disorders (PFOND) provides a structured Internet interface for the sharing of information with individuals struggling with the consequences of rare developmental disorders. Large disease-impacted communities can support fundraising organizations that disseminate Web-based information through elegant websites run by professional staff. Such quality resources for families challenged by rare disorders are infrequently produced and, when available, are often dependent upon the continued efforts of a single individual. The project endeavors to create an intuitive Web-based software system that allows a volunteer with limited technical computer skills to produce a useful rare disease website in a short time period. Such a system should provide access to emerging news and research findings, facilitate community participation, present summary information about the disorder, and allow for transient management by volunteers who are likely to change periodically. The prototype portal was implemented using the WordPress software system with both existing and customized supplementary plug-in software modules. Gamification scoring features were implemented in a module, allowing editors to measure progress. The system was installed on a Linux-based computer server, accessible across the Internet through standard Web browsers. A prototype PFOND system was implemented and tested. The prototype system features a structured organization with distinct partitions for background information, recent publications, and community discussions. The software design allows volunteer editors to create a themed website, implement a limited set of topic pages, and connect the software to dynamic RSS feeds providing information about recent news or advances. The prototype was assessed by a fraction of the disease sites developed (8 out of 27), including Aarskog-Scott syndrome, Aniridia, Adams-Oliver syndrome, Cat Eye syndrome, Kabuki syndrome

  16. The importance of context: When relative relief renders pain pleasant

    Leknes, Siri; Berna, Chantal; Lee, Michael C.; Snyder, Gregory D.; Biele, Guido; Tracey, Irene

    2013-01-01

    Context can influence the experience of any event. For instance, the thought that “it could be worse” can improve feelings towards a present misfortune. In this study we measured hedonic feelings, skin conductance, and brain activation patterns in 16 healthy volunteers who experienced moderate pain in two different contexts. In the “relative relief context,” moderate pain represented the best outcome, since the alternative outcome was intense pain. However, in the control context, moderate pain represented the worst outcome and elicited negative hedonic feelings. The context manipulation resulted in a “hedonic flip,” such that moderate pain elicited positive hedonics in the relative relief context. Somewhat surprisingly, moderate pain was even rated as pleasant in this context, despite being reported as painful in the control context. This “hedonic flip” was corroborated by physiological and functional neuroimaging data. When moderate pain was perceived as pleasant, skin conductance and activity in insula and dorsal anterior cingulate were significantly attenuated relative to the control moderate stimulus. “Pleasant pain” also increased activity in reward and valuation circuitry, including the medial orbitofrontal and ventromedial prefrontal cortices. Furthermore, the change in outcome hedonics correlated with activity in the periacqueductal grey (PAG) of the descending pain modulatory system (DPMS). The context manipulation also significantly increased functional connectivity between reward circuitry and the PAG, consistent with a functional change of the DPMS due to the altered motivational state. The findings of this study point to a role for brainstem and reward circuitry in a context-induced “hedonic flip” of pain. PMID:23352758

    The Volunteering-in-Place (VIP) Program was developed to provide individualized meaningful volunteer activities matched to interests and capabilities for older adults with MCI in assisted living. The purposes of this single-site pre-test/post-test pilot study were to (1) establish feasibility of the VIP Program based on treatment fidelity (design, treatment, delivery, enactment); and (2) evaluate preliminary efficacy via improvement in psychological health (depressive symptoms, usefulness, purpose, resilience, and life satisfaction) and decreased sedentary activity (survey and Fitbit) at 3 and 6 months. Ten residents participated. The majority was white, female and educated, and on average 88 years old. The VIP Program was feasible and most participants continued to volunteer at 6 months. There were non-significant improvements in depressive symptoms, usefulness, purpose, resilience and recreational physical activity. The results of this study provide support for the feasibility of the VIP Program. Further study is necessary to examine efficacy. Copyright © 2016 Elsevier Inc. All rights reserved.

    Although observational and experimental studies have shown that volunteering is linked with better mental health, physical health, and health behaviors, no studies have examined whether volunteering is associated with patterns of health care use. The purpose of this study was to prospectively examine whether volunteering was associated with a greater use of preventive health care services, but fewer doctor visits and nights spent in the hospital. Participants (n = 7168) were drawn from the 2006 wave of the Health and Retirement Study, a nationally representative panel study of American adults over the age of 51, and tracked for one wave (2 years). Logistic regression and generalized linear models were used for analyses. In analyses that adjusted for sociodemographic factors and baseline health, volunteers were 30% more likely to receive flu shots (OR = 1.30, 95% CI = 1.16-1.47), 47% more likely to receive cholesterol tests (OR = 1.47, 95% CI = 1.24-1.74); female volunteers were 53% more likely to receive mammograms/x-rays (OR = 1.53, 95% CI = 1.28-1.83) and 21% more likely to receive Pap smears (OR = 1.21, 95% CI = 1.03-1.41); male volunteers were 59% more likely to receive prostate exams (OR = 1.59, 95% CI = 1.29-1.95). In a model that adjusted for sociodemographic factors, volunteers spent 38% fewer nights in the hospital (RR = 0.62, 95% CI = 0.52-0.76), however volunteering was not associated with frequency of doctor visits (RR = 0.94, 95% CI = 0.87-1.02). The association between volunteering and number of nights spent in the hospital was minimally affected after adjusting for potential confounding (baseline health) and explanatory variables (health behaviors, social integration, stress, positive psychological factors, personality). This is the first known study to examine the association between volunteering and health care use. If future studies replicate these findings, the results may be used to inform the development of new

  1. Is There a Place for Humor in Hospice Palliative Care? Volunteers Say "Yes"!

    Claxton-Oldfield, Stephen; Bhatt, Anamika

    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.

    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.

    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

    This study focused on the role of volunteer work for daily recovery from work. In a 1-week diary study with 166 employees, we assessed the amount of time spent on volunteer work during leisure time, and the recovery facets of psychological detachment from work (i.e., mentally switching off from work), mastery experiences (i.e., pursuing challenging activities), and community experiences (i.e., cultivating relationships) every day before participants went to bed. Results from hierarchical linear modeling (n = 529 days) showed volunteer work during leisure time to be positively related to mastery experiences and community experiences suggesting volunteer work to contribute to successful recovery by creating new resources.

  9. Context reinstatement and memory for intrinsic versus extrinsic context: the role of item generation at encoding or retrieval.

    Nieznański, Marek

    2014-10-01

    According to many theoretical accounts, reinstating study context at the time of test creates optimal circumstances for item retrieval. The role of context reinstatement was tested in reference to context memory in several experiments. On the encoding phase, participants were presented with words printed in two different font colors (intrinsic context) or two different sides of the computer screen (extrinsic context). At test, the context was reinstated or changed and participants were asked to recognize words and recollect their study context. Moreover, a read-generate manipulation was introduced at encoding and retrieval, which was intended to influence the relative salience of item and context information. The results showed that context reinstatement had no effect on memory for extrinsic context but affected memory for intrinsic context when the item was generated at encoding and read at test. These results supported the hypothesis that context information is reconstructed at retrieval only when context was poorly encoded at study. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    SPECT scanning using (99)Tc-TRODAT-1, a ligand that binds to dopamine transporters, may be useful for detection of early Parkinson's disease (PD), diagnosis of presymptomatic individuals, and monitoring disease progression. Understanding whether genetic factors contribute to inter-individual variability is crucial for interpreting imaging results in the context of disease pathophysiology. We tested whether polymorphisms in the genes for catechol-O-methyltransferase (COMT), monoamine-oxidase B (MAO-B), and the dopamine transporter (DAT) influence dopamine uptake parameters in the striatum in vivo in asymptomatic volunteers and patients with PD as measured with (99)Tc-TRODAT-1. (99)Tc-TRODAT-1 binding declined with age in both asymptomatic volunteers and PD patients, and depended on disease duration in PD patients. We found no significant association between COMT, MAO-B, and DAT polymorphisms and results of (99)Tc-TRODAT-1 testing in asymptomatic volunteers or patients with PD. In PD patients, the age of disease onset and speed of progression did not differ based on these polymorphisms. These results demonstrate that these specific genetic variations do not alter the fidelity of (99)Tc-TRODAT-1 as a measure of dopaminergic function in asymptomatic volunteer individuals or patients with PD.

    2009-01-01

    Background: Magnetic resonance elastography (MRE) is a recently developed imaging technique that can directly visualize and quantitatively measure tissue elasticity. Purpose: To evaluate the safety of brain MRE on human subjects. Material and Methods: The study included 20 healthy volunteers. MRE sequence scan (drive signal not applied to external force actuator) and MRE study were separately performed on each volunteer at an interval of more than 24 hours. The heart rate and blood pressure of each volunteer were measured immediately before and after MRE sequence scan and MRE study. Electroencephalography (EEG) was also performed within 2 hours after each scan. The volunteers were asked about their experience of the two scans. Randomized-block analysis of variance (ANOVA) was used to analyze the data of blood pressure and heart rate. Paired t test was used to analyze the data of the two EEG examinations. The volunteers were followed up 1 week after the examination. Results: All procedures were performed on each volunteer, and no one complained of obvious discomfort. No related adverse events were reported during follow-up. There was no statistically significant difference in heart rate or blood pressure. There was a statistically significant difference (P<0.05) in EEG results in the right temporoparietal region. Increased power was found in the theta, delta, alpha, and beta2 bands. No brain injury was detected by the EEG examinations. Conclusion: Based on the study results, brain MRE examinations are safe to perform on human subjects

    Full Text Available Objective: To evaluate the effects of botropase on various clotting factors in human volunteers. Materials and Methods: It was a prospective open label study conducted on human healthy volunteers. After the baseline screening, subjects fulfilling inclusion criteria were enrolled. On the study day, 1 ml of botropase was administered intravenously and after an hour same dose of botropase (1 ml was given by intramuscular (IM route. The efficacy and safety parameters were monitored up to 72 h from the time of intravenous (IV administration. Results: A total of 15 volunteers, belonging to 24-35 years of age were included in the study. Botropase significantly reduced the plasma level of fibrinogen and fibrin degradation products after 5 min of IV administration (P < 0.05. In addition, factor X was observed to reduce constantly by botropase administration suggesting enhanced turnover between 5 and 20 min of IV administration. Although botropase reduced clotting and bleeding time in all the volunteers, the data remains to be statistically insignificant. Conclusion: Present study demonstrated the safety and efficacy of botropase in human healthy volunteers. The study has shown that it is a factor X activator and reduces effectively clotting and bleeding time.

    We summarize methods and plans to monitor and calibrate photometric observations with our autonomous, robotic network of 2m, 1m and 40cm telescopes. These are sited globally to optimize our ability to observe time-variable sources. Wide field "context" cameras are aligned with our network telescopes and cycle every ˜2 minutes through BVr'i'z' filters, spanning our optical range. We measure instantaneous zero-point offsets and transparency (throughput) against calibrators in the 5-12m range from the all-sky Tycho2 catalog, and periodically against primary standards. Similar measurements are made for all our science images, with typical fields of view of ˜0.5 degrees. These are matched against Landolt, Stetson and Sloan standards, and against calibrators in the 10-17m range from the all-sky APASS catalog. Such measurements provide pretty good instantaneous flux calibration, often to better than 5%, even in cloudy conditions. Zero-point and transparency measurements can be used to characterize, monitor and inter-compare sites and equipment. When accurate calibrations of Target against Standard fields are required, monitoring measurements can be used to select truly photometric periods when accurate calibrations can be automatically scheduled and performed.

    This study examined whether an online course would lead to increased knowledge about the medical issues volunteers encounter during a marathon. Health care professionals who volunteered to provide medical coverage for an annual marathon were eligible for the study. Demographic information about medical volunteers including profession, specialty, education level and number of marathons they had volunteered for was collected. A 15-question test about the most commonly encountered medical issues was created by the authors and administered before and after the volunteers took the online educational course and compared to a pilot study the previous year. Seventy-four subjects completed the pre-test. Those who participated in the pilot study last year (N = 15) had pre-test scores that were an average of 2.4 points higher than those who did not (mean ranks: pilot study = 51.6 vs. non-pilot = 33.9, p = 0.004). Of the 74 subjects who completed the pre-test, 54 also completed the post-test. The overall post-pre mean score difference was 3.8 ± 2.7 (t = 10.5 df = 53 p online education demonstrated a long-term (one-year) increase in test scores. Testing also continued to show short-term improvement in post-course test scores, compared to pre-course test scores. In general, marathon medical volunteers who had no volunteer experience demonstrated greater improvement than those who had prior volunteer experience.

    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 total of 22 family members, whose deceased loved ones had used the services of a hospice palliative care volunteer, responded to a brief survey designed to assess the importance of the different kinds of support offered to them (family members) by the volunteer, their impressions of the volunteers' personal qualities/characteristics, their general experiences with the volunteer, and their overall satisfaction with the volunteer services. The kind of support that received the highest importance rating from family members was the opportunity to take a much-needed break from the demands of caring for their loved one, closely followed by emotional support, the volunteer spending time with them, and the volunteer providing them with information. Family members rated volunteers highly on a list of qualities/characteristics that exemplify individuals who are effective in this role. In all, 85% of the family members felt that their volunteer was well trained and 95% did not feel that their or their loved one's privacy had been invaded by having a volunteer. Overall, family members were very satisfied with the volunteer support they received. Some limitations of the study are discussed.

    This study examined social capital development in three all-terrain vehicles (ATV) clubs in Maine using an adapted version of Lin's (2001) social capital theory model. The structural components of social capital identified included collective assets and individual assets in the form of normative behavior and trust relationships. Also identified were counter-norms for individual ATV riders identified as having divergent norms from club members. The second component of social capital is access to and mobilization of network contacts and resources. Access networks in the context of the ATV clubs studied were identified as community and landowner relations while mobilization of resources was existent in club membership attempts toward self-governance and efforts of the statewide "umbrella" organization. Instrumental outcomes benefit society and expressive outcomes benefit the individual. Both types of returns are present in the data suggesting that ATV clubs are creating social capital. This is important information to clubs who desire to market themselves, improve their reputations, and enhance their volunteer association. It is of further interest to state governments who fund clubs through trail grants as proof that a return on investment is being realized. Theoretical and applied implications for these and other types of recreation-based volunteer associations (e.g., clubs, friends groups, advocacy groups) are presented.

    2017-08-01

    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.

    Directory of Open Access Journals (Sweden)

    Roy Cox

    Full Text Available Contextual cues are known to benefit memory retrieval, but whether and how sleep affects this context effect remains unresolved. We manipulated contextual congruence during memory retrieval in human volunteers across 12 h and 24 h intervals beginning with either sleep or wakefulness. Our data suggest that whereas contextual cues lose their potency with time, sleep does not modulate this process. Furthermore, our results are consistent with the idea that sleep's beneficial effect on memory retention depends on the amount of waking time that has passed between encoding and sleep onset. The findings are discussed in the framework of competitive consolidation theory.

    Full Text Available O trabalho voluntário é a força das organizações da sociedade civil. Existem diferenças entre o trabalho voluntário e o formal, como a remuneração e o tempo destinado ao desempenho das atividades. Ao contrário de trabalhadores formais, voluntários não recebem pagamento para o desempenho de funções. Logo, teorias motivacionais desenvolvidas numa perspectiva de trabalho formal não devem ser aplicadas a este grupo. Esse estudo identificou motivações apresentadas pelos candidatos a voluntários e atuais voluntários da Fundação Cidade Viva em João Pessoa. Quanto aos resultados, verifica-se predominância do perfil altruísta em ambas as fases utilizadas do modelo. Ainda, o perfil egoísta, foi o menos apresentado pelos respondentes da pesquisa. Outros resultados, relativos ao desligamento da atividade voluntária na Fundação, foram bastante inconclusivos.

    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.

    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.

    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.

    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.

    The Partners Clinical Process Improvement Leadership Program provides quality improvement training for clinicians and administrators, utilizing graduates as volunteer peer coaches for mentorship. We sought to understand the factors associated with volunteer coach participation and gain insight into how to improve and sustain this program. Review of coach characteristics from course database and survey of frequent coaches. Out of 516 Partners Clinical Process Improvement Leadership Program graduates from March 2010 to June 2015, 117 (23%) individuals volunteered as coaches. Sixty-one (52%) individuals coached once, 31 (27%) coached twice, and 25 (21%) coached 3 or more times. There were statistically significant associations between coaching and occupation (P = .005), Partners Clinical Process Improvement Leadership Program course taken (P = .001), and course location (P = .007). Administrators were more likely to coach than physicians (odds ratio: 1.75, P = .04). Reasons for volunteering as a coach included further development of skills, desire to stay involved with program, and enjoying mentoring. Reasons for repeated coaching included maintaining quality improvement skills, expanding skills to a wider variety of projects, and networking. A peer graduate volunteer coach model is a viable strategy for interprofessional quality improvement mentorship. Strategies that support repeat coaching and engage clinicians should be promoted to ensure an experienced and diversified group of coaches.

  2. A cortical edge-integration model of object-based lightness computation that explains effects of spatial context and individual differences

    2014-01-01

    Previous work has demonstrated that perceived surface reflectance (lightness) can be modeled in simple contexts in a quantitatively exact way by assuming that the visual system first extracts information about local, directed steps in log luminance, then spatially integrates these steps along paths through the image to compute lightness (Rudd and Zemach, 2004, 2005, 2007). This method of computing lightness is called edge integration. Recent evidence (Rudd, 2013) suggests that human vision employs a default strategy to integrate luminance steps only along paths from a common background region to the targets whose lightness is computed. This implies a role for gestalt grouping in edge-based lightness computation. Rudd (2010) further showed the perceptual weights applied to edges in lightness computation can be influenced by the observer's interpretation of luminance steps as resulting from either spatial variation in surface reflectance or illumination. This implies a role for top-down factors in any edge-based model of lightness (Rudd and Zemach, 2005). Here, I show how the separate influences of grouping and attention on lightness can be modeled in tandem by a cortical mechanism that first employs top-down signals to spatially select regions of interest for lightness computation. An object-based network computation, involving neurons that code for border-ownership, then automatically sets the neural gains applied to edge signals surviving the earlier spatial selection stage. Only the borders that survive both processing stages are spatially integrated to compute lightness. The model assumptions are consistent with those of the cortical lightness model presented earlier by Rudd (2010, 2013), and with neurophysiological data indicating extraction of local edge information in V1, network computations to establish figure-ground relations and border ownership in V2, and edge integration to encode lightness and darkness signals in V4.

    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.

    An abundance of research shows the benefits of participation in volunteer work for individuals, employers and the society as a whole. However, relatively little is known about the precursors of volunteer work. In this study, we aim to fill this gap by investigating to what extent work-related well-being can function as a driver of volunteer work. Moreover, building on the Conservations of Resources Theory (Hobfoll,), we propose that the relationship between work-related well-being (burnout an...

    Defacography is a technique of examining the rectum and anal canal by using fluoroscopy during detection. This study was done to determine the range of normal findings of defecography in young asymptomatic Korean volunteers. Twenty nine asymptomatic young volunteers underwent defecography. Anorectal angle, perineal descent, length and width of anal, rectocele, rectal intussusception and incontinence were evaluated. The range of anorectal angle was 82 .deg- 149 .deg in resting state, compared to the 63 .deg-116 .deg in squeezing state, and 95 .deg- 116 .deg in straining state respectively. The pelvic floor in straining state descended on average of 1.62 cm from the inferior margin of ischial tuberosity that its broad range of position from-5.2 cm to 0.8 cm implies a wide variation of anorectal angle and perineal descent. Mild degree of rectocele with less than 2 cm of depth was found in 12 out of 29 cases. Rectal intussusception was noted in six and rectal incontinence was seen in one case. Formation of rectocele and intussusception during defecation was common in asymptomatic young volunteers. The wide range of defacographic measurements warrants the necessity of other complementary studies on anorectal function to improve the diagnostic accuracy. The interpretation of defecographic measurement should therefore be made with caution and should not be used as the sole criteria for selection of treatment modality

    To examine the impact of work and volunteer hours on 4 health issues among undergraduate college students. Full-time undergraduate students (N = 70,068) enrolled at 129 institutions who participated in the Spring 2011 American College Health Association-National College Health Assessment II survey. Multiple linear regression and binary logistic regression were used to examine work and volunteer hour impact on depression, feelings of being overwhelmed, sleep, and physical activity. The impact of work and volunteer hours was inconsistent among the health outcomes. Increased work hours tended to negatively affect sleep and increase feelings of being overwhelmed. Students who volunteered were more likely to meet physical activity guidelines, and those who volunteered 1 to 9 hours per week reported less depression. College health professionals should consider integrating discussion of students' employment and volunteering and their intersection with health outcomes into clinical visits, programming, and other services.

    Volunteer satisfaction: Internal structure and relationship with permanence in organizations. The concept of satisfaction is considered theoretically relevant in practically all the studies that have investigated the factors that influence the permanence of volunteer participation in organizations. However, the practical results are not conclusive, perhaps due to the wide range of ways in which the concept is understood and measured. The object of this study is: to analyse the internal structure of satisfaction and to verify its relationship with volunteer duration in organizations. The results of the factor analysis yield a three-factor structure: Satisfaction with the management of the organization, Satisfaction with the tasks, Satisfaction of motivations. The three factors allow us to differentiate between individuals who remain in the organization for a period of 12 consecutive months, and those who leave earlier. The results of structural equation model analysis show that the relationship between satisfaction and the length of time that volunteers stay with the organization is affected by the intention to remain.

    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.

    This article examines the evolving nature of volunteering among American youth, ages 12 to 17, focusing on emergent pressures to volunteer, as required by high schools or to improve one's employment or education prospects after graduation. Using survey data (N = 736, mean age = 14.78, 75.1% white, 49.1% female), it finds these pressures are prevalent, related to a desire to volunteer, and both of these motivations are positively associated with volunteering. It further concludes that volunteering supplements, rather than replaces or subsumes both online and offline political behaviors among youth. This has important implications for how we understand the role of volunteering in the youngest American age cohorts, and practical implications for educators and civic proponents in terms of determining what actually increases volunteering activity.

    The objective of this study was to identify key experiences and common motifs of volunteer doctors who have participated in anaesthesia-related volunteer experiences abroad through the Health Volunteers Overseas (HVO) programme. An additional goal was to understand the effects of medical volunteerism in developing countries on the volunteers themselves. After a medical mission with HVO, anaesthesia volunteers submit a post-experience report. Twenty-five reports were randomly selected from the 58 available trip reports, including five from each of the five countries collaborating with HVO. Data in the reports were analysed using a modified grounded theory and constant comparative technique until thematic saturation was achieved. Three major discoveries emerged from the analysis of post-experience reports: (i) anaesthesia residents and attending physicians find their volunteer experiences in the developing world to be personally rewarding and positive; (ii) most participants feel their educational interventions have a positive impact on local students and anaesthesia providers, and (iii) global volunteerism poses challenges, primarily caused by lack of resource availability and communication issues. Our results give new insight into the experiences of and challenges faced by a cohort of HVO-sponsored anaesthesia volunteers while abroad and validates the positive effects these global health experiences have on the volunteers themselves. This group of anaesthesia volunteers was able to further their personal and professional growth, sharpen their physical diagnosis and clinical reasoning skills in resource-poor environments and, most importantly, provide education and promote an exchange of ideas and information. © 2013 John Wiley & Sons Ltd.

    To determine the spectrum of magnetic resonance (MR) imaging findings at the calcaneal attachment of the plantar fascia in asymptomatic volunteers. The study was approved by the institutional review board, and informed consent was obtained from all subjects. MR imaging was performed in 77 asymptomatic volunteers (mean age, 48.0 years; age range, 23-83 years) with use of a 1.5-T system. There were 40 women (mean age, 49.0 years; age range, 24-83 years) and 37 men (mean age, 48.0 years; age range, 23-83 years). Signal intensity characteristics and thickness of the medial, central, and lateral fascicles of the plantar fascia were assessed independently by two radiologists. The presence of soft-tissue edema, bone marrow edema, and bone spur formation at the attachment of the plantar fascia was noted. Datasets were analyzed with inferential statistic procedures. The mean thickness of the plantar fascia was 0.6 mm (medial fascicle), 4.0 mm (central fascicle), and 2.3 mm (lateral fascicle). Increased signal intensity in the plantar fascia was seen with the T1-weighted sequence in 16 of the 77 volunteers (21%), the T2-weighted sequence in six (7.8%), and the short inversion time inversion-recovery sequence in six (7.8%). Soft-tissue edema was seen deep to the plantar fascia in five of the 77 volunteers (6.5%) and superficial to the plantar fascia in 16 (21%). A calcaneal spur was detected in 15 of the 77 volunteers (19%). Calcaneal bone marrow edema was present in four volunteers (5.2%). T1-weighted signal intensity changes in the plantar fascia, soft-tissue edema superficial to the plantar fascia, and calcaneal spurs are common findings in asymptomatic volunteers and should be used with caution in the diagnosis of plantar fasciitis. Increased signal intensity within the plantar fascia with fluid-sensitive sequences is uncommon in asymptomatic volunteers.

  3. Considering the context: social factors in responses to drugs in humans.

    Drugs are typically used in social settings. Here, we consider two factors that may contribute to this observation: (i) the presence of other people may enhance the positive mood effects of a drug, and conversely, (ii) drugs may enhance the value of social stimuli. We review evidence from controlled laboratory studies with human volunteers, which investigated either of these interactions between social factors and responses to drugs. We examine the bidirectional effects of social stimuli and single doses of alcohol, stimulants, opioids, and cannabis. All four classes of drugs interact with social contexts, but the nature of these interactions varies across drugs, and depends on whether the context is positive or negative. Alcohol and stimulant drugs enhance the attractiveness of social stimuli and the desire to socialize, and social contexts, in turn, enhance these drugs' effects. In contrast, opioids and cannabis have subtler effects on social interactions and their effects are less influenced by the presence of others. Overall, there is stronger evidence that drugs enhance positive social contexts than that they dampen the negativity of unpleasant social settings. Controlled research is needed to understand the interactions between drugs of abuse and social contexts, to model and understand the determinants of drug use outside the laboratory.

    Full Text Available Context: Training programs for volunteers prior to their working in palliative care are well-established in India. However, few studies report on continuing professional development programs for this group. Aims: To conduct a preliminary assessment of educational needs of volunteers working in palliative care for developing a structured formal continuing professional development program for this group. Settings and Design: Cross-sectional observational study conducted in the Department of Palliative Medicine of a tertiary care cancer institute in India. Materials and Methods: Participant volunteers completed a questionnaire, noting previous training, years of experience, and a comprehensive list of topics for inclusion in this program, rated in order of importance according to them. Statistical Analysis Used: Descriptive statistics for overall data and Chi-square tests for categorical variables for group comparisons were applied using Statistical Package for Social Sciences version 18. Results: Fourteen out of 17 volunteers completed the questionnaire, seven having 5-10-years experience in working in palliative care. A need for continuing professional development program was felt by all participants. Communication skills, more for children and elderly specific issues were given highest priority. Spiritual-existential aspects and self-care were rated lower in importance than psychological, physical, and social aspects in palliative care. More experienced volunteers (>5 years of experience felt the need for self-care as a topic in the program than those with less (<5-years experience ( P < 0.05. Conclusions: Understanding palliative care volunteers′ educational needs is essential for developing a structured formal continuing professional development program and should include self-care as a significant component.

    Verbal and visual recognition tasks were administered to 40 patients with schizophrenia and 40 healthy comparison subjects. The verbal recognition task consisted of discriminating between 16 target words and 16 new words. The visual recognition task consisted of discriminating between 16 target pictures (8 black-and-white and 8 color) and 16 new pictures (8 black-and-white and 8 color). Visual recognition was followed by a spatial context discrimination task in which subjects were required to remember the spatial location of the target pictures at encoding. Results showed that recognition deficit in patients was similar for verbal and visual material. In both schizophrenic and healthy groups, men, but not women, obtained better recognition scores for the colored than for the black-and-white pictures. However, men and women similarly benefited from color to reduce spatial context discrimination errors. Patients showed a significant deficit in remembering the spatial location of the pictures, independently of accuracy in remembering the pictures themselves. These data suggest that patients are impaired in the amount of visual information that they can encode. With regards to the perceptual attributes of the stimuli, memory for spatial information appears to be affected, but not processing of color information.

    Full Text Available Volunteer tourists’ motivations for choosing homestay accommodation have received little attention from researchers. The objective of this research was to explore the push and pull factors that account for volunteer tourists’ choice of homestay in the Kumasi Metropolis of Ghana. Insights gained from this study will inure better understanding of volunteer tourists’ behaviour to ensure appropriate service delivery by homestay providers. With the help of the "Push and Pull" motivation model by Dann (1977, the findings indicated two main push factors: socio-cultural immersion and economic value; and pull factors: environmental sensitiveness and community service and development. The study found that the most important push and pull factors as perceived by volunteers to Ghana are socio-cultural immersion and environmental sensitiveness. The study confirms the supporting role of homestay for volunteer tourists to Ghana. In the end, the implications of this study are discussed.

    Full Text Available Purpose: To understand the meanings of volunteer work among members of a lutheran protestant church. Originality/gap/relevance/implications: This research adds to the field of knowledge of the meanings of work, especially because of the specific context studied. In addition, it extends the discussion on volunteering, by entering the management of religious institutions that are supported by the help of volunteers. Key methodological aspects: A qualitative approach to research was adopted and data were gathered in documents, interviews, and non-participant observation of the board meetings of a lutheran church synod in Southeast Brazil. The perspective used to analyze data was that the production of meanings is also a means for interpreting. Besides, using associating ideas mapping technique allowed the identification of categories based on the content and logical sequence of discourse. Summary of key results: The study found eight meanings of work: identification with the lutheran ethics; integrity and image of the institution; unit; conditions and willingness to participate; incentive from others; relation with the profession; pleasant relationship between a board of directors; and monitoring, support, and recognition. Key considerations/conclusions: The study revealed a better understanding for volunteering at a religious organization on how to think about ways to manage it. Also, it was realized that the experiences and interaction with others shape the individual and his or her relationship with the church, and that the meaning of work has a different relationship to each religion.

    METRIC is an architecture for a simple but powerful Reduced Instruction Set Computer (RISC). Its speed comes from the simultaneous processing of several instruction streams, with instructions from the various streams being dispatched into METRIC's execution pipeline as they become available for execution. The pipeline is thus kept full, with a mix of instructions for several contexts in execution at the same time. True parallel programming is supported within a single execution unit, the METRIC Context Unit. METRIC's architecture provides for expansion through the addition of multiple Context Units and of specialized Functional Units. The architecture thus spans a range of size and performance from a single-chip microcomputer up through large and powerful multiprocessors. This research concentrates on the specification of the METRIC Context Unit at the architectural level. Performance tradeoffs made during METRIC's design are discussed, and projections of METRIC's performance are made based on simulation studies.

    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.

    Full Text Available The continued participation of volunteers in clinical trials is crucial to advances in healthcare. Few data are available regarding the satisfaction and impressions of healthy volunteers after participation in phase I trials, many of which lead to unexpected adverse events. We report feedback from over 100 adult volunteers who took part in a first-in-human trial conducted in a high-income country testing an experimental Ebola vaccine causing significant reactogenicity, as well as unexpected arthritis in one fifth of participants. The anonymous, internet-based satisfaction survey was sent by email to all participants upon their completion of this one-year trial; it asked 24 questions concerning volunteers' motivations, impressions of the trial experience, and overall satisfaction. Answers were summarized using descriptive statistics. Of the 115 trial participants, 103 (90% filled out the survey. Fifty-five respondents (53% were male. Thirty-five respondents (34% were healthcare workers, many of whom would deploy to Ebola-affected countries. All respondents cited scientific advancement as their chief motivation for participation, while 100/103 (97% and 61/103 (59% reported additional "humanitarian reasons" and potential protection from Ebolavirus, respectively. Although investigators had documented adverse events in 97% of trial participants, only 74 of 103 respondents (72% recalled experiencing an adverse event. All reported an overall positive experience, and 93/103 (90% a willingness to participate in future trials. Given the high level of satisfaction, no significant associations could be detected between trial experiences and satisfaction, even among respondents reporting adverse events lasting weeks or months. Despite considerable reactogenicity and unexpected vaccine-related arthritis, all survey respondents reported overall satisfaction. While this trial's context was unique, the positive feedback is likely due at least in part to the

    Today's online banking is a convenient mode of finance management. Despite the ease of doing online banking, there are people that still sceptical in utilizing it due to perception and its security. This paper highlights the subject of online banking security in Malaysia, especially from the perspective of the end-users. The study is done by assessing human computer interaction, usability and security. An online survey utilising 137 participants was previously conducted to gain preliminary insights on security issues of online banking in Malaysia. Following from those results, 37 participants were interviewed to gauge deeper understanding about end-users perception on online banking within the context of usable security. The results suggested that most of the end-users are continuingly experiencing significant difficulties especially in relation to the technical terminologies, security features and other technical issues. Although the security features are provided to provide a shield or protection, users are still incapable to cope with the technical aspects of such implementation.

    1. Phase I clinical trials are usually carried out in healthy volunteers. In addition to economic gain, factors that may influence willingness to participate include scientific interest, curiosity and choice for risky activities. 2. We assessed the relationship between personality variables and volunteering for clinical pharmacology research. Two personality questionnaires, the Sensation Seeking Scale (SSS, form V) and the Eysenck Personality Questionnaire (EPQ), were administered to 48 male healthy university students who volunteered to participate in a phase I clinical trial and to 43 male university students who were not willing to participate in phase I clinical trials. General norm data were also used for the comparison of results. 3. When healthy volunteers were compared with unwilling subjects, significant differences were found in thrill-and-adventure seeking (7.9 vs 6.7, P = 0.0034), experience seeking (6.4 vs 5.2, P = 0.0012), disinhibition (6.2 vs 4.3, P personality profile of healthy volunteers was characterized by a higher sensation seeking trait and extraversion as compared with individuals who were not willing to participate in phase I clinical trials and general norm data.

    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.

    Recruiting volunteers who can provide computational time, programming expertise, or puzzle-solving talent has emerged as a powerful tool for biomedical research. Recent projects demonstrate the potential for such 'crowdsourcing' efforts in immunology. Tools for developing applications, new funding opportunities, and an eager public make crowdsourcing a serious option for creative solutions for computationally-challenging problems. Expanded uses of crowdsourcing in immunology will allow for more efficient large-scale data collection and analysis. It will also involve, inspire, educate, and engage the public in a variety of meaningful ways. The benefits are real - it is time to jump in! Copyright © 2015 Elsevier Ltd. All rights reserved.

    Experimental viral disease studies in volunteers have clarified many aspects of the pathogenesis of human viral disease. Recently, interest has focused on rhinovirus-associated asthma exacerbations, and new volunteer studies have suggested that airway responsiveness (AR) is enhanced during a cold. For scientific, ethical and safety reasons, it is important to use validated methods for the preparation of a virus inoculum and that the particular virological characteristics and host responses should not be altered. We have prepared a new human rhinovirus (HRV) inoculum using recent guidelines and assessed whether disease characteristics (for example, severity of colds or changes in AR) were retained. Studies were conducted in 25 clinically healthy volunteers using a validated HRV inoculum in the first 17 and a new inoculum in the subsequent eight subjects. Severity of cold symptoms, nasal wash albumin levels and airway responsiveness were measured, and the new inoculum was prepared from nasal washes obtained during the cold. The new inoculum was tested using standard virological and serological techniques, as well as a polymerase chain reaction for Mycoplasma pneumoniae. No contaminating viruses or organisms were detected and the methods suggested were workable. Good clinical colds developed in 20 of the 25 subjects and median symptom scores were similar in the validated and new inoculum groups (18 and 17.5, respectively; p=0.19). All subjects shed virus, and there were no differences noted in viral culture scores, nasal wash albumin and rates of seroconversion in the two groups. Although airway responsiveness increased in both groups (p=0.02 and p=0.05), the degree of change was similar. We have performed experimental rhinovirus infection studies and demonstrated similar clinical disease in two inoculum groups. Amplified airway responsiveness was induced; continuing studies will define the mechanisms and suggest modes of treatment.

    Perception of thermal pain (cold induced) was studied in 106 volunteers from troops and civilians deployed in J & K. Thermal stimulus devised was "holding ice". Tolerance time of holding ice was taken to be a measure of thermal sensitivity, volunteers were classified based on their native areas, addiction habits and socio-economic status, out of 106 volunteers, 81 could & 25 could not hold ice over 10 min. Sixteen out of 40 from coastline States and 9 out of 66 from non-coast line States failed to hold ice over 10 min. In "below average" "average" and "high average" socio-economic groups, three out of 27, 19 out of 73 and 03 out of 6 failed to hold ice over 10 min respectively. Fifteen out of 64 from "addiction habit group" and 10 out of 42 from "no addiction habit group" failed to hold ice over 10 min. Statistically no classification used in the study revealed significant difference in "tolerance times" of volunteers except the one based on coastline and non-coastline States.

    Samaritan listening volunteers provide emotional support to people in distress or suicidal. Samaritans' has high volunteer turnover, which may be due to burnout. This study evaluated the role of demographic and psychosocial factors in predicting Samaritans listening volunteers' burnout and health status. Samaritans' listening volunteers (n = 216) from seven branches across UK completed an online survey to assess their levels of burnout (emotional exhaustion, depersonalisation, personal accomplishment), subjective health status, coping, empathy and social support. Overall, listeners showed low levels of burnout and good health. Regression analysis revealed that higher emotional exhaustion was predicted by younger age and avoidant coping style; higher depersonalisation was predicted by lower empathy fantasy and higher avoidant coping style; lower personal accomplishment scores were predicted by higher empathy personal distress and worse health status was predicted by more hours per week spent on listening duties, lower social support and higher avoidant coping style. Overall, different factors influenced different facets of burnout. However, higher use of avoidant coping style consistently predicted higher burnout and worse health status, suggesting avoidant coping is an important target for intervention.
