The Give and Take of Volunteering: Motives,Benefits, and Personal Connections among Irish Volunteers
Pádraig MacNeela 《Voluntas: International Journal of Voluntary and Nonprofit Organizations》2008,19(2):125-139
Volunteers are integral to the delivery of health and social services in many countries. Volunteer motivation is the key phenomenon around which research into the psychology of volunteering behaviour has been based in the recent past. This study comprised interviews with 26 volunteers working with eight health and social care organizations in Ireland. The study aimed to describe and interpret reasons for initial and continued volunteering involvement. Four key themes were proposed on the basis of a thematic analysis: volunteer motives; personal connections to organizations and causes; benefits; and challenges arising from volunteering. These themes are analysed in light of social psychological theory to better understand why people volunteer and maintain their involvement in the face of competing demands. The findings suggest that benefits and challenges merit a higher profile in research into the volunteer process, and that bonds of perceived obligation motivate many volunteers to begin and continue their involvement in health and social care. 相似文献

Price deflators for semiconductors fell rapidly over the 1990s, pulled down by steep declines in the deflator for the microprocessor (MPU) segment that accelerated around 1995. A decomposition of a price index for Intel's MPUs suggests that virtually all of the declines in the price index—and the acceleration—can be attributed to quality increases associated with product innovation, rather than declines in the cost per chip. The sizable decline in Intel's margins from 1993–99 only accounted for about 6 percentage points of the average 24% decline per quarter in the price index and cannot explain the acceleration.

The conditional specification technique introduced by Arnold et al. (Conditional specification of statistical models. Springer
series in statistics. Springer, New York, 1999) was used in Sarabia et al. (Astin Bull 34(1):85–98, 2004) to obtain bonus-malus
premiums. The Poisson distribution for which the parameter is a function of the classical structure parameter was used and
a new class of prior distributions appeared in a natural way. This model contains, as a particular case, the classical compound
Poisson model. In the present paper, the Bayesian robustness of this new model is examined and found to be much more robust
than in the classical model in Gómez et al. (Insur Math Econ 31:105–113, 2002). For the present study, the moment conditions
on the prior distribution are required. Examples, with real data, are given to illustrate our ideas under the net and exponential
premium principles. 相似文献

This paper describes the emergence of anti-war initiatives in the former Yugoslavia against the background of the official nationalism of Communist elites and their post-1990 successors. The author argues that anti-war activism in the disintegrating state was a mobilization of the most articulate segment of a widespread, all-Yugoslav, urban, cosmopolitan and genuinely non-ethnonationalistic cultural identity. One of the reasons behind its easy suppression by the official rhetoric of ethnic homogeneity is its purely cultural stance and lack of experience in alternative forms of political organization. Dominant approaches to ethno-nationalism in former Yugoslavia are criticised for essentializing ethnic identities, and contrasted with some interpretive approaches that analyze the structural preconditions of ethno-nationalism as top-to-bottom projects of the ex-Communist middle-to-high ranking functionaries in search of legitimacy and forced to create a 'democratic electorate.' 相似文献

Consider a random sample X1, X2,…, Xn, from a normal population with unknown mean and standard deviation. Only the sample size, mean and range are recorded and it is necessary to estimate the unknown population mean and standard deviation. In this paper the estimation of the mean and standard deviation is made from a Bayesian perspective by using a Markov Chain Monte Carlo (MCMC) algorithm to simulate samples from the intractable joint posterior distribution of the mean and standard deviation. The proposed methodology is applied to simulated and real data. The real data refers to the sugar content (oBRIX level) of orange juice produced in different countries. 相似文献

We asked daytime university and college students to complete the survey, which aimed at examining the authoritarian attitude of those questioned, and the factors in connection to it. The questionnaire was made up of 23 statements, and those questioned had to express how far they agree on a five grade scale (N = 349). On the basis of the answers it could be stated that the different groups of those planning to work in different fields differ from each other also from the point of view of accepting authority: from those groups which were examined in greater numbers the physical education teachers and the theologians were the most authoritarian, while the social workers and students of human studies were the least. Those answering differed also in terms of religiousness: those considering themselves religious and close to the church seemed to be the most authoritarian and those who are not religious the least. The results were interestingly coloured by the fact that in assessing specific social situations the social workers and the convinced non-religious ones showed signs of more authoritarian attitude. Results also proved that the own opinion about authoritarianism is related to the opinion of the parents. Beside many other questions we also examined whether authoritarianism is related to the situation when someone is stricter to him/herself and to those emotionally closer than to others. 相似文献

Integrated schooling is known to induce interethnic friendship relations; however, it also creates the opportunity of interethnic dating. Interethnic personal relationships or long-term exposure decreases ethnic prejudice, thus it is proposed that willingness to date between ethnic groups may also increase. The question arises, whether in the school context exposure is enough for this mechanism to emerge, or personal contact is necessary. It must also be taken into account that romantic relationships are embedded in status relations within schools. Based on a ‘social exchange’ mechanism, it is assumed that the less popular members of the majority groups are those who are more willing to form interethnic dating relations. To address the above questions empirically, the data of 1213 Hungarian 9th grade students in 43 classes were analysed. Preferences of Roma and non-Roma students were measured by dyadic attribution of physical attractiveness and nominations of willingness to date. Results of multilevel p2 models suggest that mixed groups are not sufficient, but personal contacts are necessary to decrease same-ethnicity preferences in dating. An additional tendency is salient: among majority students, those who are isolated from the friendship networks are the ones who are more willing to date members of the minority group. 相似文献

The purpose of this research is to analyze the different factors that determine the level of time devoted to volunteer activity involving employed people. To this end, we applied a logistic regression model to a sample of 5,067 employees, considering four categories of factors: family and personal, on the one hand, and contextual factors, on the other. This second group involves three factor categories: occupational, organizational, and community involvement factors. The findings of this work are especially relevant to two areas: first, to design a policy of corporate social responsibility that effectively integrates the figure of corporate volunteering, considering its pertinent factors; and second, to broaden the perspective of the third‐sector organizations beyond the traditional profile with which volunteers are commonly associated. 相似文献
