This paper takes an initial step toward a better understanding of the complex set of pressing problems that need to be addressed by the Eastern European nonprofit sectors and their supporters in the near future. It gives an overview of the main challenges and claims that different nonprofit sectors of the region are at different crossroads. It identifies a general policy crisis that is fueled by the lack of a comprehensive knowledge of the sector and clear political intentions of cooperating with it. In addition, the dependence on foreign funding may result in a sustainability crisis in several Eastern European countries. In the most developed part of the region, the main elements of the present crisis are the fiscal, economic, effectiveness, identity, and legitimacy problems, which have something in common with the challenges facing the much more mature nonprofit sectors of the developed world. 相似文献

In this article, we investigate cosmopolitan attitudes among the people often considered the most cosmopolitan – the elite. Studying the typical class of frequent travellers provides a particularly good opportunity to study the relationship between transnational activities and cosmopolitanism. We also comprehensively investigate the link between postmaterialist values and cosmopolitan attitudes. We test our arguments using an original dataset that includes a relatively large sample of the German positional top elite in the years 2011 and 2012. A comparison between these data and data from a general population survey shows that while transnational activities affect the attitudes of ordinary citizens, increased travelling does not make elites more cosmopolitan. We discuss several reasons why this might be the case. We also observe that postmaterialist values and the ideological environment of the elite play a key role. Finally, we tentatively suggest that cosmopolitan elites do not endanger national social cohesion, as some fear they might. We show that cosmopolitanism and localism are not mutually exclusive and that members of the German elite feel even more attached to their nation than ordinary Germans. 相似文献

Objectives. The article examines the factors that influence the frequency whereby scholarly articles published by Canadian political scientists are cited. Method. We collected data on 1,860 journal articles published between 1985 and 2005 by 758 Canadian political scientists and listed in the Social Science Citation Index. Using these data, we performed OLS and tobit estimations to identify factors influencing citation frequency. Results. The regressions show that the reputation of the journal in which the article is published, though important, does not explain everything. The gender of the author(s), the number of authors, the geographical focus of the article, the field, and the methodology also matter. Conclusion. An article is more likely to be widely cited if it is published in a prestigious journal, if it is written by several authors, if it applies quantitative methods, if it compares countries, and if it deals with administration and public policy or elections and political parties. Faculty members who belong to larger departments and those who are women are more cited. 相似文献

Many assays have been carried out in Capsicum spp. in order to evaluate its resistance to Phytophthora capsici , which causes blight and considerable yield loss. An assay aiming at the selection of resistant pepper and bell pepper genotypes to P. capsici was jointly performed in the laboratory of the Phytopathological Clinic of Entomology, Phytopathology and Agricultural Zoology and in the experimental area of the Plant Production Department, both located at ESALQ, University of São Paulo, Brazil. The data set for this assay comes from ordinal categorized random variables, whose analysis does not generally take into account the ordinal nature of the responses, but instead, builds indexes, among other measures, in order to evaluate the resistance of the studied genotypes. This work presents ordinal generalized linear fits in order to evaluate blight severity as well as to identify and select new resources to the pathogen. It also analyses the estimating equations proposed by Liang & Zeger (1986a, b) in order to obtain an infection pattern for the disease. From the fit of the cumulative logit models, valuable genotypes are identified for genetic breeding programs. 相似文献

We study a problem of model selection for data produced by two different context tree sources. Motivated by linguistic questions, we consider the case where the probabilistic context trees corresponding to the two sources are finite and share many of their contexts. In order to understand the differences between the two sources, it is important to identify which contexts and which transition probabilities are specific to each source. We consider a class of probabilistic context tree models with three types of contexts: those which appear in one, the other, or both sources. We use a BIC penalized maximum likelihood procedure that jointly estimates the two sources. We propose a new algorithm which efficiently computes the estimated context trees. We prove that the procedure is strongly consistent. We also present a simulation study showing the practical advantage of our procedure over a procedure that works separately on each data set. 相似文献

Which of the three dimensions of Allardt’s model, “having, loving, and being”, best predicts the incidence of subjective feeling of well-being among the Canadian Arctic Inuit adults? To answer this question, two logistic regression equations have been constructed, one based on a negative assessment of well-being (feeling of despair), and the other on a positive assessment (satisfaction with life in the community). Each of them took first the form of a global model, and then of three scale models, one for each dimension of the Allardt’s model. The equations are likely to be more effective for predicting the incidence of Inuit’s feeling of satisfaction than for anticipating their feeling of despair. Furthermore, the “being” scale model is the one that will have contributed most to the predictive performance of the global model. In other words, what the Inuit “ARE” contributes more to the incidence of their satisfaction with life than what they “HAVE” or what they “LOVE”. 相似文献

The frequency of union dissolutions increased sharply over the past 40 years in Western Europe and North America, resulting in a rapid growth in the number of persons living with a second partner. In studies of the 1980s, primarily conducted within the context of marriage, second partnerships were generally found to be less stable than first unions, but more recent studies provide more conflicting evidence. Taking the example of France, we study whether the relationship between first and second union stability indeed reversed between the 1970s and the 2000s, and how union and individual characteristics contributed to changes over time. The analysis presented here is based on the French Generations and Gender Survey (2005). The article first provides an overview of the differences in marriage, childbearing and breakup behaviours in first and second unions. Second, a piecewise linear model for repeated events is used to compare women’s dissolution risks in first and second unions. The results show that over time, the higher instability of second compared to first unions disappeared. Further, women in second unions adopted unmarried cohabitation as a living arrangement more often across the whole period and were more likely to have stepchildren, which was associated with less stable unions. Taking into account this diversity of family situations, i.e. controlling for family form and children, second unions were more stable than first unions, even during the past. At both union orders, marriage breakup risks tended to stabilise despite a continuing increase in the prevalence of separation, which suggests that cohabitation increasingly acts as a filter for marriage. 相似文献

Shiftwork-induced sleep deprivation and circadian disruption probably leads to an increase in the production of cytokines and dysregulation of innate immune system, respectively. This project aims evaluating changes in salivary IL-1 beta, cortisol, and melatonin in night workers. Method. Two day and three night healthy workers participated in this study. Sleep was evaluated by actimetry and activity protocols. Saliva was collected at waking and bedtime the last workday and the following two days-off and was analyzed by ELISA. Results. Neither sleep duration nor efficiency showed any association with salivary IL-1beta. IL-1beta levels were higher at waking than at bedtime during working days for all workers, but only one day and one night-worker maintained this pattern and hormone rhythms during days off. For this night worker, melatonin levels were shifted to daytime. A second one presented clear alterations in IL-1beta and hormone rhythms on days-off. Conclusions. Our preliminary results suggest that night work can disturb the variation pattern of salivary IL-1beta. No association of this variation with sleep was observed. It seems that disruption in hormone rhythms interfere with salivary IL-1beta production. IL- 1beta production pattern seems to be maintained when rhythms are present, in spite of a shift in melatonin secretion. 相似文献

Humor and Identity on Twitter: #muslimcandyheartrejects as a Digital Space for Identity Construction
Through examining the hashtag #muslimcandyheartrejects, a one-time, short-term, joke hashtag used on Twitter among a group of Muslim tweeters in 2012, we argue that members of Muslim digital diaspora communities use social media to construct and reinforce a Muslim diaspora identity. The architecture of Twitter provides the structure for these engagements, while humor serves meaning-making, cohesion building, and tension-relief functions within the conversation. The conversation itself combines a variety of topics to both describe Muslim identity in diaspora and to critique both Muslim community practices and conditions for Muslims in non-Muslim countries. 相似文献
