We assessed beliefs about adult children’s responsibilities to financially assist parents and stepparents following later-life divorce and remarriage using a multiple-segment factorial vignette with a national sample (N = 1,121). Ordered logistic regression analyses indicated that beliefs about financial responsibilities to older adults declined after marital transitions, and responsibilities to assist stepparents were more tenuous than to parents. Beliefs about intergenerational responsibilities were affected by adult children’s financial resources and by changes in older adults’ marital statuses. Kinship obligation norms, the adult children’s financial resources, and reciprocity norms were the most common reasons used to explain beliefs about responsibilities to financially assist older parents and stepparents, but these reasons became less salient following divorce and remarriage of the older adult. After marital transitions, beliefs about intergenerational financial responsibilities were more often based on the older adult’s culpability for being in a position of need, relationship quality, and diminished kinship obligations.  相似文献

Vocal plasticity may allow birds to reduce masking effects of noise pollution arising from urbanization. Mountain chickadees (Poecile gambeli) use both songs and calls during the dawn chorus, which vary in masking susceptibility. Thus, increasing song or call frequency, or switching between vocalization types are all potential mechanisms to reduce masking during fluctuating noise conditions. Further, prior experience with noise pollution may be a necessary precursor to allow birds to alter signals in response to sudden noisy conditions. To determine how mountain chickadee songs, calls, and chorus composition are affected by noise, we recorded 55 males across gradients of local ambient noise and habitat urbanization in three cities in British Columbia, Canada. Of these individuals, 31 were also exposed to 5-min experimental noise treatments. Habitat urbanization was quantified through a continuous index reflecting properties of urbanized areas. Only song frequency increased with local ambient noise, and this effect varied regionally. In response to experimental noise exposure, males increased the frequency of their calls (but not of their songs), and varied their use of songs vs. calls. Interestingly, this response was dependent on local ambient noise levels: males in noisy areas shifted to using relatively more songs, whereas males in quiet areas shifted to using relatively more calls. These findings may suggest that although mountain chickadees are capable of adjusting their vocalizations, choosing a response which can lead to masking release may require prior exposure to high levels of ambient noise.  相似文献

Grounded in affection exchange theory (AET; Floyd, 2006), this study examined the extent to which affection received from grandparents is associated with grandchildren’s perceptions of their grandparents and their grandparent-grandchild relationship (in the form of emotional closeness, shared family identity, and perceived availability of social support). Young adult grandchildren (= 171) completed several instruments in reference to their relationship with a specific grandparent. The results of multiple regression analyses generally supported the hypotheses that received affection is associated positively with grandchildren’s perceptions of their grandparents and their grandparent-grandchild relationship. These findings support AET’s utility in the grandparent-grandchild relationship and the notion that grandparents often influence their grandchildren’s perceptions of their family.  相似文献

In our prior article in this issue, we establish that although they are related, organizational and group dynamics are in fact very different. In this second article, we go on to discuss some of the challenges that this poses for consultants. We describe the interplay of factors affecting the development of the dynamics within an organization and explore approaches to acquiring practical knowledge about an organization’s dynamics. Finally, we ask how useful group dynamics skills are for providing consultancy services within and to organizations and consider where and how specific organizational dynamics skills can be acquired.  相似文献

ABSTRACT

This special section builds upon Deirdre Boden’s work on the constitutive nature of talk for organizations and the Culture & Organization 2004 special issue that developed her concern. Specifically, we aim to further engage with how business is managed, formed and locally accomplished by means of the organizational surroundings that the participants make themselves part of and the multimodal resources that they have at their disposal, in other words: how people live the organizational surroundings. Our hope is to shed light on future directions in the multimodal analysis of workplace interaction and studies of organization in general, and encourage a further interconnection among scholars from various disciplines.  相似文献

This study considers the coverage of women’s sports and the involvement of women in newspaper sports journalism in the United States, the United Kingdom, and Australia. Results of a content analysis (N = 3,382) show that the coverage of, and professional opportunities for, women and men are far from equal in sports media. Further, results of a survey of professional journalists (N = 298) show that despite a widespread acknowledgment of the inequities that exist, male journalists remain significantly less likely than female journalists to report supporting an increased role for women within  相似文献

In this article, we present the results of three question design experiments on inter-item correlations, which tested a grid design against a single-item design. The first and second experiments examined the inter-item correlations of a set with five and seven items, respectively, and the third experiment examined the impact of the question design on inter-item correlations of follow-up questions. We found that the inter-item correlations in grid designs were higher for both the set of five and seven items than for questions in a single-item design. Additionally, the inter-item correlations of the set of follow-up questions were higher if the preceding set of questions was presented in a grid. According to the findings of the present research, respondents seem to apply the interpretative near means related heuristic when answering grid questions, and also when answering follow-up questions preceeded by grid questions.  相似文献

Scheduling–Location (ScheLoc) problems integrate the separate fields of scheduling and location problems. In ScheLoc problems the objective is to find locations for the machines and a schedule for each machine subject to some production and location constraints such that some scheduling objective is minimized. In this paper we consider the discrete parallel machine makespan ScheLoc problem where the set of possible machine locations is discrete and a set of n jobs has to be taken to the machines and processed such that the makespan is minimized. Since the separate location and scheduling problem are both \(\mathcal {NP}\)-hard, so is the corresponding ScheLoc problem. Therefore, we propose an integer programming formulation and different versions of clustering heuristics, where jobs are split into clusters and each cluster is assigned to one of the possible machine locations. Since the IP formulation can only be solved for small scale instances we propose several lower bounds to measure the quality of the clustering heuristics. Extensive computational tests show the efficiency of the heuristics.  相似文献

Should the individual voting records of central bankers be published?   总被引:1,自引:0,他引:1  
We examine whether the publication of the individual voting records of central-bank council members is socially beneficial when the public is unsure about the efficiency of central bankers and central bankers are angling for re-appointment. We show that publication is initially harmful since it creates a conflict between socially desirable and individually optimal behavior for somewhat less efficient central bankers. However, after re-appointment, losses will be lower when voting records are published since the government can distinguish highly efficient from less efficient central bankers more easily and can make central bankers individually accountable. In our model, the negative effects of voting transparency dominate, and expected overall losses are always larger when voting records are published.  相似文献

By presenting some results of an extensive reconstruction of George Herbert Mead's work published as yet only in German it is argued that Mead's work as a whole and particularly his social psychology contain an implicit conception of social order. This can be characterized as the idea that it is not normative integration as such, but communicative coordination that makes possible human society and social order. This is shown by findings on the early development of Mead's ideas (Hegelianism, Definition of the Psychical), on German influences in Mead, and on the meaning of democracy as self-government in Mead's political biography. Some hints to a comparison of Mead with other concepts of social order (Durkheim; negotiated order approach) are given.  相似文献
