Drawing upon insights from family research, this article argues that in modern Western societies the reflection of individual notions of family as well as the development of concepts of a fulfilling everyday family life has turned into a recurrent challenge throughout the life course, a challenge particularly relevant during family transitions. Professionals in the field of social work with families are increasingly faced with the task of supporting such processes of reflection and development. At the same time, there is little knowledge about how these processes look like. Building upon results of a pilot study and merging recent theoretical developments in family research with the (German) tradition of social pedagogy, a conceptual framework to study family concepts theoretically and empirically is developed. The potential as well as the limitations of this research approach are discussed drawing upon a case example taken from an ongoing longitudinal study. This study aims at revealing family concept-related processes of informal learning and thus provides an understanding of family development from a social pedagogic point of view. Finally, an outline will be given of how this research could contribute to develop an intervention method standing in the tradition of social pedagogy. 相似文献

Vine copulas are a flexible class of dependence models consisting of bivariate building blocks and have proven to be particularly useful in high dimensions. Classical model distance measures require multivariate integration and thus suffer from the curse of dimensionality. In this paper, we provide numerically tractable methods to measure the distance between two vine copulas even in high dimensions. For this purpose, we consecutively develop three new distance measures based on the Kullback–Leibler distance, using the result that it can be expressed as the sum over expectations of KL distances between univariate conditional densities, which can be easily obtained for vine copulas. To reduce numerical calculations, we approximate these expectations on adequately designed grids, outperforming Monte Carlo integration with respect to computational time. For the sake of interpretability, we provide a baseline calibration for the proposed distance measures. We further develop similar substitutes for the Jeffreys distance, a symmetrized version of the Kullback–Leibler distance. In numerous examples and applications, we illustrate the strengths and weaknesses of the developed distance measures. 相似文献

The degree of social reproduction varies considerably between industrialized countries, raising the question of which institutional regulations promote or restrict this process. Education is considered the main mediator of social reproduction. Because school tracking – the sorting of children according to ability and interest at different ages – is known to affect educational attainment and the degree of tracking varies strongly across countries, it may thus account for differences in social reproduction. However, empirical studies are scarce, and the total impact of tracking on social reproduction remains ambiguous. Using the European Social Survey (ESS) 2012 and 2014 from 24 countries, we demonstrate that school tracking is strongly associated with higher degrees of social reproduction. Decomposing the process of social reproduction into educational inheritance, educational returns and direct effects of social origin, we find that although all channels contribute to social reproduction, the impact of tracking seems to be exerted through educational inheritance and to a similar degree through direct effects of social origin, whereas educational returns do not seem to be affected. Even net of educational attainment, social origin thus has a stronger effect on social status in tracked systems. We ascribe this effect to differences in qualitative choices within educational tracks, such as fields of study. 相似文献

Using different case studies the author concentrates on the analysis of international assignments with regard to executive and couple coaching. It becomes clear that the success of assignments abroad largely depends on the modalities (with vs. without family) and duration of the stay, the expatriates´ cross-cultural competence and the cultural dimensions of the host country. Coaching helps to improve the work-life-balance against the background of an imminent culture shock. 相似文献

We use a recently proposed fluctuation-type procedure for detecting breaks in spatial regions to distinguish between hard and soft areas of inhomogeneous mineral subsoil like additives, air pockets, and adhesion. For a proper application, some refinements of the procedure are necessary. Both simulation evidence of the refinement and the application on the subsoil yield favorable results. 相似文献

Non-governmental organizations (NGOs) are a major institutional force in promoting sustainable development, especially in institutional environments where governments have often not been able to assume the role of development agent. Despite this importance, the approach of Latin American NGOs to sustainability has received only little attention so far and respective research is scarce. To address this research gap, we conducted an online survey of 306 Latin American NGOs, investigating their understanding of sustainability and how they seek to transmit it. Due to the lack of previous empirical studies, our study is exploratory in nature and examines eight research categories: (1) NGOs definition of sustainability; (2) the role they see for themselves in its promotion, (3) dimensions of sustainability judged as important, (4) stakeholders and (5) partners considered, (6) motives for pursuing sustainability, (7) forms of implementation, and (8) measures regarded as necessary for spreading it further. Our findings are discussed against the institutional environment of Latin America, as we assume that the understanding and transmission of sustainability is contextual in nature. Our study shows that the sustainability concept of the sample NGOs is broad and that they take a wide variety of efforts for implementing it. Exploratory and confirmatory factor analyses confirmed the reliability and validity of the eight-component-model we applied for our study. Thus, it serves as a valuable starting point for future research into the “terra incognita” of Latin American NGOs’ approach to sustainability. 相似文献

Within academic research, more and more scholars reveal the ambivalence of NGOs—the sometimes constructive, sometimes destructive role they play in solving societal problems. In this paper, we present a discourse analysis that illustrates how NGOs’ campaigning may undermine their reputation and advocacy function. We conclude that such discourse failures are frequently not merely an accidental by-product, but rather a not-intended consequence of deliberate NGOs’ campaigns. By applying ideas from political economy, we make particular note of probable discourse failures when campaigns attempt to deal with complex issues in an environment rife with wide-spread prejudices and where the NGO’s work is transparent. We present collectively institutionalized commitments for NGOs and commitment services enforced by political organizations as instruments that are suitable for increasing public accountability of the NGO sector. In conclusion, we argue that further research can benefit from systematically analyzing the interdependencies between discourses and institutions. 相似文献

When multi-plant firms face a declining demand, they typically have to close one or more locations. In that case, the firm can organize a shutdown contest among the plants to generate extra incentives. Within a two-plant model, I discuss the impact of plant size, workers’ outside options and bargaining power on the profitability of such contest. Whereas the influence of plant size is ambiguous, the firm prefers a shutdown contest to an immediate closure of the less productive location if the more productive plant’s bargaining power is large relative to that of the less productive one. In that case, the more productive workforce spends much effort and has a high probability to survive. If the multi-plant firm is an international corporation, auctioning off the decision right which plant to close can be profitable for the firm, since each country is interested in protecting its domestic plant. From the firm’s perspective, such bidding dominates a shutdown contest if national costs from plant closure are sufficiently large relative to extra profits generated by the contest. 相似文献
