ABSTRACT

This qualitative study explored how 36 initially female-partnered mothers defined their own, and their children's, relationships with families who share their unknown sperm donor (i.e., “linked” families). Shared genetics among children were sometimes sufficient to describe relationships among linked families as familial, especially from the children's perspectives. Most women described their own relationships with linked families as significant but not necessarily in traditional family terms. Family terms were sometimes seen as undermining ties to siblings and genetically unrelated mothers. As shared experiences have come to define “chosen family,” definitions of significant relationships must expand to include those defined by shared genetics alone.  相似文献

We examined the association of joint trajectories of ethnic identity and criminal offending to psychosocial maturity, gang membership, and Mexican American affiliation among 300 Mexican American male juvenile offenders from ages 14 to 22. There were two low‐offending groups: one was the highest in ethnic identity and changing slightly with age and the other was the lowest in ethnic identity and stable with age. A third group displayed moderately declining offending and moderately stable ethnic identity. A fourth group displayed high‐offending individuals with moderate, but increasing, levels of ethnic identity, who were initially lower in psychosocial maturity and more likely to be gang members. The findings highlight the need to contextualize theories of ethnic identity development.  相似文献

Nowadays, reverse logistics is gaining importance for many companies in different industries. This importance is rooted in the fact that it generates profit and decreases the environmental impacts of products. Even though the decrease of environmental impacts is an indispensable requisite, reverse logistics design is only driven by cost indicators. The main reason behind this high cost is access to environmental information is difficult and is directly linked to data all along the lifecycle of the product. This paper presents a method by which reverse logistics design integrates environmental impacts based on the management of closed-loop product lifecycle. This method is divided into two processes: from beginning of life to end of life and from end of life to beginning of life. The first process integrates product data in order to calculate environmental impacts of the potential reverse logistics networks, whereas the second process selects the most appropriate reverse logistics network before optimising the product based on this particular network. The proposition is illustrated by a case study on a recycled aluminium automotive part.  相似文献

In this article we showed how the notion of heteronormative citizenship embedded in the Polish Constitution was (re)produced in the public sphere, and how heteronormativity as an ideal was slowly undermined by the emergence of new narratives on LGBT families. We did so by first conducting a critical reading of the Polish Constitution, public opinion polls, national censuses, and so forth. Then we presented the results of a discourse analysis on families of choice in Poland from crucial public debates of the last decade. Through this we identified the main public strategies of silencing and excluding, its dynamics, main actors, possible changes, and shifts over time. The results of the research showed the change that occurred in the public discourse on LGBT families in the last decades in Poland moving from defining family in very conservative and traditional terms at the beginning of the 2000s to a more open definition of family in 2010–2011. However, they also demonstrate some undesired alliances among supporters and opponents of same-sex partnership and possible dangers of some strategies used by LGBT activists.  相似文献

This paper focuses on the development of nongovernmental organizations (NGOs) in Poland, as a case study of the sector's development in the Central and Eastern European countries of transition. It is argued that, in this situation, the development and growth of the NGO sector though shaped, as in the West, by a set of legislative, political, economic, cultural, and historical forces, nevertheless is circumscribed by the specific conditions of political transformation. The nature of and the power with which legislative, fiscal, or organizational forces condition the development of the sector varies according to the scale at which they operate (local, national, or international). Moreover, it is argued that the position of NGOs is significantly regulated by the state's political ideology, and the formative and evolving character of the latter translates into instability in states' actions vis-à-vis the nonprofit sector.  相似文献
