Stepfamily education programs are becoming increasingly common. While research on these programs is also increasing, the extant literature tends to be quantitative and cross-sectional. To more fully understand the stepfamily education experience, this case study focuses on the perceptions, feelings, and reports of one participating couple in the Smart Steps program. The nuances and complexities of this single case highlight the sequentiality and reasons for seeking out and participating in stepfamily education. A holistic portrayal of the perceived benefits of attending is also provided, including improvements with spouse, ex-spouse, and children.  相似文献

This study examines the locations of Protestant churches in the Chicago region between 1925 and 1990 based on data from the Church Federation of Greater Chicago. The analysis adds two insights to existing explanations of white flight and the corresponding suburbanization of churches: suburbanization patterns were not the same across Protestant groups and churches moving to the suburbs were adding to churches already present in those communities. As the percentage of suburban Protestant churches in the Chicago region started increasing after 1925, the new suburban locations were influenced by settlement patterns in the Chicago region—first along railroad lines and then in between with new sites easier to access by automobile—in addition to racial changes in Chicago neighborhoods and the ethnic composition of denominations. Suggestions for further research include examining the suburbanization of religious groups in more metropolitan regions (particularly beyond the North), comparing the discussions about moving to the suburbs across denominations and congregations, and considering how religious congregations have helped shape suburban communities.  相似文献

Similarity and familiarity with partner’s attitudes are linked to positive relationship outcomes, while interpersonal variables have been linked to mental health. Using multilevel models (MLMs), we modeled the associations between these attitudinal variables and mental health outcomes in 74 married couples. We found that higher levels of attitude similarity in couples were linked to lower depression, while higher levels of attitude familiarity in couples were associated with greater satisfaction with life. Mediational analyses indicated marital satisfaction and interpersonal stress mediated the link between attitude similarity and depression. Marital satisfaction also mediated the link between familiarity and satisfaction with life. This study is the first linking attitude familiarity to mental health and provides evidence that familiarity and similarity have mental health effects partly due to their interpersonal consequences.  相似文献

In this paper I attempt to unpack the current public debate on racial transformation in South African sport, particularly with regard to the demographic make-up of its national cricket and rugby sides. I ask whether the alleged moral imperative to undertake such transformation is, in fact, a moral imperative at all. I discuss five possible such imperatives: (1) the need to compensate non-white South Africans for the injustices in sport's racist history, (2) the imperative to return the make-up of our national sides to what they would have been in the absence of that history, (3) the requirement that national sides be representative of the country, (4) the need to eliminate ongoing racial bias in selection, and (5) the obligation to provide all South Africans, regardless of their race, the opportunity to compete as equals for places in the national side. I argue that the first three, drawn from talk of “rectifying the injustices of the past”, “achieving demographic proportionality between the sides and the country”, “representivity”, and “transformation” itself, are not compelling. The remaining two are of great moral import, but, I argue, they have little to do with the sorts of phrases just mentioned, and which are frequently used in the debate.  相似文献

The prevalence of reading difficulties (RD) reflects controversial data ranging from 3.1–3.2% to 17.5%. Possible explanations are partly based on the incidence of orthography-specific factors influencing the reading process, but also on methodological differences that hinder comparison of the reported results. For this reason, the present study aims to analyse the prevalence of RD in a sample of 1,408 Spanish-speaking school children by comparing different ways of calculating the prevalence rate. The results reflect a prevalence of 2.2?5.3%, consistent with data reported for predominantly transparent orthographies. Some of the procedures used to identify RD are more accurate in early school years than at more advanced moments of schooling. Furthermore, the consideration of students’ sex when calculating the prevalence of RD seems to represent a more sensitive way of identifying students with RD.  相似文献
