Discordant couples are unique because partners do not share the same serostatus. Yet research overlooks how they became discordant, mistakenly assuming that they have always been that way and, by extension, that being discordant impacts the relationship in a similar manner. This study examines HIV infection history and its impact on relationship dynamics using qualitative data from 35 discordant gay male couples. Most couples were discordant when they met (69%); however, many were not (31%). Those couples that met discordant felt being discordant had a lesser impact on their sexual and relational satisfaction, while those that did not meet discordant felt it had a greater impact, reporting sexual frustration and anxiety over seroconverting. This suggests that relationship dynamics may differ for discordant couples depending on HIV infection history. HIV prevention and counseling services for discordant couples can be better tailored and more effective when differences in HIV infection history are recognized.  相似文献

This mixed methods study identified six elementary teachers, who, despite the widespread marginalization of elementary social studies, spent considerable time on the subject. These six outliers from a sample of forty-six Michigan elementary teachers were interviewed, and their teaching was observed to better understand how and why they deviate from the norm. An autonomy-versus-control continuum is used to frame how teachers decide what, when, and how to teach. Challenging existing literature that suggests that additional attention to elementary social studies comes from testing pressure or by providing teachers with autonomy, findings of this study reveal that five of the six teachers taught social studies frequently and extensively because their schedules were externally controlled to designate specific time for social studies instruction.  相似文献

In the general framework of quantitative methods for natural‐technological (NaTech) risk analysis, a specific methodology was developed for assessing risks caused by hazardous substances released due to earthquakes. The contribution of accidental scenarios initiated by seismic events to the overall industrial risk was assessed in three case studies derived from the actual plant layout of existing oil refineries. Several specific vulnerability models for different equipment classes were compared and assessed. The effect of differing structural resistances for process equipment on the final risk results was also investigated. The main factors influencing the final risk values resulted from the models for equipment vulnerability and the assumptions for the reference damage states of the process equipment. The analysis of case studies showed that in seismic zones the additional risk deriving from damage caused by earthquakes may be up to more than one order of magnitude higher than that associated to internal failure causes. Critical equipment was determined to be mainly pressurized tanks, even though atmospheric tanks were more vulnerable to containment loss. Failure of minor process equipment having a limited hold‐up of hazardous substances (such as pumps) was shown to have limited influence on the final values of the risk increase caused by earthquakes.  相似文献

This study examined the planning that occurred when children participated in classroom playcrafting with either adult or child leadership. In a first‐/second‐grade classroom in an innovative public school, we videotaped 11 sessions in which children volunteered to develop a play with small groups of classmates and seven sessions in which adult volunteers (parents and a grandparent) developed plays with small groups of children. The plays were crafted in one session of about an hour, and then usually performed for the class. More planning took place during child‐ than adult‐directed sessions (averaging 92 vs. 35 percent of the session's duration). The groups led by children were more frequently involved in planning of themes, planning of details of the themes, and especially in improvisationally mindstorming ideas than were the groups led by adults. In adult‐directed sessions, the adults often planned the play before the children joined the activity, and the children spent most of the session in non‐playplanning activities such as gluing and coloring puppets or rehearsal of lines designed by the adult in advance. We argue that opportunities to observe and participate in planning—which occurred more frequently in child‐directed than adult‐directed sessions—are important to the development of planning skills and of co‐ordination of plans with others.  相似文献

We focus on the scarcely researched concept of internalized racism (INR), conceptualized as the internalization by blacks of white stereotypes about blacks, to investigate the extent to which it is impacted by education. Samples were drawn from two countries in Southern Africa, Swaziland (N = 308) and Zimbabwe (N = 319). We examined the contrasting socio-political contexts of a history of apartheid in Zimbabwe, and the absence of de jure segregation in Swaziland, the levels of INR, and the relationship of education to INR in both societies. Analysis showed that there was no difference in the levels of INR. Education, our variable of main interest, was negatively related to INR in both societies, and age, and a “sense of helplessness” were positively related to INR also in both societies, although the latter was marginally significant in Swaziland. We discussed the unexpected similarity of INR levels in these societies, and the potential of education to mediate negative psychological effects in both socio-political contexts.  相似文献

林恩怀特争论始于怀特关于对基督教进行重新思考或者由非西方宗教取而代之的呼吁。林恩怀特争论已经被证明成为处理环境危机的一个障碍。由此而起的对基督教的辩护制约了亚洲和其他比较环境伦理学在西方的发展,没有产生对环境有益的结果。无论何时,当人们谈及宗教和环境的关系的时候,讨论都会迅速转向有关基督教对环境危机责任的讨论。这一争论的关键在于,怀特的论文在很多方面是对的:基督教的确在相当大的程度上造成了自然的世俗化,并且在中世纪,基督教在政治上对现在看来有害的人口增长的政策提供了支持,促进了科学和技术的发展,很多诸如此类的政策已经被证明对环境是有害的。但是,基督教还存在另一种对环境友好的传统,Assisi城的"圣芳济"运动就是其中一例,这种传统也许对于从环境角度重新认识基督教是有益的。但是,对于非西方国家环境伦理的发展,基督教将很难能够有所作为,非西方宗教也不大可能成功地在西方产生出某种环境伦理。因此,对于研究宗教的学者们而言,重要的是要走出谁应该为环境危机受到指责的争论,找到世界各主要宗教如何在其各自的文化范围内对发展环境伦理提供最佳帮助的方法。  相似文献

The concept of social capital reflects the norms and social relations embedded in the social structure of societies that enable people to coordinate community action to achieve desired goals. Our research focuses on the role that norms of cooperation and civic and political culture play in addressing the "digital divide" in computer use and Internet access. We review evidence from mail surveys of randomly selected respondents in two rural Minnesota communities as well as qualitative focus group and archival evidence suggesting that the communities have adopted different approaches to technology diffusion. Whether information technology is viewed as a public or private good depends in part on the civic culture of a community.  相似文献

The district of Kodagu, also called Coorg, in the Western Ghats of India produces 2% of the world's coffee, the expansion and intensification of which have reduced the forest cover by more than 30% in 20 years. Innovative actions are therefore urgently required to link economic development and biodiversity conservation, and stakeholders are exploring three strategies to add value to coffee from Coorg and prevent further biodiversity erosion: registration of trademarks; geographical indications; and environmental certification, via eco‐labels. This article analyses their respective strengths and weaknesses and discusses the synergies between them.  相似文献
