As the religious diversity of English towns and cities has grown over the past thirty years due to the establishment in some places of sizeable communities of Hindus, Muslims and Sikhs, as well as other faiths, there have been important changes to local public religion. Traditional civic ceremonies, such as Remembrance Sunday, as well as new forms of civic celebration and commemoration, are now increasingly taking account of the diversity of faiths represented in Britain. This paper examines the consequences of religious diversity for English civic religion by looking at some of the traditions of civic ceremonies in England and at the way in which they have been transformed by the changing religious landscape of towns and cities. The paper also explores some of the dilemmas and questions that have emerged both for the Church of England as well as for the other faith communities when it comes to the design and delivery of civic ceremonies. 相似文献

Factors affecting immediate serial recall of individual items can be classified according to whether they influence the degradation of the representation, or influence the ability to redintegrate a degraded representation. For recall of entire lists, factors can be classified according to whether or not they influence the rate at which items are recalled. We review experiments in order to classify the factors of serial position, word length, word frequency, and lexicality. We propose that the two classification systems coincide, at least for those factors whose classification is known for both schemes. We end by considering whether probability of recall of an entire list might be predicted from probability of recall of individual items. 相似文献

In this paper, I introduce and examine the notion of “mathematical engineering” and its impact on mathematical change. Mathematical engineering is an important part of contemporary mathematics and it roughly consists of the “construction” and development of various machines, probes and instruments used in numerous mathematical fields. As an example of such constructions, I briefly present the basic steps and properties of homology theory. I then try to show that this aspect of contemporary mathematics has important consequences on our conception of mathematical knowledge, in particular mathematical growth. 相似文献

Recruitment and Retention of Low‐SES Ethnic Minority Couples in Intervention Research at the Transition to Parenthood 下载免费PDF全文

Low‐SES couples have limited resources to manage the chronic and acute stressors with which they are disproportionately faced. Although these couples are at greater risk for negative individual and relationship outcomes, evaluations of the impact of couple relationship education (CRE) in low‐SES couples have been plagued by methodological problems, most notably challenges associated with recruitment and retention. We review the literature on challenges couples face associated with low‐SES, as well as on recruitment, retention, and CRE in low‐SES, ethnic minority populations. We illustrate some of these challenges in a case study of CRE for low‐SES couples transitioning to parenthood. In this pilot study, 21 couples were recruited from a community health clinic and randomized to either an experimental treatment condition (EXP; N = 11) or a treatment‐as‐usual control condition (TAU; N = 10). This study sought to mitigate documented challenges with recruitment and retention: We leveraged community partnerships, attempted to build and maintain strong relationships with study participants, provided incentives for assessments as well as intervention meetings, and attempted to reduce potential barriers to enrollment and retention. Nonetheless, we had low rates of recruitment and retention. We integrate these findings and experiences with our review of previous work in this area. We make recommendations for future CRE research and practice that have potential implications for public policy in this area. 相似文献

Relations between social comparison orientation and adjustment in Chinese adolescents: Moderating effects of initial adjustment status 下载免费PDF全文
This 1‐year longitudinal study examined relations between social comparison orientation (SCO) and socioemotional adjustment and academic achievement. A sample of Grades 7 and 8 students (N = 336, initial M age = 14.08 years) in China participated in the study. Data were collected from self‐reports, peer assessments and school records. It was found that early SCO positively contributed to later academic achievement. Moreover, the relations between early SCO and later socioemotional adjustment were moderated by the initial status of adolescents. Specifically, SCO was positively associated with social competence and negatively associated with depression in initially competent and well‐adjusted adolescents, but the pattern of the associations was opposite in initially incompetent and poorly adjusted adolescents. The results indicate that whereas SCO may contribute directly to academic achievement, its contributions to socioemotional development might depend on adolescents' initial status in adjustment. 相似文献

Two experiments were conducted to examine bidirectional semantic associations between power and weight using a priming paradigm. Bidirectionality in the relationship between power and weight was demonstrated, utilising tasks that were identical except that the orders in which the stimuli were presented were reversed. In Experiment 1, an empty scale leaning either leftward or rightward was used as a priming stimulus, and a scale that appeared in equilibrium with a pair of power words was used as a target stimulus. In Experiment 2, a scale with a pair of words that appeared in equilibrium was used as a priming stimulus, and an empty scale leaning either leftward or rightward was used as a target stimulus. We identified interaction effects between power and weight in both experiments. Associations between power and weight provide evidence for both conceptual metaphor views and evolutionary theory. The bidirectionality of metaphorical effects is in line with the strong version of metaphoric structuring. Both language and experiential correlations play important roles in the development of the mapping between power and weight. 相似文献

Negotiators more distanced from the negotiated goal more often exhibit integrative behavior, which maximizes both their individual and joint outcomes. Based on the assumption of an analogy between interpersonal negotiations and internal dialogs simulating social relationships, an experiment was carried out. It aimed to verify if psychological distance (proximal vs. distant perspective on the situation enacted in an internal dialog) affects the processes of integration and confrontation and, consequently, increases the frequency of integrative dialogs. Data from 115 participants (56 women) were analyzed. An increase in psychological distance was found to reduce the intensity of the confrontation process and to cause an increase in the number of integrative internal dialogs. 相似文献
