论沈从文小说性爱观照的价值尺度

大多现代作家在观照两性之爱时,往往以社会属性作为价值尺度,符合这种尺度是美,反之则恶.而沈从文却另辟蹊径,在性爱观照中取一种有别于有传统道德意图的价值尺度:以"生命"尺度肯定性爱的原始性;以"自然"尺度强调性爱的合理性;以"感情"尺度维护性爱的纯洁性.

‘Teaching should be observed’: a critical consideration of the issues involved in including teaching observation in the inspection of social work education

Social work education in England will have a new regulator from 2019. According to official sources, this is ‘as part of wider reforms to improve confidence in social work and raise the status of the profession’. In the background of any changes to social work education are the reports by Croisdale-Appleby (2014) and Narey (2014). Both reported that the existing regulatory regime was inadequate and made a combined total of 40 recommendations for improvement. Specifically, on the subject of social work teaching in higher education institutions, Narey expressed concern about both the content and quality and recommended that the teaching should be observed. If the incoming regulator were to introduce direct observations of teaching in inspections it would represent a new development. Previous regulators have not adopted this method. This discussion paper reviews selected literature on what teaching observation can and cannot achieve as an inspection method. It reflects on how social work education might gain if inspectors observed teaching. However, it also argues that to be a meaningful and credible process teaching observations need to take heed of a range of interrelated issues which, if not thought through properly, will invalidate the whole exercise.

Does Observed Conflict Recovery Play a Role in Adolescent Dating Aggression?

In a study of conflict recovery and adolescent dating aggression, 14- to 18-year-old couples (N = 209 dyads) participated in a 1-hr observational assessment. Negative behavior was observed during conflict-evoking “hot” tasks and in a “cooldown” task. Physical and psychological dating aggression were assessed via questionnaires. Negative behavior measured in the cooldown task was not associated with dating aggression after controlling for carryover effects of negativity from the hot to cooldown tasks. Moreover, cooldown negativity moderated the associations of hot task negativity and dating aggression. Actor and partner effects were disentangled via dyadic data analyses. Given the paucity of observational studies of dating aggression, our findings are an important contribution to the literature and in need of replication and extension.     

Strategies to handle the challenges of intimacy in night-time home care services

The provision of intimate and personal care constitutes a challenge for both careworkers and care recipients and is still a neglected area of research. An observational study of the interaction between the careworkers and care recipients in night-time home care services was conducted in a large municipality in Sweden. The results were analysed in light of previous research and theorising on strategies for handling intimacy in intimate care. The study highlights what appears to be a tension between the ways in which the recipient of care is conceptualised as an active consumer of care in present-day guidelines and the strategies chosen on the part of both caregivers and care recipients, when intimacy and integrity is most at stake, and framed as it is by the care recipients’ situation of dependency and vulnerability. Home care services night-time was shown to be a case that markedly differs from many other settings of intimate care, but in the interactional routines intimate care came forth as a smooth and minimally obtrusive activity. The careworkers and care recipients engaged in strategies such as disattention, eye-discipline, middle-distance orientation, and objectification, thereby serving the purpose of balancing the transgressions of thresholds of intimacy.
