Several aspects of the incivilities thesis, or the role of social and physical disorder in encouraging crime and fear, deserve further testing. These include examining individual- and streetblock-level impacts on reactions to crime and local commitment over time, and testing for lagged and co-occurring impacts at each level. We model these four types of impacts on three reactions to crime and community satisfaction using a panel study of residents (n = 305) on fifty streetblocks, interviewed two times a year apart. At the individual level, incivilities showed unambiguous, lagged impacts on satisfaction, fear, and worry; furthermore, changes in perceived incivilities accompanied changes in resident satisfaction and fear. At the streetblock level: incivilities failed to demonstrate expected lagged impacts on either of the two outcomes where data structures permitted such impacts; changing incivilities, however, were accomp-anied by changing community satisfaction and changing perceptions of relative risk. Before we conclude that lagged ecological impacts of incivilities are weaker than previous theorizing suggests, we must resolve some outstanding theoretical and methodological issues. 相似文献

ABSTRACT Japan accounts for nearly 52 percent of the world's share of operational robots and leads the postindustrial world in the development of humanoid robots designed and marketed specifically to enhance and augment human society. Innovation 25, Prime Minister Abe's visionary blueprint for remaking Japanese society by 2025, with the aim of reversing the declining birthrate and accommodating the rapidly aging population, emphasizes the central role that household robots will play in stabilizing core institutions, like the family. In addition to exploring the cultural logic behind the development of autonomous, intelligent, evolutionary humanoid robots, I argue that new bio-and robot technologies are being deployed to reify old or “traditional” values, such as the patriarchal extended family and sociopolitical conservatism. 相似文献

One of the most common yet understudied means of suppressing free expression on college and university campuses is the theft of freely distributed student publications, particularly newspapers. This study examines news accounts of nearly 300 newspaper theft incidents at colleges and universities between 1995 and 2008 in order to identify the manifestations and consequences of this peculiar form of censorship, and to augment existing research on censorship and tolerance by looking, not at what people say about free expression, but at what they do when they have the power of censorship in their hands. Among the key findings is that men commit nearly 70% of newspaper thefts, which is inconsistent with much of the existing research on censorship and gender, and that those who censor college newspapers are far more concerned with their own self-preservation than with shaping public dialog on controversial social or political issues. 相似文献

Post-traumatic stress symptoms, depressive symptoms, and psychological dysregulation have been shown to mediate the relationship
between child maltreatment and non-suicidal self-injury. However, these proposed mediators often co-occur and previous research
has not tested mediation when all variables are assessed simultaneously. The current study sought to advance the literature
on maltreatment and self-injury by estimating the mediational effects of post-traumatic stress symptoms, depressive symptoms,
and psychological dysregulation in the same multiple mediator model. Both maltreated (n = 129) and non-maltreated (n = 82) adolescent females, consisting of Caucasian (55%), African-American (37%), and Bi-racial (8%) backgrounds, participated
in the study. Results indicated that only post-traumatic stress symptoms mediated the relationship between maltreatment and
self-injury when all variables were included in the model. Overall, post-traumatic symptoms represented a unique pathway from
maltreatment to self-injury and warrant special attention when assessing and treating such behavior with adolescent females. 相似文献
