This study investigates the pupal development times of the blow fly Calliphora vicina, which were studied in the laboratory at six different constant temperatures (15, 20, 23, 25, 28, and 30°C each ± 1°C). Lower thresholds (tL) for development were estimated from the linear regression of the developmental rates on each temperature. These data have made it possible to calculate the accumulated degree days (ADD) necessary for C. vicina to complete the larval stage and to achieve adult emergence. The minimal duration of development from oviposition to adult emergence was found to be inversely related to temperature. Additionally, six landmarks in pupal development are showed, and for each of the landmarks, the ADD value was calculated for every rearing temperature involved. These data assist in calculating the duration of the pupal stage based on morphological characteristics and would be of great value for future forensic entomological casework.  相似文献

Despite rapidly increasing global flows of international students, research to date has paid little heed to how students abroad identify and mobilise. Focusing on the experience of Indonesians, Malaysians and Singaporeans in Australia – a primary hub for international education – we explore the ways in which our informants understand their place and potential as students. We find international students to comprise a distinct sort of diaspora. With their liminal status, these – for the most part – only temporary transnationals do internalise new norms and agency in a personal sense. However, they tend to identify increasingly as national citizens and to be disinclined to mobilise politically, at least during the course of their studies. These findings add to our understanding both of collective identity and action among students, and of the broader implications of globalisation and internationalisation for social and political activism.  相似文献

This paper analyzes attitudes of women enrolled in secular and religious universities in the capital cities of Kyrgyzstan and Tajikistan toward family life and the role of Islam in the private and public sphere. Survey data indicate that women from both types of universities in both countries sympathize with retraditionalization, or “a return to traditional values, family life, and religion, which entails, in part, women being moved out of the work force.” Thus far, there is no statistical evidence of this phenomenon in the literature. Sympathy for retraditionalization is unfolding in the context of ongoing economic uncertainty that has plagued Kyrgyzstan and Tajikistan since the Soviet Union's collapse, and its manifestations produce political responses. I argue that Kyrgyz and Tajik elites push a particular gender norm implying female secularization to counter expressions of retraditionalization among young women. In conclusion, I highlight counterintuitive findings of the survey regarding Islam's role in Central Asian society and discuss collective versus individual acts of resistance to female secularization policies in Kyrgyzstan and Tajikistan.  相似文献

The prospect of transatlantic cooperation in the field of defence systems depends on reaching an acceptable point of equilibrium. Without it, Europe will face the unacceptable strategic, political, economic and industrial risks of total American predominance in this field (with the consequent loss of technical and production expertise). The reduction of the gap between Europe and the United States depends on the integration of the European defence market. This must not be seen as a threat for transatlantic collaboration, but as an opportunity. Building up a transatlantic market could also improve the efficiency of the American market by increasing competition. This collaboration, based not on bilateral, national or multilateral agreements, but on bi-continental cooperation, is the challenge that Europe and the United States must face and meet together.  相似文献

In the Tourist-Caronte case in Italy, the incumbent, Tourist-Caronte,reacted to entry by entrant Diano by starting to supply a "damagedgood" in the sense theorized by Deneckere and McAfee in 1996.We argue that in principle this strategy can be predatory, butit can also be an innocent response to entry. Specifically,the strategy of damaging the good leads to fiercer competitionin the low segment of the market, which reduces the rents thatthe incumbent earns in the high segment, but may allow the incumbentto steal some of the entrant's rents. If this business stealingeffect in the low segment of the market is sufficiently strong,the incumbent may find it profitable to expand its product lineafter entry, even if it does not have any predatory intent.We discuss the welfare effects of this strategy, and we contrastit with predation.  相似文献

For a number of reasons, researchers and policy makers are now focusing on diversion of youth from the juvenile justice system. This study examines New York State's diversion efforts focused on youth with mental health and substance abuse problems who are at risk of out-of-community placement (N = 2,309). Twelve counties participated in the Mental Health Juvenile Justice (MH/JJ) Diversion Project. Overall, the initiative was successful in reducing out-of-community placement and recidivism for diverted youth. In regression analysis site, services received, and problem-profile variables were important predictors of out-of-community placement. Prior record, prior placement, and significant mental health problems were statistically significant predictors of recidivism. This suggests some contrasts in explaining the results of two important goals of the MH/JJ project. Study results and implications for future research and intervention are discussed.  相似文献

This study extends past research by examining predictors of different types of sexual assault perpetration in a community sample. Computer-assisted self-interviews were conducted with a representative sample of 163 men in one large urban community. As hypothesized, many variables that are significant predictors of sexual assault perpetration in college student samples were also significant predictors in this sample, including empathy, adult attachment, attitudes about casual sex, sexual dominance, alcohol consumption in sexual situations, and peer approval of forced sex. For most measures, the strongest differences were between nonassaulters and men who committed acts that met standard legal definitions of rape. Men who committed forced sexual contact and verbal coercion tended to have scores that fell in between those of the other two groups. The implications of these findings are discussed for community-based sexual assault prevention programs.  相似文献

The past decade has witnessed a growing interest among scholars of international relations, and global environmental governance in particular, in the role of transnational networks within the international arena. While the existence and potential significance of such networks has been documented, many questions concerning the nature of governance conducted by such networks and their impact remain. We contribute to these debates by examining how such networks are created and maintained and the extent to which they can foster policy learning and change. We focus on the Cities for Climate Protection (CCP) program, a network of some 550 local governments concerned with promoting local initiatives for the mitigation of climate change. It is frequently asserted that the importance of such networks lies in their ability to exchange knowledge and information, and to forge norms about the nature and terms of particular issues. However, we find that those local governments most effectively engaged with the network are mobilized more by the financial and political resources it offers, and the legitimacy conferred to particular norms about climate protection, than by access to information. Moreover, processes of policy learning within the CCP program take place in discursive struggles as different actors seek legitimacy for their interpretations of what local climate protection policies should mean. In conclusion, we reflect upon the implications of these findings for understanding the role of transnational networks in global environmental governance.  相似文献

Two studies examined reactions of family members to supervised access (SA) services. In Study 1, 121 users of SA services were interviewed about their satisfaction. A subsample was interviewed about family relationships and children's well-being, at Time 1 and 5 months later. In Study 2, 29 children attending SA services were interviewed. Results showed that both custodial and noncustodial parents were very satisfied with the centers. There was no evidence that relationships between ex-spouses or their attitudes toward one another improved over a 5-month period. Children attending centers showed a high level of externalizing symptomatology. Children were positive about their experiences, although older children felt that the centers were not well equipped for their age group. Although the aim of centers is to provide a safe place for children, some children still experience emotionally disturbing events. Most children had little understanding about why they were attending centers.  相似文献

How do political identities shape seemingly non-political behaviors, such as consumption activity? This paper explores the extent to which political divisions impact apolitical behaviors, focusing on the case of voluntary donations to charitable organizations. Drawing on recent work showing partisans’ differing use of “conspicuous consumption,” we develop and test expectations as to how charitable activity may differ for Democrats and Republicans. Using three national surveys, including an original two-wave panel study, we find sizable differences in overall giving between partisans, with Republicans giving more to charity on average. We show that partisan differences in religiosity, and not differences in beliefs about government spending or desires to signal economic status, explain partisan gaps in giving. Our findings contribute to our understanding about the broader consequences of political fragmentation in the United States and provide further evidence for the social, as opposed to ideological, roots of political identity.  相似文献
