Good survey and experimental research requires subjects to pay attention to questions and treatments, but many subjects do not. In this article, we discuss “Screeners” as a potential solution to this problem. We first demonstrate Screeners’ power to reveal inattentive respondents and reduce noise. We then examine important but understudied questions about Screeners. We show that using a single Screener is not the most effective way to improve data quality. Instead, we recommend using multiple items to measure attention. We also show that Screener passage correlates with politically relevant characteristics, which limits the generalizability of studies that exclude failers. We conclude that attention is best measured using multiple Screener questions and that studies using Screeners can balance the goals of internal and external validity by presenting results conditional on different levels of attention. 相似文献

Abstract The Crisis Intervention Team (CIT) model is an established training program used to improve police response to encounters involving persons with mental illness (PwMI). Diversion of PwMI from the criminal justice system to appropriate treatment providers in the community is one of the primary goals of CIT. The present study examines characteristics and outcomes of encounters between citizens experiencing mental health-related crises and CIT-trained patrol officers. Findings of this study indicate encounters involving PwMI and CIT-trained officers often result in diversion to mental health services. Implications for policy and future research are discussed. 相似文献

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
