Based on a unique data set of Indian legislators and their behaviour during Question Hour over a 30-year period (1980–2009), the paper establishes that there is a substantial gap in the volume of questions asked by legislators from national and subnational parties, even after accounting for party size and other covariates. Thus, despite increasing subnational party prominence in the electoral and executive arenas, national parties dominate activities to do with legislative oversight. The paper also explores mechanisms that may explain the difference in legislative activity between national and subnational party legislators. 相似文献

Policy debates on strategies to end extremist violence frequently cite poverty as a root cause of support for the perpetrating groups. There is little evidence to support this contention, particularly in the Pakistani case. Pakistan's urban poor are more exposed to the negative externalities of militant violence and may in fact be less supportive of the groups. To test these hypotheses we conducted a 6,000‐person, nationally representative survey of Pakistanis that measured affect toward four militant organizations. By applying a novel measurement strategy, we mitigate the item nonresponse and social desirability biases that plagued previous studies due to the sensitive nature of militancy. Contrary to expectations, poor Pakistanis dislike militants more than middle‐class citizens. This dislike is strongest among the urban poor, particularly those in violent districts, suggesting that exposure to terrorist attacks reduces support for militants. Long‐standing arguments tying support for violent organizations to income may require substantial revision. 相似文献

The debate on citizen images of political parties is long standing, but recently it has taken on added importance as the evidence of party dealignment has spread across Western democracies. This article assembles an unprecedented cross-national array of public opinion data that describe current images of political parties. Sentiments are broadly negative, and this pessimism has deepened over the past generation. Then, we demonstrate how distrust of parties decreases voting turnout, contributes to the fragmentation of contemporary party systems and the electoral base of new protest parties, and stimulates broader cynicism towards government. Although political parties are the foundation of the system of representative democracy, fewer citizens today trust political parties, and this is reshaping the nature of democratic politics. 相似文献

The National Institute of Justice (NIJ) and the National Aeronautics and Space Administration's (NASAs) Goddard Space Flight Center (GSFC) have teamed up to explore the use of NASA developed technologies to help criminal justice agencies and professionals solve crimes. The objective of the program is to produce instruments and communication networks that have application within both NASA's space program and NIJ programs with state and local forensic laboratories. A working group of NASA scientists and law enforcement professionals has been established to develop and implement a feasibility demonstration program. Specifically, the group has focused its efforts on identifying gunpowder and primer residue, blood, and semen at crime scenes. Non-destructive elemental composition identification methods are carried out using portable X-ray fluorescence (XRF) systems. These systems are similar to those being developed for planetary exploration programs. A breadboard model of a portable XRF system has been constructed for these tests using room temperature silicon and cadmium-zinc telluride (CZT) detectors. Preliminary tests have been completed with gunshot residue (GSR), blood-spatter and semen samples. Many of the element composition lines have been identified. Studies to determine the minimum detectable limits needed for the analyses of GSR, blood and semen in the crime scene environment have been initiated and preliminary results obtained. Furthermore, a database made up of the inorganic composition of GSR is being developed. Using data obtained from the open literature of the elemental composition of barium (Ba) and antimony (Sb) in handswipes of GSR, we believe that there may be a unique GSR signature based on the Sb to Ba ratio. 相似文献

Two conflicting approaches to the study of group aggression are compared: the deindividuation theory of Zimbardo (1970) and
the emergent norm theory of Turner and Killian (1972). To test these two conflicting hypotheses, the frustration-aggression
theory of Brown (1986) is used which assumes that individuals and groups, male or female, will react with angry aggression
when important social justice norms are violated. It was hypothesized (i) that groups will be more aggressive than single
individuals; (ii) males will be more aggressive than females; and (iii) that more aggression will occur when people can be
easily identified than when they remain anonymous to each other. These hypotheses received some support. Unexpected interactions
between these variables are discussed in some detail. Generally, more support is found for the emergent norm theory than for
deindividuation theory. 相似文献

The present study examined the utility of a stress and coping model of adaptation to a homeless shelter among homeless adolescents. Seventy-eight homeless adolescents were interviewed and completed self-administered scales at Time 1 (day of shelter entry) and Time 2 (day of discharge). The mean duration of stay at the shelter was 7.23 days (SD = 7.01). Predictors included appraisal (threat and self-efficacy), coping resources, and coping strategies (productive, nonproductive, and reference to others coping). Adjustment outcomes were Time 1 measures of global distress, physical health, clinician- and youthworker-rated social adjustment, and externalizing behavior and Time 2 youthworker-rated social adjustment and goal achievement. Results of hierarchical regression analyses indicated that after controlling for the effects of relevant background variables (number of other shelters visited, sexual, emotional, and physical abuse), measures of coping resources, appraisal, and coping strategies evidenced distinct relations with measures of adjustment in ways consistent with the model's predictions with few exceptions. In cross-sectional analyses better Time 1 adjustment was related to reports of higher levels of coping resources, self-efficacy beliefs, and productive coping strategies, and reports of lower levels of threat appraisal and nonproductive coping strategies. Prospective analyses showed a link between reports of higher levels of reference to others coping strategies and greater goal achievement and, unexpectedly, an association between lower self-efficacy beliefs and better Time 2 youthworker-rated social adjustment. Hence, whereas prospective analyses provide only limited support for the use of a stress and coping model in explaining the adjustment of homeless adolescents to a crisis shelter, cross-sectional findings provide stronger support. 相似文献
