"Terrorism Studies" as a specific discipline is a comparatively recent addition to the social sciences and is still grappling with questions relating to a proper or appropriate methodology. This article argues that research within the field is often based neither on primary sources nor set within an independent analytical framework. Rather, it is characterized by an "aligned" position dependent on a research hermeneutic of crisis management, which perpetuates the "received view." Talking to "terrorists" and the use of social identity theory, applied in a context of cultural difference, are here proposed as a methodology enabling independent analysis. 相似文献

Historically, Disarmament, Demobilization, and Reinsertion (DDR) has provided a useful means to terminate conflicts. Since being catapulted to office in August 2002 with 53 percent of the vote of 46.45 percent of the voters, 1 Colombian President Álvaro Uribe has vigorously pursued a demobilization program, both individual and collective. However, despite the fact that over 40,000 combatants have demobilized under these programs, evidence is growing that this latest round of Colombian DDR is merely transitioning, rather than terminating, violence in that Andean country. 相似文献

Fathers’ patenting behavior and the propensity of offspring to patent: an intergenerational analysis
In this paper we show that the patenting behavior of innovators is correlated with the patenting behavior of their fathers. Our argument for exploring this relationship stems from established theories of entrepreneurial behavior, specifically theories on intergenerational behavior. Our empirical analyses are based on survey data collected from MIT’s Technology Review (TR) winners. 相似文献

In this study of perceived legitimacy, Australian citizens from a randomly selected national sample first responded to information about how judicial authorities responded to two crimes (green protest, date rape) in terms of seriousness and recommended punishment. They also provided ratings of the importance of a set of values for judicial authorities compared with self, and measures of global value discrepancy, procedural fairness, expertise, and legitimacy. Results showed that perceived legitimacy was negatively related to global value discrepancy and that the information provided to participants about judge’s position primed differences in value discrepancy only for the date rape crime. Other findings also implied that the nature of the offense moderated legitimacy/value discrepancy relations. Perceived legitimacy was also positively related to procedural fairness and the expertise of the authority, and higher when the judicial authority was perceived to assign specific values as even more important than participants did themselves. 相似文献

Objectives
Evaluate the use of various time series methods to measure the deterrence effect of capital punishment.Methods
The analysis of the time series approach to deterrence is conducted at two levels. First, the mathematical foundations of time series methods are described and the link between the time series properties of aggregate homicide and execution series and individual decision making is developed. Second, individual studies are examined for logical consistency.Results
The analysis concludes that time series methods used to study the deterrence effects of capital punishment suffer from fundamental limitations and fail to provide credible evidence. The common limitation of these studies is their lack of attention to identification problems. Suggestions are made as to directions for future work that may be able to mitigate the weaknesses of the current literature.Conclusions
Time series studies of capital punishment suffer from sufficiently serious identification problems that existing empirical findings are compatible with either the presence or the absence of a deterrent effect. 相似文献960.
Recent scholarship argues that how members of Congress respond to an ongoing war significantly influences the president's strategic calculations. However, the literature is comparably silent on the factors influencing the public positions members take during the course of a military venture. Accounting for both national and local electoral incentives, we develop a theory positing that partisanship conditions congressional responses to casualties in the aggregate, but that all members respond to casualties in their constituency by increasingly criticizing the war. Analyzing an original database of more than 7,500 content‐coded House floor speeches on the Iraq War, we find strong support for both hypotheses. We also find that Democrats from high‐casualty constituencies were significantly more likely to cast antiwar roll‐call votes than their peers. Finally, we show that this significant variation in congressional antiwar position taking strongly correlates with geographic differences in public support for war. 相似文献
