In the UK, the Joint Intelligence Committee (JIC) has a poor track record of predicting attack. In the US, official inquiries into 9/11 identified ‘a failure of imagination’ to conceive of a large scale threat to the American homeland. There is a long-standing literature on surprise attack which emphasizes that clues to predict attack often exist but are not pieced together by an intelligence sector which is not structured to look in the right direction. In a world of increasingly fragmented threats and weak signals, it is apparent that much of the challenge in intelligence work now lies not in collection but in managing requirements, setting priorities, and conducting incisive analysis based on the ability to imagine new threats. One solution to a failure of imagination is to widen the range of people who can contribute to the task. Non-Governmental analysis of security issues, whether by academia, civil society or the private sector, can help to identify emerging issues and set priorities. Whilst collection of secret intelligence may always remain the preserve of specialist Government agencies, the rest of the intelligence cycle can benefit from external contributions and open source intelligence. We argue that the process of setting intelligence requirements could be opened to a wider range of actors. In conflict environments, there may be particular value in an open process to identify what each side would need to know about the other to confidently seek peace.  相似文献

Classical test theory approaches to measurement are based upon a number of fairly restrictive assumptions. The nature of these assumptions is such that scales designed to operationalize latent constructs are treated with little regard for the interaction between the human subject and the items that compose the measurement scale. A competing measurement approach, the Rasch model, has been advanced to improve upon the limitations of classical test theory. In this article, the Rasch model was applied to a scale designed to measure Tittle's control balance ratio. Analysis suggests that the original scale and response category options do not meet fundamental measurement. In particular, several items exhibited misfit (and were thus removed from the scale), response category options were reduced from eleven to four, and the scales that form the control balance ratio exhibited very little gender bias. An alternative control balance scale that retains the original items is presented, but this scale no longer summarizes the control balance ratio as one overall score. The implications of these results are addressed.  相似文献

So far we have little by way of a theoretical understanding of the dynamics of electoral competition. This paper attempts to fill some of this gap by studying resource expenditure over the electoral cycle. Among the main results is that, when contributions from donors are independent of support, parties accelerate expenditure during the entire period between elections, even when voters do not forget. If contributions depend on support, and are significant, parties front load expenditure and decelerate.  相似文献

Research had consistently shown that intimate partner homicide rates had been on a steady downward decline over the past two decades; however, a relatively recent movement in intimate partner homicide research had emphasized the need for further dissecting the aggregate trends by factors such as gender, race, victim-offender relationship, and same-sex partners. Taking this a step forward, this study utilized trajectory analysis for comparing and contrasting non-intimate partner homicide and intimate partner homicide rates over time in order to explore the importance of rurality when investigating intimate partner violence. Results of the analysis indicated that although intimate partner homicide rates had been declining over the 1980-1999 period for the majority of the 1,341 U.S. counties examined, there was evidence that rurality was significantly associated with an increased likelihood of assignment to a non-declining intimate partner homicide trajectory. In light of the findings, the authors also consider how these results can direct future research on intimate partner violence in rural areas.  相似文献
