Abstract This paper describes a practical courtroom tool that provides insight in face recognition accuracy as a function of distance and illumination. Subjects were shown 3/4 target portraits with an exposition time of 12 seconds, immediately followed by a target-absent or target-present lineup of six full-face portraits. Subjects were asked to identify the target. Seven distances (3 to 40 meter) and nine illumination levels (0.3 to 3000 lux) were used which resulted in a 7?9 matrix, with in the cells a hit score and a false alarm score. From these rough data several other measures were derived, like d-prime, diagnostic value and some idealised scores. The scores represent the upper margins of recognition accuracy with the memory component reduced to a minimum. The results clearly indicate a systematic increase of recognition performance with decreasing distance and increasing illumination. The end result is a practical rule of thumb, the Rule of Fifteen: Even in ideal conditions the desired diagnostic value of 15 is reached at not more than 15 meters, not less than 15 lux. 相似文献

A review in the Journal of Peasant Studies by Reed [2003] of our book on indigenous movements and the state in Latin America provides a suitable opportunity to discuss several comments on questions raised in that text. In this rejoinder I argue that we do not judge neoliberalism a positive factor that provides indigenous peoples with a democratic space to press their demands. I show that our discussion of the neoliberal ‘cultural project’ provides the ground precisely for questioning the neoliberal brand of multiculturalism. Although the latter entails some degree of cultural affirmation, it simultaneously involves economic marginalization and disempowerment. This leads in turn to a further discussion of the relationship between indigenous movements and citizenship, and the strategy choices indigenous movements face in their pursuit of multicultural citizenship. 相似文献

This paper documents the functioning of the market in trade protection. It uses a narrative approach to demonstrate that politicians respond to the demands of special interests by forcing open foreign markets and by closing domestic markets. In the process government officials violate property rights, disregard economic logic, damage the world trading system, multiply rent-seeking costs, and destroy wealth. Such outcomes imply that there is a constitutional failure, and that the rules and institutions governing international trade need to be reformed. This paper discusses several such changes and considers how consumers could be mobilized to support them. 相似文献

Building on theories on new public management and results-based management, this article addresses performance measurement in comprehensive peace operations. More specifically it focuses on the Effects-Based Approach to Operations (EBAO) that is currently implemented by the International Security Assistance Force (ISAF) in Afghanistan to measure the performance on a wide range of areas such as security, governance, and socio-economic development. The article reveals and structures several key challenges in the complex measurement process, varying from technical (e.g., the lack of targets or benchmarks for an indicator) to fundamental ones (e.g., the large controversy between intuition-driven and assessment-driven leadership) and provides recommendations to meet these challenges. 相似文献

Whereas electoral support for new-rightist parties is often understood as driven by ethnocentric anti-immigrant sentiments, scholars have noted that new-rightist politicians have, surprisingly, stressed culturally progressive arguments in the last decade. Using recent Dutch survey data (N = 1,302) especially collected for this purpose, the article analyses the electoral relevance of three types of cultural progressiveness for voting for the new right and their relation to the well-documented anti-immigrant agenda. The analysis shows that neither moral progressiveness nor aversion to public interference of religious orthodoxy underlies the new-rightist vote. Support for freedom of speech proves relevant, but, in accordance with literature on the new right’s electoral strategy and with theorising on framing, this only leads towards the new right among those who are ethnocentric. These findings are discussed in the light of electoral competition, and questions for further research are formulated. 相似文献
