After introducing a perspective on terrorism as postpolitical and after establishing the criteria for success that are immanent in this form of antipolitical action, this essay interprets September 11, 2001, and its aftermath inside a cultural‐sociological perspective. After introducing a macro‐model of social performance that combines structural and semiotic with pragmatic and power‐oriented dimensions, I show how the terrorist attack on New York City and the counterattacks that immediately occurred in response can be viewed as an iteration of the performance/counterperformance dialectic that began decades, indeed centuries, ago in terms of the relation of Western expansion and Arab‐Muslim reaction. I pay careful attention to the manner in which the counterperformance of New Yorkers and Americans develops an idealized, liminal alternative that inspired self‐defense and outrage, leading to exactly the opposite performance results from those the al‐Qaeda terrorists had intended .  相似文献

Behavioral observation is widely used for data gathering in evaluation research. Yet it leaves the investigator with unique problems. Usually, multiple observations result in a hierarchical data set, where numerous data records exist for each subject. Researchers face data reduction problems at least at two levels. First, there is the well-known and often-addressed problem of reducing the number of variables in a data set with only one information record per individual. Second, there is the problem of summarizing data at the individual subject level. The easiest way to perform this latter type of aggregation involves using univariate summary measures as probabilities of “using” an item, means, or standard deviations for each item per subject. Other standard procedures include first order interactions between pairs of items. However, use of pair-wise interactions is restricted because of variable dependence within each subject (this Affects e.g. factor analysis), or because of the relatively high number of single observations (this Affects e.g., cluster analysis). In this paper we propose employing Latent Class Analysis (LCA) to reduce the amount of information in observational data sets. In a first step, LCA allows one to specify intraindividual behavior patterns. In a second step, LCA allows one to derive meaningful summary scores for each individual. The two steps are illustrated using data that describe peer play competence in Swedish toddlers.  相似文献

The issue of transracial adoption has been a controversial issue in foster care and adoption placement decisions. In 1994, the 104th Congress passed the Multiethnic Placement Act (MEPA), forbidding agencies receiving federal funds from solely considering race, culture, and ethnicity in making foster care and adoption placement decisions. Congress mandated that the Department of Health and Human Services (DHHS) develop policy guidelines for child placement agencies to follow. In April 1995, DHHS issued the guidelines that agencies were to follow. The authors of the paper discuss the MEPA, DHHS's policy guidelines for agencies and the guidelines' legal support, and the implications for social work practice in foster care and adoption placements.  相似文献

This paper examines the existence of strategic solutions to finite normal form games under the assumption that strategy choices can be described as choices among lotteries where players have security- and potential level preferences over lotteries (e.g., Cohen, Theory and Decision, 33, 101–104, 1992, Gilboa, Journal of Mathematical Psychology, 32, 405–420, 1988, Jaffray, Theory and Decision, 24, 169–200, 1988). Since security- and potential level preferences require discontinuous utility representations, standard existence results for Nash equilibria in mixed strategies (Nash, Proceedings of the National Academy of Sciences, 36, 48–49, 1950a, Non-Cooperative Games, Ph.D. Dissertation, Princeton University Press, 1950b) or for equilibria in beliefs (Crawford, Journal of Economic Theory, 50, 127–154, 1990) do not apply. As a key insight this paper proves that non-existence of equilibria in beliefs, and therefore non-existence of Nash equilibria in mixed strategies, is possible in finite games with security- and potential level players. But, as this paper also shows, rationalizable strategies (Bernheim, Econometrica, 52, 1007–1028, 1984, Moulin, Mathematical Social Sciences, 7, 83–102, 1984, Pearce, Econometrica, 52, 1029–1050, 1984) exist for such games. Rationalizability rather than equilibrium in beliefs therefore appears to be a more favorable solution concept for games with security- and potential level players.   相似文献

Foreword     
This article charts the history of MuseumAfrica (formerly the Africana Museum) from its founding vision to the present. Taking the museum’s current abysmal reputation as its starting point, it seeks to fill the void in academic and popular thought that encompasses the institution. Sketching the original mandate under which it was created before focusing on the museum’s work from 1935 to the near present, it explores the ways in which the museum interacted with and impacted the world outside its doors. Paying particular attention to the museum’s engagement with liberal and illiberal forces for change, it presents the museum as something other than the monument impervious to change that it is often assumed to be. Categorising the museum as an archive, this article argues in favour of the museum’s enduring relevance in the post‐colonial order.  相似文献

Ethnic differences in demographic behavior tend to be disguised behind analytically opaque labels like “district” or “region,” or else subjected to simplistic cultural explanations. Drawing on new political economy, sociological theory and the political science literature on sub‐Saharan Africa, this article proposes an alternative explanatory model and tests it empirically with reference to Kenya. Access to political power and, through power, access to a state's resources—including resources devoted to clinics, schools, labor opportunities, and other determinants of demographic behavior—are advanced as the key factors underlying ethnic differences. District‐level estimates of “political capital” are introduced and merged with two waves of Demographic and Health Survey data. The effects on models of contraceptive use are explored. Results confirm that measures of political capital explain residual ethnic differences in use, providing strong support for a political approach to the analysis of demographic behavior.  相似文献

Objective. Immigration scholars have found that the highly educated and political liberals are considerably less likely to support restrictionist immigration policies than other groups. I ask whether the influence of social desirability pressures in the survey interview is responsible for this finding. Methods. An unobtrusive questioning technique known as the list experiment is used to measure Americans' support for immigration restrictionism. The list experiment can easily be embedded in a standard telephone survey and has been used by previous investigators to study racial attitudes. Results. Restrictionist sentiments are found to be more widespread among the U.S. populace than previous studies have estimated, especially among college graduates and political liberals. Conclusion. My findings have implications for immigration scholars and social scientists who study other sensitive attitudes and behaviors. The most commonly employed strategies to reduce socially desirable responding may not be enough.  相似文献
