从"权利"到"仪式":南非的艾滋病行动主义

在本文中,我考察了南非HIV/AIDS行动主义的道德政治如何有助于公民身份(citizen-ship)新形式的出现,这种新形式既与基于权利(rights-based)的斗争相关,又与个体HIV/AIDS患者对病痛和污名化(stigmatization)极端体验的共享意义相关。我指出,可以确定的是,正是晚期艾滋病患者"接近死亡"的绝境体验、以及与这种疾病晚期阶段相连的巨大污名和"社会死亡",为HIV/AIDS的幸存者对"新生命"和社会行动主义的委身提供了平台。行动主义者的干预和对这些创伤经验的重述也推动了HIV/AIDS对行动主义的委身和社会底层的动员。此外,污名和社会死亡的巨大否定性也驱使行动主义者重建对HIV检测呈阳性人群新的、正面的身份认同,并促使他们思考,作为一名公民-行动主义者和一项社会运动的成员意味着什么。     

Maximal autocorrelation functions in functional data analysis

This paper proposes a new factor rotation for the context of functional principal components analysis. This rotation seeks to re-express a functional subspace in terms of directions of decreasing smoothness as represented by a generalized smoothing metric. The rotation can be implemented simply and we show on two examples that this rotation can improve the interpretability of the leading components.     

Migration Decisions of Dual-earner Families: An Application of Multilevel Modeling

A comprehensive framework for guiding analyses of internal migration is lacking. This study contributes to the family migration literature in three important ways. We develop a multilevel theoretical framework emphasizing an integration of individual-, family-, and neighborhood-level effects; introduce multilevel statistical modeling; and explicitly assess how effects of economic-based explanatory variables vary by gender. Our data are from the Panel Study of Income Dynamics (PSID). We find that the likelihood of a family migrating is affected by economic and non-economic factors, some of which vary by gender. We add to the dual-earner migration literature by finding that wives are not likely to be tied-movers, but husbands are likely to be tied-stayers. Neighborhood factors also are important to the decision to migrate.

The Continuing Legacy of the Communist Legacy? The development of family policies in Poland and the Czech Republic

This article compares family policies in Poland and the CzechRepublic in order to explain why the two countries have differentpolicies. Previous studies are right to claim that post-communistfamily policies are basically going in a refamilialist directionthat gives mothers a greater incentive to return to the home,but they tend to neglect the important differences that existbetween countries. Although previous studies were correct toemphasize the role of the anti-feminist communist legacy inexplaining this trend toward re-famialilization, it is a country'seconomic-institutional legacy that goes the farthest in explainingthe differences in policies.     

FEAR,ANGER, AND CREDIT. ON BANK ROBBERIES AND LOAN CONDITIONS

We study the impact of emotions on real-world decisions made by loan officers by analyzing the loan conditions of loans granted immediately after a bank branch robbery. We find significant differences between the conditions of loans granted after a robbery and changes in loan conditions that occur contemporaneously at unaffected branches. In general, loan officers seem to adopt so-called avoidance behavior. In accordance with the literature on posttraumatic stress, their avoidance behavior is halved within 2 weeks following the robbery and the effect further varies depending on the presence, or absence, of a firearm during the robbery.

On Sampling Error in Market Share Estimates*

The relative error in the usual estimator of a brand's market share is reformulated in terms of marketing parameters. Such error is shown to be influenced in an important way by market penetration, as well as by variation in brand and product category volume. Of particular interest is the result that the relative error does not depend on the actual share level. Using data from a marketing research firm that supplies share estimates to the health products industry, we find that the relative error may be substantial even when a large sample is available. An upper bound on this relative error is obtained using marketing parameters that can frequently be measured using industry data and a company's internal records, thus reducing the level of judgmental input required in the planning of sample surveys.
