Chemical Accidents in the United States, 1990–1996

Objective. Much of the empirical work on environmental justice centers on the geographic distribution of potential chronic health risks (e.g., planned toxic releases or treatment storage and disposal facilities). Far less attention has been devoted to the geographic distribution of acute health risks that cause immediate harm. The purpose of this work is to examine environmental justice in terms of potential acute health risks by examining the distribution of serious chemical accidents across diverse subpopulations. Methods. We draw upon 1990 census data for the United States to study the relationship between the racial, ethnic, and economic characteristics of census block groups ( N = 226,398) and the presence or absence of chemical accidents that caused at least one injury, death, or evacuation for the time period of 1990–1996. The data used to map the location of the chemical accidents were obtained from the Environmental Protection Agency's Accidental Release Information Program (ARIP) database. Results. Our results indicate that the acute risk associated with chemical accidents at fixed facilities is greater for individuals living in low–income census block groups, especially when comparisons are made within the counties where the chemical accidents occur. Our results concerning race and ethnicity are less consistent and somewhat weaker. Conclusions. Although these results do not show large and dramatic effects, as have often been found in the study of the social distribution of chronic environmental risk, they do stand as one of a relatively few social analyses of social variation in exposure to acute environmental risk.     

全球经济及其理论辨析

由关贸总协定、世界贸易组织、世界银行、欧共体、美洲自由贸易区等国际协定和跨国公司体现的世界经济一体化是由私有化进程和打破区域垄断的自由主义经济目标推动的不可逆转的趋势。在这一过程之中经济和经济学成了世界的结构信息。经济学的两个预设———自私自利的经济人和人的世界———非人世界的二元论是全球经济的深层理论基石。经济人的实践活动造成贫富不均 ,二元论把人溺爱成肆无忌惮地破坏环境的动物。人类应该冷静思索这一新的世界形势 ,提出合理对策

Social workers' perceptions of their power and service outcomes

While social workers are becoming increasingly interested in methods of client empowerment, little attention has yet focused on the links between workers' own power and the services they provide to clients. The authors examine the link between workers' perceptions of their power on the job and perceived service outcomes. Bivariate and multivariate analyses were conducted on survey responses from 591 direct practice social workers in Israel. Results indicate that power perceptions are significantly associated with an array of perceived service outcomes. These findings highlight the relevance of self-efficacy and control theory in understanding social workers' efforts toward effective service delivery. Further, they underscore a need to consider more carefully direct practitioners' own power concerns as they increasingly consider empowerment of their clients.     

Trilateral Labour Markets, Pricing and the Demand for Personal Social Services

Correspondence to Dr B. Burkitt, Department of Social and Economic Studies, University of Bradford, Bradford, West Yorkshire, BD7 1DP. Summary The authors examine recent trends in labour markets and employmentexperience, which have altered significantly the socio-economiccharacteristics of social work clients. They argue that thesechanges have reduced the relevance of proposals for the increaseduse of pricing and the introduction of vouchers in the provisionof personal social services. The needs of clients are unlikelyto be met by a further concentration of analytical attentionon such largely unworkable proposals.     

On the emptiness of the stability set of order d

We know from Li's theorem (1993) that the stability set of order d may be empty for some preference profiles. However, one may wonder whether such situations are just rare oddities or not. In this paper, we partially answer this question by considering the restrictive case where the number of alternatives is the smallest compatible with an empty stability set. More precisely, we provide an upper bound on the probability for having an empty stability set of order d for the majority game under the Impartial Weak Ordering Culture assumption. This upper bound is already extremely low for small population and tends to zero as the number of individuals goes to infinity.     

When Are Net Effects Gross Products? Communication

The rush to judgment about the social effects of the new communications media has branded them as positive and negative in equal measure. Alienation from "real world" relationships coupled with a lack of social regulation within the medium is balanced by liberation from the influences, inequalities, and identities to which people are subjected in face-to-face interaction. We argue that such general conclusions may in fact be turned upside down and propose that these media may actually strengthen social bonds but also reinforce power inequalities. Reviewing evidence of our research with university students, employing the social identity model of deindividuation effects, we show how these technologies can often be more "social," and socially regulated, than face-to-face interaction.
