产业结构和所有制结构的差异--关于东西部地区经济增长差距的一种解释

改革开放以来 ,西部地区与东部地区经济增长的差距有越控越大的趋势 ,形成这些差距的一个重要原因是双方在产业结构和所有制结构上存在的差异 ,并从实证分析的角度进行了检验。     

略论东南亚华族的族群认同及其发展趋势

二战以后 ,东南亚华人的国家认同 ,逐渐从认同中国转为认同于当地 ;其族群认同也从认同于中华民族转为认同于华人族群。各国华人的族群规模、经济实力、凝聚力 ,以及当地国政府的华人政策的不同 ,其华人族群认同的发展过程和走势也各不相同。但总体趋势是融合于当地社会 ,或作为族群之一构成当地国家民族的组成部分 ,或是同化于当地主体族群。他们作为东南亚人 ,在今后很长时间中仍将保持强弱不等的华人族群认同的意识。     

Modelling data from single-photon emission computerized tomography

The completely random character of radioactive disintegration provides the basis of a strong justification for a Poisson linear model for single-photon emission computed tomography data, which can be used to produce reconstructions of isotope densities, whether by maximum likelihood or Bayesian methods. However, such a model requires the construction of a matrix of weights, which represent the mean rates of arrival at each detector of photons originating from each point within the body space. Two methods of constructing these weights are discussed, and reconstructions resulting from phantom and real data are presented.     

衰亡？抑或永恒存在？——现代美学语境中的悲剧走向

现代社会中的悲剧性主要体现在人性的异化方面,但是,无论传统悲剧理论还是现代悲剧观念,即对“悲剧性”的认识,在表现人的本质力量与人的生存困境、提高人的精神境界这些根本问题上,却大抵是一致的;悲剧从古典戏剧文体发展到现代美学范畴,是在美学家或艺术家面临现代型社会形态的困境时对感性生存的本体论位置的忧虑、对个体生存实践的自由意义的探索中出现的;人类历史的悲剧性、人生的悲剧性是永恒的,人类的悲剧意识、悲剧精神是永存的,那么作为人类生活审美化超越的艺术就不会失落悲剧的价值理想和追求。     

Reactions to Job Content Plateaus: Examining Role Ambiguity and Hierarchical Plateaus as Moderators

Plateauing research often reveals a negative relationship between job content plateauing (i.e., lacking challenge in one's job) and work attitudes. This study explores situations where job content plateauing is associated with fewer negative work attitudes, revealing role ambiguity (i.e., being unclear about job duties and responsibilities) and hierarchical plateauing (i.e., low likelihood of promotions) as moderators of the job content plateau‐work attitude relationship. Specifically, job content plateaued employees reported greater job satisfaction and organizational commitment if they were not also experiencing a hierarchical plateau. Job content plateaued employees also reported greater job satisfaction when role ambiguity was low.     

Between Spatial and Social Segregation among Immigrants: The Case of Immigrants from the FSU in Israel

Studies on immigrants' residential concentration have reported mixed findings. Some have argued that immigrants' residential concentration is a necessary step in the process of their social integration because there the newcomers find housing and employment opportunities as well as social support. As they learn the language and improve their socioeconomic status, they move to neighborhoods where they share space with the native population. Others have argued that the ethnic neighborhood delays the process of social integration in the new society because it nurtures informal ethnic social networks that provide incomplete information and retard the process of language acquisition. The study reported here investigated the effect of motivations, perceptions of attitudes of the host society, acculturation and socioeconomic factors on immigrants' residential concentration. It also sought to expand previous research by examining the relationship between immigrants'residential concentration and social relationships with nonimmigrants. Data for the study were collected in 1999 through a survey of immigrants from the FSU who had settled in one northern city in Israel after 1989. The results show a negative relationship of socioeconomic status and fluency in Hebrew with the percentage of immigrants residing in a given neighborhood. The higher the socioeconomic status and the more fluent the immigrant in Hebrew, the lower the percentage of immigrants in his or her neighborhood. Immigrants who expressed a proactive motivation for migration resided in neighborhoods with a low percentage of immigrants. Immigrants' residential concentration was not found to be related to the development of social relationships with the local population. The implications of the findings are discussed.     

Dealing with Toxicity in the Risk Society: The Case of the Hamilton,Ontario Plastics Recycling Fire*

Une perspective de la construction sociale sert de cadre a l'analyse des controverses sur la gestion des risques qui ont été provoquées à la suite d'un incendie majeur dans une usine de recyclage de matières plastiques à Hamilton, en Ontario. En mettant l'accent sur les processus de réclamation au c?ur de l'interaction entre les représen‐tants du gouvernement, les acteurs environnementaux, les experts techniques et les résidants, il a été révélé qu'un accent trop limité aux questions d'ordre technique avait mené a l'exclusion des préoccupations fondées sur la rationalité culturelle ayant ainsi entraine un cadre d'interaction très litigieux divisant profondément. Les conséquences des conclusions empiriques de la thése de la société des risques ainsi que de la théorie sur la communication des risques sont explorées. A social construction perspective is applied in the analysis of the risk management controversies that arose in response to a large toxic fire that occurred at a Hamilton, Ontario plastics recycling facility. By focussing on the claimsmaking processes involved in the interaction of government officials, environmental movement actors, technical experts, and residents, it was found that an overly narrow focus on technical matters led to the exclusion of lay concerns based on cultural rationality, thereby resulting in a very contentious and divisive setting for interaction. Implications of the empirical findings for the risk society thesis and risk communication theory are explored.     

Betrayal and repetition: Understanding aggression in sexually abused girls

Betrayal by a significant object is seen as primary in causing behavioral and emotional disturbances in incest victims, leading to a pervasive identification with the aggressor and disturbances in object relations development. Identification with the aggressor is understood not as a uniform defense mobilized against a specific affect but as a complex compromise formation which defends against anxiety, while also providing libidinal, aggressive and superego gratifications. Far from simply attempting to overcome the past, identifications thus preserve affects that have become pleasurable and self-defining. Two case studies of adolescent girls illustrate how treatment can help victims recognize and begin to forego the sadomasochistic pleasure derived from these identifications, a relinquishment necessary for true mastery.     

The Role of Cancer Risk in the Regulation of Industrial Pollution

The extent of carcinogen regulation under existing U.S. environmental statutes is assessed by developing measures of the scope and stringency of regulation. While concern about cancer risk has played an important political role in obtaining support for pollution control programs, it has not provided the predominant rationale for most regulatory actions taken to date. Less than 20% of all standards established to limit concentrations of chemicals in various media address carcinogens. Restrictions on chemical use are more frequently based on concerns about noncancer human health or ecological effects. Of the chemicals in commercial use which have been identified as potential human carcinogens on the basis of rodent bioassays, only a small proportion are regulated. There is an inverse relationship between the scope of regulatory coverage and the stringency of regulatory requirements: the largest percentages of identified carcinogens are affected by the least stringent requirements, such as information disclosure. Standards based on de minimis cancer risk levels have been established for only 10% of identified carcinogens and are restricted to one medium: water. Complete bans on use have affected very few chemicals. The general role that carcinogenicity now plays in the regulatory process is not dramatically different from that of other adverse human health effects: if a substance is identified as a hazard, it may eventually be subject to economically achievable and technically feasible restrictions.
