从胡文化“汉化”看生态环境的迁移对文化转型的影响

不同文化特质的形成 ,除受政治经济影响外 ,还受特定生态环境的制约。胡汉两大文化体系的差异 ,在很大程度上就是不同生态环境作用的结果。与此相应 ,文化的发展一旦脱离了与自身相适应的环境 ,就势必要出现势能上的劣势 ,并逐渐与异地文化相溶     

Current and Future Problems of Capital Accumulation in the Chinese Pension System

The decree establishing a uniform system of basic pensions for employees in municipal and private enterprises, published by the State Council on 16 July 1997, reflects the Chinese Government's ultimate choice in favour of a partly private funded scheme to cover future pension needs. This article examines the reasons which led to this choice and asks how easy or otherwise it will be to find the capital to finance it. The authors believe that the partly private scheme is more advantageous than other methods and is right for China. Many issues, however, remain the focus of lively debate. In particular, a realistic coordination of individual and group accumulation is needed in order to avoid shortfalls in capital formation and the dangers of inadequate benefit provision. To safeguard the subsistence needs of former workers in state-owned enterprises, a system of equalization at national level is needed, and problems continue over how future pension insurance funds should best be managed.     

Brand management: Unveiling the delusion of control

Mainstream brand management literature views brands as products or organisations carrying brand names and brand managers as being in control of brand-related actions and outcomes. By contrast, recent empirical research shows the substantial influence of stakeholders on brands. Together with brand management, stakeholders shape brands by participating in brand-related interaction. European brand research accordingly treats brands as ongoing and complex processes in constant flux. Nevertheless, literature suffers from a significant lack of theoretical underpinnings for understanding brands as complex processes; in this respect, building on European philosophy is a fruitful avenue. This paper introduces the metaphor of the rhizome and draws on European process philosophy to further develop an integrative processual understanding of brands. Brand management claiming control over brands as processes turns out to be a delusion.     

Information Needs Concerning a Planned Waste Incineration Facility

Waste management has become a major environmental issue in Germany. The siting of waste incineration especially arouses strong local opposition. The study presented here is related to such a case (i.e., a planned waste incineration facility in a small West German village). The study is based on a telephone survey aimed at the information needs of the residents. Two topics are stressed: (1) the thematic relevance of the siting project as seen by the public; and (2) the residents'information needs. The results show that a majority of residents are concerned about the planned facility, and the most important topics of their information needs refer to the risks and the safety systems of the planned facility, as well as information about waste management alternatives. Furthermore, the information needs depend on the personal relevance of the issue and the perceived knowledge deficit about it. Conclusions are drawn with regard to the design of a risk communication program. Here, four groups of residents are distinguished in terms of knowledge and motivation and, thus, need to be approached in different ways.     

Schulverweigerung

The aim of this article is to describe the extent of truancy in Cologne and to identify the relevant predictors. Hypotheses are deduced from classical deviance theories (control theory, amomy theory, theory of urban subcultures) and tested empirically. Our analysis is based on a survey of pupils in Cologne from grade 8 to 10 which was conducted in 1999 by the Max Planck Institute for Foreign and International Criminal Law in Freiburg. Our results show that 7.9 percent of all respondends can be defined as truants. Boys play truant more than girls, and the higher the age, the more pupils bunk off school. More important than gender and age is the type of secondary school. We find the highest amount of truants at Hauptschulen and Sonderschulen. It is shown that truancy is a multidimensional phenomenon that cannot be explained by just one single theory.     

Comparing three alternative types of employment with permanent full-time work: How do employment contract and perceived job conditions relate to health complaints?

Previous research has found that alternative employment arrangements are associated with both impaired and improved well-being. Since such inconsistencies are likely to derive from the type of employment contract as well as the characteristics of the job, this paper compares permanent full-time work with forms of alternative employment (permanent part-time, fixed-term and on-call work) in order to investigate how different employment contracts and perceptions of job conditions relate to individual well-being. This study contributes to the literature by addressing several questions. Different forms of alternative employment are distinguished and individual background characteristics that might be intertwined with the employment contract are controlled for. Moreover, the scope of this study extends to the effects of perceived job conditions, and possible interactive effects with type of employment are tested. Analyses of questionnaire data from 954 Swedish healthcare workers show that perceptions of the job (job insecurity, job control and demands), but not the type of employment contract, predicted health complaints. However, type of employment interacted with perceptions of job insecurity, in that insecurity was associated with impaired well-being among permanent full-time workers, while no relationship was found for on-call or core part-time employees. Despite the absence of interactions between employment contract and job demands or job control, it can be concluded that knowledge about the relationship between alternative employment arrangements and the well-being of workers can be enhanced when the combined effects of employment contract and job conditions are studied.     

Further theoretical results and a comparison between two methods for approximating eigenvalues of perturbed covariance matrices

Covariance matrices, or in general matrices of sums of squares and cross-products, are used as input in many multivariate analyses techniques. The eigenvalues of these matrices play an important role in the statistical analysis of data including estimation and hypotheses testing. It has been recognized that one or few observations can exert an undue influence on the eigenvalues of a covariance matrix. The relationship between the eigenvalues of the covariance matrix computed from all data and the eigenvalues of the perturbed covariance matrix (a covariance matrix computed after a small subset of the observations has been deleted) cannot in general be written in closed-form. Two methods for approximating the eigenvalues of a perturbed covariance matrix have been suggested by Hadi (1988) and Wang and Nyquist (1991) for the case of a perturbation by a single observation. In this paper we improve on these two methods and give some additional theoretical results that may give further insight into the problem. We also compare the two improved approximations in terms of their accuracies.
