方士小说向道士小说的嬗变——以古小说中汉武帝形象的演变为例

唐前古小说中,存在着一个以长生求仙为主题的小说系统,构成此系统的小说前后历经方士小说和道士小说两个发展阶段。作为此小说系统中最常见的人物之一,汉武帝的形象在两汉到六朝的小说本文中发生了持续不断的演变。此文学形象的演变既形象诠释了方仙道向神仙道教演进的规律,亦集中反映出方士小说与道士小说之间的嬗递关系。     

Generalized partially linear varying-coefficient models

Generalized varying-coefficient models are useful extensions of generalized linear models. They arise naturally when investigating how regression coefficients change over different groups characterized by certain covariates such as age. In this paper, we extend these models to generalized partially linear varying-coefficient models, in which some coefficients are constants and the others are functions of certain covariates. Procedures for estimating the linear and non-parametric parts are developed and their associated statistical properties are studied. The methods proposed are illustrated using some simulations and real data analysis.     

中东油气与中国石油发展的战略思考

在当前国际环境下,中国的石油安全战略应是开放和外向型的,其核心思想是“保内争外”,即中国政府应进一步加强对中国石油企业参与国际能源合作的宏观指导和支持;中国石油企业应加强国内油气资源的可持续开发和利用,坚持开展国际能源合作,直面国际博弈。中东国家油气资源丰富,且与中国关系友好,应是中国石油企业对外开展能源合作的首选地区。     

老子的独语与对话

老子是先秦重要的思想人物,他表面上用《老子道德》的独语体来表述一位孤独者的心语,但实际上这本书蕴涵着潜在的对话精神。老子的人文智慧主要通过对话的方式来与世界交流,与人民沟通,与孔子的教喻有所不同,分属中国古代思想不同的言说与表述方式,从思想对话的角度去理解老子,是很有意义的。     

阿尔都塞意识形态理论研究述评

阿尔都塞的意识形态理论独树一帜，曾产生过巨大影响。近年来，学术界对其思想的研究日益聚焦在这一方面，并出现一大批理论成果。目前，国内对这一思想的研究主要集中在对其理论渊源、内容、贡献和缺陷的认识等方面。阿尔都塞在诸多方面时马克思主义的意识形态理论都进行了丰富和发展，甚至触及到经济基础和上层建筑相互作用的机制问题，但其捍卫马克思主义的“初衰”并未真正如愿以偿。

Applicability of a Neuroprobabilistic Integral Risk Index for the Environmental Management of Polluted Areas: A Case Study

Recently, we developed a GIS-Integrated Integral Risk Index (IRI) to assess human health risks in areas with presence of environmental pollutants. Contaminants were previously ranked by applying a self-organizing map (SOM) to their characteristics of persistence, bioaccumulation, and toxicity in order to obtain the Hazard Index (HI). In the present study, the original IRI was substantially improved by allowing the entrance of probabilistic data. A neuroprobabilistic HI was developed by combining SOM and Monte Carlo analysis. In general terms, the deterministic and probabilistic HIs followed a similar pattern: polychlorinated biphenyls (PCBs) and light polycyclic aromatic hydrocarbons (PAHs) were the pollutants showing the highest and lowest values of HI, respectively. However, the bioaccumulation value of heavy metals notably increased after considering a probability density function to explain the bioaccumulation factor. To check its applicability, a case study was investigated. The probabilistic integral risk was calculated in the chemical/petrochemical industrial area of Tarragona (Catalonia, Spain), where an environmental program has been carried out since 2002. The risk change between 2002 and 2005 was evaluated on the basis of probabilistic data of the levels of various pollutants in soils. The results indicated that the risk of the chemicals under study did not follow a homogeneous tendency. However, the current levels of pollution do not mean a relevant source of health risks for the local population. Moreover, the neuroprobabilistic HI seems to be an adequate tool to be taken into account in risk assessment processes.

Making ends meet: perceptions of poverty in Sweden

During the era after the Second World War, Sweden has built a welfare system based on labor market participation and income maintenance. Low unemployment and decent wages are supposed to guarantee people a labor market income or income maintenance, which in turn should provide a proper standard for everyone. However, a rapid increase in unemployment and economic problems have made the future of the Swedish welfare state more uncertain than ever. These circumstances have, among other things, led to the suggestion that Sweden should abandon the income maintenance policy and create a social policy system with the more limited ambition of guaranteeing everyone a minimum income. In that case, one central question must be answered: what constitutes a decent minimum income in today's Sweden? Where should we draw the poverty line under which people will not be forced to live? These questions are central in the current debate. The consensual poverty line method is used in this article to derive a poverty line relevant for today's Sweden. The results shows that more than every fifth household has an income below the consensual poverty line. That is, they have an income that most Swedes would argue is too low to make ends meet. The level of the consensual poverty line was compared with the National Board of Health and Welfare's guidelines for social assistance. The consensual poverty line was shown to be more generous to small households and the norm for social assistance was more generous to larger households. Finally, the expenditure for guaranteeing all Swedish household a minimum income equal to the consensual poverty line was estimated: more than SEK 25 billion per year. The results in the article casts serious doubt on the ability of the Swedish welfare state to secure a decent income to all citizens.
