An Exposure Assessment of Methyl Mercury via Fish Consumption for the Japanese Population

The objective of this article was to propose an exposure assessment model to describe the relationship between fish consumption and body methyl mercury (MeHg) levels in the Japanese population. Individual MeHg intake was estimated by the summation of species-specific fish consumption multiplied by species-specific fish MeHg levels. The distribution of fish consumed by individuals and the MeHg level in each fish species were assigned based on published data from Japanese government institutions. The probability of MeHg intake for a population was accomplished through a Monte Carlo simulation by the random sampling of fish consumption and species-specific MeHg levels. Internal body MeHg levels in blood and hair were estimated using a one-compartment model. Overall, the mean value of MeHg intake for the Japanese population was estimated to be 6.76 μg/day or 0.14 μg/kg body weight per day (bw/day), while the mean value for the hair mercury level was 2.02 μg/g. Compared with the survey data that tabulated hair mercury levels in a cross-section of the Japanese population, the simulation results matched the hair mercury survey data very well for women, but somewhat underestimated for men and all of the population. This exposure assessment model is a useful attempt at further risk assessment with respect to a risk-benefit analysis.     

新疆30年财政收支运行的轨迹

改革开放30年来，尤其是实施分税制以来，新疆地方财政收支的缺口越来越大，究其原因，主要是分税制财政体制使新疆上划中央税收加速增长、地方经济结构调整缓慢和资源优势尚未实现转化。因此，在未来财政收支运行中，应充分预计财政体制变革、新农村建设和新型工业化建设的需求，以及各种减收因素对财政收支的影响，促进产业结构调整是地方财政应当考虑的重要问题。     

文学接受与传播中的“《白鹿原》热”探析

《白鹿原》是广受读者和评论家热捧的小说。探讨其背后的深层原因、民族历史与文化的深刻反思是该书的新突破,文学叙事理念的回归使其具有阅读吸引力,中西方文化思潮相交融的背景使其具有较高的艺术品味和审美价值;出版体制的变革、文学消费观念的变化,文学商业化突出,使具有雅俗共赏特点的《白鹿原》获得读者共鸣。茅盾文学奖等奖项的获得、文学评论家的好评、现代传媒的介入也起到了推波助澜的作用,以上综合因素是《白鹿原》20年来经久不衰的重要因素。     

生态消费模式:社会主义生态文明建设的必然选择

当前,伴随着经济的快速发展,我国新富群体中存在着一种"病态式消费"现象,加上西方消费主义影响,引发了诸多的社会问题。实践证明,只有树立正确的消费观念、克制消费欲望、调整消费行为,才能建立生态消费模式,才能符合社会主义生态文明的要求,实现人与自然的协调发展。     

Demand Systems Estimation With Microdata: A Censored Regression Approach

Demand systems estimation increasingly makes use of household-level microdata, mainly to measure the effects of demographic variables. Data based on these household-expenditure surveys present a major estimation problem. For any given household, many of the goods have zero consumption, implying a censored dependent variable. Techniques which do not take this censored dependent variable into account will yield biased results. We utilize a censored regression approach that is computationally simple, consistent, and asymptotically efficient. The results are then presented and compared with those obtained using an uncensored technique.

产品品种繁多类型企业投入产出表的处理思想与方法

对于生产装配性产品的机械企业，由于产品与原材料种类繁多，将造成企业投入产出表的规模庞大，致使投入产出表的编制、计算和使用产生诸多问题，甚至难以实现。为了控制表的规模，常采用将消耗量相近、生产工艺相近的产品合并的做法。但这种做法严重影响了投入产出表的精度和应用效果。因此，本文讨论了更为有效的解决这类问题的思想和方法。     

二元经济结构下的城乡居民收入消费水平的区域差异分析

我国的国民经济结构是一个典型的二元经济结构,东、中、西三大区域城乡差距依此递增,三大地带内部城乡差距呈现明显拉大趋势。这种现状产生的原因是多方面的,但农业和非农业部门劳动生产率水平的巨大差异和国家的农业投资政策是不容忽视的两个因素。推进二元经济结构演化,缩小城乡居民差距必须树立工农城乡协调发展的战略思想,加大对农业的投入,积极推进农村税费改革,加快城镇化步伐,实施农业产业化经营。     

女性主义视野中的"身体写作"

严格意义上的"身体写作"与女性主义理论密切相关;中国当下的"身体写作"误解了西方女性主义理论的精神,与女性主义理论本身一样有着致命的缺陷;"身体写作"附和着消费主义的时代,在文学精神上有待超越和突破.     

Consumption and its discontents: addiction, identity and the problems of freedom

The focus of this paper is on the notion of 'addictive consumption', conceived as a set of discourses that are embedded within wider socio-historical processes of governance and control. It examines the discursive convergences and conflicts between practices of consumption and notions of addiction, which it notes are consistently represented in terms of the oppositional categories of self-control vs. compulsion and freedom vs. determinism. These interrelations are explored with reference to the development of notions of addiction, and their relation to shifting configurations of identity, subjectivity and governance. Finally, it suggests that the notion of 'addiction' has particular valence in advanced liberal societies, where an unprecedented emphasis on the values of freedom, autonomy and choice not only encourage the conditions for its proliferation into ever wider areas of social life, but also reveal deep tensions within the ideology of consumerism itself.
