Organic food and the plural moralities of food provisioning

The aim of this paper is twofold. The first aim is to unfold the moral complexity of organic food consumption as part of household food provisioning. By acknowledging this complexity, and the difficulty of determining what is ‘good’ and ‘right’ in food provisioning, the idea is to allow for a better understanding of how organic food may, or may not, fit in with the various concerns of food provisioning. The second aim is to analyse how food provisioners handle this complexity so that food provisioning can proceed as an ordinary everyday activity.The paper analyses empirical material from a study of household food provisioning in Denmark. Theoretically, it draws on French pragmatic sociology as represented by the work of Boltanski and Thévenot on moral conventions and regimes of engagement. The analysis illustrates that food provisioning involves several competing sets of moral conventions and that the status of organic food in relation to these is often uncertain and contested. However, it also identifies among provisioners different strategies for handling this moral complexity in ordinary everyday life. The paper calls for some modesty in trying to change consumer behaviour in favour of organic products. Providing consumers with more information about organic food may not make it easier to determine what is ‘good’ and ‘right’ when buying food. It may only add to the complexity of food provisioning and thus to the need for compromise and pragmatism.     

论德莱塞《嘉莉妹妹》中的哲学沉思

德莱塞之重要性在于:他通过对社会犀利的观察、深切的体会,率先在其作品<嘉莉妹妹>中真实记录了时代跳动的脉搏,展示出美国社会转型时期大众社会价值观的分裂性变化.德莱塞的<嘉莉妹妹>不仅是作家对机械论哲学观的演绎与证明,同时也渗透出作家浪漫主义的理想主义者的一面以及他对新兴消费意识形态的矛盾态度,从而构成他复杂的人生哲学与潜在的动态创作观,而这些主要应归因于他对生命意义的深沉的追求与探寻.     

基于服务驱动假说的消费者自提包裹选择意愿研究

基于淘宝网买家样本,分析了上门投递服务缺陷、上门投递感知风险与消费者自提意愿的关系,试图在新的认知环境下重新检验服务驱动假说。研究表明,上门投递服务缺陷一方面对消费者自提意愿产生了直接的促进作用,另一方面也通过上门投递感知风险的中介效应施加了间接作用;自提感知价值既在上门投递服务缺陷与消费者自提意愿间发挥了调节作用,又对上门投递感知风险的中介作用产生了调节。根据研究结论,可推测当前阶段下服务驱动假说具有一定合理性,相关企业应当明确自提点服务定位,并且需要调整营销推广思路。     

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.

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.

征地过程中的退出意愿、受偿诉求与行为策略——基于被征地者视角的本土研究述评

进入经济高速增长期和社会快速转型期的中国，导致了被征地者这一焦点群体的迅速激增。作为征地制度改革和基层社会治理的重要承载体，该群体在征地过程中的退出意愿、受偿诉求与行为策略等问题已得到不少本土情景下的实证研究的重视，形成了一系列有影响的研究成果。围绕“退出意愿”，研究者提出了个体特征论、家庭结构论、空间区位论、发展期望论、身份锚定论、政策认知论六种理论假说。围绕“受偿诉求”，除了通常作为谈判之焦点的补偿数额，学者们也揭示出被征地者对于分配方案、程序正义、生存保障的诉求。围绕“行为策略”，研究者主要通过博弈模型、案例分析两种方法进行研究。尽管部分研究已经呈现了上述三个维度之间交融沟通的趋势，但三者各自为阵的孤立局面依旧存在。如何促成被征地者的类型知识、需求学说和行动理论之间的逻辑联结，揭示其中的内在机制，建立出一套整合性框架，应当成为下一步的精进方向。     

Morality and Nuclear Energy: Perceptions of Risks and Benefits,Personal Norms,and Willingness to Take Action Related to Nuclear Energy

We examined factors underlying people's willingness to take action in favor of or against nuclear energy from a moral perspective. We conducted a questionnaire study among a sample of the Dutch population (N = 123). As expected, perceptions of risks and benefits were related to personal norms (PN), that is, feelings of moral obligation toward taking action in favor of or against nuclear energy. In turn, PN predicted willingness to take action. Furthermore, PN mediated the relationships between perceptions of risk and benefits and willingness to take action. In line with our hypothesis, beliefs about the risks and benefits of nuclear energy were less powerful in explaining PN for supporters compared to PN of opponents. Also, beliefs on risks and benefits and PN explained significantly more variance in willingness to take action of opponents than of supporters. Our results suggest that a moral framework is useful to explain willingness to take action in favor of and against nuclear energy, and that people are more likely to protest in favor of or against nuclear energy when PN are strong.
