食品供应链中质量投入的演化博弈分析

针对频频出现的食品安全事件,以及食品供应链质量投入的外部正效应问题,建立了供应商与制造商食品质量投入的演化博弈模型,并进行求解分析。结果表明:食品供应商与制造商的质量投入策略与双方质量投入产出比密切相关,当双方质量投入产出比不断变化时,出现多种演化稳定均衡。如果"搭便车"行为从对方质量投入中获得的收益很大,则供应商或者制造商进行质量投入的积极性会大大降低。政府进行调控,对于"搭便车"行为进行惩罚,迫使供应商或制造商进行质量投入,对于质量投入产出比较小的供应商或制造商给予补贴,激励他们进行质量投入,增大食品的安全性。

The politics and economics of food and famine in Bangladesh in the early 1970s – with special reference to Amartya Sen's interpretation of the 1974 famine

Bangladesh confronted two formidable food crises in 1972 and 1974. While the government succeeded in averting a widely predicted famine in the first case, it failed to prevent an actual famine in the later case when such a cataclysmic disaster was least anticipated. Evidence suggests that the 1974 famine was caused by successive onslaughts of natural disasters such as floods and droughts, and man-made disasters such as the government's inability to import foods, the directing of subsidised food to the politically vocal urban population, an abrupt fall in food aid and political and administrative corruption that encouraged massive hoarding and the smuggling of food grain. This article argues that Noble Laureate economist Amartya Sen's seminal analysis of the 1974 Bangladesh famine on the basis of his 'entitlement approach' fails to capture most of these circumventing factors. The article also argues that by undermining the politico-administrative dynamics of the famine, and by applying his entitlement approach only half-heartedly in examining it, Sen somewhat trivialises the sufferings of a famine-affected population under a corrupt and inefficient political regime.     

Exploring the Structure of Attitudes Toward Genetically Modified Food

Although it is often thought that the British public is opposed to genetically modified (GM) food, recent qualitative work suggests that most people are ambivalent about GM food and crops. In this article we explore the structure of attitudes in order to examine whether attitudinal ambivalence can be captured by more quantitative methods. Based on the finding that the perceived risks and benefits of GM food can be treated as independent dimensions, we propose a four-way typology of attitudes, consisting of a positive, negative, indifferent, and ambivalent group. This study showed that the differences between the four groups could best be described by three main dimensions: (1) a general evaluative dimension, (2) an involvement dimension, and (3) an attitudinal certainty dimension. While these different attitudinal dimensions have generally been studied in isolation, we argue that they should be studied collectively.     

Evaluating high-tech alternatives by using analytic network process with BOCR and multiactors

The main purpose of this study is to solve a real-world, multicriteria, high-tech selection problem by using analytic network process (ANP). The proposed ANP model consists of a control hierarchy, and a network of connections among the clusters of alternatives, actors and criteria. The strategic criteria were included into the model to rate benefits (B), opportunities (O), costs (C), and risks (R). Then, final synthesis of alternatives was obtained by using rated BOCR. Three actor groups at each step of ANP were cooperated to gain their contributions into the decision as well as to promote the implementation. The results and their interpretations are presented. The management has currently implemented the new high-tech transaction processing system proposed by this study as the best alternative.

Quantitative Assessment of Exposure to the Mycotoxin Ochratoxin A in Food

This article presents the methodology and the simulation results concerning the quantitative assessment of exposure to the fungus toxin named Ochratoxin A (OA) in food, in humans in France. We show that is possible to provide reliable calculations of exposure to OA with the conjugate means of a nonparametric-type method of simulation, a parametric-type method of simulation, and the use of bootstrap confidence intervals. In the context of the Monte Carlo simulation, the nonparametric method takes into account the consumptions and the contaminations in the simulations only via the raw data whereas the parametric method depends on the random samplings from distribution functions fitted to consumption and contamination data. Our conclusions are based on eight types of food only. Nevertheless, they are meaningful due to the major importance of these foodstuffs in human nourishment in France. This methodology can be applied whatever the food contaminant (pesticides, other mycotoxins, Cadmium, etc.) when data are available.
