食品安全问题的比较分析——基于制度、道德、农村基础比较上的讨论

食品安全问题引发了人们各种各样的思考,有的认为是监管制度不健全,有的认为是道德的沦丧,也有的认为是农村的破败,文章对各种观点在中西比较的基础上进行分析,探究食品安全问题频发的根源。     

湖南食品产业发展及政策扶持研究

从湖南食品产业发展的现状来看,湖南食品产业虽然呈现出持续快速增长态势,产业集聚度逐步提高,研发平台体系得到初步建立,但＂短板＂仍然不少,与农业发达省份比,差距十分明显。为加快发展湖南食品产业,尽快跻身全国十强,湖南省委省政府对食品产业发展高度重视,把食品产业作为推进新型工业化发展的重点产业来抓,对食品产业发展给予多方面的政策扶持。     

日本生协的现状、特点以及对我国消费合作事业的启示

日本生协（日本生活协同组合的简称）是以家庭妇女为主体的消费者自治组织。民主管理和组合员的积极参与提高了成员的凝聚力,并发展了以班组织为中心的共同购买和个人配送等业务。生协的优质服务得到了众多消费者的支持,其组合员人数和户加入率在持续增长,适应消费者生活方式变化的无店铺事业也取得了巨大的成功。借鉴日本生协的发展经验,我国应积极引导居民成立消费合作社,开展社区内的团购业务和家庭配送业务,以解决日益严重的食品安全问题。

Designing optimal food safety monitoring schemes using Bayesian network and integer programming: The case of monitoring dioxins and DL-PCBs

Efficient food safety monitoring should achieve optimal resource allocation. In this article, a methodology is presented to optimize the use of resources for food safety monitoring aimed at identifying noncompliant samples and estimating background level of hazards in food products. A Bayesian network (BN) model and an optimization model were combined in a single framework. The framework was applied to monitoring dioxins and dioxin-like polychlorinated biphenyls (DL-PCBs) in primary animal-derived food products in the Netherlands. The BN model was built using a national dataset with monitoring results of dioxins and DL-PCBs in animal-derived food products over a 10-year period (2008–2017). These data were used to estimate the probability of detecting suspect samples with dioxins and DL-PCBs levels above preset thresholds, given certain sample conditions. The results of the BN model were then inserted into the optimization model to compute an optimal monitoring scheme. Model estimates showed that the probability of dioxins and DL-PCBs exceeding threshold limits was higher in laying hen eggs and sheep meat than in other animal-derived food (except deer meat). Compared with the monitoring scheme used in the Netherlands in 2018, the optimal monitoring scheme would save around 10,000 EUR per year. This could be obtained by reallocating monitoring resources from products with lower probability of dioxin and DL-PCBs exceeding threshold limits (e.g., pig meat) to products with higher probability (e.g., bovine animal meat), and by shifting sample collection from the last quarter of the year toward the first three quarters of the year.     

基于制造商O2O模式选择的O2O供应链定价与网上交货期决策

以制造商主导的O2O供应链为背景,考虑市场需求受价格和网上交货期的影响,针对网上直销和网上代销两种O2O模式分别构建O2O供应链定价与网上交货期决策模型,研究渠道成员的最优策略并分析其性质。再通过数值算例分析了价格敏感型消费者情境和网上交货期敏感型消费者情境下消费者网上销售渠道偏好程度和佣金率对O2O供应链最优策略和利润的影响,并探讨了制造商O2O模式的选择问题。发现：消费者网上销售渠道偏好程度越高,越有利于制造商和O2O平台,但不利于线下门店;佣金率越高,越有利于线下门店和O2O平台,却不利于制造商。当消费者更关注网上交货期时,缩短网上交货期并不利于制造商;而当消费者更关注价格时,延长网上交货期是有利的。制造商的O2O模式选择主要受佣金率的影响,只有当佣金率处于较低范围时网上代销O2O模式是制造商的较优选择。     

Foodwork as re-articulation of women's in/visible work: A study of food allergy blogs

This paper advances our understanding of foodwork as the organization of women's work and racialized, gendered, and classed inequalities in the provisioning, preparation, and consumption of food. Drawing on notions of the in/visibility of women's work, I conceptualize foodwork as the articulation of visible and invisible women's work in the social organization of everyday food practices. The analysis of three blogs, written by women with, or mothers of children with, food allergies, provides a glimpse into the everyday living with food allergy. The investigation of the actual practices of allergy foodwork shows that they are interactive and intersectional patterns of work and make everyday life possible. The paper maps directions for research to explore how foodwork could be organized differently starting from the transformative potential of everyday food practices, blogs, and food allergy.     

Putting place on the menu: The negotiation of locality in UK food tourism,from production to consumption

This paper uses a case study of tourism in the Lake District and Exmoor to explore the relationship between ‘local food’ and sustainable rural tourism in the UK. Drawing on qualitative interviews with tourists, food producers and café, pub and restaurant owners, I use an approach based upon the commodity chain to trace the shifts in the discursive and material understandings of the ‘local’ that take place throughout the tourist food chain. These shifts are shown to occur in response to the need to negotiate the tensions between the ideals and the practicalities of food production and consumption which occur as a result of the relationships that exist throughout the food chain. Such conclusions are shown to be important for our understanding of the links between ‘local food’ and sustainable rural tourism because they indicate that we must attend to the values, as well as the practicalities, that drive the contemporary food sector at all stages of the food chain, from production to consumption.     

Pool‐Point Distribution of Zero‐Inventory Products

We study zero‐inventory production‐distribution systems under pool‐point delivery. The zero‐inventory production and distribution paradigm is supported in a variety of industries in which a product cannot be inventoried because of its short shelf life. The advantages of pool‐point (or hub‐and‐spoke) distribution, explored extensively in the literature, include the efficient use of transportation resources and effective day‐to‐day management of operations. The setting of our analysis is as follows: A production facility (plant) with a finite production rate distributes its single product, which cannot be inventoried, to several pool points. Each pool point may require multiple truckloads to satisfy its customers' demand. A third‐party logistics provider then transports the product to individual customers surrounding each pool point. The production rate can be increased up to a certain limit by incurring additional cost. The delivery of the product is done by identical trucks, each having limited capacity and non‐negligible traveling time between the plant and the pool points. Our objective is to coordinate the production and transportation operations so that the total cost of production and distribution is minimized, while respecting the product lifetime and the delivery capacity constraints. This study attempts to develop intuition into zero‐inventory production‐distribution systems under pool‐point delivery by considering several variants of the above setting. These include multiple trucks, a modifiable production rate, and alternative objectives. Using a combination of theoretical analysis and computational experiments, we gain insights into optimizing the total cost of a production‐delivery plan by understanding the trade‐off between production and transportation.     

辽宋西夏金时期族际饮食文化交流略论

辽宋西夏金时期,中国境内不同经济形态的各民族,在饮食文化相互交流的过程中,明显表现出农耕民族饮食与游牧民族饮食的交融。一方面,农耕民族以谷物食品为主的主食不但在游牧民族的日常生活中占据越来越重要的地位,而且副食、果品、饮品等对游牧民族也产生了广泛的影响。另一方面,作为游牧民族主食的乳肉制品,逐渐成为农耕民族的副食品种,游牧民族副食蔬果类的某些品种、饮食器具,尤其是合餐制的饮食方式对农耕民族也产生了不同程度的影响。同时,相同经济形态的民族,其饮食文化也往往各具特色,并在民族和地区间相互交流。饮食文化在日常生活中的族际交流,不但推动了各民族生活方式的发展和社会经济的进步,而且有力地促进了各民族相互认同意识的发展。
