我国转基因食品安全管理存在的主要问题——由美国转基因产品“黄金大米”引发的思考

由于转基因食品安全性的不确定,整个世界有关转基因食品的安全管理受到全社会的伦理审视和极度重视,各国制定极为严格的监管政策对转基因食品的研发、生产、流通与国际贸易等环节进行规制和管理.通过对国际上和中国对转基因食品安全管理的对比认识,提出转基因食品安全管理的基本思路,有助于国家制定既能保障食品安全,同时又能促进转基因技术创新发展的安全管理制度,为中国转基因技术的突破及转基因产品的商业化提供理论依据.     

顾成、罗汝芳“文”“武”二墓探源

明镇远侯顾成以武官身份镇守贵州而建立功勋,其墓葬后世称“武墓”;罗汝芳是阳明后学的代表性人物,其墓葬后世则称“文墓”。传二墓均立于安顺九溪村河畔。已有研究表明,“武墓”确为顾成长子顾统与其妻俞氏合圹,《顾夫人俞氏圹志》厘清了该墓茔之讹传数百年的谬误;“文墓”虽疑窦重重,为考古研究带来了许多疑云,却增加了对罗汝芳晚年生活际遇、思想由激进转为隐逸突变的深思,且从罗汝芳的“韦氏之识”“伤子之痛”和“隐居之谜”事件分析,其隐逸并葬于安顺九溪之说极为可能。     

追寻解放的革命教育理念与实践：以西北军政大学为中心

西北军政大学作为解放战争时期中国共产党创办的区域性军政大学之一,接续抗日军政大学的革命传统,呼应世界范围内民族解放的时代诉求,开展了基于解放目标的教育动员行动。通过开放的办学方式、灵活的教学内容、明确的革命导向,西北军政大学将思想教育与解放事业相结合,以批判的武器支持武器的批判,适应了中国革命和建设的实际需要,培养了一批革命干部与专业人才,形成了植根中国社会实际和革命斗争需要的特殊高等教育模式,具有特定的时代意义与深远的历史影响。     

模糊评价模型在食品供应链管理风险中的应用

基于食品供应链风险评价指标体系,建立模糊评价模型,并运用该模型对食品供应链风险进行综合评价,实证分析得出:快餐巨无霸麦当劳在供应链管理中的风险较低。     

我国《食品安全法》的审视与完善

两年多来,我国《食品安全法》实施情况如何,值得审视。实践中具有哪些积极意义,还存在哪些问题;通过借鉴发达国家有关食品安全方面的法律制度和成功经验,提出立法完善意见和政策建议。     

哈军工与哈工大之关系及其他(1952-1954)——以哈尔滨军事工程学院档案为主

1952—1954年,苏联援助新中国创办的第一所高等军事技术学府哈尔滨军事工程学院与20世纪20年代以苏联为主创建的哈尔滨工业大学之间,有着许多鲜为人知的关系。哈尔滨军事工程学院在选择校址、学科建设、师资培养以及学员实习等教学环节,大都是在充分考虑哈尔滨工业大学这一因素的前提下确定的、尤其是陈康白担任哈尔滨工业大学校长期间,在自身师资缺乏的情况下,积极支援哈尔滨军事工程学院的教学和师资队伍建设,为国防科技人才的培养做出了积极的贡献。两校之间这种非同寻常的关系,在很大程度上是由于苏联全面介入新中国高等教育,尤其是国防科技工业领域所致,继而对各自产生十分不同的影响,耐人寻味。     

“现代化”之后的东亚农业和农村社会——日本、韩国和台湾地区的案例及其历史意蕴

日本、韩国和台湾地区的农业和农村通常被看作中国大陆农业和农村的样板。但是,以粮食大量依赖进口,农村的空洞化、老龄化和劳动力不足,以及与新娘短缺相伴的外籍新娘的涌入为代表,这三个国家和地区的粮食和人口的再生产都处于难以持续的状态,现代化之后的农业和农村实际上都处于严重的危机之中。这种状况与其具有高度竞争力的工业和拥挤的城市形成鲜明对照,它是东亚模式或东亚资本主义的一种必然结局,也对中国大陆农业和农村的未来演变趋势提出了警示。     

“野食”:饮食安全的红线

这次的新冠肺炎疫情震撼了世界,导致此次疫情的重要病源来自野生动物,而"元凶"似乎是人们的"野食"。野生动物纵有危险之虞,如果人们不捕杀、不食用,危险终究不会发生。因此,"野食"成了关键性的话题,本文从人类学的角度对"野食"进行分析。文中个别观点曾经在拙著《饮食人类学》[1]中有所论及,只是在当下的特定语境重新讨论更不寻常,语义也完全不同。     

A chain game for distributed trading and negotiation

This position paper introduces a simulation gaming environment for enacting a production network. The environment aims to be an integrative laboratory for investigating supply networks, as well as being a versatile training tool. The primary focus is on food production networks. The environment enables a number of teams of participants, each representing one actor in a food chain, to conduct business together. The teams can have the role of auction, co-operation, wholesaler, factory, retail chain, and retail outlet. Producers and consumers are either enacted or simulated. The game leaders freely determine the products and production methods in each run of the game. The gaming environment takes performance, process and institutional aspects of chains into account. It is particularly suited for investigating issues of sustainability and trust. Currently the gaming environment is under development. The paper presents version 1B. This version can be found at http://www.chaingame.org. It runs on the Web, enabling to model distributed chains.     

Estimates of per Capita Fish Consumption in the U.S. Based on the Continuing Survey of Food Intake by Individuals (CSFII)

This paper presents estimates of daily average per capita fish consumption by age and gender for the 48 conterminous states. The estimated consumption rates are reported for three fish habitats: freshwater/estuarine fish, marine fish, and all fish. The estimates were generated from the combined 1989, 1990, and 1991 Continuing Survey of Food Intake by Individuals (CSFII), a national food consumption survey conducted by the United States Department of Agriculture (USDA). Point and interval estimates of per capita fish consumption were generated from the empirical distribution of daily average per capita consumption. The point estimates include the mean, 50th, 75th, 90th, 95th, and 99th percentiles. Ninety percent confidence intervals are provided for the estimated mean and 90% bootstrap intervals are provided for percentile estimates. Information in a recipe file provided by USDA was used to calculate the amount of fish in recipes which contain fish. The estimated consumption rates are based on the weight of fish in its prepared or as consumed condition. The estimated mean consumption rate for all fish for the U.S. population of the 48 conterminous states was 15.65 grams/person/day (C.I.:14.67–16.63) of which 4.71 grams/person/day (C.I.:4.17–5.25) was freshwater/estuarine fish and 10.94 grams/person/day (C.I.: 10.14–11.73) was marine fish.
