食品企业舆情涌现的致错因子体系及作用机理

食品安全关系到公众利益与社会稳定,是国家战略性问题。多发的食品安全事件损害了消费者的身心健康,由其形成的食品安全舆情也损害了企业的品牌形象和声誉。如何正确应对和引导食品安全舆情,对于食品行业和企业以及应急管理研究来说都是一个亟待解决又颇具挑战性的课题。运用系统分析、应急管理与故障树等有关理论和方法,进行食品安全突发事件舆情及其形成和传播机理、食品安全舆情涌现的致错因子体系与作用机理,并以A食品公司为例进行案例分析。     

Food Sovereignty in Everyday Life: Toward a People-centered Approach to Food Systems

Abstract

This paper proposes a theoretical approach that de-centers ‘food’ in food-related research, placing social life as the point of departure for a critical analysis of food systems and the search for alternatives. Using a relational conception of food as a nexus of multiple, intersecting social-historical processes, a ‘people-centered’ approach illuminates the social elements that can inform resonant and locally inflected strategies for food sovereignty, particularly for urban communities in the USA. Building on theoretical concepts of primitive accumulation, articulation, and everyday life, as well as empirical work with the Chicago-based Healthy Food Hub, this paper explores the relationship between everyday food practices and historical processes of proletarianization as they are produced, reproduced, and contested at multiple conjunctures. In these spaces of contestation, the capacity for diverse communities to re-articulate social relations through everyday food practices could provide a potentially powerful pathway not just to food sovereignty, but an alternative to life under capitalism.     

Caste,purity, and female dress in IT India: Embodied norm violation as reflexive ethnographic practice

This article proposes the methodology of embodied norm violation for overcoming the dichotomy between cognitive reflexivity and embodied ethnographic practice. The methodology is derived from the author's own embodied experiences as a female Indo-German ethnographer in the field of IT India. For exemplifying the methodology and its potential, this article focusses on two field-related phenomena, namely adhering to a vegetarian diet and dressing the female body. It uses them to gather insights on embodied purity and caste in IT India and discusses implications with regard to the political body (Foucault), the social body (Bourdieu), and the individual body (Merleau-Ponty). The theoretical contribution lies in suggesting embodied norm violation as a reflexive research methodology which delivers organizational insights beyond text, discourse, and cognition. On the empirical level, embodied norm violation enabled the researcher to uncover the pre-reflexive and gendered dimension of IT India as a neocolonial, modernist, and male project.     

A Recipe for Change: Reclamation of Indigenous Food Sovereignty in O-Pipon-Na-Piwin Cree Nation for Decolonization,Resource Sharing,and Cultural Restoration

Abstract

O-Pipon-Na-Piwin Cree Nation (OPCN), an Indigenous community in northern Manitoba, Canada, was flooded and forced to relocate from ancestral lands to a nearby settlement under such circumstances. Regaining strength from their inherent cultural values grounded in their relationship with the land, OPCN eventually formed a community-based food program called Ithinto Mechisowin (IMP) (‘food from the land’). This article uses OPCN's concept of resource (wechihituwin) and decolonization (pasekonekewin) to present a nuanced understanding of Indigenous food systems in Canada. We argue that the ways in which IMP inspires reconnection with land, thereby improving access to culturally appropriate healthy food, are steps forward in strengthening Indigenous food sovereignty.     

信息处理模型与字词识记

汉字识记是汉语学习的基础,它直接关系到语言能力和交际能力的培养。因此,如何有效地帮助学生识记和掌握汉字是对外汉语教学值得深入研究的问题。笔者以信息处理模型为理论依据,结合教学实践,探讨对外汉语教学的原则与方法。     

我国水产品外贸企业应对国际贸易壁垒的策略研究

近年来,由于某些国家以种种借口滥用反倾销和名目繁多的技术性贸易壁垒等措施来保护本国市场,使得我国水产品外贸企业在进一步开拓国际市场时常常遇到不少障碍。以反倾销和技术性贸易壁垒为主的国际贸易壁垒已经成为制约我国水产品出口的重要因素,因此,如何采取有效措施,积极应对,乃是一项刻不容缓的重要课题。     

基于Rough Sets的传感器异常数据处理

在各种传感器的应用中,经常要对传感器的测量数据进行处理,以保证测量结果的可靠性．为了利用粗糙集理论处理不确定数据的优点,根据粗糙集理论的思想,先由已知测量数据提取出决策表,再进行补全、离散化等预处理,最后进行属性约简并提取出分类规则,对测量数据进行分类,剔除测量数据中的异常数据．实验结果显示该异常数据发现方法比常用的异常数据处理方法更为客观、精确和可靠．     

高职数控技术技能专业紧缺人才的培养

目前我国高职教育在政府的重视下,取得可喜的成果。高职办学正在迅速发展,正在为社会快出人才而奋斗。而当今我国加入WTO后,经济全面与国际接轨,我国正在成为全球制造业的加工中心。外国企业正在国内高起点建厂,各企业为增强竞争能力,已开始广泛使用先进的数控技术。目前数控人才的缺乏已成为中国制造加工业高速发展的瓶颈,三年制培养时间过长,不能适应现在发展的需要,将三年制改为二年制的培养模式势在必行。在最短时间内培养出适合各企业紧缺的数控人才,解决企业招工难的问题。     

食品(药品)安全时代的分子光谱法

本文对分子光谱法中最常用的红外光谱法、近红外光谱法、拉曼光谱法、紫外可见分光光度法、荧光光谱法以及超光谱成像技术等在食品(药品)安全领域的研究、应用、存在问题及发展前景等方面进行了综述。重点阐述了故意掺杂(比如保健品掺杂化学药品等)、无意残留(比如果蔬农药残留等)、其他物种混淆(比如他种药品冒充另一种化学药品等)三种情况下,采用光谱分析的特点和难点,尤其是这些分析对象对信息处理以及硬件设备的要求。在食品(药品)安全时代,需要分子光谱法大有作为,也大有可为。     

我国加工贸易转型升级的理论研究

传统的国际贸易理论不仅表明加工贸易能充分发挥我国的比较优势,并为确定我国在国际分工中的地位提供理论指导;产业内贸易理论指明了我国加工贸易产业结构转型升级的方向;跨国公司理论解释了加工贸易与我国吸引外商直接投资的紧密联系;国家竞争优势理论指出建立国家竞争优势是我国加工贸易可持续发展的动力。深入研究这些理论可以进一步明确如何开展加工贸易,确定中国在国际分工中的地位。
