Entrepreneurial endeavors: (re)producing neoliberalization through urban agriculture youth programming in Brooklyn,New York

Driven by social and environmental criticism of the neoliberalization of agro-food systems, urban agriculture today enjoys renewed interest throughout the United States as a primary space to engage the politics of food. Using Brooklyn, New York as a case study, I employ mixed qualitative methods to investigate the contradictions that arise in tensions between the goals of urban agriculture and its practice. Education and youth development programming figure prominently in Brooklyn’s urban agriculture movement and provide insights into understanding the neoliberalization of food politics, especially an emphasis on market mechanisms as central to human well-being and the disciplining of youth in the skills and modes of conduct required by the neoliberal economy. Although current trends indicate that urban agriculture youth programming works to (re)produce neoliberalism and undercuts the political efficacy of Brooklyn’s urban agriculture, these projects simultaneously produce openings for building political solidarities.     

中国古代的水煮方便食品:棋子面与挂面

棋子面最早出现于《齐民要术》,是一种状如棋子、蒸熟以备不时水煮食用的方便食品。唐宋元明各代多作为军食,其烹熟方式也衍生出炒、油煎等,后世又作为幼儿方便食品。近代的"棋子面"则多了一种擀切为菱形的面片。"挂面"一词始出《饮膳正要》,但在唐代敦煌文献中即有"须面"称谓,元代文献也称之为"索面"。是一种水煮方便条状粉食。     

质量安全惩罚下生鲜食品零售商最优策略研究

将生鲜食品质量惩罚额及其惩罚概率作为外生变量,并考虑了两种不同惩罚额度的方式,同时引入生鲜食品质量特征函数,建立了零售商不实行促销价格、实行一次性促销价格和多次促销价格三种不同情况下的预期利润优化模型。结果表明生鲜食品的初始质量水平、销售时间的上限、质量衰减速度以及实行促销的时间点对最优价格和利润都有不同的影响效应。提出了零售商适时采取适当促销决策等建议。     

产业组织模式与食品质量安全——基于水产品的多案例解读

以产业组织新视角,基于未经历产业质量安全危机的水产品行业,融合公共经济学和产业经济学理论,解读产业组织模式对水产品质量安全的作用机理与调控层面,采用多案例研究解构质量安全约束条件下成功产业组织模式的依存情境、利益联结机制、激励约束策略、政府定位要素组合,为食品质量安全问题提供新的解决方案。     

基于城镇化视角的省域粮食安全研究——以江苏省为例

以城镇化为视角,探讨了城镇化发展与粮食安全的关系。将城镇化细分为人口、土地、经济和消费四个方面,构建城镇化发展评价指标,采用熵权法与多元回归相结合的方法,对江苏省2001-2012年的数据进行了实证分析,结果表明经济城镇化与人口城镇化对粮食安全具有促进作用,而土地城镇化与消费城镇化对粮食安全具有不同程度的负面作用,特别是土地城镇化负面作用较为明显。因此,对稀缺土地的科学使用显得至关重要。城镇化与粮食安全的分析结果更加表明,合理的制度安排是确保二者协同发展的重要保障。通过偏向农业的制度安排,合理控制土地使用,引导居民消费习惯,促进城镇化平衡发展,就不会出现大的粮食安全隐患。     

Interference of medical contrast media on laboratory testing

The use of contrast media such as organic iodine molecules and gadolinium contrast agents is commonplace in diagnostic imaging. Although there is widespread perception that side effects and drug interactions may be the leading problems caused by these compounds, various degrees of interference with some laboratory tests have been clearly demonstrated. Overall, the described interference for iodinate contrast media include inappropriate gel barrier formation in blood tubes, the appearance of abnormal peaks in capillary zone electrophoresis of serum proteins, and a positive bias in assessment of cardiac troponin I with one immunoassay. The interference for gadolinium contrast agents include negative bias in calcium assessment with ortho-cresolphthalein colorimetric assays and occasional positive bias using some Arsenazo reagents, negative bias in measurement of angiotensin converting enzyme (ACE) and zinc (colorimetric assay), as well as positive bias in creatinine (Jaffe reaction), total iron binding capacity (TIBC, ferrozine method), magnesium (calmagite reagent) and selenium (mass spectrometry) measurement. Interference has also been reported in assessment of serum indices, pulse oximetry and methaemoglobin in samples of patients receiving Patent Blue V. Under several circumstances the interference was absent from manufacturer-supplied information and limited to certain type of reagents and/or analytes, so that local verification may be advisable to establish whether or not the test in use may be biased. Since the elimination half-life of these compounds is typically lower than 2 h, blood collection after this period may be a safer alternative in patients who have received contrast media for diagnostic purposes.     

食品学科研究生培养:多维协同式过程培养,多元一体化毕业考核

经过几十年的探索和发展,食品学科研究生培养积累了经验、取得了成果,但也存在培养过程不严格、考核制度不完善等问题。当前,食品学科应注重科学研究、国际化和师资队伍建设,实施实验记录全监管、鼓励发表科研成果、提高毕业论文要求,从多维协同式培养狠抓学习过程、多元一体化考核提高毕业门槛两大方向,构建食品学科专业人才培养的新模式。     

物联网基础的食品安全数据挖掘支撑平台的设计

物联网基础的食品安全信息网络存在数据量巨大、数据源异构的突出特点.通过建立和运行模拟系统,在数据源的基础上,提出建立具有共享概念统一规范的本体库、结合云计算技术作为数据挖掘的支撑平台,对提高食品信息的数据挖掘效率,解决食品安全信息的泛在查询和在预警、突发事件处理等方面提供决策支持.
