泰乐松注射液的毒理学试验研究

为提供泰乐松注射液的安全性毒理学评价资料,本试验采用改进Karber法测定小鼠LD_(50);以剂量递增法测定小鼠蓄积性和耐受性;分别以剂量340、130、30mg／kg为3个试验组．设阴性和阳性对照组进行小鼠骨髓微核试验;分别以剂量500、250、120mg／kg为3个剂量组．设阴性和阳性对照组进行小鼠精于畸形试验。结果表明：其LD_(50)为669．80mg／kg,蓄积系数大于5．3,无明显蓄积毒性和耐受性（P＞0．05）,小鼠骨髓微核试验和精子畸形试验结果均为阴性。

Analytical network process for software selection in product development: A case study

Application of software for manufacturing processes is one of the resolutions many enterprises have resorted to in the 21st century. This has been a result of increased complexity of products, globalization, rapid changes in technology and so on. The idea was that application of software especially for product development would increase the competitive advantage of industry nevertheless the irony has been that most of the investment in software has not achieved the expected results. We carry out a case study to introduce a methodology, the analytical network process as a multiattribute strategic decision making approach to help in the selection of appropriate software to suit the product development process of a particular product.     

A Conceptual Model for Researching the Creation and Operation of Supply Networks1

This paper presents a conceptual model for the creation and operation of supply networks. Existing conceptual research relating to interorganizational relationships and networks is reviewed in terms of its relevance to understanding supply networks; this research is drawn from the fields of strategic management, channel management, industrial marketing and purchasing, organizational behaviour and supply‐chain management. The different perspectives each field has on networks are highlighted. Contributions made by each in assisting to understand supply networks are discussed and synthesized. Findings from an exploratory survey are used to structure the design of a conceptual model for analysing the processes involved in the creation and operation of supply networks. The authors identify nine different types of networking activities and discuss the nature of these activities in the context of supply. Four different types of contextual factors relating to supply networks are identified. The model is tested in eight in‐depth case studies and a validating survey of 58 focal firm networks. It is concluded that it provides a robust structure that enabled complex, cross‐case analysis of multi‐variable, multi‐disciplinary data from interorganization product/service supply networks, but that further testing by other researchers is required.     

会议外交与中国参与全球卫生治理的思考

在全球卫生领域以大型会议为代表的国际会议外交已成为全球卫生治理的一种重要形式和载体。文章梳理了全球卫生治理中会议外交的两方面体现,一是以国际会议为代表的会议外交与全球卫生治理,二是以国家行为体为代表的会议外交与全球卫生治理,并进一步归纳了会议外交促成的全球卫生治理进程,包括多次会议促成了全球卫生安全的国际规则《国际卫生条例》,以及历经多年会议磋商促成了全球人口覆盖范围广的《烟草控制框架公约》。中共的十九大报告中对外交工作和健康中国战略有了明确表述,由此需要卫生与外交工作者审时度势、认清角色,通过会议外交表明态度,并以全球卫生会议外交为起点,促进国内立法接续。     

铝钢异种金属CMT焊接变形研究

针对目前使用冷金属过度焊（CMT）对铝钢异种金属薄板进行焊接时,存在焊接质量差,焊接热变形及使用性能低等缺点,对薄板件焊接过程采用SYSWELD软件进行模拟。通过不同的试验参数进行组合,得出金属薄板在X,Y以及整体方向上的焊接变形量,分析不同焊接参数对焊接热变形的影响规律。结果表明：在达到焊接要求的前提下,应尽量减少焊接时间和焊接电流;在一定焊接电压范围内,焊接电压越大,相同时间内焊接变形量就越大,Y方向焊接变形值约为X方向的1.5倍;为了避免焊接变形量过大,宜选用相对较大的焊接速度。     

“学习投入”与“学习性投入”的关系辨析

“学习投入”与“学习性投入”均是以学生为主体的研究,由于两者中文相似、英文相同,容易混淆,所以有必要澄清两者间的差异及联系.研究发现两者在研究目的、理论、方法、应用及相关研究方面均有差异,但两者在研究内容、研究方法及理论基础方面又存在一定的继承性.可见,两者既有联系又有区别,学习性投入是对学习投入的发展,且其研究内容包含学习投入.

新贫困视域下乡村转型的困厄与重构路径

中国社会转型的重要背景之一是全球消费社会的到来。 这使得新穷人现象日渐凸显,并成为影响甚至主导整个社会转型的核心线索。 作为新穷人的典型表现,乡村新贫困既包括在城乡二元结构下,村民难以获得以城市生活方式为参照的社会公认生活水准而引发的结构性贫困,也包括由消费欲望激发的社会心理性贫困。 由此,乡村消费转型表现为如下困境:私人消费中,个体消费认同在地和脱嵌的困境以及家庭消费规范物质化和人伦的两难;集体消费中,消费品“上移冶和“下乡冶的悖论。 为应对这些困境,必须从消费角度,破解“新穷困冶的结构性和文化困境,实行新型城镇化和新农村建设并举。
