关键词： 检验检疫标准化工作   企业   运行绩效   模糊综合评判   贡献率  

摘要： 文章根据模糊综合评判原理,建立了检验检疫标准化工作对出口企业运行绩效作用贡献率计算模型。根据计算结果,检验检疫标准化工作对我国整体企业出口增长率作用的贡献率为5.97%,对企业经济效益作用的贡献率为6.40%,对企业核心竞争力作用的贡献率为7.93%;对不同性质企业运行绩效作用贡献率的研究显示,对出口增长率、经济效益和核心竞争力作用贡献率最高的分别是国有企业、外商独资企业和中外合资企业;对不同专业领域企业运行绩效作用贡献率的研究显示,对出口增长率、经济效益和核心竞争力作用贡献率最高的分别是其他类企业(如卫生、化妆品、鉴定、认证认可、管理服务等领域企业)、机电领域企业和化矿金领域企业。

关键词： 水泥净浆流动度   混凝土外加剂   质量检验  

摘要： 通过对水泥净浆流动度影响因素的分析,推荐一种确定水泥净浆流动度配合比的方法,同时对GB 8077—2000《混凝土外加剂匀质性试验方法》的修编提出了作者的看法。根据作者的这一看法,在大连预拌混凝土技术管理规定中确定了外加剂进厂检验的方法。

关键词： 婚姻满意度   社会支持   应对方式   调节作用  

摘要： 目的探讨社会支持能否改变应对方式并调节婚姻满意度,为婚姻咨询行业提供佐证。方法抽取天津市241名已婚人士,男性118人,女性123人。被调查者接受婚姻满意度量表、社会支持评定量表、简易应对方式问卷的测查。使用差异性检验和调节效应检验的统计方法。采用SPSS13.0软件包进行处理,P〈0.05为差异有统计学意义。结果 60岁以上人群的婚姻满意度与20~29岁,30~39岁,40~49岁,50~59岁存在显著的年龄差异（P〈0.05）。社会支持对积极和消极应对方式与婚姻满意度调节作用乘积项的回归系数非常显著,分别是（t=71.86,R2的变化是89.3%）和（t=14.06,R2的变化是40%）。结论婚姻满意度与社会支持呈正相关。社会支持可随年龄的增长而增长,社会支持是应对方式与婚姻满意度的重要调节变量。

关键词： Teacher study groups   Professional development   Critical colleagueship   Middle-grades mathematics  

摘要： This article examines mathematics teacher collegiality by focusing on both the ways in which teachers interacted as critical colleagues in a long-term professional development project and the evolving role of the teacher-educator-researcher as the facilitator of this project. The professional development collaboration comprised two phases: one focused on reading classroom discourse literature and one focused on supporting each other through cycles of action research related to mathematics classroom discourse. Lord's (1994) critical colleagueship framework is used to examine how a study group of middle-grades (ages 11-16) mathematics teacher-researchers took (or did not take) a more critical stance toward their own teaching practice and that of their colleagues. We found that challenging interactions were related to instances in which the teachers interacted as critical colleagues and were marked by particular features including the use of particular words and the use of personal experience as a form of evidence. We present the ways in which we came to understand what it might look like to scrutinize one's practice and findings related to the development of this type of collegiality across the two different phases of this project. We end with a section in which the teacher-educator-researcher who facilitated the professional development project reflects on the ways in which the analysis caused her to reconsider both the nature of argumentation in mathematics study group settings and what implications this has with respect to her own practice as a facilitator.

关键词： Monthly-rent with variable deposit   Leverage effect seeking hypothesis   Deposit to monthly rent conversion rate   Korea   SEOUL  

摘要： In this paper we describe the structure of the monthly-rent-with-variable-deposit (MRVD) contract a distinct type of rental contract in Korea We demonstrate that the Chonsei contract is one variant of the MRVD contract To explain the MRVD contract we propose a leverage-effect seeking hypothesis Based on this hypothesis we are able to elucidate a variety of rental market conditions in Korea Our hypothesis is consistent with the simultaneous existence of several types of rental contracts and various combinations of monthly rent as well as the up-front deposit in the MRVD contracts We also focused on the deposit-to-monthly-rent conversion rate a critical factor in the Korean rental housing market Our hypothesis indicates that conversion rates vary across local markets depending on local market conditions such as the expected house price appreciation rate The results of our data analysis demonstrate that our hypothesis more adequately explains the observed trend in the conversion rate as well as that in the MRVD contracts (C) 2010 Elsevier Inc All rights reserved

关键词： 欧盟理事会   包装法规   标签制度   混合物   分类   物质   指南   规范性文件  

摘要： 联合国于2002年出版了《全球化学品统一分类和标签制度》（GHS），作为指导各国监控化学品危害和保护人类健康与环境的规范性文件。2008年12月16日，欧洲议会和欧盟理事会通过《关于物质和混合物分类、标签和包装的法规》（1272／2008／EC），即CLP法规。欧盟CLP法规是全球第一部基于联合国GHS的法规，

关键词： 股指期货   正反馈交易  

摘要： 普遍存在的正反馈交易行为,加剧股市波动,必须加以有效治理。本文以正反馈模型为基础,对包括新兴市场在内的全球10个代表性指数进行实证检验。结果表明,上市股指期货能够有效抑制股市正反馈交易,这补充和完善了Antoniouetal.(2005)的工作。本文进而分析了股指期货发挥作用的五条渠道,并认为上市股指期货能够进一步完善内在稳定机制。
