钢结构课程教学改革探讨

随着我国钢产量的持续增长,钢结构的应用日趋广泛,钢结构课程在土木工程专业的重要性不断增强。进行钢结构课程的教学改革,培养满足社会需求的钢结构人才是高校教师的责任。围绕钢结构课程的特点,针对多媒体教学、课堂教学内容、实践环节、工程教育几方面,结合本人教学实践经验,提出一些改革措施,与大家商榷。     

A qualitative study on participants’ perceptions of child development accounts in Korea

ABSTRACT

In 2007, Korea implemented Child Development Accounts (CDAs) for institutionalised children in child welfare systems. Since then, the target group and a matching cap of CDAs in Korea have evolved. The target group expanded to include poor children receiving welfare, whereas the matching cap increased from KRW 30,000 (US$26.53) to KRW 40,000 (US$35.38), which is matched at a 1:1 rate. Despite the expansion, there is little empirical evidence examining the extent to which CDAs have influenced the life of participants. Using a content analysis method with a sample (N = 22), this study examines how CDAs have changed children’s mindsets, saving habits, education, future planning and sponsorship. The findings suggest that CDAs have multiple positive influences on children. This study concludes with policy implications for the inclusive and progressive development of CDAs in Korea.     

从列宁、葛兰西到拉克劳、墨菲——论领导权理论的阐释场域

任何理论作为一种由概念构成的阐释体系,它的理论功能的获得都离不开将某些普通的词语专门化、术语化的过程。通过这些被赋予特定涵义的术语的运用,理论展示出它独有的风格和力量。＂阐释场域＂是一个概念坐落于其中而比概念更大的空间或场域。从列宁的政治领导权到葛兰西的文化领导权再到拉克劳、墨菲的话语领导权,阐释场域的变迁展示了领导权理论自身发展变化的轨迹,也给社会实践带来了诸多的不确定性。因此,我们有必要对领导权在各种复杂场域的不同阐释做一个界定。     

兰州市扶贫开发绩效评价及其启示

根据系统工程的理论,在对农村扶贫系统分析的基础上,从政策相关性、扶贫效率、扶贫效果租可持续发展能力四个方面人手,共设置4个准则层、11个关键问题层和35项具体指标,建立了针对贫困地区的综合性扶贫绩效评价指标体系,并以兰州市“三县一区”为研究样本进行总体评价与动态评价。研究结论显示：贫困人口的受益程度与该组织对扶贫项目投入之间呈指数关系;政策相关性是决定扶贫绩效的重要因素之一,生存相关类项目扶贫绩效较高,但可持续发展能力不足。     

我国民营企业诚信文化建设研究

由于民营企业发展历史比较短,市场交往、文化积淀、商业交易还处于发展过程中,普遍存在诚信不足的问题,且相当严重。本文正是在这一视角下对中国民营企业诚信缺失的现状及原因进行了分析,提出了民营企业诚信文化建设的对策和措施。从整体上提高民营企业的诚信水平、促进其健康发展具有重要的现实意义。

BRINGING PERSONALIZED TIES BACK IN: Their Added Value for Biotech Entrepreneurs and Venture Capitalists Interorganizational Networks

Using a unique data set collected in France among biotech entrepreneurs and their venture capital investors (VCs), we measure the added value of personal relationships at the interorganizational level. Our analyses show that when two entrepreneurs share a personal collaboration tie or a personal friendship tie with a VC investor, the probability of having an advice tie and thus exchange tacit knowledge increases significantly. We confirm the importance of this kind of social embeddedness in the biotech industry where personalized ties––as opposed to institutional and contractual relationships––at the interorganizational level had not yet been examined systematically. Our results suggest that strategies of personalization of exchanges are vital for interorganizational learning. These strategies help entrepreneurs to access resources, participate in knowledge building, and co‐orientate activities in this sector.     

Can the American Dream Survive the New Multiethnic America? Evidence from Los Angeles1

Drawing from a survey conducted in Los Angeles, we examine perceptions of achievement and optimism about reaching the American dream among racial, ethnic, and nativity groups. We find blacks and Asian Americans less likely than whites to believe they have reached the American dream. Latinos stand out for their upbeat assessments, with naturalized citizens possessing a stronger sense of achievement and noncitizens generally optimistic that they will eventually fulfill the American dream. We discuss patterns of variation between the racial and ethnic groups as well as variation within each group. Notwithstanding interesting differences along lines of race, ethnicity, and nativity, we find no evidence that the nation’s changing ethnic stew has diluted faith in the American dream.
