Progress hindered: the retention and advancement of women in science,engineering and technology careers

Over the last two decades rates of women's participation in science, engineering, and technology careers has greatly increased. However, to date little research exists on how women, especially those in management positions, are performing within these fields. Using data obtained from over 2,493 survey respondents and 28 focus groups, we seek to understand the barriers that hinder the retention and advancement of women in managerial positions in these career fields. Paying particular attention to for‐profit science, engineering and technology firms, we argue that there are significant barriers to female retention and advancement within these fields related to the norms of professionalisation, and that from a human resources perspective firms could do a much better job of leveraging the existing female talent pipeline in these occupations. In addition, we highlight the implications of our findings and provide our policy recommendations to address them.     

河北省城镇居民消费结构变动分析

随着经济的不断发展,居民的消费结构也相应的发生了一些变动。本文采用1997年——2002年河北省城镇居民消费结构的数据,使用因子分析的方法,对消费结构的变动情况进行分析。利用因子得分的结果对原始信息作出解释,并根据河北省城镇居民消费结构的变动情况,结合现实经济发展提出了一些建议。     

中小企业融资中的信贷配给分析

中国中小企业在国民经济中占据了半壁江山,对中国的国民经济和社会发展起到了举足轻重的作用,然而目前中小企业中的融资问题已成为阻碍中小企业发展的主要因素。银行是中小企业间接融资最愿意采取的融资渠道,但是大量中小企业的信贷需求却只有少数部分可以得到满足,即中小企业成为银行“信贷配给”的主要牺牲品。本文试图通过信息不对称理论,利用Stiglitz和Weiss的“信贷配给模型”框架来分析银行对中小企业惜贷的内在原因,并提出了相关的政策建议。     

明星发明人识别与角色分析:来自机器学习领域的实证

明星发明人有助于提高企业研发创新绩效。目前对明星发明人的地位与功能探讨不足,导致企业无法全面掌握发明人信息,难以为研发活动招聘合适的人才。鉴于此,对机器学习领域明星发明人的领导、传播、知识或任务排他等功能和地位进行识别,采用动态网络分析方法确立六类明星发明人,即焦点型发明人、领导型发明人、潜在跨界型发明人、传播型发明人、任务排他型发明人和知识排他型发明人,分析其角色功能。结果表明：部分发明人同时拥有多种地位;领导型、焦点型和知识排他型明星发明人影响范围更广、职业流动性更强,与其他发明人的交互时间更长;隔离同时具有3种地位的明星发明人对焦点型发明人影响显著。     

面向知识产品的生产管理系统框架

知识产品(KP)的生产是当今社会最重要的生产任务之一。知识产品的生产与物质生产一样也有生产效率问题,为提高KP的生产效率,就必须很好地实施KP的生产管理。为此,提出了面向知识产品的生产管理系统(PMSKP)的系统框架。首先给出了PMSKP的概念模型,指出PMSKP主要包括4部分:原创性KP生产管理、复制性KP生产管理、定制性KP生产管理及知识库管理;其次,将PMSKP与传统制造业的生产管理系统(PMS)的特点作了对比分析;再则,进一步研究分析了PMSKP的运作流程;最后介绍了PMSKP的功能结构,为今后进行深入研究打下了基础。     

Aid, Volatility, and Growth Again: When Aid Volatility Matters and When it Does Not

In previous papers the authors have argued that aid is likely to mitigate the negative effects of external shocks on economic growth (i.e. that aid is more effective in countries which are more vulnerable to external shocks). Recently an important debate has emerged about the possible negative effects of aid volatility itself. However, the cushioning effect of aid may involve some volatility in aid flows, which then is not necessarily negative for growth. In this paper the authors examine to what extent the time profile of aid disbursements may contribute to an increase or a decrease of aid effectiveness. They first show that aid, even if volatile, is not clearly as pro-cyclical as is often argued, and, even if pro-cyclical, is not necessarily destabilizing. They measure aid volatility by several methods and assess pro-cyclicality of aid with respect to exports, thus departing from previous literature, which usually assess pro-cyclicality of aid with respect to national income or fiscal receipts. The stabilizing/destabilizing nature of aid is measured by the difference in the volatility of exports and the volatility of the aid plus export flows. Then, in order to take into account the diversity of shocks to which aid can respond, they consider the effect of aid on income volatility and again find that aid is making growth more stable, while its volatility reduces this effect. They finally show through growth regressions that the higher effectiveness of aid in vulnerable countries is to a large extent due to its stabilizing effect.     

外置式电子调速器在进口道依茨柴油机上的应用

一、引言某船用辅机采用了进口道依茨（德国）BF6L913C风冷柴油机作为船用发电机组的原动机。规范（技术规格书）要求，稳态调速率和转速波动率的指标为：稳态调速率≤5％．转速波动率±0．5％。经反复调试和测试。在50％、75％负载时，如稳态调速率达到5％，则转速波动率最高达士0．92％：若要将转速波动率≤±O．5％，则稳态调速率达7-8％。
