我国《科学学与科学技术管理》和《科学学研究》1999-2003文章内部结构和资助状况浅析

应用统计学软件SPSS,对《科学学与科学技术管理》和《科学学研究》1999—2003年刊发的825篇研究性论文的发表年、文章内部结构及资助者进行文献统计分析,以深入透析我国科技管理研究所处的阶段、研究方向和研究内容,找出其研究的特点与不足。目前科学学研究性论文研究内容有三个倾向即“集中化倾向”、“理论化倾向”和“国家政策倾向”;研究阶段多处于“问题描述阶段”;研究方法以“非经验研究”为主;基金资助比例失调。

我国指数基金运作与绩效研究

一、引言指数基金起源于美国 ,1971年美国威弗银行(ＷｅｌｌｓＦａｒｇｏＢａｎｋ)向机构投资者推出了世界上第一只指数基金。指数基金是投资基金的一种类型 ,它是以证券市场的股票指数为投资对象 ,导入指数投资概念 ,采用指数化投资 (也叫资产等级投资或消极投资 )方法 ,跟踪目标指数 ,使自己本身的投资收益率与市场指数收益率基本一致的一种证券投资基金。我国于 1999年 7月 14日正式推出了两只指数基金———基金兴和和基金普丰 ,在设计时均借鉴了国外的运作经验———投资运作跟踪大盘运行 ,同时又体现了自己的独到之处———不完全是纯…     

Coherent mortality forecasting by the weighted multilevel functional principal component approach

In human mortality modelling, if a population consists of several subpopulations it can be desirable to model their mortality rates simultaneously while taking into account the heterogeneity among them. The mortality forecasting methods tend to result in divergent forecasts for subpopulations when independence is assumed. However, under closely related social, economic and biological backgrounds, mortality patterns of these subpopulations are expected to be non-divergent in the future. In this article, we propose a new method for coherent modelling and forecasting of mortality rates for multiple subpopulations, in the sense of nondivergent life expectancy among subpopulations. The mortality rates of subpopulations are treated as multilevel functional data and a weighted multilevel functional principal component (wMFPCA) approach is proposed to model and forecast them. The proposed model is applied to sex-specific data for nine developed countries, and the results show that, in terms of overall forecasting accuracy, the model outperforms the independent model and the Product-Ratio model as well as the unweighted multilevel functional principal component approach.

风险社会视域下“校园贷”问题的生成及应对

"校园贷"是一个横跨"在场空间"与"缺场空间"的"跨界性"问题,以风险社会理论为视角进行分析,可有效地贯通网上、网下两个空间的情境性区隔,是从整体上对其进行解读的理想选择。它的异变主要涉及社会急剧转型、网络技术发展及大学生群体结构三个风险源:社会转型过程中风险的无序释放是催生"校园贷"问题的现实动因,网络技术的风险特征是催生"校园贷"问题的潜在根源,大学生群体消费欲望强而财商低的结构特点是催生"校园贷"问题的重要因素。防范"校园贷"风险的关键在于建构政府主导、社会参与、个体自省的风险应对共同体,以减少各类风险发生交叠、共振的频率。     

Gambling and Sport: Implicit Association and Explicit Intention Among Underage Youth

This study examined whether an implicit association existed between gambling and sport among underage youth in Australia, and whether this implicit association could shape their explicit intention to gamble. A sample of 14–17 year old Australian participants completed two phases of tasks, including an implicit association test based online experiment, and a post-experiment online survey. The results supported the existence of an implicit association between gambling and sport among the participants. This implicit association became stronger when they saw sport-relevant (vs. sport-irrelevant) gambling logos, or gambling-relevant (vs. gambling-irrelevant) sport names. In addition, this implicit association was positively related to the amount of sport viewing, but only among those participants who had more favorable gambling attitudes. Lastly, gambling attitudes and advertising knowledge, rather than the implicit association, turned out to be significant predictors of the explicit intention to gamble.
