新形势下 FDI 对我国产业结构调整的影响

金融危机之后,利用外资的环境发生了巨大的变化。当前,我国利用外商直接投资面临着新形势,并对产业结构调整的机制产生了影响,除传统的资本、技术、入力途径外,还借助比较优势的变化和国际产业转移等路径来促进产业结构的合理化和高级化,为进一步利用外资促进我国产业结构的优化提出了对策建议。

武术运动员赛前焦虑及心理调控方法探析

采用文献资料法、访谈法、心理测量法、数理统计法等研究方法对武术运动员心理焦虑情况进行调查分析,筛选出5名过度焦虑的运动员进行调控.研究结果表明:女运动员的焦虑数值高于常模(P＞0.05);男运动员的焦虑数值低于常模(P＞0.05).单人项目运动员的焦虑数值高于集体项目运动员(P＞0.05).经采用模拟训练法等心理训练方法进行心理调控之后对这5名运动员进行再测,发现接受心理调控之后的运动员在赛前的焦虑状态得到了明显的改善.

Ranking themes on co-word networks: Exploring the relationships among different metrics

As network analysis methods prevail, more metrics are applied to co-word networks to reveal hot topics in a field. However, few studies have examined the relationships among these metrics. To bridge this gap, this study explores the relationships among different ranking metrics, including one frequency-based and six network-based metrics, in order to understand the impact of network structural features on ranking themes on co-word networks. We collected bibliographic data from three disciplines from Web of Science (WoS), and generated 40 simulation networks following the preferential attachment assumption. Correlation analysis on the empirical and simulated networks shows strong relationships among the metrics. Their relationships are consistent across disciplines. The metrics can be categorized into three groups according to the strength of their correlations, where Degree Centrality, H-index, and Coreness are in one group, Betweenness Centrality, Clustering Coefficient, and frequency in another, and Weighted PageRank by itself. Regression analysis on the simulation networks reveals that network topology properties, such as connectivity, sparsity, and aggregation, influence the relationships among selected metrics. In addition, when comparing the top keywords ranked by the metrics in the three disciplines, we found the metrics exhibit different discriminative capacity. Coreness and H-index may be better suited for categorizing keywords rather than ranking keywords. Findings from this study contribute to a better understanding of the relationships among different metrics and provide guidance for using them effectively in different contexts.
