马克思主义就业理论在我国的应用与发展

马克思主义就业理论在我国的应用发展是中国共产党三代中央领导集体和以胡锦涛为总书记的新一届党中央在马克思主义就业思想指导下,牢固立足于马克思主义就业思想的理论立场,植根于马克思主义世界观,将马克思主义就业思想的基本原理与我国实际相结合的过程,是对我国就业问题的系统反映和总结。毛泽东、邓小平、江泽民、胡锦涛对就业问题的论述,继承和发展了马克思主义就业思想,开辟了马克思主义就业思想的新境界,概括和提升了我国建设、改革的具体实践经验,并自觉地不断地推动着马克思主义就业思想在我国不断发展。     

When work keeps us apart: a thematic analysis of the experience of business travellers

Whilst business travel is deemed important for organisational success and economic outcomes, little is known about the actual process of business travelling from the perspective of individuals who undertake such travel on a regular basis. Thus the current qualitative study examined how business travellers (three women and eight men) attempt to find a balance between work and family, by focusing on how time together and time apart are experienced. The results can be interpreted and framed within work/family border theory in that business travellers' borders are less defined and less permeable, thus requiring them to border-cross more frequently. This necessitates a process of negotiation with key border-keepers (their spouse/partner). Business travellers also undertake compensatory behaviours to make up their time away from family. In order to find a work/family balance, they go through a process of adapting, negotiating and tailoring their lives around their work commitments to alleviate work–life conflict.     

投资组合动态VaR预测模型和预测精度评价

采用4种Backtesting检验方法,检验22个常态和时变投资组合动态VaR预测模型的风险预测精度,发现GJR_GPD_TV_Copula具有最高的投资组合风险预测精度,GJR_GPD_Copula的拟合、密度预测和组合风险预测精度都要高于GJR_SKST_Copula,且Copula模型的组合风险预测精度分别与拟合精度和密度预测精度存在较弱的正相关关系.     

Inclusion of persons with disabilities in mainstream employment: is it really all about the money? A case study of four large companies in Norway and Sweden

This study investigates how large companies respond to public policy measures to ensure the inclusion of persons with disabilities in mainstream employment based on a case study of four companies in Norway and Sweden. The qualitative interviews, which were conducted with company managers, government representatives in Norway, and non-governmental organisations in Sweden, revealed three overarching themes: (1) ‘legitimacy’, (2) ‘financial interests’ and (3) ‘non-financial support’. The results indicate a more proactive response from the Swedish companies, especially regarding persons with intellectual and learning difficulties. The Norwegian companies reveal a high commitment to their own employees. These findings cannot be explained solely using neo-institutional theory, which holds that organisations demonstrate ‘conformity with powerful institutional myths to strengthen support and secure survival'. The results indicate that inclusive targeted corporate policies and programmes, advisory support, and the agency and value choices of the management might matter more.     

Crossing borders with social media: Online social networks and FDI

Social media is embedded in today's internationalization strategy. Companies extend their reach into foreign countries by posting and tweeting. Firms also enhance their mobile capabilities in foreign markets (e.g., knowledge and reputation) through user-generated content in online social networks. Levering on the capabilities-based theory of the multinational enterprise, this paper builds upon a resource-based, industry/network-based, and institution-based view framework. The study provides a comprehensive conceptual and empirical model to explain the effect of social networks on foreign direct investment. Empirical analysis in a global panel dataset of >4500 multinational enterprises suggests that online social networks' activity stimulates foreign capital expenditure and new affiliates. In addition, the article explores the relevance of customer capabilities along with sectoral and institutional moderating effects.     

论伊德的科学价值观

伊德"非中性"的科学价值观揭示的是科学的本体论意义上的价值维度,而传统的科学价值观是事实与价值分离的"中性论"的价值观。伊德认为,传统的科学的价值观没有深入到本体论、生成论意义层次,是缺乏深度的知识论意义上的价值观。停留于此基础上的价值观,难免导致科学的"乌托邦"或"敌托邦"。     

Social Cognitive Factors,Support, and Engagement: Early Adolescents’ Math Interests as Precursors to Choice of Career

The authors examined the central hypothesis that students’ early perceptions of support and sense of engagement in math classes and math activities strongly influence the broadening or narrowing of their math interest. The focus was on the first wave of qualitative data collected from 5th‐, 7th‐, and 9th‐grade students during the 2007–2008 academic year as part of a longitudinal study. Findings indicate the importance of using group work and extrinsic motivation in middle school math classes to broaden interest; peer classroom behavior was often a detractor of math interest.

This essay responds to Lamont’s (2011) article “How Has Bourdieu Been Good to Think With? The Case of the United States,” which appears in this issue.     

Smooth tail-index estimation

The two parametric distribution functions appearing in the extreme-value theory – the generalized extreme-value distribution and the generalized Pareto distribution – have log-concave densities if the extreme-value index γ∈[?1, 0]. Replacing the order statistics in tail-index estimators by their corresponding quantiles from the distribution function that is based on the estimated log-concave density ? f _n leads to novel smooth quantile and tail-index estimators. These new estimators aim at estimating the tail index especially in small samples. Acting as a smoother of the empirical distribution function, the log-concave distribution function estimator reduces estimation variability to a much greater extent than it introduces bias. As a consequence, Monte Carlo simulations demonstrate that the smoothed version of the estimators are well superior to their non-smoothed counterparts, in terms of mean-squared error.     

夏敬观词学贡献论略

夏敬观是晚近词坛著名的词学活动家，其词学活动及词学著述对晚近词坛影响甚大。夏氏词学理论及时总结了他和当时同仁词创作的经验，又是晚近词坛继承王鹏运、朱祖谋等人应用小学方法研究词学整理词籍开创词学研究新格局的重要创获。夏氏词论不仅深化了清代以来对词格律韵调的研究，而且深化了对唐五代北宋词的研究，还总结和深化了历代关于“词”“学”关系命题的思考和探讨，在词学史上具有重要的意义。
