The role of educational quality and quantity in the process of economic development

We develop a theory of human capital investment to study the effects of school quality on student choices of education, and to understand its effect on economic growth. In a dynamic general equilibrium closed economy, primary education is mandatory but there is an opportunity to continue to secondary education and beyond. High-quality education increases the returns to schooling, and hence the incentives to accumulate human capital. This is caused by two different channels: higher quality makes education accessible to more people (extensive margin), and once individuals decide to participate in higher education, higher-quality increases the investment made per individual (intensive margin). Furthermore, educational quality determines human capital composition and growth. Cross-country data evidence shows that the proposed channels are quantitatively important and that the effect of the quality and quantity of education on growth depends on the stage of development.

普通高校师资队伍建设的现状及对策

"十一五"期间,我国普通高校师资队伍呈现稳定、健康发展的态势。师资队伍的学历结构、职称结构、年龄结构、性别结构日趋合理,但也存在高学历、高职称、教学经验丰富、科研能力强的专任教师比重偏低的情况。学校应加大自主培养人才力度,出台留住人才的有效措施,制定引进人才的优惠政策,进一步加强师资队伍建设。     

第11届全运会太极拳比赛成绩统计分析

运用文献资料法、录像观察法和数理统计法对第11届全运会太极拳比赛成绩进行了研究分析。结果显示:我国太极拳高水平运动员男、女平均技术水平接近,男子略优;在男子太极拳比赛中,对名次影响较大的是运动员的演练水平和难度动作得分,尤其难度动作得分;在女子太极拳比赛中,难度动作是共同弱点,对名次影响较大的是动作质量和演练水平得分,尤其是动作质量得分。

Long-Term Sociopolitical Effects of 9/11 Television Viewing,Emotions, and Parental Conversation in U.S. Young Adults Who Were Children in 2001

This research used a survey to examine how 9/11 television viewing, emotions, and parental conversation influenced current sociopolitical attitudes of young adults who were children in 2001. Young adults who watched more television coverage of the 9/11 attacks as children were found to exhibit lower levels of social trust and support for immigration now, whereas young adults who had more frequent conversations about 9/11 with their parents as children were found to have more confidence in U.S. political institutions and to exhibit more support for immigration. These results illustrate that, although the psychological distress from an event like 9/11 may fade for children not directly affected by the event, the influence of that event on how young people think about the world may remain, and that media coverage of and parental conversation about the event play significant roles in influencing these long-term effects.     

Writing culture; inscribing lives: a reflective treatise on the burden of representation in native research

This paper complicates the contested assumptions surrounding native research by exploring the burden of representation placed on native researchers because they are seen as insiders. This particular issue of representation is important for native researchers to consider, especially in instances where the research is on an understudied or politically charged group, because of the ways in which the socio-political climate influences both the telling and the reading of such research. Drawing on the author’s personal struggles as a Pakistani researcher conducting ethnographic research with Pakistani immigrants in the United States in the post-9/11 climate, this paper explores and critiques the role of the native researcher and the issues involved with representing understudied groups. Specifically, the paper focuses on authenticity, positionality, audience, and accountability. Thus, the paper is a call for researchers to be more reflective and to think more deeply about their positionality and its impact on the various constituents as they research and write. To encourage such reflexivity, the article provides a set of questions for researchers to consider at different stages of the research and writing process.     

Is a higher rate of R&D tax credit a panacea for low levels of R&D in disadvantaged regions?

This paper studies the impact of R&D spending on output as well as forecasting the impact of a regionally enhanced R&D tax credit on the ‘user cost’ (or price) of R&D expenditure and subsequently the demand for R&D. The example we use of a ‘disadvantaged’ region is Northern Ireland (partly because it has the lowest levels of R&D spending in the UK, and partly because the necessary data is available for this region). We find that in the long run, R&D spending has a mostly positive impact on output across various manufacturing industries. In addition, plants with a zero R&D stock experience significant one-off negative productivity effects. As to the adjustment of R&D in response to changes in the ‘user cost’, our results suggest a rather slow adjustment over time, and a long-run own-price elasticity of around −1.4 for Northern Ireland. We also find that to have a major impact on R&D spending in the Province, the R&D tax credit would need to be increased substantially; this would be expensive in terms of the net exchequer cost.

Regional knowledge spillovers: Fact or artifact?

The explanation of different levels of innovation and their spatial distribution represents the central focus of the analysis. The empirical literature documents the incidence of spatial autocorrelation in patenting activities and interprets them as evidence for knowledge spillovers. Alternatively, the authors propose the spatial pattern of input variables in innovation processes as driving forces of patenting autocorrelation. They analyze 51 Nuts 1 regions in Europe and find that the high degree of spatial autocorrelation exhibited by patent applications can be explained comprehensively by the spatial location of the input factors in the knowledge production function. These are traditional indicators on R&D investments and human capital from Eurostat and proxy variables on social capital from the European Values Study. This finding has important implications for the scope of an autonomous regional innovation policy.
