爆发力训练与有氧耐力评价指标的相关性研究

为研究同时进行爆发力训练与有氧耐力训练所产生的效果,本研究以14名耐力运动员为实验组(E)、14名耐力运动员为控制组(C)进12周的训练,实验组除15%爆发力训练代替传统耐力训练外,其余训练内容相同。结果发现:5 km跑成绩与RE在实验组明显提高(P<0.05),控制组无差异;5 J在实验组有非常显著性提高(P<0.01),控制组下降显著(P<0.05);VO2max在控制组显著性提高(P<0.01),对实验组变化不明显。混合控制组与实验组数据发现:5km跑时间与RE存在中度负相关(r=-0.54)。结论:同时进行爆发力与耐力训练在不改变VO2max的情况下可以提高5 km跑的成绩。     

《中图法》第5版音乐类目 (J6) 刍议

《中图法》第5版音乐类目的修订基于增设类目、修订类名、增补修改注释、删除/停用类目等多个方面,但在音乐理论类目的细化、音乐作品类目内容与形式的统一等颇受音乐专业图书馆关注问题的修订方面,仍然存在不足或缺失.建议修订工作借鉴《中图法》第3版音乐类目表成功修订的经验,使《中图法》音乐类目表真正成为一部能够全面、正确反映音乐艺术科学特点、具有长期稳定性的统一的音乐文献分类标准.     

Are you too young for the Nobel Prize?

Although age is not supposed to be a criterion for the award of the Nobel Prize, it is commonly believed that it does play a role. Indeed, econometric evidence in this paper also suggests such a role. However, the paper finds that, if there is a preference for older Nobel candidates, this is introduced during the nomination process. The paper actually finds that the Nobel Committee does not favor older nominees and that, if anything, it seems to partially offset the age premium introduced by the nominators.     

Conveying quality and value in emerging industries: Star scientists and the role of signals in biotechnology

This paper addresses the role that scientific status plays in initial public offerings of technology focused firms. The paper builds on the literature of the sociology of science as well as the work of Spence (1974) and Podolny (1993) and argues that the presence of a Nobel laureate affiliated with a firm making an IPO provides a signal of firm quality to potential investors. Moreover, and building on the work of Podolny and Scott Morton (1999) and Stuart et al. (1999) we hypothesize that the importance of status diminishes as other measures of firm quality become available. We test our hypothesis for two periods of initial public offerings in biotechnology. We document that there is a clear difference in “maturity” of the firms across the two windows on a number of metrics. Consistent with our hypothesis that Nobel laureates play an important role as a non-financial signal of firm quality, we find that first-window firms with a Nobel laureate affiliate realize greater IPO proceeds in the amount of $24 million. In the second window the amount of money raised is not significantly different between Nobel and non-Nobel firms. This finding is consistent with the signaling literature that argues that the importance of a signal is inversely related to the availability of cogent information on firm quality. Consistent with this view, we also find a change between the two windows in the importance of other non-financial metrics used to convey value. Our research is one of the first to examine the dynamic nature of signals. Because we are unable to distinguish the extent to which the reduction in uncertainty at the firm level is correlated with the reduction of uncertainty at the industry level, the question remains as to the extent to which the diminished importance of signals in our second period is due to a change in market uncertainty versus a change in firm uncertainty.
