选择广东省游泳队游泳运动员为研究对象,对不同距离自由泳赛后血乳酸水平作了比较,研究了赛后血乳酸与成绩的关系,以及纵向观察伴随成绩提高血乳酸水平的变化。结果表明:自由泳中,100m和200m赛后血乳酸最高,血乳酸水平与成绩不存在显著相关。半年多的纵向观测显示,随运动成绩的提高,乳酸水平显著提高。  相似文献

BL (Boys’ Love) fandom has been regarded as a counterpublic by some academics since 2005. In this article, I investigate the dispute over “real-person” texts (texts based not on fictional characters but on real people, both public and non-public figures) on the BL board of PTT BBS in Taiwan as a case-study. The dispute is significant in the sense that, ostensibly, there were a few young female BL fans who actively defined what the BL scene consists of, as only these young women were involved in the dispute. Nevertheless, a closer look at the dispute reveals that the mainstream values actually played a significant role in framing the fandom in question. I then argue that the objection to the real-person texts should be regarded as a refusal by the BL fandom to be part of a counterpublic. The dispute started with a clarification of the genre, equating real-person with real gay people, BL with fantasy, and gay with reality. It is on this basis that real-person texts were not regarded as part of BL practices. Moral issues, such as respect and politeness, were also raised to question real-person texts. The conflict intensified, leading finally to the total exclusion of real-person texts from the BL board. To sum up, the dispute over real-person texts demonstrates how BL fans actively (re)formed the shape of the BL board; at the same time, it represents a refusal and exclusions, which place this counterpublic into question.  相似文献

This paper investigates the conditions when a research joint venture (RJV) will involve a university as a research partner. We hypothesize that larger RJVs are more likely to invite a university to join the venture as a research partner than smaller RJVs because larger ventures are less likely to expect substantial additional appropriability problems to result because of the addition of a university partner and because the larger ventures have both a lower marginal cost and a higher marginal value from university R&D contributions to the ventures’ innovative output. We test this hypothesis using data from the COoperative REsearch (CORE) database, and those data confirm the hypothesis.  相似文献

While the importance of a supportive context for entrepreneurship is widely acknowledged, its antecedents are rarely investigated. We apply the concept of organizational climate to higher education institutions and examine the drivers of students’ perceptions of the entrepreneurial climate in their university. Combining data from two unique datasets and using multilevel techniques, we analyze the relationship between university characteristics and such climate perceptions of 8009 students at public universities in Germany. We find university entrepreneurship measures to have a positive effect on students’ climate perceptions, which also depend on students’ background and gender. In addition, we find evidence for different peer effects, depending on students’ affinity for entrepreneurship. For the general student population, including entrepreneurship content in their normal studies seems to be required to initiate a social process of sensemaking. However, students’ perception of the entrepreneurial climate only depend to a certain degree on intentional entrepreneurship measures. In our study, general university characteristics have the strongest influence on climate perceptions. Overall, our study adds to our understanding of which parameters are important for establishing a more favorable and inspiring climate for becoming an entrepreneur at higher education institutions.  相似文献
