民营担保机构健康发展若干问题的探讨

信用担保机构的风险暴露问题是我国目前经济运行中的一个突出矛盾,导致矛盾产生既有市场约束失效的内在因素,也有制度安排不合理的外在因素。因此,我国的担保业要想健康发展,必须健全监管体系,强化行业监督管理,建立合理的银行与担保机构风险分担机制,健全相关配套制度与措施。

大运动量训练时自由式摔跤运动员应激激素变化的探讨

观察了大运动量训练期8名自由式摔跤运动员应激激素、焦虑水平及主观强度感的变化。研究过程中,每周安排11次大运动量训练,共进行2次实验,每次3个取样点(运动前、即刻和次日晨)。结果显示,两次取样时期次日晨ACTH水平较运动后即刻明显降低;C水平在第二次取样运动后即刻水平和次日晨水平明显高于运动前的,并且该时期运动后即刻C水平也明显高于第一次取样时期运动后即刻水平;E水平在第二次取样运动后即刻水平明显高于第一次取样运动后即刻的,且次日晨该激素水平也明显高于第一次取样次日晨的;血浆β-END水平在第二次取样运动后即刻水平明显高于运动前,也高于第一次取样运动后即刻,第二次取样次日晨该激素水平均低于运动前和运动后即刻水平,同时低于第一次取样次日晨的;血清NE水平变化与β-END水平变化类似;而RPE等级和焦虑水平在两次测试中呈现出运动后即刻水平高于运动前和次日晨的趋势,但不明显;RPE等级与诸多应激激素之间存在着弱相关关系。这预示着,在运动员身体机能评定工作中欲采用简单易行的显示身体机能的外部指标来表现不易测到的内部变化还需努力。

Different types of compression clothing do not increase sub-maximal and maximal endurance performance in well-trained athletes

Abstract

Three textiles with increasing compressive surface were compared with non-compressive conventional clothing on physiological and perceptual variables during sub-maximal and maximal running. Fifteen well-trained endurance athletes (mean ± s: age 27.1 ± 4.8 years, [Vdot]O_2max 63.7 ± 4.9 ml · min^?1 · kg^?1) performed four sub-maximal (～70%[Vdot]O_2max) and maximal tests with and without different compression stockings, tights, and whole-body compression suits. Arterial lactate concentration, oxygen saturation and partial pressure, pH, oxygen uptake, and ratings of muscle soreness were recorded before, during, and after all tests. In addition, we assessed time to exhaustion. Sub-maximal (P = 0.22) and maximal oxygen uptake (P = 0.26), arterial lactate concentration (P = 0.16; 0.20), pH (P = 0.23; 0.46), oxygen saturation (P = 0.13; 0.26), and oxygen partial pressure (P = 0.09; 0.20) did not differ between the types of clothing (effect sizes = 0.00–0.45). Ratings of perceived exertion (P = 0.10; 0.15), muscle soreness (P = 0.09; 0.10) and time to exhaustion (P = 0.16) were also unaffected by the different clothing (effect sizes = 0.28–0.85). This was the first study to evaluate the effect on endurance performance of different types of compression clothing with increasing amounts of compressive surface. Overall, there were no performance benefits when using the compression garments.

Ecological Study of Graduation Rates and GPA in a Library Credit Course

The purpose of this ecological study was to examine the impact of a library credit course on graduation rates and GPA using pre-existing records. Over 20?years of aggregate institutional data were analyzed to evaluate the course's impact on first-time-full-time, white, and black students. Results were mixed: students who took the course were less likely to graduate than their peers who did not take the course but enjoyed slightly higher GPAs at graduation. It was discovered that students taking the course are not representative of the overall student body and struggle academically. Implications for revisions to the library credit course are discussed.     

高校图书馆社会化服务中用户信用体系研究

[目的/意义]针对我国高校图书馆向校外用户提供借阅服务时收取押金的现象,寻求可覆盖大部分用户的免押金信用借阅体系。[方法/过程]分析高校图书馆所遇信用问题的产生原因,对比国内外高校图书馆面向校外读者的借阅制度。[结果/结论]在信息化社会中,高校图书馆社会化服务中的用户信用体系由用户信用信息体系、用户信用评价体系、用户失信惩罚制度、用户信用教育体系、信用风险转嫁机制等构成。
