新《义务教育法》的突破与创新

有效解决我国义务教育改革发展面临的重大问题是修订1986年《义务教育法》的根本动因。新《义务教育法》在义务教育法的立法目的、义务教育的基本性质、经费投入、政府责任、学校安全、教育公平与均衡发展、教师队伍、法律责任等方面都有一些新的、重大的突破。这部《义务教育法》是我国义务教育立法和义务教育发展进程中的一个新的里程碑。     

实行新规则后排球比赛规律初探

通过对1998～1999年全国排球联赛,1999年亚俱杯男排赛、4国女排邀请赛、世界女排大奖赛总决赛、我国男女排集中秋训、世界杯比赛的调研,探讨了实施新规则对排球技战术发展带来的变化。结呆表明;新规则实施后,一攻作用得到粮本改变,提高防反能力关系到我国排球市场的前途;各项技术得分比例发生变化,二传队员压力增大,发球作用影响深远;自由防守队员接发球和防守效果优于其他队员,但我国与外国队相比还有较大差距;强弱队之间比分差距缩小,胜负偶然性增强;比赛时间相对缩短,比赛强度和难度提高;队员运动寿命延长,使用新人风险加大。我国排球技术战术指导思想的内涵需作适当调整与补充。     

Acute responses of soccer match play on hip strength and flexibility measures: potential measure of injury risk

Abstract

Regular measurements of groin risk factors may offer a preventive measure against injury. Therefore, the aim of this study was to (1) determine minimal detectable change (MDC) and reliability of hip flexibility and strength measures and to (2) identify the effect soccer match play load has on these measures. Reliability was determined for bent knee fall out test, hip abduction and adduction (hand-held dynamometry (HHD)) in 20 trained youth male soccer players. Reliability was evaluated with the intra-class correlation coefficient (ICC_[2,1]), 95% confidence intervals (CI). Hip strength and flexibility measures were taken before and after an international friendly match. Intra-rater reliability ICC ranges were bent knee fall out (0.75–0.90), abduction (0.83–0.90) and adduction (0.72–0.96). Inter-rater ICCs (95% CI) were bent knee fall out test [0.75 (0.39–0.90) right, 0.71 (0.27–0.89) left hip]; abduction [0.80 (0.50–0.92) right, 0.81 (0.53–0.92) left hip] and adduction [0.72 (0.31–0.89) right, 0.70 (0.26–0.88) left hip]. MDCs were as low as 20.7% of the mean for hip flexibility and 12.5% for strength. In conclusion, HHD and the bent knee fall out test are reliable tools to measure changes in hip strength and flexibility. Finally, a threshold may exist in which match play load negatively impacts hip flexibility.     

Using Blackboard in Library Instruction: Addressing the Learning Styles of Generations X and Y

Studies show that recent generations of college students have a learning style with identifiable characteristics. Library instruction efforts must adapt to these learning styles. Course management software (CMS), such as Blackboard, is one resource available to academic librarians to meet the challenges posed by the "Net Generation." At Stetson University, the use of Blackboard courseware in library instruction sessions successfully addressed the unique learning styles of students.     

Increased plasma vaspin concentration in patients with sepsis: an exploratory examination

Introduction

Vaspin (visceral adipose tissue-derived serpin) was first described as an insulin-sensitizing adipose tissue hormone. Recently its anti-inflammatory function has been demonstrated. Since no appropriate data is available yet, we sought to investigate the plasma concentrations of vaspin in sepsis.

Materials and methods

57 patients in intensive care, fulfilling the ACCP/SCCM criteria for sepsis, were prospectively included in our exploratory study. The control group consisted of 48 critically ill patients, receiving intensive care after trauma or major surgery. Patients were matched by age, sex, weight and existence of diabetes before statistical analysis. Blood samples were collected on the day of diagnosis. Vaspin plasma concentrations were measured using a commercially available enzyme-linked immunosorbent assay.

Results

Vaspin concentrations were significantly higher in septic patients compared to the control group (0.3 (0.1-0.4) ng/mL vs. 0.1 (0.0-0.3) ng/mL, respectively; P < 0.001). Vaspin concentration showed weak positive correlation with concentration of C-reactive protein (CRP) (r = 0.31, P = 0.002) as well as with SAPS II (r = 0.34, P = 0.002) and maximum of SOFA (r = 0.39, P < 0.001) scoring systems, as tested for the overall study population.

Conclusion

In the sepsis group, vaspin plasma concentration was about three-fold as high as in the median surgical control group. We demonstrated a weak positive correlation between vaspin and CRP concentration, as well as with two scoring systems commonly used in intensive care settings. Although there seems to be some connection between vaspin and inflammation, its role in human sepsis needs to be evaluated further.Key words: adipocytokine, inflammation, vaspin, CRP, intensive care
