中国男篮与世界强队比赛攻防效果的比较研究

通过对中国男篮与世界强队比赛技术指标统计的比较,中国男篮在防守效果、进攻方法运用、投篮命中率等方面与世界强队存在着差距.中国队应进一步发挥高大内线队员的优势,加大内线配合进攻比率,提高中远距离投篮命中率,增强防守中的身体对抗能力才可能赶超世界强队.     

排球发球攻击性与比赛结果的探讨

每球得分制规则的实施以来,人们对发球越来越重视,因为发球不仅是进攻的开始,也是得分的主要手段之一.运用技术统计法并结合文献资料,对参加2002-2003,2003-2004赛季步步高DVD杯全国女排联赛中前十名的队进行发球攻击性分析,揭示发球攻击性对比赛结果的影响.     

企业视同销售行为税务处理差异分析

对企业发生的视同销售行为,会计上大多不确认销售收入,而税法却规定视同销售实现,要求计算销售(营业)收入并计算应交税金。在不同的税种下,税法对视同销售做出了具体的规定,税务处理比较复杂。通过对增值税、消费税、营业税、企业所得税的视同销售行为税法之规定进行差异分析,以期完善视同销售行为的税务处理。     

区间数据矩阵转换在股票投资中的应用

由于股票过去的交易价格反映了股票本身很多信息,对预测股价未来的走势有很大的帮助,因此本文从股票过去多个交易日的价格入手,通过空间矩形顶点坐标转换,将区间数据矩阵[1]转化成普通矩阵,利用主成分分析法[3]找出适合进行投资的股票.     

个人特征、人事制度、组织氛围与员工离职倾向——基于乌鲁木齐市15家企业121份问卷的调查结果

在121份企业员工调查问卷数据的基础上,运用有序Probit回归分析模型．分析个人特征、公司人事制度和组织氛围对员工离职倾向的影响。研究表明：企业薪酬的公平性和福利的激励性对员工忠诚度起着举足轻重的作用。拥有完善员工职业生涯规划和培训系统的企业,员工容易与其建立长期的雇佣关系。组织氛围对员工离职倾向也有重要的影响。从事繁杂的工作,得不到领导认可和支持的员工会选择逃离企业。员工离职倾向与个人特征也密切相关,企业进行员工离职管理．应充分考虑员工的个人特征。     

企业销售人员心理资本情绪劳动与离职倾向的关系

通过个体心理资本作为离职倾向的抑制因素和情绪劳动的前因变量,来探讨心理资本对情绪劳动和离职倾向的直接效应以及情绪劳动对心理资本与离职倾向关系的中介效应．采用随机抽样方法选取各地企业销售人员作为研究对象,共发放问卷350份,最后筛选出有效问卷共314份,主要研究工具为修订后的心理资本量表、情绪劳动量表以及离职倾向量表．结果表明：心理资本对离职倾向有显著负向影响,心理资本对情绪劳动中的表层扮演有显著的负向影响,对深层扮演和自然表现有显著正向影响,心理资本对离职倾向的直接效应远大于情绪劳动对心理资本与离职倾向间的中介效应．     

Effects of physical activities that induce moderate external loading on bone metabolism in male athletes

Sports characterized by little or moderate weight bearing or impact have a low osteogenic effect. However, the action of such sports on bone turnover remains unclear. The objective of this study was to determine the effect on bone remodelling of physical activities that induce moderate external loading on the skeleton. Thirty-eight male athletes aged 18–39 years (cyclists, n?=?11; swimmers, n?=?13; triathletes, n?=?14) and 10 age-matched sedentary controls aged 22–35 years participated in the study. The study combined measurement of bone mineral density by dual-energy X-ray absorptiometry and bone turnover assessment from specific biochemical markers: serum bone-specific alkaline phosphatase, osteocalcin, urinary type I collagen C-telopeptide and calcium. Compared with the controls and swimmers, adjusted bone mineral density was higher (P?<?0.05) in triathletes at the total proximal femur and lower limbs. No differences in bone mineral density were found between cyclists, swimmers and controls. Compared with controls, osteocalcin was higher (P?<?0.05) in triathletes and swimmers and urinary type I collagen C-telopeptide was higher in swimmers only. Serum bone-specific alkaline phosphatase was lower (P?<?0.05) in cyclists than in all other groups. In conclusion, an osteogenic effect was found only in triathletes, mainly at bone sites under high mechanical stress. Bone turnover differed in athletes compared with controls, suggesting that bone turnover may be sport-practice dependent. Despite some encouraging observations, it was not possible to show that changes in the bone remodelling process were sport-discipline dependent.     

The influences of school climate and teacher compensation on teachers’ turnover intention in China

This study employed survey research to investigate the differential relationships between dimensions of teachers’ job satisfaction (e.g. salary) and their turnover intention, after controlling for demographic variables (e.g. school location). Five hundred and ten teachers from a northeastern city of China participated. The results of the hierarchical multiple regression analyses indicated that (a) teachers were more likely to stay in teaching profession if they worked in urban schools, always wanted to become a teacher or had a realistic view of teaching before they began their career training and (b) a negative relationship existed between teachers’ compensation and their turnover intention. This study offered some implications for Chinese educational policy-makers and practitioners regarding how to remain qualified teachers.     

Young faculty job perceptions in the midst of Chinese higher education reform: the case of Zhejiang University

Chinese higher education is undergoing fundamental changes to meet the demand of producing high quantity and quality college students. These changes have significantly impacted the work lives of Chinese faculty members. This study investigated Chinese young faculty's job perceptions using four variables: intrinsic motivation, job burnout, job satisfaction, and turnover. The findings revealed that surveyed faculties had high intrinsic motivation, relatively high professional efficacy, and low turnover. However, they showed job burnout as indicated by emotional exhaustion and they demonstrated moderate intrinsic satisfaction and low extrinsic satisfaction. The study proposed that a healthy academic environment is needed for sustainable scholarship development.
