谈我国体育体系的根本性大变革

党的十六届三中全会的“决定”中提出，我国体育要脱开同卫生事业的历史性联合，转入文化范畴，这就表明体育的本质功能和根本任务的根本变化，也标志着体育体系的大革变，有其重要意义，其间当然存在许多理论和实践问题，需要我们认真探讨。

对2003年中国成年女足春训状况的调查

通过对2003赛季我国成年女子足球队12支球队的春训实地调查,分析我国女足队伍的现状,并探讨我国女足春训阶段的特点及存在的问题.通过调查发现:1)2003年我国春训成年女足教练员经配置调整后,年轻教练员的比例增多,执教女足年限少;运动员年龄结构不均衡,体重比往年有所下降;2)某些队春训计划内容安排不全面;3)春训总负荷变化可分两种类型,负荷高峰在春训的第二三周或第三四周;春训前四周负荷量与强度,一般均是先上训练量再渐上强度,春训后期即赛前一周量与强度呈下降趋势;4)整个春训赛前调控分加量、专项强化、赛前恢复三阶段进行.

The impact of case characteristics on child abuse reporting decisions.

Drawing distinctions on the basis of at least some case characteristics in making reporting decisions makes considerable sense. Using data from a national survey of mandated reporters that included vignettes in which case and personal characteristics were systematically varied, this paper examines the impact of selected characteristics while controlling for others. The data reveal that respondents noticed and responded to case characteristics. Abuse-relevant judgments and reporting intentions varied, often substantially, as a function of case characteristics. Three case characteristics--previous abuse, severity of abuse, and recantation--were powerful predictors of vignette outcomes. A history of previous abuse led to judgments of greater seriousness, a more salutary impact of a report, and greater likelihood of reporting. More severe abuse was more likely to be labelled as abuse, and was more likely to be reported. When the alleged victim retracted her accusation upon questioning by an authority figure, respondents were significantly less likely to intend a report. Child age, perpetrator intent and family socioeconomic status also influenced abuse-relevant judgments and reporting intentions. Respondents were more likely to intend a report when younger children, lazy or angry perpetrators and children from poorer families were portrayed.     

Assessing the Utility of Item Response Models: Computerized Adaptive Testing

How has Item Response Theory helped solve problems in the development and use of computer-adaptive tests? Do we need to balance item content with computer-adaptive tests? Could we use IRT to evaluate unusual responses to computer-delivered tests?
