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.

对2000年我国国民体质监测结果的反思

2000年国民体质监测结果显示:我国国民40岁后身体机能呈下降趋势,青少年体质有所下降。主要原因是精神压力增加,身体活动时间减少,加上膳食结构不尽合理,休息睡眠不足,青少年学习负担过重等。倡导健康文明的生活方式,增强自我保健意识,重视并切实贯彻落实学校体育教育和健康教育的有关规定,抓好青少年儿童体格、体能、身体素质和心理等各发育敏感期的教育,从而有效增强青少年体质。中年人合理的膳食、适当的运动、戒烟限酒、保持心理平衡是增强体质、增进健康、延长健康寿命的重要保证。
