警察体育基础课教学的改革与创新

针对公安院校新生入学后普遍存在身体素质偏差，加之警察体育基础课课时少，训练内容、方法和手段单一等问题，我院警体部在进行“警察体育基础课”的教学时，首先转变教学理念，对教材体系、考试方式、教学方法等进行了改革与创新，形成了比较系统的警体基础学科理论和教学训练体系，并通过多年教学实践的检验，取得了较显著的效果。     

“幼态持续”及其人文意蕴

幼态持续学说向我们揭示:人是"永恒的儿童";童年是潜在适应的"贮藏室";发育缓慢是人类个体童年的特征;发育缓慢使人类大受其益;等等。幼态持续学说在人文学科上最直接的贡献是它的儿童观意蕴。它也使儿童本位观念和童心主义哲学获得了生物学、进化论等自然科学方面有力的支持支援支撑。幼态持续学说对童年的发现,对于改变以童年为敌的社会现实具有重要意义,对于小觑童年、毁坏童年、急匆匆将儿童赶往成年世界的想法和做法,是一剂解药。     

Risk Factors Associated with the Chronicity of High Potential for Child Abuse and Neglect

The present 4-year follow-up study involves 56 mothers who were evaluated by social agencies as being abusive and neglectful or at high risk for child abuse and neglect. The aim of the study is to analyze the relationship between psychosocial risk factors (relating to the history and current situation of the mothers) that were present at the time the families were initially recruited and the fact that some of the mothers continue to show a high potential for child abuse and neglect (chronic abuse and neglect), whereas others were able to overcome the problem (transitory abuse and neglect). Results indicate that the following variables are particularly associated with situations involving chronic problems of abuse and neglect: initial level of severity of potential for abuse and neglect; dual-parent status; a large number of children at the time of intervention (3.13 times more risk of chronicity for large families); the fact that as a child the mother herself had been placed in a foster home (3.7 times more risk); that she had been sexually abused (3.5 times more risk); and that as an adolescent she had run away from home (3.02 times more risk). Our results indicate that mothers who have a combination of more than eight risk factors are four times more likely to be in the chronic group.     

INTERNATIONAL PARENTAL CHILD ABDUCTION: WHY WE NEED TO EXPAND CUSTODY RIGHTS PROTECTED UNDER THE CHILD ABDUCTION CONVENTION

The Child Abduction Convention, an international treaty, protects custody rights internationally among its member states by providing a remedy of return in cases where a child was wrongfully removed in violation of a parent's custody right. There is no such remedy for the violation of a parent's access (or visitation) rights. A ne exeat clause in a child custody agreement restrains a custodial parent from removing a child from a predetermined jurisdiction (such as a particular country) and can be issued when there is a risk that the custodial parent might flee to another country with the child(ren). Currently there is a circuit split within the United States as to whether a ne exeat right coupled with the right of access should equal a protected custody right under the Convention. Most international courts protect the ne exeat right under the Convention; however some do not. A ne exeat right should convey a protected custody right for policy reasons. The beneficial implications of a ne exeat right creating a protected custody right under the Child Abduction Convention clearly outweigh the detriments. While there is no instant solution to the inconsistencies among various courts in interpreting the Child Abduction Conventions’ scope in regard to a ne exeat right, there are ways to resolve the problem. If consistency in judicial interpretation cannot be achieved, a movement needs to be initiated to create a protocol to the Child Abduction Convention to further explain the scope of custody rights and ne exeat rights under the Convention.     

刑事非法实物证据的定义及分类

构建刑事非法实物证据的排除规则是当下法学界一个热点问题，不同学者对此有着不同见解。造成学界在构建排除规则不统一的原因主要为：对刑事非法实物证据的定义认识不统一以及对构建刑事非法实物证据排除规则的理论基础没有全面认识。对造成上述状况的原因之一即刑事非法实物证据的定义进行尝试，并对刑事非法实物证据作一个分类，可以为学界在构建刑事非法实物证据排除规则时提供参考。     

滥用职权罪的立法价值及相关问题思考

Childhood Sexual Abuse and HIV Risk Among Men Who Have Sex with Men: Initial Test of a Conceptual Model

Childhood sexual abuse has been associated with HIV transmission risk behavior in men who have sex with men. This study examined an adapted model that was originally developed to explain the relationship between childhood sexual abuse and HIV risk behavior among women in a sample of men who have sex with men. Men attending a large gay pride event (n=647) completed anonymous surveys that assessed demographic characteristics, childhood sexual abuse, symptoms of dissociation, trauma-related anxiety, borderline personality characteristics, hopelessness, substance use, and sexual risk behavior. A latent variable partial least squares analysis was conducted to test the interrelationships between childhood sexual abuse, exchanging sex for money or drugs, emotional disturbances, drug use, substance use in the context of sexual behavior, and sexual risk behavior. The model fit the data well and accounted for 10% of the total variance in sexual risk behavior. History of childhood sexual abuse predicted exchanging sex for money or drugs and this relationship was partly accounted for by active drug use. Substance use proximal to sexual behavior also emerged as a key factor in predicting sexual risk behavior. Findings from this study, therefore, indicate a direct association between history of child sexual abuse and high risk for HIV infection related to engaging in sex trade.     

Continuities in marital violence

Marital violence studies of clinical populations of battered women indicate that, over time, violence becomes an habitual strategy for resolving conflicts resulting in escalation in frequency and severity of violence. This study examines the issue of continuity of marital violence among a national probability sample of female victims and male offenders. Findings indicate that among the general population, approximately one-half of all marital violence is suspended over a three-year period. Predictors of marital violence continuity were also investigated in an exploratory way.     

Sex differences in the experience of child sexual victimization

This study analyzed 390 (303 girls and 87 boys) cases of child sexual abuse to understand sex differences in child sexual victimization. Analyses focused on three domains that have received considerable empirical attention: victims' relationships with the offender, type and extent of abuse, and disclosure. Findings largely replicated previous efforts that reported sex differences in terms of victims' relationships with offenders. Although results also replicated previous findings about sex differences in disclosure patterns, these sex differences were minor in comparison with similarities in the way most instances of abuse were eventually identified. In terms of type and extent of abuse, results were the opposite of previous findings: girls, not boys, were the victims of more physical injury, violent threats, and use of force; and girls, not boys, were more likely to have physically resisted abuse. Divergences in findings were interpreted in terms of memory biases and social forces operating differently on the sexes.
