A number of social and psychological factors present in most adolescent parents place them at high risk for abusive behavior toward their children. However, current child abuse potential measures do not include adolescent samples as part of the psychometric data base. Consequently, the purpose of this study was twofold: (1) to investigate whether a Black adolescent sample would perform differently than an adult nonabusing sample on the Child Abuse Potential Inventory (CAP), and (2) to examine the relationship between history of abuse or witnessing violence to scores on the CAP. Results revealed that Black adolescents scored significantly higher than the adult normative sample on the CAP; consequently, cutoff scores need to be empirically established for adolescents. Additional analyses indicated that a history of abuse, as well as a history of witnessing violence, are associated with a high potential for abuse.  相似文献

Presented in this essay are suggestions for rewriting Roe vs. Wade, the case that resulted in the establishment of a constitutional right to abortion. Essentially, the argument is 1 of equal protection. It is suggested that abortion be viewed as presenting a problem that might be termed "the law of samaritanism" -- the law regarding obligations imposed on certain individuals to provide assistance to others. In American law it is a deeply rooted principle that an individual is ordinarily not required to volunteer assistance to another individual who is in danger or in need of aid. The argument presented maintains that if a pregnant woman is required to carry the fetus to term and deliver it, then she is being compelled to be a Good Samaritan. It is argued further that if the generally limited scope of obligations of samaritanism under current law are considered, and the special nature of the burdens imposed on pregnant women by laws forbidding abortion are also considered, the obvious conclusion is that the equal protection clause forbids imposition of these burdens on pregnant women. The argument is developed in a lengthy form and calls for an extended discussion of the law of samaritanism. The uniqueness of the abortion case also creates problems as the equal protection argument is approached, and an approach to equal protection questions is sketched.  相似文献
