We examined whether sexual attitudes of adolescents were related to their self-reported sexual risk behavior by analyzing survey data from 1,052 boys and girls aged 14 to 17 years from a low income, urban community. Sexual behavior norms that may increase sexually transmitted infection/HIV risks in youth were sanctioned more by males and by sexually experienced youth, but their attitudes were unassociated with either their age or race/ethnicity. Endorsement was correlated with greater intention to have sexual intercourse among all youth. Among sexually experienced participants, it was associated with earlier sexual debut, more partners, and less intention to use condoms but not with the number of unprotected sexual episodes in the prior six months. Sexual attitudes of youth may conflict with initiation and maintenance of safer sex practices, making them vulnerable to HIV and other sexually transmitted infections. Risk reduction interventions for adolescents should address this.  相似文献

Action plans have been shown to improve transfer of learning and have proven an effective tool in training evaluation. This study describes how action planning was simply and successfully adapted to a preexisting curriculum with few additional resources. The decision to use participant action planning, the administration of it, and the participants' and the sponsor's responses are discussed, along with suggestions for future human performance technology research.  相似文献

This study determines the relative difficulty and associated strategy use of arithmetic (addition and subtraction) story problems when presented in American Sign Language to primary level (K-3) deaf and hard-of-hearing students. Results showed that deaf and hard-of-hearing students may consider and respond to arithmetic story problems differently than their hearing peers, with the critical dimension in problem difficulty being based on the operation typically used to solve the problem, not the story within the problem. The types of strategies used by the students supported the order of problem difficulty. The visual-spatial nature of the problem presentation appeared not to assist the deaf and hard-of-hearing students in solving the problems. Factors that may have contributed to this pattern of problem difficulty are discussed so that educators can better align mathematics instruction to the thinking of the deaf child.  相似文献

Organizations need high levels of human performance from all personnel, including leaders. Unfortunately, standard organizational practices in selecting and promoting leaders reinforce behaviors that interfere with high performance from them and those they supervise. The leap from current performance levels to high performance must occur in incremental steps based on a theory of management that requires nothing less than cultural and personal change. This article defines the term “KAIZEN” and describes the changes leaders must make in their attitudes and behavior if they are to create continuously improving organizations.  相似文献
