OBJECTIVE: This study examined specific aspects of child sexual abuse in relation to symptom severity among hospitalized patients diagnosed with bulimia nervosa. METHOD: Participants were 45 hospitalized bulimic women who reported a history of child sexual abuse. Structured interviews were conducted in order to obtain detailed information regarding specific features of the abusive event(s). Participants also completed instruments that measured depression and eating pathology. RESULTS: There were no significant differences in severity of depression or eating disturbance among women reporting differing abusive experiences including intrafamilial versus extrafamilial abuse, abuse with or without the use of physical force, one versus multiple incidents, early abuse versus abuse occurring after age 14, contact versus noncontact abuse, disclosed versus undisclosed, and combined physical/sexual abuse versus sexual abuse alone. CONCLUSION: The specific characteristics of child sexual abuse are not related to the level of symptomatology for hospitalized bulimic patients. This study suggests that differences in the nature of the abuse may not be as important as the fact that the abuse occurred in the first place. 相似文献

This article compares traditional college students' perceptions of effective teaching behaviors with nontraditional students' perceptions. A 15-item questionnaire was completed by undergraduates at a small Southeastern university. Nontraditional students viewed personality and interaction behaviors as more indicative of effective teaching, whereas traditional students focused on behaviors that potentially would enhance grades. The implications of the findings are discussed in light of techniques and approaches that facilitate the needs of both types of students.His major areas of interest include testing and counseling.

Many residence hall staff have attempted to align the academic subculture of the faculty with the opposing extracurricular subculture of students by moving closer to the academic sector. Studies at Harvard University and at Hampshire College are summarized to indicate the failure of traditional house systems or residence hall programming to successfully bridge the gap between the academic and living subcultures. It is suggested that student personnel staff should focus on their unique contribution in higher education: the facilitation of students' personal development and interpersonal communication skills. 相似文献

This paper deals with Hilbert‘s 16th problem and its generalizations.The configurations of all closed branches of an algebraic curve of degreee n are discussed.The maximum number of sheets for an algebraic equation of degree n and the maximum number of limit cycles for a planar algebraic autonomous system are achieved.The author also considers different generalizations and some related problems. 相似文献

Verbal and nonverbal responses by alleged victims of child sexual abuse were coded for length, amount of information, and the manner in which they were elicited by the interviewer. In 16 of the interviews, anatomical dolls were employed for the purposes of demonstration, whereas they were not used in another eight cases matched with respect to other characteristics of the children and the alleged events. Children interviewed with dolls provided an equivalent number of details and spoke as many words in the substantive portion of the interview as did children interviewed without dolls, and interviewers in the two groups used similar probes to elicit information. However, the average responses by the children were significantly longer and more detailed when dolls were not used. Children gave longer and more detailed responses to open-ended invitations when dolls were not used. Caution is necessary when interpreting these findings. 相似文献

This study used an ecological framework to examine predictors of delinquent behaviors among 91 sixth-grade Latino youth. Both proximal and distal contextual factors were assessed to determine their impact on various forms of delinquency, such as violent behaviors, violent thoughts, substance abuse, and general delinquency (e.g., skipping school). Attitudes toward school, mobility (number of moves to new schools and neighborhoods), and exposure to community violence were distal variables, whereas attachment to parents and attachment to peers were considered more proximal variables. Environmental experiences or exposure to distressing community violence was the strongest predictor of delinquent outcomes. The results were discussed in terms of school officials' developing linkages with the community to promote safe environments for youth. 相似文献

Although the tradition of bicameral governance is well established in Canada's universities, in no province do community colleges operate under a similar principle. In fact, there is no statutory role for college faculty in governance, either through a senate or a senate-like body. This article argues the case for greater democracy in the governance of colleges and, in doing so, analyzes the role of college governance. The conclusion reached is that, while more democratic and participatory governance may be argued on conceptual grounds, it would also improve morale, trust, and communication within the college sector. 相似文献
