OBJECTIVE: This study examined the prevalence and psychological sequelae of childhood sexual and physical abuse in adults from the general population. METHOD: A national sampling service generated a geographically stratified, random sample of 1,442 subjects from the United States. Subjects were mailed a questionnaire that included the Traumatic Events Survey (TES) [Traumatic Events Survey, Unpublished Psychological Test, Harbor-UCLA Medical Center, Los Angeles] and the Trauma Symptom Inventory (TSI) [Trauma Symptom Inventory Professional Manual, Psychological Assessment Resources, Odessa, FL]. Of all potential subjects, 935 (64.8%) returned substantially completed surveys. RESULTS: Sixty-six men and 152 women (14.2% and 32.3%, respectively) reported childhood experiences that satisfied criteria for sexual abuse, and 103 males and 92 females (22.2% and 19.5%, respectively) met criteria for physical abuse. Twenty-one percent of subjects with one type of abuse also had experienced the other type, and both types were associated with subsequent adult victimization. After controlling for demographics, adult history of interpersonal violence, and other child abuse, childhood sexual abuse was associated with all 10 scales of the TSI, and physical abuse was related to all TSI scales except those tapping sexual issues. Sexual abuse predicted more symptom variance than did physical abuse or adult interpersonal victimization. Various aspects of both physical and sexual abuse experiences were predictive of TSI scores. Abuser sex, however, both alone and in interaction with victim sex, was not associated with additional TSI symptomatology. CONCLUSIONS: Childhood sexual and physical abuse is relatively common in the general population, and is associated with a wide variety of psychological symptoms. These relationships remain even after controlling for relevant background variables. 相似文献

This paper examines the ways in which segregation in schools contributes to the perpetuation of residential segregation, and the ways in which metropolitan-wide school desegregation supports housing integration. An empirical analysis of real estate advertising practices in fourteen American cities is outlined, and supplemented by a discussion of the character of real estate agent advice to homeseekers. Conclusions are drawn about the differences in the housing choice process in communities with segregated as opposed to desegregated schools. Finally, implications for urban policy are presented.The research reported here was supported by the National Institute of Education, Grant HEW-NIE G-78-0125/1. 相似文献

This paper draws on the findings of a research project funded by the Liverpool City of Learning consortium in the UK. The aim is to explore the process of introduction of ten authority wide learning networks, the impact these have on school professionals practice, the opportunities they offer for CPD and the extent to which they may impact on pupil learning. The research presented here draws on findings from a questionnaire distributed to school professionals and key issues emerging from their analysis point to the influence of national government agendas on school professionals’ interpretation of the purpose of the networks. They also point to the views of staff regarding the impact of the attainment agenda as well as the extent to which an increased emphasis on social inclusion and wider understandings of learning and achievement (which are less well represented by results-based performance monitoring) are having on their hopes for what Learning Networks might deliver. The expectations of staff of the opportunities offered by learning networks for long term professional development provide some interesting insights, and perhaps, some useful pointers as to how networks of this kind might develop in the future. 相似文献

The aim of this study was to investigate the effectiveness of a caffeine-containing energy drink to enhance physical and match performance in elite badminton players. Sixteen male and elite badminton players (25.4 ± 7.3 year; 71.8 ± 7.9 kg) participated in a double-blind, placebo-controlled and randomised experiment. On two different sessions, badminton players ingested 3 mg of caffeine per kg of body mass in the form of an energy drink or the same drink without caffeine (placebo). After 60 min, participants performed the following tests: handgrip maximal force production, smash jump without and with shuttlecock, squat jump, countermovement jump and the agility T-test. Later, a 45-min simulated badminton match was played. Players’ number of impacts and heart rate was measured during the match. The ingestion of the caffeinated energy drink increased squat jump height (34.5 ± 4.7 vs. 36.4 ± 4.3 cm; P < 0.05), squat jump peak power (P < 0.05), countermovement jump height (37.7 ± 4.5 vs. 39.5 ± 5.1 cm; P < 0.05) and countermovement jump peak power (P < 0.05). In addition, an increased number of total impacts was found during the badminton match (7395 ± 1594 vs. 7707 ± 2033 impacts; P < 0.05). In conclusion, the results show that the use of caffeine-containing energy drink may be an effective nutritional aid to increase jump performance and activity patterns during game in elite badminton players. 相似文献
