海岛中学生心理卫生特点及相关因素分析

目的 了解海岛中学生的心理健康状况及其相关因素。方法 随机分层整群抽取海岛城镇2243名中学生，采用自制的一般情况问卷、90项症状清单及艾森克人格问卷进行测试，用SPSS软件包进行统计分析。结果 海岛城镇中学生中的非独生子女比独生子女、高中生比初中生、女生比男生、家庭居住在渔农村比居住在城镇的中学生心理健康水平要低。他们的心理障碍的发生率和SCL-90各项因子分与国内大陆某些地区的报道有所不同，本文中学生的个性特征与SCL-90各项因子分的相关分析表明海岛城镇中学生的心理健康状况与性格的内外倾向、掩饰作用呈负相关，与心理变态倾向、情绪稳定性呈正相关。本文男女生的心理障碍的发生率为16％～47％，以强迫症状为最显著。结论海岛中学生心理障碍的发生率较高，并且与大陆其它地区中学生心理健康状况有所不同。     

Prevalence of giardiasis among primary school children

Summary This cross-sectional study was conducted to investigate the prevalence of intestinal parasites among primary school children in Northern Jordan. Stool specimens were collected from 1100 children of both sexes from urban and rural schools. A questionnaire covering relevant informations was completed for each child. Wet mount preparation, formaline-ether concentration technique, and trichrome stain were prepared for the recovery and identification of parasites. Giardia lamblia was observed in 396 (36%) of the stool specimens examined. The infection rates were higher in the younger age group where several of them had diarrhoea and reported variable symptoms. The infection rates declined with age and children were asymptomatic. Rates were higher in children from the rural areas, from low income families, and it was higher in boys than girls.
Contaminated drinking water is suspected to be the major potential source of infection. The importance of the asymptomatic cases and the epidemiological factors contributing to the transmission in these areas are discussed.     

Self-directed learning in anatomy: incorporation of case-based studies into a conventional medical curriculum

This paper reports an attempt to develop self-directed learning skills in second-year medical students by introducing case-based projects into the gross anatomy course at a long-established medical school. The programme and students' responses to a questionnaire completed at the end of the year are presented. Information on the various resources used by students to find information is given. The performance of students in the case-based components of the course has been evaluated and also in the more traditional end-of-year written examination. The data confirm that students have recognized that the projects were about obtaining a deeper understanding of the anatomy, and the programme appears to have promoted the use and study of library texts.     

Undergraduate medical education in obstetrics and gynaecology in the USA and Canada, 1985

Many factors have led to a movement from the emphasis of the 1960s and 1970s on departmental expansion towards an emphasis on cost-effective undergraduate medical education emphasizing the 'art' as well as the 'science' of medicine. In January 1985 a questionnaire was sent under the auspices of the Undergraduate Education Committee of the Association of Professors of Obstetrics and Gynecology to all chairmen of departments of obstetrics and gynecology in the USA and Canada seeking their opinions about these trends and information about the educational programmes in their departments. The information from this study indicates that the chairmen are aware of and responding to this new direction in medical education. A stabilization of teaching staff and clerkship sizes and the emphasis on clinical as well as cognitive evaluation, despite recognition of the cost of the former, shows active interventions towards these ends. An emphasis on education in 'basic' as compared to 'subspecialty' areas which is independent of the subspecialty of the academic chairman also supports this trend.     

Teaching school health to undergraduate medical students

This paper describes a teaching programme for final- (sixth-) year undergraduate medical students during their 10-week term in child health. Students attend schools on two occasions and are actively involved in the physical, educational and emotional assessment of children. The advantages of the programme include active participation by the students, contact with children in a less threatening environment, learning new skills in the assessment of children, and knowledge of common screening procedures. Student evaluation of the programme has been positive.     

Perceptions of the at-risk nonsmoker: are potential intervention topics being overlooked?

This research is supported in part by Arizona Disease Control and Research Commission (ADCRC), Grant #9904 (M. Burgoon, PI). This study assesses how adolescent nonsmokers, at-risk smokers, and smokers differ in perceptions of smoking harms, benefits, and safety. While small differences exist when comparing attitudes and knowledge concerning short- and long-term benefits of smoking, large differences arise when attitudes and knowledge concerning the short-term benefits and the safety of casual smoking are compared.     

高师地理学科的环境教育

党的十六大所提出的全面建设小康社会，是一个包括政治、经济、文化、环境乃至国民素质的综合概念。它特别要求国民具有健全的环境意识，良好的环境伦理道德和高尚的环境道德行为。作为担负着提高全体国民环境素质和培养中小学环境教育教师和地方环境建设服务三重使命的高师地理学科，面临着其环境教育的课程设置、教材建设和教师队伍建设等不可回避的课题，有必要进行深入探索。     

In the Context of Risk: Supportive Adults and the School Engagement of Middle School Students*

Abstract: Many students in the United States, particularly those from lower income or racially/ethnically diverse families, are exposed to clusters of risk factors that have a negative impact on school success. This study examined the association between the number of supportive and caring adults in the home, school, and neighborhood and the school engagement of students in early adolescence. Results revealed that students who reported such supportive adults in their lives also reported higher levels of psychological and behavioral engagement with their schooling. Additionally, including measures of environmental risk factors in analytical models of the school engagement of middle school students reduced otherwise statistically significant race/ethnicity differences to nonsignificance. Implications for practice and policy are discussed.
