OBJECTIVE: The present study evaluated the association between women's health and physical and sexual abuse suffered before age 18. METHODS: A total of 3,568 randomly sampled insured women ages 18-64 completed a telephone interview to assess history of physical only, sexual only, or both physical and sexual abuse before age 18 (Behavioral Risk Factor Surveillance System); and current health (Short Form-36, Center for Epidemiologic Studies-Depression, Presence of Symptoms surveys). Adjusted analyses compared the health of women with physical abuse only, sexual abuse only, or physical and sexual abuse to the health of women without these abuse histories. RESULTS: Poorest health status was observed in women with a history of both physical and sexual child abuse compared to women without these abuse histories. In models that adjusted for age and income, women with both abuse types had increased prevalence of depression (prevalence ratio, 2.16), severe depression (PR, 2.84), physical symptoms (PR range, 1.33 for joint pain to 2.78 for nausea/vomiting), fair/poor health (PR, 1.84), and lower SF-36 scores (3.15-5.40 points lower). Women with physical abuse only or sexual abuse only also had higher prevalence of symptoms and lower SF-36 scores but the associations were not as strong. CONCLUSIONS: This study adds to the literature showing a graded association between multiple adverse events in childhood and adult health.  相似文献

Researchers have found that teacher preparation programs are not universally preparing teacher candidates in concepts associated with the alphabetic principle. Yet, the majority of students with reading disabilities or who struggle with beginning reading have difficulty with phonology and concepts associated with the alphabetic principle. The purpose of this study was to examine the efficacy of a series of multimedia modules on participants' (N = 76) knowledge and skills related to early reading instruction. The multimedia modules covered basic literacy concepts primarily related to phonology and phonics. Results from the experimental, control-group design indicated that the modules were successful in teaching foundational literacy constructs to participants. Thus, multimedia modules may be a promising avenue for providing instruction for teacher candidates. Additional research, however, is needed to ensure mastery of knowledge and to evaluate how principles of effective instruction can guide multimedia module use by teacher educators.  相似文献

STEM教育能够发展学科知识和智力技能,这对于推动创新从而应对全球经济、社会和环境挑战是十分重要的。在全球化和数字技术颠覆传统科学教育的情况下,STEM教育的能力也是年轻人掌控就业主动权的关键。科学中心在直接实施STEM教育以及间接提升社区对STEM重要性认识的方面发挥着重要作用。本文主要阐述三个问题:亚太地区国家实行STEM教育的现状如何?新的就业环境如何影响年轻人对STEM教育能力方面的预期和他们的要求是什么?科学中心如何优化其对STEM的贡献?  相似文献

Background:Developing appropriate concussion prevention and management paradigms in middle school(MS)settings requires understanding parents’general levels of concussion-related knowledge and attitudes.This study examined factors associated with concussion-symptom knowledge and care-seeking attitudes among parents of MS children(aged 10-15 years).Methods:A panel of 1224 randomly selected U.S.residents,aged ≥18 years and identifying as parents of MS children,completed an online questionnaire capturing parental and child characteristics.The parents’concussion-symptom knowledge was measured using 25 questions,with possible answers being“yes”,“maybe”,and“no”.Correct answers earned 2 points,“maybe”answers earned 1 point,and incorrect answers earned 0 point(range:0-50;higher scores=better knowledge).Concussion care-seeking attitudes were also collected using five 7-point scale items(range:5-35;higher scores=more positive attitudes).Multivariable ordinal logistic regression models identified predictors of higher scores.Models met proportional odds assumptions.Adjusted odds ratios(aORs)with 95%confidence intervals(95%CIs)(excluding 1.00)were deemed statistically significant.Results:Median scores were 39(interquartile range:32-44)for symptom knowledge and 32(interquartile range:28-35)for care-seeking attitude.In multivariable models,odds of better symptom knowledge were higher in women vs.men(aOR=2.28;95%CI:1.71-3.05),white/non-Hispanics vs.other racial or ethnic groups(aOR=1.88;95%CI:1.42-2.49),higher parental age(10-year-increase aOR=1.47;95%CI:1.26-1.71),and greater competitiveness(10%-scale-increase aOR=1.24;95%CI:1.13-1.36).Odds of more positive care-seeking attitudes were higher in white/non-Hispanics vs.other racial or ethnic groups(aOR=1.45;95%CI:1.06-1.99)and in older parental age(10-year-increase aOR=1.24;95%CI:1.05-1.47).Conclusion:Characteristics of middle school children’s parents(e.g.,sex,race or ethnicity,age)are associated with their concussion-symptom knowledge and care-seeking attitudes.Parents’variations in concussion knowledge and attitudes warrant tailored concussion education and prevention.  相似文献

通过对梅洛庞蒂知觉理论的阐述,概括出其哲学理论:身体通过感觉 的综合活动来理解世界并以意义来表达世界;人的大部分活动是前反思的,其美学观点集中 于“美是由最小的知觉所阐发的体现行为”。其哲学的核心命题就是具象的首要性,同时, 文章还指出梅洛庞蒂理论的缺陷。本文是《批判美学与后现代主义》中的一章。  相似文献

Although undergraduates have long held a role as teaching assistants for introductory science courses at liberal arts colleges and universities, educational institutions often do not provide these students with opportunities to explore science teaching and pedagogy. At Brandeis University, we designed an internship course to help increase the motivation, understanding, and knowledge of teaching pedagogy for undergraduate teaching assistants that is offered concurrently with their teaching responsibilities. Weekly sessions with faculty mentors are guided by readings in current science education literature, and throughout the semester students are asked to develop new course material based on the pedagogical frameworks discussed. To evaluate the effectiveness of this course, we surveyed students at the close of the semester. We found an overall increase in student confidence levels with regard to teaching and better awareness of the difficulties faced in science education. All students who participated in the course expressed interest in participating in future educational internships. We believe that the Educating Young Educators internship has the potential to be a catalyst for personal and professional growth from a novice into an informed young educator.  相似文献
