OBJECTIVE: To explore the relationships between psychological symptoms and thyroid hormone levels in adolescent girls who had experienced the traumatic stress of sexual abuse. METHOD: The study design was cross-sectional/correlational. Subjects (N=22; age range=12-18 years) had their blood drawn, and they completed 2 psychological tests (depression and general distress/posttraumatic stress disorder [PTSD]). A pediatrician completed a sexual abuse questionnaire after reviewing law enforcement and Child Protective Services reports and conducting forensic interviews and medical examinations. RESULTS: Girls' average free T4, total T4, free T3, total T3, and TSH levels were within age-specific laboratory reference range limits, as were most individual concentrations. The strongest correlations (p<.05) were between free T3 and PTSD total score (-.50), PTSD-avoidance/numbing (-.49), and general distress (-.48); and between total T3 and depression (-.46), general distress (-.45), and PTSD-arousal (-.44). CONCLUSIONS: Our findings support one of the two contemporary models of the relationships between thyroid hormones (i.e., free and total T3) and psychological symptoms (i.e., depression, general distress, and PTSD)--one of "shutting down" (vs. "activation") in the face of trauma.  相似文献   

Challenging Educational Assumptions: Lessons from an Italian-American collaboration     

Mara Krechevsky  Janet Stork 《Cambridge Journal of Education》2000,30(1):57-74

In this paper, the authors argue that in order to create a curriculum of the future, we need to re-evaluate at least four key assumptions about teaching and learning that have guided educational decisions in the past. These assumptions are: learning is the result of individual, rather than group, activity; teachers are consumers, rather than generators, of theory; assessment is concerned with evaluating learning outcomes, rather than learning processes; teaching and learning are primarily cognitive, rather than aesthetic, ethical or affective, acts. Drawing on recent cross-cultural research, the authors use the example of the municipal pre-schools and infant-toddler centres of Reggio Emilia, Italy, to challenge these assumptions and suggest alternative ways for imagining classrooms of the future.  相似文献   

A partnership to promote teacher preparation for inclusive, urban schools: four voices     

Donna Sobel  Nancy French  Janet Filbin 《Teaching and Teacher Education》1998,14(8):793-806

This article describes a unique partnership between a university and an urban school district. University students complete a one-year internship. Major stakeholders provided evaluation data which are shared in this article. The data from this investigation confirmed our belief in the value of an immersion program in a fully inclusive urban setting. The authors describe extended research efforts as well as make recommendations for future partnership investigations.  相似文献

Precision of age norms in tests used to assess preschool children     

Janet E. Spector 《Psychology in the schools》1999,36(6):459-471

This study investigated normative precision in 14 preschool tests representing four domains: cognitive, language, adaptive behavior, and early academic skills. The purpose was to explore the consequences of using tests with more‐ vs. less‐precise age norms to identify disabilities in preschool children. As expected, on tests with more precise norms, standard scores associated with the same raw score shifted gradually across age groups. On the other hand, tests with less precise norms showed more dramatic standard score shifts across age groups. Examination of the degree of shift found in each test indicated that many preschool tests have norm tables that are potentially problematic for diagnosing disabilities, particularly for children near norm group cut‐off ages. On high stakes tests, an optimal span is one to three months. This standard can be achieved by using interpolation and/or increasing the size of norming samples at the preschool level. © 1999 John Wiley & Sons, Inc.  相似文献   

Teacher knowledge: The relationship between caring and knowing   总被引：1，自引：0，他引：1  

Kathie Webb  Janet Blond 《Teaching and Teacher Education》1995,11(6)

While everyone acknowledges the importance of the “caring teacher,” little acknowledgment of caring as an issue exists at the level of educational policymaking. This paper presents teacher and researcher stories which describe a teacher's knowledge in practice and argues for recognition of an epistemological role for caring in teaching. The teacher's narratives describe what she knows from caring and being in relationship with her students - her relational knowing (Hollingsworth et al., 1993, 1994)- and how this knowledge alters her pedagogy and the curriculum that is constructed with each student. Caring for the person (Noddings, 1984, 1992) is revealed as central to what the teacher knows. The findings of this research suggest that for the teacher, the relationship between caring and knowing is complex and involves a constant reflective process. In attempting to situate caring within existing theories for teacher knowledge, Elbaz' (1983) structures are found to be too neat and the boundaries too well defined. A construct of teacher knowledge as relational and dynamic is described. This builds upon Lyons' provisional characterization of the epistemological relationship between students and teachers as nested knowing: “that is, students and teachers are considered to have nested, interacting epistemological perspectives” (1990a, p. 162). In this view, knowledge is not limited to what one person knows, but the intersection where the knowing of two persons in-relation overlap and the consequences for student learning (and teacher development) when one of those persons is a teacher.  相似文献   

Prevalence and correlates of physical fitness testing in U.S. schools--2000     

Morrow JR  Fulton JE  Brener ND  Kohl HW 《Research quarterly for exercise and sport》2008,79(2):141-148

Because of the perceived lack of youth physical fitness and/or concerns for increased obesity, physical education teachers are interested in youth fitness and physical activity levels. Statewide mandates are being developed that require school-based teachers to complete physical fitness testing. Data from the nationally representative School Health Policies and Programs Study 2000 were analyzed to investigate the prevalence of fitness testing and the professional characteristics of fitness test users. Data were collected with teachers of either randomly selected classes in elementary schools and randomly selected required physical education courses in middle/junior high and senior high schools (N = 1,564). The prevalence of fitness test use is 65% across all school levels. Variables associated with physical fitness test usage were professionally oriented. Results showed that teachers in secondary schools (odds ratio [OR] = 2.25, 95% confidence interval [CI] = I.18-4.27), those with degrees in physical education/kinesiology-related disciplines (OR = 2.01, 95% CI = 1.11-3.63), and those who had completed staff development on physical fitness testing (OR = 3.22, 95% CI = 1.86-5.60) were more likely than respondents without these characteristics to engage in physical fitness testing. Results changed little when separate analyses were conducted for classes/courses in districts requiring versus not requiring fitness testing. Financial variables, including fitness-oriented facilities available, metropolitan location, and discretionary expenditures per student, were not associated with fitness test use. Results provided national prevalence of school-based physical fitness testing use in the U. S. and conveyed information about those who currently use physical fitness tests.  相似文献   

Examining relative age effects on performance achievement and participation rates in Masters athletes   总被引：2，自引：0，他引：2  

Medic N  Starkes JL  Young BW 《Journal of sports sciences》2007,25(12):1377-1384

Although the relative age effect has been widely observed in youth sports (Musch & Grondin, 2001), it is unclear whether it generalizes across the lifespan. The purpose of this study was to examine the relative age effect among a population of Masters athletes using archived data. Two successive studies examined the frequency of record-setting achievements (Study 1) and the frequency of participation entries (Study 2) at the US Masters track-and-field and swimming championships as a function of an individual's constituent year within any 5-year age category. Results of Study 1 indicated that the probability of setting a record increased if Masters athletes were in the first year, and decreased if they were in the third, fourth or fifth year, of an age category. Results of Study 2 indicated that the likelihood of participating in the National championships increased if Masters athletes were in the first or second year, and decreased if they were in the fourth or fifth year, of an age category. We highlight and discuss potential advantages afforded to Masters athletes who are relatively younger than their peers in the same 5-year age category.  相似文献
