Based on Parrot's work with college students, a six‐activity acquaintance rape prevention program for first‐year high school students living in a rural South Carolina community was implemented and evaluated. The program decreased students' acceptance of rape myths compared with non‐participating students both on a scale developed by Burt and on additional items measuring acquaintance rape. Attitudes toward dating violence did not change. Research limitations are discussed, and practical suggestions for sex education are presented. 相似文献

Superoxide dismutase (SOD) activities in the human and rat RBCs and rat liver, kidney, brain and heart mitochondria as well
as cytosolic fractions were determined by the pyrogallol assay procedure with slight modifications. Measurements were carried
out in 0.1 M potassium phosphate buffer pH 8.0 and 9.2 to assess the pH stability of the SODs from various systems. Under
these conditions the SODs from different systems including RBCs exhibited differential pH stability i.e. they displayed differential
susceptibility at pH 9.2. Even in a given tissue, the mitochondrial and cytosolic SODs contents show a tissue-specific pattern.
Our results also suggest that measurements carried out at pH 8.0 may give more realistic estimates of SOD activities. 相似文献

The transition between school or college and higher education can be a challenging time for a student. Schools, colleges and universities work together in a number of ways in order to try and ease this process. However, many students still find their first-year experience difficult to adjust to, which can impact on their own development and achievement. This article documents critical reflections on a case study of a teaching, learning and research partnership currently being undertaken between a secondary school where students are taught AS and A Level psychology and a department of psychology in a post-1992 university in England. Drawing upon a social constructivist framework together with Healey’s model of the link between research and teaching, the aims of this study were to explore how undergraduate dissertation students can work with AS and A Level students on their dissertation projects. The study showed that the AS and A Level students found it an enjoyable practical experience, which they felt enhanced their understanding of university studies. The dissertation students found that the experience might be useful for postgraduate studies and future employment. This article highlights the benefits of the process but also the challenges for those involved, particularly if it was to be conducted on a larger scale. 相似文献

An experiment is reported that explored whether training in mental imagery would improve text comprehension in 9-year-old children. Two groups of children were compared: good and poor comprehenders. The groups were matched on a test of vocabulary and decoding, but differed on a comprehension test. The results showed that a three-session programme of training in imagery benefited the poor, but not the good, comprehenders, by comparison with a control group who merely answered questions about the same passages. The results are discussed in relation to possible causes of children's comprehension difficulties. 相似文献

In 1998, the Government introduced the National Literacy Strategy (NLS) in all primary schools in England in a bid to raise literacy standards. The first cohort of primary schools in the northern Local Education Authority ( n = 19) implemented the project in January 1997, the second cohort ( n = 20) began in September 1997. Each cohort consisted of three different year groups (Year 2, Year 4 and Year 6). The aim of this project was to focus upon exam results from these schools and thereby identify possible predictors of success (e.g. socio-economic status, age of pupils, teaching and learning style). We looked at differences within and between each cohort. We also carried out in-depth case studies of three northern schools. Each case-study involved interviews with key staff. The wider implications of the findings for the implementation of the NLS and for the training needs of teachers are considered. 相似文献

Oxidative stress has been proposed as a common underlying mechanism of cataractogenesis. Experimental and observational data
suggest that micronutrients like vitamin C and vitamin E with antioxidant capabilities may retard the development of age-related
cataract. Effect of these factors on lens epithelium cells, center of lens metabolic activities, is not completely elucidated.
The aim of present study was to examine the effect of vitamin C and E on surgically removed lens epithelium cells of patients
with cataract. Capsulorhexis samples were collected from 170 patients, admitted for cataract surgery. Catalase specific activity
was estimated in lens epithelium cells with and without vitamin (C or E) treatment at different concentration for different
time duration. Student’s t-test was employed for data analysis. We observed that in ex-vivo condition, a) both vitamin C and
E bring about a decrease in catalase activity in lens epithelial cells. b) vitamin C showed toxic effect at high concentration.
c) 100μM was the optimum concentration at which both vitamins showed maximum antioxidant activity. It was concluded that both
vitamin C and E has direct effect on lens epithelium cells. At optimum concentration, they can reduce oxidative stress in
these cells thus can support to prevent or delay cataract development. 相似文献

The aims of this study were to (1) propose a method for evaluating shot-putters mechanical power, (2) investigate the relationship between mechanical work of hand action force (WHAF), peak power output (PPO) of different limbs and shot-put performance and (3) show which of these two parameters (WHAF, PPO) were the most appropriate to characterize the explosive abilities of the shot-putter. Twelve junior right-handed shot-putters, practised glide technique shot-put throwers (personal best?=?13.57 ± 1.72 m), participated in this study. Arm and leg force-velocity tests were performed to measure PPO. Kinematic analysis was conducted during a shot-putting event in regular conditions to quantify the WHAF at the release moment and shot-put performance. Significant correlations were found between absolute arm and leg PPO with upper and lower muscle volumes (r?=?.67; p?=?.03; r?=?.76; p?=?.01; r?=?.74, p?=?.01; r?=?.65, p?=?.04). Positive relationships were recorded between absolute arm and leg PPO and shot-put performance (r?=?.67, p?=?.02; r?=?.81, p?=?.004, respectively). Shot-put performance was also closely related to the WHAF (r?=?.93, p?=?.0001) and release velocity parameter (r?=?.86, p?=?.001). The present results confirm that force-velocity test and WHAF constitute useful tools for assessing mechanical power in throwing. The WHAF could be considered as more suitable than force-velocity test. 相似文献
