Oxidative injury and antioxidant vitamins E and C in Schizophrenia     

Benedicta D'Souza  Vivian D'Souza 《Indian journal of clinical biochemistry : IJCB》2003,18(1):87-90

Susceptibility of Schizophrenic patients to lipid peroxidation relative to healthy control subjects was investigated by measuring the malondialdehyde (MDA) levels in plasma. The main finding was that Schizophrenic patients were more susceptible than control subjects to oxidative damage as evident from increased MDA levels in plasma. Antioxidant levels are also depleted in Schizophrenic patients when compared to normal subjects as evident from decreased levels of vitamins E and C in the plasma. Impaired antioxidant defense and increased lipid peroxidation suggests that treatment with antioxidants (Vitamin E, Vitamin C, beta carotene) at the initial stages of illness may prevent further oxidative injury and deterioration of associated neurological deficits in Schizophrenia.  相似文献   

Attitudes toward Family Obligations among American Adolescents with Asian, Latin American, and European Backgrounds   总被引：6，自引：0，他引：6  

Andrew J. Fuligni  Vivian Tseng  & May Lam 《Child development》1999,70(4):1030-1044

This study was designed to examine the attitudes toward family obligations among over 800 American tenth ( M age = 15.7 years) and twelfth ( M age = 17.7 years) grade students from Filipino, Chinese, Mexican, Central and South American, and European backgrounds. Asian and Latin American adolescents possessed stronger values and greater expectations regarding their duty to assist, respect, and support their families than their peers with European backgrounds. These differences tended to be large and were consistent across the youths' generation, gender, family composition, and socioeconomic background. Whereas an emphasis on family obligations tended to be associated with more positive family and peer relationships and academic motivation, adolescents who indicated the strongest endorsement of their obligations tended to receive school grades just as low as or even lower than those with the weakest endorsement. There was no evidence, however, that the ethnic variations in attitudes produced meaningful group differences in the adolescents' development. These findings suggest that even within a society that emphasizes adolescent autonomy and independence, youths from families with collectivistic traditions retain their parents' familistic values and that these values do not have a negative impact upon their development.  相似文献

Exploring cultural differences in critical thinking: Is it about my thinking style or the language I speak?     

Vivian Miu-Chi Lun  Ronald Fischer  Colleen Ward 《Learning and individual differences》2010,20(6):604-616

Critical thinking is deemed as an ideal in academic settings, but cultural differences in critical thinking performance between Asian and Western students have been reported in the international education literature. We examined explanations for the observed differences in critical thinking between Asian and New Zealand (NZ) European students, and tested hypotheses derived from research in international education and cultural psychology. The results showed that NZ European students performed better on two objective measures of critical thinking skills than Asian students. English proficiency, but not dialectical thinking style, could at least partially if not fully explain these differences. This finding holds with both self-report (Study 1) and objectively measured (Study 2a) English proficiency. The results also indicated that Asian students tended to rely more on dialectical thinking to solve critical thinking problems than their Western counterparts. In a follow-up data analysis, students' critical thinking was found to predict their academic performance after controlling for the effects of English proficiency and general intellectual ability, but the relationship does not vary as a function of students' cultural backgrounds or cultural adoption (Study 2b). Altogether, these findings contribute to our understanding of the influence of culture on critical thinking in international education.  相似文献   

Effect of carbohydrate ingestion during cycling exercise on affective valence and activation in recreational exercisers     

Vivian Lee  Kay Rutherfurd-Markwick 《Journal of sports sciences》2018,36(3):340-347

Carbohydrate (CHO) ingestion enhances “feel-good” responses during acute exercise but no study has examined the effect of regular ingestion of CHO on affective valence. We investigated the effect of CHO ingestion on perceptual responses and perceived work intensity of individual exercise sessions throughout a 10-week cycling (“spin”) exercise intervention. We also assessed whether any changes in affect and/or perceived work intensity would influence health and fitness parameters. Twelve recreational exercisers (46 ± 9 years; nine females and three males) were randomly allocated to either CHO (7.5% CHO; 5 mL · kg^?1 per exercise session; n = 6; CHO) or placebo (0% CHO, taste- and volume-matched solution; n = 6; PLA) groups. Participants exercised 2 × 45-min per week, over a 10-week intervention period. Perceptual measures of exertion (RPE), affect (feeling scale, FS) and activation (felt arousal scale, FAS) were assessed after each exercise session. The FAS ratings increased over time in CHO but decreased throughout the intervention in PLA (P = 0.03). There were no differences in heart rate (P = 0.70), RPE (P = 0.05) and FS (P = 0.84) between trials. Furthermore, no changes in health and fitness parameters were observed over time or between groups. CHO ingestion enhanced ratings of activation in recreational exercisers throughout a 10-week cycling intervention.  相似文献   

Toy safety and selection     

Satomi Izumi Taylor  Vivian Gunn Morris  Cosby Steele Rogers 《Early Childhood Education Journal》1997,24(4):235-238

Toys can be used to promote children's cognitive, physical, motor, language, social, and emotional development. Safety and developmental appropriateness are of the utmost importance when selecting children's toys. Parents and teachers and other helping professionals need to teach children the safe use of toys to prevent toy-related accidents. Obtain additional information regarding toy safety by calling the U.S. Consumer Product Safety Commission at 1(800)638-CPSC.  相似文献

Medical students at the Schulich School of Medicine and Dentistry at The University of Western Ontario in London, Ontario, Canada, learn clinical facts about the hepatobiliary system as transplant surgeon Dr. Vivian McAlister (at the far right) demonstrates Whipple's procedure in the anatomy laboratory. In this issue of ASE, Ullah and colleagues describe an extracurricular student initiative known as the Surgically Oriented Anatomy Program (SOAP), which aims to deliver anatomy teaching from a surgical perspective through the philosophy of “education through recreation”.  相似文献   

Learning surgically oriented anatomy in a student-run extracurricular club: an education through recreation initiative     

Ullah SM  Bodrogi A  Cristea O  Johnson M  McAlister VC 《Anatomical sciences education》2012,5(3):165-170

Didactic and laboratory anatomical education have seen significant reductions in the medical school curriculum due, in part, to the current shift from basic science to more clinically based teaching in North American medical schools. In order to increase medical student exposure to anatomy, with clinical applicability, a student-run initiative called surgically oriented anatomy prosectors (SOAP) club was created within the extracurricular program at the Schulich School of Medicine and Dentistry, The University of Western Ontario, London, Canada. SOAP invites surgeons and residents from various surgical specialties to demonstrate, on a cadaver, a surgical procedure of their choosing. During the demonstration, the anatomy, as it relates to the surgical procedure, is discussed. The students then break into smaller groups to examine the relevant anatomy on the cadavers, during which time the discussion is broadened. The group continues the conversation in a social environment with refreshments. SOAP is one of the most popular extracurricular clubs with 65% of first and second year medical students registered as members. The high demand for SOAP, along with the positive participant feedback, may be due to its utilization of the principle of education through recreation, which seeks to provide opportunities for learning seamlessly throughout all facets of life. It also demonstrates the desire, amongst certain medical students, to learn applied anatomy, particularly within a surgical context.  相似文献   

Forecasting performance of grey prediction for education expenditure and school enrollment     

Hui-Wen Vivian Tang  Mu-Shang Yin 《Economics of Education Review》2012

GM(1,1) and GM(1,1) rolling models derived from grey system theory were estimated using time-series data from projection studies by National Center for Education Statistics (NCES). An out-of-sample forecasting competition between the two grey prediction models and exponential smoothing used by NCES was conducted for education expenditure and school enrollment under the assumption that grey prediction was as promising as NCES's forecasting technique in dealing with univariate time-series data while some other determinants of the variables under examination were excluded. The purpose of this study, therefore, was to verify that the GM(1,1), and GM(1,1) rolling models would provide forecasts that were at least as accurate as the NCES's approach to extrapolating education expenditure and school enrollment. The findings revealed that the forecasting efficiency of GM(1,1) rolling model was superior to exponential smoothing and GM(1,1) model. The results can offer valuable insights and provide a basis for further research in model building for short-term estimation on educational statistics.  相似文献
