A comparison of Dabrowski's overexcitabilities by gender for American and Korean high school gifted students     

Jane Piirto  Diane Montgomery  James May 《High Ability Studies》2008,19(2):141-153

The differences between US (Ohio) gifted and talented high school students and South Korean gifted and talented high school students on the Overexcitabilities Questionnaire II (OEQ II) were investigated. The OEQ II was administered to 227 Ohio identified gifted and talented high school students (M = 88, F = 139) and to 341 high school students from four specialized high schools (one for science, one for foreign language, and two for the arts) in Seoul, Korea (M = 117; F = 224). Multiple analysis of variance by gender and country revealed that Korean males and females scored higher in psychomotor OE and that US males and females scored higher in imaginational OE. No differences were found in intellectual OE, emotional OE, or sensual OE.  相似文献

Effect of antimalarials treatment on rat liver lysosomal function—Anin vivo study     

Samir P. Patel  Subhash D. Katewa  Surendra S. Katyare 《Indian journal of clinical biochemistry : IJCB》2005,20(1):1-8

Effects of treatmentin vivo with the antimalarials:chloroquine (CQ), primaquine (PQ) and quinine(Q) on lysosomal enzymes and lysosomal membrane integrity were examined. Treatment with the three antimalarials showed an apparent increase in the membrane stability. CQ treatment resulted in increase in both the ‘free’ and ‘total’ activities of all the enzymes i.e. acid phosphatase, RNase II, DNase II and cathepsin D. PQ treatment lowered the ‘free’ and ‘total’ activities of acid phosphatase and cathepsin D, but the DNase II activities increased. Treatment with Q resulted in increased ‘free’ and ‘total’ activities of RNase II and DNase II. While ‘free’ activities of acid phosphatase and cathepsin D were low; the ‘total’ activities increased significantly. Our results suggest that a generalized increase in free nucleases activities following prolonged treatment with antimalarials may lead to cell damage and/or necrosis.  相似文献

Substituting SAT II: Subject Tests for SAT I: Reasoning Tests: Impact on Admitted Class Composition and Quality     

Bridgeman  Brent  Burton  Nancy  Cline  Frederick 《Research in higher education》2003,44(1):83-98

Using data from a sample of 10 colleges at which most students had taken both SAT I: Reasoning tests and SAT II: Subject tests, we simulated the effects of making selection decisions using SAT II scores in place of SAT I scores. Specifically, we treated the students in each college as forming the applicant pool for a more select college, and then selected the top two thirds (and top one third) of the students using high school grade point average combined with either SAT I scores or the average of SAT II scores. Success rates, in terms of first-year grade point averages, were virtually identical for students selected by the different models. The percentage of African American, Asian American, and White students selected varied only slightly across models. Appreciably more Mexican American and Other Latino students were selected with the model that used SAT II scores in place of SAT I scores because these students submitted subject test scores for the Spanish test on which they had high scores.  相似文献   

战后初期苏联对华外交策略原因浅析     

徐俊武 《三明学院学报》2002,19(4):101-104

战后初期 ,苏联对华外交特征主要是承认国民党政府的合法性 ,支持蒋介石统一中国 ;另一方面 ,在东北地区则又对国共双方采取矛盾的“等距离”政策。苏联实行这一对华外交方针的原因是多方面的 ,主要受到当时中国国内复杂的形势 ,斯大林对中国国共双方斗争发展前途的错误估计 ,苏联战略重点选择的需要及斯大林对毛泽东与中国共产党的片面认识等诸多因素的影响  相似文献
