The Effect of Loans on the Persistence and Attainment of Community College Students

This study informs public policies regarding the use of subsidized loans as financial aid for community college students. Using logistic regression, it analyzes the National Center for Education Statistics’ Beginning Postsecondary Students (BPS 90/94) data to predict persistence to the second year of college and associate’s degree attainment over five years. During the period under study, loans did not contribute to higher persistence and attainment rates. Loans are observed to have a negative effect on persistence and no effect on degree attainment. Estimates of the interaction effects of borrowing and income status are insignificant but demonstrate the need for further testing. The findings are attributed to a combination of the high uncertainty of degree completion among community college students and the negative affective component of indebtedness.

It has also appeared as a working paper of the Institute for Higher Education Law and Governance at the University of Houston, Texas (IHELG Monograph 01–07).This paper is based upon work supported by the Association for Institutional Research, the National Center for Education Statistics and the National Science Foundation under Association for Institutional Research Grant No. 99-128-0.     

高职院校助困工作存在的问题与对策

高职贫困生是高职院校的特殊群体,如何强化贫困生的界定与管理工作,是做好助困工作的前提。建立以“助学贷款为主,奖、补、助、减、缓为辅”的多元化助学解困体系。加强诚信教育,完善国家助学贷款政策,改进奖学金、助学金制度,健全勤工助学及贫困生基金助困运行机制,是物质解困的关键;而加强贫困生正视逆境、自强自立的教育,克服自卑心理,树立自立意识,则是精神解困的根本。     

论国家助学贷款补贴政策的生成基础

助学贷款是一种具有公益性的金融产品,市场并不能对其起到充分的调节作用,其突出表现是助学贷款的“贷款难”和“回收难”问题。在这种情况下,公共财政对助学贷款进行补贴,不但可以推动助学贷款发展,而且可以优化教育资源配置,促进收入再分配和宏观经济发展。因此,公共财政对助学贷款进行补贴,既是助学贷款发展的现实需求所致,也是公共财政履行自身职能的必然要求。     

小学语文课外阅读中的价值观问题及对策

目前小学语文阅读中开放性题目的设计及教学对情感态度价值观目标的实现并不是很理想。新课标要求"培养学生高尚的道德情操和健康的审美情趣,形成正确的价值观和积极的人生态度,是语文教学的重要内容",但是小学语文阅读中存在着阅读文本陈旧、提问方式单一、讲解刻板等问题。所以在阅读教学中需要教科书编写者及教师共合作让阅读文本生活化、问题设计多样化,问题呈现情境化及教师鼓励多样化。同时家庭、学校和社会共同合作帮助学生树立正确价值观。     

中国-东盟自由贸易区背景下我国跨境教育政策研究

在全球化背景下,高等教育的跨境交流与合作成为了我国教育事业走向国际化的重要渠道。我国与东盟之间的文化教育交流在随着中国-东盟自由贸易区建成之后更加频繁。但目前由于政治经济原因,加上跨文化的障碍,使得我国与东盟跨境教育面临例如学位不能互相认证。在当前形势下发展中国与东盟的跨境教育,要通过跨境教育政策的完善,合作机制的深化改革来实现。     

Effect of methyl mercury induced free radical stress on nucleic acids and protein: Implications on cognitive and motor functions

Mercury pollution and acute neurotoxicity of mercury is well known. The recent reports suggest the adverse effect of low dose mercury, though the available literature is still silent on its mechanism. This study was therefore undertaken to probe the effect of low dose methyl mercury induced heavy metal toxicity on free radical stress and its impact on behaviour of male albino rats. Male albino rats were exposed to 1 mg/kg body wt of methylmercury chloride for seven days, on day 8 they were tested for motor and memory functions. They were sacrificed later for biochemical estimations for rate of lipid peroxidation, nucleic acids, proteins in cerebrum, cerebellum and brain stem. There was an increase in the rate of lipid peroxidation showing methyl mercury induced free radical stress. The motor and memory functions demonstrated a clear decline, besides there was a lowering in the levels of nucleic acids and proteins as compared to controls. The results are important in view of recent reports that methyl mercury induced free radical stress results in early ageing and may serve as an initiating factor more specifically for neurodegenerative disorders like Alzeihemer's disease and dementias. The current findings support the notion that incorporating dietary antioxidants like curcumin, ascorbic acid and α-tocopherol in routine diet from early age may help combat the risk of developing such disorders in ensuing years.     

基于看跌期权组合价值最大化的银行资产优化模型

银行危机的实质在于资产配置失误,资产优化配置事关银行的生存和发展。本文以银行债权组合价值最大化为目标函数,以组合风险价值VaR为约束条件控制资产组合风险的大小,建立了看跌期权组合价值最大化的银行资产分配模型。本模型主要特色与创新是通过卖出看跌期权的组合价值来客观地反映企业价值影响贷款清偿能力的本质属性。     

Evaluation of Oxidative Stress and hsCRP in Polycystic Ovarian Syndrome in a Tertiary Care Hospital

PCOS is a heterogeneous endocrine disorder with diverse clinical presentation. Oxidative stress plays a key role in the pathophysiology of this disease. Serumhigh sensitive C-reactive protein (hsCRP), a marker of chronic low grade inflammation, is indicative of future development of cardiovascular disease. Our aim is to evaluate the oxidant status and hsCRP levels in PCOS. The study involved 61 cases and 61 controls in the age group of 18–40 years diagnosed with PCOS. Erythrocyte malondialdehyde (MDA), superoxide dismutase (SOD), serum hsCRP, gonadotrophins, thyroid stimulating hormone, prolactin, glycemic status and lipid profile were estimated. Erythrocyte MDA (p < 0.001), SOD (p = 0.007) and serum hsCRP (p < 0.001) were significantly elevated in PCOS patients than controls. Oxidative stress is present in women with PCOS along with elevated hsCRP.     

图书借阅量配额管理困境的原因及对策

图书借阅量应具备一定的＂质量＂,但目前其配额数量保守、配额依据缺失、配额时限固定给图书借阅造成了不良影响。究其原因在于重藏轻用的传统观念、读者阅读的多样诉求、滞后的图书借阅技术、不太友好的图书借阅环境等。需要从树立藏书与利用的正确观念、升级图书馆管理系统的借阅功能、重新定位图书馆的角色等方面采取措施加以解决。参考文献8。     

学术文献开放访问和图书馆的应对策略

“开放访问”是近年来兴起的,目的是通过自归档和开放访问期刊等模式,促使学术论文经因特网向全社会免费开放。它具有提供全文、提供网络典藏、免费访问使用、没有授权限制、质量高等特征。参考文献12。
