近二十年国内学分银行研究综述

目前,国内关于学分银行的研究主要经历了理论探索、建设实践和完善制度这三个阶段,相应的研究热点也围绕这三个阶段展开.如今国家正在加大力度建设学分银行制度,对于它的研究也应更深入,以便更快更准地掌握学分银行制度的发展现状.基于此,对学分银行制度进行研究,并提出以下几点建议:追溯基础理论,界定概念;加强国家顶层设计,健全管理体系;突破制度研究障碍,整合实践成果;纳入终身教育体系,打破领域壁垒.     

Genetic Polymorphism of Angiotensin II Type 1 Receptors and Their Effect on the Clinical Outcome of Captopril Treatment in Arab Iraqi Patients with Acute Coronary Syndrome (Mid Euphrates)

Genetic variation in the angiotensin II type 1 receptor (AT1R) has an important effect on the outcome of acute coronary syndrome (ACS) initiated treatment with captopril. This study aims to investigate the impact of genetic polymorphism of AT1R (rs5186 and rs275651) on the ACS outcome in Iraqi patients treated with captopril. A total of 250 Iraqi individuals with ACS were included in this case—control study and they were divided into two study groups; Study group 1 included 125 participants who were prescribed captopril, 25 mg twice daily and study group 2 included 125 participants who received no captopril as part of their ACS treatment (control study). The AT1R gene (rs5186) CC genotype was found to be associated with ST-elevation myocardial infarction (STEMI) (Odd’s ratio (O.R) = 1.2, P = 0.7), while AC was associated with Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) (O.R = 1.2, P = 0.8). AC genotype is more prone to have Percutaneous coronary intervention (PCI) after ACS attack (O.R = 1.2, P = 0.6). CC genotype had a risk to get less improvement (O.R = 1.6, P = 0.5), so might require higher doses of captopril during acute coronary insult. The AT1R gene (rs275651) AA genotype was associated with UA (O.R = 1.3, P = 0.9). AA and AT genotypes were more prone to have PCI after ACS attack (O.R = 3.9 P = 0.2, O.R = 3.5, P = 0.3 respectively) and thus requiring higher doses of captopril. We conclude that the AT1R rs5186, rs275651 genetic polymorphisms might partially affect the clinical outcome of ACS patients treated with captopril and might have captopril resistance which requires higher doses.     

An analysis of review content and reviewer variables that contribute to review helpfulness

Review helpfulness is attracting increasing attention of practitioners and academics. It helps in reducing risks and uncertainty faced by users in online shopping. This study examines uninvestigated variables by looking at not only the review characteristics but also important indicators of reviewers. Several significant review content and two reviewer variables are proposed and an effective review helpfulness prediction model is built using stochastic gradient boosting learning method. This study derived a mechanism to extract novel review content variables from review text. Six popular machine learning models and three real-life Amazon review data sets are used for analysis. Our results are robust to several product categories and along three Amazon review data sets. The results show that review content variables deliver the best performance as compared to the reviewer and state-of-the-art baseline as a standalone model. This study finds that reviewer helpfulness per day and syllables in review text strongly relates to review helpfulness. Moreover, the number of space, aux verb, drives words in review text and productivity score of a reviewer are also effective predictors of review helpfulness. The findings will help customers to write better reviews, help retailers to manage their websites intelligently and aid customers in their product purchasing decisions.     

关于中国男篮在世界大赛中成绩滑坡的原因剖析

采用文献资料与理论分析等方法 ,对中国男篮在第 2 7届奥运会和第 14届男篮世锦赛上攻、防技术资料进行分析研究 ,发现中国男篮整体实力确有提高 ,尤其是内线实力明显增强。但由于我国对篮球本质认识上的偏差 ,过分追求队员高度而忽视速度、战术与技术训练 ,特别是外线控球能力的培养 ,结果比赛时内、外线脱节 ,整体攻、防节奏慢 ,不仅内线实力难以发挥 ,相反丢失了过去快速、灵活的优势与特点。针对存在的问题 ,从主观认识、训练方法以及训练内容等方面提出了一些建议和改进措施。
