评估——高职院校改革与发展的助推器

高职高专院校人才培养工作水平评估,是我国高职教育改革与发展的内在要求,是政府依法行政、学校依法办学的重要举措.从实践效果看,评估有力地促进了学校教育教学观念的转变,办学思路的清晰,办学条件的改善,教学改革的深化,师资队伍的加强和教育管理的规范,实现了学校更好更快的发展.要巩固发展评估的成果,必须高度重视评估的整改工作,建立起评估的长效机制,不断推进高职院校的发展.     

Relationship between hyperuricemia and metabolic syndrome

Objective: To investigate the relationship between metabolic syndrome and hyperuricemia. Methods: A total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as ≥7 mg/dl (in men) or ≥6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. Results: (1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia odds ratio (OR)=1.634, P=0.000. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia. Conclusion: Hyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome.     

新世纪英国中等教育普通证书考试改革

自《1988年教育改革法》颁布实施之后,英国中等教育证书考试成为了对结束义务教育阶段的中学生的知识、技能水平的全面鉴定。在新世纪,英国中等教育证书考试受到人们越来越多的关注,但同时又面临诸多如质量下降、学业成绩差距拉大等新的挑战。本文通过对新世纪英国政府重要教育报告的分析,揭示英国政府对中等教育普通证书考试改革的重要举...     

民族高校细胞生物学实验教学改革探索

为了进一步培养民族高校学生的实验技能,在细胞生物学实验课程教学中,实验课教学小组通过不断改革教学方法,适应新的教学体系,及时调整实验教学内容和形式,以及建立完善的成绩评定体系,把好教学质量关,充分发掘学生的潜能,增强学生学习的自信心和兴趣,从而达到提高学生实验技能的目的.通过对近4年的细胞生物学实验成绩的分析,结果显示,实验对绝大多数学生在提高专业技能、培养独立工作能力、提高分析问题和解决问题能力、提高自主学习意识和能力、增强团队协作意识等方面有很大帮助.

论民主教育的目的与原则——自由主义政治哲学的视角

自治与权利平等是民主的基本属性。作为政治制度的民主,赋予公民平等的权利,信任公民的自治能力。民主的属性决定了民主教育不仅仅是一种公民教育,其根本目的是促使人成为自由、平等的人。民主的属性与价值追求决定了民主教育需要遵循自由原则、平等原则和教育与生活相统一原则。

Tribology Performance and Adhesive Strength Evaluation of TiAlSiN Coating

Scratch test and friction test were performed to evaluate the internal and external interface behaviors of TiAlSiN coating, respectively. The critical compressive and shearing stress of coating failure during scratch test were calculated and the values are 30.84 MPa and 4.98 MPa respectively. The average friction coefficients of TiAlSiN coating against 2Cr12Ni4Mo3VNbN steel are 0.70 (sliding speed 50 m/min), 0.63 (sliding speed 100 m/min), and 0.81 (sliding speed 150 m/min). The elements diffusion was analyzed by EDS. Al and Si element of coating material diffuse to the steel disc, except Ti element. The oxidation decreases with the increase of sliding speed, but the adhesion increases with the increase of sliding speed. More Al element diffuses to the steel disc at the high sliding speed, but the diffusion of Si element keeps almost constant at different sliding speeds.     

“序换”格续貂

根据谭永祥先生1983年首创的序换辞格论述,结合近期的语言材料,用吴士文辞格结构理论,对序换格进行了分析研究。以语法单位为标准划分出序换格的类别,并归纳出序换格的修辞作用,从而进一步认识这个比较常见常用的修辞手段。
