大学生道德教育的接受心理及针对性措施

要提高大学生道德教育的实效性,必须研究道德教育过程中受教育者的接受心理。道德接受的过程是一个心理活动的过程,受教育者是否接受,取决于受教育者的接受心理。只有了解大学生的接受心理特征,从道德教育接受心理机制出发,才能提高大学生道德教育的接受效果。

鲁迅与清末谴责小说

鲁迅在《中国小说史略》中通过历史考证和文本分析,对清末谴责小说的思想内容和艺术价值进行了总体评价。观点是切中肯綮的,但对这些特点的形成原因论述尚不够充分。同时,鲁迅还对清末谴责小说中部分作品所体现出的特异性加以观照,在文学创作中用杂文和小说的形式诠释了文学史写作中的某些观点,锋芒直指社会现象,宣判了旧有制度解体的同时完成了对清末谴责小说的超越。

钢壳沉管端钢壳三维姿态验收测量技术

在钢壳沉管隧道施工中,钢壳管节浇筑前后的验收主要是对端钢壳进行三维姿态测量,主要包括端钢壳面板(端面板)平整度、端钢壳横向垂直度(水平偏角)和竖向倾斜度(竖向偏角),目的是保证沉管精确地沉放安装。根据深中通道沉管隧道端钢壳施工验评标准,要求端钢壳总体测量精度达到mm级,难度较大。为满足测量精度,采用了一种钢壳沉管三维姿态测量技术,主要是利用高精度全站仪+全圆法观测软件+MATLAB数学软件对钢壳沉管端钢壳三维姿态进行测量并处理分析各项数据指标,评定端钢壳在钢壳管节浇筑前后的精度,同时能确保工序之间合理衔接。

NOVEL SPLICING MUTATION OF COL1A1 GENE CAUSING OSTEOGENESIS IMPERFECTA TYPE I IN CHINESE PEDIGREE

Objective To detect the peculiar mutation in a Chinese family with osteogenesis imperfecta,COL1A1 and COL1A2 being analysed. Methods A genome screen was undertaken covering COL1A1 at 17q21-22 and COL1A2 at 7q22.1. The Linkage ( Version 5.1 ) was used for 2-point analysis. DNA sequencing was used to screen and identify the mutation. Results A linkage to the markers on chromosome 17q21-22 was observed. Sequence analysis of COL1A1 revealed a splicing mutation ( IVS8-2A ＞ G) that converted the 3' end of intron 8 from AG to GG. Conclusion This mutation ( IVS 8-2A ＞ G) is novel, and has not yet been registered in the Human Type Ⅰ and Type Ⅲ Collagen Mutations Database.     

DIFFERENTIAL EXPRESSION OF GENES IN OMENTAL FAT OF NORMAL WEIGHT AND OBESE SUBJECTS AND OBESE DIABETIC PATIENTS USING cDNA MICROARRAY

Objective To identify genes differentially expressed in omental fat of normal weight subjects,obese subjects and obese diabetic patients. Methods Using a high-density cDNA microarray, gene expression profile of omental fat from normal weigh subjects, obese subjects and obese diabetic patients were compared.Results Totally, 119 and 257 genes were up-regulated in obese subjects and obese diabetic patients respectively,while 46 and 58 genes were down-regulated. A total of 77 genes, including PDK4, which switched from carbohydrate to fatty acids as the primary source of fuel, were up-regulated in both obese and obese diabetic patients, while 8 genes, including key enzymes in lipid synthesis, such as HMG-CoA synthase, fatty acid synthase and stearoyl-CoA desaturase, were down-regulated in both groups. Tyrosine-3-monooxygenase/tryptophan 5-monooxygenase activation protein θ ( YWHAZ) , a negative regulator for insulin signal transduction, was up-regulated only in obese diabetic patient, but not in normal-glycemic obese subjects. Conclusion The study demonstrated that decrease of lipogenesis along with increase of fatty acids oxidation of adipose tissue could be a common cause of insulin resistance in obesity and type 2 diabetes, while block of insulin signal transduction may trigger the transition from obesity to diabetes. Further exploration of these genes will be useful in the understanding of the pathogenesis of obesity and diabetes.
