我国现阶段毒品犯罪原因分析

提出改革开放之初防毒机制的弱化 ,部分地区经济极度贫困 ,现实庞大“消费市场”的刺激是我国毒品犯罪发展蔓延的主要国内因素 ,国际毒品犯罪的日趋猖獗及毒品犯罪分子对巨额利润的贪婪追求也是我国现阶段的毒品犯罪发展的重要原因     

激情燃烧的艺术--林建勋书法印象

林建勋的书法倾注了艺术的真诚,其代表作<孙子兵法竹刻长卷>耗费时间最长、投入精力最多.林建勋的书法既富于刺激性,又不乏耐看性在字体选择上,他嗜狂草;在幅式选择上,他多取鸿篇巨制;在风格塑造上,他重气势的表现;在创作上,他纵心而不逾规矩;在形式上,他寓多样于统一之中;在格调上,其作品狂而不怪,犷而不野.

CIDE gene expression in adipose tissue,liver, and skeletal muscle from obese and lean pigs

The expression of the cell death-inducing DNA fragmentation factor α-like effector (CIDE) family including Cidea, Cideb, and Cidec was significantly increased in mouse and human models of obesity. However, there was less information on these genes’ expression in pigs. Here, we hypothesized that different fat accumulation between lean (Duroc×Landrace×Yorkshire gilts, DLY) and obese (Lantang) pigs was attributed to porcine CIDE-modulating lipid metabolism. Our data showed that Cidea and Cidec were expressed at a high level in adipose tissue, and at a relatively high level in skeletal muscle, whereas Cideb was mainly expressed in the liver in both breeds of pig. Lantang pigs had higher white adipose and skeletal muscle Cidea and Cidec mRNA abundance, and hepatic and muscle Cideb mRNA than DLY pigs. Lipid metabolism-related genes including sterol regulatory element binding protein 1c (SREBP-1c), hepatocyte nuclear factor-4α (HNF-4α), peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), fatty acid synthase (FASN), diacylglycerol O-acyltransferase 1 (DGAT1), and DGAT2 showed a higher expression level in adipose tissue from obese pigs than in that from lean pigs. Lantang pigs exhibited higher mRNA abundance for liver SREBP-1c, HNF-4α, and PGC-1α, and higher skeletal muscle SREBP-1c, HNF-4α, PGC-1α, and DGAT2 expression, as compared with DLY pigs. However, the perlipin2 mRNA levels in adipose tissues, liver, and skeletal muscle were significantly lower in obese pigs than in their lean counterparts. Furthermore, plasma non-esterified fatty acid (NEFA), glucose, and triacylglycerol (TAG) levels were greater in obese pigs than in lean pigs. Finally, data from correlation analysis further found that CIDE mRNA expression was positively correlated with back fat thickness (BFT), abdominal fat mass (AFM), and the levels of NEFA, TAG, and glucose in the two breeds. Collectively, these data revealed that the porcine CIDEs possibly modulated lipid metabolism and contributed to the development of fat deposition and obesity in Lantang pigs.

大学诊断的理念与实践

大学诊断是国外最近兴起的针对大学开展评价和咨询服务的一种新的形式,它类似于企业诊断。大学诊断是在多种指标数据和调查研究的基础上,采用各种计量方法、定性分析和比较方法对大学的现状、水平和前景竞争力等各个方面进行全面系统地分析,提出判断性的评价意见和发展对策。以武汉大学社会科学研究竞争力评价为例,在中国高校人文社会科学研究竞争力评价的指标数据和评价结果的基础上,通过同类高校之间的比较分析,揭示武汉大学社会科学研究的优势与差距,提出有针对性的发展对策和建议。

东西方跨文化交际中的非语言屏障

面对跨文化交际中的种种障碍,人们普遍认为语言是产生这道屏障的主要根源;然而,从根本上讲,东西方跨文化交际的鸿沟往往来源于一些非语言因素。因此,文章将以非语言因素为切入点,层层深入地分析非语言因素对东西方跨文化交际造成的障碍,从而有利于参与交际的双方跨越文化的屏障,与来自异质文化环境的人们自如地沟通。
