从工业革命带来的社会变化中审视英国1832年议会改革的原因     

杨帆 《巢湖学院学报》2007,9(5):108-112

光荣革命后的很长时期里,土地贵族和金融寡头通过控制议会而掌握国家政权;到十九世纪初,随着工业化的推进,资产阶级财富增多,中等阶级和工人阶级力量壮大,参政意识觉醒,他们要求改革贵族寡头把持国家政权的旧制,分享权力。1832年议会改革就是在这样的背景之下产生的,工业革命所带来的经济和社会的变化对旧制度的反叛是改革的根本原因。面对澎湃兴起的改革浪潮,统治集团的审时夺势和适时退让是改革法案最终生效的关键。  相似文献   

探索与求解:“三个代表”重要思想与反腐倡廉     

范东翠  范志轩 《阿坝师范高等专科学校学报》2003,(3):10-14

中国共产党走过了八十多年光辉战斗历程,面对新世纪新阶段、新任务,必须按照“三个代表”重要思想的要求,全面推进党的建设新的伟大工程,必须坚持不懈地开展反腐败斗争,加强党风廉政建设,构建强有力的权力制衡机制,从体制上铲除腐败。只有这样才能增强党的凝聚力、战斗力、创造力,实现中华民族的伟大复兴。  相似文献   

安徽省与周边省份资本分布情况比较研究     

潘庄晨  范宸瀚  潘淑娟 《黄山学院学报》2007,9(6):90-93

将安徽、山东、江苏、江西四省并列,对90年代以来影响各省资本分布的各个因素:区域经济增长差异、财政转移支付差异、信贷投放差异、外商直接投资利用差异进行了深入分析并对四者所反映出来的情况与问题做了系统研究,从而发现从中央财政支付转移的角度看,山东、江苏二省每年都有相当数额的财政收入上缴中央政府,而安徽、江西二省2000年以来每年都接受大量的中央政府财政补贴,并有逐年增大的趋势.从银行及其资本渠道来看,四省均出现资本外流现象.  相似文献   

不同基因型大豆对硼敏感性的差异   总被引：2，自引：2，他引：2  

严红  张兴文  张喜林  宋时奎  王帆  戴先锋  曹东  彭伟  王冶  吴忠海  黄波 《大连大学学报》2004,25(6):38-42

本文采用田间试验方法研究三种基因型大豆北9395、北454和北384对硼敏感性的差异,结果表明,应试的三个大豆基因型在三个硼处理水平中,其单株粒重均随着硼处理浓度的增加而增加,硼促进籽粒干物质的积累;三个大豆基因型对硼的敏感性存在差异,北9395对低硼最敏感,且高硼时易出现中毒症状;北454需硼范围较宽;北384对低硼不敏感;北454和北384高硼时增产明显.  相似文献   

从《诗经》看周人的宗教哲学观     

樊国萍 《毕节学院学报》2003,21(1):81-84

集周代社会诗歌文大成的《诗经》 ,既是我国古代的一部光辉文学著作又是周代社会的一部百科全书。然而前人多从文学的角度去研究其价值 ,而很少涉及到它所反映的其他社会内容 ,例如周人的宗教哲学观等。从《诗经》的大量篇章中 ,论证周人宗教哲学观在《诗经》的表现并进而分析周人之宗教哲学与殷人宗教哲学的相承相因相革的关系 ,从而论述周人宗教哲学反映于《诗经》的内容 ,是周人对殷人宗教哲学的继承和发展。  相似文献   

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

Yue-qin Qiu  Xue-fen Yang  Xian-yong Ma  Yun-xia Xiong  Zhi-mei Tian  Qiu-li Fan  Li Wang  Zong-yong Jiang 《Journal of Zhejiang University. Science. B》2017,18(6):492-500

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.  相似文献

A novel multi-objective optimization method for the pressurized reservoir in hydraulic robotics     

Xiao-ping Ouyang  Bo-qian Fan  Hua-yong Yang  Shuo Ding 《浙江大学学报(A卷英文版)》2016,17(6):454-467

The pressurized reservoir is a closed hydraulic tank which plays a significant role in enhancing the capabilities of hydraulic driven robotics. The spring pressurized reservoir adopted in this paper requires comprehensive performance, such as weight, size, fluid volume, and pressure, which is hard to balance. A novel interactive multi-objective optimization approach, the feasible space tightening method, is proposed, which is efficient in solving complicated engineering design problems where multiple objectives are determined by multiple design variables. This method provides sufficient information to the designer by visualizing the performance trends within the feasible space as well as its relationship with the design variables. A step towards the final solution could be made by raising the threshold on performance indicators interactively, so that the feasible space is reduced and the remaining solutions are more preferred by the designer. With the help of this new method, the preferred solution of a spring pressurized reservoir is found. Practicability and efficiency are demonstrated in the optimal design process, where the solution is determined within four rounds of interaction between the designer and the optimization program. Tests on the designed prototype show good results.  相似文献
