探讨人民币汇率制度的发展方向     

魏星 《徐州师范大学学报(哲学社会科学版)》2002,28(3):34-37

经济全球化和金融自由化推动了金融全球化的迅速发展。金融环境的变车呼唤着我国僵化的人民币汇率由有管理的浮动制度向真正的管理浮动制度转变。尤其进入新世纪，我国在经历了经济制度改革、创新后，经济日新月异，无论从GDP的年增长速度、国际收支状况，还是从金融市场的发展角度看，都具备了汇率制度改进的条件。在充分利用这一改革契机的同时，我们应该意识到经济、金融环境稳定对于一国改革、发展的重要性，认识到改革方式会直接制约改革成铲，所以汇率制度的发展应坚持循序渐进的原则，不宜完全浮动化,而适宜采取汇率目标区的形式，并注重加强亚洲地区的金融合作，增强汇率制度的稳定性。  相似文献   

我国艺术立法原则和研究要点思考     

李阳生  谭魏 《湖南科技学院学报》2006,27(3):288-289

艺术法不是一部单行法规，而是相关法规的总称。由于艺术的外延很大，其所涉及的社会关系也是多种多样，而不仅仅是有关版权的问题，因此，有必要从宏观上把握艺术发生过程中所涉及的一些重要关系。  相似文献   

中欧贸易磨擦的冲击及企业的改型——构建学习型企业的几点思考     

高松 《通化师范学院学报》2007,28(6):36-38

中国入世五年来,中欧贸易取得了举世瞩目的成果,然而,中欧贸易摩擦也随着贸易额的增长不断升级;中国政府将采取有选择的鼓励进口和适当限制出口等措施改善对外贸易环境,这必将对国内企业带来巨大冲击和新的挑战,而构建学习型企业,是企业保护自己,应对国外反倾销调查和在实现国际收支平衡过程中迎接挑战的必然选择。  相似文献   

试析入世过渡期结束后国有专业外贸公司的发展问题   总被引：3，自引：0，他引：3  

许华兰  马野青 《金陵科技学院学报(社会科学版)》2005,19(2):30-33,41

我国入世过渡期结束、外贸经营权放开以后，以前为国有专业外贸公司提供货源的厂家获得外贸出口权，国有专业外贸公司面临失去货源和客户的风险。为此，90年代后半期以后不少专业外贸公司纷纷向实业化转型。该文根据有关经济学理论对此问题进行了探讨，并对今后国有专业外贸公司的发展问题提出了自己的建议。  相似文献   

The influence of heterogeneous exposure and pre-deliberation queries on pretrial publicity effects     

Jon Bruschke  Andrew Gonis III  Sarah A. Hill  Pam Fiber-Ostrow  William Loges 《Communication monographs》2016,83(4):521-534

Prior research on pretrial publicity has produced mixed results and a roughly equal number of studies show an effect, show no effect, or show mixed results. We explored the effects of (a) homogenous vs. heterogeneous exposure (whether deliberating jurors were all exposed to the same publicity or not) and (b) pre-deliberation queries as potential contributors to mixed results. We found an effect for positive but not negative publicity on conviction rates but not evidence ratings. Exposure heterogeneity appears to explain these differences and pre-deliberation queries did appear to play some role in the obtained outcomes. Overall these findings do not replicate a robust publicity effect and future research should consider how homogeneous exposure and pre-deliberation opinion queries influence results.  相似文献   

WTO教育服务贸易的主要规则解析   总被引：10，自引：0，他引：10  

邬志辉 《外国教育研究》2003,30(3):29-34

WTO的精髓是规则，WTO规则的特点是“原则＋例外”。中国教育若想在世界教育服务竞争中占有一席之地，就必须学会在规则的缝隙当中去生存，学会运用规则来保护自己、发展自己。文章从GATS文本解读入手，阐释了教育服务、教育服务贸易、教育服务贸易壁垒的含义与范围，论述了非歧视与公平竞争、稳定性与可预见性、发展性与差别对待三大基本原则和例外规定，分析了世界对教育服务贸易的态度和我们的立场。  相似文献   

Neuromuscular and technical abilities related to age in water-polo players     

Fabio De Siati  Guillaume Laffaye  Giorgio Gatta  Antonio Dello Iacono  Johnny Padulo 《Journal of sports sciences》2016,34(15):1466-1472

Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s^?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses.  相似文献   

A topography of free kicks in soccer     

Daniel Link  Otto Kolbinger  Hendrik Weber  Michael Stöckl 《Journal of sports sciences》2016,34(24):2312-2320

ABSTRACT

This study investigates the spatial relationship of performance variables for soccer free kicks. In order to suggest ways in which players might optimise their performance, we collected data from free kicks (<35 m to goal line) of two German Bundesliga seasons (2013/14, 2014/15) (n = 1624). In the analysis, we applied the ISO-map approach using colour gradients to visualise the mean values of a variable on a 2D-map of the pitch. Additionally, variograms were used to describe the degree of spatial dependence of the free kick variables. Results show that DENSITY, TYPE OF PLAY, PLAYERS IN WALL, DISTANCE TO WALL and RULE VIOLATION were strongly spatially dependent. Centrality and proximity to the goal increased the variables PLAYERS IN WALL, RULE VIOLATIONS and INTERRUPTION TIME, and the ratio of goals scored increased from 5.9% (central far) to 10.9% (central near). In 70.9% of the shots, players preferred a switched laterality, which did not result in a higher success rate. Furthermore, there was no statistical advantage for the defensive team when DISTANCE TO WALL was below 9.15 m or when there was a RULE VIOLATION. Crosses had a success rate (i.e., first controlled ball contact after the cross) of 20.8%. Played with natural laterality, they were 5% more successful than with switched laterality. Crosses from the right side outside the penalty box were 10% more successful than from the left side. Therefore, it might be worthwhile practising the defence of balls coming from this side.  相似文献
