The observation has frequently been made that uncertainty about the legal meaning and the economic and political effects of WTO agreements exert a discouraging effect on the progress of multilateral trade negotiations. This article identifies the determinants of uncertainty and risk in the WTO. It also examines changes in these determinants over time, pointing to increasing levels of uncertainty and risk. The argument is based on a series of interviews conducted with members of national delegations to the WTO and with WTO employees. 相似文献

This article addresses the impact of productivity, corruption, and trade openness on the stock returns of 265 industrial companies listed in eight Eastern European fast-emerging markets, over the 2004-2013 period. Through a three-factor model that includes both measures at firm level and macro-level control variables, our findings suggest that country corruption index is negatively correlated with the total annual return of the stocks of the listed industrial companies of our sample. Moreover, the most productive firms are featured by higher stock returns, while leverage seems not to be a key predictor of stock returns. In addition, the article uncovers innovative evidence about trade openness that is negatively correlated with stock returns due to its connection with the recent financial crisis. That is, firms operating in markets that are more open to trade show a higher degree of interconnection with other economies and are more likely to undergo the effects of negative fluctuations from foreign markets during the economic crisis. © 2015 Wiley Periodicals, Inc. 相似文献

This paper aims to offer a new Internet driven theoretical framework that explains how a successful internationalisation process may be developed and identifies the strategic dimensions that influence the key decisions in an interrelated, performance-associated way. The extant literature is examined in international marketing, international entrepreneurship and Internet marketing and a comprehensive strategic analysis is conducted of a successful individual services business: ING Direct. It is shown how strategic constructs and risk constructs drive the internationalisation process in an interrelated and performance-associated way. In the framework, the firm's target is to take advantage of an opportunity by obtaining a sustainable competitive advantage while attenuating international risk. Entry mode and country selection are strategic decisions interrelated mutually and with other strategic choices and with performance; this is why an analysis with ceteris paribus statements or episodic analysis may lead to the wrong conclusions. 相似文献

提出了一种用于扇束CT(计算机断层扫描)重建的快速滤波反投影算法.这种算法是传统标准滤波反投影(FBP)重建算法的加速形式,主要通过减少投影数量然后重建子图像来实现.实验结果表明:对于一幅512×512图像,这种算法可以将重建过程加速40倍以上,并且不会引入明显的图像误差.这种算法也适应于多层螺旋三维重建,并且可以延伸用于三维锥形重建. 相似文献

The food sector has taken on an unprecedented dynamism in recent years. The processing and distribution of food, although heavily influenced by tradition, have seen intensive innovations, leading to changes in the way individuals consume. One of these changes is the consistent growth of the habit of eating outside the home. Consuming food outside the home involves a number of practices such as eating at commercial establishments that specialize in food (restaurants, fast food restaurants and snack bars) and those that offer food as a part of their services (hotels, in‐flight meals), and non‐commercial alternatives such as the homes of family and friends. In order to describe the eating habits of consumers in the town of Lavras in Minas Gerais State, Brazil, especially when it comes to eating outside the home, a quantitative study was conducted, with 413 questionnaires being distributed by convenience sampling. Among the main results are: (a) a search for variety as a motivator for eating outside the home; (b) convenience as an important element on many occasions of consumption; (c) more intensive consumption and more favourable attitudes towards eating out on the part of younger people, people with higher incomes, no children and a higher degree of schooling; (d) importance of paying for food by the kilo. When compared with a study conducted in England, important similarities were identified in socio‐demographic influences, although the cultural factors are notable when it comes to dishes and the types of eating establishment. The growing habit of eating out has therefore become a worldwide phenomenon, but with cultural and regional differences that have led to different rhythms in terms of change and the way food is supplied. The recovery of embedded cultural habits, with increased value being given to slow food, traditional dishes and tradition itself, appears to co‐exist with a productivity model of food courts, pasteurization and accessible prices. The occasion for consumption, which may be understood as the dichotomies of ‘weekday versus weekend’ or ‘convenience versus leisure’, is an important element that influences consumer behaviours. The undertaking of a cross‐cultural comparative study can be seen as an important step in this field of research. 相似文献

针对目前装饰工程陕速估价方法的不足,以及装饰工程造价组成的特点,建立一种基于多元线性回归的快速估价新模型。以住宅类建筑为例,建立其多元线性回归模型,结合SPSS软件对样本分析,结果表明,其线性回归模型显著,同时,内墙、外墙、楼地面和窗的回归系数也非常显著。通过计算回归值与实际值的误差,发现误差比较理想,该模型具有很好的实用价值。 相似文献
