当代国际贸易中非关税壁垒的新体系及其作用机理

随着世界贸易组织对关税和传统非关税壁垒的约束,非关税壁垒形成以技术壁垒为核心的,包括技术壁垒、环境壁垒、社会壁垒和道德壁垒在内的新体系,成为当代国际贸易的新贸易壁垒.相对于传统贸易壁垒,新型非关税壁垒表现出合理与保护的二重性、保护方式的隐蔽性和实施标准、法规和程序的复杂性,从壁垒的实施过程来看,新型非关税壁垒具有数量控制和价格控制的双重限制作用.     

中国民航法律规制的发展与完善

近年来,中国民航取得了突飞猛进的发展,航空运输规模已连续14年稳居世界第二位。民航的快速发展离不开完善的法律保障。目前,我国已经形成以《民航法》为核心的民航法律体系,但民航法律体系仍存在法律制度不健全、民航市场监管制度与纠纷解决机制不健全等问题。本文从民航法律规制的整体性出发,分析了我国民航法律规制的不足,借鉴美国和欧盟等国外民航法律规制的先进经验,提出了完善我国民航法律规制的相关建议。     

互联网+“国际双师教学”:促进高等教育国际化发展的新途径

随着中国建设世界一流大学和一流学科的“双一流”水平的不断提高,国际化已经成为中国高等教育的发展战略之一。实现高等教育的国际化,必然需要具有先进的国际教育理念、共享优质的国际教育资源、引进先进的国际课程和高水平的外籍师资。在对中国国内互联网+“双师教学”进行追溯和分析的基础上,提出了互联网+“国际双师教学”这一新的教育模式,旨在期待其可以成为有效促进中国高等教育国际化发展的新途径。     

Macro-conditions and immigrants' happiness: Is moving to a wealthy country all that matters?

Migrants look for a better life. In what kind of country will they live happiest? Many migrants aspire to move to wealthy countries, but non-economic factors might be important as well in making a country livable for migrants. This issue is addressed here by examining the impact of macroeconomic conditions and non-economic macro-conditions (good governance and a pleasant social climate) on immigrants' happiness in twenty European nations. We find that immigrants' happiness depends both on economic and non-economic macro-conditions. The social climate is especially important, particularly in terms of a positive attitude in society towards migrants. Our findings imply that the choice of destination country matters for migrants’ happiness and that the discrepancy between migration motives and migration outcomes may constrain immigrants from maximizing subjective gains via migration.     

Order statistics from trivariate normal and -distributions in terms of generalized skew-normal and skew- distributions

We consider here a generalization of the skew-normal distribution, GSN(λ₁,λ₂,ρ), defined through a standard bivariate normal distribution with correlation ρ, which is a special case of the unified multivariate skew-normal distribution studied recently by Arellano-Valle and Azzalini [2006. On the unification of families of skew-normal distributions. Scand. J. Statist. 33, 561–574]. We then present some simple and useful properties of this distribution and also derive its moment generating function in an explicit form. Next, we show that distributions of order statistics from the trivariate normal distribution are mixtures of these generalized skew-normal distributions; thence, using the established properties of the generalized skew-normal distribution, we derive the moment generating functions of order statistics, and also present expressions for means and variances of these order statistics.Next, we introduce a generalized skew-t_ν distribution, which is a special case of the unified multivariate skew-elliptical distribution presented by Arellano-Valle and Azzalini [2006. On the unification of families of skew-normal distributions. Scand. J. Statist. 33, 561–574] and is in fact a three-parameter generalization of Azzalini and Capitanio's [2003. Distributions generated by perturbation of symmetry with emphasis on a multivariate skew t distribution. J. Roy. Statist. Soc. Ser. B 65, 367–389] univariate skew-t_ν form. We then use the relationship between the generalized skew-normal and skew-t_ν distributions to discuss some properties of generalized skew-t_ν as well as distributions of order statistics from bivariate and trivariate t_ν distributions. We show that these distributions of order statistics are indeed mixtures of generalized skew-t_ν distributions, and then use this property to derive explicit expressions for means and variances of these order statistics.

联合国改革努力的历史发展

联合国改革长期以来是国际社会关注的焦点,为了理解这一进程的未来走向,有必要清醒地认识它所经历的历史发展.联合国改革涉及组织结构、管理程序以及宪制安排三个方面,涵盖国际安全以及经济和社会问题两个主要领域,反映出各国在这些问题上的不同立场和观点.联合国改革努力的不同规划表明,在这些领域取得实质性突破仍然困难重重.     

对完善我国外国法查明制度的探讨

在当代国际社会,一国能否正确把握国际私法中外国法内容的查明制度,已经成为该国法院能否保障司法程序公正和促进国际民商事关系协调发展的重要基础.然而,我国对外国法的性质、外国法查明的责任主体、各责任主体同责任的划分、外国法查明的途径、外国法无法查明的认定以及外国法无法查明时的处理方法等问题的规定在立法、理论和实践上尚存在一些问题.借鉴国外的有益经验,对上述问题进行深入探讨,将有益于促进我国外国法查明制度的完善和国际民商事关系的协调发展.     

Does Society Matter? Life Satisfaction in the Enlarged Europe

Life satisfaction is quite heterogeneously distributed across countries of the enlarged European Union. Previous research has shown how living conditions within individual countries, such as access to material and emotional resources, are important for personal well-being, but it has been less successful in explaining differences between countries. This article investigates whether it matters in which political and economic circumstances people live, as well as whether their particular perception of the quality of their societal environment plays a role. People are well aware that the institutional and cultural settings in which their lives are embedded create opportunities and limitations: within individual countries, perceptions of society influence life satisfaction outcomes irrespective of access to resources. However, their importance for well-being differs across Europe: perceptions of societies are highly decisive in countries that provide only a minimum of social security and in which the reliability of political institutions is poor. In rich and stable countries, the impact is weaker and private social support becomes more important. In addition to these country-specific weights of life satisfaction determinants, life satisfaction variations between countries can be explained to a large extent by taking into consideration the economic performance, the social security level, and the political culture in a country—all in all, general conditions that enable people to live a respectable life.
