国际人权公约与我国人权立法的比较   总被引:8,自引:0,他引:8  
本文通过国际人权公约和我国人权立法的比较,可以看到我国人权立法与世界共同标准不断接近的轨迹.尽管权利的确立和保障,要受一国经济、社会和文化发展水平的制约,采取的步骤应与一国的国情和承受能力相适应.但毫无疑问,继续缩小两者的差异,解决相互间的冲突,是我国人权立法完善和前进的方向.  相似文献

This article explores whether trade facilitation – i.e. improved and simplified trade procedures – could be an important part of the reform agenda of the Barcelona Process. Adopting a Southern perspective by focusing on exports to the European Union (EU) from non‐EU Mediterranean countries, it tests whether the efficiency of trade procedures affects (i) bilateral volumes of exports and (ii) the number of products exported. The findings suggest that trade facilitation could lead to substantially increased export volumes and export diversification.  相似文献

The authors examine how contributions to household resources, indicated by employment status, influence satisfaction with household income (SWHI) for members of male/female couples. They take changes in SWHI, which may differ within couples, to indicate changes in perceived benefits from their common household income, benefits that can go beyond individual consumption. Using data from the British Household Panel Survey for 2,396 couples from 1996 to 2007, three gender effects are identified. First, men predominate in making the type of contribution that most positively influences SWHI, namely, full‐time employment. Second, the effect of contributions depends on the gender of the contributor, with men's employment being more influential than women's. Third, within couples, making the more influential contribution, as men tend to do, leads to relatively greater SWHI. The authors conclude that gender asymmetry in contributions made to household resources is one way in which gender inequalities invade and inhabit households.  相似文献

A new class of statistical tests for uniformity based on sample ranges is proposed to detect a uniform density contaminated by a density with one or more high peaks. These kinds of alternatives occur quite frequently, especially in physics. It is shown that the proposed tests arc consistent and have high Pitman asymptotic relative efficiencies. Results of a Monte Carlo power study indicate that they, compared with other tests of uniformity, possess good power properties.A comparative study of various tests is also conducted using real data. An effcient algorithm for computing out test statistic and a table of percentage points are given, providing a practical guide for using the new test.  相似文献

We study a hypothesis testing problem involving the location model suggested by Olkin and Tate (1961). Specifically, we derive a likelihood ratio lest of the associated location hypothesis as an alternative to the conventional method of carrying out separate tests for each of the parameters. A small sample Monte Carlo comparison indicates the general superiority of the former in terms of statistical power. We also comment briefly on the properties of the test.  相似文献

We consider the issue of sampling from the posterior distribution of exponential random graph (ERG) models and other statistical models with intractable normalizing constants. Existing methods based on exact sampling are either infeasible or require very long computing time. We study a class of approximate Markov chain Monte Carlo (MCMC) sampling schemes that deal with this issue. We also develop a new Metropolis–Hastings kernel to sample sparse large networks from ERG models. We illustrate the proposed methods on several examples.  相似文献

A quantitative microbial risk assessment (QMRA) according to the Codex Alimentarius Principles is conducted to evaluate the risk of human salmonellosis through household consumption of fresh minced pork meat in Belgium. The quantitative exposure assessment is carried out by building a modular risk model, called the METZOON-model, which covers the pork production from farm to fork. In the METZOON-model, the food production pathway is split up in six consecutive modules: (1) primary production, (2) transport and lairage, (3) slaughterhouse, (4) postprocessing, (5) distribution and storage, and (6) preparation and consumption. All the modules are developed to resemble as closely as possible the Belgian situation, making use of the available national data. Several statistical refinements and improved modeling techniques are proposed. The model produces highly realistic results. The baseline predicted number of annual salmonellosis cases is 20,513 ( SD 9061.45). The risk is estimated higher for the susceptible population (estimate  4.713 × 10−5; SD 1.466 × 10−5  ) compared to the normal population  (estimate 7.704 × 10−6; SD 5.414 × 10−6)  and is mainly due to undercooking and to a smaller extent to cross-contamination in the kitchen via cook's hands.  相似文献

Age, time, and vintage are key determinants of house prices, yet they cannot be included together linearly or as dichotomous variables in hedonic regressions as construction time + age of house = sale time. We introduce a method where the estimates of the age, time, and vintage effects on prices are obtained in a flexible manner, without requiring us to specify a pre‐determined functional form for any of these variables. Applying our method to Dutch data, we find that the estimated depreciation pattern over the life of houses does not follow the functional forms typically specified for the age of houses in hedonic regressions.
