西方贸易与环境理论的演化及新发展

20世纪70年代以来,贸易与环境问题就开始成为国际关注的问题,贸易自由主义者和环境保护主义者就此从未停止过争论。文章主要对其争论的主要领域进行了总结,对自由贸易和环境保护之间的关系进行了评述,希望能对我国更好地开展自由贸易提供一些借鉴。     

声律:汉语言文学的听觉美感

中国人对汉语音调之美的把握经历了一个从模糊朦胧到自觉清晰的过程。六朝时期 ,“四声”的发现及其在创作中的尝试应用 ,诞生了声律论 ,标志着这一过程的完成。声律论强调五言诗的创作要凸显语言声调的规律变化。从深层意义上讲 ,这一理论暗合了中华民族崇尚和谐的美学精神

Working Unusual Hours and Its Relationship to Job Satisfaction: A Study of European Maritime Pilots

Our study focuses on maritime pilotage in seven European countries and analyzes the level of job satisfaction and its predictors. Like most existing studies in the field of job satisfaction, we show that job satisfaction is an outcome of the work of maritime pilots. Stressful working conditions, such as working unsocial hours and irregular working patterns, create strains that together with intervening factors related to work, family, or the work environment ultimately reduce job satisfaction. However, our results indicate that although negative physical and social consequences are important, they are neither the strongest nor the only variables determining job satisfaction. Another effect seems more important in European maritime pilotage: Job satisfaction is instead a predictor of how much pressure and stress pilots can handle. Despite health problems and a reduction in their quality of life due to working unusual hours, most maritime pilots do not regret their choice of profession. Factors to ameliorate the working conditions are also identified. The most important parameters include alterations in working time systems, working conditions which minimize physical strain, fairness regarding payment, flexibility within the compensation system, an intensification of the possibilities for involvement and participation, an extended degree of co-determination, and the distribution of the ownership of the pilot stations.     

早期酋长制群体的聚落形态比较研究——以内蒙古东部、安第斯山北部和美洲中部三个地区为例

对内蒙古东部、安第斯山北部和美洲中部三个地区的早期酋长制群体的聚落形态进 行的比较研究表明,尽管这三个地区的发展过程大致相当,但在这三个地区中,大体类似的转变 却以不同的方式发生,从而导致了三个各具特色的等级社会的出现。最初的、大规模的、以等级 制度原则组织起来的酋长制群体出现后,其发展轨道的早期阶段明显地为后来的、较大的、更复 杂的政治实体即国家的出现创造了条件。通过地域性聚落分析,可以发现这三个地区在不同规模 层次上的人口和社会组织的异同,其中在赤峰和奥哈卡(Oaxaca)地区都存在的小型群体却不见 于马格达雷那高地(AltoMagdalena)的现象,需要进行更深入的研究,才能进一步揭示出在马 格达雷那高地是什么样的社会交流把这些家庭联合成更大的社会团体。     

论民族聚落的形成及其民俗功能——以丝绸之路沿线民族情况为依据

民族聚落的形成,与民族群体中的人伦血缘宗族凝聚、地缘机制分布以及经济文化的板块结构等因素相关联。在社会发展的不同阶段,三者分别起着重要的主导作用。民族聚落在其形成后,发挥着稳定社会生活模式的民俗功能。     

香港高等教育社会适应性办学模式的质量问题及其启示

香港高等教育进入普及教育阶段后,学校的发展采用社会适应性办学模式,其模式在处理数量与质量上有顾此失彼,转型初期出现了诸如生源、师资、素质教育等质量问题。在实施社会适应性办学模式过程中(尤其九七年香港回归后),政府各界与学校一道推进了改革,从教育目标、课程建设、合作交流等方向可窥视他们的大胆尝试。     

The assessment of tumour response to treatment

Summary.  A parsimonious model for treated tumours is developed as a continuation of our previous work on regrowth curve theory. The statistical model belongs to the family of marginal non-linear models since the only linear parameters of the model are tumour specific and random facilitating parameter estimation. An important feature of the model is that it enables the estimation of the fraction of cancer cells surviving the treatment in vivo having easy-to-obtain longitudinal measurements of tumour volume. We compare several methods of estimation, including Lindstrom–Bates, iterated reweighted least squares and maximum likelihood. The last two methods are computed via the total estimating equations approach and variance least squares. The theory is illustrated with a photodynamic tumour therapy example.     

Acceptance sampling based on truncated life tests for generalized Rayleigh distribution

This paper considers the problem of an acceptance sampling plan for a truncated life test when the lifetime follows the generalized Rayleigh distribution. For different acceptance numbers, confidence levels, and values of the ratio of the fixed experiment time to the specified mean life, the minimum sample sizes necessary to ensure the specified mean life are found. The operating characteristic values of the sampling plans and producer's risk are discussed. Some tables are presented and the use of the tables is illustrated by a numerical example.     

Objective Testing Procedures in Linear Models: Calibration of the p-values

Abstract.  An optimal Bayesian decision procedure for testing hypothesis in normal linear models based on intrinsic model posterior probabilities is considered. It is proven that these posterior probabilities are simple functions of the classical F -statistic, thus the evaluation of the procedure can be carried out analytically through the frequentist analysis of the posterior probability of the null. An asymptotic analysis proves that, under mild conditions on the design matrix, the procedure is consistent. For any testing hypothesis it is also seen that there is a one-to-one mapping – which we call calibration curve – between the posterior probability of the null hypothesis and the classical bi p -value. This curve adds substantial knowledge about the possible discrepancies between the Bayesian and the p -value measures of evidence for testing hypothesis. It permits a better understanding of the serious difficulties that are encountered in linear models for interpreting the p -values. A specific illustration of the variable selection problem is given.
