比较优势理论与对外贸易战略的选择

人们对比较优势理论的认识主要是为我所用的目的性所决定的。实际上,比较优势理论对现实的指导意义在于,把握好该理论运用实际过程的转折点。而对外贸易政策或战略的制定有两个不同层次的意义:一是国家宏观层面的;二是属于产业层面的,二者不能混淆。在不同的时期,贸易政策有历史的价值和局限性,有不同的部门适用性及自己特定的含义和适用性。因此,将国家宏观的对外贸易发展战略与对产业部门或产品在对外贸易发展中的战略性贸易政策区分开是非常重要的;比较优势理论的动态化是该理论的自有之意,而政府所能做的是推动和保障比较优势的充分发挥,并缩短从一种产业优势或产品优势向其他高附加值产业或产品优势转变的时间。     

Time-based goal chasing method for mixed-model assembly line problem with multiple work stations

In sequencing problems for mixed-model assembly line in JIT production system, the Goal Chasing method (GC) is widely used for parts used leveling goal. The difference in assembly time of each product is not taken into consideration in the Goal Chasing method. Assembly time usually varies with product types. In recent years, the Time-Based Goal Chasing method (TBGC) has been proposed. The advantage of TBGC is to consider the influence of different assembly time of each product and idle time in production period. TBGC, however, has been only applied to single work station problems. In this paper, TBGC is applied to an assembly line problem with multiple work stations. Furthermore, the sequencing method and use of Simulated Annealing (SA) or Local Search (LS) for this problem are proposed.     

Perceptions of efficacy in the use of contemporary film in social work education: An exploratory study

This article discusses the use of contemporary film in social work education, including the theoretical rationale for the inclusion of film from the perspective of narrative and adult learning theory as well as the application of the case method to the use of film. The student viewpoint and perspective is provided through the results of an exploratory research study with 109 Baccalaureate social work students who completed a survey questionnaire following a classroom activity involving a contemporary film. Analysis of the quantitative data and qualitative comments indicates that students believe that film is a beneficial adjunct to textbook and lecture content.

法律名著翻译借鉴——《牛津法律大辞典》译误评析

《牛津法律大辞典》是世界法律名著The Oxford Companion to Law的中译本,人们对此自然报有较高期望。然而,对照原文,发现该译本无论在总体把握还是具体表述方面错误和不妥之处颇多。本文主要从漏译、专业概念和专业表述等几个方面加以分析、评论,在指出纰漏的同时,探讨译文的改进。这与其说是对一部译作的评述,不如说是一项实用法律翻译研究。文中所举例子,尽管挂一漏万,但力求对提高这一领域的翻译质量有所借鉴和启示。     

比较教育研究方法与方法论之初探

方法与方法论是两个不同的基本范畴,研究方法关注数据的收集和数据的分析,而方法论则是注重研究的构思或理论框架,以及对研究结果的推广与交流。在比较教育领域,研究方法是进行比较教育研究的途径、手段及方式。方法论则是关于比较教育研究方法的理论,相当于对比较教育研究方式的探讨,即比较教育研究的基本原则或态度。比较教育方法论关系着研究方法的选择。科学方法体现了两者的统一。

A tolerance interval approach for assessment of agreement in method comparison studies with repeated measurements

This paper generalizes the tolerance interval approach for assessing agreement between two methods of continuous measurement for repeated measurement data—a common scenario in applications. The repeated measurements may be longitudinal or they may be replicates of the same underlying measurement. Our approach is to first model the data using a mixed model and then construct a relevant asymptotic tolerance interval (or band) for the distribution of appropriately defined differences. We present the methodology in the general context of a mixed model that can incorporate covariates, heteroscedasticity and serial correlation in the errors. Simulation for the no-covariate case shows good small-sample performance of the proposed methodology. For the longitudinal data, we also describe an extension for the case when the observed time profiles are modelled nonparametrically through penalized splines. Two real data applications are presented.
