广东对外贸易与经济增长关系的协整分析

利用多种计量分析工具,从总量和增长效应的角度研究了广东进出口与GDP增长间的关系。研究发现:从长期来说,进口、出口与GDP存在唯一稳定关系,出口较进口对经济增长有更大的促进作用;从短期来说,进口增长、出口增长都是GDP增长的Granger原因,出口增长同时也是进口增长的Granger原因,进口增长、出口增长都带动了经济增长,而且进口增长比出口增长与经济增长有更稳定、更紧密的联系

Trade, education, and innovation: Prospects for the U.S. economy

This paper examines international trade issues as vital indicators of the economic prospects of the United States and other developed economies. In particular, it challenges misuses of the doctrine of mutual gains from trade and instead argues that comparative advantage does not guarantee increases in benefits to both trading partners—especially when one partner seeks to distort the market mechanism in its favor. In the face of such mercantilist or protectionist practices, efforts to advance innovation, without retaining manufacturing jobs, will not ensure continued prosperity, as the number of jobs entailed in the invention process is small compared with the number of jobs associated with manufacturing an innovative product for mass consumption. These matters call for the urgent rethinking of trade policy by the United States and other developed nations, if they are to balance their imports and exports and ensure continued economic growth.     

Texting among United States young adults: An exploratory study on texting and its use within families

The current study examines general text messaging tendencies, patterns of and reasons for texting family members, and the impact of texting on familial relationships among a young U.S. adult sample. Participants were recruited through Facebook; they then completed an online questionnaire. Data from 127 young adults (men: 38; women: 87; unidentified: 2) are analyzed and compared by gender. Findings suggest that young adults text at high rates per month. Participants generally report a prompt response to texts and their ability to honestly express feelings within these messages. Results also suggest participants text family members for a variety of reasons, such as to convey information, plan activities, and engage in general conversation. Distinct gender differences, however, are evident regarding who men and women text as well as texting's effects on familial relationships. Overall, these findings expand researchers’ understanding of texting in general and its impact within the family.     

A Feminist Policy Analysis Framework

ABSTRACT

Most policy analysis models, both inside and outside of social work, approach policy in a gender-neutral manner. This fact belies the many ways our society is organized around gender, which is often regulated through policy. This article outlines a model for looking at policies through a gendered lens by framing a set of questions to be asked in a feminist policy analysis. The complexities and underlying issues inherent in such a model are discussed, as well as the model's implicit goals and values. The model provides an important framework for policy analysts and teaching students about policy.     

中国加入世贸组织关税谈判的政治经济分析

An evaluation of product commonality and group technology production methods in a pre-defined multiple-machine scenario

Group technology has been used successfully for a number of years as a setup reduction tool. It is especially valuable in low-volume high-mix manufacturing environments where products and machines may be partitioned into product families and machine cells. The partitioning of machines or processes into cells may be limited by practical constraints, and the partitioning of products is complicated as the number of products and processes increases. In this paper, the authors examine the behaviour of various grouping strategies lauded as being appropriate in situations where machine partitioning and product routeing are determined by technological constraints. Of specific experimental concern in this paper is the effect of the mean and variance of component part commonality between products on system performance under various grouping strategies in a multiple-machine environment.     

Manufacturing management strategies for environmental protection: Toward the environmental upgrading of management and manufacturing systems to cope with environmental laws

Recent environmental problems have been caused by business activities and a lifestyle based on mass production, mass consumption and mass disposal. These problems have also become global in scale. Increasingly, global efforts are being applied to preserve and improve the environment. NEC, a worldwide electronics manufacturer, created its own environment action plan called Eco-Action 21. This is a continuously evolving plan applied throughout the NEC group and subsidiaries. Globally, 34 NEC manufacturing sites have received ISO 14001 certification. NEC Tohoku in Japan and NEC Ireland obtained BS 7750 certification even before this. NEC improves subcontractors' environmental behaviour with our accumulated expertize and technology derived from our ISO experience and our own development. Input for this paper was not only from NEC Tohoku and the NEC group, but also from outside NEC.
