美国对华贸易的政治经济学分析

美国对华贸易虽以保持稳定的经贸关系为基础，但迫于国际政治需要和国内的集团利益，还存在许多不确定性。因此，中国应当从宏观上对中美经贸关系拓展战略性思维，加强开展商务外交，构建和谐的国际经贸新秩序；从微观上，完善政府的商务职能，加强企业国际化能力，充分发挥行业协会的作用，多方面促使中美贸易朝正常化方向发展。     

Consumer trust in B2C e-Commerce and the importance of social presence: experiments in e-Products and e-Services

Reducing social uncertainty—understanding, predicting, and controlling the behavior of other people—is a central motivating force of human behavior. When rules and customs are not sufficient, people rely on trust and familiarity as primary mechanisms to reduce social uncertainty. The relative paucity of regulations and customs on the Internet makes consumer familiarity and trust especially important in the case of e-Commerce. Yet the lack of an interpersonal exchange and the one-time nature of the typical business transaction on the Internet make this kind of consumer trust unique, because trust relates to other people and is nourished through interactions with them.This study validates a four-dimensional scale of trust in the context of e-Products and revalidates it in the context of e-Services. The study then shows the influence of social presence on these dimensions of this trust, especially benevolence, and its ultimate contribution to online purchase intentions.

How to keep Rosie the riveter from contracting VD: A case study of how U.S. social reformers used public relations during World War II

Much of public relations historiography on World War II focuses on the government uses of the function. This study fills a gap in the literature by exploring how a non-governmental organization called the American Social Hygiene Association (ASHA) used persuasion communication efforts to enlist the aid of management, labor, and local communities in the United States in the control of venereal disease (VD) rates. The case study advances a more diverse understanding of how activists have utilized public relations and found that the social reformers’ use of persuasive communications strategies and activities aligned with the view of public relations as the strategic and intentional participation in the social construction of meaning to achieve a planned outcome.     

Business reform outcomes: Why so different?

Post-crisis policy making increasingly focuses on doing business reforms. We argue that the effects of those reforms will be different across countries. To understand the reasons for the reform outcome divergence, we advance a novel firm-size distribution (FSDs) argument. At the center of the argument is the fact that FSDs are different across countries and stable over time. Then, if a given doing business reform induces firms of different size to grow differently, this will produce a variety of reform outcomes across countries. To advance the argument, we set up a tractable general equilibrium (GE) model and study how firms of different size grow after a doing business reform. The model predicts that larger firms will grow faster than smaller firms after the reform. The model predictions are tested on the Enterprise Surveys (ES) data, merged with the Doing Business indicators. We confirm that firms of different size grow differently after a Doing Business reform. Thus, based on the notable differences of firm size distributions across countries, identical reforms to start, operate and close a business will produce a variety of reform outcomes across countries.     

当前阿拉伯革命态势分析

阿拉伯世界自2011年以来发生持续动荡，埃及、突尼斯、利比亚、叙利亚先后出现政局动荡甚至政局颠覆。当前阿拉伯世界的各种力量之间相互博弈，这将长期左右阿拉伯世界的政局。伊斯兰政治势力不断壮大，其极端思想及行为是阿拉伯世界政局动荡的重要影响力量，阿拉伯世界的青年人对政局不满，不断爆发大规模示威游行，处于边缘地位的工人阶级、世俗主义者与非政治民众对当前局势的态度也影响着阿拉伯地区的稳定。

An evaluation of donor agencies’ policies on participatory development: The case of Ghana

This article critically evaluates guidelines concerning participatory development by the World Bank and the United States Agency for International Development (USAID). It focuses on the different conceptual frameworks adopted in order to examine the different ways of incorporating participation in their development agenda. A literature‐based method was adopted and the analysis included evaluation of five documented experiences, including the Ghana Secondary Education Improvement Project and Ghana Water Sanitation and Hygiene Project from both the World Bank and USAID. Baum project cycle stages have been taken as activities for project participation. The findings show the need for better planning, ensuring sustainability and involving beneficiaries.
