INFORMATION INTERDEPENDENCE: Keohane and Nye's complex interdependence in the information age

A well-known and respected attempt to theorize interdependence in the field of international relations is complex interdependence. In Power and Interdependence , Robert O. Keohane and Joseph S. Nye, Jr define interdependence as reciprocal effects among actors resulting from 'international transactions - flows of money, goods, people and messages across international boundaries'. Though much research has been done on the effects of interdependence on the first three, the flows of messages have been studied less often. Keohane and Nye addressed the issue in a 1998 article in Foreign Affairs , discussing changes in the global environment resulting from the information age which have had an impact on their ideas. This article proposes to go deeper into complex interdependence. The world is becoming increasingly 'information interdependent' and this essay is an attempt to apply the assumptions and concepts presented in complex interdependence to the information age. In the final analysis, complex interdependence complements research from the field of communications, that information flows should be understood as underlying mechanisms and processes that facilitate contextual understanding of issues. It maintains the integrity of the assumptions of complex interdependence, while adding an understanding of the nature of information and information flows.

H2O2与UV／TiO2协同体系光催化降解酸性品红的研究

采用高压汞灯为光源，考察了H2O2与UV／TiO2协同体系对酸性品红的降解效果。结果表明：H2O2提高了UV／TiO2光催化降解酸性品红的速率。同时，研究了影响纳米TiO2光催化降解酸性品红的主要影响因素。实验结果表明：初始PH值等于7时，光催化效率最佳；随着初始浓度的增加光催化降解效率降低；TiO2的最佳用量为0．2g/L。     

FROM MAIZE TO HAZE: AGRICULTURAL SHOCKS AND THE GROWTH OF THE MEXICAN DRUG SECTOR

Understanding how economic incentives affect illegal drug production is essential for crafting policies in response to the international drug trade. Policymakers typically face a choice between two strategies: targeting criminal groups via law enforcement, and offering producers incentives to engage in alternate activities. Yet, little is known about how the returns to alternate legal activities affect drug supply. We contribute to this literature by examining how shocks to legal commodity prices affect the drug trade in Mexico. Our analysis exploits exogenous movements in the Mexican maize price stemming from weather conditions in US maize‐growing regions, as well as exports of other major maize producers. Using data on over 2200 municipios spanning 1990–2010, we show that lower prices differentially increased the cultivation of both marijuana and opium poppies in municipios more climatically suited to growing maize. We also find impacts on downstream drug‐trade outcomes, including drug cartel operations and killings perpetrated by these groups. Our findings demonstrate that maize price changes contributed to the burgeoning drug trade in Mexico, and point to the violent consequences of an expanding drug sector.     

O2O电子商务:动力、模式与前景分析

电子商务交易中消费人群必须上网、诚信体系不完善、线上推广成本日益提升、物流配送覆盖有限等问题,均导致电子商务无法对传统线下销售形成颠覆性改变。这就导致业界中出现了线上交易与线下交易的结合方式,即O2O电子商务。本文从对消费者价值、对电商企业的角度分析了O2O电子商务模式发展的动力所在,并根据O2O的特点总结出适合采用O2O模式的商品类型即服务型和体验型的产品。其次,本文总结了O2O商务发展的遭到创新、诚信和线上流量等瓶颈,接着分析了单纯线上和线下企业发展O2O电子商务面临的挑战和问题。最后展望了O2O模式未来的发展,即未来的O2O将是一种多层次、多维度的复合生态体系,不断向多元化和纵深化发展。     

生态社会主义的资本主义危机理论——基于詹姆斯·奥康纳《自然的理由》

詹姆斯·奥康纳以制度批判为视角,通过分析资本主义的生产方式、基本矛盾、生态危机及其相互之间的关系,批判了资本主义制度的反生态本性。资本扩张的逻辑决定了资本主义在资本积累、扩大再生产、发展经济时必然要以牺牲生态环境为代价,并将自身的生态危机向全球扩散。资本主义的双重矛盾带来了经济与生态双重危机,资本主义依靠自身的力量无法摆脱双重危机的包围,结果必然是资本主义走向不可持续性的道路。奥康纳对资本主义制度的生态学批判既有积极的意义,也有一定的理论缺陷。     

World Development and the Restructuring of the Industrial Economies

This paper reports on the joint SPM/CRANEC Catholic University of Milan symposium on “World Development and the Restructuring of Industrial Economies” held at Bellagio, Lake Como, Italy during the week of 10–15 September 1979. The symposium was organized to discuss the adjustments required by the industrialized economies when adapting to the changes inherent in present world development trends, as well as to help define national and international policy measures that might be used to facilitate the restructuring process. This report reviews the key issues, alternative strategies for restructuring, and policy measures for restructuring discussed at the symposium. It also offers some conclusions based on the results of the symposium.

The TRIPs agreement and technological innovation

In this paper we attempt to evaluate the possible spill-over of the international agreement on Trade-Related Aspects of Intellectual Property rights (TRIPs for short), underwritten in 1994, regarding economic growth for both wealthy and developing countries. We find that the TRIPs convention has prompted, at the same time, innovation in developing countries and a rise in the per capita income for all the economies involved in international commerce. As a by-product of our research we find that, despite the strong growth of resident patents application after 1995 (the year in which TRIPs came into force), most of the increase in the gross domestic product per capita in developing countries is attributable to the international transfer of technologies, via foreign direct investments.
