中国经济改革的路径与特点探析

中国是一个正处于工业化过程中的发展中的社会主义国家,在这样的一个国家推动实施经济转型,绝非是一个单纯的经济体制变更过程,而是体制变革与社会转型、改革与开放、市场驱动与行政主导的一支双重变奏曲,中国经济改革的复杂性也就在于此。     

The exchange rate cycle in Argentina

This article discusses the secular volatility of output, inflation, the exchange rate, and poverty in Argentina. Inflation, currency devaluation and a wide gross domestic product (GDP) cycle have been recurrent problems in Argentina for several decades. The literature has extensively discussed those issues from different viewpoints. This study focuses on a relatively unexplored theme that may contribute to a partial explanation. It deals with the continuous tendency to equalize different profitabilities resulting, in turn, from remarkably different sectoral purchasing power parities. Thus, for any given exchange rate, an incessant tendency toward the equalization of profitabilities generates opposing inflationary and devaluatory pressures. The resulting inflation-devaluation cycle feeds income redistribution, GDP fluctuation, real exchange rate instability, and high levels of uncertainty.     

Context-Sensitive Access Control Model for Government Services

During the past two decades, e-government information systems have become less paper-based and more computer-based. Those information systems usually take the form of workflow systems. Due to the large social impact of e-government systems, computer security plays a pivotal role in ensuring its efficiency and effectiveness. Access control is one of the key aspects of computer security. Current access control models do not take into account the context of the system and its environment. In this article, we argue that a formal context-sensitive access control model can improve the development of e-government workflow systems and present a particular context-sensitive access control model. The subject of the article is a specification of the context-sensitive access control model for business processes (COBAC). By using a context-sensitive access control, it is possible to define more sophisticated access control policies that cannot be implemented by existing access control models. The COBAC's context is modeled using Web Ontology Language (OWL) in order to provide formal representation of context, rich representation of diverse contextual information, semantic interoperability between various context-aware systems, and a high degree of inference making. The presented model is applicable in different e-government systems, and supports the definition of access control policies for both simple and complex business processes. The model's prototype is verified by a case study on a real e-government business process—the national petty offense trial proceedings.

Media,Education and Corruption: Investigating the Associations

We study the interactive association of press freedom, access to media and education with a nation's corruption levels. A free press generates unbiased information that greater access to the media helps propagate; and a greater degree of education, in the same context, helps individuals apply that information. This entire process generates a vigilant and corruption‐free economy. It is therefore important to consider these factors in conjunction.
