试析新闻发言人制度在中国升温原因及实践的基本准则

新闻发言人制度有其历史溯源与理论渊源,它在信息传播过程中在一定程度上具有对信息筛选、过滤的“守门人”品质。该制度在中国大陆重新升温主要因为：一、满足公众知情权的需要;二、应对海量信息、匡正视听的需要;三、SARS等突发事件的催化。客观真实、迅速及时、切中热点是新闻发言人制度在实践中必须遵循的基本准则。     

解决能力贫困是青海新农村建设的切入点

新农村建设是一项惠及亿万农民的世纪工程,其建设的长期性、艰巨性和复杂性,是由我国农村人口基数大、收入水平低、发展不平衡决定的.青海省作为西部经济欠发达省份的典型代表,新农村建设与经济发达的地区的新农村建设既不在一个起点上,也不可能达到同样的水平.青海省农村贫困的根源不是收入或消费的匮乏,而是由于教育、社会保障、健康和机会等方面的贫困而导致的“能力贫困“,新农村建设的切入点就是尽快解决农民的能力贫困问题.     

土地整治新增耕地评定方法研究

土地整治新增耕地质量评定,对提高土地整治的综合效益,完善耕地质量评定技术体系,促进土地管理科学决策有重要的理论和实践价值。本文认为,新增耕地质量建设可分为"平台"质量和"利用"质量两个阶段,国土部门的耕地分等定级主要是对耕地"平台"质量的评定,应从土地整治新增耕地特点出发,采用特尔斐法和层次分析法,将土地整治工程中的"基础设施"条件作为新增耕地质量评定重要的指标。     

新疆支农贷款在新农村建设中的效益分析

自从西部大开发政策实施以来,新疆的支农贷款逐年增多,新疆农业与农村经济也取得了很大的成就,农业生产条件比以前明显改善,但其效益不佳。本文主要运用柯布—道格拉斯函数和相关系数模型对支农贷款在新疆社会主义新农村建设中的效益进行分析,并提出相关政策建议。

The forthcoming Artificial Intelligence (AI) revolution: Its impact on society and firms

The impact of the industrial and digital (information) revolutions has, undoubtedly, been substantial on practically all aspects of our society, life, firms and employment. Will the forthcoming AI revolution produce similar, far-reaching effects? By examining analogous inventions of the industrial, digital and AI revolutions, this article claims that the latter is on target and that it would bring extensive changes that will also affect all aspects of our society and life. In addition, its impact on firms and employment will be considerable, resulting in richly interconnected organizations with decision making based on the analysis and exploitation of “big” data and intensified, global competition among firms. People will be capable of buying goods and obtaining services from anywhere in the world using the Internet, and exploiting the unlimited, additional benefits that will open through the widespread usage of AI inventions. The paper concludes that significant competitive advantages will continue to accrue to those utilizing the Internet widely and willing to take entrepreneurial risks in order to turn innovative products/services into worldwide commercial success stories. The greatest challenge facing societies and firms would be utilizing the benefits of availing AI technologies, providing vast opportunities for both new products/services and immense productivity improvements while avoiding the dangers and disadvantages in terms of increased unemployment and greater wealth inequalities.     

Can (unusual) weather conditions in New York predict South African stock returns?

This paper investigates the explanatory power of certain weather variables, measured as deviations from their monthly averages, in a leading international financial trading centre, i.e., New York, for South African stock returns, over the daily period January 2nd, 1973 to December, 31, 2015. The empirical results highlight that these unusual deviations of weather variables have a statistically significant negative effect on the stock returns in South Africa, indicating that unusual weather conditions in New York can be used to predict South African stock returns, which otherwise seems to be highly unpredictable. In fact, a forecasting exercise recommends that a trading rule that considers those weather variables through a GARCH modelling approach seems to outperform the random walk model and thus beat the market.     

Gentrifier? Who,Me? Interrogating the Gentrifier in the Mirror

Schlichtman and Patch suggest that there is an elephant sitting in the academic corner: while urbanists often use ‘gentrification’ as a pejorative term in formal and informal academic conversation, many urbanists are gentrifiers themselves. Even though urbanists have this firsthand experience with the process, this familiarity makes little impact on scholarly debate. There is, Schlichtman and Patch argue, an artificial distance in accounts of gentrification because researchers have not adequately examined their own relationship to the process. Utilizing a simple diagnostic tool that includes ten common aspects of gentrification, they compose two autoethnographic memoirs to begin this dialogue.     

The design of light-handed regulation of airports: Lessons from experience in Australia and New Zealand

The difficulties experienced with traditional forms of economic regulation of airports involving direct control of prices have led to an interest in light-handed regulatory frameworks. Experience with light-handed regulation of airports is primarily confined to Australia and New Zealand. The paper examines the design features of light-handed regulation in Australia and New Zealand in relation to the stated objectives associated with the introduction of light-handed regulation. The paper identifies important aspects associated with the design of light-handed regulation including the incorporation of a credible threat of stronger regulation and the characteristics of this, and an apparent trade-off in objectives achieved with different approaches to light-handed regulation.
