生活垃圾焚烧发电烟气处理技术应用

生活垃圾是阻碍我国城市化发展的主要因素.近年来,中国的环境保护标准有了显著提高,以往广泛建立垃圾填埋场处理城市生活垃圾的模式已无法满足新时代的新要求.目前,我国垃圾处理主要采取填埋、堆肥以及焚烧发电的方式,焚烧发电不仅能够减少垃圾容量,还不会污染地下水源、土壤,所焚烧的热量,还可用于发电、供热,逐渐成为生活垃圾处理的主要方式.本文主要分析如何运用生活垃圾焚烧发电技术,处理好烟气问题.     

高速公路收费站车道通行能力分析

高速公路是人们出行选择的重要交通资源,影响人们选择高速公路出行的重要因素是高速公路通行能力即高速公路是否拥堵.高速公路收费站拥堵状况影响着高速公路路段的拥堵状况,因此提高收费站通行能力可以改善整体公路运行状况.本文将从高速公路收费站交通条件和管制条件进行通行能力分析,针对目前影响通行能力问题,提出提高通行能力的建议,为高速公路收费站工程建设提供参考.     

Forecasting the volatility of asset returns: The informational gains from option prices

A new class of forecasting models is proposed that extends the realized GARCH class of models through the inclusion of option prices to forecast the variance of asset returns. The VIX is used to approximate option prices, resulting in a set of cross-equation restrictions on the model’s parameters. The full model is characterized by a nonlinear system of three equations containing asset returns, the realized variance, and the VIX, with estimation of the parameters based on maximum likelihood methods. The forecasting properties of the new class of forecasting models, as well as a number of special cases, are investigated and applied to forecasting the daily S&P500 index realized variance using intra-day and daily data from September 2001 to November 2017. The forecasting results provide strong support for including the realized variance and the VIX to improve variance forecasts, with linear conditional variance models performing well for short-term one-day-ahead forecasts, whereas log-linear conditional variance models tend to perform better for intermediate five-day-ahead forecasts.     

Earthquake triggered networked risk and response: based on relevant literature

Death, injury, conflict, and disorder caused by natural and man-made disasters have resulted in significant challenges to good governance and impeded the goal of achieving the benign development of society. This paper uses a particular method for analyzing the research situation and identifying current trends and focuses. It then proceeds to explore future research needs. The study finds that future researchers will shift their emphasis from the risks caused by natural disasters to those arising from man-made disasters; meanwhile, the study will consider the complex systems of interaction to understand causality. The objectives of management, hence, should change from investigating the impacts of risks to crisis control. Eventually, an evolutionary disaster-based social-risk framework is established, and some suggestions for future research are provided.

新兴大国面临着推动经济持续增长和转型的任务,走自主创新道路是一种必然选择。进入新世纪以来,＂金砖四国＂的增长竞争力在上升,除俄罗斯外的三国创新能力也在上升。应该借鉴发达国家的成功经验、新兴大国的实践经验,从创新主体、创新内容和创新环境上构建自主创新道路的框架,并致力于完善创新机制、掌握关键核心技术、发展战略性新型产业和加强国际技术合作交流。     

A MIXED NASH–WALRASIAN EQUILIBRIUM MODEL WITH ENDOGENOUS STEALING AND ENDOGENOUS SPECIALIZATION

Abstract. Using a price vector and a conjecture about a population's activities, this paper suggests that a mixed Nash–Walrasian equilibrium (NWE) occurs if, when every individual maximizes her utility under her conjecture, the trading markets and the theft ‘markets’ are all cleared. Thus, in our model the property rights system, instead of giving protection directly to producers, is aimed mainly at discouraging illegal behaviour. As a result, the equilibrium of the economy is seen to depend not only on self‐protection and/or the legal system itself, but also on the transportation efficiency of the economy.     

Liquidity, Quality, Production Cost, and Welfare in a Search Model of Money

This paper examines a search model of money with divisible commodities of high and low quality, while keeping the assumptions of indivisible money and unit-inventory constraint. With no direct barter and a higher fixed cost of producing high relative to low quality, an increase in the money stock encourages the production of high-quality output by trading off the larger trading opportunities against the significance of higher fixed cost. As long as the fixed-cost differential between high and low quality is sufficiently small relative to the utility gain from high-quality consumption, the quality improvement outweighs the negative effect of higher money stocks on aggregate production, and hence implies higher welfare.     

论我国企业知识产权管理战略

我国企业知识产权存在的问题包括知识产权保护意识薄弱、知识产权流失严重、知识产权管理弱化、知识产权纠纷增多等方面,为此,应完善知识产权管理系统、实施知识产权战略、建立科技创新机制、实现知识产权的经济效益,构建科学的知识产权价值评估体系,重视知识产权专门人才的培养。     

中国城市群规划的创新理念

在全球经济一体化的新形势下，在快速城市化过程中，我国的城市群发展很快，许多省市正在编制城市群规划，出现了城市化高度发展的新局面。当前，不少省市领导非常重视对重点地区群进行规划设计（如长三角、珠三角、山东、辽宁等地），继各地城镇体系规划与大都市区（含都市群）的概念规划之后，义掀起了“城市群规划”的新高潮。这充分体现了党中央、国务院关于“城乡统筹规划”以及贯彻科学发展观的精神。
