区域性节能潜力测算:概念解释与方法综述

从节能潜力的内涵和分类入手,综述了国内外区域性节能潜力的测算方法。基于较为完善的能源数据库,国外对区域节能潜力的研究,主要采用两种模型:自上而下的能源经济模型和自下而上的能源技术模型。国内节能潜力的研究,因缺乏相关数据的支持,尤其是省级能源数据库,研究方法相对单一。     

一种S型的超宽带左手结构设计

文章在对S型左手材料结构进行理论分析的基础上，提出一种S型超宽带左手结构。通过电磁仿真软件Ansoft HFSS对该结构的电磁波反射、透射特性进行模拟，并运用NRW方法从中提取出该结构的有效介电常数和有效磁导率。结果表明：在55．5～66．5GHz频带内，该结构具有稳定的双负特性，相对带宽为9％，这对当前超宽带左手材料...     

Improved Neymanian analysis for 2K factorial designs with binary outcomes

2^K factorial designs are widely adopted by statisticians and the broader scientific community. In this short note, under the potential outcomes framework, we adopt the partial identification approach and derive the sharp lower bound of the sampling variance of the estimated factorial effects, which leads to an “improved” Neymanian variance estimator that mitigates the overestimation issue suffered by the classic Neymanian variance estimator.     

关于医院管理人才队伍建设的思考

随着医药卫生体制改革的不断深入,医学模式、就医观念的转变,医院在医疗市场中的竞争更加激烈,传统的管理模式已经不再适应现代化医院的发展,要实现科学的、高水平的医院管理,就必须培养和造就一支能够担当重任、精通业务,并且掌握现代管理理论的高素质管理人才队伍,以适应新的形势,迎接新的挑战。     

基于市场势差论的企业对利润的追求

传统经济学认为企业应以获取最大利润为目标,现代博弈论则认为企业应获取合理利润。在成本一定的条件下,企业利润的大小无疑与其产品的市场价格有密切关系。市场上商品价格是由供求规律决定已被认为是必然,但市场上商品价格的走势却常常出现与供求规律相悖的现象,因而商品的供求不是决定其价格的唯一因素,而是重要因素之一。市场上商品价格是由市场势差决定的。企业利润的大小是由其产品在市场中势差的大小决定的。     

Potential for electric vehicle adoption in Australia

Data from the New South Wales (NSW) Household Travel Survey (2014/15 NSW, T. f. (2014/15, 9/15/2016). SA3 Household Travel Survey (HTS). Retrieved from https://drive.google.com/open?id=0B12S3-OIR0hOT3oyYzJnMVp1UWs [Google Scholar]) was analyzed to determine the trip-by-trip range of automobile travel in NSW. The results show that 88% of trips were less than 30?km, which could readily be provided by electric vehicles, consuming a total of 18?GWh in electrical energy per weekday. Even if all electric vehicles were recharged from non-renewable coal-fired power plants, the greater efficiency of electric vehicles would result in a reduction of greenhouse gas emissions across NSW by 18% carbon dioxide equivalent (CO_2(eq))_. Additionally, we mapped the average state of charge distribution of the electric vehicles at key times during the day, indicating the maximum net load (for recharging) and/or available energy (for vehicle-to-grid services) across NSW. The results are consistent with other international studies and demonstrate the potential for wide scale electric vehicles adoption in Australia.     

Methodological ignorance: A comment on field experiments and methodological intolerance

Glenn Harrison [Journal of Economic Methodology, 2013, 20, 103–117] discusses four related forms of methodological intolerance with respect to field experiments: field experiments should rely on some form of randomization, should be disconnected from theory, the concept of causality should only be defined in terms of observables, and the role of laboratory experiments is dismissed. As is often the case, the cause of intolerance is ignorance, as it is here. To acquire knowledge about potential influences, which we need for both the evaluation of internal and external validity of experimental results, we cannot do without theory. A purely empiricist (inductive) methodology will be unable to give us sufficient understanding of the validity of these results. An account of causality only based on directly observed things, is an account based on factual influences only. This account will be too restricted, because it will not deal with the unobserved potential influences, which we need – again – for the evaluation of the internal and external validity of the experimental results. Every investigation in a laboratory that is feasible regarding a specific potential influence may lead to deep knowledge. It is simply scientifically irrational to dismiss this kind of knowledge.     

可持续旅游发展的文化动因探讨

矛盾是事物发展的动力与源泉。旅游业要保持持久发展的能力，必须有推动其发展的持久动力。旅游文化的可持续发展主要体现在以下三点：旅游文化的大众服务性；旅游文化的继承性和创造性；旅游文化的时空性。     

How Does Nationalist China Fare in the Aftermath of its U. N. Defeat

This paper tries to measure the effectiveness of the Bush administration's hardline policy toward North Korea. The Bush security team is seen basically trying to discipline North Korea by employing more sticks and less carrots than its predecessor did. However, it is not quite clear whether a rather strong policy could promote efficiently both the national interest of the U.S. and the partisan interest of the Bush administration.     

以色列经济高速发展中主观隐形性因素的分析

以色列经济从建国以来一直保持着高速的发展。以色列经济高速发展的原因有内部因素和外部因素两方面，内、外因素都有客观直接性因素和主观隐形性因素。关于以色列经济的发展，在强调客观直接性因素发挥重大作用的同时，不能忽视主观隐形性因素的影响。
