生态型城市建设的碳金融支持机制研究

全球气候变暖问题日趋严重,城市化和工业化进程加快,对于建设生态型城市有迫切需求。但是中国生态型城市建设面临产业转型困难、生态技术落后、生态意识淡薄,法律法规滞后等问题,低碳生产、低碳建筑、低碳办公、低碳交通、低碳生活、低碳旅游、低碳教育等构成了有效的生态型城市建设模式。碳金融机制能够从碳金融业务、碳基金、碳金融工具、金融市场、金融机构等多方面支持中国生态型城市建设。     

Fine-scale conservation planning outside of reserves: Cost-effective selection of retention patches at final harvest

Retaining forest patches at final harvest is a key conservation measure in boreal forests, but guidelines for how to increase its cost-effectiveness are lacking. In a study in boreal Sweden, we compared the cost-effectiveness of three different approaches a forest owner may use to select patches: selection based on the conservation value of patches alone, economic cost alone or both of them combined. We also compared the cost-effectiveness of six different common types of patches. Conservation value was measured as species richness of bryophytes and lichens and as structural characteristics of patches. Compared to the selection approach in which both conservation value and cost were used, cost-effectiveness was 5-14% lower when only conservation value was used, depending on how conservation value was measured. On the contrary, using only the economic cost decreased the cost-effectiveness by only 1-2%. Among the patch types, swamp forest areas and deciduous tree groups were cost-effective types to retain. However, the patch types were complementary in their species composition and all hosted unique species. We argue that, ideally, assessments of both conservation values and economic costs of retaining patches should be made prior to harvest to enable planners to make well-informed and cost-effective decisions.     

大学生社会主义核心价值观内化的策略研究

市场经济条件下,多元文化的冲击使当代大学生的价值目标从理想主义趋向关注现实,使大学生的价值观念由集体主义趋向关注个人。在大学生价值观教育中,要实现社会主义核心价值观的内化,应坚持整体性原则,营造良好的育人环境;要发挥榜样激励作用,开展典型示范教育;要积极搭建社会平台,加强大学生社会实践;要创新教育形式,发挥新媒体的优势。     

酒店管理专业实习过程管理研究

专业实习是酒店管理专业学生学习过程中必不可少的实践教学环节,从形式上来说,几乎所有的酒店管理专业都比较重视专业实习环节,但通常情况下,实际的实习效果和预期的实习目标之间还存在着较大偏差。针对酒店管理专业实习现存的各种问题,通过问卷调查、实习日志阅读、师生交流等方式进行信息搜集和探索研究,意在为酒店实习的过程管理提供相应对策,改善实习效果,实现酒店管理专业的可持续发展。     

《大乘大义章》与印度佛教中国化

《大乘大义章》是研究罗什与慧远佛学思想的重要著作,也是研究印度佛教思想和印度佛教中国化的重要著作。《大乘大义章》显示出罗什与慧远在佛学思想上的差别,同时也反映出中印佛教文化在本质上的不同。这两种不同文化的冲突预示着印度佛教中国化的发展方向。     

Non-convexities and the gains from concealing defenses from committed terrorists

How should countries defend against committed terrorists who attack until defeated? We identify a fundamental non-convexity—one only needs to defeat the terrorist once. Consequently, provided a country values targets similarly, it should conceal defenses and allocate defense resources randomly.     

CHH际资本流入的贸易增长效应分析

以汇率和经济增长作为国际短期资本影响国际贸易的中间变量,采用Eviews6．0,从总体上考察国际资本流入对我国进出口的影响。从模型得出,随着FDI的增加,我国的出口额会增加,进口额会减少,而短期内FDI的增加对我国的进出口都起着促进作用;人民币实际有效汇率的贬值无论在长期和短期都对出口起着促进作用,对进口起着抑制作用。因此,在国际资本大量流入的情况下,只有积极吸引FDI,有效防范短期资本大幅度波动,才能保持贸易收支的相对稳定。     

双边间接网络效应对平台产品扩散与定价的作用研究

本文在BASS扩散模型的基础上,引入双边间接网络效应的作用,建立平台产品的扩散模型。研究发现:双边间接网络效应产生潜在的市场规模扩张,其和市场单边自扩散共同作用,使得平台产品的扩散形态可能呈单峰或多峰形状。按双边扩散表现为相互制约还是相互促进,平台产品市场扩散可分为潜在市场规模扩张起飞前和潜在市场规模扩张起飞后两个阶段。平台运营者需要正确判断产品扩散所处的阶段,谨慎制定正确的定价策略。     

户外休闲坐具设计影响因素与设计原则研究

户外休闲坐具不仅是城市居民休闲生活的主要用具,也是城市公共设施的重要构成元素。目前城市户外休闲坐具存在数量不够、设计不符合人体工程学、坐具设计与设置忽视人的行为与心理等问题,根据＂人-机-环境＂的系统观,分析了户外休闲坐具设计受到休闲主体——人、休闲坐具本身以及休闲环境三个关联因素的影响,提出了户外休闲坐具设计应把握人性化、与公共环境协调、耐久性与安全性、功能性、系统性等六大设计原则。     

Speculative dynamics

We develop a method for solving for equilibrium outcomes in stationary strategic settings in which speculators are informationally large and understand how their actions affect the information content of prices. This allows us to characterize speculation by institutional investors who receive private long-lived information on a recurring basis, and trade strategically. When the underlying asset value process has a stationary autoregressive structure, we develop a contraction mapping argument to solve for the stationary linear equilibrium. We derive analytically and numerically how the characteristics of private information—its quantity, persistence and correlation, and division among speculators—affect trading profits, pricing and trading strategies. Our central finding is that what matters for equilibrium outcomes are the most recent signals that speculators receive. Speculators trade so much more aggressively on new information than old that the bulk of their profits come from their two or three most recent private signals. Trading on past prices drops off faster yet; effectively only the most recent price matters.
