Development of an Asset Value Map for Disaster Risk Assessment in China by Spatial Disaggregation Using Ancillary Remote Sensing Data

The extent of economic losses due to a natural hazard and disaster depends largely on the spatial distribution of asset values in relation to the hazard intensity distribution within the affected area. Given that statistical data on asset value are collected by administrative units in China, generating spatially explicit asset exposure maps remains a key challenge for rapid postdisaster economic loss assessment. The goal of this study is to introduce a top‐down (or downscaling) approach to disaggregate administrative‐unit level asset value to grid‐cell level. To do so, finding the highly correlated “surrogate” indicators is the key. A combination of three data sets—nighttime light grid, LandScan population grid, and road density grid, is used as ancillary asset density distribution information for spatializing the asset value. As a result, a high spatial resolution asset value map of China for 2015 is generated. The spatial data set contains aggregated economic value at risk at 30 arc‐second spatial resolution. Accuracy of the spatial disaggregation reflects redistribution errors introduced by the disaggregation process as well as errors from the original ancillary data sets. The overall accuracy of the results proves to be promising. The example of using the developed disaggregated asset value map in exposure assessment of watersheds demonstrates that the data set offers immense analytical flexibility for overlay analysis according to the hazard extent. This product will help current efforts to analyze spatial characteristics of exposure and to uncover the contributions of both physical and social drivers of natural hazard and disaster across space and time.     

唐代御史厅壁记写作的文学与文献学价值——以李华､柳宗元厅壁记写作为例

“厅壁记”是镌刻在古代衙门的墙壁上,记述历代职官沿革、制度得失、官员迁转等,具有警示教育意义的一种文体.唐代御史的厅壁记写作重视“法”的作用,有些甚至上升为国家意志,与粉饰太平的馆阁文学大不相同,是中国法制史上浓墨重彩的一笔.唐代御史的厅壁记写作有着独特的文学价值:(1)李华、柳宗元的诸多厅壁记均用散体文写就,简洁真切,议论精警,已开中唐古文运动的先声.(2)唐代御史在厅壁记创作中注入鲜明的主体意识,语言辛辣,发人深思.唐代御史厅壁记的文献学价值表现在:一是订补现存史志文献之阙,促进唐史研究的深入;二是有助于对唐代文学发生背景的了解.唐代御史厅壁记因观览人数较多,其公众宣传、社会传播、舆论导向之作用亦不可忽视.     

人化自然背景下自然的目的性新论

自然有没有目的性，如果有的话，是在什么意义上讲的，自然的目的性是否具有层次性，我们应该如何对待这些不同形态的自然及其目的性，等等。这个问题，不同的价值观和思维方式的回答是不同的。一般来说，机械论和传统唯物主义是否定自然的目的性的，西方传统中占主导地位的理性主义往往形成自然与社会、物质和精神、理性与非理性等等二元因素的对立。而儒家、马克思的实践哲学明确主张，或从现代现象学可以推断出，自然界不但存在着目的性、主体性，而且存在着它们的差异性，如马克思强调在实践活动的基础上自然与历史的一体化，而儒家的仁爱是有差等的爱，不是墨家所说的具有绝对主义倾向的“兼爱”。也就是说，自然界中的一切生命，按照从高到低的价值顺序，微生物、植物、普通动物、人，都是具有独立的意志和价值的生命体。在道德的理想性、超越性上，它们是平等的，都是爱和尊重的对象，而在现实性上，它们对人的价值是不同的，人们对待它们的态度也应该是不同的，即是有差等的。     

The role of leadership in shared value creation from the public’s perspective: A multi-continental study

Porter and Kramer’s concept of creating shared value (CSV) has been welcomed as an approach to corporate social responsibility (CSR) among corporations that also provides a practical opportunity for dialogue in public relations, but it has been little examined from the general population’s (i.e., the public’s) perspective. Such scrutiny is important because its findings enable public relations to contribute to the debate and development of CSV from both the public’s and the organization’s viewpoints. Additionally, if public relations professionals understand how the public perceives CSV, they can give a strategic perspective to top management for maximizing moral capabilities of the business and formulate effective communication to promote CSV initiatives. This study investigates whether the public prefers corporations to practice CSV as opposed to intrinsic CSR as a separate pursuit from business interests. It also explores the role of leadership as an influential and ethical construct in implementing effective CSV as perceived by the public. The public’s preference for CSV over intrinsic CSR was revealed in a survey of 1784 participants in the United States (US), Germany, and China. Factor analysis results further suggested that effective CSV competencies of CEOs were construed as a unidimensional concept in the US, but German and Chinese participants viewed it as two-dimensional. The public perceived that leaders’ moral character played a more important, core role in effective CSV than did altruistic and behavioral attributes, across nations. Network analysis of the perceived effective CSV-characteristics provides further implications for CSV communication.     

怀疑主义与认知价值

当代知识论越来越重视认知价值的研究，但从认知价值角度去重新思考传统怀疑主义问题的研究却很少。历史上的怀疑主义者既认为我们无法拥有任何知识，又主张我们应该悬置判断。因此，他们不仅预设了一个高的知识标准，而且预设了一个价值标准：任何达不到知识标准的认知状态都是没有认知价值的。但这个价值标准是错误的，所以我们即使无法达到怀疑主义者所设定的知识标准，也不必悬置判断。假设怀疑主义者认为我们无法拥有任何知识，同时认可“有些达不到知识标准的认知状态也有认知价值”，那么怀疑主义就没有很大的威胁性，因为即使我们无法获取知识，也可以获得具有认知价值的东西，取得认知进步。此外，摩尔主义、语境主义、溯因主义这几种对怀疑主义的主要回应是否成功，最终都依赖于对认知价值的讨论。     

‘Scarier than another storm’: values at risk in the mapping and insuring of US floodplains

How do people respond to the ways in which insurance mediates environmental risks? Socio‐cultural risk research has characterized and analyzed the experiential dimension of risk, but has yet to focus on insurance, which is a key institution shaping how people understand and relate to risk. Insurance not only assesses and communicates risk; it also economizes it, making the problem on the ground not just one of risk, but also of value. This article addresses these issues with an investigation of the social life of the flood insurance rate map, the central technology of the U.S. National Flood Insurance Program (NFIP), as it grafts a new landscape of ‘value at risk’ onto the physical and social world of New York City in the aftermath of Hurricane Sandy. Like other risk technologies, ubiquitous in modern societies as decision‐making and planning tools, the map disseminates information about value and risk in order to tame uncertainty and enable prudent action oriented toward the future. However, drawing together interview, ethnographic, and documentary data, I find that for its users on the ground, the map does not simply measure ‘value at risk’ in ways that produce clear strategies for protecting property values from flooding. Instead, it puts values‐beyond simply the financial worth of places‐at risk, as well as implicates past, present, and future risks beyond simply flooding. By informing and enlarging the stakes of what needs protecting, and from what, I argue that plural and interacting ‘values at risk’ shape how people live with and respond to environmental risks that are mediated by insurance technologies.     

股权质押与市值管理:基于中国沪深股市A股上市公司的实证检验

本文以沪深两市上市公司为研究对象，基于2012-2016年的样本数据，运用STATA14探讨了上市公司发生股权质押后，相较不存在股权质押的公司是否会更有可能进行市值管理，以及股权质押、股权激励和市值管理三者之间的传导机制。基于相关数据的实证结果显示，控股股东在发生股权质押行为后，为了避免股价发生异常波动或者持续下跌从而引发公司治理层面的风险，相较不存在控股股东股权质押情形的公司的确更有可能进行市值管理；进一步分析发现，股权质押后，控股股东会通过股权激励这种手段来进行市值管理。     

基于优先权拍卖的产能分配机制研究

本文考虑一个供应商和两个独立零售商构成的供应链系统。当供应商的产能受到约束时，零售商可能会竞争有限的产能。本文提出将“优先分配权”作为一个有价值的标的物进行拍卖，按照出价高低确定优先分配顺序。本文证明了优先权拍卖机制属于共同价值模型，并提出了两类拍卖机制：事先拍卖和事后拍卖。本文证明两类优先权拍卖机制均会促使零售商提交真实的需求作为订单量，并且满足收益等价定理。而就供应商期望利润而言，事后优先权拍卖机制要高于事先优先权拍卖机制。     

Effects of Firm-specific and Country-specific Advantages on Relative Acquisition Size in Service Sector Cross-Border Acquisitions: An Empirical Examination

Using a sample of 348 service sector cross-border acquisitions by U.S. firms in 44 countries during 1990–2006, our study seeks to identify factors that influence relative acquisition size (acquisition transaction value as a percentage of acquiring firm's asset value). Our findings indicate that firm-specific advantages (FSAs) in the form of available financial slack and target industry knowledge were positively associated with relative acquisition size. However, contrary to expectations, we observed a negative relationship between cross-border acquisition experience and relative acquisition size. In addition, our results suggest that country-specific advantages (CSAs) associated with higher market potential, lower political risk, and greater cultural similarity contributed to increased relative acquisition size in service industry cross-border acquisitions. Finally, our analysis reveals that the relationship between available financial slack and relative acquisition size is contingent on cultural similarity with the relationship being more pronounced when cultural similarity is high.     

Value drivers of social businesses: A business model perspective

Hybrid organizational forms that combine commercial and welfare institutional logics play an increasingly important role in addressing the grand societal challenges we face today. Building on the literatures on hybrid organizations and social business models, we explore the characteristics of social businesses from a business model perspective. This study seeks to better understand the particularities and value drivers of hybrid social purpose in contrast to purely commercial business models. We follow a grounded theory approach and our findings are based on interview data from 17 social business firms. Building on social businesses' identified particularities, we propose four value drivers of social business models: 1) responsible efficiency, 2) impact complementarities, 3) shared values, and 4) integration novelties. We link our findings to the literature, contributing new insights into social businesses models and implications for practitioners.
