  • corporate social responsibility the cost of equity capital and ownership structure an analysis of chinese listed firms
    Australian Journal of Management, 2015
    Co-Authors: Duchi Liu, Jianbai Huang
    Abstract:

    This study examines the effect of corporate social responsibility (CSR) towards primary stakeholders on the cost of equity capital in Chinese listed firms, and divides the sample into state-owned enterprises (SOEs) and non-state-owned enterprises (NSOEs) for comparison. We construct a set of CSR Index Systems to measure the quality of the CSR practices and use several approaches to estimate firms’ ex ante cost of equity capital. The results show that firms with higher CSR scores have significantly lower cost of equity capital. In particular, we find that investments in improving CSR towards investors make the greatest contribution to reducing firms’ equity financing costs, and the cost of capital effects of CSR is more significant in recessions than in economic booms. In addition, SOEs have better CSR and lower cost of equity capital than NSOEs, but the effect of CSR in reducing the cost of equity capital is greater for NSOEs than for SOEs. The findings suggest that CSR toward primary stakeholders can be ...

  • quantitative assessment of groundwater vulnerability using Index system and transport simulation huangshuihe catchment china
    Science of The Total Environment, 2010
    Co-Authors: Yingying Yao, Gregory Hayes, Baoxiang Zhang, Chunmiao Zheng
    Abstract:

    Groundwater vulnerability assessment has been an increasingly important environment management tool. The existing vulnerability assessment approaches are mostly Index Systems which have significant disadvantages. There need to be some quantitative studies on vulnerability indicators based on objective physical process study. In this study, we tried to do vulnerability assessment in Huangshuihe catchment in Shandong province of China using both contaminant transport simulations and Index system approach. Transit time of 75% of hypothetical injected contaminant concentration was considered as the vulnerability indicator. First, we collected the field data of the Huangshuihe catchment and the catchment was divided into 34 sub areas that can each be treated as a transport sub model. Next, we constructed a Hydrus1D transport model of Huangshuihe catchment. Different sub areas had different input values. Thirdly, we used Monte-Carlo simulation to improve the collected data and did vulnerability assessment using the statistics of the contaminant transit time as a vulnerability indicator. Finally, to compare with the assessment result by transport simulation, we applied two Index Systems to Huangshuihe catchment. The first was DRASTIC system, and the other was a system we tentatively constructed examining the relationships between the transit time and the input parameters by simply changing the input values. The result of comparisons between the two Index Systems and transport simulation approach suggested partial validation to DRASTIC, and the construction of the new tentative Index system was an attempt of building up Index approaches based on physical process simulation.

  • an eco city evaluation method based on spatial analysis technology a case study of jiangsu province china
    Ecological Indicators, 2015
    Co-Authors: Yong Wang, Qian Ding, Dafang Zhuang
    Abstract:

    An eco-city is an eco-sustainable, balanced and intensive human settlement, and the method selected to evaluate an eco-city is an important determinant of the accuracy of the evaluation. We present a new eco-city evaluation method comprising an ecological vulnerability evaluation Index system and an economic, social and environmental evaluation Index system based on land use, economic development, social progress and environmental protection using spatial analysis technology (remote sensing (RS) and geographic information system (GIS)). We constructed an ecological vulnerability evaluation Index system using a pressure-state-response (PSR) model and the analytic hierarchy process (AHP) based on an ecological suitability Index, landscape pattern Index and land resource utilization degree Index and comprehensively evaluated the ecological vulnerability condition using principal component analysis (PCA) and an expert scoring method. We established an economic, social and environmental evaluation Index system using factor analysis. These Index Systems are associated with the GIS and the AHP, and Jiangsu Province was used as an example to verify the applicability and efficiency of the evaluation method. The results show the following. (1) The ecological vulnerability of Jiangsu is relatively low but unevenly distributed. The regions with slight, light and medium vulnerabilities comprised 79.49% of the total area. (2) Thirteen cities were divided into economic advantages type (Suzhou), environmental advantages type (Nanjing, Wuxi, Yangzhou, Zhenjiang and Taizhou), social security advantages type (Changzhou, Xuzhou and Nantong) and general type (Lianyungang, Huaian, Yancheng and Suclian). (3) The overall condition of the eco-cities was classified as middle or upper and was unevenly distributed. The eco-cities were divided into four categories and there was a gradually decreasing trend from southeast to northwest, resulting in a gradient from southern Jiangsu to middle Jiangsu and northern Jiangsu. Every city should be constructed on the basis of its weak points to achieve healthy and optimum development. The results indicated that the method is an efficient and practical process, which differs from existing methods, and makes extensive use of spatial information technology and can be widely applied to evaluate eco-cities.

  • bright white beetle scales optimise multiple scattering of light
    Scientific Reports, 2015
    Co-Authors: Matteo Burresi, Lorenzo Cortese, Lorenzo Pattelli, Mathias Kolle, Peter Vukusic, Diederik S Wiersma
    Abstract:

    Whiteness arises from diffuse and broadband reflection of light typically achieved through optical scattering in randomly structured media. In contrast to structural colour due to coherent scattering, white appearance generally requires a relatively thick system comprising randomly positioned high refractive-Index scattering centres. Here, we show that the exceptionally bright white appearance of Cyphochilus and Lepidiota stigma beetles arises from a remarkably optimised anisotropy of intra-scale chitin networks, which act as a dense scattering media. Using time-resolved measurements, we show that light propagating in the scales of the beetles undergoes pronounced multiple scattering that is associated with the lowest transport mean free path reported to date for low-refractive-Index Systems. Our light transport investigation unveil high level of optimisation that achieves high-brightness white in a thin low-mass-per-unit-area anisotropic disordered nanostructure.
