大型公共建筑工程质量保险纯费率厘定研究——基于GLM及GAM的实证比较分析

为准确地厘定大型公共建筑工程质量的保险纯费率，通过文献分析及调研，对影响大型公共建筑工程质量的因素进行了研究，提炼出11项保险费率因子。以46栋竣工于1993—2016年的大型公共建筑为工程数据集，在频率-强度法基础上，基于Poisson、Negative Binomial、Gamma、Inverse Gauss等分布的假设，利用广义线性模型及广义可加模型建立了8个工程质量保险纯费率厘定模型，通过比较选择最优模型，并对模型进行了验证。结果表明，所建模型可用于大型公共建筑工程质量保险纯费率厘定。

我国政府规划价值观的历史考察

从历史视角对我国政府的规划价值观进行系统剖析，指出我国政府规划价值观混杂着政策价值观、政治价值观、组织价值观和意识形态价值观，表现为鲜明的泛公共利益化特征，不但激化了公权力与私权利的冲突，而且对城市规划本身造成了不良影响. 城市规划权力来源于政府行政权威，政府集权制的规划决策模式是规划价值观泛公共利益化产生的主要原因. 城市规划体制转型首先要正视政府的规划价值观问题.     

EFFECT OF FORESTLAND AVAILABILITY BY OWNERSHIP TYPE ON LICENSE SALES FOR HUNTING: A SPATIAL APPROACH

Abstract The effect of forestland availability under different ownership types on license sales for hunting in nine Southeastern states is empirically evaluated. An equation that represents license sales for hunting is estimated assuming the sale of hunting licenses in a particular county is related to the characteristics of that county as well as the characteristics and license sales for hunting in its neighboring counties. The positive effects of the amounts of both national and private forestland on license sales reaffirm the potential benefits of maintaining forestland to stimulate hunting. The positive spillover effect of national forests on license sales for hunting suggests that availability and close access to hunting in national forests within neighboring counties are important in supporting hunting license sales in a county. This study contributes to the general understanding of the drivers affecting individuals’ decisions to use natural resources for hunting. Advances in natural resource modeling, specifically the spatial process model and geospatial data used in this research, make it possible to examine the interactions between the spatial dynamics and ownership attributes of the natural system, allowing policy makers to design natural resource management practices that respond to a system characterized by these interactions.     

Third-Generation Solar Cells: Toxicity and Risk of Exposure

Solar energy is considered clean energy, and its use is predicted to increase in the near future. Most installed units today are crystalline solar cells, but the field is in constant development, and when the first dye sensitized solar cell was published by Grätzel and O'Reagan a new, third-generation, solar power was born. Highly toxic metals are used to produce the photovoltaic units today, and with the predicted increase in solar cell installation, the human health hazards of these panels could become an issue. Additionally, many of these materials are used in their nanoform, which is associated with an additional risk. In this article, we discuss the technology behind the third-generation solar cells with its valuable use of nanotechnology as well as the possible health hazard when such nanomaterials are used in solar power units. We will show that the main exposure will occur either during the development and production phases or at the end-of-life stage of the solar cells, where toxic material can leach into landfills, and subsequently into the environment and impact the ecosystem directly, or humans indirectly through edible plants or drinking water.
