Sampling Strategies for Toxic Air Contaminants

Annual concentrations of toxic air contaminants are of primary concern from the perspective of chronic human exposure assessment and risk analysis. Despite recent advances in air quality monitoring technology, resource and technical constraints often impose limitations on the availability of a sufficient number of ambient concentration measurements for performing environmental risk analysis. Therefore, sample size limitations, representativeness of data, and uncertainties in the estimated annual mean concentration must be examined before performing quantitative risk analysis. In this paper, we discuss several factors that need to be considered in designing field-sampling programs for toxic air contaminants and in verifying compliance with environmental regulations. Specifically, we examine the behavior of SO2, TSP, and CO data as surrogates for toxic air contaminants and as examples of point source, area source, and line source-dominated pollutants, respectively, from the standpoint of sampling design. We demonstrate the use of bootstrap resampling method and normal theory in estimating the annual mean concentration and its 95% confidence bounds from limited sampling data, and illustrate the application of operating characteristic (OC) curves to determine optimum sample size and other sampling strategies. We also outline a statistical procedure, based on a one-sided t-test, that utilizes the sampled concentration data for evaluating whether a sampling site is compliance with relevant ambient guideline concentrations for toxic air contaminants.

Private Ownership versus Institutional Ownership: Exclusion Pricing of Initial Public Offerings

The authors examine the literature with respect to the pricing of initial public offerings and focus upon the relationship of pricing to the structure and conduct of the investment banking industry. Using a data base of all share offerings undertaken in the United States over a two and a half year period, the authors find that there is considerable evidence for the proposition that large, prestigious, and well capitalised investment banks tend to price their share offerings at a higher absolute level than those not meeting such characteristics. Using classical statistical methods, the authors find that the pricing strategy of investment banks is connected to their affiliation with investment funds and unit trusts. The motives for such pricing strategies, the authors argue, lie with the affiliation of investment banks with investment funds, suggesting that the pricing of new share offerings may be a means of excluding retail investors from participating in the strong returns such issues exhibit. The authors raise legal and regulatory implications of their findings in the context of the general consolidation observed within the investment banking industry.

分享经济: 研究评述与未来展望

目的/意义 互联网的迅速发展使分享经济成为一种新型商业模式,分享经济增长的潜力在于参与者的增长。拥有物质资源的消费者作为提供者参与分享经济,对经营分享经济的企业发展,提高资源利用率、减少浪费及环境可持续发展等有重要意义。 设计/方法 基于社会交换理论,构建了消费者物质主义对提供资源参与分享经济的关系假设模型,并通过问卷收集数据,运用结构方程对模型及假设进行分析与检验。 结论/发现 （1）经济价值、社会价值及情感价值在消费者物质主义与参与分享经济的关系具有中介作用。（2）不同的物质主义对参与分享经济意愿的作用机制存在差异：工具性物质主义通过经济价值、社会价值及情感价值的完全中介作用,对参与分享意愿产生显著的正向影响;而终极性物质主义对分享意愿有显著的负向直接效应,但通过经济、社会及情感价值的遮掩效应,对参与分享经济意愿产生正向的增强作用。     

利益分析视角下的公路班线客运集约化发展研究

公路班线客运集约化改革的难点在于利益关系的协调。在广泛调研和深入访谈的基础上，结合班线客运发展历程及现状，从利益分析的视角剖析了政府、企业、个体之间的利益诉求、利益冲突及利益博弈的内在机理，指出挂靠关系下企业与个体之间的利益争夺是集约化发展难以推进的根源。研究提出以当前利益分配格局为均衡点的“实收配股”集约化发展改革方案，同时强调政府应转变职能定位、完善相关政策，防止形成市场封锁或垄断。     

系列性权利组合:有限责任公司股东优先购买权性质新探

股东优先购买权体现出有限责任公司人合性与资合性之间的冲突。中国对于股东优先购买权的法律规范存在缺陷,其根本原因在于缺乏一套体系性的股东优先购买权理论。股东优先购买权本质上是系列性权利组合,而非单一的权利,具体包括资格维持请求权、告知请求权、强制缔约权和优先受领权。股东于其取得股东身份时取得优先购买权,并于此时得以行使。至于优先购买权的行使期限,则不宜做过多理论上的探讨,而应当交由立法者根据本国国情加以规定。     

生产者货币计价决定因素的实证研究

利用12个发达国家和发展中国家的非平衡面板样本数据,对微观、宏观和其他因素对生产者货币计价(PCP)的影响进行实证研究,指出经济规模、市场份额、金融市场的发达程度、币值的对内稳定性和产品差异化程度是最主要的影响因素,而出口商的谈判能力、币值的对外稳定性等因素也对PCP的选择有一定影响。根据实证检验结果,对人民币作为贸易计价货币的条件进行评估,发现其优势在于我国的经济规模、出口商的市场份额及其谈判能力以及人民币汇率的相对稳定性; 劣势在于相对落后的金融市场、不可预期性较大的通货膨胀水平以及产品的差异化程度。
