Communicating Actionable Risk for Terrorism and Other Hazards⋆

We propose a shift in emphasis when communicating to people when the objective is to motivate household disaster preparedness actions. This shift is to emphasize the communication of preparedness actions (what to do about risk) rather than risk itself. We have called this perspective “communicating actionable risk,” and it is grounded in diffusion of innovations and communication theories. A representative sample of households in the nation was analyzed using a path analytic framework. Preparedness information variables (including content, density, and observation), preparedness mediating variables (knowledge, perceived effectiveness, and milling), and preparedness actions taken were modeled. Clear results emerged that provide a strong basis for communicating actionable risk, and for the conclusion both that information observed (seeing preparedness actions that other have taken) and information received (receiving recommendations about what preparedness actions to take) play key, although different, roles in motivating preparedness actions among the people in our nation.     

Power and dependence perspectives on outsourcing decisions

Since the 1980s outsourcing has been a major topic in both economic and management literature. Economic literature tends to focus on the transaction cost perspective. In management literature the core competence approach prevails. An emerging alternative view on outsourcing is the power and dependence perspective. Aspects of power and dependence become visible in four case studies involving the maintenance of capital assets. In each instance both the buyer and supplier sides of the dyad are examined. The paper concludes with managerial implications and research opportunities.

由表及里:地方服务型政府建构向度研究

服务型政府效能化与人本化建构是公共管理发展的基本向度,也是我国政府体制改革的目标.多年来,我国地方政府体制改革林林总总,风生水起.但是,由于受转型背景的复杂性、体制体系的惯性以及传统社会结构的粘性等因素制约,总体仍处于表象层面.为此,需要相应支点结构性的循序移位,由表及里,实现地方政府体制改革的路径创新,从而把技术性、手段性改革转变为真正为人民服务的体制性改革.     

增强青海经济活力问题研究

本文首先运用数量分析法对西北五省区经济活力进行排位,其结果是:青海经济活力综合指数低于陕西和新疆,高于宁夏和甘肃,位居西北五省区第三。在此基础上,梳理和分析了制约青海经济活力的主要因素,最后提出了进一步增强青海经济活力的主要措施与路径。     

权威重构:司法公开机制的新视角

从新意识形态研究范式论证司法公开正当性成为人们的惯常路径,其最大问题是忽视司法公开及其保障机制背后的非法律因素、资源配置或司法体制方面的问题.实际上,司法公开成为一种司法技艺.通过赋予程序选择权、参与权,司法公开机制勾连当事人和社会公众力量互动,最终激活了司法机关权威的“重生”.     

生态文明建设视角下创新大学生党建工作的路径研究——以宿州学院为例

大学生党员是生态文明观念的传播者,更是推进生态文明建设的先锋队和主力军.当前,在校大学生党员在生态文明方面存在一些意识淡薄与行为失范的问题.高校学生党建工作应以这些问题为导向,分析其在学校生态教育、基层党组织、生态道德修养等方面的成因,找到解决问题的对策.在此基础上,围绕生态文明建设来探索大学生党建工作的路径,如创新党支部设置方式和党建工作模式、丰富宣传教育形式、提升党员服务能力、开展实践活动、构建党员评价体系等,以提升大学生党员的生态文明意识与实践能力.     

中国工业行业碳强度的因素分析——基于超越对数生产函数

为探究工业行业碳强度变化的成因,基于Kaya恒等式的碳强度分解,以碳强度表示产出,以经济增长、能源消费量、能源消费结构和技术进步为投入要素构建超越对数生产函数,通过各要素的碳强度产出弹性反映各要素对碳强度的贡献;并运用通径分析法进一步揭示各要素间的相互关系及其与碳强度的直接和间接关系。结果表明:能源消费结构的优化和技术进步抑制了工业行业碳强度的增长,能源消费量的增长和工业增加值的增长拉动了碳强度的增长,其中能源消费结构和能源消费量对工业行业碳强度的影响显著,因此降低工业行业碳强度的关键在于减少能源消费结构和能源消费量的碳强度产出弹性;能源消费量、工业增加值和能源消费结构对能源消费量的碳强度产出弹性起直接推动作用,技术进步起直接抑制作用;工业增加值和能源消费量对能源消费结构的碳强度产出弹性起直接推动作用,技术进步和能源消费结构起直接抑制作用。可见,工业行业对能源消费的依赖性较强,降低工业行业碳强度应主要依靠技术进步转变能源利用方式,提高能源效率,优化能源消费结构。     

A combinatorial study of two-periodic random walks

Two-periodic random walks have up-steps and down-steps of one unit as usual, but the probability of an up-step is α after an even number of steps and β = 1 ? α after an odd number of steps, and reversed for down-steps. This concept was studied by Böhm and Hornik^{[2 Böhm, W.; Hornik, K. On two-periodic random walks with boundaries. Stoch. Models 2010, 26, 165–194.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]]}. We complement this analysis by using methods from (analytic) combinatorics. By using two steps at once, we can reduce the analysis to the study of Motzkin paths, with up-steps, down-steps, and level-steps. Using a proper substitution, we get the generating functions of interest in an explicit and neat form. The parameters that are discussed here are the (one-sided) maximum (already studied by Böhm and Hornik^{[2 Böhm, W.; Hornik, K. On two-periodic random walks with boundaries. Stoch. Models 2010, 26, 165–194.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]]}) and the two-sided maximum. For the asymptotic evaluation of the average value of the two-sided maximum after n random steps, more sophisticated methods from complex analysis (Mellin transform, singularity analysis) are required. The approach to transfer the analysis to Motzkin paths is, of course, not restricted to the two parameters under consideration.
