多维视角的研发团队类型及其运行特征研究

研发团队类型及其运行特征的不同,必然导致管理模式和制度安排的差异.维持研发团队内部同一性的构成边界界定了团队的结构性特征,而研发团队生命周期反映了团队的阶段性特征.从研发团队的构成边界和生命周期两个维度可以将研发团队分为任务导向型、理性自治型、利益匹配型、领导魅力型、情境互动型和愿景一致型等6种类型,不同类型的研发团队具有不同的运行特征.     

Resource Allocation in Integrated Preoperational and Operational Management of Natural Hazards

The management of natural hazards occurring over a territory entails two main phases: a preoperational —or pre-event—phase, whose objective is to relocate resources closer to sites characterized by the highest hazard, and an operational —during the event—phase, whose objective is to manage in real time the available resources by allocating them to sites where their intervention is needed. Obviously, the two phases are closely related, and demand a unified and integrated treatment. This work presents a unifying framework that integrates various decisional problems arising in the management of different kinds of natural hazards. The proposed approach, which is based on a mathematical programming formulation, can support the decisionmakers in the optimal resource allocation before (preoperational phase) and during (operational phase) an emergency due to natural hazard events. Different alternatives of modeling the resources and the territory are proposed and discussed according to their appropriateness in the preoperational and operational phases. The proposed approach can be applied to the management of any natural hazard and, from an integration perspective, may be particularly useful for risk management in civil protection operations. An application related to the management of wildfire hazard is presented.

试论模拟法庭实验教学

在法治国家,法学教育是我国法学发展的基地,法学教育与社会实践的契合是至关重要的.针对传统法学教育的不足,法学教育改革在教学内容、教学方法等方面提出了新的目标.法学实验室教育是新型的教学实验模式,模拟法庭作为其不可或缺的一部分,发挥着重要的作用.本文着重讨论模拟法庭教学模式的运行过程及实现教育改革目的的作用.     

农村快递联合体成员运作风险演化博弈研究

针对农村快递联合体成员合作过程中的风险控制问题,以农村快递联合体契约风险为研究对象,运用演化博弈理论,分析农村快递联合体中农村电商平台、快递企业和平台商户间的动态博弈过程,构建不同策略下三者的演化博弈模型,结合系统动力学对三方的平衡状态及策略选择的动态博弈进行仿真分析。结果表明:三方博弈主体在根据自身收益情况调整策略选择后,系统最终可达到平台监管企业、企业努力提升服务水平、商户积极参与联合体的稳定均衡状态。在演化博弈过程中,平台必须发挥主导作用,监督企业保证服务质量,保障商户权益,引导商户积极加入快递联合体。因此,应在快递联合体中增设专门的信息部门,构建联合体内企业综合评价体系,制定与运营合作有关的激励性和惩罚性契约协议,保证农村快递联合体的稳定运营。     

基于变位置参数贝叶斯预测银行内部欺诈研究

内部欺诈事件类型是中国商业银行最严重的操作风险类型。但由于操作风险本质特征和中国商业银行内部欺诈损失数据收集年度较短,数据匮乏,为了在小样本数据下进行更准确的度量,本文采用贝叶斯后验预测分布方法,其中,假设损失频率服从泊松-伽马分布,而损失强度服从广义帕累托-混合伽马分布,分析后验分布的形式。由于在广义帕累托分布的参数估计中,位置参数的确定对估计结果的影响很大,因此,本文采用变位置参数线性趋势的贝叶斯分析以增强参数预测稳定性,降低位置参数选择对结果产生的影响,获得中国商业银行内部欺诈损失频率和损失强度的后验预测分布和边际分布,进而采用蒙特卡罗模拟,联合损失频率分布和损失强度的预测分布获得内部欺诈的风险联合分布。与传统Poisson-GPD极值分析法相比,在险值和预期超额损失明显降低,有利于银行降低内部欺诈操作风险资本。利用贝叶斯分析获得的后验分布可以作为未来的先验分布,有利于在较小样本下获得较真实的参数估计。     

Lifecycle Pricing for Installed Base Management with Constrained Capacity and Remanufacturing

Installed base management is the policy in which the manufacturer leases the product to consumers, and bundles repair and maintenance services along with the product. In this article, we investigate for the optimal leasing price and leasing duration decisions by a monopolist when the production and servicing capacity are constrained. The effect of diffusion of consumers in the installed base is considered, with the ownership of the product resting with the monopolist during the product lifecycle. The monopolist operating the installed base jointly optimizes the profits from leasing the product/service bundle along with maintenance revenues and remanufacturing savings. We formulate the manufacturer's problem as an optimal control problem and show that the optimal pricing strategy of the firm should be a skimming strategy. We also find that the effect of remanufacturing savings on the pricing decision and the length of the leasing duration changes significantly depending on the duration of the product's lifecycle. If the product lifecycle is long and remanufacturing savings are low, the firm should offer a shorter leasing duration, whereas if the remanufacturing savings are high, the firm should optimally offer a higher leasing duration. In contrast, if the time duration of the product lifecycle is low and remanufacturing savings are low, the firm prefers to offer a shorter leasing duration, whereas if the remanufacturing savings are high, the firm should optimally have a longer leasing duration. The article also shows that if the production capacity is small, the manufacturer increases the leasing duration. If the production capacity is very small, the manufacturer sets the leasing duration to be equal to the product lifecycle and does not use remanufacturing.     

基于多元统计方法的农村合作金融机构运营效率研究——以延安地区为例

采用2010年对延安地区13家农村信用社以及当地银监局进行的问卷调查和实地访谈数据,运用因子分析和聚类分析方法,对农村信用社运营效率进行横向比较。结果表明:运营效率差异主要来源于抗风险能力、盈利能力和支农能力3个因子。结合农村信用社效率得分和经济发展状况将农村信用社分为3个层次,并提出要提高农村信用社的运营效率,需完善风险控制机制、开展业务创新、加大政府支持力度等相关政策建议。     

知识演进与动态能力构建

在揭示运作能力与动态能力的关系以及两者的知识基础上,提出一个以知识演进为基础的动态能力模型,并在知识活动与动态能力框架的3个维度之间建立起了联系.同时,利用能力生命周期概念,在动态能力、运作能力改变阶段和知识演进之间建立起紧密的联系,阐明了运作能力的改变阶段既反映动态能力的作用,又与知识演进步骤相对应,从而进一步佐证了动态能力的知识基础.
