寿险代理人心理契约结构的实证研究

员工心理契约的研究是组织行为学研究的热点之一,但目前还没有就寿险行业的寿险代理人这一特殊人群进行研究。通过对我国寿险代理人心理契约的结构及其内在关系进行实证研究,发现在寿险代理人心理契约结构中,组织责任有交易责任、保障责任、发展责任3个因子,员工责任主要有技能与协作、关心与参与、服从与忠诚3个因子,且代理人与管理者之间在各个分量表中均存在着认知差异。     

An Empirical Agent‐Based Model to Simulate the Adoption of Water Reuse Using the Social Amplification of Risk Framework

Water reuse can serve as a sustainable alternative water source for urban areas. However, the successful implementation of large‐scale water reuse projects depends on community acceptance. Because of the negative perceptions that are traditionally associated with reclaimed water, water reuse is often not considered in the development of urban water management plans. This study develops a simulation model for understanding community opinion dynamics surrounding the issue of water reuse, and how individual perceptions evolve within that context, which can help in the planning and decision‐making process. Based on the social amplification of risk framework, our agent‐based model simulates consumer perceptions, discussion patterns, and their adoption or rejection of water reuse. The model is based on the “risk publics” model, an empirical approach that uses the concept of belief clusters to explain the adoption of new technology. Each household is represented as an agent, and parameters that define their behavior and attributes are defined from survey data. Community‐level parameters—including social groups, relationships, and communication variables, also from survey data—are encoded to simulate the social processes that influence community opinion. The model demonstrates its capabilities to simulate opinion dynamics and consumer adoption of water reuse. In addition, based on empirical data, the model is applied to investigate water reuse behavior in different regions of the United States. Importantly, our results reveal that public opinion dynamics emerge differently based on membership in opinion clusters, frequency of discussion, and the structure of social networks.     

Correlation of Quantitative Risk Results for High Hazard Processes

A quantitative risk analysis was conducted to evaluate the design of the VX neutralization subsystem and related support facilities of the U.S. Army Newport Chemical Agent Disposal Facility. Three major incidents including agent release, personnel injury, and system loss were studied using fault tree analysis methodology. Each incident was assigned a risk assessment code based on the severity level and probability of occurrence of the incident. Safety mitigations or design changes were recommended to bring the "undesired" risk level (typical agent release events) to be "acceptable with controls" or "acceptable."     

基于项目治理的代建单位选择方式研究

为处理代建单位选择方式与代建市场中的资质管理、评价机制等的相互关系，引入项目治理理论，从正式契约存在信息非对称性的问题出发，通过伙伴行为来建立信任合作关系，从而实行竞争与合作相结合的企业代建单位名录制。进一步从政府监管能力、项目自身特点、代建单位能力和代建市场成熟度等角度考虑代建单位选择，得出公开招标、邀请招标、直接委托以及政府机构集中代建等方式下的代建单位选择策略。     

用海盐石膏制备硅酸盐水泥缓凝剂和增强剂的研究

在分析、测定了海盐石膏的化学组成和矿物组成及热特性的基础上，研究了不同煅烧条件下制备的改性海盐石膏对硅酸盐水泥主要性能的影响。结果表明：改性海盐石膏既明显地提高水泥的早期强度和略提高水泥的后期强度，还能十分明显地提高高掺量混合材水泥的强度，且水泥的凝结时间正常。制备的最佳工艺参数是：锻烧温度800℃为左右，煅烧时间为0．5～1h。
