Analyzing continuous randomized response data with an indifference-zone selection procedure

A review of the randomized response model introduced by Warner (1965) is given, then a randomized response model applicable to continuous data that considers a mixture of two normal distributions is considered. The target here is not to estimate any parameter, but rather to select the population with the best parameter value. This article provides a study on how to choose the best population between k distinct populations using an indifference-zone procedure. Also, this article includes tables for the required sample size needed in order to have a probability of correct selection higher than some specified value in the preference zone for the randomized response model considered.     

Test of a Trust and Confidence Model in the Applied Context of Electromagnetic Field (EMF) Risks

Trust is an important factor in risk management. There is little agreement among researchers, however, on how trust in risk management should be studied. Based on a comprehensive review of the trust literature a "dual-mode model of social trust and confidence" is proposed. Trust and confidence are separate but, under some circumstances, interacting sources of cooperation. Trust is based on value similarity, and confidence is based on performance. According to our model, judging similarity between an observer's currently active values and the values attributed to others determines social trust. Thus, the basis for trust is a judgment that the person to be trusted would act as the trusting person would. Interpretation of the other's performance influences confidence. Both social trust and confidence have an impact on people's willingness to cooperate (e.g., accept electromagnetic fields or EMF in the neighborhood). The postulated model was tested in the applied context of EMF risks. Structural equation modeling procedures and data from a random sample of 1,313 Swiss citizens between 18 and 74 years old were used. Results indicated that after minor modifications the model explained the data very well. In the applied context of EMF risks, both trust and confidence had an impact on cooperation. Results suggest that the dual-mode model of social trust and confidence could be used as a common framework in the field of trust and risk management. Practical implications of the results are discussed.     

互动公平、委员会决策程序公平与员工决策承诺:基于公平启发理论与不确定管理理论的实证研究

借助层级团队形式制定决策,决策者能激发员工的决策承诺,确保决策的有效执行。以委员会作为决策者的层级团队为例,本文探讨了以下问题:当存在个体对自身胜任力的自信、专用性人力资本投资这两个因素的影响时,互动公平与委员会决策程序公平效应及它们之间的交互效应会发生什么变化?引入公平启发理论与不确定管理理论,本文假设并检验了上述四个因素如何交互作用于员工决策承诺。以两家大型商业银行信贷业务人员为研究对象,实证研究表明:(1)自信和专用性人力资本投资对委员会决策程序公平效应有着显著调节作用,但它们对互动公平效应的调节作用不显著;(2)当存在自信和专用性人力资本投资的影响时,较强的互动公平与委员会决策程序公平之间的交互效应更稳定一些,而较低的互动公平感知与程序公平之间的交互效应在方向上发生变化。本文有助于管理者理解"公平何时能引致员工合作"这一问题,帮助其更好地把握决策过程以获得员工对其决策的支持。本研究的假设完全基于公平启发理论(FHT)和不确定管理理论(UMT)的理论逻辑做出,实证结果与FHT和UMT的理论预测以及已有实证研究结果相一致,这意味着本研究具有较高可信性和可靠性,能为进一步理论探索提供了比较坚实的基础。
