变革型领导对员工创造力的作用机理研究

以内在动机理论为基础,探讨变革型领导行为对下属创造力产生影响的作用机理,即变革型领导通过心理授权和组织对创造力的支持作用于员工创造力,采用结构方程模型分析变革型领导、心理授权、组织对创造力的支持与员工创造力之间的关系,采用问卷调查方法进行研究.结果发现,心理授权对变革型领导和组织对创造力的支持产生中介作用,但对员工的创造力并无显著影响,说明在中国情境下,授权并不能使员工积极放心地从事创造性工作,因此在实践中领导对员工授权需谨慎;变革型领导通过心理授权和组织对创造力的支持对员工的创造力产生正向作用,验证了提出的假设,使变革型领导影响员工创造力的过程具体化和清晰化,对实践具有较强的指导意义. 通过心理授权和组织对创造力的支持作用于员工创造力,采用结构方程模型分析变革型领导、心理授权、组织对创造力的支持与员工创造力之间的关系,采用问卷调查方法进行研究.结果发现,心理授权对变革型领导和组织对创造力的支持产生中介作用,但对员工的创造力并无显著影响,说明在中国情境下,授权并不能使员工积极放心地从事创造性工作,因此在实践中领导对员工授权需谨慎;变革型领导通过心理授权和组织对创造力的支持对员工的创造力产生正向作用,验证了提出 假设,使变革型领导影响员工创造力的过程具体化和清晰化,对实践具有较强的指导意义.     

指令驱动市场中非知情交易者的最优交易策略

在非对称信息下,综合非知情交易者对资产价值的预期、私人估值及资产价值波动,构造指令驱动市场价格形成的动态模型,给出非知情交易者指令提交策略的解析解,并依此描述了非知情交易者对资产价值预期的动态更新过程.研究发现:私人估值和资产价值波动通过影响非知情交易者最优策略,使得市场进入不同均衡状态;在每个均衡状态下,非知情交易者根据资产价值的预期变化更新交易策略,进而引起知情交易者策略调整,特别地,使得知情交易者被挤出市场成为可能.进一步分析表明,私人估值、资产价值波动及知情交易者比例对市场流动性的影响依赖于每个均衡中限价指令执行风险的差异.     

股权众筹投融资方的最优策略分析

分析了股权众筹融资方和投资方的最优策略.依据股权众筹的流程,构建了股权众筹过程中投融资方利益博弈的3阶段模型,并在同时满足融资方与投资方预期收益最大化的条件下,求解了相应的最优化问题并给出了投融资方最优策略的解析式.研究结果表明,在参数满足一定条件时,股权众筹投融资方均存在最优策略,且最优策略受边际收益、项目成功概率、预期回报率等因素的影响.

Dynamic models and attainment in the workplace

The two most marked trends in recent stratification studies are: (1) the shift away from a statical approach to attainment and toward a dynamical representation of achievement, and (2) the shift away from the assumption that achievement is largely a matter of individual characteristics, and toward the view that achievement is the outcome of an employer-employee exchange of productive resources for earnings and status. This paper forges a link between these parallel trends by elaborating on previous formulations of dynamic models of achievement and applying the results to the analysis of earnings attainment in an internal labor market. The modeling section of the paper joins within a single framework the growing interest in ascertaining how a given structure of opportunity shapes achievement and in determining the different points in the career line at which individual background and resource variables impact attainment. Special attention is devoted to the problems facing researchers who wish to bring a dynamic conceptualization of achievement to cross-sectional or otherwise deficient data. Although the empirical application of the various models is largely meant to be illustrative, it is of interest in its own right because it goes substantially beyond previous efforts in this area.     

The success of protest groups: Multivariate analyses

This paper reviews earlier research and presents new analytical findings regarding the outcomes of social movements. Using the resource mobilization/management approach, empirical propositions that seek to explain protest group success or failure are tested. Based upon data gathered from a sample of 53 US protest groups, the causal models explained the majority of the variance in degree of success between these groups. Our findings indicate that protest groups which threaten to replace or destroy established groups are usually unsuccessful, and those having many strong alliances tend to be more successful than groups fighting alone. The use of violence does not greatly aid the prediction of group outcome because of the unpredictable, ambivalent reaction to violence by established groups.     

On the mode of administering a questionnaire and responses to open-ended items

Concurrently administered personal and telephone surveys are compared to measure differences between the modes for identical questions. Speed of questioning is found to be greater in telephone interviews than personal interviews. The faster pace of telephone interviews is linked to shorter answers to open-ended items on the telephone. The tendency to reduce such responses is disproportionately exhibited by younger, affluent respondents who tend to provide detailed responses in personal interviews.
