Complementary person-supervisor fit: An investigation of supplies-values (S-V) fit,leader-member exchange (LMX) and work outcomes

By applying the supplies-values (S-V) fit approach from the complementary person-environment (P-E) fit literature to the leader-employee perspective, and drawing upon social exchange theory, we examine how fulfillment of different work values is related to Leader-Member Exchange (LMX) and work outcomes. First, polynomial regression analyses combined with response surface analysis of data collected at two time points (N = 316) showed that LMX (Time 2) was higher the more the leader fulfills the employee's work values (Time 1). Second, LMX (Time 2) was higher when leader supplies (Time 1) and employee work values (Time 1) were both high than when both were low. Third, analyses of data from a sub-sample of matched leader-employee dyads (N = 140), showed that LMX (Time 2) played a mediating role on the relation between S-V fit (Time 1) and work outcomes (Time 2). Specifically, we found eight out of 10 relationships between S-V fit (Time 1) and leader-rated task performance and OCB (Time 2) to be fully mediated by LMX (Time 2). LMX (Time 2) partially mediated the relation between S-V fit (Time 1) and job satisfaction (Time 2) as only two out of five relationships were fully mediated.     

幼儿园表演区游戏开展中存在的问题及解决对策——以某幼儿园大班表演区游戏《小熊请客》为例

现如今大多数幼儿园将表演游戏融入区域活动中，作为表演区游戏开展活动之一，这一转变，在实践层面上有许多值得研究的问题。文章通过对某幼儿园大班表演区游戏的观察研究发现，表演区游戏在开展中存在场所设置不合理、材料投放单一高控、游戏参与积极性低等问题。为此提出相应的解决对策：游戏前准备适宜的场地、丰富的内容、多样的材料；游戏中细心观察，适时引导，指导过程中注意重游戏轻表演；游戏后共同分享交流，解决游戏中出现的问题，以此更好地发挥表演区游戏的实际效用。     

Impact of an Overt Response System on Staff Performance and Maintenance of Computer-Based Instruction

Interactive Computer Based Instruction (CBI) systems involve teaching strategies to facilitate greater response opportunities during training in an effort to improve learner performance. The current study investigated the effect of online staff training videos with and without overt response requirements on posttest and maintenance test scores across six block-randomized instructional modules for four employees of a university located in the southeastern region of the United States. The overt response consisted of multiple-choice questions administered throughout select teaching modules using an alternating treatment design. Findings suggest that learning occurred as a result of the CBI training; however, the effectiveness of the overt response system varied across individuals, with no discernible differentiation between learning gains associated with response requirements. Other areas of research for expanding the efficacy of CBI and overt response systems are highlighted.     

Measuring operational excellence: an operational excellence profitability (OEP) approach

The pursuit of operational excellence in the manufacturing industry is at rise but its measurement still lacks of appropriate indicators to determine its financial benefits. The ambiguity is due to the impact arisen from manufacturing fluctuations such as price and cost, production mix and direct and indirect parameters variations. Manufacturing fluctuations distort the cost benefit of operational excellence. This paper, therefore, proposes the OEP (Operational Excellence Profitability) indicators to isolate the impact of manufacturing fluctuation and distinctly identify the payback of operational excellence strategies and initiatives through cost benefits of achieving higher efficiency and yield. The paper presents the conceptual and mathematical development of the proposed OEP indicators and the formulas used for their calculation. Hypothetical and industrial-based investigations and applications of the OEP indicators are conducted for their validation. The results obtained from the hypothetical exercise and industrial case suggest that OEP indicators can provide an effective cost-benefit analysis of operational excellence. This would contribute in providing manufacturing organizations with more complete information regarding the performance of their processes, which will allow their directors and managers to take better decisions related to the management and improvement of their processes.     

碳金融市场下基于模糊测度和Choquet积分的碳期权估值

基于投资者对投资财富和风险的偏好研究碳期权定价模型。运用λ-可加模糊测度表示投资者对碳期权价值模糊度量的差异性，借助Choquet期望积分构建投资者的期望收益效用函数；根据投资财富效用最大化推导无约束条件下碳期权的最优价；结合现实约束条件，构建投资财富效用最大化下的碳期权定价模型；通过数值计算分析效用函数、模糊参数和现实约束对碳期权定价的影响。研究结果表明:效用函数的选择会体现投资者对碳期权投资风险态度的变化，模糊测度参数的取值能够反映碳期权投资者个体的主观情绪和市场信息获取程度，现实约束会迫使碳期权投资者放弃部分投资隐含价值。     

风险投资对中国新三板挂牌企业绩效的影响

风险投资是推动“大众创业、万众创新”的新型金融工具和重要资本力量，对产业结构调整和经济转型具有重要作用。风险投资通过提供企业战略咨询、关键商业网络资源、人力资源管理以及监控活动等多方面支持影响被投资企业绩效。选取2010—2018年新三板844家获得风险投资和9 415家未获得风险投资的企业，通过风险投资机构的年龄、历史IPO数量以及累计退出金额衡量投资经验，检验风险投资机构的投资经验对新三板挂牌企业绩效的影响，并利用工具变量通过二阶段最小二乘法（2SLS）解决了模型的内生性问题。实证结果表明，风险投资对企业财务绩效和成长能力均呈现显著正向影响，且风险投资机构成立年份越久，在投资经验方面越丰富，对企业绩效正向影响越显著，同时，风险投资退出业绩越好，行业内对其能力的评价越高，越有利于为企业提供附加资源支持，从而提升企业业绩。

发达国家运动员职业转型的保障政策研究

运动员保障政策不仅关系到运动员竞技成绩的提高和职业生涯的规划,还关系到竞技体育事业的可持续发展。通过对发达国家多个案例的分析论证,发现发达国家运动员保障政策对促进运动员职业转型有完备的法律体系、健全的保险种类、典型的计划和项目、系统的文化教育和职业培训体系以及广泛的社会参与5个影响要素。运动员保障政策越是满足以上5个要素,越能促进运动员职业转型成功。     

大学生专业操作能力优化教学模式的构建——以人力资源管理专业课程为例
