Estimating ordered quantiles of two exponential populations with a common minimum guarantee time

The problem of estimating ordered quantiles of two exponential populations is considered, assuming equality of location parameters (minimum guarantee times), using the quadratic loss function. Under order restrictions, we propose new estimators which are the isotonized version of the MLEs, call it, restricted MLE. A sufficient condition for improving equivariant estimators is derived under order restrictions on the quantiles. Consequently, estimators improving upon the old estimators have been derived. A detailed numerical study has been done to evaluate the performance of proposed estimators using the Monte-Carlo simulation method and recommendations have been made for the use of the estimators.     

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.

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

高校人才培养与企业实际需求存在匹配度较低的问题,因而有必要构建新的大学生专业操作能力优化教学模式.新的教学模式涵盖目标描述、目标支撑、流程管理、经验教训、工具与表单五个方面.它可以让学生的学习从抽象到具体,从理论到实践,从宏观到微观,从被动接受到主动思考,达到对该模块更深刻的学习、掌握与运用,从而更加适应企业与社会的需求.     

Chronic Child Abuse: The Characteristics and Careers of Children Caught in the Child Protection System

The introduction of the Quality Protects initiative in Englandand the focus on performance management has challenged socialservices departments to examine the systems, processes and outcomesfor children who have their name on a child protection register.Research indicates that approximately one-quarter of the situationsin which children are registered could be described as chronic—thatis, they remain on the child protection register for significantperiods of time, experience more than one period of registrationor suffer a further incident of significant harm whilst subjectto a child protection plan. In this article, the findings froma research study conducted into this group of vulnerable childrenare reported, focusing on the characteristics of the childrenand their families, and their careers in the child protectionsystem. The paper concludes with observations about the weakconceptualization of performance management and the need torecognize the complexity of the factors that influence children’scareers in the child protection system.
