第三方回收闭环供应链协调应对突发事件研究

本文以一个制造商、一个零售商和一个第三方回收商组成的闭环供应链系统为研究对象,分析了闭环供应链中存在的"双边际效应"问题,并通过收益费用共享契约解决上述问题,使闭环供应链实现协调。此外,本文分析了突发事件引起闭环供应链中最大市场需求规模发生扰动时,原收益费用共享契约下闭环供应链的协调会被打破这一问题,进而对收益费用共享契约加以改进,使之适用于协调突发事件发生前与发生后的闭环供应链系统。

Probing the allocation of attention in implicit (motor) learning

Abstract

We investigated the attention demands associated with implicit and explicit (motor) learning and performance using a probe reaction time paradigm. Two groups of participants learned a golf putting task over eight blocks of 50 trials performed from different distances. One group (errorless learning) began putting from the shortest distance (25 cm) and moved progressively back to the furthest distance (200 cm). A second group (errorful learning) began putting from the furthest distance (200 cm) and moved progressively closer (25 cm). Retention tests were used to assess learning in the two conditions, followed by transfer tests in which participants used either an unusual putter or a very unusual putter. Transfer to the unusual putters had an equivalent effect on the performance of both errorless and errorful learners, but probe reaction times were unaffected in the errorless learners, suggesting that execution of their movements was associated with reduced attention demands. Reducing errors during initial learning trials may encourage an implicit mode of learning and lower the demand for cognitive resources in subsequent performance.     

The effect of the demand control and effort reward imbalance models on the academic burnout of Korean adolescents

The purpose of this study was to examine the effects of the Demand Control Model (DCM) and the Effort Reward Imbalance Model (ERIM) on academic burnout for Korean students. Specifically, this study identified the effects of the predictor variables based on DCM and ERIM (i.e., demand, control, effort, reward, Demand Control Ratio, Effort Reward Ratio) on academic burnout. Participants were 1,530 elementary, middle, and high school students and multivariate multiple regression analysis was used. Results indicated that the variables of ERIM (i.e., effort, reward, Effort Reward Ratio) were more influential predictors than the variables of the DCM (i.e., demand, control, Demand Control Ratio). Implications and limitations are discussed.     

品牌信用度持久性及品牌策略研究

本文应用品牌经济学理论,从品牌效用入手,分析品牌的物质利益和情感利益两个要素,认为品牌效用由物质效用和情感效用构成,并从物质利益和情感利益随时间而减弱的特点,推导品牌信用度随时间是趋于下降的,因此,需要在这一过程中实施正确的品牌策略。在此基础上,引入需求品牌策略弹性概念,论证了不同品牌策略效果:在产品消费末期实施品牌策略效果要好于初期;新品类实施品牌策略效果要好于老品类。最后,通过构建品牌信用度和品牌策略动态模型,进一步验证上述推论,并提出品牌实现动态利润最大化的条件,即品牌信用度边际成本等于品牌策略引起的未来时期品牌边际利润贴现值之和。
