接受理论与提高思想政治课有效性研究

接受理论在思想政治课教学中已有的研究成果,并不能明显改善当前思想政治课的效率、效果和效益,其根本原因在于未能根据思想政治课的特点对接受理论进行完善。因此,从思想政治课有效性的角度出发,对接受理论进行重新认识,并在教学模式上进行创新具有重要的现实意义。     

基于批判性思维的大学英语课堂教学过程控制研究

基于传统的大学英语教学存在重知识传授,轻思维能力培养的倾向,学生课堂参与度低,英语教学费时低效.在此利用批判性思维设计课堂教学,将课堂教学过程看作一个系统,分析教师、学生和教学过程在本系统中的关系和地位.作为主体的教师需要通过有效的教学过程设计,借助教学过程中的新手段、方法和评价机制,促进作为客体的学生实现主动反馈,实现主客体间的有效信息交互和主体驱动下的客体主动反馈,最终实现提高课堂教学质量的目的.     

创新理论框架下欧盟可再生能源发展路径研究

气候与环境问题已经成为国际问题领域关注的焦点,而缓解温室气体排放、环境污染最重要的途径就是大力发展可再生能源,这已经成为全球性共识。作为新能源发展的领头羊,欧盟在2020年前计划达到可再生能源占总体能源20%比例的目标,其中创新模式在发展路径中的应用是关键。本文通过创新理论的三个层次施动者,创新工具以及社会反馈对欧盟的可再生能源发展路径进行剖析。     

In Praise of Feedback: An Effective Intervention for College Students Who Are Heavy Drinkers

Abstract

The efficacy of brief motivational feedback to reduce drinking among college students has been reported by several researchers. As an extension of this theoretical and applied framework, the author tested the use of mailed feedback to influence the drinking behavior of students self-identified as moderate-to-heavy drinkers in two randomized trials. A 6-week follow-up of the efforts suggested the efficacy of the feedback intervention at reducing alcohol consumption. The feedback mechanism used in the studies is described in detail and possible reasons for its efficacy are explored. In light of the cost-effective nature of this intervention, it may warrant a place in larger campus prevention programs.     

Endogenous Liquidity and Defaultable Bonds

This paper studies the interaction between default and liquidity for corporate bonds that are traded in an over‐the‐counter secondary market with search frictions. Bargaining with dealers determines a bond's endogenous liquidity, which depends on both the firm fundamental and the time‐to‐maturity of the bond. Corporate default decisions interact with the endogenous secondary market liquidity via the rollover channel. A default‐liquidity loop arises: Assuming a relative illiquid secondary bond market in default, earlier endogenous default worsens a bond's secondary market liquidity, which amplifies equity holders' rollover losses, which in turn leads to earlier endogenous default. Besides characterizing in closed form the full interdependence between liquidity and default for credit spreads, our calibrated model can jointly match empirically observed credit spreads and liquidity measures of bonds across different rating classes.     

Replacing Voice Input With Technology That Provided Immediate Visual and Audio Feedback to Reduce Employee Errors

In this report from the field at two auto parts distribution centers, order selectors picked auto accessories (e.g., fuses, oil caps, tool kits) into industrial plastic totes as part of store orders. Accurately identifying all store order totes via the license plate number was a prerequisite for the warehouse management system (WMS) to track each tote to the correct sorting lane, the correct shipping door, the correct route, the correct store, and to invoice the store. Using voice technology, the order selector uttered the license plate number; however, in the event the utterance did not match the license plate number affixed to the lid of the tote, the tote was routed to a “penalty” area of the sorting lanes as a misidentified tote. Each misidentified tote cost the company approximately $500 in lost labor and lost sales. Replacing the utterance of the order selector with a scanning stylus that provided both a “good read” light indicator and a “good read” auditory beep informed the selector that the license plate had been scanned and reliably decreased the number of misidentified totes. The role of the organizational behavior management (OBM) practitioner in industrial settings in designing interventions that increase accuracy and productivity was examined.     

The Effects of Task Clarification and Group Graphic Feedback on Early Punch-In Times

Task clarification in the form of workplace policy guidelines coupled with weekly graphic feedback of group punch-in times on the staff clock were presented to waitstaff, cooks, cash register clerks, dishwashers, buffet attendants, and hourly assistant managers in a restaurant sub-franchise. Clocking in early dropped from 130 min during baseline to 62 min per week during intervention. A 1-week return to baseline resulted in 189 min of clocking in early by restaurant personnel. The use of task clarification and group feedback reduced company expenses without reductions in job satisfaction or increased stress.     

Considerations in Feedback Delivery: The Role of Accuracy and Type of Evaluation

Performance feedback remains a commonly implemented and successful intervention within organizational behavior management, but a comprehensive understanding of the components that influence the effectiveness of feedback tends to be lacking. The present study sought to contribute by analyzing the variables of accuracy (contingent on or independent of performance) and evaluation type (supportive or critical judgments) on performance using a simulated work environment. A total of 75 undergraduate students were randomly assigned to 1 of 4 experimental conditions: (a) contingent and supportive feedback, (b) contingent and critical feedback, (c) independent and supportive feedback, or (d) independent and critical feedback. Outcomes suggested that contingent feedback improved performance relative to independent feedback, however, no differences were found between supportive and critical types of feedback. The need for additional research into the functional and formal elements of effective feedback is also discussed.
