On the Use of Value Efficiency Analysis and Some Further Developments

The purpose of this paper is to discuss the use of Value Efficiency Analysis (VEA) in efficiency evaluation when preference information is taken into account. Value efficiency analysis is an approach, which applies the ideas developed for Multiple Objective Linear Programming (MOLP) to Data Envelopment Analysis (DEA). Preference information is given through the desirable structure of input- and output-values. The same values can be used for all units under evaluation or the values can be specific for each unit. A decision-maker can specify the input- and output-values subjectively without any support or (s)he can use a multiple criteria support system to assist him/her to find those values on the efficient frontier. The underlying assumption is that the most preferred values maximize the decision-maker's implicitly known value function in a production possibility set or a subset. The purpose of value efficiency analysis is to estimate a need to increase outputs and/or decrease inputs for reaching the indifference contour of the value function at the optimum. In this paper, we briefly review the main ideas in value efficiency analysis and discuss practical aspects related to the use of value efficiency analysis. We also consider some extensions.

A video game to supplement a hybrid principles of microeconomics course

In this article, the author describes the structure and content of a video game that she developed for a hybrid principles of microeconomics course that consists of two 50-minute lectures and a 50-minute online portion per week. The game comprises seven modules, each of which was assigned to be played during the course of the semester for the online portion of the class. The concepts covered in the game include the circular flow model, demand and supply, externalities, comparative advantage, types of market structure, sunk costs, and game theory, and the article explains in detail how the gameplay was related to these concepts. The game can be downloaded for either Windows or Mac computers, or played online at https://sites.google.com/site/gamesforecon/.     

可持续理念下的交互景观设计策略与方法研究

在信息化时代，科技高速发展，人们赖以生存的城市正在向智慧型城市转变，并不断将科学技术整合到创造性活动之中。景观作为城市系统的一部分，具有艺术形式与人文内涵，需要满足多元化的服务需求。景观的交互设计注重功能优化与美学提升，成为解决传统景观弊端的方式。从交互理念在景观设计中的应用出发，对交互景观设计策略与方法进行研究，通过对智慧城市背景下的交互景观发展优势与必要性进行论述，研究交互景观发展现状。以北京海淀Smart能量公园为例进行交互景观的设计分析，提出交互景观设计策略与方法，并对交互景观未来发展趋势进行展望。

LearnSmart,adaptive teaching,and student learning effectiveness: An empirical investigation

Facing the growing number of digital natives entering the classroom, business professors look for innovative ways to enhance the student learning experience. The authors focus on the online interactive learning tool LearnSmart (McGraw-Hill, New York, NY), and examine its impact on student learning effectiveness by testing the direct and indirect relationships among perceived competence, perceived challenge, instructors, perceived value, and satisfaction with LearnSmart. Constructionism served as the theoretical foundation for this study. About 215 students at a public university in the United States took the survey and 197 valid responses were received. Regression analysis results showed that the use of LearnSmart improved students' perceived competency, thus increasing their perceived value of using LearnSmart, as well as their satisfaction with LearnSmart. Perceived value was also found to mediate the impact of perceived competency on satisfaction with LearnSmart, and the instructor played a significant role in facilitating and improving student learning. Perceived challenge impacted student's perceived value of using LearnSmart, but it did not influence satisfaction with LearnSmart.

Nontraditional student withdrawal from undergraduate accounting programmes: a holistic perspective

A collaborative project of several Quebec universities, this study investigates nontraditional student withdrawal from undergraduate accounting programmes. A nontraditional student is older than 24, or is a commuter or a part-time student, or combines some of these characteristics. Univariate and multivariate analyses of student dropout factors were performed. A logistic regression for full-time students indicates several significant determinants of student withdrawal: returning to school after working for some time, enrolment in a non-first choice programme, dissatisfaction with programme choice and courses, and low grade point average (GPA). For part-time students, low GPA is the main explanatory factor for student withdrawal. Other factors appear to be instrumental in withdrawal decisions, such as management of external resources (time and family responsibilities) for women. The results suggest that students would benefit from university support services to acquire learning strategies that improve perseverance. Lastly, in-class learning activities that help bolster grades could decrease student withdrawal rates.     

浅析互动式教学法在《食品安全性》教学中的应用

相对于传统的单向式教学法而言,互动式教学法不失为一种很好的教学方法,它能在教学过程中充分发挥教师和学生双方的主观能动性,通过师生之间、学生与学生之间、学生与消费群体之间的对话、讨论等多种方式,以达到思想、理论和信息的交流与启发,提高学生的学习热情,注重个性发展,培养学生的综合素质。本文详细论述了互动式教学法在《食品安全性》课程教学中的应用。
