Dysfunctional executive behavior: What can organizations do?

Much has been made of dysfunctional executive behavior in recent years. As such, the purpose of this article is to assist organizations in the design of executive work. To better construct a work environment that diminishes self-serving and unethical behavior, we propose that organizations structure an executive's work around three factors: the accountability environment, managerial discretion, and relationship composition. These factors are used to describe how organizations can better design executives’ work so as to promote more desirable executive behavior. We describe how these factors should be calibrated, as well as how they affect each other.     

Supporting the Evolution of Teams With Transactions: A Design Architecture for Organizational Memory Systems

In this article, we present a general-purpose architecture and design metaphor for supporting the evolution of teams. The architecture is based on the premise that the role of organizational memory involves active support for accessing the relations and content of past, present, and future information-based artifacts of collaborative work. The evolutionary work support role and structure of memory are outlined and contrasted with existing research. A set of design requirements for supporting memory are presented and the concept of a collaborative transaction is introduced. The collaborative transaction concept is the basis for the TeamBox architecture and prototype, which shows that it is possible to generically support the evolutionary needs of collaborative work. The article ends with a discussion of limitations and future research issues.     

Dual Information Systems: Supporting Organizational Working and Learning by Making Organizational Memory Transparent

The conceptual design of most computer-based information systems reflects a dualism of technology. During the development phase, part of the work-domain-related knowledge is formalized and encoded in the software, making it difficult for users to reflect on and use this knowledge. This design--use dualism contributes to the deterioration of the interpretive flexibility of information systems. In this article, we outline an information systems architecture called Dual Information Systems (DIS) that incorporates the concepts of an organizational memory information system (OMIS) in a broader framework. DIS help bridge the design--use dualism by providing organizations with a set of services that enable and reinforce both effective, institutionalized working and the questioning and (re)construction of computer-supported work routines. DIS have a 4-layered conceptual structure: (a) people draw on the business layer to work and learn; (b) people use the breakdown layer to handle unexpected break-downs; (c) self-organizing project teams use the project layer to create innovative work and information system (re)designs; and (d) the knowledge sharing server acts as an OMIS by storing these redesigns and making them organizationally available to facilitate working and learning as well as subsequent redesign efforts. We outline the theoretical background, conceptual structure, and generic services of DIS. We elaborate on the services and the conceptual design of the business and breakdown layers of DIS. The services help people work effectively and develop competence needed to handle breakdowns and participate in the redesign project teams. The conceptual design extends the hyperknowledge framework of Chang et al [1]. Finally, we demonstrate the conceptual design and services in a financial services organization with the help of the ReDIS prototype.     

Proposal for Components of Method Design Theories

Gregor and Jones have proposed components for design theories, building on theory concepts from behavioural sciences and prior publications. Their design theory structure addresses IT artefacts in general, not specific to any type, such as constructs, models, methods or instantiations. Their work is an important contribution to the academic discussion of design theories. The authors are building on this and believe that specialised design theory structures for different types of artefacts further increases utility, usability and acceptance of the components for both academia and practise. They have analysed each of the components published by Gregor and Jones and proposed refinements specific to method design artefacts wherever applicable. For each component, they derive evaluation criteria and present examples of method publications fulfilling the criteria. They argue that by presenting method design theories according to this structure the contribution of method design artefacts to the body of knowledge will increase.     

Interdependencies between Marketing and Public Relations Disciplines as Correlates of Communication Organisation

The academic literature on corporate and marketing communication organisation is characterized by a comparatively large amount of conceptual work, with little detailed empirical analysis to support the theoretical perspectives offered. Following an established line of inquiry in organisational research; an information-processing perspective on organisational structure and design, the article develops and tests the hypothesis that interdependencies between marketing and public relations disciplines are correlated with choices for organisational arrangements. The findings of an exploratory analysis of organisations in the UK suggest, however, that in the majority of cases there is a lack of fit between information processing requirements brought about by the interdependencies between the marketing and public relations disciplines and the information processing capacity accompanying the actual design choices and organisational arrangements made. The practical implications of these findings for practitioners are discussed, and recommendations for further research are made.     

Ethically Questionable Behavior in Sales Representatives – An Example from the Taiwanese Pharmaceutical Industry

Recent corporate disgraces and corruption have heightened concerns about ethically questionable behavior in business. The construct of ethically questionable behavior is an under-portrayed area of management field research, and deserves further studying, especially in sales positions. This study uses four variables from the human resource management field to explain the ethically questionable behavior of sales representatives in the pharmaceutical industry. These variables include frame pattern, commission structure, behavior control type, and marketing norm perceptions. This work uses a 2*2*2*2 subject experimental design, and 328 fully completed questionnaires for logistic regression analysis. Results suggest that a medical representative in a loss frame (compared with a gain frame), in a high commission structure (compared with a low commission structure), in loose behavior control (compared with strict behavior control), and in a low perception of marketing norm (compared with a high perception of marketing norm), is more likely affected by heuristic biases and make an ethically questionable choice.     

具有无损吸收功率因数校正变换器的研究

提出了一种无源无损缓冲升压功率因数校正（PFC）电路,与传统的PFC电路相比具有许多的优势。首先,主开关上不引入额外的电压和电流应力;其次,为主开关管的软开关提供了很宽的输入和负载变化范围;第三,限制了主开关管上来自反向恢复输出二极管的导通电流。本文详细分析了无源无损缓冲升压功率因数校正（PFC）电路的工作过程,对没有加无源无损缓冲结构和加了无源无损结构之后的两者电路性能特点进行了比较研究。最后,在理论分析的基础上研制一台250W的实验样机,实验结果表明,本文提出的缓冲结构在设计操作范围内可以有效地减少能量的损耗,提高工作效率。

The Effectiveness of Corporate Ethics On-site Visits for Teaching Business Ethics

This paper describes and reports the evaluation ofusing corporate ethics field site visits in a businessethics course. The dilemma of how to design ameaningful business ethics course has been the subjectof debate for business school ethics instructors andis reviewed here. The structure of the site visitsand how student work is evaluated is presented. Twostudies evaluating the field site visits were done. The first study utilized qualitative methods toevaluate students' reactions as well as comments fromthe corporate ethics officers who host the visits. The second study utilized a pretest-posttest surveydesign to quantitatively evaluate student reactions tothe site visits. Results showed a statisticallysignificant, positive change in students' attitudes. This effect was moderated by gender, showing astronger positive effect for females than for males.
