An imprecise goal programming approach for modeling design team's preferences in quality function deployment planning process

The Quality Function Deployment (QFD) is an approach that facilitates designing product by analyzing and projecting the Customer's Needs (CNs) in the Engineering Characteristics (ECs) of a product. The aim of QFD planning process is to determine the target levels for ECs of a product that achieve high level of overall customers' satisfaction. However, integrating design team's preferences in this preliminary stage of product design could make the design more realistic and could also avoid unfeasibility in posterior phases of the product development processes. Moreover, this process is performed within an imprecise environment, and more than one factor must be taken into account in determining targets levels of ECs; especially, the limited resources and increased market competition. This paper presents an imprecise goal programming approach to determine the best aspiration levels of ECs in QFD planning process. Based on benchmarking data of ECs, the concept of satisfaction functions will be utilized to integrate explicitly the design team's preferences and incorporate the competitive analysis of target market into the modelling and solution processes. In addition, the relationships linking CNs and ECs and the ECs to each other are integrated by functional relationships. The proposed approach will be illustrated through an example of product development of an emulsification dynamite packing machine. Copyright © 2011 John Wiley & Sons, Ltd.

工作重塑：获得意义性工作与个人成长的新途径

工作重塑是组织行为学中新近出现的一个热点话题,是指员工通过自己对工作进行重新建构来形塑自己的工作认同以及工作角色,其核心目的就是员工对他们的工作进行再设计以获得较高的工作意义感、工作投入以及工作满意度等,进而快乐地工作。在系统梳理有关工作重塑的理论与实证研究文献的基础上,从工作重塑概念的解读、工作重塑的方式与方法、工作重塑的预测因素、工作重塑对个体与组织的影响以及工作重塑的培养策略等方面进行了综述,以便人们更深入地体会其丰富的理论内涵和实践价值;最后,该文指出未来工作重塑的研究应继续注重理论建构的丰富与完善、关注工作重塑的个体与群体差异性以及深化工作重塑与组织之间的关系研究。     

What is A Philosophical Question?

There are many ways of understanding the nature of philosophical questions. One may consider their morphology, semantics, relevance, or scope. This article introduces a different approach, based on the kind of informational resources required to answer them. The result is a definition of philosophical questions as questions whose answers are in principle open to informed, rational, and honest disagreement, ultimate but not absolute, closed under further questioning, possibly constrained by empirical and logico‐mathematical resources, but requiring noetic resources to be answered. The article concludes with a discussion of some of the consequences of this definition for a conception of philosophy as the study (or “science”) of open questions, which uses conceptual design to analyse and answer them.     

Improving oral reading fluency with a peer-mediated intervention

This study examined the effects of an experimentally derived, peer-delivered reading intervention on the oral reading fluency of a first-grade student who had been referred for poor reading fluency. Same-grade peers were trained to lead the target student through a structured intervention protocol based on the results of a brief experimental analysis. Results indicated that reading improvements were obtained and are discussed in terms of selecting efficient interventions for use by peers.     

Rethinking technology, revitalizing ethics: Overcoming barriers to ethical design

This paper explores the role of ethics in design. Traditionally, ethical questions have been seen as marginal issues in the design of technology. Part of the reason for this stems from the widely held notion of technology being “out of control.” This notion is a barrier to what I call “ethical design” because it implies that ethics has no role to play in the development of technology. This view, however, is challenged by recent work in the field of Science and Technology Studies (STS). Looking into the dynamics of technological change, STS scholars argue that human choices are present at every stage of a technology’s development and, furthermore, that human values are reflected in the very design of artifacts. This alternative view suggests that ethics can and should be included in the design process. Drawing on examples from the privacy arena. I point to some of the potential advantages of addressing ethical concerns early on in the design of a technology. I conclude with some general strategies for bringing ethics back into design. A version of this paper was presented at ETHICOMP98, the Fourth International Conference on Ethical Issues of Information Technology, March 25–27, 1998, Erasmus University, the Netherlands. Patrick Feng is a Ph.D. student in the Science and Technology Studies Department at Rensselaer. His research focuses on the development of technical standards that are designed to address social values such as privacy and trust.     

Psychophysical design influences frequency discrimination performance in young children

We investigated how different psychophysical procedures affect frequency discrimination performance in children. Four studies used a design in which listeners heard two tone pairs and had to identify whether the first or second pair contained a higher frequency target tone. Thresholds for 6- and 7-year-olds were higher than those for 8- and 9-year-olds and adults. Two manipulations led to lower (better) thresholds in young children: (a) moving the standard comparison tone before the target tone and (b) using three target comparison tone pairs. It is suggested that young children benefit from designs that help cue them to when they need to attend to a target tone. The two-interval, forced-choice procedure that is widely used in studies of developmental disorders led to variable performance even in adults and did not give a realistic picture of the perceptual capabilities of children under 8 years of age.
