Entropy in multiattribute problems

Concepts involving entropy have intermittently been used in consideration of multiattribute problems. This paper discusses the main approaches that have been proposed. It is argued that the analogies drawn with information theory and between weights and probabilities are to some degree unsatisfactory and a reconsideration is given. The result is a new suggestion in the spirit of Jaynes’ maximum entropy methodology, but now in two parts: ask those questions that are likely to be most discriminating (minimize entropy) but process the answers obtained conservatively (maximize entropy). In contrast to many previous methods, it is the distribution of the utilities of alternatives rather than of the weights given to attributes that is the focus of attention.

Applications of the MACBETH Approach in the Framework of an Additive Aggregation Model

In measurement theory terminology, MACBETH is an interactive approach for mapping into a real scale the various degrees to which the elements of a finite set possess a property P. The originality of MACBETH's questioning procedure is the possibility of establishing a constructive path towards cardinal measurement in both quantitative and substantive meaningful terms, avoiding the operational problems recognized as a weakness of other procedures. The use of the notion of semantic absolute judgements plays a key role here and the simplicity, interactivity and constructiveness of our approach insert it in the modern paradigms of decision aid. This article illustrates the usefulness of MACBETH as a tool to facilitate decision support, by describing its application in two real public decision situations where we acted as facilitators. Although the cases correspond to quite different decision contexts and problematics and our interventions have addressed diverse issues, they have in common the fact that we conducted both evaluation processes in the framework of an additive multicriteria aggregation procedure. In the first case MACBETH has been used to support the construction of (local) cardinal value functions, while the second illustrates how our approach can serve as a weighting procedure to determine the scaling constants of an additive aggregation model. © 1997 John Wiley & Sons, Ltd.     

Conservative speech

In this paper, I argue that an utterance can function to conserve or maintain the truth of its asserted content, what I call conservative speech. Conservative utterances can work to preserve the truth of their asserted content in two ways. In the first, directive conservatives, the utterance serves as an indirect directive for interlocutors to act in ways that serve to maintain the asserted content. In the second, constitutive conservatives, serve to partly constitute the truth conditions of the asserted content directly. Constitutive conservatives, I argue, are particularly important because they are a central tool for how social groups enforce and thereby maintain facts about group norms and values in the face of deviation. They thus have a central role to play in understanding the role of language in the abilities of social groups to create and maintain their norms and values.     

How do employees react to leaders’ unethical behavior? The role of moral disengagement

Concerns over unethical leader behavior persist in today's workplace. Although some employees continue to support their leaders after learning of their unethical actions, others do not. In this paper, we integrate social cognitive theory with social information processing theory to propose that the support employees give to leaders who act unethically hinges on their propensity to morally disengage. Specifically, we develop a conditional indirect effects model, wherein moral disengagement propensity mitigates the negative impact of unethical leader behavior on leader-directed support via employees’ perceptions of value congruence with and trust in the leader. The sum result is an improved understanding of when and why employees offer support to versus withhold support from leaders who act in ethically questionable ways.     

A multiple-objective dispersion problem

In this paper we study a multiple-objective dispersion problem from an efficient solution and value function perspective. A general fundamental theorem on non-dominance is given and a polar co-ordinate elimination heuristic is given for the case of R². Some general results are given for the existence of a linearly weighted objective function whose maximal value will give a most preferred solution, for convex or concave value functions, and a heuristic is developed for the case where these conditions do not hold.     

The value(s) of information on social network sites: The role of user personality traits

PurposeThe present research examines the relationship between personality of social network site (SNS) users and the perceived value of the information they seek. Building on the Reasoned Action Approach, personality is conceptualized as a background factor influencing people's attitude towards the information they search for on SNS.Design/methodology/approachData were collected using a face-to-face survey among Facebook users (n = 311). Personality traits were assessed based on the Big Five dimensions. Statistical analyses estimate the effects of personality traits on the various values of the information sought on SNS. A three-step procedure was followed to standardize the independent variables and create interaction variables for the moderation test.FindingsThe results support the predictions that certain personality traits (e.g., conscientiousness and extraversion), as described by the FFM framework, are related to particular facets of information value (economic value and social value respectively). The effect of personality was moderated by participants’ Facebook usage intensity. Usage intensity dampens the relationship between agreeableness and functional value of information, and strengthens the negative relationship between openness-to-experience and psychological value of information.Practical implicationsThe personality-information value relationships found can help social media practitioners and marketers shape the content and appeal of the messages communicated to their audience on SNS, and tailor marketer-customer interactions in an engaging way.Originality/valueThe present research contributes to understanding the pivotal role of personality in evaluating the information people seek on social networks. It also adds to the literature regarding FFM and social media usage by supporting the notion that the Big Five personality traits predict value aspects of information that people pursue in the course of search behavior on Facebook.Article classificationResearch paper.     

高技术的伦理风险及其应对

当代高技术的迅速崛起正日益改变世界,高技术的发展更增加了高技术伦理风险负效应的不确定性,既提供了更多的道德选择的可能性,又提出了严峻的挑战,进而使高技术的道德选择成为高技术活动主体不可回避的问题。为了在高技术的道德选择中尽可能减少高技术伦理风险负效应,就必须坚持必仁且智的价值取向、德得相通的运作方略、内圣外王的探究智慧,进而达到天人合一的澄明之境———使人-社会-自然系统协调发展。
