Multicriteria Portfolio Modeling for the Development of Shared Action Agendas

Organizations and collaborative networks set strategic directions by building agendas of action topics that will be implemented subject to limited resources and other constraints. The development of such agendas typically involves several decision makers and possibly other stakeholders who may have divergent views about how the topics contribute to multiple objectives. The processes of developing these agendas can be supported by methods of multicriteria decision analysis which allow the group members’ preferences to be systematically and transparently synthesized. In this paper, we extend methods of portfolio decision analysis with the aim of guiding the development of agendas in the presence of possibly incomplete information about the group members’ preferences and the impacts of the proposed topics. Specifically, we define performance measures that convey (i) what topics are favored by individual group members and (ii) how acceptable alternative portfolios of topic agendas are to the whole group. The methods are illustrated with data from a real case study for the development of a national research agenda on wood products in Finland.     

Conflicting Objectives within the Board: Evidence from Overlapping Audit and Compensation Committee Members

The board of directors is an elite group that faces multifaceted tasks. The board needs to implement decisions on a wide variety of subject matter. These decisions are often delegated to specialized sub-committees within the board. The different objectives of each sub-committee can result in conflicting interests leading to decisions that are sub-optimal. For example, at times, the objectives of the compensation and the audit committee are not aligned. The objective of compensation committees is to grant CEOs compensation packages reflective of their performance. Yet, these compensation packages might contain incentives that could motivate CEOs to influence the financial reporting process in order to reflect better performance, increasing the risk of poor quality financials. In contrast, the objective of audit committees is to oversee the quality of the financial reports and the process that leads to them. Therefore, they would favor compensation packages that reduce the risk of earnings manipulation. We examine public companies that have overlapping compensation and audit committee members and find a higher proportion of CEO incentive compensation in companies with less overlap among audit and compensation committee members. These results suggest that separating the members within these committees might contribute to the effectiveness of board decisions.

A Study Towards Improving Web-Based Collaboration Through Availability of Group Awareness Information

Group awareness can be broadly defined as consciousness and information of various aspects of the group and its members. It also refers to information received by members of a group about the other group members, about mutually employed objects, and about current group processes, in order to efficiently carry out certain tasks. The group awareness information presented in this paper is designed to capture group member activities and their behaviors in web-based collaborative work. It consists of activity, availability, and commitment/disposition information. The first two parameters appear as a visual display representing cumulative data and changes accordingly when the group begins working together. The last parameter is captured during group work and is summarized at the end of the group work task. This paper reports on the results of a study in a controlled experiment that examined group performance on a given task in a web-based group decision support system with and without group awareness information. In particular, the study examined how group awareness information impacts the quality of the work effort and a given task, group decision making by members in the same group and different groups, the communications among group members during the completion of an online collaborative authoring task, the cohesiveness among group members, and the commitment/disposition of engagement of each member of the work group.     

A Comparison of Full Profile and Hierarchical Information Integration Conjoint Methods to Modeling Group Preferences

This paper presents a comparative test of full profile (FP), original hierarchical information integration (HII-O), and integrated hierarchical information integration (HII-I) conjoint methods for modeling group preferences. It is hypothesized that in settings where groups need to decide about complex multi-attribute alternatives, HII-O will predict holdout profiles better than FP, and that HII-I will perform better than HII-O. The predictive ability of the three methods is tested for the case of housing preferences of housing co-ops, which are groups consisting of three to five people who jointly own a house. The results confirm that HII-I outperforms the other two methods and further suggest that FP and HII-O perform equally well. In addition, two variations of HII-I are developed. One of these provides independent estimates of the relative influence of group members on the decision outcomes, however at the expense of requiring larger designs. The two HII-I variations are also tested and found to be equivalent in predictive ability.

The Impact of Ethical Climate on Project Status Misreporting

Without complete and accurate status information, a project manager’s ability to monitor progress, allocate resources effectively, and detect and respond to problems is greatly diminished, and this can lead to impaired project performance. Many different factors can contribute to intentional misreporting of status information by project members to the project manager. In this study, the impact of organizational ethical climate was assessed through the analysis of responses from 228 project members drawn from a variety of ongoing information systems projects. Our results revealed that project members who perceived their organization to be one in which rules are followed strictly tended to misreport less, while those operating in an environment dominated by personal self-interest tended to misreport more. Somewhat surprisingly, the existence of a caring, team-spirited environment did not appear to have an impact on misreporting behaviors. Implications for researchers and project managers are discussed.     

Exposure to workplace bullying and negative gossip behaviors: Buffering roles of personal and contextual resources

This study adds to business ethics research by investigating how employees' exposure to workplace bullying might spur their negative gossip behaviors, as well as how this effect might be buffered by their access to two personal resources (religiosity and innovation propensity) and two contextual resources (work meaningfulness and trust in top management). Survey data collected among Canadian-based employees who work in the religious sector reveal that workplace bullying increases the likelihood that they spread negative rumors about other organizational members, but this effect is weaker when employees (1) can draw from their religious faith, (2) are motivated to generate innovative ideas, (3) derive meaning from their work, and (4) have confidence in the trustworthiness of top management. For management scholars and practitioners, this study thus pinpoints different resources that diminish the risk that workplace bullying infuses work environments with even more negative energy, as might occur if bullying spills over into additional, negative gossip behaviors.     

The Effects of Integrating Cognitive Feedback and Multi-attribute Utility-Based Multicriteria Decision-Making Methods in GDSS

Cognitive conflicts arise within groups because the members of a group view a problem from different perspectives, even when they have similar interests in achieving a goal. Disagreement within a group may occur due to: (a) differing judgment policies among the members, (b) inconsistency by any member in using a judgment policy, (c) group process losses that prevent group members from understanding each other better, or (d) limited processing capability which may prevent group members from processing all information effectively. Disagreement is especially likely when policies, processes, or information are conflicting in nature.A level 2 GDSS to aid judging in cognitive conflict tasks is presented that combines cognitive feedback and Multi-attribute utility (MAU) theory based multicriteria decision-making techniques with the communication structure and activity-structuring capabilities of a level 1 GDSS. Though cognitive feedback and MAU methods have been used separately to help groups resolve cognitive conflicts, never before have the two decision aids been used together in a computer-based collaborative system.The contributory effects of the components of this GDSS design were empirically tested in a laboratory setting. Three treatments: an unaided face-to-face meeting, a level 1 GDSS supported meeting, and a level 2 GDSS supported meeting were compared in a repeated measures experimental design.Results largely supported the proposed research hypotheses. Some specific findings include: (1) the level 2 GDSS reduced disagreement between group members and improved consistency of judgments better than the other meeting environments did; (2) there was no significant difference in the reduction of disagreement between the level 1 GDSS and face-to-face meetings; and (3) while there was no difference in improvement of consistency of individual judgments between the face-to-face and level 1 GDSS supported meetings, group judgments made in face-to-face meetings were more consistent.     

Performance measurement and metric manipulation in the public sector

This paper explores the circumstances that influence whether managers in the public services manipulate the measurement information that is used to assess performance; and if they do, what level of deception they might use. The realistic evaluation approach is adopted. A Delphi survey and the collection of critical incidents through interviews are used to identify possible configurations of contexts–mechanisms–outcomes that provide possible explanations of information manipulation. A number of these configurations are discussed. In a later stage of the project these configurations will be further tested through another Delphi survey, with the intention of developing proposals for improved governance of performance measurement systems in the public services.     

Performance in Product versus Service Supplier Relationships

ABSTRACT

Today's rapidly changing and competitive marketplace has forced channel members to devote increased attention and resources to providing consumers with a seamless delivery of products and services. This seamless delivery occurs through social integrative relationships between channel members, supported by the application of information technology. Achieving integration is a difficult task that may vary based on whether a product or a service is involved. This paper proposes that manufacturer integrative relationships with product suppliers may develop with lower levels of seamless delivery when compared to manufacturer integrative relationships with service suppliers. Further, the paper discusses how the application of information technology may impact manufacturer-supplier relationships and performance.     

Revenue sharing in network utility maximization problems

Alliances arise in a wide variety of domains, when a group of countries, political parties, people or other entities agree to work together because of shared interests or aims. They make sense, if the output obtained is somehow better than the outcome of acting individually. Revenue or cost sharing is key when determining if individuals are better off by contributing to an alliance or not. In our alliance each member owns a unique resource –or set of resources–, which is given to the alliance. The alliance sells services, which are supported thanks to one or a set of these resources. We focus on alliances that sell services in such a way that the total revenue of the alliance is maximized. We show that this kind of problems can be modeled through a Network Utility Maximization problem. We subsequently explore the problem of revenue sharing among the members of the alliance. Such a problem is a complex one since the interests of all participants must be ensured and correct incentives must be provided. We formally formulate the members’ interests through a set of properties the revenue sharing method should verify. We then discuss the existing methods for revenue sharing and conclude that none of them verifies the needed properties for the case of a revenue maximizing alliance. We finally propose a revenue sharing method based on projecting the contributions of each member of the alliance into an economic stable set. Through an exhaustive simulative study we conclude that our method provides, in addition to economic stability, fairness among members and the right incentives to them. Through our analysis Network Service Provider alliances, which sell quality-assured data transport services, are considered as an application example.     

Awareness changes placebo effects for feeling relaxed,but not for liking

Information and communication of beliefs can influence effectiveness and liking of food products. This study is the first to investigate how two positive states, activation and relaxation, can be associated with a product through communication, how this influences liking, and how manipulation awareness influences both liking and the association between positive states and the product. Three groups of participants received an unfamiliar herbal infusion. Group 1 was told that the herbal infusion would have activating properties, group 2 was told that it would be relaxing, and group 3 was given no information. During an 11-day home-consumption phase, 148 participants filled in a diary, detailing consumption and feelings of relaxation. On day 12, implicit and explicit measures of relaxation, liking, and manipulation awareness were taken after consumption. Participants in the relaxed condition felt significantly more relaxed than participants in the active and the control condition, but only if they were unaware of the experimental manipulation. Independently of awareness, participants liked the tea better in both the activating and the relaxing than in the control condition. Results show that a positive state can be connected with a product without employing active ingredients, and that liking increases as a consequence of this connection. Results also show a trend that manipulation awareness influences the effect on positive state, but not on liking.     

Anonymous market and group ties in international trade

History provides many examples of cohesive groups dispersed over several countries who exploit the ties between their members to gain entry into foreign markets. The phenomenon is well-established empirically and noteworthy because it suggests the importance of informational barriers in international transactions. We present a simple model where output is produced through a joint venture, and agents have complete information domestically but are unable to judge the quality of their match abroad. A minority of individuals, otherwise identical to all others, can exploit complete information in international matches between group members, if they so choose. Group ties increase aggregate trade and income, but hurt the anonymous market because they deprive it disproportionately of the group’s more productive members.

Using and Influence Level of Information to Explain the Non-consensus Process Loss

Much of the Group Support System (GSS) literature comparing GSS groups with manual groups has produced contrarian results. One of the more confusing is that GSS groups have a higher level of non-consensus than manual groups. Lack of consensus in GSS groups is considered to be a negative aspect of GSS. This paper argues that low levels of consensus are not necessarily harmful and should be expected given the assumptions about GSSs. This study uses an alternate measure to compare face-to-face groups with GSS groups; an influence level of information. Experimental results using an influence level of information show no difference between face-to-face group members and GSS group members. We discuss these implications, as well as additional directions for further consensus research.     

Aggregation and Disaggregation of Preferences for Collective Decision-Making

Group decisions are of longstanding interest to researchers from a wide spectrum of disciplines. Group Decision Support Systems (GDSS) can play a vital role in situations where multiple persons are involved, each having their own private perceptions of the context and the decision problem to be tackled. In such an environment the conflict between the members of the planning group is not an unusual situation. Multiple criteria decision aid (MCDA) methods may be a useful tool in coping with such interpersonal conflicts where the aim is to achieve consensus between the group members. This paper combines two well-known multicriteria methods, based on the notion of aggregation of preferences, in order to construct a consensus seeking methodology for collective decision-making.
