Influence of Feedback and Comment Labels on Information Sharing in a Computer Mediated Collaborative Environment

A group support system (GSS) uses a combination of networked personal computers, software, and human facilitation to improve the group decision-making process. Group support Systems are being used in the Air Force today in a variety of capacities and in particular by the Warner-Robins Air Logistics Center (WR-ALC) to assess acquisition risks. Prior GSS research has found that certain structural and social dimensions of GSS designs might influence whether optimal process improvements take place. However, the dimensions that positively influence group performance have continued to be a matter of debate. This thesis looked at several structural and social contingencies to explore possible explanations for the mixed results found in GSS research. The study examined the effect of: anonymity, identification, self-regulation, and facilitator provided feedback on user information sharing behavior, quality of the group decision, unequal participation among group members, and user attitudes with the GSS meeting. The results of the study indicated that the anonymity theory was partially supported since users in an anonymous condition provided more intellective comments than any other condition. In addition, the self-regulation theory was partially supported since users were found to have more satisfaction with the GSS meeting in this treatment

Influence of Personality Type and Anonymity on Participation in a Group Support System

A group support system (GSS) uses a combination of networked personal computers, software that collects, manipulates, and aggregates member\u27s individual input, and human facilitation to improve the group decision-making process. A GSS has been promoted as a means of improving the quantity and quality of ideas within a decision-making meeting. Research into GSS has focused on the benefits of providing anonymity to improve participation. Anonymity in a GSS meeting has been offered as a means to improve participation, which in turn improves decision quality. To date this has not been proven through research. In fact, there is conflicting evidence as to what the actual effects of anonymity are. Research in social psychology provides a possible explanation for the conflicting results of the effects of anonymity. An individual\u27s personality characteristics can affect how they participate in a decision-making meeting. The study examined how an individual\u27s personality type and varying degrees of anonymity influence individual participation in a GSS meeting. The results of the study suggest personality characteristics have a significant impact on participation within a GSS supported meeting. Further, the results suggest personality and its interaction with anonymity has a positive effect on participation for some individuals, but not all. Consistent with most prior GSS studies, the results suggest anonymity does have a positive effect; however, this effect was significant only for certain personality traits

The Temporal Dimension of Electronic Meetings: A Study of Synchronous and Asynchronous Idea Generation

Electronic meeting systems can increase the efficiency and effectiveness of group discussions, but relatively little research has investigated use of the technology in asynchronous environments. In this study, five groups of 10 students participated in synchronous legislative sessions and five groups of 10 met in asynchronous settings. Results showed that there were no differences in meeting process satisfaction, production blocking, evaluation apprehension, and total and relevant comments generated, but synchronous groups believed there was more participation and were more satisfied with the comments. Although there could be less feeling of social presence, use of asynchronous, distributed meetings might become more prevalent as groups seek to reduce travel

Microfinance games

Microfinance has been heralded as an effective way to address imperfections in credit markets. But from a theoretical perspective, the success of microfinance contracts has puzzling elements. In particular, the group-based mechanisms often employed are vulnerable to free-riding and collusion, although they can also reduce moral hazard and improve selection. The authors created an experimental economics laboratory in a large urban market in Lima, Peru and over seven months conducted 11 different games that allow them to unpack microfinance mechanisms in a systematic way. They find that risk-taking broadly conforms to predicted patterns, but that behavior is safer than optimal. The results help to explain why pioneering microfinance institutions have been moving away from group-based contracts.Banks&Banking Reform,Insurance&Risk Mitigation,Financial Intermediation,Social Accountability,Civic Participation and Corporate Governance

In particular, the group-based mechanisms often employed are vulnerable to free-riding and collusion, although they can also reduce moral hazard and improve selection. We created an experimental economics laboratory in a large urban market in Lima, Peru and over seven months conducted eleven different games that allow us to unpack microfinance mechanisms in a systematic way. We find that risk-taking broadly conforms to predicted patterns, but that behavior is safer than optimal.

Socio-Psychological Aspects of Group Processes

The original working paper had no abstract. The purpose of the working paper was to document previous research undertaken in group research (broadly) from the socio-psychological perspective. Some of this directly related to work on GSS, some of it was antecedent to that research

PROCESS SUPPORT FOR THE OPTION GENERATION PHASE IN WIN-WIN NEGOTIATIONS: COMPARISON OF THREE COMMUNICATION MODES

Analytically oriented Negotiation Support Systems have been studied and developed for decades, but they have not become widely adopted by negotiation practitioners. Along with the phenomenal growth of e-commerce, a need has arisen for information systems that support the parties’ “soft” negotiation processes and communications in addition to the “hard” quest for a mathematically optimal solution. In this study, we report an experiment about applying three different communication modes in integrative win-win negotiations following the principled negotiation tactics. We focus on integrative negotiation’s dialoguing phase where the parties share information, brainstorm options together, and establish an appropriate atmosphere. We compare computer-supported same-time same-place negotiations aided by group support systems (GSS) - either anonymously or non-anonymously - with the control treatment group that uses verbal communication backed up with flipcharts and Post-it notes. Due to the recent social media revolution, the role of anonymity might have changed from the GSS research results obtained decades ago. Our goal is to find out possible differences in the negotiation outcomes: meeting satisfaction and productivity. We discovered that all three modes worked well when used together with a carefully structured and facilitated process, although the number of unique ideas generated was significantly higher in the computer-supported groups

Electronic Facilitation of Large Meetings

Many meetings involve large groups exchanging oral comments in a face-to-face environment, yet few studies have investigated how electronic facilitation can benefit these discussions. In this paper, we studied two large oral meetings (group sizes of 38 and 37) and two computer-based meetings (group sizes 33 and 35). Results show that, as in smaller groups, members of electronic meetings experience less production blocking and evaluation apprehension and generate more total comments, relevant comments, and words per comment. However, contradicting prior research, participants in the oral meetings were more satisfied with the process
