Beyond brainstorming: The effectiveness of computer-mediated communication for convergence and negotiation tasks

Although a considerable body of research in information systems has established that computer-mediated communication (CMC) is beneficial for brainstorming (idea generation) tasks, less is known about its effectiveness for more complex decision-making tasks. This paper reports the results of two experiments comparing the performance of face-to-face and CMC teams in decision-making tasks that move beyond brainstorming. In the first experiment, the performance of face-to-face and computer-mediated teams was compared in two tasks: one requiring participants to engage in convergent thinking and a second brainstorming task requiring divergent thinking. Consistent with predictions derived from McGrath's task circumplex model, the results of experiment one reveal that participants using computer-mediated communication perform significantly better than those interacting face-to-face on the divergent (brainstorming) task. On the convergent task, computer-mediated and face-to-face teams performed equally well; i.e., there was not a significant difference in their performance. In the second experiment, the performance of face-to-face and computer-mediated teams was again compared in two tasks: an integrative negotiation task and an idea-generation task. The results of the second experiment were similar to those of experiment one, in that computer-mediated teams significantly outperformed face-to-face teams in the idea-generation task, while computer-mediated and face-to-face teams performed equally well on the integrative negotiation task. These experiments contribute to the literature by shedding additional light on the conditions under which computer-mediated communication is as effective as, and in some cases more effective than, face-to-face interaction.     

Why computer-mediated communication improves the effectiveness of fraud brainstorming

Current auditing standards require auditors to conduct a fraud brainstorming session aimed at considering ways in which the audit client's financial statements might be fraudulently misstated. Lynch et al. (2009) document that computer-mediated fraud brainstorming is significantly more effective than face-to-face brainstorming for generating relevant fraud risks. In this study, we code and analyze process-level data from the Lynch et al. (2009) study to understand the factors contributing to the greater effectiveness of electronic fraud brainstorming. Specifically, we conduct mediation analysis to discern the degree to which equality of participation and two measures of task focus contribute to greater fraud brainstorming effectiveness when using a computer-mediated communication system compared to traditional face-to-face brainstorming. We also examine participants' perceptions of ease of system use, satisfaction with the process, and satisfaction with the outcome. Overall, the results indicate that the primary reason for the greater effectiveness of electronic fraud brainstorming is the greater degree of task focus as revealed through the length of comments made when using computer-mediated fraud brainstorming. In an absolute sense, participants using electronic brainstorming felt that their brainstorming mode was easy to use and they were satisfied with the process and outcome. The primary contribution of this study is in enhancing our understanding of precisely why computer-mediated fraud brainstorming outperforms face-to-face fraud brainstorming.     

Ethical Challenge to Businesses: The Deeper Meaning

Today, ethics has become an important dimension for businesses. Broadly, there are two lines of thought on this issue. The first one suggests that ethical issues have to be resolved through development of appropriate ethical standards at personal or organizational level. The second one emphasizes the process of developing ethical standards rather than the standards themselves. This paper argues that the latter line of thought, when taken forward, implies that ethical dimension is essentially challenging businesses to transform themselves and their people at a very fundamental level in order to evolve continuously to higher levels of perfection. The deeper significance is that in future, businesses will play a dominant role in bringing forth the human spirit, an aspect that is hitherto perceived to be in the purview of other human activity systems like the Church or family. This restructuring at the societal level is probably the most fundamental message of this age of growing interdependence.     

Profile of injury cases admitted to a tertiary level hospital in south India

Injuries now rank among the leading causes of morbidity and mortality the world over. Injuries are steadily increasing in developing countries like India. Systematic and scientific efforts in injury prevention and control are yet to begin in India. Data on injuries are very essential to plan preventive and control measures. The objective of this study is to know the profile of the injury cases admitted to M S Ramaiah hospital, Bangalore, India, using a cross-sectional study design for six months, i.e. from Oct 2008 to April 2009. The mean age of the study population was 35.3 years (SD = 15.38), 69.1% were injured in road traffic accidents (RTA), 28.7% due to falls and 2.2% due to burns. Nearly 14.4% were under the influence of alcohol. Nearly 73.6% of RTA cases were two-wheeler users, 48.5% had not followed sign boards and 56.5% had not obeyed the one-way rules, 63.5% of the two-wheeler users did not use helmets. Also, 38% of two wheelers had two pillion riders, whereas 57% of four-wheeler users had not used a seat belt. Among falls, 58% occurred at home, 49% occurred due to slippery surface. Road traffic accidents were the most common cause for injuries, in which two wheelers were most commonly involved. Strict enforcement of traffic rules and education on road safety are very essential to prevent injuries.     

Patent Enforcement, Innovation and Welfare

This paper analyzes how the Southern patent enforcement affects the Northern firm's choice of licensing, subsidiary production or exports for serving the Southern market, and the innovation rate in the North and ultimately the welfare in the South. We show that for imperfect patent enforcement, licensing contract leads to more innovation in the North relative to subsidiary or exports. When both subsidiary and exports are very costly options, no patent enforcement in the South is best for the South. However, when either subsidiary operation or exports can be organized cheaply, the Southern government chooses some positive degree of patent enforcement. We also establish that strengthening of patent enforcement in the South may lead to more licensing and less subsidiary operations or exports.     

A Time-Series Investigation of the U.S. Real Health Expenditure: Evidence from Nonlinear Unit Root Tests

This paper contributes to the literature on health expenditure studies by applying the non-linear unit root tests formulated recently by Kapetanios et al. (Journal of Econometrics 112(2):359?C79, 2003) to empirically test whether the U.S. real health expenditure time-series are non-stationary or non-linear and globally stationary during a relatively long period from 1965 to 2009. For comparison purposes, it also reports the results of a battery of traditional linear unit root tests and the Lee and Strazicich??s minimum LM unit root (Review of Economics and Statistics 85(4):1082?C1089, 2003) test for structural breaks. The empirical findings of the paper show that in the United States during the period under investigation, the real health expenditure time-series are non-stationary in levels. Policy implications of the empirical findings are discussed.
