Item Alternative scenarios to the “banner” years: A test of alternative formats to Web banner ads(2008-02) Taylor, Nolan J.; Loiacano, Eleanor T.; Watson, Richard T.A test of alternative formats to Web banner ads.Item The Impact of Public Grid Computing Portfolio Composition on Adoption Intentions(2005-10) Taylor, Nolan J.Widespread use of Internet-capable personal computers has enabled extremely powerful virtual computers or “grids”. These grids have applications for both business problems (e.g., automotive design) and social problems (e.g., drug evaluation). Many of these grids have sought to improve efficiency by processing multiple grid projects using the same network infrastructure and grid participants. This presents challenges for integrating projects in a manner such that public acceptance is greatest. The results suggest that both the order in which the individual projects are introduced and the manner in which the projects are integrated are both important determinants of public acceptance.Item Information foraging on the web: The effects of “acceptable” Internet delays on multi-page information search behavior(2006-11) Taylor, Nolan J.; Dennis, Alan R.Web delays are a persistent and highly publicized problem. Long delays have been shown to reduce information search, but less is known about the impact of more modest “acceptable” delays — delays that do not substantially reduce user satisfaction. Prior research suggests that as the time and effort required to complete a task increases, decision-makers tend to reduce information search at the expense of decision quality. In this study, the effects of an acceptable time delay (seven seconds) on information search behavior were examined. Results showed that increased time and effort caused by acceptable delays provoked increased information search.Item Public grid computing participation: An exploratory study of determinants(2007-01) Taylor, Nolan J.Using the Internet, “public” computing grids can be assembled using “volunteered” PCs. To achieve this, volunteers download and install a software application capable of sensing periods of low local processor activity. During such times, this program on the local PC downloads and processes a subset of the project's data. At the completion of processing, the results are uploaded to the project and the cycle repeats. Public grids are being used for a wide range of endeavors, from searching for signals suggesting extraterrestrial life to finding a cure for cancer. Despite the potential benefits, however, participation has been relatively low. The work reported here, drawing from technology acceptance and volunteer literature, suggests that the grid operator's reputation, the project's perceived need, and the level of volunteering activity of the PC owner are significant determinants of participation in grid projects. Attitude, in addition to personal innovativeness and level of volunteering activity, predicted intentions to join the project. Thus, methods traditionally used for motivating volunteer behavior may be effective in promoting the use of grid computing.Item Research Report: Modifying Paradigms—Individual Differences, Creativity Techniques, and Exposure to Ideas in Group Idea Generation(2001-09) Garfield, Monica J.; Taylor, Nolan J.; Dennis, Alan R.; Satzinger, John W.In today's networked economy, ideas that challenge existing business models and paradigms are becoming more important. This study investigated how individual differences, groupware-based creativity techniques, and ideas from others influenced the type of ideas that individuals generated. While individual differences were important (in that some individuals were inherently more likely to generate ideas that followed the existing problem paradigm while others were more likely to generate paradigm-modifying ideas that attempted to change the problem paradigm), the exposure to paradigm-modifying ideas from others and the use of intuitive groupware-based creativity techniques rather than analytical groupware-based creativity techniques were found to increase the number of paradigm-modifying ideas producedItem Situation Normality and the Shape of Search: The Effects of Time Delays and Information Presentation on Search Behavior(2013-05) Taylor, Nolan J.; Dennis, Alan R.; Cummings, Jeff W.Delays have become one of the most often cited complaints of web users. Long delays often cause users to abandon their searches, but how do tolerable delays affect information search behavior? Intuitively, we would expect that tolerable delays should induce decreased information search. We conducted two experiments and found that as delay increased, a point occurs at which time within-page information search increases; that is, search behavior remained the same until a tipping point occurs where delay increases the depth of search. We argue that situation normality explains this phenomenon; users have become accustomed to tolerable delays up to a point (our research suggests between 7 and 11 s), after which search behavior changes. That is, some delay is expected, but as delay becomes noticeable but not long enough to cause the abandonment of search, an increase occurs in the “stickiness” of webpages such that users examine more information on each page before moving to new pages. The net impact of tolerable delays was counterintuitive: tolerable delays had no impact on the total amount of data searched in the first experiment, but induced users to examine more data points in the second experiment.
