Spreadsheet Visualization Effects on Error Correction

Spreadsheets have been used by organizations for decades. Errors in spreadsheets are commonly found in laboratory and field findings. In recent years, many exciting new visualization techniques have been developed to help users understand spreadsheet models and to check for errors. Two visualization tools were tested in an experiment for their effects on error correction. The first is a simple arrow tool which shows dependencies among cells. The second shows the inputprocess- output function of cells in addition to the dependency arrows. The experiment shows significantly better error detection with the arrow method than for the plain method (without visualization tools). Wrong data errors took more time to correct than missing data errors

Effects of Choice Contrast and Order Sequence on Consumer Judgment and Decision in Comparison- Shopping Assisted Environment

Comparison-Shopping (CS) websites, such as mySimon.com, assist consumers in managing the vast amount of information offered by multiple retailers on the Internet. Conventional wisdom would have dictated that the provision of the best set of alternatives by CS websites should lead to high consumer satisfaction and purchase propensity. However, consumers may experience decision difficulty to choose among alternatives that are nondominated (i.e., none of the alternative is inferior for all product attributes). Consequently, they may simply avoid making a decision by not committing to any purchase. Grounded on behavioral and context-dependent decisionmaking literature, this paper builds a model that explores the effects of choice content and choice order sequence on consumer behavior and explains how they can potentially alleviate the difficulty of making purchase decisions

Evaluation of the Impacts of Data Model and Query Language on Query Performance

It is important to understand how users can utilize database systems more effectively to enhance performance. A major research interest is to evaluate and compare user performance across different data models and query languages. So far, experiments have tested combinations of model plus language. An interesting theoretical and practical question is: how much of the performance difference is caused by the data model itself, and how much by the additional query language syntax? A cognitive model of query processing suggests measurement at two stages. The data model has impact at the first stage, and the model with the query language syntax together has the impact at the second stage. An experiment that compares the objected-oriented and relational models and query languages at the two stages provides fresh results

Government Regulation of Online Game Addiction

While the Internet has changed the world with online knowledge, communication, and collaboration, it has also introduced online addiction. Online game addiction can be severe with tragic outcomes. Most governments and organizations are yet to recognize the severity of online game addiction and the need for intervention. We briefly review the literature on online game addiction. We also summarize the limited attempts of governments to develop regulations aimed at preventing online game addiction. Special attention is paid to China and its efforts to reduce the number of hours that young people can play online. We present evidence suggesting that online game addiction is an issue that should be considered by governments everywhere and that information systems researchers can play an important role in analyzing the impacts of government regulation of online addiction and shaping regulation improvements

Understanding Users\u27 Continuance of Facebook: The Role of General and Specific Computer Self-Efficacy

Prior research has distinguished general computer self-efficacy (CSE) and application-specific computer self-efficacy, but few studies have investigated the relationship between the two levels of CSE as well as their antecedents and consequences. With the increasing popularity of social networking sites such as Facebook, we are interested in assessing the role of general and specific CSE in predicting users\u27 continuance intention of these sites. An extended technology acceptance model with both cognitive and affective predictors is utilized to capture the decision process of Facebook users\u27 continuance intention. The proposed research model examined antecedents as well as consequences of both general CSE and specific CSE in Facebook. A survey was conducted for data collection. The results show that general CSE and specific CSE are closely related but play different roles in predicting continuance intention in Facebook through cognition and affect, and are affected differently by general computer and Facebook-specific experience

The Medium Matters: Effects on What Consumers Talk about Regarding Movie Trailers

Entertainment consumers are known to consult others’ opinions to make consumption decisions via social media. However, little research has investigated whether various configurations of communication media design features affect what consumers talk about regarding movie trailers. To address the research question, we integrate past research on psychological drivers of interpersonal communication and computer-mediated communication to propose that different commentary presentation of social media would affect the relative importance of communication motivations, which in turn shapes the specific messages communicated (i.e., valence, informational content, and emotional content). We propose two studies to test our research model and hypotheses. We hope to contribute to the literature by empirically investigating the creation of specific types of messages, elucidating the role of configuration of social media design features in shaping the messages communicated, and highlighting the impacts of interface design on achieving interpersonal communication goals

Push Yourself a Bit Harder: The Impacts of Force-based Gestures on Consumer Decisiveness and Self-Regulation

The emergence of force-based gestures (e.g., peek and pop) brings more functionalities to mobile interaction. Although it is believed that peek and pop could facilitate user navigation experience, the psychological and behavioral effects of force-based gestures remain unexplored. This study aims to investigate whether and how force-based gestures (gentle tap vs. hard press) influence mobile consumer decision making. Drawing on Embodied Cognition Theory and Mobile Application Usability literature, we propose that hard press (compared with gentle tap) could make consumers more decisive and thus lead to faster decisions; moreover, hard press (compared with gentle tap) could also facilitate willpower summoning and thus enhance consumer self-control. We also propose that these effects are contingent on visual responsiveness. Accordingly, a 2 by 2 lab experiment is designed. Potential theoretical contributions, practical implications as well as future research directions are discussed
