The affect system has been shaped by the hammer and chisel of adaptation and natural selection such that form follows function. The characteristics of the system thus differ across the nervous system as a function of the unique constraints existent at each level. For instance, although physical limitations constrain behavioral expressions and incline behavioral predispositions toward a bipolar (good—bad, approach—withdraw) organization, these limiting conditions lose their power at the level of underlying mechanisms. According to the authors ' model of evaluative space ( J. T. Cacioppo & G. G. Berntson, 1994; J. T. Cacioppo, W. L. Gardner, & G. G. Berntson, 1997), the common metric governing approach—withdrawal is generally a single dimension at response stages that itself is the consequence of multiple operations, such as the activation function for positivity (appetition) and the activation function for negativity (aversion), at earlier affective processing stages.

Gesture-based mobile interfaces require users to change the way they use technology in public settings. Since mobile phones are part of our public appearance, designers must integrate gestures that users perceive as acceptable for public use. This topic has received little attention in the literature so far. The studies described in this paper begin to look at the social acceptability of a set of gestures with respect to location and audience in order to investigate possible ways of measuring social acceptability. The results of the initial survey showed that location and audience had a significant impact on a user’s willingness to perform gestures. These results were further examined through a user study where participants were asked to perform gestures in different settings (including a busy street) over repeated trials. The results of this work provide gesture design recommendations as well as social acceptability evaluation guidelines. Author Keywords Social acceptability, gesture interfaces, design recommendations, evaluation methodology.

This paper uses the original Technology Acceptance Model (TAM) and its extension models to explain the factors affecting the use of the mobile Internet services in Korea. Based on data collected from a questionnaire survey, we show that social influence and self-efficacy variables significantly affect perceived usefulness and perceived ease of use, respectively. The data also reveal that both perceived usefulness and ease of use explain a significant percentage of the variations in the attitude toward using the mobile Internet, which in turn influences the actual usage frequency.

psychology. Her clinical internship was in Health Psychology at UCLA Medical Center and her post-doctoral fellowship was at the CPRC. She has fifteen years of clinical and research experience in many medical and reproductive health care settings, and is an investigator on many federally funded research projects studying various health behavior changes. She has ten years of experience in the development and application of the Transtheoretical Model and stage-matched interventions to many problem behaviors. 2 Dr. Joseph Rossi is a Professor in the Department of Psychology and Director of Research at the Cancer Prevention Research Center at the University of Rhode Island. He received his PhD in experimental psychology from the University of Rhode Island in 1984.

Theoretical and empirical research on technology acceptance, while acknowledging the importance of individual beliefs about the compatibility of a technology, has produced equivocal results. This study focuses on further theoretical and empirical development of this important belief in technology acceptance. Specifically, unlike prior research which has examined only one aspect of compatibility, we provide a more comprehensive conceptual definition that views compatibility as a multi-dimensional construct. Based on the conceptual definition of compatibility, we develop operational measures of the multiple dimensions of compatibility. The model is tested using the World Wide Web (WWW) as the target innovation. Scale validation indicates that the operational measures of compatibility developed in this study have acceptable psychometric properties and confirmatory factor analysis supports the multi-dimensional structure of this construct. We then assess the nomological validity of this construct by situating it within the Technology Acceptance Model. In contrast to prior research which has regarded beliefs of compatibility as an independent antecedent of attitude, we posit causal linkages among the three beliefs of compatibility, usefulness, and ease of use. Results largely support the theorized relationships. 1 ON THE MULTI-DIMENSIONAL NATURE OF COMPATIBILITY

Abstract 1 In this paper, we set forth a program of research for identifying the pertinent issues that are affecting the adoption and use of mobile electronic commerce applications and collaborative mobile technologies. The primary vehicle for understanding these issues is the observation and analysis of how different cultures utilize these emerging technologies. For example, why is short message service (SMS) messaging so popular in Europe but barely used in the US? A review of the existing and near-future technologies is provided, along with the differences in national infrastructure as well as culture. The roles of cognitive fit and technology acceptance model (TAM) in addressing these questions are reviewed, along with other relevant literature. Finally, a listing of research questions and a research plan for testing them is detailed. While no research on this plan has yet been conducted by the authors in time for the press deadline, it is hoped that some studies will have been completed and analyzed to the point where preliminary findings can be shared with the conference audience at HICSS itself.

Many Customer-to-Customer (C2C) online auction providers still do not have a good understanding of Customer-to-Customer trade in Taiwan. The Customer-to-Customer online auction providers still do not have a good understanding of Customer-to-Customer trade behavior and are unable to provide satisfied and effective outcomes for an online auction trade. It is difficult to propose a standard trade strategy without a basic understanding of current trade capacity and of the critical gaps incustomer’s trade-evaluation. The purpose of this survey article is to address these behaviors in the literature and to provide an overview of the current state in Taiwan. Using qualitative data collected from customers, this study provides insight into what can be done to build effective Customer-to-Customer online auction trade in Taiwan.

This study investigates two trust building models - Mayer's Factor-Based model, and McKnight's Process-Based model of trust formation. It critically outlines the two different models of trust formation and adapts them for application in an online environment. Through a series of case studies we undertake a preliminary assessment of which model fits better to online shopper behaviors. We use the cases and interviews of online shoppers to understand how trust is formed in new online shopping experiences, and develop preliminary insights into the effectiveness of third party endorsements for trust building. We focus on comparative impact of satisfied customers' individual endorsements and portal affiliation. The findings of interviews raise our understanding of online trust formation and online consumer buying intentions. Also, this study raises a number of hypotheses, and suggests how Internet firms should utilize different endorsement strategies.

Much of the empirical information on E-Commerce activity is based on the U.S. and other developed nations. This study extends our knowledge by conducting a comparative investigation of B2C Internet shopping in the U.S. and Thailand. A unique feature of the study is the examination of Internet shopping in relation to conventional instore shopping. Data was collected from both countries and statistical analyses were conducted to find differences among consumer preferences and behaviors toward Internet stores. A scale to measure consumer preference is proposed and its Cronbach’s alpha is reported. The results demonstrate that American subjects have a higher acceptance of Internet stores than those who live in Thailand, proving that Internet commerce has not yet penetrated global markets. Based on the study, suggestions are offered on how to conduct electronic business in other parts of the world. 1.
