Interactivity is a key feature of Web sites. This article identifies the determinants that enhance user perceptions of interactivity in a communication scenario in which consumers send instant messages to an e-store. Two conceptualizations of interactivity-telepresence theory and interactivity theory-predict that different antecedents (e.g., the number of clicks, response time, message type) are important. The results of Experiment 1 indicate that message type (i.e., how personal a particular message is) is the strongest predictor of interactivity perceptions. Furthermore, the findings suggest that the effects of message type on perceived interactivity and Web site effectiveness are greater when consumers are complaining than when they are inquiring about services. The results of Experiment 2 show that as the level of message personalization increases, interactivity perceptions and site effectiveness are enhanced (linear relationship). The authors discuss the implications of the findings for theory and practice and provide directions for measuring and manipulating interactivity in further research.

This article introduces several new concepts that lay the conceptual foundation for thinking about next-generation marketing based on ubiquitous networks. U-commerce, orÜber-commerce, is predicated on the characteristics of networkubiquity, universality, uniqueness, and unison. It is proposed that the keys to managing network-driven firms are the concepts of u-space and attention analysis. The implications for next-generation marketing in the u-space are explored, with a research agenda identified for scholars and managerial implications recognized for practitioners.

It was hypothesized in this study that advertising appeals congruent with viewers' self-concept would be superior to incongruent appeals in terms of enhancing advertising effectiveness. Advertising effectiveness was operationalized as: brand memory, brand attitude, and purchase intentions. The sample consisted of 165 subjects who were exposed to four test stimuli (ads), two for automobiles and two for shampoos. One ad within a product class used an introvert appeal, and the other used an extrovert appeal. Congruence between self-concept and the brand image was determined by subjects' evaluations of themselves and the advertised brand. Ad-related tasks included remembering brand names and indicating preference and buying intention for each brand. The study results indicate that brand memory is not mediated by the extent to which advertising expressions are congruent with viewers' self-concept. However, brand preference and purchase intention were shown to be influenced by the self-congruency of an ad. 0

Research on risk is built on a complex array of diverse and sometimes inconsistent definitions, constructs, models, and outcomes. This study examines various literatures to formulate an integrated framework for the conceptualization of perceived-risk processing. The framework specifies three phases (framing, assessment, and evaluation) and their accompanying outcomes of risk attention, perceived risk, and risk-taking propensity. Explicit linkages are specified between situational and individual characteristics. Perceived-risk evaluation is identified as conceptually distinct from assessment of perceived risk, and the construct of risk-taking propensity is separated from those of risk affinity and perceived risk. The framework further presents points of intersection between the literatures on perceived risk and the literatures on consumer decision-making, information search, and satisfaction. Finally, it serves as an anchor for framing future research to promote conceptual and methodological consistency, and to guide progress in directions that are consistent with some leading edge paradigms outside of marketing.
