Information Technology Usage Transfer in Online Context: A Brand Extension Perspective

Information technology (IT) adoption and acceptance have been the subject of increasing interest and scholarly investigation by information system researchers for over a decade. However, most have examined the usage behavior of various IT products in isolation while the brand nature of technology products has been generally ignored. The current study examines usage transfer behavior from the brand extension perspective and identifies salient determinants of brand extension effect in the adoption Web-based technology. Drawing upon the categorization theory, we propose a research model and try to validate it using cross-sectional field data collected for a search engine and its extensions to a virtual community and web portal. This research contributes to both research and practice by advancing understanding of transfer behavior between products sharing the same brand as well as by providing insights on technology product design and marketing promotion strategies in electronic markets

Mechanisms of the Regulation of the Intestinal Na+/H+Exchanger NHE3

A major of Na+ absorptive process in the proximal part of intestine and kidney is electroneutral exchange of Na+ and H+ by Na+/H+ exchanger type 3 (NHE3). During the past decade, significant advance has been achieved in the mechanisms of NHE3 regulation. A bulk of the current knowledge on Na+/H+ exchanger regulation is based on heterologous expression of mammalian Na+/H+ exchangers in Na+/H+ exchanger deficient fibroblasts, renal epithelial, and intestinal epithelial cells. Based on the reductionist's approach, an understanding of NHE3 regulation has been greatly advanced. More recently, confirmations of in vitro studies have been made using animals deficient in one or more proteins but in some cases unexpected findings have emerged. The purpose of this paper is to provide a brief overview of recent progress in the regulation and functions of NHE3 present in the luminal membrane of the intestinal tract

Competitive Action in Diffusing of Internet Technology: Implications for Local Vendors Defending their Turf against Multinational Incursion

This paper explores the extent to which diffusing Internet technology products is a function of the competitive actions of local online vendors and their respective multinational challengers in emerging electronic markets. Drawing on the perspectives of competitive technology diffusion and Austrian firms’ market process, we developed a set of hypothesis concerning the characteristics of competitive actions that local vendors implemented and the impact of these actions on the dominance of Internet technology products in electronic markets. We then validate the model with longitudinal field data from two pairs of Internet technology products in the search engine and consumer-to-consumer (C2C) electronic market. Our findings suggest that diffusing Internet products can be predicted by the dynamics of specific market-oriented actions. Such a pattern supports the conclusion that local online vendors have significant local advantage in fast-growing emerging markets. We also examine the policy implications of our results, especially with respect to how competitive action can help local online vendors defend their turf against multinational incursion

Determinants of Information Technology Usage Habit

Habit has been investigated as an antecedent of the information systems usage in a few literatures recent years. But little effort has been found on the determinants of habit itself in the information systems research. Drawing upon the insights from goal-directed behavior, habit/automaticity perspective, and IS continuance model, this paper proposes a research model for understanding the antecedents of the individual information technology usage habit. This study suggest that individual satisfaction, perceived enjoyment and user experience positively influence the strength of usage habit, and that perceived usefulness, confirmation of expectation and perceived enjoyment positively affect satisfaction. The implications are discussed, and contributions of this study are presented

Steps on the road of appeasement : British foreign policy-making 1931-1939

This thesis studies the step-by-step process of foreign policy making within the British Government from 1931 to 1939. It aims to pin-point the origin, evolution and nature of appeasement, the principal policy-makers' viewpoints and activities in policy formulating and their responsibility for encouraging the aggressive powers. In the Introduction, the subjective and objective roots of appeasement are explored, and the Author examines the reasons why it was pursued for nine years without change. Highlighting the shortcomings in the past and current research on the subject, a summary of the approaches used in the thesis is given. The First Chapter surveys policy-making during the Manchurian crisis of 1931, not only a starting point for appeasement, but also to a large extent the main reason for the European appeasement. The Second Chapter shows how the British Government appeased Mussolini in the Italo-Abyssinian conflict of 1935-36, and how appeasement in the Far East started to cause appeasement in Europe. Chapters Three, Four and Five indicate the development of appeasement policy towards Germany during 1936 - 1939, namely, how it was hatched during the Rhineland crisis of 1936, and how it was, through the Anschluss, brought to a climax at Munich in 1938. Chapter Six analyses the policy of the guarantee to Poland and of the Three Power conversations in 1939 with the observation that these represented the Chamberlain Government's efforts to change their policy within the scope of appeasement, but that appeasement led to their failure. In the Conclusion, the various arguments in favour of appeasement are criticised and lessons drawn from that disastrous age

Product Integration Formats and Consumers’ Evaluations of the Online Extended Product: a Product Integration Perspective

After launching new products, firms are spending substantial amount of resources into cross-product integration to attract traffic. While customers place increasing value on product integration, little is known about the influence of product integration on consumers’ evaluation of extended product. Based on the product presentation perspective, this study proposed and validated a research model through a scenario-based experiment. The findings suggest that value added integration, rather than the data interface and add-on module integration, is associated with a higher level of perceived diagnosticity. Perceived diagnosticity had a significant influence on consumers’ evaluations of the extended product. This study contributes to the research and practice by providing insights about product promotion within the online context

Quantifying the Effect of Mobile Channel Visits on Firm Revenue

The explosive penetration of mobile devices is one of the most prominent trends in e-business. Although the importance of mobile channel has prompted growing literature, little is known about the revenue implications of customer visit toward mobile channel. This study examines (1) the differential effect of mobile visits in affecting firm revenue (i.e. mobile vs. desktop visits), and (2) which type of mobile visits are more effective (i.e., direct vs. search engine and referral traffic; visits for high vs. low involvement products). We collect an unique objective daily data from a leading online travel agency in China. With a vector autoregressive (VAR) method, we find that, compared with desktop channel, mobile channel visits have shorter carryover effect, but larger short-term effect on firm revenues. Further, mobile channel has larger short-term effect on firm revenues for search engine traffic and lower involvement products. Our findings provide important theoretical contributions and notable implications for mobile commerce strategy
