Business to consumer e-commerce conducted via the mechanism of web-shopping provides an expanded opportunity for companies to create a cognitively and esthetically rich shopping environment in ways not readily imitable in the nonelectronic shopping world. In this article an attitudinal model is developed and empirically tested integrating constructs from technology acceptance research and constructs derived from models of web behavior. Results of two studies from two distinct categories of the interactive shopping environment support the differential importance of immersive, hedonic aspects of the new media as well as the more traditional utilitarian motivations. In addition, navigation, convenience, and the substitutability of the electronic environment to personally examining products were found to be important predictors of online shopping attitudes. Results are discussed in terms of insights for the creation of the online shopping webmosphere through more effective design of interactive retail shopping environments.

Risk perceptions regarding Internet privacy and security have been identified as issues for both new and experienced users of Internet technology. This paper explores risk perceptions among consumers of varying levels of Internet experience and how these perceptions relate to online shopping activity. Findings provide evidence of hypothesized relationships among consumers' levels of Internet experience, the use of alternate remote purchasing methods (such as telephone and mail-order shopping), the perceived risks of online shopping, and online purchasing activity. Implications for online commerce and consumer welfare are discussed.

Design/methodology/approach -Data from a survey of 297 online consumers were used to test the research model. Confirmatory factor analysis was conducted to examine the reliability and validity of the measurement model, and the structural equation modelling technique was used to test the research model. Findings -The analytical results showed that the dimensions of web site design, reliability, responsiveness, and trust affect overall service quality and customer satisfaction. Moreover, the latter in turn are significantly related to customer purchase intentions. However, the personalization dimension is not significantly related to overall service quality and customer satisfaction. Research limitations/implications -Future research can use different methodologies, such as longitudinal studies, focus groups and interviews, to examine the relationship between service quality and customer purchase behaviour in online shopping contexts. Practical implications -This study suggests that to enhance customer purchase intentions, online stores should develop marketing strategies to better address the trustworthiness, reliability, and responsiveness of web-based services. Online stores can devote valuable corporate resources to the important e-service quality attributes identified by this study. Originality/value -This study developed the instrument dimensions of e-service quality by modifying the SERVQUAL model to consider online shopping context. Moreover, the results of this study provide a valuable reference for managers of online stores, as well as for researchers interested in internet marketing.

An analysis of these motives, including online convenience, physical store orientation (e.g., immediate possession and social contact), information use in planning and shopping, and variety seeking in the online shopping context, suggests the existence of four shopping types. These four types are labeled convenience shoppers, variety seekers, balanced buyers, and store-oriented shoppers. The convenience shopper is more motivated by convenience. The variety seeker is substantially more motivated by variety seeking across retail alternatives and product types and brands than any other shopping type. Balanced buyers are moderately motivated by convenience and variety seeking. The store-oriented shoppers are more motivated by physical store orientation (e.g., the desire for immediate possession of goods and social interaction). Shopping types are profiled in terms of background variables and the propensity to shop online. The results are contrasted with a matched sample of off-line shoppers. Implications of this typology for theory and practice are discussed. D

A model explaining the impact of different factors on online shopping intentions and behavior is developed based on the Theory of Planned Behavior. The model is then tested empirically in a longitudinal study with two surveys. Data collected from 705 consumers indicate that subjective norms, attitude, and beliefs concerning the consequences of online shopping have significant effects on consumers' intentions to buy online. Behavioral control and intentions significantly influenced online shopping behavior. The results also provide strong support for the positive effects of personal innovativeness on attitude and intentions to shop online. The implications of the findings for theory and practice are discussed.

Hundreds of millions of social network users reveal great amounts of personal information in the Web 2.0 environment that is largely devoid of security standards and practices. The central question in this article is why so many social network users are being so trusting. The focus is on theory-building on trust as a critical issue in OSNs. A theoretical framework is developed, which facilitates a multi-level and multi-dimensional analysis of research problems related to trust in OSNs. First, the structural and relational underpinnings of trust in OSNs are investigated from a governance perspective that integrates concepts of social network theory, social capital and the role of value in relational exchanges. Subsequently, the focus moves to the individual's decision to trust and to processes through which trust actually emerges. Different types and sources of trust from the trust literature and their importance for trust-related decisions and behaviours in OSNs are discussed. Several research propositions are presented, which contribute to a better understanding of the role of trust and the relevance of facets of trust and social capital in OSNs.

To accomplish this, a review of the empirical studies on the antecedents of online shopping was performed. From an extensive literature search, a total of 45 relevant articles were identified. The factors that have been investigated in these studies were classified according to their similarity and patterns of their findings were identified and analyzed. #
