    Perceived quality and motivations on intention-to-use of a general web portal
    ( 2008) Nam, Junghyun
    The purpose of this research was to study the quality and motivation attributes of information products from the end-users' perspective, and to measure the impact of these attributes on intention-to-use. An information product is defined as a highly interdependent package of information that can be transmitted or distributed in digital form (e.g., a web portal, an application software). In the context of Web portal use, the information product generally includes three types of services: personal services (e.g., email), information services (e.g., online news) and search services. The literature suggests that the quality of an information product can be assessed from a number of attributes, such as accuracy and applicability of the information content, the timeliness and speed of the physical medium, and the reliability and responsiveness of the product provider. The literature also underscores the importance of motivational factors such as social escapism and privacy concerns on the intention to use. Drawing from this theoretical background, an initial set of 21 quality and motivation attributes has been identified, and an experimental study using 142 subjects as Web portal users has been conducted. Statistical analyses helped us consolidate quality factors into four groups of quality attributes factors as they were perceived by the Subjects: Content relevancy, Communication interactiveness, Information currency, and Instant gratification. As far as impact analyses are concerned, social escapism motivation, information motivation, interactive control motivation, and socialization were found to highly correlate to all of the three types of services and the combined use. When quality factors and motivations were considered at the same time to explain intention-to-use of the Web portal, social escapism, as a motivation factor, was identified as the main determinant. The findings of this research shed new lights on the understanding of Web portal use and suggests that there are some quality attributes that are particularly perceived to be relevant to Web portal intention to use. Lessons learned from this study should also help IT professionals to design, develop and deploy more effective general web portals.

    Adoption of cellular telephone technologies and services : user perceptions and motivations in the United States (Hawaii) and South Korea
    ( 1996) Kwon, Hyosun
    Since commercial cellular telephone services began in 1983 in the United States, cellular telephones have proliferated worldwide; however, few academic researchers have studied why and how cellular telephones are adopted and used by the general public. Thus, the objective of this study is to gain a more complete understanding of people's acceptance of cellular telephones. Two hundred and ninety-three cellular telephone users from the United States (Hawaii) and South Korea were surveyed through questionnaires that examined individuals' demographic and socio-economic characteristics, perceptions about cellular telephones (the perceived ease of and apprehensiveness about use of telephones), motivations to use cellular telephones (extrinsic motivations, intrinsic motivations and social pressure), and extent of cellular telephone use. In particular, this study explored the following questions: 1. What are the impacts of users' demographic and socioeconomic factors, including gender, age, occupation and income, on their perceptions and social pressure? 2. What are the impacts of users' perceptions on their extrinsic and intrinsic motivations to use cellular telephones? 3. What are the impacts of the three motivational factors on use of cellular telephones? 4. Are cultural differences discernible between cellular telephone users in South Korea and the United States? These questions were tested using an integrated theoretical model. The model was developed in this study based on existing theories of motivation and explained the relationships between individual characteristics, users' perceptions, motivations, and the usage of cellular telephones. This study is one of the first to analyze these issues theoretically in relation to cellular telephones. The results of this study confirm that users' perceptions are significantly associated with their motivations, and that extrinsic motivations are among the most influential factors affecting cellular telephone usage. There were significant differences in perceptions, motivations, and extent of cellular telephone usage between the U.S. and South Korean samples. In this regard, culture plays a key role in technology adoption and use. Managerial and theoretical implications of this and other results are examined.
