This research investigates the factors that influence the use of ubiquitous computing and U-business value. It considers system, information and service qualities as the major factors affecting the use of ubiquitous computing. System quality is measured by accessibility, stability and ease of use. Relevance, accuracy and timeliness are used to measure information quality. Reliability, quickness and secrecy are used to measure service quality. U-business value measures the value created from business operations, business processes, and customer relationships improved by the use of ubiquitous computing. Our results show that system accessibility, information accuracy and timeliness, and service quickness exert crucial influences on ubiquitous computing use. We also find that the use of ubiquitous computing creates value by enhancing business operations, business processes, and customer satisfaction. These findings suggest that information quality is relatively more important than system and service qualities for the creation of value in a ubiquitous computing environment. Our research model and empirical results provide valuable indicators for the direction of future research and also suggest managerial guidelines for the successful development and adoption of ubiquitous computing within an organization. 相似文献

Third-year College Retention and Transfer: Effects of Academic Performance, Motivation, and Social Connectedness 总被引：1，自引：0，他引：1

We studied the effects of academic performance, motivation, and social connectedness on third-year retention, transfer, and
dropout behavior. To accommodate the three outcome categories and nesting of data within institutions, we fit a hierarchical
multinomial logistic regression path model with first-year academic performance as a mediating effect. Our sample included
6,872 students representing 23 four-year universities and colleges. This work expands the current state of persistence research
by (1) considering the effects of motivation and social connectedness on college persistence beyond the first year of college,
(2) testing whether the effects of motivation and social connectedness on third-year retention and transfer are direct, indirect,
or both, and (3) testing whether the effects of academic performance, motivation, and social connectedness are different for
retention and transfer. We found that academic performance has large effects on likelihood of retention and transfer; academic
self-discipline, pre-college academic performance, and pre-college educational development have indirect effects on retention
and transfer; and college commitment and social connectedness have direct effects on retention. Academic self-discipline led
to greater first-year academic performance, which suppressed its effect on retention and transfer. Practical and theoretical
implications of these findings and directions for future research are discussed.
A previous version of this paper was presented at the 2nd Annual National Symposium on Student Retention, Albuquerque, New
Mexico, October 2006. 相似文献

The study contributes to the work values literature as well as to the knowledge base of meaning of working in Asian economies.
It represents the results of an empirical study of Korean mid-level employees in diverse industries, investigating the effects
of different understandings of work and non-work dimensions on job satisfaction, career satisfaction, and organizational commitment.
With a sample size of some 420 responses from 16 different companies, age differences were found for overall meaning of work
and also for the effects of importance of working for global organizational commitment. Non-work related dimensions appeared
unrelated to work-related outcome variables. We conclude that to a limited degree, age related differentiation exist in relation
to work meanings and separation of work and non-work domains for work-related effects. The implications for theory and practice
of this research are also discussed. 相似文献

Using the issue of genetically modified foods, this study examines how the Internet may affect the spiral of silence phenomenon in South Korea. More specifically, we explore whether the Internet has created a social environment, where people can exchange opinions more freely without being fearful of social isolation. Analyzing data from an online survey, we first examine whether the Internet can play a role as a source of information, from which people assess the climates of public opinion. Also examined is whether the opinions of netizens can comprise another form of opinion climate, exerting pressure on one's willingness to speak out. Finally, we explore whether expressing an opinion on the Internet is subject to the pressure of opinion climates. Findings suggest that the Internet may play an important role in shaping people's perceptions of opinion climates. Perceived opinion congruence with other people were significantly associated with one's willingness to participate in an online forum, indicating that expressing an opinion on the Internet may be subject to the spiral of silence effect. We conclude that the Internet in South Korea may not have helped to diminish the social pressure that keeps citizens from expressing a minority view. 相似文献

This study explicates the mechanism underlying the process through which news and entertainment media shape people's personal- and societal-level risk perceptions. It combines the psychometric paradigm with the impersonal- and differential-impact hypotheses, highlighting the roles that cognitive and emotional dimensions of risk characteristics play in risk perceptions. Analysis of an online survey among 384 adults from the general population of South Korea in the context of H1N1 flu yields three major findings: (1) exposure to news media is positively correlated with the cognitive dimension of risk characteristics, while exposure to entertainment media is positively correlated with both the cognitive and the emotional dimensions of risk characteristics; (2) the emotional but not the cognitive dimension of risk characteristics is positively related to both personal- and societal-level risk perceptions; and (3) exposure to entertainment media affects personal-level risk perceptions – not directly but indirectly through the emotional dimension of risk characteristics. Theoretically, this study expands the impersonal- and differential-impact hypotheses by explicating their underlying mechanisms and incorporating arguments from the psychometric paradigm. It also adds new knowledge to the psychometric paradigm by highlighting the differential roles of the cognitive and emotional dimensions of people's perceived risk characteristics in risk perceptions. For risk communicators, this study highlights the importance of using entertainment media for shaping risk perceptions and educating the public about risk issues. 相似文献

Inventing is a recombinant process that involves searching and recombining different streams of knowledge. The value of invention is associated with not only how many prior inventions are considered, but also how they are related to each other. We introduce social network analysis broadly used in the social capital theory, and extend the dimension of analysis for the evaluation of patent value. This study employs U.S. pharmaceutical patent data and investigates whether the network characteristic of backward citations have significant effect on the future patent value. The empirical results suggest that the network features of backward citations measured by constraint, cohesion, and efficiency have statistically significant implication on the value of invention in both level and depreciation rate. The study also provides empirical evidence that the exploration strategy is more significantly and positively correlated with the future value of invention compared to the exploitation strategy of inventors. 相似文献

The present and future state of blended learning in workplace learning settings in the United States
This article reports a survey about blended learning in workplace learning settings. The survey found that blended learning gained popularity in many organizations but also that several barriers exist in implementing it. This survey also includes predictions on instructional strategies, emerging technologies, and evaluation techniques for blended learning. 相似文献
