Lacking the presence of human and social elements is claimed one major weakness that is hindering the growth of e-commerce. The emergence of social commerce might help ameliorate this situation. Social commerce is a new evolution of e-commerce that combines the commercial and social activities by deploying social technologies into e-commerce sites. Social commerce reintroduces the social aspect of shopping to e-commerce, increasing the degree of social presences in online environment. Drawing upon the social presence theory, this study theorizes the nature of social aspect in online SC marketplace by proposing a set of three social presence variables. These variables are then hypothesized to have positive impacts on trusting beliefs which in turn result in online purchase behaviors. The research model is examined via data collected from a typical e-commerce site in China. Our findings suggest that social presence factors grounded in social technologies contribute significantly to the building of the trustworthy online exchanging relationships. In doing so, this paper confirms the positive role of social aspect in shaping online purchase behaviors, providing a theoretical evidence for the fusion of social and commercial activities. Finally, this paper introduces a new perspective of e-commerce and calls more attention to this new phenomenon of social commerce. 相似文献

This paper analyses the relationship between productive efficiency and online-social-networks (OSN) in Spanish telecommunications firms. A data-envelopment-analysis (DEA) is used and several indicators of business “social Media” activities are incorporated. A super-efficiency analysis and bootstrapping techniques are performed to increase the model's robustness and accuracy. Then, a logistic regression model is applied to characterise factors and drivers of good performance in OSN. Results reveal the company's ability to absorb and utilise OSNs as a key factor in improving the productive efficiency. This paper presents a model for assessing the strategic performance of the presence and activity in OSN. 相似文献

This article examines the differential formation of online news startups in Toulouse, France, and Seattle, United States. While Seattle is home to many startups, in Toulouse there have been just 4—and only 1 continues publishing. Drawing on Bourdieu's field theory, we argue that amount and types of capital held by journalists in the 2 cities varied as a result of differences in journalism's position in the field of power. These differences shaped the extent of startup formation in each city and structured journalists' capacities to convert their capital into the resources needed to form startups (e.g., funding, credentials, partnerships). These findings are positioned in relation to literatures on journalism innovation and comparative media. 相似文献

There is a substantial increase in the utilization of web-based assessment procedures to assist teaching and learning processes in higher education institutions. Despite their benefits, institutions use them to a limited extent due to a number of factors influencing both instructors' and students' behaviors. This study examines students' acceptance of a web-based summative listening test administered in the 2014–2015 academic year within an ‘English as a Foreign Language' course at a two-year post-secondary military school in Turkey. The participants consisted of 602 military students. As a model, Computer Based Assessment Acceptance Model based on Technology Acceptance Model was adopted in order to analyze the participants' perceptions on a web-based summative listening comprehension test. The data were collected via an online questionnaire. A structural equation modeling analysis was utilized to analyze the relationships among factors. The general results showed that perceived ease of use and perceived playfulness had a direct influence on the participants' behavioral intentions to use web-based tests. In other words, web-based tests are expected to be used if they are easy to use and playful enough. 相似文献

We propose a general method for predicting multiple steps ahead of our target system and estimating simultaneously the prediction errors in a real time. The requirement of the proposed method is that we have a time series of the target system. We demonstrate the method by artificial data, real wind speed data, and real solar irradiation data. 相似文献

The security and privacy issues have been well investigated in typical vehicle ad hoc networks. However, considering the drive-thru Internet properties, in particular for a secure and in-motion payment services case, merely implementing the existing online payment schemes may be either infeasible or inefficient. In this paper, we propose an advanced online payment framework, which integrates three main features, including the novel pairing-free certificateless encryption, signature and semi-honest RSU-aided verification, and the CA-aided tracking and batch auditing, and providing following properties independently, e.g., achieving a higher trust level and supporting primary security services, introducing a semi-honest RSU to indicate more practicality, and optimizing the verifying and auditing efficiency for a large number of authentication requests case. Performance evaluations such as security analysis, efficiency analysis, and simulation evaluation show the security and feasibility of the proposed framework. 相似文献

This research challenges the presumption that reading online reviews solely affect reader attitudes toward a prospective decision. Instead, readers may strategically select and read reviews after a decision. This research advances and tests hypotheses proposing that: (1) post-decision readers select decision-supportive reviews earlier and more frequently; and (2) the reviews they read affect the subsequent cognitive dissonance they experienced. Two studies employed an original post-decision experiment and demonstrated that readers expressed biased review selection. Interestingly, the reviews they read affected and increased their cognitive dissonance. The findings contributed to understanding the complex dynamic of online reviews in a post-decision context. 相似文献

A promising solution to reliability challenges in nano-scale fabrication technologies is self-test and reconfiguration. In this direction, we propose an autonomous test mechanism for online detection of permanent faults in many-core processors. Several hardware test components are incorporated in the many-core architecture. Some of these components distribute software-based self-test routines among the processing cores and make each test routine accessible for a limited amount of time. A processing core that has an idle slot executes the test routine, otherwise it skips it without loss of test continuity. Several components of the proposed test architecture monitor behavior of the processing cores during execution of test routines, detect faulty cores, and make their omission from the system possible. We propose the use of an extended form of Petri NET modeling method to model and analyze the proposed test mechanism and tune our test architecture to preserve quality of test, and at the same time, manage the overall test time. Our experimental results show that test time and hardware overhead of the proposed test mechanism are low and its performance overhead is zero. Furthermore, the proposed test architecture can efficiently scale to a many-core with a large number of processing cores. 相似文献

This study uses eye-tracking method to investigate consumers' online review search behavior by suggesting that it needs to consider the type of product reviewed. A review-product congruity proposition was testified through a self-report survey and an eye-tracking experiment. The proposition states that consumers of search products expect to seek attribute based reviews, while consumers shopping for experience products tend to seek experience based reviews. Two experiments were conducted in the human factors & ergonomics laboratory of Beihang University, China and all subjects are college students. The results of our first empirical experiment support our hypotheses by showing consumers' more active and positive responses to attribute based reviews when shopping for search products and to experience based reviews when purchasing experience products. The second experiment was conducted with eye tracking method to gain further insights. We found that consumers of search products are attracted and engaged more deeply by attribute based reviews. However, when they browse experience products, the difference of their fixations on experience based reviews and attribute based reviews is not significant, and thus the proposition is partially supported. This study extends our current understanding of consumers' online review search behavior by subsuming product type, which is necessary and helpful, and provides references on the classification and presentation of reviews to facilitate consumers' product judgement and decision making. Moreover, comparison of traditional empirical method and eye-tracking method can help deepen our understanding of complex consumer online shopping behavior. 相似文献

The success of online games encouraged the development of gamification software in e-banking. Beside the growing trend of gamification, it is important understand how bank customers face the gamified applications, particularly as enjoyment and ease-of-use. To assess the determinants that influence the adoption of gamification in e-banking, we developed a research to propose a conceptual model that illustrates the adoption of gamified business applications by bank customers, in e-banking context. We conducted two quantitative studies (A and B) to understand how bank customers represent a gamified business software and its changes (or improvements) over time. Study A was performed in 2012 (N = 183), and study B in 2015 (N = 219). Online bank customers were invited to rate the importance of variables related to: socialness, ease-of-use, usefulness, enjoyment and intention to use e-banking systems with game features and social cues. The results show that ease-of-use and enjoyment are interrelated, and both have influence in e-banking usage. This study present theoretical ground of the conceptual model, and discuss two empirical studies, aiming to analyse the ease-of-use and enjoyment influence on bank customers. These findings will contribute directly to explain of adoption hedonic business software in e-banking. 相似文献
