Assessing the effects of consumers’ product evaluations and trust on repurchase intention in e-commerce environments     

《International Journal of Information Management》2018

This study enhances the existing literature on online trust by integrating the consumers’ product evaluations model and technology adoption model in e-commerce environments. In this study, we investigate how perceived value influences the perceptions of online trust among online buyers and their willingness to repurchase from the same website. This study proposes a research model that compares the relative importance of perceived value and online trust to perceived usefulness in influencing consumers’ repurchase intention. The proposed model is tested using data collected from online consumers of e-commerce. The findings show that although trust and e-commerce adoption components are critical in influencing repurchase intention, product evaluation factors are also important in determining repurchase intention. Perceived quality is influenced by the perceptions of competitive price and website reputation, which in turn influences perceived value; and perceived value, website reputation, and perceived risk influence online trust, which in turn influence repurchase intention. The findings also indicate that the effect of perceived usefulness on repurchase intention is not significant whereas perceived value and online trust are the major determinants of repurchase intention. Major theoretical contributions and practical implications are discussed.  相似文献   

Understanding the overvaluation of facial trustworthiness in Airbnb host images     

《International Journal of Information Management》2021

Renting a property via a peer-to-peer platform involves a variety of risks. Humans inherently, subconsciously use facial cues as important shortcuts in making assessments about other persons. On property sharing platforms, such as Airbnb, facial cues can be used in a similar fashion alongside reputational information. According to Dangerous Decisions Theory (DDT), intuitive evaluations of trustworthiness based on faces can bias subsequent assessment of an individual, requiring further information sources to make a more balanced assessment. In this study we apply DDT to demonstrate that evaluations based on perceived facial trustworthiness are overvalued; when combined with reputational measures, such as ‘super host’ status, such assessments are diminished. The study is based on deep learning to classify host faces for a large data set of online accommodation (n = 78,386). The research demonstrates that facial trust cues in online platforms should be treated with caution and must be combined with more objective measures of reputation in order to reduce the effects of overvaluation. The paper concludes with implications for practice and future research.  相似文献

对高校课堂教学评估有效性的反思     

刘向华 《高教发展与评估》2008,24(3):22-26

课堂教学评估是一把"双刃剑",只有做到有所为,有所不为,才能更好地管理教学。有效的教学评估涉及的要素应分为三个样态:既存样态、隐性行为和期待样式。有效的教学评估应以促进教师和学生的发展为目的,应使各方人员参与,以教育性价值为根本,定量和质化方法相结合。  相似文献

On the value of data-based decision making in education: The evidence from six intervention studies     

《Studies in Educational Evaluation》2021

Although some studies have investigated the impact of data-based decision making (DBDM) on student achievement, the overall findings are not straightforward, because of the studies’ methodological flaws and their mixed results. This article first presents a breakdown of the DBDM concept as applied in the Dutch context. Next, it explains the theoretical foundations of DBDM in feedback and goal-setting theory and then discusses various factors influencing DBDM effectiveness. The results of six Dutch DBDM interventions with an explicit focus on student achievement effects of DBDM and with strong research designs are then presented. Significant positive effects on student performance as measured by means of standardized tests are reported for four interventions. The interpretation of student progress data from student monitoring systems does not seem to be problematic for teachers, if they are deliberately trained for it, but teachers do find it difficult to translate student progress data into tailor-made instruction.  相似文献

XOR-MAC消息认证码的安全性新证明     

王大印  林东岱  吴文玲  姜中华 《中国科学院研究生院学报》2006,23(2):257-262

消息认证码（Message Authentication Codes---MACs）是保证消息完整性的重要工具。Bellare 等人提出了称为XOR-MAC的消息认证码，界定了攻击者成功伪造的概率，从而证明了其安全性，但是他们给出的证明方法较为复杂。本文使用Game-Playing 技术采用新的安全性定义证明了XOR-MAC的安全性，证明方法简单明了；在底层所使用的分组密码是伪随机置换的假设下，量化了该消息认证码与随机函数之间区分的概率。  相似文献   

The developmental directions and tasks of the school based curriculum management system in Korea     

Soon Nam Kim 《Asia Pacific Education Review》2005,6(1):41-49

The purpose of this paper is to inquire into the developmental directions and tasks of the School Based Curriculum Management(SBCM) system. The concept of the School Based Curriculum Management can be considered as a subsystem to School Based Management. The logics behind the SBCM system are autonomy, accountability, effectiveness, creativity, professionalism, and participation. The developmental directions of SBCM are to establish and implement the highly autonomous and participative SBCM, the diverse creative SBCM, the highly accountable SBCM, and the professional SBCM. The developmental tasks of SBCM suggested in this study are to establish the School Based Staff Development system, to practice the evaluation system that can control the quality of SBCM, to be managed by a strategic-layer management system, and to constitute the committee of school curriculum.  相似文献
