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

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.     

Understanding the overvaluation of facial trustworthiness in Airbnb host images

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.

Motivational beliefs as mediators in the association between perceived scholastic competence,self-esteem and learning strategies among Greek secondary school students

The present study investigated the links between self-motivational beliefs, perceived scholastic competence, self-esteem and learning strategies among 134 Greek junior high school students in the subject of Greek language, through self-report. A model was tested with motivational constructs as mediators between perceived scholastic competence and self-esteem on the one side and participants’ learning strategies in language on the other. Mediation analyses results showed that perceived scholastic competence predicted all learning strategies both directly and indirectly through intrinsic goal orientation and task value. Self-esteem was not found to predict learning strategies directly, but only indirectly through intrinsic goal motivation. The findings are discussed in terms of their educational implications.     

A Person-Centered Approach to Students' Evaluations of Perceived Fear Appeals and Their Association With Engagement

A person-centered approach was employed to investigate how students' evaluation of perceived teacher utility value messages, i.e., fear appeals, as a threat and as a challenge, combined within individuals and how these combinations related to student engagement. Two studies were conducted with students in their final two years of secondary education. Empirically distinct clusters emerged at two time points in the academic year. Evaluating the message in the fear appeal at a higher level of challenge than threat was beneficial. Unexpectedly, high threat was associated with high engagement, as long as high challenge was also present, however, this combination was also related to high emotional disaffection. Moderate threat combined with moderate challenge had the most detrimental relationship with student engagement. Educational interventions should aim to increase the likelihood of a challenge evaluation.     

The Determinants of Students' Perceived Learning Outcomes and Satisfaction in University Online Education: An Empirical Investigation*

In this study, structural equation modeling is applied to examine the determinants of students' satisfaction and their perceived learning outcomes in the context of university online courses. Independent variables included in the study are course structure, instructor feedback, self‐motivation, learning style, interaction, and instructor facilitation as potential determinants of online learning. A total of 397 valid unduplicated responses from students who have completed at least one online course at a university in the Midwest were used to examine the structural model. The results indicated that all of the antecedent variables significantly affect students' satisfaction. Of the six antecedent variables hypothesized to affect the perceived learning outcomes, only instructor feedback and learning style are significant. The structural model results also reveal that user satisfaction is a significant predictor of learning outcomes. The findings suggest online education can be a superior mode of instruction if it is targeted to learners with specific learning styles (visual and read/write learning styles) and with timely, meaningful instructor feedback of various types.     

Is it time well spent? The relationship between time management behaviours,perceived effectiveness and work‐related morale and distress in a university context

Despite the high ‘guru‐factor’ in time management, few claims have been subjected to empirical investigation. This study tests the claims that people who manage their time well perceive themselves to be more effective and feel less stressed. University staff and students were utilized to investigate the relationship between time management related behaviours, perceived effectiveness, and work‐related morale and distress. Results suggested a hierarchy of time management behaviours. Having a clear sense of career purpose was most important for perceived effectiveness at work, followed by planning and prioritizing. This study has significant practical implications for staff and students. If the aim of using time management strategies is to improve performance and reduce stress, people need to learn to identify the purpose in their career, then plan their time accordingly, rather than tidying desks and hanging ‘do not disturb’ signs on doors.     

The roles of habit and web site quality in e-commerce

Previous research has primarily examined consumers’ perceived usefulness of web sites and trust in the web retailer as two major predictors of web site use and e-commerce adoption. While the consumers’ repeated behavior in the past (i.e., habit) may contribute to continuance behavior, it has not been investigated. This article includes habit as a primary construct along with perceived usefulness and trust to predict and explain consumers’ continued behavior of using a B2C web site. Additionally, included are several web quality measures as antecedents to trust and perceived usefulness. The research model is evaluated using structural equation modeling. Results show that consumers’ behavioral intentions to continue using a B2C web site are determined by all three key drivers: perceived usefulness, trust, and habit. Furthermore, not all dimensions of web quality have a significant effect on perceived usefulness and trust.     

环境领导力对企业生态创新的影响机制研究

    管理者的环境领导力和环保认知对企业生态创新决策起到决定性作用。然而,关于管理者的环境领导力能否对生态创新产生影响,究竟产生怎样的影响以及其影响机理至今尚未深入探讨。本文基于自然资源基础理论和领导力理论,从高层管理者认知的角度出发,构建了“环境领导力→高管感知→生态创新行为”的心理决策框架,以更好地解释高管的环境领导力对于不同战略姿态的生态创新（被动式生态创新和主动式生态创新）的影响,以及影响的不同路径。通过对248家制造业企业问卷调查,研究结果表明：环境领导力对主动式生态创新存在显著影响;而对被动式生态创新影响没有通过检验。高管的机会感知在环境领导力与主动式生态创新之间存在部分中介效应;而威胁感知在环境领导力与被动式生态创新行为之间存在完全中介效应。
