The mediating role of consumer trust in an online merchant in predicting purchase intention

It is widely known in related literature that trust in a merchant reduces the perceived risk of an online transaction. However, there are theoretical reasons to postulate that the perceived risk acts as a barrier to consumer trust. Furthermore, existing studies suggest that trust is an important predictor of purchase intention. Thus, this research aims at investigating the mediating role of consumer trust in an online merchant in the relationships between components of perceived risk and purchase intention: (1) examining the total effect without mediation, and (2) examining the mediation effect. When we probed the total effect, the findings revealed that performance, psychological, financial, and online payment risks have a significant negative influence on purchase intention. On the other hand, an examination of the mediation effect indicated that trust in an online merchant completely mediates the effect of performance risk, but partially mediates that of the psychological risk. Given the mixture of unmediated as well as mediated effect of perceived risks on purchase intention, the paper concludes that efforts, made by online merchants, to lessen certain types of risk will first improve consumer trust, and then ultimately, increase consumer's intention to buy online.

人工入化与自然天成——江西派诗学与严羽诗学比较研究之四

严羽对气象浑厚的推崇,几乎贯穿整部《沧浪诗话》,并多次指斥江西诗派乏浑厚气象.江西诗派很强调法度,从语词的锤炼到句法的安排,都要精研细究,致不少作品有雕琢之痕.但在主观意识上、在理论追求中,江西诗派和严羽有着相同的归趣,即气象浑厚;只是在臻至这一目标的道路选择上,他们表现出不同的取向：江西诗派倡导由人工而入化,严羽崇尚任自然而天成.

“Safe Harbor”: Evaluation of a professionalism case discussion intervention for the gross anatomy course

Medical professionalism is a multifaceted paradigm and is an essential component of medical education. Gross anatomy is a laboratory to teach professionalism, and promoting critical reflection in medical students is a prerequisite to furthering professionalism. The aim of this study was to determine if professionalism case discussions during a Gross Anatomy course improve students' reflections using a validated reflection instrument (12 items; five‐point Likert scale where 1 = Disagree, 2 = Disagree with reservation, 3 = Neutral, 4 = Agree with reservation, 5 = Agree). Four facilitated reflection sessions were aimed at fostering reflective capacity through reflection on elements of professionalism. Results did not show a significant change between pre‐and postintervention reflection scores (3.45 ± 0.61 vs. 3.48 ± 0.51; P = 0.82). Historical control students were found to have significantly higher reflection scores when compared with postintervention students (3.91 ± 0.53 vs. 3.48 ± 0.51; P < 0.001). However, the historical control students were found to have significantly higher professionalism scores (P = 0.001) as compared with the intervention students. Student satisfaction was high, with 25 of 28 (89.2%) students reporting that the sessions should be included as a component of future anatomy courses. While reflection scores were not significantly increased as a result of the intervention, students expressed appreciation for the opportunity to discuss professionalism issues related to the dissection of cadavers. Additionally, the intervention students had both lower professionalism scores and lower reflection scores, which supports the idea that highly professional students are more capable of reflecting on professionalism. Future studies should determine whether this case discussion intervention improves objective measures of professionalism. Anat Sci Educ 7: 191–198. © 2013 American Association of Anatomists.     

The relationship between university student learning outcomes and participation in social network services,social acceptance and attitude towards school life

Educators try to use social network services (SNSs) in their teaching because they are regarded as beneficial to student learning. However, little research to date has empirically investigated whether the use of an SNS increases university student learning outcomes. A total of 730 university students in the capital area of South Korea participated in the present study. Based on social learning theory, we developed a general structural model that included SNS participation (SP) as an exogenous variable and a range of endogenous variables: cognitive domain learning outcomes, affective domain learning outcomes, social domain learning outcomes, social acceptance (SA) and attitude towards university life (AT). The study results confirmed that the model adequately explained causal relationships between student learning outcomes and SA, AT and SP. SA was identified as a key variable because of its direct effect on learning outcomes. However, SP was considered more important because of its large indirect effects on all learning outcomes through both SA and AT.

地方院校教学质量保障体系研究

一、影响地方院校教学质量的主要因素 （一）教育经费投入不足 由于扩招。生均教育经费实际在下降。我国教育经费的投入自1994年以来一直在2．5％左右徘徊,而且主要投资在中央部委院校,地方院校投入的经费仅占很小一部分。为了改变这一状况,各省市积极采取行动,加强教学基础设施建设,但扩招速度超过了经费投入速度,生均教育经费在不断下降。教育经费投入的不足已严重地制约着地方院校的改革、发展和质量的提高。
