Do cultural differences affect users’ e-learning adoption? A meta-analysis

The great advantages of e-learning have been recognized, and efforts have been made to promote e-learning adoption. Despite valuable research achievements from technology adoption, previous studies built their models from different perspectives. In this study, to offer a comprehensive research model on e-learning adoption, we integrated these models (ie, TAM, TPB and IDT) and included culture as a moderator. Based on 45 relevant empirical research, this study conducted a meta-analysis to explore key determinants of users’ attitude and behavioral intention to adopt e-learning. Combined with traditional technology acceptance theories and innovation diffusion theory, we developed a comprehensive model and explored the moderating role of culture. The results indicate that this integrated technology acceptance model can be applied to better understand e-learning adoption. The moderator analysis shows that the influence of subjective norms and self-efficacy on users’ behavior intention is more salient in the collectivistic culture, whereas perceived usefulness is more important for online learners in an individualistic culture.     

Substitution of women for men faculty in higher education: Do relative salaries matter?

The paper provides quantitative estimates of the degree of substitutability between men and women faculty in higher education and examines the extent to which price (salary) differentials have played a role in altering the sex distribution in academe. Our results suggest uniformly low own-price elasticities with cross elasticities which differ by academic rank and sex. Further analysis is made of whether institutions of higher education have increased the proportion of females at the upper ranks due to salary factors. Our conclusion is that nonsalary factors appear to have been responsible for the changing sex distribution in academe.

德育:人学的视界

用人学的视界透视德育，是指德育把人学作为一种世界观和方法论，使德育以人学世界观为基点，对德育实践进行深刻、生动的探索、思考、总结，让真实、大写的人突显于德育之中。而德育树立人学世界观考量的标准有：第一，对人的“生存实践性”的正确理解；第二，对人与社会、人与道德、把握人与把握物这三种重要关系的人学理解；第三，把理解与对话作为德育的方法基础。

Effects of applying a VR-based two-tier test strategy to promote elementary students’ learning performance in a Geology class

Science and technology are driving people’s life changes, including education and the environment. Many scholars have attempted to import technology into the classroom to help students learn in different subjects. However, students often need assistance with unfamiliar learning approaches and learning environments. This study proposed a non-immersive virtual reality (VR) guidance system combined with a two-tier strategy to help students learn geology knowledge. Two groups of students used different learning approaches: the experimental group students were guided by the two-tier test VR guidance system, and the control group students learned with the conventional VR guidance system. According to the experimental result, the two-tier test VR guidance system not only improved the students’ learning achievement in natural science, but also enhanced their learning motivation. In addition, according to the sequential results, we found that VR learning materials or environmental resources can help students answer questions and solve problems more effectively.     

Strategies in Teaching English to Large Classes in the Universities

It is widely admitted that teaching English to a large class has certain disadvantages over a small class. But in many schools even universities in China, large class teaching is still a common practice. English teachers in many universities in China often have a lot of teaching difficulties and problems. Therefore, it is necessary for those teachers to understand the main principles and learn Some basic strategies for large class English teaching in order to improve their teaching. This paper aims to suggest some guidelines for large class EFL teachers.     

关于企业会计委派制的思考

实施会计委派制不符合我国社会主义市场经济发展的客观要求 ,其理由 :一是它不符合我国经济体制改革的目标和方向 ;二是它夸大了会计的监督职能 ,不符合市场经济条件下企业对会计的内在要求 ;三是新《会计法》规定单位负责人对会计工作全面负责的同时享有自主用人的权利 ;四是它不是解决会计信息失真的根本问题

Cognitive-enhancing effects of hydrolysate of polygalasaponin in SAMP8 mice

Objectives

The aim of the study is to evaluate the cognitive-enhancing effects of hydrolysate of polygalasaponin (HPS) on senescence accelerate mouse P8 (SAMP8) mice, an effective Alzheimer’s disease (AD) model, and to research the relevant mechanisms.

Methods

The cognitive-enhancing effects of HPS on SAMP8 mice were assessed using Morris water maze (MWM) and step-through passive avoidance tests. Then N-methyl-d-aspartate (NMDA) receptor subunit expression for both the cortex and hippocampus of mice was observed using Western blotting.

Results

HPS (25 and 50 mg/kg) improved the escape rate and decreased the escape latency and time spent in the target quadrant for the SAMP8 mice in the MWM after oral administration of HPS for 10 d. Moreover, it decreased error times in the passive avoidance tests. Western blotting showed that HPS was able to reverse the levels of NMDAR1 and NMDAR2B expression in the cortex or hippocampus of model mice.

Conclusions

The present study suggested that HPS can improve cognitive deficits in SAMP8 mice, and this mechanism might be associated with NMDA receptor (NMDAR)-related pathways.
