Environment and Policy Factors Shaping Global E-Commerce Diffusion: A Cross-Country Comparison

This article examines the key global, environmental and policy factors that act as determinants of e-commerce diffusion. It is based on systematic comparison of case studies from 10 countries--Brazil, China, Denmark, France, Germany, Mexico, Japan, Singapore, Taiwan, and the United States. It finds that B2B e-commerce seems to be driven by global forces, whereas B2C seems to be more of a local phenomenon. A preliminary explanation for this difference is that B2B is driven by global competition and MNCs that "push" e-commerce to their global suppliers, customers, and subsidiaries. This in turn creates pressures on local companies to adopt e-commerce to stay competitive. In contrast, B2C is "pulled" by consumer markets, which are mainly local and therefore divergent. While all consumers desire convenience and low prices, consumer preferences and values, national culture, and distribution systems differ markedly across countries and define differences in local consumer markets. These findings support the transformation perspective about globalization and its impacts. In terms of policy, the case studies suggest that enabling policies such as trade and telecommunications liberalization are likely to have the biggest impact on e-commerce, by making ICT and Internet access more affordable to firms and consumers, and increasing pressure on firms to adopt e-commerce to compete. Specific e-commerce legislation appears not to have as big an impact, although inadequate protection for both buyers and sellers in some countries suggests that mechanisms need to be developed to ensure greater confidence in doing business online.

只要发一半的传单--17岁男孩Jason的故事

去年放暑假的时候,我想筹钱买个新耳机,除了自己的积蓄之外还有一些钱要靠做临时工来挣.我找到了一份帮别人发传单的工作.听上去很简单,就是骑着自行车按照公司指定的路线去发,几个小时后再和别人换班.但我报到时还是吓了一跳--很厚的一沓传单,看起来两个人用一天时间也发不完,别说我一个新人了.走出办公室时我觉得心烦透了,再说天气很热,先前的积极性降了一大半.

Redefining ‘early career’ in academia: a collective narrative approach

‘Early career’ in academia is typically defined in terms of research capability in the five years following PhD completion, with career progression from post-doctoral appointment to tenure, promotion and beyond. This ideal path assumes steady employment and continuous research development. With academic work increasingly casualised, experiences of ‘early career’ are changing and definitions in use by institutions and research bodies do not reflect the lived experiences of early career academics (ECAs). This paper presents five collective narratives and a thematic analysis of survey data from 522 ECAs in three Australian universities. The results offer insights into the diverse experiences of the early stages of academic careers and provide an opportunity to reconsider current definitions. We argue that the employment context in higher education makes it crucial to consider scholars’ self-definitions alongside existing objective indicators to redefine early career in academia.     

Seeking optimal confusion: a review on epistemic emotion management in interactive digital learning environments

Emotions play a significant part in students’ learning experiences within complex educational environments. However, the impact of emotional experiences on effective learning is not straightforward. For example, being confused during learning may be perceived as an adverse event. There is, however, considerable research evidence suggesting that confusion can also be a productive aspect of a student's learning processes. Despite this, research also suggests that when confusion is persistent it can become harmful, promoting learner frustration or boredom. Key challenges for the design of interactive digital learning environments (IDLEs) are to detect and assess students’ emotions and to tailor the environment accordingly. In this paper we examine, from a review of the literature, the implications of learners’ confusion that can occur in IDLEs. Strategies for managing students’ confusion will then be discussed and examples of features enhancing learning in IDLEs will be suggested.     

Spine biomechanics associated with the shortened,modern one-plane golf swing

The purpose of this study was to compare kinetic, kinematic, and performance variables associated with full and shortened modern backswings in a skilled group of modern swing (one-plane) golfers. Shortening the modern golf backswing is proposed to reduce vertebral spine stress, but supporting evidence is lacking and performance implications are unknown. Thirteen male golfers performed ten swings of each swing type using their own 7-iron club. Biomechanical-dependent variables included the X-Factor kinematic data and spine kinetics. Performance-related dependent variables included club head velocity (CHV), shot distance, and accuracy (distance from the target line). Data were analysed with repeated measures ANOVA with an a priori alpha of 0.05 (SPSS 22.0, IBM, Armonk, NY, USA). We found significant reductions for the X-Factor (p < 0.05) between the full and shortened swings. The shortened swing condition ameliorated vertebral compression force from 7.6 ± 1.4 to 7.0 ± 1.7 N (normalised to body weight, p = 0.01) and significantly reduced CHV (p < 0.05) by ~2 m/s with concomitant shot distance diminution by ~10 m (p < 0.05). Further research is necessary to examine the applicability of a shortened swing for golfers with low back pain.
