模因论观照下的企业网站翻译质量评估原则探讨

模因论认为模因的生命周期可划分为同化、记忆、表达、传输四个阶段,并且成功的模因具有保真度、多产性和长久性三个特点。对于企业网站翻译来说,其实质就是把原语网站模因转换为译语网站模因,并把它们顺利传达给国外客户的过程。这一过程中所涉及的网站模因有显性模因和隐性模因之分,从企业网站功能的角度出发,显性模因的翻译质量评估应该遵循准确、简洁、灵活的原则,隐性模因则要力求规范、重点突出、美观。     

What makes learners a good fit for hybrid learning? Learning competences as predictors of experience and satisfaction in hybrid learning space

Compared with fully face-to-face or online learning environments, implementation of hybrid learning spaces is costly given the spaces making all learning options available for learners. Therefore, decisions on investments in hybrid learning are critical for institutions. Satisfaction and experience of learners is one of the important indicators for assessing the cost-effectiveness of learning space implementation; thus, predictions of learners' satisfaction and experience can inform institutions' decision making on learning space investments. Moreover, learning competences are found correlated with learners' satisfaction and experience in general and e-learning settings. Therefore, the present study aimed at exploring predictive learning competences for hybrid learners' experience and satisfaction. A hybrid learning space was built upon a proposed model at Shanghai Open University. 211 students’ learning competences and their satisfaction and experience in the hybrid learning space were examined. The results showed that except cognitive engagement competence, most predictive competences were not significantly associated with hybrid learners' satisfaction and experience. The findings indicated that since hybrid learning keeps all options available, to experience satisfying learning, students need not have certain competences but cognitive engagement competence, which is correlated with learners' cognitive ability to figure out the right mix of learning options.

Is right ventricular mid-septal pacing superior to apical pacing in patients with high degree atrio-ventricular block and moderately depressed left ventricular function?

Objective

We are aimed to investigate whether right ventricular mid-septal pacing (RVMSP) is superior to conventional right ventricular apical pacing (RVAP) in improving clinical functional capacity and left ventricular ejection fraction (LVEF) for patients with high-degree atrio-ventricular block and moderately depressed left ventricle (LV) function.

Methods

Ninety-two patients with high-degree atrio-ventricular block and moderately reduced LVEF (ranging from 35% to 50%) were randomly allocated to RVMSP (n=45) and RVAP (n=47). New York Heart Association (NYHA) functional class, echocardiographic LVEF, and distance during a 6-min walk test (6MWT) were determined at 18 months after pacemaker implantation. Serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured using an enzyme-linked immunosorbent assay (ELISA) kit.

Results

Compared with baseline, NYHA functional class remained unchanged at 18 months, distance during 6MWT (485 m vs. 517 m) and LVEF (36.7% vs. 41.8%) were increased, but BNP levels were reduced (2352 pg/ml vs. 710 pg/ml) in the RVMSP group compared with those in the RVAP group, especially in patients with LVEF 35%–40% (for all comparisons, P<0.05). However, clinical function capacity and LV function measurements were not significantly changed in patients with RVAP, despite the pacing measurements being similar in both groups, such as R-wave amplitude and capture threshold.

Conclusions

RVMSP provides a better clinical utility, compared with RVAP, in patients with high-degree atrioventricular block and moderately depressed LV function whose LVEF levels ranged from 35% to 40%.

基于能值和DEA的中国城市新陈代谢效率分析

本文运用能值理论及数据包络分析方法(DEA)系统研究了2010年和2000年中国31个案例城市的新陈代谢效率特征及发展机制。结果显示,中西部城市的非可再生资源能值占系统能值总量的比例较高;而上海、北京、深圳等经济发达城市则以进出口能值为主要构成成分。2010年上海、北京、广州、深圳、沈阳、西安、杭州和海口8个案例城市达到新陈代谢效率的DEA有效,其它23个非DEA有效的城市中,绝大多数的非可再生资源投入冗余率、废弃物投入冗余率和出口改善率有待提高。此外,对城市新陈代谢效率的机制分析表明,产业结构、城市化、经济发展和人口集聚要素对于城市新陈代谢效率具有较为显著的正面影响,未来应有的放矢地从以上方面调控城市新陈代谢效率。
