有缺憾方显珍贵

你是否花费时间为"自我完善"而忙碌、而忧虑?如果是这样,可要注意,不要为了随处可见的"完美"而扼杀了自己的个性.用下面这个故事证明我的观点. 　　……     

缅甸的海运科技教育

缅甸海地区具有东南亚典型的渔业资源,若开和德林达依海岸是珍珠文化发展理想场所,沿岸区域盛产出口石油和天然气．如果具备相应的专家技术与管理,从海运范围划分出去的渔业资源将会在未来扮演很重要的角色．缅甸海运科学与技术教育发展的主要目的是：充分利用资源,改进海运交通网络结构和达到海运安全、海运环境保护和安全方面的全球化标准．描述不同部门的不同机构处理的海事事务及其责任．2002年8月1日建校的缅甸海事大学是专门为海事交通部门培训胜任的造船师与工程师的学校．缅甸海事大学为了建设高效的海事团体将进行更广泛的国际合作．     

Getting mobile right: start with who and why,not what and how

Mobile dominance is imminent. Getting mobile wrong means losing market share to disruptors; getting it right gives us an opportunity to rebuild relationships with our audience. It is the audience, therefore, that should direct mobile strategy. This means starting by researching the workflows and challenges of different segments, to understand how to add value (not just bells‐and‐whistles). We must prioritize mobile in our product development and innovation, freeing it from the ‘print + online’ paradigm so that it can fulfil different kinds of information needs and objectives. This article advocates a back‐to‐basics approach that puts audiences (not content, and not technology) at the centre of mobile strategy, and explores market segmentation and research, innovation, business models, development choices, and the wider organizational implications of getting mobile right.     

Estimates of the number of people in England who attain or exceed vigorous intensity exercise by walking at 3 mph

Abstract

Walking is a safe, accessible and low cost activity, amenable to change and known to have great potential to increase physical activity levels in sedentary individuals. The objective of this study is to estimate the proportion of the 2009 adult population of England who would attain or exceed vigorous intensity activity (>70% maximum heart rate [HR_max]) by walking at 3 mph. We conducted predictive impact modelling using participants' (n = 1741, aged 25–64 years) cardiovascular fitness data from treadmill walking tests. We combined this data with English population estimates adjusted for age and sex to estimate the numbers of individuals that would exceed 70% HR_max (an intensity considered sufficient for fitness gains) when walking at 3 mph (4.8 km · h^?1). We estimate 1.5 million men (95% confidence interval [CI] 0.9–2.2 million) (from 13.4 million corresponding to 11.6% (95% CI 7.0–16.2%)) and 3.9 million women (95% CI 3.0–4.8 million) (from 13.6 million corresponding to 28.6% (95% CI 22.0–35.1%)) in England aged 25–64 years would benefit from regularly walking at 3 mph. In total, a projected 5.4 million individuals (95% CI 3.9–6.9 million) aged 25–64 (from 26.97 million corresponding to 20.1% (95% CI 14.6–25.7%)) could benefit from walking at 3 mph. Our estimates suggest a considerable number of individuals in the English population could receive fitness and health benefits by walking regularly at 3 mph. Physical activity messages that promote walking at this speed may therefore have the potential to significantly impact national fitness levels and health in England.     

Mesenchymal stem cells as therapeutic agents and in gene delivery for the treatment of glioma

Mesenchymal stem cells (MSCs) are plastic-adherent cells with a characteristic surface phenotype and properties of self-renewal, differentiation, and high proliferative potential. The characteristics of MSCs and their tumortropic capability make them an ideal tool for use in cell-based therapies for cancer, including glioma. These cells can function either through a bystander effect or as a delivery system for genes and drugs. MSCs have been demonstrated to inhibit the growth of glioma and to improve survival following transplantation into the brain. We briefly review the current data regarding the use of MSCs in the treatment of glioma and discuss the potential strategies for development of a more specific and effective therapy.     

Paradise lost at San Francisco state

Editor's Note: From time to time,Academic Questions, under the heading “Voces Academicae,” publishes interviews with teachers and scholars whose experiences and reflections provide a telling commentary on the nature of contemporary university life. In this interview four faculty members at San Francisco State University discuss the great strike of 1968 and its continuing impact on the life of their institution.
