人类后基因组研究进展

人类对自身基因组的研究不断发展，已从结构基因组学转向功能基因组学阶段。本文概述了人类后基因组的研究内容及进展状况。     

煤矿安全生产与经济发展

现代安全经济学对安全的重要性有一个很好比喻，即“三角形理论”：经济为两条边，安全是一条底边，没有底边的支撑，形成不了这个三角形。经济发展再快，没有安全就构不成稳定的三角形。可见，安全不仅是人类生存的需要，而且是经济发展的前提。一是安全生产保护生产力。生产力3大要素中，人是最具决定性的因素。人类自有生产活动，便存在事故隐患。安全生产的本质是不断消除隐患、遏制事故，保护劳动者的生命安全健康，所以，安全生产始终是保护生产力的一项不可缺少的工作。二是安全生产发展生产力。生产是一种复杂的物质转换活动，活动过程中会遇到各类事故隐患。安全生产通过排治隐患遏制事故，用尽量少的劳动消耗和物质消耗，生产出更多符合社会需要的产品，来促进生产力的发展。     

Global economy gathering strength

Encouraged by a highly expansionary economic policy, the global economy is enjoying a rapid upturn. Utilisation of capacity is high in many sectors, particularly in the growth centres of the USA and East Asia, where China leads the field. With inflationary risks on the increase, most countries are now shifting the focus of economic policy. Fiscal policy in particular can be expected to provide little in the way of further stimulus. In addition, there has been a turnaround in interest rates in many countries. Yet how quickly can the monetary reins be tightened without jeopardising growth or endangering price stability?     

New ways of achieving debt sustainability beyond the enhanced HIPC Initiative

In 1996 the Heavily Indebted Poor Countries (HIPC) Initiative was launched by the Bretton Woods institutions to reduce the external debt burden of low-income countries (LICs) to sustainable levels in a reasonably short period of time because debt constitutes an obstacle to sustainable economic growth and poverty reduction. In some HIPCs, however, debt sustainability has been in danger despite debt relief under the HIPC Initiative. Debt relief is a necessary but not a sufficient condition for development. It can do no more than play a catalytic role. The question, then, is how to achieve debt sustainability beyond the HIPC Initiative.     

城镇社会保障的“本地—外来”分割与外来人口社会保障缺失

过去对城市社会保障缺失的学术关注集中在农民工并从城乡分割来解释。本文认为,在现行的社会保障地方分权体制下,存在着城;市社会保障城的“本地——外来”分割,表现为外来人口,包括外来非农人口的社会保障缺失;社会保障地方分权的背景是城乡和区域发展不平衡。对北京市调查数据的分析显示了社会养老保险参保率的“本地—外来”差异。     

文化背景差异与大学英语听力教学

大学英语听力课教学是英语教学的重要组成部分，教学方法的改革已不能仅仅局限于浅层次上，要针对学生学习过程的难点进行认真的分析研究，找出从根本上解决问题的途径，化背景差异正是中国学生英语听力理解中的难点。
