废物处理与地球物质循环

经减量化后，环境容量所能允许的污染物经地球物质循环，转变成非污染物。本文开拓出了废物处理的一种新视野。     

化学与社会

环境的保护、能源的开发利用、功能材料的研制、生命过程奥秘的探索,是目前国际上最关心的几个重大问题,它们都与化学密切相关.人们的衣、食、住、行,国民经济各个部门,尖端科学技术各个领域,都与化学密不可分.     

稀土离子对α-淀粉酶纤维素酶胰蛋白酶活性的影响

研究了稀土离子(La3+、Sm3+,Y3+)对α-淀粉酶,纤维素酶和胰蛋白酶活性的影响.结果表明稀土离子(La3+,Sm3+,Y3+)对3种酶的活性都具有显著的抑制作用,随着稀土离子用量的增加,其抑制作用增强.同一种稀土金属离子对不同的酶活性的抑制效果不同;不同的稀土离子对同一种酶的抑制效果也不一样.     

Working-class women study social science degrees: remembering enablers and detractors

In this article, we report on a feminist memory work project conducted with 11 working-class women in Australia. Participants responded to the question: what helps and hinders working-class women study social science degrees? The women confirmed that to succeed at university, they needed opportunities, resources, support and encouragement. We called these enablers and considered the role of ‘enlightened witnesses’ [Miller, 1997. The essential role of an enlightened witness in society. Retrieved from http://www.alice-miller.com/index_en.php?page=2]. Hindering the possibility of university success were detractors of many forms including inadequate resources and social conventions that discouraged the women from study. We describe saboteurs as undermining people and forces that the women had to overcome. We found that enlightened witnesses, broadly conceptualised, go some way but not all, to mitigating detractors and saboteurs that continue to hamper fair and meritocratic access to tertiary education.     

软土地基路堤的变形监测与分析

高速公路软土地基路段采用预压等措施处理并通车运行后,通过对纵横断面的变形监测和测量数据分析,该路段在设计年限路面最大沉降量符合规范要求,横断面路拱的横坡变化与车荷载及地基处理措施等因素有关。     

社科期刊专业化、特色化发展路径选择

国内外期刊业对学术期刊专业化水平的要求与期刊分级的制度化给期刊界带来前所未有的机遇与挑战,期刊专业化、特色化发展是高校综合性社会科学学报走出困境的唯一可行道路,为此期刊界人士进行了各种探索。发挥主编办刊的主观能动性,努力实现编辑学者化、专业化转型,整合资源联合办刊、走社会化办刊道路是社科期刊专业化、特色化发展的路径。     

NOAA Environmental Data Management

The United States’ National Oceanic and Atmospheric Administration (NOAA) operates over one hundred observing systems and numerical models providing information and forecasts about the planetary environment from the bottom of the ocean to the surface of the Sun. Collected NOAA data constitute an irreplaceable resource that must be well-documented, discoverable, accessible, and preserved for future use. Good data management should therefore be part of NOAA's core business practices, and employees and leadership should be aware of their roles and responsibilities in this arena. NOAA has developed an Environmental Data Management (EDM) Framework document that discusses Principles, Governance, Resources, Standards, Architecture, Assessment, and the Data Lifecycle, and which also enumerates specific recommendations. The NOAA EDM Committee has issued Directives pertaining to data management planning, archiving, data access, metadata, and other topics. A Data Catalog has been established, and a project to assign persistent, citable identifiers to archival data is well underway. Numerous groups at NOAA are performing technical work related to data access, usability, and preservation.

The purpose of this article is to describe these documents and activities in order to share our experiences and to provide guidance and encouragement for improved data management practices and processes at other organizations.     

再读毛泽东《与天奋斗》诗

毛泽东1917年写的《与天奋斗》诗。曾激励无数人英勇奋斗。但是在“文化大革命”中。“四人帮”曾篡改该诗原意,用来挑起群众斗群众。给一些人理解该诗的真正含义打上了偏见的烙印。本文从“与天”、“与地”、“与人”奋斗的历史内涵和现实意义进行考证和分析。发现该诗既是当时的时代号角,又是对人类“奋斗”不息精神的歌颂。具有永恒的哲理性及艺术上的创新性。     

学习科学研究之发展综述

学习科学是在反思认知科学等学科关于学习的研究方法和观点的基础上新近兴起的一门科学,它借鉴建构主义、认知科学、信息技术、社会文化研究和关于知识工作等相关领域的研究成果,汇集和整合关于脑的研究和内隐学习、非正式学习、正式学习等已有对于学习的研究,采用多种现场研究的方法,对不同情境脉络中的学习发生机制进行分析和探索,提出的若干关于学习的新观点,并通过创新性项目的实践和基于设计的研究,创设新型学习环境,革新学习实践。本文就学习科学兴起的背景、基础、发展历程、主要观点、主要研究方法、国际学术界动向等方面进行了梳理、分析和概括,以期给予国内学者的了解和把握。
