Digital archives in the cloud: Collective memory,institutional histories and the politics of information

The archive is a cultural institution that creates a framework for the social and collective memory and as such is one of the collection of knowledge institutions that not only preserves and classifies “texts” but uses them to re-create collective memory and sometimes to invent cultural histories. Like all knowledge institutions, the archive is also a construction deeply implicated in knowledge politics or what Foucault calls power/knowledge. In the past the archive has functioned as a central metaphor for the construction of human knowledge in all it is different institutional forms and like the encyclopedia and the camera, the archive produces highly coded representations that make implicit validity claims to the truth and justice of the past. Politically speaking, those who control the archive control the past. In the digital world, the archive is used to describe a machine-readable location as a store for “data” and “information.” Digital technologies radically alter our existing institutions, making access to their embedded knowledge widely available and enable learning and research anytime, anywhere. Data analytics algorithmically can manipulate electorates and entire democracies in new ways, while destabilising the free press. This article asks what digitizing an archive means for collective memory, for the history of institutions and for politics in the Cloud.     

启动式的广告创意——一种无意识的视点

广告信息的拥塞使我们把目光投向了无意识的广告形式,广告中的无意识现象及近期内隐记忆的研究成果给我们足够的信心去探讨这一广告形式,而要使内隐经验产生作用关键在于启动,为此我们提出了启动式广告这一概念,并在如何启动上作了一些阐述.     

加入WTO后企业改革与发展战略的选择

加入WTO标志着我国的改革开放已进入了一个新的阶段。WTO所追求的是自由市场原则 ,其约束的真正对象是政府 ,它要求政府通过降低关税、取消非关税壁垒和开放服务贸易等措施对外开放市场。随着实力强劲的跨国公司的大举进入 ,我国的企业将面临严峻的挑战。因此 ,我国的企业应选择什么改革与发展战略才能应对激烈的市场竞争是一个十分重要的问题。本文认为 ,关键是要通过技术创新培育我国企业的核心竞争力 ,使企业不仅具有成本优势 ,而且具有技术优势。而企业核心竞争力的培育依赖于企业制度的创新。

阿尔兹海默症患者的语义记忆损伤:表现、理论及展望

图片命名、范畴流畅性等神经心理学测验表明,阿尔兹海默症(AD)患者普遍存在语义记忆的损伤,并随着病程的发展表现出进行性与弥散性特点。AD患者语义记忆的损伤既可能由语义知识的存储障碍造成,也可能由语义知识的提取障碍引发,还可能由存储与提取的双重损伤造成。未来研究应开发出对早期AD检测更为敏感的语义记忆测验,并采用横向与纵向多种研究技术与手段,考虑不同语言文化背景下AD患者语义损伤的情况,以综合分析AD患者语义记忆损伤的实质及其发展趋势。

Fluid reasoning,working memory and planning ability in assessment of risk for mathematical difficulties

ABSTRACT

The demands on mathematical problem-solving have increased in almost all school systems internationally and may constitute a barrier for children with special educational needs (SEN). This study explored the role of fluid reasoning (FR), working memory (WM) and complex executive function of planning (EF) in children (N = 62) referred for assessment of SEN, and specifically of risk for mathematical difficulties (MD). Performances on FR, WM and complex EF of planning were used to predict risk for MD. Results showed that planning ability predicted children at risk for MD, beyond FR or WM ability, when comparing with children not at risk for MD. It was concluded that assessing the complex EF of planning in addition to FR and WM ability is crucial in identifying children at risk for MD. The importance of understanding how planning ability affects children’s mathematical problem-solving is discussed, in relation to assessment and teaching practices.

渐开线少齿差齿轮副承载能力系数

渐开线少齿差齿轮副,由于是内啮合,齿轮副的齿对之间的间隙很小,在受力后轮齿变形而使得同时有多对齿啮合。本文用简明的几何推导,弹性力学的方法,推导出了轮齿受载弹性变形后同时啮合的确切齿对和承受载荷最大的齿对的载荷与总载荷的比例系数——承载能力系数。利用承载能力系数可算出更符合实际的各齿对分别承受的载荷。经样机的设计、制造和试验结果表明,本文提出的计算方法和公式是正确的,可以有效地提高齿轮副的承载能力。
