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

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.
