This article considers the role of the SENCo during Covid-19 pandemic conditions of school lockdown with partial reopening for children classified as ‘vulnerable’. It is argued that the existing pressures and tensions already experienced by SENCos – for example, related to time, workload, status, and their prescribed managerial and strategic role – have been highlighted by pandemic conditions. Pressures resulting specifically from the pandemic are reflected by considering how SENCos will adjust to enact their role during this time. It is concluded that an advocacy role for pupils with special educational needs and disability, who are at risk of becoming increasingly marginalised within school and wider communities during this pandemic, should now be considered a central element of the SENCo’s remit. 相似文献

The emerging creative practices of digital collections are increasing in prominence thanks to the access to, and appeal of, data visualizations. Interactive data visualizations, such as a map, timeline, chart, graph, or artist’s rendering of data, enable users to pursue their own research interests within a collection and participate in new areas of research. Use of these data visualizations enhances the scope of the collection and enables a modern and diverse thematic collection to emerge. This article considers the question: Does the addition of data visualizations affect how users participate with a research collection? Impacts on collection development, application of user-centered design, and analysis of users’ exploratory strategies are discussed. Examples of data visualizations used in digital humanities projects and digital collections are presented as case studies. 相似文献

In recent years, a small but growing body of scholarship has emerged on the category of the Chinese art district, particularly its institutionalisation amidst twenty-first century creative industries polices. Such research presents important stories of Chinese artists’ negotiations with urban and political authority, thus nuancing paradigms for the comprehension of political work within contemporary China. This current article contributes to this growing research area by considering the spatial conditions for these socio-spatial categories’ emergence, namely, the urban structures in which they first took shape in 1990s Beijing. First occupying traditional villages (cunzi) and later ex-socialist work units (danwei), these arts colonies appropriated existing communal architecture, and turned their designs and physical buildings to their own communal ends. Importantly, these sites were made available by the dramatic reconstruction of the city, and in this sense these occupations were limited to the temporal realm. To describe the nature of occupations, and their eventual impact upon the shape of the city, this paper proposes the category of “the temporal pocket”: a cellular and temporary inhabitance, defined by the shared investments of its participants, and one that is both discrete (in the sense of its spaces) and discreet (in the sense that this can be understood as a non-oppositional politics). The article is informed by spatial and cultural theory, literature on Chinese urban planning and art history, as well as primary documents (such as documentaries, art works and archival material) and interviews conducted by the researcher in Beijing. 相似文献

Based on a survey of Chinese publicly traded firms, we report on the status of the strategic information systems planning success in China. Through this analysis of the survey data, we found that Chinese managers are not using IS as a competitive weapon though they have already realized some aspects of strategic information system planning. We also examined the differences between Eastern and Western cultural and political context factors to explain this phenomenon. 相似文献

Baseline data available on the excretory profiles of estrone giucuronide (E1G), pregnanediol glucuronide (PdG) and luteinising hormone (LH) on human menstrual cycles (n=104) was retrospectively analysed
for identifying the limits of fertile period (FP) to be used as natural method of family planning. The limits of fertile period
are suggested based on centile distribution of E1G and PdG levels during defined phase of menstrual cycle. Two approaches, which do not involve any mathematical calculation
are suggested. In approach A, fertile period is said to have started when E1G value of 35 ng/ml is reached and is said to have ended when the PdG value of 2 μg/ml on two consecutive days is obtained.
The criteria were applied to 30 test cycles in whom authentic fertile period was identified based on excretory profiles of
E1G, PdG and LH throughout the menstrual cycles. When approach A was followed the authentic fertile period was covered in 27
cycles giving an accuracy of 90% with a mean fertile period length of 9.11+1.9 days. In approach B, the cut off limit of E1G value was increased to 55 ng/ml in order to reduce the days of abstinence. Though the length of the fertile period was reduced
to 7.2+1.5 days the accuracy of the approach was 66.6%. Thus the approach A which has accuracy of 90% may appeal to determined
couples who wish to practice family planning by periodic abstinence or restrict the use of barrier methods. 相似文献
