In September 2000, new qualifications for 16–19 year olds, known as Curriculum 2000, were introduced in England, Wales, and Northern Ireland with the aim of broadening the advanced level curriculum. It was left to schools, colleges, and their learners, however, to decide how these new qualifications would be used to build learner programmes of study. In this voluntarist context, the views and actions of learners have been an important factor in determining the course of the reforms. This article, which is based primarily on a study of 42 learners in a school/college consortium in the south west of England, provides a chronological account of learner experiences of these reforms during their first 2 years of implementation. The consortium discussed here offered a high‐volume study programme similar in size and content to those being proposed by the Tomlinson Working Group on 14–19 curriculum and qualifications reform in England. Learners found their expanded programmes onerous, due in part to the nature of the new qualifications and in part to the context of their implementation. The article concludes by identifying a number of policy lessons for 14–19 reform arising from this research.  相似文献

IntroductionThe data on the coronavirus disease (COVID-19) in solid-organ transplant recipients (SOTRs) in Croatia is unknown. The aim of this study was to analyze the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Croatian SOTRs.Materials and methodsFrom 7 September to 27 November 2020 (beginning of the second COVID-19 pandemic wave), a cross-sectional screening for COVID-19 was performed in the adult outpatient liver (LTRs; N = 280) and kidney transplant recipients (KTRs; N = 232). Serum samples were initially tested for SARS-CoV-2 IgG antibodies using a commercial enzyme-linked immunosorbent assay (ELISA; Vircell Microbiologists, Granada, Spain). All positive samples were confirmed using a virus neutralization test (VNT). Data on risk exposure and COVID-19 related symptoms were collected using a questionnaire.ResultsThe transplanted cohort’s seroprevalence detected by ELISA and VNT was 20.1% and 3.1%, respectively. Neutralizing (NT) antibodies developed in 15.6% of anti-SARS-CoV-2 ELISA IgG positive SOTRs. The difference in seropositivity rates between LTRs and KTRs was not statistically significant (ELISA 21.1% vs. 19.0%, P = 0.554; VNT 3.6% vs. 2.6%, P = 0.082). Overall VNT positivity rates were higher in patients who reported participation in large community events (5.9% vs. 1.0%; P = 0.027) as well as in patients who reported COVID-19 related symptoms in the past six months. In addition, symptomatic VNT positive patients showed significantly higher (P = 0.031) NT antibody titers (median 128, interquartile range (IQR) = 32-128) compared to asymptomatic patients (median 16, IQR = 16-48).ConclusionsThis study showed that 15.6% of anti-SARS-CoV-2 ELISA positive Croatian SOTRs developed NT antibodies indicating protective immunity. Further studies are needed to determine the dynamic of NT antibodies and COVID-19 immunity duration in immunocompromised populations such as LTRs and KTRs.  相似文献

Artificial intelligence (AI) is playing a key supporting role in the fight against COVID-19 and perhaps will contribute to solutions quicker than we would otherwise achieve in many fields and applications. Since the outbreak of the pandemic, there has been an upsurge in the exploration and use of AI, and other data analytic tools, in a multitude of areas. This paper addresses some of the many considerations for managing the development and deployment of AI applications, including planning; unpredictable, unexpected, or biased results; repurposing; the importance of data; and diversity in AI team membership. We provide implications for research and for practice, according to each of the considerations. Finally we conclude that we need to plan and carefully consider the issues associated with the development and use of AI as we look for quick solutions.  相似文献

Various technology innovations and applications have been developed to fight the coronavirus pandemic. The pandemic also has implications for the design, development, and use of technologies. There is an urgent need for a greater understanding of what roles information systems and technology researchers can play in this global pandemic. This paper examines emerging technologies used to mitigate the threats of COVID-19 and relevant challenges related to technology design, development, and use. It also provides insights and suggestions into how information systems and technology scholars can help fight the COVID-19 pandemic. This paper helps promote future research and technology development to produce better solutions for tackling the COVID-19 pandemic and future pandemics.  相似文献

实证表明新冠肺炎疫情下公众选择不同传播渠道产生的"自我卷入"程度不一:短视频、微博(或微信)、新闻类APP等移动新传播渠道给公众造成的恐惧感更为显著;电视(或广播)等传统渠道更能影响公众的应急反应,让公众主动采取防护措施,积极进行自我保护和积极应对;但公众在权威信息、疫情进展上对电视(或广播)等传统渠道的期望值更高。主流媒体应从把控信息源头、创新表达形式、布局好舆情监测机制、做好媒体议程设置等四个方面来提高自身公信力,提高公众对主流信息的"自我卷入"程度,以防范可能出现的"信息疫情",维护社会秩序健康稳定。  相似文献
