Humankind is facing its worst pandemic of the twenty-first century, due to infection of a novel coronavirus named as SARS-CoV2, started from Wuhan in China. Till now, 15 million people are infected, causing more than 600,000 deaths. The disease, commonly known as, COVID-19, was initially thought to be associated with ARDS only, but later on revealed to have many unexplained and atypical clinical features like coagulopathy and cytokinemia, leading to multi-organ involvements. The patients also suffer from ‘Silent Hypoxemia’, where there is no immediate respiratory signs and symptoms even though alarmingly low SpO2 level. We hypothesize that this covert hypoxemia may lead to molecular changes exacerbating coagulopathy and cytokine storm in COVID19 patients, which again, in turn, causes a vicious cycle of more hypoxemia/hypoxia and progression of the infection to more severe stages through HIF-1α dependent pathway. Although molecular mechanisms are yet to be substantiated by scientific evidence, hypoxemia remains an independent worsening factor in serious COVID 19 patients. Keeping all in mind, we propose that even in the early and asymptomatic cases, prophylactic oxygen therapy to be initiated to break the vicious cycle and to reduce the mortality in COVID 19 to save precious human lives. 相似文献

ABSTRACTGraduate employability is a key issue for higher education as new graduates face a highly competitive and rapidly changing employment sector. To maximise their likelihood of employment, graduates need to be able to demonstrate the skills and attributes most valued by employers. Employers, however, have long criticised the ability of graduates to contribute effectively to the workplace, especially due to a perceived lack of generic employability skills. This indicates a possible mismatch between the skills required by employers and those possessed by graduate applicants. This study addresses a gap in the scholarly literature regarding employability skills – the perspectives of science academics at an Australian and UK university regarding the promotion of generic employability skills in the subjects they teach. More specifically, this article discusses academics’ perspectives regarding: (a) which of the targeted generic skills were developed and assessed through their science units, and (b) the approaches used to promote the targeted skills and any associated challenges in employing those approaches. The discussion explores how shifting from traditional transmissive pedagogies to more problem-based approaches and embedding reflection into pedagogy and assessment practices would contribute to promoting the skills employers increasingly demand from science graduates. 相似文献

With digitisation and the rise of e‐learning have come a range of computational tools and approaches that have allowed educators to better support the learners' experience in schools, colleges and universities. The move away from traditional paper‐based course materials, registration, admissions and support services to the mobile, always‐on and always accessible data has driven demand for information and generated new forms of data observable through consumption behaviours. These changes have led to a plethora of data sets that store learning content and track user behaviours. Most recently, new data analytics approaches are creating new ways of understanding trends and behaviours in students that can be used to improve learning design, strengthen student retention, provide early warning signals concerning individual students and help to personalise the learner's experience. This paper proposes a foundational learning analytics model (LAM) for higher education that focuses on the dynamic interaction of stakeholders with their data supported by visual analytics, such as self‐organising maps, to generate conversations, shared inquiry and solution‐seeking. The model can be applied for other educational institutions interested in using learning analytics processes to support personalised learning and support services. Further work is testing its efficacy in increasing student retention rates. 相似文献

The sample mean is sometimes depicted as a fulcrum placed under the Dot plot. We provide an alternative geometric visualization of the sample mean using the empirical cumulative distribution function or the cumulative histogram data. 相似文献

Psychological resilience is important in sport because athletes must constantly withstand a wide range of pressures to attain and sustain high performance. To advance psychologists’ understanding of this area, there exists an urgent need to develop a sport-specific measure of resilience. The purpose of this article is to review psychometric issues in resilience research and to discuss the implications for sport psychology. Drawing on the wider general psychology literature to inform the discussion, the narrative is divided into three main sections relating to resilience and its assessment: adversity, positive adaptation, and protective factors. The first section reviews the different ways that adversity has been measured and considers the potential problems of using items with varying degrees of controllability and risk. The second section discusses the different approaches to assessing positive adaptation and examines the issue of circularity pervasive in resilience research. The final section explores the various issues related to the assessment of protective factors drawing directly from current measures of resilience in other psychology sub-disciplines. The commentary concludes with key recommendations for sport psychology researchers seeking to develop a measure of psychological resilience in athletes. 相似文献

In the nineteenth century, Alfred Russel Wallace was generally acknowledged as one of the founders of evolutionary theory.
But, during the twentieth century, his contributions came to be neglected as Darwin worship often replaced cogent historical
assessment. This is a story worth studying. It shows how scientific advances are often simultaneously made by many different
individuals working independently; these advances are as much products of their intellectual context as they are of individual
genius or inspiration. The story also shows the power of social background and privilege within science (how Darwin managed
to avoid being pre-empted by Wallace), how scientists compete for priority, and how future generations co-opt history to suit
their own purposes. 相似文献
