A method of measuring a library's capability for providing the documents its users need has been developed. The library is tested with a representative sample of such documents to determine how long would be required for users to obtain these documents. Test results are expressed in terms of a Capability Index, which has a maximal value of 100 only if all the sample documents are found "on shelf." Specific tests employing samples of 300 documents have been developed that are appropriate for academic and for "reservoir" biomedical libraries. Realistic field trials have demonstrated that these two tests are practical to administer and that test results are adequately reproducible. When strict comparability is not important, a library can test itself. In assessing a reservoir library, test results are supplemented by data on its typical processing time for interlibrary loan requests. Currently these tests are being used in a national survey. The general method is applicable to other types of libraries, provided appropriate test samples are established. If their limitations are clearly understood, these "Document Delivery Tests" can be valuable tools for planning and managing library services. 相似文献

Cataloging and classification provide intellectual access for organizing resources in libraries. In New Zealand, bibliographic control is largely through the application of Library of Congress Subject Headings (LCSH). LCSH provide a sense of context and order. In Indigenous frameworks this sense of order can be found in the link between epistemology and knowledge structure. This article argues that the development and application of Māori subject headings is directly related to the natural order that is pivotal to a Māori worldview. The impact of this worldview and its associated values are explored in the context of the construction of Ngā ūpoko Tukutuku. 相似文献

Delayed diagnosis and treatment of extreme hypertriglyceridemia due to rejection of a lipemic sample
Jan Van Elslande Samira Hijjit Katrien De Vusser Michel Langlois Bjrn Meijers Ann Mertens Bart Van der Schueren Glynis Frans Pieter Vermeersch 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2021,31(2)
IntroductionMost laboratories routinely determine haemolysis, icterus and lipemia indices to identify lipemic samples and reject potentially affected results. Hypertriglyceridemia is the most common cause of lipemia and severe hypertriglyceridemia (≥ 11.3 mmol/L) is a major risk factor of acute pancreatitis.Laboratory analysisA 56-year-old woman attended the outpatient clinic for a follow-up visit 1 month after a kidney transplantation. Her immunosuppressive therapy consisted of corticosteroids, cyclosporine, and mycophenolic acid. The routine clinical chemistry sample was rejected due to extreme lipemia. The comment “extreme lipemic sample” was added on the report, but the requesting physician could not be reached. The Cobas 8000 gave a technical error (absorption > 3.3) for the HIL-indices (L-index: 38.6 mmol/L) which persisted after high-speed centrifugation. The patient was given a new appointment 2 days later. The new sample was also grossly lipemic and gave the same technical error (L-index: 35.9 mmol/L).What happenedThe second sample was manually diluted 20-fold after centrifugation to obtain a result for triglycerides within the measuring range (0.10–50.0 mmol/L). Triglycerides were 169.1 mmol/L, corresponding to very severe hypertriglyceridemia. This result was communicated to the nephrologist and the patient immediately recalled to the hospital. She received therapeutic plasma exchange the next day and did not develop acute pancreatitis.Main lessonThis case illustrates the delicate balance between avoiding the release of unreliable results due to lipemia and the risk of delayed diagnosis when results are rejected. Providing an estimate of the degree of hypertriglyceridemia might be preferable to rejecting the result. 相似文献

Scotland, traditionally, has high levels of confidence in teachers. Fairness and justice are key concepts in policy and practice in Scottish education. For more than 100 years, the high-stakes assessment system in Scotland, with the Scottish Higher qualification at its heart, has been crucial to that sense of opportunity and justice. However, in 2019–2020, public confidence in high-stakes assessment in Scotland, as in other United Kingdom countries, was dented. In Scotland, the Covid-19 pandemic meant that schools were closed, teachers provided online learning opportunities for pupils working at home and, for the first time in 130 years, it was not possible to run national examinations. To ensure that learners were not further disadvantaged, alternative approaches to gathering evidence for qualifications were instigated. However, these results were challenged as socially unjust and the results that had been nationally moderated were replaced by results based on locally moderated teachers' professional judgement. As Scotland looks to qualifications beyond Covid-19, trust must be re-built. This article reports on a participative research project that sought to understand public perceptions of standards and fairness across a range of key communities following this experience. Drawing on both qualitative and quantitative data, we analyse factors which affected trust in National Qualifications under the pandemic. The evidence suggests that when considering what matters for qualifications to be trusted, technocratic solutions are likely to be rejected by stakeholders. Understanding and responding to what led to the mistrust of qualifications in Scotland will be crucial to inform its future qualifications system. 相似文献

In this article we examine the effectiveness of consent in data protection legislation. We argue that the current legal framework for consent, which has its basis in the idea of autonomous authorisation, does not work in practice. In practice the legal requirements for consent lead to ‘consent desensitisation’, undermining privacy protection and trust in data processing. In particular we argue that stricter legal requirements for giving and obtaining consent (explicit consent) as proposed in the European Data protection regulation will further weaken the effectiveness of the consent mechanism. Building on Miller and Wertheimer’s ‘Fair Transaction’ model of consent we will examine alternatives to explicit consent. 相似文献
