A randomised controlled trial: comparing nurse-led with standard care for post-acute medical patients
No full textThis study was carried out in the context of increased pressure on acute medical beds, increasing demand for alternatives to acute medical care and the need to reduce junior doctors' working hours. Nurse-led in-patient care has been advocated as a response to these pressures that also has the potential to improve patient outcomes. However, evidence to support the safety and effectiveness of this model of care was limited and came from Nursing Development Units, making it difficult to predict how well the model of care would perform in routine NHS practice. The nurse-led in-patient service was compared with standard care on the acute wards via a randomised controlled trial. Recruitment for the trial took 17.5 months. Key outcomes were length of stay following randomisation, discharge destination and change in physical functioning. Secondary outcomes were mortality, re-admissions within thirty days of discharge, falls, complications of hospitalisation. The process of care was explored by comparing medical reviews, therapy reviews, changes to medication and numbers of tests and investigations during the trial period. The nurse-led service did not demonstrate any improvement in outcomes, but substantially increased the length of stay in the treatment arm of the trial. The apparently higher rate of therapy reviews and rates of some complications were diminished when these outcomes were controlled for length of stay. Daily rates of medical reviews, medical investigations and changes to medications were lower for the treatment arm of the trial. The findings of this study do not support the limited benefit reported in previous studies. The widespread introduction of this model of care cannot, therefore, be advocated on the basis of improved outcomes for post-acute patients. However, the nurse-led intervention was not shown to be worse than standard care and may result in organisational benefits, such as reduced medical input. From the poor outcomes observed in this study, it would appear that neither nurse-led nor standard care is meeting the needs of this patient group. Further research is needed to identify and evaluate appropriate nursing interventions for post-acute medical patients
Tm:glass fiber laser pumping Ho:YAG and Ho:LuAG
No full textContinuous Ho:YAG and HorLuAG lasers were pumped by a laser diode pumped Tm:glass fiber. Slope efficiencies achieved were comparable with the product of the fraction of the pump power absorbed and the quantum defect. This laser combines several important ingredients including: beam shaping of the laser diode bars for efficient coupling to the Tm:glass fiber, double clad fiber providing good pump absorption and beam quality, fiber laser output tunable to a Ho absorption peak, and long upper laser level lifetime in a laser material containing only Ho, thus minimizing any detrimental up conversion
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
