Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
A review on diffuse glioma and gene transfer technologies and the impact of COVID-19 on neurosurgical oncology service provision
Get PDF1) Diffuse glioma is one of the most devastating cancers know in terms of morbidity and mortality. During the last decade, the mortality rate has seen a very modest change. Due to the rapid improvement in understanding the glioma-genesis, evolution, and genetic landscape, a new classification has emerged, improving the diagnostic accuracy. However, the new knowledge acquired has not been translated into novel therapeutic therapies. The treatment regime has mostly relied on maximal surgical resection and chemo/radiotherapy. Nevertheless, gross macroscopic surgical resection is allowing for a significant number of tumour cells to be left behind. Glioma Stem Cells (GSCs) left behind can acquire chemo-resistant properties and exhibit a plethora of characteristics that enable cell survival and growth, leading to an aggressive tumour recurrence. It is now increasingly recognised that IDH mutations are linked to the development of glioma and tumour reoccurrence. IDH mutations can lead to genetic and epigenetic changes promoting cell proliferation, tumour invasion and immune evasion as well as preventing differentiation. Understanding these pathways will allow for new rational therapeutic interventions in an attempt to improve patient outcomes.
2) Gene delivery is the process whereby foreign genomic material is inserted into a host cell or organism. A number of viral and non-viral gene transfer system have been developed in the last few decades. However, no system to date has been used without certain limitations. Here we critically appraise and outline, the advantages, disadvantages, and common uses of viral and non-viral methods.
3) The severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) pandemic brings new challenges to the management of neuro-oncology patients. In the West Midlands (WM) a population of 5.7 million is served by three neuro-oncology centres. NHS service delivery was reconfigured to cope with SARS-CoV-2 infections. Here we report the impact at three centres with low (CLOW), medium (CMED) and high (CHIGH) levels of SARS-COV-2 mortality on referrals and diagnosis, surgical safety and quality and clinical management during the pandemic.
Data were collected either prospectively or retrospectively using electronic clinical records from each centre during period 1 (before lockdown) and period 2 of SARS-CoV-2 (complete lockdown). Referral into specialist care pathways fell by 40% leading to reductions in diagnostic surgery of over 30% as a result of SARS-COV-2 related changes in healthcare provision and help-seeking behaviour. For SARS-COV-2 negative patients, surgical morbidity, 30-day readmission and 30-day mortality were unaffected by changes in management, but operations took longer, and there
was an increase in patients with post-operative residual disease. There were no readmissions with SARS-COV-2 infection within 30 days of surgery. Access to radiotherapy and chemotherapy was reduced with patients suffering from the most aggressive cancers being more severely impacted. Future planning should consider accelerating access to advanced molecular diagnostic technologies to refine clinical decision making and the use of chemotherapy. Regional networking solutions could optimise the use of resources and maintain a higher standard of care, allowing patients to continue to receive the best possible care

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
