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
Indications for using proper type of prosthesis in elderly patients with femoral neck fractures
Get PDFDepartment of Traumatology
and Orthopedics,
Nicolae Testemitanu State University of Medicine and Pharmacy of the Republic of MoldovaIntroduction. Femoral neck fractures in the elderly are frequent due to the increase in life
expectancy. These injuries represent a great health care problem and have a significant impact on
health insurance costs. Hip replacement for this kind of fractures is a common and safe
procedure, which will allow to mobilize patients shortly after surgery. Types of endoprosthesis
used in elderly include unipolar, bipolar hemiarthroplasty, or total hip arthroplasty. Over ¾ of
cases occur after the age of 60, with the main predisposing factor being osteoporosis, so a minor
trauma involving an accidental fall is sufficient to produce a fracture. In young people, to
produce such a fracture, a much stronger impact is required.
Aim of the study. Summarizing of indications and contraindication of using a certain type of
prosthesis for the treatment of the femoral neck fractures in elderly patients.
Materials and methods. For the study were used the materials collected in the 2nd Department
of the PMSI Clinical Hospital for Orthopedics and Traumatology during the 2012-2017 period,
that included data of 464 elderly patients with femoral neck fracture. The main focus was: the
Garden classification of the fracture, age of the patient, their general condition, osteoporosis and
osteoarthritis degrees.
Results. In 2nd department were hospitalized patients with Garden III and IV type of the femoral
neck fracture. Unipolar prosthesis was used in 171 cases (36.9%), only in patients over 80 years;
bipolar hemiarthroplasty in 192 cases (41.5%), age variation was of 60 - 80 years; also a total hip
arthroplasty was selected for 101 (21.6%) patients with advanced degrees of osteoarthritis. In our study, unipolar hemiarthroplasty was used for the patients who are physiologically older with
comorbidities. They were satisfied after surgery, being able to perform their daily activity.
Advantages of monopolar and bipolar arthroplasties include short operation time and quick
mobilization of the patient, which is very good to prevent complications. Disadvantages of
unipolar and bipolar hemiarthroplasty is that they increase biomechanical stresses on the
acetabulum with consecutive destruction of the acetabular fosa with developing of cotiloidites.
The appearance of cotiloiditis may require surgical re-intervention and conversion to the total hip
prosthesis. 85% were patients over 70 years of age, respectively the prostheses used were mostly
bipolar and monopolar, but there were also those who required total prosthesis. Total hip
replacement is advantageous for active, healthy, lucid patients, with a long life expectancy.
Conclusions. The discussions of using total hip arthroplasty vs monopolar or bipolar
hemiarthroplasty are still open. Total hip replacement seems to be preferred for avoiding surgical
re-intervention with possible patient risks and additional costs. Also these aspects should be
evaluated to avoid the risks of prolonged and invasive surgical intervention occurring in total hip
arthroplasty
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

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.
