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
Wymierne korzyści z redukcji masy ciała w terapii otyłości — badania własne
Full text linkIntroduction. Obesity is a serious health problem of the twenty-first century. The number
of patients steadily increased and efforts to reduce body weight rarely bear fruit. The basis
of obesity therapy is to obtain through low-energy diet and physical activity, a negative energy
balance. The aim of this study was to determine the effects of a 3-month diet 1500 kcal on
selected anthropometric and biochemical parameters in patients with obesity.
Material and methods. The study included 23 patients of Clinic of Hypertension and Metabolic
Disorders in Poznan, including 18 women and 5 men. All patients made anthropometric measurements
— body weight, height, BMI, waist circumference, hip circumference and marked
biochemical parameters — glucose, triglycerides, total cholesterol, LDL and HDL. Patients were
on a 3-month balanced 1500 kcal diet. After that time again rated the test parameters.
Results. Patients had elevated values of selected anthropometric and biochemical parameters.
3-month diet 1500 kcal reduction resulted in a decrease in weight, thereby changing
the value of the BMI. A decline of waist and hip circumference were reported. Among the
biochemical parameters some were significantly reduced: the concentration of glucose, total
cholesterol, LDL cholesterol and triglycerides.
Conclusions. Obese patients are characterized by elevated values of anthropometric parameters
and selected biochemical parameters. 1500 kcal low-energy diet causes weight loss
in obese patients. Reducing balanced diet helps lower blood glucose and lipid profile modification.Wstęp. Otyłość stanowi poważny problem zdrowotny XXI wieku. Liczba chorych systematycznie
wzrasta, a działania podejmowane w celu redukcji masy ciała rzadko przynoszą
efekty. Podstawą terapii otyłości jest uzyskanie za pomocą diety ubogoenergetycznej oraz
aktywności fizycznej, ujemnego bilansu energetycznego. Celem pracy było określenie
wpływu 3-miesięcznej diety 1500 kcal na wybrane parametry antropometryczne oraz biochemiczne
u chorych z otyłością.
Materiał i metody. Do badania zakwalifikowano 23 pacjentów Poradni Nadciśnienia Tętniczego
i Zaburzeń Metabolicznych w Poznaniu, w tym 18 kobiet i 5 mężczyzn. U wszystkich
chorych dokonano pomiarów antropometrycznych — masa ciała, wzrost, wskaźnik
BMI, obwód talii, obwód bioder oraz oznaczono parametry biochemiczne — stężenie glukozy,
triglicerydów, cholesterolu całkowitego, LDL i HDL. Pacjentów poddano 3-miesięcznej
zbilansowanej diecie redukcyjnej 1500 kcal. Po tym czasie ponownie oceniono badane
parametry.
Wyniki. U pacjentów stwierdzono podwyższone wartości parametrów antropometrycznych
oraz wybranych parametrów biochemicznych. Trzymiesięczna dieta redukcyjna 1500 kcal
spowodowała spadek masy ciała, zmieniając tym samym wartość wskaźnika BMI. Zmniejszył
się obwód talii oraz obwód bioder. Wśród parametrów biochemicznych istotnie statystycznie
uległy redukcji: stężenie glukozy, cholesterolu całkowitego, cholesterolu LDL oraz
triglicerydów.
Wnioski. Otyli pacjenci charakteryzują się podwyższonymi wartościami parametrów antropometrycznych
oraz wybranych parametrów biochemicznych, a dieta ubogoenergetyczna
1500 kcal powoduje utratę masy ciała u otyłych chorych. W badaniu dowiedziono,
że zbilansowana dieta redukcyjna wpływa na obniżenie stężenia glukozy oraz
parametrów gospodarki lipidowej
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
