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
Quality of life clinical rating scales in patients with peptic ulcer disease complicated with perforation

Monitoring and enhancement of a
patient's health-related quality of
life is an important element of
research and medical care.
Purpose
To evaluate the therapeutic
effects and quality of life in
patients treated with different
types of surgical treatment
of perforated ulcer.
Material and methods
We used the validated questionnaires -
GSRS and GIQLI. These scores
represent specific instrument for
gastrointestinal diseases, each rated on
a seven-point Likert scale from which
one represents no discomfort and seven
represents very severe discomfort.
Results
Postoperative overall health was
significantly higher in group with
laparoscopic treatment compared with
preoperative level and comparable with
general population.
Conclusions
Minimally invasive introduction of technology has opened up a new
direction for health related quality of life as comparative analysis between
open and laparoscopic methods without evaluating the quality of life of the
patient will be insufficient

Assessment of the life quality after surgery for perforated gastroduodenal ulcer
Full text linkIntroduction. Quality of life is a cornerstone in the assessment of modern medicine, surgery, and healthcare practices. This aspect is becoming increasingly important in healthcare due to the rapidly increasing power, variety, and cost of
modern drugs and surgical techniques.
The aim of this study was to assess and compare the quality of postoperative recovery in patients undergoing surgery for perforated ulcer.
Material and methods. This observational, prospective study was conducted on
231 patients undergoing emergency surgery. Postoperative recovery was assessed using the GSRS and MOS SF-36. The control group for the studied parameters consisted of average data obtained from 42 healthy individuals from the general population, with similar socioeconomic status and age to the main group of
the study.
Results. The research presents an analysis of 231 patients, mostly men, which is
considered statistically conclusive (p<0.0001), with a diagnosis of perforated gastroduodenal ulcer resolved by various surgical interventions. The majority of the
patients were of working age, highlighting the significant social and economic impact of these issues. The remote follow-up period extended up to 10 years (average 7 years) after the primary surgery. The correlation between the life quality
index and the surgical approach applied was statistically significant (p<0.001). In
the comparative analysis, it was noted that, among all the surgical intervention
methods, the groups undergoing ulcer excision, ulcer excision with vagotomy, and
gastric resection yielded the least favorable results (p<0.001). The data obtained
confirm that the GSRS and MOS SF-36 indices of life quality in patients undergoing
the laparoscopic approach are statistically significantly better and more sustainable, impacting the effectiveness of treatment resolution (p<0.001).
Conclusions. Life quality measures are increasingly used worldwide to assess
surgical outcomes, as they focus on specific health conditions and are essential for
detecting changes resulting from treatment, thereby assessing its effectiveness .
The present study found that the differential selection of treatment tactics using
modern minimally invasive technologies, especially laparoscopic suturing of perforated gastroduodenal ulcer, demonstrated significantly better efficiency compared to traditional, especially radical, operations
