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
Importanța indicatorilor de performanță în activitatea spitalicească
Full text linkBackground. Key performance indicators play an essential role in enhancement of management in
medical institutions. The knowledge and proper use of indicators offers the possibility to increase the
quality in providing medical services. Objective of the study. Identification and analysis of the most
important indicators in order to evaluate, control and monitor the performance of hospital
activity. Material and Methods. For study realization were used medical sources - international and
local literature, statistics, scientific publications and individual researches. For data analysis was used
the tool -STROBE Strengthening the Reporting of Observation Studies in Epidemiology, applied on
studies: cohort, case-control and cross-sectional. Results. Were analyzed approx 20 studies and 50
articles with reference to the topic. After analyzing the data 22 performance indicators were selected
and classified under four aspects: Internal Process - 10 ( Mortality rate; proportion of cancelled
operations; Hospital infection rate; frequency of clinical errors; etc.) Finance -5 (Ratio of total revenue
to total costs; the cost of drugs and materials; proportion personnel costs of total costs; etc.) Learning
and Growth - 4 (Training expenditures per capita; Employee absenteeism rate; etc.) Patient - 3 (Level
of facilities for families and visitors; Patients satisfaction percentage etc.). Conclusion. The model of
studied indicators can be used for the performance assessment in hospitals and allows to recognize
critical points cost efficiency of institution (SWOT analysis). This model can be adjusted according to
hospital profile.
Introducere. Indicatorii de performanță joacă un rol esențial în eficientizarea managementului
spitalicesc. Cunoașterea și utilizarea eficace a indicatorilor oferă posibilitatea de a spori calitatea
prestării serviciilor medicale. Scopul lucrării. Identificarea și analiza celor mai importanți indicatori
care asigură evaluarea, controlul și monitorizarea performanței activității spitalicești. Material și
Metode. Pentru realizarea studiului s-au utilizat surse de specialitate medicală - literatura internațională
și autohtonă, date statistice, publicații științifice și cercetări individuale. Pentru analiza datelor s-a folosit
instrumentul - STROBE Strengthening the Reporting of Observation Studies in Epidemiology utilizat
în studii de tip: cohortă, caz-control și transversale. Rezultate. Au fost analizate circa 20 de studii și 50
de articole cu referire la temă. În urma analizei datelor, 22 de indicatori de performanță au fost selectați
și clasificați sub patru aspecte: procesul intern – 10 (letalitatea spitalicească, proporția intervențiilor
anulate, frecvența erorilor clinice etc.); finanțe – 5 (raportul venituri totale/costuri totale, costul
medicamentelor și al materialelor, proporția remunerării personalului din costurile totale etc.); studiu și
dezvoltare – 4 (costul instruirii personalului per capita, rata absenteismului angajaților etc.); pacientul –
3 (rata facilităților pentru familie și vizitatori, proporția satisfacției pacienților;
etc.). Concluzii. Modelul indicatorilor studiat poate fi utilizat în evaluarea performanței instituțiilor
medicale și în identificarea punctelor slabe și a cost eficienței instituției (analiza SWOT). Prin urmare
modelul poate fi ajustat în funcție de profilul spitalului
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
Characteristics of patients with TB/ HIV coinfection
Full text linkUniversitatea de Stat de Medicină şi Farmacie „Nicolae Testemiţanu”, Chişinău, Republica MoldovaIntroducere. Potrivit datelor OMS persoanele care trăiesc cu HIV dezvoltă tuberculoza de 19 (15-22) ori mai des decât cei neinfectați. La nivel global în anul 2019 au decedat 208.000 TB/HIV din 1,4 mln decese de TB, iar în anul 2020 au decedat 214.000 și au contribuit la creșterea mortalității până la 1,5 mln. Scopul lucrării. Caracteristica bolnavilor cu coinfecția TB/HIV aflați la tratament în staționarul municipal de tuberculoză. Material și Metode. Studiul retrospectiv, selectiv, descriptiv. Datele anamnestice, clinice și paraclinice au fost prelevate din fișele medicale a 74 bolnavi aflați în staționar în perioada anilor 2018-2020. Rezultate. Repartizarea după sex: bărbați au fost 49, femei – 25. A predominat vârsta între 35-44 ani (46%) urmată de 25-34 ani (20,3 %) și 45-54 ani (19 %). După tipul de caz au fost: cazuri noi – 47 (63,5%), recidive – 12 (16,3%), pierduți din supraveghere – 10(13,5%), eșec terapeutic- 5(6,7%). Forma infiltrativă de tuberculoză s-a înregistrat la 49 (66,2%), diseminată- la 21 (28,3%) și fibro-cavitară – la 4 (5,5%) bolnavi. Confirmarea microbiologică a fost stabilită la 40 (54,1%), iar rezultat negativ – la 34 (45,9%). Micobacteriile de tuberculoză au fost sensibile către preparatele antituberculoase la 29 (72,5%) și rezistente – la 11 (27,5%) cazuri. Concluzii. La bolnavii cu coinfecția TB/HIV tratați în staționar predomină vârsta tânără, cazurile noi, formele extinse de tuberculoză, o jumătate din ei erau baciliferi, iar rezistența micobacteriilor de tuberculoză s-a constat la 1/3 din bolnavi.Background. According to WHO data, people living with HIV develop tuberculosis 19 (15-22) times more often than those who are not infected. Globally, in 2019, 208,000 TB/ HIV died out of 1.4 million TB deaths, and in 2020, 214,000 died and contributed to the increase in mortality to 1.5 million. Objective of the study. Characteristics of patients with TB/HIV coinfection undergoing treatment in the municipal tuberculosis hospital. Material and Methods. Retrospective, selective, and selective study. Anamnestic, clinical and paraclinical data were taken from the medical records of 74 patients in hospital during the years 2018-2020. Results. Distribution by sex: men were 49, women – 25. The predominant age was 35-44 years (46%) followed by 25-34 years (20.3%) and 45-54 years (19%). By type of case were: new cases – 47 (63.5%), relapses – 12 (16.3%), lost supervision – 10 (13.5%), therapeutic failure – 5 (6.7%). The infiltrative form of tuberculosis was registered in 49 (66.2%), disseminated – in 21 (28.3%) and fibrous-cavernous – in 4 (5.5%) patients. The microbiological confirmation was set at 40 (54.1%) and the negative result at 34 (45.9%). Tuberculosis mycobacteria were sensitive to antituberculosis drugs in 29 (72.5%) and resistant – in 11 (27.5%) cases. Conclusion. In patients with TB/HIV coinfection treated in inpatient care, young age predominates, new cases, widespread forms of tuberculosis, half of them were bacilli, and the resistance of mycobacteria to tuberculosis was found in 1/3 of patients

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
