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
The immunological rehabilitation of patients after lumbar discectomie with BioR
Full text linkCatedra Neurologie USMF „N.Testemiţanu”The clinical study was based upon the analysis of the activity of immunomodulator BioR on the T-limphocities, theier subpopulations, B-limphosities, autoantibodies antidiscus intervertebral, spinel radicula and dura mater in groop of 42 patients with fibrosal lombo-sacral epidurities. In the study have been demonstrated the major eficacity of immunomodulator R in immunoreactivity of umoral and celular human immunity.
Pe un lot de 42 de pacienţi a fost cercetată acţiunea preparatului imunomodulatorului BioR asupra stării indicilor conţinutului limfocitelor T, a subpopulaţiilor lor, limfocitelor B, autoanticorpilor ţesuturilor discului intervertebral, rădăcinei spinale şi dura mater. Este demonstrată eficacitatea mai înaltă a acţiunii imunocorectorului BioR în imunoreactivitatea indicilor schimbaţi ai imunităţii celulare şi umorale. A fost studiat răspunsul imun faţă de un şir de antigene ale microorganismelor pe un lot de 24 pacienţi, care posedă determinante antigenice comune cu ţesuturile umane şi influenţa corectorului imun autohton “BioR” asupra imunoreabilitării modificărilor determinate
Reactivitatea imună şi rezistenţa naturală în caz de radiculopatii lombare discogene
Full text linkAm evaluat starea reactivităţii imune şi rezistenţei naturale a organismului în radiculopatii lombare discogene şi
studierea comparată a acţiunii imunocorectoare a preparatului BioR şi Amniocen. Studiul a inclus 18 bolnavi care au fost supuşi terapiei standard preparatul Amniocen - primul grup (grupul martor), 45 bolnavi cărora li s-a aplicat terapia
standard preparatul BioR - grupul al doilea, grupul al treilea care l-au constituit 21 bolnavi cu radiculopatii lombare
discogene, care nu au necesitat intervenţie operatorie şi cărora li s-a aplicat terapia standard preparatul BioR. Se confirmă dereglarea reactivităţii imune şi a rezistenţei naturale a organismului în caz de această afecţiune. La introducerea în schema de tratament complex a preparatului tisular Amniocen şi a preparatului pe bază de principii active algale BioR, în dinamică se produce normalizarea indicilor imunităţii celulare şi umorale iar, prin rezultatele sale acest studiu prezintă acţiunea imunocorectoare mai concentrată a preparatului BioR asupra indicilor imuni
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
Nivelurile de autoanticorpi, citokine şi caracteristica lor la bolnavii cu radiculopatii lombare discogene sub acţiunea preparatelor BioR şi Amniocen
Full text linkScopul lucrării de a investiga nivelul autoanticorpilor tisulari la pacienţii cu radiculopatii lombare discogene sub
acţiunea preparatelor Amniocen şi BioR. În calitate de antigene au servit: discurile intervertebrale (DI), membrana dură rahidiană (DM), rădăcinile şi nodurile spinale (RN) ale nervilor spinali din zona lombară a măduvei spinării. Studiul nominalizat a inclus 18 bolnavi care au fost supuşi terapiei standard preparatul Amniocen - primul grup (grupul martor), 45
de bolnavi cărora li s-a aplicat terapia standard preparatul BioR - grupul al doilea şi grupul al treilea care l-au constituit 21 de bolnavi cu radiculopatii lombare discogene, care nu au necesitat intervenţie operatorie (chirurgicală) şi cărora li s-a aplicat terapia standard preparatul BioR. La pacienţii din toate grupurile de bolnavi investigate se identifi că dereglări ale nivelurilor autoanticorpilor tisulari
