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
Гигиена полости рта в рамках первичной, вторичной и третичной профилактики одонто-пародонтальных заболеваний

Periodontal affection in the context of chronic human diseases
Get PDFCatedra de stomatologie terapeutică USMF „Nicolae Testemiţanu”Periodontitis is generally considered to be the consequence of offenses host – parasite,
where the bacteria are determinants of disease. Distribution of periodontopathic bacteria is much
wider than periodontitis distribution, which fact indicates that the association of bacteria -
periodontitis is weak. This paper proposes a model for generalised periodontitis, where the host
factors are not the only triggers, but they are also personal factors that influence the relationship
outcome host – parasite. Personal factors that reduce host defense effectiveness may include
psychosocial srtess, factors related to lifestyle (diet, smoking, alcoholism) and systemic factors
as (intercurrent diseases or immune/inflammatory system deficiencies).
Parodontita este în general considerată a fi consecinţa unei interacţiuni nefavorabile gazdă
– parazit, în care bacteriile sînt determinanţii bolii. Distribuţia bacteriilor periodontopatice este
mult mai largă decît distribuţia parodontitei, ceia ce indică că asocierea bacterie – parodontită
este slabă. Această lucrare propune un model pentru parodontita generalizată, în care factorii
gazdă nu sînt singurii declanşatori, ci sînt şi factorii personali ce influenţează rezultatul relaţiei
gazdă – parazit. Factorii personali ce diminuează eficienţa apărării gazdei pot include stresul
psihosocial, factorii legaţi de stilul de viaţă (alimentaţia, fumatul, alcoolismul) şi factorii
sistemici ca (bolile intercurente sau dificienţele sictemului imun/inflamator)
The remarks of paradontal changes in influence of personal factors of risk in pregnancy period
Get PDFCatedra Stomatologie terapeutică USMF „Nicolae Testemiţanu”The parodontal disease in incipient or advanced stage for near all people have a long history. A similar situation is for pregnant woman. It is important to mention that in this state, the personal factors of risk(smoke, stress) are diminishing the efficiency of host protection. In this work is praised the clinical picture of parodontal changes in pregnancy period in influence of factors enumerated and the correlation between them.
Boala parodontală, în stadii precoce sau avansate, la aproape toate persoanele are o istorie atât de lungă, cât a omului însuşi. Situaţie similară este şi la femeile gravide. Important este de menţionat faptul, că în această stare factorii personali de risc (stressul, fumatul, antecedentele heredo – colaterale ş. a.) diminuează şi mai mult eficienţa apărării gazdei. În lucrare se evidenţiază tabloul clinic actual al modificărilor parodontale în perioada de sarcină sub influenţa factorilor enumeraţi mai sus şi corelaţia dintre ei
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
