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

hematološkim brojačima predstavlja prvi korak u analizi DKS-a periferne krvi. U slučaju prisutnosti patoloških
stanica i stanica s morfološkim abnormalnostima, analizator daje upozorenje o patološkom nalazu što upućuje na
potrebu izrade DKS-a svjetlosnom mikroskopijom i/ili digitalnom morfološkom analizom. Bez obzira na
tehnološki napredak, izrada DKS-a svjetlosnom mikroskopijom i dalje predstavlja zlatni standard. Međutim,
prednost primjene uređaja za digitalnu morfologiju je ušteda vremena uz visoku preciznost i točnost. Cilj ovog
diplomskog rada bio je ispitati i usporediti preciznost izrade DKS-a metodom svjetlosne mikroskopije i digitalne
morfološke analize (postupak preklasifikacije i klasifikacije) u razmazima periferne krvi sa i bez patologije,
primjenom uređaja Sysmex DI-60. Ukupno je analizirano sedam razmaza periferne krvi: tri razmaza rutinskih
uzoraka u kojima je ispitana preciznost svjetlosne mikroskopije i digitalne morfološke analize, te četiri razmaza iz
programa vanjske procjene kvalitete u kojima je ispitana preciznost digitalne morfološke analize. Temeljem
dobivenih rezultata potvrđena je hipoteza o većoj preciznosti digitalne morfološke analize u odnosu na metodu
svjetlosne mikroskopije. Iznimka su bili patološki razmazi s akutnim leukemijama u kojima se metoda svjetlosne
mikroskopije pokazala preciznijom u brojenju patoloških, nezrelih stanica periferne krvi. Nadalje, preciznost
dobivena postupkom klasifikacije na uređaju Sysmex DI-60 nije uvijek bila veća u odnosu na postupak
preklasifikacije zbog nejasno definiranih morfoloških kriterija i subjektivnosti u njihovoj procjeni. Također, u
postupku preklasifikacije na uređaju Sysmex DI-60, uočen je veći udio neidentificiranih stanica u patološkim
razmazima periferne krvi u odnosu na razmaze bez patologije, što potvrđuje nužnost primjene svjetlosne
mikroskopije u takvim slučajevima. Najmanja preciznost uočena je za nesegmentirane granulocite za sve tri
metode i za ponovljivost i za međupreciznost u razmazima sa i bez patologije.Preparation of a differential blood count (DBC) is commonly carried out using three methods: automated analysis
on hematology analyzers, light microscopy, and digital morphological cell analysis. Performing a DBC on
hematology analyzers is the first step in the analysis of peripheral blood DBC. In the presence of pathological cells
and cells with morphological abnormalities, the analyser provides a warning indicating a pathological finding,
suggesting the need for DBC analysis using light microscopy and/or digital morphological analysis. Despite
technological advancements, DBC performed using light microscopy remains the gold standard. However, the
advantage of using digital morphology analyzers lies in time savings, along with high precision and accuracy. The
aim of this thesis was to examine and compare the precision of DBC performed by light microscopy and digital
morphological analysis (reclassification and classification processes) on peripheral blood smears with and without
pathology, using the Sysmex DI-60 analyzer. A total of seven peripheral blood smears were analyzed: three smears
of routine samples in which the precision of light microscopy and digital morphological analysis was examined,
and four smears from the external quality assessment program in which the precision of digital morphological
analysis was assessed. Based on the obtained results, the hypothesis of greater precision of digital morphological
analysis compared to the light microscopy method was confirmed. Exceptions were pathological smears with acute
leukemias, in which light microscopy proved to be more precise in counting pathological, immature peripheral
blood cells. Furthermore, the precision obtained by the classification process on the Sysmex DI-60 analyzer was
not always higher compared to the reclassification process, due to poorly defined morphological criteria and
subjectivity in their assessment. Additionally, in the reclassification process on the Sysmex DI-60 analyzer, a
higher proportion of unidentified cells was observed in pathological peripheral blood smears compared to nonpathological
smears, confirming the necessity of using light microscopy in such cases. The lowest precision was
observed for non-segmented granulocytes across all three methods, for both repeatability and intermediate
precision, in smears with and without pathology

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
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
