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
ASSOCIATION OF MIGRAINE AND HLA DRB1* ALLELES
No full textSustav HLA najsloženiji je genetski sustav kod čovjeka. Između ostalog, osobitosti ovog
sustava su izraziti polimorfizam, kao i povezanost ovog sustava s bolestima, što je od
izrazite važnosti u dijagnostici autoimunih bolesti kao i neuroloških oboljenja. Migrena je
ponavljajuća, umjereno jaka do vrlo jaka glavobolja u trajanju između 4 i 72 sata u slučaju
kada se ne liječi. Postoji nekoliko čimbenika rizika povezanih s razvojem migrene. U
nepromjenjive čimbenike spadaju genetika, dob i spol.
Cilj je ovog rada odrediti zastupljenost alela sustava HLA u pacijenata kojima je
dijagnosticirana migrena i kod pacijenata koji pate od jakih glavobolja na području Splitskodalmatinske županije kao i prikazati zastupljenost pojedinih alela lokusa HLA - DRB1*.
Kod ispitanika s migrenom i jakim glavoboljama koji su imali HLA-DRB1*16,
zastupljenost spolova pokazuje da je znatno veći postotak oboljelih kod žena (68.96%) u
odnosu na muškarce (31.04%). Najveći broj ispitanika je bio u dobnoj skupini od 46 do 65
godina.
Antigeni i aleli sustava HLA za potrebe ove studije određeni su serološkim i
molekularnim metodama. Antigeni sustava HLA određuju se testom
mikrolimfocitotoksičnosti (MLCT), dok su za molekularno određivanje alela lokusa sustava
HLA korištene metode PCR-SSO i PCR-SSP.
Određivanjem alela lokusa HLA-DRB1 u skupini ispitanika s migrenom, uočeno je 14
različitih alela, od kojih najveću zastupljenost imaju HLA-DRB1*16 (19,59%) te HLADRB1*11,-13,-15 s učestalosti od 10,14%. U usporedbi sa kontrolnom skupinom, utvrđeno
je da je učestalost alela HLA-DRB1*16 (19,59% vs 9,60%, p=0,0063) i HLA-DRB1*10
(2,7% vs 0%, p=0,0327) statističko značajno povećana u skupini pacijenata koji boluju od
migrene ili jake glavobolje.
Budući da su našim ispitanicima u dijagnostičke svrhe određivani i aleli lokusa HLA
razreda I (HLA-A, HLA-B) prilikom analize uočena je statistički značajna povezanost alela
HLA-B*57 kod pacijenata s migrenom i jakim glavoboljama u odnosu na kontrolnu skupinu
zdravih ispitanika.
Da bismo sa sigurnošću govorili o povezanosti migrene i jakih glavobolja i alela HLADRB1*16 i ostalih alela lokusa sustava HLA (HLA-A, HLA-B) svakako je potrebno
proširiti studiju na veći broj ispitanika.The HLA system is the most complex genetic system in humans. Among other things, the
peculiarities of this system are its pronounced polymorphism, as well as the connection of this
system with diseases, which is of great importance in the diagnosis of autoimmune diseases as
well as neurological diseases. Migraine is a recurrent, moderately severe to very severe
headache lasting between 4 and 72 hours if left untreated. There are several risk factors
associated with developing migraines. Immutable factors include genetics, age and gender.
The objective of this work was to determine the representation of alleles of the HLA system in
patients suffering from migraines and severe headaches in the Split-Dalmatia County, as well
as to show the representation of individual alleles of the HLA locus - DRB1*.
In subjects with migraine and severe headaches who had HLA-DRB1*16, the representation of
genders shows that the percentage of patients is significantly higher in women (68.96%)
compared to men (31.04%). The largest number of respondents was in the age group of 46 to
65 years.
Antigens and alleles of the HLA system for the purposes of this study were determined by
serological and molecular methods. Antigens of the HLA system are determined by the
microlymphocytotoxicity test (MLCT), while the PCR-SSO and PCR-SSP were used for the
molecular determination of alleles of the HLA system locus. .
By determining the alleles of the HLA-DRB1 locus in the group of subjects with migraine, 14
different alleles were observed, of which the highest prevalence is HLA-DRB1*16 (19.59%)
and HLA-DRB1*11,-13,-15 with a frequency of 10 , 14%. Compared to the control group, the
frequency of alleles HLA-DRB1*16 (19.59% vs 9.60%, p=0.0063) and HLA-DRB1*10 (2.7%
vs 0%, p =0.0327) statistically significantly increased in the group of patients with migraine or
severe headache.
Since alleles of the HLA class I locus (HLA-A, HLA-B) were also determined for diagnostic
purposes in our subjects, the analysis revealed a statistically significant association of the HLAB*57 allele in patients with migraine and severe headaches compared to the healthy control
group examinee.
In order to talk with certainty about the connection between migraine and severe headaches and
the HLA-DRB1*16 allele and other alleles of the HLA system locus (HLA-A, HLA-B), it is
certainly necessary to expand the study to a larger number of subjects
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
