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
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

Diagnostic and prognostic markers in canine inflammatory and neoplastic head and neck conditions
Get PDFSeveral different types of conditions with inflammatory and neoplastic background affect the anatomical localities of the head and neck in a dog. It is a well-recognized fact that these conditions affect the quality of life, as they are associated with various degree of regional dysfunction, have systemic effects and can be direct or indirect cause of death. Unfortunately, many dogs with both inflammatory and neoplastic head and neck conditions are presented at an advanced stage of the disease which can have significant impact on treatment strategies. The identification of biomarkers is advisable to enhance effective staging, grading and prognostication, which will in turn more accurately direct recommendations for therapy.
These biomarkers can theoretically help to distinguish between inflammatory and neoplastic conditions, justify the management of patients more accurately and potentially predict the prognosis and the survival of patients.
It was our interest to investigate the diagnostic and prognostic value of complete blood count parameters and indices in dogs with head and neck conditions of inflammatory and neoplastic origin, regulatory T cells in dogs with periodontal disease, immunohistochemical (Ki-67 and VEGFR-2) and histopathological biomarkers in dogs with inflammatory and neoplastic head and neck conditions and to evaluate the effectiveness of an accelerated radiotherapy protocol for the treatment of advanced canine HNSCC.
We have proved that the parameters investigated might serve as important supportive diagnostic and/or prognostic biomarkers which might help to improve the treatment strategies of both inflammatory and neoplastic head and neck conditions in dogs and that the accelerated chemoradiotherapy protocol represents an effective alternative treatment option for dogs with advanced HNSCC
Concentration and fluid intelligence in relation to motor skills in fifth graders
No full textŠtevilo raziskav, ki preučujejo povezovanje motorike in psiholoških značilnosti, narašča, a vseeno je na tem področju še vedno precej neodgovorjenih vprašanj. Predvsem pri otrocih, ki so v fazi dinamičnega razvoja, je dobro razumevanje tega odnosa bistveno za oblikovanje smiselnih in učinkovitih priporočil telesne vadbe, ki se glede na pretekle raziskave pozitivno povezuje z razvojem kognicije. Podatki v dani magistrski nalogi so bili zbrani v sklopu projekta SLOfit, preko katerega se že od leta 1996 sistematično spremlja telesni in gibalni razvoj slovenskih otrok in mladostnikov. Projektu je bilo v nekaterih 5. razredih ljubljanskih osnovnih šol leta 2021 pilotno dodano še kognitivno testiranje, in sicer Test pozornosti d2 ter Test nizov, ki meri fluidno inteligentnost. V našo raziskavo je bilo vključenih 281 otrok, od tega 154 dečkov in 127 deklic. Poleg omenjenih kognitivnih testov smo uporabili še podatke motoričnih nalog športnovzgojnega kartona, podrobneje naloge, ki merijo vzdržljivost, eksplozivnost in koordinacijo. Zanimala nas je povezava motoričnih sposobnosti vzdržljivosti in koordinacije s koncentracijo ter motoričnih sposobnosti eksplozivnosti in koordinacije s fluidno inteligentnostjo. Na danem vzorcu se niso pokazale enoznačne pomembne povezave med koncentracijo, fluidno inteligentnostjo in motoričnimi pokazatelji, z izjemo pri deklicah, kjer rezultati kažejo na manjšo, a pomembno povezavo med mero fluidne inteligentnosti ter motoričnimi nalogami eksplozivnosti in koordinacije. Nekatere manjše, a pomembne povezave psiholoških spremenljivk so se pokazale tudi pri nalogah, za katere je potrebna koordinacija. Koordinativni elementi vadbe se potencialno povezujejo s kognicijo, vendar so zaradi kompleksnosti področja, majhnih učinkov ter relativno majhnega in starostno homogenega vzorca na tem področju potrebne dodatne raziskave.The number of studies examining the connection between motor skills and psychological characteristics is growing, but there are still many unanswered questions in this area. Especially for children who are in a phase of dynamic development, a good understanding of this relationship is essential for formulating meaningful and effective recommendations for physical exercise, which, according to past research, is positively associated with the development of cognition. The data in this master\u27s thesis were collected as part of the SLOfit project, through which the physical development of Slovenian children and adolescents has been systematically monitored since 1996. In 2021, cognitive testing was added to the project for the first time in some elementary schools (5th grade) in Ljubljana, namely the d2 attention test and “Test nizov”, which measures fluid intelligence. 281 children were included in our research, of which 154 were boys and 127 were girls. In addition to the mentioned cognitive tests, we also used the data of the SLOfit project motor tasks, more specifically the tasks that measure endurance, explosiveness, and coordination. We were interested in the connection of motor skills of endurance and coordination with concentration and motor skills of explosiveness and coordination with fluid intelligence. No unambiguous significant correlations between concentration, fluid intelligence, and motor skills were found in the given sample. Some small but significant correlations were found between fluid intelligence and motor tasks based in explosiveness and coordination in girls. Additionally, small but significant correlations were found between psychological variables and motor tasks requiring coordination. Coordinative elements of exercise are potentially associated with cognition, but due to the complexity of the area, low correlations, and relatively small and age-homogeneous sample, additional research is needed
