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
MOVEMENT EFFICIENCY AND PHYSICAL SELF - IMAGE ACCORDING TO GENDER
Get PDFNamen raziskave je bil ugotoviti, ali obstaja povezanost med gibalno učinkovitostjo in telesno samopodobo glede na spol. V raziskavi je sodelovalo 630 otrok iz severovzhodne Slovenije, starih od 9 do 11 let, od tega je bilo 311 dečkov in 319 deklic. Meritve so potekale na posameznih osnovnih šolah severovzhodne Slovenije. Za ugotavljanje gibalne učinkovitosti je bilo uporabljenih šest testov Eurofit testne baterije ter dodaten test, in sicer hoja nazaj skozi obroče. Podatki o spolu, starosti in telesni samopodobi so bili pridobljeni s pomočjo poslovenjene različice francoske verzije vprašalnika za ugotavljanje telesne samopodobe mladostnikov The Physical Self-Inventory – short form. Za ugotavljanje povezanosti posameznih gibalnih sposobnosti s telesno samopodobo je bila uporabljena regresijska analiza. Statistično značilnost smo ugotavljali na ravni tveganja p ≤ 0,05. Rezultati kažejo, da je koleracija med telesno samopodobo in gibalno učinkovitostjo pri dečkih in deklicah statistično značilna. Pri dečkih na telesno samopodobo najbolj vplivata aerobna vzdržljivost in eksplozivna moč nog. Pri deklicah pa je učinek gibalnih sposobnosti na telesno samopodobo zelo majhen, slednje posvečajo več pozornosti zunanjemu videzu kot gibalnim aktivnostim. Tukaj bi lahko izpostavili, da so deklice v obdobju zgodnje adolescence ravno zaradi hitrejšega zorenja njihovega telesa, v primerjavi z dečki, bolj obremenjene in skrbne glede svoje zunanjosti. Ugotavljamo, da sta gibalna učinkovitost in telesna samopodoba med seboj bolj povezani pri dečkih kot pri deklicah. Slaba gibalna učinkovitost pa je brez dvoma eden od dejavnikov, ki vpliva na nizko telesno samopodobo.The purpose of the research was to determine whether there is a connection between movement efficiency and physical self-image according to gender. There were 630 children from north-eastern Slovenia, aged from 9 to 11 years, included in the research, among which were 311 boys and 319 girls. The measurements took place in individual schools in north-eastern Europe. To determine movement efficiency, six tests of Eurofit Test Battery and an additional test (walking through hoops backwards) were used. The information about the gender, age and physical self-image was gathered with the help of the Slovene version of the French questionnaire for determination of movement efficiency among youth (The Physical Self-Inventory – short form). To determine the correlation of individual motor skills with physical self-image a regression analysis was used. Statistical significance was examined at the risk level of p ≤ 0,05. The results show that the correlation between physical self-image and movement efficiency among boys and girls is statistically significant. The factors influencing the physical self-image of boys the most are aerobic endurance and explosive leg power. The effect of movement competences on physical self-image of girls is very small, since the girls pay more attention to outer appearance than physical activities. It has been determined that movement efficiency and physical self-image are more closely connected in boys than in girls and that low self-image is most certainly influenced by poor movement efficiency
