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
Sambandet mellan träningsmängd och prestation inom konståkning : En korrelationsstudie på svenska konståkare
No full textSyfte Syftet med arbetet var att undersöka sambandet mellan träningsmängd och prestation för svenska konståkare i A- och Nationella serien inom klasserna junior och senior. Det arbetet syftat till att ta reda på var följande frågeställningar: Finns det något samband mellan det totala antalet träningstimmar per vecka och uppnådd poäng på tävling? Finns det något samband mellan isträningstimmar per vecka och uppnådd poäng på tävling? Finns det något samband mellan fysträningstimmar per vecka och uppnådd poäng på tävling? Hur väl kan den totala träningsmängden förklara den uppnådda poängen på tävling? Metod Data samlades in med hjälp av en webbenkät skapad i Sunet Survey. Frågorna i enkäten handlade om tävlingsklass, total träningsmängd per vecka, totalt antal istimmar per vecka, totalt antal fystimmar per vecka, annan idrott och eventuell skada. Enkäterna mejlades ut till de 120 klubbarna i Sverige med åkare i urvalsgruppen. De statistiska testerna genomfördes i programmet Jamovi där Pearsons sambandsanalys användes för att undersöka sambanden. Utifrån r-värdet kunde även determinationskoefficienten (r2) beräknas genom att ta kvadratroten av korrelationskoefficienten (r). Den valda signifikansnivån för analysen var 0,05. Resultat Totalt samlades 73 enkäter in varvid 66 inkluderades i studiens slutgiltiga analys. Resultatet från de statistiska testerna visade inget samband mellan total träningsmängd och uppnådd poäng på tävling (p=0,097), mängden isträning och uppnådd poäng på tävling (p=0,094) eller mängden fysträning och uppnådd poäng på tävling (p=0,088). 4,2 procent av den uppnådda poängen kunde förklaras av den totala träningsmängden (r2 = 0,042). Slutsats Resultaten från studien visar att det inte finns något samband mellan total träningsmängd och uppnådd poäng på tävling. Tränare som avser förbättra prestationen hos sina åkare bör överväga att reducera mängden träning med tanke på skaderisken och i stället se över träningens innehåll. Det tycks således vara andra faktorer än träningsmängden som är avgörande för prestation hos konståkare på A- och Nationell serienivå. Aim The aim of this study was to research the relationship between training load and performance for Swedish figure skaters in the A- and National series within the junior and senior category. The study aims to research the following questions: Is there any relationship between the total amount of training hours per week and achieved score at competition? Is there any relationship between the amount of training hours on ice per week and achieved score at competition? Is there any relationship between the amount of training hours off ice per week and achieved score at competition? How well can the total training load explain the achieved score at competition? Method Data was collected using a web survey created in Sunet Survey. The questions in the survey focused on competition level, total training hours per week, total training hours on ice per week, total training hours off-ice per week, other sports and possible injury. The surveys were emailed to 120 clubs in Sweden with skaters in the sample group. The statistical tests were completed in the program Jamovi and Person’s correlation analysis was used to study the relationships. Based on the r-value the coefficient of determination (r2) could be calculated by taking the square root of the correlation coefficient (r). The chosen significance level for the analysis was 0,05. Results In total 73 surveys were collected and 66 of them was included in the study’s final analysis. The results from the statistical tests showed no relationship between total training load and achieved score at competition (p=0,097), the amount of ice training and achieved score at competition (p=0,094) or the amount of off-ice training and achieved score at competition (p=0,088). 4,2 percent of the achieved score at competition could be explained by the total training load (r2 = 0,042). Conclusion The results from this study shows that there is no relationship between total training load and achieved score at competition. Coaches aiming to enhance performance for their skaters should consider reducing the training load considering the risk of injury and instead focus on the training content. It seems to be other factors than training load that are crucial for performance for figure skaters at A- and National series level.
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
