Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Heart rate variability as an indicator of sport success: a case study of an elite canoe slalom athlete
No full textNamen magistrskega dela je bil raziskati vpliv različnih dejavnikov na variabilnost srčne frekvence (ang. heart rate variability, HRV) in ugotoviti ali je HRV lahko pokazatelj športne uspešnosti v slalomu na divjih vodah. Metode: v longitudinalni študiji primera, ki je potekala med novembrom 2018 in decembrom 2022, je sodelovala vrhunska kajakašica. Meritve HRV so bile izvedene s pomočjo aplikacije na telefonu (HRV4Training) v ležečem položaju, vsako jutro po bujenju in pred vstajanjem. Ob tem smo beležili kakovost in dolžino spanja, zapoznelo mišično bolečino, bolezen, poškodbe, menstrualni cikel in trenažno obremenitev. Analizirali smo rezultate štirih tekmovalnih sezon in izračunali indeks uspešnosti. Za statistično analizo smo uporabili metodo linearnega mešanega modela. Rezultati: v povezavi z rMSSD smo ugotovili statistično pomemben vpliv kakovosti spanja (p 0,5) niso statistično značilno vplivali na rMSSD. Ugotovili smo, da rMSSD (p = 0.823) in rMSSD trend (p = 0.704) nista statistično značilna napovednika indeksa uspešnosti. Zaključek: v skladu z obstoječimi raziskavami smo potrdili vpliv kakovosti spanja in menstrualnega cikla na HRV. Čeprav nismo dokazali statistično značilne povezave med HRV in športno uspešnostjo, izsledki raziskave nakazujejo na morebitno korist simpatične prevlade v predtekmovalnem obdobju v slalomu na divjih vodah.The purpose of this study was to analyse the effect of different variables on heart rate variability (HRV) and to evaluate the role of HRV as a potencial indicator of sports sucess in canoe slalom. Methods: An elite female kayaker participated in a longitudinal case study conducted between November 2018 and December 2022. HRV measurements were conducted with the application on the phone (HRV4Training), each morning after waking up and before getting out of bed, in a supine position. Quality and duration of sleep, delayed muscle soreness, illness, injuries, menstrual cycle and training load were monitored daily. Results of four competitive seasons were analysed and performance index was calculated for each competion result. A linear mixed model method was used for statistical analysis. Results: in relation to rMSSD, a statistically significant influence of sleep quality (p 0.5) have no statistically significant effect on rMSSD. rMSSD (p = 0.823) and rMSSD trend (p = 0.704) were not found to be statistically significant predictors of the performance index. Conclusion: in accordance with existing research, our study confirmed the effect of sleep quality and menstrual cycle on HRV. Although the research did not demonstrate a statistically significant relationship between HRV and sports performance, the findings suggest a possible benefit of sympathetic dominance in the pre-competition period in canoe slalom
Combining Analogue and Digital Techniques: Optimal Interaction Experience for Customers in Online Shopping
Full text linkSpletna komunikacija in interakcija se je čez desetletja, stoletja in obdobja močno spreminjala. Že v zadnji polovici stoletja zaznavamo konkretne spremembe pri načinih in taktikah spletnega komuniciranja, ki so jih povzročile (tehnološke) revolucije, inovacije in nova orodja (tudi spletne) komunikacije. Skozi delo spoznavamo pomen spletne komunikacije in interakcije danes (v primerjavi s preteklostjo), kako le ta vpliva na nakupne navade, kaj prinaša in kje še vedno ostaja ključnega pomena ter zakaj. Na analizi primera spletne trgovine in raziskavi glasbene panoge v Sloveniji ugotavljamo, kaj so tiste taktike, ki povečujejo prodajo in učinkovitost spletnih mest, hkrati pa z njimi vzporedno poteka tudi raziskovanje razlogov za takšne rezultate. Preko naloge sledimo raziskavi in spoznavamo analogne ter digitalne tehnike, s katerimi operirajo oziroma s katerimi bi lahko operirali spletni trgovci. Polje študija bo tudi uporabniška izkušnja, ki je med nami precej dlje, kot je bil opravljen prvi spletni nakup, napovedi pa so precej zložne in ocenjujejo, da bo le ta nekoč postala ena izmed pomembnejših disciplin svetovne ekonomije.Online communication and interaction has changed dramatically over the decades, centuries and eras. Already in the last half of the century, we have seen concrete changes in the approaches and tactics of online communication caused by (technological) revolutions, innovations and new tools of communications (including online). Throughout this MA thesis, we learn about the importance of online communication and interaction today (compared to the past), how it affects buying habits, what it brings, and where and why it remains crucial. Analysing the case of an e-commerce, and researching the music industry in Slovenia, we find out what are the tactics that increase the sales and effectiveness of websites, while simultaneously exploring the reasons for such results. Through this MA thesis, we follow the research and get to know the analogue and digital techniques that are or could be used by online merchants. The field of study is also user experience, which is among us much longer than the first online purchase, because experts agree and predict that it will become one of the major disciplines of the world economy
