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
The effect of pandemic on sports habits, physical and mental health of college students
No full textAz utóbbi évek robbanásszerű technológia fejlődés hatására jelentősen
megváltoztott az emberek életvitele, megemelkedett az ülő életmódot folytató
emberek száma, melyet tovább tetézte a Covid–19-pandémia hatása (Ráthonyi
et. al. 2021). A nemkívánatos mellékhatása vagyis a mozgásszegény életmód
számtalan egészséget károsító hatással jár: erek elmeszedése, infarktusveszély,
nagy testsúly, állandósult idegfeszültség, csökkenő munkaképesség. Az egészség érdekében végzett testmozgás, rekreációs edzés célja a testi-lelki felfrissülés, aktív pihenés során az egészség megőrzése és fejlesztése, a tudatos és tervszerű végzése a következő hatásokkal jár: növeli a szív teljesítményét, megnő
az izmokban a mitokondriumok száma, növeli a szív koszorúereinek számát,
növeli az erek átmérőjét, rugalmasságát, csökkenti a vérnyomást, csökkenti a
koleszterinszintet, elősegíti az ideális testsúly megtartását, megfelelő táplálkozással társítva növeli az edzés hatását, megelőzi és gyógyítja a negatív stressz
mértékét (Fritz 2006). A rendszeres fizikai aktivitás és a sport az egészség fenntartásának, prevenciójának alappillére és a stresszoldó hatása a gyakorlatban is
ismert széles körben, csökkenti a depresszív és pszichoszomatikus tünetképzés gyakoriságát (Müller–Bácsné Bába 2018; Petrika 2012). Életünk alapjaiban
okozott változást a járványhelyzet, a távolléti oktatás bevezetésével különleges
helyzet elé állította a testnevelés tantárgy folyamatát és a sporttevékenységek
számos szférájában is éreztette korlátozó hatását (Tokodi et. al. 2022)
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
Physical activity and sports habits of college students

Спорт, подібно до інших звичок здорового способу життя, має зароджене коріння у ранньому дитинстві, тому важливо, щоб у цей період сформувалася любов до фізичних вправ, а діти звикли до регулярної
фізичної активності. Підлітки та молодь становлять ту категорію людей, для якої первинна профілактика
обіцяє найбільший довгостроковий успіх, а зміна шкідливих звичок найбільш можлива саме в цей час. Приблизно половина старшокласників і лише третина студентів закладів вищої освіти займаються спортом
регулярно. Рівень активності зменшується у дорослому віці. Це свідчить про очевидні відмінності у звичках
по відношенню до спорту, враховуючи соціальні фактори. Тому важливо, щоб університетські роки становили можливість для занять спортом у рамках організованої діяльності, консультування з питань здорового
способу життя, впровадження та свідомого усвідомлення профілактичної ролі спорту.Abstract. Sport, like other health behaviours, is linked to early childhood patterns, so it is important to develop a love of
exercise and get children used to regular physical activity. Adolescents and young people are the population for whom
primary prevention has the greatest potential for long-term success and when it is most likely to change harmful
behaviours. Aproximately half of the secondary school students and only one third of those in higher education play
sport regularly. Activity levels fall even further in adulthood. This suggests that there are clear differences in sporting
habits across social background factors. It is therefore important that the university years provide the last opportunity to
practise sport in an organised setting, to provide lifestyle advice and to promote and raise awareness of the preventive
function of sport.
Lack of time, bad experiences and lack of interest were noted as the most influential factors influencing the lack of
sports activities. In these cases, the majority chose these arguments. Overall, the satisfaction results suggest that lack of
personal motivation is the most prominent problem. Regarding the choice of sport, there are differences both in terms
of gender and in the types of athletes, where there is a strong relationship between the types of athletes and the choice
of sport (p=0.009). In the case of women, both types of athletes value cycling more highly, and swimming is a popular
sport to about equal extent. However, there is a difference in the choice of sport among athletes – volleyball and fitness
among athletes, and aerobics among non-athletes are more popular. Among male students, the priorities in choosing a sport differ significantly depending on the type of athlete: football remains popular among athletes, which is connected
with the growing importance of fitness, and basketball is also significant. Among those who do not do sports, the most
popular are swimming and horse riding (18% each).
Recently, the essence of sports needs of students of higher educational institutions has changed. This is caused,
on the one hand, by the motivation of students, and on the other – by changes in opportunities. When planning sports
services and leisure programs, it is necessary to take into account the new needs of the younger generation, the changed
worldview and changes in the requirements for the place and conditions of sports
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
