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
Students\u27 characteristics as factors of cyberbullying and cybervictimization
Get PDFSpletno medvrstniško nasilje je oblika nasilja med vrstniki, ki se dogaja na spletu. Podobno je tradicionalnemu medvrstniškemu nasilju, vendar obstajajo nekatere razlike: spletni nasilnež ni v neposredni bližini spletne žrtve, nasilje preko spleta se širi hitreje in potencialno lahko doseže širše občinstvo, spletno medvrstniško nasilje se lahko izvaja 24 ur dnevno, spletni nasilnež je lahko anonimen. Namen magistrskega dela je bil preučiti dejavnike spletnega medvrstniškega nasilja (spol, starost, šolski uspeh, konstrukte vezane na medvrstniško nasilje, empatijo, izražanje jeze, zaznano oporo s strani vrstnikov, število dobrih prijateljev v razredu, samozaznano priljubljenost, čas aktivne uporabe socialnih omrežij) in ugotoviti, kateri dejavniki in kako napovedujejo izvajanje spletnega medvrstniškega nasilja in spletno viktimizacijo. Vzorec je vključeval 1926 učencev višjih razredov osnovne šole in srednje šole, ki so bili stari med 13 in 20 let. Skupno je sodelovalo 20 osnovnih in srednjih šol iz dveh regij v Sloveniji. Rezultati so pokazali, da so najmočnejši napovedniki izvajanja spletnega medvrstniškega nasilja in spletne viktimizacije konstrukti, vezani na medvrstniško nasilje. Za individualne napovednike izvajanja spletnega medvrstniškega nasilja so se izkazali izvajanje tradicionalnega medvrstniškega nasilja, tradicionalna viktimizacija, spletna viktimizacija, samozaznana priljubljenost in čas aktivne uporabe socialnih omrežij. Za individualna napovednika spletne viktimizacije sta se izkazala tradicionalna viktimizacija in izvajanje spletnega medvrstniškega nasilja. V regresijskem modelu, kjer kot napovednikov izvajanja spletnega medvrstniškega nasilja nismo vnesli konstruktov, vezanih na medvrstniško nasilje, so se za statistično pomembne napovednike izkazale še afektivna empatija, internalizacija jeze, eksternalizacija jeze in zaznana opora s strani vrstnikov. V regresijskem modelu, kjer kot napovednikov spletne viktimizacije nismo vnesli konstruktov, vezanih na medvrstniško nasilje, so se kot statistično pomembni napovedniki izkazali še spol, internalizacija jeze, eksternalizacija jeze, zaznana opora s strani vrstnikov, samozaznana priljubljenost in čas aktivne uporabe socialnih omrežij.Cyberbullying is a type of peer bullying occurring on the internet. It is similar to traditional bullying, however, there are distinct differences between the two forms: the cyberbully is not in the direct vicinity of the cybervictim, cyberbullying spreads faster and can potentially have a wider audience, cyberbullying can occur 24 hours a day and the cyberbully can be anonymous. The purpose of the following master’s thesis was to study the factors of cyberbullying (gender, age, academic achievement, bullying constructs, empathy, anger expression, perceived peer support, number of good friends in the classroom, self-perceived popularity, time of active social media use) and to determine which factors and how predict cyberbullying perpetration and cybervictimization. The sample consisted of 1926 higher grade elementary school students and high school students aged between 13 and 20 years old. In total, 20 elementary schools and high schools from 2 Slovenian regions participated in the study. The results showed that the strongest predictors of cyberbullying perpetration and cybervictimization are bullying constructs. The individual significant predictors of cyberbullying perpetration were shown to be traditional bullying perpetration, traditional victimization, cybervictimization, self-perceived popularity and time of active social media use. The individual significant predictors of cybervictimization were shown to be traditional victimization and cyberbullying perpetration. In the regression model, where we did not include bullying constructs as predictors of cyberbullying perpetration, additional significant predictors were shown to be affective empathy, internalization of anger, externalization of anger and perceived peer support. In the regression model, where we did not include bullying constructs as predictors of cybervictimization, additional significant predictors were shown to be gender, internalization of anger, externalization of anger, perceived peer support, self-perceived popularity and time of active social media use
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
