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
Młodzież w cyberczasoprzestrzeni – zagrożenia i szanse
No full textThe article examines the presence of young people in cyberspace, presenting it as an environment of both multidimensional risks and developmental opportunities. The study aims to analyse the functions that the Internet fulfils in the lives of the young generation, with reference to its instrumental, socialization, and entertainment roles, as well as to identify problematic phenomena resulting from excessive (problematic) use of interactive media. The paper draws on a review of the literature and the findings of recent empirical research. The findings indicate that the Internet has become a natural environment for youth socialization and identity formation, enabling the development of passions, the broadening of horizons, the establishment and maintenance of relationships, and access to knowledge. Moreover, the virtual world has been primarily designed and adapted to meet the needs of young people in their pursuit of personal, social, psychological, and even physical well-being. At the same time, growing concerns are raised about Internet addiction, escapism, neglect of responsibilities, emotional and relational disturbances, as well as exposure to violent content, misinformation, disorganization, risky behaviours, and even self-destructive tendencies. Health and psychosocial consequences such as depression, social phobia, sleep disorders, and weakened family bonds are also emphasized. The conclusions highlight the need for preventive and therapeutic measures (cognitive-behavioural, pharmacological, and family-based) and for education on the safe and responsible use of the Internet. While the Internet has become an indispensable element of young people’s everyday lives, its responsible use requires support from families, schools, and broader social institutions.Artykuł podejmuje problem obecności młodzieży w cyberprzestrzeni, ukazując ją jako obszar zarówno wielowymiarowych zagrożeń, jak i szans rozwojowych. Celem opracowania jest analiza funkcji, jakie pełni Internet w życiu młodego pokolenia, z uwzględnieniem aspektów instrumentalnych, socjalizacyjnych i rozrywkowych, a także identyfikacja zjawisk problematycznych wynikających z nadmiernego (problematycznego) korzystania z mediów interaktywnych. W opracowaniu wykorzystano przegląd literatury przedmiotu oraz wyniki najnowszych badań empirycznych. Ustalenia wskazują, iż Internet stał się naturalnym środowiskiem socjalizacji i budowania tożsamości młodzieży, umożliwiając rozwój pasji, poszerzanie horyzontów, nawiązywanie i utrzymywanie relacji oraz dostęp do wiedzy. Ponadto, świat wirtualny został wykreowany i zasadniczo dostosowany do potrzeb młodzieży w zakresie poszukiwania dróg, sposobów i źródeł osiągania przez nich dobrostanu osobistego, społecznego, psychicznego, jak również fizycznego. Jednocześnie obserwuje się narastanie problemów związanych z uzależnieniem od sieci (zagrożeń wynikających z problematycznego korzystania z Internetu), eskapizmem, zaniedbywaniem obowiązków, zaburzeniami emocjonalnymi i relacyjnymi oraz narażeniem na treści przemocowe, dezinformację, dezorganizację, dezintegrację, ryzykowne zachowania, a nawet tendencje autodestrukcyjne. Wskazano także na konsekwencje zdrowotne i psychospołeczne nadmiernego korzystania z Internetu, takie jak depresja, fobia społeczna, zaburzenia snu czy osłabienie więzi rodzinnych. Wnioski podkreślają konieczność podejmowania działań profilaktycznych i terapeutycznych (poznawczo-behawioralnych, farmakologicznych, rodzinnych), a także edukacji w zakresie świadomego i bezpiecznego korzystania z sieci. Internet jawi się jako niezbędny element codzienności młodzieży, jednak jego odpowiedzialne użytkowanie wymaga wsparcia ze strony rodziny, szkoły i instytucji społecznych
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
