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

Den viktige elgen
Utmarkbeite er trolig den mest utbredte arealbruken i Norge, som i verden forøvrig. Etter at mengden beitende husdyr begynte å ned på midten av forrige århundre har ville hjortedyr tatt over deres plass i naturen. Disse ville populasjonene reguleres tett og forvaltes faktisk av landbruks- og matdepartementet. Så på mange måter kan man si at elgen er den nye kua. Hva betyr så elgen for oss? For naturen rundt oss? For samfunnet? Vi snakker om verdens største hjortedyr, en spisemaskin som kan omsette så mye som 40 kg plantemateriale om dagen. I Norge er det rekordmange elg om dagen – ofte 2 dyr per kvadratkilometer flere steder. Dette tilsier at elgen kan ha virkelig mye å si for skogen der den bor, og skal vi nå bærekraftsmålene til FN, og skal vi klare å reversere klimaendringene, ja da kan vi faktisk ikke la være å tenke på elgen.
Mitt doktorgradsarbeid har bekreftet at dagens beitetrykk fra elgen går hardt utover løvtrærne som den lever av. Men at det i hele studieområdet vårt ikke skulle finnes en eneste rogn som hadde unnsluppet elgens kjever, det var allikevel dystert nytt. I hvert fall for oss som ønsker å se løvtrær og artsmangfold i skogene. Jeg har også studert hvordan endringene forplanter seg i jordsmonnet og i undervegetasjonen. Ja elgen er viktig for hele økosystemet.
Men elgen er også en del av mangfoldet. Og den er jakt, den er kultur og den er tradisjon. Så hvordan veier vi opp alle disse positive og negative sidene ved elg? Avhandlingen min rundes av med oppstarten på noe nytt – ett nettbasert samarbeids og -læringsverktøy for å forstå elgens mange roller i naturen og i samfunnet. Gjennom tverrfaglig samarbeid og med tettere kontakt mellom forskere og samfunnet for øvrig, legger vi grunnlaget for å mer bærekraftig fremtid.Summary of thesis:
The important moose
Pastoralism and wild animal grazing on unfenced lands is probably the most extensive land use in Norway, as it is in the rest of the world. After the number of livestock grazers started to decline mid last century, wild species have grown to take their place. These wild ungulates are strictly regulated, under the jurisdiction of the Norwegian Ministry of Agriculture and Food. So, you could say that moose is the new cow.
We are talking about the world’s largest species of deer, an eating machine that can munch down as much as 40 kg of plant matter every day. In Norway there are record amounts of moose at the moment – often 2 animals per km2 in many places. This suggest that moose may really have a big effect on the forests where it lives and that if we are to reach the UN sustainability goals, and if we are to reverse climate change, then we cannot afford to ignore the moose any longer.
My doctoral work has confirmed that todays browsing pressure from moose is quite detrimental to the deciduous trees that it feeds on. But that we should not find a single rowan tree within our entire study area that had escaped the moose’s grinding jaws, that was rather sad news. At least for those of us that put a high value on deciduous trees and biodiversity in the forest. I have also studied how these changes subsequently influence the forest soils and understory vegetation. Yes, moose is important for the entire ecosystem.
But moose is also part of the diversity. Over 60000 Norwegians participate in the annual moose hunt, and associate moose first and foremost with social and cultural values. My thesis ends with something new – a web-based co-operation and learning tool for understanding the many roles that moose have in Norwegian nature as well as society. With interdisciplinarity and closer ties between scientists and society at large, we are laying the foundation for a more sustainable and equitable tomorrow
