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 importance of plants and fruits for the diet and conservation of forest birds in Mongolia
Get PDFThe Khangai and Khentii mountainous regions, along with the Selenge River basin in Mongolia, mark the southern border of the Siberian Great Taiga. These areas are known for their biological diversity and the variety of native animals they support. The diversity of forest birds is closely linked to the unique environment and food chain found within forest and taiga ecosystems. Understanding the relationship between forest birds and their ecosystem is crucial for environmental protection and the sustainable development of forests and woodlands. Forest birds feed on resources such as small vertebrates, invertebrates, berries, and seeds, which contributes to an increase in bird species that rely on these food sources. They play a vital role in maintaining the balance of the forest ecosystem and helping to create a diverse biological community. Birds that inhabit the forest are crucial to this ecosystem, as they provide habitat for other animals. Forest-dwelling animals constitute an essential habitat unit and spend most of their life cycles there, fostering many positive relationships, such as using tree trunks for storage and food reserves. The forest and its biodiversity not only create a cohesive system but also highlight the importance of understanding and further researching the habitats of two species of resident forest birds that primarily feed on berries found in the environment. Additionally, the study identified a common range of 11 species of berries and non-timber products, as determined in detail through core and habitat area analysis using MaxEnt modeling. With this study, the habitats of both birds and non-timber products were classified according to the 12 Forest Vegetation Zones of Mongolia, clarifying the relationship between the species. Preliminary results from the habitat overlap analysis and similarity analysis of forest birds, berry hotspots, and the habitats of the 11 common berry and bird species indicate a need for more detailed research. This is essential to clarify ecosystem services, assess the effects of climate change, and plan sustainable development concepts within this sector, as well as basic conservation recommendations for forest protection. Studying the diversity, life types, feeding behaviors, and relationships of birds that play a crucial role in the forest ecosystem is essential for supporting sustainable development in our country. This is particularly important given our nation’s unique forest resources and its vulnerability to conservation issues. In particular, it is necessary to investigate the relationship between birds and the balance of the forest-taiga ecosystem, which serves as a significant source of surface water and forest reserves. There is a lack of interdisciplinary participation in this research, which is vital for understanding the distribution of berries and plants that support various bird species in their habitats.

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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
