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
Ecological impact of fire place use in urban forests and consequences for visitor management
Get PDFUrban forests are popular recreation areas in Europe. At the same time, these
forests are important habitats for plants and animals and often harbour a high
biodiversity. Recreational activities, for example picnicking and grilling and in
particular the creation and usage of fire rings outside official picnic sites ("wild" fire
rings), can cause extensive damage to soil and vegetation. Firewood collection
depletes woody debris, leading to a loss of habitat for specialized organisms.
Economical consequences of forest recreation include maintenance costs of
recreational infrastructure and diminishing revenues due to visitor-related damage
to trees and subsequent reduction in timber quality.
In the present thesis I examined the effects of fire place use on the forest
soil, including soil microbial biomass and enzyme activity, ground vegetation,
shrubs, trees and amount of woody debris. In addition, the reduction in timber
value resulting from recreational damage to trees was estimated. In order to
develop and implement measures, it is important to find out why forest visitors
create and use "wild" fire rings instead of official picnic sites. Therefore, I
conducted a forest visitor survey focusing on visitor preferences concerning fire
places. An experiment was conducted with four new fire places designed to fulfil
forest visitors' requirements, and a follow-up survey documented visitors'
reactions. A survey aimed at forestry experts in the whole of Switzerland provided
valuable information on foresters' perceptions concerning the consequences of
picnicking and grilling and forest recreation in general.
At frequently used fire places we found reduced plant species densities in
the ground vegetation and shrub layer and changes in plant species composition.
Picnicking and grilling also reduced the height and changed the age structure of
shrubs and young trees. The amount of woody debris was lower in disturbed plots
than in control plots.
Soil microbial biomass (Cmic and Nmic) and dehydrogenase activity were
differently affected by short- and long-term trampling. In a short-term experiment,
these soil characteristics decreased at low and medium, but not at high trampling
frequencies. In contrast, the same soil characteristics decreased with increasing
trampling intensity in a long-term field survey at fire places that had been in use for
more than a decade. The activity of β-glucosidase was only affected by short-term
trampling. Phosphomonoesterase activity was most severely affected by long-term
trampling, most probably as a result of the loss of plants.
The reduction in timber value due to visitor-related damage to trees ranged
from 19 to 53 € per hectare and year in two suburban forests. Total recreationinduced
costs, i.e. additional expenses and reductions in timber value exceeded
10% of the total annual expenditures of the two forest enterprises examined.
The forest visitor survey revealed a preference for fire places near streams,
away from forest roads and close to open spaces. While some visitors highly
appreciated the well-equipped official sites, others preferred more natural
infrastructure with pieces of stones forming a fire ring rather than concrete rims,
and logs to sit on instead of benches. Experimental fire places consisting of a ring
of stones and logs fulfilled the needs concerning infrastructure of visitors who
normally use "wild" sites. However, the location of fire places was termed more
important than their infrastructure. Forestry experts' perceptions regarding reasons
for "wild" site creation differed largely from the results of the forest visitor survey.
According to experts, an insufficient number of barbecue pits, available firewood
and forest visitors seeking adventure and romanticism repeatedly lead to the
creation of "wild" fire rings
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.
