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

Sea, agriculture and water quality: the case study of Vallevecchia (Caorle, Venice, Italy).
Full text linkRecently, several droughts have negatively affected agricultural activities on the Padana plain
(Italy), causing scarcity of irrigation water and both extended (up to tens of kilometres) and
prolonged saltwater intrusion. The wetland system of Vallevecchia (Caorle, Venice) is based on a
700 hectares-wide drainage basin reclaimed during the sixties on the sand littoral zone of the
North-Western Adriatic Sea.The system, by means of several hydraulic works allowing the inside recirculation of rainwater and
drain water, has multiple pioneering goals: limiting saltwater intrusion, enhancing irrigation water
availability during droughts, and reducing the diffuse pollution from agriculture (i.e. the nutrient
loads discharged into the eutrophic Adriatic Sea) through phytoremediation. We have intensely
monitored the water quality of Vallevecchia since 2003. Ever since, the system was sensibly altered
by the construction (ended in 2005) of two hydraulic infrastructures in order to increase its
efficiency: a check-gate to control the outflow from the system and a basin for water storage. The
traditional functioning scheme of the system was based on pumping the water collected by the
Sbregavalle channel into the Canadare channel, by the Vallevecchia pumping station. In order to
allow water recirculation inside the basin, the abovementioned deep structural modifications were
realized: the water storage basin, characterized by an internal volume of about 200000 m3, was
created by excavation works and construction of surrounding levees. A check-gate was built in the
Sbregavalle channel, to allow water retention inside the channel itself, limiting water expulsion
through the Vallevecchia pumping station. In this way, water can be retained into the channel and
be pumped inside the storage basin by a new pumping station which was appositely designed for
this purpose. This pumping station contains three submersible pumps, and is well integrated in the
local environment thanks to its limited size. The storage basin is linked to the Vallo channel, which
flows along the sea border of the Vallevecchia basin, by a pipe line in which gravity flow realizes.
A tank interposed between the pipe line and the Vallo channel allows flow regulation. Water can be
distributed in the area between the Sbregavalle and the Vallo channels through some regulating
gates which allow water flowing inside first order and second order channels.
The following parameters have been monitored: ammonia nitrogen N-NH4, oxidate nitrogen NNOX,
dissolved organic nitrogen D.O.N., particulate nitrogen P.N., total nitrogen T.N.,
orthophosphate phosphorus P-PO4, soluble unreactive phosphorus S.U.P., particulate phosphorus
P.P., total phosphorus T.P. and total suspended solids T.S.S. The choice of these chemical
parameters has been made because they are of maximum interest to control the pollution in
drainage basins and in lagoons of the northern Adriatic area. The long-term monitoring dataset,
including nutrient concentrations, water flows and environmental data, has consequently allowed
the evaluation of the system performances both under varying environmental conditions and
different system configurations.
Monitoring data analysis shows that the two new hydraulic infrastructures have led to a markedly
increased within-system abatement of nutrients from 2006 to 2009 as compared to the 2003-2005
period. Strikingly, the reduction of discharged nutrient loads has been achieved with only a
minimal management effort, e.g. each year the water storage basin was filled once. Consequently,
our results indicate that the check-gate plays a fundamental role in increasing the system efficiency,
and suggest that starting a simple, routine management (e.g. of the check-gate position and of water
recirculation, to achieve a better exploitation of the wetland) would make the system functioning
remarkably more efficient
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.
