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
Potential of organic rankine cycle based heat recovery systems for power generation
No full textDue to intense fuel dependency on energy production in the world, cost of energy has a
greater bearing on the prices of fossil fuels. Most of the countries in the world are
suffering due to this and Sri Lanka is no exception. It is in this context promotion of
optimize the usage of thermal power generation, is so vital to the country. Even though
fossil fuel base power generation plays a greater role as a source of primary energy in
the country, major portion wasted to environment. WHR systems have been already
introduced, but most of them are not performing effectively and efficiently. On other
hand, novel systems and technologies required to investigate, to recovery most of the
wasted heat of thermal plant while increasing the system efficiency and reducing the
fuel cost. Conceptual thermodynamic cycles such as Trilateral Flash cycle, Organic
Rankine cycle, Kalian cycle and Gaswami cycle, can be successfully incorporate for
WHR applications. Hence, purpose of this research was to assess the amount of waste
heat generated by thermal plants in the country while discussing the possible
technologies that can be introduce for heat recovery. Further, discuss about selection of
most suitable option and carryout thermo-economic analysis as a case study.
Fluid selection and system optimisation based on heat source temperature are two most
critical aspect of Organic Rankine Cycle. Eleven fluids were investigated to optimize
the work output by varying the evaporator temperature and varying the expander
pressure ratio with theoretical model. In evaporator analysis, Heptane, Pentane and
Decane shows favourable results in terms of work outputs while, in terms of efficiency,
Decane and Heptane are better. Further it is recommended to use fluid Pentane, when
source temperatures of WHR lies between 45 – 190 oC, while fluid Heptane is
recommended when source temperature between 190 – 260 oC. Fluid Decane is
recommended when temperature between 260 – 340 oC. Respective monographs were
developed where one point on the graph can denote approximate work output,
efficiency, pressure, temperature, etc. Based on expander analysis, Decane, Heptane
and Toluene fluids have shown higher work outputs while, in terms of efficiency,
Decane is better. In expander selection, when inlet/outlet pressure ratios are less than
10, fluid Decane is recommended. Further, when ratios are in between 10 – 13 and 13
– 20, fluid Heptane and fluid Toluene are recommended respectively. Refer to these 03
fluids, monographs were developed accordingly.
Refer to optimum working regions of temperature analysis; fluids were selected for
economic evaluation. Waste heat recovery opportunities were selected from existing
thermal plants for the case study and electric outputs were obtained for each plant,
based upon selected fluids from theoretical model. Then maximum work out of each
opportunity was selected for further economic evaluation under 07 different scenarios.
Possible future economic situations of the country were predicted under those
scenarios and carryout NPV calculations for each, to evaluate the investment feasibility.
Scenario 2, 3 and 7 are the most possible situations of the country in future and for
those conditions, WH opportunities at Supugaskanda, Lakvijaya, Keravalapitiya and
Kelanithissa are most feasible to recover waste heat with ORC system

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.
