    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The 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

    ANALYSIS OF THE EVOLUTION OF ANTHROPOGENIC COASTLINE ADVANCE BETWEEN MONFALCONE AND MUGGIA (NE ADRIATIC SEA) OVER THE LAST 200 YEARS IN A GIS ENVIRONMENT

    Coasts are land–ocean interfaces of high environmental and economic value. They are the most affected areas by urban settlements and economic and productive activities, and suffer from increasing anthropogenic pressure. About 10% of the world's population currently lives in coastal areas less than 10 m above sea level, and 40% within 100 km of the coast (UN indicators: http://www.un.org/esa/sustdev/natlinfo/indicators/methodology_sheets). The anthropization process has significantly modified and altered the natural and environmental characteristics of the coastal system, affecting the structure of natural ecosystems, the quality and quantity of natural resources and changing the landscape from natural to anthropic. In Italy, the morphology of the peninsula and its geographical position in the center of the Mediterranean make the coastal areas an extraordinary resource, both from an environmental, economic and cultural point of view. The Italian coastal area is highly anthropized, with 34% of the Italian population living permanently in coastal cities (ISTAT, 2022). The Italian coastline is about 8,300 km long, 13% of which is made up of artificial structures such as ports, hydraulic and coastal protection structures. In the last 20 years, 5 km of natural coastline has been lost every year due to the construction of new artificial structures (ISPRA, 2020). The study area is located in the Gulf of Trieste, a shallow semi-enclosed sea of about 500 km2 in the north-eastern Adriatic Sea, in the Italian region of Friuli Venezia Giulia (FVG). The FVG coastline are 111 km long, and the 55.4 % is highly anthropized (Fig. 1) (Zanchini et al, 2017). In the northern part of the gulf the coasts are characterised by beaches of fine or pebbly sand. In the eastern part, the coast is rocky, with narrow, pebbly and gravelly beaches (Brambati and Catani,1988), constituted by Eocene marls and sandstone of the Trieste formation and Cretaceous and Paleocene limestones. The coastal area near Trieste has been heavily modified by anthropogenic interventions that have altered both the natural coastline and the seabed. The southern part has rock coasts at the foot of abrasion escarpments, with several bays, such as those of Koper and Muggia. The aim of the study is to evaluate and quantify the evolution and the changes (advances) of the coastline and the consequent loss of the marine (littoral) environment and ecosystem between Monfalcone and Muggia, where the coastline is predominantly rocky, caused by anthropic activities over the last 200 years. To carry out the analysis, a series of historical charts of the study area from the last 200 years were collected. After georeferencing the charts, the past coastlines were digitized and compared with the current ones using the Geographic Information System (GIS). For example, Fig. 1 shows two of the past digitized coastlines, the one from 1922 and the one from 1927. The whole evolution of the coastline was analyzed, relating each change to the cause that produced it and the time period in which it occurred. The analysis highlighted that in some areas the advances caused by human activity were even hundreds of meters, mainly due to the construction of infrastructures, ports and industrial settlements. The only retreated section was in the Bay of Muggia (Fig. 1), where the changes were caused by the construction of a navigable canal. A good understanding of the rates of historical changes is a prerequisite for effective coastal zone management. Only by examining the risks and potential consequences it is possible to find high-quality and innovative solutions to protect the coasts and the social and economic activities based on them

    Variations on the Author

    “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 link
    We 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 link
    We 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

    We 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 text
    In 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.
