    The European wildcat (Felis silvestris) is an elusive felid legally protected in Europe under the Appendix II of CITES, yet ecological knowledge for the Italian populations remains scant. Exceptions are a few studies that estimated population density in Southern Italy and the Alps. Here we estimated the population density of wild-living cats, i.e. wildcats, domestic cat (Felis catus) and their putative hybrids (Felis silvestris x catus; hereafter ‘hybrid’), while also investigating their occurrence and activity patterns in the Foreste Casentinesi National Park (Tuscany-Emilia Romagna), Italy. By using a camera-trapping grid with 59 cameras spread over 355.87 km2 from 31 August to 18 November 2020, we collected 180 wild-living cat detections, which we classified based on coat pattern as 65 wildcat, 23 domestic cats and 32 hybrid detections at 25, 4 and 10 stations respectively; we individually identified 15, 3 and 9 wildcats, domestic cats and hybrids, respectively. The most supported multi-session SECR model estimated the population density of wildcats, domestic cats and hybrids to be 3.09 (95% CI = 1.85 — 5.17), 0.61 (0.19 — 1.92) and 1.85 (0.96 — 3.59) individuals/100 km2, respectively. Basal detection rates g0 were affected by camera placement(road vs. trail), with higher values for the trails irrespective of the type of cats. The most supported multi-species occupancy model estimated the occupancy of cats to be 0.66 (95% CI = 0.40 — 0.84), 0.07 (0.02 — 0.28) and 0.29 (0.12 — 0.55) (95% CI = 0.40 — 0.84; 0.02 — 0.28; 0.12 — 0.55) for wildcats, domestic cats and hybrids, respectively. Distance to municipalities negatively affected not only domestic cats’ occupancy, but also the detection probability of all cat types whereas cameras located on trails resulted in lower detection probabilities for wildcat, but higher for domestic cats. The activity level of cats was relatively low, being estimated at 0.33, 0.48 and 0.35 (95% CI = 0.22 — 0.40: 0.24 — 0.59; 0.23 — 0.43) for wildcats, domestic cats and hybrids, respectively. Diel activity largely overlapped between cat types with an average estimate of 0.76. and nocturnal activity was the most supported diel niche model using the Maximizing Hypothesis set, irrespective of cat type. Although our camera array was not established specifically to monitor wildcats, it provided a novel baseline of ecological estimates for the wild-living cats within this protected area. Our results stress the importance of limiting the number of domestic cats that roam freely within this protected area of wildcat range

    Going Beyond Counting First Authors in Author Co-citation Analysis

    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

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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.
