    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

    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

    Connectivity, diversity, and demography of Lagenorhynchus dolphins of the North Atlantic

    The earth’s polar regions are facing an exceptional degree of environmental change in the Anthropocene, leading to an unprecedented rate of biodiversity loss. Cetaceans are important predators in these fragile ecosystems and are impacted by an array of multiple stressors, potentially impairing their fitness and long-term survival. Understanding to which extent cetacean populations are impacted requires comprehensive knowledge on their population dynamics. However, accessing elusive pelagic species, such as oceanic dolphins, proves to be a cost-intensive and high-risk endeavor. Consequently, large knowledge gaps remain in many species regarding their genetic connectivity, proportion of genetic variation, and demographic history. All of these aspects, however, are crucial for assessing the conservation status of present-day populations and help to make informed predictions on how future change may impact their survival. Due to dedicated monitoring of coastlines adjacent to the core habitat of understudied marine species over decades, opportunistic sampling of stranded cetaceans can provide a cost-effective opportunity to address these questions. Through international collaboration, samples collected by stranding networks in combination with other sampling approaches allow to obtain the samples needed to evaluate population dynamics of elusive species using state-of-the-art genomic approaches in an ecosystem-wide manner. The two extant species of the Lagenorhynchus genus of the North Atlantic Ocean, the Atlantic white-sided and the white-beaked dolphin, suffer from data deficiency due to their pelagic nature. A recent surge in interest from various stakeholders was driven by the prospective impact that climate change may have on these cold-water obligate species. Driven by recommendations to increase our understanding of Lagenorhynchus population dynamics and risk of impact from environmental stressors, this project aimed to gather tissue samples from stranding networks and other sources and implement high-throughput Next Generation Sequencing to address these components from a genetic perspective. As a result, this thesis provides novel insights into Lagenorhynchus biology and conservation, which are communicated through engagement with policymakers and the publication of scientific results. In the introduction of this thesis, I will lay out the early and recent advances in genetics and genomics to study natural populations globally and across species through time. With a focus on how genetic techniques have benefited cetacean conservation, I will then highlight the ongoing initiatives undertaken to understand and protect cetacean populations worldwide and in the North Atlantic specifically. The two target species and the importance of stranding archives and other sampling approaches for cetacean conservation are described to provide a context for the methodological approach of this thesis. Chapters 2 and 3 focus on each species separately, describing their genetic connectivity, diversity, relatedness, and gene flow informed by reduced representation sequencing. The results illustrate the stark contrast in population structure the two species display on a range-wide scale, reflecting their ecological differences and emphasising recommendations for conservation. Chapter 4 takes a comparative approach using whole-genome sequences to investigate patterns of genome-wide diversity and inbreeding, and to reconstruct the demographic histories of the species. The results put the previously assessed population structure in a wider evolutionary context, and allow for some predictions of future responses to global climate change aided by a species distribution modelling approach. In the final chapter of the thesis, all results are put into a context of conservation genomics on a broader scale and in cetacean populations specifically. The impact these results have on the conservation of North Atlantic Lagenorhynchus dolphins is being presented and putative impact is discussed. Finally, I will highlight pressing needs for future research to further understand Lagenorhynchus populations and assess their conservation status in light of increasing pressure through various anthropogenic stressors

    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.
