    Phantoms of Anglo-Confederate commerce : an historical and archaeological investigation of American civil war blockade running

    No full text
    During the American Civil War Wilmington, North Carolina and the Bermudian ports of St. Georges and Hamilton served as vital links in a complex trading network that developed to facilitate the exchange of southern agricultural products for war materials and civilian merchandise through a Union blockade of the Confederacy. Although that material contributed significantly to the Confederate war effort, Anglo-Confederate blockade running has received limited scholarly attention. Much of the associated literature is based on memoirs rather than scholarship and does not accurately, reflect that necessarily clandestine trade. The primary goal of this thesis is to produce a more comprehensive and detailed picture of blockade running, the cargoes carried through the Union blockade and the powerful steam vessels that made Anglo-Confederate commerce possible. Unlike previous treatments, this thesis combines the results of both archival and archaeological research. The results illustrate the evolution of strategies involved in both establishing and maintaining the blockade and those developed for running the blockade. Assessment of the vessel remains and historical data associated with the construction and procurement of steamers identifies the vessel types and confirms that blockade runners adapted extant technology. Contrary to the popularly held impression, no technological innovations were specifically developed to address the demands of the trade. The spatial distribution of wrecks and the minimal amount of cultural material surviving in association with them, provides strong evidence that cargoes were more valuable than the vessels. That premise influenced the strategy adopted by blockade runners. While Confederate salvors left little evidence of cargo, historical research revealed a wealth of new insight into the specific nature of that material. This new evidence provides a more accurate and detailed picture of Anglo- Confederate blockade running and the strategies, ships and cargoes that made blockade running between Wilmington and Bermuda a success

    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

    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
