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
Synthesis and Self-Organization of Charged Nanocrystals
Full text linkDepartment of Materials Science and EngineeringColloidal nanocrystals (NCs) have attracted tremendous attention because of their unique size-, shape- and composition-dependent properties which offer great potential for their use in wide application fields like electronic, optoelectronic, and energy fields. In particular, the self-organization of these functional building blocks into suprastructures can realize unique multifunctional or collective physicochemical properties that are not observed in individual NCs. Among various strategies to organize NCs, the introduction of charged surfaces to NCs grants an anisotropic driving force like electrostatic interaction, which offers an additional degree to form novel self-assembled structures. Accordingly, there have been significant research efforts to chemically develop the charged NCs by introducing of ionic polymers or long-chain ionic molecules on the NC surfaces. However, these sterically bulky organics generally result in additional collective molecular interactions, atomic dispersion forces, and entropic contributions to affect the organization of NCs. Recently, an alternative surface modification methodology was developed to replace the organic ligands with inorganic anions on the surface of NCs and enabled the synthesis of all-inorganic charged NCs with desired surface charges. The introduction of the ???inorganic ligand??? can rule out the additional intermolecular interactions between surface organics and accordingly provides the ideal model system for understanding the correlation between the building block and the self-organization behavior of the charged nanocrystals.
In this dissertation, the chemical synthesis of charged NCs and their self-organization based on the induced interparticle interactions are described. In the first part, I investigated the self-organization and the colloidal behavior of the oppositely charged all-inorganic NCs based on the electrostatic interactions. All-inorganic charged NCs were selectively synthesized with molecular inorganic ligands or by the treatment with a stripping agent, which introduced the negative or positive charges onto the NC surface, respectively, to rule out the additional interaction from organic species. Three suprastructure phases, including patchy, patchy bridged, and fully coated particles were obtained depending on the charge states of suprastructures. I focused on the correlation between the colloidal behavior of suprastructures, and the size, content ratio, and concentration of oppositely charged NCs, and the phase diagram was constructed according to the NC concentrations. Especially, I observed the behavior of NCs as surface stabilizers exhibiting unexpected colloidal stability in the fully coated phasesthus, I proposed the concept of ???nano-ligands???. This concept was applicable to a wide range of material combinations and enabled the chemical designing of the self-organized suprastructures.
The second part of the dissertation describes the synthesis of matchstick-shaped Janus nano-surfactants and the programmability of the self-assembly with controlled surface amphiphilicity. Molecular amphiphiles are known as promising building blocks for organizing ordered structures through specific and local interactions. Inorganic Janus NCs can impart functionalities in addition to the structural ordering, however, the geometry of Janus NCs was limited to the sphere or dumbbell shape. I synthesized the matchstick-shaped Janus nano-surfactants which mimic the structure of the organic molecular surfactant. The amphiphilic structure was introduced by the selective ligand exchange process based on the hard-soft acid-base theory. Diverse ordered structures such as lamellar, curved, wrinkled, cylindrical, and micellar structures were exhibited depending on the controlled surface amphiphilicity. I aimed to study the correlation between the phase selectivity of suprastructures and the properties of matchstick-shaped nano-surfactants.ope

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.
