Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Peptoids : targeting sequence specific high molecular weight materials for protein mimetic applications
No full textThis thesis is restricted to Strathclyde users only until 30th November 2028.Synthetic biomaterials currently do not possess the molecular accuracy and dynamic biochemical activities found in natural biopolymers, such as proteins. For over fifty years, scientists have been working to bridge this gap by creating synthetic materials that mirror the intricate complexity and functionality of proteins. However, the challenge of devising improved design strategies and synthetic methods to create materials that encapsulate the full spectrum of folded, protein-like architecture using entirely non-natural building blocks remains. Poly N-substituted Glycine ‘Peptoids’ are an interesting class of peptide mimetics which have been demonstrating their ability as potential candidates which fulfil the objective of biomimicry. They provide bioinspired, yet non-natural, affordable, and stable chemical structures that overcome many issues associated with peptides. Their N-substituted Glycine backbones provide protease resistance while effectively mimicking the spacing between the essential chemical functions of bioactive peptides. Peptoids have been gaining significant attention due to their modular synthesis which allows precision sequence control and have recently been shown to possess simplified intermolecular interactions and unique self-assembled nanostructures that resemble proteins. In this thesis I present the study of two different peptoid systems which were used to develop functional high molecular weight materials to target protein mimicry. Our first approach focused on the use of surface functionalised peptoid nanosheets (PNS). These materials represent an interesting class of self-assembling nanostructures which have a thickness of about three nanometres and a length of up to 100 micrometres. As a result, they possess a large surface area which can be used as a structural scaffold. Through sidechain modification of PNS forming sequences, PNS with a variable density of surface accessible azide functional groups were prepared. Subsequent copper-catalysed azide–alkyne cycloadditions (CuAAC) allowed the attachment of complex species such as fluorophores, gold nanoparticles and cyclic (RGD) ligands to prepare functional PNS which were used in applications ranging from Cryo-electron microscopy to cell culture experiments with mesenchymal stem cells. In addition to PNS studies a novel synthetic approach which targets sequence specific high molecular weight poly-peptoids, using N-substituted glycine N-thiocarboxyanhydride (NNTAs) in combination with conventional solid phase peptoid synthesis (SPPS) was investigated. This is the first time ‘designed’ peptoid-block-polypeptoid species have been synthesised in this way, at the time of preparation. This method was developed in response to the requirements of attaining high molecular weight sequence specific peptide mimetics which could encompass the structure of natural proteins and peptides. Over the course of these studies, di-, tri- and branched co-polypeptoid possess low dispersity (Ð) were demonstrated. Subsequent polymerisation improvements are also provided which highlight solvent selection, resin consideration and how nitrogen bubbling impacts polymerisation. The combination of the aforementioned consideration culminates in the preparation of a A-B-A type tri-block antimicrobial species.Synthetic biomaterials currently do not possess the molecular accuracy and dynamic biochemical activities found in natural biopolymers, such as proteins.

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.
