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
Economic optimization of a brownfield redevelopment program at a regional scale
No full textLe redéveloppement des friches (RF) est une question qui préoccupe de plus en plus les urbanistes du monde entier. De plus en plus de friches, sites sur lesquels fleurissaient autrefois d'intenses activités économiques ou industrielles, sont désormais abandonnés ou sous-utilisés. Les friches industrielles sont souvent une source de nuisances pour les populations qui résident dans leur voisinage. En même temps, les friches industrielles situées dans les zones métropolitaines offrent de réelles opportunités de densification des villes. Le coût de déconstruction des bâtiments abandonnés, la gestion des déchets qui en sont issus et celle des polluants chimiques présents dans le sol et les eaux souterraines peut largement dépasser les bénéfices financiers escomptés sur lesquels les investisseurs privés fondent leurs décisions. L'existence de nombreux bénéfices économiques, sociaux et environnementaux, non pris en compte par les investisseurs privés, peuvent justifier un investissement public dans de tels projets, mais sont difficiles à évaluer en termes monétaires. Comme le montre la revue de littérature présentée au chapitre I, la plupart des analyses et des outils d'aide à la décision portant sur le RF sont réalisés au niveau des sites. L'objectif principal de cette recherche est de développer un modèle d'optimisation économique d'un programme de réaménagement d'un ensemble de friches à l'échelle régionale, et de vérifier sa pertinence comme outil d'aide à la décision auprès d'une grande collectivité. La mise en œuvre du modèle est illustrée de manière empirique dans la Vallée de la Chimie, qui est présentée au chapitre II, et comporte l'identification et la caractérisation de 30 friches industrielles et de 9 futures activités d'utilisation des sols. Le chapitre III présent l'évaluation des coûts de réhabilitation, où l'incertitude est traitée en utilisant une approche basée sur la connaissance subjective des experts. Quatre sources de coûts ont été identifiées : la décontamination des sols, la gestion des sols excavés, la déconstruction des bâtiments abandonnés, et le reconditionnement des sols. Le chapitre IV porte sur l'évaluation en termes monétaires des bénéfices privés, sociaux et environnementaux du RF. L'approche est basée sur le transfert de bénéfice pour estimer les multiples bénéfices d'un portefeuille de plusieurs sites et de plusieurs options de réaménagement. Le modèle, présenté dans le chapitre V, utilise l'analyse coût-bénéfices pour comparer différentes options de RF et pour identifier la combinaison optimale afin de maximiser le bénéfice net global sur une période de 20 ans. Le modèle tient également compte des interactions entre les projets et les sites, ce qui permet d'identifier un meilleur résultat qu'une approche site par site. Le chapitre VI présente d'abord une approche stochastique pour tester la sensibilité des résultats en ce qui concerne l'incertitude des données d'entrée, illustrée avec les intervalles des coûts de réhabilitation. Ensuite, le chapitre présente la mise en œuvre et la simulation de différents scénarios. Dans l'ensemble, cette recherche démontre de manière cohérente la pertinence des analyses économiques pour la prise de décision en matière de RF, et comment les facteurs d'incertitude peuvent être gérés pour porter les approches économiques à l'échelle régionale.Brownfield Redevelopment (BFR) is an issue of growing concern for urban planners all over the world. Brownfields are sites which once supported economic or industrial activities, but are now vacant, abandoned or underutilized. Their number is likely to increase, especially in former industrialized regions of Europe. Brownfields are often a source of nuisance for nearby residents, particularly in the case of contaminated sites (environmental and human health risks). At the same time, brownfields located within metropolitan areas offer genuine opportunities for urban development by reinvigorating distressed neighborhoods and avoiding costs linked to urban sprawl. The cost of removing derelict buildings and chemical pollutants in soil and groundwater may significantly exceed the expected financial benefits on which private investors base their decisions. Many indirect benefits (environmental, social, avoided public expenses), which could justify public investment in such projects, are hard to assess in monetary terms. As shown in the literature review presented in Chapter 1, most analyses and decision-support tools addressing BFR are carried at the site level. In view of assisting policy makers to design a portfolio of redevelopment projects that could maximize social welfare, the objective of this research is therefore to develop a model for the economic optimization of a BFR program at a regional scale. The implementation of the model is empirically illustrated in the Valley of Chemical Industry (Vallée de la Chimie in French), which is presented in Chapter 2, and includes the identification and characterization of 30 brownfield sites and 9 future land use activities. Chapter 3 presents the assessments of rehabilitation costs, where uncertainty is addressed using an approach built on the subjective knowledge of experts. Four sources of costs were identified: soil decontamination, management of excavated soil, deconstruction of derelict buildings, and soil reconditioning. Chapter 4 focuses on valuing in monetary terms the private, social and environmental benefits of BFR. The approach is based on benefit transfer to deal with the multiple benefits of a portfolio of several sites and several redevelopment options. Chapter 5 presents how the model, based on mathematical programming, uses cost-benefit analysis to compare different redevelopment options for brownfield sites, and to identify the optimal combination of BFR alternatives to maximize the overall net benefit over a 20-year period. The model also accounts for interactions between projects and sites, allowing to identify a better outcome than a site-by-site approach. Chapter 6 first presents a stochastic approach to test the sensibility of results in regard to the uncertainty of the input data illustrated with the intervals of rehabilitation costs. Then, the chapter presents the implementation and simulation of various scenarios. Overall, this research consistently demonstrates the relevance of economic analyses for BFR decision-making, and how can uncertainty factors be managed to carry economic approaches at the regional scale

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.
