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
Multi-threat Sustainability Assessment of Bridges and Bridge Networks
No full textSustainable performance of critical infrastructure like bridges under both service loads and extreme events is of growing importance to the society. This performance of highway networks and their constituent bridges can be mapped to sustainability indicators like cost, embodied energy, carbon dioxide (CO2) emissions or resource utilization. With heightened load demands due to overweight trucks and natural hazards on the aging bridge infrastructure, an integrated multi-threat sustainability framework for bridges and bridge networks is essential. The existing sustainability
quanti cation methods and approaches lack a joint sustainability assessment considering bridge vulnerabilities to hazards as well as truck loads, especially using a probabilistic approach. The primary goal of this study is the development of probabilistic frameworks to assist and evaluate sustainability on two levels: bridge and bridge network.
Bridge sustainability is dependent on contributions from different life-cycle phases like construction, operation, maintenance, failure and demolition. Unlike past life-cycle studies, the probabilistic life-cycle sustainability analysis (LCS-A) framework proposed in this study considers life-cycle phase interactions as well as integrates
post-repair performance of bridge components while exploring the distribution of sustainability costs to provide a more holistic view of an bridges sustainability. Interactions
in the life-cycle emerge due to interventions such as maintenance activities which primarily benefit service load performance, but also enhance hazard performance, a previously unexplored secondary interaction effect from life-cycle studies. For bridges subjected to multiple hazard events in their lifetime, the impact of post-repair modification of bridge component behavior in LCS-A is significant and cannot be neglected. This study gathers the insights from bridge level LCS-A and integrates it into developing a probabilistic sustainability evaluation framework for highway networks
as well. The inclusion of bridge failures due to both spatial variation of hazard
as well as truck presence is a key advancement proposed through this research. The traffic simulation of overweight trucks on a bridge in the network is developed using the average daily truck traffic on the bridge and using extreme value theory to predict percentage of overweight trucks. The variation in hazard occurrence and intensity is captured by using a probabilistic suite of scenarios for the network. Advances are also made in the methodology to evaluate traffic emissions by incorporation of traffic flow modeling and fuel congestion into the network assessment.
The LCS-A and network frameworks developed in this study are capable of handling various sources of uncertainties, with propagation of uncertainties facilitated by use of surrogate models when predicting bridge failures. In addition to developing probabilistic distributions of sustainability metrics, this study also recommends using probabilistic sensitivity analysis to understand how the uncertainty in the sustainability
indicator is influenced by uncertainties in the input parameters. Such a
detailed sensitivity analysis highlights opportunities for reducing uncertainties in sustainability outcomes by focusing on reducing the uncertainties in the most important input parameters. The sustainability framework developed as part of this thesis also can be used to de-aggregate bridge or network sustainability into contributions from
their constituent components. A new sustainability informed component importance measure (SCIM) is proposed in this study that leverages the probabilistic nature of the sustainability contributions from individual components and maps it to system level sustainability consequences. The SCIMs proposed in this study is developed by
adopting a flexible system failure based on a user-defined threshold on the system level sustainability indicator. The temporal evolution of component importance due to aging related deterioration or potential change in user-de fined thresholds are also incorporated into the SCIMs. The probabilistic frameworks developed in this thesis can support owners in their efforts to improve bridge or network sustainability,such as evaluating the impact of interventions or repairs on performance of bridge for future hazards or service loads and making upgrade decisions to minimize impacts
of bridge failures to the surrounding natural and built environment. Moreover, stakeholders may pose sustainability objectives or intervention schedules for preferred risk threshold given new insight on the full probability distribution of sustainability outcomes
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

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.
