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
A Martial Meteorology: Carceral Ecology in the US South of Jesmyn Ward’s Sing, Unburied, Sing
No full textDuring a discussion of her novel, Sing, Unburied, Sing, Jesmyn Ward recalls her experience of Hurricane Katrina: “I sat on the porch, barefoot and shaking. The sky turned orange and the wind sounded like fighter jets” (Ward 262). The “weight of history in the South of slavery and Jim Crow makes it hard to bear up,” she continues. The future is full of worry, “about climate change and more devastating storms like Katrina and Harvey” (Block). In her depiction of the wind as fighter jets, Ward imbues the violent elements of the hurricane with a martial quality that demonstrates how weather and, in particular, storms, hold the capacity to unmake the world. Yet it is the history of the US South, of slavery and Jim Crow, that Ward uses to preface her concern about a turbulent future. In doing so, she foregrounds the racial dimensions of the Anthropocene by placing the carceral in conversation with the environment. Sing, Unburied, Sing also explores this much over-looked connection. By examining the novel’s twinning of racial and ecological violence, this essay traces what I call carceral ecology. Crafted from Ward’s imagining of a martial meteorology, carceral ecology transforms climatic phenomena like heat, rain, and storms into tools of western power. The novel thus unearths a southern history in which environmental design and manipulation have been used maintain a carceral state of control. In the end, Ward offers a counternarrative to a white Anthropocene, one that is attuned to the epoch’s entanglement with race
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

The “Universal Cannibalism” of Things: A Historical, Psychoanalytic Treatment of Melville’s Bartleby, Benito Cereno, The Encantadas, and Billy Budd
No full textEnglish Department Honors Thesis. Merrill Moore Co-winner 2012, Best Honors ThesisThis study will evaluate Herman Melville’s Bartleby the Scrivener, Benito Cereno, The Encantadas, and Billy Budd as evidence of Melville’s embrace of an historical view of the U.S. and will further analyze these novellas using a methodological framework that attempts to synthesize a historical lens and psychoanalytic perspectives. While the historical and psychoanalytical approaches may sometimes appear to resist reconciliation, they will generally complement each other. It is only through analysis that takes into account both the psychoanalytic and the historical that we can comprehend how intensive is Melville’s sense of a social degeneration that affected both the internal subjective demands on citizenship and the external evidence of history.College of Arts and ScienceEnglish Departmen
Clinical, behavioural and pharmacogenomic factors influencing the response to levothyroxine therapy in patients with diagnosed primary hypothyroidism
Get PDFBackground
Suboptimal thyroid hormone therapy including under-replacement and over-replacement is common amongst patients with hypothyroidism. This is a significant health concern as affected patients are at risk of adverse cardiovascular or metabolic consequences. Despite a growing body of evidence on the effects of various factors on thyroid hormone replacement, a systematic appraisal of the evidence is lacking. This review aims to appraise and quantify the extent to which clinical, behavioural and pharmacogenomic factors affect levothyroxine therapy in patients with primary hypothyroidism.
Methods/Design
The databases Web of Science, Cochrane Library, EMBASE, and PubMed will be searched. Patients must be adults over the age of 18 years, suffering from primary hypothyroidism including overt and subclinical hypothyroidism, and receiving levothyroxine treatment. Studies in children, pregnant women, and patients with secondary or tertiary hypothyroidism will not be included. We will also exclude studies focused on forms of thyroid hormone replacement therapy other than levothyroxine.
The primary outcome is to quantify the effect of clinical, behavioural and pharmacogenomic factors on thyroid stimulating hormone (TSH) levels. Secondary outcomes are the effect these factors have on Thyroxine (T4) and Triiodothyronine (T3) levels, mortality, morbidity, quality of life, treatment complications, adverse effects, physical and social functioning. Studies will be screened through reading the title, abstract, and then full text. Two reviewers will independently extract the data and select articles, and a third reviewer will be consulted if there is any disagreement. We will undertake a meta-analysis of studies in which there is a defined intervention or exposure, patients are receiving levothyroxine for hypothyroidism, there is an appropriate control group of levothyroxine treated patients that are not exposed to the intervention, and the primary outcome is determined by serum TSH levels. Studies will comprise of randomised controlled trials as well as observational data.
Eligible studies will be assessed for bias using the risk of bias tool available in the Cochrane Handbook 2011, and the quality of evidence will be judged according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. A flow diagram describing the data search will be created according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis: The PRISMA Statement. A narrative synthesis will be undertaken in the description of the data, and summary tables will be created of the results.
Discussion
This review will be the first systematic review of this nature. The evidence synthesised will be useful to general practitioners in their management of hypothyroidism. Findings will be disseminated at conferences and in professional and peer-reviewed journals
Black Queer and Trans Anthropocenes
No full textThis dissertation names a conceptual framework that reads black queer and trans aesthetics, politics, and modes of affiliation for their contributions to ecological inquiry and Anthropocene criticism. Through an analysis of Michelle Cliff’s diasporic novels, Marlon Riggs’s AIDS media, Tourmaline’s transgender avant-garde cinema, and Alexis Pauline Gumb’s experimental poetry, I track how specific aspects of planetary climate change develop out of the longue durée of slavery and coloniality; while at the same time, I examine new onto-epistemological ruptures that are brought on by the sheer scope and magnitude of our contemporary crises since the 1970s. These emergent ruptures call into question familiar understandings of agency, reproduction, and home—to name but a few of the topics explored herein—in ways that reframe these concepts as something at the very threshold of visual or discursive intelligibility in diminishing worlds on the precipice of death. I read such moments as attempts to make sense of ecological destruction and environmental transformation so as to protect life and articulate something for the future wellbeing of the planet and all of its inhabitants. Moreover, by bringing black ecological inquiry on the intersections between humanity, animality, and property to bear on queer ecofeminism, I show how these critical fields help us to assess a central paradox at the heart of Western environmental philosophy. That is, while Black people have historically been fabricated as nonhuman nature and renewable resources in the contexts of slavery, people deemed sexually deviant or gender non-conforming have historically been misconstrued as “unnatural” or “against nature.” Excavating this conceptual intersection in my primary texts and critical sources, I locate alternative ways of being and becoming human and find different methods for environmental stewardship or ecological interdependence that are not beholden to the logics of capitalist regulation, extraction, or disposability. As such, I argue that black queer and transgender histories, aesthetic practices, and lived experiences are essential to any accounts of social and environmental justice
