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
Essays on the provision and regulation of healthcare services
Get PDFChanges in healthcare regulation can have unintended consequences on the provision of healthcare services and health outcomes of individuals. This dissertation quantifies the indirect effects of changes in healthcare regulation in three different settings. In the first chapter, I examine the effects of an increase in Medicare fees on nursing homes' willingness to treat Medicaid beneficiaries. Both Medicare and Medicaid offer health insurance, but they cover different services and pay healthcare providers at varying levels of fees. The divergence between the payment structures of the programs can create conflicting incentives for nursing homes, as Medicaid fees are less generous than Medicare fees. In the case of nursing homes, Medicare pays for skilled nursing care and up to 100 days of residency, while Medicaid pays for custodial care and until the resident dies or her condition improves. Thus, admitting a Medicaid resident has dynamic implications for future capacity constraints on nursing homes, as assigning a bed to a Medicaid resident will prevent the facility from using the bed for future highly profitable, Medicare residents. I find that capacity-constrained nursing homes respond to an overly generous Medicare fee by substituting away from Medicaid patients, who are low-profit patients. I exploit variation in the number of certificate-of-need and moratorium laws across states to approximate for the severity of capacity constraints. The chapter provides empirical evidence pertaining to indirect effects of Medicare policy on the healthcare utilization of non-Medicare beneficiaries and enriches the ongoing debate over the conflicting incentives between the Medicare and Medicaid programs and how this disconnection affects beneficiaries.
In the second chapter I study the impact of Prescription Drug Monitoring Programs (PDMPs) on suicides. PDMPs aim to discourage prescription drug abuse and diversion by requiring pharmacies to report the names of both patients and prescribers to a central database when dispensing controlled-substance drugs such as OxyContin. The recent empirical evidence supports the critical role PDMPs play in reducing opioid prescriptions, especially those with the highest potential for abuse. In this study, we hypothesize that a negative supply shock to the market for diverted drugs, like the implementation of a PDMP, has differential effects on the total number of suicides. We first develop a dynamic model of addicts' choice between continued drug use, exerting effort to quit drugs, or committing suicide. In the absence of drug treatment services, a negative shock to the supply of prescription drugs makes a drug habit unsustainable, and thus the addict commits suicide. On the other hand, in places with strong addiction-help networks, the productivity of a unit of effort towards recovery is higher. In this case a negative supply shock boosts the incentive to seek treatment. We test the predictions of our model using information regarding the number of suicides and treatment facilities at the county level and find that PDMPs reduce suicides in counties with strong addiction-help networks. A major policy implication of this study is that access to drug treatment centers is an important factor in the fight against the opioid epidemic.
Finally, in the third chapter I explore the responses of pediatricians to the implementation of the Children's Health Insurance Program (CHIP) in 1997. The findings reinforce prior evidence that pediatricians decrease their work hours in response to increases in the number of Medicaid- enrolled children. This is consistent with CHIP crowding out private insurance for children. I provide evidence that the response is due in part to changes in the extensive margin, as physicians in high-expansion states are more likely to move from solo practices to large practices such as group practices and hospitals. The latter results suggest that expansions in public health insurance can change the labor supply of physicians as well as the market structure of healthcare markets.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-05-01The student, Adriana Corredor Waldron, accepted the attached license on 2019-04-12 at 09:31.The student, Adriana Corredor Waldron, submitted this Dissertation for approval on 2019-04-12 at 09:44.This Dissertation was approved for publication on 2019-04-12 at 13:53.DSpace SAF Submission Ingestion Package generated from Vireo submission #13578 on 2019-08-22 at 16:21:03Made available in DSpace on 2019-08-23T20:44:43Z (GMT).

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.
