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

Essays in Health and Labor Economics
Get PDFIn the United States, health insurance is often necessary for access to regular, affordable health care. With only eight of every hundred Americans buying private insurance plans on the individual market, the main sources for health insurance traditionally have been employers and the government. As new laws are being debated and introduced to reform an expensive health care industry in which nearly one-sixth of the population is uninsured, research is needed in order to evaluate the costs and benefits of these policy changes and to predict their success. To this end, in addition to understanding how likely individuals are to adopt new health insurance policies, we also should be interested in knowing how the demand for health insurance and changes in its accessibility will affect non-medical decisions. Specifically, labor market choices have been theorized to be directly related to decisions involving insurance coverage. If the availability of health insurance distorts a workers' job-related decisions, then the changing the landscape for how to access insurance may reverberate in employment outcomes. My dissertation focuses on understanding the factors that influence the demand for health insurance and the role that health insurance plays in an individual's decision to work, where to work, and how much to work. Specifically, I focus on the following three related questions: how does the demand for insurance affect labor market decisions such as when to exit unemployment? what drives insurance demand, and in particular, what motivators work best to increase demand for health coverage among the uninsured? and lastly, what are the supply-side employment responses to the provision of free or reduced-cost public health insurance? My first chapter explores how the demand for health insurance can change re-employment decisions among the unemployed, as well as the speed at which individuals return to work. Past research on this issue focuses on job-to-job switches and "job lock" but has yet to focus on individuals looking for work. This chapter uses data on laid-off individuals from the Medical Expenditure Panel Survey to compare the job search behavior and outcomes of individuals who differ in their demand for health insurance. I use three proxies for demand, based on spousal health and past insurance offer take-up decisions. Although each is potentially confounded by unobserved determinants of job search, I use a difference-in-differences and propensity score designs to isolate plausibly causal effects. I find consistent patterns across all three proxies (despite different potential omitted variables biases). Overall unemployment durations do not vary with demand for insurance, but this masks variation in the types of jobs taken. Individuals with higher demand for insurance have higher hazards for exiting unemployment into a job with insurance, but lower hazards for exiting to a job without insurance. This points to effects of insurance demand on both search effort and reservation wages, and to potentially important distorting effects of employer-linked health insurance. Whereas the first chapter takes variation in demand for insurance as a given, my second chapter digs deeper into the basis for this variation and whether it can be affected. In this chapter, I investigate the reasons the uninsured choose to forego insurance coverage and the impact of different messages on their insurance demand. Working with Enroll America, a large non-profit dedicated to decreasing the number of uninsured Americans, I conducted a stratified experiment to determine the best communication strategies to encourage participation in the healthcare exchanges. We test a combination of the following behavioral and information treatments: a risk treatment that emphasizes the average financial risk for someone without health insurance; a norms treatment that alerts our participants that staying uninsured will be against the law; a savings treatment that highlights the average savings available at the exchanges; a wording treatment where we refer to the Affordable Care Act (ACA) as "Obamacare"; and lastly, a cost-calculator treatment that allows individuals to explore the likely cost of insurance based on their own characteristics. Among the uninsured, we find that the cost-calculator treatment, the risk treatment, and the mandate are most effective in increasing intention to purchase insurance. The cost-calculator and the risk treatment increase informedness among this population, but the cost-calculator (when paired with the savings treatment) is the only treatment that increases willingness to pay for insurance. We use the information on willingness to pay to construct sub-group price elasticities of demand to compare to previous work interested in the demand for health insurance. Overall, the results of this chapter highlight the importance of informational campaigns to increase awareness of the costs and benefits of health coverage, particularly after large changes such as those implemented by the ACA.My third chapter continues by looking at the changes that have been introduced as a result of the ACA. Specifically, it explores whether expanding access to government-provided insurance affects individuals' decisions regarding employment and overall hours of work. Recent findings have suggested that increasing access to health insurance outside of employment has a sizable, negative impact on labor force participation. Along these lines, the Congressional Budget Office predicted that the expansion of Medicaid and private health insurance will cause a 1.5 to 2% reduction in hours worked in the first ten years. Comparing states by whether they chose to expand Medicaid under reforms introduced by the ACA, I look at changes in the probability a childless adult receives Medicaid, as well as changes in this group's employment likelihood and hours of work. Using household survey data from the CPS monthly survey and ASEC Supplement, I confirm a marked increase in the percent of childless adults insured by Medicaid but find no statistically significant changes in employment outcomes. I compare these results to other estimates of "employment lock" in recent literature. These results, though imprecise, align with the findings in Chapter 1 which suggest that overall employment is not drastically affected by insurance demand

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.
