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
The agricultural financing gap in Zimbabwe: rationing, sustainable credit access and participation in rural financial markets
No full textThe study is an examination of agricultural finance for smallholder communal farmers in Zimbabwe. It is accepted as reality that generally in Africa and particularly in Zimbabwe there exists a gap between the supply of and demand for credit among communal rural farmers. There have been previous attempts by governments to close the finance gap through supply of cheap credit but these efforts have neither been successful nor sustainable. The gap has been sustained by arguments that financing rural agriculture has high transaction costs, low returns on investment and is risky business. Formal financial services providers prefer to provide loans to well established urban businesses, rather than numerous small loans to scattered rural farmers in remote areas where transport, communication, energy and farm infrastructure are underdeveloped. The result is a serious and long lasting rural finance gap that keeps the economic potential of agriculture underused. Banks require collateral security from farmers but this is a major constraint due to land tenure restrictions. There have been some studies around the subject of rural financing and rural financial markets. A review of literature reveals that not much has been invested in studying the determinants of access to rural financing and of credit rationing for smallholder farmers by formal financial institutions in Zimbabwe. The empirical methods used in this study have not been employed in Zimbabwe to identify and recommend policy options to close the finance gap. The specific objectives were to i) to identify and examine the determinants of access to agricultural financial markets for smallholder farmers in Zimbabwe, and ii) to assess credit rationing as a result of the demand for loans exceeding the supply, by identifying and examining the determinants of credit rationing among smallholder farmers in Zimbabwe. Objective (iii) would draw from objectives (i) and (ii) to recommend policy options and financing models to close the rural agricultural finance gap for sustainable and smallholder inclusive rural financing for agricultural value chains in Zimbabwe. Cross sectional data was collected from a random samples of smallholder farmers residing in purposively selected wards and used for empirical analysis. The analysis used the double huddle model to determine the determinants of access and intensity of participation of farmers in rural financial markets. The seeming Unrelated Regression (SUR) model was used to analyse the determinants of credit rationing. Credit rationing was sub classified into quantity rationed, risk rationed and price rationed farmers. The analysis of credit rationing in three different categories using the SUR model shows the effects of the explanatory variables in a more critical manner that provides a better understanding of the determinants of credit rationing among small-scale farmers. Smallholder farmers’ perception of risk affects access to agricultural financial markets. Rain-fed agriculture has a high risk of crop and livestock failure due to variability and unpredictability in weather patterns and climate change related extreme weather events including droughts and floods. The results also showed that farmers in remote areas that are distant from the formal financial markets have less access to credit facilities. Communal smallholder farmers in Zimbabwe face significant levels of credit rationing in various forms. Credit demand is in excess of supply at various interest rates. Credit availability is a more critical issue in Zimbabwe than interest rates. Key policy interventions that can improve access to agricultural financial markets include improving extension contact in order to improve crop and livestock productivity, which in turn will improve farmers’ profitability and ability to repay farm credit. Infrastructure development including the development of rural growth points in remote areas can attract financial service providers to decentralise and reduce the distance to the financial services markets, transaction costs and interest rates. There is need for the Government of Zimbabwe (GoZ), to formulate and implement a Rural Finance Policy and Strategy to address the access and credit rationing challenges. The policy should facilitate development of financial sector infrastructure that enables broadening outreach in remote areas through establishment of effective payment systems, credit reference bureaus, warehouse receipts, collateral management and weather indexed insurance. Linkages between community based Member Owned Financial Institutions (MOIs) and formal financial services providers will contribute to addressing the rural finance gap.University of the Free State, School of Post Graduate Studie

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.
