Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Living with an unsustainable food system: can food democracy resolve the dilemmas?
No full text Tim Lang proposes that a set of \u27New Fundamentals\u27 are now clear yet policy-makers have so far failed to get sufficient intellectual, political and economic grip on the seriousness of the situation. For a moment, in 2006-08, this looked possible. Rising oil and food commodity prices shocked even Western policy-makers. They were used to food prices troubling developing but not developed countries. When prices dropped, sighs of relief were heard, but troubles have re-emerged in the 2010s. Are the tectonic plates merely moving only to resettle in a new place, or is food economic volatility now the status quo, adding to the world\u27s financial instability? In this lecture, Tim Lang will take a long view. He will suggest that the 20th century\u27s apparent progress in resolving the Malthusian question (about land, food and population) has been done at considerable cost. Oil underpinned the 20th century drive for productivity. As it went through technical and managerial revolutions, the food system\u27s impact on the environmental was increasingly well documented. The impact on soil, water, climate, land use, and biodiversity are now all serious. The social implications, too, are sobering. Food culture is distorted. Social inequalities in consumption are both global and intra-national. Health indices show both hunger and obesity; and diet-related disease delivers huge healthcare costs. Surely the prevention of such problems ought to be driving policy yet it does not. Surely, we ought to be debating resource allocation, price-setting, and what is meant by efficiency, yet business-as-usual reigns. Or does it? The lecture will present some signs that the enormity of the challenge is troubling policy-makers\u27 normality. The lecture will suggest that governments, food companies, and civil society (ie all of us) need to engage with this debate. It should not be left to vested interests alone. Thus, the 21st century looks set to resuscitate an old strand in food policy: the pursuit of food democracy, how to ensure that all people are fed equitably, healthily and with dignity in a manner that enables others to do so too. This is a socio-political not a purely technical or managerial or scientific problem. In that respect, the lecture,. Currently, much attention is on technical innovation – not just GM but an array of novel solutions to food on and off the land. Less attention is being given to social issues where the possibilities include: restructuring food markets, rapid consumer behaviour change, re-shaping cultural tastes, altering price signals. These require the state and citizens to act differently: less \u27leave it to markets\u27 and more \u27re-frame markets\u27. Less \u27let consumers choose\u27, more open support for \u27consumers are choice-edited anyway\u27. The dominant policy language is, at best, replete with \u27nudge\u27 thinking, the fashion for behavioural economics. The lecture will propose the need for open and democratic debate about food futures. It will propose that the food security debates are no more and no less than a key test for whether our food system is shaped by food control or food democracy. It will warn against technical triumphalism and urge a more balanced integration of societal and supply chain change.

Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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.
