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
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
Aerosol-fog interactions in the Italian Po Valley
No full textAtmospheric aerosol particles, tiny solid or liquid particles suspended in air, play a crucial role in environmental processes by interacting with both radiation and clouds, including fog. These interactions contribute to a range of environmental and health-related issues, both on their own and through complex interactions. One of the most polluted regions in Europe is the Italian Po Valley, frequently covered in fog. With a more than 30-year long history in aerosol-fog measurements, the research station San Pietro Capofiume (SPC), located in a rural area near Bologna, is an ideal site for studying aerosol-fog interactions in a changing atmosphere. Despite the fact that aerosol-fog interactions have been extensively studied worldwide, especially in recent years, many uncertainties and challenges persist. This thesis aims to investigate aerosol-fog interactions in the Po Valley, contributing to a deeper understanding of fog processes such as formation and dissipation, as well as shifts in fog occurrence in the context of a warming climate and cleaner air. These insights are relevant for various fields such as air quality or the transportation sector, but are e.g. also needed to validate fog model results and remote-sensing retrievals of aerosol particles and fog with detailed in-situ measurements. Therefore, during winter and spring 2021/22, we conducted the Fog and Aerosol InteRAction Research Italy (FAIRARI) campaign at the research station SPC. We measured processes on the scale of gas molecules up to droplets and captured not only the wintertime fog period but also the springtime new particle formation period and the transition, which was associated with an increase in the air temperature and global radiation, as well as a decrease in PM2.5 concentration. We found a large variability in the microphysical characteristics of the fog events, which lasted between a few minutes and 13 hours. While the dry aerosol mostly consisted of particles around 100 nm, the droplets grew to diameters around 20 μm. Organics and nitrate dominated the dry mass of the measured submicron chemical composition. In the fog residuals, nitrate and sulfate fractions were enhanced, whereas the organic aerosol fraction was reduced compared to the ambient aerosol during non-fog conditions. Notably, the organics present in the fog residuals showed a higher relative contribution of organic nitrogen, potentially resulting from aqueous-phase fog processing. Moreover, we provide new κ-values for several organic compounds and show that a value of 0.1 reliably estimates their hygroscopicity in both supersaturation-limited (Po Valley) and particle-limited (Arctic) environments. The high amount of nitrate found in the Po Valley led to an overall high hygroscopicity of the particles. The high number concentration of accumulation mode particles in combination with high hygroscopic growth factors make hygroscopically grown - but not activated - particles important for various reasons: These hydrated aerosol particles do not only reduce visibility through scattering but also influence the interpretation of aerosol-fog relationship measurements. For example, the effective diameter of the droplets increases by 81 % when excluding hydrated aerosol particles, while the cloud droplet number concentration decreases by 87 %. The contribution of hydrated aerosol particles to the liquid water content was shown to be dependent on the accumulation mode number concentration and the supersaturation. Moreover, not the total number concentration but the shape of the upper tail of the dry particle number size distribution was shown to be crucial when predicting fog microphysical parameters using Large Eddy Simulations. Additionally, hydrated aerosol particles impact the physical and chemical measurements of interstitial aerosol and fog residuals as those are defined by ambient diameter thresholds which are lower than the largest hydrated aerosol particles. This thesis emphasizes the importance of aerosol chemical composition and particle size in determining aerosol-cloud and aerosol-fog behavior across contrasting environments. It highlights the role of fog and aqueous-phase processing in transforming aerosol properties and affecting visibility, climate-relevant fog parameters, and potentially human health.ERC INTEGRATEH2020 FORCe

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.
