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
Production of supramolecular aggregates by microfluidic platforms: application to food industries
No full textThis chapter highlights the potential uses of microfluidics for the preparation of SAs and other MNS, including polymeric nano- and microparticles, for food products. Advances in food science and technology have dictated the need for developing more robust and controllable procedures for the production of MNS. Standard procedures rely on bulk mixing and are generally associated with poor batch-to-batch reproducibility and problems in fast screening aimed at optimizing the MNS properties.
In this respect, microfluidics offers the ability to produce MNS in a controllable and reproducible manner, offering a possible solution to the aforementioned drawbacks. Unfortunately, when comparing the intense research in the study of MNS for biomedical applications, relatively little has been done for the design and production of MNS for food and agricultural applications. Considering its high potential in food science, the use of microfluidic-based reactors for the production of various MNS as delivery systems should increasingly attract the attention of researchers involved in food science and industrial applications.
The fluid environment in the microfluidic domain has been understood to have important implications for MNS production. Notably, unique features make microfluidics an appealing technique for MNS production, including: (1) controllable and efficient mixing, resulting in a homogeneous reaction environment; (2) a great control of the reaction; (3) in situ monitoring of the entire process for the production of MNS; (4) tuning of the final characteristics of produced MNS by controlling the kinetics of the process; and (5) the possibility to integrate postsynthetic procedures and measurements in a single microfluidic device.
These features have been leveraged by some research groups for the production of different categories of MNS, including nanoparticles, polymeric microparticles, liposomes, and emulsions. However, despite this activity and the encouraging results obtained so far, the field of microfluidic production of MNS for food applications remains at an early stage. Microfluidic-mediated preparation procedures have the potential to become a standard production tool for the food industry with an unprecedented degree of controllability and homogeneity.
It is opinion of these authors that various aspects should be addressed in the near future to advance this technology. One of the most relevant open problems in microfluidics is related to the low production capacity for MNS. This lack is largely due to the microscale dimension of the chip channels and the related restriction to operate the chips at high flow rates, due to the increase in pressure drop across the microchannels with the increasing flow rate of the pumped fluids. Various strategies to solve this limitation could be proposed, such as new microchip designs where either microvortices, jet-impact, or multilamination strategies could be included.
It is expected that in the future more researchers will try to address this challenge, because it represents one of the most important issues which hinder the use of microfluidic devices for food industrial applications. For instance, another possible solution to the low productivity of microfluidic approaches could be represented by the implementation of par- allelization strategies, in which the individual functional units are repeated in parallel chips. However, it is difficult to ensure identical operation conditions for each unit, thus sometimes resulting in lower control of the MNS properties.
In conclusion, despite the fact that the use of microfluidics for production of MNS for food applications is not yet a mature industrial applicable procedure, research carried out in recent years has demonstrated that microfluidics could represent a great opportunity for the controlled preparation of MNS for food ingredient purposes, offering a great op- portunity to improve the tuning of their properties. Considering the rapid growth of the fields of functional foods, nutraceuticals, and microfluidics, the efforts at increasing the knowledge at their intersection are likely to provide new and exciting perspectives for tailoring the properties of MNS through controlled microfluidic preparation
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.
