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
Electroinduced Surfactant Self-Assembly Driven to Vertical Growth of Oriented Mesoporous Films
No full textConspectusSupramolecular soft-templating approaches to
mesoporous materials
have revolutionized the generation of regular nanoarchitectures exhibiting
unique features such as uniform pore structure with tunable dimensions,
large surface area, and high pore volume, variability of composition,
and/or ease of functionalization with a wide range of organo-functional
groups or good hosts for the in situ synthesis of
nano-objects. One appealing concept in this field is the development
of ordered mesoporous thin films as such a configuration has proven
to be essential for various applications including separation, sensing,
catalysis (electro and photo), energy conversion and storage, photonics,
solar cells, photo- and electrochromism, and low-k dielectric coatings for microelectronics, bio and nanobio devices,
or biomimetic surfaces. Supported or free-standing mesoporous films
are mostly prepared by evaporation induced self-assembly methods,
thanks to their good processing capability and flexibility to manufacture
mesostructured oxides and organic–inorganic hybrids films with
periodically organized porosity.One important challenge is
the control of pore orientation, especially
in one-dimensional nanostructures, which is not straightforward from
the above evaporation induced self-assembly methods. Accessibility
of the pores represents another critical issue, which can be basically
ensured in the event of effective interconnections between the pores,
but the vertical alignment of mesopore channels will definitely offer
the best configuration to secure the most efficient transfer processes
through the mesoporous membranes. The orthogonal growth of mesochannels
is however not thermodynamically favored, requiring the development
of methods enabling self-organization through nonequilibrium states.
We found that electrochemistry afforded a real boon to tackle this
problem via the electrochemically assisted self-assembly (EASA) method,
which not only provides a fast and versatile way to generate highly
ordered and hexagonally packed mesopore channels but also constitutes
a real platform for the development of functionalized oriented films
carrying a wide range of organo-functional groups of adjustable composition
and properties.This Account introduces the EASA concept and
discusses its development
along with the significant progress made from its discovery, notably
in view of recent advances on the functionalization of oriented mesoporous
silica films, which expand their fields of application. EASA is based
on the in situ combination of electrochemically triggered
pH-induced polycondensation of silica precursors with electrochemical
interfacial surfactant templating, leading to the very fast (a few
seconds) growth of vertically aligned silica walls through self-assembly
around surfactant hemimicelles transiently formed onto the underlying
support. This method benefits from the possibility to deposit uniform
thin films onto surfaces of different natures and complex morphologies
including at the microscale. From this discovery, our research expanded
to cover domains beyond the simple production of bare silica films,
turning to the challenge of incorporation and exploitation of organo-functional
groups or nanofilaments. So far, the great majority of methods developed
for the functionalization of mesoporous silica is based on postsynthesis
grafting or co-condensation approaches, which suffer from serious
limitations with oriented films (pore blocking, lack of ordering).
We demonstrated the uniqueness of EASA combined with click chemistry
to afford a versatile and universal route to oriented mesoporous films
bearing organo-functional groups of multiple composition. This opened
perspectives for future developments and applications, some of which
(sensing, permselective coatings, energy storage, electrocatalysis,
electrochromism) are also considered in this Account
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.
