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
Structural, Dynamic, Elastic and Electronic Properties of ANiN (A = Li, Na, Mg, Ca): First-Principles Calculations
No full text三元过渡金属氮化物ANiN (A = Li, Na, Mg, Ca)是潜在的可充放电池的电极材料。物理性质,比如热稳定性、电子能隙以及弹性稳定性等,对于这些材料的电池应用都是非常重要的。本文使用第一原理方法,对比研究了ANiN这些材料的结构、动力学、弹性和电子结构性质。对状态方程和声子谱的计算被用来确定体系的稳定结构。对最稳定结构的弹性常数的计算表明,这些稳定结构都满足 Born-Huang的稳定性判据,意味着它们的弹性稳定性。对体系电子结构的计算表明,LiNiN和CaNiN是半金属（half-metals）,MgNiN是磁性材料,而NaNiN是通常的金属。这些材料的磁学性质都通过Stoner理论进行了解释。最后,电荷密度的计算被用来很好地说明了这些材料中的Ni-N成键的特征,表明成键特点主要是离子性的,但明显地混合了共价性。Ternary transition metal nitrides ANiN (A = Li, Na, Mg, Ca) are potential electrode materials for rechargeable batteries. The physical properties, such as the thermodynamic stability, the electronic band gap as well as the elastic stability, are important for their battery applications. Here, comparative studies are performed for the structural, dynamic, elastic and electronic properties of ANiN by the first-principles method. The calculations on the cohesive energy versus unit-cell volume and phonon spectra are employed to determine the most stable structures of ANiN. The calculated elastic constants of the most stable structures indicate that the Born-Huang criterion for the elastic stability can all be satisfied, showing the elastic stability of the materials. The electronic structures calculations suggest that LiNiN and CaNiN are half-metals, MgNiN is magnetic metal, while NaNiN is a common metal. The magnetization of the materials is understood by the Stoner theory. Furthermore, the charge density plots have been used to illustrate the bonding between Ni and N atoms, which is mainly ionic mixed with covalent.通讯作者:朱梓忠E-mail:[email protected]:Zi-ZhongZhuE-mail:[email protected].厦门大学物理科学与技术学院,福建 厦门 3610052.厦门大学固体表面物理化学国家重点实验室,福建 厦门 3610053.厦门大学福建省理论和计算化学重点实验室, 福建 厦门 3610051.

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.
