A Menon-type identity using Klee's function
summary:Menon's identity is a classical identity involving gcd sums and the Euler totient function . A natural generalization of is the Klee's function . We derive a Menon-type identity using Klee's function and a generalization of the gcd function. This identity generalizes an identity given by Y. Li and D. Kim (2017)
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Recasting European Welfare States
The chapter presents, in synthesis form, some key elements of what is now understood about welfare regimes, their respective pathologies of development, their current paths of reform, and the challenges that still confront them. The first section examines welfare state performance thematically, focusing on employment, the scale and shape of social security systems, and distributive outcomes. The second section takes Europe's four welfare regimes (those of Scandinavia, the United Kingdom, continental Europe and Southern Europe) and analyses their respective strengths and vulnerabilities. The conclusion considers where the literature on welfare states is likely to go in the future
ESPRESSIONE DEI RECETTORI TOLL-LIKE IN ORGANI MURINI ADULTI ED EMBRIONALI
Toll-like receptors (TLRs) are members of a conserved family of type I transmembrane proteins that play a key role in innate immunity through their function as Pattern Recognition Receptors (PRRs) that detect microbial and non-microbial components known as Microorganism Associated Molecular Patterns (MAMPs).In mammals, TLRs are widely expressed in many cell types, including nervous cells and epithelial and endothelial cells of hollow and parenchymatous organs.
Having demonstrated in a previous study the expression of TLR4 and TLR7 in the enteric nervous system (ENS) and dorsal root ganglia (DRGs) of human and murine adults, the aim of the present study was to investigate if their expression is already present during murine peripheral nervous system and other parenchymatous organs (adrenal gland, liver and pancreas) development and to compare with adult pattern of expression
Dispelling the Myths Behind First-author Citation Counts
We 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
We 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
