Mobile Exam System – MES: Architecture for Database Management
No full textAs the mobile applications are constantly facing a rapid development in the recent years especially in the academic environment such as student response system (Lópeza, Royoa, Labordab & Calvoa, 2009; Ngai & Gunasekaran, 2007; Mary & Biju, 2008; Nayak & Erinjeri, 2008; Roth, Ivanchenko & Record, 2008; Lu, Stav & Pain, 2009; Lu, 2009; Turning technologies, 2010) used in universities and other educational institutions; there has not been reported an effective and scalable Database Management System to support fast and reliable data storage and retrieval. This paper presents Database Management Architecture for an Innovative Evaluation System based on Mobile Learning Applications. The need for a relatively stable, independent and extensible data model for faster data storage and retrieval is analyzed and investigated. It concludes by emphasizing further investigation for high throughput so as to support multimedia data such as video clips, images and documents
International Conference ‘Roman Ivanchenko Scientific School’
No full textThe aim of the conference ‘Roman Ivanchenko Scientific school’ is a professional discussion of current issues, discussions of professional and educational issues, fostering young scientists. From 2009 to 2016 it acquired the status of the International Ukrainian conference. It was visited not only by Ukrainian scholars from nearly 30 universities ofUkraine, but also by scholars from abroad, includingGermany,Poland,Belarus. In addition to Ph.D’s and professors, scientific presentations at the conference recite graduated masters and bachelors.
The sections of the conference cover the history and theory of publishing and editing, topical issues of Ukrainian books publishing, culture publications, personalities of Ukrainian books publishing, especially mass modern communication, new technologies in the preparation of media products, editing different types of books, advertising and PR communications in printing, publishing, books distribution, the issue of education for future editors, journalists etc. Each year, the conference marked the memory of the great scientist R. H. Ivanchenko with dedication and thematic round tables.
Conference proceedings are published in printed/electronic form. The books are presented during the conference and there are performances by guests — practitioners publishers, writers and journalists.
The conference ‘Roman Ivanchenko Scientific school’ is a powerful tool of scientific and educational communication, because of discussing, systematizing, summarizing materials, scientific findings and research results, emerging circle of associates, who generated new ideas, projects, interdisciplinary ideas and so on. The conference is characterized by urgency, informative, debatable, creative collaboration etc., promotes new ideas, knowledge, and discoveries in the field.
An important thing in format of conference is a senior research co-generation of talented young people (students work on scientific articles under the guidance of Ph.D’s, performances of students for authoritative audience), exchange of experience, ‘master classes’ in the flesh
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
Features of intellectual functions inhibition among Ukrainian boxers: A sociocultural study
No full textThe effects of boxing's extreme aggressive conditions in training and competitive activity in sportsmen’s mental working capacity still remains under-explored. While the neurophysiological effects caused by micro traumas to the brain have been extensively studied, less attention has been paid to the psychological consequences. This article reports on our study of the features of mental operations efficiency in Ukrainian boxers. The study involved athletes (n = 168, gender: men, average age: 25.5 ± 6.2 years), who were engaged in boxing and kickboxing in the Ukraine’s eastern region. A ‘Classification’ method was used: a set of 70 cards with the images of various objects, plants, and living beings was given with instructions to arrange the items into groups in such a way that the objects in each concrete group possess common properties. Athletes were divided into groups, depending on the level of their sport qualification. Adopting the Vygotskian perspective, this study shows correlations between the productivity of boxers’ thinking processes and the level of their sport skills: highly qualified sportsmen have many more well-marked thinking process defects than the sportsmen of the 2nd and 3rd categories. We observed a decrease in the generalization level, reduction in speed, deterioration of neurodynamic characteristics and criticality processes nearly in all participants. Exhaustibility and decrease in mental working capacity, impulsiveness of thinking, and its unproductive transformation were marked more often among the highly skilled boxers. A discussion on the cultural redefinition of this sport and on the necessary rehabilitative treatments is then presented
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
The Thursday Murder Club: Launching a megabrand author - a publishing case study
No full textIn 2020, the Christmas book charts in the UK made headlines: Barack Obama’s eagerly awaited autobiography, The Promised Land, was beaten to the top spot by The Thursday Murder Club by Richard Osman, a debut cosy crime novel set in a retirement village. Not only did Osman’s book beat the former US president’s expected bestseller, it also broke records, becoming the fastest-selling debut crime novel of all time. Although Osman has a certain level of fame in the UK from his TV appearances on shows such as Pointless, his celebrity status does not entirely explain the novel’s huge sales. This article tracks the acquisition, publication, and promotion journey of The Thursday Murder Club in order to understand the industry and cultural context of its success and to interrogate the role of celebrity in the creation of author brands. The findings suggest that the unexpected scale of the success of the book owed to a number of factors, including in-depth editing by the novel’s agent, editor, and author to tighten up the plot, an extensive and strategic promotional campaign, the pandemic (which drove interest in the book’s genre and themes), and the quality of the writing. We find that the book’s success was accentuated by Osman’s celebrity status rather than being entirely reliant on it. This research adds to the growing scholarship on celebrity authorship by means of an in-depth case study and provides insight into the processes behind publishing a ‘celebrity’ book and launching a megabrand author
Cellular and molecular factors in the pathogenesis of systemic autoimmunity and comorbidities
No full textSjögren’s syndrome (SS) and systemic lupus erythematosus (SLE) are systemic rheumatic autoimmune diseases having a major impact on patient’s wellbeing. Besides fatigue, pain and direct damage to exocrine glands in SS, and various target organs, such as skin, joints, kidneys and brain in SLE, these diseases confer an increased risk of lymphoma development and can cause an autoimmune condition in the foetus of pregnant patients, termed neonatal lupus.Several cell types and cytokines contribute to the autoimmune process, with central roles for B cells and autoantibodies. Mature B cells are attracted to the sites of inflammation by chemokine CXCR5. Recent studies identified CXCR5 as a susceptibility gene in SS, and a decrease in expression of CXCR5 on circulating B cells in SS patients, however, the link between the polymorphisms in the CXCR5 locus and B cell trafficking wasn’t addressed. We therefore explored the expression of the chemokine on lymphocytes in peripheral blood and minor salivary glands in SS patients. Confirming the previous findings, our results demonstrate reduced CXCR5 expression in circulating B cell pool, coinciding with the accumulation of CXCR5-positive cells in the salivary glands of the patients. We conclude that the observed decrease in CXCR5 expression in SS results from relocation of CXCR5-highly-positive B cells from blood stream to the salivary glands.T follicular regulatory (TFR) cells also express CXCR5, and the frequency of circulating TFR was suggested a biomarker of degree of tissue inflammation and autoantibody production in SS and rheumatoid arthritis. We could confirm the elevated frequencies of TFR in the blood of SS patients, and show that most of them have a naïve phenotype. B cells are producers of the SS hallmark autoantibodies against Ro and La, that have been used for diagnostic purposes for decades. In this thesis we investigated the anti-inflammatory and anti-proliferative properties of TRIM21/Ro52, one of the targets of anti-Ro. We studied the role of Trim21 in the homeostasis of mouse B cells, and the relevance of TRIM21 as a prognostic marker in diffuse large B-cell lymphoma. In Trim21 knockout mice, B cells had a higher rate of proliferation, follicular B cells were expanded and higher levels of both IgM and IgG were generated after immunization with both thymus dependent and independent antigens engaging the B cell receptor. In accordance with these data, maintained TRIM21 expression was associated with a better prognosis in diffuse large B-cell lymphoma, independently of subtype and underlying autoimmune disease.Another severe comorbidity in SS and SLE affects foetuses and newborns of the patients. Maternal Ro and La autoantibodies are transferred to the developing foetus, and in 2% cases this leads to a congenital heart block (CHB), a part of neonatal lupus. Here, we studied signs of inflammation in the cord blood of neonates exposed to maternal anti-Ro/La. We observed an elevation of serum type I interferon (IFN) levels and an IFN-gene signature in autoantibody-exposed neonates. Besides, neonatal PBMC proved to be capable to produce IFN in vitro, suggesting a possible foetal origin of the cytokine. Further, we show increased frequencies of circulating natural killer cells, and presence of type II IFN in the sera of some of these newborns. These novel findings contribute to the understanding of the mechanisms behind CHB.In summary, we connect genetic variants of the CXCR5 gene locus to expression patterns and cell compartmentalization in SS, demonstrate a role of the autoantigen TRIM21 in B cell homeostasis and function and present evidence for innate immune activation in Ro and La autoantibody-exposed newborns.List of scientific papersI.
