Розробка архітектури комп′ютера "Київ" за концепцією адресного методу програмування
No full textThe article is devoted to the history of the origin of high-level programming in Ukraine. The transition from calculations by arithmometers and logarithmic rulers to solving problems on the computer "Kyiv" using pointers and tree-like formats (abstract data types are analogous) is described. The factors that contributed to this transition include: the experience of providing instructions for calculations by arithmometers, and the experience of programming on MESM. As a result a computer "Kyiv" has been developed with a hardware-implemented possibility of high-level programming, invention of the Addressed Programming Language with indirect addressing (pointers), tree formats and declarative capabilities.Hardware-realized demining of pointers in the computer "Kyiv" is one of the outstanding inventions of Ukrainian engineers and mathematicians at the initial stage of the information technologies development. At that time it was significantly ahead of the world technologies. Programming in computer "Kyiv", unlike Plankalkül, could identify and process complex structures. The paper describes the individual applications of the Address Programming Language, which was implemented on many Soviet-made computers and has been used by programmers for more than 20 years. Due to the so-called "Iron Curtain", scientists in the field of programming outside the post-socialist world still do not know about the invention of pointers by Kiev scientists. A textbook describing the Addressed Programming Language was translated into many languages. A monograph with a description of the computer architecture "Kyiv" and of the Addressed Programming Language was translated into English and published in the United States in 1966.Prombles in programming 2021; 4: 103-118Описано поступовий перехід від розрахунків логарифмічними лінійками та арифмометрами до використання мови високого рівня з вказівниками та складними ієрархічними структурами. В статті розглянуто фактори, які сприяли цьому важливому технологічному переходу. Робота відновлює загублену ланку історії виникнення в Україні опосередкованої адресації (вказівників) вищих рангів та складних ієрархічних структур. Надаються підтвердження винайдення вказівників та складних структур даних київськими вченими, описано апаратну реалізацію в комп’ютері "Київ" "штрих-операції" (розіменування вказівників) та операцій задання циклів. У роботі обґрунтовується високорівневість програмування у командах комп’ютера "Київ" шляхом порівняння з мовою програмування високого рівня – Plankalkül.Prombles in programming 2021; 4: 103-11
Invention of a computer "Kyiv" architecture using a concept of Addressed Programming Language

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
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
