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
Моделювання системи міжміських пасажирських перевезень
Get PDFThe modern state of modeling of intercity passenger transportation systems is considered. It is determined that the search for various options for technologies of interaction between the society and the transport industry is constantly at the stage of searching for the best possible methods of transportation organization. To assess the proposed scientific approaches, full-scale measurements are carried out on the route flows of passengers on sections of route routes. The approach to modeling intercity passenger route transportation systems is considered as original in the article, taking into account economic, social and organizational components. These components determine the overall efficiency of the transport process. Together with this, the above approach can be improved. To do this, it is desirable to consider in more detail individual subsystems by mode of transport and separately allocate night and day transportation. Practitioners note that with the same parameters of the trip, people feel differently the consequences of a day and night trip. This can lead to different requirements for the transport network as a whole. But the above algorithm allows to take this into account. The means for assessing the performance parameters of the system of routes for passenger transportation systems are explored. The sequence of formation of the transportation system of intercity passenger transport is proposed, which relies on the achievements of science and practice and takes into account the patterns of distribution of transport correspondence between cities from the transport network. The attraction functions between cities are complemented in accordance with the number of inhabitants and purchasing power. New information has been obtained on the modeling of transport route systems for transportation of passengers between cities within the investigated system. This is more advantageous in comparison with analogues due to the consideration of ensuring the social and economic characteristics of the population, the possibility of increasing productivity by optimizing the use of the route network and meeting the economic interests of the transport industry.This is more advantageous in comparison with the analogues due to ensuring the registration of social and economic characteristics of the population of Ukraine, a possible increase in productivity by optimizing the use of the route network, satisfaction of economic interests of the transport industry.Исследованы средства проведения оценки параметров эффективности функционирования системы маршрутов пассажирских транспортных систем.

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
Моделювання пасажирських транспортних кореспонденцій між обласними центрами в Україні
Get PDFPassenger transport system of Ukraine is studied for establishment of passenger correspondence using public routes between regional centers. The results of the analysis of existing methods of passenger correspondence calculation are found the inability to implement them without preliminary investigation of features of the systems and calculation of the actual values of gravity function.Empirical method is applied for establishing the parameters of quantitative index of gravity function. Unlike previous researchers, this approach for calculation of gravity function parameters allows to obtain new knowledge about the studied system. An opportunity to obtain performance parameters of the experimental system without the human factor and at any time is provided without the use of a manual or automated inspection means for passenger correspondence.Research results provide the opportunity to analyze the calculations of intercity passenger correspondence between regional centers of Ukraine on the general transport routes using a gravity model. Previously unknown parameters of gravity function are defined. This allows to predict the passenger correspondence in this system.Исследован процесс предоставления услуг по перевозке пассажиров на маршрутах общего пользования.

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
