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
Analysis of the Selected Workplace in the Selected Company
No full textTato bakalářská práce se zabývá analýzou vybraného pracoviště s využitím metod přímého měření a pozorování, návrhem metod 5S a SMED pro zlepšení jeho efektivity a produktivity. Provedená analýza ukázala, že většina strojů na pracovišti trpí nevyhovujícím stavem pracovních skříní, což zvyšuje riziko růstu času přestaveb. Další zjištění práce ukázala, že stroj correanyak versa M je nejvhodnějším strojem pro aplikaci metody SMED, z důvodu velké příležitosti snížení nákladů. Hlavním závěrem této práce je, že dochází k extrémnímu plýtvání časem při přestavbě stroje, které je způsobeno neadekvátní organizací práce operátora a pomocným operátora. Tento zjištěný problém by měl být vyřešen pomocí implementace metod 5S a SMED, což přinese snížení nákladů a zlepší efektivitu a výkonnost pracoviště. Výsledky této práce jsou návrhy pro zlepšení procesů na pracovišti a mohou sloužit jako podklad pro další výzkum a optimalizaci pracovních procesů ve vybraném průmyslovém podniku.This bachelor's thesis deals with the analysis of a selected workplace using direct measurement and observation methods, as well as proposing 5S and SMED methods to improve its efficiency and productivity. The analysis revealed that most machines at the workplace have inadequate work cabinets, which increases the risk of increased changeover time. Additionally, the study showed that the Correanyak Versa M machine is the most suitable for implementing the SMED method due to its significant cost-reduction potential. The main conclusion of this work is that there is extreme time waste during changeover, which is caused by the inadequate organization of work between the operator and assistant operator. This identified problem should be addressed by implementing the 5S and SMED methods, which will reduce costs and improve the efficiency and performance of the workplace. The results of this work are proposals for improving processes in the workplace and can serve as a basis for further research and optimization of work processes in the selected industrial enterprise.Ústav průmyslového inženýrství a informačních systém

Rationalization of the Production Line in the Selected Company
No full textTato diplomová práce se zabývá analýzou výrobní linky na montáž wastegate ventilů ve vybrané společnosti. Cílem práce je identifikovat úzká místa na výrobní lince, analyzovat jejich vliv na její kapacitu a navrhnout opatření vedoucí ke zvýšení efektivity výroby. V rámci praktické části byla provedena detailní analýza cyklových časů jednotlivých operací, přičemž hlavní úzká místa byla nalezena u operací testování těsnosti, zajištění víka a aplikace maziva. Na základě získaných dat byly navrženy varianty řešení, které byly vyhodnoceny pomocí multikriteriální analýzy. Výsledkem práce je doporučení kombinace instalace třetího leak testeru a optimalizace montážních operací za účelem zvýšení propustnosti linky a snížení rizika výrobních prostojů.This diploma thesis focuses on the analysis of a production line for assembling wastegate valves in a selected manufacturing plant operating in the automotive industry. The aim of the thesis is to identify bottlenecks on the production line, analyze their impact on the line's capacity, and propose measures to increase its efficiency. In the practical part, a detailed analysis of cycle times of individual operations was carried out, with the main bottlenecks identified in leak testing, cover securing, and grease application operations. Based on the collected data, solution variants were proposed and evaluated using a multi-criteria analysis. The outcome of the thesis is a recommendation to combine the installation of a third leak tester and the optimization of assembly operations in order to increase the line throughput and reduce the risk of production downtimes.Ústav průmyslového inženýrství a informačních systém
