CORPORATE AND SECTOR INFLUENCES ON FIRM PERFORMANCE: EVIDENCE FROM POLAND
Get PDFThe study examines the impact of firm- and industry-level variables on performance of Polish listed companies. The study is based on the data of companies (all but financial and commercial ones) listed on the Warsaw Stock Exchange in the period of 2007-2012. Each of the companies has also been classified into a specific industry according to the Polish PKD classification (similar to NACE Rev.2). The study employed panel data analysis with fixed effects. The results indicate that the firm-level effects have a slightly stronger impact on companies\u27 performance than industry-level effects, though the differences largely depend on the model applied to research. In the 1st panel (dependent variable ROA) the results indicate around three times higher impact of firm- in comparison to industry-level effects. In the 2nd panel (dependent variable ROS) the difference between these two types of variables is approximately 15%
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
Uwzględnienie zagadnień geopolityki i geostrategii w analizach strategicznych
Get PDFThe main goal of the article is to answer the question whether and how to extend classic strategic analyzes to include geopolitics and geostrategy issues. Both of these terms are of particular importance when building possible strategic analyzes for major strategic projects in Poland. This applies, for example, to projects such as the Solidarity Transport Hub Poland, the construction of a nuclear power plant, or the development of transport connections. Also, issues related to national defense, both in the “hard” (army, military equipment) and “soft” aspects (e.g. cyber defense, development of Polish microelectronics), are largely linked to issues of geopolitics and geostrategy. Meanwhile, in the conditions of the domestic literature on the subject, these issues have not been the subject of serious scientific interest, hence a clear research gap in this respect can be observed. Therefore the task of the is to, at least partially, reduce this gap.Podstawowym celem opracowania jest próba odpowiedzi na pytanie, czy i w jaki sposób należy rozszerzyć klasyczne analizy strategiczne o zagadnienia geopolityki i geostrategii. Oba te terminy nabierają szczególnego znaczenia przy budowaniu ewentualnych analiz strategicznych dla najważniejszych projektów strategicznych, w tym w warunkach Polski. Dotyczy to przykładowo takich projektów jak Centralny Port Komunikacyjny, budowa elektrowni jądrowej czy też rozbudowa połączeń komunikacyjnych. Również zagadnienia związane z obronnością kraju, zarówno w aspekcie „twardym” (armia, sprzęt wojskowy), jak i „miękkim” (np. cyberobrona, rozwój polskiej mikroelektroniki), są w znacznym stopniu powiązane z zagadnieniami geopolityki i geostrategii. Tymczasem w warunkach krajowej literatury tematu problematyka ta nie była dotąd przedmiotem poważnego zainteresowania naukowego, stąd można zaobserwować wyraźną lukę badawczą w tym zakresie. Tematyka podjęta w rozdziale będzie miała za zadanie lukę tę zmniejszy
