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
WYMIANA HANDLOWA MAŁYCH I ŚREDNICH PRZEDSIĘBIORSTW W PROCESIE KONWERGENCJI
Get PDFThe accession of Poland to the Euro Zone is a necessary, strategic condition, causing far-reaching consequences for the economy as a whole, but also for individual market participants. The purpose of this article is to show the nature of the commercial activity of small and medium size enterprises (SMEs) in the context of the impact of Polish accession to the euro zone trade with third countries and EU Member State. The analysis goal is to indicate if the introduction of common currency affects the size of SMEs’ trade with the countries of the European Union, the Schengen area and the euro area.Keywords:euro zone, import, export, European Union, foreign tradePrzystąpienie Polski do strefy euro jest warunkiem koniecznym, strategicznym, a zarazem powodującym daleko idące konsekwencje zarówno dla gospodarki jako całości, ale też poszczególnych uczestników rynku. Celem artykułu jest pokazanie charakteru działalności handlowej małych i średnich przedsiębiorstw (MSP) w kontekście wpływu przystąpienia Polski do strefy euro na ich wymianę handlową z państwami trzecimi oraz członkowskim Unii Europejskiej. Zaprezentowano studia literatury, przeprowadzono analizę zastanych danych oraz przedstawiono wyniki badań ankietowych przeprowadzonych w 2013 roku wśród małych i średnich przedsiębiorstw w województwie podlaskim
Innovation types at SMEs and external influencing factors
No full textStimulating innovation is one of the pressing policy challenges facing many countries in the world today. The paper analyses the external factors that Polish entrepreneurs find most detrimental to their innovative activity. A sample of 199 small and medium size enterprises (SMEs) in Poland were subjected to a survey. The data collected revealed the innovation types of SMEs in Poland and external financial factors influencing innovation the most. The results show external factors such as legal regulations, access to external financing, bureaucracy of institutions, financial government support, the tax system, time necessary to comply with regulations, and crisis and instability are very important for SMEs. According to the results, process and marketing innovations are applied more frequently than product and organisational innovations. Finally, the results indicate that entrepreneurs indicate that lack of government support and weakness of tax incentives is an important barrier to the innovation process
Mapowanie strategii kapitału obrotowego netto w sektorze energetycznym w Polsce – perspektywa transformacji
No full textCelem artykułu jest identyfikacja strategii zarządzania kapitałem obrotowym netto stosowanych w sektorze energetycznym. Analizą objęto wszystkie spółki notowane na Giełdzie Papierów Wartościowych w Warszawie w ramach indeksu branżowego WIG-Energia. Badanie zostało przeprowadzone na podstawie raportów finansowych za lata 2022-2023, przy czym w mapowaniu strategii wykorzystano dane z ostatnich raportowanych kwartałów, tj. Q1 i Q2 roku 2023. Zastosowano metodę analizy wskaźnikowej w odniesieniu do wskaźników branżowych oraz uwzględniono dynamikę zmian badanych wskaźników. Wyniki badań wskazują, że obecnie podmioty energetyczne stosują głównie strategie agresywne (64%). Prognoza kapitału obrotowego netto sektora wskazuje, że silny trend wzrostowy, który obserwujemy od 2020 r., od 2023 r. zacznie stopniowo zwalniać. W wyniku zastosowania techniki mapowania wskaźnikowego można zauważyć znaczną koncentrację wskaźników w sektorze, przy czym tylko dwa podmioty różnią się pod tym względem od reszty sektora.The aim of the article is to identify net working capital management strategies used in the energy sector. The analysis covered all companies listed on the Warsaw Stock Exchange under the WIG-Energy industry index. The study was conducted on the basis of financial reports for 2022-2023, with data from the latest reported quarters, i.e. Q1 and Q2 of year 2023, used in strategy mapping. The ratio analysis method was used with reference to industry indicators, and the dynamics of changes in the examined indicators was taken into account. The research results indicate that currently energy entities mainly use agressive strategies (64%). The sector's net working capital forecast indicates that the strong growth trend that has been seen since 2020 will gradually begin to slow down from 2023. As a result of using the indicator mapping technique, significant concentration of indictors can be noted in the sector, with only two entities differing from the rest of the sector in this regard
