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

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
Die Liberalisierung der Wohnungspolitik in Polen und ihre sozialräumlichen Auswirkungen: das Beispiel Poznań
Get PDFZahlreiche polnische Großstädte, welche Jahrzehnte lang unter einer Wohnungsnot gelitten hatten, erleben seit der Jahrhundertwende einen Wohnungsbauboom. Das Angebot an neu gebauten Wohnungen hat enorm zugenommen, die Wohnkosten sind rasch gestiegen. Dieser Aufschwung wurde vor allem durch einen hohen Anteil von Menschen im Alter der Haushaltsgründung, den Zuzug junger Menschen aus dem ländlichen Raum, die steigende Kaufkraft der Bevölkerung sowie durch die wachsende Rolle der Projektentwickler verursacht. Im folgenden Beitrag werden die sozialräumlichen Auswirkungen des "Wohnungsbooms" am Beispiel der Stadt Poznań (Posen) analysiert. Die fünftgrößte Stadt Polens hat 557.000 Einwohner, darunter zahlreiche junge Leute und Studenten. Allein im Jahre 2008 wurden in Poznań rund 3.300 neue Wohnungen fertig gestellt. In der wesentlich größeren deutschen Hauptstadt Berlin gab es im Vergleich dazu im selben Jahr nur rund 3.800 Baufertigstellungen. Aufgrund der Wirtschaftskrise ist die Wohnungsnachfrage in Poznań gegenwärtig zwar gesunken, langfristig jedoch ist weiterhin Wachstum zu erwarten. Durch des "Wohnungsbooms" verändert sich die Struktur der Stadt. Im Zeitraum von 1999-2008 hat sich der Wohnungsbestand von Poznań um fast 15% vergrößert. Neue Wohnkomplexe entstehen im ganzen Stadtgebiet: in der Innenstadt, in den Großsiedlungen und vor allem am Stadtrand. Aufgrund der hohen Preise nehmen sowohl Segregations- als auch Suburbanisierungsprozesse zu. Der Wohnungsbauboom ist eine Herausforderung für die Stadtentwicklungspolitik - vor allem für die Verkehrs- und Infrastrukturplanung. (Autorenreferat)Many Polish cities, which for decades have suffered under housing shortage, experience since the turn of the century a housing boom. Both the supply of new dwellings, as well as housing prices have risen rapidly. This upturn was caused mainly by the high share of people in matrimonial age, the infl ow of young people from rural areas, the growth of purchasing power, and the growing role of property developers. The following paper describes the socio-spatial impact of housing boom on the example of the city of Poznań. It is the fifth-largest city in Poland with 557,000 inhabitants, including many young people and students. Only in the year 2008 approximately 3,300 new dwellings were completed in Poznań. For comparison in Berlin (which is several times larger than Poznań) there were in the same year approximately 3,800 housing completions. Because of the economic crisis, the demand for housing has decreased, yet in the long term one can expect continued growth. Because of the housing boom the structure of the city is changing. In the period 1999-2008 the housing stock of Poznań increased by almost 15%. New housing complexes are built in different parts of the city: in the inner city, in the large housing estates, and especially on the outskirts. Because of the high prices, the segregation and suburbanization processes are increasing. The housing growth is a challenge for urban development policy, particularly for transport and infrastructure planning. (author's abstract
