Katowice Division (1975)
W dniu 1 października 1968 roku w Hali Parkowej w Katowicach odbyła się uroczysta inauguracja
I roku akademickiego w Alma Mater Silesiensis. Pięć lat później (1973 r.) na „młodym” jeszcze
Uniwersytecie Śląskim utworzono trzy nowe Wydziały, m.in. Wydział Biologii i Ochrony Środowiska.
To z inicjatywy pracowników naukowych tego właśnie Wydziału, 5 listopada 1975 roku powołano
do życia Oddział Śląski PTB, którego siedziba trwale i niezmiennie związana jest z Katowicami
i Uniwersytetem Śląskim.
W 45-letniej historii Oddziału Śląskiego największą aktywnością pod względem naukowym
i organizacyjnym wykazali się m.in. profesorowie: Beata Babczyńska-Sendek, Stanisław Cabała,
Florian Celiński, Zygmunt Hejnowicz, Krzysztof Jędrzejko, Tadeusz Kimsa, Henryk Klama, Ewa
Kurczyńska. Jolanta Małuszyńska, Tadeusz Przybylski, Adam Rostański, Krzysztof Rostański,
Andrzej Sendek, Adam Stebel, Barbara Tokarska-Guzik, Stanisław Wika, przyczyniając się tym
samym do jego rozkwitu, jak również rozwoju całego Towarzystwa Botanicznego
Intentional introduction of Biscutella laevigata L. on the post-flotation lead-zinc ore spoil heap in Piekary Śląskie (Upper Silesia, Southern Poland)
The paper presents an account of the successful intentional introduction of the mountain species Biscutella laevigata to a lowland locality, as a result of field experiment - biological management at the toxic “Dołki” washery spoil heap (Lead and Zinc Ore Main and Factory) ZGH “Orzeł Biały” (Upper Silesia – Southern Poland). The aim of the presented study was to test the effectiveness possibilities of using the blend of seeds including a metallophyte – Biscutella laevigata seeds. The introduction of Biscutella laevigata was a part of an experiment which began in 2009-2010 with plots on the "Dolki" washery spoil heap. The tested seeds of Biscutella laevigata were examined for germination, growth and development in sites highly polluted with heavy metals. Biscutella laevigata appeared on two experimental plots. After 4 years there were numerous individuals of Biscutella – dozens of plants in various stages of development and phenology. Development of a Biscutella population from year to year (2 plants in 2010 – 58 plants in 2014) is larger and tends to increase. Biscutella individuals are spreading outside the designated test plots. The obtained results indicate that on sites highly polluted with heavy metals it is possible to perform a successful introduction of Biscutella laevgata population (increase from 2 individuals in 2010 to 58 individuals in 2014) from seeds. These results are also promising in terms of application as a new reclamation method
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
