Algorithmic thinking and its development in primary school
No full textCílem bakalářské práce, bylo analyzovat nový RVP ZV 2021 a ŠVP vybraných škol v Plzni. Následně vytvořit dotazník a poslat ho do škol, kterým byl ŠVP analyzován, abychom získali přehled o tom jak Informatika a její výuka vypadá po revizi na základních školách. Jako poslední byla vytvořena aktivita, která žákům může pomoci rozvinout jejich algoritmické myšlení a zároveň jim ukázat, že Informatika nemusí být pouze sezení u počítače.ObhájenoThe aim of the bachelor thesis was to analyse the new educational framework programme 2021 and the curriculum of selected schools in Pilsen. Subsequently, we created a questionnaire and sent it to the schools whose curriculum was analyzed in order to get an overview of how Computer Science and its teaching looks like after the revision in primary schools. Lastly, an activity was created that can help pupils develop their algorithmic thinking and at the same time show them that Informatics does not have to be just sitting in front of a computer
Porovnání hybridních sklízecích mlátiček Claas Lexion 8700 TT a Claas Lexion 770
No full textThis bachelor thesis deals with the comparison of Claas Lexion 770 and Claas Lexion 8700 TT hybrid combine harvesters. These machines are compared in the thesis in terms of losses, fuel consumption, economic parameters, performance and throughput. The result of the comparison of economic parameters is a turning point diagram, which determines which combine harvester pays off depending on the hectares harvested. The turning poing diagram also shows a comparison of whether it is worthwhile for the enterprise to own the harvester or whether it is more profitable for the enterprise to hire harvesting services. All the information and documents needed for this comparison were collected during the harvesting season at AGRO, družstvo Záhoří and were obtained through a number of experiments during the work of the harvesters. As the machines are similar in terms of performance, this work is also intended as a comparison of the improved threshing system of the Claas Lexion 8700 TT with the older system of the Claas Lexion 770
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
