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
Inwiefern beeinflusst das Ausmaß der Interaktion und der Unterstützungsleistungen zwischen Unternehmen und einem kaufmännischen Oberstufenzentrum die Zufriedenheit der Betriebe mit der Ausbildung und die Reduktion von vorzeitigen Ausbildungsabbrüchen?
Full text linkDie vorliegende Bachelorarbeit untersucht den Einfluss von Interaktions- und Unterstützungsleistungen zwischen Ausbildungsbetrieben und kaufmännischen Oberstufenzentren (OSZ) auf die Betriebszufriedenheit und die Reduzierung von Ausbildungsabbrüchen. Die duale Berufsausbildung steht durch die digitale Transformation vor neuen Herausforderungen. Mittels einer quantitativen Befragung von 235 kooperierenden Betrieben wurden Daten zu Kontakthäufigkeit, Kooperation, Unterstützungsmaßnahmen, Zufriedenheit und Ausbildungserfolg erhoben und ausgewertet.This bachelor’s thesis examines the influence of interaction and support services between training companies and business training centres (OSZ) on company satisfaction and the reduction of training dropouts. Dual vocational training is facing new challenges as a result of the digital transformation. A quantitative survey of 235 cooperating companies was used to collect and evaluate data on the frequency of contact, cooperation, support measures, satisfaction and training success
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
Potentiale durch den Einsatz von KI in der Bildung - adaptive Lernmaterialien und Lernpfade
Full text linkIn verschiedenen Lebensbereichen hat die Anwendung von Künstlicher Intelligenz (KI) heutzutage bereits an Bedeutung gewonnen. Auch im Bildungssektor existieren diverse Potenziale für den Einsatz von KI, welche jedoch bisher - insbesondere in der schulischen Bildung - nicht in großem Umfang genutzt werden. Diese Arbeit möchte einen Überblick relevanter Anwendungsfelder von KI im Bildungsbereich geben, wobei der Bereich der institutionellen Bildung im Vordergrund steht. Es sollen dabei sowohl die Chancen als auch die Risiken kritisch erörtert werden, wobei potenzielle Barrieren näher beleuchtet werden. Ein besonders vielversprechendes Anwendungsgebiet von KI in der Bildung ist die Personalisierung von Lernprozessen, welche in dieser Arbeit besonders herausgearbeitet werden. Beim personalisierten Lernen werden Lernpfade, Aufgabenstellungen und Feedbackmechanismen individuell auf die Bedürfnisse der Lernenden zugeschnitten. In der Domäne des Spracherwerbs existieren bereits einige Bildungsangebote, die sich der Unterstützung durch KI bedienen. Ein konkretes Fallbeispiel wird herangezogen und sowohl aus didaktischer als auch technologischer Perspektive analysiert. Abschließend wird ein Ausblick auf mögliche Entwicklungen im Bereich der KI im Bildungswesen gewährt, um potenzielle Perspektiven und Szenarien für die Zukunft aufzuzeigen.The use of AI has already gained importance in various areas of life. There are various potentials for the use of AI in the education sector, but these are not yet being used to any great extent. This paper aims to provide an overview of relevant areas of application for AI in the education sector, with a focus on institutional education. Both the opportunities and risks are critically discussed and possible obstacles are examined in more detail. One of the most promising area of application for AI in education is the personalization of learning processes.
Learning paths, tasks and feedback mechanisms are individually tailored to the needs of learners. This paper attempts to identify the particular potential in this area. In the field of language learning, there are already a number of educational programs that use the support of AI. A specific case study is presented and analyzed from both a didactic and technological perspective. Finally, an outlook on possible developments in the field of AI in education is given to show possible perspectives and scenarios for the future
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
