The professional knowledge of students at the technical school for civil engineering
No full textIm Beitrag werden Schüler*innen (N = 503) der nur wenig erforschten postsekundären Berufsbildung fokussiert. Die längsschnittlich angelegte Untersuchung mit drei Messzeitpunkten liefert eine anschlussfähige Skalierung und Strukturmodellierung des berufsfachlichen Wissens zu Beginn, während und zum Ende der fachschulischen Weiterbildung von Lernenden an bautechnischen Fachschulen der Fachrichtung Hochbau in den Bundesländern Baden-Württemberg, Bayern und Hessen. Hierfür wurden paper-pencil basierte Testinstrumente entwickelt, pilotiert und eingesetzt. Die Auswertung der Daten erfolgte mittels multivariaten statistischen und IRT-basierten Methoden. Die Untersuchung liefert ein empirisches Beschreibungs- und Erklärungswissen zum berufsfachlichen Wissen von Lernenden an Fachschulen. Das Fachwissen lässt sich in der Grund- und Fachstufe jeweils dreidimensional modellieren. Es werden Zusammenhänge und auf das Fachwissen relevante Einflussfaktoren sowie bundeslandübergreifende- und vergleichende Analysen präsentiert, diskutiert und Limitationen angesprochen.The article focuses on students (N = 503) of the only little-researched post-secondary continuing training. The longitudinal study with three measuring points provides a connectable scaling and structural modeling of the professional knowledge at the beginning, during and at the end of the further education of students at technical schools for civil engineering in the federal states of Baden-Württemberg, Bavaria and Hesse. For this purpose paper-pencil based test instruments were developed, piloted and applied. The data was evaluated using multivariate statistical and IRT-based methods. The study provides an empirical description and explanation of the vocational knowledge of learners at technical schools. The specialized knowledge can be modeled three-dimensionally in the basic and specialized levels. Interrelationships and factors of influence relevant to specialist knowledge as well as interstate and comparative analyses are presented, discussed and limitations are addressed
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
Vorbildung, Studienmotivation und Gründe eines Studienabbruchs von Studierenden im Lehramt an berufsbildenden Schulen
Full text linkDie vorliegende Untersuchung liefert ein systematisch begründetes Beschreibungswissen zu (1.) den soziodemografischen Merkmalen, (2.) der beruflichen und akademischen Vorbildung, (3.) dem Erstkontakt und der Studienmotivation von Lehramtsstudierenden in den Fachrichtungen Bau-, Elektro-, Maschinenbautechnik und Informatik, die zu Beginn ihres Studiums mit quantitativen und qualitativen Methoden befragt wurden. Die Ergebnisse zeichnen ein vielschichtiges Bild zu den soziodemografischen und motivationalen Ausgangslagen der Lehramtsstudierenden. In einer weiteren qualitativen Studie mit Studierenden, die das berufsschulische Lehramtsstudium abgebrochen bzw. den Studiengang gewechselt haben, werden (4.) zentrale Gründe für einen Studienabbruch dargestellt.Schlüsselwörter: Lehramtsstudium, gewerblich-technisch, Studienabbruch, Studienmotivation, Vorbildung____________Educational background, motivation to study and reasons for a study discontinuation of teacher training students for vocational training schoolsThis study provides a methodical reasoned description knowledge for (1) the sociodemographic characteristics, (2) the professional and academic educational background, (3) the initial contact and motivation to study of teacher training students in the fields of construction engineering, electrical engineering, mechanical engineering and computer science, which have been surveyed with quantitative and qualitative methods at the beginning of their studies. The results present a many-layered picture of the sociodemographic and motivational starting positions of teacher training students. In a further qualitative study of students, which have discontinued their teacher training for vocational training schools or which have changed their course of study, (4) key reasons for the discontinuation of study are provided.Keywords: Teacher training, industrial-technical, discontinuation of study, motivation to study, educational backgroun
