A study on the perceptions and efficacy towards inclusive practices of teacher trainees
Questo lavoro presenta uno studio sulle dimensioni implicite che influenzano l’agire didattico finalizzato ad indagare i sentimenti, gli atteggiamenti, le preoccupazioni, e i livelli di percezione dei docenti circa la propria efficacia nell'implementare pratiche inclusive. Il campione è stato suddiviso in due gruppi, il primo comprendente 221 corsisti del Tirocinio Formativo Attivo e il secondo costituito da 131 partecipanti al corso di specializzazione per insegnanti di sostegno.
Per condurre l’indagine sono state somministrate due scale: la scala TEIP e la scala SACIE-R. I risultati hanno mostrato che i futuri insegnanti di sostegno del campione raggiungono generalmente punteggi più alti. Tuttavia, sembrerebbe che l’atteggiamento positivo di questi docenti non risulti essere legato alla loro esperienza di insegnamento,
bensì alle caratteristiche dei percorsi della loro formazione.This paper presents a study on the implicit dimensions that influence teacher agency and is aimed at investigating the teachers’ sentiments, attitudes, concerns and perceived levels
of efficacy to implement inclusive practices. The sample comprised two groups: the first included 221 pre-service teachers undergoing training to teach in secondary schools and the second were 131 in-service teachers following a course to obtain the learning support teachers’ warrant. The TEIP and the SACIE-R scales were administered to conduct the study. Results showed that the future learning support teachers had generally higher scores than the pre-service teachers. The positive attitude of the former group towards inclusive
practices, however, seemed not to be linked to their greater teaching experience but more likely to the characteristics of their course of education
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
High-speed 5-axis machining for tooling applications
CITATION: Saxer, M., De Beer, N. & Dimitrov, D. M. 2012. High-speed 5-axis machining for tooling applications. South African Journal of Industrial Engineering, 23(3):144-153, doi:10.7166/23-3-517.The original publication is available at http://sajie.journals.ac.zaENGLISH ABSTRACT: In the modern metalworking industry, production moulds often have complex geometry, with undercut regions, small corner radii, sharp edges, deep cavities, or large cores. Conventional manufacturing process chains to machine these complex features are often lengthy and inefficient due to multiple steps. This article presents current results obtained through industry projects and experimental work using 5-axis high-speed machining with high-end CAD/CAM systems to improve process efficiency. Cost optimisation and lead time shortening can be clearly shown. This is of particular importance for South African manufacturing companies, where multi-axis HSC technology although not totally unknown is significantly under-used.AFRIKAANSE OPSOMMING: In die moderne metaalnywerheid word produksiegietvorms dikwels gekenmerk deur komplekse geometrië, bv. ondersny areas, klein hoek radiusse, skerp rante, diep holtes, en groot kerne. Konvensionele vervaardigingsproseskettings om hierdie komplekse kenmerke te masjieneer is dikwels langdurig en ondoeltreffend weens veelvuldige stappe. Hierdie artikel dui op resultate verkry vanaf industrie-verwante projekte, sowel as eksperimentele werk, waar ’n 5-as hoë spoed freesmasjien gebruik was tesame met top reeks CAD/CAM stelsels om prosesdoeltreffendheid te verbeter. Koste optimisering en verkorting van lei tye kan duidelik getoon word, wat van besondere belang is vir Suid-Afrikaanse vervaar-digingsmaatskappye wat van multi-as hoë spoed masjieneringstegnologië gebruik maak.http://sajie.journals.ac.za/pub/article/view/517Publisher's versio
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
