Enhancing e-learning in old age
Get PDFThis study assesses the efficacy of e-learning content that has been adapted
to cognitive styles in a sample of older adults. Since the personalisation of
learning content has been generally associated with learning processes,
it was hypothesised that intrinsic motivation, metacognition and selfregulated
learning and learning strategies would interact in affecting
learning outcomes. A sample of 106 older adults attending the University
of the Third Age was divided into two groups on the basis of the learning
approach (face-to-face vs. online). Participants were asked to fill out
questionnaires that assessed cognitive styles, learning processes and
learning outcomes. A factorial ANOVA and path analysis were used.
Findings confirmed the efficacy of adapting e-learning content to older
adults’ cognitive styles, as well as the role played by intrinsic motivation,
metacognition and self-regulated learning, and learning strategies in
determining learning outcomes. Consequently, this research supports the
benefits of e-learning environments in facilitating learning processes and
in encouraging older adults to engage in learning activities
Luminance-free color detection for quantification and automatic segmentation in microscopy. A methodological approach.
Get PDFThis procedure is aimed at solving the chromatic quantification problem in histological images, as well as other fields. On digital images, this is possible using colorimetric software applications. Our solution was to adopt a pre-processing step of the analog signal coming from a video-source (cabling a suitable, dedicated unit to the video-line before signal grabbing). The unit is a hardware device that processes the voltage values of the video signal image section, line by line in the raster image exploiting the vertical interval. The output is a luminance-free video signal compatible with real-time needs (1/25 second), that is in turn compatible with the normal exploration speed of a histological slide. Some experimental results are presented
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
