The Effects of Odor on Vocabulary Learning
Get PDFExplicit vocabulary learning is a burden for most of the students. But vocabulary is the basis of each language, and not all words can be acquired incidentally through context or reading. Especially for content and language integrated learning in L2 it is important to offer lots of support for learning a large number of terms in order to avoid frustration and negative impact on motivation for the subject. This classroom study investigated the effects of odor on L2 vocabulary learning. The olfactory sense is connected with the limbic system and therefore associated with emotions and motivation. Young EFL Learners (n=158) were randomized to 7 different groups to compare the effects on retention of vocabulary, on motivation and concentration. A mix of essential oils that is proven to enhance concentration and vigilance was given as support. Major finding found as a result of the testing was the positive correlation with the time during a school day the odor was offered as support
Effects of Bilingual Biology Teaching at Middle Schools
Get PDFThis classroom-based study investigates the relative effectiveness of content and language integrated learning in Biology for students with limited knowledge of English. The sample comprised 252 German-speaking learners of English taking intermediate English courses (3rd year of English learning) at a special secondary school (German “Mittelschule), who were randomly assigned to one of three groups: lesson being conducted in English, the lesson being conducted in German, and a control group. A teaching unit about the topic “breathing” served as intervention. To determine the effects of the two instructional methods, the participants’ prior knowledge about the topic and their motivation based on general interest in the subject, specific interest in the topic and the level of self-efficacy experienced was measured beforehand with pre-tests. An immediate post-test about content knowledge and motivation was taken right after the lesson, a post-test after one month should show long term consolidation or change in motivation. Even though most other studies show negative effects of bilingual teaching for students with a low level of language skills, the results here indicate that neither knowledge nor motivation in classes with relatively little knowledge of English was significantly different in both groups, students with multilingual background seemed to even benefit from the bilingual instruction provided that specially prepared lessons were used serving the learning needs of the students
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
