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
Explicit and Implicit Instruction of Discourse Markers to Heritage Speakers of Spanish
No full textThe controversy of using Explicit and Implicit Instruction is widely discussed in the field of Second Language Acquisition (SLA). SLA research generally addresses more salient linguistic elements, than less noticeable ones, e.g. Discourse Markers (DMs). Although Heritage Speakers (HS) learn the heritage language from a natural environment, research has found that HS may also benefit from formal instruction. The purpose of this pilot study is to determine whether Explicit or Implicit Instruction enhances the retention and production of DMs by HS of Spanish. Six HS of Spanish were exposed to two different types of instruction (Explicit-Implicit) on DMs and tested on accuracy and retention of DMs through an Oral Interview and a Forced Choice Task. Preliminary results on a small sample of HS suggest that Explicit Instruction may be beneficial for HS. However, this pilot study is worth replicating with a larger HS sample
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
The Effects of Explicit Pronunciation Instruction in Elementary Spanish: Perception and Production of Vowels
Full text linkResearch in pronunciation teaching in Spanish has focused mostly on intermediate or advanced levels, with only cursory attention paid to the elementary level. This research attempts to change that. Pronunciation is obviously an important aspect of second language learning, so teaching it at the elementary level could be assumed to be beneficial. The present thesis attempted to prove that hypothesis.
Thirty students completed the steps of the study, which involved tests of perception and production of Spanish words with a focus on vowels and word stress. The results showed that the experimental group’s perception improved significantly, while the control group’s perception declined over time despite continuing to take Spanish classes. The experimental group’s production also improved, though significance was conflictive in this study.
The results serve to amplify the research done in the area of second language pedagogy and ultimately help to determine whether pronunciation should be taught at the elementary level in Spanish
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
The Effects of Animation and Cueing in the Acquisition of Spanish Vocabulary
Full text linkAccording to Paivio’s (1971, 2007) Dual Coding Theory (DCT), cognitive information is stored in two separate systems, the visual and the verbal system. Both are linked through cognitive connections that lead to better memorization and remembering of both words and images. The current thesis intends to study the use of dynamic and static images in Spanish L2 vocabulary acquisition and the effects of cueing when presented with those two types of visual representations. An experiment was conducted in twenty-two sections of beginner Spanish at Auburn University in four days. Two conditions were applied, i.e. dynamic versus static images and cueing versus absence of cueing. The twenty-two sections were divided in four treatment groups: static and
absence of cueing (Control group), static and cueing (Group A), dynamic and absence of cueing (Group B), and dynamic and cueing (Group C). In order to gather data, participants were provided a recall and a recognition test both in a short term (after instruction) and a long term period (thirty-six days after instruction). Also, recall was divided in two different analyses: effectiveness (i.e. when the words were correct or orthographically related to the original) and production (i.e. only exact words were considered right). Results showed that there are no significant differences in the use of dynamic and static images in four of the six tests. However, dynamic images proved to be more effective in the short term recall test when measuring production. On the contrary, static images proved to be significantly better than static images in the long term recall test when measuring production. Discussion on the findings is presented
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
