Construction and validation of the TESL foundation entrance test in a public university / Geethanjali Narayanan
Get PDFIn the 2015 Global Monitoring Report, there is a large disparity in the pupil-teacher ratios across the globe. However, to address this issue, the quality of the recruitment of teachers should not be brushed off. Teachers must be well versed in their subject matter to make them authoritative and credible. The development of a highly qualified and committed teaching force is one of the main concerns of the global educational reform. As such the aim of this study was to construct and validate an English Language entrance test (ATET) for the TESL foundation programme in a public university, so that the graduating students from this programme will be highly sought after at the TESL degree level, making them more knowledgeable and authoritative in their field. The ATET was developed and validated over 4 years, 2010-2013, to determine the items have psychometric properties. The construction and validation of ATET employed the framework that maps the Rasch Model and Kane‟s Validity Argument. Winsteps was used to analyse the bulk of the quantitative data which showed fit and order validity. The final outcome, after three sequentially improvised versions, was ATETv3 with 60 MCQ items, testing Reading, Grammar and Writing skills and one essay question (open-ended). These items range in difficulty between -3.24 and 4.38 logits, with Person Reliability of 0.86 and Item Reliability of 0.98 and Cronbach Alpha, 0.8. The essay component was analysed using Facets as well as EduG and the D-Study (Decision Study) suggested one rater (an experienced one) is sufficient, with a G-coefficient of 0.91. Meanwhile this study also established Predictive (r=0.85) and Construct (r=0.78) validity using SPSS. On the whole the cut-off point to be accepted into the programme was set at -1 logit. The paper-pencil ATET, which was originally meant to select appropriate candidates for the TESL foundation programme, is currently adopted as a digitized diagnostic test, conducted online in a public university
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
Myoelectric control of prosthetic hands: state-of-the-art review
No full textPurushothaman Geethanjali School of Electrical Engineering Department of Control and Automation VIT University, Vellore, Tamil Nadu, India Abstract: Myoelectric signals (MES) have been used in various applications, in particular, for identification of user intention to potentially control assistive devices for amputees, orthotic devices, and exoskeleton in order to augment capability of the user. MES are also used to estimate force and, hence, torque to actuate the assistive device. The application of MES is not limited to assistive devices, and they also find potential applications in teleoperation of robots, haptic devices, virtual reality, and so on. The myoelectric control-based prosthetic hand aids to restore activities of daily living of amputees in order to improve the self-esteem of the user. All myoelectric control-based prosthetic hands may not have similar operations and exhibit variation in sensing input, deciphering the signals, and actuating prosthetic hand. Researchers are focusing on improving the functionality of prosthetic hand in order to suit the user requirement with the different operating features. The myoelectric control differs in operation to accommodate various external factors. This article reviews the state of the art of myoelectric prosthetic hand, giving description of each control strategy.

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
