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
Teachers’ utilization of instructional skills in the 21st century classroom
Get PDFIf education is the most powerful instrument for social and economic progress of any country, then teachers are the heart of any educational enterprises and the life of any school system. If teachers have the responsibility of translating educational policies into practice, then it is essential to assess the level to which teachers have the required skills to function effectively in the 21st century classroom. In view of this, the study evaluated the instructional skills of teachers in Southwestern Nigeria. It also assesses if there is significant difference in the skills of teachers based on teaching experience. The study adopted a survey research design using the CIPP model of evaluation. One hundred and five (105) teachers, in seven (7) local government areas, in the Southwestern part of Nigeria constitute the sample. An adapted and validated instruments was used for data collection and this is named “Teachers’ Instructional Skills Assessment Format” (r = 0.85). Data were analyzed using percentages and t- test and at 0.05 level of significance. The studies found that higher percentage of the participants have high instructional skills by recording 50% and above. The study found no significant difference in analytical, design, development, implementation and evaluation skills of experienced and less - experienced teachers. Although, there was no significant difference but the mean scores show that experienced teachers possessed better instructional skills. The study recommends that education stakeholders in Nigeria should rise up to improve the quality of teacher education programmes so that the newly inducted teachers would be able to face the challenges of 21st century classroom. Government should give priority to investment in human capital through teacher education and re-training of teacher educators. The study recommends that teachers’ skills development should be a continuous exercise so as to integrate pedagogical and technologies professionally in order to enhance learners’ performance.Keywords: Evaluation, Pedagogy, Teacher Education, SAI, Educational Technolog
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
Differences in Technological Pedagogical Content Knowledge Between Experienced and Less Experienced Computer Teachers in Ogun State, Nigeria
Get PDFThis study assessed differences in technological pedagogical content knowledge (TPACK) between experienced and less experienced computer studies teachers in Ogun State, Nigeria. Three research questions were used in the survey research, with a total number of two hundred (200) respondents, using multistage sampling technique. The instrument used was an adapted test scale measuring technological pedagogical knowledge (TPK), technological content knowledge (TCK) and technological pedagogical content knowledge (TPACK). It is divided into two sections with a reliability coefficient value of 0.78, 0.72 and 0.71 respectively, while data was analysed with t-test statistical method. The study revealed no significant difference in the technological pedagogical knowledge (TPK) between experienced and less experienced computer teachers (t = 0.346, P > 0.05), significant difference in the technological content knowledge (TCK) between experienced and less experienced computer teachers (t =2.423, P < 0.05) and significant difference in the technological pedagogical content knowledge (TPACK) between experienced and less experienced computer teachers (t =1.306, P < 0.05). In the recommendation, professional development in terms of continuous workshop, in-service training and seminar should be constantly organised for both experienced and less experienced secondary school computer teachers in Ogun State for improved TPK. Also, in-service training and seminar should be constantly provided for less experienced computer teachers in Ogun State for improved TCK and TPACK
Instructional Skills Possessed by In-Service Teachers in SouthWestern Nigeria
Get PDFParents, practitioners and policymakers agree that the key to improving public education in Nigeria is placing highly skilled teachers in all classrooms. However, studies reported that the challenges confronting Nigeria education system is attributed to some deficiencies in the structuring of teacher education, one of which is lack of needed instructional skills. It is in view of this that the study evaluated the instructional skills of in-service teachers in South West, Nigeria. The study further examined the extent to which teacher - factors such as teaching experience and academic qualifications influence possession of instructional skills.
The study adopted a survey research design. Five hundred and twenty five (525) teachers in seven (7) local government areas in the Southwestern Nigeria constituted the sample. An adapted and validated instrument “Teachers’ Instructional Skills Utilization Scale†(r = 0.74), was used for data collection. Data were analyzed using percentages, t- test and analysis of variance at 0.05 level of significance.
The study found that higher percentage of the participants possessed high instructional skills. The study found no significant difference in instructional skills possessed by experienced and less - experienced teachers. In terms of academic qualifications, there was no significant difference in analytical, design, development and evaluation skills possessed by the teachers. However, there was significant difference in the implementation skills among teachers with different teaching qualifications. (F (2, 522) = 3.408, p < 0.05).
Amongst others, it was recommended that Education Degree Programmes in Nigeria should emphisis acquisition of instructional skills for teaching effectiveness. It was also recommended that workshop and in-service training should be provided for the less experienced teachers because it was found that experienced teachers recorded higher mean scores in the skill areas.

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
