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

FACTORS PREDICTING MATHEMATICS TEACHERS’ USE OF LAPTOPS
Get PDFICT improves the way mathematics is being taught and enhances student understanding of basic concepts. Many researchers have carried out studies to evaluate the benefits of using ICT in mathematics. Laptop is one of the ICTs being used and adopted for the delivery of mathematics instructions. In Nigeria, the use of laptop for mathematics instructional delivery at the secondary school level has just begun to gain pace. In the light of this, it is considered necessary to examine factors predicting use and adoption of laptops by the secondary school mathematics teachers. In the light of this, this paper examines factors predicting mathematics teachers’ use of laptop. The population of the study comprised 600 secondary school’s mathematics teachers who were selected from secondary school across South West geo-political zone in Nigeria. A survey approach was adopted for the study and questionnaire was used for the collection of data on the study. The study reveals that, six factors except computer anxiety correlate with mathematics teachers’ use of laptops. The six factors (ease of use, perceived usefulness, prior computer experience, teaching quality, and teaching effectiveness and Computer anxiety) together made 74% of mathematics teacher laptops use. The entire actors again exerted significant contribution to mathematics teachers’ uses of laptops. In other words, the six laptops use prediction variables significantly explain use of laptops by the mathematics teachers. Since the study demonstrated that laptops is easier to use and its considered being useful and improve the quality of teaching and makes teaching effective; it is recommended that mathematics teachers who have phobia for the use of laptops should do away with the phobia, and endeavour to familiarise themselves with the laptop so that they can as well make use of it to improve their teaching and instructional delivery of the subject

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
