KONSEPSI SISWA TENTANG MATERI BANGUN RUANG SISI DATAR DITINJAU DARI GAYA KOGNITIF SISWA KELAS VIII SMP NEGERI 2 BAYAN KABUPATEN LOMBOK UTARA TAHUN AJARAN 2014/2015
Get PDFThe objectives of research were: (1) to describe the conception of the 8th graders of SMP Negeri 2 Bayan with field independent (FI) cognitive style on definition and elements of cube and beam, (2) to describe the conception of the 8th graders of SMP Negeri 2 Bayan with field dependent (FD) cognitive style on definition and elements of cube and beam. This study was a qualitative research with case study approach. The subjects of research were selected using purposive sampling technique. The subjects of research was the even-semester 8th graders of SMP Negeri 2 Bayan in the school year of 2014/2015 consisting of 4 students with field dependent and 4 students with file independent cognitive styles. The instrument employed in collecting data was author, and supporting instruments were interview guidelines and interview guide. Technique of collecting data used was unstructured interview. Data validation was carried out using time triangulation. Techniques of analyzing data used were data reduction, data display and conclusion drawing. The result of research showed that: (1) the conceptions of the 8th graders of SMP Negeri 2 Bayan with field independent (FI) cognitive style on defining cube and beam and elements of cube and beam were a) defining cube as a structure with 6 square sides with volume: side times side times side (volume s3), while beam as flat side spatial structure made of rectangles, b) defining cube as a spatial structure consisting of 6 equal sides, 8 vertexs, and 12 edges, while, beam as a spatial structure consisting of square and rectangular sides, with 8 vertexs, and 12 edges, c) defining cube as a three-dimension structure, all sides of which are equal, while beam as spatial structure with unequal length, width and height. Regarding the elements of cube and beam, the students mentioned that cube and beam shared same elements: side, edge, vertex, side diagonal, and spatial diagonal. (2) The conceptions of the 8th graders of SMP Negeri 2 Bayan with field dependent (FD) cognitive style on defining cube and beam and elements of cube and beam were a) defining cube as a structure as a spatial structure with equal sides and beam as the one with unequal sides, b) defining cube as a spatial structure with 6 square sides while beam as the one made of square and rectangular sides, c) defining cube as a structure with equal sides, while beam as the one with length, width and height. Regarding the elements of cube and beam, the students mentioned that cube and beam shared same elements: side, vertex and edge. Keywords: Conception, cube, beam, field dependent and field independen
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
