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
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
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
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
CORRELATION BETWEEN SELF-REGULATED LEARNING AND ACADEMIC ACHIEVEMENT OF CHEMISTRY EDUCATION STUDENTS OF FKIP SRIWIJAYA UNIVERSITY
Full text linkThe objectives of this research are to identify the self-regulated learning, academicachivement, the mostly used aspects of self-regulated learning, and the correlactionbetween the self-regulated learning and academic achievement of chemistry educationstudents of FKIP Unsri. This research is acorrelational study. The sample of thisresearch is the 72 students of chemistry education chosen randomly. The data weregathered by using questionnaire and documentation. The results of this research showedthat the chemistry education students had high self-regulated learning, highly satisfiedGPA and mostly used 5 out of 7 aspects of self-regulated learning. The statisticalanalysis showed that there was no significant correlation between self-regulatedlearning and academic achievement of chemistry education students. However, one outof the 7 aspects of self-regulated learning—evaluting the effectiveness--correlatedsignificantly to the students’ academic achievement
PENGARUH PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE STUDENT TEAMS ACHIEVEMENT DIVISIONS (STAD) TERHADAP HASIL BELAJAR KIMIA MATERI STOIKIOMETRI SISWA KELAS X MIPA DI SMA NEGERI 3 TANJUNG RAJA
Full text linkAbstrak: Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif tipe Student Teams Achievement Divisions (STAD) terhadap hasil belajar siswa kelas X SMA Negeri 3 Tanjung Raja pada materi stoikiometri. Penelitian ini merupakan penelitian eksperimen semu dengan rancangan penelitian Nonequivalent Control Group Design. Adapun sampel penelitian adalah siswa kelas X yang terdiri dari kelas X-1sebagai kelas eksperimen dan kelas X-2 sebagai kelas kontrol. Uji hipotesis penelitian ini menggunakan uji independent sample t-test. Berdasarkan hasil uji hipotesis diperoleh nilai signifikansi sebesar 0.000, sehingga dapat disimpulkan sig 2-tailed < 0,05. Hasil tersebut menyatakan bahwa Ho ditolak dan Ha diterima. Sehingga dapat disimpulkan bahwa ada pengaruh yang signifikan pada penerapan model pembelajaran kooperatif tipe Student Teams Achievement Divisions terhadap hasil belajar kimia materi stoikiometri.Kata Kunci: model pembelajaran kooperatif tipe STAD, dan hasil belajar. Abstract: This research aims to knowing the influence of cooperative learning type Student Teams Achievement Divisions (STAD) in learning outcomes ten grade students of senior high school 3 Tanjung Raja on the stoichiometry material. This research was a quasi-experimental research with the research design was Nonequivalent Control Group Design. And research sample is X class student which is consist of X-1 as experiment class and X-2 as control class.The test of hypotheses using independent sample t-test. Out based on the results of hypothesis testing obtained a significance value of 0.000, So it can be concluded sig 2-tailed< 0.05. These results state that Ho is rejected and Ha is accepted. So that there is a significant effect on the application of cooperative learning model Student Teams Achievement Divisions type toward chemical learning outcomes stoichiometry material. Keywords: cooperative learning model of STAD type, and learning outcomes.
