No full textThe era of digitalization covers all aspects of everyday life without exception in the world of education. Learning to use media in the teaching and learning process requires teachers to be able and understand the use of learning media for smooth learning in the classroom. This type of research is qualitative with a descriptive approach using survey and interview methods. The research subjects were public elementary school teachers in the Bukit Raya sub-district, Pekanbaru City. Data analysis techniques using the SPSS 26.0 application. Based on the results of the research taken, it can be concluded that overall public elementary school teachers in the Bukit Raya Pekanbaru District are very good criteria for understanding learning media
KEANEKARAGAMAN EPILACHNINAE PADA BEBERAPA TANAMAN FAMILI SOLANACEAE DI KABUPATEN AGAM
Get PDFEpilachninae merupakan hama yang bersifat polifag dan tanaman inang utamanya adalah famili Solanaceae. Penelitian ini bertujuan untuk mempelajari keanekaragaman Epilachninae pada beberapa tanaman dari famili Solanaceae di Kabupaten Agam. Penelitian dilaksanakan di tiga kecamatan di Kabupaten Agam, yaitu Banuhampu, Canduang, dan Sungai Pua. Penelitian juga dilakukan di Laboratorium Bioekologi Serangga, Fakultas Pertanian, Universitas Andalas. Penelitian berlangsung mulai Maret sampai Mei 2017. Pengambilan sampel Epilachninae menggunakan metode mutlak, yaitu sampel diambil secara langsung dengan tangan pada Epilachninae yang ditemukan di dalam petak sampel. Hasil penelitian menunjukkan bahwa Epilachninae yang ditemukan pada beberapa tanaman Solanaceae di Kabupaten Agam sebanyak 13 spesies dan jumlah spesies tertinggi terdapat pada tanaman terung. Jika berdasarkan jenis tanaman maka indeks keanekaragaman Epilachninae tergolong rendah sampai sedang (0,47-2,01) Indeks keanekaragaman tertinggi terdapat pada tanaman terung. Indeks keanekaragaman berdasarkan lokasi penelitian tergolong rendah sampai sedang (0-2,00) dan tertinggi terdapat di Kecamatan Sungai Pua. Indeks kemerataan spesies berdasarkan jenis tanaman tergolong tinggi (0,68-0,80) dan tertinggi terdapat pada tanaman tomat. Berdasarkan lokasi penelitian indeks kemerataan tergolong rendah sampai tinggi (0-0,84) dan tertinggi terdapat di Kecamatan Canduang. Jenis tanaman berpengaruh terhadap indeks kesamaan spesies, sedangkan lokasi penelitian tidak berpengaruh terhadap indeks kesamaan spesies.

Profil Pemahaman Guru Tentang Media Pembelajaran di Sekolah Dasar
Get PDFPenelitian ini menyelidiki pentingnya pemahaman guru sekolah dasar terhadap media pembelajaran dalam konteks pendidikan modern. Pemahaman guru tentang media pembelajaran menjadi faktor kunci dalam meningkatkan efektivitas proses pembelajaran di tingkat dasar. Dalam era di mana teknologi dan media digital memegang peranan penting, guru yang mahir dalam penggunaan media pembelajaran dapat menciptakan lingkungan pembelajaran yang lebih menarik, interaktif, dan relevan bagi siswa. Penelitian yang digunakan adalah penelitian survey dengan menggunakan pendekatan kuantitatif. Penelitian ini dilakukan di Sekolah Dasar Negeri di Kecamatan Bukit Raya, Kota Pekanbaru, dengan melibatkan 23 guru sebagai responden. Hasil penelitian menunjukkan bahwa secara keseluruhan, mayoritas guru memiliki pemahaman yang baik hingga sangat baik tentang media pembelajaran. Namun, terdapat variasi dalam pemahaman guru terkait aspek-aspek khusus media pembelajaran seperti jenis-jenis media dan penggunaannya.Pemahaman guru tentang media pembelajaran bukan hanya tentang mengenal berbagai alat atau teknik media, tetapi juga tentang bagaimana mengintegrasikan media tersebut secara efektif ke dalam pembelajaran, mengkustomisasi penggunaannya sesuai dengan kebutuhan siswa, dan memaksimalkan potensi media tersebut untuk meningkatkan efektivitas proses pembelajaran.
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
