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
KEANEKARAGAMAN MAKROZOOBENTHOS SEBAGAI BIOINDIKATOR KUALITAS AIR DI DANAU SIPIN KOTA JAMBI
Full text linkPenelitian ini bertujuan untuk mempelajari spesies penyusun makrozoobenthos, tingkat keanekaragaman jenis, dan mengetahui kualitas air di Danau Sipin Kota Jambi. Metode yang digunakan adalah metode survei dengan penempatan stasiun dilakukan secara “Purposive Random Samplingâ€. Hasil penelitian didapatkan bahwa tidak ditemukan kehadiran spesies makrozoobenthos di stasiun pengamatan yang diartikan hasilnya adalah 0 (nol). Dengan analisis lebih lanjut bahwa indeks keanekaragaman jenis makrozoobenthos adalah 0 (nol) yang memiliki arti bahwa H’ < 1 maka keanekaragaman jenis tergolong rendah, produktivitas sangat rendah sebagai indikasi adanya tekanan yang berat dan ekosistem yang tidak stabil. Indeks Keseragaman (E) memiliki hasil nilai 0<E≤0,5 maka komunitas tertekan keseragaman rendah. Kesimpulan dari penelitian ini adalah kehadiran yang nihil menunjukkan bahwa keanekaragaman rendah, produktivitas sangat rendah sebagai indikasi adanya tekanan yang berat dan ekosistem tidak stabil. Akibat dari komunitas yang tertekan menyebabkan keseragaman rendah dan dominansi rendah. Berdasarkan hasil indeks keanekaragaman makrozoobenthos yang < 1,0 dan faktor lingkungan maka diindikasikan bahwa kualitas air Danau Sipin Kota Jambi dalam standar klasifikasi tingkat pencemaran tergolong berat/tinggi yang hanya layak dimanfaatkan sebagai penyedia air untuk pertamanan, atau usaha perkotaan atau usaha lain yang sesuai dengan persyaratan mutu air golongan IV
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
Pengembangan Media Pembelajaran Fisika berbasis Adobe Flash Professional CS6 Untuk Mata Kuliah Fisika Dasar I
Full text linkThe aim of this research is to develop learning media based on adobe flash professional CS6 on the subject of mechanics (kinematics and dynamics). In this research produced a product in which several questionnaires were distributed to several experts: media experts, concept experts, linguists, lecturers and students, to find out the validity, practicality and effectiveness of learning media. The research method uses the ADDIE approach (Analysis, Design, Development, Implementation, Evaluation). The results of this study found that the learning media has good indicators. This is evidenced by the results of data analysis obtained from respondents. Based on the assessment of media experts, concept experts and language experts learning media are categorized as very valid, with an average percentage of 91.25% by media experts, 92% by concept experts and 100% by language experts. The practicality of the media obtained 91% of the responses of lecturers, 84% of students with very practical criteria. The effectiveness of the media obtained from an increase in student learning outcomes by 0.8% with high improvement criteria. From the results of the data obtained, this learning media have valid criteria according to experts, practical, and effective and can be used by lecturers and student
