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
Laboratorium Virtual dengan Aplikasi PhET untuk Memperkuat Penguasaan Konsep Listrik Dinamis Siswa pada Pembelajaran Online
Full text linkOnline learning is the good solution to reduce the spread of the Covid-19 outbreak. Teachers can use PhET simulations to show students experiments during online learning. Some schools have limitations in implementing online learning, one of which is SMPN 3 Ampek Angkek. This is evidenced by the results of the student daily assessment (PH) which is still below the minimal mastery criteria. The purpose of this study was to analyze the progress of students' mastery of concepts on dynamic electricity in class IX of SMPN 3 Ampek Angkek. This research includes classroom action research. The subjects of this study were grade IX students of SMP Negeri 3 Ampek Angkek. The research instrument was a concept mastery test and a questionnaire. The results showed that there was an increase in the average concept mastery test in cycle 1 of 84.64 and cycle 2 of 91.86 with a minimal mastery criteria of 70. The data on student responses to the implementation of learning included both categories in cycle 1 and cycle 2. This study provides initial data as a basis for further researchers to design a student worksheet using a learning model that varies according to the level of difficulty of the learning material
Hubungan Peran Kader Posyandu Dengan Kelengkapan Imunisasi Dasar Di Wilayah Kerja Puskesmas Kota Kutacane
Full text linkBerdasarkan data imunisasi Puskesmas Kota Kutacane Aceh Tenggara, dengan jumlah sasaran bayi 337 jiwa, persentase bulan Januari-Desember Tahun 2019 persentase imunisasi Hepatitis B sebanyak 58%, persentase imunisasi BCG sebanyak 83%, persentase imunisasi DPT 1 sebanyak 81%, DPT 2 sebanyak 87%, DPT 3 sebanyak 78%, persentase imunisasi polio 1 sebanyak 94%, polio 2 sebanyak 100%, polio 3 sebanyak 95%, polio 4 sebanyak 90%, persentase imunisasi campak sebanyak 59%, dan bayi yang imunisasinya lengkap sebanyak 54%. Masih adanya imunisasi yang rendah cakupannya diduga karena kurangnya peran kader posyandu. Jenis penelitian ini adalah analitik dengan desain cross sectional. Penelitian dilakukan di wilayah kerja Puskesmas Kota Kutacane Aceh Tenggara. Populasi dalam penelitian ini sebanyak 306 orang dan sampel diperoleh sebanyak 75 orang. Data dianalisis secara analitik dengan menggunakan uji Chi-Square pada taraf signifikan 0,05. Hasil penelitian menunjukkan bahwa peran kader posyandu di Wilayah Kerja Puskesmas Kota Kutacane Aceh Tenggara menurut responden tidak aktif (50,7%). Kelengkapan imunisasi dasar bayi di Wilayah Kerja Puskesmas Kota Kutacane Aceh Tenggara dalam kategori tidak lengkap (56,0%). Peran kader posyandu berhubungan signifikan dengan kelengkapan imunisasi dasar di Wilayah Kerja Puskesmas Kota Kutacane Aceh Tenggara, p = 0 ,000 0,05.. Maka disarankan kepada petugas kesehatan di Wilayah Kerja Puskesmas Kota Kutacane Aceh Tenggara untuk memberikan penyuluhan dan informasi kesehatan kepada ibu tentang pentingnya melengkapi imunisasi dasar pada bayinya untuk mencegah dan menghindari penyakit yang dapat menular pada bayi
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
