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
DESAIN MODEL REGRESI LINIER GANDA
Full text linkDalam dunia penelitian, metode statistika dengan regresi linear selain berguna sebagai metode untuk memberi cara guna menarik kesimpulan juga berguna untuk memilib persamaan regresi terbaik.
Dalam penulisan tugas akhir ini, akan dibahas cara mendesain model regresi linear ganda dan kegunaan teknik-teknik regresi linear ganda dalam membuat model regresi linear ganda yang variabel-variabel prediktornya saling berkorelasi. Dengan uji F Parsial dan beberapa teknik regresi linier ganda dapat dipilih beberapa variabel prediktor yang saling berkorelasi untuk dimasukkan ke dalam model, sehingga diperoleh suatu persamaan regresi terbaik.
Persamaan regre,si terbaik ini berisi
vaeiabel-variabel prediktor yang jumlahnya relatip kecil, tetapi masih cukup baik hanya untuk tujuan meramal respons, bukan untuk menilai pengaruh setiap variabel prediktor terhadap respons.

IDENTIFIKASI DAN DISTRIBUSI KEPADATAN LALAT PADA BEBERAPA MODEL PENGELOLAANSAMPAH DI TEMPAT PEMROSESAN AKHIR SAMPAH (TPAS) SUKOSARI KARANGANYAR
Full text linkSampah merupakan entropi dari aktivitas manusia. Meningkatnya populasi manusia secara langsung menjadikan pengelolaan sampah menjadi permasalahan global saat ini. Salah satu metode pengelolaan sampah adalah dengan melakukan sentralisasi pengelolaan pada lokasi khusus dan daur ulang. Penelitian ini mengkaji mengenai dampak sentralisasi pengelolaan sampah pada lokasi pengelolaan maupun lingkungan sekitar. Indikator yang diteliti adalah jenis dan jumlah lalat. Variasi pembanding berupa perbedaan model pengelolaan sampah dan waktu pengelolaan. Tujuan penelitian ini adalah untuk mengetahui : (1) jenis dan kemelimpahan lalat; (2) pengaruh model pengelolaan sampah terhadap populasi lalat; (3) pengaruh waktu sampling terhadap populasi lalat; dan (4) korelasi model pengelolaan sampah dan waktu sampling terhadap populasi lalat. Penelitian dilaksanakan di Tempat Pemrosesan Akhir Sampah (TPAS) Sukosari, Karanganyar pada bulan Maret hingga Juni 2015. Metode penelitian dilakukan dengan inventarisasi jenis dan jumlah lalat pada titik-titik model pengelolaan sampah berbeda di TPAS Sukosari dan satu titik di pemukiman sebagai kontrol dengan menggunakan peralatan fly grill ukuran standar. Model pengelolaan sampah di TPAS Sukosari dibagi menjadi tiga tipe yaitu : open dumping, open trench burning dan sanitary landfill. Pengambilan sampel tersebut dilakukan dalam variasi waktu pagi, siang dan sore. Analisis penelitian dengan menggunakan Univariate ANOVA untuk menentukan signifikansi pengaruh beda model pengelolaan dan waktu terhadap jumlah lalat serta Korelasi Pearson untuk mengetahui bentuk dan nilai korelasi antar variabel. Hasil penelitian ini mendapatkan 4 jenis lalat dalam inventarisasi di wilayah TPAS Sukosari yaitu Musca domestica (lalat rumah), Lucilia sericata (lalat hijau), Tabanus atratus (lalat pitak) dan Drosophila melanogaster (lalat buah). Lalat dominan pada kawasan TPAS Sukosari adalah Musca domestica. Frekwensi lalat tertinggi diperoleh di lokasi pengelolaan open dumping (mean 27,133) dan terendah di lokasi sanitary landfill (mean 3,667). Frekwensi lalat tertinggi berdasarkan waktu sampling didapatkan pada pagi hari (mean 24,450). Analisis ANOVA Univariate menunjukkan bahwa variasi model pengelolaan sampah, waktu sampling maupun keduanya secara bersamaan memberikan dampak signifikan pada jumlah lalat (sig 0,000). Pengaruh kedua variabel tersebut terhadap jumlah lalat tergolong tinggi (R2 : 0,982). Korelasi model pengelolaan sampah dan jumlah lalat adalah -0,575 (sig 0,000) menunjukkan korelasi negatif sedang. Sedangkan korelasi suhu dengan jumlah lalat adalah -0,408 (sig 0,001) menunjukkan korelasi negatif lemah. Penelitian ini menunjukkan bahwa model pengelolaan sampah sanitary landfill ideal untuk menjaga kualitas lingkungan dibuktikan dengan jumlah lalat ditemukan tidak berbeda signifikan dengan kontrol (sig 0,511)
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
