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
Pengaruh Level Protein dan Level Lisin Ransum terhadap Pemanfaatan Energi untuk Pertumbuhan pada Ayam Kampung Umur 12 Minggu

ERZA SYABRINA. 23010110110020. 2014. Pengaruh Level Protein dan Level
Lisin Ransum terhadap Pemanfaatan Energi untuk Pertumbuhan pada Ayam
Kampung Umur 12 Minggu (The Effect Level of Protein and Level of Lysine Diet
to Metabolizable Energy for Growth on Native Chicken 12 Week). (Pembimbing :
UMIYATI ATMOMARSONO dan HANNY INDRAT WAHYUNI)
Daging ayam kampung lebih disukai konsumen karena rasanya dan juga
lebih rendah lemak dibandingkan dengan ayam non lokal. Ayam kampung
memiliki kekurangan yaitu laju pertumbuhannya lambat. Salah satu cara untuk
meningkatkan produktivitas ayam kampung dilakukan dengan memperhatikan
kandungan nutrisi ransumnya. Nutrisi yang mempengaruhi pertumbuhan dan
produktivitas ayam kampung diantaranya adalah protein. Sumber protein ransum
yang baik adalah yang mengandung asam amino sesuai dengan kebutuhan tubuh
terutama asam amino esensial yang tidak dapat disintesis oleh tubuh ayam. Salah
satu asam amino esensial yang jumlahnya kurang di dalam ransum adalah lisin.
Penelitian ini bertujuan mengetahui pengaruh level protein dan level lisin
dalam ransum terhadap pemanfaatan energi metabolisme (EM), untuk
meningkatkan pertumbuhan ayam kampung, dengan mengamati nilai aktivitas
fosfatase alkalis (AFA) dan bobot badan. Penelitian dan analisis energy masingmasing
dilaksanakan di Kandang Laboratorium Produksi Ternak Unggas dan
Laboratorium Ilmu Nutrisi dan Pakan Fakultas Peternakan dan Pertanian
Universitas Diponegoro sedangkan analisis darah di Balai Laboratorium
Kesehatan Jawa Tengah.
Materi yang digunakan adalah 240 ekor Day Old Chick (DOC) ayam
kampung unsex. Kandang pemeliharaan terdiri dari 24 unit, bertipe koloni diisi
masing-masing 10 ekor ayam. Ransum percobaan terdiri atas jagung, bekatul,
tepung ikan, bungkil kedelai, minyak nabati, CaCO3, L-lisin HCl, DL-metionin
dan premiks. Rancangan yang digunakan rancangan acak lengkap (RAL) pola
faktorial (2 x 3) dan 4 ulangan. Faktor pertama yaitu level protein, masingmasing
17 dan 14% sedangkan faktor kedua adalah level penambahan lisin L1, L2
dan L3 masing-masing sebesar 0,6; 0,7 dan 0,8%, dengan kandungan EM ransum
sama 2.800 kkal/kg. Parameter yang diamati meliputi EM, AFA dan bobot badan.
Data dianalisis dengan analisis ragam dan jika terdapat pengaruh yang nyata maka
dilanjutkan dengan uji Duncan.
Hasil penelitian menunjukkan tidak ada interaksi dari pengaruh perlakuan
level protein dan level lisin dalam ransum terhadap semua parameter yang diukur.
Rerata EM ransum perlakuan pada ayam kampung dengan kombinasi perlakuan
P1L1, P1L2, P1L3, P2L1,P2L2 dan P2L3 masing-masing sebesar 2.957,3;
2.836,9; 2.692,9; 3.068,5; 3.020,4 dan 2.998,2 kkal/kg, sementara rerata AFA
masing-masing adalah 3.918,50; 2.940,50; 5.085,75; 1.984,50; 3.175,25 dan 2.231,50
vi
U/l, dan rerata bobot badan berturut-turut yaitu 551,14; 500,03; 573,64; 554,63;
530,42 dan 546,17 g.
Kesimpulan yang diperoleh bahwa level protein 14-17% dan level lisin 1,1-
1,6% pada ransum ayam kampung yang diberikan sampai umur 12 minggu belum
dapat meningkatkan bobot badan yang ditunjukkan dengan nilai EM dan AFA
yang sama
