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
Performa Performa Usaha Ternak Sapi Potong di Distrik Masni Kabupaten Manokwari: Business Performance of Beef Cattle in Masni District Manokwari Regency
No full textAbstract
This study aims to determine the business performance of beef cattle farmers in terms of livestock production and productivity and the income of farmers from beef cattle business. The research was conducted descriptively with survey techniques through interviews and field observations. Primary data was taken by conducting interviews with farmers or those who run beef cattle business, extension workers, and stakeholders in the field of animal husbandry. The observed variables included maintenance, housing, feeding, reproductive system and BCS as well as cattle farming business analysis. The data obtained were analyzed descriptively to determine the important values (means, maximum value, minimum value and standard deviation) and presented in tabular form. The t-test was carried out to determine conclusively the existence of the change phenomenon at the beginning of raising and now (late). The results of the study show that the performance of beef cattle business in Masni District has enormous potential as indicated by an efficient livestock production system, a high reproduction system and a profitable livestock business analysis value. The results of the t test show that there is a significant increase for the population and also the price with a B/C Ratio value was 1.9.

Penelitian bertujuan mengetahui performa usaha peternak sapi potong dari segi produksi dan hasil pendapatan peternak dari usaha sapi potong. Penelitian dilakukan secara deskriptif dengan teknik survei melalui wawancara dan observasi lapangan. Data primer diambil dengan melakukan wawancara terhadap peternak atau yang menjalankan usaha ternak sapi potong, penyuluh, dan stake holder dibidang peternakan. Varibabel yang diamati meliputi pemeliharaan, perkandangan, pemberian pakan, sitem reproduksi, BCS (Body Condition Score) serta analisis usaha peternakan sapi. Data yang diperoleh dianalisis secara deskriptif untuk mengetahui nilai-nilai penting (means, nilai maksimum, nilai minimum dan standar deviasi) serta disajikan dalam bentuk tabel. Uji t dilakuan untuk mengetahui secara meyakinkan keberadaan fenomena perubahan saat awal beternak dan saat ini (akhir). Hasil penelitian menunjukkan bahwa performa usaha ternak sapi potong di Distrik Masni Kab. Manokwari memiliki potensi yang sangat besar. Hal ini ditunjukkan oleh sistem produksi ternak yang efisien, indeks reproduksi yang tinggi dan nilai analisa usaha ternak yang menguntungkan. Hasil Uji t menunjukkan bahwa ada peningkatan yang signifikan untuk populasi dan harga dengan nilai B/C Ratio adalah 1.9.

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
Pengaruh Tepung Cangkang Rajungan (Portunus pelagicus) sebagai Sumber Kitin dalam Ransum terhadap Kandungan Lemak Feses dan Efisiensi Pakan Tikus Putih (Rattus norvegiccus) Strain Wistar (The Effect of Crabs Shells (Portunus pelagicus) as A Source of Chi
Full text linkCangkang rajungan mengandung kitin yang persentasenya paling besar berupa polisakarida. Kitin dan derivat-derivatnya telah banyak digunakan dalam berbagai keperluan terutama untuk kesehatan. Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh pemberian tepung rajungan sebagai sumber kitin terhadap efisiensi pakan dan kandungan lemak feces tikus putih Rattus norvegicus) strain Wistar. Penelitian menggunakan rancangan acak lengkap pola faktorial 2x5 dengan tiga kali ulangan. Faktor pertama adalah jenis kelamin dan kedua level tepung rajungan yaitu 0%, 5%, 10%, 15%, and 20%. Hasilnya penelitian menunjukkan tidak ada interaksi antara jenis kelamin dengan kandungan teung rajungan dalam ransum. Kandungan lemak dalam feces tertinggi diperoleh dari perlakuan 10% yaitu 0.737%. Sedangkan efisiensi pakan tertinggi diperoleh dari penggunaan tepung rajungan 5% yaitu 13.1%. Penggunaan tepung rajungan dalam ransum mampu mningkatkan efisiensi pakan dan menurunkan kadar lemak tubuh tikus putih.Kata Kunci : Tepung rajungan, efisiensi pakan, lemak feces, tikus putih
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
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
