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
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
Simulasi dan Disain Mesin Penanam Kentang
Full text linkIn line with regional development programs of horticulture, potato is a strategic commodity to support food security. However, recently, the difficulty and high cost of labor in the cultivation of potatoes became a constraint in supporting the government's program. Therefore, it is needed a breakthrough by using appropriate mechanization technology. Bythis effort, the difficulties of farmers may soon be resolved by introducing this technology, ICAERD has been conducted design and development of potato planter. This planter has a fairly high difficulty because the seed of potatoes have certain characteristics that are easily damage if it is not handled properly and has relatively non-uniform tubers. Therefore, designof potato planter was begun with a simulator to test in the laboratory related to the design of metering device, hopper and rotation of metering device associated with plant spacing. In planning, the design was also considered a variety of factors such as factors that is affected by the land condition, user target and level of technology. Test performance refers to standard testing procedures for potato planter generated by hand tractor (walking type).Field test of potato planter generated by hand tractor with a power of 6.34 kW (8.5 HP) and a weight of 200 kg, the operation speed of 1.7 km / hour with one row planting and working capacity was 8 hours / ha, slip was 6.3% and the working efficiency was 75%.Keywords: simulation, design, performance test, walking type, potato plante

No full textLirnbah industri pertanian (rninyak kelapa sawit, tapioka, pabrik gula, peternakan sapi) dapat dirnanfaatkan untuk energi biogas dengan cara ferrnentasi anaerob. Proses ini rnelibatkan bakteri rnethanogen untuk rnerornbak bahan-bahan organik yang terkandung didalarn lirnban rnenjadi biogas dan lurnpur sisa ferrnentasi yang dapat dirnanfaatkan rnenjadi pupuk. Kegiatan dengan konsep nir lirnbah (zero waste) seperti ini lebih rarnah lingkungan dan berkelanjutan. Balai Besar Pengernbangan Mekanisasi Pertanian telah rnengernbangkan reaktor biogas kapasitas 78 rn3atau dapat rnenarnpung kotoran sapi sebanyak 10-12 kkor. Reaktor biogas rnarnpu rnengahasilkan biogas sebanyak 6 rn3/ hari. Hasil pengarnatan suhu reaktor biogas berkisar 2527°C dan pH 7-7,8 rnenghasilkan biogas dengan kandungan gas rnetana (CHJ sekitar 77%. Biogas yang dihasilkan dirnanfaatkan sebagai surnber energi pada kornpor gas, larnpu penerangan dan generator listrik skala rurnah tangga. Analisa darnpak lingkungan dari lurnpur keluaran dari reaktor biogas rnenunjukkan penurunan COD dan BOD berturut-turut sebesar 90% dan 40% dari kondisi bahan awal. Analisa unsur utama N. P dan K rnenunjukkan tidak ada perbedaan nyata bila dibandingkan dengan pupuk kornpos referensi. Analisa kelayakan ekonorni rnenunjukkan investasi layak dengan BIC Rasio 1,35 dan modal investasi kernbali pada tahun ke-4 (urnur ekonomi reaktor biogas 20 tahun). Uji kinerja motor bakar diesel dengan bahan bakar solar-biogas untuk rnernbangkitkan daya listrik 3000 Watt rnenunjukkan hasil yang rnernuaskan, dengan konsurnsi bahan bakar solar 100 rnlfjarn dan 0.39 rn3 biogas/kwh. Motor bakar ini sangat rarnah lingkungan karena ernisi gas buang sangat kecil dibandingkan SNI dan tingkat kebisingan 85 dB. Dan secara ekonorni layak dengan BC ratio 2,17; IRR=44,96 dan Simple Payback=1,3 tahun. Hasil pendapatan ini belurn terrnasuk hasil sarnping berupa pupdk cairlpadat. Berdasarkan kajian teknis dan ekonornis tersebut, teknologi biogas ini layak dikembangkan dan diaplikasikan dengan skala yang lebih besar untuk rnenangani lirnbah industri pertanian
