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
Pertumbuhan Dan Produksi Senyawa Antimikroba Dari Lactobacillus Plantarum Iia-1a5 Pada Media Whey Keju
No full textLactobacillus plantarum IIA-1A5 sebagai isolat indegenus dari daging sapi di Indonesia mempunyai kemampuan untuk menghambat bakteri patogen. Tujuan dari penelitian ini adalah untuk mengetahui potensi whey keju untuk dijadikan sebagai media pertumbuhan L. plantarum IIA-1A5 dan produksi bakteriosin. Kurva pertumbuhan L. plantarum IIA-1A5 menghasilkan senyawa antimikroba pada fase logaritmik pada waktu inkubasi jam ke 28 dan 32. Purifikasi plantarisin IIA-1A5 menghasilkan peptida dengan ukuran berat molekul pada perlakuan whey 9.59 kDa dan whey+ (sukrosa,tripton,dan yeast extract) 9.59 kDa, berada pada kelas IIa (<10 kDa) terdiri dari peptida termostabil. Konsentrasi protein plantarisin yang dihasilkan L. plantarum IIA-1A5 pada perlakuan whey+ adalah 1883.17 mg/mL lebih tinggi dari perlakuan whey 325.58 mg.mL-. Berdasarkan uji aktivitas antimikroba plantarisin IIA-1A5 menunjukkan kemampuan aktivitas antimikroba terhadap S. aureus ATCC 25923 dan E. coli ATCC 25922 bisa menghambat. Berdasarkan efektivitas plantarisin IIA-1A5 dengan uji aktivitas antimikroba whey sangat berpotensi untuk dijadikan media pertumbuhan untuk BAL

EVALUASI KEBERHASILAN INSEMINASI BUATAN PADA SAPI POTONG DI KECAMATAN PAMMANA KABUPATEN WAJO
Full text linkArtificial insemination (AI) has served as appropriate technology for ameliorating quality and population of cattle using superior male. Our present work aimed to evaluate AI service in District of Pammana, located in Regency of Wajo. Field survey and interview with inseminators were carried out to collect primary data, while secondary data was obtained from local government authority, i.e. department of food security and animal husbandry. The research investigated 320 acceptors during January – December 2020. Collected data was then descriptively analysed, while other parameters, i.e. service per conception (S/C) and conception rate (CR), were also assessed to evaluate AI efficiency. As the results, AI service in Pammana has been properly performed, as indicated by number of acceptors within 12 months. The inseminated acceptors in Pammana reached S/C score of 1.78 and CR of 60.37%, in which both indicators are rated as good. Male calf being born following AI was was more dominant (321) in comparison with female calf (283), with total calves born reaching 604

mean score of the pre-test was 61,08 and the post-test score was 80,00. Based
on the results of the independent sample t-test, the significant value (2-tailed)
0.00 was less than 0.05 when equal variances were assumed. The result of the findings showed that alternative hypothesis meaning that there was a significant effect of applying YouTube video in improving listening skill was accepted

Full text linkPenelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung daun pepaya (Carica papaya L.) pada pakan terhadap profil organ pencernaan ayam buras. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) 5 perlakuan 3 ulangan. Perlakuan terdiri dari P0 (control tapa perlakuan); P1 (pakan komersil + 2% tepung daun papaya); P2 (pakan komersil + 4% tepung daun papaya) P3 (Pakan komersil + 6% tepung daun papaya) P4 (pakan komersil + 8% tepung daun papaya). Parameter yang diamati profil organ pencernaan ayam buras. Semua data yang diperoleh dianalisis menggunakan analisis varian dari RAL dan dilanjutkan dengan uji Duncan jika hasilnya signifikan. Hasil penelitian menunjukkan bahwa penambahan tepung daun pepaya pada pakan ayam buras tidak pengaruh yang nyata (P>0,05) terhadap persentase berat dan panjang organ pencernaan ayam buras yang meliputi tembolok, proventrikulus, ventrikulus, usus halus, duodenum, jejenum, ileum, sekum, usus besar, pankreas.
