VIABILITAS PUPUK HAYATI PENAMBAT NITROGEN (Azotobacter dan Azospirillum ) EKOSISTEM PADI SAWAH PADA BERBAGAI FORMULASI BAHAN PEMBAWA
Full text linkGenerally microbes in biofertilizer packaged in a carrier material powder and liquid form. Each inoculant requires media requirements and characteristics of differentcarrier materials. This research aims to study the composition of the carrier material N2 fixation biofertilizer (Azotobacter and Azospirillum) from paddy ecosystem in the form of powder. The study was conducted in two stages: (a) Test Viability of biofertilizer compositions from three carriers which performed at the Laboratory with the observed response variable bacterial populations on a regular basis ie 1, 2, 6, 10, 14, 18, 30 and, 42 weeks after production and (b) Testing the addition of nutrients and the ratio of pure cultures with the carrier materials on viability of bacteria using a complete randomized block design consisting of 12 treatment combinations of nutrients and the addition of pure cultures with different ratios of carrier. The experimental results show that the carrier material of peat and compost is the best carrier with the highest bacterial viability until the age of 42 weeks after the production of fertilizer. The formulation of biofertilizer with addition of 0.5% nutrient + 35% culture and biofertilizer formulation with the addition of 1% nutrient + 30% culture better in supporting the viability of the bacteria until the age of 20 weeks after production
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
Literature Review: Rekayasa Mikrobioma Rizosfer untuk Meningkatkan Kesehatan Tanah dan Produktivitas Tanaman Pangan dalam Mendukung Pertanian Berkelanjutan
Full text linkDampak dari intensifikasi pertanian tanpa memperhatikan kelestarian lahan pertanian sehingga lahan menjadi tidak produktif, padahal kebutuhan pangan semakin lama semakin meningkat. Artikel ini bertujuan untuk mengungkapkan kemampuan dari rekayasa mikrobioma rizosfer dalam meningkatkan kesehatan tanah dan produktivitas tanaman pangan serta mengetahui hambatan dan peluang dari mikrobioma rizosfer dalam mendukung pertanian berkelanjutan. Metode penelitian yang digunakan adalah Narrative Literature Review. Rekayasa mikrobioma rizosfer dapat meningkatkan populasi mikroba menguntungkan dengan mengurangi input kimia, tetapi tetap efektif dalam meningkatkan produktivitas tanaman pangan dan kesehatan tanah serta berperan dalam mendukung pertanian berkelanjutan. Penggunaan pupuk dan pestisida harus diatur dengan bijak agar tidak merusak mikrobioma rizosfer dan nutrisi tanah tetap terjaga
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
