Keanekaragaman Jenis Ikan Di Perairan Pasang Surut Sungai Musi Kecamatan Muara Telang Kabupaten Banyuasin
Penelitian ini telah dilaksankan pada bulan April-Mei 2024 di kawasan irigasi perairan pasang surut sungai musi, Kecamatan Muara Telang, Kabupaten Banyuasin. Tujuan penelitian ini yaitu untuk mengevaluasi nilai indeks keanekaragaman jenis ikan yang hidup dikawasan irigasi perairan pasang surut sungai musi. Penelitian ini menggunakan metode purposive sampling dengan 3 stasiun pengamatan. Hasil penelitian menunjukkan bahwa pada stasiun 1 ditemukan sebanyak 74 individu yang terdiri atas 8 spesies dan 8 famili, pada stasiun 2 ditemukan sebanyak 51 individu yang tergolong kedalam 9 spesies dan 6 famili, sedangkan stasiun 3 terdapat 38 individu yang terdiri dari 7 spesies dan 7 famili. Secara keseluruhan, nilai total indeks keanekaragama jenis ikan dikawasan irigasi perairan pasang surut sungai musi yaitu sebesar 5,89 yang termasuk dalam kriteria tinggi.
This research was conducted on April-May 2024 in the tidal water irrigation area of the Musi River, Muara Telang District, Banyuasin Regency. This study aims to analyze the fish diversity in the tidal irrigation area of the Musi River. This research used the purposive sampling method with 3 observation stations. The results showed that as many as 74 individuals at station 1 consist of 8 species grouped in 8 families, at station 2 as much as 51 individuals consist of 9 species grouped in 8 families, and than at station 3 there were 38 individuals consist of 7 species grouped in 7 families. Overall, the fish diversity index value in the tidal water irrigation area of the Musi River is 5.89, which are included in the high criteria diversity
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
Karakteristik Kandungan Kimia dan Komponen Bioaktif Rumput Laut Hijau Halimeda sp. Dari Kepulauan Seribu
Halimeda sp is a green seaweed belonging to the order Bryopsidales, class Chlorophyta. Production data from the genus Halimeda sp in Indonesia yet has not been reported by the Ministry of Fisheries and Marine Affairs because it belonged to the unknown type of potential. The purpose of this study was to determine the chemical and bioactive components of Halimeda green seaweed. The chemical components of seaweed Halimeda sp included of moisture content, ash, protein, fat, and carbohydrates (by different). Analysis of bioactive components was carried out qualitatively and quantitatively by counted total phenol. The results showed that the proximate analysis of Halimeda sp contained 3.15% moisture content, 87.61% ash content, 0.2% protein content, 1% fat content, and 11.19% carbohydrate (by different) content. Qualitatively Halimeda sp positively contains steroid and alkaloid compounds and was negative for flavonoids, phenols, tannins, saponins, and triterpenoids. The quantitative analysis of the total phenol content of Halimeda sp. extracted with 99.9% ethanol solvent was 273.88 mg GAE/g
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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
We 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
