Get PDFPenelitian ini bertujuan untuk mengetahui produktivitas dan faktor-faktor yang mempengaruhi hasil tangkapan serta tingkat keuntungan usaha penangkapan pada alat Jaring Insang (gill net) dan Salambau (trap net). Penelitian ini dilaksanakan selama 1 (satu) bulan, pada bulan Februari 2018 dengan 4 kali pengambilan sampel. Tempat pelaksanaan di Danau Marang Kelurahan Marang Kecamatan Bukit Batu Kota Palangka Raya. Hasil penelitian yang telah dilaksanakan di Danau Marang dapat disimpulkan bahwa hasil produktivitas dari penangkapan ikan di Danau Marang yang dilakukan selama 1 (satu) bulan penelitian dengan menggunakan alat tangkap jaring insang diperoleh sebanyak 8,67 kg dan Salambau sebanyak 23,33 kg. Perhitungan laba/ rugi, Revenue Cost Ratio (R/C) yang dihitung dalam jangka waktu 1 tahun berdasarkan hasil wawancara terhadap 5 orang nelayan di Danau Marang diperoleh keuntungan/ laba Rp 4.212.000, sedangkan keuntungan relatif usaha (Revenue cost ratio (R/C)) dengan rata-rata 2 sehingga dinyatakan layak karena nilai R/C > 1

Get PDFPenelitian ini tujuannya untuk mengetahui karakter morfometrik dan meristik ikan Tapah yang terdapat di hulu, tengah, dan hilir di Sungai Sebangau. Manfaat dalam penelitian ini karakter morfometrik dan meristik ikan Tapah (W. leeri) yang tertangkap pada 2 (dua) stasiun yaitu stasiun 1 (satu) pengambilan sampel di Ules, stasiun 2 (dua) pengambilan sampel di Karanen. Metode penelitian yang digunakan dalam penelitian ini adalah penelitian deskriptif, regresi linear dan perhitungan. Data primer dimasukkan kedalam sistem database yang menggunakan software Microsoft Excel untuk menganalisis statistik deskriptif, regresi linear dalam bentuk tabel dan grafik. Hasil penelitian dapat disimpulkan: Morfometrik ikan Tapah (Wallago Leeri) di Ules dan di Karanen bahwa hasil analisis persamaan regresi linear karakter morfometrik ikan Tapah betina dan jantan di Ules dan di Karanen memiliki keeratan hubungan sangat kuat, kuat, sedang, lemah dan sangat lemah. status hubungan pola pertumbuhan ikan Tapah betina dan jantan di Ules dan di Karanen memiliki pola pertumbuhan alometrik postif. Ikan Tapah betina dan jantan di Ules dan di Karanen memiliki kondisi kualitas air yang cukup baik dan mendukung pertumbuhan.
The aim of this study is to determine the morphometric and meristic characters of Tapah fish found in the upstream, middle and downstream of the Sebangau River. The benefits of this study are the morphometric and meristic characters of Tapah (W. leeri) fish caught at 2 (two) stations, namely station 1 (one) sampling in Ules, station 2 (two) sampling in Karanen. The research method used in this research is descriptive research, linear regression and calculation. Primary data was entered into a database system using Microsoft Excel software to analyze descriptive statistics, linear regression in the form of tables and graphs. The results of the study can be concluded: The morphometric fish of Tapah (Wallago Leeri) in Ules and Karanen showed that the results of linear regression analysis of the morphometric character of female and male tapah fish in Ules and in Karanen had very strong, strong, moderate, weak and very weak relationships. The relationship status of female and male tapah fish growth patterns in Ules and Karanen had positive allometric growth patterns. Female and male tapah fish in Ules and Karanen have fairly good water quality conditions and support growth
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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

No full textAppropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Get PDFWe 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
