Aspek Motorisasi sebagai Upaya Peningkatan Produksi dan Pendapatan Nelayan
No full textSumatera Utara mempunyai potensi kelautan yang strategis : memiliki jumlah nelayan yang banyak secara turun temurun di Pantai Timur dan Pantai Barat, mempunyai pulau- pulau yang banyak, mempunyai pantai yang panjang, produksi ikan yang besar dan nilai ekspor yang tinggi. Potensi kelautan tersebut belum dikembangkan secara optimal dan belum dapat dinikmati oleh nelayan karena: (1) Transformasi teknologi, timpang secara struktural dimana teknologi maju hanya dimiliki oleh golongan tertentu dan nelayan tetap dalam kondisi tertinggal. (2) Rendahnya kedudukan nelayan, kurangnya aktivitas dan rendahnya dinamika organisasi nelayan dalam semua aspek. (3) Terbatasnya perhatian dan bantuan kepada masyarakat nelayan.
Keadaan seperti ini tidak dapat dipertahankan lagi secara terus menerus oleh karena perjuangan masa depan dalam era otonomi daerah adalah pengembangan potensi kelautan dengan cara meningkatkan kemampuan nelayan untuk mengelola potensi perikanan.
Tujuan dari penelitian ini adalah untuk mengetahui kombinasi kapal motor dan alat tangkap mana yang menghasilkan profit yang lebih tinggi dan layak untuk dikembangkan serta untuk mengetahui pengaruh faktor produksi, investasi biaya melaut, jumlah hari melaut dan jumlah tenaga kerja terhadap pendapatan nelayan.
Penelitian ini dilakukan di Kecamatan Medan Belawan Kota Medan, yaitu di Kelurahan Bagan Deli atau dikenal juga dengan nama Pelabuhan Perikanan Nusantara Belawan. Penentuan sampel ditetapkan secara sengaja yaitu 17 responden untuk nelayan kapal motor diatas 5 GT, 15 responden untuk nelayan jenis Bot Tempel, dan 15 responden untuk nelayan tradisional.3 HalamanTesis Magiste
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
ANALYSIS OF FERTILIZER PURCHASING DECISIONS FOR PALM OIL FARMERS ON THE INFLUENCE OF TYPE, QUANTITY AND PRICE OF FERTILIZER IN PARDAMEAN LABUHANBATU REGENCY
Full text linkThe aim of this research is to find out how much influence the type of fertilizer, quantity and price of fertilizer has on the decision to purchase fertilizer among oil palm farmers in Perdamean Dalam Village, Rantau Selatan District, Labuhanbatu Regency. In this research, the sample used was 83 oil palm farmers. The data analysis method in this research is quantitative descriptive. The results of this research show that the type of fertilizer, quantity and price of fertilizer have a positive and significant effect on the decision to purchase fertilizer among oil palm farmers in Perdamean Village, Rantau Selatan District, Labuhanbatu Regency, while the type of fertilizer has a positive and but not significant effect on the decision to purchase fertilizer. Based on the results of simultaneous tests, the variables of fertilizer type, quantity and price of fertilizer influence purchasing decisions. Keywords: Fertilizer Type, Price, Purchasing Decision
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
