Kesesuaian Habitat bagi Burung Air di Berdasrakan Analisis Spasial di Kecamatan Percut Sei Tuan, Sumatera Utara
No full textHabitat suitability is a habitat component that has an important function for certain groups or individuals. Waterbirds are animals that are easily found in every place and have an important position as natural wealth in Indonesia. As one component of the waterbird ecosystem requires a place or space to find food, drink and breed called habitat. The purpose of this study was to create a habitat suitability map and find out habitat conditions for water birds in Percut Sei Tuan District. This research was conducted in April 2018 until July 2018. Activities to identify land cover, food availability and potential disruption of human activities in the form of roads were carried out by utilizing remote sensing technology. ArcGIS and Erdas are used to determine habitat suitability. Observation of waterbirds was done using the point count method with the help of a hand held counter. The results of the Percut Sei Tuan District research are divided into 8 types of land cover. Settlement is a land cover with the largest area of land which is 6467.578 hectares and the plantation forest is the smallest land area covering 165.859 Ha. The study area is dominated by the unavailability of food with an area of 13495.914 Ha while the availability of high food for waterbirds has an area of 909.903 Ha, medium 2861.816 Ha and a low of 1718.448 Ha. Potential disruption of human activity is high with an area that is at a distance of 600 m from the road has an area of 181.081 Ha. Percut Sei Tuan Subdistrict is mostly in the suitability class not in accordance with the area of 14975.000 Ha. The unavailability of space for waterbirds to find food, drink, nest and breed can cause a decline in the number of waterbird populations.Kesesuaian habitat merupakan komponen habitat yang memiliki fungsi penting bagi kelompok atau individu tertentu. Burung air adalah satwa yang mudah dijumpai pada setiap tempat dan memiliki posisi penting sebagai kekayaan alam di indonesia. Sebagai salah satu komponen ekosistem burung air memerlukan tempat atau ruang untuk mencari makan, minum dan berkembang biak yang disebut habitat. Tujuan dari penelitian ini adalah untuk membuat peta kesesuaian habitat dan mengetahui kondisi habitat bagi burung air di Kecamatan Percut Sei Tuan. Penelitian ini dilakukan pada bulan April 2018 s.d Juli 2018. Kegiatan identifikasi tutupan lahan, ketersediaan makanan dan potensi gangguan dari aktivitas manusia berupa jalan dilakukan dengan memanfaatkan teknologi pengindraan jarak jauh. ArcGIS dan Erdas digunakan untuk mengetahui kesesuian habitat. Pengamatan burung air dilakukan menggunakan metode point count dengan bantuan alat hitung hand held counter. Hasil penelitian Kecamatan Percut Sei Tuan terbagi menjadi 8 tipe tutupan lahan. Pemukiman merupakan tutupan lahan dengan luas area terbesar yaitu 6467.578 Ha dan hutan tanaman merupakan tutupan lahan dengan luas terkecil yaitu 165.859 Ha. Wilayah penelitian di dominasi oleh tidak tersedianya makanan dengan luas 13495.914 Ha sedangkan ketersediaan makanan tinggi bagi burung air memiliki luas area 909.903 Ha, sedang 2861.816 Ha dan rendah 1718.448 Ha. Potensi gangguan aktivitas manusia tinggi dengan luas area yang berada pada jarak 600 m dari jalan memiliki luas area 181.081 Ha. Kecamatan Percut Sei Tuan sebagian besar berada pada kelas kesesuaian tidak sesuai dengan luas area 14975.000 Ha. Tidak tersedianya ruang bagi burung air untuk mecari makan, minum, bersarang dan berkembang biak dapat menyebabkan turunnya jumlah populasi burung air.Skripsi Sarjan
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
