The writing of this thesis was guided by Mrs. Sri Fajar Ayu, SP, MM, DBA as Chair of the Advisory Committe and Mr. Rulianda P. Wibowo, SP., M.Ec., Ph.D as Member of the Advisory Committe. Marelan District is one of the vegetable supply areas in the market of Medan City. There are three types of vegetables that are generally cultivated by farmers in Marelan District, long beans, spinach, and mustard. In vegetables farming, there are several problems that are always faced by farmers, one of them is price risk which can be seen from fluctuations in vegetable prices in the market. Diversification is an alternative that can be done by farmers to minimize the impact of price risk. Diversification can be done by combine long bean, spinach, and mustard. These combinations will form a portfolio that is expected to reduce the risk of vegetable farming. The purpose of this study was to analyze income and risk in vegetable farming in a specialized and diversification as well as analyze farmers' decision making on portfolios at various levels of risk preferences. This research was done by using the calculation of expected return, standard deviation and coefficient variation of portfolio income and risk. To analyze decision making at various levels of risk preference, the analysis use Stochastic Efficiency With Respect To A Function (SERF) model. The results show that diversification can reduce the risk of specialized farming. Furthermore, changes in farmers' risk preferences will change farmers' decision making in portfolio selection.Dian Pebriyani (177039018) dengan judul tesis “Analisis Pendapatan dan Risiko Pada Portofolio Usahatani Sayuran”. Penulisan tesis ini dibimibing oleh Ibu Sri Fajar Ayu, SP, MM, DBA sebagai Ketua Komisi Pembimbing dan Bapak Rulianda P. Wibowo, SP., M.Ec., Ph.D sebagai Anggota Komisi Pembimbing. Kecamatan Marelan merupakan salah satu daerah pemasok sayuran di pasar Kota Medan. Terdapat tiga jenis sayuran yang umumnya diusahakan oleh petani di Kecamatan Marelan yaitu kacang panjang, bayam, dan sawi. Dalam berusahatani sayuran terdapat beberapa masalah yang selalu dihadapi oleh para petani, salah satunya adalah risiko harga yang dapat dilihat dari fluktuasi harga sayuran dipasaran. Diversifikasi usahatani merupakan alternatif yang dapat dilakukan oleh petani sayuran untuk meminimalisir dampak dari risiko harga. Diversifikasi usahatani dapat dilakukan dengan mengkombinasikan tanaman kacang panjang, bayam, dan sawi dimana kombinasi ini akan membentuk suatu portofolio yang diharapkan dapat menurunkan risiko dari usahatani sayuran. Tujuan penelitian ini adalah untuk menganalisis pendapatan dan risiko pada usahatani sayuran secara spesialisasi dan secara diversifikasi, serta menganalisis pengambilan keputusan petani terhadap portofolio pada berbagai tingkat preferensi risiko. Penelitian ini dilakukan dengan menggunakan perhitungan expected return, standart deviation dan coefficient variation untuk menghitung pendapatan dan risiko portofolio. Selain itu untuk menganalisis pengambilan keputusan pada berbagai tingkat preferensi risiko digunakan alat analisis Stochastic Efficiency With Respect To A Function (SERF). Hasil penelitian menunjukkan bahwa dengan melakukan diversifikasi maka risiko dari usahatani secara spesilaisasi dapat diturunkan. Selanjutnya perubahan preferensi risiko petani akan mengubah pengambilan keputusan petani dalam pemilihan portofolio.107 HalamanTesis Magiste
Peran Ganda Istri Nelayan dan Kontribusinya terhadap Pendapatan Keluarga (Kasus: Desa Pekan Tanjung Beringin, Kecamatan Tanjung Beringin, Kabupaten Serdang Bedagai)
No full textTujuan penelitian adalah untuk menjelaskan penggunaan waktu istri nelayan
untuk urusan rumah tangga dan untuk bekerja/berusaha, menjelaskan kontribusi
pendapatan istri nelayan yang berperan ganda terhadap pendapatan keluarga, dan
menganalisis pengaruh faktor-faktor yang memotivasi istri nelayan untuk
berperan ganda terhadap pendapatan istri nelayan.
Penelitian ini dilaksanakan di Desa Pekan Tanjung Beringin, Kecamatan Tanjung
Beringin, Kabupaten Serdang Bedagai. Penentuan daerah penelitian dilakukan
secara purposive. Metode pengambilan sampel yang digunakan adalah purposive
sampling sesuai dengan kriteria yang dibutuhkan dalam penelitian. Data yang
dikumpulkan adalah data primer yang didapat langsung dari responden.
Hasil penelitian menunjukkan bahwa (1) Istri nelayan yang berperan ganda secara
umum lebih dominan menggunakan waktunya untuk mengerjakan urusan rumah
tangga. (2) Secara umum pendapatan istri nelayan yang berperan ganda
memberikan kontribusi kecil (<50%) terhadap pendapatan keluarga. (3)
Berdasarkan jenis pekerjaan pendapatan istri nelayan yang membuka usaha
warung dan kedai kopi memberikan kontribusi besar (>50%) terhadap pendapatan
keluarga sedangkan sebagai ART, buruh cuci, dan membantu berjualan
memberikan kontribusi kecil (<50%) terhadap pendapatan keluarga. (4) Faktor faktor yang memotivasi untuk berperan ganda (kebutuhan ekonomi, kebutuhan
sosial dan kebutuhan aktualisasi diri) secara simultan berpengaruh nyata terhadap
pendapatan istri nelayan, namun secara parsial hanya faktor kebutuhan ekonomi
yang berpengaruh nyata.99 HalamanSkripsi Sarjan

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
Appropriate 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
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
