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
ANALISIS HIDROLOGI KAWASAN DAS BLONGKENG PROPINSI JAWA TENGAH TAHUN 1993 - 2000
Get PDFBlongkeng watershed area is a sub watershed of Progo, located in Magelang District, Center Java Province. Blongkeng watershed is potential catchment area and it contributes on availability of water surface as well as ground water, either locally and regionally. In accordance with Government Act No. 47/1997 which covers National Planning on Regional Space Arrangement, the middle slope to the up-zone of the watershed has been classified as a conservation region especially on water and soil reserve. This study was conducted so as to determine of hydrology characteristics and watershed critical evaluation. Analytical study covered trend analysis and statistical analysis. The results showed that trend of increasing either maximum and maximum-minimum ratio of stream flow, or trend of declining annually average and minimum stream flow. The evaluation of watershed condition with run-off coefficient (C) analysis showed that the watershed was still norma
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
Analisis Perubahan Penggunaan Lahan dan Evaluasi Kekritisan DAS Kawasan Das Blongkeng Jawa Tengah Tahun 1993 - 2000
Get PDFDAS Blongkeng merupakan Sub DAS Progo, terletak di Kabupaten Magelang dan Boyolali Propinsi Jawa Tengah, dan merupakan daerah tangkapan hujan yang cukup potensial secara lokal dan regional. Berdasarkan PP 47/1997 tentang Rencana Tata Ruang Wilayah Nasional, lereng tengah-atas DAS diklasifikasikan sebagai kawasan konservasi tanah dan air. Peningkatan jumlah penduduk serta aktivitas pembangunan selama tahun 1993 – 2000 telah mendorong terjadinya konversi lahan menjadi lahan terbangun. Hal ini akan mengganggu fungsi kawasan sebagai kawasan lindung dan konservasi. Tujuan penelitian adalah mengetahui luasan konversi lahan yang sudah terjadi, serta evaluasi kekritisan DAS yang dilakukan dengan pendekatan Model Indeks Konservasi (IK). Metode analisis meliputi: pembobotan dan analisis peta dengan SIG. Penelitian menunjukkan terjadi konversi lahan sebesar 10,94%, terutama untuk permukiman, lahan kosong, dan kebun. Lahan yang mengalami penyusutan adalah sawah, hutan, dan tegalan/ladang. Meskipun hasil evaluasi kondisi DAS menunjukkan kondisi DAS masih normal, akan tetapi ditemukan lahan kritis sebesar 1,51% yang perlu segera diatasi dengan metode konservasi lahan yang sesuai dengan kondisi fisik dan sosial-budaya setempa

Get PDFAt the implementation of the national development in reformation era, agriculture sectors becomes dominantsector that contributes national income and they are still the major occupation of Indonesian. These sectorsare mainly done in rural areas, therefore, the study of agriculture sectors is dealt with the study of thedevelopment rural areas. The development rural areas is in many aspects, until now, it is relatively less thanit is in the development in urban areas. In developing these sectors, it needs the strategies of therevitalization of agriculture sectors though the application of agro-industry systems, agribusiness, and theintegrated agropolitan concept with the supporting infrastructur

Get PDFPembangunan Nasional Negara Indonesia yang tujuan umumnya adalah untuk mewujudkan kesejahteraan rakyat dan pemerataannya di seluruh wilayahnya, sampai dengan saat ini masih banyak timbul masalah. Salah satu masalah yang masih dijumpai adalah belum berkembangnya wilayah perbatasan antar wilayah administrasi dalam Negara Indonesia. Wilayah perbatasan selama ini identik dengan wilayah perdesaan, wilayah pertanian, wilayah miskin, dll. Untuk pengembangannya diperlukan kebijaksanaan yang sesuai secara lokalita, yang disusun berdasarkan hasil identifikasi potensi dan hambatan pengembangan di wilayah perbatasan tersebu
