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

Full text linkSeveral natural phenomena especially at coastal zone that later become natural disaster in our daily life, among others are flooding, high water-tide flood (known locally as “rob”), land slide, mount eruption, tsunami waves and specific natural phenomena that happened at Semarang coastal city was land-subsidence. Aims of the research are field measurement of actual land-subsidence, by means of land height differences by time and built a spatial plot and data base. Field measurement was done with measurement of land height differences by means of land-height differences based 60 Geodetic Land Height positions set by Indonesian Bireau of Land Mapping (Titik Tinggi Geodesi -Bakosurtanal) and private Bench Mark (BM) at Semarang, with its geodetic positions by GPS (Global Positioning System).
Both field and geodetic data collected was then transformed into a numeric series of data to be processed for geostatistic known as Kriging method become a raster layer data, that later used for spatial analysis using ER_Mapper 6.4 (Licensed user) and Arc_GIS software. Geodetic datum used was WGS84 on UTM map projection. Beside the field data that transformed into a arster layer data, a Spaceshuttle Radar for Terrain Model (SRTM) data for contur and 3 dimention analysis and a Landsat_ETM satellite data was also used as value added to the data (metadata).
Based on the analysis of field data measurement and spatial plot revealed that the rate of land-subsidence at Semarang coastal city ranged from 1 – 9 cm/year, widely distributed throughout the city, espescialy at the most densed populated zone. Therefore a remapping and re-evaluation of the City Spatial Planning and Regulations was inevitable
PEMETAAN DINAMIS EKOSISTIM IKAN PELAGIS MELALUI TEKNOLOGI INDERAJA DI PERAIRAN LAUT INDONESIA Studi kasus Perairan dalam (Utara Irian Jaya) Dan Perairan Dangkal (Kangean)
Full text linkTujuan penelitian adalah pemetaan secara dinamis ekosistem ikan
pelagis kecil di perairan dangkal dan ekosistem ikan pelagis besar di perairan
dalam melalui pendekatan analisis terpadu “ karakter-ekosistem’ dan
‘karakter-spektral’ inderaja pada musim yang berbeda (pendekatan ‘spatiotemporal’).
Selama ini penelitian di laut dilakukan sendiri-sendiri sesuai
dengan keperluan instansi masing-masing. Sehingga sulit mengetahui dan
menganalisa karakter ekosistem serta memetakan sumber hayati laut itu
secara terpadu sebagai suatu ekosistem yang utuh. Penelitian inderaja yang
dilakukan selama ini selalu diartikan atau bersifat ‘pembenaran bumi’ (seatruth)
terhadap data ‘waktu sebenarnya’ (real-time) yang kenyataannya sulit
dilakukan serta belum memberikan informasi dasar secara utuh dan
menyeluruh. Digunakan metoda ‘pembenaran bumi’ juga dilakukan metoda
‘karakterisasi suatu ekosistem dalam periode dan wilayah tertentu’ (spatiotemporal).
Aspek inderaja lebih ditekankan pada analisis-spektral.
Penelitian difokuskan untuk mengetahui karakter ekosistem perairan
dangkal (Kep. Karimunjawa) dan perairan dalam (Utara Irja) pada musim
berbeda. Aspek inderaja ingin diketahui ‘spektral-spesifik’ band-2, 3, 4 dan 7
dan Landsat-TM dan band-1, band-2 data Hasil penelitian adalah informasi
dasar dalam penyusunan model algoritma peramalan. Validasi hasil penelitian
melalui uji korelasi antara data inderaja terhadap data biomas ikan (data
akustik ‘Fish-Finder’ untuk perairan dalam Utara Irja) dan data hasil
tangkapan ikan langsung bersama kapal ikan KM Tunas Samodra, Juwana-Pati
(untuk perairan dangkal Kep. Kangean). Data perairan (ekosistem) meliputi
data nir-hayati yaitu suhu, kedalaman, salinitas, hara nitrat dan fosfat dan
parameter hayati seperti klorofil-a, jenis dan dominasi baik fito dan
zooplankton, larva dan biomasa ikan. Metoda pengambilan atau pengukuran
data adalah secara horizontal di permukaan dan secara vertical pada kolom
air, untuk mengetahui pola pergerakan dan percampuran masa air
