    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Visible Infrared Imager Radiometer Suite (VIIRS) Active Fires Application Related Products (AFARP) Generation Using Community Satellite Processing Package (CSPP) Software

    This paper present a Suomi National Polar-orbiting Partnership (S-NPP) satellite Visible Infrared Imager Radiometer Suite (VIIRS) instrument data processing system design to produce Active Fires Application Related Product (AFARP). Community Satellite Processing Package (CSPP) Environmental Data Record (EDR) software version 1.0 release was used as the processing core. Total average processing time required by the system to produce AFARP from rawdata level is 35 minutes 53 seconds. Hence, the system can be considered to be developed in the future so it can process from rawdata level to AFARP automatically because the average processing time still less than two subsequent S-NPP satellite data acquisition time in one day (1 hour 39 minutes 21 seconds). Storage system volume that will be be needed to accomodate the whole AFARP files until the predicted satellite's mission life over is about 164.88 Gigabytes

    Variations on the Author

    “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 link
    We 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

    Land, ocean and atmosphere remote sensing data are collected by Suomi National Polar-orbiting Partnership (S-NPP) satellite and distributed to its users as responsibility of easurements continuity that are needed to bridge between current National Aeronautics and Space Administration (NASA) Earth Observing System (EOS) and future low-Earth orbiting weather and environmental observation satellite systems (Joint Polar Satellite System /JPSS). Since May 2012, LAPAN's remote sensing ground station acquires S-NPP satellite data in Direct Broadcast (DB) mode. This paper present a novel S-NPP satellite data processing system built to provide Sensor Data Records (SDR) data sets from Raw Data Records (RDR)data sets that have been stored in LAPAN's data storage system. Open source operating system and softwares was used with the Community Satellite Processing Package (CSPP) software package as the system core. Average processing time that is required by the system to processed RDRs to SDRs (including quicklook images) is 32 minutes 19 seconds. Storage system volume that will be needed to accomodate the whole S-NPP satellite data in SDR leveluntil the satellite's mission life over is about 22,298 Terabytes. For the first time, the system provides SDRs products from S-NPP data satellite for Indonesian region overpass ndependently.Hlm. 56-6

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    We 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

    Visualization System Of Monthly Average Sea Surface Temperature Modis Using KML In Google Earth

    No full text
    It has been built and developed a system of sea surface temperature (SST) data viewer ofmonthly Aqua-MODIS data using Google earth API and kml script. This product is useful forease in visualizing Aqua-MODIS SST data. Daily MODIS data are very dependent on the cloudscover condition, so it will be very difficult to monitor the SST conditions only with daily data.With monthly average data, monitoring sea temperature conditions can be optimized. Aqua-MODIS data used are the daily data in HDF format from April 2010 to date, but that will bediscussed in this paper only until April 2014. A composite of daily data into monthly data wasdone by calculating the average of each image pixel with the entire daily data during the month. Before performing the composite process, each daily data was overlaid with the cloud mask data to obtain cloud-free data. Based on monthly data, the percentage of cloud cover average was 25.09 %, with the average amount of data used to make monthly composite image was about 36 daily data. The development of this system was done in the Linux operating system using the reprojection software for Aqua-MODIS data and our developed software in C language for doing composite, as well as gdal software to convert hdf to kml format.Hlm.447-45
