    NOC turbulence glider deployment report for the OSMOSIS Project

    Full text link
    This document summarises the three deployments of the NOC Liverpool Teledyne Webb Research Slocum glider fitted with an external Rockland Scientific International micro-Riderturbulence probe during September 2011. The general aim of these glider deployments was to generate underwater turbulence and glider based CTD measurements for comparison with other sensor systems. This information will be used for evaluation of the performance of other measurement systems that are required for the Ocean Surface Mixing, Ocean Submesoscale Interaction Study (OSMOSIS) research project. All of the measurement systems were deployed in close proximity to a series of moorings that had a nominal centre location of 55O 46.92”N, -5O 12.6”W. Turbulence measurements used for comparison with the glider were recorded using a ship based Rockland Scientific International (RSI) Vertical Microstructure Profiler (VMP) and a REMUS 600 AUV with a RSI turbulence measurementpackage installed. The survey work described in this document was designed to act as a test and rehearsal for the use of the sensor systems that will be required for a Celtic Sea shelf edge based research cruise for the OSMOSIS project. The shelf edge cruise is scheduled to take place during 2012.An overview of the aims of each glider deployment and the subsequent glider performance is included. The glider deployments in Scotland culminated in co-located survey on Thursday 15th September 2011 that involved all of the OSMOSIS sensors, AUVs, moorings and ship based measurement systems operating in the same general location at the same time. This document concludes with a summary of the glider performance and recommendations are made regarding the scheduling and format for future scientific campaigns that require the use of the NOCL gliders

    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

    NOC turbulence glider deployment report for the Liverpool Bay Coastal Observatory, June 2011 Deployment

    Full text link
    A summary of the NOC Liverpool turbulence glider deployment that occurred between Tuesday 28th June and Monday 4th July 2011 is provided in this document. The general objective of the deployment was to hold the glider on station at a nominal GPS location of 53o 48”N, -4o 00”W to provide a series of glider based turbulence probe and CTD data profiles. These profiles were initiated when the glider reached a nominal depth of 40 metres and continued until the glider approached the sea surface. The glider deployment site was selected to be away from the influence of fresh water influx into the Liverpool Bay and in aposition that avoids scheduled shipping routes. The recorded glider data was compared with a seabed instrumentation frame that was deployed at the same nominal location. The instrumentation frame had a Seabird CTD and a 5 axis upward measuring ADCP with a vertical turbulence measurement capability installed. During the glider deployment cruise reference water samples and independent CTD measurements were collected for deployed instrumentation and glider sensor calibration purposes

    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

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    We 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
