Water column raw data (Kongsberg EM 122 entire dataset) of RV SONNE during cruise SO247
No full textWater column raw data using the ship's own Kongsberg EM 122 multibeam echosounder was not continuously recorded during RV SONNE cruise SO247. Data was recorded on 22 days between 2016-03-27 and 2016-04-25. This dataset contains a survey east of New Zealand (North Island) covering mostly the continental slope.
The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie, BSH) and provided to PANGAEA database for data curation and publication. Ancillary sound velocity profiles (SVP) files from the cruise are archived at the BSH and archived at the corresponding multibeam raw dataset https://doi.org/10.1594/PANGAEA.942418.
This publication is conducted within the efforts of the German Marine Research Alliance in the core area "Data management and Digitalization" (Deutsche Allianz Meeresforschung, DAM)
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
Tectonic history of Antarctic seafloor in the Australia-New Zealand-South Pacific sector: implications for Antarctic continental tectonics
No full textWe review the seafloor spreading record of plate motions adjacent to the Antarctic continent during and after Cretaceous separation of the New Zealand and Australia continental fragments from Antarctica. The earliest seafloor in this region (c. 95-83 Ma) records separation of Australia from Antarctica and separation of the Lord Howe rise from eastern Australia. At this time, continental extension occurred between the Campbell Plateau/Chatham Rise and Marie Byrd Land with oblique subduction of Phoenix plate fragments (Aluk and Bellingshausen) beneath the West Antarctic margin from c. 125ºW to at least 90ºW. Seafloor spreading started first (Chron 34, before 83 Ma) in the mouth of the rift, between the Chatham Rise and the Bellingshausen plate, and later (Chron 33, c. 79 Ma) between the Campbell Plateau and Marie Byrd Land, joining the Tasman sea ridge to the southwest Pacific spreading centre. Subsequent tectonic events include: (1) <50 km of rifting of the seafloor adjacent to Marie Byrd Land along the northeast-trending Iselin trough, east of the Iselin Bank, from Chrons 27 to 24 (61-55 Ma); (2) propagation of the southeast Indian Ridge between the south Tasman Rise and Victoria Land to join the Tasman Sea spreading centre by Chron 27 (61 Ma); (3) capture of the Bellingshausen plate by West Antarctica by about Chron 27; (4) 150-180 km of separation between East Antarctica and West Antarctica (Iselin Bank) centred on the NNW-trending Adare trough between Chrons 18 and 9 (40-27 Ma). These observations predict, first, that the West Antarctic margin at 125ºW was the site of a triple junction from at least 84 to 61 Ma, with Phoenix plate annihilation and expected tectonics of West Antarctica in many ways analogous to breakup of the Farallon plate and its effects on western North America. Second, northern Victoria Land may exhibit unique tectonics compared to elsewhere along this part of the Antarctic margin because it lay in a continental strike-slip regime, sliding against continental crust of the Australia plate (western south Tasman Rise) until Eocene time. Finally, the 150+ km of Oligocene seafloor formed at the Adare Trough implies a significant extensional event of this age farther south in the Ross Sea, in agreement with results from recent drilling at Cape Roberts hole CRP-3
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
