The Petrology and Sedimentation of the Lower Proterozoic Barron Quartzite, Northwestern Wisconsin
No full textA Thesis submitted to the faculty of the Graduate School of the University of Minnesota by Wendy Johnson Rozacky in partial fulfillment of the requirements for the degree of Master of Science, May 1987.The Barron Quartzite of northwestern Wisconsin is a fine-grained, quartz-cemented, buff to red quartz arenite with minor interbedded argillite and a thin basal quartz-pebble conglomerate. The thickness of the Barron is at least 225 m (as shown by drill core) and may be greater than 400 m. Mafic dikes cut the Barron Quartzite but are as yet undated. The primary framework component of the Barron Quartzite is common quartz (75%). Polycrystalline quartz (grains with 2 to 5 component crystals), stretched polycrystalline quartz (composites of numerous suctured crystals), recrystallized polycrystalline quartz (grains made up of numerous. small. polygonal crystals) and vein quartz together make up approximately 16% of framework grains. Multicycle quartz grains (common quartz grains which have optically continuous overgrowths of quartz that have been abraded and surrounded by other overgrowths) are also present. Chert and iron-formation rock fragments occur but are rare. Feldspar is absent. Quartz cement, which occurs as optically continuous overgrowths on quartz grains, is common (approximately 9%) and hematite cement constitutes less than 1%. The heavy mineral suite is composed almost entirely of rounded zircon with minor rounded tourmaline and rutile, and minor magnetite. A possible depositional environment for the Barron Quartzite is a braided alluvial plain which was superseded by a marine shelf environment. Paleocurrent data are variable. Most localities show a unimodal pattern towards the south, indicating sediment transport form north to south. However, polymodal and bimodal-bipolar patterns are also present at some outcrops. A unimodal pattern probably indicates a fluvial depositional environment while a bimodal-bipolar pattern could suggest a tidally-influenced marine depositional environment. The Barron Quartzite is probably correlative with several of the other Precambrian quartzites in the Lake Superior region, including the Baraboo, Sioux, Flambeau, Waterloo, and McCaslin Quartzites. Of these, the Baraboo is the best dated, probably having been deposited between 1760 and 1630 Ma (Van Schmus. 1978; Van Schmus and Bickford. 1981).Rozacky, Wendy Johnson. (1987).

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
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
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
