Site 1221
No full textSite 1221 (12°01.999´N, 143°41.572´W; 5175 meters below sea level (mbsl); Fig. F1) forms an equatorial component of the 56-Ma transect drilled during Leg 199 and is situated about three-quarters of the way between the Clipperton and Clarion Fracture Zones in typical abyssal hill topography. On the basis of regional magnetic anomalies, we anticipated the basement age at Site 1221 to be equivalent to Chron C25n (~56 Ma) (Cande et al., 1989), about the same age as Site 1220. At the outset of drilling at Site 1221, our estimate for total sediment thickness was ~150 meters below seafloor (mbsf) (Fig. F2).
Based upon a fixed hotspot model (Gripp and Gordon, 1990, for the 0- to 5-Ma Pacific hotspot rotation pole; Engebretson et al., 1985, for older poles), Site 1221 should have been located about 1° south of the equator at 56 Ma (in an equatorial position at ~50 Ma) and ~2°N at 40 Ma. Thus, Site 1221 should have been situated underneath the South Equatorial Current in the early Eocene. A nearby piston core (EW9709-14PC) taken during the site survey cruise recovered >11 m of red clay with the base of the core containing a calcareous radiolarian ooze dated as early Oligocene age on the basis of radiolarian biostratigraphy (Lyle, 2000).
Site 1221 will be used to study equatorial ocean circulation from the late Paleocene through the late Eocene during the early Cenozoic thermal maximum. Sediment records from this site will help to define the carbonate compensation depth (CCD) during the Paleocene-Eocene and Eocene-Oligocene transitions. In this and other respects, Site 1221 will act as an interesting analog to Site 1220. The two sites are situated on similar age crust and exhibit similar seismic-stratigraphic sequences, but Site 1221 is thought to have crossed the equator ~5 m.y. earlier than Site 1220, during latest early Eocene time (~50 Ma)
Antonini, Virginia (FA 1221)
Full text linkFinding aid only for Folklife Archives Project 1221. Student paper titled “Moonshining” in which Virginia Antonini details the process of distilling moonshine from harvest to bottling. Antonini describes the equipment used to produce moonshine and includes several stories told by her informant, a man only referred to as “Jim,” about his methods and various run-ins with the law. The author also includes her mother’s wine recipe and additional “home brew” stories
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
