Consolidation, effective stress, and fluid pressure of sediments from ODP Site 174-1073
No full textFluid pressure interpreted from uniaxial consolidation tests equals 80% of the overburden (total) stress in Pleistocene mudstones at Ocean Drilling Program (ODP) Site 1073 of the US mid-Atlantic continental slope, offshore New Jersey. The fluid overpressure decreases effective vertical stress and preserves void ratio (e) greater than 0.8 in Pleistocene sediments. Overpressure in Oligocene-Miocene sediments is lower even though e is high. Cementation preserves high void ratio of Oligocene-Miocene sediments and therefore the void ratio does not record overpressure and low effective vertical stress. Sedimentation-flow models simulate overpressure and high void ratio in the Pleistocene sediments when fluid flow is coupled with sediment loading at ODP Site 1073. Lateral fluid migration is interpreted to be focused in the Oligocene-Miocene sediments, which are 2.5 times more permeable than the overlying Pliocene-Pleistocene mudstones. The lateral flow provides fluids to ODP Site 1073 to maintain high void ratio, high overpressure, and low effective vertical stress
Calcareous nannofossil abundance of ODP Sites 174A-1071, 174A-1072 and 174A-1073
No full textCalcareous nannofossil range charts for Leg 174A sites on the New Jersey continental margin are presented in this report, and nannofossil biostratigraphy is established. Nannofossil biostratigraphic resolution is low in shallow-water Sites 1071 and 1072, where nannofossils are generally rare or frequently absent. Site 1073 yields generally common to abundant nannofossils, which allows a fairly detailed nannofossil biostratigraphy for the entire Pleistocene through upper Eocene sequence. Quantitative and semiquantitative nannofossil data for the upper Pleistocene section from Site 1073 reveal an average sedimentation rate of about 80 cm/k.y. The unusually high sedimentation rate makes this calcareous section very valuable for high-resolution studies

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

5. Site 1073
Full text linkSite 1073 constitutes one of four second-priority sites approved for drilling that were to be undertaken in the event that either time allowed or that operations had to be curtailed at both primary shelf sites. With 5 days remaining on Leg 174A, the decision was made to move to the slope, because it seemed unlikely that at Sites 1071 and 1072 it would be possible to reach objectives deeper than surface m1(s) without unreasonable risk of equipment loss because of unstable hole conditions. Site 1073 was designed to drill as deeply as time would allow into “Icehouse” sediments (Oligocene and younger) at a location where the physical stratigraphy could be related to sequence boundaries traced seaward from the shelf. The objective at Site 1073 is to provide the age and deep-water facies control for surfaces that in shallow water can yield paleobathymetry and facies characterization relevant to determining the history and geologic impact of glacial-eustatic change
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
