Cone penetration data, Sand pit - Cuxhaven Germany
No full textThe datasets includes 12 vertical cone penetration profiles providing cone resistance, sleeve friction and pore water pressure. CPTs have been conducted in 2019 in a sand pit near Cuxhaven (Germany) which is a part of the geological and glacial formed Geest Moraine Ridge of northern Germany. The CPTs have been used to estimate the axial pile capacities of displacement piles located nearby
Interface direct shear test data for developing maximum peak and constant volume shear angle in dependency to the roughnesses of the surfaces
No full textThe dataset contains the shear displacement data of more than 100 direct shear tests (constant normal load). Naturally corroded, 35 different steel surface have been sheared against a also natural quartz sand (Cuxhaven Sand). Mean center-line surface roughness of interfaces is provided
88 Load displacement curves generated by static pile tension loading including aging characteristics
No full textDatasets represents load displacement data of 44 piles tested by static tension loading for their axial capacity. Each pile was tested two times. Firstly, 24 h after installation and for a second time after a distinct aging time of 1,10 or 100 days. Piles have been installed by various installation methods i.e. impact driving (ID), jacking (J) or two types of pile vibration. For impact driven piles, two kinds of steel have been used.
The data sets represent the load displacement data of 44 piles that were tested for axial load capacity by static tensile loading. Each pile was tested twice. First, 24 hours after installation and second, after a specified aging period of 1, 10, or 100 days. The piles were installed by different installation methods, i.e., impact driving (ID), jacking (J), or two types of pile vibration (Vcss1 & Vcss2). Two types of steel (mild and stainless steel) were used for impact driven piles
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
