Self-boring pressuremeter tests at the National Field Testing Facility, Ballina NSW
No full textAccurate prediction of foundation settlement is increasingly important in onshore and offshore geotechnical design. Reducing land space requires construction on non-ideal soils or above buried infrastructure onshore while offshore shallow foundations require optimization of size to facilitate installation while ensuring tolerances on attached rigid infrastructure such as pipelines are not compromised. The accuracy of settlement predictions depends on the accuracy of the measured soil stiffness, which is non-linear and dependent on stress level, stress path and stress history. Consequently, the quality of a settlement prediction is inherently tied to the relevance of the testing method that is used to derive the stiffness values. The self-boring pressuremeter (SBPM) enables the non-linear stress-strain response to be captured at different in-situ stress levels (depths) over a large range of cavity strain, and derivation of undrained strength, stiffness and creep characteristics. This paper summarizes a program of pressuremeter tests conducted in a soft clay deposit in Ballina, NSW, Australia.</p
Insights from a shallow foundation load-settlement prediction exercise
No full textThis paper describes an international exercise aimed at assessing the geotechnical engineering profession's ability to predict the response of shallow foundations on soft clay subjected to undrained loading. Predictions of bearing capacity varied by more than an order of magnitude and settlement by more than two orders of magnitude. Average and median predicted values deviated significantly from measured values. The results of this exercise highlight the need to develop tools to assist engineers to process site investigation data. The development of predictive models that connect directly to site investigation data is discussed.</p
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
In situtesting at the National Soft Soil Field Testing Facility, Ballina, New South Wales
No full textThe National Soft Soil Field Testing Facility (NFTF) provides a rare opportunity to characterise an Australian soft estuarine clay and to carry out monitored field tests that can be forecast or back-figured using the extensive characterisation data to improve engineering design methods. Several in situ testing campaigns have been performed to characterise the site, to advance full-flow penetrometer technology, to investigate correlations between in situ and laboratory tests and to develop engineering parameters and to assess the variability of the ground. A description of the tools and methods used in the testing campaign is provided in this paper along with a preliminary interpretation from the testing campaigns.</p
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
