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
Bend-strength of wound carbon fibre reinforced polymer shear reinforcement
No full textThe filament winding of Fibre Reinforced Polymer (FRP) tows around longitudinal reinforcing bars provides a novel method for the fabrication of shear reinforcement cages. A key limitation on the contribution of FRP to the shear capacity of a concrete member is found at corners, where the presence of stress concentrations in different directions can lead to premature failure. Current methods to test FRP reinforcement at corners have limited use for filament wound reinforcement. A new test methodology was developed to allow for rapid testing of curved FRP reinforcement that allows for sample re-alignment during load application, reducing the effects of eccentricities. An experimental programme, comprising of 8 test samples, was undertaken to assess the bend capacity of wound Carbon FRP (CFRP) shear links, considering three variations in bend radius and two variations of cross sectional area. It was found that an increase in bend radius resulted in increase in failure load. It was also observed that an increase in cross sectional area led to a decrease in the ratio between the bend capacity and the ultimate tensile capacity. From comparison between the experimental results and values from theoretical bend strength estimations, it was established that further developments of bend strength predictions for wound shear reinforcement are required in order to accurately reflect their behaviour

New frontiers for the use of FRP reinforcement in geometrically complex concrete structures
No full textThe development of flexible formwork has made it possible to cast optimised geometrically complex and thin walled reinforced concrete structures. At the same time, advanced composite materials offer the opportunity to solve the problem of steel corrosion, which can affect aging of concrete structures. With the goal of achieving sustainable design, being able to combine optimised geometries with durable construction materials is a major challenge for civil engineering. New research at the University of Bath and the University of Miami aims to completely replace internal steel reinforcement in geometrically complex concrete structures with durable and ready-to-use cages made of fibre reinforced polymer (FRP) reinforcement. By fabricating the reinforcement in the desired geometry, it will be possible to provide the required strength exactly where needed, thereby reducing the amount of concrete required to resist internal forces and capitalizing on the extraordinary possibilities offered by both concrete and FRP construction materials. The design of such optimized elements and the automated process of manufacturing the Wound FRP (W-FRP) reinforcement are presented in this paper
Bend-strength of novel filament wound shear reinforcement
No full textThe winding of Fibre Reinforced Polymer (FRP) tows around longitudinal reinforcing bars provides a novel method for the fabrication of reinforcement cages. Complex geometries of internal reinforcement can be fabricated using this technique, a particular advantage for the construction of optimised concrete beams. A key limitation on the contribution of FRP to the shear capacity of a concrete member is found at corners, where the presence of stress concentrations in different directions can lead to premature failure. A new test methodology was developed to allow for rapid testing of the samples as well as sample re-alignment during load application, reducing the effects of eccentricities and imperfections created during their fabrication. An experimental program, comprising 30 test samples, was undertaken to assess the bend capacity of filament wound FRP (W-FRP) shear links manufactured using a carbon tow impregnated with epoxy resin. A fixed bend radius of 5 mm and six non-circular fibre cross sectional areas having different width-thickness ratios were considered. Additionally, 18 samples were tested to measure the tensile properties of the straight reinforcement. The test results indicate that W-FRP shear links exhibit improved bend strength as compared to conventional stirrups with circular sections (up to +53%), as a larger width-thickness ratio of the reinforcement provided more strength for a given cross sectional area. A good correlation between the test results and predictions of the W-FRP bend strength was observed when the specimens were modelled as a collection of transformed individual circular sections
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
