Seismic retrofitting of RC buildings using CFRP and post-tensioned metal straps: shake table tests

This article examines the effectiveness of two innovative retrofitting solutions at enhancing the seismic behaviour of a substandard reinforced concrete building tested on a shake table as part of the Pan-European funded project BANDIT. To simulate typical substandard construction, the reinforcement of columns and beam-column joints of the full-scale structure had inadequate detailing. An initial series of shake table tests were carried out to assess the seismic behaviour of the bare building and the effectiveness of a first retrofitting intervention using Post-Tensioned Metal Straps. After these tests, columns and joints were repaired and subsequently retrofitted using a retrofitting solution consisting of Carbon Fibre Reinforced Polymers and Post-Tensioned Metal Straps applied on opposite frames of the building. The building was then subjected to unidirectional and three-dimensional incremental seismic excitations to assess the effectiveness of the two retrofitting solutions at improving the global and local building performance. The article provides details of the above shake table testing programme and retrofitting solutions, and discusses the test results in terms of the observed damage, global damage indexes, performance levels and local strains. It is shown that whilst the original bare building was significantly damaged at a peak ground acceleration (PGA) of 0.15g, the retrofitted building resisted severe threedimensional shake table tests up to PGA=0.60g without failure. Moreover, the retrofitting intervention enhanced the interstorey drift ratio capacity of the 1st and 2nd floors by 160% and 110%, respectively. Therefore, the proposed dual retrofitting system is proven to be very effective for improving the seismic performance of substandard buildings.

Full-Scale Shaking Table Tests on a Substandard RC Building Repaired and Strengthened with Post-Tensioned Metal Straps

The effectiveness of a novel Post-Tensioned Metal Strapping (PTMS) technique at enhancing the seismic behaviour of a substandard RC building was investigated through full-scale shake-table tests during the EU-funded project BANDIT. The building had inadequate reinforcement detailing in columns and joints to replicate old construction practices. After the bare building was initially damaged significantly, it was repaired and strengthened with PTMS to perform additional seismic tests. The PTMS technique improved considerably the seismic performance of the tested building. Whilst the bare building experienced critical damage at an earthquake of PGA=0.15g, the PTMS-strengthened building sustained a PGA=0.35g earthquake without compromising stability.

“Should we all be on Marx’s side?” Contributions of post-marxist discourse theory to the historiography of communism

Drawing on post-marxist discourse theory inspired by the writings of Ernesto Laclau and Chantal Mouffe, this article puts the case for a literature on communism situated at the crossroads of critical theory, cultural studies and historiography. Specific illustration is provided by the author's own research on British communism and the Spanish Civil War. However, the scope of the article is much broader and it is intended as a contribution to the theoretical discussion of future possibilities for communist history-writing. The article concludes that discourse should be regarded neither as a flat surface of tightly knit signifiers nor as an impenetrable monolith of meaning systems. Rather, it should be seen as an inherently dynamic phenomenon, with its own condensations and dispersions along the historical continuum. In this lies its significance for historians of communism.

Examining how post-secondary L2 readers make use of background knowledge when reading literary texts an exploratory study

Literary texts offer rich opportunities for language learning. However, can second language (L2) learners fully understand L2 literary texts? According to Bernhardt (2001):"the act of reading in a second language is extremely tricky -- is even trickier with literary texts that are inherently ambiguous, full of metaphor and intertextual relations to texts to which the readers have no access" (p.198). In other words, L2 readers are often poorly equipped grammatically, linguistically and culturally to cope with literary texts in which it might be difficult to recognize figurative language, to comprehend metaphors, to identify underlying cultural assumptions and above all to think critically while navigating those complexities. Therefore, during the reading process, L2 readers encounter gaps in the text which necessarily compel them to use whatever background knowledge they possess in order to create meaning. The purpose of this research is to see exactly how post-secondary L2 readers use their existing background knowledge to understand literary texts and what they do when confronted with text passages for which they lack such knowledge.

Évaluation prospective de l’état nutritionnel et risque de complications post-opératoires de la cystectomie radicale

La cystectomie radicale est le traitement de référence pour les cancers de la vessie infiltrant le muscle. Cette chirurgie entraine un taux élevé de complications et diminue la qualité de vie des patients à court et à long terme. Une revue de la littérature a d’abord été effectuée afin d’identifier les facteurs de l’état nutritionnel associés au risque de complications et de mortalité après la cystectomie radicale. L’hypoalbuminémie a été identifiée comme un prédicteur potentiel de la mortalité post-opératoire. Une étude de cohorte a ensuite été menée afin d’identifier des facteurs de l’état nutritionnel associés au risque de développer des complications après cette chirurgie. Un indice de masse corporelle élevé, une baisse de l’appétit, une perte de poids, une hypo-albuminémie et une hypo-préalbuminémie avant l’opération sont les facteurs qui ont été associés au développement de complications post-opératoires. Des analyses et des études supplémentaires doivent être menées dans l’optique développer des interventions qui pourraient diminuer le risque de complications après la cystectomie radicale.

Conflit sexuel et polyandrie de la commodité chez une espèce polygynandre: les effets combinés des processus pré- et post- copulatoires sur le succès reproducteur de "Gerris buenoi"

Chez les patineurs, des processus postcopulatoires sont documentés et un conflit sexuel sur le taux d’accouplement est démontré. Cependant, leurs effets combinés sur le succès reproducteur ont rarement été investigués. Cette étude joint une analyse de filiation génétique à des observations comportementales pour évaluer l’effet des processus pré- et post- copulatoires sur le succès reproducteur de Gerris buenoi. Nos résultats montrent la nature antagoniste des combats précopulatoires et un niveau de résistance optimal intermédiaire pour les femelles. Cependant, le taux d’accouplement n’a eu aucune influence sur le succès reproducteur des deux sexes. Un taux d’accouplement élevé permettant à des processus postcopulatoires de se mettre en place ainsi que plusieurs copulations superflues ont vraisemblablement masqué les effets attendus du taux d’accouplement. Notre étude confirme l’idée que des précisions peuvent être apportées sur les forces de sélection sexuelle en jeu lorsque l’on considère tous les épisodes d’un cycle d’accouplement chez les animaux polygynandres.

Double-trouble: Negotiating Gender and Sexuality in Post-colonial Women’s Rugby in Fiji

Although women’s exclusion in sport has attracted significant attention in the western context, similar issues in relation to post-colonial societies have remained in the margins of the sociology of sport. By analysing primary, interview-based evidence, in this article we explore the challenges female rugby players face regarding gender and sexuality in Fiji; a male dominated post-colonial society. In particular, we focus on participants’ resistance to dominant cultural practices and ways in which they (re)negotiate gender norms and sexuality in a double-bind struggle against both traditional and sporting male hegemonies. We argue that the case of Fijian women rugby players illustrates an interplay between a multiplicity of power relations in sport in a post-colonial society and the resilience with which the athletes negotiate and respond to them, as well as the dynamic nature and the transformative potential of their everyday practices.

The challenge and response to global tourism in the post-modern era: the commodification, reconfiguration and mutual transformation of Habana Vieja, Cuba

There is a growing literature on the symbolic and cultural meanings of tourism and the ways in which cities are increasingly competing for tourists through the promotion of cultural assets and different forms of spectacle in the `tourist bubble'. To date, research on the role and impact of tourism in cities has largely been confined to those in Western, post-industrial economies. This paper examines the growth of cultural tourism in the central area of Havana, Cuba, and explores the range of unique, devolved, state-owned enterprises that are attempting to use tourism as a funding mechanism to achieve improvements in the social and cultural fabric of the city for the benefit of residents. The paper concludes with an assessment of the implications of this example for our understanding of how the pressures for restructuring and commodification can be moderated at the city level.
