Introduction: Security, Criminal Justice and Human Rights in Countering Terrorism in the Post 9/11 Era

2012

In the aftermath of the 9/11 attacks on New York and Washington, many commentators claimed that the world had changed ‘forever’ with international terrorism constituting one of the defining global security challenges of the twenty-first century. The renewed focus on counter-terrorism law and policy also called into question whether the lessons drawn from previous terrorism emergencies are pertinent to the post-9/11 environment. Indeed, to what extent, if at all, are the principles identified for the liberal democratic response to traditional forms of terrorism applicable to a response to contemporary international terrorism? The historical, political and security implications of 9/11 notwit…

Conoscere per deliberare. Tucidide II 40,2

2022

Nel passo tucidideo esaminato si difende la lezione οἱ αὐτοί attraverso il raffronto con testi greci finora non considerati nel dibattito critico, e soprattutto alla luce della visione non elitista della democrazia quale emerge nell’Epitafio di Pericle. In the passage examined οἱ αὐτοί is defended by comparing it with Greek texts so far not considered in the critical debate, and especially in light of the non-elitist idea of democracy as it emerges in Pericles' Epitaphius.

Effects of fiber orientation of adjacent plies on the mode I crack propagation in a carbon-epoxy laminates

2011

Abstract The influence of ply orientation on the resistance to mode I delamination of multidirectional composite laminates can be assessed by Double Cantilever Beam (DCB) tests. However, one of the difficulties associated with such a study is the change in overall elastic parameters occurring when modifying local ply orientations. The present work uses laminates with special stacking sequences allowing for isolating the orientation parameter. Multidirectional DCB specimens were designed so as to obtain an uncoupled quasi isotropic and quasi-homogeneous elastic behavior, with the same properties for the entire laminate and the two sub laminates separated by the pre crack at mid-plane. The re…

Evaluation of toughness by finite fracture mechanics from crack onset strain of brittle coatings on polymers

2008

Crack onset strain measurements of a confined layer in tension provide the means for layer toughness estimation. The procedure can be simplified if steady-state conditions prevail starting from the commencement of crack propagation, an assumption frequently employed in energy release rate evaluation. It is demonstrated, by numerical analysis of experimental data, that an estimate of the defect size in the film is needed in order to reliably evaluate its fracture toughness from the crack onset strain. Only if microcracks of sufficient size are present in the brittle layer, the steady-state energy release rate at the crack onset strain can be identified with layer toughness. Otherwise, the to…

Desclasamientoy desencanto. La representación de las clases medias como eje de una relectura generacional de la transición española

2014

Resumen: A partir de un ejemplo de cultura underground de mediados de los años setenta, este texto reflexiona sobre los límites de las narrativas convencionales y críticas sobre la instauración de la democracia en España debido a su sesgo politológico y plantea la existencia de un metarrelato sociológico subyacente común. Su fundamento es una representación de la clase media como estrato social que suaviza el conflicto social y garantiza la modernización económica y política. El artículo desvela una parte del proceso de cristalización, a partir de legados anteriores, de un discurso mesocrático en la cultura española durante la dictadura franquista, al que contribuyeron al unísono intelectua…

International solidarity in the GDR and transnationality: an analysis of primary school materials for Namibian child refugees

2014

As part of a solidarity project between the South West African People’s Organization (SWAPO) and the German Democratic Republic (GDR), approximately 430 Namibian children were brought to the GDR from 1979 to 1989 to be trained as an elite for a future liberated Namibia. The children attended school in the GDR until they were brought back to Namibia in August 1990. The school lessons intertwined topics about Namibia and SWAPO with the usual GDR school curriculum. The linchpin of this intertwining was the socialist ideal of international solidarity. This article uses an objective-hermeneutic analysis to show how the school materials produced transnationality.

Statistical model of the transverse ply cracking in cross-ply laminates by strength and fracture toughness based failure criteria

2008

Cross-ply laminate subjected to tensile loading provides a relatively well understood and widely used model system for studying progressive cracking of the transverse ply. This test allows to identify material strength and/or toughness characteristics as well as to establish relation between damage level and the composite stiffness reduction. The transverse ply cracking is an inherently stochastic process due to the random variability of local material properties of the plies. The variability affects both crack initiation (governed by the local strength) and propagation (governed by the local fracture toughness). The primary aim of the present study is elucidation of the relative importance…

Entryism in the British Labour Party, 1920- 1992

2022

This work aims at studying entryism in the context of the revolutionary socialist left in Britain, from the inception of the Communist Party of Great Britain in 1920 to the departure of Militant, the largest entryist organisation of the Kingdom, from the Labour Party in 1992.Entryism, which is often at the heart of political myths, is a tactic of penetration of a political party by another, aiming at accomplishing objectives, the nature of which can change depending on the type of entry. The intention of this study is to show to what extent there is not one type of entryism but several ones.The adopted methodology is chronological. The first part is dedicated to the relationship between the…

A computational framework for coating fatigue analysis of wind turbine blades due to rain erosion

2021

Author's accepted manuscript The rain-induced fatigue damage in the wind turbine blade coating has attracted increasing attention owing to significant repair and maintenance costs. The present paper develops an improved computational framework for analyzing the wind turbine blade coating fatigue induced by rain erosion. The paper first presents an extended stochastic rain field simulation model that considers different raindrop shapes (spherical, flat, and spindle), raindrop sizes, impact angles, and impact speeds. The influence of these raindrop characteristics on the impact stress of the blade coating is investigated by a smoothed particle hydrodynamics approach. To address the expensive …
