Contemporary European migrations, civic stratification and citizenship

Since the late 1980s there has been a diversification of European migratory flows. States, which remain the key actors in migration policies despite growing European harmonisation, have responded to these complex patterns and contradictory pressures by diversifying migrant categories and statuses. The heterogeneity of migrant statuses, especially the growth in the number of those on temporary statuses and the undocumented, challenges the thesis of a post national citizenship as having been achieved in relation to non European Union or third country migrants in the European Union. The recent proposals to extend mobility and socio-economic rights to third country nationals in the EU will only apply to long-term residents with evidence of adequate resources. The inability to confront the contradictions and tensions between economic needs and political closure will lead to more repressive conditions for undocumented migrants and reinforced border controls, especially in the light of the electoral success of Far Right parties and widespread anti-immigrant attitudes in a number of European Union states.     

Actualistic research into dynamic impact and its implications for understanding differential bone fragmentation and survivorship

The relationship between bone mineral density and archaeological bone survivorship has played a critical role in zooarchaeological and taphonomic studies in recent decades. Numerous studies have suggested that higher-density skeletal element portions survive more frequently than lower-density element portions when archaeological assemblages are affected by some taphonomic processes. Interpretations of density mediated destruction have become commonplace in the archaeological literature, and are often used to explain the absence of certain bone elements and element parts in zooarchaeological assemblages. This study explores the effects of rockfall on bovid elements in varied environmental conditions and the differential survivorship of their element parts, and has implications for understanding the taphonomic processes through which bones are subjected to dynamic loading. Actualistic rockfall experiments conducted on twelve samples of frozen, fresh, and semi-dried bovid bones reveal that the generally low-density epiphyseal ends of bone elements resist fracture and analytical deletion with more frequency than the higher-density diaphyses. This evidence suggests that bone density does not correlate with likelihood of breakage or effective archaeological “destruction” when rockfall and other processes that result in dynamic impact are in action. While this research does not question the relationship between bone mineral density and the likelihood for archaeological survivorship as the result of some taphonomic processes, it presents one specific set of taphonomic processes that result in the differential survivorship of low density bone elements parts and the fragmentation and destruction of higher density element parts. This research presents evidence that shows that dynamic impact is a process capable of fragmenting and sometimes destroying high-density elements while low-density elements survive.     

Performance-Based Vulnerability Assessment of Multi-Story Reinforced Concrete Structures Exposed to Pre- and Post-Earthquake Fire

Post-earthquake fire can potentially bring about much more damage than the earthquake itself. Performing a vulnerability assessment for a structure that has already sustained damage in an earthquake and is then exposed to fire is therefore of importance. This paper describes a performance-based investigation in which applied loads to a structure are appropriately quantified. To do so, a sequential structural analysis is performed on the Life Safety performance level of a three-story reinforced concrete frame selected from a building. For the analysis to be more realistic, the slab is also included in the frame analysis through the concept of effective length. The frame is first subjected to an earthquake load with the PGA of 0.30 g followed by a fire analysis, using the ISO834 fire curve and the iBMB fire curve. The time needed for the structure weakened by the earthquake to collapse under fire is then calculated. As a benchmark, fire-only analysis is also performed for the undamaged frame. Moreover, the effect of thermal spalling is considered in the slabs. The selected frame is evaluated under various failure criteria such as load capacity, displacement, and rate of displacement. The results show that no failure is observed when the frame is exposed to fire alone, either when using the ISO curve or the iBMB curve under various failure criteria. It is also shown that while the PEF resistance based on load capacity criteria under the ISO curve is around 120 minutes, it reduces to about 95 min under the iBMB curve. However, considering the rate of deflection failure criteria, the PEF resistance is around 103 min and 75 min under the ISO and the iBMB curves, respectively. It is then concluded that in the PEF analysis, the iBMB curve is more compatible with the concept of performance-based design than the ISO curve is.

Changing Inuit Historicities in West Greenland and Nunavut

Beyond a few stereotypes framed as oppositions between written and oral, history and myth, and so on, one actually knows little about Inuit historicities. This article argues that recent changes in Inuit senses of history do not represent a progress from limited interest in historical questions to some enlightened historical consciousness. Rather, these changes should be seen as paralleling the recent rapid transitions of their societies, world views and identities. Differences between West Greenlandic and Nunavut historicities may be attributed to the fact that today’s visions of the past are the outcome of divergent historical developments within a (post‐)colonial framework.

From Hope to Escape: Post‐Soviet Russian Memory and Identity

Drawing on letters written by citizens of the USSR to US Congressman James Wright following his 1987 congressional visit and Soviet television appearance as well as follow‐up interviews conducted by this author with many of the same individuals in 2002–2004, this paper will recount the memories of several Muscovites and argue that although the western collective memory of the Cold War is one of victory, the individual accounts of Russians reveals a created memory of the Soviet past which, when confronted with the dire socioeconomic conditions that exist in post‐1991 Russia, leads to a crisis of identity.     

The Churchill–Roosevelt Bases of 1940: The Question of Heritage in their Adaptive Reuse

The US military bases in the British Western Atlantic colonies, negotiated between Churchill and Roosevelt and formalised in the 1941 Destroyers–Bases Agreement, were all abandoned by the 1990s. In the process of their reuse the question of heritage meanings arises. From existing thoughts on heritage in older military bases, the paper considers the legitimacy of recent (living memory) bases as heritage, by reference to various cases among which Malta is particularly persuasive. The Churchill–Roosevelt bases and their heritage potential are then reviewed. The paper examines the three principal naval/military bases involved, namely Argentia (Newfoundland), Bermuda and Chaguaramas (Trinidad), with respect to what heritage perspectives exist among redevelopment agencies and other concerned institutional actors. In all cases heritage constitutes a recessive if not contentious issue among the priorities of base reuse in now post‐colonial environments.     

The Groningen museum: Urban heritage in fragments

Abstract

Changes in West European cities are discussed by many writers in many different ways with the intention of questioning the aim of post‐modern theories. The new perspective has much influence on social, economic and political forms, and on activities in the city centre: Renewed views of the changes in, and the attention to, the roles that heritage plays or could play in the urban area may be helpful in finding adapted forms of post‐modern management of heritage. Heritage has many intrinsically post‐modern aspects such as its eclecticism, its non‐linearity in time and its fragmentation. To explore some post‐modern aspects of urban heritage, the three main points in the post‐modern discussion: the discussion about reproduction, hyper‐realities and legitimacy, are illustrated and examined on the basis of the Groningen Museum, a local museum built a few years, ago in a medium‐sized city in the northern Netherlands.
