Detention-as-spectacle

Using a combination of migration studies, political sociology, and policy studies, this paper explores the contradictions and violence of immigration detention, its architectures, and its audiences. The concept of “detention-as-spectacle” is developed to make sense of detention’s hypervisible and obscured manifestations in the European Union. We focus particularly on two case studies, the United Kingdom and Malta, which occupy different geopolitical positions within the EU. Detention-as-spectacle demonstrates that detention is less related to deterrence and security than to displaying sovereign enforcement, control, and power. A central aspect of the sovereign spectacle is detention’s purported ability to order and even halt “crises” of irregular immigration, while simultaneously creating and reinforcing these crises. The paper concludes by examining recent disruptions to the spectacle, and their implications

A systematic review exploring variables related to bystander intervention in sexual violence contexts

This article presents a systematic review of the available literature which has investigated the role of key variables in facilitating or inhibiting bystander intervention (including direct intervention, tertiary and secondary prevention) in sexual violence (SV) contexts. Studies exploring the role of individual, situational and contextual variables were grouped to provide a narrative overview of bystanders’ personal characteristics as well as the immediate and wider contexts which may be influencing their bystander behaviour. A systematic search of published literature from four electronic databases identified 2526 articles that were screened, of which 85 studies met the inclusion criteria. Most studies focused upon the role of individual variables, in particular gender of bystander. This body of work finds females are more likely to intervene than males; however, not all studies report these differences and in some cases, this is influenced by the type of intervention behaviour being considered. Regarding situational variables, the most commonly researched variable was the presence of other bystanders, although the role of this variable as inhibiting or facilitating was not clear. Finally, the most commonly researched contextual variable was social norms towards intervention, which has consistently shown greater bystander intervention when there is a belief that peers support such behaviour. Very few studies considered the interaction between these variables. Therefore, it is important for future research to consider this gap in the literature so that we can obtain a more well-rounded understanding of variables that can inhibit and facilitate bystander intervention in SV contexts

Facilitators and barriers of bystander intervention: A focus group study with a university sample

Image-based sexual abuse (IBSA) encompasses the taking, sharing, and/or threatening to share nude or sexual images of others without their consent. The prevalence of IBSA is growing rapidly due to technological advancements, such as access to smartphones, that have made engagement in such activities easier. Bystanders offer an important means of intervention, but little is known about what facilitates or inhibits bystander action in these contexts. To address this gap in the literature, seven focus groups (n = 35) were conducted to explore the factors that facilitate and inhibit bystander action in the context of three different IBSA scenarios (taking, sharing, and making threats to share nude or sexual images without consent). Using thematic analysis, eight themes were identified, suggesting that the perceived likelihood of intervention increased with greater feelings of responsibility, empathy with the victim, reduced feelings of audience inhibition, greater feelings of safety, greater anger toward the IBSA behavior, closer relationships with the victim and perpetrator, the incident involving a female victim and male perpetrator, and perception of greater benefits of police involvement. These findings are considered alongside the physical sexual violence literature in highlighting the similarities and nuances across the different contexts. Implications for the development of policies and educational materials are discussed in relation to encouraging greater bystander intervention in IBSA contexts

The human CTF4-orthologue AND-1 interacts with DNA polymerase α/primase via its unique C-terminal HMG box

A dynamic multi-protein assembly known as the replisome is responsible for DNA synthesis in eukaryotic cells. In yeast, the hub protein Ctf4 bridges DNA helicase and DNA polymerase and recruits factors with roles in metabolic processes coupled to DNA replication. An important question in DNA replication is the extent to which the molecular architecture of the replisome is conserved between yeast and higher eukaryotes. Here we describe the biochemical basis for the interaction of the human CTF4-orthologue AND-1 with Pol α/primase, the replicative polymerase that initiates DNA synthesis. AND-1 has maintained the trimeric structure of yeast Ctf4, driven by its conserved SepB domain. However, the primary interaction of AND-1 with Pol α/primase is mediated by its C-terminal HMG box, unique to mammalian AND-1, which binds the B subunit, at the same site targeted by the SV40 T antigen for viral replication. In addition, we report a novel DNA-binding activity in AND-1, which might promote the correct positioning of Pol α/primase on the lagging-strand template at the replication fork. Our findings provide a biochemical basis for the specific interaction between two critical components of the human replisome, and indicate that important principles of replisome architecture have changed significantly in evolution.This work was supported by a Wellcome Trust investigator award to L.P.

The secret empire of signals intelligence : GCHQ and the persistence of the colonial presence

Why did Britain remove the population of an idyllic Indian Ocean archipelago? Why has Britain resisted granting citizenship to the inhabitants of another small island in the mid-Atlantic? Why does Britain still ‘own’ 90 square miles of Cyprus? The answer, we suggest, lies in part with the heritage of Bletchley Park, an obsession with informational dominance in world politics that demands the control of key nodes in international telecommunications around the globe. We also argue that intelligence studies have focused unduly on the human agent or the secret policeman and as a result, the issue of electronic imperialism has been a neglected aspect of intelligence collection across the Global South. Here we focus on Britain’s Government Communications Headquarters (GCHQ) and suggest that computers, colonies and ocean cables enjoy strange and unexpected connections that can alter the fate of small nations. We conclude that perhaps geographers, rather than historians or political scientists, deploy the most advanced conceptual tools for examining this phenomenon

A Vehicle for Research: Using Street Sweepers to Explore the Landscape of Environmental Community Action

Researchers are developing mobile sensing platforms to facilitate public awareness of environmental conditions. However, turning such awareness into practical community action and political change requires more than just collecting and presenting data. To inform research on mobile environmental sensing, we conducted design fieldwork with government, private, and public interest stakeholders. In parallel, we built an environmental air quality sensing system and deployed it on street sweeping vehicles in a major U.S. city; this served as a "research vehicle" by grounding our interviews and affording us status as environmental action researchers. In this paper, we present a qualitative analysis of the landscape of environmental action, focusing on insights that will help researchers frame meaningful technological interventions.Comment: 10 page

Correlated evolution of nest and egg characteristics in birds

Correlational selection is defined as selection for adaptive character combinations, and it therefore favours combinations of coevolved traits via phenotypic integration. Whereas the evolution of avian nest-building and egg-laying characteristics are well understood, their correlated dynamics remain overlooked. Here, we examined patterns of correlated evolution between nest, egg and clutch characteristics in 855 species of birds from 90 families, representing nearly 9% and 33% of avian species- and family-level diversity. We show that the ancestral state of birds’ nests was semi-open with nest sites having since become progressively more open over time. Furthermore, nest characteristics appear to have influenced egg-laying patterns in that while semi-open nests with variable clutch sizes were probably ancestral, clutch sizes have declined over evolutionary time in both open and closed nests. Ancestrally, avian eggs were also large, heavy and either elliptic or round, and there have been high transition rates from elliptic to round eggs in open nests and vice versa in closed nests. Ancestrally, both unpigmented (white) and pigmented (blue–brown) eggs were laid in open nests, although blue–brown eggs have transitioned more to white over time in open and closed nests, independently. We conclude that there has been a remarkable level of correlated evolution between the nest and egg characteristics of birds, which supports scenarios of correlational selection on both of these extended avian phenotypes

A Derivation of Three-Dimensional Inertial Transformations

The derivation of the transformations between inertial frames made by Mansouri and Sexl is generalised to three dimensions for an arbitrary direction of the velocity. Assuming lenght contraction and time dilation to have their relativistic values, a set of transformations kinematically equivalent to special relativity is obtained. The ``clock hypothesis'' allows the derivation to be extended to accelerated systems. A theory of inertial transformations maintaining an absolute simultaneity is shown to be the only one logically consistent with accelerated movements. Algebraic properties of these transformations are discussed. Keywords: special relativity, synchronization, one-way velocity of light, ether, clock hypothesis.Comment: 16 pages (A5), Latex, one figure, to be published in Found. Phys. Lett. (1997
