Whiteness and loss in outer East London: tracing the collective memories of diaspora space

This paper explores collective memory in Newham, East London. It addresses how remembering East London as the home of whiteness and traditional forms of community entails powerful forms of forgetting. Newham's formation through migration – its ‘great time’ – has ensured that myths of indigeneity and whiteness have never stood still. Through engaging with young people's and youth workers' memory practices, the paper explores how phantasms of whiteness and class loss are traced over, and how this tracing reveals ambivalence and porosity, at the same time as it highlights the continued allure of race. It explores how whiteness and class loss are appropriated across ethnic boundaries and how they are mobilized to produce new forms of racial hierarchy in a ‘super-diverse’ place

Inactivation of RNA Viruses by Gamma Irradiation: A Study on Mitigating Factors

Effective inactivation of biosafety level 4 (BSL-4) pathogens is vital in order to study these agents safely. Gamma irradiation is a commonly used method for the inactivation of BSL-4 viruses, which among other advantages, facilitates the study of inactivated yet morphologically intact virions. The reported values for susceptibility of viruses to inactivation by gamma irradiation are sometimes inconsistent, likely due to differences in experimental protocols. We analyzed the effects of common sample attributes on the inactivation of a recombinant vesicular stomatitis virus expressing the Zaire ebolavirus glycoprotein and green fluorescent protein. Using this surrogate virus, we found that sample volume and protein content of the sample modulated viral inactivation by gamma irradiation but that air volume within the sample container and the addition of external disinfectant surrounding the sample did not. These data identify several factors which alter viral susceptibility to inactivation and highlight the usefulness of lower biosafety level surrogate viruses for such studies. Our results underscore the need to validate inactivation protocols of BSL-4 pathogens using “worst-case scenario” procedures to ensure complete sample inactivation

Theorising noncitizenship: concepts, debates and challenges

Existing political theory, particularly which deals with justice and/or rights, has long assumed citizenship as a core concept. Noncitizenship, if it is considered at all, is generally defined merely as the negation or deprivation of citizenship. As such, it is difficult to examine successfully the status of noncitizens, obligations towards them, and the nature of their role in political systems. This article addresses this critical gap by defining the theoretical problem that noncitizenship presents and demonstrating why it is an urgent concern. It surveys the contributions to the special issue for which the article is an introduction, drawing on cross-cutting themes and debates to highlight the importance of theorising noncitizenship due to both the problematic gap that exists in the theoretical literature, and the real world problems created as a result of noncitizenship which are not currently successfully addressed. Finally, the article discusses key future directions for the theorisation of noncitizenship
