This paper begins by describing the moral panics that have tended to emerge sporadically in Northern Ireland over the last few years with regard to young people’s involvement in sectarian violence in Belfast. Within this, while these young people have been cast in the traditional role of folk devils, the paper will show how younger children also tend to be explicitly identified and named in an ambiguous way through such moral panics; playing a deviant role as participators, and sometimes instigators, of sectarian violence but also carrying the symbolic responsibility of representing Belfast’s future. It will be shown that it is because of this ambiguous position that it is adults rather than the children themselves that tend to be held responsible for their actions; either as rioters using the children as political pawns or as parents guilty of neglect. With this as a starting point the paper then explores the perspectives and experiences of two groups of 10-11 year old children living in Belfast and the impact of these moral panics on them. One group of children, living in affluent middle class areas were found to be appropriating and re-working these broader moral panics into more general discourses of derision that tended to pathologize working class children and communities more generally. For the other group of children, living in economically deprived areas with high levels of sectarian tensions and violence, their experiences of such violence and their participation in it are discussed. It will be shown that for these children, the broader moral panics that exist tend to have the effect of reinforcing the processes that tend to segregate and exclude them.

Opacity is a property of many plasmas. It is normally expected that if an emission line in a plasma becomes optically thick, then its intensity ratio to that of another transition that remains optically thin should decrease. However, radiative transfer calculations undertaken both by ourselves and others predict that under certain conditions the intensity ratio of an optically thick to an optically thin line can show an increase over the optically thin value, indicating an enhancement in the former. These conditions include the geometry of the emitting plasma and its orientation to the observer. A similar effect can take place between lines of differing optical depths. While previous observational studies have focused on stellar point sources, here we investigate the spatially resolved solar atmosphere using measurements of the I(1032 Å)/I(1038 Å) intensity ratio of O VI in several regions obtained with the Solar Ultraviolet Measurements of Emitted Radiation instrument on board the Solar and Heliospheric Observatory satellite. We find several I(1032 Å)/I(1038 Å) ratios observed on the disk to be significantly larger than the optically thin value of 2.0, providing the first detection (to our knowledge) of intensity enhancement in the ratio arising from opacity effects in the solar atmosphere. The agreement between observation and theory is excellent and confirms that the O VI emission originates from a slab-like geometry in the solar atmosphere, rather than from cylindrical structures.

Learning has an important position in the development of employees and their expertise. This article focuses on the role and utilization of intra and interorganizational formal and informal learning within different types of learning networks. Specifically, we investigate different types of networks (inter- or intraorganizational) and different types of learning (formal or informal) that can occur within such networks. Our qualitative case study is based on 46 expert interviews involving 49 interviewees, through which we explore how formal and informal learning was used in the development and implementation of quality improvement initiatives at a large public teaching hospital in Portugal. Our analysis suggests that formal and informal learning can take place within different types of learning networks that draw on internal resources as well as on the collaboration with external entities. The article argues that it is important for HRD managers, seeking to support organizational learning, to understand how different types of learning take place, and which features of learning networks support these processes.

This study compares the internal dynamics of religious change in the 'post-evangelical' Ikon community in Belfast, Northern Ireland, and a charismatic, multiethnic congregation in Harare, Zimbabwe. Although the theological ideas behind Ikon and the congregation vary widely, the processes whereby both groups manage change are broadly similar and have wider theoretical significance. Accordingly, this article analyses how people use the religious resources of their traditions to construct 'havens' in which change is facilitated. Havens are conceived of as safe spaces where people use religious resources to challenge ethnic boundaries and power structures. They can be seen to function as mechanisms for disrupting long-entrenched feedback patterns of opposition and conflict. © 2010 The Editor of Ethnopolitics.

On the basis of the technique of time reversal (TR), through adding dispersive delay lines to each element of a TR mirror, a method for low contrast tumour detection is proposed. When compared with a conventional detection method, the proposed method improves refocusing onto a low dielectric contrast tumour. The method does not require an accurate estimate of the position of the tumour. The theoretical basis for the approach is given and numerical simulated results demonstrate the capability of the proposed method.

Since 2012, refugee protest camps and occupations have been established throughout Europe that contest the exclusion of refugees and asylum seekers, but that also make concrete demands for better living conditions and basic rights. It is a movement that is led by migrants as noncitizens, and so reveals new ways of thinking of the political agency and status of noncitizenship not as simply reactive to an absence of citizenship, but as a powerful and transgressive subjectivity in its own right. This paper argues that we should resist collapsing analysis back into the frameworks of citizenship, and instead be attentive to the politics of presence and solidarity manifest in these protest camps as a way of understanding, and engaging, noncitizen activism.
