We argue that attitudes about immigration can be better understood by paying closer attention to the various ways in which national group boundaries are demarcated. We describe two related lines of work that address this. The first deals with national group definitions and, based on evidence from studies carried out in England and analyses of international survey data, argues that the relationship between national identification and prejudice toward immigrants is contingent on the extent to which ethnic or civic definitions of nationality are endorsed. The second, which uses European survey data, examines support for ascribed and acquired criteria that can be applied when determining who is permitted to migrate to one's country, and the various forms of national and individual threat that affect support for these criteria. We explain how the research benefits from a multilevel approach and also suggest how these findings relate to some current policy debates.

The study sought to contextualize the physical, social and emotional adjustments that are faced by oesophageal cancer patients following surgery. Semi-structured interviews were conducted with five survivors, guided by the principles of Interpretative Phenomenological Analysis (IPA). Participants’ accounts encompassed descriptions of personal, social and medical relationships, illness and treatment experiences, eating behaviours, and spiritual and religious perspectives, representing myriad challenges to the self-concept. Surviving patients may have a role in addressing patient expectations about eating. The importance of attempts to nurture and maintain a sense of self should be recognized by those providing care.

Advanced glycation endproducts (AGEs) are derivatives of nonenzymatic reactions between sugars and protein or lipids, and together with AGE-specific receptors are involved in numerous pathogenic processes associated with aging and hyperglycemia. Two of the known AGE-binding proteins isolated from rat liver membranes, p60 and p90, have been partially sequenced. We now report that the N-terminal sequence of p60 exhibits 95% identity to OST-48, a 48-kDa member of the oligosaccharyltransferase complex found in microsomal membranes, while sequence analysis of p90 revealed 73% and 85% identity to the N-terminal and internal sequences, respectively, of human 80K-H, a 80- to 87-kDa protein substrate for protein kinase C. AGE-ligand and Western analyses of purified oligosaccharyltransferase complex, enriched rough endoplasmic reticulum, smooth endoplasmic reticulum, and plasma membranes from rat liver or RAW 264.7 macrophages yielded a single protein of approximately 50 kDa recognized by both anti-p60 and anti-OST-48 antibodies, and also exhibited AGE-specific binding. Immunoprecipitated OST-48 from rat rough endoplasmic reticulum fractions exhibited both AGE binding and immunoreactivity to an anti-p60 antibody. Immune IgG raised to recombinant OST-48 and 80K-H inhibited binding of AGE-bovine serum albumin to cell membranes in a dose-dependent manner. Immunostaining and flow cytometry demonstrated the surface expression of OST-48 and 80K-H on numerous cell types and tissues, including mononuclear, endothelial, renal, and brain neuronal and glial cells. We conclude that the AGE receptor components p60 and p90 are identical to OST-48, and 80K-H, respectively, and that they together contribute to the processing of AGEs from extra- and intracellular compartments and in the cellular responses associated with these pathogenic substances.

In this paper, we present a novel approach to person verification by fusing face and lip features. Specifically, the face is modeled by the discriminative common vector and the discrete wavelet transform. Our lip features are simple geometric features based on a lip contour, which can be interpreted as multiple spatial widths and heights from a center of mass. In order to combine these features, we consider two simple fusion strategies: data fusion before training and score fusion after training, working with two different face databases. Fusing them together boosts the performance to achieve an equal error rate as low as 0.4% and 0.28%, respectively, confirming that our approach of fusing lips and face is effective and promising.

Two semianalytical relations [Nature, 1996, 381, 137 and Phys. Rev. Lett. 2001, 87, 245901] predicting dynamical coefficients of simple liquids on the basis of structural properties have been tested by extensive molecular dynamics simulations for an idealized 2:1 model molten salt. In agreement with previous simulation studies, our results support the validity of the relation expressing the self-diffusion coefficient as a Function of the radial distribution functions for all thermodynamic conditions such that the system is in the ionic (ie., fully dissociated) liquid state. Deviations are apparent for high-density samples in the amorphous state and in the low-density, low-temperature range, when ions condense into AB(2) molecules. A similar relation predicting the ionic conductivity is only partially validated by our data. The simulation results, covering 210 distinct thermodynamic states, represent an extended database to tune and validate semianalytical theories of dynamical properties and provide a baseline for the interpretation of properties of more complex systems such as the room-temperature ionic liquids.

Based upon the original application to the European Commission, this article gives insights into the thinking of the Euroidentities team at the point that the project began. The question: “Is the European ‘identity project’ failing?” is posed in the sense that the political and economic attainments of the European Union have not been translated into a sense of identity with or commitment to Europe from the populaces that have benefited from them. The urgency of European ‘identity work’ is asserted with a number of levels for the construction of European identity being hypothesized. Euroidentities is intended to break conceptual ground by bringing together on an equal footing two apparently antagonistic views of identity -- the collective and institutional and the individual and biographical – to give a more anchored and nuanced view of identity formation and transformation than either can provide on its own. Rather than following the dominant approaches to research on European identity that have been macro-theoretical and ‘top-down’, retrospective in-depth qualitative biographical interviews are planned since they provide the ideal means of gaining insight into the formation of a European identity or multiple identities from the ‘bottom up’ perspective of non-elite groups. The reliability of analysis will be buttressed by the use of contrastive comparison between cases, culminating in contrastive comparison across the national project teams between cases drawn from different ‘sensitized groups’ that provide the fieldwork structure of the project. The paper concludes with a summary of some of the more significant findings.

Relatively little research has examined the relations between growing up in a community with a history of protracted violent political conflict and subsequent generations' well-being. The current article examines relations between mothers' self-report of the impact that the historical political violence in Northern Ireland (known, as the Troubles) has on her and her child's current mental health. These relations are framed within the social identity model of stress, which provides a framework for understanding coping responses within societies that have experienced intergroup conflict. Mother-child dyads (N = 695) living in Belfast completed interviews. Results suggest that the mother-reported impact of the Troubles continue to be associated with mothers' mental health, which, in, turn, is associated with her child's adjustment. The strength of mothers' social identity moderated pathways between the impact of the Troubles and her mental health, consistent with the social identity model of stress.

One of the enduring illusions about Northern Ireland is that its society can be conceptualized through a binary distinction between protestant and catholic. unionist and nationalist. It is increasingly apparent that these broad domains are themselves fractured and diverse and that otherness is often conceived from within rather than without. Northern Ireland can also be viewed as a laboratory for identity formation as unionists and loyalists strive to reconcile themselves with the fundamental political changes that have followed in the wake of the Peace Process. This paper considers one aspect of the contestation of belonging that increasingly characterizes unionism. It examines the competition for the ownership of the mythology of the Battle of the Somme ( 1916), long a key event in the unionist narrative. In particular, the paper addresses the ways in which paramilitary organizations are using the Somme to legitimate their own activities but also to distance the loyalist working classes from the former hegemonic Britishness of official unionism and the sectarianism of the Orange Order. The analysis concludes that loyalist identity is being conceptualized thorough a narrative of betrayal from within and at an intensely localized scale.
