Cold War Along the Emerald Curtain: Rural Boundaries in a Contested Border Zone

This paper examines how anxieties about ethnic identity proliferate as state borders begin to shift and open in response to accelerating possibilities of cross-border cooperation. As the border becomes more porous, social and cultural boundaries become marked in other ways, spatially re-scaled to reflect new uncertainties consequent upon border change. Using an example from the Irish land border, the paper traces how national space is re-imagined and re-placed in the everyday practices of residents in a violent border zone from which the state is ostensibly retreating. It shows that communal division is as sharply drawn as ever at a time when the ‘visibility’ of the state border itself is beginning to diminish.

What Did the Lawyers Do During the 'War' ? Neutrality, Conflcit and the Culture of Quietism

Using Northern Ireland as a case study, this paper explores how lawyers responded to the challenges of entrenched discrimination, sustained political violence and an emerging peace process. Drawing upon the literature of the sociology of lawyering, it examines whether lawyers can or should be more than ‘paid technicians’ in such circumstances. It focuses in particular upon a number of ‘critical junctures’ in the legal history of the jurisdiction and uncouples key elements of the local legal culture which contributed to an ethos of quietism. The paper argues that the version of legal professionalism that emerged in Northern Ireland was contingent and socially constructed and, with notable exceptions, obfuscated a collective failure of moral courage. It concludes that facing the truth concerning past silence is fundamental to a properly embedded rule of law and a more grounded notion of what it means to be a lawyer in a conflict.

Representing War as Punishment in the War on Terror

This paper shows how the notion of punishment has been invoked by former US President George W. Bush, and ex UK Prime Minister Tony Blair to represent war. It is suggested that in this context, the notion of punishment serves different objectives: legitimizing violence, suggesting the sovereign role taken by the US and highlighting the emergence of new sensibilities. Building on previous literature in criminology and international relations it examines points of contact between two previously distinct security mechanisms - war and punishment- and suggests possible effects of this discursive blurring. It highlights not only the need for criminologists to engage with international relations literature but also the need to evaluate closely the different nature of the international context.

Monoclonal antibody development for acrylamide-adducted human haemoglobin; A biomarker of dietary acrylamide exposure

The spontaneous formation of the neurotoxic carcinogen acrylamide in a wide range of cooked foods has recently been discovered, leading to dietary exposure estimates of 30.8 mu g of acrylamide day(-1) for an average 77 kg human male. This is considerably higher than the European legal limit of acrylamide in drinking water, which is approximately 0.2 mu g of acrylamide person(-1) day(-1). A recent study of 62,573 women over 11.3 years has observed an increased risk of postmenopausal endometrial and ovarian cancer (but not breast cancer) with increasing dietary acrylamide intake, demonstrating significant risk to human health. As individual acrylamide exposure is affected by dietary habits, cooking methods, and cigarette consumption; accurate extrapolation from estimated dietary exposure is extremely difficult. Quantifying biomarkers of acrylamide exposure therefore remains the most effective means of rapidly determining individual exposure to acrylamide, and correlating exposure with lifestyle choices. Current methodologies for the analysis of blood biomarkers of acrylamide are focused on expensive, slower chromatographic techniques such as GC and LC coupled to mass spectrometry. This paper describes the first successful development of two monoclonal antibodies specific to acrylamide-adducted haemoglobin (IC50 of 94 ng ml(-1) and 198 ng ml(-1)), that are suitable for use in a high-throughput biomarker immunoassay to determine individual acrylamide exposure. Further development of acrylamide-haemoglobin standards with defined levels of acrylamide adduction will enable a fully quantitative assay, and allow sensitivity comparisons with alternative chromatographic methods of analysis.

War, peace and suicide: The case of Northern Ireland

Durkheim’s idea that war reduces suicide through greater social and political integration has been used to explain suicide trends during the Northern Ireland conflict and in the period of peace. The applicability of Durkheim is critically evaluated through a case study of suicide trends by age, gender and cause of death over a forty year period. The key finding is that the cohort of children and young people who grew up in the worst years of violence during the 1970s, have the highest and most rapidly increasing suicide rates, and account for the steep upward trend in suicide following the 1998 Agreement. Contrary to Durkheim, the recent rise in suicide involves a complex of social and psychological factors. These include the growth in social isolation, poor mental health arising from the experience of conflict, and the greater political stability of the past decade. The transition to peace means that externalised aggression is no longer socially approved. It becomes internalised instead.

Out-of-field cell survival following exposure to intensity-modulated radiation fields

PURPOSE:
To determine the in-field and out-of-field cell survival of cells irradiated with either primary field or scattered radiation in the presence and absence of intercellular communication.
METHODS AND MATERIALS:
Cell survival was determined by clonogenic assay in human prostate cancer (DU145) and primary fibroblast (AGO1552) cells following exposure to different field configurations delivered using a 6-MV photon beam produced with a Varian linear accelerator.
RESULTS:
Nonuniform dose distributions were delivered using a multileaf collimator (MLC) in which half of the cell population was shielded. Clonogenic survival in the shielded region was significantly lower than that predicted from the linear quadratic model. In both cell lines, the out-of-field responses appeared to saturate at 40%-50% survival at a scattered dose of 0.70 Gy in DU-145 cells and 0.24 Gy in AGO1522 cells. There was an approximately eightfold difference in the initial slopes of the out-of-field response compared with the a-component of the uniform field response. In contrast, cells in the exposed part of the field showed increased survival. These observations were abrogated by direct physical inhibition of cellular communication and by the addition of the inducible nitric oxide synthase inhibitor aminoguanidine known to inhibit intercellular bystander effects. Additional studies showed the proportion of cells irradiated and dose delivered to the shielded and exposed regions of the field to impact on response.
CONCLUSIONS:
These data demonstrate out-of-field effects as important determinants of cell survival following exposure to modulated irradiation fields with cellular communication between differentially irradiated cell populations playing an important role. Validation of these observations in additional cell models may facilitate the refinement of existing radiobiological models and the observations considered important determinants of cell survival.
