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.

Genetic factors associated with intestinal metaplasia in a high risk Singapore-Chinese population: a cohort study

Background: Intestinal metaplasia (IM) is an important precursor lesion in the development of gastric cancer ( GC). The aim of this study was to investigate genetic factors previously linked to GC risk for their possible association with IM. A total of 18 polymorphisms in 14 candidate genes were evaluated in a Singapore-Chinese population at high risk of developing GC.

Modelling distributional trends to inform conservation strategies for endangered species

Aim: Species loss has increased significantly over the last 1000 years and is ultimately attributed to the direct and indirect consequences of increased human population growth across the planet. A growing number of species are becoming endangered and require human intervention to prevent their local extirpation or complete extinction. Management strategies aimed at mitigating a species loss can benefit greatly from empirical approaches that indicate the rate of decline of a species providing objective information on the need for immediate conservation actions, e.g. captive breeding; however, this is rarely employed. The current study used a novel method to examine the distributional trends of a model endangered species, the freshwater pearl mussel, Margaritifera margaritifera (L.).
Location: United Kingdom and Republic of Ireland.
Methods: Using species presence data within 10-km grid squares since records began three-parameter logistic regression curves were fitted to extrapolate an estimated date of regional extinction.
Results: This study has shown that freshwater pearl mussel distribution has contracted since known historical records and outlier populations were lost first. Within the United Kingdom and Republic of Ireland, distribution loss has been greatest in Scotland, Northern Ireland, Wales and England, respectively, with the Republic of Ireland containing the highest relative proportion of M. margaritifera distribution, in 1998.
Main conclusions: This study provides empirical evidence that this species could become extinct throughout countries within the United Kingdom within 170 years under the current trends and emphasizes that regionally specific management strategies need to be implemented to prevent extirpation of this species.
