Successive substance misuse strategies in Northern Ireland and elsewhere have
been underpinned by the goal of minimising the harm accruing from the use of alcohol and other drugs. However, what it means for a person’s alcohol use to cause harm is an evolving concept. As the understanding of harm changes, the type of evidence needed to estimate the scale of harm and to evaluate the success of a given initiative changes also.
This paper does three things. We first highlight a recent model by Laslett and
colleagues for estimating the harm of one individual’s alcohol use to other individuals, the centrepiece of a report to the Alcohol Education and Research Foundation (AERF) in 2010. This model has been hugely influential in identifying areas where harms from alcohol use accrue and in attempting to quantify those harms (e.g. the cost of injuries inflicted during intoxication). We suggest three ways in which this model could be improved by accounting for: (a) the influence of one individual’s drinking on the drinking behaviour of their peers; (b) the level of use which triggers a given harm; and (c) the degree of time-lag in each of
the domains of harm.
Secondly, we explore specific challenges to developing effective policy on
adolescents’ drinking behaviours, drawing on research which specifically elicits the perspectives of young people on why they drink.
Thirdly, we examine the relative harms of allowing moderate levels of drinking
among mid-adolescents versus promoting zero use up until late adolescence.

In many advanced democracies, political scientists have lamented the rise of professional politicians as a challenge to the effective representation of diverse electorates. In contrast, their relative absence from Canadian federal politics gives rise to concerns over high levels of political amateurism among Canadian MPs. This study, thus, seeks to account for the numerical weakness of individuals with an occupational background in politics in the Canadian Parliament. It utilizes both individual-level quantitative data on MPs serving between the 35th and 41st Parliaments, inclusive, as well as material from qualitative interviews with over seventy former MPs. Conceptualizing the field of politics as a career in itself, and drawing on career development theory, the study finds that at the key stages of establishing, maintaining, and disengaging from a federal political career, there are specific challenges that are not significantly ameliorated by the possession of professional experience in politics itself. Professional politicians, therefore, have no major advantage over those with non-political occupational backgrounds in their career development. Furthermore, by acknowledging the existence of different types of professional politician, it finds that those whose primary occupational background was in politics itself to be in a distinct minority, but the extent of political amateurism is challenged by a much larger minority of MPs whose primary occupation was non-political but who still possess some secondary or electoral experience prior to entering Parliament.

Archaeological excavation has provided an alternative source of evidence for the development of the late medieval peasant house. It is argued that whilst there was a significant change in building techniques in the decades around 1200 with the adoption of ground-set timbers, the most important factor which led to the survival of houses was a fall in real wages during the thirteenth century. This encouraged peasants to repair existing buildings, rather than replace them with new ones. Alternative traditions of building are also investigated. Stone construction was adopted in a number of areas of England, but in spite of the durability of the material, few medieval peasant buildings of this type have survived in use because of the failure to use lime mortar. Decisions about whether to invest in a building’s renovation will depend on the capital initially expended upon it. This interpretation is considered against the data from the fifteenth century and found to conform satisfactorily. Its implications are considered for the period between 1200 and 1350. Data collected from archaeological excavations combined with the results of dendrochronology on a growing number of closely dated standing buildings suggest that there was a significant ‘cull’ of houses in the period after 1350 as new dwellings were constructed.

Purpose: Researchers have demonstrated associations between trauma and psychosis. Childhood trauma, in particular, appears to be an important determinant. Recently, bullying has become considered a traumatic experience in its own right. This review aims to analyse research with prospective designs, which will enable conclusions about whether or not bullying causes psychosis.
Methods: A systematic review of the literature was carried out independently by two reviewers. Eligibility and quality assessment criteria were applied. A meta-analysis and narrative synthesis were then completed.
Results: Ten studies met inclusion criteria. Four used data from the same large database, and were combined as one. The majority provided confirmation that bullying appears to cause later development of psychosis. A meta-analysis yielded an unadjusted odds ratio (OR) of 2.148 [95% confidence interval (CI) 1.140–4.044].
Conclusions: The studies reviewed here suggest that bullying does predict the later development of psychotic symptoms. What is lacking from the literature is adequate investigation into other potential mediating factors. The current review highlights the significant role of bullying within this complex interaction. Potential mediating variables are explored, including a dose–response effect for the severity and frequency of victimization. Suggestions for targeting intervention are also suggested alongside clinical implications and recommendations for future research.

This paper explores the interaction between rural development policy and spatial planning policies for rural housing within the context of the island of Ireland. It draws on research commissioned by the Northern Ireland Housing Executive for a high level review of its rural housing policy. The paper highlights issues of wider relevance comprising a strained relationship between rural communities and rural planning, and argues for the adoption of cultural, environmental and community values within the rural planning policy arena.

Over twenty years ago ‘Our Common Future’ presented a conceptualization and explanation of the concept of sustainable development. Since then numerous alternative definitions of the concept have been offered, of which at least some are exclusive to each other. At the same time, the role of business in the transition to sustainable development has increasingly received attention. Bringing these two trends in sustainable development together, this paper returns to the Brundtland version of the concept to examine to what extent the original principles of sustainable development are still embedded within key business guidelines, namely the UN Global Compact, the OECD Guidelines for Multinational Enterprises, the ICC Business Charter for Sustainable Development, the CAUX Principles, the Global Sullivan Principles and the CERES Principles. The findings suggest that these business guidelines tend to emphasize environmental rather than social aspects of sustainable development, in particular to the detriment of the original Brundtland prioritization of the needs of the poorest. Furthermore, the attention to environmental aspects stresses win-win situations and has a clear managerialist focus; whereas more conceptual environmental issues concerning systems interdependencies, critical thresholds or systemic limits to growth find little attention. The normative codes and principles targeted at the private sector thus not only add another voice to the multiple discourses on sustainable development but also contribute to a reinterpretation of the original agenda set by Brundtland towards conceptualizations of sustainable development around the needs of industrialised rather than developing countries.

The design of medical devices could be very much improved if robust tools were available for computational simulation of tissue response to the presence of the implant. Such tools require algorithms to simulate the response of tissues to mechanical and chemical stimuli. Available methodologies include those based on the principle of mechanical homeostasis, those which use continuum models to simulate biological constituents, and the cell-centred approach, which models cells as autonomous agents. In the latter approach, cell behaviour is governed by rules based on the state of the local environment around the cell; and informed by experiment. Tissue growth and differentiation requires simulating many of these cells together. In this paper, the methodology and applications of cell-centred techniques-with particular application to mechanobiology-are reviewed, and a cell-centred model of tissue formation in the lumen of an artery in response to the deployment of a stent is presented. The method is capable of capturing some of the most important aspects of restenosis, including nonlinear lesion growth with time. The approach taken in this paper provides a framework for simulating restenosis; the next step will be to couple it with more patient-specific geometries and quantitative parameter data.
