Democratic Participation, Engagement, and Freedom

It is commonly supposed that democracies should encourage greater political participation and civic engagement. This article identifies two distinct perspectives on political participation and civic engagement: a ‘freedom-centred’ model and an ‘ethical’ model. The ‘freedom-centred’ model defended here draws on the republican concept of freedom as non-domination, together with the political liberal notion of fair deliberative proceduralism, while the ethical model draws on Aristotelian, perfectionist, sources. It is argued that the ‘ethical’ model is overly concerned with the ‘moral renewal’ of modern social life, and is insensitive to problems of domination posed by its account of civic reciprocity and trust. By contrast, the ‘freedom-centred’ model developed offers a systematic account of personal and political freedom, which provides qualified support for deliberative modes of participation and engagement.

Devolution and the politics of development in Northern Ireland

The reintroduction of devolution in Northern Ireland is widely interpreted as the working out of the Belfast Agreement (1998) which aimed to embed political consensus in shared institutions of the state. However, such analysis tends to be limited with regard to wider political economy readings of the devolution project and historic struggles to find an appropriate institutional fix to manage different
forms of crisis. Peace and stability have, it is argued, permitted Northern Ireland's reentry to global markets and circuits of capital with new governance structures being assembled to reconfigure `post- conflict' economic space. We argue that the onset of devolution has promoted a mix between ethnosectarian resource competition and a constantly expanding neoliberal model of governance.
Devolved neoliberal structures that sustain social polarisation may perpetuate strategies of resistance that could cut across and challenge ethnosectarian politics and deepening social segregation.

Initial Studies on the Occurrence of Cyanobacteria and Microcystins in Irish Lakes

We report the results of a synoptic survey at 14 sites across the north of Ireland undertaken to determine the occurrence of cyanobacteria and their constituent microcystin cyanotoxins. Seven microcystin toxins were tested for, and five of which were found, with MC-LR, MC-RR, and MC-YR being the most prevalent. Gomphosphaeria spp and Microcystis aeruginosa were the most dominant cyanobacterial species encountered. Together with Aphanizomenon flos-aquae, these were the cyanobacteria associated with the highest microcystin concentrations. The occurrence of several microcystin toxins indicates that there may potentially be more than one cyanobacteria species producing microcystins at many sites. Total microcystin concentrations varied over three orders of magnitude dividing the sites into two groups of high (>1000 ngMC/μgChla, six sites) or low toxicity (<200 ngMC/μgChla, eight sites). © 2010 Wiley Periodicals, Inc.

User behaviour, best practice and the risks of non-target exposure associated with anticoagulant rodenticide use

Usage of anticoagulant rodenticides (ARs) is an integral component of modern agriculture and is essential for the control of commensal rodent populations. However, the extensive deployment of ARs has led to widespread exposure of a range of non-target predatory birds and mammals to some compounds, in particular the second-generation anticoagulant rodenticides (SCARS). As a result, there has been considerable effort placed into devising voluntary best practice guidelines that increase the efficacy of rodent control and reduce the risk of non-target exposure. Currently, there is limited published information on actual practice amongst users or implementation of best practice. We assessed the behaviour of a typical group of users using an on-farm questionnaire survey. Most baited for rodents every year using SGARs. Most respondents were apparently aware of the risks of non-target exposure and adhered to some of the best practice recommendations but total compliance was rare. Our questionnaire revealed that users of first generation anticoagulant rodenticides rarely protected or checked bait stations, and so took little effort to prevent primary exposure of non-targets. Users almost never searched for and removed poisoned carcasses and many baited for prolonged periods or permanently. These factors are all likely to enhance the likelihood of primary and secondary exposure of non-target species. (C) 2010 Published by Elsevier Ltd.

Increasing the accuracy of Nitrogen Dioxide (NO2) pollution mapping using geographically weighted regression (GWR) and geostatistics.

Nitrogen Dioxide (NO2) is known to act as an environmental trigger for many respiratory illnesses. As a pollutant it is difficult to map accurately, as concentrations can vary greatly over small distances. In this study three geostatistical techniques were compared, producing maps of NO2 concentrations in the United Kingdom (UK). The primary data source for each technique was NO2 point data, generated from background automatic monitoring and background diffusion tubes, which are analysed by different laboratories on behalf of local councils and authorities in the UK. The techniques used were simple kriging (SK), ordinary kriging (OK) and simple kriging with a locally varying mean (SKlm). SK and OK make use of the primary variable only. SKlm differs in that it utilises additional data to inform prediction, and hence potentially reduces uncertainty. The secondary data source was Oxides of Nitrogen (NOx) derived from dispersion modelling outputs, at 1km x 1km resolution for the UK. These data were used to define the locally varying mean in SKlm, using two regression approaches: (i) global regression (GR) and (ii) geographically weighted regression (GWR). Based upon summary statistics and cross-validation prediction errors, SKlm using GWR derived local means produced the most accurate predictions. Therefore, using GWR to inform SKlm was beneficial in this study.

Is everybody happy? The politics and measurement of national wellbeing

This article explores the political and intellectual influences behind the growth of interest in happiness and the emergence of the new 'science of happiness'. It offers a critique of the use of subjective wellbeing indicators within indexes of social and economic progress, and argues that the proposed United Kingdom's National Well-being Index is over-reliant on subjective measures. We conclude by arguing that the mainstreaming of happiness indicators reflects and supports the emergence of 'behavioural social policy'.

From the Land to Sea and Back Again? Using Terrestrial Planning to Understand the Process of Marine Spatial Planning

Over the last 5–10 years, marine spatial planning (MSP) has emerged as a new management regime for national and international waters and has already attracted a substantial body of multi-disciplinary research on its goals and policy processes. This paper argues that this literature has generally lacked deeper reflexive engagement with the emerging system of governance for our seas that has meant that many of MSP’s core concepts, assumptions and institutional arrangements have not been subject rigorous intellectual debate. In an attempt to initiate such an approach, this article explores the relationship between MSP and its land-based cousin, terrestrial spatial planning (TSP). While it is recognized that there are inherent limitations to a comparison of these two systems, it is argued that the tradition of social science debate over the purpose and processes of TSP can be used as a useful stimulus for a more rigorous reflection of such issues as they relate to MSP. The article therefore explores some of the parallels between MSP and TSP and then discusses some of the key intellectual traditions that have shaped TSP and the implications these may have for future marine planning practice. The article concludes with a number of potentially useful new avenues that may form the basis of a critical research agenda for MSP.

Random Regret Minimization: Exploration of a New Choice Model for Environmental and Resource Economics

This paper introduces the discrete choice model-paradigm of Random Regret Minimization (RRM) to the field of environmental and resource economics. The RRM-approach has been very recently developed in the context of travel demand modelling and presents a tractable, regret-based alternative to the dominant choice-modelling paradigm based on Random Utility Maximization-theory (RUM-theory). We highlight how RRM-based models provide closed form, logit-type formulations for choice probabilities that allow for capturing semi-compensatory behaviour and choice set-composition effects while being equally parsimonious as their utilitarian counterparts. Using data from a Stated Choice-experiment aimed at identifying valuations of characteristics of nature parks, we compare RRM-based models and RUM-based models in terms of parameter estimates, goodness of fit, elasticities and consequential policy implications.

Northern Visions? Applying Q methodology to understand stakeholder views on the environmental and resource dimensions of sustainability

Q methodology was used to enable the identification of discourses among stakeholders to the environmental and resource dimensions of sustainability policies and to gain an understanding of the usefulness of Q methodology in informing sustainability policy development. The application of Q methodology has been useful in identifying shared discourses between different stakeholder groups, and providing insights into how stakeholders frame or understand policy issues; and recommendations are made for ongoing research priorities. These insights, in turn, informed the choice of scenarios for an in parallel process of policy evaluation using Ecological and Carbon Footprinting.

Ordering effects and choice set awareness in repeat-response stated preference studies

We present an experiment designed to investigate the presence and nature of ordering effects within repeat-response stated preference (SP) studies. Our experiment takes the form of a large sample, full-factorial, discrete choice SP exercise investigating preferences for tap water quality improvements. Our study simultaneously investigates a variety of different forms of position-dependent and precedent-dependent ordering effect in preferences for attributes and options and in response randomness. We also examine whether advanced disclosure of the choice tasks impacts on the probability of exhibiting ordering effects of those different types. We analyze our data both non-parametrically and parametrically and find robust evidence for ordering effects. We also find that the patterns of order effect in respondents' preferences are significantly changed but not eradicated by the advanced disclosure of choice tasks a finding that offers insights into the choice behaviors underpinning order effects. © 2011 Elsevier Inc.

Celtic nationalism and supranationalism: comparing Scottish and Northern Ireland party responses to Europe

This article explores how stateless nationalist parties in the ‘Celtic periphery’ of Scotland and Northern Ireland have used Europe to advance their territorial projects. Despite vastly different historical, political and social contexts, the Scottish National Party and Northern Ireland's Social Democratic and Labour Party have both advanced a pro-European, social democratic discourse that emphasises the importance of Europe as a framework for constitutional reform and shared sovereignty. However, in recent years the parties have diverged on Europe. While the SDLP has continued its principled commitment to further integration, the SNP has articulated an increased criticism of the supranational project. This divergence in party attitudes reveals the extent to which the pro-European dimension of Celtic nationalism is ideological or opportunistic.

Essential and toxic elements in infant foods from Spain, UK, China and USA

Spanish gluten-free rice, cereals with gluten, and pureed baby foods were analysed for essential macro-elements (Ca and Na), essential trace elements (Fe, Cu, Zn, Mn, Se, Cr, Co and Ni) and non-essential trace elements (As, Pb, Cd and Hg) using ICP-MS and AAS. Baby cereals were an excellent source of most of the essential elements (Ca, Fe, Cu, Mn and Zn). Sodium content was high in pureed foods to improve their flavour; fish products were also rich in Se. USA pure baby rice samples had the highest contents of all studied essential elements, showing a different nutrient pattern compared to those of other countries. Mineral fortification was not always properly stated in the labelling of infant foods. Complementary infant foods may also contain significant amounts of contaminants. The contents of Hg and Cd were low enough to guarantee the safety of these infant foods. However, it will be necessary to identify the source and reduce the levels of Pb, Cr and As in Spanish foods. Pure baby rice samples contained too much: Pb in Spain; As in UK; As, Cr and Ni in USA; and Cr and Cd in China.

Arsenic speciation in Japanese rice drinks and condiments

Rice has been demonstrated to be one of the major contributors to inorganic arsenic (i-As) intake in humans. However, little is known about rice products as additional source of i-As exposure. In this study, misos, syrups and amazake (a fermented sweet rice drink) produced from rice, barley and millet were analysed for total arsenic (t-As) and a subset of samples were also analyzed for As speciation. Rice based products displayed a higher i-As content than those derived from barley and millet. Most of the t-As in the rice products studied was inorganic (63-83%), the remainder being dimethylarsinic acid. Those who regularly consume rice drinks and condiments, such as the Japanese population and those who follow health conscious diets based on the Japanese cuisine, could reach up to 23% of the World Health Organization's Provisional Tolerable Daily Intake of i-As, by only consuming these kinds of products. This study provides a wide appreciation of how i-As derived from rice based products enters the human diet and how this may be of concern to populations who are already exposed to high levels of i-As through consumption of foods such as rice and seaweed.
