Explaining the multiparty systems of Western Europe prior to the adoption of proportional representation

The literature has difficulty explaining why the number of parties in majoritarian electoral systems often exceeds the two-party predictions associated with Duverger’s Law. To understand why this is the case, I examine several party systems in Western Europe before the adoption of proportional representation. Drawing from the social cleavage approach, I argue that the emergence of multiparty systems was because of the development of the class cleavage, which provided a base of voters sizeable enough to support third parties. However, in countries where the class cleavage became the largest cleavage, the class divide displaced other cleavages and the number of parties began to converge on two. The results show that the effect of the class cleavage was nonlinear, producing the greatest party system fragmentation in countries where class cleavages were present – but not dominant – and smaller in countries where class cleavages were either dominant or non-existent.

Estimating the incidence, prevalence and true cost of asthma in the UK: Secondary analysis of national stand-alone and linked databases in England, Northern Ireland, Scotland and Wales-a study protocol

Introduction Asthma is now one of the most common long-term conditions in the UK. It is therefore important to develop a comprehensive appreciation of the healthcare and societal costs in order to inform decisions on care provision and planning. We plan to build on our earlier estimates of national prevalence and costs from asthma by filling the data gaps previously identified in relation to healthcare and broadening the field of enquiry to include societal costs. This work will provide the first UK-wide estimates of the costs of asthma. In the context of asthma for the UK and its member countries (ie, England, Northern Ireland, Scotland and Wales), we seek to: (1) produce a detailed overview of estimates of incidence, prevalence and healthcare utilisation; (2) estimate health and societal costs; (3) identify any remaining information gaps and explore the feasibility of filling these and (4) provide insights into future research that has the potential to inform changes in policy leading to the provision of more cost-effective care.

Methods and analysis Secondary analyses of data from national health surveys, primary care, prescribing, emergency care, hospital, mortality and administrative data sources will be undertaken to estimate prevalence, healthcare utilisation and outcomes from asthma. Data linkages and economic modelling will be undertaken in an attempt to populate data gaps and estimate costs. Separate prevalence and cost estimates will be calculated for each of the UK-member countries and these will then be aggregated to generate UK-wide estimates.

Ethics and dissemination Approvals have been obtained from the NHS Scotland Information Services Division's Privacy Advisory Committee, the Secure Anonymised Information Linkage Collaboration Review System, the NHS South-East Scotland Research Ethics Service and The University of Edinburgh's Centre for Population Health Sciences Research Ethics Committee. We will produce a report for Asthma-UK, submit papers to peer-reviewed journals and construct an interactive map.

Challenges in secondary prevention of cardiovascular diseases: A review of the current practice

With the changing demography of populations and increasing prevalence of co-morbidity, frail patients and more complex cardiac conditions, the modern medicine is facing novel challenges leading to rapid innovation where evidence and experiences are lacking. This scenario is also evident in cardiovascular disease prevention, which continuously needs to accommodate its ever changing strategies, settings, and goals. The present paper summarises actual challenges of secondary prevention, and discusses how this intervention should not only be effective but also efficient. By this way the paper tries to bridge the gaps between research and real-world findings and thereby may find ways to improve standard care.

Evaluation of a partnership between primary and secondary care providing an accessible Level 1 sexual health service in the community

Comprehensive testing for asymptomatic sexually transmitted infections in Northern Ireland has traditionally been provided by genitourinary medicine clinics. As patient demand for services has increased while budgets have remained limited, there has been increasing difficulty in accommodating this demand. In May 2013, the newly commissioned specialist Sexual Health service in the South Eastern Trust sought to pilot a new model of care working alongside a GP partnership of 12 practices. A training programme to enable GPs and practice nurses to deliver Level 1 sexual health care to heterosexual patients aged >16 years, in accordance with the standards of BASHH, was developed. A comprehensive care pathway and dedicated community health advisor supported this new model with close liaison between primary and secondary care. Testing for Chlamydia, gonorrhoea, HIV and syphilis was offered. The aims of the pilot were achieved, namely to provide accessible, cost-effective sexual health care within a framework of robust clinical governance. Furthermore, it uncovered a high positivity rate for Chlamydia, especially in young men attending their general practice, and demonstrated a high level of patient satisfaction. Moreover the capacity of secondary care to deliver Levels 2 and 3 services was increased.

Provision of resin bonded bridgework for a patient with microstomia secondary to scleroderma

Scleroderma is a connective tissue disorder that can present with orofacial involvement. A 48 year-old patient presented to Cork University Dental Hospital with concerns about the appearance of her upper central incisor teeth, which had become progressively mobile in recent years. A diagnosis of localised scleroderma had been made a number of years previously by her medical practitioner and the patient reported that her scleroderma-associated microstomia had progressed significantly in recent years. Most reports of this condition advocate the use of sectional impression trays and sectional dentures to replace missing teeth. This report describes the use of resin-bonded bridgework (RBB) and discusses the possible advantages of this treatment option over those already presented in the literature.

On Irish sticklebacks: morphological diversification in a secondary contact zone

Question: How parallel is adaptive evolution when it occurs from different genetic backgrounds?
Background: Divergent evolutionary lineages of several post-glacial fish species including the threespine stickleback are found together in Ireland.
Goals: To investigate the morphological diversity of stickleback populations in Ireland and assess whether morphology evolved in parallel between evolutionary lineages.
Methods: We sampled stickleback from lake, river, and coastal habitats across Ireland. Microsatellite and mitochondrial DNA data revealed evolutionary history. Geometric morphometrics and linear trait measurements characterized morphology. We used a multivariate approach to quantify parallel and non-parallel divergence within and between lineages.
Results: Repeated evolution of similar morphologies in similar habitats occurred across Ireland, concordant with patterns observed elsewhere in the stickleback distribution. A strong pattern of habitat-specific morphology existed even among divergent lineages. Furthermore, a strong signal of shared morphological divergence occurred along a marine–freshwater axis. Evidently, deterministic natural selection played a more important role in driving freshwater adaptation than independent evolutionary history.

Northern Ireland Representation at Westminster: Constitutional Conundrums and Political Manoeuvres

This article focuses on the issue of Northern Ireland's representation at Westminster. It investigates the political context of the decision to increase Northern Ireland's representation in the house of commons at Westminster from 12 members to 17 in 1978-9. Exploring this episode in more detail, it is argued, provides a more informed overall understanding of the history of devolution in the UK and of the way issues concerning Northern Ireland often overlapped with questions of constitutional change in Scotland and Wales. The article also throws light on the matter of Northern Ireland MPs and their voting rights at Westminster during Northern Ireland's experience of devolution prior to 1972.

An analysis of implied volatility jump dynamics: Novel functional data representation in crude oil markets

The predominant fear in capital markets is that of a price spike. Commodity markets differ in that there is a fear of both upward and down jumps, this results in implied volatility curves displaying distinct shapes when compared to equity markets. The use of a novel functional data analysis (FDA) approach, provides a framework to produce and interpret functional objects that characterise the underlying dynamics of oil future options. We use the FDA framework to examine implied volatility, jump risk, and pricing dynamics within crude oil markets. Examining a WTI crude oil sample for the 2007–2013 period, which includes the global financial crisis and the Arab Spring, strong evidence is found of converse jump dynamics during periods of demand and supply side weakness. This is used as a basis for an FDA-derived Merton (1976) jump diffusion optimised delta hedging strategy, which exhibits superior portfolio management results over traditional methods.

Behind the Headlines: Media Representation of Children and Young People in Northern Ireland:Summary of Research Findings

Funded by the Economic and Social Research Council this partnership project between the Childhood, Transition and Social Justice Initiative at Queen’s University and Include Youth focuses on the negative stereotyping of children and young people and the role and responsibilities of the media in the creation and transmission of negative images. Engaging with children, young people, organisations working with children and young people and media representatives, the project uses research evidence to explore negative media representation and its consequences for children’s rights, public reaction and policy initiatives in Northern Ireland. This report represents a summary of the findings of engagement with 141 children and young people. It outlines how they feel they are presented by the media and the impacts of this. It concludes by noting ways forward in challenging negative portrayals.

A-level Mathematics Options – Views of Secondary-level Teachers

The A-level Mathematics qualification is based on a compulsory set of pure maths modules and a selection of applied maths modules with the pure maths representing two thirds of the assessment. The applied maths section includes mechanics, statistics and (sometimes) decision maths. A combination of mechanics and statistics tends to be the most popular choice by far. The current study aims to understand how maths teachers in secondary education make decisions regarding the curriculum options and offers useful insight to those currently designing the new A-level specifications.

Semi-structured interviews were conducted with A-level maths teachers representing 27 grammar schools across Northern Ireland. Teachers were generally in agreement regarding the importance of pure maths and the balance between pure and applied within the A-level maths curriculum. A wide variety of opinions existed concerning the applied options. While many believe that the basic mechanics-statistics (M1-S1) combination is most accessible, it was also noted that the M1-M2 combination fits neatly alongside A-level physics. Lack of resources, timetabling constraints and competition with other subjects in the curriculum hinder uptake of A-level Further Maths.

Teachers are very conscious of the need to obtain high grades to benefit both their pupils and the school’s reputation. The move to a linear assessment system in England while Northern Ireland retains the modular system is likely to cause some schools to review their choice of exam board although there is disagreement as to whether a modular or linear system is more advantageous for pupils. The upcoming change in the specification offers an opportunity to refresh the assessment also and reduce the number of leading questions. However, teachers note that there are serious issues with GCSE maths and these have implications for A-level.
