Friendships Moderate an Association Between a Dopamine Gene Variant and Political Ideology

Scholars in many fields have long noted the importance of social context in the development of political ideology. Recent work suggests that political ideology also has a heritable component, but no specific gene variant or combination of variants associated with political ideology have so far been identified. Here, we hypothesize that individuals with a genetic predisposition toward seeking out new experiences will tend to be more liberal, but only if they are embedded in a social context that provides them with multiple points of view. Using data from the National Longitudinal Study of Adolescent Health, we test this hypothesis by investigating an association between self-reported political ideology and the 7R variant of the dopamine receptor D4 gene (DRD4), which has previously been associated with novelty seeking. Among those with DRD4-7R, we find that the number of friendships a person has in adolescence is significantly associated with liberal political ideology. Among those without the gene variant, there is no association. This is the first study to elaborate a specific gene-environment interaction that contributes to ideological self-identification, and it highlights the importance of incorporating both nature and nurture into the study of political preferences.     

The Veil of Kyoto and the politics of greenhouse gas mitigation in Australia

This paper investigates how the Kyoto Protocol has framed political discourse and policy development of greenhouse gas mitigation in Australia. We argue that ‘Kyoto’ has created a veil over the climate issue in Australia in a number of ways. Firstly, its symbolic power has distracted attention from actual environmental outcomes while its accounting rules obscure the real level of carbon emissions and structural trends at the nation-state level. Secondly, a public policy tendency to commit to far off emission targets as a compromise to implementing legislation in the short term has also emerged on the back of Kyoto-style targets. Thirdly, Kyoto’s international flexibility mechanisms can lead to the diversion of mitigation investment away from the nation-state implementing carbon legislation. A final concern of the Kyoto approach is how it has shifted focus away from Australia as the world’s largest coal exporter towards China, its primary customer. While we recognise the crucial role aspirational targets and timetables play in capturing the imagination and coordinating action across nations, our central theme is that ‘Kyoto’ has overshadowed the implementation of other policies in Australia. Understanding how ‘Kyoto’ has framed debate and policy is thus crucial to promoting environmentally effective mitigation measures as nation-states move forward from COP15 in Copenhagen to forge a post-Kyoto international agreement. Recent elections in 2009 in Japan and America and developments at COP15 suggest positive scope for international action on climate change. However, the lesson from the 2007 election and subsequent events in Australia is a caution against elevating the symbolism of ‘Kyoto-style’ targets and timetables above the need for implementation of mitigation policies at the nation-state level.     

The defence of the Holy Land and the memory of the Maccabees

This article explores the evolving use of Maccabaean ideas in sources concerning the conduct of Christian holy warfare between the eleventh and thirteenth centuries. It demonstrates that the memory of the Maccabees and other Old Testament exemplars played an important role in shaping the idea of crusading and its subsequent evolution to encompass new frontiers in the Baltic and Iberia, as well as structural developments in crusading, such as the establishment of the military orders.     

Trauma and pathology of a buried dog from San Nicolas Island,California, U.S.A.

To date more intact dog remains have been found on San Nicolas than on any of the other seven California Channel Islands. However, little is known about them. During the 2007 summer field season we excavated a medium sized young male dog in a flexed burial position from a pit at CA-SNI-25, a large Native American village site. The dog exhibits hypodontia, noticeable tooth attrition, severe scapular trauma, and vertebral, rib, and phalanx pathologies. Most of the injuries appear to have resulted from a severe blunt force trauma of unknown origin and it is likely the dog would not have survived without human care. The results of our analysis contribute to the, somewhat limited, published data on archaeological dogs in California. In this paper we describe the biological characteristics of the dog especially his anomalies and pathologies and compare them with published reports of other North American archaeological dogs with similar conditions.     

Mechanisms of Failure and Slope Development in Rock Masses

This paper examines the mechanisms of failure in jointed rock slopes. The distribution of discontinuities is a significant control of rock-mass stability, determining the mechanism by which blocks fail from a cliff, and the consequent slope development through time. It is often assumed that the principles of single-block movements are geomechanically similar to those of larger, multiple-block rock-mass failures, under a given set of boundary conditions and controlling variables. Results presented here, based on computer modelling using the Universal Distinct Element Code (UDEC), show that such assumptions are not always correct. After a theoretical modelling exercise, real-world rock slopes were studied from the Portland Limestone outcrop of the Isle of Purbeck, England. There is good association between the theoretical results and model output for the fieldsites. The conclusions are thus useful in enhancing knowledge of jointed rock-mass failure conditions, and improving understanding of rock-slope development.     

The End of the Beginning?: Welsh Regional Policy and Objective One

'West Wales and the Valleys' now qualify for EU Objective One status, entitled to draw down up to 1.3 billion in EU funds, matched from public and private sources between 2000 and 2006. However, there are many issues raised by the process of organizing the subsequent programme. There are questions over policy focus in the economically diverse Objective One areas, how governance of these policies will work, and the wider implications of Objective One in financial and political terms. There is also debate over previous regional policy initiatives in a Wales that for many years had access to a relatively large share of the UK's regional policy budget and EU funds, yet still faced falling GDP per head as a proportion of the UK average, west Wales and the Valleys' very Objective One status relying on GDP per capita under 75% of the EU average.
