Investigation of failures in Irish raised bogs

This paper presents the results of field geophysical testing and laboratory testing of peat from Carn Park and Roosky raised bogs in the Irish Midlands. The motivation for the work was highlight the importance of these areas and to begin to attempt to understand the reasons for the failure of the bogs despite them having surface slopes of some 1°. It was found that the peat is typical of that of Irish raised bogs being up to 8m thick towards the “high” dome of the bogs. The peat is characterised by low density, high water content, high organic content, low undrained shear strength and high compressibility. The peat is also relatively permeable at in situ stress. Geophysical electrical resistivity tomography and ground penetrating radar data shows a clear thinning of the peat in the area of the failures corresponding to a reduction in volume from dewatering by edge drains/peat harvesting. This finding is supported by detailed water content measurements. It was also shown that the peat base topography is relatively flat and indicates that the observed surface movement has come from within the peat rather than from the material below the peat. Potential causes of the failures include conventional slope instability, the effect of seepage forces or the release of built-up gas in the peat mass. Further measurements are required in order to study these in more detail.

Asynchrony between the Greenland ice core chronology and the radiocarbon calibration curve? Evidence from Irish bogs

A significant cold event, deduced from the Greenland ice cores, took place between 8200 and 8000 cal. BP. Modeling of the event suggests that higher northern latitudes would have also experienced considerable decreases in precipitation and that Ireland would have witnessed one of the greatest depressions. However, no well-dated proxy record exists from the British Isles to test the model results. Here we present independent evidence for a phase of major pine recruitment on Irish bogs at around 8150 cal. BP. Dendrochronological dating of subfossil trees from three sites reveal synchronicity in germination across the region, indicative of a regional forcing, and allows for high-precision radiocarbon based dating. The inner-rings of 40% of all samples from the north of Ireland dating to the period 8500-7500 cal. BP fall within a 25-yr window. The concurrent colonization of pine on peatland is interpreted as drier conditions in the region and provides the first substantive proxy data in support of a significant hydrological change in the north of Ireland accompanying the 8.2 ka event. The dating uncertainties associated with the Irish pine record and the Greenland Ice Core Chronology 2005 (GICC05) do not allow for any overlap between the two. Our results indicate that the discrepancy could be an artifact of dating inaccuracy, and support a similar claim by Lohne et al. (2013) for the Younger Dryas boundaries. If real, this asynchrony will most likely have affected interpretations of previous proxy alignments.

‘Blessed are the young, for they shall inherit the national debt’: Solidarity between generations in the Irish crisis

Ireland has gained a reputation for peaceable acceptance of austerity following a European Union/International Monetary Fund bailout in 2010. While proponents of austerity praise Ireland’s stoicism, critics of global capitalism argue that individuals and families are paying for mistakes made by elites. However, little is known about the strategies people adopt to cope with cutbacks to welfare entitlements. Drawing on a study of solidarity between generations living in Ireland in 2011–12, this article explores the lived experience of economic crisis and austerity. One hundred interviews with people of all ages and socio-economic backgrounds are analysed using constructivist grounded theory. Data show how austerity impacts differentially according to socio-economic status. While solidarity between generations leads to re-distribution of resources within families, providing some security for people with access to family resources, it reinforces inequality at societal level. We conclude that reliance on family promotes ‘coping’ rather than ‘protesting’ responses to austerity.

The Great Recession and the changing distribution of economic vulnerability by social class:The Irish case

Ireland provides an interesting case study of the distributional consequences of the Great Recession. To explore such effects we develop a measure of economic vulnerability based on a multidimensional risk profile for income poverty, material deprivation and economic stress. In the context of conflicting expectations of trends in social class differentials, we provide a comparison of pre and post-recession periods. Our analysis reveals a doubling of levels of economic vulnerability and a significant change in multidimensional profiles. Income poverty became less closely associated with material deprivation and economic stress and the degree of polarization between vulnerable and non-vulnerable classes was significantly reduced. Economic vulnerability is highly stratified by social class for both pre and post-recession periods. Focusing on absolute change, the main contrast is between the salariat and the non-agricultural self-employed and the remaining classes; providing some support for notions of polarization. In terms of relative change the higher salariat, the non-agricultural self-employed, the semi-unskilled manual and those who never worked gained relative to the remaining classes. This provides support the notion of ‘middle class squeeze’. The changing relationship between social class and household work intensity reflected a similar pattern. The impact of the latter on economic vulnerability declined sharply, while it came to play an increasing role in mediating the impact of membership of the non-agricultural middle classes. Responding to the political pressures likely to be associated with ‘middle class squeeze’ while sustaining the social welfare arrangements that have traditionally protected the economically vulnerable presents formidable challenges in terms of maintaining social cohesion and political legitimacy.

National identity in a foreign context: Irish women accounting for their children’s national identity in England

Social psychologists have attempted to capture the ideological quality of the nation through a consideration of its taken-for-granted quality, whereby it forms an unnoticed ‘banal’ background to everyday life and is passively absorbed by its members in contrast to its ‘hot’, politically created and contested nature. Accordingly, national identity is assumed to be both passively absorbed from the national backdrop and actively acquired through national inculcation. This raises the question of how national identity is expressed, transmitted and acquired in a foreign context, where the banal national backdrop is unavailable to scaffold identity and the national resources for identity transmission may be unavailable. The present article addresses this gap by examining the situation of Irish women raising children in England. Critical discursive analyses of the 16 interviews revealed that all women treated their children’s national identity and the issue of transmitting identity as dilemmatic: passive transmission risks children passively absorbing English, but active transmission contravenes the assumed naturalness of national identity and can furthermore conflict with children’s own personal choice. These results point to the complex interaction between the management of national identity and the broader personal and national context within which this occurs.

“Do You Want to See My Hornpipe?”: The Traditional Irish Dancing Body at Play in the Work of Jean Butler and Colin Dunne.

This chapter considers the radical re-imaginings of traditional Irish step dance in the recent works of Jean Butler and Colin Dunne. In Butler's Does She Take Sugar (2007) and Dunne's Out of Time (2008), the Irish step dancing body is separated from its historical roots in nationalism, from the exhibitionism required by the competitive form, and from the spectacularization of the commercialized theatrical format. In these works, which are both solo pieces performed by the choreographers themselves, the traditional form undergoes a critical interrogation in which the dancers attempt to depart from the determinacy of the traditional technique, while acknowledging its formation of their corporealities; the Irish step dance technique becomes a springboard for creative experimentation. In order to consider the importance of the creative potential revealed by these works, this chapter will contextualize them within the dance background from which they emerged, outlining the history of competitive step dancing in Ireland, the "modernization" of traditional Irish dance with the emergence of Riverdance (1994), and the experiments of Ireland's national folk theatre, Siamsa Tíre.

No evidence that runs of homozygosity are associated with schizophrenia in an Irish genome-wide association dataset

Runs of homozygosity (ROH), regions of the genome containing many consecutive homozygous SNPs, may represent two copies of a haplotype inherited from a common ancestor. A rare variant on this haplotype could thus be present in a homozygous and potentially recessive state. To detect rare risk variants for schizophrenia, we performed an ROH analysis in a homogeneous Irish genome wide association study (GWAS) dataset consisting of 1606 cases and 1794 controls. There was no genome-wide excess of ROH in cases compared to controls (p=0.7986). No consensus ROH at individual loci showed association with schizophrenia after genome-wide correction.
