When Shiels met Liberace: a skirmish with the canon of Irish theatre

Just Shiels, the product of one of the first practice as research programmes undertaken by a theatre professional within the environment of an Irish university, ‘activates’ in performance the archives of the Northern Irish dramatist George Shiels (1881–1949). The play explores Shiels's marginalization from the canon of Irish theatre on grounds of his embodied position as a disabled person, his status as a Northerner writing plays to be performed across the border in the new free Irish state, his geographical peripherality to the centre of theatrical activity in Dublin and his choice of popular forms in his dramaturgy. Just Shiels was first performed in May 2008 at Queen's University Drama Centre, Belfast. This article seeks to explore to what degree Shiels's choice of popular forms and his serious physical impairment might be implicated in his marginalization. It was first delivered as a plenary session to the American Conference for Irish Studies in New York, in October 2008.

Atomic ordering in nano-layered FePt

Monte Carlo simulation of chemical ordering kinetics in nano-layered L1₀ AB binary intermetallics was performed. The study addressed FePt thin layers considered as a material for ultra-high-density magnetic storage media and revealed metastability of the L1₀ c-variant superstructure with monoatomic planes parallel to the surface and off-plane easy magnetization. The layers, originally perfectly ordered in a c-variant of the L1₀ superstructure, showed homogeneous disordering running in parallel with a spontaneous re-orientation of the monoatomic planes leading to a mosaic microstructure composed of a- and b-L1₀-variant domains. The domains nucleated heterogeneously on the surface of the layer and grew discontinuously inwards its volume. Finally, the domains relaxed towards an equilibrium microstructure of the system. Two “atomistic-scale” processes: (i) homogeneous disordering and (ii) nucleation of the a- and b-L1₀-variant domains showed characteristic time scales. The same was observed for the domain microstructure relaxation. The discontinuous domain growth showed no definite driving force and proceeded due to thermal fluctuations. The above complex structural evolution has recently been observed experimentally in epitaxially deposited thin films of FePt.

Ireland's Innovation Performance: 1991-2005

In this paper we use data from the five waves of the Irish Innovation Panel (IIP) to profile the innovation performance of manufacturing plants in Ireland and Northern Ireland over the period 1991 to 2005. Despite considerable public sector investment on both sides of the border levels of innovation activity have remained broadly similar throughout this period although somewhat different trends are evident in Ireland and Northern Ireland. In terms of product innovation for example, the proportion of manufacturing plants making product changes has increased 5 per cent in Ireland and just over 7 per cent in Northern Ireland. In terms of process innovation a decline of almost 7 per cent in Ireland has been accompanied by a 7 per cent increase in Northern Ireland. These trends provide some evidence of convergence in innovation performance over the 1991 to 2005 period. This is evident in the narrowing gap between the proportion of product innovators in Ireland and Northern Ireland, convergence in the proportion of plants undertaking process innovation and in terms of the increasingly similar proportions of sales derived from innovative products. Looking in more detail at the determinants of manufacturing innovation emphasises the importance of R&D and backwards supply chain linkages as sources of new knowledge for innovation. Other external linkages prove less important suggesting the value of policy initiatives designed to promote knowledge sharing. We also find a significant negative innovation effect from legislative restrictions on plants’ product innovation. Public support for both product and process innovation are having positive effects on innovation outputs at the level of the individual plant. Future research interest centres on the contrast between this strong positive result at firm level and the more modest increases in innovation among the population of firms in Ireland and Northern Ireland.

Modelling the effect of water immersion thermal processing on polyacetylene levels and instrumental colour of carrot disks

C₁₇ polyacetylenes are a group of bioactive compounds present in carrots which have recently gained scientific attention due to their cytotoxicity against cancer cells. In common with many bioactive compounds, their levels may be influenced by thermal processes, such as boiling or water immersion. This study investigated the effect of a number of water immersion time/temperature combinations on concentrations of these compounds and attempted to model the changes. Carrot samples were thermally treated by heating in water at temperatures from 50–100 °C and holding times of 2–60 min. Following heating, levels of falcarinol (FaOH), falcarindiol (FaDOH), falcarindiol-3-acetate (FaDOAc) and Hunter colour parameters (L^*, a^*, b^*) were determined. FaOH, FaDOH, FaDOAc levels were significantly reduced at lower temperatures (50–60 °C). In contrast, samples heated at temperatures from 70–100 °C exhibited higher levels of polyacetylenes (p < 0.05) than did raw unprocessed samples. Regression modelling was used to model the effects of temperature and holding time on the levels of the variables measured. Temperature treatment and holding time were found to significantly affect the polyacetylene content of carrot disks. Predicted models were found to be significant (p < 0.05) with high coefficients of determination (R²).

A burning issue? Governance and anti-incinerator campaigns in Ireland, North and South

The decades of conflict in Northern Ireland created divisions between communities, with few opportunities for cooperation. However, in the 1990s opposition to a proposed cross-border incinerator brought the divided communities together. The 1990s economic boom in the Republic of Ireland generated a waste management crisis as the by-products of rampant consumerism overwhelmed the state's rudimentary waste disposal system. Three Irish anti-incinerator campaigns which have pitted local communities against the Irish state or the Northern Ireland Department of the Environment are examined. Community attempts to gain leverage within the political governance frameworks in operation on both sides of the border are examined and the various ways in which environmental movements respond to the crisis of waste management under different governance regimes are illuminated.

‘Towards a Green New Deal on the Island of Ireland: from economic crisis to a new political economy of sustainability’

This article begins from the assumption (which may seem controversial to many) that anyone who thinks that our current economic crisis is a temporary blip until ‘normal service’ (i.e. a return to ‘business as usual’) is resumed, profoundly misunderstands the severity and significance of what’s happening to the global economy and its impacts on the future prosperity of the island of Ireland. The economic recession represents nothing short of a re-structuring of the global economy and the creation of a new dispensation between governments, markets and citizens. The full implications of the re-regulation of the market, with the state bailing out and part nationalising the financial sector in both jurisdictions on the island (as in other parts of the world) have yet to be seen, but what we are witnessing is the emergence of a new economic model. Those who think we can, or even ought to, return to the pre-2008 economic model, are gravely mistaken. The current economic downturn marks the end of the ‘neo-liberal’ model and the beginnings of the transition (an inevitable transition, this article will argue) towards a new low carbon, renewable, green and sustainable economy and society.

Theory of the Kinetics of Chemical Potentials in Heterogeneous Catalysis

Simple and powerful: The reaction kinetics at surfaces of heterogeneous catalysts is reformulated in terms of the involved chemical potentials. Based on this formulism, an approach of searching for good catalysts is proposed without recourse to extensive calculations of reaction barriers and detailed kinetic analyses. (see picture; R=reactant, I=surface intermediate, P=product, and =standard chemical potential).

THE GULL-TAPEWORM, DIPHYLLOBOTHRIUM-DENDRITICUM AND NEUROPEPTIDE-F - AN IMMUNOCYTOCHEMICAL STUDY

Neuropeptide F (Moniezia expansa) immunoreactivity (NPF-IR) has been detected in the nervous system of plerocercoid and adult stages of the gull-tapeworm Diphyllobothrium dendriticum, using immunocytochemical methodology. The application of the antiserum for this authentic flatworm neuropeptide to whole-mounts and frozen sections of the worm has resulted in new information about its neuroanatomy. Thus, at regular intervals, transverse nerves extend from the main nerve cords laterally, joining the longitudinal lateral minor cords in the cortical parenchyma. In the adult worm, the transverse nerves are located at the posterior border of each proglottis. The medullary parenchyma lacks NPF-IR. The NPF-immunoreactive cell bodies are bi- to multipolar and preferentially located in the peripheral nervous system, in close association with the holdfast musculature of the scolex and the extensive body musculature. NPF-IR was observed in the innervation to the muscular ducts of the reproductive system. The pattern of NPF-IR was compared with that recorded for RFamide- and 5-HT-IR and double-immunostaining has revealed separate populations of serotoninergic and peptidergic neurones.

Chemical and mechanical stability of sodium sulfate activated slag after exposure to elevated temperature

The chemical and mechanical stability of slag activated with two different concentrations of sodium sulfate (Na₂SO₄) after exposure to elevated temperatures ranging from 200 to 800 °C with an increment of 200 °C has been examined. Compressive strengths and pH of the hardened pastes before and after the exposure were determined. The various decomposition phases formed were identified using X-ray diffraction, thermogravimetric analysis and scanning electron microscopy. The results indicated that Na₂SO₄ activated slag has a better resistance to the degradation caused by exposure to elevated temperature up to 600 °C than Portland cement system as its relative strengths are superior. The finer slag and higher Na₂SO₄ concentration gave better temperature resistance. Whilst the pH of the hardened pastes decreased with an increase in temperature, it still maintained a sufficiently high pH for the protection of reinforcing bar against corrosion.

Utilising Creative Methodologies to Elicit the Views of Young Learners with Additional Needs in Literacy

The research described in this article aimed to explore and examine the dominant ‘assessment’ and ‘participation’ stories of upper-primary pupils with long-standing and marked literacy learning needs, their views on how their level of participation in the assessment and remediation of their additional needs might be increased and also how they perceive themselves as literacy learners. This qualitative small-scale study adopted a case study approach and utilised creative methodologies in the context of focus groups to investigate sensitively theviews and experiences of Key Stage 2 pupils with additional needs in literacy. The findings discussed here are based on the outcomes from the four Northern Irish schools that participated in the original cross-border (Northern Ireland/Republic of Ireland) study. Findings are discussed in the context of strategies for promotingholistic and empowering pathways for learners with additional needs in literacy.
