Characterization of urban aerosol in Cork city (Ireland) using aerosol mass spectrometry

Ambient wintertime background urban aerosol in Cork city, Ireland, was characterized using aerosol mass spectrometry. During the three-week measurement study in 2009, 93% of the ca. 1 350 000 single particles characterized by an Aerosol Time-of-Flight Mass Spectrometer (TSI ATOFMS) were classified into five organic-rich particle types, internally mixed to different proportions with elemental carbon (EC), sulphate and nitrate, while the remaining 7% was predominantly inorganic in nature. Non-refractory PM1 aerosol was characterized using a High Resolution Time-of-Flight Aerosol Mass Spectrometer (Aerodyne HR-ToF-AMS) and was also found to comprise organic aerosol as the most abundant species (62 %), followed by nitrate (15 %), sulphate (9 %) and ammonium (9 %), and chloride (5 %). Positive matrix factorization (PMF) was applied to the HR-ToF-AMS organic matrix, and a five-factor solution was found to describe the variance in the data well. Specifically, "hydrocarbon-like" organic aerosol (HOA) comprised 20% of the mass, "low-volatility" oxygenated organic aerosol (LV-OOA) comprised 18 %, "biomass burning" organic aerosol (BBOA) comprised 23 %, non-wood solid-fuel combustion "peat and coal" organic aerosol (PCOA) comprised 21 %, and finally a species type characterized by primary m/z peaks at 41 and 55, similar to previously reported "cooking" organic aerosol (COA), but possessing different diurnal variations to what would be expected for cooking activities, contributed 18 %. Correlations between the different particle types obtained by the two aerosol mass spectrometers are also discussed. Despite wood, coal and peat being minor fuel types used for domestic space heating in urban areas, their relatively low combustion efficiencies result in a significant contribution to PM1 aerosol mass (44% and 28% of the total organic aerosol mass and non-refractory total PM1, respectively).Ambient wintertime background urban aerosol in Cork city, Ireland, was characterized using aerosol mass spectrometry.

Source apportionment of PM2.5 in Cork Harbour, Ireland using a combination of single particle mass spectrometry and quantitative semi-continuous measurements

An aerosol time-of-flight mass spectrometer (ATOFMS) was deployed for the measurement of the size resolved chemical composition of single particles at a site in Cork Harbour, Ireland for three weeks in August 2008. The ATOFMS was co-located with a suite of semi-continuous instrumentation for the measurement of particle number, elemental carbon (EC), organic carbon (OC), sulfate and particulate matter smaller than 2.5 μm in diameter (PM2.5). The temporality of the ambient ATOFMS particle classes was subsequently used in conjunction with the semi-continuous measurements to apportion PM2.5 mass using positive matrix factorisation. The synergy of the single particle classification procedure and positive matrix factorisation allowed for the identification of six factors, corresponding to vehicular traffic, marine, long-range transport, various combustion, domestic solid fuel combustion and shipping traffic with estimated contributions to the measured PM2.5 mass of 23%, 14%, 13%, 11%, 5% and 1.5% respectively. Shipping traffic was found to contribute 18% of the measured particle number (20–600 nm mobility diameter), and thus may have important implications for human health considering the size and composition of ship exhaust particles. The positive matrix factorisation procedure enabled a more refined interpretation of the single particle results by providing source contributions to PM2.5 mass, while the single particle data enabled the identification of additional factors not possible with typical semi-continuous measurements, including local shipping traffic.

A bookish history of Irish Romanticism

This chapter argues that authors of Irish Romantic novels and national tales, such as Maria Edgeworth and John and Michael Banim, are not only concerned with the extent to which their novels sought to copy from Irish culture but are also worried about the slightness of the novel form in relation to the copiousness of that culture. Such concerns led to attempts by Thomas Crofton Croker and others to add texture and tactility to their depictions of the Irish past, through antiquarian methodologies but also facsimiles, lithography, and other developments in print culture. The chapter demonstrates the ways in which Irish literary texts were concerned not only to accurately and minutely detail the past, but also to adduce evidence of such historical and cultural authenticity, working against teleological accounts of the birth of the modern historical method, which see Romantic history as unconcerned with the evidentiary foundations of the past.

The Catholic Church and revolution in Ireland

Despite the involvement of radical socialists like James Connolly and the Irish Citizen Army in the 1916 Rising and the unanimous passing of the Democratic Programme (a socialist manifesto for the new Government) by the First Dáil in 1919, the Irish state has since its inception exhibited a highly conservative approach to social and economic policy, and politics generally in Ireland, North or South, have never faced a serious challenge from those seeking radical change. Several factors have played a part in this and this article focuses on one of these - the power and conservatism of the Catholic Church and its influence in shaping the political landscape. Despite a decline in recent years, the Church remains influential north and south of the Border in education provision, the current debates in relation to abortion and in culturally important aspects of life - baptism, communion and burial. In the past the Church’s political influence among Ireland’s majority Catholic community had been even more pronounced. The article begins by looking at the Church’s attitude to revolutionary change in Ireland historically before focusing on its influence in the North during the Stormont years and during the more recent ‘Troubles’ – 1969 - 98. It shows how the Church attempted to influence political thought and discourse in Ireland when it was at the height of its power. Whilst it is true that the Church was not a monolith, and there have always been individual priests who have adopted a more radical approach, the general thrust of the Church was conservative, attempting to ally itself with the power elites of the day where possible. It is this influence which appears to have stood the test of time despite attempts in past generations to radicalise the Irish population.

Assessment in primary education in Ireland

This doctoral study examines assessment in primary education in the Republic of Ireland. The nature and purpose of assessment offer an insight into the values which are prioritised by an education system. In 2011, in the Republic of Ireland, the Department of Education and Skills (DES) published a strategy aiming to improve standards of literacy and numeracy. The document, entitled, Literacy and numeracy for learning and life: the national strategy to improve literacy and numeracy for children and young people 2011-2020, contains improvement targets as measured by standardised tests. It also mandates the increased use of standardised tests in primary education, and directs that aggregated scores should be reported to both Boards of Management and the DES. The study is framed by the theoretical perspectives of Michel Foucault and Pierre Bourdieu. Both of these commentators examine social policy and practice in an effort to provide insight into the history and operation of social institutions. This study is especially influenced by Foucault’s archaeology and genealogy of knowledge, and his notion of governmentality. It is also particularly cognisant of Bourdieu’s thoughts on habitus, doxa and capital. The study contains reviews of literature in the areas of assessment, assessment policy, and assessment policy in Ireland. These reviews highlight current debate in each of these areas while also grounding this debate in an historical context. The dissertation contains four empirical sections. 1) It analyses policy documents prepared in the development of the published strategy as well as investigating the strategy itself. In so doing it is aware of the burgeoning influence of pan-national bodies on policy development. 2) A number of high profile policy makers were interviewed as part of the study and their views are interpreted in light of the findings of the literature reviews. 3) The perspective of teachers was sought through a questionnaire survey. This gathered data on these teachers’ views on the purpose of assessment as well as their actual practice. 4) Finally, children were also included as participants in this study. They were interviewed in focus groups and encouraged to contribute drawings as well on their views of assessment in primary school. Literacy and numeracy for learning and life is seen as a seminal document in Irish education. This study is significant in its analysis of original data from high profile policy makers, including two Ministers for Education and Skills. It is also significant in its inclusion of the perspectives of primary school pupils. Finally, the study considers the nature and role of assessment in a holistic manner by including the views of policy makers, teachers and pupils. The study notes that policy development in Ireland underwent a change in the preparation of Literacy and numeracy for learning and life and that international influences, while present, are also mediated to suit the local context. It also highlights a lack of clarity in the definition of assessment in primary education and argues that there is a lack of balance in the approaches that are prioritised. The study demonstrates that teachers are impacted by the strategy but that they also change it by focusing on their own concerns while using assessment tools. The children provide compelling evidence of the impact of assessment on the learner. The study shows how assessment tools (and school subjects) are valued with differing levels of importance by a variety of stakeholders.

The Resurgence of Gaelic power in Ireland and Scotland and its wider impact, c.1350-1513

Over the course of the later Middle Ages nearly half the landmass of the British Isles fell under the control of a handful of Gaelic dynasties in Ireland and Scotland. The impact of this profound geopolitical recasting of much of the Atlantic Archipelago has however, received very little scholarly attention. Instead, historians have tended to view events within this expanding Gaelic world, or Gàidhealtachd, as peripheral to the political development of the British Isles and the course of Anglo-Scottish relations during the later Medieval period. Drawing upon a comprehensive range of sources from Ireland, Scotland, and England, as well as significant archival research, this thesis challenges the concept of the so-called 'Celtic fringe' and illustrates how developments within the Gàidhealtachd impacted upon the course of 'British' politics during the period c.1350-1513. The thesis centres on an examination of how two competing Gaelic alliance systems came to dominate much of the Gàidhealtachd from the late fourteenth century through to the early 1500s. The first of these alliance blocs was controlled chiefly by the O'Neills of Tyrone, the O'Briens of Thomond, and MacDonalds of the Hebrides; in the other network the O'Donnells of Tyrconnell, the Burkes of Mayo and the Campbells of Argyll held sway. By tracing the interconnectivity of the lordships in each respective network, the thesis investigates how these alliance systems became a durable force not only within the Gàidhealtachd but also on the broader 'British' stage. The thesis is structured in a manner that makes the intricate, lineage-based world of the Gàidhealtachd more accessible. Each chapter shifts between the various regions of the Gaelic world and examines how developments in one region impacted upon corresponding territory. Ultimately, this provides historians with a new model for exploring what has previously been a majorly neglected area of Irish and British history.

Too beautiful for thieves and pickpockets: a history of the Victorian convict prison on Spike Island

Spike Island holds a unique place among the world’s prisons: a welcome necessity for the prison authorities of Ireland, a remote and dangerous posting for its staff, a grand hell for those convicted to stay behind its walls. For almost four decades the Victorian prison on Spike Island was home to Ireland’s most serious and notorious criminals. Established in the midst of one of the worst famines in global history, this huge facility became the largest prison in what was then the United Kingdom, dwarfing institutions like Dartmoor, Pentonville, Mountjoy and Kilmainham. High death rates during its formative years meant that many of its malnourished inmates were laid to rest beneath its sod. Yet Spike Island was to become a beacon of penal reform, influencing modern correctional systems in countries as far apart as the USA and Germany. The story told in this book is one that is, in turn, dramatic, shocking, touching and humorous. The life of the prison was vibrant, peopled by the unfortunate of the society alongside those who committed serious, sometimes gruesome, crimes. This is the story of the establishment and evolution of the prison over 36 years, the often fascinating lives of prisoners and staff and of a time when a renowned Irish fortress of British military power entered the annals of penal infamy.

An archaeology of female monasticism in medieval Ireland

This thesis considers the archaeological evidence for female monasticism in medieval Ireland, with a particular emphasis on the later medieval period. Female monasticism has been considered from an archaeological perspective in several countries, most notably Britain, but has yet to be considered in any detail in Ireland. The study aims to bring together all the currently available evidence on female monasticism and consider it through an engendered archaeological approach. The data gathering for this research has been deliberately wide, and where gaps have been identified in the Irish evidence, comparative material from elsewhere has been considered. Nunneries should not be expected to conform to what has become the male monastic template of a claustrally-planned monastery. The research conducted shows a distinct and varied archaeology and architecture for medieval nunneries in Ireland which suggests that a claustral plan was not considered an essential part of a nunnery scheme. Nunneries provided an enclosed environment where women, for a variety of motives could become brides of Christ. Through the performance and celebration of the daily Divine Office, the Mass and seasonal liturgy, spaces used by the nunnery community were negotiated and transformed into a sacred Paradise on earth. However, rather than being isolated in the landscape nunneries in later medieval Ireland were located either within or close to walled towns, larger unenclosed settlements and settlement clusters and would have been well known throughout their hinterlands. This research concludes that nunneries were an intrinsic part of the medieval monastic landscape in Ireland and an essential component of patrons’ portfolios of patronage, at a particularly local level, and where they interacted closely with their local community.

Uncomfortable 'truths' and the centenary anniversary of the 1916 Rising in Ireland

How to deal with uncomfortable ‘truths’ from the past has long posed problems for historians and politicians alike and this is exemplified by attempts to ‘deal with’ the centenary anniversary of the 1916 Easter Rising in Ireland. How do we recognise the revolutionary ‘heroes’ of the past and their contribution to the building of the new ‘nation’ state to which we may pledge allegiance, without exposing the contradictions inherent in the way that ‘nation’ state has transformed, subverted and indeed corrupted many of the ideas for which they fought? More controversially, how do we honour the actions of revolutionaries in the past which led to death and destruction in pursuance of a grand ideal, while at the same time condemning others today who claim to have been likewise engaged, using similar methods, during the recent ‘Troubles’ (1969-98 and counting)? Attempts by the Irish state to deal with the centenary seem to illustrate the point.

The Great Book of Ireland - Leabhar Mór na hÉireann

The Great Book of Ireland, Leabhar Mór na hÉireann, is an extraordinary modern vellum manuscript in a single volume which comprises the original work of 120 artists, 140 poets and nine composers. Produced in Dublin between 1989 and 1991, it has been acquired by University College Cork to be preserved in posterity on behalf of the Irish people. Conceived originally as a venture to create a saleable artefact which would help to fund the development plans of two arts organizations in Ireland, the original architects of the idea and editors of the end product were Theo Dorgan of Poetry Ireland and Gene Lambert of Clashganna Mills, with Eamonn Martin as business manager. Out of their initial meeting in March 1989 came the first tentative idea of producing an original artefact that would raise substantial funds for their charitable-status arts organizations, while at the same time being a venture worthwhile in itself. What was to emerge was a project of breath-taking ambition and scale – The Great Book of Ireland, Leabhar Mór na hÉireann, completed in 1991. Artists, poets, and composers were asked to contribute in their own medium what they believed represented their hopes, fears, dreams, or imaginings in the Ireland of that particular time, and which would have resonance in a thousand years - as the longevity of vellum allows. Each page of The Great Book is a unique artefact in itself, often multi-layered or palimpsestial in nature. The whole “united” in design by the work of the scribe, Denis Brown. This paper will describes the creation process of the book, its subsequent history, and future plans for the book at University College Cork.

A kingdom near lost: English military recovery in Ireland, 1600-03

Ireland was rarely a peaceful realm for Elizabeth I, but Hugh O’Neill, Earl of Tyrone and his allies brought the edifice of English power in Ireland to the brink of collapse. The war in Ireland at the end of the sixteenth century devoured money, lives and reputations at a prodigious rate. However seven years of Irish success ended when in 1600 the Queen appointed Charles Blount, Lord Mountjoy as Lord Deputy. Success replaced failure, but only after the new Lord Deputy transformed English strategy and rebuilt the army into an instrument fit for purpose.

Occurrence of OsHV-1 in Crassostrea gigas cultured in Ireland during an exceptionally warm summer. Selection of less susceptible oysters

The occurrence of OsHV-1, a herpes virus causing mass mortality in the Pacific oyster Crassostrea gigas was investigated with the aim to select individuals with different susceptibility to the infection. Naïve spat transferred to infected areas and juveniles currently being grown at those sites were analyzed using molecular and histology approaches. The survey period distinguishes itself by very warm temperatures reaching up to 3.5°C above the average. The virus was not detected in the virus free area although a spread of the disease could be expected due to high temperatures. Overall mortality, prevalence of infection and viral load was higher in spat confirming the higher susceptibility in early life stages. OsHV-1 and oyster mortality were detected in naïve spat after 15 days of cohabitation with infected animals. Although, infection was associated with mortality in spat, the high seawater temperatures could also be the direct cause of mortality at the warmest site. One stock of juveniles suffered an event of abnormal mortality that was significantly associated with OsHV-1 infection. Those animals were infected with a previously undescribed microvariant whereas the other stocks were infected with OsHV-1 μVar. Cell lesions due to the infection were observed by histology and true infections were corroborated by in situ hybridization. Survivors from the natural outbreak were exposed to OsHV-1 μVar by intramuscular injection and were compared to naïve animals. The survival rate in previously exposed animals was significantly higher than in naïve oysters. Results derived from this study allowed the selection of animals that might possess interesting characteristics for future analysis on OsHV-1 resistance.
