Topological fingerprints in Liouvillian gaps
No full textTopology in many-body physics usually emerges as a feature of equilibrium quantum states. We show that topological fingerprints can also appear in the relaxation rates of open quantum systems. To demonstrate this we consider one of the simplest models that has two topologically distinct phases in its ground state: the Kitaev chain model for th
Investigating the Roles of the N-Degron Pathway in Regulating the Crosstalk Between Hypoxia and the Innate Immune Responses.
No full textHow plants integrate and respond to multiple simultaneous or consecutive stresses is an increasingly pressing question with the advent of Climate Change. Presented in this Ph.D. thesis is an exploration of the crosstalk between hypoxia and immune responses and the role of the N-degron pathway in its regulation. Transcriptomic analyses using RNA-Seq facilitated dissection of Arabidopsis responses to combined hypoxia and flg22, uncovering interactions between responses to these stresses. It was discovered that hypoxia represses flg22-induced responses at the gene level and also dampens cellular immune responses (e.g. MAPK signalling and callose deposition). This work also found combined hypoxia/flg22 treatments induce novel responses which may point towards pathways that antagonise multi-stress resistance but also those which lie at the intersection of multiple stresses. One pathway which was particularly enriched under combined treatments was jasmonic acid (JA) signalling. The phytohormone JA is well known for its involvement in plant stress responses and this study further highlighted its role as a potential point of intersection for hypoxia and flg22 responses. Further, a potential role for the N-degron pathway in the removal of repression of JA signalling by the repressor protein, JASMONATE ZIM-DOMAIN 8 (JAZ8), was proposed by this work, with an N-degron pathway component, ARGINYL-TRANSFERASE 1 (ATE1), binding JAZ8 and mediating its destabilization. This further supports JA as a point of crosstalk between hypoxia and flg22 responses with the N-degron pathway potentially playing a regulatory role. Similar work to that in plants was attempted in mammals to allow direct comparison of conserved roles of the N-degron pathway in innate immunity and its role in the interplay between hypoxia and immunity. Aims to generate ATE1 knockout RAW264.7 macrophages were however unsuccessful, halting this work
Physical and perceptual demands of youth international team match-play in traditional and aged-matched future teams for biologically late maturing soccer players
No full textBackground: Given the rapidly increasing interest in national futures programmes, and the associated
significant increased resource investment, there is a pressing need for data specific to futures programmes
to inform practice across world football.
Aim: To investigate the differences in the physical and perceptual demands of match-play using Global
Positioning Software technology and Rating of Perceived Exertion (RPE) in traditional youth internation
team and age-matched international future teams for biologically late-maturing players over one
in-season period.
Subjects and methods: total of 18 U15 future team (FT) players and 21 national team (NT) playe
were examined.
Results: The results showed that FT players performed 9% greater total distances (p=0.008, Cohen’s d
1.29) and accumulated 20% greater total player loads (p<0.001, Cohen’s d 1.88) than NT players durin
matches. In contrast, NT players covered 113% greater sprinting distances (p=0.033, Cohen’s d 0.63) a
performed 62% more high-intensity accelerations (p=0.015, Cohen’s d 0.90) than FT players. There were
no differences in high-intensity and very high-intensity running distances, number of accelerations,
number of decelerations or high-intensity decelerations, or match-play RPE. When accounting for
biological maturation, the adjusted marginal means were not different between FT and NT players in
any physical metric except for total player load (p=0.046) and high-intensity accelerations (p<0.030).
Conclusion: We conclude that while several physical performance metrics differ significantly between FT
and NT match-play, the most robust differences after controlling for maturation are in sprint performance
and high-intensity accelerations
Making MACMORRIS: New Gleanings from Early Modern Ireland
No full textI am extremely grateful to Dr Lizzie Boyle and to my colleagues
in Sean- agus Nua-Ghaeilge for the invitation to give the Paul
Walsh Memorial Lecture (2022), not least because it allowed me
to pay my respects to someone whose scholarly company I kept at
different stages during my D. Phil. – and someone on whose
scholarship I still draw. Yellowed sheaves of hand-written notes
bring me back to the Bodleian Library when it not only permitted
notetaking in ink but actively fed the habit by providing bottles of
blue and black – and blue-black – Quink in a blotter-littered hatch
by the issue desk. Those notes catch me in the act of scouring
Walsh’s Gleanings from Irish Manuscripts, Irish Men of
Learning, Irish Chiefs and Leaders, and his editions of Ó
Cianáin’s Imeacht na n-Iarlaí and Ó Cléirigh’s Beatha Aodha
Ruaidh. They bring back the physicality – and frustrations – of
bibliographical searches in a time before online catalogues:
hoiking an enormous, alphabetically ordered catalogue (Va-Wap)
onto a shelf and trawling through pasted-in, ‘movable-slip’
entries, to track down the scattered essays which Nollaig Ó
Muraíle subsequently brought together in Learning through the
Ages

Climate change made the extreme 2-day rainfall event associated with flooding in Midleton, Ireland more likely and more intense
No full textOn the 17th and 18th October 2023, Storm Babet brought record rainfall amounts to the south
of Ireland leading to significant flooding, with the town of Midleton, County Cork severely
impacted. The intense 2-day rainfall fell on soils saturated by over 3 months of above average
rainfall.
The study, which involved ICARUS along with the World Weather Attribution (WWA) team based in Imperial College London and Met Eireann and was carried out for RTÉ, found that the extreme rainfall that occurred over two days had “an increased intensity of around 13% due to global warming
Illusions of online readiness: the counter-intuitive impact of rapid immersion in digital learning due to COVID-19
No full textFramed from a socio-cognitive perspective, and the contemporary increased salience of digital learning readiness and competence, the purpose of this study was two-fold: to validate Online Learner Readiness Scale in a new context and to explore potential variances in online readiness within a student-teacher population between less (pre-COVID) and more experienced (during COVID) groups. A CFA was used to examine the suitability of the OLRS in an Irish context, and variances between groups based on gender and professional experience were explored. Two cross-sectional datasets were gathered from student teachers from a university teacher education programme in the Republic of Ireland (n1 = 281, n2 = 154). The analysis demonstrated significantly lower perceived online readiness in the more experienced ‘during COVID’ cohort compared to ‘pre-COVID’ cohort. This counter-intuitive finding is in direct contrast to prior research, and potential influencing factors include the sudden immersion in an entirely digital learning environment. The more experienced cohort reported significantly lower online readiness across all five components of the OLRS. The findings are discussed in the context of a major shift in the student-teacher learning experience due to COVID-19. Implications for future research are explored in the context of increasingly digitised teaching and learning environments during and after the COVID-19 pandemic
‘We are always planning trips to Poland’: the influence of transnational family life on the family language policy of Polish-speaking families in Ireland
No full textIn the context of heightened global transnational movements and the proximate geographical positioning of Poland and Ireland, this study investigates the impact of the transnational nature of Polish families’ migration experiences in The Republic of Ireland on their family language policy. This research endeavours to address a gap in the literature surrounding the influence of transnationalism on family language policy within Polish-speaking migrant families in Ireland. Grounded in Curdt-Christiansen's [Curdt-Christiansen, X. L. 2018. “Family Language Policy.” In Oxford Handbook of Language Policy and Planning, edited by J. W. Tollefson and M. Pérez-Milans. New York: Oxford University Press.] interdisciplinary model of family language policy, this investigation draws on an ethnographic inquiry into three Polish-speaking families in Ireland. The study focuses on families with first- and second-generation migrant children. Data were gathered through a combination of semi-structured interviews and children's reflective language diaries. The results depict the transnational nature of family life, with recurrent travel between Ireland and Poland evident across all three families. To sustain connections with Poland, parents implemented specific language management strategies. The study underscored the participants’ recognition of the interdependence between the use of the Polish language and the continuation of connections with Poland, as well as the capacity to uphold family life across Ireland and Poland
Researching the far right: towards an ethics of talking ‘about’
No full textThe far right, under its many names and guises, has become a hugely popular area of research within political science and other disciplines (Gattinara, 2020; Carter, 2018). Despite such sustained interest, and scant evidence to suggest that it is waning, this attention has certainly not been matched by levels of engagement with the specific ethical implications of researching the far right. With the way that academia can contribute to the political dynamics for which it offers interpretations, there is an urgent need to deal with these questions and reflect on our practices at every stage of the research process
