A New Mechanism for Mode Water Formation involving Cabbeling and Frontogenetic Strain at Thermohaline Fronts. Part II: Numerical simulations

Submesoscale-resolving numerical simulations are used to investigate a mechanism for sustained mode water formation via cabbeling at thermohaline fronts subject to a confluent strain flow. The simulations serve to further elucidate the mechanism and refine the predictions of the analytical model of Thomas and Shakespeare (2015). Unlike other proposed mechanisms involving air-sea fluxes, the cabbeling mechanism, in addition to driving significant mode water formation, uniquely determines the thermohaline properties of the mode water given knowledge of the source water masses on either side of the front. The process of mode water formation in the simulations is as follows. Confluent flow associated with idealised mesoscale eddies forces water horizontally towards the front. The frontogenetic circulation draws this water near-adiabatically from the full-depth of the thermohaline front up to the surface 25 meters, where resolved submesoscale instabilities drive intense mixing across the thermohaline front, creating the mode water. The mode water is denser than the surrounding stratified fluid and sinks to fill its neutral buoyancy layer at depth. This layer gradually expands up to the surface and eddies composed entirely of this mode water detach from the front and accumulate in the difluent regions of the domain. The process continues until the source water masses are exhausted. The T-S relation of the resulting mode water is biased to the properties of the source water that has the larger isopycnal T-S anomaly. This mechanism has the potential to drive O(1 Sv) mode water formation, and may be important in determining the properties of mode water in the global oceans.L. N.

Moral wrongs, disadvantages, and disability: a critique of critical disability studies

Critical disability studies (CDS) has emerged as an approach to the study of disability over the last decade or so and has sought to present a challenge to the predominantly materialist line found in the more conventional disability studies approaches. In much the same way that the original development of the social model resulted in a necessary correction to the overly individualized accounts of disability that prevailed in much of the interpretive accounts which then dominated medical sociology, so too has CDS challenged the materialist line of disability studies. In this paper we review the ideas behind this development and analyse and critique some of its key ideas. The paper starts with a brief overview of the main theorists and approaches contained within CDS and then moves on to normative issues; namely, to the ethical and political applicability of CDS

Digital Education and Training Inventory

As the construction industry continues to evolve and increasingly embraces digitisation, an early-stage deliverable for Build Digital Project was to conduct a horizon scan of the opportunities available for those within the construction sector. A primary aim, therefore, is to provide a comprehensive inventory of educational and training provisions that exist within Ireland at present. The resulting searchable inventory focuses on key educational sectors including Universities, Educational Training Boards (ETBS), Colleges of Further Education, Professional bodies and similar organisations

Needs or rights? A challenge to the discourse of special education

It is nearly 30 years since Mary Warnock's Report of the Committee of Enquiry into the Education of Handicapped Children and Young People introduced the phrase ‘special educational needs’ into the UK education system. In this article, Katherine Runswick-Cole, Research Associate at Manchester Metropolitan University, and Nick Hodge, Principal Lecturer in Research Development at Sheffield Hallam University, argue for the abandonment of the ‘special needs’ discourse, claiming that it has, in fact, led to exclusionary practices within education. Building on the work of early years educators in Reggio Emilia schools in Northern Italy, the authors advocate for the adoption of the phrase ‘educational rights’ and suggest that the positive impact of such a linguistic turn would be significant for the lives of young people currently described as having ‘special educational needs’ and for children's rights

Phase Evolution and Li Diffusion in LATP Solid-State Electrolyte Synthesized via a Direct Heat-Cycling Method

Herein, the direct synthesis of phase-pure lithium aluminum titanium phosphate (Li_{1.3}Al_{0.3}Ti_{1.7}(PO_{4})_{3}, LATP) solid-electrolyte powder in 220 min and relatively low temperatures (850 °C) is achieved via a new (cyclic) fast heat treatment (c-FHT) route. The complex structural evolution highlights rate-limited lithium incorporation of intermediate metal phosphates formed prior to the final phase-pure LATP. The prepared LATP product powder displays similar bulk (2 × 10^{−10} cm^{2} s^{−1}) and local (3 × 10^{−10} cm^{2} s^{−1}) values for lithium diffusion coefficients (D_{Li}) characterized by electrochemical impedance spectroscopy and muon spin relaxation (μSR), respectively. The similarity between both D_{Li} values suggests excellent retention of inter- and intraparticle lithium diffusion, which is attributed to the absence of deleterious surface impurities such as AlPO4. A low-energy barrier (E_{a} = 73 meV) of lithium diffusion is also estimated from the μSR data

'It's a Form of Freedom': The experiences of people with disabilities within equestrian sport

This paper explores the embodied, gendered experiences of disabled horse‐riders. Drawing on data from five in‐depth interviews with paradressage riders, the ways in which their involvement in elite disability sport impacts upon their sense of identity and confidence are explored, as well as the considerable health and social benefits that this involvement brings. Social models of disability are employed and the shortcomings of such models, when applied to disability sport, are highlighted. The data presented here demonstrates the necessity of seeing disability sport as an embodied experience and acknowledging the importance of impairment to the experiences of disabled athletes. Living within an impaired body is also a gendered experience and the implications of this when applied to elite disability sport are considered

Culture and carelessness: Constituting disability in South India

This is the author's accepted manuscript. The final published article is available from the link below.Professional and lay explanations of disability, collected via interviews and participant-observation during fieldwork in Hyderabad, South India, identify “carelessness” and “superstition” as major impediments to good health among the general population, and education as the key solution. In that such findings suggest a valorization of personal responsibility for self-care, the Foucauldian concept of biopower appeared a salient framework for analysis. Although illuminating, however, biopower was ultimately inadequate for explaining what emerged, on closer analysis, as significant discrepancies between assumptions about how disabled people engaged with healthcare services and their actual beliefs and practices; and between the moral interpretations different stakeholders made of “carelessness” in describing perceived causes of disability. My data also suggested that education was not in itself a key determinant in people's healthcare decisions. This article explores these differences between official and demotic discourses concerning the causes of disability and attempts to account for them ethnographically.The British Academ

Evaluating Lifeworld as an emancipatory methodology

Disability research is conducted within a highly politicised ‘hotbed’ of competing paradigms and principles. New researchers, who want to work within the social model, are soon faced with complex and challenging methodological and philosophical dilemmas. The social model advocates research agendas that are focused on the emancipation and empowerment of disabled people but, in reality, these are rarely achieved. To be successful researchers need to engage with innovative and creative methodologies and to share their experiences of these within environments that welcome challenge and debate. This paper focuses on Lifeworld and assesses its value as a tool for emancipatory research. Using examples from a study with parents, whose children were in the process of being labelled as having autism, the paper illustrates how the principles that ‘underpin’ the methodology offered a supportive framework for a novice researcher
