'Working away in that Grey Area...' A qualitative exploration of the challenges general practitioners experience when managing behavioural and psychological symptoms of dementia
(2017)
Jennings, Aisling A.; Foley, Tony; McHugh, Sheena M.; Browne, John P.; Bradley, Colin P.
Abstract:
Background: general practitioners (GPs) have identified the management of behavioural and psychological symptoms of dementia (BPSD) as a particularly challenging aspect of dementia care. However, there is a paucity of research on why GPs find BPSD challenging and how this influences the care they offer to their patients with dementia. Objectives: to establish the challenges GPs experience when managing BPSD; to explore how these challenges influence GPs’ management decisions; and to identify strategies for overcoming these challenges. Design: qualitative study of GPs experiences of managing BPSD. Methods: semi-structured interviews were conducted with 16 GPs in the Republic of Ireland. GPs were purposively recruited to include participants with differing levels of experience caring for people with BPSD in nursing homes and in community settings to provide maximum diversity of views. Interviews were analysed thematically. Results: three main challenges of managing BPSD were identifie...

Abstract:
Background: Suicide accounts for over 58,000 deaths in Europe per annum, where suicide attempts are estimated to be 20 times higher. Males have been found to have a disproportionately lower rate of suicide attempts and an excessively higher rate of suicides compared to females. The gender difference in suicide intent is postulated to contribute towards this gender imbalance. The aim of this study is to explore gender differences in suicide intent in a cross-national study of suicide attempts. The secondary aims are to investigate the gender differences in suicide attempt across age and country. Methods: Data on suicide attempts (acquired from the EU-funded OSPI-Europe project) was obtained from eight regions in Germany, Hungary, Ireland and Portugal. Suicide intent data was categorized into 'Non-habitual Deliberate Self-Harm' (DSH), 'Parasuicidal Pause' (SP), 'Parasuicidal Gesture' (SG), and 'Serious Suicide Attempt' (SSA), applying the Feuerl...

A further analysis of the role of heterogeneity in coevolutionary spatial games
(2018)
Cardinot, Marcos; Griffith, Josephine; O'Riordan, Colm
Abstract:
Heterogeneity has been studied as one of the most common explanations of the puzzle of cooperation in social dilemmas. A large number of papers have been published discussing the effects of increasing heterogeneity in structured populations of agents, where it has been established that heterogeneity may favour cooperative behaviour if it supports agents to locally coordinate their strategies. In this paper, assuming an existing model of a heterogeneous weighted network, we aim to further this analysis by exploring the relationship (if any) between heterogeneity and cooperation. We adopt a weighted network which is fully populated by agents playing both the Prisoner’s Dilemma or the Optional Prisoner’s Dilemma games with coevolutionary rules, i.e., not only the strategies but also the link weights evolve over time. Surprisingly, results show that the heterogeneity of link weights (states) on their own does not always promote cooperation; rather cooperation is actually favoured by the...

A global-local fretting analysis methodology and design study for the pressure armour layer of dynamic flexible marine risers
(2019)
O'Halloran, Sinéad; Connaire, Adrian D.; Harte, Annette M.; Leen, Sean B.
Abstract:
In this paper, a global-local fretting design methodology for the pressure armour layer of flexible marine risers is outlined. This includes global dynamic riser analysis, geometrical and analytical sub-models and local nub-groove contact finite element analysis. Furthermore, a fretting test rig is developed and utilised to quantify coefficient of friction and wear coefficient under representative nub-groove loading conditions. The combination of the global-local computational methodology and experimental characterisation of pressure armour wire material allows for the development of running condition fretting maps. This identifies design criteria for critical riser global curvatures that are associated with minimum number of cycles to failure. The design methodology presented in this paper is applied to a realistic riser design study, using extreme sea-state loading conditions. In this case study, the predicted pressure armour fretting fatigue lives are found to be in the same rang...

A multi-scale crystal plasticity model for cyclic plasticity and low-cycle fatigue in a precipitate-strengthened steel at elevated temperature
(2019)
Li, Dong-Feng; Barrett, Richard A.; O'Donoghue, Padraic E.; O'Dowd, Noel P.; Leen, Sean B.
Abstract:
In this paper, a multi-scale crystal plasticity model is presented for cyclic plasticity and low-cycle fatigue in a tempered martensite ferritic steel at elevated temperature. The model explicitly represents the geometry of grains, sub-grains and precipitates in the material, with strain gradient effects and kinematic hardening included in the crystal plasticity formulation. With the multiscale model, the cyclic behaviour at the sub-grain level is predicted with the effect of lath and precipitate sizes examined. A crystallographic, accumulated slip (strain) parameter, modulated by triaxiality, is implemented at the micro scale, to predict crack initiation in precipitate-strengthened laths. The predicted numbers of cycles to crack initiation agree well with experimental data. A strong dependence on the precipitate size is demonstrated, indicating a detrimental effect of coarsening of precipitates on fatigue at elevated temperature. (C) 2016 Elsevier Ltd.

A physically-based high temperature yield strength model for 9Cr steels
(2019)
Barrett, Richard A.; O'Donoghue, Padraic E.; Leen, Sean B.
Abstract:
The strength of 9Cr steels, which is controlled by chemical composition and microstructure, evolves significantly under high temperature loading. This paper presents a temperature-independent, physically-based model for evolving yield strength, including the interdependent effects of dislocations, solutes, precipitates and grain boundaries. The key roles of solute and precipitate strengthening in 9Cr steels are successfully demonstrated. The measured significant beneficial effect of up to 3 wt% tungsten on solute strengthening, and hence, yield strength are successfully predicted. The new model demonstrates that the reported strength reduction in 9Cr-3W alloys under thermal aging can be primarily attributed to Laves phase formation and associated depletion of tungsten solutes, consistent with microstructural observations.

Abstract:
Journal article
Tidal turbine blades experience significant fatigue cycles during operation and it is expected that fatigue strength will be a major consideration in their design. Glass fibre reinforced polymers are a candidate low-cost material for this application. This article presents a methodology for preliminary fatigue design of glass fibre reinforced polymer tidal turbine blades. The methodology combines: (a) a hydrodynamic model for calculation of local distributions of fluid-blade forces; (b) a finite element structural model for prediction of blade strain distributions; (c) a fatigue damage accumulation model, which incorporates mean stress effects; and (d) uniaxial fatigue testing of two candidate glass fibre reinforced polymer materials (for illustrative purposes). The methodology is applied here for the preliminary design of a three-bladed tidal turbine concept, including tower shadow effects, and comparative assessment of pitch-and stall-regulated control with res...

Abstract:
A bipolar hold-down voltage was used to study mechanical degradation in radio-frequency microelectromechanical capacitive shunt switches. The bipolar signal was used to prevent the occurrence of dielectric charging and to isolate mechanical effects. The characteristics of material stress relaxation and recovery were monitored by recording the change of the pull-in voltage of a device. The creep effect in movable components was saturated by repeated actuation to the pulled-in position, while comparison with a theoretical model confirmed the presence of linear viscoelasticity in the devices.

Actively controllable topological phase transition in phononic beam systems
(2020)
Zhou, Weijian; Chen, Weiqiu; Destrade, Michel; Lim, C.W.
Abstract:
Topological insulators, which allow edge or interface waves but forbid bulk waves, have revolutionized our scientific cognition of acoustic/elastic systems. Due to their nontrivial topological characteristics, edge (interface) waves are topologically protected against defects and disorders. This superior and unique characteristic could lead to a wealth of new opportunities in applications of quantum and acoustic/elastic information processing. However, current acoustic/elastic topological insulators are still at an infancy stage where the theory and prediction only work in laboratories and there are still many problems left open before promoting their practical applications. One of the apparent disadvantages is their narrow working frequency range, which is the main concern in this paper. We design a one-dimensional phononic beam system made of a homogeneous epoxy central beam sandwiched by two homogeneous piezoelectric beams, and covered with extremely thin electrodes, periodically...

Messam, Locksley L. McV.; Kass, Philip H.; Chomel, BB; Hart, Lynette A.
Abstract:
This retrospective cohort study was aimed at describing the effects of age at acquisition, age, and duration of ownership of dogs on the risk of (1) bites during play and (2) non-play bites to humans. Data were collected on 110 dogs that had bitten during play with a person, 161 dogs that had bitten outside of play and 951 non-biting dogs from veterinary clients in Kingston (KGN), Jamaica and San Francisco (SF), USA. Modified Poisson regression was employed to model the relationships of both types of bites to each variable separately. Effects of the variables on dog bite risk (1) during and (2) outside of play with the dog, differed from each other and by type of bite. Effects varied with the dog's age and age-related associations were strongest in dogs younger than 1 year old. Ages at acquisition of dogs at highest risk for bites during play were substantially lower than those at risk for non-play bites. Ages and durations of ownership of dogs at highest risk for bites during ...

An Exploratory Study of the Role an Equine- Assisted Learning Programme plays in Diverting Young People from Criminal Pathways
(2015)
O'Kelly, Francisca
Abstract:
Interest in the potential of equine-assisted therapy and learning, where horses are incorporated in therapeutic, rehabilitative and educational interventions to ameliorate emotional, behavioural and social issues, has increased in the past half century. More recently, equine-assisted therapy and learning has been utilised in social work and penal contexts, such as in the rehabilitation and support of at-risk youth and young prisoners. However, there is a dearth of empirical research and published evaluative studies examining the effectiveness of these emerging programmes. The purpose of this study is to explore the role that a Dublin-based equine-assisted learning programme plays in diverting young people from criminal pathways. The perceived impact and personal experiences of participants participating in the equine-assisted learning programme are explored using a qualitative research approach. The findings that emerged from the study indicate that the development of empathy, self-...

Abstract:
The current study investigated comorbidity in eighty-nine children and adolescents with Autism Spectrum Disorder in Ireland. Comorbidity is the presence of one or more disorders in addition to a primary disorder. The prevalence of comorbid psychological disorders, behaviours associated with comorbid psychopathology, epilepsy, gastrointestinal symptoms and sleep problems were examined. Age, gender, level of intellectual disability, presence of epilepsy, attention deficit/hyperactivity disorder (AD/HD) and an anxiety disorder were determined using a self-constructed demographic questionnaire. The Autism Spectrum Disorder-Comorbidity-Child (ASD-CC) was administered to informants to assess symptoms of psychopathology and emotional difficulties. The Children's Sleep Habits Questionnaire (CSHQ) and Gastrointestinal Symptom Inventory were administered to assess sleep problems and gastrointestinal symptoms respectively. Forty-six percent of participants had a comorbid disorder, with th...

Appraising stone column settlement prediction methods using finite element analyses
(2017)
Sexton, Brian G.; McCabe, Bryan A.; Castro, Jorge
Abstract:
Numerous approaches exist for the prediction of the settlement improvement offered by the vibro-replacement technique in weak or marginal soil deposits. The majority of the settlement prediction methods are based on the unit cell assumption, with a small number based on plane strain or homogenisation techniques. In this paper, a comprehensive review and assessment of the more popular settlement prediction methods is carried out with a view to establishing which method(s) is/are in best agreement with finite element predictions from a series of PLAXIS 2D axisymmetric analyses on an end-bearing column. The Hardening Soil Model in PLAXIS 2D has been used to model the behaviour of both the granular column material and the treated soft clay soil. This study has shown that purely elastic settlement prediction methods overestimate the settlement improvement for large modular ratios, while the methods based on elastic-plastic theory are in better agreement with finite element predictions at...

Abstract:
Journal article
Water circulation patterns and associated material transport within a highly dynamic system such as the Irish Sea are complex phenomena. Although Tc-99 monitoring programme undertaken by the Radiological Protection Institute of Ireland provides a good insight to the material distribution on the east coast of Ireland, transport patterns within the Irish Sea have not been fully explored. In this study a validated transport model was used to hindcast transport of Tc-99 discharged from the Sellafield plant to determine extents of Tc-99 migration within the Irish Sea and reassess transit times to east coast of Ireland. Transit times are also estimated within a context of changes in meteorological conditions and fluctuations in discharges. Additionally, seasonal and inter-annual circulation patterns were examined.Relationships between discharge times and timing of far field concentrations are highly variable and are dependant on sea dynamics controlling the accumulatio...

Abstract:
Recent models of impaired awareness in brain injury draw a distinction between metacognitive knowledge of difficulties and online awareness of errors (emergent and anticipatory). We examined performance of 31 Traumatic Brain Injury (TBI) participants and 31 healthy controls using a three-strand approach to assessing awareness. Metacognitive knowledge was assessed with an awareness interview and discrepancy scores on three questionnaires?Patient Competency Rating Scale, Frontal Systems Behavioral Scale and the Cognitive Failures Questionnaire. Online Emergent Awareness was assessed using an online error-monitoring task while participants performed tasks of sustained attention. Online anticipatory awareness was examined using prediction performance on two cognitive tasks. Results indicated that the TBI Low Self-Awareness (SA) group and High SA group did not differ in terms of severity, chronicity or standard neuropsychological tasks but those with Low SA were more likely to exhibit di...

Abstract:
Background: Cardiovascular disease (CVD) is the leading cause of premature death and disability in Europe, accounting for 4 million deaths per year and costing the European Union economy almost €196 billion annually. There is strong evidence to suggest that exercise-based secondary rehabilitation programs can decrease the mortality risk and improve health among patients with CVD. Theory-informed use of behavior change techniques (BCTs) is important in the design of cardiac rehabilitation programs aimed at changing cardiovascular risk factors. Electronic health (eHealth) is the use of information and communication technologies (ICTs) for health. This emerging area of health care has the ability to enhance self-management of chronic disease by making health care more accessible, affordable, and available to the public. However, evidence-based information on the use of BCTs in eHealth interventions is limited, and particularly so, for individuals living with CVD. Objective: The aim of ...

Bimodular rubber buckles early in bending
(2013)
Destrade, Michel; Gilchrist, Michael D.; Motherway, Julie A.
Abstract:
A block of rubber eventually buckles under severe flexure, and several axial wrinkles appear on the inner curved face of the bent block. Experimental measurements reveal that the buckling occurs earlier - at lower compressive strains - than expected from theoretical predictions. This paper shows that if rubber is modeled as being bimodular, and specifically, as being stiffer in compression than in tension, then flexure bifurcation happens indeed at lower levels of compressive strain than predicted by previous investigations (these included taking into account finite size effects, compressibility effects, and strain-stiffening effects). Here the effect of bimodularity is investigated within the theory of incremental buckling, and bifurcation equations, numerical methods, dispersion curves, and field variations are presented and discussed. It is also seen that Finite Element Analysis software seems to be unable to encompass in a realistic manner the phenomenon of bending instability f...

Abstract:
Purpose - This study aims to examine the relationship between social influence and consumers' self-expression through brands. It considers susceptibility to interpersonal influence and social network influence on self-expressive brands and brand tribalism. The study examines whether self-expressive brands and brand tribalism influence brand loyalty and word of mouth (WOM).Design/methodology/approach - A cross-sectional online survey was carried out with members of Generation Y in Ireland. Data from 675 complete responses were analysed using SPSS 20 and AMOS 20. A structural model tested nine hypothesised relationships.Findings - Findings indicate that both online social network influence and susceptibility to interpersonal influence are antecedents of tribalism and self-expressive brands. Consumers of self-expressive brands are loyal and offer positive WOM. By contrast, those who seek tribal membership have less brand loyalty and offer less WOM than other consumers. Findings su...

Changes in the immune system in rodent models of depression
(2018)
Leonard, Brian E.; Song, Cai
Abstract:
This review summarizes some of the evidence which implicates an increase in the peripheral and central secretion of pro-inflammatory cytokines in the behavioural changes seen in some stress-induced and brain lesion models of depression. Following a consideration of the role of cytokines in the periphery and the brain, evidence is presented suggesting that pro-inflammatory cytokines alter the function of monoamine neurotransmitters which have been implicated in severe stress and in major depression. These changes occur in the presence of elevated glucocorticoid concentrations which suggests that immune activation is correlated with a decrease in the sensitivity of the glucocorticoid receptors on immune cells in addition to those occurring in the brain, The review concludes with a brief account of the various rodent models of depression in which evidence of immune activation as been demonstrated.
