Predicting subsequent task performance from goal motivation and goal failure

Recent research has demonstrated that the cognitive processes associated with goal pursuit can continue to interfere with unrelated tasks when a goal is unfulfilled. Drawing from the self-regulation and goal-striving literatures, the present study explored the impact of goal failure on subsequent cognitive and physical task performance. Furthermore, we examined if the autonomous or controlled motivation underpinning goal striving moderates the responses to goal failure. Athletes (75 male, 59 female, Mage = 19.90 years, SDage = 3.50) completed a cycling trial with the goal of covering a given distance in 8 min. Prior to the trial, their motivation was primed using a video. During the trial they were provided with manipulated performance feedback, thus creating conditions of goal success or failure. No differences emerged in the responses to goal failure between the primed motivation or performance feedback conditions. We make recommendations for future research into how individuals can deal with failure in goal striving

Factors affecting nitrate distribution in shallow groundwater under a beef farm in South Eastern Ireland

peer-reviewedGroundwater contamination was characterised using a methodology which combines shallow groundwater geochemistry data from 17 piezometers over a 2 yr period in a statistical framework and hydrogeological techniques. Nitrate–N (NO3-N) contaminant mass flux was calculated across three control planes (rows of piezometers) in six isolated plots. Results showed natural attenuation occurs on site although the method does not directly differentiate between dilution and denitrification. It was further investigated whether NO3-N concentration in shallow groundwater (<5 m below ground level) generated from an agricultural point source on a 4.2 ha site on a beef farm in SE Ireland could be predicted from saturated hydraulic conductivity (Ksat) measurements, ground elevation (m Above Ordnance Datum), elevation of groundwater sampling (screen opening interval) (m AOD) and distance from a dirty water point pollution source. Tobit regression, using a background concentration threshold of 2.6 mg NO3-N L−1 showed, when assessed individually in a step wise procedure, Ksat was significantly related to groundwater NO3-N concentration. Distance of the point dirty water pollution source becomes significant when included with Ksat in the model. The model relationships show areas with higher Ksat values have less time for denitrification to occur, whereas lower Ksat values allow denitrification to occur. Areas with higher permeability transport greater NO3-N fluxes to ground and surface waters. When the distribution of Cl− was examined by the model, Ksat and ground elevation had the most explanatory power but Ksat was not significant pointing to dilution having an effect. Areas with low NO3 concentration and unaffected Cl− concentration points to denitrification, low NO3 concentration and low Cl− chloride concentration points to dilution and combining these findings allows areas of denitrification and dilution to be inferred. The effect of denitrification is further supported as mean groundwater NO3-N was significantly (P < 0.05) related to groundwater N2/Ar ratio, redox potential (Eh), dissolved O2 and N2 and was close to being significant with N2O (P = 0.08). Calculating contaminant mass flux across more than one control plane is a useful tool to monitor natural attenuation. This tool allows the identification of hot spot areas where intervention other than natural attenuation may be needed to protect receptors.Research Stimulus Fund, Department of Agriculture Fisheries and Food (Ireland

Exploring the Use of Numerical Relativity Waveforms in Burst Analysis of Precessing Black Hole Mergers

Recent years have witnessed tremendous progress in numerical relativity and an ever improving performance of ground-based interferometric gravitational wave detectors. In preparation for Advanced LIGO and a new era in gravitational wave astronomy, the numerical relativity and gravitational wave data analysis communities are collaborating to ascertain the most useful role for numerical relativity waveforms in the detection and characterization of binary black hole coalescences. In this paper, we explore the detectability of equal mass, merging black hole binaries with precessing spins and total mass M_T in [80,350]Msol, using numerical relativity waveforms and template-less search algorithms designed for gravitational wave bursts. In particular, we present a systematic study using waveforms produced by the MAYAKRANC code that are added to colored, Gaussian noise and analyzed with the Omega burst search algorithm. Detection efficiency is weighed against the orientation of one of the black-hole's spin axes. We find a strong correlation between the detection efficiency and the radiated energy and angular momentum, and that the inclusion of the l=2, m=+/-1,0 modes, at a minimum, is necessary to account for the full dynamics of precessing systems.Comment: 9 pages, 15 figure

The letters: a novel

This work is in two parts: a historical fiction novel, The Letters, and a supporting essay, Fictionalising History. The novel tells the story of Sister Patricia, an Irish nun and missionary, as she arrives back in Ireland. Upon her return, Sister Patricia is confronted by a box of letters and through them she must face her past, in particular the events of November 1920, when her brothers, Patrick and Harry Loughnane, were murdered during the Irish War of Independence. The Letters explores memory, religion, storytelling and the supernatural, thinking about how our past shapes the people we become and how we process trauma. It is a novel about the aftermath of war, from a female perspective, and it is based on real life events. The essay is divided into four chapters: Research, Writing, Editing and Final Thoughts. It assesses the problems and benefits of too much information and considers what is more important, fact or fiction? To do this it analyses the process of research and writing, establishing setting and voice, as well as creating narrative tension. It explores the themes of the novel and looks at the way we tell stories and how reliable they are when told from memory and how that affects the retelling of history. In summary, it dissects the creative process of writing a historical novel and discusses how historical accuracy sometimes has to change for the sake of fiction. Throughout the essay, ideas are supported by the work of authors, writing about Ireland or Ghana, or in the historical fiction genre, namely, Sebastian Barry, Anne Enright, Toni Morrisson, Emer Martin and Seamus Deane

Motivation and goal self-regulation

The present thesis extends the goal striving literature by exploring personal and primed autonomous and controlled goal motivation in relation to goal-related outcomes (e.g. persistence, attainment, inter-goal relations), the responses to goal failure, and well- and ill-being. Aligned with the Self-Concordance (SC) Model (Sheldon & Elliot, 1999), the central hypothesis was that autonomous motives would be associated with more adaptive goal pursuit and higher well-being. We investigated this hypothesis within a sporting context. In Chapter 2, we used ecologically valid video primes to manipulate goal motives. Extending the previous literature, we demonstrated that primed autonomous motives were associated with higher objectively assessed persistence towards an increasingly difficult goal than primed controlled motives. Chapter 3 showed that primed goal motives did not moderate the responses to goal failure. However we presented recommendations for how future research can investigate how individuals react to goal failure. Within Chapter 4, we blended the SC model with the Hierarchical Model of Motivation (Vallerand, 1997) to explain how coach behaviour can facilitate adaptive goal striving and well-being in team-sport athletes. Finally, Chapter 5 used a person-centred approach to examine autonomous and controlled goal motives when pursuing goals in multiple domains. The results suggested that higher autonomous motives are important for adaptive facilitation between goals. The research presented within this thesis represents important conceptual advancements of the goal striving literature. Furthermore, we present important practical implications for those engaging in goal pursuit in sport. Overall, we demonstrate the importance of individuals striving for goals which are underpinning by autonomous goal motives

Effectiveness and safety of orally administered immunotherapy for food allergies: a systematic review and meta-analysis

The aim of using oral and sublingual immunotherapy with food allergies is to enable the safe consumption of foods containing these aller- gens in patients with food allergies. In the present study, a systematic review of intervention studies was undertaken; this involved the searching of eleven international databases for controlled clinical trials. We identified 1152 potentially relevant papers, from which we selected twenty-two reports of twenty-one eligible trials (i.e. eighteen randomised controlled trials and three controlled clinical trials). The meta-analysis revealed a substantially lower risk of reactions to the relevant food allergen in those receiving orally administered immu- notherapy (risk ratios (RR) 0·21, 95 % CI 0·12, 0·38). The meta-analysis of immunological data demonstrated that skin prick test responses to the relevant food allergen significantly decreased with immunotherapy (mean difference 2 2·96 mm, 95 % CI 2 4·48, 2 1·45), while aller- gen-specific IgG4 levels increased by an average of 19·9 (95 % CI 17·1, 22·6) m g/ml. Sensitivity analyses excluding studies at the highest risk of bias and subgroup analyses in relation to specific food allergens and treatment approaches generated comparable summary estimates of effectiveness and immunological changes. Pooling of the safety data revealed an increased risk of local (i.e. minor oropharyngeal/gastro- intestinal) adverse reactions with immunotherapy (RR 1·47, 95 % CI 1·11, 1·95); there was a non-significant increased average risk of systemic adverse reactions with immunotherapy (RR 1·08, 95 % CI 0·97, 1·19). There is strong evidence that orally administered immu- notherapy can induce immunomodulatory changes and thereby promote desensitisation to a range of foods. However, given the paucity of evidence on longer-term safety, effectiveness and cost-effectiveness, orally administered immunotherapy should not be used outside experimental conditions presently

Staff Training in Intellectual and Developmental Disability Settings: a Scoping Review

© 2019, Springer Science+Business Media, LLC, part of Springer Nature. Frontline staff are a valuable asset within an intellectual and developmental disability service. Their work dictates the overall standard of care delivered by the organization. However, there is evidence that the research relating to effective practice is having little impact on the competencies displayed by staff in the real-world setting. Therefore, a scoping review of published literature was conducted to investigate potential explanations for the inadequate dissemination of evidence-based practice in this sector. Systematic searches of relevant databases identified 156 papers for inclusion in the review. Practices in which staff were trained were categorized as either behavioral interventions or “other” interventions. The behavioral category was sub-divided into: a) assessment; b) antecedent; c) consequence and, d) “mixed” practices. Although the studies reviewed provided staff training across a range of practices, many empirically supported interventions were not utilized. Despite rigorous scientific support for strategies such as functional communication training and noncontingent reinforcement, the literature did not robustly evaluate effective protocols to disseminate these practices to frontline staff. The review also highlighted a continued reliance on individualized training packages, rather than the implementation of empirically supported training models. Finally, results showed that a relatively small number of included studies examined the impact of staff training on service user outcomes and adult service users were underrepresented across all intervention categories. Findings provide a potential explanation for the apparent disconnect between theoretical advancements and practice in the applied setting and are discussed in relation to approaches to staff training

Biomolecules from Macroalgae-Nutritional Profile and Bioactives for Novel Food Product Development

Seaweed is in the spotlight as a promising source of nutrition for humans as the search for sustainable food production systems continues. Seaweed has a well-documented rich nutritional profile containing compounds such as polyphenols, carotenoids and polysaccharides as well as proteins, fatty acids and minerals. Seaweed processing for the extraction of functional ingredients such as alginate, agar, and carrageenan is well-established. Novel pretreatments such as ultrasound assisted extraction or high-pressure processing can be incorporated to more efficiently extract these targeted ingredients. The scope of products that can be created using seaweed are wide ranging: from bread and noodles to yoghurt and milk and even as an ingredient to enhance the nutritional profile and stability of meat products. There are opportunities for food producers in this area to develop novel food products using seaweed. This review paper discusses the unique properties of seaweed as a food, the processes involved in seaweed aquaculture, and the products that can be developed from this marine biomass. Challenges facing the industry such as consumer hesitation around seaweed products, the safety of seaweed, and processing hurdles will also be discussed
