A multi-technology approach to identifying the reasons for lateral drift in professional and recreational darts

This work performs an extensive charterisation of precision targeted throwing in professional and recreational darts. The goal is to identify the contributing factors for lateral drift or throwing inaccuracy in the horizontal plane. A multitechnology approach is adopted whereby a custom built body area network of wireless inertial measurement devices monitor tilt, force and timing, an optical 3D motion capture system provides a complete kinematic model of the subject, electromyography sensors monitor muscle activation patterns and a force plate and pressure mat capture tactile pressure and force measurements. The study introduces the concept of constant throwing rhythm and highlights how landing errors in the horizontal plane can be attributable to a number of variations in arm force and speed, centre of gravity and the movements of some of the bodies non throw related extremities.

Capturing the overarm throw in darts employing wireless inertial measurement

This work employs a custom built body area network of wireless inertial measurement technology to conduct a biomechanical analysis of precision targeted throwing in competitive and recreational darts. The solution is shown to be capable of measuring key biomechanical factors including speed, acceleration and timing. These parameters are subsequently correlated with scoring performance to determine the affect each variable has on outcome. For validation purposes an optical 3D motion capture system provides a complete kinematic model of the subject and enables concurrent benchmarking of the 'gold standard' optical inertial measurement system with the more affordable and proactive wireless inertial measurement solution developed as part of this work.

Place, teenagers and urban identities: Growing up in the revanchist city

The recreational lives of teenagers in Ireland has been the subject of much debate in recent years. The subject has received much attention from academics, particularly in the UK and the US. In Ireland there is a dearth of research on, and a poor understanding of teenagers recreational lives. Additionally much of the research from the UK and the US to date has been focused on teenagers’ use of the street for recreation, arguing that teenagers are increasingly pushed out of public space. The research frequently emphasises teenagers’ resistance against adult hegemony. This thesis explores the recreational geographies of teenagers living in two socially and economically distinct neighbourhoods in Cork. It seeks to fill in gaps in knowledge of teenagers recreational lives in Ireland and contribute to geographical wisdom on teenagers’ geographies. Using a mixed method approach and a variety of thinking tools this research shows that teenagers living in Cork are growing up in a revanchist society. The thesis demonstrates how teenagers’ recreational practices are currently being configured in Irish society, unfolding strategies of dominance and affection which construct and regulate the recreational lives of teenagers. The effects of revanchism on teenagers’ experiences of outdoor space for recreation are also pursued. Furthermore the socio-spatial contingencies of teenagers’ recreational lives and revanchism are probed throughout the thesis, but in greater depth in the final chapters. The work also addresses an under-researched aspect of young people’s recreational - relationships with pets. Lastly, the subject of teenagers’ right to urban space is critically analysed.

Substance misuse in young people in Ireland - a focus on benzodiazepines

Benzodiazepines are a class of drugs that are prescribed for the treatment of anxiety and insomnia. Due to the powerful tolerance that can develop as a result of sustained use, benzodiazepines can also be dependence-forming. Benzodiazepine dependence can occur from prescribed and from recreational use, and is a significant issue for young people. The consequences of benzodiazepine dependence include cognitive and learning impairment, depressive symptoms, and increased suicide risk. Despite these risks, the nature of youth benzodiazepine use has not been explored to the same extent as other drugs. A review of existing Irish literature revealed that benzodiazepines are one of the five most recreationally-used drugs among young people. Analyses of young people attending a treatment centre indicated that young attendees from urban areas were more likely to be referred to the centre because of benzodiazepines than rural attendees. Further examination of the centre’s attendees showed that regular benzodiazepine users experienced more paranoia, loss of interest in sport, and pallor than non-regular users. Analysis of benzodiazepine prescribing to young people revealed that approximately one in seven young people were prescribed benzodiazepines for periods greater than recommended by national guidelines. Young benzodiazepine users discussed in interviews that they took benzodiazepines to escape from negative feelings and that they are generally taken in a social setting. Further interviews with youth counsellors and general practitioners highlighted that both family and community attitude to benzodiazepine use can impact on a young person’s benzodiazepine usage. Suggestions for reducing benzodiazepine use such as psychological alternatives to medication, public awareness campaigns and prescribing restrictions are provided. Future research can elaborate upon this work to determine other methods of reducing youth benzodiazepine use and the damage that it causes to the young people themselves, but also to their families, their community, and society at large.
