Precision biomechanical motion tracking and throw characterisation in professional darts

In professional sports there are in general three steps required to improve performance namely task definition, training and performance assessment. This process is iteratively repeated and feedback generated from quantitative performance measurement is in turn used for task redefinition. Task definition can be achieved in a number of ways including via video streaming or indeed and as is more common, by listening to coaching staff. However non-subjective performance evaluation is difficult due to the complexity of the movements involved. When considering the subset of sports where precision accuracy and repeatability are a necessity this problem becomes inherently more difficult to solve. Until recently sports such as martial arts, fencing and darts, where the smallest deviation from a prescribed movement goal can result in large outcome error, were deemed too difficult to characterise fully. Advances in technology, as illustrated by this study, now make this type of physiometry possible.

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.

An automated calibration tool for high performance wireless inertial measurement in professional sports

Traditional motion capture techniques, for instance, those employing optical technology, have long been used in the area of rehabilitation, sports medicine and performance analysis, where accurately capturing bio-mechanical data is of crucial importance. However their size, cost, complexity and lack of portability mean that their use is often impractical. Low cost MEMS inertial sensors when combined and assembled into a Wireless Inertial Measurement Unit (WIMU) present a possible solution for low cost and highly portable motion capture. However due to the large variability inherent to MEMS sensors, such a system would need extensive characterization to calibrate each sensor and ensure good quality data capture. A completely calibrated WIMU system would allow for motion capture in a wider range of real-world, non-laboratory based applications. Calibration can be a complex task, particularly for newer, multi-sensing range capable inertial sensors. As such we present an automated system for quickly and easily calibrating inertial sensors in a packaged WIMU, demonstrating some of the improvements in accuracy attainable.

A preliminary study on how fatigue affects scoring average in professional darts

The purpose of this preliminary study is to identify signs of fatigue in specific muscle groups that in turn directly influence accuracy in professional darts. Electromyography (EMG) sensors are employed to monitor the electrical activity produced by skeletal muscles of the trunk and upper limb during throw. It is noted that the Flexor Pollicis Brevis muscle which controls the critical release action during throw shows signs of fatigue. This is accompanied by an inherent increase in mean integral EMG amplitude for a number of other throw related muscles indicating an attempt to maintain constant applied throwing force. A strong correlation is shown to exist between average score and decrease in mean integral ECG amplitude for the Flexor Pollicis Brevis.

Understanding teacher collaboration in disadvantaged urban primary schools: uncovering practices that foster professional learning communities

This study is set in the context of disadvantaged urban primary schools in Ireland. It inquires into the collaborative practices of primary teachers exploring how class teachers and support teachers develop ways of working together in an effort to improve the literacy and numeracy levels of their student. Traditionally teachers have worked in isolation and therefore ‘collaboration’ as a practice has been slow to permeate the historically embedded assumption of how a teacher should work. This study aims to answer the following questions. 1). What are the dynamics of teacher collaboration in disadvantaged urban primary schools? 2). In what ways are teacher collaboration and teacher learning related? 3). In what ways does teacher collaboration influence students’ opportunities for learning? In answering these research questions, this study aims to contribute to the body of knowledge pertaining to teacher learning through collaboration. Though current policy and literature advocate and make a case for the development of collaborative teaching practices, key studies have identified gaps in the research literature in relation to the impact of teacher collaboration in schools. This study seeks to address some of those gaps by establishing how schools develop a collaborative environment and how teaching practices are enacted in such a setting. It seeks to determine what skills, relationships, structures and conditions are most important in developing collaborative environments that foster the development of professional learning communities (PLCs). This study uses a mixed method research design involving a postal survey, four snap-shot case studies and one in depth case study in an effort to establish if collaborative practice is a feasible practice resulting in worthwhile benefits for both teachers and students.

The brand-orientated play-community: toxic play in the marketplace

This ethnographic study makes a number of original contributions to the consumer identity projects and the marketplace cultures dimensions of consumer culture theory research. This study introduces the notion of the brand-orientated play-community, a novel consumption community form, which displays, as locus, a desire to play. This contributes to our understanding of the fluid relationship between subcultures of consumption, consumer tribes, and brand community. It was found that the brand-orientated play-community’s prime celebration, conceptualised as the ‘branded carnival’, displays characteristics of the archetypal carnival. The community access carnivalistic life and a world-upside-down ethos via the use and misuse of marketplace resources. The branded carnival is further supported by the community’s enactment of ‘toxic play’, which entails abnormal alcohol consumption, black market illegal resources, edgework activities, hegemonic masculinity and upsetting the public. This play-community is discussed in terms of a hyper-masculine playpen, as the play enacted has a direct relationship with the enactment of strong masculine roles. It was found that male play-ground members enact the extremes of contrasting masculine roles as a means to subvert the calculated and sedate ‘man-of-action-hero’ synthesis. Carnivals are unisex, and hence, women have begun entering the play-ground. Female members have successfully renegotiated their role within the community, from playthings to players – they have achieved player equality, which within the liminoid zone is more powerful than gender equality. However, while toxic play is essential to the maintenance of collective identity within the culture so too is the more serious form of play: the toxic sport of professional beer pong. The author conceptualises beer pong as a ‘toxic sport’, as it displays the contradictory play foundations of agon and corrupt ilinx: this is understood as a milestone step in the emergence of the postmodern sport era, in which spontaneity and the carnivalesque will dominate.

Urbanisation and sport participation in townships in China

Urbanisation as a phenomenon is a complex social process which can be quite difficult to define and understand. In recent years, urbanisation in China has developed at an ever increasing rate. Urban population rates have now surpassed 50% (figure from 2011). Based on the growing importance placed on the increasing number of urbanised/urbanising townships, the issue of people’s lives within the townships has also become an important feature in regard to the impact that urbanisation is having upon China. Clearly this links China’s urban development to the transformation of sport participation in China. This research aims to examine what the reality of the sport participation on-the-ground is within six selective townships in China and examine the reasons for the reality through the lens of figurational theory. In order to do so, some features of Norbert Elias’s figurational theory (involvement and detachment, power) are employed as the theoretical framework. Two townships in Lüliang of Shanxi province, two townships in Jincheng of Shanxi Province and two townships in Huizhou of Guangdong province were selected in order to answer these key questions. The three cities which the townships are located are in different stages of urbanisation. Semi-structured interview were conducted. The current situation were described from the aspects of age, gender, occupation and income aspects and the transformation of sport participation. This research concludes that the current sport participation situation within these six townships is due to the influences stemming from several aspects: sport policy and sport organisation; economy condition, culture, urbanisation, and self-requirement and individual interest towards sport. This power forms a network of interdependency which also aids our understanding of the current sport participation within these six selected Chinese townships.

A social history of sport in Cork, Tipperary and Waterford, c. 1880-1930

This thesis seeks to explore the development of sport in Munster in the late nineteenth and early twentieth centuries by comparing developments in three counties: Cork, Tipperary and Waterford. In particular this thesis considers the development of rugby and soccer in comparative perspective across these three counties, asking what local factors impacted on their uneven development in the region and considering the extent to which the traditional model of diffusion applies to the reception of these sports in the three counties. By giving consideration to these two particular non-indigenous sports, the thesis will, through answering that question, explore ideas of cultural reception, national identity and class as expressed at local level. These themes will be explored by placing the comparative analysis of these two sports into a wider context of sporting development regionally and nationally in the period, in particular the emerging commercialisation of sport, and also the diverse sporting culture of which these two sports were a part. Utilising a wide range of archival sources from local, national and sporting newspapers, to club records, official publications and ephemera this thesis builds a picture of sport in Munster that is deeply rooted in the community, and that forms an important facet of the social world of Cork, Tipperary and Waterford from 1880-1930.

The development of a model of continuing professional development for teachers of primary science

A new science curriculum was introduced to primary schools in the Republic of Ireland in 2003. This curriculum, broader in scope than its 1971 predecessor (Curaclam na Bunscoile, 1971), requires teachers at all levels of primary school to teach science. A review carried out in 2008 of children’s experiences of this curriculum found that its implementation throughout the country was uneven. This finding, together with the increasing numbers of teachers who were requesting support to implement this curriculum, suggested the need for a review of Irish primary teachers’ needs in the area of science. The research study described in this thesis was undertaken to establish the extent of Irish primary teachers’ needs in the area of science by conducting a national survey. The data from this survey, together with data from international studies, were used to develop a theoretical framework for a model of Continuing Professional Development (CPD). This theoretical framework was used to design the Whole- School, In-School (WSIS) CPD model which was trialled in two case-study schools. The participants in these ‘action-research’ case-studies acted as co-researchers, who contributed to the development and evolution of the CPD model in each school. Analysis of the data gathered as part of the evaluation of the Whole-School, In- School (WSIS) model of CPD found an improved experience of science for children and improved confidence for teachers teaching at all levels of the primary school. In addition, a template for the establishment of a culture of collaborative CPD in schools has been developed from an analysis of the data

Achieving continuous professional development in higher education

Traditional higher education technology emphasizes knowledge transmission. In contrast, the Community platform presented in this paper follows a social approach that interleaves knowledge delivery with social and professional skills development, engaging with others, and personal growth. In this paper, we apply learning and complex adaptive systems theory to motivate and justify a continuous professional development model that improves higher education outcomes such as placement. The paper follows action design research (ADR) as the research method to propose and evaluate design principles.
