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.

Genteel revolutionaries: the lives of Anna and Thomas Haslam

The lives of Thomas and Anna Haslam were dedicated to the attainment of women's equality. They were feminists before the word was coined. In an era when respectable women were not supposed to know of the existence of prostitutes, Anna became empowered to do the unthinkable, not only to speak in public but to discuss openly matters sexual and to attack the double standard of sexuality which was enshrined in the official treatment of prostitutes. Their life-long commitment to the cause of women's suffrage never faltered, despite the repeated discouragement of the fate of bills defeated in the House of Commons. The Haslams represented an Ireland which did not survive them. While they were dedicated to the union with Westminster, they worked happily with those who applied themselves to its destruction. Although in many ways they exemplified the virtues of their Quaker backgrounds, they did not subscribe to any organised religion. Despite living in straitened circumstances, they were part of an urban intellectual elite and participated in the social and cultural life of Dublin for over fifty years. It is tempting to speculate how the Haslams would have fared in post independence Ireland. Hanna Sheehy Skeffington who had impeccable nationalist credentials, was effectively marginalised. It is likely that they would have protested against discriminatory legislation in their usual law abiding manner but, in a country which quickly developed an overwhelmingly Roman Catholic ethos, would they have had a voice or a constituency? Ironically, Thomas's teaching on chastity would have found favour with the hierarchy; his message was disseminated in a simple and more pious manner in numerous Catholic Truth Society pamphlets. The Protestant minority never sought to subvert the institutions of the state, was careful not to criticise and kept its collective head down. Dáil Éireann was not bombarded with petitions for the restoration of divorce facilities or the unbanning of birth control. Those who sought such amenities obtained them quietly 'in another jurisdiction.' Fifty years were to pass before the condom wielding 'comely maidens' erupted on to the front pages of the Sunday papers. They were, one imagines, the spiritual descendants of the militant rather than the constitutional suffrage movement. "Once and for all we need to commit ourselves to the concept that women's rights are not factional or sectional privileges, bestowed on the few at the whim of the many. They are human rights. In a society in which the rights and potential of women are constrained no man can be truly free." These words spoken by Mary Robinson as President of Ireland are an echo of the principles to which the Haslams dedicated their lives and are, perhaps, a tribute to their efforts.

The political and economic context of Keynes’s 1933 Finlay lecture: transforming a business practitioner’s ways of knowing

This thesis is structured in the format of a three part Portfolio of Exploration to facilitate transformation in my ways of knowing to enhance an experienced business practitioner’s capabilities and effectiveness. A key factor in my ways of knowing, as opposed to what I know, is my exploration of context and assumptions. By interacting with my cultural, intellectual, economic, and social history, I seek to become critically aware of the biographical, historical, and cultural context of my beliefs and feelings about myself. This Portfolio is not exclusively for historians of economics or historians of ideas but also for those interested in becoming more aware of how these culturally assimilated frames of reference and bundles of assumptions that influence the way they perceive, think, decide, feel and interpret their experiences in order to operate more effectively in their professional and organisational lives. In the first part of my Portfolio, I outline and reflect upon my Portfolio’s overarching theory of adult development; the writings of Harvard’s Robert Kegan and Columbia University’s Jack Mezirow. The second part delves further into how meaning-making, the activity of how one organises and makes sense of the world and how meaning-making evolves to different levels of complexity. I explore how past experience and our interpretations of history influences our understandings since all perception is inevitably tinged with bias and entrenched ‘theory-laden’ assumptions. In my third part, I explore the 1933 inaugural University College Dublin Finlay Lecture delivered by economist John Maynard Keynes. My findings provide a new perspective and understanding of Keynes’s 1933 lecture by not solely reading or relying upon the text of the three contextualised essay versions of his lecture. The purpose and context of Keynes’s original longer lecture version was quite different to the three shorter essay versions published for the American, British and German audiences.

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

The examination of the traditional femininity and women’s lives in ancient China

This thesis explores the evolution of the concept of traditional Chinese femininity in relation to women’s lives in ancient China (221 BCE – A.D.1840). It proposes that the traditional Chinese femininity had been trying to seek a balance between the permanent principles and contingency plans for the stability and development of the society, which caused women’s humiliation and freedom. In reality, politicians and thinkers in ancient China had been transforming the concept of femininity itself to make it more adaptable to the social conditions of that time. This may be discussed in terms of three aspects. Firstly, the traditional concept of Chinese human relationships, including the ethical order, always emphasised the influence of individual behaviour on others and the overall stability and linked development of family, society and nation. Thus, both men and women, must be placed within this interrelated, interacting and cooperating relationship. Secondly, the association of family and country created an overlap of family and public affairs, which, objectively, facilitated the movement of women from the inner to the public arena. Thirdly, the notions of political and ethical morality and of men’s virtues and women’s virtues were integrated because of the union of family and nation. Therefore, typically virtuous women could be a source of encouragement for men and, furthermore, men formulated their virtues in the public space by formulating women’s virtues in the private space. The shaping of the gender image and concept of women in ancient China reflected the country’s changing cultural and gender norms. Chinese femininity and lifestyles, like Chinese history, were a continuous presence in the society but were also constantly changing. Through this study, it could be noted that Chinese women were not hidden and that their subjectivity and the concepts motivating them were not merely devised by a male-dominated society and culture.

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.
