Original compositions using contemporary classical and jazz techniques accompanied by technical analysis Vol. I
Get PDFThis portfolio of compositions consists of six major works and is accompanied by a technical analysis of each. Nature, the sky, astronomy, clouds and many fields of science have always fascinated me and four of the works presented here are heavily influenced by this fascination. The two remaining works are inspired by my interest in computing, computer programming and the possibilities opened up by the use of computers in composition.
The first work, title Jupiter Moons Suite is a five-movement work for solo piano that is composed using the four permutations of a twelve-tone row. The first four movements each describe one of the four Galilean moons of Jupiter, while the final movement describes the surface of Jupiter itself.
Aurora Borealis, the second work submitted, is for an eight-voice female choir. It is a setting of a passage of prose about the northern lights that uses synthsesia to relate sounds to colours.
If-Then is a work for improvising ensemble that looks at the possibility of allowing the performers to determine large-scale compositional elements based on chance events that happen during the performance. It is a jazz-inspired suite that has many improvised passages.
Cumulus is a string quartet in one movement. It is influenced by my interest in the clouds. It uses melodic movement along a symmetrical axis and has asymmetric rhythmic ostinatos.
The fifth work is Elements, a piece for chamber ensemble and triggered sounds. It uses spectral analysis to blend live and pre-recorded sounds.
The final work Zenith is for 16 voices and orchestra. Like Cumulus, it is strongly influenced by the changing of clouds in the sky
Riordan arrays, orthogonal polynomials as moments, and Hankel transforms
Get PDFTaking the examples of Legendre and Hermite orthogonal polynomials, we show
how to interpret the fact that these orthogonal polynomials are moments of other
orthogonal polynomials in terms of their associated Riordan arrays. We use these
means to calculate the Hankel transforms of the associated polynomial sequences
Spirituality and the Celtic Tiger period: changes experienced by senior business leaders in the South East of Ireland
Get PDFThis study explores changes experienced in the level and quality of spirituality among a representative group of business leaders from the South East region of Ireland, during the period of the ‘Celtic Tiger’, and the period since, a time of significant economic and cultural
change.
A phenomenological approach was adopted for the research, using a qualitative method of data collection and analysis. Eighteen semi structured in-depth interviews were conducted with business leaders,with diversity in background, business involvement, age and gender. The research found that Spirituality does have a role in work, and
people cannot leave their Spirituality at home. Spirituality in work is mainly to do with values, and expressed most frequently in dealings with people. There was a change in the experience of spirituality during the Celtic Tiger period, manifested by a dilution in personal
values, with an increased concentration on personal material gain
Performance management of acute-care hospitals in HSE South
No full textThe experience of poor macroeconomic performance in the past has directed the Irish government towards new public management (NPM) in an attempt to reform public sector organisations and drive efficiency. More recently an economic boom has contributed to a changing population structure and facilitated greater funding of public sector organisations, particularly the health service. The literature shows that acute-care hospitals receive a substantial portion (38%) of the health service budget yet there are few studies involving performance management in this setting. This study explores the effect of NPM and the institutional environment on the development of performance management in an acute-care hospital setting. The study was based on three hospitals located in the Health Service Executive (HSE) South region. The primary research data was obtained from initial questionnaires and in-depth interviews with senior hospital management. Additional primary data was collected from in-depth interviews conducted with two senior HSE managers. Secondary data was gleaned from a range of documentary and other sources. The findings indicate that many of the aspects of NPM suggested in the literature were present and influential in directing health service reform. One of the most significant reform initiatives, the establishment of the HSE, has brought greater accountability and by improving information reporting, greater transparency and focus on hospital performance. A number of obstacles that may impinge on future reform were identified and in addition, research evidence suggests that change initiatives have produced some unexpected results. In relation to the institutional environment the findings suggest that this has also influenced the development of hospital performance management. There is evidence of legitimacy, the existence of rationalised myths and decoupling in the health service. The findings provide evidence of coercive, mimetic and normative isomorphism as hospitals comply with institutional pressures. The research indicates that there has been a shift in institutional logics whereby medical consultants are demonstrating greater interest in and engagement with hospital management and are facilitating a multi-disciplinary team approach to performance management. The study has added to the existing literature by demonstrating that NPM reform has influenced the Irish health service in both expected and unexpected ways. It also suggests that institutional theory provides a plausible explanation for the adoption of particular performance management practices. By eliciting the views and opinions of senior management members of an acute-care hospital the study has provided a unique insight into the issues and difficulties involved in monitoring performance on an ongoing basis
Finding the Red Thread: The Role of the Learning Space in Transformative Learning in Executive Education
Get PDFThe adult education and critical reflection fields have developed new perspectives in recent years. Studies show that achieving congruence in teaching-learning environments is essential to enhancing the experience and quality of learning. Students’ evolving ways of thinking and practising in a subject area underpin their mastery of the subject. By concentrating course design on specific module outcomes rather than the fundamental goals of the subject or discipline area, students fail to make connections between topics and do not come to see the subject as an integrated whole.
This action research study was conducted over a four-year period focusing on the development of teaching-learning environments in executive education in a Scandinavian context. It investigates the nature of transformative learning in executive education and its relation to the identification of a distinctive learning space. Therefore, in the light of the organisation project, particular contributions to knowledge from this research study apply to the tradition of critical reflection. They apply particularly in the area of transformative learning through the development of a framework for creating a distinctive learning space in executive education.
The research has identified the key role of the learning team, coupled with a range of components that must be employed within the learning space, that emerged as a distinct contribution to the area of transformative learning. The learning team must understand that its role is to enhance personal leader development and, then, to work with support systems, including mentors, in a collaborative effort to enhance the learning experience of everyone in the team. Trusted relationships between members of the learning team are essential to the development of dialogue, critical reflection and profound discourse

On a generalization of the Narayana triangle
Get PDFBy studying various ways of describing the Narayana triangle, we provide a number
of generalizations of this triangle and study some of their properties. In some cases,
the diagonal sums of these triangles provide examples of Somos-4 sequences via their
Hankel transforms
Older Men's Lives - A Qualitative Study
Get PDFThis study explores the experiences of older single men living alone and in poverty in a post-Celtic Tiger society. It traces the lives and living environment of twelve older men many of whom were born around the foundation of the State. It examines the life course events which influenced these older men’s present living circumstances in an attempt to answer the question did these older men benefit from a good quality of life as envisaged by the founders of The Republic of Ireland, and if not why not. Through semi-structured qualitative ‘conversational’ style interviews (Rubin and Rubin, 1995), the older men recall aspects of their lives and events which they found to be important.
The study illustrates the difficult and harsh times these men, their exiled siblings and parents lived through. It is perhaps timely to have the benefit of the insights of these older men who lived through some of the world’s harshest economic periods, just as we face into a decade of enormous fiscal and social challenges due to the current domestic financial crisis and global recession. This generation however has the advantages of modern technology to support them in their quest for self-fulfilment and the benefit of a sound education to assist them in furthering their life goals. The modern world is globalised and multi-cultural unlike the world that the older men of this study were reared in
Implementation and evaluation of the Shim6 protocol in the Linux kernel
Get PDFIn the changing landscape of the todays Internet, several solutions are under investigation to allow efficient, flexible and scalable multihoming. One of the proposals is shim6, a host-based multihoming solution based on the use of multiple IPv6 addresses on each host. In this work, we first describe the main features of this protocol, then we explain our implementation of shim6, along with the associated security mechanisms in the Linux kernel and, finally, we evaluate its performance. In particular, we analyse the performance impact of the security mechanisms used by shim6 and the impact of shim6 on the performance of end-host systems, especially heavily loaded servers. We conclude by discussing the remaining open issues for a widespread deployment of host-based multihoming techniques such as shim6
