An energy efficient power controller switching methodology for an ambient healthcare network

A methodology for improved power controller switching in mobile Body Area Networks operating within the ambient healthcare environment is proposed. The work extends Anti-windup and Bumpless transfer results to provide a solution to the ambulatory networking problem that ensures sufficient biometric data can always be regenerated at the base station. The solution thereby guarantees satisfactory quality of service for healthcare providers. Compensation is provided for the nonlinear hardware constraints that are a typical feature of the type of network under consideration and graceful performance degradation in the face of hardware output power saturation is demonstrated, thus conserving network energy in an optimal fashion.

Managing diversity in practical ambient assisted living ecosystems

Though the motivation for developing Ambient Assisted Living (AAL) systems is incontestable, significant challenges exist in realizing the ambience that is essential to the success of such systems. By definition, an AAL system must be omnipresent, tracking occupant activities in the home and identifying those situations where assistance is needed or would be welcomed. Embedded sensors offer an attractive mechanism for realizing ambience as their form factor and harnessing of wireless technologies aid in their seamless integration into pre-existing environments. However, the heterogeneity of the end-user population, their disparate needs and the differing environments in which they inhabit, all pose particular problems regarding sensor integration and management

The CLARITY modular ambient health and wellness measurement platform

Emerging healthcare applications can benefit enormously from recent advances in pervasive technology and computing. This paper introduces the CLARITY Modular Ambient Health and Wellness Measurement Platform:, which is a heterogeneous and robust pervasive healthcare solution currently under development at the CLARITY Center for Sensor Web Technologies. This intelligent and context-aware platform comprises the Tyndall Wireless Sensor Network prototyping system, augmented with an agent-based middleware and frontend computing architecture. The key contribution of this work is to highlight how interoperability, expandability, reusability and robustness can be manifested in the modular design of the constituent nodes and the inherently distributed nature of the controlling software architecture.Emerging healthcare applications can benefit enormously from recent advances in pervasive technology and computing.

The intra-Traveller debate on ‘Traveller ethnicity’ in the Republic of Ireland. A critical discourse analysis

This dissertation assesses from an under-explored angle the enduring contention over Travellers’ ethnic recognition in the Republic of Ireland, particularly over the last decade. The novelty of this study concerns not only its specific focus on and engagement with the debate on ‘Traveller ethnicity’ among Traveller activists. It also pertains to the examination of Travellers’ arguments for and against ethnicity in light of critical theorisations as well as insights from identity politics. Furthermore, the adoption of a Critical Discourse Analytical framework offers new perspectives to this controversy and its potential implications. Finally, this thesis’ relevance extends beyond the contention on ‘Traveller ethnicity’ in itself. It also draws attention to the complex dynamics of colonisation and appropriation between the global and the local. Particularly, it points to the interplay between international human rights discourses and the local ones, formulated by NGOs struggling for equality. In this way it sheds light on more general issues such as the dialectical potential of human rights discourses: the benefits and pitfalls of framing recognition claims in the legalistic terms of human rights. In this study it is argued that the contention on ‘Traveller ethnicity’ defies a simplistic polarisation between Irish Travellers and the Irish State since it has been simultaneously played out within the Travelling community. Specifically, this study explores how ‘Traveller ethnicity’ has been introduced, embraced, promoted and contested within Traveller politics to the point of becoming a hotly debated and divisive issue among Traveller activists and at the heart of the community itself. Putting Traveller activists centre-stage, their discourses for and against ‘Traveller ethnicity’ are examined and assessed against one another and their potential implications for Traveller politics, policies and identities are pointed out. Contending discourses are historically contextualised as the product of specific structural, material and discursive configurations of power and socio-economic relations within Irish society. Discourses for and against ‘Traveller ethnicity’ are assessed as being significant beyond the representational level. They are regarded as contributing to dialectically constitute Travellers’ ways of being, representing and acting. Furthermore these discourses are considered as sites and means of power struggles, whose stakes are not only words, but relate to issues of power and leadership within the Travelling community; adjudications over material resources; the adoption of certain policy approaches over others; and, finally, the consolidation of certain subject positions over others for Travellers to draw upon and relate to mainstream society. This study highlights an ongoing ideological struggle for the naturalisation of ‘Traveller ethnicity’ as a self-evident ‘fact’, which involves no active choice by Travellers themselves. Overall, ‘Traveller ethnicity’ appears to constitute an enduring source of dilemmas for the Travelling community. These revolve around the contradictory potential of ethnicity claims-making —both its perils and advantages— and its status as a potent political strategic resource that can both challenge and reinforce existing power relations, policies and identities.

Caring for the Celtic cubs: Discursive constructions of mothers and mothering in the Irish childcare debate

Drawing on an understanding of the public sphere as a multiplicity of communicative and discursive spaces this paper examines the constructions of mothers, mothering and motherhood which emerged in recent debates about childcare in Ireland. Preliminary analysis of these discursive constructions suggest that they are often based on rhetoric, informed by stereotypical assumptions and rooted in frames of reference which mitigate against the emergence of alternative ways of understanding the issues of mothering and childcare. It will be argued that the reductionist and divisive nature of the childcare debate which ensued prior to the 2005 budget, stymied childcare policy development at a time when its unprecedented prominence on the political agenda and the strength of public finances could have underpinned a shift in policy approach. The paper concludes with an exploration of the ways in which feminist scholarship can challenge the Irish model of childcare policy, which continues to be premised on an understanding of childcare and the reconciliation of work and family life as the privatised responsibility of individual women.
