The central research question of this thesis asks the extent to which Irish law, policy and practice allow for the application of the United Nations Convention on the Rights of the Child (CRC) to pre-natal children. First, it is demonstrated that pre-natal children can fall within the definition of ‘child’ under the Convention and so the possibility of applying the Convention to children before birth is opened. Many State Parties to the CRC have interpreted it as applicable to pre-natal children, while others have expressed that it only applies from birth. Ireland has not clarified whether or not it interprets it as being applicable from conception, birth, or some other point. The remainder of the thesis examines the extent to which Ireland interprets the CRC as applicable to the pre-natal child. First, the question of whether Ireland affords to the pre-natal child the right to life under Article 6(1) of the Convention is analysed. Given the importance of the indivisibility of rights under the Convention, the extent to which Ireland applies other CRC rights to pre-natal children is examined. The rights analysed are the right to protection from harm, the right to the provision of health care and the procedural right to representation. It is concluded that Ireland’s laws, policies and practices require urgent clarification on the issue of the extent to which rights such as protection, health care and representation apply to children before birth. In general, there are mixed and ad hoc approaches to these issues in Ireland and there exists a great deal of confusion amongst those working on the frontline with such children, such as health care professionals and social workers. The thesis calls for significant reform in this area in terms of law and policy, which will inform practice.

The aim of this study is to garner comparative insights so as to aid the development of the discourse on further education (FE) conceptualisation and the relationship of FE with educational disadvantage and employability. This aim is particularly relevant in Irish education parlance amidst the historical ambiguity surrounding the functioning of FE. The study sets out to critically engage with the education/employability/economy link (eee link). This involves a critique of issues relevant to participation (which extends beyond student activity alone to social relations generally and the dialogic participation of the disadvantaged), accountability (which extends beyond performance measures alone to encompass equality of condition towards a socially just end) and human capital (which extends to both collective and individual aspects within an educational culture). As a comparative study, there is a strong focus on providing a way of conceptualising and comparatively analysing FE policy internationally. The study strikes a balance between conceptual and practical concerns. A critical comparative policy analysis is the methodology that structures the study which is informed and progressed by a genealogical method to establish the context of each of the jurisdictions of England, the United States and the European Union. Genealogy allows the use of history to diagnose the present rather than explaining how the past has caused the present. The discussion accentuates the power struggles within education policy practice using what Fairclough calls a strategic critique as well as an ideological critique. The comparative nature of the study means that there is a need to be cognizant of the diverse cultural influences on policy deliberation. The study uses the theoretical concept of paradigmatic change to critically analyse the jurisdictions. To aid with the critical analysis, a conceptual framework for legislative functions is developed so as to provide a metalanguage for educational legislation. The specific contribution of the study, while providing a manner for understanding and progressing FE policy development in a globalized Ireland, is to clear the ground for a more well-defined and critically reflexive FE sector to operate and suggests a number of issues for further deliberation.

Recent years have witnessed a rapid growth in the demand for streaming video over the Internet, exposing challenges in coping with heterogeneous device capabilities and varying network throughput. When we couple this rise in streaming with the growing number of portable devices (smart phones, tablets, laptops) we see an ever-increasing demand for high-definition videos online while on the move. Wireless networks are inherently characterised by restricted shared bandwidth and relatively high error loss rates, thus presenting a challenge for the efficient delivery of high quality video. Additionally, mobile devices can support/demand a range of video resolutions and qualities. This demand for mobile streaming highlights the need for adaptive video streaming schemes that can adjust to available bandwidth and heterogeneity, and can provide us with graceful changes in video quality, all while respecting our viewing satisfaction. In this context the use of well-known scalable media streaming techniques, commonly known as scalable coding, is an attractive solution and the focus of this thesis. In this thesis we investigate the transmission of existing scalable video models over a lossy network and determine how the variation in viewable quality is affected by packet loss. This work focuses on leveraging the benefits of scalable media, while reducing the effects of data loss on achievable video quality. The overall approach is focused on the strategic packetisation of the underlying scalable video and how to best utilise error resiliency to maximise viewable quality. In particular, we examine the manner in which scalable video is packetised for transmission over lossy networks and propose new techniques that reduce the impact of packet loss on scalable video by selectively choosing how to packetise the data and which data to transmit. We also exploit redundancy techniques, such as error resiliency, to enhance the stream quality by ensuring a smooth play-out with fewer changes in achievable video quality. The contributions of this thesis are in the creation of new segmentation and encapsulation techniques which increase the viewable quality of existing scalable models by fragmenting and re-allocating the video sub-streams based on user requirements, available bandwidth and variations in loss rates. We offer new packetisation techniques which reduce the effects of packet loss on viewable quality by leveraging the increase in the number of frames per group of pictures (GOP) and by providing equality of data in every packet transmitted per GOP. These provide novel mechanisms for packetizing and error resiliency, as well as providing new applications for existing techniques such as Interleaving and Priority Encoded Transmission. We also introduce three new scalable coding models, which offer a balance between transmission cost and the consistency of viewable quality.
