The role of choice in the development of an M-government strategy in Turkey

Enhanced data services through mobile phones are expected to be soon fully transactional, interactive and embedded with other mobile consumption practices. While private services will continue to take the lead in the mobile data revolution, others such as government and NGOs are becoming more prominent m-players. This paper adopts a qualitative case study approach interpreting micro-level municipality officers’ mobility concept, ICT histories and choice practices for m-government services in Turkey. The findings highlight that in-situs ICT choice strategies are non-homogenous, sometimes conflicting with each other, and that current strategies have not yet justified the necessity for municipality officers to engage and fully commit to m-government efforts. Furthermore, beyond m-government initiatives’ success or failure, the mechanisms related to public administration mobile technical capacity building and knowledge transfer are identified to be directly related to m-government engagement likelihood.

Detection of signals corrupted by the combination of Gaussian and Non-Gaussian noise

The detection of signals in the presence of noise is one of the most basic and important problems encountered by communication engineers. Although the literature abounds with analyses of communications in Gaussian noise, relatively little work has appeared dealing with communications in non-Gaussian noise. In this thesis several digital communication systems disturbed by non-Gaussian noise are analysed. The thesis is divided into two main parts. In the first part, a filtered-Poisson impulse noise model is utilized to calulate error probability characteristics of a linear receiver operating in additive impulsive noise. Firstly the effect that non-Gaussian interference has on the performance of a receiver that has been optimized for Gaussian noise is determined. The factors affecting the choice of modulation scheme so as to minimize the deterimental effects of non-Gaussian noise are then discussed. In the second part, a new theoretical model of impulsive noise that fits well with the observed statistics of noise in radio channels below 100 MHz has been developed. This empirical noise model is applied to the detection of known signals in the presence of noise to determine the optimal receiver structure. The performance of such a detector has been assessed and is found to depend on the signal shape, the time-bandwidth product, as well as the signal-to-noise ratio. The optimal signal to minimize the probability of error of; the detector is determined. Attention is then turned to the problem of threshold detection. Detector structure, large sample performance and robustness against errors in the detector parameters are examined. Finally, estimators of such parameters as. the occurrence of an impulse and the parameters in an empirical noise model are developed for the case of an adaptive system with slowly varying conditions.

Logics of marginalisation in health and social care reform:integration, choice, and provider-blind provision

The period 2010–2013 was a time of far-reaching structural reforms of the National Health Service in England. Of particular interest in this paper is the way in which radical critiques of the reform process were marginalised by pragmatic concerns about how to maintain the market-competition thrust of the reforms while avoiding potential fragmentation. We draw on the Essex school of political discourse theory and develop a ‘nodal’ analytical framework to argue that widespread and repeated appeals to a narrative of choice-based integrated care served to take the fragmentation ‘sting’ out of radical critiques of the pro-competition reform process. This served to marginalise alternative visions of health and social care, and to pre-empt the contestation of a key norm in the provision of health care that is closely associated with the notions of ‘any willing provider’ and ‘any qualified provider’: provider-blind provision.

Exploring care relations in later life: disentangling notions of care and choice

The experience of later life varies widely and is often framed in terms of the active lifestyles of the Third Age and the frailty and abjection of the Fourth Age. This thesis sought to understand how the concepts of care and choice are enacted, experienced and interrelated in the context of both informal and formal care in later life and how older people themselves, their families and significant others understand and experience these concepts. The discourse of personalisation that dominates care services has led to an emphasis on individual choice, control and independence so that those in need of care are faced with what has been described as the ‘logic of choice’, a focus on individual responsibility rather than care. Adopting a Feminist Foucauldian theoretical approach and drawing on Tronto’s (1993) ethic of care, this thesis explores the experiences of older people and their informal carers through dialogical narrative analysis. The stories begin with the recognition by individuals that there is a need for care and how this need is met through negotiations with families and significant others. As needs increase the physical and logistical limits of informal care by individuals are reached, often leading to a need to ‘choose’ formal care. Rather than impacting solely on the care recipient, formal care is shown as being an experience that is shared with informal carers. Indeed, the participants depict how informal care continues alongside formal care and how the boundaries between them become blurred. I argue that a binary division between actively making choices and being a passive recipient are not appropriate to understandings of care. By disentangling the notions of care and choice this thesis explores the extent to which these concepts are relevant to the experience of older people in specific care situations.
