The purpose of this thesis is to explore the concept of resource scheduling and pricing and its relation to carrier aggregation. The first main topic is a modified Frank Kelly algorithm that allows for the use of utility functions that are piecewise concave, but not a member of a strictly \'diminishing return\' model. This adjustment to the Frank Kelly algorithm allows resource allocation to take into account devices with multiple applications. The second topic introduces the idea of scheduling resources in a carrier aggregation scenario assuming the carriers are scheduled sequentially. / Master of Science

Yes / The diversification of nursing and allied health profession (AHP) roles has seen unprecedented growth as organizations have sought to optimize limited health care resources. Within the UK health care system, the nonmedical consultant is viewed as the pinnacle of the clinical career ladder. Yet, nearly 15 years after their introduction, recruitment to these positions remains slow. Criticisms of nonmedical consultant practice include a lack of role clarity, a failure to work across the four domains of consultant practice, a lack of suitable applicants, and poor preparedness of new appointments. Although there is evidence exploring the nature and effectiveness of established consultant roles, little research addresses the development phase of aspiring consultants. Objectives To explore the transitional journey experienced by trainee consultant radiographers as they move from advanced to consultant practitioner within a locally devised consultant development programme. Design Longitudinal qualitative enquiry. Methods and Settings Five trainee consultant radiographers were recruited to a locally devised consultant practice development program within a single UK hospital trust. Semistructured interviews were undertaken at 1, 6, and 12 months with the trainees. Results A challenging journey was recounted involving five key emotional stages that occurred in a consistent and predictable order (ie, elation, denial, doubt, crisis, and recovery). The identified stages had close parallels with Hopson's Life Events model, suggesting that transition to consultant practice is a significant life event rather than a straightforward job promotion. Conclusions Current emphasis on the four domains of practice, although providing a clear framework for expected external role outcomes, overlooks the importance of the internal or subjective career development on the perceived success or failure of the role. Employers, educators, and professional bodies have a responsibility to facilitate aspirational consultants to explore and enhance their internal career development, offering more time to define themselves and their role with support to guide them through the transition journey.

Interest in the influence of emotions on behaviour, decision making, and leadership has accelerated over the last decade. Despite this, the influence of emotions on career advancement and behaviour within radiography and radiotherapy has largely been ignored. The ease of transition from one work role to another within an individual's career may be influenced by previous experience, personal characteristics, organizational environment, culture, and the nature of the role itself. Consequently, the transition from the often well-defined role of advanced or specialist practitioner to the more fluid role of consultant practitioner is associated with changing emotions as reported in the first part of this two-part series. What remains unexplored are the emotional triggers that pre-empt each stage in the transition cycle and how our understanding of these might support the successful implementation of consultant practitioner roles. To explore the emotional triggers that pre-empted each stage in the transitional journey of trainee consultant radiographers as they moved from advanced to consultant practitioner within a locally devised consultant development program. Five trainee consultant radiographers were recruited to a locally devised consultant practice development program within a single UK hospital trust. Semistructured interviews were undertaken at 1, 6, and 12 months with the trainees. Although all trainee consultant radiographers experienced the emotional events described in the first part of this two-part series in a predictable order (ie, elation, denial, doubt, crisis, and recovery), the timing of the events was not consistent. Importantly, four emotional triggers were identified, and the dominance of these and the reaction of individuals to them determined the emotional well-being of the individual over time. This study provides a unique and hitherto unexplored insight into the transition journey from advanced or specialist practitioner. Importantly, the findings suggest that commonly adopted supportive change interventions may, in fact, trigger the negative emotions they are intended to alleviate and disable rather than enable role transition.

No / Advanced practice roles are emerging in all disciplines at a rapid pace and reporting radiographers are ideally placed to work at such level. Advanced practitioners should demonstrate expert practice and show progression into three other areas of higher level practice. Most existing literature has focussed on the image interpretation aspect of the role, however there is little evidence that plain film reporting radiographers are undertaking activities beyond image interpretation and fulfilling the role of advanced practitioner. Letters were posted to every acute NHS trust in the UK, inviting reporting radiographers to complete an online survey. Both quantitative and qualitative information was sought regarding demographics and roles supplementary to reporting. A total of 205 responses were analysed; 83.3% of reporting radiographers describe themselves as advanced practitioner, however significantly less are showing progression into the four core functions of higher level practice. A total of 97.0% undertake expert practice, 54.7% have a leadership role, 19.8% provide expert lectures and 71.1% have roles encompassing service development or research, though most of these fall into the service development category. 34.5% felt that they were aware of the differences between extended and advanced practice though much less (9.3%) could correctly articulate the difference. Few individuals are aware of the difference between extended and advanced practice. Though the majority of plain film reporting radiographers identify themselves as advanced practitioners, significantly less evidence all four core functions of higher level practice. The number of individuals undertaking research and providing expert-level education is low.

Yes / Measuring the spatial extent of defects may be advantageous in advanced glaucoma where conventional perimetric sensitivity measurements are unreliable. We test whether suprathreshold tests on a higher density grid can more efficiently map advanced visual field loss. Data from 97 patients with mean deviation / Supported by a College of Optometrists Research Fellowship (to JD).

No / Advanced Dental Biomaterials is an invaluable reference for researchers and clinicians within the biomedical industry and academia. The book can be used by both an experienced researcher/clinician learning about other biomaterials or applications that may be applicable to their current research or as a guide for a new entrant into the field who needs to gain an understanding of the primary challenges, opportunities, most relevant biomaterials, and key applications in dentistry.

Nanocomposite thin films with gold nanoparticles embedded in a host metal oxide prepared by spray pyrolysis deposition have been investigated. A single-step process has been developed using a one-pot solution containing precursors for both gold nanoparticles and host metal oxides. The films obtained display combined features of colouration, electrical conductivity and solar control. In this study two precursors for gold nanoparticles were used: preformed gold colloids and HAuCl₄. Three metal oxide host materials, TiO₂, SnO₂ and ZnO, were investigated. These films were deposited at a substrate temperature of 200-600 °C. Powder X-ray diffraction analysis reveals the presence of metallic gold. SEM inspection typically showed particulate gold of 5-20 nm in diameter, distributed at the surface or within the host matrix. Optical spectroscopy showed an intense absorption in the visible region due to the characteristic surface plasmon resonance (SPR) effects of gold nanoparticles. The wavelength of the SPR peaks varies depending on the refractive index of surrounding host material which is significantly influenced by the substrate deposition temperature. On the other hand, SnO₂ and ZnO, together with the introduction of dopants, were further investigated as suitable materials for transparent conducting oxides (TCO). SnO₂:F films were found to attain very low electrical resistivity, while ZnO films exhibit higher transparency in the visible. A double layered structure with a TCO layer of SnO₂:F on top of a layer embedded with gold nanoparticles has been employed to achieve the combined functionalities of conductivity and colouration. The electrical conductivity is significantly enhanced compared to a nanocomposite single layer film due to the introduction of the TCO top layer. In this thesis, spray pyrolysis deposition has demonstrated a simple and rapid approach to the production of a variety of thin films. It can be immediately integrated with current industrial coating equipment and scaled up for large-scale production process.

In 2006 the College Board celebrated the 50th anniversary of the Advanced Placement (AP) program. The AP program, which began as a means of transitioning selected high school students to colleges, had expanded to include thousands of students sitting for thousands of exams. During the first fifty years as the program expanded, the College Board expanded the number of course offerings. With this expansion came the question as to the effectiveness of AP. As criticism of the College Board continued to grow, by 2006 the College Board began reform by auditing its own courses, seeking funding for states to expand experimental programs, and encouraging universities to no longer accept a score of 3 on an exam. The College Board sought overall clarity regarding the focus of the AP program once considered an elite standard in America high schools. While there is cause to wonder, there is also encouragement. / Department of Educational Leadership

The presented diploma thesis deals with the issue of wire electrical discharge machining of SiSiC ceramics. The first part explains the principles of electrical discharge machining, describes the WEDM technology and presents the properties of the advanced ceramics. The second part consists of a detailed analysis of the cutting process of eighteen samples obtained with systematically changing process parameters. Based on the obtained results from EDX analysis, SEM electron microscopy and topography there was performed an analysis of the influence of process parameters on the cutting speed, surface roughness, kerf width and number of wire breaks with usage of the selected brass cutting wire. From the evaluated results it was possible to select a combination of parameters that ensured a stable machining process.
