Yes / To survey the diagnostic radiography workforce in the United Kingdom (UK) at an organisational level to ascertain the scope of advanced practice and compliance with Health Education England standards for multiprofessional advanced clinical practice (ACP). 174 diagnostic imaging departments were invited to participate in a cross-sectional electronic survey focused upon advanced level practice and their educational and accreditation expectations (October-December 2019). Breast imaging, computed tomography, fluoroscopy, interventional radiology, lithotripsy, magnetic resonance imaging and projectional radiography were included. A total of 97 responses were received, of which 79 were eligible for inclusion (45%). Respondents reported advanced-level practice roles across all imaging modalities, which included clinical reporting, procedural-based and combined roles. Radiograph and mammogram reporting were most prevalent (95 and 67% of Trusts), with fluoroscopy the most frequent procedure-only role (25%). Only 39% of trusts required adherence to the four pillars of ACP within job descriptions, and only 12% requiring a full Masters qualification. Diagnostic radiographer reporting and procedure-based roles in the NHS are varied and widespread. However, inconsistencies in fulfilment against the expected standards for advanced practice exist. Realignment of advanced-level roles to delineate enhanced and advanced clinical practice may ensure consistency between roles and professions. A requirement for accreditation as an advanced (clinical) practitioner with adherence to advanced practice requirements could therefore provide value to accreditation for both individual practitioners and Trusts. Within the UK, diagnostic radiographer roles previously self-identified as advanced-level practice may be termed enhanced practice when not adhering to expected ACP standards.

Yes / There has been an increase in development of technologies that can deliver personalised dietary advice. Devising healthy, sustainable dietary plans will mean taking consideration of extrinsic factors such as individual social circumstances. The aim of this study was to identify societal groups more or less receptive to and likely to engage with digitally delivered personalised nutrition initiatives. Sample and Methods: Volunteers were recruited via a social research agency from within the UK. The resultant sample (N=1061) was 49% female, aged 18-65 years. Results: MANOVA (Tukey HSD applied) indicated that females and younger people (aged 18-29 years) had more favourable attitudes and were more likely to intend to adopt personalised nutrition. There were no differences in attitude toward or intention to adopt personalised nutrition between different education levels, income brackets or occupational groups. Conclusion: These results imply that females and younger people may be most likely to adopt personalised nutrition in the future. Initiatives to promote personalised nutrition should target males and older people.

Yes / Ramadan is a month-long religious festival observed by Muslims worldwide, characterised by intermittent fasting. This qualitative study addressed the need to understand how fasting is experienced by Muslims residing in Western cultures, aiming to inform policies that create a more supportive environment. Practicing Muslims, both men and women, were recruited in the North of England in the United Kingdom (UK). Data were collected by individual interviews (N=7) and focus group discussion and then analysed using Social Ecological Theory as a framework. Fasting was managed at the individual level through instrumental food choice and eating practices, and by adapting sleep routines. Disrupted sleep routines posed a challenge for those who had to adhere to Western working schedules, leading to perceived detriments to cognitive function and mood. The sense of belonging associated with Ramadan was seen as a motivating factor for fasting. Breaking the fast (Iftar) was marked by social activity and the availability of traditional fried foods. Participants identified the wider Western culture and environment as challenging for those who are fasting. These findings imply a need for policies that enable flexible working practices for Muslims during Ramadan.

L’objectif de ma thèse est de mieux comprendre le fonctionnement de deux proxies de température de surface de l’océan (SST), les indices Uk’37 et TEX86, notamment en terme de saison et de profondeur de production des alcènones et des tétraéthers sur lesquels ils reposent, au cours des 160 000 dernières années au niveau de la marge ibérique. L’originalité de ce projet de thèse réside dans sa double approche, avec d’une part l’acquisition des enregistrements sédimentaires, et d’autre part l’utilisation d’un outil de modélisation régionale couplée physique-biogéochimie pour simuler ces proxies sous 3 modes climatiques : au présent, lors du dernier maximum glaciaire, et lors d’événements de Heinrich. La confrontation des résultats des biomarqueurs avec ceux de tests de scénarios de production par la modélisation ont conduit aux conclusions suivantes. L’Uk’37 enregistre bien des SSTs moyennes annuelles, alors que le TEX86 présente a priori des températures beaucoup trop élevées pour cette zone. La formulation d’une calibration régionale pour le TEX86 permet d’obtenir des SSTs moyennes annuelles cohérentes. Le meilleur endroit de la marge ibérique pour appliquer ces deux paléothermomètres est le site de Shackleton. Après analyse fine des timings des signaux multiproxies, le TEX86 semble être produit à des profondeurs intermédiaires, potentiellement par des communautés d’Archées d’origine méditerranéenne. Les variations de gradients thermiques latitudinaux ont été quantifiées, et des réorganisations de masses d’eaux de surface et intermédiaire au niveau de la marge ibérique ont été envisagées selon le climat glaciaire/interglaciaire lors des évènements de type Heinrich. / My PhD project aims at better understanding the functioning of both organic proxies of sea surface temperature (SST), Uk’37 and TEX86, especially in terms of season and depth of alkenone and tetraether production, over the last 160 000 years on the Iberian Margin. The originality of this project lies in its double approach: on the one hand, with the acquisition of Uk’37 and TEX86 sedimentary records from the Iberian Margin, and on the other hand with the use of a coupled physics-biogeochemistry regional model to simulate these temperature proxies for 3 climate modes: at present, during the last glacial maximum, and during Heinrich Stadials. The comparison of biomarker results with those from modeling tests of production scenarios provided the following conclusions. Uk’37 does record annual mean SSTs, whereas TEX86 shows a priori too high temperature for this area. The formulation of a regional calibration for TEX86 index enables to obtain coherent past annual mean SSTs. The best location to apply both paleothermometers on the Iberian Margin is the Shackleton site. After refined analysis of multiproxy signal timings, TEX86 production seems to take place at intermediate depth, potentially by archaean communities coming from the Mediterranean Sea. Latitudinal thermal gradient variations are quantified, and glacial/interglacial surface and intermediate water masses reorganizations during 'Heinrich like' events are considered.

This is a study of approaches to fisheries management in the United Kingdom (UK) between 1945 and 1996. It examines the choices and incentives faced by UK Governments when designing policy instruments to deliver international commitments to sustainable fishing. The failure of international agreements to sustainably manage fisheries resources is often attributed to international institutions, the politicization of negotiations and their distributive outcomes. This thesis makes an original contribution by arguing that the success of international agreements was also dependent upon local negotiations that shaped the design of national delivery mechanisms. The central research question concerns the role and influence of local interests in delivering global economic and environmental agendas and how national governments accommodate local tensions within this process. A sustained content analysis of UK Government archives is used to argue that local political and sectional industry interests had a significant bearing on the development of UK fisheries policy and the design of domestic delivery mechanisms. The exception was UK policy on the international distribution of fisheries resources at the United Nations Law of the Sea Conferences (1958, 1960 and 1973-82). Economic considerations drove early environmental policy with sectional fishing industry interests of secondary importance to the potential economic benefits associated with the more valuable energy resources. In then seeking to implement controls on fishing activity, this thesis argues that UK fisheries management mechanisms were designed to compensate for tension between global commitments mandating a reduction in fishing effort and the local fleets and communities that had to bear the costs of industry contraction. This created a policy-making environment in which social and political motivations continually trumped the application of economic and scientific advice. This advice advocated a contraction in the size of the fleet which had become necessary as technical change and falling stocks resulted in overcapacity. The use of fisheries policy as a political tool to ease local tensions incentivised policy choices that directly contributed to the UK's failure to reduce fishing pressure and deliver international commitments. This thesis demonstrates the importance of local negotiations and interests in the construction of national and international approaches to environmental and natural resources problems.

This thesis is a history of American and British efforts to halt or retard the Pakistani nuclear weapons programme. It assesses US and UK non-proliferation policy towards Pakistan from the Indian nuclear test of May 1974 to the decline of anti-proliferation activity in 1979 and 1980. A broadly chronological analysis of key government and media sources from American and British archives highlights the development of non-proliferation policy and the factors that influenced anti-proliferation activity. Scrutiny of British-and not just American-involvement in Pakistan's nuclear programme permits an assessment of the existence of a 'non-proliferation special relationship' between Washington and London. This study demonstrates that successive British governments played a significant role in creating, shaping, and at times adversely affecting, non-proliferation activity on the sub-continent. Additionally, this thesis demonstrates that the UK frequently deprioritised non-proliferation concerns in favour of economic considerations, creating tension between London and Washington. Thus, it is shown that there was a close working relationship between the US and UK governments, but the relationship was riven with fissures. Alongside this examination of British policy, this study also examines American policy and attitudes, demonstrating that infighting and conflicts between strategic priorities impaired the effectiveness of American non-proliferation policy. Furthermore, this study offers a detailed examination of the cultural underpinnings of UK-US non-proliferation policy directed against Pakistan. It demonstrates that-contrary to popular and long-lasting media representations-the paradigm of an 'Islamic bomb' played no part in the creation and application of non-proliferation policy. This thesis makes it clear that in UK-US efforts to halt or retard Pakistani nuclear attainment, issues of credibility and global standing were far more significant than religious factors. Overall, this study examines a key moment in non-proliferation history and offers new findings on the Anglo-American relationship and the role of cultural factors in shaping foreign policy.

Les alcénones sont largement utilisées comme proxys pour estimer des températures d’eaux de surface océanique ou des pressions partielles de CO2 (pCO2) dans des périodes anciennes. Dans les océans actuels, ces cétones à longues chaînes carbonées sont essentiellement produites par les coccolithophoridés Emiliania huxleyi et Gephyrocapsa oceanica. Il existe toutefois un écart temporel important entre le premier enregistrement sédimentaire des alcénones au Crétacé (~120 Ma) et la première apparition des producteurs actuels (< 2 Ma). Il apparaît donc essentiel d’identifier les producteurs anciens d’alcénones afin d’assurer la fiabilité des proxys environnementaux basés sur ces biomarqueurs pour les périodes préquaternaires. Cette thèse présente trois cas d’étude correspondant à des périodes clés de l’évolution de la famille des Noëlaerhabdaceae, qui comprend les ancêtres cénozoïques des producteurs actuels d’alcénones. La comparaison entre le contenu en alcénones (distribution et concentrations) et les abondances relatives et absolues des différentes espèces de Noëlaerhabdaceae dans des sédiments marins datant de l’Eocène-Oligocène (35-31 Ma), del’Oligocène-Miocène (25-16 Ma) et du Pliocène supérieur (3,6-2,6 Ma) montre que,contrairement aux hypothèses précédentes, Reticulofenestra n’était pas le seul genre responsable de la production d’alcénones au Cénozoïque. Les résultats démontrent également qu’il est essentiel d’identifier avec précision les producteurs et la taille de leur cellule pour les estimations de pCO2. Au contraire, l’identification formelle des producteurs ne semble pas indispensable pour obtenir des estimations de températures cohérentes. / Alkenones have been widely used as proxies for the reconstruction of sea surface temperatures and of partial pressure of CO2 (pCO2) in ancient periods. In modern oceans, these long-chain ketones are mainly produced by the coccolithophores Emiliania huxleyi and Gephyrocapsa oceanica. However, there is a huge gap between the first record of alkenonesin the Cretaceous (~120 Ma) and the first occurrence of the modern alkenone producers (< 2Ma). Thus, it seems crucial to identify ancient alkenone producers to ensure the applicability of environmental proxies based on these biomarkers in pre-Quaternary sediments. In this PhD thesis, three case studies are considered corresponding to key periods in the evolution history of the Noelaerhabdaceae family, which includes the Cenozoic ancestors of modern alkenone producers. The comparison between alkenone contents (distribution and concentrations) andNoelaerhabdaceae species-specific relative and absolute abundances in marine sedimentsdating back to the Eocene-Oligocene (35-31 Ma), the Oligocene-Miocene (25-16 Ma) and thelate Pliocene (3.6-2.6 Ma) shows that, contrary to common assumptions, Reticulofenestra was not the only genus responsible for alkenone production during the Cenozoic. Results also underscore the importance of a careful identification of alkenone producers and of their cellsize for pCO2 reconstructions for pre-Quaternary periods. On the contrary, the identificationof producers does not seem essential to obtain consistent paleo-temperature estimates.

This work considers the impact of fast reactor fuel cycles on the UK's nuclear waste inventory, focusing on the disposition of the UK's plutonium stockpile and spent fuel from new build nuclear reactors. Reprocessing spent fuel from nuclear reactors has led to a large stockpile of civil plutonium in the UK. At the end of reprocessing the stockpile was estimated to be 112 tonnes. This large stockpile of separated plutonium poses a proliferation concern and there is no strategy at present for UK plutonium disposition. The NDA's position paper in 2014 stated the re-use of plutonium in a reactor as a preferred option. These options included Mixed OXide (MOX) fuelled Pressurised Water Reactors (PWR) and the use of plutonium in a Sodium-cooled Fast Reactor (SFR), PRISM, operated as a once-through plutonium burning fast reactor. As yet a preferred option has not been selected by the government. Nuclear power is the UK's largest source of low-carbon electricity. Current plans aim to build 16 GWe of new reactors by 2050 to replace the UK's current fleet. This work considered PWR MOX and once-through SFRs for UK plutonium disposition, comparing their relative merits to the direct disposal of the plutonium stockpile in a geological repository. The waste performance of disposition options were compared using assessment criteria based on: Technology Readiness Level (TRL), final stockpile mass, repository size and radiotoxicity. To maximise the reduction of the UK's plutonium stockpile, closed SFR fuel cycles were also considered with scenarios aimed at improving waste performance. Once-through and closed SFR fuel cycles were also considered for the disposition of spent fuel from new build reactors. Research presented in this thesis shows that UK waste disposition options are highly dependent on fuel cycle operating parameters. In once-through plutonium disposition options all scenarios increased repository size compared to direct disposal. Once-though SFRs increased repository size the least, where as PWR MOX reduced the stockpile mass most significantly. The most significant improvement in waste performance, using a closed fuel cycle up to 2150, required short reprocessing times and americium reprocessing. There were no additional improvements of significance with curium reprocessing and the choice of metallic or MOX fuelled SFRs had little impact on waste performance. Preferred fuel cycle scenarios are dependent on the priority given to different assessment criteria. To compare fuel cycle scenarios on an even basis, decision analysis methods were presented using assessment criteria results from the fuel cycles modelled in this work. Decision analysis methods were designed so that the reader can apply their own priorities, through the use of weightings, to the assessment criteria to determine preferable fuel cycle scenarios.

In order to achieve the reductions in emissions that nowadays our planet urgently needs, the collaboration of citizens is necessary. It is necessary that citizens consume products and services that sustainably reduce indirect emissions, but also it is necessary that citizens reduce their associated direct emissions, through the use that they make of their time. In this Thesis, a study is carried out on the direct carbon emissions produced by UK citizens in 2005. These emissions are those emitted when citizens carry out certain daily activities in their households. Later, a comparison with the results of total emissions that other studies obtained is done, to show the importance of the direct emissions derived by this Thesis. This is done first for an average UK citizen, and then the variations in the time use between men and women in each daily activity are analyzed, as well as age ranges, to examine how these variations affect emissions. A relationship between direct and total emissions is found, as well as a gender role issue and a household labor role issue, which produce variations in emissions produced by women and men, as well as variations in emissions associated with different age ranges. In the discussion, the implications of the results obtained in this Thesis are explored, both individually and collectively within the social and economic structure, as well as certain changes that can be introduced daily to achieve a reduction in the direct carbon emissions. “This document presents results drawn from the Multinational Time Use Study (MTUS), but the interpretation of this data and other views expressed in this text are those of the author.

För att minska dessa utsläpp är medborgarna en viktig roll och deras samarbete är nödvändigt. Detta arbete undersöker de direkta koldioxidutsläppen som uppstår i vardagslivet för de brittiska medborgare under år 2005. Resultaten jämförs med tidigare studier som utförts på brittiska medborgare och som analyserar både direkta och indirekta utsläpp. Detta arbete analyserar både utsläppen från en genomsnittsmedborgare i Storbritannien men undersöker även de skillnader som finns mellan kön och olika åldrar. Hur lång tid de olika grupperna spenderar på olika aktiviteter i hemmet skiljer sig åt och även hur mycket arbete de bidrar till i hemmet. Detta har tagits med i beaktning och koldioxidutsläppen från de olika rollerna analyseras. Det var möjligt att dra slutsatser mellan direkta och de totala utsläpp, det var också möjligt att se en variation av utsläpp orsakade av de olika kön och inom olika åldersintervall. I diskussionen genomförs analysen av individuella och kollektiva utsläpp inom den sociala och ekonomiska strukturen. Där förs även en diskussion om vilka förändringar som kan införas i vardagen för att minska koldioxidutsläppen.
