An economic analysis of human cost in armed conflicts.
Get PDFThis thesis seeks to analyse military and civilian loss from violence during contemporary armed conflict in order to facilitate understanding of the evolution of war and its impact on human behaviour. It comprises four chapters; the first two concentrate on the 2033 Iraq War whilst the last two are focused upon global armed conflict during the recent past. Chapter 1 explores how and to what extent military deaths during the Iraq war affect US domestic opinion, proxied by various poll questions concerning war-related issues.
Having addressed irregular frequencies of poll data that restrict time series application, this chapter renders a fresh perspective on casualty-opinion research, suggesting that cumulative military casualties prior to the poll did not have an immediate effect on the poll respondents' opinion regarding the continuation of military actions in Iraq, Instead, respondents are influenced by marginal casualty information from the previous time period, implying a slow adjustment in forming opinion through the Error Correction Mechanism (ECM).
Chapter 2 presents a comparative analysis to gauge any different standards between the US department of Defense and the media in counting violent civilian deaths during the Iraq war. In spite of substantial discrepancies during the initial period of the war, non-parametric tests corroborate that the US military authority and media reports had a non-differential approach towards counting violent civilian deaths during the war period across the spatial and spatiotemporal dimensions. However, the conspicuously conservative count by the US military authority during the initial stage of the war may have hindered the US forces' ability to predict and prepare for the subsequent escalation of violence that brought about large-scale human loss as well as the prolongation of the war which lasted more than 7 years.
Chapter 3 analyses to what extent warring actors intentionally used lethal force against civilians, through the employment of a Civilian Targeting Index (CTI), a newly invented measure to indicate the intensity of civilian targeting for each actor. Building upon Chapter 3, Chapter 4 further examines factors that lead to warring actors targeting civilians as opposed to engaging in battle with war combatants. A dynamic panel approach shows that an increase in the degree of civilian targeting in the previous year further intensified civilian targeting in the current year for the actors involved in prolonged armed conflict
Curating Science in an Age of Empire: Kew's Museum of Economic Botany
Get PDFThis thesis considers the history and significance of the Museum of Economic Botany at the Royal Botanic Gardens, Kew, focussing especially on the period from its opening in 1847 to the eve of the First World War. Looking specifically at the Museum’s collection of wood specimens and artefacts, it seeks to understand the nature of economic botany during this period, and to evaluate the contribution made to the field by the Kew Museum. Through examination of the Museum’s practices, networks, spaces, and objects, it sets out to address the question: how do museums produce scientific knowledge? Part One sets the context. Chapter One provides a brief historical account of nineteenth-century economic botany and the Museum. Chapter Two offers a critical overview of literatures on Kew and economic botany; on the role of place in the production, circulation, and reception of scientific knowledge; and on the role of the public museum in Victorian science and culture. It also outlines the conceptual framework of the thesis. Chapter Three presents an account of the methodology and sources. Part Two highlights museum practices. Chapters Four to Six are devoted respectively to the practices of ‘exhibition’ (the spatialities, rhetorics, and rationalities of display); ‘instruction’ (the educational uses of museum objects); and ‘supply’ (the circulation of objects). Part Three turns to specific objects and their biographies. Chapters Seven and Eight trace respectively the production, circulation and reception of a totem pole from British Columbia and a timber trophy from Tasmania, to demonstrate how objects acquire diverse meanings in diverse contexts, and how they are used to impart meaning to particular sites. In conclusion, Chapter Nine reflects on the cumulative findings of the thesis and on its potential outcomes, and it looks beyond the thesis to recommend areas for future research and practice
Tectono-Stratigraphic evolution of the Barremian-Aptian Continental Rift Carbonates in Southern Campos Basin, Brazil
Get PDFThe southern Campos Basin comprises syn- and post-rift strata characterised by thick and extensive units of non-marine limestones. These carbonate platforms are scientifically significant due to their unusual palaeoenvironmental setting, and the complexity of the factors controlling their accumulation. They are of economic importance due to discoveries of giant hydrocarbon accumulations in these non-marine carbonate rocks.
3D seismic interpretations show an oblique extensional rifting system that formed a series of graben, half-graben, accommodation zones and horsts oriented NESW to NNE-SSW. The area is subdivided into three tectonic domains based on structural style, stretching factors and subsidence rates. The structural template of the syn-rift exerts a strong influence on depositional patterns. Core logging and thin-section work together with FMI and sidewall core
data indicate proximal to more distal lacustrine carbonate deposits with fluvio-deltaic clastics in marginal areas. The dominant carbonate facies are molluscan rudstones and floatstones and a taphonomic analysis (taphofacies) of the cored intervals and exposure surfaces indicate accumulation in shallowing-upward cycles in response to changes in lake level. Microbialite facies, Aptian in age, appear to occur in the most distal locations in restricted palaeoenvironmental conditions. Facies models are presented for the skeletal, mollusc-rich deposits of the Barremian Coqueiros Formation and the overlying microbialite-rich Aptian Macabu Formation.
The deposits are stacked in a hierarchical arrangement of four levels of cyclicity ranging from the entire rift basin fill to metre-scale cycles. Controls on formation of these cycles include structural setting, climate and lacustrine margin progradation. Different types of carbonate platform form in the different basinal settings and include footwall areas of fault-blocks, accommodation zones and buried horst blocks.
The southern Campos Basin evolves from an initial alkali lake (Barremian) to a main phase of syn-rift, brackish lake conditions. The post-rift succession (Aptian) is characterised by both brackish and hypersaline conditions
An Identity for Kernel Ridge Regression
No full textThis paper derives an identity connecting the square loss of ridge regression in on-line mode with the loss of the retrospectively best regressor. Some corollaries about the properties of the cumulative loss of on-line ridge regression are also obtained
Effectiveness and cost-effectiveness of a novel, group self-management course for adults with chronic musculoskeletal pain: study protocol for a multicentre, randomised controlled trial (COPERS)
Get PDFIntroduction: Chronic musculoskeletal pain is a common condition that often responds poorly to treatment. Self-management courses have been advocated as a non-drug pain management technique, although evidence for their effectiveness is equivocal. We designed and piloted a self-management course based on evidence for effectiveness for specific course components and characteristics. Methods/analysis: COPERS (coping with persistent pain, effectiveness research into self-management) is a pragmatic randomised controlled trial testing the effectiveness and cost-effectiveness of an intensive, group, cognitive behavioural-based, theoretically informed and manualised self-management course for chronic pain patients against a control of best usual care: a pain education booklet and a relaxation CD. The course lasts for 15 h, spread over 3 days, with a –2 h follow-up session 2 weeks later. We aim to recruit 685 participants with chronic musculoskeletal pain from primary, intermediate and secondary care services in two UK regions. The study is powered to show a standardised mean difference of 0.3 in the primary outcome, pain-related disability. Secondary outcomes include generic health-related quality of life, healthcare utilisation, pain self-efficacy, coping, depression, anxiety and social engagement. Outcomes are measured at 6 and 12 months postrandomisation. Pain self-efficacy is measured at 3 months to assess whether change mediates clinical effect. Ethics/dissemination: Ethics approval was given by Cambridgeshire Ethics 11/EE/046. This trial will provide robust data on the effectiveness and cost-effectiveness of an evidence-based, group self-management programme for chronic musculoskeletal pain. The published outcomes will help to inform future policy and practice around such self-management courses, both nationally and internationally. Trial registration: ISRCTN24426731
Research utilisation or knowledge mobilisation by health managers: Synthesising evidence and theory using perspectives of organisational form, resource based view of the firm and critical theory
No full textThe literature review builds on an earlier Scoping Review of the literature on knowledge mobilization (Crilly et al, 2010; Ferlie at al, 2012) which identified a gap in the healthcare literature and proposed work in three defined areas or domains. The first is Resource Based View of the Firm, a strategic management concept that examines how differences in capabilities, including knowledge, allow one firm to outperform another. There is no equivalent in healthcare. It states that strategic resources that are valuable, rare, difficult to imitate, and able to be exploited by organizational processes (VRIO principles), will give the firm a sustainable competitive advantage. The second is termed the Critical Perspective, concerned with power and authority in the workplace, which is alive to tensions between occupational groups such as doctors and managers. Two strands of particular interest are Foucauldian and neo-Marxist labour process critical theories. The third area is organizational form, which considers whether certain types of organization, such as networks, are better than others at mobilizing knowledge
A Penrose polynomial for embedded graphs
Get PDFWe extend the Penrose polynomial, originally defined only for plane graphs, to graphs embedded in arbitrary surfaces. Considering this Penrose polynomial of embedded graphs leads to new identities and relations for the Penrose polynomial which can not be realized within the class of plane graphs. In particular, by exploiting connections with the transition polynomial and the ribbon group action, we find a deletion-contraction-type relation for the Penrose polynomial. We relate the Penrose polynomial of an orientable checkerboard colourable graph to the circuit partition polynomial of its medial graph and use this to find new combinatorial interpretations of the Penrose polynomial. We also show that the Penrose polynomial of a plane graph G can be expressed as a sum of chromatic polynomials of twisted duals of G. This allows us to obtain a new reformulation of the Four Colour Theorem
