Zirconocene mediated co-cyclisation reactions
No full textThe novel work in this thesis covers three quite different areas of organozirconium chemistry.The first is the synthesis of oxacycles by zirconocene mediated co-cyclisation, of which the literature contains few examples. 1,7-Enyne substrates based on alkoxyalkynes cyclise in good yield to provide tetrahydropyrans. The presence of an exocyclic, tethered alcohol functionality in the cyclised product allows a second, acid catalysed cyclisation to occur, providing a novel route to spiroketals.In the second area, the feature peculiar to the zirconacycles prepared is a leaving group β to zirconium. In all cases, elimination of Zr-leaving group occurs to provide an alkene. Where the cyclisation substrates are 1,6-dienes or enynes prepared from dihydrofuran, cyclisation occurs despite the hindered nature of the enol ether double bond. Where the substrates are prepared from ethyl vinyl ether, the enol ether double bond is disubstituted, and a wider variety of 1,6-dienes and -enynes can be cyclised in yields of up to 89%. Chiral centres in the substrate often induce excellent diastereocontrol of the newly generated methyl group. The important feature of the cyclisation products is an exocyclic methylene group. As these methylene cyclopentanes are difficult to prepare from terminal alkyne substrates, our methodology provides an excellent route to these compounds. The cyclisation products are also monoalkyl zirconocenes, which we wished to functionalise further using carbenoid insertion chemistry. We have shown that ethoxy groups on zirconium inhibit carbenoid insertion, whereas chloride groups allow vinyl carbenoid insertions to occur in yields of up to 75%.The third area of research was an attempted total synthesis of the natural product mucosin, whose structure contains a bicyclo [4.3.0] nonane unit with four contiguous stereocentres. We prepared a co-cyclisation substrate which precedent suggested would provide only the desired diastereomer of the bicycle and a handle for introduction of the remainder of the natural product skeleton. Unfortunately, the co-cyclisation provided a mixture of products. Investigation was made into dihydro and despropyl analogues, which we hoped would provide single products on co-cyclisation. Although the synthesis was not completed, we have laid down groundwork which we hope will lead to a successful completion at a later stage.</p
Being political and the reconstruction of public discourse: Hannah Arendt on experience, history and the spectator
No full textThis study analyses a number of Hannah Arendt’s books and essays written over fourdecades and suggests that a common thread can be detected that links together thedifferent stages of her thought. The need to do this follows from having to treat withcaution Arendt’s own judgement that in the mid-1930s her thinking changed when shebecame political. In relation to writings she produced throughout her life, what can beseen is that she was actually preoccupied by one and the same question, namely, whatit means to be with other people, she just looked for answers in different places andused different methods. The study shows how in her dissertation on Saint Augustine’streatment of love and such early published pieces as ‘The Enlightenment and theJewish Question’ and her commentary on Rilke’s Duino Elegies, Arendt was alreadychallenging Heidegger’s ontology, in Being and Time, of ‘being-with-one-another’.Her thinking at this time was purely empirical though, dependent upon interpretationsof history alone. Her later work, The Origins of Totalitarianism and The HumanCondition, for instance, reveal that Arendt’s political conversion amounted to therealisation that ontology and history are as necessary to each other as Kant’s conceptsand intuitions. Her defence of plurality therefore, represented both a reaction to theevils of totalitarianism on the grounds that it is an anti-political form of government,and a revised challenge to Heidegger’s assessment of das Man on his own terms. Inaddition though, Arendt’s depiction of public space and public discourse, suggestedthat choosing to be with others politically, is an antidote to the solitude of theindividual engendered by mass society

Texturalism and Performance - Adorno's Theory of Truth
No full textThis thesis establishes a new reading of Adorno’s theory of truth. I argue that Adorno posits truth as being mutually constituted by dialectical philosophical texts, and the agent’s cognitive engagement and ‘performance’ of these texts. This reading is founded on an interpretation of Adorno as a transcendental philosopher, who grounds the transcendental necessity of concepts in the requirements of self-preservation. The agent’s performative interaction with the text is held to provide access to truth by virtue of interfering with the conceptual mediation of the agent’s experience.
I go on to argue that this conception of truth is also at play in Adorno’s philosophy of art. I claim that the artwork, for Adorno, presents a dialectically constituted whole which, when performatively engaged with by the agent, disrupts the conceptual mediation of his or her experience, and provides access to the truth. While I show that Adorno considers his theory of truth content for art and philosophy to be unified, I also demonstrate that Adorno nonetheless maintains the differentiation between art and philosophy. I do this by providing a new interpretation of the relationship which Adorno draws between aesthetic autonomy and heteronomy
Deception and Britain's road to war in Iraq
No full textEver since the 2003 invasion of Iraq, there has been a widely shared public perception in the UK and beyond that the British government lied in making the case for war. One major theme has been the view that the Blair government lied about the strength of the intelligence about alleged Iraqi weapons of mass destruction (WMD) and the extent of the WMD capabilities claimed by that intelligence. A second theme that has received less attention has been the view that the Blair government lied in claiming that its actions at the United Nations (UN) were aimed at securing peaceful Iraqi compliance with its disarmament obligations. Instead, most think that the UK was actually committed to a policy of regime change by force and did not want the ‘UN route’ to produce a peaceful outcome. The article argues that the conceptual focus of the discussion needs to be broadened from lying to also considering deception by omission and deception by distortion as part of a campaign of organized political persuasion. It argues that, on the WMD intelligence, it is now apparent that a campaign of deceptive organized political persuasion was conducted by UK officials. With respect to the UN route, there is mounting evidence that the Blair government ran a campaign of deception on this issue as well to pave Britain’s road to war in Iraq
The Five-Valve C Trumpet: History, Design, and Advantages
No full textabstract: Since 1913, some of the world’s finest trumpeters have utilized the advantages of
specialized custom trumpets that can be played in multiple key centers through the operation of additional valves and slides. Merri Franquin (1848-1934), a leading trumpet teacher in twentieth-century Paris, patented two multiple-key trumpets: a four-piston- valve model that plays in the keys of C and D, and a five-piston-valve model that plays in the keys of A, B , C, and D. Thibouville-Lamy (1867-1969), a now-defunct French instrument company, built both models by adding extra valves and slides to three-valve C trumpets.
In the mid-1900s, top performers such as Roger Voisin, Armando Ghitalla, and David Hickman began using similar trumpets in performances and recordings. Regrettably, only a privileged few have had access to these instruments and the numerous advantages that they can provide. Thus, by reviewing and building upon current data on multiple-key trumpet design and performance, the author aims to unlock a vast potential for performance enhancement, waiting to be tapped by current and future trumpet performers.Dissertation/ThesisDoctoral Dissertation Music 201
Implementing the market approach to enterprise support - an evaluation of ten matching grant schemes
No full textDeveloping viable new business is critical to recovery, and long-term growth, especially in transition economies. There has been a long history of public support of enterprise development, starting with centralized state agency initiatives, but moving more recently to decentralized instruments for development of the business services market. The window of time during which the benefits of intervention are likely to be greatest: when a market is in its infancy, and its development is constrained by uncertainty, and lack of information. Interventions for enterprise support should be demand-responsive, and flexibly organized. In some circumstances, centralized assistance may still be effective, but it is generally better to use competitive private service providers responding to enterprises'changing needs. The main task is to stimulate the private services sector, improving its capacity to respond to the demands of new, and expanding private enterprises. Support for enterprises has tended to be either free, or heavily subsidized. But such subsidies can be justified only if interventions efficiently supply goods. Providing technical, and management know-how can be a public good if it generates externalities- if, for example, know-how benefits can be disseminated at proportionately low additional cost. Any subsidy for an intervention should be temporary, and should be phased out when the main objective of intervention is achieved - that is, when the market takes off. Grants should generally be for know-how, not for equipment. There may be a case for unbundling the know-how component of loans (including feasibility studies, and follow-up expert services) for grant funding. A package combining loans and grants - through a single financial institution, or through separate institutions - may work provided safeguards can be put in place to prevent perverse use of grants. The matching grant model, which is used increasingly in the World Bank, and elsewhere, is one solution - but it must be justified, and carefully designed. After evaluating ten matching grant funds, the author concludes that performance is mixed. Best practice models are needed. Ensuring economic benefits requires proactive management, with clear objectives of market facilitation ("making a market"). And it requires a balance between rapid grant approval procedures, and careful selection of services for grants.Economic Theory&Research,Decentralization,Enterprise Development&Reform,Environmental Economics&Policies,Banks&Banking Reform,Health Economics&Finance,Banks&Banking Reform,Economic Theory&Research,Environmental Economics&Policies,ICT Policy and Strategies
Biographies of the Most Influential Twentieth Century Trumpet Players in Asia
No full textabstract: ABSTRACT:
The research for this paper is intended to introduce the reader to many of the influential trumpet performers and pedagogues in East Asian countries and territories along the Western Pacific Ocean Rim, including China, Hong Kong, Japan, the Philippines, Singapore, South Korea, Taiwan (R.O.C.), Thailand, and Vietnam.
Shao-Chun Tsai, the author of this research paper, finds it important for musicians to recognize that they are often influenced by other musicians in addition to their own efforts and self-discovery of who they are as artists. The author is a trumpeter and pianist from Taiwan, and would like to acknowledge the many outstanding trumpet players from Asia that have made important contributions to the discipline of trumpet playing. Unfortunately, there are very limited English resources available for the recognition of these pioneers, and as such they are often unknown to the general public and even to aspiring musicians. By gathering a collection of biographies, the author’s goal is to shed greater light on the rich trumpet playing and pedagogy heritage and influence in this region.
The research information contained within was primarily gathered through personal interviews conducted by the author in order to ensure that the most up-to-date and accurate information was collected for the project. This project studies nine regions and includes thirty-seven trumpeters deemed to be influential by the author, who has invested her best efforts to acquire the most in-depth and current facts obtainable. The author hopes that the stories behind each of these successful musicians will stimulate trumpeters of all ages and inspire them to pursue their own development and goals in music.Dissertation/ThesisDoctoral Dissertation Music 201
