Music for classical guitar by South African composers : a historical survey, notes on selected works and a general catalogue
No full textIncludes abstract.Includes bibliographical references (leaves 296-309).This is the first comprehensive investigation of music for, or including, the classical guitar by South African composers. The focus of this research has been, firstly, to uncover as much of the repertoire as possible, and, secondly, to collate, study, catalogue and report on the information. A brief historical survey of the guitar in South Africa provides the context within which this study was conducted. The primary sources of quantitative data collection were through the archival catalogues of the South African Music Rights Organisation and through personal contact with guitarists, composers and guitar teachers. Other sources consulted were publishers, broadcasting corporations, recording companies, libraries and the internet. The body of the dissertation comprises biographical sketches, background notes, analyses and technical notes on 17 selected solo and chamber works dating from 1947 to 2007 by some of South Africa's most prominent composers and guitaristcomposers. The repertoire ranges in style from the traditional and ethnically inspired to the experimental and abstract. As this is an empirical survey, each selected entry includes details on instrumentation, duration, level of difficulty, number of pages, scordatura, commissions or requests, sources or publishers, premières and recordings. A biography of each composer is provided as well as background notes which offer an overview of the selected work. The notes discuss historical, cultural, musical and extra-musical influences, and frequently include references to interview material. The commentaries on the selected works, with musical examples, include an analytical component describing structure, form, stylistic and compositional elements, while the technical observations include performance suggestions and a grading for each work

The Christian Message in a Postmodern World: a critical re-appropriation of Hendrik Kraemer's theology of religions
No full textThis thesis is a critical re-appropriation of Hendrik Kraemer's theology of religions. Part I introduces theology of religions through the now familiar threefold typology: Kari Earth represents 'exclusivism,' Kari Rahner, 'inclusivism,' and John Hick, 'pluralism' (Chapter 1). It then argues that the typology implicitly represents non-pluralist approaches as theologically deficient and ethically insensitive while masking problems in pluralist positions (Chapter 2). It thus releases Kraemer from the typology and from the more emotive charges directed against 'exclusivism.' Part II chronologically and thematically surveys Kraemer's theology of religions, describing his missiological and theological contexts (Chapter 3) and summarising his major works (Chapter 4). The crux of the argument comes in Part III. First, a survey of the contemporary philosophical climate is offered through a summary and critique of Jean-Frangois Lyotard's interpretation of the postmodern condition Subsequently, three theological responses are assessed with Mark C. Taylor's a/theology and John Milbank's theology presented as avoidable extremes while the work of Hans Frei and George Lindbeck is offered as a mediating position which is dubbed 'postmodern orthodoxy' (Chapter 5). Second, after reviewing key themes in Kraemer's position, theological and phenomenological criticisms are outlined and evaluated. Though they do not seriously threaten the position, these criticisms prohibit extreme interpretations of, and lead to slight modifications in, Kraemer's work (Chapter 6). Finally, when re-read through the lenses of postmodern orthodoxy, Kraemer's thought is shown to offer to contemporary theology of religions avenues of theological creativity which are nevertheless faithful to the Christian tradition (Chapter 7). The thesis concludes that Hendrik Kraemer's theology of religions is worthy of critical re- appropriation
Author Functions in Lars Kepler\u27s The Hypnotist: An Analysis
No full textThis paper examines Foucault\u27s notion of the author function as it pertains to Lars Kepler\u27s bestselling 2011 crime thriller, The Hypnotist. Lars Kepler is the pseudonym of a Swedish husband-wife writing duo, making him the perfect subject for analysis centering on illusory notion of the author. This paper will answer these questions: Who is the true author of The Hypnotist? What factors influence the author function of this bestelling novel? And what can The Hypnotist phenomenon tell us about the relationships between authors and their readers? This paper will demonstrate that no literary works may be ascribed to an individual person, and that authors hold no privileged knowledge of the works they produce, because authors cease to be authors the moment pen is lifted from page
An annotated catalogue of selected works for clarinet by South African composers
No full textThe dissertation consists of an annotated catalogue of nineteen selected works for clarinet by South African composers. These are presented in chronological order, based on the year of composition. A short biographyof the composer is given before the work is discussed. Of the analysed works, all those for solo clarinet or for clarinet and piano have been graded. A thesis of a similar nature, written in 1989 by L.A. Hartshorne, entitled ""The Compositions for Clarinet by South African Composers"", contains details of twenty-four works written between 1928 and circa 1981. The majority of the compositions analysed in the current dissertation were written from around 1981 onwards, and to some extent, therefore, this research could be seen as complementary to the information contained in the aforementioned thesis. An addendum lists all the South African works featuring solo clarinet that the author was able to trace. These include solo works, cham ber works for up to nineteen instruments and concerto-type works with strings or orchestra
Portret van twee negentiende-eeuwse meesters: Leven en werk van Hendrik Jan en Cornelis Hendrik van Ameron
No full textLeven en werk van de kunstschilder Hendrik Jan (1776-1833) en diens zoon Cornelis Hendrik van Amerom (1804-1874) zijn nauw verbonden met het kunstonderwijs in Arnhem en Leiden. De vroegste geschiedenis van de Arnhemse Kunstakademie is niet te denken zonder de invloed van Hendrikjan van Amerom. Als "eerste tekenmeester" bepaalde hij dertig jaar lang het onderwijs aan deze instelling. Zijn zoon, Cornelis Hendrik, speelde een belangrijke rol in het tekenonderricht te Leiden, waar hij les gaf aan diverse kostscholen voor jongens en meisjes uit de "betere standen". Cornelis Hendrik van Amerom kan tot de vroegste fotografen in Nederland worden gerekend. Tevens mag hij worden beschouwd als ontdekker van het Gelderse landschap, dat inspiratiebron werd voor vele kunstenaars. Hiermee is hij een directe voorloper van de schilders van de "Oosterbeekse Schildersbent" en de "Haagse School". Van uitzonderlijke (kunst)historische betekenis is zijn "Memorie-boekje". In dit tot nu toe onopgemerkt gebleven ego-document maakte hij belangrijke aantekeningen over zijn familie en zijn werk als kunstenaar en fotograaf. Het "Memorie-boekje" wordt in deze uitgave, met een geïllustreerde oeuvrecatalogus van beide kunstenaars, integraal gepubliceerd. Uitgave van Stichting Leids Kunsthistorisch Jaarboek
Non-equilibrium dynamics of di-platinum complexes and molecular dyes in solution: Insights from transient absorption and two-dimensional Fourier transform spectroscopy
No full textUnraveling the interplay between electronic- and vibrational degrees of freedom on the earliest time scales of physical, chemical and biological processes is crucial to gaining insight into the mechanisms that govern the world around us, since it is during these primary steps that the fate of the excitation energy - be it solar, chemical or physical - is decided. A tiny structural change during the first 10s of femtoseconds can for example predetermine the dynamics of a system over microseconds, and newly developed techniques in time-domain spectroscopy have proved to successfully capture exactly these pivotal mechanisms.
In this thesis I use ultrafast spectroscopy to investigate the non-equilibrium dynamics of a prototypical di-platinum complex. Transient absorption spectroscopy is complemented with transient absorption anisotropy and fluorescence up-conversion to identify the spectral features of the intermediate excited states. The results show that the intersystem crossing from the singlet- to the triplet manifold of states happens on a 0.6 to 0.9 picosecond time scale, slower than previously assumed. As a consequence, the observable coherence is associated with a singlet excited state, rather than a triplet, and dephases prior to the intersystem crossing. The study further illustrates the importance of having a good understanding of the transient spectral signatures and yields insight into the structural dynamics of di-platinum complexes.
In addition, I have built and commissioned a two-dimensional photon echo experiment that is capable of acquiring broadband excitation- and detection frequency resolved transient spectra in the visible with a temporal resolution of approx. 10 femtoseconds. All relevant steps of the development are outlined in this thesis and 2D spectra of four different dye solutions highlight the capabilities of the experiment. The temporal evolution of the 2D spectra of nile blue is analyzed as an example and shows the information content that is contained within the data.LS
Efficiency Gains from Mergers
No full textThe purpose of this discussion paper is to contribute to the analysis of two questions. Should a merger control system take into account efficiency gains from horizontal mergers, and balance these gains against the anti-competitive effects of mergers? If so, how should a system be designed to account for efficiency gains? The report is divided into five separate parts. The discussion paper is based on a report to the European Commission. To help answer the two questions we start with an extensive review of the relevant economic research, including both theoretical and empirical work. Next, we review the current practice in seven O.E.C.D. jurisdictions. Finally, we propose a merger control system, emphasizing the central role of informational limitations. Based on our conclusions from the empirical literature that efficiencies may need to be assessed on a case-by-case basis, we construct an information-economizing two-stage decision framework for evaluating mergers. In a first stage, notified mergers are assessed using routine tools with modest information requirements. Mergers that do not pass the first stage test are subject to further investigation, including an efficiency defence. ZUSAMMENFASSUNG - (Effizienzgewinne von Unternehmenszusammenschlüssen) Das Diskussionspapier leistet einen Beitrag zur Analyse von zwei wettbewerbspolitischen Fragen: Sollen im Rahmen der Fusionskontrolle Effizienzgewinne horizontaler Zusammenschlüsse berücksichtigt und den wettbewerbsbeschränkenden Wirkungen gegenübergestellt werden? Und, falls ja, wie sollten diese Effizienzgewinne im Kontrollprozess berücksichtigt werden? Grundlage für das Diskussionspapier ist ein Gutachten, das für die Europäische Kommission erstellt wurde. Die Untersuchung beginnt mit einer ausführlichen Darstellung der relevanten ökonomischen Forschung. Dabei werden sowohl theoretische als auch empirische Arbeiten berücksichtigt. Anschließend wird die gegenwärtige Praxis der Fusionskontrolle in sieben OECD-Ländern erörtert. Auf Basis der gewonnenen Erkenntnisse wird schließlich ein Verfahren für die Analyse von Unternehmenszusammenschlüssen vorgeschlagen. Das vorgeschlagene Verfahren greift die empirische Erkenntnis auf, daß Effizienzgewinne nicht generell aber fallweise von Bedeutung sein können. Es wird ein zweistufiger Entscheidungsprozess entwickelt, um einerseits die Informationskosten gering zu halten und andererseits die notwendige Präzision des Kontrollverfahrens zu sichern. In der ersten Stufe des Verfahrens prüfen die Wettbewerbsbehörden angemeldete Fusionen anhand von Standardkriterien mit geringen Informationsanforderungen. Nur solche Fusionen, die diesen Test nicht bestehen, werden dann in einer zweiten Stufe einer genaueren Analyse unterzogen, bei der Effizienzgewinne berücksichtigt werden.
”Lärda nyheter” i Peter Hernquists korrespondens till Carl von Linné och Abraham Bäck - med kommentarer och utvikningar
No full textI detta Meddelande nr 55 från Veterinärhistoriska museet har författaren - professor emeritus Lars-Erik Appelgren - gjort ett urval av den korrespondens som Peter Hernquist hade med sina mentorer Carl von Linné och Abraham Bäck under sin vistelse i Frankrike, varvid ”Lärda nyheter” varit en ledstjärna för urvalet. Speciellt har breven till Bäck försetts med författarens personliga kommentarer men även kompletterats med faktaupplysningar från andra källor än breven om berörda nyheter. För att underlätta läsningen har dessa kommentarer omgetts med enkelkonturerad och utvikningarna med dubbelkonturerad ram. Lars-Erik Appelgren har inte bara genom sitt veterinärhistoriska författarskap utan också genom att ställa sina fackliga kunskaper och sin eminenta estetiska läggning till förfogande gjort Veterinärhistoriska museet ovärderliga tjänster. Det är med stor glädje jag noterar att region Uppsala nyligen visat sin uppskattning genom att tilldela Lars-Erik sitt Medicinhistoriska stipendium med motiveringen att de vill ”lyfta fram ett viktigt men ofta förbisett område inom medicinhistorien: veterinärmedicinen”. Med de varmaste gratulationer
Unravelling Drivers of Morphological Change: A Case Study on the Prins Hendrik Sand Dike
No full textFlood defense will have to be strengthened all over the world as sea level rise poses great challenges for the safety of coastal settlements. Strengthening traditional hard flood defenses is becoming increasingly more difficult due to limited space in the coastal zone and large costs inflicted with renovation. Adaptive ‘soft solutions’ pose an alternative as they make use of natural processes that are able to adapt to changing boundary conditions. The Prins Hendrik Sand Dike is a pilot project of such a soft solution placed in front of an existing hard sea dike. The Prins Hendrik Sand Dike is the subject of this research.This research strives to identify the role of waves, currents, and water levels on morphological development of the Prins Hendrik Sand Dike. Which requires an identification of the morphological development during the 3.5 years of service lifetime. This is followed by a characterization of the forcing climate based on measured on-site data. This knowledge is used to hindcast the full forcing climate during the PHSD lifetime and calculate morphological development. Lastly, a comparison of calculated and observed morphological development reveals suitability of engineering formulae on low-energy beaches.Results indicate the spit head develops at a faster rate than predicted in model studies. In addition, constant erosion in the form of coastline retreat is observed in a section that serves as primary sea defense. These findings hamper successful development of habitat and possibly decrease the longevity of the sea defense if maintenance is not performed. Furthermore, waves have been determined to be the dominant forcing mechanism resulting in sediment transport and morphological development. In addition, systematic water level changes that occur under specific wave conditions are identified causing increased Northeastward transport of sediment. These findings likely explain discrepancies between the previously modelled and observed morphological development. Implications of this research contribute to an understanding of the interconnected nature of forcing scenarios at low-energy beaches and can be used to improve modelling efforts of low-energy beaches. Furthermore, it provides a basis for Hoogheemraadschap Noorderkwartier to make decisions on maintenance activities.Prins Hendrik Sand DikeCivil Engineering | Structural Engineering | Hydraulic Structure
