Detta arbetet går ut på att undersöka hur användandet av presets påverkar min arbetsgång när jag mixar låtar i en studio, i vilken utsträckning jag kan använda presets samt om de utvecklar mitt sätt att mixa på. Resultatet blev att presets utvecklar mitt sätt att mixa på och kan, beroende på situationen, effektivisera min arbetsgång.

Synthen är ett instrument vars ljud inte behöver begränsas av dess fysiska form och utseende i samma utsträckning som instrumenten före dess tid. Inte heller är den begränsad till ett signifikant ljud utan har möjligheten att producera en enorm variation av både imitativa som unika ljud. Men med tidens gång har vi etablerat och fastställt vissa etablerade konventioner vid användningen av synthen, underliggande koncepten som tidigare paradigm har skapat inom vår förhållningsätt till den. Syftet med undersökningen är att belysa två etablerade konventioner i synthens användargränssnitt och ljuddesignsfunktion, nämligen klaviatur och förinställda ljud. Detta för att sedan med hjälp av tre djupintervjuer forma en bild av hur några av dagens producenter av elektronisk musik tycker, tänker och använder sig av dessa funktioner. För att ge en referenspunkt till konventionerna som behandlas i intervjuerna har litteratur om synen samt utvecklingen av synthen studerats och satts i kontext med paradigmbegreppet. Resultatet av undersökningen antyder på att konventionerna inte används i dess ursprungliga mening i fallet med de tre informanterna. Dock så letar sig konventionerna in i många av de synthar som informanterna använder sig av. Musikstil påverkar även hur producenterna använder sig av de etablerade konventionerna, Detsamma gäller även i viss mån användandet av synthar i live sammanhang.

In my first chapter, we document and study the use of Rule 10b5 1 preset repurchase plans. We exploit this new and widespread form of payout to examine an issue at the core of payout decisions—the tradeoff between commitment and financial flexibility. Relative to open market repurchases, preset plans provide an expanded repurchase window and increased legal cover, albeit at the cost of reducing repurchase flexibility and the option to time repurchases. These costs and benefits are significantly associated with Rule 10b5-1 adoption. Consistent with preset plans signaling commitment, Rule 10b5-1 repurchase announcements are associated with greater and faster completion rates, with more positive market reactions, and with more dividend substitution than open market repurchases. Lastly, we find that preset repurchase plans represent a unique payout tool whose introduction encouraged a different set of firms to buy back stock and significantly altered the payout landscape. My second chapter examines the strategic use and timing of share repurchases by insiders for personal gain. Using grant level compensation data and a hand-collected sample of monthly repurchases, I find a positive relation between CEO equity sales and share repurchases. I identify the relationship by instrumenting equity sales with equity grant vesting schedules. This relation is persistent across firm characteristics and does not appear to be destroying shareholder value. The results indicate managerial self-interest motivates a subset of share repurchases.

Dagens komplexa vårdmiljö kan förenklas genom att utrusta sjukhusensoperationssalar med en integrerad systemlösning. Syftet är att möjliggöramanövrering av all utrustning från en gemensam enhet, och på så sätt effektiviseraarbetsflödet. Idag saknas data som stödjer påståendet att systemetsförprogrammerade scenarion innebär en förbättring. Det här arbetet går ut på att undersöka den nytta som integrationslösningenmedför i operationssalar. Detta görs genom att undersöka arbetsflödet utifrån treolika styrningsfall (med förprogrammerade scenarion, manuellt via applikationeroch exludering av systemet), samt utifrån tre olika mätparametrar (klick, steg ochtid). Syftet med jämförelsen är att se vilket av dessa fall som är optimalt utifrån ettanvändarperspektiv. Resultatet visar på en tydlig fördel för styrning av systemet med förprogrammeradescenarion utifrån samtliga mätparametrar. De antaganden som har formatundersökningen, samt de kvantitativa begränsningarna i studiens data, tas hänsyntill i analysen. Under analys stärks det framtagna resultatet. I kombination med en fördeladstyrning mellan användarna utgör styrning med förprogrammerade scenarion detbästa alternativet för ett optimerat arbetsflöde. / Healthcare system complexity can be simplified by equipping hospital operatingtheatres with an integrated system solution. The goal is to improve the hospitalworkflow by enabling maneuvering of all the equipment from a common unit.Today there is no data to support the claim that the system offered feature of usingpreset scenes provides any improvements. The aim of this study is to demonstrate the benefits of the integrated operatingsystem. This is done by performing a workflow analysis based on three differentcases (with preset scenes, maneuvered through the applications and without use ofthe integrated system) and three different parameters (clicks, steps, and time). Thepurpose is to clarify the, from a user perspective, most beneficial case. The measured result shows an advantage when using the system with presetscenes. All of the assumptions in the survey, including the limitations ofquantitative data, are considered in the study. The result is validated by the analysis. A combination of the case with preset scenesand a distributed control between the users are therefore the best alternative for anoptimized workflow.

The aim of this study was to investigate the management of in-service education and training (INSET) conducted for teachers, in particular in rural secondary schools in the Zoutpansberg West Circuit, Limpopo Province. The problem was conducted by a literature study and empirical investigation. The literature review explored various definitions of INSET and related concepts and dealt with the provision of in-service training for teachers in developing countries such as Kenya and South Africa and a developed country such as Britain. The empirical study investigated the management of INSET for secondary school educators in rural areas using a questionnaire administered to educators in eleven secondary schools in the Zoutpansberg West Circuit. Findings indicated strengths and weaknesses of INSET. Based on the literature and the empirical investigation, recommendations are made for the Department of Education with regard to the provision of INSET. / Educational Studies / M.

The poor quality of state controlled black education in South Africa in the past was mainly caused by low pupil per capita expenditure and poor teaching. This resulted in many problems. Because of past neglect, as well as the increase in number of children to be educated, black education must be revitalised. Government funding is not adequate, therefore, privatisation and semi-privatisation of education is a recommended solution. Community and business involvement is encouraged, and state control should be reduced. Short-term strategies have been fairly successfully implemented. With a view to proposing strategies for the upliftment of black education, the upgrading of teachers through improved INSET and PRESET Q!_Qfil_~mmes is considered a priority. Already implemented models, such as Promat, TOPS and the Molteno Project should be investigated. These programmes have been successful to varying degrees. Strategies have been proposed based on the above findings and guidelines for further research suggested. / Educational Studies / M. Ed. (Comparative Education)
