La fin des temps glaciaires est une période de changement. À l’ouverture de nouveaux territoires, jusque-là prisonniers des glaciers, succède une phase de recolonisation par la végétation, la faune et, enfin, par l’homme. C’est ce qui s’est passé dans les Alpes du nord françaises. Cette étude s’intéresse à l’évolution des sociétés magdaléniennes et aziliennes et, plus particulièrement, aux transformations des industries lithiques ainsi qu’à la signification paléohistorique de ces changements. Les séquences tardiglaciaires de l’abri de La Fru (Saint-Christophe-la-Grotte / Savoie) constituent un corpus de choix pour mener une réflexion de cet ordre. Ce travail, qui intègre les aspects technologiques, typologiques et économiques des industries lithiques, permet de confronter les résultats obtenus sur une douzaine d’ensembles archéologiques, à ceux des ensembles actuellement les mieux documentés des régions limitrophes. En plus de renouveler considérablement nos connaissances des sociétés tardiglaciaires des Alpes du nord françaises, secteur encore méconnu malgré son indéniable potentiel documentaire, cette étude permet de s’interroger sur les conditions d’apparitions des innovations qui marquent les sociétés magdaléniennes, puis aziliennes, entre 14 000 et 11000 ans avant le présent, et, plus généralement, de leur périodisation dans une perspective diachronique. / The end of glacial time is a period of change. The opening of new territories, prisoners of the glaciers during the last glacial maximum, is followed by a stage of recolonisation by vegetation, fauna and finally man. It is the case with the northern French Alps. This study focuses on the evolution of Magdalenian and Azilian societies and more specifically on the transformation of lithic industries and on the palaeohistoric meaning of these changes. Late glacial sequences at La Fru rock shelter (Saint-Christophe-la-Grotte / Savoie) constitute a first-rate corpus to reflect on this issue. This work, which integrates the technological, typological and economical aspects of lithic industries, allows confronting results obtained from on a dozen of archaeological groups, to those currently best-documented groups located in bordering regions. Other than renewing considerably our knowledge of late glacial societies of the northern French Alps, a sector still misread in spite of its indisputable documentary potential, this study allows to wonder about the conditions of the appearance of the innovations which mark the Magdalenian and Azilian societies between 14,000 and 11,000 years before present, and more generally of their periodisation in a diachronic perspective.

Det faktum att grafiska formgivare behöver använda sig av medieteknik i arbetet varje dag indikerar att technostress kan påverka deras yrkesutövning. Den här uppsatsen handlar därför om i vilken grad technostress upplevs hos grafiska formgivare i mediebranschen. Uppsatsens syfte är att öka helhetsförståelsen om hur technostressen kan yttra sig i förhållande till denna yrkesgrupps kommunikation samt produktion genom användande av medieteknik. För att klargöra vad det är som stressar grafiska formgivare kommer studien att diskutera vilka olika stressfaktorer som kan upplevas vid användning av deras medieteknik. De olika stressfaktorer som kan uppstå genom användning vid medieteknik kallas för techno creators. Studien avser därför att synliggöra vilka techno creators som kan förekomma/upplevas mest i deras produktionsprocess. Genom kvalitativa intervjuer tillsammans med fem grafiska formgivare i Malmö har studien genomförts med en induktiv ansats. Empirin samt teorin har analyserats med varandra varpå frågeställningarna besvaras i slutsatsen. Studien tyder på att två av fem techno creators upplevs hos fem formgivare i Malmö. / The fact that graphic designers need to use mediatechnology in their everyday work indicates that technostress can affect their professional practice. This study therefore aims how much technostress is experienced by graphic designers in the mediaindustry. The purpose of this thesis is to increase the overall understanding of how the technostress expresses itself through their communication and producing when they use their mediatechnology.To clarify what stresses graphic designers, the study will discuss which different stressfactor that can occur when they use their mediatechnology. The various stressors that can arise through mediatechnology is called techno creators. The study therefore intends to aim which techno creator that can occur or are the most experienced in their workprocess.Through qualitative interviews with five graphic designers in Malmö, the study has been conducted with an inductive approach. The empire and the theory have been analyzed with each other, and the research question has been answered in the result. The study points out that two out of five techno creators are experienced by five designers in Malmö.

Frågeställningen behandlar hur tempo i bakgrundsmusik påverkar lyssnaren när denne spelar arkadspel. Den grundar sig i tidigare forskning om bakgrundsmusik och dess effekt på koncentrationsförmågan. Bakgrunden innehåller en kort historisk överblick om elektronisk dansmusik och datorspelsmusik. En artefakt har skapats utifrån analyser av arkadspel och musik inom genren techno. Artefakten testades på 30 personer mellan 18-30 år gamla. Testpersonerna fick spela ett arkadspel som innehöll bakgrundsmusik av genren techno i olika tempon. Variablerna tid, längd, antal fall och antal objekt upplockade mättes. Variablerna kompletterades med en enkät med frågor om kön, ålder, spelvana och vad testpersonen hade för åsikt om bakgrundsmusiken. Resultatet visade på att de som spelade med långsammare tempo klarade spelmomentet långsammare i genomsnitt än de som hade snabbare tempo. Slutsatsen drogs att tempo i bakgrundsmusiken påverkar hur snabbt lyssnaren klarar av ett spelmoment. En utveckling av arbetet är att inkludera en större grupp testpersoner och en mer välutvecklad artefakt för ett mer tillförlitligt resultat.

The wave and tidal energy sectors have received much interest in recent years, from policy-makers attentive to the prospect that ocean energy technologies could be capable of contributing towards meeting environmental targets; from utility companies that expressed interest in developing, constructing and operating array projects to export large quantities of clean energy from ocean based resources; and from Small to Medium Enterprises (SMEs) and large multi-national Original Equipment Manufacturers (OEMs) that were interested in undertaking technological development to commercialise wave and tidal energy converters that could successfully harness the energy contained within the ocean waves and tides. Within the existing research, development and innovation environment that has largely dominated the development of wave and tidal energy to date – rapid development of large MW-scale devices capable of utility scale power generation – technology developers have failed to reach the level of deployed capacity that was initially anticipated, despite the significant level of investment that has taken place. Indeed, the expected contribution of ocean energy in the wider energy mix, which has been written into policy documentation at both national and European level, has so far failed to materialise in the form of prolific multiple device array deployments. The research, development and innovation environment has not delivered on its intended objective of demonstrating commercial technology readiness, and the historic development trajectories for ocean energy technologies may not represent the most cost-effective route to product commercialisation. This research explores the wave and tidal energy research, development, and innovation environment through extensive stakeholder engagement within the ocean energy sector, and through application of suitable techniques from innovation theory. The purpose of this research was three-fold. Firstly, an objective analysis of the development of the wave and tidal energy sectors – building a comprehensive understanding of their development to date through extensive stakeholder engagement, and comparing wave and tidal energy technology development with that of historic energy technologies that have successfully entered into commercial operation – was necessary in order to identify whether the attempt by ocean energy technologies for rapid up-scaling of technology is consistent with the development pathway that was followed by energy technologies which have successfully transitioned from novel invention to full commercial operation. This work identified several dichotomies that are present in the nascent stages of technology development in the wave and tidal energy sectors. Secondly, the uncertainties surrounding existing capital and revenue costs, and the uncertainties within the potential future cost reductions associated with current technology trajectories, could lead to unsustainable investment requirements. Commercialisation of wave and tidal energy technology is predicated upon significant cost reduction – the current technology costs are not feasible for large scale roll out of technology. A research focus on the economic uncertainty through application of learning theory and a learning investment sensitivity analysis was anticipated to demonstrate the economic impact of minor perturbations from idealised reference assumptions. The results from this work suggest that even minor perturbations in input parameters have substantial negative impact on overall investment requirements to bring technology to a level of cost competitiveness. Thirdly, the policy landscape surrounding wave and tidal energy development has not been specifically compared and contrasted, using a number of performance metrics, to a technology which was subject to similar expectations in the form of income streams – wind energy technology. The causes and motivations for the rapid transition to large-scale technologies and ‘accelerated innovation’ within ocean energy technology were considered within this research, which suggested that a mismatch between policy support and technological readiness could misguide and misdirect the innovation pathway, harming the commercialisation prospects of ocean energy technology. In order for the successful emergence of economically sustainable wave and tidal energy technologies, a paradigm shift may be necessary, a change from the current approach that has to date dominated technological development within both the wave and tidal energy sectors. This research draws together industry consultation with academic insight to identify an optimised innovation pathway, culminating in a policy appraisal to guide and inform economically sustainable development of wave and tidal energy technologies.

Projektet handlar om hur jag har lärt mig grunderna för att kunna DJ:a techno. Detta innebär bland annat att i realtid överlagra och sammanfoga ljudkällor för att skapa en musikalisk helhet. Under denna process har jag lärt mig om olika mixningstekniker, hård- och mjukvara, repertoar samt både DJ:andet och technons historia. Detta har i sin tur väckt tankar om hur jag i framtiden kan använda DJ:ande som ett redskap inom musikundervisning och som ett yrke. Projektet har konkret resulterat i en mixtape som finns tillängligt via det tryckta exemplaret samt en spelning på en privat fest.
