1	Made in Italy Mölne, Hanna, Lamm, Stina January 2013 (has links) This paper investigates how professionals within the Italian fashion industrycollaborate and communicate to develop the nation brand Made in Italy. Theproblem of brand confusion, which occurs when the different parties within anation does not cooperate towards a distinct brand message, is analysed.Based on a theoretical review of previous studies in nation branding,interviews and observations in the area of Florence and a desk study ofscientific papers, articles and literature, the model “The Nation Brand Tree”was developed. This was applied to the case of Made in Italy. Conclusions: Thecertification “100% Made in Italy” was proven to be an ineffective solution ofsaving the Italian heritage of craftsmanship and quality. The Italian nationbrand is currently being preserved by private investors, but there is a need forincreased governmental support to create a stronger and unified nation brandfor Made in Italy. / Program: Textilekonomutbildningen Italian fashion industry Made in Italy Nation branding Craftsmanship Delocalisation Griffe Country-of-Origin Starlight Effect Made in Economics and Business Ekonomi och näringsliv

3	Spatial Dynamics of Wave Packets in Semiconductor Heterostructures / Räumliche Wellenpaketdynamik in Halbleiterheterostrukturen Meinhold, Dirk 11 June 2005 (has links) (PDF) This thesis presents the first study of the damping of a Bloch oscillating wave packet by Zener tunneling to above-barrier states [1]. We investigate the time evolution of an below-barrier subband Wannier-Stark wave packet in a strongly coupled GaAs/AlGaAs superlattice (SL) with shallow quantum well barriers by optical interband spectroscopy. We use a sub-100 fs homodyne pump-probe technique which is sensitive to the intraband polarization. The presented experimental data unambiguously show an electric field-dependent continuous decrease of the intraband coherence time. Besides the continuous field-induced damping of the intraband polarization, we observe the signature of resonant Zener tunneling of a Bloch oscillating wave packet between discrete states belonging to below and above-barrier bands. This coupling manifests itself as a revival of the intraband polarization [2]. The experiment is modelled in two aspects. First, in a 1D single-particle calculation the wave functions the BO wave packet is composed of are derived. Here, the inter-subband dynamics are found to be given by the energetic splitting between nearly-degenerate below and above-barrier states. The wave packet tunnels from the below-barrier band to the above-barrier band while remaining coherently oscillating. At this time, it is spatially spread over more than 100 nm...
