This thesis investigates the impact of the country-of-origin effect on Chinese luxury brands which intend to enter the German luxury goods market. By means of a questionnaire and a quantitative analysis, possible threats to Chinese newcomers that derive from an unfavorable country image are illustrated. In fact, the Chinese origin of luxury goods has an impact on German consumers' perception.
At Zwartbas, about 10 km west of Vioolsdrif, southern Namibia, the Dwyka succession is composed of tillites and distal fossiliferous dropstone-bearing glacio-marine shales. The completely exposed Dwyka succession is interbedded with thin bentonites, altered distal pyroclastic deposits, which were derived from the magmatic arc at the southern rim of Gondwana. Dropstone-bearing and dropstonefree sequences intercalate with four diamictites, of which the two lowest were certainly recognised as tillites. Four events of deglaciation were proven at Zwartbas and thus consist with correlative deposits in southern Africa. Numerous fossilised fishes, trace fossils, and plant fragments appear frequently within the lower half of the Dwyka succession whereas trace fossils were principally found in the complete succession. Although the environmental determination is quite problematic, the fossil assemblage rather implies proximal, shallow water conditions with temporary restricted oxygenation. The hinterland was covered with considerable vegetation, which points to a moderate climate. Water salinity determinations based on shale geochemistry rectify contrary palaeontological results and point to rather brackish or non-marine conditions in comparison to present-day salinites. Geochemical analyses of the bentonites relate the pyroclastic deposits with acid to intermediate source magmas, as they are known from the magmatic arc in present-day Patagonia. Tectono-magmatic comparisons furthermore emphasise a syn-collision or volcanic-arc situation of the magma source. However, significant cyclicity in the production of the pyroclastic deposits was not observed. Radiometric age determinations of two tuff beds clearly date the onset of glacial activity into the Late Carboniferous.
Compared to other countries, China was particularly early in developing a comprehensive set of policies to promote electric mobility (e-mobility). The aim of this study is to examine how China’s e-mobility development – through changes in formal institutions as well as market forces – has affected German passenger car manufacturers and their competitive environment and positions. The study is guided by two strands of research: new institutional economics and strategic management literature. A holistic multiple-case design is used to analyze five German case study firms. Qualitative interview data are collected through interviews and analyzed using a thematic analysis. The results show that the electric transformation in China has been shaped by changes in formal institutions at the macro, meso, and micro levels. Interestingly, the case study firms were affected not only by changes in China’s formal institutions but also by disparities between institutions in China and Europe. Furthermore, the data suggest that German car manufacturers are facing an increasingly competitive environment in China: at least four forces in Porter’s five-forces model seem to have intensified in recent years. The extent to which the case study firms have been affected by these developments may depend on the industry segments in which they are positioned. However, it can be argued that the electric transition has blurred the lines between traditional segments of the car industry to some extent. The interview data do not provide evidence that any of the German car brands have substantially changed their positioning, but they do suggest that some of the case study companies did not have an adequate offering for the Chinese market at the time of the interviews. In addition, the study finds that China’s transition to e-mobility has led to changes in various parts of the German automakers’ value chains, including production, sales, marketing, services, research and development, and procurement. Whether these changes will ultimately result in competitive advantage, parity, or disadvantage remains to be seen.
The internal transcribed spacer 2 (ITS2) of the ribosomal gene repeat is an increasingly important phylogenetic marker whose RNA secondary structure is widely conserved across eukaryotic organisms. The ITS2 database aims to be a comprehensive resource on ITS2 sequence and secondary structure, based on direct thermodynamic as well as homology modelled RNA folds. Results: (a) A rebuild of the original ITS2 database generation scripts applied to a current NCBI dataset reveal more than 60,000 ITS2 structures. This more than doubles the contents of the original database and triples it when including partial structures. (b) The end-user interface was rewritten, extended and now features user-defined homology modelling. (c) Other possible RNA structure discovery methods (namely suboptimal and shape folding) prove helpful but are not able to replace homology modelling. (d) A use case of the ITS2 database in conjunction with other tools developed at the department gave insight into molecular phylogenetic analysis with ITS2.
This study aims at reconstructing landscape evolution in the Quebrada de Purmamarca, NW-Argentina. Thorough mapping of the existing landforms and present morphodynamic situation was conducted on the base of intensive field work and the interpretation of remote sensing imagery. Aside from geomorphological mapping, field work focused on the description of numerous sedimentological and pedological profiles. The analysis of these profiles was supported by laboratory data from field samples (granulometry, CaCO3 content) but also by a 14C age date. With particular regard to pedological questions, several samples from soil crust were micromorphologically analysed and interpreted. The resulting data allowed the reconstruction of several phases of landscape evolution in the Quebrada de Purmamarca back to the Miocene. During this phase, the Andes were still a landscape of relatively low relief being subject to processes of planation under conditions markedly more humid than today. Highly faulted and deformed fanglomerates are the first evidence of a progressing uplift coupled under an increasingly arid climate. As a consequence of continued uplift and alternating phases of erosion and aggradation, large terrace systems have formed. Particularly the youngest terrace level shows good preservation. Against the background of the intense climatic changes characteristic for the Pleistocene, these terraces have been the major focus of this study. They are built up almost entirely from coarse debris-flow sediments which are thought to be the result of a significant drop of the periglacial belt of more than 1,000 meters. This interpretation is confirmed by a variety of relict periglacial landforms like “glatthang” morphology (smooth topography), sheets of frost debris and asymmetric valleys. As sediment supply from periglacial debris production exceeded the transport capacity of the drainage system leading to the dominance of depositional processes. Aggradation has been interrupted or at least weakened several times as reflected by two lacustrine to fluvial intervals within the terrace deposits. In this context, particularly the younger interval might announce a shift in morphodynamics around 49 ka BP (14C age), when the phase of terrace aggradation grades into a phase of dominant alluvial fan activity. On the terrace surfaces a well-developed reddish soil has developed. It is interpreted to indicate a phase of increased humidity possibly in relation with the “Minchin” wet phase between 40 ka BP and 25 ka BP. At many places, this reddish soil is overlain by a markedly cemented sand crust. Based on the good sorting of medium and fine sand, this sand crust could be interpreted as fluvio-eolian sediment. Its deposition under very arid and cold climatic conditions may be attributed to the Late Glacial Maximum (LGM). However, the sand crust shows signs of erosion at many places and has not been observed anywhere below the level of the terrace surface. Therefore the onset of severe erosion and incision resulting in the evacuation of enormous quantities of sediment from the study area is assumed to postdate the LGM, possibly due to increased discharge rates during a wetter Lateglacial. Regardless of its timing, the intense incision is likely to have cut down to below the present floodplain evidently causing several mass wasting events in the study area. Since the early Holocene a number of short-term changes seem to have been responsible for the landscape evolution of the Quebrada de Purmamarca. More humid phases of pronounced slope smoothing have alternated with semi-arid phases of longer duration. The well-developed, polycyclic calcretes on top of the inactive terraces and alluvial fans give evidence for these changes. At present, the marked desert pavement on top of most terraces and alluvial fan surfaces prevent soil. The concentration of runoff on these pavements amplifies badland formation and alluvial fan activity along the terrace slopes. The presently observed floodplain aggradation may be attributed to these processes but considering the severe gullying reaching far into the upper study area, the aggradation may as well reflect a more general and regional trend.
This paper examines the relevance of tax havens for China by determining which tax havens are important for China and to what extent. Furthermore, the motives for Chinese tax haven activity are analysed and compared to the motives of Western companies that primarily use tax havens for the purpose of tax arbitrage. An analysis of two listed Chinese companies, a private and a state-owned entity (SOE), exemplifies how Chinese businesses incorporate tax havens into their business structure and discusses differences between the motives of private and state-owned companies. The magnitude of tax havens found in the business structures emphasise the importance of tax havens for Chinese companies, irrespective of whether the company is an SOE or private, or conducts its business in China or internationally. While the reasons why the state-influenced company incorporated tax havens into their structure seemed to be related to legitimate business motives, the motives behind the structure of the private company seemed questionable. The assessment furthermore confirms that China’s weak institutional framework and restricting business environment is a major push factor and gives companies plenty of incentive to go offshore.
