Abstract

The subject of lobbying in the context of destinations is still a largely unstudied research field both in relation to specific destinations and from the perspective of planning. This is all the more remarkable when we consider that—despite its ambivalent public perception—successful lobbying is a crucial success factor in the positioning of destinations on a highly globalized tourism market with its rapidly changing supply and demand structures. In this article, we analyze the current lobbying structures in Bavaria, one of the leading European destinations. Bavarian tourism finds itself in an exceedingly complex situation today caught between diminishing competitiveness, especially considering the persistent investment backlog, and exceedingly ambitious tourism policies. Using semi-structured interviews we investigated how key policy-makers and representatives of the tourism business currently appraise tourism lobbying in Bavaria. From their assessments, we derive recommendations that should help to optimize lobbying structures and processes.  相似文献

This study presents test measurements on a Lexsyg luminescence reader, acquired by the Giessen luminescence group. The reader is of the type Standard, hence designed for routine determination of palaeodoses using quartz or K-feldspars. The tests include measurements of the stimulation powers, preheat temperatures, OSL- and TL-curves, as well as dose recovery tests and calibration measurements using highly sensitised calibration quartz. A comparison of D e values determined using a Lexsyg reader with single grain D e-values, which have been previously obtained on a Risø reader, is also presented. The results imply that the Lexsyg reader is a highly reliable measurement device with high reproducibility, yielding instrumental uncertainties of around 0.3%.  相似文献

Comparison is drawn between a village's circle of lay Buddhists and an association of former ex-guerrilla fighters in a Northern Vietnamese commune and their respective modes of commemoration. Both groups commemorate the same raid by French soldiers on their commune in 1948, known as the 12/01 Raid. The Association's mode of commemoration is conceptualized as legend; a story that is considered true, but which also retells the 12/01 Raid in terms of a series of ordeals and trials, and with the protagonists overcoming them. The Buddhists' commemorative mode is conceptualized as legacy to capture their vision of a common tragedy. It is argued that the Buddhists commemorate the 12/01 Raid in terms of a common, fateful point of origin, and that legend should be considered a restricted version of legacy.  相似文献

The aim of this work was to detect imprints on soil properties from former Islamic land use (9th to 11th century) using a multi-method, soil-chemical approach. Four soil profiles (with buried horizons) found in the vicinities of former Islamic settlements in Sicily were analysed for phosphorus (total, organic and inorganic), nitrogen (total, NO3 and NH4+), carbon compounds (δ13C, lipids, polycyclic aromatic hydrocarbons (PAH) and functional groups), physical and chemical C-fractions and the state of soil weathering. Two soil profiles contained ceramic sherds from the Islamic period. Inorganic nitrogen forms, phosphorous and the PAH content indicated strong impacts from traditional agriculture and/or burning. Radiocarbon dating of soil organic carbon (SOC) fractions from buried horizons showed that distinct changes must have occurred during the Islamic epoch. The isotopic composition of SOC indicated that land use was probably different in earlier times. C4 plant cultivation was expected but surprisingly lipid analyses did not confirm this. A high amount of aliphates and low C/N ratio indicated a good, long-term SOC stabilisation under the native conditions combined with Islamic land use. The irrigation of the soils probably increased the production of weakly-crystalline Fe forms that helped to stabilise SOC.  相似文献

The type (and only known) specimen of Melbournopterus crossotus Caster & Kjellesvig-Waering, an enigmatic late Silurian fossil that was initially assigned to the eurypterid family Stylonuridae, is critically examined for the first time in 60 years. It is reinterpreted as most likely the dorsal valve of a craniate brachiopod, with prominent paired adductor muscle scars (described originally as ‘lateral eyes’) situated anteromedially, a short hingeline and a spinose anterior margin.

Today pilgrimage is experiencing an increasing interest, although motives are notable changing. Sites along pilgrim routes normally profit in an economically way. But until today regional economic effects of even very small pilgrimage sites are underexplored. Therefore economic impulses of the pilgrimage site in Biberbach (Bavaria) were identified using interviews and calculations. According to that the 10,000 visitors per year generate nearly 30,000 € gross turnover and 0.5 jobs. So even small pilgrimage sites can obviously produce a notable increase of local EVA.  相似文献
