The paper investigates the stability and change of regional economic activities in the long run. As the unit of analysis, we selected the machine tool industry in West Germany for the years 1953–2002. We spot a strong variance in the activities between different regions. These differences are relatively stable over time, and the regional activities are rather path-dependent. Nevertheless, the paper also identifies changes in the level of activities. As the main driving factors for these developments, we examine the effect of changing regional degrees of diversification over time. We find that those regions which generally broaden their scope of activities have a higher likelihood to grow than regions which are specializing. Furthermore, diversification into totally new technological and product fields is only beneficial under specific circumstances based on technological and market developments. Hence, in most cases, a broad diversification is superior to one focusing on new state-of-the-art technological fields.  相似文献

Cultural heritage management is an inherently retrospective discipline. To the detriment of future heritage management, some heritage places were not recognised and managed even though they had instant global significance after their creation (e.g. sites of the Apollo space programme). The current revolution in robotic technologies, coupled with the developments in artificial intelligence, suggests that the creation of self‐reflective robots capable of semi‐independent thought (processes) is not too far away. This paper explores the conceptual and ethical issues that heritage managers face when dealing with the heritage such robots will create.  相似文献

Abstract

Although modal split is only one of the elements considered in decision-making on new shopping malls, it remarkably often arises in the arguments of both proponents and opponents. Today, this is also the case in the debate on the planned development of three major shopping malls in Belgium. Inspired by such debates, the present study focuses on the impact of the location of shopping centres on the travel mode choice of the customers. Our hypothesis is that destination-based variables such as embeddedness in the urban fabric, accessibility and mall size influence the travel mode choice of the visitors. Based on modal split data and location characteristics of 17 existing shopping centres in Belgium, we develop a model for a more sustainable siting policy. The results show a major influence of the location of the shopping centre in relation to the urban form, and of the size of the mall. Shopping centres that are part of a dense urban fabric, measured through population density, are less car dependent. Smaller sites will attract more cyclists and pedestrians. Interestingly, our results deviate significantly from the figures that have been put forward in public debates on the shopping mall issue in Belgium.  相似文献

A system of collective bargaining at sector level emerged in Belgium after the First World War. The commissions paritaires, in which unions and employers were equally represented, became the centres of power of the pillarised Belgian trade union movement. This system of industrial relations was challenged during the general strike of 1936. Some employers tried to compete with the unions by creating factory councils, yellow unions and 'mutual societies' at company level. The strategic aim was to remove the centre of labour relations from sector to factory level. This tendency was reinforced during the Second World War. Pre-war trade unions were abolished, employers tried to take over the role of the unions by creating all kinds of social provisions at company level. The factory became a basic element of the survival strategy of the workers. Moreover, from 1941 a clandestine and more radical trade union movement, which opposed the pre-war pillarised trade unionism, emerged. These clandestine unions were organised at factory level. In their view, the factory and not the sector had to become the locus of industrial relations after the war. The organisational framework that was established between 1944 and 1952 was a synthesis of the pre-war model of industrial relations and newly established councils at company level.  相似文献

This study serves for the definition of baseline isotopic signatures of vertebrates living in the Schlei fjord, a brackish water inlet in the north German plain, where the salinity decreases from its mouth at the Baltic Sea towards the inland locations. The Viking trade centre Haithabu and its immediate successor, the town of Schleswig, are located at opposite banks of the Schlei and constitute a settlement continuum from the 9th until the 13th century. This development not only includes a relocation of the settlement site, but also a change in economy and social structure, and witnesses the metamorphosis from an international trading locality to the rise and decline of a prototypical medieval town with town charter. In this paper, stable isotope ratios of bone collagen and bone structural carbonate of 141 vertebrate bone finds mainly of fish, birds, and sea mammals from both sites are reported to provide the baseline food web in this brackish water environment, which is the prerequisite for our ongoing studies aiming at the reconstruction of human subsistence strategies as well as the geographic origin of humans, animals, food stuffs, and raw materials in order to complete the historical picture of emerging medieval towns in a complex palaeoecosystem. In particular, we are able to show how a combination of stable isotopes from bone collagen and carbonate is capable of defining the salinity gradients in the aquatic environment.  相似文献

Germany’s colonial experience in the Pacific was both relatively short (1884–1914) and also quite dispersed. In addition to administrative staff and office, a well-functioning colonial administration also required the means to propagate and document its administrative regulations and decisions. This article examines how the administrative offices in German Samoa and German New Guinea went about their official printing needs. In the Samoa case, the Germans ‘inherited’ a well-established printing environment, facilitated by newspapers. Here the official publications of the colonial government were merely additional print-jobs. In German New Guinea, however, no such infrastructure pre-existed and the German administration had to start its own press. Over time, the government gazette added no official sections and, had World War I not intervened, was on track to became a local newspaper.  相似文献

Crossed brainstem syndromes consist of ipsilateral impairment of cranial nerves III-XII and contralateral impairment of the pyramidal and sensory tracts. Gasperini's syndrome, described in 1912 by the Italian internist Ubaldo Gasperini, is one of them. It results from a lesion of the caudal pontine tegmentum and is most frequently defined as ipsilateral impairment of cranial nerves V, VI, VII, and VIII and contralateral sensory loss. Since no autopsy was performed to confirm Gasperini's clinical observations, we analyzed all elements of his syndrome from a current perspective as well as in the light of the anatomical knowledge available to him. This resulted in a historical survey of the development of neuroanatomy over the last 300 years.  相似文献
