An archaeocyathan fauna from a single limestone lens in the upper Cymbric Vale Formation at Mt. Wright shows species in common with the historic Ajax Mine fauna of the Flinders Ranges, South Australia. The Cymbric Vale fauna is considered equivalent to the lower Sanashtykgol ‘horizon’ of the Altay Sayan fold belt of Siberia. New taxa described are the genera Hyptocyathus (Inessocyathacea, Hyptocyathidae fam. nov.), Aporosocyathus (Annulocyathidae), Wrighticyathus (Sigmocyathacea, Wrighticyathidae fam. nov.), Flexicyathus (Porocoscinidae) and Bractocyathus (Polycoscinidae), and the species Erugatocyathus cymbricensis and Veronicacyathus concavus. 相似文献

Städte und Regionen unterliegen einem andauernden und
verschärften Wettbewerb um Unternehmen, Arbeitskräfte und
Infrastruktureinrichtungen. Der anhaltende technologische und
gesellschaftliche Strukturwandel—verbunden mit einer
Neubewertung von Standortfaktoren—sowie die fortschreitende
Globalisierung bleiben für die Standorte nicht ohne Folgen.
Diese Entwicklungen bedeuten für die Wirtschaftsförderung vor
Ort sowohl Risiken als auch Chancen. Chancen insbesondere, wenn
sich die Sichtweise der Unternehmen konsequent zu eigen gemacht
wird. Ausdruck dafür sind Aktivitäten, die sich hinter
Schlagworten wie Clustermarketing, private-public-partnership,
Benchmarking, Standort- und Netzwerkmanagement, Aufbau von
Kompetenzzentren und regionale Kooperationen verbergen. Risiken
sind zu vermuten, wenn Lotsenfunktionen wesentlich das Handeln
von Wirtschaftsförderung bestimmen. Werden Wirtschaftsräume als
Orte der Initiierung, Anwendung und Verbreitung von Innovationen
betrachtet, werden die Herausforderungen einer aktiven
Wirtschaftsförderung transparent. 相似文献

There is growing interest in the German‐Polish border area's future status in the changing regional structure of Europe—contrasting scenarios contain, on the one hand, a vision of the region as a new ‘tiger’ region, and are seen at the other extreme as a ‘drainage area’ on the outskirts of the EU. In this article, border areas are treated from a point of view that pays more attention to the regions’ system of production and regulation. The first part deals with some general characteristics of border areas; the second part outlines in more detail the specific developmental conditions of the German‐Polish border area, especially the region between Berlin and Poznan along the middle part of the River Oder (comprising the Euro Region Pro Europa Viadrina). Three aspects of the border region's developmental conditions are emphasized: the region's quality of location within Europe and the respective national territories; the permeability of the border; and the economic structure in the border area, whereby forms of trans‐border economic linkage and cooperation are of particular interest. The last section discusses new challenges for European border areas as posed by economic change and the restructuring of the European spatial fabric. 相似文献

We present the detailed analysis of a cervical vertebra from a cave bear, found at Pe?turina cave, Serbia, in a Mousterian archaeological level dated by radiocarbon at 43.5–44.6 kyr cal BP, and by ESR to between 93.5 and 102.5 kyr BP. Identified as a portion of the cranial articular facet, the fragment displays ten subparallel grooves. The microscopic study of these grooves and other surface modification present on the bone fragment, conducted with multifocus optical and confocal microscopes and complemented by a taphonomic analysis of the associated faunal assemblage, supports the hypothesis that the incisions were made by humans. Results are used to critically examine ambiguities implicit in the analysis and interpretation of early engravings, a category of material culture that has been playing a key role in the identification of early instances of symbolically mediated behavior. 相似文献

When a Canada‐wide daily climate time series, covering the period 1950–2010, became available, an opportunity arose to analyze the time series for trends of a variety of temperature indices. The 6,833 climate grid cells covering Alberta, each with an area of 10 km by 10 km, allowed the detailed mapping of 30 temperature indices across the province. From each time series, an annual series was computed, which then enabled trend analyses using the non‐parametric Mann‐Kendall and Sen Slope tests. New maps could be created at an unprecedented spatial resolution, and an associated website was developed to access all trends and changes between 1950 and 2010 for all grid cells at albertaclimaterecords.com . The confidence levels of some temperature trends exceed 99%, while others are below 80%. In Alberta's south, annual average temperatures have increased by 1°C to 2°C since the 1950s, but in Alberta's north the increase is 2°C to 4°C. The growing season has lengthened by between one and five weeks since the 1950s, while the number of frost days has declined. The most significant trends observed were increases in mean annual and winter temperatures, and declines in the number of days below ?20°C and heating degree days. 相似文献

ABSTRACTInnovation comprises both novelty and practicability. These two dimensions of innovation correlate partly negatively in our analysis of survey data about planning processes in declining rural districts. As argued in the literature, declining regions need innovative concepts beyond traditional counteracting strategies to ‘shrink smart’. Competitions are suggested as feasible-to-initiate innovative local concepts by the state. The German Federal Ministry of Food and Agriculture invited 39 particularly affected rural districts to participate in such a competition among the best concepts. We address the questions of how the districts dealt with the requirements for novelty and practicability in their concepts and how the rules of competitive bidding procedures influence those concepts. Answering these questions, we conducted a survey and statistically tested hypotheses deduced from governance and innovation theory. Moreover, we analysed the bidding documents. The results show that most districts came up with hardly novel and only partly practicable concepts because the organization of the competition, and local bargaining processes impede innovation. Furthermore, the ministry’s requirements for the competition overburdened local actors with a lack of resources in declining regions. As a policy implication, we propose to integrate external experts in local networks and to accompany declining regions over a longer time instead of short-term competitions and projects. 相似文献

The Black Country, a region that is only loosely defined geographically, is an area located in the West Midlands of England, which its inhabitants claim holds a distinct geographical and cultural personality. However, despite the territory's perceived uniqueness, popular imaginations of England have often overlooked the Black Country's historical and socio-cultural individuality. Therefore, given those working in a number of disciplines have recognised local football spectator communities to be significant cultural arenas, through which localism is performed and remade, this article explores the role of fandom in imagining, preserving and/or contesting notions of ‘Black Countryness’. Utilising semi-structured interviews, netnography and participant observation, as key methodological techniques, this study explores how local-spectator communities at Walsall Football Club (one of three professional football teams based in the Black Country) continually (re)negotiate a collective sense of local and regional identity. By adopting a critical approach, guided by Hall's notion of ‘cultural identity’, this research, in line with other similar studies, highlights the significant role football fandom plays in imbuing particular locales with meaning. However, more importantly, by understanding football fandom is emergent from complex, productive and interconnected cultural processes, this article is also critical of local football spectator communities and their exclusionary, as well as inclusionary, practices and customs. 相似文献
