Die Auswirkungen des Einsatzes moderner Informationsund Kommunikationstechnologien (IuK) werden oftmals unter dem Schlagwort der Globalisierung zusammengefaßt. IuK-Technologien stellen die technischen Voraussetzungen beispielsweise für die weitgehende Vernetzung von Unternehmen, für neue Formen der Arbeitsteilung und -kooperation.Im Fokus der wissenschaftlichen Diskussion um E-Commerce stehen Veränderungen auf globaler Ebene, die Frage nach den möglichen, raumwirksamen Veränderungen in den Regionen wird dagegen nur wenig diskutiert. Was aber bedeutet der Einsatz von E-Commerce konkret für Absatzmärkte, Kunden- und Lieferantenbeziehungen auf der regionalen Ebene? Besteht die Gefahr einer Schwächung insbesondere der mittelständischen, meist regional verankerten Betriebe oder bietet E-Commerce gerade für die kleineren und mittleren Unternehmen (KMU) die Chance eines Innovationsschubs? Ein Blick auf die regionale Ebene zeigt, daß hier zahlreiche Förderaktivitäten unternommen werden. Dies wirft Fragen auf: Welche Strategien sind bei dieser Förderung erkennbar? Wie geht die traditionelle Wirtschaftsförderung mit diesem für sie neuen Thema um?

In the Andes, there are several pre-Hispanic irrigation networks with structures destined for water storage. However, it has not been widely discussed in archaeological research. This is probably due to their being difficult to identify. The aim of this study is to explore the use of diatom assemblage analysis as a methodological tool suitable to help in the identification and characterization of these ancient hydraulic structures. We analyzed two archaeological structures interpreted as water reservoirs from north-western Argentina (EH1 in Antofagasta de la Sierra and U-88R1 in Yocavil) and compared them to current reservoirs. The diatom species composition and the changes in the dominant ecological groups in the studied structures highlight different periods of hydraulic behavior. EH1 contained and stored water, but there were periods of time in which there was a lack of use or abandonment of the structure. However, the U88-R1 structure does not have diatom evidence of containing standing water for a prolonged time but presence of wet soils. Thus, the structure could have been used for other water management strategies. The results show that diatom analysis is a methodological tool with a high potential to study ancestral hydrotechnologies.  相似文献

The Poema de Fernán González (or Libro del conde de Castilla) is not a crusade song, nor is it an epic poem or a historical account commemorating the foundation of San Pedro de Arlanza Monastery. It is rather a hybrid text that employs all the literary and historical resources available around the middle of the thirteenth century to an educated poet who was intent on transmitting to future generations the memory of the Count who made possible the independence of Castile. All episodes in the poem point to Castile's unique place in history, describing through the protagonist's bellicose deeds its hegemonic ascendency as the most important kingdom of the Iberian peninsula. Its destiny is determined by the hero's combative character against all enemies, whether Christians or Moors, and more specifically by confronting the powerful kings of neighboring states León and Navarre.  相似文献

In light of the increasing number of environmental problems necessitating government's attention and the limited scope and budget for addressing these issues, environmental protection has, and continues to evolve as more flexible approaches to regulation are being sought and embraced by governments throughout the world. Voluntary environmental programs (VEPs) are a pragmatic response by both governments and business to find a more flexible way to protect the environment. We discuss the theoretical motivations for firms to adopt VEPs in general and examine Canada's experience with three types of VEPs, public, negotiated, and unilateral agreements, to assess whether the motivating factors are present. We then argue that the institutional, political, and regulatory framework governing environmental policy in Canada does not provide the conditions necessary to effectively promote superior corporate environmental protection across jurisdictions. Despite the lack of government‐directed VEPs, there has been considerable interest by both the private sector and civil society who have taken the lead by developing unilateral agreements. Using existing literature and our current research, we examine the factors that motivate firms in Canada to participate in unilateral agreements and the characteristics of firms with the higher environmental performance and suggest some policy implications.  相似文献

This article examines how and in which societal and political contexts nationhood is expressed and symbolised in reunified Germany. This ‘rediscovery’ of nationhood since the 1990s mixes new and old motifs of the cultural repertoire of ‘the national’ for different purposes. Three main contexts triggered a rediscovery of ‘the national’ after 1989: reunification, immigration and the retrenchment of the social state. I argue, by analysing ethnographic material and political discourses, that these contexts, on the one hand, rearticulate old forms of ethnic and cultural nationalism and, on the other hand, create new images and symbols of an open civic society and immigration country. There are ‘playful’ forms, such as campaigns of nation branding, that symbolically include the ‘productive’ and ‘useful’ immigrant into the national project. Moreover, such campaigns serve to legitimatise the downsizing of the national state that – according to a neoliberal attitude – relies on a new community spirit of entrepreneurial, ‘activated’ citizens who ‘help themselves’. Thus, focusing on these pluralised renationalisation processes makes evident how polyvalent ‘the national’ still is. It can be employed by those who attempt to ‘reunite’ the East and West Germans, by businesses to sell their goods and ideas and by almost any political orientation, be it right‐wing or left‐wing.  相似文献
