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?

The Maisin women of northeastern Papua New Guinea are among the last coastal Papuans to tattoo their faces. This article first describes the techniques and social process of Maisin tattooing. We then examine the resilience of the custom in light of changes in puberty rites and notions of gender. We argue that these contexts have lost their cultural salience as a result of the Maisins' incorporation into the larger Papua New Guinea society. Tattooing has acquired new significance as a marker of cultural identity in a multicultural setting and as a sign of the Maisin people's commercial success as makers of indigenous art. 相似文献

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

As technologies grow in complexity, firms often target their internal R&D resources on core competencies and utilize outside sources for supporting knowledge and technology. Where do firms turn to find such resources? This paper reports the perceptions of technology transfer managers in United States manufacturing firms toward federal and university labs and identifies the types of farms that are better positioned to utilize externally available technological resources. Based on replies from research-intensive companies within the United States, the authors find that larger firms with high research and development (R&D) budgets tend to ascribe greater significance to external sources than do smaller ones. Also, companies spending over $500 million in R&D rank universities the most significant external source of knowledge, followed by V S.-based firms, and then foreign firms. 相似文献

A pair of mandibular rami from a brown bear (Ursus arctosL.) was found at the rock shelter of the Grande-Rivoire in the Castelnovian level. Both exhibit a peculiar deformation affecting the bone between the first and second molars and the roots of these teeth.The perfect symmetry of this deformation, the absence of pathological features, and the misplacement of the teeth suggest that a thong had been placed around the mandible while the animal was young; the mandible then grew around the thong.The interest of this find is that it both demonstrates the taming of a bear and the complexity of the relationships between humans and animals during the late Mesolithic. 相似文献
