The paper explores processes of transnational network building in Europe in the 19th and 20th centuries. The first section reviews several relevant literatures. It concludes that historiographies of Europe often recognize the pivotal importance of transnational network building, but fail to analyse network developments as well as their entanglement with wider historical processes. Specialized infrastructure studies exist in economic and technological history, but have a distinct (sub)national focus. The networking of Europe has not been investigated. The second section presents a preliminary narrative of transnational network building in the 19th and 20th century. It highlights the relationship between network building and political events in different eras, as well as different types of ambiguities or tensions. The conclusion suggests a number of topics for further research. 相似文献

Jens Christensen 《SJOT: Scandinavian Journal of the Old Testament》2013,27(2):315-317
The enigma in Psedo-Philo Chapter 19: Istic mel, apex magnus, momenti plenitudo, et ciati guttum, is often emended by the commentators. We take it as it stands. As the surrounding texts reflects, Deut 34 and Pseudo-Philo always shows a deep understanding of the biblical text, we find that the often quoted utterings in Deut: ''a land flowing with milk and honey'' and: ''the place which the Lord your God will choose'' make sense for the first two parts of the enigma. The third part points to the coming great achievements: The death of Moses and the immigration to the Holy Land. Only the fourth part is pointing to the end of time. 相似文献

Economic measurement tools allow a quantification of social differences not only for modern societies, but also for prehistoric communities. The use of Gini indices and Lorenz curves for the much discussed Chalcolithic cemetery of Durankulak (Bulgaria) indicates an average increase in material items from 5000 cal BC onwards and a tendency of these items to be distributed somewhat more equally. Towards the end of the Chalcolithic sequence, however, strongly growing inequality was associated with lower average welfare. The steep increase in social inequality might be one of the main reasons for the collapse of Chalcolithic societies around 4100 cal BC in Durankulak, but also in other South East European regions. 相似文献

New Approaches to Innovation Policy: Some Norwegian Examples 总被引:1,自引:0,他引:1
The paper describes and assesses three Norwegian innovation policy tools. The tools cover three different models of strengthening firms' innovation capability, i.e. direct financial support, broker and advisory systems and technology or knowledge centres. The tools include some new elements in innovation policy design, and thus, some elements of good practice. Guidelines for good practice includes an interactive perspective on innovation support, a focus on innovation systems, context sensitivity and a regional focus, learning in the support system and receiver-oriented and proactive working methods. 相似文献

What is disclosed in the questioning of the human being in post‐humanism? Addressing this question in congruence with Heidegger's questioning of being in Being and Time, we end up with two discoveries: first, that the characteristic of Dasein, as the being of the questioning, already carries the same implications as the post‐human figure, and second, that questioning in this sense is indicative of the effort of realizing anew scientific space for conceptualizing the human being as non‐substantialist. Conceived of in this way, however, post‐humanism is a result of a very human effort indeed. 相似文献

Phenol Formaldehyde Revisited—Novolac Resins for the Treatment of Degraded Archaeological Wood

Archaeological wood is usually severely degraded. The Norwegian Viking Age Oseberg find exemplifies problems arising due to past conservation treatments and the need for new types of preservatives. Phenol formaldehyde (PF) has been investigated as a consolidant for alum‐treated wood. X‐ray tomography has revealed that it is possible to obtain a porous structure inside the wood, ensuring ethical acceptability by allowing re‐treatment. In order to understand the curing mechanics, the kinetics of the initial condensation reaction were elucidated at room temperature. It was found that a second‐order reaction using both phenol and formaldehyde concentrations is the most probable mechanism. 相似文献
