Daily growth increments in fish otoliths have been demonstrated for the first time on Quaternary sagittae from a late palaeolithic site in Egypt and they have allowed us to establish the season of fishing. Transverse sections of tilapia sagittae studied under light-microscope demonstrate that recrystallization during diagenesis renders the majority of the margins unreadable. The well-preserved otoliths, however, all have widely spaced outer growth lines, indicating that the fish died during a period of fast growth which coincides with the flood season. Moreover, counting the daily increments showed that late palaeolithic man captured the animals on the floodplain of the Nile after the maximum of the flood, when residual pools were present. 相似文献

This article explores the life histories of two Namibians who grew up in SWAPO's exile camps in Angola and their ‘futuring’ trajectories once they returned home to Namibia after independence. Presenting these actors’ life histories of navigating Namibian society helps challenge a one-sided economic interpretation of precariousness. More critical than asserting dichotomies between ‘elite’ and ‘precariat’ are the stratagems and choices shaping lived experiences. 相似文献

Reality versus Policy: The Delineation and Testing of Local Labour Market and Spatial Policy Areas 总被引:1,自引:0,他引:1
As part of the empirical planning science, this article integrates theory, empirical findings and policy. It first deals with the question how to reach a theoretically well-grounded and empirical applicable delineation of local labour market areas. An inductive classification method is selected based on the behaviour of individual commuters without selecting a priori central places. By this, new urban forms like polynodality are included. In using this method for the Netherlands, 31 local labour market areas (LLAs) were distinguished. Moreover, the article elaborates some simple measures to test the optimality of LLA classifications. The 31 LLAs adequately reflect the 'reality' of actual functional labour market relationships. The article also investigates the matching between reality and the LLA classification as used in spatial policy. There is a large gap between reality and policy. This urges bringing the policy classification more in line with existing LLAs. Alternatively, if one considers the present policy classification as an instrument for future spatial structure, much additional effort will be required. The findings of the article can be easily applied to other European countries. 相似文献

The saturation magnetization σ of soft baked pottery appears to be determined during the firing process by transitions between the iron oxides magnetite, maghemite, hematite and perhaps goethite. The finding of large variations in σ motivated the design and construction of a ‘magnetization–gravitation’, or ‘MG’, balance for rapid non‐destructive magnetization measurements. The first results with this MG balance are presented: iso‐σ contours, typical histograms and correlations with colour features. Practical MG applications are summarized. 相似文献

This article uses letters by indigenous converts to explore how early modern Moravian missions in the Atlantic imagined themselves as emotional communities. Moravian missions were the most successful Protestant mission enterprise in the Atlantic and established numerous missions across several empires and vastly different indigenous cultures. By comparing the letters from indigenous converts across the Atlantic rim (North America, Caribbean and Greenland) I argue that indigenous people used the medium of the written letter to participate in an imagined emotional community of Moravians while at the same time they negotiated inescapable social and gendered differences in very specific colonial contexts. 相似文献

In this paper, we reflect on the role of concepts in spatial planning as reproductive devices of discursive configurations. In contrast to instrumentalist interpretations of spatial concepts, we start from the idea that spatial planning concepts are inherently political. Building on post-structuralist strands of thought, we discuss the theoretical concepts of “empty signifier” and “master signifier” and instead, after analysis, put forward “open concepts”, in order to grasp the richness of meanings and functions of seemingly vague concepts. This manoeuvre allows us to analyse the trajectory and performance of the spatial concept of the “innovation campus” in the Netherlands. This, in turn, opens the door to an analysis of planning concepts as crystallization points and enablers of discursive configurations. The Dutch innovation campus is shown to be a result of a confluence of various national and international discourses, an open concept, flexible enough to enable the continuation of the planning game within the familiar set of coordinates. Because of the particular set of expectations associated with the innovation campus, promising structural change, it is bound to produce disappointment. 相似文献

Transport corridors are viewed as a promising way forward in European Union (EU) transport policy, assumed to contribute positively to regional economic development. However, the validity of this assumption is not evident. The aim of this paper is to empirically test whether agglomeration economies in European transport corridor regions are positively related to indicators of regional economic development compared to regions outside the scope of corridors. The results build on the notion that the type of agglomeration economy in combination with the structure of the economy matters for prospects of structural economic growth in different regions. In this way, the analysis not only contributes to enhancing the empirical scrutiny of the corridor concept in EU transport policy, but also provides new insights into how corridors contribute to regional economic growth. We find only limited evidence for a corridor effect across European regions on productivity and employment growth externalities. Instead, we find a large degree of spatial heterogeneity interacting with corridors—a heterogeneity that has been little recognized in EU policies. We suggest that recent attention to place-based development strategies may accord well with the kinds of agglomeration effects related to corridor development observed in this study. 相似文献
