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

According to the theory of conventions, food value chains (FVCs) involve a complex array of actors who share an agreement about the qualities embodied in their particular foodstuff. Nevertheless, that agreement is continuously challenged by changes in consumer markets. Therefore, I argue that FVCs able to adapt those qualities to new trends will perform better than FVCs whose commitment to certain qualities leads to a misunderstanding between producers and consumers. The organization of the chain itself, the values of national regulatory frameworks, and the goals of the national innovation system are discussed as factors that shape an FVCs' ability to re‐arrange that core agreement. By using professional reports, statistical records and personal interviews, this article focuses on two FVCs that have experienced contrasting trajectories in recent decades in the Spanish market: the wine industry located in the region of Castile and Leon (Spain) and the Norwegian salted cod industry. The growing wine FVC has achieved a successful agreement about a set of qualities linked to nature, tradition, and place, all of them guaranteed by the reputation of the Designation of Origin (DO) system. In contrast, the salted cod FVC is losing its market share because its main actors are failing to properly communicate the key qualities of environmental sustainability and artisanal cod production to concerned Spanish consumers, as well as in the adoption of the place‐related attributes that still shape consumer preferences in Spain. 相似文献

In an article published in this journal in 2011, an alternative measure of inequality was suggested, which has subsequently become known as ‘the Palma Ratio’. In this new article, the author of the original proposal revisits the argument for such a measure. Using new data, he examines whether the current remarkable homogeneity in the income share of the middle and upper‐middle around the world — the foundation of the so‐called ‘Palma Ratio’ — is an historically stable stylized fact, or whether it is a new phenomenon, the outcome of a process of convergence towards the current ‘50/50 Rule’ (in which half of the population in each country located within deciles 5 to 9 tends to appropriate about 50 per cent of the national income, or just above). Although partly written in response to a comment on the 2011 paper (published in this issue), the article also makes a substantive further contribution to the literature on inequality and the statistics to measure it. 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
