This article presents a method to identify “Absolute and Relative Employment Concentration (AREC) areas” for a particular industry. Two novel characteristics of the method are that it simultaneously analyses AREC, and that it combines spatial concentration per area with the spatial concentration in neighbouring areas. The method is easy to understand and apply. It is developed to assist regional policy makers and corporate decision-makers with their investment decisions related to new infrastructure or plants. The identification of concentration areas also allows for analysing the performance of these areas in relation to characteristics such as infrastructure availability and the housing and labour market. This can yield new academic insights that are relevant for regional planners. An application of the newly developed method to five industries in a Dutch province subdivided into 502 areas illustrates the value of the method in comparison to other methods. 相似文献

Primary sources from the end of the Bronze Age have long been read as suggesting a time of chaotic transition, particularly with regard to threats from the sea that the established powers had no means of combatting. While the scale and severity of seaborne attacks seems to have increased in the late 13th century, these were not in themselves new phenomena, as a state of maritime threat seems to have been a constant for coastal polities and mariners in the Late Bronze Age eastern Mediterranean. However, a combination of internal and external factors in the late 13th and early 12th centuries combined to make these attacks more effective than they had been in the past, and polities more vulnerable to them. These included the rapid spread of improvements in maritime technology, particularly from the Aegean and the Levant, via high–intensity ‘zones of transference’, as well as an increase in the scale of ship–based combat operations, due in part to the displacement of people during the Late Bronze Age collapse. This paper addresses this in two parts, beginning with the ‘background’ evidence for a constant state of maritime threat in the centuries leading up to the end of the Bronze Age, and concluding with the ‘foreground’ evidence for zones of transference and the transmission of groundbreaking elements of naval technology in the years surrounding the Late Bronze–Early Iron Age transition. 相似文献

Urban excavations often uncover complex stratigraphy that is difficult to interpret by archaeological experience alone. Versions of Single Context Recording can be useful tools, but this method is known to be demanding when co‐employed by consulting geologists in the field. Are these difficulties caused by fundamental differences between the views of archaeologists and geologists, or are they mainly a result of lack of mutual understanding? What would happen to field methods and interpretations if a geologist worked alongside an archaeologist at an urban excavation throughout a whole excavation season? This approach was tested at a geoarchaeological excavation in the town of Norrköping, Sweden. The experiment led to the development of a new field procedure involving continuous pilot sampling and on‐site analysis of plant macrofossils. It provided new ways of using natural sediments and redeposited layers in the interpretation of the sites development and clearly confirmed that mutual understanding is the key to interdisciplinary cooperation. 相似文献

The literary image in Sappho 1.7–15 of a goddess ascending on and travelling by a chariot which is yoked to birds occurs also of the Daughter of the Sun in hymn 1.118 of the Rigveda. Apart from the image as such, the shared context of prayer in the two poems and certain features common to the identities of both goddesses suggest that the images share a common ancestor in Indo-European religious discourse. In Sappho 1.18, the emendation πε?θην, together with the understanding of the major ms. tradition in v. 19 as a crasis κ?c?γην?相似文献

Abstract The authors study the 30 insurgencies occurring between 1978 and 2008 using four methods crossing the qualitative/quantitative divide. The four approaches are narrative, bivariate comparison, comparative qualitative analysis, and K-medoids clustering. The quantification of qualitative data allows the authors to compare more cases than they could “hold in their heads” under a traditional small-n qualitative approach, improving the quality of the overall narrative and helping to ensure that the quantitative analyses respected the nuance of the detailed case histories. Structured data-mining reduces the dimensionality of possible explanatory factors relative to the available observations to expose patterns in the data in ways more common in large-n studies. The four analytic approaches produced similar and mutually supporting findings, leading to robust conclusions. 相似文献

The main purpose of the article is to try to show how British governing elites constructed their world through a complex mental grid summed up in the word ‘character’ and how this impacted upon imperial governance. The latter theme is then illustrated through a detailed study of the financial policies of the small cadre of British officials who controlled Egyptian government in this period. They used the language of character to justify being in Egypt in the first place and it clearly influenced the financial policies they adopted. More fundamentally, as we shall see, the character grid gave them a very negative view of Egyptians and their society and made it impossible for them to recognise that nationalist claims for autonomy had any validity. 相似文献

The Himalayas are among the world's youngest mountain ranges. In addition to the geologic processes of mountain building and erosion, they are also highly vulnerable to human influenced change, occurring at local, national, regional, and international scales. A photo-elicitation methodology is employed to show how residents perceive those changes from historical perspectives, as well as their current conditions and impacts on their daily lives. Nepal's Khumbu region has undergone major social and environmental transformations since the 1960s when international trekking first began to influence the area's economy. The current perceptions of Khumbu residents of these changes are assessed through photo-elicitation interviews. Their responses are placed in the historical context of: (1) institutional and political changes, most of which have been driven by national government policies; (2) social and economic changes, for which the tourism economy has been central; and (3) environmental changes, reflecting the impacts of resource management and climate change. The mostly positive perceptions of Khumbu residents toward how their region has changed reflects general improvements in the physical and cultural landscapes of the Khumbu over time, as well as its continuing geographic isolation, which has helped to slow the rate of globalization, while also keeping the region a dynamic and popular tourist destination. 相似文献
