ABSTRACT

This paper will examine settlement location during the Iron Age in the northeast part of the Netherlands, an area shaped by Pleistocene geology. In recent years, a number of Late Iron Age/Early Roman settlements situated on the low lying slopes of sand ridges and nearby stream ridges revealed traces of an earlier Iron Age occupation. Palynological data revealed that this part of the landscape was used by humans before it was transformed into an area of settlement. An analysis of excavation data from two key sites at Denekamp-De Borchert and Groningen-Helpermaar, as well as other known sites, lead to the conclusion that the transformation of ‘peripheral landscapes’ into permanent settlement locations was preceded by a phase of arable cultivation which left no trace of permanent habitation. It is also suggested that the impact of human behaviour on the natural landscape in the Early and Middle Iron Age was much bigger than previously anticipated. When excavating this type of settlement areas dating to the Late Iron Age, archaeologists must be aware that only of a small group of archaeological features exist. The proposed model for the choice of settlement location may be more widespread, because of similarities in landscape between the study area presented here and other landscapes in Northwest-Europe (e.g. parts of Germany and Denmark).  相似文献

The area of La Caleta, north‐west of Cadiz, is a key location for studies of the relationship between the Phoenician city of Gadir and the ocean. The port channel and the small islets that characterize the area was one the busiest sectors of the city, and there are abundant underwater remains attesting to past commercial activities. The area also had an important religious role: two sanctuaries were located at the western end of the rocky promontories that surround the channel, and many items identified as offerings have been found. This article synthesizes previous research and provides an overview of the results of a recent project (2008–2010), which enables a thorough review of the development of the seascape and its use during the 1st millennium BC.  相似文献

A lack of clear political commitment together with confusing rules and enforcement often characterize the institutional context of policy implementation and regulatory compliance in developing countries. By connecting such contextual features to existing models of policy implementation and regulatory compliance, we examine how regulatory factors are related to basic and proactive corporate environmental management practices in the Pearl River Delta region in China. Drawing on data derived from both a survey and in‐depth interviews, we show that a perception of clear political commitment to environmental protection across multiple government levels and units is positively associated with business efforts in basic environmental practices, regardless of the specific enforcement intensity. Nevertheless, a perception of clear political commitment is not related to proactive environmental practices. Conversely, a perception of policy ambiguity, in the form of confusing regulatory standards and enforcement, is negatively associated with corporate efforts in both basic and proactive environmental practices; yet, intensive inspections mitigate these negative associations with policy ambiguity.  相似文献

This paper proposes a new definition of the term ‘subculture’, as a way of better understanding hybrid identities specific to East‐Central Europe, before applying this definition to a case study from the now‐Ukrainian city of L'viv from around 1900. The first section outlines the theory, arguing that the continued focus on the nation state – either from the ‘top down’, or else the ‘bottom up’ as a source of contestation, by historians and anthropologists, has limited the ability to study groups in the interstices of the national projects that typically remain defined in monolithic ethno‐linguistic terms. It examines the theoretical term ‘subcultures’ to propose a new definition that accounts for such hybridity, by having particular sensitivity to context (historical, social, geographical) and cultural practice, in addition to any prevailing national narratives at a given time. The case study in the second section focuses on linguistic hybridity in the city then known more commonly as Lemberg (German) or Lwów (Polish). It argues that Lemberg/Lwów/L'viv produced an urban dialect that blended Polish, Ukrainian, Yiddish and German elements. This dialect should be reassessed as a mixed, hybrid or transitional code, rather than as a linguistic variant of a titular nation. Archival evidence – in particular, court records – is quoted to show that at the lower end of L'viv society, people routinely mixed and transcended linguistic and, thereby, ethnic and religious boundaries. This offers direct evidence of a specific subsection, or subculture, in urban life where people interacted and intermingled intensely. As such, the paper offers new possibilities for investigating ‘hybrid’ identities, as well as proposing a counterpoint to recent research focusing on deliberate indifference or opposition to national segregation for various socio‐political, economic and cultural reasons (Judson 2006: 19–65; King 2002; Zahra 2008).  相似文献

Accurate simulation of multiphase flow in fractured porous media remains a challenge. An important problem is the representation of the discontinuous or near discontinuous behaviour of saturation in real geological formations. In the classical continuum approach, a refined mesh is required at the interface between fracture and porous media to capture the steep gradients in saturation and saturation‐dependent transport properties. This dramatically increases the computational load when large numbers of fractures are present in the numerical model. A discontinuous finite element method is reported here to model flow in fractured porous media. The governing multiphase porous media flow equations are solved in the adaptive mesh computational fluid dynamics code IC‐FERST on unstructured meshes. The method is based on a mixed control volume – discontinuous finite element formulation. This is combined with the PN+1DG‐PNDG element pair, which has discontinuous (order N+1) representation for velocity and discontinuous (order N) representation for pressure. A number of test cases are used to evaluate the method's ability to model fracture flow. The first is used to verify the performance of the element pair on structured and unstructured meshes of different resolution. Multiphase flow is then modelled in a range of idealised and simple fracture patterns. Solutions with sharp saturation fronts and computational economy in terms of mesh size are illustrated.  相似文献

This paper investigates how small entrepreneurial firms in two peripheral regions developed by entering the oil and gas industry. The paper draws on previous studies related to the establishment of strategic alliances and emerging clusters and contributes to these research streams by examining the disadvantages of peripheral localization and small firm size. We use a longitudinal case study based on primary data consisting of 54 in-depth interviews conducted between 2007 and 2012 to illustrate that when large-scale oil and gas projects enter a peripheral region, oil companies can moderate local firms' disadvantages related to peripheral localization by actively facilitating relationships with established national firms. By facilitating such relationships and maintaining an active moderating role, strategic alliances and emerging cluster structures can arise. A cross-case analysis illustrates that the oil company had a decisive role in one of the two cases in two dimensions: its role as intermediary between local firms and national firms and its role in fostering the development of an emerging cluster structure by stimulating the establishment of new firms through the oil and gas project. In the second case, the oil company was unable to facilitate regional development.  相似文献

This article introduces latent trajectory models (LTMs), an approach often employed in social sciences to handle longitudinal data, to the arena of GIScience, particularly space‐time analysis. Using the space‐time data collected at county level for the whole United States through webpage search on the keyword “climate change,” we show that LTMs, when combined with eigenvector filtering of spatial dependence in data, are very useful in unveiling temporal trends hidden in such data: the webpage‐data derived popularity measure for climate change has been increasing from December 2011 to March 2013, but the increase rate has been slowing down. In addition, LTMs help reveal potential mechanisms behind observed space‐time trajectories through linking the webpage‐data derived popularity measure about climate change to a set of socio‐demographic covariates. Our analysis shows that controlling for population density, greater drought exposure, higher percent of people who are 16 years old or above, and higher household income are positively predictive of the trajectory slopes. Higher percentages of Republicans and number of hot days in summer are negatively related to the trajectory slopes. Implications of these results are examined, concluding with consideration of the potential utility of LTMs in space‐time analysis and more generally in GIScience.  相似文献
