The antiquity and context (site or feature type) are the two principal factors that act as a framework for interpreting charcoal and wood data from archaeological sites in the recreation of past woodland environments. This research addresses these parameters through the analysis of over 18,000 charcoal fragments from 57 archaeological excavations carried out along a 61?km road scheme in the midland region of Ireland. Observations on spatial vegetation dynamics and woodland resource patterns are also reported on. The data were analysed through percentage frequency and multivariate analyses. The results reveal woodland resource usage in terms of wood types selected for use as fuel or as structural wood as well as patterns of change and variability in taxonomic composition in relation to site types, feature types and time periods. Selection was found to be low in prehistoric times and in particular at burnt mound sites/fulachta fiadh but became increasingly important as time progressed. This has important implications when charcoal from archaeological settings is used in environmental reconstructions.  相似文献

A robust debate among coastal geomorphologists as to the processes by which beach‐ridge plains around Australia have formed was initiated by a former President of the Institute of Australian Geographers. This review gives special consideration to the work of Jack L. Davies, whose academic contributions to coastal geomorphology in Australia have not always been appropriately acknowledged when explaining how similar plains have evolved elsewhere in the world. Davies recognised that relatively steep storm waves caused erosion (cut) on beaches, whereas less steep long‐period swell waves returned sand (fill). He considered the beach berm to be the nucleus on which a beach ridge formed, which could subsequently develop into a foredune, in contrast to cobble ridges that were deposited during storms. Offshore conditions regulate supply of sand to the shoreline, partly through effects on wave refraction, with higher rates of supply where the nearshore is shallow. It was apparent to Davies that the elevation of successive ridges might, but not necessarily, provide evidence of past changes of sea level, despite adornment by variable amounts of windblown dune sand. Morphodynamic understanding of long‐term coastal evolution, based on radiocarbon dating chronologies, has demonstrated that Australian coastal plains formed over the past ~6,000 years when sea level has been close to its present level, in contrast to several documented locations in the northern hemisphere where the sea has been rising for the past few millennia. Particularly insightful were observations by Davies that ridge formation could be influenced by a range of factors including changes in sea level, storminess, or sediment supply. These factors acting singly or in combination seem likely to change in the future. Understanding such responses remains a high priority and can be addressed by new technologies, such as light detection and ranging, optically stimulated luminescence dating, ground‐penetrating radar, and computer simulation.  相似文献

River basins are an extremely important source of freshwater for Africa and the impact of climate change on these communities constitutes an important question worth studying. Among these basins, the Niger River Basin is an ideal candidate for meso-level theory testing of climate change-induced political violence because of its importance as one of the largest sources of freshwater in Africa, its high vulnerability to climate change, and its location in a politically unstable region. This paper utilizes the benefits of GIS to test whether effects of water insecurity on the various incidences of political violence are conditional on economic, geographic, and social means of connectivity. Our analysis uses the density of secondary road networks, the geographic distance to the Niger River, and a shared co-ethnicity with one's head-of-state to evaluate the impact of hydrological stress and its subsequent risk for political violence across nine West African countries from 1997 to 2012. Using climatological data and an econometric de-trending method, we measure the separate, substantive impact that individualized changes in precipitation trend and precipitation variability have for the incidence of ACLED's political violence events, conditional on local economic, geographic, and social factors. Our results reveal a complicated web of circumstances under which certain forms of political violence are more/less likely to be observed. The implications of this analysis serve as a call for a closer inspection of the micro-channels by which climate stress impacts heterogeneous communities in the developing world.  相似文献

ABSTRACT

Recent scholarly work has enhanced our understanding of how new path development activities are enabled or constrained by ‘regional environments’, made up of pre-existing industrial structures, knowledge organizations, support structures and institutional configurations. This paper moves beyond overly static views on regional environments. We develop a dynamic perspective by analysing conceptually and empirically how a constraining environment can be transformed into one that enables the development of new growth paths. The paper offers a typology of various modes of change, including layering, adaptation and novel application that are used by key actors to ‘manipulate’ the regional support structures to facilitate new regional industrial path development. The conceptual framework is applied to a case study of the digital games industry in the region of Scania, southern Sweden. Our findings suggest that the creation of a more enabling environment for the growth of the digital games industry has been the outcome of multi-scalar processes and combinations of various modes of change employed by a few key individuals operating in the newly emerging path.  相似文献

Abstract

This essay offers a critical analysis of the ‘culture and sustainable development’ discourse, notably among cultural activists and in actually existing cultural policy. It interrogates the utility of the narrative, seeks to uncover the semantic manoeuvres it employs and challenges the conventional wisdom it represents. The essay first explores the itinerary of the ductile notion of ‘sustainability’, the ways in which it has been stretched far beyond the original intent of those who coined the term, and identifies the conceptual discontents that this semantic multiplication has entailed. It hypothesizes that precisely because the term ‘sustainable’ and its derivatives are so acceptable and malleable at the same time, they have been easy to yoke to the bandwagon of the many-faceted and totalizing process that is ‘development’, allowing many different actors to project their interests, hopes, and aspirations under this composite banner. The essay then analyses the campaign to make culture ‘the fourth pillar of sustainability’ under the banner of the movement called ‘Agenda 21 for Culture’. It concludes with a plea for a return to the original ecological focus of the term ‘sustainability’ – notably as regards climate change – and outlines some cultural policy responses such a focus can and should generate.  相似文献

The People’s Party toppled the Siamese absolute monarchy and introduced constitutional democracy in Thailand in June 1932. Scholars have generally denied that the revolution had any popular resonance, but this article shows that in Buddhism, the country’s premier cultural form, democratic rhetoric in the 1930s resonated among young monks marginalised by the ecclesiastical hierarchy. A group of young monks within the Mahanikai, or Great Order, rebelled against the palace-established Thammayut order that exercised the most power in institutional Buddhism. A “thin” or formal democracy established in 1932 – one displaying the main trappings of a regime of popular sovereignty but purposefully limited in scope by the People’s Party – thus inspired an assertion of a “thick” democracy, or democracy as a much older social value that governed both the Sangha internally and its relations with local communities, which the Mahanikai activists claimed was the core of original Buddhism.

The debate on the financial crisis is at an impasse. Neoliberal austerity discourse is often positioned as an almost insurmountable barrier, its disciplinary power affecting even the most change‐oriented citizen‐initiatives existing today. Countering this, this paper highlights the transformative capacity of social movements in Thessaloniki. Drawing from Butler, Laclau and Mouffe, and Gibson‐Graham we develop the notion of “communal performativity” both as an academic and as a practical concept to understand and build trajectories of socio‐economic change. “Communal” denotes the drive of the movements’ participants to interconnect and (re)negotiate with a multiplicity of Others, curbing identity politics to articulate internal differences and Otherness. We see some hopeful signs of bridges being built towards shared trajectories of change that can be understood as different but concrete variations on the abstract counter‐narrative of “breaking with neoliberalism”. Some of these variations challenge, others diversify neoliberal discourses and practices.  相似文献

The environmental movement in the global North is in a state of impasse. It appears that despite the renewed international focus on climate change, and the actions of innumerable social movements, a “solution” to the problem appears as one, without a viable solution. It is the contention of this paper that climate change has no clearly viable solution as it is a seemingly impossible problem. This paper investigates how the problem of climate change is constructed as a global object of political action and how it functions to render politics into a matter of calculative action, one that seeks—but fails—to take hold of a slippery carbon infrastructure. It concludes by suggesting one possible solution to this dilemma is to turn away from the global scalar logic of climate change and towards a situated focus on questions of infrastructure, or what Dimitris Papadopoulos calls “thick justice”.  相似文献

The Tequila Valleys, in Jalisco, Mexico, are well-known in archaeology for an early complex society known as the Teuchitlán tradition (350 b.c.a.d. 450/500), but later developments have received little attention. Here I report on the first systematic, full-coverage survey of the Tequila region north of the Tequila volcano. I explore the ways in which the societies that occupied this territory experienced sociopolitical change diachronically by investigating settlement scale, integration, complexity, and boundedness. Through the use of these core features, I analyze how each changed in varying ways, resulting in patterns that do not conform to static societal categories. Interestingly, there is no evidence that a large polity controlled the entire region at any point in the sequence. Results indicate a dynamic sociopolitical landscape that did not develop along any predetermined pathway.  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
