Towards the end of the fifth millennium BC, a new funerary tradition developed in Iberia and elsewhere in Atlantic Europe involving the use of megalithic tombs and natural or artificially constructed caves for the collective burial of the dead. Ancestor worship has been the most common theoretical framework used to explain this Neolithic burial tradition, despite demographic information which indicates that these burials house the remains of a significant percentage of children and adolescents. Using data from Late Neolithic (3500–2500 BC) tombs in south‐western Iberia as a departure point, in this paper we suggest that by reconsidering the impact that childhood mortality had upon burial and grave visitation practices in Neolithic communities, archaeologists can gain valuable phenomenological information which will allow for a more robust, multivocal interpretative approach.  相似文献

Saudi Arabia, homeland of Osama bin Laden and 15 of the 19 hijackers of September 11, 2001, experienced low levels of internal violence until 2003, when a terrorist campaign by ‘Al‐Qaeda on the Arabian Peninsula’ (QAP) shook the world's leading oil producer. Based on primary sources and extensive fieldwork in the Kingdom, this article traces the history of the Saudi jihadist movement and explains the outbreak and failure of the QAP campaign. It argues that jihadism in Saudi Arabia differs from jihadism in the Arab republics in being driven primarily by extreme pan‐Islamism and not socio‐revolutionary ideology, and that this helps to explain its peculiar trajectory. The article identifies two subcurrents of Saudi jihadism, ‘classical’ and ‘global’, and demonstrates that Al‐Qaeda's global jihadism enjoyed very little support until 1999, when a number of factors coincided to boost dramatically Al‐Qaeda recruitment. The article argues that the violence in 2003 was not the result of structural political or economic strains inside the Kingdom, but rather organizational developments within Al‐Qaeda, notably the strategic decision taken by bin Laden in early 2002 to open a new front in Saudi Arabia. The QAP campaign was made possible by the presence in 2002 of a critical mass of returnees from Afghanistan, a clever two‐track strategy by Al‐Qaeda, and systemic weaknesses in the Saudi security apparatus. The campaign failed because the militants, radicalized in Afghan camps, represented an alien element on the local Islamist scene and lacked popular support. The near‐absence of violence in the Kingdom before 2003 was due to Al‐Qaeda's weak infrastructure in the early 1990s and bin Laden's 1998 decision to suspend operations to preserve local networks. The Saudi regime is currently more stable and self‐confident—and therefore less inclined to democratic reform—than it has been in many years.  相似文献

Central to this article is the suggestion that modern planning and development frameworks in England are currently at a potentially productive, although problematic turning point. Whilst on the one hand the UK is attempting to make the legislative and institutional changes necessary to facilitate the process of regionalization and devolution, it is at the same time facing the challenge of ensuring the necessary levels of inter-agency cohesion and integration required for the delivery of the meta-objectives at the heart of sustainable development. Of particular concern for the English regions is the increasing complexity of organizational relations, the fragmentary nature of provisions, the potential mismatch between the need to preserve environmental welfare and at the same time ensure regional economic competitiveness, and more fundamentally, the failure to provide an appropriate mechanism for the evaluation of sustainable development goals. In the light of these challenges, the authors highlight the value of Strategic Environmental Assessment (SEA) as a mechanism for improving the environmental quality of decision-making and make recommendations as to how the regional level of decision-making can provide an effective platform for the development of an SEA system which is capable of reconciling the sustainability conflicts derived from different tiers of decision-making. Within this discussion, suggestions are made as to the manner in which current ideas for introducing sustainability appraisal for Regional Planning Guidance should be amended.  相似文献

This paper describes the design features and capabilities of a portable automated in‐situ closed chamber (ISCC) for the quantification of CO2 fluxes in dryland soils where both photosynthetic and respiratory components may be associated with a cyanobacterial crust. The processes of CO2 flux in dryland soils are briefly described in order to clarify the conditions that make quantification of these fluxes problematic. The instrumentation currently available for in‐situ soil CO2 flux measurements is then reviewed demonstrating their inadequacies for the dryland environment. The ISCC described here is a member of the closed or enrichment class of soil respiration chambers. The ISCC, however, features an optical window possessing high (>90%) transmission in the photosynthetic active region (PAR) of the solar irradiance spectrum, permitting observations of photosynthesis. The ISCC possesses automatic venting and purging so that gaseous concentrations inside the chamber do not change from ambient sufficiently to significantly affect diffusion. The ISCC features both active and passive cooling employing internal solid‐state Peltier coolers and external aluminised Mylar respectively. This avoids severe disturbance of the microclimate within the chamber due to admission of high fluxes of PAR and permits in‐situ operation under a wide range of ambient field temperatures (~ ?5 to 40°C). Sensors internal to the chamber monitor temperature, relative humidity, irradiance and pressure. In this implementation the ISCC is coupled to a portable gas chromatograph (Agilent GC‐3000) to sample the chamber atmosphere. Indicative data for Kalahari Sand soils of Botswana are presented as an illustration of the general performance characteristics.  相似文献

D. W. Winnicott's notion of 'transitional space' is noted as a potentially important contribution to post-Englightenment thinking because it decenters reason and logic in favor of playing with and making use of as the qualities most characteristic of human being. Winnicott is also, perhaps, the one child development theorist whose speculations parallel most closely contemporary post-modern interests of geographers. His principal concerns are how children (and adults) bridge the gap between egocentricism and recognition of an external world and how they distinguish between self and other. Unlike Piaget, Freud or Lacan, Winnicott does not problematize the separation of the child and her external environment primarily in terms of objective distancing, naming, rationalizing or compartmentalizing. Rather, Winnicott describes the place of play and child development in terms of transitional spaces which, we argue, bear close resemblance to the ideas which surround Henri Lefebvre's trial by space. In part, our intent is to spatialize Winnicott's ideas and to give specific form to some of Lefebvre's abstract notions of how space is produced. Winnicott's ideas are particularly intriguing for geographers because transitional spaces are theorized as the spaces out of and from which culture arises. As with play (an object), in culture there is something to make use of (a tradition), but the child/adult also has the capacity to bring something of her inner self to the tradition. In addition to discussing the potential of a link between the work of Lefebvre and Winnicott, the paper discusses the value to geography of post-structural feminist Jane Flax's recent interrogation of Winnicott's ideas. Flax's concern is to rework Winnicott's ideas from a feminist perspective and apply them to an account of identity formation which focuses upon justice and the play of differences. Transitional spaces help conflate notions of self and place, but they are also places wherein liberatory notions of justice and difference may develop.  相似文献
