A problem which has arisen in discussions of an elm-disease explanation for the Neolithic elm decline has been the lack of fossil records of Scolytus scolytus (F.) (elm bark beetle), which is the main carrier of the fungus which causes the present epidemic of Dutch Elm Disease. Now, the discovery of wing cases of two individuals from elm decline deposits at Hampstead Heath, London, proves that the beetle was present in Britain during this episode. The deposits in which it occurs are described, and the various implications for elm disease causing, aiding or at least occurring during this stage of the early Neolithic are discussed. 相似文献

This paper explores the career of Ruth Taylor White, an American cartographic illustrator who published a significant number of pictorial maps from the 1920s into the 1940s. Taylor White’s ‘cartographs’ (as she called them) were characterized by her signature bobble-headed cartoon characters who romped through colourful, attractive landscapes. These visually rich and highly narrative maps simultaneously strove for accuracy and engaged in profound stereotyping with regard to culture, race, gender and class. They reveal not only the aesthetic and conceptual preferences of their maker but also the cultural biases of their middle-class, white American audience. 相似文献

Isolation effects on the distributions of plant species in fragmented forests appear to be weak over tens to hundreds of years and strong over geological eras. The 250 km wide, 6.5 millennia old Bass Strait, and other millennium-scale disjunctions in the range of Eucalyptus regnans forests, were used to determine the effects of intermediate periods of isolation on plant species occurrence and composition. Three of six floristic communities were found on both sides of Bass Strait. The residuals from multiple regression models using climatic variables on the latitude vector were not explained by latitude, indicating negligible isolation effects from Bass Strait. However, there was a lesser compositional effect of disjunctions within land masses than between land masses, suggesting some effect of the larger barrier. No species that commonly occurred with E. regnans and were largely confined to wet forest exhibited absences from any region where the climate and soils were within their range. If areas isolated from each other for millennia can maintain their vascular plant biota, the expenditure of conservation funds on creating corridors to connect large areas separated by anthropogenic landscape modification might require more justification than it is currently afforded. 相似文献

在乡村振兴背景下,旅游生计成为乡村可持续发展的重要议题,但与之相关的研究较为匮乏。文章以栾川县重渡村为案例地,通过对亲代和子代进行半结构化访谈,探讨旅游生计代际传承的过程及其主要影响因素。研究发现:(1)旅游生计的代际传承经历了亲代生计开拓、子代培养和发展、共同经营、生计传承四个阶段,并与重渡村这一乡村旅游目的地起步、培育、快速发展、规范管理的生命周期相适应。(2)文化因素、主体因素和规制压力是影响生计传承的主要原因。(3)旅游生计的代际传承关乎乡村旅游的可持续发展和乡村振兴战略的有效实施,相关问题值得进一步探索和研究。 相似文献

We have investigated the environmental history of human occupation and the development of agriculture in the eastern interior Lake District of Finland. The material consists of archaeological data, which is reviewed in topographical and agrogeological context, and pollen analytical evidence of agricultural indices from eight precisely dated (varved) lake sediment sequences. Before the Viking Age, archaeological evidence, consisting of stray finds, dwelling sites, and graves, is very scarce. Iron Age finds are clearly confined to the lowland environs with silty and clayey soils. During the Viking Age, the number of stray finds multiplies and the first cemeteries are established. Comparison between Viking and Crusade Period finds reveals a topographic shift toward higher locations and morainic soils. Most of the cup-stones are located on upland sites—that is, not in connection with known Iron Age sites. These are interpreted as medieval indicators of slash-and-burn farming of the fertile but stony supraaquatic morainic soils. There is pollen analytical evidence of sporadic cultivation in the area from the Bronze Age onward. Afterca. AD 700, the occurrence of cereal pollen grains becomes regular but remains discontinuous at each site until after the turn of the millennium. There is then an exponential rise in the cereal pollen rain, indicating a fully agricultural population. 相似文献

Practices of outdoor illumination have dramatically changed in the last decades as functional lighting has progressively given way to a more qualitative vision of light. Its traditional role for security purposes has been progressively matched by the use of illumination for city beautification. This is now a major consideration for new lighting strategies. As a result, a growing number of European cities explicitly include the development of nocturnal tourism among the objectives of their lighting policies. However, little attention has been paid by academic research to this growing trend. Focusing on the internationally renowned lighting project ‘Ruta de los Rios de Luz’, this research paper explores the use of lighting design for tourism purposes. Through interviews with individuals who played an important role in the project, the discussion below scrutinizes the lighting design decisions and the economic, environmental and political objectives that inspire the growing utilization of spectacular forms of illumination for tourism purposes. 相似文献

AbstractEcofeminists maintain that seemingly diverse and naturalized socio-ecological issues are in fact rooted within a particular cultural framework that perpetuates inequality and severs relationships among human and more-than-human communities. This important yet perhaps abstract understanding can be made tangible via examination of the ‘conventional’ food system, in which human and more-than-human communities are simultaneously otherized, marginalized, and exploited, realities largely hidden in a global industrial food system that disconnects production from consumption and obscures embedded relationships. Yet as consumer awareness rises, more people wish to know and move closer to the sources of their food, fueling community-based agro-food alternatives. When endowed with an ethic of care, such alternatives can be transformative for individuals and communities across scales.This article situates conventional and alternative agro-food systems within relational frameworks of ecofeminism and care ethics and uses participant-driven photo elicitation (PDPE) to engage with experiences of consumers participating in a community farm tour. Findings suggest that such ‘enchanting’ experiences can begin to (re)embed food ‘products’ within contexts of place, people, and process, contributing to a relational consciousness that is central to an ethic of care. Findings also illustrate that PDPE can serve as a valuable window into experiences of reconnection, particularly useful for feminist researchers interested in learning more about enchantment and the transformational potential it holds. 相似文献

ABSTRACTThere is evident lineage between the concepts of teaching English as a foreign language (TEFL) and tourism, represented through evocative marketing material, the commoditisation of the TEFL product, teacher motivations and experiences. Yet, to date there has been little attention paid to this relationship. The amalgamation of the two concepts brings rise to the introduction of the niche form of tourism ‘TEFL tourism’, where the tourist travels outside of their usual environment to teach English as a foreign language and whose role shifts between tourist, educator and educatee at various points in their trip. The TEFL tourism phenomenon is explored through the use of a two-phase research approach employing the qualitative examination of blogs written by TEFL teachers and quantitative surveys. Drawing parallels with associated tourism forms including volunteer, education and philanthropic, it is concluded that TEFL tourism is an entity in its own right, with unique characteristics and motivations presented by TEFL tourists. The use of logistic regression facilitated the analysis of TEFL teacher types, presenting a typology classifying tourists as leisure-minded, philanthropy-minded, career-minded and expatriate-minded. This case-study examination facilitates initial comprehension of the TEFL tourism industry, providing basis for subsequent research to be undertaken to enable enhanced sustainable management of the TEFL industry worldwide. 相似文献
