通过对汉代的内向连弧纹镜的研究后发现,这种纹饰是古人用圆规分出的等分。进而对四神博局镜的背纹进行研究后发现,四神博局镜背纹中的几何纹饰也全部是采用圆规及直尺经过精心绘制而成。直至今日还可以看到,四神博局镜背纹中的几何纹饰,大都在某两条线的相交点上。从而说明,汉代的先民已具有了一定的机械制图水平。 相似文献

旅游意象塑造的操作指向论析——旅游文化设计探索 总被引:2,自引:2,他引:2
旅游意象具有形神兼备的特征,是外在的“象”与内在的“意”之结合体。因此,区域旅游意象的塑造,需要在问题诊断、地脉和文脉阐释基础之上,针对市场需求,依据对资源属性的认识,提炼出相应的意蕴内核,然后由内而外,构筑相应的产品和项目系统。作为旅游文化设计的一种探索,本文结合永康市、南通市以及洪泽县的实际,从理论和实践的结合上对旅游意象定位操作过程进行细化分析,希冀借此引发更多的思考。 相似文献

ABSTRACT Growing scientific literature evaluates the impact of traffic-calming devices in terms of mobility behavior and safety, but little is known about their perceived impact from the point of view of children. Our study asks children about their perceptions of different traffic-calming measures around their schools. It draws on data gathered through eight focus groups, followed by walking tours with Grade 6 children (11–12 years old) (n?=?65, 27 boys, 38 girls) from elementary schools in different urban contexts in Quebec, Canada. Qualitative analysis of the discussions shows that (a) vehicle speed is the main perceived threat for participant children; (b) children are confident about the effectiveness of self-enforcing traffic-calming devices that reshape the street geometry; and (c) they are skeptical about the effectiveness of ‘informative’ measures such as signs and lines (marked pavement). Our findings inform public policy for a more effective promotion of walking and cycling among children. 相似文献

COMPETING BY DESIGN, SPECIALIZATION AND CUSTOMIZATION: MANUFACTURING LOCKS IN THE WEST MIDLANDS (UK)
John R. Bryson Michael Taylor Richard Cooper 《Geografiska annaler. Series B, Human geography》2008,90(2):173-186
The past thirty years have seen major shifts and improvements in manufacturing productivity, bringing greater output but fewer jobs. As a result, manufacturing is now less visible in "post-industrial" societies. Nevertheless, manufacturing still matters in developed market economies but our understanding of manufacturing has failed to evolve with developments in the management and organization of production processes. This paper explores the lock industry in the West Midlands (UK), a traditional low-tech manufacturing sector. West Midlands lock companies that produced standardized, mass-produced products have experienced intensive competition from low-cost producers. Many of these firms have downsized their operations in the UK. Nevertheless, this is only one response to intensified competition. Lock firms located in the West Midlands are unable to compete on price and have shifted away from the production of mass-produced locks to concentrate on high value-added niche markets. The firms have developed inimitability strategies based around design, expertise, specialization, customization and nearness to market that assist them in maintaining their revenue and profit streams. Niche manufacturers have been far less susceptible and relatively immune to foreign competition and they continue to diversify product ranges by targeting specialist end-users. The emphasis is on producing high-quality locks in small batches that can be produced just-in-time to meet customers' requirements. The continued survival of these lock firms is based upon a strategy that includes the development of product-based competitive advantage combined with locational advantage and supported by efficient, responsive and customer-focused manufacturing processes. 相似文献

ABSTRACTThe existence of biological information systems is generally taken as given in discussions of their function. However, any theory of such systems must be considered incomplete unless it can also explain how the system comes to exist. This article describes the ways in which complex functional systems in general can be created through design, self-assembly and evolution. The differences and relationship between physical and informational entities, organization, processes and dimensionality are also discussed. Through comparison with information technologies, whose origins we understand, conclusions are drawn concerning the creation of functional biological neural networks: specifically, that this involves the self-assembly of information entities into a number of strongly emergent levels of organization. Finally, potential approaches are considered to overcome the hurdles to scientific investigation of emergent information-based systems and the processes by which they are created. 相似文献

This article seeks to contribute to debates about the mobile nature of contemporary economic practice, through a discussion of some key themes in the evolution of airport hotels as business spaces. It argues that despite being emblematic of a hypermobile business elite, the nature of hotels as business spaces requires careful unpacking. The article begins by discussing the evolution of the airport hotel, charting the shift from basic lodging standards to recent developments of five star airport hotels. It then seeks to explain the locational geographies of airport hotel development, in response to these new trends. Finally, the article describes how the business traveller is conceived of and (speculatively) catered for by airport hotel operators and designers within a discourse of connectivity, before providing some counter-examples of how such claims fail to address the hotel's place within the complexity of airport spatial organization. 相似文献

ABSTRACTWhile interrelated issues and challenges can only expand, the study of foreign policy in Australia is not a very healthy discipline. While not wholly wedged on life-support, there are genuine grounds for concern about the decline of Australian foreign policy (AFP) as a subject for serious academic concentration and its position as a marginalised topic of analysis. Unfortunately, attempts to reinvigorate the field continue to contend with a number of ingrained biases. AFP can be incorrectly dismissed as muddled and marginal while major debate points in the field are often glibly portrayed as broadly settled. This is despite the that fact that it can provide unique insights into policy-making in the twenty-first century while teaching students the benefits of problem-solving through a multi-disciplinary lens. Additionally, there is an ever-changing, contested set of knowledge that future leaders will need to consider in order to be successful, critical thinkers in a multi-agency environment. This will continue to incorporate an evolving variety of significant issues that constitute both conventional and unconventional threats to national interests. 相似文献

The objective of this paper is to make explicit the linkages between specific characteristics in the urban built environment, moderate physical activity (in particular walking and cycling), and public health. The review will take place at three different scales — the region, the city and the city‐block. At all three scales, the main interest is placed on accessibility, with the recognition that if distances are short enough and there is high connectivity within neighbourhoods, people might be encouraged to walk or cycle. The paper will draw on urban built environment characteristics from a number of Michigan municipalities, including Detroit, Ann Arbor, Birmingham, East Lansing and Okemos. 相似文献

Reading places is integrally linked to geographical studies. One of the oldest Western formulations of place is chora, which was introduced in Plato's Timaeus and has thereafter contributed to a rich tradition of interpretations. The geographical interest in chora has gradually increased as it has proven its value in making sense of the flowing conditions of contemporary social change. The gradual turn towards chora is also due to intense methodological rethinking in geography during recent decades. This article discusses the latest formulations of the geographies of chora, and focuses especially on the interpretations inspired by Jacques Derrida and Julia Kristeva. Their formulations of chora, including succeeding critiques, have encouraged us to rethink places of co‐design and re‐membering as illustrations of the paradoxes of chora as a ‘place in‐between’. 相似文献
