回族作为\"最熟悉的陌生人\",其关系建构问题近年来日益受到多个学科的关注。论文以\"关系经济地理学\"强调的情景性、路径依赖和权变性观点为思想来源,构建了回族社区关系建构的理论分析框架。案例研究发现,散杂居回族社区的关系建构是\"大尺度分散\"和\"小尺度集聚\"的地缘结构,\"族内强关系\"和\"族外弱关系\"的社会关系、基于资源禀赋和地理区位差异的特色经济网络,以及基于地方传统和路径依赖的教缘网络,在交互作用中产生和发展的,该解释框架对中国散杂居地区回族社区转型发展具有重要的理论价值。 相似文献

非物质文化遗产旅游性质的认识路径 总被引：5，自引：0，他引：5
在保护的前提下并受制于联合国教科文组织的界定,我们获得了一些关于非物质文化遗产旅游性质的概念。不仅在内容方面而且在认识路径上,非物质文化遗产资源表现出与常规旅游资源的较大差异。对于舶来的非物质文化遗产概念,我们需要用“认识路径”这样的关键词来固化保护意识。 相似文献

自20世纪七八十年代以来,国际学术界就开始寻找决定一个国家发展并富强起来的原因,其中制度安排的解释最为流行。中国的改革发生在社会主义条件下,是社会主义制度的自我完善,因此,中国的发展自然也离不开制度的安排。中国特色社会主义制度不但有利于统筹协调各方面的利益,而且能够有效地整合社会资源,集中力量办大事。正是有了这样的制度安排,才使我国的各项事业取得了举世瞩目的发展成就。 相似文献

Methods are described for modelling both the speeds and the driving forces of innovation processes, namely Critical Path Schedules and Cash Flow Curves respectively. The differences between innovations in modern industrial conditions and simpler societies are discussed, and the models applied to early innovations, but the data are too fragmentary to make quantitative models, although they can be used qualitatively to show general trends. In early societies the speeds were very slow but benefit/cost ratios very high, whereas the reverse tends to be true on average for modern innovations. Long delay times are often found in early innovation processes and these are determined by a wide variety of cultural factors. Seldom has the progress of the technology itself been on the “Critical Path” of innovation processes. The “Critical Path” and “Cash Flow” methods can also be used to study other, non-innovative, complex processes. 相似文献

移民搬迁型城乡融合是易地扶贫搬迁和城乡融合的有机契合,移民搬迁型城乡融合对搬迁户生计韧性的影响路径是城乡空间重构过程中的重要科学问题。本研究以搬迁户生计资本为中介变量,构建“移民搬迁型城乡融合→搬迁户生计资本→搬迁户生计韧性”分析框架。以西宁都市圈为研究靶区,采用结构方程模型分析移民搬迁型城乡融合对搬迁户生计韧性的影响路径。研究表明:①移民搬迁型城乡融合促进搬迁户的金融资本、社会资本、物质资本和人力资本增加,却导致搬迁户的自然资本减少;搬迁户的金融资本、社会资本、人力资本和物质资本促进搬迁户生计韧性增强,但搬迁户的自然资本却导致搬迁户生计韧性减弱。②搬迁户不同类型生计资本之间的相互作用强化了生计资本的中介效应。自然资本对金融资本具有正向作用;金融资本对社会资本和物质资本具有正向作用;社会资本对金融资本、人力资本和物质资本具有正向作用;人力资本对自然资本具有负向作用,对其他类型的生计资本均具有正向作用;物质资本对金融资本和社会资本具有正向作用。③移民搬迁型城乡融合通过改变搬迁户的自然资本、金融资本、社会资本、人力资本和物质资本,促进搬迁户生计韧性增强的路径系数分别为0.020、0.075、0.071、0.066和0.138。④增加搬迁户生计资本总量是提高搬迁户生计韧性的长远之计,优化搬迁户生计资本结构是提高搬迁户生计韧性的当务之急。 相似文献

Environmentally-related wear conditions and pathologies affecting the dentition of fossil lungfish from freshwater deposits in Australia have been analysed and compared with similar changes in the dentition of the living Australian lungfish, Neoceratodus forsten. Fossil populations from the Namba, Etadunna, Wipajiri and Katipiri formations in central Australia, and the Carl Creek Limestone and the Camfield beds in northern Australia were assessed. Tooth plates from populations of living lungfish from the Brisbane River and Enoggera Reservoir in southeast Queensland were analysed for comparison. Tooth plates were measured to determine the numbers of different age groups in each population. They were assessed for abrasion, attrition, spur and step wear, erosion and caries, and for trauma and pathological conditions such as malocclusion, hyperplasia, abscesses, osteopenia and parasitic damage. AH of these conditions are related to the environment where the fish lived, are found in living members of the group, and can be compared directly with those of fossil relatives. The results suggest that some of the fossil populations were at risk before climatic changes late in the Cainozoic destroyed their habitats. Some fossil lungfish populations, such as those of the Wipajiri Formation, exhibit active spawning and recruitment, good growth rates and a low incidence of disease and environmentally related damage to the tooth plates. Others, like those of the Katipiri and Namba Formations, include no young, and the adult fish were ageing and show environmentally-related damage to the dentition. Etadunna lungfish had active recruitment, but the tooth plates show a high incidence of attrition and caries. Riversleigh lungfish were actively spawning but did not grow large. Tooth plates from this latter deposit have a high incidence of pathological conditions. Fish from the Camfield Beds, where food was severely limiting, had little serious pathology but high levels of caries. Pathologies among living lungfish are common, but fossil fish were comparatively healthy, with few serious dental problems. Information from studies of fossil lungfish confirms that conservation of the few living species of lungfish depends on the maintenance of clean environments that provide adequate supplies of food and suitable sites for spawning and for the growth of young fish. 相似文献

The notion of path dependence has not yet been well explored as a tool for analysing landscape change. Within geography it is primarily economic geographers who have, up until now, shown a keen interest in this concept which stresses the role of social agency and institutions in understanding the development trajectories of regions. Further, the notion of path dependence usefully captures the idea of contingency in historical sequences. This article presents such a perspective on landscape change analysis, discussing two dominant types of sequences in path‐dependent systems. Self‐reinforcing sequences characterize the formation and long‐term reproduction of a given institutional pattern, while reactive sequences describe chains of temporally ordered and causally connected events. From a landscape point of view, by the former we can describe the fixity of practices, by the latter the particular development of (or changes in) landscapes. Within such a framework of path dependence analysis, examples from south‐eastern Latvia, the historical region of Latgale, are used to account for the institution of partible inheritance and to explain its impact on landscapes. The landscape biographies of two villages are studied in order to understand the particular key breaking points and the (series of) reactions that follow from these events. The challenge of using the tool of path dependence analysis lies in its openness for various interpretations, suggesting the need for supplementary theory. 相似文献

Encouraging environmental action by citizens in developed nations has become a major priority for governments who are seeking to reach environmental targets by exhorting individuals to participate in a range of behaviours to ameliorate the negative impact of their lifestyles. Such activities conventionally include energy saving, water conservation, waste management and forms of ‘green’ consumption. Current policy discourses are focused around a linear model of behaviour, which assumes that an awareness of environmental problems and knowledge of how to tackle them will lead to individual ameliorative actions. This paper explores these assumptions by applying a previously developed conceptual framework (Barr et al. 2001) to a range of environmental actions, to show how a variety of different factors influence environmental action. Using data from a major (UK) Economic and Social Research Council (ESRC) funded research project in Devon, United Kingdom, data on environmental actions collected during the project are interrogated to uncover the relationships between environmental actions and how these are influenced by values, personal situations and attitudes. The research demonstrates that environmental action is structured around people's everyday lifestyles (rather than a compartmentalized notion of behaviour) and that these have radically different antecedents. 相似文献
