基于结构方程模型的城市旅游形象影响路径研究——以西安市为例

本文借鉴较为成熟的量表,结合专家与游客访谈,拟定测量变量及其项目。通过对西安市主要旅游景区(点)和酒店游客的问卷调查,获取相关的数据,进而运用SEM方法,拟构建目的地形象认知、情感形象、感知成本以及满意度(总体形象)组合的城市旅游形象影响路径的理论模型。根据多元回归分析结果,建立具有测量意义的路径关系。研究表明游客对西安城市旅游形象的评价影响有五条显著路径,其中形象认知对总体形象、情感形象和感知成本均有正向影响,但显著性差异不大,特别是对感知成本和总体形象影响较弱;情感形象对感知成本和总体形象有显著的正向影响;感知成本对总体形象有显著的正向影响。本研究部分印证了前期相关研究结论,但也反映出文化旅游城市形象影响路径的独特性。     

非物质文化遗产旅游性质的认识路径

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。     

A CONCEPTUAL FRAMEWORK FOR UNDERSTANDING AND ANALYZING ATTITUDES TOWARDS ENVIRONMENTAL BEHAVIOUR

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.     

贫困人口扶贫政策获得感评价与提升路径研究——以马斯洛需求层次理论为视角

以马斯洛需求层次理论为视角,运用大别山片区微观调研数据,通过理论分析与数理推导,构建结构方程模型,对贫困人口扶贫政策获得感进行综合评价与提升路径研究。结果表明：贫困人口物质需求、安全需求、社交需求、公平需求、能力需求在一定程度上得到满足后均能对其扶贫政策获得感的提升产生正向促进作用,且位于需求层次高低两端的物质需求与能力需求的正向促进作用最强;各维度正向促进作用在不同脱贫状态群体中差异性较大,能力需求对于已脱贫群体获得感提升的影响更为显著;大别山片区整体贫困人口扶贫政策获得感较高,各维度上指数得分差异性较小,但不同地区间存在一定差距。基于研究结果,本文提出一些贫困人口扶贫政策获得感提升路径。     

Sticky words? Towards a theory of rhetorical path dependency

Speech matters. Political actors are defined by what they say as much as by what they do but, with each rhetorical choice, they also narrow the range of rhetorical options open to them for the future. This paper examines the idea of path dependency, a well-established concept in the field of policy studies, and applies it to the study of political rhetoric. It argues that words are sticky, leaving political leaders caught between the desire to utilise fresh and engaging rhetoric to explain new policy choices and the reality that they cannot shake off the wording of their previous promises. In advancing a theory of rhetorical path dependency, the paper builds on the insights of both discursive institutionalism and rhetorical political analysis to suggest that whilst ideas are indeed vital to the shaping of institutions, the arguments that give those ideas shape can themselves be constrained by earlier choices.     

Hyperinflation as a catalyst of transformations: Path dependence through accelerated dynamics in post-First World War Austria

Hyperinflations are a modern phenomenon often associated with periods of transition. By accelerating the dynamics that govern the financial, political and private spheres of life, hyperinflations necessitate a quickened decision-making process in which alternative choices are eliminated. Using the example of Austria following the First World War, this article shows that hyperinflations are likely to have a path-determining effect on multiple levels. While periods of transitions offer the rare opportunity for countries to break with historical path dependence, hyperinflations carry the risk of creating new path dependence prematurely. By speeding up dynamics during transformative processes, hyperinflations eliminate possible alternatives that might otherwise have been chosen. Hyperinflations are thus best understood as neither the cause nor the consequence of transitions, but as their accelerating catalyst.     

New insights into ancient environments using dental characters in Australian Cenozoic lungfish

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.     

Geospatial modeling of pedestrian transportation networks: a case study from precolumbian Oaxaca,Mexico

Using accumulated cost surfaces and various pathfinding techniques within Geographic Information Systems (GIS) software, archaeologists and other spatial scientists have developed increasingly sophisticated models of human movement. Despite their utility, these approaches can be limited because standard GIS software cannot model movement (1) from many origins to many destinations or (2) without specific origins and destinations. Absent these capabilities, it is particularly difficult to model networks of movement over a given tract of land if you are interested in obtaining a more general sense of movement dynamics, not specific site-to-site patterns. In this paper, we present an innovative way of modeling past movement that generates both natural-looking networks and also indicates the degree of traffic that may have existed on any particular segment of those networks. The “From Everywhere to Everywhere” (FETE) model generates networks based on topography and landcover without requiring that origin and destination points be supplied in advance. We apply the FETE model to a case from the southern Mexican state of Oaxaca, a region that has extensive archaeological and ethnohistoric data sets that serve as a test of the efficacy of our technique. A comparison of the FETE output with known late precolumbian and early colonial movement corridors indicates that the method is effective and should be useful for modeling networks in other areas.

中国城镇土地非均衡扩张路径与治理策略研究

用经济学中的资源配置理论解释城镇土地非均衡扩张,根据城镇土地扩张的机理不同,把城镇土地分为工业用地、居住用地、基础设施用地,并分别考察了其非均衡扩张路径,在此基础上,从"制度环境-政绩目标-政策工具"三方面提出了非均衡扩张的治理策略。结果认为:招商引资过程中竞相以低地价供地导致了工业用地非均衡扩张;对土地财政的过分追逐导致了居住用地非均衡扩张;地方政府为攫取政治晋升资本,大兴城市基础设施建设导致了基础设施用地非均衡扩张;为系统控制城镇土地非均衡扩张,应在"制度环境-政绩目标-政策工具"三个层次上制定相关治理策略。
