The relationship between the ‘push’ and ‘pull’ factors of a tourist destination: the role of nationality – an analytical qualitative research approach

Using qualitative research techniques, this paper explores the relationship between the ‘push’ and ‘pull’ factors of a destination and the influence of nationality on these factors. These relationships were explored for a sample of 103 international tourists to Mauritius. The data were analysed by using (a) thematic analysis and (b) an analysis using the text analysis programme, CatPac. The results indicated relationships between specific motives, cognitive and affective images and it was also found that nationality has a strong influence on these variables. Different motives for visiting Mauritius were found to exist between different national groupings. Implications for use of thematic and content analysis, management of destination, marketing and tourist experiences are provided.     

Wildland Fire and Organic Discourse: Negotiating Place and Leisure Identity in a Changing Wildland Urban Interface

A lack of research on the conceptual intersection of leisure, place and wildland fire and its role in identity prompted this exploratory study. The purpose of this research was to gather evidence regarding how people negotiate identities under the threat of wildland fire. Qualitative interviews with 16 homeowners and recreationists who value leisure activities in undeveloped places in Colorado's Arapaho-Roosevelt National Forest were conducted. Results show that wildland fire plays a varied role in the identities of many of the research participants. Three dominant discourses of nature (i.e., humanist, protectionist and organic) helped explain these identity-related reactions to wildland fire. An understanding of the multidimensional aspects of place and leisure identity highlighted in this research could help land managers particularly related to the organic discourse.     

Place Meanings Ascribed to Marine Settings: The Case of the Great Barrier Reef Marine Park

Using data collected from in-depth interviews of recreational visitors to Australia's Great Barrier Reef Marine Park, place-related meanings ascribed to a marine environment are described. The usefulness of using symbolic interactionism to understand the creation of these meanings is also assessed. Ten meaning-themes emerged (aesthetic beauty, lack of built infrastructure/pristine environment, abundance and diversity of coral and other wildlife, unique natural resource, facilitation of desired recreation activity, safety and accessibility, curiosity and exploration, sense of connection to the natural world, escape from the everyday, and experiences with family and friends), and evidence supporting the utility of symbolic interactionism was identified. Using these findings, researchers may be better able to identify place meanings and the processes that create them.     

场所依恋、故地重游的本质内涵及其启示

总结了场所依恋的含义,分析了故地重游与场所依恋的关系,继而从逻辑和思辨角度深入分析了场所依恋的本质,提出了场所依恋和故地重游的本质是对生命的留恋和追忆的观点,最后论述了对于旅游区管理、项目创意以及规划设计上的启示和意义。     

试论桥梁灌注桩施工

水下混凝土灌注桩技术现在已经被广泛的应用在桥梁的施工当中。桥梁下部结构经常采用单桩单柱的结构形式,由于桩数较少,受力集中,负荷较大,桩身一旦发生严重缺陷很难采取补救措施,所以对大口径桥桩的成孔质量和灌注质量要求十分严格。     

How recreation involvement,place attachment and conservation commitment affect environmentally responsible behavior

This study examines a behavioral model using latent variables of place attachment, recreation involvement, conservation commitment and environmentally responsible behavior among tourists visiting wetlands. In total, 928 usable questionnaires were collected. Confirmatory factor analysis and structural equation modeling were applied to the data by using LISREL 8.70 for Windows. Analytical results, which further elucidate the behavioral models of nature-based tourism, suggest that place attachment, recreation involvement and conservation commitment critically impact environmentally responsible behavior. In this behavioral model, conservation commitment simultaneously and partially mediates the relationships between place attachment and environmentally responsible behavior and between recreation involvement and environmentally responsible behavior. A series of management implications are drawn, including the need to use this information via a visitor interpretation strategy, greater use of partnerships with local communities and businesses to spread the importance of wetlands and of environmentally friendly behavior, and the need to work with other wetlands to share the type of visitor motivations best suited to encourage environmentally friendly behavior.     

旅游产品的差异性与城市旅游中心地的区域结构

现代城市的发展不但促进了许多新的旅游中心地的产生，而且形成了不少新的城市旅游中心地的区域结构。这是现代旅游产业集聚的一大特征。本文把旅游消费者行为中关于多样化偏好和追求效用最大化的经济学理论，运用于城市旅游中心地的周边旅游目的地的区位结构研究。全文从消费者对一个周边旅游目的地做单一往返旅游、对全部周边旅游目的地分别做单一往返旅游以及对全部周边旅游目的地做链路旅游等三个方面来分析其总消费效用最大化问题，最后求得城市旅游中心地在总消费效用最大化前提下最优的两种基本区域结构。     

专业外语教学模式探析

专业外语教学不同于专门的基础外语教学和专业课教学．它要求教师必须将外语学习与专业学习结合起来开展教学．教学内容要具有广泛性和时效性，还要通过适时的外语讲解和多种形式的课堂实践增加实践教学内容．这样教师的专业外语教学水平才会得到提高。     

数字中国省域品牌形象构建——以“数字山东”为例

数字中国建设正在全国各地稳步推进，但是回顾以往研究发现，目前缺乏品牌视角的数字中国研究。作为区域品牌，每个数字中国省域品牌都有自己独特的品牌形象，具有特定的品牌利益和品牌个性。通过受众分析和问卷调查，对“数字山东”品牌形象进行识别，以智能作为数字山东的品牌利益，以刺激为核心塑造数字山东的品牌个性，推动形成数字时代山东睿智、创新、充满活力的区域形象。
