海洋海岛类国家公园是中国国家公园体系的重要类型之一,开展环境教育建设对于国家公园公益性的发挥具有重要作用。本文根据美国海峡群岛国家公园的实地考察及资料分析环境教育特点,总结环境教育实践经验,提出对中国海洋海岛国家公园环境教育体系建设的启示。结论如下:(1)海峡群岛国家公园环境教育具有生态系统及景观特殊性、教育场所弱可达性及教育方式多元性。(2)海峡群岛国家公园环境教育体系以教育内容和支撑体系为主体架构,其中教育内容划分为海岸、海岛、沿海(潮间带与泛洪区)、海下区域4类,支撑体系涵盖管理、资金、解说、传播、人才5个方面。(3)中国海洋海岛国家公园环境教育可在统筹管理、解说规划、人才培养等多方面予以借鉴,以探索符合中国国情的海洋海岛国家公园的环境教育建设模式。  相似文献

旅游发展是国家公园生态价值转化的重要路径与国家公园全民公益性的重要体现,周边社区居民是国家公园体制建设与旅游发展中的核心利益相关者之一,其生活质量影响国家公园生态保护与高质量发展。本文利用黄山风景区门户社区居民调查数据,探讨了处于探索阶段、参与阶段、发展阶段和巩固阶段等不同旅游生命周期阶段的社区居民生活质量差异及其成因。研究表明:(1)不同旅游发展阶段的社区居民生活质量差异显著,居民生活质量随社区旅游发展阶段演进而提升的现象具有滞后效应;(2)居民生计资本对不同旅游发展阶段社区居民生活质量的提升具有差异性;(3)随着社区旅游发展水平的不断提高,人力资本对居民生活质量的提升处于主导地位。  相似文献

在大力探索生态产品价值实现背景下,生态旅游作为公共产品,为推动生态产品价值实现和中国特色生态文明建设新模式的形成提供有力支撑。本研究选取南山国家公园线路为案例,以S-O-R理论为基础,构建生态旅游产品购买意愿模型,探究生态旅游产品在微信朋友圈购买意愿的内在机制。研究发现:(1)生态旅游产品在微信朋友圈的购买意愿存在“营销媒体特征—感知功利价值—购买意愿”和“社交媒体特征—感知享乐价值—购买意愿”两种形成机制;(2)生态旅游产品在微信朋友圈的购买意愿同时受到功利性因素和享乐性因素的影响,但功利性因素的影响占主导作用;(3)生态旅游产品的价格和产品图片的美观性对感知功利价值的影响较强;(4)微信朋友圈的社交存在感和微信好友的能力对感知享乐价值的影响较强;(5)不同人口学特征下,被调查者的购买意愿有显著差异。建议开展组合式营销、改善营销信息的内容和质量、保持高度的用户粘性、重视“专业形象”打造、针对主要客源市场“有的放矢”营销等实践,以促进南山国家公园生态旅游产品的价值实现。  相似文献

我国法学教育呈现出不少与司法考试相抵牾的欠衔接之处,二者在“教什么”和“考什么”、“怎么教”和“怎么考”方面的匹配程度亟需衔接。法学本科教学主要是通识教育,应关注价值、规范和事实三个维度;其中,规范学习是根本,案例学习和理论学习是规范学习的深化。法学本科教学课堂模式只有突出其模式自身的“比较优势”才能自证其合理性;以教师激情触发学生兴趣,使课堂教学成为一个真正有效的过程并获得良好的教与学的效果。  相似文献

The paper investigates HRM practices adopted by companies from the USA, Japan, Germany and France in UK companies that they have acquired. UK/UK acquisitions are used as a control. The research is based on a survey instrument applied to 201 companies and interviews with forty. It notes that there is some convergence of HRM practices, in that, for example, all countries researched employ performance-related pay and increase the amount of training in their new subsidiaries. It finds, however, that there is a distinct difference in the HRM practices employed by companies from each of the countries, influenced by the characteristic HR practices common to companies in the country of origin of the parent.  相似文献

Abstract

This article reports the findings of a year-long research project focused on the activity of boards of directors of twenty-two trusts from the British National Health Service (NHS). The evidence gathered through the use of semi-structured interviews, focus groups, workshops, feedback questionnaires and document analysis indicates that the behavioural dynamics of boards, affected by the dominance of the expert model, act as antecedents of their statutory functions and the implementation of different governance models. Only a portion of the boards involved has effectively incorporated in its modus operandi post-New Public Management (post-NPM) principles of governance.  相似文献

Policymakers and recreation site managers use changes in fee structure, either introducing park entrance fees or increasing existing ones, to generate revenues, improve services, and reduce damages associated with over-use. Increase in park usage fee, however, can make the park inaccessible to certain segments of tourists. Understanding park users' response to changes in fees and its implication on park use equity is, thus, important to achieving a park's full potential in a socially and environmentally responsible way. This information is crucial especially for developing countries, where the issue has received relatively less attention and national park systems are chronically underfunded. This paper contributes to the literature on park access fees by: empirically assessing park use equity between and among international and national tourists visiting Nyungwe National Park, Rwanda, and; developing an approach for determining predictors and mean willingness to pay values for park entrance. Results of our survey-based approach show a positive willingness to pay values for park entrance and fee increases. Our results also show that it is possible to raise revenue without exacerbating existing park use differences.  相似文献

Do increases in the food supply per person in a country, i.e., national food availability, contribute substantially to reductions in malnutrition among its children? This paper sets out to answer this controversial question using panel data from 63 developing countries over 1970–1996. This paper gives evidence in support of a statistically significant and strong positive impact of national food availability on child nutrition, finding that increased food supplies have resulted in significant reductions in malnutrition since the 1970s despite population increases over the period. However, per‐capita food supplies have a declining marginal impact: their effect is quite strong for countries with very low food availability (e.g., most countries in sub‐Saharan Africa and South Asia), but weak or non‐existent for those with high levels (e.g., most countries in the Near East and North Africa). Further, non‐food factors, such as women's education and status and the quality of health environments, are also important determinants of children's nutritional status. Depending on the state of food availability in any particular geographic area and relative costs, these factors may merit greater priority in policies to reduce malnutrition.  相似文献

Public field-afforestation schemes have been designed and widely implemented as a measure to alleviate uneven distribution, generate economic growth in rural areas and maintain or improve natural resources. The literature on forest management and planning has improved land-related information systems, allowing policy-makers to design and implement future policies on the allocation of forestland uses, and to forecast the land requirements of the target population more closely. The aim of this article is to empirically examine and validate the temporal and spatial land use changes and the socioeconomic effects linked to field-afforestation on private lands in the province of Lugo (Galicia, Northern Spain) at the municipal, parish and individual farm holding levels. Two main top-down field-afforestation programmes are reviewed in the study area: the national programme of public afforestations started with the implementation of Ley de Patrimonio Forestal del Estado (National Forest Estate Act; NFE) from 1941 to 2000, and the European aid scheme for forestry measures established under European Council Regulation No. 2080/1992 from 1993 to 1997. The results of a survey, targeted at 1355 farmers and conducted through questionnaires in the province of Lugo in 2004, complete the analysis of public intervention in forest management. The results indicate that the specific social, economic and environmental context of an agricultural and forestry area involves a differential heritage of land customs that determines a differential response model to forest programmes of land allocation and planning. Therefore, this must not be underestimated by the quantitative or qualitative general objectives of large-scale policies.  相似文献
