教育功能作为城市公园功能组成的重要部分,随着 人们日益增长的文化需求,城市公园环境教育的地位日益凸 显。为探究城市公园环境教育评估、游客参与以及解说满意度 之间的关系及作用机制,构建了三者之间的路径模型,以福州 市晋安公园为例,在对294位游客问卷调查的基础上,进行结 构方程验证。结果表明:1)修正后的模型中,建立关系指标 与游客参与相关性最强,有形性对解说满意度的影响最大,认 知层面最能反映环境教育评估;2)游客参与对解说满意度具 有显著正向影响,解说满意度对环境教育评估存在显著正向影 响,游客参与对环境教育评估有显著正向影响;未来公园在进 行环境教育功能提升时,应当将游客参与度以及解说系统满意 度纳入考量。  相似文献

Sufficient conditions for a unique price equilibrium, in terms of the uncertainty distribution and the state contingent consumer distributions, are given for spatial duopoly. Also considered are efficiency and endogenous locations for the symmetric case and comparative statics on price flexibility.  相似文献

When evaluating the risks of future invasions, we often have sparse information on the likelihood that a species will arrive, establish and spread in a new environment, and on the potential impacts should this occur. Conventional risk assessment, therefore, is limited in providing guidance in managing the risk of non-indigenous species (NIS). However, risk management decisions must be made facing these uncertainties to avoid high and irreversible impacts.We develop an integrated ecological economic modeling and deliberative multi-criteria evaluation (DMCE) approach to support group decision-making in risk prioritization, using an example of ten NIS that could potentially impact Australian plant industries. This innovative approach seeks to combine the advantages of dynamic modeling with the benefits of DMCE in assessing and communicating uncertainty. The model unveils the complexity of the socio-ecological system of biological invasion, with a scenario analysis designed to interactively communicate scientific uncertainty to decision-makers. The DMCE provides a structured approach to identifying stakeholders' key concerns in addressing economic, social, and environmental dimensions of NIS risk explicitly. Functioning as a platform for risk communication, the DMCE also offers an opportunity for diverse views to enter the decision-making process and for the negotiation of consensus consensuses.  相似文献

Based on how tourists interpret the destination experience and on attachment theory, this study investigates the influencing mechanism of tourists' happiness on revisit intention for traditional Chinese medicine (TCM) cultural tourism destinations. Three tourist samples confirm the three dimensions of tourists' happiness: positive emotions, engagement, and meaning. Two surveys were conducted to test the direct and indirect influence of tourists' happiness on revisit intention and the moderating role of tourists' health consciousness. The results show that tourists' happiness promotes memorable tourism experience and place attachment, in turn stimulating revisit intention. The results also support health consciousness as a significant moderator between happiness, place attachment, and revisit intention. The findings enrich theoretical understanding of tourists’ happiness and provide marketing and management advice for TCM cultural tourism destinations.  相似文献

为应对干旱、洪涝等降水事件给相关经济主体带来的风险,基于1953年1月至2016年12月福州市月均累积降水量数据,运用威尔克斯法对降水量进行建模,利用蒙特卡罗模法对降水期权进行定价从而得到降水期权价值,并提出发展我国降水期权的政策建议。  相似文献

将水权交易和面源污染控制有机结合,以种植面积、农业用水定额、污染物浓度为约束条件,运用边际分析方法建立农户灌溉施肥行为模型,分析水权交易和排污控制对农户行为的影响。结果表明:灌溉用水量与农作物价格成正相关,与交易水价和边际灌溉成本成负相关;一定范围内肥料施用量与农作物价格成正相关,与边际施肥成本或边际环境成本成负相关。模型证明,当农业用水定额内水权可交易时,水市场的存在和水价政策将激励农户减少灌水量,节约用水。  相似文献

加快实施最严格水资源管理制度的重要目标是形成以节水为目标的新的社会运行机制和社会治理模式。农民在农业灌溉中自发形成的用水组织是这一变革中的重要社会力量。通过对农民用水协会特征的分析,认为在"水权配置"的视角下,发展与规范农民用水组织,变原有农业用水过程中的行政管控为社会治理,是建立农业"节水型"社会并支持其良好运行的重要保障,并就如何健全农民用水组织的内部治理结构、克服农民用水组织自身的消极因素提出了建议。  相似文献

Pesticide mismanagement potentially has high risks for farmers, households living in the community and the environment. In Papua New Guinea where farming is the primary occupation, there is evidence of dangerous herbicide application methods being used by coffee growers. Using original survey data for coffee smallholders from four provinces, we assess the factors driving farmers' use of personal protective equipment when preparing and applying herbicides, and farmers' disposal of agro‐chemical containers. We control for households' demographic variables and measure the impact of farmers' training in pest and disease management. We use the special regressor method to estimate binary choice models featuring an endogenous binary regressor (training). Our results show that human capital (education) and training are important drivers of farmers' pesticide‐handling practices, with marginal effects estimated at 10 and 22 per cent, respectively.  相似文献

Dining out at a restaurant is one of the most important parts of travelers' tourism experience. The purpose of this research was to examine the antecedents and consequences of travelers' need for uniqueness (CNFU) in their restaurant experiences. Based on a literature review, three theoretical antecedents (perceived firm innovativeness (PFI), perceived firm uniqueness, and brand prestige) and three theoretical consequences (utilitarian value, hedonic value, and behavioral intentions) were proposed. During this process, it was theorized that consumers' uniqueness-seeking behaviors can be strengthened and/or weakened by three psychological moderators: attention to social comparison information (ATSCI), face consciousness, and materialism. By integrating the theoretical arguments, a structural model was proposed. The proposed model was tested using data collected from 379 travelers who had dined out at a luxury restaurant in the past three months. According to the data analysis results, PFI, perceived firm uniqueness, and brand prestige were all confirmed to be important factors in enhancing CNFU. Furthermore, it was determined that CNFU bears a positive impact on behavioral intentions, an impact that is mediated by perceived value. Lastly, the moderating roles of ATSCI and materialism were found to be significant. In the latter part of this research, managerial implications derived from the data analysis results are discussed.  相似文献

Research Summary: A learning‐by‐hiring approach is used to scrutinize scientists' mobility in relation to the recruiting firms' subsequent innovation output. Our starting point is that among firm hires, individuals with university research experience—hired from universities or firms—can be particularly valuable. However, conflicting institutional logics between academia and industry makes working with academic scientists challenging at times for firms. We suggest two solutions to this difficulty: hiring “ambidextrous” individuals with a mix of experience of university research and working for a technologically advanced firm, and a strong organizational research culture in the recruiting firm reflected by the presence of a scientist on the top management team. We track the mobility of R&D workers empirically using patent and linked employer‐employee data. Managerial Summary: An important way to make organizations more innovative is hiring individual researchers with the right types of skills and experience. We show that individuals with university research experience beyond their final degree are particularly likely to help boost firm‐level innovation output after hiring compared to R&D workers with other types of skills and experience. However, to obtain good returns to innovation from hiring such individuals, firms need a university research–friendly organizational culture when hiring individuals with university research experience, from either firms or academia.  相似文献
