Coastal areas are generally known as high-usage areas for residential, recreational, and tourism purposes. Coastal residents, as well as local visitors, therefore, can play an important role in protecting coastal resources. The purpose of this study was to identify important factors that could promote residents' environmentally responsible behavior (ERB). The two concepts, place attachment and attitudes toward tourism development (ATTD), were included to verify causal relationships of ERB. For data analysis, confirmatory factor analysis (CFA) and structural equation modeling (SEM) were conducted. Study results showed that place identity fully mediated the relationship between place dependence and ERB. With respect to the two dimensions of ATTD, there was a positive relationship between perceived benefits and ERB, while perceived concerns mediated this relationship. To promote ERB, the study emphasized the importance of developing place identity by providing diverse economical, socio-cultural, and recreational coastal benefits. In addition, involving those residents, who are positively and negatively impacted by tourism development, in the process of sustainable tourism development will develop more effective sustainable development strategies by reflecting local residents' opinions and preferences. 相似文献

Planning emergency evacuation operations in a proactive manner in public marine transportation systems is a critical success factor for passenger and crew safety. Despite the fact that there is a growing attention on safety issues for marine transportation systems, providing a real-time decision support for evacuation planning under different emergency conditions has not yet been addressed. In this context, this paper contributes to the related literature by providing a comprehensive methodology including simulation and statistical analysis along with a three-module decision support system (DSS) for ferryboat emergency evacuation. Emergency evacuation and fire environment are simulated via Maritime EXODUS V5.1 and SMARTFIRE V4.3, respectively. The methodology is applied to a real-life Ro-Ro ferry, and the results not only revealed significant factors on emergency evacuation performance, but also demonstrated the validity of the developed decision support system. 相似文献

威胁评估是舰艇对空防御指挥控制的关键环节之一。针对传统威胁评估方法在确定指标权重时采用常权重加权求和所带来的评估不合理的问题,将变权理论引入到舰艇对空防御的威胁评估中,构造状态变权向量表达式,使得权重随态势变化而做出相应调整。综合考虑目标属性与本舰防空武器性能,给出威胁评估指标体系,并结合“逼近于理想排序法”(TOPSIS)构建舰艇对空防御威胁评估模型。实例分析表明,该模型得到的评估结果较为科学合理,为舰艇对空防御威胁评估提供了理论与方法的参考。

The integration of climate change adaptation considerations into management of the coast poses major challenges for decision makers. This article reports on a case study undertaken in Christchurch Bay, UK, examining local capacity for strategic response to climate risks, with a particular focus on issues surrounding coastal defense. Drawing primarily on qualitative research with local and regional stakeholders, the analysis identifies fundamental disjunctures between generic concerns over climate change and the adaptive capacity of local management institutions. Closely linked with issues of scale, the problems highlighted here are likely to have broad and continuing relevance for future coastal management elsewhere. 相似文献
