Two facets of leisure, perceived determinants of well-being and enjoyment of common leisure activities, were investigated in 388 participants. For well-being, a principal components (PCA) analysis yielded five components: competence, relatedness and health, wealth, personal values, and freedom of choice. For the enjoyment of leisure activities, another PCA generated seven components: wellness, sedentary leisure, intellectual leisure, social leisure, routine activities, self-realization, and inner peace. Different leisure enjoyment of young adults (18–30 years old) in contrast to adults and seniors was attributed to social transformations as also predicted by several theories of social change. The relationship between the determinants of well-being and enjoyment of leisure activities was statistically significant but meaningfully debatable. 相似文献

The Carpathian Basin is one of the most vulnerable European regions in terms of potential climate change impacts on biodiversity. Its wide range of tourism activities make it uniquely suitable for assessing the effects of climate change on tourism. This research sought to create a Tourism Adaptation Portfolio (TAP) for the Szentendre micro-region in Hungary and to assemble an adaptation toolbox for current and future use by tourism organizations. The TAP contains practical, easy to implement solutions for key stakeholders in the sector by adaptation type (technology, management, behavior, education, policy). Surveys of local tourism suppliers showed that 70% said they were well informed, largely by the Internet, but 55% admitted to not knowing enough. The methodology outlined here is transferable and the process can be replicated elsewhere, supporting other regions in becoming climate-friendly tourism destinations, creating opportunities for uniquely positioning a region for consumers. The article provides a concise overview of tourism provider attitudes assessed through a questionnaire, shedding light on points of intervention, willingness to pay, main barriers and suitable adaptation instruments. The adaptive capacity of stakeholders is also discussed, which is indispensable for implementing successful practices in adaptation and maintaining the current level of environmental services. 相似文献

A clear understanding of residents’ attitudes towards tourism development and its determinants is a crucial pillar for designing tourism development strategies to promote sustainable development. The literature on the influence of host–tourist interactions and place attachment on residents’ attitudes towards tourism development in developing countries is still scarce. To extend knowledge in this field, this study aims at developing and testing a structural model to examine direct and indirect causal effects of place attachment, host–tourist interaction, and perceived positive and negative tourism impacts on the residents’ attitudes towards tourism development in an island tourism destination – Boa Vista Island in Cape Verde. Results suggest that the residents’ attitudes are positively affected by place attachment, host–tourist interaction, and perceived positive impacts; and negatively affected by perceived negative impacts. Host–tourist interaction emerges as the strongest (direct and indirect) determinant of the residents’ attitudes towards tourism development. Moreover, although both positive and negative perceptions of tourism impacts have significant impacts on the residents’ attitudes, the influence of the former is stronger than that of the latter. The paper ends with relevant theoretical and practical implications to promote positive residents’ attitudes towards tourism development in Boa Vista. 相似文献

Many rural areas have reinvented their territorial development through tourism, turning to vernacular heritage to ensure their future. Various models of heritage preservation and valorization are adopted where small-scale agriculture is no longer viable. Among them, ecomuseums and place-based labelization schemes transform rural heritage into an economic resource while remaining grounded in cultural and architectural preservation and identity transmission to future generations. Both face criticisms, including being decried as fostering the museumification and mythification of the rural, effectively holding back rural areas in an imagined and romanticized past rather than providing a vision for a sustainable future. The Association of the Most Beautiful Villages of France and the Ecomusée d'Alsace illustrate the debate. This investigation analyzes how these two initiatives challenge critics. It unveils their respective understandings of the future of rurality and their approach to promoting sustainable communities through tourism. By highlighting responses to tensions between valorizing the past and forward development in the countryside, findings reveal paradigm shifts from traditional habitat preservation to future-oriented architectural pedagogy in one case, while operational exigencies and normative quality principles mitigate opportunities in the other. 相似文献

This paper identifies sustainable initiatives reported by “sustainability-champion” hotels in the Dominican Republic, while contrasting them against the views of key stakeholders. We adapt and apply Hart and Milstein's Sustainable Value Framework, and complement it with a Critical Management Studies approach. Our analysis relies on a mixed-methods approach (non-hierarchical k-means cluster analysis, as well as thematic and content analysis). Findings indicate that most hotels are engaging more actively in present-oriented strategies such as pollution prevention (especially, the international hotels) and in product/service stewardship. However, in the future-oriented strategies, hotels owned by local investors show higher commitment to both clean technology and innovation, and to the sustainability vision (as the firm's growth path). In addition, although the views of multiple stakeholders show a clear acknowledgment of the hospitality industry's sustainability efforts (particularly regarding education and environmental protection), they also offer differing views about the ultimate impact and value of those efforts for them and for the broader society. Our study offers a new theoretical lens to explore multi-stakeholder approaches and offers practical implications for the Dominican Republic's National Strategy for Development 2010–2030, as well as implications that may be of use for other tourism-dependent countries. 相似文献

Municipalities and regions are often used as an object of tourism analysis at the subnational level. This occurs because administrative borders are used to implement tourism policies and collect statistical information. However, administrative boundaries may not always be suitable for studying tourism destinations at a local level. Sometimes, particularly in high-density tourism destinations, several differentiated tourism areas occupy a single municipality; tourism areas may, and often do, extend beyond municipal boundaries and tourism destinations may not occupy the whole of the municipal area. As such, a new level of analysis is often required: the micro-destination. There are few tourism concepts as imprecise as that of the destination. Therefore, the process of identifying and establishing the boundaries of a micro-destination is by no means a straightforward one. This paper presents six criteria for establishing the boundaries of this type of tourism area. Of these six, the two primary criteria used are: the concentration of tourism establishments; and tourism typologies and supply characteristics. These criteria have been applied as part of a pilot study in the Canary Islands. Statistical information for nine micro-destinations is generated using the geolocation of tourism establishments together with information obtained from both supply-side and demand-side surveys. 相似文献

This paper considers the combination of pollution taxes and abatement subsidies when some polluting firms procure their abatement
goods and services from an oligopolistic eco-industry. The regulator must here cope with two simultaneous price distortions:
one that comes from pollution and the other which is caused by the eco-industry’s market power. In this context, we show that
taxing emissions while subsidizing polluters’ abatement efforts cannot lead to first-best, but the opposite occurs provided
it is the eco-industry’s output which is subsidized. When public transfers also create distortions, welfare can be higher
if the regulator uses only an emission tax, but subsidizing abatement suppliers while taxing emissions remains optimal when
the eco-industry is concentrated. 相似文献

Onshore wind energy utilisation in Germany has developed very dynamically in the last decade. This has mainly been driven
by the renewable energy laws that systematically support the expansion of renewable energy in the electricity sector. In 2009
a revised law with increased feed-in tariffs for wind energy has come into force. Existing studies already predict a wide
range of development patterns under the Renewable Energy Sources Acts 2000 and 2004. This paper investigates the long term
impact of different feed-in tariffs implemented by the legislative authorities and it provides corresponding future development
patterns of onshore wind energy utilisation in Germany. The underlying System Dynamics model considers technical as well as
economic conditions and constraints. The approach and the model’s results are contrasted with other published predictions
qualitatively and quantitatively. This comparison shows that the model’s outcome lies in the range of predictions by existing
studies, but also shows some interesting differences.
Zusammenfassung Die Entwicklung der Windenergienutzung in Deutschland wahrend der letzten Dekade verlief sehr dynamisch. MagBgeblich dafur war die systematische Forde-rung mittels der Erneuerbare Energien Gesetze (EEG) bzw. deren Vorlaufer. Vom Jahr 2009 an gilt ein uberarbeitetes Gesetz, welches u.a. erhohte Einspeisever-gutungen furWindenergie beinhaltet.Vorliegende Studien, die sich mit derzu-kunftigen Entwicklung auseinandersetzten, zeigen bereits deutlich unterschied-liche Szenarien fur die Entwicklung unter dem EEG 2000 und 2004. Diese Arbeit setzt sich mit den langfristigen Auswirkungen der verschiedenen vom Gesetz-geber festgelegten Einspeisetarife auseinander und stellt entsprechend unter-schiedliche Ausbauszenarien fur die deutsche Onshore Windenergienutzung dar. Das zugrunde liegende System Dynamics Modell berucksichtigt dabei sowohl technische als auch okonomische Parameter. Der Ansatz sowie die Ergebnisse werden anderen veroffentlichten Prognosen gegenubergestellt. Die Ergebnisse liegen innerhalb der Spannbreite der anderen berucksichtigten Studien, zei-gen jedoch auch interessante Unterschiede.相似文献

If teachers are not equipped to teach Technology Education subject nationally and internationally, the continent of Africa will continue to bear the brunt of unsavoury results unless radical interventions are implemented to transform the situation. It is against this background that action research methods became a useful site-based support to empower Technology teachers at three sampled schools from Tshwane South Circuit in Gauteng Province of South Africa. The purpose of this study was to share fresh perspectives on how a sample of Technology teachers responded to content-related classroom practices during reflective action research activities that took place during community engagement contact sessions. These teachers, who are under qualified and unqualified to teach this subject, were engaged in circular and spiral action research cycles. The teachers’ engagement brought forth the development of Technology Education Cascading Theory. It was evident that community engagement activities served as a podium to transform teachers’ teaching of Technology Education and enhance learners’ achievement. The study was underpinned by cooperative enquiry theory and engaged participants in reflective practices of developmental action paradigm. Interaction with Technology Education teachers further revealed that most of them need their schools to budget for this Technology subject they are teaching. 相似文献
