Philippine tourism growth is largely driven by visits to natural attractions. Addressing concerns on sustainability, environmental conservation, and local community involvement has become increasingly challenging. We identify the critical players in the industry and create a value chain framework for Philippine ecotourism that incorporates the quadruple bottom-line strategy to understand how sustainable tourism is being practiced among value chain participants. Findings have implications in the pursuit of sustainable ecotourism development in the country.  相似文献

Few studies have investigated the environmental factors of participants completing online self-report surveys, such as the presence of others and engagement in multitasking. The current study examined the environmental factors of 1023 participants drawn from two popular convenience populations—college students (n?=?512) and Mechanical Turk workers (n?=?511). All participants completed online measures of computer self-efficacy, the five-factor model of personality, and social desirability, as well as a questionnaire about their environment and activities when completing the measures. The two samples differed in terms of environmental factors, with college students significantly more likely to report: (1) being in a location other than their place of residence, (2) interacting with others, (3) being interrupted, (4) engaging in multitasking, (5) being under the influence of alcohol or other substances, and (6) completing the study using a laptop computer. The presence of others interacted with sample to predict personality and social desirability scores. Additionally, both presence of others and engaging in multitasking predicted longer completion time.

From 1999 to 2006, Canadian firms successfully diversified their exports to destinations beyond the United States while smaller firms increased their share in total exports. Both are explicit aims of the Trade Commissioner Service export promotion program. Exploiting assumptions from the treatment effects literature, we identify a causal, export‐boosting effect. In contrast with existing evidence for Latin American countries, the intensive margin effect—higher exports to existing product‐destination markets—dominates. Effects at the extensive margin—exporting more products to more destinations—are smaller and sensitive to identification assumptions. We interpret this evidence in light of trade models with heterogeneous firms.  相似文献

Destination attractiveness is an important stream of literature. Australia has been recognized as one of the world’s most attractive destinations. This study looked into international students’ perceptions of Australia as an attractive international tourism destination as well as their travel intention. A sample of 252 Chinese and Indian international students participated in the study. Students’ perceived destination attractiveness and how it influenced their travel intention, pleasure of travel and place attachment were investigated. The study also looked into perception differences between Chinese and Indian students using t-test and hierarchical regressions.  相似文献

This article focuses on a defining concept of modern surfing: localism. Using a qualitative ethnographic approach, the data for this study were collected using participant observation, field notes and interviews between 2008 and 2009 with a significant population of local surfers in a village location in Cornwall, South West of England, UK. Developing Bennett’s definition of localism, data suggested a benign form of localism and in conveying this, we make a number of associated observations. Our analysis considers how a process of Othering led to the construction of Established Insiders based primarily on location, rather than gender. These Established Insiders saw the need to protect their community and its way of life from Outsiders. The focal point for protection was the liminal space/phase that opened up on ‘their’ local waves, as it was through temporal space that communitas was generated and thus community sustained. We illustrate how benign localism was exacerbated by overcrowding and how local surfers’ experiences of localism made them aware of their becoming Outsiders in other surfing localities, modifying their behaviour accordingly. The paper also suggests that debates about localism need to view the concept as a continuum of attitudes and behaviours ranging from the benign to the heavy, and that attention needs paying to how localism varies between contexts and the ways in which localism may share social antecedents. Lastly, we highlight the utility of viewing the beach and wave as liminal spaces that give rise to communitas for those who surf it together regularly.  相似文献

This study employs mixed logit and latent class models to examine preferences for cattle traits with a focus on heterogeneity among cattle keepers, using choice experiment data of 506 cattle-keeping households in Kenya and Ethiopia. The findings indicate the existence of preference heterogeneity based on cattle production systems. Highly valued cattle traits for the cropping systems include traction fitness and trypanotolerance, while traits associated with herd increase are considered important in pastoral systems. Considering heterogeneity within population segments provides a framework for adapting breeding policy interventions to specific producer segments, by integrating preferred traits in a breed improvement program.  相似文献

In genetic improvement programs, candidates for breeders are ranked by the profitability of their offspring, expressed as a weighted sum of the genetic gain from selection. In this paper, we estimate the economic values of a genetic improvement program for Australian farmed saltwater crocodiles. A bioeconomic profit function for a representative breeding pair is used to determine the optimal slaughter age following genetic improvement in each selection objective. The results indicate that estimated farm profitability increases by nearly $A111 for a 1‐week reduction in juvenile slaughter age, $A78 for a 1 per cent increase in the proportion of first‐grade skins produced, and $A33 for an increase in the number of viable hatchlings per clutch. The implications of the analysis for the Australian crocodile industry and the limitations of the research are explored.  相似文献
