It is found that, comparing with the unfavorable effect of internal fluctuations, the external noise activation is sometimes beneficial to the diffusion process. An optimal strength of external activation or correlation time of the internal fluctuation is expected for the diffusing particle to have a maximal probability to escape from the potential well.展开更多

Environmental ethics places restrictions on freedom in exercising ownership rights and pays more attention to ethical obligations to the environment. The anthropocentric approach should be avoided because it only sees the environment from its commercial angles to satisfy human interests. This research critically describes the reality of the utilization of traditional open spaces in Ubud to become an economic space. The rapid influence of global culture has implications for the practices of capitalist culture within the frame of the tourism industry, resulting in cultural industries, popular culture, hedonic lifestyles and consumerism. This study used a qualitative method. The data was obtained through observation, interviews, literature studies, and documents. The results of the study revealed how traditional open spaces were produced, distributed and consumed by the market. Traditional open spaces were commercialized, traded like goods and services. Traditional open spaces, such as paddy fields, cliffs, telajakan (front part of the house complex), city parks, domestic properties, backyards, cemeteries have been turned into economic spaces to satisfy the taste of tourists. Space is controlled and commodified by capital owners to feed their economic libido while disobeying environmental ethics.展开更多
