可持续发展的环境伦理

可持续发展的理论与实践要求促进了环境伦理学的发展。环境伦理也从人类中心主义的环境伦理与非人类中心主义的环境伦理的分野走向人类中心主义的环境伦理、非人类中心主义环境伦理和可持续发展的环境伦理的鼎足局面。可持续发展的环境伦理是合理人类中心主义环境伦理和非人类中心环境伦理并着眼于可持续发展的环境伦理，它要求人们在对待环境的行为中必须遵循善待自然、关注未来和规范行为的原则。

Growing up in a tourist destination: developing an environmental sensitivity

Abstract

This paper explores how the socio-cultural milieu of a community may foster a sense of environmental stewardship among children and young people. Ethnographic fieldwork, carried out in a popular tourist destination in Australia, revealed that the overt impacts of tourism activity such as littering provoke negative feelings among children and young people; these perceptions can in turn translate into a sensitivity towards the environment. While debated in some circles, a Significant Life Experiences (SLE) lens is useful in understanding children and young people’s lived experiences of – and sensitivity to - environmental issues in the communities where they are raised. SLE is employed in this article to explore how a sense of stewardship towards the environment is developed among children and young people growing up in a tourist destination. Findings suggest they actively contribute to protecting the environment in a variety of ways from regular beach clean ups and educating visiting tourists to participating in rallies and anti-development protests.     

Modeling of Normal Perforation of Reinforced Concrete Slabs by a Rigid Projectile

An analytical model on the normal perforation of reinforced concrete slabs is constructed. The effect of reinforcing bars is further hybridized in a general three-stage model consisting of initial cratering, tunnelling and shear plugging. Besides three dimensionless numbers, i. e. , the impact function /, the geometry function of projectile N and the dimensionless thickness of concrete target X, which are employed to predict the ballistic performance of perforation of concrete slabs, the reinforcement ratioρs of concrete and the tensile strength fs of reinforcing bars are considered as the other main factors influencing the perforation process. Simpler solutions of ballistic performances of normal perforation of reinforced concrete slabs are formulated. Theoretical predictions agree well with individual published experimental data.
