Exploring the issue of integrating logistics and traffic control in urban areas

This paper proposes an optimization framework for urban transportation networks’ (re-)design which explicitly takes into account the specific decision-making processes of ordinary users and logistic operators. Ordinary users are typically commuters whose travels consist of well-defined pairs of origin and destination points, while logistic operators make deliveries at multiple locations. Obviously, these two user classes have different objectives and scopes of action. These differences are seldom considered in traffic research since most models aggregate the flow demand in OD matrices and use assignment models to predict the response of all users as if the dynamics of their optimization processes were of the same nature. This work demonstrates that better results can be achieved if the particular features of each user class are included in the models. It potentially improves the estimation of the responses and allows managers to shape their control measures to address specific user needs.

公路滑坡综合整治处理设计

介绍了广东省公路K41+800—K41+860右侧边坡的整治处治。分析了边坡滑塌的起因,在分析的基础上提出了以预应力锚索和抗滑挡墙为主、护坡、拱架植草防护为辅的综合整治措施。实践证明,对于顺层且倾向于路基一侧的边坡以及由地质构造如断层控制的边坡,都有失稳的可能性,在设计时应除了对全坡面进行必要的防护外,还应根据计算分析结果对边坡进行有效可行的加固。本边坡滑塌整治至今效果良好,说明本文提出的"削坡减载、强身固脚"的综合措施是合理可行的。

Papahānaumokuākea: Integrating Culture in the Design and Management of one of the World's Largest Marine Protected Areas

Papahānaumokuākea Marine National Monument is one of the world's largest marine protected areas and was designated the first mixed conservation site in the United States due to its natural and cultural importance. It is also the world's first cultural seascape, being recognized for its continuing connections to indigenous people. As the westernmost place in the Hawaiian universe, many believe these islands and seas are the pathway that Native Hawaiians travel after death, returning to pō (night; realm of the gods). This intimate kinship has profound implications for contemporary management. Current management emphasizes integration of science, policy, cultural knowledge, traditions, and practices to create successful management strategies appropriate for both natural and cultural resources. This management is based on Native Hawaiian values and practices that incorporate observation and understanding of the natural world, indigenous principles and philosophies, cultural norms, community relationships, and unique epistemologies deeply imbedded in and formed by relationships of people with place. A cornerstone of this effort has been the direct involvement of cultural practitioners in policy, management, education, and research. This biocultural approach has led to more effective management of the monument and serves as a model for conservation around the world.
