Malaysia is a multicultural, multireligious, and multiethnic country that is located in Southeast Asia. The social background of Malaysia as a multicultural state calls for the adoption of an alternative method to resolve community dispute which would offer solution and simultaneously promote harmonization in the society. Community mediation may be one of such alternative, if not the best method for interethnic relations. The government of Malaysia has introduced community mediation in Malaysia by providing training for community mediators through a pilot program, known as Rukun Tetangga (Peaceful Neighbor). The purpose of this program is to promote unity among the multi-races and multiethnic citizens. This paper will refer to the current practice of community mediation in Malaysia as provided by the National Unity Department in Peninsula Malaysia and the practice of community mediation in Singapore. It is hoped that by comparing the practices in both countries, suggestions and recommendations could be made to improve the practice of community mediation in Malaysia. 展开更多

The first example is from Sakhalin Island in the Russian Far East. It is connected with a construction of oil and gas pipelines through the mountainous terrain in Makarov region. The region has an active geotectonic history and is highly affected by uncontrolled erosion and extensive landslips. Basic principles of landslide hazard mitigation are presented. The second example is from a motorway construction in Azerbaijan. This motorway leads from Baku to Russia through a seismo-tectonically active area at the toe of Caucasian mountains and in some places is situated in deep cuts at the toe of high slopes. This unsuitable routing, together with seismic activity, led to a slope stability failure of a slope affected by recent tectonic movements near the village of Devechi. Stability conditions and designed remedy measures are presented. 展开更多

Aspects of time budgets, activity patterns and rut-related changes in behavior are well documented in temperate un-gulates; however, the application of this understanding to tropical and sub-tropical ungulate species has attracted less attention and remains an area that may re-shape our knowledge of ungulate behavior. Eld's deer Cervus eldi hainanus has a tropical and sub-tropical distribution on Hainan Island, China, and males have an extended rut exceeding five months during which they do not maintain harems or defend resources. We studied males from the only remaining population on Hainan Island, and describe rut-related changes in behavior by collecting data on time budgets and activity patterns. We show that male Eld's deer do not fol- low a strict crepuscular activity pattern, do not spend the majority of their time foraging and do not increase foraging nor display rut-induced hypophagia during rut, in obvious contrast to temperate ungulates. These results are discussed in light of current hy- potheses explaining the proximate mechanisms governing feeding time in ungulates, while appreciating the need for further re-search . 展开更多
