Economic Valuation of Coastal and Marine Resources: Bohol Marine Triangle,Philippines

This article provides results on the net benefits generated from the natural resources in the Bohol Marine Triangle (BMT) in the Philippines. The BMT spans over 112,000 ha and its coastal ecosystems are rich in biodiversity and provide economic opportunities to the coastal communities. With a 10% discount rate, the accumulated total net benefits for the BMT resources over a 10-year period is US$11.54 million. Tourism and the municipal fisheries are the most important direct use values of the coastal and marine resources of the BMT accounting for 44% and 39% of the total net benefits. Annual revenues attributed to ecosystems were as follows: coral reefs, US$1.26 million; beach/intertidal area, US$1.12 million; marine waters, US$646,501; mangrove, US$239,561; and seagrass, US$105,990. The large market values indicate the dependence of the local community on the BMT coastal and marine resources. In the same way, non-market values show the important life-support functions of coastal and marine ecosystems. The net benefits reflect the magnitude of potential losses due to improper management of coastal and marine resources in the BMT. This valuation highlights the importance of the coastal services to the BMT economy and draws attention to the benefits the local stakeholders derive from BMT coastal resources. Policy measures can now take into account these values to justify a sufficient investment in coastal management efforts to sustain the flow of coastal services in the interest of current and future generations.     

民生警务背景下电动自行车治理困境与应对策略

大量的电动自行车违法行为给交通管理增加了繁重的压力的同时,也给民生警务改革、构建和谐警民关系带来了难题。在此背景下,文章首先阐述了新修订的《浙江省电动自行车管理条例》主要内容,接着分析了目前电动自行车治理存在民众对新《条例》认知不足、违法者不认同执法、电动自行车驾驶员安全意识不高和违规电动自行车生产销售等问题,最后有针对性地从宣传引导、加强执法协作和强化监管等方面提出了相应的对策建议。     

预防和减少建筑墙面几种裂缝的技术措施

通过对大量砖混结构的民用住宅、框架结构的办公楼等多种建筑的调查发现,多数建筑都存在着不同形式的裂缝,这些裂缝一旦出现便很难弥补,但许多裂缝是有规律可循的,对这些裂缝进行了总结。     

一个互动式“I—A—R”激励模型

社会转型导致人的存在状态的变化，经济利益成为人们活动的基本驱动力。通过对两种利益矛盾冲突的内在心理，和“奉献-索取”两种外显行为的矛盾的分析，构造了由“利益关系取向”、“奉献-索取取向”和“激励方式取向”组合成的互动式激励模型，即“I—A—R”模型。分析了模型的运作，即如何灵活权变地运用合适的激励方式的问题。运用实证分析和问卷调查，证明了个体的心理和行为倾向具有动态性。

Mobility, social exclusion and well-being: Exploring the links

Building on a growing research foundation, transport policy makers have begun to associate the ability to be mobile with having a role in the facilitation of social inclusion. However, the further connection to well-being is not as well understood. This paper explores the association between a person’s travel patterns, their risk of social exclusion and self-assessed well-being. Key influences on social exclusion are discussed, with trip making emerging as a significant influence. Trip making is not a significant direct influence on well-being but does exercise an indirect influence through the impact on risk of social exclusion. The modelling process enables a value for additional trips to be estimated, the value being about four times the values derived from conventional generated traffic approaches. Similar high values are found in separate metropolitan and regional case studies, confirming the significance of the results.
