Initiatives in Philippine Coastal Management: An Overview

Standardized and free-format questionnaires on the state of coastal management were fielded to coastal management practitioners during three workshops and a national feedback and recommendation workshop. The most commonly cited responses were identified for each of 13 political regions and overall trends were identified. Management frameworks frequently included research, community organizing, education, livelihood, resource enhancement, resource protection, regulation, and networking components. Gender issues, documentation, and infrastructure investment were rare. The most commonly perceived environmental problem was illegal/ destructive fishing and its associated overfishing and low fish catch. The most commonly cited socioeconomic problem was the inadequacy of law enforcement. The best monitored variables were usually those related to environmental management: status and change of habitats, resources, and degree of enforcement/patrolling activities. The most common nonregulatory enhancement, aside from environmental education (which is the most popular), was mangrove reforestation. In terms of regulations, the majority of the respondents have reportedly formulated an integrated coastal management plan. In practice, regulating destructive and illegal fishing practices and then the establishment of fish sanctuaries are the next most implemented. The most popular quality-of-life enhancement strategies focused on the improvement of sustainable fishing as a livelihood and on a variety of supplementary livelihoods. The most usual institutional intervention being implemented was the setting up of local community people's organizations. Major factors which may influence success or failure of coastal management and recommendations on research, community organizing and livelihood, legislation and policies, implementation and coordination, and networking are also summarized.

Mixed Logit模型及其在交通方式分担中的应用研究

离散选择模型的典型代表Logit模型简洁易用的特点使其在经济、交通等领域得到了广泛的应用，但同时Logit模型的两个重要缺陷限制了其应用范围。在分析了Logit模型固有的两个缺陷和Mixed Logit模型的良好性质后，比较了Logit模型与Mixed Logit模型的差异，对Mixed Logit模型的算法进行了研究，并借助SAS统计软件提供的仿真算法给出了详细的工程实践应用范例。结果表明，Mixed Logit模型有着更丰富的物理含义，对个人出行交通方式选择行为的描述更符合实际。     

FEM/BEM在轮胎振动和噪声特性分析中的应用

基于ABAQUS和SYSNOISE程序,给出了分析轮胎振动和噪声特性的有限元和边界元模型及完整方法（FEM/BEM）,并以此模型和方法对某半钢子午胎进行了模态分析,计算其在激励作用下的辐射声场.计算结果表明,只要有通过试验获得的轮胎在滚动过程中所受到的真实激励谱,利用本文的方法即可对轮胎的振动噪声进行预报.

面向21世纪的海事控制理论探讨：船舶营运安全的基本要素结构

ＩＭＯ自成立以来始终致力于减少船舶事故。１９９８年实施的ＩＳＭ规则和ＳＴＣＷ７８／９５公约,以及即将遍布全球的ＰＳＣ网,能否有效地降低海事数量？如何控制“人为因素”？如何控制２１世纪的海事？经分析,提出了船舶营运安全的基本要素结构：“人－机－环境－管理”理论假说。经检验,假说便于全面查找事故原因和预防措施,便于分析和弥补ＩＭＯ现行安全措施的不足,方便了海上安全学科体系的构建。进而提出了包含该理论的海事控制策略建议。为将海事控制由经验型的事后性纠正,上升为科学型的事前性预防,提供了一种研究和控制模式

The Impact of Recreation on Barrier Islands: A Case Study on Masonboro Island

Since 1992, coastal researchers at the University of North Carolina at Wilmington have been documenting the impacts of human recreational use on Masonboro Island, a component of the North Carolina National Estuarine Research Reserve, and the subsequent natural processes that mitigate these impacts. Both short-term and long-term natural mitigational processes were identified. The effects of these processes were found to be much more rapid than similar impacts on typical terrestrial settings. However, careful examination of the data suggests that both physical location of the impact site and natural variability of weather patterns and events play a role. Management implications of these findings are proposed.
