Public Stakeholders' Perception of ICZM and Coastal Erosion in the Mediterranean

The Mediterranean area plays a pivotal role within the definition and implementation of regional strategies for integrated coastal zone management (ICZM). Under the umbrella of the Regional Framework Operation BeachMed-e, a research project was carried out in five Mediterranean EU regions (East Macedonia and Thrace in Greece, Lazio, Liguria, and Emilia Romagna in Italy and Languedoc-Roussillon in France), in order to study the different approaches to ICZM that have been applied and also to test new approaches to these regions. The aim of this article is to present and discuss the results of the common surveys conducted in order to investigate the institutional stakeholders’ perception on ICZM in the five Mediterranean regions considered. The results are presented region by region, while comparisons are carried out among regions. Summarizing the results it can be stated that some differences and common problems affecting the coastal decision-makers of the five Mediterranean regions considered were identified. Particularly, stakeholders involved in coastal management generally perceived a lack of collaboration and a poor information exchange in all the regions, resulting sometimes in a lack of awareness on coastal erosion issues.     

隧道纵向消防通风的对数理论

文章介绍了一种新的隧道防火通风理论.与目前通用理论不同的是,该模型没有从Froude相似准则出发,而是通过对基本热流体动力学方程组的简化、分析,揭示了火源放热率与隧道通风速度和隧道高度之间的逻辑关系,提出了以火势为特征的隧道火灾通风理论;依据这一理论,隧道通风临界速度为火势的对数函数,进而解释了大型隧道火灾中临界速度与火源放热率无关这一重要实验现象;利用新的火势概念,该理论给出了定量的火灾分类准则,并从数学上描述了各类火灾的物理特征;与现有实验数据比较,新理论无需任何实验修正,在所有火源放热率范围内成功地预测了隧道通风临界速度,从理论上克服了现有模型中临界速度随放热率无限增大的问题.由于新理论的二维性质,隧道侧壁面对防火通风的影响仍需进一步研究.     

Dealing with uncertainty and volatility in the port industry network: social and instrumental antecedents of “clique” survival

The recent proliferation of inter-firm collaborative linkages within the container port industry is progressively shaping a complex architecture of voluntary ties among terminal operators, i.e. an inter-organizational network. Within the overall industry network, some stable groups of densely interconnected firms emerge suggesting the existence of “cliques” where firms repeatedly cooperate with each other and develop strong and durable ties. The growing pressure exerted by economic uncertainty and market volatility on clique stability stimulates a fruitful academic debate on clique survival and its determinants. The present contribution investigates social and instrumental antecedents of clique survival, focusing on equity joint ventures engaged by terminal operators in a 10-year time frame (2002–2011). For this purpose, this study introduces a longitudinal network analysis of inter-firm relationships. Research hypotheses are tested performing binomial logistic regression analysis. In line with network theory assumptions, the outcomes corroborate the explanatory role of a number of social (i.e., cultural similarity and organizational mismatch) and instrumental (i.e., the presence of core firms within the clique and clique equality) antecedents in the survival of cliques. The results, indeed, bring valuable implications for both academics and practitioners.     

DEUS BOBBERSAKE V1

澳大利亚的改装商Deus算是令Vintage风格复古改装再度流行的始作俑者之一,他们的作品多是1940～1970年代流行的风格,比如Bobber。用于改装的车辆一般是在产在售的复古车型,强调手工金属质感。Deus同时也经营复古风格的服装和冲浪板,设计风格也是比较怀旧的澳大利亚海滩风格。摩托车对于Deus来说不单单是一个交通工具,还是一种生活方式。
