高层住宅含钢量新旧规范对比研究

随着房地产经济环境的变化,房地产开发商愈加重视结构的经济性和含钢量对造价的影响。2011版结构新规范的执行对结构的含钢量指标变化较大,直接影响结构经济性。本文根据新规范的实施,实例统计地震烈度6度区高层住宅含钢量的变化,统计建筑面积、钢筋级别、抗震等级在高层住宅中的影响情况,并且分析了含钢量的统计影响因素,以提供资料数据予房地产开发商造价控制以及结构工程师的结构优化。分析结果表明,新规范的执行使得含钢量和混凝土用量均增加5%以上,其影响不可忽视。     

The value contribution of strategic foresight: Insights from an empirical study of large European companies

This paper focuses on exploring the potential and empirically observable value creation of strategic foresight activities in firms. We first review the literature on strategic foresight, innovation management and strategic management in order to identify the potential value contributions. We use survey data from 77 large multinational firms to assess how much value is generated from formalized strategic foresight practices in these firms. We show that it is possible to capture value through (1) an enhanced capacity to perceive change, (2) an enhanced capacity to interpret and respond to change, (3) influencing other actors, (4) and through an enhanced capacity for organizational learning.

Urban recreation research: An overview

Despite the fact that the population of the United States ha shifted from largely rural to largely urban in this century, the commitment to research in recreation, inadequate as it is, has remained in the hinterlands. There is no critical mass of recreation researchers focusing on urban recreation as there now is focused on outdoor recreation. Urban recreation studies have been noncumulative in nature due to the wide range their sponsors, staff, substantive topics, lack of generalizability, and inevitable tensions between practitioners and researchers. Ironically, urban recreational research, and support of it, has diminished in this country at the same time that there has been an increasing concern for such information and knowledge. The future looks bleak insofar as the development of a strong, major, national urban recreation research program is concerned.

Tourism and climate change: a review of threats and adaptation strategies for Africa

The intersection of tourism and climate change has seen significant research over the past two decades, focusing particularly on issues of mitigation and adaptation in the global North. Research output has predominantly been centred on the Mediterranean and Nordic countries and number of localities in North America. The global South has seen significantly less investigation, despite having significantly lower adaptive capacity to the impacts of climate change, and numerous countries with rapidly growing tourism sectors. The African continent specifically has seen appreciably less research than other countries in the global South, despite arguably having the lowest adaptive capacity and projections of severe impacts of climate change to the tourism sector from temperature increases, changes in precipitation volume and sea level rise. This paper therefore presents a review of the existing literature on adaptation strategies of tourism sectors and participants in African countries. The crucial argument of this paper is in highlighting the need for an increase in research into the threats of climate change to tourism in African countries, identifying future research trajectories. The development of such knowledge would assist in the development of adaptation and mitigation strategies for these most vulnerable tourism economies.
