Neil Smith, 1954–2012: “The Future is Indeed Radically Open”

Investors in single-family residential properties have played a crucial role in the United States foreclosure crisis. In this paper, we analyze investor behavior in the diverse urban housing market of Fulton County, Georgia. We examine the composition of buyers of lender-owned properties at two different stages of the foreclosure crisis, and analyze the intrametropolitan geography of investment. Results indicate that large-scale investors are most active in low-value housing submarkets with high poverty and vacancy rates.     

A geographic approach for combining social media and authoritative data towards identifying useful information for disaster management

In recent years, social media emerged as a potential resource to improve the management of crisis situations such as disasters triggered by natural hazards. Although there is a growing research body concerned with the analysis of the usage of social media during disasters, most previous work has concentrated on using social media as a stand-alone information source, whereas its combination with other information sources holds a still underexplored potential. This article presents an approach to enhance the identification of relevant messages from social media that relies upon the relations between georeferenced social media messages as Volunteered Geographic Information and geographic features of flood phenomena as derived from authoritative data (sensor data, hydrological data and digital elevation models). We apply this approach to examine the micro-blogging text messages of the Twitter platform (tweets) produced during the River Elbe Flood of June 2013 in Germany. This is performed by means of a statistical analysis aimed at identifying general spatial patterns in the occurrence of flood-related tweets that may be associated with proximity to and severity of flood events. The results show that messages near (up to 10 km) to severely flooded areas have a much higher probability of being related to floods. In this manner, we conclude that the geographic approach proposed here provides a reliable quantitative indicator of the usefulness of messages from social media by leveraging the existing knowledge about natural hazards such as floods, thus being valuable for disaster management in both crisis response and preventive monitoring.     

The opening of the Plio-Quaternary Gibraltar Strait: assessing the size of a cataclysm

Abstract

The widespread Lago-Mare facies show that the Mediterranean was fully isolated from the World Ocean at the end of the Messinian salinity crisis (MSC): the Plio-Quaternary Gibraltar Strait has no geographical feature in common with the Miocene Portals, which were continentalised before the end of the MSC. A copy of a budget model has been modified to study the infilling of the Mediterranean. The yearly Atlantic water supply follows an exponential increase law. The level of the basins does not change significantly during the 26 early years, but the refill of the Mediterranean basins is completed within the next 10–11 years. The high velocity of the flow of Atlantic water can be reconfirmed by hydraulic calculations. The morphological study of the area suggests that the Gibraltar Strait originates from an eastwards flowing stream, which drained the eastern slope of an emergent Gibraltar Isthmus to the Mediterranean Basins at the end of the Messinian. Similar canyons are still found in the marine topography towards the Alboran Sea. The present Spartel and Camarinal Sills both originate from the coeval mass sliding of the northern bank of the strait. The strait of Gibraltar results from the work of a stream, which managed water-piracy from an Ocean. © 2002 Éditions scientifiques et médicales Elsevier SAS. All rights reserved.     

The Catalan seismic crisis (1427 and 1428; NE Iberian Peninsula): Geological sources and earthquake triggering

The Catalan seismic crisis of the years 1427 and 1428 is one of the most destructive seismic episodes that happened in the northeastern Iberian Peninsula in historical times. The main earthquakes of this crisis occurred on March 19th 1427 in the zone around Amer (I_EMS-98 = VIII), May 15th 1427 in the vicinity of Olot (I_EMS-98 = VIII) and on February 2nd 1428 in the area close to Camprodon (I_EMS-98 = IX). There is much evidence that the Amer fault produced the first two events of this crisis, but is still uncertain which fault generated the earthquake on February 2nd 1428. Using newly available macroseismic data, the earthquake area sources of the three main earthquakes of the crisis have been obtained and they corroborate that the Amer fault may be the origin of the first two events. However, the area source corresponding to the last earthquake of the crisis cannot be associated to a single fault and indicates three possible candidates: the Vallfogona and Ribes-Camprodon thrusts and the Amer normal fault. Modeling of the Coulomb failure stress transfer has been performed to help determine the best candidate responsible for the February event. The results of the modeling points to: (a) a triggering relationship between the three main events of the crisis and (b) the Amer fault, or a similar extensional fault close and parallel to it, as the most probable origin of the earthquake on February 2nd 1428.     

金融发展影响区域绿色发展的机理——基于生态效率和空间计量的研究

近年来严重的雾霾在中国许多城市持续大面积出现,这敲响了提升区域发展绿色度的警钟。金融可以也应该在促进绿色发展中发挥重要作用。本文分析金融发展影响区域绿色发展的四个机理,利用生态效率反映区域绿色发展水平,运用空间杜宾模型和中国省域面板数据实证研究了各机理的相对重要性及其空间溢出效应。主要发现有：相对而言,企业监督效应和资本配置效应的作用更显著;前者对当地绿色发展的积极影响相对最大,但长期中才会对周边区域的绿色发展产生积极的空间溢出效应;后者对当地绿色发展具有显著影响,但空间溢出效应不显著;金融危机后资本支持效应和长期贷款的监督效应得到了加强,但证券市场的监督效应则反而具有负面影响;绿色金融效应及其空间溢出均不明显,暗示着有必要加强金融支持绿色产业和环境保护的力度。金融支持绿色发展的政策重点可能在于加强资金使用监督,而不仅是加大资金投入。     

西北地区建立节水型社会的对策研究

西北地区是我国水资源最为缺乏的地区之一,水资源短缺和利用不合理已成为该地区经济社会可持续发展的主要障碍。本文通过对西北地区水资源及其利用现状的分析和评价,提出实现该地区水资源可持续利用的关键是建立节水型社会,而建立节水型社会的重点在于建立、健全水资源的行政管理体制、市场运行机制和法制体系;建立科学合理的用水指标体系;大力调整农业产业结构。逐步形成节水型农业种植体系;大力调整工业产业结构。逐步建立节水型的工业体系。     

面对危机科学判断 战胜危机危中求变（机）——谈地勘业如何应对危机冲击渡过当前的经济低迷期兼谈“走出去”问题

由美国金融危机引发世界经济低迷对地勘行业在矿业市场等方面面造成负面影响,但也同时存在某些积极因素。面对危机,地勘单位应在工作方向、工作手段、机制体制等方面进一步转变。把握维护矿权和低成本获得矿权,规范净化地勘市场,促进管理、储备人才、积蓄力量,拓宽地勘业领域发展延伸产业,与大的矿业企业建立长期合作利益共同体及抓住“走出去”的艮好时机。地勘单位“走出去”到国外勘查开发矿产资源要切实掌握资源情况、切实掌握投资的软环境、需要配套的适应国际环境的人才、要有好的机制和体制、要有承担风险的心理准备和长期打算,力争在较短时间内构造起“政府支撑、企业动作”的“走出去”新机制、新体制。
