Xixth International Congress of Photogrammetry and Remote Sensing

The XIXth International Congress of Photogrammetry and Remote Sensing was held at the Amsterdam RAI International Exhibition and Congress Centre, the Netherlands, from 16th to 23rd July 2000. Reports are given on the Congress as a whole, including the General Assembly, some Technical Commission activities and the Congress Exhibition. Papers from the Congress are published in the International Archives of Photogrammetry and Remote Sensing, 33.     

'Lunch is for wimps': what drives parents to work long hours in 'successful' British and US cities?

This paper reflects on the impact of long working hours on home–work–family reconciliation from a household perspective. It focuses on discrete interactions between long working hours for households with two parents engaged in paid employment, raising awareness of the integrated nature of work–life balance. Attention is paid to the 'strong economy paradox' confronting dual earning households in 'successful' cities. Evidence is presented to suggest limited resistance to long hours as well as diverse ways one partner adapts their mode of employment to fit the constraints of the other.     

Convergence or divergence?: Status and prospects for US climate strategy

The objective of this paper is to assess recent developments and prospects for future changes in United States (US) climate strategy. In doing so, the paper explores some of the key factors that have shaped strategies and policies to date, distinguishing between factors related to institutional and governance structures, linkages between science and policy, energy technology and the role of interest groups. Against this background, the paper attempts to explore future development paths for US climate policy. More specifically, the paper assesses opportunities for policy changes compared to the preferences of the current administration, and the prospects for future linkages between US and international climate change strategies. In brief, the paper argues that substantial changes are unlikely to take place in the near to medium term, leaving open, however, the possibility of wide-ranging changes in domestic politics or major incidents that could facilitate a shift in the perceived need for near-term action.     

当代美国地理学与可持续发展的理论、实践--基于人地关系论的分析

人地关系论是地理学最基本的理论。可持续发展理论与人地关系论一脉相承，是人地关系论的继承、变革和新发展。该文基于《重新发现地理学》的内容，借助中国地理学者对人地关系论与可持续发展关系的研究成果，以人地关系论来看待有人地关系研究深刻历史基础的美国当代地理学在可持续发展研究中的理论与实践。     

“从最高到最深”—从第17届国际沉积学大会看沉积学研究前沿

第17届国际沉积学大会于2006年8月27日至9月1日在日本福冈市召开。做为四年一次的国际沉积学盛会,大会讨论了微生物过程和沉积成岩作用、深海与陆缘沉积过程及产物、沉积记录与重大地质环境演化、火山-沉积大地构造,以及与人类活动密切相关的环境沉积学与资源问题等热点领域,其中大多将会继续成为未来若干年内国际沉积学的重要发展方向,并可能成为今后理论沉积学创新的重要生长点。但是在本次大会上,对陆相（或非海相）沉积与大陆构造、活动古地理、盆地流体动力学及相关成岩作用的研究并未形成热点。与国际沉积学研究强国相比,认为我国沉积学研究是危机与机会共存;我们不仅在服务国民经济方面,而且在国际沉积学前沿研究领域应该占有重要地位。      

US and EU experiences of tax incentives

The purpose of this paper is to shed light on the controversial issue of regional development incentives. Although extensive research has been conducted, a review of the literature gives an inconclusive answer to whether economic incentives are effective. Why do researchers arrive at different conclusions, even after analysing the same programmes? Among the problems that we find, for example, is the fact that for some researchers 'effective' means the significant location of new firms in targeted areas, while for others the creation of jobs regardless of whether new firms are arriving in a significant fashion. Furthermore, as we elaborate, the selection of an econometric model will have a significant impact on expected results. Different models, with different limitations, will lead researchers to evaluate the same incentive programme but arrive at different conclusions regarding its effectiveness. The contribution of the paper is to inform policymakers about the potential opportunities and pitfalls when designing incentive strategies. This is particularly relevant, given that both the US and Europe have been promoting incentives as a tool for regional economic development.     

Impact of hurricanes storm surges on the groundwater resources

Ocean surges onto coastal lowlands caused by tropical and extra tropical storms, tsunamis, and sea level rise affect all coastal lowlands and present a threat to drinking water resources of many coastal residents. In 2005, two such storms, Hurricanes Katrina and Rita struck the Gulf Coast of the US. Since September 2005, water samples have been collected from water wells impacted by the hurricanes’ storm surges along the north shore of Lake Pontchartrain in southeastern Louisiana. The private and public water wells tested were submerged by 0.6–4.5 m of surging saltwater for several hours. The wells’ casing and/or the associated plumbing were severely damaged. Water samples were collected to determine if storm surge water inundated the well casing and, if so, its effect on water quality within the shallow aquifers of the Southern Hills Aquifer System. In addition, the samples were used to determine if the impact on water quality may have long-term implication for public health. Laboratory testing for several indicator parameters (Ca/Mg, Cl/Si, chloride, boron, specific conductance and bacteria) indicates that surge water entered water wells’ casing and the screened aquifer. Analysis of the groundwater shows a decrease in the Ca/Mg ratio right after the storm and then a return toward pre-Katrina values. Chloride concentrations were elevated right after Katrina and Rita, and then decreased downward toward pre-Katrina values. From September 2005 to June 2006, the wells showed improvement in all the saltwater intrusion indicators.     

The sustained yield forest management act and the roots of environmental conflict in Northern New Mexico

Recent research on environmental conflict in New Mexico has focused on racial and ethnic conflict between environmentalists and Hispanic loggers as a means to explain the trajectory of environmental struggle and the failure of Hispano/environmentalist coalitions opposing Forest Service management policies. This paper seeks to extend this explanation by considering the constraining role of federal legislation, institutional management and commercial resource exploitation that limited opportunities for Hispano/environmental collaborative challenges to federal resource management arrangements. I analyze the foundations of sustained yield forestry on the Carson National Forest in northern New Mexico though a focus on the legal construction of sustained yield policies and the practices of implementing sustained yield on the Vallecitos Federal Sustained Yield Unit, a special timber production sub-unit of the Carson. The paper illustrates how the deployment of sustained yield forestry in New Mexico produced not only conditions of production favorable to commercial timber operators, but also established a complex and contradictory regulatory environment that effectively constrained collaborative efforts between environmentalists and small-scale loggers in their efforts to construct alternative futures for resource management in the region.
