德阳水资源短缺原因分析

根据德阳水资源分布特征及利用状况，分析了德阳水资源短缺的4种基本类型（资源性、工程性、管理性和污染性），以及水资源短缺的原因，认为德阳水资源短缺是自然因素与人为因素共同作用的结果。解决资源性缺水的根本出路是节约用水和兴修水利工程。流域内控制性调蓄工程与灌区改造和配套工程的建设是解决工程性与设施性缺水的重点，管理性缺水要从区域内水资源统一调配、科学管理着手，并注重治理污染性缺水的加重和蔓延。     

Segregation and Marginalisation within Public Housing: The Disadvantaged in Bedok New Town,Singapore

This paper examines segregation within public housing in Bedok New Town, Singapore. The highly structured and regulated public housing sector, accommodating 86 per cent of the total Singapore population, provides an interesting look at the issue of 'choice' and 'constraint', and their implications for segregation. Using the index of dissimilarity to measure evenness of distribution and the P* index to measure social interaction and isolation, the data show that lower-income members of Indian ethnic background had become more segregated between 1980 and 1990. The eligibility criteria and allocation procedures pertaining to public housing help channel certain groups of residents into a narrow array of housing types in strictly defined locations. Particular socio-demographic features of lower-income Indians, coupled with their numerical inferiority, leads to a weak position within the housing market. The issue of constrained choice is especially relevant for this group of public housing residents.

Devolving Housing Policy and Practice in Northern Ireland 1998-2002

This paper reviews the effect of devolution on housing policy and practice in Northern Ireland. It outlines the history and context of devolution and housing policy in Northern Ireland, including the legacy and persistence of intense social conflict. Current devolution arrangements are reviewed, including the implications of enforced coalition for policy governance. The paper focuses on three dimensions of housing and housing-related policy development and implementation: social housing, especially the distinctive history and changing organisation of social housing provision; policies affecting the housing market, including the changing regime for spatial planning; and, regeneration and tenant participation. The paper argues that housing policy has tended to converge with policies in England, rather than moving towards a distinctively local agenda. Local political agendas remain dominated by disagreements over constitutional status thus policy formulation is determined more by officials than by elected politicians.     

Manually powered manufacture of keyed bricks

The production of bricks, one of the main components in conventional construction technology, has been carried out by either a hand moulding process or by a fully mechanized process. Both processes have limitations in developing countries. An alternative solution is the use of decentralized non-power-consuming brick making units, utilizing unconventional raw materials which do not require baking to develop strength. A manually energized brick making machine (MEBM) has proven the feasibility of extruding various mixes including a lime-fly ash-sand mixture. The production of bricks with a keyed cross-section is investigated using the MEBM to establish the functional and economic viabilities of the technology to create a construction technology which relies on abundant resources, unskilled labour and zero energy input. La production de briques, l'un des elements essentiels de la construction traditionnelle, est assuree soit par moulage manuel, soit par des procedes entierement mecanises. Les deux procedes montrent leurs limites dans les pays en voie de developpement. Une solution alternative consiste a utiliser des machines decentralisees ne consommant pas d'energie, faisant appel a des matieres premieres non conventionnelles qui n'exigent pas de cuisson pour donner la resistance a la brique. Une machine a fabriquer les briques mue par la force manuelle (manually energized brick making machine - MEBM) a prouve sa capacite a extruder differents melanges comportant un melange de chaux et de sable cendre. La production de briques a section creuse au moyen de la MEBM est a l'etude, afin d'etablir la faisabilite economique et fonctionnelle de cette technique propre a creer une technologie de construction basee sur des ressources abondantes, une main-d'oeuvre non qualifiee et une depense energetique nulle.

南水西调根本解决河西走廊资源性缺水的战略对策--阻止民勤成为第二个罗布泊

河西走廊是我国西部一块重要战略要地。解决水问题成为当地生产中的重中之重。通过研究，拟通过南水西调全面解决河西走廊地区的用水问题。方案引水近到河西，如有必要远可入新疆，亦可为现有西线补水。取水尽量减少或降低高坝大库，利用水流特点调水，充分发挥水流的作用，保证发电供水。从而改善北方电力结构，节省煤炭，改善大气环境，有利生态环境改良。由于水流走线高，可大面积植树造林，严防沙漠南侵。     

Forced Relocation vs. Voluntary Mobility: The Effects of Dispersal Programmes on Households

The deconcentration of poverty in the US has involved both voluntary mobility programmes for low-income households and involuntary relocation of families through government action. This paper examines the effects on families of these two different strategies. Using data on over 600 families in the Twin Cities region of Minneapolis/Saint Paul, the study reveals only sporadic support for the hypothesis that voluntary or involuntary participants in the deconcentration effort will report improvements in their living conditions, or report better conditions than a control group of public housing and Section 8 residents. Several possible explanations for the lack of programme effects are offered.     

比较住房政策与供需模式——我国保障性住房公共政策思考

目前我国保障性住房问题的根源在于保障性住房公共政策目标及其定位下的公共住房政策模式。研究从比较住房政策及供需模式角度出发,通过对其他国家公共住房模式实践经验的梳理与剖析,结合我国保障性住房现况,反思我国保障性住房目标政策模式,并借鉴国外的成功经验,提出完善我国保障性住房公共政策模式的相关建议,希望能引起更多学者对保障性住房建设的关注与研究。
