Reflecting on a Decade of Australian Social Housing Policy: Changes in Supply and Geography, 2001–2011

This paper compares the intent of three Australian social housing policy interventions in the decade to 2011 with outcomes shown in time series data from the Australian Bureau of Statistics Census. The three policy interventions are the supply stimulus that occurred in 2009 with funding to construct almost 20 000 new social housing dwellings by 2012, the push to diversify social housing supply through the transfer of public housing stock to community not‐for‐profit housing providers, and the physical renewal of public housing estates to reduce concentrations of social deprivation. Its aims are threefold: to understand how the supply and geography of social housing dwellings has changed over the past decade; to relate these changes to the objectives of social housing policy in the time period; and to identify issues for the future of social housing in Australia emerging from identified disparities between policy rhetoric and supply reality. The paper employs quantitative analysis of social housing supply for all of Australia and mapping of social housing supply changes in the east‐coast mainland state capital cities. This analysis reveals the overall stagnation of social housing supply in Australia over the previous decade, combined with evidence of stock loss in areas of renewal in some cities.     

LABOUR FORCE GROWTH IN SINGAPORE

Singapore's labour force participation rates are at high levels. Age-specific rates, especially of men, have approached those of developed countries. The current very low total fertility rate of 1.25 would have major implications for Singapore's labour supply and economy in a closed population. Multi-pronged approaches such as measures to increase fertility, increase labour force participation, and to augment the local workforce with migrants are discussed. In the context of Singapore's physical land constraint, continued growth in the labour force in the long term would be challenging. Future gross domestic product growth is likely to be more sustainable via labour productivity growth. Identifying new niche areas of growth and having a nimble and quality workforce would become more important than labour force growth.     

Apatite grain boundary morphology and its response to low-temperature fluid infiltration in crystalline basement

Apatite grain boundaries on fractured rock surfaces have been examined in an amphibolite facies regional metamorphic granite gneiss from the central Swiss Alps. The morphology of apatite has been characterized using a scanning electron microscope and matched to surface textures in adjoining silicates. Apatites show a wide variety of different surface features ranging from planar crystal faces, to small-scale ridges and dimples, to extensive irregular pitting. Many of these features form in response to the periodic infiltration of fluids along open grain boundaries during the cooling history of the gneiss. Apatite shows evidence of both dissolution and re-precipitation that is controlled by the nature of the grain boundary, the structure of the adjoining silicate phase and the alteration of the host rock. Fracturing occurs in a range of retrograde conditions and is common both within the apatite and along grain boundaries. This coupled to the evidence of fluid interaction with mineral surfaces suggests that extensive permeable networks may be typical of cooling crystalline basement rocks. Grain boundary textures have the potential to reveal a unique record of fluid infiltration in the crust that would be very difficult to decipher using traditional petrographic methods.     

北京市公共服务设施供需协调发展的时空演化特征——以教育医疗设施为例

公共服务设施的优化配置是构建和谐社会、改善民生的内在要求。本文通过构建协调发展度模型,对北京市2001年和2012年16个区县教育医疗设施供需关系及二者协调发展的时空演化特征进行研究。研究认为:①教育设施"供不应需",供需差距增大;协调发展等级总体较低且有下降趋势;协调发展水平由"东高西低"向"南高北低"格局演变,空间差异增大。②医疗设施"供不应需",供需差距缩小;供需协调发展等级较低但有上升趋势,空间格局由"中心集聚"向"南高北低"演变,空间差异减小。     

公交站点可达性测度及其在停车分区中的应用

考虑公交与小汽车方式间的可达性差异,提出了依据公交服务水平调控小汽车可达性的停车分区思路,以期实现对小汽车方式的合理限制,支持城市公交优先发展。首先根据居民出行对不同类型公交站点具有不同可达性需求,将以需求点为圆心、站点时空可接近距离为半径的覆盖范围作为基本分析单元,构建基于微观个体时空约束下的公交站点可达性测度模型。其次借助ArcGIS,以昆明市公交网络数据为基础,对站点可达性空间分布特征进行可视化分析,所得结果与城市用地开发整体特征相吻合,验证了模型的合理性。最后以公交可达性水平为主要依据划分停车供给分区,从而对不同分区停车泊位供给的科学配置提供支撑。     

试论汉代的仓囷明器与储粮技术

作者从汉墓中出土的陶质仓困建筑明器,以及汉画像中所见的粮仓建筑资料中撷取若干,初步探讨了汉代地上粮仓建筑的形制以及当时的储粮技术等问题。     

明清时期潮州粮食供给地区及路线考

明清时期, 潮州地区由于商品经济的发展, 粮食日益不能自给, 不得不到本地区之外购买粮食。随着粮食需求的不断增大, 江西赣州, 广东雷州、琼州、高州, 福建厦门、台湾, 东南亚暹罗、越南等国先后成为潮州粮食的供给地。粮食供给地的变化, 引起贸易路线的变迁。潮州粮食贸易亦与潮州华侨出国有很大关系, 潮州的粮食贸易形成自己独特的原因和规律。     

陕西省农村土地流转迟缓的供求影响因素与机制探析

农村土地流转长期受到决策者的鼓励,但我国农村土地使用权流转率一直偏低,西部地区尤其如此。本文试图以陕西省为例,通过问卷调查和访谈,分析农地社会保障功能等因素影响农地使用权流转率的作用机制;并从供给和需求两个方面,分析了经济落后地区农村土地使用权流转率偏低的原因。研究结果表明,农地流转受到现行的以提供社会保障为基本目的的农地制度的约束,任何旨在提高农地流转率的改革措施,都必须考虑现行农地制度的社会保障功能和地区差异,实行因地制宜的农地流转制度。
