An Index of Invasiveness for the Measurement of Unifacial and Bifacial Retouch: A Theoretical,Experimental and Archaeological Verification

Archaeologists are increasingly in need of quantitative measures of stone artefact retouch. Existing techniques fail to provide a generic measure of retouching for all chipped stone artefacts. A fast and reliable index is proposed which measures retouch in terms of the invasiveness of flake scars on the surfaces of complete stone artefacts. Unlike other measures, the index of invasiveness is well suited to the analysis of bifacially worked artefacts such as bifacial points and bifaces. Experimental tests demonstrate a strong correlation between the index and measures of reduction based on diminishing flake weight and numbers of retouch blows. Inter-observer reliability is also demonstrated through the use of a blind test. Limitations of the method are discussed, although potential techniques for surmounting problems are identified. An archaeological application of the index demonstrates the utility of the method in the context of regional assemblage variability in northern Australia.

OPTIMAL HOUSING COST ESTIMATES FOR 177 U.S. METROPOLITAN AREAS

ABSTRACT This research tests the ability of six metropolitan‐level measures of housing costs to predict a benchmark housing cost measure based on Aten's area price level index. The first four measures are calculated with U.S. Census Data, the fifth is based on HUD Fair Market Rents, and the sixth is the housing portion of the ACCRA Index. In 25 large metropolitan areas, the fourth measure predicts 86 percent of the variation in the benchmark index in 1990 and 85 percent in 2000. The fifth measure performs nearly as well. The paper concludes both are promising measures of living costs.     

Determining Market Areas Captured by Competitive Facilities: A Continuous Equilibrium Modeling Approach

Many existing models concerning locations and market areas of competitive facilities assume that customers patronize a facility based on distance to that facility, or perhaps on a function of distances between the customer and the different facilities available. Customers are generally assumed to be located at certain discrete demand points in a two-dimensional space, or continuously distributed over a one-dimensional line segment. In this paper these assumptions are relaxed by employment of a continuum optimization model to characterize the equilibrium choice behavior of customers for a given set of competitive facilities over a heterogeneous two-dimensional space. Customers are assumed to be scattered continuously over the space and each customer is assumed to choose a facility based on both congested travel time to the facility and on the attributes of the facility. The model is formulated as a calculus of variations problem and its optimality conditions are shown to be equivalent to the spatial customer-choice equilibrium conditions. An efficient numerical method using finite element technique is proposed and illustrated with a numerical example.     

Identification of Employment Concentration Areas

This article presents a method to identify “Absolute and Relative Employment Concentration (AREC) areas” for a particular industry. Two novel characteristics of the method are that it simultaneously analyses AREC, and that it combines spatial concentration per area with the spatial concentration in neighbouring areas. The method is easy to understand and apply. It is developed to assist regional policy makers and corporate decision-makers with their investment decisions related to new infrastructure or plants. The identification of concentration areas also allows for analysing the performance of these areas in relation to characteristics such as infrastructure availability and the housing and labour market. This can yield new academic insights that are relevant for regional planners. An application of the newly developed method to five industries in a Dutch province subdivided into 502 areas illustrates the value of the method in comparison to other methods.     

河谷型城市居民生活空间质量特征及社会效应——以兰州市为例

城市居民高品质生活建设是推进新型城镇化、提升城市功能品质的有效途径。以兰州市为例，借助步行指数从安全性、健康性、便利性、舒适性和社会性五个维度构建城市生活空间质量指标体系，对兰州市河谷地区1221个居住小区生活空间质量及其产生的社会效应展开分析。结果表明：①兰州市城市综合生活空间质量整体偏低，呈“一主两次”的多核组团式空间结构，且具有“东高西低”的不均衡特征。②舒适性空间呈“高值—分散、低值—集中”；便利性空间呈多中心向外递减的趋势；健康性空间呈“中间高，两头低，高值偏东”格局；安全性空间呈河谷中心向外递减的趋势；社会性空间呈河谷中心高度集聚、边缘低值集中连片分布。③生活空间质量以中等质量生活空间、较低生活质量空间、低质量生活空间为主，较高生活质量次之，高质量生活空间最少。④兰州市生活空间质量分异产生了居民住房不平等与居住分异、资源配置失衡与空间剥夺、社会信任危机与社会隔离，以及居住区有机更新和空间重构等社会效应。     

ON THE STABILITY OF HOUSING SECTOR INTERACTION: EVIDENCE FROM 42 METROPOLITAN AREAS*

ABSTRACT. Residential vacancy chain models based on White's (1971) application of Markov chain theory are used to simulate flows of housing vacancies through a set of interdependent housing market sectors. Measures of housing sector interaction are derived from such models. Our purpose here is to address the issue of time stationarity raised by their use. U.S. census data are available to calibrate such models at two, and sometimes three, points in time. Data from 42 different SMSAs are used to generate 56 cross-temporal comparisons with interobservation periods ranging from three to eight years. Stability of interaction is addressed from two perspectives–the sectoral perspective and the areawide perspective. Results are mixed and depend upon which measure of interaction is used, which perspective is addressed, and the duration of the interobservation period. However, within limits, findings support continued use of vacancy chain models.     

长株潭地区聚落空间演化及其与耕地的空间关系研究

对2000年、2005年及2010年的遥感影像图进行解译,得到3个时期的土地利用分类图,运用景观指数法和空间分析法等方法,对长株潭地区聚落的空间演化特征及动因进行分析,并分析了聚落与耕地之间的空间关系。结果表明:长株潭地区聚落的面积、数量规模和分布密度加速扩大,集中分布在高程200 m以下;聚落空间演化的自然动因是低地平原指向,而社会动因是人口规模的变化;提出耕地与聚落面积比指数(K)概念,根据K值的大小可以将耕地与聚落的空间组合关系分为3类地区:耕地资源紧缺区、耕地资源平衡区、耕地资源盈余区;聚落与耕地的空间转移关系可以分为两大类:持续稳定型和动态变化型;长沙市周边耕地转为聚落的趋势十分明显;聚落空间扩张对耕地的影响存在一个空间临界点,城市化速度越快,临界点的位置距离聚落越远。     

城市公租房社区生活空间质量研究——以西安市为例

以城市社会生活空间质量观理念为研究框架,运用核密度、缓冲区分析等方法从社区物质环境以及居民对社区感知两个维度对城市公租房社区的生活空间质量进行评价。研究发现：西安市公租房社区空间布局较为偏远,集聚特征明显;除教育资源外,医院、商业以及游憩等资源均处于低可获性状态;社区居民对公租房社区房屋面积、房屋质量、物业管理、社区绿化等方面满意度较低,社区归属感及长期居住意愿不强。西安市公租房社区在社区资源可获性方面存在一定的空间剥夺现象,社区整体生活空间质量水平不高。     

辽宁省城市基本公共服务质量差异的时空分析

基于基本公共服务的内涵,从教育服务、文化服务、卫生服务、基础设施服务、社会保障服务、生态环境服务和信息服务7个方面构建了基本公共服务质量评价指标体系,运用熵值法对2003-2011年辽宁省城市基本公共服务质量进行综合测度,并以此为变量,利用差异系数和基尼系数对辽宁省各市基本公共服务质量差异的演变过程与空间格局进行定量分析。结果发现:辽宁省各市基本公共服务质量整体为上升的趋势,表现出较为明显的规模特征,沈阳市和大连市两极突出;2003-2011辽宁省城市基本公共服务质量区域差异总体扩大的基础上,呈现先扩大后缩小的演变趋势,且以文化服务、卫生服务和基础设施服务的差异为主;空间上,公共服务质量空间提升极化作用不断增强,表现为不断向"沈阳-大连、盘锦-本溪"的"十字"轴线紧靠。     

Campgrounds as service hubs for the marginally housed

The service hub concept is strongly associated with deprived areas of North American inner cities, where agglomerations of low‐cost housing and service providers form a space of survival for marginalised populations. In this paper, we contend that service hubs can take other forms, including as small‐scale sites of housing and service provision, informally networked across an urban region. We develop this argument with reference to suburban campgrounds in Auckland, New Zealand—a city experiencing a severe housing affordability crisis. Both individually and collectively, campgrounds enable vulnerable households, as well as tourists, to inhabit an increasingly exclusionary urban environment. Drawing on interviews with 24 resident campers and eight managers, we highlight the role of campgrounds in supporting residents through the provision of informal housing and on‐site services. This provision also benefits the facilities' owners and managers, by creating a year‐round rental income stream. We find that campgrounds are critically important for those whose lives are rendered precarious by the housing market.     

西方城市居住行为研究进展及其对中国的启示

改革开放40年以来,住房市场化转型使中国拥有了一个相对独特的住房制度环境,对城市空间结构、居民居住状况和民生福祉等各方面都产生了深远影响。中央政府明确强调需加快研究建立符合国情、适应市场规律的房地产基础性制度和长效机制,而这需要对城市居民微观居住行为进行深入研究。居住行为作为城市地理学的重要议题,近年来,相关研究虽不断涌现,但尚缺乏系统的理论梳理和实证研究总结。本文利用知识图谱可视化刻画了居住行为研究热点的演化,从居住迁移、住房产权获得、住房生涯三方面对西方相关研究进展和前沿进行评述,并进一步梳理了居住行为与城市空间的关系,以深化对城市居住空间分异机制的理解;在总结中西方差异的基础上,对中国现有实证研究进行了回顾;立足于中国国情和现有住房政策,分别从理论、内容、数据和方法三个方面对未来中国居住行为研究方向进行展望,旨在引起学术界对居住行为的关注,为推动中国居住行为研究理论构建、理解社会空间重构机制提供参考。     

西部地区县城居民住房消费的特点研究——以陕西省三原县、乾县等八县为例

县级是我国功能相对完备的基本单元,县城是城市经济和农村经济的结合部,又是工业经济与农业经济的交汇点,处于沟通上下、联络城乡的战略地位。同时县城也是我国推进城镇化战略的重要节点,西部县城居民数量占到西部城镇总人口的41%,因此,研究县城居民的住房消费特点十分必要。但县城居民的住房消费状况及特点研究在文献中并不多见。本文以笔者在陕西三原县城的调研数据为基础,并以在陕西其他七个县所作的三次调研数据作为补充修正。在上述数据基础上,测算出了西部县城住宅市场化指数,总结了居民住房现状,分析归纳出西部县城居民住房消费的特点。主要结论包括:西部县城很少有成规模的商品住宅小区、居民住宅分散、配套不完善、规划水平和物业管理水平很低,有实力的房地产公司尚未进入县城;县城的多层商品房售价在750元/平方左右,大多数居民接受低价位商品住宅,一般要求住房面积大于100平方米,对小区配套环境有一定要求,除水电基本配套外对市内配套设施的要求依次是暖气、太阳能热水器、天然气、网络。对开发商品牌有一定关注,对广告宣传比较相信。     

1992年以来我国城镇居民居住消费的变化趋势

1992年之后,我国明确了建立社会主义市场经济体制的目标,城镇住房制度改革取得了实质性突破,城镇居民居住消费发生了深刻变化。居民购房公平自由,私有住房的比重急剧攀升,住房设施日益完善,居住环境不断优化,居住开支迅猛增长,城镇居民居住水平获得了前所未有的提高。然而受不正确的思想观念的影响,在居民居住消费过程中,一些诸如住宅私有率过高、住宅面积过大、一房伴终身等严重脱离实际需要和基本国情的问题日益突出。     

大连市城市空间结构形成与演进机制

大连城市空间最初在沿海平原形成,然后圈层扩展,面积逐渐扩大,最后跨越形成组团发展模式。大连经历了从商贸港口城市到工业城市,再到综合性现代化城市的演变。城市内部空间结构则随城市功能定位和城市规划而不断调整。在影响城市空间结构的因素中,环境因素带来发展机遇的同时形成约束,政治因素主导了大连城市空间结构的演化过程,经济因素的影响越来越大,社会因素作用还不明显。     

基于模糊关系识别的多要素空间离散化方法——以江苏阜宁人口与经济分析为例

社会、经济要素的空间离散化是精细化县级主体功能区划的重要需求,本文提出了一种基于模糊关系识别的空间数据离散化方法。该方法利用广义权距离实现对专家知识与多系统分层要素的综合集成,并通过建立待离散化要素与其影响指标的模糊关系识别模型,获得空间离散化权重。以2009年江苏省阜宁县人口、GDP以及经济发展水平的空间离散化为例进行实例分析。结果显示,本文提出的空间离散化方法具有较好的准确性与可信度,可较好揭示各影响要素对待离散要素的空间影响。     

企业主义视角下大城市保障房建设的策略选择及其社会空间后果

城市企业主义是理解地方政府行为与城市空间变迁的重要政治经济视角,在中国推进经济全球化和住房市场化的背景下,企业化的地方政府,特别是大城市政府,在保障房的建设实践中往往采取偏向性的策略选择。本文着重讨论企业主义视角下大城市政府保障房建设的策略选择及其社会空间后果。研究发现,大城市政府主要通过实施保障房政策的异化和保障房住区的边远化策略,来履行其住房保障职责。然而,这种选择性策略带来的直接的社会空间后果是低收入群体的边缘化,具体表现为外来务工人员等在保障政策上的边缘化,以及保障房居民在社会空间上的边缘化。文章进一步指出,保障房应回归其保障本位,以满足低收入群体的真实需求。     

New immigrant settlement in a mid-sized city: a case study of housing barriers and coping strategies in Kelowna, British Columbia

The successful integration of immigrants into a new society is based on their attainment of several basic needs, including access to adequate, suitable and affordable housing. While this has long been a concern in Canadian cities, such as Vancouver, Toronto, and Montréal, it is also increasingly an issue in growing mid-sized cities such as Kelowna, in the interior of British Columbia. While Kelowna's real estate market is one of the most expensive in the country, there is little published data or literature on the housing experiences of immigrants in the city. This study examines the housing experiences and stresses of a small group of immigrants in Kelowna's rental housing market. This study uses data from five focus groups with 34 new immigrants and 20 interviews with key informants, conducted in Kelowna in summer 2008. The evidence indicates that for this group of immigrant newcomers, the housing search process in Kelowna's rental housing market met with significant barriers in locating affordable rental housing. Of these barriers, the most commonly cited were: (a) high housing costs; (b) lack of reliable housing information, including lack of access to organizations that provide housing help (government or not); and (c) prejudice by landlords based on the immigrants' ethnic and racial background.
This study points to the need for more comparative studies on the housing experiences of immigrants in mid-sized cities in Canada to better understand which groups of immigrants are more successful than others in finding affordable housing in these mid-sized cities, and why.

长期以来，我国租赁住房市场被严重边缘化，“十三五”规划明确提出建立租购并举的住房制度，彰显了让住房回归“居住属性”特征。住房租赁市场成为研究热点，而居民的租赁住房可支付能力是其关键。本文将保障性租赁住房与商品性租赁住房合为一体作为研究对象，从我国住房租赁市场的现状出发，客观评价不同人群的家庭可支配收入、最低非住房消费标准、住房补贴比例等指标，在此基础上定义人均租赁住房可支付能力指数，用于评估不同人群的可支付能力。结合目前的租赁住房市场的供给情况，运用GIS软件分析居民可支付能力的空间特征，分析北京市现有租赁住房与居民租房可支付能力匹配情况，对于合理制定多层次租赁住房市场政策具有参考意义。     

Environmental Quality and User Satisfaction in Mass Housing Areas: The Case of Istanbul

In a residence environment, housing and housing groups constitute a fundamental life space to meet the needs of the residents, to satisfy them, and to maintain the overall health of individuals and public. Various needs that appear due to the problems caused by housing and residence environment situated in a physical, psychological and socio-cultural environment together with their surroundings affect resident satisfaction and attitude, while directing the overall individual/family and public health, happiness and welfare. Most researchers argue about and try to determine the residents' needs related to their expectations of and satisfaction in housing and residence environment, within the framework of basic needs of human beings. In this study, in order to assess the factors that improve housing and environmental quality satisfaction, the concepts of housing and its environment, and the subject of housing and environmental quality satisfaction have been investigated; the conceptual model of housing and environmental quality satisfaction has been developed, which takes up the subject of user satisfaction in housing and environment quality as a whole; and the factors to increase the level of satisfaction in housing and environmental quality have been specified. A sum of 400 questionnaire inquiries has been made in planned mass housing areas in the Istanbul Metropolitan Area. Applying factor analysis to the data that have been gathered as a result of questionnaire inquiries, the following factors have been determined according to their order of importance to increase the level of user satisfaction in housing and environmental quality. The findings of this study show that, the elements influencing these factor groups include accessibility to various function areas in the inhabited housing area, environmental features of the housing, satisfaction in the various facilities in the inhabited environment, environmental security, neighbour relationships, and the appearance of the housing environment. A logistic regression model has been made to assess whether there are any differences among the factors influencing housing and environmental quality satisfaction for mass housing users on location choice (central districts and peripheral districts) at the metropolitan level.
