In this paper, we outline a framework to study what we have termed “Predatory Cities”, using the artificial offshore island of The Pearl in Qatar as a case study. By focusing on the nexus between urbanisation and resources, we will argue that the master-planning of new cities in the booming global South implies both the access and cheap exploitation of a set of, on the one hand, intangible and, on the other hand, tangible resources that exceed the traditional boundaries. Our point of departure is that the cheap appropriation and exploitation of alien architecture images and resource networks for the making of new, master-planned cities has become a necessary, but highly unsustainable, strategy to survive an increasingly competitive global offering of new destinations.  相似文献

Predatory lending and abusive practices arose as a serious danger by increasing the threat of foreclosure and bankruptcy and decreasing the equity accumulated in a housing unit, reducing many of the economic benefits of homeownership. This article describes the characteristics of areas who likely suffered from abusive mortgage lending using Census data, Home Mortgage Disclosure Act data, and publicly recorded mortgage data. A proxy measure of predatory lending is developed based on the loan-to-value (LTV) ratio and state anti-predatory lending regulations, and represents excessively leveraged properties. Discriminant analysis is used to distinguish between areas with these highly leveraged properties and other parts of the City of Philadelphia. The residuals are mapped to evaluate the spatial dimension of the discriminant models across the city. This examination of demographic and socioeconomic characteristics informs efforts to mitigate the consequences and prevent future occurrences of both predatory lending and other manifestations of inequality by viewing it as a spatial and neighborhood phenomenon.  相似文献

以P2P网贷平台为例,探究中国互联网金融企业生存的时空差异及其影响因素。结果表明:① P2P网贷平台寿命的城市差异较大,平台上线和退出主要集中在深圳、上海、北京及其周边城市。② 平台经验和较高的城市经济水平有利于平台存续和合规发展,但城市内部的风险传染值得关注;鼓励性政策有利于合规平台生存,但也会提升问题平台的非正常退出风险;较晚的进入时间会使平台生存受限。③ 集聚经济是影响P2P网贷平台生存的主要机制,企业的存续与企业进入市场的时空选择紧密相关。  相似文献

Koura, Paranephrops planifrons, were found up to 1260 m a.s.l. in a subalpine area of Tonga‐riro National Park in May and July 1978. Their habitat is described briefly, and possible factors limiting the distribution and abundance of high altitude populations of freshwater crayfish are listed. It is suggested that all mountains may not necessarily form absolute zoogeographic barriers to koura; the kind of mountain and the ecological milieu may be more important.  相似文献

论鄂尔多斯历史农业   总被引:4,自引:1,他引:3

鄂尔多斯是古"河套人"的故乡,是中国北方各民族最早活动的历史舞台。这里以其悠久的历史、丰富的物产、灿烂的草原文化闻名遐迩。特殊的草原自然环境,吸引了大漠南北众多游牧民族和部落的人民在这里劳动、生息、繁衍,与中原王朝分庭抗礼;濒临中原腹地的战略位置和宜耕宜牧的资源条件,警示着中原王朝不惜国力加强对这一地区的控制。鄂尔多斯地处黄河流域,是中国原始农业的起源和发展中心之一。中原王朝控制之下,以农业著称,游牧民族占据时,则以畜牧业见长。亦耕亦牧,形成了农牧结合的经济结构,为多民族地区的形成和社会发展做出了历史性的贡献。然而,掠夺性的经营,以牺牲自然环境为代价,加速了该地区的沙漠化。今天,实行农牧业产业化,退耕还林还草,休牧轮牧,是建设山川秀美的鄂尔多斯的必由之路。  相似文献

The giant trevally Caranx ignobilis (Forsskål) is an important apex predatory fish typically associated with coral reef communities. It is prized in recreational and commercial fisheries, yet little is known about its aggregation dynamics and susceptibility to fishing pressure. This study reports on a previously undocumented aggregation of mature giant trevally observed over a period of eight years (2010–2017) at Ponta do Ouro Partial Marine Reserve in southern Mozambique. The aggregation is one of the few recorded for this carangid in the western Indian Ocean and represents the first subtropical aggregation of giant trevally. The aggregation is also the largest recorded for this species, with up to 2 413 individuals representing an estimated biomass of approximately 30 tonnes. The size and predictability of this annual aggregation make it vulnerable to overexploitation and point towards the need for an appropriate conservation management strategy.  相似文献
