城市低保制度在邵阳市区的实施情况调查——以对212户低保受助者的调查为例

为了解城市低保制度的实施情况,从中发现存在的问题以及解决这些问题的方法,相关研究机构组织了由大学生组成的调查员对邵阳市城区内多个社区两百余户低保受助者进行了走访调查。调查结果显示,低保制度能发挥居民最低生活保障的作用,是一项完成了基本任务的顶层设计;自谋生计是大部分低保受助者的主要经济来源,而低保制度不具备"养懒汉"的经济可能性。

Vicious advice: Analyzing the impact of TripAdvisor on the quality of restaurants as part of the cultural heritage of Venice

Venice is one of the most popular tourist destinations in the world. In Venice, as in other middle-sized heritage European cities, strong tourism pressure is trapping the city in a vicious circle that is eroding the quality of its tourism attractions. This development is related to the growing numbers of excursionists who lack the time to make informed decisions about the quality of goods. Consequently, suppliers reduce the quality of their offerings and instead focus on market share. Consumer-generated media (CGM) may help resist this development by providing excursionists with aggregated, up-to-date information on the quality of tourism offerings as perceived by customers. In this paper, we investigate the efficiency of TripAdvisor in helping tourists to make informed decisions and in increasing the popularity of restaurants offering a higher expected quality. Our findings suggest that, although TripAdvisor's algorithm is designed to reward quality, it does not adequately meet these goals.     

Making the ‘Invisible’ Visible: Redevelopment‐induced Displacement of Migrants in Shenzhen,China

Gentrification in China is intertwined with urban redevelopment, which causes the large‐scale displacement of rural–urban migrants from ‘villages in the city’ (ViCs). Because of the informality of ViCs, migrant renters have very insecure tenancy and during redevelopment they are treated as a negligible (‘invisible’) social group. As they are very difficult to locate after displacement, they are also literally invisible to researchers. To make the invisible visible, this study traced a sample of displaced migrants from Huangbeiling village in Shenzhen. The focus was on the displacement process and on identifying the consequences for the displaced. We found various forms of displacement during the redevelopment process. Nearby ViCs were prioritized by displaced migrants to minimize as much utility loss as possible. However, they generally suffer from decreased proximity, increased living costs, and the loss of social networks and job opportunities. Remarkably, some choose to return to the gentrifying village, enduring displacement in situ caused by increasing rents, drastic physical neighbourhood changes and declining liveability, in exchange for retaining their original social and economic networks. Large‐scale urban redevelopment is causing the rapid shrinkage of informal housing. Recognizing and addressing the housing needs of this impoverished social group is a matter of urgency.     

“西为中用·顺势利导”——生态雨水机埠 与合流制特点的老旧城区海绵改造

以常德市柏子园汇水片区为例，运用水力模型工 具，探讨在老城区现有末端生态雨水机埠情形下，通过优化设 置低影响开发(LID)设施和管网改造工程，从源头解决机埠合 流制溢流(CSO)污染的效果和可行性。根据棚户区较多、绿 地率少、土壤渗透性差、项目实施难度大等情况，进行项目方 案布置和LID措施选择；根据现状管网特征，进行近远期管网 改造方案和源头截流措施选择。采用典型年降雨数据进行连续 模拟，分析评估在老旧城区增设源头控制设施和中途管网改造 对既定末端机埠溢流水量及溢流频次的控制效果，并通过情景 方案比选，得出在现有土地使用条件下的最优海绵改造方案， 以期为类似合流制特点的区域提供参考和借鉴。     

Polycentric development in the Cape Town city-region: Empirical assessment and consideration of spatial policy implications

The concept of the ‘polycentric urban region’ has been popularised both as a theoretical concept for understanding regional urban systems in an era of reduced transport and communication costs, and as a normative policy objective in its own right. This paper explores its relevance to the rapidly urbanising Cape Town city-region. First, empirical evidence for the emergence of polycentric regional development patterns was considered. Shifts in relative settlements sizes (morphological polycentrism) over the period 1991–2011 were examined using population data, and patterns of inter-settlement interactions (functional polycentrism) were explored by analysing commuting information. Contrary to expectations, trends toward polycentric development were found to be weak. Second, the paper considers the relevance and value of polycentric development thinking for regional economic and spatial planning policy, concluding that there are insufficient grounds for policy intervention aimed at encouraging polycentric regional development or countering the dominance of Cape Town in the region.     

基于多级库存的电网运维物资安全库存优化配置研究

针对电力公司运维物资多级库存体系与安全库存配置现状,结合安全库存聚集效应,文章提出了周转库安全库存差异聚集策略。在综合考虑库存持有成本与普通、紧急配送成本的基础上,构建了安全库存优化配置模型。通过两类电网运维物资实际数据的分析,验证了差异聚集策略下成本低于全部聚集以及全部分散策略,可以为电力公司物资集约化、差异化、精益化管理以及仓库定额配置提供依据。

旅游发展对城市工业化的影响及其差异性研究——以58个旅游城市为例

文章构建了旅游业发展影响工业化的理论模型，并利用2000—2016年中国58个旅游城市面板数据和动态面板模型，从总体、专业化、规模和区域等多维度，分析检验了旅游业发展对城市工业化的影响及差异性。结果表明：无论是宏观层面，还是三种分类检验，旅游业发展对城市工业化都具有负向效应。当前，中国旅游城市存在一定的“旅游诅咒”效应，阻滞了其工业化深化；分专业化研究可知，旅游业发展对工业化的负向作用，由大到小依次为旅游高专业化、低专业化和半专业化城市；分规模研究发现，中型旅游城市的最显著，小型旅游城市次之，而大型旅游城市最不显著；分区域研究表明，中西部旅游城市的较突出，而东部旅游城市统计上并不显著。这为各个旅游城市采取有效措施及时防范和规避“旅游诅咒”效应和正确处理“旅游业+工业化”关系提供了参考依据。
