Drawing on fieldwork interviews and analysis of opposition social media posts, this article investigates how online forms of activism have been utilised by opposition groups during Bahrain's post-Arab Spring crackdown. Arguing that the antisystem opposition in particular has embraced ‘mediated mobilisation’ techniques, this article highlights the popularity of hybrid campaigns as drivers of online and offline activism. Contrasting the then-legal opposition society al-Wefaq with the banned, underground youth movement known as the February 14 Coalition, this article asserts that Bahrain's decentralised and anonymous antisystem opposition enjoys a structural advantage over regime-tolerated groups in their use of online activism. This article makes the case that mediated forms of mobilisation have fundamentally altered inter-opposition dynamics in post-Arab Spring Bahrain, and have strengthened the ability of antisystem groups such as the February 14 Coalition to challenge both the government and Bahrain's more established opposition societies. 相似文献

智慧社会时代,线上服务逐渐成为大众日常生活的重要组成,深刻影响城市居民的生活、工作及出行方式。论文基于手机信令数据等多源数据,分析了不同年龄段居民在居住区空间基础上的手机APP使用特征,进而总结了休闲娱乐、网络购物及日常服务三类APP的使用强度分布特征。结果表明:(1)休闲娱乐、网络购物与生活服务等成为居民高频使用APP类型,不同年龄段对APP类型存在偏好差异;(2)三类APP高使用强度集聚区与城市中心分布基本吻合,主要分布在商业集聚区、大型居住中心以及大学、景点等周边小区,遵循技术扩散假说,不符合效率假说;(3)不同年龄段使用强度城市分布热点存在差异,另保障房类型居住区其使用三类APP使用强度偏低。 相似文献

上海城市老年人日常购物活动空间研究 总被引:4,自引:0,他引:4
购物活动是老年人日常生活中主要的活动类型之一,对老年人日常购物空间的研究是理解老年人与其周围商业环境相互作用的关键,然而目前国内这方面研究才刚刚起步。本文以上海城市老年人日常活动问卷调查的第一手资料为基础,首先对数据进行汇总得出了上海城市老年人日常购物活动的发生频率、出行距离等总体特征。然后进一步细化,分别总结出各小区老年人的日常购物活动空间模式并进行对比分析,发现市中心老年人的日常购物活动空间比较紧凑,而郊区老年人的日常购物活动空间则相对分散。最后着重从上海市的商业空间及零售业态的变革、商业设施的可达性、老年人购物决策过程三个方面对这种差异性进行了解释。 相似文献

记忆是表现空间和地方重要的积极要素,在人与地方的关系建立中起着关键作用。文章以网络游记为数据源,基于游客记忆开展景观关注度研究,提出游客景点记忆衰减的概念模型。为景区发展、旅游消费提供理论指导,从旅游产业角度回应“美好生活需求”。研究发现:①10%的景点数量占据了94%的记忆份额;②能成为游客群体共同记忆的景点不多,黄山风景区有名字的299个景点中被游记记载的篇均次大于1的只有10个;③新世纪黄山风景区的山峰类景观点是游客记忆的核心,由游记高频词汇概括出的黄山“新五绝”为名峰、奇松、怪石、云海、日出;④景点关闭轮休导致其关注度下降,说明游览体验是游客景点记忆的重要影响因素。此外,黄山风景区的案例研究,印证了游客景观认知-记忆-表达过程中景观数量大幅衰减的规律。 相似文献

ABSTRACTThe photorealistic and geometrically accurate 3-dimensional representation of excavations, provided by image-based modeling, has the potential to transform the process of excavation documentation, making it easier to share observations with other researchers. Paradoxically, however, spatial representation lacks the ability to convey archaeological interpretations. By example of excavations in Alken Enge, Denmark, this paper explores how a web-based 3D platform is able to facilitate the collaborative exchange of 3D excavation content and how the integration of spatial and attribute data into one common event-based data model may be advantageous. This includes enhancing the semantic value of field-recorded 3D models by segmenting the geometry using various techniques, such as 3D projections and machine learning. Accordingly, the paper demonstrates a framework for interactive 3D models, which includes attributed classification based on segmented 3D content correlated with traditional raster, vector, and textual data, delivering a spatially integrated platform for collaborative research. 相似文献

Strong demand for GIS and burgeoning cohorts have encouraged the delivery of GIS teaching via online distance education models. This contribution reviews a brief foray (2012–2014) into this field by the Open University, deploying open source GIS software to enable students to perform practical science investigations online. The “Remote observation” topic spanned four science disciplines in 6 weeks – an ambitious remit within an innovative overarching module. Documenting the challenges and strategies involved, this paper uses forum usage and student feedback data to derive insights into the student experience and the pitfalls and pleasures of teaching GIS at a distance. 相似文献

作为智慧城市的重要组成部分,“新零售”得到蓬勃发展,提供当日配送服务的“新零售”深刻影响了城市生活服务的可获取性和时空可达性。本文以南京中心城区为例,运用两步移动搜索法、耦合协调度模型等方法,探究提供当日配送生鲜果蔬服务的店铺和传统生鲜果蔬实体店空间分布特征,分析线上和线下生鲜果蔬店铺的可达性及空间协调关系。研究发现,线上生活服务遵循技术扩散假说,强化了中心城区的生活服务集聚,同时线上生活服务集聚和可达性仍受实体地理空间约束;线上生活服务有悖于效率假说,对传统生活服务的空间分异具有加强作用,整体上没有提高生活服务的供给效率和空间公平性。研究结果可为新零售影响下城市生活服务设施的配置优化提供科学依据。 相似文献

基于旅游数字足迹的西安旅游流网络结构研究 总被引:5,自引:0,他引:5
Web2.0时代,游客通过互联网获取信息、购买产品,而且还会分享游记、照片。这些游客留在网络上的游记、照片和其它痕迹都含有时空信息,称为"数字足迹"。本文以西安为例,利用游记和照片获取旅游数字足迹,采用数据挖掘方式提取时空信息,并结合社会网络分析法,试图总结西安国内散客旅游流时间及网络结构特征。结果表明,数字足迹研究的时间规律和其它调研结论基本一致;旅游节点间分布不均衡;旅游网络密度低、结构分层明显。本文基于旅游数字足迹的研究,具有很强的可推广价值,可为等旅游管理研究提供新思路。 相似文献
