基于手机信令数据的长春市活动空间特征与社区分异研究

居民时空行为成为透视城市空间的重要视角,本文基于手机信令数据研究长春市活动空间及其社区分异,轮廓性的揭示居住空间、就业空间和消费休闲空间的分布规律,从人地互动的过程与格局的视角认识城市空间。研究发现,居住活动对中心城区依赖明显高于就业和消费休闲活动,就业活动呈现多中心连片发展格局,近郊的欧亚卖场和郊区的净月潭成为人们消费休闲活动的重要选择。就业-居住距离和消费休闲-居住距离的社区分异显著,折射出三类活动空间关系复杂,由此感知城市生活空间质量和社会空间结构。通过对社区分异的空间聚类分析明晰各地域自身问题,从而有针对性的对长春的空间调整优化和居民行为引导提出建议,构建和谐宜居的城市空间。     

New Philadelphia: using augmented reality to interpret slavery and reconstruction era historical sites

Does a historical site lose its significance or become less worthy of interpretation if there are no surviving buildings? Can technology help present the stories of disadvantaged and disenfranchised groups whose heritage lacks well-preserved architecture or material culture? The emerging technology of augmented reality (AR) offers new ways of designing and shaping the public’s experience when visiting landmarks by enabling an unprecedented means to combine 3D historical visualization with historical landmarks. This especially applies to underrepresented groups whose heritages have not been well served by traditional modes of preservation and interpretation due to a variety of factors. These range from disadvantages relating to material culture to a greater emphasis on intangible heritage which have placed them outside the bounds of what archaeologist Laurajane Smith calls authorised heritage discourse. A project at the New Philadelphia National Historic Landmark, located in Pike County Illinois, seeks to address these issues through AR. The technology, while offering opportunities for historical interpretation, poses challenges in terms of designing AR systems that coordinate content presentation with specific locations as well as developing virtual historical content with varying levels of source materials.     

Migration,the Urban Periphery,and the Politics of Migrant Lives

This paper explores the politics of migration through a focus on labor migration regimes and the urban lives of migrants in the Seoul Metropolitan Region of South Korea. In particular, it draws attention to the ways in which migrant lives highlight the limits of the contemporary emphasis on control in migration management regimes. The paper contends that while migration management certainly reworks the socio‐legal status of migrants, the desire for control is often displaced in the everyday presence and practices of migrants as urban residents. In order to develop this argument I focus on the notion of the urban periphery as a spatio‐temporal configuration that manifests marginalization but is also potentially generative, innovative and destabilizing. The paper proceeds by exploring three dimensions of the periphery: (1) the mobile commons that emerges in everyday life; (2) the process of becoming undocumented and the subversion of control; and (3) the tactics of recognition that challenge the peripheral location of migrants. In each case the focus on the urban periphery draws attention to the importance of visibility and invisibility in migration, to the uneven spatio‐temporal configuration of migrant lives in the city, and to the ways in which migrant desires constitute a politics that exceeds what is normatively expected of them.     

移动信息技术影响下的城市空间结构研究进展

手机用户、手机网民规模的不断增大意味着移动信息技术的出现和应用带来了信息革命的第二阶段。移动信息技术开始赋予了空间以新的内涵,其影响下的空间结构成为地理学研究的主要内容之一。本文重点梳理西方学者近些年来关于移动信息技术及其影响下的城市研究范式、研究内容变化的最新成果,以期了解最近的学术动态,并为国内相关研究提供一定借鉴。     

Fears and aspirations

Very little study has been done of the role of US Intelligence in the South Pacific command in the Second World War. Collection of information on the civilian population concentrated mainly on settlers, sojourners and migrant labour, but military personnel also come under scrutiny. US intelligence collecting was at its most intense in New Caledonia, a major base for the US forces and a country rated as highly strategic by the Allies, especially in the early phases of the war with Japan. Because of the Vichy‐Free French divide from 1940 on, the US was especially wary of possible subversion of the war effort there, but its purview also took in the Asiatic and Melanesian population though the latter, as in the Southwest command, were not considered a major threat. Even so, the magnitude and detail of the intelligence carried out suggests that post‐war political considerations were never far from the US government's wider concerns and aspirations.     

Student perceptions of iPads as mobile learning devices for fieldwork

This paper reports findings from six field courses about student's perceptions of iPads as mobile learning devices for fieldwork. Data were collected through surveys and focus groups. The key findings suggest that the multi-tool nature of the iPads and their portability were the main strengths. Students had some concerns over the safety of the iPads in adverse weather and rugged environments, though most of these concerns were eliminated after using the devices with protective cases. Reduced connectivity was found to be one of the main challenges for mobile learning. Finally, students and practitioners views of why they used the mobile devices for fieldwork did not align.     

The Ethics Minefield: Issues of responsibility in learning and research

Google Glass was deployed in an Urban Studies field course to gather videographic data for team-based student research projects. We evaluate the potential for wearable computing technology such as Glass, in combination with other mobile computing devices, to enhance reflexive research skills, and videography in particular, during field research. The utility as well as the limitations of Google Glass are discussed, including its actual and potential application for teaching and data gathering purposes in the field. As such, this article constitutes one of the first instances of evaluating Google Glass as a social science research tool.     

Mobile Media as New Forms of Spatialization

Abstract

The physical space has historically served as an important support for human expression. However, the production of location-based information has been consciously used as means of social control by the hegemonic power, which decides what can be publicly displayed, and what should be hidden. With the development of mobile media, space has gained new dimensions, resulting in a sort of hybrid space where digital information overlays the physical space revealing what was previous unknown about a place. As mobile devices become increasingly present in our society, they should be understood as a social interface to our experience of space, serving not only as means to consume information, but also tools for communication. This paper discuss the current mobile media practices, such as mapping, urban electronic annotations, location-based mobile games, and smart mobs, which creates opportunities for new forms of human expression, reappropriations of space, and contestation of hegemonic power.     

The Heritage of 30 Years of Mobile Communications in the UK

The first mobile phone networks were launched in the UK in 1985. In the 30 years that have elapsed since then, the mobile phone has evolved from an expensive device owned by the few to a mass-market smartphone that is now regarded as an essential part of modern-day life. Behind the scenes, the mobile networks have undergone four major technology evolutions that have transformed their functionality from providing a basic telephone service to offering very high-speed connectivity for data applications. Yet, much of the heritage of this relatively young but transformational mobile technology is poorly documented and in great danger of being completely lost. Each new generation of mobile network replaces and ultimately erases the evidence of its predecessor. Equally, manufacturers are so focused on the release of their next handset that this leaves little scope or motivation for preserving and recording older models. The perception remains that the mobile phone is a new and young technology which is still considered by many to be a recent phenomenon. This results in a very casual attitude to the preservation of cellular mobile communications heritage, hence raising the significant risk that no suitable historical records will be available for future generations. This paper therefore begins to address this deficit by examining, through a UK perspective, two key but highly visible parts of the mobile phone story, namely, the cellular radio site installations that adorn roadsides, rooftops and hillsides and the mobile phones themselves as important historical artefacts.
