Learning mobility: high-school exchange programs as a part of transnational mobility†

Long-term high-school exchange is a popular way to go abroad for German youth (2.5% of 16-year-olds go abroad for 6–12 months). The ongoing research project is dealing with the long-term impact of high-school exchange programs on further mobility of the participants. Using an online survey among 3000 former exchange students and 30 qualitative focus interviews, it is shown that mobility reproduces itself. Six years after the exchange, about 80% of the respondents have been abroad again for a period of longer than six weeks. This is seen as part of a normalization of transnational social practices.     

加拿大二线城市华人新移民经济融合研究——“三重玻璃效应”与移民向下层社会流动

论文对加拿大二线城市卡尔加里和爱德蒙顿华人新移民的主要特点、移民动机和融合过程中的主要障碍进行了分析,探讨了新移民在加拿大向下层社会流动的问题。研究显示,新移民在经济融合过程中遭遇多方面的障碍,尤其在就业和语言方面。他们在移民加拿大之后,经历了去技能化和以前的学历和工作经验贬值,促使他们向下层社会流动,而这种状况反过来又阻碍了他们的融合进程。华人新移民的负面经历可以归因于由玻璃大门、玻璃房门和玻璃天花板构成的"三重玻璃效应"。加拿大政府应采纳融合框架政策,除承认移民的流动自由外,还要保证他们能享有与其他加拿大人一样同等的公民权益。     

毛泽东与中国科学技术的自主研发

毛泽东将科学技术视为革命者完成自身历史使命的重要工具,他洞见先进技术在后发国家追赶发达国家中的作用,将大力发展科学技术视为国家的重要职能,在西方国家封锁禁运、苏联毁约的困境下,千方百计引进先进科技并努力促进自主研发,果断地发展高科技产业,提高中华民族的国际地位,为中国进一步发展打下了基础。回顾毛泽东与中国科学技术自主研发的历程,有助于我们深刻认识和实践新形势下中共中央、国务院做出的建设创新型国家的重大战略决策。     

Piot,Personhood, Place and Mobility in Lihir,Papua New Guinea

ABSTRACT This paper is an exploration of the nature of personhood through the medium of the concept of piot in the Lihir islands, Papua New Guinea. Piot is an embodied experience in response to the movement of others in space. When people leave or arrive at a place and spend the night, others in the area feel unwell. Piot is thus one aspect of the relations between persons. I suggest that ideas of relational personhood are inadequate to fully comprehend piot, and, following LiPuma (1998) and Clay (1986) rather than Strathern (1988), argue that persons in Lihir are more than just relational beings who always act with others in mind. Piot is predicated on the dual themes of fixed sociality and mobility that are important in Lihir as elsewhere in Melanesia (cf Eves 1998; Patterson 2002). Through piot, persons comment on and sanction the movement of others, yet this mobility still occurs.     

基于腾讯迁徙数据的中国“春运”城市间人口流动空间格局

“腾讯迁徙”大数据基于位置服务，实时、动态、完整、系统地描述了用户日常出行活动的轨迹。通过采集“腾讯迁徙”数据平台中2018年春运期间中国346个地级及以上城市之间的逐日人口流动数据，分“节前、节中、节后”3个时间段，利用复杂网络分析方法，从人口流动的集散层级、集散体系分层集聚特征、人口流动空间格局、网络空间特征等角度分析各时间段城市间的人口流动特征与空间格局。结果表明，腾讯迁徙大数据直观地揭示了春运期间中国城市间人口流动空间格局，3个时段人口的净流入均呈现十字形骨架支撑的菱形分布，人流集散中心主要集中在京津冀、长三角、珠三角和成渝4大城市群，与城市等级有较强的一致性。人口流动集散体系呈明显的分层集聚，城市行政级别的高低与人口流动影响力存在一定的正相关关系，大部分城市人口流动处于“相对平衡”状态。人口流动网络呈现东密西疏的分布特征和东部并联、西部串联的网络关联特征。人口流动网络局部具有较明显的“社区”结构特征，聚为3个大区级、5个跨区域级和1个地区级社区。     

Embodied bicycle commuters in a car world

As an initiative to increase cycling, bike to work (BTW) events emphasize a pragmatic approach in which people learn through sensory experience. Pragmatism contends that the lived experience of the commuter within fluid geographies of social and physical conditions informs commuting knowledge and behavior. I researched how bicyclists participate in the 2012 BTW event in Lake Tahoe (USA) and how these experiences facilitate the process of becoming bicycle commuters. My study included participant observations, interviews, video observations, and route mapping. I analyzed this data with thematic and narrative analyses. I find that the BTW event illuminates bicycling, a normally invisible practice in a car world, and creates temporary bicycle-friendly spaces that provide the embodied experience and knowledge of bicycle commuting within context. Through this lived experience, participants can break free from unconscious car-based patterns and become embodied bicycle commuters who engage in active renegotiations of their commuting practices.     

Student geographies and homemaking: personal belonging(s) and identities

Studies of the ‘geographies of students’ have become increasingly prevalent across the social sciences and are particularly concerned with the predilection for young UK University undergraduates to be mobile in their institutional choice. A more recent focus within this work has been upon student identities, with attention given to how the spaces to which students move and in which they settle can have both positive and negative consequences for the evolution of the student identity, and how such identities are often framed within the context of social activities; learning environments; friendship networks; or other sociocultural factors. This paper contributes to these discussions by considering the role of student accommodation – a site which often remains on the periphery of discussions of student identities – in offering students opportunities to construct, adapt and manage their student identities. This adds to the important contemporary geographies of student accommodation, which are currently debating, among others, purpose-built student accommodation and the broad housing ‘careers’ and strategies of students. In contrast, this paper explores the micro-geographies of student accommodation (and more specifically, the bedroom) to highlight its value in providing young, mobile students with an anchor within which they can draw together their learner, social and domestic dispositions into one geographical location.     

Development of a systems model to visualise the complexity of children's independent mobility

Substantial changes to the built environment, urbanisation patterns, and societal norms have contributed to limiting children's opportunities for being independently mobile. Several linear causal pathway models have been developed to understand the influences on children's independent mobility; however feedback loops between and within the various levels of influence cannot be modelled using such an approach. The purpose of this paper is to refine the interrelationships of factors related to children's independent mobility, taking into account earlier models, broader contextual factors, recent children's geographies literature, and feedback loops. Systems model components were informed by attributes known to influence children's independent mobility, related qualitative findings, and the development of a framework that could lend itself to multilevel modelling approaches. This systems model may provide a useful structure for identifying how best to develop and monitor interventions to halt the declining rates of children's independent mobility.     

Spaces of the street: Socio-spatial mobility and exclusion of youth in Recife

The ‘street’ and ‘youth’ have long been issues of social concern and the subject of research both in Brazil and elsewhere. The perception and experiences of youth in relation to the street, however, and the corresponding gender and class relations which permeate these, remain an under-researched topic. Drawing on fieldwork conducted in low- and middle-income neighbourhoods in Recife, this paper shows how the street consists of different spaces and how the youth experience corresponding layers of socio-spatial exclusions and inclusions which vary over time.
