对建设昆河经济走廊的认识与思考

“昆河经济走廊”概念的提出,是中越两国政府加强经贸合作,促进相关地区区域经济合作,实现优势互补的重大战略举措,为区域内各相关地区提供了重大的发展机遇。昆河经济走廊的建设有较为有利的条件,走廊建设要以区域内的城市群和产业群为依托,优化区域分工和重点产业布局,建立多领域、多层次的合作开发机制。     

7～16岁学生解决“汉诺塔”问题的心理测试

应用计算机多媒体技术,虚拟问题情境,设计了"汉诺塔"动态心理测试软件。对来自两个学校的451名7～16岁学生进行了实测,观察到一些传统纸笔测验不能控制的心理信息流动过程,初步探讨了各年龄段学生解决"汉诺塔"问题能力的发展趋势及特征。结果表明,所设计的"汉诺塔"软件可作为测试、评价学生解决问题能力的一种心理测试工具,尤其适合于14岁以下学生。

Unofficial Hanoians: Migration,Native Place and Urban Citizenship in Vietnam

Independent migration to Hanoi has surged dramatically over two decades of deepening market reforms, blurring the distinctions between urban and rural lives once maintained so carefully by the Communist Party of Vietnam. However many urban migrants face ongoing legal and social obstacles in Hanoi, tied to an outmoded system of household registration (ho khau), and widespread anxieties about the ‘floating population’ threatening to overwhelm the city. This article shows how one group of ‘unofficial Hanoians’—migrant motorbike taxi drivers from Nam Dinh Province—navigate a system of differentiated urban citizenship by forging communities and mutual assistance networks around shared ‘native places’ (que huong) to find employment, housing and social support in the city. It also reveals how Hanoi's marginal urban spaces—home to entrenched migrant communities of ambiguous legality—emerge as key arenas in the negotiation of Vietnamese citizenship, forcing national leaders, city officials, landlords and residents to grapple with questions of free movement and the rights of rural citizens to transgress urban space.
