大数据在智慧城市研究与规划中的合理运用

经济实力的增长使得我国的城市发展迈入了新的发展台阶,传统的城市发展和规划方式显然难以与现代化发展方向相一致,信息技术不断发展的过程中,越来越多的城市开始投入了智慧城市建设。但智慧城市发展中,对于技术的依赖性相对较高,不论是智慧交通、智慧社区还是智慧医疗,都需要有大数据技术的支持和保障,以构建城市崭新的发展路径。基于此,本文详细分析了关于智慧城市规划中的大数据技术应用,有利于加快智慧城市发展步伐。     

Sense of belonging,international migrants’ spending,and implications for their subjective well-being

A lack of a sense of belonging in the host country has become one of the most common challenges facing international migrants in today's sociopolitical environment. Our two online experiments with 881 international migrant workers in the United States jointly demonstrate that, to cope with their lack of a sense of belonging in the host country, international migrants may spend money suboptimally: more on material purchases but less on experiential and prosocial purchases. More importantly, our studies suggest that prosocial purchases are more effective than experiential purchases in increasing international migrants’ subjective well-being. This is because prosocial purchases can lead to both relatedness need satisfaction and beneficence, with each independently contributing to international migrants’ subjective well-being. Our research suggests that public policymakers should address the social exclusion international migrants experience when moving to a new country because it can have a negative impact on their subjective well-being. Our research further suggests that one way to mitigate social exclusion is to encourage international migrants to spend money on others rather than themselves.     

Optimal zoning of managerial duopoly

This paper investigates optimal zoning of two managerial firms in an unconstrained linear city. Comparing with the case in which firms are not managerial type, the strategic delegation increases the incentives of one firm to locate farther from the rival. Then, a welfare function is introduced to highlight zoning regulation as an influential competition policy tool. Depending on the regulator's objective function and the timing of location choice, we provide a new mechanism that allows the regulator to attain the optimal locations of managerial firms and can lead to strong or weak competition.

一种最小误码率约束的动态地理协作路由算法

为了提高无线多跳通信的可靠性，提出一种联合物理层和网络层设计的动态地理协作路由(DGCR)算法，推导计算了单个协作单元协作中继节点的选择区域，在该区域内选择的协作中继节点可以满足误码率要求。最佳中继节点的位置会根据实际协作中继节点的位置和目的节点的位置动态选取。仿真计算表明，该算法相比非协作路由算法和传统地理协作路由算法具有更好的误码率性能，更适用于多径条件下的应用。
