建筑工业化发展的多群体演化博弈与仿真研究

新型建筑工业化具有高质量、低消耗、可循环发展等特征，其推广已上升到国家战略层面。利用演化博弈方法，建立“政府-开发商-银行” 的三方动态演化博弈模型，进行各博弈主体策略的演化稳定性分析，并针对初始状态、奖惩力度、借贷风险和开发成本等对演化结果的影响进行动态仿真。在此基础上， 考虑开发商群体的网络拓扑特征对演化真实性的影响，引入复杂网络理论， 以无标度网络为载体描述开发商个体的连接偏好和决策机制，构建政府监管下的建筑工业化扩散模型，并通过仿真深入研究相关因素对扩散深度的影响作用，最后结合仿真结果给出相应对策建议。     

The beginning of immigrant settlement in the Helsinki metropolitan area and the role of social housing

Finland has experienced a rapid increase inimmigration since the beginning of the 1990s.Almost half of the foreign population isconcentrated in the metropolitan area of thecapital, Helsinki. The development andexplanations of their settlement patterns havenot yet been thoroughly studied. It ishypothesised in this study that social housingcan explain the settlement patterns. Indices ofdissimilarity were calculated to study thelevel and development of spatial segregation ofimmigrant groups in the Helsinki metropolitanarea in 1995–99, and the association betweenthe settlement patterns of immigrants andsocial housing was studied by regressionanalysis. Neighbourhood-level data were used.The results indicate that the Helsinkimetropolitan area has avoided extreme ethnicsegregation so far and that segregation isdecreasing. Especially immigrants from poorcountries are clearly associated with socialhousing in their settlement patterns, evenafter adjustment for socio-economic anddemographic differentiation. Also newconstruction of social housing seems to haveaffected the spatial distribution of thisgroup. Despite this dependence, the group isnot extremely segregated, which is probablybecause the social housing sector is nottotally marginalised.     

北京市危旧房改造的多目标分解模式

由于政府、居民、开发商之间复杂的博弈,北京市1990年提出的综合性危改目标遇到了很大的挑战,为解决这一问题,本文提出危旧房改造的目标分解模式,即建立一个以危改区域或危改项目为导向的危改目标实现框架,将北京市危旧房改造的多重目标进行分解,然后制定相应的分目标政策,建立相应的分目标制度,采取相应的分目标措施,最终从总体上实现危旧房改造的目标,主导目标的确定应遵循四个基本原则,最后提出几个政策建议。     

论社区服务产业化

社区经济作为一种优化的资源配置方式，利用社区服务为载体，将社区内互不相联的各种经济成份变为利益共同体，建立一种新的经济生产方式，从而带动社区乃至更广区域的经济发展。     

与时俱进 加快发展高职教育 推动我国工业化快速发展

当前,我国正在实施工业化的发展战略,要加快工业化的发展,必须大力发展和加强高等职业教育。在高等职业教育发展上,要实现从注重量到既注重量更注重质的转变;在培养方式上,要实现从只重技能到既重视技能又重视可持续发展能力培养的转变;在培养目标上,要实现从培养学生能力到培养复合型人才的转变。     

Pathway to health: Cluster-randomized trail to increase fruit and vegetable consumption among smokers in public housing.

Objectives: Examine the effectiveness of an intervention to increase fruits and vegetables (FV) consumption among smokers. Design: Cluster-randomized trial of 20 public housing developments; 10 randomly assigned to an FV intervention and 10 to a smoking cessation intervention. Main outcome measures: Usual (past 7 days) and past 30 days change in daily FV intake at 8 weeks and 6 months postbaseline. Results: Greater increases were seen in the FV group. At Week 8 and Month 6, the FV group had consumed 1.58 (p = .001) and 0.78 (p = .04), respectively, more daily FV servings in the past 7 days than the cessation group. At the same time points, the FV group had consumed 3.61 (p = .01) and 3.93 (p = .01), respectively, more FV servings in the past 30 days than the cessation group. Completing more motivational interviewing sessions (p = .02) and trying more recipes (p = .02) led to significantly greater increases at Month 6 among FV participants. Conclusions: Motivational interviewing counseling and lifestyle modification through trying out healthy recipes may be effective in helping a high-risk population increase their FV intake.
