广州市城镇用地扩展及预测分析

了解城镇用地扩展相关规律,可以有效减缓建设用地对基本农田和重要生态环境用地的侵占,为未来土地科学合理地利用提供科学依据。本文对多期遥感影像数据进行解译,提取城镇用地信息,选取相关指标,运用指数分析法,对城镇用地扩展量化分析,从而探求其城镇用地扩展的相关规律。结果表明,广州市城镇用地扩展强度是有起伏的,城镇用地的重心向东北方向偏移,正南方向的城镇用地扩展稳定且较强,西南和正西方向较弱,其它方向则起伏较大。自然地理条件对城市扩展难易程度起宏观作用;经济对其有带动作用;交通设施则引导城镇用地扩展的方向;政策的作用是具有决定性的。通过总结广州市城镇用地扩展规律,选取相关因子进行广州市城镇用地未来变化预测模拟,并阐述了相关变化规律,并对未来城市用地扩展提供指导建议。

Choosing teaching as a career in urban public Catholic and Jewish schools by graduates of elite colleges

Recruitment, preparation, and retention of graduates of elite colleges is considered an innovative approach to improve teacher quality and promote change in the neediest schools. While the debate over the effectiveness of such programs is heavily focused on programs like Teach For America, this paper considers three teacher preparation programs located at elite colleges that combine alternative and traditional teacher preparation. This article argues that teachers who were trained at elite colleges and who chose teaching in urban public, urban Catholic, and Jewish schools tend to (a) conceptualize teaching around broad issues related to social justice, educational change, and community revitalization, arguing they joined teaching to improve society, and (b) seek leadership positions in their respective school sectors. These findings carry substantial policy implications in the areas of teacher recruitment, preparation, retention, and teacher quality.

Isolation and manipulation of living adherent cells by micromolded magnetic rafts

A new strategy for magnetically manipulating and isolating adherent cells with extremely high post-collection purity and viability is reported. Micromolded magnetic elements (termed microrafts) were fabricated in an array format and used as culture surfaces and carriers for living, adherent cells. A poly(styrene-co-acrylic acid) polymer containing well dispersed magnetic nanoparticles was developed for creating the microstructures by molding. Nanoparticles of γFe(2)O(3) at concentrations up to 1% wt.∕wt. could be used to fabricate microrafts that were optically transparent, highly magnetic, biocompatible, and minimally fluorescent. To prevent cellular uptake of nanoparticles from the magnetic polymer, a poly(styrene-co-acrylic acid) layer lacking γFe(2)O(3) nanoparticles was placed over the initial magnetic microraft layer to prevent cellular uptake of the γFe(2)O(3) during culture. The microraft surface geometry and physical properties were altered by varying the polymer concentration or layering different polymers during fabrication. Cells plated on the magnetic microrafts were visualized using standard imaging techniques including brightfield, epifluorescence, and confocal microscopy. Magnetic microrafts possessing cells of interest were dislodged from the array and efficiently collected with an external magnet. To demonstrate the feasibility of cell isolation using the magnetic microrafts, a mixed population of wild-type cells and cells stably transfected with a fluorescent protein was plated onto an array. Microrafts possessing single, fluorescent cells were released from the array and magnetically collected. A post-sorting single-cell cloning rate of 92% and a purity of 100% were attained.
