清代河西走廊的水资源分配制度——黑河、石羊河流域水利制度的个案考察

水利纷争是清代河西走廊主要的社会问题之一。为解决水利纷争,建立了不同层次的分水制度,即流域内上下游各县之间的一次分水,一县内各渠坝之间的二次分水,一渠坝内部各使水利户之间的三次分水,力图使各县之间、各渠坝、各农户之间平均用水。分水的技术方法是确定水期、水额。分水的制度原则有二:一是公平原则,即按地理远近;二是效率原则,即按修渠人夫使水、记亩均水和按粮均水,记亩均水多实行于水源丰沛地区,按粮均水多实行于水源短缺地区。分水制度在一定程度上缓解了水利纷争。地方各级政府发挥了调节平均用水的作用。

Mitigating the Effects of Poverty and Crime: the Long-Term Effects of an Early Intervention Programme for Children who were Developmentally Delayed and Prenatally Exposed to Cocaine

This study explores the long-term impact on participation in the Linda Ray Intervention Program (LRIP) for children (n = 54) who were developmentally delayed and prenatally exposed to cocaine. By identifying a group of programme graduates from a high crime/high poverty neighbourhood in Miami-Dade County using ArcGIS 10.2 software, a quasi-experimental design was used to compare children living in this area who participated in the centre-based modality (5 h a day; 5 days a week) to children living in this area who participated in the home-based modality (3 h per week) on their Florida Comprehensive Assessment Test (FCAT) reading and math scale scores in public school. The children who participated in the centre-based modality reported stronger outcomes in both math and reading FCAT scale scores at the p < .05 level and also out-performed their school-age peers on both math and reading FCAT scores at the p < .05 level.

Core competencies and high leverage practices of the beginning teacher: a synthesis of the literature

Teacher competency frameworks comprise a number of competencies that enable a teacher to develop effective teaching practices. However, their conception, value, use and recognition vary widely. Equally, assessment and measurement of such competencies differ across contexts. More recently, a body of research has emerged which focuses the lens of teacher preparation on the inclusion of high leverage practices. The focus of this study is to report a synthesis of the literature pertaining to the ‘core competencies’ and ‘high leverage practices’ selected for inclusion in teacher preparation. A systematic review of the literature was conducted in order to synthesis available evidence. Results are presented in two sections; competency-based approaches; and high leverage practice approaches in teacher preparation. Findings are discussed from the perspective of epistemological and methodological questions emerging from the research and the implications for teacher preparation.
