明末清初闽西的社会秩序重建——以泉上镇李氏家族为中心

明末清初,福建省宁化县泉上镇屡次遭受兵灾。泉上镇李氏家族通过修建土堡、山寨,倡建乡兵、保民会,以及家族精英的政治优势保障了家族和泉上地区在明清盗乱中的相对安定,同时李氏家族在明清动乱之际完成了宗族的收族活动。文章以此说明在明清交替过程中乡村社会的应对和社会秩序的重建,及在其中乡绅所扮演的角色。     

Early career teachers’ sense of professional agency in the classroom: associations with turnover intentions and perceived inadequacy in teacher–student interaction

Teachers’ capacity to learn intentionally and responsively in the classroom is particularly vulnerable during the first years in the profession. This study investigated the interrelations between early career teachers’ turnover intentions, perceived inadequacy in teacher–student interaction, and sense of professional agency in the classroom. The survey data were collected from 284 in-service teachers with not more than 5 years of experience and analysed by structural equation modelling (SEM). The results showed that the negative relation between turnover intentions and early career teachers’ sense of professional agency was completely mediated by perceived inadequacy in teacher–student interaction. The results indicate that experiences of insufficient abilities to solve pedagogically and socially challenging student situations have a crucial effect on early career teacher’s capacity for adaptive reflection and active transformation of instruction.     

Relating early childhood teachers’ working conditions and well-being to their turnover intentions

High turnover rates of early care and education teachers reduce the quality of education; unsatisfied teachers, suffering from stress or emotional exhaustion, are less equipped to promote children’s development and more likely to leave the classroom. We used data from a national survey of US early childhood educators (n?=?1129) to examine associations between teachers’ working conditions, well-being, and motivation with professional commitment and turnover intentions to move, leave, or remain. Multiple regression analyses revealed that more intrinsically motivated teachers were more likely to report intentions to move over leave, emotionally exhausted teachers were more likely to report intentions to leave, and lower teacher-reported working conditions predicted intentions to move or leave the field over staying. The results suggest that teachers’ well-being and perceived working conditions relate with their intentions to remain at their job or within the field and to their commitment to the profession.     

Child developmental impact of Pittsburgh’s Early Childhood Initiative (ECI) in high-risk communities: first-phase authentic evaluation research

The national debate surrounding the issue of school failure has renewed interest in the quality, efficacy, and outcomes of early childhood intervention programs that can promote early school success for children at developmental risk. Moreover, researchers and policymakers report the need to document developmentally-appropriate models for assessing and evaluating early childhood outcomes. We report on the first-phase results of Pittsburgh’s early childhood initiative (ECI). ECI is a privately-funded effort by a consortium composed of the business, corporate, foundation, and community sectors to implement high-quality early care and education options for children in high-risk neighborhoods. The overarching objective of ECI is to ensure early school success for high-risk children. Our Scaling Progress in Early Childhood Settings (SPECS) Evaluation Team implemented an authentic assessment and program evaluation strategy and an enhanced “constructed comparison group” statistical model to conduct longitudinal research on the child developmental impact of the ECI model. First-phase results on 155 high-risk children indicate that those who participated in high-quality ECI programs for the longest periods of time demonstrated patterns of progress that exceeded maturational expectations. Weekly collaborative consultation to teachers and caregivers by consultants about program quality using the National Association for the Education of Young Children (NAEYC) standards as “best practice” benchmarks seemed to be associated with initial enhanced child outcomes and the particular impact of the ECI model.     

Revisioning professionalism from the periphery

Abstract

The issue of who should be included and recognised as professionals in the early childhood education and care (ECEC) service system is both contested and pressing in the current policy climate. At stake is a high-quality early childhood care and education service system that is both responsive and appropriate to the constituency it serves. A review of the history of ECEC professionalism reveals complex entanglements and debates regarding professional belonging. Services that deliver education and care to children and families living in high poverty contexts are often excluded from ECEC professionalism debates. Drawing on notions of rationality, emotionality and criticality presented in recent accounts of ECEC professionalism, we use data collected from interviews with service providers delivering services to children and families living in high poverty contexts in Australia to develop an account of criticality that is pertinent to current funding and policy contexts. We argue that these service providers’ perspectives about their own professionalism have much to offer broader debates.     

Beginning reading strategies in children experiencing contrasting teaching methods

Two groups of 4.5–5.5 year old children in their first year at school were examined; one taught by a whole word teaching method and one taught by a mixed whole word and phonological teaching method. The children were given a test to investigate their reading of normal words. The results of this test were subjected to a detailed error analysis and the two groups were examined in order to see if there were differences in the reading strategies they used. No evidence was found counter to the assumption that reading begins with a logographic stage. However, it was found that teaching method was having a significant impact on the reading strategies which the children adopted. In addition it was found that a number of children from the whole school appeared to exhibit letter by letter reading. This suggests that letter by letter dyslexia might in part be an extreme form of a strategy used by normal readers.

燕山构造带滦平早白垩世盆地沉积过程和演化

滦平盆地是燕山构造带内一个具有代表性的早白垩世伸展盆地.对盆地内沉积岩相和相组合的详细分析结果显示,盆地内部发育不同的沉积相带并显示明显的空间变化.盆地北部和西部边缘以冲积扇砾岩和扇三角洲砂岩、砾岩沉积为主,盆地中心为湖泊细粒沉积.河流相砂岩和砾岩主要分布于盆地的东南部.古流向和物源恢复结果证明,盆地沉积物主体来自于北部和西部老变质岩基底,仅少部分沉积物来自盆地的东南缘.盆地构造沉降和沉积充填过程主要受北缘和西缘张性断层的控制,断层下盘基底岩石的抬升与盆地边界正断层活动相关,从而成为盆地主要的物源区.滦平盆地的演化可划分为三个阶段：即早期火山喷发阶段、中期强烈断陷阶段和晚期填平阶段.滦平盆地代表了早白垩世燕山构造带其它同类盆地的发展过程,它们皆以小型独立的盆地发育为特征.     

清末民初云南地方法治的社会政治环境考察——以中央与地方关系为视角

在中央新政改革和云南地方自治逐步推进的特殊背景下,清末民初的云南地方法治运行及其条件十分复杂,它以消除领事裁判权的存在及其割裂司法权的威胁等为动因,是政治、经济、文化等多种因素相互交织影响,国家、地方官员、地方精英等各方力量彼此博弈与妥协的动态过程。其正向意义是奠定了地方自治的前提,为宪政发展作了准备;其负面效应则是它在一定程度上造成了法治力量在地方的客观性弥散化。
