英国工业革命期间的社会立法     

赵虹 《云南师范大学学报(哲学社会科学版)》2002,34(6):38-42

在英国步入“福利国家”的历史进程中,各项社会立法的提出、确立、不断完善是其主要途径之一。其中,在英国工业革命期间的几项社会立法无疑处于这一社会立法轨迹中的起始阶段,有其渊源关系。其他位和作用应予以肯定。  相似文献   

流动家庭学前儿童早期阅读教育存在的问题及对策——以上海松江区为例     

张晓茹  卢清 《幼儿教育》2011,(30)

早期阅读教育是幼儿语言教育的重要组成部分。流动家庭学前儿童早期阅读教育无论在理论层面还是实践层面受关注的程度远远不够。流动家庭学前儿童早期阅读教育存在意识淡薄,目标单一,内容狭窄,方式简单、机械,环境不容乐观等问题。流动家庭学前儿童的早期阅读教育可以通过提高家长对早期阅读教育的认识以及引导孩子合理收看电视节目、建立流动图书馆等策略加以改善。  相似文献

A Study of Infant Developmental Outcome with a Sample of Korean Working Mothers of Infants in Poverty: Implications for Early Intervention Program     

So-Jung Seo 《Early Childhood Education Journal》2006,33(4):253-260

Using a sample of 42 Korean mothers whose infants are cared for by someone at non-maternal child care facilities, this study first examined both main effects and interaction effects between maternal knowledge of infant development and maternal self-efficacy on parenting behavior. Second, the combined effects of variables of interest in this study including maternal knowledge of infant development, maternal self-efficacy, and parenting behavior on the child developmental outcome were investigated. Significant relationships between maternal knowledge of infant development and parenting behavior and child development outcome were detected. Only main effects of maternal knowledge of infant development were detected. Furthermore, maternal knowledge of infant development was the only significant predictor of infant developmental outcome. Research implications were discussed both on the continuum of findings from previous studies with Western samples and in terms of provision of effective early intervention programs for this targeted population.  相似文献   

What successful black South African students consider as factors of their success     

Pentecost M. Nkhoma 《Educational Studies in Mathematics》2002,50(1):103-113

Black South African students have a poor success rate in school leaving mathematics examinations. Attempts have been made to shift teachers' practices from teacher-centredness to learner-centredness, in Black schools, in order to improve the situation. So far, the attempts failed to yield the desired results. This paper reports on the findings of a study that aimed at learning from students and teachers in Black schools, as to what classroom practices lead to success in school mathematics, in their impoverished context.This revised version was published online in October 2005 with corrections to the Cover Date.  相似文献   

Revisioning professionalism from the periphery     

Jennifer Skattebol  Elizabeth Adamson  Christine Woodrow 《Early Years: An International Journal of Research and Development》2016,36(2):116-131

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.  相似文献   

Introduction to this Special Issue     

Lina?KashyapEmail author 《International journal for the advancement of counseling》2004,26(4):337-339

In 2001, for the first time in the history of the International Association for Counselling, International Conference was held in a developing Asian country–India, with the theme Families in Transition–Counselling in Transition–Meeting the Challenges Ahead. This special issue contains some of the presentations made by Indian participants during this conference which best reflect the challenges and diversities of counseling efforts with families in India. The first article was specially written for this issue in order to give an international relationship of this journal an in depth contextual understanding of Indian families in transition and the challenges they pose to the contemporary Indian counselor. Two articles are reflected to counseling families affected by socio-politial and economic changes. Five authors have written on counseling related to physical and mental disability/addiction and last two articles are reflected to authors experiences as family counselors.  相似文献   

A case of IgA multiple myeloma: Nutritional perspective in diagnostic testing     

J. I. Anetor  F I Ajose  T. S Akingbola 《Indian journal of clinical biochemistry : IJCB》2005,20(1):193-197

A 64-year-old security guard and longstanding known hypertensive presented with hypertensive heart disease (HHD), weight loss, an enlarged prostate, and a spontaneously fractured rib. Malignancy of the prostate with possible metastases to the ribs was strongly suspected. Biochemical profiling revealed a paraprotein. Other biochemical and hematological correlates that were on hand before serum protein electrophoresis were rather atypical. Paraprotein studies by immunofixation revealed IgA myelomatosis. Unlike previous reports from Caucasians there was normocalcaemia, normal protein level, microcytic hypochromia, low MCHC, cholesterol level at the lower limit of the reference range and normal urea level (in the face of markedly raised creatinine level). Nutritional modulation of the classical laboratory features of this disease may account for the fairly atypical laboratory picture. The need to appreciate the influence of nutritional status on the laboratory (especially biochemical) features of a disease and thus interpretation of diagnostic tests appears of exceptional current importance, given the widening gap in socioeconomic status and the level of poverty between the resource poor and developed countries from which the classical, clinical and laboratory features of most diseases were first described. This case report reminds of the need not only to recognize theoretically the impact of nutritional status on the laboratory characteristics of a disease but of the practical application of the nutritional perspective in the interpretation of diagnostic investigations, especially in nutritionally disadvantaged communities.  相似文献
