试论老子以天子-平民为核心的“点-面”政治思想     

戚震南  李树森 《山西大学师范学院学报》2006,5(1):10-12

老子的政治思想有其自身的整体性。很少有人将他的政治思想进行系统研究，从而造成了对他政治思想的不少误解。老子的政治思想是以天子-平民的“点-面”结构为核心的政治体系。“小国寡民”是当时的社会历史条件下的政治设计，实际上是要建立一种“大社会，小政府”的国民自治体系。通过对此政治体系结构的阐述，对其运行机制及其对中国古代政治发展的一系列影响的分析，可以在新的视角下对老子的政治思想做到尽量正确而全面的评价。  相似文献   

Psychosocial correlates of child abuse potential in multiply disadvantaged adolescent mothers     

Budd KS  Heilman NE  Kane D 《Child abuse & neglect》2000,24(5):611-625

OBJECTIVE: This study had two aims: First to examine psychosocial correlates of child maltreatment risk, and second to assess the validity of the CAP Inventory (Milner, 1986) with multiply disadvantaged teenage mothers. METHOD: Participants were 75 adolescent mothers who were wards of the Illinois child protection system. Mothers (aged 14-18) and infants participated in home-based psychosocial assessment of personal and parenting functioning. Group comparisons examined differences for mothers with elevated versus normal versus invalid CAP scores due to faking good. RESULTS: Findings indicated that abuse risk groups differed on emotional distress, social support satisfaction, reading achievement, and years of education, but not on parenting beliefs or quality of child stimulation. Differences favored the normal over the elevated risk group in all significant comparisons, whereas mothers with elevated faking good differed from normals only in lower reading achievement. Multiple regression analysis highlighted emotional distress, support dissatisfaction, and low achievement as significant predictors of greater abuse risk. CONCLUSIONS: Despite sharing multiple disadvantages, adolescent wards are a heterogeneous group who show different levels of psychosocial functioning corresponding to levels of child maltreatment risk. The findings provide support for the concurrent validity and clinical applicability of the CAP Inventory with disadvantaged teenage mothers.  相似文献   

Instructing adolescents with learning disabilities: converting a meta-analysis to practice     

Swanson HL  Deshler D 《Journal of learning disabilities》2003,36(2):124-35; discussion 149-50

A previous meta-analysis indicated that eight instructional factors--Questioning, Sequencing and Segmentation, Skill Modeling, Organization and Explicit Practice, Small-Group Setting, Indirect Teacher Activities (e.g., homework), Technology, and Scaffolding-captured the majority of successful intervention programs for adolescents with learning disabilities (LD). Most important was the Organization/Explicit factor, which contributed significant variance (16%) to effect size. This factor included two important instructional components: advance organization and explicit practice. In this article, we convert these findings into practical guidelines to direct instructional practice.  相似文献
