Abstract

Parents of children with autism experience elevated stress that may be influenced by specific characteristics of the child and parent, including cultural norms and beliefs about parenting. However, there is little research on families of children with autism from cultural perspectives. The purpose of this integrative review is to identify factors influencing parenting stress in mothers of children with autism in Japan. A final sample of 15 primary research articles (2000–2015) on parenting stress in mothers of Japanese children with autism was selected using several databases. The findings suggested that these mothers experience much greater parenting stress than mothers of typically developing children and children with other disabilities. Japanese mothers also demonstrate stress related to attachment difficulties, low parenting efficacy and lack of support, reflecting Japanese parenting styles and gender ideology. Parent-directed and culturally calibrated interventions are needed to support parents of children with autism, especially cultural minority parents.  相似文献

中国种子植物特有属的数量分析   总被引:3,自引:0,他引:3  
Chinese flora with many endemic elements is highly important in the world’s flora. According to recent statistics there are about 196 genera of spermatophytes, be- ing 6.5% of total Chinese genera.  These endemic genera comprising 377 species belong to 68 families, among which the Gesneriaceae (28 genera), Umbelliferae (13), Compo- sitae (13), Orchidaceae (12) and Labiatae (10) are predominant.  The tropical type containing 24 families and 80 genera is dominant. After it follows the temperate type with 23 families and 50 genera.  There are also 4 families endemic to China, i.e. Gin- kgoaceae, Bretschneideraceae, Eucommiaceae and Davidiaceae.  It shows that genera endemic to China are obviously related to the tropical and temperate flora in essence.      The endemic monotypic genera (139) and endemic obligotypic genera (48) combin- ed make up more than 95% of the total number of genera endemic to China.  Phylo- genetically more than half of them are ancient or primitive.  The life forms of all ende- mic genera are also diverse.  Herbs, especially perennial herbs, prevail with the propor- tion of about 62%, and trees and shrubs are the next, with 33%, and the rest are lianas.       Based upon the calculated number of genera endemic to China in each province and the similarity coefficents between any two provinces, some conclusions may be drawn as follows:       Yunnan and Sichuan Provinces combined are the distribution centre of genera en- demic to China and may be their original or  differentiation area,  because  numerous endemic genera, including various groups, exist in these two provinces.  The second is Guizhou where there are 62 endemic genera.  Others form a declining order, south China, central China and east China. But towards the north China endemic genera de- crease gradually, and the Qinling Range is an important distributional limit.       The largest simitarity coefficient, over 50%, appears between Shaanxi and Gansu probably because of the Qinling Range linking these two provinces.  But between any other two provinces it is less than 30% and it is generaly larger between two south pro- vinces than between two north provinces.       These characteristics mentioned above are correlated with topography and climate, and they may be resulted from the diversification in geography and climatic influence for a long time.  相似文献
