The present study examined how vulnerability and protective factors at the individual level (child’s disabilities; patterns of attachment), and at the family level (fathers’/mothers’ affect), help explain differences in socioemotional and behavioural adjustment among children aged 8–12 years with comorbid learning disability (LD) and attention deficit hyperactivity disorder (ADHD) or with typical development. Participants were 118 father–mother–child triads: 59 couples and children with comorbid LD/ADHD and 59 couples with typically developing children. Preliminary analyses indicated significant group differences on all children’s measures and on fathers’ and mothers’ affect measures. As hypothesised, findings showed the contribution of parents’ positive and negative affect to children’s adjustment, with differences for fathers’ versus mothers’ affect. Discussion focuses on understanding the unique value of fathers’ and mothers’ affect on children’s well‐adjusted functioning. 相似文献

Introduction Our most developed and established system of communication is, of course, language. But what we mean by language is a widely recognized problem and the term 'language' has been applied figuratively to all forms of human behaviour. What is clear is that what- ever language may be, it is communicative, and it is not the only system of communication, nor is it the on- ly instrument of human communication, just the most subtle and powerful. Since the last half century, the notion of '… 相似文献

The purpose of this chapter is to offer reflections on integration research. A plea is made for a more precise and careful use of the concept “integration” and, above all, a more careful and critical interpretation of results from studies and experiences of so-called integration endeavors. Some serious misunderstandings that result from an incorrect or imprecise use of integration are pointed out. Critical distinctions between integration and inclusion are made. Results from a longitudinal study in Sweden are summarized. 相似文献

Research Findings: This study examined the heterogeneity in Spanish-speaking children's (N = 117; M age = 53 months; SD = 5 months; 57% boys) vocabulary and letter-word skills in English and Spanish after one year of preschool and the extent to which early self-regulation abilities (i.e., executive function and effortful control) were associated with that variability. Data were gathered via teacher and parent surveys and standardized assessments. Three distinct profiles of Spanish-speaking preschoolers were identified using cluster analysis. One group exhibited high levels of Spanish and English vocabulary and letter-word skills (a.k.a. high-balanced bilinguals). The other two groups exhibited predominantly Spanish or English vocabulary and letter-word skills (a.k.a. Spanish- or English-dominant). Multinomial logistic regression analyses (controlling for children's nonverbal cognitive ability) revealed that effortful control skills enhanced children's probability of being classified as high-balanced bilinguals versus Spanish-dominant; however, this was evident only for the children whose parents reported speaking exclusively Spanish at home. Executive function abilities appeared to be unrelated to preschoolers' bilingual classification, and thus their English vocabulary and letter-word skills. Practice or Policy: The findings have implications for early education programs working to increase the school readiness of Spanish-speaking children by highlighting the key role that effortful control may play in supporting their learning of English skills, particularly for those whose parents speak exclusively Spanish at home. 相似文献

This study examined the role of family-related (mother’s education, depressive symptoms and child’s gender) and kindergarten-related (teacher’s experience, teaching practices and class size) factors in mothers’ and teachers’ mutual trust in Estonia and Finland. Six hundred eighteen (206 Estonian and 412 Finnish) mothers of kindergarten children and their teachers (26 Estonian, 49 Finnish) were participated in the study. Both mothers and teachers filled in the questionnaire on trust; teachers’ teaching practices were observed with early childhood classroom observation measure. The results of multilevel modelling showed that mothers in both countries trusted more in teachers who used child-centred rather than teacher-directed practices. Teachers indicated higher trust in highly educated mothers and mothers of girls. Estonian teachers with longer work experience trusted more in mothers than less experienced teachers, and Finnish teachers trusted less in mothers reporting more depressive symptoms. The results emphasise the importance of both family-related and kindergarten-related factors in the enhancement of mutual trust. 相似文献

The purposeof the teaching and the learning of English is to develop communicative competence. Pragmatics is one of the most essential parts of the communicative competence .It concerns the appropriate use of language. This paper aims to show the significant role of pragmatics in the teaching and learning of English and further explores the importance of cultivating students' awareness to improve their pragmatic ability and communicative competence. 相似文献

The completion of the human genome project was accompanied by quite remarkable claims about the benefits for health that would follow this out-standing scientific endeavour.In this short article,I shall try to put some of these claims into perspective.Currently,the poorer countries of the world are still suffering from the effects of malnutrition,ineffective healthcare systems,and the scourges of tuberculosis,malaria,and HIV/AIDS.The richer countries are attempting to deal with the costs of… 相似文献

Type Ⅰ,Ⅲ and Ⅴ collagens were extracted from bovine dermis and cornea by using pepsin treatment in acetic acid solution,followed by salt precipitation and dialysis,to purify and isolate each type of collagens.The preparation process was analyzed by using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE).A reducing agent,2-mercaptoethanol,was used to remove disulfide bonds and analyze the structure of the bonds involved between α chains in some types of collagens.The use of delayed reducing methods resulted in the difference between α1(Ⅲ) and α1(Ⅰ) chains in a mixture containing type Ⅰ and Ⅲ collagens.The structure of disulfide bonds among α chains exists potentially in type Ⅴ collagen prepared from the pepsin-treatment extraction at 4℃,which differs from type Ⅲ collagen in relation to the locations of disulfide bonds.Compared with pepsin-treated collagen at 4℃,the relative molecular weights of α1(Ⅴ) and α2(Ⅴ) chains treated at room temperature decrease by 4.6% and 6.0%,respectively.It is concluded that type Ⅰ,Ⅲ and Ⅴ collagens can be prepared from bovine dermis and cornea by the use of pepsin treatment,salt precipitation and dialysis.The interchain disulfide bonds lie potentially near the edges of termini of type Ⅴ collagen molecules in extracellular matrix,and a small number of interchain crosslinks exist in type Ⅴ collagen. 相似文献
