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

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

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

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

Drawing upon a post-structural ethnography of boys’ constructions of gendered and sexual identities in one South African high school, this paper empirically seeks to theorise how 20 Grade 8 boys, identified as The Jokers, The Achievers, The Outcasts and The Average Ou's, simultaneously seek out spaces in male peer culture to cultivate, police and challenge hegemonic notions of masculinity. The paper illustrates the construction and positioning of masculinities across spaces of conflict, more particularly, the personal and social resources reproduced by boys in the pursuit of ‘desirable’ masculinities across experiences of interpersonal conflict, punishment, friendship and play. Given the nature of these identity struggles in school boy peer culture, this paper highlights the need for fostering and maintaining peer conversational spaces where boys and girls are challenged to actively deconstruct prevailing gendered identities and work towards more expansive definitions of self. 相似文献
