INTRODUCTION Human limbs are complex, delicate systems.Their reconstruction, both for appearance and forfunction compensations, proves to be complicatedprojects. With the development of science and tech-nology, both researchers and disabilities hope to haveartificial limb much more perky, comfortable, dex-terous and effective. Although thousands of pros-thetic limbs are commercially available worldwide,most of them, from mechanical styles to electricstyles, from motion controlled t…  相似文献

Self-assessments and other perceptions of successful adults who are deaf: an initial investigation     

Luckner JL  Stewart J 《American annals of the deaf》2003,148(3):243-250

More often than not, deafness is portrayed, not only in the literature in education and rehabilitation but in society in general, in a pathological way that focuses on deficiency, dysfunction, and deviance. Consequently, there has been a paucity of research on successful individuals who are deaf. The purpose of the present study was to help counter this tendency by gathering information from successful deaf adults. Fourteen deaf adults, who were nominated by their peers as being successful, participated in videotaped interviews. The interviews were transcribed, coded, and clustered according to common themes. Participants reflected on their success and made recommendations for children and youth who are deaf, parents, teachers, and employers. A summary of the results, limitations of the study, and recommendations for practice are provided.  相似文献

Inter-Parietal White Matter Development Predicts Numerical Performance in Young Children     

Cantlon JF  Davis SW  Libertus ME  Kahane J  Brannon EM  Pelphrey KA 《Learning and individual differences》2011,21(6):672-680

In an effort to understand the role of interhemispheric transfer in numerical development, we investigated the relationship between children's developing knowledge of numbers and the integrity of their white matter connections between the cerebral hemispheres (the corpus callosum). We used diffusion tensor imaging (DTI) tractography analyses to test the link between the development of the corpus callosum and performance on symbolic and non-symbolic numerical judgment tasks. We were especially interested in the interhemispheric connections of parietal cortex in 6-year-old children, because regions of parietal cortex have been implicated in the development of numerical skills by several prior studies. Our results revealed significant structural differences between children and adults in the fibers of the corpus callosum connecting the left and right parietal lobes. Importantly, these structural differences were predictive of individual differences among children in performance on numerical judgment tasks: children with poor numerical performance relative to their peers exhibited reduced white matter coherence in the fibers passing through the isthmus of the corpus callosum, which connects the parietal hemispheres.  相似文献   

Relations of Children's Effortful Control and Teacher-Child Relationship Quality to School Attitudes in a Low-Income Sample     

Silva KM  Spinrad TL  Eisenberg N  Sulik MJ  Valiente C  Huerta S  Edwards A  Eggum ND  Kupfer AS  Lonigan CJ  Phillips BM  Wilson SB  Clancy-Menchetti J  Landry SH  Swank PR  Assel MA  Taylor HB;School Readiness Consortium 《Early education and development》2011,22(3):434-460

RESEARCH FINDINGS: The purpose of this study was to examine the relations of children's effortful control and quality of relationships with teachers to school attitudes longitudinally in an ethnically diverse and economically disadvantaged sample. Data were collected as part of a larger intervention project during mid-fall, winter, and late spring (ns = 823, 722, and 758, respectively) for 2 cohorts of 3- to 5-year-olds (collected during 2 different school years). Children's effortful control was assessed in the fall with parents' and teachers' reports and 2 behavioral measures. Teacher-child relationship quality was assessed mid-year with teachers' reports of closeness and conflict. Attitudes toward school were assessed in late spring using teachers' and students' reports of school avoidance and liking. Effortful control, in general, was positively correlated with teacher-child closeness and school liking and negatively correlated with conflict and school avoidance. Using structural equation modeling and controlling for sex and ethnicity, we found that effortful control was positively related to teacher-child relationship quality, which in turn was positively related to school attitudes. Furthermore, the relation of effortful control to school attitudes was mediated by teacher-child relationship quality. PRACTICE OR POLICY: Results provide evidence for the importance of relational processes that take place within the classroom context and have implications for teachers and clinicians working to increase school success in ethnic minority and low-income children.  相似文献   

Dayton William Dix's Birth Story     

Hirschenfang J 《The Journal of perinatal education》2011,20(2):70-75

In this birth story, a young mother relates her experience of moving beyond fear of labor and birth and developing confidence in her ability to give birth without an epidural. Knowledge and support, including the support of a doula, during the last months of pregnancy helped this mother change her plans for the labor and birth. This story highlights the importance of continuous emotional and physical support and how knowledge and confidence set the stage for a satisfying, safe, and healthy birth.  相似文献   

Effect of postsecondary education on the economic status of persons who are deaf or hard of hearing     

Schley S  Walter GG  Weathers RR  Hemmeter J  Hennessey JC  Burkhauser RV 《Journal of deaf studies and deaf education》2011,16(4):524-536

This article examines the effect that postsecondary education has on earnings and the duration of time spent in the Social Security disability programs for young persons who are deaf or hard of hearing. Our hypothesis is that investments in postsecondary training increase the likelihood of employment for persons who are deaf or hard of hearing and thus reduce dependency on disability-related income support programs. A longitudinal data set based upon records from the National Technical Institute for the Deaf and Social Security administrative records is used for this analysis. We find that those who graduate, even those who graduate with vocational degrees, experience significant earnings benefits and reductions in the duration of time spent on federal disability programs when compared with those who do not graduate with a degree. This finding suggests that reductions in the duration of time spent on Social Security programs are not limited to those with the highest level of scholastic aptitude and that investments in post-secondary education can benefit a broad group of deaf and hard-of-hearing persons. In addition, the data show that individuals who attend college, but withdraw before graduation, fair no better economically than individuals who never attended college.  相似文献   

Prenatal parenthood     

J O'Leary  J Warland  L Parker 《The Journal of perinatal education》2011,20(4):218-220

In this article, we discuss the intuitive knowledge mothers have of their unborn baby. We propose a shift in focus from caregivers' merely providing information to first listening to pregnant mothers as they share their intuitive knowledge of their baby. This approach enables mothers and fathers or partners to know they are already parents to their unborn baby and empowers them to get in touch with their baby's presence and who he or she is during pregnancy. This intuitive knowledge may be a protective behavior that will enable mothers to keep babies safe during pregnancy.  相似文献
