A长白山是一座死火山,山脚下土层厚的地方森林茂密,但是随着海拔的增加,覆盖山体的便都是黑色的火山石和白色的火山灰了。恶劣的生存环境,使高大的乔木,甚至是灌木都望而却步了。 相似文献

也许是与石头打了二十年交道的缘故,杨树锋看上去也象岩石那样质朴、沉稳,连他的工作室也是除了一堆堆的花岗石和火山石别无多物。应该说,杨树锋走过的是一条曲折而坚实的人生道路。生于西子湖畔的杨树锋,中学毕业适逢“史无前例”的十年动乱,1969年插队去了山区农村。幸运的是,他被乡亲们和组织上推荐,成了“工农兵学员”,就学于南京大学地质系。1981年,杨树锋获硕士学位,1984年成为中国首位自己培养的地学博士。1991年他又走马上任浙江大学地科系主任,兼应用地质研究所所长,他还是国家教委科技委员会和地质学教育指导委员会成员。 相似文献

This study investigates the relations between teachers’ attitudes towards persons with intellectual disability (ID), in-service training on ID, and prior contacts with persons with ID. A sample of Canadian elementary school teachers (N?=?118) completed the Attitudes Toward Intellectual Disability Questionnaire, which measures cognitive, affective and behavioural components of attitudes towards persons with ID. Correlational and multivariate regression analyses were performed. Frequent contacts with persons with ID and experience of including a child with ID increased the likelihood of reporting prior positive contacts with persons with ID. In turn, this was associated with less discomfort towards persons with ID and more willingness towards interactions. In-service training on ID was related to better knowledge of rights and capabilities of persons with ID. Experience of including a child with ID in general education classrooms increased the likelihood to report feeling competent in teaching children with ID, which predicted more willingness to include children with ID. 相似文献

This study explores the attitudes of future professionals working with students with disabilities towards four exceptionality groups: persons with deafness, with paralysis, with mental retardation (MR) and with delinquent behaviour, and specifically examines how deafness is perceived in comparison with the three other groups. Undergraduate students' (N=177) attitudes towards the four groups were tapped using a semantic differential scale referring to the cognitive, emotional and behavioural components of attitudes. Participants' degree of contact with people with disabilities was also reported. Results indicated that attitudes towards people with deafness were more positive than those towards the other three groups. Attitudes towards persons with paralysis were more positive than towards persons with MR and with delinquent behaviour, except when personality was considered. Emotional reactions and behavioural tendencies towards persons with delinquent behaviour were the most negative. Contact with people with disabilities had significant but low correlations with some aspects of the attitudes towards people with MR and paralysis. In general, the results of this study suggested that deafness was perceived as a physical disability and not as a social phenomenon. They also demonstrated that attitudes towards people with disabilities are a function of the particular disability condition and are multidimensional. 相似文献

AbstractThis study has a twofold objective: to analyse and compare the phonological processes in a sample of Spanish children with hearing loss, both with a cochlear implant and with a hearing aid, with a group with normal hearing; and to determine whether there are differences between the participants with a cochlear implant and with a hearing aid in the frequency and nature of the phonological processes. The sample is made up of 168 participants, eight with hearing loss (four with an implant and four with a hearing aid) and 160 with normal hearing. Samples of spontaneous speech were collected and transcribed using the tools from the CHILDES project. For the analysis, the phonological processes paradigm was adopted, evaluating phonological development based on normative error rates. The participants with a hearing loss show slower phonological development in terms of phonological processes, along with atypical processes. Furthermore, the participants with cochlear implants committed more phonological errors than those that wear a hearing aid. The implications of the results are discussed, and it is recommended that auditory stimulation should be done early in children with hearing loss regardless of their technical aid. 相似文献
