This study assessed the feasibility of doing hearing screening in Migrant, American Indian and Early Head Start programs using otoacoustic emissions (OAE) technology. Staff members were trained to screen 0–3-year-old children for hearing loss using hand-held OAE equipment and a multi-step screening and referral protocol. Of the 3486 children screened as a part of the study, 77% passed an OAE screening at the first step, 18% more passed an OAE screening at the second step, and 5% were ultimately referred for medical or audiological follow-up. Eighty children were identified as having a hearing loss or disorder of the outer, middle or inner ear requiring treatment. Of these 80, six had permanent bilateral or unilateral hearing loss. Although the protocol suggested that the multi-step screening procedure should be completed within a 4-week time period or less, analysis of the data showed that for children requiring more than an initial OAE screening, the length of time over which the screening was completed ranged from 7 to 12 weeks. The median time required to complete a single OAE screening session was 4 minutes per child. The results demonstrate that OAE screening of young children using this protocol is practical and effective. The implications for conducting periodic hearing screening throughout early childhood are discussed.  相似文献

In New South Wales, Australia, the Department of Youth and Community Services is empowered by statute to deal with cases of child abuse and neglect. Its child protection services include the Montrose Child Life Protection Unit which is designed to support and complement the work of both the Intake Service, Field Service and most importantly the work of child protective facilities in the community. The service has intake crisis counselling and call out resources; maintains a central register; provides a facility for crisis residential care for children and families, diagnostic assessment, and a day programme. The emphasis in service delivery in New South Wales in the area of child protection is on multidisciplinary intervention. The Department of Youth and Community Services is involved in promoting interagency cooperation and co-ordination. Over and above a philosophy that underlies service delivery is the Montrose Unit's involvement in sensitising the community to the difficult and often demanding role of parenting. Montrose represents an attempt to create an environment where parenting myths can be examined from a reality base and strategies implemented for reeducation.  相似文献

According to Healthy People (2011), in order to understand the health concerns of the Lesbian, Gay, Bisexual, and Transgender (LGBT), the oppression and discrimination that they have faced must be scrutinized. Among the many issues they face, their estrangement experiences are one of the most understudied. However, little is known about how it is experienced by the gay elderly population, hence, this investigation. This grounded theory purports to describe the process by which estrangement is experienced among the Filipino gay older adults. Strauss and Corbin’s Grounded Theory (1990) design was utilized. A total of 10 gay older persons were purposively chosen to participate in semi-structured interviews. Field texts were subjected to thematic analysis involving open, axial, and selective coding. The study generated The Sailing Model of Estrangement. Remarkably, three phases relative to estrangement emerged, namely: sequestering, striving, and surviving. Primarily, the sequestering phase involves the gay persons’ need to express self, search for acceptance, and its subsequent reactions. The striving phase typifies the struggle in dealing with estrangement leading to either feelings of depression, remorse and shame or positivity, hopefulness, and motivation. Finally, in the surviving phase, gay persons may either feel contented and fulfilled or sad, lonely, and remorseful as they acquiesce aging with estrangement. Findings of the study offer an understanding of how Filipino gay older adults employ coping strategies in response to estrangement.  相似文献

The thesis of this paper is that to be gifted means being able to go through the developmental curve from novice to expert more rapidly. Central in growing expertise are the building up of pattern recognition capabilities, schema formation, proceduralization of the knowledge base, and the development of a multistrategy control structure. However gifted the person, in most domains this development takes thousands of hours of hard work. For this reason the contribution to success of sheer intellectual ability is hypothesized to be overshadowed by the personal and situational characteristics that have been found to differentiate between actually (not potentially) creative and less creative persons, e.g., an early, passionate, personal interest in a domain.  相似文献

In this study, the reading comprehension of deaf children and adolescents in the Netherlands is examined along with their word identification. The reading comprehension of 464 deaf students and the word identification of 504 deaf students between 6 and 20 years of age was examined. The results show the reading comprehension scores of deaf children to be far below the scores of hearing children. On average, the deaf subjects scored at a level equivalent to a hearing child in the first grade. The word identification scores of the deaf children, however, were almost equivalent to the scores of hearing children. Although reading comprehension and word identification appear to be related, this relation does not completely explain the comprehension difficulties encountered by deaf children. Additional factors are required to explain deaf children’s difficulties with reading comprehension.  相似文献

The Netherlands form a consensus democracy. In such a society the legitimacy of decisions is of great concern to all. An elaborate system of checks and balances tends to exist and the pressure to join an emerging consensus at meetings is both subtle and tremendously powerful. In the Dutch system of higher education and research the manifestations of the consensus ideal are numerous. This paper highlights them where appropriate. It reviews the Dutch research effort in an international perspective and concludes that R&D expenditure in the Netherlands, measured as a proportion of GDP, is declining. Fairly radical changes in science policy orientation since the 1960s are reviewed and the current frameworks for policy formulation, academic foresight and the organisation of support are sketched. After discussing NWO's different funding instruments, the practices of picking the winners are described in some detail. Three different peer review models are then discussed with special attention to their strengths and weaknesses. The paper's final section is focussed on the evaluation practices in force.  相似文献

The Bologna Process of higher education reform has led to a vast array of different programs of study in German teacher training. In this article, we firstly analyze the implementation of Bachelor programs in teacher training, comparing profession-oriented programs (i.e. those aiming to train students for the teaching profession from the beginning of studies) to polyvalent programs (i.e. those aiming at broad qualifications and including a late decision to become a teacher). Secondly, we investigate whether students enrolled in these study programs differ systematically in their subjective certainty about their career choice. To answer these questions, we analyze portfolios of documents related to teacher training programs from nine German universities that prepare students for teaching in the academic track. Additionally, we analyze data from N?=?2585 Bachelor and N?=?928 Master degree students. We found that most programs, even when they espouse polyvalence, require an early decision to become a teacher. Moreover, our data confirm findings from earlier studies indicating that student teachers are highly certain about their career choice from the very beginning, with students in polyvalent programs being slightly less certain than those in profession-oriented programs (d?=?0.32).  相似文献
