The authors evaluate and advocate the need for comprehensive sexuality education that meets the unique needs of youth who are deaf or hard of hearing, while calling for the expansion of teacher preparation in this critical area. Effective comprehensive sexuality education is designed to prepare young people to become more comfortable with, and informed about, their sexuality. Teachers and parents are key adults in this process. However, the responsibility for preparing teachers to handle sexuality education lies with both the postsecondary teacher preparation program and the administrative team at the individual school; their willingness to provide comprehensive training, current resources, and continued support are crucial to the success of any comprehensive sexuality program. In the individual school, effective guidance of youth who are deaf or hard of hearing in making appropriate decisions about their sexuality is built upon a team that includes not only school staff, but also parents and deaf adults in the community.  相似文献

Existing applications of event history modeling in attrition research typically focused on the first departure. This study extends the scope of existing applications by dividing each student’s enrollment history into periods of enrollment and non-enrollment (spells). The findings indicate that departure is strongly associated with poor college grade performance and part-time enrollment. Students receiving financial aid are more likely to persist. The probability of return is higher for students whose parents attended college, those with higher SAT scores and coming from nearby areas. The duration of previous spells has a positive impact on the probability of return and a negative impact on the probability of departure.  相似文献

"The aim of this paper is to examine Sudan's development conditions, using its national censuses as indicators of the status of the country, with special reference to the 1983 census, the last census in Sudan." The importance of taking migration into account when examining the prospects for development is stressed. The author also describes available demographic data sources for the Sudan, including the censuses of 1955-1956 and 1973. Sections are included on population size and growth, sex and age distribution, spatial distribution, population density, mortality, migration, illiteracy, and the labor force.  相似文献

Nine years after child sexual abuse   总被引:7,自引:0,他引:7  
OBJECTIVE: During 1988-1990, 103 children presented to Child Protection Units (CPU) at two children's hospitals in Sydney, Australia. Nine years later, the psychological adjustment of these young people (mean age=19.1 years, SD=3.4 years; range=14-25 years) was compared with that of non-abused young people of similar age and gender to assess group differences and examine potential risk factors. METHOD: At intake, data on the nature of the index sexual abuse, demographics and the family environment were collected by clinicians. A comparison group, of similar age and gender, was selected from schools in the catchment area of the CPUs. Six years after presentation for the abuse, records of the statutory child protection authority were checked to determine any further notifications for abuse and/or neglect. Nine years after intake, 49 of the abused young people and 68 of the non-abused young people and/or their parents were interviewed and assessed. RESULTS: The sexually abused young people performed more poorly than non-abused young people on psychometric tests of depression (p=.001), self-esteem (p<.001), anxiety (p<.001), behavior (Child Behavior Checklist: p=.01; Youth Self Report: p=.01; Young Adult Self Report: p<.001), and despair (p=.001). They were also more likely to have a history of bingeing (p=.002), self-inducing vomiting (p=.02), smoking cigarettes (p=.01), and using amphetamines (p=.002), ecstasy (p=.002) and cocaine (p=.004). Potential risk factors were in two groups, family and child. Family factors: family functioning, parental drug/alcohol problems, mother's sexual abuse history, mother's depression and socio-economic status. Child factors: despair and hopefulness, number of negative life events, ratings of their father's care, previous notifications for child sexual abuse and placements in out-of-home care by the statutory child protection authority. In the presence of other risk factors, child sexual abuse was a significant predictor of self-esteem, behavior and bingeing. CONCLUSIONS: Rather than focusing only on the individual's child sexual abuse, treatment may also need to address the family's functioning and the individual's feelings of despair.  相似文献
