The article describes the technology transfer concerns reported by a small sample (N=14) of recent college graduates with disabilities. In structured, in-depth interviews, researchers asked respondents to reflect on the extent to which they had utilized technology resources during their college years in preparation for the world of work. Results suggest that colleges and universities need to play a more active role in introducing students with disabilities to both generalized and assistive technology services.  相似文献

A study of 240 YMCA organizations revealed that regardless of organization size, those organizations that used a formal approach to strategic planning had higher levels of financial and social performance than those with less formal processes. The better performers also assigned the responsibility for planning to a strategic planning subcommittee of the board rather than to the board's executive committee or to an outside consultant.  相似文献

Self-rated health as a predictor of mortality has been studied primarily in large, representative populations, with relatively little progress toward understanding the information processing that individuals use to arrive at these ratings. With subsamples of National Health and Nutrition Examination Survey (NHANES) Epidemiologic Follow-up Study (NHEFS) data for respondents with circulatory system disease (N = 3,709) and respondents with no diagnosable disorders (N = 1,127) at baseline, we test the idea that individuals with experience of chronic disease of the circulatory system will have more predictive self-ratings of health than healthy individuals. Poor or fair self-rated health increased the adjusted hazard of all-cause mortality for respondents with circulatory system disease, but not for respondents who were healthy. Additional analyses confirm that poor or fair self-rated health is particularly predictive for respondents with self-reported history of circulatory system diagnoses and perception of symptoms, but not for respondents without symptoms or diagnoses prior to the NHANES physical exam.  相似文献

Underemployment of people with visual impairments is an important problem in the world of work. Barriers to successful employment include the lack of informed decision making concerning AT as a workplace accommodation. Choosing effective Assistive Technology (AT) as an accommodation solution is imperative to successful employment of individuals with vision impairments. While not all jobs require AT as a part of an accommodation, when AT is needed, an informed choice is the best approach. This article describes the five step process for selecting appropriate AT for individuals with vision impairments in workplace accommodations developed by the Job Accommodation Network (JAN). Cases from the JAN database that involve people with vision impairments were examined. Resources to enable readers to further evaluate and implement effective AT solutions are provided.  相似文献

Where strength training has been used in conjunction with functional-task training in older people, not only have there been improvements in leg strength but also improved function has been measured (e.g., Skelton & McLaughlin, 1996). Many studies use participants from care homes rather than community dwellers. We investigated changes in leg power, balance, and functional mobility in community-dwelling sedentary men and women over 70 years of age (n = 6 for training group [TR]; n = 10 for control group [CN]). Progressive training took place over 24 weeks using seated and nonseated exercise. For TR, leg power increased 40%, from 108 +/- 40 to 141 +/- 53 W (p < .01); dynamic balance increased 48%, from 22.3 +/- 7.9 to 33.1 +/- 6.1 cm (p < .01; functional reach); and functional mobility increased 12%, from 7.46 +/- 1.32 to 6.54 +/- 1.41 s (p < .05; timed walk). CN showed no significant change. In conclusion, a community-based exercise program led to large improvements in leg-extensor power, dynamic balance, and functional mobility.  相似文献

Adolescence is the segment of the life course when gender differences in mental health emerge and gender becomes a more salient factor shaping orientations toward oneself and views of one's place in the social world. This study uses mixture modeling, to identify trajectories of masculinity and femininity between ages 12 and 25, and OLS regression, to examine the effects of those trajectories on mental health in young adulthood (measured as depressive symptoms and alcohol problems at age 25). Four waves of prospective data from the Rutgers Health and Human Development Project are used; respondents (n = 447) are age 12 at Wave 1 (1979-81), 15 at Wave 2 (1982-84), 18 at Wave 3 (1985-87), and 25 at Wave 4 (1992-94). Results indicate that having relatively high and increasing levels of masculinity over adolescence decreases depressive symptoms in early adulthood for both males and females. Reflecting the privileging of males over females, the findings suggest that masculinity, but not femininity, is a central axis on which advantages and disadvantages across some dimensions of mental health accumulate over adolescence.  相似文献

1. Surgically or chemically induced premature menopause is a life transition characterized by a situational crisis superimposed on a developmental crisis. 2. After surgically or chemically induced premature menopause, women's self-concept shifts and evolves through an interactive or relational process. 3. Nurses can use crisis management to increase women's understanding of the physiological and psychological dimensions of premature menopause, facilitate their links with community support systems, and strengthen their existing social networks. 4. Effective crisis intervention approaches include structuring, verbalizing, clarifying, normalizing, and supporting.  相似文献

The present study examined the impact of domestic violence on maternal and infant health by assessing maternal health during pregnancy and infant health at two months postpartum. Two hundred and two women (68 battered and 134 non-battered) were recruited from the community and completed both pregnancy and 2-month postpartum interviews. Results revealed that domestic violence during pregnancy was associated with numerous health problems for mothers and infants including more health problems during pregnancy, more likelihood of premature labor, later entrance into prenatal care, lower infant birth weight, greater utilization of health care resources, and more prenatal substance use. After income was controlled, the relationship between violence and timing of prenatal care and infant birth weight became nonsignificant. Maternal social support was found to protect against the effects of violence for several health outcomes. The current findings suggest the need for domestic violence screening during pregnancy, as well as clinical interventions for battered, pregnant women in order to prevent serious physical and emotional problems for both mothers and their infants.  相似文献
