Financial Issues Associated with Having a Child with Autism 总被引:2,自引:2,他引:0
Data from the Family Experiences with Autism Survey are used to identify factors associated with financial problems in families
that have a child with autism. Likelihood of financial problems was positively associated with use of medical interventions,
having unreimbursed medical or therapy expenses, and having relatively lower income. Use of speech and language therapy was
negatively associated with likelihood of financial problems. Many survey respondents forfeited future financial security and
even experienced bankruptcy to provide needed therapy for a child with autism. Specific ways that financial advisors can help
families that have a child with autism are outlined.

While the relationships between health insurance and the labor supply of women have been explored in the literature, little
is known about the effects of offering public health insurance on the labor supply decisions of married women. This paper
examines how the enactment of the State Children’s Health Insurance Program (SCHIP) affected the labor supply decisions of
married women. Our empirical analysis showed that certain groups of married women reduced their number of hours worked upon
SCHIP implementation. The results imply it is possible that some wives decreased their labor supply in order to make their
children eligible for public health insurance.

Although it would be safe to say that Lesbian Studies has never seriously been placed on the Japanese academic agenda, women-loving-women in Japan continue to individually and collectively desist from and resist heteronormative gender discourses. This paper first gives a brief overview of 'rezubian' communities since the 1970s and then outlines the Basic Law for a Gender Equal Society and the Law Concerning Special Rules Regarding Sex Status of a Person with Gender Identity Disorder; two recent laws that demonstrate contemporary regulatory gender discourses. In closing, I stress that the paradox of contemporary Japanese 'lesbian studies,' being almost nonexistent in the academe and continuously in development in the community, is clear only if we look at academic discourses alongside writings in both commercial and community publications. 相似文献

A product has been formally denned as being subject to sudden obsolescence if its lifetime is negative exponentially distributed. Using an approximate model, Masters suggested that the traditional method of incorporating obsolescence cost as a component of inventory holding costs in the economic order quantity (EOQ) model was appropriate-for products subject to sudden obsolescence, provided that the obsolescence cost component was computed properly. Unfortunately, current practice of the EOQ model seriously underestimates the costs of sudden obsolescence. An exact model demonstrating that Masters' model also underestimated true lifetime costs and overestimated the optimal order quantity has been presented. Neither of these models addressed quantity discounts. Furthermore, with their cost-minimization focus, these models fail to identify situations when minimized costs exceed expected revenues. We extend Joglekar and Lee's model to focus on maximizing profits, rather than minimizing costs. This model answers such questions as whether to stock the product at all, whether to accept a quantity discount offer, and what order quantity to use. Numerical examples and sensitivity analyses suggest that Masters' model provides a significant improvement over the traditional model in moving toward true optimality. However, they also illustrate situations where both the traditional and the Masters' model accept a quantity discount that deserves to be rejected and stock a product that should not be stocked. In such situations, it seems important that a retailer uses the profit-maximization model presented here. 相似文献

This study examined the prevalence of workplace flexibility and the mechanisms that allow workplace flexibility to influence turnover intentions through work–family and family–work conflicts and job satisfaction among low‐wage workers in South Korea. Participants included 250 low‐wage workers whose monthly salary was less than 2 million Korean won (approx. $1,900). The study results indicate that low‐wage workers have limited access to workplace flexibility and that workplace flexibility plays a significant protective role in reducing their turnover intention, indirectly by decreasing work–family conflicts and enhancing job satisfaction. This article also discusses the implications of these findings for labor policy and social work practice. 相似文献

South Korea has been experiencing rapid population aging. In an aging society, the need for healthy lives is greater. Two of the fundamental factors to enable independent and active life for the elderly are mobility and social participation. The purpose of this study was to examine the relationship between older adults’ mobility, social participation, and quality of life in South Korea. We used data from the 2017 National Survey of Older Koreans conducted by the Ministry of Health and Welfare and the Korea Institute for Health and Social Affairs and applied hierarchical regression. The major finding was that older adults’ mobility had a positive impact on their life satisfaction. After controlling for older adults’ mobility, social participation was positively associated with life satisfaction regardless of the place of residence. The findings of this study not only make a valuable contribution to further research on mobility and social participation but also provide new insight into improving older adults’ quality of life. 相似文献

The present research examined how school contexts shape the extent to which beliefs about the potential for change (implicit theories) interact with social adversity to predict depressive symptoms. A preregistered multilevel regression analysis using data from 6,237 ninth‐grade adolescents in 25 U.S. high schools showed a three‐way interaction: Implicit theories moderated the associations between victimization and depressive symptoms only in schools with high levels of school‐level victimization, but not in schools with low victimization levels. In high‐victimization schools, adolescents who believed that people cannot change (an entity theory of personality) were more depressed when they were victimized more frequently. Thus, the mental health correlates of adolescents’ implicit theories depend on both personal experiences and the norms in the context. 相似文献

Technology is pervasive in homes of families with young children, despite evidence for negative associations between infant exposure to screen‐based media and cognitive development that has led the American Academy of Pediatrics (AAP) to discourage parents from exposing children under the age of 18 months to any kind of screen time (AAP, 2016). Here, we apply a propensity score matching approach to estimate relations between electronic screen‐based media use in infancy and executive function in early toddlerhood. In an international sample of 416 firstborn infants, parental report of regular exposure to screen‐based media at 4 months predicted poorer performance on a test of inhibition at 14 months, but was unrelated to either cognitive flexibility or working memory at 14 months. Results of this study are therefore consistent with the view that early exposure to screen‐based media adversely affects the development of executive function. 相似文献
