An assumption of multivariate normality for a decision model is validated in this paper. Measurements for the independent variables of a bond rating model were taken from a sample of municipal bonds. Three methods for examining both univariate and multivariate normality (including normal probability plots) are described and applied to the bond data. The results imply, after applying normalizing transformations to four of the variables, that the data reasonably approximate multivariate normality, thereby validating a distributional requirement of the discriminant-analysis-based decision model. The methods described in the paper may also be used by others interested in examining multivariate normality assumptions of decision models. 相似文献

The aim of this study was to explore the lived experiences of grandparents raising their grandchildren with foetal alcohol spectrum disorder (FASD). Specifically, we sought to identify how caregivers make meaning of their experience, what challenges are faced by grandparents while raising a second generation and what positive experiences are encountered. Ten grandparents raising a child with FASD in Ontario, Canada, participated in semi-structured interviews. Interpretative phenomenological analysis was used to analyse the interviews to determine reoccurring themes. Three main themes were identified: (i) challenges when raising a grandchild with FASD, including kinship adoption struggles and intergenerational issues; (ii) worries about the future, including financial planning and health concerns; and (iii) rewards, such as shifts in priorities and the opportunity to raise a second generation. Grandparents raising their grandchildren with FASD face challenges and thus require specific supports so that they may adequately provide a safe and nurturing home environment for children with often challenging learning and social needs. 相似文献

Gender-Sexuality Alliances (GSAs), which are student-initiated school clubs for LGBTQ youth and allies, can reduce victimization for lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth. This preregistered study identified heterogeneous correlates of GSAs, based on data from an anonymous survey of LGBTQ adolescents aged 13–17 years living in the United States (N = 10,588). In line with the healthy context paradox (Pan et al. [Child Development, 92, 2021, and 1836]), the presence of a GSA exacerbated associations between LGBTQ-based victimization and depressive symptoms, lower self-esteem, and lower academic grades—particularly in transgender youth. Inclusive settings, such as GSAs, might prevent increasing disparities by including tailored strategies to monitor and support more vulnerable, victimized LGBTQ youth. 相似文献

In this paper, I study the production of academic research by economics departments and economists. Worldwide rankings are provided based on both citations and publications. These rankings reveal a dominant position of the United States in the production of economics literature. Over time, however, the extent of this dominance is decreasing. (JEL: A10, A14) 相似文献
