In this paper a finite series approximation involving Laguerre polynomials is derived for central and noncentral multivariate gamma distributions. It is shown that if one approximates the density of any k nonnegative continuous random variables by a finite series of Laguerre polynomials up to the (n1, …, nk)th degree, then all the mixed moments up to the order (n1, …, nk) of the approximated distribution equal to the mixed moments up to the same order of the random variables. Some numerical results are given for the bivariate central and noncentral multivariate gamma distributions to indicate the usefulness of the approximations. 相似文献

A qualitative study explored the perspectives and lived experiences of school-age children during COVID-19 using a child rights lens. Twenty children between the ages of 7 and 12 participated in open-ended, virtual interviews. Our hermeneutic analysis found children's right to play and education were severely compromised leaving children to navigate between two worlds: the adult world of public health restrictions and that of their childhood. Despite challenges and lost childhood opportunities, children emerged as competent social agents and responsible citizens. Planning for future pandemics should include policies and practices that balance public health needs with the protection of children's rights. 相似文献

This study examined whether the development of happy victimizing (HV) from early to middle childhood predicted prosocial and aggressive behaviors 3 years later. Participants included 150 children (50% female, Mage at study onset = 4.53 years) and their parents at four annual time points. At each time point, semi-structured interviews were conducted to assess children's emotional expectations after committing hypothetical transgressions. Child and parent reports of children's prosocial behaviors and aggression were provided at the beginning and end of the study. Children who experienced faster declines in HV reported higher prosocial behaviors 3 years later, controlling for initial levels of prosocial behaviors. Children who exhibited increases or lesser declines in HV reported higher aggression at the study end. The development of HV was not related significantly to parent reports of prosocial behaviors and aggression in middle childhood. Findings confirm theorizing on the normative developmental trajectory of HV and suggest that deviations in HV across early childhood may partially explain later behavioral adjustment. 相似文献

Guided by the integrative model, this study investigated the moderating effect of East Asian American youth-reported (N = 143) racial-ethnic socialization (RES) in the relationship between the youth's experiences of discrimination and internalization of the model minority myth. The results suggest that there was a significant interaction between youth's racial discrimination and youth-reported awareness of discrimination on youth's internalization of the model minority myth (b = 3.52, p < .05). No significant interaction effect emerged between racial discrimination and maintenance of heritage culture on internalization of model minority myth. The findings offer several contributions to inform research, family, and communities in understanding the ways caregivers respond to youth's racialized settings, which also contribute to youth's positive outcomes. 相似文献

Changes in the working, study and social lives of emerging adults due to the COVID-19 pandemic have led to greater need for external supports. Many who lived independently may have sought that support by returning to live with parents. This study identifies factors associated with returns made between 2019 and 2020. It describes supports needed and obtained, relationships between parents and their resident emerging adults and identifies correlates of poor coping and high psychological distress. Data from the Longitudinal Surveys of Australian Youth and the Longitudinal Study of Australian Children were used and showed half of the emerging adults who moved did so due to COVID-19 restrictions. Loss of work and increased need for emotional and financial support were key drivers of moves. Nineteen per cent who returned found spending more time with family difficult and over half did not have their support needs fully met, increasing their odds of poor coping at that time (OR = 2.9, 4.3, respectively) and subsequent psychological distress (OR = 6.0). Families were an important source of support but could not necessarily mitigate all challenges; for some emerging adults, returning to live with parents gave rise to additional difficulties which negatively affected mental health. 相似文献
