A test statistic for weighted runs

A new test statistic based on runs of weighted deviations is introduced. Its use for observations sampled from independent normal distributions is worked out in detail. It supplements the classic χ² test which ignores the ordering of observations and provides additional sensitivity to local deviations from expectations. The exact distribution of the statistic in the non-parametric case is derived and an algorithm to compute p-values is presented. The computational complexity of the algorithm is derived employing a novel identity for integer partitions.

Longitudinal predictors of homelessness: findings from the National Longitudinal Survey of Youth-97

Homeless youth represent a vulnerable and understudied population. Little research has prospectively identified factors that may place youth at risk for experiencing homelessness. The current study utilizes data from the National Longitudinal Survey of Youth-97 (NLSY-97) to examine predictors of experiencing homelessness as a young adult (before age 25). The NLSY-97 includes a nationally representative sample of 8984 youth. Data were first collected from these youth when they were between the ages of 12 and 18 years. The current study examined whether individual and family risk factors reported during adolescence predict homelessness by the age of 25. The findings showed that multiple runaway episodes, nontraditional family structure, lower educational attainment, and parental work limitations due to health increased the risk of homelessness. A permissive parenting style and being Hispanic protected against homelessness. This study offers unique insight into risk and protective factors for youth homelessness and has important clinical implications.

输入强化在多模态PPT演示中的实现

输入是语言习得发生的基础和前提,在二语尤其是外语课堂教学环境下,语言输入信息需要予以强化,以便增加被感知、注意、理解和内化的可能性。多模态PPT演示可以凭借相关技术手段,在视觉、音响以及二者结合的诸模态中有效实现对输入信息的强化。
