A procedure is developed for determining two-group linear discriminant classifiers that misclassify the fewest number of observations in the training sample. An experimental study confirms the value of this approach. 相似文献

Substance use during the perinatal period and while parenting can pose a significant risk to children's safety and well-being. Mothers who have experienced child maltreatment are more likely to use substances than mothers without a history of maltreatment. This study explores how child welfare social workers experience supporting young, maltreated mothers struggling with substance use to prevent the intergenerational transmission of child maltreatment. Semi-structured in-depth interviews were conducted with four social workers working with young mothers with a history of maltreatment and substance use. Interpretative Phenomenological Analysis revealed two themes: (1) grappling with system challenges and (2) supporting strategies for disrupting intergenerational transmission of child maltreatment. The results highlight the need for systemic changes around support for social workers who work with young mothers who use substances and have a history of maltreatment, and substance use treatment and mental health programs themselves. Mothers need access to prenatal programs that are trauma-informed, non-judgemental and that support participants' basic needs and parenting skills. 相似文献

Scheduling of traditional job shops in make-to-order systems has seen extensive research over the past three decades. In such systems, performance is often related to various job completion metrics such as average flow time, average lateness, etc. This paper examines a scheduling problem in a make-to-stock environment where individual job completion measures are irrelevant. In this case, customer orders are satisfied through on-hand inventory where customer service is more closely related to the manufacturer's ability to quickly satisfy demand. We consider the role of scheduling in reducing inventories and improving customer service in the context of a manufacturer who assembles several different products on a single assembly line. We develop scheduling rules for such a system and experimentally compare their performance to those typically used in such environments. Our results indicate that rules which consider the inventory position and demand forecast outperform traditional fixed cycle rules. 相似文献

Global research has shown that most young people who are care experienced are not prepared to transition to independent living at 18 years of age and require support into early adulthood. We used rigorous systematic methods to identify English-based peer reviewed and grey literature describing innovations relevant to care experienced young people as they transition into adulthood, with a focus upon lessons for their implementation and diffusion. We synthesised the evidence narratively and organise data linked to seven key areas important to the transition to adulthood: (1) Health and well-being; (2) relationships; (3) education and training; (4) employment; (5) participation in society; (6) accommodation; (7) other. Twenty-five papers met our inclusion criteria. This review has found that, whilst there are a broad spectrum of innovations taking place within the social care environment for care experienced young people to support their transition into adulthood, there exists limited insight into how best to support implementation and diffusion of evidence-based innovation. We drew upon the ‘Consolidated Framework for Implementation Research’, developed in the setting of clinical service delivery, to highlight challenges in implementing and diffusing evidence-based innovation for care experienced young people transitioning into adulthood. 相似文献
