This paper descirbes how ship weights are estimated. Detail is presented concerning relationships between existing weight data and the characteristics of a new design as it develops from completion of feasibility design through contract design. Margin requirements are also discussed. The weight estimating ratios and factors presented, while not directly associated with a specific ship type, cover the weight classification groups one would use in the design of a surface combatant. The purpose of this paper is to present the fundamentals of weight estimating to the ship design community. With this knowledge, ship design engineers and managers should be able to personally identify with the important parts they all play in creation of a credible weight estimate.

Purpose In the early 1970s, clinical evidence emerged documenting causal links between prenatal alcohol exposure (PAE) and children’s behaviors as observed by child welfare social workers (CWSWs). Unfortunately, fetal alcohol spectrum disorders (FASD) remain on the margins of public health priorities. The purpose of this study was to elicit the views of child welfare social workers when responding to case of or suspected FASD. Design/methodology/approach A sample (N = 18) of CWSWs, allied health professionals and foster parents were interviewed. Findings Findings indicate that social workers struggle with their statutory duty to plan safe care for children with or suspected of having FASD. Emergent themes include struggling with advocacy, professional devaluation and lack of procedural guidance. Practical implications Social workers need a clear pathway and FASD knowledge to guide their interventions and enhance their capacity to advocate for affected children. Originality/value An abundance of research documents the direct effect of PAE on physical, cognitive and behavioral outcomes. However, few studies focus on the critical interface of children with an FASD entering public care and the social workers responsible for planning their safe care. This study sought to document social workers’ response to this vulnerable cohort of children.

Purpose Child welfare services (CWSs) globally continue to absorb high rates of children living with or suspected of fetal alcohol spectrum disorder (FASD). Such high prevalence rates render CWS with major ethical and moral dilemmas of meeting complex needs. Currently, many jurisdictions are challenged by diagnostic capacity and cost implications of formal FASD diagnosis. This paper aims to recommend a screening protocol to address management gap between FASD initial presentation and formal diagnosis. Design/methodology/approach This is a follow-up paper from a grounded-theory study of a sample (N = 18) of child welfare social workers (CWSWs), allied health professionals and foster parents. A stepwise protocol was developed through systematical interpretation of the final data. Findings The application of a five-step screening protocol would greatly support CWSW in meeting the needs of children with suspected FASD. This CWSWs-led assessment model incorporates a clinical evaluation to exclude neurodevelopmental conditions caused by known genetic disorders, followed by behavioral and neurocognitive psychosocial assessments. Research limitations/implications This study had several limitations. Firstly, as a specific social work-based sample, it is not necessarily representative of the wider population of social workers globally due to different cultural responses to FASD in CWSs. The transferability of findings will have to be considered due to cultural variations concerning FASD. Practical implications By offering a management and nonlabeling approach, this five-step screening protocol offers a delineated pathway for CWSW and addresses the major professional frustrations while seeking to plan safe care for a child suspected of having FASD. Social implications The research offers a pragmatic low-cost to society to alleviate the mounting social and monetary implications of FASD. A large percentage of children impacted by prenatal alcohol exposure do not qualify under formal clinical diagnostic guidelines. Leaving these children without intervention is problematic. The recommendation of this study addresses this critical gap in services. The primary aim is to alleviate the burden on this cohort of vulnerable children by offering nonlabeling neurodevelopmental screening. Originality/value The direct implications of FASD and how it impacts CWS are well documented. However, few studies focus on the critical interface of FASD and the role of CWSW responsible for planning their safe care. This paper offers a novel pragmatic and functional multistep protocol to aid CWSW in this complex area of practice.
