Regulator of G-protein signaling 4 (RGS4) gene is associated with schizophrenia in Irish high density families

The regulator of the G-protein signaling 4 (RGS4) gene was shown to have a different expression pattern in schizophrenia patients in a microarray study. A family-based study subsequently implicated the association of this gene with schizophrenia. We replicated the study with our sample from the Irish Study of High Density Schizophrenia Families (ISHDSF). Single marker transmission disequilibrium tests (TDT) for the four core SNPs showed modest association for SNP 18 (using a narrow diagnostic approach with FBAT P = 0.044; with PDT P = 0.0073) and a trend for SNP 4 (with FBAT P = 0.1098; with PDT P = 0.0249). For SNP 1 and 7, alleles overtransmitted to affected subjects were the same as previously reported. Haplotype analyses suggested that haplotype G-G-G for SNP1-4-18, which is the most abundant haplotype (42.3%) in the Irish families, was associated with the disease (narrow diagnosis, FBAT P = 0.0061, PDT P = 0.0498). This was the same haplotype implicated in the original study. While P values were not corrected for multiple testing because of the clear prior hypothesis, these results could be interpreted as supporting evidence for the association between RGS4 and schizophrenia.

Evaluation of genetic substructure in the Irish Study of High-Density Schizophrenia Families

The presence of genetic substructure has the potential to diminish the chances of detecting a linkage signal. Using a Markov chain Monte Carlo procedure developed by Pritchard and colleagues and implemented in the program STRUCTURE, we evaluated the evidence for genetic substructure using genotypes from 37 microsatellite markers in affected individuals selected at random from 263 multiplex families in the Irish Study of High-Density Schizophrenia Families. We found no evidence for the presence of genetic substructure in this sample.

Mother's Narratives of Trauma: An exploratory study of how mothers' narrate the impact of trauma on their families

This study explored the narratives of 10 mothers whose families had been impacted by potentially traumatising events. The study was set in the context of Post-Traumatic Stress Disorder (PTSD), a relatively narrow psychiatric construct, which currently dominates much professional discourse and practice in traumatology, but references literature that provides a theoretical rationale for a broader approach. Narrative Interviewing methodology was employed and mothers of families referred to a specialist clinical service were interviewed prior to professional therapeutic intervention. The 10 mothers' narratives were analysed thematically via a rigorous process involving two independent analysts and the data organised into an evolving theoretical framework of themes and supra-themes. As hypothesised, PTSD symptomatology constituted a small proportion of the mothers' narratives (6.2%). The major components of the narratives included family and relational distress (35.7%), non-pathological individual distress (24.4%), resilience (16.7%) and a prior history of adversity (16.6%). Although exploratory in nature, the results of this study are sufficiently strong to warrant further investigation and raise tentative questions regarding the appropriateness of many existing therapeutic services for people impacted by trauma.

For vulnerable families, continued postnatal care, provided by family midwives, is associated with improved maternal care and parent–child relationship

This paper illustrates how findings from two related studies can enhance nursing and midwifery practice through the evaluation of the effectiveness of a family midwives (FMs) intervention.

Weaving behavior into feature models for embedded system families

Product Line software Engineering depends on capturing the commonality and variability within a family of products, typically using feature modeling, and using this information to evolve a generic reference architecture for the family. For embedded systems, possible variability in hardware and operating system platforms is an added complication. The design process can be facilitated by first exploring the behavior associated with features. In this paper we outline a bidirectional feature modeling scheme that supports the capture of commonality and variability in the platform environment as well as within the required software. Additionally, 'behavior' associated with features can be included in the overall model. This is achieved by integrating the UCM path notation in a way that exploits UCM's static and dynamic stubs to capture behavioral variability and link it to the feature model structure. The resulting model is a richer source of information to support the architecture development process.

Relational architecture description language for software families

Software Product-Line Engineering has emerged in recent years, as an important strategy for maximising reuse within the context of a family of related products. In current approaches to software product-lines, there is general agreement that the definition of a reference-architecture for the product-line is an important step in the software engineering process. In this paper we introduce ADLARS, a new form of architecture Description language that places emphasis on the capture of architectural relationships. ADLARS is designed for use within a product-line engineering process. The language supports both the definition of architectural structure, and of important architectural relationships. In particular it supports capture of the relationships between product features, component and task architectures, interfaces and parameter requirements.

Child Maltreatment and High Risk Families: Protecting children and young people

Most child maltreatment occurs within the context of high risk families. There are ethical, economic and ecological reasons why physical abuse in such families should be a major concern. Physical abuse is a significant issue throughout the UK. Yet, while neglect and other forms of abuse are receiving focused attention, physical abuse may languish under the misconceptions that it is no longer a problem, is addressed elsewhere, or is just too overwhelming an issue.
The physical abuse of children can involve regular, violent treatment at the hands of parents or carers over a number of years. Its physical effects may last for days and may result in actual physical injury. It is not accidental. Although physical abuse can occur in any family, it is prevalent in particular sectors of society, where families may be vulnerable to a combination of complex risk factors such as domestic abuse, alcohol and drug (mis)use, and mental health issues. These factors are present in 34% of Serious Case Reviews (SCRs).
The authors provide an increased understanding of risk, analysis, impact, learning and the current landscape of service delivery in relation to the physical abuse of children living in high risk families for professional, postgraduate and policy-making audiences.
