Social Work with Children Affected by Domestic Violence: An Analysis of Policy and Practice Implications

The past decade has seen an increasing awareness of the emotional harm to children that can ensue from exposure to domestic violence. This article develops a framework for understanding social work responses, using an analysis of recent developments in British policy as an example. It is argued that to understand what these developments mean in practice we need to develop our analysis of the value perspectives underpinning them. Issues facing those charged with implementing these sometimes ambiguous policy and practice changes are discussed in three levels of intervention: the macro, the intermediate, and the 'street-level.' The article concludes by calling for closer collaboration between policy makers, practitioners and service users in the co-production of policy

Relational knowledge leadership and local economic development

This paper concerns the role of spatial leadership in the development of the knowledge-based economy. It is argued within academic and practitioner circles that leadership of knowledge networks requires a particular non-hierarchical style that is required to establish an ambience conducive to networking and knowledge sharing across boundaries. In this paper, we explore this hypothesis at both theoretical and empirical levels. Theoretically, we propose a conceptualization of relational knowledge leadership, which is ‘nomadic’ in its capacity to travel across multiple scales and cross sectoral, thematic and geographical boundaries. We have operationalized this type of relational knowledge leadership along four key features, derived from literatures on regional learning, organizational leadership and place leadership. Two empirical case studies are then presented, one from Birmingham in the UK and one from Eindhoven in the Netherlands, exploring how these features are expressed on the sub-national level. Also conclusions are drawn regarding the status of relational knowledge leadership. It is argued that the concept of relational knowledge leadership as viewed through our analytical lens does accord with the experience of leadership in the two cases presented. The cases also show that this style of leadership is confronted with three types of tensions that play through knowledge networking. Furthermore, it is argued that the cases exhibit this style of leadership to different degrees, reflecting their different cultural and political context

The V471A polymorphism in autophagy-related gene ATG7 modifies age at onset specifically in Italian Huntington disease patients

The cause of Huntington disease (HD) is a polyglutamine repeat expansion of more than 36 units in the huntingtin protein, which is inversely correlated with the age at onset of the disease. However, additional genetic factors are believed to modify the course and the age at onset of HD. Recently, we identified the V471A polymorphism in the autophagy-related gene ATG7, a key component of the autophagy pathway that plays an important role in HD pathogenesis, to be associated with the age at onset in a large group of European Huntington disease patients. To confirm this association in a second independent patient cohort, we analysed the ATG7 V471A polymorphism in additional 1,464 European HD patients of the “REGISTRY” cohort from the European Huntington Disease Network (EHDN). In the entire REGISTRY cohort we could not confirm a modifying effect of the ATG7 V471A polymorphism. However, analysing a modifying effect of ATG7 in these REGISTRY patients and in patients of our previous HD cohort according to their ethnic origin, we identified a significant effect of the ATG7 V471A polymorphism on the HD age at onset only in the Italian population (327 patients). In these Italian patients, the polymorphism is associated with a 6-years earlier disease onset and thus seems to have an aggravating effect. We could specify the role of ATG7 as a genetic modifier for HD particularly in the Italian population. This result affirms the modifying influence of the autophagic pathway on the course of HD, but also suggests population-specific modifying mechanisms in HD pathogenesis

Identification of genetic variants associated with Huntington's disease progression: a genome-wide association study

Background Huntington's disease is caused by a CAG repeat expansion in the huntingtin gene, HTT. Age at onset has been used as a quantitative phenotype in genetic analysis looking for Huntington's disease modifiers, but is hard to define and not always available. Therefore, we aimed to generate a novel measure of disease progression and to identify genetic markers associated with this progression measure. Methods We generated a progression score on the basis of principal component analysis of prospectively acquired longitudinal changes in motor, cognitive, and imaging measures in the 218 indivduals in the TRACK-HD cohort of Huntington's disease gene mutation carriers (data collected 2008–11). We generated a parallel progression score using data from 1773 previously genotyped participants from the European Huntington's Disease Network REGISTRY study of Huntington's disease mutation carriers (data collected 2003–13). We did a genome-wide association analyses in terms of progression for 216 TRACK-HD participants and 1773 REGISTRY participants, then a meta-analysis of these results was undertaken. Findings Longitudinal motor, cognitive, and imaging scores were correlated with each other in TRACK-HD participants, justifying use of a single, cross-domain measure of disease progression in both studies. The TRACK-HD and REGISTRY progression measures were correlated with each other (r=0·674), and with age at onset (TRACK-HD, r=0·315; REGISTRY, r=0·234). The meta-analysis of progression in TRACK-HD and REGISTRY gave a genome-wide significant signal (p=1·12 × 10−10) on chromosome 5 spanning three genes: MSH3, DHFR, and MTRNR2L2. The genes in this locus were associated with progression in TRACK-HD (MSH3 p=2·94 × 10−8 DHFR p=8·37 × 10−7 MTRNR2L2 p=2·15 × 10−9) and to a lesser extent in REGISTRY (MSH3 p=9·36 × 10−4 DHFR p=8·45 × 10−4 MTRNR2L2 p=1·20 × 10−3). The lead single nucleotide polymorphism (SNP) in TRACK-HD (rs557874766) was genome-wide significant in the meta-analysis (p=1·58 × 10−8), and encodes an aminoacid change (Pro67Ala) in MSH3. In TRACK-HD, each copy of the minor allele at this SNP was associated with a 0·4 units per year (95% CI 0·16–0·66) reduction in the rate of change of the Unified Huntington's Disease Rating Scale (UHDRS) Total Motor Score, and a reduction of 0·12 units per year (95% CI 0·06–0·18) in the rate of change of UHDRS Total Functional Capacity score. These associations remained significant after adjusting for age of onset. Interpretation The multidomain progression measure in TRACK-HD was associated with a functional variant that was genome-wide significant in our meta-analysis. The association in only 216 participants implies that the progression measure is a sensitive reflection of disease burden, that the effect size at this locus is large, or both. Knockout of Msh3 reduces somatic expansion in Huntington's disease mouse models, suggesting this mechanism as an area for future therapeutic investigation

Monad Translating Inductive and Coinductive Types

We show that the call-by-name monad translation of simply typed lambda calculus extended with sum and product types extends to special and general inductive and coinductive types so that its crucial property of preserving typings and - and commuting reductions is maintained. Speci c similar-purpose translations such as CPS translations follow from the general monad translations by specialization for appropriate concrete monads

Trusting emergence: some experiences of learning about integrated catchment science with the Environment Agency of England and Wales

The changing context of managing water in the European Union poses a fundamental and largely unaddressed question: are current scientific practices and scientific explanations able to meet the demands of doing effective integrated catchment management? This paper presents findings from 2 years of co-researching with scientists responsible for developing the Integrated Catchment Science Strategy within the Environment Agency, the main environmental regulatory body for England and Wales. The use of a co-researching approach using systems thinking and practice to enable social learning created, where none existed, a common conceptual framing of purpose and an incipient community of practice (CoP). Three key insights emerge: (1) integration of catchment sciences is possible at the level of policy objectives; (2) a shift in language and practice is required towards Integrated Catchment Managing to describe and enact the sets of purposeful activities and interactions among multiple stakeholders; (3) institutional and organizational constraints exist which limit the potential of CoPs to act in more innovative ways and develop more integrated and adaptive science-policy. Our findings confirm the need to develop learning processes which pay attention to the context, stakeholders, the key changes that are required in particular catchments and, most important of all, the epistemological perspective(s) of those involved in managing catchments

Reframing water governance praxis: does reflection on metaphors have a role?

Action for adaptation is needed in the face of anthropogenic climate change. The record of adaptation in the field of freshwater governance is poor to date, as it is apparently constrained by operational frameworks. Analyses based on the Contemporary Theory of Metaphor can reveal underlying, often institutionally reified, operational frameworks. We present a desktop metaphor mapping study of one UK and one Australian water management planning document. This mapping demonstrates the potential of metaphor analysis, with further methodological and praxis development, to support the new ways of thinking and acting that are needed to challenge deeply held social and cultural norms of linear, rather than systemic, causality. We suggest that metaphor has the potential to help practitioners expose and examine reified operational frameworks and practices, and to change those that hinder adaptive and systemic praxis
