Mobilities and Knowledge Transfer: Understanding the Contribution of Volunteer Stays to North–South Healthcare Partnerships

In this paper, I review recent literature on the relationship between human mobility and knowledge transfer processes, and apply some of the more theoretical ideas to an evaluation of the kinds of mobility in which UK participants engage in the context of North–South healthcare partnerships (HCPs). Much of the contemporary research on highly skilled mobility highlights the role that short stays and circular mobility play in knowledge transfer processes. I consider the value of short stays in the travel–mobility–migration continuum and the contribution they make to the transfer, translation and effectiveness of knowledge. Healthcare partnerships are best conceptualized as knowledge networks, with various forms of mobility (both physical and virtual) playing a critical role in network‐generation, evolution and impact. I outline the findings of two studies. The first is an evaluation of HCPs (Ackers and Porter, 2011) and the second an in‐depth ongoing evaluation of one HCP known as the Liverpool–Mulago Partnership or LMP¹ (Porter et al., 2011). The results raise questions about the relationship between the different types of mobility that participants in HCPs (predominantly professional volunteers) engage in, particularly the duration and repeated quality of stays, and knowledge transfer processes. Williams argues that “there are still major gaps in our understanding of the specific contribution of international migration to knowledge transfer, of the processes involved, and of the conditions that facilitate this” (2006 588). In this paper, I begin to close some of these gaps and advance our understanding of the relationship between different forms of mobility and knowledge transfer processes, in the hopes that this will build the evidence base supporting the contribution of North–South HCPs to the achievement of the Millennium Development Goals ² .     

‘Don't Make Us Talk!’: Listening to and Learning from Children and Young People Living with Parental Alcohol Problems

Given the common issues of secrecy, shame and stigma, we know very little about the lives of children affected by parental alcohol problems from their own perspectives. Thirty children and young people (aged between 9 and 20) chose to communicate about this sensitive issue as part of a Scottish qualitative study. This study reveals how children and young people have extensive knowledge about parental alcohol problems and can demonstrate considerable agency in choosing how to share this knowledge in a research setting. Developing a greater understanding of children's nuanced ways of communicating has implications for research, policy and practice.     

Bayesian modelling of effects of prenatal alcohol exposure on child cognition based on data from multiple cohorts

High levels of prenatal alcohol exposure (PAE) result in significant cognitive deficits in children, but the exact nature of the dose-response relationship is less well understood. To investigate this relationship, data were assembled from six longitudinal birth cohort studies examining the effects of PAE on cognitive outcomes from early school age through adolescence. Structural equation models (SEMs) are a natural approach to consider, because of the way they conceptualise multiple observed outcomes as relating to an underlying latent variable of interest, which can then be modelled as a function of exposure and other predictors of interest. However, conventional SEMs could not be fitted in this context because slightly different outcome measures were used in the six studies. In this paper we propose a multi-group Bayesian SEM that maps the unobserved cognition variable to a broad range of observed outcomes. The relation between these variables and PAE is then examined while controlling for potential confounders via propensity score adjustment. By examining different possible dose-response functions, the proposed framework is used to investigate whether there is a threshold PAE level that results in minimal cognitive deficit.     

Experience with a criterion for the classification of johnson distributions

We use simulation to investigate the choice of percentiles when using the criterion given by Bowman and Shenton (1989) to select between Johnson's SB and STJ distributions for a data set. We also look at the choice of a tolerance level in classifying distributions as Johnson's SL-     

Pseudo-likelihood inference for clustered binary data

The maximum likelihood procedure to estimate paraneters of a model has scveral attractive properties including the existence of the covariance matrix which yield asymptotic covariances: for a sample size N the asymptotics are in general of order 1/N. Here we give an asymptotic for the skewness of the distribution of the maximum likelihood estimator of a parameter; this is of order 1/ n2 and this expression is new. Applications relate to the parameters of (i) the Poisson, binomial, and normal density. (ii) the gamna density and (iii) the Beta debsity. Other application are being considered. The expression for the asymptotic skowness at one phase of the study tured out to be unusually complicated involving the asymptotic expressions for variance and bias. When these were identified a much simpler compact expression appeared which we now describe. The work is a much improved treatment of the subject described in Shenton and Bowman (Mariunm likelihood estimation in small samples, Griffin. 1977).     

‘I think I'm more free with them'—Conflict,Negotiation and Change in Intergenerational Relations in African Families Living in Britain

ABSTRACT

While the family is increasingly being recognised as pivotal to migration, there remain too few studies examining how migration impacts on intergenerational relationships. Although traditional intergenerational gaps are intensified by migration, arguably there has been an over-emphasis on the divisions between ‘traditional’ parents and ‘modern’ children at the expense of examining the ways in which both generations adapt. As Foner and Dreby [2011. “Relations Between the Generations in Immigrant Families.” Annual Review of Sociology 37: 545–564] stress, the reality of post-migration intergenerational relations is inevitably more complex, requiring the examination of both conflict and cooperation. This article contributes to this growing literature by discussing British data from comparative projects on intergenerational relations in African families (in Britain, France and South Africa). It argues that particular understandings can be gained from examining the adaptation of parents and parenting strategies post-migration and how the reconfiguration of family relations can contribute to settlement. By focusing on how both parent and child generations engage in conflict and negotiation to redefine their relationships and expectations, it offers insight into how families navigate and integrate the values of two cultures. In doing so, it argues that the reconfiguration of gender roles as a result of migration offers families the space to renegotiate their relationships and make choices about what they transmit to the next generation.
