Electrophysiological Brain Responses of Six‐Month‐Old Low Risk Premature Infants

This study sought to examine the electrophysiological correlates of visual perceptual priming in a sample of low risk preterm infants. We compared the ERP data of 20 healthy preterm infants at the age of 6 months (corrected age: 4 months) to those of 20 six‐month‐old and 20 four‐month‐old full term infants. The comparison groups represented the preterm infants' chronological and corrected ages respectively. The results showed that the brain responses of the preterm infants at the age of 6 months, specifically the topography and the latency of the Nc component, are more similar to those of their corrected age peers than to those of the chronological age controls.     

Vacation-separations: Therapeutic implications and clinical management

The literature is scanty concerning the clinical management of vacation-separations despite their potential for promoting either regression or therapeutic gain associated with the separation. A survey of clinical social workers highlights the range of practice philosophy and experience related to this topic. Case examples illustrate work around typical separation issues. This analysis of the clinical management of vacation-separations is grounded in the context of attachment theory, timing considerations, and separationindividuation issues.     

'Your friends don't understand': Invisibility and unmet need in the lives of 'young carers'

This paper is based on a study of the experiences of people identified as ‘young carers’, commissioned by the National Assembly for Wales as part of a wider review of carers’ needs and services. Following a brief review of some of the previous research in this area, the paper reports key findings of the research, using the words of children and young people as much as possible. It then goes on to explore some of the wider implications of this and other research for the identification and support of ‘young carers’ and their families, and for the understanding of the needs and wishes of children and young people so defined. The paper concludes with an alternative definition of a ‘young carer’ and with some recommendations for professional practice, suggesting that the role of social work is crucial in this area of service.     

The Myth of Global Social Work: Double Standards and the Local-Global Divide

The push towards “global standards” in social work is part of a movement to generate uniformity, quality control, and benchmarking for professional education programs. It acts as a powerful vestige of modern institutions and professional associations to prescribe through processes of standardization, formalization, and technical specificity. In social work “global standards” attempt to create a fixed set of minimal requirements to which all professional programs should adhere. Standards are viewed along two dimensions: (i) as a necessity due to the changes and scale of complexity in social work; and (ii) as a vehicle for importing dominant forms of knowledge, values, and skills. Those parties who enthusiastically underwrite attempts to construct “global standards” in fact create a powerful network of allies that undermine local or cultural differences and fail to reconcile them. Global standards in social work undercut indigenous skills and values and negate the expertise of professional judgement. They constitute an unnecessary and politically motivated intrusion in the world of social workers. Ultimately, standards such as these are an illegitimate, impersonal, and voluntary means of regulation. As such, global standards are inherently political because their construction and application formally regulates the local practices in which they become embedded. Over time, they modify the position of social work practitioners and alter relations of accountability to the standards themselves.     

The Haitian Revolution,History's New Frontier: State of the Scholarship and Archival Sources

Focusing on the era of the Haitian Revolution, this article analyses recent historiographical developments in both French and English. Though the field has made great strides in recent decades, it occasionally remains hampered by insufficient archival research, a parochial approach by US and French scholars, and linguistic fragmentation. The article also includes a survey of the main archival resources that are available to scholars in Europe, the Caribbean, and the USA.     

Smoothed Extreme Value Estimators of Non-Uniform Point Processes Boundaries with Application to Star-Shaped Supports Estimation

We address the problem of estimating the edge of a bounded set in ? ^d given a random set of points drawn from the interior. Our method is based on a transformation of estimators dedicated to uniform point processes and obtained by smoothing some of its bias corrected extreme points. An application to the estimation of star-shaped supports is presented.     

Social work,poverty, and child welfare interventions

The relationship between children's material circumstances and child abuse and neglect raises a series of questions for policy, practice, and practitioners. Children and families in poverty are significantly more likely to be the subject of state intervention. This article, based on a unique mixed‐methods study of social work interventions and the influence of poverty, highlights a narrative from practitioners that argues that, as many poor families do not harm their children, it is stigmatizing to discuss a link between poverty and child abuse and neglect. The data reveal that poverty has become invisible in practice, in part justified by avoiding stigma but also because of a lack of up‐to‐date research knowledge and investment by some social workers in an “underclass” discourse. We argue, in light of the evidence that poverty is a contributory factor in the risk of harm, that it is vital that social work engages with the evidence and in critical reflection about intervening in the context of poverty. We identify the need for fresh approaches to the harms children and families face in order to support practices that engage confidently with the consequences of poverty and deprivation.     

Estimation of extreme quantiles from heavy and light tailed distributions

In Gardes et al. (2011), a new family of distributions is introduced, depending on two parameters τ$\tau$ and θ$\theta$, which encompasses Pareto-type distributions as well as Weibull tail-distributions. Estimators for θ$\theta$ and extreme quantiles are also proposed, but they both depend on the unknown parameter τ$\tau$, making them useless in practical situations. In this paper, we propose an estimator of τ$\tau$ which is independent of θ$\theta$. Plugging our estimator of τ$\tau$ in the two previous ones allows us to estimate extreme quantiles from Pareto-type and Weibull tail-distributions in an unified way. The asymptotic distributions of our three new estimators are established and their efficiency is illustrated on a small simulation study and on a real data set.     

Neural mechanisms of language development in infancy

Understanding the neural processes underpinning individual differences in early language development is of increasing interest, as it is known to vary in typical development and to be quite heterogeneous in neurodevelopmental conditions. However, few studies to date have tested whether early brain measures are indicative of the developmental trajectory of language, as opposed to language outcomes at specific ages. We combined recordings from two longitudinal studies, including typically developing infants without a family history of autism, and infants with increased likelihood of developing autism (infant-siblings) (N = 191). Electroencephalograms (EEG) were recorded at 6 months, and behavioral assessments at 6, 12, 18, 24 and 36 months of age. Using a growth curve model, we tested whether absolute EEG spectral power at 6 months was associated with concurrent language abilities, and developmental change in language between 6 and 36 months. We found evidence of an association between 6-month alpha-band power and concurrent, but not developmental change in, expressive language ability in both infant-siblings and control infants. The observed association between 6-month alpha-band power and 6-month expressive language was not moderated by group status, suggesting some continuity in neural mechanisms.
