Child abuse, child protection and disabled children : a review of recent research

This paper reports the results of a scoping study which reviewed research about child abuse, child protection and disabled children published in academic journals between 1996 - 2009. The review was conducted using a five stage method for scoping studies. Several studies have revealed a strong association between disability and child maltreatment, indicating that disabled children are significantly more likely to experience abuse than their non-disabled peers. Those with particular impairments are at increased risk. There is evidence that the interaction of age, gender and/or socio-cultural factors with impairment results in different patterns of abuse to those found among non-disabled children although the reasons for this require further examination. It appears that therapeutic services and criminal justice systems often fail to take account of disabled children's needs and heightened vulnerability. In Britain, little is known about what happens to disabled children who have been abused and how well safeguarding services address their needs. Very few studies have sought disabled children's own accounts of abuse or safeguarding. Considerable development is required, at both policy and practice level, to ensure that disabled children's right to protection is upheld. The paper concludes by identifying a number of aspects of the topic requiring further investigation

Safer recruitment? protecting children, improving practice in residential child care

In the wake of a number of high-profile cases of the abuse of children and young people in residential child care, there have been repeated calls for the improvement of recruitment and selection of residential child care staff. This paper describes the findings from a survey, undertaken in 2005, of operational and human resource managers who have responsibility for the recruitment and selection of residential child care staff in the voluntary and statutory sectors in Scotland. This research was commissioned by the Scottish Executive to identify which elements of safer recruitment procedures had been implemented following the countrywide launch of a Toolkit for Safer Recruitment Practice in 2001. Research findings show that although local authorities were more likely than voluntary organisations to have gone some way toward implementing safer recruitment procedures, the recruitment process lacked rigour and commitment to safer procedures in some organisations. The article discusses the current barriers to the introduction of safer recruitment methods and proposes some possible solutions for the future

A Variational Approach to Monte Carlo Renormalization Group

We present a Monte Carlo method for computing the renormalized coupling constants and the critical exponents within renormalization theory. The scheme, which derives from a variational principle, overcomes critical slowing down, by means of a bias potential that renders the coarse grained variables uncorrelated. The 2D Ising model is used to illustrate the method.Comment: 4 pages, 3 figures, 1 tabl

An anomalous alloy: Y_x Si_{1-x}

We study via density functional-based molecular dynamics the structural and dynamical properties of the rare earth silicon amorphous alloy Y_xSi_{1-x} for x=0.093 and x=0.156. The Si network forms cavities in which a Y^{3+} cation is entrapped. Its electrons are transferred to the Si network and are located in the dangling bonds of the Si atoms that line the Y cavities. This leads to the presence of low coordinated Si atoms that can be described as monovalent or divalent anions. For x=0.156, the cavities touch each other and share Si atoms that have two dangling bonds. The vibrational spectrum is similar to that of amorphous Si. However, doping induces a shoulder at 70 cm^{-1} and a pronounced peak at 180 cm^{-1} due to low coordinated Si.Comment: 4 pages, 4 figure
