Cognitive-behavioural treatment of anger intensity among offenders with intellectual disabilities

Abstract: Background Aggressive behaviour has been identified as a significant problem amongst people with intellectual disabilities living in institutional settings. Anger is a key activator of aggressive behaviour, as well as being an important element of clinical distress related to adverse life experiences. There is some evidence for the value of cognitive–behavioural treatments for anger problems with people having intellectual disabilities. No controlled studies of anger treatment involving intellectually disabled offenders living in secure settings have been conducted to date. A pilot study of an elaborated anger treatment protocol for this client population was undertaken, comparing the specialised anger treatment with routine care. Methods Detained men with intellectual disabilities and histories of offending were allocated to specially modified cognitive–behavioural anger treatment (n = 9) or to routine care waiting-list control (n = 10) conditions. Eighteen sessions of individual treatment were delivered over a period of 12 weeks. Treatment outcome was evaluated by participants' self-report of anger intensity to an inventory of provocations and by staff-ratings of the anger attributes of participants' ward behaviour. Results Participants' reported anger intensity was significantly lower following the anger treatment, compared to the routine care wait-list condition. There were largely no treatment condition effects in staff-rated anger. Limited evidence for the effectiveness of anger treatment was provided by the staff ratings of participant behaviour post-treatment. Conclusions Detained offenders with intellectual disabilities can benefit from intensive individual cognitive–behavioural anger treatment. Further research is required to examine the mechanisms for change and their sustainability.

Vibration and buckling analysis of functionally graded sandwich beams by a new higher-order shear deformation theory

Abstract: This paper proposes a new higher-order shear deformation theory for buckling and free vibration analysis of isotropic and functionally graded (FG) sandwich beams. The present theory accounts a new hyperbolic distribution of transverse shear stress and satisfies the traction free boundary conditions. Equations of motion are derived from Lagrange's equations. Analytical solutions are presented for the isotropic and FG sandwich beams with various boundary conditions. Numerical results for natural frequencies and critical buckling loads obtained using the present theory are compared with those obtained using the higher and first-order shear deformation beam theories. Effects of the boundary conditions, power-law index, span-to-depth ratio and skin-core-skin thickness ratios on the critical buckling loads and natural frequencies of the FG beams are discussed.

Sediment transport and siltation of brown trout (Salmo trutta L.) spawning gravels in chalk streams

Abstract: Deposition rates of fine sediment into brown trout spawning gravels were measured at monthly intervals for a period of one year in a small channel of the River Test, Hampshire. Data were also collected on stream discharge, water depth, flow velocity and suspended sediment concentrations. Deposition rates followed a seasonal pattern and were maximal during periods of high discharge in the late winter/early spring when suspended sediment concentrations were high. The material deposited in the spawning gravels included silts and fine sands (<250 μm) that were transported in suspension and coarser fragments of low density tufalike material that were transported as bed load. The ecological implications of fine sediment deposition for salmonid egg survival in chalk streams are considered.
