Cruelty has often been understood as the result of incurable bad character by those able to distinguish right from wrong. Recent research suggests a way of thinking about it as a form of disability in which people are unable to learn empathy, cognitive social skills and associated behaviour, which qualifies it as a form of learning disability. It is suggested that accepting this classification opens up the possibility that selected interventions might be successful in enabling people to understand, practise and appreciate affiliative behaviour.

The purpose of this paper is to consider oxytocin as a treatment for children diagnosed with callous unemotional [CU] traits, emotion regulation and whether moral disability is a meaningful category.

The paper discusses the relationship between psychiatric diagnoses, moral opprobrium and disability in relation to emotion regulation and diagnoses of callous unemotional conduct disorder (CUCD) and psychopathy, together with current research on oxytocin in humans.

Diagnoses of callous unemotional traits and psychopathy are problematic as a result of inbuilt moral opprobrium, while treating CUCD with oxytocin to promote prosociality through mandating a moral feeling brain oversimplifies how this neuropeptide operates in humans.

Oxytocin is currently under trial as a treatment for behavioural variant fronto‐temporal dementia, where patients display symptoms similar to those diagnosed with CUCD. As genetic, environmental and ethnic factors affect oxytocin's effects in humans, caution is warranted before supporting its use to treat CUCD. Moreover, such use may represent a reductionist technofix compared with addressing socioeconomic factors promoting the manifestation of CU traits as an adaptation.

The purpose of this paper was development of patient-specific femoral prosthesis using rapid prototyping (RP), a part of additive manufacturing (AM) technology, and comparison of its merits or demerits over CNC machining route.

The customized femoral prosthesis was developed through computed tomography (CT)-3D CAD-RP-rapid tooling (RT)-investment casting (IC) route using a stereolithography apparatus (SLA-250) RP machine. A similar prosthesis was also developed through conventional CT-CAD-CAM-CNC, using RP models to check the fit before machining. The dimensional accuracy, surface finish, cost and time involvement were compared between these two routes.

In both the routes, RP had an important role in checking the fit. Through the conventional machining route, higher-dimensional accuracies and surface finish were achieved. On the contrary, RP route involved lesser time and cost, with rougher surface finish on the prosthesis surface and less internal shrinkage porosity. The rougher surface finish of the prosthesis is favourable for bone ingrowths after implantation and porosity reduce the effective stiffness of the prosthesis, leading to reduced stress shielding effect after implantation.

As there is no AM machine for direct fabrication of metallic component like laser engineered net shaping and electron beam melting in our Institute, the metallic prosthesis was developed through RP-RT-IC route using the SLA-250 machine.

The patient-specific prosthesis always provides better fit and favourable stress distribution, leading to longer life of the prosthesis. The described RP route can be followed to develop the customized prosthesis at lower price within the shortest time.

The described methodology of customized prosthesis development through the AM route and its advantages are applicable for development of any metallic prostheses.

Report on the professional online database industry. CSP International have produced a report called, The Professional Online Database Industry which traces the industry's evolution and trends. “As society has become increasingly information‐oriented, businesses have been forced to rely on online databases for fast electronic retrieval of information,” notes Michael Tyler, President of CSP International. “The growth of the online database industry has been one of the most dramatic economic success stories of recent years, especially in light of the 1980–82 recession.
