The Effect of Soft Tissue on Temperature Estimation from Burnt Bone Using Fourier Transform Infrared Spectroscopy

This study investigated the effect of soft tissue and different exposure times on the prediction of burning temperatures of bone when using Fourier transform infrared spectroscopy (FTIR). Ovis aries rib bones were burnt at different temperatures and for varying time intervals. Results of a linear regression analysis indicated that burn temperatures can be predicted with a standard error of ±70°C from defleshed bone spectra. Exposure time does not have a significant impact on prediction accuracy. The presence of soft tissue has a significant impact on heat‐induced changes of the bone matrix in low (<300°C) as well as high temperatures (>800°C), slowing down combustion in the former and accelerating it in the latter (p < 0.05). At medium temperatures, no significant difference was noted. These results provide forensic investigators a new perspective with which to interpret the results of crystallinity measures derived from burnt bone.     

Walking the line: Specialized and standard probation officer perspectives on supervising probationers with serious mental illnesses

Specialized probation programs were developed to more effectively address the unique needs of probationers with serious mental illnesses. Probation officers are tasked with serving both law enforcement and rehabilitative functions, and officers play an important gatekeeper function in helping probationers with serious mental illnesses avoid long incarceration sentences. The purpose of this paper was to explore specialized and standard probation officers' work in supervising probationers with serious mental illnesses. Twenty-one probation officers (11 specialized and 10 standard) participated in semi-structured interviews. Qualitative analyses examined: 1 — beliefs on the relationship between mental illness and crime; 2 — purpose of specialized and standard probation units; and 3 — approaches to supervising probationers with serious mental illnesses. Implications for developing more effective probation supervision programs are discussed.     

The relationship between the Financial and industrial sector in the U. K. economy

The article attempts to specify the relationship between industrial and commercial activity and the financial system within the UK economy. It does this in two ways. In the first place through a discussion of the different forms and circuits of capital which designate of the important relationships and categories integrating the financial and the industrial sectors. Secondly it assesses the specific form of the circuit of finance capital within the UK economic formation and points to some of the implications of this for the proposals to take into public ownership the Commercial Banks and Insurance Companies.
