The Integrated Psychosocial Model of Criminal Social Identity (IPM-CSI) explains the underlying reasons, i.e. risk factors, for the development of criminal social identity (CSI). Empirical research surrounding these risk factors is inconsistent in the measures and procedures used and the risk factors were mostly considered in isolation from one another. The main purpose of the paper was to review existing empirical studies elucidating correlates of CSI incorporated in the IPM-CSI and indicate further direction for research. A search in PubMed, PsychInfo, ERIC, Google Scholar, and the journal Child Development and Adolescent Studies was performed. Eleven studies exploring the correlates of CSI were identified and discussed herein. Studies indicated that there is potential for further expansion of the IPM-CSI to consider the consequences of CSI. Based on the present study results, a set of recommendations are provided for future research.
Current source inverters (CSI) is one of the widely used converter topology in medium voltage drive applications due to its simplicity, motor friendly waveforms and reliable short circuit protection. The current source inverters are usually fed by controlled current source rectifiers (CSR) with a large inductor to provide a constant supply current. A generalized control applicable for both CSI and CSR and their extension namely current source multilevel inverters (CSMLI) are dealt in this paper. As space vector pulse width modulation (SVPWM) features the advantages of flexible control, faster dynamic response, better DC utilization and easy digital implementation it is considered for this work. This paper generalizes SVPWM that could be applied for CSI, CSR and CSMLI. The intense computation involved in framing a generalized space vector control are discussed in detail. The algorithm includes determination of band, region, subregions and vectors. The algorithm is validated by simulation using MATLAB /SIMULINK for CSR 5, 7, 13 level CSMLI and for CSR fed CSI.
