Child-to-parent violence occurs when children engage in violent behaviour towards family members; the principal victim is often the mother. The risk assessment instruments used to identify the risk and protective factors in youth offenders who perpetrate child-to-parent violence are not specific to this type of offense. This study aims to describe the child-to-parent violence group in relation to the risk and protective factors they present in comparison with the group of young people who committed an assault offence. The sample for this study consists of two groups of youth offenders. The first group committed child-to-parent violence, and the second group has committed a violent crime against individuals to whom they are not related. Young people who commit child-to-parent violence have higher scores on the SAVRY risk factors and lower scores on the SAVRY protective factor than young people who have committed an assault offence. The results reveal the importance of identifying the risk and protective factors presented by youth offenders who commit child-to-parent violence in order to create specific intervention programs for the needs and strengths presented by this group of young people.

In the vulnerability analysis of System on Chips, memory hierarchy is considered among the most valuable element to protect against information theft. Many first-order side-channel attacks have been reported on all its components from the main memory to the CPU registers. In this context, memory hierarchy encryption is widely used to ensure data confidentiality. Yet, this solution suffers from both memory and area overhead along with performance losses (timing delays), which is especially critical for cache memories that already occupy a large part of the spatial footprint of a processor. In this paper, we propose a secure and lightweight scheme to ensure the data confidentiality through the whole memory hierarchy. This is done by masking the data in cache memories with a lightweight mask generator that provides masks at each clock cycle without having to store them. Only 8-bit Initialization Vectors are stored for each mask value to enable further recomputation of the masks. The overall security of the masking scheme is assessed through a mutual information estimation that helped evaluate the minimum number of attack traces needed to succeed a profiling side-channel attack to 592 K traces in the attacking phase, which provides an acceptable security level in an analysis where an example of Signal to Noise Ratio of 0.02 is taken. The lightweight aspect of the generator has been confirmed by a hardware implementation that led to resource utilization of 400 LUTs. Full article

Instruments that assess recidivism risk in young people are used widely in the sphere of juvenile justice worldwide. Traditionally, research has focused on the study of risk factors presented by young offenders, and how these relate to criminal recidivism. In present-day research, protective factors have also come into their own, having proven to encourage non-recidivism in young offenders. This paper presents a study carried out with 594 young offenders. The instrument used for assessing risk of recidivism in young offenders was the Structured Assessment of Violence Risk in Youth (SAVRY). In the results found here, one can observe how the young offenders who did not reoffend presented a greater level of protective factors than the repeating offenders. The youths with a prior arrest record scored higher in the risk domains than the reoffenders without a prior arrest record. The case of young repeat offenders who already had an arrest record represents a high-risk profile, or a profile of a criminal career. Crimes committed by young people can be isolated incidents in their life. In most youths, criminal behavior does not persist beyond legal age. Protective factors prove to be important in juvenile justice when planning an individualized intervention for the young offender. Full article

The research aims to identify if the accumulation of protective and/or risk factors might predict the risk of recidivism in juvenile delinquents and determine the relative weight of both types of factors in the predictions themselves. The risk of criminal recidivism was assessed with the Structured Assessment of Violence Risk in Youth—SAVRY—instrument based on a sample of 192 Adolescents in Conflict with the Law—ACLs—held in juvenile detention centers in the Valencian Community (Spain). The results show that protective variables have greater relative consistency than risk variables when assessing recidivism risk in ACLs. The paper’s findings enable advances in the identification of antisocial behavior patterns using positive variables, and this in turn involves modifying any intervention proposals made by professionals of juvenile justice because psycho-socio-educational processes can now be dealt with on the basis of the ACLs’ potentialities (protective factors) rather than their deficiencies (risk factors) alone.
