The suitability of using domestic pigs (Sus spp.) as human proxies in the geophysical detection of clandestine graves

Research in many forensic science fields commonly uses domestic pigs (Sus spp.) as proxies for human remains, due to their physiological and anatomical similarities, as well as being more readily available. Unfortunately, previous research, especially that which compares the decompositional process, has shown that pigs are not appropriate proxies for humans. To date, there has not been any published research that specifically addresses whether domestic pigs are adequate human proxies for the geophysical detection of clandestine graves. As such, the aim of this paper was to compare the geophysical responses of pig cadavers and human donor graves, in order to determine if pigs can indeed be used as adequate human proxies. To accomplish this, ground penetrating radar (GPR) and electrical resistivity tomography (ERT) responses on single and multiple pig cadaver graves were compared to single and multiple human donor graves, all of which are in known locations within the same geological environment. The results showed that under field conditions, both GPR and ERT were successful at observing human and pig burials, with no obvious differences between the detected geophysical responses. The results also showed that there were no differences in the geophysical responses of those who were clothed and unclothed. The similarity of the responses may reflect that the geophysical techniques can detect graves despite what their contents are. The study implications suggest that experimental studies in other soil and climate conditions can be easily replicated, benefiting law enforcement with missing persons cases.     

System management and compensatory parenting: Educational involvement after maternal incarceration

Research has demonstrated that paternal incarceration is associated with lower levels of educational involvement among fathers and primary caregivers, but little is known regarding caregiver educational involvement when mothers have been incarcerated. In this study, we present the first analysis of variation in school- and home-based educational involvement by maternal incarceration history, pairing survey and interview data to connect macro-level group differences with micro-level narratives of mothers’ involvement in their children's education. Our survey data demonstrate that children of ever-incarcerated mothers experience increased school-based educational involvement by their primary caregivers, regardless of whether the caregiver is the mother herself. Our interview data point to compensatory parenting as a key motivating factor in educational involvement, wherein a caregiver endeavors to “make up for” the child's history of maternal incarceration. Findings add to the literature demonstrating maternal incarceration as a distinct experience from both paternal incarceration and material disadvantage alone, and they suggest the need to explore the role of schools as potential points of productive institutional involvement for mothers with an incarceration history.     

Psychometric Properties of a Brief Instrument to Assess Perceptions of Injustice Associated with Debilitating Health and Mental Health Conditions

The present study examined the psychometric properties of a shortened and simplified version of the Injustice Experience Questionnaire (IEQ). The instructional set of the original IEQ was modified to make it better suited to the context of debilitating health and mental health conditions that do not necessarily arise as a result of injury. The number of items was reduced from 12 to 5, and the response scale was simplified. The Injustice Experiences Questionnaire – Short Form (IEQ-SF) was administered to individuals diagnosed with a chronic musculoskeletal (MSK) condition (N?=?88) or major depressive disorder (MDD) (N?=?87). The internal consistency of the IEQ-SF was acceptable. The IEQ-SF was significantly correlated with measures of pain severity, depressive symptom severity and disability in both samples. Individuals with MDD scored higher on the IEQ-SF than individuals with MSK. The IEQ-SF was shown to be sensitive to treatment-related reductions in perceived injustice. Preliminary analyses suggest that the IEQ-SF is a reliable and valid measure of disability-related injustice perceptions associated with debilitating health and mental health conditions.     

Factors associated with desistance from violence in prison: an exploratory study

Desistance from crime has been of increasing interest within criminal justice literature, but desistance from offending behaviour whilst in custodial environments has not yet been investigated. Violence within prison establishments continues to be a significant problem; therefore, this study investigated the factors that are associated with desistance from custodial violence in 63 UK Category C adult male prisoners with a record of violence in prison. Participants completed measures of eight social and subjective factors associated with desistance in community samples. Those who had desisted from prison violence for 12 months or more showed greater levels of pro-social attitudes, agency and resilience than those who persisted in violence. Agency independently predicted desistance and this was particularly the case for younger offenders. Internal shifts appeared to be supported by a positive work environment. It is concluded that in custody an internal shift in perspective is especially important for desistance, and that this can be supported by the social environment. Opportunities to intervene may be greater in younger prisoners. It is recommended that current initiatives in developing agency and positive social interaction, such as Psychologically Informed Planned Environments, are further developed.
