Age and lineup type differences in the own-race bias

The own-race bias (ORB) suggests that recognition for faces of one's own race is superior to recognition of other-race faces. A popular explanation for the ORB is amount of interracial contact, which may have cohort effects for older and younger adults. We compared White younger and older adults on the ORB utilizing a hybrid facial recognition and full diagnostic lineup (i.e., simultaneous and sequential target absent and target present lineups) paradigm. Both younger and older adults demonstrated an ORB. Signal detection estimates suggest younger adults compared to older adults have better discrimination accuracy for own-race over other-race faces. Interracial contact did not explain recognition for younger adults, but was related to a shift in response criterion for older adults.     

Modelling the buried human body environment in upland climes using three contrasting field sites

Despite an increasing literature on the decomposition of human remains, whether buried or exposed, it is important to recognise the role of specific microenvironments which can either trigger or delay the rate of decomposition. Recent casework in Northern England involving buried and partially buried human remains has demonstrated a need for a more detailed understanding of the effect of contrasting site conditions on cadaver decomposition and on the microenvironment created within the grave itself. Pigs (Sus scrofa) were used as body analogues in three inter-related taphonomy experiments to examine differential decomposition of buried human remains. They were buried at three contrasting field sites (pasture, moorland, and deciduous woodland) within a 15 km radius of the University of Bradford, West Yorkshire, UK. Changes to the buried body and the effect of these changes on hair and associated death-scene textile materials were monitored as was the microenvironment of the grave. At recovery, 6, 12 and 24 months post-burial, the extent of soft tissue decomposition was recorded and samples of fat and soil were collected for gas chromatography mass spectrometry (GCMS) analysis. The results of these studies demonstrated that (1) soil conditions at these three burial sites has a marked effect on the condition of the buried body but even within a single site variation can occur; (2) the process of soft tissue decomposition modifies the localised burial microenvironment in terms of microbiological load, pH, moisture and changes in redox status. These observations have widespread application for the investigation of clandestine burial and time since deposition, and in understanding changes within the burial microenvironment that may impact on biomaterials such as hair and other associated death scene materials.     

SUPERVISED CHILD ACCESS

Responding to demand from separated parents and courts for ways to manage intractable child access disputes, services that supervise parent-child contacts are emerging across the United States and Canada. This article traces the evolution of this new social service, describes programs, and presents practical issues.     

The Importance of Establishing Reliability and Validity of Assessment Instruments for Mental Health Problems: an Example from Somali Children and Adolescents Living in Three Refugee Camps in Ethiopia

Assessing mental health problems cross-culturally for children exposed to war and violence presents a number of unique challenges. One of the most important issues is the lack of validated symptom measures to assess these problems. The present study sought to evaluate the psychometric properties of two measures to assess mental health problems: the Achenbach Youth Self-Report and the Child Posttraumatic Stress Disorder Symptom Scale. We conducted a validity study in three refugee camps in Eastern Ethiopia in the outskirts of Jijiga, the capital of the Somali region. A total of 147 child and caregiver pairs were assessed, and scores obtained were submitted to rigorous psychometric evaluation. Excellent internal consistency reliability was obtained for symptom measures for children and their caregivers. Validation of study instruments based on local case definitions was obtained for the caregivers but not consistently for the children. Sensitivity and specificity of study measures were generally low, indicating that these scales would not perform adequately as screening instruments. Combined test–retest and inter-rater reliability was low for all scales. This study illustrates the need for validation and testing of existing measures cross-culturally. Methodological implications for future cross-cultural research studies in low- and middle-income countries are discussed.
