Application of plant DNA markers in forensic botany: genetic comparison of Quercus evidence leaves to crime scene trees using microsatellites

As highly polymorphic DNA markers become increasingly available for a wide range of plant and animal species, there will be increasing opportunities for applications to forensic investigations. To date, however, relatively few studies have reported using DNA profiles of non-human species to place suspects at or near crime scenes. Here we describe an investigation of a double homicide of a female and her near-term fetus. Leaf material taken from a suspect's vehicle was identified to be that of sand live oak, Quercus geminata, the same tree species that occurred near a shallow grave where the victims were found. Quercus-specific DNA microsatellites were used to genotype both dried and fresh material from trees located near the burial site and from the material taken from the suspect's car. Samples from the local population of Q. geminata were also collected and genotyped in order to demonstrate that genetic variation at four microsatellite loci was sufficient to assign leaves to an individual tree with high statistical certainty. The cumulative average probability of identity for these four loci was 2.06x10(-6). DNA was successfully obtained from the dried leaf material although PCR amplification was more difficult than amplification of DNA from fresh leaves. The DNA profiles of the dried leaves from the suspect's car did not match those of the trees near the crime scene. Although this investigation did not provide evidence that could be used against the suspect, it does demonstrate the potential for plant microsatellite markers providing physical evidence that links plant materials to live plants at or near crime scenes.     

Assessing engagement skills in public child welfare using OSCE: a pilot study

A two-station (scenario) Objective Structured Clinical Examination (OSCE) was developed and tested for validity and reliability for assessing social work engagement skills in public child welfare. The simulated scenario was designed to allow for demonstration of skill with an involuntary adolescent and parent presenting as resistant. Independent raters assessed participants comprised of BSW students, MSW students, and experienced public child protection social workers (n = 17, station one, n = 16 station two). Scales demonstrated high internal consistency, inter-rater reliability, and initial discriminate groups validity. Findings suggest a promising approach for directly assessing social worker skill in engagement of clients. Implications for use of OSCE in child welfare are discussed.     

A Multidisciplinary Approach to Detecting and Responding to Elder Mistreatment: Creating a University-Community Partnership

As the aging population grows, the problem of elder mistreatment is escalating. Cases of elder mistreatment are anticipated to increase further as the—baby boomers age and the number of elderly individuals living and receiving care at home increases (Stiegel 2006; Kennedy 2005; Meeks-Sjostrom 2004). While there has been increasing attention placed on understanding the dynamic of elder mistreatment, advancement of public policy and scholarly work has been hampered due to the fact that much of this work occurs in disciplinary silos. This paper spotlights one example in which university scholars from various disciplines partnered with social service providers, legal professionals, and healthcare educators in the community to enhance the development of a sustainable comprehensive elder justice network.
