The tools to understand: community as co-researcher on culture-specific protective factors for Alaska Natives

A collaborative research process engaging Alaska Native communities in the study of protective factors in Alaska Native sobriety and the design of a preventative intervention using its findings is described. Study 1 was discovery oriented qualitative research whose objectives were identification of protective factors and development of a heuristic model. Study 2 involved quantitative survey methods to develop and test ameasure of protective factors identified by the qualitative study. Empirical data from these studies is presented, and the role of Alaska Native co-researchers who did not possess specialist research training is described in the design and implementation of the study, interpretation of findings, and design of the intervention model and tools. Benefits that emerged from co-researcher involvement in this process, to the community and to the co-researchers themselves, are described.     

A simple DNA extraction method for marijuana samples used in amplified fragment length polymorphism (AFLP) analysis

As a first step in developing a molecular method for the individualization of marijuana samples, we evaluated a plant DNA extraction kit. The QIAGEN plant DNeasy method uses a spin column format for recovery of DNA and is effective for obtaining high molecular weight DNA from leaf, flower (bud), and seed samples of marijuana. The average DNA yield was 125-500 ng per 100 milligrams of fresh plant tissue. The recovered DNA was of polymerase chain reaction (PCR) quality as measured by the ability to generate reproducible amplified fragment length polymorphism (AFLP) profiles. AFLP is a technique used to create a DNA profile for plant varieties and is being applied to marijuana samples by the authors to link growers and distributors of clonal material. The QIAGEN plant DNeasy method was simple, efficient, and reproducible for processing small quantities of marijuana into DNA.     

Deciphering indented impressions on plastic

The questioned document laboratory is often called upon to decipher writing that has been erased, obliterated, or that has faded. In cases like these, the original writing is no longer legible to the naked eye, but may be enhanced using various light sources. Certain remnants of the ink's components absorb into the substrate's fibers and can be visualized, usually as luminescence or absorbance. A case is described here that involved the theft of a credit card. An empty plastic credit card holder was found in the possession of a suspect, and as submitted for examination. Indented impressions could be discerned on its clear plastic window and presumably originated from the credit card that had been held in the envelope. These indented impressions were deciphered in the hope that they would reveal enough details from the credit card to establish a connection between the plastic envelope and the stolen credit card. With methods generally utilized in the toolmarks and materials laboratory and the photography laboratory of the Israel Police, most of the indented impressions on the plastic were deciphered and a connection between the plastic envelope and the stolen credit card was demonstrated.     

Tensions in private health insurance regulation

This article provides an analysis of the regulatory framework of Australian private health insurance linked to four major implicit regulatory objectives: promoting access to health insurance for consumers; promoting financial solvency and industry viability of registered health benefits organisations; promoting competition between registered health benefits organisations; and promoting accountability to consumers. Through an analysis of regulatory changes, case law and policy documents on the performance of the health insurance industry, it is argued that existing health insurance regulation exhibits inevitable tensions due to shifting and often conflicting government objectives about the role of private health insurance.     

Understanding rape and sexual assault: 20 years of progress and future directions

During the past 20 years, researchers have documented the widespread problem of rape in American society. Approximately one in four women are raped in their adult lifetime, which causes severe psychological distress and long-term physical health problems. The impact of sexual assault extends far beyond rape survivors as their family, friends, and significant others are also negatively affected. Moreover, those who help rape victims, such as rape victim advocates, therapists, as well as sexual assault researchers, can experience vicarious trauma. Future research and advocacy should focus on improving the community response to rape and the prevention of sexual assault.     

Development of a Computer‐Assisted Forensic Radiographic Identification Method Using the Lateral Cervical and Lumbar Spine

Medical examiners and coroners (ME/C) in the United States hold statutory responsibility to identify deceased individuals who fall under their jurisdiction. The computer‐assisted decedent identification (CADI) project was designed to modify software used in diagnosis and treatment of spinal injuries into a mathematically validated tool for ME/C identification of fleshed decedents. CADI software analyzes the shapes of targeted vertebral bodies imaged in an array of standard radiographs and quantifies the likelihood that any two of the radiographs contain matching vertebral bodies. Six validation tests measured the repeatability, reliability, and sensitivity of the method, and the effects of age, sex, and number of radiographs in array composition. CADI returned a 92–100% success rate in identifying the true matching pair of vertebrae within arrays of five to 30 radiographs. Further development of CADI is expected to produce a novel identification method for use in ME/C offices that is reliable, timely, and cost‐effective.     

Two Approaches,One Course: An Experience in Experiential Learning

In universities where experiential learning is not the norm, introducing this style of learning into undergraduate courses can be an intimidating process for both instructors and students. Instructors are often unsure of how to manage student experiences in the community, while a significant number of students react with skepticism toward this new type of course, as well as concern about their instructor's changing expectations for their performance. The following is a reflection of our first 2 years of teaching undergraduate courses from a distinctly experiential learning approach. Qualitative data is used to highlight the parallel learning processes that occurred over the semester, for students as well as for us as instructors. Our biggest challenges are explored in detail, and advice to instructors contemplating adapting an experiential approach to their own courses is presented.     

Two heads are better than one? How to effectively use two interviewers to elicit cues to deception

Background. We examined the effect of a second interviewer's demeanour on cues to deception. We predicted that a supportive demeanour would be the most beneficial for eliciting verbal cues to deceit, as it would encourage truth tellers, but not liars, to say more. In addition, we examined the extent to which interviewees deliberately made eye contact with the interviewers. Liars take their credibility less for granted than truth tellers, and therefore have a greater drive to be convincing. Liars are thus more likely to monitor the interviewer to determine if the interviewer appears to believe them. Method. Participants appeared before two interviewers: the first asked all the questions and the second remained silent. The second interviewer exhibited either a supportive, neutral, or a suspicious demeanour. Results. Truth tellers provided significantly more detail than liars, but only in the supportive second interviewer condition. The effect of a second interviewer's demeanour on detail was perhaps remarkable given that the interviewees hardly looked at the second interviewer (less than 10% of the time). Liars displayed more deliberate eye contact (with the first interviewer) than truth tellers did. Conclusions. A supportive second interviewer has a positive effect on interviewing. We discuss this finding in the wider contexts of investigative interviewing and interviewing to detect deception.
