E-simulations for the purpose of training forensic (investigative) interviewers

One of the most critical issues facing investigative organisations is how best to administer effective practice opportunities in investigative interviewing on a global scale. Interviewer evaluation research across the world has highlighted inadequacies in the adherence to and maintenance of best-practice interview approaches, and insufficient opportunities for practice and feedback are the major reasons attributed by experts for poor interviewer competency. “Unreal Interviewing: Virtual Forensic Interviewing of a Child” (an e-simulation created at Deakin University, Australia) was developed as a way to ‘expand the reach’ of trainers in the investigative interviewing area. The simulation enables trainers to provide ongoing professional development for forensic interviewers in dispersed work environments, without the financial burden on organisations of extracting large numbers of professionals from the workplace to the classroom. This chapter provides readers with: an overview of the key stages involved in the development of Unreal Interviewing and the education and technical decisions that needed to be made; and a review of the application of “Unreal Interviewing” in the training and continuing professional development of trainees in their workplace.

Using relationship-building in event profiling for digital forensic investigations

In a forensic investigation, computer profiling is used to capture evidence and to examine events surrounding a crime. A rapid increase in the last few years in the volume of data needing examination has led to an urgent need for automation of profiling. In this paper, we present an efficient, automated event profiling approach to a forensic investigation for a computer system and its activity over a fixed time period. While research in this area has adopted a number of methods, we extend and adapt work of Marrington et al. based on a simple relational model. Our work differs from theirs in a number of ways: our object set (files, applications etc.) can be enlarged or diminished repeatedly during the analysis; the transitive relation between objects is used sparingly in our work as it tends to increase the set of objects requiring investigative attention; our objective is to reduce the volume of data to be analyzed rather than extending it. We present a substantial case study to illuminate the theory presented here. The case study also illustrates how a simple visual representation of the analysis could be used to assist a forensic team.

The nature of supervision in forensic psychology : some observations and recommendations

Purpose – Supervision is often regarded as an important aspect of forensic psychological practice and yet little evidence exists to support the idea that supervised practice leads to better outcomes for either clients or organisations. This paper seeks to discuss some of the aims of supervision in relation to the needs of forensic psychologists, such that practice in this area can be developed further.

Design/methodology/approach – The current published literature on the nature of forensic supervision is reviewed and discussed.

Findings – A number of different models of supervision have been proposed and supervisory experiences can vary markedly according to both the individuals involved and the setting in which the work is conducted. There is a need to develop specialist models of supervision for those who work in forensic settings. Further research is needed to establish an evidence-base for supervisory practices.

Originality/value – There has been very little previous consideration of the nature of post-qualification forensic supervision despite the need, and in some cases requirement, that forensic practitioners receive supervision. This paper discusses some of those issues that are considered important to effective supervision in the forensic setting.

An alternative for the extraction and storage of DNA from insects in forensic entomology

An important area of recent research in forensic entomology has been the use of insect DNA to provide identification of insects for fast and accurate estimation of time since death. This requires DNA to be extracted efficiently and in a state suitable for use in molecular procedures, and then stored on a long-term basis. In this study, Whatman FTA™ cards were tested for use with the Calliphoridae (Diptera). In particular, testing examined their ability to effectively extract DNA from specimens, and store and provide DNA template in a suitable condition for amplification using the polymerase chain reaction (PCR). The cards provided DNA that was able to be amplified from a variety of life stages, and thus appears to be of sufficient quality and quantity for use in subsequent procedures. FTA cards therefore appear suitable for use with calliphorids, and provide a new method of extraction that is simple and efficient and allows for storage and transportation without refrigeration, consequently simplifying the handling of DNA in forensic entomological cases.

Towards a sustainable assessment strategy for digital forensic education and training

In this paper, we show the development and application of a sustainable assessment strategy as an implementation of effective learning for a computer crime and digital forensics unit. The unit is undertaken by undergraduate students as part of an Information Technology Security course at Deakin University. Over a five year period the teaching team has made continuous improvements to the delivery of material and content taking informal student feedback and Faculty review into careful consideration. In addition formal student evaluation of the unit has been extremely positive. As part of reflective teaching practice the teaching team derived a map of the relationship between learning objectives, learning activities, the assessment and the unit outcomes to verify what has led to the favorable student experience and its impact on learning process in order to repeat this strategy for other tertiary courses.

Hypothesis generation and testing in event profiling for digital forensic investigations

The need for an automated approach to forensic digital investigation has been recognized for some years, and several authors have developed frameworks in this direction. The aim of this paper is to assist the forensic investigator with the generation and testing of hypotheses in the analysis phase. In doing so, the authors present a new architecture which facilitates the move to automation of the investigative process; this new architecture draws together several important components of the literature on question and answer methodologies including the concept of ‘pivot’ word and sentence ranking. Their architecture is supported by a detailed case study demonstrating its practicality.

Competing ethical paradigms in forensic psychiatry and forensic psychology: commentary for a special section of legal and criminological psychology

In her paper Gwen Adshead (2013) identifies the principle of respect for justice as the foundation for ethical practice in forensic psychiatry. This commentary discusses how forensic psychologists have approached a key aspect of the justice principle, the ethical imperative to promote the welfare of the individual client. The approaches of the psychiatric and psychological professions are compared and the role of psychologists as allied health professionals working in the forensic setting considered.

Assessing students’ attitudes toward forensic science: collecting an expert consensus

We report the development of an affective domain instrument for the assessment of undergraduate students’ attitudes toward forensic science. Assessment of attitudes of the respondents is important to understand mediating factors in student motivation and ultimately success in the discipline. The instrument was developed using an iterative process based on responses from an expert panel of Australian forensic science educators to an array of forensic science and teaching related topics, and refined using further feedback from the panel on more specific items. The layout of the instrument, with regard to both the wording and placement of items, was developed with regular test takers (i.e., students) in mind and through the application of basic psychometric principles. The engagement of forensic science colleagues across Australia has resulted in an outcome that could provide a source of credible and relevant evidence of student attitudes toward forensic science.
