Geomatic techniques in forensic science: A review

The purpose of this review paper is to highlight various geomatic techniques that crime scene reconstructionists or forensic practitioners can use to document different kinds of scenes, highlighting the advantages, disadvantages, and when best to use each technology. This paper explores geomatic techniques such as a total station, photogrammetry, laser scanners and structured light scanners and how they can be used to reconstruct crime scenes. The goal of this paper is not to discredit manual methods, as they are long standing and reliable, but instead to shed light on alternative methods that may produce equally or more accurate results with a more visually appealing final product. It is important for law enforcement and forensic professionals to understand the advantages and disadvantages of each technique, knowing when certain techniques should be used (and when they should not), and being able to revert to traditional methods if required.

The Accountability Priorities of Australian Parliamentarians

Managerialist reforms to the public service, as part of the drive for improved efficiency and effectiveness, sought to reorient the accountability priorities of parliamentarians away from a supposedly excessive concern with process and results and more towards results (outputs and outcomes). To what extent, if any, have the accountability priorities of parliamentarians changed over the last two decades? Content analysis of a sample of estimates committee hearings dealing with six departments over three selected years (1986, 1992 and 2003) reveals a marked increase in attention to outputs and a correspondingly decreased focus on inputs (with little change in concern for process), thus confirming a managerialist trend. At the same time, Senators' explicit references to departments' budget documentation and annual reports fell away noticeably with the introduction of the outcomes and outputs framework which is therefore failing their accountability needs.     

Disaster documentation: improving medical information-sharing in sudden-onset disaster scenarios

Abstract

This study investigates clinical practitioners’ use of medical documentation during sudden-onset disasters in order to better understand how we can improve practice. Thirteen participants, representing nine nationalities and six clinical disciplines (with the collective working experience of at least 15 different organisations providing disaster response), underwent semi-structured interviews using an inductive approach based in grounded theory. The initial codes and themes were analysed over four coding rounds and developed into selective codes. The findings suggest that documentation is overwhelmingly de-prioritised in disasters due to competing demands; there is little incentive to complete documentation at an organisational or government level; practitioners acknowledge the importance of and need for adequate documentation; paper documentation still has its place whilst electronic approaches have both benefits and drawbacks; and disasters require bespoke documentation solutions. Development of the emergency medical team (EMT) ‘data management’ role within EMTs may be one way to focus teams on key areas of improvement.     

Forms of fettering: application forms and the exercise of discretion in the welfare state

ABSTRACT

Application forms are often the compulsory interface between citizens and their social rights. Applicants for support must navigate the questions, checklists and blank spaces in often long, detailed documents to assert their social entitlements. Given their ubiquity and the central role they play in the administration of the welfare state, it is perhaps surprising that they have been neglected in favour of a focus on other documentation, principally policy and guidance. This paper argues that the non-fettering ground of review – a principle whose jurisprudence is tied to the design and use of policy – also engages application forms. Through an analysis of 271 application forms used to administer the localised Discretionary Housing Payment scheme in England, three examples of their fettering potential are provided: the imposition of exhaustive criteria; requiring the applicant to self-classify or disclose irrelevant considerations; and constraining responses through tied evidential requirements. By arguing that the non-fettering ground should not limit itself to one kind of document (policy) when administrators are so reliant on another (application forms), the paper’s broader agenda is to argue that principles of good administration should apply to all documentation used to administer social entitlement.

Photographic Image Comparison of Vegetation

Images and videos are common types of evidence in crime scene investigations and laboratory analysis. Images may be taken by the suspect and/or by crime scene investigators and may serve as crucial elements in forensic laboratory analysis. Forensic photographic image comparison is the process of comparing one or more objects or persons in photographs/images when at least one image is known to be related to a crime. The forensic examiner usually compares the images in order to determine whether or not an association between the exhibits in the images can be made. This paper proposes an extension to the currently prevalent photographic image examination method. The extension introduces comparison of landscape and vegetation over time. It is revealed that similarities between images may still be found between the period of time the suspect photograph was taken and the period the crime scene investigator took the photograph from the same area. In this case report, two suspects to be involved in growing a marijuana field were arrested by the police. The forensic experts were asked to examine images taken by the crime scene investigators and to compare them to the images found in the suspects’ phones. They then tried to determine whether the suspects could be linked to the specific locations. While applying techniques derived from morphological comparison methodologies, the plants at the scene provided significant additional information. A tree trunk, branches, and twigs on a hedge in the photographs revealed specific individual characteristics that led the examiner to reach a conclusive decision.     

Photographic comparison of surface topography as a viable solution when physical match is challenging

Physical matching methods are a family of well‐known methods that are utilized in order to determine whether two pieces of a tearable/breakable material used to be one object. When performing physical match of polymers, it is sometimes difficult to reach an unambiguous conclusion. This is due to various reasons. One is when the tear/fracture resides in an inaccessible or hidden‐from‐view region of the piece. Another is when the shape of the tear/fracture at the object's tear/fracture line is insufficient for deducing a complete match. Third is deficiency of material along this line. These are examples of processes where the line is affected so drastically, so that a match renders impossible. Specifically, when addressing elastic materials, the tear/fracture line may even be squashed. This may also be a reason for difficulty in performing a physical match. In this paper, a method is proposed where a match is alternatively achieved by means of photographic comparison of marks on the surface topography of the pieces‐in‐question. Comparisons of pairs of torn pieces of silicon rubber were made. The procedure involved photography of the surface topography the pieces. Then, the photographs were horizontally mirror‐flipped. Lastly, a comparison was made between two photographs: a photograph of one piece and a mirror‐flipped photograph of the opposite piece. The results show that after comparing the pieces to one another, only one unique pair turned out to be positively matched. Using the proposed method, not only the comparison is done by a more informative method (comparing to physical match), it is also more convenient, faster, less expensive, and technically simpler.     

Photographic Analyses Using Skin Detail of the Hand: A Methodology and Evaluation,

Skin features have been employed by law enforcement agencies for suspect and victim identification. Comparisons of hand have arisen in casework where images have been submitted where a face was not present but a hand was visible. This research utilizes a collection of 128 hands from employees of the U.S. Army Criminal Investigation Laboratory to examine the frequency and distribution of skin detail on the dorsal surface of the hand. To assess the location of features, the hand was segmented into 14 regions using readily discernible anatomical landmarks. Overall, 2618 pigmented lesions and 92 scars or injuries were documented. When comparing the regions with one another, Regions 1–10 had fewer pigmented lesions than Regions 11–14. There was no pattern to the distribution of scars throughout the regions. The findings presented a foundation for one possible method that may differentiate hands based on the frequency and distribution of such features.
