TL;DR: From this model, a working definition of different roles and attributes for forensic scientists is described which may offer greater clarity for both practitioners and users of forensic science.

TL;DR: The analyses of 738 soil and sediment samples taken during the investigation of 20 forensic cases are combined in a database for retrospective comparisons and the technique suggests possibilities, in some circumstances, that significant interpretations can be achieved at different orders of classification.

TL;DR: The goal is to explicitly describe the logical mechanisms that underpin the inference of identity of source in forensic science and to propose a concrete methodology for the forensic individualisation from biometric data.

TL;DR: It was found that a general rule existed that it was the material type rather than the particulate type that was the major controlling factor in the persistence of particles.

TL;DR: An approach based on a compromise--based on an extended likelihood ratio--that may combine the merits of logic without overstepping acceptable bounds for the forensic scientist in the presentation of evidence is suggested.

TL;DR: This research demonstrates that almost one in five items recovered from fire scenes yielded fingerprint ridge detail following normal development treatments.

TL;DR: The GC-MS method developed for the impurity profiling of illicit MDMA tablets was found to be practical, robust, relatively easy to perform, highly discriminative and yielding good chromatography.

TL;DR: This study demonstrates that PBS can be used for the extraction of spermatozoa and cells from swabs and that PBS does not affect subsequent DNA profiling.

TL;DR: It is demonstrated for the first time that positive results can be obtained from certain washing powders as well as other household products that are suitable for the detection of amylase.

TL;DR: Fibres from 160 samples of denim articles in current use were examined by microspectrophotometry to determine whether either indigo derivative dye, or other dyes, had been used instead of the traditional indigo.

TL;DR: A pilot study of the total foreign fibre population on a small number of garments found that knowledge should assist the forensic fibre analyst when using a Bayesian framework to interpret fibre cases is added.

TL;DR: This paper addresses the question of how many Monte Carlo iterations are required to get sufficient accuracy in the estimates of sampling error, and demonstrates the flexibility of the Bayesian HPD over other methods.

TL;DR: The kind of data collected by Crime Scene Examiners (CSEs) is assessed, and whether this collection constitutes a scientific process, and the balance of roles performed by the CSE is examined.

TL;DR: Results from this study lead to the conclusion that the NaOH wash solution is ideally suited for soot removal to reveal latent and blood-contaminated marks both within the laboratory and at crime scenes.

TL;DR: It was found that the exclusion of light significantly prolonged the useful life of standards, with aqueous solutions of both psilocin and psilocybin being stable over a period of seven days.

TL;DR: A system developed for automatically sorting a database of images of outsole patterns in response to a reference image has translational and rotational invariance and does not have to correspond with the spatial positioning of the shoeprint images of the database.

TL;DR: The problem of drawing inferences within a legal framework when a person is a suspect for two separate offences is considered and the evidence can be conveniently classified into three categories that concern: the first crime only; the second crimeonly; and evidence that relates to similarities between the two crimes.

TL;DR: The case was received in which a woman suspected that she had been sexually assaulted or raped while unconscious, with a request to establish whether a profile suitable for the National DNA Database could be obtained.

TL;DR: In recent years there seems to be an ever increasing number of conferences, seminars and working group meetings all bidding for our attendance as discussed by the authors, which can be a challenge as we try to justify the costs and juggle what is probably our most valuable commodity, time, while still attempting to actually have a life outside of work.

TL;DR: Change Magazine as mentioned in this paper has a new look and more varied but focused content and features, with a more varied and focused content, features, and content, and a new feature set.

TL;DR: In this paper, the authors look at the nature and amount of information available about individuals online and compare different types of information about individuals, including social media profiles and online biographies.

TL;DR: The difficulties in presenting and communicating often complex scientific information to a lay audience are not new as discussed by the authors and neither are the rules by which we must operate within a legal or judicial framework, after all legal systems of one form or another were in existence long before forensic science was applied to criminal or civil investigations.
