Forensic document examination and algorithmic handwriting analysis of Judahite biblical period inscriptions reveal significant literacy level.

Arad is a well preserved desert fort on the southern frontier of the biblical kingdom of Judah. Excavation of the site yielded over 100 Hebrew ostraca (ink inscriptions on potsherds) dated to ca. 600 BCE, the eve of Nebuchadnezzar's destruction of Jerusalem. Due to the site's isolation, small size and texts that were written in a short time span, the Arad corpus holds important keys to understanding dissemination of literacy in Judah. Here we present the handwriting analysis of 18 Arad inscriptions, including more than 150 pair-wise assessments of writer's identity. The examination was performed by two new algorithmic handwriting analysis methods and independently by a professional forensic document examiner. To the best of our knowledge, no such large-scale pair-wise assessments of ancient documents by a forensic expert has previously been published. Comparison of forensic examination with algorithmic analysis is also unique. Our study demonstrates substantial agreement between the results of these independent methods of investigation. Remarkably, the forensic examination reveals a high probability of at least 12 writers within the analyzed corpus. This is a major increment over the previously published algorithmic estimations, which revealed 4-7 writers for the same assemblage. The high literacy rate detected within the small Arad stronghold, estimated (using broadly-accepted paleo-demographic coefficients) to have accommodated 20-30 soldiers, demonstrates widespread literacy in the late 7th century BCE Judahite military and administration apparatuses, with the ability to compose biblical texts during this period a possible by-product.

Vocal Features: From Voice Identification to Speech Recognition by Machine.

This article considers machine methods used in the collection, processing, and application of vocal recordings for speaker identification and speech recognition between 1908 and 1970. The first phonographic archives featured collections of "vocal portraits" that prompted international investigations into the essential features of human voices for individual identification. Visual records of speech later found the same applications, but as "voiceprint identification" via sound spectrography began to achieve legal and commercial success in the 1960s, the procedure attracted more widespread scientific attention, which ultimately discredited both its accuracy and its rationale. At the same time, spectrogram collections spurred a new application-speech recognition by machine. The changing status of the speech spectrogram, from a record of unique features of individual voices to a model of fundamental invariants in speech sounds, was rooted in the demands of automated processing and a corresponding shift from the sound archive to the acoustic database.

Forensic Identification in the Aftermath of Human Rights Crimes in Chile: A Decentered Computer History.

As computer historians extend the bounds of what constitutes computer history, they must also take care not to write histories that overstate the importance of these technologies. "Decentering" the computer in computer history provides a way for historians to study the role of computers in more domains without exaggerating their importance. Here I illustrate how the use of a computer system for forensic identification formed part of Chile's complicated history of truth, justice, and reconciliation in the aftermath of the Pinochet dictatorship. While computers are not, and should not be, the central focus of how we understand processes of truth and reconciliation in history, in this case they illuminate the dynamics of how those working within the Chilean government, including its justice system, have approached Chile's history of human rights abuses.

Insects and associated arthropods analyzed during medicolegal death investigations in Harris County, Texas, USA: January 2013- April 2016.

The application of insect and arthropod information to medicolegal death investigations is one of the more exacting applications of entomology. Historically limited to homicide investigations, the integration of full time forensic entomology services to the medical examiner's office in Harris County has opened up the opportunity to apply entomology to a wide variety of manner of death classifications and types of scenes to make observations on a number of different geographical and species-level trends in Harris County, Texas, USA. In this study, a retrospective analysis was made of 203 forensic entomology cases analyzed during the course of medicolegal death investigations performed by the Harris County Institute of Forensic Sciences in Houston, TX, USA from January 2013 through April 2016. These cases included all manner of death classifications, stages of decomposition and a variety of different scene types that were classified into decedents transported from the hospital (typically associated with myiasis or sting allergy; 3.0%), outdoor scenes (32.0%) or indoor scenes (65.0%). Ambient scene air temperature at the time scene investigation was the only significantly different factor observed between indoor and outdoor scenes with average indoor scene temperature being slightly cooler (25.2°C) than that observed outdoors (28.0°C). Relative humidity was not found to be significantly different between scene types. Most of the indoor scenes were classified as natural (43.3%) whereas most of the outdoor scenes were classified as homicides (12.3%). All other manner of death classifications came from both indoor and outdoor scenes. Several species were found to be significantly associated with indoor scenes as indicated by a binomial test, including Blaesoxipha plinthopyga (Wiedemann) (Diptera: Sarcophagidae), all Sarcophagidae (including B. plinthopyga), Megaselia scalaris Loew (Diptera: Phoridae), Synthesiomyia nudiseta Wulp (Diptera: Muscidae) and Lucilia cuprina (Wiedemann) (Diptera: Calliphoridae). The only species that was a significant indicator of an outdoor scene was Lucilia eximia (Wiedemann) (Diptera: Calliphoridae). All other insect species that were collected in five or more cases were collected from both indoor and outdoor scenes. A species list with month of collection and basic scene characteristics with the length of the estimated time of colonization is also presented. The data presented here provide valuable casework related species data for Harris County, TX and nearby areas on the Gulf Coast that can be used to compare to other climate regions with other species assemblages and to assist in identifying new species introductions to the area. This study also highlights the importance of potential sources of uncertainty in preparation and interpretation of forensic entomology reports from different scene types.

Parasites in Forensic Science: a historic perspective

Parasites show a great potential to Forensic Science. Forensic Science is the application of any science and methodology to the legal system. The forensic scientist collects and analyses the physical evidence and produce a report of the results to the court. A parasite is an organism that lives at the expense of another and they exist in any ecosystem. Parasites are the cause of many important diseases. The forensic scientists can use the parasites to identify a crime scene, to determine the murder weapon or simply identify an individual. The applications for parasites in the Forensic Science can be many and more studies should be made in Forensic Parasitology. The most important parasites in Forensic Science are helminths specifically schistosomes. Through history there are many cases where schistosomes were described in autopsies and it was related to the cause of death. Here we review the applications of parasites in Forensic Science and its importance to the forensic scientist.

Mycology in palaeoecology and forensic science.

Palynology (including mycology) is widely used in palaeoecological and bioarchaeological studies. Lake and mire sediments, soils, and the deposits accumulating in archaeological features, invariably contain plant and fungal remains, particularly pollen and spores. These serve as proxy indicators of ancient environmental conditions and events. Forensic palynology has been successfully employed in criminal investigations for more than two decades. In recent years, it has included fungal palynomorphs in profiling samples from crime scenes, and from exhibits obtained from suspects and victims. This contribution outlines the main features of palynology, and gives examples of case studies where fungal spores, pollen, and plant spores, have enhanced the interpretation of ancient landscapes and land-use, and provided pivotal intelligence, and probative evidence, in criminal investigations.

REWRITING ECOLOGICAL SUCCESSION HISTORY: DID CARRION ECOLOGISTS GET THERE FIRST?

Ecological succession is arguably the most enduring contribution of plant ecologists and its origins have never been contested. However, we show that French entomologist Pierre Mégnin, while collaborating with medical examiners in the late 1800s, advanced the first formal definition and testable mechanism of ecological succession. This discovery gave birth to the twin disciplines of carrion ecology and forensic entomology. As a novel case of multiple independent discovery, we chronicle how the disciplines of plant and carrion ecology (including forensic entomology) accumulated strikingly similar parallel histories and contributions. In the 1900s, the two groups diverged in methodology and purpose, with carrion ecologists and forensic entomologists focusing mostly on case reports and observational studies instead of hypothesis testing. Momentum is currently growing, however, to develop the ecological framework of forensic entomology and advance carrion ecology theory. Researchers are recognizing the potential of carcasses as subjects for testing not only succession mechanisms (without assuming space-for-time substitution), but also aggregation and coexistence models, diversity-ecosystem function relationships, and the dynamics of pulsed resources. By comparing the contributions of plant and carrion ecologists, we hope to stimulate future crossover research that leads to a general theory of ecological succession.

From paranoia querulans to vexatious litigants: a short study on madness between psychiatry and the law. Part 2.

The second part of this paper examines the history of querulous paranoia and vexatious litigation in the English-speaking countries from the nineteenth century to today. This study suggests that the lack of thorough research on querulous paranoia in these countries is due to a broad cultural, legal and medical context which has caused unreasonable complainants to be considered a purely legal, rather than a medical issue. To support this hypothesis, I analyse how legal steps have been taken throughout the English-speaking world since 1896 to keep the unreasonable complainants at bay, and I present reasons why medical measures have scarcely been adopted. However, I also submit evidence that this division of responsibilities between the judges and the psychiatrists has taken a new turn since the dawn of the twenty-first century.

Modern scientific evidence pertaining to criminal investigations in the Chosun dynasty era (1392-1897 A.C.E.) in Korea.

A guidebook detailing the process of forensic investigation was written in 1440 A.C.E. It outlines the fundamentals and details of each element of criminal investigation during the era of the Chosun dynasty in Korea. Because this old guidebook was written in terms of personal experience rather than on scientific basis, it includes many fallacies from the perspective of modern forensic science. However, the book describes methods to form a scientific basis for the experiments performed. We demonstrate the modern scientific basis for ancient methods to monitor trace amounts of blood and detect lethal arsenic poisoning from a postmortem examination as described in this old forensic guidebook. Traces of blood and arsenic poisoning were detected according to the respective color changes of brownish red, due to the reaction of ferric ions in blood with acetic ions of vinegar, and dark blue, due to the reaction of silver with arsenic sulfide.

Forensic entomology investigations from Doctor Marcel Leclercq (1924-2008): a review of cases from 1969 to 2005.

Dr. Marcel Leclercq was a pioneer in the field of forensic entomology. He has provided his knowledge of insect biology to many forensic cases, and most of them have found the way to publication. Most of the articles he has written were focused on individual cases, and despite the abundance of entomoforensic investigations he conducted, no synthesis has been published. This article summarizes 36 yr of forensic entomological investigations in temperate Europe, mainly in Belgium. Dr. Leclercq's work includes 132 entomological cases involving 141 human corpses found in various death scenes. Under certain conditions, insect specimens found at death scene can provide information on when (postmortem interval estimation), where and how a person died. More or less 100 insect species associated with a dead body have been identified by Dr. Leclercq.

Making space for criminalistics: Hans Gross and fin-de-siècle CSI.

This article explores the articulation of a novel forensic object-the 'crime scene'-and its corresponding expert-the investigating officer. Through a detailed engagement with the work of the late nineteenth-century Austrian jurist and criminalist Hans Gross, it analyses the dynamic and reflexive nature of this model of 'CSI', emphasising the material, physical, psychological and instrumental means through which the crime scene as a delineated space, and its investigator as a disciplined agent operating within it, jointly came into being. It has a further, historiographic, aim: to move away from the commonplace emphasis in histories of forensics on fin-de-siècle criminology and toward its comparatively under-explored contemporary, criminalistics. In so doing, it opens up new ways of thinking about the crime scene as a defining feature of our present-day forensic culture that recognise its historical contingency and the complex processes at work in its creation and development.

Forensic cultures in historical perspective: technologies of witness, testimony, judgment (and justice?).

This article explores the history of forensic science in terms of ideologies and institutions rather than developing technique. It presents an analytical framework for characterising forensic institutions and practices, past and present. That framework highlights the distinct issues of means of witness, accredited testimony, and the reaching of juridical decisions. The article applies the framework by comparing four forensic 'formations,' (or 'cultures') which have been prominent at various times and places in the western world from the early modern period onward: these are the central European heritage of the Caroline code, a eugenically-oriented forensic enterprise of late nineteenth-century America, the forensic perspective in nineteenth-century British India, and the representation of forensic certainty in contemporary American popular culture. The article concludes with a critique of what seems an increasingly common expectation: that forensic science evolves independently of legal institutions, and can ultimately displace them.

The rise and fall of forensic hypnosis.

This paper examines the fortunes of the controversial use of hypnosis to 'enhance' autobiographical memories in postwar America. From the 1950s through the early 1980s, hypnosis became increasingly popular as a means to exhume information thought to be buried within the mind. This practice was encouraged by lay understandings of memory drawn from a material culture full of new recording devices (motion pictures, tape and then video recorders); and during the years when the practice was becoming most popular and accepted, academic psychologists developed a contrary, reconstructive, account of memory that was put to use in a series of battles meant to put an end to hypnotic recall. But popular commitment to the idea of permanent memory 'recordings' sustained the practice and the assumptions about memory and self that were associated with it, and in the face of a culture of academic psychology fully committed to the idea of 'reconstructive', malleable memory, a tidal wave of 'enhanced' memories swept America in the late 1980s and 1990s, in the so-called 'memory wars'. These, in turn, provoked academic psychologists to research the claims and counter claims central to the memory wars. The paper will also make an argument about the importance of lay knowledge in the psychological sciences explored in this paper: that popular psychological beliefs played a significant, even formative role in defining the nature of forensic psychological expertise, and also the framing of elite academic psychological research.
