Autopsy Findings in Botulinum Toxin Poisoning

Abstract: In the United States, foodborne botulism is most commonly associated with home‐canned food products. Between 1950 and 2005, 405 separate outbreaks of botulism were reported to the Centers for Disease Control and Prevention (CDC). Approximately 8% of these outbreaks were attributed to commercially produced canned food products. Overall, 5–10% of persons ingesting botulinum toxin die. Few reports exist pertaining to autopsy findings in cases of foodborne botulism. Here, we report the autopsy findings of a man who died after a prolonged illness caused by botulinum toxin exposure likely attributable to a commercially prepared food source. Despite extensive testing, our histopathologic findings were nonspecific. We therefore conclude that the forensic pathologist must become familiar with the neurotoxicity syndrome associated with this illness. Maintaining vigilance for botulism by carefully reviewing the decedent’s clinical history will aid in the early identification and control of outbreaks, either foodborne or terrorism‐related.     

Research note: The founders and survivors project

This paper describes the multidisciplinary project Founders and Survivors: Australian Life Courses in Historical Context. Individual life courses, families and generations through the nineteenth and twentieth centuries are being reconstituted from a wide range of data including convict records; birth, death and marriage registrations; and World War I service records. The project will result in a longitudinal study of Australian settlement, the long-run effects of forced labour and emigration on health and survival, family formation, intergenerational morbidity and mortality, and social and geographic mobility.     

Intraobserver Error in Macromorphoscopic Trait Data, ,

As part of a much larger investigation into the use of macromorphoscopic trait data by forensic anthropologists to estimate ancestry from unidentified skeletal remains, we conducted a fourteen‐year (2002–2016) intraobserver error study. Motivated by the development of a large macromorphoscopic database―which will potentially utilize data collected in 2002―quantification of observer error, the impact of technological improvements in macromorphoscopic trait data collection and observer experience is necessary. To maximize comparisons between the two samples, ten macromorphoscopic traits were assessed. Results revealed three patterns of error relating to observer experience, the introduction of new technologies, and error inherent in the method. Overall, this study found the effect of error on macromorphoscopic trait analysis could be predicted and did not significantly impact their utility.     

Effect of Aging and Surface Interactions on the Diffusion of Endogenous Compounds in Latent Fingerprints Studied by Mass Spectrometry Imaging,

The ability to determine the age of fingerprints would be immeasurably beneficial in criminal investigations. We explore the possibility of determining the age of fingerprints by analyzing various compounds as they diffuse from the ridges to the valleys of fingerprints using matrix‐assisted laser desorption/ionization mass spectrometry imaging. The diffusion of two classes of endogenous fingerprint compounds, fatty acids and triacylglycerols (TGs), was studied in fresh and aged fingerprints on four surfaces. We expected higher molecular weight TGs would diffuse slower than fatty acids and allow us to determine the age of older fingerprints. However, we found interactions between endogenous compounds and the surface have a much stronger impact on diffusion than molecular weight. For example, diffusion of TGs is faster on hydrophilic plain glass or partially hydrophilic stainless steel surfaces, than on a hydrophobic Rain‐x treated surface. This result further complicates utilizing a diffusion model to age fingerprints.     

The Modern Compound Bow

Bows and arrows are ancient weapons that have risen and fallen as the preeminent armaments used by man. Because of the ubiquity of firearms, fatalities from archery injuries in the United States have radically declined. However, when deaths involving this weapon do present themselves, the paucity of reference materials can be a hurdle for forensic pathologists and other forensic scientists. This article will provide a brief history of the origins of the bow and the inception of the compound bow. Comparing and contrasting the structures comprising a traditional bow to those of the modern compound bow will provide insight into how these components function in unison to propel arrows.     

Fear is a Disease: The Impact of Fear and Exposure to Infectious Disease on Correctional Officer Job Stress and Satisfaction

This study examined individual and work-level factors that impact job stress and satisfaction for correctional officers. Existing research has explored officer job stress and satisfaction, but very few studies have focused specifically on fear of contracting an infectious disease while at work (HIV/AIDS, hepatitis, and tuberculosis), and the impact fear of and exposure to infectious disease have on correctional officer job stress and satisfaction. Random sample data were collected from 2,999 male and female officers from across the state of Texas to assess job stress, satisfaction, personal safety, and exposure to infectious disease. Ordinary Least Squares analyses indicated that fear of disease was positively correlated with job stress, and inversely correlated with job satisfaction. Exposure to disease however, failed to yield any significant effects on job stress or satisfaction. Officers who felt that their supervisors were supportive of them on the job reported less stress and higher satisfaction levels, while perceived dangerousness of the job was positively correlated with job stress. These findings highlight the importance of supervisory support as well as continuous, in-depth education and training on infectious diseases for officers.     

Cautioning jurors regarding co-witness discussion: the impact of judicial warnings

Abstract

The research seeks to identify the most common problem areas and associated treatment needs of incarcerated and recently released offenders, to determine the importance of prison-based treatment and to assess the motivation of offenders towards treatment. Interviews were scheduled with representatives of three participant categories: drug-involved incarcerated offenders (n=18), recently released prisoners (n=15) and treatment staff members (n=18), resulting in 1971 statements. Using the qualitative software package WinMAX98, these expressions were categorized in a tree structure, after a codification process of the raw material. The results suggest that there is a difference in opinion between offenders and service providers with regard to the most important problems related to incarceration and re-entry. The findings further indicate that released offenders struggle more often than incarcerated offenders with problems concerning their psychological status. Therefore, the need for continuous through-care and aftercare is apparent, as is the necessity to assess the participants’ support expectancies and their individual needs. Motivating offenders to take part in (prison-based) treatment initiatives and aftercare is a major challenge, which can be accomplished by cooperation and partnerships between the criminal justice system and community-based treatment providers.     

The relationship between intelligence,memory and interrogative suggestibility in young offenders

Abstract

The study investigated the relationship between interrogative suggestibility and relevant cognitive factors as proposed by Gudjonsson and Clark (1986). The subjects were fifty-eight adolescent young offenders resident in a national children's centre with secure facilities. All were administered the Gudjonsson Suggestibility Scale and the Wechsler Intelligence Scale for Children. Interrogative suggestibility correlated negatively with intelligence and recall memory. Limited evidence of range effects was found for the relationship between intelligence and suggestibility, but not for the relationship between recall memory and suggestibility.     

Reconstructing and sequencing behaviours in multiple perpetrator rape

Abstract

Much of the existing knowledge base of multiple perpetrator rape (MPR) comes from studies undertaken more than 20 years ago, and thus fails to integrate contemporary perspectives on sexual violence. The current study used Grounded Theory methodology to construct a holistic model of MPR from 15 victim accounts. The model of multiple perpetrator rape (MMPR) included both the actions of the perpetrators and the reactions of the victim in a temporal sequence of 13 categories, 9 of which had sub-categories that allowed for individual differences. Broad themes of MPR were then explored using a total of 101 cases. Each case was coded in the 9 sub-categories where individual differences were allowed from the model. An associative analysis of these sub-categories was then performed using Smallest Space Analysis. Two dominant themes were displayed. The Manipulate theme included two perpetrators who offended sequentially and socialised with the victim. The Force theme did not involve any social interaction, as the force and teamwork of the group enabled the victim to be physically overpowered.
