Forensic Features of Lethal Late‐Presenting Diaphragmatic Hernias

Diaphragmatic defects are a relatively common and benign finding in adults which may be congenital or secondarily acquired. The case files at Forensic Sciences South Australia were reviewed over a 10‐year period from July 2005 to June 2015 for all adult (>17 years) cases in which diaphragmatic hernias were identified at postmortem examination that had either caused or contributed to death. Five cases were found: age range 49–90 years (average 67.2 years); male:female ratio 2:3. Herniated organs included the stomach (N = 3), small (N = 3) and large intestines (N = 2). Mechanisms of death involved lung compression with respiratory failure and/or mediastinal shift, and vascular compromise with gastric or intestinal infarction and/or perforation. Diaphragmatic hernias may not be identified until the time of autopsy and may be quite complex entities to evaluate due to a lack of clinical history and to difficulties in determining their origin and possible contributions to mechanisms of death.     

Pathological Features of Fatal Crocodile Attacks in Northern Australia, 2005–2014

Eleven deaths from crocodile attacks in the Northern Territory, Australia were reviewed. The male:female ratio was 8:3; age range—10–62 years, average 29.4 years. Four children were included (one boy and three girls, aged 10, 11, and two at 12 years), and there were seven aboriginal victims (64%). The attacks were witnessed in eight cases with the victims swimming in freshwater N = 5, standing on a river bank N = 1, fishing in fresh water N = 1, or diving in the sea N = 1. At autopsy, several distinct patterns of injury were observed ranging from complete traumatic disruption of the body with only incomplete remains for examination (N = 5), to crushing of the head with fractures of the skull (N = 4), crushing of the chest with fractures of the ribs and sternum (N = 2), and avulsion of limbs (N = 4). In one case, there was decapitation. Autopsy evaluations were complicated by decomposition and loss of body parts.     

The Corpus Callosum and Forensic Issues—An Overview

The corpus callosum is a large central white matter tract that connects the right and left cerebral hemispheres. It permits placental mammals to have a more sophisticated interhemispheric integration of sensory cortices and allows communication between cortical and subcortical neurons. Search of the literature and the pathology archives at The University of Adelaide was undertaken to identify lesions and injuries within the corpus callosum that may have forensic significance. These include developmental/congenital lesions with agenesis/dysgenesis, vascular malformations, and lipomas; inherited syndromes such as neurofibromatosis; and acquired lesions involving trauma, neoplasia, demyelination, vascular conditions, infections, fat embolism, aging/dementia, and the effects of toxins. The finding of lesions within the corpus callosum should initiate careful examination of the adjacent brain and other organ systems for related phenomena as this may shed some light on the nature of the underlying condition, and also help to determine whether there are any forensic implications.     

The Role of Interface Shape on the Impact Characteristics and Cranial Fracture Patterns Using the Immature Porcine Head Model, ,

The forensic literature suggests that when adolescents fall onto edged and pointed surfaces, depressed fractures can occur at low energy levels. This study documents impact biomechanics and fracture characteristics of infant porcine skulls dropped onto flat, curved, edged, and focal surfaces. Results showed that the energy needed for fracture initiation was nearly four times higher against a flat surface than against the other surfaces. While characteristic measures of fracture such as number and length of fractures did not vary with impact surface shape, the fracture patterns did depend on impact surface shape. While experimental impacts against the flat surface produced linear fractures initiating at sutural boundaries peripheral to the point of impact (POI), more focal impacts produced depressed fractures initiating at the POI. The study supported case‐based forensic literature suggesting cranial fracture patterns depend on impact surface shape and that fracture initiation energy is lower for more focal impacts.     

Appayya’s Vedānta and Nīlakaṇṭha’s Vedāntakataka

The seventeenth century author Nīlaka??ha Caturdhara wrote several works criticising the Vedāntic theology of the sixteenth century author, Appayya Dīk?ita. In one of these works, the Vedāntakataka, Nīlaka??ha picks out two doctrines for criticism: that the liberated soul becomes the Lord (ī?varabhāvāpatti), and that souls thus liberated remain the Lord until all other souls are liberated (sarvamukti). These doctrines appear both in Appayya’s Advaitin and in his ?ivādvaitin writings. They appear to be ones to which Appayya was committed. They raise theological and conceptual problems, however, both in themselves as doctrines, and as part of nondual Vedāntic teaching. A study of the Vedāntakataka reveals those features of Appayya’s Vedānta that Advaitins in Banaras in the century after his life considered to be anomalous, and illuminates aspects of the context in which his ideas developed and circulated.     

Is <Emphasis Type="Italic">Viveka</Emphasis> a Unique <Emphasis Type="Italic">Pramāṇa</Emphasis> in the <Emphasis Type="Italic">Vivekacūḍāmaṇi</Emphasis>?

This is an enquiry based on the Vivekacū?āma?i (VC), the primary focus of which is to present viveka (discrimination) along with its three catalysts, namely, ?ruti, tarka, and anubhava as the unique pramā?a of Ultimate Knowledge. This paper discusses the significance of the six popular pramā?as of Advaita Vedānta (AV) and reiterates that as far as AV is concerned epistemologically those pramā?as have merely a provisional value (vyāvahārika). In accordance with the purport of VC this paper argues that ?ruti and tarka, culminating in anubhava (trans-empirical insight sans experience) are blind in themselves and are enthusiastically carried forward by viveka (discrimination) for the attainment of the final realisation. This paper concludes that viveka, along with its three catalysts namely, ?ruti, tarka, and anubhava is the sole pramā?a of the trans-empirical experiential knowledge of Brahman.     

Exploring the Effect of Exposure to Short-Term Solitary Confinement Among Violent Prison Inmates

Objectives

This study tracked the behavior of male inmates housed in the general inmate populations of 70 different prison units from a large southern state. Each of the inmates studied engaged in violent misconduct at least once during the first 2 years of incarceration (n = 3,808). The goal of the study was to isolate the effect of exposure to short-term solitary confinement (SC) as a punishment for their initial act of violent behavior on the occurrence and timing of subsequent misconduct.

Methods

This study relied upon archival longitudinal data and employed a multilevel counterfactual research design (propensity score matching) that involved tests for group differences, event history analyses, and trajectory analyses.

Results

The results suggest that exposure to short-term solitary confinement as a punishment for an initial violence does not appear to play a role in increasing or decreasing the probability, timing, or development future misconduct for this particular group on inmates.

Conclusions

Upon validation, these findings call for continued research and perhaps a dialog regarding the utility of solitary confinement policies under certain contexts. This unique study sets the stage for further research to more fully understand how solitary impacts post-exposure behavior.
