HealthConnect and the duty of care: a dilemma for medical practitioners

This article asks whether medical practitioners' duty of care to their patients will encompass participation in the HealthConnect shared electronic records initiative. Medico-legal aspects of the HeathConnect scheme relating to the nature of shared electronic health record summaries (SEHRS) are examined, focusing on their function as an element of patient care and their ultimate purpose. The analysis is based on the premise that an incomplete and hence inaccurate shared electronic health record summary is clinically and legally more perilous than no record at all.     

Multivariate analysis for estimating the age of a bloodstain

Our objective is to provide crime laboratories with a technique for estimating the age of a bloodstain. Toward that goal, we have used multiplexed, real-time RT-PCR (or qPCR) to determine the relative stability of different-sized segments of the same RNA species as well as differences in stability between two different RNAs' change over time in bloodstains. Our results indicate that a multivariate analysis of the changing ratio of the different RNA segments can be used to differentiate between samples of different ages in the defined population. Bloodstains from 29 of 30 donors could be partitioned into different ages using this technique. Although further improvements will be required before this approach can be implemented in crime laboratories, the multivariate analysis holds promise of providing a reliable approach for temporally linking a bloodstain to the commission of a crime or excluding a bloodstain as being irrelevant to the case in question.     

Equations for estimating age at death from the pubic symphysis: a modification of the McKern-Stewart method

Morphological changes of the pubic symphysis provide an important means of estimating age at death in the adult skeleton. Today, the most widely used method of symphysial aging is the three-component system devised by McKern and Stewart for males and modified by Gilbert and McKern for females. Examination of the published data for both sexes reveals that the relationship of total symphysial score with predicted age and observed standard deviations can be expressed by a set of simple linear and polynomial equations. This approach is more statistically efficient since it uses the total data base rather then independently treated data subsets in predicting age from total symphysial score. It has the added advantage of providing a simple method of predicting symphysial age on small computers or programmable calculators.     

Multiple-probe thermography for estimating the postmortem interval: II. Practical versions of the Triple-Exponential Formulae (TEF) for estimating the time of death in the field

A simple, reliable, and relatively accurate method for estimating the time since death is described. It is based on the Triple-Exponential Formulae (TEF), which are devised for the first time in this study. The postmortem cooling rate of the brain, liver, and rectum in 117 forensic cases were investigated (Part I). The method can be used in the field as a computer program, reference graph, or reference chart-ruler. The program is simple and can easily be run by any user. There are six reference graphs representing the average brain, liver, and rectal cooling curves for naked and covered body groups. The ruler is designed for the rectal cooling curves for covered and naked bodies. This method requires one temperature measurement of the chosen body site and the environment. The postmortem interval is estimated as a probable value +/- a possible range of time estimates with a built-in confidence limit.     

Validities and abilities in criminal profiling: the dilemma for David Canter's Investigative Psychology

This article discusses misconceptions in Bennell, Jones, Taylor, and Snook's (2006) critique of Kocsis (2003a) concerning the validities and abilities surrounding criminal profiling. It also, in part, serves to canvass the approach of investigative psychology and what may be viewed as an imperative for some of its proponents to challenge evidence into the validity of criminal profiling, which is not easily reconcilable with that ideology.     

Patent ductus arteriosus as a natural cause of pulmonary hemorrhage in infants: a medicolegal dilemma

Patent ductus arteriosus (PDA) is a recognized risk factor for massive pulmonary hemorrhage (MPH) in the newborn and is generally seen in association with other MPH risk factors such as prematurity. We report 6 cases of sudden and unexpected death of infants older than 4 days with MPH and PDA at autopsy. The cases were reviewed for other factors that could contribute to MPH to ascertain whether PDA is directly linked to MPH. Histology samples were examined for distribution of hemorrhage in the lungs and iron stained for hemosiderin evaluation. All of the cases had clinical histories and scene examinations which raised the differential diagnosis of mechanical asphyxia in the form of so-called overlayings. The diagnostic dilemma of attributing the MPH to the PDA as the sole cause, dual cause, or incidental finding is discussed. These cases illustrate the medicolegal dilemma faced by the pathologist, as well as the need for further research into the potential association of PDA with MPH.     

A framework for estimating probability of a match in forensic bite mark identification

In forensic dentistry, a human expert typically does the comparison and identification based on bite marks. Unlike DNA analysis, however, there is no quantitative basis with which to assign a probability for this given match. This paper proposes a framework for empirically estimating the probability of such a bite mark match and reports on initial experimental results. The methodology involved collection of dental population data (3D dental casts and bite mark images), image analysis for quantitatively measuring the degree of match (based on chamfer distance), and performing a logistic regression analysis using the collected population data to estimate the probability of match from the calculated degree of match. The model correctly predicted 35 of the 42 matches and 585 of the 588 mismatches. The method also has potential for use in other forensic applications in which the assignment of quantitative probabilities is important.     

Conduct unbecoming: The dilemma of a school's responsibility in respect of teacher misconduct towards pupils

It was recently remarked that if the infamous schoolmaster, Wackford Squeers, in Charles Dickens's Nicholas Nickleby , was around today his pupils would probably accuse him of assault and the police would be paying a visit to his school, Dotheboys Hall. Though a casual comment, a great deal of truth lies therein. In the 'rights culture' of today, the manner in which adults may exercise authority over children is markedly different to that of even 20 years ago. The majority of teachers act in a professional manner and carry out their duties, often under great pressure, with the best interests of their students uppermost in their minds. However, this is not always the case. With reasonable frequency, there are reports of teachers behaving towards their students in ways which range from inappropriate to culpable. In the worst scenario the accusations are of sexual abuse, but there are also those of physical or verbal bullying. There is nowadays an increased recognition of the harmful and lasting effects of different forms of abuse, and the responsibility of those in authority to prevent it happening. In recent years New Zealand school administrators have been faced with dealing appropriately with allegations of a teacher's misconduct in a variety of different ways towards their students. A school board of trustees has a dilemma in that it must discharge dual responsibilities, in respect of its students and its staff. This article examines the legal implications of those responsibilities. It also considers the responsibility of a school in a wider context — to other schools and to the community at large.     

Mainstream medicine versus complementary and alternative medicine in the witness box: resolving the clash of ideologies

Mainstream medical philosophy and practice differ in many respects from those of complementary and alternative medicine (CAM), differences which are explored in this article. Because of a resurgence of CAM therapies, courts and tribunals will scrutinise CAM in more and more contexts in the future. Such court cases may require the resolution of conflicts between opinions of CAM and medical experts. This article considers how courts evaluate such opinions where experts hold conflicting ideologies or philosophical approaches, and addresses the following questions: Do the opinions of CAM practitioners qualify as "expert" opinions in court? How do the courts examine the basis of such opinions? Are they systematically given less weight than the opinions of mainstream medical practitioners? Will recent procedural reforms for hearing expert evidence make it easier for courts to resolve these issues?

A model for estimating the number of glass fragments transferred when breaking a pane: experiments with firearms and hammer.

Numerous publications have shown the importance of transfer in the interpretation of glass evidence. As this phenomenon is also highly variable, it was decided to test the hypothesis that there exists a means to predict the number of fragments recovered at time t = 0. Panes of float glass-of different types and thickness-were broken using either a firearm or a hammer. It was decided to choose a firearm as the main breaking device, as it allowed not only to have more reproducible conditions but also to acquire knowledge in a field where little has been published. Despite the inherent variation in the breaking process, the results show that using a statistical model it is possible to predict the number of fragments transferred onto a garment from the number of fragments transferred to the ground. This research also indicates the size and number of particles transferred onto a person, when breaking window panes of different types (float, laminated or toughened) with different breaking procedures.
