Recognition by forensic facial approximation: case specific examples and empirical tests

The skeletal remains of one individual found near Adelaide in 1994, although not known at the time, were the first evidence of what was to be a serial killing reported to have resulted in the highest casualty list to date in Australia (12 victims). Since the usual methods of identification could not be used or were unsuccessful on these remains, facial approximations were produced and advertised over the 4-year period following their discovery, in an attempt to help to identify them. However, no identification was made. In 1999, the remains were reported to be identified by radiographic comparison. Approximately 3 months before this identification was made, another facial approximation was produced by the first author (CNS), but this face was never advertised in the media. Although rarely reported in the literature, this paper provides an example where facial approximation methods were not successful in a forensic scenario. The paper also reports on empirical tests of the facial approximation created by the first author to determine if this facial approximation might have been useful had it been advertised. The results provide further evidence that high resemblance of a facial approximation to the target individual does not indicate recognizability, as the facial approximation was poorly recognized even though it bore good resemblance to the target individual. The usefulness of facial approximation techniques is discussed within the context of this case and more broadly. Methods used to assess the accuracy of facial approximations are also discussed and further evaluated.     

Assessing facial approximation accuracy: how do resemblance ratings of disparate faces compare to recognition tests?

In the past, the accuracy of facial approximations has been assessed by resemblance ratings (i.e., the comparison of a facial approximation directly to a target individual) and recognition tests (e.g., the comparison of a facial approximation to a photo array of faces including foils and a target individual). Recently, several research studies have indicated that recognition tests hold major strengths in contrast to resemblance ratings. However, resemblance ratings remain popularly employed and/or are given weighting when judging facial approximations, thus indicating that no consensus has been reached. This study aims to further investigate the matter by comparing the results of resemblance ratings and recognition tests for two facial approximations which clearly differed in their morphological appearance. One facial approximation was constructed by an experienced practitioner privy to the appearance of the target individual (practitioner had direct access to an antemortem frontal photograph during face construction), while the other facial approximation was constructed by a novice under blind conditions. Both facial approximations, whilst clearly morphologically different, were given similar resemblance scores even though recognition test results produced vastly different results. One facial approximation was correctly recognized almost without exception while the other was not correctly recognized above chance rates. These results suggest that resemblance ratings are insensitive measures of the accuracy of facial approximations and lend further weight to the use of recognition tests in facial approximation assessment.     

Compensation for medical injury in New Zealand: does "'no-fault" increase the level of claims making and reduce social and clinical selectivity?

The issues of patient safety and quality of care have gained policy attention with a growing appreciation of the scale and impact of medical injury in health systems. While the focus is clearly on the prevention of iatrogenic injury, the question of patient compensation is now also considered important, if only because in fault-based tort systems the fear of litigation may itself be a barrier to the disclosure and open discussion of medical error. No-fault systems, by contrast, do not require proof of culpability, and thus may both reduce barriers to compensation and increase disclosure of error. Little evidence, however, is available on the performance of such systems. This article reports on the analysis of two data sources-a sample of hospital admissions and a complete set of compensation claims for medical injury. Both are for the same year and region of New Zealand, a country that has maintained a no-fault system of accident compensation for a quarter of a century. Just over 2 percent of hospital admissions were associated with an adverse event that was potentially compensable under scheme criteria. While the claims process was well targeted, the level of claims making and receipt was low, with the ratio of successful claims to potentially compensable events being approximately 1:30. Comparison of social and clinical characteristics of the two data sets revealed a degree of selectivity. Compared with the hospital events, the typical successful claimant was younger and female and was much more likely to have experienced a surgical adverse event that, while unexpected, was not due to substandard care. It is concluded that, in interpreting these results, account needs to be taken of a number of features unique to the New Zealand system. These include: the limited payoff for a compensation claim (no pain and suffering or lump sum, free hospital care); the relative complexity of the grounds for claim (either rarity and severity or practitioner error); and a history of limited litigation for medical error. This suggests that, while the New Zealand system is well targeted, cheap, and free of financial and legal barriers, a change in legal doctrine alone has not in itself been sufficient to remove completely the selective and low level of claims making traditionally associated with patient compensation under tort.     

Nordic Social Science Research and the American Nightmare

The purpose of the article is to review four major social science research projects currently under way in the Nordic countries, and to discuss the preconditions for, and the significance of, the manner in which the projects are organised. Four models for organising social science research are outlined, and applied to the projects. The main conclusion of the study, albeit of a tentative nature, is that whether a research project is organised according to one or other model is dependent upon the infrastructure of social science research, and the organisation of the wider society in the country concerned.     

Planned complex suicide by self-poisoning and a manipulated blank revolver: remarkable findings due to multiple gunshot wounds and self-made wooden projectiles

A remarkable case of complex suicide with poisoning and multiple self-inflicted gunshot wounds to the head is reported. After ingestion of a liquid insecticide, the victim shot himself twice in the head, once in each temple. Self-manufactured wooden dowels were used as projectiles in combination with conventional blank cartridges. The dowels had been glued on top of the blank cartridges and expelled by propellant gases. Moreover, the blank revolver used had been extensively manipulated in a rarely observed manner. Several occlusive devices had been removed from the barrel and the cylinder chamber to enable the expulsion of the wooden projectiles. The investigation of the methods used and the circumstances found at the scene pointed towards a planned complex suicide. A remarkable case with unusual projectiles, i.e., wooden dowels, fired by an extensively manipulated blank gun is reported, emphasizing the importance of close collaboration between the police firearm laboratory and forensic pathology in practical casework.     

Anthropological facial ‘reconstruction’ – recognizing the fallacies, ‘unembracing’ the errors, and realizing method limits

Despite being practiced for over the last 200 years, facial approximation methods remain in their infancy as the soft tissue prediction methods employed have not been tested and justified. Scientific testing is the only way forward and much of it is needed. The lack of systematic scientific tests in the past has enabled many misleading notions to become established. Many of these notions appear to have arisen and been sustained as a result of practitioner biases--this is clearly evident even in the name commonly used to describe the method of building faces from skulls, for "facial reconstruction" implies everything the method is not, e.g., technical/scientific, exact, and credible. Although facial approximation methods are useful for forensic investigation (even if they do not generate identifications through true positive recognitions of the faces), the public should beware of the marketing and political ploys employed within the profession. These ploys give rise to some impressive, but unjustifiable claims--but do not just take my word for it; evaluate the evidence for yourself with disregard to the indoctrination waged by the facial "reconstruction" field in general, including that promoted by what I have had to say here. Use your own reason and intellect and see which conclusions you reach.     

Can Local Ordinances Prevent Neighborhood Destabilization?

This article assesses the ability of local housing ordinances to prevent neighborhood destabilization, specifically that arising as a consequence of the most recent housing crisis. We evaluate the degree to which vacancy registrations and point-of-sale inspection requirements influenced housing market outcomes during the housing crisis. With comprehensive real property data from Cuyahoga County, Ohio, we measure outcomes that characterize housing market distress including foreclosures, sales below the tax-assessed value, bulk sales, flipping, and property tax delinquency. We evaluate outcomes across properties in regulated and unregulated municipalities using matching procedures on linked data containing property, neighborhood, loan, and transaction characteristics. We find evidence that vacancy registrations substantially reduce foreclosures. In contrast, we find little evidence that point-of-sale inspections reduce undesirable transactions. Rather, properties in cities with inspection requirements displayed higher levels of foreclosure and tax delinquency relative to the control group during the study period.     

Facial Soft Tissue Depth Measurement: Validation of the 75‐Shormax

The shorth and 75‐shormax were recently posited as an improved alternative to the arithmetic mean for describing facial soft tissue thicknesses in craniofacial identification. The shorth better estimates the data peak, while the 75‐shormax provides improved provisions for a long right tail. When first proposed, the 75‐shormax was subjectively gauged. Herein, shormax errors are calculated at every whole percentile to quantitatively determine zones of error minimization in two large samples: (a) CT data of French adults, n‐range = 211–469 individuals; and (b) all C‐Table data, n‐range = 60–1065 individuals [including part but not all of sample (a)]. The smallest residuals were found at the 79th percentile (mean of raw residuals) and the 74th percentile (mean of absolute residuals). The 75‐shormax is subsequently verified as good error minimizer since the absolute differences carry the greatest weight and the 74th percentile closely approximates the 75th percentile.     

The economics of AIDS-related health insurance regulations: Interest group influence and ideology

The projected growth in the U.S. in the number of persons with AIDS has created concern about sources of financing the costs of health care services for persons with AIDS. Private health insurers have modified or considered modifying underwriting practices in response to the AIDS epidemic, but several state governments have developed significant regulatory constraints on AIDS-related underwriting practices. We model the state government's decision to impose AIDS-related regulatory constraints (HIV testing restrictions, restrictions on the use of information about sexual orientation, and mandated AIDS coverage). We find that HIV-testing restrictions tend to be more likely in states with relatively high AIDS prevalence rates and insurance industries that are relatively weak politically. States with prevailing attitudes favorable to persons with AIDS (i.e., relatively liberal states) are more likely than other states to impose HIV-testing restrictions. Measures of prevailing attitudes (ideology) appear to be the primary determinants of regulations prohibiting questions about sexual orientation, but economic interests are the primary determinants of mandated AIDS coverage.The authors would like to acknowledge the helpful comments and suggestions of Ned Becker, Janet Bronstein, David Colby, Patrick Donnelly, Roger Faith, Robert Hughes, Robert McGuire, Delfi Mondragón, Mike Morrisey, Jack Nelson and an anonymous reviewer, with the usual disclaimer.
