Mighty Morphin’ age progression: how artist,age range,and morphing influences the similarity of forensic age progressions to target individuals

When children go missing, authorities sometimes release age progressed images that are intended to approximate the person's current appearance. The current studies measured the influence of the range between the time when the child went missing and the age portrayed in the age progression on the similarity between the progressions and current images of the targets. Experiment 1 examined whole face images and Experiment 2 examined internal features only. Eight artists were recruited to produce progressions at three age ranges. Also included were averaged (morphed) images made of progressions of the same individual at a given range by different artists. Progressions across shorter ranges produced images more similar than those across longer ranges, and target comparisons yielded higher similarity ratings than foil comparisons. Although there was much variability among artists, the morphed images performed better than the average rating given to all age progressions.     

Does ink age inside of a pen cartridge?

In questioned document examination and ink dating, it has been assumed that the ink inside of a pen cartridge does not begin aging until the ink is dispensed onto paper. Positive ion laser desorption (LD) mass spectra were obtained of ink-on-paper samples containing methyl violet, from new and old pens. Mass spectral studies with methyl violet have established the mechanism for how the dye degrades over time, and have provided structural information concerning the dye's degradation products. This information was used as an indication of the relative age of ink on paper. The LD mass spectrum of the ink from a new pen was indicative of "new" ink, whereas the spectra of the ink found in some older pens may appear to be either new or old. The ink from most of the old pens studied appears not to have aged, supporting the common assumption, whereas other ink samples produced "aged" ink spectra, suggesting otherwise.     

The “age of empire”: again?

Law and ways of thinking about law have historically been integral to processes of colonialisation and extension of empire. Contemporary forms of colonialism in a globalising legal environment may be less obvious, more nuances or even subconscious. However, the emergence of higher education as a trade commodity, the shift to fee-paying students as consumers and the market competition for international students among universities raise questions about the export and import of various forms of legal education, especially in the context of plural and mixed legal systems, debates about legal transplants, and concerns about legal imperialism. This article examines these issues and considers the place of comparative legal education in the contemporary environment facing university law schools.     

Minor or adult? Introducing decision analysis in forensic age estimation

Nowadays, forensic age estimation takes an important role in worldwide forensic and medico-legal institutes that are solicited by judicial or administrative authorities for providing an expert report on the age of individuals. The authorities’ ultimate issue of interest is often the probability that the person is younger or older than a given age threshold, which is usually the age of majority. Such information is fundamental for deciding whether a person being judged falls under the legal category of an adult. This is a decision that may have important consequences for the individual, depending on the legal framework in which the decision is made. The aim of this paper is to introduce a normative approach for assisting the authority in the decision-making process given knowledge from available findings reported by means of probabilities. The normative approach proposed here has been acknowledged in the forensic framework, and represents a promising structure for reasoning that can support the decision-making process in forensic age estimation. The paper introduces the fundamental elements of decision theory applied to the specific case of age estimation, and provides some examples to illustrate its practical application.     

How should we understand the effect of age on sexual recidivism?

Abstract

Research into the effect of age on sexual recidivism risk is a relatively new and developing area of interest and is likely to be of great interest for forensic practitioners responsible for the community supervision of sexual offenders. Meta-analytical and follow-up reconviction studies indicate an inverse relationship between age and sexual recidivism risk, where younger sex offenders pose a greater risk of reconviction than older sex offenders. This finding has led to the development of actuarial risk scales which identify younger sex offenders (<25 years) as posing the greatest risk. However, recent research studies have reported contradictory results to this assumption and found a non-linear relationship between age and sexual recidivism risk. Only a small number of studies have investigated the effect of age on sexual recidivism by comparing age bands and rates of sexual recidivism. Researchers have also considered the effect of age on actuarial risk, which risk factors are associated with which age bands and sexual recidivism rates between sex offender subgroups. The purpose of this paper is to integrate this research and to link commonalities between these studies. This paper organizes the effect of age on sexual recidivism into five categories: (i) the effect of age and actuarial risk; (ii) the effect of age on sexual arousal; (iii) the effect of age-at-release on sexual recidivism risk; (iv) the effect of age-at-first-offence on sexual recidivism risk; and (v) the effect of age on child molesters and rapists on sexual recidivism risk. Important differences were found between age bands of sexual offenders in terms of sexual recidivism risk and actuarial risk factors as well as differences between rapists and child molesters. The relative importance of factoring age when assessing risk in sex offenders is discussed.     

Victim age and capital sentencing outcomes in North Carolina (1977–2009)

Age is prominent among theories of criminology and victimology. It is less conspicuous in punishment theory, despite its emphasis in retributive theory and lawmaking. The present study evaluated competing ‘years of life lost’ and ‘vulnerable victim’ hypotheses to examine the influence of victim age in capital sentencing decisions. Using case file data on the population of capital murder trials in the State of North Carolina (1977–2009), our findings produce mixed results. Our quantitative analyses suggest that death sentences are significantly less likely in direct proportion to victim age. Killers of elderly victims are less likely to receive the death penalty; conversely, the odds of a death sentences are slightly greater for killers of child victims. Supplementary qualitative analyses suggest that while many child and elderly victims were not per se ‘vulnerable,’ a substantial subset of each clearly were treated as such. We discuss implications for vulnerable victim research and the role of quasi-legal factors in case outcomes.     

Comparison of the three age estimation methods: Which is more reliable for Turkish children?

BackgroundThree atlases—the GÖK, the Greulich–Pyle (GP), and the Tanner–Whitehouse (TW3)—are used frequently for age determination in Turkey. The purpose of this study was to evaluate the applicability of these three methods related to the skeletal age assessment for Turkish adolescents.Materials and methodsThe conventional roentgenograms of the left hands and wrists, elbows, shoulders, and pelvises of 333 healthy Caucasian children (164 females, 169 males) who fit the study and the criteria of each atlas were obtained. The mean differences (± standard deviation [S.D.] in years) between the chronologic age (CA) and the skeletal age (BA), which were obtained by using each age estimation method, were calculated and tested using t-test.ResultsFor girls, the most accurate method was the TW3 (mean differences (d): ?0.21 (p < 0.05)), following by the GP (d: 0.66 (p < 0.001), and the GÖK (d: 2.99 (p < 0.001)). For boys, the most accurate method was the GP (d: ?0.02 (p > 0.05)), followed by the TW3 (d: ?0.18 (p < 0.05)) and GÖK (d: 1.05 (p < 0.001)).Discussion and conclusionsResults show that the TW3 (for girls) and the GP (for boys) methods are more appropriate than the GÖK atlas for estimating the BA. GÖK could be used for boys aged 11–14 years but it should not be used for girls.     

Hypernatremia and subdural hematoma in the pediatric age group: is there a causal relationship?

Several researchers in the 1950's proposed that hypernatremia causes water to leave brain cells, shrinking the brain, thus tearing the bridging veins and resulting in subdural hematomas. Although the old literature suggests mechanisms linking the two in a cause and effect relationship, there is controversy as to whether hypernatremia leads to subdural bleeding or whether the reverse is true. This issue is important for forensic pathologists who must distinguish natural disease from trauma. An etiologic link between hypernatremia and subdural hematomas was suggested recently, and was proposed originally before Kempe's 1962 paper "The Battered Child Syndrome" which widely disseminated the concepts of child physical abuse, and of subdural bleeding resulting from non-accidental injury. Our study is a multifaceted investigation of infants which includes: a literature review, retrospective chart reviews of both living and deceased hypernatremic infants, a retrospective review of infants hospitalized with subdural hematoma, and a prospective collection of head injured, hypernatremic children. We conclude that hypernatremia, if present in association with subdural hemorrhage, is most likely secondary to intracranial pathology, and that hypernatremia often develops in critically ill infants suffering from a variety of medical conditions.     

Female serial killers in the early modern age? Recurrent infanticide in Finland 1750–1896

This article examines multiple infanticide in early modern Finland in which the same woman killed several newborns after repeated hidden pregnancies and childbirths. A well-documented case in Lohja, Nummi and Pusula Court of Assizes in 1874 is compared with nine other recurrent infanticides in Finland in the period 1750–1896. The context of the series of crimes and the reasons why it took so long to apprehend the murderers differed from the majority of reported infanticides, which were quite unplanned and the perpetrators of which were apprehended within days of the act. These offenders were serial killers who experienced a need to kill even if they were not literally serial killers according to modern conceptions of male-oriented serial killing. They did not deliberately get themselves pregnant with men in order to obtain psychological gratification from killing newborn babies. Rather, they resorted to killing several of their illegitimate babies as a solution of birth control because their first such crime went unreported or unprosecuted, probably as a result of the complicity of others. Such a perpetrator in the early modern age is labeled a ‘love-child murderess’ or a ‘burker of newborns’, depending on her relationship with the father or fathers of the victims. Serial killings of newborn babies as a solution of birth control continue to exist in modern times as serial neonaticide. It is suggested that a perpetrator of this category of crime in all ages be labeled a ‘birth controller’.     

The age at marriage of migrants during the industrial revolution in the region of liège

The articl7e examines the cities and towns in the Liège region during industrialization in the ninteenth century, focusing on the relationship between marriage, migration, and entry of people into urban areas. The average age at marriage was higher for in-migrants than for natives, but so was the intensity of nuptiality. Thus, the average age at marriage is not the sole statistic through which to approach questions about the socio-demographic consequences of arrival into town. Towns had several, seemingly closed, marriage markets, and it is important to pay attention to differential behaviors by taking this fact into account. Moreover, in-migration to an industrial city created opportunities to contract marriage, for women as well as men. Sometimes marriages occurred in the village, and were contracted to escape the old system and to prepare for the migration to the city of the young couple. Structural as well as life-course approaches must be combined for a thorough understanding of migration to industrializing cities.     

Incarcerated youths with high or low callous–unemotional traits: a comparison controlling for age of crime onset

The aim of this study was to analyze the relevance of callous–unemotional (CU) traits in incarcerated juvenile delinquents. A sample of 160 incarcerated male youths was used. Results showed that youths with high CU traits had an earlier age of crime onset and of trouble with the law, and also had higher levels of conduct disorder. When controlling for age of crime onset, youths with high CU traits showed higher levels of general psychopathic traits and of psychopathy taxon membership as well as lower levels of prosocial behavior, but no differences were found for self-reported delinquency, crime seriousness, impulsivity-conduct problems, and general conduct problems. Also, no significant associations of CU traits with self-reported delinquency and crime seriousness were found when controlling for age of crime onset. Future studies of CU traits should take into account the specific importance of age of onset.     

Validity of Demirjian and Willems methods for dental age estimation for Malaysian children aged 5–15 years old

BackgroundOne of the most commonly used method for dental age assessment is the method reported by Demirjian and coworkers in 1973. It was later modified by Willems and coworkers whereby they &ldquo;performed a weighted ANOVA&rdquo; in order to adapt the scoring system.AimTo evaluate the applicability of Demirjian and Willems methods for dental age estimation for Malaysian children and to correlate the accuracy of the findings with the chronology of tooth development of premolars and second molars.Materials and methodsA total of 991 dental panoramic radiographs of 5–15-year-old Malaysian children were included in the study. The mean Demirjian and Willems estimated ages were compared to the mean chronological age.ResultsThe mean chronological age of the sample was 10.1 ± 2.8 and 9.9 ± 3.0 years for males and females respectively. Using the Demirjian method, the mean estimated dental age was 10.8 ± 2.9 years for males and 10.5 ± 2.9 years for females. For Willems method, the mean estimated age was 10.3 ± 2.8 years males and 10.0 ± 3.0 years respectively.ConclusionsWillems method was more applicable for estimating dental age for Malaysian children. Overestimation in Demirjian method could be due to advanced development of second bicuspids and molars.     

The forensic pathology of nonagenarians and centenarians: do they die of old age? (The Auckland experience)

The aim of this study is to provide awareness of the common causes of death and their associated trends in the very aged. Forensic autopsies on patients aged >90 years were reviewed. The study lasted from January 1, 1988 to December 11, 1998 and was done in Auckland, New Zealand, the population of which is 1.3 million. Cases were divided into natural or unnatural deaths. Of the total of 319 cases, 272 (85%) deaths were natural. Of those, only 13 (5%) were "written off" as being attributed to old age or senile debility. The most common causes of death were ischemic heart disease (IHD), 74 cases (23%); bronchopneumonia, 37 cases (12%); fractures, 28 cases (9%); acute myocardial infarction, 25 cases (8%); cerebrovascular accident, 19 cases (6%); and ruptured aneurysm, 17 cases (5%); 61 (19%) deaths were multifactorial. Fractures, either as the primary cause of death or as a complicating factor, accounted for 29 cases, third only to IHD and bronchopneumonia. Forty-seven deaths (15%) were unnatural; of those, 43 were accidents, 3 were suicides, and 1 was a homicide. From these results it is clear that the very elderly succumb to disease; they do not often die of old age.
