Accuracy of Three Age Estimation Methods in Children by Measurements of Developing Teeth and Carpals and Epiphyses of the Ulna and Radius

Abstract: The aim of this study was to compare the accuracy of three methods for age estimation in children: the measurements of open apices in tooth roots (T), the ratio between the total area of carpal bones and epiphyses of the ulna and radius (HW), and the combined method (THW). The sample consisted of 288 Caucasian Italian children (152 boys and 136 girls) aged between 5 and 15 years. Accuracy was determined as the difference between estimated age and chronological age, and accuracy was assessed by analyzing individuals’ orthopantomograms and hand‐wrist radiographs. Accuracies were 0.41 years for girls and 0.54 years for boys with the THW method; for the HW method, 1.00 years for girls and 0.92 years for boys; and for the T method, 0.62 years for girls and 0.71 years for boys. THW is the most accurate technique for age estimation in these children.     

Metacarpal sexual determination in a Spanish population

Anthropologists and forensic pathologist determine the sex of skeletons by analyzing quantitative and qualitative characters in the bone remains. Generally, the skull and os coxae are the elements most used, but they are not always preserved. In such cases, the investigator needs to have available other techniques based on different remains. The aim of the present work is to develop and describe discriminating functions for sex determination in a recent Spanish population using metacarpal morphology. A sample of bones corresponding to a contemporary Spanish population deposited at the Complutense University of Madrid (UCM) was analyzed. This sample comprised 697 metacarpals, corresponding to 79 adult individuals (37 men and 42 women). These allowed us to obtain 120 unifactorial discriminant functions. We selected the 10 equations, one for each metacarpal from both hands, that provided the best sexual discrimination. The correct sex classification rank progressed from 81%, for right (R) metacarpals IV and V, to 91%, for left (L) metacarpal II. The results suggest that metacarpals are structures that can be used for sex determination in paleoanthropological and forensic identifications.

The Possibilities and Limitations of Forensic Hand Comparison

On recordings of certain crimes, the face is not always shown. In such cases, hands can offer a solution, if they are completely visible. An important aspect of this study was to develop a method for hand comparison. The research method was based on the morphology, anthropometry, and biometry of hands. A new aspect of this study was that a manual and automated test were applied, which, respectively, assess many features and provide identification rates quickly. An important observation was that good quality images can provide sufficient hand details. The most distinctive features were the length/width ratio, the palm line pattern and the quantity of highly distinctive features present, and how they are distributed. The results indicate that experience did not improve the identification rates, while the manual test did. Intra‐observer variability did not influence the results, whereas hands of relatives were frequently misjudged. Both tests provided high identification rates.     

Correspondence

This article surveys the problems facing the existence of intellectuals in the twenty-first century by reflecting on the historical and conceptual conditions that have enabled them to flourish in the past but less so in recent times. The first part considers several strands of contemporary philosophical and social thought that, despite their progressive veneer, have served to undermine the legitimacy of the intellectual's role. This delegitimation is largely traceable to a scepticism about the existence of ideas that are simultaneously normative and manipulable. The second part deals with the rise of anti-intellectualism in philosophy and psychology in the twentieth century, focusing especially on the debates surrounding ‘psychologism’. The third part examines what remains the most attractive expression of anti-intellectualism, namely, invisible-hand thinking and its late nineteenth-century transformation through the influence of statistics, evolution and epidemiology. In the conclusion, the main strands of the argument are drawn together in a sketch of an overall account of the rise and fall of the intellectual in the modern era. Finally, I provide one strategy for stemming the current tide of anti-intellectualism by reinterpreting the currently popular concept of ‘heuristics’.     

根据创口射击残留物推断“5.4”式手枪射击距离的研究

目的利用环境控制扫描电镜/能谱仪（SEM/EDX）研究枪弹创射入口周围射击残留物与射击距离的关系,探讨其能否用于射击距离的判断。方法采用＂＂5.4＂＂式手枪分别在5、10、15、20、30、40、50、60、70、80、90、120cm处射击乳猪皮肤,利用SEM/EDX观察创口周围GSR的分布和成分,并建立回归方程。结果射击距离和GSR颗粒数量之间总体表现为直线关系,并建立了相应的回归方程。当射击距离为10~90cm时,用该方程推断射击距离效果较好。结论检测创口周围GSR可望用于判断“5.4”式手枪的射击距离。     

Uses Of Blood: Re-Reading Matt. 27:25

‘The entire people cry out, “His blood be on us and on our children.”’ Is this the epochal ‘no’ of Israel renouncing its birthright? The legal precedent is not in delict but in contract, in treaties and covenants in which an entire people bind themselves and their descendants, their entire nation, in perpetuity by an imprecatory curse-oath identifying themselves and their descendants with a blood sacrifice that seals the contract. Legally, treaties and covenants require contemporaneous ratification. The author of Matthew’s gospel obtains the acclamations of the other actors, Pilate, the soldiers, the chief priests, scribes and elders and from the sign atop the cross by the formulaic talisman, ‘King of the Jews’ or ‘Israel’s King’ that each recite. He obtains the crowd’s acclamation from Pilate using together the words ‘Christ’ (Messiah) and ‘blood’ and employing a Jewish hand washing ritual. The purpose of the hand washing ritual was to forgive Israel for the guilt of innocent blood. However, Pilate uses this ritual meant to forgive Israel for its extreme opposite perverse purpose to condemn Israel. But the crowd uses the words ‘blood on’ in a different sense that evades Pilate’s request. ‘Blood on’ in the sacrificial system meant acceptance of a sacrificial blood offering.

Estimation of stature from hand impression: a nonconventional approach

Stature is used for constructing a biological profile that assists with the identification of an individual. So far, little attention has been paid to the fact that stature can be estimated from hand impressions left at scene of crime. The present study based on practical observations adopted a new methodology of measuring hand length from the depressed area between hypothenar and thenar region on the proximal surface of the palm. Stature and bilateral hand impressions were obtained from 503 men of central India. Seventeen dimensions of hand were measured on the impression. Linear regression equations derived showed hand length followed by palm length are best estimates of stature. Testing the practical utility of the suggested method on latent prints of 137 subjects, a statistically insignificant result was obtained when known and estimated stature derived from latent prints was compared. The suggested approach points to a strong possibility of its usage in crime scene investigation, albeit the fact that validation studies in real-life scenarios are performed.
