Bone age assessment: the applicability of the Greulich-Pyle method in eastern Turkish children

The aim of this study was to investigate whether or not the Greulich-Pyle (GP) method is adequate for Turkish children. A group of 767 individuals (425 girls and 342 boys) between 7 and 17 years were studied. Bone age (BA) from plain radiographs of left hands and wrists by GP standards was estimated. The total mean differences between BA and chronological age (CA) for girls and boys were found to be 0.20 and -0.13 years, respectively. There were significant differences between BA and CA in age groups 7-, 8-, 10-, 11-, 12-, 13-, 15-, and 16-year-olds for girls and 7-, 10-, and 12-year-olds for boys. The results of this study suggest that the mean differences between BA and CA are low enough to be of no practical significance, and thus, for the time being unless any other methods will be proved more useful, this method could be used in all age groups.     

The third molar as an age marker in adolescents: new approach to age evaluation

Adolescence is a relatively short period between childhood and adulthood. It is very difficult to determine adulthood based on biological indicators. The third molar may be considered a potential age marker for the period between the ages of 16–21. Our study evaluated a set of 1700 panoramic radiographs of individuals aged between 5 and 21 years. Results confirmed the statistically significant difference in the course of third molars development. The mean deviation for individuals with one third molar agenesis is ?0.98 years, for individuals with two third molars agenesis ?1.89 years, and with three molars agenesis ?3.28 years. Thus, the extent of the deviation is directly proportional to the number of unformed third molars. The calculation of age according to the mean of stages of all third molars could lead to the underestimation of age. No intergender differences were found. Age determination using third molars could be used for forensic purposes.

Sexual Dimorphism in Finger Ridge Breadth Measurements: A Tool for Sex Estimation from Fingerprints

Previous research has demonstrated significant sexual dimorphism in friction ridge skin characteristics. This study uses a novel method for measuring sexual dimorphism in finger ridge breadths to evaluate its utility as a sex estimation method from an unknown fingerprint. Beginning and ending in a valley, the width of ten parallel ridges with no obstructions or minutia was measured in a sample of 250 males and females (N = 500). The results demonstrate statistically significant differences in ridge breadth between males and females (p < 0.001), with classification accuracy for each digit varying from 83.2% to 89.3%. Classification accuracy for the pooled finger samples was 83.9% for the right hand and 86.2% for the left hand, which is applicable for cases where the digit number cannot be determined. Weight, stature, and to a lesser degree body mass index also significantly correlate with ridge breadth and account for the degree of overlap between males and females.     

Examining the prevalence and correlates of a ‘senior citizen discount’ in US federal courts

Few studies focus on age as a factor influencing judicial decision-making, in spite of the widespread use of age as a control variable. Although the limited research to have done so is inconsistent, most scholars agree that age may be race- and/or gender-graded in a manner that produces more severe sentences for certain race–gender–age combinations, especially for young males who are Black or Latino. Less consensus exists with regard to whether older defendants are granted more leniency in the sentencing process and, if so, if the effects of older age are also race- and/or gender-graded. The present study examines this question by examining data from the United States Sentencing Commission. The data presented reveal three noteworthy findings. First, a ‘senior citizen discount’ exists insofar as judges afford more leniency in sentencing to older offenders than their younger counterparts. Second, compared to older males, older females were treated with greater leniency by judges. Finally, whereas Latinos 60 and over were treated with greater severity at the stage of incarceration compared to similarly situated Whites, Blacks received shorter sentence lengths on average. These results are analyzed within the framework of the focal concerns perspective.     

Pubic Symphyseal Age Estimation from Three‐Dimensional Reconstructions of Pelvic CT Scans of Live Individuals

Skeletal age estimation using the pubic symphysis is a reliable and popular practice among forensic anthropologists. In instances in which accessing the skeleton is impossible, such as in the case of living individuals, three‐dimensional (3D) reconstructions of computed tomography (CT) scans can be created and analyzed for aspects of the biological profile. This study examined 3D reconstructions of pelvic CT scans of a sample of 44 live adults to estimate age using the Suchey–Brooks J Hum Evol 1990;5(3):227‐38 method. Images were created using OsiriX software (Pixmeo, Geneva, Switzerland). Estimated age ranges based on the 3D‐CT images captured the true age of the individual at the time of the CT scan 79.5% of the time with good intra‐observer reliability. The features best visualized on the 3D images included the ossific nodule and the pubic symphyseal rim. This study shows that clinical CT scanning parameters are adequate for creating 3D images to be analyzed for age using the pubic symphysis.     

Using PMCT of Individuals of Known Age to Test the Suchey–Brooks Method of Aging in Victoria,Australia

The estimation of an individual's age at death plays a critical role in the investigation of unidentified human remains. The Suchey–Brooks method, which involves the analysis of degenerative morphological changes in the pubic symphysis, is currently widely used to estimate age in adults. This study tested the applicability of the Suchey–Brooks method on a contemporary adult Australian (Victorian) subpopulation by observing three‐dimensional volume‐rendered postmortem computed tomographic (PMCT) reconstructions of the pubic symphysis of 204 individuals aged 15–100 years. Results showed the method was reliable for females (85% correct allocations) but not for males (67% correct allocations). It is therefore recommended that extreme caution be used when applying the Suchey–Brooks method for estimating age at death of an individual in this subpopulation from PMCT images. The results suggest further investigation into alternate age estimation methods is required.     

对下调法定最低刑责年龄的省思

此次刑法修正案(十一)对最低刑事责任年龄进行下调,可以在很大程度上避免一部分已满12周岁未满14周岁的未成年人倚仗法律保护肆意实施危害行为的"钻法律之空子"的情况发生,能够有效提升法律的威慑力,使公众免受"12岁恶魔"的伤害。在作为调整对象的低龄未成年人一侧,最低刑责年龄的下调意味着他们必须为自己的不法行为承担责任、付出代价。戴上这只法律"金箍"的未成年人将不得不在法律的框架内保持自身行为的检点合法。当然,虽然法律对最低刑事责任年龄进行了下调,但犯罪未成年人仍然需要在"教育为主、惩罚为辅"的矫治环境中得到救赎,既不能"一放了之",也不能"一关了之"[1]。在"疏"与"堵"并行的同时加强相关法律制度的衔接,使低龄未成年人可以在一个相对完善的制度设计中树立起对法律以及他人权益的敬畏之心。
