A new experimental approach to computer-aided face/skull identification in forensic anthropology

The present study introduces a new approach to computer-assisted face/skull matching used for personal identification purposes in forensic anthropology.In this experiment, the authors formulated an algorithm able to identify the face of a person suspected to have disappeared, by comparing the respective person's facial image with the skull radiograph. A total of 14 subjects were selected for the study, from which a facial photograph and skull radiograph were taken and ultimately compiled into a database, saved to the hard drive of a computer. The photographs of the faces and corresponding skull radiographs were then drafted using common photographic software, taking caution not to alter the informational content of the images. Once computer generated, the facial images and menu were displayed on a color monitor. In the first phase, a few anatomic points of each photograph were selected and marked with a cross to facilitate and more accurately match the face with its corresponding skull. In the second phase, the above mentioned cross grid was superimposed on the radiographic image of the skull and brought to scale. In the third phase, the crosses were transferred to the cranial points of the radiograph. In the fourth phase, the algorithm calculated the distance of each transferred cross and the corresponding average. The smaller the mean value, the greater the index of similarity between the face and skull.A total of 196 cross-comparisons were conducted, with positive identification resulting in each case. Hence, the algorithm matched a facial photograph to the correct skull in 100% of the cases.     

Max Frei theory revisitation: does really strokes depth change along time?

A serious problem in questioned document examination is to establish the age of written lines. With respect to paper dating, in the past, Max Frei theory (based only on microscope analysis) claimed that strokes are time-dependent. Therefore, according to this theory, it has been asserted that from the analysis of the strokes depth changes it is possible to try to date the handwritten document (to find out that the document is older than ...). In the present work, we investigate the strokes depth change by a laser profilometer considering not only the time but also microclimatic variations. First, we analyze the stability of stroke characteristics along the time. In particular, we demonstrate that if the document is preserved without change of temperature and humidity, the depth of the strokes has not appreciable changes. In this way, we have the purpose to verify the real possibility of documents dating by means of Max Frei theory. Subsequently, we test how the 3D profile of strokes changes in connection with the microclimatic variations. In particular, we test humidity variations. With this experiment, we show that humidity variations reduce the strokes depth. Moreover, this effect shows a non-linear trend, leaving a hysteresis on the depth. Finally, we show that the analysis of 3D stroke profile is unable to determine the age of documents.     

"Volunteering by chance" to promote civic responsibility and civic engagement: does it work?

This study investigated the effectiveness of a program to promote civic responsibility and prevent antisocial behavior in a sample of Italian adolescents. Participants were 83 Italian male adolescents, attending the second year of high school (Mean age = 15.79; SD = 0.87). In order to test the efficacy of different strategies (in-classroom training and service activity in a voluntary organization) we divided students into two experimental groups--one classroom of students participated in both strategies (training + volunteering group) and another classroom only participated in the training (training only group)--and one control group. Process and efficacy evaluations were completed. Data were collected before and following the intervention. The process evaluation revealed that the program was highly accepted and appreciated by students. The efficacy evaluation revealed no intervention effects on civic responsibility. However, the training + volunteering group reported a significant decrease in antisocial behavior after the program. Thus, the program was effective in preventing antisocial behavior but not in promoting civic responsibility in our sample.     

Hair and urine testing to assess drugs of abuse consumption in couples undergoing assisted reproductive technology (ART)

For the first time in Europe hair and urine testing have been applied to assess drugs of abuse consumption in couples undergoing assisted reproductive technology and the eventual association of toxic habits with other lifestyle, health status and sociodemographic factors was also investigated. Couples attending five assisted reproduction centers in Rome were invited to join the study. When they presented at the Centre for the visit, they were asked to answer a structured questionnaire concerning sociodemographic characteristics and lifestyle habits, and at the same time to provide hair and urine samples. Hair and urine testing for drugs of abuse, urinary profile of principal endogenous steroids involved in fertility process (testosterone, epitestosterone, androsterone, etiocholanolone and dehydroepiandrosterone) and of alcohol and tobacco smoke biomarkers were performed with validated methodologies. Of the 594 enrolled individuals (297 couples), 352 (164 couples and 24 single individuals from the couple) completed the questionnaire and gave both hair and urine samples, apart from 3 bald men, who only gave urine samples. Urine testing showed an overall 4.8% (17 individuals) positivity to drugs of abuse: 4.2% to cannabinoids, 1.4% to cocaine and 0.85% to both drugs. Results of 4cm segment hair samples testing matched those from urine samples. Thus, taking together, results of urine and hair testing confirmed repeated use of cannabis, cocaine and both drugs in 3.7, 0.85 and 0.57% examined individuals, respectively. Drug consumers were in a statistically higher percentage active smokers and alcohol drinkers, less prone to physical activity and with a trend towards higher weight than non consumers. Finally, repeated drug consumption was associated with significant lower concentration of urinary testosterone in males and of urinary dehydroepiandrosterone in females. The findings of the present study confirm the suitability of urine testing to disclose recent drugs of abuse consumption and of hair analysis to verify repeated consumption. Association between different toxic habits and sedentary lifestyle is also substantiated by the obtained results in our cohort of couples attending assisted reproduction centers.     

Age estimation in children by measurement of open apices in tooth roots: Study of a Mexican sample

The aim of this cross-sectional study was to test the accuracy of Cameriere's European formula for age assessment in a large sample of Mexican children. The accuracy of dental age estimation was defined as how closely real age, measured as the difference between chronological age (CA) and dental age (DA), could be predicted. Digitalized orthopantomographs of 502 Mexican children (254 girls and 248 boys), aged between 5 and 15 years, were analyzed. The seven left permanent mandibular teeth were evaluated using Cameriere's method. Intra- and inter-observer variability for this technique was tested on a small random sample. Dental age was estimated for each individual and compared with known chronological age. Accuracy was measured as the difference between known chronological age and dental age and tested for significance with the mean prediction error (ME). The standard deviation and 95% confidence interval of the mean difference were also calculated. ME was 0.63 years for girls and 0.52 years for boys. ME was found to be slightly overestimated by 0.10 years for girls, but was correctly estimated for boys with an accuracy of 0.00. In conclusion, this method is very useful and may be recommended for practical application both in clinical dentistry and forensic procedures on the Mexican population.     

The Relationship Between Childhood Physical Abuse and Adult Attachment Styles

The purpose of the study was to identify the insecure adult attachment style associated with childhood physical abuse. Five hundred fifty-two female and 294 male university students completed questionnaires on their child abuse history, adult attachment style, and other variables. Regression analyses were completed. A history of physical abuse was associated with attachment avoidance while controlling for other forms of childhood abuse. Some support was also found for an association between physical abuse and attachment anxiety. Social support, as a control variable, was found to be an important predictor of attachment avoidance and attachment anxiety. A history of childhood physical abuse has important and specific impacts on intimate adult relationships with social support acting as a possible protective factor.     

Participation and commitment in third-party research funding: evidence from Italian Universities

Over the last few years, the emergence of universities’ third mission has significantly affected objectives, sources of funding and financing methods, as well as the management, of universities. Although the university–industry relationships have been widely investigated, several interesting theoretical and empirical issues still remain open in the literature. In this paper we construct an original data set, combining financial information with structural and organizational data on Italian University departments, with a twofold aim. First, to describe the importance and the extent of third-party funding in the Italian system of research as well as the pattern of evolution over the last few years. Second, to investigate the factors that influence both the probability and the intensity of the commitment of departments in third-party activities by building a multi-level framework combining factors at individual, departmental, university and territorial levels. The results obtained suggest a number of policy implications for universities and policy makers. On one hand, universities should explicitly recognize the role of dedicated internal organizations and provide training for professional staff capable of acting as value-added intermediaries. On the other hand, if policy makers wish to improve the relationships between universities and external actors, disciplinary differences across departments as well as regional inequalities in growth levels should be carefully considered, giving up a one-size-fits-all approach.     

In need of a cultural shift to promote restorative justice in Southern Europe

The article describes the main results of a European project on restorative justice (RJ) called Freedom Wings (FW) and presents a new model to promote RJ in Southern Europe, which was developed from FW findings. The principal mission of the FW project is to disseminate best practices of RJ within a transnational network and to promote community participation in conflict prevention and resolution, in order to support individual and social well-being. This paper presents the main findings of multiagency and professional focus groups exploring restorative approaches and community justice. Observation of experts’ social representation of RJ helped the authors to understand the operation of the justice systems in each country and the attitudes of senior officials towards implementing restorative practices in a way that actively involves the community. The analysis shows the necessity of a cultural change in order to switch from a form of RJ managed by the judicial system to one led by the community. The EU project enabled the research team to theorize a model for promoting a relational and restorative community.
