Unaccompanied Migrant Adolescents in the Italian Context: Tailored Educational Interventions and Acculturation Stress

The migration experience is normally associated with acculturative stress; this condition assumes relevance when the migrant is a minor alone. The aim of this study was to explore perceptions about the migration process and educational interventions offered by host-community social workers. We conducted semi-structured interviews with 10 unaccompanied migrant adolescents that had finished their educational pathways in the traditional community centers. Interview results were analyzed using NVivo 9, based on the grounded theory. The main results of the study are related to the incompatibility between the educational intervention of host communities and minors’ projects and motivations.     

Political activism in Iran: strategies for survival,possibilities for resistance and authoritarianism

This article examines mobilizations and activism in authoritarian settings by considering the case of Iran. By focusing on the transformation of activism since the 1990s and the green movement, it advances an explanation of how oppositional political groups have been able to survive and produce forms of resistant subjectivity despite authoritarian constraints. In order to do so, the article brings together two scholarly traditions, namely Social Movement Theory (SMT) and the study of subjectivity and resistance as framed by Sari Hanafi. SMT explains how activists have been able to navigate repression and create opportunities for mobilization while shifting between formal and informal politics. The study of subjectivity helps conceptualize the type of subjects or political citizens that authoritarian environments generate. The article builds on field research with activists conducted in Iran and Turkey between 2007 and 2016. It argues that authoritarian constraints allow autonomous activism to flourish while emptying of meaning the regime-sanctioned political infrastructures.     

Mobile Borders in Urban Daily Mobility Practices in Santiago de Chile

In cities today, the possibility of being confined is not only applicable to fixed areas, like work or home, but it may also occur while moving. This is because high levels of mobility, long distances, and extended hours of daily travel, along with monotonous and difficult mobility experiences may lead some to "miss" the city, in a tunnel-like manner. In the context of urban daily mobility practices, this paper argues that although the possibility for expanding places by daily mobility exists, increasingly urban experiences in cities like Santiago de Chile, involve a simultaneous tunneling or confining effect, reducing the possibilities of encounter and interaction, which are the essence of urban experience. Using an ethnographic approach to urban daily mobility practices in Santiago de Chile, this paper discusses how mobility relates to place making and to urban inequality and then analyzes the way place enlargement and confinement occur.     

Management Discretion and Political Interference in Municipal Enterprises. Evidence from Italian Utilities

The attention of scholars and policy-makers is shifting from full privatisation to alternative measures as a means to improve the efficiency of public services. This article focuses on three restructuring measures adopted by local governments: partial privatisation (without transfer of control rights), inter-municipal joint ventures, and the presence of outside directors on the Board. Divergent hypotheses on these measures have emerged from two economic theories, namely public choice and the agency perspective. An empirical analysis investigates the effects of restructuring processes on a sample of Italian municipal utilities. Partial privatisation has been shown to play a significant and positive role, while Board independence from management has a less significant influence. Multi-government utilities have been found to suffer from severe coordination costs, which are not outweighed by scale benefits. Our findings reveal that management discretion is a significant source of inefficiency in municipal enterprises.     

A forensic image processing environment for investigation of surveillance video

We present an image processing software suite, based on the Matlab environment, specifically designed to be used as a forensic tool by law enforcement laboratories in the analysis of crime scene videos and images. Our aim is to overcome some drawbacks which normally appear when using standard image processing tools for this application, i.e. mainly the lack of full control and documentation on the operations which have been performed on the images, and the absence of new, more sophisticated algorithms which can provide improved performances and "make the difference" in critical cases.     

Fetal Age Determination Through Biparietal Diameter: A Simple Method of Cranial Reconstruction Using Multipurpose Silicone

In forensic medicine, gestational age of fetal remains is a crucial information in several contests, but the classic methods are inadequate when early gestational age needs to be assessed. In the author's experience, the measurement of the biparietal diameter provides more accurate information for this purpose. The status of the fetal head is therefore critical. This work describes an easy technique that allows to reconstruct the cranial volume of the fetus using multipurpose silicone given both the flexibility of the fetal head structure and the inorganic nature of the silicone itself. In conclusion, the determination of the biparietal diameter achieved through the above‐described technique permitted a more accurate estimation of the dating of pregnancy in judicial cases where the fetal remains were incomplete and disrupted.     

The evaluation of human hand odor volatiles on various textiles: a comparison between contact and noncontact sampling methods

The focus of this study is to compare contact and noncontact human scent collection procedures across an array of textiles (cotton, rayon, polyester, and wool) to determine an optimized collection method for human scent evidence. Six subjects were sampled in triplicate for each textile and collection mode, and the samples were then analyzed through headspace solid-phase micro-extraction in combination with gas chromatography/mass spectrometry (SPME-GC/MS). Contact sampling with cotton material has been shown to be the collection method that yielded the greatest number of volatile compounds and the highest scent mass amounts. Through Spearman rank correlations, it was shown that an individual's scent profile is more reproducible within samples collected on the same textile type than between different materials. Furthermore, contact sampling with cotton fabric demonstrated the greatest reproducibility producing the lowest amount of type I and type II errors with 90.85% of the samples distinguished at the 0.9 match/no match threshold.     

“Tampering to Death”: A Fatal Codeine Intoxication Due to a Homemade Purification of a Medical Formulation

Many homemade tamper processes of medical codeine formulations are available on selected “forums” on the Internet, where recreational codeine users claim to be able to purify codeine by removing additives, such as acetaminophen, to avoid or limit adverse effects. In this work, it is reported and discussed a fatal case of codeine intoxication. The findings of objects such as jars, filters, and tablets, and amounts of unknown liquid material at the death scene investigation suggested a fatal codeine intoxication after the tampering procedure called “cold water extraction.” Toxicological results obtained from the analysis of both the nonbiological material and the body fluids of the decedent integrated with the information collected at the death scene investigation confirmed the above‐mentioned hypothesis. This report underlines the importance of a tight interconnection between criminalistics and legal medicine to strengthen the identification of the cause of death and the reconstruction of the event.     

The effect of antifreeze (ethylene glycol) on the survival and the life cycle of two species of necrophagous blowflies (Diptera: Calliphoridae)

Entomotoxicology involves the analysis of the presence and the effects of toxicological substances in necrophagous insects. Results obtained by entomotoxicological studies may assist in the investigation of both the causes and the time of death of humans and animals. Ethylene glycol (EG) is easy to purchase, sweet and extremely toxic. It may be consumed accidentally or purposefully, in an attempt to cause death for suicidal or homicidal intent. Several cases report fatalities of humans and animals. The present study is the first to examine the effects of EG on the survival, developmental rate and morphology of two blowfly species, (Diptera: Calliphoridae) typically found on corpses and carcasses: Lucilia sericata (Meigen) and L. cuprina (Wiedemann). Both species were reared on substrates (beef liver) spiked with three different concentrations of EG that could cause death in either a human or cat: 1/2LD₅₀ (T1), LD₅₀ (T2), 2LD₅₀ (T3), in addition to a control treatment (C) with no EG.Results of this research show that: a) both species are unable to survive if reared on a food substrate spiked with the highest concentration of EG (T3), while lower and medium concentrations (T1, T2) affect, but not prevent, the survival and the completion of the life cycle of such species; b) adults of L. sericata eclose only in C and T1, while adults of L. cuprina in both C, T1, T2; however, c) the developmental time of both species reared in T1 and T2 is statistically slower than the control; d) the body length of the immatures of both of the species reared in T1 and T2 is statistically smaller than the control.
