Impairment based legislative limits for driving under the influence of non-alcohol drugs in Norway

Bloodstains at crime scenes are among the most important types of evidence for forensic investigators. They can be used for DNA-profiling for verifying the suspect's identity or for pattern analysis in order to reconstruct the crime. However, until now, using bloodstains to determine the time elapsed since the crime was committed is still not possible. From a criminalistic point of view, an accurate estimation of when the crime was committed enables to verify witnesses' statements, limits the number of suspects and assesses alibis. Despite several attempts and exploration of many technologies during a century, no method has been materialized into forensic practice. This review gives an overview of an extensive search in scientific literature of techniques that address the quest for age determination of bloodstains. We found that most techniques are complementary to each other, in short as well as long term age determination. Techniques are compared concerning their sensitivity for short and long term ageing of bloodstains and concerning their possible applicability to be used on a crime scene. In addition, experimental challenges like substrate variation, interdonor variation and environmental influences are addressed. Comparison of these techniques contributes to our knowledge of the physics and biochemistry in an ageing bloodstain. Further improvement and incorporation of environmental factors are necessary to enable age determination of bloodstains to be acceptable in court.     

Target screening and confirmation of 35 licit and illicit drugs and metabolites in hair by LC-MSMS

A liquid chromatography-tandem mass spectrometry (LC-MSMS) target screening in 50mg hair was developed and fully validated for 35 analytes (Δ9-tetrahidrocannabinol (THC), morphine, 6-acetylmorphine, codeine, methadone, fentanyl, amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine, 3,4-methylenedioxymethamphetamine, benzoylecgonine, cocaine, lysergic acid diethylamide, ketamine, scopolamine, alprazolam, bromazepam, clonazepam, diazepam, flunitrazepam, 7-aminoflunitrazepam, lorazepam, lormetazepam, nordiazepam, oxazepam, tetrazepam, triazolam, zolpidem, zopiclone, amitriptyline, citalopram, clomipramine, fluoxetine, paroxetine and venlafaxine). Hair decontamination was performed with dichloromethane, and incubation in 2 mL of acetonitrile at 50°C overnight. Extraction procedure was performed in 2 steps, first liquid-liquid extraction, hexane:ethyl acetate (55:45, v:v) at pH 9, followed by solid-phase extraction (Strata-X cartridges). Chromatographic separation was performed in AtlantisT3 (2.1 mm × 100 mm, 3 μm) column, acetonitrile and ammonium formate pH 3 as mobile phase, and 32 min total run time. One transition per analyte was monitored in MRM mode. To confirm a positive result, a second injection monitoring 2 transitions was performed. The method was specific (no endogenous interferences, n=9); LOD was 0.2-50 pg/mg and LOQ 0.5-100 pg/mg; linearity ranged from 0.5-100 to 2000-20,000 pg/mg; imprecision <15%; analytical recovery 85-115%; extraction efficiency 4.1-85.6%; and process efficiency 2.5-207.7%; 27 analytes showed ion suppression (up to -86.2%), 4 ion enhancement (up to 647.1%), and 4 no matrix effect; compounds showed good stability 24-48 h in autosampler. The method was applied to 17 forensic cases. In conclusion, a sensitive and specific target screening of 35 analytes in 50mg hair, including drugs of abuse (THC, cocaine, opiates, amphetamines) and medicines (benzodiazepines, antidepressants) was developed and validated, achieving lower cut-offs than Society of Hair Testing recommendations.     

Permanent teeth development in a Spanish sample. Application to dental age estimation

The purpose of this study is to clarify the chronology of different stages of dental development, according to Demirjian, in a sample of Spanish children, which will enable us to build a database that will be used as a reference in regard to the dental development of individuals of our socio-geographic environment. In the same studied sample, a calculation of the dental age according to Demirjian was carried out. This study was conducted in a final sample consisting of 1010 orthopantograms, corresponding to Spanish children (485 boys and 525 girls) ages 2-16. Comparing the age of onset of the different stages among the children, evidence was found that girls had an earlier general development than boys. These differences were only statistically significant in teeth and concrete stages. The canine teeth revealed greater gender dimorphism, with significant differences in all stages compared with the upper canines. The method proposed by Demirjian for dental age calculation resulted in a significant overestimation of dental age in relation to the chronological age in boys (average of 0.87 years) and girls (average of 0.55 years). Data from this study may be used as reference for dental maturity, as well as a standard for estimating age in Spanish children.     

Allele sharing in first-degree and unrelated pairs of individuals in the Ge F I AmpFlSTR Profiler Plus database

Eleven Italian forensic laboratories participated in a population study based on the AB Profiler Plus loci with proficiency testing. The validated database, including 1340 individuals, is available on-line. Tests for Hardy-Weinberg equilibrium, gametic unbalance, and heterogeneity of gene frequency were generally not significant. Gene frequencies at each locus were consistent with those of two previously published Italian studies, but different from a third. Individuals of each subsample were paired, and the total number of alleles shared across the nine loci was determined in each pair. The analysis was replicated over the total sample. In addition, two samples of mother-child pairs (N=315) and full-sib pairs (N=91) were subjected to allele sharing analysis. The resulting distributions were sufficiently distinct from the sample of unrelated pairs as to be of practical usefulness.     

Psychosocial Adjustment and Family Relationships: A Typology of Italian Families with a Late Adolescent

The importance of family relationships in human development and adjustment has always been recognized in psychological studies. The present study aims to construct a typology of families with a late adolescent and to analyze the family relationships present in each type. The typology, constructed using family satisfaction—a global index of family functioning—as the discriminate variable, took into account eight types. This study is focused on the two extreme types of the typology: Families with adequate functioning or satisfied families and Families with inadequate functioning or dissatisfied families. These two types of families were compared according to variables such as: (a) parent-child communication and its topics and (b) the family's decision-making process on topics related to the adolescent and his/her future orientation. All subjects completed a questionnaire composed of different scales. The results show substantial differences in the two family types regarding both family functioning and the role played by mothers and fathers. Satisfied families give evidence of a better communication process than the dissatisfied ones, greater sharing between parents and adolescents and, finally, a decision-making process based mostly on sharing and support. Moreover, in satisfied families the father has the role of social mediator. In this way, he succeeds in part in restoring equilibrium to the relational imbalance in favor of mothers so typical of Italian families.     

Sex @ the End of the Twentieth Century: Some Re-marks on a Minor Jurisprudence

This article offers a re-reading of Goodrichs essay, Law in the Courts of Love. My contention here is that the idiom of love that Goodrich provides us with in this essay cannot address the complexity of sexuality and sexual politics that inhabit our contemporary technoscientific culture. In so doing, I will juxtapose his essay with Laven Berlant and Michael Warners essay, Public Sex. This article will be divided into three sections. In the first section, I will evaluate and review Goodrichs genealogical approach to law and the image of justice that arises out of his approach. The second section will be a re-reading of Goodrichs Law in the Courts of Love through feminist and technoscientific discourses. Its aim is to problematise and re-think not only the idiom of feminine justice that Goodrich offers, but also to question the presuppositions upon which his work is based, primary presuppositions surrounding issues of privacy, sexuality and sexuated rights. Finally, in the third section I will conclude by suggesting that the re-figuration of justice necessitates a re-figuration of the relationship that law has with time and space.     

Natural Mentors in the Lives of African American Adolescent Mothers: Tracking Relationships Over Time

In this study, we focused on the academic attainment of African American adolescents as they made the transition from pregnancy or recent delivery to 2 years postpartum. We examined the duration, characteristics, and effects of relationships that endured over 2 years postpartum, and the role of adolescents' mentor versus maternal support. Compared to participants who did not identify mentors at either time point, participants whose mentor relationships endured over the course of the 2-year study were more likely to have remained in school or graduated. Subsequent analyses revealed that long-term mentor relationships were characterized by weekly and, in many instances, daily interactions. Additionally, participants in long-term mentor relationships reported deriving more emotional support from their mentors than from their mothers, were more satisfied with mentor support, and indicated that this support was more important to them than maternal support.     

Legal Basis and Scope of the Human Rights Clauses in EC Bilateral Agreements: Any Room for Positive Interpretation?

It is well known nowadays that the European Community includes a so-called human rights clause into the framework agreements that it concludes with third countries. It is also widely recognised that, in virtue of the relevant provisions of the Vienna Convention on the Law of the Treaties, such a clause grants the Community a right to suspend the agreement should human rights and/or democratic principles be breached. The question to be explored in the present paper is whether, in the light of its legal basis, the clause fulfils a mere 'negative' or 'sanctioning' function or, by contrast, there is room for the pursuit of positive measures of active promotion of human rights—that is the granting of technical and financial aid. It is argued here that the clauses present an ideal starting point for the pursuit of a comprehensive human rights policy at the EU level. Such a policy should encompass positive measures in the first place, systematic dialogue in the second, and suspension or negative measures of less extent only as ultima ratio in particularly grave cases which cannot be addressed through ordinary (dialogue and aid) routes.
