Psychological and behavioral adjustment in female youths with high or low psychopathic traits

The aim of the present study was to analyze the role of psychopathic traits in female juvenile delinquency. Using a sample of 236 young females from the Juvenile Detention Centers of the Portuguese Ministry of Justice and schools in the Lisbon area, a group of female youths with high psychopathic traits (n = 118; M = 15.84 years of age; range = 14–18 years of age) and a group of female youths with low psychopathic traits (n = 118; M = 15.77 years of age; range = 14–18 years of age) were formed based on the Portuguese version of the Antisocial Process Screening Device-Self-report (APSD-SR). The results showed that young females with high psychopathic traits start engaging in criminal activities and come into contact with the justice system earlier in life; exhibit higher levels of behavioral problems, conduct disorder, delinquent behaviors and serious criminality; and demonstrate lower levels of self-esteem and pro-social behavior. The importance of some variables in predicting group membership (high versus low psychopathic traits) was established through a binary logistic regression. Our findings reinforce the importance of the psychopathy construct for the early identification of potentially high-risk female youths and for the assessment of female youths who have already come into contact with the judicial system.     

Interest groups in Brazil: a new era and its challenges

This article provides general and specific insights into Brazil's developing interest group system. In doing so, it presents a theoretical foundation for understanding this group activity, past and present. The general insights of the role of interest groups under limited political participation and authoritarian regimes down to the 1980s plus the period of democracy since then, provide background for the specific insights of the article. The specifics focus on three aspects of Brazil's contemporary interest group activity: (1) utilization of a neo-institutional analytical approach for understanding the interest group environment; (2) an analysis of the types of lobbying activity that takes place in Brazil today, including a case study; and (3) an assessment of the level of development of the group system by placing it in a comparative perspective with both advanced liberal democracies and other Latin American countries. The findings show that Brazil is, indeed, taking on many of the characteristics of a developed interest group system; but its past, its political culture, its political economy, and, paradoxically, its new-found status as an international power, work to present several challenges to its group system and thus to a full democratization of the country.

Tracking plant, fungal, and bacterial DNA in honey specimens

Consuming honey can result in adverse effects owing to poisoning by bacterial (botulism) or plant toxins. We have devised a method to extract polymerase chain reaction (PCR) amplifiable DNA of up to c. 400 bp in length based on dialysis of a 15-mL honey sample for 18 h against deionized water followed by sequential extraction using phenol, phenol/chloroform/isoamyl alcohol, chloroform/isoamyl alcohol, and ether. Sequence analysis of PCR products obtained using "universal" plant, fungal, and bacterial primers targeted to the ribosomal RNA genes has allowed us to identify six different orders of plants (Apiales, Fabales, Asterales, Solanales, Brassicales, and Sapindales), two orders of fungi (Entylomatales and Saccharomycetales), and six orders of bacteria (Sphingomonadales, Burkholderiales, Pseudomonadales, Enterobacteriales, Actinomycetales, and Bifidobacteriales) in a single honey specimen.     

Personal identification by the comparison of facial profiles: testing the reliability of a high-resolution 3D-2D comparison model

Identification from video surveillance systems is frequently requested in forensic practice. The "3D-2D" comparison has proven to be reliable in assessing identification but still requires standardization; this study concerns the validation of the 3D-2D profile comparison. The 3D models of the faces of five individuals were compared with photographs from the same subjects as well as from another 45 individuals. The difference in area and distance between maxima (glabella, tip of nose, fore point of upper and lower lips, pogonion) and minima points (selion, subnasale, stomion, suprapogonion) were measured. The highest difference in area between the 3D model and the 2D image was between 43 and 133 mm(2) in the five matches, always greater than 157 mm(2) in mismatches; the mean distance between the points was greater than 1.96 mm in mismatches, <1.9 mm in five matches (p < 0.05). These results indicate that this difference in areas may point toward a manner of distinguishing "correct" from "incorrect" matches.     

Gunshot residues on dry bone after decomposition-a pilot study

Abstract: Very little literature exists concerning radiochemical and microscopic analyses of gunshot wounds in decomposed material, and even less concerning skeletonized samples; the most advanced technologies may provide useful indications for the diagnosis of suspect lesions, especially if gunshot wounds are no longer recognizable. However, we know very little of the survival of gunshot residues (GSR) in skeletonized samples. This study examined nine gunshot wounds produced on pig heads which then underwent skeletonization for 4 years, and four gunshot entries on human heads from judicial cases which were then macerated to the bone in water; the samples underwent scanning electron microscopy coupled with energy dispersive X‐ray (SEM‐EDX) analysis. Positive results for GSR were observed only in four of the nine animal samples and in all four human samples. Among the human samples, two lesions showed Pb and Sb, one lesion only Pb, and one Pb, Sb, and Ba. This pilot study showed the survival of GSR in skeletal material and therefore the crucial importance of SEM‐EDX analyses on skeletonized material. Further studies are needed in order to ascertain the role of environmental modifications of GSR.     

Voltammetric determination of Δ9-THC in glassy carbon electrode: An important contribution to forensic electroanalysis

Teeth are recently drawing attention for their potential as biological modeling investigation samples due to their ability to be collected and their slow substance metabolism. There is no active metabolism of elements after the completion of dentin. Dentin is surrounded by enamel and cementum, and is not affected by the oral environment. Therefore, the amount of trace elements in dentin may change with age, and this is considered to be a reliable biological load index. The objectives in this study are to demonstrate concentrations of elements in the dentin of healthy Japanese subjects by sex and age, and to reveal the relationship between element levels and age. 121 healthy teeth samples were extracted due to periodontal disease or orthodontic treatment. Each tooth was sliced from the crown to the root apex into 0.5-1mm thickness, then enamel, cementum, and the pulp were removed; the dentins were used as samples. The concentration of 10 trace elements (B, Mn, Co, Cu, Zn, Rb, Sr, Mo, Cd, and Pb) in the dentin was measured using inductively coupled plasma mass spectrometer (ICP-MS). The differences Co and Pb in the dentin between men and women were significant (p<0.01). Significant positive correlation was observed between B, Co, Cu, Zn, Sr and Pb concentrations in the dentin and age (p<0.001). The results of the present study suggest that human dentin is an appropriate substance for relativity with sex and age at further future research.     

Energy Security and Climate Change in the European Union,China and Latin American Relationships:Major Challenges and Areas of International Cooperation

The author discusses the subject in both ecological and political perspectives based on a most comprehensive,authoritative and updated bibliography.Hence,Latin America and the Caribbean(LAC) is as much diversified as there are sub-regions and regional organizations in geopolitical and geo-economical terms and often dialectic regarding energy security,climate change and LAC ties with Europeans and China and so is the tripartite relations with the rest of the world so far as energy security and climate cha...     

Examination of the stability and consistency of investigative interviewer performance across similar mock interview contexts

Purpose. Three studies examined the degree to which investigative interviewers' adherence to best‐practice guidelines is consistent across similar mock interviews. Method. In each study, two interviews were administered within a period of several hours. Further, group and individual stability of interviewer performance was analysed, and performance was measured by calculating the proportion of open‐ended and leading questions as well as the presence of predetermined problem behaviours. The studies varied depending on the type of interview paradigm employed. Interviewer performance in Study 1was measured in a group context where participants rotated between the role of interviewer, child respondent, and observer. In Study 2, an adult played the role of a child recalling abuse but this occurred in isolation (participants did not observe others or play the child). Study 3 was similar to Study 2 except that in each interview an unfamiliar child aged 5–7 years recalled an innocuous event. Results. Interviewer performance was relatively stable across tasks, although the strength of the relationship between measures varied across analyses. Improvement in open‐ended question usage occurred in Study 1 but not Studies 2 and 3. Irrespective of the assessment context, the dichotomous rating scale yielded greater consistency than when questions were tallied. Further, group stability overestimated individual stability. The practical implications of these findings for trainers and researchers are discussed.     

World War One Italian and Austrian soldier identification project: DNA results of the first case

We report the results of an attempt to identify the supposed remains of a famous World War I (WWI) Italian soldier who was killed in battle along the Italian front in 1915.Thanks to the availability of offspring from both paternal and maternal lineage Y-STRs and mtDNA were analysed and both showed a clear exclusion scenario: the remains did not belong to the supposed war hero.This is the first effort of identification of the remains of soldiers who perished during World War I within a multidisciplinary project aimed at the retrieval of historical and cultural aspects linked to WWI, and the systematic study of the remains of soldiers and ultimately their identification. This last step involves both Italian and Austrian laboratories.
