Analysis of Explosives by GC‐UV

A mixture of explosives was analyzed by gas chromatography (GC) linked to ultraviolet (UV) spectrophotometry that enabled detection in the range of 178–330 nm. The gas‐phase UV spectra of 2,4,6‐trinitrotoluene (TNT), 2,4‐dinitrotoluene (DNT), ethylene glycol dinitrate (EGDN), glycerine trinitrate (NG, nitroglycerine), triacetone triperoxide (TATP), and pentaerythritol tetranitrate (PETN) were successfully recorded. The most interesting aspect of the current application is that it enabled simultaneous detection of both the target analyte and its decomposition products. At suitable elevated temperatures of the transfer line between the GC instrument and the UV detector, a partial decomposition was accomplished. Detection was made in real time and resulted in overlaid spectra of the mother compound and its decomposition product. Hence, the presented approach added another level to the qualitative identification of the explosives in comparison with traditional methods that relies only on the detection of the target analyte. As expected, the decomposition product of EGDN, NG, and PETN was NO, while TATP degraded to acetone. DNT and TNT did not exhibit any decomposition at the temperatures used.     

The Association between Maternal Exposure to Intimate Partner Violence and Emotional and Behavioral Problems in Spanish Children and Adolescents

This correlational cross-sectional study was designed to investigate whether the intimate partner violence (IPV) suffered by mothers (physical and psychological maltreatment), the neglect suffered by children, and the maltreatment (physical and psychological) directly suffered by children are statistically associated with an increase in the probability of the child’s suffering psychopathological problems. The sample consisted of 189 Spanish children aged 6 to 17 and their mothers, recruited from Centers of Specialized Assistance for Women Victims of IPV. The results of a canonical correlation analysis showed that the most significant problems suffered by the children were both externalizing and internalizing ones. In girls, the maltreatment suffered by their mothers was directly related to a larger frequency of somatic complaints than in boys. In addition, physical maltreatment to the mother and emotional maltreatment suffered by the child exhibited a statistically significant relationship with aggressive behaviour, thought problems, rule-breaking behaviour, attention problems, and withdrawn-depressed.     

A Morphological and Morphometric Study of Bite Marks Caused by Mice (Mus Musculus) on Different Baits for Forensic Purposes

In animal bites, the dental attributes can be fundamental in identifying the marks made by various species on different matrices. Although rodent bite marks have been studied in the context of postmortem interference, little research has used different baits to analyze these marks linking not only specific behavior patterns but also the possibility of structural damage. Twenty mice (Mus musculus) were exposed to different baits to study their bite marks in a controlled model. The known pattern of parallel and multiple grooves has been seen in all baits, but polyvinyl chloride and fiber‐optic cable were significantly different between each other and the other baits. Some baits showed patterns of anchorage of the upper incisors and space between the lower incisors when gnawing. This technical note represents a novel model of analysis where veterinarians and/or dentists may be asked to give an opinion on alleged animal bite marks.     

Legislative Parties in Volatile,Nonprogrammatic Party Systems: The Peruvian Case in Comparative Perspective

This article extends the analysis of political parties in electorally volatile and organizationally weak party systems by evaluating two implications centered on legislative voting behavior. First, it examines whether disunity prevails where weakness of programmatic and electoral commonalities abound. Second, it analyzes whether inchoate party systems weaken the ability of government parties to control the congressional agenda. The empirical analysis centers on Peru, a classic example of a weakly institutionalized party system, and how its legislative parties compare to those of Argentina, Brazil, Chile, and the United States. The results lend support to the view that lower unity characterizes weakly institutionalized settings. The agenda‐setting power of government parties, however, appears to be influenced more by the majority status of the government than by the level of party system institutionalization.     

How do citizens attribute responsibility in multilevel states? Learning,biases and asymmetric federalism. Evidence from Spain

Recent empirical evidence suggests that decentralization challenges the stakes of democratic control by blurring responsibility attribution between levels of government. Exploring the implications of decentralization on accountability requires a better understanding of the conditions under which decentralization affects clarity of responsibility. The theoretical claim in this article is that these conditions are related to the particular design and duration of decentralization arrangements. To test this proposition, individual data from a system where decentralization varies both in design and duration – the Spanish State of Autonomies – are used. Results show that clarity of responsibility has worsened where decentralization has adopted a more intertwined (marble-cake) design and that individuals may “learn” on responsibility attribution the longer they experience a particular distribution of competences.     

Forensic Facial Approximation: Study of the Nose in Brazilian Subjects

Forensic facial approximation is an auxiliary method for human identification and allows facial recognition. The midface, that includes the nose, is vital for the recognition of a familiar face. The purpose of this study was to set hard tissue parameters to estimate nasal width, to test the method to estimate nasal width of Brazilians, and to analyze the relationship between nasal profile and facial type. A total of 246 computed tomography scans (183 females and 63 males) of adults were analyzed in Horos. Bone tissue measurements and facial type classification were performed on the skull scan. Nasal profile morphology was accessed through the tool 3D surface rendering. There was a difference around 3 mm from real to predicted nose through the method to estimate nasal width in Brazilians. So, the method may be used in forensic practice. Straight nose was associated with long face type.     

How pedophilic men think about adult-child sex: effects of child gender and physical maturity

To date, very little research has tackled whether pedophilic men’s attitude towards adult–child sex depends on characteristics of the adult or the child involved in such acts. This study examines the effect of the child’s gender (male vs. female) and physical maturity (pre-pubescent vs. early pubescent) on the moral evaluation of apparently noncoercive adult–child sex in a 2?×?2 factorial online vignette experiment. One hundred eighty-three English-speaking pedophilic men rated their agreement with moral arguments on the Immoral Sex Scale, as well as whether they believed this behavior to be typical for a child. The results revealed considerable inter-individual differences, with about one third showing restrictive moral attitudes. Contrary to our expectations, gender and physical maturity neither affected the perceived morality of the sexual act, nor beliefs about the representativeness of the child’s behavior. However, when controlling for confounds, pedophilic men believed that boys were more likely to willingly engage in adult–child sex. Furthermore, participants with stronger liberal attitudes were found to be more likely to defend the sexual act, as were participants with a preferential interest in pre-pubescents. There was no link between attitudes towards adult–child sex and sexual offending, replicating the non-associations reported in previous community surveys.     

Validation of neuropsychological consequences in victims of intimate partner violence in a Spanish population using specific effort tests

Neuropsychological consequences in female survivors of intimate partner violence are being used in courts as evidence of acquired injury and for criminal exculpation. To support the validity of neuropsychological test performance and the veracity of victim testimony, effort tests can be used by expert witnesses. Nevertheless, no study has evaluated whether the two principle types of effort tests, Symptom validity tests or Performance validity tests, are most adequate for this population. The study’s objective was to compare the false positive rates of a Performance validity test (Test of Memory Malingering: TOMM) and a Symptom validity test (Structured Inventory of Malingered Symptomatology: SIMS). The sample included 68 female intimate partner violence victims and 40 control females. SIMS showed a significantly higher rate of false positives in victims on four of five subtests, reaching a 59.3% in the total score. There were 0% false positives in both groups on the TOMM. Findings indicate that the SIMS may incorrectly score female IPV victims, undermining the victim’s testimony in judicial cases.     

“<Emphasis Type="Italic">Peer effects</Emphasis>” or “<Emphasis Type="Italic">quasi</Emphasis>-<Emphasis Type="Italic">peer effects</Emphasis>” in Spanish labour court rulings

The current work seeks to ascertain whether rulings on dismissal cases issued by incumbent judges in Spanish labour courts are influenced by whether they are acting alone in their own court or sharing duties with other judges such as replacement judges, support judges or incumbent judges from other courts. We consider that a court is treated when more than one judge rules in it. Then, an analysis is conducted so as to determine the effect of such a treatment on the percentage of cases ruled in favour of the dismissed worker. The data used in the research are taken from the information recorded at court level provided by the statistics kept by the General Council of the Spanish Judiciary. A total of 2888 observations were available, corresponding to the period spanning 2004 to 2012. As regards the findings, it may be concluded that there is a significant positive impact on the number of dismissal cases ruled in favour of workers when incumbent judges are not acting alone in their court, particularly when the incumbent judge solves cases together with another professional judge.
