The Impact of Deterrence Policies on Reckless Driving: The Case of Portugal

In this paper, we test the effect of three different criminal deterrence theory policy tools: criminal certainty, severity, and celerity of punishment. Whereas most criminal deterrence studies in this field focus on the former two components of deterrence theory, this study also examines the potential deterrent effect of the latter component. Using a time-series design with monthly data, we estimate the effects of an increase in the threat of punishment for traffic offenses resulting from a general increase in fines for traffic offenses, an increase in the probability of getting caught with a blood-alcohol concentration (BAC) level outside the legal limits, and the enactment of an “on-the-spot” fine payment policy in Portugal. We find strong evidence to support a severity effect. An increase in the statutory severity of sentence maxima for traffic violations leads to a decrease in accident and injury rates—approximately an average 0.5 percent reduction in monthly accident and injury rates. Changes in the BAC levels and the mandatory swift payment policy did not produce any convincing deterrence impact.

Suicidal hanging on high-voltage line pylon

Hanging is one of the most frequent methods for suicides among young males. This report presents two cases of suicide by hanging on pylons carrying high-voltage power lines. The male victims suffered electrocution while committing suicide. Electrocution was the cause of death in both cases, however in one case blunt force injuries from hanging contributed to death. In these two cases hanging was the intentional method of suicide and it was followed by electrocution. The cases demonstrate that scene investigation, a detailed autopsy with histology, and amamnestic data are essential in the evaluation of suicides by hanging and that the determination of the cause of death remains a challenge in investigating such cases.     

Genetic population data of 12 STR loci of the PowerPlex Y system in the state of São Paulo population (Southeast of Brazil)

Allele frequency distributions and population data for 12 Y-chromosomal short tandem repeats (STRs) included in the PowerPlex^®Y Systems (Promega) were obtained for a sample of 200 healthy unrelated males living in São Paulo State (Southeast of Brazil). A total of 192 haplotypes were identified, of which 184 were unique and 8 were found in 2 individuals. The average gene diversity of the 12 Y-STR was 0.6746 and the haplotype diversity was 0.9996. Pairwise analysis confirmed that our population is more similar with the Italy, North Portugal and Spain, being more distant of the Japan.     

The role of young adolescents' perception in understanding the severity of exposure to community violence and PTSD

This study seeks to (a) identify and measure the lifetime exposure to community violence of 137 African American and Latino middle school students from a low income neighborhood and apply numerical weights to each violent event; (b) examine the relationship between the objective severity of child self reported violence exposure and the child's subjective perception of the most bothersome event; and (c) examine the relationship between child's exposure and posttraumatic stress disorder (PTSD). Results highlight that students' designation of their most bothersome exposure to community violence did not correspond to the most severe violent event they experienced. Regression analyses reveal the weight of the most severe event explains a larger percentage of the variance in PTSD compared with the relationship to victim, level of exposure, weight of the most bothersome exposure, and cumulative weight of all exposure. This study underscores the importance of assessing a child's perception of violent events.     

Public health measures against neonatal tetanus on the island of Vestmannaeyjar (Iceland) during the 19th century

The article presents a study of neonatal tetanus on the tiny island of Vestmannaeyjar (Iceland) during the 18th and 19th centuries. At an early date, Vestmannaeyjar was known for its high levels of mortality from neonatal tetanus. This appalling mortality is analysed, inter alia, on the basis of parish registers at the individual family level. During the late 18th and early 19th centuries, more than three out of four newborns on the island died during the first 2 weeks of life. At the beginning of the 19th century, Icelandic and Danish authorities had already showed great interest in improving infant survival on Vestmannaeyjar. In 1827 a physician was appointed to the island and by the late 1840s the disease was successfully fought on the island. The achievement on Vestmannaeyjar is a good example of how the sanitary movement was able to bring about important improvements in infant survival long before the breakthrough of the bacteriological revolution.     

Duplications of the Y-chromosome specific loci P25 and 92R7 and forensic implications

In the present study, we demonstrate that two commonly used Y-chromosome single nucleotide polymorphisms (SNPs), P25 and 92R7, are paralogous sequence variants (PSVs) originating from segmental duplications and that at least one of the sequence variants in each group of loci is polymorphic. Several methodologies were used in order to detect the SNP alleles and the PSVs of the loci. All results obtained with the various typing techniques supported the conclusion. The allele distributions of the binary markers were analysed in more than 600 males with seven different haplogroups. For P25, the ancestral allele C was found in several samples from different haplogroups. The derived allele A was always present with an additional C variant. Haplogroup P was defined by the derived allele A at the 92R7 locus. However, the ancestral allele G was always associated with an A variant due to the duplication.     

Assignment of paternity in a judicial dispute between two neighbor Holstein dairy farmers

DNA profiling was used as evidence to assign paternity in a dispute between two neighbors in a judicial case of undue appropriation of cattle offspring from five alleged Holstein sires. Five offspring were genotyped using ten genetic markers (nine microsatellites and the BOLA-DRB3 locus). The computer program CERVUS was used to estimate the LOD score values and the confidence of paternity assignments. The results presented here show that three out of five paternity cases were assigned at 95% of confidence to a single sire with a LOD score ranging from 2.53 to 3.55. A fourth male was assigned using its delta value. Finally, all alleged sires were excluded from the paternity of the fifth offspring, probably due to the existence of an non-sampled male in the studied population. We concluded that the likelihood-based approach, included into CERVUS program, was a powerful tool in cattle kinship analysis when dealing with judicial dispute particularly when the dam's genotype was absent, allowing the assignments of paternity at 95% level of confidence in situations usually used by dairy and beef cattle producers in Argentine (e.g., multi-sire pasture mating).     

Prevalence and Predictors of Sexual Risks Among Homeless Youth

This study examined prevalence of sexual risks among homeless adolescents and described factors associated with those risks. Community-based outreach methods were used successfully to access this difficult-to-reach population. The sample included 203 homeless youth aged 15–22 recruited from community sites. Questionnaire items addressed demographics, sexual behaviors, alcohol/drug use, STI history and testing, and pregnancy history. In cross-sectional analysis, 58.7% of males and 75.6% of females reported recent sexual intercourse. Of those, one third of males and half of the females used no barrier method with at least one partner. Both gender (female) and race/ethnicity (non-Black) were associated with having intercourse without a barrier contraceptive method. Over one fifth reported a history of survival sex or receiving money, drugs, clothing, shelter, or food for sex. These results show disturbingly high rates of a number of sexual risks, reinforcing the need for targeted interventions with this highly vulnerable population.
