The Reliability of Chronological Age Determination by Means of Mandibular Third Molar Development in Subjects in Croatia*

Abstract: The aim of this study was to determine the development of the mandibular third molar and its relation to chronological age. The evaluated material consisted of 979 orthopantomograms of patients of Croatian Caucasian origin aged between 5.7 and 14.6 years. Third molar developmental stages were evaluated according to the stages proposed by Nolla. The frequencies of different stages of mineralization and the mean value of the mineralization of the mandibular third molars with regard to age, gender, and size of the mandible were determined and the coefficient of correlation determined between the age of the subject and the stage of development of the mandibular molars. Statistically significant correlation was determined between mineralization of the mandibular third molar and chronological age of the subjects (boys, mandibular left third molar r = 0.779, right third molar r = 0.793; girls, mandibular left third molar r = 0.746, right third molar r = 0.725). It can be concluded that the accuracy of age estimation based on Nolla’s method is applicable for Croatian children.     

Tax amnesties, justice perceptions, and filing behavior: a simulation study

A simulation study demonstrates the influence of perceived justice of a tax amnesty on subsequent tax compliance. In addition, it investigates how the amnesty is perceived to serve the punishment objectives retribution (i.e., giving offenders what they "deserve") and value restoration (i.e., restoring the values violated by tax evasion). Hierarchical regression analysis revealed the expected positive influence of justice on subsequent tax compliance. However, when the influence of punishment objectives was controlled for, the influence of justice disappeared, while retribution and value restoration showed positive effects on post-amnesty tax compliance.     

Forensic casework analysis using the HVI/HVII mtDNA linear array assay

The mitochondrial hypervariable regions I and II have proven to be a useful target for analysis of forensic materials, in which the amount of DNA is limited or highly degraded. Conventional mitochondrial DNA (mtDNA) sequencing can be time-consuming and expensive, limitations that can be minimized using a faster and less expensive typing assay. We have evaluated the exclusion capacity of the linear array mtDNA HVI/HVII region-sequence typing assay (Roche Applied Science) in 16 forensic cases comprising 90 samples. Using the HVI/HVII mtDNA linear array, 56% of the samples were excluded and thus less than half of the samples require further sequencing due to a match or inconclusive results. Of all the samples that were excluded by sequence analysis, 79% could be excluded using the HVI/HVII linear array alone. Using the HVI/HVII mtDNA linear array assay, we demonstrate the potential to decrease sequencing efforts substantially and thereby reduce the cost and the turn-around time in casework analysis.     

Justice of Conjugal Divisions of Labor—You Can't Always Get What You Want

The new intramarital distributions of 190 young parents in their third month of first parenthood were studied in a multifaceted distributive and procedural justice framework. For a large majority, justice was an important dimension in their intramarital distributions of household labor, child care, leisure time, breadwinning. Justice ratings of various principles in general were more liberal than the reported practice, in women even more than in men. The practice reported was mainly traditional, with a gender-segregated distribution of labor. A pattern of marked consistencies and inconsistencies between the principles rated as just and factual practice emerged. Inconsistencies occurred more often in women than in men.     

Analysis of Mitochondrial DNA from a Burned,Ninhydrin‐Treated Paper Towel

Contact‐based evidence is likely to have limited quantities of DNA and may yield mixed profiles due to preexisting or contaminating DNA. In a recent arson investigation, a paper towel was collected and used as circumstantial evidence. The paper towel was partially burned and was likely set on fire with flammable liquid. As part of the investigation, the paper towel was treated with ninhydrin to visualize fingerprint evidence. Initial DNA analysis of two swabs was negative for short tandem repeat (STR) markers and revealed a mixture of mitochondrial DNA (mtDNA). Analysis of 13 additional cuttings yielded four more mixed profiles, but also two samples with a common single‐source profile. The single‐source mtDNA profile matched that of the primary suspect in the case. Thus, even if initial mtDNA analysis yields a mixed profile, a sampling strategy involving multiple locations can improve the chance of obtaining valuable single‐source mtDNA profiles from compromised evidence in criminal casework.     

The Words of Violence: Autobiographical Narratives of Abused Women

Personal narratives tell the stories of people’s lives as well as provide insight into the meaning of those experiences. These narratives both reflect and are influenced by the relationships within which an individual is embedded. In this study, autobiographical narratives for two groups of women were compared: women who had experienced habitual gender-based domestic violence in their couple relationships and women who had not. The language of narratives was analyzed by LIWC (Language Inquiry and Word Count procedure). Results showed that the language and structure of narratives by women with a history of domestic violence indicated greater stress and trauma, more incoherent space-time organization, and poorer relationship quality. Women who experienced violence wrote longer narratives that contained proportionately more negative emotion words and more references to cognitions and physical/body issues, and indicated more disorganized structure by means of incoherent use of verbal tense, more impoverished use of connectives, and greater use of negative sentence syntax and discrepancy words. They also included proportionately more pronoun references to ‘I’,‘You’,’ and ‘He’, indicating self vs. partner conflictual relationships. However, women who had experienced relationship violence for longer decreased their references to the emotions of fear and anxiety, suggesting adaptation to violence over time.
