Diversity of dental patterns: application on different ages using the Brazilian National Oral Health Survey

Methods of individual identification using human remains are widely used in forensic anthropology; however, there are few studies that use statistical methods in order to obtain a correct definition of parameters. The objectives of the study were to verify the diversity of dental patterns in the Brazilian population and analyse its application on different ages. Data from the Brazilian National Oral Health Survey were used to verify the presence and absence of dental treatment among 35,613 individuals of several age groups: 15-19, 35-44 and 65-74. Information referring to every dental element was described: higid (H), decayed (D), filled (F), missing (M) and prosthesis (P). Coincidences that were observed in pairs of homologous teeth were analysed according to clinical situation, gender and age. Ordinary findings (presented in more than 10% of pairs) and extraordinary ones (presented in less than 10% of pairs) were described. Total and conditional diversity estimates were performed. Among adolescents, H were the most frequent teeth, and the first molar teeth were the ones presenting less frequency of H. Among adults, the frequency of M teeth among females ranged from 15.17% to 71.59%, and among males they ranged from 9.00% to 87.20%. Among the elderly, M teeth were observed in the largest frequency, and anterior teeth presented fewer losses than posterior ones. M was the condition that most coincided with both sides in the elderly. In adults, some pairs of teeth presented H, but mostly pairs of teeth presented as M. Among adolescents, there was more concordance of the H component. Among male and female adolescents, we observed extraordinary findings in DMFP dental conditions in most of the teeth. Among adults, the less frequent dental condition was P, which was found in several teeth. The extraordinary findings among elderly male teeth were codes H, D, F and P; among females, they were H, D, F and P codes. The high prevalence of healthy teeth in adolescents and a high rate of edentulism in the elderly interfered with the analysis performed. However, when an estimation of diversity that corrects those distortions was used, all of the groups presented satisfactory results that were homogeneous in the performed analysis.     

Extended PCR conditions to reduce drop-out frequencies in low template STR typing including unequal mixtures

Forensic laboratories employ various approaches to obtain short tandem repeat (STR) profiles from minimal traces (<100 pg DNA input). Most approaches aim to sensitize DNA profiling by increasing the amplification level by a higher cycle number or enlarging the amount of PCR products analyzed during capillary electrophoresis. These methods have limitations when unequal mixtures are genotyped, since the major component will be over-amplified or over-loaded. This study explores an alternative strategy for improved detection of the minor components in low template (LT) DNA typing that may be better suited for the detection of the minor component in mixtures. The strategy increases the PCR amplification efficiency by extending the primer annealing time several folds. When the AmpF?STR^® Identifiler^® amplification parameters are changed to an annealing time of 20 min during all 28 cycles, the drop-out frequency is reduced for both pristine DNA and single or multiple donor mock case work samples. In addition, increased peak heights and slightly more drop-ins are observed while the heterozygous peak balance remains similar as with the conventional Identifiler protocol. By this extended protocol, full DNA profiles were obtained from only 12 sperm heads (which corresponds to 36 pg of DNA) that were collected by laser micro dissection. Notwithstanding the improved detection, allele drop-outs do persist, albeit in lower frequencies. Thus a LT interpretation strategy such as deducing consensus profiles from multiple independent amplifications is appropriate. The use of extended PCR conditions represents a general approach to improve detection of unequal mixtures as shown using four commercially available kits (AmpF?STR^® Identifiler, SEfiler Plus, NGM and Yfiler). The extended PCR protocol seems to amplify more of the molecules in LT samples during PCR, which results in a lower drop-out frequency.     

A Bayesian Approach to Age Estimation in Modern Americans from the Clavicle*

Abstract: Clavicles from 1289 individuals from cohorts spanning the 20th century were scored with two scoring systems. Transition analysis and Bayesian statistics were used to obtain robust age ranges that are less sensitive to the effects of age mimicry and developmental outliers than age ranges obtained using a percentile approach. Observer error tests showed that a simple three‐phase scoring system proved the least subjective, while retaining accuracy levels. Additionally, significant sexual dimorphism was detected in the onset of fusion, with women commencing fusion at least a year earlier than men (women transition to fusion at approximately 15 years of age and men at 16 years). Significant secular trends were apparent in the onset of skeletal maturation, with modern Americans transitioning to fusion approximately 4 years earlier than early 20th century Americans and 3.5 years earlier than Korean War era Americans. These results underscore the importance of using modern standards to estimate age in modern individuals.     

Examining Criminal Justice Practitioners’ Views on Collateral Consequences Policy

With the recent emphasis on reentry and the reintegration of offenders back into society, both academics and policy makers have voiced concern over both the process of applying collateral consequences in a particular case and the expanding number of collateral restrictions, some of which are quite severe. Many of these restrictions create significant barriers to reintegration for offenders released from incarceration. While reforms have been proposed, there is a lack of research examining the perceptions of criminal justice actors about collateral consequences of conviction. As parties most familiar with the application of consequences in cases, and the burdens they place on involved parties, the present study surveyed practitioners in a large Midwestern state. The findings suggest that judges, defense attorneys, probation and parole supervisors, and prosecutors are troubled by the role of collateral consequences in offender reentry and are not opposed to repealing or reforming some of these policies. Further, there are significant differences between practitioner groups as to reforms that should be implemented within the state’s criminal justice system.     

Religiosity and Rebellion in Nigeria: Considering Boko Haram in the Radical Tradition

Testing social movement theory positing that radical organizations are ideologically driven at their core, but are supported by civilians who are driven by social factors, this research interrogates the disparity between radical group ideology and supporter belief set in the context of present-day Nigeria. Content analysis of randomly selected Boko Haram publications establishes the high, and increasing, levels of religiosity exhibited by the violent social movement itself. In contrast, a large-N survey of Nigerians conducted in 2012 and 2013 shows that high levels of religiosity do not significantly predict willingness to justify violence, commitment to non-state violent actors, or positive attitude toward Boko Haram among Nigerians as a whole, but rather the opposite. Given these findings, Boko Haram may be better understood within the tradition of radical extremist movements across the ideological spectrum, even while it frames its struggle as that of a distinctly religious movement.     

Attention as a Valuable Resource

Keeping up with the news and monitoring public affairs are typically considered civic obligations. Yet there is a great deal of competition for people’s limited attention. Some studies explore when people tune in to the news and what sorts of public affairs content attract our time, but these topics warrant more research. Scholars concerned with the news media’s political role must better understand what leads people to the news in the first place. The practical import of this work is pronounced in an era where news organizations struggle to make ends meet. The purpose of this essay is to categorize what we know about what motivates people to tune in to news and then to propose a research agenda for analyzing attention to public affairs content.     

The Implications of Endemic Corruption for State Legitimacy in Developing Nations: an Empirical Exploration of the Nigerian Case

There is an extensive literature on the ramifications of corruption for economic growth, as well as for democracy. Largely unexplored, however, is how corruption works to lessen government legitimacy and empower violent anti-state movements. In this article, the perception of corruption in Nigeria is considered. Noting that Nigeria must suppress the violent extremist group Boko Haram in order to continue to govern the nation, the connections between Nigerian perceptions of corruption and support for the movement are treated. Until this research, however, there existed no empirical evaluation of this relationship. Using analysis of a survey of over 10,000 Nigerians accomplished in 2012 and 2013, we show that issues of state illegitimacy and endemic corruption have contributed to Nigeria’s present security crisis by fomenting support for non-state violent actors.     

Gender Justice or Gendered Justice? Female Defendants in International Criminal Tribunals

Recent scholarship has given increasing attention to studying women’s involvement in conflict and mass violence. However, there is comparatively less discussion of the experiences of women as actors and perpetrators in conflict, and limited discussion of women as defendants in international criminal tribunals. This article explores this under-researched area. By analysing legal materials from the cases of six female defendants, this article investigates the extent to which legal discourses are shaped by stereotypes regarding femininity, conflict and peace. It identifies three gender narratives—mothers, monsters and wives—used in relation to female defendants, which highlight the incompatibility of femininity with violence, and deny women’s agency in political and military contexts. Thus, this article concludes that female defendants in international criminal tribunals are viewed through gendered lenses, and discussed in accordance with gendered themes. This gendered justice is problematic, as it reinforces patriarchal gender stereotypes, and may hinder attempts to facilitate gender justice.     

Long-term impact of family group conferences on re-offending: the Indianapolis restorative justice experiment

Objectives

The purpose of the current study is to test the long-term effect of Family Group Conferences (FGCs) on recidivism prevalence and time to first re-offense for first-time youthful offenders.

Methods

The current study builds on an experiment with a reasonably large sample (n?=?782) conducted in Marion County (Indianapolis), Indiana, USA. The current study extends this work by following the cases for an additional 10?years. To examine the empirical relationships among the variables, this study employs a two-step approach. The initial analysis, employing logistic regression, measures prevalence of re-offending based on whether the youth ever was re-arrested during the follow-up period. The second step employs Cox Proportional-Hazards Regression to examine time until first re-offense.

Results

The findings revealed that when extended to a 12-year follow-up period, there were no significant differences between the FGC and control groups in re-offending prevalence or time to re-offense.

Conclusions

An earlier study suggests that treatment group youths experienced reduced risk in the short-term and there is no evidence in the present study to suggest that youths participating in FGCs were placed at greater risk for re-offending. Given these findings and the body of research suggesting improved outcomes for victims, continued experimentation with FGCs and related restorative processes seems warranted. Future studies would benefit from blocking procedures in the experimental design in order to examine whether treatment effects are moderated by gender, race, and initial type of offense. The lack of such blocking procedures represents a limitation of the current study.
