Factors affecting postmortem tooth loss

Unassociated human bones are a particular problem during the exhumation of mass graves and a factor that limits anthropological and paleopathological analyses from archaeological contexts. Extensive anthropological literature has focused on the complex taphonomic factors that influences bone assemblages, but little attention has been paid to postmortem tooth loss and factors affecting this process. The following study focuses upon the influence of different factors on postmortem tooth loss. Three samples were investigated in the study: a medieval church cemetery containing 110 individual skeletal remains, and two samples from a series of mass graves made within the same time period in 1999, containing 402 bodies. The frequency of postmortem tooth loss was analyzed relative to postmortem interval for each sample, excavation methods, age distribution, and presence of bone loss associated with periodontal disease. Our results indicate that the degree of alveolar bone loss significantly affected both antemortem and postmortem tooth loss and that the frequency of postmortem tooth loss has the strongest correlation to time since death. These findings suggest that additional care should be taken when exhuming remains from older contexts.     

The Effect of Intellectual Disability on Children's Recall of an Event Across Different Question Types

This research examined the performance of 80 children aged 9-12 years with either a mild and moderate intellectual disability when recalling an innocuous event that was staged in their school. The children actively participated in a 30-min magic show, which included 21 specific target items. The first interview (held 3 days after the magic show) provided false and true biasing information about these 21 items. The second interview (held the following day) was designed to elicit the children's recall of the target details using the least number of specific prompts possible. The children's performance was compared with that of 2 control groups; a group of mainstream children matched for mental age and a group of mainstream children matched for chronological age. Overall, this study showed that children with either a mild or moderate intellectual disability can provide accurate and highly specific event-related information. However, their recall is less complete and less clear in response to free-narrative prompts and less accurate in response to specific questions when compared to both the mainstream age-matched groups. The implications of the findings for legal professionals and researchers are discussed.     

Using state-level simulations in a political economy model of US trade policy

Most analyses of US congressional votes on trade policy identify political and economic factors, and general economic conditions as significant factors. In this paper we examine whether simulated state-level impacts of trade policy changes obtained from an applied general equilibrium model explain recent US Senate votes on trade bills. We find that simulated gross state product effects are good predictors of recent trade-policy votes. Our model-based measures of trade sensitivity perform slightly better in statistical terms than the more traditional economic measures. For the Senate as a whole, import considerations have a larger impact on senate voting than export considerations.     

Legal Responses to the Standard Form Contract of Employment

Having suggested that the advent of standard form contractsof employment is a neglected aspect of employment law, an assessmentis made of two of the main legal responses to the potentialunfairness of terms, namely implied terms and the applicationof section 3 the Unfair Contract Terms Act 1977. The Law Commission'sproposed legislative reform is also examined. It is concludedthat only by combining terms implied by the law with the statutoryprotection of reasonable expectations of employees will thelaw succeed in devising an adequate technique for rebalancingcontracts of employment.     

A comparative analysis of general strain theory

Purpose

Since its introduction in 1992, general strain theory (GST) has garnered much empirical support. The large share of this support, however, derives from studies conducted in the United States. There is little comparative research on GST, particularly research that examines the effect of the same or similar strains on crime across countries. Thus, we know little about the generalizability of GST. This study attempts to fill this gap by testing GST in five different cities across Europe: Bucharest in Romania, Sofia in Bulgaria, Riga in Latvia, Kaunas in Lithuania and Reykjavik in Iceland.

Methods

We examine the relationship between five strain measures and violent- and property crime among samples of adolescents in each city using regression techniques.

Results

The data are generally supportive of GST, with most of the strains having significant associations with property and violent crime in all or most of the cities.

Conclusion

GST is generalizable to a range of European cities. Implications and examples for future comparative research on GST are discussed.     

The use of crossover immunoelectrophoresis to detect human blood protein in soil from an ambush scene in Kosovo

This study examines the survivability of human blood proteins in soils from a year and a half old ambush scene in Kosovo. A total of 72 soil samples were collected, a number of which were directly associated with bone fragments or bullet projectiles. The samples were examined using crossover immunoelectrophoresis (CIEP) to determine the presence of blood protein and species affiliation. Human blood proteins were identified in 44 of the 72 samples (61%) with the majority of the positive observations (29 of 44) found 0.0-4.5 cm below ground surface (65%). Chi-squared and two-sample difference of proportions tests confirmed significant differences between samples with and without associated physical evidence and the presence and depth of human blood proteins. While DNA has largely replaced immunological analysis in forensic analyses, our results suggest that in particular situations, CIEP may still be a valuable tool in criminology.     

Trump's North Korea Bluster Has Shattered US Standing As Global Leader

The more stridently Trump says he is going to stop North Korea, the worse it looks when he fails, and the more Beijing stands to gain.
