Third molar development in a London population of White British and Black British or other Black ethnicity

Population differences in dental development between Black and White ethnic groups have been debated but not previously studied in the UK. Using inappropriate data for dental age estimation (DAE) could lead to erroneous results and injustice. Data were collected from dental panoramic radiographs of 5590 subjects aged 6–24 years in a teaching hospital archive. Demirjian stages were determined for left-sided teeth and third molars and data collected regarding hypodontia and third molar agenesis. Third molar development in self-assigned Black British, including other self-assigned Black ethnicity, was compared with that of self-assigned White British subjects. Data were compared for males and females in the two ethnic groups using T-tests for Demirjian Stages A–G of third molar development and Mann-Whitney tests for Stage H once a cut-off age at the maximum age for Stage G had been imposed. Third molar development occurred earlier in subjects of Black ancestry compared to those of White ancestry. While both ethnic groups showed large age ranges for every third molar stage, in female subjects these generally occurred at least 1.5 years earlier, and in males at least one year earlier. Hypodontia and third molar agenesis were more prevalent in White British, but the ethnic difference in third molar development persisted in subjects with complete dentitions. This is a large study that confirms ethnic differences in a London population, emphasises the difficulties of establishing the 18-year-old threshold using DAE, and confirms the risk of overestimating the age of individuals of Black ethnicity using White ethnic reference data.     

Soft Power: A Comparison of Discourse and Practice in Russia and China

This article compares soft power as a normative and operational construct in the Russian and Chinese political context. I examine Russian and Chinese discourse on soft power as well as the efforts of the Kremlin and Beijing to devise programmes for its implementation. I then compare and evaluate the similarities and differences in Russian and Chinese soft power strategy. The similarities between the two states indicate their joint status as authoritarian regimes with a Marxist–Leninist heritage. The differences can be attributed to their vastly disparate economic circumstances, but also to historical, social, and political factors that influence soft power policies.     

MEDIATION AND DIVORCE

This article describes the Danish system, tracing its roots from the days when the crown dealt with all matters involving the family. The role of the amtmen in granting divorce through this administrative process is described. A total of 94% of all divorces in Denmark are handled through this procedure.     

Personality differences between police and fire applicants

An increasingly common administrative policy is to combine police and fire departments into one collective unit titled something such as “Department of Public Safery”. However, in order to make such a combination, job incumbents must be able to perform the duties of both a patrolperson and a firefighter. Thus a combination of police and fire departments assumes that police and fire applicants are similar in skills, abilities, and personality characteristics. The purpose of the present study was to determine if police and fire applicants were similar in terms of personality. The results indicated that there were significant personality differences between police and fire applicants. These differences were discussed in terms of the policy of combining police and fire departments.     

Analyzing factors influencing readmission to a battered women's shelter

Factors that distinguished first admission and readmission to an emergency woman's shelter were examined using discriminant function analysis. Records from 563 women who were residents were analyzed. Results suggest that source of income, number and developmental stage of children, and prior history of physical assault are precursors of readmissions. This study was discussed in terms of improving follow-up services to former residents of emergency shelters.
