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.     

A Cross-Cultural Assessment of Posttrauma Reactions Among Malaysian and US Women Reporting Partner Abuse

Information on partner abuse in women from non-Western cultures and resulting psychological morbidity are scant. The present study examined these issues among women who experienced partner violence and sought refuge at a domestic violence shelter in Malaysia. These women completed a semi-structured interview and standardized measures to assess posttrauma morbidity. Responses by Malaysian shelter residents were compared with a sample of US women who also reported partner violence. The majority of women in both samples reported severe levels of distress and met criteria for posttraumatic stress disorder (PTSD). These findings suggest that psychological problems that women face after partner abuse may be similar in many respects, despite political, geographical, or cultural differences.     

Common problems and coping strategies reported in childhood and early adolescence

This research investigated problems commonly experienced by children and young adolescents, and the strategies they use to cope with these events. Six hundred seventy-six children, ages 9–13 years, were asked to identify a problem they recently experienced and to describe the strategies they used to cope with it. In addition, they were also asked to complete a scale describing how they coped with a common problem (being grounded by parents). In general, we found that children reported four common Stressors: parents, siblings, school, and friends. These Stressors were the same across age and sex; however, the coping strategies employed differed by age and type of problem. Both age and sex effects were found in reported use of coping strategies to deal with being grounded by parents. The results of this study suggest that more research must be performed to offset the lack of data in the area of children's normative coping. The implications of the findings for clinical assessment and treatment of children are discussed.He has a Ph.D. in clinical psychology from Virginia Commonwealth University.

Intra-provincial fiscal decentralization,relative wealth,and healthcare efficiency: Empirical evidence from China

Decentralizing fiscal power to locally elected governments is often regarded as beneficial for public service efficiency. However, questions remain about whether decentralizing fiscal responsibilities work well in countries lacking political decentralization. In China, fiscal decentralization has significantly strengthened the role of local governments in the provision of healthcare services, but evidence of its efficiency effects is scarce. To cast light on this issue, this study investigates the relationship between intra-provincial fiscal decentralization and the productive efficiency of healthcare services in China. Analysis of panel data for 2006–2017 suggests that expenditure and revenue decentralization from provincial to sub-provincial governments significantly improves healthcare efficiency. Further analysis suggests that the positive impact of healthcare expenditure decentralization on healthcare efficiency may be stronger in wealthier provinces. These findings have important theoretical and practical implications.
