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. 相似文献

This paper studies the interaction between the federal and state tax systems during the 1980s and, in particular, considers how the Tax Reform Act of 1986 affected state tax structure. Using a panel data set on state governments over a nine-year period, I estimate tax share equations for six categories of taxes. I find that the state personal income tax is sensitive to changes in its tax price, but find a much smaller sensitivity to changes in tax prices for the general sales tax. I then consider various reasons why the sales tax does not exhibit a sensitivity to changes in tax price and consider the implications of these results for policymakers. The regression results suggest that different income groups are concerned with different tax instruments. Moreover, the results motivate a possible benefit approach to taxation at the state level. Linking taxes, about which a particular income group is most concerned, to services received by that group might generate additional political support for state tax systems during a time when many states are facing fiscal crisis. 相似文献

Peacebuilding is a key concept in efforts to reconstruct African states emerging from conflicts. At heart, it captures the whole array of activities associated with state-and nation-building in addition to building the foundations for local ownership of these processes. Popularised by the UN Secretary-General Boutros-Boutros Ghali in the early 1990s, peacebuilding has evolved alongside peacemaking and peacekeeping in the reconstruction repertoire. This article suggests that while there is considerable scepticism about the utility of peacebuilding in contemporary conflict resolution efforts, African experiences have, since the 1990s, provided solid lessons to both local and international actors on how to rebuild states, societies, polities, and economies. 相似文献

Women in substance use treatment report rates of childhood sexual abuse and intimate partner violence that far exceed those
reported by women in the general population. Previous research with nonrandom samples of women in substance use treatment
suggests that there is a statistically significant relationship between childhood sexual abuse and intimate partner violence;
however, little is known about the mechanisms of risk between these two public health concerns among this population of women.
To address this gap in knowledge and to inform intervention strategies, this study examined direct and mediated relationships
between childhood sexual abuse and intimate partner violence risk among a random sample of 416 women in methadone treatment.
In addition to high rates of childhood sexual abuse (57.9%), intimate partner violence (lifetime prevalence, 89.7%; 6-month
prevalence, 78.4%), posttraumatic stress disorder (PTSD, 28.6%), and global psychological distress (19.5%), findings suggest
that the relationship between childhood sexual abuse and intimate partner violence is mediated by mental health problems and
that women experiencing PTSD or global psychological distress are 2.7 and 2.4 times more likely to experience intimate partner
violence than women without such experiences, respectively. Although not a mediator in this relationship, financial independence
reduced women's risk of partner violence by two-thirds. The paper includes discussion of social learning and stress and coping theories to explicate the findings and to inform intervention
strategies.
This study is based, in part, on the first author's dissertation. A previous version of this paper was presented at the Society

Basal vacuolization of renal tubular epithelial cells (so-called Armanni-Ebstein phenomenon) has been attributed to hyperglycemia causing accumulation of cytoplasmic glycogen. Review of 34 autopsy cases with significant hyperglycemia (vitreous glucose ≥ 15 mmol/L/270 mg/dL) was undertaken to determine whether there was any significant association between the degree of hyperglycemia and the severity of this morphological change (graded as 0, 1+, 2+, and 3+). No association was demonstrated. Review of the subgroup of 14 cases with terminal hyperglycemia without ketoacidosis was then undertaken to assess the effect of hyperglycemia in isolation on renal tubular epithelial cells. Vitreous glucose levels in these 14 cases ranged from 17 to 49.7 mmol/L (306-894.6 mg/dL) with a mean of 26.25 mmol/L (472.5 mg/dL) and β-hydroxybutyrate levels ranged from 0.02 to 2.55 mmol/L (0.36-45.9 mg/dL) with a mean 0.79 mmol/L (14.22 mg/dL). Not one of the latter cases displayed basal vacuolization. No relationship between basal vacuolization of renal tubular epithelial cells at autopsy and terminal hyperglycemia could, therefore, be demonstrated. 相似文献
