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

Every day, decisions are made in universities that affect students. When a decision adversely affects a particular student, what means of redress does that student have? The circumstances in which a student has a legal claim against their university are generally unclear. Courts have traditionally tended to draw a distinction between ‘purely academic’ decisions and disciplinary decisions. There has been reluctance on the part of courts to intervene in non-disciplinary decisions which involve academic judgment, for example, the grade to be given to a student's work. On the other hand, where the decisions are purely disciplinary, for example, in relation to a student's behaviour towards others or towards university property, the courts have made it clear that there is essentially no difference between this and disciplinary matters within any other public institution or organization. However, disciplinary decisions that are connected with allegations of academic misconduct, for example, cheating and/or plagiarism, have been more problematic for the courts. Historically, the debate was whether any such decision was justiciable in public law. Recently the question has also been whether an aggrieved student may succeed in a private law action against a university. The legal issues raised by university decisions affecting students have not yet been clearly resolved in all jurisdictions. Indeed, in some cases, judges have raised many more questions than they have answered. This article will review the framework for legal challenges to university decisions against a background of recent judicial attitudes in Australia, New Zealand, the UK and the US.  相似文献

The process of the intergenerational transmission of violence is not well understood. A risk and resilience model of criminal violence against women was investigated using secondary data. The sample was composed of adolescent male juvenile delinquents who had been physically abused by their parents, and who were followed up at ages 25 and 31. A series of structural equation models were fit to investigate whether dysregulated affect mediated the effects of attachment and family chaos on the adult perpetration of violence against women. These models support the hypothesis that affect dysregulation may act as a mediator. Results raise new ideas about the mechanisms by which violence may be transmitted across generations.  相似文献

What are states doing with respect to human resource practices to improve government operations? Using data collected by the Government Performance Project, this article identifies emerging trends and innovations in state personnel systems. Specifically, it provides a national comparison in the areas of personnel authority, workforce planning, selection, classification, and performance management. Results show that many states are delegating authority for personnel functions to agencies and managers, shifting their human resource missions to being more proactive and collaborative with agencies, and adopting performance management systems that integrate organizational and individual goals. In short, many states are investing considerable resources to modernize their human resource management systems.  相似文献

The use of indicators is a prominent feature of contemporary global governance. Indicators are used to compare and rank states for purposes as varied as deciding how to allocate foreign aid or investment and determining whether states have complied with their treaty obligations. This article defines the concept of an indicator, analyzes distinctive features of indicators as technologies of governance, and identifies various ways in which the use of indicators has the potential to alter the topology and dynamics of global governance. Particular attention is paid to how indicators can affect processes of standard setting, decisionmaking, and contestation in global governance. The World Bank Doing Business indicators and the United Nations Human Development Index are analyzed as case studies.  相似文献
