A 17-month-old male infant died at home. The infant's right arm was immobilized because of a humeral fracture 1 month earlier. The circumstances of death appeared unclear to the police investigators and a medicolegal autopsy was carried out. External examination revealed diffuse ecchymoses of varying color. Postmortem imaging was performed prior to autopsy (X-rays, multislice computed tomography [MSCT], and focused brain magnetic resonance imaging [MRI]). These investigations revealed four rib fractures of varying ages, one of which was posterior. Cerebral and pericerebral traumatic lesions were also diagnosed: bilateral subdural hematomas, intraventricular, meningeal, and interpedoncular hemorrhages. In the abdomen, fresh blood was visible within the anterior abdominal wall and the mesenteric root. Autopsy and microscopic study confirmed these lesions. This case report illustrates the valuable assistance rendered by MSCT and MRI to diagnose abuse when a child has died in unclear circumstances.  相似文献

Investigations into the causes and effects of parallel importinghave concentrated on price discrimination, but arbitrage canalso occur on non-price dimensions. Using a natural experimentin the New Zealand film distribution industry between May 1998and November 2001, we examine the effect of parallel importingon quality as it relates to the timing of the availability offilm media. We demonstrate that (a) cinema revenues were underminedas consumers substituted viewing films on parallel importedDVDs for the cinema format and (b) that studios responded tothe threat of parallel imported DVDs by bringing forward therelease of films into New Zealand cinemas. The reduced delaybetween US and New Zealand cinematic release dates is shownto be consistent with the introduction of competition when timingis a dimension of quality and choice. We conclude that parallelimportation of DVDs almost certainly resulted in a net increasein welfare in New Zealand.  相似文献

Trying to build alliances that span the divide between trade unions and NGOs as well as the divide between the North and the South might seem a utopian task. But this is exactly what an imaginative new generation of organisers from the Western hemisphere's labour movements and NGOs are trying to do. This paper analyses two very different efforts working to bridge this ‘double divide’. The first is a combination of organisations, including unions and NGOs in both North and South, that are focusing on blatant violations of the dignity of workers in apparel export processing zones in the South. This ‘basic rights complex’ has resulted in important victories. A second complex of organisations, also involving unions and NGOs in both North and South, has raised broad macro issues of governance focusing particularly on the anti‐democratic character of current proposals for a free trade area of the Americas. Neither of these complexes is without its weaknesses, but each makes it clear that bridging the double divide should be thought of not as a utopian dream but as work in progress.  相似文献

In this article, we draw on data obtained in interviews with District Judges about the factors which they say influence the exercise of their discretion in possession proceedings. Analysing the data set enabled us to create three ideal types of judicial decision—making which we have labelled 'liberal', 'patrician', and formalist'. We discuss the differences between each ideal type across five different variables: the District Judge role; approach; view of occupiers; the problem; behaviour of occupiers. Our data demonstrate a set of reasons to explain different approaches and outcomes between different District Judges (as well as the perhaps unlikely identification of a 'maverick' or 'idiosyncratic' style of judging). We conclude by suggesting on the basis of our data that, despite calls to structure or remove the discretion from District Judges, any such changes are unlikely to have much effect.  相似文献

The Committee of University Chairman publishes a code of good practice designed, among other things, to ensure clarity about the authority on which decisions are taken on behalf of universities, subordinate domestic legislation created and the exercise of discretion regulated. In Carltona Ltd.v. Commissioners of Works [1943] 2 All ER 560 AC the question was whether civil servants were acting ultra vires if they acted on behalf of a competent authority without reference to that authority. Oxford and Cambridge, which preserve an ancient system of governance by direct academic democracy, remain testbeds of this principle, for their administrators are in effect their ‘civil servants’, not their managers. This article examines the questions which are arising as both universities begin to create Senior Management Teams, and the implications for the higher education sector more widely.  相似文献
