ABSTRACT

This paper explores the teaching of legal professionalism in Ireland using interview data from the principal stakeholders in the legal profession education system including students (the trainee solicitors). The data was analysed phenomenographically in order to determine the extent to which there was variation in perceptions among these stakeholders as to what professionalism means and how best to teach or instil the notion. The findings indicate diverse perceptions among stakeholders that reflect a lack of shared understanding of professionalism and how to teach or instil professionalism. The study critically discusses the findings in light of relevant literature and concludes that a coordinated approach to understanding and fostering professionalism will help bridge this gap in perceptions and raise professional standards.  相似文献

Data Safety and Monitoring Boards (DSMBs) have been referred to as a "growth industry," and this trend continues to be fueled by recent FDA guidance and the NIH's requirement that DSMBs be employed in virtually all phase III clinical trials. The widening role of DSMBs has been sporadically questioned on ethical grounds, but growth has continued, despite the fact that many of the questions endure, unanswered, save for repeated references to safeguarding the scientific integrity of trials. This may be about to change. The recently appointed director of the Office for Human Research Protections (OHRP), Jerry Menikoff, is on record as regarding current practices — where consent forms often promise what the DSMB has been assembled to specifically not provide — as constituting fraudulent behavior. That is, a subject may inherently rely on, to their detriment, information that has been misrepresented in the consent document. In this paper, we assemble some of the enduring questions and top them off with Menikoff's tour de force to present what we hope will be a compelling argument to require that consent forms fairly represent what the DSMB will do — and not do — with trial data as they accumulate. We argue that DSMBs should be used only in rare circumstances, and question the practice of precluding principal investigators from DSMB membership, but our main thrust is to ensure that DSMBs, when used at all, are properly described in trial consent forms.  相似文献

Within the framework of the ENFSI Expert Working Group "Firearms" a proficiency test on the detection and identification of GSR by energy-dispersive scanning electron microanalysis (SEM/EDX) is carried out in a 2 years term. The latest test was performed in 2005/2006 and was denoted as GSR2005. Seventy-five laboratories from 28 countries participated in this proficiency test and submitted in total 83 independent data-sets. The participating laboratories were requested to determine the total number of PbSbBa containing particles on a synthetic test sample following their own laboratory specific methods of automated GSR particle search and detection by SEM/EDX. Furthermore size and position of the detected particles had to be reported by the laboratories and were evaluated statistically. The results were compiled by means of z-scores according to the IUPAC and EURACHEM guidelines-assessing individual laboratory achievements (inter-laboratory) as well as intra-laboratory performance-and were compared to the results of the previous proficiency test run GSR2003 (1). The comparison shows that there is a noticeable improvement in the method's detection capability.  相似文献

Poisoning may also lead to both coma and multiple organ failure, also in youngsters without a known major medical history. As not all toxic agents are routinely screened when a poisoning is suspected, it is useful to consider less frequently encountered poisons in certain cases. We describe the occurrence of asystole and multiple organ failure which occurred in a young man after a suspected tramadol overdose. The tramadol concentration on admission in the ICU was indeed 8 microg/ml (mg/l), far above the therapeutic range. Subsequently, the patient developed severe acute liver failure, finally leading to death. Post-mortem toxicology did not reveal any other poison responsible for this unfavourable course as only very high serum and tissue tramadol and desmethyltramadol concentrations were found. Only a few fatal poisonings attributable to tramadol alone, as observed in our case, have been reported. An overview of these cases is presented.  相似文献

The European Community is about to enlarge its de facto constitution by a fundamental rights charter. It is intended to become legally binding, at least in the long run. If it is, it will profoundly change the political opportunity structure between the Community and its Member States, among the Member States, among the organs of the Community and in relation to outside political actors. When assessing the new opportunities, one has to keep in mind the weak democratic legitimation of European policy making and its multi‐level character. The article sketches the foreseeable effects and draws consequences from these insights for the dogmatics of the new fundamental rights, their relation to (other) primary Community law and to other fundamental rights codes. It ends with a view to open flanks that cannot be closed by the dogmatics of the freedoms themselves, but call for an appropriate design of the institutional framework.  相似文献

A cluster of issues in the context of legaleducation shows the importance of legalsemiotics: new forms of citizenship, new ideas on e-education, the recent design ofe-educational programs that focus the featuresof institutional life, the concept of a`learning society' are this cluster's elements.Opinions of European Union Institutions stimulate to conceive modern society in thelight of these issues. It leads to theformulation of a fifth freedom in the Union,(after freedom of persons and goods, servicesand capital) which is the freedom toparticipate in a ``learning society'. Thepractice of that freedom leads to developinge-educational programs for institutionalskills.  相似文献
