The emergence of mobile phones with built-in digital cameras is creating legal and ethical concerns for school systems throughout the world. Users of such phones can instantly email, print or post pictures to other MMS1 1. MMS stands for Multimedia Messaging Services. MMS is frequently used to send photos from camera phones to other MMS phones or email addresses. View all notes phones or websites. Local authorities and schools in Britain, Europe, USA, Canada, Australia and elsewhere have introduced outright bans on their use because of the problems or risks they pose if misused. Risks concerned with pupils surreptitiously photographing other pupils in changing rooms or photographing examination papers are obvious examples. The article examines some worldwide examples of the misuse of camera phones in schools and the issues and problems that emerged. A landmark decision concerning the European Data Privacy Directive (Directive 95/46/EC) in the case of Bodil Lindqvist by the European Court of Justice is explored and the implications for camera phones considered. The article concludes by stating that because of their ubiquity and social potency, it is probably a mistake and an overreaction for education authorities or schools to introduce blanket bans on the possession of camera phones. Rather they need to devise sensible agreements and policies on camera phone usage.  相似文献

Eyewitness Identification in Actual Criminal Cases: An Archival Analysis   总被引:3,自引:0,他引:3  
This study analyzed 271 actual police cases in order to address several prevalent issues in the eyewitness literature. Suspect identification (SI) rates were obtained for 289 photographic lineups, 258 field showups, 58 live lineups, and 66 lineup identifications preceded by earlier identifications. SI rates were assessed for 3 levels of extrinsic evidence: no extrinsic evidence, evidence of minimal probative value, and evidence of substantial probative value. The SI rates for the photographic lineups were assessed as a function of delay, same vs. cross-race conditions, witness type, and weapon presence. SI rates declined significantly over time; SI rates were significantly greater for the same-race condition. SI rates were much greater for field showups than photographic lineups, 76% vs. 48%. The SI rates for the field showups did not vary as a function of eyewitness conditions. The relation between confidence and suspect/foil identifications for the live lineups was significant and moderately high. The utility of archival identification studies for eyewitness testimony research is discussed.  相似文献

This article argues that the way EU competences are defined plays an important role in the social legitimacy problems of the EU. The fact that its powers are purposive compels the EU to privilege narrow functional goals and act in a highly focused way. This has the consequence that politics cannot be meaningful within the EU, since essential choices of direction are pre‐empted. It also has the consequence that EU law is over‐instrumental and lacks expressive qualities, alienating the public. Now that EU law is so broad, the same defects are being imposed increasingly on Member States. Without another form of conferred power, the legitimacy of the EU, and of law and government in Europe, will be increasingly undermined. The constitutional DNA, which has been a functional success for Europe, may also be its political nemesis.  相似文献

Abstract:  Removing all nationality discrimination means treating the emigré national like a foreigner, not just treating the foreign resident like a national. This challenges directly the idea that the national enjoys a permanent bond with his home country, wherever he may go. It also ushers in residence as an alternative to nationality as the criterion for membership of society and rights to benefits. This makes national solidarity a less discriminatory affair, and so easier to defend legally. One result may be tighter, in some ways less open societies. Yet membership of these societies will be voluntary and temporary and open to all. This argument is developed through a critical examination of recent judgments from the Court of Justice on residence conditions in national law.  相似文献

With pressure on universities to better contribute to society, academic entrepreneurship is an increasingly recognised source of new knowledge and technologies as well as being a driver of the movement to a knowledge society. However, whilst growing, the level of academic entrepreneurship in Europe is still relatively low. Two reasons that are factors influencing this are inhibitors (barriers) and facilitators (drivers), however the understanding of how their interplay influences academic entrepreneurship, particularly across different context is lacking. For this reason, this study focussed on two environmental settings, European regions and countries, seeking to understand if it is the hurdle (barrier) or (and/or) tail-wind (drivers) that most impacts academic entrepreneurship and how does the regional or national context influence this. An online survey was translated into 22 languages and undertaken in 33 countries in Europe and the European Economic Area. From the original data set, 12 countries in four European regions provided a sample of 2925 responses, with a second step to focus on four ‘lead’ countries within those regions. The results show that there is a significant difference in the university-business cooperation barriers and drivers that effect academic entrepreneurship in the European regions. Furthermore, different barriers and drivers were found to significantly affect the four lead countries with barriers and drivers being able to provide a good explanation of the extent of academic entrepreneurship in the UK and Germany, and a limited explanation of entrepreneurial activity by Spanish and Polish academics. Overall the article contributes to the literature of resource-based theory and also the understanding of factors influencing European academic entrepreneurship.  相似文献

The detection of DNA is inhibited in cases of sexual assault involving condom use. Trace evidence, including condom lubricant residues, provides crucial associative evidence in such cases. The existing Fourier transform infrared spectroscopy (FTIR) methods for lubricant analysis and detection are limited with regard to sensitivity and discrimination. The aim of this research was to establish a new method as an alternative to FTIR for the analysis of condom lubricant residues. Pyrolysis gas chromatography-mass spectrometry (PyGC-MS) and GC-MS are highly sensitive methods of analysis for a wide range of chemical substances. PyGC-MS and GC-MS were used to analyze condom lubricants in standard solution, from clean swabs and from postcoital swabs. Pyrolysis of polydimethylsiloxane (PDMS) lubricant forms cyclic products known as cyclic dimethyl siloxanes (DMS), which are separated and detected by the GC-MS. The polyethylene glycol (PEG) lubricant can be analyzed by GC-MS directly from solution. The methods of extraction and analysis presented in this paper were shown to be significantly more sensitive than FTIR for the analysis of PDMS and PEG condom lubricants. PDMS was detected as low as 1 mug in standard solution and from clean swabs using the PyGC-MS method. PEG was detected as low as 0.5 microg from standard solution and 50 mug from clean swabs using the GC-MS method. Unfortunately, we were unable to provide further discrimination between condom brands and subbrands. The methods established throughout the research were used successfully to detect condom lubricants from donated postcoital swabs. Lubricants were detected in abundance on swabs 12 h postcoitus. Recommendations are made regarding implementation of new methods for routine analysis of casework samples along with strict pyrolysis interpretation criteria to minimize the possibility of misinterpretation of false positives.  相似文献

This paper systematically examines intra-organizational consensus of perceptions of managerial reform in local government in the UK. The paper questions the role of 'elite surveys' in public sector evaluation research by exploring the extent to which multiple informants agree on the expected impacts of Best Value. Results from a survey of 978 local government officers in 80 local authorities indicate modest levels of consensus. These findings suggest that single respondent surveys are likely to produce unreliable data and misrepresent the impact of public sector policy reforms. Rather than rely on the perceptions of one respondent it is argued that multiple respondent surveys should be employed if rigorous and reliable data are to be used in providing evidence-based policy recommendations for reform in public sector organizations.  相似文献
