Abstract A number of major organisations have, over the last five years or so, become involved in offering advice on the taking and use of photographs of children. The Information Commissioner's Office, for example, has issued guidance on the legal situation surrounding the photographing of children and the NSPCC has drawn up recommendations, for community groups, concerning the placement of children's photographs on websites. 相似文献

Great Britain has a long and varied experience of dealing with terrorism, spanning some 400 years from the time of Guy Fawkes. This experience ranges from dealing with small anarchist groups in the 1800s, full counter-insurgency campaigns fought during the withdrawal from Empire in the 1940s and 1950s and the long running efforts to stop violence associated with Northern Ireland. Such a varied nature of threats means that the British response has been continually adapted at policy, legislative and policing levels. Despite this adaptation and change, there seems to be a constant theme running throughout the history of British counterterrorism. 相似文献

Law enforcement agencies and institutions of higher education have confronted increasing numbers of violent and destructive campus riots and disturbances over the past decade. Problematic is the fact that these riots typically have no underlying cause, other than students’ quest for excitement. Responding to gaps in the empirical literature about these events, this study used data from two waves of surveys to systematically examine those involved in a recurring problem event in a college town that was subject to a police crackdown. The analyses drew on survey responses from over eight hundred event participants in 2002 and 2003, and the results revealed that increased enforcement had a significant effect on crowd composition, including the gender and race of participants, repeat visitors, out-of-town participants, and perceptions about the subjects' overall experience. Implications for law enforcement and community strategies to decrease the size and destructiveness of such problem events are outlined. 相似文献

A novel ring-substituted methamphetamine regioisomer, N,alpha,4-trimethyl phenmethylamine, was synthesized in order to study the validity of proposed structures for various mass spectrometry (MS)-derived peaks in a methamphetamine fragmentation pattern. While other research efforts have studied aspects of methamphetamine in detail, a full fragmentation study has not been reported previously. In addition to showing molecular structures represented by fragment peaks, mechanisms for selected processes are detailed. An empirically derived procedure to easily determine by simple spectral peak pattern recognition the geometry of dimethyl- or ethyl-substituted immonium ions (RRC = N+ RR) where m/z = 58 is outlined. These results are platform independent for electron ionization (EI) instruments, but have also proven to be helpful in explaining spectral peaks observed in spectra from ion trap systems. The spectrum for the synthesized methamphetamine regioisomer was accurately predicted using this methodology. While this approach is useful in some casework, the converse may be more useful: when an unexpected or unusual peak pattern arises in a spectrum, being able to analyze it to determine the structure of the molecule. This paper gives an analyst the means to begin such retro-synthetic analyses. 相似文献
