UK moves towards electronic commerce bill

After a lengthy gestation the UK government issued a consultation paper in March 1999 in an attempt to deal with some of the complex and important issues which will affect the development of electronic commerce, in particular the regulation of encryption and digital signatures. John Worthy and Grant Anderson outline the main topics covered by the consultation paper, look at some of the concerns facing government, industry and individual users and give an update on the progress of the proposed legislative measures.     

Passengers of Memory: Constructions of British Immigrants in Post-Imperial Australia

Based on broad research investigating British immigrants in post-Second World War Australia, this article examines various impacts of the passing of imperialism on this group, tracing how they have been "passengers" both of national memory in Australia and more recently of their own narratives. Arguing also that British migrants have been subject on occasion to postimperial forgetting, it is emphasised here that British migrants display heterogenous constructions and negotiations of identity that may reflect new departures.     

Prior similar acts in prosecutions for rape and child sex abuse

Conclusion The final question raised by the Bush administration proposal is whether its adoption would inevitably undermine the general rule limiting the introduction of prior acts. Of course, the proposal is limited on its face to prior acts of rape and child sex abuse, and the arguments based on greater likelihood of repetition are by their nature applicable only to a limited class of offenses. However, the doctrine of chances argument is applicable to any offense, and it has the potential to override the traditional rules strictly limiting the introduction of prior acts evidence.This article was originally presented at the Society for the Reform of Criminal Law Conference on Reform of Evidence Law, Vancouver, British Columbia, Canada, August 3–7, 1992.B.A., University of Michigan 1971; J.D., University of Michigan 1974.

Classical stimulants in Dallas County: A retrospective review of toxicological,seized drug,and demographical data from 2017 to 2022

Cocaine and methamphetamine remain highly abused drugs in the United States due to their euphoric effects. This study examines classical stimulant casework, defined as cases positive for methamphetamine and/or cocaine, received by the Toxicology Laboratory and the Drug Analysis Laboratory at the Dallas County Southwestern Institute of Forensic Sciences from local law enforcement agencies and/or the Office of the Medical Examiner (OME) between January 1, 2017, and December 31, 2022. Methamphetamine positivity increased from 10.4% to 20.3% in the Toxicology Laboratory over the 6 years, whereas cocaine positivity remained relatively stable at approximately 17%. Similarly, in the Drug Analysis Laboratory, the methamphetamine positivity rate changed from 24.8% to 33.2%, whereas cocaine identification remained stable at approximately 20%. Blood concentrations of methamphetamine in OME cases ranged from 10.1–42,740.0 ng/mL while they were lower in DWI casework ranging from 10.2–2385.0 ng/mL. The blood concentration trends of cocaine were similar to methamphetamine, with OME casework ranging higher (10.0–24,501.0 ng/mL) than DWI casework (10.2–371.6 ng/mL). Polydrug use was evident for both methamphetamine and cocaine in postmortem cases, and the top three most frequently co-occurring drug/drug class were opioids/opiates, cannabinoids, and ethanol. The results from this study aid in the understanding of historical usage trends of cocaine and methamphetamine in Dallas County and how those trends have changed over time as newer stimulant drugs have emerged.     

The present and future of public sector extension in Africa: contracting out or contracting in?

Public sector extension has come under increasing pressure to downsize and reform. Contracting out—the use of public sector funds to contract non‐governmental and private service providers—is often held up as a potential tool in reform efforts. Much has been written about the possible advantages of contracting out of agricultural extension and it is being encouraged and promoted by numerous international organizations. However, a look at field experience in Africa shows that contracting out is relatively infrequent, especially compared with the reverse—contracting in—where private sector and non‐governmental organizations finance public sector extension delivery. Case studies from Uganda and Mozambique indicate that on the ground attempts to come up with solutions to providing services to farmers are resulting in innovative contracting approaches and combined public and private institutional arrangements. Contracting in and public–private coalition approaches, in contrast to purely public sector extension (characterized by ineffectiveness and inefficiencies) and purely private for profit extension (which may ignore public goods and concerns), may help achieve extension services which are both demand led and which internalize public concerns such as environmental protection, food security and socio‐economic equity. These coalition approaches can be improved and facilitated. They deserve greater analysis and may contribute to a better understanding of extension contracting and the roles of private and public organizations. Copyright © 2000 John Wiley & Sons, Ltd.     

Third molar development according to chronological age in populations from Spanish and Magrebian origin

Spain is frequently the entrance country into the European Union for undocumented immigrants, especially those from the Magreb (Northern Africa). Forensic age estimates for these persons are difficult because systematic studies of dental maturity are lacking. Three different populations were analyzed to determine the pattern of development of third molars as a tool for age estimation in people of different ethnic and geographic origin. Orthopantomograms from two different populations of Spanish origin (Galicia in northwestern continental Spain, and Ceuta, a Spanish province in Northern Africa) were compared to radiographs of molars from a Magrebian population (Northern Africa) resident in Ceuta. Orthopantomograms were obtained from a private dental clinic (n=344) in Galicia and from the Public Oral Health Services (n=228) in Ceuta. We looked for differences in third molar mineralization (determined with the Demirjian scale) that might serve as age indicators (older versus younger than 18 years). Differences in maturation patterns were found between sexes and populations of origin. Mineralization of tooth 38 was more advanced in males than females among subjects 18 years of age and older in all three populations. Moreover, mineralization of tooth 38 in subjects aged 18 years and older was significantly slower in the Spanish-Galicia population than in the Magrebian-Ceuta population. We found no significant differences between Magrebian and Spanish individuals from Ceuta. We conclude that differences in tooth 38 mineralization may be related more with socio-geographical than ethnic origin (ancestry), and thus constitute evidence of the relevance of socio-geographic rather than genetic factors in third molar development. We used ROC analysis to determine the accuracy of the examiner's ability to correctly estimate age as younger or older than 18 years. The results suggest that Demirjian stage for tooth 38 can be considered a good indicator of age in all three populations.
