Requirements Engineering Technology Transfer: An Experience Report

This paper is an experience report on an initiative to incorporate requirements engineering practices into the development process of two large corporations. The project was framed by a government program to foster collaboration between academia, industry, and government agencies. Its expected result—proposals for cooperative work—is in itself a major challenge, since it was not decided from the beginning what aspect of requirements engineering would be covered by the proposals.We describe the cooperation process followed by the project partners, three universities, and two companies, the difficulties found therein, and compare our experience with other reports on the issue of adoption of requirements engineering into the mainstream practice.     

Population frequency distribution of HumF13A01, HumFXIIIB, and HumLIPOL loci in the Basque Country (Northern Spain)

A population study of unrelated individuals from the Basque Country (Northern Spain) was carried out using the GenePrint STR System. The PCR products were separated on denaturing polyacrylamide gels and visualized by silver staining. Three tetrameric loci were evaluated: HumF13A01, HumFXIIIB, and HumLIPOL. All loci fit Hardy-Weinberg expectations, and independence of alleles was found between these STR loci. A comparison with other population groups indicated allele frequencies are well conserved in Caucasians, but differ from other racial groups. The calculated parameters a priori probability of exclusion (Pex) and "power of discrimination" (PD) show how informative these loci are for the determination of identity and relatedness of individuals.     

Drugs in prehistory: chemical analysis of ancient human hair

Concern about drug abuse in modern populations has led to the development of specific methods for identification of cocaine, opiates and cannabis in human hair. Drug use in prehistory can provide indirect evidence of interpopulational contact and social stratification. This paper reports drug evaluation in nineteen ancient hair samples from archaeological sites in northern Chile. Each sample was tested for the presence of traces of cocaine, opiates and cannabis, in order to establish a standard methodology for studies of drug use among prehistoric groups. Although results are negative, this absence of evidence could be due to two main causes: (1) the individuals evaluated did not use any drugs, which does not mean that other members of their cultural group did, or (2) the wide range of known drugs studied did not consider some group specific drugs, derived from local or imported plants, thus meaning that a greater drug range must be tested. In any case, our study confirms that drug testing in prehistoric samples is viable. However, in order to determine what kind of substances were used in prehistoric times new patterns that incorporate all drugs which are not part of the western pharmacopeia must be created. Finally, a methodology for the study of drug use among prehistoric groups using ancient hair samples is described.     

What price mental health?

President Clinton aims to guarantee coverage not only to the severely disturbed but to all Americans. The cost, however, could be astronomical.     

A testable theory of problem solving courts: Avoiding past empirical and legal failures

Recent years have seen a proliferation of problem solving courts designed to rehabilitate certain classes of offenders and thereby resolve the underlying problems that led to their court involvement in the first place. Some commentators have reacted positively to these courts, considering them an extension of the philosophy and logic of Therapeutic Jurisprudence, but others show concern that the discourse surrounding these specialty courts has not examined their process or outcomes critically enough. This paper examines that criticism from historical and social scientific perspectives. The analysis culminates in a model that describes how offenders are likely to respond to the process as they engage in problem solving court programs and the ways in which those courts might impact subsequent offender conduct. This Therapeutic Jurisprudence model of problem solving courts draws heavily on social cognitive psychology and more specifically on theories of procedural justice, motivation, and anticipated emotion to offer an explanation of how offenders respond to these programs. We offer this model as a lens through which social scientists can begin to address the concern that there is not enough critical analysis of the process and outcome of these courts. Applying this model to specialty courts constitutes an important step in critically examining the contribution of problem solving courts.     

X-linked microsatellites in two Northern Spain populations

The X-chromosomal microsatellites HPRTB, DXS101, ARA, DXS7423, and DXS8377 were analysed by a pentaplex PCR in an expanded population sample from Cantabria and an independent sample of unrelated individuals from the Basque Country. Allele frequencies showed similar distributions, but minor variations were found for some loci.     

Jewish population genetic data in 20 polymorphic loci

Frequency data of 20 polymorphisms (13 autosomal and 6 Y-chromosome STRs and the Alu-insertion YAP) were determined in a sample of 124 unrelated Jewish individuals from Ashkenazi, Sephardic, North African and Oriental origin. The a priori statistical power of the set of studied loci was highly discriminating (PD=1 in 2.393 E+15 individuals for autosomal STRs, and a probability of finding two unrelated males with the same haplotype of less than 0.01). Some significant population differences were registered between Jews and other Circummediterranean populations in Y-chromosome loci frequencies.
