The effect of mass legalization on US state-level institutions: Evidence from the immigration reform and control act

Cocaine-related deaths: an enigma still under investigation

In recent years there has been an increase interest in cocaine-related death reflecting the rising trend in cocaine use in Europe. Nevertheless it is still now very difficult to attribute a death to cocaine. We can affirm that cocaine can be responsible for the cause of death only when there is a reasonably complete understanding of the circumstances or facts surrounding the death. Isolated blood cocaine levels are not enough to assess lethality, and should be always considered and evaluated in relation to concentrations of cocaine and benzoylecgonine concentrations in body tissue compartments, especially in brain and blood. We have reanalyzed all of our cocaine-related cases from 1990 to 2005, applying the methodology used by Spielher and Reed over 30 years ago. Our aim was to try to validate this model and verify its applicability and effectiveness after 20 years.     

Cross-cultural conflicts within sports teams

Since sports are increasingly used a way to bring formerly conflicting parties together post-conflict, more work needs to be done to ensure that sports are actually conducted in a way that promotes peace rather than exacerbates the conflict. Since many sports-for-peace programs cross cultural boundaries, this exploratory study was conducted to gain insights into interpersonal and cross-cultural conflicts within sports teams. This research was accomplished with three very culturally diverse teams of college-level athletes in a public university in the United States and focused on the types of conflicts, where those conflicts occurred, how the conflicts developed, who was involved, how the conflicts ended, and their effects on team cohesion. The findings of the study give valuable insight into how cultural differences and their resultant ramifications were viewed and worked through by the athletes involved. The authors also considered some ethical issues that resulted when groups of athletes were brought together from different cultures. This study is a first in a series of studies that examine the types of cross-cultural conflicts that occur within sports teams. The findings in this study are of interest to physical education instructors, coaches, peace education teachers, and professionals using sports to promote peace.     

All by Myself: Personal Qualifications versus Party Affiliation in Colombian Mayoral Elections

Political decentralization has been promoted as a way to devolve responsibility, bring government closer to citizens, and improve accountability. The shift prompted new local elections, but were the elected officials responsive to citizens or to national party elites? This study examines unique survey data from 125 Colombian mayors to identify the factors they believe were critical in their victories and thereby to identify the people to whom they believe they owe loyalty: citizens or party leaders. Examining the relative value mayors assign to their own actions versus those of the party, combined with information on how they financed campaigns, sheds important light on subnational electoral dynamics in Colombia.     

Comparison of bulk and compound-specific δ13C isotope ratio analyses for the discrimination between cannabis samples

Five marijuana samples were compared using bulk isotope analysis compound-specific isotope ratio analysis of the extracted cannabinoids. Owing to the age of our cannabis samples, four of the five samples were compared using the isotope ratios of cannabinol (CBN), a stable degradation product of Δ(9)-tetrahydrocannabinol (THC). Bulk δ(13)C isotope analysis discriminated between all five samples at the 95% confidence level. Compound-specific δ(13)C isotope analysis could not distinguish between one pair of the five samples at the 95% confidence level. All the measured cannabinoids showed significant depletion in (13)C relative to bulk isotope values; the isotope ratios for THC, CBN, and cannabidiol were on average 1.6‰, 1.7‰, and 2.2‰ more negative than the bulk values, respectively. A more detailed investigation needs to be conducted to assess the degree fractionation between the different cannabinoids, especially after aging.     

Y chromosome STR haplotypes in the Caribbean city of Cartagena (Colombia)

Haplotype data were obtained from a sample of 173 unrelated male individuals from Cartagena (Colombia), for 16 Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS460, DYS461, DYS635, GATA H4 and GATA A10). No shared haplotypes were observed, demonstrating the usefulness and informative power of these Y-STRs in male lineage identification in Cartagena. Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of Iberian origin.
