Cocaine and homicide in Memphis and Shelby county: an epidemic of violence

In Memphis and the surrounding county, there were a record number of homicides (179) in 1986. During the same year, there was a marked increase in medical examiner cases where tests were positive for cocaine or its metabolites. Review of medical examiner and toxicology records from 1980 to 1986 found 87 cocaine related deaths; 46 of these were homicides. In 1986 alone, there were 53 cocaine related deaths, all manners, and 31 cocaine related homicides. In this year, 17.3% of the homicides were positive for cocaine or metabolite. The cocaine related homicides were similar to other homicides in terms of age, race, sex, blood ethanol concentration, and cause of death being due most often to firearms. In homicide cases in which an abuse drug was detected, cocaine accounted for the entire increase in 1986. Police records indicated that cocaine directly contributed to the homicide in 39% of the cases in which the drug was found. In other cases, we speculate that cocaine altered behavior may have contributed to the victim's being murdered either during the drug "high" or during the posteuphoric depression or withdrawal phase.     

The Impact of Mixed‐member Districts on Legislators' Behavior: The Case of Bolivia

Many studies suggest that mixed‐member electoral systems produce different attitudes and behaviors among representatives. This article assesses how this type of electoral system shapes Bolivian legislators' perceptions of their roles as representatives, their district activities, and their relationships with their political parties. It examines these dimensions using elite survey data and interviews with legislators and their personal assistants. The results show that the electoral system does not produce a uniform impact. It shapes how legislators perceive their role as representatives and the nature of the relationship they build with their political parties, but it does not produce differences in the kinds of activities that both types of legislators carry out in their districts.     

Social Trust, Social Capital and Perceptions of Immigration

Analyses of social capital and immigration have stressed the negative impact that culturally diverse societies have for the development of social trust. Ethnic heterogeneity, according to these studies, is associated with lower levels of social trust. However, social trust has not been studied as an independent variable in order to explain attitudes towards immigration. This article argues that societies with high levels of social capital facilitate the integration of immigrants because those members with high levels of social trust will tend to have more positive attitudes towards immigration. This hypothesis is empirically tested in a cross-country multi-level empirical analysis for sixteen European countries, drawing on the 2002–3 European Social Survey. This analysis shows that, regardless of the impact of other individual-level variables and contextual variables such as levels of unemployment or percentage of foreign population, those with high social capital do exhibit more positive attitudes towards immigration than the rest of the population.

Régimen político y democracia: conflicto constitucional en el pluralismo incompleto

Two constitutional features frame Mexico’s arrival to democracy: the creation of credible electoral institutions and the preservation of rules corresponding to the authoritarian regime inherited from the decade of the ‘30s in the twentieth century. These two sets of rules clash with each other, a fact which explains the low levels of democratic governance and the low quality of legislation and public policies. The political debate over this contradiction seems to have reached the lowest point and several different alternatives have been formulated to break the deadlock; nevertheless, the necessary political agreements that may clearly define a political path have not been reached. The article describes these processes and lays out the alternatives in dispute as well as possible outcomes in the near future.

Campaign finance reform and electoral competition: Comment

Campaign finance regulation is an important issue for democracies. Proponents of stricter contribution limits believe it will improve competitiveness. Opponents argue that contribution caps are just a mask for incumbency protection. This paper comments on John Lott’s 2006 article in “Campaign Finance Reform and Electoral Competition” in Public Choice.     

Validated method for the simultaneous determination of Δ-THC and Δ-THC-COOH in oral fluid, urine and whole blood using solid-phase extraction and liquid chromatography–mass spectrometry with electrospray ionization

A fully validated, sensitive and specific method for the extraction and quantification of Δ⁹-tetrahydrocannabinol (THC) and 11-nor-9-carboxy-Δ⁹-THC (THC-COOH) and for the detection of 11-hydroxy-Δ⁹-THC (11-OH THC) in oral fluid, urine and whole blood is presented. Solid-phase extraction and liquid chromatography–mass spectrometry (LC–MS) technique were used, with electrospray ionization. Three ions were monitored for THC and THC-COOH and two for 11-OH THC. The compounds were quantified by selected ion recording of m/z 315.31, 329.18 and 343.16 for THC, 11-OH THC and THC-COOH, respectively, and m/z 318.27 and 346.26 for the deuterated internal standards, THC-d₃ and THC-COOH-d₃, respectively. The method proved to be precise for THC and THC-COOH both in terms of intra-day and inter-day analysis, with intra-day coefficients of variation (CV) less than 6.3, 6.6 and 6.5% for THC in saliva, urine and blood, respectively, and 6.8 and 7.7% for THC-COOH in urine and blood, respectively. Day-to-day CVs were less than 3.5, 4.9 and 11.3% for THC in saliva, urine and blood, respectively, and 6.2 and 6.4% for THC-COOH in urine and blood, respectively. Limits of detection (LOD) were 2 ng/mL for THC in oral fluid and 0.5 ng/mL for THC and THC-COOH and 20 ng/mL for 11-OH THC, in urine and blood. Calibration curves showed a linear relationship for THC and THC-COOH in all samples (r² > 0.999) within the range investigated.The procedure presented here has high specificity, selectivity and sensitivity. It can be regarded as an alternative method to GC–MS for the confirmation of positive immunoassay test results, and can be used as a suitable analytical tool for the quantification of THC and THC-COOH in oral fluid, urine and/or blood samples.
