Differences in the Validity of Self-Reported Drug Use Across Five Factors: Gender,Race, Age,Type of Drug,and Offense Seriousness

This study expands our knowledge about the validity of self-reported drug use by examining how gender, race, age, type of drug, and offense seriousness interact to affect the validity of self-reported drug use. This study also provides a conceptual framework that can be used to examine the validity of self-reported drug use. Differences in the validity of self-reported drug use are explained by examining differences in underreporting and overreporting. Differences in underreporting and overreporting are then further examined while controlling for differences in base rates of drug use. As shown, whether one controls for base rates of use may drastically affect estimates of underreporting and overreporting. By using hierarchical loglinear, logit, and logistic regression models with the Drug Use Forecasting data, we show that Black offenders provide less accurate self-reports than White offenders. Black offenders do so because they are more likely to underreport crack/cocaine use than White offenders. This difference, however, disappears once differences in base rates are controlled. A Black offender who tests positive is not more likely to underreport crack/cocaine use than a White offender who tests positive. Black offenders are also more likely to overreport both marijuana and crack/cocaine use relative to White offenders. Contrary to the first, this difference is not attributable to a difference in base rates. Methodological and substantive implications of this distinction are discussed. No differences across gender, age, or offense seriousness were found.

Who is ready to climb the hill? The effect of legislative activity on promotion to higher offices in Chile

Previous research suggests that bill initiation is a mechanism used by legislators to foster personal votes. This article puts forward a theory whereby legislative activity is understood as a form of party service. Bill initiation records are used by parties to inform their decisions on who is ready to be promoted. The theory is evaluated using an original data-set from the Chilean Chamber of Deputies. Our empirical findings make a strong case for the hypothesis according to which parties reward those deputies who have shown to be effective legislators.     

Analysis of the Federal District’s Legislative Chamber in the Information Age

The study investigates the satisfaction with the work of the parliament of Brazilian Federal District. The survey was based on the competencies extracted from the institutional mission and targeted citizens who frequently use social networks. Inferential statistics were used to analyse the data. The results showed a great unsatisfaction about the institution. The most satisfied respondents are the less educated, while the most educated, older, and highest income respondents are the most unsatisfied. The results also highlighted the low interaction between respondents and the Chamber, the absence of an effective official communication channel, and actions associated with sustainable economic development will be more effective in increasing satisfaction.     

The Long Shadow of Police Racial Treatment: Racial Disparity in Criminal Justice Processing

This article explores racial disproportionality in criminal justice processing in an era of punitive criminal justice policies and mass incarceration. Using arrest data from New York State, the authors compare the racial disparity in prison sentencing with the disparity at arrest while controlling for crime type and criminal history of the arrest population. Findings show that the racial disparity in prison sentencing at the state level is established before courts begin criminal case proceedings. Scholars and policy makers interested in the sources of racial disparity in incarceration should concentrate on the processes that generate crime and arrests. However, a decrease in racial disparity at prison sentencing, relative to arrest, suggests that the practices of courtroom actors still merit scholarly attention.     

Support for emergency department screening for intimate partner violence depends on perceived risk

Emergency department (ED) screening for intimate partner violence (IPV) faces logistic difficulties and has uncertain efficacy. We surveyed 146 ED visitors and 108 ED care providers to compare their support for ED IPV screening in three hypothetical scenarios of varying IPV risk. Visitor support for screening was 5 times higher for the high-risk (86%) than for the low-risk (17%) scenario. Providers showed significantly more support for the need for ED IPV screening than visitors. Controlling for confounding by gender, race, experience with IPV, hospital, and marital status did not affect comparisons between groups. These responses indicate greater support for IPV screening in the ED for high-risk than for low-risk cases, particularly among visitors.     

La commission parlernentaire: mécanisrne d'imputabilitéà l‘égard des sous-ministres et des dirigeants d'organismes

Sommaire: Plusieurs parlementaires, divers analystes et deux commissions d'étude récentes, l'une au palier fédéral (Lambert) et l'autre au Québec (Bisaillon), ont traité de la possibilité d'implanter un régime d'imputabilité pour les administrateurs publics, particulièrement les sous-ministres et les dirigeants d'organismes. Les modifications apportées, au début de la présente année, aux règles de procédure de l'Assemblée nationale vont permettre une certaine expérimentation à cet égard. Une telle réforme améne l'auteur à examiner diverses contraintes qui pourraient influencer et même jouer contre son implantation, notamment: les principes de la responsabilité et de la solidarité ministérielles, l'évolution des rapports entre le gouvernement et l'administration, les différences de statut entre les sous-ministres et les dirigeants d'organismes et les précédents relatifs à la participation des sous-ministres et des dirigeants d'organismes aux travails de l'Assemblée. Ces contraintes sont assurément sérieuses car elles remettent en cause des éléments majeurs du système politique. Reste à savoir si, comme cela se produit souvent, les hommes politiques réussiront encore une fois à concilier ce qui paraît incompatible. Abstract: Several members of Parliament, various analysts and two recent commissions of inquiry, one federal (Lambert Commission) and the other from Quebec (Bisaillon), have studied the possibility of implementing an accountability system for public administrators, particularly deputy ministers and chief executive officers of agencies. Amendments brought forth earlier this year to the procedures of the National Assembly of Quebec will allow for experimentation in that area. Such a reform leads the author to examine various constraints in its implementation; in particular, the principles of ministerial responsibility and soolidarity; the evolution of relationships between government and administration; the status differences between deputy ministers and chief executive officers of agencies; the precedents concerning the participation of deputy ministers and chief executive officers in the work of the Assembly. Those constraints are of great importance since they challenge some major elements of the political system. It remains to be seen whether politicians will succeed once again in reconciling what appears to be incompatible.     

Distribution of Y chromosome lineages in Jerba island population

We have analysed Y chromosome polymorphism on six STR markers (DYS19, DYS389I, DYS390, DYS391, DYS392, and DYS393) and eight classical UEP markers (SRY10831a, YAP, SRY4064, M2, 92R7, M9, SRY2627 and 12f2) in three distinct ethnical, linguistic and cultural groups of Jerba island (Berbers, Arabs and a Jerban group of Sub-Saharan origin). Fst genetic distance and principal co-ordinate analysis based on STR haplotype frequencies, showed a genetic differentiation between the three Jerban groups and a genetic relationship between Jerban Berbers and Mozabites (a well defined Berber group in Algeria). Compound use of UEP and STR markers have increased discriminatory capacity. The detection of the most common haplotype (H9) in both Berbers and Mozabites may be useful in forensic special cases.     

Nuclear and mitochondrial DNA quantification of various forensic materials

Due to the different types and quality of forensic evidence materials, their DNA content can vary substantially, and particularly low quantities can impact the results in an identification analysis. In this study, the quantity of mitochondrial and nuclear DNA was determined in a variety of materials using a previously described real-time PCR method. DNA quantification in the roots and distal sections of plucked and shed head hairs revealed large variations in DNA content particularly between the root and the shaft of plucked hairs. Also large intra- and inter-individual variations were found among hairs. In addition, DNA content was estimated in samples collected from fingerprints and accessories. The quantification of DNA on various items also displayed large variations, with some materials containing large amounts of nuclear DNA while no detectable nuclear DNA and only limited amounts of mitochondrial DNA were seen in others. Using this sensitive real-time PCR quantification assay, a better understanding was obtained regarding DNA content and variation in commonly analysed forensic evidence materials and this may guide the forensic scientist as to the best molecular biology approach for analysing various forensic evidence materials.
