Introduction of Mandatory Vehicle Inspection and Its Impact on Health: Case of Georgia

Abstract

To fight atmospheric air pollution, the Georgian government has implemented a law about vehicle inspection. The aim of this survey is to determine under which conditions are owners of technically faulty vehicles ready to give up using technically faulty cars. Within the qualitative study the in-depth interviews were conducted. Taxi drivers think that this law is harmful to them though they appreciate the efficacy of vehicle inspections. Controls should be placed on the quality of fuel as part of the development of public transport while increasing awareness about the harmful effects of atmospheric air pollution.     

ʽYou’re not getting rid of usʼ. Performing acts of citizenship in times of emigration

This article uses academic literature on acts of citizenship and performative citizenship to investigate the contestation, protest, and resistance actions carried out by the Marea Granate collective in defence of the citizenship rights of Spanish citizens living abroad. Marea Granate (Maroon Wave) is a transnational network of young Spanish emigrants that emerged in 2013 as a result of the recent widespread emigration provoked by the economic crisis and austerity politics in Spain. Based on their shared identity as economic exiles and demanding the right to participate in Spanish political life to change the conditions that led them to emigrate, the members of this organization have been carrying out innovative, creative citizenship acts that are breaking conventions and causing ruptures in the Spanish citizenship regime. These ‘transformative acts of recovering’, the term used to refer to Marea Granate’s demands and struggles for citizenship, have proven to be capable of being a driving force for change and also reveal the fluid and contested nature of citizenship in the contexts of austerity and emigration.     

Accuracy of 3D Scanners in Tooth Mark Analysis

The objective of this study was to compare the accuracy of contact and laser 3D scanners in tooth mark analysis. Ten dental casts were scanned with both 3D scanners. Seven linear measurements were made from the 3D images of dental casts and biting edges generated with DentalPrint© software (University of Granada, Granada, Spain). The uncertainty value for contact 3D scanning was 0.833 for the upper dental cast and 0.660 mm for the lower cast; similar uncertainty values were found for 3D-laser scanning. Slightly higher uncertainty values were obtained for the 3D biting edges generated. The uncertainty values for single measurements ranged from 0.1 to 0.3 mm with the exception of the intercanine distance, in which higher values were obtained. Knowledge of the error rate in the 3D scanning of dental casts and biting edges is especially relevant to be applied in practical forensic cases.     

Out of Sight,Out of Mind? External Voting and the Political Representation of Portuguese Emigrants

Over recent decades, emigrants have gained expanded voting rights on a global scale. Despite the normative debates about this issue, there are few empirical studies on why states decide to implement external voting and how electoral systems perform. This article seeks to fill this gap by looking at the Portuguese case. Our study suggests that a combination of political and socio-economic factors explains the implementation of external voting. On the other hand, the interests of political parties and the low level of civil society engagement are key to determining the failure of electoral reforms and the attempts to overcome the shortcomings of external voting.     

Confirmation by LC–MS of drugs in oral fluid obtained from roadside testing

The aim of this study was to assess the effectiveness of two current on-site oral fluid (OF) drug detection devices (OraLab and Dräger), as part of the Spanish participation in the Roadside Testing Assessment Project (ROSITA Project). The study was done in collaboration with the Spanish Traffic Police, in Galicia (NW Spain), during 2004 and 2005. A total of 468 drivers selected at the police controls agreed to participate through informed consent. In addition, saliva samples were collected and sent to the laboratory to confirm the on-site results. For this purpose, two different analytical liquid chromatography–mass spectrometry (LC–MS) methods were used to detect 11 drugs or metabolites in a 300 μL sample. Simultaneous analysis of morphine, 6-acetylmorphine, amphetamine, methamphetamine, MDA, MDMA, MDEA, MBDB, cocaine and benzoylecgonine was carried out using 100 μL of oral fluid, after an automated solid phase extraction. A different LC–MS method was performed to detect Δ⁹-THC in 200 μL of oral fluid using liquid–liquid extraction with hexane at pH 6. Both methods were fully validated, including linearity (1–250 ng/mL, 2–250 ng/mL) recovery (>50%), within-day and between-day precision (CV < 15%), accuracy (mean relative error < 15%), limit of detection (0.5 and 1 ng/mL), quantitation (1 and 2 ng/mL) and matrix effect. All of the positive cases and a random selection of 30% of the negatives were analyzed for confirmation analysis. Good results (sensitivity, specificity, accuracy, positive predictive value and negative predictive value > 90%) were obtained for cocaine and opiates by OraLab, and for cocaine by Dräger. However, the results for the other compounds could be improved for both detection devices. Differences in the ease of use and in the interpretation mode (visual or instrumental) were observed.     

The Impact of Affirmative Action on the Employment of Minorities and Women: A Longitudinal Analysis Using Three Decades of EEO‐1 Filings

What role has affirmative action played in the growth of minority and female employment in U.S. firms? This paper presents a longitudinal analysis of this question by exploiting rich variation across firms in the timing of federal contracting to identify affirmative action effects over the course of three decades spanning 1973 to 2003. It constitutes the first study to comprehensively document the long‐term and dynamic effects of affirmative action in federal contracting on employment composition within firms in the United States. I use a new panel of over 100,000 large private‐sector firms from the U.S. Equal Employment Opportunity Commission, including both firms that obtain federal contracts and are therefore mandated to implement affirmative action and firms that are noncontractors, across all industries and regions. The paper's key results indicate that the primary beneficiaries of affirmative action in federal contracting over 1973 to 2003 were black and Native American women and men. Dynamic event study analysis of workforce composition around the time of contracting reveals that a large part of the effect of affirmative action on increasing protected group shares occurred within the first four years of gaining a contract, and that these increased shares persisted even after a firm was no longer a federal contractor. The paper also uncovers important results on how the impact of affirmative action evolved over 1973 to 2003, in particular that the fastest growth in the employment shares of minorities and women at federal contractors relative to noncontracting firms occurred during the 1970s and early 1980s, decelerating substantially in ensuing years.     

A Novel Forensic Tool for the Characterization and Comparison of Printing Ink Evidence: Development and Evaluation of a Searchable Database Using Data Fusion of Spectrochemical Methods

A searchable printing ink database was designed and validated as a tool to improve the chemical information gathered from the analysis of ink evidence. The database contains 319 samples from printing sources that represent some of the global diversity in toner, inkjet, offset, and intaglio inks. Five analytical methods were used to generate data to populate the searchable database including FTIR, SEM‐EDS, LA‐ICP‐MS, DART‐MS, and Py‐GC‐MS. The search algorithm based on partial least‐squares discriminant analysis generates a similarity “score” used for the association between similar samples. The performance of a particular analytical method to associate similar inks was found to be dependent on the ink type with LA‐ICP‐MS performing best, followed by SEM‐EDS and DART‐MS methods, while FTIR and Py‐GC‐MS were less useful in association but were still useful for classification purposes. Data fusion of data collected from two complementary methods (i.e., LA‐ICP‐MS and DART‐MS) improves the classification and association of similar inks.     

Identifying background microbiomes in an evidence recovery laboratory: A preliminary study

16S rRNA profiling of bacterial communities may have forensic utility in the identification or association of individuals involved with criminal activities. Microbial profiling of evidence may, in the future, be performed within environments currently utilised for human DNA recovery, such as a forensic biology laboratory. It would be important to establish the background microbiome of such an environment to determine the potential presence of human or environmental microbial signatures to assist forensic scientists in the appropriate interpretation of target microbial communities. This study sampled various surfaces of an Evidence Recovery Laboratory (ERL) on three occasions including (a) before a monthly deep-clean, (b) immediately following the deep-clean, and (c) immediately after the laboratory’s use by a single participant for the purposes of routine item examinations. Microbial profiles were also generated for the involved participant and researcher for comparison purposes. Additionally, human nuclear DNA was profiled for each of the samples collected, using standard forensic profiling techniques, to provide a prospective link to the presence or absence of a background microbial signature within the ERL after its use. Taxonomic distributions across ERL samples revealed no consistent signature of any of the items sampled over time, however, major phyla noted within all ERL samples across the three timepoints were consistent with those found in human skin microbiomes. PCoA plots based on the Unweighted Unifrac metric revealed some clustering between participant microbial reference samples and surfaces of the ERL after use, suggesting that despite a lack of direct contact, and adherence to standard operating procedures (SOPs) suitable for human DNA recovery, microbiomes may be deposited into a forensic setting over time. The reference samples collected from the involved participant and researcher generated full STR profiles. Human DNA was observed to varying degrees in samples taken from the ERL across each of the sampling timepoints. There was no correlation observed between samples that contained or did not contain detectable quantities of human nuclear DNA and microbial profile outputs.
