A large-scale study of the relationship between blood and breath alcohol concentrations in New Zealand drinking drivers

Blood alcohol concentrations (BAC) and corresponding breath alcohol concentrations (BrAC) were determined for 21,582 drivers apprehended by New Zealand police. BAC was measured using headspace gas chromatography, and BrAC was determined with Intoxilyzer 5000 or Seres Ethylometre infrared analysers. The delay (DEL) between breath testing and blood sampling ranged from 0.03 to 5.4 h. BAC/BrAC ratios were calculated before and after BAC values were corrected for DEL using 19 mg/dL/h as an estimate of the blood alcohol clearance rate. Calculations were performed for single and duplicate breath samples obtained using the Intoxilyzer (groups I-1 and I-2) and Seres devices (groups S-1 and S-2). Before correction for DEL, BAC/BrAC ratios for groups I-1, I-2, S-1, and S-2 were (mean+/-SD) 2320+/-260, 2180+/-242, 2330+/-276, and 2250+/-259, respectively. After BAC values were adjusted for DEL, BAC/BrAC ratios for these groups were (mean+/-SD) 2510+/-256, 2370+/-240, 2520+/-280, and 2440+/-260, respectively. Our results indicate that in New Zealand the mean BAC/BrAC ratio is 19-26% higher than the ratio of the respective legal limits (2000).     

Democratic Regimes, Internal Security Policy and the Threat of Terrorism

Since terrorism poses a serious threat to the processes of liberal democracy governments should act decisively to curb terrorist groups. This article examines the range of political, judicial and enforcement measures available, assesses the problems associated with them and the conditions for their success. Political measures include reforms in response to popular unrest, negotiations with terrorist groups and amnesties to encourage an end to violence. Since terrorists seek to influence domestic and international public opinion, the authorities need to counter that propaganda and in particular to explain and justify the political, judicial and enforcement measures they adopt. Governments have to choose between treating terrorism like other forms of criminal behaviour or setting up special courts and passing emergency legislation, with the attendant dangers to civil liberties. Enforcement of anti-terrorist measures has quite often been inept. Coordination is required to prevent police anti-terrorist units and other security agencies from engaging in institutional rivalry. But if these agencies are efficient in their intelligence gathering, and politically supervised to ensure that they act within the law, they can be decisive in the reduction of terrorism, as in Western Europe at the end of the 1970s.     

Monarchy, Monopoly and Mercantilism: Brazil Versus the United States in the 1800s

GDP was $738 per capita in Brazil and $807 in the United States in 1800, but was $4,854 in the latter in 1900 and actually fell from $738 inBrazil by 1913. Relative factor endowments and institutions, broadlyconsidered, are twin traditional explanations for the extremely diversegrowth rates. In this paper we offer a complementary analysis of specificpolitical and economic structures to help explain the success andpersistence of monopoly restrictions in Brazil and the failure of internalmercantilism in the U.S. We conclude that Brazilian institutions provideda ripe and efficient environment for rent seeking. Such conditions did notexist in the U.S., a fact that helped produce the vast difference ingrowth in the 1800s.     

A review of security and privacy concerns in digital intelligence collection

In recent years, government leaks have brought many alleged potential privacy violating intelligence collection programs to the public arena. Intelligence collection can affect the privacy rights of citizens from any country. While the concept of privacy is a complicated one, United States citizen privacy is protected by various policies and laws. This paper reviews these alleged intelligence collection programs, as well as specific laws set in place to protect privacy. Also presented are discussions on public opinion and whether or not digital intelligence collection are providing a safer environment for Americans.     

Andalusia at the crossroads of Europeanness: immigration as a performance of coloniality

ABSTRACT

The semantics of cultural diversity, based on the political discourses of immigration as they appear in integration and anti-racist policies in Andalusia, underline the sense of Otherness of immigrant groups. In this article, Castaño, Martínez and Periáñez focus on the most relevant texts in the Planes Integrales para la Inmigración en Andalucía (Comprehensive Plans for Immigration in Andalusia). To date, these texts have formed the most significant discursive framework for representations of the third sector, trade unions and public agencies involved in the management of diversity. The key ideas in the plans revolve around transnational political references in the context of the European Union (EU). They impose a sense of Europeanness on Andalusia that is in opposition to its historical heritage, endogenous diversity and cultural specificity, and thus steer the imaginary of Andalusia's identity towards a Eurocentric idea that enhances the region's peripheral position. Immigration is regarded in the hegemonic media discourse and the social imaginary as a risk and a social problem. Integration policies, despite being couched in anti-racist rhetoric, are specifically targeted at immigrants, further enhancing the idea of Otherness. The notion of interculturality is the leitmotiv of these policies. In practical terms, however, action is limited to empty measures in the field of education. These policies, in sum, neutralize, rather than reinforce, the sense of equality on which interculturality is based. The examination of the intertextuality of Andalusian, Spanish and European discourses reveals the conformity of the discourse of Andalusia's coloniality within the framework of the EU.

After some brief background information on the reasons for its implementation, the methods used to choose the partner are discussed, as well as the technology transfer, with particular emphasis on R&D transfer. Finally, the plant's current stage of development is studied and its main characteristics are presented, as an example of a successful joint venture between culturally different and geographically distant countries.     

Evaluation of the Simultaneous Analysis of Organic and Inorganic Gunshot Residues Within a Large Population Data Set Using Electrochemical Sensors*,†

The increasing demand for rapid methods to identify both inorganic and organic gunshot residues (IGSR and OGSR) makes electrochemical methods, an attractive screening tool to modernize current practice. Our research group has previously demonstrated that electrochemical screening of GSR samples delivers a simple, inexpensive, and sensitive analytical solution that is capable of detecting IGSR and OGSR in less than 10 min per sample. In this study, we expand our previous work by increasing the number of GSR markers and applying machine learning classifiers to the interpretation of a larger population data set. Utilizing bare screen-printed carbon electrodes, the detection and resolution of seven markers (IGSR; lead, antimony, and copper, and OGSR; nitroglycerin, 2,4-dinitrotoluene, diphenylamine, and ethyl centralite) was achieved with limits of detection (LODs) below 1 µg/mL. A large population data set was obtained from 395 authentic shooter samples and 350 background samples. Various statistical methods and machine learning algorithms, including critical thresholds (CT), naïve Bayes (NB), logistic regression (LR), and neural networks (NN), were utilized to calculate the performance and error rates. Neural networks proved to be the best predictor when assessing the dichotomous question of detection of GSR on the hands of shooter versus nonshooter groups. Accuracies for the studied population were 81.8 % (CT), 88.1% (NB), 94.7% (LR), and 95.4% (NN), respectively. The ability to detect both IGSR and OGSR simultaneously provides a selective testing platform for gunshot residues that can provide a powerful field-testing technique and assist with decisions in case management.     

Reporting a fatality during tumescent liposuction

Deaths of patients during elective surgery have drawn attention to the danger of anesthesia. Tumescent local anesthesia is subcutaneous infiltration of large volumes of dilute lidocaine with epinephrine to produce vasoconstriction while delivering anesthesia over large areas without lidocaine toxicity. This report documents the case of a 38-year-old woman who attended an outpatient clinic to undergo liposuction of the abdomen and bilateral hips and thighs. According to one witness, around 30 min after anesthesia administration, the victim suffered an episode of tonic–clonic convulsion. When the emergency medical services arrived the patient was in asystole. She died in spite of attempted cardiopulmonary resuscitation. The patient had no significant past medical history including no history of allergies or any known complications with anesthesia. A complete autopsy was performed and possible causes of death such as myocardial infarction, aspiration of food or foreign body, and pulmonary embolism were discarded. Anaphylactic shock was considered a possible but unlikely explanation for the fatality. Toxicological analyses revealed the presence of lidocaine and mepivacaine in heart blood, at concentrations of 4.9 and 16.2 mg/L, respectively. All drugs involved in the case were detected using gas chromatography with nitrogen–phosphorus detector and confirmed using gas chromatography–mass spectrometry full scan mode after solid-phase extraction using Chem-Elut columns. An additional high-performance liquid chromatography coupled to diode-array detection screening also obtained the same results. Based on the autopsy findings, case history, and toxicology results, the forensic pathologists ruled that the cause of death was an overdose of local anesthetic agents. The Court of Law ruled the death as an involuntary homicide due to gross negligence.
