Mental health in Canada: Are there any risky occupations and industries?

This study examined the role of occupations and industries in explaining differences among workers reporting poorer mental health in the Canadian workforce. It used data coming from a large representative sample of 77,377 workers engaged in 139 occupations and 95 industries. Logistic regression analysis was used to identify differences in the odds of reporting poorer mental health, adjusting for gender, age, education, marital status, and household income. Results identify ten occupations and nine industries at higher risk for workers reporting poorer mental health. The article concludes by highlighting implications for actors and policymakers and by specifying potential targets for intervention.     

University technology commercialization through new venture projects: an assessment of the French regional incubator program

This article assesses the performance of a technology business incubator program, established by the French government to support innovative new science and technology-based firms (NSTBF) that seek to commercialize laboratory research results. With a resource-based view and an institutional approach, this study predicts why some incubators may be more successful than others in supporting the development of NSTBF. An original longitudinal data set represents the results of a public incubator program, funded following the passage of a 1999 French law on innovation and research. The findings refer to a sample of 25 operationally active incubators and their 1200 graduated new ventures. This study contributes to the literature on business incubation by showing the importance of various incubator resource inputs for aiding NSTBF projects. It thus provides useful and timely feedback for researchers and policy makers.     

Why People are Committed to Human Rights and Still Tolerate Their Violation: A Contextual Analysis of the Principle–Application Gap

We report results from two experimental studies that show a large gap between support for general principles contained in the Universal Declaration of Human Rights and denunciation of concrete violations of these principles. Participants in both studies read different scenarios involving human rights violations committed by various authorities in Western contexts. In all situations, attributes or actions of the victims could be used to justify the violations. Participants indicated their level of support for each human right and the unacceptability of violations of it. A dual principle was found to organize positioning towards the violations: participants with a rights-based orientation denounced the violation independently of the victims attributes, whereas context-oriented respondents relied on the perceived deservingness of victims and considered the violation a just sanction of an unacceptable act. Judgmental differences were moderated by the situational context and participants extent of agreement with human rights.     

Comparison of ethanol concentrations in right cardiac blood, left cardiac blood and peripheral blood in a series of 30 cases

The aim of this study was to compare ethanol concentrations in right cardiac blood, left cardiac blood and peripheral blood. Samples were taken from a series of 30 medicolegal autopsies. Ethanol was measured by headspace GC-FID. In each case, the degree of putrefaction, chest or abdominal injury, and/or regurgitation of gastric contents into the airways were noted. Our results show that there exists in certain cases a marked increase in ethanol concentration in left cardiac blood compared with right cardiac blood and peripheral blood. In these cases, we observed (i) a high concentration of ethanol in the gastric contents and (ii) regurgitation of gastric contents into the airways. The authors discuss the post-mortem redistribution mechanisms which could explain these results and stress the value of sampling right cardiac blood at autopsy.     

The use of oral fluid and sweat wipes for the detection of drugs of abuse in drivers

Blood, urine, oral fluid (by spitting or with a Salivette), and sweat samples (by wiping the forehead with a fleece moistened with isopropanol) were obtained from 180 drivers who failed the field sobriety tests at police roadblocks. With quantitative GC-MS, the positive predictive value of oral fluid was 98, 92, and 90% for amphetamines, cocaine, and cannabis respectively. The prevalence of opiate positives was low. The proposed SAMHSA cut-off values for oral fluid testing at the workplace, proved their usefulness in this study. The positive predictive value of sweat wipe analysis with GC-MS was over 90% for cocaine and amphetamines and 80% for cannabis. The accuracy of Drugwipe was assessed by comparing the electronic read-out values obtained on-site after wiping the tongue and the forehead, with the corresponding GC-MS results in plasma, oral fluid, and sweat. The accuracy was always less than 90% except for the amphetamine-group in sweat.     

A contribution to the chemical profiling of 3,4-methylenedioxymethamphetamine (MDMA) tablets

A profiling method for the identification of impurities found in seized 3,4-methylenedioxymethamphetamine (MDMA) tablets is presented. Impurities of interest are extracted from an alkaline solution (pH 12.8) by diethyl ether and submitted to gas chromatography (GC)-mass spectrometry (MS) analyses. Identification of impurities is performed by electron impact ionization (Ei) mass spectrometry and confirmation by positive chemical ionization (Ci+) MS or, when possible, MS/MS (MS(2)). Repeat extractions of the same sample give an average relative standard deviation (R.S.D.) of less than 8% within the same day and 15% between days (results were obtained after normalization by the sum of peak areas, each one being acquired by selected ion monitoring (SIM)). Possible application toward batch comparison of samples is discussed. Chromatographic profiles are compared using the cosine function for evaluating similarity and/or dissimilarity among exhibits.

Constitutionalism and common knowledge: Assessment and application to a future European constitution

The purpose of the paper is to advocate that constitutions should be established through a contractarian process, rather than through conventions. To achieve it, they are studied from the perspective of the concept of common knowledge. We refer to its political philosophy and game theory dimensions. The making of common knowledge relates to communication and induction problems. The argument is applied to European constitutional integration, with a particular focus on administrative law.
