De la rentabilité municipale des développements résidentiels

Sommaire: Dans cette analyse, la rentabilité fiscale de trente et un projets résidentiels construits au Québec entre 1971 et 1976 est calculée selon l'approche générale des analyses d'impact fiscal. Les particularités et limites méthodologiques des études d'impact municipal sont décrites et le modèle utilisé ici est présenté en détail. On peut utiliser les résultats à des fins de réquisitoire contre l'étalement urbain ou de plaidoyer en faveur de la densification du développement. Cependant, on ne devrait pas chercher à trouver dans ces résultats une condamnation globale de la maison unifamiliale, ni des arguments qui pourraient inciter les municipalités québécoises à abandonner leur fonction traditionnelle de maître d'oeuvre des infrastructures résidentielles. Abstract: The fiscal profitability of thirty-one residential developments which took place in Quebec between 1971 and 1976 is measured within the general framework of fiscal impact analysis. The characteristics and limitations of municipal fiscal impact studies are outlined and a specific model is described. The results could be interpreted as a strong argument against urban sprawl and in favour of more compact residential patterns. Nevertheless, these conclusions should not be overextended and construed as arguments against single family oriented projects or in favour of jettisoning the tradition of leaving to Quebec municipalities the responsibility of providing and financing urban services.     

Prevalence of psychoactive substances in truck drivers in the Nord-Pas-de-Calais region (France)

A previous study conducted in 1995 showed that psychoactive drug use by workers was higher in safety/security workstations than in the rest of the labour force. In order to verify this finding, we conducted a new study in 2003-2004 in the Nord-Pas-de-Calais region, restricted to truck drivers. The aim of this study was to allow harmonizing the professional practice of the occupational physicians, proposing drug prevention and drug testing policies, validating the analytical methods and the guidelines in case of positive testing results. One thousand truck drivers were studied. Urines were tested for amphetamines, cannabinoids, cocaine, opiates, benzodiazepines, buprenorphine and methadone by immunoassay. Urine ethanol determinations were performed by an ADH method. Positive urines for drugs of abuse, methadone or buprenorphine were then tested by gas chromatography or liquid chromatography coupled to mass spectrometry. Out of the 1000 drivers, cannabinoids were detected in 85 cases, opiates in 41 cases, amphetamines in 3 cases and cocaine in only one case. Buprenorphine was detected in 18 cases, methadone in 5 cases and benzodiazepines in 4 cases. Urine ethanol was positive in 50 cases. We found only one case with 6-monoacetylmorphine. Other positive opiates were metabolites of antitussives. The relatively low number of benzodiazepine positive urines could be explained by the lack of sensitivity of the test we used. All these results confirm those of the previous study for cannabinoids and ethanol in safety/security workstations. Positive results for methadone and buprenorphine are eight times higher than in the general population. In conclusion, the authors think that it will be of a great interest to test urine of truck drivers for other classes of psychoactive drugs, using a liquid chromatography-mass spectrometry method.     

Zu den verfahrensrechtlichen Implikationen der Kompetenzverteilung zwischen der EG und den Mitgliedstaaten im Bereich der Außenbeziehungen

Grundsätzlich finden in Bezug auf die Kompetenzverteilung zwischen EU und Mitgliedsstaaten für die Verhandlung völkerrechtlicher Verträge und den Erlass von „Durchführungsbestimmungen“ im Rahmen völkerrechtliche Vertragsreihe die allgemeinen Grundsätze der Kompetenzverteilung im Bereich der Außenbeziehungen Anwendung. Diese sind aber mit Blick auf die spezifische Problematik von Verhandlung und Durchführung völkerrechtliche Verträge einer Reihe von Präzisierungen zugänglich, die im Folgenden entwickelt werden. Diese Fragestellung ist allgemein im Recht der Außenbeziehungen von Bedeutung; im Umweltbereich ist sie aber wegen der Fülle völkerrechtlicher Verträge der Gemeinschaft und ihrem Charakter als i.d.R. gemischte Verträge besonders relevant. Astrid Epiney ist Professorin für Europarecht, Völkerrecht und Öffentliches Recht an der Universität Fribourg (CH) und geschäftsführende Direktorin des Instituts für Europarecht der Universitäten Bern, Neuenburg und Fribourg. Domènique Gross ist wissenschaftliche Mitarbeiterin des Instituts für Europarecht.* Der Beitrag wurde im Zusammenhang mit einem vom Schweizerischen Nationalfonds zur Förderung der wissenschaftlichen Forschung mitfinanzierten Projekt über die Kompetenzverteilung im Außenbereich zwischen EG und Mitgliedstaaten im Umweltbereich verfasst.     

Participation in Prison Activities: An Analysis of the Determinants of Participation

The positive associations of participation in prison activities (e.g. socio-cultural activities, educational courses, sports activities, vocational training, etc.), including reduction of recidivism, improvement of wellbeing and contributions to self-worth, are increasingly recognized. However, little is known about the characteristics by which participants differ from non-participants. In response to this research gap, this study aims to examine the determinants of inmate participation in prison activities. The determinants are categorized as outlined by the importation (individual characteristics) and deprivation (prison life characteristics) frameworks. Survey data derived from a research project in a remand prison in Belgium (N?=?486) provided the empirical evidence for the multiple linear regression analyses. The findings indicate that individual deprivation variables are more likely to predict participation. However, our findings also highlight that the combined effects of importation and deprivation characteristics are more powerful in explaining activity participation. The article concludes by discussing some paths for future prison research and implications for theory and practice. It provides impetus to organize and increase participation in prison activities, taking into account the diverse characteristics, needs and competences of the prison population.     

Postmortem Distribution of 3‐Beta‐Hydroxybutyrate

The concentrations of 3‐beta‐hydroxybutyrate (3HB) in femoral blood, urine, vitreous humor as well as pericardial and cerebrospinal fluids were retrospectively examined in a series of medico‐legal autopsies, which included cases of diabetic ketoacidosis, hypothermia fatalities without ethanol in blood, bodies presenting mild decompositional changes, and sudden deaths in chronic alcoholics. Similar increases in 3HB concentrations were observed in blood, vitreous, and pericardial fluid, irrespective of the cause of death, suggesting that pericardial fluid and vitreous can both be used as alternatives to blood for postmortem 3HB determination. Urine 3HB levels were higher than blood values in most cases. Cerebrospinal fluid 3HB levels were generally lower than concentrations in blood and proved to be diagnostic of underlying metabolic disturbances only when significant increases occurred.     

Acute Aortic Dissection Diagnosed after Embalming: Macroscopic and Microscopic Findings

A 58‐year‐old man died suddenly in Madagascar and poisoning was suspected. The body was embalmed after death and the general state of preservation was good. We found a major aortic dissection with a large false lumen from the aortic root to the common iliac arteries and a hemopericardium with formalinized blood clot. The intimal tear was on the ascending aorta, and an intramural hemorrhage was noted at the right coronary artery, attesting to a retrograde dissection. Microscopic studies confirmed aortic dissection with extensive intramural hemorrhage and also confirmed the retrograde dissection to the right coronary artery with a reduction of 90% of the true lumen. Classically, aortic dissection occurs in individuals with hypertension and individuals with genetic disorders of collagen formation. The diagnosis is often first established at the postmortem examination. Aortic dissection is therefore dealt with largely in necropsy studies. The usual cause of death is rupture into the pericardial sac. One case of bloodless dissection has been reported but the sudden death was explained by acute myocardial ischemia secondary to dissection of the left coronary artery. In our case, we found major hemopericardium and also intramural hemorrhage at the right coronary artery. We were able to make the diagnosis of aortic dissection and exclude the suspicion of homicide 15 days after death and after embalming.
