Contract between John Cronyn and Nelson Forsyth, December 16, 1854.

John Cronyn (1827-1898) emigrated to Canada from Ireland in 1837. He studied medicine at the University of Toronto, but was not granted his degree upon completion of the requirements. He refused to take the test oaths meant to exclude Catholics from the profession and was not granted his degree until several years later, when the discriminatory laws were rescinded. In 1850, he married Elizabeth Willoughby of Toronto. They settled in Fort Erie and he established a successful medical practice there. He was active in the community, serving as Superintendent of schools and one term as Reeve. In 1859 he relocated to Buffalo and continued to practice medicine there. Cronyn was instrumental in the establishment of a medical department at Niagara University, where he was a professor and president of faculty. Nelson Forsyth was the son of William Forsyth (1771-1841), a prominent businessman in Niagara who owned and operated the Pavilion Hotel (later known as Forsyth’s Inn). Nelson was also a businessman and lived in Fort Erie with his wife Archange Warren.

The law and economics of good faith in the civil law of contract

Good faith plays a central role in most legal systems, yet appears to be an intractable concept. This article proposes to analyse it economically as the absence of opportunism in circumstances which lend themselves to it. One of the objectives underlying the law of contract on an economic view is to curtail opportunism. In spelling out what this means, the paper proposes a three-step test: bad faith is present where a substantial informational or other asymmetry exists between the parties, which one of them turns into an undue advantage, considered against the gains both parties could normally expect to realise through the contract, and where loss to the disadvantaged party is so serious as to provoke recourse to expensive self-protection, which significantly raises transactions costs in the market. The three-step test is then used to analyse a set of recent decisions in international commercial transactions and three concepts derived from good faith: fraud, warranty for latent defects and lesion.

Wage Flexibility and Contract Structure in Germany

In this paper, we look at how labor market conditions at different points during the tenure of individuals with firms are correlated with current earnings. Using data on individuals from the German Socioeconomic Panel for the 1985-1994 period, we find that both the contemporaneous unemployment rate and prior values of the unemployment rate are significantly correlated with current earnings, contrary to results for the American labor market. Estimated elasticities vary between 9 and 15 percent for the elasticity of earnings with respect to current unemployment rates, and between 6 and 10 percent with respect to unemployment rates at the start of current firm tenure. Moreover, whereas local unemployment rates determine levels of earnings, national rates influence contemporaneous variations in earnings. We interpret this result as evidence that German unions do, in fact, bargain over wages and employment, but that models of individualistic contracts, such as the implicit contract model, may explain some of the observed wage drift and longer-term wage movements reasonably well. Furthermore, we explore the heterogeneity of contracts over a variety of worker and job characteristics. In particular, we find evidence that contracts differ across firm size and worker type. Workers of large firms are remarkably more insulated from the job market than workers for any other type of firm, indicating the importance of internal job markets.

Adhesion and transcellular migration of neutrophils and B lymphocytes on fibroblasts

During tissue inflammation, infiltrated leukocytes may have physical contacts with fibroblasts. We observed that neutrophils and B lymphocytes adhered in a larger proportion than T cells on cultured fibroblasts. Microscopy showed that adhesion was also characterized by leukocyte engulfment by the fibroblasts. In migration assays, only neutrophils and B lymphocytes were selectively able to migrate through a fibroblast barrier. Adhesion and migration were increased by stimulation with tumor necrosis factor-alpha (TNF-alpha) and phorbol-12-myristate-13-acetate (PMA). Antibodies against ICAM-1/beta2 integrin blocked the interaction of neutrophils to fibroblasts. For B lymphocytes the couple VCAM-1/alpha4 integrin was also involved in this interaction. Human skin fibroblasts presented similar adhesion characteristics as rat cardiac fibroblasts. By measuring the distance between the border of migration holes and cadherin-positive adherens junctions, more than 65% of the holes correspond to the transcellular route over the paracellular route. Furthermore, vimentin staining revealed that the migration holes were highly nested by intermediate filaments in accordance with the transcellular route. Our results demonstrated that engulfment of neutrophils and B lymphocytes by fibroblasts resulted in selective passage by a transcellular route.

Neutrality and the social contract

Given the fact of moral disagreement, theories of state neutrality which rely on moral premises will have limited application, in that they will fail to motivate anyone who rejects the moral premises on which they are based. By contrast, contractarian theories can be consistent with moral scepticism, and can therefore avoid this limitation. In this paper, I construct a contractarian model which I claim is sceptically consistent and includes a principle of state neutrality as a necessary condition. The principle of neutrality which I derive incorporates two conceptions of neutrality (consequential neutrality and justificatory neutrality) which have usually been thought of as distinct and incompatible. I argue that contractarianism gives us a unified account of these conceptions. Ultimately, the conclusion that neutrality can be derived without violating the constraint established by moral scepticism turns out to rely on an assumption of equal precontractual bargaining power. I do not attempt to defend this assumption here. If the assumption cannot be defended in a sceptically consistent fashion, then the argument for neutrality given here is claimed to be morally minimal, rather than fully consistent with moral scepticism.

Modulation de la réponse immunitaire dans le cerveau par la barrière hémato-encéphalique : implication en sclérose en plaques

La sclérose en plaques (SEP) est une maladie inflammatoire du système nerveux central (SNC) caractérisée par une infiltration périvasculaire de cellules mononucléaires, telles que les lymphocytes T CD4+ et CD8+, les lymphocytes B ainsi que les cellules myéloïdes qui comprend les monocytes, les macrophages et les cellules dendritiques (DCs). Ce phénomène d’infiltration est dû à une fragilisation de la barrière hémato-encéphalique (BHE). L’entrée des cellules immunitaires au SNC va mener à la destruction de la gaine de myéline et donc à l’apparition de plaques de démyélinisation. Ainsi, nous avons émis l’hypothèse que la migration des divers sous-types de cellules immunitaires du sang périphérique à travers la BHE est contrôlée par des mécanismes moléculaires distincts et spécifiques à chaque type cellulaire. Afin de répondre à cette hypothèse, quatre différentes études ont été mises sur pieds. En premier lieu, nous démontrons un effet bénéfique des statines sur la BHE en SEP, en diminuant la migration des lymphocytes T et des monocytes, et en diminuant la diffusion de marqueurs moléculaire soluble. Ce phénomène s’opère via la suppression du processus d’isoprenylation, et en empêchant probablement la contraction des cellules endothéliales de la BHE. De plus, nous démontrons que les monocytes qui migrent au SNC en condition inflammé sont en mesures de se différencier en DCs et d’induire une réponse inflammatoire de la part des lymphocytes T CD4+. La migration des monocytes à travers la BHE est contrôlée par une nouvelle molécule d’adhérence nommée Ninjurin-1. Le blocage de Ninjurin-1 conduit à une inhibition spécifique de la migration des monocytes in vitro, ainsi qu’à une amélioration des signes cliniques du modèle animal de la SEP, soit l’encéphalomyélite auto-immune expérimentale (EAE). Finalement, nous démontrons que la migration des lymphocytes T CD8+ au SNC s’effectue via l’intégrine alpha-4. De plus, la majorité des lymphocytes T CD8+ que l’on retrouve dans le liquide céphalo-rachidien de patients SEP, dans le SNC de souris EAE ainsi que dans le SNC de souris infectée au virus de l’hépatite murine portent un phénotype effecteur mémoire. Ces données pourraient expliquer l’émergence de leucoencéphalopathie multifocale progressive observée chez certains patients SEP traités au natalizumab, un anticorps dirigé contre l’intégrine alpha-4. En conclusion, notre étude a permis de démontrer l’importance des monocytes provenant de la périphérie dans le processus inflammatoire prenant part au SNC en SEP. L’inhibition d’entrée de ces cellules pourrait s’avérer bénéfique en SEP tout en permettant l’immuno-surveillance du cerveau, ce que l’anti-alpha-4 intégrine ne permet pas. Les statines pourraient s’avérer une autre option intéressante puisqu’elles agissent sur les processus inflammatoires impliqués dans la SEP.

Cabiakman et la suspension pour fins d’enquête en rapports collectifs

La suspension pour fins d’enquête est une mesure administrative qui permet à l’employeur de suspendre la prestation de travail d’un salarié le temps de faire enquête sur des actes qui lui sont reprochés et qui sont susceptibles d’entacher la réputation ou l’image de l’entreprise. Les principes applicables en la matière ont été précisés par la Cour suprême en 2004 dans l’arrêt Cabiakman c. Industrielle-Alliance, Compagnie d’assurance sur la vie, qui traite d’un contrat individuel de travail. Notre mémoire porte sur les circonstances justifiant une suspension pour fins d’enquête en rapports collectifs. Afin de vérifier le traitement de cette mesure administrative, nous avons effectué une analyse qualitative de la jurisprudence arbitrale québécoise en matière de suspension pour fins d’enquête avant et après Cabiakman. D’abord, nous avons vérifié la compatibilité des principes formulés dans Cabiakman et des principes issus de la jurisprudence arbitrale québécoise antérieure à cet arrêt. Ensuite, nous avons analysé l’influence de cet arrêt en rapports collectifs en examinant si la jurisprudence arbitrale québécoise qui lui est postérieure s'y réfère et en applique les principes. Finalement, nous avons tenté de corréler l’influence ou l’absence d’influence de Cabiakman sur la jurisprudence arbitrale à l’adhésion des arbitres à la thèse de la coexistence ou à la thèse de l’autonomie. Nos résultats ont démontré que Cabiakman n’est pas parfaitement compatible avec la jurisprudence arbitrale qui lui est antérieure puisque des principes différents de ceux énoncés par la Cour suprême s’y retrouvent. Aussi, nous avons remarqué que la jurisprudence arbitrale postérieure à cet arrêt s’y réfère souvent et en applique certains principes. Toutefois, nous ne considérons pas que l’influence de cet arrêt sur la jurisprudence arbitrale soit entièrement corrélée au rattachement des sentences arbitrales à l’une ou l’autre des deux thèses. En effet, d’autres hypothèses pourraient expliquer les résultats que nous avons obtenus.
