11	L'opposabilité des droits contractuels : étude de droit comparé français et libanais / The opposability of contractual rights : a comparative study of french and lebanese law El Rajab, Dima 19 December 2013 (has links) La notion d’opposabilité, dégagée par la doctrine française au début du siècle dernier, revêt aujourd’hui une importance cruciale relativement à la sécurité juridique. Ainsi, il est communément admis par la doctrine moderne qu’un tel concept explique les effets non obligatoires des contrats à l’égard du tiers, et notamment en matière de responsabilité. D’une part, le tiers est tenu d’un devoir d’abstention concernant tout acte qui pourrait porter atteinte aux contrats d’autrui. Le cas échéant, les contractants peuvent demander la réparation du dommage qu’ils subissent du fait de la convention conclue par le tiers au mépris de leurs droits. D’autre part, et parallèlement, le tiers victime est en droit d’engager la responsabilité délictuelle du cocontractant auteur de l’inexécution contractuelle lui ayant été préjudiciable. Pour autant, le nombre d’auteurs pour qui l’opposabilité ne peut pas réellement servir d’appui aux deux règles précitées ne cesse de s’accroître. La critique n’est pas cependant pleinement justifiée. En effet, l’étude approfondie de la signification exacte, du fondement et des caractéristiques déterminantes de l’opposabilité démontre que, moyennant une juste délimitation de son champ d’application, cette notion demeure utile, pour ne pas dire indispensable à la protection des contractants et des tiers. / The notion of opposability, which appeared in French doctrine at the beginning of the last century, is of crucial importance today in relation to legal certainty. Thus, it is generally accepted in contemporary doctrine that such a concept explains the non-obligatory effects of contracts towards third parties and particularly in regard to responsibility. On the one hand, third parties must abstain from any act which may harm others' contracts. If this should occur, parties to the contract could claim compensation for any damage suffered as the result of a convention under taken by a third party without regard to their rights. On the other hand, and in parallel, a third-party victim is entitled to make a tort claim against a cocontracting party failed to fulfill a contractual obligation when this would be prejudicial tohim. Having said that, there is an ever-increasing number of authors for whom opposability cannot be used to support the two preceding rules. However, this criticism is notcompletely justified. Indeed, an in-depth study of the exact meaning, of the basis and of the determining characteristics of opposability show that, given a fair definition of the boundaries, this notion remains useful, if not indispensable to protect parties to a contract and third parties.

12	Highway Development Decision-Making Under Uncertainty: Analysis, Critique and Advancement El-Khatib, Mayar January 2010 (has links) While decision-making under uncertainty is a major universal problem, its implications in the field of transportation systems are especially enormous; where the benefits of right decisions are tremendous, the consequences of wrong ones are potentially disastrous. In the realm of highway systems, decisions related to the highway configuration (number of lanes, right of way, etc.) need to incorporate both the traffic demand and land price uncertainties. In the literature, these uncertainties have generally been modeled using the Geometric Brownian Motion (GBM) process, which has been used extensively in modeling many other real life phenomena. But few scholars, including those who used the GBM in highway configuration decisions, have offered any rigorous justification for the use of this model. This thesis attempts to offer a detailed analysis of various aspects of transportation systems in relation to decision-making. It reveals some general insights as well as a new concept that extends the notion of opportunity cost to situations where wrong decisions could be made. Claiming deficiency of the GBM model, it also introduces a new formulation that utilizes a large and flexible parametric family of jump models (i.e., Lévy processes). To validate this claim, data related to traffic demand and land prices were collected and analyzed to reveal that their distributions, heavy-tailed and asymmetric, do not match well with the GBM model. As a remedy, this research used the Merton, Kou, and negative inverse Gaussian Lévy processes as possible alternatives. Though the results show indifference in relation to final decisions among the models, mathematically, they improve the precision of uncertainty models and the decision-making process. This furthers the quest for optimality in highway projects and beyond. highway development decision making under uncertainty real options jump processes infinitely divisible distributions Lévy processes measure theory characteristic function characteristic exponent Lévy jump measure probability measure cádlág stochastic process Wiener process Poisson process compound Poisson process finite activity models jump diffusion models Merton model Gaussian jump process Kou model double exponential jump process leptokurtic volatility smile infinite activity models pure jumps process generalized hyperbolic model modified Bessel function negative inverse Gaussian model geometric Brownian motion model log-normal distribution model normality assumption heavy-tailed distribution asymmetric distribution quantile-quantile plot Rydberg algorithm parameter calibration moments cummulants sum of squares Monte Carlo simulation least-squares regression backward dynamic programming discrete-time Markov chain land price traffic demand highway service quality index data collection traffic volume Annual Average Daily Traffic Ontario Ministry of Transportation Land Registry Office Freedom of Information Act seasonality value of transportation types of transportation systems importance of highway systems cost of wrong decisions monetary cost private sector cost human cost land expropriation environmental cost irreversibility cost factor time cost factor political cost factor opportunity cost opportunity cost of wrong decisions economic cost of wrong decisions economic cost of mis-estimation economic profit of wrong decisions cost of inaction price of making right decisions scope of decisions rehabilitation decision land acquisition decision expansion decision uncertainty modeling land acquisition cost expropriation cost construction cost material cost Montréal-Mirabel International Airport Pickering Airport 407 Express Toll Route Highway 407 Statistics
