Même si la régulation est associée à l’apparition de nouvelles formes de normativité, les actes administratifs unilatéraux occupent une place importante parmi ses différents outils. Envisagée comme une police spéciale visant la protection de l’ordre public économique, la régulation trouve dans les actes administratifs unilatéraux ses moyens d’exercice naturels. Il y a quatre types d’actes administratifs unilatéraux de régulation : les autorisations d’accès au marché, les actes réglementaires qui fixent les conditions d’exercice de la concurrence en son sein, les actes de règlement des différends et les décisions adoptées en matière de sanction. Au sein du système de régulation par voie d’actes administratifs unilatéraux se rencontrent plusieurs objectifs qui participent à la confection d’un régime inédit. L’étude du régime des actes administratifs unilatéraux de régulation confirme leur spécificité. Celle-ci se manifeste tout au long de leur cycle de vie. Adoptés par des autorités administratives indépendantes, ces actes peuvent être précédés d’une consultation publique, attribués après mise en concurrence des opérateurs ou cédés par leurs titulaires. Les évolutions que connaît leur régime les rapproche du droit souple, au point de rendre parfois difficile la distinction entre les deux instruments pour les opérateurs et le juge, au détriment de la sécurité juridique. Le juge administratif occupe une place centrale au sein du mécanisme de régulation. Confronté à un mécanisme normatif à deux vitesses et aux exigences que pose la régulation, il est amené à faire évoluer ses méthodes de contrôle et à construire progressivement son office de juge de la régulation. / Regardless of the fact that sectoral regulation is usually associated with the emergence of new forms of normativity, unilateral administrative acts have a prominent place among its various instruments. Conceived of as a special mission of the Administration whose main objective is the protection of public economic order, sectoral regulation is indeed normally exercised through unilateral administrative acts. There are four types of unilateral administrative acts that serve as instruments to sectoral regulation: decisions authorising access to the market, regulatory acts that set the conditions for competition in the market, dispute resolution decisions and decisions imposing sanctions. Regulating through unilateral administrative acts serves various objectives leading to a unique regime. Studying the latter confirms the specificity of these acts, a specificity that is evident throughout their life cycle. Adopted by independent administrative authorities, these acts can be submitted to public consultation, attributed to the operators on the basis of a competitive tender or transferred from one beneficiary to another. The evolution of their regime raises the question of their relationship with soft law: the distinction between the two instruments can at times be difficult both for the operators and the judge at the expense of legal security. The Administrative Judge plays a central role in the mecanism of sectoral regulation. Confronted with a two-geared normative mechanism and with the obligations that derive from sectoral regulation, his control methods are destined to evolve and his role as a regulatory judge is progressively refined.

This work deals with the problem to find and rate a solution how to administrate access rights in web based applications that are flexible and offer a fine-grained allocation of rights. In particular the program phpGACL is analyzed and integrated into an example application to prove the feasibility of this system in principle. / Diese Arbeit beschäftigt sich mit der Lösungsfindung und -bewertung des Problems, Zugriffsrechte webbasierter Anwendungen flexibel zu administrieren und eine möglichst feinkörnige Rechtevergabe zu erlauben. Insbesondere das Programm phpGACL wird analysiert und in eine Beispielanwendung integriert um die prinzipielle Realisierbarkeit des System zu überprüfen.

The study was undertaken to investigate the following: limiting factors faced by the developers in complying with the EIA conditions and to determine whether the various developers comply with the conditions. The study was undertaken by use of questionnaires, site visits, meetings, photographs, group interviews. Trained fields assistants were also used to administer the questionnaires in order to collect data. Data from two sites were collected between 2012 and 2014 and were intentionally collected in order to provide information regarding the implementation of mitigation measures. The collected data was subjected to SAS (statistical software). Chi-square test for independence was performed in order to compare the differences (Snedecor & Cocharen, 1978) between the two sites. Based on the results of the study, it is therefore recommended that competent authorities should consider drafting and supplying follow-up guidelines and these guidelines should also apply to all the relevant role players involved. / Environmental Sciences / M.
