Cette thèse vise une meilleure compréhension des enjeux et rapports de force liés au plurilinguisme dans une institution publique. Son terrain d'investigation est constitué par l'Administration fédérale suisse, propice pour étudier les questions ayant trait à la représentativité linguistique, l'idéologie langagière, la politique linguistique et les pratiques linguistiques sur le lieu de travail. La théorie de la bureaucratie représentative constitue le point de départ de mon cadre théorique. Selon celle-ci, les administrations publiques devraient représenter tous les groupes sociaux de leur pays. Leur personnel devrait « refléter » la diversité de cette population pour des raisons d'égalité, de légitimité et de stabilité politique. Cependant, le critère linguistique est rarement étudié dans ce cadre. Afin de combler ce manque de théorie, je me suis tournée vers la théorie politique, la sociologie des organisations et la sociolinguistique critique. Mes données sont constituées de 49 entretiens semi-directifs menés dans deux offices fédéraux, ainsi que des textes officiels réglementant le plurilinguisme et la représentativité linguistique à l'Administration fédérale. J'ai ainsi confronté les conceptions des collaborateurs sur le plurilinguisme - exprimées dans les entretiens - avec celles de l'institution, reflétées dans sa politique linguistique. Mon analyse a démontré que, selon les acteurs ou le contexte, les enjeux liés au plurilinguisme se situent à des niveaux distincts : lorsque l'institution s'efforce de créer un lieu de travail affichant l'égalité des langues officielles, les collaborateurs perçoivent le plurilinguisme comme un élément parmi d'autres qui influence l'efficacité de leur travail. L'intérêt de cette recherche se situe tout aussi bien au niveau pratique que théorique: d'une part, mes observations définissent certaines «barrières» empêchant les pratiques linguistiques plurilingues et une représentativité linguistique proportionnelle à celle du pays. Elles contribuent ainsi à une réflexion concrète sur la manière de les surmonter. D'autre part, l'application au plurilinguisme, dans une institution publique, de concepts et modèles théoriques issus de disciplines variées permet d'ouvrir un regard neuf sur ceux-ci.

The evaluation of the competences acquired by the students in the context of a university education system is needed to enable professors to develop teaching-learning processes tailored to students" needs. The main goal of this paper is to analyze in depth the profile of the acquired competences of the bachelor students in Business Administration subjects. In that sense, this paper explains an experience in assessing bachelor student"s competences by applying an ICT-based digital platform designed for the selfassessment of personal and social competences. In particular, we apply an evaluation tool which was specifically designed for self-evaluating the project managers" generic and specific competences. The authors of this research have previous experience in implementing this evaluation tool in the subjects of Business Administration, Operations Management and Strategic Management taught in the Faculty of Economics and Business of the University of Barcelona. In this paper, the results show that there exist significant differences in the self-evaluation of competences depending on the respondent gender. This kind of tools benefits the three parties involved: students, university managers and organizations, and should be applied along the Bachelor as a transversal project and adapt the programs to achieve graduate students with higher levels of social and personal competences, as demanded by the labour market.

This articles describes three models which played a key role in the evolution of the International Olympic Committee (IOC) and all the organizations which contribute to the staging of the Olympic Games and constitute the Olympic System, from its beginnings in 1894 to the present day. This evolution and the addition of many stakeholders has increased the complexity of the management of the Olympic System over the years from pure Olympic administration (when the IOC headquarters moved to Lausanne in 1915) to Olympic network governance which must take into consideration more than 24 types of stakeholders, including goverments and intergovernmental organizations.

BACKGROUND AND PURPOSE Kyotorphin (KTP; L-Tyr-L-Arg), an endogenous neuropeptide, is potently analgesic when delivered directly to the central nervous system. Its weak analgesic effects after systemic administration have been explained by inability to cross the blood-brain barrier (BBB) and detract from the possible clinical use of KTP as an analgesic. In this study, we aimed to increase the lipophilicity of KTP by amidation and to evaluate the analgesic efficacy of a new KTP derivative (KTP-amide - KTP-NH 2). EXPERIMENTAL APPROACH We synthesized KTP-NH 2. This peptide was given systemically to assess its ability to cross the BBB. A wide range of pain models, including acute, sustained and chronic inflammatory and neuropathic pain, were used to characterize analgesic efficacies of KTP-NH 2. Binding to opioid receptors and toxicity were also measured. KEY RESULTS KTP-NH 2, unlike its precursor KTP, was lipophilic and highly analgesic following systemic administration in several acute and chronic pain models, without inducing toxic effects or affecting motor responses and blood pressure. Binding to opioid receptors was minimal. KTP-NH 2 inhibited nociceptive responses of spinal neurons. Its analgesic effects were prevented by intrathecal or i.p. administration of naloxone. CONCLUSIONS AND IMPLICATIONS Amidation allowed KTP to show good analgesic ability after systemic delivery in acute and chronic pain models. The indirect opioid-mediated actions of KTP-NH 2 may explain why this compound retained its analgesic effects although the usual side effects of opioids were absent, which is a desired feature in next-generation pain medications

Fibrinolytic therapy with Recombinant Tissue-Plasminogen Activator (rt-PA) is currently the only effective treatment for ischaemic stroke in its acute phase. Even though its use generally improves the prognosis of those patients likely to receive it, rt-PA administration is associated to several risks, such as haemorrhagic transformation ofthe ischaemic lesion and activation of excitotoxic mechanisms that may contribute to an increase in mortality or to a poor outcome in certain occasions, specially when arterial recanalization is not achieved or the rt-PA is lately administrated. Since in the last few years the role of glutamate in the neurotoxicity associated toischaemia has been widely studied and it is known that high plasma glutamate levels are predictors of ischaemic lesion growth and poor neurological outcome, it is necessary to find out which factors can contribute to glutamate release in the brain. The aim of this study is to determine if rt-PA administration is related to an increase in plasma glutamate levels, as well as to define if higher plasma glutamate levels at admission are related to different evolution and prognosis of our patients, both in those in which recanalisation is achieved and not. A series of cases of patients with hemispheric cerebral infarction admitted in our hospital during a year will be studied, and the data obtained from them will be compared to the data obtained from a control group, the samples of wich were takenyears ago, before rt-PA was routinely used
