Between "uxor", "mater" and "concubina". Profile and identity of the Emperor Constantine in Late Roman legislation

We aspire to shape the Constantine’s personality in particular by analyzing his loving relationship, first with Minervina and then with Fausta, and not forgetting the bond with his mother Helena, hence the reference to uxor, mater and concubina in our title. We will analyze if these women exercised any influence on the composition of his production rules and, if so, to what extent they were able to determine the historical development of the following decades. From this point of view we must consider in general the emperor had to combine their political claims and government with these relationships, showing great skill in handling times and ways, always putting the first to the second.

Entre reglas y excepciones. Es decir, como legitimar las decisiones colectivas

El ensayo examina la cuestión de la aplicación de las reglas y de la capacidad real para tratar casos específicos, llegando a la conclusión de que es la excepción la que confirma la regla, a condición de que sea dialógicamente construida, para que sea interpretable y aplicable por parte de sus numerosos destinatarios en las políticas públicas más complejas y conflictuales, sobre todo a nivel local.

Les contrats et les droits fondamentaux : perspective franco-québécoise

Réalisé en cotutelle

Intégration d'une communauté minoritaire en période d'industrialisation : les Irlandais catholiques de la ville de Québec, 1852-1911

Au courant de la période industrielle, la ville de Québec a connu une croissance démographique rapide alimentée, entre autres, par une immigration européenne massive. Celle-ci contribua d’une façon notable aux changements socioéconomiques de la capitale durant cette période. Parmi les migrants, les Irlandais catholiques furent nombreux à transiter ou à s’établir à Québec et y laissèrent des traces encore visibles aujourd’hui. Or, bien que l’histoire de la diaspora irlandaise en sol nord-américain ait fait l’objet de plusieurs recherches, le cas de la ville de Québec, tout comme sa période d’industrialisation, reste encore peu étudié à ce jour. Grâce à l’utilisation des recensements nominatifs canadiens de 1852 à 1911 et des actes de mariage, cette étude a comme objectif d’analyser le niveau d’intégration de la communauté irlandaise de Québec sur les plans économique, social et spatial, et ce, à micro-échelle. Ainsi, en observant les emplois et la mobilité socioprofessionnelle des travailleurs, les unions exogames et l’évolution de l’établissement irlandais sur le territoire à l’étude, la présente recherche permet d’établir un constat positif : les Irlandais catholiques ont su s’intégrer à la société urbaine de Québec. Néanmoins, considérant la forte diminution démographique de la communauté au tournant du siècle, l’intégration s’est effectuée davantage à l’échelle des ménages que pour l’ensemble de la communauté.

Análise da eficiência de contratos de serviços de elevada especificidade terceirizados pela petrobras

The definition of the boundaries of the firms is subject that has occupied the organizational theorists long ago, being the seminal work of Coase (1937) indicated as the trigger for one theoretical evolution, with emphasis on governance structures, which led to a modern theory of incomplete contracts. The Transaction Cost Economics (TCE) and Agency Theory arise within this evolution, being widely used in studies related to the theme. Empirically, data envelopment analysis (DEA) has established itself as a suitable tool for analysis of efficiency. Although TCE argues that specific assets must be internalized, recent studies outside the mainstream of theory show that, often, firms may decide, for various reasons, hire them on the market. Researches on transaction costs face with the unavailability of information and methodological difficulties in measuring their critical variables. There`s still the need for further methodological deepening. The theoretical framework includes classic works of TCE and Agency Theory, but also more recent works, outside the mainstream of TCE, which warn about the existence of strategies in use of specific assets that aren`t necessarily aligned with the classical ideas of TCE. The Brazilian oil industry is the focus of this thesis, that aimed to evaluate the efficiency of contracts involving high specificity service outsourced by Petrobras. In order to this, we made the categorization of outsourced services in terms of specificity, as well the description of services with higher specificity. Then, we verified the existence of relationship between the specificity of services and a number of variables, being found divergent results than those that are preached by the mainstream of TCE. Then, we designed a DEA model to analyze the efficiency in the use of onshore drilling rigs, identified among the services of highest specificity. The next step was the application of the model to evaluate the performance of drilling rigs contracts. Finally, we verified the existence of relationship between the efficiency of contracts and a number of variables, being found, again, results not consistent with the theory mainstream. Regarding to analyze of efficiency of drilling rigs contracts, the model developed is compatible with what is found in academic productions in efficiency of drilling rigs. The results on efficiency show a wide range of scores, with efficiencies ranging from 31.79% to 100%, being low the sample efficiency average. There is consonance between the model results and the practices adopted by Petrobras. The results strengthen the DEA as an important tool in studies of efficiency with possibility to use for analysis other types of contracts. In terms of theoretical findings, the results reinforce the arguments that there are situations in which the strategies of the organizations, in terms of use of assets and services of high specificity, do not necessarily follow what is recommended by the mainstream of TCE
