De nombreux constats contemporains s’alarment du malaise récurrent des ressources humaines hospitalières, particulièrement à l’endroit des médecins et des soignants, et par conséquent du risque de mauvaise qualité de prise en charge des patients. Adoptant une approche plus optimiste, des chercheurs américains en soins infirmiers ont mis en évidence depuis le début des années 1980 l’existence d’hôpitaux dits magnétiques, parce qu’attractifs et fidélisateurs, et où il ferait bon travailler et se faire soigner. Cette thèse vise à approfondir le concept de Magnet Hospital, à éclairer sa définition et sa portée pour la gestion des ressources humaines hospitalières en France. Suivant une démarche hypothético-déductive, la conceptualisation, fondée sur un état de l’art, débute par une appropriation du modèle synthétique du Magnet Hospital. Empruntant une perspective psychosociale, notre modèle original de recherche se focalise sur la perception, à l’échelle des unités de soins, des attributs managériaux du magnétisme hospitalier (leadership transformationnel, empowerment perçu de la participation et climat relationnel collégial entre médecins et soignants) et ses conséquences attitudinales positives (satisfaction, implication, intention de rester, équilibre émotionnel travail/hors travail et efficacité collective perçue). Une méthodologie quantitative interroge au moyen de 8 échelles ad hoc un échantillon représentatif de 133 médecins, 361 infirmières et 362 aides-soignantes de 36 services de médecine polyvalente français. Une série de modélisations par équations structurelles, selon l’algorithme Partial Least Squares, teste la nature et l’intensité des relations directes et indirectes du magnétisme managérial perçu. Les résultats statistiques indiquent une bonne qualité des construits et d’ajustement des modèles. Un contexte managérial magnétique produit son principal effet positif sur l’efficacité collective perçue. Des différences catégorielles existent quant à la perception de sa composition et à la transmission de ses effets par la médiation de l’efficacité collective perçue, signalant le caractère contingent du magnétisme. Ces résultats ouvrent des perspectives managériales et scientifiques, en soulignant l’intérêt des approches positives de l’organisation hospitalière. / Many contemporary findings are alarmed of the recurring discomfort of hospital human resources, especially against doctors and nurses, and consequently against risk of poor quality of care for patients. Adopting a more optimistic approach, American nursing scholars have highlighted since the 1980s, some magnet hospitals, able to attract and retain, and with good working and care conditions. This thesis aims to explore Magnet Hospital concept, to inform its definition and scope for hospital human resource management in France. According to a hypothetico-deductive approach, based on a review of the literature, the conceptualization begins with appropriation of synthetic Magnet Hospital model. Under a psychosocial perspective, our original research model focuses on perception of managerial magnetic attributes (transformational leadership, perceived empowerment of participation, collegial climate between doctors and nurses) and their consequences on positive job attitudes (satisfaction, commitment, intent to rest, emotional equilibrium work/family, perceived collective efficacy), at wards level. A quantitative methodology proceeds by a questionnaire of 8 ad hoc scales and interviews 133 doctors, 361 nurses, 362, auxiliary nurses, in 36 French medicine units. A set of structural equations modeling, according to Partial Least Squares, tests nature and intensity of direct and indirect relationships of perceived managerial magnetism. The statistical results show a good validity of constructs and a good fit of models. The major positive effect of magnetic managerial context is on perceived collective efficacy. Some professional differences exist about perceptions of composition and transmission of magnetic effects (via mediation of perceived collective efficacy), indicating the contingency of magnetism. These findings open managerial and scientific opportunities, emphasizing the interest for positive organizational approach of hospital.

In the contemporary context, in order to achieve superior performance, it reinforces the company's need to have, and make good use, of scarce, valuable, non-substitutable and inimitable resources. These resources include brands, customer base, knowledge, ability and competence of the work teams, corporate culture, partnerships and operational processes established, among other intangible assets, usually arising from a long and risky development process. Mergers and acquisitions (M & A) arise, then, as an important strategic action, being an alternative means to obtain and accelerate the accumulation of these resources within the companies. That is the subject of this work, which discusses the importance of existing and intangible assets disclosed, previous to the M & A transactions, their classification into various types, measurement, and impact on the resulting firm's financial performance in long term. The overall objective of this thesis was to analyze how this performance, after a minimum period of 36 months of the event, is related to the existence, level of disclosure and the nature of intangible assets in the organizations involved. One hundred-eighteen (118) companies were investigated in fifty-nine (59) cases of M & A occurred in France between 1997 and 2007; the study reflects a multi-method research, pluralistic, on qualitative and quantitative aspects. Intangible assets disclosure indicators were built by applying the content analysis technique to financial and accounting reports provided by the companies prior to the events, as well as financial indicators (proxies) for the existence of intangibles were calculated. These indicators were initially confronted with each other and later their explanatory power in relation to financial ratios of growth and profitability (for the corporation and its shareholders), which are the analyzed dimensions of financial performance. Many methods for statistical analysis were used in the multivariate data analysis (correlations and factor analysis, multiple regressions) and in the structural equation modeling (SEM), via Partial Least Squares (PLS). A total of twelve models, with statistics significance, were established to express the relationship among the constructs examined. Best results were achieved in the models developed with variables of semantic origin, in detriment of those with financial indicators only. The results obtained in this thesis leads to deduce that, in this study, there are positive relationships between the existence and the disclosure of intangible assets by firms involved in the operations of M & A and subsequent financial performance, measured by the corporate profitability and the growth of the resulting organization. This suggests that the strategic choice for business growth via M & A operations is favorable to the accumulation of intangible assets in the firms, in search for better results. / A alocação de recursos e a constante busca por diferenciais competitivos, visando melhores resultados, são grandes desafios empresariais. No contexto contemporâneo, para obter desempenho superior, reforça-se a necessidade de a empresa dispor, e fazer bom uso, de recursos raros, valiosos, não-substituíveis e de difícil imitação. Dentre estes recursos, destacam-se aspectos como as marcas, a base de clientes, o conhecimento, a capacidade e competência das equipes de trabalho, a cultura corporativa, as parcerias e os processos operacionais estabelecidos, dentre outros ativos intangíveis, geralmente decorrentes de longos e arriscados processos de desenvolvimento. As fusões e aquisições (F&A) surgem, então, como movimentos estratégicos importantes, sendo meio alternativo para obter e acelerar a acumulação destes recursos nas empresas. É essa a temática deste trabalho, que discorre sobre a importância dos ativos intangíveis existentes e divulgados previamente às operações de F&A de empresas, sobre a classificação dos seus diversos tipos, a sua mensuração e o seu impacto sobre o desempenho financeiro da firma resultante, no longo prazo. O objetivo geral desta tese foi analisar como este desempenho, após prazo mínimo de 36 meses do evento, está relacionado à existência, ao nível de divulgação e à natureza dos ativos intangíveis das organizações envolvidas. Foram investigadas 118 empresas, em 59 casos de F&A ocorridos na França entre 1997 e 2007, em uma pesquisa multi-métodos, pluralística, nas vertentes qualitativa e quantitativa. Foram construídos indicadores de divulgação (disclosure) de ativos intangíveis, mediante aplicação da técnica de análise de conteúdos aos relatórios contábil-financeiros disponibilizados pelas empresas antes do evento, e calculados indicadores financeiros (proxies) para a existência de intangíveis. Estes indicadores foram inicialmente confrontados entre si e posteriormente quanto ao seu poder explicativo em relação aos índices financeiros de crescimento e de lucratividade (empresarial e para os acionistas), que são as dimensões analisadas do desempenho financeiro. Utilizaram-se métodos de análise estatística de dados multivariados (análises de correlações, fatoriais, regressões múltiplas) e modelagem em equações estruturais, via Partial Least Squares (SEM- PLS). Foram estabelecidos, no total, doze modelos com significância estatística para expressar o relacionamento entre os construtos examinados. Alcançaram-se melhores resultados nos modelos desenvolvidos com variáveis de origem semântica, em detrimento daqueles que utilizaram indicadores exclusivamente financeiros. Os resultados obtidos nesta tese permitiram deduzir que há relações positivas entre a existência e a divulgação de ativos intangíveis pelas firmas envolvidas nas operações de F&A estudadas e o posterior desempenho financeiro, mensurado pela lucratividade empresarial e pelo crescimento, da organização resultante. Isto sugere que a opção estratégica por crescimento empresarial via operações de F&A é favorável ao acúmulo de recursos intangíveis nas firmas, na busca por melhores resultados.
