A análise dos efeitos foi dividida em três etapas: (i) avaliação do efeito médio da aquisição, (ii) avaliação do efeito dinâmico e (iii) avaliação por rede adquirente. No que concerne aos efeitos médios, a aquisição está associada a um efeito positivo sobre o Conceito Preliminar de Curso (CPC), sobre o percentual de professores doutores (Doutores) e sobre o percentual de professores com regime de dedicação parcial ou integral (Regime). Considerando-se o efeito dinâmico da aquisição, os resultados sugerem efeito positivo sobre o CPC no segundo ano após a aquisição, efeito positivo sobre Doutores dois primeiros anos após a aquisição e efeito positivo sobre matrículas e ingressantes, passados pelo menos dois anos da aquisição. Além disso, a rede adquirente é relevante para avaliação dos efeitos da aquisição, de modo que os resultados podem ser distintos a depender de quem compra a IES. Os impactos encontrados são válidos utilizando diferentes especificações de modelos. Esses resultados indicam que a análise de fusões deve observar possíveis efeitos sobre a qualidade, um assunto ainda incipiente na literatura. / This work evaluates the impact of mergers and acquisitions on the quality and on the total enrollment and entrant students on undergraduate courses offered by Higher Education Institutions (HEI) acquired by educational business chains. The analysis of the effects was splitted into three parts: (i) assessment of the average effect of the acquisition, (ii) evaluation of its dynamic effect, and (iii) assessment by acquiring chain. Regarding the first one, acquisition accounts for a positive effect on the Preliminary Course Concept (PCC), on the percentage of PhD teachers and also on the percentage of teachers with partial or full time dedication. As to the dynamic effect of the acquisition, the results indicate a positive effect on the (PCC) in the second year after the acquisition, a positive effect on the percentage of PhD teachers in the first two years after the acquisition and a positive effect on enrollment and entrant students after two years of the acquisition. Moreover, the analysis indicates that the acquiring chain is relevant for assessing the effect of the acquisition, that is, the results may be different depending on who buys the HEI. The impacts that were found are valid employing different model specifications. These results indicate that the analysis of mergers should evaluate possible effects of acquisitions on the quality, which is an incipient topic in economic literature.

By flavin's unique structure, nature predestined riboflavin and its derivatives to the participation in redox processes within the bodies of all the living organisms. These biomolecules draw attention with intriguing optical properties and photosensitising abilities. Nature-inspired flavin derivatives share these qualities, and there is also a possibility of fine-tuning for the particular application from the chemical point of view. The thesis deals with two main aims. The first aim handles the synthesis of the trimer heteroaromatic precursor and 1,2-diketone. These key intermediates are essential for the future synthesis of the central aromatic core of the novel NH-free non-fused flavin derivative. The thesis introduces and verifies three approaches, including oxidation of diarylalkynes, nucleophilic addition of a corresponding organolithium compound to a Weinreb amide and benzoin condensation. The second aim covers the properties customization of NH-free fused systems by implementation of linear and bulky alkyl side-chains on the nitrogen atoms N1 and N3 of the alloxazine dilactam. N,N-alkylation introduced an increase in solubility in common organic solvents dichloromethane and chloroform. For the derivatives with 2-(adamantan-1-yl)ethyl substituents, high thermal stability was observed via TGA.
