1. Combinação de classificadores para inferência dos rejeitados
Em problemas de credit scoring, o interesse é associar a um elemento solicitante de algum tipo de crédito, uma probabilidade de inadimplência. No entanto, os modelos tradicionais utilizam amostras viesadas, pois constam apenas de dados obtidos dos proponentes que conseguiram a aprovação de uma solicitação de crédito anterior. Com o intuito de reduzir

2. Controles por seleção e rejeição em discriminações condicionais em humanos e pombos / Select control and reject control in conditional discriminations in humans and pigeons
O estudo do responder controlado por relações de seleção ou rejeição insere-se no âmbito de investigações sobre as condições necessárias e suficientes para a formação de classes de estímulos equivalentes. O presente projeto pretendeu investigar aspectos relacionados ao tema em experimentos conduzidos com humanos e pombos. O primeiro experiment

3. HARE SOBRE A FALÁCIA NATURALISTA / HARE ON THE NATURALISTIC FALLACY
The aim of this dissertation is to present the criticism of Hare to ethical theories who commit the "naturalistic fallacy". These theories, according to the author, search for a "definition" of value words - words that underpin the majority of moral theories. Hare doubts the possibility of a definition of words like "good", "right, "fair", because he believe

4. Extensões da estatística scan espacial utilizando técnicas de otimização multi-objetivo
This work presents three new extensions of Kulldorffs Spatial Scan Statistic for the detection and inference of spatial clusters. Consider a map divided into m regions with known populations at risk and number of cases of some disease. We would like to know if the cases are randomly distributed over the m regions or not; if the cases are not randomly distrib

5. Strategies for the development of credit score with the inference rejected / Estratégias para o desenvolvimento de modelos de credit score com inferência de rejeitados.
Credit scoring models are usually built using only information of accepted applicants. This text considered strategies that can be used to develop credit score models with inclusion of the information of the rejects. We evaluated the techniques of reject inference: classification of rejected customers as bad, parceling, augmentation, use of market informatio

6. Molecular systematics and wing morphometric variation in species of the Drosophila tripunctata radiation / Sistematica molecular e variação morfometrica da asa de especies de Drosophila da radiação tripunctata
The tripunctata group is the second largest Neotropical group of Drosophila in number of species and was included in the tripunctata radiation which comprises other closely related groups. The second chromosome of Drosophila mediopunctata (a species that belongs to the tripunctata group) is highly polymorphic for inversions. Previous work suggested the pr

7. The importance of control considerations for heat exchanger network synthesis: a case study
Cost optimization in the synthesis decision tree often leads to a reduced degree of freedom which degrades the process’s ability to reject disturbances as a consequence of low controllability. In fact, Heat Exchanger Networks (HENs) obtained by traditional synthesis procedures that ignore controllability aspects must be evaluated in this context a posterio

8. Adoptive transfer of skin-selective autoimmunity induced by Skn alloantigenic disparities.
Two unlinked genes of the mouse, Skn-1 and Skn-2, each with alterative alleles, specify alternative cell-surface Skn alloantigens expressed only by epidermal and neural cells. C57BL/6 (B6) and A/J (A) strain mice differ at both Skn loci. Thus lethally irradiated B6 mice restored with (B6 x A)F1 hybrid hematopoietic cells [(B6 x A)/B6 chimeras] reject A strai
