O trabalho se propõe a, de acordo com os testes de credibilidade existentes, avaliar se a crise do México em 94 e a crise asiática, tendo como proxy os casos da Tailândia e Hong Kong poderiam ter sido previstas com os modelos existentes de credibilidade. Além disso, são feitas modificações nos testes de modo a tomá-los mais eficientes. Desta forma, pode-se comparar as conclusões a respeito baseadas apenas em modelos de previsão e conclusões construídas a partir da observação de outras variáveis econômicas. Os países analisados neste trabalho são Brasil, México (antes de 94), Venezuela, Rússia, Tailândia e Hong Kong.

Neste trabalho são abordados modelos de taxas de câmbio em regime de bandas e é discutida a aplicação de um desses modelos ao caso brasileiro. São descritos os modelos de taxas de câmbio em regime de bandas existentes na literatura no tocante a suas respectivas hipóteses, derivação matemática e propriedades teóricas derivadas. São também apresentados os resultados de testes empíricos, quando existentes, realizados para cada um desses modelos.

O trabalho pretende discutir o regime cambial brasileiro a partir da aplicação de um modelo econômico que considera um determinado comportamento das autoridades monetárias quanto a utilização da política monetária como mecanismo de controle cambial.

The focus of this dissertation is to understand the child and youth musical learning trajectory by using two philharmonic orchestras from Seridó, an area in the interior of Rio Grande do Norte. One is called the Hermann Gmeiner Philharmonic Orchestra of Aldeias Infantis SOS Project from Caicó, and the other is the 24 de Outubro Philharmonic Orchestra from Cruzeta. It emphasizes the singular relationship between the band s master and his students, based on a permanent interaction with tradition, creativity and change, resulting from a shared educational process. The idea that unites the work of these two communities is the gamble about the individual's formation as a complex human being, which it is not just concerned with the learning of a musical instrument, but is, more importantly, an educational process capable of facilitating the discovery of the self, others and society. The history and the course of the musical education of these two experiences were facilitated using a base of semi-structured interviews of the bands masters, students and people from two municipal districts. Their history is understood through analysis of the band s pictures and the theoretical-social approach is governed by the complexity idea expressed by Edgar Morin. For the author, complex means to `weave together`; therefore it is multidimensional, and it creates a dialogue about several domains and aspects that occur on the same phenomenon. The complex always supposes creativity and the relationship between the subject s reason and affectivity

Deformation bands are structures, developed in porous sandstones, that has small offsets and they are not shown on seismic section. The deformation bands of the pre and synrift sandstones of Araripe Basin were studied in outcrop, macroscopic and microscopic scales. The hierarchical, cinematic and spatial-geometric characteristics, and also the deformational mechanisms acting during its structural evolution were established too. In general, the mesoscopic scale observation allowed to discriminate deformation bands as singles or clusters in three main sets: NNE-SSW dextral; NE-SW normal (sometimes with strike-slip offset); and E-W sinistral; further a bed-parallel deformation bands as a local set. The microscopic characterization allowed to recognize the shearing and cataclastic character of such structures. Through the multi-scale study done in this work we verified that deformation bands analyzed were preferentially developed when sandstones under advanced stage of lithification. We also infer that the geometrical-spatial complexity of these bands, together with the presence of cataclastic matrix, can difficult the migration of fluids in reservoir rocks, resulting on their compartmentalization. Therefore, the study of deformation bands can aid researches about the structural evolution of sedimentary basin, as well as collaborate to understand the hydrodynamic behavior of reservoirs compartmented by these deformational structures

The authors present a case of constriction band syndrome in a 20-year-old male. There were constriction rings in the interphalangeal joints of hands and in the thigh, shortening of the lower limb and atrophic left gastrocnemius muscle. These findings belong to the described syndrome, which is uncommon and has no genetic implication. Personal antecedent: convulsive syndrome and corrective surgery for congenital bent foot.
