abstract: There has been much debate in the world of academia over the valuation of conglomerates. This thesis proposes the use of the EVA theory in explaining fluctuations in conglomerates’ valuation, and we believe that ROIC, WACC, and ROIC-WACC are three indicators that to a certain extent explain these valuation fluctuations. Through analysis of a sample containing 23 conglomerates, this thesis finds that ROIC, WACC, and ROIC-WACC exhibit positive correlation with valuation fluctuations. In the case study on Fosun, this thesis finds that ROIC-WACC is highly correlated with Fosun’s valuation fluctuations and next with ROIC. Thus this thesis conjectures that for investment companies for which investment capital is derived largely from insurance float, such as Fosun, ROIC-WACC is a better valuation tool. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2015

A análise é realizadas a partir dos relatórios contábeis e administrativos das holdings centrais dos grandes grupos econômicos e de bases de dados sobre estrutura acionária, indicadores financeiros e investimento externo direto. A interpretação baseia-se no conceito de capital financeiro, ao qual se propõem uma interpretação própria ao caso brasileiro. Neste sentido, a evolução dos grupos econômicos no Brasil é compreendida como um movimento de inserção internacional periférica do grande capital brasileiro, em um sistema capitalista no qual as transformações recentes reforçaram os aspectos de financeirização do sistema em seu conjunto. Apoiado no conceito de semiperiferia, o estudo realizado das transformações nos grupos econômicos brasileiros apresenta uma perspectiva sobre a evolução das formas concretas de consolidação de uma posição diferenciada em relação à periferia do sistema capitalista por parte da economia brasileira, através do suporte de mecanismos institucionais criados ao longo da industrialização / Abstract: The present work is an interpretation of the restructuring process of Brazilian big business in the most recent period. Through the analysis of 20 main Brazilian Economic Groups, their ownership structure and accounting indicators, the analysis aiming to describe the reorganization of the links between state-owned business, union pension funds and economic groups in Brazil since the privatization process in the nineties. The work proposes for that an interpretation of the concept of Financial Capital, which was put forth by Rudolph Hilferding. In this sense, the evolution of Brazilian main economic groups is understood as a specific path followed by some peripheral economic groups which increased their spaces of accumulation during the recently process of financialisation of the capitalist system. By using the concepts of Financial Capital and Semiperiphery, the analysis of transformation in Brazilian big business is presented as an attempt to improve the knowledge about how part of periphery of capitalist system was transformed and differentiated themselves from the rest. The interpretation proposes that the constitution of specific financial mechanisms during the industrialization process is a fundamental issue to understand different paths of financialisation in periphery of the capitalist system / Doutorado / Teoria Economica / Doutor em Ciências Econômicas

Liquid crystals are a vast and diverse class of materials which ranges from fluids made up of simple rods, polymers and solutions, to elastomers and biological organisms. Liquid crystal phases are neither crystalline, nor a ‘normal’ isotropic liquid, but lie somewhere in between these two common states of matter. Liquid crystals have found enormous use in display devices due to their electro-optic properties. In this thesis, the optical and electro-optical properties of some chiral liquid crystalline phases are studied. The optical and electro-optical behaviour of liquid crystalline blue phases has been investigated via a detailed analysis of the reflection spectrum from thin, vertical field (VF) cells. Spectral analysis in this thesis was performed using a numerical fitting technique based on the Berreman 4x4 matrix method. The validity of the technique was proved through comparisons of independent measurements with the calculated physical parameters. A novel Kerr effect measurement method was proposed in this thesis and a known material was used to verify this new method. The Kerr constant together with its dispersion relation was measured using a white light source. An unusually large Kerr constant, K, is determined in the blue phases of a non-polymer stabilized material, ~ 3x10-9 mV-2 (BPI). The large value of K is attributed to significant pre-transitional values of the dielectric anisotropy and birefringence. K follows an inverse dependence on temperature which is more marked in BPII than BPI, and we consequently suggest that the BPI demonstrates properties best suited to electro-optic devices. The field effects in blue phase include electrostriction and the influence of the Kerr effect was separated from electrostriction phenomena for the first time in this work. Finally in the Kerr effect measurements, the Kerr constant in the optically isotropic dark conglomerate phase of a bent-core material was studied for the first time, with rather low values, ~1x10-11 mV-2. The low Kerr constant can be understood in the context of the physical properties of the material. Supercooling phenomena in the blue phase were studied through an analysis of the optical properties in thin cells. Features including the Bragg reflection peak jump and hysteresis are measured through the reflection spectra. A blue phase sample with a single orientation over an area of millimeters was prepared to help the spectra study of the blue phases. Although some previous reports indicated that there may be a new blue phase in the supercooled region, we find that there is no evidence shows that the supercooled blue phase has a different structure from the BPI.Chiral molecules have been included as dopants in achiral bent-core materials to produce a range of new chiral mixtures. Different host materials and chiral dopants have been used to produce several chiral nematic materials in which the chiral nematic phase, the underlying smectic phase and the blue phases are examined. The order parameter is determined as a function of temperature in the chiral nematic phase, and compared to that determined for several calamitic materials; no discernible difference is found. A study of the pitch divergence in the chiral nematic phase of the bent-core mixtures shows interesting properties at both low temperature (as the smectic phase is approached) and at high temperatures (at the transition to the blue phase). An unusual phase separation of the chiral dopant in the mixtures is reported, and details are deduced through a comparison between different mixtures. It is found that a dopant with similar clearing point to the bent-core material has less likelihood of phase separation. Although the blue phase temperature range is extended in these mixtures in comparison with typical values for calamitic materials, it does not extend beyond 2K in any of the materials. Both blue phase I and the fog phases are observed in these chiral bent core systems, but no BPII is observed in any of the materials studied. The small k33 (~ 2.8 pN at 10 K below clearing point) in the bent-core host material is suggested as one of the reasons that the blue phase range is not enhanced as much as may have been expected from reports by other authors.

La presente tesis de investigación fue elaborada con la finalidad de contribuir con el estudio de la construcción de rampas de acceso a excavaciones mediante el análisis de los taludes provisionales sin sostenimiento que garanticen la estabilidad global en el Conglomerado de Lima. Las rampas de acceso son estructuras provisionales cuya construcción no se rige bajo normativas o indicaciones establecidas, además no contempla un estudio, se basa en la experiencia del responsable en obra. La ciudad de Lima se emplaza sobre un suelo gravoso el cual contribuye a que sea posible optimizar el grado de inclinación de los taludes provisionales. El alcance de este trabajo consiste en modelar una rampa de acceso en el conglomerado típico de Lima aplicando las sobrecargas existentes de la maquinaria y realizar un análisis de estabilidad global frente a condiciones estáticas y pseudodinámicas. Mediante la técnica de retroanálisis basándose en el método de Equilibrio Límite en Slide se estimarán los parámetros de resistencia mínimos característicos de la grava de Lima, el parámetro de cohesión y ángulo de fricción. A partir de ello se procederá a la optimización de los taludes, evaluando los diferentes grados de inclinación, y se estimarán las deformaciones producidas en los taludes a través del programa Plaxis, basado en Elementos Finitos. Finalmente se exponen las conclusiones obtenidas de la presente tesis de investigación, además de brindar recomendaciones para futuras investigaciones relacionadas a este tema. / This research thesis was developed with the purpose of contributing to the study of the construction of access ramps to building’s excavations by unsupported provisional slopes analysis to guarantee the global stability factor in the Lima Conglomerate. The access ramps are provisional structures whose construction is not governed by norms or established indications, in addition it does not include a study, it is based on the experience of the person responsible for the work. The city of Lima is located on a gravelly ground which helps to optimize the degree of inclination of the provisional slopes. The scope of this work is to model an access ramp in the typical conglomerate of Lima applying the existing machinery overloads and perform an analysis of global stability against static and pseudodynamic conditions. The minimum resistance parameters characteristic of the Lima gravel, the cohesion parameter and friction angle will be estimated using the retro-analysis technique based on the Limit Equilibrium method in Slide. From this, the slopes will be optimized, evaluating the different degrees of inclination, and the deformations produced in the slopes will be estimated through the Plaxis program, based on Finite Elements. Finally, the conclusions obtained from this research thesis are presented, as well as providing recommendations for future research related to this topic. / Tesis

More than 100 landslides have been mapped along the southeast flank of the Uinta Mountains. Large landslide deposits are up to 4.6 kilometers long and have an area of approximately 5-9 km². Landslide types include multiple and successive rock slumps, debris slumps and debris flows. Most landslides have a main head scarp in the Bishop Conglomerate and the large landslides have many minor scarps. Multiple slump blocks are manifest by repeated transverse ridges and trenches in the head area of some landslides. Most body and toe areas are deeply incised by gully erosion (up to 91 meters deep) and drainages are well developed with little ponding. Detailed mapping of the large landslides shows that the deposits are an accumulation of successive slope failures that have continually eroded the landscape over time. Many landslides in the area appear to be inactive and dormant but slopes may continue to fail particularly if landslides are disturbed. A Geographic Information System (GIS) was used to analyse slope failing factors and the main factor that seems to have contributed to slope failure is the presence of abundant shale-rich, weak bedrock capped with the thick and fairly resistant Bishop Conglomerate. Slopes are further destabilized as water percolates down through the porous Bishop Conglomerate. Eventually the water meets underlying shale-rich bedrock where it is channelled near this contact until it emerges as springs. This groundwater flow likely reduces shear strength of the shale-rich substrate and of some of the finer grained layers in the Bishop Conglomerate. Other important slope failure factors include the removal of easily erodable Mesozoic shales from beneath the more-resistant Bishop Conglomerate, headward gully erosion, bedrock dip and slope aspect.

Maps 1-4 are inserts within the thesis back cover / The Cambro-Ordovician sequence at St. Simon, Québec, was divided informally into ten horizons by Mathey (1970). The most prominent lithologies within the horizons are pelites, feldspathic sandstones and petromict conglomerates. One horizon 50 metres thick of feldspathic sandstones and conglomerates, described in this study, consists of three large fining upward sequences·. The fining upward sequences are defined by the occurrence of five facies. These facies are: poorly sorted coarse conglomerates, well sorted coarse conglomerates, medium conglomerates with scattered pebbles and boulders, fine conglomerate with scattered pebbles and boulders and coarse sandstones. The base of each sequence is characterized by the occurrence of coarse conglomerates; the top is characterized by the occurrence of fine conglomerates and coarse sandstones. Rarely do the coarse conglomerates grade into thick developments of medium and fine conglomerates. The fine conglomerates grade in places into coarse sandstones, although generally the coarse sandstones have sharp bases. The conglomerates display sharp bases, normal and inverse grading, grain imbrication and orientation. The long axes of the grains, which define the orientation are parallel to, and not transverse to the flow direction suggested by the imbrication. To produce these features it is suggested that turbulence and dispersive pressures were operative within the flow. If the pebbles had moved as bed load material, they would have come to rest with their long axes transverse and not parallel to the flow direction suggested by the imbrication. The term "fluxoturbidite" (Dzulynski et al., 1959) has been applied to some coarse grained deposits in geosynclinal sequences. The characteristic features of "fluxoturbidites" are their unusually coarse grain size, thick irregular bedding with associated slump structures and poorly developed grading. The differences between the conglomerates described in this study and the typical "fluxoturbidite" preclude the use of this term to describe the deposits described by the author. It is suggested that the conglomerates were deposited upon a submarine fan complex by currents which flowed parallel to the present tectonic axes. / Thesis / Master of Science (MSc)

<p> The Archean pyroclastic conglomerate studied has six clast types which can be condensed to four clast families based on lithology. The quartz clasts have an average strain of X:Y:Z=1.21:1:0.55 while the pumice clasts have an average strain of X:Y:Z=1.27:1:0.47. The difference is strain between these clast families can be attributed to their different viscosities. The quartz clasts have an assumed viscosity ratio between the clasts and the matrix of unity and are taken to represent the strain in the rock as a whole. The sulphide and black clasts have strain ratios much higher than the quartz because of recrystallization of the sulphide and cleavage formation effecting the black clasts.</p> <p> The sedimentary structure of the deposit and its position between mafic pillow basalts indicate that the deposit is a result of the deposition of a subaqueous pyroclastic debris flow in a proximal environment.</p> / Thesis / Bachelor of Science (BSc)

<p> The Archean "Loose Pebble Bay" conglomerate, Manitou Lake, northwestern Ontario, contains a variety of clast types, not all of which can be readily ascribed to local lithologies. This study was undertaken to determine the modal clast composition of the conglomerate, and investigate the origin of the clasts. The conglomerate lies near the top of a stratigraphic sequence which includes mafic and felsic volcanic rocks, iron formations, conglomerates, sandstones and argillites. The conglomerate unit itself consists of interbedded conglomerate and sandstone, and probably represents a channel-fill deposit of an ancient submarine fan.</p> <p> Modal percentages of clast types were obtained using a line-intercept method. They indicate that most of the debris in the conglomerate can be reasonably attributed to uplift and erosion of the lateral equivalents of the underlying stratigraphy, except for the granitoid clasts, which have no known origin within the area.</p> <p> Petrographic examinations of the clasts indicate that field identifications must be confirmed with thin section investigations.</p> <p> The modal composition of granitoid clasts was determined utilizing both thin sections and stained slabs. Most of the granitoid clasts are granodiorite, or lie just within the granite field, adjacent to the granodiorite field. Textural studies of the granitoid clasts suggest that gneissic and allotriomorphic-granular textured rocks may have formed by deformation or partial recrystallization along grain boundaries of previously hypidiomorphic-granular rocks. Textures generally indicate intrusive origin and slow cooling, although two granophyric samples may have solidified at relatively shallower depths than the other granitoid rocks.</p> <p> The textures and compositions of most of the granitoid clasts suggest that they were derived from one intrusive body. Intrusion of such a body into the volcanic-sedimentary belt, followed by uplift and erosion, would account for the presence in the "Loose Pebble Bay" conglomerate of granitic clasts and clasts similar to the underlying rocks. However, no evidence of such an intrusion has been found in the Manitou Lake area, and two of the granitoid clasts are noticeably different in composition from the others. The possibility of a pre-existing sialic basement cannot be ruled out.</p> / Thesis / Bachelor of Science (BSc)
