Primera Reservoir Ltd. strategic position analysis

The purpose of this work is to understand the internal and external structure in which the company operates to provide an idea of the strategic actions needed to accomplish their organizational objectives. A strategic software was employed to build up phase one and phase two, phase one involved analysing internal and external factors that influence the company, comprehending their core competences, factors that influence the market and identification of strengths and weaknesses. Phase two consisted on providing an idea of their real competitive position and the suggestion of a development strategy, given the possible limitations in the external factors, the company should carefully analyse some of the opportunities present in the industry overseas to continue to develop their business and increase its profitability. Furthermore, a source of competitive advantage was found in their outbound logistics which could serve a differentiator between their competitors.

Design and characterization of novel biopolymeric structure using biocompatible ionic liquids

The main objective of this thesis was the development of polymeric structures from the dissolution of FucoPol, a bacterial exopolysaccharide (EPS), in a biocompatible ionic liquid, choline acetate. The FucoPol was produced by the bacteria Enterobacter A47 using glycerol as carbon source at controlled temperature and pH (30ºC and 7, respectively). At the end of 3 days it was produced 7 g/L of FucoPol. The net yield of Fucopol in glycerol (YP/S) was 0.22 g/g and the maximum productivity 2.37 g/L.d This polymer was characterized about its composition in sugars and acyl groups (by High-Performance Liquid Chromatography - HPLC), containing fucose (35 % mol), galactose (21 % mol), glucose (29 % mol), rhamnose (3% mol) and glucuronic acid (12% mol) as well as acetate (14.28 % mol), pyruvate (2.15 % mol) and succinate (1.80 % mol). Its content of water and ash was 15% p/p and 2% p/p, respectively, and the chemical bonds (determined by Infrared Spectroscopy - FT-IR) are consistent to the literature reports. However, due to limitations in Differential Scanning Calorimetry (DSC) equipment it was not possible to determine the glass transition temperature. In turn, the ionic liquid showed the typical behavior of a Newtonian fluid, glass transition temperature (determined by DSC) -98.03ºC and density 1.1031 g/cm3. The study of chemical bonds by FT-IR showed that amount of water (8.80%) influenced the visualization of the bands predicted to in view of their chemical structure. After the dissolution of the FucoPol in the ionic liquid at different temperatures (50, 60, 80 and 100 ° C) it was promoted the removal of this by the phase inversion method using deionized water as a solvent, followed by drying in an oven at 70 ° C. The mixtures before and after the phase inversion method were characterized through the studies mentioned above. In order to explore possible application field’s biocompatibility assays and collage on balsa wood tests were performed. It was found that the process of washing with water by the phase inversion method was not totally effective in removing the biocompatible ionic liquid, since all FucoPol – IL mixtures still contained ionic liquid in their composition as can be seen by the DSC results and FT-IR. In addition, washing the mixtures with water significantly altered the composition of FucoPol. However, these mixtures, that developed a viscous behavior typical of a non-Newtonian fluid (shear-thinning), have the potential to be applied in the biomedical field as well as biological glues.

The Multidimensional and Centred Structure of Our Interested Perception in Hierocles

O objectivo desta dissertação é identificar a estrutura da percepção tal como ela é desenhada por Hiérocles nos <,(#= >1!(?$%&'(). Para alcançar este objectivo focar-me-ei na análise que o filósofo estóico leva a cabo em torno da percepção. O foco começa por incindir sobre a distinção entre percepção de si e percepção do exterior, com todas as suas subtilezas. Tal análise implicará então a consideração da importância da não-indiferença nessa estrutura de percepção. O objectivo é compreender como a percepção é sempre relacional e interessada. . Centrar-me-ei então na noção de !"#$%&'(), tentanto explorar a complexidade e multiplicidade do fenómeno em causa. Será também estabalecida a relação com o fragmento de Estobeu (6.671), que é, a par da obra, a fonte mais importante do pensamento de Hiérocles. Através desta relação introduzir-se-á a estrutura circular e concêntrica de uma percepção relacional e interessada. Toda esta dissertação será levada a cabo focando-se principalmente nos textos do próprio Hiérocles.

Corporate social reponsability strategic corporate social responsability: External and internal outcomes

This study investigates the importance and benefits of having a strategic Corporate Social Responsibility (CSR) program by testing the interrelationships between strategic CSR with three external (reputation, corporate image, and customer loyalty) and four internal (organizational commitment, job satisfaction, performance, and organizational deviance) variables. 269 clients and non-clients along with 190 employees and their direct supervisors completed the survey. Strategic CSR has shown to have a positive impact on all the variables studied with the exception of organizational deviance. Practical implications and suggestions for future research are discussed.
