Robertson, ambos economistas de Cambridge, foram intensos colaboradores intelectuais na década de 1920; mas após da publicação da Teoria geral de Keynes, em 1936, a colaboração foi substituída por uma ostensiva rivalidade teórica. O ponto de inflexão do relacionamento entre ambos, entretanto, antecede esta época, e remonta à publicação do Tratado sobre a moeda de Keynes, em 1930. A partir da resenha que Robertson fez deste livro, os autores travaram um debate teórico e terminológico, acerca de questões como a determinação do preço dos bens de investimento, a relação entre poupança, investimento e entesouramento, e a determinação da quantidade de depósitos inativos na economia. Este debate, denominado pela literatura especializada de controvérsia "dos baldes em um poço", foi considerado de importância fundamental para as futuras divergências entre os autores, mas não recebeu atenção analítica à altura desta consideração. Nesta dissertação, argumenta-se que o desdobramento dos pontos debatidos esteve em parte relacionado à necessidade de Keynes de responder às críticas de Hayek ao livro, e procura-se estabelecer um modo de correlação entre os diversos conceitos debatidos (entesouramento, depósitos inativos, nível de preço dos bens de investimento, poupança, etc.) Considerou-se, como ponto de orientação geral, a pergunta: a controvérsia foi teórica ou simplesmente terminológica? O que se constata é que não há resposta simples para esta questão. De fato, a "controvérsia dos baldes em um poço" mistura assuntos teóricos, talvez não inteiramente compatíveis entre si, e em relação aos quais a diferença entre os autores foi em parte teórica, e em parte terminológica / Abstract: John M. Keynes and Dennis H. Robertson, both economists from Cambridge, were intense intellectual collaborators in the 1920s; but after the publication of Keynes?s General theory, in 1936, their collaboration was substitutes by an ostensive theoretical rivalry. The turning point of their relationship, however, is previous from that time, and goes back to the publication of Keynes's Treatise on money, in 1930. From Robertson's review of that book on, the authors engaged in a theoretical and terminological debate, concerning matters such as the determination of the price of investment goods, the relation between saving, investment and hoarding, and the determination of the quantity of inactive deposits in the economy. This debate, named the "buckets in a well" controversy by the specialized literature, was considered to be of fundamental importance for the future divergence between the authors, but did not receive an analytical attention compatible to such consideration. In this dissertation, it is argued that the unfolding of the subjects in the debated was partially related to Keynes's need to answer Hayek's critics of his book, and the dissertation means to establish a way to correlate the many debated concepts (hoarding, inactive deposits, price level of investment goods, saving, etc.) It was considered, as a general point of orientation, the question: was the controversy theoretical, or simply terminological? It is concluded that there is no simple answer to such question. As a matter of a fact, the "buckets in a well controversy" mixes many theoretical subjects, which may not be entirely compatible one to another, and in relation to which the difference between the authors was partially theoretical, and partially terminological / Mestrado / Historia Economica / Mestre em Ciências Econômicas

No presente estudo investigou-se a existência de possíveis alterações na percepção de cores em adultos com Transtorno Depressivo Maior, utilizando-se como parâmetros os limiares de discriminação para os eixos de confusão Protan, Deutan e Tritan, a área da elipse de MacAdam e sua elipticidade. O estudo contou com 23 voluntários, sendo 11 com depressão maior (Grupo Experimental) e 12 isentos de quaisquer patologias identificáveis (Grupo Controle). Todos os participantes foram submetidos aos testes de discriminação (Cambridge Colour Test v2.0), e arranjo de cores (Lanthony Desaturated Test D-15), a fim de que fossem mensuradas e comparadas as repostas de ambos os grupos. Os resultados apontaram diferenças significativas (entre grupos Controle e Experimental) na comparação dos limiares de discriminação dos eixos testados (p < 0,05), como também para as áreas das elipses testadas, ao longo do eixo Tritan (p < 0,05). Igualmente, os resultados apontaram diferenças significativas (entre grupos Controle, Depressão Leve e Depressão Moderada/Grave) na comparação dos mesmos limiares com post-hoc para os grupos Controle e Depressão Moderada/Grave estatisticamente significante (p < 0,05). Houve também diferença significante para as áreas das elipses, bem como para o post-hoc entre Grupos Controle e Depressão Moderada/Grave (p < 0,05). Finalmente, os eixos elípticos não demonstraram diferenças significantes para nenhuma das condições entre grupos. A presente pesquisa coaduna com a suposição de que o prejuízo para sensibilidade à cor pode apresentar-se como estado ou característica dos transtornos do humor, dada a conclusão do presente trabalho ao encontrar que pacientes com transtorno depressivo maior podem apresentar alterações na capacidade discriminativa de cores, quando comparados com voluntários saudáveis.

The Facebook - Cambridge Analytica scandal came to light in 2018 revealing the problematic surveillance practices, and violations of privacy the companies allowed. The EU has introduced a privacy legislation, GDPR, that came into effect in 2018 shortly after the scandal erupted. Privacy is a key problem with modern technologies, as companies are trying to gain all possible data on individuals. The purpose of this thesis is to explore the surveillance-privacy nexus in the EU. This thesis asked the research question of: How has surveillance, through emerging technologies, affected the EU's ability to protect the right to privacy? To analyse this research question, this thesis used case study and post-structuralist discourse analysis on the recordings of Alexander Nix, CEO of Cambridge Analytica, at a marking festival, and of Mark Zuckerberg at the European Parliament. To analyse the recordings, biopower and panopticon were used as core theoretical tools. Through utilization of the methods and the theoretical tools, the findings of this thesis point to the conclusion that the EU’s ability to protect privacy from surveillance practices was not affected by the modern surveillance technology, and therefore the protection against exploitation of privacy remains low.

The work presented herein focus upon crystal engineering of nutraceutical cocrystals. Cocrystals are considered unique solid dosage form which has many advantages over other traditionally known solid forms. Furthermore, cocrystals have proven to improve stability, solubility and bioavailability of Active Pharmaceutical Ingredient (API) as shown in the case of carbamazepine and other APIs in previous studies. Crystal engineering is commonly used to design new solid forms based on the bases of supramolecular chemistry. In this study, crystal engineering based on intensive Cambridge Structural Database (CSD) analysis used to predict and design new cocrystals of targeted nutraceuticals. Two nutraceuticals were selected for this study; resveratrol and citric acid. The rationale behind selecting resveratrol was to improve its solubility and, accordingly, bioavailability. On the other hand, citric acid is known as a highly soluble and safe nutraceutical, and thus it can be used as a coformer. Five new cocrystals were prepared and characterized using a variety of techniques that include single crystal X-ray diffraction (XRD), powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), FT-IR, and thermo-gravimetric analysis (TGA). Most of the reported cocrystals were obtained using different techniques; solvent slow evaporation, mechanichemical approach, slurry, and from melt. Moreover, dissolution test has been performed on resveratrol and two of its cocrystals, using UV-vis spectrophotometer, where the data demonstrate that through cocrystallization with different cocrystal formers, solubility of resveratrol could be greatly modified, and further controlled. The polymorphism phenomenon is encountered, and accordingly addressed, herein where four novel polymorphs were obtained during cocrystallization attempts. Polymorphism has a significant importance in industry, in general, and in pharmaceutical industry, in particular, due to the vast differences in physical properties of polymorphs. Furthermore, the study of polymorphism provides valuable information essential to understand how different crystal forms are attained.

Rationale Cognitive deficits are now recognised as a major symptom of schizophrenia with a number of studies reporting profound deficits in cognitive function in both chronic and first episode patients. Recent advances in cognitive remediation therapy have provided the opportunity for patients to improve their cognitive function and therefore improve their functional outcome. Aim The aim of the present study was to investigate cognitive deficits using the Cambridge Neuropsychological Test Automated Battery (CANTAB®) in first episode psychosis and chronic schizophrenia patients. In the first episode population the effect of ethnicity on cognition was also examined. In the chronic schizophrenia study comparisons between severity of deficits with first episode psychosis patients were also made. The effects of cognitive remediation therapy were also examined in a sample of first episode patients. Methods A total of 35 patients and 30 healthy controls were recruited into the first episode study, 17 patients and 17 controls into the chronic schizophrenia study and 11 patients into the cognitive remediation study. The first episode psychosis patients were recruited from the Bradford and Airedale Early Intervention Service and the chronic patients from the Leeds Partnership NHS Foundation Trust. The control subjects were matched as closely as possible in terms of intelligence and demographics to the patient groups. The Wechsler Test of Adult Reading (WTAR) was used to estimate subjects pre-morbid IQ. The severity of symptoms was assessed using the Positive and Negative Syndrome Scale (PANSS). All subjects who took part in the study completed a comprehensive battery of neuropsychological tests from the CANTAB®. Patients in the cognitive remediation study participated in group therapy sessions using X-cog®. Results There were no significant differences found between There were no significant differences found between patients and controls in relation to intelligence or demographics in all studies. The effect of ethnicity was shown to be not significant in the first episode study. Results show that patients performed significantly worse than controls across all iv cognitive domains tested in all studies. A correlation between negative symptoms and executive function was found in both first episode and chronic schizophrenia patients. Comparisons between first episode psychosis and chronic schizophrenia patients in cognition showed no significant differences, however significant differences were found in levels of negative symptoms and age between the two groups with chronic patients scoring higher on negative symptoms and being older. In the cognitive remediation study a significant improvement was observed in patients in the domain of executive function and a reduction in negative symptoms following completion of the intervention. Conclusion First episode and chronic schizophrenia patients display significant cognitive deficits across all domains when tested using the CANTAB®. Some of these deficits appear to be independent of the length of the illness but dependent on negative symptoms. This study demonstrates that cognitive deficits exist across all patient groups regardless of age, gender, pre-morbid IQ, years in education and ethnicity. Cognitive remediation therapy has also been shown to be effective in improving cognitive functioning in patients.
