Camaradas caretas: drogas e esquerda no Brasil após 1961 / Uncool fellows: drugs and leftist organizations in Brazil after 1961

Júlio Delmanto 18 March 2013 (has links)
Enquadradas arbitrariamente no mesmo termo generalizante drogas, diversas substâncias psicoativas de diferentes efeitos e tradições foram proibidas a partir do começo do século XX por conta de interesses morais, econômicos e políticos justificados por um questionável discurso defensor da saúde pública. A proibição destas substâncias não incidiu sobre seus possíveis efeitos danosos e trouxe consigo uma série de outrosproblemas, como violência do crime e do Estado, corrupção, criminalização da pobreza,encarceramento em massa,ingerência imperial sobre territórios desejados e ingerência estatal sobre a vida privada dos cidadãos. Mesmo assim, com algumas exceções, a questão não ocupou lugar de destaque nos programas e na atuação das organizações de esquerda no Brasil, que invariavelmente ignoraram esta questão, quando não se posicionaram favoravelmente ao proibicionismo. Inspiradas em ideais de hierarquia, disciplina e sacrifício militante,e considerando o uso depsicoativosmajoritariamentepela chave explicativa da fuga da realidade, estas organizações tiveram pouca sensibilidade para propor outros meios que não o repressivo e o penal para se lidar com problemas decorrentes do abuso no uso de drogas, e menos vezes ainda para lidar com formas alternativas de exploração das tecnologias de si, como definiu Michel Foucault. Além de traçar um panorama das origens da proibição das drogas e seus efeitos, este trabalho investiga que tipo de tratamento foi dado pela esquerda à questão das drogas após 1961 ano tanto da aprovação da Convenção Única sobre Narcóticos, da ONU, quanto dos primeiros rompimentos com o PCB, processo que representou uma reconfiguração na esquerda brasileira. / Arbitrarily framed in the same generalizing term \"drugs\", several different psychoactive substances, with different traditions and effects were prohibited in the early twentieth century -because of moral, economic and political interests, justified by a questionable speech defender of \"public health.\" The prohi bition of these substances did not influence in their possible harmful effects and brought with it a lot of other problems, such as crime and violence of the State, corruption, criminalization of poverty, mass incarceration, imperial interference on desired territories and state interference on the citizens private lives. Yet, with few exceptions, the subject did not occupy a prominent place in programs and activities of leftist organizations in Brazil, which most of the time ignored this question. Inspired by the ideals of hierarchy, discipline and militant sacrifice, and considering the use of psychoactive drugs mostly by the explication of \"escape from reality\", these organizations have had little sensitivity to propose other means than the repressive and penal to deal with problems arising from drug abuse, and even less often to deal with alternative ways of operating \"technologies of the self,\" as defined by Michel Foucault. Besides from giving an overview of the origins of drug prohibition and its effects, this study investigates what kind of treatment was given to the issue of drugs by the brasilian left after 1961 -the year of the adoption of the Single Convention on Narcotic Drugs of the United Nations, and also of the first splits in the brasilian comunist party (PCB), which represented a reconfiguration process in the brazilian left.

A irmandade fraturada: a relação entre os intelectuais de esquerda e as camadas populares no filme Quase dois irmãos (Lúcia Murat, 2005) / The fractured brotherhood: the relationship between the left intellectuals and the popular layers in the film Almost two brothers (Lúcia Murat, 2005)

Grazieli Chirosse Batista 18 October 2017 (has links)
Esta dissertação visa analisar a representação do relacionamento entre os intelectuais de esquerda e as camadas populares na obra cinematográfica Quase dois irmãos (Lúcia Murat, 2005). O filme representa, a partir de uma narrativa dramática, aspectos fundamentais das relações entre a classe média e as camadas populares. Através de três espaços temporais, década de 1950, 1970 e anos 2000, o contato entre a classe média e o morro carioca, são representadas as perspectivas dos intelectuais de esquerda referente a aproximação com o povo entre décadas de 1950 e 1970. O golpe militar de 1964 interromperia o momento de construção de projeto cultural de revolução social engendrado pelos intelectuais de esquerda, acirrando as tensões existentes entre os dois ethos sociais. Esta pesquisa busca compreender como essa construção ficcional, enquanto criação artística da diretora Lucia Murat, sedimenta na forma cinematográfica determinada compreensão do mundo, conectada à memória da ditadura militar de setores da esquerda brasileira. Configura-se uma fonte documental importante pela experiência histórica que está condensada em sua narrativa, assim como em sua estrutura estética que ratifica os movimentos históricos de permanência e cisão expostos no filme e possibilita reflexões sobre relações e problemas sociais e raciais no Brasil. / This dissertation aims to analyze the representation of the relationship between the left intellectuals and the popular strata in the cinematographic \"Almost brothers\" (Lúcia Murat, 2005). The film represents, from a dramatic narrative, fundamental aspects of the relationships between the middle class and the popular strata. Through three timelines, the 1950, 1970 and 2000 years, the contact between the middle class and the carioca Hill, are represented the perspectives of left-wing intellectuals for rapprochement with the people between 1950 and 1970 decades. The military coup of 1964 would interrupt the moment of construction of cultural project of social revolution engendered by leftist intellectuals, intensify existing tensions between the two social ethos. This research seeks to understand how this fictional construct, while artistic creation of director Lucia Murat, forms a sediment in cinematic form determined understanding of the world, connected to the memory of the military dictatorship of sectors of the brazilian left. Configures a document source important for historical experience that is condensed into your narrative, as well as in your aesthetic structure that ratifies the historical movements of permanence and spin-off exposed in the film and provides reflections on relationships and problems racial and social in Brazil.

Avaliação da linguagem após hemisferectomia de hemisfério cerebral esquerdo / Language assessment after left hemispherectomy

Jocelí Rodrigues da Silva 14 April 2016 (has links)
A hemisferectomia esquerda é um procedimento cirúrgico indicado em casos de epilepsia fármaco-resistente com foco epileptogênico em hemisfério cerebral esquerdo. Os benefícios potenciais da cirurgia, além do controle de crises, podem ser observados também nos âmbitos comportamental e cognitivo, fazendo com que seja uma boa alternativa nos casos de epilepsia refratária aos medicamentos. Apesar de suas vantagens, o procedimento ainda não é amplamente indicado, em parte devido ao receio de piora dos déficits motores previamente instalados e principalmente das funções corticais superiores, dentre elas, a linguagem. Neste estudo retrospectivo foram avaliados os prontuários de 15 crianças e adolescentes com idades entre 6 e 18 anos à época da realização da hemisferectomia funcional esquerda (HFE). Nessa faixa etária, segundo teorias, já ocorreu a transferência da linguagem para o hemisfério dominante esquerdo, na maioria dos indivíduos. A idade na época da cirurgia variou entre 6,6 e 15 anos, média 10,6 anos. A idade de início das crises epilépticas variou de zero a 12 anos, média 4,25 anos. A duração média da epilepsia até a data da intervenção cirúrgica foi de 6,3 anos (um a 12,7 anos). As frequências etiológicas por grupos foram: 20% de malformação do desenvolvimento cortical, 40% de lesões adquiridas e estáticas e 40% de doenças progressivas (encefalite de Rasmussen). O objetivo deste estudo foi avaliar o desfecho da linguagem em crianças e adolescentes submetidos à HFE após o período de transferência da linguagem. A função foi avaliada através do quesito domínio da comunicação na Escala de Vineland ou através do QI verbal em crianças submetidas ao WISC (Escala de Inteligência Weschler para Crianças). A linguagem apresentava-se parcialmente desenvolvida em todos os pacientes avaliados, nenhum deles tinha esta função plenamente desenvolvida. A hemisfererectomia funcional do hemisfério cerebral esquerdo não causou repercussão sobre a linguagem de crianças e adolescentes com epilepsia de difícil controle medicamentoso. Uma possível explicação para esse resultado refere-se à plasticidade cerebral, essa importante capacidade de remodelação e recuperação das funções cerebrais, além da possibilidade de transferência da linguagem para o hemisfério cerebral direito em casos de lesões em áreas da fala em hemisfério cerebral esquerdo. Este resultado corrobora a importância do encaminhamento de crianças portadoras de epilepsia refratária aos medicamentos antiepilépticos o mais precocemente possível a centros especializados para avaliação e possível indicação desse procedimento, uma vez que assim impedirá ou minimizará os efeitos da encefalopatia epiléptica progressiva sobre a cognição e principalmente sobre a linguagem / The left hemispherectomy is a surgical procedure indicated in cases of medically refractory epilepsies with epileptogenic focus in the left cerebral hemisphere. The benefits of surgery, in addition to seizure control can also be observed in behavioural and cognitive spheres, making it a good alternative in cases of refractory epilepsy. Despite its advantages, the procedure is not yet widely indicated, partly due to fear of worsening of pre-installed motor deficits and especially of higher cortical functions, including the language. In this retrospective study, we evaluated the medical records of 15 children and adolescents aged between 6 and 18 years at the time of left functional hemispherectomy. In this age range, according to theories, the transfer of language for the left dominant hemisphere has occurred in most individuals. The age at time of surgery ranged between 6.6 and 15 years, mean 10.6 years. The early observation of seizures ranged from zero to 12 years, mean 4.25 years. The mean duration of epilepsy until the surgery was 6.3 years (one to 12.7 years). The etiological frequencies by groups were: 20% of malformation of cortical development, 40% of acquired and static lesions and 40% progressive disease (Rasmussen\'s encephalitis). The aim of this study was to evaluate the outcome of language in children and adolescents undergoing left hemispherectomy after the language transfer period. The function was evaluated through the item field of communication in Vineland Scale or through verbal IQ in children submitted to WISC. The language had partially developed in all patients, but none of them had fully developed this function. The left functional hemispherectomy caused no impact on the language of children and adolescents with refractory epilepsy. A possible explanation for this result refers to brain plasticity, this important ability to remodelling and recovery of brain functions and the possibility of transfer of language to the right cerebral hemisphere in cases of lesions in speech areas in the left cerebral hemisphere. This result confirms the importance of referral of children with refractory epilepsy as early as possible to specialized centers for evaluation and possible indication of this procedure, as well prevent or minimize the effects of progressive epileptic encephalopathy on cognition and especially on language

Neste estudo investigamos a associação entre dados espirométricos e ecocardiográficos em indivíduos hipertensos não fumantes. Num estudo transversal, 107 pacientes hipertensos (60 mulheres) foram avaliados por análises clínicas, hemodinâmicas, laboratoriais e ecocardiográficos. A capacidade vital (CV), a capacidade vital forçada (CVF), o volume expiratório forçado no primeiro segundo (VEF1), o volume expiratório forçado no sexto segundo (VEF6) e a relação VEF1\CVF foram medidos através de espirometria. Nas mulheres, o índice de massa do VE e a relação E\Em correlacionaram-se com variáveis espirométricas, enquanto que a espessura relativa da parede somente se correlacionou com o percentual de CVF previsto. Nos homens, somente o índice de massa do VE se correlacionou com variáveis espirométricas. Análise de regressão tipo stepwise mostrou que o índice de massa do VE não esteve associado com nemhum parâmetro espirométrico após ajuste para os potenciais confundidores nos homens, enquanto que CVF e VEF6 se associaram de maneira significativa com a massa do VE e a relação E\Em no sexo feminino. Entretanto, marcadores inflamatórios tais como Proteína C reativa plasmática e os níveis séricos de metaloproteinases 2 e 9 não influenciaram estas associações. Em conclusão, o declínio na função pulmonar está independentemente associado com maior massa e pior função diastólica do VE em mulheres hipertensas / Abstract: Hypertensive patients are predisposed to left ventricular (LV) remodeling and frequently exhibit decline in lung function as compared to the general population. Here, we investigated the association between spirometric and echocardiographic data in non-smoking hypertensive subjects. In a cross-sectional study, 107 hypertensive patients (60 women) were evaluated by clinical, hemodynamic, laboratory and echocardiographic analysis. Vital capacity, forced vital capacity (FVC), forced expired volume in 1s (FEV1) and in 6s (FEV6) and FEV1/FVC ratio were estimated by spirometry. In women, LV mass index and E/Em ratio correlated with spirometric variables, while relative wall thickness only correlated with the percentage of predicted FVC. In men, only LV mass index correlated with spirometric variables. Stepwise regression analysis showed that LV mass index did not associate with any spirometric parameter after adjustment for potential confounders in men, while markers of restrictive and obstructive lung dysfunction, such as reduced FVC and FEV6, were significantly associated with LV mass and E/Em ratio in women. Furthermore, inflammatory markers such plasma C-reactive protein and matrix-metalloproteinases-2 and -9 levels did not influence these associations. In conclusion, decline in lung function is independently associated with higher LV mass and worse LV diastolic function in hypertensive women / Mestrado / Clinica Medica / Mestre em Clinica Medica

No. of bitstreams: 1 Ludovico_NelsonDinamarco_D.pdf: 11127350 bytes, checksum: fac2a775e3c6969068fdbd9ca7d14542 (MD5) Previous issue date: 2012 / Resumo: A hipertrofia ventricular esquerda caracterizada como lesão de órgão alvo aumenta o risco de morbi-mortalidade de 5 a 9 vezes quando presente. A detecção precoce da HVE permite a identificação de pacientes com risco, além de permitir a intervenção de forma precoce, melhorando o planejamento estratégico para o seu manejo. A hipertensão arterial resistente é caracterizada pelo paciente, que mesmo em uso de três medicações em doses otimizadas, sendo um deles diurético, ainda se mantém fora das metas preconizadas. Vários métodos diagnósticos de hipertrofia estão disponíveis para o diagnóstico da HVE, entre eles se destaca o ecocardiograma com elevada sensibilidade, especificidade e acurácia, o eletrocardiograma, com elevada especificidade, porém baixa sensibilidade e acurácia, em contrapartida com excelente reprodutibilidade e baixo custo operacional, e fácil realização, inclusive em locais afastados dos grandes centros, em contraposição ao ecocardiograma. Outro método, não muito usado na prática clínica, o vetorcardiograma, pode atualmente, ser realizado no mesmo equipamento do eletrocardiograma, justificando assim a sua empregabilidade na prática clínica diária. Apresentou em nosso estudo a mesma baixa sensibilidade e acurácia que o eletrocardiograma, compatíveis com estudos publicados recentemente, porém a associação de dois critérios, um eletrocardiográfico e outro vetorcardiográfico melhorou a sensibilidade e acurácia na detecção da hipertrofia ventricular esquerda, sem prejuízo para a especificidade, com valores próximos ao ecocardiograma / Abstract: Left ventricular hypertrophy characterized as target-organ damage increases the risk of morbidity and mortality 5-9 times when present. Early detection of LVH allows the identification of patients at risk, and allows intervention at an early stage, improving strategic planning for its management. The resistant hypertension is characterized by the patient, even taking three medications in doses optimized, one being a diuretic, is still outside of the recommended goals. Several diagnostic methods are available to hypertrophy the diagnosis of LVH, including echocardiography stands out with high sensitivity, specificity and accuracy, the electrocardiogram, with high specificity but low sensitivity and accuracy, in contrast with excellent reproducibility and low operating cost, and easy to perform, even in places far from the large centers, in contrast echocardiography. Another method, not widely used in clinical practice, the vectorcardiogram, can now be performed on the same equipment on the electrocardiogram, thereby justifying their employability in daily clinical practice. In our study vectorcardiography presented the same low sensitivity and accuracy than electrocardiography, consistent with recently published studies, but the combination of two criteria, an electrocardiogram and other vetorcardiográfico improved sensitivity and accuracy in detecting left ventricular hypertrophy, without prejudice to the specificity, with values close to echocardiography / Doutorado / Farmacologia / Doutor em Farmacologia

Estudo morfoquantitativo do miocárdio do ventrículo esquerdo de ratas ooforectomizadas submetidas a exercício aeróbico / Morphoquantitative Study of Myocardium of Left Ventricle of Ooforectomized Rats Submitted to Aerobic Exercise

Amanda Messias Vazzoler 21 July 2008 (has links)
Diversos estudos indicam que a deficiência de estrógeno aumenta a incidência de doenças cardiovasculares em mulheres na pós-menopausa. Os efeitos decorrentes da deprivação de estrógeno no miocárdio ainda não estão totalmente esclarecidos. Estudos têm evidenciado efeitos benéficos da atividade física no sistema cardiovascular, em qualquer condição, em especial na menopausa. Utilizando ratos Wistar, como modelo experimental, os objetivos deste trabalho são: a) verificar se a ooforectomia e a atividade física produzem alterações no miocárdio do ventrículo esquerdo, b) verificar se a realização do exercício físico aeróbico tem efeito sobre essas alterações. Para a realização deste estudo foram utilizadas 15 ratas com 6 meses de idade, da linhagem Wistar, distribuídas em 3 grupos de 5 ratas cada: GC- Ratas com 6 meses de idade sem ooforectomia e sem atividade física; GS- Ratas com 6 meses de idade com ooforectomia bilateral sem atividade física; GA- Ratas com 6 meses de idade com ooforectomia bilateral que realizaram atividade física (corrida em esteira) durante 3 meses. Os animais dos 3 grupos foram eutanasiados com 9 meses de idade. A avaliação foi realizada através de microscopia de luz e estereologia. Os cortes histológicos foram corados por: Hematoxilina-Eosina e Picrosírius. Na parede do ventrículo esquerdo foram estimadas as densidades de volume dos cardiomiócitos, do tecido conjuntivo e a densidade de comprimento e densidade de volume dos vasos intramiocárdicos. Foi estimado o número total de núcleos de cardiomiócitos e sua densidade numérica foi estimada através do método disector. Os dados quantitativos dos três grupos foram estatisticamente comparados através do ANOVA e teste de Tukey. Os resultados mostraram que houve um aumento de peso nos animais do GS e GA em relação ao GC. Quanto ao treinamento, os animais do GA tiveram melhor rendimento nos TEMs. Quanto ao volume do VE, observamos uma diminuição, embora não significante, nos animais do GS e GA em relação ao GC. A densidade de volume dos vasos intramiocárdicos foi maior no GC que no GA. As diferenças não foram estatisticamente significantes em relação à ooforectomia e ao exercício físico para os parâmetros: densidade de volume dos cardiomiócitos e do tecido conjuntivo, densidade de comprimento dos vasos intramiocárdicos, densidade numérica dos núcleos dos cardiomiócitos, número total de núcleos de cardiomiócitos e densidade numérica do colágeno. Esses dados nos levam a concluir que a ooforectomia acarreta alterações no volume do ventrículo esquerdo e a atividade física diminui a densidade de volume dos vasos intramiocárdicos. Quanto aos outros itens, nem a ooforectomia, nem a atividade física, isoladamente ou associada, parecem influenciar de maneira significativa nestes dados. / Severals studies indicate that the estrogen deficiency increase the incidence of the cardiovascular diseases in women in the post-menopausal period. The effects of the estrogen deprivation in the myocardium still remain unclear. Studies have proved beneficial effects of the physical activity in the cardiovascular system, especially in the menopause. Using Wistar rats, as an experimental model, the aims of this work are: a-) to check if the ooforectomy and the physical activity produce alterations in the left ventricle of the myocardium; b-) to check if the aerobic exercise realization affects these alterations. To achieve these goals it was used 15 Wistar rats of 6 months of age, distributed in 3 groups of five rats each: Control group- Rats with six months of age without ooforectomy and physical activity; GS- Rats with six months of age with ofoorectomy bilateral and without physical activity and, GA- Rats with six months of age with ooforectomy bilateral and physical activity during 3 months. Al rats were euthanasied with 9 months of age. The results were obtained by using light microscopy were and stereology. The histological section was stained with Hematoxylin and Eosin, and Picrosirius stain. On the wall of the left ventricle were estimated the density of volume of the cardiomiocyt, of the connective tissue and the density of length and the density of volume of the intramyocardial vessels. It was estimated the total number of nuclei of cardiomiocyt and its numerical density was estimated a cross the disector method. The data of the three groups were statistically compared for the ANOVA and Tukey´s test. The results showed that there was an increase in the weight in the animals of GS and of GA. In relation to training, the animals of GA obtained the best income in the TEMs. In relation to the volume of the left ventricle, it was observed a decrease, although not significant, in the animals of GS and GA. The density of volume of the intramyocardial vessels was higher in the GC than GA. In relation to the ooforectomy and the physical exercise for the items: density of volume of the cardiomiocyt and of the connective tissue, density of length of the intramyocardial vessels, numerical density of nuclei of cardiomiocyt, total number of nuclei of cardiomiocyt and numerical density of collagen, the differences werent significant. We can conclude that the ooforectomy result in changes in the volume of the left ventricle and that the physical activity decrease the density of volume of the intramyocardial. In relation to the other items, neither the ooforectomy, neither the physical activity, alone or together, seem doesn\'t affect these data.

Contribution à l'étude de la désadaptation cardiovasculaire à l'effort : évaluation des pressions de remplissages à un faible niveau de charge et réponse cardio-circulatoire lors d'un exercice dynamique maximal / Impairment of cardiovascular reserve during exercise : study of left ventricular filling pressures at a low workload and global cardiovascular response to maximal exercise

Hammoudi, Nadjib 12 December 2016 (has links)
L’altération de la réserve fonctionnelle cardiovasculaire (CV) à l’exercice est un signe précoce d’insuffisance cardiaque (IC). Nous avons étudié l’hypothèse d’une altération de la réserve CV dans deux modèles physiopathologiques : -une étude des pressions de remplissages du ventricule gauche (VG) lors d’un exercice de faible intensité avait pour finalité de démasquer une anomalie cardiaque latente au repos; cette approche a été appliquée à des patients à risque élevé d’IC à fraction d’éjection préservée.-une étude plus approfondie de la réponse CV au cours d’un exercice maximal avait pour double objectif, de démasquer, mais aussi d’analyser en détail les composantes physiopathologiques de l’altération de la fonction cardiaque. Cette approche a été appliquée à l’étude de la drépanocytose, un modèle de cardiopathie à haut débit. Dans la première partie de ce travail, nous avons montré qu’il était possible de démasquer une altération du remplissage VG dès une faible intensité d’exercice. Ces résultats observés initialement en utilisant des outils non-invasifs ont été confirmés en utilisant le cathétérisme cardiaque comme gold standard. Dans la seconde partie de ce travail, l’évaluation de patients drépanocytaires au cours d’un exercice maximal a permis de mettre en évidence une altération de la réserve fonctionnelle CV liée à un défaut de la réserve chronotrope et de la réserve en pré-charge du VG.Nos travaux constituent une contribution à l’étude de la physiopathologie CV. Les différentes modalités d’exploration qui ont été utilisées, et qui ont pour certaines été mises au point pour la réalisation de cette thèse, pourraient servir à l’étude d’autres cardiopathies. / Despite normal investigations at rest, latent heart failure can be observed in a number of patients during exercise. We investigated the hypothesis of an impairment of cardiovascular reserve in two pathophysiological models: - in patients at high risk of heart failure with preserved ejection fraction, we measured left ventricular filling pressures at low exercise level in order to unmask early stages of left ventricular diastolic dysfunction;- moreover, using combined echocardiography and cardiopulmonary exercise testing, a comprehensive study of cardiovascular response to maximal exercise was performed in patients with sickle cell anemia which was chosen as a model of chronic high-output states. We showed that very low exercise level could unmask early stage heart failure with preserved ejection fraction. These results, initially observed using Doppler echocardiography, were confirmed by direct invasive measurement of left ventricular filling pressure during exercise. In patients with sickle cell anemia, we found a decrease of cardiac output response to exercise. This alteration of cardiovascular reserve was characterized by a chronotropic incompetence and a blunted left ventricular preload reserve. The pathophysiological data provided by our studies may help improve and optimize management of patients with heart failure. The stress protocols which have been developed and used in our investigations could be useful to study other models of heart diseases.

The Right under the second Spanish Republic, 1931-1936, with special reference to the CEDA

Robinson, Richard Alan Hodgson January 1968 (has links)
The thesis which follows is, as the title suggests, a general study of the Right in Spain from the beginning of the Second Republic in April 1931 until the outbreak of the Civil War in July 1936. Pride of place has been given to the <u>CEDA</u> (and its antecedents <u>Acción Nacional</u> and <u>Acción Popular</u>) because this was the biggest and most important of the parties of the Right during the Republic. The terra 'Right' has been taken to signify those parties which did not proclaim themselves Republican, i.e. principally the Catholic CEDA, the Monarchist groups and the 'Fascist' <u>Falonge</u>. Consideration has also been given to two important institutions usually believed to be 'on the Right': the Church and the Army. Although some information on the Right has appeared in various books, no attempt at a comprehensive study has hitherto been made. Galindo Herrero's <u>Los partidos monárquicos bajo la aegunda República</u> (1936) deals inadequately with the Monarchist parties. Professor Payne'a study of the <u>Falange</u> does not satisfactorily place the movement in the context of the other Rightist movements with which it quarrelled or was from time to time connected. The same author's work on the Army (<u>Politics and the Military in Modern Spain</u>), was published just before this thesis went to the typist, as were the biographies of Franco by Crosier and Hills. Professor Sánchez's book on the Church and the Republic, <u>Reform and Reaction</u>, appeared in 1964, two years after work on this thesis began. Concentration on the <u>CEDA</u> in this thesis is felt by the writer to be fUlly justified, not only because of that party's size and importance for the history of the Republic, but also because it has hitherto been so neglected by historians. Only one book in any language deals with it - Monge Bernal's <u>Acción Popular</u> - and it is an 'authorized' history written by a party member at the end of 1935. Neglect of the party's history is perhaps attributable to the fact that its leaders were <u>personae non gratae</u> both to the Left and to the victors in the Civil War. The purpose of this thesis is therefore to try and provide a comprehensive study of the Right during the Republic. The thesis endeavours to explain why the various parties existed, to trace the development of each of them and to give an account of relations between them. The attitude of each to the Church and to the Army (and <u>vice versa</u>) is also discussed. An attempt is also made to examine and explain the policies, ideology and strength of each and, so far as is possible, to indicate socially and geographically whence came their supporters. The absence of adequate biographical information has however hindered a proper study of the economic interests represented by them. This thesis also constitutes an attempt to set the Right's activities firmly within the broader context of the history of the Republic and the events leading up to the Civil War. For this reason the chronological approach adopted would seem to be justified: the events of the years 1931-1936 in Spain are comparable in their complexity to those of, for example, the years 1789-1799 in France. Furthermore, the activities and development of the Right were to a considerable extent dictated by this kaleidoscopic sequence of events in which, by and large, the Left held the initiative.

Motstånd mot den Europeiska Unionen ur flera åsiktsdimensioner : En statistisk studie om vilka värderingar som driver EU-kritik i Europa / Resistance towards the European Union in mutiple dimensions : A statistical study of which values that drives EU-sceptical opinion in Europe

Hedlund Kancans, Alexander January 2017 (has links)
The purpose of this study is to investigate to what extent skeptical attitudes towards the European Union is driven by materialistic-, postmaterialist values and populism in different parts of Europe. To achieve this aim, the study is based on multivariate regression analysis with data utilized from the European Social survey 2014. The findings show that cultural questions associated with TAN values, such as a nationalistic resistance towards immigration, have the best ability to predict EU-skepticism over economic questions related with a subjective placement on the political left-right scale, or populism associated with a lack of trust in the state of political governance. These findings suggest that the subjective left-right scale do not structure attitudes toward the European Union to a great extent. Instead, the results of this study are in line with scholars that argue that the TAN-GAL scale as well as populism have grown in importance, as these axes of competition are both more linked with opinions on EU. These results hold for all regions in Europe that are examined in this study, although particular strong effects are found in Germany, where populism and TAN values shape attitudes towards EU to the greatest extent.
