Reinventing America on the battlefields of Spain or following the party line: conflicting perceptions of the Spanish Civil War in the present and in the past

Isolationism and neutrality are two of the recurrent themes in the study of the history of the U.S. foreign policy in the interwar years. The trauma of the Great War, which had swept away 130.000 U.S. lives and had cost $30 billion, had led public opinion to strongly oppose any involvement with European affairs. Besides, the urgent need for economic recovery during the dismal years of the Great Depression did not leave Roosevelt much room for manoeuvre to influence international events. His positions regarding the intentions of the Fascist states remained, at best, ambivalent. These facts notwithstanding, about 2800 U.S. citizens crossed the Atlantic and rushed in to help democratic Spain, which was on the verge of becoming one more hostage in the hands of the Fascism. They joined the other British, Irish and Canadian volunteers and formed the XV International Brigade. 900 Americans never returned home. This alone should challenge the commonly held assumption that the American people were indifferent to the rise of the Fascist threat in Europe. But it also begs other questions. Considering the prevailing isolationist mood, what really motivated them? With what discursive elements did these men construct their anti Fascist representations? How far did their understanding of the Spanish democracy correspond to their own American democratic ideal? In what way did their war experience across the Atlantic mould their perception of U.S. politics (both domestic and foreign)? How far did the Spanish Civil War constitute one first step towards the realization that the U.S. might actually be drawn into another international conflict of unpredictable consequences? Last but not the least, what ideological, political and cultural complicity existed between the men from the English-speaking battalions? In order to unearth some of the answers, I intend to examine their letters and see how these men recorded the historical events in which they took part. Their correspondence emerged from the desire to prove their commitment to a common cause and spoke of a common war experience, but each letter, in its uniqueness, ends up mirroring not only the social and political background of each individual fighter, but also his own particular perspective of the war, of world politics and of the Spanish people. We shall see how these letters differ and converge and how these particular accounts weave, as in an epistolary novel, a larger-than-life narrative of outrage and solidarity, despair and hope.

Radiographers perceptions of magnetic resonance imaging: a study of the causes that lead to the exams repetition

Purpose: To know how often occur the repetitions of MRI exams and sequences in radiology departments. Methods and Materials: A self applied-questionnaire was used as instrument and assigned to 57 radiographers who performed MRI exams to determine which were the causes that lead to the repetition. The questionnaires were interpreted and statistically analyzed through descriptive statistics and Spearman’s rho correlations. Results: At a 95% confidence interval, the major results suggest that the patient’s movement during de MRI exams is the main cause to repeat this exams (mean of 3.88 on a 5 points likert scale). However, there are causes related to the radiographer’s and the results showed that the introduction of wrong imaging parameters by the performer are a major cause too (N=26). Spearman rho correlations between radiographer’s time of experience and frequency of MRI exams repetitions were poor and not significant (r=0.141; p=0.297). The correlations between radiographer’s tiredness and frequency of MRI exams repetitions were negative, weak and not significant (r= -0.151; p=0.263). Conclusion: The patients’ movement may disrupt the examination or degrade the images with artifacts. The level of experience doesn’t influence the repetitions of MRI exams, it seems that seniors radiographers don’t have improvements in performance as it should be expected. It’s recommendable to do training courses regularly to improve the performance and systematically evaluate. Several features will need to be identified which would decrease the MRI exams repetitions.

Tourism in Timor Leste: contributions to a sustainable development

The main goal of this thesis is to analyse tourism as a contributor to sustainable development, from a supply and demand perspective, in Timor-Leste, a destination not only “young” but also framed in an early stage of touristic development. From the supply side, studies 1 and 2 present a literature review on the concept of sustainable development, in small islands destinations, its weaknesses and vulnerabilities, and whose attractiveness lies in an integrated set of natural resources (attractive beaches, biodiversity, the coral triangle, a rich fauna and flora), its geographic location, tropical climate, socio cultural tradition and a Luso-Timorense cultural mix, that can meet the needs of important segments of the tourist demand. In these studies, the focus is on the residents’ attitudes in relation to sustainable development and, in particular, on the perceptions of local leaders about the importance of the operationalization of the concept. As Timor-Leste is a “young” destination, it is travel industry is still faced with several problems in order to be able to satisfy the demand and to meet the tourists’ motivations, preferences and requirements. In this perspective, the study 3 examines diaspora tourism, while a niche market, allowing for not only the entry of Timor-Leste in the international tourism market, but also an articulation between the people of Timor-Leste in the diasporas and the development of sustainable tourism . In general, the results show that the development of sustainable tourism cannot be successfully implemented without the involvement of all stakeholders such as residents, public sector (local government, policy makers, planners), private sector (tourism operators), and non-governmental organizations (NGOs) that include civil society, religious institutions, the academic community (the supply side), and Timorese diasporas tourists as consumers (the demand side).
