O novo perfil do engenheiro civil: o profissional de síntese

O Homem tem modificado consideravelmente o meio natural e transformado profundamente as paisagens primitivas. As vias de comunicação e os aglomerados populacionais constituem referências evidentes da sua presença e denotam o percurso do homem no tempo. Neste processo de mudança contínua o papel dos engenheiros foi fundamental pois a sua prática remonta às civilizações anteriores à era Cristã da qual temos o testemunho de Arquimedes (287-212 a.C.) que foi um grande cientista e engenheiro da Antiguidade. O termo engenharia em termos semânticos tem a sua origem da palavra latina ingeniatorum significando “engenhoso na arte de projectar” (Duffell, 1990). De facto a engenharia tem sido definida como uma arte que permite que os principais recursos da natureza sejam transformados, adaptados e aplicados para o uso ou conveniência do homem (The New Caxton Encyclopedia, 1986).

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.
