Orientador: Clodoaldo Bueno / Banca: Janina Onuki / Banca: Milton Carlos Costa / Resumo: No final do século 19, nos anos que se sucederam à Guerra Civil, os Estados Unidos se consolidaram como nação industrial e também vivenciaram, como a Europa e o Japão, os problemas causados pela super-produção e pela gradual escassez de recursos naturais. Em busca de uma solução para tais dificuldades e a despeito de seu discurso isolacionista e liberal, os Estados Unidos iniciaram um processo expansionista que gradualmente estendeu sua influência econômica, política e cultural por todos os continentes. Um novo tipo de domínio, esse expansionismo se consolidou como resultado de uma conjuntura histórica, ideológica, tecnológica e religiosa e caracterizou-se por não ter limites, nem fronteiras; por englobar a totalidade do espaço do mundo e por penetrar na vida das populações subjugadas, não apenas nas suas relações com a grande potência, mas também em seus corpos, mentes, ideários e religiosidade. No passado, nenhuma ordem política ocupou tantas dimensões ou exerceu tanto controle sobre o mundo. A velha sociedade disciplinar tradicional e seus valores políticos foram substituídos por uma nova sociedade de controle e a hegemonia norte-americana passou a ser consolidada por uma rede de bases militares espalhadas por todos os continentes e por meio de sofisticados sistemas de comunicação e informações, além de atividades de enquadramento com coerção militar. Este estudo pretende aprofundar o conhecimento sobre essa nova forma de expansão e domínio, concentrando-se na teoria política do realismo, no fortalecimento do militarismo nos Estados Unidos e nas relações existentes entre o governo e o grande conglomerado das industrias da defesa instalado no país. / Abstract: In the end of the 19th century, after the Civil War and its consolidation as an industrial power, the United States also suffered the consequences caused by overproduction. Looking for a way out of it and in spite of its isolacionism and politicals critics on European imperialism, the United States ingeniously began its own imperial expansion, favored by military events which allowed them to incresase its economical, political and cultural influence all over the world. The expansion performed by the United States is a form of dominance that emerged in the last decades as result of political and military interests, added to all technological transformations that humanity has been through, being quite distict from the political power exercised over men in past eras: it has no limits or frontiers; it comprises all the world and involves the lives of entire populations, affecting their bodies, minds, ideals and religiosity. Never before a political order has taken such a dimension or has exercised such a control over the world. In this context, the old and traditional disciplinary society and its political conventions had to give way to a new society of control, ready to rule all over people through a net of defensive military basis set quietly and regularly over all continents, and through communications systems, high-tech information nets and deadly potent armaments. This work is, therefore, dedicated to collect data and explain the historical evolution of this expansion and is focused in the connection among the political theory of realism, the escalation of militarism in the United States and in the close relations that tie some sectors of the government to the economical conglomerate of defense industries. / Mestre

<p>Sexual conflict can lead to antagonistic coevolution between the sexes, but empirical examples are few. In this thesis secondary sexual characters in diving beetles are interpreted in the light of sexual conflict theory. Whether the male tarsal suction cups and female dorsal modifications are involved in a coevolutionary arms race is tested in two ways. First eight populations of a species with dimorphic females that varied in frequency of the morphs were investigated and male tarsal characteristics quantified. The frequency of female morphs is shown to be significantly correlated to the average number and size of male tarsal suction cups in the population, a prediction of the arms race hypothesis. Second, the hypothesis is tested in a phylogenetic perspective by optimizing the secondary sexual characters on a phylogeny. A full taxonomic revision of the genus <i>Acilius</i> is presented, including new synonyms, lectotype designations, geographic distributions based on more than five thousand examined museum specimens and the description of a new species from northeastern USA. Specimens of all species (except one possibly extinct that failed to be found in Yunnan, China 2000), were field collected between 2000 and 2003 in Sardinia, Sweden, Russia, Honshu and Hokkaido in Japan, New York, Maryland, California and Alberta. Three genes (CO1, H3 and Wingless) were sequenced from the fresh material as well as scoring a morphological character matrix all of which was used to derive a robust and complete hypothesis of the phylogenetic relationship in the group. The phylogeny was derived using Bayesian phylogenetics with Markov Chain Monte Carlo techniques and received a posterior probability of 0.85. Changes in male and female characters turned out to be perfectly correlated across the phylogeny, providing one of the best empirical examples to date of an antagonistic arms race between the sexes in a group of organisms. Finally, a review of a pitfall to phylogenetic analysis known under the name long-branch attraction (LBA), is provided. The problem is well known theoretically but has been questioned to occur in real data, and LBA has been in the core center of the hard debate between parsimony and likelihood advocates since different inference methods vary in sensitivity to the phenomenon. Most important conclusions from the review are; LBA is very common in real data, and is most often introduced with the inclusion of outgroups that almost always provide long branches, pulling down long terminal ingroup branches towards the root. Therefore it is recommended to always run analyses with and without outgroups. Taxon sampling is very important to avoid the pitfall as well as including different kind of data, especially morphological data, i.e. many LBA-affected conclusions have recently been reached by analyses of few taxa with complete genomes. Long-branch extraction (incl. outgroup exclusion), methodological disconcordance (parsimony vs modelbased), separate partition analyses (morphology vs molecules, codon positions, genes, etc), parametric simulation (incl. random outgroups), and split graphs are available relevant methods for the detection of LBA that should be used in combinations, because none alone is enough to stipulate LBA.</p>

The characteristics of the combined arms theory are to combine different weapon systems and weapon branches to conquer the enemy by attacking his weak spots. By combining weapon systems the commander in question will minimize his own weaknesses on the battlefield and therefore gain the upper hand on the enemy.  This theory gives a good theoretical view when analyzing which impact the Sea based operations- helicopters (SBO) have had during the specific decades that are being examined due to its ability to be applied on both land and naval forces. Literature on the combined arms theory as well as historical documents over these three decades constitutes the main sources which have been used to carry out the study. The result of the study shows that the implementing SBO-helicopters in the Swedish naval warfare tactics have had a major effect and more specifically in the AntiSubmarine Warfare (ASuW) area.

Upon consultation with NPS faculty, the School has determined that this thesis may be released to the public, its distribution is unlimited effective August 25, 2011. / One result of the break-up of the Soviet Union is that the DOD has been forced to reevaluate the roles of each of the Armed Services based on the declining resource pool. From the Marine Corps' evaluation of itself came the Combined Arms Regiment (CAR) concept. The objective of this study was to develop an estimate of the Life Cycle Cost (LCC) of the two possible vehicles used with the CAR and the CAR's components. Standard cost factors are used to cost out the various organizations involved. Two supporting analyses done in this study are: an evaluation of the Marine Corps' role in national security and how the CAR could be used to support that security role, and a comparison of the vehicle option operating characteristics which was done to enrich the dimensions under which the CAR could be evaluated. The results of the study are a tool which can help Marine Corps planners make more informed decisions in regards to the CAR concept. The final conclusion, based on the assumption that any CAR would act as a follow-on element of the MAGTF, was that although the CAR(LAV) was a workable option, the CAR using upgraded AAVs was the better, more cost effective option.

In the last decade, the EU-China partnership has become increasingly important, translating to the strategic issues of the twenty-first century, which include the problem of non-proliferation. As two of the world's visible international players, China and the EU both have a lot at stake in these matters. Non-proliferation also touches upon one of the bones of contention between the two : the EU embargo on arms sales to China. This paper examines the current state of cooperation on non-proliferation between the EU and China, and the impacts this cooperation may have, notably on the EU arms embargo.

Star and stellar cluster formation in spiral galaxies is one of the biggest questions of astrophysics. In this thesis, I study how star formation, and the formation of stellar clusters, proceeds using SPH simulations. These simulations model a region of 400 pc and 107 solar masses. Star formation is modelled through the use of sink particles which represent small groups of stars. Star formation occurs in high density regions, created by galactic spiral arm passage. The spiral shock compresses the gas and generates high density regions. Once these regions attain sufficiently high density, self-gravity becomes dominant and drives collapse and star formation. The regions fragment hierarchically, forming local small groups of stars. These fall together to form clusters, which grow through subsequent mergers and large scale gas infall. As the individual star formation occurs over large distances before forming a stellar cluster, this process can result in significant age spreads of 1-2 Myrs. One protocluster is found to fail to merge due to the large scale tidal forces from the nearby regions, and instead expands forming a dispersed population of young stars such as an OB association.
