In the past few decades, wildfires have increased in size and severity in the Southwest and across the western US. These recent trends in fire behavior are a drastic change in arid, ponderosa pine and mixed conifer forests of the Southwest compared with tree-ring records of fire history for the past ~ 400 years. This study presents a late Holocene record (~ 3,000 years) of fire history and related changes in fire regimes with climate variability over annual to multi-decadal time scales. Tree-ring and alluvial-sediment sampling sites were paired in four small, tributary basins located in the western San Juan Mountains of Colorado. In our study sites, tree-ring records show that fire return intervals were longer and fire behavior was more severe on the north-facing slopes with relatively dense mixed conifer stands. Increased fire barriers and steep topography decreased the fire frequency and extent relative to gentle terrain elsewhere in the range and leading to a lack of synchrony among fire years in different parts of the study area. The alluvial-sediment record showed four peaks in high-severity fire activity over the past 3,000 years ranging between 200 - 400 years in length. The timing of peaks coincided with decadal-length drought episodes and were often preceded by multiple decades of above average winter precipitation. The sampling of alluvial-sediment and tree-ring data allowed for site-level comparisons between recent alluvial deposits and specific fire years interpreted from the tree-ring records. We found good correspondence between the type of fire-related sediment deposit (i.e. geomorphic response) in the alluvial record and the extent of mixed and high-severity fire estimated from the tree-ring record, and the correspondence was well-supported by the debris flow probability model results. The two paleofire data tend to represent particular components of the historical fire regime, with alluvial-sediments biased towards infrequent, high-severity events during recent millennia, and the tree-ring record biased toward lower severity fires during recent centuries. The combined analyses of different paleofire proxy types in the same study sites, therefore, can enhance and expand our understanding of fire and climate history beyond what is possible with either proxy alone.

Historical events are framed by the actors of the time and then re-framed by subsequent historians and the public. This thesis examines the historiography of the San Juan Island Dispute, 1853-1871, known colloquially in the twentieth century as the “Pig War.” In 1859, after an American settler on San Juan shot a pig owned by the Hudson’s Bay Company, the American military and the British Royal Navy met in a tense stand-off resulting in a twelve year joint-military occupation of the island. This conflict was the last border dispute between the two nations. Following World War II, a message of peace became the dominant trope of histories written about the “Pig War.” The term itself has come to represent this overarching theme. With documents from the dispute, such as colonial despatches, official correspondence and newspaper editorials, this thesis considers how the event was framed at the time; and employing semiotics as a technique for discourse analysis, it examines how the “war” was re-framed in the twentieth century. The thesis follows Alfred Young’s research on antebellum America’s commemoration of the “Boston Tea Party,” with its message appropriated by politicians, merging history and myth. The “Pig War” occupies similar terrain as the reconceptualization of the event embodies its own message of a unique identity for the Pacific Northwest, associated with the 49th parallel as the world’s longest, most peaceful, “undefended” border. / Graduate / 2015-04-26 / 0578 / 0334 / 0337 / lyallg@uvic.ca

Dar a conocer la importancia de difundir las diferentes danzas peruanas, debido a que muchas de ellas son consideradas patrimonio cultural de la nación. Comprende una investigación sobre el desarrollo de la danza. Se estudió diferentes terrenos con el fin de elegir el más adecuado, luego se analizaron diferentes puntos importantes de este con el objetivo de tener claro diversos conceptos que nos ayuden en el diseño a realizar pata la Escuela. Los aspectos tecnológicos que analizaron fueron con el fin de tener en cuenta el sistema constructivo, la modulación, materiales y cerramiento que se utilizará en el proyecto. / Make known the importance of spreading the different Peruvian dances, because many of them are considered cultural heritage of the nation. It includes an investigation about the development of dance. Different fields were studied in order to choose the most suitable, then different important points of this were analyzed in order to have clear concepts that help us in the design to be done for the School. The technological aspects that were analyzed were in order to take into account the construction system, the modulation, materials and enclosure that will be used in the project. / Tesis
