1980-2000年中国LUCC对气候变化的响应

基于中国1980-2000年气候数据及两期土地利用／土地覆盖(LUCC)数据,利用Holdridge���被生态分区模型、重心模型及土地利用程度模型,分析气候变化及人类活动对中国植被覆盖及土地利用的影响程度及变化趋势。1980-2000年间,中国大部分地区温度升高,降水增多。气候变化不仅影响了中国植被群落分区,更进一步影响了植被群落的生长状况;东北、华北、内蒙古高原等区域未利用土地型向草地和灌木生态类型转换,草地和灌木型生态类型向林地和耕地型转换;又因为1980-2000年间中国经济的发展,东部沿海区域城市乡村建设用地及交通用地的增多,使土地利用类型南农业耕地型向建设用地型发展,导致土地利用程度指数的升高。气候变化及经济发展的双重作用,导致中国土地利用程度重心20年来向东北方向移动了54km,东西方向土地利用程度偏移强度,气候占81％,人类活动占19％,南北方向土地利用程度偏移强度,气候占85％,人类活动占15％。

A preliminary genetic map of Zhikong scallop (Chlamys farreri Jones et Preston 1904)

Zhikong scallop (Chlamys farreri Jones et Preston 1904) is one of the most important aquaculture species in China. The development of a genetic linkage map would provide a powerful tool for the genetic improvement of this species. Amplified fragment length polymorphism (AFLP) is a PCR-based technique that has proven to be powerful in genome fingerprinting and mapping, and population analysis. Genetic maps of C. farreri were constructed using AFLP markers and a full-sib family with 60 progeny. A total of 503 segregating AFLP markers were obtained, with 472 following the Mendelian segregation ratio of 1:1 and 31 markers showing significant (P< 0.05) segregation distortion. The male map contained 166 informative AFLP markers in 23 linkage groups covering 2468 cM. The average distance between markers was 14.9 cM. The female genetic map consisted of 198 markers in 25 linkage groups spanning 3130 cM with an average inter-marker spacing of 15.8 cM. DNA polymorphisms that segregated in a 3:1 ratio as well as the AFLP markers that were heterozygous in both parents were included to construct combined linkage genetic map. Five shared linkage groups, ranging from 61.1 to 162.5 cM, were identified between the male and female maps, covering 431 cM. Amplified fragment length polymorphism markers appeared to be evenly distributed within the linkage groups. Although preliminary, these maps provide a starting point for the mapping of the functional genes and quantitative trait loci in C. farreri.

Analiza struktury przestrzennej i czasoprzestrzennej maksymalnych opadów dobowych w Polsce w latach 1956-1980

Jednym z wyników prognoz wykonywanych z zastosowaniem globalnych i regionalnych modeli klimatycznych jest odkrycie wysokiego prawdopodobie��stwa wzrostu częstości oraz natężenia ekstremalnych opadów. Poznanie prawidłowości ich powtarzalności i zasięgu przestrzennego ma oczywiście bardzo duże znaczenie gospodarcze i społeczne. Dlatego, niezale��nie od wprowadzania nowych technik pomiarowych nale��y dokonywać analizy i reinterpretacji archiwalnych danych, korzystając z możliwości stwarzanych przez rozwój GIS. Głównym celem opracowania jest analiza prawidłowości przestrzennej i czasowej zmienności miesięcznych oraz rocznych maksymalnych dobowych sum opadów (MSDO) z lat 1956-1980, z obszaru Polski. W pracy wykorzystano nowe w geografii polskiej metody geostatystyczne. Do publikacji dołączono dysk DVD ze źródłową bazą danych i najważniejszymi wynikami w postaci numerycznej i kartograficznej.

Azione destabilizzante e impegno politico. Le figure femminili tra il giallo e il nero Italiani dal 1980 a oggi

My thesis analyses female figures in Italian crime fiction since 1980, from narratological, sociological and gender-studies perspectives. It considers the narrative structure of the giallo and the noir, taking into account the difficulties, particularly in Italy, of establishing what noir fiction is and if/how it is possible to frame it in a specific narrative scheme. This discourse connects to the extraordinary success of Italian giallo and noir fiction over the past fifteen-twenty years. In this scenario, I examine the place of female writers in relation to this phenomenon, especially since the 1980s: in terms of the level of visibility/acceptance of their work, in a narrative space traditionally considered as a male territory, and with regard to their writings, which introduce different narrative perspectives. Specifically, I consider selected texts by leading female Italian writers, in which female elements (writers/characters) become destabilizing factor both on the narrative level, by undermining the schemes of ‘formulaic’ fiction, and on the political one, through their implicit potential (as women) for disrupting the rigid models inherited from processes of social conditioning and from political structures. In terms of gender identities, such texts offer scope to question conventional social constructions of the subject: by empowering the female narrative voice and by embodying it in characters (investigators/killers) traditionally personified by male figures. These texts offer themselves as a critical space where, potentially, readers can rethink static gendered relationships and stereotypical symbolical categories.

Final Archaeological Investigations at the Maynard-Burgess House (18AP64): An 1850-1980 African-American Household in Annapolis, Maryland

The Maynard-Burgess House was excavated by Archaeology in Annapolis from Fall, 1990 to Summer, 1992. The still-standing house is located at 163 Duke of Gloucester Street in Annapolis' Historic District and is today being restored by Port of Annapolis, Incorporated. Archaeological testing and excavation of the site was developed alongside architectural analyses and archival research as the initial phase of the home's restoration. The Maynard-Burgess House was continuously occupied by two African-American families, the Maynards and the Burgesses, from the 1850s until the late 1980s. The main block of the house was built between 1850 and 1858 by the household of John T. Maynard, a free African American born in 1810,and his wife Maria Spencer Maynard. Maynard descendants lived in the home until it was foreclosed in 1908 and subsequently sold to the family of Willis and Mary Burgess in 1915. Willis had been a boarder in the home in 1880, and his sister Martha Ready had married John and Maria's son John Henry. Burgess descendants lived at the home until its sale in 1990.

SAXOPHONE SONATAS 1980-2010

The purpose of this dissertation project identifies contemporary solo saxophone literature, specifically sonatas between the years 1980 and 2010. The overwhelming majority of repertoire written during these thirty years consisted primarily of either multi-movement or through-composed character pieces. By limiting the selected repertoire to sonatas one can still investigate the breadth of the literature that has helped validate the saxophone in the realm of classical music in a format that has seemingly fallen out of favor with composers. The saxophone had developed a unique voice by the middle of the twentieth century in both Europe and in the United States. European composers such as Claude Debussy, Florent Schmidt, Jacques Ibert, Darius Milhaud, Alexander Glazounov, Erwin Schulhoff and Bernard Heiden recognized the potential and beauty of the instrument, while the saxophone had found quite a different niche in vaudeville, jazz, and military bands in the United States. If not for the dynamic performances by concert saxophonist such as Marcel Mule, Sigurd Rascher, Jean-Marie Londeix, Daniel Deffayet, Cecil Lesson, Larry Teal, Eugene Rousseau, Fredrick Hemke and Donald Sinta, the timbral possibilities and technical virtuosity of the saxophone would not have been discovered. The awe inspiring performances by these soloists led to the commissioning of a multitude of works by composers looking to expand the sonic possibilities of this relatively new instrument. Through the 1970's American composers such as Leslie Bassett, Paul Creston, Henry Brant, Robert Muczynski, and Karel Husa were writing significant works for the saxophone, while European composers such as IngolfDahl, Edison Denisov, Alfred Desenclos, Henri Tomasi and Marius Constant were each making their own contributions, all leading to a significant quantity of repertoire that met the quality demands set by the performers. The compositions chosen for this dissertation project were selected after numerous performance, pragmatic, programming and pedagogical considerations were taken into account. The three recitals occurred on: March 7, 2010, December 10, 2010 and May 1, 2011 in either the Gildenhorn Recital Hall or Lecture Hall 2100.

Inundaciones y su relación con el clima y la hidrología subterránea en el Noroeste de Buenos Aires (1980-2010) : aplicación de percepción remota

Gran parte de la llanura pampeana Argentina presenta una escasa red de drenaje superficial y niveles fre��ticos cercanos a la superficie que, junto a los excesos hídricos, producen a menudo inundaciones provocando un fuerte impacto sobre los ecosistemas naturales y modificados. En esta tesis, mediante la utilización de sensores remotos, caractericé el área inundada y su relación con condicionantes climáticos, hidrológicos y de uso de la tierra para el período 1980-2010 en una superficie de 24.000 km2 en el noroeste de la provincia de Buenos Aires. La estimación de la fracción del área inundada mediante una clasificación con umbral en la banda 5 de imágenes Landsat presentó alta confiabilidad cuando se la comparó con un método más complejo de clasificación preexistente (r2=0,99, EEest = 1 por ciento, n = 10). Se observaron fuertes oscilaciones de la superficie inundada lo largo del período de estudio con valores extremos de 0,96 y 27,7 por ciento. Se identificaron claramente dos grandes ciclos completos de inundación en 1987 y 2001, los que llegaron a cubrir el 22,5 y 27,7 por ciento del territorio respectivamente y retrayéndose a niveles menor a 5 por ciento en los siguientes dos años en ambos episodios. La utilización del producto MOD13Q1 del sensor MODIS para estimar el área inundada empleando la técnica de Análisis Lineal de Mezclas Espectrales presentó altos niveles de error cuando se lo comparó con las estimaciones realizadas con Landsat. El análisis que vinculó al área inundada con la precipitación (PPT), el nivel fre��tico absoluto y sus variaciones, la evapotranspiración potencial (ETP) y el balance hídrico, mostró que la precipitación fue el factor que más estuvo asociado a los eventos de inundación aún con períodos largos de integración de 24 y 36 meses. La inclusión de la evapotranspiración en el análisis, tanto en forma directa como a través del balance PPT-ETP, no mejoró en forma apreciable la explicación de las inundaciones. El nivel fre��tico absoluto mostró una asociación alta con el área inundada (mayor inundación con niveles más superficiales) a la escala de 3 meses, perdiendo peso como variable explicativa en períodos más extensos. Ante la posibilidad de que se desarrollen nuevos eventos de inundación masiva en la llanura pampeana es trascendental avanzar en el conocimiento de las interacciones entre la hidrología, el clima y el uso del suelo a fin de compatibilizar estrategias agrícolas con estrategias de ordenamiento hidrológico del territorio para reducir el impacto de dichos eventos
