Reconstructing Neogene Vegetation and Climates to Infer Tectonic Uplift in Western Yunnan, China

Sun, Bai Nian, Wu, Jing Yu, Liu, YuSheng Christopher, Ding, Su Ting, Li, Xiang Chuan, Xie, San Ping, Yan, De Fei, Lin, Zhi Cheng 01 May 2011 (has links)
Neogene climates and vegetation history of western Yunnan are reconstructed on the basis of known fossil plants using the Coexistence Approach (CA) and Leaf Margin Analysis (LMA). Four Neogene leaf floras from Tengchong, Jianchuan and Eryuan in southwestern China are analyzed by the CA, and the paleoclimatic data of one Miocene carpoflora from Longling and three Pliocene palynofloras from Longling, Yangyi and Eryuan are used for comparison. The Miocene vegetation of the whole of West Yunnan is subtropical evergreen broad-leaved forest, and a similar mean annual precipitation is inferred for Tengchong, Longling and Jianchuan. However, by the Late Pliocene a large difference in vegetation occurred between the two slopes of Gaoligong Mountain, western Yunnan. The region of Tengchong retained a subtropical evergreen broad-leaved forest vegetation, whereas in Yangyi and Eryuan a vertical vegetation zonation had developed, which consists, in ascending order, of humid evergreen broad-leaved, needle and broad-leaved mixed evergreen, and coniferous forests. Distinctively, the Late Pliocene vegetational patterns of West Yunnan were already very similar to those of the present, and the Pliocene mean annual precipitation in Tengchong was markedly higher than that of Yangyi and Eryuan. Considering that the overall vegetation of West Yunnan and the precipitation at Yangyi and Eryuan have undergone no distinct change since the Late Pliocene, we conclude that the Hengduan Mountains on the northern boundary of West Yunnan must have arisen after the Miocene and approached their highest elevation before the Late Pliocene. Furthermore, the fact of the eastern portion of the Tibetan Plateau underwent a slight uplift after the Late Pliocene is also supported.

A Re-examination of the Early Pueblo I Components at Monument Village, 42SA971

Pollock, Rachel K. 13 December 2011 (has links) (PDF)
The Pueblo I period (A.D. 750-900) was a time of widespread change in population and settlement organization in the Northern San Juan region of the American Southwest. One major distinguishing feature of the Pueblo I period is the rapid appearance of villages in the late A.D. 700s. Monument Village in southeastern Utah was excavated by Brigham Young University in the late 1960s and early 1970s, but has never been adequately described. Monument Village has a substantial early Pueblo I occupation but the dating of various structures and the size of the overall settlement are unclear. This thesis re-examines architectural and ceramic data from Monument Village and compares Monument Village to better documented early Pueblo I Villages in the Northern San Juan region. Monument Village does appear to have been a small village comparable to other villages that formed in the early Pueblo I period.

La Vida en el Norte [Life in the North], Three Mexican Women in the Roanoke Valley

Uribe Leon, Marcela 18 April 2006 (has links)
The purpose of this work was to investigate how identity is transformed by the experience of immigration. Two research questions were conceptualized in order to address the essence of the inquiry. How do Mexican immigrant women living in the Roanoke Valley describe their lives back in Mexico? How do Mexican immigrant women living in the Roanoke Valley describe their lives in the United States? Interviews with three first-generation Mexican female immigrants currently living in Southwest Virginia formed the basis of the qualitative study presented in this work. The study was designed to understand Mexican women immigrants through their personal experiences and stories. The two main findings about their perceptions of life back in Mexico were related to lack of economic resources and the limited opportunities they had. Also, their memories of Mexico were paired with nostalgia of their loss in terms of family relations and cultural understanding. In general, the participants perceived themselves to be in a better economic position that encourages them to stay in the United States. An unexpected finding was that in all three cases domestic violence was a constant in the women's lives. However, despite the gender construction of Mexican women as passive females, the commonality in the three cases was that they looked for alternatives on how to resist violence by seeking support and resources to escape from it on either side of the border. / Master of Arts

A study of the natural acidity of milk in southwest Virginia

Hatcher, Dock A. January 1942 (has links)
Recently interest has been aroused over the topic of acidity of milk in southwest Virginia. Certain manufacturers of skin milk powder have manufactured products, which upon being reconstituted have exceeded the government limits in titratable acidity to be classified as "Extra Grade." This is the highest grade and cannot exceed 0.15 per cent in titratable acidity. Normal milk when freshly drawn, will naturally be slightly acid in reaction. This acidity of milk has been shown by various workers to be due to the presence of natural constituents such as the phosphates, proteins, carbon dioxide, and citrates. Any increase in acidity upon standing is due to the action of fermenting bacteria, changing lactose to lactic acid. It has been proven that normal milk with a high natural acidity is not objectionable in the manufacture of dairy products. However a highly-developed acidity is undesirable and may cause serious economic losses if used to any great extent. It is the opinion of certain dairymen and dairy manufacturers in this locality that due possibly to some natural existing condition in this area (such as soil type), the fresh milk may have a higher natural acidity than milk produced in other sections of the country. Should this be the case, it would seem logical that the standards should be modified so as not to reject that milk exceeding 0.15 percent titratable acidity, if the acidity is entirely natural. The nature of this problem is to attempt to find out if the milk produced in this area has a higher natural acidity than is expected; and if so, what the factors are contributing to it. / Master of Science

House Legends and Perceptions of the Civil War: a Multiple Case Study on the Civil War Legends Told About Antebellum Homes in the New River Valley, Roanoke Valley, and Nearby Counties of Virginia

Dale, Margaret Elizabeth 12 June 2003 (has links)
This study was designed to identify recurring themes in Civil War legends that are told in reference to antebellum homes in regions of Southwest Virginia. Existing literature indicates that collecting these legends is an important task because doing so helps others to better understand the community of legend-tellers. Previous research has also indicated that legends form a type of American mythology with reveals the way the legend-tellers perceive the specific subject they describe in the legends. Eight historic homes were visited in six southwestern counties of Virginia. Qualitative data were collected from a purposive sample of 12 participants who lived in these houses, previously lived in an historic house, or worked in an historic house museum. Each house was chosen as a site of inquiry because it has some significance for those interested in the Civil War or because it represents typical houses in similar southwestern Virginian communities during the Civil War era. In-depth interviews were the sole means of data collection and provided detailed and unlimited legends used to identify themes. The data were collected analyzed using a multiple case study approach. The findings from this study indicate that Civil War legends are being told in reference to antebellum homes in Southwest Virginia. Additionally, the tellers of the legends have common thoughts about the Civil War. The three major conclusions made in this study are (1) northern soldiers were aggressors during the Civil War; (2) southerners were strong during the Civil War; and (3) ghosts and ghostly activity serve as reminders of the Civil War. By continuing to share these legends, the tellers indicate their own perspectives of the Civil War as well as the perspectives of those who originate the legends. The legend-tellers also provide insight into the culture of today's southwestern Virginians as well as the Civil War era southwestern Virginians. / Master of Science
