A Spatial Comparison of Short and Long Term Migration Trends in China

China’s floating population, those individuals who have migrated between counties or provinces for a period of longer than 6 months, account for 79 million individuals. If intracounty migration is also included, the number jumps to 145 million individuals or over 11% of the total population. This study examines the geographical differences in short and long term migration using ArcGIS to manipulate the spatial GIS data. The study shows that both short and long term migration (in absolute numbers) occurs more frequently near cities and in coastal regions. However, by normalizing the data by population size, the study eliminates the problems of population size on the size of the migrants. Using this normalized data, the study finds that western and northern counties have a large number of migrants present relative to the size of the population. Determining where this floating population migrates helps explain regional inequalities in employment opportunities.

Carl Maria von Weber’s Overture to Oberon: A History of Recorded Performance

My research examines the recorded performance history of the Overture to Weber’s Oberon in light of these aesthetic goals. I have charted changes in performance practice trends, including in timing, tempo fluctuation, rhythmic accuracy and ensemble, and the use of portamento. The twenty recordings studied that I surveyed span nearly seventy-five years, and include many of the 20th century’s most prominent conductors and orchestras, including groups from Communist Russia, both pre-World War II and post-World War II continental Europe, the British Isles, and the United States.8 Though by no means comprehensive, my selections encompass a diverse sampling of surviving recordings, ensuring a large enough sample size to reflect general trends in the performance of Weber’s masterpiece. My research and analysis confirms the conventional view of a move toward more accurate—but also more cautious, uniform, and inexpressive— performances. Surprisingly, however, this analysis also suggests that we are on the cusp of a new era in orchestra performance practice, one that shares many of the values of the earlier recorded performances. While maintaining today’s high standards of execution, modern performances now look to regain many of the past’s expressive qualities, doing so in sometimes surprising ways.
