“Everything has its Limits!” The Berlin Wall and the Problem of Desire
Get PDFBy the East German authorities’ account, the “Anti-Fascist Wall of Protection,” or Berlin Wall, was built to thwart hordes of anti-communist commandos poised to invade the socialist republic. If the Party acknowledged the stream of refugees from East to West at all, it was only to decry the efforts of paid agitators luring or coercing skilled East German workers over the border. These paranoid scenarios, I will argue, represented more than just hard-line propaganda and political expediency; they arose from fundamental assumptions about the psyche and society. Through an exploration of East German cultural responses to the construction of the Wall, my paper outlines the ideological fantasies of the individual and social body that precipitated this drastic measure
Modeling User Equilibrium in Microscopic Transportation Simulation
Get PDFUser equilibrium refers to the network-wide state where individual travelers cannot gain improvement by unilaterally changing their behaviors. The Wardropian Equilibrium has been the focus of a transportation equilibrium study. This paper modifies the dynamic traffic assignment method through utilizing the TRANSIMS system to reach the dynamic user equilibrium state in a microscopic model. The focus of research is developing three heuristics in a Routing-Microsimulation-Equilibrating order for reaching system-wide equilibrium while simultaneously minimizing the computing burden and execution. The heuristics are implemented to a TRANSIMS model to simulate a subarea of Houston, TX
An Analysis of a Strategic Transformation Plan: The Case of Alaska Airlines
Get PDFIn 2003, amid the turmoil of the U.S. airline industry in the post-9/11 environment, the senior management of the Alaska Air Group announced a “strategic vision” entitled “Alaska 2010.” The pronouncement articulated positions with regard to cost leadership, product differentiation, and growth. This study empirically assesses the efficacy of this decision with regard to the major network carrier of the air group, Alaska Airlines. The analysis focuses on the period beginning with the announcement and ending in 2010.The implementation of such a strategic protocol is dynamic and inter-temporal in nature. Therefore, it is often difficult to assess the effectiveness of changes in strategies, particularly since such effectiveness is often a function of the confounding forces of organizational strategy and market conditions. Thus, this study utilizes the multi-period methodology of the strategic variance analysis of operating income.This methodology decomposes operating income into three components: (1) growth, (2) price recovery, and (3) productivity. This is of particular interest from a strategic planning perspective, as the price component evaluates a company’s product differentiation strategy while the productivity component evaluates whether an airline’s low cost strategy was successful because of efficiency gains
Correlation Analysis of Duty Cycle Effects on Exhaust Emissions and Fuel Economy
Get PDFCorrelation analysis was performed to investigate the effects of drive cycle characteristics on distance-specific emissions (g/mile) and fuel economy (mpg) and consequently determine the most influential cycle metrics for modeling. A detailed analysis of linear and non-linear correlations was performed among cycle metrics to avoid collinearity and reduce the number of variables. The order of importance of the selected cycle metrics was determined. Results show that average speed with idle, number of stops per mile, percentage idle, and kinetic intensity were the most important cycle metrics affecting emissions and fuel economy. Preliminary regression analysis reinforced their importance for emissions modeling purposes
Beads from the Hudson's Bay Company's Principal Depot, York Factory, Manitoba, Canada
Get PDFThere is no other North American fur trade establishment whose longevity and historical significance can rival that of York Factory. Located in northern Manitoba, Canada, at the base of Hudson Bay, it was the Hudson's Bay Company's principal Bay-side trading post and depot for over 250 years. The existing site of York Factory is the last of a series of three posts, the first of which was erected in 1684. Completed in 1792, York Factory III functioned as the principal depot and administrative center for the great Northern Department until the 1860s when its importance began to wane. It then entered a long period of decline which ended in 1957, when the post was finally closed. Subsequent archaeological work at the site has revealed many structural features and associated artifacts including a large and varied assemblage of beads, mostly glass, which are the subject of this report
Spatial Transferability: Analysis of the Regional Automobile-Specific Household-Level Carbon Dioxide (CO2) Emissions Models
Get PDFThis paper compared performance of methods for combining model information estimated in one region and applied to another region to improve estimation results. The application is for models developed to estimate household-level automobile-specific CO2 emissions. The results indicated that automobile-specific CO2 emissions models can be transferred from one geographical region to another. The estimates of CO2 emissions can assist agencies such as policy makers, businesses, and transportation planners to track trends and identify opportunities to reduce CO2 emissions and increase efficiency of transportation systems to lessen their impact on global warming, climate change, and air quality standards
