A Post-Keynesian/Structuralist Strategy for Economic Development
Title from PDF of title page, viewed on April 1, 2014Dissertation advisor: L. Randall WrayVitaIncludes bibliographical references (pages 239-244)Thesis (Ph. D.)--Dept. of Economics
and the Social Science Consortium. University of Missouri--Kansas City, 2013There are two distinct traditions that have widely different views on the fundamental problem of economic development. This dissertation makes a contribution to the tradition known as the Scarcity in the Midst of Plenty Approach, which views the problem as an inability of less developed economies to fully utilize their existing resources because of demand constraints. The result of this situation is that these economies are frequently left with an inefficient production structure, high levels of structural underemployment, and few investment inducements that can ameliorate it. In order to solve this problem, the author argues that a development strategy must be implemented that is capable of combining short term demand targeting with long term structural change. Accordingly, the thesis of this dissertation is that the combination of balanced growth, employer of last resort, and the developmental state can serve as a development strategy that can successfully combine these two elements as well as minimize structural underemployment. Consequently, we argue that this strategy can initiate and/or sustain a development process in less developed economies. Our results demonstrate that this is indeed the caseAbstract -- Introduction -- The proper objective of an economic development strategy and some issues of terminology -- A post-Keynesian/structuralist strategy for economic development : the synthesis of balanced growth, employer of last resort, and the developmental state -- Financing our post-Keynesian/structuralist strategy for development -- Balanced growth -- Employer of last resort in less developed economies -- The developmental state and post-Keynesian/structuralist economics -- Conclusion -- Reference
Combined trellis coding and feedforward processing for MSS applications
The idea of using a multiple (more than two) symbol observation interval to improve error probability performance is applied to differential detection of trellis coded MPSK over a mobile satellite (fading) channel. Results are obtained via computer simulation. It is shown that only a slight increase (e.g., one symbol) in the length of the observation interval will provide a significant improvement in bit error probability performance both in AWGN and fading environments
A Novel Cable-Driven Robotic Training Improves Locomotor Function in Individuals Post-Stroke
A novel cable-driven robotic gait training system has been tested to improve the locomotor function in individuals post stroke. Seven subjects with chronic stroke were recruited to participate in this 6 weeks robot-assisted treadmill training paradigm. A controlled assistance force was applied to the paretic leg at the ankle through a cable-driven robotic system. The force was applied from late stance to mid-swing during treadmill training. Body weight support was provided as necessary to prevent knee buckling or toe drag. Subjects were trained 3 times a week for 6 weeks. Overground gait speed, 6 minute walking distance, and balance were evaluated at pre, post 6 weeks robotic training, and at 8 weeks follow up. Significant improvements in gait speed and 6 minute walking distance were obtained following robotic treadmill training through a cable-driven robotic system. Results from this study indicate that it is feasible to improve the locomotor function in individuals post stroke through a flexible cable-driven robot
The Growth of Black Holes and Bulges at the Cores of Cooling Flows
Central cluster galaxies (cDs) in cooling flows are growing rapidly through
gas accretion and star formation. At the same time, AGN outbursts fueled by
accretion onto supermassive black holes are generating X-ray cavity systems and
driving outflows that exceed those in powerful quasars. We show that the
resulting bulge and black hole growth follows a trend that is roughly
consistent with the slope of the local (Magorrian) relation between bulge and
black hole mass for nearby quiescent ellipticals. However, a large scatter
suggests that cD bulges and black holes do not always grow in lock-step. New
measurements made with XMM, Chandra, and FUSE of the condensation rates in
cooling flows are now approaching or are comparable to the star formation
rates, alleviating the need for an invisible sink of cold matter. We show that
the remaining radiation losses can be offset by AGN outbursts in more than half
of the systems in our sample, indicating that the level of cooling and star
formation is regulated by AGN feedback.Comment: 3 pages, 4 figures, to appear in the proceedings of "Heating vs.
