Chunking professional-technical programs to create pathways to degree completion in community colleges

Creator:: Dins, Kate
Abstract:: The purpose of this study was to explore the phenomenon of community colleges creating pathways to degree completion in professional-technical programs by breaking degree programs into smaller portions, referred to as "chunks." The purpose or possible advantage of chunking was that it would improve the rate of degree completion among...

Population demography, resource use, and movement in cooperatively breeding Micronesian Kingfishers

Creator:: Kesler, Dylan C.
Abstract:: Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species occur on islands, yet more than 90% of the avian extinctions witnessed during historic...

Advanced propulsion systems for linear motion with high performance requirements

Creator:: Zhou, Xiaolin
Abstract:: Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor,...

Dynamics of the Laurentide Ice Sheet

Creator:: Carlson, Anders Eskil
Abstract:: This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...

Grazing, nutrients, and marine benthic algae : insights into the drivers and protection of diversity

Creator:: Guerry, Anne D., 1973-
Abstract:: Two of the most powerful ways in which humans have altered ecosystems are by increasing productivity and changing the densities of important consumers. The bottom-up effects of productivity and the top-down effects of consumers have been identified as primary determinants of biological diversity, though the links between them remain unclear....

Comparative foraging ecology of five species of Pacific seabirds : multi-scale analyses of marine habitat use

Creator:: Suryan, Robert
Abstract:: Seabirds are an integral component of marine ecosystems, however, because humans typically observe only snapshots of their lives at sea, our understanding of seabird foraging ecology is often limited. A more complete understanding of the ecological roles of seabirds and identification of critical foraging habitats requires the ability to follow...

Secondary mathematics preservice teachers' development of technology pedagogical content knowledge in subject-specific, technology-integrated teacher preparation program

Creator:: Suharwoto, Gogot
Abstract:: The purpose of this study was to describe the development of mathematics preservice teachers’ technology pedagogical content knowledge (TPCK) in a subject specific, technology integrated teacher preparation program. The study also investigated the roles of several influential components of the program and the technology thread throughout the program in supporting...

Dynamic issues in applied microeconomics: market performance, market structure and advertising competition

Creator:: Iwasaki, Natsuko
Abstract:: This dissertation addresses issues of oligopoly markets where advertising plays a prominent role. The first study empirically investigates the effect of advertising regulations on equilibrium consumption of an addictive commodity using U.S. cigarette industry data. The results of the first study show that the advertising regulations reduced cigarette consumption by...

Model-based approximation methods for reinforcement learning

Creator:: Wang, Xin
Abstract:: The thesis focuses on model-based approximation methods for reinforcement learning with large scale applications such as combinatorial optimization problems. First, the thesis proposes two new model-based methods to stablize the value–function approximation for reinforcement learning. The first one is the BFBP algorithm, a batch-like reinforcement learning process which iterates between...

An analysis of technical efficiency and productivity growth in the Pacific Northwest sawmill industry

Creator:: Helvoigt, Ted L.
Abstract:: The objective of this project was to investigate technical efficiency and productivity growth in the Pacific Northwest sawmilling industry over the period 1968-2002. Productivity growth was decomposed into three components: technical change, efficiency change, and scale efficiency change. In addition, using econometric methods, changes in output elasticities and input substitution...
