  • Zooplankton of the Galapagos Islands

    Creator:
    Figueroa, Diego
    Abstract:
    The marine climate of the Galapagos is spatially and seasonally heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has never been done. This study is an initial effort to establish the distribution and community structure of zooplankton in the Archipelago. I collected zooplankton samples by vertical tows over the Galapagos...

  • Zinc tin oxide thin-film transistor current mirror circuits

    Creator:
    Feller, Layannah Elizabeth
    Abstract:
    The central focus of this thesis is the design, fabrication and characterization of amorphous oxide semiconductor (AOS) thin-film transistor (TFT) current mirrors. The thin-film deposition and circuit fabrication methods used to realize zinc tin oxide (ZTO) TFT current mirrors are addressed in order to elucidate the processing challenges for this...

  • Zinc tin oxide thin-film transistor circuits

    Creator:
    Heineck, Daniel Philip
    Abstract:
    The primary objective of this thesis is to develop a process for fabricating integrated circuits based on thin-film transistors (TFTs) using zinc tin oxide (ZTO) as the channel layer. ZTO, in contrast to indium- or gallium-based amorphous oxide semiconductors (AOS), is perceived to be a more commercially viable AOS choice...

  • Zinc Tin Oxide Thin Films by Pulsed Laser Deposition for use in Transparent Thin-Film Transistors

    Creator:
    Osborne, James J.
    Abstract:
    Zinc tin oxide (ZTO) films deposited by pulsed laser deposition (PLD) are investigated as a channel layers for transparent thin-film transistors (TTFTs). Films are deposited on glass for characterization, and transistor channel layers are deposited onto aluminum oxide-titanium oxide/tin doped indium oxide/glass substrates (ATO/ITO/glass) to produce TTFTs. UV-visible spectroscopy on...

  • Zimbabwean counselors' knowledge of and attitudes toward HIV/AIDS

    Creator:
    Richards, Kimberly A.
    Abstract:
    Acquired Immune Deficiency Syndrome (AIDS) has become the world's foremost health threat and is the number one killer in Zimbabwe. Acquired Immune Deficiency Syndrome impacts not only the individual who has AIDS, but on nuclear and extended families, and all aspects of society in Zimbabwe. Since studies have indicated that...

  • Zeros of Replicable Functions

    Creator:
    Toomey, Benjamin J.
    Abstract:
    Following the work of Asai, Kaneko, and Ninomiya for Faber polynomials associated to the modular group, and Bannai, Kojima, and Miezaki's partial proof for the case of the Fricke group of level 2, we show that the zeros of certain modular functions for some low-level genus zero groups associated to...

  • Zero kinetic energy photoelectron spectroscopy of polycyclic aromatic hydrocarbons

    Creator:
    Zhang, Jie
    Abstract:
    In this dissertation, I present electronic spectra of a few polycyclic aromatic hydrocarbons (PAHs): tetracene, pentacene, pyrene, benzo[g,h,i]perylene and benzo[a]pyrene using resonantly enhanced multiphoton ionization (REMPI) and zero kinetic energy (ZEKE) photoelectron spectroscopy. The work of tetracene and pentacene also combine a laser desorption source with a ZEKE spectrometer, demonstrating...

  • Youth-Caseworker Relationships and Academic Resilience of Youth in Foster Care

    Creator:
    Jaramillo, Jamie
    Abstract:
    Academic success is a salient domain of youth development and is related to positive lifelong outcomes among youth in foster care. However, youth in foster care experience compounding adversities, including maltreatment and foster care placement itself, which put them at risk of academic disengagement and underachievement. Despite these adversities, academic...

  • Youth Wellbeing During the First School Year of the Covid-19 Pandemic: An Intersectional Analysis

    Creator:
    Fenske, Linda J.
    Abstract:
    During the first full school year of the Covid-19 pandemic, two central contexts for adolescent development—home and school—changed utterly. In Oregon, most middle- and high schoolers attended school entirely remotely from the beginning of the pandemic, in March, 2020, through the end of April, 2021, removing both the supports available...

  • Young Adults’ Personal Goal Appraisals over the Great Recession Years : A Case Study of Germany

    Creator:
    Recksiedler, Claudia
    Abstract:
    In 2008, the “Great Recession” gained its momentum and quickly grew into a global crisis that led to massive gross domestic product declines and job losses in countries around the world. Relative to prior economic downturns, young adults were greatly affected by the Great Recession. This likely placed a premium...
