  • Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

    Creator:
    Barlow, Dawn R.
    Abstract:
    The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

  • An Investigation of Student Cognitive Engagement in the STEM Classroom—A Compilation of Faculty and Student Perspectives

    Creator:
    Barlow, Allyson J.
    Abstract:
    Student engagement has been the focus of much engineering education research, in large part due to its ties to student learning. Widely considered to be a meta-construct, student engagement is often broken down into behavioral, emotional, and cognitive components. Reasons for ongoing research on student cognitive engagement are twofold: educators...

  • In their own words : divorced and widowed women, retirement, and friendships

    Creator:
    Barlow-Pieterick, Marilyn
    Abstract:
    Friends benefit both our psychological and our emotional well-being by increasing overall happiness, life satisfaction, and a positive sense of self among women. Often, however, friendships decrease in the later years. The purpose of this study is to learn more about divorced or widowed, retired women and their friendships, specifically,...

  • Driver Distraction from Unmanned Aerial Systems: Evidence, Policy, and Mitigation

    Creator:
    Barlow, Zachary W.
    Abstract:
    Unmanned aerial systems (UASs), more commonly known as drones, have recently achieved commercial success for many public and private applications. As with all emerging technologies, new safety concerns and conflicts with existing paradigms are likely to arise. Many potential applications of UASs will result in their operation near roadway infrastructure,...

  • Physiological effects of water stress on young corn plants

    Creator:
    Barlow, Edward William Ross
    Abstract:
    Laboratory experiments were used to investigate the mechanism of plant response to water stress by determining the sensitivity of leaf elongation, photosynthesis and transpiration in young corn plants to a decrease in leaf water potential. In initial experiments, 9 day old corn plants were grown at soil water potentials of...

  • Purification and elementary analysis of Streptomyces griseus phage

    Creator:
    South, Dorothy Jean
    Abstract:
    This investigation was undertaken to provide a chemical description of an actinophage for Streptomyces griseus, and to determine the base composition of the phage DNA moiety. It was believed of interest to learn whether the actinophage for the filamentous S. griseus host would be different in its chemical properties from...

  • Essential fatty acids in noctuid moths : their nutrition and metabolism

    Creator:
    Grau, Philip Alvin, 1941-
    Abstract:
    The polyunsaturated fatty acids (PUFA) are known to be required for larval growth and normal wing development in several species of Lepidoptera but most of the basic information necessary for a complete understanding of this nutritional phenomenon has not been gathered. This includes the role of each of the essential...

  • All in a DNA's work : conservation genetics and monitoring of the New Zealand endemic Maui's and Hector's dolphins

    Creator:
    Hamner, Rebecca Marie
    Abstract:
    The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...

  • Beached Bones: Exploring the Genetic Impact of Exploitation on the Diversity of Great Whales in the South Atlantic

    Creator:
    Sremba, Angela L.
    Abstract:
    Commercial whaling during the 20th century drastically reduced many populations of great whales in the Southern Hemisphere. The Antarctic blue whale, for example, is estimated to have been reduced to less than 0.1% of its original abundance based on catch records and population dynamic models. Despite this population bottleneck, several...

  • Low-voltage data converters

    Creator:
    Meng, Qingdong
    Abstract:
    With the growing demand for portable/consumer electronics, such as digital audio/video (AV), the downscaling of device dimensions, which enables the integration of an increasing number of transistors in a single chip, is mandatory. This trend also continuously pushes the power supply voltage down to reduce the power consumption and improve...
