    Creator:
    Skalland, Timothy Michael
    Abstract:
    Randomized trials are the gold standard for the clinical assessment of a new treatment compared to a placebo or standard of care. Often in clinical trials, patients are accrued sequentially rather than all at once. Thus, the data from such a trial becomes available sequentially to the researcher. Monitoring and...

  • Statistical methods for serially correlated zero-inflated proportions

    Creator:
    Sun, Luna
    Abstract:
    Proportion data falling in the continuum (0, 1) are very common in practice. It can also happen that an inflated number of zeros (or ones) occur with proportion data. There are extensive studies of zero-inflated data in the literature. Almost all of them, however, focus on zero-inflated count data. Furthermore,...

  • Influence of cultivar and maturity on blackberry polyphenolics and investigation of sediment formation in blackberry juice

    Creator:
    Siriwoharn, Thanyaporn
    Abstract:
    The influence of cultivar and maturity on polyphenolic composition and antioxidant activity was investigated by UV-Visible spectrophotometry and analytical high performance liquid chromatography (HPLC) in commercially important blackberry cultivars and selections. The anthocyanin pigments changed tremendously with ripening. Total anthocyanins increased from 74.7-317 mg/100g fw from underripe to over ripe...

    Abstract:
    Monilinia vaccinii-corymbosi pseudosclerotia overwinter on the soil surface and produce apothecia in early spring, providing primary inoculum for Mummy Berry Disease of blueberry. Burial under 2.5 cm of soil or the absence of light have previously been identified as critical factors preventing the development of apothecia. Mulches were applied to...

  • Ecology of female northern pintails during winter in the San Joaquin Valley, California

    Creator:
    Fleskes, Joseph P.
    Abstract:
    I radio-tagged 191 Hatch-Year (HY) and After-Hatch-Year (AHY) female northern pintails (Anas acuta) in the San Joaquin Valley (SJV), California and studied their movements, habitat use and survival during August March, 1991-94. Overall, 94.3% wintered in central California; the highest percentage left during the 1991 drought. Tulare Basin and Mendota...
