This study was inspired by the desire to understand the experience of mental health clinicians coping with work related stress in treating traumatized children. In studying this experience, heuristic design and methodology was followed. The findings of this study are based on interviews of 3 Caucasian, female clinicians, a 49-year-old...
The phylogenetic diversity of two continental shelf picoplankton
communities was examined by analyzing SSU (16S) ribosomal RNA (rRNA)
genes amplified from environmental DNA with bacterial-specific primers and
the polymerase chain reaction (PCR). Picoplankton populations collected from
the pycnocline (10 m) over the eastern continental shelf of the United States
near...
Azaspiracid has generated an enormous amount of scientific interest in the fourteen years since its initial discovery. The structure contains a 6,5,6 bis-spiroketal, a [3.3.1] bicyclic ketal and a 6,5-spiroaminal linkage as key moieties. With 9 rings, 20 stereocenters and three alkenes, the azaspiracid immediately attracted the interest of the...
Lead zirconate titanate (PZT) is the dominant ferroelectric material in the market due to its excellent piezoelectric properties, relatively high Curie transition temperature (T[subscript C]), low cost, etc. However, because of emerging applications with requirements for high temperature (T[subscript C] > 400 °C) ferroelectrics, researchers are increasingly looking at alternative...
The purpose of this study was to determine if differences exist among NCAA
divisions I, II and III as well as between Athletic Directors and Primary Women Administrators
with regard to the perceived competencies and preparatory coursework required
of athletic administrators.
A mail survey utilizing a six point forced choice...
Deep foundations are necessary for the construction of many structures, such as bridges and buildings, located in areas unsuitable for shallow foundations. Owing to the inherent variability of soil and the complex changes that occur in the soil adjacent to deep foundations as they are installed, the ability to accurately...
Nutritional ecology of unhunted and sympatric populations of
Roosevelt elk, Cervus elaphus roosevelti, and Columbian black-tailed
deer, Odocoileus hemionus columbianus, was investigated in old-growth
forests of the Hoh Valley in Olympic National Park, Washington, from
September 1979 to November 1981. Seasonal diets of both cervids
generally were comprised of common...
Unknown questions remain concerning the health of migrant farm workers,
seasonal farm workers, and other rural poor people. The objectives of this study were to
determine the demographic profile of a sample from a Community and Migrant Health
Center; to determine the prevalence of disease in migrant farm workers, seasonal...
Cooperative behaviors in bacteria are increasingly appreciated for their relevance to microbial ecology and utility as model systems for social evolution. One example is the secretion of siderophores, a structurally diverse group of compounds that chelate extracellular iron. Siderophore production is considered cooperative because the benefits can be shared with...
