Educational technology associations as change agents : A case study

Creator:: Stephenson, Christine (Christine Gale)
Abstract:: This research addressed the role of educational technology associations as change agents within education with particular emphasis on issues of advocacy and leadership. Using a poststructural feminist lens and the metaphor of interview and analysis as storytelling, it explored the perspectives of nineteen individuals belonging to a national level educational...

Design, construction, and characterization of a six-electrode, direct current, variable length plasma source for atomic emmission spectroscopy

Creator:: Shields, James Phillip
Abstract:: The variable length, six-electrode plasma source for atomic emission spectroscopy described here is operated from three compact, simple, and inexpensive direct current power supplies. The vertical arcs formed between the three electrode pairs completely entrain the sample and are typically operated at 40 V and 20 A. Three concentric quartz...

A profile of the commonalities and characteristics of contextual teaching as practiced in selected educational settings

Creator:: Shields, Sue B., 1948-
Abstract:: Contextual teaching is emerging as an important concept in education reform efforts. This field study attempts to clarify the concept of contextual teaching by defining and identifying characteristics found in the research literature, experienced teacher observations and practices, and students' views of contextual teaching. The foundation for this field study...

Revisiting Lōʻihi: Geochemistry of Kamaʻehuakanaloa Lavas Reveals Complexities in the Pre-Shield to Shield Transition and Hawaiian Mantle Plume Source

Creator:: Truong, Thi B.
Abstract:: Studies of Hawaiian volcanoes contribute valuable insights about Earth processes and mantle evolution, and are fundamental for understanding the construction of the largest volcanoes on terrestrial planets. The pre-shield stage exists in every Hawaiian volcano, but is usually blanketed by high volume tholeiitic lava flows during the main shield stage....

Weighted vest exercise improves functional ability in women over 75 years of age

Creator:: Protiva, Karen W.
Abstract:: The purpose of this study was to determine the effects of long-term weighted vest exercise on hip bone mass, functional ability and static balance in elderly women. This was a within subject exercise intervention study and included a 6-month control period. Twenty-three subjects (age 85 ± 6) were recruited and...

Techno-economic and Life-cycle Analyses of Glucosamine and Lipid Production from Marine Diatom Cyclotella sp.

Creator:: Xiang, Xuwen
Abstract:: Currently the production of biofuel from algae is not economically competitive with petroleum fuel. However, co-production of high-value products may be able to justify the cost of large-scale algae cultivation. The basic goal of this study is to develop a techno-economic analysis (TEA) and Life-cycle assessment (LCA) for the production...

Functional polymers and proteins at interfaces

Creator:: Schilke, Karl F.
Abstract:: Functional polymers and proteins at interfaces and surfaces are of fundamental importance for biomaterials, biocatalysis and microreactor applications. Candida antarctica lipase B immobilized on poly-DL-tryptophan tethers showed 30x higher specific activity in aqueous and non-aqueous media than the same enzyme adsorbed or covalently bound directly to the surface. An excess...

The growing skeleton : influence of lifestlye and the development of normative data using DXA

Creator:: Fuchs, Robyn K.
Abstract:: To examine the potential for exercise to build bone mass during growth, objectives of this dissertation included: 1) determine the effects of 7 months of jumping followed by 7 months of detraining on hip and spine bone mass in the prepubertal children; 2) determine variables that best predict bone mineral...

Specific loading protocols to promote bone mineral density in young women

Creator:: LaRiviere, Jane A.
Abstract:: Osteoporosis is characterized by low bone mineral density (BMD), bone fragility, and an increased risk of osteoporotic fracture. The disease is systemic in nature but potential solutions include exercises prescriptions that target the clinically relevant sites of osteoporosis (hip and spine) to improve bone mass. The aim of this dissertation...

The effects of high-impact exercise on bone mass in adolescent girls

Creator:: Witzke, Kara A.
Abstract:: We evaluated anthropometric and performance measures which best predict bone mineral density (BMD) in 54 adolescent girls (14.6±0.5y; 22.7±14.0 months past menarche). BMD for the whole body, femoral neck, greater trochanter, lumbar spine (L2-L4), and mid-femoral shaft was assessed using dual-energy x-ray absorptiometry (DXA) (Hologic QDR 1000/W). Whole body lean...
