Exploring Factors Contributing To Current Versus Former Coaching Status Of Women Coaches: A Social Exchange Theory Perspective., Justine Vosloo

Graduate Theses, Dissertations, and Problem Reports (ETD)

The percentage of women coaches at the helm of women’s sports teams has dropped from 90% in 1972, to 42.6% in 2010 (Carpenter & Acosta, 2010). Previous research has found that women coaches experience discrimination (Greenhaus et al., 1990) social stigma, and homophobia (Griffin, 1998). Difficulties with work-life balance have been identified as a barrier to coaching. Mentoring has been positive for the development of career satisfaction, commitment and positive job attitudes (Ragins et al., 2000), however, the role of mentoring in retaining women coaches needs exploration. This study used social exchange theory to determine if perceived costs/benefits of coaching, …

Extracellular Matrix Mediated Cartilage Regeneration: A Novel Three-Dimensional In Vitro Microenvironment To Facilitate Cell Expansion And Chondrogenesis, Fan He

Graduate Theses, Dissertations, and Problem Reports (ETD)

Joint articular cartilage is vulnerable for degenerative disease after trauma due to the limited self-healing ability. Mesenchymal stem cells (MSCs) are considered a promising source for cartilage repair and regenerative medicine because of their excellent capacities of self-renewal and multipotent differentiation. Conventional in vitro expansion system, however, limits the utilization of MSCs for cartilage regeneration because in monolayer culture MSCs rapidly lose their self-renewal ability and differentiation potential. The lack of proper microenvironment in the current two-dimensional expansion system is attributed to the loss of self-renewal and multipotent differentiation in MSCs. Three-dimensional (3D) cell-deposited extracellular matrix (ECM) provides a novel …

Investigation Of Egr And Fuel Property Effects On Advanced Combustion Strategies Using In-Cylinder Combustion Analyses, Jason D. Ice Jan 2010

Investigation Of Egr And Fuel Property Effects On Advanced Combustion Strategies Using In-Cylinder Combustion Analyses, Jason D. Ice

Graduate Theses, Dissertations, and Problem Reports (ETD)

Advanced combustion has progressively become a topic of interest as government regulations have stringently reduced the allowable limits of engine-out emissions from internal combustion engines. Advanced combustion can typically be classified as homogeneous charge compression ignition (HCCI) or premixed charge compression ignition (PCCI). In HCCI combustion, a well mixed fuel and air solution is spontaneously combusted, thus providing a homogeneous burn throughout the combustion process. By having an evenly distributed, homogeneous burn, fuel economy is not only significantly increased, but both oxides of nitrogen (NO x) and particulate matter (PM) can drastically be reduced from that of conventional combustion. HCCI …

Analyzing The Role Of Ck2 And Pp2a In Drosophila Position Effect Variegation, Swati Banerjee Jan 2010

Analyzing The Role Of Ck2 And Pp2a In Drosophila Position Effect Variegation, Swati Banerjee

Graduate Theses, Dissertations, and Problem Reports (ETD)

The results of the investigation into the role of CK2 and PP2A in Drosophila position effect variegation (PEV) and chromatin modification are presented here. PEV is seen when a gene normally found in euchromatin is placed in close proximity to heterochromatin. The propensity of heterochromatin to spread down the chromosome often results in inactivation of the displaced gene by compaction into heterochromatin. The study presented here utilized two different PEV reporter genes for investigating the role of two posttranslational modifying enzymes, the kinase CK2 and the phosphatase PP2A in chromatin formation. The reporter genes used in this study encode for …

Imputation Methods For Dealing With Missing Scores In Biometric Fusion, Yaohui Ding

Graduate Theses, Dissertations, and Problem Reports (ETD)

Biometrics refers to the automatic recognition of individuals based on their physical or behavioral characteristics. Multimodal biometric systems, which consolidate multiple biometric characteristics of the same person, can overcome several practical problems that occur in single modality biometric systems. While fusion can be accomplished at various levels in a multimodal biometric system, score level fusion is commonly used as it offers a good trade-off between fusion complexity and data availability. However, missing scores affect the implementation of most biometric fusion rules. While there are several techniques for handling missing data, the imputation scheme, which replaces missing values with predicted values, …

Role Of Protein Kinase Ck2 And Phosphatase Pp2a In Notch-Mediated Lateral Inhibition, Anasua Bose

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Notch signaling pathway is highly conserved in vertebrates and invertebrates and regulates binary cell fate specifications in diverse developmental contexts. In a process termed lateral inhibition, Notch signaling restricts a particular cell fate to a single cell from a group of multi-potential cells. This mechanism ensures precision in cell fate assignations, which are vital for histogenesis and organogenesis. Studies during Drosophila neurogenesis, specifically development of the compound eye and the mechanosensory bristles, have provided the most detailed insights into the underlying mechanisms. During this process, Notch signaling results in the selection of single R8 photoreceptors or bristle sensory organ …
