Are Strict Churches Really Stronger? A Study Of Strictness, Congregational Activity, And Growth In American Protestant Churches, Rebecca Ann Flynn
Graduate Theses, Dissertations, and Problem Reports (ETD)
The purpose of this study was to determine whether strict churches are more likely than others to experience growth and what role congregational activity might play in the relationship between strictness and growth. Using data from the Faith Communities Today (FACT) 2000 survey, I tested Dean Kelley's (1972) claim that strictness is an important factor in church growth and Laurence Iannaccone's (1992) assertion that strict churches grow because they reduce free-riding, or increase congregational activity. The results lend only limited support for the idea that strict churches are more likely than more lenient churches to experience growth and do not …

On The Mechanisms Underlying Neural Repression By E(Spl)M8 In Drosophila, Bhaskar Kahali
Graduate Theses, Dissertations, and Problem Reports (ETD)
Notch signaling is an evolutionary conserved pathway that mediates binary cell-fate specification throughout animal development. Through a process termed lateral inhibition, Notch signaling drives two equipotent cells to adopt distinct fates. Binary cell-fate determination has been exceptionally well studied during Drosophila neurogenesis, particularly, in eye and bristle development. In the eye, Notch mediates the selection of R8 photoreceptors from clusters of R8 precursors by antagonizing the activity of the proneural activator Atonal (Ato). In the bristle, Notch drives the selection of the sensory organ precursors (SOP's) from a group of equipotential cells that expressed the proneural activators encoded by the …

Prediction Of Shrinkage Of Concrete Containing Supplementary Cementitious Materials Using Microscale Characterizations And Composite Modeling, Arkamitra Kar
Graduate Theses, Dissertations, and Problem Reports (ETD)
The inclusions of Supplementary Cementitious Materials (SCM) from industrial by products, such as slag, fly ash and silica fume in normal concrete derive several benefits. The use of SCM as partial replacement of portland cement divert these SCM from landfills, reduces CO2 emissions, and produces highly durable concrete leading to development of sustainable and green construction materials. One of the primary aspects of durability is to correctly estimate and predict the shrinkage. Since inclusions of SCM modify the volume, composition, and microstructure of the calcium silicate hydrate (C-S-H) of normal concrete, there are limitations on available prediction equations for shrinkage …
