Hispanic Preschoolers' School Readiness: A Study Examining the Impact of Cultural, Social-Emotional, and Sociodemographic Factors
(2012-02-14)
The Hispanic population is becoming increasingly prevalent in the United States,
facing not only many sociodemographic risks, but academic risks as well. A large
number of Hispanics are entering school unprepared to learn. ...
Poor Talk: Surveying Social Science Discourse on Urban Poverty
(2012-10-19)
Understanding the dynamic relationship between culture and structure is a fundamental sociological question. Since the founding of the social sciences -- when Marx explored the connection between the 'macrostructure' and ...
The Conditional Effects of Female Descriptive Representation: A Study of Policy Influence in State Legislatures, 1983-2002
(2012-02-14)
Many scholars believe in order to have democratic legitimacy, females should be represented in governing bodies at all levels. Significant literature on female descriptive representation in the U.S. for women’s policy ...
The Application of Dynamic Nuclear Polarization Enhanced NMR to Non-Equilibrium Systems
(2012-02-14)
Nuclear magnetic resonance (NMR) yields remarkably detailed structural information about virtually any molecule. However, its application to non-equilibrium systems is hampered by a lack of sensitivity. To increase the ...
Regulation and Synchronization of the Master Circadian Clock by Purinergic Signaling from Suprachiasmatic Nucleus Astrocytes
(2012-10-19)
Molecular, cellular, and physiological processes within an organism are set to occur at specific times throughout the day. The timing of these processes is under control of a biological clock. Nearly all organisms on Earth ...
Analytical Study on Adhesively Bonded Joints Using Peeling Test and Symmetric Composite Models Based on Bernoulli-Euler and Timoshenko Beam Theories for Elastic and Viscoelastic Materials
(2012-02-14)
Adhesively bonded joints have been investigated for several decades. In most analytical studies, the Bernoulli-Euler beam theory is employed to describe the behaviour of adherends. In the current work, three analytical ...
Determining Salt Tolerance Among Sunflower Genotypes
(2012-02-14)
Crop lands around the world are becoming more salt-affected due to natural processes and agricultural practices. Due to this increase of salinization, acquisition of saline tolerant germplasm for breeding purposes is ...
Mercury Contamination in Pelagic Fishes of the Gulf of Mexico
(2012-10-19)
Knowledge of mercury concentrations in fish is essential for human health protection. Mercury is a naturally occurring element that acts as a neurotoxin to humans and other species. The biologically available mercury form, ...
An Electrolytic Method to Form Zirconium Hydride Phases in Zirconium Alloys with Morphologies Similar to Hydrides Formed in Used Nuclear Fuel
(2012-10-19)
An electrolytic cell was designed, built, and tested with several proof-of-concept experiments in which Zircaloy material was charged with hydrogen in order to generate zirconium hydride formations. The Electrolytic Charging ...
Control of Wrist and Arm Movements of Varying Difficulties
(2012-02-14)
Three experiments compared wrist and arm performance in a cyclical Fitts’ target task. The purpose of Experiment I was to determine if movement kinematics differed for wrist/elbow flexion/extension movements to targets of ...
