Effects of a Movement-based Curriculum on the Motor and Cognitive Development of Preschool-aged Children

Physical activity has been shown to be positively associated with improved motor skill and cognitive development in young children. Intervention designs are often constructed without focus on interrelatedness of the development of motor and cognitive self-regulatory skills. Purpose: To investigate the impact of a movement-based curriculum designed to integrate both motor skill and cognitive development in preschool children. Methods: Preschool-aged children [n=34; intervention group (n=28); control group (n=6)] participated in the study. Locomotor and object control motor skills were assessed via the Test of Gross Motor Development – 3rd Edition. Cognitive self-regulation (attention, working memory, and inhibition) was assessed via the Early Years Toolbox. These assessments were completed at pre- and post-intervention time points. Perceived competence and enjoyment were assessed during the curriculum via adaptations of Harter’s Perceived Competence Scale for Children and the Physical Activity Enjoyment Scale. Multiple 2x2 repeated measures ANOVAs were run to determine the impact of the curriculum on motor skills (scaled scores) and cognitive self-regulation (accuracy and reaction time). Results: There were no differences between intervention and control groups from pre- to post-intervention for motor skill scores. There were differences in locomotor (F=4.5b, p=0.045) and object control scaled scores (F=13.1b, p=0.001) in the total group (intervention plus control groups) from pre-intervention (11.5±0.5 and 11±0.4, respectively) to post-intervention (12.3±0.4 and 12.2±0.5, respectively). There was a significant improvement in the intervention (3.1±2.4 to 4.1±2.5) compared to the control group (6.4±2.6 to 4.2±2.7) for visual working memory accuracy (F=5.15b, p=0.035). In the total group, there was a significant time effect only for the auditory working memory reaction time scores (9.5±1.1 to 7.1±0.7; F=5.9b, p=0.025). Child self-reported perceived competence and enjoyment were perceived as high throughout the program (2±2.6 out of 25, and 30.2±4.3 out of 35, respectively)]]. Conclusion: This study appears to provide preliminary evidence that supports further exploration into the dynamic and use of a jointly tailored motor and cognitive movement program

dissertationA minimal type of the even 2-adicWeil representation is described. The Hecke algebra of this type is isomorphic to the classical affine Hecke algebra of type Bn. In this way, the Weil representation of a metaplectic group corresponds to the trivial representation of an orthogonal group in the local Shimura correspondence

Letter from Aaron Wood to James B. Finley

Wood writes that he has inquired about the availability of bacon for the Wyandot Mission, and has found that it is unavailable. Hogs are dying by the dozens due to lack of corn. Perhaps there will be something to send next summer or fall, but Finley should not count on it. Abstract Number - 13https://digitalcommons.owu.edu/finley-letters/1012/thumbnail.jp

Fabrication and characterization of a plasmonic grating platform for enhanced fluorescence biosensor applications

Surface plasmon resonance (SPR) research has grown substantially over the past several years and led to many substantial discoveries in nanotechnology. SPR is a phenomenon where light can be coupled to the interface between a metal, such as gold or silver, and a dielectric material, such as air or glass, to form an oscillation in the electrons at the interface. While only a few hundred nanometers in size, the electromagnetic field formed by this oscillation can interact with nearby molecules, such as fluorophores. Fluorophores are a specific class of molecules that absorb specific wavelengths or colors of light and emit a longer wavelength color back. If a fluorophore interacts with SPR, the resulting emission of light will be much brighter than normal. One research field, in particular, fluorescence biosensors, could greatly benefit by incorporating SPR as it can increase the sensitivity several orders of magnitude. In this research project, the ridge-groove structures also known as gratings found in HDDVDs and Bluray discs were transferred to microscope slides or silicon wafers and coated in silver to convert them into plasmonic gratings or gratings that can generate SPR if illuminated with light at a specific angle. The plasmonic gratings were found to increase the fluorescence emission intensity by 100-200 times their normal intensity. The plasmonic gratings were then incorporated into a biosensor for the detection of cortisol, an important stress hormone, and found that the plasmonic gratings increased the sensitivity of the biosensor such that normal cortisol levels in saliva could now be detected. The plasmonic grating was also incorporated into a biosensor for the detection of single strand DNA with similar sensitivity enhancements. These plasmonic gratings represent a simple yet effective means of greatly enhancing the fluorescent emission, and ultimately sensitivity, of any fluorescence microscope or biosensor system in which it is incorporated
