Introduction: The primary task of physical educators is to teach motor skills to beginners, and motor learning studies continually strive to find better ways to optimize the skill acquisition process. In line with this, our study aims to evaluate and compare the effectiveness of two learning methods, analogy learning and explicit learning, in promoting children's acquisition of novel motor skills. We specifically focus on skills that differ biomechanically and kinematically from skills learned through explicit instructions, and we also investigate how the physical form of the skill evolves with practice. Material and Methods: Forty-five right-handed healthy beginner male students (mean …

The Use Of Grasslands To Improve Water Quality In The New York City Watershed, D J. Flaherty, J Drelich Jr

IGC Proceedings (1977-2023)

The purpose of this paper is to demonstrate how grasslands are used in the New York City (NYC) Watershed to improve water quality. A Watershed Agricultural Program was established to voluntarily implement Pollution Prevention Best Management Practices on watershed farms. Grasslands have been used in Whole Farm Plans to reduce nutrients, sediments and other toxic materials reaching New York City’s water supply. Rotational grazing has been used to limit access to streams and stream banks and improve nutrient distribution on pastures. Improved grassland management also helps correct the nutrient balance on the farm and facilitates better nutrient management. Brush removal …

Policy Options For Decreasing N And P2o5 Losses From Grassland Based Dairy Farms, P.B M. Berentsen, G.W J. Giesen

IGC Proceedings (1977-2023)

Policy instruments for reducing nutrient losses include extension and education, research, financial incentives such as subsidies and levies, and regulations. The potential of these instruments for reducing nitrogen (N), phosphate (P2O5), and ammonia (NH3) losses is examined for Dutch specialized dairy farms on sandy soils. A linear programming model is used to estimate policy impacts. Results indicate that efficiency improvements through extension, education, and research alone have the potential to decrease total N losses to government target levels in 2005 and to erase 92% of the gap between base and target P2O5 losses, but only 24% of the corresponding NH3 …

Benefits Of Coding In The Elementary Classroom, Samantha Panek

Assessing The Effects Of Repetitive Mild Traumatic Brain Injury On Risk/Reward Decision Making And Catecholamine Associated Proteins, Christopher Knapp

Theses and Dissertations

Mild traumatic brain injury (mTBI) disrupts cognitive processes that influence risk taking behavior; however, the effects of repetitive mild injury (rmTBI) or whether these outcomes are sex specific are unknown. Risk/reward decision making is mediated by the prefrontal cortex (PFC), which is densely innervated by catecholaminergic fibers. Aberrant PFC catecholamine activity has been documented following TBI and may underlie TBI-induced risky behavior. Here, we exposed rats to sham (no injury), single, or three closed-head controlled cortical impact (CH-CCI) injuries to characterize the effects of rmTBI on 1) risk/reward decision making behavior using a probabilistic discounting task (PDT) and 2) levels …

Declined memory is a hallmark of Alzheimer’s disease (AD). Experiments in rodents and human postmortem studies suggest that serotonin (5-hydroxytryptamine, 5-HT) plays a role in memory, but the underlying mechanisms are unknown. Here, we investigate the role of 5-HT 2C receptor (5-HT2CR) in regulating memory. Transgenic mice expressing a humanized HTR2C mutation exhibit impaired plasticity of hippocampal ventral CA1 (vCA1) neurons and reduced memory. Further, 5-HT neurons project to and synapse onto vCA1 neurons. Disruption of 5-HT synthesis in vCA1-projecting neurons or deletion of 5-HT2CRs in the vCA1 impairs neural plasticity and memory. We show that a selective 5-HT2CR agonist, …

Analyzing The Effect Of The Construction Safety Audit Model Using The Business Process Model And Notation (Bpmn) Method On Improving Communication And Collaboration Between Stakeholders., Muhammad Ghazali, Danang Budi Nugroho, Yusuf Latief

CSID Journal of Infrastructure Development

The significant increase in infrastructure development is directly proportional to the rising accident rate in the construction sector, making it one of the highest-risk sectors for accidents. This phenomenon indicates that existing construction safety audits have not been effective in preventing accidents, largely because audits are generally conducted only at the construction stage. Audits at the design stage, however, have the potential to impact accident prevention significantly. Therefore, this research aims to develop a construction safety audit model using the Business Process Model and Notation (BPMN) and analyzes the impacts on stakeholder communication and collaboration. BPMN was chosen because it …

Dynamic Modeling And Tracking Of 3-Wheels Omni-Directional Mobile Robot With Manual Pid Tuning Method, Soe Soe Htay, Khaing Win Phyu, Su Yadanar, Wut Yi Win, Min Thu Soe

Platform: A Journal of Engineering (PAJE)

This paper presents the dynamic modelling and tracking control of a holonomic 3-wheel omni-directional mobile robot. A proportional integral derivative (PID) controller is used, and its performance depends on the dynamic model’s accuracy. The controller design for the switched non-linear system is based on both a dynamic model and a kinematic design. A proposed dynamic model averages the contact radius of the 3-wheels. The resultant dynamic model, on average, is non-linear and smooth, serving as a potential solution for model-based control design. The closed-loop simulation results clearly illustrate the dynamic characteristics of the 3-wheels omni-directional mobile robot, offering valuable insights …

How can short-lived molecules selectively maintain the potentiation of activated synapses to sustain long-term memory? Here, we find kidney and brain expressed adaptor protein (KIBRA), a postsynaptic scaffolding protein genetically linked to human memory performance, complexes with protein kinase Mzeta (PKMζ), anchoring the kinase's potentiating action to maintain late-phase long-term potentiation (late-LTP) at activated synapses. Two structurally distinct antagonists of KIBRA-PKMζ dimerization disrupt established late-LTP and long-term spatial memory, yet neither measurably affects basal synaptic transmission. Neither antagonist affects PKMζ-independent LTP or memory that are maintained by compensating PKCs in ζ-knockout mice; thus, both agents require PKMζ for their effect. …
