Breakdown and classification of skill transfer type between a hockey slap shot and golf drive

There is surprisingly little scientific literature describing whether a hockey slap shot positively or negatively transfers to a driving golf swing. Golf and hockey use a similar kinematic sequence to send the ball / puck towards a target, but does that directly translate to positive skill transfer between the two sports, or are there other important factors that could result in a negative skill transfer? The aim of this study is to look further into the two kinematic sequences and determine their intertask skill transfer type. A field experiment was conducted, following a specific research design, in order to compare performance between two groups, one being familiar with the skill that may transfer (hockey slapshot) and the other group being unfamiliar. Both groups had no experience in the skill being tested (driving golf swing) and various data was collected as all of the subjects performed 10 golf swings. The results of the data analysis showed that the group with experience in hockey had a higher variability of ball distance and ball speed. There are many factors of a hockey slapshot that are likely to develop a negative intertask skill transfer, resulting in this group's high inconsistency when performing a golf swing. On the other hand, the group with hockey experience also had higher mean club speed, showing that some aspects of the hockey slapshot resulted in a positive skill transfer, aiding their ability to perform a golf swing.

The following creative project defends that, whether intentionally or not, mental illness and substance abuse are inevitably romanticized in young adult media and discusses the dangers of this romanticization. This project is divided into three parts. The first part consists of psychological evaluations of the main characters of two popular, contemporary forms of young adult media, Catcher in the Rye by J.D Salinger and Euphoria by Sam Levinson. These evaluations use textual evidence and the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) to determine what symptoms of psychopathology the characters appear to display. The second part consists of a self-written short story that is meant to accurately depict the life of a young adult struggling with mental illness and substance abuse. This story contains various aesthetic techniques borrowed from the two young adult media forms. The final part consists of an aesthetic statement which discusses in depth the aesthetic techniques employed within the short story, Quicksand by Anisha Mehra.

The limitations and extent of category generalization within a partially learned hierarchical structure

Description

Most people are experts in some area of information; however, they may not be knowledgeable about other closely related areas. How knowledge is generalized to hierarchically related categories was explored. Past work has found little to no generalization to categories

Most people are experts in some area of information; however, they may not be knowledgeable about other closely related areas. How knowledge is generalized to hierarchically related categories was explored. Past work has found little to no generalization to categories closely related to learned categories. These results do not fit well with other work focusing on attention during and after category learning. The current work attempted to merge these two areas of by creating a category structure with the best chance to detect generalization. Participants learned order level bird categories and family level wading bird categories. Then participants completed multiple measures to test generalization to old wading bird categories, new wading bird categories, owl and raptor categories, and lizard categories. As expected, the generalization measures converged on a single overall pattern of generalization. No generalization was found, except for already learned categories. This pattern fits well with past work on generalization within a hierarchy, but do not fit well with theories of dimensional attention. Reasons why these findings do not match are discussed, as well as directions for future research.

Modeling the TyrZ-His 190 pair of photosystem II for the study of proton coupled electron transfer

Description

The work described in the thesis involves the synthesis of a molecular triad which is designed to undergo proton coupled electron transfer (PCET) upon irradiation with light. Photoinduced PCET is an important process that many organisms use and the elucidation of its mechanism will allow further understanding of this process and its potential applications. The target compound designed for PCET studies consists of a porphyrin chromophore (also a primary electron donor), covalently linked to a phenol-imidazole (secondary electron donor), and a C60 (primary electron acceptor). The phenol-imidazole moiety of this system is modeled after the TyrZ His-190 residues in the reaction center of Photosystem II (PS II). These residues participate in an intermolecular H-bond between the phenol side chain of TyrZ and the imidazole side chain of His-190. The phenol side chain of TyrZ is the electron transfer mediator between the oxygen evolving complex (OEC) and P680 (primary electron donor) in PSII. During electron transfer from TyrZ to P680*+, the phenolic proton of TyrZ becomes highly acidic (pKa~-2) and the hydrogen is preferentially transferred to the relatively basic imidazole of His-190 through a pre-existing hydrogen bond. This PCET process avoids a charged intermediate, on TyrZ, and results in a neutral phenolic radical (TyrZ*). The current research consists of building a molecular triad, which can mimic the photoinduced PCET process of PSII. The following, documents the synthetic progress in the synthesis of a molecular triad designed to investigate the mechanism of PCET as well as gain further insight on how this process can be applied in artificial photosynthetic devices.

Wireless power transfer

A new loop configuration capable of reducing power radiation magnitudes lower than conventional loops has been developed. This configuration is demonstrated for the case of two coaxial loops of 0.1 meter radius coupled via the magnetic reactive field. Utilizing electromagnetism theory, techniques from antenna design and a new near field design initiative, the ability to design a magnetic field has been investigated by using a full wave simulation tool. The method for realization is initiated from first order physics model, ADS and onto a full wave situation tool for the case of a non-radiating helical loop. The exploration into the design of a magnetic near field while mitigating radiation power is demonstrated using an real number of twists to form a helical wire loop while biasing the integer twisted loop in a non-conventional moebius termination. The helix loop setup as a moebius loop convention can also be expressed as a shorted antenna scheme. The 0.1 meter radius helix antenna is biased with a 1MHz frequency that categorized the antenna loop as electrically small. It is then demonstrated that helical configuration reduces the electric field and mitigates power radiation into the far field. In order to compare the radiated power reduction performance of the helical loop a shielded loop is used as a baseline for comparison. The shielded loop system of the same geometric size and frequency is shown to have power radiation expressed as -46.1 dBm. The power radiated mitigation method of the helix loop reduces the power radiated from the two loop system down to -98.72 dBm.

Relationship between Motor Generalization and Motor Transfer

Description

Adapting to one novel condition of a motor task has been shown to generalize to other naïve conditions (i.e., motor generalization). In contrast, learning one task affects the proficiency of another task that is altogether different (i.e. motor transfer). Much

Adapting to one novel condition of a motor task has been shown to generalize to other naïve conditions (i.e., motor generalization). In contrast, learning one task affects the proficiency of another task that is altogether different (i.e. motor transfer). Much more is known about motor generalization than about motor transfer, despite of decades of behavioral evidence. Moreover, motor generalization is studied as a probe to understanding how movements in any novel situations are affected by previous experiences. Thus, one could assume that mechanisms underlying transfer from trained to untrained tasks may be same as the ones known to be underlying motor generalization. However, the direct relationship between transfer and generalization has not yet been shown, thereby limiting the assumption that transfer and generalization rely on the same mechanisms. The purpose of this study was to test whether there is a relationship between motor generalization and motor transfer. To date, ten healthy young adult subjects were scored on their motor generalization ability and motor transfer ability on various upper extremity tasks. Although our current sample size is too small to clearly identify whether there is a relationship between generalization and transfer, Pearson product-moment correlation results and a priori power analysis suggest that a significant relationship will be observed with an increased sample size by 30%. If so, this would suggest that the mechanisms of transfer may be similar to those of motor generalization.

Utilizing the prospect of transfer to increase academic engagement in high school equivalency students within a wicked problems framework

Description

This study examined the influence of perceived transfer of learning on student engagement, completion rates, and attendance hours of high school equivalency (HSE) students within a Wicked Problems Framework. Local research had shown that over 30% of HSE students stopped

This study examined the influence of perceived transfer of learning on student engagement, completion rates, and attendance hours of high school equivalency (HSE) students within a Wicked Problems Framework. Local research had shown that over 30% of HSE students stopped attending HSE classes prior to completing 40 instructional hours, and many students cited a lack of relevant, “real-world” application, and the need to pursue employment as the two most common reasons that they stopped attending.

To address this issue, an innovation was developed and deployed for one semester at the Rio Salado College Avondale location. The innovation identified the individual career interests of each student in a treatment group, then worked with industry experts in those career fields to develop PowerPoint slides explaining how each HSE math lesson would directly transfer to the student’s career of interest. In addition, hiring managers from each career field that the students expressed interest in visited the class to discuss the need for HSE math skills and to answer any questions about their career and the transferability of what the students were learning.

The treatment groups’ attendance hours, completion rates, and self-reported engagement were examined and compared all other HSE math classes at Rio Salado College that took place during the same semester, as well as compared to the instructor of the innovation’s previous math classes. The results showed that students who participated in the innovation had, on average, over 38 more attendance hours than students who did not receive the innovation during the same semester and over 44 more attendance hours than the instructor’s previous classes at the same location. In addition, students who participated in the innovation reported higher engagement and enjoyment in the class than in similar HSE classes that they had previously taken.

Middle School Students' Engagement with Grammar in a Transfer-Minded Approach to Instruction

Description

This qualitative, classroom-based study investigates how 24 middle school students engaged with grammar in an instructional approach that bridged “grammar in context” practices with writing transfer practices. This “transfer-minded” approach invited students to monitor and reflect on their grammar choices

This qualitative, classroom-based study investigates how 24 middle school students engaged with grammar in an instructional approach that bridged “grammar in context” practices with writing transfer practices. This “transfer-minded” approach invited students to monitor and reflect on their grammar choices in writing as a way to foster metacognition; it also guided students to consider other and future writing contexts where they could use the grammar they were learning as a way to foster transfer and long-term writing development. The dissertation findings detail the role of individual factors on student engagement with grammar in this study. The findings also share how students thought about and used grammar in their writing. Finally, the dissertation reveals how students engaged with the instructional practices, helping map successful and promising areas for effective grammar instruction.
