Name, Image, and Likeness Rights as a Means to Student-Athlete Self-Authorship

Today, the common discourse surrounding student-athletes’ Name, Image, and Likeness (NIL) Rights is evolving from an archaic sense of paternalism and conservative protectionism to various forms of redistribution such as salaries and endorsement rights. Although I have found the NCAA’s protectionist stance on amateurism to be outdated, I do not find the salarying of student-athletes to be tenable for the majority of higher education institutions. The NCAA should roll back their codes (2.9, 2.13, 12.4.4, 15.1, in particular) restricting student-athlete NIL rights in order to maximize these students’ potential for self-authorship. To support student-athletes bfore, during, and after this legislative change, I am proposing a Self-Authorship Seminar, which could take the form of a voluntary meeting or even a 3-credit course, depending on the preferred style of implementation at a given institution. This seminar/course is designed to address the cognitive, interpersonal, and intrapersonal dimensions of Marcia Baxter-Magolda’s (2001) Theory of Self-Authorship through group discussions on academic growth and engagement, personal ethics and values, and relationship-building, as well as writing labs to hone students’ communication and advocacy skills

Developing a more holistic approach to teaching, learning and assessment

Stories in this research study were used to provide authentic design and technology contexts for Key Stage 2 (11 year old pupils) and Key Stage 3 (13 year old pupils), in two different schools. Both learning contexts involved the pupils in problem solving and creative working in groups, two key skills of business and commerce. Dilemma, mystery and intrigue within the different stories invited the pupils to think, act, and reflect on a number of open-ended issues, some of which had no immediate or obvious answers. Classrooms for the 21st Century, it is argued (Marton et al., 1993; Wallace, 1996; Watkins, 2001), need to provide contexts for learning that will encourage children to think logically, critically and creatively, to reason and reflect, and be less dependent on their teachers. These qualities are essential if pupils are to be equipped with the learning dispositions and capability needed to manage complexity and uncertainty, and engage in futures yet to be envisaged. Both stories were used to stimulate and initiate purposeful Design and Technology activity that challenged pupils to think and act, individually and collectively. The stories provided new environments for pupils to think in and be creative, and helped place concepts in real and meaningful contexts (Vygotsky, 1987)

Waiting time distributions for queues with single server, poisson arrivals, and erlang and uniform service

The problem considered in this thesis is that of finding the probability distribution of waiting times in a queueing system consisting of: 1- a single server; 2- interarrival times are independent random variables each having the exponential distribution; and 3- service times are independent random variables having either the Erland or uniform distribution

Displacement operators: the classical face of their quantum phase

In quantum mechanics, the operator representing the displacement of a system in position or momentum is always accompanied by a path-dependent phase factor. In particular, two non-parallel displacements in phase space do not compose together in a simple way, and the order of these displacements leads to different displacement composition phase factors. These phase factors are often attributed to the nonzero commutator between quantum position and momentum operators, but such a mathematical explanation might be unsatisfactory to students who are after more physical insight. We present a couple of simple demonstrations, using classical wave mechanics and classical particle mechanics, that provide some physical intuition for the phase associated with displacement operators.Comment: 14 pages, 4 figures, reorganized and reformatte

Graph Nodal Domains and Data

This thesis proposes and develops a graph spectral flow for computing nodal counts and nodal deficiencies of graph Laplacian eigenvectors. Background on Laplace eigenfunctions and their nodal domains, as well as the corresponding results in the spectral graph theory literature, is given. We also review some effective tools that adapt spectral methods for the analysis of data, in particular the use of ratio cuts for partitioning and diffusion maps for dimensionality reduction. We then define two versions of the graph spectral flow and develop properties of each, after which examples of the spectral flow on a number of graphs are provided. Finally we mention ongoing lines of research related to both theoretical and applied aspects of graphs' nodal counts.Doctor of Philosoph

Impulsive Spin-Motion Entanglement for Fast Quantum Computation and Sensing

We perform entanglement of spin and motional degrees of freedom of a single, ground-state trapped ion through the application of a $16$ ps laser pulse. The duration of the interaction is significantly shorter than both the motional timescale ($\approx 10$ $\mu$s) and spin precession timescale ($\approx 10$ ns), demonstrating that neither sets a fundamental speed limit on this operation for quantum information processing. Entanglement is demonstrated through the collapse and revival of spin coherence as the spin components of the wavefunction separate and recombine in phase space. We infer the fidelity of these single qubit operations to be $97(3)\%$.Comment: 5 pages, 4 figure

Starting Anti-COVID-19 Drug Discovery with Natural Products

COVID-19 was characterized as a pandemic regarding its rapid international spread and severity on March 2020. The Coronaviridae family receives this name regarding the organization of the spike glycoprotein located in the envelope, which resembles a stellar corona when observed under a microscope. Coronaviruses undergo frequent mutations in their genome due to errors made by RNA-dependent RNA polymerase (RdRp). The SARS-CoV-2 was characterized by high infectivity and person to person transmission, with an incubation period of up to fourteen days. Potent antiviral activities of several natural products such as alkaloids, chalcones, triterpenoids have been reported but with unconfirmed efficacy or safety in the clinic as well as the complete underlying mechanisms. Also, CQ, HCQ and Ivermectin, remdesivir, lopinavir, ritonavir, favipiravir and pegylated interferon with ribavirin have been tested to develop both an effective therapy and a vaccine to treat COVID-19.  This study presents the antiviral effects of the natural products against SARS-CoV, HCoV-NL63, HCoV-229E and HCoV-OC43 showing that Lycorine, Emodin, Promazine, Saikosaponins B2, Silvestrol, Cepharanthine, Fangchinoline, Tetrandrine, Caffeic acid, Chlorogenic acid, Gallic acid and Emetine are a good candidates on treatment of coronaviruses infections.La COVID-19 se caracterizó como una pandemia debido a su rápida propagación y severidad en marzo de 2020.
