Artefacts And Influence In Curriculum Policy Enactment: Processes, Products And Policy Work In Curriculum Reform, Karen Lambert, Laura Alfrey, Justen O’Connor, Dawn Penney

Research outputs 2014 to 2021

Artefacts are an important part of policy work, and a means of representation, translation, re-negotiation, and resistance of policy. While research has established their integral role in policy enactment, little research has examined the production and/or dissemination of artefacts by teacher educators. This paper reports and analyses the production and re-production of a specific set of artefacts, arising from the policy work of four teacher educators seeking to influence the interpretation and enactment of the Australian Curriculum in Health and Physical Education (AC HPE). Analysis and discussion pursue: the rationale for producing a set of artefacts focusing on a particular …

Our Diversity Is Our Strength: Explaining Variation In Diversity, Equity, And Inclusion Emphasis In Municipal Arts And Cultural Plans, Carolyn G. Loh, Amanda Ashley, Leslie Durham, Karen Bubb

Urban Studies and Planning Faculty Research Publications

Problem, Research Strategy and Findings: Municipal arts and cultural plans direct significant amounts of public investment and set far-reaching policies, as arts and culture investment becomes an increasingly widespread economic development strategy. While these plans frequently advertise the city’s diversity, they often lack specific strategies for supporting diversity, equity, and inclusion. In addition, the creation of these plans often does not involve urban planners, nor do the plans often connect to the city’s comprehensive plan or contain the types of fact bases and commitments to equity that comprehensive plans do. In this study of 64 US municipal arts and cultural …

Human-Centered Cybersecurity Research — Anthropological Findings From Two Longitudinal Studies, Anwesh Tuladhar

USF Tampa Graduate Theses and Dissertations

Cybersecurity is a pressing issue. Researchers have proposed numerous security solutions over the years in order to combat security issues but it is still common to find known, well understood security issues in production environments. In this thesis, I seek to find the underlying reasons to why existing security solutions and best practices are not consistently applied and how to improve the utilization of secure best practices. To this end, I adopt the anthropological research method of long term participant observation and embed myself in real-world settings in order to understand the existence of security issues and the perception of …

Analysis Of Multi Resonant Switched Capacitive Converter With Imbedded Pcb Elements, Adel Lahham

Master's Theses

The data center industry is headed towards a lower point of load voltages with increased load demands contributing to higher I2R losses in power busses. Raising the bus voltage from 12V to 48V is a popular area investigated today for reducing power delivery losses. Switched capacitive converters (SCCs) are a popular topology used for this purpose. However, SCCs suffer from low tolerance for operating conditions and are unregulated. The proposed multi resonant switched capacitor buck converter (MRSCBC) can resolve these challenges while also providing output regulation. Switch mode power supplies exhibit high electromagnetic noise and with an increased number of …

Quantification Of Red Blood Cell Deformability And Distribution In Venous Valve Mimics, Zyrina Alura Calderon Sanchez

Master's Theses

Red blood cells (RBCs) are vital to sustaining life as they are necessary for microvascular oxygenation and tissue perfusion, as well as inflammation and hemostasis. RBC deformability plays a key role in their distribution in blood vessels, and hence directly influences pathophysiology of sickle cell disease and deep vein thrombosis. In this study, we tested the hypothesis that RBC deformability will affect their distribution in venous valve pockets, the location of venous thrombosis. To test this hypothesis, we used confined microfluidic flows to quantify RBC deformability, and manipulated membrane cholesterol to alter RBC deformability. The effect of RBC deformability changes …

Efficient Polyhydroxyalkanoate Production By Rhodopseudomonas Palustris From Lignocellulosic Biomass, Brandi Brown

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Polyhydroxyalkanoates (PHAs) are biopolymers produced by bacteria with the potential to replace conventional plastics. However, the relatively high production costs of PHAs are keeping them from market acceptance, with approximately half of the production costs derived from the feedstock. Thus, engineering a microbe for PHA production from cheaper and renewable carbon sources is necessary to promote the valorization of PHAs. Lignocellulosic biomass is considered to be one of the most economic carbon sources in the world, and is thus an attractive candidate for cheaper production of bioplastics. Rhodopseudomonas palustris CGA009 is a metabolically robust bacterium capable of catabolizing lignin breakdown …

Concepts For Rapid-Refresh, Global Ocean Surface Wind Measurement Evaluated Using Full-System Parametric Extrema Modeling, M. Patrick Walton

Theses and Dissertations

Satellite wind vector data is integral to atmospheric models and forecasts. Currently, the limited refresh rate of global wind vector measurement systems makes it difficult to observe diurnal variation of mesoscale processes. Using advancements in the underlying subsystem technologies, new satellite wind scatterometers may be possible that increase temporal resolution, among other performance metrics. I propose a method for parametrically modeling the extreme performance range of a complex system. I use this method to develop a model of the space of possible satellite wind scatterometer designs. I validate the model using point designs of heritage scatterometers. Finally, I present two …

Pre-Columbian Cultivation Of Agave Species Through Rock Mulching: Potential For Modern Applications, Hector Genaro Ortiz Cano

Theses and Dissertations

As global temperatures rise, cultivation of C3 and C4 crops in arid and semi-arid regions will face major challenges in producing biomass for billions of people. Conventional agricultural techniques that require copious irrigation will need to be complemented with dryland-farming techniques and drought-tolerant crops, such as those from the Agave genus, which use CAM photosynthesis. In the past and present, humans from arid and semi-arid regions of America have maintained a symbiotic relationship using and cultivating Agave (Agavoideae, Asparagaceae).
