Exploring The Neural Mechanisms Of Physics Learning, Jessica E. Bartley

FIU Electronic Theses and Dissertations

This dissertation presents a series of neuroimaging investigations and achievements that strive to deepen and broaden our understanding of human problem solving and physics learning. Neuroscience conceives of dynamic relationships between behavior, experience, and brain structure and function, but how neural changes enable human learning across classroom instruction remains an open question. At the same time, physics is a challenging area of study in which introductory students regularly struggle to achieve success across university instruction. Research and initiatives in neuroeducation promise a new understanding into the interactions between biology and education, including the neural mechanisms of learning and development. These …

A Mixed Method Study Of Prospective Teachers' Epistemic Beliefs And Web Evaluation Strategies Concerning Hoax Websites, Jennifer Coccaro-Pons

FIU Electronic Theses and Dissertations

Teachers need to be equipped with the tools necessary to evaluate content on the Internet and determine if it is a credible source, or a hoax website since they are expected to instruct and prepare students on how to evaluate the sites which is now a relevant phenomenon. The purpose of the mixed‑method study was to obtain an understanding of the web evaluation strategies of prospective teachers regarding the evaluation of hoax websites and how their epistemic beliefs may influence their evaluation. Another aspect of this study was to find out what outcomes resulted from providing guidance, or not to …

Elemental Analysis Of Adhesive Tapes By Laser-Based Methods, Claudia Martinez Lopez

FIU Electronic Theses and Dissertations

Adhesive tapes are a common type of evidence involved in violent crimes and national security threats. This research evaluated the utility of LA-ICP-MS and LIBS for the characterization of the trace elemental signature in adhesive tapes for forensic comparisons. LA-ICP-MS and LIBS methods were developed, for the first time, for the qualitative and quantitative analysis of adhesive tapes.

The backings of 90 black electrical tapes, previously characterized by conventional techniques (physical examination, IR, Py-GC-MS, and SEM-EDS), were analyzed by LA-ICP-MS to evaluate the ability of the technique to discriminate samples originating from different sources and to associate pieces of tapes …

Fundamental Mechanistic Studies On The Ultrasonic Treatment Of Problematic Water Pollutants And Toxins, Danni Cui

FIU Electronic Theses and Dissertations

Problematic organic pollutants in industrial and drinking water sources are a leading cause of water scarcity. Among the advanced oxidation processes, sonolytic degradation has received considerable attention because it combines oxidation processes initiated by reactive oxidant species and a pyrolysis processes associated with the high temperatures produced during cavitation.

The degradation of the semi-volatile compound, MCHM, was rapid and followed pseudo-first order kinetics. The Freundlich kinetic model for heterogeneous systems was successfully applied to describe the non-uniform distribution of MCHM at the gas-liquid interface during ultrasonic treatment. Two primary products were confirmed by GC-MS. Computational studies were also applied to …

Cultural Politics Of Community-Based Conservation In The Buffer Zone Of Chitwan National Park, Nepal, Yogesh Dongol

FIU Electronic Theses and Dissertations

The dissertation research examines the socio-economic and political effects of community-based conservation initiatives within the Bagmara buffer zone community forests of Chitwan National Park, Nepal. In particular, the study investigates the role of buffer zones creation in structuring the way rural property rights have been defined, negotiated, and contested, in reinforcing or reducing patterns of ethnic dominance and exclusion, and in influencing how cultural identities are constituted and renegotiated. Using a political ecology framework with a specific focus on theoretical concepts of environmentality and territorialization, I conducted 12 months ethnographic and quantitative survey field research in the buffer zone communities …
