Does emotional intelligence matter when using expressive writing interventions in a large enrollment STEM course?

Type: Undergraduate
Author(s): Emery Green Geological Sciences
Advisor(s): Michael Pelch Geological Sciences
Location: Zoom Room 3, 02:39 PM

Anxiety related to academics, especially with regards to testing, is a rapidly growing mental health issue impacting all undergraduates at TCU. High levels of test anxiety have been shown to inhibit memory recall, reduce exam scores, and promote poor study habits. Expressive writing is a form of test anxiety intervention consisting of a type of free response developed to allow students to release their minds of anxious thoughts and emotions related to exams. Expressive writing has been shown to reduce test anxiety and improve exam performance. However, the effectiveness of expressive writing may be mitigated by a students’ level of emotional intelligence. Emotional intelligence is defined as the capacity to be aware of, control, and express one’s emotions. In order to better understand the connection between emotional intelligence and expressive writing, I conducted an exploratory mixed-methods study using quantitative survey data to inform our selection of interview participants and the initial development of my interview protocol. Initially, to gain insight into students’ responses to the expressive writing prompt, I collected and coded expressive writing samples from GEOL 10113 students during the Fall of 2020. Prior to the beginning of the semester, I asked the students to complete a Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF) to assign a numerical value to their approximate emotional intelligence levels. Next, I stratified students by quartiles into high (Q3), medium (Q2), and low (Q1) emotionally intelligent groups. Then, GEOL 10113 students were asked to participate in focus group interviews, and volunteers were subsequently grouped by their TEIQue-SF score into three focus groups relating to the high, medium, and low emotional intelligence bins. Finally, using the focus group interview data and the selected student’s responses from the initial expressive writing exercise, I found that all of the student responses showed consistent differences between the three focus groups. Highly emotionally intelligent students had more positive experiences with the expressive writing exercise while lower emotionally intelligent students tended to have neutral or negative experiences with the activity. Overall, these data suggest that the level of emotional intelligence relates to how willing students were to convey their thoughts and emotions during the activity, which helped the higher emotionally intelligent students to have positive experiences with the writing exercise. The implications of my study are that while the efficacy of the expressive writing exercise is assumed, emotional intelligence is a confounding variable. Students must engage with it in some sort of authentic manner if they are to benefit from the exercise.

Microscopic Studies of Ancient, Potentially Rift-Related Plutonic Igneous Rocks in Colorado

Type: Undergraduate
Author(s): Isabella Nino Geological Sciences Richard Hanson Geological Sciences
Advisor(s): Richard Hanson Geological Sciences
Location: Basement, Table 2, Position 3, 11:30-1:30

The regional geological framework of the area I am studying involves a possible major northwest-trending Cambrian to Ordovician rift zone with abundant igneous rocks in parts of Colorado. These igneous rocks may be related to large volumes of Cambrian igneous rocks located along the same trend in southern Oklahoma. My project focuses on plutonic igneous intrusions located in the Wet Mountains in the southern part of the Front Range and in the Powderhorn District farther west. The goal of this project is to discover whether the rocks in Colorado formed during the same major magmatic event as those in Oklahoma. I will be studying thin sections of rock samples from Colorado utilizing a petrographic microscope. I will describe and identify the main igneous minerals from the samples, some of which are rare. I will also study the igneous textures and alteration products in the samples. Geochemical studies in progress will build on these results and will allow detailed comparison with the southern Oklahoma igneous rocks.

Mapping Fertilizer Runoff in the Mississippi River Delta

Type: Undergraduate
Author(s): Amy Lam Environmental Sciences Graham Rice Environmental Sciences
Advisor(s): Esayas Gebremicharl Geological Sciences
Location: Zoom Room 5, 03:11 PM

The Mississippi River Delta is the 7th largest river delta on Earth that consists of the Mississippi River and the Gulf of Mexico. Additionally, it contains 40% of the wetlands in the contiguous United States and over two million hectares (4,942,108 acres), an area equivalent to the size of two football fields, of agricultural lands. Due to fertilizer runoff from agricultural lands, the river delta has been experienced excess levels of nitrogen and phosphorus. The excess levels of these nutrients have contributed to water pollution in the delta and the hypoxia zone in the Gulf of Mexico. This research will focus on mapping the levels of nitrogen and phosphorous across the river delta to determine where the highest levels are

Type: Undergraduate
Author(s): Benite Ishimwe Environmental Sciences Esayas Gebremichael Geological Sciences
Advisor(s): Esayas Gebremichael Geological Sciences
Location: Zoom Room 1, 03:43 PM

Rapid industrialization and global population growth have increased the number of people living in urban areas worldwide. Developing countries, have seen tremendous increases in their industries over the past decades, which generated both positives and negative effects on their people, environment, and economy. One of the negative impacts of industrialization is industrial pollution and the increase in the number of pollutants released into the environment_ in this case, heavy metals. Heavy metal contamination is an alarming problem that many Developing countries are becoming aware of and trying to address. Heavy metal direct or indirect consumption may result in several health effects in the body, including damage and alteration of normal functioning of organs such as the brain, kidney, lungs, liver, and blood, which later result into acute or chronic diseases. This case study will look at heavy metal contamination cases in Rwanda in different drinking water sources. The focus of this case study will be on some common heavy metals released from industrial waste: Lead, Manganese, Iron, Cadmium, Zinc, and Chromium.

Size Effects on Sorption of Nanomaterials to Iron Oxides

Type: Undergraduate
Author(s): Brooke Newell Geological Sciences
Advisor(s): Omar Harvey Geological Sciences
Location: Zoom Room 4, 02:31 PM

Synthetic nanomaterials continue to revolutionize how we do things industrially, medically and domestically. As we continue to utilize these materials, the inevitability of them entering the environment and the need to understand the associated consequences rises to the forefront. My research focuses on understanding the chemo-dynamics of interactions between polyamidoamine (PAMAM)-based nanomaterials (most commonly in the biomedical field through drug and gene delivery) and reactive minerals in the environment. Specifically, this presentation will cover the size-dependent binding (and debinding) dynamics of carboxyl-terminated PAMAMs (G-COOH) onto (and from) ferrihydrite (FFH), a form of naturally-occurring iron oxide mineral. Early results suggest that at pH 5, the smaller G1.5-COOH PAMAM binds to (and debinds from) FFH in higher quantities but at much slower rates that the larger G3.5-COOH PAMAM. The higher quantities of G1.5-COOH PAMAM being bound to (or debound) from FFH is attributable to its smaller size - facilitating access to internal micropore space in FFH that are inaccessible by the larger G3.5-COOH PAMAM. Difference in the accessibility of internal FFH micropore space by the different sized PAMAMs would also explain observed trends in their rates of binding and debinding. In future research, I will be targeting the confirmation of early results and the expansion of my study to include G-COOH PAMAMs larger than G3.5-COOH.

Cobalt Cache: Finding a Solution for Runaway Cobalt Demand

Type: Undergraduate
Author(s): John David Walker IV Geological Sciences
Advisor(s): Tamie Morgan Geological Sciences

Public awareness of human rights violations in cobalt-rich mines of the Democratic Republic of Congo have American cobalt consumers scrambling for reliable suppliers to meet rising demand, with uncertainties about futures in cobalt's supply chain. Global cobalt production supply forecast falls short of global demand forecast for the next ten years, even with the completions of major planned mined projects. The exponential increase in demand for cobalt results from its utility in personal electronics batteries, electric vehicle batteries, and jet engine construction. Chemical extracting operations whose sole purposes are to extract cobalt are not profitable in the status quo, leaving a window of opportunity for reclaimed cobalt to take hold in the market. This project studies consumer patterns to determine "urban mine" qualities in Texas. The resulting analysis exists to be cross-applied to other states to determine target regions best suited for cobalt reclamation strategies in hopes of securing America's geopolitical mineral stability.

Deforestation and Fragmentation in the Atlantic Forest

Type: Undergraduate

Advisor(s): Esayas Gebremichael Environmental Sciences
Location: Zoom Room 2, 01:42 PM

The Atlantic Forest, which extends over 17 Brazilian States, is one of the richest biomes in the world. Historically it has been a hot spot for biodiversity including endangered and endemic species. Despite this, only 15% of the forest’s original range remains. This loss is disproportionally distributed as 4 of the 17 states accounts for 90% of the loss. The source of this deforestation can be attributed primarily to logging developments and eucalyptus plantations. Through using public geodatabases, satellite imagery, and ArcGIS Pro we will show this forest loss and fragmentation in a visually accessible way.

Mapping geology of SW Namibia using Landsat-8 band ratios

Type: Undergraduate
Author(s): Sierra Ohrmundt Geological Sciences
Advisor(s): Tamie Morgan Geological Sciences

Landsat-8 data was used to test the effectiveness of using spectral analysis and remote sensing in the differentiation of lithological units and mapping geology in Namibia. The study area is located in SW Namibia, in an arid region with little vegetation, making it an ideal place for remote sensing analysis. Different color composites and band ratios were compared to find the image providing the most geologic information and highest contrast between units. A false color composite (6,3,2 in red-green-blue) was first created to to show differences in bare earth, and from there, various band ratio combinations were created. Geologic maps were used to verify the results and select the best band combination. The best color composite image was created using band ratios from (7/6, 6/5, 4/2), and allowed identification of lithological units and vegetation. The results show that it is possible to draw valid lithological conclusions from spectral patterns, and that high quality imagery can be used to update existing geologic maps or used for exploration.

Synthetic Nanomaterials: An Environmental Twist of Fate

Type: Undergraduate
Author(s): Brooke Newell Geological Sciences
Advisor(s): Omar Harvey Geological Sciences
Location: Basement, Table 9, Position 1, 1:45-3:45

As the nature and quantity of new/novel nanomaterials continue to expand to meet industrial, medical, and domestic demands, their accidental or intentional release becomes inevitable. To this end, an evolving understanding of the interaction dynamics between nanomaterials and naturally occurring geomaterials is central to supporting continued sustainable development and use of nanomaterials. The current study explores the chemodynamics of the organic nanomaterial, polyamidoamine (PAMAM) dendrimers, binding to (and debinding from) ferrihydrite. Specific focus is placed on how PAMAM size and pH affects the reaction between three carboxyl-terminated PAMAMs (Gx.5-COOH) sorbing/desorbing to/from the variably-charged ferrihydrite (FFH). Since both ferrihydrite and PAMAM exhibit pH-dependent variation of speciation, it is expected that binding/debinding dynamics of differing sizes of PAMAM will vary. Investigating the quantity, rate, and dynamics of these reactions provides insight into the type of bonding occurring (physiosorption, electrostatic bonding, or hydrogen bonding) and the location of bonding (surface versus micropore spaces). The information gained from this study will help to develop a more holistic picture of the environmental fate of synthetic nanomaterials.

Location: First Floor, Table 6, Position 1, 11:30-1:30

Surface water plays a critical role in meeting Texas’s water demands, particularly for municipal use. In the State of Texas, there are 188 major water reservoirs, 15 major river basins, and 8 coastal basins. These water sources serve as the lifeline of Texas’ urban and agricultural populations. In our study, we will be examining how proximity to these sources affects development, particularly focusing on population density to determine the type of population (urban or agricultural). Our findings have the potential to provide insights that can inform city water departments near major water resources with high population density and aid with water demand and scarcity management.

Fort Worth, Texas has become one of the most populated areas in the United States. With a growing influx of commuters on a daily basis, there is no doubt that there will be a large amount of car crashes in the city. According to the Texas Department of Transportation, in 2020 there were over 15,000 car crashes while in 2021 there were over 17,000 car accidents. In 2022 alone there have been over 3000 car crashes already. Many of these car crashes are likely avoidable and finding the areas that are most susceptible to these accidents will be valuable knowledge for drivers and the city. Applying ESRI ArcGIS Pro’s spatial analysis extension to the Texas Department of Transportation's car accident the roads of Fort Worth with high crash and fatality rates will be found and mapped accordingly.

Location: Third Floor, Table 3, Position 3, 11:30-1:30

As the nature and quantity of new/novel nanomaterials continue to expand to meet industrial, medical, and domestic demands, their accidental or intentional release becomes inevitable. To this end, an evolving understanding of the interaction dynamics between nanomaterials and naturally-occuring geomaterials is central to supporting continued sustainable development and use of nanomaterials. The current study explores the chemodynamics of the organic nanomaterial, polyamidoamine (PAMAM), binding to (and debinding from) ferrihydrite. Specific focus is placed on how PAMAM size affects the quantity, kinetics and dynamics for three carboxyl-terminated PAMAMs (Gx.5-COOH) sorbing/desorbing to/from the variably-charged ferrihydrite (FFH). Early results suggest that at pH 5, the smaller PAMAM G1.5-COOH sorbed/desorb to/from FFH in similar quantities but at slower rates than G3.5-COOH. Sorption/desorption was also found to occur via 1- or 2-steps with a faster surface-mediated step being followed by a slower diffusion-mediated step and the proportion of surface-mediated: diffusion-mediated sorption/desorption increasing with PAMAM size (i.e. G1.5-COOH<G3.5-COOH). This presentation will further cover results obtained with G5.5-COOH PAMAM.

Location: SecondFloor, Table 3, Position 2, 1:45-3:45

Prior to 2019, Texas used red-light traffic cameras to deter drivers from driving recklessly and running red lights. However, due to legislation signed by Governor Greg Abbott, red-light cameras are no longer used in Texas. This decision was made to ‘protect drivers' constitutional rights.’ Additionally, it was argued that these cameras increased the rate of rear-end collisions.

This study investigates the effect of removing red-light cameras in Fort Worth before and after the ban by examining the rate of different types of collisions. The location data of crash sites and police reports will be mapped using ArcGIS Pro to determine the frequency and density of these crashes.

Identifying High-potential Corridors for a Light-Rail Passenger Network in the Fort Worth, TX Metro Area

Type: Undergraduate
Author(s): Anna Claire Lindow Environmental Sciences Jack Grimm Geological Sciences
Advisor(s): Esayas Gebremicheal Geological Sciences
Location: Third Floor, Table 5, Position 1, 11:30-1:30

The Fort Worth metropolitan area faces increasing roadway congestion, automobile dependency, and growing accessibility challenges for households with limited vehicle and physical access. Although Tarrant County contains several rail assets, much of the regions' transit network remains limited in coverage and connectivity compared to neighboring systems in Dallas. Rather than proposing new infrastructure, this study aims to evaluate the existing rail corridors within Tarrant County to identify where improvements could generate the greatest mobility, equity, and connectivity benefits.

Using ArcGIS Pro, a weighted multi-criteria analysis is applied to three existing corridors where freight lines are already present: a south-to-north line dubbed the “Green Line”, with termini in Burleson and Keller, a west-to-east line dubbed the “Blue Line”, with termini in Benbrook and Arlington, and a southwest-to-northeast line dubbed the “Purple Line”, with termini in Crowley and Euless/Grapevine. Each corridor meets at Fort Worth T&P / Central stations and stops in significant population/economic centers. Buffers surrounding each corridor are analyzed to evaluate demographic demand, transportation efficiency, connectivity, and physical feasibility. Key variables include the percentage of households without vehicles, median income, senior and disability populations, highway congestion proximity, risk factors, and major destinations served.

By integrating demographic vulnerability indicators with transportation demand and physical constraints, this study identifies which existing retail corridors demonstrate greatest need and potential for targeted improvements. The results provide a GIS-based framework for prioritizing transit investments in automobile-dependent metropolitan regions and offer data-driven guidance for improving rail accessibility and connectivity across Tarrant County.

Location: Second Floor, Table 4, Position 3, 1:45-3:45

Today’s farmers must grasp a wide range of topics beyond just planting, including soil composition, weed management, nutrient requirements, weather patterns, pest control, disease prevention, equipment use, and climate considerations. Precision agriculture, a tool that allows for the visualization of data in an agricultural view to help ranchers better understand their land and how to best supply resources to their land, can be a tool to increase efficiency and production to the agricultural industry as a whole. Precision agriculture can help farmers “more precisely determine what inputs to put exactly where and with what quantities.”(GIS lounge para. 3). In this proposal we plan to demonstrate how precision agriculture with the use of Landsat satellites analyzes the greenness of vegetation using indices like the Normalized Difference Vegetation Index (NDVI). Using these tools we can use drones to collect plant height and plant count, biomass estimates, the presence of diseases and weeds, plant health and field nutrients, as well as 3D elevation and volumetric data.

A Study of Fossilized Root Colonies as Indicators of Past Water Table Levels in the Coll De Montllobar

Type: Undergraduate
Author(s): Daphne Varmah Geological Sciences
Advisor(s): John Holbrook Geological Sciences
Location: Basement, Table 2, Position 1, 1:45-3:45

The Coll de Montllobar cliffs in the Pyrenees Mountains contain plant fossils known as root models, which show signs of oxidation and reduction along a depositional dip, indicating varying environmental conditions Since plant roots do not grow below standing water levels, these fossilized roots and their distribution can serve as markers for past water table positions. This study examines whether root density decreases toward the bottom of the channels, indicating that roots stopped growing once they reached below the water table. If the roots disappear at a certain depth, it suggests that the bar was saturated at that level, stopping root growth. By analyzing the presence and absence of these roots, we aim to determine if they mark a clear boundary indicating historical water table levels. Our findings contribute to understanding past depositional environments and hydrological conditions in this region

Author(s): Amy Lam Environmental Sciences
Advisor(s): Omar Harvey Geological Sciences
Location: Zoom Room 1, 01:18 PM

The reusing, recycling, and reduction of waste streams is seen as a viable sustainability strategy. One major waste stream is coffee grounds with about 11.5 million kilograms being generated per day in America of which 90% is landfilled. This waste stream can be repurposed into usable carbon-based materials to address issues of climate, pollution, or engineering applications. For my research, I am converting spent (used) coffee grounds into biochars, a type of carbon-based material, with different charring (burning) temperature to measure the removal of lead (Pb2+) from contaminated water. The charring temperature was changed in order to determine the optimal charring temperature for water treatment. This presentation will go into the maximum amount of lead the biochars can remove, how fast the biochars can remove the lead and the properties of biochars that allow for such removal. Further results, methodology, and modeling applications will be discussed in the presentation.
