Surveying First-Year Stem Students’ Self-Reported Knowledge, Skills, And Attitudes Towards Teamwork, Gregory R. Goldsmith, Camilla Acosta

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The ability to work in a team is cited as a key outcome for many undergraduate Science, Technology, Engineering, and Mathematics (STEM) programs, both as a method for improving learning and as a highly desired trait for employers. Despite a growing focus on teamwork, our ability to design appropriate teamwork curriculum is limited by our poor understanding of what students arriving at university know about teamwork, what teamwork skills they consider themselves to possess, and their attitudes towards teamwork. We delivered a mixed-methods survey to first-year STEM undergraduate students (n = 205) to benchmark knowledge, skills and attitudes towards …

Using “You” As A Subject In Biology Assessment Questions: Examining Student Preferences For Second-Person Framing, Noelle Clark, Kate Hill, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

In college biology courses, exams and quizzes are often used to assess students’ knowledge and performance. Since assessments are a crucial part of biology classes, there has been a wide range of work examining how assessment questions are written, revealing that small changes in how such questions are worded may have large impacts on students’ reading comprehension and performance. One aspect that instructors consider when writing a question is subject framing, i.e., which individual, if any, is being placed as the focal point of the question. In this study, we focus on the following subject framings, an authentic scientist, a …

International Journal of Speleology

Cave ecosystems host specialized phototrophic biofilms structured primarily by light availability, yet quantitative assessments of aerophytic microalgal community organization in tropical limestone caves remain limited. This study investigated spatial variation in the structure of aerophytic microalgal communities across four ecologically distinct zones (entrance, transition, penetration, and low light) of Gua Tempurung, Malaysia. Stratified sampling was conducted during three seasonal periods. Dominant phototrophic morphospecies were identified using microscopy, and community composition was analyzed in relation to key environmental variables. Twenty-three dominant microalgal morphospecies were recorded across the cave gradient. Cyanobacteria constituted the major component of both richness and abundance, followed by …

Supramolecular Assembly In Short Peptide Systems For Selective Metabolite Recognition And Drug Nanoencapsulation, Maithreyi Ramakrishnan

Dissertations, Theses, and Capstone Projects

Short peptides can form adaptive supramolecular assemblies, and understanding how minimal sequences organize around neurometabolites or hydrophobic cancer drugs enables the rational design of functional materials. This thesis combines molecular dynamics with experimental validation to establish design rules linking peptide sequence to emergent structure and function. Chapter 1 outlines the molecular determinants governing peptide assembly. Chapter 2 reviews computational workflows that reveal sequence-dependent conformations and supramolecular organization. Chapter 3 applies these principles to Dynamic Peptide Libraries which identify tetrapeptides that selectively interact with neurometabolites. Chapter 4 extends the same interaction-driven framework to design tryptophan-rich pentapeptides that co-assemble with kinase inhibitors …

All Dissertations

With guidance from the EPA to reduce virgin packaging use and alternatively increase reuse, the concept of reusable packaging has re-emerged as a potential sustainable alternative to single-use and recyclable packaging. For businesses, an understanding of the potential environmental benefits of switching from single-use packaging to reusable packaging, along with consumer willingness to pay for sustainable packaging are paramount. Existing literature on willingness to pay (WTP) for ethical or sustainable products typically relies on consumers’ stated preferences found through surveys using hypothetical products and prices. It has been revealed that sustainability claims printed on the label or products in glass …

Feeding Ecology In Coastal Systems, Randi L. Cannon

Graduate Theses and Dissertations (2019 - present)

Oysters (Crassostrea virginica) are critical foundation species in estuaries, providing numerous ecological and economic benefits. However, oyster populations have diminished worldwide. Effective oyster restoration and aquaculture require a mechanistic understanding of the physiological and environmental factors that govern oyster feeding, growth, and resilience under changing coastal conditions. We investigated how oyster ploidy and environmental conditions influenced oyster feeding and investigated how changes in abiotic conditions affected behavioral performance of oyster drills (Stramonita spp.), a key oyster predator. To better understand feeding responses and behaviors of both predator and prey we 1) used in-situ filter feeding assays to determine if feeding …

Use Of Basal Tree Cavities By Sylvilagus Aquaticus In Central Arkansas, Heath R. Williams

ATU Scholars Symposium

Basal tree cavities are hollow structures at the base of tree trunks utilized by many wildlife species, including small mammals, furbearers, and bats. Dumyahn and Zollner (2010) demonstrated that swamp rabbits (Sylvilagus aquaticus) use basal tree cavities and speculated that they may be used for thermoregulation at the northern limits of their geographic range or as alternative escape routes. To further investigate swamp rabbit use of basal tree cavities, we placed camera traps approximately 1 m from the entrance of the cavities (n = 43) in various Wildlife Management Areas in central Arkansas. Along with control sites without cavities (n=25), …

Curriculum For A Two Semester Calculus Course Specializing In Life Science And Data Science, Patrick Mcclain

LSU Master's Theses

Traditionally, introductory calculus has been designed for engineering and physics students, often leaving students majoring in data science or life sciences with a curriculum that lacks professional relevance and is overly reliant on problems that focus on computational fluency. This thesis proposes a two-semester sequence, called MATH 153X and MATH 154X, specifically tailored for the Louisiana State University (LSU) Dual Enrollment program and university-level data science and life sciences majors. By integrating modern computational tools—such as symbolic calculators and artificial intelligence (AI) tools—the proposed curriculum shifts the pedagogical focus from procedural symbolic manipulation toward conceptual literacy.

Research Data

The following dataset pertains to Python scripts of an agent-based model simulating various drone survey design and quantifying potential count bias of stationary animals in fixed landscapes as part of an accepted manuscript in Ecosphere. Simulated animals were distributed among five animal densities (n = 4, 9, 25, 49, 100 animals/survey area) and three distribution patterns (random, uniform, aggregated). Eight drone flight patterns surveyed a 4.16-km² landscape within constraints of real-world battery and line-of-sight limitations. The simplified landscape also provided 100% animal classification (i.e., all animals within image frame observed and identified).

Effects Of Volatile Organic Compounds Produced By Temperature-Adapted Microbes On Duckweed Growth, Phaedra Yael Stemp

Honors Theses and Capstones

As host-associated microbes adapt to their abiotic environment, these adaptations can affect their host species as well. Previous research showed that varying temperatures and volatile organic compound (VOC) production can affect microbial benefits to hosts. This experiment analyzed how 27 microbes pre-adapted to different temperature conditions affected growth of their host, common duckweed plants, comparing effects of direct contact with microbes, effects of microbe VOCs alone, or both. Each microbe was pre-adapted to one of three temperature regimes: “Northern” at 28 °C, “Southern” at 33 °C, and “Extreme” at 36 °C. We then grew duckweeds in I-plates with each microbe …

Exploration Of The Use Of Radiocarbon Time-Series Records As Indicators Of Upwelling Areas, Rena Reshmi Mukherjee

CMC Senior Theses

The Earth’s oceans buffer climate change, regulate weather patterns, sustain global food security, and support biomedical research. Ocean currents redistribute heat and nutrients while promoting genetic diversity, which can serve as a source of novel compounds for biomedical research. Understanding ocean circulation is essential for maintaining these ecosystem services as the climate continues to change. Upwelling, a form of vertical water movement that transports nutrient-rich deep water to the surface, plays a key role in marine productivity and carbon cycling. However, global upwelling patterns remain incompletely mapped. Radiocarbon (14C), a radioactive isotope of carbon, provides a useful tracer of ocean …

Development Of The Core Lit Apparatus For Seaweed Hatcheries (Clash) Bioreactor Using A Germplasm Approach, Phillip O. Tahimic

Cal Poly Humboldt theses and projects

In comparison to the Asian aquaculture industry, the United States has minimal seaweed production. There are several drivers of the limited industry in the US, such as regulatory constraints and limited market demand, but the ability to scale is a considerable barrier to commercialization. One possible solution is the development of land-based systems that integrate bioreactors, which utilize fewer resources and do not wholly rely on an oceanic flow-through system. This study assessed the application of a modular bioreactor, known as Core Lit Apparatus for Seaweed Hatcheries (CLASH), as a nursery system and open-source project designed to expand land-based seaweed …

The Role Of Resistance Training In Managing Menopause-Related Changes, Alyson K. Strauss

Honors Undergraduate Theses

Resistance training serves as a critical non-pharmacological strategy for mitigating the physiological and psychological declines associated with the menopausal transition. This natural biological phase, marked by declining estrogen levels, typically leads to accelerated bone mineral density loss, sarcopenia, metabolic regulation disturbance, and heightened mood disturbances. To evaluate the efficacy of targeted exercise interventions, a systematic review was conducted following PRISMA guidelines. From an initial pool of 60 relevant articles, 13 studies met the specific inclusion criteria, focusing on structured resistance training protocols for perimenopausal, menopausal, and postmenopausal cohorts.

The synthesis of these studies indicates that resistance training is a highly …
