Impacts Of Climate Change On Vertical Migration Of Zooplankton Species, Camila Rimoldi Ibañez

Florida Atlantic Undergraduate Research Journal

Vertical migration in marine and freshwater environments stands as one of Earth’s largest daily animal movements concerning biomass. It serves as a crucial life pump, shaping phytoplankton grazing patterns, facilitating nutrient transport through the water column, and providing vital sustenance for deep-water organisms lacking access to surface phytoplankton. Despite enduring millennia of climatic shifts, contemporary anthropogenic climate change surpasses historical rates of change, posing unprecedented challenges. Climate-induced phenomena increasingly affect various species, including vertical migrators. This paper delves into Diel Vertical Migration’s ecological significance and anticipates detrimental effects of climate change on individual animals’ physiology and migration patterns. Foremost, rising …

A Comparative Analysis Of The Voicing Systems In Tagalog And Hiligaynon, Ty Craaybeek

Florida Atlantic Undergraduate Research Journal

Tagalog and Hiligaynon are both languages from the Philippines that use the unique Philippine-style topic marking system. This system illustrates a special relationship between the verb and the subject or object through an affix marking focus. Tagalog is well-studied, but there is much debate on its voicing system. Hiligaynon and its voicing system are understudied. This paper explores the voicing system in both languages to better understand their similarities. Tagalog and Hiligaynon have related voicing systems, however, Tagalog uses five voices, separating the beneficiary and locative voices, while Hiligaynon has four, combining these two voices into the referential voice.

Infants’ interactions with toys play a crucial role in their early cognitive and motor development, yet much of the research on this topic has been conducted in controlled laboratory settings, which may not accurately reflect the diversity of toys and interactions infants experience in their natural environments. This study uniquely examined these interactions in a home setting by utilizing an online video conferencing platform. This study investigated how toy properties influence manual infant-object interactions during dyadic tabletop free play, where mothers selected the toys for the session. Within the confines of this study, results show that infants spend significantly more …

Fast Fashion: Discovering American Consumers' Opinions, Ava Vignola

Florida Atlantic Undergraduate Research Journal

The effects of fast fashion range from human rights violations to environmental devastation. This study uncovers the views of Americans on fast fashion. It was expected to find that many Americans prioritize price when shopping, due to the growth of these companies. The study had 193 people complete a questionnaire on Amazon Turk that contained 16 questions. It found that most Americans consider the price to be more important than the ethics when shopping, with there being a statistically significant difference (p < .001) in that older consumers are more likely to prioritize price. It also found that males are more likely to disagree than females with the statement that fast fashion is unethical (p < .001). This data can be used to create marketing strategies to encourage American consumers to purchase from sustainable companies.

Faculty Publications

Perceptions of the neighbourhood environment can play an important role in promoting public health, yet modifying perceptions is challenging. Adjusting the built environment may be a pathway to influence perceptions. In addition to the physical environment, intrapersonal factors may shape perceptions. This study analysed data from several Japanese major cities to explore the association between objective and perceived neighbourhood environment attributes, stratified by age and gender. Perceived neighbourhood environment measures were adapted from established scales, while objective measures were derived from participants’ geographic address data. Multivariate linear regression was employed to assess these associations. All objective measures were positively associated …

Humidity Control Apparatus And Materials, Ying Zhong

USF Patents

A ventilation port maintains the humidity range within a sealed or partially sealed enclosure maintaining a level of atmospheric moisture such as a greenhouse. The port is comprised of a polymer blend film made of a hydrophilic component serving as the water-absorbing material and substrate component serving as the mechanical backbone. The film is designed to bend and open the port when the humidity within the enclosure exceeds a predetermined level outside the humidity range, allowing for the venting of excess humidity. Once the humidity falls back within the desired range, the film returns to its original state and closes …

Analyzing The Impact Of Passive Techniques On Aircraft Wing Hysteresis: An Experimental And Numerical Study, Brendan Worton

Masters Theses

This study investigates the effects of passive flow control techniques on aerodynamic hysteresis primarily in NACA 2412 (cambered) and 0012 (symmetric) wings. Computational Fluid Dynamics (CFD) was used to design and evaluate three passive techniques, including outward-facing dimples, leading-edge tubercles, and rectangular vortex generators, prior to experimental validation. These techniques demonstrated improvements in aerodynamic performance in CFD simulations and were therefore selected for wind tunnel testing to analyze their aerodynamic performance and influence on hysteresis behavior. A custom, cost-effective experimental setup was designed and developed to facilitate efficient angle-of-attack control and data acquisition. It incorporates a three-axis force sensor, stepper …

Tradition, Critque, And The Modern Moral Lingua Franca: A Lutheran Articulation Of Human Rights Language, Christian B. Dollar

Doctor of Philosophy Dissertation

The language of subjective, individual rights has become the primary way of speaking about the rights and wrongs of human life together. Since the end of World War II, one subset of this language—that of human rights—has achieved a global influence. The various Christian traditions of the west have, in large part, adopted this language of human rights to articulate and supplement their assorted social teachings. Yet, the adoption of human rights language has been contested by a dedicated cadre of Roman Catholic and Protestant theologians concerned about the potentially anti-Christian implications inherent in the grammar of rights. Christian rights …

BACKGROUND: In the FUEL (Fontan Udenafil Exercise Longitudinal) trial, a positive treatment effect was identified for outcomes at the ventilatory anaerobic threshold but not for the primary outcome, oxygen consumption (Vo₂ in participants with near-normal baseline exercise performance.

METHODS: Participants were divided into subgroups by baseline predicted peak Vo₂ (< 80% versus ≥80%). Treatment effect was evaluated in those with a baseline peak Vo2 < 80% predicted and linear regression was performed to examine the interaction between subgroup and response to therapy for the primary and secondary outcomes.

RESULTS: Of the 379 participants with paired exercise data, 302 (80%) had a baseline peak Vo₂ < 80% predicted. In this subgroup, the primary outcome of peak Vo₂ improved significantly after 6 months of udenafil treatment, when compared with placebo (0.23±4.17 mL/kg per min versus -0.90±3.74 mL/kg per min; P=0.021). Secondary outcome measures, including Vo₂ at …

Plant-Microbe Interactions Across Scales: Diversity, Disease, And Stress In Herbaceous Plant Communities, Philippa Tanford

Arts & Sciences Graduate Student Theses and Dissertations

Plants interact consequentially with microbes spanning mutualism to pathogenicity, with broader effects on large-scale plant community structure. These plant communties, in turn, shape below and aboveground microbial communities through a variety of mechanisms. However, plant diversity-microbial diversity relationships remain broadly inconsistent across environments and among different plant and microbial assemblages. In my dissertation, I work to bridge some of these gaps in plant-microbial ecology in three experimental chapters assessing relationships between plant diversity and microbial diversity, including the influence of belowground-aboveground microbiome interactions, the influence of drought stress, and incorporating different spatial and experimental scales. First, I explore the microbial …
