Developing An After-School Program To Increase Stem Interest, Awareness And Knowledge Of Minority Females In A Title I Middle School, Steven R. Terrell Ph.D., Deirdre Krause Ph.D., Bruce G. Campbell Ed.D.
Developing An After-School Program To Increase Stem Interest, Awareness And Knowledge Of Minority Females In A Title I Middle School, Steven R. Terrell Ph.D., Deirdre Krause Ph.D., Bruce G. Campbell Ed.D.
FDLA Journal
Educators, politicians and industry professionals note that the number of opportunities for workers in the science, technology, engineering and math (STEM) fields grow exponentially over time. Accordingly, emphasis is placed on our schools to produce graduates capable of filling these positions. While these efforts are promising, there is a notable absence of females and minorities in the STEM professions. In an attempt to understand the reasons for this disparity, many educators believe a lack of interest in the STEM field begins at an early age, and disenfranchised students are not afforded the opportunities given to students in more affluent areas …
The Potential Of Socio-Biologically Relevant Mobile Applications To Attract Girls To Stem, Vanaja Nethi, Santanu De
The Potential Of Socio-Biologically Relevant Mobile Applications To Attract Girls To Stem, Vanaja Nethi, Santanu De
FDLA Journal
Stimulating girls’ interest in science, technology, engineering and mathematics (STEM) when they are in school, and sustaining that interest, is critical in motivating girls to choose STEM-related disciplines in higher education and enter STEM careers. Research indicates that girls show an interest in STEM until about 11-12 years of age, but this starts to wane by the time they are 15-16 years. Thus, there is a clear need to focus on sustaining the interest of girls in STEM at middle or high school levels. Research has shown that one of the main drivers that impact girls’ interest in STEM is …

Fallen Pillars: The Past, Present, And Future Population Dynamics Of A Rare, Specialist Coral–Algal Symbiosis, Andrea Chan, Cynthia L. Lewis, Karen L. Neely, Iliana B. Baums
Marine & Environmental Sciences Faculty Articles
With ongoing changes in climate, rare and ecologically specialized species are at increased risk of extinction. In sessile foundation fauna that reproduce asexually via fragmentation of existing colonies, the number of colonies does not reflect the number of genets and thus can obscure genotypic diversity. Colonies that are the product of fragmentation are not visually distinguishable from colonies that stem from sexual recruits. For this reason, molecular markers are necessary to assess genotypic variation and population structure in clonal organisms such as reef-building corals and their endosymbiotic dinoflagellates. For the rare Caribbean pillar coral, Dendrogyra cylindrus, and its endosymbiotic …

Generalising From Qualitative Research (Gqr): A New Old Approach, John Guenther, Ian Falk
Generalising From Qualitative Research (Gqr): A New Old Approach, John Guenther, Ian Falk
The Qualitative Report
In this paper, the authors debunk a long-held myth that generalisation is primarily the domain of quantitative research. Based on a review of modern and historical approaches to generalisation, they argue that generalisation from qualitative research (GQR) can be achieved, not through a process of self-justification, but through defensible and rigorous research design and methods. The authors go on to consider examples from their own qualitative research work spanning the last 20 years. From these examples they offer mechanisms that qualitative researchers can employ to generalise from their findings. They suggest that generalisation is achieved through a process of generalisation …

A Review Of The Global Commercial Cephalopod Fishery, With A Focus On Apparent Expansion, Changing Environments, And Management, Corey Clark
HCNSO Student Capstones
Cephalopods are both important predators and prey in many marine environments and important fishery resources in many countries. The global fishery has expanded almost continuously from landings of 580,000 metric tonnes in 1950 to over 4 m.t. in 2007. Cephalopods are ecological opportunists with highly plastic biological characteristics and varied population dynamics. Nearly all commercially harvested species are short-lived and can reproduce quickly, enabling them to evolve more rapidly under high selection pressure relative to many fish competitors and predators. As a result, they may have the biological means to be successful under conditions of long-term global climate change. This …

What Makes A Good Research Consultant?, Justin Harding, Samantha Estrada, Michael Floren
The Qualitative Report
Statistical and research consulting is defined as the collaboration of a statistician or methodologist with another professional for devising solutions to research problems. An in-depth, interview qualitative approach was taken to answer the research question of what makes a good research consultant. The authors interviewed four faculty members in the field of statistics and research methods and two experienced graduate student consultants. In-depth, face-to-face interviews revealed common themes regarding consultancy skills, resourcefulness, communication and interpersonal skills. The participants discussed how to improve consulting sessions and deal with clients with different statistics levels and backgrounds. Participants felt there was no difference …
Nutrient Concentrations And Effects On Mill Run From Residential, Urban, And Industrial Stormwater Contamination, Melissa Carver
Nutrient Concentrations And Effects On Mill Run From Residential, Urban, And Industrial Stormwater Contamination, Melissa Carver
HCNSO Student Theses and Dissertations
Nutrients are introduced into the waters of the Commonwealth of Pennsylvania through various methods, mainly through point and non-point sources. Non-point sources would include agricultural means however, there are often other non-point sources that are often overlooked. Water runoff from stormwater is an important contributor to pollution entering various watersheds. Data was collected at 4 locations (the initial point of reference, residential, urban, and industrial) on Mill Run and 2 locations on Woodcock Creek, through surface water collection methods in dry and wet weather. Nitrate, Nitrite, Total Phosphorus, and Total Nitrogen were among the data collected. Total Phosphorus had an …
Analysis Of "Observer Effect" In Logbook Reporting Accuracy For U.S. Pelagic Longline Fishing Vessels In The Atlantic And Gulf Of Mexico, Thomas J. Morrell
Analysis Of "Observer Effect" In Logbook Reporting Accuracy For U.S. Pelagic Longline Fishing Vessels In The Atlantic And Gulf Of Mexico, Thomas J. Morrell
HCNSO Student Theses and Dissertations
Commercial pelagic longline fishers within the U.S. Atlantic, Gulf of Mexico, and Caribbean are required to report all fishing interactions per each gear deployment to NOAA’s Vessel Logbook Program of the Southeast Fisheries Science Center to quantify bycatch, increase conservation efforts, and avoid jeopardizing the existence of vulnerable species listed under the Endangered Species Act (ESA). To provide additional accuracy, the Pelagic Observer Program (POP) of the SEFSC deploys professionally trained observers on longline vessels to produce a statistically reliable subset of longline fisheries data. A comparison of self-reported (“unobserved”) datasets versus observer-collected (“observed”) datasets showed a general consistency for …

The Sedimentology Of Cay Sal Bank - An Incipiently Drowned Carbonate Platform, Luis Ramirez
The Sedimentology Of Cay Sal Bank - An Incipiently Drowned Carbonate Platform, Luis Ramirez
HCNSO Student Theses and Dissertations
Sediment on Cay Sal Bank (CSB) is characterized by its coarse-grain size, poor sorting, predominance of skeletal fragments, and relatively depleted d18O isotope values. CSB is an incipiently drowned platform in close proximity to the Great Bahama Bank (GBB), a carbonate platform which is not incipiently drowned and characterized by fine-grained, non-skeletal sediment. The GBB has locally well-developed oolitic grainstone facies and coral reef margins, which are both lacking on CSB. Platform-top water depths on the GBB are typically 10 m or less, but CSB depth ranges between 7 and 30 m. CSB is devoid of mud, whereas …
Determining How Risk Effects Predator-Prey Interactions Of Marine Communities In The Nearshore Environment Of South Bimini, The Bahamas, Kendall Brancart
Determining How Risk Effects Predator-Prey Interactions Of Marine Communities In The Nearshore Environment Of South Bimini, The Bahamas, Kendall Brancart
HCNSO Student Theses and Dissertations
Predators often have strong top-down effects on ecosystems and are considered a priority for conservation and management. Predator activity can influence prey distribution, abundance, and foraging behaviors and are likely to influence habitat by impacting ecological and environmental characteristics as well as presence of competitor species. There are knowledge gaps of the functional diversity of fish assemblages, non-consumptive predator effects, and environmental effects on fish assemblages. With this study, effects of top marine predators, such as sharks and great barracuda, on diversity and abundance of prey communities were examined in putative low (north side of South Bimini = lagoon) and …
Assessment Of Heavy Metals In Subsistence-Harvested Alaskan Marine Mammal Body Tissues And Vibrissae, Pilar M. Ferdinando
Assessment Of Heavy Metals In Subsistence-Harvested Alaskan Marine Mammal Body Tissues And Vibrissae, Pilar M. Ferdinando
HCNSO Student Theses and Dissertations
The coastal, indigenous communities around Alaska have subsisted on marine animals for generations, often focusing on large apex predators such as seals, sea lions, and whales. Three species of pinnipeds (harbor seal, Steller sea lion, northern fur seal) and the northern sea otter have all undergone significant population declines since the 1970s, some regions more than others. Archived vibrissae (whiskers) and body tissues from these four species were available from the Bering Sea and throughout the Gulf of Alaska from the 1990s and early 2000s. Tissues from these species are exceedingly difficult to obtain; thus, the archived tissues provided a …
Optimizing Restoration Site Selection Along The Florida Reef Tract For The Coral Species Acropora Cervicornis And Acropora Palmata, Samantha King
Optimizing Restoration Site Selection Along The Florida Reef Tract For The Coral Species Acropora Cervicornis And Acropora Palmata, Samantha King
HCNSO Student Theses and Dissertations
The decline of Acropora cervicornis and Acropora palmata populations and consequent listing as endangered species has prompted the need for restoration. Since financial resources are limited, optimal sites for restoration should not only be environmentally suitable for outplant survival, but also have a greater capacity to replenish surrounding reefs with larvae. However, in Florida coral larval dispersal patterns and reef connectivity remain poorly studied. Here, we measured long term larval survival and competency of A. cervicornis to calibrate a high resolution (100m) biophysical larval dispersal model of Acropora in the Florida Reef Tract (FRT). This model revealed that there is …
Effects Of Deposited Sediment And Turbidity On Survival And Growth Of Orbicella Faveolata Recruits, Morgan Stephenson
Effects Of Deposited Sediment And Turbidity On Survival And Growth Of Orbicella Faveolata Recruits, Morgan Stephenson
HCNSO Student Theses and Dissertations
Corals are frequently exposed to elevated turbidity and deposited sediment caused from coastal construction, dredging, and/or beach renourishment. This study addresses the effects of turbidity and deposited sediment on the survival and growth of newly settled and 6-week-old Orbicella faveolata recruits and disentangles the effects of turbidity and deposited sediment. We conducted two experiments in which newly settled coral recruits were reared in one of ten different turbidity and deposited sediment treatments for five weeks (0 NTU/ 0 mg cm-2, 3.4 NTU/ 0 mg cm-2, 8.2 NTU/ 0 mg cm-2, 16 NTU/ 0 mg …

Indirect Legacy Effects Of An Extreme Climatic Event On A Marine Megafaunal Community, Robert Nowicki, Michael Heithaus, Jordan Thompson, Derek Burkholder, Kirk Gastrich, Aaron Wirsing
Marine & Environmental Sciences Faculty Articles
While extreme climatic events (ECEs) are predicted to become more frequent, reliably predicting their impacts on consumers remains challenging, particularly for large consumers in marine environments. Many studies that do evaluate ECE effects focus primarily on direct effects, though indirect effects can be equally or more important. Here, we investigate the indirect impacts of the 2011 “Ningaloo Niño” marine heatwave ECE on a diverse megafaunal community in Shark Bay, Western Australia. We use an 18‐year community‐level data set before (1998–2010) and after (2012–2015) the heatwave to assess the effects of seagrass loss on the abundance of seven consumer groups: sharks, …
A Comparison Of Circle And J Hook Performance Within The Grenadian Pelagic Longline Fishery, Anthony G. Burns
A Comparison Of Circle And J Hook Performance Within The Grenadian Pelagic Longline Fishery, Anthony G. Burns
HCNSO Student Theses and Dissertations
The development and adaptation of gear technologies to local fisheries has been a management-oriented research strategy commonly used to mitigate the ecological effects of pelagic longline (PLL) gear on bycatch species. Grenada’s PLL fishery primarily targets yellowfin tuna, however while minimal, their bycatch of blue marlin and white marlin exceeds the Total Allowable Catch (TAC) allowed by the International Commission for the Conservation of Atlantic Tunas (ICCAT). A switch to circle hooks may benefit these nontargeted, bycatch species by reducing catch rates and haulback mortality, as well as increasing post-release survival. To determine differences in performance, assessments of 16/0 circle …
Using Cognitive Apprenticeship To Enculturate New Students Into A Qualitative Research, Marisa E. Exter, Iryna Ashby
Using Cognitive Apprenticeship To Enculturate New Students Into A Qualitative Research, Marisa E. Exter, Iryna Ashby
The Qualitative Report
Acquiring and mastering research skills is essential for doctoral students preparing for a future in academia or research-focused positions. However, they are among the most difficult to teach, and significant practice and enculturation is necessary to attain proficiency. The subjective nature of qualitative analysis often leads students to doubt their own abilities. This paper describes how cognitive apprenticeship was paired with Lincoln and Guba’s Constant Comparative Method for Naturalistic Inquiry, using a hands-on, physical card sort approach to mentor a novice qualitative researcher. Steps followed are discussed in detail, and voices of both the mentor and mentee are shared.
So You Want To Do Post-Intentional Phenomenological Research?, Katherine E. Soule, Melissa Freeman
So You Want To Do Post-Intentional Phenomenological Research?, Katherine E. Soule, Melissa Freeman
The Qualitative Report
In this article, phenomenology, both in its philosophical and methodological variants, is introduced in the form of a fictional dialogue between a student justifying her interest in using a post-intentional phenomenological approach in her dissertation to her major professor. The dialogue tackles founding philosophers, notably Husserl, Heidegger, and Merleau-Ponty; contemporary researchers, including A. Giorgi, B. Giorgi, van Manen, and Vagle; several phenomenological concepts, such as intentionality, bracketing, and bridling; and provides examples of three distinct approaches to phenomenological research.

Marine & Environmental Sciences Faculty Articles
With compelling evidence that half the world’s coral reefs have been lost over the last four decades, there is urgent motivation to understand where reefs are located and their health. Without such basic baseline information, it is challenging to mount a response to the reef crisis on the global scale at which it is occurring. To combat this lack of baseline data, the Khaled bin Sultan Living Oceans Foundation embarked on a 10-yr survey of a broad selection of Earth’s remotest reef sites—the Global Reef Expedition. This paper focuses on one output of this expedition, which is meter-resolution seafloor habitat …
Developing Interactive Elicitation: Social Desirability Bias And Capturing Play, Matthew Spokes, Jack Denham
Developing Interactive Elicitation: Social Desirability Bias And Capturing Play, Matthew Spokes, Jack Denham
The Qualitative Report
Drawing on research from a mixed-methods project on gaming we argue for a qualitative methodological approach called “interactive elicitation,” a form of data collection that combines elements of photo elicitation, interviewing and vignettes. After situating our broader research project exploring young people’s experiences of violent open-world video games, we outline the process of conducting interactive elicitation, arguing for a mixed-methods approach where participants are observed and interviewed both during and immediately after interacting with particular cultural artefacts, in this case the game GTA V. We reflect on the initial design of the research methodology, the problematic aspects of conducting the …
The Association Between Stomach Fullness And Vertical Migration Behavior In Deep-Pelagic Crustaceans And Fishes In The Gulf Of Mexico, With Notes On Microplastic Ingestion, Ryan P. Bos
HCNSO Student Theses and Dissertations
This thesis presents: 1) the first statistically rigorous support for the longstanding hypothesis that state of satiation modifies diel vertical migration patterns of deep-sea micronektonic crustaceans and fishes; and, 2) the first assessment of microplastic ingestion by deep-pelagic micronekton in the Gulf of Mexico and Straits of Florida. Deep-sea pelagic crustaceans and fishes significantly contribute to abundance and biomass of pelagic ecosystems, are frequently consumed by commercially valuable fishery species, and serve to transport both nutrients and pollutants between shallow and deep waters. The results presented herein will be valuable for assessing risk associated with potential biomagnification of plastic through …
Assessing Deep-Pelagic Shrimp Biomass To 3000 M In The Atlantic Ocean And Ramifications Of Upscaled Global Biomass, Alexander Vereshchaka, Anastasia Lunina, Tracey Sutton
Assessing Deep-Pelagic Shrimp Biomass To 3000 M In The Atlantic Ocean And Ramifications Of Upscaled Global Biomass, Alexander Vereshchaka, Anastasia Lunina, Tracey Sutton
Marine & Environmental Sciences Faculty Articles
We assess the biomass of deep-pelagic shrimps in the Atlantic Ocean using data collected between 40°N and 40°S. Forty-eight stations were sampled in discrete-depth fashion, including epi- (0–200 m), meso- (200–800/1000 m), upper bathy- (800/1000–1500 m), and lower bathypelagic (1500–3000 m) strata. We compared samples collected from the same area on the same night using obliquely towed trawls and large vertically towed nets and found that shrimp catches from the latter were significantly higher. This suggests that vertical nets are more efficient for biomass assessments, and we report these values here. We further compared day and night samples from the …

Dental health requires regular, preventive care at home as well as professional screenings and interventions. The goal of this research is to examine the current need for dental education for children in poor and rural villages in Gujarat, India. Previous research indicates that children aged of 12-15 have not received proper oral health education. This poster will focus on dental health and hygiene of school aged-children treated at the VAD clinic in Ahwa, Gujarat, India, including an oral health education …
Examining The Antibacterial Properties Of Placental Tissue Components, Sujad Younis
Examining The Antibacterial Properties Of Placental Tissue Components, Sujad Younis
Undergraduate Student Symposium
As the use of antibiotics has increased, the rate of antibiotic resistance has grown leading to a pressure to develop new antibiotics. Placental tissue is known to exhibit antimicrobial activity against bacteria, making it a viable candidate for novel antibiotic development. With this knowledge in hand, various components of placental tissue were tested to determine the portions that exhibited antibacterial activity. Dried placental tissue were micronized and rehydrated. The goal of this project was to take the product and test them on multiple bacterial species, some of which are common to human skin. The bacterial species tested were Escherichia coli …
Human Angiotensinogen Gene Regulation By Hypoxia Inducible Factor - A Cell-Based Study, Sami Ansari, Moiz Khan
Human Angiotensinogen Gene Regulation By Hypoxia Inducible Factor - A Cell-Based Study, Sami Ansari, Moiz Khan
Undergraduate Student Symposium
Alcohol usage is linked to increased blood pressure and fibrotic transformation of the liver after the hepatocyte death. Angiotensinogen (AGT) is the source of Ang II which is produced from AGT by sequential action of renin followed by angiotensin converting enzyme. The blood AGT levels correlate to blood pressure, therefore, an increase in blood AGT levels result into corresponding increase in Ang II levels affecting blood pressure regulation and liver fibrogenic processes. Alcohol metabolism by the liver produces oxidative stress (ROS) that activates hypoxia inducible transcription factor-1alpha (HIF1α). Hepatocytes lose alcohol metabolizing enzymes after passages, therefore HIF-1α mediated activation of …

Undergraduate Student Symposium
In this documentary film, “Am I #MeToo?,” women of three different cultures, religions, and ethnicities will be interviewed regarding their view of the Me Too Movement. I will focus on whether they feel included and/or represented when it comes to modern social movements. The film will also question whether certain communities get left out because of the stereotypes surrounding their identities. The goal of this project is to shed light on which people are actually receiving the help they seek in these social movements. I want to provide an understanding of what empowerment is being sought through these ideologies, and …
Mind Your Thoughts: Individual Differences In Mind Wandering, Chethani Chitraacharige, Catherine Weber, Brianna Thompson, Dayna Jetmore
Mind Your Thoughts: Individual Differences In Mind Wandering, Chethani Chitraacharige, Catherine Weber, Brianna Thompson, Dayna Jetmore
Undergraduate Student Symposium
Mind wandering consumes almost half of our day, while influencing behaviors and activities experienced throughout individuals’ lives (Killingsworth & Gilbert, 2010). The impact of mind wandering on task performance may vary but typically, task performance is impaired when people mind wander (Randall, Oswald, & Beier, 2014). The current study examined predictors of mind wandering in both the laboratory and the real world. New to this study we examined mind wandering across two dimensions: emotional valence and intentionality. To measure mind wandering in the lab, participants completed a sustained attention task with thought probes. Mind wandering in the real world was …
Effect Of Standardizing Kick Plate Position On Track Start Biomechanics In Elite Swimmers, Angela Cicenia, Caroline Oster
Effect Of Standardizing Kick Plate Position On Track Start Biomechanics In Elite Swimmers, Angela Cicenia, Caroline Oster
Undergraduate Student Symposium
In the swimming track start the kick plate position on the starting block is chosen by the level of comfort of the swimmer but may influence performance. Hundredths of a second often determine the winner of short distance races. Therefore, it is crucial for a swimmer to produce a biomechanically sound start. The purpose of this study was to investigate the influence of standardizing kick plate positioning based on shin length on selected biomechanics. 15 swimmers (males, 10; females, 5; age, 21.3 ± 1.7 yrs; height, 1.79 ± 0.08 m; mass, 77.4 ± 10.4 kg) participated in the study. Shin …
