Are you my baby? Testing whether paternity affects behavior of cobreeder male acorn woodpeckers

Walter Koenig, Joseph Haydock, Hannah Dugdale & Eric Walters
Natural selection is expected to favor males that invest more in offspring they sire. We investigated the relationship between paternity and male behavior in the acorn woodpecker (Melanerpes formicivorus), cooperative breeders that live in family groups including offspring that remain on their natal territory, sometimes for years, and cobreeders of both sexes. Regardless of group composition, only one communal nest is attended at a time. Whereas cobreeding females share maternity equally, one male often sires...

Quantifying capital vs. income breeding: new promise with stable isotope measurements of individual amino acids

John Whiteman
1. Capital breeders accumulate nutrients prior to egg development, then use these stores to support offspring. In contrast, income breeders rely on local nutrients consumed contemporaneously with offspring development. Understanding such nutrient allocations is critical to assessing wildlife reliance on different habitats. 2. Despite the contrast between these strategies, it remains challenging to trace nutrients from endogenous stores or exogenous food intake into offspring. Here, we tested a new solution to this problem. 3. Using...

The second is a governance concern due to the challenges involved in managing future interactions between the firm and its...

The Impacts of Surface Gravity Waves on Buoyant Plume Dilution

Bruce William Husselbee
A common practice in coastal areas is to collect, treat and discharge fluids including treated wastewater, stormwater or power plant effluent to areas of lesser impact. The discharge of these fluids, conveyed through pipelines into coastal areas, continues to be an important human health and environmental concern. The fluid discharged from these pipelines is often buoyant which allows for dilution and dispersion into these ambient waters. Initial dilution, defined as the maximum concentration of a...

Experiences in Physical Education and Sport: The Intersection of Identifying as a Female, an Athlete, and Visually Impaired

Margaret Buckley
Introduction. Individuals with visual impairments, females, and athletes encounter different challenges during physical education. However, little is known about how the challenges connected with each of these identities intersect and if that intersection impacts experiences differently. The purpose of this study was to take an explicitly intersectional approach to understand how identifying as an individual with a visual impairment, a female, and an athlete intersect to influence physical education and sport experiences.

Rotorcraft Blade Angle Calibration Methods

Brian David Calvert Jr.
The most vital system of a rotorcraft is the rotor system due to its effects on the overall flight quality of the vehicle. Therefore, it is of importance to be able to accurately determine blade position during flight so that fine adjustments can be made to ensure a safe and efficient flight. In this study, a current calibration method focusing on the pitch, flap, and lead-lag blade angles is analyzed and found to have larger...

Diatom Community Composition Shifts Driven by Coherent Cyclonic Mesoscale Eddies in the California Current System

Zuzanna Maria Abdala
The California Current System (CCS) is characterized by an equatorward flowing eastern boundary current, as well as seasonal wind-driven coastal upwelling which supplies nutrient-rich waters to the surface and drives high coastal productivity. Cyclonic mesoscale eddies form off the coast in the CCS where they trap the highly productive upwelled coastal waters, along with their resident planktonic communities, and transport them offshore into the more oligotrophic California Current waters. The interaction between waters within and...

Simulation and Development of the Radial Time Projection Chamber for the BONuS12 experiment in CLAS12

Nathan M. Dzbenski
Knowledge of the structure of nucleons (i:e: protons and neutrons) is a central topic of interest to nuclear/particle physicists. Much more is known about the structure of the proton than the neutron due to the lack of high-density free neutron targets. The Barely Off-shell Nucleon Structure experiment (BONuS12) at Jefferson Lab (JLab) is a second generation experiment upgraded/optimized to advance our knowledge of the neutron's structure using the deep-inelastic scattering of electrons off deuterium. Typically,...

Can Nanotechnology be the Leading Method in Detecting and Treating Cerebral Tumors?

Daniel D. Singh & Zuri Jules-Culver
Nanotechnology refers to the manipulation or design of materials and structures with desired features in the 1nm–1000 nm size range. The blood brain barrier (BBB) is a major obstacle that drugs must overcome in order to reach tumor cells. The role of this barrier is to transport essential nutrients while protecting and regulating the internal environment. Nanoparticles have been shown to transport drugs through this barrier and accumulate in tumor cells. This is significant since...

It’s Elementary: The Bayeux Tapestry as a Medieval Educational Tool

Sarah Bulger
The Bayeux Tapestry, a 230-foot-long, 950-year-old Anglo-Norman embroidery has baffled historians resulting in extensive (and diverse) scholarship since its rediscovery in the eighteenth century. The Bayeux Tapestry plays a preeminent role (outside of contemporaneous manuscripts and texts) in deciphering aspects of medieval life in England through its visual representation of the age of the Norman Conquest. Long-standing assumptions about the Bayeux Tapestry’s commission, production, and purpose have accumulated through the years based on a single...

Auschwitz-Birkenau: A Memorial

Nichole Delasalas
In the 1940s, Nazi Germany was an unstoppable force spreading throughout Europe. Hitler’s agenda was to take control of Europe and make it part of his pure Aryan race. As a result of his actions and his “final solution”, many people suffered. The concentration camp of Auschwitz I was created out of an old Polish military compound for three main reasons. The first was to incarcerate real and perceived enemies of the Nazi regime and...

Reflective Insight: \"Emotional Metamorphosis\"

Robert Melatti
My professor asks: After seeing Auschwitz, how I continue on? How has going there affected me? Starting with the second question first, perhaps the essence of the answer could be found in a comment that Cali, my granddaughter made to her grandmother a couple of days ago. “Grandpa seems sad since he came back from his trip,” she exclaimed. I really had not noticed any change and assumed that any uneasiness in my disposition had...

Reflective Insight: \"Lessons Learned\"

Stephanie Walters
After returning from my study abroad experience, many people have asked me how was the trip? What did you experience? Was it fun? Not many people asked me what I learned, or how I felt. The emotions and knowledge that I have encountered on this trip is a complex subject to grapple with. The Holocaust, or Shoah as Europeans call it, was a tragedy that devastated millions of families. I often thought what would I...
