Understanding Fourth Graders' Decline in Reading Motivation from Students' and Teachers' Perspectives

Christine A. Hebert
Previous research by Chall and Jacobs (2003) documented the phenomena of the fourth grade slump, a period in which students switch from learning to read to reading to learn and the subsequent loss of motivation to read. The purpose of this research is to present a phenomenological qualitative study of whether a sample of fourth grade students, low-achieving readers and average achieving readers, exhibited a loss in their motivation to read. Students' responses to a...

Caste, Desire, and the Representation of the Gendered Other in U. R. Ananthamurthy's “Samskara,” “Ghatashraddha,” and “Akkayya”

Krishna Manavalli
U.R. Ananthamurthy is an important Kannada writer who is situated in the navya (modern) literary movement that emerged in Karnataka in the post-independence South Indian context. This modern writer's works provide crucial insights into the postcolonial tensions of tradition-modernity, which figure importantly in modern Kannada literature. They engage with the issues of caste and gender in terms of the conflict between tradition and progress in the modern South Indian cultural discourse. Ananthamurthy's novel Samskara written...

In the United States, the number of dual career couples has been increasing due to economic and personal growth needs (Pixley, 2009). Furthermore, more careers are requiring specialized education than before (O'Neill & Thomson, 2013). However, there is a limited understanding of the trailing career oriented military spouse as a student population (Gleiman & Swearengen, 2012). This phenomenological qualitative study aimed to explore the lived experiences of 11 military spouses pursuing education to advance their...

Nutrient Controls Over Cyanobacterial Synthesis of the Neurotoxin β-N-Methylamino-L-Alanine (BMAA) and Its Potential Accumulation in the Blue Crab (Callinectes Sapidus)

Madeline M. Hummel
Cyanobacteria are known to produce a variety of toxins that negatively impact both aquatic and terrestrial organisms. One putative neurotoxic compound is the non-protein amino acid β-N-methylamino-L-alanine (BMAA), which has epidemiological linkages to the development of several human neurological diseases. Three cyanobacterial species thought to produce BMAA —Microcystis aeruginosa, Synechococcus bacillaris, and Nostoc sp. —were grown in nutrient replete cultures to examine its synthesis and cellular distribution over a growth cycle. Production of BMAA was...

The Messy Nuclear Landscape: Using Fuzzy Cognitive Mapping to Explore Plausible Nuclear Disarmament Scenarios

Ryan M. Nixon
Nuclear weapons are seemingly permanent fixtures in international relations. Although nuclear abolitionists and actors within the Nonproliferation Treaty (NPT) and the International Atomic Energy Agency (IAEA) have taken significant steps towards designing a world without nuclear weapons, the longstanding realist logic that suggests nuclear disarmament is nonviable has born more fruit. On the other hand, some proponents of realism have suggested global nuclear disarmament is feasible, given that certain international instabilities are stabilized and that...

In Hot Water: Thermal Acclimation is Insufficient to Save Corals in the Anthropocene

Harmony Alise Martel
Scleractinian corals are animal partners in exquisite symbioses with a suite of algal, microbial, fungal and viral associates comprising miniature ecosystems collectively referred to as a holobiont. In recent decades, ocean warming has jeopardized the delicate balance of the very symbioses that have enabled coral survival. Thermal stress causes a reduction of algal symbionts, a phenomenon referred to as ‘coral bleaching’ that represents dysbiosis in the holobiont and often leads to mortality. Current thermal acclimation...

The Effects of Automation Transparency and Reliability on Task Shedding and Operator Trust

William Everett Lehman
Because automation use is common in many domains, understanding how to design it to optimize human-automation system performance is vital. Well-calibrated trust ensures good performance when using imperfect automation. Two factors that may jointly affect trust calibration are automation transparency and perceived reliability. Transparency information that explains automated processes and analyses to the operator may help the operator choose appropriate times to shed task control to automation. Because operator trust is positively correlated with automation...

Conceptualization of Faculty Work Motivation: Overcoming the Impasse

Julie Nikolaeva Thompson
The work motivation literature is at an impasse. At the same time, changing economic and social conditions necessitate an ongoing transformation for how organizations motivate their workforce. Although changes in the nature of work have captured the attention of researchers, calls for more research to further develop work motivation theory have largely gone unnoticed. The scarcity of new theoretical research contributes to a lack of contextual understanding in work motivation. As such, organizational leaders continue...

Adding Soul to the Message: Applying African American Jeremiad Rhetoric as Culturally Competent Health Communication Online

Wilbert Francisco LaVeist
This study examines whether online health communications targeting African Americans could be more effective by structuring the message in the format of African American jeremiad rhetoric, a culturally unique version of the American jeremiad literary form. Health disparities (also known as health inequality) persist among African Americans despite increased health knowledge, improved communication practices, and access to health facts online. The problem is systemic, and thus a predictable outcome that requires change in societal structures...

Deep Reinforcement Learning Approach for Lagrangian Control: Improving Freeway Bottleneck Throughput Via Variable Speed Limit

Reza Vatani Nezafat
Connected vehicles (CVs) will enable new applications to improve traffic flow. The focus of this dissertation is to investigate how reinforcement learning (RL) control for the variable speed limit (VSL) through CVs can be generalized to improve traffic flow at different freeway bottlenecks. Three different bottlenecks are investigated: A sag curve, where the gradient changes from negative to positive values causes a reduction in the roadway capacity and congestion; a lane reduction, where three lanes...

Operation Bumpy Road: The Role of Admiral Arleigh Burke and the U.S. Navy in the Bay of Pigs Invasion

John P. Madden
The Bay of Pigs invasion in April 1961 was a political and military fiasco. President John F. Kennedy inherited the plan when he took office in January 1961. Even though there was a low probability of success, Kennedy still approved the operation. Because of the failure at the Bay of Pigs Kennedy lost faith in the Central Intelligence Agency (CIA) and the Joint Chiefs of Staff (JCS). Admiral Arleigh Burke, Chief of Naval Operations (CNO),...

Spire and Tower: The History, Architecture and Art of Two Norfolk, Virginia Churches

Judith L. Smith
While St. Mary of the Immaculate Conception Roman Catholic Church and Epworth Methodist Episcopal Church are dissimilar in origin, religious practices, and architectural style, when taken together, their periods of construction in their respective revival styles span and define an important era in Norfolk, Virginia's urban history. Original research in the sparse records of several Catholic parishes identifies the previously known name of the architect of St. Mary's church. The study also offers additional information...

The Adams Image in American History

Mary Helen McCoy
John Adams was an American Revolutionary leader, political theorist, diplomat, constitutionalist, vice-president, and president. His historical image, however, has not been consistent with his importance in American history. Controversial throughout his lifetime, the Adams image, since his death has been at times obscure, often negative, and seldom positive. Adams had a fear of posterity's perception of his life. Until recent years this fear was confirmed by his historical treatment. This thesis considers the divergence in...

Depositional and Diagenetic History of the Middle Ordovician Carbonates of the Shenandoah Valley, Northern Virginia

Lynn Ellen Weyenberg
An examination of the Middle Ordovician carbonates in northwest Virginia has revealed a particularly sensitive record of deposition and subsidence. Two-hundred acetate peels from six measured stratigraphic sections in Shenandoah County, Virginia were examined to interpret the depositional and diagenetic history. Two major lithofacies have been recognized within the New Market Limestone and three have been recognized in the Lincolnshire Formation. These five lithofacies represent an overall transgressive sequence. This transgression was not uniform but...

Sedimentologic and Stratigraphic Significance of Boulder Layers in the Outer Coastal Plain of Southeastern Virginia

Robert C. McDaniel
In southeastern Virginia one to two discontinuous boulder layers occur at the base of the Pleistocene Norfolk Formation. The sediments, heavy minerals and microfossils within the boulder layers in addition to boulder lithologies, dimensions and orientations were studied to determine the origin of these layers. These data indicate the boulder layers were separated into two similar yet distinct layers. The ancestral James River with sea-level 100 meters lower than today probably had the capacity to...
