Differential Treatment and Outcomes of Racial and Ethnic Minorities in Psychotherapy

Description: Therapeutic alliance has been consistently demonstrated as a robust predictor of treatment outcomes, though the time in psychotherapy at which therapeutic alliance best predicts outcomes is unclear. Unfortunately, evidence suggests that racial and ethnic minority clients typically form weaker therapeutic alliances in treatment. The weaker development in therapeutic alliance among racial and ethnic minority clients may mediate discrepancies in treatment outcomes, including higher dropout rates. … more

French and Canadian Inclusive Language Doctrine and Societal Attitudes

Description: One of the most important French grammar rules is the rule of superiority: Masculine subjects always trump feminine subjects when there are multiple subjects. Superiority is closely followed by the acceptance that all nouns have a grammatical gender, either masculine or feminine. Since 1984, and over the span of forty years, these rules have been challenged on multiple levels of French society. The research conducted over the course of this thesis focuses on the mentality and reactions of the F… more

How Much Does Sleep Vary from Night to Night? A Quantitative Summary of Intraindividual Variability in Sleep by Age, Gender, and Racial/Ethnic Identity

Description: Habitual (i.e., average or typical) sleep duration and sleep efficiency vary widely by demographic characteristics, including age, gender, and racial/ethnic identity. Despite a wealth of studies on demographic patterns in habitual sleep, these results are often based on cross-sectional surveys, which ask participants to retrospectively recall their "typical" or "recent" sleep. Yet, sleep is a highly dynamic behavior and may fluctuate substantially from night-to-night. This intraindividual varia… more

Diverging Perceptions of Emotional Black and White Female Leaders

Description: Stereotypical beliefs about emotion have been shown to influence perceptions of competence. While emotional White women are often presumed to be generally less competent, emotional Black women receive variable competence ratings due to the intersecting stereotypes concerning both their race and gender. However, it is unclear how perceptions of competence fluctuate in response to anger, a stereotypically male emotion, in comparison to sadness, a stereotypically female emotion. The project at han… more

A Safe and Fast Deworming Procedure for Horses

Description: Most horse owners administer oral deworming medication to their horses on a set schedule, often six times per year. The deworming process involves using a plastic syringe to inject a thick paste into the horse's mouth. Most horse owners do not specifically train their horses to accept this procedure. Consequently, many horses resist the procedure and some horses engage in behaviors, such as head shaking, pulling away, or even rearing, that may be dangerous to humans or to themselves. This study… more

The Intersection of Race and Space in Urban Environments Confronting Development: The Black Church and Harlem's Gentrification

Description: Roughly 1 million Blacks fled from the South to cities in the North, and with this shift New York City saw a 66% increase in its Black population between 1910 and 1920. By the end of the 1920s Harlem had become home to approximately 200,000 Black residents. But during the period 2000 to 2016 three of the nation's top ten gentrifying zip codes could be found in Harlem, and Harlem's Black population decreased by 23,166 residents, while Harlem's white population increased by 33,442 during this er… more

Nanolithographic Approaches to Probing Cell Membrane Modulation

Description: Metastatic cancer is more dangerous and difficult to treat than pre-metastatic cancer. Ninety percent of cancer-related deaths are caused by metastatic cancer. When cells go through metastases, they go through changes that allow them to break away from the primary tumor and invade secondary tissues. These changes, in lipid membrane composition and cellular glycocalyx, make the cell more resistant to therapeutics. Actin cytoskeleton contractility plays a major role in these changes, as increased… more

Notch Filter Design for Power Line Interference Artifact Reduction of ECG Signal and Feature Extraction in LabVIEW

Description: Electrocardiogram (ECG) is a biological signal that represents the heart's electrical activity. Interference from power lines introduces a frequency component of 50 to 60 Hz into the signal, which is the principal cause of ECG corruption. By using the Cadence Virtuoso Spectre circuit simulator and typical TSMC RF 180 nm CMOS technology, a notch filter was created to reduce powerline interference. The advantage of utilizing a notch filter for PLI is that noise at 60 Hz is completely eliminated w… more

An Analysis of Compressive Sensing and the Electrocardiogram

Description: As technology has advanced, data has become more and more important. The more breakthroughs are achieved, the more data is needed to support them. As a result, more storage is required in the system's memory. Compression is therefore required. Before it can be stored, the data must be compressed. To ensure that information is not lost, efficient compression is necessary. This also makes sure that there is no redundancy in the data that is being kept and stored. Compressive sensing has emerged a… more

Prisoner's Dilemma in Quantum Perspective

Description: It is known that quantum strategies change the range of possible payoffs for the players in the prisoner's dilemma. In this paper, we examine the effect of the degree of entanglement in determining the payoffs. When both players play quantum strategies, we show that the payoff for both players is unaffected by the entanglement value and it leads to a new Nash equilibrium.

On the Precipice: Examining Generic Convention and Innovation in Thermidorian Opera through "Sapho" (1794)

Description: Often neglected in the musicological coverage of revolutionary music and theater, the Thermidorean Reaction phase (1794–1795) of the French Revolution was a period of governmental transition, in which Parisian theaters enjoyed the institutional and generic freedoms of the Le Chapelier Laws of 1791 in addition to relaxed enforcement of censorship. In recent years, Mark Darlow and Julia Doe's work has advanced understandings of operatic genres during the early years of the Revolution, which they … more
