Countermovement Jump Height as an Indicator of Sprint Performance in Female Division 2 Track and Field Athletes

This study explores indicators of sprinting ability in Division 2 female Track and Field athletes, while also suggesting a protocol for athlete monitoring within the sport of Track and Field. Statistical analysis resulted in significant use of vertical jump height for predicting 10- and 40-meter sprint performances.

Fathers, Friends, And Food: Adult Relationship Attachment Style Predicts Disordered Eating Attitudes

The purpose of the present study was to identify the presence of behaviors indicative of a potential eating disorder, and correlate these behaviors with both the individual’s self esteem scores and relationship attachment style patterns in a variety of close relationships.

Every Drop Counts: Positive Reinforcement in Increasing Hand Hygiene

Hand hygiene compliance has shown to be low in both the healthcare and public setting. This study evaluates the rates of hand hygiene compliance of a regular hand sanitizer dispenser to one with a positive reinforcement visual usage count. Each machine was individually observed for cafeteria visitor's hand hygiene usage or refusal.


The Effect of Live Music as an Intervention on Antepartum Patients

This project examines the effect of playing live, violin music at the bedside of high-risk pregnant patients staying in the Perinatal Special Care Unit at Sharp Mary Birch Hospital for Women and Newborns. Before and after the music session, blood pressure, heart rate and mean arterial pressure were measured.


Effects of Strength-Based Development on Resilience in Undergraduate Nursing Students

The Significance of Comprehensive Sex Education in Relation to Sexual Health at a Private Christian University

STIs are increasing in the U.S., particularly among college-age students.

A Comprehensive Review of Maternal Mortality Rates in the United States and Other Developed Nations

Maternal mortality rates are a reflection of the overall health and quality of healthcare within a country. While the majority of developed countries have seen a decrease in maternal mortality rates over the past few decades, the United States has seen an increase in rates.


Effects of Pelvic Rotation, Trunk Rotation, Ground Reaction Force on Bat Speed in Collegiate Baseball Hitters

Although much research exists on baseball pitching, there is limited research on baseball hitting to show what factors can best predict bat speed. Using 3D Motion Capture, this study shows how stance leg impulse (force x time) predicts pelvic velocity, and angular bat speed, trunk rotation (X factor), and stride length explain bat speed.
