Determining accurate elevations is important for many engineering and scientific applications, and finding these heights via GNSS increases efficiency and significantly reduces the costs as compared to precise geodetic leveling. The National Geodetic Survey (NGS) has published guidelines for determining both ellipsoidal and orthometric heights with GPS to within 2...
As laws regarding medical and recreational cannabis use are changing across the United States, one must begin to understand the effects among individuals with chronic pain. Specifically, it is unclear how legalization may change their use of marijuana and opioids to self-medicate or for recreational use. To address these questions,...
Through the use of daily online surveys, this study investigated the weekly trends associated with college binge drinking. It also investigated the relationship between personality risk factors and binge drinking. Personality risk factors were assessed using the TCI measures of novelty seeking and harm avoidance, and the ATQ measure of...
Mental health issues such as depression are increasingly prevalent in college students. However, research on disparities in mental health problems in students of color in college has been limited. In the present study, we used the Healthy Minds Study (HMS) data collected on mental health of college students from 2018-2019...
Background: Individuals rapidly infer character traits and behaviors through the process of facial perception. Perceptions of trustworthiness, accurate or not, completed by authorities in the criminal justice system may have implications for individuals suspected of crimes, including harsher or longer sentencing decisions. Objective: The present study concerned how the presence...
Background. Flourishing is negatively related with depression, but has been proposed as a separate axis and an independent aspect of overall mental health. One factor that has been shown to affect both depression and flourishing is racial discrimination. This study hypothesizes that, in young undergraduate women of color, discrimination experiences...
Free / Open Source Software developers come from a myriad of different backgrounds. While some contribute for personal reasons, many become involved because they receive compensation from corporations or foundations. The motivation for participating in a project can have dramatic impacts on how and what contribution an individual makes. These...
A wide range of environmental and physiological factors influence the type and extent of sexual dimorphism found in animals. Influential factors include variable climate, competition for resources and mates, mate choice, and parental investment. In addition, some investigators attribute differences in body size to physiological factors influenced by genetic and...
Many species have complex life cycles in which a dispersive larval stage is
followed by a relatively sedentary adult stage. For such species, reproductive output
is often high and large variation in survivorship throughout early life-history phases
(eggs and larvae) can lead to dramatic fluctuations in recruitment which may in...
