Hypermasculine, Antifeminine: The Role Of Masculine Identity In Relational Aggression Among Gay Men, Daniel Locke Deason

Dissertations

Relational aggression is a form of aggression that targets a victim’s relationships or sense of inclusion. Depression, social ostracism, anxiety, and poor psychological adjustment are some of the negative correlates that have been identified in child and adolescent victims of relational aggression. For older adolescents and emerging adults, similar negative correlates have been found. Despite the efforts to identify these correlates, little research has been conducted on relational aggression among minority groups. The present study addressed relational aggression among college-aged gay-identifying men through the lens of Exclusively Masculine Identity Theory (EMIT), which was developed to account for anti-gay attitudes among …

Effects Of Historical Story Telling On Student Understanding Of Nos And Mendelian Genetics, Cody Tyler Williams

Dissertations

Science education researchers have long advocated the central role of the nature of science (NOS) for our understanding of scientific literacy. NOS is often interpreted narrowly to refer to a host of epistemological claims associated with the process of science and the limitations of scientific knowledge. Despite its importance, practitioners and researchers alike acknowledge that students have difficulty learning NOS and that this in part reflects how difficult it is to teach. Many teachers are uncomfortable with taking time away from traditional science content instruction. One promising method for teaching NOS and science content involves an explicit and reflective approach …

Sex Differences In Serotonergic And Dopaminergic Mediation Of Lsd Discrimination In Rats, Keli A. Herr

Dissertations

After decades of opposition, a resurgence of interest in the psychotherapeutic potential of LSD is gaining acceptance in the medical community. Future acceptance of LSD as a psychotherapeutic adjuvant may be predicated on knowledge about its neural mechanisms of action. Preclinical drug discrimination assay offers an invaluable model to determine the neural mechanisms underlying LSD’s interoceptive stimulus effects. Unfortunately, current preclinical literature on LSD discrimination is based on results obtained exclusively in male subjects. The present study represents the first known preclinical assessment of possible sex differences in the discriminative stimulus effects of LSD.

Employing Multivariate Logistic Regression Analysis To Better Understand The Relationship Between Individuals’ Anthropogenic Climate Change Acceptance And Belief In Anti-Climate Change Dissenter Messages, Andrew Phillip Keller Bentley

Dissertations

Organized climate change dissention groups spend a considerable amount of time and energy developing messages designed to convince the public that anthropogenic climate change is neither a reality nor a threat. These messages work against the efforts of climate educators and can be divided into two categories; messages that provide alternative explanations for warming, or messages that attack the work of scientists studying anthropogenic climate change. There has been a lack of research regarding any correlation between individuals’ agreement with these messages and their rejection of anthropogenic climate change. Establishing a correlation would be an indication that educators should take …

The Prevalence Of Religious Service Attendance In America: A Review And Meta-Analysis, Chad S. Briggs

Dissertations

The Gallup Poll and General Social Survey have asked Americans about their religious service attendance since 1939 and 1972, respectively. With remarkable consistency, these two surveys have estimated that just over 40% of the American population regularly attends religious services. Yet, recent research has called this “gold standard” into question, citing three sources of bias in these estimates: (a) ambiguous item wording, (b) an ambiguously specified time frame; and (c) data collection methods that lend themselves to socially desirable responding. Several lines of research have developed to eliminate or minimize these sources of bias, but these efforts have yielded a …
