Book Review: Kings, Conquerors, Psychopaths: From Alexander To Hitler To The Corporation, Tim Bakken

Genocide Studies and Prevention: An International Journal

The book Kings, Conquerors, Psychopaths is a survey of a vast amount of human wrongdoing. It lays bare the motivations of aggressors who wish to subjugate nations or groups of people and corporate executives and government bureaucrats who make discretionary decisions that harm people. Along with cataloging mass killings by despots and soldiers, the book includes stories about Ponzi-schemers and the deaths of automobile drivers and passengers who were killed by vehicle defects known to the manufacturer. The book posits that “[p]owerful, elite forces are trying to force us backward toward a non-democratic state, one where power, wealth, and prerogative …

Making The Error Bar Overlap Myth A Reality: Comparative Confidence Intervals, Frank S. Corotto

Georgia Journal of Science

Many interpret error bars to mean that if they do not overlap the difference is statistically “significant”. This overlap rule is really an overlap myth; the rule does not hold true for any conventional type of error bar. There are rules of thumb for estimating P values, but it would be better to show error bars for which the overlap rule holds true. Here I explain how to calculate comparative confidence intervals which, when plotted as error bars, let us judge significance based on overlap or separation. Others have published on these intervals (the mathematical basis goes back to John …

Playful Mouth-To-Mouth Interactions Of Belugas (Delphinapterus Leucas) In Managed Care, Jackson R. Ham, Malin K. Lilley, Riley J. Winchenski, Jesus Miranda, Ángel G. Velarde Dediós, Katie Kolodziej, Sergio M. Pellis, Heather M. Manitzas Hill

All Faculty Scholarship

Belugas (Delphinapterus leucas) engage in many forms of play (e.g., object, water, locomotor), but no play is quite as curious as the unusual form of cooperative social play involving mouth-to-mouth interactions. These playful interactions are characterized by two belugas approaching each other head-to-head and interlocking their jaws, clasping one another, as if they were shaking hands. Observed in belugas both in the wild and in managed care, it is seemingly an important type of social play that offers a unique way of socializing with conspecifics. To describe this unusual behavior, a group of belugas in managed care was …

Sleep Duration Is Associated With Caudate Volume And Executive Function, Nicole Jones

Honors Theses

The ineligible role of the caudate nucleus in sleep has been implicated throughout multiple scientific studies. Previous literature has shown that greater caudate volume is associated with longer habitual sleep duration in older adults- ranging from 55 years of age and up. However, the association between sleep duration and caudate volume remains unknown in the younger population. In this study, we examined the caudate volume in youth to older adults (10 to 85 years old) with a greater sample size (N=464) to increase statistical power. The volumetric size of the caudate nucleus showed significantly positive association with habitual sleep duration, …

A Deeper Understanding Of Noise Effects On Cetaceans, Jason N. Bruck

Faculty Publications

Recent research with cetaceans under human care is illuminating just how dolphins are affected by human-made noise both in terms of their ability to cooperate as well as their ability to habituate to such noise. This research is providing granular detail to regulators assessing the problems associated with anthropogenic effects and is highlighting a role for behavior/cognition research in conservation.

A Quieter Ocean: Experimentally Derived Differences In Attentive Responses Of Tursiops Truncatus To Anthropogenic Noise Playbacks Before And During The Covid-19-Related Anthropause, Paige E. Stevens, Veda Allen, Jason N. Bruck

Faculty Publications

The effects of anthropogenic noise continue to threaten marine fauna, yet the impacts of human-produced sound on the broad aspects of cognition in marine mammals remain relatively understudied. The shutdown of non-essential activities due to the COVID-19-related anthropause created an opportunity to determine if reducing levels of oceanic anthropogenic noise on cetaceans affected processes of sensitization and habituation for common human-made sounds in an experimental setting. Dolphins at Dolphin Quest Bermuda were presented with three noises related to human activities (cruise ship, personal watercraft, and Navy low-frequency active sonar) both in 2018 and again during the anthropause in 2021 via …

College Students' Relationship With Attention Deficit Hyperactivity Disorder And Learning Accommodations At The University Of Nebraska-Lincoln, Brianna Danehey, Kim Hansen Dr., Chelsea Witt Dr.

Honors Theses

Attention deficit hyperactivity disorder (ADHD) can provide many challenges for college students due to difficulties focusing, multi-tasking, and staying organized. Colleges are required to offer academic accommodations to students with disabilities in an attempt to provide students with an equitable learning environment. However, accommodations may be ineffective if they are highly unattainable, unused by the student once granted, or hindered by university faculty.

The objective of this study was to identify barriers to receiving effective and beneficial academic accommodations for individuals with ADHD at the University level and to provide insight into college students' knowledge and relationships relating to the …

Comparison Of General Population Vs. U.S. Military Veterans Eating Disorder Prevalence, Micah Callahan

University Honors Theses

Eating disorders disrupt the psychological wellbeing, work ability and daily functioning of many individuals. There is currently no data to compare the prevalence of eating disorders in the general public compared to the military population. The hypothesis was that the military population would be significantly higher in prevalence compared to the general population within the general eating disorder, subcategories of eating disorders and between sex. To analyze the data collected from two studies, sixteen two-proportion Z tests were conducted to determine if the proportions of DSM-V eating disorders differed within and between sex for total incidence and sub-category incidence for …
