The role of reactance and positive emotions in persuasive health messages: refining the theory of psychological reactance and the politeness theory and testing the theories of positive emotions
… psychological reactance as a function of threats to positive identity above and beyond threats to freedom and 2) by examining the role of positive emotions. An online survey recruited 478 students from undergraduate courses at several universities in the U.S. The study included a 2 (high …

When worldviews collide: the role of emotion in reactions to symbolic threats.
… challenges to their cherished values--symbolic threats--shape social attitudes. I argue that people respond with distinct emotions depending on whether the symbolic threat comes from within their ingroup or from outsiders, and that these emotions explain why those who feel that their cultural …

Testing Revonsuo's Threat simulation theory of dreaming
Revonsuo's Threat Simulation Theory of dreaming asserts that dreaming was selected during human evolution because it has the adaptive function of providing a threat-free context in which threat perception and avoidance can be rehearsed. This study aimed to test the prediction that the threat …

Privacy vs. Security: Fear appeals, terrorism and the willingness to allow increased government surveillance
… from intrusions by the government. However, the threat of terrorism is also very real. There are indications that some people may be willing to allow intrusion by the government if it means keeping them safe. This study uses an experimental method to determine whether the fear of terrorism is …

An Injury-Based Approach to Quantify the Predictability and Time Sensitivity of Common Motor Vehicle Crash Injuries
… is associated with injuries which have a high mortality and high threat-to-life. Predictability is associated with injuries which are identifiable by emergency medical personnel upon arrival at the scene. Predictable injuries were scored based on an analysis of occult injuries and an …

Response of the Ozark Zigzag Salamander (Plethodon Angusticlavius) to High and Low Level Threats
… (Plethodon angusticlavius) under low and high levels of threat. I predicted that the salamander would specialize on the most profitable prey type under low levels of threat but would forage randomly under high threat. Salamanders in the blank treatment did not specialize on high-calorie …

Mathematics anxiety and women : cognitive, motoric and physiological dimensions
… math tasks. While performing these two tasks, high threat and low threat, heart rate, self-reported anxiety and motoric performance were monitored. Data were collected before and after each specific task. Data were also collected at pre-selected points during the task performance. This …

Model Predictive Control for Autonomous Landing in Complex Scenarios
… helicopter to ensure the safety of soldiers in high threat or altogether dangerous scenarios. In this thesis model predictive control (MPC) algorithms are developed to enable a quadcopter to operate and land autonomously in challenging environments. Specifically, MPC entails repeatedly solving …

Life history trade-offs in a parental care-providing fish: the role of reproductive value, predation threat, and physiological condition on brood abandonment decisions by paternal largemouth bass
… brood-guarding paternal largemouth bass, and the threat of brood depredation (i.e., brood predator density), on brood abandonment decisions. Together, my results suggested a threshold for brood loss at which paternal largemouth bass were more likely to abandon what remains of a depredated brood, …

A margin-based approach to vehicle threat assessment in a homotopy framework for semi-autonomous highway navigation
… describes the design of an unified framework for threat assessment and the shared control between a human driver and the onboard controller, based on the notion of fields of safe travel. It allows to perform corridor navigation, trajectory planning, threat assessment and driving assistance in …

Behavioral and Physiological Ecology of Scorpion Venom Expenditure: Stinging, Spraying, and Venom Regeneration
… volume of venom injected, delivering more during high-threat than low-threat conditions. By metering volume, they also vary the composition of the venom, injecting either clear (potassium-rich) "prevenom" or milky (protein-rich) "venom." The milky venom is ejected only after the limited quantity …
