Magnetic Field Frequency-Response For Human Magnetophosphene Perception And Associated Eeg Modulations, Cadence M. Baker

Electronic Thesis and Dissertation Repository

Background: Magnetophosphenes are among the most reliably reported effects resulting from magnetic induction. The frequency dependence of the perception threshold is crucial, as guideline agencies use this information to set exposure limits whose purpose is to protect public and workers.

Objective:Establish the magnetophosphene perception thresholds throughout the extremely low frequency range (0-300 Hz) and evaluate the use of EEG as a biomarker.

Hypothesis:Perception thresholds will be lowest at ~30 Hz. EEG occipital alpha power will decrease upon perception.

Methods:60 participants were exposed to homogenous magnetic fields up to 300 Hz, and 70 mT. EEG alpha power …

Cardiodynamic Associations With Resilience In Undergraduate Students And The Effect Of A Mentorship Intervention, Rachel J. Knetsch

Electronic Thesis and Dissertation Repository

The National College Health Assessment (NCHA) indicates that a majority of Canadian university students report feeling overwhelmed, stressed, and anxious during their undergraduate studies. Resilience refers to positive adaptation, or the ability to maintain or regain mental health, despite experiencing adversity (Herrman et al., 2011). While autonomic indices have been used to describe chronic physiological stress, the role of heart rate variability (HRV) as an index of resilience remains unclear. This research tested the hypotheses that (1) there is a relationship between HRV and resilience scoresand (2) a mentorship intervention will improve HRV and resilience outcomes. Fifty-seven first year students …

Pilot Study: Heart Rate Variability Analysis And Mental Health Outcomes In University Female Hockey Players, Kaitlyn Jacobs

Electronic Thesis and Dissertation Repository

Exercise improves anxiety and depression, both of which are associated with impaired autonomic regulation of heart rate (HR). In turn, HR variability (HRV) is a reliable physiological indicator of external stressors. The following research tested the hypothesis that HRV is indicative of chronic resilience towards mental stress in female varsity hockey players. Seventeen varsity hockey players (HOCK, age 21 ± 1.5) and fifteen healthy controls (CTRL, age 21 ± 2.2) at Western University participated three times throughout a 7-month season. Participants completed questionnaires (brief resilience scale, BRS; generalized anxiety scale, GAD-7; mental health inventory, MHI; visual analog scale, VAS; short …

Characteristics Of Helicopter Accidents Involving Male And Female Pilots, Scott S. Burgess, Robert O. Walton, P. Michael Politano

International Journal of Aviation, Aeronautics, and Aerospace

Studies examining aviation accidents have not found differences in accident rates by gender, though there may be gender differences in the types of accident. Baker, Lamb, Grabowski, and Rebok (2001) examined fixed-wing aviation accident rates of male and female private pilots and found that males were more likely to have accidents related to inattention or poor planning while female pilots were more likely to have accidents due to mishandling the aircraft. This research analyzed the National Transportation Safety Board’s aviation accident database system to examine the severity of injury and aircraft damage in rotary-wing (helicopter) accidents by gender. The data …

Changes In Reach To Eat Movement Control After Intensive Training For Children With Unilateral Cerebral Palsy, Yaching Hung, Aryeh D. Spingarn

Publications and Research

Ya Ching Hung EdD. and Aryeh Spingarn EP-C, CSCS, EIM-Level 2 Queens College, City University of New York Department of Family, Nutrition, and Exercise Sciences, Changes in Reach to Eat Movement Control After Intensive Training for Children with Unilateral Cerebral Palsy. Purpose: The current study compares the effects of an intervention on children with Congenital Hemiplegia during a simple eating task using kinematic analyses. Previous studies looked at simple bimanual tasks such as opening a drawer; no studies examined the effects of intensive training on unimanual reach, grasp, and eat movement control. Methods: 20 children with Unilateral Spastic Cerebral Palsy …
