Item Influence of alpha intrusion during sleep: psychological and physiological implications(Montana State University - Bozeman, College of Letters & Science, 2022) Greenlund, Ian Mark; Chairperson, Graduate Committee: Jason CarterPoor sleep quality is pervasive in developed societies from chronic sleep disturbances or self-imposed sleep curtailment. Sleep disorders like insomnia are associated with regular sleep difficulties including sleep initiation and maintenance. Anxiety and depression exhibit a bidirectional relationship with insomnia, potentially exacerbating poor sleep quality and altering sleep microarchitecture via high frequency electroencephalographic (EEG) intrusion. This includes wake EEG alpha and beta rhythms. An association between high frequency intrusion and psychological dysfunction is present, but little is known regarding alpha and beta frequency intrusion 1) presence with state and trait anxiety symptoms, 2) impact on nocturnal blood pressure regulation, and 3) exacerbation with binge alcohol consumption. In study 1, we examined the relationship between state and trait anxiety severity with alpha and beta intrusion during stage N2 sleep, slow wave sleep (SWS), and rapid eye movement (REM) sleep in 32 participants. We demonstrated that alpha and beta frequency intrusion was augmented in participants with higher state, but not trait anxiety. In study 2, we investigated whether alpha and beta frequency intrusion impacted nocturnal blood pressure regulation in 36 young, healthy adults. Overall, systolic arterial pressure (SAP) dipping and cardiovagal baroreflex sensitivity (cvBRS) were not related alpha and beta spectral power during sleep. In study 3, we explored whether binge alcohol consumption could further exacerbate alpha and beta intrusion during sleep in higher state and trait anxiety participants in 31 participants. A secondary aim of this study was to determine if high frequency spectral power was different between sexes following alcohol consumption. Following laboratory familiarization night (study 2), participants were tested twice, ~1 month apart in a randomized, crossover design consuming either an alcohol dose (study 3) based upon biological sex and body weight, or fluid control beverage (study 1) two hours prior to lights out. Alpha and beta spectral power was not different between lower and higher state and trait anxiety, but was augmented in females compared to age-matched males. Collectively, these studies are the first investigate alpha intrusion presence with state and trait anxiety symptoms, impact on nocturnal blood pressure regulation, and sex specific exacerbation following alcohol consumption.Item The effect of local alcohol access on lottery purchases(Montana State University - Bozeman, College of Agriculture, 2022) Peterson, Ridge Walter; Chairperson, Graduate Committee: Isaac SwensenThe relationship between gambling and drinking has attracted significant attention from researchers but has been primarily explored in the limited context of laboratory experiments and cross-sectional surveys. In this thesis, I exploit variation in county and city-level 'wet' laws in the state of Texas to estimate the causal effect of local alcohol access on gambling, using per-capita expenditures on two major lottery games, Powerball and Mega Millions, as a measure of gambling consumption. I find that the passage of a city or county-level wet law is associated with a large and significant increase in lottery consumption. While this increase in lottery purchases is observed following the legalization of any alcoholic beverages at the county level, at the city level the effect appears to be driven by laws legalizing the sale of beverages for on-premise consumption. While I cannot distinguish the mechanism by which alcohol availability may affect lottery sales, the implication of this finding is consistent with existing research which finds complementarity between alcohol and gambling.Item The drinking habits of students and their knowledge of alcohol in selected Montana high schools(Montana State University - Bozeman, 1970) Schwarz, Robert JosephItem The extent of adolescent problem drinking in Gallatin County and existing treatment programs for their rehabilitation(Montana State University - Bozeman, 1976) Peterson, John EdwardItem Falling over in Philadelphia : early American psychotropy and transatlantic intoxication(Montana State University - Bozeman, College of Letters & Science, 2014) Taylor, Michael John-Sibbald; Chairperson, Graduate Committee: Billy SmithThis thesis explores the relationship among early Americans, taverns, and alcohol. It analyzes the extent to which alcohol and the drunkenness that frequently accompanied and shaped early American history. It argues that the Transatlantic marketplace functioned as a drug that early Americans associated with consumerism, including rum, wine, beer, and other beverages. It also examines the role of centralized colonial authority, questioning the effectiveness of tavern legislation in regards to public intoxication. Furthermore, it scrutinizes taverns as not only social and political institutions but also as biological institutions, a social necessity that exploits our evolutionary past. The research is interdisciplinary, using an eclectic mix of social and biological sciences, including neurology and social psychology, chemical toxicology and anthropology. Alcohol is a powerful chemical and it shares a long and storied relationship with our species. Taverns are vital, but neuro-consciousness and intoxication are the stars of this thesis. Alcohol is the great Silent American Actor and it will be treated as such throughout this work.Item Behind the Big Sky bar : the Montana alcohol servers' study(Montana State University - Bozeman, College of Education, Health & Human Development, 1995) Linkenbach, Jeffrey WarrenItem The effects of ethanol exposure on the morphological development of the Oculomotor nucleus in the rat(Montana State University - Bozeman, College of Letters & Science, 1992) Burrows, Robert ClaytonItem A survey of drinking behavior among Montana State University students and the potential for problems with alcohol : implications for counseling services, alcohol education, and student personnel services(Montana State University - Bozeman, College of Education, Health & Human Development, 1976) Fleming, Robert JohnItem Dehydration of an ethanol-water mixture by sorption using barley as the sorbent(Montana State University - Bozeman, College of Engineering, 1983) Law, JamesItem Early ethanol exposure in artificially-reared rats(Montana State University - Bozeman, College of Letters & Science, 1986) Fisher, Beatrice S.
