Dietary Probiotic Supplement Attenuates Methamphetamine-Induced Conditioned Place Preference In Female Sprague-Dawley Rats, Kristen Powell

Masters Theses

Substance use disorders (SUD) represent a global public health crisis with limited effective treatment options. Recent findings implicate the gut microbiome and gut/brain axis in the pathophysiology of SUDs. Several preclinical studies have established that psychostimulants alter gut microbiome composition, but no published studies have assessed behavioral effects of dietary probiotic supplements on drug-induced behavioral changes. This study utilized rodent conditioned place preference (CPP) as a behavioral index of conditioned drug reward to determine if a dietary probiotic supplement alters the behavioral effects of (+)-methamphetamine (METH). Fifty-four adult female Sprague-Dawley rats were randomly assigned to receive either a standard rodent …

41 For Freedom: Ballistic Missile Submariners And The Nuclear Deterrent Shield During The Cold War, Jeremy Daniel Long

Masters Theses

Ballistic missile “boomer” submarines were developed in the 1960s as a response to the Soviet launch of the Sputnik satellite which proved the Soviet Union could launch a missile targeting anywhere on Earth. They made use of new nuclear power technology which allowed submarines to stay underwater indefinitely, limited only by the food they could carry to feed their crews. Ballistic missile submarines have served continuously since 1960, patrolling the ocean as the second-strike capability that makes nuclear deterrence possible. The men who served aboard the “41 for Freedom” ballistic missile submarines made innumerable sacrifices and contributed greatly to national …

The Relationship Between Resilience, Coping, And Social Media, Lillian N. Hurley

Masters Theses

This study was designed to explore relationships between measures of resilience, coping strategies, social media usage, and depression. Resilience refers to one's ability to endure and recover from adversity. Many theories about what contributes to the development resilience have been explored without a clear consensus. Taormina (2015) argued that adult personal resilience is comprised of four dimensions - determination, endurance, adapatability, and recuperability. Coping, a construct related to resilience, is the process of regulating emotions, cognition, behavior, physiological responses, and the environment in response to stressful events. Past research indicated those with poorer mental health have the tendency to use …

Effects Of Low Dose Mixtures Of 3,4-Methylenedioxypyrovalerone And Cocaine On Locomotor Activity And Brain Monoamine Content In Sprague-Dawley Rats, Robert J. Kohler

Masters Theses

Synthetic cathinones, known as “bath salts” on the illicit drug market, pose a significant and growing public health concern. 3,4-Methylenedioxypyrovalerone (MDPV), one of several popular constituents of the illicit bath salts, produces similar pharmacological actions to cocaine, albeit with greater potency. The present study sought to characterize behavioral and neurochemical effects of repeated exposure to MDPV alone and in combination with cocaine. Male Sprague-Dawley rats were randomly assigned to one of four treatments: 1 mg/kg MDPV, 5 mg/kg cocaine, 1 mg/kg MDPV + 5 mg/kg cocaine, or saline. Locomotor activity was assessed for one hour immediately before and one hour …

Sleep Hygiene Practices: A Cross Cultural Survey Of Sleeping And Dreaming In College Students, Ivan Noe Martinez Salazar

Masters Theses

There is consensus that a sizeable percentage of people in most developed countries do not obtain adequate amounts or quality of sleep. These disruptions in sleep, when chronic and severe, can lead to psychological, behavioral and health consequences. The focus on behavioral and contextual factors that impact sleep has been termed “sleep hygiene”. An on-line anonymous survey collected sociodemographic information, as well as self-reports on sleep, sleep hygiene practices and dreaming across two cultural groups (English & Spanish speaking responders). A total of 204 participants (majority of them college and graduate students) answered the survey. Both cultural groups, English and …

The Validity Of The Obsessive-Compulsive Syndromes As Emotional Disorders, Doty Jennings

Masters Theses

Recent changes to the Diagnostic and Statistical Manual of Mental Disorders have grouped together syndromes which are referred to as the obsessive-compulsive spectrum (OCS). The grouping of these syndromes is disputed because of lack of empirical verification for an organization purportedly based on research that supports similarity of observed symptoms. The taxonomy of emotional disorders was tested as an alternative model. Consistent with the model of the emotional disorders, this empirical research tested two proposed characteristics. The first was whether three OCS syndromes (hoarding syndrome, body dysmorphic syndrome, and obsessive compulsive syndromes) shared the broad factor of neuroticism or negative …

We're Not Thugs And Rappers: An Examination Of African American Male Athletes' Perceptions Of The Media, Keia Janese Bragg

Masters Theses

Manipulation of stories and events expose issues of false representation and stereotyping within the mainstream media. This research examined the media’s role in shaping the behaviors and experiences of African American male athletes while using Critical Race Theory as the framework in conducting research. A focus group consisting of six former African American male student athletes was conducted. A semi-structured interview schedule was used in order to allow for open discussion. The Constant Comparison Method was instrumental in thematizing the data while QDA Miner software was used to analyze the data. The findings suggested that African American male athletes feel …

A Neuropsychological Perspective On The Efficacy Of Typical And Atypical Medication Treatment For Chronic Schizophrenia Regarding Executive Functioning, Eric Hart

Masters Theses

This study investigated the efficacy of current medication treatment procedures for chronic schizophrenics on neuropsychological measures. A total of twenty participants from the Coles County Mental Health Center, who met DSM-IV criteria for chronic schizophrenia, volunteered to be administered the Wisconsin Card Sorting Test (WCST)-64 card version as a means of assessing neuropsychological executive functioning. A total of twenty participants free of any diagnosable psychological disorder also volunteered to be administered the WSCT-64, which served as a control group. The staff psychiatrist at the Coles County Mental Health Center completed the Positive and Negative Syndrome Scale (PANSS) in order to …

The Acute Effects Of Cocaine In Pigeons Performing Under A Progressive-Ratio Schedule, Claudia Ann Jones

Masters Theses

Although the progressive-ratio (PR) schedule has been used frequently to quantify the reinforcing effectiveness of self-administered drugs, it has seldom been used to examine the effects of drugs on food-maintained behavior and has never been used to evaluate the effects of cocaine on such behavior. In the present study, the effects of acute administrations of cocaine were evaluated in pigeons responding under a PR schedule of food delivery. Overall, cocaine produced a dose-dependent effect on food-maintained behavior. In general, acute administrations of cocaine at 0.56 to 3.2 mg/kg increased breaking points, whereas doses above 5.6 mg/kg decreased breaking points. Low …

Mmpi Profiles Of Sexual Perpetrators, Steven G. Vaupel

Masters Theses

The purpose of this study was to compare MMPI scores of 60 men referred for assessment and/or counseling at community mental health facilities. No MMPI protocols were excluded due to elevated validity configurations (70T or above). Forty of the referrals were referred for suspected child sexual abuse. Twenty of the referrals admitted (Admitter) to sexually abusing a child at the time of referral and twenty did not admit (Nonadmitter) to sexually abusing a child when referred. A control group of the remaining twenty subjects were referred for various offenses, none of which included sexual offenses against children. Significant differences were …

Schizophrenia: Institutionalization And Dependence, Jerry L. Boyd

Masters Theses

The review of the literature dealt with dependence in mental patients. Additional focus was given to the process of patienthood as it relates to the acquisition of dependence. Research on schizophrenia was then discussed and the special interaction of the schizophrenic and the environment was explicated. Finally, attention was given to the unique relationship between the schizophrenic mental patient and dependence.

57 Ss from a rural area in the midwestern United States were given the 16 Personality Factor Questionnaire (Form C). Ss were divided into 3 groups. The groups were matched according to age, sex, race, marital status, and education. …

An Exploration Of The Relationship Between Loneliness And Differential Diagnosis In A Rural Mental Health Center, Kathryn Dunscomb

Masters Theses

The review of the literature discussed loneliness in general and specified three seperate forms of loneliness; social, psychic, and existential. The relationships between loneliness, social interaction, and pathology were discussed. 139 clients were given the Belcher Extended Loneliness Scale - Revised prior to therapy. They were assigned one of six diagnostic categories to determine loneliness score (LS), diagnostic, and sex interactions. An analysis of variance found a significant difference (p <.0001) between the diagnostic categories’ LS. The schizophrenic’s and the neurotic’s LS s were significantly higher (<.05) than the remaining categories. The males had significantly (p <.036) higher LS than the females. It was also hypothesized that the degree of loneliness would increase the lower the diagnostic developmental level. The hypothesized order was not consistent with the results. Further research was recommended.
