The Partisan Politics That Led To The Spanish-American War, Donald E. Thompson Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis explores how partisan politics played a major role in leading the United States into the Spanish-American War. With the unprecedented economic depression that began in 1893, many American politicians exploited a rebellion in Cuba to distract Americans from their own financial problems. During the administration of Grover Cleveland politicians from all political parties supported American intervention in Cuba on behalf of the rebels. This show of support for the Cuban rebels by politicians was designed to rally the American public around a common cause and highlight the difference between them and the unpopular President Cleveland who opposed American …

Development And Evaluation Of A Minimally Invasive Sampling Technique To Estimate The Age Of Living Birds, Crissa K. Cooey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Using pest species in initial studies of pentosidine (Ps) aging research for birds may be the catalyst to discovering more effective population control strategies for pest, invasive, and hard to manage birds. Pentosidine is an irreversible, stable, fluorescent, collagen cross-link, created through the Maillard reaction, which has been found to accumulate throughout the lifetime of an organism in various body parts such as skin, lens crystalline, and dura matter. Pentosidine assays are more accurate at determining the age of adult birds in comparison to plumage coloration, eye and mouth color, feather wear, and molt sequences due to the discovery that …

Strategies Of Prevention: Extending The Concept Of Preventive War And Understanding Its Implications, Steven T. Walker

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation contributes to the literature on prevention in two specific ways. First, it broadens the concept of preventive war, developing the idea that dominant states have a choice when it comes to dealing with rising challengers. The choice is not a dichotomous variable of either war or no war. Instead, there is a range of choices that decision makers within the dominant state have at their disposal. This dissertation examines the relationship---over time---between two conflictual states, one in relative decline and the other in relative ascendance, and studies the response of the dominant but declining power. Second, I focus …

Emotional, Cognitive, And Family Systems Mediators Of Children's Adjustment To Interparental Conflict, Gregory M. Fosco, John H. Grych

Psychology Faculty Research and Publications

Emotional, cognitive, and family systems processes have been identified as mediators of the association between interparental conflict and children's adjustment. However, little is known about how they function in relation to one another because they have not all been assessed in the same study. This investigation examined the relations among children's exposure to parental conflict, their appraisals of threat and blame, their emotional reaction, and triangulation into parental disagreements. One hundred fifty ethnically diverse 8- to 12-year-old children and both of their parents participated in the study. Comparisons of 3 models proposing different relations among these processes indicated that they …

Photopolymerization And Characterization Of Thiol-Enes And Thiourethanes, Qin Li

Dissertations

Compared to conventional acrylic monomer systems, thiol-ene photopolymerization, an efficient click process leading to the formation of dense and uniform molecular networks, has several distinct advantages including relative insensitivity to oxygen inhibition, high monomer conversion and low shrinkage. Although there has been a revival of interest in thiol-enes in the past 6 years, the structure-property relationship of these networks has not been explored in detail. For future applications, thiol-enes with higher shelf-life stability and glass transition temperatures need to be used. Sulfur containing urethanes, thiourethanes and dithiourethanes are a class of widely used materials due to their distinct properties such …

Coincidence Theory: Seeking A Perceptual Preference For Just Intonation, Equal Temperament, And Pythagorean Intonation In Excerpts For Wind Instruments, Derle Ray Long

Dissertations

Coincidence theory states that when the components of harmony are in enhanced alignment the sound will be more consonant to the human auditory system. An objective method of examining the components of harmony is by investigating alignment of the mathematics of a particular sound or harmony. The study examined preference responses to excerpts tuned in just intonation, Pythagorean intonation, and equal temperament. Musical excerpts were presented in pairs and study subjects simply picked one version from the pair that they perceived as the most consonant. Results of the study revealed an overall preference for equal temperament in contradiction to coincidence …
