Using Anisotropy Of Magnetic Susceptibility (Ams) To Identify A Tectonic Lineation In The Pulo Do Lobo Formation In The Southern Iberian Shear Zone Near Aracena, Spain, Devin Levang

Theses and Dissertations

The Southern Iberian Shear Zone (SISZ) is a Variscan-aged suture representing the closure of a small ocean basin during the Carboniferous. The SISZ is bounded on either side by the well-studied, relatively homogeneous Beja-Acebuches Metabasites (BAM) and the complex and heterogeneous accretionary metasedimentary rocks of the Pulo do Lobo (PdL). The SISZ underwent a combination of shortening and lateral shearing known as transpression. Despite a very well-developed tectonic foliation, kinematic interpretation in the PdL is made difficult by a lack of easily identifiable lineations. Anisotropy of magnetic susceptibility (AMS), a geophysical technique measuring the relative anisotropy of magnetic susceptibility axes …

Virtual Excavations: Digital Repositories, Data Reuse, And Ethically Accessible Archaeology, Allison Lindsey Densmore

Theses and Dissertations

Archaeological investigations produce massive amounts of data, yet these data are often sequestered by the original researchers or put behind paywalls that restrict access to academic publications. This inaccessibility makes it difficult to justify the destructive nature of archaeology. Open-access digital data management systems such as the Digital Archaeological Record (tDAR) provide archaeologists with new ways to preserve, share, and, most importantly, reuse archaeological data to combat this issue of data sustainability. The goal of this project is to investigate how these digital repositories allow for ethically responsible data access and reuse, thus mitigating the cycle of destruction, hoarding, and …

Stress And Parity Among Female Vervet Monkeys (Chlorocebus Pygerythrus) At Two Sites In South Africa, Jo Gansemer

Theses and Dissertations

This thesis examines the hypothesis that in both Soetdoring and !Gariep populations, a femaleSouth African vervet's parity status (nulliparous or parous) affects her physiological stress levels. Vervet monkey ecology and life history are examined to contextualize the relationship between stress and parity. The testing of this hypothesis involves the analysis of hair cortisol concentrations (HCC) of samples from nulliparous and multiparous adult females of the two different South African sites. The HCC was statistically analyzed to look for correlations between stress, parity status, and site. No significant relationship between stress and parity status was found. However, significant relationships were found …

However, critical knowledge gaps exist in wastewater surveillance, stemming from a lack of understanding in sewer microbial ecology. Ecology reveals trends in how communities respond and adapt to change, which has far-reaching implications for identifying effective strategies for disease …

Prior Experiences Of Racial Discrimination Impact Acute Resting-State Connectivity Of The Bnst As A Predictor Of Ptsd In Black Adults, Kevin Petranu

Theses and Dissertations

Altered resting-state activity of the bed nucleus of the stria terminalis (BNST) – which mediates anxious arousal and threat monitoring – is implicated in the etiology of posttraumatic stress disorder (PTSD). Experiences of racial discrimination can also increase one’s risk for developing PTSD by eliciting chronic states of hypervigilance, which impair essential resting-state processes related to fear extinction. Considering the frequency in which Black Americans experience racial discrimination, the current study investigated acute BNST resting-state functional connectivity as a predictor of future PTSD symptoms, as well as the impact of racial discrimination on the BNST as a predictor of PTSD. …

Differentiating Human From Nonhuman Bone: Insights From A Medical Examiner’S Collection, Kenosha, Wisconsin, Jordan L. Fourshee

Theses and Dissertations

Forensic anthropologists who work in medical examiner’s offices or similar contexts frequently need to differentiate nonhuman from human skeletal or partially decomposed remains. If we, forensic anthropologists, were more aware of which nonhuman bones were most common in such situations, we might be able to improve our training programs. The Office of the Chief Medical Examiner in Kenosha County, southwest Wisconsin, accumulated over 1,940 nonhuman bones over a period of several years, most likely primarily between 2000 and 2005. These are the focus of this thesis, which presents a quantitative analysis of the most frequently encountered taxa and elements. The …

ABSTRACT

OCON AT WAR:THE OCONOMOWOC HOME FRONT DURING THE SECOND WORLD WAR

This thesis will examine the local home front propaganda in and around Oconomowoc, Wisconsin (Waukesha County) during the Second World War and compare the Oconomowoc area propaganda to Wisconsin overall and to the national experience. Enlistments, war bond sales, USO events, parades, radio programs/speeches, films, music, popular books/comic books, and images, are the main types of “cultural locations” that I am using as propaganda. I have found solid examples of posters and advertisement images from local newspapers that provide a wealth of information about the way fear, love, …

Jacques Maritain And Popes Pius Xi And Xii On The Church-State Relationship, Patrice O'Rourke Linn

Theses and Dissertations

Jacques Maritain (1882-1973) was a French Catholic philosopher, acknowledged as one of the most influential non-clerical Catholics of the twentieth century. During this time, the Catholic Church was experiencing the slow process of political displacement. Maritain and the contemporary popes addressed how the Church should function within the modern context. Both began the century sympathetic to right-leaning governments and political parties that supported the Catholic Church but shifted over time to embrace a less direct approach. This thesis will demonstrate the change over time of Maritain’s position and how it paralleled the positions of Popes Pius XI and Pius XII. …

Deciphering The Firing Patterns Of Hippocampal Neurons During Sharp-Wave Ripples, Kourosh Maboudi Ashmankamachali

Theses and Dissertations

The hippocampus is essential for learning and memory. Neurons in the rat hippocampus selectively fire when the animal is at specific locations - place fields - within an environment. Place fields corresponding to such place cells tile the entire environment, forming a stable spatial map supporting navigation and planning. Remarkably, the same place cells reactivate together outside of their place fields and in coincidence with sharp-wave ripples (SWRs) - dominant electrical field oscillations (150-250 Hz) in the hippocampus. These offline SWR events frequently occur during quiet wake periods in the middle of exploration and the follow-up slow-wave sleep and are …

The Nemo region of South Dakota’s Black Hills offers an ideal location to study transpressional shear zones because it hosts an exposed Archean lithological boundary between two contrasting rheological units, the Boxelder Creek Quartzite (BCQ), a rift-depositional quartzite, and the Blue Draw Metagabbro (BDM), a metagabbro sill, deformed within a ductile shear zone that represents the beginning of main-phase formation of the North American continent as we know it today. The tectonic setting of the Black Hills is at the eastern edge of the Archean Wyoming province, located near the Trans-Hudson Orogeny suture zone that formed between the Wyoming and …

Printed And Bound: The Publishers' Case Binding And 19th-Century Women's Critique Of Marriage, Carolyn Suneja

Theses and Dissertations

This dissertation investigates the coevolution of industrial book formats in the 19th century and women’s critique of marriage in fiction, arguing that the highly decorated case binding both reflected and shaped broader cultural anxieties engendered by the accessibility of new literary forms to mass audiences and the impact of that literature on the cultural logics by which women understood their roles and options. Given the reciprocal relationship between the mechanisms of industrial print and women’s writing, the material conditions of book production are important considerations for the literary scholar. The four novels examined in this dissertation—Fanny Fern’s Rose Clark, Harriet …
