By attending to the sociopolitical dynamics of drought and the development interventions that accompany it, I analyze how these forces restructure labor, land, food systems, and authority in ways that reproduce and exacerbate existing inequalities. Women’s coping strategies, ranging from begging and …

Commercial Attention Spaces: A Century Of Discourses, Measurements, And Models Of Attention In The Construction Of U.S. Advertising Markets, Jacob Saindon

Theses and Dissertations--Geography

A vast assemblage of networked devices populate our everyday spaces. Concomitant with the increasing ubiquity of media devices are advertisements. Indeed, many networked devices, specifically the “free-to-use” software applications, websites, or platforms displayed through them, are advertising-dependent. An assortment of firms within the commercial media industry—brands, agencies, publishers, vendors—work in concert to sustain a market for advertising. The core operation of the commercial media industry, I argue, is the production and exchange of attention as an economic object. In this study, I approach the production of attention and the framing of its markets as spatial processes. The continued growth of …

In‑Situ Characterization And Modeling Of Machining‑Induced Residual Stresses In Peripheral Milling Of Ti–6al–4v With Rounded Cutting Edges, Matthias Wimmer, Julius M. Schoop, Michael F. Zaeh

Mechanical Engineering Faculty Publications

The residual stress state in the sub-surface of machined components can significantly impact the properties and performance of parts, such as tribological properties, fatigue life, and dimensional distortion. The evolution of residual stresses depends on the selected process parameters and tool geometry, which affect the thermo-mechanical load imposed on the workpiece. The cutting-edge radius is among the most important factors influencing the resulting residual stresses. In this paper, a semi-analytical model for the determination of residual stresses after peripheral milling of Ti–6Al–4V is presented. It considers the physical principles of orthogonal machining, including the complex geometric and kinematic relationships during …

Coffey, Harindi R. Atapattu, Mustafa Ahmed, Qixuan Hu, Wenzhan Xu, Raunak Dani, Limei Wang, Chenhui Zhu, Kenneth R. Graham, Jianguo Mei, Letian Dou

Chemical and Materials Engineering Faculty Publications

Despite the outstanding electric properties and cost-effectiveness of poly- (3,4-ethylenedioxythiophene) (PEDOT) and its derivatives, their performance as hole transport layer (HTL) materials in conventional perovskite solar cells (PSCs) has lagged behind that of widely used spirobifluorene-based molecules or poly(triaryl amine). This gap is mainly from their poor solubility and energy alignment mismatch. In this work, the design and synthesis of a pyrrole-modified HTL (PPr) based on 3,4-propylenedioxythiophene (ProDOT) are presented for efficient and stable PSCs. As a result of the superior defects passivation ability, excellent contact with perovskite, enhanced hole extraction, and high hydrophobicity, the unencapsulated PPr-based PSCs showed the …

Neurology Faculty Publications

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer’s Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …

How Do Couples Of Autistic Children Perceive Their Quality Of Life? A Case Study Featuring Sequential Mixed Methodology, Amanda Duncan Dr.

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Families who have autistic children report significantly lower quality of life indicators than neurotypical families and those with other developmental disabilities (Bitsika & Sharpley, 2004; Brown et al., 2006; Charnsil & Bathia, 2010; De Sousa, 2010; Merkaj et al., 2013). However, the reports fluctuate between family members as mothers report more mental health challenges than fathers, including stress, anxiety, and depression (Dabrowska & Pstiula, 2010; Hodapp et al., 2003; Merkaj et al., 2013). Yet, these findings are based on the limited research that has been done on fathers and couples (Cheuk & Lashewicz, 2015; Osborne & Reed, 2008; Papageorgiou & …
