Decolonizing The Western Perception Of Afghan Women: A Feminist Critique, Parwana Azimi

Honors Program: Senior Projects (Public)

Abstract: Feminist theory and activism have often been reduced to singular movements from Western literature and history. Thus, the exploration of Feminist theory is often limited to Western ideology and values. In doing so, Western Feminism has primarily promoted the rights of Women living in developed countries while leaving women in developing countries or otherwise out of the discussion of women’s rights and status. Most often, women's rights struggles outside of the West are seen as colonial projects which portray Muslim women as helpless and requiring liberation from their cultures. A prominent example of this is the case of Afghan …

Exploring Subtype C Hiv-1 Tissue Reservoirs And The Impact Of Cannabis Use In Virally Suppressed African Individuals, Zhou Liu

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Antiretroviral therapy (ART) has dramatically prolonged the lives of people living with HIV (PLWH), but it is not curative as it cannot eliminate integrated HIV-1 proviruses in different tissue reservoirs. Even though subtype C HIV-1 accounts for almost half of global HIV-1 infections, few studies had evaluated HIV-1 reservoirs for this subtype. Many co-factors, including the lifestyle factor cannabis use, have been investigated for their potential effects in HIV-1 infection. However, only limited information exists regarding cannabis’s effects on HIV-1 infections in vivo, and the impact of cannabis use on HIV-1 parenchymal tissue reservoirs is unexplored. This dissertation aims to …

The Impact Of A Pgym Variant On Myophosphorylase Deficiency In Red Angus Composite Cattle And Changes In The Skeletal Muscle Transcriptome Due To The Intramuscular Administration Of Lidocaine In Wether Lambs, Mackenzie Christin Batt

School of Biological Sciences: Dissertations, Theses, and Student Research

Project 1 focused on eight calves in a Nebraska herd (composite Simmental, Red Angus, Gelbvieh) that displayed exercise intolerance during forced activity. Available sire pedigrees contained a paternal ancestor within 2-4 generations in all affected calves. Pedigrees of the calves’ dams were unavailable, however, the cows were ranch-raised and retained from prior breeding seasons, where bulls used for breeding occasionally had a common ancestor. Therefore, it was hypothesized that a de novo autosomal recessive variant was causative of exercise intolerance in these calves. A genome-wide association analysis followed by whole-genome sequencing led to the identification of a variant in the …

Department of Animal Science: Dissertations, Theses, and Student Research

Three experiments were conducted at the Gudmundsen Sandhills laboratory near Whitman, Nebraska. Experiment 1, a retrospective regression analysis, evaluated the impact of heifer percentage of mature body weight (BW) at breeding on heifer performance, subsequent pregnancy rates, and calf production. Overall pregnancy rates were greater (P < 0.01) for heifers at 60 to 70% of mature BW than 50 to 55%, with no differences in pregnancy rates (P ≥ 0.15) after 2-years of age. Heifers at 50 to 60% of mature BW had a greater (P = 0.05) proportion give birth in the first 21-d. A higher percentage of mature BW at breeding resulted in greater (P < 0.01) BW at birth and weaning for offspring.

Experiments 2 and 3 were 3-year studies that evaluated the impact …
