Adjudicating Technology Facilitated Violence Against Women In Egypt: Between The Text And The Application, Eman E. Zidan

Theses and Dissertations

Technology-facilitated violence against women (TFVAW) has surged on digital platforms, leading to a sharp rise in victimization rates among girls and women globally. Egypt’s pioneering cybercrime legislation, though comprehensive, remains gender-neutral and inadequate in judicial application. Community perceptions reveal systemic gaps that erode public trust and fuel demands for specialized protections. This study analyzes Egyptian judicial responses to TFVAW cases through comparative jurisprudence with jurisdictions that feature gender-specific norms. Findings demonstrate that textual provisions alone fail to arrest this escalating phenomenon, underscoring the need for integrated reforms: tailored legislation, heightened awareness campaigns, and collaborative education on rights, duties, and societal …

Bearpaw Reserve Wildlife Monitoring And Mapping With The Wildlands Conservancy, Hope Hansen

Scripps Senior Theses

For my Environmental Analysis Capstone, I worked in a small group to monitor and map the wildlife at Bearpaw Reserve. Bearpaw Reserve, located in Forest Falls, California, is a 600 acre tract of wilderness that is owned by The Wildlands Conservancy. Bearpaw is located about an hour from Claremont, in the San Bernardino Mountains. The Wildlands Conservancy makes management decisions about its reserves while applying conservation research to the real world.

My group’s task was to use trail cameras to gather data on the wildlife at Bearpaw, then visualize this information into a GIS map. We used a combination of …

Push-Pull Farming System Helps Insure Smallholder Maize Production Under Climate Change, Yann Clough, Wilhelm May, Timothy Luttermoser, Dickens Nyagol, Nikolaos Alexandridis, Frank Chidawanyika, Mattias Jonsson, Charles A.O. Midega, Katja Poveda, Zeyaur R. Khan

All Peer-Reviewed Publications

Agroecological approaches harnessing in-field biodiversity have been highlighted as a sustainable way to reduce yield gaps, but long-term assessments of their ability to buffer production from weather extremes and increasing interannual and intraseasonal climate variability are scarce. Here, we analyze a 12-year dataset from 642 control vs. push-pull maize field pairs in western Kenya, where long-term climate trends include increasing temperatures and intensifying drought and rainfall. In push-pull, maize is intercropped with a fodder legume that improves soil fertility, suppresses weeds, and deters pests, and is bordered with fodder grasses attracting and suppressing the pests. We assess interactions between push-pull …

Sexual Di(Et)Morphism: Using Experimental Evolution To Test Whether Resource Partitioning Promotes Divergence Of The Sexes In Drosophila Melanogaster, Owen A. Jamieson

Theses and Dissertations (Comprehensive)

Sexual dimorphism has been a long-studied phenomenon in the field of evolutionary biology. Usually, these differences in morphology, physiology and/or behaviour between the sexes are studied through the parsimonious lens of sexual selection. However, there are natural history cases where this lens does not seem applicable. Some species show sex specific morphological traits whose presence may not be due to a direct benefit to reproduction, but a difference in how each sex interacts with the environment and differing selective pressures from the environment on either sex. Darwin even brought up examples of this kind of dimorphism and pondered their existence, …

The Role Of The Avian Medial Hippocampal Formation In High-Similarity Spatial Discrimination, Alexandre Lebel

Theses and Dissertations (Comprehensive)

Similar stimuli can create spatial-perceptual challenges, thus leading to errors in recall. To combat this interference, organisms rely on processes within the hippocampal formation (HF) that support the discrimination of highly similar memories. In mammals, memory interference is thought to be reduced by decreasing the correlation between traces of similar events; a process termed pattern separation, often by the dentate gyrus. The extent to which birds, which have granule cells (GCs) but lack a dentate gyrus, utilize HF-dependent mechanisms to mitigate memory retrieval errors remains unclear. This study investigates the role of the triangular region and area V (proposed homologs …

Endogenous Light In The Brain: Investigating Sources, Propagation, And State-Dependent Emission, Emre Cicek

Theses and Dissertations (Comprehensive)

Ultraweak photon emission (UPE), and by extension light, has long been thought to be a modality of communication in nature. Prior studies have already identified that UPE can depend on cell type and can be used to discern between malignant and benign cells. However, besides theoretical models, not much effort has been made to identify possible biological structures that would allow for light to be used as a method of communication in the human body. According to the framework set by Shannon’s Information Theory, for communication to be possible at minimum a transmitter, a transmission channel, and a receiver are …

Sediment Redox-Driven Iron Flux And Phytoplankton Community Responses: Implications For Cyanobacterial Suppression And Functional Stability Across Boreal Lakes, Julia K. Kozak

Theses and Dissertations (Comprehensive)

Freshwater eutrophication contributes towards the development of cyanobacterial harmful algal blooms (cHABs), but nutrient availability alone does not fully explain variation in phytoplankton community composition or physiological performance. While phosphorus (P) availability has been known to regulate phytoplanktonic biomass, iron (Fe) is an important micronutrient supporting Fe-heavy processes within cyanobacteria (i.e., nitrogen fixation and photosynthetic electron transport). Sediment Fe availability in freshwater ecosystems is regulated by reduction oxidation (redox) conditions at the sediment-water interface (SWI), where nitrate (NO₃^-) has been found to maintain oxidizing conditions and prevent the reduction of Fe(III) to more readily bioavailable soluble Fe(II), …

Nourishing Births: A Program Evaluation Proposal For Community-Based Nutrition Education, Food Access, And Garden Engagement Among Black Birthing People, Naa Deedei-Vera Hammond

Master's Projects and Capstones

Black birthing people in the United States continue to experience unequal maternal health outcomes, shaped in part by racism and barriers to nutritious food, culturally relevant health education, and supportive community spaces. While prenatal nutrition education and food assistance programs can provide important resources, information alone cannot address the challenges many people face when trying to access healthy and affordable food during pregnancy. The Nourishing Births Initiative is a proposed community-based maternal health program designed to respond to these needs by bringing together prenatal nutrition education, help connecting to food resources, community gardening, and peer support for Black birthing people …

Robust Statistical Methods For Microbiome Abundance Data, Yiming Shi

WUSM Theses and Dissertations – All Programs

Differential abundance analysis in microbiome studies aims to identify taxa whose abundance differs across biological or clinical conditions. The observed data are typically taxon-specific sequencing read counts, representing reads assigned to different taxa within each sample. These counts are indirect measurements of the underlying microbial abundance profile and are constrained by sample-specific library sizes. Microbiome count data are also typically sparse, overdispersed, and heteroscedastic. Together, these characteristics create substantial challenges for differential abundance analysis and make the results highly sensitive to normalization procedures, model specification, and the statistical methods used for inference.

Normalization defines the scale on which samples are …

Surveillance And Comparative Genomics Of Bacteria From Hospital And Human Reservoirs, Emily E. Benedict

WUSM Theses and Dissertations – All Programs

Bacteria are diverse and adaptable and, consequently, present in a wide variety of environments. They are capable of growing under intense pressures, including those brought on by the human immune system and disinfection strategies. To survive these pressures, bacteria develop resistances. Antimicrobial resistance, which occurs when a microbe is no longer responsive to the antibiotic intended to control it, is one such adaptation that presents an especially serious threat, as it limits treatment options for infections caused by antimicrobial resistant microbes. Similarly, the ability of bacteria to survive in environments subjected to heavy disinfection efforts, such as intensive care units …

Investigating The Ability Of Presequences To Influence Mitochondrial Protein Import, Youmian Yan

WUSM Theses and Dissertations – All Programs

Mitochondria are essential organelles housing over 1000 proteins, 99% of which are nuclear-encoded and synthesized in the cytosol. Most mitochondrial proteins are targeted by a positively charged sequence called the presequence, which lacks a common sequence motif and is poorly conserved across evolution. Accumulating evidence suggests that presequences encode meaningful information that influences mitochondrial protein uptake. For instance, multiple stress response models propose that stress sensing proteins contain “weak” presequences which allows them to monitor mitochondrial health. However, there is a lack of systematic examination about how presequences influence import kinetics and what constitutes presequence strength. These gaps in knowledge …

Port And Vessel Communication Traffic Intrusion Detection: A Variational Autoencoder‑Enhanced Multilayer Perceptron Approach, Chien-Lin Chiang, Hsien-Cheng Chou, Ming-Yuan Peng, Yi-Yuan Chiang, Yu-Shun Liu

Journal of Marine Science and Technology–Taiwan

Port and vessel networks increasingly operate on IP/Ethernet backbones with high‑noise, high‑dimensional traffic. We present a lightweight hybrid intrusion‑detection model that couples a variational autoencoder (VAE) with a multilayer perceptron (MLP) and augments training with a boundary‑oriented latent‑space mixup strategy. The VAE models the distribution of normal traffic and identifies anomalies through reconstruction errors. Subsequently, it generates robust latent vectors, enabling the MLP to perform highly accurate supervised classification. On the UNSW‑NB15 dataset, the proposed pipeline attains ≥97% accuracy and an outstanding recall of 99.56% in binary intrusion detection, and visualization of the latent space (PCA) together with reconstruction‑error analyses …

Sar Ship Detection Based On Shallow Feature Guidance, Chenxu Xia, Peng Chen, Ya Zhang, Ying Li

Journal of Marine Science and Technology–Taiwan

Maritime ship detection is of great significance for both military security and civilian applications. Synthetic Aperture Radar (SAR), with its all-weather and all-day imaging capability, plays a vital role in maritime surveillance. Nevertheless, SAR ship targets typically appear small in scale, embedded in complex backgrounds, blurred at boundaries, and easily confused with near-shore features, which pose substantial challenges for accurate detection. To address these issues, we propose a SAR ship detection network that integrates dual enhancements of small-object representation and edge information. The network introduces two key components: the Small Target Refine Pyramid (STRP) to strengthen shallow feature representation for …

Multiomic And Single-Cell Analysis Of Tumors And Their Immune Microenvironment For Personalized Cancer Therapy, Kartik Singhal

WUSM Theses and Dissertations – All Programs

Precision oncology aims to match cancer treatment to the biology of an individual patient’s tumor. However, tumors that share a diagnosis can differ in their molecular features, cellular composition, clinical course, and response to therapy, making it difficult to determine which treatment will benefit an individual patient. This dissertation integrates genomic, transcriptomic, and single-cell multiomic computational analysis to characterize tumors across their somatic alterations, transcriptional cell states, microenvironment, and the immune response they elicit.

The first study describes a rare case of donor-derived follicular lymphoma following kidney transplantation. Genomic profiling showed that the donor and recipient tumors shared 31 somatic …

Balancing Root-Zone Oxygenation And Rhizosphere Stability: The Impact Of Aeration And Hypoxia On Hydroponic Plant Growth, Christian D. Baker

All Graduate Theses and Dissertations, Fall 2023 to Present

As the global population and food demand continue to increase, growers must look to innovative and sustainable methods for plant cultivation. Hydroponics is a popular method of sustainable plant cultivation where plant roots are suspended over a liquid nutrient solution. Hydroponics uses less water compared to traditional agriculture because there is no evaporation or solution runoff. It also maximizes land use, requires fewer pesticides and herbicides, and enables year-round cultivation in controlled environments. However, indoor hydroponic systems rely on artificial lighting, which has higher energy costs than traditional farming methods. Optimizing growing conditions is therefore critical to ensure long-term economic …

Kinesiology Department Chairs’ Perceptions Of Their Training And Preparation, Kason O’Neil

Electronic Theses and Dissertations

Department chairs are responsible for leading academic departments in higher education.  These individuals regularly make important decisions regarding such things as managing faculty and academic programming, overseeing budgets, and supporting student needs. Despite these responsibilities, many people become department chairs without receiving formal leadership training. This study explored how kinesiology department chairs across the United States viewed their preparation for the role and the importance of leadership training. A total of 111 department chairs completed an online survey about their background, previous training, and the importance of training for different administrative responsibilities. The results showed that most chairs had little …
