Screening For The Suitable Signal Peptide For Secreted Nattokinase Expression In E. Coli Using An In Silico Approach: Precursor Vs. Mature Forms, Dewi Purwani Caya Ningsih, Kartika Sari Dewi, I Wayan Martadi Santika, Ade Andriani, Joko Pebrianto Trinugroho, Muhammad Yusuf

Makara Journal of Science

Nattokinase (NK), an enzyme with thrombolytic activity, has been widely used in treating cardiovascular disease. The expression of NK in the E. coli cell host is favored due to its several benefits, though it often results in inclusion bodies. Appropriate signal peptides can be attached to the N-terminus of a protein to initiate a secretory expression system, thus preventing the nascent protein from aggregating in the cytoplasm. This study aimed to identify suitable signal peptides for the secretory expression of active NK in E. coli and to investigate the impact of pre-protein in NK secretion using an in silico approach. …

Bullying Prevalence And Persistence In Rural And Urban Settings, Eric Landers, Juliann Sergi Mcbrayer, Monika Krah, Meredith A. Rausch

The Rural Educator

Bullying is a serious issue in schools, affecting students’ physical health, academic performance, and mental well-being. It involves repeated, intentional aggression—physical, verbal, social, or online—that creates a power imbalance between the bully and the victim. Over time, it can lead to depression, low self-esteem, substance abuse, and even criminal behavior. Bullying varies by environment. Urban schools may see more peer aggression due to social instability, while rural schools face challenges like social isolation and unique power dynamics. Rural students face higher and more persistent bullying and repeated incidents at a higher rate than their urban peers. A growing concern is …

This disparity limits their ability to acquire the same resources …

Who Gets Closed? Twenty Years Of Access-Restricting School Closures In Arkansas, Mara C. Tieken, Christine Murray

The Rural Educator

Many states are facing dropping enrollments, budget shortfalls, and pandemic-era learning loss, and, looking to maximize efficiency and strengthen academics, they are considering district consolidation and school closure. Yet school closure is a highly contested issue, and research suggests that closure can harm students and communities. This study used discrete time survival analysis to investigate the demographic and institutional factors associated with access-restricting closures of rural schools in Arkansas from the 2003–2004 school year to the 2022–2023 school year. We looked at these closures—nearly all of them preceded by district consolidation due to under-enrollment or academic or fiscal sanction—to explore …

Updates To The Definition Of Rural, Daniel Showalter

The Rural Educator

First appearing in “Why Rural Matters 2025: People, Place, and Possibility,” this essay explains how changes to U.S. Census Bureau definitions of “urban” after the 2020 census have significantly reshaped which school districts and schools are classified as rural. These updates—such as raising population thresholds and redefining density—have led to many districts shifting classifications, with far more becoming newly rural than leaving that category. As a result, rural student counts have increased substantially, although this increase mostly reflects reclassification rather than demographic change. These shifts have important implications for funding, research, and policy decisions related to rural education.

Building Trustworthy Information Systems: A Unified Framework For Comparative Risk Detection, Parisa Momeni

USF Tampa Graduate Theses and Dissertations

Risk detection in large scale information systems increasingly depends on heterogeneous data generatedby both centralized and distributed ecosystems. While centralized systems provide curated and validated reports, distributed environments produce large-scale and real-time observational evidence. Existing computational approaches analyze these ecosystems in isolation, limiting systematic comparison of risk repre-sentations across heterogeneous sources.

This dissertation presents a unified computational framework for comparative risk detection across centralized and distributed information systems. The framework provides a domain independent methodology for transforming heterogeneous risk reporting data into comparable multidimensional representations. To enable interpretable comparison of heterogeneous risk distributions, this work introduces the Geometric Overlap Score …

Seeing Around Corners: An Indirect Light Transport Decomposition Framework For Fusing Physics And Learned Priors, Fadlullah Raji

USF Tampa Graduate Theses and Dissertations

Non-line-of-sight (NLOS) imaging, or seeing around corners, is the ability to recover information about objects hidden from direct view and remains one of the most compelling challenges in computational imaging. Existing approaches fall broadly into two categories: active and passive. Active time-resolved methods achieve impressive performance but require specialized pulsed laser hardware and ultrafast detectors, making them expensive and limited by slow measurement acquisition. Passive NLOS methods, which instead exploit the subtle soft shadows (penumbrae) cast by a hidden scene onto a visible matte surface, have recently emerged as a practical alternative. However, existing passive approaches are largely limited to …

Aligning Perspectives: Exploring Parent-Youth Agreement On Well-Being And The Impact Of Positive Psychology On Communication & Relationship Habits, Daijah N. Hines

House Sparrow Invasion Success Across Ecological, Immunological, And Molecular Scales, Kailey Marie Mccain

USF Tampa Graduate Theses and Dissertations

Biological invasions offer natural experiments for studying how organisms cope with ecological novelty. Although invasion success is often attributed to enemy release, introduced organisms do not enter enemy-free environments. Instead, they enter heterogeneous landscapes in which some familiar enemies are absent, others remain, and entirely novel enemies may be encountered. The question, then, is how invaders (hereafter non-natives) are poised to respond to these threats? This dissertation examines whether successful invasions in house sparrows (Passer domesticus) is associated with shifts in pathogen exposure, immune dynamics in blood, gut physiology, and gene co-expression network structure.
