UNI Proud Documents

This project aims to provide the future of queer activists of this campus a better picture of the roots of activism on this campus. I think of this project as my own personal version of The Celluloid Closet, but instead of old movies it's old Northern Iowan articles. There has always been resistance at UNI, and this document hopes to show that resistance. It is however by no means complete, as often resistance has to occur in the shadows. What this work is hours and hours of searching the archives of The Northern Iowan, for those brief snapshots …

The Spiritual Well-Being Scale (Swbs) As An Indicator Of General Well-Being, Rodger K. Bufford, Jessica Cantely, Jaycee Hallford, Yadira Vega, Jessica Wilbur

Faculty Publications - Doctor of Psychology (PsyD) Program

Developed in the context of the subjective well-being movement in the 1970s, the Spiritual Well -Being Scale (SWBS) has stood the test of time. It was conceived within a theistic tradition and embodied the sense of well-being suggested in Biblical texts. The Old Testament greeting and blessing, shalom, seems to convey well the underlying concept of well-being. In this chapter we explore the empirical support and practical significance of the SWBS as a measure of well-being using the notion of biopsychosocial health as proposed by Engel and adapted by Sulmasy to include a religious/spiritual (R/S) dimension as well. Since the …

Mild Cognitive Impairment Classification Using A Novel Finer-Scale Brain Connectome, Yanjun Lyu, Lu Zhang, Xiaowei Yu, Chao Cao, Tianming Liu, Dajiang Zhu

Computer Science Faculty Research & Creative Works

Mild cognitive impairment (MCI) is recognized as a precursor to Alzheimer's disease (AD), a progressive and irreversible neurodegenerative disorder of the brain. The neurodegeneration of brain connectivity networks plays a pivotal role in the development and progression of MCI. Traditionally, brain networks are generated using coarse-grained brain regions, where the regions serve as nodes and their functional or structural connections are used as edges. Recently, a novel finer scale brain folding patterns named 3hinge gyrus (3HG) was identified, which is defined as the conjunctions coming from three directions on gyral crests. 3HGs have been shown playing an important role in …

Cav-Ad: A Robust Framework For Detection Of Anomalous Data And Malicious Sensors In Cav Networks, Md Sazedur Rahman, Mohamed Elmahallawy, Sanjay Madria, Samuel Frimpong

Computer Science Faculty Research & Creative Works

The adoption of connected and automated vehicles (CAVs) has sparked considerable interest across diverse industries, including public transportation, underground mining, and agriculture sectors. However, CAVs' reliance on sensor readings makes them vulnerable to significant threats. Manipulating these readings can compromise CAV network security, posing serious risks for malicious activities. Although several anomaly detection (AD) approaches for CAV networks are proposed, they often fail to: i) detect multiple anomalies in specific sensor(s) with high accuracy or F1 score, and ii) identify the specific sensor being attacked. In response, this paper proposes a novel framework tailored to CAV networks, called CAV-AD, for …

Tuning Selectivity Of Ni/Al2o3 Catalysts In Co2 Hydrogenation By Addition Of N, S-Doped Carbon, Nipitpon Jarumalai

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study investigates the enhancement of Ni/Al₂O₃ catalysts for CO₂ hydrogenation by incorporating nitrogen and sulfur co-doped carbon (NSC). A series of catalysts Ni/Al2O3 and its NSC-modified counterparts (Ni1NSC/Al2O3, Ni3NSC/Al2O3, Ni7NSC/Al2O3, and Ni15NSC/Al2O3) were synthesized via thermal treatment under a nitrogen atmosphere and systematically characterized. Techniques including TGA, Raman spectroscopy, and XPS confirmed successful NSC incorporation. Further structural and surface analysis using TEM, XRD, CO-IR, CO2-TPD, H2-TPD, and H2-TPR revealed that NSC modification influenced Ni dispersion, surface basicity, hydrogen activation, and the electronic state of Ni species. Catalytic performance was evaluated in a fixed-bed reactor under a CO2:H2 ratio of …

Effects Of Endomycorrhizal Fungi On Lemon Balm Plant Growth, Makenzie Boylston, Katie L. Davis, Emily L. Garner, Jackson Whiteside, Angela D. Panvini

Science University Research Symposium (SURS)

Mycorrhizal fungi benefit plants by enhancing nutrient uptake through the plant roots in exchange for sugars from the plant itself. There are two main types: endomycorrhiza, and ectomycorrhiza. Endomycorrhizal fungi form symbiotic relationships with plant roots, which can enhance nutrient uptake, stress resistance, and overall plant growth. This study aimed to determine the effects of endomycorrhizal fungi on the growth and development of Melissa officinalis (lemon balm), a medicinal herb known for its antimicrobial and calming properties. A control group of six plants with no fungal fertilizer and an experimental group of six plants inoculated with endomycorrhizal fungal fertilizer were …

The Protective Role Of Melanin Within The Teleost Inner Ear, Gabriel Heckerman

Mahurin Honors College Capstone Experience/Thesis Projects

Melanin is the dark pigment responsible for influencing the color of bodily structures, and it is variably present throughout human and animal tissue. Melanin is also found within the mammalian inner ear, and it has been observed that a lack of melanin is associated with greater susceptibility to sensorineural hearing loss. In this study, melanin levels of the inner ears of different color morphs of the fish species Poecilia latipinna and Cyprinus carpio were measured and the potential protective role of that melanin from acoustical stress was examined. Previous research showed that black morphs of both species exhibited less noise-induced …
