Full text linkGender, Victimization, and Delinquency: Examining Gendered Pathways to Crime Among Juveniles
Full text linkThe intersection of gender, crime, and victimization is a critical area of study within criminology, particularly as it relates to understanding the differing pathways men and women take into criminal behavior. Historically, crime statistics have shown a significant male predominance, particularly in violent offenses. Feminist criminology has played an essential role in reframing the narrative around gender and crime, emphasizing the need to examine the gender pathways that shape male and female experiences differently. While men may employ violence more overtly, women often rely on more subtle strategies to navigate criminal activities, avoiding physical confrontation when possible. Feminist criminologists argue that this dynamic reflects broader social structures governing how gender is performed in both legal and illegal activities.
Research revolving around gender and crime is especially important when looking at adolescent substance use because the influence of gender becomes readily apparent and prominent. For this project, data from the Michigan Alcohol and Other Drugs School Survey were utilized. This survey includes 8th, 10th and 12th graders in different schools assessing their experiences with victimization and their engagement with substances. The research in this paper was aimed at examining whether these variables had a relationship, and whether that relationship was different across genders. To assess this, a gamma analysis was run comparing all victimization variables with all delinquency variables. This provided a visualization of the relationships and separated the results by gender
Off the Clock but Still at Work: Investigating the Relationship Between Workplace Incivility and Behavioral Disengagement
Full text linkThis thesis investigated the relationship between workplace incivility and behavioral disengagement, using emotional appraisal as a mediating factor. Data was collected through a survey method via Prolific. Using the transactional model of stress, I hypothesized that experienced incivility will be positively associated with behavioral disengagement as a coping mechanism. Additionally, I hypothesized that emotional appraisal would mediate the relationship between experienced workplace incivility and behavioral disengagement. By using a mediation model to test these hypotheses I aim to increase the understanding of workplace incivility and its negative impacts on individuals and the workplace as a whole. Results of the study do not support a significant relationship between workplace incivility and behavioral disengagement but did find a negative relationship between workplace incivility and emotional appraisal. Trait negative affect was found to have significant correlations with emotional appraisal. Theoretical and practical implications are introduced, along with future directions research could pursue
Dental Health for Mental Wealth : A Comprehensive Analysis of the Underexplored Impact of Oral Health and Behaviors on Neurobiology and Psychological Well-Being
Full text linkThis thesis explores the link between oral health and psychological state, specifically, the effect of oral health on psychological state and how appropriate oral health impacts this relationship. A review of the literature was conducted and studies interpreted within the scope of oral health’s impact on psychological health and detailing some of the pathways proposed for such a link. The literature search was limited to the English language from well-known databases mainly from 2015 to 2025. A few outliers are present to include foundational information.
The effects of oral disease and oral self-care behaviors were dissected through a biochemical perspective, on inflammation, immune responses, oxidative stress, stress response, cortisol effects, and bacteremia, and furthered using psychological measures relating to emotion, behavior, cognition, social fluency, will, and resiliency. A deep-dive into the existing, usually separate, disciplines of research were evaluated together in detailing the drawn connections.
Some subjective viewpoints contained in this narrative evidence synthesis result from my academic and employment backgrounds as a Psychological Sciences Alumna and an Expanded Functions Dental Assistant. The evidence presented shows that behavioral practice of good oral hygiene should be consistent with psychological models of well-being while mitigating the many negative effects of poor oral health care - directly within the mouth and beyond. This could potentially extend to many constructs of life, demonstrating the need for and calling-to-action future research combining psychology relating to well-being with the field of dentistry.
More holistic and effective care of an individual may arise from continued study into the dental to mental health connection as it unfolds
Reliability of a Linear Position Transducer During the Bench Press Across Three Segments
Full text linkInternational Journal of Exercise Science 18(2): 622-635, 2025. The purpose of this investigation was to determine inter-set and inter-session reliability of the HUMAC360 measures for duration (DUR), peak velocity (PV) and mean velocity (MV) across three segments of the bench press. Seventeen recreationally active adults participated in this investigation. During visit one, participants completed a bench press one-repetition maximum (1RM). Visits two and three consisted of two sets of three repetitions at 30%-, 50%-, 60%-, and 70 %-1RM. Segments were defined by dividing total displacement into equal thirds at the bottom (BOT), middle (MID) and top (TOP). Intraclass correlation coefficients (ICC) and standard error of measurement (SEM) were used to assess reliability while paired samples t-tests were used to identify differences between sets or sessions with significance set at p≤0.05. Excellent ICCs were present for PV and MV at most intensities in each segment between sets, while ICCs for DUR varied. MV and PV displayed excellent ICCs at lower intensities across segments between sessions, with decreases at higher intensities, while variable inter- session reliability for DUR was present across intensities and segments. The HUMAC360 reliably measured MV and PV during each segment across sets, though caution is warranted for DUR

The Relationship Between a School Psychologists Workplace Stressors to Their Home Life Functioning
Full text linkSchool psychologists face increasing professional demands due to rising caseloads, paperwork requirements, and staffing shortages, which contribute to elevated levels of occupational stress. Although prior research has examined job-related stress within the profession, little attention has been given to how these stressors may impact practitioners’ personal and home lives. The purpose of this study was to examine how occupational stress experienced by school psychologists relates to stress experienced in their home lives. A total of 176 practicing school psychologists from across the United States completed an anonymous online survey, which included the School Psychologist Distress Inventory (SPDI) and a newly developed home stress scale. The most commonly reported occupational stressors were having too many responsibilities, not enough time to complete job duties, paperwork and documentation requirements, feeling overworked, and high caseloads. Results showed a statistically significant, moderate positive correlation between occupational and home life stress, suggesting that job related pressures often carry over into personal and family domains. An exploratory factor analysis supported a four-factor structure for the home stress scale, although some items did not load clearly and may require revision in future research. These findings highlight the need for both systemic and personal supports to help school psychologists manage stress and maintain well-being in both their professional and personal lives
MECHANOCHEMICAL INVESTIGATION OF THE SOLID-STATE REDUCTION OF METAL OXIDE SPECIES
Full text linkRedox reactions are commonly performed in aqueous solutions. Mechanochemistry offers an alternative route to conduct these reactions in the absence of a solvent. The current research project investigates the feasibility of performing solid-state redox reactions using mechanochemistry as a means to initiate. Utilizing a Wig-L-Bug, sodium metavanadate and vanadium(V) oxide are milled with various inorganic and organic reducing agents. Zn, Mg, Na2SO3, ascorbic acid, and benzoic acid were selected due to the agents’ high reduction potential and ability to reduce vanadium(V) species in acidic or basic solutions. The use of X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) allows for the characterization of the milled products. Additionally, the lanthanoid oxides of ytterbium(III) oxide and europium(III) oxide are milled with Mg. The extent of the reduction for each metal oxide was investigated by varying the milling times. The current research has demonstrated the feasibility of using mechanochemistry to perform solid-state reduction of NaVO3, V2O5, and Eu2O3 utilizing Mg powder in a Wig-L-Bug 30® mixer/grinder
DEPOSITION OF NICKEL/IRON OXIDE CO-CATALYSTS ONTO TITANIUM DIOXIDE TOWARDS WATER PHOTOLYSIS
Full text linkPhotocatalytic water splitting is one potential approach for sustainable hydrogen production, offering an environmentally friendly alternative to fossil fuels. This process typically employs metal–semiconductor hybrid systems, where the semiconductor absorbs sunlight to generate charge carriers, and the metal cocatalyst facilitates charge separation and surface redox reactions. Titanium dioxide (TiO2) is a widely studied semiconductor due to its stability and abundance, but its limited absorption of the solar spectrum requires the incorporation of efficient cocatalysts. Platinum is regarded as the benchmark cocatalyst due to strong proton binding energy that easily facilitates the reduction of water to produce hydrogen gas. However, its high cost and scarcity drive the search for earth-abundant alternatives.
Recent studies have demonstrated that bimetallic Janus-type nanoparticles composed of nickel and iron oxide (Ni-FexOy NPs) can be comparable to platinum’s performance in electrochemical systems. However, Ni-FexOy NPs have not been studied as co-catalysts for photochemical reactions. Here, we synthesized Ni-FexOy-decorated TiO2 nanoparticles via photodeposition, targeting the formation of Fe–O–Ni interfaces and these particles were used in water photolysis reactions. Three synthetic routes were explored: sequential deposition (nickel first, then iron oxide; or iron oxide first, then nickel) and simultaneous deposition of both metals. We also synthesized platinum-decorated TiO2 nanoparticles to use for comparison. The nanoparticles were characterized using transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), inductively coupled plasma optical emission spectroscopy (ICP-OES), and powder X-ray diffraction (XRD), confirming successful surface decoration without altering TiO2 crystallinity.
Photocatalytic performance was evaluated for TiO2 with and without co-catalysts under 300 W xenon lamp illumination and reaction conditions were optimized. Gas evolution was measured volumetrically with an eudiometer, and gas concentrations were evaluated using a NIST calibrated hydrogen analyzer and gas chromatography (GC). While GC analysis is ongoing due to technical issues, preliminary results suggest that these Ni-FexOy co-catalysts result in significantly more gas evolution per unit time than bare TiO2. Future work will involve completing gas chromatography measurements, optimizing reaction pH, and exploring the effect of sacrificial reagents. This research provides preliminary evidence for using Ni-FexOy co-catalysts in place of platinum for solar-driven hydrogen generation
