Utilizing Creative Writing Techniques In First-Year Composition, Brett Moss
Utilizing Creative Writing Techniques In First-Year Composition, Brett Moss
Student Theses and Dissertations
One common issue found in first-year composition courses is a lack of emphasis on creative style and writing about writing (WAW) concerns. This thesis is concerned primarily with explaining how creative writing skills can benefit students in first-year composition courses, as well as advocating for more WAW ideas. I argue that by allowing students the chance to write with a more creative mindset in an environment which consciously considers writing as a skill, not just in the English department but across disciplines, a greater understanding of the importance of writing can be gained, along with more transfer skills.

Remote Sensing Of Seismic Signals Via Enhanced Moiré-Based Apparatus Integrated With Active Convolved Illumination, Adrian A. Moazzam, Anindya Ghoshroy, Durdu Güney, Roohollah Askari
Michigan Tech Publications
The remote sensing of seismic waves in challenging and hazardous environments, such as active volcanic regions, remains a critical yet unresolved challenge. Conventional methods, including laser Doppler interferometry, InSAR, and stereo vision, are often hindered by atmospheric turbulence or necessitate access to observation sites, significantly limiting their applicability. To overcome these constraints, this study introduces a Moiré-based apparatus augmented with active convolved illumination (ACI). The system leverages the displacement-magnifying properties of Moiré patterns to achieve high precision in detecting subtle ground movements. Additionally, ACI effectively mitigates atmospheric fluctuations, reducing the distortion and alteration of measurement signals caused by these fluctuations. …

Let's Talk About Sex, Baby! Gender Roles In Parent-Child Sexual Communication, Alexandra Henrici
Dissertations and Theses
Parent-child sexual communication remains a fruitful avenue to increase safe sex behaviors, which are currently in decline by today's adolescents. Historically, mothers have reported engaging in parent-child sexual communication more than fathers do. Previous scholarship suggests this difference could be due to traditional gender role beliefs or conflicts with traditionally masculine attributes. Using social cognitive theory and social role theory, this study conducted a cross-sectional survey on parents of children aged 9 through 16. Positive relationships existed between outcome expectations, self-efficacy, and level of detail in sexual and reproductive health conversations between parents and children. Though no statistical difference was …
