Student Perceptions Of Rules For Classroom Interaction, Hanson Paul Leblanc Iii

LSU Master's Theses

ABSTRACT

Burgoon’s expectancy violation model posits that nonverbal rule violations will be evaluated according to the perceptions toward the violator and the behavior itself. However, the violator may have perceptions regarding the appropriateness of the rule. This study measured the perceptions of high school students regarding the rules for classroom interaction. It is believed that the rules for classroom interaction are rules which have been learned through the process of socialization and enculturation into the classroom setting throughout students’ careers. These rules should be well known by all students by the time they reach tenth grade, the grade being investigated. …

Mixed Messages: Reading Contemporary U.S. Literature Of Biracial Girlhood, Candice Nicole Hale

LSU Doctoral Dissertations

The tragic mulatta character is no longer an accurate representation of biracial female characters in literature. This dissertation considers the vast history of the tragic mulatto genre and its tragic and mired representations of biracial women and how they are often portrayed in literature. Within a historical, legal, and political analysis, I highlight the ways perceptions, attitudes, and representations about biracial individuals have changed, so those same shifts should change in the literature. Because of the bourgeoning field of Critical Mixed Race Studies (CMRS), both scholars and authors are recasting and rewriting the narratives and discourses of mixed-race in the …

Review Of The Validity And Feasibility Of Image-Assisted Methods For Dietary Assessment, Christoph Höchsmann, Corby K. Martin

Clinical Research Faculty Publications

Accurately quantifying dietary intake is essential to understanding the effect of diet on health and evaluating the efficacy of dietary interventions. Self-report methods (e.g., food records) are frequently utilized despite evident inaccuracy of these methods at assessing energy and nutrient intake. Methods that assess food intake via images of foods have overcome many of the limitations of traditional self-report. In cafeteria settings, digital photography has proven to be unobtrusive and accurate and is the method of choice for assessing food provision, plate waste, and food intake. In free-living conditions, image capture of food selection and plate waste via the user’s …

Experiences Of Transgender Men Who Joined National Pan-Hellenic Council Sororities Pre-Transition, Sydney Epps

LSU Doctoral Dissertations

The National Pan-Hellenic Council (NPHC) - affectionately known as The Divine Nine - are places of support and leadership development for students. However, these groups espouse traditional gender role themes that align with sexual orientation and gender rigidity. This paper explores how four NPHC members negotiate their identity as both nonbinary or transgender, and Greek. Using the narrative inquiry approach, the researcher will explore how sorority members who no longer identify as cisgender women are treated post-gender transition by other sorority members.

Fluid-Driven Fracture Initiation From Oil And Gas Wells Considering Lifetime Stresses, Andreas Michael

LSU Doctoral Dissertations

Fluid-driven fracture initiation from oil and gas wells is examined in detail. The dissertation covers three subtopics: drilling, completion (stimulations), and post-blowout capping-induced fracture initiation.

Drilling-induced tensile fractures (DITFs) are located in an azimuth orthogonal to wellbore breakouts and are observed from image logs obtained during drilling operations. Fully analytical criteria for the orientation of DITFs initiating from wells in porous, permeable media are derived considering fluid infiltration from a pressurized wellbore. DITF orientation (longitudinal or transverse-to-the-wellbore) is used to constrain the magnitude of the local maximum horizontal principal stress. The range of the possible stress states is indicated on …
