    askew
    (2014-05) Wichmann, Stephanie; Jefferson, Corey
    Every moment is everywhere . Being human is a mass of feelings and the felt. One can never be certain who they are moment to moment for the body is always changing and adjusting, along side partners’, time and space. Nothing is constant.

    Future Tense
    (2020) Troyer, Denise; Jefferson, Corey
    Nature - Humans - Past - Future - Presence - Absence These familiar terms are the stepping stones of thought that went into my thesis work. While some may pair these words together as dichotomies, I concentrate on the balancing act that exists between them. Since the first Industrial Revolution beginning in the mid-18th century, human activities have significantly altered the rest of the natural world. Other species have evolved in reaction to circumstances produced by human actions. Through my own observations of nature and research into how humans have impacted nature’s evolution, speculation began to swell as to what does the future look like? My thesis work presents found objects from human life intermingled with my own ceramic pieces that are inspired by nature but have elements of peculiarity. The relics represent a human existence and the ceramic components act as a symbol of other forms of life. These familiar, yet odd growth forms imply futurity, a continued existence. This futurity is stemming from a human element that is clearly from the past, combined with this altered view of nature. Are humans of the past too? Are these growths something of the future? At a fundamental level, the work I make as an artist is intended to imply that life will continue in some form, with or without us. My work evokes a glimpse of how things may evolve in the future in order to stress the importance of mindful consideration of how the decisions we make impact the environment.

    Influence of toothbrush abrasion and surface treatments on the color and translucency of resin infiltrated hybrid ceramics
    (The Korean Academy of Prosthodontics, 2021) Labban, Nawaf; Al Amri, Mohammad; Alhijji, Saleh; Alnafaiy, Sarah; Alfouzan, Afnan; Iskandar, Mounir; Feitosa, Sabrina; Biomedical Sciences and Comprehensive Care, School of Dentistry
    Purpose: The study compared the color change, lightness, and translucency of hybrid resin ceramics exposed to toothbrush abrasion and surface treatment. Materials and methods: Four hybrid ceramics [Lava Ultimate (LU), Vita Enamic (EN), Shofu HC (SH), and Crystal Ultra (CU)] were compared with a glass-ceramic (Vita Mark II) control. One hundred and twenty specimen blocks were prepared using a precision saw machine. Specimens in each material were divided into four subgroups based on the surface treatment (polishing or staining) and a storage medium (water or citric acid). Simulated tooth brushing with a mixture of 100 RDA (radioactive abrasives) with 0.3 ml distilled water was used for 3650 cycles (7300 strokes) for each specimen. Measurements for the color change, lightness, and translucency were measured after toothbrushing using a spectrophotometer. Statistical analysis compared outcomes using paired t-test, ANOVA, and Tukey post hoc test. Results: The maximum color change was identified in SH (stained acid) [1.44 (0.40)], whereas the lowest was identified in EN (polished water) [0.66 (0.16)] material. The maximum and minimum loss of surface translucency was observed in SH (polished water) [12.3 (0.52)] and EN (stained acid) [6.5 (0.55)] specimens, respectively. Lastly, loss of lightness was the highest in VM (polished acid) [69 (0.95)], whereas the lowest was observed in CU (stained water) [56.7 (0.86)]. Conclusion: The comparison presented a significant effect of toothbrush abrasion on translucency and lightness of the hybrid resin ceramics. Color change was not significantly influenced irrespective of the storage medium employed. Surface staining demonstrated the preservation and stability of color and optical properties under the influence of toothbrush abrasion and chemical trauma.

    Pregnant Thoughts
    (2018) VanderHorck, Ruth; Baker, Lesley
    My thesis work explores pregnancy as a lived experience with deep cultural connotations. It looks at aspects of how pregnancy feels and is experienced differently depending on circumstances and perspective. This research uses the pregnant female body to explore issues of difference. The work seeks to create a dialogue with the viewer on issues that are central to resolving inequality in society. Pregnancy, childbirth, childcare, and the necessary cultural support are the focus of the fourth wave of the women’s movement and its continuing push for equity and justice.

    untitled: color body
    (2018) Tesmer, Casey; Baker, Lesley
    My research poses questions to the audience of how people see color on a body, what subconscious preconceptions that comes packaged with, and the ties of those preconceptions to American culture and how that might affect people's actions in society.
