The purpose of the present study was to test the hypothesis that glazing will affect the Weibull modulus or the mean flexural strength of dental porcelain. Four groups (n = 30) of specimens were prepared from feldspathic body porcelain (Vita VMK 68). The specimens were tested in groups: original glazed condition (control), and after grinding separately with 1,000-grit, 600-grit, and 100-grit si...

OF THESIS THE SHORT GRIT SCALE: A DIMENSIONALITY ANALYSIS This study aimed to examine the internal structure, score reliability, scoring, and interpretation of the Short Grit Scale (Grit-S; Duckworth & Quinn, 2009) using a sample of engineering students (N = 610) from one large southeastern university located in the United States. Confirmatory factor analysis was used to compare four competing ...

Interaction between implant surface and surrounding bone influences implant fixation. We attempted to improve the bone-implant interaction by 1) adding surface micro scale topography by acid etching, and 2) removing surface-adherent pro-inflammatory agents by plasma cleaning. Implant fixation was evaluated by implant osseointegration and biomechanical fixation.The study consisted of two paired ...

This research examines the association between student grit and academic achievement in introductory computer programming courses. While several studies have established a link between grit and student success in classes with lower failure rates, this exploratory work is the first to investigate the relationship in courses with high failure rates. Our survey data show that grittier students ear...

Objective The purpose of this study was to examine the relationship of grit as a construct representing perseverance to overcoming barriers and the total number of school absences to academic performance (AP) while controlling for sociodemographics, fitness (i.e., PACER), and Body Mass Index (BMI). Methods Adolescents (N = 397, SD = 1.85; 80.9% females; 77.1% Hispanic) from an urban, minority...

Objective. To determine if Grit-S scores correlate with academic success in a doctor of pharmacy (PharmD) program, as well as the pursuit and attainment of pharmacy postgraduate (residency or fellowship) training. Methods. A 28-item survey was administered to third- and fourth-year (P3 and P4) pharmacy students. Variables queried included Grit-S score, demographics, pharmacy experience prior to...

The importance of intellectual talent to achievement in all professional domains is well established, but less is known about other individual differences that predict success. The authors tested the importance of 1 noncognitive trait: grit. Defined as perseverance and passion for long-term goals, grit accounted for an average of 4% of the variance in success outcomes, including educational att...

Objective: Self-control and grit have become two of the most important variables that explain success in different aspects of people's daily life (Duckworth and Gross, 2014). Self-control promotes delayed gratification and directly influences thoughts, emotions, and impulses. On the other hand, grit enhances the achievement of goals through perseverance even before extreme external circumstance...
