Journal ArticleDOI
Persistence, Engagement, and Migration in Engineering Programs
Matthew W. Ohland,Sheri Sheppard,Gary Lichtenstein,Ozgur Eris,Debbie Chachra,Richard A. Layton +5 more
TL;DR: The authors found that engineering students are typical of students in other majors with respect to: persistence in major; persistence by gender and ethnicity; racial/ethnic distribution; and grade distribution, concluding that engagement is a precursor to persistence.
Journal ArticleDOI
Outcomes of a Longitudinal Administration of the Persistence in Engineering Survey
Ozgur Eris,Debbie Chachra,Helen L. Chen,Sheri Sheppard,Larry H. Ludlow,Camelia Rosca,Tori Bailey,George Toye +7 more
TL;DR: This paper found that parental and high school mentor influences as a motivation to study engineering, as well as confidence in math and science skills, were identified as correlates of persistence and intention to complete an engineering major was also a correlate of persistence; it appears to decline sharply at least two semesters prior to students leaving engineering.
Journal ArticleDOI
Fluoride Treatment Increased Serum IGF-1, Bone Turnover, and Bone Mass, but Not Bone Strength, in Rabbits
Charles H. Turner,L. P. Garetto,A. J. Dunipace,Wu Zhang,M. E. Wilson,Marc D. Grynpas,Debbie Chachra,R. McClintock,Munro Peacock,George K. Stookey +9 more
TL;DR: Fluoride's effects on bone mass and bone turnover were not mediated by PTH, and IGF-1 was increased by fluoride and was associated with increased bone turnover, but was not correlated with bone formation markers.
A Preliminary Analysis Of Correlates Of Engineering Persistence: Results From A Longitudinal Study
Ozgur Eris,Debbie Chachra,Helen L. Chen,Camelia Rosca,Larry H. Ludlow,Sheri Sheppard,Krista Donaldson +6 more
TL;DR: This article found that non-persisters are more likely to be motivated to study engineering by external (family) influences, are less confident in their math and science skills, and less engaged in their studies than persisters.
Journal ArticleDOI
The effect of fluoride treatment on bone mineral in rabbits.
TL;DR: The effect of high doses of fluoride on the strength and stiffness of bone may be mediated by its effect on bone mineral, which suggests that the mechanical properties of bone were adversely affected.
