Sugar Cube Karst

The purpose of this activity is to explore the way water moves through a porous, soluble substance and to observe the development of pits and channels as the substance dissolves in water. Students learn what karst is and how it is formed. Educational levels: Intermediate elementary, Primary elementary

Making Large Classes Small(er): Assessing the Effectiveness Of a Hybrid Teaching Technology

This paper examines learning outcomes in a one-semester introductory microeconomics course where contact time with the instructor was reduced by two-thirds and students were expected to view pre-recorded lectures on-line and come to class prepared to engage in discussion. Students were pre-and post-tested using the Test of Understanding in College Economics (TUCE - 4). Learning outcomes as measured by the change in test scores are found to be as good as or better than calibrating data for groups assessed using the TUCE - 4. In addition to being a more enjoyable course for the instructor, the course design can be part of a more self-directed curriculum that uses available resources more efficiently to achieve similar learning objectives to a lecture-based introductory course.active learning, assessment, computer-assisted instruction, introductory microeconomics

Women in Law--Equal Justice for All?

This study uses Dr. Barbara Bergmann\u27s Model of Labor Market Overcrowding to test for gender discrimination in the legal profession. Bergmann\u27s model suggests that stereotypes and society\u27s perceptions about what is normal divide male and female lawyers into two separate labor markets such that 1) females are paid less than males and 2) male and female lawyers are segregated into different areas of practice--either by area of concentration or position within the firm. Two samples, one composed of 45 young lawyers and the other consisting of 400 lawyers (200 males and 260 females), are used to test these hypotheses. The results indicate that significant wage differentials do exist for young lawyers--females earn significantly less even after controlling for experience. While there is no significant evidence of crowding in the specific areas of practice, there is statistically significant evidence of crowding with respect to partnership status

CEO Compensation and Firm Performance - Are They Related?

Topics in geometric analysis with applications to partial differential equations

Title from PDF of title page (University of Missouri--Columbia, viewed on September 13, 2010).The entire thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file; a non-technical public abstract appears in the public.pdf file.Dissertation advisor: Dr. Marius Mitrea.Vita.Ph. D. University of Missouri--Columbia 2009.The main aim of the current thesis is to investigate the mathematical tools and methods used to study problems which bridge between analysis and geometry. Such an undertaking is particularly useful in situations in which the geometry is variable, such as: -- the theory of minimal surfaces, in differential geometry -- shape analysis and optimization-- engineering modeling -- (elasticity phenomena for beams, plates, shells, etc) -- free or moving boundary problems -- certain variational problems in partial differential equations A common feature of the above circumstances is that the underlying geometry is the variable one wishes to study. From a historical point of view, the basic principles and methods employed in the treatment of such problems originated in rather distinct fields of applied and theoretical mathematics, and have traditionally evolved on distinct, parallel paths. Our ultimate goal is to provide alternative, conceptually simpler approaches to some of the basic results in these fields.Includes bibliographical reference
