The Missing Basics & Other Philosophical Reflections for the Transformation of Engineering Education

The paper starts by reflecting on what senior engineering students don't know how to do when they confront a real-world project in an industrially sponsored senior design project. Seven, largely qualitatively, skills are found to be lacking: questioning, labeling, qualitatively modeling, decomposing, measuring, ideating, and communicating. These skills, some of the most important critical and creative thinking skills in the arsenal of modern civilization, are termed "the missing basics" and contrasted with what engineering faculty usually call "the basics." The paper critically examines the term "the basics" and other terms that are conceptual hurdles to fundamental reassessment of engineering education at this time. The paper concludes that the engineering academy is stuck in a Kuhnian paradigm born in the cold war, that the reflexive belief in the superiority of math, science, and engineering science to the exclusion of other topics is not itself scientific, and that the use of tired code words is not an argument or a rational defense of a paradigm that may have outlived its usefulness. The paper concludes by highlighting the role philosophy can play in clearing away the conceptual confusion, thereby permitting a more reasoned conversation on the needs of engineering education in our times

Remote Sensing and Problems of the Hydrosphere

A discussion of freshwater and marine systems is presented including areas of the classification of lakes, identification and quantification of major functional groups of phytoplankton, sources and sinks of biochemical factors, and temporal and regional variability of surface features. Atmospheric processes linked to hydrospheric process through the transfer of matter via aerosols and gases are discussed. Particle fluxes to the aquatic environment and global geochemical problems are examined

Remote Sensing and Problems of the Hydrosphere. A Focus for Future Research

The underly problems of water quality which are addressable with remote sensors are considered. The chemical, biological, geological, and physical dynamics of natural ecosystems are examined

Credit constraints in the market for consumer durables: evidence from micro data on car loans

We investigate the empirical significance of borrowing constraints in the market for consumer loans. We set up a theoretical model of consumer loan demand, which in the presence of credit rationing implies restrictions on the elasticities of loan demand with respect to the interest rate and the maturity of the loan. We estimate these elasticities and test the theoretical implications using micro data from the Consumer Expenditure Survey (1984-1995) on auto loan contracts. The econometric specification that we employ accounts for important features of the data: selection, censoring, and simultaneity. Our results suggest that credit constraints are binding for some groups in the population, in particular for young and low-income households

Convenient stability criteria for difference approximations of hyperbolic initial-boundary value problems

New convenient stability criteria are provided in this paper for a large class of finite difference approximations to initial-boundary value problems associated with the hyperbolic system u sub t = au sub x + Bu + f in the quarter plane x or = 0, t or = 0. Using the new criteria, stability is easily established for numerous combinations of well known basic schemes and boundary conditions, thus generalizing many special cases studied in recent literature
