Martin argues that the accepted interpretation of Rousseau's philosophy of education, as revealed in "Emile," is fundamentally mistaken because it fails to acknowledge his discussion of the education of girls. She proposes that Rousseau intended a production and not a growth model which applies to the education of both sexes. (SK)

Of primary importance here, and the basis on which UGMHS was developed, is the method of modeling. The programming language and job type array concept, coupled with the time-step procedures that are applied yield a general simulation capability.

In an attempt to clarify the controversial views about the general validity of the rather frequently and successfully used critical state mode, we consider an explicit formulation of this model and present a careful analysis of the boundaries of the regions where the field B is zero. As a result, it seems that the arguments recently published that call into question the ...

Business managers who look for ways to cut costs face difficult questions about the efficiency and effectiveness of software engineering practices that are used to complete projects on time, on specification, and within budget (Johnson, 1995; Lindstrom & Jeffries, 2004).

We discuss the use of a genetic algorithm (GA) to invert data for many acceptable solutions, in contrast to inversion for a single, 'optimum' solution. The GA is a directed search method which does not need linearization of the forward problem or a starting model, and it can be applied with a very large ...

Data assimilation techniques, such as the Kalman filter (KF) and its extensions, update state variables based on the KF type of algorithms, but state-space models usually have relevant physical laws or settings. The updated states by the KF may violate some physical constraints, which can be equality or inequality, and linear or nonlinear constraints. This paper presents three ...
