Mathematical Reflections: Standing On The Shoulders Of Giants, Karl J. Smith
Mathematical Reflections: Standing On The Shoulders Of Giants, Karl J. Smith
ACMS Conference Proceedings 1987
The layperson's response to mathematics is often that of desperation. When we tell people our occupation, do we more often than not hear about their unpleasant experiences with mathematics. They often tell us, "I studied algebra in high school and haven't used it since!" Indeed, that may be true. However, we can reply, "How many times has algebra been used on you?" We are all restricted, and protected, by the formulas of mathematics. In the mysterious metaphors we have agreed to cal mathematics, all creation is involved, from the symbol-happy logician down to the cunning geometers, the bees. When I …
Observations On Mathematics And The Christian Faith, W. David Laverell, Carl J. Sinke
Observations On Mathematics And The Christian Faith, W. David Laverell, Carl J. Sinke
ACMS Conference Proceedings 1987
There is little doubt that mathematicians are becoming more concerned with the foundations on which their discipline rests, the meaning of their work, and the philosophical stance implicit in what they do. This concern is prompted by serious questions which have been raised in recent years, questions dealing with the nature of mathematical truth, the nature of proof, certainty (or lack thereof) in mathematics, and the relationship of mathematics to the physical world. This has been particularly true for those of us involved in teaching since it is apparent that good mathematics education cannot ignore these issures.

The Role Of Computer Science In A Liberal Arts College, Russell C. Bjork
The Role Of Computer Science In A Liberal Arts College, Russell C. Bjork
ACMS Conference Proceedings 1987
The question the panel has been asked to discuss actually encompasses two related, but distinct, questions - each of which, in turn, has two subquestions.
The first question concerns the place of a computer science as a major program of study among the offerings of a liberal arts college. The two subquestions here are as follows: First, is computer science an appropriate field of study to offer in a liberal arts college? (Is it a liberal art?) Second, is a liberal arts college an appropriate home for a computer science program? (Can a high quality program be offered in such …

Rise To Power Of Senator Joseph R. Mccarthy: Reflections Of The Cold War Mccarthy Era In American Film, Scott Lainer
Honors Theses
The common bond between much of the film industry and Joseph McCarthy was insecurity and the drive for national approval. If one grasps the specific characteristics of McCarthy the man, and the methods of these politically "inspired" movies, we can to better place the period into context and acknowledge the fact that, if the citizenry is not aware, and is again caught by an ever-building wave of trickle down sentiment, the 1950s might not prove to be an isolated period in American history. Insecurity was not a fifties novelty. It still exists, and could potentially escalate anti-Communist policy and sentiment …

If μ1, ... ,μn are non-atomic probability measures on the same measurable space (S, F), then there is an F-measurable partition {Ai }ni = 1 of S so that μ1 (Ai )≥ (n – 1 + m)–1 for all i=1, ..., n, where m = ∥ Δni=1 μi∥ is the total mass of the largest measure dominated by each of the μi's; moreover, this bound is attained for all n≥1 and all m in [0, 1]. …

We prove that if a class in the cohomology of the mod 2 Steenrod algebra is υn-periodic in the sense of [10[, then its root invariant must be υn+1-periodic, where υn denotes the nth generator of π∗(ΒΡ).
Least-Change Secant Updates Of Non-Square Matrices, Samih Kassem Bourji
Least-Change Secant Updates Of Non-Square Matrices, Samih Kassem Bourji
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In many problems involving the solution of a system of nonlinear equations, it is necessary to keep an approximation to the Jacobian matrix which is updated at each iteration. Computational experience indicates that the best updates are those that minimize some reasonable measure of the change to the current Jacobian approximation subject to the new approximation obeying a secant condition and perhaps some other approximation properties such as symmetry.
All of the updates obtained thus far deal with updating an approximation to an nxn Jacobian matrix. In this thesis we consider extending most of the popular updates to the non-square …

Logic And Proof For Mathematicians: A Twentieth Century Perspective, Calvin Jongsma
Faculty Work Comprehensive List
If there is one aspect of mathematics education that frustrates both students and teachers alike, it has got to be learning how to do valid proofs. Students often feel they really know the mathematics they're studying but that their teachers place some unreasonably stringent demands upon their arguments. Teachers, on the other hand, can't understand where their students get some of the wacky arguments they come up with. They argue in circles, they end up proving a different result from what they claim, they make false statements, they draw invalid inferences - it can be quite exasperating at times! Unfortunately, …
Comparative Instructor Attitudes Toward College Level English And Mathematics Experiences For Gifted High School Students, Bruce Vickers
Comparative Instructor Attitudes Toward College Level English And Mathematics Experiences For Gifted High School Students, Bruce Vickers
Masters Theses & Specialist Projects
Samples derived from a mailed questionnaire were compared. The sample represented high school, community college and university instructors of mathematics and English. The Kentucky public schools sampled were equally represented among high school, community colleges and universities. The research indicated that of those instructors sampled a very high percentage (97.7%) feel that those high school students shown to be academically gifted would benefit from a college experience before high school graduation. The attitudes of those instructors sampled indicated that multiple criteria – grades, recommendations, standardized test scores and personal interview – were considered the preferred method of selection (82.5%). The …

Suppose μ1, ..., μn are probability measures on the same measurable space (Ω, F). Then if all atoms of each μi have mass α or less, there is a measurable partition A1,..., An of Ω so that μi(Ai) ≥ Vn(α) for all i = 1, ... , n, where Vn(•) is an explicitly given piecewise linear nonincreasing continuous function on [0, 1]. Moreover, the bound Vn(α) is attained for all n and all α. Applications are given to L1 spaces, to …
Periodic Phenomena In The Classical Adams Spectral Sequence, Mark Mahowald, Paul L. Shick
Periodic Phenomena In The Classical Adams Spectral Sequence, Mark Mahowald, Paul L. Shick
Mathematics and Computer Science
We investigate certain periodic phenomena in the classical Adams spectral sequence which are related to the polynomial generators υn in π∗(ΒΡ). We define the notion of a class α in ExtΑ(Ζ/2,Ζ/2) being υn-periodic or υn-torsion and prove that classes that are υn-torsion are also υκ-torsion for all κ such that 0 ≤ κ ≤ n. This allows us to define a chromatic filtration of ExtΑ(Ζ/2,Ζ/2) paralleling the chromatic filtration of the Novikov spectral sequence Ε2-term …

Gromov formulated and proved a very general Smale - Hirsch - Phillips type theorem. The theorem concerns the claseification of a class of cross-sections o of a smooth fibre bundle E X over a non-closed manifold X such that each r-jet j(0) satisfies an openness condition as well es a stability condition. Briefly, the openness condition is that each j(a) is a cross-section of some preacribed open subbundle of the bundle of r-jets of local oross- sections of EX, and. the etability condition is that this subbundle remain invarient under the action of the paeudogroup of local diffeo- morphisme of …

Multisectoral Model Of Income Distribution Poverty And Growth:Some Policy Exercies For Indian Economy., Debdas Bandyopadhyay Dr.
Multisectoral Model Of Income Distribution Poverty And Growth:Some Policy Exercies For Indian Economy., Debdas Bandyopadhyay Dr.
Doctoral Theses
The extent of poverty in any country depends upon two factors vlz, the average level of income anxd the degree of inequality in its distribution. The central theme in the continuing debate on the relationship between growth and poverty is whether past growth process in the developing countries has caused any signi.licant benefit to the poor. Kuznets (1955) was first to observe from cross country data that procosa of development is likely to be accompanied by increase in inequality, whhich would reverse itself only at a relatively advanced stage. This hypothesis has been subsequently confirned to some extent by several …

A Generalization Of Lyapounov's Convexity Theorem To Measures With Atoms, John Elton, Theodore P. Hill
A Generalization Of Lyapounov's Convexity Theorem To Measures With Atoms, John Elton, Theodore P. Hill
Research Scholars in Residence
The distance from the convex hull of the range of an n-dimensional vector-valued measure to the range of that measure is no more than α n/2, where α is the largest (one-dimensional) mass of the atoms of the measure. The case α = 0 yields Lyapounov's Convexity Theorem; applications are given to the bisection problem and to the bang-bang principle of optimal control theory.
