Use of the World Wide Web in Mathematics Instruction

Many mathematics instructors may find they can use the World Wide Web to distribute information and facilitate discussion and interaction in their classrooms, while actually reducing their administrative workload. Here is a discussion of some of the benefits (including better student understanding!) which an instructor might enjoy from taking the plunge

Chicano Ethnicity and Aging

In an insightful article published a decade ago, The Chicano Aged, David Maldonado offers some comments that are germane to this presentation. In summing up the dilemma of the Chicano elderly, he asserts: The aged person in the extended family holds high status and commands the respect and obedience of the younger family members. Within the extended family structure. the aging person grows in prestige and respect. The individual holds high rank and has influence in the life of the group.[1] This is the position afforded the aged in many societies as long as the elderly are able to function and contribute in a meaningful way. Prestige, respect, and influence are important parts of their role so long as the aged are not perceived as being a burden. There is, however, a stigma attached to aging in the United States because of the emphasis upon youth and a mind set which does not view aging as a positive process

Further evidence of the absence of Replica Symmetry Breaking in Random Bond Potts Models

In this short note, we present supporting evidence for the replica symmetric approach to the random bond q-state Potts models. The evidence is statistically strong enough to reject the applicability of the Parisi replica symmetry breaking scheme to this class of models. The test we use is a generalization of one formerly proposed by Dotsenko et al. and consists in measuring scaling laws of disordered-averaged moments of the spin-spin correlation functions. Numerical results, obtained via Monte Carlo simulations for several values of q, are shown to be in fair agreement with the replica symmetric values computed by using perturbative CFT for the second and third moments of the q=3 model. RSB effects, which should increase in strength with moment, are unobserved.Comment: 7 pages, some minor modifications (mainly misprints). To Appear in Europhysics Letter

Mathematical analysis and simulations of the neural circuit for locomotion in lamprey

We analyze the dynamics of the neural circuit of the lamprey central pattern generator. This analysis provides insight into how neural interactions form oscillators and enable spontaneous oscillations in a network of damped oscillators, which were not apparent in previous simulations or abstract phase oscillator models. We also show how the different behavior regimes (characterized by phase and amplitude relationships between oscillators) of forward or backward swimming, and turning, can be controlled using the neural connection strengths and external inputs
