Low-Level Estrogenic Effects At the NIEHS-sponsored "Estrogens in the Environment II" conference held in Washington, DC, last winter, the issue of estrogenic chemicals in the environment and their possible adverse effects on reproduction was addressed. Estrogens are hormones that induce estrus and are responsible for the development and maintenance of female secondary sex characteristics. Chemi...

(2002a, 183) distinguishes the following four putative uses or senses of 'knowledge': (1) Knowledge = belief (2) Knowledge = institutionalized belief (3) Knowledge = true belief (4) Knowledge = justified true belief (plus) 1 (1) and (2) he characterizes as " loose " uses or senses of 'knowledge'; by 'loose', he means " an extended, technical use that departs from the standard, colloquial senses...

The spatial power spectrum of the HI 21 cm intensity in the Small Magellanic Cloud (Stanimirovic et al.1999) is a power law over scales as large as those of the SMC itself. It was interpreted as due to turbulence by Goldman (2000) and by Stanimirovic & Lazarian (2001). The question is whether the power spectrum is indeed the result of a dynamical turbulence or is merely the result of a structur...

Marlene Goldman suggests in her paper "Representations of Buddhism in Ondaatje's Anil's Ghost" that at first glance Ondaatje appears to promote the idea of a Sri Lankan Buddhist faith as transcending history. Ondaatje introduces the subject of Buddhism early on in the novel, emphasizing initially the devastation wrought by imperial and colonial forces. Goldman, however, argues that subsequent r...

In the current issue of Circulation, Gupta et al1 describe a new model for the prediction of cardiac risk after noncardiac surgery. The authors note that perioperative myocardial infarction varies considerably from patient to patient and from procedure to procedure and is associated with very significant morbidity and mortality. The thrust of their argument is that, if patients at higher risk f...

Recent investigations into biological locomotion have resulted in the development of reduced order templates that emphasize the role of lateral dynamics in achieving rapid and robust fore-aft movement, such as the Full-Goldman model for dynamic climbing and the Lateral Leg Spring model for horizontal plane running. The observation of individual animals demonstrating locomotion via both of these...

Goldman presented a method for computing a versor form of the perspective projection of points in the conformal model. His method starts with a view direction and distance to the projection plane, and constructs the eye point from that information. He then uses a rotor to rotate the eye to the origin. In this paper, an alternate construction using transversion for perspective projection is give...

On the basis of the ideas of Goldman and Beja(1980) and Chiarella(1992), we construct a stochastic model of speculative dynamics that has a stochastic equilibrium. In this model, different expectations for the price of fundamentalists and chartists are introduced into the model. The system is analyzed using concepts and techniques from the theory of Random dynamical systems. The model exhibits ...
