Maria Luisa Paz, an undocumented' woman who worked in a factory in her native Columbia, is employed by a commercial laundry, Sparrow Linens, together with 300 other workers from El Salvador, the Dominican Republic, and other Latin American countries. Their work consists of disinfecting, washing, pressing, and folding mounds of hospital linens. Paz's job is(More)
Background: The occurrence of multi-directional sliding motion between total knee replacement bearing surfaces is theorized to be a primary wear and failure mechanism of ultra-high molecular weight poly(ethylene) (UHMWPE). To better quantify the tribologic mechanisms of this cross-shear wear, the MAX-Shear wear-testing system was developed to evaluate(More)
For a common class of finite-time heat transfer processes, we derive optimal heating and cooling strategies for minimizing entropy generation. Solutions pertain to a generalized heat transfer law, and are illustrated quantitatively for cases of practical interest, including Newtonian and radiative heat transfer. Optimal paths are compared with the common(More)
A novel experimental paradigm and a novel modelling approach are presented to investigate oscillatory human motor performance by means of a key concept from condensed matter physics, namely, thermodynamic state variables. To this end, in the novel experimental paradigm participants performed pendulum swinging movements at self-selected oscillation(More)
The United States fills the lowest-wage ranks of its labor market with immigrants. Even in the wake of a global recession, once thought likely to result in a high level of return migration, a staggering 7.8 million undocumented workers remain in the labor force. Over 200,000 low-wage guest workers labor on farms and in short-term jobs, tied by law to the(More)
This Article advances a new approach to understanding the relationship between work and citizenship that comes out of research on African American and Latino immigrant low-wage workers. Media accounts typically portray African Americans and Latino immigrants as engaged in a pitched battle for jobs. Conventional wisdom suggests that the source of tension(More)
