'There just aren't enough hours in the day': the mental health consequences of time pressure.

Abstract: In this paper I examine the association between subjective time pressure and depression and consider whether time pressure mediates the relationship between roles and depression, whether social and economic resources moderate the association between time pressure and depression, and whether time pressure explains gender differences in depression. Results of a telephone survey of 790 respondents indicate that time pressure is significantly associated with distress for men and women, and that subjective time pressure accounts for the significantly higher depression of employed women. Time pressure mediates the impact of housework and the volunteer role among women and it partially explains the differential depression of divorced men. Several resources moderate the impact of time pressure on depression: income among both men and women and perceived co-worker social support among men. Results suggest that the subjective experience of time pressure can be thought of as a potentially important mechanism by which lived experience is transformed into depression. However, in spite of the ubiquity of time pressure in the North American context, the depressing consequences of this subjective experience are not distributed equitably, suggesting that the capacity to manage time pressure and avoid depression may be another benefit associated with strategically advantageous social locations.

Imaging Dynamical Chiral-Symmetry Breaking: Pion Wave Function on the Light Front

Abstract: We project onto the light-front the pion's Poincare-covariant Bethe-Salpeter wave-function, ob- tained using two different approximations to the kernels of QCD's Dyson-Schwinger equations. At an hadronic scale both computed results are concave and significantly broader than the asymptotic distribution amplitude, ' asy (x) = 6x(1 x); e.g., the integral of '�(x)/' asy (x) is 1.8 using the sim- plest kernel and 1.5 with the more sophisticated kernel. Independent of the kernels, the emergent phenomenon of dynamical chiral symmetry breaking is responsible for hardening the amplitude. The momentum-space wave-function for a nonrelativis- tic quantum mechanical system, (p,t), is a probability amplitude, such that | (p,t)| 2 is a non-negative density which describes the probability that the system is de- scribed by momenta p at a given equal-time instant t. Although the replacement of certainty in classical me- chanics by probability in quantum mechanics was dis- turbing for some, the step to relativistic quantum field theory is still more confounding. Much of the additional difficulty owes to the loss of particle number conservation when this step is made: two systems with equal energies need not have the same particle content, because that is not conserved by Lorentz boosts, so that even inter- pretation via probability densities is typically lost. To exemplify: a charge radius cannot generally be defined via the overlap of two wave-functions because the initial and final states do not possess the same four-momentum and hence are not described by the same wave-function.

Atomically and Electronically Coupled Pt and CoO Hybrid Nanocatalysts for Enhanced Electrocatalytic Performance

Abstract: Atomically and electronically coupled Pt and CoO hybrid nanocatalysts are fabricated for electrocatalytic oxygen reduction reaction. The atomic coupling between the Pt and the CoO endows precise control of the atomic interface between the Pt and the CoO, which directly results in electron donation from the CoO to the Pt, and thus favorable tuning of the electronic structure of the Pt.
