Interdisciplinary medical social work: a working taxonomy.

Findings from a year-long exploratory study aimed at describing universal functions of medical social work with interdisciplinary teams in acute care settings are reported here. A universal taxonomy of interdisciplinary social work skills and competencies was empirically identified through a participatory action research framework. Findings support previous conceptual descriptions of medical social work's overarching and historical role to help interdisciplinary teams in acute care to consider patients' home environment, knowledge, beliefs, culture, and resources during assessment, treatment, and discharge planning.

The Effects of Maternal Separation on Adult Methamphetamine Self-Administration, Extinction, Reinstatement, and MeCP2 Immunoreactivity in the Nucleus Accumbens.

The maternal separation (MS) paradigm is an animal model of early life stress. Animals subjected to MS during the first 2 weeks of life display altered behavioral and neuroendocrinological stress responses as adults. MS also produces altered responsiveness to and self-administration (SA) of various drugs of abuse including cocaine, ethanol, and amphetamine.

Pulsar recoil by large-scale anisotropies in supernova explosions.

Assuming that the neutrino luminosity from the neutron star core is sufficiently high to drive supernova explosions by the neutrino-heating mechanism, we show that low-mode (l=1,2) convection can develop from random seed perturbations behind the shock. A slow onset of the explosion is crucial, requiring the core luminosity to vary slowly with time, in contrast to the burstlike exponential decay assumed in previous work. Gravitational and hydrodynamic forces by the globally asymmetric supernova ejecta were found to accelerate the remnant neutron star on a time scale of more than a second to velocities above 500 km s(-1), in agreement with observed pulsar proper motions.
