Coral reef communities can be deleteriously affected by exposure to low levels of anthropogenic contaminants. Sediments in the vicinity of coral reefs serve as a sink (and when resuspended, as a source) for contaminants and provide an integrative measure of low and intermittent exposure. Sediment porewater toxicity tests using gametes and embryos of the sea urchin Arbacia punctulata were employ...

Interleukin (IL) -1, a proinflammatory cytokine, increases in aneurysm, and the IL-1 receptor antagonist (IL-1Ra) modulates IL-1 activity endogenously. We show here that IL-1Ra-deficiency provokes spontaneous femoral artery aneurysm in mice lacking intervention such as surgery or drugs, providing easily attained observation at different ages as well as diminished mortality from operative proced...

In this study we investigated the relation between job performance and voluntary employee turnover for 5,143 exempt employees in a single firm in the petroleum industry. As hypothesized, we found support for Jackofsky's (1984) curvilinear hypothesis as turnover was higher for low and high performers than it was for average performers. Three potential moderators of this curvilinearity were exami...
