Status politics is the origin of morality policy.

After drawing a distinction between "class" and "status," an early but short-lived sociological literature on status politics is reviewed. That approach has lost favor, but moral foundations theory (MFT) offers a new opportunity to link morality policy to status politics. While any of the five moral foundations (care, fairness, loyalty, authority, sanctity) can provoke conflict over status, most often sanctity is the cause of status politics because it engages the emotion of disgust.

Disgust sensitivity and support for immigration across five nations.

Immigration has become a focal debate in politics across the world. Recent research suggests that anti-immigration attitudes may have deep psychological roots in implicit disease avoidance motivations. A key implication of this theory is that individual differences in disease avoidance should be related to opposition to immigration across a wide variety of cultural and political contexts.

Bone marrow stromal cell-mediated tissue sparing enhances functional repair after spinal cord contusion in adult rats.

Bone marrow stromal cell (BMSC) transplantation has shown promise for repair of the spinal cord. We showed earlier that a BMSC transplant limits the loss of spinal nervous tissue after a contusive injury. Here, we addressed the premise that BMSC-mediated tissue sparing underlies functional recovery in adult rats after a contusion of the thoracic spinal cord.

Robust CNS regeneration after complete spinal cord transection using aligned poly-L-lactic acid microfibers.

Following spinal cord injury, axons fail to regenerate without exogenous intervention. In this study we report that aligned microfiber-based grafts foster robust regeneration of vascularized CNS tissue. Film, random, and aligned microfiber-based conduits were grafted into a 3 mm thoracic rat spinal cord gap created by complete transection.

Bone marrow stromal cells elicit tissue sparing after acute but not delayed transplantation into the contused adult rat thoracic spinal cord.

Bone marrow stromal cells (BMSC) transplanted into the contused spinal cord may support repair by improving tissue sparing. We injected allogeneic BMSC into the moderately contused adult rat thoracic spinal cord at 15 min (acute) and at 3, 7, and 21 days (delayed) post-injury and quantified tissue sparing and BMSC survival up to 4 weeks post-transplantation. BMSC survival within the contusion at 7 days post-transplantation was significantly higher with an acute injection (32%) and 3-day delayed injection (52%) than with a 7- or 21-day delayed injection (9% both; p < 0.
