Authors:
Isaac D Buck

Seton Hall Law Rev 2019 ;49(1):1-51

University of Tennessee College of Law.

For the better part of a decade, Americans have had a front-row seat to a fervent and turbulent debate over the future of their health care system. The passage of the Patient Protection and Affordable Care Act of 2010 (ACA), the most comprehensive health reform effort since the mid-1960s, ushered in a new era in health law and policy, granting millions of Americans access to health care. After multiple legal challenges and congressional efforts that ultimately failed to slay the law, the ACA had become entrenched by the end of the Obama administration, even though pieces of the law had failed to work exactly as planned.

Chronic stress exposure and daily stress appraisals relate to biological aging marker p16.

Psychoneuroendocrinology 2018 Dec 7;102:139-148. Epub 2018 Dec 7.

Cousins Center for Psychoneuroimmunology, Semel Institute for Neuroscience and Human Behavior, University of California, 300 Medical Plaza, Los Angeles, CA 90095, USA; Department of Psychology, University of California, 502 Portola Plaza, Los Angeles, CA 90095, USA. Electronic address:

Previous research has linked exposure to adverse social conditions with DNA damage and accelerated telomere shortening, raising the possibility that chronic stress may impact biological aging pathways, ultimately increasing risk for age-related diseases. Less clear, however, is whether these stress-related effects extend to additional hallmarks of biological aging, including cellular senescence, a stable state of cell cycle arrest. The present study aimed to investigate associations between psychosocial stress and two markers of cellular aging-leukocyte telomere length (LTL) and cellular senescence signal p16. Read More

Gaze allocation in face-to-face communication is affected primarily by task structure and social context, not stimulus-driven factors.

Cognition 2018 Dec 14;184:28-43. Epub 2018 Dec 14.

Experimental Psychology, Helmholtz Institute, Utrecht University, Utrecht, the Netherlands; Developmental Psychology, Utrecht University, Utrecht, the Netherlands; Brain Center Rudolf Magnus, University Medical Center, Utrecht, the Netherlands.

Gaze allocation to human faces has recently been shown to be greatly dependent on the social context. However, what has not been considered explicitly here, is how gaze allocation may be supportive of the specific task that individuals carry out. In the present study, we combined these two insights.
