Putting Care Back into Health Care: An Analysis of the Place of Community Health Workers within the U.S. Health Care System

This paper explores who a Community Health Worker (CHW) is and contextualizes the social, political, and historical factors that allowed for the growth of CHWs within the primary health care sector in the U.S. It analyzes how CHWs perceive their own roles and responsibilities within the U.S. health system as a means of highlighting the gap within health care services and the influence of Social Determinants of Health (SDH) on well-being. The second part of this paper relates CHWs to scholarship by medical anthropologist Paul Farmer and public health scholar Alicia Yamin concerning pathologies of power and the need for national health care reform initiatives that prioritize health as a human right. I suggest how the concept of a CHW informs current perceptions of well-being and health in terms of SDH and embodies the action needed to shift health as a human right social movements from theory to reality

Method of forming silicon structures with selectable optical characteristics

Silicon and metal are coevaporated onto a silicon substrate in a molecular beam epitaxy system with a larger than stoichiometric amount of silicon so as to epitaxially grow particles of metal silicide embedded in a matrix of single crystal epitaxially grown silicon. The particles interact with incident photons by resonant optical absorption at the surface plasmon resonance frequency. Controlling the substrate temperature and deposition rate and time allows the aspect ratio of the particles to be tailored to desired wavelength photons and polarizations. The plasmon energy may decay as excited charge carriers or phonons, either of which can be monitored to indicate the amount of incident radiation at the selected frequency and polarization
