Addressing Health Care Disparities: A Radical Perspective and Proposal
This paper begins by rethinking the sociological theory that social conditions are fundamental causes of health disparities and that controlling disease ironically increases or creates them.

This article explores how material objects reveal patterns of remembrance in the public histories of the nineteenth-century New Zealand Wars fought between British regiments and colonial forces and Māori hapū and iwi (tribal groups). It is based

On the creation of a photon by an electromagnetic wave ball
Recent literature has shown, theoretically as well as experimentally, that while a beam splitter does not split a single photon, it nonetheless divides the electromagnetic wave into transmitted and reflected, with both containing energies.

The gravitational interaction of light is analyzed considering its dual characteristic nature, i.e., as an (electromagnetic) wave or as a particle (photon). Considered as an electromagnetic wave, the light can be source of gravitational waves belonging to the larger class of exact solutions of Einstein field equations which are invariant for a non ...

Controlling Light Harvesting with Light [PDF]
When exposed to intense sunlight, all organisms performing oxygenic photosynthesis implement various photoprotective strategies to prevent potentially lethal photodamage. The rapidly responding photoprotective mechanisms, occurring in the light-harvesting pigment-protein antennae, take effect within tens of seconds, while the dramatic and potentially ...

Contrefaire l’art ou contrefaire la nature : l’analogie artistique pour la restauration écologique
Andrew Light examines the debates on restoration ecology between Robert Elliot and Eric Katz. Rather than taking on their strong metaphysical distinction between nature and culture, as some critics do, he assumes it is true and then argues that it does ...

Light by light diffraction in vacuum [PDF]
We show that a laser beam can be diffracted by a more concentrated light pulse due to quantum vacuum effects. We compute analytically the intensity pattern in a realistic experimental configuration, and discuss how it can be used to measure for the first time the parameters describing photon-photon scattering in vacuum.
