Civil societies function because people pay taxes and make charitable contributions to provide public goods. One possible motive for charitable contributions, called "pure altruism," is satisfied by increases in the public good no matter the source or intent. Another possible motive, "warm glow," is only fulfilled by an individual's own voluntary donations. Consistent with pure altruism, we fin...

Fluoropolymer ®lms prepared by radio frequency glow discharge (RF-glow discharge) are of interest as biomaterials coatings. Previous studies focused on hexa ̄uoroethane (C2F6, HFE) and tetra ̄uoroethylene (C2F4, TFE) as the monomer precursor have shown such surfaces to exhibit unique protein binding capabilities. In this study, slow, surface directed deposition of hexa ̄uoropropylene (C3F6, HFP) ®...

Theory commonly posits agents who care both for the level of public good provision and extent to which they personally contribute cause. Simply put, feel “warm glow” from donations make. I discuss a lottery fundraiser conducted in field devised exogenously vary incentive give identify structural parameters warm glow. Estimates suggest that participants claiming glow as their primary motivation,...

Localized electronic recombination processes in donor–acceptor pairs of luminescent materials have been recently modeled using a new kinetic model based on tunneling. Within this model, recombination is assumed to take place via the excited state of the donor, and nearest-neighbor recombinations take place within a random distribution of centers. An approximate semi-analytical version of the mo...

Tagging physical objects to get a link from the physical world into some kind of technology has been done for a long time. The most commonly known is probably the barcodes that is used in five billion scans every day. During a project at Xerox Research Centre Europe in Cambridge, we came across the concept of Glow Tags. It is partly an expansion of the more traditional tags by, from a user pers...

1. In firefly larvae, extracellular recordings from the light organ nerve show that a volley of action potentials elicits a glow of an intact animal. 2. Intracellular recordings from the photocytes show that they respond to nerve stimulation with a slow, graded depolarization which precedes light emission. The depolarization begins about 0-5 s after the nerve is stimulated; it peaks about 1 s a...

1. Pelagia noctiluca responds to galvanic stimulation by a luminescent glow at the anode. If placed near the cathode a secondary glow occurs also on the cathodal side. 2. The luminescent slime of Pelagia when subjected to the galvanic current glows around the cathode. This is referred partly to the movement of hydrogen bubbles, but in the main to the alkali formed at the cathode. 3. The cause o...

The low pressure glow discharges considered in this paper are the hollow cathode (Paschen), and the flat cathode (Grimm). Both discharges have similar voltage—current characteristics which are responsible for their radiation stability. The analytical sample is supplied to the discharge through a sputtering mechanism which provides a stable and non-selective source of particles. Some of the fund...

We show that our recent SU(4) generalized “rishon” composite model for quarks and leptons, augmented either by the hypothesis of breaking of color SU(3) to “glow” SO(3), or by the hypothesis of incomplete color neutralization in very hard processes, leads to an interpretation of the HERA positron-jet events as the production by color gluon exchange, followed by the decay by color gluon emission...
