CO2 can be good for you!

The role of exercise testing and gas-exchange measurement in the prognostic assessment of patients with heart failure. The study of the effects of noninvasive positive pressure ventilation to reduce chronic compensated CO 2 retention in COPD patients 1 ignores the possible adaptive advantage of " resetting " the Pco 2 to a higher level than normal. As experts in the mechanics of COPD have argue...

Can trade be good for the environment?

We analyze the impact of trade in a differentiated good on environmental policy when there is local and transboundary pollution. In autarky, the (equivalent) pollution tax is set equal to the marginal damage from own emissions. If the strategic policy instrument is a tax, leakage occurs under trade and tends to lower the tax. The net terms of trade effect, due to the exportable and importable v...

Can Market Forces Be Used for Good?

Representations Can Be Good Enough

When working remotely with physical objects obvious problems of reference arise because of the lack of a mutually shared object. Systems aiming to support such work tend to be based on understandings of face-to-face interaction and frequently use video. However, video introduces new interactional problems. This paper describes a field study of remote interaction around objects that is telephone...

Cross-linking can be good

combined oxidase/peroxidase that does the cross-linking, the cuticle separates into distinct layers, resulting in translucent worms that often suffer from massive blisters and defective movement. The clue that the cross-linking enzyme (called Duox for Dual Oxidase) might exist came from studies of phagocyte NADPH-oxidase. The latter enzyme generates bursts of superoxide to effect killing of eng...
