Results of routine testing of organic food for agro-chemical residues

This report was presented at the UK Organic Research 2002 Conference. Consumers expect organic foods to be free of agro-chemical residues. Organix Brands plc. routinely test organic food ingredients for agrochemical residues using independent test laboratories. In the past year 243 batches of ingredients were tested and low levels of agro-chemical residues were found in 21% of samples. These residues can arise in organic food through environmental contamination, processing contamination or even the fraudulent use of agro-chemicals on organic food. Food containing agro-chemical residues can enter the organic system because of limitations in the organic rule

Is the response of output to monetary policy asymmetric? evidence from a regime-switching coefficients model

This paper investigates regime switching in the response of U.S. output to a monetary policy action. We find substantial, statistically significant, time variation in this response, and that this time variation corresponds to "high response" and "low response" regimes. We then investigate whether the timing of the regime shifts are consistent with three particular manifestations of asymmetry by modeling the transition probabilities governing the switching process as a function of state variables. We find strong evidence that the regime shifts can be explained by whether the economy is in a recession at the time the policy action was taken. In particular, policy actions taken during recessions seem to have larger effects than those taken during expansions. We find much less evidence of any asymmetry related to the direction or size of the policy action. (Formerly titled: "When Does Monetary Policy Matter?

Complementarity in Wormhole Chromodynamics

The electric charge of a wormhole mouth and the magnetic flux ``linked'' by the wormhole are non-commuting observables, and so cannot be simultaneously diagonalized. We use this observation to resolve some puzzles in wormhole electrodynamics and chromodynamics. Specifically, we analyze the color electric field that results when a colored object traverses a wormhole, and we discuss the measurement of the wormhole charge and flux using Aharonov-Bohm interference effects. We suggest that wormhole mouths may obey conventional quantum statistics, contrary to a recent proposal by Strominger.Comment: 12 pages and 2 figures, phyzzx, CALT-68-188
