Identification of Fatty Acids in Bacillus cereus

10.1K
We propose a protocol to identify fatty acids without the need to purify them. It combines information on the retention times with the mass spectra of three types of fatty acid derivatives: fatty acid methyl esters (FAMEs), 4,4-dimethyl oxazoline derivatives (DMOX), and 3-pyridylcarbinyl esters (picolinyl).

Myocardial Infarction and Functional Outcome Assessment in Pigs

28.6K
This protocol describes the porcine myocardial infarction (MI) model using a 90 min closed-chest coronary balloon occlusion of the left anterior descending artery (LAD), followed by reperfusion. Furthermore, the protocol for several outcome parameters, such as cardiac function, hemodynamics, microvascular resistance, and infarct size, are also...

Summary

This commentary challenges May's view of moral psychology. It argues that many "pessimists" are actually optimistic about moral inquiry progress.

Area of Science:

  • Moral Psychology
  • Philosophy of Mind
  • Ethics

Background:

  • Commentary on "Regard for Reason in the Moral Mind" by May.
  • Addresses May's categorization of interdisciplinary moral psychologists as "pessimists".

Purpose of the Study:

  • To re-evaluate the optimism levels of moral psychologists categorized as "pessimists" by May.
  • To argue that these psychologists hold more optimistic views on moral inquiry progress than May suggests.

Main Methods:

  • Critical analysis of May's arguments and classifications.
  • Interpretation of the stated positions of various interdisciplinary moral psychologists.

Main Results:

  • Many psychologists labeled "pessimists" by May exhibit significant optimism regarding moral inquiry.
