Persuasive communication, financial incentives, and social norms: Interactions and effects on behaviors.

Social norms and financial incentives are both known to shape the decisions people make about prosocial actions. This paper reviews the financial incentives in normative systems (FINS) model, which integrates theories of social norms from communication, social psychology, and behavioral economics to predict relationships among incentives, norms, and behaviors. It addresses how incentives can affect norms and how they change the effects of norms on behaviors.

Quantitative detection of tetracycline residues in honey by a simple sensitive immunoassay.

Tetracyclines (TCs) are widely used for prevention and control of infectious diseases and have a great activity against variety of Gram-positive and Gram-negative bacteria. Due to the widespread use of TCs in animal husbandry, it can lead to an increase the risk of TCs remaining in human food. To protect consumers, many countries have set acceptable tolerance levels for these drugs.

Competitive enzyme-linked immunosorbent assay for the determination of catecholamine, dopamine in serum.

A competitive enzyme-linked immunosorbent assay for dopamine (DA) has been optimized and characterized. DA is sensitive to oxygen and light according to a function of the pH on the DA oxidation process. The phenolic groups in DA are readily oxidisable to a quinoid form and thus, free DA deteriorates in alkaline media.
