This paper analyzed farmers' willingness to accept (WTA) payment and uncertainties toward carbon market through a 2021 U.S. Midwest farmer survey. The findings showed that farmer carbon supply was elastic at intermediate prices ($20–50/Mg), but inelastic at low ($10–20/Mg) and high ($50–70/Mg) price levels. While perceived co‐benefits play significant roles in promoting participation at low‐price levels, variables such as age, education, farm size, and soil quality are more likely to influence producers' choices at intermediate‐ and high‐price levels. To enhance farmers' support for carbon programs, measures should be taken to improve benefit, while reducing cost and uncertainty. [ABSTRACT FROM AUTHOR]

Stress‐related illnesses are linked to the onset and progression of renal diseases and depressive disorders. To investigate stress‐induced changes in the renal transcriptome associated with the development of depressive behaviors, we generated here a chronic social defeat stress (CSDS) model of C57 BL/6 male mice and then performed RNA sequencing of the kidneys to obtain an inflammation‐related transcriptome. Administration of the antidepressant drug fluoxetine (10 mg·kg−1·day−1) during CSDS induction could partially alleviate renal inflammation and reverse CSDS‐induced depression‐like behaviors. Moreover, fluoxetine also modulated gene expression of stress‐related hormone receptors, including prolactin and melanin‐concentrating hormone. These results suggest that CSDS can induce gene expression changes associated with inflammation in the kidney of C57 BL/6 male mice, and this inflammation can be treated effectively by fluoxetine.

Collector OA, oleic acid, is widely used industrially for fluorite flotation. Low selectivity, dispersibility and collecting capability of the OA collector are always observed. In this study, compared with flotation of dolomite, a collector mixture of OA and SPE (styrylphenol polyoxyethylene ether) demonstrated significantly better performances for the fluorite. An optimal mass ratio 4 : 1 OA : SPE was found, and the recovery of fluorite was increased from over 85 % to more than 94 % compared with pure OA. Furthermore, the dosage of the collector agent was reduced from 50 mg mL−1 to 20 mg mL−1, which did not negatively impact the recovery of dolomite. The results from the contact angle tests indicated that SPE selectively increased the surface hydrophobicity of fluorite but had little effect on dolomite. Besides, zeta potential measurements and IR analyses revealed that the addition of SPE led to strong chemical adsorption on the surface of fluorite, resulting in a significant difference in the flotation performances of the two minerals. Therefore, SPE‐emulsified OA is corroborated to prompt more selectivity and collecting capability on flotation of fluorite over dolomite. [ABSTRACT FROM AUTHOR]

China's currency policy has been criticized for its apparent pursuit of mercantile advantage by artificially stimulating exports, with potential adverse effects on other economies. While China's currency policy may have positive output effects, there may be additional profits or losses. This paper computes the annual and cumulative accounting profits from currency intervention since 1994 when China began its currency intervention. It is shown that profits initially were positive but since 2007 China has lost a massive amount from the currency market. [ABSTRACT FROM AUTHOR]
