Tax Policy and Farm Organization

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The Tax Cuts and Jobs Act (TCJA) introduced substantial changes to the tax code, affecting farms' organizational incentives. This study examines farms' responses to the TCJA along extensive and intensive margins, focusing on organizational and labor expense adjustments.

Changes in membrane fatty acids of a halo-psychrophile exposed to magnesium perchlorate and low temperatures: Implications for Mars habitability

Frontiers in Astronomy and Space Sciences, 2023
The presence of perchlorate salts in aqueous solutions bears two opposite effects on habitability. On the one hand, perchlorate salts trigger a decrease in the freezing point of the aqueous solutions, resulting in stable aqueous solutions at subzero ...

Ultrathin cellulose ester films: preparation, characterization and protein immobilization [PDF]

, 2010
In this study cellulose acetate butyrate (CAB) and carboxymehtylcellulose acetate butyrate (CMCAB) films adsorbed onto silicon wafers were characterized by means of ellipsometry, atomic force microscopy (AFM), sum frequency generation spectroscopy (SFG ...

Consumer Valuation of Meat Alternatives and Labeling Policies: A Comparative Perspective

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study investigates and compares US consumer perceptions and the impact of environmental, human health, and animal welfare information related to conventional meat on preferences for meat alternatives and labeling policies. Using the best–worst scaling method across 10 different burger alternatives, our results show that the meat burger is

Structure and magnetism in nanocrystalline Ca(La)B$_6$ films [PDF]

, 2004
Nanocrystalline films of La-doped CaB$_6$ have been fabricated by using a rf-magnetron sputtering. Lattice expansion of up to 6% with respect to the bulk value was observed along the direction perpendicular to the film plane, which arises from the ...

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Polymerization and replication of primordial RNA induced by clay-water interface dynamics

Communications Chemistry
In the study of life’s origins, a key challenge is understanding how RNA could have polymerized and subsequently replicated in early Earth. We present a theoretical and computational framework to model the non-enzymatic polymerization of ribonucleotides ...

Transparent blend of poly (Methylmethacrylate) / cellulose acetate butyrate for the protection from ultraviolet [PDF]

, 2016
The use of transparent polymers as an alternative to glass has become widespread. However,the direct exposure of these materials to climatic conditions of sunlight and heat decrease the lifetime cost of these products.

Do Tax Incentives for Farmland Leases Increase Farm Supply? Evidence From Iowa's Beginning Farmer Tax Credit

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT In recent decades, agriculture has become increasingly concentrated through horizontal mergers and acquisitions via corporate entities, and policy makers are concerned this will be exacerbated by the aging population of farm operators. To reduce market concentration in agriculture, many states have enacted policies to entice new prospective ...
