American Journal of Agricultural Economics, EarlyView.Abstract This study examines the impact of soil erosion on agricultural land values in the United States (US) Midwest. Based on a novel county‐level panel data set with information on soil erosion levels and agricultural land values covering five census years (1997, 2002, 2007, 2012, and 2017), we separately investigate the direct effect of two types ...

State-space average modelling of converters with parasitics and storage-time modulation [PDF]
, 1980 The State-Space Averaging approach to modelling switching converter power stages is used to extend the analytical descriptions of the buck, boost, buck-boost, and Cuk converters to included the effects of all parasitic resistances and transistor storage ...

American Journal of Agricultural Economics, EarlyView.Abstract This paper derives a firm‐level threshold, the Herfindahl Neutral Point, from the standard concentration index used in merger review. At this threshold, a marginal expansion leaves the index unchanged. Firms below the threshold reduce concentration when they expand; firms above it increase concentration.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Post‐harvest agricultural residues in Latin America are commonly underutilized, leading to greenhouse gas emissions and lost opportunities for bio‐based value creation. This study tests the hypothesis that decentralized, farmer‐scale pyrolysis technologies can deliver comparable agronomic benefits while exhibiting distinct techno‐economic and ...

Circuit for clamping bridge overvoltages in voltage-fed quasi-Z-source converter [PDF]
, 2016 Unlike the voltage source converter, the Z-source converter can boost as well as buck the input voltage. However, the presence of physically large components in the impedance network introduces large parasitic inductances into power device commutation ...

British Educational Research Journal, EarlyView.Abstract The intersection of economic conditions and early years education has long been debated, particularly where financial constraints shape educational practice and professional realities. Türkiye, characterised by high inflation and structural vulnerabilities in purchasing power parity, provides a critical context for examining how economic ...

Powering Transparency: Global Drivers of Sustainability Reporting in the Electricity Sector
Business Strategy and the Environment, EarlyView.ABSTRACT We examine the drivers of sustainability reporting quality (QSR), conceptualised along two complementary dimensions, relevance and reliability, to assess how firm‐level attributes and institutional conditions jointly shape disclosure practices in the electricity sector.
