Long Panel Studies Of Small-Scale Rural Societies In The Global South: What Is Their Value, Why Are They Rare, And Suggestions To Make Them Happen, Jonathan Bauchet, Ricardo Godoy, William R. Leonard, Victoria Reyes-Garcia, Asher Y. Rosinger, Susan Tanner, Eduardo A. Undurraga

Department of Agricultural Economics Faculty Publications

Many topics in the behavioral sciences and epidemiology require researchers to directly observe entities (e.g., individuals, households) over a long time to identify lasting effects. Long-term panel data collection is more common in high-income countries than in small-scale rural societies (SSRS) of low-income countries. SSRS are mobile, nature-dependent, linguistic minorities, and highly autarkic. Analyzing such data using a life-course perspective can help uncover patterns that align or upend what we know from high-income countries. This study a) reviews long (>∼10 year) panels in SSRS (n = 9), b) extends the analysis to cover somewhat comparable societies of smallholders (n …

A Hedonic Analysis Of Farm Tractor Auction Prices, Madison Pearson, Chad Fiechter, Andy Campbell

Department of Agricultural Economics Faculty Publications

Used farm machinery values play a critical role in farm management and in assessing the financial health of the agricultural sector. However, the heterogeneity of machines, particularly regarding embedded technology and usage, complicates efforts to isolate the factors that influence prices. This study leverages a detailed dataset from Tractor Zoom to estimate the effects of machine characteristics and market conditions on auction prices of used 300 to 450 horsepower tractors. We find a nonlinear relationship between machine usage and price: tractors with fewer than 500 hours of use lose approximately 118⁢𝑝⁢𝑒⁢𝑟⁢𝑎⁢𝑑⁢𝑑⁢𝑖⁢𝑡⁢𝑖⁢𝑜⁢𝑛⁢𝑎⁢𝑙⁢ℎ⁡𝑜⁢𝑢⁢𝑟,𝑤⁢ℎ⁡𝑖⁢𝑙⁢𝑒⁢𝑡⁢𝑟⁢𝑎⁢𝑐⁢𝑡⁢𝑜⁢𝑟⁢𝑠⁢𝑤⁢𝑖⁢𝑡⁢ℎ⁡𝑚⁢𝑜⁢𝑟⁢𝑒⁢𝑡⁢ℎ⁡𝑎⁢𝑛⁢10,000⁢ℎ⁡𝑜⁢𝑢⁢𝑟⁢𝑠⁢𝑠⁢ℎ⁡𝑜⁢𝑤⁢𝑜⁢𝑛⁢𝑙⁢𝑦⁢𝑎⁢𝑤⁢𝑒⁢𝑎⁢𝑘⁢𝑙⁢𝑦⁢𝑠⁢𝑖⁢𝑔⁡𝑛⁢𝑖⁢𝑓⁡𝑖⁢𝑐⁢𝑎⁢𝑛⁢𝑡⁢𝑑⁢𝑒⁢𝑐⁢𝑙⁢𝑖⁢𝑛⁢𝑒⁢𝑜⁢𝑓⁡𝑎⁢𝑏⁢𝑜⁢𝑢⁢𝑡2 per hour.

Short-day onions are typically planted in November-December in the Deep South of the U.S. for spring harvest.   Intermediate day onions start bulbing when the photoperiod is 12-14 hours.  Intermediate day onions are planted in the spring in the Mid-Atlantic region. …

Effect Of Prefilmer Design On Atomization Behavior In The Pre-Vaporization Tube Of A Small-Scale Annular Gas Turbine Combustior, Amogh G. Natu, Antoine M. Fradet, Cohen Nunes, Daniel R. Guildenbecher

School of Mechanical Engineering Faculty Publications

This work investigates the influence of internal prefilmer geometry on fuel spray atomization in the prevaporization tube (PVT) of a small-scale reverse-flow annular gas turbine combustor. Four configurations are examined: a control with no prefilmer, a planar internal prefilmer, and two angled internal prefilmers at θ = 60◦ and θ = 45◦ . Double-pulsed digital in-line holography (DIH) is used to measure droplet size distributions, spray density, Sauter mean diameter (SMD), and droplet velocities at the PVT exit under conditions scaled to represent nominal ignition conditions. Results show the control design exhibits poor atomization characterized by large droplet diameters, low …
