Ulcerative colitis (UC), a major form of inflammatory bowel disease (IBD), is on the rise worldwide. Approximately three million people suffer from IBD in the United States alone, but the current therapeutic options (e.g., corticosteroids) come with adverse side effects including reduced ability to fight infections. Thus, there is a critical need for developing effective, safe and evidence-based food products with anti-inflammatory activity. This study evaluated the antiinflammatory potential of purple-fleshed potato using a dextran sodium sulfate (DSS) murine model of colitis. Mice were randomly assigned to control (AIN-93G diet), P15 (15% purple-fleshed potato diet) and P25 (25% purple-fleshed potato …
Reginald Sutcliffe And The Invention Of Modern Weather Systems Science, Jonathan E. Martin
Reginald Sutcliffe And The Invention Of Modern Weather Systems Science, Jonathan E. Martin
Purdue University Press Book Previews
Despite being perhaps the foremost British meteorologist of the twentieth century, Reginald Sutcliffe has been understudied and underappreciated. His impact continues to this day every time you check the weather forecast. Reginald Sutcliffe and the Invention of Modern Weather Systems Science not only details Sutcliffe’s life and ideas, but it also illuminates the impact of social movements and the larger forces that propelled him on his consequential trajectory. Less than a century ago, a forecast of the weather tomorrow was considered a practical impossibility. This book makes the case that three important advances guided the development of modern dynamic meteorology, …

Aging is associated with increased risk of ocular disease, suggesting that age-associated molecular changes in the eye increase its vulnerability to damage. Although there are common pathways involved in aging at an organismal level, different tissues and cell types exhibit specific changes in gene expression with advanced age. Drosophila melanogaster is an established model system for studying aging and neurodegenerative disease that also provides a valuable model for studying age-associated ocular disease. Flies, like humans, exhibit decreased visual function and increased risk of retinal degeneration with age. Here, we profiled the aging proteome and metabolome of the Drosophila eye and …
The Role Of Variable Rate Technology In Fertilizer Usage, Terry Wayne Griffin, Lavona Traywick
The Role Of Variable Rate Technology In Fertilizer Usage, Terry Wayne Griffin, Lavona Traywick
Journal of Applied Farm Economics
Precision technologies such as variable rate fertilizer applications have been touted as solving production agricultural issues, increasing yields, and improving environmental stewardship. Variable rate technologies have been widely available on farms especially via custom service providers; however, utilization rates of these technologies remain relatively low. Low adoption rates indicate barriers to adoption and an opportunity for market expansion. The degree to which such technologies may reduce the demand for fertilizers will depend on VRT adoption rates.

Differences In The Determinants Of Retirement Preparation Between Farm And Nonfarm Households, Sheri L. Worthy, Travis Mountain, Swarn Chatterjee, Carrie Johnson, Elizabeth Kiss, Barbara O'Neill, Lorna Saboe-Wounded Head, Michael S. Gutter
Journal of Applied Farm Economics
As principal farm operators age, retirement and succession planning has become increasingly important to the U.S. agriculture industry. This study examined differences in the determinants of retirement preparation between farm and nonfarm households using the Survey of Consumer Finances. Factors such as risk preferences, financial capability, human capital, and other demographic characteristics of farmers that may play a role in their decision to plan for retirement were examined. Retirement planning was investigated by running three separate sets of logistic regressions on the overall sample, farm households, and nonfarm households. Likelihood of consulting a financial planner, expecting to leave a bequest, …
Hemp Production Network Effects: Are Producers Tipped Toward Suboptimal Varietal Selection By Their Neighbors?, Tanner Mccarty, Jeffrey Young
Hemp Production Network Effects: Are Producers Tipped Toward Suboptimal Varietal Selection By Their Neighbors?, Tanner Mccarty, Jeffrey Young
Journal of Applied Farm Economics
The 2018 farm bill removed industrial hemp from the Schedule 1 Controlled Substance List. In response, states scrambled to enact hemp legislation. Some hemp flower producers report their hemp fields were cross- pollinated by a neighbor growing a different hemp cultivar. For hemp flower crops, cross- pollination reduces cannabinoid concentration levels within the flower; these concentration levels dictate flower price. We show that in a repeated game, once a sufficiently large percentage of growers decide to plant hemp fiber/seed crops, cross-pollination forces flower growers to convert to fiber/seed to avoid the negative network externality. Over time, a stable, suboptimal Nash …
Cost Efficiency Of International Corn And Soybean Production, Rachel Purdy, Michael Langemeier
Cost Efficiency Of International Corn And Soybean Production, Rachel Purdy, Michael Langemeier
Journal of Applied Farm Economics
The objective of this paper was to examine the cost efficiency of corn and soybean pro-duction for typical farms involved in the cash crop agri benchmark network using data for the period 2013 to 2017. Average cost efficiency for the typical farms in the network that produced corn, soybeans, and both corn and soybeans was 0.749, 0.774, and 0.939, respectively. Inefficiency was a greater problem for the farms producing corn than for the other farm types examined. Inefficient farms tended to overutilize direct, operating, and overhead inputs.

Journal of Applied Farm Economics
Price determinants for bulls, cows, and feeder cattle are well established in the literature but there has been little research on bred heifer price determinants and specifically the impact of feeder cattle prices on the purchase price of bred heifers. We estimated the impact of reproductive characteristics and feeder cattle prices on bred heifer prices for beef production. Data were obtained from a May and November bred heifer sale located in Kentucky and hedonic pricing models were estimated for bred heifers for each sale month. Prices for fall- calving heifers were influenced by number of months bred or expected calving …
Determinants Of Feedlot Cattle Death Loss Rates, Mark Buda, Kellie Curry Raper, John Michael Riley, Derrell S. Peel
Determinants Of Feedlot Cattle Death Loss Rates, Mark Buda, Kellie Curry Raper, John Michael Riley, Derrell S. Peel
Journal of Applied Farm Economics
Death loss in feedlot cattle can have significant impacts on feedlot profitability. Not only does death loss result in foregone revenue, but the operation still incurs the costs to date associated with those animals. This study uses pen-level feedlot data from a private feed-lot in the Southern Great Plains. Both company- owned and customer retained ownership cattle are included in the data set. A Tobit model is used to analyze pen characteristics’ influence on death loss in feedlot cattle, including cattle characteristics, source characteristics, management characteristics, and treatment incidence. Results imply that several pen characteristics impact death loss and that …
Analysis And Prediction Of Californian County Precipitation Using Atmospheric River Indices, Soil Moisture, And Snow Water Equivalent, Avnika Manaktala
Analysis And Prediction Of Californian County Precipitation Using Atmospheric River Indices, Soil Moisture, And Snow Water Equivalent, Avnika Manaktala
Geodata Science Technical Reports
Atmospheric rivers (AR) are long and narrow filaments in the atmosphere that transport water vapor in the lower troposphere. They release water vapor in the form of rain or snow when they make landfall and can therefore be linked to floods in extreme cases. During a year where the Californian region has faced wildfires due to the impacts of climate change, it is pivotal to understand the precipitation patterns as it has major implications towards the surface environment in the region. Soil Moisture and Snow Water Equivalent (SWE) have been found to correlate with AR in the past and this …

Journal of Pre-College Engineering Education Research (J-PEER)
Given the increased attention on pre-college engineering education and its disciplinary nature pertaining to language, discourses, and communicative practices, this state-of-the-art literature review focused on findings of research articles informed by qualitative and quantitative data to foreground communicative literacies within engineering design teams at the pre-college level. A disciplinary literacies framework was used to interpret and analyze published works in this particular domain. A search, selection, and inclusion process typical for state-of-the-art reviews yielded 33 studies. Constant comparison and open-coding led to clustering studies under five overarching themes in ranked order of frequency of occurrence pertaining to: (a) engineering disciplinary …
