Adapting Network Theory For Spatial Network Externalities In Agriculture: A Case Study On Hemp Cross-Pollination, Jeffrey S. Young, Tanner J. Mccarty
Adapting Network Theory For Spatial Network Externalities In Agriculture: A Case Study On Hemp Cross-Pollination, Jeffrey S. Young, Tanner J. Mccarty

Growers have increasingly expressed frustration over the negative externalities created by their neighbor's production practices. These spatial agricultural network problems include issues such as cross-pollination and herbicide drift. We develop novel methods for estimating parameters that allow us to adapt and apply general network diffusion models to these spatial agricultural network problems. Doing so allows us to calculate externality damage within a region and calculate cost-effective policies for alleviating that externality. We empirically illustrate, motivate, and test this approach by applying it to hemp. We find that network structure is an important factor in externality size and cost-effective policy response …
Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young
Measuring Palatability As A Linear Combination Of Nutrient Levels In Food Items, Jeffrey S. Young
Faculty & Staff Research and Creative Activity
It well known that palatability and nutritional quality of foods and/or diets are viewed as being in tension with one another. While there exist multiple measures of healthiness, there are no such measures for tastiness. This gap limits the degree to which researchers can investigate this tension and its implications for dietary behavior and hence public health and nutrition policy. The scope of future work concerning the dietary behavior of Americans would expand greatly if researchers better understood consumers’ willingness to eat certain foods, which matters as much as recommending those foods for them to eat in the first place. …
Science Of Climate Change In Agricultural Courses, Iin P. Handayani
Science Of Climate Change In Agricultural Courses, Iin P. Handayani
Faculty & Staff Research and Creative Activity
Climate change adaptation is required knowledge for students and graduates from colleges of agriculture since recent crop production and food security are influenced by climate change. Thus, understanding the dynamics of climate change is important to support farmers to adapt to future conditions. However, not all students and graduates understand the concept and application of climate change with regard to the dynamics of food production and future food security. While agriculture faces the challenge of climate change adaptation, agricultural courses have not kept pace by incorporating climate change science into the curricula. To address this issue, eleven syllabi in selected …
The Viability Of Selected Potassium Solubilizing Rhizobacteria In A Mixture Of K-Feldspar And Organic Matter As Carrier Material, Diyan Herdiyantoro, Tualar Simarmata, Mieke R. Setiawati, Nenny Nurlaeny, Benny Joy, Mahfud Arifin, J S. Hamdaniand, Iin P. Handayani
The Viability Of Selected Potassium Solubilizing Rhizobacteria In A Mixture Of K-Feldspar And Organic Matter As Carrier Material, Diyan Herdiyantoro, Tualar Simarmata, Mieke R. Setiawati, Nenny Nurlaeny, Benny Joy, Mahfud Arifin, J S. Hamdaniand, Iin P. Handayani

The potassium solubilizing biofertilizer based on selected potassium solubilizing bacteria (KSB) can facilitate availability of potassium in primary silicate minerals containing potassium to be absorbed by the plants. The key to successful application of biofertilizer in showing positive effects on inoculated plants is the selection of a carrier material that can guarantee viability of inoculants during shelf life before being applied in the field. The purpose of this study was to determine viability of three selected KSB isolates which were formulated in a mixture of K-feldspar (KF), rice straw compost (RSC), rice husk biochar (RHB), and Aleksandrov liquid medium (ALM) …

Conversion of deforested areas into oil palm plantation has been suggested as a means to improve soil quality and carbon sequestration capacity in forest margin areas. Soil organic carbon fractions, such as particulate organic carbon is the most sensitive indicator in improving soil organic matter and soil quality. We determined particulate organic matter - carbon (POM-C) and mineral associated carbon (MAC) in Bengkulu and West Java Provinces Indonesia. The study areas were grain crop fields, secondary forest, 5 yr-oil palm plantation, 10 yr-oil palm plantation, 15 yr-oil palm plantation and 25 yr-oil palm plantation. Soil organic carbon fraction magnitudes varied …
Low Income And Access To Healthy Food: The Case Of Milk, Jeffrey Young, James K. Binkley
Low Income And Access To Healthy Food: The Case Of Milk, Jeffrey Young, James K. Binkley

Even with abundant dietary research and knowledge about healthy eating, there is still a considerable shortfall in dietary quality of low-income households in the US. Chen et al. (2012) proposed that this problem is at least in part due to low-income individuals’ having less expected future earnings and thus, reduced incentive to pursue longevity by means of healthy eating. We further their analysis, offering improvement by controlling for access to low-fat milk. We find that even when allegedly crucial factors such as cost and access are not issues, relative purchasing of low-fat milk is still linked to higher income.
