Border inspections in a dual-language, second-grade classroom in the U.S. Midwest
… at a 50-50 Dual Language (DL) school in the U.S. Midwest. The image of the border was used as a metaphor to represent the barriers and oppressive acts faced by Mexican immigrant children and their families far removed from the actual México-U.S. geographical border. The study had two purposes: a) …

How to better retain teachers in one-way K-12 language immersion programs
… with a more monolingual culture (i.e. the U.S. Midwest, western Canada) (Rocque, 2014). One-way immersion programs are an understudied part of immersion education that has become more prevalent, and this researcher argues, needed around the globe. Hence, the main focus of this research study is …

Climate Change and Farmer Mental Health: A Participatory and Systems-Based Approach
… Despite local and global reliance on U.S. Midwest farmers' mental health and wellbeing, there are limited studies elucidating the impacts of our changing climate on their mental health. The proposed dissertation addresses this gap by leveraging qualitative data from community stakeholders …

Nitrous oxide from denitrification: Influence of field management, environmental conditions, and nutrient availability
… identified spring thaw N2O emissions in the U.S. Midwest and a connection between denitrification functional genes and potentials. Since denitrification was the major contributor of N2O emissions in my work, I then specifically targeted N2O emissions from denitrification to assess factors driving …

Balancing water quality, nitrogen management, and corn production goals in Illinois
… cropping systems across much of the U.S. Midwest. However, applied N can also increase N losses through nitrate-nitrogen (NO3-N) leaching and nitrous oxide (N2O) emissions, negatively impacting water and air quality, respectively. Given these competing demands, there is a pressing need to …

Cold side thermal energy storage system for improved operation of air cooled power plants
… using 2011 transient price data from the U.S. Midwest Region results in a small increase in annual income. The increased income from the proposed cold side TES system is found to be insufficient to outweigh the required capital investment at current electricity prices.

Evaluation of 4 cycles of S1 recurrent selection in BSP1 and BSP2 popcorn populations
… across seven environments throughout the U.S. Midwest. Regression estimates revealed that popping expansion increased 0.64 cc g−1 (or 1.63%) cycle−1 for the BSP1 population, 0.61 cc g−1 (or 1.52%) cycle−1 for the BSP2 population, 0.65 cc g−1 (or 1.64%) cycle−1 for the population cross, BSP1 x …

Accelerated breeding for winter wheat profitability in a wheat-soybean double-crop system
… wheat (Triticum aestivum L.) (SRWW) in the U.S. Midwest is frequently produced in a wheat–soybean (Glycine max L.) double-crop system, where profitability depends on combining high grain yield with acceptable test weight and sufficiently early maturity to enable timely soybean planting. This …
