Understanding the biology of heifer maturity and its relationship to calving difficulty and subsequent breeding success is a vital step in building abioeconomic model to identify optimal production and profitability. A limited dependent variable probit model is used to quantify the responses among heifer maturities, measured by a maturity index (MI), on dystocia and second pregnancy. The MI account for heifer age, birth BW, prebreeding BW, nutrition level, and dam size and age and is found to be inversely related to dystocia occurrence. On average there is a 2.2% increase in the probability of dystocia with every 1 point drop …

Estimating The Effectiveness Of A Seasonal Gas Tax For Controlling Episodic Pm2.5 Concentrations In Cache County, Utah, Leo A. Moscardini
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cache County, Utah boasts an abundance of awe-inspiring natural beauty. However, at times, its air quality rivals the worst in the United States. During the winter months of December through February, particulate matter measuring two and a half micrometers or less, commonly known as PM2.5, often concentrates to dangerously high levels causing extensive harm to public health. Lawmakers have scrambled to pass legislation aimed at mitigating the risks posed by poor air quality, recently adopting a county-wide vehicle emissions testing program designed to reduce exhaust emissions from on-road mobile sources. However, its efficacy has been hotly debated and many …
