Utilizing Markov Chains To Estimate Allele Progression Through Generations, Ronit Gandhi
Utilizing Markov Chains To Estimate Allele Progression Through Generations, Ronit Gandhi
Honors Theses
All populations display patterns in allele frequencies over time. Some alleles cease to exist, while some grow to become the norm. These frequencies can shift or stay constant based on the conditions the population lives in. If in Hardy-Weinberg equilibrium, the allele frequencies stay constant. Most populations, however, have bias from environmental factors, sexual preferences, other organisms, etc. We propose a stochastic Markov chain model to study allele progression across generations. In such a model, the allele frequencies in the next generation depend only on the frequencies in the current one.
We use this model to track a recessive allele …
The Design Of An Agricultural Youth-Centered Rural Development Program In Rwanda, Laetitia Igiraneza Sinyigenga
The Design Of An Agricultural Youth-Centered Rural Development Program In Rwanda, Laetitia Igiraneza Sinyigenga
Honors Theses
Rwanda is primarily a rural, young, and agriculture-based country. The referred variables- agriculture, rural population, and youth- can be creatively merged to engage and empower youth for rural development. This paper indicates the utilization of cross-disciplinary knowledge to design an agricultural youth-centered rural development program in Rwanda. The program uses the interdependence of economic sectors (agriculture and education) with resources (environmental & natural resources and human resources) to boost rural community development. The program’s main activities- mentorship, agribusiness training, tutoring, exposure visits, and community work- highly reflect the requirement for advancing the selected main economic sectors and resources. There is …
Biochar: Properties And Potential Benefits For Agricultural Soil In Rwanda, Andromede Uwase
Biochar: Properties And Potential Benefits For Agricultural Soil In Rwanda, Andromede Uwase
Honors Theses
Physical and chemical soil degradation is becoming a major challenge for agricultural productivity in Rwanda, which is the most important part of the country’s economy. The wide spreading soil degradation in Rwanda is mainly a result of naturally poor soils coupled with unsustainable soil management leading to, for example, accelerated soil erosion, acidification, nutrient loss, compaction, and to decreasing yields. Biochar, as an end product of pyrolysis of biomass in the absence of oxygen, has been proposed as a soil amendment in remediation strategies because of its positive effects on soil productivity relevant parameters such as soil pH, structure, nutrient …
Anthropogenic Change On The Distribution Of Marine Megafauna And Their Prey, Baylie Fadool
Anthropogenic Change On The Distribution Of Marine Megafauna And Their Prey, Baylie Fadool
Honors Theses
Anthropogenic change is impacting the distribution and survival of marine megafauna and their prey. Humans are changing every aspect of the marine environment, with effects reaching as large as changing the composition of marine environments to directly overexploiting species through the fishing industry. The role that marine megafauna play in balancing ecosystems, including as top apex predators, leads to detrimental results in the absences and population declines of these species. Migrations and declines due to threats on marine apex predator species will alter their environments by causing mesopredator release and changes in community structure, which is often associated with reduced …
Quantitative Appraisal Of Non-Irrigated Cropland In South Dakota, Shelby Riggs
Quantitative Appraisal Of Non-Irrigated Cropland In South Dakota, Shelby Riggs
Honors Theses
This appraisal attempts to remove subjectivity from the appraisal process and replace it with quantitative analysis of known data to generate a fair market value of the subject property. Two methods of appraisal were used, the income approach and the comparable sales approach. For the income approach, I used the average cash rent for the region, the current property taxes for the subject property, and a capitalization rate based on Stokes' (2018) capitalization rate formula to arrive at my income-based valuation. For the comparable sales approach, I utilized Stokes' (2018) research in optimization modeling to estimate a market value for …
