Decision Making for Populations
Critical decisions for large populations have conventionally been made top-down, with million-dollar centralized satellites and surveillance tools used to sense events and generate instructions that are enforced on people. The last two years of the pandemic have shown that these methods are …

Effects of Prescribed Burns on Small Mammal Populations with Comments on Houston Toad Populations
… of small mammal (indicator species) and herptile populations between burned (2 trap lines) and unburned (2 trap lines) management units, assessment of vegetation differences between management units, evaluation of survivorship estimates using mark-recapture data, and the eventual incorporation of …

Genetic Sequencing in Healthy Populations
… technology in the standard screening of healthy populations. This brings ethical dilemmas as well, particularly when considering the use of WGS in fetuses, infants, and children. While WGS may be acceptable for use in adults if adequate safeguards are put into place, parents have a moral duty, …

Moral Development in Pilot Populations
<p>Ethical issues are becoming more commonplace in society today and while most industries are taking steps to improve poor ethical decisions through ethics education, aviation is lagging behind in both understanding of ethical issues inherent to the industry and ethics education. In this study …

Aberrant segregation in human populations
Three cases of aberrant segregation in humans were considered. The first was a possible case of non-random assortment of chromosomes and meiotic drive. Separating children of fathers of given heterozygous ABO genotypes into sperm classes (classified by the ABO gene received from the father), for …

Optimal Management Of Biological Populations
The successful management of biological populations is essential to both the world's economic and environmental wellbeing. This includes controlling invasive species and sustainably harvesting biological resources for profit. In the first chapter we consider monitoring programs for the management …

Evolutionary models in structured populations
… studied in infinitely large homogeneous populations where each individual is equally likely to interact with every other individual. However, real populations are finite and characterised by complex interactions among individuals. In this work, the influence of the population structure on …

Metabolic heterogeneity in microbial populations
… rates, and several metabolic phenotypes—subpopulations relying on diverse metabolic pathways. First we use Population FBA in investigating the effects of single cell proteomics data on the metabolic behavior of an in silico E. coli population. We use the latest metabolic reconstruction …

Modelling interstellar extinction in stellar populations
… the colour-magnitude diagrams (CMDs) of stellar populations. The treatment of extinction in standard CMD analyses is to employ constant ratios of extinction in each photometric filter relative to the visual Johnson-V filter, denoted AX/AV in a generic filter X. This work presents a theoretical …

Predictive Learning with Heterogeneity in Populations
… real-world applications is the heterogeneity in populations of data instances, i.e., different groups (or populations) of data instances show different nature of predictive relationships. For example, different populations of human subjects may show different risks for a disease even if they have …

Breeding Waterfowl Populations in South Dakota
… km2 in 1973 and 1974, respectively. Estimated populations based upon these densities were 1,067,500 breeding pairs in 1973 and 439,600 breeding pairs in 1974. The 58.8 percent decrease in the population occurred concurrently with intensification of drought conditions throughout South Dakota in …

Immunogeneic Cell Populations of the Skin
… in situ. A novel method to count dermal cell populations in situ was developed that resulted in the first published quantification of APCs, DDCs, as well as T cells in human dermis. Second, the traditional form of the emigration assay, which selectively enriches vital cells capable of ex vivo …

Genetic Structure of Yonahlossee Salamander Populations.
… of Tennessee, North Carolina, and Virginia, populations of the yonahlossee are considered to be rare and local throughout their range. Genetic differentiation among populations of any species is usually attributable to long-standing, extrinsic barriers to gene flow. Because of their disjunct …

Management of higher populations in maize
… for higher grain yield in maize, high plant populations must be managed to lesson plant competition. Previous research has focused on different management strategies for higher plant densities, mainly row configuration, but rarely a combination of strategies. The initial experiment for the …
