Thinking About Complexity In Latin America: Contributions Of Neutrosophy In Dialogue With Edgar Morin, Noel Batista-Hernández, Maikel Yelandi Leyva-Vázquez, Alenna Rosa Batista-Barallobre

Neutrosophic Sets and Systems

Smarandache’s neutrosophic logic—and its broader philosophical umbrella of MultiAlism, which insists that any assertion must be considered together with its neutral and anti-assertive counterparts—offers powerful methodological tools to operationalize Edgar Morin’s complexity thinking. While Morin contributes the principles of dialogic, recursiveness and the hologrammatic approach, his continental framework can be difficult to apply empirically. Neutrosophy and MultiAlism formalize contradiction, uncertainty and multidimensionality, thereby bridging theory and practice. In Latin America, where complexity thinking is widely adopted to address realities marked by inequality and instability, this integration enables rigorous modelling of non-linear phenomena. Applications such as Neutrosophic QCA (NsQCA), Neutrosophic Cognitive …

Colonization-Persistence Trade-Offs In The Human Microbiome, Liam F. Nokes

Environmental Studies Senior Theses

Understanding how diverse microbial taxa coexist in the human body without competitively excluding one another remains a key challenge in microbiome ecology. One proposed explanation is the colonization-persistence trade-off, where species with high colonization ability are poor persisters, and vice versa. We test for this trade-off across human associated microbial communities among many individuals and in multiple body sites using a large-scale participant-level meta-analysis of longitudinal microbiome datasets curated from the MGnify database. We applied island biogeography-based models to calculate effective colonization and persistence rates for microbial families and genera across 606 individuals over twenty-six studies. Regression of the log-transformed …
