Campesino World-Building: Stories Of Migration, Memory, And Care In The Tension Of The Colonial Frame, Chelsea Ríos Gómez

Cal Poly Humboldt theses and projects

Campesinos, often reduced to the label of “farmworkers”, are too often seen only through the lens of their labor within profit-driven systems. This thesis disrupts that limited narrative by illuminating the rich, expansive nature of vivencias campesinas, ways of being that transcend capitalist measures of value. These vivencias are lived, embodied experiences rooted in campesino lifeways, encompassing cultural, spiritual, and relational practices that nurture and sustain life.

My research is guided by four central questions: (1) In what ways have campesinos in pixley resisted exploitative labor systems, and how can this resistance be understood as a form of care labor? …

Autopoietic Energy Transition Towards Clean And Renewable Energy For Developing Countries, Victor Christianto, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

The global economy's reliance on energy supply and distribution necessitates a shift towards clean and renewable energy sources. This article explores how the economies of energy producers and consumers can be better modeled through the lens of autopoiesis, a concept developed by Humberto Maturana and further elaborated by Fritjof Capra (cf. Web of Life). By viewing energy systems as self-producing and self-maintaining entities, we can gain insights into the dynamics of energy transition in developing countries and identify strategies for fostering sustainable and resilient energy ecosystems.
