Dimensions of Self-Sufficiency

Computing Efficiency, Sufficiency, and Self-sufficiency: A Model for Sustainability?

Computing is an activity that is based on natural resources like any other human activity. Technological progress has made it possible to perform more and more computations with less material and energy input. This paper looks at this development through the lens of the three concepts of efficiency, sufficiency, and self-sufficiency, asking the question of whether it could lead to a state of se...

Distributional Impacts of the Self-Sufficiency Project

A large literature has been concerned with the impacts of recent welfare reforms on income, earnings, transfers, and labor-force attachment. While one strand of this literature relies on observational studies conducted with large survey-sample data sets, a second makes use of data generated by experimental evaluations of changes to means-tested programs. Much of the overall literature has focus...

Potential for Achieving Tritium Self-Sufficiency

Tritium is the main fuel ingredient in the plasma of MFE and IFE systems based on the D-T fuel cycle. Since tritium is not a naturally existing isotope, attaining tritium selfsufficiency is necessary for self-sustaining fusion plants operating on the D-T fuel cycle. Tritium is bred in a lithium-containing blanket surrounding the plasma. Once tritium is generated, it needs to be collected, proce...

Comparative Advantage, Self-sufficiency and Food Security in Iran: Case Study of Wheat Commodity

Food security has a dynamic notion during the time and may be affected by various domestic and global factors.Nevertheless, Iranian policy makers consider food security as same as self-sufficiency in agricultural food products, particularly wheat production. However, self-sufficiency can contribute to food security only if it is in coincidences with comparative advantage and sustainable resourc...
