How Do Different Levels Of Ph Affect The Growth Of Heritage And Regular Radish Plants?, Kathleen Bradie

The International Student Science Fair 2018

The purpose of this experiment was to discover how the pH levels in water affect heritage and regular radish mass. I predicted that if the pH levels are near neutral the plants mass will increase. PH solutions of 3, 5, 7, 9, and 11 were added to my regular and heritage plants over the course of several weeks. After using the pH solutions the radishes were pulled and massed to reveal the results. The results showed that the heritage pH 5 and regular pH 7 radishes grew best.

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Women’S Empowerment In Agriculture And Agricultural Productivity: Evidence From Rural Maize Farmer Households In Western Kenya, Gracious M. Diiro, Greg Seymour, Menale Kassie, Geoffrey Muricho, Beatrice Wambui Muriithi

All Peer-Reviewed Publications

This paper documents a positive relationship between maize productivity in western Kenya and women’s empowerment in agriculture, measured using indicators derived from the abbreviated version of the Women’s Empowerment in Agriculture Index. Applying a cross-sectional instrumental-variable regression method to a data set of 707 maize farm households from western Kenya, we find that women’s empowerment in agriculture significantly increases maize productivity. Although all indicators of women’s empowerment significantly increase productivity, there is no significant association between the women’s workload (amount of time spent working) and maize productivity. Furthermore, the results show heter-ogenous effects with respect to women’s empowerment on maize …
