    The Applied Use of Technology in Phenotyping Apple (Malus × domestica Borkh.) Fruit and Trees
    (2019-07) Anderson, Joshua
    Current phenotyping methods for apple (Malus × domestica Borkh.) fruit and trees are destructive, time and labor intensive and can be subjective. Fruit: A handheld NIR spectrometer was used to collect spectra along with traditional phenotyping of several fruit quality traits. Two trait spectral models (starch pattern index, and soluble solids concentration) had sufficient predictive ability across 15 cultivars. Temperature and outdoor limitations of the spectrometer were minimal compared to the importance of collecting more than a single scan per fruit to control for individual fruit heterogeneity. Trees: A low-cost RGB-D sensor was used to characterize trees of a rootstock experiment. The relationship between image-derived metrics and hand-measured was highest for tree height R2=0.93, and TCA R2=0.71. The predictive ability of cumulative yield by image based-tree volume was lower than by manual-measured tree volume. Tree volume, in general, did not improve upon other mixed models when estimating cumulative yield.

    The Commonwealth of Social Science: The American Social Science Association and a Pragmatist Politics of Expertise
    (2014-09) Anderson, Joshua
    Historians of the social sciences have noted that for the first generation of social scientists in the United States immediately after the Civil War, there was no distinction between politics and scholarship. While this equation has been understood either as an indication of the immaturity of the early social sciences or as a distinctive moment in time that has been lost to history, this dissertation argues that the political relevance of the social sciences does not rest exclusively in their direct advocacy work but in other activities such as constructing audiences to respond to their research and the manner in which that audience is engaged, terms on which the political relevance of the modern social sciences can be understood as well. Using the work of the classical pragmatists (Peirce, James, and Dewey) as an interpretive lens to study one early social scientific organization in particular, the American Social Science Association (ASSA), this dissertation urges an understanding of social scientific knowledge in terms of experiences that are worked upon by diverse audiences through a shared set of practices. Drawing on archives of ASSA documents at Yale University and a reading of the Journal of Social Science, the central claim of the dissertation is that the social sciences have been a political project from their beginning. Both pragmatism and the social sciences emerged at a moment in American history of great uncertainty as well as social and political change. To the degree that these conditions endure, so too do the underlying politics of the social sciences.
