OCCUPATION AND ETHNICITY IN FIVE NINETEENTH-CENTURY CITIES: A COLLABORATIVE INQUIRY

Abstract

Literary critics and historians often interpret authors and authors' works as more or less significant, but are reluctant to quantify those works. The interdisciplinary field of creativity studies, however, poses methods of quantifying the eminence of an author's works. This study uses four measures from that field (anthology entries, scholarly citations, entries in books of quotations, and auction sale records) and one measure from the fields of computational linguistics and data mining (ngrams using millions of books digitized by Google) to assess the eminence of John Milton's thirty-one prose works1. For the purpose of this study, Milton's short “A Letter to a Friend Concerning the Ruptures of the Commonwealth” (1659) was not included in the quantitative analysis out of concern with possible conflations and confusions with letters in Milton's Familiar Letters. and their relation to his greater achievement in epic poetry. These measures indicate the singular eminence of Areopagitica, Milton's 1644 tract on the liberty of unlicensed printing.     

An Element of Thought: Phosphorus and Mental Philosophy in the Nineteenth Century

Georges Cabanis (17571808), through his writings on the relation of the physical and moral, or psychological, aspects of man, left a legacy that made the study of mental activity a part of physiology. His views on the importance of phosphorus to the function of the brain thrust that element into a prominent stream of research that involved many investigators in several countries. Although that particular stream eventually dried up, its influence remained: by the beginning of the twentieth century basic medical science had become well set on studies of the mind-body relationship.     

Behavior Factor for Performance-Based Seismic Design of Plane Steel Moment Resisting Frames

Simplified expressions to estimate the behavior factor of plane steel moment resisting frames are proposed, based on statistical analysis of the results of thousands of nonlinear dynamic analyses. The influence on this factor of specific structural parameters, such as the number of stories, the number of bays, and the capacity design factor of a steel frame, is studied in detail. The proposed factor describes the seismic strength requirements in order to restrict maximum storey ductility to a predefined value. Interrelation studies between maximum storey ductility and the Park-Ang damage index are also provided for the damage-based interpretation of the performance levels under consideration. Realistic design examples serve to demonstrate the ability of the proposed factor to convert conventional force-based design to a direct performance-based seismic design procedure.
