This is the first full-scale discussion of English phonology since Chomsky and Halle's seminal The Sound Pattern of English (SPE). The book enphasizes the analysis using ordered rules and builds on SPE by incorporating lexical and metrical and prosodic analysis and the insights afforded by Lexical Phonology. It provides clear explanations and logical development throughout, introducing rules individually and then illustrating their interactions. These features make this influential theory accessible to students from a variety of backgrounds in linguistics and phonology. Rule-ordering diagrams summarize the crucial ordering of approximately 85 rules. Many of the interactions result in phonological opacity, where either the effect of a rule is not evident in the output or its conditions of application are not present in the output, due to the operation of later rules. This demonstrates the superiority of a rule-based account over output oriented approaches such as Optimality Theory or pr

Why did Egyptian cults, especially those dedicated to the goddess Isis and god Sarapis, spread so successfully across the ancient Mediterranean after the death of Alexander the Great? How are we limited by the established methodological apparatus of historiography and which innovative methods from other disciplines can overcome these limits? In this book, Tomáš Glomb shows that while the interplay of different factors such as the economy, climate, and politics created favorable conditions for the early spread of the Isiac cults, the use of innovative quantitative methods can shed new light and help disentangle the complex interplay of individual factors. Using a combination of geospatial modeling, mathematical modeling, and network analysis, Glomb determines that, at least in the regions of the Hellenistic Aegean and western Asia Minor, the political channels created by the Ptolemaic dynasty were a dominant force in the local spread of the Isiac cults. An important contribution to th

A cognitive ethnography of how bioengineering scientists create innovative modeling methods.In this first full-scale, long-term cognitive ethnography by a philosopher of science, Nancy J. Nersessian offers an account of how scientists at the interdisciplinary frontiers of bioengineering create novel problem-solving methods. Bioengineering scientists model complex dynamical biological systems using concepts, methods, materials, and other resources drawn primarily from engineering. They aim to understand these systems sufficiently to control or intervene in them. What Nersessian examines here is how cutting-edge bioengineering scientists integrate the cognitive, social, material, and cultural dimensions of practice. Her findings and conclusions have broad implications for researchers in philosophy, science studies, cognitive science, and interdisciplinary studies, as well as scientists, educators, policy makers, and funding agencies. In studying the epistemic practices of scientists, Ner

Why do people run for office with opposition parties in electoral authoritarian regimes, where the risks of running are high, and the chances of victory are bleak? In Activist Origins of Political Ambition, Keith Weghorst offers a theory that candidacy decisions are set in motion in early life events and that civic activism experiences and careers in civil society organizations funnel aspirants towards opposition candidacy in electoral authoritarian regimes. The book also adapts existing explanations of candidacy decisions derived from leading democracies that can be applied to electoral authoritarian contexts. The mixed-methods research design features an in-depth study of Tanzania using original survey data, sequence methods, archival research, and qualitative data combined with an analysis of legislators across authoritarian and democratic regimes in Africa.

The American presidency has long tested the capacity of the system of checks and balances to constrain executive power, especially in times of war. While scholars have examined presidents starting military conflicts without congressional authorization or infringing on civil liberties in the name of national security, Stuart Streichler focuses on the conduct of hostilities. Using the treatment of war-on-terror detainees under President George W. Bush as a case study, he integrates international humanitarian law into a constitutional analysis of the repercussions of presidential war powers for human rights around the world.Putting President Bush’s actions in a wider context, Presidential Accountability in Wartime begins with a historical survey of the laws of war, with particular emphasis on the 1949 Geneva Conventions and the Nuremberg Tribunal. Streichler then reconstructs the decision-making process that led to the president’s approval of interrogation methods that violated Geneva’s m

Beginning in the 1870s, migrant groups from Russia's steppes settled in the similar environment of the Great Plains. Many were Mennonites. They brought plants, in particular grain and fodder crops, trees and shrubs, as well as weeds. Following their example, and drawing on the expertise of émigré Russian-Jewish scientists, the US Department of Agriculture introduced more plants, agricultural sciences, especially soil science; and methods of planting trees to shelter the land from the wind. By the 1930s, many of the grain varieties in the Great Plains had been imported from the steppes. The fertile soil was classified using the Russian term 'chernozem'. The US Forest Service was planting shelterbelts using techniques pioneered in the steppes. And, tumbling across the plains was an invasive weed from the steppes: tumbleweed. Based on archival research in the United States, Russia, Ukraine, and Kazakhstan, this book explores the unexpected Russian roots of Great Plains agriculture.

How meaning works―from monkey calls to human language, from spoken language to sign language, from gestures to music―and how meaning is connected to truth.We communicate through language, connecting what we mean to the words we say. But humans convey meaning in other ways as well, with facial expressions, hand gestures, and other methods. Animals, too, can get their meanings across without words. In What It All Means, linguist Philippe Schlenker explains how meaning works, from monkey calls to human language, from spoken language to sign language, from gestures to music. He shows that these extraordinarily diverse types of meaning can be studied and compared within a unified approach―one in which the notion of truth plays a central role. “It’s just semantics” is often said dismissively. But Schlenker shows that semantics―the study of meaning―is an unsung success of modern linguistics, a way to investigate some of the deepest questions about human nature using tools from the empirical a
