The public’s awareness of noise and vibration forms a significant barrier to further development of railways. This chapter begins with a short introduction to the main fundamental aspects of acoustics, including decibels, frequency analysis, the propagation of sound with distance and common measurement quantities. The main sources of railway noise are discussed, including rolling noise, impact noise, curve squeal and aerodynamic noise. Simple calculation procedures are described that can be used to assess the impact of railway noise and to compare it with legal limits. The final section is devoted to ground vibration, which is a related form of environmental disturbance.

As recent events in the Middle East and North Africa suggest, nonviolent revolutionary movements may represent an oppressed population's most promising path to ridding itself of an authoritarian regime. But as the diverging experiences of Tunisia and Egypt on the one hand, and Libya, Syria, Bahrain, and Yemen on the other suggest, nonviolent victory is never a foregone conclusion. This chapter seeks to contribute to our understanding of nonviolent revolutionary success through an analysis of one of the world's first nonviolent revolutions, that of Iran in 1977–1979. Based on historical evidence, I argue that friendly international relations between the United States and Iran is a key factor in explaining both the revolutionaries’ preference for nonviolent tactics and the government's inability to repress the movement. Jimmy Carter's human rights framework served as an important incentive for revolutionaries to remain nonviolent while ensuring that state repression of unarmed protesters would come at a political price high enough to discourage the government from resorting to overwhelming violence.

Public administration as an aspect of governmental activity has existed as long as political systems have been functioning and trying to achieve program objectives set by the political decision-makers. Public administration as a field of systematic study is much more recent. Advisers to rulers and commentators on the workings of government have recorded their observations from time to time in sources as varied as Kautilya's Arthasastra in ancient India, the Bible, Aristotle's Politics, and Machiavelli's The Prince, but it was not until the eighteenth century that cameralism, concerned with the systematic management of governmental affairs, became a specialty of German scholars in Western Europe. In the United States, such a development did not take place until the latter part of the nineteenth century, with the publication in 1887 of Woodrow Wilson's famous essay, “The Study of Administration,” generally considered the starting point. Since that time, public administration has become a well-recognized area of specialized interest, either as a subfield of political science or as an academic discipline in its own right.

This paper explores the interface between institutional theory and Austrian theory. We examine mainstream institutionalism as exemplified by D. C. North in his work with Wallis and Weingast on the elite compact theory of social order and of transitions to impersonal rights, and propose instead an Austrian process-oriented perspective. We argue that mainstream institutionalism does not fully account for the efficiency of impersonal rules. Their efficiency can be better explained by a market for rules, which in turn requires a stable plurality of governance providers. Since an equilibrium of plural providers requires stable power polycentricity, the implication goes against consolidating organized means for violence as a doorstep condition to successful transitions. The paper demonstrates how to employ Ostroms’ Bloomington School Institutionalism to shift, convert, and recalibrate mainstream institutionalism's themes into an Austrian process-oriented theory.
