The idea that there might be “limits to growth” is a key and contested feature of environmental politics. This chapter outlines the limits to growth thesis, describes and assesses critical reactions to it, and comments upon its relevance today. It argues that, after an initial highpoint in the early 1970s, the thesis declined in importance during the ...

One must acknowledge and even admire the passion that writer and photographer Ann Jones brings to the different causes she embraces as she meanders along the paths of her rather eclectic career, now spanning over three decades. Her first book, Uncle Tom’s Campus (1973), examines how her students, in a predominantly African-American college, were being ...

Global Discourse, 2019
In his fifth-century BCE chronicle of the Graeco-Persian Wars, Herodotus describes a challenge that European scholars have faced for two and a half millennia (Drace-Francis, 2013: 1). Since Antiquity, discussions of just what ‘Europe’ is, descriptively and normatively, have not been resolved and consensus has been reached that multiple ‘Europes’ exist.

We show that within the Gold paradigm for language learning an informer for a superfinite set can cause an optimal MDL learner to make an infinite amount of mind changes. In this setting an optimal learner can make an infinite amount of wrong choices without approximating the right solution.

Electrical Engineering, 1934
The amplification obtainable in a vacuum tube amplifier is limited by the noise in the circuit. Of the various sources of noise the most fundamental and inevitable is thermal agitation of electricity. Other sources are the influence of ions and of shot effect and flicker effect on the current in vacuum tubes, poor contacts, mechanical vibration, and ...

It has been observed that various synchronisation operators underlying the modular design of concurrent systems can be explained as pullbacks in suitable categories of concurrent systems. Here, the boundaries of such approach are investigated. For this purpose we study the issue of completeness in categories of trace monoids. It turns out that (finite)

We study the evolution of partial evaluators over the past fifteen years from a particular perspective: The attempt to prevent structural bounds in the original programs from imposing limits on the structure of residual programs. It will often be the case that a language allows unbounded numbers or sizes of particular features, but each program (being ...
