Abstract:This article is about how a very specific section of the Rio Grande was transformed through human intervention over the course of the twentieth century. Geographically, I focus on the stretch of river between and around the twin border towns of El Paso, Texas and Ciudad Juárez, Chihuahua. This is an important area of analysis not only because of the historic importance of the urban complex to U.S.-Mexico relations, but also because it is a desert. I analyze two major river (...) engineering projects, one in the 1930s, the other in the 1960s, as well as the transformation of the water itself due to increased toxicity beginning in the 1990s. In sum, the river was straightened, completely relocated, lined in concrete, and poisoned. No other place on the entire international divide underwent such extreme changes. I explain this by arguing that both political forces and environmental conditions combined to produce such totalizing interventions in the riverine ecosystem. I also argue that these processes reversed the age-old meaning of water in the desert. Historically, water in the desert has been associated with life and biodiversity, but over the course of the twentieth century the desert section of the Rio Grande border was converted into a deadened zone.

A course of lectures delivered at Cambridge in the summer of 1953. They include pieces by Moore, Broad, and Ryle. Körner's "Some Types of Philosophical Thinking" and Ryle's "The Theory of Meaning" are especially stimulating; the book as a whole presents an absorbing picture of contemporary British philosophy.--A.

New technology has a prominent place in the theory and practice of innovation, but the association between high tech and innovation is not inevitable. In this paper, we discuss six metaphorical heroes of agricultural innovation, starting with the dominant hero of frontier science and technology. At first sight, our six heroes can be divided in those who are pro- and those who are anti-technology. Yet in the end technology, and more specifically GM technology, does not emerge as the main issue. (...) Empowering the poor, finding solutions for urgent climate problems, and enhancing the quality of our daily relations to food and the environment – these are the issues the heroes are fighting for. Relations between innovation and technology are better seen as a matter of pragmatic consideration, we will argue. (shrink)

Iphigenia at aulis presents many problems to the literary and textual critic. Among these the problem of the prologue is as clear-cut as it is controversial. It may be summarized as follows: Our text opens abruptly with an anapaestic dialogue between Agamemnon and the Retainer, instead of the usual monologue in trimeters.In reply to a question from the Retainer, Agamemnon launches into a long iambic narrative, describing much that the Retainer must know already, and with no sign, for more than (...) sixty lines, that the Retainer is being addressed. Moreover 49 {Ἐγ⋯νοντο ۸ήδαι…) reads like the first line of a conventional opening monologue. (shrink)

Fractal time fluctuations of the spectral “1/f” form are universal in natural self-organizing systems. Neurobiology is uniquely infused with fractal fluctuations in the form of statistically self-similar clusters or bursts on all levels of description from molecular events such as protein chain fluctuations, ion channel currents and synaptic processes to the behaviors of neural ensembles or the collective behavior of Internet users. It is the thesis of this essay that the brain self-organizes via a vertical collation of these spontaneous events (...) in order to perceive the world and generate adaptive behaviors. REM sleep, which coalesces from self-similar clusters of burst-within-burst behavior during ontogeny, is essential to cognitive-emotional function, and has recurrent fractal organization. Empirical fMRI observations further support the association of fractal fluctuations in the temporal lobes, brainstem and cerebellum during the expression of emotional memory, spontaneous fluctuations of thought and meditative practice. Cognitive-emotional integration arises as amygdaloid-brainstem-cerebellar systems harmonize the vertical “1/f” symphony of coupled isochronous cortical oscillations in the pursuit of mindfulness.
