Horizontal Models of Conviviality or Radical Democracy in the Americas: Zapatistas, Boggs Center, Casa Pueblo

In this paper, I argue that despite their different circumstances (size, location, history, demography), the Zapatistas (Chiapas, Mexico), Boggs Center (Detroit, USA), and Casa Pueblo (Adjuntas, Puerto Rico) share common lessons that are worth considering, at a time when there is so much uncertainty and disagreement about how best to address social injustices and much disillusionment with representative democracy. After a summary of the history and accomplishments of each of these American communal activist organisations, I present the common lessons and consider some challenges and possible objections. They provide an alternative between naïve optimism and cynical passive pessimism. They practice horizontal models of conviviality and a holistic, ecological, and experimental approach to ameliorating injustices

El punto de partida de la filosofía en Risieri Frondizi y el pragmatismo

The work of Risieri Frondizi (1910-1983) is an important historical and philosophical connection between the Hispanic world and American philosophy. Frondizi shares with the classical American pragmatists, especially with John Dewey, (1) the same criticism of the starting point of modern philosophy, and (2) a defense of ‘experience’ as the proper basis for any philosophical inquiry. Moreover, (3) Frondizi can be read as making significant and original contributions to the history of doctrines such as pragmatism, which take ‘experience’ as their starting point

QUANTITATIVE METHOD FOR DETERMINING A REPRESENTATIVE ALGAL SAMPLE COUNT 1

A method for determining a representative count of a sample dependent on number of species is presented for application to various algal communities. Constant species curves are calculated as efficiency = (number of individuals–number of species)/number of individuals and diagrammed on a plot of efficiency versus number of individuals counted. Efficiency is defined as the probability that a new species encountered is minimal. That is, as the ratio of number of species to number of individuals approaches 1, more individuals will need to be counted in order to achieve a representative count. Data and calculations of efficiency from two algal communities are presented for illustration.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66065/1/j.0022-3646.1996.00693.x.pd

Quantitative morphometric methods in diatom research

Morphometric methods have been used in diatom research for decades. We present a review of the history of usage of morphometric methods of outline shape analysis, pattern recognition, and landmarkbased analysis. In addition, we present how morphometric methods are important in diatom taxonomy and classifi cation and what connections exist between morphometric methods and biologically meaningful results. Next, we present some details about calculating shape descriptors and using them in analysis of shape variation, the issues to be aware of, and what such results mean when defi ning shape groups as species groups. Finally, we provide a glimpse of the future in using morphometric methods in diatom research.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/117649/1/bibl_diatom_62_strelnikova.pdfDescription of bibl_diatom_62_strelnikova.pdf : Main articl

Processing and Linking Audio Events in Large Multimedia Archives: The EU inEvent Project

In the inEvent EU project [1], we aim at structuring, retrieving, and sharing large archives of networked, and dynamically changing, multimedia recordings, mainly consisting of meetings, videoconferences, and lectures. More specifically, we are developing an integrated system that performs audiovisual processing of multimedia recordings, and labels them in terms of interconnected “hyper-events ” (a notion inspired from hyper-texts). Each hyper-event is composed of simpler facets, including audio-video recordings and metadata, which are then easier to search, retrieve and share. In the present paper, we mainly cover the audio processing aspects of the system, including speech recognition, speaker diarization and linking (across recordings), the use of these features for hyper-event indexing and recommendation, and the search portal. We present initial results for feature extraction from lecture recordings using the TED talks. Index Terms: Networked multimedia events; audio processing: speech recognition; speaker diarization and linking; multimedia indexing and searching; hyper-events. 1

Electric-field noise from carbon-adatom diffusion on a Au(110) surface: first-principles calculations and experiments

The decoherence of trapped-ion quantum gates due to heating of their motional modes is a fundamental science and engineering problem. This heating is attributed to electric-field noise arising from the trap-electrode surfaces. In this work, we investigate the source of this noise by focusing on the diffusion of carbon-containing adsorbates on the surface of Au(110). We show by density functional theory, based on detailed scanning probe microscopy, how the carbon adatom diffusion on the gold surface changes the energy landscape, and how the adatom dipole moment varies with the diffusive motion. A simple model for the diffusion noise, which varies quadratically with the variation of the dipole moment, qualitatively reproduces the measured noise spectrum, and the estimate of the noise spectral density is in accord with measured values.Comment: 8 pages, 6 figure
