Ruyer and Simondon on Technological Inventiveness and Form Outlasting its Medium
A summary is provided of Ruyer's important contribution, also a reversal from some conclusions held in his secondary doctoral dissertation, about the limits inherent in technological progress, and an attempt is made to show the coherence of this position to Ruyer's metaphysics. Simondon's response is also presented, and subsequently analyzed especially as it culminates in a concept of concretizations. As Simondon indicated, and with a displacement in Ruyer's limitating framework on unconditional growth, we end up searching for what represents the category of the ultimate for those two philosophers of the cyberworld
Cybernetical Concepts for Cellular Automaton and Artificial Neural Network Modelling and Implementation
As a discipline cybernetics has a long and rich history. In its first
generation it not only had a worldwide span, in the area of computer modelling,
for example, its proponents such as John von Neumann, Stanislaw Ulam, Warren
McCulloch and Walter Pitts, also came up with models and methods such as
cellular automata and artificial neural networks, which are still the
foundation of most modern modelling approaches. At the same time, cybernetics
also got the attention of philosophers, such as the Frenchman Gilbert Simondon,
who made use of cybernetical concepts in order to establish a metaphysics and a
natural philosophy of individuation, giving cybernetics thereby a philosophical
interpretation, which he baptised allagmatic. In this paper, we emphasise this
allagmatic theory by showing how Simondon's philosophical concepts can be used
to formulate a generic computer model or metamodel for complex systems
modelling and its implementation in program code, according to generic
programming. We also present how the developed allagmatic metamodel is capable
of building simple cellular automata and artificial neural networks.Comment: 12 pages, 1 figur
Technics, individuation and tertiary memory: Bernard Stiegler's challenge to media theory
Media studies as a field has traditionally been wary of the question of technology. Discussion of technology has often been restricted to relatively sterile debates about technological determinism. In recent times there has been renewed interest, however, in the technological dimension of media. In part this is doubtless due to rapid changes in media technology, such as the rise of the internet and the digital convergence of media technologies. But there are also an increasing number of writers who seem to believe that media theory, and more widely social science and the humanities, needs to rethink the question of technology and its relationship to society, culture and cultural production. Andrew Feenberg has characterized the two most dominant positions as, on the one hand, the social constructivist or 'technology studies' approach to technology, and, on the other, 'substantivist' theories of technology. The social constructivist approach, aims to counter technological determinism by showing how the development of technology is shaped not by technical and scientific progress but by contingent social, cultural and economic forces. The limitation of this view, however, is that it tends to see technology as no different from any other social process and it may lose the ability to distinguish between the technical object and any other social formation or cultural artefact. Doubtless constructivism would like to see technology as a subset of the cultural artefact and not vice versa, therefore explaining technology in terms of culture and society. But there are powerful arguments for arguing something like the opposite: in other words for understanding culture and society in terms of or as technical objects. In recent years this argument has been put most forcefully by the French philosopher Bernard Stiegler and it is to his work and its implications for media theory that this essay is dedicated.
In particular I will show how Stiegler might defend his ideas around technics from the charge of technological determinism. Firstly, technics is not understood in the narrow sense of techno-scientific technology but in the wider sense of all the ways in which the human is exteriorised into artefacts or organized inorganic matter. Technics in this sense is therefore inseparable from culture and society and it makes no sense either to talk of technics determining culture and society or vice versa. Culture and society are not constituted by technics as if by a cause but rather constituted through it. Secondly, a technics in Stiegler's sense does not represent scientific progress or a deterministic evolution; rather, however strange this may seem, technics is a kind of pure accidentality or contingency. For Stiegler it is because of the exteriorisation of the human into artefacts or inorganic organized matter that culture and society constitute themselves contingently. Stiegler's work therefore offers a way for us to rethink the relationship between culture and technology in ways which can productively reconfigure the concerns of critical theory
Feeding practices and growth among young children during two seasons in rural Ethiopia
BACKGROUND: The use of indices of infant and young child feeding practices to predict growth has generated inconsistent results, possibly through age and seasonal confounding. The aim of this study was to evaluate the association of a dietary diversity score (DDS) and infant and child feeding index (ICFI) with growth among young children in a repeated cross-sectional and a follow-up study in two distinct seasons in rural southwest Ethiopia. METHODS: We used a repeated cross-sectional design comparing child feeding practices to nutritional status in 6–12 month old children during harvest (HS; n = 320) and pre-harvest season (PHS; n = 312). In addition, 6–12 month old children from the HS were reassessed 6 months later during PHS. In addition to child anthropometry, child feeding practices were collected using 24-h and 7-day dietary recalls. RESULTS: The mean (±SD) length-for-age z-score (LAZ) of the 6–12 month old children was −0.77 (±1.4) and −1.0 (±1.3) in HS and PHS, respectively, while the mean (±SD) of the follow-up children in PHS was −1.0 (±1.3). The median DDS (IQR) was 2.0 (1.0, 3.0.), 2.0 (2.0, 3.0) and 3.0 (2.0, 4.0) for the children in HS, PHS and the follow-up children in PHS, respectively. The DDS in HS was positively associated with LAZ at follow-up (β = 0.16; 95% CI: 0.01, 0.30; P = 0.03) after controlling for confounding factors. ICFI and DDS were not associated with mean LAZ, weight-for-height z-score and weight-for-age z-score within season. However, the odds of being stunted when having a DDS ≤ 2 was 2.3 times (95% CI: 1.10, 4.78; P = 0.03) higher compared to a DDS > 2 child in HS and 1.7 times (95% CI: 1.04, 2.71; P = 0.04) higher for the pooled sample of 6–12 months old children in HS and PHS. CONCLUSIONS: The DDS was found to be an indicator for child stunting during the Ethiopian harvest season. The DDS can be an appropriate tool to evaluate the association of child feeding practices with child growth irrespective of season. Inclusion of other dimensions in the construction of ICFI should be considered in future analysis as we found no association with growth
