Translating near-synonyms: Possibilities and preferences in the interlingua

This paper argues that an interlingual representation must explicitly represent some parts of the meaning of a situation as possibilities (or preferences), not as necessary or definite components of meaning (or constraints). Possibilities enable the analysis and generation of nuance, something required for faithful translation. Furthermore, the representation of the meaning of words, especially of near-synonyms, is crucial, because it specifies which nuances words can convey in which contexts.Comment: 8 pages, LaTeX2e, 1 eps figure, uses colacl.sty, epsfig.sty, avm.sty, times.st

Meta-Genetic Programming: Co-evolving the Operators of Variation

The standard Genetic Programming approach is augmented by co-evolving the genetic operators. To do this the operators are coded as trees of indefinite length. In order for this technique to work, the language that the operators are defined in must be such that it preserves the variation in the base population. This technique can varied by adding further populations of operators and changing which populations act as operators for others, including itself, thus to provide a framework for a whole set of augmented GP techniques. The technique is tested on the parity problem. The pros and cons of the technique are discussed

Modelling primary proteolysis in cheddar cheese in commercial cool stores : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Bioprocess Engineering at Massey University

One issue identified as a possible problem during the manufacture of cheddar cheese is the possibility of producing a non-uniform product. It was proposed that a pallet of cheese experiencing different time-temperature histories, depending on the position within the pallet, could cause the heterogeneity. This work involved the investigation of that issue. The level of primary proteolysis observed in cheese was measured over time in cheeses of different compositions, stored at different temperatures. The remaining intact α s ₁casein was measured using reverse phase high performance liquid chromatography. Several trends were observed during maturation. High temperatures caused a faster rate of disappearance of α s ₁casein. The temperature relationship followed Arrhenius law. High moisture content caused a faster rate of the disappearance of α s ₁casein. The level of rennet added to the milk during production had a directly proportional effect on the rate of the disappearance of α s ₁casein. Salt had no observable effect in the range investigated here. From the data a kinetic model was developed that described the rate of disappearance of α s ₁casein in terms of the temperature, the moisture content, and the level of rennet in the cheese. The heat transfer occurring in the commercial pallet of cheese was mathematically modelled and solved numerically. The heat transfer model was then applied to produce data describing the time-temperature profile throughout a pallet of cheese for a variety of possible industrial storage conditions. The kinetic model developed was then used to predict the extent of proteolysis in each case. It was found that there would be significantly different levels of proteolysis within a pallet of cheese that had undergone chilling. A 10% difference in the level of proteolysis between the surface and the centre was observed after chilling for 40 days. During freezing the difference in the level of proteolysis after freezing was complete ranged from 10-25%. It was found that the heterogeneity was reduced during the thawing process and that the greatest reduction in non-uniformity was observed when thawed at lower temperatures

Surgery-for-life:Aging, sexual fitness and self-management in Brazil

This article draws on ethnographic fieldwork on plastic surgery to explore tensions in aging norms and ideals for women in Brazil.  I situate my analysis in relation to debates about a “de-chronologized life course.”  Some scholars argue that the life course in late capitalism has become less standardized.  In this account, chronological age diminishes in importance as consumers are defined by life style choices available to all ages and the period of youth extends into middle age and beyond.  In Brazil consumers embrace plastic surgery as a means to “manage” aging, mental well-being, and reproductive and sexual health.  This promise of a flexible and optimized aging trajectory seems to echo the notion of a de-chronologized life course.  I argue, however, that medical discourse and patients’ accounts show ambivalence about aging and conflicts in the ideal of medically-managed sexual fitness for women.  Drawing on analysis of changes in family structure and women’s health regimes, I argue that passage through the life course, rather than becoming more flexible, is in some ways becoming more rigidly defined by biological processes

The Possible Incommensurability of Utilities and the Learning of Goals

This is a short article to examine the following possibility: that a single agent might simultaneously have different utilities that are incommensurable. Some arguments aginst this possiblity are considered and rejected. Two practical examples are given and its implications in terms of goal change and learning are discussed

Social Embeddedness and Agent Development

Two different reasons for using agents are distinguished: the `engineering' perspective and the `social simulation' perspective. It is argued that this entails some differences in approach. In particular the former will want to prevent unpredictable emergent features of their agent populations whilst the later will want to use simulation to study precisely this phenomena. A concept of `social embeddedness' is explicated which neatly distinguishes the two approaches. It is argued that such embedding in a society is an essential feature of being a truly social agent. This has the consequence that such agents will not sit well within an `engineering' methodology

Beauty and Health: Anthropological Perspectives

This essay, written as a 'teaser' for an up-coming symposium, reflects on how human beauty can be understood from an anthropological and medical anthropological perspective. First, it considers how aesthetic and healing rationales can conflict or merge in a variety of medical technologies and health practices. Second, it discusses beauty in relation to the socioeconomic transformations of modernity and globalization. It suggests the need for a theoretical framework that departs from a strictly constructivist approach and views beauty as a distinct domain of social experience, not reducible to an effect of other inequalities
