The problem of misrepresentation meets connectionist representations : a thesis submitted for the degree of Master of Philosophy

Page 162 is missing from the original copyTheories of semantics try to explain the relationship between a mental representation and the thing it represents; to explain, for instance, how my coffee representation represents coffee. (Here and in the rest of this thesis, I use the convention of writing the label for a representation in bold type.) In many traditional theories of semantics, the relationship between my coffee representation and coffee is usually explained by recourse to causal relations between coffee and this representation. But attempts at explanations along these lines have many problems, among them the problem that it is difficult to find a plausible way of accounting for the fact that representations are able to misrepresent-or have false content. Sometimes I can think "that's coffee" when what's actually in the cup being handed to me is tea. Getting this fact to sit happily with accounts of the relation between my coffee representation and coffee hasn't been an easy task. Traditional approaches to this problem haven't had a lot of success so far in explaining how a representation can misrepresent. In this thesis I aim to avoid the problems with these traditional approaches, and find a causally-based, biologically realistic way to explain semantic relations between mental representations and objects in the world, which is also capable of explaining misrepresentation. The best place to start such an endeavour is to examine what the problem of representation and misrepresentation is, and the general tactics used in traditional attempts to solve this problem. This will illustrate why misrepresentation appears to be so intractable. Through such an examination we can get a close look at the traditional approaches, and their assumptions about what representations are, what sorts of things they represent, and how they can represent what they represent. We can also get a good view of the unquestioned assumptions these traditional theories are based on. This will give us a good place to start. I'm going to argue that if we want to achieve our aim of a biologically realistic theory of semantics which shows how representations can misrepresent, we'll need an approach to the problem which does not take these assumptions as foundations. In this thesis I aim to construct an account which isn't based on these assumptions.[FROM INTRODUCTION

Person to Person in Hong Kong

While still in the midst of their study abroad experiences, students at Linfield College write reflective essays. Their essays address issues of cultural similarity and difference, compare lifestyles, mores, norms, and habits between their host countries and home, and examine changes in perceptions about their host countries and the United States. In this essay, Derek Cash describes his observations during his study abroad program at Hong Kong Baptist University in Hong Kong, China

Transient sensor development

Pulse width/amplitude- and noise-sensors are updated to integrated circuit design concepts, and rise time/amplitude sensor design is reduced to an operational prototype to make all the sensors compatable for one system operation. Therefore, transients interfering with the design operation of receivers could be individually isolated and identified

Attack of the Clones: Legislative Approaches to Human Cloning in the United States

The legal concerns involving the application of cloning technology to humans should be of utmost concern, as the area is extremely complex. Cloning could potentially have great benefits or disastrous effects. Lawmakers have been careful to make certain that the legislation passed is comprehensive and useful for regulation of the ever-changing field of cloning. From debates on whether reproductive or therapeutic cloning should be permitted or banned, to concerns as to who has jurisdiction over cloning, the battle to develop cloning legislation has been difficult. However, this iBrief argues that the currently-proposed federal legislation is constitutional

Hardware problems encountered in solar heating and cooling systems

Numerous problems in the design, production, installation, and operation of solar energy systems are discussed. Described are hardware problems, which range from simple to obscure and complex, and their resolution

Report on the first phase of the study on men’s usage of the Bradford Health of Men services

This is a summary of the full report on the first year of the HOM project in Bradford, published in March 2005 and available at www.healthofmen.com . In this summary there is a concentration on three things, the background to the project, the experiences of the HOM team in setting up and managing projects and the views of the men involved in the projects. The summary is mostly a list of the things that the team found to be important in setting up projects and, equally important, some of the things not to do. There is, of course, a much fuller discussion of the details of projects, supporting data and the theoretical model of how men and health workers interact to manage health

Water Quality Sampling, Analysis and Annual Load Determinations for TSS, Nitrogen and Phosphorus at the Wyman Road Bridge on the White River

A water quality sampling station was installed at the Wyman Road Bridge just below the confluence of the three main forks of the Upper White River in January 2000. This station is coordinated with the USGS gaging station at the same location. This station was instrumented to collect samples at sufficient intervals across the hydrograph to accurately estimate the flux of total suspended solids, nitrogen and phosphorus into the upper end of Beaver Lake from the Upper White River
