This paper discusses the extent to which books about business ethics are purchased or read outside of tertiary institutions in Australia, whether the subject is commonly perceived as business, philosophy or both, what range of business ethics books is commonly offered for purchase, and what conclusions might be drawn from the above considerations. Investigation shows that the range and availability of business ethics books is quite limited outside of tertiary institutions, and that the general perception is that business ethics is (...) something which pertains specifically to business rather than to moral philosophy. It is likely that this tends to isolate the subject from philosophy as broadly conceived in the minds of business practitioners. (shrink)
In a powerful and original contribution to the history of ideas, Hannah Dawson explores the intense preoccupation with language in early-modern philosophy, and presents a groundbreaking analysis of John Locke's critique of words. By examining a broad sweep of pedagogical and philosophical material from antiquity to the late seventeenth century, Dr Dawson explains why language caused anxiety in writers such as Montaigne, Bacon, Descartes, Hobbes, Gassendi, Nicole, Pufendorf, Boyle, Malebranche and Locke. Locke, Language and Early-Modern Philosophy demonstrates that (...) new developments in philosophy, in conjunction with weaknesses in linguistic theory, resulted in serious concerns about the capacity of words to refer to the world, the stability of meaning, and the duplicitous power of words themselves. Dr Dawson shows that language so fixated all manner of early-modern authors because it was seen as an obstacle to both knowledge and society. She thereby uncovers a novel story about the problem of language in philosophy, and in the process reshapes our understanding of early-modern epistemology, morality and politics. (shrink)
Abstract In this paper, we explore how the application of technological tools has reshaped food production systems in ways that foster large-scale outbreaks of foodborne illness. Outbreaks of foodborne illness have received increasing attention in recent years, resulting in a growing awareness of the negative impacts associated with industrial food production. These trends indicate a need to examine systemic causes of outbreaks and how they are being addressed. In this paper, we analyze outbreaks linked to ground beef and salad greens. (...) These case studies are informed by personal interviews, site visits, and an extensive review of government documents and peer-reviewed literature. To explore these cases, we draw from actor-network theory and political economy to analyze the relationships between technological tools, the design of industrial production systems, and the emergence and spread of pathogenic bacteria. We also examine if current responses to outbreaks represent reflexive change. Lastly, we use the myth of Prometheus to discuss ethical issues regarding the use of technology in food production. Our findings indicate that current tools and systems were designed with a narrow focus on economic efficiency, while overlooking relationships with pathogenic bacteria and negative social impacts. In addition, we find that current responses to outbreaks do not represent reflexive change and a continued reliance on technological fixes to systemic problems may result in greater problems in the future. We argue that much can be learned from the myth of Prometheus. In particular, justice and reverence need to play a more significant role in guiding production decisions.

PDP networks that use nonmonotonic activation functions often produce hidden unit regularities that permit the internal structure of these networks to be interpreted (Berkeley et al., 1995; McCaughan, 1997; Dawson, 1998). In particular, when the responses of hidden units to a set of patterns are graphed using jittered density plots, these plots organize themselves into a set of discrete stripes or bands. In some cases, each band is associated with a local interpretation. On the basis of these observations, Berkeley (...) (2000) has suggested that these bands are both subsymbolic and symbolic in nature, and has used the analysis of one network to support the claim that there are fewer differences between symbols and subsymbols than one might expect. We suggest below that this conclusion is premature. First, in many cases the local interpretation of each band is difficult to relate to the interpretation of a network's response; a more appropriate relationship only emerges when a band associated with one hidden unit is considered in the context of other bands associated with other hidden units (i.e., interpretations of distributed representations are more useful than interpretations of local representations). Second, the content that a band designates to an external observer (i.e., the interpretation assigned to a band by the researcher) can be quite different from the content that a band designates to the output units of the network itself.. We use two different network simulations – including the one described by Berkeley (2000) – to illustrate these points. We conclude that current evidence involving interpretations of nonmonotonic PDP networks actually illustrates the differences between symbolic and subsymbolic processing. (shrink)

This research addresses the question of whether men and women in sales differ in their ethical attitudes and decision making. The study asked 209 subjects to respond to 20 ethical scenarios, half of which were "relational" and half "non-relational." The study concludes (1) that there are significant ethical differences between the sexes in situations that involve relational issues, but not in non-relational situations, and (2) that gender-based ethical differences change with age and years of experience. The implications of these finding (...) for sales organizations are discussed. (shrink)
My aim in this paper is to go some way towards showing that the maintenance of hard and fast dichotomies, like those between mind and body, and the real and the virtual, is untenable, and that technological advance cannot occur with being cognisant of its reciprocal ethical implications. In their place I will present a softer enactivist ontology through which I examine the nature of our engagement with technology in general and with virtual realities in particular. This softer ontology is (...) one to which I will commit Kant, and from which, I will show, certain critical moral and emotional consequences arise. It is my contention that Kant’s logical subject is necessarily embedded in the world and that Kant, himself, would be content with this view as an expression of his inspired response to the “scandal to philosophy… that the existence of things outside us… must be accepted merely on faith” [Bxl]. In keeping with his arguments for the a priori framing of intuition, the a priori structuring of experience through the spontaneous application of the categories, the synthesis of the experiential manifold, and the necessity of a unity of apperception, I will present an enactivist account of agency in the world, and argue that it is our embodied and embedded kinaesthetic engagement in our world which makes possible the syntheses of apprehension, reproduction and recognition, and which, in turn, make possible the activity of the reproductive or creative imagination.

In this paper we consider the concept of a self-aware agent. In cognitive science agents are seen as embodied and interactively situated in worlds. We analyse the meanings attached to these terms in cognitive science and robotics, proposing a set of conditions for situatedness and embodiment, and examine the claim that internal representational schemas are largely unnecessary for intelligent behaviour in animats. We maintain that current situated and embodied animats cannot be ascribed even minimal self-awareness, and offer a six point (...) definition of embeddedness, constituting minimal conditions for the evolution of a sense of self. This leads to further analysis of the nature of embodiment and situatedness, and a consideration of whether virtual animats in virtual worlds could count as situated and embodied. We propose that self-aware agents must possess complex structures of self-directed goals; multi-modal sensory systems and a rich repertoire of interactions with their worlds. Finally, we argue that embedded agents will possess or evolve local co-ordinate systems, or points of view, relative to their current positions in space and time, and have a capacity to develop an egocentric space. None of these capabilities are possible without powerful internal representational capacities. (shrink)
It is argued that, based on Kant's descriptive metaphysics, one can prescribe the necessary metaphysical underpinnings for the possibility of conscious experience in an artificial system. This project is developed by giving an account of the a priori concepts of the understanding in such a system. A specification and implementation of the nomological conditions for a conscious system allows one to know a priori that any system possessing this structure will be conscious; thus enabling us to avoid possible false-indicators of (...) consciousness like that offered in a behaviouristic analysis. This is an alternative approach to the bottom-up or top-down approaches adopted by, for example CYC (Lenat and Feigenbaum 1992) and COG (Brooks 1994; Brooks and Stein 1993), neither of which, alone, or in some hybrid form, have proved productive.

This paper examines what social auditing has to offer Oxfam and similar organisations involved in the collection of charitable donations for international development and relief operations in terms of improving the quality of their work, increasing their accountability to stakeholders, and their capacity to achieve impact in terms of their institutional goals. In looking at the particular case of Oxfam, it discusses issues in relation to the establishment of social auditing with relevance for similar organisations.The paper points out that since (...) Oxfam is not a profit-making organisation, but one based on a humanitarian impulse, there are many ways in which it already lives up to the ideals of social audit. The paper lists areas of governance and systems where Oxfam is currently responding to the major principles of social audit, and some of the issues encountered in doing so. These principles have been defined by Zadek (1997) as follows. (shrink)
Machine consciousness exists already in organic systems and it is only a matter of time -- and some agreement -- before it will be realised in reverse-engineered organic systems and forward- engineered inorganic systems. The agreement must be over the preconditions that must first be met if the enterprise is to be successful, and it is these preconditions, for instance, being a socially-embedded, structurally-coupled and dynamic, goal-directed entity that organises its perceptual input and enacts its world through the application of (...) both a cognitive and kinaesthetic imagination, that I shall concentrate on presenting in this paper. It will become clear that these preconditions will present engineers with a tall order, but not, I will argue, an impossible one. After all, we might agree with Freeman and Núñez's claim that the machine metaphor has restricted the expectations of the cognitive sciences (Freeman & Núñez, 1999); but it is a double-edged sword, since our limited expectations about machines also narrow the potential of our cognitive science.

The crux of this book is expressed in one short sentence from the Preface: 'Unity is a fundamental part of our experience, something that is crucial to its phenomenology' [p.xii], and the crux of this sentence is that the unity of consciousness is not a matter of phenomenal relations existing between distinct experiences – the received view [p.17], but the existence of relations between the contents of experiences – the one experience view [p.25ff]. In its simplest form Tye's claim is (...) that: all our conscious states, whether visual, auditory, olfactory, tactual or gustatory, whether imagistic or emotional are experienced concurrently; they 'are phenomenologically unified ... [and] ... Phenomenological unity is a relation between qualities represented in experience, not between qualities of experiences. [p.36]. (shrink)
The aim of this paper is to establish the logically necessary preconditions for the existence of self-awareness in an artificial or a natural agent. We examine the terms, agent, situated, embodied, embedded, and representation, as employed ubiquitously in cognitive science, attempting to clarify their meaning and the limits of their use. We discuss the minimal conditions for an agent’s environment constituting a ‘world’ and reject most, though not all, types of virtual world. We argue that to qualify as genuinely situated (...) an agent should function in real time within the dynamic world we inhabit, or some close simulacrum of it. We show that embodied agents will possess or evolve local co-ordinate systems, or points of view, locating, identifying and interacting with objects relative to their current position in space-time, and we discuss various types of embodiment, arguing that most current situated and embodied systems are too limited to be candidates for even the most minimal claim to self-identity. We argue that a truly autonomous agent has to be active in its participation with the world, able to synthesise and order its internal representations from its own point of view, and to do this effectively the agent will have to be embedded. To this end we propose a six point definition of embeddedness. Ultimately we argue for a philosophical-cum-cognitive science model of the self that satisfies essential elements of both sets of definitions of the term. (shrink)
While the recent special issue of JCS on machine consciousness (Volume 14, Issue 7) was in preparation, a collection of papers on the same topic, entitled Artificial Consciousness and edited by Antonio Chella and Riccardo Manzotti, was published. The editors of the JCS special issue, Ron Chrisley, Robert Clowes and Steve Torrance, thought it would be a timely and productive move to have authors of papers in their collection review the papers in the Chella and Manzotti book, and include these (...) reviews in the special issue of the journal. Eight of the JCS authors (plus Uziel Awret) volunteered to review one or more of the fifteen papers in Artificial Consciousness; these individual reviews were then collected together with a minimal amount of editing to produce a seamless chapter-by-chapter review of the entire book. Because the number and length of contributions to the JCS issue was greater than expected, the collective review of Artificial Consciousness had to be omitted, but here at last it is. Each paper's review is written by a single author, so any comments made may not reflect the opinions of all nine of the joint authors! (shrink)
We assert that one of the examples used by Keller & Miller (K&M), namely, autism, is indeed common, and heritable, but we question whether it is harmful. We provide a brief review of cognitive science literature in which autistics perform superiorly to non-autistics in perceptual, reasoning, and comprehension tasks; however, these superiorities are often occluded and are instead described as dysfunctions.

There is widespread belief that connectionist networks are dramatically different from classical or symbolic models. However, connectionists rarely test this belief by interpreting the internal structure of their nets. A new approach to interpreting networks was recently introduced by Berkeley et al. (1995). The current paper examines two implications of applying this method: (1) that the internal structure of a connectionist network can have a very classical appearance, and (2) that this interpretation can provide a cognitive theory that cannot be (...) dismissed as a mere implementation.

Pylyshyn argues that many of the methods used to study perception are too coarse to detect the distinction between perceptual and cognitive processing. We suggest that the reason for this is that the theories used to guide research in perception are at fault. More powerful theories – for instance, computer simulations – will be required to identify where perception ends and where cognition begins.
It has been acknowledged on numerous occasions that personal religiousness is a potential source of ethical norms, and consequently, an influence in ethical evaluations. An extensive literature review provides little in the way of empirical investigation of this recognized affect. This investigation conceptualizes religiousness as a motivation for ethical action, and discovers significant differences in ethical judgements among respondents categorized by personal religious motivation. Suggestions as to the source of these differences, and the implications which they offer to managers are (...) discussed and supported from the literature. (shrink)
One new tradition that has emerged from early research on autonomous robots is embodied cognitive science. This paper describes the relationship between embodied cognitive science and a related tradition, synthetic psychology. It is argued that while both are synthetic, embodied cognitive science is antirepresentational while synthetic psychology still appeals to representations. It is further argued that modern connectionism offers a medium for conducting synthetic psychology, provided that researchers analyze the internal representations that their networks develop. The paper then provides a (...) detailed example of the synthetic approach by showing how the construction (and subsequent analysis) of a connectionist network can be used to contribute to a theory of how humans solve Piaget's classic balance scale task.

In this paper, I develop some internal problems with Alvin Plantanga's proper functionalist epistemology. I focus on: (1) how we know that a belief is the result of proper function and the special difficulties this occasions for religious beliefs; (2) what a properly functioning person should believe in various circumstances, and (3) the problem of design -- whether the claim that God designed us can be reconciled with the claim that He was subject to trade-offs, compromises and unintended by-products. These (...) serious internal problems cast doubt upon proper functionalism's fruitfulness as a theory of knowledge. (shrink)

In the end that material, as well as some other manuscript items from Gödel's "Nachlass," had to be left out.

Some examples of sources outside Gödel's "Nachlass" that may be of interest to Gödel scholars (...) are also indicated. (shrink)
This article addresses the two main obstacles — ignorance and conflict — that block the pathway to ethically proper conduct, both generally in business and specifically in marketing. It begins with a brief examination of theories of the moral good which emphasizes the Greco-Roman humanistic tradition and the Judeo-Christian religious tradition. A professional code of ethics, such as the code of the American Marketing Association, is meaningful only if human beings are regarded as making moral judgments that, objectively speaking, are (...) morally wrong, that is only when the code is considered a set of moral absolutes.Following that, the question of ignorance is dealt with utilizing the American Marketing Association code of ethics. The specific items in that code are related to the three central principles of economic justice: equivalence, contributive justice, and distributive justice. In the second section, the question of conflict is encountered in the context of four other ethical principles — double effect, culpability, good end and bad means, self-determination — that are likely to be helpful in dealing with two cases that are especially instructive because they are limiting cases: the dilemma and the hard case. The role of the hero or champion in conflicts is underscored. (shrink)
Narrative is increasingly being recognised as an important tool both to manage and understand organisations. In particular, narrative is recognised to have an important influence on the perception of environmental issues in business, a particularly contested area of modern management. Management literature is, however, only beginning to develop a framework for evaluating the quality and legitimacy of narratives. Due to the highly fluid nature of narratives, the traditional notion of truth as reflecting ' objective reality' is not useful here. In (...) this article, an alternative approach that evaluates a narrative in two stages is developed. First, a horizontal reading investigates the surface of the narrative, its textual features, instrumental devices and its integrity as a text, to assess the quality of a narrative. Second, a more philosophical or vertical reading makes explicit the underlying value assumptions that author and reader bring to the writing and reading of the narrative to assess the narrative's claim to legitimacy. The framework is then tested against a narrative on the relationship between business and environment as espoused by a supply chain manager of a UK-based manufacturing company. (shrink)
. The use of narrative to communicate and convey particular points of view in society has increasingly become the focus of academic attention in recent years. In particular, MacIntyre. (1985, 1988, 1990, 1999) has paid attention to the role of narrative in the conflict between different traditions when developing his virtue approach to ethics. Whilst there has been continued debate about the application of virtue approaches, some arguing that it is incompatible with business, I disagree and have already argued for (...) a form of virtue that will focus business on society’s needs rather than better business itself. Here I continue to develop the argument in two ways. First, I will explore the predominant business narrative and offer some comment on the ‘virtues’ that it promotes. However, rather than accepting this narrative, I want to challenge it with a narrative from the environmental tradition. I consider how adopting the virtues promoted by an environmental narrative it would shape business practices and challenge current business conventions. As a second step, I will focus on how we can change managers’ perceptions of business to reflect these environmentally based virtues. (shrink)
The management literature is replete with studies on business ethics. Unfortunately, most of these studies have dealt exclusively with ethics in large businesses. Although a handful of studies can be found on small business ethics, none has paid attention to the issue of ethics in small minority businesses. Similarly, several studies on ethics have utilized the Wood et al. (1988) 16-vignette ethics scale, although reliability and validity issues associated with the scale have never been fully addressed. In this study, a (...) purification (via content analysis) of the above mentioned scale was performed. Three reliable factors were extracted from the purified scale. They were used to investigate the ethics in small minority businesses. The study found an association between business ethics and demographic and company-related variables. In the case of age of respondents, findings ran counter the usual relationship of age being positively related to ethical attitudes. The implications of these findings are also discussed. (shrink)
In 1998, the US Supreme Court first held that asymptomatic HIV infection constituted a disability when it ruled on the case of Bragdon v. Abbott . The use of yet another label (disabled) to identify women living with HIV has been rarely (if ever) questioned. While we do value the use of this label as an anti-discriminatory strategy, we believe that there is a need to examine how language and more specifically, the use of words such as disability, (...) limitation, and impairment may create new forms of identities for women living with HIV. Using this legal case as a starting point, the goal of this paper is to critically examine the 'fabrication' of asymptomatic HIV infection as a disability. Grounded in a feminist poststructuralist perspective, this paper exposes the relationship between language, social institutions, subjectivity, and power in the construction of difference. By doing so, it addresses the identification of women living with HIV/AIDS as disabled and the self-differentiation process that they must go through in order to live as normally as possible.

A number of studies in the apparent motion literature were examined using the cognitive penetrability criterion to determine the extent to which beliefs affect the perception of apparent motion. It was found that the interaction between the perceptual processes mediating apparent motion and higher order processes appears to be limited. In addition, perceptual and inferential beliefs appear to have different effects on perceived motion optimality and direction. Our findings suggest that the system underlying apparent motion perception has more than one (...) stage and is informationally encapsulated from cognitive factors. (shrink)
We re-express our theorem on the strong-normalisation of display calculi as a theorem about the well-foundedness of a certain ordering on first-order terms, thereby allowing us to prove the termination of systems of rewrite rules. We first show how to use our theorem to prove the well-foundedness of the lexicographic ordering, the multiset ordering and the recursive path ordering. Next, we give examples of systems of rewrite rules which cannot be handled by these methods but which can be handled by (...) ours. Finally, we show that our method can also prove the termination of the Knuth-Bendix ordering and of dependency pairs. Keywords: rewriting, termination, well-founded ordering, recursive path ordering.. (shrink)
This paper critically examines the claim that parallel distributed processing (PDP) networks are autonomous learning systems. A PDP model of a simple distributed associative memory is considered. It is shown that the 'generic' PDP architecture cannot implement the computations required by this memory system without the aid of external control. In other words, the model is not autonomous. Two specific problems are highlighted: (i) simultaneous learning and recall are not permitted to occur as would be required of an autonomous system; (...) (ii) connections between processing units cannot simultaneously represent current and previous network activation as would be required if learning is to occur. Similar problems exist for more sophisticated networks constructed from the generic PDP architecture. We argue that this is because these models are not adequately constrained by the properties of the functional architecture assumed by PDP modelers. It is also argued that without such constraints, PDP researchers cannot claim to have developed an architecture radically different from that proposed by the Classical approach in cognitive science.

Anthropologists now openly acknowledge that social anthropology can no longer fulfill its traditional aim of providing holistic, objective representations of people of "exotic" cultures. After Writing Culture asks what theoretical and practical role contemporary anthropology can play in our increasingly unpredictable and complex world. With fourteen articles written by well-known anthropologists, the work explores some of the directions in which contemporary anthropology is moving, following the questions raised by the "writing culture" debates of the 1980s. Some of the chapters cover: (...) the concept of caste in Indian society, Scottish ethnography, how dreams are culturally conceptualized, representations of the family, theme parks and the anthropologist in Japan, people's place in the landscape of Northern Australia, and representing the identity of the New Zealand Maori.

We compare several methods of implementing the display (sequent) calculus RA for relation algebra in the logical frameworks Isabelle and Twelf. We aim for an implementation enabling us to formalise within the logical framework proof-theoretic results such as the cut-elimination theorem for RA and any associated increase in proof length. We discuss issues arising from this requirement.
Schyns et al.'s (1998) target article raises a conflict between the need for a fixed functional architecture in an explanatory cognitive science and the need for a system to learn to detect new features. This conflict can be resolved by avoiding the scope slip in which properties of objects are erroneously viewed as being properties of their representations.
This paper examines whether a classical model could be translated into a PDP network using a standard connectionist training technique called extra output learning. In Study 1, standard machine learning techniques were used to create a decision tree that could be used to classify 8124 different mushrooms as being edible or poisonous on the basis of 21 different Features (Schlimmer, 1987). In Study 2, extra output learning was used to insert this decision tree into a PDP network being trained on (...) the identical problem. An interpretation of the trained network revealed a perfect mapping from its internal structure to the decision tree, representing a precise translation of the classical theory to the connectionist model. In Study 3, a second network was trained on the mushroom problem without using extra output learning. An interpretation of this second network revealed a different algorithm for solving the mushroom problem, demonstrating that the Study 2 network was indeed a proper theory translation. (shrink)

Representation of similarities is not sufficient for most visual tasks. The proposed framework collapses useful dimensions such as position and pose for the sake of naming the object. Collapsing these dimensions leaves no representation of the object itself, but only an internal name that cannot be meaningfully manipulated.
