Rumelhart and McClelland's chapter about learning the past tense created a degree of controversy extraordinary even in the adversarial culture of modern science. It also stimulated a vast amount of research that advanced the understanding of the past tense, inflectional morphology in English and other languages, the nature of linguistic representations, relations between language and other phenomena such as reading and object recognition, the properties of artificial neural networks, and other topics. We examine the impact of the Rumelhart and McClelland (...) model with the benefit of 25 years of hindsight. It is not clear who “won” the debate. It is clear, however, that the core ideas that the model instantiated have been assimilated into many areas in the study of language, changing the focus of research from abstract characterizations of linguistic competence to an emphasis on the role of the statistical structure of language in acquisition and processing.

Languages and writing systems result from satisfying multiple constraints related to learning, comprehension, production, and their biological bases. Orthographies are not optimal because these constraints often conflict, with further deviations due to accidents of history and geography. Things tend to even out because writing systems and the languages they represent exhibit systematic trade-offs between orthographic depth and morphological complexity.

Inflectional morphology has been taken as a paradigmatic example of rule-governed grammatical knowledge (Pinker, 1999). The plausibility of this claim may be related to the fact that it is mainly based on studies of English, which has a very simple inflectional system. We examined the representation of inflectional morphology in Serbian, which encodes number, gender, and case for nouns. Linguists standardly characterize this system as a complex set of rules, with disagreements about their exact form. We present analyses of a (...) large corpus of nouns which showed that, as in English, Serbian inflectional morphology is quasiregular: It exhibits numerous partial regularities creating neighborhoods that vary in size and consistency. We then asked whether a simple connectionist network could encode this statistical information in a manner that also supported generalization. A network trained on 3,244 Serbian nouns learned to produce correctly inflected phonological forms from a specification of a word's lemma, gender, number, and case, and generalized to untrained cases. The model's performance was sensitive to variables that also influence human performance, including surface and lemma frequency. It was also influenced by inflectional neighborhood size, a novel measure of the consistency of meaning to form mapping. A word-naming experiment with native Serbian speakers showed that this measure also affects human performance. The results suggest that, as in English, generating correctly inflected forms involves satisfying a small number of simultaneous probabilistic constraints relating form and meaning. Thus, common computational mechanisms may govern the representation and use of inflectional information across typologically diverse languages. (shrink)

We distinguish between literal and metaphorical applications of Bayesian models. When intended literally, an isomorphism exists between the elements of representation assumed by the rational analysis and the mechanism that implements the computation. Thus, observation of the implementation can externally validate assumptions underlying the rational analysis. In other applications, no such isomorphism exists, so it is not clear how the assumptions that allow a Bayesian model to fit data can be independently validated.

Ethical decision-making descriptive theoretical models often conflict with each other and typically lack comprehensiveness. To address this deficiency, a revised EDM model is proposed that consolidates and attempts to bridge together the varying and sometimes directly conflicting propositions and perspectives that have been advanced. To do so, the paper is organized as follows. First, a review of the various theoretical models of EDM is provided. These models can generally be divided into rationalist-based ; and non-rationalist-based. Second, the proposed model, called (...) ‘Integrated Ethical Decision Making,’ is introduced in order to fill the gaps and bridge the current divide in EDM theory. The individual and situational factors as well as the process of the proposed model are then described. Third, the academic and managerial implications of the proposed model are discussed. Finally, the limitations of the proposed model are presented. (shrink)

Abstract:Extrapolating from Carroll’s four domains of corporate social responsibility (1979) and Pyramid of CSR (1991), an alternative approach to conceptualizing corporate social responsibility (CSR) is proposed. A three-domain approach is presented in which the three core domains of economic, legal, and ethical responsibilities are depicted in a Venn model framework. The Venn framework yields seven CSR categories resulting from the overlap of the three core domains. Corporate examples are suggested and classified according to the new model, followed by a discussion (...) of limitations and teaching and research implications. (shrink)

The study examines employee, managerial, and ethics officer perceptions regarding their companies codes of ethics. The study moves beyond examining the mere existence of a code of ethics to consider the role that code content and code process (i.e. creation, implementation, and administration) might play with respect to the effectiveness of codes in influencing behavior. Fifty-seven in-depth, semi-structured interviews of employees, managers, and ethics officers were conducted at four large Canadian companies. The factors viewed by respondents to be important with (...) respect to code effectiveness include: provisions of examples; readability; tone; relevance; realism; senior management support; training; reinforcement; living up to standards; reporting requirement; anonymous phone line; communicating violations; and enforcement. The factors found to be potentially important include: justification for provisions; employee involvement; and sign-off requirements. Factors found not to be important include: objectives for the code; prior distribution; testing; and relating ones performance review to compliance with the code. (shrink)

Can or should God be considered a managerial stakeholder? While at first glance such a proposition might seem beyond the norms of stakeholder management theory or traditional management practice, further investigation suggests that there might be both theoretical and practical support for such a notion. This paper will make the argument that God both is and should be considered a managerial stakeholder for those businesspeople and business firms that accept that God exists and can affect the world. In doing so, (...) part one of the paper first discusses the growth of religion and spirituality within the business and academic communities. Part two raises several arguments based on stakeholder theory and business reality to support the notion of God as a managerial stakeholder. Part three addresses the arguments against God as a managerial stakeholder. Part four discusses the managerial implications of considering God as a managerial stakeholder. The paper concludes with its limitations. (shrink)

There appears to be an implicit assumption by those connected with the ethical investment movement (e.g., ethical investment firms, individual investors, social investment organizations, academia, and the media), that ethical investment is in fact ethical. This paper will attempt to challenge the notion that the ethical mutual fund industry, as currently taking place, is acting in an ethical manner. Ethical issues such as the transparency of the funds and advertising are discussed. Ethical mutual fund screens such as tobacco, alcohol, gambling, (...) and the military are preliminarily examined to better determine whether they can actually be defined as "ethical" screens as opposed to merely social, political, or religious screens. A code of ethics for ethical investment is constructed by which ethical mutual fund firms can be audited for ethical compliance. (shrink)

This paper attempts to build on the contribution to moral imagination theory by Patricia Werhane by further integrating moral imagination with new theoretical developments that have taken place in the business ethics field. To accomplish this objective, part one will review the concept of moral imagination, from its definitional origins to its full theoretical conceptualization. Part two will provide a brief literature review of how moral imagination has been applied in empirical research. Part three will analyze and apply the construct (...) of moral imagination as it relates to the key process stages of ethical decision making including awareness, judgment, intention, and behavior. Immoral imagination is then discussed, along with other behavioral ethics concepts as they relate to moral imagination. The paper concludes with potential future research directions, as well as teaching and managerial implications for the moral imagination construct. (shrink)

Are corporate codes of ethics necessarily ethical? To challenge this notion, an initial set of universal moral standards is proposed by which all corporate codes of ethics can be ethically evaluated. The set of universal moral standards includes: (1) trustworthiness; (2) respect; (3) responsibility; (4) fairness; (5) caring; and (6) citizenship. By applying the six moral standards to four different stages of code development (i.e., content, creation, implementation, administration), a code of ethics for corporate codes of ethics is constructed by (...) which companies can be ethically audited for compliance. The newly proposed code of ethics for corporate codes of ethics was then applied to four large Canadian companies representing a variety of industries: telecommunications; banking, manufacturing, and high technology. The ethical audit of the four companies' ethics programs based on the proposed code indicates that all four companies have room to improve the ethical nature of their codes of ethics (i.e., content, creation, implementation, administration).

How can one establish if a corporate code of ethics is ethical in terms of its content? One important first step might be the establishment of core universal moral values by which corporate codes of ethics can be ethically constructed and evaluated. Following a review of normative research on corporate codes of ethics, a set of universal moral values is generated by considering three sources: (1) corporate codes of ethics; (2) global codes of ethics; and (3) the business ethics literature. (...) Based on the convergence of the three sources of standards, six universal moral values for corporate codes of ethics are proposed including: (1) trustworthiness; (2) respect; (3) responsibility; (4) fairness; (5) caring; and (6) citizenship. Relying on the proposed set of universal moral values, implications are discussed as to what the content of corporate codes of ethics should consist of. The paper concludes with its limitations.
