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.

In this paper we examine Fehr’s notions of “altruism”, “strong reciprocity” and “altruistic punishment” and query his ascription of altruism. We suggest that, pace Fehr, altruism cannot be defined behaviourally because the definition of altruism must refer to the motives of actors. We also advert to certain inconsistencies in Fehr’s usage of his terms and we question his explanation of altruism in terms of ‘social preferences’.

The shift to a market economy in post-communist Eastern Europe has had a profound impact on science and scientists across the region, leading to reforms in research management practices and to drastic cuts in funding levels everywhere. Many countries are moving to a system of competitive research grants awarded on the basis of peer review. The introduction of peer review is not simply a technical matter. It signifies a fundamental change in the social structure of science, enhancing profession-al autonomy and (...) giving working scientists a voice in the allocation of resources. This book combines first-hand accounts of the reform process with analyses of the strengths and weaknesses of both peer review and quantitative indicators. (shrink)

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)

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.

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)

. Recent corporate scandals have focused the attention of a broad set of constituencies on reforming corporate governance. Boards of directors play a leading role in corporate governance and any significant reforms must encompass their role. To date, most reform proposals have targeted the legal, rather than the ethical obligations of directors. Legal reforms without proper attention to ethical obligations will likely prove ineffectual. The ethical role of directors is critical. Directors have overall responsibility for the ethics and compliance programs (...) of the corporation. The tone at the top that they set by example and action is central to the overall ethical environment of their firms. This role is reinforced by their legal responsibilities to provide oversight of the financial performance of the firm. Underlying this analysis is the critical assumption that ethical behavior, especially on the part of corporate leaders, leads to the best long-term interests of the corporation. We describe key components of a framework for a code of ethics for corporate boards and individual directors. The proposed code framework is based on six universal core ethical values: (1) honesty; (2) integrity; (3) loyalty; (4) responsibility; (5) fairness; and (6) citizenship. The paper concludes by suggesting critical issues that need to be dealt with in firm-based codes of ethics for directors. (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)
