We use the Newell Test as a basis for evaluating ACT-R as an effective architecture for cognitive engineering. Of the 12 functional criteria discussed by Anderson & Lebiere (A&L), we discuss the strengths and weaknesses of ACT-R on the six that we postulate are the most relevant to cognitive engineering.

Reinforcement learning (RL) models of decision-making cannot account for human decisions in the absence of prior reward or punishment. We propose a mechanism for choosing among available options based on goal-option association strengths, where association strengths between objects represent previously experienced object proximity. The proposed mechanism, Goal-Proximity Decision-making (GPD), is implemented within the ACT-R cognitive framework. GPD is found to be more efficient than RL in three maze-navigation simulations. GPD advantages over RL seem to grow as task difficulty is increased. (...) An experiment is presented where participants are asked to make choices in the absence of prior reward. GPD captures human performance in this experiment better than RL. (shrink)

Inspired by a 1988 trip to El Salvador, Michael J. Perry's new book is a personal and scholarly exploration of the idea of human rights. Perry is one of our nation's leading authorities on the relation of morality, including religious morality, to politics and law. He seeks, in this book, to disentangle the complex idea of human rights by way of four probing and interrelated essays. * The initial essay, which is animated by Perry's skepticism about the capacity of (...) any secular morality to offer a coherent account of the idea of human rights, suggests that the first part of the idea of human rights--the premise that every human being is "sacred" or "inviolable"--is inescapably religious. * Responding to recent criticism of "rights talk", Perry explicates, in his second essay, the meaning and value of talk about human rights. * In his third essay, Perry asks a fundamental question about human rights: Are they universal? In addressing this question, he disaggregates and criticizes several different varieties of "moral relativism" and then considers the implications of these different relativist positions for claims about human rights. * Perry turns to another fundamental question about human rights in his final essay: Are they absolute? He concludes that even if no human rights, understood as moral rights, are absolute or unconditional, some human rights, understood as international legal rights, are--and indeed, should be--absolute. In the introduction, Perry writes: "Of all the influential--indeed, formative--moral ideas to take center stage in the twentieth century, like democracy and socialism, the idea of human rights is, for many, the most difficult. It is the most difficult in the sense that it is, for many, the hardest of the great moral ideas to integrate, the hardest to square, with the reigning intellectual assumptions of the age, especially what Bernard Williams has called 'Nietzsche's thought': 'There is not only no God, but no metaphysical order of any kind....' For those who accept 'Nietzsche's thought', can the idea of human rights possibly be more than a kind of aesthetic preference? In a culture in which it was widely believed that there is no God or metaphysical order of any kind, on what basis, if any, could the idea of human rights long survive?" The Idea of Human Rights: Four Inquiries will appeal to students of many disciplines, including law, philosophy, religion, and politics. (shrink)

Legal scholarship exploring the nature of evidence and the process of juridical proof has had a complex relationship with formal modeling. As evident in so many fields of knowledge, algorithmic approaches to evidence have the theoretical potential to increase the accuracy of fact finding, a tremendously important goal of the legal system. The hope that knowledge could be formalized within the evidentiary realm generated a spate of articles attempting to put probability theory to this purpose. This literature was both insightful (...) and frustrating. Much light was shed on the legal system, but it also quickly became evident that the tools of probability theory were in many ways ill-constructed for the task. Fundamental incompatibilities between the structure of legal decision making and the extant formal tools were identified, and it became evident that many of the purported explanations of legal phenomena were internally inconsistent. As a consequence, interest in this type of formal modeling declined, and attention was directed toward different kinds of explanations of the phenomena. Perhaps under the influence of a recent trend toward various types of formal modeling in legal scholarship, a recent burst of articles, rather than attempting to explain the macro structure of trials, which was the previous object of interest, attempts to quantify the probative value of various items of evidence in ways consistent with the formal features of various probability theories, and then to study decision making from that perspective. For example, the value of evidence is often purported to be its likelihood ratio, that is, the probability of discovering or receiving the evidence given a hypothesis (e.g., the defendant did it) divided by the probability of discovering or receiving the evidence given the negation of the hypothesis (the defendant didn't do it). Alternatively, the value of evidence is purported (more contextually) to be the information gain it provides, defined as the increase in probability it provides for a hypothesis above the probability of the hypothesis based on the other available evidence. Both conceptions then assume that all of the various probability assessments conform or ought to conform to the dictates of Bayes' theorem (that maintains consistency among such assessments); empirical studies are then done testing the extent to which this is so and proposing how the law can increase the probability that it is so. The general criticisms of using Bayes' theorem as a formal model of juridical proof are well known and were integral to the last wave of interest in formal modeling of the evidentiary process. This paper thus for the most part puts aside that more general issue, and focuses specifically on mathematical modeling of the value of particular items of evidence. The paper demonstrates that formal modeling has only limited value in explaining the value of legal evidence, much more limited than those constructing and discussing the models assume, and thus that the conclusions they draw about the value of evidence are unwarranted. This is done through a discussion of four recent examples that attempt to quantify evidence relating to, respectively, carpet fibers, infidelity, DNA random-match evidence, and character evidence used to impeach a witness. This article thus makes two contributions. First, and most importantly, it is another demonstration of the complex relationship between algorithmic tools and legal decision making. Second, at a minimum it points out serious pitfalls for analytical or empirical studies of juridical proof. (shrink)

The workshop “Machine Learning: Prediction Without Explanation?” brought together philosophers of science and scholars from various fields who study and employ Machine Learning (ML) techniques, in order to discuss the changing face of science in the light of ML's constantly growing use. One major focus of the workshop was on the impact of ML on the concept and value of scientific explanation. One may speculate whether ML’s increased use in science exemplifies a paradigmatic turn towards mere pattern recognition and prediction (...) and away from science’s traditional aim of explanation. In contrast, certain conceptions of explanation, such as statistical explanation, could turn out to fit well with the achievements of present-day ML and concede an explanatory value to these achievements after all. It is an open question how to explain ML successes themselves, and this question was in the focus of several talks in the workshop. Based on the topics raised, we will discuss the talks’ contents in more detail as organized into (i) practitioners’ perspectives, (ii) explanations from ML, (iii) explanations of ML, (iv) societal implications, and (v) global and historical perspectives.

From Greek antiquity to the latest theories, this historical survey of political philosophy not only covers the major thinkers in the field but also explores the theme of how political philosophy relates to the nature of man. It illustrates how the great political thinkers have always grounded their political thought in what the author terms a "normative anthropology," which typically has not only ethical but metaphysical and/or theological components. Starting with the ancient Greek Sophists, author Michael J. White examines (...) how thinkers over the centuries have approached such political and philosophical concerns as justice, morality, and human flourishing, offering substantial studies of--among others--Plato, Aristotle, Cicero, Locke, Hobbes, Rousseau, Marx, and J. S. Mill. White highlights the impact of Christianity on political philosophy, illustrating the diversity of that impact by studies of Augustine, Aquinas, and Marsilius of Padua. Concluding with an in-depth analysis of John Rawls and contemporary liberal political philosophy, this text blends insight and information in a refreshing and useful manner. A brief Epilogue considers both the value and the limitations of political philosophy and its study. (shrink)

This book offers a broad-based study of Jonathan Edwards as a religious thinker. Much attention has been given to Edwards in relation to his Puritan and Calvinist forebears. McClymond, however, examines Edwards in relation to his eighteenth-century intellectual context. In each of six chapters, he contextualizes and interprets some text or issue in Edwards within the emergent post-Lockean, post-Newtonian culture of the English-speaking world of the 1700s. Among the topics considered are spiritual perception, metaphysics, contemplation, ethics and morality, and apologetics.

The food industry faces many significant risks from public criticism of corporate social responsibility (CSR) issues in the supply chain. This paper draws upon previous research and emerging industry trends to develop a comprehensive framework of supply chain CSR in the industry. The framework details unique CSR applications in the food supply chain including animal welfare, biotechnology, environment, fair trade, health and safety, and labor and human rights. General supply chain CSR issues such as community and procurement are also considered. (...) Ultimately, the framework serves as a comprehensive tool to support food industry practitioners and researchers in the assessment of strategic and operational supply chain CSR practices. (shrink)

We discuss a research project that develops and applies algorithms for computational contextual vocabulary acquisition (CVA): learning the meaning of unknown words from context. We try to unify a disparate literature on the topic of CVA from psychology, first- and secondlanguage acquisition, and reading science, in order to help develop these algorithms: We use the knowledge gained from the computational CVA system to build an educational curriculum for enhancing students’ abilities to use CVA strategies in their reading of science texts (...) at the middle-school and college undergraduate levels. The knowledge gained from case studies of students using our CVA techniques feeds back into further development of our computational theory. Keywords: artificial intelligence, knowledge representation, reading, reasoning, science education, vocabulary acquisition. (shrink)

Given the widening gap between the number of individuals on transplant waiting lists and the availability of donated organs, as well as the recent plateau in donations based on neurological criteria, there has been a growing interest in expanding donation after circulatory determination of death. While the prevalence of this form of organ donation continues to increase, many thorny ethical issues remain, often creating moral distress in both clinicians and families. In this article, we address one of these issues, namely, (...) the challenges surrounding patient and surrogate informed consent for donation after circulatory determination of death. First we discuss several general concerns regarding consent related to this form of organ donation, and then we address additional issues that are unique to three different patient categories: adult patients with medical decision-making capacity or potential capacity, adult patients who lack capacity, and pediatric patients.

What is social justice? At this point, there is considerable disagreement. For many, the term social justice is baffling and useless, with no real meaning. Most who use it argue that social justice is the moral fairness of the system of rules and norms that govern society. Do these rules work so that all persons get what is due to them as human beings and as members of the community? Shifting from the will of individuals in rendering justice to the (...) outcome of the system of rules in achieving justice can be a dangerous leap. To some, it suggests that virtually every inequality arises because the rules of the game are unfair and that the state must intervene whenever there are unequal outcomes. The dangers of this leap are the primary focus of Is Social Justice Just?, whose twenty-one authors accepted an invitation to "explore, reassess, and critique the concept of social justice-relating it to ongoing debates in economics, history, philosophy, politics, public policy, religion, and the broader culture.".

Essays from both the left and right examine the wide range of issues surrounding the debates over political correctness and multiculturalism.

Research supporting social and emotional learning in schools demonstrates numerous benefits for students, including increased academic achievement and social and emotional competencies. However, research supporting the adoption of SEL lacks a clear conception of ethical competence. This lack of clarity is problematic for two reasons. First, it contributes to the conflation of social, emotional, and ethical competencies. Second, as a result, insufficient attention is paid to the related, yet distinct, ends of social-emotional and ethical education. While supporting SEL we critique (...) the assumption of uniformity between social-emotional and ethical literacy and argue for the significance of educational programming to support ethical competencies alongside or within SEL, including educating children to develop an autonomous ethical orientation. Doing so would advance the efforts of educators to provide an education for the whole child. (shrink)

In our essay we trace the evolution of the critical theory of religion, or comparative dialectical religiology, out of the critical theory of society of the Institute for Social Research or the Frankfurt School. For us, the history of religions reflects the history of humanity’s intellectual and spiritual evolution. As we developed our critical theory of religion, we have tried to supersede concretely the great accomplishments of three generations of critical theorists, particularly in the field of religion. One main theme (...) of our critical theory of religion is the dialectic of two modes of existence: having and being; egoism and altruism. As we determinately negated the critical theory of society into our comparative dialectical religiology, we also penetrated deeper into its roots in the works of Kant and Hegel, Marx and Freud, Judaism and Christianity, particularly into the mystical theology of the great dialectician Meister Eckhart and of his many modern followers. We conclude our essay with the vision of the City of Being. (shrink)

Drawing on conceptual works by Murphy (1999) and Solomon (1999), we develop a virtue ethics scale. Other ethics scales, which are grounded in deontological and teleological principles, may be used to classify people according to their beliefs about (1) the criteria they use to make ethical decisions, or (2) the ethicality of those decisions. We suggest augmenting these scales with our virtue ethics scale, which may be used to classify people according to their beliefs about the virtuous qualities of businesspeople.

The report of the President's Council on Bioethics, Human Cloning and Human Dignity, addresses the central ethical, political, and policy issue in human embryonic stem cell research: the moral status of extracorporeal human embryos. The Council members were in sharp disagreement on this issue and essentially failed to adequately engage and respectfully acknowledge each others' deepest moral concerns, despite their stated commitment to do so. This essay provides a detailed critique of the two extreme views on the Council (i.e., embryos (...) have full moral status or they have none at all) and then gives theoretical grounding for our judgment about the intermediate moral status of embryos. It also supplies an account of how to address profound moral disagreements in the public arena, especially by way of constructing a middle ground that deliberately pays sincere respect to the views of those with whom it has deep disagreements.

This paper focuses on the inheritance of human handedness and cerebral lateralization within the more general context of structural biological asymmetries. The morphogenesis of asymmetrical structures, such as the heart in vertebrates, depends upon a complex interaction between information coded in the cytoplasm and in the genes, but the polarity of asymmetry seems to depend on the cytoplasmic rather than the genetic code. Indeed it is extremely difficult to find clear-cut examples in which thedirectionof an asymmetry is under genetic control. (...) As one possible case, there is some evidence that the direction, clockwise or counterclockwise, of rotation of the abdomen in certain mutant strains ofDrosophilais controlled by a particular gene locus, although there appears to be some degree of confusion on this point. By contrast, it is much easier to find examples in which thedegreebut not the direction of asymmetry is under genetic control. For instance, there is a mutant strain of mice in which half of the animals displaysitus inversusof the viscera. The proportion has remained at one half despite many years of inbreeding, suggesting that the mutant allele effectively cancels the normalsitusand allows the asymmetry to be specified in random fashion.Although this account does not deny that the right hemisphere of humans may be the more specialized for certain functions, it does attribute a leading or dominant role to the left hemisphere (at least in most individuals). We suggest that so-called “right-hemisphere” functions are essentially acquired by default, due to the left hemisphere's prior involvement with speech and skilled motor acts; we note, for instance, that these right-hemisphere functions include rather elementary perceptual processes. But perhaps the more critical prediction from our account is that the phenomenon of equipotentiality should be unidirectional: the right (lagging) hemisphere should be more disposed to take over left-hemisphere functions following early lesions than is the left (leading) hemisphere to take over right-hemisphere functions. We note preliminary evidence that this may be so. (shrink)

A common strategy in bioethics is to posit a prima facie case in favour of one policy, and to then claim that the burden of proof falls on those with opposing views. If the burden of proof is not met, it is claimed, then the policy in question should be accepted. This article illustrates, and critically evaluates, examples of this strategy in debates about the sale of organs by living donors, human enhancement, and the precautionary principle. We highlight general problems (...) with this style of argument, and particular problems with its use in specific cases. We conclude that the burden ultimately falls on decision-makers to choose the policy supported by the best reasons. (shrink)

An Introduction to the Philosophy of Religion provides a broad overview of the topics which are at the forefront of discussion in contemporary philosophy of religion. Prominent views and arguments from both historical and contemporary authors are discussed and analyzed. The book treats all of the central topics in the field, including the coherence of the divine attributes, theistic and atheistic arguments, faith and reason, religion and ethics, miracles, human freedom and divine providence, science and religion, and immortality. In addition (...) it addresses topics of significant importance that similar books often ignore, including the argument for atheism from hiddenness, the coherence of the doctrines of the Trinity and the Incarnation, and the relationship between religion and politics. It will be a valuable accompaniment to undergraduate and introductory graduate-level courses. (shrink)

Pylyshyn is willing to assume that attention can influence feature integration. We argue that he concedes too much. Feature integration occurs preattentively, except in the case of certain “perverse” displays, such as those used in feature-conjunction searches.

There are two intriguing paradoxes in molecular biology-the inconsistent relationship between organismal complexity and (1) cellular DNA content and (2) the number of protein-coding genes-referred to as the C-value and G-value paradoxes, respectively. The C-value paradox may be largely explained by varying ploidy. The G-value paradox is more problematic, as the extent of protein coding sequence remains relatively static over a wide range of developmental complexity. We show by analysis of sequenced genomes that the relative amount of non-protein-coding sequence increases (...) consistently with complexity. We also show that the distribution of introns in complex organisms is non-random. Genes composed of large amounts of intronic sequence are significantly overrepresented amongst genes that are highly expressed in the nervous system, and amongst genes downregulated in embryonic stem cells and cancers. We suggest that the informational paradox in complex organisms may be explained by the expansion of cis-acting regulatory elements and genes specifying trans-acting non-protein-coding RNAs. (shrink)

We asked whether and how generations vary in their perceptions on moral matters ranging from their justifications of crime and questions concerning bodily autonomy. In our exploratory study using data from the World Values Survey, we found that Generations Y and Z are more likely than their older counterparts to justify crimes, such as cheating on taxes or stealing property, and to favor greater bodily autonomy in issues such as suicide and abortion. They also rank lower the importance of God (...) and national pride. Implications are offered for employers who wish to motivate and incentivize a multi-generational workforce. (shrink)

One of the most interesting challenges facing paleobiologists is explaining the Cambrian explosion, the dramatic appearance of most metazoan animal phyla in the Early Cambrian, and the subsequent stability of these body plans over the ensuing 530 million years. We propose that because phenotypic variation decreases through geologic time, because microRNAs (miRNAs) increase genic precision, by turning an imprecise number of mRNA transcripts into a more precise number of protein molecules, and because miRNAs are continuously being added to metazoan genomes (...) through geologic time, miRNAs might be instrumental in the canalization of development. Further, miRNAs ultimately allow for natural selection to elaborate morphological complexity, because by reducing gene expression variability, miRNAs increase heritability, allowing selection to change characters more effectively. Hence, miRNAs might play an important role in shaping metazoan macroevolution, and might be part of the solution to the Cambrian conundrum. (shrink)

We present an investigation into the relation between design princi- ples in Japanese gardens, and their associated perceptual effects. This leads to the realization that a set of design principles described in a Japanese gardening text by Shingen (1466), shows many parallels to the visual effects of perceptual grouping, studied by the Gestalt school of psychology. Guidelines for composition of rock clusters closely relate to perception of visual figure. Garden design elements are arranged into patterns that simplify figure-ground segmentation, while (...) seemingly balancing the visual salience of subparts and the global arrangement. Visual ‘ground’ is analyzed via medial axis transformation (MAT), often associated with shape perception in humans. MAT analysis reveals implicit structure in the visual ground of a quintessential rock garden design. The MAT structure enables formal com- parison of structure of figure and ground. They share some aesthetic qualities, with interesting differences. Both contain naturalistic asymmetric, self-similar, branching structures. While the branching pattern of the ground converges towards the viewer, that of the figure converges in the opposite direction. (shrink)

In this article we aim to open a new line of debate about religion in public schools by focusing on religious ideals. We begin with an elucidation of the concept ‘religious ideals’ and an explanation of the notion of reasonable pluralism, in order to be able to explore the dangers and positive contributions of religious ideals and their pursuit on a liberal democratic society. We draw our examples of religious ideals from Christianity and Islam, because these religions have most adherents (...) in Western liberal democracies that are the focus of this article. The fifth and most important section ‘‘Reasonable pluralism and the inclusion of religious ideals in public secondary schools’’ provides three arguments for our claim that public schools should include religious ideals, namely that they are important to religious people, that they are conducive for the development of pupils into citizens of a liberal democracy, and that the flourishing of pupils as adults is advanced by encountering religious ideals. We also offer a more practical reason: religious ideals can more easily be included within public education than religious dogmas and rules. (shrink)

Using practical formalism a deontological ethical analysis of peer relations in organizations is developed. This analysis is composed of two types of duties derived from Kant's Categorical Imperative: negative duties to refrain from the use of peers and positive duties to provide help and assistance. The conditions under which these duties pertain are specified through the development of examples and conceptual distinctions. A number of implications are then discussed.

This paper discusses recent neuroscientific research that indicates a solution for what we label the ''causal problem'' of pain qualia, the problem of how the brain generates pain qualia. In particular, the data suggest that pain qualia naturally supervene on activity in a specific brain region: the anterior cingulate cortex (ACC). The first section of this paper discusses several philosophical concerns regarding the nature of pain qualia. The second section overviews the current state of knowledge regarding the neuroanatomy and physiology (...) of pain processing. The third section highlights the recent research by Rainville et al. [(1997) Pain affect encoded in human anterior cingulate but not somatosensory cortex, Science, 277, 968-971], which suggests that pain affect is encoded in the ACC. The final section of the paper spells out exactly how these data affect the causal problem of pain qualia. (shrink)

Although the pedagogy literature indicates significant relationships between cheating intentions and both personal and situational factors, no published research has examined the joint effect of personal moral philosophy and perceived moral intensity components on students’ cheating intentions. Hence, a structural equation model that relates magnitude of consequences, relativism, and idealism to willingness to cheat, is developed and tested. Using data from undergraduate business students, the empirical results provide insight into these relationships and evidence of mediation for magnitude of consequences on (...) idealism and students’ cheating intentions. Implications for educators are offered. (shrink)
