John Locke's educational program has long been considered to have two primary aims: to habituate children to reason and to raise children capable of meeting the demands of citizenship that he details in his Two Treatises of Government. Yet Locke's educational prescriptions undermine citizens’ capacity for honesty, a critical political virtue for Locke. To explain how Locke's educational prescriptions are self-undermining, we turn to Rousseau's extended critique of Locke's Some Thoughts on Education in his Émile. We argue that Rousseau explains (...) why such an education allows a natural desire to dominate to flourish, rendering children who receive it dishonest and incapable of self-government. Rousseau's critique exposes how a liberal education focused solely on autonomy cannot produce the kinds of citizens a Lockean politics requires. (shrink)

This paper introduces a special issue of Cognitive Science initiated on the 25th anniversary of the publication of Parallel Distributed Processing (PDP), a two-volume work that introduced the use of neural network models as vehicles for understanding cognition. The collection surveys the core commitments of the PDP framework, the key issues the framework has addressed, and the debates the framework has spawned, and presents viewpoints on the current status of these issues. The articles focus on both historical roots and contemporary (...) developments in learning, optimality theory, perception, memory, language, conceptual knowledge, cognitive control, and consciousness. Here we consider the approach more generally, reviewing the original motivations, the resulting framework, and the central tenets of the underlying theory. We then evaluate the impact of PDP both on the field at large and within specific subdomains of cognitive science and consider the current role of PDP models within the broader landscape of contemporary theoretical frameworks in cognitive science. Looking to the future, we consider the implications for cognitive science of the recent success of machine learning systems called “deep networks”—systems that build on key ideas presented in the PDP volumes.

In this prcis we focus on phenomena central to the reaction against similarity-based theories that arose in the 1980s and that subsequently motivated the approach to semantic knowledge. Specifically, we consider (1) how concepts differentiate in early development, (2) why some groupings of items seem to form or coherent categories while others do not, (3) why different properties seem central or important to different concepts, (4) why children and adults sometimes attest to beliefs that seem to contradict their direct experience, (...) (5) how concepts reorganize between the ages of 4 and 10, and (6) the relationship between causal knowledge and semantic knowledge. The explanations our theory offers for these phenomena are illustrated with reference to a simple feed-forward connectionist model. The relationships between this simple model, the broader theory, and more general issues in cognitive science are discussed. (shrink)

The commentaries reflect three core themes that pertain not just to our theory, but to the enterprise of connectionist modeling more generally. The first concerns the relationship between a cognitive theory and an implemented computer model. Specifically, how does one determine, when a model departs from the theory it exemplifies, whether the departure is a useful simplification or a critical flaw? We argue that the answer to this question depends partially upon the model's intended function, and we suggest that connectionist (...) models have important functions beyond the commonly accepted goals of fitting data and making predictions. The second theme concerns perceived in-principle limitations of the connectionist approach to cognition, and the specific concerns these perceived limitations raise for our theory. We argue that the approach is not in fact limited in the ways our critics suggest. One common misconception, that connectionist models cannot address abstract or relational structure, is corrected through new simulations showing directly that such structure can be captured. The third theme concerns the relationship between parallel distributed processing (PDP) models and structured probabilistic approaches. In this case we argue that there the difference between the approaches is not merely one of levels. Our PDP approach differs from structured statistical approaches at all of Marr's levels, including the characterization of the goals of cognitive computations, and of the representations and algorithms used.

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.

Most empirical work in human categorization has studied learning in either fully supervised or fully unsupervised scenarios. Most real-world learning scenarios, however, are semi-supervised: Learners receive a great deal of unlabeled information from the world, coupled with occasional experiences in which items are directly labeled by a knowledgeable source. A large body of work in machine learning has investigated how learning can exploit both labeled and unlabeled data provided to a learner. Using equivalences between models found in human categorization and (...) machine learning research, we explain how these semi-supervised techniques can be applied to human learning. A series of experiments are described which show that semi-supervised learning models prove useful for explaining human behavior when exposed to both labeled and unlabeled data. We then discuss some machine learning models that do not have familiar human categorization counterparts. Finally, we discuss some challenges yet to be addressed in the use of semi-supervised models for modeling human categorization. (shrink)

Three experiments with 88 college-aged participants explored how unlabeled experiences—learning episodes in which people encounter objects without information about their category membership—influence beliefs about category structure. Participants performed a simple one-dimensional categorization task in a brief supervised learning phase, then made a large number of unsupervised categorization decisions about new items. In all three experiments, the unsupervised experience altered participants’ implicit and explicit mental category boundaries, their explicit beliefs about the most representative members of each category, and even their memory (...) for the items encountered during the supervised learning phase. These changes were influenced by both the range and frequency distribution of the unlabeled stimuli: mental category boundaries shifted toward the middle of the range and toward the trough of the bimodal distribution of unlabeled items, whereas beliefs about the most representative category members shifted toward the modes of the unlabeled distribution. One consequence of this shift in representations is a false-consensus effect (Experiment 3) where participants, despite receiving very disparate training experiences, show strong agreement in judgments about representativeness and boundary location following unsupervised category judgments.

This research empirically investigated the CSR practices of 84 Botswana and Malawi organizations. The findings revealed that the extent and type of CSR practices in these countries did not significantly differ from that proposed by a U. S. model of CSR, nor did they significantly differ between Botswana and Malawi. There were, however, differences between the sampled organizations that clustered into a stakeholder perspective and traditional capitalist model groups. In the latter group, the board of directors, owners, and shareholders were (...) important stakeholders that appeared to be restricting extended stakeholder CSR activities in the Malawi and Botswana organizations. The sampled managers recognized the economic benefits of CSR practices and were not at odds with social objectives. (shrink)

Ethical issues surrounding the marketing and trade of controversial products such as tobacco require a better understanding. Virginia Slims, an exclusively women’s cigarette brand first launched in 1968 in the USA, was introduced during the mid 1980s to major Asian markets, such as Japan and Korea, dominated by male smokers. By reviewing internal corporate documents, made public from litigation, we examine the marketing strategies used by Philip Morris as they entered new markets such as Japan and Korea and consider the (...) extent that the company attempted to appeal to women in markets where comparatively few women were smokers. The case study of Virginia Slims reveals that the classification of “vulnerable” consumers is variable depending on culture, tobacco firms display responsive efforts and strategies when operating within a “mature” market, and cultural values played a role in informing Philip Morris’ strategic decision to embrace an adaptive marketing approach, particularly when entering the Korean market. Finally, moral questions are raised with tobacco being identified as a priority product for export and international trade agreements being used by corporations, governments, or trade partners in efforts to undermine domestic public health policies.

The paper explores the main competing interpretations of Aristotle's view of the relation between happiness and external goods in the Nicomachean Ethics. On the basis of a careful analysis of what Aristotle says in the Nicomachean Ethics (and other works such as the Eudemian Ethics, Politics, Rhetoric, etc.) it is argued that it is likely that Aristotle takes at least some external goods to be actual constituents of happiness provided that (1) they are accompanied by virtuous activity and (2) the (...) agent enjoying and using those external goods does so in ways compatible with the continuous aim of acting virtuously.

Uchiyama et al. reveal how group-structured cultural variation influences measurements of trait heritability. We argue that understanding culture's influence on phenotypic heritability can clarify the impact of culture on genetic inheritance, which has implications for long-term gene–culture coevolution. Their analysis may provide guidance for testing our hypothesis that cultural adaptation is superseding genetic adaptation in the long term.

A large body of research links testosterone and cortisol to male-male competition. Yet, little work has explored acute steroid hormone responses to coalitional, physical competition during middle childhood. Here, we investigate testosterone, dehydroepiandrosterone, androstenedione, and cortisol release among ethnically Chinese boys in Hong Kong, aged 8–11 years, during a soccer match and an intrasquad soccer scrimmage, with 63 participants competing in both treatments. The soccer match and intrasquad soccer scrimmage represented out-group and in-group treatments, respectively. Results revealed that testosterone showed (...) no measurable change. DHEA increased during both treatments in the majority of participants and the degree of change had no relation to independent variables or covariate measures. Most boys experienced androstenedione increases during match play, but no significant differences during the intrasquad soccer scrimmage competitions. The magnitude of change differed significantly between treatments and was positively associated with age. These latter findings suggest boys’ androstenedione responses may be sensitive to competitor type. For most subjects, cortisol significantly increased during match play, decreased during the intrasquad soccer scrimmage, and differed significantly between treatments, suggesting each treatment promoted a different psychological state among competitors. Cortisol/DHEA molar ratio decreased during the intrasquad scrimmage, suggestive of a more relaxed mental state. These data shed new light on potential proximate mechanisms associated with coalitional competition among prepubescent boys, with relevance to adrenarche and life history theory. (shrink)

DNA helicases are a class of molecular motors that catalyze processive unwinding of double stranded DNA. In spite of much study, we know relatively little about the mechanisms by which these enzymes carry out the function for which they are named. Most current views are based on inferences from crystal structures. A prominent view is that the canonical ATPase motor exerts a force on the ssDNA resulting in “pulling” the duplex across a “pin” or “wedge” in the enzyme leading to (...) a mechanical separation of the two DNA strands. In such models, DNA base pair separation is tightly coupled to ssDNA translocation of the motors. However, recent studies of the Escherichia coli RecBCD helicase suggest an alternative model in which DNA base pair melting and ssDNA translocation occur separately. In this view, the enzyme‐DNA binding free energy is used to melt multiple DNA base pairs in an ATP‐independent manner, followed by ATP‐dependent translocation of the canonical motors along the newly formed ssDNA tracks. Repetition of these two steps results in processive DNA unwinding. We summarize recent evidence suggesting this mechanism for RecBCD helicase action. (shrink)

For half a century the idea of rational thought has been challenged by discoveries that call into question some of its foundations. How we actually think seems to be at odds with descriptive and prescriptive models that once held sway in the development of modern science and scholarship. One response to these challenges has been a loss of nerve. Another—the one on display in Rationality: Contexts and Constraints—is an active attempt to revise those models, so as to enhance their compatibility (...) with new discoveries, in a maximally coherent and inclusive way. Rationality: Contexts and Constraints is an inter-disciplinary reappraisal of the nature of rationality. In method it is pluralistic, drawing upon the analytic approaches of philosophy, linguistics, neuroscience, and more. These methods guide exploration of the intersection between hoary scholarship and cutting-edge philosophical or scientific research. In this way, Rationality: Contexts and Constraints contributes to development of a suitably revised, comprehensive understanding of rationality, one that befits the 21st century, one that is adequately informed by recent investigations of science, pathology, non-human thought, emotion, and even enigmatic Chinese texts that might previously have seemed to be expressions of irrationalism. • Addresses recent challenges and Identifies a direction for future research on rationality • Investigates the relationship between rationality and mental disorders such as delusion and depression • Assesses reasoning in artificial intelligence and nonhuman animals • Reflects on ancient Chinese Philosophy and possible cultural differences in human psychology • Employs philosophical reflection along with linguistic, probabilistic, and logical techniques -/- .

This 2005 volume brings together twelve papers by many of the most prominent applied general equilibrium modelers honoring Herbert Scarf, the father of equilibrium computation in economics. It deals with developments in applied general equilibrium, a field which has broadened greatly since the 1980s. The contributors discuss some traditional as well as some modern topics in the field, including non-convexities in economy-wide models, tax policy, developmental modeling and energy modeling. The book also covers a range of distinct approaches, conceptual issues (...) and computational algorithms, such as calibration and areas of application such as macroeconomics of real business cycles and finance. An introductory chapter written by the editors maps out issues and scenarios for the future evolution of applied general equilibrium. (shrink)

Four predictors were posited to affect business student attitudes about the social responsibilities of business, also known as corporate social responsibility (CSR). Applying Forsyth's (1980, "Journal of Personality and Social Psychology" 39, 175–184, 1992, "Journal of Business Ethics" 11, 461–470) personal moral philosophy model, we found that ethical idealism had a positive relationship with CSR attitudes, and ethical relativism a negative relationship. We also found materialism to be negatively related to CSR attitudes. Spirituality among business students did not significantly predict (...) CSR attitudes. Understanding the relationship between CSR attitudes and the significant predictors has important implications for researchers and teachers in particular. (shrink)

Social prescriptions are one term commonly used to describe non-pharmaceutical approaches to healthcare and are gaining popularity in the community, with evidence highlighting psychological benefits of reduced anxiety, depression and improved mood and physiological benefits of reduced risk of cardiovascular disease and reduced hypertension. The relationship between human health benefits and planetary health benefits is also noted. There are, however, numerous barriers, such as duration and frequencies to participate in activities, access, suitability, volition and a range of unpredictable variables impeding (...) a comprehensive approach to their use on a wider scale. From a multidisciplinary perspective, this commentary incorporates a salutogenic and nature-based approach to health, we also provide a range of recommendations that can be undertaken at the patient level to assist in shifting the acknowledged systemic barriers currently occurring. These include using simple language to explain the purpose of health empowerment scripts, ensuing personal commitment to a minimum timeframe, enabling ease of access, co-designing a script program, providing ongoing motivational support and incorporating mindfulness to counter unexpected disruptions.

ObjectiveTo further delineate risk and resilience factors contributing to trajectories of mental health symptoms experienced by college students through the pandemic.Participantsn = 183 college students.MethodsLinear mixed models examined time effects on depression and anxiety. Propensity-matched subgroups exhibiting “increased” versus “low and stable” depression symptoms from before to after the pandemic-onset were compared on pre-pandemic demographic and psychological factors and COVID-related experiences and coping strategies.ResultsStudents experienced worsening of mental health symptoms throughout the pandemic, particularly during Fall 2020 compared with Fall 2019. (...) The propensity-matched subgroup exhibiting relative resilience reported less alcohol use prior to the pandemic, greater use of active coping strategies, and less of an impact on their college progress.ConclusionsResults point to several potential targets of screening and intervention to decrease residual impacts of the pandemic.

© 2015, Springer-Verlag Berlin Heidelberg.Genetic studies have identified single nucleotide polymorphisms associated with the risk of prostate cancer. It remains unclear whether such genetic variants are associated with disease aggressiveness. The NCI-SPORE Genetics Working Group retrospectively collected clinicopathologic information and genotype data for 36 SNPs which at the time had been validated to be associated with PC risk from 25,674 cases with PC. Cases were grouped according to race, Gleason score and aggressiveness. Statistical analyses were used to compare the frequency (...) of the SNPs between different disease cohorts. After adjusting for multiple testing, only PC-risk SNP rs2735839 was significantly and inversely associated with aggressive and high-grade disease in European men. Similar associations with aggressive and high-grade disease were documented in African-American subjects. The G allele of rs2735839 was associated with disease aggressiveness even at low PSA levels in both European and African-American men. Our results provide further support that a PC-risk SNP rs2735839 near the KLK3 gene on chromosome 19q13 may be associated with aggressive and high-grade PC. Future prospectively designed, case-case GWAS are needed to identify additional SNPs associated with PC aggressiveness. (shrink)

Hume’s criticisms of divine causation are insufficient because he does not respond to important philosophical positions that are defended by those whom he closely read. Hume’s arguments might work against the background of a Cartesian definition of body, or a Malebranchian conception of causation, or some defenses of occasionalism. At least, I will not here argue that they succeed or fail against those targets. Instead, I will lay out two major deficiencies in his arguments against divine causation. I call these (...) “deficiencies” because Hume does not adequately address live positions. This does not mean, of course, that there are not problems with these views or that Hume could not have given strong arguments against them. Rather, Hume’s arguments, which can seem comprehensive to the twenty-first century reader, are in fact not so. For the deficiencies discussed in this essay, I point to writers from Hume’s near context (many of whom we know he read carefully) who held the views not discussed, and I provide reasons why Hume seems not to have entertained these possibilities. I won’t distinguish between accidentally overlooking and actively ignoring. By drawing attention to these three deficiencies, I have two goals. The first is to demonstrate the diversity of seventeenth and early eighteenth century views on divine causation, especially among philosophers in England, Scotland, and Ireland, who are often ignored by philosophers today who, like Hume, focus on continental Cartesians while ignoring British dualists and vitalists. The second goal is to make today’s readers aware of shortcomings in Hume’s arguments to encourage productively contextual readings of Hume and his contemporaries. (shrink)

In Fixing Language, Herman Cappelen defends the project of conceptual engineering from a family of objections that he calls “the Strawsonian challenges.” Those objections are all versions of this: “If I ask you a question about the F’s, and you give me an answer that’s not about the F’s but rather about the G’s, then you haven’t answered my question. You have changed the subject.” I argue that Cappelen’s response succeeds in reply to one understanding of the Strawsonian challenge—on which (...) it is motivated by ordinary judgments of samesaying and continuity of topic—but that it fails as a response to another version—on which a parallel objection is motivated by philosophical considerations and is stated in a theoretical register.

The shelves of film and philosophy books should have made it considerably easier to teach with films in introductory philosophy classes, and certainly many philosophers have found them useful. However, shortcomings of many of these pop culture volumes (which I discuss in the next section) make these works rarely useful in the classroom. I propose instead a new model for how to teach film in a philosophy class. The model develops the virtues inherent in cinephilia and connects those virtues to (...) the good life. (shrink)

In 1999, Jeffrey Ketland published a paper which posed a series of technical problems for deflationary theories of truth. Ketland argued that deflationism is incompatible with standard mathematical formalizations of truth, and he claimed that alternate deflationary formalizations are unable to explain some central uses of the truth predicate in mathematics. He also used Beth’s definability theorem to argue that, contrary to deflationists’ claims, the T-schema cannot provide an ‘implicit definition’ of truth. In this article, I want to challenge this (...) final argument. Whatever other faults deflationism may have, the T-schema does provide an implicit definition of the truth predicate. Or so, at any rate, I shall argue. (shrink)

Environmental ethicists have frequently criticized ancient Greek philosophy as anti-environmental for a view of philosophy that is counterproductive to environmental ethics and a view of the world that puts nature at the disposal of people. This provocative collection of original essays reexamines the views of nature and ecology found in the thought of Plato, Aristotle, the Stoics, and Plotinus. Recognizing that these thinkers were not confronted with the environmental degradation that threatens contemporary philosophers, the contributors to this book find that (...) the Greeks nevertheless provide an excellent foundation for a sound theory of environmentalism.

In an influential paper, Stephen Jay Gould and Richard Lewontin contrasted selection-driven adaptation with phylogenetic, architectural, and developmental constraints as distinct causes of phenotypic evolution. In subsequent publications Gould has elaborated this distinction into one between a narrow “Darwinian Fundamentalist” emphasis on “external functionalist” processes, and a more inclusive “pluralist” emphasis on “internal structuralist” principles. Although theoretical integration of functionalist and structuralist explanations is the ultimate aim, natural selection and internal constraints are treated as distinct causes of evolutionary change. This (...) distinction is now routinely taken for granted in the literature in evolutionary biology. I argue that this distinction is problematic because the effects attributed to non-selective constraints are more parsimoniously explained as the ordinary effects of selection itself. Although it may still be a useful shorthand to speak of phylogenetic, architectural, and developmental constraints on phenotypic evolution, it is important to understand that such “constraints” do not constitute an alternative set of causes of evolutionary change. The result of this analysis is a clearer understanding of the relationship between adaptation, selection and constraints as explanatory concepts in evolutionary theory. (shrink)
