Current research suggests consumers trade off price, quality, and sustainability attributes when making choices. Prior studies have typically focused on product attribute dyads, rather than multiattribute decision-making in the sustainability context. For scholars and practitioners, understanding which attributes are more important to consumers in tradeoff contexts has been a challenge. Self-other orientation may play a significant role in predicting consumers’ sustainable choices. We use prior research on equity sensitivity to demonstrate that segmenting consumers by their disposition to self-other tradeoffs helps (...) predict price–quality–sustainability tradeoffs. We hypothesize and test how members of these equity sensitivity segments tradeoff price, quality, and sustainability attributes in consumption decisions. Through four conjoint studies featuring diverse product assortments and sustainability issues, we find that price provides high utility for Entitled consumers, while sustainability provides high utility for Benevolent consumers. When product attributes are combined, Benevolents are more likely than Entitleds to purchase sustainable products. We also demonstrate that, in the absence of product choices, Equity Sensitives are more willing to choose a sustainable option over a conventional option, even when prices are high. In light of these findings, we discuss the implications for scholars looking to broadly predict consumers’ sustainable choices and for firms looking to target consumers with consumer-centric sustainability strategy.

This paper proposes an explanation in terms of three kinds of freedom, first for the special efficacy of science in general and then for why such efficacy has been more impressive in the natural than the social sciences. This explanation thus complements "post-positivist" interpretations of science which argue that science's effectiveness cannot be accounted for by fundamental epistemic differences from other kinds of discourse. My explanation tries to say what is responsible for science's effectiveness, in purely nonepistemic, sociological terms. All (...) of the three kinds of freedom have so far been denied to most other forums, including in particular nations' populations taken overall. And one of these freedoms, while now allowed to the natural sciences, is still denied to the social sciences. (shrink)

Sacrifice haunts the Phaedo. In this article, I argue that the mise-en-scène of the death scene of the Phaedo, as well as other sacrificial elements in the background of the dialogue, creates a nexus that positively integrates the birth, philosophical practice, and death of Socrates into the ritualized rhythm of the life of the city of Athens. A close reading of the death scene presented as a synopsis with Walter Burkert’s well-known analysis of Greek sacrifice reveals convergences and divergences between (...) the Phaedo and Greek sacrificial practice. Socrates appears as a willing victim who accepts the city’s sacrificial practice while remaining on his own terms. (shrink)

Models of risk-taking as used in the social sciences may be improved by including concepts from life history theory, particularly environmental unpredictability and life expectancy. Community college students completed self-report questionnaires measuring these constructs along with several well-known correlates. The frequency of risk-taking was higher for those with higher future unpredictability beliefs and shorter lifespan estimates (as measured by the Future Lifespan Assessment developed for this study), and unpredictability beliefs remained significant after accounting for standard predictors, such as sex and (...) temperament. The results demonstrate the usefulness of applying concepts from life history theory to enhance our understanding of human behavior. (shrink)

Forty-two essays by authors from five continents and many disciplines provide a synthetic account of the history of the social sciences-including behavioral and economic sciences since the late eighteenth century. The authors emphasize the cultural and intellectual preconditions of social science, and its contested but important role in the history of the modern world. While there are many historical books on particular disciplines, there are very few about the social sciences generally, and none that deal with so much of the (...) world over so long a timespan.

Upshot: Albeit mostly supportive of our work, the commentaries we received highlighted a few points that deserve additional explanation, with regard to the notion of learning in our model, the relationship between our model and the brain, as well as the notion of anticipation. This open discussion emphasizes the need for toy computer models, to fuel theoretical discussion and prevent business-as-usual from getting in the way of new ideas.

Context: Constructivist approaches to cognition have mostly been descriptive, and now face the challenge of specifying the mechanisms that may support the acquisition of knowledge. Departing from cognitivism, however, requires the development of a new functional framework that will support causal, powerful and goal-directed behavior in the context of the interaction between the organism and the environment. Problem: The properties affecting the computational power of this interaction are, however, unclear, and may include partial information from the environment, exploration, distributed processing (...) and aggregation of information, emergence of knowledge and directedness towards relevant information. Method: We posit that one path towards such a framework may be grounded in these properties, supported by dynamical systems. To assess this hypothesis, we describe computational models inspired from swarm intelligence, which we use as a metaphor to explore the practical implications of the properties highlighted. Results: Our results demonstrate that these properties may serve as the basis for complex operations, yielding the elaboration of knowledge and goal-directed behavior. Implications: This work highlights aspects of interaction that we believe ought to be taken into account when characterizing the possible mechanisms underlying cognition. The scope of the models we describe cannot go beyond that of a metaphor, however, and future work, theoretical and experimental, is required for further insight into the functional role of interaction with the environment for the elaboration of complex behavior. Constructivist content: Inspiration for this work stems from the constructivist impetus to account for knowledge acquisition based on interaction. (shrink)

John F. Kavanaugh and W. Norris Clarke, two twentieth-century Jesuits, contributed to philosophy through their development of a Thomistic and personalist view of reality emphasizing the human endowments of knowing, freely choosing, and loving. While spiritual exercises played a role in the formation of both Jesuits, the function of spiritual exercises in their own philosophy has not been explored. Recent interest in philosophy as a way of life provides a means by which this can be accomplished. In their work Michel (...) Foucault and Pierre Hadot have shown how spiritual exercises function in the formation of the self and in the acquisition of a synoptic vision that allows contemplation of one’s participation in the whole. This paper shows that while Kavanaugh primarily uses spiritual exercises in his philosophy to accomplish a disciplinary/formational aim Clarke’s aim is dialogical/exploratory. A brief examination of the Spiritual Exercises of Ignatius of Loyola reveals how these different aims in fact complement one another. (shrink)

Boyer & Petersen argue that folk-economic beliefs are widespread – shaped by evolved cognitive systems – and they offer exemplar beliefs to illustrate their thesis. In this commentary, we highlight evidence of substantial variation in one of these exemplars: beliefs about immigration. Contra claims by B&P, we argue that the balance of this evidence suggests the “folk” may actually holdpositivebeliefs about the economic impact of immigration.

This paper does not mean to imply that it is only public controversy that can meaningfully affect political outcomes, or even that it is the most important factor. Rather, we have attempted to indicate that public controversy constitutes a forum on which political actorsact; on which they attempt to implicate each other and the public in terms of some preferred view of the controversy at hand. It is certainly the case that the formal structure of the government and power relationships (...) provides important constraints in terms of which controversy may take place. Yet within these constraints, actors can meaningfully construct various views of the structure of the controversy which differently construe the rights and obligations of participants. In this sense, the course of public controversy may in part be understood as a function of the language employed by these actors, both to the extent that particular expressions stand as documentary evidence of underlying discrepancies about the shape of the controversy and to the extent that the logic of certain speech-acts constrains the forms subsequent statements may take.

In a reflective and richly entertaining piece from 1979, Doug Hofstadter playfully imagined a conversation between ‘Achilles’ and an anthill (the eponymous ‘Aunt Hillary’), in which he famously explored many ideas and themes related to cognition and consciousness. For Hofstadter, the anthill is able to carry on a conversation because the ants that compose it play roughly the same role that neurons play in human languaging; unfortunately, Hofstadter’s work is notably short on detail suggesting how this magic might be achieved1. (...) Conversely in this paper - finally reifying Hofstadter’s imagination - we demonstrate how populations of simple ant-like creatures can be organised to solve complex problems; problems that involve the use of forward planning and strategy. Specifically we will demonstrate that populations of such creatures can be configured to play a strategically strong - though tactically weak - game of HeX (a complex strategic game).We subsequently demonstrate how tactical play can be improved by introducing a form of forward planning instantiated via multiple populations of agents; a technique that can be compared to the dynamics of interacting populations of social insects via the concept of meta-population. In this way although, pace Hofstadter, we do not establish that a meta-population of ants could actually hold a conversation with Achilles, we do successfully introduce Aunt Hillary to the complex, seductive charms of HeX.

Recent studies suggest that vertebrate genetic material ingested by invertebrates (iDNA) can be used to investigate vertebrate ecology. Given the ubiquity of invertebrates that feed on vertebrates across the globe, iDNA might qualify as a very powerful tool for 21st century population and conservation biologists. Here, we identify some invertebrate characteristics that will likely influence iDNA retrieval and elaborate on the potential uses of invertebrate‐derived information. We hypothesize that beyond inventorying local faunal diversity, iDNA should allow for more profound insights (...) into wildlife population density, size, mortality, and infectious agents. Based on the similarities of iDNA with other low‐quality sources of DNA, a general technical framework for iDNA analyses is proposed. As it is likely that no such thing as a single ideal iDNA sampler exists, forthcoming research efforts should aim at cataloguing invertebrate properties relevant to iDNA retrieval so as to guide future usage of the invertebrate tool box.

Have you noticed that kids drop everything when T.V. commercials come on? Action ceases, conversations subside; I have even seen food fall from kids' immobilized lips. Isn't it interesting how kids can forget what we taught them yesterday, but months or even years later can remember "Two all beef patties, special sauce, lettuce, cheese, pickles, onions, on a sesame seed bun" or how to spell relief? Wouldn't it be great if they would pay teachers the attention they give commercials?

"OLD TESTS ARE BEST FORGOTTEN!" Ay least that is what most students believe. "You finish your test, your teacher 'gives' you your grade and you'll never have to remember that stuff again!" It's too bad that students regard tests to narrowly. But aren't such attitudes cultivated by the popular treatment of tests as ends in themselves? For example, when is the last time you studied the traffic safety rules for your state? Probably it was thefirst time you studied them in (...) preparation for your driver's license exam. When you passed the test, did you seek out the correct answers to the ones you missed? Probably not; it would have seemed unnecessary, since you "passed." Ever wonder about the questions that surgeons or airplane pilots missed, but failed to inquire about afterwards? (shrink)

We disagree with two of Rendell and Whitehead's assertions. Culture may be an ancestral characteristic of terrestrial cetacean ancestors; not derived via marine variability, modern cetacean mobility, or any living cetacean social structure. Furthermore, evidence for vocal behavior as culture, social stability, and cognitive ability, is richer in birds than Rendell and Whitehead portray and comparable to that of cetaceans and primates.

General Equilibrium Theory: An Introduction treats the classic Arrow-Debreu general equilibrium model in a form accessible to graduate students and advanced undergraduates in economics and mathematics. Topics covered include mathematical preliminaries, households and firms, existence of general equilibrium, Pareto efficiency of general equilibrium, the First and Second Fundamental Theorems of Welfare Economics, the core and core convergences, future markets over time and contingent commodity markets under uncertainty. Demand, supply, and excess demand appear first as functions, then optionally as correspondences. The (...) mathematics presented includes a real analysis, the Brouwer fixed point theorem, and separating and supporting hyperplane theorems. Optional chapters introduce the existence of equilibrium with set-valued supply and demand, the mathematics of upper and lower hemicontinuous correspondences, and the Kakutani fixed point theorem. The treatment emphasizes clarity and accessibility to the student through use of examples and intuition. (shrink)
