In his most recent collection of papers, J. Baird Callicott has continued to advance a communitarian environmental ethic inspired by the mid–century "land ethic" writings of Aldo Leopold. One subject of concern is a dilemma. Either: the position is open to a charge of "eco–fascism" because it holds that only one maximal community fundamentally matters and interests of smaller communities and individuals can be swamped by a fundamental concern with the whole. Or: it is a "paper tiger" because it says that many communities fundamentally matter, but offers no advice about how we are settle prima–facie conflicts of obligations tied to our various communities. Callicott now offers two new second–order priority principles designed to steer the communitarian position through the dilemma. I outline the relevant parts of his new position. However, I argue that one of the principles ends up offering no coherent advice over the priority of the very communities that inspire interest in the position of Leopold. Callicott proposes that the more intimate and venerable of our communities should have priority, but these elements can come apart in the relevant cases  相似文献

There is a tendency in decision‐making research to treat uncertainty only as a problem to be overcome. But it is also a feature that can be leveraged, particularly in social interaction. Comparing the behavior of profitable and unprofitable poker players, we reveal a strategic use of information processing that keeps decision makers unpredictable. To win at poker, a player must exploit public signals from others. But using public inputs makes it easier for an observer to reconstruct that player's strategy and predict his or her behavior. How should players trade off between exploiting profitable opportunities and remaining unexploitable themselves? Using a recent multivariate approach to information theoretic data analysis and 1.75 million hands of online two‐player No‐Limit Texas Hold'em, we find that the important difference between winning and losing players is not in the amount of information they process, but how they process it. In particular, winning players are better at integrative information processing—creating new information from the interaction between their cards and their opponents’ signals. We argue that integrative information processing does not just produce better decisions, it makes decision‐making harder for others to reverse engineer, as an expert poker player's cards act like the private key in public‐key cryptography. Poker players encrypt their reasoning with the way they process information. The encryption function of integrative information processing makes it possible for players to exploit others while remaining unexploitable. By recognizing the act of information processing as a strategic behavior in its own right, we offer a detailed account of how experts use endemic uncertainty to conceal their intentions in high‐stakes competitive environments, and we highlight new opportunities between cognitive science, information theory, and game theory.  相似文献

Individuals and organizations frequently tout creative ideas as a desirable goal, and yet, creative ideas are frequently rejected. Creativity researchers have often suggested that creative ideas are rejected because they are perceived as riskier due to their inherent novelty or originality. Although this assumption is prevalent, we are unaware of any empirical research directly examining the relations between perceptions of novelty and risk. We provide an empirical test of this assumption in two studies in which participants rate the novelty, usefulness, and riskiness of ideas. Across both studies, we find consistent support for the idea that usefulness, rather than novelty, has the strongest relation with risk perceptions. We also find some evidence that novelty and usefulness interact to predict perceptions of risk. Additionally, in Study 2, we find that usefulness has the strongest relation with willingness to invest and buy a product. The findings of this study suggest that the bias against creativity may be driven by the perceived usefulness of an idea, rather than its novelty, such that ideas with lower usefulness are perceived to be riskier.  相似文献

Abstract

The present article introduces the special issue on identity in the former Soviet bloc countries. We begin by discussing identity as a developmental task, as well as the social-contextual forces that direct and constrain the ways in which individual people construct their identities. We then articulate some specific challenges inherent in identity development within contexts characterized by social change – primarily the fact that the available identity alternatives, and the ways in which individuals are expected to go about choosing from among these alternatives, are likely changing rapidly. We frame Erikson’s original work as having been grounded in times of rapid social change in the post-World War II United States, and describe the direct relevance of Erikson’s work for the study of more contemporary instances of sociopolitical change. We then introduce and summarize the articles included in the special issue.  相似文献

Few studies have examined comprehensively the ways in which men and women at risk for HIV infection influence their partners to use condoms. This study examines the condom influence strategies (CISs) of an ethnically diverse community sample of 113 (55% male) heterosexually active men and women. Results indicate that individuals at risk for HIV endorse a variety of CISs (withholding sex, direct request, seduction, relationship conceptualizing, risk information, deception, and pregnancy prevention) when attempting to procure condom use with a sexual partner. These CISs were related significantly and meaningfully to a set of safer sexual variables including 3 measures of condom use. Significant gender differences in CISs were not found. Results suggest that safer sexual behavior theories should continue to focus on interpersonal aspects of condom use and underscore the importance of an interpersonal approach to safer sexual intervention.  相似文献

This study evaluated the preliminary efficacy of a computer-based HIV intervention to enhance HIV-protective sexual behaviours, based on a randomised controlled trial among 135 African-American women, 21-29 years of age, seeking services at Planned Parenthood in Atlanta, GA. Participants were randomised either to a control session two, 60-minute computer-based HIV intervention sessions administered on a laptop computer that each concluded with a 15-minute small group session or to a control session of general health information including discussion on HIV prevention. Relative to controls, participants in the computer-based HIV intervention were more knowledgeable about HIV/STD prevention and reported higher scores on the measure of condom use self-efficacy at 3 months post-intervention; they also reported a higher percentage of condom-protected sex and were more likely to use condoms consistently for vaginal sex (odds ratio, OR = 5.9; p < 0.039) and were more likely to use condoms consistently for oral sex (OR = 13.83; p < 0.037). This relatively brief intervention provides preliminary support that an evidence-based group-based HIV prevention intervention for young African-American women can be adapted to a computer-based HIV intervention.  相似文献

Using case vignettes that differed in the presentation of the client's social class, the influence of social class on therapeutic impressions was studied in the context of just-world beliefs. Results suggested that (1) participants with higher levels of belief in a just world saw poor and working-class clients as more unpleasant to work with and more dysfunctional and (2) working-class vignettes were associated with the lowest predictions of session depth and smoothness. The findings suggest that counselors may respond differently to clients based on their social class, and in a way that negatively predisposes them toward work with poor and working-class clients.  相似文献

Can conscious awareness be ascertained from physiological responses alone? We evaluate a novel learning-based procedure permitting detection of conscious awareness without reliance on language comprehension or behavioural responses. The method exploits a situation whereby only consciously detected violations of an expectation alter skin conductance responses (SCRs). Thirty participants listened to sequences of piano notes that, without their being told, predicted a pleasant fanfare or an aversive noise according to an abstract rule. Stimuli were presented without distraction (attended), or while distracted by a visual task to remove awareness of the rule (unattended). A test phase included occasional violations of the rule. Only participants attending the sounds reported awareness of violations and only they showed significantly greater SCR for noise occurring in violation, vs. accordance, with the rule. Our results establish theoretically significant dissociations between conscious and unconscious processing and furnish new opportunities for clinical assessment of residual consciousness in patient populations.  相似文献
