Many scientific discoveries have depended on external diagrams or visualizations. Many scientists also report to use an internal mental representation or mental imagery to help them solve problems and reason. How do scientists connect these internal and external representations? We examined working scientists as they worked on external scientific visualizations. We coded the number and type of spatial transformations (mental operations that scientists used on internal or external representations or images) and found that there were a very large number of (...) comparisons, either between different visualizations or between a visualization and the scientists’ internal mental representation. We found that when scientists compared visualization to visualization, the comparisons were based primarily on features. However, when scientists compared a visualization to their mental representation, they were attempting to align the two representations. We suggest that this alignment process is how scientists connect internal and external representations. (shrink)

The term conceptual simulation refers to a type of everyday reasoning strategy commonly called “what if” reasoning. It has been suggested in a number of contexts that this type of reasoning plays an important role in scientific discovery; however, little direct evidence exists to support this claim. This article proposes that conceptual simulation is likely to be used in situations of informational uncertainty, and may be used to help scientists resolve that uncertainty. We conducted two studies to investigate the relationship (...) between conceptual simulation and informational uncertainty. Study 1 was an in vivo study of expert scientists; the results suggest that scientists do use conceptual simulation in situations of informational uncertainty, and that they use conceptual simulation to make inferences from their data using the analogical reasoning process of alignment by similarity detection. Study 2 experimentally manipulated experts' level of uncertainty and provides further support for the hypothesis that conceptual simulation is more likely to be used in situations of informational uncertainty. Finally, we discuss the relationship between conceptual simulation and other types of reasoning using qualitative mental models. (shrink)

We conducted two in vivo studies to explore how scientists respond to anomalies. Based on prior research, we identify three candidate strategies: mental simulation, mental manipulation of an image, and comparison between images. In Study 1, we compared experts in basic and applied domains (physics and meteorology). We found that the basic scientists used mental simulation to resolve an anomaly, whereas applied science practitioners mentally manipulated the image. In Study 2, we compared novice and expert meteorologists. We found that unlike (...) experts, novices used comparison to address anomalies. We discuss the nature of expertise in the two kinds of science, the relationship between the type of science and the task performed, and the relationship of the strategies investigated to scientific creativity.

A growing body of literature has identified potential problems that can compromise the quality, fairness, and integrity of journal peer review, including inadequate review, inconsistent reviewer reports, reviewer biases, and ethical transgressions by reviewers. We examine the evidence concerning these problems and discuss proposed reforms, including double-blind and open review. Regardless of the outcome of additional research or attempts at reforming the system, it is clear that editors are the linchpin of peer review, since they make decisions that have a (...) significant impact on the process and its outcome. We consider some of the steps editors should take to promote quality, fairness and integrity in different stages of the peer review process and make some recommendations for editorial conduct and decision-making.

The neglect of issues related to the economic status of minorities and women in introductory economics textbooks widely used in the United States is a problem rooted in the most fundamental theoretical propositions of mainstream economics. Despite the fact that the claims of both mainstream methodology and general equilibrium theory have been seriously questioned in recent years, introductory economics textbooks fail to incorporate into the principles curriculum those critical findings which would allow analysis of the economic problems of women and (...) minorities in the United States. This article compares mainstream and radical textbooks' treatments of race and gender issues to show how the radical approach to these economic questions overcomes many of the deficiencies of the mainstream approach.

If Savulescu and Kahane’s Principle of Procreative Beneficence were implemented regarding cognitive enhancement, the result would be highly impoverishing for future children. For, apart from being inadequate to rationality itself, advocates’ accounts of cognitive enhancement sever reason from the input to judgments and decision-making that other faculties provide. When handling desire, supporters of cognitive enhancement frame conflicts between reason and the nonrational in terms of self-governance or akratic failure, depending on which one triumphs. Further, so-called negative emotions are treated as (...) simply deleterious and hostile to the rational. Alliances of the nonrational with reason toward shared ends are hence unthinkable. Having critiqued advocates’ views directly, I amplify my assessment through engagement with Aristotle’s Nicomachean Ethics. Per Savulescu and Kahane, to know how to direct enhancement endeavors, “we need to form reasonable opinions on difficult questions about the nature of well-being and the good life.” Thus far, however, enhancement supporters have been largely silent on this crucial matter. Because the debate over enhancement is ultimately over what values our views of flourishing embody, it should be recast so that this crux is squarely at the fore. What is more, for our own and our children’s sakes, as we embark on this reframing, we would do well to bear in mind Aristotle’s insights about the nonrational in relation to reason and his unwavering focus on the human “that for the sake of which” (hou heneka) all that we do is, perforce, undertaken.

How we assess current calls for vigorous, or “radical”, enhancement through befitting procreative choices depends in part on the plausibility of supporters’ rejecting all substantive ties between their views and earlier eugenics. When denying such connections, today’s advocates of vigorous enhancement routinely emphasize that enhancement decisions would stem from individuals and families, not the state. In a multipronged critique, I show the untenability of transhumanists’ denials.

This study examined more than 2,500 war images from U.S. television news, newspapers, news magazines, and online news sites during the first five weeks of the U.S.-led invasion of Iraq in 2003 and found that only 10% showed injury or death. The paper analyzes which media platforms were most willing to show casualties and offers insights on when journalists should use gruesome war images or keep them secret.

The cytoskeleton has a central role in eukaryotic biology, enabling cells to organize internally, polarize, and translocate. Studying cytoskeletal machinery across the tree of life can identify common elements, illuminate fundamental mechanisms, and provide insight into processes specific to less‐characterized organisms. Red algae represent an ancient lineage that is diverse, ecologically significant, and biomedically relevant. Recent genomic analysis shows that red algae have a surprising paucity of cytoskeletal elements, particularly molecular motors. Here, we review the genomic and cell biological evidence (...) and propose testable models of how red algal cells might perform processes including cell motility, cytokinesis, intracellular transport, and secretion, given their reduced cytoskeletons. In addition to enhancing understanding of red algae and lineages that evolved from red algal endosymbioses (e.g., apicomplexan parasites), these ideas may also provide insight into cytoskeletal processes in animal cells.

Susan B. Levin argues that Plato's engagement with medicine is richer than previously recognized and that he views it as an important rival for authority on nature and flourishing. Levin shows further that Plato's work, particularly the Laws, holds significant promise for bioethics that has so far been nearly untapped.

Who should decide? In When Doctors Say No, philosopher and bioethicist Rubin examines this controversial issue.

Genomic research results and incidental findings with health implications for a research participant are of potential interest not only to the participant, but also to the participant's family. Yet investigators lack guidance on return of results to relatives, including after the participant's death. In this paper, a national working group offers consensus analysis and recommendations, including an ethical framework to guide investigators in managing this challenging issue, before and after the participant's death.

In this study, Levin explores Plato's engagement with the Greek literary tradition in his treatment of key linguistic issues. This investigation, conjoined with a new interpretation of the Republic's familiar critique of poets, supports the view that Plato's work represents a valuable precedent for contemporary reflections on ways in which philosophy might benefit from appeals to literature.

To reassure those concerned about wholesale discontinuity between human existence and posthumanity, transhumanists assert shared ground with antiquity on vital challenges and aspirations. Because their claims reflect key misconceptions, there is no shared vision for transhumanists to invoke. Having exposed their misuses of Prometheus, Plato, and Aristotle, I show that not only do transhumanists and antiquity crucially diverge on our relation to ideals, contrast-dependent aspiration, and worthy endeavors but that illumining this divide exposes central weaknesses in transhumanist argumentation. What is (...) more, antiquity’s handling of these topics suggests a way through the impasse in current enhancement debates about human “nature” and helps to resolve a tension within transhumanists’ accounts of what our best moments signify about the ontological requirements for real flourishing.

Transhumanists would have humanity's creation of posthumanity be our governing aim. Susan B. Levin challenges their overarching commitments regarding the mind, brain, ethics, liberal democracy, knowledge, and reality. Her critique unmasks their notion of humanity's self-transcendence via science and technology as pure, albeit seductive, fantasy.

Advocates of cognitive enhancement maintain that technological advances would augment autonomy indirectly by expanding the range of options available to individuals, while, in a recent article in this journal, Schaefer, Kahane, and Savulescu propose that cognitive enhancement would improve it more directly. Here, autonomy, construed in broad procedural terms, is at the fore. In contrast, when lauding the goodness of enhancement expressly, supporters’ line of argument is utilitarian, of an ideal variety. An inherent conflict results, for, within their utilitarian frame, (...) the content of rational, hence autonomous, choices is quite restricted. Further, advocates do not clearly indicate their relative emphasis between the often conflicting goals of maximizing benefit and avoiding harm. In practice, their construction of harms is highly expansive, for disabilities include any constraints that “rational” people would decline if it were technically possible to do so. For advocates, this means that where enhancement measures are available, those constraints become avoidable limitations, and not to remove them is to harm. The centrality of harm-avoidance and their ideal utilitarian frame entail sociopolitical requirements that enhancement defenders disallow when trumpeting autonomy in the vein of individual choice. Advocates have thus not done enough to support the claim that their views are wholly separate from earlier eugenics. (shrink)

According to transhumanists who urge the radical enhancement of human beings, humanity’s top priority should be engineering “posthumans,” whose features would include agelessness. Increasingly, transhumanism is critiqued on foundational grounds rather than based largely on anticipated results of its implementation, such as rising social inequality. This expansion is crucial but insufficient because, despite its radical aim, transhumanism reflects beliefs and attitudes that are evident in the broader culture. With a focus on the yearning to eliminate aging, I consider four of (...) these: a disproportionate reliance on science and technology to address major human challenges; the conceptualization of human beings in terms of binaries like “young-old”; a repudiation of vulnerability; and intensifying perfectionism. Illuminating these interlocked commitments both deepens an existing critique of transhumanism and draws our attention to deleterious cultural views that must be vigorously contested if our commitment to human flourishing is to be deep and unwavering.

Objective: The aim of this study was to examine the psychometric properties and factorial structure of the Schema Mode Inventory for Eating Disorders (SMI-ED) in a disordered eating population. Method: 573 participants with disordered eating patterns as measured by the Eating Disorder Examination Questionnaire (EDE-Q) completed the 190-item adapted version of the Schema Mode Inventory (SMI). The new SMI-ED was developed by clinicians/researchers specializing in the treatment of eating disorders, through combining items from the original SMI with a set of (...) additional questions specifically representative of the eating disorder population. Psychometric testing included Confirmatory Factor Analysis (CFA) and internal consistency (Cronbach’s α). Multivariate Analyses of Covariance (MANCOVA) was also run to test statistical differences between the EDE-Q subscales on the SMI-ED modes, while controlling for possible confounding variables. Results: Factorial analysis confirmed an acceptable sixteen-related-factors solution for the SMI-ED, thus providing preliminary evidence for the adequate validity of the new measure based on internal structure. Concurrent validity was also established through moderate to high correlations on the modes most relevant to eating disorders with EDE-Q subscales. This study represents the first step in creating a psychometrically sound instrument for measuring schema modes in eating disorders, and provides greater insight into the relevant schema modes within this population. Conclusion: This research represents an important preliminary step toward understanding and labeling the schema mode model for this clinical group. Findings from the psychometric evaluation of SMI-ED suggest that this is a useful tool which may further assist in the measurement and conceptualization of schema modes in this population. (shrink)

The most contentious issue in current debates about human enhancement is whether it properly belongs to human aspiration to outstrip our human ceiling in cognition and longevity so radically that the result would not be improved human beings but instead "posthumans." Transhumanists answer strongly in the affirmative and hence vigorously support our directing available and foreseeable technologies to that end. According to Nick Bostrom, transhumanism is "an outgrowth of secular humanism and the Enlightenment." Our "ceasing to be human is [not] (...) in any way problematic" as long as we are "replaced by something better".Of the two main lines of technological approach that... (shrink)

The debate about what constitutes the discipline of ethics and who qualifies as an ethics consultant is linked unavoidably to a debate that is potentiated by the reality of a rapidly changing and high-stakes health care consultation marketplace. Who we are and what we can offer to the moral gesture that is medicine is shaped by our fundamental understanding of the place of expert knowledge in the transformation of social reality. The struggle for self-definition is particularly freighted since clinical ethics (...) consultation aspires to be more than academic contemplation. Two recent books (Ethics Consultation by John La Puma and David Schiedermayer and The Health Care Ethics Consultant: A Practical Guide, edited by Francoise Baylis) exemplify the two most popular but most widely divergent positions on these issues. We argue that while useful, neither book addresses fully the particular and distinct role of the professional ethicist. (shrink)

In an analysis of 47 U.S. journalism ethics codes, we found that although most consider images, only 9 address a gripping issue: how to treat images of tragedy and violence, such as those produced on the battlefields of Iraq, during the 2005 London bombings, and after Hurricane Katrina. Among codes that consider violent and tragic images, there is agreement on what images are problematic and a move toward green-light considerations of ethical responsibilities. However, the special problems of violence and truth (...) telling in wartime and issues of how to handle graphic images across media platforms receive virtually no attention. (shrink)

Clinical ethics, like the broader field of bioethics from which it emerged, is at a critical crossroads in its development, with conflicting paths ahead. It can either claim its distinctive place in the clinical arena, insisting unapologetically on certain minimal standards of professional training, practice and competence, addressing head on debates about various models of and methodological approaches to consultation, and establishing a shared vision of the purpose and meaning of the enterprise of clinical ethics itself. Or, it can devolve (...) into a hobby that untrained, albeit interested, and generally well intentioned individuals can dabble in for fun or even profit, as they see fit, and without regard to the deep history and rich disciplinary roots of the field, the serious debates in the academic literature of bioethics, the foundational case histories and legal theories, or even any sense of professional accountability.
