Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

Critics of evolutionary psychology and sociobiology have advanced an adaptationists-as-right-wing-conspirators (ARC) hypothesis, suggesting that adaptationists use their research to support a right-wing political agenda. We report the first quantitative test of the ARC hypothesis based on an online survey of political and scientific attitudes among 168 US psychology Ph.D. students, 31 of whom self-identified as adaptationists and 137 others who identified with another non-adaptationist meta-theory. Results indicate that adaptationists are much less politically conservative than typical US citizens and no more (...) politically conservative than non-adaptationist graduate students. Also, contrary to the “adaptationists-as-pseudo-scientists” stereotype, adaptationists endorse more rigorous, progressive, quantitative scientific methods in the study of human behavior than non-adaptationists.

lecting statistics about missing bindings and macros, and other errors. This guides debugging and development efforts, leading to iterative improvements in both the tools and the quality of the converted corpus. The build system thus serves as both a production conversion engine and software test harness. We have now processed the complete arχiv collection through 2006 consisting of more than 400,000 documents (a complete run is a processor-yearsize undertaking), continuously improving our success rate. We are now able to convert more (...) than 90% of these documents to XHTML+MathML. We consider over 60% to be successes, converted with no or minor warnings. While the remaining 30% can also be converted, their quality is doubtful, due to unsupported macros or conversion errors. (shrink)

Judgment aggregation theory, which concerns the translation of individual judgments on logical propositions into consistent group judgments, has shown that group consistency generally cannot be guaranteed if each proposition is treated independently from the others. Developing the right method of abandoning independence is thus a high-priority goal. However, little work has been done in this area outside of a few simple approaches. To fill the gap, we compare four methods based on distance metrics between judgment sets. The methods generalize the (...) premise-based and sequential priority approaches to judgment aggregation, as well as distance-based preference aggregation. They each guarantee group consistency and implement a range of distinct functions with different properties, broadening the available tools for social choice. A central result is that only one of these methods (not previously considered in the literature) satisfies three attractive properties for all reasonable metrics. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:After the Future. The Paradoxes of Postmodernism and Contemporary Russian CultureDmitry KhaninAfter the Future. The Paradoxes of Postmodernism and Contemporary Russian Culture, by Mikhail Epstein; translated with an introduction by Anessa Miller-Pogacar; xvi & 394 pp. Amherst: University of Massachusetts Press, 1995, $55.00 cloth, $19.95 paper.Mikhail Epstein, a renowned Soviet critic—his books in Russian include Paradoxes of the New (1988) and Faith and Image: The Religious Subconscious (...) in [End Page 508] Twentieth Century Russian Culture (1994)—emigrated to the U.S. in 1988. After the Future is the first collection of his major essays (written from 1986 to 1991) in English translation. It begins with the article “New Currents in Russian Poetry: Conceptualism, Metarealism, and Presentism,” which first introduced to the Soviet reader a group of postmodernist poets, just coming out (with the advent of glasnost) from the literary underground. Other articles (“Avant-Garde Art and Religion,” “After the Future: On the New Consciousness in Literature”), though first published in Russian literary journals, were shipped to Russia from “the other shore” (to use Alexander Herzen’s description of emigre writers’ whereabouts vis-à-vis their homeland). The latest studies (“Relativistic Patterns in Totalitarian Thinking: The Linguistic Games of Soviet Ideology,” “The Origins and Meaning of Russian Postmodernism”) were not only sent from the other shore but apparently produced for the other shore. Instead of analyzing the recent Russian literary crop and emerging aesthetic sensibilities, Epstein focuses on Russian historic experience in its entirety, which he somewhat didactically clarifies for the foreign reader.Despite its shifting perspectives, After the Future features a distinctive approach toward Russian postmodernism, its bona fide subject matter. Following Jean Baudrillard, Epstein defines postmodernism as simulation (“the production of reality as a series of plausible copies”) that engenders some new hyperreality and in so doing supplants “reality itself, which then becomes irrecoverable” (p. 189). The originality of Epstein’s position lies, however, in his claim that Russia as a historic and cultural entity is a postmodernist phenomenon in its own right that simulates and masterminds reality. Epstein’s claim that postmodernism is ingrained in Russian tradition is pitted specifically against those who doubt that Russia is ready to enjoy its own postmodernist bash since (contrary to the West) it never went through prior modernist phases. To prove that Russia foreshadowed postmodernism, Epstein draws on a number of historic illustrations. He cites the forceful adoption of Christianity under Prince Vladimir in 988, Peter the Great’s building of Petersburg in the “Finnish swamp” and Prince Potemkin’s infamous make-up villages as examples of the Russian tendency to forfeit the status quo for the sake of trumped-up, ersatz realities.However, Epstein’s arguments to the effect that Russia, and not the West, is the birthplace of postmodernism are not very convincing since (in accordance with his own premise) other countries can claim such a dubious distinction as well. (“Russia is the motherland of elephants”—the Russians joke about claims by zealous patriots that all great discoveries were known in their country before they appeared elsewhere.) Elsewhere, the building of the Chinese wall and the ensuing Chinese policies of isolationism, draconian enclosures of peasant land in England that led to a speedy transition to capitalism, drastic economic and social reforms after the French Revolution, and the racist policies of the Third Reich were just as arbitrary, and yet transformative of prior realities, as any of [End Page 509] Russia’s most foolhardy experiments. Ironically, Epstein’s claim that Russia is the motherland of postmodernism harks back to the turn-of-the-century controversy as to whether it is pertinent to apply Marxist theory to rustic Russia. Lenin argued that Russia can claim Marxism as its own because all of its long-suffering history was an anticipation of Marxism and leading toward it. Epstein analogously contends that there is a special, indigenous Russian route to postmodernism, a statement that evokes similar pronouncements ingrained in Russian philosophical tradition: Epstein’s thesis that Russia is “irreal” reminds one of Peter Chaadaev’s contention that Russia does not have a history; his idea that Russia is on the threshold of a cultural synthesis with the...

Aristotle's Politics is widely recognized as one of the classics of the history of political philosophy, and like every other such masterpiece, it is a work about which there is deep division.

Combinatorial operations on sets are almost never well defined on Turing degrees, a fact so obvious that counterexamples are worth exhibiting. The case we focus on is the symmetric-difference operator; there are pairs of degrees for which the symmetric-difference operation is well defined. Some examples can be extracted from the literature, e.g. from the existence of nonzero degrees with strong minimal covers. We focus on the case of incomparable r.e. degrees for which the symmetric-difference operation is well defined.

Initial responses to questionnaires used to assess participants' understanding of informed consent for malaria vaccine trials conducted in the United States and Mali were tallied. Total scores were analyzed by age, sex, literacy (if known), and location. Ninety-two percent (92%) of answers by United States participants and 85% of answers by Malian participants were correct. Questions more likely to be answered incorrectly in Mali related to risk, and to the type of vaccine. For adult participants, independent predictors of higher scores (...) were younger age and female sex in the United States, and male sex in Mali. Scores in the United States were higher than in Mali (P = 0.005). Despite this difference participants at both sites were well informed overall. Although interpretation must be qualified because questionnaires were not intended as research tools and were not standardized among sites, these results do not support concerns about systematic low understanding among research participants in developing versus developed countries.

We use a result due to Rolin, Speissegger, and Wilkie to show that definable sets in certain o-minimal structures admit definable parameterizations by mild maps. We then use this parameterization to prove a result on the density of rational points on curves defined by restricted Pfaffian functions.

This report describes the rationale, approaches, organization, and resource development leading to a large-scale deletion bin map of the hexaploid wheat genome. Accompanying reports in this issue detail results from chromosome bin-mapping of expressed sequence tags representing genes onto the seven homoeologous chromosome groups and a global analysis of the entire mapped wheat EST data set. Among the resources developed were the first extensive public wheat EST collection. Described are protocols for sequencing, sequence processing, EST nomenclature, and the assembly of (...) ESTs into contigs. These contigs plus singletons were used for selection of distinct sequence motif unigenes. Selected ESTs were rearrayed, validated by 5′ and 3′ sequencing, and amplified for probing a series of wheat aneuploid and deletion stocks. Images and data for all Southern hybridizations were deposited in databases and were used by the coordinators for each of the seven homoeologous chromosome groups to validate the mapping results. Results from this project have established the foundation for future developments in wheat genomics. (shrink)

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

In this thesis I shall summarize and critically examine the central features of the theories of values of four contemporary moral philosophers: A.J. Ayer, C.L. Stevenson, R.M. Hare, and P.H. Nowell - Smith. I shall first look back, however, to the theory of moral philosophy of the most influential 'forefather' of this group, David Hume. Hume's theory stands as a challenge to moral philosophers who would assume that moral judgments are primarily, in some sense, acts of 'reason'. Although our four (...) contemporaries follow Hume in this, his challenge, in the form I shall indicate shortly, will provide the main theme for this thesis. (shrink)

Bernard Williams charges that the moral psychology built into R. M. Hare’s utilitarianism is incoherent in virtue of demanding a bifurcated kind of moral thinking that is possible only for agents who fail to reflect properly on their own practical decision making. I mount a qualified defence of Hare’s view by drawing on the account of the ‘reactive attitudes’ found in P. F. Strawson’s ‘Freedom and Resentment’. Against Williams, I argue that the ‘resilience’ of the reactive attitudes ensures that our (...) taking an instrumental view of our dispositions to experience guilt and compunction, as Hare calls for us to do while engaged in ‘critical’ moral thinking, will not prevent us from experiencing these feelings as people ordinarily do while we are thinking ‘intuitively’. I also consider the implications of my argument for consequentialism more generally and (briefly) Kantianism. (shrink)
