An analysis of the extension of the Hawking-Penrose singularity theorem to Riemann-Cartan U4 space-times with torsion and spin density is undertaken. The minimal coupling principle in U4 is used to formulate a new expression for the convergence condition autoparallels in Einstein-Cartan theory. The Gödel model with torsion is given as an example.

Code-based cryptography is currently the second most promising post-quantum mathematical tool for quantum-resistant algorithms. Since in 2022 the first post-quantum standard Key Encapsulation Mechanism, Kyber (a latticed-based algorithm), was selected to be established as standard, and after that the National Institute of Standards and Technology post-quantum standardization call focused in code-based cryptosystems. Three of the four candidates that remain in the fourth round are code-based algorithms. In fact, the only non-code-based algorithm (SIKE) is now considered vulnerable. Due to this landscape, (...) it is crucial to update previous results about these algorithms and their functioning. The Fujisaki-Okamoto transformation is a key part of the study of post-quantum algorithms and in this work we focus our analysis on Classic McEliece, BIKE and HQC proposals, and how they apply this transformation to obtain IND-CCA semantic security. Since after security the most important parameter in the evaluation of the algorithms is performance, we have compared the performance of the code-based algorithms of the NIST call considering the same architecture for all of them.

Integrating power dependence and gender role theories, we investigate the interactive effects of followers’ gender and leaders’ Machiavellian orientation in predicting followers’ usage of upward influence tactics. Using a sample of 156 matched leader–follower dyads, we found that followers’ gender moderated the relationship between Time 1 leaders’ Machiavellian orientation and followers’ use of upward influence tactics at Time 2. Specifically, the relationship between Time 1 leaders’ Machiavellianism and Time 2 followers’ ingratiation was significant and positive for women followers and non-significant (...) for men followers, while the relationship between Time 1 leaders’ Machiavellianism and Time 2 followers’ assertiveness was significant and positive for men followers but non-significant for women followers. These results suggest that gender plays an important role in how followers react to Machiavellian leaders. The social and ethical implications of these findings are discussed. (shrink)

This article responds to logical and social theses proposed by Professor José Medina in discussing the relativity of identity. In exploring the metaphor of family resemblance, the author argues that its causal mechanism is biological, not social; particular features of being a woman, or of belonging to a racial or ethnic group, cannot be reduced to social constructions. The article skeptically discusses the supposed importance of sex, race, and ethnicity to a person’s individual identity, and suggests that moral significance finds (...) its origin and grounding elsewhere. It concludes that no liberation can be ‘complete, or even adequate’ until it liberates the mind from ‘“scripts” rooted in the delusion of “collective identities”’. (shrink)

Many theists of a traditional bent have been bothered by the apparent tension between God's essential omnipotence and his essential moral goodness. Nelson Pike draws attention to the conflict between these two attributes in his article ‘Omnipotence and God's Ability to Sin’, and there have been many attempts to respond to it since that time. Most of these responses argue that the essential omnipotence and essential goodness of God are not logically incompatible, so that the traditional conception of God is (...) not incoherent; I think the arguments have been largely successful. However, some theists have found the typical responses to Pike less than convincing, and are tempted to surrender the claim that God has moral perfection essentially in favour of the more modest claim that God is morally perfect in the actual world though in some possible worlds God is morally defective. I argue in this paper that this fall-back position is incoherent. More accurately, I argue that a necessary being who is essentially omniscient and essentially omnipotent cannot be contingently morally perfect or contingently morally defective. Any such being is either essentially good or essentially evil. Since the latter alternative seems unattractive, I argue that theists should embrace the essential moral perfection of God. (shrink)

This paper consists of commentaries about and the reprint of an autobiographical essay authored by Italian medium Eusapia Palladino and published in 1910. The details of the essay are discussed in terms of the writings of other individuals about the life and performances of the medium. The essay conveys a view of Palladino as a person who has suffered much in life and has a mission to help scientific research into mediumship. Typical of the positive emphasis in autobiographies in general, (...) the medium did not discuss negative aspects of her performances. Due to the fact that the essay appeared during Palladino's visit to New York City in which many authors branded her as a fraud, it may be speculated that the purpose of this autobiography was to elicit sympathy from the American public. While some of the statements that Palladino made about phenomena are consistent with the statements of other authors who have written about her, there are several statements that show alternate or incomplete versions of particular events in her life. The differences suggests that Palladino's essay and other discussions about the medium's life are not reliable when it comes to specific details and to biographical accuracy. (shrink)

I first sketch an account of humility as a character trait in which we are unimpressed with our good, envied, or admired features, achievements, etc., where these lack significant salience for our image of ourselves, because of the greater prominence of our limitations and flaws. I situate this view among several other recent conceptions of humility (also called modesty), dividing them between the inward-directed and outward-directed, distinguish mine from them, pose problems for each alternative account, and show how my understanding (...) of humility captures truths present but exaggerated in several of them. Responding to some problems for my view, including what I call “Driver’s Paradox”(i.e., the strangeness of someone’s proclaiming ‘I’m humble!’), I suggest that some over-ambitious claims about our moral responsibilities may indicate a lack of proper humility. I discuss the relationship of the character trait of humility both to what humiliates and to what humbles, concluding with consideration of the background assumptions against which, and the circumstances in which, humility may reasonably be classified as a moral virtue.

In the seventh and most recent edition of their classic book, Principles of Biomedical Ethics, Tom Beauchamp and James Childress define a virtue as a character trait that is “socially valuable and reliably present” and a moral virtue as such a trait that is also both “dispositional” and “morally valuable”. The virtues that they single out as “focal” within biomedical ethics are compassion, discernment, trustworthiness, integrity, and conscientiousness. Not all is well in their treatment of virtue. Beauchamp and Childress seem (...) to worry that an ethical theory in which virtues are fundamental will neglect duties, rights, and societal needs. Further, they insist that there is no reason to think that, within ethical theory, one family of ethical concepts is the most important, nor that one theoretical approach is correct, or even superior to others. I will try to show, that there are strong reasons to see language, concepts, and matters of virtue as fundamental within normative ethical theory, both generally and in such specialized subareas as medical ethics. These reasons reveal themselves when we analyze concepts at the core of the alternative approaches to theorizing ethics that Beauchamp and Childress identify. (shrink)

Efforts to promote responsible conduct of research (RCR) should take into consideration how scientists already conceptualize the relationship between ethics and science. In this study, we investigated how scientists relate ethics and science by analyzing the values expressed in interviews with fifteen science faculty members at a large midwestern university. We identified the values the scientists appealed to when discussing research ethics, how explicitly they related their values to ethics, and the relationships between the values they appealed to. We found (...) that the scientists in our study appealed to epistemic and ethical values with about the same frequency, and much more often than any other type of value. We also found that they explicitly associated epistemic values with ethical values. Participants were more likely to describe epistemic and ethical values as supporting each other, rather than trading off with each other. This suggests that many scientists already have a sophisticated understanding of the relationship between ethics and science, which may be an important resource for RCR training interventions.

The paper defends the thesis that for S to V intentionally is for S to V as (in the way) S intended to. For the normal agent the relevant sort of intention is an intention that one's intention to V generate an instance of one's V-ing along some (usually dimly-conceived) productive path. Such an account allows us to say some actions are intentional to a greater or lesser extent (a desirable option for certain cases of wayward causal chains), preserves the (...) intuitive link between intention and intentionally, and supports the common sense view that the concept of intending is more basic than those of acting with an intention and of acting intentionally. The remainder of the paper responds to certain apparent counter-examples offered by Audi, Harman, and Bratman. In the course of this, I discuss connections between intending to V and hoping to V, and I argue that one can intend to do what one doesn't expect to do, and that one always intends what one attempts.

Drawing chiefly on recent sources, in Part One I sketch an untraditional way of articulating what I claim to be central elements of traditional Catholic morality, treating it as based in virtues, focused on the recipients (“patients”) of our attention and concern, and centered in certain person-to-person role-relationships. I show the limited and derivative places of “natural law,” and therefore of sin, within that framework. I also sketch out some possible implications for medical ethics of this approach to moral theory, (...) and briefly contrast these with the influential alternative offered by the “principlism” of Beauchamp and Childress. In Part Two, I turn to a Catholic understanding of the nature and meaning of human suffering, drawing especially on writings and addresses of the late Pope John Paul II. He reminds us that physical and mental suffering can provide an opportunity to share in Christ's salvific sacrifice, better to see the nature of our earthly vocation, and to reflect on the dependence that inheres in human existence. At various places, and especially in my conclusion, I suggest a few ways in which this can inform bioethical reflection on morally appropriate responses to those afflicted by physical or mental pain, disability, mental impairment, disease, illness, and poor health prospects. My general point is that mercy must be informed by appreciation of the person's dignity and status. Throughout, my approach is philosophical rather than theological. (shrink)

This essay rebuts Gary Seay's efforts to show that committing euthanasia need not conflict with a physician's professional duties. First, I try to show how his misunderstanding of the correlativity of rights and duties and his discussion of the foundation of moral rights undermine his case. Second, I show aspects of physicians' professional duties that clash with euthanasia, and that attempts to avoid this clash lead to absurdities. For professional duties are best understood as deriving from professional virtues and the (...) commitments and purposes with which the professional as such ought to act, and there is no plausible way in which her death can be seen as advancing the patient's medical welfare. Third, I argue against Prof. Seay's assumption that apparent conflicts among professional duties must be resolved through "balancing" and argue that, while the physician's duty to extend life is continuous with her duty to protect health, any duty to relieve pain is subordinate to these. Finally, I show that what is morally determinative here, as throughout the moral life, is the agent's intention and that Prof. Seay's implicitly preferred consequentialism threatens not only to distort moral thinking but would altogether undermine the medical (and any other) profession and its internal ethics.

Morality and religion: intimately wed, violently opposed, or something else? Discussion of this issue appears in pop culture, the academy, and the media―often generating radically opposed views. At one end of the spectrum are those who think that unless God exists, ethics is unfounded and the moral life is unmotivated. At the other end are those who think that religious belief is unnecessary for―and even a threat to―ethical knowledge and the moral life. -/- This volume provides an accessible, charitable discussion (...) that represents a range of views along this spectrum. The book begins with a lively debate between Paul Kurtz and William Lane Craig on the question, Is goodness without God good enough? Kurtz defends the affirmative position and Craig the negative. Following the debate are new essays by prominent scholars. These essays comment on the debate and advance the broader discussion of religion and morality. The book closes with final responses from Kurtz and Craig. (shrink)

Prof. Alberto Urquidez, in an important recent article that appears in different form in his book, Redefining Racism, offers an informed, sustained, careful, multi-pronged, and sometimes original critique of the volitional analysis of racism, which I have proposed in a series of articles over the past two dozen years. Here I expand and improve VAR’s analysis of paternalistic racists and their beliefs, clarify its ‘infection’-model’s explanation of racism’s spread and variety, and lay out what it is for something to be (...) ‘characteristically’ racist, an understanding that I then use to offer a unified account of the way in which both certain physical objects and certain abstract objects can properly be called racist. Identifying and engaging some presuppositions behind Urquidez’s social, political, and moral criticisms of VAR, I respond to complaints from him and others, showing that VAR’s content is neither politically conservative nor dependent on religious doctrine, and point out that race theory would in fact profit from taking more seriously and internalizing the Christian morality of most African-Americans.

Alternative splicing (AS) is a widespread mechanism with an important role in increasing transcriptome and proteome diversity by generating multiple different products from the same gene. Evolutionary studies of AS have focused primarily on the conservation of alternatively spliced sequences or of the AS pattern of those sequences itself. Less is known about the evolution of the regulation of AS, but several studies, working from different perspectives, have recently made significant progress. Here, we categorize the different levels of AS evolution, (...) and summarize the studies on evolution of AS regulation, which point to a high level of evolutionary conservation of the regulation of AS events conserved between related species. This suggests that the quantitative regulation of AS is an intrinsic part of AS function. We discuss the potential role of changes in developmental regulation of AS as an additional layer in complex gene regulatory networks and in the emergence of genetic novelties. (shrink)

Do cultural models facilitate particular ways of perceiving interactions in nature? We explore variability in folkecological principles of reasoning about interspecies interactions. In two studies, Indigenous Panamanian Ngöbe and U.S. participants interpreted an illustrated, wordless nonfiction book about the hunting relationship between a coyote and badger. Across both studies, the majority of Ngöbe interpreted the hunting relationship as cooperative and the majority of U.S. participants as competitive. Study 2 showed that this pattern may reflect different beliefs about, and perhaps different (...) awareness of, plausible interspecies interactions. Further probes suggest that these models of ecological interaction correlate with recognition of social agency in nonhuman animals. We interpret our results in terms of cultural models of nature and nonhuman agency. (shrink)

Tommie Shelby has offered an influential, carefully stated, and well-argued set of objections to any volitional analysis of racism (VAR) as consisting centrally in certain forms of race-based disregard. Here I hope to defend aspects of VAR by analyzing, evaluating, and sometimes countering several of his major contentions, which have stood unchallenged in the literature over more than two decades. First, I sketch and respond to his Methodological objection to VAR, which criticizes VAR's reliance on language and linguistic intuitions; then (...) to a Psychological objection, which suggests that VAR implausibly distances an agent's intentions from her beliefs; and, finally, to a Psychopathological objection, which holds that VAR requires treating as unproblematic some psychological states better seen as aberrant. The following section treats three subtle counterexamples Shelby uses to challenge VAR's core contentions about what's necessary and what's sufficient for racism. I close with some gestures toward what I see as a promising approach, very different from his, to studying these topics. (shrink)

Design arguments make a case for the existence of God based on examples of apparent design or purposiveness in the natural world. Current versions of the argument proceed, not in terms of analogies between the universe and human artifacts, but as inductive arguments to the best explanation of the data. Theism is offered as the simplest hypothesis that can explain facts such as the mathematical elegance and intelligibility of the laws of the nature. The design argument has recently received new (...) life from discoveries regarding the fine-tuning required for any universe capable of sustaining life. (shrink)

Contemporary discourse is littered with nasty and derailed disagreements. In this paper we hope to help clean things up. We diagnose two patterns of thought that often plague and exacerbate controversy. We illustrate these patterns and show that each involves both a logical mistake and a failure of intellectual charity. We also draw upon recent work in social psychology to shed light on why we tend to fall into these patterns of thought. We conclude by suggesting how the intellectual virtues (...) can militate against these fallacies, focusing on the virtues of charity and humility. (shrink)
