Attentional control theory (ACT) was proposed to account for trait anxiety’s effects on cognitive performance. According to ACT, impaired processing efficiency in high anxiety is mediated through inefficient executive processes that are needed for effective attentional control. Here we review the central assumptions and predictions of ACT within the context of more recent empirical evidence from neuroimaging studies. We then attempt to provide an account of ACT within a framework of the relevant cognitive processes and their associated neural mechanisms and (...) networks, particularly the fronto-parietal, cingular-opercula, and default mode networks. Future research directions, including whether a neuroscience-informed model of ACT can provide a platform for novel neurocognitive intervention for anxiety, are also discussed. (shrink)

Presented in six principal analytic chapters with supporting appendices, this book explores the role of Islam in precipitating Europe's twelfth century commercial renaissance. Employing the classic analytic techniques of economics, Gene Heck determines that medieval Europe's feudal interregnum was largely caused by indigenous governmental business regulation and not by shifts in international trade patterns. He then proceeds by demonstrating how Islamic economic precepts provided the ideological rationales that empowered medieval Europe to escape its three-centuries-long experiment in "Dark Age economics" (...) ― in the process, providing the West with its archetypic tools of capitalism. While treatises such as Maxime Rodinson's excellent book, Islam and Capitalism, document the capitalistic nature of the Islamic economic system, in applying modern economic method to medieval orientalist historiography, this work is unique in capturing both the evolution and the impact of the system's role in forging medieval history.

Restructured health care reimbursement systems and new requirements for nonprofit hospitals are transforming the U.S. health system, creating opportunities for enhanced integration of public health and health care goals. This article explores the role of public health practitioners and lawyers in this moment of transformation. We argue that the population perspective and structural strategies that characterize public health can add value to the health care system but could get lost in translation as changes to tax requirements and payment systems are (...) rapidly implemented. We urge public health leaders to take a more active role in hospital assessments of community health needs and evaluation of the patient outcomes for which providers are accountable. (shrink)

The Streptococcus pyogenes CRISPR‐Cas system has gained widespread application as a genome editing and gene regulation tool as simultaneous cellular delivery of the Cas9 protein and guide RNAs enables recognition of specific DNA sequences. The recent discovery that Cas9 can also bind and cleave RNA in an RNA‐programmable manner indicates the potential utility of this system as a universal nucleic acid‐recognition technology. RNA‐targeted Cas9 (RCas9) could allow identification and manipulation of RNA substrates in live cells, empowering the study of (...) cellular gene expression, and could ultimately spawn patient‐ and disease‐specific diagnostic and therapeutic tools. Here we describe the development of RCas9 and compare it to previous methods for RNA targeting, including engineered RNA‐binding proteins and other types of CRISPR‐Cas systems. We discuss potential uses ranging from live imaging of transcriptional dynamics to patient‐specific therapies and applications in synthetic biology. (shrink)

Before September 11, 2001, a mass-casualty terrorist attack on American soil was generally considered a remote possibility.

Despite widespread agreement that it would be ethical to use somatic cell gene therapy to correct serious diseases, there is still uneasiness on the part of the public about this procedure. The basis for this concern lies less with the procedure's clinical risks than with fear that genetic engineering could lead to changes in human nature. Legitimate concerns about the potential for misuse of gene transfer technology justify drawing a moral line that includes corrective germline therapy but excludes (...) enhancement interventions in both somatic and germline contexts.

Bertolt Brecht and Theodor W. Adorno stand for opposing modes and stances within an artistic modernism oriented toward radical social transformation. In his 1962 essay ‘Commitment’, Adorno advanced a biting critique of Brecht’s work and artistic position. Adorno’s arguments have often been dismissed but, surprisingly, are seldom closely engaged with. This paper assesses these two approaches that have been so central to twentieth-century debates in aesthetics: Brecht’s dialectical realism and Adorno’s sublime or dissonant modernism. It provides what still has been (...) missing: a close reading and immanent critique of Adorno’s case against Brecht. And it clarifies one methodological blind spot of Adorno’s formalist conceptualisation of autonomy: he fails to provide the detailed analysis of context that his own dialectical method immanently calls for. The paper shows how and why Brecht’s dialectical realism holds up under Adorno’s attack, and draws conclusions for contemporary artistic practice. (shrink)

Joseph Beuys’ installation Plight forcefully avows of the Nazi genocide by means of negative presentation. The work culminates a collective artistic investigation of negative sculptural strategies for representing traumatic history, opened by the Nouveaux Réalistes under the impact of Alain Resnais’ documentary film Nuit et Brouillard. This article outlines this history and analyzes Plight in the context of the ‘after Auschwitz’ crisis of representation and traditional culture theorized by Theodor W. Adorno. For Adorno, Auschwitz demonstrated threats to autonomous subjectivity posed (...) by tendencies unfolding within the global social process of modernity itself. Reflecting on the fate of music, poetry and literature under these conditions, Adorno advocated a hermetic art of silence and dissonance, as exemplified by Paul Celan and above all Samuel Beckett. This article shows that in the visual arts, too, the genocidal violence of World War II was confronted with analogous strategies of indirection. In Plight, Beuys would successfully synthesize John Cage’s symbolic demolitions of traditional music and the investigations of negative presentation carried out in sculpture by Arman and Daniel Spoerri.

types of application of genetic engineering for the insertion of genes into humans. The scientific requirements and the ethical issues associated with each type are discussed. Somatic cell gene therapy is technically the simplest and ethically the least controversial. The first clinical trials will probably be undertaken within the next year. Germ line gene therapy will require major advances in our present knowledge and it raises ethical issues that are now being debated. In order to provide guidelines for (...) determining when germ line gene therapy would be ethical, the author presents three criteria which should be satisfied prior to the time that a clinical protocol is attempted in humans. Enhancement genetic engineering presents significant, and troubling, ethical concerns. Except where this type of therapy can be justified on the grounds of preventive medicine, enhancement engineering should not be performed. The fourth type, eugenic genetic engineering, is impossible at present and will probably remain so for the foreseeable future, despite the widespread media attention it has received.

Darwinism presents a paradox. It discredits the notion that one’s life has any intrinsic meaning, yet it predicts that we are designed by Darwinian natural selection to generally insist that it must—and so necessarily designed to misunderstand and doubt Darwinism. The implications of this paradox are explored here, including the question of where then does the Darwinist find meaning in life? The main source, it is proposed, is from cognitive domains for meaning inherited from sentient ancestors—domains that reveal our evolved (...) human nature as the fool that it is: given to distractions and delusions of many kinds, designed by natural selection primarily for one essential purpose—to allay our instinctual fear of failed legacy, rooted in our uniquely human awareness that we are not immortal. Darwinism, however, also teaches that genuine legacy is a fate enjoyed only by individual genes. Accordingly, as argued here, those genes with the grandest legacy—and hence rampant within us—are of two types: “legacy-drive” genes delude us into thinking that the legacy can be individually and personally ours; and “leisure-drive” genes distract us from the agonizing truth that it can never be. The most rudimental delusion of legacy is the perception of offspring as vehicles for memetic legacy—the transmission of resident memes from one’s mind to the minds and behaviors of offspring— thus also ensuring genetic legacy: the transmission of resident genes, including importantly, genes inherited from ancestors that influence both legacy and leisure drives. Today, legacyand leisure-drive genes reveal their phenotypes across a wide range of human affairs, and together with the phenotypes of survival- and sex-drive genes, they provide a foundation for a novel view of the Darwinian roots of cultural evolution.

That holobionts are units of selection squares poorly with the observation that microbes are often recruited from the environment, not passed down vertically from parent to offspring, as required for collective reproduction. The taxonomic makeup of a holobiont’s microbial community may vary over its lifetime and differ from that of conspecifics. In contrast, biochemical functions of the microbiota and contributions to host biology are more conserved, with taxonomically variable but functionally similar microbes recurring across generations and hosts. To save what (...) is of interest in holobiont thinking, we propose casting metabolic and developmental interaction patterns, rather than the taxa responsible for them, as units of selection. Such units need not directly reproduce or form parent-offspring lineages: their prior existence has created the conditions under which taxa with the genes necessary to carry out their steps have evolved in large numbers. These taxa or genes will reconstruct the original interaction patterns when favorable conditions occur. Interaction patterns will vary in ways that affect the likelihood of and circumstances under which such reconstruction occurs. Thus, they vary in fitness, and evolution by natural selection will occur at this level. It is on the persistence, reconstruction, and spread of such interaction patterns that students of holobiosis should concentrate, we suggest. This model also addresses other multi-species collectively beneficial interactions, such as biofilms or biogeochemical cycles maintaining all life. (shrink)

SummaryThis paper defends the philosophical importance of analyticity against the influential objections raised by W. V. Quine. It characterizes analyticity in a way that is nonepistemic, avoids Quine's objections and fits his general strictures, and explains the epistemological importance of analyticity. It also explains why even proponents of Quine's naturalized epistemology should value the epistemological importance of analyticity, in connection with questions about the correctness of their epistemic principles. Given these considerations, this paper may be regarded as having rescued analyticity (...) from the throes of suspicion and myth, as set by “Two Dogmas of Empiricism.”. (shrink)

Recent obituaries for traditional non-naturalistic approaches to rationality are not just premature but demonstrably self-defeating. One such prominent obituary appears in the writings of W. V. Quine, whose pessimism about traditional epistemology stems from his scientism, the view that the natural sciences have a monopoly on legitimate theoretical explanation. Quine also offers an obituary for the a priori constraints on rationality found in “first philosophy”, resting on his rejection of the “pernicious mentalism” of semantic theories of meaning. Quine’s pronouncements of (...) the death of traditional conceptions of rationality in epistemology and in the theory of meaning are, we contend, but misguided wishes for their death, wishes that face severe problems of self-defeat. In addition, Quine’s naturalistic epistemology is subject to damaging skeptical worries, the force of which one cannot escape by ignoring them. A non-naturalistic approach to rationality is here to stay, whether friends of Quine’s naturalism like it or not. Any sweeping claim that non-naturalistic accounts of rationality are dead will face insurmountable obstacles from unavoidable questions about its own rational justification. Such questions will keep non-naturalistic epistemology and first philosophy alive forever, or at least as long as philosophers endure. (shrink)

Our understanding of what microbes are and how they evolve has undergone many radical shifts since the late nineteenth century, when many still believed that bacteria could be spontaneously generated and most thought microbial “species” (if any) to be unstable and interchangeable in form and function (pleomorphic). By the late twentieth century, an ontology based on single cells and definable species with predictable properties, evolving like species of animals or plants, was widely accepted. Now, however, genomic and metagenomic data show (...) that lateral gene transfer compromises this picture of stability and predictability, and refocuses our attention on multilineage communities. Treating such communities as unstable but identifiable evolving “individuals” makes us again pleomorphists, of a sort. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Thomas Aquinas and the Crisis of Christology ed. by Michael A. Dauphinais, Andrew Hofer, O.P., and Roger W. NuttJ. David MoserThomas Aquinas and the Crisis of Christology edited by Michael A. Dauphinais, Andrew Hofer, O.P., and Roger W. Nutt (Ave Maria, FL: Sapientia Press, 2021), ix + 422 pp.This volume is a collection of papers presented at the "Thomas Aquinas and the Crisis of Christology" conference at the (...) Aquinas Center of Ave Maria University in Ave Maria, Florida, in February 2020. Dozens of papers were presented at the conference; this volume contains many of the plenary papers and the two keynote addresses given by Bruce Marshall and Thomas Joseph White, O.P.The title, especially the term "crisis," has multiple meanings in the essays. On the one hand, some of them address the crisis in contemporary Christology. For example, Michael Dauphinais draws on Aquinas's theology of participation to pose what he sees as a better alternative to Richard Rohr's The Universal Christ. As Dauphinais shows, Rohr's popular Christology conflates Incarnation and creation as one and the same reality. Through careful exegesis of Aquinas's Commentary on John, Dauphinais argues that the Incarnation must be distinct as a unique act of God, and thus decidedly not the same as creation (253). On the other hand, as J. Augustine DiNoia observes in his foreword, the term "crisis" comes from the Greek krisis, or "judgment" (ix). Christ's judgment of all human beings emerges as a persistent theme in the volume. So Andrew Hofer's introduction explores Aquinas's teaching on Christ's judgment of teachers of the faith, noting the implications for theologians who hold the office of teacher. Marshall's and Daria Spezzano's essays are powerful accounts of Christ's role as judge. Both diagnose contemporary crises of faith over which we will be judged and remind us that the Lord Jesus judges to save those who love him. These essays read almost like sermons, and they deserve careful attention when [End Page 1435] Christ's judgment seems irrelevant in an age when God can only be thought to be winsome and nice.Some of the essays contribute to ongoing Thomistic scholarly debates. The vexed question of how to understand the esse secundarium in article 4 of Aquinas's De unione verbi incarnati receives two essays: one by Roger Nutt and the other by Steven A. Long. Nutt argues that Aquinas did not reverse his teaching on the single esse of Christ in the De unione. He observes that Aquinas uses the terms principale and secundarium to manifest "the ultimate unity of composite realities," and thus secundarium esse is not "second esse" in the order of being (87). Like Nutt, Long argues that Aquinas is consistent in his position on Christ's singular esse. He invokes a wide array of interpretive and metaphysical arguments in a mere nine pages. Though they do not resolve the problem (at least in my view: how could an esse distinct from another esse be numerically the same esse, as they would have to be for Christ to have one esse?), they are useful contributions to the ongoing interpretation of Aquinas on this point.Similarly, Christ's human knowledge in Aquinas's theology and Catholic doctrine gets two essays. White expands on prior work on this topic and argues that Christ maintained consciousness of his filial identity prior to the resurrection. As usual, he does careful work deploying the insights of Catholic doctrine in conversation with biblical studies. Simon Francis Gaine expands on his argument in Did the Saviour See the Father? Christ, Salvation and the Vision of God by arguing that a divine person does not need to have the beatific vision to be incarnate. He contrasts metaphysical necessity with soteriological necessity; Christ needed to have the beatific vision to give it to us, but he did not need it as a necessary consequence of being incarnate. It would be interesting to see Gaine and other Thomists interact with John Duns Scotus's argument that Christ could be incarnate without the beatific vision, or highest possible grace (Ordinatio III, d. 13). Scotus, in my... (shrink)

A remarkable event occurred at the December 3, 2004, meeting of the U. S. President’s Council on Bioethics. Council member William Hurlbut, a physician and Consulting Professor in the Program in Human Biology at Stanford University, formally unveiled a proposal that he claimed would solve the ethical problems surrounding the extraction of stem cells from human embryos. The proposal would involve the creation of genetically defective embryos that “never rise to the level of integrated organismal existence essential to be designated (...) human life with potential,” and therefore could be used as morally acceptable sources of stem cells for research and therapy. The aim of this essay is to show that Hurlbut’s proposal does not solve the ethical problems associated with human embryonic stem cell research. Two major reasons are presented. First, the proposal, which involves modification of a somatic cell nucleus, suffers from an ethical problem that is common to all types of human genetic engineering: since the procedure is not foolproof, there will be failures. In the case of the procedure Hurlbut proposes, some normal (albeit cloned) embryos will be produced. Second, the embryo engineered in the manner described is, at least in the early stages of its development, fully human despite its genetic defect. This essay also will show how a reasonable person might mistakenly view the proposal as legitimate if he or she makes the error of conflating genetic determinism with Aristotelian teleology. Finally, it will argue that ethical clarity can be achieved by seeing the embryo as a holistic entity possessing emergent properties that cannot simply be spelled out by genes. (shrink)

In this new post-genomic age of medicine and biomedical technology, there will be novel approaches to understanding disease, and to finding drugs and cures for diseases. Hundreds of new “disease genes” thought to be the causative agents of various genetic maladies will be identified and added to the list of hundreds of such genes already identified. Based on this knowledge, many new genetic tests will be developed and used in genetic screening programs. Genetic screening is the foundation upon which reproductive (...) technologies such as pre-natal diagnosis (PND) and preimplantation genetic diagnosis (PGD) are based. Genetic information arising from the human genome may also be used in attempts to redesign the human genetic inheritance by engineering the human germline (germline engineering). In each of these technologies—PND, PGD, and germline engineering—there are serious ethical and social concerns. Moreover, all three are eugenic in nature because they strive to control which genes are passed down to future generations. The goals of this article are threefold: 1) to introduce the science behind the three technologies; 2) to give a brief overview of eugenics in the past century and show how these genetic technologies are eugenic; and 3) to present a vision of social justice that rejects the genetic determinism upon which eugenics is based and embraces a holistic, ecological view of nature and humanity.

This essay moves along broad lines from molecular biology to evolutionary biology and ecology to theology. Its objectives are to: 1) present some recent scientific findings in the emerging field of epigenetics that indicate that it is “the genome in context,” not genes per se, that are important in biological development and evolution; 2) show that this weakens the gene-centric neo-Darwinist explanation of evolution which, in fact, shares a certain preformationist orientation with intelligent design theory; 3) argue that the (...) evidence against a gene-centric view in no way negates Darwin’s central idea of “descent with modification”; 4) argue that an embrace of the evolutionary story, with all of its contingency and apparent lack of directionality, is not only consistent with Christianity, but actually resonates with the notion of the self-emptying love of God in Jesus Christ; and finally 5) suggest that we are called through an ecological imperative to embrace our evolutionary story, to listen to our “genetic coding,” and to reclaim our grounding as a species in the natural world. Corrigendum (published in later issue of journal): There was an error in the paragraph describing the mode of action of the small temporally-expressed RNAs (stRNAs) lin-4 and let-7 from Caenorhabditis elegans. Instead of reading "These two stRNAs act by binding to the tails of their target messenger RNAs (mRNAs); this results in destruction of the target and an overall drop in the level of production of protein from agouti mRNA" [note that agouti mRNA is not a target of these stRNAs], the sentence should have read, "These two stRNAs act by binding to the tails of target messenger RNAs (mRNAs); this leads to inhibition of translation of the mRNAs into protein and a consequent drop in the levels of the corresponding target protein.".
