D‐amino acids are being recognized as functionally important molecules in mammals. We recently identified endogenous D‐cysteine in mammalian brain. D‐cysteine is present in neonatal brain in substantial amounts (mM) and decreases with postnatal development. D‐cysteine binds to MARCKS and a host of proteins implicated in cell division and neurodevelopmental disorders. D‐cysteine decreases phosphorylation of MARCKS in neural progenitor cells (NPCs) affecting its translocation. D‐cysteine controls NPC proliferation by inhibiting AKT signaling. Exogenous D‐cysteine inhibits AKT phosphorylation at Thr 308 and Ser (...) 473 in NPCs. D‐cysteine treatment of NPCs led to 50% reduction in phosphorylation of Foxo1 at Ser 256 and Foxo3a at Ser 253. We hypothesize that in the developing brain endogenous D‐cysteine is as a physiologic regulator of NPC proliferation by inhibiting AKT signaling mediated by Foxo1 and Foxo3a. Endogenous D‐cysteine may regulate mammalian neurodevelopment with roles in schizophrenia and Alzheimer's disease (AD). (shrink)

The human community faces today the most serious challenges ever to have confronted the planet in the areas of health, environment, and security. Science and technology are essential for responding to these challenges. More is needed, however, because science is not equipped to deal adequately with the values dimensions and the political issues that accompany the challenges. For an adequate response, there must be cooperative effort by scientists and statespersons, informed for moral leadership by the religious wisdom that is available. (...) The religious communities can provide this spiritual dimension, thereby fulfilling their traditional role, but it will require their coming to terms with the character of the scientific and technological base of contemporary culture. The paper lays the conceptual groundwork for understanding these issues. (shrink)

A more complete understanding of the biocultural evolutionary origins of the concept of ought as developed by David Hume and G. E. Moore may lower the philosophical barrier between is and ought and provide new insights about the separations between the domains of religion and science. If this conjecture is correct, the resulting wisdom will help transcend a major source of irony that Philip Hefner has so aptly identified in his essay.

This essay addresses a series of eight questions about what religion can do for science. It explores the secular role of religion in contemporary science and the need for greater synthesis between science and religion. It concludes that, for survival in the twenty‐first century, religion cannot exist without acknowledging and using the enormous information pool of science, and science can no longer shun or ignore religion. Humankind will always need the large, synthetic explanations that religion provides of why we are (...) here and what we ought to do and believe. The world needs to mark this new millennium with a sense of respect, cooperation, and even synthesis between science and religion. (shrink)

The evolution of human diet is the product of both biological and cultural adaptations to various plants and animals in the environment. This paper develops a new theory for the evolution of cuisine practices which attempts to account for how food processing provided a critical link in enhancing the nutrient balance of major domesticated plants.

In meeting the challenges of fashioning a new health care system, South Africa stands poised to contribute to a better future for its own citizens and the subcontinent.

Teachers and Texts in the Ancient World presents a comprehensive and accessible survey of religious and philosophical teaching and classroom practices in the ancient world. Snyder synthesizes a wide range of ancient evidence and modern scholarship to address such questions as how the literary practices of Jews and Christians compared to the literary practices of the philosophical schools and whether Christians were particularly noteworthy for their attachment to scripture.

Fossil fuel divestment movements have gained momentum since 2011, aimed at ending fossil fuel use and a move toward a cleaner, affordable, and sustainable energy system, for business and society. The present study investigates the direct impact of fossil fuel divestment announcements on stock prices of firms listed on the United States' stock exchanges. Using an event study and guided by the United Nation's sustainable development goals (SDGs), we test the effects of 116 divestments announcements between 2014 and 2019 on (...) 51 publicly traded fossil fuel companies. Our results suggest that there is a negative effect of these announcements on fossil fuel firm stock prices. Also, we find that the type of fossil fuel firm (coal or oil and gas), the type of divestment (partial, coal only, or full), the timing of the announcement, and the size of the divesting investor have some explanatory power in relation to the (cumulative) abnormal returns following the divestment announcements. While the negative impact on stock prices is not surprising, the reaction from the divested firms after such large divestitures is not consistent with what may be expected, given past reactions to divestitures seeking to achieve different social goals. Given the SDGs, it seems clear why investors are divesting themselves from fossil fuel firms, but why has the reaction to the 116 divestments led to very little change in the way these publicly traded fossil fuel firms do business given their direct and growing impacts on society? We conclude the study with some suggestions for future research. (shrink)

Prompted by a 2019 essay by Jonathan Moreno in the Hastings Center Report, the Center's board of directors undertook a careful examination of the name of its preeiminent award, the Henry Knowles Beecher Award, which has been given to twenty‐nine individuals who have made lifetime contributions to bioethics. citing new research that revealed that Beecher's earlier experimentation on drugs had involved nonconsenting adults, Moreno urged the Center to reevaluate honoring Beecher through this award. After reviewing the relevant published evidence and (...) holding extensive discussions, the board decided to rename the award. We also took the opportunity to reframe the award to emphasize quality of scholarship and impact on thinking, practice, and policy rather than lifetime achievement. The new name—the Founders’ Award of The Hastings Center—reflects our desire to honor not only the Center's cofounders, Daniel Callahan and Willard Gaylin, but also others who helped found the field of bioethics. With great pride, the Center has announced that Patricia King of the Georgetown University Law Center is the 2021 recipient of the Founders’ Award. A distinguished civil rights lawyer, King was instrumental in ensuring justice as one of the three principles of The Belmont Report. (shrink)

This book is the first philosophy of religion anthology to offer a broad survey of classical and contemporary, Western and non-Western readings. This book includes the standard topics for traditional philosophy of religion courses, as well as ample material for courses incorporating a more global approach. The text also provides abundant pedagogical support for both instructors and stiudents new to the study of non-Western philosophies of religion. It includes such features as an introductory chapter on world religions, introductions to each (...) reading, study questions, glossary, pronunciation guide, and suggested readings. --. (shrink)

Both unipolar and bipolar depression have been linked with impairments in executive functioning. In particular, mood symptom severity is associated with differences in common EF, a latent measure of general EF abilities. The relationship between mood disorders and EF is particularly salient in adolescence and young adulthood when the ongoing development of EF intersects with a higher risk of mood disorder onset. However, it remains unclear if common EF impairments have associations with specific symptom dimensions of mood pathology such as (...) blunted positive affect, mood instability, or physiological arousal, or if differences in common EF more broadly relate to what is shared across various symptom domains, such as general negative affect or distress. To address this question, bifactor models can be applied to simultaneously examine the shared and unique contributions of particular mood symptom dimensions. However, no studies to our knowledge have examined bifactor models of mood symptoms in relation to measures of common EF. This study examined associations between common EF and general vs. specific symptom dimensions using structural equation modeling in adolescents and young adults with varying severity of mood symptoms. A General Depression factor capturing shared variance across symptoms statistically predicted lower Common EF. Additionally, a factor specific to physiological arousal was associated with lower Common EF. Anhedonia-specific and Mania-specific factors were not significantly related to Common EF. Altogether, these results indicate that deficits in common EF are driven by, or reflect, general features of mood pathology that are shared across symptom dimensions but are also specifically associated with physiological arousal.

Comparing cognitive functions between humans and nonhuman primates is helpful for understanding human tool use. We comment on the latest insights from comparative research on executive control functions. Based on our own work, we discuss how even a mental function in which non-human primates outperform humans might have played a key role in the development of tool use.

According to many accounts of faith—where faith is thought of as something psychological, e.g., an attitude, state, or trait—one cannot have faith without belief of the relevant propositions. According to other accounts of faith, one can have faith without belief of the relevant propositions. Call the first sort of account doxasticism since it insists that faith requires belief; call the second nondoxasticism since it allows faith without belief. The New Testament may seem to favor doxasticism over nondoxasticism. For it may (...) seem that, according to the NT authors, one can have faith in God, as providential, or faith that Jesus is the Messiah, or be a person of Christian faith, and the like only if one believes the relevant propositions. In this essay, I propose to assess this tension, as it pertains to the Gospel of Mark. The upshot of my assessment is that, while it may well appear that, according to Mark, one can have faith only if one believes the relevant propositions, appearances are deceiving. Mark said no such thing. Rather, what Mark said—by way of story—about faith fits nondoxasticism at least as well as doxasticism, arguably better. More importantly, the account of faith that emerges from Mark is that faith consists in resilience in the face of challenges to living in light of the overall positive stance to the object of faith, where that stance consists in certain conative, cognitive, and behavioral-dispositional elements.
