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.

Adolescence is an important developmental period marked by a transition from primarily parental-controlled eating to self-directed and peer-influenced eating. During this period, adolescents gain autonomy over their individual food choices and eating behavior in general. While parent-feeding practices have been shown to influence eating behaviors in children, little is known about how these relationships track across adolescent development as autonomy expands. The purpose of this qualitative study was to identify factors that impact food decisions and eating autonomy among adolescents. Using (...) the food choice process model as a guide, four focus groups were conducted with 34 adolescents. Focus group discussion was semi-structured, asking teens about influences on their food choices across different food environments, their involvement with food purchasing and preparation, and perceived control over food their choices. Focus group transcripts were analyzed using deductive and inductive code creation and thematic analysis. This study found six leading influences on adolescents' food choices and identified additional factors with prominence within specific environmental contexts. This study distinguished a broader spectrum of factors influencing adolescent food choice that extend beyond “convenience” and “taste” which have previously been identified as significant contributors. The degree of control that teens reported differed by eating location, occasion, and social context. Finally, adolescents demonstrated various levels of engagement in behaviors related to their eating autonomy. Identifying the emergent themes related to adolescent autonomy was the first step toward the goal of developing a scale to evaluate adolescent eating autonomy. (shrink)

Springer. We find in contemporary culture starkly contrasting estimates of the value of faith. On the one hand, for many people, faith is a virtue or positive human value, something associated with understanding, hope, and love, something to be inculcated, maintained, and cherished. On the other hand, for many people, faith is a vice, something associated with dogmatism, arrogance, and close-mindedness, something to be avoided at all costs. The papers included in this special (double) issue on approaches to faith explore (...) questions about faith in a variety of settings through a diverse range of examples, both secular and religious. The attempt to deepen our understanding of faith in the context of ordinary human relationships (e.g., between parents and children, friends, generals and their armies, business partners, citizens and the state), a commitment to ideals, or the pursuit of significant goals is clearly of general philosophical interest, as is the examination of potential connections between faith and topics such as trust or reliance.

Five experiments investigated how people use categories to make inductions about objects whose categorisation is uncertain. Normatively, they should consider all the categories the object might be in and use a weighted combination of information from all the categories: bet-hedging. The experiments presented people with simple, artificial categories and asked them to make an induction about a new object that was most likely in one category but possibly in another. The results showed that the majority of people focused on the (...) most likely category in making inductions, although there was a group of consistently normative responders who used information from both categories (about 25% of our college population). Across experiments the overall pattern of results suggests that performance in the task is improved not by understanding the underlying principles of bet-hedging but by increasing the likelihood that multiple categories are in working memory at the time of the induction. We discuss implications for improving everyday inductions. (shrink)

Hilbert’s unpublished 1917 lectures on logic, analyzed here, are the beginning of modern metalogic. In them he proved the consistency and Post-completeness (maximal consistency) of propositional logic -results traditionally credited to Bernays (1918) and Post (1921). These lectures contain the first formal treatment of first-order logic and form the core of Hilbert’s famous 1928 book with Ackermann. What Bernays, influenced by those lectures, did in 1918 was to change the emphasis from the consistency and Post-completeness of a logic to its (...) soundness and completeness: a sentence is provable if and only if valid. By 1917, strongly influenced by PM, Hilbert accepted the theory of types and logicism -a surprising shift. But by 1922 he abandoned the axiom of reducibility and then drew back from logicism, returning to his 1905 approach of trying to prove the consistency of number theory syntactically. (shrink)

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)

Erving Goffman's distinctive contribution to an understanding of others was grounded in his information control and ritual models of the interaction process. This contribution centered on the forms of the interaction order rather than self-other relations as traditionally conceived in phenomenology. Goffman came to phenomenology as a sympathetic but critical outsider who sought resources for the sociological mining of the interaction order. His engagement with phenomenological thinkers (principally Gustav Ichheiser, Jean-Paul Sartre and Alfred Schutz) has to be understood in these (...) terms. The article traces basic differences in analytical focus through a range of phenomenological critiques of Goffman and a comparison of salient aspects of Schutz's and Goffman's writings. While the contrasts have perhaps been overplayed, I conclude that Goffman's thinking about others probably owed more to his pragmatist roots than to his later encounters with phenomenology. (shrink)

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.

A majority opinion seems to have emerged in scholarly analysis of the assortment of technologies that have been given the label “synthetic biology.” According to this view, society should allow the technology to proceed and even provide it some financial support, while monitor­ing its progress and attempting to ensure that the development leads to good outcomes. The near‐consensus is captured by the U.S. Presidential Commission for the Study of Bioethical Issues in its report New Directions: The Ethics of Synthetic Biology (...) and Emerging Technologies, which arguably marked the end of a preliminary round of analysis about the ethical and policy questions raised by synthetic bi­ology. Like a number of other, earlier documents issued by various groups around the world, the re­port called attention to questions about how the technology will be used; whether it might be mis­used; what sorts of accidents might happen along the way; the economic, environmental, and social impacts of the eventual applications; whether the very idea of “synthetic biology” should be trou­bling; and how the debate over all of these ques­tions will be conducted. Also like most similar documents, however, while it called for careful monitoring and oversight of technology, it did not recommend any significant new constraints on its development and use. The commission's stance was that it would be “imprudent either to declare a moratorium on synthetic biology until all risks can be determined and mitigated, or to simply ‘let science rip,’ regardless of the likely risks.”In this report, we will take stock of the current consensus, comment on some of the major points of disagreement, and identify the next steps for the debate. In part I, we offer a brief overview of the research and applications commonly grouped together under the heading of synthetic biology, partly in order to set the stage for the rest of the discussion and partly because we want to highlight some conceptual problems that attend the very la­bel given this field. In parts II, III, and IV, we take up, respectively, three broad classes of concerns that arise in the context of synthetic biology: con­cerns about the intrinsic or inherent value of do­ing synthetic biology, concerns about the concrete harms and benefits of doing synthetic biology, and concerns about justice. Addressing these concerns requires a method for bringing the public's values to bear on policy‐making concerning emerging biotechnologies; in part V, we discuss the chal­lenges in developing such a method.

What has been the historical relationship between set theory and logic? On the one hand, Zermelo and other mathematicians developed set theory as a Hilbert-style axiomatic system. On the other hand, set theory influenced logic by suggesting to Schröder, Löwenheim and others the use of infinitely long expressions. The questions of which logic was appropriate for set theory - first-order logic, second-order logic, or an infinitary logic - culminated in a vigorous exchange between Zermelo and Gödel around 1930.

Prior to the end of the Cold War, the word 'democracy' was rarely used by international lawyers. Few international organisations supported democratic governance, and the criteria for recognition of governments took little account of whether regimes enjoyed a popular mandate. But the events of 1989–1991 profoundly shook old assumptions. Democratic Governance and International Law attempts to assess international law's new-found interest in fostering transitions to democracy. Is an entitlement to democratic government now emerging in international law? If so, what are (...) its normative foundations? How have global and regional organisations encouraged transitions to democracy, and are their efforts consistent with their constitutional frameworks? How should international law react to elections in which profoundly anti-democratic parties win the vote? In this volume, leading legal scholars grapple with these and other questions to assess the future of international law on this most domestic of questions. (shrink)

This paper explores how the Generalized Continuum Hypothesis (GCH) arose from Cantor's Continuum Hypothesis in the work of Peirce, Jourdain, Hausdorff, Tarski, and how GCH was used up to Gödel's relative consistency result.

This paper describes the application of eight statistical and machine-learning methods to derive computer models for predicting mortality of hospital patients with pneumonia from their findings at initial presentation. The eight models were each constructed based on 9847 patient cases and they were each evaluated on 4352 additional cases. The primary evaluation metric was the error in predicted survival as a function of the fraction of patients predicted to survive. This metric is useful in assessing a model’s potential to assist (...) a clinician in deciding whether to treat a given patient in the hospital or at home. We examined the error rates of the models when predicting that a given fraction of patients will survive. We examined survival fractions between 0.1 and 0.6. Over this range, each model’s predictive error rate was within 1% of the error rate of every other model. When predicting that approximately 30°K of the patients will survive, all the models have an error rate of less than 1.5%. The models are distinguished more by the number of variables and parameters that they contain than by their error rates; these differences suggest which models may be the most amenable to future implementation as paper-based guidelines.

There exists substantial cultural variation in how emotions are expressed, but there is also considerable evidence for universal properties in facial and vocal affective expressions. This is the first empirical effort examining the perception of vocal emotional expressions across cultures with little common exposure to sources of emotion stimuli, such as mass media. Shuar hunter-horticulturalists from Amazonian Ecuador were able to reliably identify happy, angry, fearful and sad vocalizations produced by American native English speakers by matching emotional spoken utterances to (...) emotional expressions portrayed in pictured faces. The Shuar performed similarly to English speakers who heard the same utterances in a content-filtered condition. These data support the hypothesis that vocal emotional expressions of basic affective categories manifest themselves in similar ways across quite disparate cultures. (shrink)

What gave rise to Ernst Zermelo's axiomatization of set theory in 1908? According to the usual interpretation, Zermelo was motivated by the set-theoretic paradoxes. This paper argues that Zermelo was primarily motivated, not by the paradoxes, but by the controversy surrounding his 1904 proof that every set can be wellordered, and especially by a desire to preserve his Axiom of Choice from its numerous critics. Here Zermelo's concern for the foundations of mathematics diverged from Bertrand Russell's on the one hand (...) and from Felix Hausdorff's on the other. (shrink)

Elite U.S.-based global law firms concentrate in the costliest districts of superstar cities, especially two neighborhoods in Manhattan. This pattern has persisted despite both the dispersal of Biglaw clients across less-dense, lower-cost U.S. geographies and the development of telework capacity. It suggests a puzzle: law is among the occupations most conducive to remote work, yet Biglaw prior to the coronavirus pandemic required in-person work in the priciest places—meaning it paid a premium on both of its biggest expenses, wages and real (...) estate. How might this equilibrium be explained, and what might lead it to change? This Article contends that Biglaw clustering reflects a management preference for the exploitation of proven strategies over the exploration of novel and uncertain ones—but that the pandemic telework experience is eroding this dichotomy. This analysis has direct implications for private international law practice, where large-scale transactions and disputes are handled by Biglaw firms and involve significant international travel. This Article contributes to a growing literature on telework’s impacts on cities, labor markets, and industries, and is the first to extend that focus to Biglaw and PIL. A post-pandemic Biglaw embrace of dispersal via telework would destabilize standard accounts of collaboration in agglomeration economies. While the Article expresses skepticism about that outcome, it identifies a mechanism by which it might plausibly come about. Crucially, this mechanism—the replacement of an exploit vs. explore choice with two different exploit options—posits as the key driver not technology but management learning and innovation that quickened during the pandemic.

Starting with the Apollonian Greek theory of techne, Means Without End presents a history of transformations of ideas about technology, viewed within their broader philosophical, theological, and scientific contexts. Critically focusing on the ideological genealogy of technology without limits and finding its cultural roots in Christian theology, it details ideological developments in the Renaissance, Enlightenment, and 19th century which prepared the way for a theory of autonomous technology and for postmodern technoculture in the 20th century.

Although in Drosophila pair‐rule genes play crucial roles in the genetic hierarchy that subdivides the embryo into segments, the extent to which pair‐rule patterning is utilized by different arthropods and other segmented phyla is unknown. Recent data of Dearden et al.1 and Henry et al.,2 however, hint that a pair‐rule mechanism might play a role in the segmentation process of basal arthropods and vertebrates.

Supporting Hamilton’s inclusive fitness theory, archival analyses of inheritance patterns in wills have revealed that people invest more of their estates in kin of closer genetic relatedness. Recent classroom experiments have shown that this genetic relatedness effect is stronger for relatives of direct lineage (children, grandchildren) than for relatives of collateral lineage (siblings, nieces, nephews). In the present research, multilevel modeling of more than 1,000 British Columbian wills revealed a positive effect of genetic relatedness on proportions of estates allocated to (...) relatives. This effect was qualified by an interaction with lineage, such that it was stronger for direct than for collateral relatives. Exploratory analyses of the moderating role of benefactors’ sex and estate values showed the genetic relatedness effect was stronger among female and wealthier benefactors. The importance of these moderators to understanding kin investment in modern humans is discussed. (shrink)

This volume shows Russell in transition from a neo-Kantian and neo-Hegelian philosopher to an analytic philosopher of the first rank. During this period his research centred on writing The Principles of Mathematics where he drew together previously unpublished drafts. These shed light on Russell's paradox. This material will alter previous accounts of how he discovered his paradox and the related paradox of the largest cardinal. The volume also includes a previously unpublished draft of an early attempt to solve his paradox, (...) as well as the earliest known version of his generalised relation arithmetic. It contains three articles which have never previously been published in English. (shrink)

This volume of Bertrand Russell's _Collected Papers_ finds Russell focused on writing _Principia Mathematica_ during 1905–08. Eight previously unpublished papers shed light on his different versions of a substitutional theory of logic, with its elimination of classes and relations, during 1905-06. A recurring issue for him was whether a type hierarchy had to be part of a substitutional theory. In mid-1907 he began writing up the final version of _Principia_, now using a ramified theory of types, and eleven unpublished drafts (...) from 1907-08 deal with this. Numerous letters show his thoughts on the process. The volume's 80-page introduction covers the evolution of his logic from 1896 until 1909, when volume I of _Principia _went to the printer.

The study of the early manuscripts of the great authors most often becomes a process of monumentalising or (re)legitimising their work. The recent publication of two of Sartre's early manuscripts – first Empédocle (Empedocles) in 2016 and second, in 2018, his dissertation for his graduate diploma (diplôme d’études supérieures or DES), L'Image dans la vie psychologique (The Image in Psychological Life), both texts written in 1926–1927 – encourages us to propose another type of genetic reading that insists on the collective (...) conditions of the production of knowledge, including philosophical knowledge. Such a collective genetics, applied to Sartre's intellectual formation during the interwar years, allows us to highlight some of the little-known forms of Parisian intellectual societies (the activities of the International Information Group of the École Normale Supérieure, the critical logic of the psychology journals, the regular meetings of the cenacles, and the literary and philosophical research groups). It also reveals, at the same time, the original relationship between Sartre's thought and the German literature and philosophy mediated to him by Bernard Groethuysen, Stefan Zweig and Alexandre Koyré.
