An important application of cognitive architectures is to provide human performance models that capture psychological mechanisms in a form that can be “programmed” to predict task performance of human–machine system designs. Although many aspects of human performance have been successfully modeled in this approach, accounting for multitalker speech task performance is a novel problem. This article presents a model for performance in a two-talker task that incorporates concepts from psychoacoustics, in particular, masking effects and stream formation.

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.

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)

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.

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)

Offers a critical evaluation of the foundational assumptions and claims, scriptural, theological and philosophical, of John Hick's theocentric critique of the Christian affirmation of Jesus' uniqueness.

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.

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 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 paper combines personal reminiscences of the philosopher John Corcoran with a discussion of certain conflicts between historians of logic and philosophers of logic. Some mistaken claims about the history of the Bolzano-Weierstrass Theorem are analyzed in detail and corrected.

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.

In response to a drying climate, an integrated property planning tool was developed over three years to help landowners make better use of available rainfall. A sequence was identified which indicated how parts of each property are affected by soil moisture limitations. The sequence was combined with soil properties to indicate targeted strategies for each location aimed to improve soil moisture availability, biomass utilisation, and long-term viability of the farm or ranching enterprise. As a result of training of land owners (...) and operators in use of this tool, 97% of participants indicated that they have begun or intend to make changes in land management; 78% are intending to make three or more substantial changes; and 91% felt better prepared for the impacts of climate change. The key to the success of this technique is that it identifies critical sustainable production drivers in a simple plan format and offers tailored management options which can address more variable climate conditions. The integrated planning tool has application as a driver of climate change adaptation in agricultural regions where farm units contain substantial landscape variation and seasonal rainfall is frequently limiting to production.

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)

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.

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)

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)

ABSTRACT Rosalind Franklin is best known for her informative X-ray diffraction patterns of DNA that provided vital clues for James Watson and Francis Crick's double-stranded helical model. Her scientific career did not end when she left the DNA work at King's College, however. In 1953 Franklin moved to J. D. Bernal's crystallography laboratory at Birkbeck College, where she shifted her focus to the three-dimensional structure of viruses, obtaining diffraction patterns of Tobacco mosaic virus (TMV) of unprecedented detail and clarity. During (...) the next five years, while making significant headway on the structural determination of TMV, Franklin maintained an active correspondence with both Watson and Crick, who were also studying aspects of virus structure. Developments in TMV research during the 1950s illustrate the connections in the emerging field of molecular biology between structural studies of nucleic acids and of proteins and viruses. They also reveal how the protagonists of the “race for the double helix” continued to interact personally and professionally during the years when Watson and Crick's model for the double-helical structure of DNA was debated and confirmed.
