In the modern world, many important tasks have become too complex for a single unaided individual to manage. Teams conduct some safety-critical tasks to improve task performance and minimize the risk of error. These teams have traditionally consisted of human operators, yet, nowadays, artificial intelligence and machine systems are incorporated into team environments to improve performance and capacity. We used a computerized task modeled after a classic arcade game to investigate the performance of human–machine and human–human teams. We manipulated the (...) group conditions between team members; sometimes, they were instructed to collaborate, compete, or work separately. We evaluated players' performance in the main task (gameplay) and, in post hoc analyses, participant behavioral patterns to inform group strategies. We compared game performance between team types (human–human vs. human–machine) and group conditions (competitive, collaborative, independent). Adapting workload capacity analysis to human–machine teams, we found performance under both team types and all group conditions suffered a performance efficiency cost. However, we observed a reduced cost in collaborative over competitive teams within human–human pairings, but this effect was diminished when playing with a machine partner. The implications of workload capacity analysis as a powerful tool for human–machine team performance measurement are discussed. (shrink)

Recent stories of corporate insiders avoiding losses and, in some cases, generating enormous personal profits as their companies crumbled have led investors to question the integrity of American business and the fairness of the United States stock markets. The SEC tries to ensure the fairness of the stock markets by making and enforcing laws against unfair practices such as insider trading. In the United States, when insiders trade stock based on non-public information, they have broken the law and betrayed the (...) trust that has been placed in them.This study used student subjects to test the relationship between the likelihood of trading based on insider information and subjective probabilities of deterrents and motivations for insider trading. Expected gain, guilt, cynicism, and fairness of laws were the determinants that had a significant relationship with the intent to trade based on insider information. This study also found support for prospect theory with regard to insider trading. The results indicate that subjects are more likely to trade based on insider information to avoid a loss than to achieve an abnormal gain. The study also finds evidence of social desirability response bias. (shrink)

Solid state physics, the study of the physical properties of solid matter, was the most populous subfield of Cold War American physics. Despite prolific contributions to consumer and medical technology, such as the transistor and magnetic resonance imaging, it garnered less professional prestige and public attention than nuclear and particle physics. Solid State Insurrection argues that solid state physics was essential to securing the vast social, political, and financial capital Cold War physics enjoyed in the twentieth century. Solid state’s technological (...) bent, and its challenge to the “pure science” ideal many physicists cherished, helped physics as a whole respond more readily to Cold War social, political, and economic pressures. Its research kept physics economically and technologically relevant, sustaining its cultural standing and policy influence long after the sheen of the Manhattan Project had faded. (shrink)

Much of the recent discussion of problematic aspects of quantum-mechanical measurement centers around that feature of quantum theory which is called "the projection postulate." This is roughly the claim that a change of a certain sort occurs in the state of a physical system when a measurement is made on the system. In this paper an argument for the projection postulate due to von Neumann is considered. Attention is focused on trying to provide an understanding of the notion of "the (...) state of a physical system" which is compatible with the argument von Neumann offers. An attempt is made to formulate the argument in terms of an objectivistic interpretation of probability concepts. It is seen that such an interpretation does not provide a suitable way of understanding the argument. An attempt is made to illustrate the source of this failure in terms of a non-quantum-mechanical example. (shrink)

The theory of subjective probability and utility recently proposed by professor richard jeffrey has several unique features and appears to be in some ways distinctly more satisfactory than earlier theories. There is, However, One very important class of decision problems which is not discussed by professor jeffrey--Problems concerned with decisions about strategies for using information. The principal task of this paper is to point out some questions which arise in attempting to deal with these decision problems within jeffrey's theory. To (...) do this it will be necessary to examine in some detail jeffrey's discussion of the relation between his theory and those of ramsey and savage. (shrink)

The contingentist/inevitabilist debate contests whether the results of successful science are contingent or inevitable. This article addresses lingering ambiguity in the way contingency is defined in this debate. I argue that contingency in science can be understood as a collection of distinct concepts, distinguished by how they hold science contingent, by what elements of science they hold contingent, and by what those elements are contingent upon. I present a preliminary taxonomy designed to characterize the full-range positions available and illustrate that (...) these constitute a diverse array rather than a spectrum. (shrink)

In psychoanalysis, enlivenment is seen as residing in a sense of self, and this sense of self is drawn from and shaped by lived experience. _Enlivening the Self: The First Year, Clinical Enrichment, and the Wandering Mind _describes the vitalizing and enrichment of self-experience throughout the life cycle and shows how active experience draws on many fundamental functional capacities, and these capacities come together in support of systems of motivation; that is, organized dynamic grouping of affects, intentions, and goals. The (...) book is divided into three essays: Infancy – _Joseph Lichtenberg_ presents extensive reviews of observation and research on the first year of life. Based on these reviews, he delineates twelve foundational qualities and capacities of the self as a doer doing, initiating and responding, activating and taking in. Exploratory therapy – _James L. Fosshage _looks where therapeutic change is entwined with development. There are many sources illustrated for enhancing the sense of self, and _Frank M. Lachmann _pays particular attention to humor and to the role that the twelve qualities and capacities play in the therapeutic process. The wandering mind – _Frank M. Lachmann _covers the neuroscience and observation that "mind wandering" is related to the immediacy of the sense of self linking now with past and future. Throughout the book the authors’ arguments are illustrated with rich clinical vignettes and suggestions for clinical practice. This title will be a must for psychoanalysts, including trainees in psychoanalysis, psychiatry residents and candidates at psychoanalytic institutes and also graduate students in clinical and counselling psychology programs.

A method of using co-citation data to identify scientific specialties and trace their development through time is outlined. These are related to the structuralist "theory net" construct. The method is purely "theoretical in that no algorithms for implementing the method are suggested. Even at this theoretical level, the discussion is incomplete in several ways. Important formal properties of some of the concepts employed remain to be clarified. The specific way these constructs relate to theory nets remains to be specified in (...) detail. (shrink)

If a transformation in medicine occurs in the wake of the Human Genome Project, its likely focus will be prevention, a logical extension of the lessons of variation and individuality inherent in molecular genetics. The transformation of medicine will require a transformation in genetics education as well, focusing on the development of genetic literacy that allows patient and provider to collaborate as partners in health promotion and disease prevention. The components of genetic literacy include new views of genetics and of (...) disease, and attention to the nature of science, the principles of technology, and ethical, legal, and social implications of genetic medicine.

A major theme in biological research is the quest for mechanism, embodied in explanatory reductionism: the interpretation of phenomena through links to the entities and laws of more fundamental sciences. For example, the form of Starling's Law of the Heart, relating contractile force to heart volume, follows from the sliding-filament hypothesis of muscle contraction, a molecular concept. Although alternative mechanisms for muscle contraction and cardiac regulation could be deduced from biochemical principles, the formulation provides clear correspondence with the phenomena and (...) a deeper understanding of cardiac function. Moreover, even if the reduction provides no better formulation of the phenomenon, of the macro-regularity, it is still prized as a nearer approach to physical reality, as a step toward realizing fundamental unities and codifying general principles, and as a door to new experimental opportunities.

Originally published in 1983 _Reflections on Self Psychology_ records the development of a powerful initiative to alter psychoanalytic theory and practice, and an evaluative questioning of this initiative. It presents a dialogue that developed at the Boston Symposium of 1980 between vigorous proponents of self psychology, equally energetic critics, and many participants between these polar positions. This book attempts to capture within its pages not only the content of what was presented, explored, and evaluated in Boston, but also a sense (...) of the people, about 1,000 strong, who exchanged their ideas on and off the podium – and the remarkable spirit of open inquiry that invigorated these proceedings. The book, as was the meeting, is organized to explore four subjects: the development of the self: infant research; the implications of self psychology for psychoanalytic practice; self psychology and psychotherapy; and the implications of self psychology for psychoanalytic theory. The final section of the book is devoted to an essay by Heinz Kohut that provides an integrated response to the issues and criticisms raised in the course of the symposium. This essay while based on extemporaneous responses by Kohut during different phases of the meeting, is, in its written version, a cohesive, carefully revised, and edited statement prepared in the mellowing period following the meeting and before Kohut’s untimely death.

ABSTRACT Though Nietzsche's lifelong fascination with Wagner's Tristan and Isolde is well documented, its impact upon the developmental trajectory of his philosophy and in particular, his thinking on the nature of eroticism remains far from obvious. This article examines the previously unheralded influence of Wagner's opera on Nietzsche's various attempts, throughout the 1880s, at forging an alternative conception of erotic desire—a conception no longer subordinated to the pursuit for fusional reconciliation but rather linked to the eternal return and the unconditional (...) affirmation of distance itself.

The University of Chicago was the site of a remarkable ideological alignment after World War II. Its chancellor, Robert Maynard Hutchins, was one of mid-century America’s fiercest critics of science and of the moral stature of scientists. His administration nevertheless forged a détente with Chicago’s physical scientists in the process of establishing the Institutes for Basic Research, which consolidated the personnel and resources the Manhattan Project had brought to campus. Chicago’s left-leaning group of scientists and administrators then made common cause (...) with a series of conservative industrial interests in order to fund the new institutes, on the basis that industry had an obligation to support basic research. This intersection of otherwise divergent ideological strands exposes the institutional malleability of patronage relationships in the years after World War II.†durha. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Death of Osiris in Aeneid 12.458Joseph D. ReedAs aeneas ranges the battlefield in search of Turnus and the Aeneid storms toward its close, an odd note sounds. A Trojan named Thymbraeus slays a Rutulian named Osiris. Neither is mentioned before or again. Even when one considers the diversity in this poem of names of Italian warriors, which Virgil takes not just from Italian traditions but from all over (...) the Mediterranean world,1 Osiris is surprising. Why does the name of an Egyptian god intrude into a primeval scene of Roman origins? The reader cannot ignore this provocation, especially on recollecting the rich patterns of meaning that such a contemporary of Virgil as Tibullus works into his elegy on Messalla’s birthday through an invocation of Osiris.2 So unexpected is the name that Bergk emended Osirim to Osinim, recalling the Italian king Osinius mentioned at 10.655.3 But emendation is misguided: as this paper will argue, the suggestiveness of the name is satisfied on the levels of history, ideology, religion, and literary influence, all major domains of Virgil’s epic. And the slaying of Osiris by Thymbraeus can be shown to emblematize both the whole mission of Aeneas and the achievement of Augustus.Aeneas, cured of the wound on his thigh, arms himself and, with some final words of instruction to his son, goes into battle seeking Turnus. In a memorable simile, he is compared to a storm that brings horror to farmers and ruin to their crops. His example rouses his fellow Trojans against the Italians: ferit ense gravem Thymbraeus Osirim, Arcetium Mnestheus, Epulonem obtruncat Achates Ufentemque Gyas; cadit ipse Tolumnius augur, primus in adversos telum qui torserat hostis.(12.458–61)[End Page 399]With his sword Thymbraeus smites the gravem Osiris. The adjective is equivalent to fortis, according to Servius Auctus; Forbiger prefers a denotation of towering size, comparing gravis as epithet of the boxer Entellus at 5.437 and 447.4 “Massive” might capture the sense in English. The effect here is to highlight Thymbraeus’ prowess. Like Osiris, two of the other Italian victims, Arcetius and Epulo, are unknown except for this passage. (The important Ufens received six lines at 7.744–49, in the catalogue of Latin allies,5 and Tolumnius, as line 461 reminds us, began this phase of the battle at 12.257–67.)6 But both their names etiologize some ancestral Italic or Roman institution: Epulo suggests a prototype of the college of epulones, priests of Jupiter Epulo;7 Arcetius invites a connection with the Italian gens Arquitia.8 In this they are like their enemy Mnestheus, supposed eponym of the gens Memmia (5.117). Osiris stands alone among his compatriots in his nomenclatural irrelevance to anything Roman. But Thymbraeus shares the isolation of his victim: he is the only one of the Trojans here who is mentioned nowhere else; not only that, but Mnestheus, Achates, and Gyas are indeed famous, leaders of the Trojans throughout the poem, receiving notice during the introductory storm scene in book 1, the departure from Carthage in book 4, the games in honor of Anchises in book 5, and elsewhere. The catalogue here is introduced by a pair of unknown warriors.The two belong together and give each other meaning. If the name of Osiris applied to a follower of Turnus reduces the critic to perplexity and silence, we can approach its significance through that of the name of Thymbraeus, which has obvious relevance to the whole drift of the epic. Thymbraeus reprises a Thymbraeus killed by Diomedes in Iliad 11.320–21, also mentioned only once. Virgil has revived the obscure Trojan, as it were, to permit him the victory at last; the fact that each Thymbraeus is hapax legomenos in his epic reinforces the reference, especially for such learned readers as Virgil himself was and expected in [End Page 400] his audience.9 The name itself, “the Thymbraean man,” comes from the town Thymbra near Troy (first attested in Il. 10.430),10 and so unmistakably marks the first warrior in Virgil’s catalogue as a representative survivor of the fallen city. In fact, the mythological tradition preserves... (shrink)

In this essay I offer a philosophical-political reconstruction of Theodor Adorno's engagements with jazz. Rather than consider whether or not Adorno got jazz 'right', I give an account of how and why Adorno develops the criticisms that he does. I argue that in Adorno's analysis of jazz three interpenetrating claims emerge: (1) a rejection of jazz's sense of improvisation and spontaneity; (2) a demonstration of jazz's entwinement with the modern technologiza tion of everyday life; and (3) a critique of jazz's (...) pseudo-individualiz ing tendencies. I conclude with a brief consideration of the place and critical possibilities of music in Adorno's critique of modernity. Key Words: capitalism • democracy • modernity • pseudo individualization • rescuing critique. (shrink)

This article develops a sociological reading of Walter Benjamin’s ‘Arcades Project’, or Passagen-werk . Specifically, the essay seeks to make explicit Benjamin’s non-dualistic account of structure and agency in the urban milieu. I characterize this account as the ‘dialectic of urbanism’, and argue that one of the central insights of Benjamin’s Passagen-werk is that it locates an emergent and innovative cultural form - a distinctive ‘street culture’ or jointly shared way of modern urban life - within haussmannizing techniques of architectural (...) administration and spatial domination. In the modern metropolis, Benjamin sees a new kind of collective - an embedded and effervescent sociocultural group held together not by the functionalist imperatives of capitalist urban planning but by an improvisational mode of street life. Key Words: agency • culture • embeddedness • structure • urbanism. (shrink)

Recent years have witnessed the publication of numerous articles that draw a critical alignment between ethics and caring. In essence, this theme suggests that caring is a moral pursuit centred on the beneficent attention of one person shown to another. Yet, if such language is to have real poignancy, it must be geared towards an inclusive agenda that meets the needs of all within the community. Research evidence suggests that this is not always the case, especially in terms of the (...) care offered to members of minority ethnic groups. This article will focus on the findings of a qualitative research study that explored the expectations and perceived experiences of nursing care among members of the Pakistani community in Bradford, West Yorkshire, UK. The findings suggest that nurses should develop a more informed narrative that readily reflects the needs of the Pakistani community. (shrink)

Particle theories intend to describe the fundamental constituents from which all matter is constructed and the interactions among them. These constituents include atoms and molecules as well as their subatomic constituents, nuclei and their component parts including elementary particles. We consider an alternative to the usual particle theories, but dealing with the same phenomena. We call these theories ‘QT’s’. This is an attempt to provide a formal description of the essential features of elementary particle theories within the framework of metatheoretical (...) structuralism. (shrink)

This paper explores the process by which new technologies supplant or constrain cultural scaffolding processes and the consequences thereof. As elaborated by William Wimsatt and James Griesemer, cultural scaffolds support the acquisition of new capabilities by individuals or organizations. When technologies displace scaffolds, those who previously acquired capabilities from them come to rely upon the new technologies to complete tasks they could once accomplish on their own. Therefore, the would-be beneficiaries of those scaffolds are deprived of the agency to exercise (...) the capabilities the scaffolds supported. Evaluating how technologies displace cultural scaffolds can ground philosophical assessments of the cultural value of technologies. (shrink)

This article is an analysis of Anthony Giddens' attempt to articulate a globalization-friendly alternative to traditional social democracy (the `old' Left) and neo-liberal market fundamentalism (the `new' Right). Specifically, I focus on Giddens' insistence that globalization is not merely an economic phenomenon but also, and more profoundly, a political and cultural force of `time-space distanciation'. Whereas Giddens conceives of a direct causal connection between the disembedding forces of globalization and outcomes of democratization, I argue that such a conception is deeply (...) flawed. Indeed, rather than develop a politically useful explanatory social theory of the complex relationship between globalization and democracy, Giddens' `third way' theorizing merely hypostatizes the former by invoking it as a cause of the latter. I provide a series of arguments designed to highlight the weaknesses of Giddens' position, and conclude by questioning the general thesis that underlies Giddens' account of globalization. (shrink)

Placed in a historical context, sexuality was once so prominent in psychoanalytic writing that sexual drive and psychoanalysis were synonymous. The exciting discovery of childhood sexuality filled the literature. Then other discoveries came to the fore until sexuality slipped far in the background. This book evokes the excitement of the original discoveries of childhood sexual experience while linking childhood sensuality and sexuality to adult attachment, romantic, and lustful love. This revised perspective offers the general reader insight into contemporary psychoanalytic thought, (...) and presents clinicians with a perspective for exploring their patients sensuality and sexuality with renewed interest and knowledge.
