We evaluate the “story grammar” approach to story understanding from three perspectives. We first examine the formal properties of the grammars and find only one to be formally adequate. We next evaluate the grammars empirically by asking whether they generate all simple stories and whether they generate only stories. We find many stories that they do not generate and one major class of nonstory that they do generate. We also evaluate the grammars' potential as comprehension models and find that they (...) would add nothing to semantic models that focus on the story content. Hence we advocate a story content oriented approach to studying story understanding instead of the structural story grammar approach. (shrink)

It is difficult to study failed medical devices because of a lack of data. Routine device retrieval and analysis (DRA) is essential to performance evaluation, which, in turn, is essential to good patient care. We argue for the development of a national DRA program and medical device database and discuss the major ethical and policy issues associated with this proposal.

A productive way to think about imagistic mental models of physical systems is as though they were sources of quasi‐empirical evidence. People depict or imagine events at those points in time when they would experiment with the world if possible. Moreover, just as they would do when observing the world, people induce patterns of behavior from the results depicted in their imaginations. These resulting patterns of behavior can then be cast into symbolic rules to simplify thinking about future problems and (...) to reveal higher order relationships. Using simple gear problems, three experiments explored the occasions of use for, and the inductive transitions between, depictive models and number‐based rules. The first two experiments used the convergent evidence of problem‐solving latencies, hand motions, referential language and error data to document the initial use of a model, the induction of rules from the modeling results, and the fallback to a model when a rule fails. The third experiment explored the intermediate representations that facilitate the induction of rules from depictive models. The strengths and weaknesses of depictive modeling and more analytic systems of reasoning are delineated to motivate the reasons for these transitions. (shrink)

One cannot summarize the intent of this insightful and engaging book better than the author himself: “The thesis... is that CTM [the Computational Theory of Mind] does not provide a solution to the philosophical problems that it is heralded as solving—indeed, it involves some deep confusions about computers, symbols, and meaning—but that this does not undercut the possibility that the computer paradigm may provide an important resource... for the development of a mature science of cognition”.

This paper shows how John R. Commons’ analysis of a firm’s goodwill value gives analytical support to Professor Amartya Sen’s contention (BEQ, 1993) that business ethics makes economic sense. A firm’s market value consists of the value of both tangible and intangible capital, including the goodwill value of ongoing customer relations. If a firm is to defend its goodwill value, it needs to have the protection of the courts and to pursue ethical practices. The courts defend fair competition by (...) giving protection from unethical competitors while the firm defends its reputation with honest dealings.By implication, firms which depend on ongoing customer relations will tend to engage in more ethical business practices than firms which do not. Even a firm which makes a mistake that compromises its product’s safety may reduce the loss of goodwill value over time by admitting the mistake early rather than hiding it.Also by implication, the transition from a command socialist economy to a market economy cannot be made instantaneously since trust, reputation, and these ongoing customer relations-key institutions of market economics-cannot be generated instantaneously.

The late John Austin's William James Lectures 1 might well have borne the subtitle ‘In Pursuit of a Vanishing Distinction’. Although the chase is remorseless, glimpses of the quarry become increasingly equivocal and the hunter is left empty-handed at last. It is hard to know what has gone awry. Has the wrong game been pursued—and in the wrong direction?

John Griffi n’s classic on racism, Black Like Me (1960), provides an interesting text with which to investigate the development of a dialogical self. Griffi n becomes a black man for only a short period of time, but during that time he develops a black social identity and sense of personal identity, that contrasts radically with his former white identity. When he looks into a mirror on several occasions he engages in a dialogue with himself, as (...) both a black and a white person. At fi rst these two identities are so different that there is no “sympathy” between them. But through his experience, he eventually overcomes the dichotomy of two opposing selves, and acquires a personal identity, neither white nor black, but just human. In this article, I trace the development of these dialogical selves and the emergence of this new human identity. Key words: identity, racism, self, black, white.. (shrink)

Black hole thermodynamics is regarded as one of the deepest clues we have to a quantum theory of gravity. It motivates scores of proposals in the field, from the thought that the world is a hologram to calculations in string theory. The rationale for BHT playing this important role, and for much of BHT itself, originates in the analogy between black hole behavior and ordinary thermodynamic systems. Claiming the relationship is “more than a formal analogy,” black holes (...) are said to be governed by deep thermodynamic principles: what causes your tea to come to room temperature is said additionally to cause the area of black holes to increase. Playing the role of philosophical gadfly, we pour a little cold water on the claim that BHT is more than a formal analogy. First, we show that BHT is often based on a kind of caricature of thermodynamics. Second, we point out an important ambiguity in what systems the analogy is supposed to govern, local or global ones. Finally, and perhaps worst, we point out that one of the primary motivations for the theory arises from a terribly controversial understanding of entropy. BHT may be a useful guide to future physics. Only time will tell. But the analogy is not nearly as good as is commonly supposed. (shrink)

As Louisiana and Cuba emerged from slavery in the late nineteenth century, each faced the question of what rights former slaves could claim. Degrees of Freedom compares and contrasts these two societies in which slavery was destroyed by war, and citizenship was redefined through social and political upheaval. Both Louisiana and Cuba were rich in sugar plantations that depended on an enslaved labor force. After abolition, on both sides of the Gulf of Mexico, ordinary people-cane cutters and cigar workers, laundresses (...) and labor organizers-forged alliances to protect and expand the freedoms they had won. But by the beginning of the twentieth century, Louisiana and Cuba diverged sharply in the meanings attributed to race and color in public life, and in the boundaries placed on citizenship. Louisiana had taken the path of disenfranchisement and state-mandated racial segregation; Cuba had enacted universal manhood suffrage and had seen the emergence of a transracial conception of the nation. What might explain these differences? Moving through the cane fields, small farms, and cities of Louisiana and Cuba, Rebecca Scott skillfully observes the people, places, legislation, and leadership that shaped how these societies adjusted to the abolition of slavery. The two distinctive worlds also come together, as Cuban exiles take refuge in New Orleans in the 1880s, and black soldiers from Louisiana garrison small towns in eastern Cuba during the 1899 U.S. military occupation. Crafting her narrative from the words and deeds of the actors themselves, Scott brings to life the historical drama of race and citizenship in postemancipation societies. (shrink)

Why is the human imagination to blame for the worst crimes of the twentieth century? Why is progress a pernicious myth? Why is contemporary atheism just a hangover from Christian faith? John Gray, author of Straw Dogsand Black Mass, is one of the most original and iconoclastic thinkers of our time. In this pugnacious and brilliantly readable collection of essays from across his career, he smashes through humanity's most cherished beliefs to overturn our view of the world, and (...) our place in it. 'If humans are different from other animals it is chiefly in being governed by myths, which are not creations of the will but creatures of the imagination.' 'No traditional myth is as untruthful as the modern myth of progress. All prevailing philosophies embody the fiction that human life can be altered at will. Better aim for the impossible, they say, than submit to fate. Invariably, the result is a cult of human self-assertion that soon ends in farce.'. (shrink)

John Arthur philosophically addresses the problems of racism and the legacy of past racial discrimination in the United States. Offering a thorough analysis of the concepts of race and racism, Arthur also discusses racial equality, poverty and race, reparations and affirmative action, and merit in ways that cut across the usual political lines. A philosopher, former civil-rights plaintiff and professor at an historically black college in the South, Arthur draws on both his personal experiences as well as his (...) rigorous philosophical training in this account. His conclusions about the meaning of merit, the defects of affirmative action, the importance of apology, and the need for true equality deal productively with one of America's most vexing problems. His book is also relevant to any society struggling with racial differences and past injustices. (shrink)

This article considers the theological influences on the Balfour Declaration which was made on the 2 November 1917 and for the first time gave British governmental support to the establishment of a Jewish homeland in Palestine. It explores the principal personalities and political workings behind the Declaration before going on to argue the statement cannot be entirely divested from the religious sympathies of those involved, especially Lord Balfour. Thereafter, the paper explores the rise of Christian Restorationism in the context of (...) Scottish Presbyterianism, charting how the influence of Jonathan Edwards shaped the thought of Thomas Chalmers on the role of the Jews in salvation history which in turn influenced the premillennialism of Edward Irving and his Judeo-centric eschatology. The paper then considers the way this eschatology became the basis of John Darby’s premillennial dispensationalism and how in an American context this theology began to shape the thinking of Christian evangelicals and through the work of William Blackstone provide the basis of popular and political support for Zionism. However, it also argues the political expressions of premillennial dispensationalism only occurred in America because the Chicago evangelist Dwight L. Moody was exposed to the evolving thinking of Scottish Presbyterians regarding Jewish restoration. This thinking had emerged from a Church of Scotland ‘Mission of Inquiry’ to Palestine in 1839 and been advanced by Alexander Keith, Horatius Bonar and David Brown. Finally, the paper explores how this Scottish Presbyterian heritage influenced the rise of Zionism and Balfour and his political judgements. (shrink)

In South Africa under apartheid, portrait images displayed in private homes emphasised the dignity of their subjects and the stability of family life during a period of indignity and social upheaval. But when interviewing families about them, one often encounters sensitivity issues of the sort too often passed over by scholars and curators who valorise studio practices without consulting the actual subjects of the images. These include a range of anxieties about repackaging for display in new contexts and for broader (...) audiences, as well as basic copyright and authorship concerns in common with other African and 'family' photographies. The particular anxieties themselves speak to the local histories of how these self-images were used and lived. This essay argues for a closer consideration and a new ethics for looking at and writing about these pictures. It is based on research since 2010 on family collections of photographs in South Africa's Black urban neighbourhoods. (shrink)

John Ogbu has studied minority education from a comparative perspective for over 30 years. The study reported in this book--jointly sponsored by the community and the school district in Shaker Heights, Ohio--focuses on the academic performance of Black American students. Not only do these students perform less well than White students at every social class level, but also less well than immigrant minority students, including Black immigrant students. Furthermore, both middle-class Black students in suburban school districts, (...) as well as poor Black students in inner-city schools are not doing well. Ogbu's analysis draws on data from observations, formal and informal interviews, and statistical and other data. He offers strong empirical evidence to support the cross-class existence of the problem. The book is organized in four parts: *Part I provides a description of the twin problems the study addresses--the gap between Black and White students in school performance and the low academic engagement of Black students; a review of conventional explanations; an alternative perspective; and the framework for the study. *Part II is an analysis of _societal and school factors_ contributing to the problem, including race relations, Pygmalion or internalized White beliefs and expectations, levelling or tracking, the roles of teachers, counselors, and discipline. *_Community factors_--the focus of this study--are discussed in Part III. These include the educational impact of opportunity structure, collective identity, cultural and language or dialect frame of reference in schooling, peer pressures, and the role of the family. This research focus does _not_ mean exonerating the system and blaming minorities, nor does it mean neglecting school and society factors. Rather, Ogbu argues, the role of community forces should be incorporated into the discussion of the academic achievement gap by researchers, theoreticians, policymakers, educators, and minorities themselves who genuinely want to improve the academic achievement of African American children and other minorities. *In Part IV, Ogbu presents a summary of the study's findings on community forces and offers recommendations--some of which are for the school system and some for the Black community. _Black American Students in an Affluent Suburb: A Study of Academic Disengagement_ is an important book for a wide range of researchers, professionals, and students, particularly in the areas of Black education, minority education, comparative and international education, sociology of education, educational anthropology, educational policy, teacher education, and applied anthropology.

What perhaps you did not know is that centrifugal force is, strictly speaking, not a force at all. It is a pseudo-force. It is, in a sense, an illusion produced by changing coordinate systems. This is a slippery idea which will require some explanation. So to understand why centrifugal force is not a true physical force, let's start by considering what the true forces of nature are.

For three days in April, 2005, I was a speaker and panelist at the NASA-sponsored “Physics for the rd Millennium II Conference” in Huntsville, Alabama, where twelve of us, including two Nobel Laureates, were invited to give 50-minute lectures about cutting-edge physics to an audience of NASA engineers, teachers, students, parents, and other interested attendees. In this column, I want to tell you about the work described in one of the talks, given by Dr. George Chapline of the Lawrence Livermore (...) Laboratory. (shrink)

This column is a milestone. It's the 100 th Alternate View column that I've written for Analog over a period of 16 years beginning in 1983. I was on a sabbatical in Berlin when Stan recruited me to write the column after Jerry Pournelle, my predecessor as AV columnist, decided to step down. The AV columns are a soapbox that was too attractive to pass up, and I've used them to promote an interst in science and to feed cutting-edge science (...) ideas, primarily in the areas of physics and astrophysics, to the readers and writers of science fiction.

The Large Hadronic Collider (LHC), which is to be the world’s highest energy particle accelerator, is currently being constructed at the CERN laboratory in Geneva, Switzerland. The machine was designed to be high enough in energy to produce a completely new type of particle, the Higgs boson, which is considered to be the missing puzzle-piece in the Standard Model of particle interactions. According to current theoretical thinking, it is the Higgs particle that gives mass to all the other particles, quarks, (...) leptons, etc., in the current bestiary of fundamental particles.

The old quantum theory of black body radiation was manifestly logically inconsistent. It required the energies of electric resonators to be both quantized and continuous. To show that this manifest inconsistency was inessential to the theory's recovery of the Planck distribution law, I extract a subtheory free of this manifest inconsistency but from which Planck's law still follows.

Although decision‐making algorithms are not new to medicine, the availability of vast stores of medical data, gains in computing power, and breakthroughs in machine learning are accelerating the pace of their development, expanding the range of questions they can address, and increasing their predictive power. In many cases, however, the most powerful machine learning techniques purchase diagnostic or predictive accuracy at the expense of our ability to access “the knowledge within the machine.” Without an explanation in terms of reasons or (...) a rationale for particular decisions in individual cases, some commentators regard ceding medical decision‐making to black box systems as contravening the profound moral responsibilities of clinicians. I argue, however, that opaque decisions are more common in medicine than critics realize. Moreover, as Aristotle noted over two millennia ago, when our knowledge of causal systems is incomplete and precarious—as it often is in medicine—the ability to explain how results are produced can be less important than the ability to produce such results and empirically verify their accuracy.
