We consider a special case of heuristics, namely numeric heuristic evaluation functions, and their use in artificial intelligence search algorithms. The problems they are applied to fall into three general classes: single-agent path-finding problems, two-player games, and constraint-satisfaction problems. In a single-agent path-finding problem, such as the Fifteen Puzzle or the travelling salesman problem, a single agent searches for a shortest path from an initial state to a goal state. Two-player games, such as chess and checkers, involve an adversarial relationship (...) between two players, each trying to win the game. In a constraint-satisfaction, problem, such as the 8-Queens problem, the task is to find a state that satisfies a set of constraints. All of these problems are computationally intensive, and heuristic evaluation functions are used to reduce the amount of computation required to solve them. In each case we explain the nature of the evaluation functions used, how they are used in search algorithms, and how they can be automatically learned or acquired. (shrink)

This case deals with the corporate response to a crisis and the successful evacuation of approximately 900 hotel guests, staff, and family members of staff whowere stranded in the Fairmont New Orleans hotel by Hurricane Katrina. This rescue effort, spearheaded by managers at the sister Fairmont hotel in Dallas, Texas, was completed shortly after 12 a.m. on Friday, September 2, 2005, when the last bus with evacuees pulled into the Dallas Fairmont after making a round trip of more than 1000 (...) miles — and about 64 hours after planning began. This case is particularly significant for lessons that may be derived about crisis management and leadership, and it also raises several interesting ethical issues. The case, which relies on field research plus secondary sources, is appropriate for business ethics and business strategy courses. (shrink)

Reviews evidence which suggests that there may be little or no direct introspective access to higher order cognitive processes. Ss are sometimes unaware of the existence of a stimulus that importantly influenced a response, unaware of the existence of the response, and unaware that the stimulus has affected the response. It is proposed that when people attempt to report on their cognitive processes, that is, on the processes mediating the effects of a stimulus on a response, they do not do (...) so on the basis of any true introspection. Instead, their reports are based on a priori, implicit causal theories, or judgments about the extent to which a particular stimulus is a plausible cause of a given response. This suggests that though people may not be able to observe directly their cognitive processes, they will sometimes be able to report accurately about them. Accurate reports will occur when influential stimuli are salient and are plausible causes of the responses they produce, and will not occur when stimuli are not salient or are not plausible causes.

A few years ago I ran across a statement by Jean-Paul Sartre which seemed to imply that if there is a God, then there can be no human freedom. That thesis struck me as questionable, but at the time I did not pause to examine it. More recently I ran across a similar, more explicit statement by Kurt Baier, and I decided the time to pause had come. My knee-jerk response to Baier – and I confess it was probably nothing (...) more – was, ‘Why can't there be human freedom if there is a God? Indeed, can there be human freedom if there isn't a God ?’ The second of these questions has proved to be the more provocative to me, for the more I have thought about it, the more it has seemed to me that it is the atheist and not the theist who should be on the defensive about libertarianism, i.e. the position that human beings do act, that human actions are not determined, that we are the sole cause of our actions, and that all things remaining the same, we could have done otherwise. Indeed, the more I thought about that question – Can there be human freedom if there is no God? – the more convinced I became that the atheist has no good reason for believing in libertarianism. Note: I am not saying that atheism is logically incompatible with libertarianism. Perhaps it is, but if it is, that is not yet obvious to me. Rather, I am saying that an atheist who believes in libertarianism must believe in it on the basis of faith and must hold this faith in opposition to the only type of evidence that is available to him. Hence, by denying the existence of God, Baier and Sartre do not make room for human freedom; they make belief in human freedom irrational. By contrast, I shall argue, the theist does have a good reason for believing that humans are free. Let's take separate looks at Baier and Sartre; then I shall summarize the substance of my position.

The authors find East Asians to be holistic, attending to the entire field and assigning causality to it, making relatively little use of categories and formal logic, and relying on "dialectical" reasoning, whereas Westerners, are more analytic, paying attention primarily to the object and the categories to which it belongs and using rules, including formal logic, to understand its behavior. The 2 types of cognitive processes are embedded in different naive metaphysical systems and tacit epistemologies. The authors speculate that the (...) origin of these differences is traceable to markedly different social systems. The theory and the evidence presented call into question long-held assumptions about basic cognitive processes and even about the appropriateness of the process–content distinction. (shrink)

While reflecting one day on the enormous difficulties that men have in knowing that there is a God, a completely unexpected and unfamiliar question drifted into my purview – perhaps as a kind of ultimate expression of my philosophical frustration. ‘Indeed’, the question asked, ‘can even God know that he is God?’ At first I thought this query merely amusing. ‘Wouldn't it be funny if God cannot know that he is God! But of course he can.’ So my mind wandered (...) on to other things. The question did not leave me alone, though. It insisted that I take it seriously, and the more I did, the more legitimate, complex, and significant it came to seem - and still does. (shrink)

This classic, first published in 1969, introduces to English-speaking readers a field which is of increasing importance in contemporary philosophy and theology--hermeneutics, the theory of understanding, or interpretation. Richard E. Palmer, utilizing largely untranslated sources, treats principally of the conception of hermeneutics enunciated by Heidegger and developed into a "philosophical hermeneutics" by Hans-Georg Gadamer. He provides a brief overview of the field by surveying some half-dozen alternate definitions of the term and by examining in detail the contributions of Friedrich (...) Schleiermacher and Wilhelm Dilthey. In the Manifesto which concludes the book, Palmer suggests the potential significance of hermeneutics for literary interpretation. (shrink)

Staged 2 different videotaped interviews with the same individual—a college instructor who spoke English with a European accent. In one of the interviews the instructor was warm and friendly, in the other, cold and distant. 118 undergraduates were asked to evaluate the instructor. Ss who saw the warm instructor rated his appearance, mannerisms, and accent as appealing, whereas those who saw the cold instructor rated these attributes as irritating. Results indicate that global evaluations of a person can induce altered evaluations (...) of the person's attributes, even when there is sufficient information to allow for independent assessments of them. Furthermore, Ss were unaware of this influence of global evaluations on ratings of attributes. In fact, Ss who saw the cold instructor actually believed that the direction of influence was opposite to the true direction. They reported that their dislike of the instructor had no effect on their rating of his attributes but that their dislike of his attributes had lowered their global evaluations of him. (shrink)

Disputes regarding the ethics of work by children have intensified in recent years, with little resolution. The impasses stem from failure to recognize the diverse forms of child work and a lack of empirical research regarding its causes and consequences. We report on data gathered in Brazil’s export-oriented shoe industry, which is notorious for the employment of children. Central findings are: 1) the causes of child work have less to do with backwardness and more to do with how shoe workers (...) are integrated into the global order; 2) local employers and children regard this work as benign, but the U.S. government sees it as hazardous to children and unfair to U.S. producers; 3) efforts to remove children from the shoe industry have been frustrated by local resistance and raise ethical questions; and 4) in certain circumstances, efforts to eliminate hazards from the workplace are morally superior to campaigns to remove childworkers from employment.

Originated in the West, stakeholder theory is normatively anchored in Western value systems. Differences in value orientations and ethical systems in this global age call for culturally pertinent stakeholder theory. In this article, we argue that Confucianism forms an additional normative basis for stakeholder theory, appropriate for a Confucian context. We demonstrate it through application of Confucianism in major stakeholder relationships. The Confucian stakeholder theory provides a meaningful addition to the corpus of stakeholder literature.

The German volume Gadamer Lesebuch [A Gadamer Reader], selected and edited by Jean Grondin in consultation with Hans-Georg Gadamer himself, contains a set of essays that present a cross section of writings by one of the twentieth century's greatest philosophers. The volume begins with an autobiographical sketch and culminates in a conversation with Jean Grondin that looks back over a lifetime of productive philosophical work. The essays not already available in English have here been translated by Richard E. Palmer, (...) a respected translator of Gadamer's writings. The sixteen essays contained in the Lesebuch are augmented here by three other essays: Gadamer's last essay on Derrida, "Hermeneutics Tracking the Trace" and two essays on practical philosophy. The Gadamer Reader: A Bouquet of the Later Writings richly conveys the scope and depth of Gadamer's thought, covering the range of his work in hermeneutics, aesthetics, practical philosophy, and essays on Plato, Hegel, and Heidegger. In addition, Palmer offers introductory remarks before each essay that explain its importance in the context of Gadamer's writings and define its key terms. Throughout, in both his translation and commentary, his aim is to make this critically important philosopher as clear and accessible as possible to an English-speaking audience. (shrink)

Charles Foster and Jonathan Herring are to be congratulated on their useful presentation of the roles played by concepts of personhood and identity in English medical law.1 However, I fear that the project they have undertaken here is misconceived. It is an interesting and important misconception, which is widely shared in the literature on medical law and ethics; but a misconception it remains. The problem is this. What we call ‘the Law’ is in fact a complex assemblage of institutions, rules, (...) accredited persons, practices and systems. What it is not is a self-sufficient, integrated and self-interpreting system of doctrine. As such it does not have a clear structure which we can excavate and the idea that we can find concepts which explain and unify that structure at some deep level is thus quixotic. To approach ‘the Law’ in that way is to pursue a chimaera. We should instead think of ‘the Law’ as Wittgenstein taught us to approach a language.2 We can find concepts through investigation of language in practical use, but the …. (shrink)
