There is a long history of cryptographic hash functions, i.e. functions mapping variable-length strings to fixed-length strings, and such functions are also expected to enjoy certain security properties. Hash functions can be effected via modular arithmetic, permutation-based schemes, chaotic mixing, and so on. Herein we introduce the notion of an artificial-life (ALife) hash function (ALHF), whereby the requisite mixing action of a good hash function is accomplished via ALife rules that give rise to complex evolution of a given system. Various (...) security tests have been run, and the results reported for examples of ALHFs. (shrink)

Cognitive Task Analysis (CTA) helps researchers understand how cognitive skills and strategies make it possible for people to act effectively and get things done. CTA can yield information people needemployers faced with personnel issues, market researchers who want to understand the thought processes of consumers, trainers and others who design instructional systems, health care professionals who want to apply lessons learned from errors and accidents, systems analysts developing user specifications, and many other professionals. CTA can show what makes the workplace (...) workand what keeps it from working as well as it might.Working Minds is a true handbook, offering a set of tools for doing CTA: methods for collecting data about cognitive processes and events, analyzing them, and communicating them effectively. It covers both the "why" and the "how" of CTA methods, providing examples, guidance, and stories from the authors' own experiences as CTA practitioners. Because effective use of CTA depends on some conceptual grounding in cognitive theory and researchon knowing what a cognitive perspective can offerthe book also offers an overview of current research on cognition.The book provides detailed guidance for planning and carrying out CTA, with chapters on capturing knowledge and capturing the way people reason. It discusses studying cognition in real-world settings and the challenges of rapidly changing technology. And it describes key issues in applying CTA findings in a variety of fields. Working Minds makes the methodology of CTA accessible and the skills involved attainable. (shrink)

In a modern, calculative world, the techniques of tracking are everywhere in the ascendant. Enhanced by algorithmic procedures and analytics, they have been incorporated into distributed network systems, augmented by new sensing and locationing technologies, and embedded into mobile devices, urban structures and environments. Simultaneously, new practices of tracking and sensing have emerged across the consumer, state and corporate sectors. These practices are amplified in the case of megacities as they strive to keep pace with rapid urban development. All movement (...) is subordinated to a condition of 'calculative mobilization’, whereby the urban realm is understood through the spatialization of algorithmic operations. And yet, due to their unique large- and multi-scaled accumulations of data-enhanced actors and their complex, stratified modes of proximity and interoperable relationality, the particular densities of megacities challenge conventional spatial formats of movement and positioning. This article offers new formats of analysis for these calculative practices and the agential and ontological status of the hybrid urban entities that they register and engender. It also offers new structuring principles and political orientations, which are particularly urgent as we witness the ascendance of 'Spatial Data Infrastructures’ that are often promoted as participatory and inclusive while remaining largely inaccessible, pursuing proprietary aims, and infused with the potential not only to protect and inform but also to violate.

From the Introduction: This inquiry is concerned with the themes of praxis and action in four philosophic movements: Marxism, existentialism, pragmatism, and analytic philosophy. It is rare that these four movements are considered in a single inquiry, for there are profound differences of emphasis, focus, terminology, and approach represented by these styles of thought. Many philosophers believe that similarities among these movements are superficial and that a close examination of them will reveal only hopelessly unbridgeable cleavages. While respecting the genuine (...) fundamental differences of these movements, this inquiry is undertaken in the spirit of showing that there are important common themes and motifs in what first appears to be a chaotic babble of voices. I intend to show that the concern with man as an agent has been a primary focal point of each of these movements and further that each contributes something permanent and important to our understanding of the nature and context of human activity.

This book offers students a philosophical introduction to the ethical foundations of business management. It combines lessons from Kant with virtue ethics and also touches upon additional approaches such as utilitarianism. At the core of the book lies the concept of the nexus of imperfect managerial duty: building and reinforcing the virtuous managerial team, engaging in reasoned discourse among all stakeholders, and diligently pursuing business responsibilities, including the creative efforts necessary for modern organizations. Case illustrations of these applications are presented (...) throughout the book, including chapter appendices. Ancillary videos, test and answer banks and sample syllabi are available online via the author’s website. (shrink)

Drawing freely and expertly from Continental and analytic traditions, Richard Bernstein examines a number of debates and controversies exemplified in the works of Gadamer, Habermas, Rorty, and Arendt. He argues that a "new conversation" is emerging about human rationality—a new understanding that emphasizes its practical character and has important ramifications both for thought and action.

In this paper I argue that resource allocation in publicly funded medical systems cannot be done using a purely substantive theory of justice, but must also involve procedural justice. I argue further that procedural justice requires institutions and that these must be “local” in a specific sense which I define. The argument rests on the informational constraints on any non-market method for allocating scarce resources among competing claims of need. However, I resist the identification of this normative account of local (...) justice with the actual approach to local decision-making taken within the UK National Health Service. I illustrate my argument with reference to the case of provision of In Vitro Fertilisation within the UK NHS. (shrink)

To Serve With Honor should be required reading for all members of the officer corps of the United States military. Beyond that, it should be made required reading for all United States military academies, ROTC and officer candidate programs. This treatise on military ethics goes a long way in bridging the gap between the military and society's understanding of the military's ethical dilemma. It is a must for the student of military affairs. International Social Science Review To Serve With Honor (...) is the first book by an American to focus on the validity of current standards of military ethics in more than a century. This thoughtful study begins with the premise that the military profession is qualitatively different from any other profession. Author Richard Gabriel uses this assumption to address such vital questions as What are the limits of military obedience? and When does a soldier have an obligation to resist the orders of his superiors?

This chapter talks about to my other self reflection and existentialism in dungeons dragons. The 3.5 Dungeon Master's Guide II sourcebook discusses player motivations such as these, recognizing that, for many, they are one of the main reasons to play DD. The actor plays a character that someone else has envisioned and written: a figment of someone else's imagination. The author's task looks at the other side of this coin: an author conceives of a world and characters, and then sees (...) how those characters will react to their circumstances. The very chapter owes its existence to one from whom the author learned that he had the capacity for courage and faith, to Lady Yui – to my other self. (shrink)

Few philosophers have been as widely misunderstood as Nietzsche. His detractors and followers alike have often fundamentally misinterpreted him, distorting his views and intentions and criticizing or celebrating him for reasons removed from the views he actually held. Now available in paper, Nietzsche assesses his place in European thought, concentrating upon his writings in the last decade of his productive life. Nietzsche emerges in this comprehensive study as a philosopher of considerable sophistication who diverged sharply from traditional and ordinary ways (...) of thinking, but whose criticism, departures, and alternative views and strategies deserve to be given the most serious attention by philosophers.

In After the Rights Revolution, Cass Sunstein confronts the ?Chicago? intellectual tradition on the effects of government regulation. While recognizing the many failures of regulation, Sunstein argues that most regulation serves a potentially useful purpose and that the courts can be relied on to correct the worst regulatory failures. He offers a dizzying array of prescriptions to ensure this outcome, many of which would appear to run afoul of clear congressional intent. In a more recent book, Breaking the Vicious Circle, (...) Stephen Breyer offers a different diagnosis. He sees health?safety?environmental regulation as essentially out of control because of the ?vicious circle? created by irrational and ineffective government responses to the public's concern about the risk of exposure to carcinogens. Breyer does not believe that this vicious circle of excessive and irrational regulation can be broken by the courts. Instead, he suggests the creation of an elite bureaucratic corps with the mission of proposing more effective and less costly approaches to controlling threats to human health. (shrink)

What we value, like, endorse, want, and prefer changes over the course of our lives. Richard Pettigrew presents a theory of rational decision making for agents who recognise that their values will change over time and whose decisions will affect those future times.

Orientalism and Religion offers us a timely discussion of the implications of contemporary post-colonial theory for the study of religion. Drawing on a variety of post-structuralist and post-colonial thinkers, including Foucault, Gadamer, Said, and Spivak, Richard King examines the way in which notions such as mysticism, religion, Hinduism and Buddhism are taken for granted, and shows us how religion needs to be redescribed along the lines of cultural studies.

The discussion of good and evil must not be confined to the sterile lecture halls of academics but related instead to ordinary human feelings, needs, and desires, says noted philosopher Richard Taylor. Efforts to understand morality by exploring human reason will always fail because we are creatures of desire as well. All morality arises from our intense and inescapable longing. The distinction between good and evil is always clouded by rationalists who convert the real problems of ethics into complex (...) philosophical puzzles. In the first part of Good and Evil, Taylor looks for a more meaningful conception by reexamining and rejecting the whole rationalistic tradition that dominates philosophical ethics. The second part provides an empirical explanation of good and evil, noting that one does not have to look too far to find prime examples of the failure of fixed moral rules. Including important commentary on Joseph Fletcher's groundbreaking situation ethics, and Aristotle's virtues (e.g., magnanimity and pride), Taylor rounds out the book by developing a philosophy of aspiration--personal worth as an ethical ideal--to replace the morality of duty. He offers a modified form of situation ethics to fit the contemporary problems we face. (shrink)

This article outlines how the international push for inclusive education cannot be aligned with current education systems centred on neoliberal ideals of individualism, measurement, and competition. The way that these systems are organised means that a proportion of (usually marginalised) students are necessarily excluded. In order to meaningfully address the global education crisis, that sees millions of children and young people either out of school or unengaged with learning, this ontological misalignment must be acknowledged, and discourse and engagement around it (...) must be promoted. Drawing from the work of Donella Meadows, I argue that ‘high leverage points’ (information flows, rules, system goals, mindsets) are crucial places to intervene in education systems. Intervention at such points, while challenging, has the potential to lead to transformational and sustainable change; change that current ‘low leverage point’ initiatives fail to produce. I conclude with a call for further discourse and research into an examination of ‘high leverage points’ within education systems, how they interact, and how the development of an associated framework would be beneficial for researchers and development partners.

ABSTRACT This article argues that the data presented in Philosophy Within Its Proper Bounds are of greater interest to psychologists than to philosophers, and cautions experimental philosophers against some experimental shortcomings in the use of self-report and vignettes.

We conceive the development of photography along a horizontal axis: the camera mounted on a tripod, the lens looking out at the expanse of the earth. Cinematographic narrative is based on this horizontal gaze. But quite early on the recording device was transported vertically into the air: Militarized vision, with its own specific narrative mode, begins when the images from above are assembled into a database and analyzed to reveal movements, in order to predict their most probable future course. The (...) aim is to track certain objects, to target then, to destroy them. The arrival of computers and networked communications permits the accelerated development of a form of vision entirely devoted to these processes of tracking and targeting, which no longer offer images for our specular reflection a form of vision which is no longer «for us. ».

Ducklings were placed either singly or in pairs on a platform at two different heights. Both height and pairing influenced performance: More ducklings descended from the platform at low heights, and more single ducklings descended than paired ducklings. The social factor, pairing, made behavior more cautious and decreased the number of distress calls. A similar trend for pairing to influence performance was shown on the visual cliff. Without its peers, the duckling is a distressed animal. Previous careless behavior by ducklings (...) on the visual cliff may be ascribed to testing the ducklings outside their normal social environment. (shrink)

This is the third edition of a classic book first published in 1960, which has sold thousands of copies in two paperback edition and has been translated into several foreign languages. Popkin's work ha generated innumerable citations, and remains a valuable stimulus to current historical research. In this updated version, he has revised and expanded throughout, and has added three new chapters, one on Savonarola, one on Henry More and Ralph Cudworth, and one on Pascal. This authoritative treatment of the (...) theme of scepticism and its historical impact will appeal to scholars and students of early modern history now as much as ever. (shrink)

Conditionalization is one of the central norms of Bayesian epistemology. But there are a number of competing formulations, and a number of arguments that purport to establish it. In this paper, I explore which formulations of the norm are supported by which arguments. In their standard formulations, each of the arguments I consider here depends on the same assumption, which I call Deterministic Updating. I will investigate whether it is possible to amend these arguments so that they no longer depend (...) on it. As I show, whether this is possible depends on the formulation of the norm under consideration. (shrink)

The book begins with an overview that introduces the Theorem and the issues surrounding it, and explores how the essays that follow contribute to our understanding of those issues.

According to certain normative theories in epistemology, rationality requires us to be logically omniscient. Yet this prescription clashes with our ordinary judgments of rationality. How should we resolve this tension? In this paper, I focus particularly on the logical omniscience requirement in Bayesian epistemology. Building on a key insight by Hacking :311–325, 1967), I develop a version of Bayesianism that permits logical ignorance. This includes: an account of the synchronic norms that govern a logically ignorant individual at any given time; (...) an account of how we reduce our logical ignorance by learning logical facts and how we should update our credences in response to such evidence; and an account of when logical ignorance is irrational and when it isn’t. At the end, I explain why the requirement of logical omniscience remains true of ideal agents with no computational, processing, or storage limitations. (shrink)
