We present a model of computation for string functions over single-sorted, total algebraic structures and study some basic features of a general theory of computability within this framework. Our concept generalizes the Blum-Shub-Smale setting of computability over the reals and other rings. By dealing with strings of arbitrary length instead of tuples of fixed length, some suppositions of deeper results within former approaches to generalized recursion theory become superfluous. Moreover, this gives the basis for introducing computational complexity in a BSS-like (...) manner. Relationships both to classical computability and to Friedman's concept of eds computability are established. Two kinds of nondeterminism as well as several variants of recognizability are investigated with respect to interdependencies on each other and on properties of the underlying structures. For structures of finite signatures, there are universal programs with the usual characteristics. For the general case of not necessarily finite signature, this subject will be studied in a separate, forthcoming paper. (shrink)

In this book, Peter Wenz addresses the major issues and thinkers in environmental ethics. His style is accessible, even journalistic at times, featuring current facts, real controversies, and a vivid narrative, while preserving rigorous philosophical content.theories and methods are introduced, not for their own sake, but to help the reader understand and solve environmental problems.

Three facts are widely thought to be key to the characterization of human cognitive uniqueness (though a number of other factors are often cited as well): (a) humans are sophisticated cultural learners; (b) humans often rely on mental states with rich representational contents; and (c) humans have the ability and disposition to make and use tools. This article argues that (a)–(c) create a positive feedback loop: Sophisticated cultural learning makes possible the manufacture of tools that increase the sophistication of representational (...) decision-making, which in turn allows for yet further increases in the sophistication of cultural learning and tool manufacture.

Recent research has detailed the use of neuroscience in several jurisdictions, but Australia remains a notable omission. To fill this substantial void we performed a systematic review of neuroscience in Australian criminal cases. The first section of this article reports the results of our review by detailing the purposes for which neuroscience is admitted into Australian criminal courts. We found that neuroscience is being admitted pre-trial, at trial, and during sentencing. In the second section, we evaluate these applications. We generally (...) found that courts admit neuroscience cautiously, and to supplement more well-established forms of evidence. Still, we found some instances in which the court seemed to misunderstand the neuroscience. These cases ranged from interpreting neuroscience as “objective” evidence to admitting neuroscience when the same non-neuroscientific psychiatric evidence would be inadmissible for being common sense. Furthermore, in some cases, neuroscientific evidence presents a double-edged sword; it may serve to either aggravate or mitigate a sentence. Thus, the decision about whether or not to tender this evidence is risky. (shrink)

This book is the first general introduction to the theological and philosophical writings of Aḥmad al-Aḥsāʾī and Kāẓim ar-Ra sh tī, the founders of the Sh ay kh iyya, and ʿAlī-Muḥammad Shīrāzī , the initiator of the Bābiyyah.

En este artículo explico una parte de la labor de G. K. Chesterton como crítico económico: su crítica al sistema capitalista. Con la imagen de la locura (loco sería, no el incapacitado para razonar, sino el que vive fuera de la realidad), considera al capitalismo como una locura porque su discurso es coherente pero no ofrece una vida digna para el ser humano: el capitalismo quita la libertad al proletario, le obliga a desvincularse espiritualmente de su propiedad y le desalienta (...) cuando propone alternativas económicas. Desarrollo también cómo otros autores coinciden con Chesterton, con críticas parecidas. (shrink)

This book explores the author's intellectual journey from an upbringing in Reform Judaism to a deep engagement with science, which they initially believed would answer the ultimate questions of existence. Raised with a secular view of God, the author sought to replace religious explanations with scientific ones, expecting that modern theories like Relativity and Quantum Mechanics would clarify the mysteries of the universe. However, through their studies, they discovered that science also leaves many profound questions unanswered, especially about the origins (...) of the universe and the nature of consciousness and free will. Although the author remains an atheist, they are humbled by the realization that their secular worldview is, in many ways, a form of faith, no more fully justified than religious belief. This book is a reflection on their shifting perspective, exploring the limits of both science and religion in answering life's deepest questions. (shrink)

Dynamic stability of the knee and weakness of the extensor muscles are considered to be the most important functional limitations after anterior cruciate ligament injury, probably due to changes at the central level of motor control rather than at the peripheral level. Despite general technological advances, fewer contraindicative surgical procedures, and extensive postoperative rehabilitation, up to 65% of patients fail to return to their preinjury level of sports, and only half were able to return to competitive sport. Later, it becomes (...) clear that current rehabilitation after knee surgery is not sufficient to address the functional limitations after ACL reconstruction even years after surgery. Therefore, new therapeutic tools targeting the central neural system, i.e., the higher centers of motor control, should be investigated and integrated into current rehabilitation practice. To improve motor performance when overt movement cannot be fully performed, several techniques have been developed to increase physical and mental activation without the need to perform overt movements. Among the most popular cognitive techniques used to increase physical performance are motor imagery and action observation practices. This review, which examines the available evidence, presents the underlying mechanisms of the efficacy of cognitive interventions and provides guidelines for their use at home. (shrink)

The origin of novel traits is what draws many to evolutionary biology, yet our understanding of the mechanisms that underlie the genesis of novelty remains limited. Here I review definitions of novelty including its relationship to homology. I then discuss how ontogenetic perspectives may allow us to move beyond current roadblocks in our understanding of the mechanics of innovation. Specifically, I explore the roles of canalization, plasticity and threshold responses during development in generating a reservoir of cryptic genetic variation free (...) to drift and accumulate in natural populations. Environmental or genetic perturbations that exceed the buffering capacity of development can then release this variation, and, through evolution by genetic accommodation, result in rapid diversification, recurrence of lost phenotypes as well as the origins of novel features. I conclude that, in our quest to understand the nature of innovation, the nature of development deserves to take center stage. BioEssays 30:432–447, 2008. © 2008 Wiley Periodicals, Inc. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 8.2 (2003) 106-125 [Access article in PDF] Leopold's NovelThe Land Ethic in Barbara Kingsolver's Prodigal Summer Peter S. Wenz Introduction Like many good novels, Prodigal Summer's 1 account of love, tragedy, conflict, and choice in human relationships conveys an overall message about how life should be lived. In this case the message corresponds to Aldo Leopold's call for "a land ethic [that] changes the (...) role of Homo sapiens from conqueror of the land-community to plain member and citizen of it." People should "respect... fellow-members and also... the community as such." 2 Barbara Kingsolver explains Leopold's key ideas and updates the Land Ethic by showing how it might guide people today. The present paper selectively displays this relationship, and then suggests some pedagogical advantages of fiction.Prodigal Summer tells three interconnected stories that take place from May through July one year in contemporary rural Kentucky. One story features Deanna Wolfe, who has spent the last 25 months working for the U.S. Forest Service in a wilderness area on Zebulon Mountain where she restores trails and impedes illegal hunting. She has just discovered that coyotes have arrived, but so has Eddie Bondo, a handsome man from the West who hates coyotes because they sometimes kill livestock. [End Page 106]Another story features Lusa Landowski and her husband Cole Widener. Lusa is an entomologist who taught at the University of Kentucky before marrying Cole and moving to his family's tobacco farm that adjoins the national forest where Deanna works. Cole dies early in the novel and Lusa tries to save the family farm.Finally, Nannie Rawley is a senior citizen who grows organic apples nearby and has conflicts with her more senior neighbor, Garnett Walker, who wants to kill weeds with chemicals to keep his property looking neat. Garnett's goal is to cross-fertilize chestnut trees to create an American chestnut that is immune to chestnut blight. Ecocentrism, Hunting, the Biotic Pyramid, and Exotic Species Aldo Leopold's Land Ethic is famously holistic and ecocentric. The ecosystem, a holistic entity, has value over and above, and in most cases more than, the value of its individual components. This ecocentric perspective is summed up in the maxim: "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise" (1970, 262).Ecocentrism explains Leopold's attitude toward hunting. In many passages, such as the October account of hunting ruffed grouse (58-62) and partridge (62-69), Leopold describes the hunt with approval. However, he disapproves of programs to eradicate keystone predators because their elimination impoverishes ecosystems. His classic account, "Thinking Like a Mountain," concerns wolf eradication. He writes, "I thought that because fewer wolves meant more deer, that no wolves would mean hunters' paradise" (138). But he found that wolf eradication harms mountains, that is, ecosystems. I have watched the face of many a newly wolfless mountain, and seen the south-facing slopes wrinkle with a maze of new deer trails. I have seen every edible bush and seedling browsed, first to anaemic desuetude, and then to death. I have seen every edible tree defoliated to the height of a saddle horn.... In the end the starved bones of the hoped-for deer herd, dead of its own too-much, bleach with the bones of the dead sage, or molder under the high-lined junipers. (139-40) Leopold's concept of a biotic pyramid explains why wolf eradication harms ecosystems. According to Leopold, the energy that plants absorb from the sun: [End Page 107]... flows through a circuit called the biota, which may be represented by a pyramid consisting of layers. The bottom layer is the soil. A plant layer rests on the soil, an insect layer on the plants, a bird and rodent layer on the insects, and so on up through the various animal groups to the apex layer, which consists of the larger carnivores.... Proceeding upward, each successive layer decreases in numerical... (shrink)

In the wake of the emergence and rapid development of nanoethics there swiftly followed fundamental criticism: nanoethics was said to have become much too involved with speculative developments and was concerning itself too little with actually pending questions of nanotechnology design and applications. If this diagnosis is true, then large parts of nanoethics are misguided. Such fundamental criticism must surely either result in a radical reorientation of nanoethics or be refuted for good reasons. In this paper, I will examine the (...) critics’ central arguments and, building on this scrutiny, formulate an answer to these alternatives. The results lead to conclusions which allow explaining and unfolding the thesis of this paper that instead of speculative nanoethics we should better speak of and develop explorative philosophy of nanotechnology.

The aim of the paper is to present and evaluate Bolzano's theory of grounding, that is, his theory of the concept expressed and the relation brought into play by 'because'. In the first part of the paper (Sections 1-4) the concept of grounding is distinguished from and related to three other concepts: the concept of an epistemic reason}, the concept of causality, and the concept of deducibility (i.e., logical consequence). In its second part (Sections 5-7) Bolzano's positive account of grounding (...) is reconstructed in axiomatic form and critically discussed. (shrink)

Business schools have become implicated in the widespread demonisation of the financial classes. By educating those held most responsible for the crisis – financial traders and speculators – they are said to have produced ruthlessly talented graduates who have ambition in abundance but little sense for social responsibility or ethics. This ethical lack thrives upon the trading floor within a compelling critique of the complicity of the pedagogy of the business school with the financial crisis of the global economy. An (...) ethical turn within the curriculum is now widely encouraged as a counteractive force. Within this paper, however, we argue that taking this ethical turn is not enough. For business ethicists to learn from the financial crisis, the crisis' legacy needs to be taken account of, and financialisation needs to be taken seriously. Pedagogical reform cannot bracket itself off from the crisis as if it were coincidental with or separate from it. Post-crisis pedagogy must rather take the fact that it is requested now, in light of the crisis, as its very point of departure. The financial crisis must not be understood as something to be resisted in the name of Business Ethics. Instead, the financial crisis must be understood as the very foundation for contemporary Business Ethics in particular and for contemporary business and management education more generally. (shrink)

Propositional logic has been recognized throughout the centuries as one of the cornerstones of reasoning in philosophy and mathematics. Over time, its formalization into Boolean algebra was accompanied by the recognition that a wide range of combinatorial problems can be expressed as propositional satisfiability (SAT) problems. Because of this dual role, SAT developed into a mature, multi-faceted scientific discipline, and from the earliest days of computing a search was underway to discover how to solve SAT problems in an automated fashion. (...) This book, the Handbook of Satisfiability, is the second, updated and revised edition of the book first published in 2009 under the same name. The handbook aims to capture the full breadth and depth of SAT and to bring together significant progress and advances in automated solving. Topics covered span practical and theoretical research on SAT and its applications and include search algorithms, heuristics, analysis of algorithms, hard instances, randomized formulae, problem encodings, industrial applications, solvers, simplifiers, tools, case studies and empirical results. SAT is interpreted in a broad sense, so as well as propositional satisfiability, there are chapters covering the domain of quantified Boolean formulae (QBF), constraints programming techniques (CSP) for word-level problems and their propositional encoding, and satisfiability modulo theories (SMT). An extensive bibliography completes each chapter. This second edition of the handbook will be of interest to researchers, graduate students, final-year undergraduates, and practitioners using or contributing to SAT, and will provide both an inspiration and a rich resource for their work. Edmund Clarke, 2007 ACM Turing Award Recipient: "SAT solving is a key technology for 21st century computer science." Donald Knuth, 1974 ACM Turing Award Recipient: "SAT is evidently a killer app, because it is key to the solution of so many other problems." Stephen Cook, 1982 ACM Turing Award Recipient: "The SAT problem is at the core of arguably the most fundamental question in computer science: What makes a problem hard?". (shrink)

Kaum ein anderer Begriff wird unterschiedlicher, ja gegensätzlicher verwendet als der Gottesbegriff. Nicht immer behaupten Gläubige, was Atheisten leugnen, und nicht immer bestreiten Atheisten, wozu sich Gläubige bekennen. Diese radikale Umstrittenheit des Gottesbegriffs stellt die Frage nach dem "wahren Antlitz Gottes", nach dem Verständnis dessen, was das Wort "Gott" wirklich bedeutet. Laesst sich überhaupt nachvollziehbar benennen, was dieses Wort meint, oder entzieht sich seine Bedeutung nicht jedem menschlichen Verstäendnis? Was heisst es denn, wenn wir sagen, Gott sei Person, allmächtig, allwissend, (...) gätig, dreifaltig? Worauf müssen wir achten, wenn wir über Gott reden, damit wir uns nichts vormachen? Das Buch hilft zu erkennen, auf welchen Gottesbegriff Verlass ist, so dass wir unser Leben darauf setzen können. (shrink)

BALLESTEROS, Jesús: «Domeñar las finanzas, cuidar de la naturaleza».

Der Band gibt erstmals einen umfassenden Überblick über den lyrischen Nachlass des jungen Nietzsche aus den 1850er und -60er Jahren. Zusätzlich präsentiert Armin Thomas Müller eine Beispiel-Edition und historisch kontextualisierende Analyse des Manuskripthefts Mp I 22 von 1858. Somit trägt der Band grundlegend zur literatur-, philosophie- wie kulturgeschichtlichen Auseinandersetzung mit Nietzsche bei. Armin Thomas Müllers Arbeit nimmt den bislang in der literaturwissenschaftlichen wie auch philosophischen Auseinandersetzung mit Friedrich Nietzsche vernachlässigten lyrischen Nachlass aus der Zeit zwischen 1850 und 1869 (...) in den Blick. Anschließend an eine grundlegende Einführung in das Thema wird Nietzsches Jugendlyrik überblicksartig vorgestellt mit Schwerpunkten zur Editions- und Forschungsgeschichte, zu literaturgeschichtlichen Kontexten sowie zu den autoreflexiven Aufzeichnungen des jungen Nietzsche, die das Thema (lyrischer) Dichtung umkreisen. Die vorliegende Publikation enthält zudem eines heutigen materialorientierten Standards entsprechende Faksimile-Edition mit diplomatischer Transkription des Manuskripthefts Mp I 22 von 1858. Das kulturgeschichtliche Erkenntnispotenzial in Nietzsches Jugendgedichten wird abschließend in einer textgenetischen und historisch kontextualisierenden Analyse der edierten lyrischen Texte aus Mp I 22 deutlich. Auf dieser Grundlagenforschung werden weiterführende Auseinandersetzungen mit Nietzsche aufbauen können. (shrink)

Parallel to the public discussion on the benefits and risks of nanotechnology, a debate on the ethics of nanotechnology has begun. It has been postulated that a new “nano-ethics” is necessary. In this debate, the — positive as well as negative — visionary and speculative innovations which are brought into connection with nanotechnology stand in the foreground. In this contribution, an attempt is made to discover new ethical aspects of nanotechnology in a more systematic manner than has been the case. (...) It turns out that there are hardly any completely new ethical aspects raised by nanotechnology. It is much rather primarily a case of gradual shifts of emphasis and of relevance in questions which, in principle, are already known and which give reason for ethical discussions on nanotechnology. In a certain manner, structurally novel ethical aspects arise through the important role played by visions in the public discourse. New questions are also posed by the fact that previously separate lines of ethical reflection converge in the field of nanotechnology. The proposal of an independent “nano-ethics”, however, seems exaggerated. (shrink)

Notions of democracy and nationhood constitute the pivotal legacy of the American Revolution, but to understand their development one must move beyond a purely American context. Citizens of a Common Intellectual Homeland explores the simultaneous emergence of modern concepts of democracy and the nation on both sides of the Atlantic during the age of revolutions. Armin Mattes argues that in their origin the two concepts were indistinguishable because they arose from a common revolutionary impulse directed against the prevailing hierarchical (...) political and social order. The author shows how the reconceptualization of democracy and the nation, which resulted from this revolutionary impulse, received its decisive form from the French Revolution. Although the French Revolution was instrumental in redefining the two terms, however, neither were these changes confined to France, nor did the new meanings merely radiate from France to other countries. To illustrate the transatlantic emergence of these ideas, Mattes considers the works of pairs of prominent intellectual contemporaries--one in America and the other in Europe--each writing on a common topic. The thinkers and topics include Thomas Paine and Edmund Burke on the transatlantic revolutions, John Adams and Friedrich von Gentz on the mixed constitution, James Madison and Immanuel Kant on perpetual peace, and Thomas Jefferson and Destutt de Tracy on the nation. Mattes's approach highlights the significant impact that the French Revolution had on the evolution of thought in the period, demonstrating that the emergence and early development of modern concepts of democracy and the nation in America were intimately tied to revolutionary events and processes in the larger Atlantic world.

A recent trend in economics has been to appeal to evolutionary theory when addressing various open questions in the subject. I here further investigate one particular such appeal to evolutionary biology: the argument that, since markets select firms as coherent units, firms should be seen to be genuine economic agents. To assess this argument, I present a model of firm/office selection in a competitive market, and show that there are cases where markets can select for firms/offices as collective units – (...) and thus, as agents of their own – but also that there are cases where they do not. In this way, I try to make the evolutionary argument for the agency-based view of the firm more precise. (shrink)
