Contrary to assumptions that changes in brain networks are possible only during crucial periods of development, research in the past decade has supported the idea of a permanently plastic brain. Novel experience, altered afferent input due to environmental changes and learning new skills are now recognized as modulators of brain function and underlying neuroanatomic circuitry. Given findings in experiments with animals and the recent discovery of increases in gray and white matter in the adult human brain as a result of (...) learning, the old concept of cognitive reserve, that is the ability to reinforce brain volume in crucial areas and thus provide a greater threshold for age-dependent deficits, has been reinforced. The challenge we face is to unravel the exact nature of the dynamic structural alterations and, ultimately, to be able to use this knowledge for disease management. Understanding normative changes in brain structure that occur as a result of environmental changes and demands is pivotal to understanding the characteristic ability of the brain to adapt. (shrink)

Originally published in 1968. Scepticism is generally regarded as a position which, if correct, would be disastrous for our everyday and scientific beliefs. According to this view, a sceptical argument is one that leads to the intuitively false conclusion that we cannot know anything. But there is another, much neglected and more radical form of scepticism, Pyrrhonism, which neither denies nor accepts the possibility of knowledge and is to be regarded not as a philosophical position so much as the expression (...) of a philosophical way of life. Professor Naess argues that, given a sympathetic interpretation, Sextus Empiricus’s outline of Pyrrhonian scepticism provides the essentials of a genuine and rational sceptical point of view. He begins with a brief account of Pyrrhonism, then goes on to argue for the psychological possibility of this kind of scepticism, defending it against common objections, and examining some of its implications. The last two chapters provide detailed support for the rationality of Pyrrhonism, drawing mainly on certain methodological distinctions in semantics which both justify the Pyrrhonist’s failure to make assertions and restrict the scope of recent epistemological arguments against scepticism in such a way as to modify severely the conclusions based on them.

In einem auf drei Bände angelegten Dokumentationswerk werden Entstehung und Ausbreitung des Paracelsismus in den kontroversen Verflechtungen der Wissenschafts-, Literatur- und Sozialgeschichte des späten 16. Jahrhunderts verankert. Die kritische Edition aufschlußreicher, oft in unbekanntes Terrain führender Texte ist begleitet von umfangreichen Kommentaren sowie von biographischen Darstellungen der Urheber, Adressaten, Gegner bzw. Sympathisanten der paracelsistischen Reform und Protestbewegung. Der zweite Band des »Corpus Paracelsisticum« erschließt das weitläufige Oeuvre von Michael Toxites und Gerhard Dorn, wirkmächtige Gründergestalten des oberrheinischen Paracelsismus. Von da aus (...) fällt der Blick quer über die Konfessionsgrenzen auf andere kulturelle Zentren in Bayern, Sachsen, Schlesien, Böhmen und am Niederrhein. Mit Verfassern wie G. Fedro, M. Ambrosius, L. Span, B. Flöter, G. Etschenreutter, B. Scultetus, P. Perna, Th. Zwinger und J. Albrecht eröffnet sich ein epochaler, äußerst weitläufiger Diskurszusammenhang. In ihm lassen sich doxographische, methodische, hermeneutische, sprachtheoretische und überlieferungsspezifische Auseinandersetzungen ebenso beobachten wie Tendenzen einer theosophischen Spiritualisierung und heterodoxen Aufladung der in Paracelsus' Namen entwickelten Anthropologie und Kosmologie. Direkte Verbindungen ergeben sich unter anderem zu führenden Vertretern der sogenannten Schwenckfelder, damit auch zu Fraktionen aktiver protestantischer Dissidenten. Der Band wird neben dem weiterführenden Kommentar begleitet von einer ausführlichen Einleitung und erschlossen nicht nur durch mehrere Register, sondern auch durch wissenschaftshistorische Zusammenfassungen zu jedem Autorcorpus.

There is an international deep ecology social movement with key terms, slogans, and rhetorical use of language comparable to what we find in other activist “alternative” movements today. Some supporters of the movement partake in academic philosophy and have developed or at least suggested philosophies, “ecosophies,” inspired by the movement. R. A. Watson does not distinguish sufficiently between the movement and the philosophical expressions with academic pretensions. As a result, he falsely concludes that deep ecology implies setting man apart from (...) nature-a kind of “anthropocentrism” in his terminology: humans and only humans have no right to interfere with natural processes. What the deep ecology movement insists on is rather that life on Earth has intrinsic value and that human behavior should and must change drastically-and soon. (shrink)

Despite a strong sensitization to the corruption problem and a large body of interdisciplinary research, scientists have only rarely investigated which motivational, volitional, emotional, and cognitive components make decision makers in companies act corruptly. Thus, we examined how their interrelation leads to corruption by proposing an action model. We tested the model using a business simulation game with students as participants. Results of the PLS structural equation modeling showed that both an attitude and subjective norm favoring corruption led to a (...) desire to act corruptly. Given high perceived behavioral control, this desire was transformed into an intention that finally resulted in corrupt action. Components related to general private and professional goals did not allow for any prediction. Based on these results, we discuss preventative measures and methods for combating intra- and inter-organizational corruption. (shrink)

In this paper we discuss an approach called grounded action cognition, which aims to provide a theory of the interdependencies between motor control and action-related cognitive processes, like perceiving an action or thinking about an action. The theory contrasts with traditional views in cognitive science in that it motivates an understanding of cognition as embodied, through application of Barsalou’s general idea of grounded cognition. To guide further research towards an appropriate theory of grounded action cognition we distinguish between grounding qua (...) acquisition and grounding qua constitution. On this basis, we distinguish three possible theoretical conceptions of grounded action cognition. In addition to these methodological and conceptual analyses, we draw on recent empirical evidence to motivate our inclination towards a particular theory. According to this theory certain representations are involved in action cognition and action perception that are not modality-specific as usually proposed by advocates of grounded cognition. Further, the evidence is in favor of our more specific theory stating that for some cognitive abilities, some motor abilites are constitutive. (shrink)

When the social relevance of robotic applications is addressed today, the use of assistive technology in care settings is almost always the first example. So-called care robots are presented as a solution to the nursing crisis, despite doubts about their technological readiness and the lack of concrete usage scenarios in everyday nursing practice. We inquire into this interconnection of social robotics and care. We show how both are made available for each other in three arenas: innovation policy, care organization, and (...) robotic engineering. First, we analyze the discursive “logics” of care robotics within European innovation policy, second, we disclose how care robotics is encountering a historically grown conflict within health care organization, and third we show how care scenarios are being used in robotic engineering. From this diagnosis, we derive a threefold critique of robotics in healthcare, which calls attention to the politics, historicity, and social situatedness of care robotics in elderly care. (shrink)

Eventually, Kuhlmann proposes a dispositional trope ontology, according to which particularized properties and not things are the most basic entities.

_In Perception, Empathy, and Judgment_ Arne Johan Vetlesen focuses on the indispensable role of emotion, especially the faculty of empathy, in morality. He contends that moral conduct is severely threatened once empathy is prevented from taking part in an interplay with cognitive faculties in acts of moral perception and judgment. Drawing on developmental psychology, especially British "object relations" theory, to illuminate the nature and functioning of empathy, Vetlesen shows how moral performance is constituted by a sequence involving perception, judgment, (...) and action, with an interplay between the agent's emotional and cognitive faculties occurring at each stage. In the powerful tradition from Kant to present-day theorists such as Kohlberg, Rawls, and Habermas, reason is privileged over feeling and judgment over perception, in such a way that basic philosophical questions remain unasked. Vetlesen focuses our attention on these questions and challenges the long-standing assertion that emotions are damaging to moral response. In the final chapter he relates his argument to recent feminist critiques that have also castigated moral theorists in the Kantian tradition for their refusal to recognize a role for emotion in morality. While the book's argument is philosophical, its method and scope are interdisciplinary. In addition to critiques of such philosophers as Arendt, MacIntyre, and Habermas, it contains discussions of specific historical, ideological, and sociological factors that may cause "numbing"—selective or broad-ranging, pathological insensitivity—in humans. The Nazis' mass killing of Jews is studied to illuminate these and other relevant empirical aspects of large-scale immoral action. (shrink)

Recent theoretical and empirical work in cognitive science and neuroscience is brought into contact with the concept of the flow experience. After a brief exposition of brain function, the explicit–implicit distinction is applied to the effortless information processing that is so characteristic of the flow state. The explicit system is associated with the higher cognitive functions of the frontal lobe and medial temporal lobe structures and has evolved to increase cognitive flexibility. In contrast, the implicit system is associated with the (...) skill-based knowledge supported primarily by the basal ganglia and has the advantage of being more efficient. From the analysis of this flexibility/efficiency trade-off emerges a thesis that identifies the flow state as a period during which a highly practiced skill that is represented in the implicit system’s knowledge base is implemented without interference from the explicit system. It is proposed that a necessary prerequisite to the experience of flow is a state of transient hypofrontality that enables the temporary suppression of the analytical and meta-conscious capacities of the explicit system. Examining sensory-motor integration skills that seem to typify flow such as athletic performance, writing, and free-jazz improvisation, the new framework clarifies how this concept relates to creativity and opens new avenues of research.

Dass man eine musikalische Form auberschaubaro - und nicht etwa auberhorbaro - nennt, mutet ebenso selbstverstandlich an wie der immer wieder formulierte Vergleich zwischen Musik und Architektur.

In spite of the analogies between Q p and F p ((t)) which became evident through the work of Ax and Kochen, an adaptation of the complete recursive axiom system given by them for Q p to the case of F p ((t)) does not render a complete axiom system. We show the independence of elementary properties which express the action of additive polynomials as maps on F p ((t)). We formulate an elementary property expressing this action and show that (...) it holds for all maximal valued fields. We also derive an example of a rather simple immediate valued function field over a henselian defectless ground field which is not a henselian rational function field. This example is of special interest in connection with the open problem of local uniformization in positive characteristic. (shrink)

§1. Introduction.The motivation of this work comes from two different directions: infinite abelian groups, and ordered algebraic structures. A challenging problem in both cases is that of classification. In the first case, it is known for example (cf. [KA]) that the classification of abelian torsion groups amounts to that of reducedp-groups by numerical invariants called theUlm invariants(given by Ulm in [U]). Ulm's theorem was later generalized by P. Hill to the class of totally projective groups. As to the second case, (...) let us consider for instance the class of divisible ordered abelian groups. These may be viewed as ordered ℚ-vector spaces. Their theory being unstable, we cannot hope to classify them by numerical invariants. On the other hand, being o-minimal, the theory enjoys several good model theoretic properties (cf. [P-S]), so the search for some reasonable invariants is well motivated. The common denominator of the two cases, as well as of many others, is valuation theory. Indeed given an ordered vector space, one can consider it as a valued vector space, endowed with the natural valuation. Also, the socleG[p] of a reduced abelianp-groupG, endowed with the height functionhG, is a valued vector space over(the prime field of characteristicp) with values in the ordinals (cf. [F]).

We investigate the application of Courcelle’s theorem and the logspace version of Elberfeld et al. in the context of non-monotonic reasoning. Here we formalize the implication problem for propositional sets of formulas, the extension existence problem for default logic, the expansion existence problem for autoepistemic logic, the circumscriptive inference problem, as well as the abduction problem in monadic second order logic and thereby obtain fixed-parameter time and space efficient algorithms for these problems. On the other hand, we exhibit, for each (...) of the above problems, families of instances of a very simple structure that, for a wide range of different parameterizations, do not have efficient fixed-parameter algorithms (even in the sense of the large class XPnu, resp., XLnu) under standard complexity assumptions.

Ecologically responsible policies are concerned only in part with pollution and resource depletion. There are deeper concerns which touch upon principles of diversity, complexity, autonomy, decentralization, symbiosis, egalitarianism, and classlessness.

Advocates of the New Mechanicism in philosophy of science argue that scientific explanation often consists in describing mechanisms responsible for natural phenomena. Despite its successes, one might think that this approach does not square with the ontological strictures of quantum mechanics. New Mechanists suppose that mechanisms are composed of objects with definite properties, which are interconnected via local causal interactions. Quantum mechanics calls these suppositions into question. Since mechanisms are hierarchical it appears that even macroscopic mechanisms must supervene on a (...) set of “objects” that behave non-classically. In this paper we argue, in part by appeal to the theory of quantum decoherence, that the universal validity of quantum mechanics does not undermine neo-mechanistic ontological and explanatory claims as they occur within in classical domains. Additionally, we argue that by relaxation of certain classical assumptions, mechanistic explanatory strategies can sometimes be carried over into the quantum domain. (shrink)

Evil is a poorly understood phenomenon. In this provocative 2005 book, Professor Vetlesen argues that to do evil is to intentionally inflict pain on another human being, against his or her will, and causing serious and foreseeable harm. Vetlesen investigates why and in what sort of circumstances such a desire arises, and how it is channeled, or exploited, into collective evildoing. He argues that such evildoing, pitting whole groups against each other, springs from a combination of character, situation, and social (...) structure. By combining a philosophical approach inspired by Hannah Arendt, a psychological approach inspired by C. Fred Alford and a sociological approach inspired by Zygmunt Bauman, and bringing these to bear on the Holocaust and ethnic cleansing in the former Yugoslavia, Vetlesen shows how closely perpetrators, victims, and bystanders interact, and how aspects of human agency are recognized, denied, and projected by different agents.

Covering a period from the Middle Ages through the 1990s, and addressing phenomena overlooked by Rokkan such as statebuilding and nationalism, this book demonstrates that Rokkan's models continue to be relevant to modern political science and sociology. Kommisrud's study is a valuable contribution to Rokkanian approaches and the understanding of Eastern European development within the historical and geographic context of Europe as a whole.

Many consumers implicitly associate sustainability with lower product strength. This so-called ethical = less strong intuition (ELSI) poses a major threat for the success of sustainable products. This article explores this pervasive lay theory and examines whether it is a key barrier for sustainable consumption patterns. Even more importantly, little is known about the underlying mechanisms that might operate differently at the implicit and explicit levels of the consumer’s decision-making. To fill this gap, three studies examine how the implicit judgments (...) that consumers activate automatically shape their consumption behaviors, in concert with their more controlled explicit beliefs about sustainable products. The Main Study investigates the ELSI’s imprint on actual shopping patterns and disentangles the implicit and explicit mechanisms of the lay theory. This paper also asks how this negative influence can be attenuated by examining whether the consumer’s interest in sustainable consumption reduces reliance on the ELSI. Two follow-up studies confirm the robustness from different methodological and practical perspectives. Implications for companies and policy makers are derived. (shrink)

Die Gesundheitsreformen der vergangenen Jahrzehnte haben die Organisation Krankenhaus einem grundlegenden Wandel unterzogen. Neben offenkundig notwendigen und sinnvollen Veränderungen hat es aber auch solche gegeben, die die Frage aufwerfen, welchen gesellschaftlichen Aufgaben das Krankenhaus in Zukunft dienen soll. Pointiert gefragt: Welcher Effektivität soll die seit Jahren betriebene Effizienzsteigerung in der Organisation Krankenhaus dienen außer der Begrenzung eines allgemeinen Kostenanstiegs? Es ergibt sich ein paradoxer Befund: Der Wandel der Organisation Krankenhaus scheint sich maßgeblich der Ökonomisierung zu verdanken, die zugleich das Mittel (...) darstellt, mit dem der Wandel bewältigt werden soll. In diesem Beitrag werden organisations- und institutionstheoretische Entwicklungen auf den Prozess der Ökonomisierung abgebildet und aus einer ethischen Perspektive reflektiert. (shrink)

Peter Reed has defended the basis for an environmental ethic based upon feelings of awe for nature together with an existentialist absolute gulf between humans and nature. In so doing, he has claimed that there are serious difficulties with Ecosophy T and the terms, Self-realization and identification with nature. I distinguish between discussions of ultimate norms and the penultimate deep ecology platform. I also clarify and defend a technical use of identification and attempt to show that awe and identification may (...) be compatible concepts. (shrink)

The Snowden leaks, first published in June 2013, provided unprecedented insights into the operations of state-corporate surveillance, highlighting the extent to which everyday communication is integrated into an extensive regime of control that relies on the ‘datafication’ of social life. Whilst such data-driven forms of governance have significant implications for citizenship and society, resistance to surveillance in the wake of the Snowden leaks has predominantly centred on techno-legal responses relating to the development and use of encryption and policy advocacy around (...) privacy and data protection. Based on in-depth interviews with a range of social justice activists, we argue that there is a significant level of ambiguity around this kind of anti-surveillance resistance in relation to broader activist practices, and critical responses to the Snowden leaks have been confined within particular expert communities. Introducing the notion of ‘data justice’, we therefore go on to make the case that resistance to surveillance needs to be conceptualized on terms that can address the implications of this data-driven form of governance in relation to broader social justice agendas. Such an approach is needed, we suggest, in light of a shift to surveillance capitalism in which the collection, use and analysis of our data increasingly comes to shape the opportunities and possibilities available to us and the kind of society we live in.

ArgumentGerman twentieth-century history is characterized by stark changes in the political system and the momentous consequences of World Wars I and II. However, instead of uncovering specific kinds or periods of “Kaiserreich science,” “Weimar science,” or “Nazi science” together with their public manifestations and in such a way observing a narrow link between popular science and political orders, this paper tries to exhibit some remarkable stability and continuity in popular science on a longer scale. Thanks to the rich German history (...) of scientific leadership in many fields, broad initiatives for science popularization, and a population and economy open to scientific progress, the media offered particularly rich popular science content, which was diversified for various audiences and interests. Closer consideration of the format, genre, quality, and quantity of popular science, and of the uses and value audiences attributed to it, along with their respective evolution, reveals infrastructures underpinning science communication. Rather than dealing with specific discourses, the conditions of science communication are at the center of this article. Therefore I focus on the institutions, rules, laws, and economies related to popular science, as well as on the philosophical, moral, and national propositions related to it, and also on the interactions among this ensemble of rather heterogeneous elements. This approach allows a machinery of popular scientific knowledge to be identified, in Foucauldian terms adispositif, one which is of a particularly cultural nature. (shrink)
