Fifty years ago Hartman studied the barrier transmission time of wave packets (J Appl Phys 33:3427–3433, 1962). He was inspired by the tunneling experiments across thin insulating layers at that time. For opaque barriers he calculated faster than light propagation and a transmission time independent of barrier length, which is called the Hartman effect. A faster than light (FTL or superluminal) wave packet velocity was deduced in analog tunneling experiments with microwaves and with infrared light thirty years later. Recently, the (...) conjectured zero time of electron tunneling was claimed to have been observed in ionizing helium inside the barrier. The calculated and measured short tunneling time arises at the barrier front. This tunneling time was found to be universal for elastic fields as well as for electromagnetic fields. Remarkable is that the delay time is the same for the reflected and the transmitted waves in the case of symmetric barriers. Several theoretical physicists predicted this strange nature of the tunneling process. However, even with this background many members of the physics community do not accept a FTL signal velocity interpretation of the experimental tunneling results. Instead a luminal front velocity was calculated to explain the FTL experimental results frequently. However, Brillouin stated in his book on wave propagation and group velocity that the front velocity is given by the group velocity of wave packets in the case of physical signals, which have only finite frequency bandwidths. Some studies assumed barriers to be cavities and the observed tunneling time does represent the cavity lifetime. We are going to discus these continuing misleading interpretations, which are found in journals and in textbooks till today. (shrink)

This book recovers Aristotle's understanding of the roles of rhetoric and prudence in public leadership, comparing it to the other major political theories of leadership: utilitarianism, as advocated by J.S. Mill, and duty-ethics, as advocated by Immanuel Kant.

English summary: The relationship between science and politics can hardly be reduced to a simple formula. On one hand they appear to be completely separate systems that follow only their own internal logic. On the other hand, mutual references can be identified. It is quite possible to consistently align political decisions to scientific evidence, whereby the autonomy and the legitimacy of democratic policy would however inevitably be affected. In four sections the relationship between science and politics are analyzed under the (...) viewpoint of a specific key question: Does true policy require powerful decision and therefor specifically the absence of science? And is science not conversely determined by it being free of value and policy? What about concepts that tend to want to replace policy with science? Finally, there is the question of what legitimate role science can play in today's politics, and whether this can be in the form of policy advice. This book, with contributions from renowned authors from different disciplines, is systematically devoted to answering these questions. German text. German description: Das Verhaltnis zwischen Wissenschaft und Politik ist kaum auf eine einfache Formel zu bringen. Einerseits erscheinen sie als vollig getrennte Systeme, die nur ihrer eigenen inneren Logik folgen. Andererseits lassen sich wechselseitige Bezugnahmen ausmachen. So ist durchaus denkbar, politische Entscheidungen konsequent an wissenschaftlichen Erkenntnissen auszurichten, wodurch aber unweigerlich die Autonomie auch und gerade demokratisch legitimierter Politik betroffen wuerde.In vier Sektionen wird das Verhaltnis von Wissenschaft und Politik unter einer bestimmten Leitfrage analysiert: Setzt wahre Politik kraftvolle Dezision und somit gerade die Abwesenheit von Wissenschaft voraus? Und ist Wissenschaft nicht umgekehrt durch ihre Wert- und damit Politikfreiheit bestimmt? Wie steht es um Konzepte, die Politik tendenziell durch Wissenschaft ersetzen wollen? Schliesslich fragt sich, welche legitime Rolle Wissenschaft heutzutage in der Politik spielen kann, etwa in Form der Politikberatung.Der Band mit Beitragen renommierter Autoren unterschiedlicher Disziplinen geht diesen Problemkonstellationen in systematischer Weise nach.

At the beginning of the year, the Draft Common Frame of Reference (DCFR) was published. The text is the result of the work of a broad range of private law scholars from the Member States of the European Union, and it presents itself as an ‘academic’ document, committed to the precepts of scholarship rather than politics. Notwithstanding its unwieldy name, the text is nothing less than the draft of the central components of a European Civil Code. The following article aims (...) to inform the reader about this potentially important document and to initiate further academic debate about it. Following an overview of the genesis and content of the DCFR (Part 1), the discussion focuses on whether, and to what extent, it is based upon consistent and convincing core aims and values (Part 2). The article then proceeds to address, more specifically, the significance of private autonomy, and it examines the extent to which the proposed rules satisfy the requirements of legal certainty and legal clarity (Part 3). Thereafter, the DCFR is measured against the criteria of internal consistency and systematic integrity (Part 4). Also (Part 5) the question is asked whether the Draft critically reflects and convincingly integrates the sources on which it is based (that is the Lando Commission's Principles of European Contract Law and the Acquis Principles, as well as the private law traditions of the Member States). Also deserving of attention is the inclusion of more than 120 definitions of central concepts of private law, which are not to be found in this form or level of detail in either the Lando Principles or the national private laws (Part 6).

In almost all countries, the transition from a centrally planned economy to a market economy caused high unemployment. The governments attempted to ease the changeover to a market economy for the unemployed by introducing several passive and active labour market policies. This paper first points out which effects were to be expected of such policies from the perspective of Austrian Economics. These theoretical hypotheses are then tested empirically. It turns out that the hypotheses deducted from Austrian Economics theory are impressively (...) corroborated by the empirical evidence.Dans presque tous les pays, la transition d’une économie centralement planifiée vers une économie de marché ont provoqué un chômage élevé. Les gouvernements ont essayé d’adoucir la transition vers une économie de marché pour les chômeurs en introduisant plusieurs politiques passives et actives sur le marché du travail. Tout d’abord, cet article souligne quels étaient les effets attendus de telles politiques à la lumière de l’économie autrichienne. Ces hypothèses théoriques sont ensuite testées de manière empirique. Il en ressort que les hypothèses déduites de la théorie économique autrichienne sont corroborées de manière significative par les preuves empiriques. (shrink)

It is difficult to translate the title “Wissen und Glauben” into English, because there is a debate between Kant, Jacobi, Fichte and Hegel behind it. Through Fichtes “Wissenschaftslehre” knowledge has been accepted as the basic element of all scholarship, whereas faith belongs to religion.First of all we will show, that knowledge and faith have an independent root. Each can exist by itself whithout the other one. Secondly, we will show how they complement one another. In fact faith can be sufficient (...) for the individual without knowledge. But faith can only achieve its richness and its public effectiveness together with knowledge, the πλήρωμα of faith needs knowledge. Knowledge on the other hand can neither take its depth nor reach its totality without faith. Knowledge that wants to enlighten itself must rely on faith. Faith shows knowledge that it is neither fully founded on man nor can it be fully considered as an image of the universe. On the one hand faith is criticism of self-empowered knowledge, on the other hand it is the way to surpass knowledge and to complete it. (shrink)

Many virtue epistemologists conceive of epistemic competence on the model of skill —such as archery, playing baseball, or chess. In this paper, I argue that this is a mistake: epistemic competences and skills are crucially and relevantly different kinds of capacities. This, I suggest, undermines the popular attempt to understand epistemic normativity as a mere special case of the sort of normativity familiar from skilful action. In fact, as I argue further, epistemic competences resemble virtues rather than skills—a claim that (...) is based on an important, but often overlooked, difference between virtue and skill. The upshot is that virtue epistemology should indeed be based on virtue, not on skill. (shrink)

This book challenges the standard view that modern hermeneutics begins with Friedrich Ast and Friedrich Schleiermacher, arguing instead that it is the dialectic of reflective and teleological reason in Kant’s Critique of Judgment that provides the actual proto-hermeneutic foundation. It is revolutionary in doing so by replacing interpretive truth claims by the more appropriate claim of rendering opaque contexts intelligible. Taking Gadamer’s comprehensive analysis of hermeneutics in Truth and Method (1960) as its point of departure, the book turns to Kant’s (...) Critiques, reviewing his major concepts as a coherent system in relation to his sensus communis. At the heart of the book is the interaction between reflective, bottom-up search and teleological, top-down interpretative projection as provided in Part II of the third Critique. This text contends that Kant’s broad definition of nature invites the liberation of the reflective-teleological judgment from its biological exemplifications and so permits us to establish its generalised status as a path-breaking, methodological tool. Kant’s dialectic of reflective search and meaning bestowing, stipulated teleology is asserted to anticipate a series of motifs commonly associated with hermeneutics. Figures covered include Dilthey, Husserl, Ingarden, Heidegger, Gadamer, Apel, Habermas, Ricoeur, Derrida, Foucault, Lyotard, Deleuze, Vattimo, Nancy and Caputo. Their collective contributions to interpretation allow for a review of the evolution of hermeneutics from the perspective of the Kantian critique of the limitations of human cognition. The book is written for the informed, general reader, but will likewise appeal to advanced undergraduate and graduate students as well as researchers in the humanities and social sciences. (shrink)
