Few have done more than Martin Gutzwiller to clarify the connection between classical time-dependent motion and the time-independent states of quantum systems. Hence it seems appropriate to include the following discussion of the origins of the time-dependent Schrödinger equation in this volume dedicated to him.
The threshold law for N-body fragmentation under dipole forces is formulated. It emerges from the energy dependence of the normalization of the correlated continuum wave function for N fragments. It is shown that the dipole threshold law plays a key role in understanding all threshold fragmentation phenomena since it links the classical threshold law for long-range Coulomb interactions to the statistical law for short-range interactions. Furthermore, a tunnelling mechanism is identified as the common feature which occurs for all three classes (...) of interactions, short-range, dipole and Coulomb. (shrink)
This article examines the political perspective of corporate social responsibility from the standpoint of normative Islam. We argue that large firms within Muslim majority countries have the moral obligation to assist governments in addressing challenges related to sustainable socioeconomic development and in advancing human rights. In substantiating our argument, we draw upon the Islamic business ethics, stakeholder theory, and corporate governance literatures, as well as the concepts of Maqasid al Shariah and fard al ‘ayn versus fard al kifayah to introduce (...) a normative model elucidating critical Islamic precepts. Finally, we propose an Islamic “political” corporate governance framework, which democratizes firm decision making by embedding “core” stakeholders, nongovernmental organizations, and Shariah scholars in the corporate board, thereby enhancing the ability of businesses to respond to stakeholder concerns and priorities, while mitigating interstakeholder and intraboard power asymmetries.

New computer systems of discovery create a research program for logic and philosophy of science. These systems consist of inference rules and control knowledge that guide the discovery process. Their paths of discovery are influenced by the available data and the discovery steps coincide with the justification of results. The discovery process can be described in terms of fundamental concepts of artificial intelligence such as heuristic search, and can also be interpreted in terms of logic. The traditional distinction that places (...) studies of scientific discovery outside the philosophy of science, in psychology, sociology, or history, is no longer valid in view of the existence of computer systems of discovery. It becomes both reasonable and attractive to study the schemes of discovery in the same way as the criteria of justification were studied: empirically as facts, and logically as norms. (shrink)
This paper studies intentional action in stit logic. The formal logic study of intentional action appears to be new, since most logical studies of intention concern intention as a static mental state. In the formalization we distinguish three modes of acting: the objective level concerning the choices an agent objectively exercises, the subjective level concerning the choices an agent knows or believes to be exercising, and finally, the intentional level concerning the choices an agent intentionally exercises. Several axioms constraining the (...) relations between these different modes of acting will be considered and discussed. The side effect problem will be analyzed as an interaction between knowingly doing and intentionally doing. Non-successful action will be analyzed as a weakening of the epistemic attitude towards action. Finally, the notion of ‘attempt’ will be briefly considered as a further weakening in this direction.

The cosmological theory of the author, discussed in (Greben in Found Sci 15(2):153–176, 2010 ), has a number of implications for the interpretation of initial conditions and the fine-tuning problem as discussed by Vidal (Found Sci 15(4):375–393, 2010a ).
We discuss a new theory of the universe in which the vacuum energy is of classical origin and dominates the energy content of the universe. As usual, the Einstein equations determine the metric of the universe. However, the scale factor is controlled by total energy conservation in contrast to the practice in the Robertson–Walker formulation. This theory naturally leads to an explanation for the Big Bang and is not plagued by the horizon and cosmological constant problem. It naturally accommodates the (...) notion of dark energy and proposes a possible explanation for dark matter. It leads to a dual description of the universe, which is reminiscent of the dual theory proposed by Milne in 1937. On the one hand one can describe the universe in terms of the original Einstein coordinates in which the universe is expanding, on the other hand one can describe it in terms of co-moving coordinates which feature in measurements. In the latter representation the universe looks stationary and the age of the universe appears constant. The paper describes the evolution of this universe. It starts out in a classical state with perfect symmetry and zero entropy. Due to the vacuum metric the effective energy density is infinite at the beginning, but diminishes rapidly. Once it reaches the Planck energy density of elementary particles, the formation of particles can commence. Because of the quantum nature of creation and annihilation processes spatial and temporal inhomogeneities appear in the matter distributions, resulting in residual proton (neutron) and electron densities. Hence, quantum uncertainty plays an essential role in the creation of a diversified complex universe with increasing entropy. It thus seems that quantum fluctuations play a role in cosmology similar to that of random mutations in biology. Other analogies to biological principles, such as recapitulation, are also discussed.

Face to Face.Jan M. Broekman - 2009 - International Journal for the Semiotics of Law - Revue Internationale de Sémiotique Juridique 22 (1):45-59.details
Peirce shows how he presupposes that a ‘most general science of semeiotic’ is entirely a matter of culture. Semiotics unfolds even beyond the debate on specific differences between nature and culture. The expression ‘semiotics of culture’ entails all components of a true pleonasm. Pierce finds his parallel in the philosophy of Hegel and both philosophers consider the close ties between expressiveness and consciousness as a specifically human, cultural and spiritual activity. That viewpoint leads not only to linguistic but also to (...) other expressive phenomena, among which the body. Faces are perhaps the most outstanding bodily carriers of expression, so that Peirce’s analyses of Thirdness relate to the human face, not as a natural but as a cultural datum, in particular an artifice. A face-to-face relationship is embedded in a regulative discourse rather than an ethical appeal or other metaphysical dimensions. Three cases show various degrees of artificiality with different semiotic implications: Tilda Swinton’s appearance at the recent 2008 Oscar ceremony, the body art of Orlan and the first 2005 facial transplant of Isabelle Dinoire. The three do not only show how the human face is an artifice, but also how realities can appear to be fictitious within patterns of semiotic nature. Any sign can be a correlative to a fictitious world! (shrink)
The Roberta Kevelson Seminar on Law and Semiotics is integrated in the regular program of a US Law School and student enrollment is honored with credit points. Hitherto, the study of Legal Semiotics has mainly been located outside the Law Schools in the US and the Faculties of Law in the EU. Two important questions within the more general theme of Legal Semiotics and Legal Education arose: (1) the program requirements in an education context, and (2) the attention and interests (...) of the students. This IJSL issue offers essays presented during the Round Table which closed the Seminar, provides some experience-based suggestions for a Seminar program and discusses how to deal with the pragmatic attitude of law students. It interests how those topics relate to legal and semiotic literature and how they focus globally important viewpoints, as can be concluded in the example of the legal semiotics of family structures.

Lawyers write, blog and are otherwise producers of words; they structure public life through legal discourse and integrate all issues that reinforce legal reasoning. Even if one is inclined not to justify the power of their words in the context of a democratic theory, one is hardly able to challenge its public acceptance. But semiotic analyses harden the question whether these emperors wear nothing but robes. That attitude intensifies where medicine becomes increasingly relevant for legal discourse, as becomes clear where (...) for instance US political viewpoints bring bioethical issues to the Courts. One major theme in today’s medicine pertains to identity in its psychological, philosophical and social dimensions. Identity thus becomes a groundbreaking semiotic issue in law and medicine; both discourses are particular important to the otherness of the other. A US criminal law case interests here (Harrington v. State of Iowa, 2003; cited as: 659N.W.2d 509). The case is decided with “information about what the person has stored in his brain”. A chain of signs is involved: from “brain-function” to “brain-storage” via “brain-scan” to “brain-fingerprint”, for which the case became famous. A long series of signs and meanings belong here to intertwined discourses. Central is a particular sign in each discourse: “brain” means brain scan, and “fingerprint” means law! The two display trading mechanisms, which determine the otherness of the other and the self! The chain of signs in the Harrington case shows inter-disciplinarity in law and inter-discursivity among law and medicine. The trading itself underlines the semiotic dimensions in cyberspace, in particular the semiotics of the virtual (Hayles, Kurzweil) and their effects on legal discourse. (shrink)
Taking the letter of the law literally would equal the death of our hopeand expectation that law and its practices of justice will createimproved social realities. This insight is, however, seldom formulatedin legal discourse. A more profound analysis shows how ``the literal'',taken as a legal expression, covers the management of law's semanticsrather than delivering the precise description of a state of affairs inlaw. This pertains in particular to the ``well informed citizen'' (A.Schutz). Can legal meanings that should enter and perhaps (...) change thecitizen's life sphere for the better, transcend the boundaries of legaldiscourse by means of appealing to a literal meaning? (shrink)

The paper consists of two parts, outlined in the title.I. In the historical science time appears as an element of the historian’s workshop. The historian collects source information, evaluates them and assigns respective dates. Only on the ground of thus “processed” sources may he reproduce the past: events and longer development processes, setting them in time. This dated time is understood colloquially as something objective, which runs one way and may be measured.II. A historian who studies the past reality depends (...) on the extent to which those sources are preserved. As a result of their interpretation, with the use of increasingly excellent research methods, he reproduces that reality. He must carry out an ongoing selection of historical facts found. This exposes him to temptations of such selection of those facts so as to adjust the historical knowledge to serve well the national interests, his own political opinions, etc. In this way the historian exerts influence on social awareness, which may consists of various myths and stereotypes, which sometimes lead to negative social behaviors: aggression, chauvinism, etc. Therefore, for researcher honesty’s sake and in the sense of moral responsibility, he must be careful to be as impartial as possible in his work.

One vivid description of folktale research, still applicable although more than a half century old, reads, “Folktale study is like a desert journey, where the only landmarks are the bleached bones of earlier theories.” Because theories have proven to be so ephemeral in comparison with the tales themselves , it might seem prudent to place more stock in the tales and less in the theories or at least to take an eclectic approach toward theorizing so as to hedge bets; but (...) not all scholars of folktales exercise more circumspection now than their predecessors did fifty years ago. For example, in Little Red Riding Hood: A Casebook Alan Dundes — one of the most prominent American folklorists of our day — adduces no material dated from before 1697 that is related to the tale “Little Red Riding Hood” but manages nonetheless to question sharply the very notion of valuing early written evidence. By scrutinizing a short Latin poem written in the first quarter of the eleventh century, I hope to refute Dundes's dismissal of literary evidence and to underscore the pertinence of studying medieval literature in coming to grips with that beautiful and elusive phenomenon to which English-speakers give the name “fairy tale.”.
