The title I have chosen seems to signal a tension, even a contradiction, in a number of respects. Democracy appears to be a form of political organisation and government in which, through general and public participatory procedures, a sufficiently legitimate political will is formed which acquires the force of law. Justice, by contrast, appears to be a value external to this context which is not so much linked to procedures of “input” or “throughput” legitimation but is understood instead as an output- or outcome-oriented concept. At times, justice is even understood as an otherworldly idea which, when transported into the Platonic cave, merely causes trouble and ends up as an undemocratic elite project. In methodological terms, too, this difference is sometimes signalled in terms of a contrast between a form of “worldly” political thought and “abstract” and otherworldly philosophical reflection on justice. In my view, we are bound to talk past the issues to be discussed under the heading “transnational justice and democracy” unless we first root out false dichotomies such as the ones mentioned. My thesis will be that justice must be “secularised” or “grounded” both with regard to how we understand it and to its application to relations beyond the state.
Seit der Meiji-Zeit spielte die Germanistik unter den Fremdsprachenphilologien an japanischen Universitäten eine Sonderrolle. Von konservativen Politikern gefördert, um den aus England und Frankreich importieren demokratischen Ideen entgegenzuwirken (vgl. Naka 1998), konnte das Deutsche unter den zweiten Fremdsprachen bis in die jüngste Zeit seine führende Rolle behaupten. Inzwischen ist das Fach jedoch aus internen und externen Gründen in eine Krise geraten. Die seit der Nachkriegszeit mehrfach in Angriff genommene, aber erst seit Ende der 80er Jahre tatsächlich einsetzende Universitätsreform spielt dabei eine entscheidende Rolle. Es wird im folgenden darum gehen, die Germanistik innerhalb dieses wesentlich politisch bestimmten Feldes zu verorten. Ich werde zunächst einige Grundlinien der japanischen Universität in Erinnerung bringen, wie sie bis in die 80er Jahre hinein einigermaßen unbefragt galten, anschließend die Probleme skizzieren, die sich daraus ergaben und die Universitätsreform erläutern. Abschließend wird es um die Folgen für die Germanistik, die zweiten Fremdsprachen und das Deutsche gehen. Sämtliche Ausführungen beziehen sich, wenn nicht anders vermerkt, auf die staatlichen Universitäten. Die privaten Universitäten haben naturgemäß mehr Freiheiten bei der Gestaltung ihrer Studiengänge und spielen daher teilweise eine Vorreiterrolle. In Ausrichtung, Zielgruppe und finanziellen Möglichkeiten sind sie aber so unterschiedlich, daß sie nur schwer als Gruppe zu fassen sind. Dennoch ergeben sich Übereinstimmungen mit den staatlichen Universitäten, weil sie deren ökonomisches und demographisches Umfeld teilen. Zudem müssen sich auch die privaten Hochschulen an die Richtlinien des Erziehungsministeriums halten. Auch für sie gelten also die Grundlinien der Reformen, es müssen hier aber je nach Ausrichtung der Hochschule verschieden starke Abstriche gemacht werden.

In this thesis, laboratory investigations have been conducted to investigate several processes occurring during the melt segregation (crystal settling and compaction processes), as well as during emplacement of plutons. With the help of three different sets of centrifuge experiments rates of these three magmatic processes have been evaluated. In the first series of the centrifuge experiments, the diapiric ascent of buoyant material from two source layers at different depths was studied. Through five models, the hypothesis of ascending diapirs was tested and it was demonstrated whether a rising diapir ascends straight upward or if its ascent might be deviated by another buoyant, softer – and consequently easier to travel through – layer which is located within the overburden strata. We were interested under which conditions they can be formed. For this purpose we placed perturbations on top of both the buoyant layers; either with a set-off of both the protrusions (for three of these experiments), or with both protrusion sitting directly on top of each other (for one of the experiments). In the first experiment, we omitted the perturbations, to test which pathways diapirs take which grow from natural Rayleigh-Taylor instabilities. Three others experiments differed in the viscosity contrast between the overburden and the buoyant material. Through the experimental runs, the effects of different overburden viscosities and perturbation positions on the number of the diapirs were observed. The modeling results show that two diapirs rising from the offset perturbations do not take the same pathway through the overburden layer. Rather, each diapir takes a different pathway, with the deeper diapir piercing through its overburden while rising, regardless if it was a buoyant layer or denser overburden layers. However, when the two perturbations were situated directly above each other in the different PDMS layers, this resulted in the formation of one big diapir rather than several smaller ones, and the overburden layer was less deformed than with offset perturbations. Diapiric structures as those derived from the models without perturbation and where the perturbation are offset occur within Great Kavir Basin (Iran), where numerous salt diapirs grew from several salt horizons, which show a similar spatial distribution. The resulting structure observed in the model where the two perturbations situated directly above each other, is close to what is observed in composite batholiths such as the Flasergranitoid Zone within the Bergsträßer Odenwald Crystalline Complex (Germany). The second series of models were aimed to study crystal settling within a magma. For this purpose experiments with an artificial magma of 30 vol% olivine in 70 vol% basaltic melt were conducted to elucidate the formation mechanisms and time scales of gravitational cumulates. Through the experiments, two physical processes have been observed: (i) purely mechanical compaction, and (ii) chemical compaction induced by dissolution and re-precipitation of settled crystals. The results reveals that the mechanical settling of the dense olivine suspension occurs at about 1/6 the speed of simple Stokes settling, and a sedimentation exponent n of 4.1 is found. Evidences of chemical compaction induced by dissolution and re-precipitation of settled crystals have been highlighted by a detailed analysis of the fine structure of olivine grain boundaries. This last has revealed (1) the presence of Ca, which is characteristic only for MORB-melt, at the interface of two adjacent Ol-grains even when no melt is present; (2) a not fully crystallized boundary layer between two adjacent olivine grains. The crystal size distribution curves and the grain size growth exponent n ~3.6 indicate that diffusion controlled Ostwald ripening is the dominant crystal growth mechanism in concentrated magmatic suspensions. Finally, the formation times in natural olivine adcumulates have been calculated. The last series of centrifuge experiments deals with the crystal-melt settling-floating mechanism in a system composed of natural two pyroxene gabbro. The results have revealed a vertical evolution of the major and trace elements in the melt phase. Then, a numerical modelling of the sedimentation process of the crystals has been made in order to describe the compaction evolution with time. In comparing the numerical simulation with the centrifuge modelling, the stratification of the compacted layer in the runs is reproduced in numerical models. Moreover, on the base of the numerical and centrifuge modelling, a sedimentation exponent describing a deviation of settling in concentrated suspensions from Stokes sedimentation has been evaluated. Finally, the numerical simulation is applied to the Muskox intrusion to estimate the formation time and the melt fraction evolution in using the hindered sedimentation model calculations.
The energy dependence of the local and violation in Au+Au and Cu+Cu collisions in a large energy range is estimated within a simple phenomenological model. It is expected that at LHC the chiral magnetic effect will be about 20 times weaker than at RHIC. At lower energy range, covered by the low-energy scan at RHIC and future NICA/FAIR facilities, the created magnetic field strength and energy density of deconfined matter are rather high providing necessary conditions for the chiral magnetic effect. However, the particular model for the chiral magnetic effect predicts that this effect should vanish sharply at energy somewhere above the top SPS one. To elucidate CME background effects the Hadron-String-Dynamics (HSD) transport model including electromagnetic fields is put forward. Importance of new planning experiments at LHC and for the low-energy RHIC scan program is emphasized.
Der Text Konstitutive Regeln – normativ oder nicht? Ein Blick auf ihre Rolle in Praktiken geht der Frage nach, ob – und wenn ja, in welcher Weise – konstitutive Regeln normativ sind. Die Herausforderung besteht darin, dass diese Regeln bzw. ihre Befolgung womöglich durchweg in nicht-normativen Begriffen beschrieben werden können – nämlich im Wesentlichen als Erfüllung notwendiger und/oder hinreichender Bedingungen. Natürlich kann man, aus welchen Gründen auch immer, jederzeit fordern, einer konstitutiven Regel Folge zu leisten. Aber damit würde Normativität ‚von außen‘ an solche Regeln herangetragen; in Frage steht aber, ob diese Regeln selbst normativ sind. Für eine derartige ‚interne‘ Normativität spricht sicherlich unser Umgang mit diesen Regeln und auch unser alltägliches Reden über sie. So beschreiben wir in unserer Alltagspraxis etwa das Befolgen von Spielregeln (als Paradebeispiele für konstitutive Regeln) als etwas, das korrekt ist oder getan werden soll – und Abweichungen entsprechend als Verletzungen. Der Überlegungsgang des Textes ist zweigeteilt: In einem ersten Schritt werden einige Arten von konstitutiven Regeln unterschieden. Der systematische Ertrag dieser begrifflichen Überlegungen besteht in dem Vorschlag, dass manche Arten von konstitutiven Regeln ganz problemlos als auch normative Phänomene charakterisierbar sind, andere hingegen nicht. In einem zweiten Schritt wird vor allem zu zeigen versucht, dass einige der wirklichen ‚Problemfälle‘ konstitutiver Regeln zumindest als schwach-normative Regeln beschrieben werden können (im Unterschied zu stark-normativen Phänomenen wie Verpflichtungen oder Verbote). Die ‚schwache Normativität‘ dieser Regeln kommt zum Vorschein, wenn man ihre Rolle in Praktiken betrachtet – insbesondere die Art und Weise, wie sich Akteure in diesen Praktiken unter Berufung auf konstitutive Regeln kritisieren, ohne sich dabei bereits als verpflichtet zu behandeln, diese Regeln zu befolgen.
We examine the scaling trends in particle multiplicity and flow observables between SPS, RHIC and LHC, and discuss their compatibility with popular theoretical models. We examine the way scaling trends between SPS and RHIC are broken at LHC energies, and suggest experimental measurements which can further clarify the situation.
NCQ scaling of elliptic flow is studied in a non-equilibrium hadronization and freeze-out model from ideal, deconfined and chirally symmetric Quark Gluon Plasma (QGP), to final non-interacting hadrons. In this transition the quarks gain constituent quark mass while the background Bag-field breaks up. The constituent quarks then recombine into simplified hadron states, while chemical, thermal and flow equilibrium break down. Then the resulting temperatures and flow velocities of baryons and mesons will be different. In a simplified model, we reproduce the constituent quark number scaling.
We derive the equations of second order dissipative fluid dynamics from the relativistic Boltzmann equation following the method of W. Israel and J. M. Stewart [1]. We present a frame independent calculation of all first- and second-order terms and their coefficients using a linearised collision integral. Therefore, we restore all terms that were previously neglected in the original papers of W. Israel and J. M. Stewart.
