Polymer Fluid Dynamics: Continuum and Molecular Appoaches

To solve problems in polymer fluid dynamics, one needs the equation of continuity, motion, and energy. The last two equations contain the stress tensor and the heat-flux vector for the material. There are two ways to formulate the stress tensor: (1) one can write a continuum expression for the stress tensor in terms of kinematic tensors, or (2) one can select a molecular model that represents the polymer molecule, and then develop an expression for the stress tensor from kinetic theory. The advantage of the kinetic theory approach is that one gets information about the relation between the molecular structure of the polymers and the rheological properties. In this review, we restrict the discussion primarily to the simplest stress tensor expressions or “constitutive equations” containing from two to four adjustable parameters, although we do indicate how these formulations may be extended to give more complicated expressions. We also explore how these simplest expressions are recovered as special cases of a more general framework, the Oldroyd 8-constant model. The virtue of studying the simplest models is that we can discover some general notions as to which types of empiricisms or which types of molecular models seem to be worth investigating further. We also explore equivalences between continuum and molecular approaches. We restrict the discussion to several types of simple flows, such as shearing flows and extensional flows. These are the flows that are of greatest importance in industrial operations. Furthermore, if these simple flows cannot be well described by continuum or molecular models, then it is not necessary to lavish time and energy to apply them to more complex flow problems.

O conceito de Klugheit em Kant

This paper aims to analyze Kant’s concept of Klugheit and how it relates to morality. For Kant, this concept does not belong to the field of morality as it is, according to him, an interested act, therefore only capable of hypothetical imperatives. In this sense, prudence generates at most one’s own happiness, but not necessarily goodness. On the other hand, we reason that prudence plays an important role in promoting man’s moral improvement towards the exercise of virtue. Prudence only holds good, therefore, if understood from a Kantian anthropological point of view.

Subsidiarity between Law and Economics. Research Papers in Law, 1/2005

From the Introduction. The present contribution is an attempt to raise awareness between the 'trenches' by juxtaposing the two approaches to subsidiarity. Subsequently, I shall set out why, in economics, subsidiarity is embraced as a key principle in the design and working of the Union and how a functional subsidiarity test can be derived from this thinking. Throughout the paper, a range of illustrations and examples is provided in an attempt to show the practical applicability of a subsidiarity test. This does not mean, of course, that the application of the test can automatically "solve" all debates on whether subsidiarity is (not) violated. What it does mean, however, is that a careful methodology can be a significant help to e.g. national parliaments and the Brussels circuit, in particular, to discourage careless politicisation as much as possible and to render assessments of subsidiarity comparable throughout the Union. The latter virtue should be of interest to national parliaments in cooperating, within just six weeks, about a common stance in the case of a suspected violation of the principle. The structure of the paper is as follows. Section 2 gives a flavour of very different approaches and appreciation of the subsidiarity principle in European law and in the economics of multi-tier government. Section 3 elaborates on the economics of multi-tier government as a special instance of cost / benefit analysis of (de)centralisation in the three public economic functions of any government system. This culminates in a five-steps subsidiarity test and a brief discussion about its proper and improper application. Section 4 applies the test in a non-technical fashion to a range of issues of the "efficiency function" (i.e. allocation and markets) of the EU. After showing that the functional logic of subsidiarity may require liberalisation to be accompanied by various degrees of centralisation, a number of fairly detailed illustrations of how to deal with subsidiarity in the EU is provided. One illustration is about how the subsidiarity logic is misused by protagonists (labour in the internal market). A slightly different but frequently encountered aspect consists in the refusal to recognize that the EU (that is, some form of centralisation) offers a better solution than 25 national ones. A third range of issues, where the functional logic of subsidiarity could be useful, emerges when the boundaries of national competences are shifting due to more intense cross-border flows and developments. Other subsections are devoted to Union public goods and to the question whether the subsidiarity test might trace instances of EU decentralisation: a partial or complete shift of a policy or regulation to Member States. The paper refrains from an analysis of the application of the subsidiarity test to the other two public functions, namely, equity and macro-economic stabilisation.2 Section 5 argues that the use of a well-developed methodology of a functional subsidiarity test would be most useful for the national parliaments and even more so for their cooperation in case of a suspected violation of subsidiarity. Section 6 concludes.

Decentralisation of EC Competition Law Enforcement and General Principles of Community Law. Research Papers in Law, 4/2004

From the Introduction. By virtue of Council Regulation No. 1/2003, as of 1st May 2004 the full application of EC competition law will be entrusted to national competition authorities (hereinafter NCAs) and national courts. The bold reform of EC competition law enforcement adheres to the system of executive federalism1 which characterises the EC legal system. The repartition of competences within the Community allocates implementation of Community law mainly at Member States level. Pursuant to Article 10 EC, they are responsible for the implementation of the measures which have been adopted at Community level for the achievement of the objectives specified in the EC Treaty. Consequently, the attainment of the Community objectives depends very much upon the cooperation of national authorities, which act in accordance with their own national procedural rules.2 The various national procedural rules present themselves as conduits through which Community law is implemented and enforced. While as a rule Community law is not designed to alter national procedural rules, the Community legal order cannot afford to leave national procedural rules untouched when they are liable to hamper the effective application of Community law....For reason of space, this contribution intends only to highlight some aspects of Regulation No. 1/2003 with regard to which general principles of Community law are able to condition national procedural rules.

The European Union’s Democratic Deficit and Options for EU Democracy in the 21st Century. EU Centre Singapore Working Paper No. 22, August 2014

The European Union (EU) is widely acknowledged as a successful example of economic and political integration of nation states today – a slate of democratic institutions such as the European Parliament have also been developed and European citizens now possess extensive political and civil rights by virtue of the introduction of European citizenship. Nevertheless, the EU is said to suffer from a so called “democratic deficit” even as it seeks deeper and closer integration. Decades of institutional design and elite closed-door decisions has taken its toll on the inclusion and integration of European citizens in social and political life, with widening socio-economic inequalities and the resurgence of extreme-right parties during in the wake of the debt crisis in the Eurozone. This paper attempts to evaluate the democratic development of the EU through the use of a process-oriented approach, and concludes at the end with discussions on the various options that the EU and its citizens can take to reform democratic processes and institutions in Europe.

Tugend, Recht und Moral: Tendenzen der Verantwortungszuschreibung

The attribution of responsibility in world society is increasingly a field of contestation. On the one hand, the perceptions of far-reaching causal and moral links between spatially and temporally distant events are ever more explicitly pronounced; on the other hand, the very complexity of these links often engenders a fragmentation of responsibility in law as well as in moral commitment. Identifying three competing conceptualisations of responsibility, namely a turn to virtue ethics, processes of juridification, and processes of moralisation, this article explores their different temporal and social dimensions, and the effects they each have on the relation between those held responsible and those affected by the situation that is to be accounted for.
