Effect of solute on the growth rate and the constitutional undercooling ahead of the advancing interface during solidification of an alloy and the implications for nucleation

A framework is presented for modeling the nucleation in the constitutionally supercooled liquid ahead of the advancing solid/liquid interface. The effects of temperature gradient, imposed velocity, slope of liquidus, and initial concentration have been taken into account in this model by considering the effect of interface retardation, which is caused by solute buildup at the interface. Furthermore, the effect of solute concentration on the chemical driving force for nucleation has been considered in this model. The model is used for describing the nucleation of Al-Si and Al-Cu alloys. It was found that the solute of Si has a significant impact on the chemical driving force for nucleation in AI-Si alloys whereas Cu has almost no effect in Al-Cu alloys.

The Constitutional (In)Validity of Religious Vilification Laws: Implications for Their Interpretation

A study is conducted to determine whether religious vilification laws are contrary to the implied freedom of political communication affirmed in the High Court's decision in Lange v Australian Broadcasting Corporation. He feels that to the extent that religious vilification laws are interpreted with principles, they are likely to leave sufficient place for freedom of religious discussion that happens to be relevantly political, at the same time the implied freedom of political means that the prohibitions imposed by religious vilification laws need to be interpreted narrowly and the exceptions construed widely, in order to leave room for political communication.

Will you tolerate this? The impact of affective commitment on complaint intention and postrecovery behavior

Successful complaint management primarily depends on customers' willingness to voice their complaints and on companies' ability to adequately deal with these complaints. This article investigates the impact of one relationship characteristic in the complaint management process: affective commitment. Based on two studies, the authors investigate whether affective commitment moderates the impact of complaint barriers on complaint intention (a) and whether it moderates the link between complaint satisfaction and purchase behavior after the complaint (b). Results show that affectively committed customers exhibit higher complaint intention irrespective of the level of complaint barriers. Furthermore, affectively committed customers display little change in their postrecovery behavior, even after a service failure followed by an unsatisfactory recovery attempt. It seems that these customers are tolerant and want to help the provider improve their business. Affective commitment seems to amplify willingness to help the company by means of voicing dissatisfaction despite considerable efforts in doing so. Moreover, affective commitment buffers the negative effects of service failures on postrecovery behavior. Findings have important implications for managers. They highlight the necessity to measure customers' affective commitment. Based on that, tailored complaint systems can be designed, which help in achieving a more effective allocation of resources for customer recovery.

Satisfaction with complaint handling:a replication study on its determinants in a business-to-business context

Research on the drivers of satisfaction with complaint handling (SATCOM) underlines the importance of procedural, relational, and interactional justice (Orsingher, Valentini, & de Angelis, 2010). Since these SATCOM-studies are largely conducted in business-to-consumer (B2C) markets, it is unclear what drives SATCOM in business-to-business (B2B) markets. Therefore, we replicate the justice model in an industrial context and find significant differences for procedural justice and interactional justice but not for distributive justice. While distributive justice is equally important in both contexts, procedural justice is more important in B2B markets whereas interactional justice drives SATCOM only in B2C markets. © 2013 Elsevier B.V.

Constitutional patriotism, migration and the post-national dilemma

This article addresses the challenges of justifying restrictions on migration given a rejection of nationalism as a defensible mode of political integration. Specifically, it focuses on constitutional patriotism, which is proposed as a means of making robust democratic practice possible in diverse contexts. Given that constitutional patriotism represents a commitment to universal principles as a source of attachment rather than the binding sentiment of nationalism, can we continue to rely on nationally defined and controlled migration practices? This article argues that, appropriately understood, constitutional patriotism implies a commitment to much freer movement of individuals across political boundaries than theorists have previously acknowledged. Applying such an approach, however, provokes some challenges to the sustainability of shared rule informed by principles rather than identity. This seeming paradox may mean that constitutional patriotism is more difficult to implement, and highlights practical challenges surrounding the liberalisation of border controls that are pertinent to theorists concerned with post-national citizenship more broadly conceived.

Redefining 'media' using a 'media-as-a-constitutional-component' concept:an evaluation of the need for the European Court of Human Rights to alter its understanding of 'media' within a new media landscape

This paper considers the impact of new media on freedom of expression and media freedom within the context of the European Convention on Human Rights and European Court of Human Rights jurisprudence. Through comparative analysis of US jurisprudence and scholarship, this paper deals with the following three issues. First, it explores the traditional purpose of the media, and how media freedom, as opposed to freedom of expression, has been subject to privileged protection, within an ECHR context at least. Secondly, it considers the emergence of new media, and how it can be differentiated from the traditional media. Finally, it analyses the philosophical justifications for freedom of expression, and how they enable a workable definition of the media based upon the concept of the media-as-a-constitutional-component.

CONSTITUTIONAL JUSTICE IN AFRICA: An Examination of Constitutional Positivism, Fundamental Law and Rights in Ghana and Nigeria

This work explores the idea of constitutional justice in Africa with a focus on constitutional interpretation in Ghana and Nigeria. The objective is to develop a theory of constitutional interpretation based upon a conception of law that allows the existing constitutions of Ghana and Nigeria to be construed by the courts as law in a manner that best serves the collective wellbeing of the people. The project involves an examination of both legal theory and substantive constitutional law. The theoretical argument will be applied to show how a proper understanding of the ideals of the rule of law and constitutionalism in Ghana and Nigeria necessitate the conclusion that socio-economic rights in those countries are constitutionally protected and judicially enforceable. The thesis argues that this conclusion follows from a general claim that constitutions should represent a ‘fundamental law’ and must be construed as an aspirational moral ideal for the common good of the people. The argument is essentially about the inherent character of ‘legality’ or the ‘rule of law.’ It weaves together ideas developed by Lon Fuller, Ronald Dworkin, T.R.S. Allan and David Dyzenhaus, as well as the strand of common law constitutionalism associated with Sir Edward Coke, to develop a moral sense of ‘law’ that transcends the confines of positive or explicit law while remaining inherently ‘legal’ as opposed to purely moral or political. What emerges is an unwritten fundamental law of reason located between pure morality or natural law on the one hand and strict, explicit, or positive law on the other. It is argued that this fundamental law is, or should be, the basis of constitutional interpretation, especially in transitional democracies like Ghana and Nigeria, and that it grounds constitutional protection for socio-economic rights. Equipped with this theory of law, courts in developing African countries like Ghana and Nigeria will be in a better position to contribute towards developing a real sense of constitutional justice for Africa.

Judicial Impartiality and Independence in Divided Societies: An Empirical Analysis of the Constitutional Court of Bosnia-Herzegovina

The role of Constitutional Courts in deeply divided societies is complicated by the danger that the salient societal cleavages may influence judicial decision-making and, consequently, undermine judicial independence and impartiality. With reference to the decisions of the Constitutional Court of Bosnia-Herzegovina, this article investigates the influence of ethno-nationalism on judicial behaviour and the extent to which variation in judicial tenure amplifies or dampens that influence. Based on a statistical analysis of an original dataset of the Court’s decisions, we find that the judges do in fact divide predictably along ethno-national lines, at least in certain types of cases, and that these divisions cannot be reduced to a residual loyalty to their appointing political parties. Contrary to some theoretical expectations, however, we find that long-term tenure does little to dampen the influence of ethno-nationalism on judicial behaviour. Moreover, our findings suggest that the longer a judge serves on the Court the more ethno-national affiliation seems to influence her decision-making. We conclude by considering how alternative arrangements for the selection and tenure of judges might help to ameliorate this problem.
