Simulations of the SCHOLAR scramjet experiment

The DDES method is employed to investigate the complex physics involved in supersonic combustion and in particular in the SCHOLAR scramjet test case. The influence on computational results of prescribing turbulent fluctuations at the entrance to the combustion chamber is investigated. The interaction of shock waves, vortices, turbulence and combustion is studied and the existence of secondary vortices on the upper will of the combustor is proposed. © 2012 by Peter Cocks.

The Application of the Crime against Humanity Category in Simon Ruling from Argentinean Supreme Court

En Argentine, la mise en place des lois internationales sur les droits humains dans les tribunaux locaux et son impact ne peuvent être séparés de l’histoire récente, qui a vu commettre des crimes massifs pendant la dictature de 1976 à 1983. En 1987, la Cour suprême a voté « la loi de l’Obéissance due » aussi appelée « loi de l’impunité ». Puis, en 2005, cette loi a été déclarée invalide par une nouvelle décision de la Cour suprême, car contraire à celles sur les droits humains. Les principes de la loi internationale ont prévalu pour permettre une justice efficace, ce changement soulignant le rôle de la société civile. Étant donné les réclamations grandissantes pour plus de justice dans la société argentine, le rôle de la société civile est essentiel pour comprendre la transformation et l’accroissement de la valeur normative des lois sur les droits humains dans les Cours suprêmes argentines. L’action de la société civile internationale est liée aux processus sud-américains de démocratisation, surtout dans le domaine des droits humains. La lutte contre l’impunité n’a été rendue publique que très récemment, soit seulement à partir de 2003. Elle se traduit aujourd’hui dans le rôle grandissant de l’expertise juridique et éthique dans la mise en place des politiques publiques. En fait, l’influence de la nouvelle stratégie dépend largement de la transparence des administrations bureaucratiques, des valeurs et de la volonté politique du gouvernement. Le changement légal peut être analysé selon l’acteur à l’origine du changement, le mécanisme par lequel le changement se fait et le contexte qui fournit l’opportunité pour ce changement. Dans le présent article, nous nous concentrons sur les stratégies argumentatives présentées par les juges dans la description des évènements entourant la décision de 2005. Le but de cet article est d’essayer de lier les stratégies des sociétés civiles avec l’argumentation légale dans la décision de 2005. Ces stratégies poussent à surmonter l’obstacle juridique : le fait que les crimes contre l’humanité n’étaient pas codifiés dans la loi nationale quand ils se sont déroulés (et ne le sont toujours pas.)

Explanations of the International Community Deadlock in Bosnia and Herzegovina

La Bosnie-Herzégovine est sous supervision internationale depuis 1995. Les principaux acteurs de cette communauté internationale soit l’Union Européenne (UE) et le Bureau du Haut-Représentant à la Communauté Internationale (OHR) ont exprimé à de nombreuses reprises leur intention de transformer la mission internationale en s’éloignant du pouvoir discrétionnaire du OHR en le remplaçant par la perspective d’intégration offerte par l’UE. Malgré les bonnes intentions, cette transition semble être dans une impasse. Depuis 2006, l’organisation et la distribution des responsabilités au sein de la communauté internationale sont restées inchangées. Ce mémoire s’intéresse à ces deux principaux acteurs et à leur rôle dans l’impasse. L’objectif est de tester trois cadres d’analyse soit le rationalisme, le constructivisme et la complexité des régimes pouvant expliquer cette impasse. En se basant sur des interviews avec des experts et des représentants des deux institutions, ce mémoire explore dans quelle mesure et dans quels contextes chaque cadre d’analyse est apte à expliquer le comportement des acteurs.

Functionalism, co-operation, good faith, and the making of the "daily-preventive justice" in contract law theory and practice. A contribution to a rational understanding of good faith and to its future reseasonable developments. Evaluations from

The thoughts and observations contained in this paper were first presented in a preliminary form at the Staff Seminar that I gave at the University of Cape Town (UCT) - Department of Private Law, on Tuesday May 8 2012. The organizers generously offered me a free choice of subject. Such an offer always poses a problem to imaginative people like myself. I finally chose as my subject the role of good faith in contract law theory and practice and then entitled the Seminar “Good Faith & Contracts - Brothers in Arms”. The aim of the talk was to briefly describe what I see behind the doctrine of good faith (and, more broadly, behind the general course of the parties’ behavior before and after the conclusion of an agreement), to then explain the need of its protection and future reasonable developments by challenging the limitations of both traditional and current legal approaches to contract law theory and practice. By adopting a comparative modus investigandi, it emerged that especially in the area of contract law a new law-finding process is emerging in the European continent and it is leading to re-conceive the meta-national legislative interventions by challenging the limits of Hobbes’s Leviathan. As asserted, we ought to not take this process for granted because although there are many forms of social organization, contract is the most pervasive and the law of contract still is the most important vehicle to support and supplement private arrangements. However, the point of departure for theorizing about private law is based on experience. Consequently, despite the growing emphasis on the convergence of national legal systems in Europe, conducting research on private law theory and practice requires that imagination and creativity be matched with prudence. Proficiency has to be aligned with what we have learned from history.

Adaptation of the international investment contract: the hardship clause

Este trabalho acadêmico explora, em linhas gerais, a questão da adaptação do contrato de investimento internacional, e o tema ‘cláusula de hardship’ em específico. Objetiva-se efetuar uma análise detalhada da cláusula de hardship, como meio de adaptação e flexibilização de contratos internacionais de investimento sob a ótica da prática jurídica e mercantil contemporânea. A discussão se centra no contraste entre a possibilidade de adaptação do contrato por circunstâncias imprevisíveis e o imperativo de previsibilidade no investimento. Nesse sentido, o estudo busca oferecer soluções práticas para o dilema existente entre a necessidade de segurança na relação econômica (cumprimento do contato) e a prevenção da possibilidade de ruína financeira para quaisquer das partes no caso de uma mudança brusca no contexto dos negócios. O trabalho está centrado em uma investigação teórica acerca dos temas de readaptação contratual; diferenças entre sistemas jurídicos de estados-nações, e suas consequências no comércio internacional; e a cláusula de hardship em si. Como forma de contribuir para uma compreensão prática na questão da adaptação do contrato de investimento internacional devido a fatores imprevistos, este trabalho analisa casos reais e tendências atuais observadas na arbitragem internacional.

The Weapons of Mass Destruction and the Global Security Strategy of the EU

The proliferation of weapons of mass destruction (WMD), nuclear, biological and chemical (NBC) is one of the main security challenges facing the international community today. However the new Global Security Strategy of 2016 raises the question of non-proliferation of WMD only as an incidental matter, not addressing directly the threat, a fundamental threat in the regional and global security. This is a clear step backwards for the European common security.

Don’t expect me to vote for you just because I like you, even if you do make me feel warm inside: a comparison of the validity of non-ipsative measures of party support

The inclusion of non-ipsative measures of party preference (in essence ratings for each of the parties of a political system) has become established practice in mass surveys conducted for election studies. They exist in different forms, known as thermometer ratings or feeling scores, likes and dislikes scores, or support propensities. Usually only one of these is included in a single survey, which makes it difficult to assess the relative merits of each. The questionnaire of the Irish National Election Study 2002 (INES2002) contained three different batteries of non-ipsative party preferences. This paper investigates some of the properties of these different indicators. We focus in particular on two phenomena. First, the relationship between non-ipsative preferences and the choices actually made on the ballot. In Ireland this relationship is more revealing than in most other countries owing to the electoral system (STV) which allows voters to cast multiple ordered votes for candidates from different parties. Second, we investigate the latent structure of each of the batteries of party preferences and the relationships between them. We conclude that the three instruments are not interchangeable, that they measure different orientations, and that one –the propensity to vote for a party– is by far preferable if the purpose of the study is the explanation of voters’ actual choice behaviour. This finding has important ramifications for the design of election study questionnaires.

Elementos para a eficácia jurídica da pluralidade contratual

A presente tese de doutorado procura mostrar que a coligação contratual, entendida como sendo a possibilidade de interferências recíprocas entre contratos, dá-se por força da conjunção do ordenamento jurídico com os fatos, não bastando a simples integração econômica entre negócios subjacentes para caracterizar a coligação do ponto de vista jurídico. A primeira das fontes da coligação contratual é a vontade das partes, através de cláusulas contratuais. As partes, por meio de acordos privados podem fazer com que efeitos decorrentes de um contrato produzam efeitos em outro. A segunda fonte é a lei. Muitas vezes o legislador quer que dois ou mais contratos se conectem de modo a que produzam alguns efeitos entre si. Nestes casos afasta-se a vontade das partes e prevalece a determinação do legislador. Por último, a coligação contratual pode ser uma aplicação do princípio da boa-fé. A confiança despertada, nas relações onde haja uma elevada integração econômica deve ser protegida.

Champ d'application de la Convention des Nations Unies sur les contrats de vente internationale de marchandises

Le champ d’application de la Convention de Vienne de 1980 sur la vente internationale de marchandises constitue une question très délicate. En effet, le caractère abstrait et supplétif de ladite Convention a donné naissance à une jurisprudence fort divergente et à une doctrine rarement en accord. Les difficultés d’application de la Convention démontrent clairement les limites de cette dernière à s’adapter aux nouveaux contrats de vente internationale. Ces difficultés sont-elles dues à une mauvaise interprétation des termes de la convention ? Serait-il juste de compléter les lacunes de la Convention de Vienne par d’autres Conventions telles que les règles d’UNIDROIT ou les principes de droit européen des contrats ? Faut-il aller «au-delà» de la Convention de Vienne ? Toutes ces questions doivent être gardées en tête pour bien analyser le champ d’application de ladite Convention.

L'interaction entre le droit civil et le droit du travail : le rôle du contrat dans l'accès aux régimes de protection des travailleurs

L’interrelation entre le droit civil et le du droit du travail présente multiples facettes. Le présent mémoire traite de l’une des manifestations de cette interaction, soit du recours à l’appareil contractuel pour donner ouverture à l’application de certaines lois de protection des travailleurs dans la sphère provinciale au Québec. L’accès aux lois du travail étant réservé aux personnes qui possèdent le statut de « travailleur » ou de « salarié » au sens de ces lois, la façon dont ces notions sont définies par le législateur est importante. Nous étudions dans notre texte l’incidence que le recours à la notion de contrat de travail peut avoir dans ce contexte. Dans la première partie du mémoire, nous étudions le rôle du droit civil dans le développement du droit du travail. Nous nous penchons sur l’existence d’un ensemble de droits et d’obligations rattaché au rapport de travail indépendamment de la volonté des parties. Ensuite, nous présentons les deux fondements possibles du rapport visé par les lois du travail, soit la thèse contractuelle et celle fondée sur la « relation du travail », ainsi que la façon dont elles sont reçues au Québec et ailleurs. Dans la troisième partie de notre texte, nous examinons les effets pratiques d’appliquer les critères du droit des contrats lorsqu’il s’agit d’établir si une personne peut bénéficier des lois du travail à partir de l’analyse de certaines décisions jurisprudentielles. Nous nous penchons de façon plus particulière sur le traitement accordé par les tribunaux aux personnes qui occupent des emplois atypiques comme les travailleurs occasionnels, saisonniers et autonomes. Nous explorons également si une approche fondée sur la réalité factuelle, les particularités du travail en cause et les objectifs des lois d’ordre public peut constituer une piste de solution à la problématique que le recours à la figure contractuelle pour déterminer l’application des lois du travail soulève.

Housing supply in Australia : the impact of the availability of development finance

Before the Global Financial Crisis many providers of finance had growth mandates and actively pursued development finance deals as a way of gaining higher returns on funds with regular capital turnover and re-investment possible. This was able to be achieved through high gearing and low presales in a strong market. As asset prices fell, loan covenants breached and memories of the 1990’s returned, banks rapidly adjusted their risk appetite via retraction of gearing and expansion of presale requirements. Early signs of loosening in bank credit policy are emerging, however parties seeking development finance are faced with a severely reduced number of institutions from which to source funding. The few institutions that are lending are filtering out only the best credit risks by way of constrictive credit conditions including: low loan to value ratios, the corresponding requirement to contribute high levels of equity, lack of support in non-prime locations and the requirement for only borrowers with well established track records. In this risk averse and capital constrained environment, the ability of developers to proceed with real estate developments is still being constrained by their inability to obtain project finance. This paper will examine the pre and post GFC development finance environment. It will identify the key lending criteria relevant to real estate development finance and will detail the related changes to credit policies over this period. The associated impact to real estate development projects will be presented, highlighting the significant constraint to supply that the inability to obtain finance poses.

An evaluation of the sustainability of agreements reached through mediations conducted by the dispute resolution centres of the Department of Justice and Attorney General, Queensland between 1999 to 2003

In 1990 the Dispute Resolution Centres Act, 1990 (Qld) (the Act) was passed by the Queensland Parliament. In the second reading speech for the Dispute Resolution Centres Bill on May 1990 the Hon Dean Wells stated that the proposed legislation would make mediation services available “in a non-coercive, voluntary forum where, with the help of trained mediators, the disputants will be assisted towards their own solutions to their disputes, thereby ensuring that the result is acceptable to the parties” (Hansard, 1990, 1718). It was recognised at that time that a method for resolving disputes was necessary for which “the conventional court system is not always equipped to provide lasting resolution” (Hansard, 1990, 1717). In particular, the lasting resolution of “disputes between people in continuing relationships” was seen as made possible through the new legislation; for example, “domestic disputes, disputes between employees, and neighbourhood disputes relating to such issues as overhanging tree branches, dividing fences, barking dogs, smoke, noise and other nuisances are occurring continually in the community” (Hansard, 1990, 1717). The key features of the proposed form of mediation in the Act were articulated as follows: “attendance of both parties at mediation sessions is voluntary; a party may withdraw at any time; mediation sessions will be conducted with as little formality and technicality as possible; the rules of evidence will not apply; any agreement reached is not enforceable in any court; although it could be made so if the parties chose to proceed that way; and the provisions of the Act do not affect any rights or remedies that a party to a dispute has apart from the Act” (Hansard, 1990, 1718). Since the introduction of the Act, the Alternative Dispute Resolution Branch of the Queensland Department of Justice and Attorney General has offered mediation services through, first the Community Justice Program (CJP), and then the Dispute Resolution Centres (DRCs) for a range of family, neighbourhood, workplace and community disputes. These services have mirrored those available through similar government agencies in other states such as the Community Justice Centres of NSW and the Victorian Dispute Resolution Centres. Since 1990, mediation has become one of the fastest growing forms of alternative dispute resolution (ADR). Sourdin has commented that "In addition to the growth in court-based and community-based dispute resolution schemes, ADR has been institutionalised and has grown within Australia and overseas” (2005, 14). In Australia, in particular, the development of ADR service provision “has been assisted by the creation and growth of professional organisations such as the Leading Edge Alternative Dispute Resolvers (LEADR), the Australian Commercial Dispute Centres (ACDC), Australian Disputes Resolution Association (ADRA), Conflict Resolution Network, and the Institute of Arbitrators and Mediators Australia (IAMA)” (Sourdin, 2005, 14). The increased emphasis on the use of ADR within education contexts (particularly secondary and tertiary contexts) has “also led to an increasing acceptance and understanding of (ADR) processes” (Sourdin, 2005, 14). Proponents of the mediation process, in particular, argue that much of its success derives from the inherent flexibility and creativity of the agreements reached through the mediation process and that it is a relatively low cost option in many cases (Menkel-Meadow, 1997, 417). It is also accepted that one of the main reasons for the success of mediation can be attributed to the high level of participation by the parties involved and thus creating a sense of ownership of, and commitment to, the terms of the agreement (Boulle, 2005, 65). These characteristics are associated with some of the core values of mediation, particularly as practised in community-based models as found at the DRCs. These core values include voluntary participation, party self-determination and party empowerment (Boulle, 2005, 65). For this reason mediation is argued as being an effective approach to resolving disputes, that creates a lasting resolution of the issues. Evaluation of the mediation process, particularly in the context of the growth of ADR, has been an important aspect of the development of the process (Sourdin, 2008). Writing in 2005 for example, Boulle, states that “although there is a constant refrain for more research into mediation practice, there has been a not insignificant amount of mediation measurement, both in Australia and overseas” (Boulle, 2005, 575). The positive claims of mediation have been supported to a significant degree by evaluations of the efficiency and effectiveness of the process. A common indicator of the effectiveness of mediation is the settlement rate achieved. High settlement rates for mediated disputes have been found for Australia (Altobelli, 2003) and internationally (Alexander, 2003). Boulle notes that mediation agreement rates claimed by service providers range from 55% to 92% (Boulle, 2005, 590). The annual reports for the Alternative Dispute Resolution Branch of the Queensland Department of Justice and Attorney-General considered prior to the commencement of this study indicated generally achievement of an approximate settlement figure of 86% by the Queensland Dispute Resolution Centres. More recently, the 2008-2009 annual report states that of the 2291 civil dispute mediated in 2007-2008, 86% reached an agreement. Further, of the 2693 civil disputes mediated in 2008-2009, 73% reached an agreement. These results are noted in the report as indicating “the effectiveness of mediation in resolving disputes” and as reflecting “the high level of agreement achieved for voluntary mediations” (Annual Report, 2008-2009, online). Whilst the settlement rates for the DRCs are strong, parties are rarely contacted for long term follow-up to assess whether agreements reached during mediation lasted to the satisfaction of each party. It has certainly been the case that the Dispute Resolution Centres of Queensland have not been resourced to conduct long-term follow-up assessments of mediation agreements. As Wade notes, "it is very difficult to compare "success" rates” and whilst “politicians want the comparison studies (they) usually do not want the delay and expense of accurate studies" (1998, 114). To date, therefore, it is fair to say that the efficiency of the mediation process has been evaluated but not necessarily its effectiveness. Rather, the practice at the Queensland DRCs has been to evaluate the quality of mediation service provision and of the practice of the mediation process. This has occurred, for example, through follow-up surveys of parties' satisfaction rates with the mediation service. In most other respects it is fair to say that the Centres have relied on the high settlement rates of the mediation process as a sign of the effectiveness of mediation (Annual Reports 1991 - 2010). Research of the mediation literature conducted for the purpose of this thesis has also indicated that there is little evaluative literature that provides an in-depth analysis and assessment of the longevity of mediated agreements. Instead evaluative studies of mediation tend to assess how mediation is conducted, or compare mediation with other conflict resolution options, or assess the agreement rate of mediations, including parties' levels of satisfaction with the service provision of the dispute resolution service provider (Boulle, 2005, Chapter 16).
