It is argued that several papers where SU(3) Clebsch-Gordan coefficients were calculated in order to describe properties of hadronic systems are, up to a phase convention, particular cases of analytic formulae derived by Hecht in 1965 in the context of nuclear physics. This is valid for irreducible representations with multiplicity one in the corresponding Clebsch-Gordan series. For multiplicity two, Hecht has proposed an alternative which can provide correct $1/N_c$ sub-leading orders in large $N_c$ studies. [less ▲]

In the dual context of increased Central and Eastern European migration and of the global financial and economic crisis, several Northern European Member States have implemented (or debated) reforms of their welfare regimes to restrict access to migrants coming from other EU Member States. As the debates on the so-called “welfare tourism” are intensifying in different parts of the EU, we can observe a growing trend among Member States to use welfare policies as instruments to limit the mobility of certain EU migrants. This stance is best illustrated with Prime Minister Cameron’s demand for four-year ban on EU migrants claiming in-work benefits. In Belgium, too, EU citizens have been particularly affected by this adverse context as the Migration Office (Office des Etrangers) has intensified controls against EU residents receiving welfare benefits. With this policy, authorities have been using a restrictive interpretation of the European Directive 2004/38 that allows Member States to remove residence permits from EU citizens who represent an “unreasonable burden on state finances”. As a consequence, the number of EU citizens expelled from Belgium on a yearly basis has jumped from 343 to 2,042 between 2010 and 2014. In this paper, we propose to focus on those EU citizens who see their freedom of circulation in the EU restricted after claiming social protection in their country of residence. Relying on fieldwork conducted with Italian and Romanian migrants who experienced the removal of their residence permit, we discuss the different resilience strategies of those EU citizens faced with the legal obligation to leave: such strategies include returning to the homeland, refusing to leave, mobilizing the support of migrant organizations, introducing individual appeals, and seeking to regularize their administrative status. In particular, we shall focus on the experience of EU migrants who have decided to stay in Belgium and experience the status of an undocumented EU migrant. This peculiarity of this status is visible in three respects: 1) expulsion is not enforced by local authorities, 2) migrants continue to be able to circulate between their homeland and the country where they no longer have a residence permit, and 3) they have a possibility to regularize their status if they can demonstrate to municipal authorities that they no longer represent “a burden” on Belgium’s public finances. Overall, confronting our data to the rich literature on undocumented third country nationals, we discuss the limits of EU citizenship as experienced by those who are denied the right to free movement. This paper relies primarily on multi-sited ethnographic fieldwork (in progress) conducted with Italian and Romanian migrants in Brussels and with individuals of the same nationality who decided to leave Belgium and return to their home country after the removal of their residence permit. Additional fieldwork includes semi-directed interviews with civil society organizations, trade unions, and consular authorities. The data collection process started in May 2014 and is expected to be finished in May 2016. [less ▲]

Cet ouvrage concis s'intéresse au thymus, un organe dont la fonction a échappé si longtemps au monde de la science que d'aucuns le considèrent encore aujourd'hui comme un vestige de l'évolution. Vous le connaissez néanmoins très bien car vous avez certainement consommé de très savoureux 'ris de veau' qui sont la dénomination culinaire du thymus de cet animal. Ce n'est qu'au cours des 60 dernières années environ que cet organe a livré un à un ses secrets les plus intimes jusqu'à occuper la place essentielle de 'petit cerveau' de notre système de défenses immunitaires. Cet essai concerne donc aussi l’immunologie, la science qui étudie les mécanismes de notre système de défenses, contre les agressions infectieuses surtout, en un mot l’immunité. Dès la fondation de cette nouvelle science à la fin du XIXe siècle, les immunologistes ont été confrontés à cet important paradoxe: comment notre système immunitaire, capable de réagir contre une multitude d’agents étrangers (ce qui est désigné comme le ‘non-soi’), est-il heureusement incapable en conditions normales d’agresser l’organisme qui l’héberge (le ‘soi’) ? Cette impossibilité du système immunitaire de réagir contre le ‘soi’ s’appelle la ‘tolérance immunitaire’ et elle est devenue aujourd’hui la pierre angulaire du fonctionnement normal de ce système. La rupture de cette tolérance est à l’origine des maladies dites ‘auto-immunes’. Il en existe environ 70 dont les plus connues sont le diabète juvénile insulino-dépendant (diabète de type 1) qui frappe les enfants et les jeunes adolescents, la plupart des affections de la glande thyroïde, la sclérose en plaques, le psoriasis et la polyarthrite rhumatoïde. J’ai souhaité inviter le lecteur à pénétrer dans un monde qui était encore presque inconnu il y a moins de soixante ans, celui du thymus qui peut être qualifié aujourd’hui sinon de ‘cerveau’, au moins de programmeur central de la tolérance immunitaire. Les travaux menés par mon groupe à l’Université de Liège ont établi que le thymus constitue un carrefour crucial entre les trois grands systèmes de communication intercellulaire des espèces vivantes, les systèmes nerveux, endocrine et immunitaire. Ils ont démontré que le thymus joue un rôle unique dans la programmation de la tolérance immunitaire vis-à-vis des systèmes nerveux et endocrine. Ces études ont aussi établi qu’un dysfonctionnement du thymus joue un rôle moteur dans le développement des maladies auto-immunes spécifiques des glandes endocrines. En un mot, c’est d’abord le thymus qui est malade et non les organes touchés par le processus auto-immun pathogène qui résulte de cette pathologie du thymus. Mon plus vif espoir aujourd’hui est que la découverte de ce nouveau concept se traduise un jour par l’invention d’un nouveau type de vaccination contre le diabète des enfants et des adolescents. Quelles sont les raisons qui ont motivé ma candidature au Prix littéraire Prince Alexandre de Belgique 2014. 1° La première était de témoigner ma reconnaissance à l’égard de la Fondation cardiologique Princesse Lilian qui a joué un rôle déterminant dans l’orientation de ma carrière de médecin-chercheur. En effet, cette Fondation a organisé en 1984 à Bruxelles un symposium international consacré au contrôle exercé par le système nerveux sur le système immunitaire. Mon promoteur, le regretté Pr Paul Franchimont, avait assisté à ce symposium et me conseilla vivement d’essayer de développer des activités de recherches dans ce tout nouveau domaine. C’est dans ce même esprit de reconnaissance à la Fondation Princesse Lilian que j’ai proposé que la chaire internationale du même nom soit confiée en 2015 à mon confrère allemand, lui aussi spécialiste du thymus, le Pr Bruno Kyewski de l’Institut allemand de la recherche contre le cancer à Heidelberg en Allemagne. Cette proposition a été acceptée et la leçon inaugurale de cette chaire a eu lieu le 16 mars 2015 en la Grande Salle Académique de l’Université de Liège. 2° Mon goût pour la littérature, qu’elle soit romancière, historique, scientifique ou philosophique, constitue incontestablement la deuxième raison de ma candidature au Prix Prince Alexandre. Combien de fois n’ai-je lu une œuvre littéraire en m’interrogeant si je serais capable moi-même d’écrire un jour un livre ? C’est aussi en me plongeant dans la littérature que j’ai vécu les plus beaux voyages initiatiques de la pensée. 3° Une autre raison essentielle qui m’a poussé à rédiger mes « Voyage(s) à travers le thymus » est la suivante. L’équipe de recherche que j’anime au Centre d’Immunologie du GIGA de Liège a contribué à mettre au jour un phénomène essentiel de la vie qui est apparu avec le premier thymus il y a environ 450 millions d’années chez les poissons cartilagineux comme la raie ou le requin. Cette ‘découverte’ d’un secret inouï de la vie suscite alors en vous une sensation d’émerveillement du même ordre que l’émotion qui vous étreint quand vous écoutez l’Oratorio de Noël ou la Passion selon Saint-Mathieu de Jean-Sébastien Bach, quand vous regardez un tableau de Piero de la Francesca, ou quand vous contemplez une merveille de la Nature comme le Grand Canyon du Colorado ou le lever du soleil sur Massif du Hoggar depuis l’ermitage du Père de Foucault à l’Assekrem. Vous pouvez très bien vivre seul un pareil émerveillement mais le premier désir que vous ressentez au fond de vous-même est de le partager avec vos proches. Ce désir irrésistible a joué lui aussi un rôle déterminant dans ma décision de consacrer la majeure partie de mes soirées de l'été 2014 à écrire ce texte et, surtout, à le rédiger de manière compréhensible pour toutes et tous. Et c’est là que réside la plus grande difficulté car, comme le disait Albert Einstein, « Si vous ne pouvez expliquer un concept à un enfant de six ans, c'est que vous ne le comprenez pas complètement ». 4° Enfin, les trente-cinq années de ma vie de médecin engagé dans la recherche ont exercé un impact considérable sur ma propre conception de la vie et de ses innombrables mystères. Mon essai se clôture par un témoignage personnel décrivant comment ces différents voyages ont nourri ma réflexion à propos des rapports entre la science et la foi. J’ai tenté d’expliquer qu’il était encore possible aujourd’hui de rester chrétien en devenant un scientifique quelque peu écouté, comment mes vies professionnelle et spirituelle pouvaient se nourrir l’une de l’autre tout en respectant leur indépendance.

In this paper, we evaluate the in-control performance of np-control charts with estimated parameters. We then apply the bootstrap method to adjust the control charts’ limits to guarantee the desired in-control average run length (ARL0) value in monitoring stage. The adjusted limits ensure that ARL0 would take a value greater than the desired value (say, B) with a certain specified probability, that is Pr⁡(ARL_0>B)=1-ρ. We finally provide users with tables which with practitioners do not need to do bootstrapping Phase I data set to obtain the control limit thresholds. [less ▲]

Continuous monitoring of Delivery Time variables by means of control charts in a delivery chain is a very recent application of Statistical Process Control (SPC) to the service sector. The aim of the proposed method is to provide supply chain decision makers with an easy to be managed tool monitoring the current functioning state of the delivery chain. The implementation of SPC control charts makes it possible to limit over-corrections to false alarm conditions and to maintain at an acceptable level the safety stock, with a consequent reduction of the overall management costs of the delivery chain. An illustrative example shows the proposed control chart implementation in a real delivery chain. [less ▲]

n the first volume of his Mythologiques, entitled The Raw and the Cooked, Claude Lévi-Strauss argued that the preparation of food is a form of language that reveals a society's structure. For Lévi-Strauss, the so-called culinary triangle of the raw, the rotten and the cooked represents a semantic field within which the various forms of transformation of food from nature into culture play a key role. Since Lévi-Strauss, following extensive changes to food production, preparation and consumption, the notion of cooking has become ever more diversified, and became increasingly contentious. Yet, the multiple ways of combining and processing ingredients still give social and cultural meanings to food and trigger the creation of sociabilities and belongings through its own destruction (Gell 1986). This panel aims to explore Levi-Strauss' legacy and evaluate its usefulness in today's context from different angles, ranging from domestic food preparation to industrial production and global circulations of food. To what extent can this concept still provide an interpretative framework of topical food issues? Which contemporary myths does it shed light on? How could it be deployed to read the history of food and link it to contemporary questions? This panel welcomes papers on the history of food preparation, contemporary food preparation, including debates in professional and multimedia circles, various forms of food production and the possible transformation of food within globalised food markets. Although mobilizing a classic anthropological theory, this panel aims to be interdisciplinary and to present a diverse range of analytical perspectives. [less ▲]

Recently, companies are forming strong relationships with their strategic suppliers and customers in order to maximize their profit in the global market. Such a partnership or strategic alliance is based on the mutual needs of both parties. A partnership network is formed by different strategic firms (e.g., suppliers, manufacturers, distributors, retailers) who intend to establish strong relationships together but without losing their ownership, power and control on the firm. For example, if supplier X has a strong relationship with customer Y and Y has a strong relationship with supplier Z, then X, Y and Z can form a partnership network with three nodes (X, Y and Z) and two edges (X ->Y and Z->Y). In this paper, we develop a statistical methods to study the normal behaviour of partnership networks. We furthermore develop a methodology that will help diagnose the nature of identified unusual network behavior. [less ▲]

The in-control performance of the Shewhart X ̅ and S2 control charts with estimated in-control parameters has been evaluated by a number of authors. Results indicate an unrealistically large amount of Phase I data is needed to have the desired in-control average run length (ARL) value in Phase II. To overcome this problem, it has been recommended that the control limits be adjusted based on a bootstrap method to guarantee that the in-control ARL is at least a specified value with a certain specified probability. In our paper we present simple formulas for the required control limits so that practitioners do not have to use the bootstrap method. An assumption of normality is required. The advantage of our proposed method is in its simplicity; there is no bootstrapping and the control chart constants do not depend on the Phase I sample data. [less ▲]
