The EMU sovereign-debt crisis: Fundamentals, expectations and contagion

We offer a detailed empirical investigation of the European sovereign debt crisis based on the theoretical model by Arghyrou and Tsoukalas (2010). We find evidence of a marked shift in market pricing behaviour from a ‘convergence-trade’ model before August 2007 to one driven by macro-fundamentals and international risk thereafter. The majority of EMU countries have experienced contagion from Greece. There is no evidence of significant speculation effects originating from CDS markets. Finally, the escalation of the Greek debt crisis since November 2009 is confirmed as the result of an unfavourable shift in countryspecific market expectations. Our findings highlight the necessity of structural, competitiveness-inducing reforms in periphery EMU countries and institutional reforms at the EMU level enhancing intra-EMU economic monitoring and policy co-ordination.

International Society of Urological Pathology (ISUP) Consensus Conference on Handling and Staging of Radical Prostatectomy Specimens. Working group 1: specimen handling.

The 2009 International Society of Urological Pathology Consensus Conference in Boston made recommendations regarding the standardization of pathology reporting of radical prostatectomy specimens. Issues relating to the handling and processing of radical prostatectomy specimens were coordinated by working group 1. Most uropathologists followed similar procedures for fixation of radical prostatectomy specimens, with 51% of respondents transporting tissue in formalin. There was also consensus that the prostate weight without the seminal vesicles should be recorded. There was consensus that the surface of the prostate should be painted. It was agreed that both the prostate apex and base should be examined by the cone method with sagittal sectioning of the tissue sample. There was consensus that the gland should be fully fixed before sectioning. Both partial and complete embedding of prostates was considered to be acceptable as long as the method of partial embedding is stated. No consensus was determined regarding the necessity of weighing and measuring the length of the seminal vesicles, the preparation of whole mounts rather than standardized blocks and the methodology for sampling of fresh tissue for research purposes, and it was agreed that these should be left to the discretion of the working pathologist.

Attribution d'intentions hostiles et intentions comportementales agressives dans un contexte intergroupes

We conducted two experiments to demonstrate the relevance of group membership (in-group vs. out-group) in the processing of conflictual social interactions as described by Dodge (1980; Dodge, Pettit, Mcclaskey, & Brown, 1986). In the first study, we highlighted the impact of group membership on the attribution of hostile intents and on reactions to a provocation. In the second study we found that the impact of group membership on aggressive reaction intents is moderated by the status of people in the interaction, and that this effect is partially mediated by attribution of hostile intents. We conclude by stressing the necessity to integrate intergroup dynamics in the social information processing model elaborated by Dodge.

Women at home, at school and in the factory. The particular discourse of domesticity done by the Spanish Escuela Economista (1861-1909)

The texts by the Spanish Economist School (second half of the 19th century) contain an assessment of the role of women in the economy and society that is transgressor in front of the prevailing discourse that defended a unique and exclusive role for all women: being at home and a mother. Most members of that economic trend defended female work in the factories, basing themselves on wage arguments and even asked for a professional training for those who in many cases could not even write and read for the fact of being a woman. The texts of those economists give new ideas about the economic and social role of women in a Spain dominated by a discourse that denied the necessity of female work for the working families.

Estudio para la implantación de un ERP en una empresa de fabricación de depósitos

Aquest projecte intenta proporcionar les bases per la selecció i implantació d’un ERP a una empresa mitjana. S’analitzen des dels primers passos a realitzar per l’empresa que adquirirà l’ERP fins els que realitza el proveïdor per garantir l’èxit de la implantació. Primerament, i des del punt de vista del client, es realitza una anàlisi interna per detectar la necessitat d’un canvi de sistema i es detalla una metodologia a seguir per a l’elecció de l’ERP i del proveïdor d’aquest, minimitzant el risc d’error. Des del punt de vista del proveïdor es seguirà una metodologia d’implantació pas per pas, ja què un canvi de sistema és una tasca molt complexa. He intentat aportar la meva experiència al realitzar aquest projecte ja que he tingut l'oportunitat de viure una implantació des de les dues òptiques i he aprofitat per indagar en les tasques que s’hi realitzen.

Desconnexió de la xarxa

Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit cientí­fic del Jovent l'any 2009. Aquest treball es planteja com un repte la necessitat de connexió a una xarxa de subministrament elèctric i d'aigua. L'objectiu del treball ha estat comprovar si, tan tècnicament com econòmica, es pot aconseguir l'autosuficiència d'una casa de muntanya del Vallès Oriental tot aprofitant els recursos que ens ofereix el medi, però sense haver de renunciar al nivell de vida al qual ens hem acostumat durant els darrers anys. Després d'una recollida de dades i valoració del consum energètic mínim que volem imposar, hem dissenyat una instal·lació capaç d'aprofitar les energies renovables de l'entorn i de satisfer les nostres necessitats. La instal·lació inclou plaques fotovoltaiques, col·lectors solars, cisternes per a la recollida d'aigua, bombes, etc. Finalment, s'inclou un pressupost d'aquesta instal·lació, que indica que els diners que caldria invertir són massa. Es demostra, doncs, que l'autosuficiència d'aquesta casa és tècnicament viable, però econòmicament inviable (o gens rendible).

Early-onset Crohn's disease is a risk factor for smaller final height.

OBJECTIVES: Growth retardation is a frequent complication of paediatric inflammatory bowel disease (IBD). Only a few studies report the final height of these patients, with controversial results. We compared adult height of patients with paediatric IBD with that of patients with adult-onset disease. METHODS: Height data of 675 women 19-44 years of age and 454 men 23-44 years of age obtained at inclusion in the Swiss IBD cohort study registry were grouped according to the age at diagnosis: (a) prepubertal (men≤13, women≤11 years), (b) pubertal (men 13-22, women 11-18 years) and (c) adult (men>22, women>18 years of age), and compared with each other and with healthy controls. RESULTS: Male patients with prepubertal onset of Crohn's disease (CD) had significantly lower final height (mean 172±6 cm, range 161-182) compared with men with pubertal (179±6 cm, 161-192) or adult (178±7 cm, 162-200) age at onset and the general population (178±7 cm, 142-204). Height z-scores standardized against heights of the normal population were significantly lower in all patients with a prepubertal diagnosis of CD (-0.8±0.9) compared with the other patient groups (-0.1±0.8, P<0.001). Prepubertal onset of CD emerged as a risk factor for reduced final height in patients with prepubertal CD. No difference for final height was found between patients with ulcerative or unclassified IBD diagnosed at prepubertal, pubertal or adult age. CONCLUSION: Prepubertal onset of CD is a risk for lower final height, independent of the initial disease location and the necessity for surgical interventions.

La relation ambiguë des protestantismes à la sociologie

(Résumé de l'ouvrage) What are the relations between sociology and the different religions - Christianity with its various branches, Judaism, Islam, Oriental religions, sects and New Religious Movements ? That is the question which this work, - conceived on the occasion of the XXVth Conference of the International Society for the Sociology of Religion/Société Internationale de Sociologie des Religions (SISR) - wishes to clarify. The book retraces the varied and troubled history of these relations and also reveals how in opening up its research to other religions besides the Christan, sociology is forced to redefine the very object of its field of study. What is the religious? This question, which until recently was considered impertinent, informs this book throughout. If confronts the necessity of rethinking theories and methodological appoaches which, constructed in the context of 19th and early 20th century Western Europe, prove to be rather inadequate for encompassing contemporary religious phenomena and religious manifestations in other contexts. To these new theoretical and methodological demands is added, for the sociologist, a deontological imperative, which takes on all the more importance today as the religious provokes passionate social debate.

Overuse and underuse of colonoscopy in a European primary care setting.

BACKGROUND: Efforts to decrease overuse of health care may result in underuse. Overuse and underuse of colonoscopy have never been simultaneously evaluated in the same patient population. METHODS: In this prospective observational study, the appropriateness and necessity of referral for colonoscopy were evaluated by using explicit criteria developed by a standardized expert panel method. Inappropriate referrals constituted overuse. Patients with necessary colonoscopy indications who were not referred constituted underuse. Consecutive ambulatory patients with lower gastrointestinal (GI) symptoms from 22 general practices in Switzerland, a country with ready access to colonoscopy, were enrolled during a 4-week period. Follow-up data were obtained at 3 months for patients who did not undergo a necessary colonoscopy. RESULTS: Eight thousand seven hundred sixty patient visits were screened for inclusion; 651 patients (7.4%) had lower GI symptoms (mean age 56.4 years, 68% women). Of these, 78 (12%) were referred for colonoscopy. Indications for colonoscopy in 11 patients (14% of colonoscopy referrals or 1.7% of all patients with lower GI symptoms) were judged inappropriate. Among 573 patients not referred for the procedure, underuse ranged between 11% and 28% of all patients with lower GI symptoms, depending on the criteria used. CONCLUSIONS: Applying criteria from an expert panel of nationally recognized experts indicates that underuse of referral for colonoscopy exceeds overuse in primary care in Switzerland. To improve quality of care, both overuse and underuse of important procedures must be addressed.

Towards the validation of "in silico" models and physicochemical filters to identify and characterize new chemical entities

Summary: Lipophilicity plays an important role in the determination and the comprehension of the pharmacokinetic behavior of drugs. It is usually expressed by the partition coefficient (log P) in the n-octanol/water system. The use of an additional solvent system (1,2-dichlorethane/water) is necessary to obtain complementary information, as the log Poct values alone are not sufficient to explain ail biological properties. The aim of this thesis is to develop tools allowing to predict lipophilicity of new drugs and to analyze the information yielded by those log P values. Part I presents the development of theoretical models used to predict lipophilicity. Chapter 2 shows the necessity to extend the existing solvatochromic analyses in order to predict correctly the lipophilicity of new and complex neutral compounds. In Chapter 3, solvatochromic analyses are used to develop a model for the prediction of the lipophilicity of ions. A global model was obtained allowing to estimate the lipophilicity of neutral, anionic and cationic solutes. Part II presents the detailed study of two physicochemical filters. Chapter 4 shows that the Discovery RP Amide C16 stationary phase allows to estimate lipophilicity of the neutral form of basic and acidic solutes, except of lipophilic acidic solutes. Those solutes present additional interactions with this particular stationary phase. In Chapter 5, 4 different IANI stationary phases are investigated. For neutral solutes, linear data are obtained whatever the IANI column used. For the ionized solutes, their retention is due to a balance of electrostatic and hydrophobie interactions. Thus no discrimination is observed between different series of solutes bearing the same charge, from one column to an other. Part III presents two examples illustrating the information obtained thanks to Structure-Properties Relationships (SPR). Comparing graphically lipophilicity values obtained in two different solvent systems allows to reveal the presence of intramolecular effects .such as internai H-bond (Chapter 6). SPR is used to study the partitioning of ionizable groups encountered in Medicinal Chemistry (Chapter7). Résumé La lipophilie joue un .rôle important dans la détermination et la compréhension du comportement pharmacocinétique des médicaments. Elle est généralement exprimée par le coefficient de partage (log P) d'un composé dans le système de solvants n-octanol/eau. L'utilisation d'un deuxième système de solvants (1,2-dichloroéthane/eau) s'est avérée nécessaire afin d'obtenir des informations complémentaires, les valeurs de log Poct seules n'étant pas suffisantes pour expliquer toutes les propriétés biologiques. Le but de cette thèse est de développer des outils permettant de prédire la lipophilie de nouveaux candidats médicaments et d'analyser l'information fournie par les valeurs de log P. La Partie I présente le développement de modèles théoriques utilisés pour prédire la lipophilie. Le chapitre 2 montre la nécessité de mettre à jour les analyses solvatochromiques existantes mais inadaptées à la prédiction de la lipophilie de nouveaux composés neutres. Dans le chapitre 3, la même méthodologie des analyses solvatochromiques est utilisée pour développer un modèle permettant de prédire la lipophilie des ions. Le modèle global obtenu permet la prédiction de la lipophilie de composés neutres, anioniques et cationiques. La Partie II présente l'étude approfondie de deux filtres physicochimiques. Le Chapitre 4 montre que la phase stationnaire Discovery RP Amide C16 permet la détermination de la lipophilie de la forme neutre de composés basiques et acides, à l'exception des acides très lipophiles. Ces derniers présentent des interactions supplémentaires avec cette phase stationnaire. Dans le Chapitre 5, 4 phases stationnaires IAM sont étudiées. Pour les composés neutres étudiés, des valeurs de rétention linéaires sont obtenues, quelque que soit la colonne IAM utilisée. Pour les composés ionisables, leur rétention est due à une balance entre des interactions électrostatiques et hydrophobes. Donc aucune discrimination n'est observée entre les différentes séries de composés portant la même charge d'une colonne à l'autre. La Partie III présente deux exemples illustrant les informations obtenues par l'utilisation des relations structures-propriétés. Comparer graphiquement la lipophilie mesurée dans deux différents systèmes de solvants permet de mettre en évidence la présence d'effets intramoléculaires tels que les liaisons hydrogène intramoléculaires (Chapitre 6). Cette approche des relations structures-propriétés est aussi appliquée à l'étude du partage de fonctions ionisables rencontrées en Chimie Thérapeutique (Chapitre 7) Résumé large public Pour exercer son effet thérapeutique, un médicament doit atteindre son site d'action en quantité suffisante. La quantité effective de médicament atteignant le site d'action dépend du nombre d'interactions entre le médicament et de nombreux constituants de l'organisme comme, par exemple, les enzymes du métabolisme ou les membranes biologiques. Le passage du médicament à travers ces membranes, appelé perméation, est un paramètre important à optimiser pour développer des médicaments plus puissants. La lipophilie joue un rôle clé dans la compréhension de la perméation passive des médicaments. La lipophilie est généralement exprimée par le coefficient de partage (log P) dans le système de solvants (non miscibles) n-octanol/eau. Les valeurs de log Poct seules se sont avérées insuffisantes pour expliquer la perméation à travers toutes les différentes membranes biologiques du corps humain. L'utilisation d'un système de solvants additionnel (le système 1,2-dichloroéthane/eau) a permis d'obtenir les informations complémentaires indispensables à une bonne compréhension du processus de perméation. Un grand nombre d'outils expérimentaux et théoriques sont à disposition pour étudier la lipophilie. Ce travail de thèse se focalise principalement sur le développement ou l'amélioration de certains de ces outils pour permettre leur application à un champ plus large de composés. Voici une brève description de deux de ces outils: 1)La factorisation de la lipophilie en fonction de certaines propriétés structurelles (telle que le volume) propres aux composés permet de développer des modèles théoriques utilisables pour la prédiction de la lipophilie de nouveaux composés ou médicaments. Cette approche est appliquée à l'analyse de la lipophilie de composés neutres ainsi qu'à la lipophilie de composés chargés. 2)La chromatographie liquide à haute pression sur phase inverse (RP-HPLC) est une méthode couramment utilisée pour la détermination expérimentale des valeurs de log Poct.

Schistosomiasis mansoni in the region of the Triângulo Mineiro, State of Minas Gerais, Brazil

In order to reevaluate the possible presence of schistosomiasis mansoni in the Triângulo Mineiro, one of the areas of the State of Minas Gerais where this parasite is not commonly found, malacological survey and fecal examinations were undertaken in the region between October 1990 and June 1992. A sample of 7,032 1st grade school children from 29 counties had their feces examined using the Kato-Katz method. Amongst the children examined, two from Planura and one from each countie of Capinópolis, Conceição das Alagoas, Uberaba, Uberlândia, Prata and Gurinhatã were positive for Schistosoma mansoni. None of the children were identified as being autoctonous cases. In the malacological survey, 5,406 planorbid snails were examined. The specimens were identified morphologically and examined for S. mansoni by squashing between glass plates. The species were identified as Biomphalaria tenagophila in three counties, as B. straminea in ten and B. intermedia in 16. No snails were found in eight other counties studies. The snails were found to be negative for S. mansoni. The presence of intermediate hosts for S. mansoni, associated with parasitized individuals emphasizes the necessity of epidemiological surveillance for schistosomiasis in the region of Triângulo in the State of Minas Gerais.

Banning Obsolete Weapons or Reshaping Perceptions of Military Utility: Discursive Dynamics in Weapons Prohibitions

The paper focuses on the argumentative process through which new international norms prohibiting the use of weapons causing severe civilian harm emerge. It examines the debate surrounding the use and usefulness of landmines and cluster munitions and traces the process through which NGOs change conceptions of military utility and effectiveness of certain weapons by highlighting their humanitarian problems and questioning their military value. By challenging military thinking on these issues, NGOs redefine the terms of the debate – from a commonplace practice, the use of such weapons becomes controversial and military decisions need to be justified. The argument-counterargument dynamic shifts the burden of proof of the necessity and safety of the weapons to the users. The process witnesses the ability of NGOs to influence debates on military issues despite their disadvantaged position in hard security issue areas. It also challenges realist assumptions that only weapons that are obsolete or low-cost force equalizers for weak actors can be banned. To the contrary, the paper shows that in the case of landmines and cluster munitions, defining the military (in)effectiveness of the weapons is part and parcel of the struggle for their prohibition.
