From explicit prohibition to ambiguity in prohibiting
El trabajo fue presentado en la secciĂłn monogrĂĄfica sobre lenguaje tabĂș en el mencionado congreso.This contribution will deal with two topics closely related and intermingled. I firstly will try to show how one of the salient features of euphemisms is their ambiguity and/or vagueness (Grondelaers and Geeraerts, 1998) to the extent that even sentences in which lexicalised euphemisms are used can become dysphemistic if they are not ambiguous. This means that ambiguous and/or vague sentences play a fundamental, cognitive role (Tuggy, 2006). This is the case of a well-known excerpt from Somerset Maugham in which, in spite of the fact that all the nouns used are euphemisms, the excerpt itself can be considered dysphemistic. Conversely, I will show two instances from two songs in which female pudenda are euphemistically and ambiguously alluded to. Secondly, I will try to apply my previous reflections to politically correct language. In order to do so I will take as a starting point the fact that political correctness spread across the western countries in the same decade (1960-1970) in which the motto âIl est interdit dâinterdireâ got also trendy (Hughes, 2006 and 2010). As a result of the fact that the noun âprohibitionâ (and its cognates, derivatives and synonyms) became âprohibitedâ as a politically incorrect word, prohibition itself has to be phrased in ambiguous sentences. For instance, instead of the (currently) politically incorrect notice âNo Smokingâ or âSmoking is prohibitedâ, we frequently find the politically correct one âThank you for not smokingâ, where the sentence meaning is pretty different from what the author of the notice tries to mean; since the sentence meaning is that someone thanks you for not smoking, while what the author of the notice intends to mean that smoking is prohibited.Universidad de MĂĄlaga.

Influence of the cosmological expansion on small systems
The effect of the large-scale cosmological expansion on small systems is
studied in the light of modern cosmological models of large-scale structure. We
identify certain assumptions of earlier works which render them unrealistic
regarding these cosmological models. The question is reanalyzed by dropping
these assumptions to conclude that a given small system can experience either
an expansion or a contraction of cosmological origin.Comment: 7 pages. Accepted for publication in Europhysics Letter
Dynamic transition in Landau-Zener-St\"uckelberg interferometry of dissipative systems: the case of the flux qubit
We study Landau-Zener-Stuckelberg (LZS) interferometry in multilevel systems
coupled to an Ohmic quantum bath. We consider the case of superconducting flux
qubits driven by a dc+ac magnetic fields, but our results can apply to other
similar systems. We find a dynamic transition manifested by a symmetry change
in the structure of the LZS interference pattern, plotted as a function of ac
amplitude and dc detuning. The dynamic transition is from a LZS pattern with
nearly symmetric multiphoton resonances to antisymmetric multiphoton resonances
at long times (above the relaxation time). We also show that the presence of a
resonant mode in the quantum bath can impede the dynamic transition when the
resonant frequency is of the order of the qubit gap. Our results are obtained
by a numerical calculation of the finite time and the asymptotic stationary
population of the qubit states, using the Floquet-Markov approach to solve a
realistic model of the flux qubit considering up to 10 energy levels.Comment: One new figure added. Final version to be published in PR
Caractérisation de piÚces métalliques à différentes étapes du procédé de mise en peinture par poudrage
Notre projet MĂ©tiers de 3Ăšme annĂ©e sâinscrit dans le cadre des projets Ateliers Transfert Innovation (ATI). Notre sujet rĂ©sulte de la demande dâun industriel et son intitulĂ© a Ă©tĂ© dĂ©fini suite Ă la rencontre de Monsieur Jean-Pierre Caquel, directeur de la sociĂ©tĂ© Europoudrage et Madame Delphine Veys-Renaux, maĂźtre de ConfĂ©rences Ă lâUniversitĂ© de Lorraine. Le but de ce projet, pour nous Ă©tudiants, Ă©tait de traiter la problĂ©matique du bullage lors de la cuisson des peintures poudres. Notre problĂ©matique concerne le phĂ©nomĂšne de dĂ©gazage qui survient principalement lors de la cuisson des peintures poudre aprĂšs application sur les piĂšces. Notre but a Ă©tĂ© de dĂ©terminer si lâĂ©tape dâĂ©tuvage est indispensable et quelle seraient les moyens possibles pour lâĂ©viter car elle est trĂšs onĂ©reuse. Lâobjectif est Ă©galement de dĂ©terminer lâimpact du substrat sur lâapparition du phĂ©nomĂšne de bullage et dâĂ©tablir des solutions pour le minimiser voire mĂȘme lâĂ©liminer. La caractĂ©risation dâalliages dâaluminium a permis dâanalyser les potentielles causes de lâapparition du phĂ©nomĂšne de bullage.
Nous avons dans un premier temps pris contact avec diffĂ©rentes entreprises et prĂ©parĂ© une liste des Ă©chantillons que nous souhaitions obtenir. Nous avons dĂ©terminĂ© les diffĂ©rentes Ă©tapes du procĂ©dĂ© que chaque Ă©chantillon devait subir. Ce choix a pu se faire principalement Ă lâaide des recherches bibliographiques effectuĂ©es par le groupe ATI de lâannĂ©e derniĂšre (2014-15) qui a rĂ©ussi Ă dĂ©terminer lâinfluence des diffĂ©rentes Ă©tapes du procĂ©dĂ© de mise en peinture sur lâapparition du bullage. Notre projet est Ă©galement nĂ© en partie grĂące Ă eux car ils ont dĂ©terminĂ© que le substrat jouait un rĂŽle important dans lâapparition du phĂ©nomĂšne de bullage.
Une fois les Ă©chantillons traitĂ©s par les entreprises collaboratrices au projet, nous avons eu la chance de pouvoir Ă©tudier ceux-ci Ă lâaide dâun microscope optique et surtout un Microscope Electronique Ă Balayage fonctionnant Ă trĂšs faible tension (jusque 1kV), ce qui a permis de voir lâextrĂȘme surface de nos Ă©chantillons et dâanalyser lâinterface peinture-substrat de maniĂšre trĂšs fine. Pour cela, une prĂ©paration antĂ©rieure de nos Ă©chantillons Ă©tait nĂ©cessaire. Nous avons donc dĂ©coupĂ©, mis en rĂ©sine et poli les Ă©chantillons dâĂ©tude avant de les Ă©tudier au MEB.
Nous avons Ă©galement pu visiter les entreprises et visualiser Ă Ă©chelle rĂ©elle les lignes de production dâapplication de la peinture en poudre. LâĂ©change avec les entreprises a permis de confirmer certaines hypothĂšses et Ă©galement de proposer de nouvelles pistes. Malheureusement, nous nâavons pu Ă©tudier tous les types de mĂ©taux et cette Ă©tude sera portĂ©e exclusivement sur lâaluminium. Nous aurions bien aimĂ© pouvoir effectuer des comparaisons entre deux types de mĂ©taux car dâaprĂšs le retour que nous avons eu des entreprises, les mĂ©taux ferreux sont plus sujets Ă lâapparition du phĂ©nomĂšne de bullage. Cela aurait Ă©tĂ© lâoccasion de pouvoir affirmer que cela est vrai, ainsi que de dĂ©terminer pourquoi ce type de substrat est plus sujet au bullage

A history of changes in the policies and practices of second language programs in the public schools of Clark County, Las Vegas, Nevada
A History of Changes in the Policies and Practices of Second Language Programs in the Public Schools of Clark County, Las Vegas, Nevada is an historical study that traced the development of Second Language Programs in the Clark County School District, Las Vegas, Nevada. The research study examined national and federal actions which served as the bases for the initial implementation of Second Language Programs (1880-1998), historical sequential activities in Nevada that contributed to the implementation of Second Language Programs in the state, and the sequential activities that specifically dealt with the development of Second Language Programs in the Clark County School District (1968-1998). Included in the study is an historical examination of these sequential activities and the time periods in which they took place
