Gorycz wina : o wierszu "Colas Breugnon" Jerzego Lieberta
No full textIn an interpretative essay devoted to a poem by Jerzy Liebert Colas Breugnon, the
author of the article searches for the signs of affirmation, which – as it seems – should
permeate into the poem by means of intertextual dialogue. Such a dialogue is held with
a famous novel by Romain Rolland, considered as a manifesto of life optimism. The
relation that seems to have conjoined these two texts is less obvious than one could
think. A figure of Colas Breugnon served Liebert not only to demonstrate the eulogy
of life in all its positive aspects but also to point to the hardships in one’s faith in God
that required from man the acceptance of also those experiences that are beyond the
delights of life
Cent ans de pratique associative : un point de vue juridique (IIe partie)
No full textSoulignant l’hétérogénéité du monde associatif, Colas Amblard s’interroge sur la pertinence du statut associatif pour accueillir des entreprises de l’économie sociale et sur l’opportunité de réformer la loi de 1901. L’auteur entreprend de spécifier ce qui réunit les associations : le droit associatif est une liberté publique, l’association est, juridiquement, un contrat et, enfin, l’évolution actuelle des pratiques associatives définit un véritable droit de l’entreprise associative. En s’appuyant sur la jurisprudence, l’administration a en effet produit une « doctrine des oeuvres » (1977) qui définit les conditions de la non-lucrativité. Plus récemment, l’évolution de la fiscalité a permis l’établissement d’un traitement différencié, qui résout, au moins en partie, les problèmes que l’essor de l’entreprise associative pose à la loi de 1901. La prise en compte du « mieux disant » social reste pour l’instant problématique.Emphasizing the diversity of the non-profit sector, Colas Amblard questions the relevance of the non-profit legal form for social-economy firms and whether it is time to revise the 1901 law governing associations. In attempting to identify what unites associations, the author observes that the right to form an association is a civil liberty, that an association is a legal contract and, lastly, that the current evolution of non-profit practice has produced a body of law on non-profit enterprises. Based on precedents, the government defined the requirements for qualifying as a non-profit organization in 1977. More recently, changes in taxation have made it possible to treat individual cases differently, which at least partially resolves the problems posed by the growth of non-profit enterprises with respect to the 1901 law. Taking into account social value-added remains for the moment problematic
The impact of social subordination on stress reactivity and cognitive abilities in CD-1 outbred mice
No full textImposed social subordination, such as that acquired through defeat or alienation, has been shown to negatively impact cognitive performance in both human and animal populations. In the present study we examined whether domain-specific and/or domain- general learning abilities (c.f. general intelligence) are differentially influenced by the imposition of social subordination. Further, we examined whether any observable differences in learning abilities were the direct result of subordination or if they represented deficits which are intrinsically expressed in individuals that are innately disposed to subordination. Subordinate and dominant behaviors were assessed in two groups of CD-1 male mice. In one group (IMP), social stratification occurred prior to the assessment of learning abilities, while in a second group (INN), this assessment occurred after learning abilities were measured. Domain-specific learning abilities were measured as performance on individual learning tasks while domain-general learning abilities were measured as the aggregate performance across a battery of learning tasks. We found that the imposition of subordination decreases exploratory tendencies and to some degree affects domain-specific learning performance. However, the most staggering results came in our analysis of general learning abilities whereby we observed that subjects who assumed a submissive role prior to the assessment of cognitive function were severely impaired. Similar decrements were not seen in subjects that were determined to be subordinate after learning had been assessed. The latter finding indicates that absent the imposition of subordination, individuals with subordinate tendencies do not demonstrate learning impairments. This observation could have important ramifications for those who suffer bullying in school or workplace settings.Ph.D.Includes bibliographical referencesIncludes vitaby Danielle C. Cola

On the interaction between the ion cyclotron resonance heating and scrape-off layer turbulence via coherent waves
No full textIt was reported on the ASDEX-Upgrade tokamak and recently confirmed on the Tore Supra tokamak (Antar 2010 et al Phys. Rev. Lett. 105 165001, Antar 2012 Nucl. Fusion 52 103005) that ion cyclotron resonance heating (ICRH) reduces turbulence in the scrape-off layer (SOL) by strongly affecting the large intermittent structures. In this paper, and for the first time, we show that ICRH, with a frequency at 57MHz, excites waves at frequencies about 1.7MHz as a consequence of parametric decay instability. This is reflected in the power spectra of the ion saturation signals, measured by fixed Langmuir probes acquired at 200MHz, as well as in the cross-correlation between two toroidally distanced probes and in the bicoherence spectra. The velocity and the wavenumber of this perturbation is determined indicating that they may be ion sound waves. Furthermore, it is shown that they are nonlinearly coupled to the turbulent fluctuations leading to the strong modification of the power spectrum and could provide explanations about the decrease in the level of turbulence in the SOL during ICRH. This aspect is reflected in the enhanced three-wave coupling between these waves and turbulence studied by applying the bispectral analysis. Turbulence appears thus to be affected when ICRH is applied by the intermediate of ion sound waves. © 2014 EURATOM.Antar G, 2010, PHYS REV LETT, V105, DOI 10.1103-PhysRevLett.105.165001; Antar GY, 2007, PHYS PLASMAS, V14, DOI 10.1063-1.2424886; Antar GY, 2003, PHYS PLASMAS, V10, P419, DOI 10.1063-1.1536166; Antar GY, 2001, PHYS PLASMAS, V8, P1612, DOI 10.1063-1.1363663; Antar GY, 2001, PHYS REV LETT, V87, DOI 10.1103-PhysRevLett.87.065001; Antar GY, 2012, NUCL FUSION, V52, DOI 10.1088-0029-5515-52-10-103005; Bobkov VV, 2010, NUCL FUSION, V50, DOI 10.1088-0029-5515-50-3-035004; BORA D, 1991, NUCL FUSION, V31, P2383, DOI 10.1088-0029-5515-31-12-010; BURES M, 1988, PLASMA PHYS CONTR F, V30, P149, DOI 10.1088-0741-3335-30-2-004; Colas L, 2007, J NUCL MATER, V363, P555, DOI 10.1016-j.jnucmat.2006.12.052; Colas L, 2007, PLASMA PHYS CONTR F, V49, pB35, DOI 10.1088-0741-3335-49-12B-S02; Cziegler I, 2012, PLASMA PHYS CONTR F, V54, DOI 10.1088-0741-3335-54-10-105019; Fenzi C, 2011, NUCL FUSION, V51, DOI 10.1088-0029-5515-51-10-103038; GALVAO RMO, 1994, PLASMA PHYS CONTR F, V36, P1679, DOI 10.1088-0741-3335-36-10-007; HASEGAWA A, 1977, PHYS REV LETT, V39, P205, DOI 10.1103-PhysRevLett.39.205; HEIKKINEN JA, 1989, NUCL FUSION, V29, P1307, DOI 10.1088-0029-5515-29-8-007; HOFMANN JV, 1990, FUSION ENG DES, V12, P185, DOI 10.1016-0920-3796(90)90078-K; Milligen B.P.V., 1995, PHYS REV LETT, V74, P395; MORISAKI T, 1995, PLASMA PHYS CONTR F, V37, P787, DOI 10.1088-0741-3335-37-7-008; Nieuwenhove R.V., 1989, J NUCL MATER, V162-164, P288; NOTERDAEME JM, 1993, PLASMA PHYS CONTR F, V35, P1481, DOI 10.1088-0741-3335-35-11-001; Oost G.V., 1990, FUSION ENG DES, V12, P149; PINSKER RI, 1992, AIP CONF PROC, V244, P105; RITZ CP, 1989, PHYS FLUIDS B-PLASMA, V1, P153, DOI 10.1063-1.859082; RITZ CP, 1986, PHYSICA D, V20, P320, DOI 10.1016-0167-2789(86)90036-9; SAMM U, 1987, PLASMA PHYS CONTR F, V29, P1321, DOI 10.1088-0741-3335-29-10A-313; STENZEL RL, 1988, PHYS REV LETT, V60, P704, DOI 10.1103-PhysRevLett.60.704; Stix T.

"Donde se descomponen las colas de los burros" de Carolina Vivas. La Antígona latinoamericana del siglo XXI: no es el dolor de una, es el dolor de todas.
No full textIn this article we will analyze the play Donde se descomponen las colas de los burros by the playwright Carolina Vivas, which can be read as a reception of the tragedy Antigone. In this sense, we are interested in presenting the transformation of the character and the argument in the Latin American context, to visualize how the previous appropriation of the classic text in the continent influences the work of the Colombian author and, at the same time, to highlight the elements of the tragedy that the author rescues and modifies. Also, we will present a trend of the various readings and receptions of Antigone, emphasizing those carried out in Latin America. We will analyze this elements to situate the place from where the rewriting of Carolina Vivas is located and presented as a piece that, due to the way in which it rewrites the plot and the figure of Antigone, is configured as a milestone in the already extensive tradition of receptions of the Sophoclean tragedy in our continent.En el presente artículo analizaremos la obra Donde se descomponen las colas de los burros de la dramaturga Carolina Vivas, la que puede ser leída como una recepción de la tragedia Antígona. En este sentido, nos interesa presentar la transformación del personaje y su argumento en el contexto latinoamericano, para visualizar cómo la apropiación previa del texto clásico en el continente influye en la obra de la autora colombiana y, a su vez, para destacar los elementos de la tragedia que ella rescata y modifica. Para esto presentaremos un recorrido por diversas las lecturas y recepciones de Antígona, enfatizando las realizadas en Latinoamérica. Estudiaremos todo lo anterior para circunscribir el lugar desde donde se sitúa la reescritura de Carolina Vivas y pensarla como una pieza que, debido a la particular forma en que reescribe el argumento y la figura de Antígona, se configura como un hito en la ya extensa tradición de recepciones de la tragedia de Sófocles en nuestro continente
The role of power and magnetic connection to the active antenna in the suppression of intermittent structures by ion cyclotron resonance heating
No full textThe effect of the ion cyclotron resonance heating (ICRH) on the scrape-off layer (SOL) is still an open issue, where, lately it was shown on the ASDEX-Upgrade tokamak that turbulence large-scale structures, known as blobs or avaloids, are suppressed by ICRH [G. Antar et al. Phys. Rev. Lett. 2010]. On the Tore Supra tokamak, we confirm that the ICRH suppresses large-scale structures while small-scale structures are enhanced; Overall, the turbulence level of fluctuations is reported to drop from about 40percent to 25percent. The dependence on the ICRH power showed that if a threshold existed it would be below 500 kW and that above this power, no additional effects on the SOL turbulence are reported. The other study reported in this article deals with the importance of the magnetic field line connections or, in other words, whether the interaction between ICRH and turbulence is global, affecting the whole plasma, or local affecting regions that are magnetically connected to the active antenna. We found that the toroidal connection to the active antenna is not critical in the sense that turbulence in regions close to the antenna but not necessarily connected are still affected. For regions that are not connected and far from the active antenna, turbulence does not change much when applying ICRH. © 2014 AIP Publishing LLC.Antar G, 2010, PHYS REV LETT, V105, DOI 10.1103-PhysRevLett.105.165001; Antar GY, 2003, PHYS PLASMAS, V10, P419, DOI 10.1063-1.1536166; Antar GY, 2001, PHYS REV LETT, V87, DOI 10.1103-PhysRevLett.87.065001; Antar GY, 2008, PLASMA PHYS CONTR F, V50, DOI 10.1088-0741-3335-50-9-095012; Bobkov VV, 2010, NUCL FUSION, V50, DOI 10.1088-0029-5515-50-3-035004; Colas L, 2007, PLASMA PHYS CONTR F, V49, pB35, DOI 10.1088-0741-3335-49-12B-S02; HOFMANN JV, 1990, FUSION ENG DES, V12, P185, DOI 10.1016-0920-3796(90)90078-K; LEHRMAN IS, 1990, PLASMA PHYS CONTR F, V32, P51, DOI 10.1088-0741-3335-32-1-005; MORISAKI T, 1995, PLASMA PHYS CONTR F, V37, P787, DOI 10.1088-0741-3335-37-7-008; Myra JR, 2006, NUCL FUSION, V46, pS455, DOI 10.1088-0029-5515-46-7-S08; NOTERDAEME JM, 1993, PLASMA PHYS CONTR F, V35, P1481, DOI 10.1088-0741-3335-35-11-001; Pericoli-Ridolfini V., 2011, NUCL FUSION, V51; TFR Group, 1984, PLASMA PHYS CONTROL, V26, P1141; van Milligen BP, 2005, PHYS PLASMAS, V12, DOI 10.1063-1.1884615; VANOOST G, 1990, FUSION ENG DES, V12, P149, DOI 10.1016-0920-3796(90)90075-H0

On the Tore Supra tokamak, we confirm that the ICRH suppresses large-scale structures while small-scale structures are enhanced; overall, the turbulence level of fluctuations is reported to drop from about 40percent to 25percent. This confirms that the effects on turbulence are independent of the type of plasma confinement, L-mode on Tore Supra versus H-mode on ASDEX-Upgrade. The dependence on the ICRH power showed that if a threshold existed it would be below 500kW and that above this power, no additional effects on the SOL turbulence are reported. The other study reported in this paper deals with the importance of the magnetic field line connections or, in other words, whether the interaction between ICRH and turbulence is global, affecting the whole plasma, or local, affecting regions that are magnetically connected to the active antenna.

Community beyond knowledge: The figures of boundary and flight in refugee narratives.
No full textThis dissertation focuses on the stories of refugees fleeing Central America through the US to Canada as these appear in legal documents (Personal Information Forms or PIFs) and as recalled by the author's experience of working in the preparation of these documents as an interpreter. These PIFs contrast with published testimonials such as that of Rigoberta Menchu. Whereas the latter function as speech acts in an ongoing political struggle the PIFs function as a legal instrument of flight and the end of political struggle. Considering these PIFs as a form of storytelling the author focuses a discussion of them around the question, How do you tell a story that does not trap you? To do this the PIFs are surrounded with other stories and theoretical discussions about the coming about of the conditions that make their telling necessary and the space through which these flights take place. The author uses a mixed form narrative that sets stories next to essays and legal documents. In this way there is a textual mimicking of the content of the dissertation through the creation of textual borders. This stylistic maneuver heightens the salience of certain elements of each type of text by creating a stark contrast with its neighboring texts. The discussion of PIFs places them in the context of a discussion about communities, borders, knowledge and capital. There is a gestalt perceptual shift created by the continuous movement between the very local, or micro-level, (the refugee claim documents, Diego Rivera's Detroit Industry murals) and the macro-level (the politics of border patrols, international labor markets). The author argues against the still persistent prejudice for transcendental groundings of knowledge and points up how knowledge and community must inevitably make recourse to the local. Whereas some metaphors contribute to this transcendentalist tendency (mind's eye, tree of knowledge) the author suggests epistemological metaphors (rhizomes, language communities) which open up a field of play (and space for ethics) in a discussion of these issues.PhDAmerican studiesLanguage, Literature and LinguisticsLatin American literaturePhilosophyPhilosophy, Religion and TheologySocial SciencesUniversity of Michigan, Horace H.

Elaboration of glass-ceramic materials for emission properties in the infrared range
No full textLes vitrocéramiques sont des matériaux composites innovants constitués de particules cristallines dispersées dans une matrice vitreuse et qui combinent les avantages du verre avec les propriétés spécifiques de la phase cristalline, en particulier des rendements quantiques élevés. Ces matériaux composites sont donc de plus en plus étudiés afin d’élaborer de nouvelles sources d’émission pour les lasers pour des applications dans le domaine des télécommunications, du médical, de la défense ou de l’aéronautique et spatial. La méthode d’incorporation directe de cristaux dans les verres a été développée pour pallier les inconvénients de la méthode traditionnelle de dévitrification. Cependant, les défis relatifs à cette voie de préparation sont de réussir à combiner survie et bonne dispersion des cristaux dans le verre.Dans ce travail de thèse, des particules de niobate d’yttrium dopées avec des éléments terres rares (europium ou holmium) ont été préparées par coprécipitation. Les particules ont été incorporées dans trois types de matrices vitreuses (phosphates, tellurites et chalcogénures) afin d’étudier l’influence de la composition chimique de la matrice hôte sur la survie des particules. Deux voies d’élaboration des vitrocéramiques composites ont été effectuées : la fusion-trempe traditionnelle et le frittage SPS.Glass-ceramics are innovative composite materials composed by dispersed crystalline particles within a glass matrix that combines the benefits of glass with the specific properties of the crystalline phase, especially high quantum yields. Therefore, such composite materials are increasingly investigated in order to develop new laser emission sources for telecommunications, medical, defense or aerospace fields. The direct incorporation of crystals into glasses was developed to overcome the disadvantages of the traditional devitrification method. However, the challenges related to this preparation route are to combine the survival and the good dispersion of the particles into the glass.In this thesis, yttrium niobate particles doped with rare earth elements (europium or holmium) were prepared by co-precipitation. The particles were incorporated into three types of glasses (phosphates, tellurites and chalcogenides) in order to study the influence of the host matrix chemical composition on the particles survival. Two processing routes were performed to prepare the glass-ceramics: traditional melt-quenching and SPS sintering
