Effect of thermal exposure on the microstructure of the interface in a Grf/Al composite
Authors: Wang Pingping , Chen Guoqin , Jiang Longtao , Li Daguang , Wu Gaohui
Published: April 2015

The microstructure of the interface in a Grf/Al composite after exposure at high temperature was investigated. The graphite fiber reinforced aluminum matrix composite was prepared by the pressure infiltration method. After being heat treated at 550°C, 600°C and 640°C for different times, the microstructure of the interface in the composite was studied by using transmission electron microscopy (TEM). Furthermore, the content of Al4C3 in the interface was examined using X-ray diffraction (XRD). The results showed that not only the micro morphology but also the content of Al4C3 in the interface varied with the increase in temperature. When the composite was heat treated at 550°C and 600°C, Al4C3 with a big length-to-diameter ratio was observed in the interface, while Al4C3 with a small length-to-diameter ratio was found when the heat treatment temperature was 640°C. With the increase in the time, the content of Al4C3 in the interface increased rapidly when the composite was heat treated at 640°C. Based on the dynamic calculation, the interface reaction diffusion rate constant of the Grf/Al composite increases rapidly when the temperature is higher than 600°C.
Campaign-Personalization and Constituency Focus in a Mixed-Member Electoral System. The Case of Hungary
Authors: Papp Zsófia
Published: April 2015

The aim of this paper is to uncover the micro-factors structuring campaign personalization in the case of Hungarian Members of Parliament. It is presumed that in a party-centred environment, the effects of the various independent characteristics are filtered by the parties. Thus, due to the electoral rules, personalization cannot contradict party centeredness. Representatives do not wish to distance themselves from their parties. Personalization is more of the result of the positions they hold or wish to fill in than the desire to defy party lines out of individualistic motivations. Based on the data from the 2010 MP-survey of the Hungarian Election Study, the article unveils the circumstances under which campaign personalization prevails. The international scholarly literature sets several hypotheses with regards to the factors influencing three dimensions of campaign personalization (norms, means and agenda), out of which several will be tested in this article. The analysis concludes that even under party-centred circumstances, the role of individual motivations and habits cannot be overlooked in defining the degree of personalization, nevertheless the interpretation of such effects requires caution.
Critical Analysis of Civil Service Politicization in Slovenia
Authors: Čehovin Marko , Haček Miro
Published: April 2015

Even though some level of politicization is pressed into the “genetic material” of administrative systems, the majority of experts agree that a system with high levels of politicization is less efficient, as most individuals do not have the chance to develop their full potential. The weaknesses of politicization are even more devastating in smaller states such as Slovenia, as they have a limited amount of human resources available. Based on a detailed analysis of the politicization of civil service in Slovenia, the authors can confirm that the level of politicization is quite high. After accession into the European Union (2004) and the adoption of austerity laws (2010–2013), politicization increased even further. Despite the formal existence of a meritocratic civil service system, politicians have an increasingly decisive role in the employment and advancement of civil servants, and total control over the appointment and dismissal of senior civil servants. The authors conclude that the predominance of politicians with relationships to senior civil servants can be changed with relatively simple adjustments to formal acts.
Solving surface and embedded structures without Fourier inversion: a 2-dimensional direct space approach
Authors: Kirfel Armin , Fischer Karl
Published: April 2015

Two-dimensional equal atom structures or structure projections are determined applying the parameter space concept, either directly or supported by coordinate indications obtained from one or two separate runs on 1-d projection(s). By-passing the “phase problem” a grid-search based trial and error technique is used for optimizing model vs. experimental quasi-normalized structure amplitudes (or intensities) of a small number of reflections. The concept can also be applied to multi-wavelengths X-ray data exhibiting resonant scattering contrasts as well as to neutron data from structures including elements with differing signs of scattering powers. Unique results (or all possible combinations of atom sites meeting the data) are obtained from rather few reflections. They provide remarkable spatial resolution, but much more computing power is needed than for standard techniques. Considering the numbers of test models to be checked as a relative measure of computing time the computational efforts for different solution options and increasing numbers of independent atoms are assessed. In the examples given for symmetry
p1
, where one atom defines the origin, up to 8 additional atoms were located within Δ(x, y) ≤ 0.025 from, e.g., 12 reflections with randomly generated maximum relative intensity errors of up to 20 %. All calculations were carried out with a standard PC.
Crystal chemical models for the cancrinite-sodalite supergroup: the structure of a new 18-layer phase
Authors: Bonaccorsi Elena , Nazzareni Sabrina
Published: April 2015

The framework of the minerals belonging to the cancrinite-sodalite supergroup is very flexible and adapts itself to a wide range contents of extra-framework anions, giving rise to complex structures with different stacking sequences of layers that contain six-membered rings of tetrahedra. The knowledge of the crystal chemistry of these minerals was the key for the structure solution of a new phase showing a sequence with 18 layers. Geometrical and chemical constraints were imposed to the positions of the six-member rings so limiting the number of possible non-equivalent sequences of the 18 layers. The more probable sequences were single out on the basis of the chemical data and used as starting model vs. single crystal X-ray intensity data. The new 18-layer phase, ideal chemical formula (Na, K, Ca)72(Si54Al54O216)(SO4)16(Cl, H2O)8, Z = 1, space group P3, a = 12.904(2) Å, c = 47.802(4) Å, displays a stacking sequence ABCABACACABABACABC, Zdhanov symbol (8)211(2)112. The examined crystal was found in the sample MMUR (Museo di Mineralogia dell’Università di Roma “La Sapienza”) 24320, associated with sacrofanite, which is the 28-layer member of the supergroup. The sample was collected at Sacrofano, (Latium, Italy) in a volcanic ejected block, which originated from a pneumatolitic-pyroclastic explosion.
Synthesis, molecular and supramolecular structure of a new dinuclear aluminium(III) complex derived from 3-aminopyrazine- 2-carboxylic acid
Authors: Hazra Susanta , Karmakar Anirban
Published: April 2015

Solvothermal reaction of aluminum(III) nitrate nonahydrate with 3-aminopyrazine-2-carboxylic acid (HL) gave rise to a bis(μ2-hydroxo)-tetrakis(3-aminopyrazine-2-carboxylato)-dialuminium(III) complex [Al(L)2(OH)]2 (1) (L = 3-aminopyrazine-2-carboxylate). Crystal structure analysis reveals that each hexacoordinated Al(III) centre adopts a distorted octahedral geometry occupied by two Ocarboxylate, two Npyrazine and two Ohydroxo atoms. The L– ligand binds the metal cation by means of one pyrazine N-atom and carboxylate O-atoms via chelating fashion. Two hydroxo groups bridge between two aluminum(III) centres, assisting to construct a dinuclear structure. In the crystal lattice of 1 two symmetry non-equivalent dinuclear complexes are present. A 3D supramolecular associate in the crystal lattice of 1 has been stabilized by a number of non-covalent H-bonding interactions. Topology of the hydrogen bonded network has been also analyzed.

Pyrazoles 4a–f, hydrazones 5a–c and 6a–c, pyrazolo[1,5-a]pyrimidines 7a, b, and pyrazolo[3,4-b]pyridine 8 were prepared in good yields (80–95 %) from the reaction of 6-substituted (H, Me, F) 3-formylchromones 1a–c with N-substituted hydrazines 2a–c and aminopyrazole 3. The cytotoxicity of the synthesized compounds was assessed through the brine shrimp lethality assay. IC50 values were between 80 and 300 μm. Fluorine substitution decreased IC50 values.
Body fatness as a cause of cancer: epidemiologic clues to biologic mechanisms
Authors: Byers Tim , Sedjo Rebecca L
Published: April 2015

Carrying excess body fat is a leading cause of cancer. Epidemiologic evidence gives strong clues about the mechanisms that link excess adiposity to risk for several cancer sites. For postmenopausal breast cancer and endometrial cancer, the hyper-estrogenic state that is induced by excess body fatness is the likely cause. For esophageal cancer and gallbladder cancer, chronic local inflammation induced by acid reflux and gallstones is the likely cause, and for liver cancer, local inflammation induced by hepatic fatty infiltration is the likely cause. However, for several other cancers known to be associated with excess adiposity, including cancers of the colon, pancreas, ovary, kidney, and prostate, specific causes are not known. Possible candidates include elevated systemic or local tissue inflammation induced by adiposity and effects of the elevated levels of leptin, insulin, IGFs, and depressed immune function that are seen with excess adiposity. There is growing evidence that intentional weight loss not only reduces circulating levels of cancer-associated factors but that it also reduces cancer incidence and recurrence. Better research is needed to understand the mechanisms that link excess body fat to cancer risk as well as to understand the amount of weight loss needed for substantial cancer risk reduction. Finally, as we develop better understanding of the mediators of the effects of excess body fatness on cancer risk, we should identify pharmacologic interventions that target those mediators so that they can be used to complement weight loss in order to reduce cancer risk.

Published: April 2015

The surgical treatment of some odontogenic tumors often leads to tooth and maxillary bone loss as well as to facial deformity. Therefore, the identification of genes involved in the pathogenesis of odontogenic tumors may result in alternative molecular therapies. ThePRKAR1Agene displays a loss of protein expression as well as somatic mutations in odontogenic myxomas, an odontogenic ectomesenchymal neoplasm. We used a combination of quantitative RT-PCR (qRT-PCR), immunohistochemistry, loss of heterozygosity (LOH) analysis, and direct sequencing of allPRKAR1Aexons to assess if this gene is altered in mixed odontogenic tumors. Thirteen tumors were included in the study: six ameloblastic fibromas, four ameloblastic fibro-odontomas, one ameloblastic fibrodentinoma, and two ameloblastic fibrosarcomas. The epithelial components of the tumors were separated from the mesenchymal by laser microdissection in most of the cases. We also searched for odontogenic pathology inPrkar1a+/−mice.PRKAR1AmRNA/protein expression was decreased in the benign mixed odontogenic tumors in association with LOH at markers around thePRKAR1Agene. We also detected a missense and two synonymous mutations along with two 5′-UTR and four intronic mutations in mixed odontogenic tumors.Prkar1a+/−mice did not show evidence of odontogenic tumor formation, which indicates that additional genes may be involved in the pathogenesis of such tumors, at least in rodents. We conclude that thePRKAR1Agene and its locus are altered in mixed odontogenic tumors.PRKAR1Aexpression is decreased in a subset of tumors but not in all, andPrkar1a+/−mice do not show abnormalities, which indicates that additional genes play a role in this tumor's pathogenesis.
Carnosine decreases IGFBP1 production in db/db mice through suppression of HIF-1
Authors: Forsberg Elisabete A , Botusan Ileana R , Wang Jing , Peters Verena , Ansurudeen Ishrath , Brismar Kerstin , Catrina Sergiu Bogdan
Published: April 2015

IGF binding protein 1 (IGFBP1) is a member of the binding proteins for the IGF with an important role in glucose homeostasis. Circulating IGFBP1 is derived essentially from the liver where it is mainly regulated negatively by insulin. Carnosine, a natural antioxidant, has been shown to improve metabolic control in different animal models of diabetes but its mechanisms of action are still not completely unraveled. We therefore investigate the effect of carnosine treatment on the IGFBP1 regulation in db/db mice. Db/db mice and heterozygous non-diabetic mice received for 4 weeks regular water or water supplemented with carnosine.Igfbp1mRNA expression in the liver was evaluated using qPCR and the protein levels in plasma by western blot. Plasma IGF1 and insulin were analyzed using immunoassays. HepG2 cells were used to study thein vitroeffect of carnosine on IGFBP1. The modulation of hypoxia inducible factor-1 alpha (HIF-1α) which is the central mediator of hypoxia-induction of IGFBP1 was analyzed using: WB, reporter gene assay and qPCR. Carnosine decreased the circulating IGFBP1 levels and the liver expressionIgfbp1, through a complex mechanism acting both directly by suppressing the HIF-1α-mediated IGFBP1 induction and indirectly through increasing circulating insulin level followed by a decrease in the blood glucose levels and increased the plasma levels or IGF1. Reduction of IGFBP1 in diabetes through insulin-dependent and insulin-independent pathways is a novel mechanism by which carnosine contributes to the improvement of the metabolic control in diabetes.

Published: April 2015

BACKGROUND AND OBJECTIVES:

Despite previous studies demonstrating no difference in mortality or morbidity, the various surgical approaches for necrotizing enterocolitis (NEC) in infants have not been evaluated economically. Our goal was to compare total in-hospital cost and mortality by using propensity score–matched infants treated with peritoneal drainage alone, peritoneal drainage followed by laparotomy, or laparotomy alone for surgical NEC.

METHODS:

Utilizing the California OSHPD Linked Birth File Dataset, 1375 infants with surgical NEC between 1999 and 2007 were retrospectively propensity score matched according to intervention type. Total in-hospital costs were converted from longitudinal patient charges. A multivariate mixed effects model compared adjusted costs and mortality between groups.

RESULTS:

Successful propensity score matching was performed with 699 infants (peritoneal drainage, n = 101; peritoneal drainage followed by laparotomy, n = 172; and laparotomy, n = 426). Average adjusted cost for peritoneal drainage followed by laparotomy was $398 173 (95% confidence interval [CI]: 287 784–550 907), which was more than for peritoneal drainage ($276 076 [95% CI: 196 238–388 394]; P = .004) and similar to laparotomy ($341 911 [95% CI: 251 304–465 186]; P = .08). Adjusted mortality was highest after peritoneal drainage (56% [95% CI: 34–75]) versus peritoneal drainage followed by laparotomy (35% [95% CI: 19–56]; P = .01) and laparotomy (29% [95% CI: 19–56]; P < .001). Mortality for peritoneal drainage was similar to laparotomy.

CONCLUSIONS:

Propensity score–matched analysis of surgical NEC treatment found that peritoneal drainage followed by laparotomy was associated with decreased mortality compared with peritoneal drainage alone but at significantly increased costs.

Authors: Davis Kelly D. , Lawson Katie M. , Almeida David M. , Kelly Erin L. , King Rosalind B. , Hammer Leslie , Casper Lynne M. , Okechukwu Cassandra A. , Hanson Ginger , McHale Susan M.
Published: April 2015

OBJECTIVES:

In the context of a group randomized field trial, we evaluated whether parents who participated in a workplace intervention, designed to increase supervisor support for personal and family life and schedule control, reported significantly more daily time with their children at the 12-month follow-up compared with parents assigned to the Usual Practice group. We also tested whether the intervention effect was moderated by parent gender, child gender, or child age.

METHODS:

The Support-Transform-Achieve-Results Intervention was delivered in an information technology division of a US Fortune 500 company. Participants included 93 parents (45% mothers) of a randomly selected focal child aged 9 to 17 years (49% daughters) who completed daily telephone diaries at baseline and 12 months after intervention. During evening telephone calls on 8 consecutive days, parents reported how much time they spent with their child that day.

RESULTS:

Parents in the intervention group exhibited a significant increase in parent-child shared time, 39 minutes per day on average, between baseline and the 12-month follow-up. By contrast, parents in the Usual Practice group averaged 24 fewer minutes with their child per day at the 12-month follow-up. Intervention effects were evident for mothers but not for fathers and for daughters but not sons.

CONCLUSIONS:

The hypothesis that the intervention would improve parents’ daily time with their children was supported. Future studies should examine how redesigning work can change the quality of parent-child interactions and activities known to be important for youth health and development.
Breastfeeding Assessment Score: Systematic Review and Meta-analysis
Authors: Raskovalova Tatiana , Teasley Susan L. , Gelbert-Baudino Nathalie , Mauri Paola Agnese , Schelstraete Camille , Massoutier Maximillien , Berger Marc , François Patrice , Labarère José
Published: April 2015

BACKGROUND:

Previous studies have revealed conflicting results for the Breastfeeding Assessment Score (BAS) in predicting early breastfeeding cessation. Our objective was to externally validate the BAS and provide summary accuracy estimates for this clinical prediction model.

METHODS:

We used the original data from a prospective cohort study. Additional studies were identified by searching electronic databases (Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane) from 2002 to 2013 and contacting research groups that had derived or validated the BAS. Prospective cohort studies were eligible if the BAS was computed at baseline and mothers were followed up for breastfeeding cessation. Two physicians extracted relevant information and independently assessed the methodological quality for the included studies.

RESULTS:

In the external validation cohort, 22 of 424 mothers (5.2%) discontinued breastfeeding within 14 days of infant age. The BAS predicted early breastfeeding cessation with an area under the curve of 0.70 (95% confidence interval [CI]: 0.65 to 0.74) and inadequate calibration. When restricting the meta-analysis to 3169 mother–infant pairs enrolled in 4 higher-quality studies, a BAS value <8 predicted early cessation with 0.80 sensitivity (95% CI: 0.69 to 0.91) and 0.51 specificity (95% CI: 0.32 to 0.70) summary estimates.

CONCLUSIONS:

Substantial between-study heterogeneity limited the interpretation of summary accuracy estimates. The BAS predicts early breastfeeding cessation with moderate accuracy, although local recalibration is advised before implementation. Further study is warranted to determine whether the BAS can help pediatricians in identifying mother–infant pairs that may benefit from more extensive breastfeeding assessment and support.

Optical Phonon Modes and Electron-optical Phonon Interaction in Core-shell Semiconductor Quantum Wires
Authors: Dat Nguyen Nhu , Hai Le Thanh
Published: April 2015

Within the framework of the macroscopic dielectric continuum model the longitudinal optical (LO) phonon modes are derived for a cylindrical semiconductor quantum wire made of semiconductor 1 (well material) embedded in another finite semiconductor 2 (barrier material).  The phonon states of modes are given by solving the generalized Born-Huang equation. It is shown that there may exist four types of longitudinal optical phonon modes according to the concrete materials forming the wire. The dispersion equations for phonon frequencies with wave-vector components parallel to the wire are obtained. After having quantized the phonon field we derive the Fröhlich Hamiltonian describing the electron--LO-phonon interaction. The influence of the thickness of the barrier layer as well as the thin metallic shell on the phonon frequencies and their interaction with electrons is studied.

Equivalence Between Vector Meson Dominance and Unitarised Chiral Perturbation Theory
Authors: Tran Truong Nguyen , Dung Le Viet
Published: April 2015

It is explicitly shown that either the approximate solution of the integral equation for the inverse of the pion form facto,r or the result of the Pad\(\text{\'e}\) approximant method of resumming the one loop Chiral Perturbation Theory (CPTH) are equivalent to the standard vector meson dominance (VMD) models, using the vector meson coupling to two pseudoscalars given by the KSRF relation. Inconsistencies between the one loop CPTH and its unitarised version (or the VMD model) are pointed out. The situation is better for the CPTH calculation of the scalar form factor and the related S-wave $\pi \pi$ scattering. The branching ratios of \(\tau \to \pi^+ \pi^0 \nu \), \(\tau \to K \pi \nu \), \(\tau \to K^+ \eta \nu\) and $\tau \to K^+ \bar{K^0} \nu\) using only two inputs as the \(\rho\) and \(K^*\) masses, or the two corresponding rms radii, agree with the experimental data. Using the same number of parameters, the corresponding one loop CPTH calculation cannot explain the $\tau$ data.

Are the Borrowing Costs of Large Financial Firms Unusual?
Authors: Ahmed Javed I. , Anderson Christopher , Zarutskie Rebecca E.
Published: April 2015

Estimates of investor expectations of government support of large financial firms are often based on large financial firms&#x27; lower borrowing costs relative to smaller financial firms. Using pricing data on credit default swaps (CDS) and corporate bonds over the period 2004 to 2013, however, we find that the CDS and bond spreads of financial firms are no more sensitive to borrower size than the spreads of non-financial firms. Outside of the financial crisis period, spreads are more sensitive to borrower size in several non-financial industries. We find that size-related differences in spreads are partially driven by higher liquidity and recovery rates of larger borrowers. Prior to the financial crisis, we also find that financial firms exhibited generally lower spreads that were less sensitive to size than spreads for several other industries. Our results suggest that estimates of implicit government guarantees to financial firms may overemphasize size- related borrowing cost differentials. However, our analysis also suggests that, prior to the financial crisis, investor expectations of government support, or generally reduced risk perceptions, may have reduced borrowing costs for the financial industry as a whole.

Cartographie sémantico-lexicale et histoire des filiations étymologiques
Authors: Surmont Jean-Nicolas de
Published: April 2015

Resumo: No presente artigo propomos um análise genético-morfológica do étimo cantio até a estabilização na forma chanson. Entre o baixo latim e o francês arcaico podemos observar hesitações gráficas de tal manera que uma confusão semântico-morfológica se criou entre as formas canso y chanson: a primera pode ser considerada como a forma occitana da segunda e não como um gênero poético independente. Esta hesitação gráfica comporta ambigüidades semânticas na Idade Média pelo menos. Neste artigo analisaremos as diferentes acepções da palavra chanson em um corpus de dicionários de língua francesa.Palavras-chave: Etimologia; francês arcaico; chanson; canso.Résumé: Dans le présent article nous proposerons une analyse de génétique morphologique partant de l’étymon cantio jusqu’à l’usage stabilisé de la forme chanson. Entre le bas latin et l’ancien français des hésitations graphiques sont observées de telle manière qu’une confusion sémantico-morphologique a existé entre les formes canso et chanson l’un pouvant n’être que la forme occitane de l’autre ou plutôt un genre poétique à part entière. Cette hésitation graphique comporte donc des ambiguïtés sémantiques, au Moyen-Âge du moins. En dressant une cartographie sémantique du lexème chanson, nous analyserons les différentes acceptions du mot dans un corpus de dictionnaires de langue française.Mots-clés: Étymologie; ancien français; chanson; canso.Resumen: En el presente artículo proponemos un análisis genético morfológico del etymon cantio hasta la estabilización en la forma chanson. Entre el bajo latín y el antiguo francés podemos observar hesitaciones gráficas de tal manera que una confusión semántica-morfológica se ha creado entre las formas canso y chanson la primera puede ser considerada como la forma occitana de la segunda y no como un género poético independiente. Esta hesitación gráfica comporta ambigüedades semánticas en la Edad Media por lo menos. En este artículo analizaremos las diferentes acepciones de la palabra chanson en un corpus de diccionarios de lengua francesa.Palabras-clave: Etimología; antiguo francés; chanson; canso.Keywords: Etymologie; old French; chanson; canso.
Mídia, gêneros do discurso e transgressão
Authors: Lara Gláucia Muniz Proença
Published: April 2015

Resumo: À luz da concepção de gêneros do discurso de Mikhail Bakhtin, acrescida das contribuições de estudiosos da área de análise do discurso, examinamos, no presente artigo, três textos da mídia, de diferentes gêneros (dois anúncios publicitários e uma tira humorística), procurando enfocá-los do ponto de vista da transgressão, tomada como uma quebra de expectativa ou uma ruptura (desvio, deslocamento) de algum componente do conjunto de restrições – ou de regularidades – inerentes a um dado gênero. Nossa análise aponta para dois tipos diferentes de transgressão: a “intertextualidade intergenérica”, quando ocorre uma hibridização ou uma mescla de gêneros em que um assume a função ou a forma de outro, e a “intertextualidade intragenérica”, em que essa mescla de gêneros se dá no interior de um gênero maior, que não é afetado.Palavras-chave: Mikhail Bakhtin; gêneros do discurso; análise do discurso; mídia; transgressão; intertextualidade.Résumé: A la lumière de la conception des genres du discours chez Mikhaïl Bakhtin, à laquelle s’ajoutent les contributions de nombre de chercheurs dans le domaine de l’analyse du discours, nous nous proposons d’analyser, dans cet article, trois textes issus des médias appartenant à différents genres, dont deux publicités et une bande dessinée humoristique, sous l’optique de la transgression, prise comme une rupture de l’attente (déplacement) ou d’un élément dans l’ensemble des restrictions – ou régularités – inhérentes à un genre donné. Notre analyse indique deux types distincts de transgression: l’intertextualité inter-générique, lorsqu’il y a une hybridation ou un mélange de genres où un genre assume la fonction ou la forme d’un autre, et l’intertextualité intra-générique, où ce mélange de genres se donne à l’intérieur d’un genre prédominant, qui, à son tour, n’est pas déstabilisé.Mots-clés: Mikhail Bakhtin; genres du discours; analyse du discours; media; transgression; intertextualité.Keywords: Mikhail Bakhtin; discourse genre; discourse analysis; media; transgression; intertextuality.
Branca, bele, bela, branca... Uma leitura intercultural de «Budapeste» de Chico Buarque
Authors: Augustin Günther
Published: April 2015

Resumo: O espanto do narrador com a brancura do corpo da heroína no romance Budapeste de Chico Buarque inspirou a pergunta se a diferença da cor de pele sugere uma diferença local e cultural. Uma leitura intercultural, como apresentada neste trabalho, confirmou que essa diferença marca o livro que se constrói a partir do encontro com o estranho na forma de línguas, pessoas, lugares, países estrangeiros, inclusive suas culinárias. Nesse encontro, o espelhamento do próprio transforma o “eu” narrativo em vários sujeitos e permite que o narrador, ao mesmo tempo, afirme e negue, aceite e rejeite, assuma e não assuma a autoria do texto e valores nele textualizados, entre eles sua auto-estima como pai, marido, autor anônimo, imigrante subalterno e amante da sua professora de húngaro.Palavras-chave: Chico Buarque; Budapeste; interculturalidade.Resumen: El espanto del narrador por la blancura del cuerpo de la heroína en la novela Budapeste de Chico Buarque inspiró la pregunta sobre si la diferencia del color de la piel sugiere una diferencia local y cultural.

En ese encuentro, el reflejo de lo propio transforma el Yo narrativo en varios sujetos y permite que el narrador, al mismo tiempo, afirme y niegue, acepte y rechace, asuma y no asuma la autoría del texto y los valores allí textualizados, entre ellos su auto-estima como padre, marido, autor anónimo, inmigrante subalterno y amante de su profesora de húngaro.  Palabras-clave: Chico Buarque; Budapeste; interculturalidad.Keywords: Chico Buarque; Budapeste; interculturality.
O lugar filosófico da negociação, no romance «Teatro», de Bernardo Carvalho
Authors: Araújo André Luís de
Published: April 2015

Resumo: A leitura do romance Teatro (1998), de Bernardo Carvalho, incita-nos ao questionamento das condições nas quais se produz e se comunica o saber, uma vez que o já acalorado debate em torno dos Estudos Culturais, conforme defendido por Néstor García Canclini, Walter Mignolo, Homi Bhabha, Edward Said, entre outros, demonstrou não existir um local geográfico ou epistemológico privilegiado que detenha os direitos de propriedade sobre as práticas teóricas, mas apenas um “local filosófico” de discussão.Palavras-chave: Bernardo Carvalho; Teatro; estudos culturais; filosofia.Resumen: La lectura de la novela Teatro (1998), de Bernardo Carvalho, nos incita al cuestionamiento de las condiciones en las que se produce y se comunica el saber, una vez que el  candente debate en torno a los Estudios Culturales, conforme defendido por Néstor García Canclini, Walter Mignolo, Homi Bhabha, Edward Said, entre otros, demostró no existir un local geográfico o epistemológico privilegiado que detenga los derechos de propiedad sobre las prácticas teóricas, sino apenas un “local filosófico” de discusión.Palabras-clave: Bernardo Carvalho; Teatro; estudios culturales; filosofía.Keywords: Bernardo Carvalho; Teatro; cultural studies; philosophy.
La proposition concessive dans la poésie des troubadours
Authors: Haefele Sybille
Published: April 2015

Resumo: Este estudo visa apresentar as possibilidades da expressão concessiva na poesia dos trovadores dos séculos XII e XIII. De uma figura retórica inicial, a concessão torna-se uma noção gramatical, a partir do século XVII. No século XIX, os gramáticos a definem como uma proposição que, mesmo colocando obstáculo a uma ação, não a impede de ocorrer. Uma análise dos cancioneiros provençais mostra relações de sinonímia sintática entre as formas concessivas e suas variantes, o que pode confirmar os laços de parentesco, que devem, supostamente, existir entre os manuscritos.Palavras-chave: Trovador; poesia; Idade Média; concessão; provençal.Résumé: Cette étude vise à présenter les possibilités de l’expression concessive dans la poésie des troubadours des XIIe et XIIIe s. D’une figure rhétorique initiale, la concession devient une notion grammaticale dès le XVIIe. Au XIXe s. les grammairiens la définissent comme une proposition qui, tout en mettant obstacle à une action, ne l’empêche pas d’avoir lieu. Une analyse des chansonniers provençaux rélève des rapports de synonymie syntaxique entre les formes concessives et leurs variantes, ce qui semble confirmer les liens de parenté supposés exister entre les manuscrits.Mots-clés: Troubadour; poesie; Moyen Âge; concession; provençal.Keywords: Troubadour; poetry; Middle Ages; concession; provençal.
«Fábula virtual»: uma análise sociossemiótica
Authors: Queiroz Rita de Cássia Ribeiro
Published: April 2015

Resumo: O presente trabalho tem por tema a análise sociossemiótica do texto “Fábula virtual”, de Flávia Varella, publicado na revista VEJA, de 29 de outubro de 1997, às páginas 106 a 108. A opção pela análise sociossemiótica de um texto não-literário deve-se ao fato de que é através deste tipo de investigação textual que se pode reconstituir o funcionamento dos diversos sistemas de significação da língua. E, a partir dessa reconstituição, reconhecer os traços socioculturais, ideológicos, sistema de valores e visão de mundo de uma determinada comunidade sociolingüística e cultural.Palavras-chave: Flávia Varella; Fábula virtual; sociossemiótica; cultura.Resumen: El presente trabajo tiene por tema el análisis sociossemiótico del texto “Fábual virtual”, de Flávia Varella, publicado en el periódico Veja, de 29 de octubre de 1997, a las páginas 106 a 108.
