LA EDUCACIÓN EN DERECHOS HUMANOS DESDE UNA APROXIMACIÓN LÚDICA: EL MODELO DE NACIONES UNIDAS

Los juegos de rol conocidos como “Modelos de Naciones Unidas” permiten construir una perspectivacognitiva y cultural innovadoras, puesto que nos obligan a posicionarnos frente a los actualesdesafíos internacionales desde un nuevo lugar: el del Otro. El mayor desafío pasa por representarfielmente la política exterior de aquel país que se representa, y así este ejercicio abre ventanas amundos desconocidos que rompen con estructuras mentales e imaginarios colectivos sobre los quese asientan el prejuicio y la discriminación negativa. Debe sumarse el enfoque interdisciplinariosobre el que se construye la práctica: las situaciones por problematizar exigen un esfuerzo conceptual ampliado y holístico para obtener una propuesta superadora.Tomando como caso testigo el 4º MONUUNQ (2009) se intentará sostener la idea de que la actuaciónlogra habilitar saberes, competencias y perspectivas cognitivas nuevas para la persona que,en su insistencia y ejercicio, progresivamente consigue ir construyendo un empoderamiento real.Tarde o temprano, el sujeto activo en dichas prácticas, trasladará el aprendizaje a su vida cotidianay potenciará una verdadera educación en derechos humanos.La “mediación normativa” sucede en el espacio público, lugar desde donde se debe luchar por serreconocido por los pares, con y desde los otros, puesto que para obtener una negociación activa y unliderazgo fructífero que se plasme en el documento escrito final, el estudiante deberá mantenerse en el margen de los códigos de la diplomacia internacional: oratoria, respeto al protocolo, conocimientode los procedimientos, y defensa irrenunciable a los valores constituyentes de la ONU.AbstractRole plays known as ‘United Nations Models’ allow us to build an innovative cognitive and cultural perspective,since they make us be positioned in front of contemporary international challenges from a new place:the other’s place. The biggest challenge is to truly represent the international policy of the country being represented, and that is how this exercise opens windows to unknown worlds which break mental structuresand collective imaginaries, above which prejudice and negative discrimination settle. The interdisciplinaryfocus upon which the practice is built has to be added: the simulated situations demand a wider and holisticconceptual effort to obtain an overcoming proposal.Taking as a model 4th MONUUNQ (2009), it is intended to sustain the idea that role playing habilitatesnew skills, competences and cognitive perspectives for the person who, with insistence and exercise, willprogressively build a real empowerment. Sooner or later, the active subject on those practices will move thelearnt contents to his everyday life and will propel an actual Human Rights Education.‘Normative mediation’ takes place in the public space, the place from which people should fight to be recognizedby equals, ‘with and from other people’, since to obtain an active negotiation and fruitful leadershipwhich will turn into a final written document, the student will have to abide by the codes of internationaldiplomacy – oratory, protocol respect, procedure acknowledge, and defense of the constitutive values of United Nations Organization.

Italian higher education students’ perspectives on internationalization at home and their identity as English as lingua franca users

This study aims to explore the Italian students’ perspectives on using English in English-medium instruction (EMI) programs in light of the practices of internationalization at home (IaH) at the University of Bologna (UNIBO) in Italy and further investigates whether these attitudes affect their language identity as English as lingua franca (ELF) users. To serve this aim, a mixed-method approach was adopted to collect quantitative and in-depth qualitative data in two phases through an online survey and a semi-structured interview. A total number of 78 Italian students participated in the survey, out of which 14 participants were interviewed. The findings of the online survey indicated that most participants (92%) held a positive perspective toward the use of English in EMI programs and the findings from the interviews were in line with the results of the survey. However, the purpose of the interviews was to explore the participants’ views on their language identity as ELF users. Thematic analysis of the interviews revealed that students experience emotional, cognitive, and social transitions in EMI programs in response to their shift from a non-EMI to an EMI academic setting. Overall, all the above-mentioned transitions were positive and could lead to personal development. However, it can be concluded that the EMI context provides few opportunities for the emergence of significant new subject positions mediated by English in this study. The focus on students’ perspectives on the use of English in EMI programs can contribute to the improvement in language policy planning and internationalized curriculum design by policymakers and alleviate tensions over the controversial issue of the Englishization of higher education by considering how EMI students perceive their use of English as ELF users not superior standard English users.

Innovative electrospun nanofibers for improving delamination resistance and damping of CFRP laminates

Carbon Fiber Reinforced Polymers (CFRPs) are well renowned for their excellent mechanical properties, superior strength-to-weight characteristics, low thermal expansion coefficient, and fatigue resistance over any conventional polymer or metal. Due to the high stiffness of carbon fibers and thermosetting matrix, CFRP laminates may display some drawbacks, limiting their use in specific applications. Indeed, the overall laminate stiffness may lead to structural problems arising from their laminar structure, which makes them susceptible to structural failure by delamination. Moreover, such stiffness given by the constituents makes them poor at damping vibration, making the component more sensitive to noise and leading, at times, to delamination triggering. Nanofibrous mat interleaving is a smart way to increase the interlaminar fracture toughness: the use of thermoplastic polymers, such as poly(ε- caprolactone) (PCL) and polyamides (Nylons), as nonwovens are common and well established. Here, in this PhD thesis, a new method for the production of rubber-rich nanofibrous mats is presented. The use of rubbery nanofibers blended with PCL, widely reported in the literature, was used as matrix tougheners, processing DCB test results by evaluating Acoustic Emissions (AE). Moreover, water-soluble electrospun polyethylene oxide (PEO) nanofibers were proposed as an innovative method for reinforcing layers and hindering delamination in epoxy-based CFRP laminates. A nano-modified CFRP was then aged in water for 1 month and its delamination behaviour compared with the ones of the commercial laminate. A comprehensive study on the use of nanofibers with high rubber content, blended with a crystalline counterpart, as enhancers of the interlaminar properties were then investigated. Finally, PEO, PCL, and Nylon 66 nanofibers, plain or reinforced with Graphene (G), were integrated into epoxy-matrix CFRP to evaluate the effect of polymers and polymers + G on the laminate mechanical properties.

Cluster Analysis To Identify Elderly People's Profiles: A Healthcare Strategy Based On Frailty Characteristics.

The new social panorama resulting from aging of the Brazilian population is leading to significant transformations within healthcare. Through the cluster analysis strategy, it was sought to describe the specific care demands of the elderly population, using frailty components. Cross-sectional study based on reviewing medical records, conducted in the geriatric outpatient clinic, Hospital de Clínicas, Universidade Estadual de Campinas (Unicamp). Ninety-eight elderly users of this clinic were evaluated using cluster analysis and instruments for assessing their overall geriatric status and frailty characteristics. The variables that most strongly influenced the formation of clusters were age, functional capacities, cognitive capacity, presence of comorbidities and number of medications used. Three main groups of elderly people could be identified: one with good cognitive and functional performance but with high prevalence of comorbidities (mean age 77.9 years, cognitive impairment in 28.6% and mean of 7.4 comorbidities); a second with more advanced age, greater cognitive impairment and greater dependence (mean age 88.5 years old, cognitive impairment in 84.6% and mean of 7.1 comorbidities); and a third younger group with poor cognitive performance and greater number of comorbidities but functionally independent (mean age 78.5 years old, cognitive impairment in 89.6% and mean of 7.4 comorbidities). These data characterize the profile of this population and can be used as the basis for developing efficient strategies aimed at diminishing functional dependence, poor self-rated health and impaired quality of life.

Chemical Immobilization Of Crosslinked Polymeric Ionic Liquids On Nitinol Wires Produces Highly Robust Sorbent Coatings For Solid-phase Microextraction.

Super elastic nitinol (NiTi) wires were exploited as highly robust supports for three distinct crosslinked polymeric ionic liquid (PIL)-based coatings in solid-phase microextraction (SPME). The oxidation of NiTi wires in a boiling (30%w/w) H2O2 solution and subsequent derivatization in vinyltrimethoxysilane (VTMS) allowed for vinyl moieties to be appended to the surface of the support. UV-initiated on-fiber copolymerization of the vinyl-substituted NiTi support with monocationic ionic liquid (IL) monomers and dicationic IL crosslinkers produced a crosslinked PIL-based network that was covalently attached to the NiTi wire. This alteration alleviated receding of the coating from the support, which was observed for an analogous crosslinked PIL applied on unmodified NiTi wires. A series of demanding extraction conditions, including extreme pH, pre-exposure to pure organic solvents, and high temperatures, were applied to investigate the versatility and robustness of the fibers. Acceptable precision of the model analytes was obtained for all fibers under these conditions. Method validation by examining the relative recovery of a homologous group of phthalate esters (PAEs) was performed in drip-brewed coffee (maintained at 60 °C) by direct immersion SPME. Acceptable recoveries were obtained for most PAEs in the part-per-billion level, even in this exceedingly harsh and complex matrix.

In Vitro Effects Of Hydrogen Peroxide Combined With Different Activators For The In-office Bleaching Technique On Enamel.

Abstract Objective. The aim of this study was to evaluate the alteration of human enamel bleached with high concentrations of hydrogen peroxide associated with different activators. Materials and methods. Fifty enamel/dentin blocks (4 × 4 mm) were obtained from human third molars and randomized divided according to the bleaching procedure (n = 10): G1 = 35% hydrogen peroxide (HP - Whiteness HP Maxx); G2 = HP + Halogen lamp (HL); G3 = HP + 7% sodium bicarbonate (SB); G4 = HP + 20% sodium hydroxide (SH); and G5 = 38% hydrogen peroxide (OXB - Opalescence Xtra Boost). The bleaching treatments were performed in three sessions with a 7-day interval between them. The enamel content, before (baseline) and after bleaching, was determined using an FT-Raman spectrometer and was based on the concentration of phosphate, carbonate, and organic matrix. Statistical analysis was performed using two-way ANOVA for repeated measures and Tukey's test. Results. The results showed no significant differences between time of analysis (p = 0.5175) for most treatments and peak areas analyzed; and among bleaching treatments (p = 0.4184). The comparisons during and after bleaching revealed a significant difference in the HP group for the peak areas of carbonate and organic matrix, and for the organic matrix in OXB and HP+SH groups. Tukey's analysis determined that the difference, peak areas, and the interaction among treatment, time and peak was statistically significant (p < 0.05). Conclusion. The association of activators with hydrogen peroxide was effective in the alteration of enamel, mainly with regards to the organic matrix.

Resíduos de sisal como reforço em compósitos de polipropileno virgem e reciclado

Foram estudadas as propriedades térmicas e mecânicas de compósitos de polipropileno, virgem e reciclado, reforçados com 30% em massa de fibras residuais de sisal, assim como o perfil de processamento e a morfologia da matriz polimérica. Para tanto, foram determinadas a resistência à tração, o módulo de Young, alongamento na ruptura, e energia de impacto. As amostras também foram caracterizadas por MEV, DMTA e TG. Para ambos os compósitos de polipropileno, virgem e reciclado, com a adição das fibras, o alongamento na ruptura mostrou uma queda significativa, enquanto que a resistência à tração não sofreu grandes variações. Houve um aumento significativo nos valores de tração na ruptura e de energia de impacto com a adição das fibras de sisal na matriz de polipropileno. As análises térmicas mostraram ligações secundárias, como as ligações polares, entre as fibras e a matriz, concordando com o comportamento mecânico dos compósitos. Constatou-se que a temperatura de transição vítrea não variou após a adição da fibra.

Relação entre depressão pós-parto e disponibilidade emocional materna

A depressão pós-parto é um transtorno de alta prevalência que pode comprometer a qualidade da relação mãe-criança. Este estudo pretende determinar a prevalência do referido transtorno, comparar a interação mãe-bebê nos grupos com e sem depressão e verificar a relação entre depressão, apoio social e estilos de relacionamento e disponibilidade emocional maternos. As participantes eram gestantes que pretendiam dar à luz no Hospital Universitário da Universidade de São Paulo entre dezembro de 2006 e dezembro de 2008. A prevalência de depressão pós-parto em nossa amostra foi 28%. Não houve diferença significativa na relação mãe-criança no grupo com e sem depressão. Encontrou-se correlação positiva entre sensibilidade materna e escolaridade e entre sensibilidade e certas dimensões de apoio social e estilo de relacionamento. Conclui-se que a prevalência de depressão pós-parto em nossa amostra é mais alta que a média mundial, mas a sintomatologia depressiva não interfere significativamente na qualidade da interação mãe-bebê. A sensibilidade materna é influenciada por fatores sócio-cognitivos e afetivos.

Deformed Gaussian-orthogonal-ensemble description of small-world networks

The study of spectral behavior of networks has gained enthusiasm over the last few years. In particular, random matrix theory (RMT) concepts have proven to be useful. In discussing transition from regular behavior to fully chaotic behavior it has been found that an extrapolation formula of the Brody type can be used. In the present paper we analyze the regular to chaotic behavior of small world (SW) networks using an extension of the Gaussian orthogonal ensemble. This RMT ensemble, coined the deformed Gaussian orthogonal ensemble (DGOE), supplies a natural foundation of the Brody formula. SW networks follow GOE statistics until a certain range of eigenvalue correlations depending upon the strength of random connections. We show that for these regimes of SW networks where spectral correlations do not follow GOE beyond a certain range, DGOE statistics models the correlations very well. The analysis performed in this paper proves the utility of the DGOE in network physics, as much as it has been useful in other physical systems.

Tempering temperature effects on abrasive wear of mottled cast iron

The effects of different tempering temperatures (300-600 degrees C) on abrasive wear resistance of mottled cast iron were studied. Abrasive wear tests were carried out using the rubber-wheel test on quartz sand and the pin test on Al(2)O(3) abrasive cloths. The retained austenite content of the matrix was determined by X-ray diffraction. The wear surface of the specimens was examined by scanning electron microscopy for identifying the wear micromechanism. Bulk hardness and matrix hardness before and after the tests were measured. The results showed that in the two-body (pin-on-disc test) system, the main wear mechanism was microcutting and high matrix hardening was presented. The wear rates presented higher correlation with the retained austenite than with the bulk and matrix hardness. In the three-body system (sand-rubber wheel), the wear surfaces presented indentations due to abrasive rolling. The wear rates had better correlation with both the bulk and matrix hardness (before and after the wear test) than with the retained austenite content. There are two groups of results, high and low wear rates corresponding to each tribosystem, two-body abrasive wear and three-body abrasive wear, respectively. (C) 2009 Elsevier B.V.

Newcastle disease virus in penguins from King George Island on the Antarctic region

Here we report the isolation of Newcastle disease virus (NDV) from cloacal swabs obtained from penguins in the South Atlantic Antarctic region (62 degrees 08S, 58 degrees 25W). Samples of 100 penguins from King George Island were tested by real-time PCR, of which 2 (2%) were positive for NDV. The positive samples were isolated in embryonated chicken eggs and their matrix and fusion proteins genes were partially sequenced. This was complemented by the serological study performed on the blood of the same specimens, which resulted in a 33.3% rate of positivity. (C) 2010 Elsevier B.V. All rights reserved.
