Escala hassles & uplifts: versão em português

A escala Hassles & Uplifts avalia a intensidade da resposta a pequenos eventos cotidianos, sendo considerada um preditor de sintomas psicológicos. O objetivo deste estudo foi avaliar uma tradução da escala Hassles & Uplifts, aqui intitulada Aborrecimentos e Alegrias; para tal, realizou-se a réplica de um estudo norte-americano que mediu o desempenho, nessa escala, de indivíduos cujo padrão de comportamento fosse do tipo A ou B segundo a escala de Jenkins (Escala Aborrecimentos e Alegrias). As escalas Aborrecimentos e Alegrias e A/B foram aplicadas em 145 universitários brasileiros. Os resultados mostraram que: 1) as pontuações médias de Aborrecimentos e Alegrias foram similares às do estudo norte-americano, exceto pelos Aborrecimentos dos participantes tipo B; 2) a intensidade das Alegrias dos participantes tipo A foi significativamente superior à dos tipo B, como na literatura; 3) a intensidade de Alegrias e Aborrecimentos não diferiu entre os dois tipos, provavelmente devido à especificidade da época do teste. Concluiu-se que o padrão e a consistência dos resultados indicam que a tradução pode ser utilizada como instrumento confiável de pesquisa.

Un modelo de riesgo de crédito basado en opciones compuestas con barrera. Aplicación al mercado continuo español

In this work the valuation methodology of compound option written on a downand-out call option, developed by Ericsson and Reneby (2003), has been applied to deduce a credit risk model. It is supposed that the firm has a debt structure with two maturity dates and that the credit event takes place when the assets firm value falls under a determined level called barrier. An empirical application of the model for 105 firms of Spanish continuous market is carried out. For each one of them its value in the date of analysis, the volatility and the critical value are obtained and from these, the default probability to short and long-term and the implicit probability in the two previous probabilities are deduced. The results are compared with the ones obtained from the Geskemodel (1977).

Sustainable Concrete Pavements: A Manual of Practice, January 2012

Sustainable Concrete Pavements: A Manual of Practice is a product of the National Concrete Pavement Technology Center at Iowa State University’s Institute for Transportation, with funding from the Federal Highway Administration (DTFH61-06-H-00011, Work Plan 23). Developed as a more detailed follow-up to a 2009 briefing document, Building Sustainable Pavement with Concrete, this guide provides a clear, concise, and cohesive discussion of pavement sustainability concepts and of recommended practices for maximizing the sustainability of concrete pavements. The intended audience includes decision makers and practitioners in both owner-agencies and supply, manufacturing, consulting, and contractor businesses. Readers will find individual chapters with the most recent technical information and best practices related to concrete pavement design, materials, construction, use/operations, renewal, and recycling. In addition, they will find chapters addressing issues specific to pavement sustainability in the urban environment and to the evaluation of pavement sustainability. Development of this guide satisfies a critical need identified in the Sustainability Track (Track 12) of the Long-Term Plan for Concrete Pavement Research and Technology (CP Road Map). The CP Road Map is a national research plan jointly developed by the concrete pavement stakeholder community, including Federal Highway Administration, academic institutions, state departments of transportation, and concrete pavement–related industries. It outlines 12 tracks of priority research needs related to concrete pavements. CP Road Map publications and other operations support services are provided by the National Concrete Pavement Technology Center at Iowa State University.

Overexpression of catalase prevents gentamicin – induced apoptosis of renal proximal tubular cells in transgenic mice.

Introduction : La néphrotoxicité est une complication majeure de la gentamicine, qui est largement utilisée dans le traitement des infections bactériennes, en particulier celles provoquées par des bactéries à Gram-négatif. La gentamicine induit l'apoptose tubulaire, mais les mécanismes moléculaires impliqués demeurent mal compris. Dans l’étude présente, nous avons examiné le rôle des espèces réactives de l'oxygène (ROS) , des proteins Bax, Bmf et Caspase-12 (Csp-12) dans le mécanisme d’action de la gentamicine sur l'apoptose des tubules proximaux rénaux (RPT) et les dommages rénaux induits par ce médicament chez la souris. Méthode: Des souris adultes (âgées 18-19 semaines) mâles non-Tg et des souris transgéniques (CAT-Tg) qui surexpriment la catalase spécifiquement dans leurs cellules des RPT ont été traitées par injections intra-péritonéales de gentamicine (20 mg/kg/jour) pour 5 jours consécutifs, puis euthanasiés. Les reins ont été examinés et analysés par histologie, immunohistochimie pour presansance de la stress oxidative, expression des proteins Bax, Bmf et Csp-12 et essai TUNEL pour étudier de l’apoptose . Nous avons aussi examiné l'effet de la gentamicine sur génération des ROS et l’apoptose dans les cellules RPTC immortalisées de rat (IRPTC) in vitro. Résultats: In vivo, chez les souris non-Tg, la gentamicine induit une tubulopathie et l'apoptose des RPT , stimule la production de ROS et induit une augmentation de Bax et Bmf détectée par immunohistochimie et augmont activité du caspase-12. Ces changements sont atténués chez les souris Cat-Tg. In vitro, la gentamicine induit l’apoptos des cellulles. Le co-traitement avec la catalase normalise ces effets dans les IRPTC. Conclusion : Ces données démontrent que l'apoptose des RPTC induite par la gentamicine s’effectue, au moins en partie, par l'intermédiaire de la génération des ROS.

Actuación de UNAMID (operación híbrida de la Unión Africana y las Naciones Unidas en Darfur) en la defensa de los Derechos Humanos de las mujeres en el conflicto en Darfur (2008 – 2012)

El interés de esta monografía es analizar los alcances y las limitaciones de la actuación de UNAMID en la defensa de los Derechos Humanos de las mujeres en el conflicto en Darfur (2008-2012). Lo anterior, para dar cuenta de que si bien UNAMID ha tenido avances significativos en el aumento de denuncias por violación sexual, en la educación y en la inclusión de la mujer en Darfur, la intervención tardía, la falta de personal cualificado y el lento despliegue ha limitado su actuación para erradicar la violencia sexual como arma de guerra. Sin embargo, la baja internalización de la norma por parte del Estado de Sudán ha sido el mayor limitante para la Misión de Paz. Este análisis se realiza mediante el concepto de Responsabilidad de proteger y el enfoque de Alexander Wendt y Nicholas Onuf.

A healable supramolecular polymer blend based on aromatic π-π stacking and hydrogen bonding interactions

An elastomeric, supramolecular healable polymer blend, comprising a chain-folding polyimide and a telechelic polyurethane with pyrenyl endgroups, is compatibilised by aromatic π−π stacking between the π-electron-deficient diimide groups and the π-electron-rich pyrenyl units. This inter-polymer interaction is key to forming a tough, healable, elastomeric material. Variable temperature FTIR analysis of the bulk material also conclusively demonstrates the presence of hydrogen bonding, which complements the π–π stacking interactions. Variable temperature SAXS analysis shows that the healable polymeric blend has a nanophase-separated morphology, and that the X-ray contrast between the two types of domain increases with increasing temperature, a feature that is repeatable over several heating and cooling cycles. A fractured sample of this material reproducibly regains more than 95% of the tensile modulus, 91% of the elongation to break, and 77% of the modulus of toughness of the pristine material.

Competitive strategy revisited: contested concepts and dynamic capabilities

Strategy is a contested concept. The generic literature is characterized by a diverse range of competing theories and alternative perspectives. Traditional models of the competitive strategy of construction firms have tended to focus on exogenous factors. In contrast, the resource-based view of strategic management emphasizes the importance of endogenous factors. The more recently espoused concept of dynamic capabilities extends consideration beyond static resources to focus on the ability of firms to reconfigure their operating routines to enable responses to changing environments. The relevance of the dynamics capabilities framework to the construction sector is investigated through an exploratory case study of a regional contractor. The focus on how firms continuously adapt to changing environments provides new insights into competitive strategy in the construction sector. Strong support is found for the importance of path dependency in shaping strategic choice. The case study further suggests that strategy is a collective endeavour enacted by a loosely defined group of individual actors. Dynamic capabilities are characterized by an empirical elusiveness and as such are best construed as situated practices embedded within a social and physical context.
