Romper el ciclo de la invisibilidad. El empleo como vía para favorecer la inclusión

"[ES] En España las posibilidades de empleo de las personas en riesgo de exclusión social no son satisfactorias. Se trata de un problema que centramos en las concepciones educativas de la enseñanza-aprendizaje inicial, que orientan minoritariamente a la formación para el empleo como a la oferta y demanda de trabajo de esos colectivos. En nuestro sistema educativo de la desatención y marginación del alumnado en riesgo de exclusión social se pasó a la educación especial; luego, a la normalización e integración, lo que condujo a la inclusión educativa. En ese momento final que nos encontramos aparecen visiones innovadoras como la escuela para todos, empleo con apoyo, y vida con apoyo que desarrollan el paradigma de la autonomía y vida independiente. [EN] Employment chances for people in risk of social exclusion are not satisfactory in Spain. This has been a problem at the core of educational conceptions concerning primary education, scarcely orientated towards the employment of such groups. In our system, from margination and neglect of our pupils in risk of social exclusion, we sent them to special education first, then to normalization and integration and finally to inclusive education. Nowadays, innovative visions such as school for all, employment and life with support are developing the model of autonomy and independent life. "

Va' dove ti porta l'eletrico 28 - progetto di una guida alternativa

Lo scopo di questo lavoro è quello di elaborare una guida turistica alternativa della città di Lisbona, facendo riferimento al percorso del Tram più ricercato, l’Elétrico 28. L’obiettivo di questo progetto di guida sarà quello di accompagnare il passeggero nel suo viaggio fornendogli non le classiche informazioni dettagliate che si potrebbero trovare in una tradizionale guida, bensì dei veri input che lo stimoleranno a voler conoscere sempre di più. Le informazioni fornite provengono, oltre che da guide classiche come Lisbona. Quello che il turista deve vedere di Fernando Pessoa, dall’esperienza diretta e dalle testimonianze degli autoctoni.

The Use Of Amido- And Imido-Functionalized Alpha Hydroxy Acids In The Creation Of Biodegradable Polyesters: An Exploration Of Va

The purpose of this thesis was to synthesize biodegradable polyesters from a wide array of functionalized ¿-hydroxy acids. The initial strategy was to use amido-functionalized ¿-hydroxy acids and 2-bromopropanoyl bromide to form amido-functionalized cyclic diesters. Then, the resulting cyclic diesters would be used in ring opening polymerization to create biodegradable polyesters. However, the spontaneous rapid degradation of the secondary amido-functionalized cyclic diester structure, as seen with 2-benzamido-hydroxyacetic acid, limited ring formation to tertiary amido-functionalized ¿-hydroxy acids. Also, the hydrophilic nature of most ¿-hydroxy acids allowed water into the crystal structure of the ¿-hydroxy acid. Then, when the ¿-hydroxy acid was used in ring forming reactions, the associated water deactivated reactive reagents and limited cyclic diester synthesis. These issues led to the synthesis of hydrophobic and tertiary amido- and imido-functionalized ¿-hydroxy acids, 2-phthalimido-2-hydroxyacetic acid and 2-(1-oxoisoindolin-2-yl) hydroxyacetic acid. The new ¿-hydroxy acids were used in two new polymerization techniques, melt polycondensation and solution polymerization, instead of ring open polymerization. Melt polycondensation and solution polymerization had shown previous success in forming oligomers of amido-functionalized ¿-hydroxy acids. Melt polycondensation was conducted by heating the monomer past its melting temperature under reduced pressure. The uncatalyzed melt polycondensation of 2-(1-oxoisoindolin-2-yl) hydroxyacetic acid created polyesters (¿ 960 g/mol). The scandium(III) trifluoromethanesulfonate enhanced melt polycondensation polymerization created slightly larger oligomers (¿ 1340 g/mol). However, 2-phthalimido-2-hydroxyacetic acid was not compatible with melt polycondensation because thermal degradation occurred. Thus, solution polymerization was conducted via Steglich esterification. Only oligomeric functionalized polyesters were formed (¿ 1060 g/mol). Future work should focus on optimization of the catalyst and the reaction conditions to obtain higher molecular weight polyesters. Also, 2-(1-oxoisoindolin-2-yl) hydroxyacetic acid should be utilized in the cyclic diester synthesis technique.

Wide QRS-complex tachycardia with variable VA-conduction: what is the mechanism?

We describe the case of a 16-year-old woman with a surgically corrected tetralogy of Fallot presenting with recurrent wide-QRS-complex tachycardia. The tachycardia could be induced and terminated with ventricular stimulation only. QRS morphology during sinus rhythm and tachycardia was identical and variable VA-conduction was observed. Mapping of the tachycardia showed that variations of HH intervals preceded VV intervals. Therefore, a mechanism involving re-entry within the bundle branches was suggested. However, detailed mapping showed cranial to caudal depolarization of the His bundle, leading to the diagnosis of atrioventricular node re-entrant tachycardia. The tachycardia was abolished by radiofrequency catheter ablation of the slow AV nodal pathway. We conclude that variable VA conduction can occur in patients with atrioventricular node re-entrant tachycardia. The atrial tissue is not always an integral part of the re-entrant circuit.
