LA IDENTIDAD LINGUISTICA DEL HISPANOHABLANTE Y LAS DISONANCIAS COGNITIVAS

Il lavoro affronta il tema dell\u2019alterit\ue0, propria ed altrui, nell\u2019identit\ue0 linguistica, e delle sue relazioni con la dimensione multiculturale del terzo millennio. Si tratta di rispondere alla domanda: \u201cChi \ue8 l\u2019io dal punto di vista linguistico?\u201d, domanda che viene generata a partire dalla questione fondamentale: \u201cCosa significa essere uguale a se stesso?\u201d L\u2019argomento s\u2019inserisce all\u2019interno del paradigma della complessit\ue0 che, anche se \ue8 sempre esistito come elemento costitutivo dell\u2019universo, \ue8 stato riconosciuto solo ora dal punto di vista scientifico-epistemologico. Si analizza il concetto dinamico di \u2018io\u2019 secondo le teorie di H. Hedigen e di T. Sebeok e, successivamente, si sviluppa il concetto di alterit\ue0 nella costruzione dell\u2019identit\ue0 ispanofona, con l\u2019apporto dei modelli elaborati dalla propria mente e dalla societ\ue0 in cui si \ue8 inseriti. Tra questi modelli, uno dei pi\uf9 coinvolgenti \ue8 la lingua, che obbliga a ritagliare il mondo in base alle strutture lessicali, semantiche e morfosintattiche che la costituiscono. Si commentano i processi di risonanza e dissonanza che hanno lasciato il segno nei paesi ispanoparlanti e di come l\u2019identit\ue0 \ue8 cambiata nel corso del tempo con degli aspetti differenziali secondo le diverse culture. Si fa riferimento ad alcune prospettive traduttologiche in rapporto all\u2019identit\ue0 (secondo le teorie di G. Steiner e dell\u2019Universit\ue0 di Chicago, ad esempio), tenendo conto della grande complessit\ue0 dell\u2019identit\ue0 ispanofona che \ue8 il risultato dell\u2019integrazione avuta lungo il tempo da tante culture diverse (araba, ebrea, celtica, gallica, italica, nordica). Nelle conclusioni, si ribadisce l\u2019importanza di non prendere in considerazione un\u2019unica norma linguistica ispanica perch\ue8 ogni modalit\ue0 linguistica riflette l\u2019identit\ue0 (e le dissonanze) delle diverse aree culturali ispanoparlanti

Re-start from straw

This paper describes the concept and realization of an earthquake-proof prototype to verify the appropriateness of an orphanage to be built in Haiti. The construction system utilizes mainly natural and local materials like rice straw bales and bamboo. This work is the result of a master thesis in Architecture at the Politecnico di Torino. It originates from the collaboration with Architettura senza frontiere Piemonte, an Italian NGO. The wider scope of the project is to contribute to returning to rice farming and to recognizing rice straw as an appropriate building material for Haiti. Both goals would constitute a step towards establishing an integrated social, economic, environmental, agricultural, and architectural process

The relationship between seminal leukocytes, oxidative status in the ejaculate, and apoptotic markers in human spermatozoa

The aim of this study was to investigate the relationship between seminal leukocytes, reactive oxygen species (ROS) production in the ejaculate, and markers of apoptosis in human spermatozoa. Semen samples were collected from 60 patients attending fertility clinics at the Reproductive Biology Unit at Tygerberg Academic Hospital and Vincent Pallotti Hospital, Cape Town, South Africa. The concentration of seminal leukocytes was determined and was correlated with ROS production in the ejaculate, the percentage of superoxide (·O2 )- and hydrogen peroxide (H2O2)-positive spermatozoa, glutathione activation in the ejaculate, and with markers of apoptosis in spermatozoa, namely cysteine-dependent aspartate-directed proteases (caspase)-3/7 activation, mitochondrial membrane potential (ΔΨm), and the percentage of terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL)-positive sperm. Significant correlations with the concentration of seminal leukocytes were found for ROS production in the ejaculate, the percentage of ·O2 -positive spermatozoa, and caspase-3/7 activation in the ejaculate. Leukocytospermic samples showed significantly higher ROS production, percentage of ·O2 -positive sperm, GSH activation, and caspase-3/7 activation compared to non-leukocytospermic samples. The percentage of ·O2 -positive sperm was significantly correlated with sperm ΔΨm and caspase-3/7 activation in the ejaculate. Sperm ΔΨm and TUNEL-positive sperm did not correlate with seminal leukocyte concentration. Data demonstrate that high seminal leukocyte concentrations that leads to increased seminal ROS production, and is also associated with caspase activation in the male germ cell and increased mitochondrial ROS production. The latter could possibly be a result of disturbed ΔΨm. The activation of caspase-3/7 could then follow the increased intrinsic superoxide levels due to depleted intrinsic glutathione (GSH). These cellular events might not directly and immediately lead to DNA fragmentation as an endpoint of apoptosis because of topological hindrances.Web of Scienc
