An Interpretation of the Continuous Adaptation of the Self/Environment Process
Insights into the nondual relationship of organism and environment and their processual
nature have resulted in numerous efforts at understanding human behavior and motivation from a
holistic and contextual perspective. Meadian social theory, cultural historical activity theory (CHAT),
ecological psychology, and some interpretations of complexity theory persist in relating human activity
to the wider and more scientifically valid view that a process metaphysics suggests. I would like to
articulate a concept from ecological psychology – that of the affordance, and relate it to aspects of
phenomenology and neuroscience such that interpretations of the self, cognition, and the brain are
understood as similar to interpretations of molar behaviors exhibited in social processes. Experience
with meditation as a method of joining normal reflective consciousness with ‘awareness’ is described
and suggested as a useful tool in coming to better understand the nondual nature of the body
Un portale per l’archeologia medievale
Thanks to the great development in the use of the Internet, even in Archaeology the Net can be exploited both as a means to spread new research results, and to create a dialogue between different institutions like Universities, Superintendences, archaeological and cultural associations. Nowadays, through thousands of web sites, users have acquired a good experience in surfing and are able to choose which site to visit and not. This article presents a detailed description of our web site for Medieval Archaeology, which counts more than 6000 web pages since it was put on line in 1996. It has become a benchmark and a starting point for every kind of research in medieval archaeology on the Interne
Electrical impedance tomography to set positive end-expiratory pressure
Purpose of review:To summarize the rationale and concepts for positive end-expiratory pressure (PEEP) setting with electrical impedance tomography (EIT) and the effects of EIT-based PEEP setting on cardiopulmonary function. Recent findings:EIT allows patient-specific and regional assessment of PEEP effects on recruitability and overdistension, including its impact on ventilation-perfusion (V/Q) mismatch. The overdistension and collapse (OD-CL) method is the most used EIT-based approach for PEEP setting. In the RECRUIT study of 108 COVID-19 ARDS patients, the PEEP level corresponding to the OD-CL crossing point showed low overdistension and collapse (below 10% and 5%, respectively) regardless of recruitability. In a porcine model of acute respiratory distress syndrome (ARDS), it was shown that at this crossing point, respiratory mechanics (compliance, DP) were consistent, with adequate preload, lower right ventricular afterload, normal cardiac output, and sufficient gas exchange. A recent meta-analysis found that EIT based PEEP setting improved lung mechanics and potentially outcomes in ARDS patients. EIT thus provides critical insights beyond respiratory mechanics and oxygenation for individualized PEEP optimization. EIT-based methods for PEEP setting during assisted ventilation have also been proposed.Summary:EIT is a valuable technique to guide individualized PEEP setting utilizing cardiopulmonary information that is not captured by respiratory mechanics and oxygenation response alone.</p
l archeologia dell elevato come archeologia
A seguito della recente comparsa in Italia di numerosi studi dedicati all'archeologia dell'architettura, si vuole proporre con questo contributo una riflessione sui rapporti tra la stratigrafia verticale e quella orizzontale e, in particolare, sui rapporti tra l'indagine dell'evidenza materiale (strutture verticali) e la sua interpretazione. In questo contesto si presentano alcuni studi coordinati dall'Insegnamento di Archeologia Medievale dell'Università di Siena, riguardanti progetti realizzati intorno alla nascita e allo sviluppo dei castelli, con particolare riferimento alla Toscana centro meridionale

Colline Metallifere (Tuscany, Italy)
Since the 1980s, in Italy, and Tuscany in particular, considerable experience has been developed in research on the mining landscape in relation to the geography of population, with particular attention to the Medieval period. Numerous research projects carried out in the Colline Metallifere areas of Livourne and Grosseto by the Archaeology Department of the University of Sienna (Prof. Riccardo Francovich) have revealed the huge potential offered by this territory for the study of the population, extraction and production dynamics of the pre-industrial period as well as the necessity for rigorous surveillance of the remains of these activities which have been progressively eroded by recent and massive extraction activities and by the current development of housing and infrastructure. In the Livourne Colline Metallifere area, we have already advanced from the research phase to the creation of a fully operational Archaeo-mining Park which has made it possible to protect an extensive territory containing a wealth of pre-industrial and industrial archaeological evidence, including the mining village of Rocca San Silvestro. In the Grosseto province, the Colline Metallifere grossetane Technological and Archaeological Park was recently created. The aim of this institution is to preserve and enhance historical and archaeological heritage of prime importance which twenty years of research have contributed to uncover across a vast territory.Depuis les années 80, en Italie, et en particulier en Toscane, une expérience considérable d’étude du paysage minier en relation avec la géographie du peuplement s’est développée, avec une attention particulière pour la période médiévale. Les nombreuses recherches menées dans la zone des Colline Metallifere de Livourne et de Grosseto par le Département d’Archéologie de l’Université de Sienne (prof. Riccardo Francovich) ont mis en évidence le potentiel énorme de ce territoire pour l’étude des dynamiques de peuplement, d’extraction et de production d’époque préindustrielle, ainsi que la nécessité d’une surveillance rigoureuse des vestiges de ces activités progressivement érodés par les activités d’extraction récentes et massives et par le développement de l’habitat et des infrastructures actuellement en cours. Dans la zone des collines métallifères de Livourne, nous sommes déjà passés de la phase de recherche à l’institution d’un Parc Archéominier pleinement opérationnel qui a permis de protéger un vaste territoire riche en témoignages archéologiques préindustriels et industriels comprenant le village minier de Rocca San Silvestro. Dans la province de Grosseto a été récemment créé le Parc Technologique et Archéologique des Colline Metallifere de Grosseto. Cette institution a pour objectif de préserver et mettre en valeur un patrimoine historique et archéologique de grande importance que vingt ans de recherches ont contribué à mettre au jour sur un vaste territoire
Physiological definition for region of interest selection in electrical impedance tomography data:description and validation of a novel method
Objective:Geometrical region of interest (ROI) selection in electrical impedance tomography (EIT) monitoring may lack sensitivity to subtle changes in ventilation distribution. Therefore, we demonstrate a new physiological method for ROI definition. This is relevant when using ROIs to compute subsequent EIT-parameters, such as the ventral-to-dorsal ratio during a positive end-expiratory pressure (PEEP) trial.Approach:Our physiological approach divides an EIT image to ensure exactly 50% tidal impedance variation in the ventral and dorsal region. To demonstrate the effects of our new method, EIT measurements during a decremental PEEP trial in 49 mechanically ventilated ICU-patients were used. We compared the center of ventilation (CoV), a robust parameter for changes in ventro-dorsal ventilation distribution, to our physiological ROI selection method and different commonly used ROI selection methods. Moreover, we determined the impact of different ROI selection methods on the PEEP level corresponding to a ventral-to-dorsal ratio closest to 1.Main results:The division line separating the ventral and dorsal ROI was closer to the CoV for our new physiological method for ROI selection compared to geometrical ROI definition. Moreover, the PEEP level corresponding to a ventral-to-dorsal ratio of 1 is strongly influenced by the chosen ROI selection method, which could have a profound clinical impact; the within-subject range of PEEP level was 6.2 cmH2O depending on the chosen ROI selection method.Significance:Our novel physiological method for ROI definition is sensitive to subtle ventilation-induced changes in regional impedance (i.e. due to (de)recruitment) during mechanical ventilation, similar to the CoV.</p
Leyes subnacionales de paridad de género y unicameralidad: Córdoba (Argentina) como caso testigo
Este estudio explora el impacto de las leyes de paridad de género vigentes en la provincia de Córdoba en los últimos veinte años. Desde su implementación, tales normativas han contemplado un criterio de paridad vertical por el cual las listas electorales deben conformarse con un porcentaje equivalente de mujeres y varones, organizado con una alternancia secuencial aplicada tanto a titulares como a suplentes. Sin embargo, el efecto de estas normativas se debilita al aplicarse en Cámaras Legislativas como la de Córdoba, organizada bajo un sistema mixto que combina bancas correspondientes a distritos plurinominales y uninominales. Este estudio analiza la composición de la Unicameral Cordobesa, evidenciando los obstáculos que imposibilitan alcanzar una composición paritaria en la Cámara. Los resultados dan cuenta también de la subrepresentación de mujeres en otros roles jerárquicos dentro de la Cámara y en los Ministerios.Fil: Francovich, Mila. Universidad Nacional de Córdoba.
