Un segmento de la filosofía de Benedetto Croce. La teoría de la actividad política

La lectura analítica de los textos crocianos, mediante el aparato conceptual y el estudio de las fuentes, nos sirve para interpretar la realidad que para el filósofo práctico se define a través de la tensión entre idealidad y realidad. En el ensayo la búsqueda de una teoría modelo se define mediante el paradigma de la ética que entra en contacto con la política. De este modo, 'la teoría de la actividad política' desde descripciones empíricas y desde la abstracción de la política individualiza los atisbos de la realidad concreta que se descubren a través de actos y acciones cuyo fin es el bien común

Il potere

La discussione sul potere coinvolge due aspetti, l’essenza filosofia del potere, e il suo esercizio che si esplica nella società. Chiamando in causa la dialettica potere-libertà e il rapporto con l’autorità

Percorsi di Filosofia Politica

Il volume nasce in seguito ad attività seminariali interdisciplinari tra filosofia politica, filosofia del diritto e storia delle dottrine politiche. i seminari svolti le Universià Sapienza di Roma hanno trattato il tema della libertà, della democrazia, della felicità e della solidarità nell'ottica di una progettualità della politica

Consolidation of sugaring marble by hydroxyapatite: some recent developments on producing and treating decayed samples

Consolidation of sugaring marble (i.e., marble affected by granular disaggregation) still lacks fully effective solutions. Consequently, the use of an innovative phosphate-based treatment, aimed at bonding calcite grains by formation of hydroxyapatite at grain boundaries, has recently been proposed. In this paper, firstly a novel method for producing artificially decayed marble samples, by contact with a heating plate, is proposed. Then, some results are presented about the effectiveness and the compatibility of two different formulations of the phosphate treatment, differing in terms of concentration of the phosphate precursor (3.0 M or 0.1 M aqueous solutions of diammonium hydrogen phosphate, DAP), possible ethanol addition to the DAP solution and number of DAP solution applications (1 or 2). The results of the study point out that the new weathering method allows to obtain specimens with a gradient in microstructural and mechanical properties with thickness, just like naturally weathered samples. Both phosphate treatments were able to significantly improve marble cohesion, without causing significant changes in thermal behaviour and aesthetic appearance after treatment. The addition of small quantities of ethanol to the DAP solution seems to be a very promising method for favouring HAP formation and improving the treatment performance

Preliminary study on the use of ammonium phosphate for the conservation of marble-imitating gypsum-stuccoes

In this study, a novel method for consolidation and improvement of resistance to water of gypsum-stuccoes was preliminarily investigated. The idea is treating gypsum with an aqueous solution of diammonium hydrogen phosphate (DAP, (NH4)2HPO4) to form hydroxyapatite (HAP, Ca10(PO4)6(OH)2), which has much lower solubility than gypsum. Tests carried out on gypsum paste samples, manufactured to resemble historic stuccoes, showed that, after treatment with the DAP solution, a significant improvement in mechanical properties was achieved and brushite (CaHPO4∙2H2O) was formed (alongside some other by-products, that can be removed by an additional poultice treatment). Even if brushite is more soluble than HAP, still its formation is expected to be beneficial for stuccoes conservation, as brushite is significantly less soluble than gypsum

Preliminary results of geological characterization and geochemical monitoring of Sulcis Basin (Sardinia), as a potential CCS site

The Sulcis Basin is an area situated in SW Sardinia (Italy) and is a potential site for the development of CCS in Italy. This paper illustrates the preliminary results of geological characterization of fractured carbonate reservoir (Miliolitico Fm.) and the sealing sequence, composed by clay, marl and volcanic rocks, with a total thickness of more than 900 m. To characterize the reservoircaprock system an extensive structural-geological survey at the outcrop was conducted. It was also performed a study of the geochemical monitoring, to define the baseline conditions, measuring CO2 concentrations and flux in the study site

The discursivity of the theory of the Wilayat-i faqih as the foundation of the ideals of order and unity in the theocratic vision of power in Iran

This paper examines the relationship between order and unity in the theocratic vision of power in Iran. Starting from the analysis of the theory of the Wilāyat-i faqih, the role that these terms assume within the political project of the Islamic State is studied through the analysis of the speeches of the Āyatollāh Khāmeneī. !is paper argues that Michel Foucault’s reportages on the Iranian revolution provide conceptual insights for the understanding of the Wilāyat-i faqih as an ideology which stands as an alternative to liberalism and positions itself outside the canons of Western thought. !rough highlighting the analogical symmetries between Khāmeneī’s theory of the islamic government and Khomeini’s speeches, the Wilāyat-i faqih is analyzed as a form of ideology that has emerged from the perception of a lack of order in Islamic society following the 1978 Iranian Revolution.Este artículo examina la relación entre orden y unidad en la visión teocrática del poder en Irán. Partiendo del análisis de la teoría de la Wilāyat-i faqih, se estudia el papel que estos términos asumen dentro del proyecto político del Estado Islámico a través del análisis de los discursos del Āyatollāh Khāmeneī. Este artículo argumenta que los reportajes de Michel Foucault sobre la revolución iraní brindan conocimientos conceptuales para la comprensión de la Wilāyat-i faqih como una ideología que se erige como una alternativa al liberalismo y se posiciona fuera de los cánones del pensamiento occidental. Al resaltar las simetrías analógicas entre la teoría del gobierno islámico de Khāmeneī y los discursos de Khomeini, el Wilāyat-i faqih se analiza como una forma de ideología que surgió de la percepción de falta de orden en la sociedad islámica después de la Revolución iraní de 1978

Consolidation of porous carbonate stones by an innovative phosphate treatment: Mechanical strengthening and physical-microstructural compatibility in comparison with TEOS-based treatments

For preservation of stones used in Cultural Heritage, affected by weathering processes that threaten their cohesion and mechanical properties, the application of consolidants is a common practice. However, available consolidating products generally exhibit some drawbacks that hinder their performance, in terms of either mechanical efficacy, compatibility with the substrate and/or durability. Ethyl silicate is currently the most widely used among stone consolidants; nevertheless, its reduced efficacy on calcitic substrates, together with its temporary hydrophobicity, its tendency to crack and its common formulation with volatile organic solvent, make the research for alternative consolidants for carbonate stones necessary. In this paper, a recently proposed new consolidation treatment based on the formation of hydroxyapatite inside the stone was tested on two different porous carbonate stones (Globigerina Limestone and Giallo Terra di Siena), and compared with TEOS-based treatments, frequently used for the consolidation of these lithotypes. The results show that the hydroxyapatite treatment exhibits a good efficacy in terms of mechanical properties and, compared to TEOS, it causes less pronounced alterations in open porosity and water transport properties. This makes the new treatment a potentially valid alternative to TEOS, especially in those situations where the possible presence of water behind the consolidated layer (e.g. in case of rising damp, condensation or infiltration) might threaten the durability of the consolidation intervention

Il problema della violenza contro le donne: una interpretazione filosofica

L’articolo tratta l’attuale dibattito della violenza contro le donne attraverso una prospettiva filosofico-politica. Prende spunto dalla Convention on preventing and combating violence against women and domestic violence del 2011. Il fenomeno viene indagato su alcuni obiettivi: 1) sulla fenomenologia degli atti violenti; 2) sulle modalità con cui la violenza è percepita e su alcune dimensioni strutturali e la sua estensione che va dagli atti violenti individuali che coinvolgono situazioni di vita domestica fino ai rapporti sociali; 3) nel considerare il problema della violenza contro le donne come elemento imprescindibile per la riforma dei saperi. Su queste basi viene messa in discussione la perdita di misura che incide su una concezione dell’umano che volge al negativo facendo emergere le fragilità degli esseri umani, in particolare delle donne oggetto di violenza opacizzata.The article deals with the current debate on violence against women from a philosophical-political perspective. It is inspired by the Convention on preventing and combating violence against women and domestic violence (2011). The issue is investigated on some objectives: 1) on the phenomenology of violent acts; 2) on the ways in which violence is perceived and on some structural dimensions and its extension ranging from individual violent acts involving domestic life situations to social relationships; 3) assuming the problem of violence against women as an essential element for the reform of knowledge. On this basis, the loss of measure that affects a conception of the human that turns to the negative is questioned by bringing out the frailties of human being, in particular of women who are the object of an opaque form of violence
