Interventi migliorativi in acciaio a tutela delle opere di interesse storico-monumentale dal rischio sismico
2007
The research concerns the analysis of structural behaviour of some historic-monumental buildings in which steel structures are used for the seismic protection. A dynamic model has been made to individuate the macro-element with an high seismic risk, that is, for church studied, the drum-dome system. Then a scaled model has been tested to determinate the evolution of the lesions, the retrofitting works, that are constituted by steel frames, bare or braced, inserted inside door/window holes of the drum-dome system, and the variation structural ductility. An elastic linear analysis, with a FEM software, has been developed for other type of buildings, in which the vertical structures are made w…
Progetto di Strutture in acciaio per le nuove costruzioni e per gli interventi di consolidamento. IV Edizione
2005
The book is a state of the art summary of recent development in the behavior, analysis and design of steel and composite structures. The book provides advanced students, researchers al professionals in civil and structural engineering with the basic principles upon which the modern codes are based. In the first part, the materials, the actions and the sectional behavior are analyzed on the base of the limit state theory. Then the connections (bolted and welded)and the stability effects are examined. In this way is possible speak about seismic performance, retrofitting an refurbishment of existing buildings, referring to the italian rules, to the european codes EC3, EC4 and to the AISC rules.
Using uncertain preferential information from stakeholders to assess the acceptability of alternative forest management plans
2017
In forest management planning, participatory planning processes are often encouraged as a means to acquire relevant information and to enhance the stakeholders' acceptability of alternative plans. This requires the aggregation of the stakeholders' preferences that can be done in a wide variety of manners. The aggregation process strives to reduce the information into a single set of preferences that simplifies the information and allows for the use of discrete decision support tools. Depending on how the preferences are aggregated, a wide range of plan rankings can emerge. Although this range of ranking complicates the issue of plan selection, it does highlight the uncertainty involved in a…
Third canal in the mesial root of permanent mandibular first molars: Review of the literature and presentation of 3 clinical reports and 2 in vitro s…
2007
Introduction. Systematic anatomical studies corroborate the anatomical complexity of the root canal system. Deviations from the norm such as multiple orifices, apical deltas, accessory canals and other variations are frequent. Objectives. To present clinical reports of mandibular molars with three canals in the mesial root and two in vitro studies of the morphology of these canals, together with a review of the literature. Materials and Methods. Three clinical reports are presented of mandibular molars where three canals in the mesial roots were treated endodontically. Two in vitro studies were performed, one using computerized tomography and the other with scanning electron microscopy, to …
Stato di eccezione e storia del diritto romano
2022
Il contributo si sofferma sull'uso della storia del diritto romano nella ricerca degli archetipi dello stato di eccezione e valuta criticamente, in particolare, le differenti ricostruzioni suggerite da Carl Schmitt e Giorgio Agamben.
Parent–Infant Attachment Insecurity and Emotional Eating in Adolescence: Mediation through Emotion Suppression and Alexithymia
2021
Contains fulltext : 233652.pdf (Publisher’s version ) (Open Access) Emotional eating (EE), the propensity to eat in response to emotions, is thought to have its origins in the early parent-infant relationship. This study tested the hypothesis that infant attachment insecurity results in EE in adolescence through the increased use of the emotion regulation strategy suppression of emotions and subsequent alexithymia. At the age of 15 months, parent-infant attachment security (n = 129) was observed with two abbreviated attachment measures: the shortened strange situation procedure (SSSP), and the shortened attachment Q-set (S-AQS). At the age of 12 years, children completed self-report questio…
Viestinnän strateginen rooli organisaatiossa : näkemyksiä viestinnän strategisesta luonteesta ja siihen vaikuttavista tekijöistä
2016
Viestinnän merkitys organisaatiossa korostuu dynaamisessa toimintaympäristössä, sillä viestintäammattilaisen ydinosaamiseen kuuluvat hyvät konfliktin hallintakyvyt sekä sidosryhmätaidot. Silti viestintäammattilaiset joutuvat edelleen paikoittain varjoon organisaation strategisista toimijoista puhuttaessa ja tämä saattaa johtaa esimerkiksi heikompaan budjetointiin sekä vähäisiin vaikuttamismahdollisuuksiin. Tutkimuksen tavoitteena oli lisätä ymmärrystä strategisen viestinnän käsitteestä ja tuoda tuoreita näkökulmia viestintäammattilaisten asemaan organisaatiossa. Tutkimuskysymyksissä pohdittiin viestintäammattilaisen strategista roolia, strategisen viestinnän määritelmää sekä viestintäammatt…
Eettisesti haastavat tilanteet ja niiden kuormittavuus johtajien työssä: fokusryhmäkeskusteluiden analyysi
2010
Tässä pilottitutkimuksessa tutkittiin laadullisesti johtajien työssään kokemia eettisesti haastavia tilanteita (sisällöt, kontekstit) sekä niissä koettuja ristiriitakokemuksia. Työtilanteita luokiteltiin laadullisen aineiston pohjalta. Aineisto kerättiin 16 suomalaisen johtajan fokusryhmäkeskusteluista (neljä ryhmää). Tulokset osoittivat, että johtajat kohtasivat usein työssään erilaisia eettisesti haastavia tilanteita suhteessa organisaation sidosryhmiin. Näitä sidosryhmiä olivat organisaation toimintaympäristö eli yhteiskunta, asiakkaat, omistajat sekä henkilöstö (johto, kollegat ja alaiset). Haastavien tilanteiden sisällöt jakautuivat viiteen luokkaan: 1) monimutkaiset työtilanteet, 2) r…
Monitoring of stress distribution in damaged small-scale masonry walls by using two innovative sensors
2023
Structural Health Monitoring (SHM) represents a strategic solution for the preservation of cultural heritage buildings. Existing masonry structures often suffer reductions in mechanical performances due to physiological aging of material constituents, external actions, and effect of catastrophic natural events. In many cases, the prompt prediction of damage in masonry elements is difficult and it can cause sudden collapses, compromising the safety of people. The proposed experimental study examines the effectiveness of two low-cost and innovative stress sensors, i.e. piezoelectric and capacitive stress sensors, for SHM of masonry structures. To this scope, the sensors were embedded in the m…
Kokopäiväpedagogiikka ja sen kehittäminen varhaiskasvatuksessa
2021
Kokopäiväpedagogiikka on noussut keskeiseksi toimintatavaksi suomalaisissa päiväkodeissa. Se on myös useissa paikallisissa varhaiskasvatussuunnitelmissa toiminnan lähtökohtana, vaikka käsitteen tieteellinen määrittely on kesken ja käytännön tulkinnat vaihtelevat. Ehkä juuri näiden syiden vuoksi aihe herättää paljon keskustelua ja kiinnostusta. Kokopäiväpedagogiikka onkin vielä toistaiseksi ennen kaikkea varhaiskasvatuksen arkisanastoa. Se voi kuitenkin tutkimuksen avulla kehittyä tieteelliseksi käsitteeksi tai – kehityksen suunnasta riippuen – keskittyä pikemminkin varhaiskasvatuksen pedagogista työtä ohjaavaksi käsitteeksi. Erityinen huomio kokopäiväpedagogiikkaa koskevissa keskusteluissa …
